The purchase of rice transplanters should be based on different uses choose different models of rice transplanter. There are mainly 2ZT-9356B type and 2ZT-7358B type seats in China. 2ZT-9356B type is suitable for northern China, with 6 lines of work, 300mm spacing, 2ZT-7358B type is suitable for southern China, 8 lines of work, spacing 238mm, two types of seat type supporting power 165F air-cooled lying Type, four-stroke, 3-horsepower diesel engine (2.4 kW, 2600 rpm). After the model is selected, it can be selected from the following aspects.
First, the choice of appearance quality
1. First of all, check the quality of the painting machine's cover. The paint film will not fall off and the surface of the paint film will shine. Plating parts, galvanized parts of the coating firmly without falling off.
2. Welded parts are firm and reliable, with no defects such as biting meat, burn-through, open welding, and flash burr. The surface of the casting should be smooth and smooth, with no holes, no sticky sand, and no meat. Connections, non-standard parts are solid and complete.
3. Complete and complete technical data such as packing list, random tools, wearing parts spare parts, and instructions.
Second, the trial operation before the purchase
1. Before starting, add fuel oil and lubricating oil as required (general factory setting is done according to the technical requirements of the instruction manual. Then, turn the working part by manual method so that the main clutch is in the engaged state and the shift lever is set to the neutral position. The crank shakes the engine slowly (do not start), combined with the transplanter clutch to check the operation of the working part, so that the planting arm should not be stuck and the phenomenon of snapping.
2. Pull the pull-out clutch handle away from the position, pull up the decompression handle, and when the hand is shaken, the hand-sensing is easy and flexible. When the shake is fast, the sound of the fuel injection of the fuel injection nozzle can be heard. While accelerating the shaking, Quickly place the pressure relief handle and the diesel engine starts to run. After the engine is running smoothly, the rice transplanter is idled for 10 minutes at a moderate speed, and is tested for 30 minutes with the transplanting speed and the walking speed.
3. When the diesel engine is running, there are no abnormal sounds such as knocking and rattling, and the diesel engine has stable rotation speed, no black smoke, no engine oil, and no resonance.
Third, check the "three leaks" when parking, check the engine air filter, cylinder block and cylinder head joints, etc., no leakage, engine oil sump, gearbox, work transmission box, chain box and other joint surface no leakage, The oil plugs, planting arms, etc. do not leak oil.
Fourth, the inspection of other components
1. The steering wheel should be flexible and free stroke should be accurate. Turn left and right to the maximum angle of 60.
2. The free travel of the pedals must be correct. When the foot pedal is depressed, the ship should be lifted with the hanging chain. When the foot pedal is released, the boat should return to its original position.
3. Each control mechanism is reliable in engagement. The gearbox and working transmission box are within the rated rotation speed. With the help of each gear of the clutch, the hanging gear should be flexible and reliable, picking up the gear smoothly, no gear shifting, skipping gear, etc. sound.
4. The positioning clutch of the transplanting device should be accurate and reliable. The correct position is: when pulling the positioning clutch of the inserting device, the planting arm should stop at the top of the cassette door. During the operation of the planting arm, it is not allowed to touch any related parts.
5. The reversing direction of the magazine is accurate. When the magazine moves to the left and right limit positions, the lateral displacement of the finger in the spiral groove stops, and the commutation is completed by 180 round grooves and the smooth transition of the spiral groove. At the same time, the belt should be rotated a certain distance.
6. When the safety clutch is blocked, it should be separated automatically. The available wood chips are placed on the top of the door, and it is normal if the planting arm stops immediately.
7. Transplanting depth adjustment mechanism should be flexible. When the lifting bar rotates, the height of the chain box relative to the barge can be changed, thereby changing the height of the transplanting arm to achieve the purpose of adjusting the depth of the rice transplanter.
8. During the operation of the stock holding institutions, see whether the 6 or 8 groups of planting arms are not pushed and pushed. The pushing stroke is 18 to 20 mm, and the gap between pusher and separating needle is between 0.5 and 1 mm. When you stop the rotation, hold the pusher in your hand and turn it from left to right. If the pusher swings right or left with abnormal noise, it means that the group of arms is not qualified. After the above checks, if the indicators meet the requirements, the quality of the rice transplanter is reliable.
