Description

Technical Field

[0001] This utility model relates to the field of material recycling technology, specifically to a recycling vehicle for iron filings, iron powder, and steel shot. Background Technology

[0002] In steel structure manufacturing plants, one of the most important processes is the anti-corrosion treatment of steel plates or components. This involves surface rust removal followed by painting. The primary equipment used in the rust removal process is a shot blasting machine. The shot blasting machine works by using a high-speed rotating motor to propel steel shot at high speed through blades. The steel shot impacts the steel plate at a speed of 70-90 meters per second, achieving the purpose of removing rust from the steel surface. Therefore, in actual operation, a considerable amount of steel shot is ejected from the inlet and outlet of the shot blasting machine, flying onto the ground around the machine and scattering over a large area, resulting in significant waste.

[0003] In addition, during the workshop processing, a large amount of scrap iron is generated due to cutting, forging, punching, and other processes. This scrap is usually in the form of flakes or powder, contains a large amount of impurities and iron oxide, and is of uneven quality. It is generally scattered on the workshop floor. If manual cleaning is used, the collected iron filings and powder will contain a lot of dust and garbage, and screening and separation will be required. Relying on manual cleaning and separation is not only inefficient, but also very labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a recycling vehicle for iron filings, iron powder, and steel shot. It can achieve magnetic adsorption of iron filings, iron powder, and steel shot. At the same time, the bottom plate isolation and the rotating cover plate facilitate the separation of the adsorbed iron filings and iron powder from the strong magnetic block at the bottom of the cover plate, making recycling and separation convenient.

[0005] This utility model is achieved through the following technical solution:

[0006] A recycling vehicle for iron filings, iron powder, and steel shot is provided, comprising a frame base and a handrail frame. Mounting plates are horizontally connected to the front and rear of the frame base, and each mounting plate has an inverted U-shaped wheel frame mounted on its bottom surface via a lifting mechanism, with rollers rotatably mounted at both ends of the wheel frame. The handrail frame is inclined, with its lower end fixed to the rear end of the frame base and two handrails at its upper end. An operating lever is also hinged to the handrail frame. A non-magnetic base plate is connected to the bottom opening of the frame base, and a cover plate rotatably mounted to the handrail frame is provided at the top opening of the frame base. A pull rod is hinged between the cover plate and the middle of the operating lever, and strong magnetic blocks are evenly distributed on the bottom surface of the cover plate.

[0007] This solution designs a frame base, using a non-magnetic partition at the bottom of the base to isolate the strong magnet at the bottom of the cover plate from the ferrous items such as iron filings to be adsorbed. By pushing the handrail, the frame base can be moved, allowing the strong magnetic attraction of the strong magnet to adsorb iron filings, steel shot, etc., from the workshop floor. After adsorption, the operating lever can be used to rotate the pull rod, which in turn rotates the fixed shaft, causing the cover plate to rotate upwards, forcibly separating the strong magnetic block from the adsorbed material. This facilitates the separation of the adsorbed iron filings and steel shot, improving the convenience of recycling.

[0008] Furthermore, the surface of the cover plate is inclinedly connected to two support rods on both sides of the rear end of the hinged tie rod, and a fixed shaft is rotatably mounted on the handrail frame, with both ends of the fixed shaft connected to the support rods respectively.

[0009] A support rod is provided at the rear end of the cover plate, and the support rod is connected to a fixed shaft on the handrail frame. The cover plate can be separated from and brought closer to the frame base by rotating the fixed shaft, which can be used to separate the adsorbed iron pins.

[0010] Furthermore, the lifting mechanism includes a fixed support column, a lifting sleeve, and a battery pack. The fixed support column is vertically fixed in the middle of the wheel frame, and the lifting sleeve is vertically fixed on the bottom surface of the mounting plate and directly opposite the lifting sleeve. The battery pack is mounted on the surface of the mounting plate. The fixed support column has a cavity inside, and a fixing nut is snapped and fixed at the top of the cavity. A lead screw that penetrates the end face of the fixed support column is vertically threaded through the center of the fixing nut. The lifting sleeve is divided into an installation cavity and a sliding cavity by a partition. The upper end of the lead screw penetrates the partition and is connected to a worm gear in the installation cavity. The sliding cavity of the lifting sleeve is fitted outside the fixed support column and slides with the fixed support column. A worm that mates with the worm gear is horizontally mounted above the lead screw in the installation cavity of the lifting sleeve. One end of the worm penetrates the installation cavity and is connected to a rotating gear. A drive motor that is electrically connected to the battery pack is also mounted on the bottom surface of the mounting plate. A drive gear that meshes with the rotating gear is mounted on the drive shaft of the drive motor.

[0011] The drive motor drives the rotating gear, which in turn drives the worm gear transmission to drive the lead screw to rotate. The lead screw rotates within the fixed nut. With the limiting action of the lifting sleeve and the fixed support, the rotation of the lead screw drives the lifting sleeve to move up and down on the fixed support, which in turn drives the wheel frame to move up and down. This allows the frame base to be raised and lowered, making it easy to adjust the height of the frame base according to the terrain to ensure the adsorption effect.

[0012] Furthermore, a control switch is installed on the side of each handle. The control switch is electrically connected to the drive motor and is used to control the forward and reverse rotation of the drive motor.

[0013] Each handle has a control switch installed on its side. The two handles control the front and rear drive motors respectively. The height of the front and rear sides can be adjusted by controlling the forward and reverse rotation of the drive motors according to the flatness of the actual workshop floor. It can be used to adapt to different terrains. After the adsorption operation is completed, the height of the frame base can be raised to facilitate pushing the recycling vehicle to the recycling point and placing the recycling container at its bottom for easy recycling and unloading.

[0014] Furthermore, guide posts are vertically connected to both sides of the wheel frame on the fixed post, and guide through holes are opened on the mounting plate corresponding to the guide posts.

[0015] The wheel frame is vertically connected to guide columns on both sides of the fixed column. Together with the guide through holes on the mounting plate, it can play a guiding and limiting role when the wheel frame drives the frame base to rise and fall, ensuring the stability of the rise and fall.

[0016] Furthermore, the bottom open end of the frame base is bent inward in all directions to form an inner folded edge, and the non-magnetic base plate is fixed on the inner folded edge.

[0017] The bottom circumference of the frame base is bent inward to form an inner folded edge, which can be used to support the base plate and the upper cover plate. It also facilitates the connection of the base plate. The non-magnetic base plate can isolate the adsorbed iron debris from the strong magnetic block, so that the scrap iron debris can be separated from the strong magnetic block when the cover plate is rotated.

[0018] The beneficial effects of this utility model are:

[0019] This invention allows for the manual movement of a frame base on the workshop floor via a handrail, which, in conjunction with a strong magnetic block at the bottom of the cover plate, attracts and adsorbs iron filings, steel shot, and iron powder from the ground. Once the non-magnetic partition is full, a manual control lever can be used to pull a rotating rod. This rotation causes a fixed shaft to rotate, which in turn rotates the cover plate counterclockwise, moving it upwards away from the frame base. Combined with the separation effect of the non-magnetic partition, this forcibly separates the strong magnetic block from the adsorbed material, facilitating its recycling and collection. The operation is simple and convenient, with high efficiency in separation and recycling after adsorption. It solves the problem of employees struggling to clean up scattered steel shot, iron filings, and iron powder from the ground, reducing labor intensity and improving work efficiency.

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figure 1 As shown, a recycling vehicle for iron filings, iron powder, and steel shot includes a frame base 1 and a handrail frame 2. Mounting plates 4 are horizontally connected to the front and rear of the frame base 1, respectively. Each mounting plate 4 has an inverted U-shaped wheel frame 18 mounted on its bottom surface via a lifting mechanism, and rollers 5 are rotatably mounted at both ends of the wheel frame 18. The handrail frame 2 is inclined, and its lower end is fixed to the rear end of the frame base 1. In this embodiment, as shown... Figure 3 As shown, the handrail frame 2 includes two parallel fixed rods 13 of the same length. Each fixed rod 13 has a handrail 3 for gripping on its upper part. A connecting rod 14 is vertically connected between the upper parts of the two fixed rods 13. Two reinforcing rods 15, parallel to the fixed rods 13, are connected between the middle of the connecting rod 14 and the rear end of the frame base 1. An operating rod 6 is hinged between the reinforcing rods 15. The bottom open end of the frame base 1 is bent inwards circumferentially to form an inner folded edge 16, and a non-magnetic base plate 17 is fixed to the inner folded edge 16. To reduce costs, in this embodiment, the fixed rods 13 are round tubes, and the reinforcing rods 15 and connecting rods 14 are square tubes, and the entire assembly is connected and fixed by welding.

[0029] A cover plate 8, rotatably mounted to the handrail frame 2, is provided at the top opening of the frame base 1. Two support rods 10 are obliquely connected to the rear ends of the hinged tie rod 7 on the surface of the cover plate 8. A fixed shaft 11, passing through a reinforcing rod 15, is laterally rotatably mounted on the handrail frame 2 between two fixed rods 13. Both ends of the fixed shaft 11 are connected to the support rods 10. A tie rod 7 is hinged between the cover plate 8 and the middle of the operating rod 6. Strong magnetic blocks 12 are evenly distributed on the bottom surface of the cover plate 8. The strong magnetic blocks 12 have a split structure, consisting of 24 strong magnets assembled as a whole.

[0030] like Figure 5 As shown, the lifting mechanism includes a fixed support column 20, a lifting sleeve 21, and a battery pack 31. The fixed support column 20 is vertically fixed to the middle of the wheel frame 18, and the lifting sleeve 21 is vertically fixed to the bottom surface of the mounting plate 4 and directly opposite it. Guide columns 19 are vertically connected to both sides of the fixed support column 20 on the wheel frame 18, and guide through holes are opened on the mounting plate 4 corresponding to the guide columns 19. In order to ensure rotation limit, the cross-sections of the fixed support column 20 and the lifting sleeve 21 are non-circular polygons, generally rectangular.

[0031] The battery pack 31 is mounted on the surface of the mounting plate 4. A cavity 22 is provided inside the fixed support column 20. A fixing nut 23 is snapped and fixed to the top of the cavity 22. A lead screw 24, penetrating the end face of the fixed support column 20, is vertically threaded through the center of the fixing nut 23. The lifting sleeve 21 is divided into an installation cavity and a sliding cavity by a partition 25. The upper end of the lead screw 24 penetrates the partition 25 and is connected to a worm gear 27 within the installation cavity. The lead screw 24 is fixed relative to the partition 25. The lead screw 24 rotates and rises within the fixing nut 23. The partition 25 and the lifting sleeve 21 are raised and lowered synchronously. The sliding cavity of the lifting sleeve 21 is sleeved outside the fixed support 20 and slides in cooperation with the fixed support 20. The worm 26 that cooperates with the worm wheel 27 is installed horizontally above the lead screw 24 in the mounting cavity of the lifting sleeve 21. One end of the worm 26 passes through the mounting cavity and is connected to the rotating gear 29. The bottom surface of the mounting plate 4 is also equipped with a drive motor 28 that is electrically connected to the battery pack 31. The drive shaft of the drive motor 28 is equipped with a drive gear 30 that meshes with the rotating gear 29.

[0032] Each handle 3 has a control switch 9 mounted on its side. The control switch 9 is electrically connected to the drive motor 28 and is used to control the forward and reverse rotation of the drive motor 28. One handle is used to control the forward and reverse rotation of the front drive motor, and the control switch on the other handle is used to control the forward and reverse rotation of the rear drive motor.

[0033] The working process of this utility model:

[0034] Workers can move the frame base 1 and rollers 5 across the workshop floor by holding the handrail 3 and using the handrail frame 2. When passing over iron-containing waste, the strong magnetic block 12 at the bottom of the cover plate 8 uses magnetic force to attract iron filings, iron chips, and steel shot onto the non-magnetic base plate 17. By continuously walking and covering the workshop area, iron-containing waste on the ground can be concentrated and attracted onto the non-magnetic base plate 17. When encountering uneven terrain, the control switch 9 on the side of the handrail 3 can control the front or rear drive motor 28 respectively, using the drive... The motor 28 drives the worm gear 26 to rotate, which in turn drives the worm wheel 27 to rotate, which in turn drives the lead screw 24 to rotate within the fixed nut 23. Under the rotational limiting action of the fixed support column 20 and the lifting sleeve 21, the lifting sleeve 21 and the fixed support column 20 can move up and down, thereby raising and lowering the wheel frame 18 and driving the frame base 1 to rise and fall, so as to meet the needs of different terrain heights. After the adsorption on the workshop floor is completed, by manually pulling the operating lever 6 upward, the operating lever 6 drives the pull rod 7 to rotate, and the pull rod 7 drives the cover plate 8 to rotate counterclockwise. Figure 2 As shown, this allows the strong magnetic block 12 on the cover plate 8 to be moved away from the non-magnetic base plate 17, thereby facilitating the forced separation of the strong magnet 12 from the adsorbed iron-containing waste, and thus facilitating the separation and recycling of the adsorbed waste. By raising the height of the frame base 1, it is convenient to place the recycling box on the non-magnetic base plate 17 for easy material collection during separation.
