Description

Technical Field

[0001] The present invention relates to the technical field of surface shot peening treatment, and particularly relates to a mobile vehicle-mounted shot peening machine. Background Art

[0002] In the field of vehicle-mounted shot peening machines, China is currently in a stage of lack of wide application of technology. In the prior art, a Chinese invention patent with the application number 201310476180.6 discloses a cab shot peening machine. As a large shot peening treatment device with a walking system, although it can cope with the high-efficiency shot peening treatment operation of the large-area surface of large buildings, the front shot peening treatment unit in this cab shot peening machine adopts a horizontally movable design to achieve the purpose of horizontally adjusting the shot peening treatment position. However, we found in actual operation that this horizontally movable design has almost no practical operation significance, and due to this design, the whole machine cannot process the surface near the wall or corner position (there is always a large distance between the treatment surface and the wall, otherwise the driving and power units of the whole machine are too close to the wall and are prone to safety hazards such as rollover), and there are obvious limitations in use.

[0003] In view of this, it is an urgent problem for us to solve the defect that the current large vehicle-mounted shot peening machine cannot process the position near the wall or corner. Summary of the Invention

[0004] The purpose of the present invention is to provide a mobile vehicle-mounted shot peening machine to solve the problem that the current large vehicle-mounted shot peening machine cannot process the position near the wall or corner.

[0005] The purpose of the present invention is achieved through the following technical solutions: A mobile vehicle-mounted shot peening machine includes a shot peening system, a driving system, and a dust removal system. The shot peening system includes a mounting frame, a main shot peening unit, and at least one set of side shot peening units. The mounting frame includes a connecting plate, a main connecting member for connecting the main shot peening unit and capable of tilting the front end of the main shot peening unit upward or downward, and a side connecting member for connecting the side shot peening unit and capable of tilting the front end of the side shot peening unit upward or downward. The connecting plate is connected to one side of the driving system. The main connecting member is installed between the connecting plate and the main shot peening unit. The side connecting member is installed between the connecting plate and the side shot peening unit.

[0006] Further, the main connecting member includes a main transverse shaft, two main connecting arms fixedly connected to the main transverse shaft, and at least one set of first power components connected to the main transverse shaft. The two main connecting arms are respectively fixedly connected to both sides of the main shot blasting unit. The fixed end of the first power component is installed on the connecting plate, and the output end of the first power component is fixedly connected to the main transverse shaft and can swing the main transverse shaft up and down. The side connecting member includes a side transverse shaft, at least one side connecting arm, and at least one set of second power components. At least one side connecting arm is connected between the side shot blasting unit and the side transverse shaft. The fixed end of the second power component is installed on the connecting plate, and the output end of the second power component is fixedly connected to the side transverse shaft and can swing the side transverse shaft up and down.

[0007] Further, both the first power component and the second power component include a telescopic oil cylinder and a bent arm connected to the piston rod of the telescopic oil cylinder. One end of the bent arm is fixedly connected to the piston rod of the telescopic oil cylinder, and the other end is hinged to the connecting plate. The middle part of the bent arm of the first power component is fixed on the main transverse shaft, and the middle part of the bent arm of the second power component is fixed on the side transverse shaft.

[0008] Further, the main shot blasting unit includes a shot blasting chamber, a rebound bin, and a separation bin. The separation bin is connected between the shot blasting chamber and the upper port of the rebound bin. A multi-stage deceleration bin and a wind force adjustment bin are arranged in the separation bin. The multi-stage deceleration bin is located between the rebound bin and the wind force adjustment bin, and the multi-stage deceleration bin includes a first deceleration component and a second deceleration component for decelerating the shot flow emitted from the rebound bin. The first deceleration component is connected between the outlet of the rebound bin and the second deceleration component.

[0009] Further, the first deceleration component includes a base plate and at least one deceleration plate. The base plate is connected to the outer wall at the outlet of the rebound bin and is used for guiding the shot material. At least one deceleration plate is arranged between the base plate and the second deceleration component. The side of the first deceleration plate adjacent to the base plate and close to the base plate is located outside the guiding direction of the base plate, and the side of the first deceleration plate far from the base plate is located inside the guiding direction of the base plate. The connection mode between adjacent deceleration plates is the same as the connection mode between the first deceleration plate and the base plate.

[0010] Further, air adjustment openings are formed between the ends of the first deceleration plate and the base plate close to each other and between the ends of adjacent deceleration plates close to each other.

[0011] Further, the second deceleration component includes a deceleration arc plate. One end of the deceleration arc plate is connected to the last deceleration plate, and a discharge port is formed between the other end and the bottom wall of the inner cavity of the separation bin. The center of the arc of the deceleration arc plate is located on the side close to the rebound bin.

[0012] Further, a cleaning mechanism is installed at the lower part of the side of the main shot blasting unit away from the connecting plate. The cleaning mechanism includes a dust-proof cover and support arms fixed on both sides of the dust-proof cover. One ends of the support arms on both sides are fixedly connected to the main shot blasting unit, and a rotating shaft is rotatably installed between the other ends. A shaft sleeve is sleeved on the rotating shaft, and a number of cleaning brush hairs are formed on the shaft sleeve. A motor capable of driving the rotating shaft to rotate is installed on one of the support arms.

[0013] Further, the dust removal system is connected to the side of the driving system away from the shot blasting system, and a shot material recovery mechanism is arranged on the side of the dust removal system away from the driving system.

[0014] Further, the shot material recovery mechanism includes a frame and a belt conveyor assembly installed on the frame. The feeding end of the belt conveyor assembly is inclined downward, and a magnetic drum for supporting belt transmission is sleeved on a roller shaft on one side of the feeding end of the belt conveyor assembly. A number of anti-slip convex edges are processed on the conveying surface of the belt in the belt conveyor assembly. One side of the frame is connected to the dust removal system, and a receiving hopper is arranged on the other side. A baffle plate connected to the discharging end of the belt conveyor assembly is installed on the receiving hopper.

[0015] The beneficial effects of the mobile vehicle-mounted shot blasting machine provided by the embodiment of the present invention are as follows:

[0016] 1. By adding side shot blasting units on at least one side of the main shot blasting unit, the combination between the side shot blasting units and the main shot blasting unit is at least greater than the width of the whole machine, that is, shot blasting treatment can be carried out on the surface near the wall (vertical surface) or the corner, and at the same time, the width of the surface that can be processed at one time is further increased, which further improves the efficiency of the whole surface treatment operation;

[0017] 2. Since the shot material ejected from the rebound bin in the main shot blasting unit has great kinetic energy, the shot material with high speed impact is easy to cause impact damage to the inner cavity part of the separation bin near the rebound bin. By arranging a multi-stage deceleration bin in the main shot blasting unit, the multi-stage deceleration bin includes a first deceleration component with a primary strong deceleration effect and a second deceleration component with a secondary buffering deceleration effect. The arrangement mode of the multi-stage deceleration plates in the first deceleration component can greatly release or reduce the kinetic energy of the reflected shot material, so that the shot material entering the multi-stage deceleration bin, especially the deceleration arc plate part of the second deceleration component, is rapidly decelerated, and will not cause great impact damage to the second deceleration component part. Only by replacing the deceleration plate can the long service life of the multi-stage deceleration bin be ensured;

[0018] 3. An air adjustment port is formed between the multi-stage adjacent deceleration plates in the first deceleration component, that is, the first deceleration component is in a non-sealed state and can communicate with the air volume adjustment bin, so that the shot material in the rebound bin can enter the multi-stage deceleration bin for recovery more smoothly under the combined action of negative pressure suction and rebound force, avoiding the waste phenomenon caused by some shot materials not being smoothly ejected from the ejection port of the rebound bin and the shot materials not being recovered in time;

[0019] 4. By adding a cleaning mechanism in front of the main shot blasting unit, the surface to be treated can be pre-cleaned to reduce the difficulty of separating subsequent steel grit or steel shot from surface impurities;

[0020] 5. By setting up a shot material recovery mechanism behind the dust removal system, a small amount of shot material leaking from the shot blasting unit can be collected in a timely manner. This can not only prevent the shot material from scattering onto the surface being shot blasted, affecting the cleanliness of the overall working environment, but also further reduce the consumption of shot material, achieving the purpose of high resource utilization rate and high recovery rate.

[0036] Embodiment

[0037] Please refer to Figure 1, the mobile vehicle-mounted shot blasting machine provided in this embodiment includes a shot blasting system 1, a power system 2, a driving system 3, and a dust removal system 5 that are connected in sequence. The shot blasting system 1 is located on the forward side of the driving system 3. Of course, the shot blasting system 1 can also be located on the non-forward side of the driving system, that is, both the left and right sides and the rear side are acceptable. According to the usual processing direction in China, it is preferably that the shot blasting system 1 is located on the forward side of the driving system 3 in this embodiment. The dust removal system 5 is located on the side of the driving system 3 away from the shot blasting system 1. The power system 2 is integrated on the driving system 3 and provides sufficient driving forward force for the whole machine. The main working principle of this shot blasting machine is that the whole machine is driven forward by the power system 2, the shot blasting system 1 performs shot blasting on the surface to be processed, and the generated dust impurities are connected to a sedimentation tank 7 on one side of the driving system 3 through multiple dust removal pipes connected to the shot blasting system 1. After the sedimentation tank 7 preliminarily settles the dust, it is then discharged into the dust removal system 5 for sufficient dust reduction. The fan 8 installed on the dust removal system 5 provides sufficient negative pressure suction for the entire circulating air duct, that is, the impurities generated at the shot blasting system 1 are sucked into the dust removal system 5 through the negative pressure suction generated by the fan 8, passing through the dust removal pipes and the sedimentation tank 7. Since the negative pressure suction generated by the fan 8 is quite large, high-frequency noise will be generated during operation, which will affect the normal operation of the driver on the driving system 3 and there will be certain safety hazards. Therefore, the driver's cab of the driving system 3 adopts the form of an engineering vehicle cab 4. This way of isolated operation not only has a certain protective function, but also can greatly reduce the impact of noise on the operator. At the same time, it has its own air conditioning temperature control system, which can provide a safe and comfortable operation environment for the operator.

[0038] Due to the problem of technical bottlenecks in shot blasting machines, the larger the size of the shot blasting part (the larger the processing surface of the rebound impact port), the easier it is to cause shot material leakage. Therefore, the width of the shot blasting part is always smaller than the width of the whole machine in order to achieve a better shot material recovery rate, which will result in the whole machine being unable to perform shot blasting on the surface close to the wall or vertical surface. Otherwise, if the whole machine is too close to the vertical surface, it is easy to cause scratching or even tipping over. In order to be able to perform shot blasting on the surface close to the wall or vertical surface on the premise that the whole machine is safe and does not tip over or the driving system 3 does not wear the vertical surface, please refer to Figure 2, the shot blasting system 1 includes a mounting frame, a main shot blasting unit 11, and at least one set of side shot blasting units 12. When there is one set of side shot blasting units 12, the side shot blasting unit 12 can be located on the left or right side of the main shot blasting unit 11. One set of side shot blasting units 12 and one set of main shot blasting units 11 are connected to the driving system 3 through the mounting frame, which can also achieve the purpose of greatly increasing the processing surface and being able to process the surfaces near the wall or corner. When there are two or more sets of side shot blasting units 12, all the side shot blasting units 12 are arranged on the left and right sides of the main shot blasting unit 11 in a sequential superposition manner, with one on the left and one on the right. Considering the actual application in the field of shot blasting machines, the number of sets of side shot blasting units 12 is preferably an even number (2, 4, 6 sets), and they are evenly distributed on the left and right sides of the main shot blasting unit 11. This form of combining the main shot blasting unit 11 and the side shot blasting units 12, compared with the existing driving type front side shot blasting mechanism with only the main shot blasting unit, not only removes the meaningless side shift unit structure, ensures a relatively reliable rigid connection between the entire front main and side shot blasting units and the whole machine, prevents a large amount of steel shot from leaking during work due to unstable connection, but also the combination of the side shot blasting units 12 and the main shot blasting unit 11 can increase the width of the overall shot blasting unit at the front end. It can make the side shot blasting units 12 approach the vertical surface or wall on the premise that the power system 2 is not too close to the vertical surface or wall, achieving the purpose of being able to process the surface near the wall, and also reducing the possibility of mutual rubbing or tipping between the whole machine and the wall.

[0039] In this embodiment, considering the comprehensiveness of the function of processing the surface near the wall surface, that is, it can not only process the left near-wall surface in the same direction, but also process the right near-wall surface in the same direction. The number of groups of the side shot blasting units 12 is preferably two, and they are respectively installed on both sides of the main shot blasting unit 11, that is, the left and right sides, so as to achieve the purpose of being able to process the horizontal surfaces near the left wall and the right wall in the same direction. Due to the particularity of the shot blasting machine, during operation, its bottom impact surface needs to be almost in micro-gap fit with the surface to be processed (only leaving a gap of about 1-3 cm to install the rest of the sealing mechanism). After the shot blasting operation is completed, the whole machine needs to be packed in a box for transfer. Since its "chassis" is too low, a lifting mechanism must be designed to make the front end of the shot blasting part tilt up so as to walk on the slope for packing, especially for the shot blasting mechanism with a large body size. In order to be able to lift the main shot blasting unit 11 and the side shot blasting units 12 to a certain extent, we have optimized the design and improvement of the mounting frame. Specifically, the mounting frame includes a connecting plate 13, a main connecting piece for connecting the main shot blasting unit 11 and capable of tilting the front end of the main shot blasting unit 11 up or down, and a side connecting piece for connecting the side shot blasting units 12 and capable of tilting the front end of the side shot blasting units 12 up or down. The connecting plate 13 is detachably and fixedly connected to the front side of the driving system 3. Among them, the main connecting piece includes a main horizontal shaft 15, two main connecting arms 14 fixedly connected to the main horizontal shaft 15, and at least one set of first power components connected to the main horizontal shaft 15. The two main connecting arms 14 are used to fixedly connect the two sides of the main shot blasting unit 11 (rebound bin). The fixed end of the first power component is installed on the connecting plate 13, and the output end of the first power component is fixedly connected to the main horizontal shaft 15 and can make the main horizontal shaft 15 swing up and down. Similarly, the side connecting piece includes a side horizontal shaft 16, two side connecting arms 19 fixedly connected to the side horizontal shaft 16, and at least one set of second power components. The two side connecting arms 19 are used to fixedly connect the two sides of the side shot blasting units 11 (rebound bin or shot blasting chamber). The fixed end of the second power component is installed on the connecting plate 13, and the output end of the second power component is fixedly connected to the side horizontal shaft 16 and can make the side horizontal shaft 16 swing up and down.

[0040] In this embodiment, the structural design of the main connecting piece and the side connecting piece can not only realize the reliable connection between the connecting plate 13 and the main shot blasting unit 11 and the side shot blasting units 12, but also realize the function of separately controlling the main shot blasting unit 11 and the side shot blasting units 12. In another embodiment, the main horizontal shaft 15 and the two side horizontal shafts 16 on both sides are integrally formed coaxially, and there is only one side connecting arm 19 in each side shot blasting unit 12. The two sides of the main connecting arm 14 are respectively fixedly connected to the main shot blasting unit 11 and the side shot blasting units 12. The single side connecting arm 19 is fixed on the side of the side shot blasting unit 12 away from the main shot blasting unit 11, and there is no need to set up a second power component. The mounting frame in this embodiment can achieve the purpose of controlling the front ends of the main shot blasting unit 11 and the side shot blasting units 12 to tilt up or down simultaneously under the action of the first power component.

[0041] The first power assembly and the second power assembly may be electric assemblies or pneumatic assemblies. In order to achieve the purpose of stable and reliable tilting up or down at the front end of the main shot blasting unit 11 or the side shot blasting unit 12, in this embodiment, the first power assembly and the second power assembly are both implemented by hydraulic assemblies with the same structure. The first power assembly and the second power assembly both include a telescopic oil cylinder 18 and a bent arm 17 connected to the piston rod of the telescopic oil cylinder 18. The bent arm 17 is an L-shaped cast iron plate or steel plate. One end of the bent arm 17 is fixedly connected to the piston rod of the telescopic oil cylinder 18, and the other end is hinged to the connecting plate 13 through a hinge seat. Among them, the middle part of the bent arm 17 of the first power assembly is fixedly sleeved on the main cross shaft 15, and the middle part of the bent arm 17 of the second power assembly is fixedly sleeved on the side cross shaft 16. By controlling the telescopic oil cylinder 18 to extend or retract, the main cross shaft 15 or the corresponding side cross shaft 16 rotates clockwise or counterclockwise, so as to realize the tilting up or down of the front end of the main shot blasting unit 11 or the side shot blasting unit 12. Considering that the weight of the main shot blasting unit 11 is greater than that of the side shot blasting unit 12, there are two groups of the first power assemblies in the main connecting piece. The two groups of the first power assemblies are respectively located on both sides of the middle part of the main cross shaft 15 and are symmetrically distributed about the middle part of the main cross shaft 15. The position of each group of the first power assemblies is preferably on the main cross shaft 15 close to the inner side of the main connecting arm 14. The two groups of the first power assemblies can provide sufficient stable lifting force for the main shot blasting unit 11, and only one group of the second power assembly is configured in the side connecting piece.

[0042] Since the processing surface of the main shot blasting unit 11 is several times larger than that of the current medium and small shot blasting equipment, in the field of our shot blasting machines, increasing the processing surface does not simply mean enlarging the design size. The reason is that the shot blasting operation impacts the surface to be processed with high-speed sprayed steel shots or steel sands. After enlarging the size of the shot blasting mechanism, the power motor cannot meet the requirements of ultra-high speed and ultra-large torque, or the steel shots can still meet the requirement of high-speed spraying in a larger volume. Therefore, it is necessary to improve the main shot blasting unit 11. Please refer to Figure 3 , both the main shot blasting unit 11 and the side shot blasting unit 12 include a shot blasting chamber 111, a rebound bin 112 and a separation bin 113. The separation bin 113 is connected and communicated between the upper ports of the shot blasting chamber 111 and the rebound bin 112. An impact and rebound port is formed between the lower ports of the shot blasting chamber 111 and the rebound bin 112. The entire trajectory of the steel shots is thrown out of the shot blasting chamber 111 at high speed, passes through the impact and rebound port and impacts the surface to be processed at high speed, and then rebounds into the rebound bin 112, slowly decelerates and finally enters the separation bin 113. The knocked-off impurities and the steel shots are separated in the separation bin 113. The impurities are sucked away by the fan 8 through a pipeline, and the steel shots settle to the bottom of the separation bin 113, waiting to enter the shot blasting chamber 111 for the next cycle.

[0043] Among them, the dust removal pipelines of the side shot blasting unit 12 and those of the main shot blasting unit 11 can be arranged separately or bundled together. In the shot blasting chamber 111 of the side shot blasting unit 12, a set of shot blasting wheel assemblies and a motor for driving the shot blasting wheels therein to rotate at high speed can be provided. In the shot blasting chamber 111 of the main shot blasting unit 11, at least two sets of shot blasting wheel assemblies must be installed and the corresponding number of motors must be equipped. This method of superposition by quantity can solve the problem that currently, due to the technical bottleneck of motors, a single set of shot blasting wheel assemblies cannot be used for wide surface treatment. The number of sets of shot blasting wheel assemblies is determined according to the width or processing volume of the processing surface of the main shot blasting unit 11. In this embodiment, two sets of shot blasting wheel assemblies are installed in the shot blasting chamber 111 of the main shot blasting unit 11, and the two sets of shot blasting wheel assemblies are arranged side by side along the axial direction of the main horizontal axis 15, so as to achieve the optimal superposition of the processing surface width.

[0044] To ensure that the surface to be processed has a high cleanliness in addition to removing rust, a cleaning mechanism 9 is installed at the lower part of the side of the main shot blasting unit 11 away from the connecting plate 13. The cleaning mechanism 9 includes a dust-proof cover 92 and support arms 91 fixed on both sides of the dust-proof cover 92. One ends of the support arms 91 on both sides are fixedly connected to the front side wall of the lower part of the rebound bin 112 in the main shot blasting unit 11, and the other ends are rotatably installed with a rotating shaft 93 through bearings. The rotating shaft 93 is horizontally placed below the middle of the dust-proof cover 92, and a sleeve is sleeved on the rotating shaft 93. The length of the sleeve is preferably the distance between the support arms 91 on both sides. A number of cleaning brush bristles 94 are formed on the sleeve. The cleaning brush bristles 94 are strip-shaped bodies made of plastic, preferably made of polyurethane. All the cleaning brush bristles 94 form a cylindrical shape distributed along its axial direction on the surface of the sleeve. The upper part of this combined cylindrical shape is covered in the inner hole of the dust-proof cover 92, which can play a good role in dust suppression and prevent interference with the operator's line of sight. A motor (not shown) for driving the rotating shaft 93 to rotate is installed on one of the support arms 91. In other embodiments, the motor can also be replaced with a hydraulic motor, a gear assembly or a belt assembly and other power output mechanisms, which are not limited here. By controlling the motor to start, the rotating shaft 93 can be rotated clockwise, and the cleaning brush bristles 94 will sweep the slag blocks on the surface to be processed outwards to ensure that the surface to be processed below the subsequent impact rebound port has a high cleanliness. It should be noted that the length of the entire protective cover 92 can be equal to the sum of the widths of the main shot blasting unit 11 and the two side shot blasting units 12 superimposed, so that the cleaning surface can cover the width of the entire shot blasting treatment surface. In another embodiment, the cleaning mechanism 9 can also be a blowing mechanism. The layout form of the blowing mechanism is roughly the same as that of the cleaning mechanism, except that the dust-proof cover 92 is designed as a housing form with an air inlet on one side and an air outlet on the other side, and the cleaning brush bristles 94 on the rotating shaft 93 are replaced with fan blades.

[0045] Since the volume of the main shot blasting unit 11 is several times larger than that of the side shot blasting unit 12 in terms of processing surface and processing volume, it requires a greater negative pressure suction force for the shot to smoothly enter the separation chamber 113 from the rebound chamber 112 of the main shot blasting unit 11, which will cause the shot ejected from the rebound chamber 112 to carry huge kinetic energy. The high-speed impacting shot is likely to cause serious impact damage to the inner cavity of the separation chamber 113 near the rebound chamber 112. In order to overcome this problem, the present application mainly designs and improves the separation chamber 113 of the main shot blasting unit 11. Of course, the separation chamber 113 of the side shot blasting unit 12 can adopt the same improvement. In this embodiment, the separation chamber 113 of the main shot blasting unit 1 is used for explanation. Please refer to Figure 4 The separation bin 113 is provided with a multi-stage deceleration bin 1131, a wind force adjustment bin 1132 and a magnetic separation roller mechanism 1134. The multi-stage deceleration bin 1131 is used for multi-stage deceleration of the shot materials ejected from the rebound bin 112. The wind force adjustment bin 1132 is used for adjusting the air intake volume in the entire separation bin 113. The magnetic separation roller mechanism 1134 is used for magnetically separating steel shots and impurities. The multi-stage deceleration bin 1131 is connected between the rebound bin outlet 1121 and the magnetic separation roller mechanism 1134. The wind force adjustment bin 1132 is located on the side of the multi-stage deceleration bin 1131 away from the rebound bin 112.

[0046] In this embodiment, the multi-stage deceleration chamber 1131 mainly includes a first deceleration assembly and a second deceleration assembly, wherein the first deceleration assembly is connected between the rebound chamber outlet 1121 and the second deceleration assembly, and is used to perform a strong first-stage deceleration on the shot materials ejected from the rebound chamber 112, and the second deceleration assembly is connected between the first deceleration assembly and the magnetic separation roller mechanism 1134, and is used to perform a second-stage buffer deceleration on the shot materials that have released a large amount of kinetic energy after the first-stage deceleration. The first deceleration assembly and the second deceleration assembly are both composed of a combination of steel plates or cast iron plates with high impact resistance, which means that the first deceleration assembly and the second deceleration assembly are both composed of a plurality of steel plates or cast iron plates in a certain arrangement, which can be an end-to-end connection arrangement, a directional superposition arrangement, or a multi-angle bending arrangement, as long as the trajectory of the shot materials passing through the plate is not a continuous uniform straight surface or curved surface, which means that the trajectory of the shot materials has a low degree of smoothness, and can play a certain role in reducing the speed or decelerating the high-speed shot materials.

[0047] In order to fully release the energy of the projectiles, please refer to Figure 5, the first deceleration component includes a substrate 11311 and at least one deceleration plate 11312. The substrate 11311 is connected to the outer wall at the outlet 1121 of the rebound bin and is used to divert the pellets. The outer wall at the outlet 1121 of the rebound bin means that the outlet on the side where the rebound bin 112 is connected to the separation bin 113 is the outlet, and the side wall of the outlet away from the magnetic separation drum mechanism 1134 is its outer wall. The function of the substrate 11311 is to guide the flow of the pellets (including impurities) that just rebound to the outlet, that is, the diversion function. The substrate 11311 can be smoothly transitioned and parallelly connected to the outer wall at the outlet 1121 of the rebound bin. In another embodiment, an angle can also be formed between the substrate 11311 and the outer wall at the outlet 1121 of the rebound bin, that is, the end (upper end) of the substrate 11311 away from the outer wall at the outlet 1121 of the rebound bin is inclined towards the magnetic separation drum mechanism 1134 side. The pellets that just rebound to the outlet 1121 directly impact the substrate 11311 from the outer wall at the outlet 1121 of the rebound bin to achieve the purpose of preliminary speed reduction. In this embodiment, the substrate 11311 and the outer wall at the outlet 1121 of the rebound bin are smoothly transitioned and parallelly connected, mainly playing the role of diverting or guiding the flow of the pellets, while the subsequent deceleration plate 11312 plays the main deceleration role.

[0048] Specifically, the speed reducer plate 11312 can be a selection of a plate with a relatively wide size or a combination of multiple plates with relatively narrow sizes. In order to achieve sufficient speed reduction and energy release, in this embodiment, the number of speed reducer plates 11312 is preferably two. The two speed reducer plates 11312 are arranged in sequence between the substrate 11311 and the second speed reduction component. The side of the first speed reducer plate 11312 (the first speed reducer plate 11312) connected to the substrate 11311 and close to the substrate 11311 is located outside the diversion direction of the substrate 11311. This outside also refers to the side away from the magnetic separation drum mechanism 1134. And the side of the first speed reducer plate 11312 away from the substrate 11311 is located inside the diversion direction of the substrate 11311, that is, the side close to the magnetic separation drum mechanism 1134. The shot peening media that is initially diverted from the substrate 11311 directly impacts on the first speed reducer plate 11312 to achieve the purpose of preliminary speed reduction. The connection method between the two speed reducer plates 11312 is the same as the connection method between the first speed reducer plate 11312 and the substrate 11311. That is, the side of the last speed reducer plate 11312 (the second speed reducer plate 11312) close to the first speed reducer plate 11312 is located outside the diversion direction of the first speed reducer plate 11312, and the side of the last speed reducer plate 11312 away from the first speed reducer plate 11312 is located inside the diversion direction of the first speed reducer plate 11312. The shot peening media that is initially decelerated from the first speed reducer plate 11312 directly impacts on the last speed reducer plate 11312 to achieve the purpose of further speed reduction. Of course, this arrangement can be continued to stack the third or fourth speed reducer plate 11312 to achieve the purpose of sufficient energy release and speed reduction, which will not be elaborated here. In another embodiment, the substrate 11311 can be removed or the substrate 11311 can be used as the first speed reducer plate 11312 for arrangement. The outer wall at the outlet 1121 of the rebound bin is used for the initial diversion of the shot peening media, and after the diversion, it directly impacts on the substrate 11311 for preliminary speed reduction.

[0049] The included angle between the substrate 11311 and the first deceleration plate 11312 may not be equal to the angle value of the included angle between the first deceleration plate 11312 and the last deceleration plate 11312. However, it is preferably satisfied that the included angle value of the latter is greater than or equal to that of the former, so as to ensure that the shot material can sequentially impact all the deceleration plates 11312 and can play a more and more sufficient role in decelerating and releasing energy for the shot material. In this embodiment, the two deceleration plates 11312 are parallel to each other, that is, the included angle between the first deceleration plate 11312 and the substrate 11311 is equal to the angle value of the included angle between the first deceleration plate 11312 and the last deceleration plate 11312. And each deceleration plate 11312 is detachably installed between the inner walls of the separation chambers 113 on both sides of the multi-stage deceleration bin 1131. The detachable method can be by bolt connection, by snap-fastening with fasteners, or by stably inserting the deceleration plate 11312 into the corresponding slots on the separation chamber 113. It only needs to ensure that the deceleration plate 11312 can not only be stably installed but also achieve the purpose of quick disassembly. Since the deceleration plate 11312 is the most critical and the most front-end component for shot material deceleration, it acts as a consumable part and needs to be frequently replaced or maintained. Its quick disassembly function can reduce the operation difficulty of subsequent replacement or maintenance.

[0050] The entire first deceleration component and the second deceleration component can be in a sealed state, which means that both sides of the first deceleration component and the second deceleration component are fixed between the inner walls of the separation chambers 113 on both sides of the multi-stage deceleration chamber 1131, isolating the multi-stage deceleration chamber 1131 from the wind force adjustment chamber 1132 to ensure that the pellets will not be easily sucked into the wind force adjustment chamber 1132, causing certain waste. However, in this embodiment, in order to achieve the full recovery of the pellets and impurities and better separate the pellets from the impurities, air adjustment openings 11313 are formed between the ends of the first deceleration plate 11312 and the substrate 11311 on the side close to each other, and between the ends of the two deceleration plates 11312 on the side close to each other. The air adjustment opening 11313 refers to the gap between the two plates on the close side. In another embodiment, the air adjustment opening 11313 can also be obtained by self-processing of the substrate 11311 or the deceleration plate 11312, and the adjacent plates are sealed and connected, but this method increases the processing difficulty. In order to achieve better sealing of the first deceleration component in an incompletely sealed state, the length of the substrate 11311, the deceleration plate 11312, and the air adjustment opening 11313 are equal, and the width of the air adjustment opening 11313 is smaller than the diameter of the pellets, allowing impurities (relatively smaller than the pellets) to pass through, but not allowing the pellets to pass through. This design is to increase the effective area of communication between the wind force adjustment chamber 1132 and the rebound chamber 112, so that the negative pressure wind force (connected to the dust removal system) in the wind force adjustment chamber 1132 increases the direct suction effect on the pellets and impurities in the rebound chamber 112, making the pellets in the rebound chamber 112 more smoothly enter the multi-stage deceleration chamber 1131 for recovery under the combined action of the negative pressure suction force and the rebound force, thus avoiding the waste phenomenon caused by some pellets not being smoothly ejected from the ejection port 1121 of the rebound chamber and not being recovered in time. In addition, the impurities are adsorbed from the rebound chamber 112 into the multi-stage deceleration chamber 1131 and can be directly sucked into the dust removal pipe through the air adjustment opening 11313, which can reduce the burden of separating impurities in the subsequent separation chamber 113, so as to achieve a more efficient separation of the pellets and impurities.

[0051] In order to adapt to different working conditions, the degree of surface rust or corrosion to be treated varies. Some are severely rusted or corroded, while others are in a mild state. The total amount of impurities carried or rebounded after shot peening treatment is different. When there are more impurities, a larger negative pressure suction is required to obtain a higher separation efficiency, and vice versa, a smaller wind force is needed. Therefore, a wind force adjustment component 1133 for adjusting the air volume at the air inlet is provided in the wind force adjustment chamber 1132. Specifically, one side of the wind force adjustment component 1133 is communicated with the air adjustment port 11313. An air inlet communicated with the wind force adjustment component 1133 is processed on the top of the separation chamber 113. The wind force adjustment component 1133 is located on the aisle between the air inlet and the air adjustment port 11313. It mainly changes the size of the air volume passing through by changing the effective blocking area on its surface. Any structure that can achieve the purpose of adjusting the wind by changing its own effective blocking area is acceptable. For example, a combination of telescopic connections between multiple plates or a combination of two plates being pushed away from or close to each other by a driving member. Or a combination of a plate that can change its own inclination angle and a hinge member, and the channel is opened or closed by turning. In this embodiment, a combination of telescopic connections between multiple plates is preferably used, which is not only reliably connected and can resist the suction of strong winds, but also convenient to adjust. Specifically, the wind force adjustment component 1133 includes at least two windshields. The adjacent windshields are connected in a telescopic manner. The telescopic connection method is a combination of a chute and a sliding protrusion with a locking bolt, or a combination of a sliding hole and a sliding pin with a self-locking thread, etc. Here, the second method is used. And the number of windshields is three. The three windshields are parallel to each other. The middle windshield is used as a reference and multiple sliding pins are formed on one side surface thereof. Bar-shaped sliding holes are correspondingly processed on the other two windshields. The side windshields are telescopically connected along the length direction of the bar-shaped holes by sleeving their sliding holes on the sliding pins of the middle windshield. Threads are processed on the sliding pins, and the side windshields and the middle windshield are stably fixedly connected by mating nuts. The entire wind force adjustment component 1133 composed of three windshields is inclinedly arranged in the wind force adjustment chamber 1132, and the two side walls of the non-telescopic ends of the side windshields are non-contactingly close to the side walls of the wind force adjustment chamber 1132. The two side walls of the non-telescopic end of the middle windshield are fixedly welded to the side walls of the wind force adjustment chamber 1132 or detachably connected by bolts. By adjusting the relative distance between the side windshields and the middle windshield, the telescopic function of the wind force adjustment component 1133 is realized, so as to achieve the purpose of controlling the air volume entering between the air inlet and the air adjustment port 11313 per unit time. By designing the top wall of the separation chamber 113 at the air inlet in the form of a maintenance plate or a maintenance port, the purpose of convenient operation of the wind force adjustment component 1133 can be achieved.

[0052] After the pellets (including some impurities) have been strongly decelerated by the first deceleration component, a large amount of kinetic energy has been released. After that, they can be smoothly guided to the magnetic separation drum mechanism 1134 only through buffer deceleration and guidance. The pellets with greatly reduced speed will not cause excessive impact damage to the second deceleration component and the magnetic separation drum mechanism 1134, ensuring a long service life of the second deceleration component and the magnetic separation drum mechanism 1134. The second deceleration component includes a deceleration arc plate 11314 and a primary screening and separation plate 11316. One end of the deceleration arc plate 11314 is connected to the last deceleration plate 11312, and the connection method can adopt a non-contact connection method forming an air adjustment port 11313. A discharge port 11315 communicating with the magnetic separation drum mechanism 1134 is formed between the other end of the deceleration arc plate 11314 and the inner cavity bottom wall of the separation chamber 113. In this embodiment, the longitudinal section shape of the deceleration arc plate 11314 is approximately C-shaped, and the arc center of the deceleration arc plate 11314 is located on the side of the deceleration arc plate 11314 close to the rebound chamber 112, that is, it means that the deceleration arc plate 11314 bends and protrudes outward toward the air volume adjustment chamber 1132, which can make the decelerated pellets smoothly buffer, decelerate and be guided inside the deceleration arc plate 11314. And one end of the deceleration arc plate 11314 close to the last deceleration plate 11312 is the maximum bending arc, and the tangential direction of the end of the deceleration arc plate 11314 close to the last deceleration plate 11312 coincides with the diversion direction of the substrate 11311, which can ensure that all pellets can be ejected onto the inner side wall of the deceleration arc plate 11314 after multi-stage deceleration, and the pellets ejected onto the inner side wall of the deceleration arc plate 11314 can be initially decelerated through the maximum bending arc, so that the speed of the pellets entering the subsequent part with a small bending angle can be further reduced. The steel pellets enter the second deceleration component under the strong deceleration of the first deceleration component, which can ensure that the second deceleration component will not be strongly impacted and cause a serious decline in service life, and the buffer deceleration function of the second deceleration component itself can also ensure that there will be no serious impact damage to itself and the part close to the magnetic separation drum mechanism 1134.

[0053] The primary screening and separation plate 11316 is installed inside the separation chamber 113 on the side where the center of the arc of the deceleration arc plate 11314 is located, i.e., the concave side. The two sides of the primary screening and separation plate 11316 are detachably connected to the separation chamber 113 by means of detachable connection between the deceleration plates 11312 and the separation chamber 113. The primary screening and separation plate 11316 is located between the connecting lines of the air adjustment opening 11313 and the discharge opening 11315. An upper passage 11317 is formed between the upper end of the primary screening and separation plate 11316 and the deceleration arc plate 11314 for relatively high-speed and relatively large kinetic energy shot materials to pass through. A lower passage 11318 is formed between the lower end of the primary screening and separation plate 11316 and the bottom wall of the inner cavity of the separation chamber 113 for shot materials (including impurities) that have fully released their kinetic energy to pass through. The design of this primary screening and separation plate 11316 can add a barrier between the air adjustment opening 11313 and the discharge opening 11315 to achieve the purpose of separating shot materials and impurities again and decelerating them again. Specifically, the lower end of the primary screening and separation plate 11316 is inclined towards the substrate 11311 side, preferably parallel to the substrate 11311. A number of sieve holes are processed on the primary screening and separation plate 11316, and the size of the sieve holes is slightly larger than the diameter of the steel shot. After the shot materials and impurities ejected from the rebound chamber 112 are strongly decelerated by the first deceleration component, some shot materials with relatively small kinetic energy, especially most of them are impurities (impurities are light in mass and small in kinetic energy), directly fall downward or are projected at a small angle after the first-stage deceleration and can directly land on the primary screening and separation plate 11316. Due to the relatively small rolling friction of the steel shot, it can directly roll through the sieve holes or along the bottom of the primary screening and separation plate 11316 to the bottom wall of the inner cavity of the separation chamber 113 and enter the discharge opening 11315. Impurities do not have a smooth rolling function and most of them stay on the primary screening and separation plate 11316, and a small part falls through the sieve holes to the bottom wall of the inner cavity of the separation chamber 113. Due to the specific position and orientation of the primary screening and separation plate 11316 being conducive to the air suction effect of the air adjustment opening 11313, most of the impurities on it can pass through the air adjustment opening 11313 and enter the air force adjustment chamber 1132 for recovery. The design of the second deceleration component can not only further buffer and decelerate and guide the shot materials and impurities after strong deceleration, but also further screen and separate the shot materials and impurities to improve the separation efficiency of the subsequent magnetic separation drum mechanism 1134.

[0054] Since during the operation of the whole machine, especially at the shot blasting system 1, a small amount of steel shot will leak. These steel shots scattered on the surface to be shot blasted will not only affect the cleanliness of the overall working environment, but also cause waste of steel shot. In order to collect the leaked steel shot in a timely manner, please refer to Figure 6, so as to reduce the consumption of steel shots and achieve the purpose of high resource utilization rate and high recovery rate. A shot material recovery mechanism 6 is arranged at the lower part on the side of the dust removal system 5 far away from the driving system 3. The shot material recovery mechanism 6 adopts the principle of magnetic separation, adsorbs the steel shots onto the transmission surface at the inlet end with magnetic adsorption, continues to keep the steel shots transmitted until they reach the position where the magnetic adsorption effect disappears, and the steel shots automatically fall off, so as to achieve the purpose of adsorbing, collecting and storing the steel shots.

[0055] The shot material recovery mechanism 6 is designed according to the above-mentioned magnetic separation principle. In order to achieve a high recovery utilization rate of steel shots on the premise of relatively low production cost, please refer to Figure 7 and Figure 8 , in this embodiment, the shot material recovery mechanism 6 includes a frame 61 and a belt conveyor assembly 62 installed on the frame 61. The belt conveyor assembly 62 is mainly composed of roller shafts fixed between the head and tail ends of the two side frames on both sides and a belt drivingly installed on the two roller shafts. The number of roller shafts can be increased according to the increase of the conveying length. Here, the conveying length is about one meter (the width does not exceed the width of the driving system 3), and two roller shafts can be used. The feeding end (the side of the feeding roller shaft) of the entire belt conveyor assembly 62 is inclined downward. In order not to make the upper conveying surface of the belt conveyor assembly 62 too inclined and cause unsmooth material conveying, the diameter size of the roller shaft at the feeding end, that is, the feeding roller shaft, is about 3 times the diameter size of the roller shaft at the discharging end. When the entire belt conveyor assembly 62 is inclined at about 10° - 15°, its feeding end is inclined downward and close to the surface to be treated, and a magnetic drum 63 for supporting belt transmission is fixedly sleeved on the feeding roller shaft, that is, it means that the side ring surface of the magnetic drum 63 is used for mutual transmission with the inner surface of the belt. The installation of the magnetic drum 63 makes the lower side of the belt at the feeding end of the belt conveyor assembly 62 just about 0.5 - 2 cm away from the surface to be treated, so as to directly adsorb the steel shots scattered on the surface to be treated onto the belt at the feeding end to achieve the purpose of adsorbing and collecting the steel shots.

[0056] To ensure the stable connection of the entire frame 61 and the belt conveyor assembly 62 to the dust removal system 5, two sets of support plates are fixed to the front side of the frame 61. The lower surfaces of the two sets of support plates are respectively installed on the side frames on both sides of the belt conveyor assembly 62 through fasteners such as bolts or setscrews. Of course, the support plates and the vehicle frame can also be fixed by welding. The front end of the support plate is detachably connected to the rear side of the dust removal system 5 (the box body). The detachable connection method can be bolt connection, snap connection by fasteners, or the method of inserting and locking with a socket and a plug board, which is not limited here. An electric drive or a hydraulic drive, such as a motor or a hydraulic motor, is installed on one of the support plates. The output end of the drive is equipped with a driving pulley, and one end on the same side as the feed roller shaft is equipped with a driven pulley. A transmission belt is installed between the driving pulley and the driven pulley. Starting the drive can make the magnetic drum 63 rotate counterclockwise and make the transmission belt drive counterclockwise. To transfer the adsorbed and collected steel shots to another place for storage, a number of anti-slip convex edges 67 are processed on the belt conveying surface 66 of the belt conveyor assembly 62. The anti-slip convex edges 67 serve as a pushing platform to push the adsorbed shot materials along the transmission direction of the belt. Of course, the anti-slip convex edges 67 can be continuous or discontinuous strip-shaped or edge-shaped. To ensure sufficient pushing of the shot materials, the anti-slip convex edges 67 are preferably continuous strips, and the anti-slip convex edges 67 can be straight strips, strips with multiple bends, or wavy strips. Here, it is preferably a straight strip, and the length of the anti-slip convex edge 67 is equal to the width of the belt and just covers between both sides of the belt conveying surface 66. In addition, all the anti-slip convex edges 67 are parallel to each other and are preferably arranged uniformly on the belt conveying surface 66 in a direction perpendicular to the belt transmission direction. The steel shots adsorbed to the belt conveying surface 66 at the feed roller shaft under the action of the magnetic drum 63 move forward following the transmission of the belt and continue to move forward under the blocking action of the anti-slip convex edges 67 until the magnetic adsorption effect decreases to disappear when slowly moving away from the magnetic drum 63, and the steel shots finally move to the discharge end of the belt conveyor assembly 62.

[0057] On one side of the discharge end of the belt conveying assembly 62, there is a receiving hopper 64. The two front ends of the receiving hopper 64 are respectively fixedly connected or detachably connected to the side frames on both sides of the belt conveying assembly 62. The detachable connection method can be by bolt connection, by fastening with fasteners, or by inserting and locking a socket and a plug board. The rear side of the receiving hopper 64 and the discharge end of the belt conveying assembly 62 form a receiving opening. The steel shot can fall into the inner cavity of the receiving hopper 64 when it drops from the discharge end of the belt conveying assembly 62. The inner cavity of the receiving hopper 64 can be divided into multiple cavities, and moving rollers are arranged at the bottom of the receiving hopper 64 to ensure the mobility of the entire shot recycling mechanism 6. In order to prevent the steel shot from falling outside the receiving hopper 64 from the discharge end of the belt conveying assembly 62, a baffle plate 65 connected to the discharge end of the belt conveying assembly 62 is installed on the receiving hopper 64. The two front ends of the baffle plate 65 are respectively connected to the rear ends of the side frames on both sides of the belt conveying assembly 62 by adjustable bolts. By adjusting the positions of the adjustable bolts, the distance between the baffle plate 65 and the discharge end of the belt conveying assembly 62 can be changed. A blanking gap for the steel shot is formed between the upper end of the baffle plate 65 and the discharge end of the belt conveying assembly 62. The lower end of the baffle plate 65 is located directly above the inner cavity of the receiving hopper 64. The steel shot reaching the discharge end of the belt conveying assembly 62 can all fall into the inner cavity of the receiving hopper 64 under the blocking action of the baffle plate 65, improving the integrity and sufficiency of the steel shot collection.
