Technical Field

[0001] The utility model relates to the field of shot blasting cleaning, in particular to a catenary type shot blasting cleaning machine which can prevent projectiles from flying. Background Art

[0002] Shot blasting uses the centrifugal force of the impeller on the shot blasting machine when it rotates at high speed to shoot the abrasive at a high linear velocity to the surface of the steel being processed, producing a striking and grinding effect, removing the oxide scale and rust on the steel surface, and creating a certain degree of roughness; the catenary shot blasting machine is a common shot blasting machine. It is suitable for cleaning or strengthening the surface of batches of medium and small castings and forgings and heat-treated parts, and is particularly suitable for industries such as automobiles, tractors, diesel engines, motors, and valves.

An adjustment mounting assembly is fixedly installed on the top wall of the shot blasting chamber. The adjustment mounting assembly includes a screw, one end of the screw is rotatably connected to the inner wall of the shot blasting chamber through a bearing, and the other end is fixedly installed on the output end of the first motor. Limit rods are fixedly installed on both sides of the screw, and the two ends of the limit rods are respectively fixedly connected to the inner wall of the shot blasting chamber, and the screw and the limit rod sleeve are provided with adjustment blocks.

[0004] Existing equipment blocks the impact force of the shot by setting an oblique buffer plate, which eventually causes the shot to fall. However, the oblique buffer plate is rigidly set in a fixed position. Because the rigid buffer directly bears the impact force, the material requirements are high, which leads to increased maintenance and production costs.

[0005] For this reason, it is necessary to provide a catenary type shot blasting machine that prevents projectiles from flying to solve the above-mentioned technical problems. Utility Model Content

This solves the problem that the existing equipment blocks the power of the shot blasting that comes into contact with it by setting an oblique buffer plate, thereby finally causing the shot blasting to fall. However, the oblique buffer plate is rigidly arranged in a fixed position. Since the rigid buffer directly bears the impact force, the material requirements are relatively high.

[0023] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a catenary shot blasting machine for preventing projectiles from flying provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the structure inside the protective box is shown; Figure 3 for Figure 1 The structural diagram of the back of the protective box is shown; Figure 4 for Figure 1 The schematic diagram of the structure inside the shot blasting box is shown; Figure 5 for Figure 1 The structural diagram of structure A shown in the figure includes a catenary shot blasting cleaning machine for preventing projectiles from flying, including a protective box 1, a shot blasting structure 2 is provided on both sides of the protective box 1, a plurality of anti-flying flaps 3 are symmetrically provided inside the protective box 1, a debris removal structure 4 is provided at the bottom end of the protective box 1, and a recovery structure 5 is provided on the top of the debris removal structure 4;

[0025] The impurity removal structure 4 includes a screen plate 401, and two sliders 402 are symmetrically provided at both ends of the screen plate 401. The ends of the four sliders 402 that are away from each other are slidably set in the corresponding slide grooves 403 opened inside the protective box 1, and the tops of the four sliders 402 are installed in the corresponding slide grooves 403 through springs 404.

[0026] It should be noted that the falling shot blasting and rust debris continuously collide with the screen plate 401, causing the four sliders 402 on the screen plate 401 to move downward along the corresponding slide grooves 403 and stretch the connected springs 404. When the elastic limit of the four springs 404 is reached, the four springs 404 pull the screen plate 401 upward, and the reciprocating operation achieves the purpose of screening and removing rust debris.

[0027] In the specific implementation process, refer to Figure 2 and Figure 5 As shown, a debris collection box 405 is plugged into the front of the protective box body 1 and located at the bottom of the screen plate 401.

[0028] It should be noted that the screen plate 401 reciprocates to separate the shot blasting from the rust and debris. The rust and debris fall into the debris collection box 405 , and the shot blasting stays on the top of the screen plate 401 .

[0029] In the specific implementation process, refer to Figure 2 and Figure 3 As shown, the shot blasting structure 2 includes a shot blasting impeller box 201 symmetrically fixed on both sides of the protective box body 1 and located on top of several anti-flying flaps 3. The interiors of the two shot blasting impeller boxes 201 are both provided with shot blasting impellers 202 that are rotated by drive shafts. The rear ends of the two drive shafts extend through the corresponding shot blasting impeller boxes 201 and are plugged with motors 207. The front ends of the two motors 207 are fixedly set on the corresponding shot blasting impeller boxes 201.

[0030] It should be noted that the motor 207 controls the shot blasting impeller 202 outside the drive shaft to rotate at high speed, accelerates the shot blasting, and then throws it through the corresponding shot blasting port 203 to perform shot blasting and rust removal.

[0031] In the specific implementation process, refer to Figure 1 and Figure 4 As shown, the two shot blasting impeller boxes 201 are each provided with a shot blasting port 203 at one end close to each other, and the tops of the two protective box bodies 1 are both connected with a feeding pipe 204. The tops of the two feeding pipes 204 pass through the shot blasting box 205 and are connected with the same feeding pump 206. The feeding pump 206 is fixedly set at the bottom end of the shot blasting box 205, and the shot blasting box 205 is fixedly set on the protective box body 1.

[0032] It should be noted that the feeding pump 206 generates suction to transport the shot in the shot blasting box 205 to the two feeding pipes 204 until it flows into the corresponding shot blasting impeller box 201, continuously providing shot for subsequent shot blasting.

[0033] In the specific implementation process, refer to Figure 1 and Figure 3 As shown, the recovery structure 5 includes a recovery pipe 501 that passes through and is plugged into the rear end of the protective box 1. One end of the recovery pipe 501 is fixedly set on the top of the screen plate 401, and the other end of the recovery pipe 501 is plugged into a recovery pump 502. The recovery pump 502 is fixedly set on the top of the shot blasting box 205.

[0034] It should be noted that the recovery pump 502 generates suction to transport the shot blasting located on the top of the screen plate 401 to the inside of the shot blasting box 205 through the recovery pipe 501 for secondary use.

[0035] In the specific implementation process, refer to Figure 1 As shown, a protection box door 6 is rotatably provided on the front of the protection box body 1 .

[0036] The working principle of the catenary shot blasting machine for preventing projectiles from flying provided by the utility model is as follows:

[0037] When in use, the material to be shot blasted is suspended inside the protective box 1 by an iron chain, the protective box door 6 is closed, and then the feeding pump 206 generates suction to transport the shot inside the shot blasting box 205 to the two feeding pipes 204 until it flows into the corresponding shot blasting impeller box 201. The motor 207 controls the shot blasting impeller 202 outside the drive shaft to rotate at high speed, accelerates the shot, and then throws it out through the corresponding shot blasting port 203 to perform shot blasting and rust removal. After the shot hits the material to be shot blasted, it returns and hits the corresponding anti-flying flap 3, and the anti-flying flap 3 is obtained. The impact force is converted into a rotational force to achieve flexible buffering behavior. The falling shot blasting and rust debris continuously collide with the screen plate 401, causing the four sliders 402 on the screen plate 401 to move downward along the corresponding slide grooves 403 and stretch the connected springs 404. When the elastic limit of the four springs 404 is reached, the four springs 404 pull the screen plate 401 upward, and the reciprocating operation is carried out to achieve the purpose of screening and removing rust debris. The recovery pump 502 generates suction to transport the shot blasting located on the top of the screen plate 401 through the recovery pipe 501 to the inside of the shot blasting box 205 for secondary use.
