Description

Technical Field

[0001] This utility model relates to the field of coated sand technology, specifically to a waste sand lifting and transportation device for coated sand recycling. Background Technology

[0002] Coated sand was invented by Dr. Kronen of Germany during World War II. The process involves mechanically mixing powdered thermosetting phenolic resin with raw sand and curing it upon heating. Later, it was developed into a process using thermoplastic phenolic resin, a latent curing agent (hexamethylenetetramine), and a lubricant, formulated through a specific coating process. When the coated sand is heated, the resin coating the surface of the sand grains melts. Under the action of the methylene groups released from the decomposition of hexamethylenetetramine, the molten resin rapidly transforms from a linear structure to a non-molten three-dimensional structure, thus solidifying the coated sand. Waste sand generated during the production of coated sand is usually transferred using a lifting and conveying device to avoid resource waste.

[0003] In the existing technology of waste sand lifting and transportation equipment, some waste sand is usually spilled on the ground during discharge. The waste sand piled on the ground increases the difficulty of subsequent cleaning. Therefore, there is a need for a waste sand lifting and transportation device for coated sand recycling. Utility Model Content

[0004] The purpose of this invention is to provide a waste sand lifting and transportation device for coated sand recycling, which solves the problems mentioned in the background art.

[0005] This application provides a waste sand lifting and transport device for coated sand recycling, including a plate and a rotating shaft. A protective box is fixedly connected to one outer wall of the plate. A hydraulic rod is fixedly connected inside the protective box. The piston rod of the hydraulic rod passes through the outside of the protective box and is fixedly connected to a connecting block. A fixing frame is fixedly connected to the outer wall of the connecting block away from the plate. A guide plate is rotatably connected inside the fixing frame via a rotating shaft. A connecting frame is fixedly connected to the bottom of the end of the guide plate away from the fixing frame. A telescopic adjustment rod is rotatably connected inside the connecting frame. The end of the telescopic adjustment rod away from the connecting frame abuts against the ground. A transfer trolley is provided below the end of the telescopic adjustment rod on the guide plate.

[0006] In operation, waste sand enters the conveying cylinder through the feed pipe. The motor's output shaft drives the conveying screw to rotate, lifting and transporting the waste sand from low to high. The waste sand is then discharged into a storage device through the discharge pipe for later processing. Additionally, the piston rod of the hydraulic rod pushes the connecting block and the fixing frame to rise and fall, causing the guide plate at one end of the discharge pipe to lift. Since the fixing frame and the guide plate are connected by a rotating shaft, the other end of the guide plate tilts downwards. Once the guide plate reaches the appropriate height, the length of the telescopic adjustment rod is extended, allowing the end of the telescopic adjustment rod away from the guide plate to rest on the ground. This allows for flexible adjustment of the guide plate's height and tilt angle. The guide plate prevents spilled waste sand from falling and accumulating on the ground during discharge. Spilled waste sand can slide into a transfer trolley via the guide plate, which then transfers it back to the feed pipe of the conveying cylinder for transport, preventing resource waste and reducing the difficulty of subsequent ground cleanup.

[0007] Optionally, a reinforcing plate and a fixing plate are symmetrically fixedly connected to the top of the plate. A conveying cylinder is inclinedly arranged at the top of the reinforcing plate and the fixing plate. A motor is fixedly connected to one end of the conveying cylinder. The output shaft of the motor passes through the interior of the conveying cylinder and is fixedly connected to a conveying screw. A discharge pipe is fixedly connected to the conveying cylinder below the motor. The discharge pipe is located above the guide plate. A feed pipe is fixedly connected to the top of the end of the conveying cylinder away from the motor.

[0008] By adopting the above technical solution, waste sand can be transported to the inside of the conveying cylinder through the feed pipe. The output shaft of the motor can drive the conveying screw to rotate, and the waste sand is lifted and transported from low to high through the conveying screw, and then discharged through the discharge pipe.

[0009] Optionally, a hopper is fixedly connected to the top end of the feed pipe.

[0010] By adopting the above technical solution, leakage can be avoided when waste sand is transported into the conveyor cylinder.

[0011] Optionally, reinforcing blocks are fixedly connected to both outer walls of the conveying cylinder, and bolts are threaded through the reinforcing blocks and connected to the fixing plate.

[0012] By adopting the above technical solution, the stability of the conveyor cylinder installation has been further improved.

[0013] Optionally, the cross-section of the fixing frame is U-shaped.

[0014] By adopting the above technical solution, it is beneficial to adjust the rotation of the guide plate.

[0015] Optionally, two telescopic adjustment rods are provided, and the two telescopic adjustment rods are arranged symmetrically on the left and right.

[0016] By adopting the above technical solution, the stability of the guide plate has been further improved.

[0017] Optionally, the outer wall of the protective box is provided with a heat dissipation opening.

[0018] By adopting the above technical solution, heat dissipation of the hydraulic rod is facilitated.

[0019] Optionally, a guide groove is provided at the top of the guide plate along its length.

[0020] By adopting the above technical solution, it is possible to prevent waste sand from sliding off both sides of the guide plate.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application, through the cooperation of a fixed frame, hydraulic rod, telescopic adjustment rod and rotating shaft, can flexibly adjust the height and tilt angle of the guide plate. The guide plate can prevent the spilled waste sand from falling and accumulating on the ground when discharging from the discharge pipe. The spilled waste sand can slide into the transfer trolley through the guide plate, and the transfer trolley can transfer the waste sand back to the feed pipe of the conveyor cylinder for transportation, avoiding waste of resources and reducing the difficulty of subsequent ground cleaning.

The piston rod of the hydraulic rod 12 passes through the outside of the protective box 11 and is fixedly connected to a connecting block 2. A fixing frame 1 is fixedly connected to the outer wall of the connecting block 2 away from the plate body 9. A guide plate 13 is rotatably connected inside the fixing frame 1 via the rotating shaft 20. A connecting frame 18 is fixedly connected to the bottom of the end of the guide plate 13 away from the fixing frame 1. A telescopic adjustment rod 14 is rotatably connected inside the connecting frame 18. The end of the telescopic adjustment rod 14 away from the connecting frame 18 abuts against the ground. A transfer trolley 15 is provided below the end of the telescopic adjustment rod 14 of the guide plate 13.

[0030] In the technical solution of this utility model, such as Figure 1 and Figure 3 As shown, a reinforcing plate 8 and a fixing plate 10 are symmetrically fixedly connected to the top of the plate 9. A conveying cylinder 16 is inclinedly arranged at the top of the reinforcing plate 8 and the fixing plate 10. A motor 3 is fixedly connected to one end of the conveying cylinder 16. The output shaft of the motor 3 passes through the interior of the conveying cylinder 16 and is fixedly connected to a conveying screw 19. A discharge pipe 17 is fixedly connected to the bottom of the conveying cylinder 16 below the motor 3. The discharge pipe 17 is located above the guide plate 13. A feed pipe 7 is fixedly connected to the top of the end of the conveying cylinder 16 away from the motor 3. Waste sand can be conveyed into the interior of the conveying cylinder 16 through the feed pipe 7. The output shaft of the motor 3 can drive the conveying screw 19 to rotate. The conveying screw 19 completes the lifting and transportation of waste sand from low to high, and then discharges it through the discharge pipe 17.

[0031] In the technical solution of this utility model, such as Figure 1 As shown, a hopper 6 is fixedly connected to the top of the feed pipe 7; this can prevent the waste sand from spilling when it is transported into the conveying cylinder 16.

[0032] In the technical solution of this utility model, such as Figure 1 As shown, reinforcing blocks 5 are fixedly connected to both outer walls of the conveying cylinder 16, and bolts 4 are threaded through the reinforcing blocks 5. The bolts 4 are threadedly connected to the fixing plate 10, which further improves the stability of the conveying cylinder 16 installation.

[0033] In the technical solution of this utility model, such as Figure 1 As shown, the cross-section of the fixing frame 1 is U-shaped, which facilitates the rotation and adjustment of the guide plate 13.

[0034] In the technical solution of this utility model, such as Figure 2 As shown, there are two telescopic adjustment rods 14, which are symmetrically arranged on the left and right sides; this further improves the stability of the guide plate 13.

[0035] In the technical solution of this utility model, such as Figure 1 As shown, the outer wall of the protective box 11 has a heat dissipation opening, which is beneficial for the heat dissipation of the hydraulic rod 12.

[0036] In the technical solution of this utility model, such as Figure 1 As shown, a guide groove 21 is provided at the top of the guide plate 13 along the length direction; this can prevent waste sand from sliding off from both sides of the guide plate 13.

[0037] In use, waste sand enters the conveying cylinder 16 through the feed pipe 7. The output shaft of the motor 3 drives the conveying screw 19 to rotate, lifting and transporting the waste sand from low to high. Then, the waste sand is discharged into the storage equipment through the discharge pipe 17 for storage, facilitating subsequent processing. In addition, the piston rod of the hydraulic rod 12 can push the connecting block 2 and the fixing frame 1 to rise and fall, thereby causing the guide plate 13 located at one end of the discharge pipe 17 to rise. Since the fixing frame 1 and the guide plate 13 are rotatably connected by the rotating shaft 20, the other end of the guide plate 13 will tilt downward. After the guide plate 13 reaches the appropriate height, the length of the telescopic adjustment rod 14 is extended so that the end of the telescopic adjustment rod 14 away from the guide plate 13 is supported on the ground. This allows for flexible adjustment of the height and tilt angle of the guide plate 13. The guide plate 13 prevents spilled waste sand from falling and accumulating on the ground when the discharge pipe 17 discharges material. The spilled waste sand can slide into the transfer cart 15 through the guide plate 13, and then be transferred back to the feed pipe 7 of the conveying cylinder 16 for transportation, thus avoiding waste of resources and reducing the difficulty of subsequent ground cleaning.
