Description

Technical Field

[0001] The invention relates to the field of sandblasting for wrench production, and in particular to a high-efficiency sandblasting device for wrench production. Background Art

[0002] During the production and processing of wrenches, their surfaces require sandblasting. The principle of sandblasting is to use the impact of a high-speed sand stream to clean and roughen the substrate surface. Sandblasting can effectively remove oil and coatings attached to the wrench surface during processing, significantly increasing the surface area of the wrench and strengthening the bond between the wrench and the coating / plating. It also has a good rust removal effect on old wrenches. However, due to the irregularities of the wrench, the clamping and fixing effect is poor. Existing sandblasting methods are usually divided into manual sandblasting and conveyor belt sandblasting. Manual sandblasting increases manpower consumption and makes the sandblasting process of the wrench longer, which cannot achieve efficient sandblasting. Transmission belt sandblasting requires manual flipping of the wrench, which also reduces the production efficiency of the wrench and also causes labor consumption. In addition to manual loading and unloading of the sandblasting equipment, a person must continuously flip the wrench to facilitate sandblasting of the contact surface with the conveyor belt, resulting in low efficiency of existing sandblasting methods for wrenches. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-efficiency sandblasting device for wrench production, which has the advantages of saving manpower loss, improving the sandblasting efficiency of the wrench, and reducing subsequent maintenance and repair costs.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A high-efficiency sandblasting device for wrench production, comprising an outer shell structure, the outer shell structure comprising a shell, the interior of the shell is provided with a conveying structure that penetrates to one side of the shell, the conveying structure comprises a loading assembly and a unloading assembly, the loading assembly and the unloading assembly are fixedly sleeved with a transmission assembly 1, one end of the loading assembly is provided with a flip structure located at the top of the unloading assembly, the interior of the shell is respectively provided with a sandblasting structure, a guide plate and a sand cleaning structure, the sand cleaning structure comprises a sand cleaning assembly, a reciprocating assembly, a transmission assembly 2 and a striking assembly, the sandblasting structure comprises a sandblasting assembly 1 and a sandblasting assembly 2, the interior of the shell is provided with a linkage structure that penetrates to one side of the shell, the linkage structure comprises a linkage assembly 1 and a linkage assembly 2, the sandblasting assembly 1 and the linkage assembly 1 are both located on one side of the top of the loading assembly, and the sandblasting assembly 2 and the linkage assembly 2 are both located on one side of the top of the unloading assembly.

[0005] By adopting the above technical solution, before the wrench is sandblasted, the wrench is preferably placed neatly on the surface of the conveyor belt one by manual labor. As the rotating motor runs, the loading assembly will be driven to run, so that the wrench is transferred on the surface of the conveyor belt one. During the transfer of the conveyor belt one, it will be sandblasted by the sandblasting assembly one, and the top of the wrench and the side close to the sandblasting assembly one will be sandblasted. Then the wrench is gradually transferred to the other end of the conveyor belt one, at which time the wrench will be flipped by the setting of the flipping structure. At this time, the flipped wrench will be transferred and fall to the surface of the conveyor belt two. The operation of the unloading assembly will be realized by the setting of the transmission assembly one. At this time, the wrench is continuously transferred by the unloading assembly, and the wrench passes through the sandblasting assembly two and is The sandblasting component 2 sandblasts the top and the side close to the sandblasting component 2 at this time. Through this link, the wrench is turned over, so that the front, back and sides of the wrench are all sandblasted, and the wrench after sandblasting will be continuously transferred through the conveyor belt 2 and manually unloaded by the worker at one end of the conveyor belt 2, or a collection box is placed at the bottom of one end of the conveyor belt 2 to achieve the convenience of collection. The sandblasting device saves manpower loss. During the sandblasting of the wrench, only one person is required to arrange the loading of the wrench in a regular manner, which is different from the inconvenience of existing manual turning and hand-held sandblasting, bringing savings to the company's sandblasting costs. At the same time, the guide plate can guide the sand and gravel missed by the loading component, and its design of tilting to both sides can move the sand and gravel to the sand storage area. The front and rear sides are guided, and the excess sand and gravel of the feeding component can be accumulated in the middle of the sand storage area. The setting of the guide plate ensures the uniformity of the sand and gravel accumulation inside the sand storage area, further saves the sandblasting cost of the sandblasting device, and is convenient for the recycling and reuse of the sand and gravel. In addition, in the sandblasting process of the wrench, the sandblasting component 1 will realize the rocker movement through the linkage component 1, and the sandblasting component 2 will realize the rocker movement through the linkage component 2. The top sandblasting head 1 and the side sandblasting head 1 respectively set by the sandblasting component 1, and the top sandblasting head 2 and the side sandblasting head 2 respectively set by the sandblasting component 2 cooperate with the rocker movement to further ensure the completeness of the sandblasting, and the two adjacent fixed brackets 1 are set at different angles on the surface of the fixed rod 1, and the two adjacent fixed brackets 2 are set at different angles on the surface of the fixed rod 2. The different angle settings of the surface ensure the uniformity of sandblasting, reduce the repeated sandblasting area in the sandblasting of the wrench, and increase the uniformity of sandblasting. At the same time, the setting of the linkage component 1 and the linkage component 2 saves the operating equipment of the sandblasting structure. By sharing a driving device with the transmission structure, the subsequent maintenance cost of the rotating motor is reduced, and the time cost required for maintenance is further saved, which brings convenience to the use of the sandblasting device. At the same time, through the operation of the linkage component 1 and the cooperation of the transmission component 2, the reciprocating operation of the striking component and the sand cleaning component will be realized. The sand cleaning component will realize the striking of the bottom of the conveyor belt 1 and the conveyor belt 2, helping the conveyor belt 1 and the conveyor belt 2 that have passed the wrench to be struck and the gravel stuck or stuck on their surfaces will be knocked off.This prevents gravel on the surfaces of conveyor belts 1 and 2 from being carried outside the housing by the operation of the loading and unloading components, thereby wasting gravel and contaminating the exterior of the housing. This ensures the gravel recovery rate. The striking assembly reciprocates against the curved plate, which vibrates the wrench on one side of the curved plate, improving the wrench flipping completion rate and preventing the wrench from getting stuck in the material passage area, which could cause subsequent wrenches to become blocked, thus ensuring wrench flipping.

[0006] The present invention is further configured as follows: the surface of the shell is rotatably connected to a door body via a hinge, a handle is fixedly installed on the surface of the door body, a visual window is embedded in the surface of the door body, a sand storage area is formed at the bottom inside the shell, one side of the bottom of the shell is connected to a pipe, a material control valve is installed on the pipe, the guide plate is located at the bottom of the conveyor belt and is fixedly connected to the inside of the shell, and the guide plate is designed to be inclined to both sides.

[0007] By adopting the above technical solution, the interior of the shell can be easily operated through the door body, the handle can be conveniently opened and used in conjunction with the door body, and the sandblasting situation inside the shell can be conveniently checked through the setting of the visual window. The sand storage area is convenient for accumulating sand and gravel brought down by sandblasting, and can be connected to the external air supply equipment through a pipeline and discharged in conjunction with the material control valve, so as to facilitate the reuse of the accumulated sand and gravel. The sand and gravel missed by the feeding component can be guided by the guide plate, and its design of tilting to both sides can guide the sand and gravel to the front and back sides of the sand storage area, and the excess sand and gravel of the unloading component can be accumulated in the middle of the sand storage area. The setting of the guide plate ensures the uniformity of the accumulation of sand and gravel inside the sand storage area.

[0009] By adopting the above technical solution, the wrench transmitted from the conveyor belt 1 can be flipped through the setting of the limit plate and the arc plate. The rubber part is elastic and prevents one end of the wrench from contacting the inner side of the shell and causing jamming. At this time, although contact is formed between the wrench and the rubber part, the wrench can be returned to the right track through the elastic characteristics. The arc area 1 matches the curvature of the transmission roller 2, and the arc area 2 will facilitate the transmission of the flipped wrench to the conveyor belt 2. The material passing area cooperates with the wrench for circulation, and the side plate limits the wrench to avoid unpredictable angle changes of the wrench inside the material passing area.

[0011] By adopting the above technical solution, the striking block will contact the bottom of the conveyor belt 1 and the conveyor belt 2 through the contact pad, and through the use of the reciprocating component and the transmission component 2, the conveyor belt 1 and the conveyor belt 2 bottom will be struck back and forth, so that the conveyor belt 1 and the conveyor belt 2 that have passed the wrench can be struck to remove the gravel adhering or stuck on their surfaces. The gravel that has been struck off will be guided by the guide plate and finally accumulated in the sand storage area. At the same time, after the contact pad and the striking block are worn out after long-term use, the rods on both sides of the support plate will be pressed so that the rods can be pushed through the springs. The spring 1 drives the rod back to its initial position. When the striking block needs to be reinstalled, the buckle 2 at the bottom of the striking block is inserted into the supporting plate, and the supporting plate is then pressed downward to form a mutual engagement between the buckle 1 and the buckle 2, thereby completing the replacement of the striking block and increasing the convenience of operation in this link. At the same time, the shape of the supporting plate can prevent sand and gravel from accumulating on the top of the supporting plate.

[0013] By adopting the above technical solution, during the operation of the reciprocating assembly, the contact block three and the sliding rod one can be squeezed by the rotation of the eccentric wheel three. At this time, the sliding rod one moves longitudinally inside the fixed plate, and at the same time, the spring two expands and contracts. The sliding rod one will drive the connecting block and the supporting plate to move longitudinally. During the extension of the spring two, the sliding rod one returns to the initial position, thereby realizing a set of reciprocating striking actions of the reciprocating assembly.

[0014] The present invention is further configured as follows: the striking assembly includes a block, the block and the guide plate are fixedly connected to each other, the interior of the block is provided with a sliding rod 2 that penetrates the top and bottom of the block, the surface of the sliding rod 2 is fixedly sleeved with a spring 3 that is fixedly connected to the inside of the block, the two ends of the sliding rod 2 are respectively fixedly installed with a contact head and a contact block 4, and the bottom of the contact head is provided with an eccentric wheel 4.

[0015] By adopting the above technical solution, when the eccentric wheel four is rotated by the operation of the transmission component two, the eccentric wheel four will squeeze the contact block four, so that the contact block four drives the sliding rod two to move longitudinally inside the block. At the same time, the spring three cooperates with the movement of the sliding rod two to shrink. The sliding rod two will drive the contact head to squeeze and hit the fixed blocks on both sides of the arc plate, and complete a set of reciprocating striking actions on the arc plate during the contraction and extension of the spring three. The striking action can bring vibration to the wrench on one side of the arc plate, improve the completion rate of the wrench flipping, avoid the wrench getting stuck in the material passing area, and cause the subsequent wrench to be blocked, thereby ensuring the flipping of the wrench.

At this time, the rotation will be synchronously transmitted to the driven wheel 2 through the setting of the synchronous belt 2. The driven wheel 2 will drive the connecting rod 1 and the bevel gear 1 to rotate. At this time, the bevel gear 2 engaged with the bevel gear 1 will achieve synchronous rotation, and the rotation of the bevel gear 2 will drive the connecting rod 2 and the eccentric wheel 1 to rotate.

[0018] The present invention is further configured as follows: the linkage component two includes a connecting rod four, the surface of the connecting rod four is fixedly sleeved with an eccentric wheel two, one end of the connecting rod four passes through one side of the shell and is fixedly sleeved with a bevel gear four, the surface of the bevel gear four is meshed with a bevel gear three, the interior of the bevel gear three is fixedly sleeved with a connecting rod three, the surface of the connecting rod three is rotatably connected to a support plate two fixedly connected to one side of the shell through a bearing, one end of the connecting rod three is fixedly sleeved with a driven wheel three, one end of the blanking component is fixedly sleeved with a driving wheel three, and the surface of the driven wheel three is sleeved with a synchronous belt three sleeved with the surface of the driving wheel three.

[0020] The two gears are connected by a plurality of gears, and the two gears are connected by a plurality of gears, and the two gears are connected by a plurality of gears.

[0021] By adopting the above technical solution, during the use of the transmission component 2, it will be driven by the operation of the linkage component 1. During the rotation of the connecting rod 2, the transmission wheel 4 will be driven to rotate, and through the cooperation of the transmission wheel 4 and the transmission belt 4, the rod body 1 on the rear side of the shell will be driven to rotate.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. The present invention sandblasts the wrench by the first sandblasting assembly as the loading assembly transfers the wrench before the wrench is sandblasted. The wrench is then flipped through the unloading assembly and sandblasted by the second sandblasting assembly. This process flips the wrench so that the front, back, and sides of the wrench are all sandblasted. The sandblasted wrench is manually unloaded by a worker at one end of the second conveyor belt, or a collection basket is placed at the other end of the second conveyor belt. The sandblasting device saves manpower. During the sandblasting of the wrench, only one person is required to arrange the loading of the wrench in an orderly manner, which is different from the inconvenience of manual flipping and hand-held sandblasting. This saves the company's sandblasting costs. At the same time, the striking assembly reciprocates to strike the curved plate.

[0026] 2. The present invention ensures the uniformity of sandblasting by setting two adjacent fixed brackets 1 at different angles on the surface of a fixed rod 1 and two adjacent fixed brackets 2 at different angles on the surface of a fixed rod 2 during the sandblasting of the wrench, thereby reducing the repeated sandblasting area during the sandblasting of the wrench and increasing the uniformity of sandblasting. At the same time, the operating equipment of the sandblasting structure is saved, and the subsequent operation is realized by sharing a driving device with the transmission structure. The maintenance cost of the rotating motor is reduced, and the time cost required for maintenance is further saved, which improves the convenience of using the sand blasting device. At the same time, the sand cleaning component will hit the bottom of the conveyor belt 1 and the conveyor belt 2, helping the conveyor belt 1 and the conveyor belt 2 that have passed the wrench to be hit and the gravel stuck or stuck on their surfaces can be knocked off. The operation of the loading component and the unloading component causes the gravel on the surface of the conveyor belt 1 and the conveyor belt 2 to be brought to the outside of the shell, thereby causing waste of gravel and pollution to the outside of the shell, thereby ensuring the recovery rate of gravel.

Both ends of the second fixing rod 4021 are fixedly sleeved with a torsion spring 4025, and the other end of the torsion spring 4025 is fixedly connected to the inner side of the shell 101. Before the wrench is sandblasted, as the loading assembly 201 transfers the wrench, the wrench is sandblasted by the sandblasting assembly 401, and then the wrench is set through the setting of the flipping structure 3, so that the flipped wrench is then transferred through the unloading assembly 202. The wrench is sandblasted by the sandblasting assembly 402, and the flipping of the wrench is realized through this link. The front, back, and sides of the wrench are all sandblasted, and the sandblasted wrenches are manually unloaded by a worker at one end of the conveyor belt 2023, or a collection box is placed at one end of the conveyor belt 2023. This sandblasting device saves manpower. During the sandblasting of the wrenches, only one person is required to arrange the loading of the wrenches in a regular manner, which is different from the inconvenience of existing manual flipping and hand-held sandblasting, saving the company's sandblasting costs. At the same time, the striking component 904 will perform a reciprocating striking action on the curved plate 303. This striking action can cause vibration to the wrench on one side of the curved plate 303, thereby improving the completion rate of the wrench flipping, preventing the wrench from getting stuck in the material passing area 306 and causing blockage of subsequent wrenches, and ensuring the flipping of the wrench.

The handle 103 is convenient for opening and using with the door body 102, and can be seen through the visual window. The setting of 107 makes it easy to check the sandblasting situation inside the shell 101. The sand storage area 106 is convenient for accumulating the sand and gravel discharged by sandblasting, and can be connected to the external air supply equipment through the pipeline 104, and the material control valve 105 can be used to discharge the material, so as to reuse the accumulated sand and gravel. The guide plate 8 can guide the sand and gravel missed by the feeding component 201, and its design of tilting to both sides can guide the sand and gravel to the front and back sides of the sand storage area 106, and the excess sand and gravel of the unloading component 202 can be accumulated in the middle of the sand storage area 106. The setting of the guide plate 8 ensures the uniformity of the accumulation of sand and gravel inside the sand storage area 106.

The arc area 1 302 matches the curvature of the transmission roller 2 2012, and the arc area 2 304 will facilitate the transfer of the turned wrench to the conveyor belt 2 2023. The material passing area 306 cooperates with the wrench for circulation, and the side plate 305 limits the wrench to avoid unpredictable angle changes of the wrench inside the material passing area 306.

A clip 1 9015 that cooperates with the clip 2 9016 and is engaged with the clip 1 9016 is provided on both sides of the interior of the supporting plate 9013. The bottom of the clip 1 9015 is fixedly installed with an insertion rod 9014 that passes through both sides of the supporting plate 9013. The surface of 14 is fixedly sleeved with a spring 1 9017 fixedly connected to the inner part of the supporting plate 9013. The striking block 9011 contacts the bottom of the conveyor belt 1 2013 and the conveyor belt 2 2023 through the contact pad 9012, and through the use of the reciprocating component 902 and the transmission component 2 903, the conveyor belt 1 2013 and the conveyor belt 2 2023 are struck back and forth, so that the conveyor belt 1 2013 and the conveyor belt 2 2023 that have passed the wrench can be struck off the gravel stuck or stuck on their surfaces. The sand will be guided by the guide plate 8 and finally accumulated in the sand storage area 106. At the same time, after the contact pad 9012 and the striking block 9011 are worn out after long-term use, the rods 9014 on both sides of the support plate 9013 will be pressed, so that the rods 9014 will be retracted into the inside of the support plate 9013 through the cooperation of the spring 1 9017. The movement of the rod 9014 will drive the buckle 1 9015 to move. At this time, the engagement between the buckle 1 9015 and the buckle 2 9016 is cancelled, so that the striking block 9011 can be removed and then released. By applying force to the insertion rod 9014, the spring 1 9017 drives the insertion rod 9014 back to its initial position.

The surface of the sliding rod 9042 is fixedly sleeved with a spring 9044 that is fixedly connected to the interior of the block 9041. The two ends of the sliding rod 9042 are respectively fixedly mounted with a contact head 9043 and a contact block 9045. The bottom of the contact head 9043 is provided with an eccentric wheel 9046. When the eccentric wheel 9046 is rotated by the operation of the transmission assembly 903, the eccentric wheel 9046 will contact the contact block 9045. The spring 3044 is pressed against the contact head 9043 to squeeze and hit the fixed blocks 308 on both sides of the arc plate 303, and completes a set of reciprocating striking actions on the arc plate 303 during the contraction and extension of the spring 3044. The striking action can bring vibration to the wrench on one side of the arc plate 303, thereby improving the completion rate of the wrench flipping, avoiding the wrench from getting stuck in the material passing area 306, causing the subsequent wrench to be blocked, and ensuring the flipping of the wrench.

The fixing ring 7 supports and fixes the rotating motor 6 and cooperates with the rotating motor 6 for normal operation.

[0052] Brief description of working principle: Before sandblasting the wrench, the wrench is first placed neatly on the surface of the loading assembly 201 by manual labor. The worker places the head and tail of the wrench toward the transmission roller 1 2011 and the transmission roller 2 2012 respectively. The relative length of the wrench on the surface of the conveyor belt 1 2013 can be as shown in the attached figure. Figure 11As shown in the figure, as the rotating motor 6 runs, it will drive the transmission roller 2011 to rotate, the support plate 2014 supports the transmission roller 2011 and cooperates with it to rotate smoothly through the bearing. The conveyor belt 2013 is convenient for transmitting the rotation of the transmission roller 2011 to the transmission roller 2 2012, so that the wrench is transmitted on the surface of the conveyor belt 2013. During the transmission of the conveyor belt 2013, it will be sandblasted by the sandblasting component 401. The top sandblasting head 4013 and the side sandblasting head 4014 are connected to the external sand supply equipment and the air supply equipment, so that the top of the wrench and the side close to the sandblasting component 401 are sandblasted. Then the wrench is gradually transmitted to the other end of the conveyor belt 2013. At this time The setting of the limit plate 301 and the arc plate 303 will flip the wrench transmitted from the conveyor belt 2013. The rubber part 307 is elastic and prevents one end of the wrench from contacting the inner side of the shell 101 to cause jamming. At this time, although the wrench is in contact with the rubber part 307, the wrench can be put back on track through its elastic characteristics. The arc area 1 302 matches the curvature of the transmission roller 2 2012, and the arc area 2 304 will facilitate the transfer of the flipped wrench to the conveyor belt 2 2023. The material passing area 306 cooperates with the wrench for circulation. The side plate 305 limits the wrench to prevent the wrench from having unpredictable angle changes inside the material passing area 306. At this time, the flipped wrench will be transferred by the arc area 2 304 and will not fall. To the surface of the conveyor belt 2023, through the setting of the transmission component 1 203, when the transmission roller 1 2011 and the driving wheel 1 2031 rotate, the conveyor belt 1 2013 will be used to transmit the rotation to the driven wheel 1 2032 and the transmission roller 3 2021, thereby realizing the operation of the blanking component 202. At this time, the wrench is continuously transmitted through the conveyor belt 2 2023, and the wrench passes through the sandblasting component 2 402. At the same time, the top sandblasting head 2 4023 and the side sandblasting head 2 4024 are also connected to the external sand supply equipment and the air supply equipment, and the top of the wrench and the side close to the sandblasting component 2 402 are sandblasted. Through this link, the wrench is flipped, so that the front, back and sides of the wrench are all sandblasted. The wrench after sandblasting will be continuously transferred through the conveyor belt 2023 and manually unloaded by the worker at one end of the conveyor belt 2023, or a collection box will be placed at the bottom of one end of the conveyor belt 2023 to facilitate collection. The sandblasting device saves manpower loss. During the sandblasting of the wrench, only one person is required to arrange the loading of the wrench in a regular manner, which is different from the inconvenience of existing manual turning and hand-held sandblasting, thus saving the sandblasting cost for the enterprise. At the same time, the transmission component 2 903 will be driven by the operation of the linkage component 1 501. During the rotation of the connecting rod 2 5018, the transmission wheel 4 9039 will be driven to rotate, and through the cooperation of the transmission wheel 4 9039 and the transmission belt 4 90310, the rod body 1 9031 on the rear side of the shell 101 will be driven to rotate.At this time, through the cooperation of the transmission wheel 1 9033 and the transmission belt 1 9035, the two rod bodies 1 9031 will be rotated, thereby realizing the reciprocating operation of the striking assembly 904. When the eccentric wheel 4 9046 is rotated by the operation of the transmission assembly 2 903, the eccentric wheel 4 9046 will squeeze the contact block 4 9045, so that the contact block 4 9045 drives the sliding rod 2 9042 to move longitudinally inside the block 9041. At the same time, the spring 3 9044 cooperates with the movement of the sliding rod 2 9042 to shrink. The sliding rod 2 9042 will drive the contact head 9043 to squeeze and strike the fixed blocks 308 on both sides of the arc plate 303, and complete a set of The reciprocating striking action of the arc plate 303 can bring vibration to the wrench on one side of the arc plate 303, thereby improving the completion rate of the wrench flipping, preventing the wrench from getting stuck in the material passing area 306 and causing clogging of subsequent wrenches, thereby ensuring the flipping of the wrench. In addition, the guide plate 8 can guide the gravel missed by the feeding component 201, and through its design of tilting to both sides, the gravel is guided to the front and rear sides of the sand storage area 106, while the excess gravel of the discharge component 202 can be accumulated in the middle of the sand storage area 106. The setting of the guide plate 8 ensures the uniformity of the accumulation of gravel in the sand storage area 106, which is convenient for the subsequent discharge and use of gravel, further saving the sandblasting cost of the sandblasting device and facilitating the recycling and reuse of gravel.

During the sandblasting of the wrench, the sandblasting component 1 401 will realize the rocker movement through the linkage component 1 501, and the sandblasting component 2 402 will realize the rocker movement through the linkage component 2 502. In addition, the two adjacent fixed brackets 1 4012 are arranged at different angles on the surface of the fixed rod 1 4011, and the two adjacent fixed brackets 2 4022 are arranged at different angles on the surface of the fixed rod 2 4021, thereby ensuring the uniformity of the sandblasting. The repeated sandblasting area in the sandblasting of the wrench is reduced, the uniformity of the sandblasting is increased, and the operating equipment of the sandblasting structure 4 is saved. By sharing a driving device with the transmission structure, the subsequent maintenance cost of the rotating motor 6 is reduced, and the time cost required for maintenance is further saved, which brings convenience to the use of the sandblasting device. At the same time, the sand cleaning component 901 will hit the bottom of the conveyor belt 1 2013 and the conveyor belt 2 2023, helping the conveyor belt 1 2013 and the conveyor belt 2 2023 that have conveyed the wrench to be hit and fall off the gravel stuck or stuck on their surfaces. The surface passes through the operation of the loading component 201 and the unloading component 202, resulting in the gravel on the surface of the conveyor belt 1 2013 and the conveyor belt 2 2023 being brought to the outside of the shell 101, thereby causing waste of gravel and pollution to the outside of the shell 101, ensuring the recovery rate of gravel.

The gravel after being knocked off will be guided by the guide plate 8 and finally accumulated in the sand storage area 106. At the same time, after the contact pad 9012 and the striking block 9011 are worn out after long-term use, the rods 9014 on both sides of the support plate 9013 will be pressed, so that the rods 9014 can be pushed through the springs. The spring 9017 cooperates with the first one 9017 and retracts into the inside of the supporting plate 9013. The movement of the insertion rod 9014 will drive the buckle 1 9015 to move. At this time, the clamping connection between the buckle 1 9015 and the second buckle 9016 is cancelled, so that the striking block 9011 can be removed. Then, the force applied to the insertion rod 9014 is released, and the spring 1 9017 drives the insertion rod 9014 back to the initial position. When the striking block 9011 needs to be reinstalled, the buckle 2 9016 at the bottom of the striking block 9011 is inserted into the supporting plate 9013. Inside, the support plate 9013 is then pressed downward, causing the first clip 9015 and the second clip 9016 to engage with each other, completing the replacement of the striking block 9011. This increases the convenience of operation in this process. At the same time, the shape of the support plate 9013 prevents sand and gravel from accumulating on the top of the support plate 9013. By sharing a drive device with the transmission structure, the subsequent maintenance cost of the rotating motor 6 is reduced, and the time cost required for maintenance is further saved, which brings convenience to the use of the sandblasting device.
