The working principle of the agricultural all-terrain crawler conveyor with the screening function is as follows: when the harvester is used, the discharging pipe of the harvester is opposite to the top of the collecting hopper 6, then the running speed of the conveyor is matched with the running speed of the harvester, the motor 12 is started, crops harvested by the harvester can enter the collecting hopper 6 through the discharging pipe, straws larger than the crops in the crops enter the crushing cylinder 9 through the feeding pipe 8 under the filtering of the filter plate 17, the rotation of the motor 12 drives the rotating shaft 13 to rotate, the fan 14 and the cam 15 rotate, the fan 14 sweeps the crops filtered by the filter plate 17, impurities smaller than the crops are swept to the outside through the filter screen 7, and in the process, the rotation of the cam 15 can reciprocate to push the push-pull rod 16 to move up and down, so that the filter plate 17 shakes up and down to improve the screening efficiency of the straws larger than the crops in the crops;
the rotation of the rotating shaft 13 also drives the worm wheel 19 to rotate, so that the worm wheel 19 drives the rotating rod 20 to rotate, the rotation of the rotating rod 20 drives the cutter blade 23, the cutting wheel 24 and the conveying roller 25 to rotate, the straws entering the crushing cylinder 9 firstly fall on the position of the conveying roller 25, the cutter blade 23 primarily crushes the straws while conveying the straws, the conveying roller 25 conveys the crushed straws while crushing, the filter cylinder 28 filters the residual crops in the straws while conveying the conveying roller 25, so that only the primarily crushed straws in the crushing cylinder 9 enter the hopper 3 through the filter cylinder 28, the primarily crushed straws are further crushed by the cutter blade 23 and the cutting wheel 24 after being separated from the conveying roller 25, and in the process, due to the rotation of the conveying roller 25, the push rod 26 slides along one side of the push ring 27 far away from the collecting hopper 6, when the push rod 26 slides from the concave surface of the push ring 27 to the outside of the concave surface, the sliding frame 22 slides along the inner side wall of the sliding groove 21 and the outer side wall of the rotating rod 20 towards the direction of the collecting hopper 10, the conveying roller 25 and the cutting wheel 24 can push crushed straws into the collecting hopper 10, when the push rod 26 slides along the concave surface of the push ring 27 to the inside of the concave surface, the straws are discharged into a paddy field from the collecting hopper 10, the conveying roller 25 slides along the inner side wall of the sliding groove 21 and the outer side wall of the rotating rod 20 towards the direction of the collecting hopper 6 under the action of the push spring 29, the sliding frame 22 slides along the inner side wall of the sliding groove 21 and the outer side wall of the rotating rod 20 towards the direction of the collecting hopper 6, the crushed straws in the crushing cylinder 9 are reciprocally conveyed, the crushed straws in the crushing cylinder 9 are prevented from being accumulated to influence the crushing efficiency, at the moment, the straws entering the rice field are smaller due to crushing, so that the straws are more easily corroded and absorbed by the rice field, the corrosion efficiency of the rice field to the straws is improved, the root protecting effect of the rice field to sample roots of subsequent crops is ensured, in the process, the conveying roller 25 also scrapes the inner side wall of the filter cylinder 28, the discharge efficiency of the crops is prevented from being influenced by the condition that the inner side wall of the filter cylinder 28 is blocked, and the waste of the crops is caused;
until the collection of crops is completed or the hopper 3 is full of crops, the rear door 4 can be opened to discharge the crops when the hopper 3 is full of crops.
It should be noted that, the specific model specification of the motor 12 needs to be determined by selecting a model according to the actual specification of the device, and the specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
