Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting machines, in particular to a high-efficiency shot blasting machine. Background Art

[0002] The shot blaster uses a high-speed rotating impeller to throw small steel or iron shots to hit the surface of the parts at high speed, so the oxide layer on the surface of the parts can be removed. At the same time, the steel or iron shots hit the surface of the parts at high speed, causing the lattice on the surface of the parts to be distorted and deformed, increasing the surface hardness. This is a method of cleaning the surface of the parts, so the shot blaster is the ultimate embodiment of the production efficiency of the entire set of equipment.

[0003] There are many types of shot blasters. For example, the prior art patent CN210232704U discloses a high-efficiency shot blaster: it includes an impeller front baffle, an impeller rear baffle and blades, and a plurality of the blades are arranged circumferentially between the impeller front baffle and the impeller rear baffle; the blades are arranged in an arc shape with both sides concave toward the middle, and the blades are inclined from the center of the impeller toward the outside thereof; a guide plate is arranged at the top of the blade, and the guide plate is inclined toward the curved side of the blade. The present invention arranges the blades in an arc shape and the guide plate at the top of the blade, so that during the centrifugal ejection of the shot, the shot and the blade are in contact for a long time, and the blade has a larger thrust action area on the shot, which ultimately makes the shot ejection speed faster; at the same time, the guide plate guides the initial direction of the shot leaving the blade, so that the shot is ejected in a concentrated manner.

[0004] However, the existing high-efficiency shot blasting machine will generate large vibrations during the shot blasting process, which is likely to produce large vibration noise due to the excessive vibration of the shot blasting machine, thereby affecting the surrounding environment. If the noise is too loud, it will also cause great harm to the human body and will also affect the service life of the entire machine body. In order to reduce the adverse hazards of vibration noise, the present invention proposes a high-efficiency shot blasting machine to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-efficiency shot blasting machine.

On both inner walls of the shock-absorbing cavity, there are provided movable grooves. An activity rod is movably installed in the movable groove, and one end of the activity rod movably extends into the shock-absorbing cavity and is fixedly connected with the sliding seat. A first spring sleeved on the activity rod is fixedly connected between the outer side of the sliding seat and the side wall of the shock-absorbing cavity;

[0009] On the top inner wall of the shock-absorbing cavity, there is fixedly connected with an arched shock-absorbing steel bar. The two ends of the bottom of the arched shock-absorbing steel bar are respectively rotatably connected with sliding blocks. On the top of the shock-absorbing connecting plate, there is provided a sliding groove, and both sliding blocks are slidably installed in the sliding groove. A second spring is also fixedly connected between the two sliding blocks.

[0010] Preferably, a shock-absorbing airbag is also fixedly connected between the shock-absorbing connecting plate and the bottom inner wall of the shock-absorbing cavity.

[0011] Preferably, the two rotating frames as a whole are in an outer "eight" shape structure.

[0017] 2. In the present invention, even when the entire shot blasting machine generates a large vibration during the shot blasting process, the main body of the shot blasting machine will move downward to reduce shock, and then the first spring, the shock-absorbing airbag, the arched shock-absorbing steel bar and the deformation of the second spring can greatly reduce the vibration generated by the shot blasting machine during the shot blasting process; in this way, the vibration is reduced, and the noise generated by the excessive vibration is relatively reduced, avoiding the disadvantage of the existing high-efficiency shot blasting machine generating a large vibration noise due to excessive vibration during the shot blasting process, thereby helping to reduce the harm caused by the vibration noise to the human body, and also greatly ensuring the service life of the entire shot blasting machine.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-3 A high-efficiency shot blasting machine comprises a shot blasting machine body 1, a shot inlet pipe 101 is arranged on the left side of the shot blasting machine body 1, a shot dividing wheel 102 and a shot blasting blade 103 are arranged in the shot blasting machine body 1, and a directional sleeve 104 is arranged on the left outer side of the shot dividing wheel 102, a buffer support 3 is arranged below the shot blasting machine body 1, a shock absorbing cavity 300 is arranged on the buffer support 3, a shock absorbing connecting plate 301 is movably installed in the shock absorbing cavity 300, and mounting frames 2 are fixedly connected to both sides of the bottom of the shot blasting machine body 1, and the bottom end of the mounting frame 2 movably penetrates into the shock absorbing cavity 300 and is fixedly connected to the shock absorbing connecting plate 301;

[0024] The bottom sides of the shock-absorbing connecting plate 301 are rotatably connected with rotating frames 302 respectively, the bottom end of the rotating frame 302 is rotatably connected with a slide seat 303, and the bottom of the slide seat 303 is slidably installed on the bottom inner wall of the shock-absorbing chamber 300, and movable grooves 306 are provided on the inner walls of both sides of the shock-absorbing chamber 300, and a movable rod 305 is movably installed in the movable groove 306, and one end of the movable rod 305 is movably extended into the shock-absorbing chamber 300 and fixedly connected with the slide seat 303, and a first spring 304 sleeved on the movable rod 305 is fixedly connected between the outer side of the slide seat 303 and the side wall of the shock-absorbing chamber 300;

[0025] An arched shock-absorbing steel bar 307 is fixedly connected to the inner wall of the top of the shock-absorbing chamber 300, and sliding blocks 308 are rotatably connected to the bottom ends of the arched shock-absorbing steel bar 307, and a sliding groove 310 is provided on the top of the shock-absorbing connecting plate 301, and two sliding blocks 308 are slidably installed in the sliding groove 310, and a second spring 309 is fixedly connected between the two sliding blocks 308. The present invention can greatly reduce the vibration generated by the shot blasting machine during the shot blasting process, and the reduced vibration also relatively reduces the noise generated by excessive vibration, avoiding the disadvantage of the existing high-efficiency shot blasting machine generating large vibration noise due to excessive vibration during the shot blasting process, thereby helping to reduce the harm caused by vibration noise to the human body, and also greatly guarantees the service life of the entire shot blasting machine.

[0026] In this example, a shock-absorbing airbag 311 is fixedly connected between the shock-absorbing connecting plate 301 and the bottom inner wall of the shock-absorbing cavity 300; the two rotating frames 302 are in an outer "eight" shape as a whole.

[0027] In this example, a first slider 312 is provided at the bottom of the sliding seat 303, first sliding grooves are provided on both sides of the bottom inner wall of the shock-absorbing chamber 300, and the first slider 312 is slidably installed in the first sliding groove; second sliders 313 are provided on both sides of the shock-absorbing connecting plate 301, second sliding grooves are provided on both sides of the inner walls of the shock-absorbing chamber 300, and the second slider 313 is slidably installed in the second sliding grooves.

[0028] In this example, the shot-distributing wheel 102 , the shot-blasting blades 103 and the directional sleeve 104 are all precision-casted from high-chromium wear-resistant materials, and the weight difference of each shot-blasting blade 103 is less than 2 grams.

[0029] In a high-efficiency shot blasting machine of the present invention, since the shot-splitting wheel 102, the shot-blasting blades 103 and the directional sleeve 104 are all precision-casted from high-chromium wear-resistant materials, and the weight difference of each shot-blasting blade 103 is controlled within 2 grams, it is beneficial to reduce the vibration caused by the difference between the shot-blasting blades 103, effectively reduce the noise during the operation of the shot blasting machine, and extend the life of the wearing parts; and even when the entire shot blasting machine generates a large vibration during the shot blasting process, the shot blasting machine body 1 can be made to move downward for shock absorption, and when the shot blasting machine body 1 moves downward, the shock-absorbing connecting plate 301 moves downward for shock absorption through the mounting frame 2, and when the shock-absorbing connecting plate 301 moves downward, the two slide seats 303 at the bottom ends of the two rotating frames 302 are moved away from each other and compress the first spring 304, and at the same time, when the shock-absorbing connecting plate 301 moves downward, it also compresses and buffers the shock-absorbing airbag 311, which In this way, the compression deformation of the first spring 304 and the shock-absorbing airbag 311 can play a role in buffering and dissipating energy; and, when the shock-absorbing connecting plate 301 moves downward, the bottom ends of the arched shock-absorbing steel bar 307 are also caused to shrink and deform inward. At the same time, when the bottom ends of the arched shock-absorbing steel bar 307 shrink inward, they also drive the two sliding blocks 308 to move toward each other and squeeze the second spring 309. In this way, through the deformation of the arched shock-absorbing steel bar 307 itself and the deformation of the second spring 309, a part of the excessive vibration force can be further consumed; ultimately, the vibration is reduced, and the noise generated by the excessive vibration is relatively reduced, avoiding the disadvantage of the existing high-efficiency shot blasting machine generating large vibration noise due to excessive vibration during the shot blasting process, which is beneficial to reduce the harm caused by vibration noise to the human body, and also greatly guarantees the service life of the entire shot blasting machine.
