[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-3 This application provides a technical solution for a molding sand removal and recycling device for tractor gearbox body production: A molding sand removal and recycling device for tractor gearbox body production includes a processing box 1 and a conveyor roller 2. The processing box 1 has an inlet and outlet 3 from left to right, and a dustproof cloth 4 is installed inside the inlet and outlet 3. The conveyor roller 2 is installed inside the processing box 1.

[0020] Specifically, the dustproof cloth 4 prevents the molding sand from being blown out of the processing box 1, thus facilitating the collection of the molding sand. The conveyor roller 2 smoothly feeds the gearbox body into the processing box 1, ensuring uniform removal of the molding sand and improving work efficiency.

[0021] The two ends of the inlet and outlet 3 on the processing box 1 are connected to the external conveyor belt, which facilitates continuous transmission of the gearbox body and improves the efficiency of molding sand removal and recycling.

[0022] The treatment box 1 is equipped with a connecting air pipe 5. The top end of the connecting air pipe 5 passes through the treatment box 1 and is connected to the installation air pipe 6. An air gun 7 is installed at the bottom end of the connecting air pipe 5. A round hole 8 is provided on the front side of the treatment box 1. A rubber glove 9 is installed inside the round hole 8. An observation window 10 is opened on the sloping front side of the treatment box 1.

[0023] Specifically, the air hose 6 is connected to an external compressed air pipeline. The air gun 7 can spray high-pressure air to remove residual molding sand on the housing. The rubber gloves 9 can protect the worker and facilitate the worker's operation of the air gun 7 and the housing. The operator can visually monitor the molding sand removal progress through the observation window 10 and adjust the air pressure and angle of the air gun 7 in a timely manner to ensure effective removal of molding sand.

[0024] Furthermore, a worktable 24 is provided in the middle of the conveyor roller 2. A top plate is rotatably connected to the bottom of the worktable 24. The top plate is connected to the telescopic end of the lifting cylinder 25. The lifting cylinder 25 is fixed inside the processing box 1 by a connecting plate.

[0025] Specifically, the workbench 24 facilitates the placement and fixing of the gearbox body. With the extension and retraction of the lifting cylinder 25, the gearbox body can move up and down automatically, making it easier for workers to clean the gearbox. At the same time, the rotating connection of the bottom top plate of the workbench 24 allows the workbench 24 to be rotated by hand after the lifting cylinder 25 lifts it up, thus facilitating a comprehensive inspection of the gearbox and removal of molding sand.

[0026] Furthermore, an installation frame is fitted around the outside of the workbench 24, and auxiliary transmission rollers 26 are provided between the front and rear ends of the installation frame and the processing box 1. The auxiliary transmission rollers 26 work together with the conveying rollers 2 to improve the conveying stability of the gearbox body.

[0027] A guide bucket 11 is provided below the conveyor roller 2, and a crushing group 12 is provided at the discharge position of the guide bucket 11.

[0028] Furthermore, the crushing unit 12 includes crushing rollers 13, crushing motors 14, and mounting plates 15. Two crushing rollers 13 are arranged below the discharge position of the guide bucket 11. The two ends of the crushing rollers 13 are rotatably connected to the mounting plates 15. One of the mounting plates 15 is connected to the crushing motor 14 through a motor mounting seat, and the power output shaft of the crushing motor 14 is connected to the crushing rollers 13.

[0029] Specifically, when the removed molding sand falls into the guide hopper 11, it is further crushed by the rotation of the crushing roller 13 and the drive of the crushing motor 14, thereby improving the molding sand recovery efficiency. After being processed by the crushing group 12, the molding sand is filtered by the filtration group 16.

[0030] Below the crushing group 12 is a filter group 16, which includes a filter screen 17, a vibration motor 18, a flexible limiting group 19, a support block 20, and a limiting support plate 21. The vibration motor 18 is located below the filter screen 17. Two flexible limiting groups 19 are respectively provided on both sides of the lower surface of the filter screen 17. The two lower flexible limiting groups 19 are slidably connected to the support block 20, and the support block 20 is fixed to the inner wall of the processing box 1. The other two flexible limiting groups 19 are slidably connected to the limiting support plate 21, and the limiting support plate 21 is fixed to the guide bucket 11.

[0031] Specifically, through the combined operation of filter screen 17 and vibration motor 18, molding sand is effectively filtered, impurities are separated, and pure molding sand is recycled, improving the efficiency and environmental friendliness of the entire process. Meanwhile, flexible limiting group 19 can limit the filter screen 17, thereby improving the filtration stability of filter screen 17.

[0032] Furthermore, the flexible limiting assembly 19 includes a guide rod 22 and a spring 23. The guide rod 22 is disposed on the lower surface of the filter screen 17, and the spring 23 is sleeved on the outside of the guide rod 22.

[0033] The support block 20 and the limiting support plate 21 have guide holes at the corresponding guide rods 22, and the guide rods 22 are inserted into the guide holes of the support block 20 and the limiting support plate 21.

[0034] Furthermore, a material receiving drawer is provided at the bottom of the processing box 1, and a waste collection box is provided on one side of the processing box 1, with the waste collection box located on the lowest side of the filter group 16.

[0035] Specifically, by setting up receiving drawers and waste collection bins, waste and finished products after molding sand processing are collected separately, which facilitates classification, processing and reuse.

[0036] In use: The gearbox body to be processed is transported by an external conveyor belt and transported into the processing box 1 through the inlet / outlet 3 at one end of the processing box 1. It is then transported to the top of the worktable 24 by the conveyor roller 2. The lifting cylinder 25 drives the top plate and the worktable 24 to move upward, lifting the gearbox body. Then, the worker puts both hands into rubber gloves 9, one hand operates the air gun 7 to blow away the residual molding sand on the gearbox body, and the other hand stabilizes the gearbox body to ensure that the molding sand is completely removed. Alternatively, the worktable 24 can be rotated to make the gearbox body rotate so as to remove the molding sand from all angles and ensure that there are no sand particles left on the surface of the gearbox body. After cleaning, the lifting cylinder 25 drives the worktable 24 to reset, and the auxiliary drive roller 26 and the conveyor roller 2 work together to remove the gearbox body from the processing box 1.

[0037] The removed molding sand falls onto the crushing unit 12 through the guide bucket 11. Two crushing motors 14 drive two crushing rollers 13 to rotate relative to each other, thereby crushing the blocky molding sand and making it finer for subsequent filtration. The crushed molding sand enters the filter screen 17, which is vibrated by the vibration motor 18, thereby filtering the molding sand. Larger molding sand flows through the filter screen 17 into the waste collection box, while qualified molding sand falls into the collection drawer at the bottom of the filter screen 17.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
