Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machine manufacturing, in particular to a shot sand lifting device of a hook-type shot blasting machine. Background Art

[0002] The elevator is an important component of the hook-type shot blasting machine. Its basic working process is as follows: the hopper fixed on the conveyor belt scrapes the shot material at the bottom of the elevator, and then, driven by the elevator motor, lifts the shot material to the top of the elevator. Finally, the shot material falls by centrifugal gravity and is input into the shot-sand separator.

[0003] Because the elevator relies on centrifugal gravity to drop materials, each time the materials are dropped, some materials in the upper part of the hopper will always be unable to fall into the shot sand separator and can only fall back into the elevator, increasing the ineffective lifting capacity, reducing work efficiency, and increasing production energy consumption. In addition, there may be large stones inside the shot sand, which may cause damage to the objects. Therefore, there is an urgent need for a shot sand lifting device for a hook-type shot blasting machine that has a high effective lifting capacity and can filter impurities. Utility Model Content

[0013] Compared with the prior art, the present invention provides a shot sand lifting device for a hook-type shot blasting machine, which has the following beneficial effects:

[0014] 1. The shot sand lifting device of the hook-type shot blasting machine starts the motor to drive the hopper to rotate along the conveyor belt. When it reaches the highest point, the hopper can be lifted, increasing the force of the hopper throwing downward, so that the shot sand inside the hopper can enter the transmission installation outlet more comprehensively to avoid the attachment of the shot sand.

[0028] Example 1:

[0029] See also Figure 1-7 The utility model provides a technical solution: a shot sand lifting device of a hook-type shot blasting cleaning machine, comprising a cover shell 1, a feed port 2 is fixedly installed on the left side of the cover shell 1, a discharge port 3 is fixedly installed on the right side of the cover shell 1, a lifting and filtering mechanism 4 is arranged inside the cover shell 1, a drying mechanism 5 is arranged on the back of the cover shell 1, and a sand storage tank 6 is opened inside the cover shell 1.

[0030] The lifting and filtering mechanism 4 includes a lifting component 41 and a screening component 42 . The lifting component 41 is arranged at the center of the housing 1 , and the screening component 42 is arranged inside the discharge port 3 .

A fixed ring 412 is fixedly installed on the top of the fixed plate 411. A motor 413 is fixedly installed on the outside of the fixed ring 412. The output end of the motor 413 extends to the inside of the cover shell 1 and is fixedly connected to a transmission shaft 415 at one end. The motor 413 is rotatably connected to the cover shell 1. A top roller 414 is fixedly installed on the outside of the transmission shaft 415. A lower roller 417 is rotatably connected to the inside of the cover shell 1. A conveyor belt 416 is rotatably connected between the lower roller 417 and the upper roller 414. A hopper 418 is slidably connected to the outside of the conveyor belt 416. A first spring 419 is fixedly installed on the outside of the hopper 418 to facilitate the height of the lifting hopper 418, so that the internal pellets are thrown out with greater force to avoid pellet adhesion.

[0032] Furthermore, the screening assembly 42 includes a rotating rod 427, which is rotatably connected to the back of the discharge port 3, and a second spring 428 is fixedly installed on the outside of the rotating rod 427. The rotating rod 427 extends to the inside of the discharge port 3 and is fixedly connected to one end of the screen 426, and a second extrusion rod 425 is fixedly installed on the side of the screen 426 away from the rotating rod 427. The outside of the second extrusion rod 425 is engaged with the first extrusion rod 424, and the outside of the first extrusion rod 424 is fixedly installed with a right-turning wheel 422, and the outside of the transmission shaft 415 is fixed with a left-turning wheel 421, and a belt 423 is rotatably connected between the left-turning wheel 421 and the right-turning wheel 422, so as to facilitate the screening of large stones inside the sand pellets and avoid damage to the objects.

[0033] Furthermore, the hoppers 418 are located at the center of the conveyor belt 416 , there are multiple groups of hoppers 418 , and the bottoms are semi-arc-shaped, so that the hoppers 418 fit better when passing through the upper roller 414 .

[0034] Furthermore, the second extrusion rod 425 is located at the center of one side of the screen 426, and the second extrusion rod 425 is slidably connected to the discharge port 3 to facilitate back and forth movement.

[0035] Embodiment 2:

[0036] See also Figure 8 , and combined with Example 1, it is further obtained that the drying mechanism 5 includes a heating tank 51, the heating tank 51 is fixedly mounted on the back of the cover 1, an air exchange port 52 is opened on the top of the heating tank 51, a resistance wire coil 53 is installed inside the heating tank 51, and the resistance wire coil 53 extends to the outside of the heating tank 51 and is fixedly mounted on one end thereof. An air inlet pipe 55 is fixedly mounted on the outside of the heating tank 51, a blower 56 is fixedly mounted on the end of the air inlet pipe 55 away from the heating tank 51, and an air supply pipe 57 is fixedly mounted on the side of the blower 56 away from the air inlet pipe 55, and the air supply pipe 57 is fixedly connected to the back of the cover 1, so that the shot sand can be dried.

[0037] Furthermore, the air supply pipe 57 is located at the center of the blower 56, and one end of the air supply pipe 57 away from the blower 56 extends to the inside of the sand storage tank 6, which facilitates drying, avoids the adhesion of the pellet sand, and reduces manual cleaning.

[0038] In actual operation, when this device is used, first connect the power supply head 54 to the power supply. When the power supply head 54 is energized, the resistance wire coil 53 inside the heating tank 51 is heated, so that the air entering from the air exchange port 52 is heated. Then, the blower 56 is turned on to rotate, so that the blower 56 sends the hot air to the air supply pipe 57 through the air inlet pipe 55. When the hot air in the air supply pipe 57 enters the interior of the sand storage tank 6, the pellets inside the sand storage tank 6 are dried to reduce the adhesion of the pellets. Then, the motor 413 is turned on to rotate, so that the transmission shaft 415 The upper roller 414 on the upper part rotates. When the upper roller 414 rotates, the conveying belt 416 on the upper roller 414 is driven to rotate, so that the lower roller 417 rotates together under the force. When the conveying belt 416 rotates, it drives the multiple groups of hoppers 418 on the conveying belt 416 to move. When the hopper 418 moves to the sand storage tank 6, the pellet sand inside the sand storage tank 6 is brought up by the rotation force. When the hopper 418 moves to the upper roller 414, the bottom of the hopper 418 will squeeze the upper roller 414, so that the hopper 418 moves along the conveying belt 41 6 slides, thereby making the head of the hopper 418 away from the conveyor belt 416. When the hopper 418 rotates to the highest point, the rotational force causes the pellets inside the hopper 418 to be thrown onto the screen 426. Because the height of the hopper 418 is raised, the pellets are thrown with greater force and are not easy to adhere to the inside of the hopper 418, thereby improving the utilization rate of the pellets. When the hopper 418 is away from the upper roller 414, it is reset by the rebound of the first spring 419. When the motor 413 is turned on, the left-hand wheel 421 outside the transmission shaft 415 is driven to rotate, driving the belt 423 on the left. The right-turning wheel 422 rotates. When the right-turning wheel 422 rotates, it will squeeze the second squeezing rod 425 engaged with it. When the second squeezing rod 425 is squeezed, it drives the rear screen 426 to move backward, driving the rotating rod 427 to move backward at the back of the discharge port 3. When the first squeezing rod 424 does not squeeze the second squeezing rod 425, the screen 426 no longer pushes the rotating rod 427 to move backward. At this time, the second spring 428 resets the rotating rod 427 through the pulling force, thereby realizing the back and forth movement of the screen 426, and realizing the screening and filtering of debris.
