Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste bamboo and wood recycling technology, and in particular relates to an automated recycling and reuse device for waste bamboo and wood. Background Technology
[0002] The automated recycling and reuse device for waste bamboo and wood belongs to the field of biomass waste treatment technology. It is mainly used to mechanically crush waste materials from bamboo product processing and waste bamboo materials from landscaping, and convert them into raw materials that can be used for organic fertilizer production, carbonized fuel preparation and other applications.
[0003] Existing automated recycling and reuse devices for waste bamboo and wood mainly consist of a shell, a crushing mechanism, and a discharge port. The shell guides the waste bamboo and wood, which is then crushed by the crushing mechanism and finally discharged through the discharge port. However, existing automated recycling and reuse devices for waste bamboo and wood have the following drawbacks in practical use:
[0004] First, existing automated recycling and reuse devices for waste bamboo and wood can only perform crushing operations and lack multi-stage separation mechanisms, resulting in uneven particle size and inability to classify the crushed material (smaller particles can be used for organic fertilizer production, but are often discharged mixed with larger particles, requiring additional manual sorting; larger particles are suitable for carbonization, but because they are not screened, their substandard particle size may affect subsequent carbonization efficiency); second, existing automated recycling and reuse devices for waste bamboo and wood cannot recycle waste bamboo and wood that does not meet the requirements, requiring manual collection and re-input, resulting in low production efficiency.
[0005] Therefore, it is essential to invent an automated recycling and reuse device for waste bamboo and wood. Utility Model Content
[0006] To address the above problems, this utility model proposes an automated recycling and reuse device for waste bamboo and wood. The technical solution used is as follows:

Two crushing shafts are rotatably mounted inside the upper end of the shell via support bearings, and the two crushing shafts are connected by gear meshing. A support frame is bolted to the outer side of the upper end of the shell, and a first motor is bolted to the outer side of the support frame. The output end of the first motor is fixed to one of the crushing shafts. A multi-stage separation mechanism is located below the crushing shafts and is fixed inside the shell. The multi-stage separation mechanism has several discharge ends, each of which is equipped with a discharge mechanism, all of which are fixed inside the shell. The discharge ends of the discharge mechanisms are located at corresponding discharge port positions, which are opened on the side of the shell.
[0008] Furthermore, the multi-stage separation mechanism includes a first belt conveyor, a second belt conveyor, a third belt conveyor, a first screening hole, a second screening hole, and a second motor.

The first belt conveyor is located below the crushing shaft, and the second belt conveyor is located below one end of the first belt conveyor, while the third belt conveyor is located below the end of the second belt conveyor away from the first belt conveyor. A plurality of first screening holes are evenly distributed on the belt of the second belt conveyor, and a plurality of second screening holes are evenly distributed on the belt of the third belt conveyor, wherein the diameter of the second screening holes is larger than the diameter of the first screening holes. A discharge mechanism moves through the middle of the belts of the second and third belt conveyors. This arrangement allows for the screening of waste bamboo and wood that has been crushed by the crushing shaft and its conveyor to the corresponding discharge mechanism.
[0009] Furthermore, the discharge mechanism includes a fourth belt conveyor and a third motor. The fourth belt conveyor is movably disposed inside the second or third belt conveyor, and the frame of the fourth belt conveyor is fixed to the outer casing with bolts. One end of the fourth belt conveyor is located at the corresponding discharge port. The corresponding drive shaft of the fourth belt conveyor is fixed to the output end of the third motor, and the base of the third motor is fixed to the outer casing with bolts. This arrangement enables the waste bamboo and wood discharged from the second and third belt conveyors to be transported to the discharge port.
[0010] Furthermore, a fifth belt conveyor is provided below the third belt conveyor, wherein the frame of the fifth belt conveyor is fixed to the outer casing by bolts, and the corresponding drive shaft of the fifth belt conveyor is fixed to the output end of the fourth motor, the base of the fourth motor being fixed to the outer casing by bolts; a protective shell is provided on the side of the fifth belt conveyor away from the third belt conveyor, wherein at least one screw shaft is rotatably mounted inside the protective shell via a support bearing; the fifth motor is fixed to the upper end of the protective shell by bolts, wherein the output end of the fifth motor is fixed to the screw shaft; the height of the protective shell is greater than the height of the outer casing, and this arrangement allows for the recycling of waste bamboo and wood that does not meet the pulverization requirements.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The present invention, through the cooperation of the crushing shaft and the first motor, can crush waste bamboo and wood. Then, through a multi-stage separation mechanism, the crushed waste bamboo and wood is screened (smaller pieces can be used to make organic fertilizer, biomass compost, or animal bedding, while larger pieces are used for subsequent carbonization and as fuel). The crushed waste bamboo and wood is then conveyed to the corresponding discharge mechanism and discharged at the discharge port. In addition, through the fifth belt conveyor, the fourth motor, the protective shell, the screw shaft, and the fifth motor, waste bamboo and wood that does not meet the crushing requirements can be returned and crushed again by the crushing shaft, thus ensuring that the waste bamboo and wood is thoroughly crushed.
