Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting machines and relates to an automatic lifting mechanism for a shot blasting machine. Background Art

[0002] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of the casting. The shot blasting machine can simultaneously remove sand, core and clean the casting. In some areas, it is also verbally called a sandblasting machine or a sandblasting machine. It is a processing technology that uses a shot blaster to throw steel sand and steel shots at high speed and impact on the surface of the material object. Compared with other surface treatment technologies, it is faster and more effective, and can be used for the casting process after partial retention or stamping. The lifting mechanism pulls the chain upward through the motor to lift the hopper, so that the hopper is turned up so that its discharge port can be aligned with the feed port of the shot blasting machine. At the same time, the special design of the hopper also facilitates workers to load materials.

[0003] When the existing shot blasting machine is loaded, the motor drives the hopper to flip upward through the chain. Since the existing hopper mouth does not have a corresponding blocking structure, when the hopper is flipped from vertical to horizontal and then to an oblique state, part of the internal raw materials have leaked along the bucket slope and have not entered the shot blasting machine. At the same time, at this time, the raw materials at the bottom of the bucket move with the hopper, and the raw materials on the top layer do not move along the bucket slope, but will tend to overturn, so that the raw materials here cannot smoothly enter the shot blasting machine.

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-5As shown, an automatic lifting mechanism for a shot blasting machine includes a shot blasting machine 1 and a lifting device 2, wherein a bracket 21 is installed in the lifting device 2, a motor 22 is installed above the bracket 21, a support plate 23 is installed at the rear side of the bracket 21, a hopper 3 is provided below the bracket 21, the hopper 3 is divided into a hopper slope 31 and a hopper bottom 32, a movable frame 33 is installed outside the hopper bottom 32, side plates 4 are symmetrically installed at the rear side of the hopper 3, support rods 41 are installed through the side plates 4, and electric telescopic Rod 5, a push rod 51 is installed at one end of the electric telescopic rod 5, a connecting rod 52 is installed at one end of the push rod 51, and a sliding rod 53 is installed at one end of the connecting rod 52. A paddle plate 54 is installed on the sliding rod 53, a fixed block 6 is installed on one side of the movable frame 33, a screw rod 61 is installed through the fixed block 6, a connecting frame 62 is installed on the top of the screw rod 61, and a material blocking plate 63 is installed on one side of the connecting frame 62, a wedge block 7 is installed on the inner wall of the bucket slope 31, and a long plate 71 is installed at the edge of the discharge port of the bucket slope 31.

[0027] In this embodiment, when the original hopper 3 is flipped from a vertical state to a horizontal state and then to an inclined state, part of the raw materials will roll down along the hopper slope 31. When there is too much raw material in the hopper bottom 32, the raw materials on the top layer will tend to tip over due to inertia when the hopper 3 moves, and spillage may occur. Therefore, this problem is solved in this case by installing a paddle plate 54 and a material baffle plate 63.

[0028] Combination Figure 1 , Figure 2 As shown, the motor 22 is electrically connected to an external power source, the support plate 23 is symmetrically arranged, and the support plate 23 and the bracket 21 are staggered and facing the shot blasting machine 1. A hook is installed on the movable frame 33, and a chain is installed at the hook. The motor 22 and the movable frame 33 are connected by a chain, and the bucket slope 31 and the bucket bottom 32 are installed obliquely.

[0029] Furthermore, the shot blasting machine 1 belongs to the prior art, which drives the hopper 3 through the motor 22 to pull the chain, so that the hopper 3 rotates clockwise on the support plate 23 through the rear support rod 41, and at the same time, the movable frame 33 and the hopper 3 are rotationally connected, so the movable frame 33 will not hinder the rotation movement of the hopper 3.

[0030] Combination Figure 1 , Figure 2 As shown, the movable frame 33 is U-shaped, and the two ends of the movable frame 33 are rotatably connected to the hopper 3 through a pin. The side plate 4 and the support plate 23 are located on the same side, the side plate 4 is fixedly connected to the support rod 41, and the two ends of the support rod 41 are rotatably connected to the support plate 23.

[0031] Furthermore, the hopper 3 is rotatably connected to the support plate 23 through the support rod 41 on the rear side, and the support rod 41 and the side plate 4 are fixedly connected. When the motor 22 lifts the hopper 3 upward, one end of the hopper 3 rotates based on the support rod 41. At the same time, as the hopper 3 flips, the movable frame 33 also rotates in the opposite direction outside the hopper 3. Finally, one end of the hopper 3 enters the feed port of the shot blasting machine 1.

[0032] Combination Figure 2 , Figure 3 As shown, the bottom of the electric telescopic rod 5 is rotatably connected to the hopper 3, one end of the push rod 51 is provided with a U-shaped opening, and the connecting rod 52 is inserted into the U-shaped opening, and the connecting rod 52 and the push rod 51 are rotatably connected. The connecting rod 52 is fixedly connected to the sliding rod 53, and the sliding rod 53 passes through the hopper 3 horizontally, and the sliding rod 53 and the hopper 3 are rotatably connected.

[0033] Furthermore, the connecting rod 52 is inserted into the U-shaped opening and is rotatably connected thereto. When the electric telescopic rod 5 is shortened forward or backward, the connecting rod 52 is pulled forward or backward through the push rod 51, so that the connecting rod 52 drives the sliding rod 53 to rotate clockwise or counterclockwise, and then the internal paddle 54 appears in an open or closed state. When the hopper 3 is extended into the feed inlet of the shot blasting machine 1, the paddle 54 is open, and when the hopper 3 is not extended into the feed inlet of the shot blasting machine 1, the paddle 54 is closed.

[0034] Combination Figure 2 , Figure 3 As shown, the fixing block 6 has a thread meshing with the screw rod 61 on the inner wall where the screw rod 61 passes through, and the top of the screw rod 61 is rotatably connected to the connecting frame 62, and the connecting frame 62 is U-shaped. The connecting frame 62 stands outside the hopper 3, and the baffle plate 63 is inserted in the hopper 3, and the side profile of the baffle plate 63 is triangular.

[0035] Furthermore, the height of the connecting frame 62 is adjusted by rotating the screw rod 61, thereby changing the height of the internal baffle plate 63, and at the same time, the bevel of the baffle plate 63 faces inward, so that the poured raw materials can move along the baffle plate 63 into the hopper 3.

[0036] Combination Figure 4 , Figure 5 As shown, the outer contour of the wedge block 7 is a trapezoid, and the oblique side of the wedge block 7 faces the inner side of the bucket slope 31, and the long plate 71 is installed obliquely.

[0037] Furthermore, the long plate 71 is installed obliquely without hindering the discharge of materials. At the same time, the wedge blocks 7 installed on both sides appropriately reduce the size of the discharge port without hindering the discharge of materials, thereby preventing the raw materials from splashing during unloading due to the discharge port being too large.

[0038] The working principle of the utility model is:

[0039] The motor 22 pulls the chain to drive the hopper 3, and at the same time, the movable frame 33 and the hopper 3 are rotatably connected, so that the hopper 3 rotates clockwise on the support plate 23 through the rear support rod 41. The hopper 3 is rotatably connected to the support plate 23 through the rear support rod 41, and the support rod 41 and the side plate 4 are fixedly connected. When the motor 22 pulls up the hopper 3, one end of the hopper 3 rotates clockwise based on the support rod 41. As the hopper 3 flips, the movable frame 33 rotates counterclockwise, and finally one end of the bucket slope 31 enters the feed port of the shot blasting machine 1.

[0040] During the movement of the hopper 3 from a vertical state to a horizontal state and then to an inclined state toward the shot blasting machine 1, the internal paddle 54 is always in a closed state, and the inner wall of the paddle 54 abuts against the long plate 71 to form a closed state, preventing part of the raw materials from leaking out along the bucket slope 31. When the bucket slope 31 enters the feed port of the shot blasting machine 1, the electric telescopic rod 5 extends forward and pulls the connecting rod 52 forward through the push rod 51, so that the connecting rod 52 drives the sliding rod 53 to rotate clockwise, and at this time the electric telescopic rod 5 itself will also rotate to a certain extent, and then the internal paddle 54 is in an open state, and the material can be discharged normally.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
