Description

Technical Field

[0001] The present invention relates to the field of rust removal equipment, and particularly to a rust removal device. Background Art

[0002] Currently, the rust removal methods in the market can mainly be divided into shot blasting rust removal, sand blasting rust removal, and non-pickling wire drawing rust removal.

[0003] Shot blasting rust removal mainly uses the high-speed operation of mechanical equipment to throw steel shots of a certain particle size out by the centrifugal force of the shot blasting head mechanism. The thrown steel shots collide violently with the object to be rust-removed, thereby achieving the removal of the rust on the object to be rust-removed. The shot blasting rust removal equipment mainly consists of a shot blaster, a wear-resistant rubber belt, a screw conveyor, a hoist, a separator, a feeding conveyor, a dust collector, and an electrical assembly. Sand blasting rust removal is a rust removal method that uses high-pressure air to carry out quartz sand and spray it onto the surface of the component. A complete suction-type dry sand blaster generally consists of six systems, namely a structure system, a medium power system, a pipeline system, a dust removal system, a control system, and an auxiliary system. Non-pickling wire drawing rust removal is mainly for the rust removal of wire rods. The non-pickling shelling rust remover mainly consists of a gearbox five-wheel shelling mechanism, an adjustable cross parabolic wire brush wheel, a fully enclosed rust removal chamber, a forced lubrication device, a wire drawing die holder, and an electrical control system. Thus, it can be seen that whether it is a shot blasting rust remover, a sand blasting rust remover, or a non-pickling wire drawing equipment, their rust removal processes all require a combination of multiple devices to form a complete rust removal production line, with the equipment being bulky and occupying a lot of space.

[0064] For ease of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0065] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be intermediate elements present at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are only for the purpose of illustration.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0067] Such as Figures 1 - 23As shown in the figure, the technical solution adopted by the present invention is a rust removal device, which includes a driving mechanism and a plurality of rust removal units 1 arranged side by side. Each rust removal unit 1 includes a bullet head 12 and a rust removal unit body 11 connected to the bullet head 12. One end of the bullet head 12 forms a knocking part 1200, and the bullet head 12 reciprocates relative to the rust removal unit body 11 under the drive of the driving mechanism. One end of the bullet head 12 is connected to the rust removal unit body 11, and the other end is a free end. The object to be rust-removed is close to the free end of the bullet head 12. When the bullet head 12 reciprocates, the free end of the bullet head 12 knocks on the object to be rust-removed (the material 800 is generally a metal plate, such as a steel plate, an iron plate, etc.), and the rust on the surface of the object to be rust-removed is removed by knocking and vibration. At the moment when the bullet head 12 knocks on the material 800, the material 800 is fixed by an external force, and the overall vibration amplitude of the material 800 is small. Therefore, compared with the existing rust removal devices, the noise generated is small. Since the bullet heads 12 are evenly distributed, the acting forces during knocking are also evenly distributed, and the rust removal effect is relatively stable.

[0068] In a preferred embodiment, the rust removal device includes a plurality of rust removal modules that move independently of each other, and each rust removal module includes a plurality of rust removal units 1 that move synchronously. During production, the corresponding number of rust removal modules can be integrated together, and there is no need to install each individual rust removal module separately, which is convenient for production and installation. During use, if a certain module is damaged, it is convenient to disassemble and replace, and the maintenance is more convenient.

[0069] In a preferred embodiment, the rust removal device further includes a mounting bracket 40, and each rust removal module further includes a module bracket 20. The rust removal unit 1 is fixed on the module bracket 20. The module bracket 20 is movably connected to the mounting bracket 40, and the module bracket 20 can reciprocate relative to the mounting bracket 40 along the movement direction of the bullet head 12. During use, the module bracket 20 is adjusted according to the thickness of the material 800 to make the distance between the rust removal module and the material 800 appropriate.

[0070] In a preferred embodiment, each rust removal module further includes a positioning member 30. The positioning member 30 is fixed on the module bracket 20, and an adjusting spring is further provided between the module bracket 20 and the mounting bracket 40.

[0071] In a preferred embodiment, the positioning member 30 includes a positioning roller 3010, and the positioning roller 3010 is arranged on the feeding side of the rust removal module. During operation, the positioning wheel presses on the object to be rust-removed, and when the bullet head 12 reciprocates to the highest point, there is a certain distance between it and the object to be rust-removed.

[0072] In a preferred embodiment, the mounting bracket 40 includes a suspension beam 401, at least two support columns 402, a connecting column 403, and a tie rod 404. At least two support columns 402 are fixedly connected to the suspension beam 401 and protrude upward relative to the suspension beam 401. The connecting column 403 is connected to the suspension beam 401 and is located between the two support columns 402. The first end of the tie rod 404 is connected to the support column 402, and the second end is connected to the connecting column 403, and the first end of the tie rod 404 is higher than the second end. Since most of the components of the entire rust removal device are assembled in the middle of the mounting bracket 40, the gravity is too large. Especially when there are more rust removal modules, the gravity of the rust removal module itself, the gravity of the material 800 during operation, and the force applied by the power device are concentrated together, which may be difficult for an ordinary mounting bracket 40 to bear. The mounting bracket 40 adopted in the present invention can cleverly transfer part of the force in the middle to both sides, reduce the burden in the middle, and make the overall structure more stable.

[0073] In a further preferred embodiment, the mounting bracket 40 includes a suspension beam 401, two support columns 402, two connecting columns 403, two tie rods 404, and a connecting rod 405. The two support columns 402 are respectively fixed at both ends of the suspension beam 401. The two connecting columns 403 are fixed on the suspension beam 401 and are located between the two support columns 402. The two connecting columns 403 are arranged at intervals. The two ends of the two tie rods 404 are respectively connected to the corresponding connecting column 403 and support column 402. The two ends of the connecting rod 405 are connected to the two connecting columns 403. The setting of the connecting rod 405 makes the integrity of the mounting bracket 40 higher and the structure more firm.

[0074] In another preferred embodiment, the rust removal device further includes a mounting bracket 40 and a support bracket 50. A plurality of rust removal units 1 are installed on the mounting bracket 40, and the mounting bracket 40 is installed on the support bracket 50. Both ends of the mounting bracket 40 are connected to the support bracket 50, and part of the gravity of the rust removal module itself, the gravity of the material 800 during operation, and the force applied by the power device are transferred to the support bracket 50. A lifting assembly 60 is provided between the mounting bracket 40 and the support bracket 50. The lifting assembly 60 is used to drive the mounting bracket 40 to lift relative to the support bracket 50; the lifting assembly 60 can make the mounting bracket 40 drive the components installed on its upper part to move up and down, so as to adjust the height of the rust removal module, so that it can be applied in different scenarios, and rust removal devices can be used for materials 800 with different thicknesses.

[0075] In a preferred embodiment, the rust removal device includes a first rust removal array 100 and a second rust removal array 200. An inlet channel is formed between the first rust removal array and the second rust removal array 200. Both the first rust removal array 100 and the second rust removal array 200 include a plurality of rust removal units 1 arranged side by side. The bullet heads 12 of the first rust removal array 100 face the opposite direction to those of the second rust removal array 200. The material 800 passes through the inlet channel. The first rust removal array 100 and the second rust removal array 200 strike different surfaces of the material 800 respectively, achieving simultaneous double-sided rust removal with higher efficiency. In the feeding direction of the rust removal device, the first rust removal array 100 and the second rust removal array 200 are arranged facing each other or offset. Preferably, they are arranged in an offset manner. The bullet head 12 of the present invention strikes the material 800, generating small-area and large-amplitude vibrations, thereby removing the rust on its surface. If they are arranged facing each other, the two sides of the material 800 are stressed simultaneously, which will inevitably cause part of the force to be offset, and the rust removal effect is relatively poor. The offset arrangement can exactly avoid this problem and can also achieve the effect of double-sided rust removal.

[0076] In a preferred embodiment, the rust removal device includes a front rust removal array 300 and a rear rust removal array 400. The front rust removal array 300 and the rear rust removal array 400 are arranged at intervals along the feeding direction of the rust removal device. And the rear rust removal array 400 is arranged on the discharge side of the front rust removal array 300. A rust detection device 500 is also arranged between the front rust removal array 300 and the rear rust removal array 400. The rust detection device 500 detects the material 800 coming out of the front rust removal array 300. If it detects that there is still rust on some parts, the rear rust removal array 400 will make supplementary strikes according to the detection results. The bullet heads 12 on the rear rust removal array 400 selectively strike the positions with rust. This can not only ensure the rust removal effect but also avoid the problem of excessive roughness of the material 800 caused by over-rust removal. In a preferred embodiment, the rust detection device 500 includes a detection bracket and a camera installed on the detection bracket. The camera is connected to the controller of the rust removal device. The surface of the material 800 is photographed by the camera, and then rust detection is carried out by means of image recognition. In this embodiment, the detection bracket is installed with two rows of cameras, upper and lower, for photographing and rust detection of the upper surface and the lower surface of the material 800 respectively. In other embodiments, the rust detection device 500 can also detect rust through ultrasonic probes.

[0077] In a preferred embodiment, the post-rust-removing array 400 includes a plurality of rust-removing modules that move independently of each other. Each rust-removing module includes a plurality of rust-removing units 1 that move synchronously. The rust-removing device further includes a mounting bracket 40. Each rust-removing module further includes a module bracket 20. The rust-removing unit 1 is fixed on the module bracket 20. A lifting drive device is provided between the module bracket 20 and the mounting bracket 40. The lifting drive device drives the module bracket 20 to reciprocate relative to the mounting bracket 40 along the movement direction of the bullet head 12. Specifically, the structure of the post-rust-removing array 400 is the same as that of the pre-rust-removing array 300. Since the function of the post-rust-removing array 400 is to supplement rust removal and remove the rust that has not been completely removed by the pre-rust-removing array 300, its workload is relatively small, and the post-rust-removing array 400 can also be set according to the actual situation.

[0078] In a preferred embodiment, a rust detection device 500 is further provided on the discharge side of the post-rust-removing array 400 to detect the qualified situation of rust removal for products with high requirements for rust-removing quality.

[0079] In a preferred embodiment, at least some of the rust-removing units 1 are distributed in multiple rows and columns, and in the direction perpendicular to the feeding direction of the rust-removing device, the centers of the knocking parts 1200 of at least some of the rust-removing units 1 in different rows are offset, that is, the projections of the multiple bullet heads 12 in the direction perpendicular to the feeding direction of the rust-removing device are different. After the material passes through the rust-removing station, the points knocked by the bullet heads 12 on the rust-removing plate are connected into a sheet, and the rust-removing effect is better.

[0080] In a preferred embodiment, on the knocking surface of the rust-removing device, the centers of the knocking parts 1200 of at least some of the rust-removing units 1 are distributed in a parallelogram dot matrix, and the connection line of the centers of the knocking parts 1200 of the rust-removing units 1 in the same column is inclined relative to the feeding direction of the rust-removing device. The adjacent bullet heads 12 are staggered to avoid leaving blind spots on the plate to be rust-removed that cannot be knocked.

[0081] In a preferred embodiment, at least some of the rust-removing units 1 are arranged to form a striking area, and a dust-proof curtain (not shown) is provided on the feeding side and / or the discharge side of the striking area. The lower end of the dust-proof curtain contacts the plate to be rust-removed. During the knocking rust-removing process, a large amount of dust will float into the air. The dust-proof curtain separates the dust inside the dust-proof curtain and reduces the pollution of the air outside the dust-proof curtain. Further, the dust-proof curtain is a hard curtain, and a soft edge is provided at its lower part. The edge contacts the object to be rust-removed and can play a role in collecting debris. Specifically, the soft edge is a brush or a high-molecular soft material.

[0082] In a preferred embodiment, a waste collection device is provided on the discharge side of the rust-removing unit 1 to remove the debris knocked off.

[0083] In a preferred embodiment, the rust removal unit body 11 further includes a dust suction pipe 16, the opening of the dust suction pipe 16 is arranged close to the knocking part 1200, and is used for removing the slag knocked off.

[0084] In a preferred embodiment, a spiral waste collection brush 160 and a dust suction device are arranged on the discharge side of the rust removal unit 1. The central axis of the waste collection brush 160 is arranged along the length direction of the rust removal unit, and the dust suction port of the dust suction device is arranged close to the end of the waste collection brush 160. Specifically, the waste collection brush 160 is connected to a power mechanism, and the power mechanism drives the waste collection brush 160 to rotate. The spiral waste collection brush 160 can collect the slag on the plate to be rust removed to one side of the plate. The dust suction device is used for dust removal, reducing air pollution, and can also collect the waste into a waste bin.

[0085] In a preferred embodiment, the rust removal unit body 11 includes an air chamber 10, the bullet head 12 is movably installed in the air chamber 10, the driving mechanism includes an air distribution mechanism 31, and the air distribution mechanism 31 is communicated with the air chamber 10 for introducing compressed air into the air chamber 10 to drive the bullet head 12 to reciprocate relative to the air chamber 10. Specifically, the rust removal device includes a plurality of air distribution mechanisms 31, and each air distribution mechanism 31 is communicated with a plurality of rust removal units 1 through pipelines. In another preferred embodiment, the rust removal device includes a plurality of rust removal modules that move independently of each other. Each rust removal module includes a plurality of rust removal units 1 that move synchronously, and each rust removal module is connected to an air distribution mechanism 31.

[0086] In a preferred embodiment, the rust removal mechanism mainly includes a bullet head 12, an air chamber 10, a buffer chamber 103, an air distribution mechanism 31, a shock absorption device, a rust block recovery device, and a traveling driving mechanism 15.

[0087] In a further preferred embodiment, the air chamber 10 includes two parts, a guiding through hole 101 and a piston chamber 102 below the guiding through hole 101. The buffer chamber 103 is a part of the piston chamber 101. The space formed by the end of the bullet head 12 located in the piston chamber 101 and the side wall of the piston chamber 101 is the buffer chamber 103, and the size of the space of the buffer chamber 103 changes with the movement of the bullet head 12. The bullet head 12 is installed in the guiding through hole 101 in a liftable manner, and the side wall of the bullet head 12 fits with the inner wall of the guiding through hole 101 so that the piston chamber 102 is not communicated with the outside atmosphere. A buffer chamber 103 is arranged at the end of the piston chamber 102 far from the guiding through hole 101. A pressurizing station 104 is arranged in the piston chamber 102. A vertical air passage 107 is arranged in the side wall of the piston chamber 102. One port of the air passage 107 is communicated with the buffer chamber 103, and the other port of the air passage 107 is communicated with the pressurizing station 104. A pressure relief station 105 is arranged in the guiding through hole 101, and the pressure relief station 105 is communicated with the atmospheric pressure; the pressurizing station 104 and the pressure relief station 105 are annular grooves.

[0088] In a further preferred embodiment, the bullet head 12 includes a bullet head inner cavity 120. A knocking portion 1200 for removing rust is provided at the top end of the bullet head 12. Air holes are formed in the side wall of the bullet head 12, and the air holes may include a first air hole 121 and a second air hole 122. When the bullet head 12 is not actuated, the second air hole 122 corresponds to the pressurizing station 104, while the first air hole 121 is closed by the side wall of the guiding through hole 101 within the guiding through hole 101, so that the bullet head inner cavity 120, the piston cavity 102 are isolated from the external atmosphere. Therefore, when the air distribution mechanism 31 jets air to pressurize the buffer cavity 103, the gas passes from the buffer cavity 103 through the air passage 107 of the piston cavity 102 into the pressurizing station 104, and the gas at the pressurizing station 104 enters the bullet head inner cavity 120 from the second air hole 122, making the air pressure in the bullet head inner cavity 120 equal to that of the piston cavity 102. At this time, there is a pressure difference between the piston cavity 102 and the external atmospheric pressure, and thus the bullet head 12 is pushed towards the guiding through hole 101; the bullet head 12 is pushed by the air pressure and moves away from the piston cavity 102 until the first air hole 121 corresponds to the pressure relief station 105, so that the gas in the bullet head inner cavity 120 is discharged into the external atmosphere; and because the second air hole 122 has left the pressurizing station 104 and is closed by the inner wall of the guiding through hole 101, a certain pressure is maintained in the piston cavity 102. Therefore, when the bullet head 12 rebounds after knocking the object to be rust-removed, the piston cavity 102 can play the role of an air cushion to prevent the bullet head 12 from hitting the bottom of the buffer cavity 103 when rebounding. In order to ensure that the bullet head 12 can return to its initial position every time it rebounds, that is, the position where the first air hole 121 corresponds to the pressurizing station 104, and at the same time avoid the rebounding bullet head 12 from hitting the buffer cavity 103, a shock-absorbing spring facing the bullet head 12 is provided in the buffer cavity 103. When the bullet head 12 rebounds, it hits the shock-absorbing spring and decelerates, so that the second air hole 122 can correspond to the pressurizing station 104.

[0089] In a further preferred embodiment, the piston cavity 102 is wide and the guiding through hole 101 is narrow, and the cross-section is similar to a "convex" shape. The piston cavity 102 and the guiding through hole 101 are connected by a connecting portion, and a second limiting portion 106 is formed at the connecting portion. A flank is provided at the lower part of the bullet head 12, and this flank is the first limiting portion 123. When the bullet head extends to the longest state, the second limiting portion 106 and the first limiting portion 123 are in contact, resulting in the bullet head 12 being unable to extend further. At this time, the knocking portion 1200 of the bullet head 12 has extended out of the orifice of the air cavity 10 and can reach the object to be rust-removed for rust removal. The purpose of the setting is to prevent the bullet head 12 from slipping off the guiding through hole 101.

[0090] In the prior art, the gas distribution mechanism 31 is arranged on one side of the pressurizing station 104, and the gas is directly sprayed into the pressurizing station 104. The disadvantage of this is that the high-speed air flow will disturb the movement of the warhead 12, resulting in a decrease in the speed of the warhead 12, an increase in the entire cycle of rebound after ejection, a decrease in the number of actuations of the warhead 12 per unit time, and an inability to achieve the ideal rust removal effect. Therefore, in the present invention, the gas distribution mechanism 31 is arranged below the buffer chamber 103, and the connection lines of the buffer chamber 103, the piston chamber 102, and the guiding through hole 101 are in a straight line (their central axes are on the same straight line), and the air outlet of the gas distribution mechanism 31 is offset from the air inlet of the air passage 107, so that the buffer chamber 103 plays a role of primary buffering, avoiding directly disturbing the warhead 12 by the kinetic energy of the ejected gas itself, but driving the warhead 12 through air pressure, which is beneficial to increasing the number of actuations of the warhead 12 per unit time.

[0091] In a preferred embodiment, the rust removal device further includes a linear motion driving mechanism capable of driving the air chamber 10 to approach or move away from the object to be rust-removed; it further includes a shock-absorbing spring 14, and the shock-absorbing spring 14 is sleeved outside the air chamber 10; the dust suction pipe 16 includes a rust block recovery port disposed on one side of the warhead 12, and the dust suction pipe 16 is communicated with the rust block recovery port.

[0092] In a preferred embodiment, the rust removal unit body includes a first body 111 and a second body 112. The first body 111 and the second body 112 are connected. A pressurizing station 104 is formed on the first body 111, a pressure relief station 105 is formed on the second body 112, an air chamber 10 is formed between the first body 111 and the second body 112, and a warhead outlet for the knocking part 1200 of the warhead 12 to pass through is further formed on the second body 112. When the warhead 12 is in the extended state, the air chamber 10 is communicated with the pressure relief station 105, and the air chamber 10 is not communicated with the pressurizing station 104. When the warhead 12 is in the retracted state, the air chamber 10 is not communicated with the pressure relief station 105, and the air chamber 10 is communicated with the pressurizing station 104.

[0093] In a preferred embodiment, the rust removal unit body includes a first body 111 and a second body 112, and the first body 111 and the second body 112 are connected. Specifically, the first body 111 and the second body 112 are fixedly connected by clamping or fixedly connected by bolts. A piston chamber 102, a buffer chamber 103, and an air passage 107 are formed in the first body 111. The buffer chamber 103 is located above the piston chamber 102 and is on the same straight line as the piston chamber 102. Further, the buffer chamber 103 is a part of the piston chamber 102, and the chamber formed by the connecting end of the bullet head (i.e., the end located in the piston chamber 102) and a part of the side wall of the piston chamber 102 is the buffer chamber 103. A pressurizing station 104 is formed on the side wall of the piston chamber 102, and the pressurizing station 104 is connected to the buffer chamber 103 through the air passage 107. The air distribution mechanism 31 introduces high-pressure gas into the buffer chamber 103 and then into the pressurizing station 104. A guiding through hole 101 is formed on the second body 112, and a pressure relief station 105 is provided on the side wall of the guiding through hole 101. The knocking part 1200 of the bullet head can pass through the guiding through hole 101 and can extend out of the guiding through hole 101. A bullet head inner cavity 120, a first air hole 121, and a second air hole 122 are formed on the bullet head 12, and both the first air hole 121 and the second air hole 122 are connected to the bullet head inner cavity 120. When the bullet head 12 is in the retracted state, the second air hole 122 is communicated with the pressurizing station 104, and the first air hole 121 is blocked by the side wall of the guiding through hole 101. The high-pressure air flow passes through the buffer chamber 103, the pressurizing station 104, and the second air hole 122 and enters the bullet head inner cavity 120, so that the pressures in the bullet head inner cavity 120 and the buffer chamber 103 are balanced and higher than the atmospheric pressure. When the pressure becomes larger and larger, the bullet head 12 can be pressed downward to make the bullet head 12 extend out and knock on the material 800. When the bullet head 12 is in the extended state, the first air hole 121 is connected to the pressure relief station 105, and the second air hole 122 is blocked by the side wall of the piston chamber 102. After the first air hole 121 is communicated with the pressure relief station 105 on the second body 112, the high pressure in the bullet head inner cavity 120 is discharged from the pressure relief station 105. After the bullet head 12 knocks on the plate to be rust-removed, a very strong rebounding force will also be formed, causing the bullet head to quickly bounce back to its original position. Since the pressure in the buffer chamber 103 still exists, the gas in the buffer chamber 103 forms an air cushion, which can buffer the rebounding force of the bullet head 12, reduce or even avoid the impact between the connecting end of the bullet head 12 and the piston chamber 102, reduce wear, and extend the service life of the rust removal device. The specific gravity of the material of the second body 112 is lower than that of the material of the first body 111. Dividing the rust removal unit body 11 into the first body 111 and the second body 112 can reduce the weight of the rust removal device and save costs without affecting the performance of the rust removal device. Specifically, the first body 111 is made of stainless steel, and the second body 112 is made of materials such as plastic and aluminum alloy.The first body 111 includes a piston cylinder 1111, an inner cover 1113 and an outer cover 1112. The piston chamber 102 is located within the piston cylinder 1111. The bullet head 12 passes through the piston chamber 102, and the other end of the bullet head 12 is stuck within the piston chamber 102. The outer cover 1112 is fixed to the piston cylinder 1111. The buffer chamber 103 is formed by the outer cover 1112, the inner cover 1113 and the piston cylinder 1111. The inner cover 1113 is located between the piston chamber 102 and the buffer chamber 103. When the bullet head 12 extends, the bullet head 12 and the inner cover 1113 seal the piston chamber 102, and the inner cover 1113 and the outer cover 1112 seal the buffer chamber 103. Gas is filled into the buffer chamber 103, and the gas enters the piston chamber 102 through the air passage, and then enters the inner cavity 120 of the bullet head. When the air pressure is large enough, the bullet head 12 is pressed out, and the bullet head 12 hits the material. After being impacted, the bullet head 12 resets, and the bullet head 12 presses the inner cover 1113 towards the buffer chamber 103. The gas in the buffer chamber 103 forms an air cushion to buffer the bullet head 12 and the inner cover 1113, reduce the impact force, and extend the service life.

[0094] In a further preferred embodiment, the first body 111 is made of a metal material, and the second body 112 is made of a plastic material. Specifically, the first body 111 is made of stainless steel, and the second body 112 is made of plastic, such as PC / SAN type, PC / PBT type, PC / PP type, etc. Further, the first body 111 includes a piston cylinder 1111, an inner cover 1113 and an outer cover 1112. Both ends of the piston cylinder 1111 are open. The bullet head 12 penetrates from the first end of the piston cylinder 1111 into the second end of the piston cylinder 1111, and the connecting end of the bullet head 12 is located within the piston cylinder 1111. The inner cover 1113 is fixed inside the first end of the piston cylinder 1111, and the outer cover 1112 covers the inner cover 1113 and is fixed outside the piston cylinder 1111.

[0095] In a preferred embodiment, at least part of the second bodies 112 of the rust removal unit 1 are connected to each other as a whole. This makes the structure more stable and can better resist the impact force formed during pressure relief. Further, all the second bodies 112 on each rust removal module are integrally cast. Each rust removal module includes 4*3 or 5*4 bullet heads 12, and each bullet head 12 is provided with a second body 112. Multiple second bodies 112 are cast into a whole.

[0096] In a preferred embodiment, the rust removal mechanism includes a rust removal mechanism body 111 and a bullet head 12. A piston chamber 102 and a buffer chamber 103 are provided inside the rust removal mechanism body 111. The first end of the bullet head 12 is located inside the piston chamber 102, and the second end forms a rust removal part that can extend out of the piston chamber 102. The rust removal part is used to remove rust from materials, rust the materials, or break the materials. An inner cover 1113 is provided between the piston chamber 102 and the buffer chamber 103. The inner cover 1113 separates the piston chamber 102 and the buffer chamber 103, and the inner cover 1113 can move inside the buffer chamber 103. When the bullet head 12 rebounds, it first collides with the inner cover 1113. There is high-pressure gas inside the buffer chamber 103. When the buffer part moves inside the buffer chamber 103, the high-pressure gas plays a buffering role, so that the bullet head 12 will not be damaged. The diameter of the buffer chamber 103 is larger than that of the piston chamber 102, and the piston chamber 102 and the buffer chamber 103 are coaxial. A step is formed between the piston chamber 102 and the buffer chamber 103. One end of the inner cover 1113 located in the buffer chamber 103 presses on this step. After the bullet head 12 collides with the inner cover 1113, the buffer chamber 103 can play a buffering role. A pressurizing station 104 and a pressure relief station 105 are provided on the rust removal mechanism body 111. When the bullet head 12 is in the retracted state, the piston chamber 102 and the pressure relief station 105 are not in communication, and the buffer chamber 103, the piston chamber 102, and the pressurizing station 104 are in communication with each other; high-pressure gas (of course, it can also be hydraulic pressure) first enters the buffer chamber 103, then enters the pressurizing station 104 from the air passage 107, and then enters the piston chamber 102 from the pressurizing station 104. When the pressure in the piston chamber 102 is high enough, the bullet head 12 can be pressed out of the piston chamber 102, so that the rust removal part of the bullet head 12 strikes the material, for rust removal, breaking the material, etc. When the bullet head 12 is in the extended state, the piston chamber 102 and the pressure relief station 105 are in communication, and the piston chamber 102 and the pressurizing station 104 are not in communication; after the piston chamber 102 and the pressure relief station 105 are in communication, the gas in the piston chamber 102 can be released. The air pressure in the piston chamber 102 decreases. Coupled with the resilience formed after the bullet head 12 collides with the material, the bullet head 12 rebounds quickly, and then a movement of extending again is carried out.

[0097] In a further preferred embodiment, a bullet head inner cavity 120, a first air hole 121, and a second air hole 122 are formed on the bullet head 12. Both the first air hole 121 and the second air hole 122 are connected to the bullet head inner cavity 120. The bullet head inner cavity 120 has an opening at the first end of the bullet head 12, so that the bullet head inner cavity 120 is connected to the piston chamber 102. High-pressure gas (of course, it can also be hydraulic pressure) first enters the buffer chamber 103, then enters the pressurizing station 104 from the air passage 107, and then enters the piston chamber 102 from the pressurizing station 104.

[0098] In a further preferred embodiment, the rust removal mechanism body further includes a piston cylinder 1111 and an outer cover 1112. The piston chamber 102 is located inside the piston cylinder 1111 and penetrates through both ends of the piston cylinder 1111. The buffer chamber 103 is located inside the outer cover 1112, and one end facing the piston chamber 102 is open. The inner cover 1113 seals both the piston chamber 102 and the buffer chamber 103 at the same time. The inner cover 1113 can not only seal the piston chamber 102, but also move inside the buffer chamber 103. Further, the first end of the inner cover 1113 cooperates with the piston chamber 102, and the second end of the inner cover 1113 cooperates with the buffer chamber 103.

[0099] In a further preferred embodiment, a pressing air groove 11130 is provided on the second end face of the inner cover 1113.

By providing the pressing air groove 11130, the inner cover 1113 can be tightly abutted against the end of the side wall of the piston chamber 102, and the sealing effect is better.

[0100] In a further preferred embodiment, an air passage 107 is formed on the side wall of the rust removal mechanism body. One end of the air passage 107 is communicated with the buffer chamber 103, and the other end is connected to the piston chamber 102.

[0101] In a further preferred embodiment, a first limiting portion 123 is formed at the first end of the bullet head 12.

A second limiting portion 106 cooperating with the first limiting portion 123 is provided on the side wall of the piston cylinder 1111. The diameter of the second limiting portion 106 matches the diameter of the bullet head 12. The pressurizing station 104 is located on the second limiting portion 106, and its opening faces the first limiting portion 123. Before the first beating of the material, there is no high-pressure gas in the buffer chamber 103 and the piston chamber 102. However, due to the self-gravity of the bullet head 12, the bullet head 12 is in a suspended state. When high-pressure gas is filled into the buffer chamber 103, the high-pressure gas applies pressure to the second limiting portion 106 through the pressurizing station 104, forcing the bullet head 12 to retract into the piston chamber 102 until the pressurizing station 104 is communicated with the buffer chamber 103.

[0102] In a further preferred embodiment, a second air groove 1060 is provided on the second limiting portion 106.

A telescopic device 203 is provided on the module bracket 20 of the supplementary percussion module 3001. One end of the telescopic device 203 is fixed to the module bracket 20, and the other end is fixed to the mounting bracket 40. According to the result detected by the rust detection device 500, the corresponding telescopic device 203 is controlled to extend or retract. When the rust detection device 500 detects that the rust at a certain position is unqualified, the corresponding telescopic device 203 extends, and the rust removal module 1 corresponding to the telescopic device 203 can contact the material 800 to remove rust from the material 800.

[0117] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described.
