The Operating Procedures of Wheat Precision Broadcast Machine and Common Troubleshooting
Precision broadcasting is a mechanized seeding mode with higher field productivity, so the wheat precision broadcast machine has been accepted by more and more wheat growers. To maximize the use of the machine, this article introduces the specific operation of the wheat precision broadcast machine and the common fault handling.
I. Operation Instructions of Wheat Precision Broadcast Machine
1. Driving
(1) Check the hydraulic oil level in the hydraulic tank, add hydraulic oil and check the joints before driving.
(2) Turn on the main switch, start the engine, check whether the mechanical parts of the machine are normal and fasten the safety belts.
(3) Adjust the drum speed regulator according to the structure of the crop.
(4) Start the machine from low speed, then accelerate to medium speed, and finally switch to high speed.
(5) Steer the machine on the road and turn off the machine when turning.
2. Method of Seed Feeding
(1) Adjust the feed speed regulator of the machine according to the seed flow rate, generally adjusting to the number 6.
(2) Open the feed opening, adjust the feed plate to the appropriate position and rotate the hand wheel to adjust the feeding wheel. The clearance between the wheel and the plate should be 0.2-0.3mm.
(3) Add a layer of tape to the feeding wheel to increase the feeding amount.
(4) Before feeding, check the seed distribution inside the machine. Adjust the distributing sieve from front to back and left to right to make the seed scattering uniform.
(5) During the seeding process, check the crops growing in the field, adjust the seed flow rate, and add seeds to achieve the purpose of regular seeding.
3. During the Seeding Process
(1) Open the distributing sieve and observe whether the seeds on the surface of the drum are distributed evenly; the gap between the pressing wheel and the drum should be about 2-3mm.
(2) Observe the adjustment of the pressing wheel and adjust it in time to ensure the uniformity of seeds on the drum.
(3) When passing through the field corner, ensure that the transition is smooth and no seeds are left.
(4) The seed outlet should be adjusted according to the wind direction to ensure that the seeds are scattered evenly.
II. Common Fault Treatment of Wheat Precision Broadcast Machine
1. The Machine Does Not Start
(1) Check whether the fuel is sufficient;
(2) Check if the battery is charged;
(3) Check whether the main switch is in the on state;
(4) Check if the starting switch is connected.
2. The Engine Can not Run Normally
(1) Check the spark plug line, replace it if necessary;
(2) Check whether the air filter is clean;
(3) Check whether the fuel circuit is blocked;
(4) Check whether the fuel has deteriorated;
(5) Check if the exhaust pipe is blocked.
3. Abnormal Seeding
(1) Check whether the feeding plate is properly adjusted;
(2) Check whether the feeding wheel works normally;
(3) Adjust the pressing wheel;
(4) Adjust the seed distribution sieve;
(5) Adjust the speed regulating rod.
4. Low Seeding Rate
(1) Check if the belt is intact;
(2) Check the distribution sieve for blockage or size change;
(3) Check whether the pressure wheel height is appropriate;
(4) Check whether the seed distributor is clogged;
(5) Adjust the feed speed regulator.
In summary, the wheat precision broadcast machine has been well accepted by wheat growers. It has high productivity and greatly reduces the labor intensity of farmers. In order to use the machine correctly and make the job easier, it is necessary to understand the operating procedures and common fault handling of the machine.
