AI Technical Summary
In existing technologies, grain storage facilities face problems such as environmental pollution from manual cleaning, high manpower costs, and financial expenditure on purchasing woven bags during the collection and transportation of screened materials.
Industrial vacuum cleaners are used to collect screened materials, which are then poured into grain trucks via a side-mounted material bin lifting and tilting mechanism. This reduces manual operation and the use of woven bags, and the operation is automated by using a handcart and the lifting and tilting mechanism.
This reduces manual labor, avoids dust pollution, lowers costs, and improves the automation level of undersize material processing.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of equipment for grain warehouses, specifically to a grain warehouse undersize processing device. Background Technology
[0002] When grain is purchased and stored at grain reserves, the delivery person typically uses bulk grain trucks to transport the grain into the reserve. The raw grain and truck weight are measured on a weighbridge. The grain reserve then sieves the raw grain to remove impurities, resulting in clean grain for storage. The screened material (including chaff, dust, bran, straw, etc.) is then loaded into the grain truck. Finally, the screened material and truck weight are measured on a weighbridge to obtain the clean grain weight, which is used for financial settlement. Currently, grain reserves typically handle the screened material by manually sweeping it and packing it into woven bags purchased by the reserve. These bags are then loaded into the grain truck. This method of handling screened material involves manual sweeping and bagging, generating dust, which not only pollutes the environment and wastes manpower but also incurs significant annual costs for purchasing woven bags. Summary of the Invention
[0003] To address the problems encountered in the collection and transportation of screened material during grain storage in the background art, this utility model proposes a grain storage screened material processing device.
[0004] The present invention discloses a grain depot undersize material processing device, comprising an undersize material collection device and an undersize material loading device; the undersize material collection device is an industrial vacuum cleaner fixedly mounted on a first handcart, and the dust collection bucket of the industrial vacuum cleaner has an outward-facing skirt along its opening; the undersize material loading device is a side-mounted material bucket lifting and tilting mechanism fixedly mounted on a second handcart (this mechanism is prior art and will not be described in detail in this patent), the material bucket fixing structure of the material bucket lifting and tilting mechanism is adapted to the dust collection bucket; the height of the track frame of the material bucket lifting and tilting mechanism is adapted to the grain transport vehicle with the highest compartment.
[0005] The track frame is equipped with hooks for attaching to the side panels of the grain truck's cargo compartment. Each hook is fixedly connected to a hook slider, which is positioned within a hook rail located on the outer side of the track frame. A fixed pulley is mounted on the track frame above the hook rail, and a traction rope, passing over the fixed pulley, is attached to the hook for lifting it. The hooks are attached to the side panels of the grain truck's cargo compartment to prevent the second handcart from slipping during operation.
[0006] Both the first and second handcarts are equipped with portable power banks.
[0007] The bottom surface of the dust collection bin is equipped with dust collection bin wheels to facilitate the movement of the dust collection bin.
[0008] The wheels of the second handcart are equipped with braking mechanisms to prevent the cart from slipping during operation.
[0009] The side of the second trolley is connected through a hinge for forming a steel plate of a slope, the dust collecting barrel forms an upper slope through the opened steel plate to push the dust collecting barrel from the ground to the trolley plate, and the steel plate is lifted and placed on the trolley plate after the work is completed.
[0010] The grain storehouse sieve under material processing device in the utility model collects the sieve under material in the dust collecting barrel through the industrial dust collector in use, reduces the manual labor, and avoids dust pollution; then the sieve under material in the dust collecting barrel is poured into the grain transport vehicle compartment through the side-mounted material barrel lifting and overturning mechanism located on the second trolley, a woven bag does not need to be purchased any more, cost expenditure is reduced, and the device is beneficial to popularization and application in the grain reserve storehouse.
