Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and specifically to a foldable conveyor belt. Background Technology

[0002] Conveyor belts are widely used in agriculture, industry, mining and transportation to transport various solid lumps and powders or packaged goods. Conveyor belts enable continuous and efficient transportation, are safe to operate, easy to use and maintain, have low transportation costs, and can shorten transportation distances, reduce project costs, and save manpower and resources.

[0003] Existing conveyor belts occupy a large area and are inconvenient for transportation, especially for the transmission belts used when loading grain onto transport vehicles. According to the needs, the conveyor belt is placed in a suitable location. During the process of transporting grain by conveyor belt, since the unloading point on the transmission belt is fixed and the unloading direction cannot be adjusted, the grain must be discharged along the length of the conveyor belt, which easily leads to the accumulation of grain in the transport vehicle's bucket. It is necessary to manually use tools to push it to one side and spread it evenly in the bucket, or to constantly adjust the position of the bucket or conveyor belt to change the position of the grain unloading port to meet the feeding needs. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a foldable conveyor belt that not only facilitates transportation but also allows for changes in the orientation and length of the discharge port.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a foldable conveyor belt, comprising a first frame, a second frame, a lifting assembly, and a feeding assembly. One end of the first frame and one end of the second frame are hinged together, and when unfolded, they are limited by connecting pieces and bolts. An H-shaped support leg is provided below the other end of the second frame. The lifting assembly is mounted on the H-shaped support leg, and the feeding assembly is located on one side of the lifting assembly. The feeding assembly includes a feeding hopper and a discharge pipe located at the bottom of the feeding hopper. A guide pipe is rotatably mounted on the discharge pipe via a connecting seat. A telescopic pipe is fitted on the guide pipe. Both ends of the telescopic pipe are connected to limit plates, and an electric telescopic rod and several telescopic rods are provided between the limit plates.

[0006] Furthermore, the other end of the first frame is provided with a drive roller, the other end of the second frame is provided with a driven roller, a conveyor belt is wound between the driven roller and the drive roller, and several roller shafts are provided on the first frame and the second frame.

[0007] Furthermore, the lifting assembly includes a fixed rod and a movable support leg fitted onto an H-shaped support leg. One end of the fixed rod is fixed to the middle of the H-shaped support leg, and a pulley is installed at the other end of the fixed rod. One end of the movable support leg is hinged to the bottom of the second frame. A fixed frame is provided on the H-shaped support leg. A winding roller and a drive gear are rotatably installed inside the fixed frame. A rope is wound on the winding roller. One end of the rope is wound around the pulley and connected to the movable support leg through a hook. The end of the winding roller is connected to a driven gear that meshes with the drive gear. A handle is provided on the outside of the fixed frame. The handle is connected to the drive gear through a connecting plate.

[0008] Furthermore, the fixed frame has several limiting holes with the drive gear as the center, and the connecting plate is threaded with bolts. When the bolts extend out, they are inserted into the limiting holes to limit the handle.

[0009] Furthermore, the second frame is provided with a reinforcing rod, the other end of which is connected to the movable support leg.

[0010] Furthermore, both the lower end of the first frame and the lower end of the H-shaped support leg are equipped with casters.

[0011] Furthermore, a connecting ring is provided on the outer wall of the discharge pipe, and several balls are provided on both the upper and lower end faces of the connecting ring. A groove is provided in the connecting seat, and the connecting ring and the balls are both set in the groove.

[0012] Furthermore, the feed pipe includes a straight pipe and a bent pipe, the straight pipe is connected to the connecting seat through a flange, and the telescopic pipe is fitted onto the bent pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the first and second frames enable the conveyor belt to be folded, resulting in a smaller space occupied after folding, which facilitates storage and transportation; the movable support legs, fixed frame, winding roller, rope, and handle allow the conveyor belt's transport height to be adjusted according to the height of the truck bed, improving practicality; the combined use of the discharge pipe, guide pipe, connecting seat, and telescopic pipe allows the connecting seat to be rotated to change the orientation of the discharge port, and the electric telescopic rod to be activated to change the length of the telescopic pipe, thereby changing the discharge position of the discharge port, preventing material accumulation below the discharge port and affecting the conveying effect, while reducing the need for adjustments to the overall position of the transport truck bed and conveyor belt, thus improving loading efficiency.

[0020] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-5As shown, this utility model provides a foldable conveyor belt, including a first frame 1, a second frame 2, a lifting assembly 3, and a feeding assembly 4. The top of the first frame 1 and the top of the second frame 2 are hinged together. Connecting pieces are provided at the bottom of both the first frame 1 and the second frame 2, and these connecting pieces are connected by bolts. A drive roller 5 is provided at the end of the first frame 1 away from the second frame 2. A motor for driving the drive roller 5 is provided on one side of the first frame 1. A driven roller 6 is provided at the end of the second frame 2 away from the first frame 1. A conveyor belt 7 is wound between the driven roller 6 and the drive roller 5. Several roller shafts 8 are provided on both the first frame 1 and the second frame 2 along the material conveying direction. Support rollers are provided below both the first frame 1 and the second frame 2. An H-shaped support leg 9 is provided below the end of the second frame 2 away from the first frame 1. The lifting assembly 4 is mounted on the H-shaped support leg 9, and the unloading assembly 4 is mounted on one side of the lifting assembly 3. The unloading assembly 4 includes a hopper 401 and a discharge pipe 402 located at the bottom of the hopper 401. The hopper 401 is detachably mounted on the end of the second frame 2 via bolts through a mounting bracket. A guide pipe 404 is rotatably mounted on the discharge pipe 402 via a connecting seat 403. A telescopic pipe 405 is fitted onto the guide pipe 404. Both ends of the telescopic pipe 405 are connected to limit plates 406. The limit plate 406 near the hopper 401 is fixedly mounted on the guide pipe 404. An electric telescopic rod 407 and several telescopic rods 408 are provided between the limit plates 406. The telescopic rods 408 serve as guides and supports, preventing the telescopic pipe 405 from bending during use and causing difficulties in unloading.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, when unfolded, the conveyor belt 7 unfolds, the first frame 1 and the second frame 2 are on the same horizontal plane, and the connecting pieces on the first frame 1 and the second frame 2 are fixed by bolts. When not in use, the bolts can be removed, and the first frame 1 and the second frame 2 can be folded up. When the conveyor belt is inconvenient to move, the material conveying direction can be changed by changing the orientation of the guide pipe 404. After the material on the conveyor belt 7 enters the discharge hopper 401, it is discharged along the guide pipe 404 and the telescopic pipe 405. The telescopic pipe 405 is unfolded by the electric telescopic rod 407 and extended to the designated position, which makes it easy to place the material in the designated position. By rotating the guide pipe 404, the orientation of the discharge port can be changed, which can prevent the material from accumulating in the same place.

[0023] The lifting assembly 3 includes a fixed rod 301 and a movable support leg 302 fitted onto an H-shaped support leg 9. A square steel bar is fixedly connected to the movable support leg 302. The fixed rod 301 is slidably installed inside the square steel bar. One end of the fixed rod 301 is fixedly connected to the middle of the H-shaped support leg 9, and a pulley 303 is installed at the other end of the fixed rod 301. One end of the movable support leg 302 is hinged to the bottom of the second frame 2. When not in use, the movable support leg 302 can be folded up for easy transportation. A fixing frame 30 is fixedly connected to the H-shaped support leg 9. 4. A winding roller 305 and a drive gear 306 are rotatably mounted inside the fixed frame 304. The drive gear 306 is rotatably mounted inside the fixed frame 304 via a rotating shaft. A rope 307 is wound on the winding roller 305. One end of the rope 307 is wound around a pulley 303 and connected to the movable support leg 302 via a hook. The end of the winding roller 305 is connected to a driven gear 308 that meshes with the drive gear 306. A handle 309 is provided on the outside of the fixed frame 304. The handle 309 is connected to the rotating shaft via a connecting plate 310.

[0024] like Figure 3 As shown, by shaking the handle 309, the driving gear 306 is driven to rotate, and the driving gear 306 drives the driven gear 308 to rotate, thereby causing the winding roller 305 to rotate. The winding roller 305 drives the rope 307 to pull the movable support leg 302 upward under the action of the roller 303, thereby achieving the purpose of raising one end of the second frame 2 and changing the height of the discharge port.

[0025] The fixed frame 304 has several limiting holes 311 with the drive gear 306 as the center. The connecting plate 310 is threaded with bolts 312. When the bolts 312 extend out, they are inserted into the limiting holes 311 to limit the handle 309.

[0026] like Figure 3 As shown, when the second frame 2 is raised to a certain height by shaking the handle 309, the handle 309 is locked by inserting the bolt 312 into the limiting hole 311 to prevent the handle 309 from rotating in the opposite direction.

[0027] The second frame 2 is provided with a reinforcing rod 10, and an adjustment hole is provided at the other end of the reinforcing rod 10. The adjustment hole is connected to the movable support leg 302 by bolts.

[0028] like Figure 1 As shown, the reinforcing rod 10 serves to increase strength. During the process of adjusting the height of the conveyor belt, the angle between the reinforcing rod 10, the second frame 2, and the movable support leg 302 will change. The adjustment hole can prevent the reinforcing rod 10 from getting stuck.

[0029] Both the lower end of the first frame 1 and the lower end of the H-shaped support leg 9 are equipped with casters 11.

[0030] like Figure 1As shown, the caster wheel 11 has a locking structure, allowing it to move and stop at will.

[0031] A connecting ring 409 is fixed on the outer wall of the discharge pipe 402. Several balls 410 are rotatably installed on both the upper and lower ends of the connecting ring 409. A groove 411 is provided in the connecting seat 403, and the connecting ring 409 and the balls 410 are both set in the groove 411.

[0032] like Figure 5 As shown, under the action of the connecting ring 409 and the ball bearing 410, the connecting seat 403 is rotated and installed on the discharge pipe 402, thereby driving the guide pipe 404 and the telescopic pipe 405 to rotate, thereby changing the orientation of the discharge port, avoiding material accumulation and blockage, and improving conveying efficiency.

[0033] The feed tube 404 includes a straight tube and a bent tube. The straight tube is connected to the connecting seat 403 via a flange 412. A handle is fixed to the outer wall of the connecting seat 403. The handle can be held to drive the connecting seat 403 to rotate the feed tube 404. The rotation angle is no higher than 360° to avoid the electric push rod 407's wire from getting tangled. The telescopic tube 405 is fitted onto the bent tube.

[0034] like Figure 4 As shown, the feed pipe 404 and the connecting seat 403 are connected by a flange 412, which makes it easy to disassemble, transport and store when not in use.

[0035] Operating principle: When conveying grain into the truck bed, the conveyor belt must be installed before use. During installation, the first frame 1 and the second frame 2 are opened, and then the first frame 1 and the second frame 2 are fixed with bolts. Then, the H-shaped support legs are fitted onto the movable support legs 302. The discharge hopper 401 is then installed at the end of the second frame 2, and the telescopic tube 405 is installed on the connecting seat 403. The height of the conveyor belt is adjusted as needed by cranking the handle 309. After adjusting to the specified height, the handle 309 is locked by inserting the bolt 312 into the limiting hole 311. The motor is then started, and the motor drives the active conveyor belt. Roller 5 rotates, driving conveyor belt 7 to rotate. Material enters the hopper 401 along conveyor belt 7 and is discharged along guide pipe 404 and telescopic pipe 405. Before discharge, electric telescopic rod 407 is activated, and telescopic pipe 405 unfolds, so that the discharge port of telescopic pipe 405 reaches the designated material conveying position. During the material conveying process, the guide pipe 404 and telescopic pipe 405 are rotated by rotating connecting seat 403, changing the orientation of the discharge port of telescopic pipe 405. At the same time, the electric telescopic rod 407 can be controlled to slowly retract, changing the position of the discharge port, so that the material falls evenly into the hopper.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
