Description

Technical Field

[0001] This utility model relates to the field of resin sand production technology, and in particular to a belt conveyor for resin sand regeneration. Background Technology

[0002] In the process of resin sand production, it is often necessary to transport resin sand from a low place to a high place. Belt elevators are often used for this purpose. They have advantages such as simple structure, low maintenance cost, high conveying efficiency, high lifting height, stable operation, and wide application range.

[0003] Patent CN221955127U discloses a bucket elevator for grain conveying, including a base plate, a lifting mechanism, and a height adjustment mechanism. The base plate has a mounting base fixedly connected to its upper left side. The lifting mechanism includes a shell, rotating rollers, a transmission belt, and bucket troughs. The bottom end of the shell is rotatably connected to the upper end of the mounting base. The rotating rollers are rotatably connected between the front and rear inner walls of the upper and lower ends of the shell, respectively. The two rotating rollers are connected by transmission belt. The bucket troughs are evenly arranged on the outer surface of the transmission belt and are slidably connected to the inside of the shell. The height adjustment mechanism is located at the upper end of the base plate and is rotatably connected to the right side of the shell.

[0004] In the above case, the screw rotates to move the connecting block, which in turn drives the connecting rod to rotate the lifting mechanism to adjust the position of the discharge pipe. However, when the material enters the discharge pipe at the top, due to gravity, not all of the material will enter the discharge pipe; some will fall back into the lifting mechanism, resulting in low discharge efficiency. Furthermore, when the lifting mechanism is feeding material, the weight of the material plus its own weight will compress the connecting rod and put significant pressure on the threaded connection between the screw and the connecting block, which can easily cause the connecting block to dislodge, making the lifting mechanism unstable.

[0005] Therefore, this utility model provides a belt conveyor for conveying resin sand regeneration to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide a belt conveyor for resin sand regeneration, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor for resin sand regeneration, comprising a main body for transporting resin sand, a lifting box fixedly connected to the top of the main body, a discharge pipe fixedly connected to one side of the top of the lifting box, an extension pipe slidably connected to the outer side of the discharge pipe away from the lifting box, a rotating shaft rotatably connected to the inner side of the discharge pipe, a baffle plate fixedly connected to the side of the rotating shaft near the lifting box, the end of the baffle plate extending into the interior of the lifting box, mounting boxes fixedly connected to both sides of the discharge pipe, the two ends of the rotating shaft respectively penetrating the discharge pipe and extending into the inner sides of the two mounting boxes, and a rotating block fixedly connected thereto, located on the side of the rotating shaft away from the baffle plate, a fixed seat fixedly connected to the top of the discharge pipe; and a spring-loaded assembly for springing the rotating shaft, the spring-loaded assembly being connected to the rotating block, the spring-loaded assembly including a right-angled spring fixedly connected to the rotating block, an inner support spring and an outer support spring sequentially fixedly connected to one side of the right-angled spring.

[0008] In a preferred embodiment, the bottom end of the lifting box away from the discharge pipe is fixedly connected to the feed pipe, and the top and bottom ends of the inner side of the lifting box are rotatably connected to drive shafts, and the outer sides of the two drive shafts are rotatably connected to the same transmission belt.

[0009] In a preferred embodiment, a plurality of feeding hoppers are fixedly connected to the outer side of the transmission belt, and the side of the feeding hopper away from the transmission belt is in close contact with the inner wall of the lifting box.

[0010] In a preferred embodiment, a second motor is fixedly connected to the top of the outer side of the lifting box, and the output end of the second motor is fixedly connected to the drive shaft at the top.

[0011] In a preferred embodiment, the right-angle spring is L-shaped, with its bottom fixedly connected to the top of the rotating block and its vertical part fixedly connected to the top of the inner side of the mounting box. The two ends of the inner support spring and the outer support spring are respectively fixedly connected to the bottom and vertical part of the right-angle spring.

[0012] In a preferred embodiment, a lead screw is rotatably connected to the inner side of the fixed base, and a No. 1 motor is fixedly connected to the side of the fixed base away from the extension tube, with its output end fixedly connected to the lead screw.

[0013] In a preferred embodiment, a sliding block is threadedly connected to the outer side of the lead screw, and the bottom of the sliding block is fixedly connected to the extension tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting up a spring-loaded component, a rotating shaft, a rotating block, and a baffle plate, allows the baffle plate to block and guide the material inside the lifting box, causing it to slide down to the discharge pipe, thus preventing some material from falling directly and failing to enter the discharge pipe. The spring-loaded component also ensures that when the baffle plate is squeezed and rotated back by the feeding hopper, the right-angled spring will deform and store the rebound force, which can push the baffle plate back to its original position when it is no longer squeezed, thus ensuring the normal operation of the baffle plate.

[0016] This utility model, by setting a fixed seat, a lead screw, a sliding block, and an extension tube, allows the lead screw and the sliding block to cooperate, driving the extension tube to slide outside the discharge tube, thereby adjusting the discharge position without moving the lifting box to achieve the purpose, thus ensuring the stability of the lifting box.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4This utility model provides a belt conveyor for resin sand regeneration, including a main body 1 for transporting resin sand. A lifting box 2 is fixedly connected to the top of the main body 1. A discharge pipe 3 is fixedly connected to one side of the top of the lifting box 2. An extension pipe 4 is slidably connected to the outer side of the end of the discharge pipe 3 away from the lifting box 2. A fixed seat 10 is fixedly connected to the top of the discharge pipe 3. A feed pipe 18 is fixedly connected to the bottom end of the lifting box 2 away from the discharge pipe 3. A drive shaft 14 is rotatably connected to both the top and bottom ends of the inner side of the lifting box 2. The same transmission belt is rotatably connected to the outer side of the two drive shafts 14. 15. Several feeding hoppers 16 are fixedly connected to the outer side of the transmission belt 15. The side of the feeding hopper 16 away from the transmission belt 15 is in close contact with the inner wall of the lifting box 2. A second motor 17 is fixedly connected to the top of the outer side of the lifting box 2. The output end of the second motor 17 is fixedly connected to the drive shaft 14 at the top. A lead screw 11 is rotatably connected to the inner side of the fixed seat 10. A first motor 13 is fixedly connected to the side of the fixed seat 10 away from the extension tube 4. Its output end is fixedly connected to the lead screw 11. A moving block 12 is threadedly connected to the outer side of the lead screw 11. The bottom of the moving block 12 is fixedly connected to the extension tube 4.

[0025] Start motor 13 to drive screw 11 to rotate. The moving block 12 on screw 11 moves, which in turn moves extension tube 4 to the appropriate discharge position. Resin sand is added through feed pipe 18. Start motor 17 to drive drive shaft 14 at the top to rotate. The two drive shafts 14 are connected by transmission belt 15, so transmission belt 15 starts to run. The hopper 16 moves with transmission belt 15 and begins to scoop resin sand from feed pipe 18 and transport it to a higher position.

[0026] The lead screw 11, through its helical structure design, achieves a close fit with the shift block 12. Driven by the shift block 12, the extension tube 4 can slide on the outside of the discharge tube 3, thereby achieving precise adjustment of the discharge position. This adjustment method is not only flexible and versatile, but also meets the needs of different working environments and material conveying, greatly improving the adaptability and practicality of the equipment. It avoids the cumbersome steps of moving the entire lifting box 2 to complete the discharge position adjustment in the traditional method, thus ensuring the stability and reliability of the lifting box 2 during the conveying process.

[0027] Please see Figures 1-4A rotating shaft 5 is rotatably connected to the inner side of the discharge pipe 3. A baffle plate 6 is fixedly connected to the side of the rotating shaft 5 near the lifting box 2, and the end of the baffle plate 6 away from the rotating shaft 5 extends into the interior of the lifting box 2. Mounting boxes 8 are fixedly connected to both sides of the discharge pipe 3. The two ends of the rotating shaft 5 pass through the discharge pipe 3 and extend into the inner sides of the two mounting boxes 8, and are fixedly connected to a rotating block 7 located on the side of the rotating shaft 5 away from the baffle plate 6. A spring-loaded assembly 9 is used to spring back the rotating shaft 5. The component 9 is connected to the rotating block 7. The spring-loaded assembly 9 includes a right-angled spring 901 fixedly connected to the rotating block 7. An inner support spring 902 and an outer support spring 903 are fixedly connected to one side of the right-angled spring 901 in sequence. The right-angled spring 901 is L-shaped. Its bottom is fixedly connected to the top of the rotating block 7, and its vertical part is fixedly connected to the top of the inner side of the mounting box 8. The two ends of the inner support spring 902 and the outer support spring 903 are fixedly connected to the bottom and vertical part of the right-angled spring 901, respectively.

[0028] When the feeding hopper 16 reaches the vicinity of the discharge pipe 3, the material will fall down and slide into the discharge pipe 3 through the obstruction and guidance of the baffle plate 6. When the feeding hopper 16 touches the baffle plate 6, it will squeeze the baffle plate 6 to rotate downward into the discharge pipe 3. At the same time, the rotating block 7 squeezes the right-angle spring 901 to deform it. After the feeding hopper 16 moves past, the right-angle spring 901 returns to its original shape, pushing the baffle plate 6 back to its original position. The material slides out along the discharge pipe 3 and the extension pipe 4 and falls into the predetermined position.

[0029] Precise control of the position and angle of the baffle plate 6 is crucial for blocking and guiding the material. During the lifting process, the baffle plate 6 will fit tightly inside the lifting box 2, forming an effective barrier to prevent the material from falling directly before reaching the discharge pipe 3. This ensures that the material can slide smoothly into the discharge pipe 3 and be conveyed out along the predetermined path. When the feeding hopper 16 contacts the baffle plate 6, the baffle plate 6 will be squeezed and rotate around the rotating shaft 5, thereby retracting some space to allow the feeding hopper 16 to pass. Once the feeding hopper 16 passes, the baffle plate 6 will no longer be squeezed, and the right-angle spring 901 will quickly release the stored rebound force, pushing the baffle plate 6 back to its original position to continue to play its role in blocking and guiding the material.

[0030] The working principle and usage process of this utility model are as follows: Starting motor 13 drives the lead screw 11 to rotate, causing the moving block 12 on the lead screw 11 to move, thereby moving the extension tube 4 to the appropriate discharge position. Resin sand is added through the feed pipe 18. Then, starting motor 17 drives the top drive shaft 14 to rotate. The two drive shafts 14 are connected by a transmission belt 15, causing the transmission belt 15 to start operating. The feeding hopper 16 moves along with the transmission belt 15, beginning to scoop resin sand from the feed pipe 18. The grease is transported to a high place. When the feeding hopper 16 reaches the vicinity of the discharge pipe 3, the material will fall down and slide into the discharge pipe 3 through the obstruction and guidance of the baffle plate 6. When the feeding hopper 16 touches the baffle plate 6, it will squeeze the baffle plate 6 to rotate downward into the discharge pipe 3. At the same time, the rotating block 7 squeezes the right-angle spring 901 to deform it. After the feeding hopper 16 moves past, the right-angle spring 901 returns to its original shape, pushing the baffle plate 6 back to its original position. The material slides out along the discharge pipe 3 and the extension pipe 4 and falls into the predetermined position.
