Description

Technical Field

[0001] This application relates to the technical field of straw processing, and in particular to a straw dust recovery device for straw processing. Background Technology

[0002] Straw is the remaining stalk of crops such as rice straw, wheat straw, and corn straw after harvest. It can be used as livestock feed, in papermaking, wood-based panel production, fermentation for fuel ethanol production, or as agricultural fertilizer to improve soil structure. During straw processing, the straw may contain sand and dust. To improve the processing quality, straw dust recovery devices are needed to treat the dust.

[0003] In related technologies, straw processing requires the use of straw dust recovery devices to treat the generated dust. Some existing straw dust recovery devices consist of a vibrating box and a vibrating screen. The vibrating box restricts the installation position of the vibrating screen. The operator places the straw to be processed on the vibrating screen, and the reciprocating linear motion of the vibrating screen shakes the dust attached to the surface of the straw into the dust collection box for collection. After the dust on the straw is cleaned, the operator can remove the processed straw by disassembling the side wall of the vibrating box. However, when there is a large amount of straw to be processed, the operator needs to repeatedly perform the feeding and unloading operations, which may increase the labor intensity of the personnel and may also affect the efficiency of straw dust recovery.

[0004] Therefore, those skilled in the art have provided a straw dust recovery device for straw processing to solve the problems mentioned in the background art. Utility Model Content

When the drive assembly 2 is started, it can cooperate with the multiple conveying rollers 3 to control the operation of the conveyor belt 4. The operation of the conveyor belt 4 can transport straw, and simultaneously, the vibrating plate 15 can be activated. The vibrating plate 15 can control the conveyor belt 4 to generate a certain vibration. The vibration of the conveyor belt 4 can shake off some of the dust on the straw.

[0045] In use, the straw to be processed is placed on the conveyor belt 4 inside the straw processing box 1. The drive assembly 2 is started and multiple conveyor rollers 3 work together to control the conveyor belt 4 to transport the straw. At the same time, the vibrating plate 15 is started to control the conveyor belt 4 to generate a certain vibration. The vibration of the conveyor belt 4 can shake off some of the dust on the straw. The continuous operation of the conveyor belt 4 can then transport the processed straw outward, thereby saving the operation steps of manual material handling, reducing the labor intensity of personnel, and improving the recycling efficiency of straw dust.

[0046] A V-shaped guide plate 5 is installed inside the straw processing box 1. Dust shaken off the straw can fall directly into the V-shaped guide plate 5. The dust is then transported into the waste collection box 7 through the connecting pipe 6, so that personnel can collect the dust centrally. An exhaust fan 8 is installed inside the waste collection box 7. When the exhaust fan 8 is started, the dust extraction hood 12 can be controlled through the dust extraction pipe 11 to perform suction. After the air with floating dust is sucked into the waste collection box 7, it can be filtered by the filter plate 9 to prevent the dust from being discharged to the outside of the rectangular box 701 along with the exhaust fan 8. This can further reduce the dust on the straw and improve the quality of the straw.
