The feeding roller 3-1-5 consists of a rotating shaft 3-1-5-1 driven by a hydraulic motor supported on a bearing seat 3-1-4 at the lower end of the rear suspension loop and a feeding stirring plate 3-1-5-2 which radially extends and is uniformly distributed in the circumferential direction. The diversion device comprises a horizontal cross frame 3-1-6 fixed at the lower end of the front hanging lug and a fluid director 3-1-7 fixed on the cross frame at intervals. The fluid director 3-1-7 is made by spring steel wire which is bent into a door shape vertically and then bent into a curved cantilever with a front low and a rear high smooth curve from the bottom end of the door shape, the upper edge of the door shape is hung in the elbow at the front end of the fixed plate 3-1-10, and the rear end of the fixed plate 3-1-10 is fixed on the horizontal cross frame 3-1-6. The bent structure of the fluid director 3-1-7 can play a role in elastically blocking and inhibiting the picked and thrown crops, so that the movement track of the crops can be restrained, and the crops are prevented from being thrown and scattered.
When the rape crop picking-up operation needs to be carried out in a hollow place, as shown in fig. 6 to 8, the front adjusting rod 3-1-8 and the rear adjusting rod 3-1-9 are hinged with each other through a hinged hole (if indeed needs, the hinged hole and the positioning hole can be fixedly connected through a fastener at the same time), the front adjusting rod 3-1-8 is in a forward-raised state, and a reverse-rotation feeding assembly 3-2 is arranged between the front adjusting rod 3-1-8 and the rear adjusting rod 3-1-9 on the two sides through a front suspension loop 3-1-3' and a rear suspension loop 3-1-3. The reverse-rotation feeding assembly 3-2 comprises a front roll shaft 3-2-6 and a rear roll shaft 3-2-5 which are respectively supported at the lower ends of a front hanging lug 3-1-3' and a rear hanging lug 3-1-3, feeding belts are wound on the front roll shaft 3-2-6 and the rear roll shaft 3-2-5, and the rear roll shaft 3-2-5 is driven by a hydraulic motor. The middle part of the feeding belt is a sawtooth stirring belt 3-2-7, and the two sides of the feeding belt are diversion feeding belts 3-2-10 with cross parting strips 3-2-11 distributed at intervals. The transmission direction of the feeding belt is opposite to that of the two-section type pick-up device 4. During operation, the self-weight descending trend of the front roller shaft of the front adjusting rod can keep the feeding belt in a natural tensioning state, the transverse division bars of the guide feeding belt play a role in increasing the conveying effect on crops, and the middle sawtooth-shaped stirring bar can avoid the accumulation of the crops on the belt surface caused by the high density of the crops in the middle. The sawtooth stirring bar and the like are made of PVC soft plates.
The multi-purpose crop pickup device of the embodiment originally creates two convenient and interchangeable auxiliary conveying and feeding devices respectively corresponding to different field conditions and rape states, namely when the ground of a field is flat and the rape laying consistency is good, a diversion feeding assembly with a crop deflector and a forced feeding device is adopted, the diversion effect at the front part can effectively prevent materials from being thrown away, the diversion effect on the materials is achieved, the materials cannot be blocked, the forced feeding device at the rear part can press the materials into an auger, and the situation that the feeding of the auger is not smooth and blocked due to overlarge flow is prevented; when the fields are poor in ground depression and rape laying consistency, or the rapes are tall, big, thick and many branches, the reverse rotation feeding assembly with the reverse rotation type diversion forced feeding device is adopted, continuous action can be generated on materials, the structure is compact, the movement is stable, and the linear speed can be kept within a certain range, so that continuous and stable auxiliary conveying action is generated on the materials, the pushing force generated by reverse rotation of the reverse rotation device is combined with the pushing force generated by the belt surface forward rotation of the pickup device, and the conveying efficiency can be effectively improved.
