DK 1WG-4 Straight Drive Mini Tiller

1. What is Power Tiller

 

The Power Tiller machine is powered by a small diesel engine or a gasoline engine, and has the characteristics of light weight, small size and simple structure.

 

The Power Tiller is widely used in drylands, paddy fields, orchards in plains, mountains and hills. With the corresponding equipment, it can carry out operations such as pumping, power generation, spraying, spraying, etc. It can also haul the trailer for short-distance transportation. The tiller can be freely exercised in the field, which is convenient for users to use and store, eliminating the need for large agricultural machinery to enter the mountain fields. It is the best choice for farmers to replace cattle farming.

 

2. Power Tiller Structure

 

The tiller is mainly composed of working parts, frame, transmission system and power.

 

DEKEN has two main types of tillers that are produced and sold.

 

One is driven by an air-cooled gasoline engine or a water-cooled diesel engine. The belt or chain gear box is used as a transmission device. It is equipped with a rotary tiller with a width of 500-1200mm. It has good economy, but the multi-purpose expansion capacity is limited, and the structure is also It is relatively simple and suitable for use in areas with poor economic conditions and simple use.

 

The other is powered by an air-cooled diesel engine or a high-horsepower air-cooled gasoline engine. The full-shaft full gear box is used as a transmission with a rotary tiller with a width of 800-1350mm. The whole machine adopts gear transmission, the power is not damaged, the cultivating width is wide, the ploughing is deep, the adaptability is strong, all kinds of soil can adapt, the parts have good rigidity and long service life.

 

The gearbox body is made of ductile iron casting blank for higher strength and longer service life. The clutch type adopts the friction plate clutch, which can easily realize the functions of shifting and reverse gear.

 

3. Belt Drive Power Tiller & Straight Drive Power Tiller

 

Belt drive Power Tiller

 

The engine power is transmitted to the gearbox through the belt, and the clutch is used to realize the clutching of the power; the gearbox body is mostly of a monolithic structure, and the shifting portion is above, and the power output part, the power output shaft part and the shifting part are below Chain drive is generally used between them.

 

Belt drive Power Tiller advantages

 

(1) Generally, it is powered by a general-purpose gasoline engine or a small water-cooled diesel engine. The whole machine is light in weight and convenient to transport;

 

(2) Low manufacturing cost;

 

(3) Due to the belt transmission, the impact force on the power mechanism can be reduced, and the engine has a certain protective effect;

 

(4) This model has great advantages in greenhouses, loose dry land, deep paddy fields, small fields and other geographical operations, and is one of the most popular best-selling models on the market.

 

Belt drive Power Tiller Insufficient

 

(1) If the general-purpose gasoline engine is used as the power, there are shortcomings such as high fuel consumption, low profit, and poor reliability of the power itself. Therefore, most manufacturers choose to use a 6-horsepower small-sized water-cooled diesel engine as the power source except for the export;

 

(2) Due to the use of the belt tension clutch, the belt has been re-folded and tensioned, the belt continues to heat and prone to aging break;

 

(3) The maximum output speed of this type of machine is generally about 150 rpm -180rpm, due to the higher output speed, the output torque becomes smaller, it is easy to exceed the maximum output torque of the engine during use, so the operation often appears Engine stalling or engine output speed is rapidly declining, etc., causing great damage to the engine; in particular, many manufacturers arbitrarily widen the cultivating width, increase the diameter of the tool, increase the output speed, cause frequent power failures, and use the general gasoline engine as the power. The sales volume of the micro tillage machine in the market has shrunk severely;

 

(4) Because the output end is transmitted by chain, the chain is easy to be elongated and broken;

 

(5) Because these models are lighter in weight, generally around 45-70Kg, for hard and board land into the soil is poor, farming is difficult.

 

Straight drive Power Tiller

 

The general structure is that the engine and the gearbox are directly connected by a flange, and the power is directly transmitted to the gearbox through the wet friction clutch or the cone friction clutch, and the gearbox and the walking box are integrated, and the gearbox has a main shaft. The auxiliary shaft, the reverse shaft, and the three kinds of shafts. By shifting the positions of the double spur gears on the main shaft and the reverse shaft, the fast, slow and reverse gears can be realized, and after two sets of straight bevel gears are reversed and decelerated. Will power output.

 

Straight Drive Power Tiller Advantages

 

(1) Compact structure;

 

(2) The parameters of fast speed, slow speed and reverse speed are reasonable;

 

(3) Generally use F178, F186 air-cooled diesel engine for power, the power itself is better reliability;

 

(4) The weight of the whole machine is generally about 100Kg, its farming effect is good, the operation efficiency is high, and the scope of application is wide;

 

(5) This model is the most popular best-selling model on the market and is accepted by the general users. If it enters the market, it can save a lot of promotion and promotion expenses.

 

(6) This model has great advantages in hard ground, field block, shallow paddy field, and blisters.

 

Straight Drive Power Tiller Insufficient

 

(1) If the general gasoline engine is used as the power, the power is easily damaged. If the water-cooled diesel engine is used as the power, the weight of the whole machine is heavy and the transportation is difficult; therefore, it is better to choose the F178 and F186 air-cooled diesel engines for the power matching.

 

(2) The two shafts of the auxiliary shaft and the reverse shaft in the gearbox are all cantilever beam structures, which have poor rigidity and the gears are not easily damaged due to uneven force;

 

(3) Due to the use of two sets of straight bevel gears for commutation, deceleration and the use of taper bearings to overcome the axial component of the bevel gears, the chassis part is more expensive to manufacture.

5. Power Tiller common operation misunderstanding

 

The following is a description of some misunderstandings of the power tiller machines for farmers, which is convenient for farmers to regulate the use of micro tillage machines to ensure personal safety.

 

(1) The tiller lifts the clutch when starting. Such an operation is liable to cause excessive wear on the clutch assembly and its transmission member, and may cause the agricultural machine to stall in severe cases. Therefore, the clutch pedal should be released slowly when starting, and the throttle should be appropriately increased.

 

(2) Long-term pedal clutch pedal. When driving on uneven road surface, the clutch pedal will cause the clutch to be in a semi-detached state, which will aggravate the wear of the clutch friction plate.

 

(3) Throw the throttle after the diesel tiller starts or before the flame is extinguished. The compression ratio of the diesel engine is greater than that of the gasoline engine. Suddenly increasing or decreasing the throttle is likely to cause deformation or breakage of the connecting rod and the crankshaft, increasing the carbon deposit of the cylinder piston and accelerating the wear of the moving parts.

 

(4) Standing in front of the tiller to pull the work. Some agricultural machine operators are used to walking the micro tillage machine when using the tiller, which is very unsafe. Agricultural machinery safety accidents are very likely to occur when encountering slopes, ridges or agricultural operators.

 

(5) Sliding in the neutral position when going downhill. Some agricultural operators feel that the speed of the neutral gear is faster when operating the tiller downhill, which seriously violates the safe operation rules of agricultural machinery.

 

(6) Overloading for a long time. When the tiller is working in paddy fields and harder fields, it is found that the machine emits black smoke and it is necessary to downshift in time.

 

(7) It is necessary to stop and repair the abnormal noise in time. It can be restarted after troubleshooting.

 

(8) The startup method is incorrect and it is easy to damage the boot tray. It must be started in strict accordance with the requirements of the manual.

 

(9) When turning, do not raise the handrail, use the power of the tiller to turn, and easily break the power of the tilling knife.

 

(10) Long-term squatting work is easy to make the engine poorly lubricated.

 

 

6. The wrong Power Tiller maintenance methods mainly include the following:

 

(1) Air-cooled diesel engines and gasoline engines use water to cool down. Some operators see that the engine temperature is high, worry about damage to the machine, and use watering to help cool down. In fact, it is very wrong. The water suddenly cools down, the cylinder liner shrinks suddenly, it is easy to pull the cylinder, break the ring, and even the cylinder liner is broken.

 

(2) Do not pay attention to class maintenance. Some operators think that it is enough to do maintenance once in a few days. In fact, wear and tear is a process that accumulates over a long period of time.

 

(3) Do not pay attention to the quality of fuel and lubricants. Poor fuel quality not only makes the machine power insufficient, but also accelerates the wear of the oil pump and the core sleeve; the quality of the lubricant directly affects the starting performance and service life of the machine.

 

(4) The engine cover pad is improperly used with sealant. After the sealant is used, the excess glue can easily enter the gearbox. Due to the long-term work and the suction of the oil pump, the sealant can easily block the oil inlet hole, so that the crankshaft and the connecting rod can not be effectively lubricated.

 

(5) The fuel tank cap oil leakage is sealed with film paper. After the fuel tank is sealed, a negative pressure is generated in the fuel tank after a long time of work, resulting in insufficient oil intake, causing the machine to emit black smoke while working, and the power is insufficient.

 

(6) Diesel atomization is bad only for the oil nozzle. In addition to the problem of poor diesel atomization, the high pressure oil pump wears, the pressure is small, and the oil quantity is small.

 

(7) Clench the screws on the body. The micro tillage machine is equipped with an aluminum alloy engine. The hardness of the aluminum alloy is obviously not as good as that of the ductile iron. Therefore, all the screws on the body must be pressed according to the specified torque, especially the cylinder head screws. Brushed." Also try not to tighten the screws when the machine is hot.

 

(8) Disassemble the air hood and windshield of the air-cooled machine. Some operators do not know the role of the air hood and the windshield. They think that it is a thing that blocks the earth. It can be arbitrarily disassembled, so that the wind of the fan cannot be concentrated, and the effect of cooling is lost.
