[0040] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Reference Figure 1-Figure 4A waste sand lifting and transportation device for coated sand regeneration comprises: a lifting box 1, the lifting box 1 comprises: a feed port 101, which is opened at the bottom of one side of the lifting box 1; a discharge port 102, which is opened at the top of the other side of the lifting box 1; through the setting of the feed port 101 and the discharge port 102, the continuous input and output of waste sand is realized, and the efficiency of waste sand treatment is improved. Two transmission wheels 2 are installed in the lifting box 1; a traction member 3 is connected to the two transmission wheels 2; the coordinated use of the transmission wheel 2 and the traction member 3 enables the hopper 5 to move stably in the lifting box 1, ensuring the smooth transportation of the waste sand, multiple control parts 4, which are installed on the traction member 3; multiple hoppers 5, are respectively installed on multiple control parts 4, and are set to move back and forth on one side of the control part 4; the control part 4 includes a moving seat 402 and a cam 404, a moving groove 401 is opened on one side of the control part 4, the moving seat 402 is installed in the moving groove 401, the cam 404 is installed on the side wall of the moving groove 401 and contacts with one side of the moving seat 402, the moving seat 402 is connected to the hopper 5, and the traction member 3 drives the control part 4 to move together. After the control part 4 drives the hopper 5 to move to the top area of ​​the lifting box 1, the hopper 5 can be controlled to shake back and forth, and the waste sand particles with high humidity can be discharged into the discharge port 102 to avoid the waste sand from accumulating and sticking in the hopper 5.

[0042] Reference Figure 2 and Figure 4 The control unit 4 also includes: a first bevel gear 405, coaxially mounted on one side of the cam 404; a rotating shaft 407, mounted in the movable groove 401, one end of the rotating shaft 407 passes through the movable groove 401 and extends to the outside of the control unit 4, and is connected to a driving wheel 408; a second bevel gear 406, mounted on the other end of the rotating shaft 407, the side wall of the lifting box 1 is connected to a rack 103, the driving wheel 408 is connected to the rack 103, and the rack 103 is arc-shaped.

[0043] The driving wheel 408 moves along with the control part 4 on the traction member 3. When the control part 4 moves to the top area of ​​the lifting box 1, since the rack 103 is fixed, the linear motion of the driving wheel 408 along the direction of the rack 103 is converted into rotational motion during the process of meshing with the rack 103. Due to the meshing action of the rack 103 and the driving wheel 408, the driving wheel 408 can roll on the rack 103, thereby driving the rotating shaft 407 to rotate, and the rotating shaft 407 drives the second bevel gear 406 to rotate, and the second bevel gear 406 drives the first bevel gear 405 to rotate, and the first bevel gear 405 drives the cam 404 to rotate. The cam 404 repeatedly squeezes the moving seat 402 during rotation, and the moving seat 402 moves in the moving groove 401 and squeezes the first elastic member 403, so that the moving seat 402 drives the hopper 5 to shake on the control part 4.

[0044] Reference Figure 4A first elastic member 403 is connected to one side of the movable seat 402 , and one end of the first elastic member 403 is connected to the side wall of the movable groove 401 .

[0045] The first elastic member 403 is made of a stainless steel spring, and may also be made of an alloy spring. The first elastic member 403 may provide an initial restoring force for the movable seat 402 .

[0046] Reference Figure 3 and Figure 4 The hopper 5 includes: two push plates 501, which are symmetrically installed in the hopper 5; two transmission rods 502, one end of which is installed on the push plates 501, and the other end passes through the hopper 5 and is connected to an anti-slip sheet; a second elastic member 503 is connected to the transmission rod 502, one end of the second elastic member 503 is in contact with the anti-slip sheet, and the other end is in contact with one side of the hopper 5.

[0047] When the hopper 5 shakes, it will drive the transmission rods 502 on both sides to approach the two sides of the control part 4. At the same time, the transmission rods 502 are squeezed by the control part 4 to drive the push plate 501 to move. During the movement, the anti-slip sheet will squeeze the second elastic member 503. The second elastic member 503 can provide an initial restoring force for the anti-slip sheet and the push plate 501, so that the push plate 501 can move when the hopper 5 shakes, and push the waste sand accumulated in the hopper 5 to be quickly discharged. The second elastic member 503 is made of a stainless steel spring.

[0048] During use, waste sand is continuously input into the lifting box 1 through the feed port 101 at the bottom of one side of the device. At the same time, the two driving wheels 2 run stably in the lifting box 1, and the traction member 3 connected therebetween forms a closed circulation path. Multiple control parts 4 are evenly installed on the traction member 3, and each control part 4 is equipped with a hopper 5 for carrying waste sand. As the driving wheel 2 rotates, the traction member 3 drives the control part 4 and the hopper 5 to move upward along the inside of the lifting box 1. In this process, the waste sand is gradually filled into the hopper 5. When the control unit 4 and the hopper 5 move to the top area of ​​the lifting box 1 with the traction member 3, the driving wheel 408 begins to mesh with the rack 103 on the side wall of the lifting box 1. Since the rack 103 is fixed, the linear motion of the driving wheel 408 along the direction of the rack 103 is converted into rotational motion during the meshing process of the rack 103. The driving wheel 408 drives the rotating shaft 407 to rotate, the rotating shaft 407 drives the second bevel gear 406 to rotate, the second bevel gear 406 drives the first bevel gear 405 to rotate, and the first bevel gear 405 drives the cam 404. The cam 404 repeatedly squeezes the movable seat 402 during the rotation, and the movable seat 402 moves in the movable groove 401 and squeezes the first elastic member 403, so that the movable seat 402 drives the hopper 5 to shake on the control unit 4. The rotation of the cam 404 causes it to repeatedly squeeze the movable seat 402, and the movable seat 402 moves in the movable groove 401 and squeezes the first elastic member 403. This squeezing provides an initial restoring force for the movable seat 402, so that the movable seat 402 can drive the hopper 5 to shake on the control unit 4. The hopper 5 is During the process, the two push plates 501 inside it are moved by the driving rod 502. The movement of the push plates 501 pushes the waste sand accumulated in the hopper 5, so that it is quickly discharged through the discharge port 102. The second elastic member 503 on the driving rod 502 provides an initial restoring force for the anti-slip sheet and the push plate 501, ensuring that the push plate 501 can return to its initial position after shaking. After the waste sand is discharged, the control unit 4 and the hopper 5 continue to move downward with the traction member 3 and return to the bottom area of ​​the lifting box 1, preparing for the next round of waste sand lifting and transportation.

[0049] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0050] By controlling the hopper 5 to shake when passing through the discharge port 102, it is avoided that waste sand accumulates and gets clogged in the hopper 5 during discharge, thereby improving the fluidity and stability of the production line.

[0051] Through the shaking of the control unit 4 and the movement of the push plate 501 in the hopper 5, the device can effectively discharge the waste sand from the hopper 5, avoiding the residue and accumulation of waste sand in the hopper 5, reducing the loss and waste of waste sand, and improving the recovery rate of waste sand.
