Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paddy processing, in particular to a rice processing transfer equipment with anti-collision structure. BACKGROUND

[0002] Paddy processing refers to the process of removing paddy hulls (hull) and skin layers (bran layers). Paddy kernels are composed of hulls, skin layers, embryos and endosperms. The purpose of paddy processing is to separate the endosperms from other parts with the least degree of breakage to produce rice with good food quality.

[0003] In the processing factory, sometimes rice needs to be transferred. In order to reduce the number of transfers, a lengthened transfer cart is generally used to transfer a large amount of rice. Since the equipment in the factory is not on the same straight line, the transfer process may encounter a position where the direction needs to be changed. Since the lengthened transfer cart is difficult to control the speed and the operator is not convenient to observe the distance between the cart head and the corner wall, collisions between the cart and the wall often occur during transfer, which seriously affects the normal operation of the transfer cart. The traditional transfer vehicle lacks sufficient anti-collision structure to protect the transfer vehicle.

[0004] In the prior art, the Chinese invention with publication number CN108773402A discloses a transfer cart for agricultural product processing, which comprises a bottom plate, four corners of the bottom plate are fixedly provided with wheel seats, walking wheels are rotatably connected to the wheel seats, a storage basket is arranged above the bottom plate and parallel to the bottom plate, four corners of the top surface of the bottom plate are fixedly provided with connecting plates, the upper ends of the connecting plates are fixed to the bottom surface of the storage basket, a plurality of storage plates are further arranged below the storage basket, the storage plates are composed of non-woven fabric blocks and a plurality of strip-shaped plates, and the strip-shaped plates are uniformly and equidistantly bonded to the back surface of the non-woven fabric blocks. The invention solves the problem of limited utilization space of the current transfer cart and the inability to adjust as needed.

[0005] The above technical solution lacks a protection structure assembly for the storage basket. When the transfer cart collides with the wall or other objects during movement, since the transferred agricultural products are heavy, the inertia is large during turning, which is difficult to control, and the storage basket often collides with the wall, which not only easily causes damage to the cart, but also may cause the agricultural products to slide out of the storage basket.

The frame 6 is connected to the transfer carriage 1 via the connecting rod 5, the movable rod 3, and the transfer vehicle. When the transfer vehicle collides with the wall due to inertia while turning, the outer curvature of the movable frame 6 causes it to deflect, exerting a lateral guiding force on the transfer vehicle and converting part of the impact force into a deflecting force.
