Description

Technical Field

[0001] The present application relates to the field of wind power tower workpiece processing, and in particular to a tower flange rotary self-circulating shot blasting machine. Background Art

[0002] With the development of sustainable energy, wind energy, as an environmentally friendly renewable energy, can generate electricity sustainably using wind power. Wind turbine tower is the tower pole of wind power generation, which mainly plays a supporting role in wind turbine generator sets and absorbs the vibration of the unit. The flange of the wind turbine tower is a connecting component, which is mainly used to fix different parts of the tower together to form a complete wind turbine generator structure.

[0003] Before the wind tower is connected by flange, the flange must be shot blasted. At present, the flange is shot blasted by shot blasting machine. In the shot blasting cleaning machine market, the most widely used are hook-type shot blasting cleaning machine and squirrel cage shot blasting cleaning machine. However, these two traditional shot blasting cleaning methods require manual loading and unloading of workpieces in the cage, which is time-consuming and labor-intensive. In addition, a large amount of smoke and dust will be generated during the cleaning process to pollute the environment. There are problems such as low cleaning efficiency and easy pollution of the environment. Summary of the invention

[0004] In order to solve the problems of low cleaning efficiency and easy environmental pollution in the flange cleaning process, the present application provides a tower flange rotating self-circulating shot blasting machine.

[0005] The present application provides a tower flange rotating self-circulating shot blasting machine, which adopts the following technical solution:

[0006] A tower flange rotary self-circulating shot blasting machine comprises a conveying mechanism, wherein the conveying mechanism comprises a mobile platform, a conveying assembly and a clamping and positioning assembly, wherein the conveying assembly and the clamping and positioning assembly are both arranged on the mobile platform, wherein the mobile platform is used to carry the conveying assembly and the clamping and positioning assembly for movement, wherein the conveying assembly is used to convey the flange for rotation, and wherein the clamping and positioning assembly is used to clamp and position the flange on the conveying assembly; a shot blasting mechanism is arranged on one side of the conveying mechanism and is used for the mobile platform to deliver the flange on the conveying assembly; a recovery mechanism is arranged on one side of the shot blasting mechanism and is connected to the shot blasting mechanism, wherein the recovery mechanism comprises a lifting assembly and a separation assembly, wherein the lower end of the lifting assembly is connected to the lower end of the shot blasting mechanism and is used to recover the shot material thrown by the shot blasting mechanism, wherein the upper end of the lifting assembly is connected to the separation assembly, wherein the separation assembly is used to separate the intact shot material and the broken shot material in the shot material, and wherein the separation assembly is connected to the upper end of the shot blasting mechanism and is used to replenish the shot material in the shot blasting mechanism, and to separate the shot material into coarse and fine particles while absorbing the smoke and dust in the separation process.

[0007] By adopting the above technical solution, when the flange is cleaned, the flange is fixed on the mobile platform through the clamping and positioning assembly, so that the mobile platform drives the flange to move to the shot blasting mechanism. Then the flange is conveyed on the mobile platform by the conveying assembly to rotate, so that the flange can rotate while being shot blasted in the shot blasting mechanism, so as to shot blast the entire flange. After that, the complete shot and the broken shot after the shot blasting are collected by the recovery mechanism, and the lifting assembly is used to lift them to the separation assembly to separate the complete shot and the broken shot, so that the recovered complete shot can be reused and enter the shot blasting mechanism for shot blasting, so that the shot is circulated in the shot blasting mechanism, and in the process of shot blasting, the separation assembly absorbs the smoke generated during and after the shot blasting process, so as to realize the automatic loading and operation of the workpiece while absorbing a large amount of smoke, thereby improving the cleaning efficiency and reducing the pollution to the environment.

[0008] Optionally, the lifting assembly includes: a lifting box, vertically arranged on the side of the shot blasting mechanism away from the conveying mechanism, the lifting box is provided with a discharge port, the discharge port is arranged at the upper end of the lifting box, and the lifting box is connected with the separation assembly through the discharge port; a sprocket, rotatably arranged at the upper and lower ends of the lifting box; a chain, meshingly sleeved on the sprocket and rotating in the lifting box; a plurality of bucket boxes and spaced apart on the side of the chain away from the sprocket; a lifting motor, arranged on the lifting box to drive the sprocket to rotate.

[0009] By adopting the above technical solution, when the shot materials after shot blasting are collected, the sprocket is driven to rotate by the lifting motor, and the sprocket drives the chain to rotate, thereby driving multiple buckets on the chain to reciprocate from bottom to top, so as to scoop up the shot materials at the bottom of the lifting box and put them into the discharging port from the discharge port, so that the shot materials after shot blasting are lifted from the bottom and enter the separation component for separation.

[0010] Optionally, the separation component includes: a separation box, which is arranged on the lifting box, and a feed port is provided on the separation box, and the feed port is located below the discharge port; a material guide plate, which is arranged on the separation box and located below the feed port, and the material guide plate is used to guide the pill material from the feed port; a partition plate, which is arranged in the separation box and divides the separation box into a coarse material chamber and a fine material chamber, the material guide plate is located in the coarse material chamber, and a connecting port connecting the coarse material chamber and the fine material chamber is provided on the partition plate, and the connecting port is used to allow the fine material separated in the coarse material chamber to enter the fine material chamber; a fan, which is arranged on a side of the separation box away from the lifting box and connected with the fine material chamber, and a dust bag is provided on a side of the fan away from the separation box, and the fan is used to generate suction to suck the fine material in the coarse material chamber after passing through the material guide plate from the connecting port into the fine material chamber, and to suck away the smoke and dust in the separation box.

[0011] By adopting the above technical solution, when the pellets are separated and processed, the pellets enter the separation box from the feed port and are introduced into the separation box through the guide plate. As the pellets fall downward on the guide plate, the fan starts to draw air from the coarse material chamber to the fine material chamber, so that in the process of falling, the complete pellets fall into the coarse material chamber due to their heavy weight, and the broken pellets, which are lighter in weight, enter the fine material chamber through the connecting port under the action of wind, and the finer pellet powder enters the dust collecting bag through the fan, so as to separate the pellets entering the separation box into coarse and fine, and absorb the smoke generated during the separation process, thereby reducing pollution to the external environment.

[0012] Optionally, a receiving hopper is provided in the separation box, and the receiving hopper is arranged above the material guide plate and located in the feed port. The end of the receiving hopper away from the lifting box has an opening, and the end of the receiving hopper away from the opening is arranged close to the hopper box for receiving the pill material from the discharge port and pouring it onto the material guide plate.

[0013] By adopting the above technical solution, when the pills are poured into the separation box through the bucket box, the bucket box is rotated by the chain and then flipped over and poured into the receiving hopper in the feed port, so that more pills can be introduced onto the guide plate after being received by the receiving hopper, thereby reducing the amount of pills that fall back into the lifting box when the bucket box is flipped over.

[0014] Optionally, the separation assembly also includes a transmission member, which is connected to the material receiving hopper, and the material receiving hopper is slidably set on the separation box. The material receiving hopper slides in the feed port in a horizontal direction, and one end of the material receiving hopper located in the separation box is connected to a first spring, and one end of the first spring away from the material receiving hopper is fixed to the separation box. When the first spring is in a natural state, one end of the material receiving hopper away from the first spring extends from the feed port into the discharge port and is located on one side of the moving path of the hopper box, and the transmission member is used to drive the material receiving hopper to slide between two adjacent hopper boxes as the sprocket rotates.

[0015] By adopting the above technical solution, when the bucket box guides the pellets into the receiving hopper, the sprocket drives the chain and the bucket box to rotate, and the sprocket also drives the receiving hopper to slide horizontally toward the bucket box through the transmission member, so that the first spring is stretched, so that the end of the receiving hopper away from the first spring slides into between two adjacent bucket boxes, further shortening the distance between the bucket box and the receiving hopper, so that the receiving hopper can receive more pellets. After the transmission member is reset, the receiving hopper slides into the separation box under the pulling force of the first spring, and then drives the receiving hopper to slide out between the adjacent bucket boxes, so that the bucket box continues to rotate downward with the chain, thereby increasing the receiving hopper's receiving amount while avoiding the receiving hopper from hindering the rotation of the bucket box.

[0016] Optionally, the transmission member includes: a transmission rod slidably arranged on the outer wall of the separation box, the sliding direction of the transmission rod is the same as the sliding direction of the receiving hopper, and the end of the transmission rod away from the lifting box passes through the separation box and is connected to the receiving hopper; an abutment block is arranged at the end of the transmission rod away from the receiving hopper; the sprocket is coaxially connected with a rotating shaft located outside the lifting box, and a plurality of driving blocks are spaced apart on the peripheral wall of the rotating shaft, and the driving block is used to abut the abutment block toward the side wall of the separation box, and the abutment interval time between two adjacent driving blocks and the abutment block is the same as the time when two adjacent bucket boxes pass through the receiving hopper.

[0017] By adopting the above technical solution, when the sprocket drives the chain and the bucket box to rotate, the sprocket also drives the driving block to rotate, and the driving block rotates with the bucket box. When the end of the receiving hopper is facing between adjacent bucket boxes, the driving block and the abutting block abut against the side wall of the separation box to abut the abutting block to move away from the separation box, and then drive the transmission rod to move away from the separation box, and then drive the receiving hopper to slide out of the separation box and enter between adjacent bucket boxes. After the bucket box at the top of the lifting box flips to guide the pellets into the receiving hopper, the driving block slides over the abutting block, and after the transmission rod loses the abutting force, the receiving hopper slides out of the adjacent bucket boxes under the pulling force of the first spring, and drives the transmission rod and the abutting block to slide in the direction close to the separation box and reset. After reciprocating in this way, the receiving hopper is located between the adjacent bucket boxes when each bucket box is located at the top of the lifting box to receive the pellets, so that the receiving hopper receives a large amount of pellets, thereby improving the receiving efficiency of the receiving hopper.

[0018] Optionally, a rotating column is provided on the transmission rod, and the rotating column slides through the side wall of the separation box and is rotatably connected to the receiving hopper. A through hole is opened on the side wall of the separation box for the rotating column to slide in a horizontal direction. A torsion spring is also sleeved on the rotating column, and the torsion spring acts on the receiving hopper to keep the receiving hopper sliding in the horizontal direction.

[0019] By adopting the above technical solution, when the bucket box rotates downward and abuts against the receiving bucket that has no time to reset, the downward force of the bucket box acts on the receiving bucket, and the receiving bucket rotates on the transmission rod through the rotating column, and due to the torsion of the torsion spring, the bucket box pushes the receiving bucket downward so that after the receiving bucket rotates, the receiving bucket can be reset after separating from the bucket box, so that the receiving bucket can slide between the two adjacent bucket boxes again under the drive of the transmission rod, so that when the bucket box collides with the receiving bucket, the bucket box can rotate normally and the receiving bucket can be reset to continue to receive the pill material.

[0020] Optionally, the bottom wall of the material receiving hopper has tooth patterns, and one end of the material guide plate close to the material receiving hopper slides against the tooth patterns of the material receiving hopper, and the material guide plate is elastic.

[0021] By adopting the above technical solution, when the receiving hopper slides between adjacent hopper boxes to receive the pills, the receiving hopper continuously slides and abuts against the guide plate through the teeth, so that the guide plate shakes due to its own elastic force under the continuous abutment of the teeth, so that the shaking guide plate transports the pills downward evenly and at a uniform speed, so as to reduce the range of the pills splashing along the guide plate, which helps to separate the coarse material and the fine material by wind force.

[0022] Optionally, the material guide plate includes a first material plate that is slidably abutted against the material receiving hopper and a second material plate connected to an end of the first material plate away from the material receiving hopper, the first material plate and the second material plate form an obtuse angle, and the height of the end of the second material plate away from the first material plate is flush with the top wall of the connecting port on the partition plate.

[0023] By adopting the above technical solution, when the receiving hopper pours the pills onto the guide plate, the first material plate slides against the tooth patterns on the bottom wall of the receiving hopper to drive the second material plate to vibrate, and the pills vibrate toward the partition plate under the vibration of the second material plate, and part of the pills are blocked by the partition plate and fall vertically downward, so that the pills shaken off the guide plate all fall vertically downward, so that the suction force of the fan can suck the fine materials falling vertically downward into the fine material chamber, thereby improving the accuracy of coarse and fine separation of the pills.

[0024] Optionally, a dust cover is provided on the side wall of the fan located in the separation box, the dust cover is provided with a plurality of through holes, the dust cover is slidably mounted on the fan, and a plurality of second springs are provided on the dust cover, one end of the second spring away from the dust cover is provided on the fan, an abutment rod is slidably provided on the inner wall of the separation box, one end of the abutment rod abuts against an end of the second material plate away from the first material plate, and the other end of the abutment rod abuts against the dust cover.

[0025] By adopting the above technical scheme, when the fine material of the shot material enters the fine material chamber, part of the fine material falls into the fine material chamber, and then the smaller powder gathers on the dust cover, and the air is sucked away through the through hole. After long-term use, more smoke and dust accumulate on the dust cover, which is easy to block the through hole and reduce the suction force of the fan. Therefore, under the shaking of the guide plate, the guide plate continuously abuts the abutment rod, so that the abutment rod abuts toward the dust cover in the horizontal direction, so that the abutment rod abuts the dust cover to compress the second spring, and then the dust cover is reset under the second spring and abuts the abutment rod to slide toward the guide plate to reset, so that the abutment rod continuously slides back and forth in the horizontal direction and abuts the dust cover to continuously press up and down on the fan to bounce up, so that the abutment rod abuts the dust cover to achieve the bounce, and the smoke and dust accumulated on the dust cover is shaken off into the fine material chamber.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The shot material is circulated in the shot blasting mechanism. During the shot blasting process, the separation component absorbs the smoke generated during and after the shot blasting process, realizing the automatic loading and operation of the workpiece while absorbing a large amount of smoke, thereby improving the cleaning efficiency and reducing pollution to the environment.

[0028] 2. The receiving hopper slides into the separation box under the pulling force of the first spring, and then drives the receiving hopper to slide out between adjacent hopper boxes, so that the hopper boxes continue to rotate downward with the chain, thereby increasing the material receiving capacity of the receiving hopper and avoiding the receiving hopper from hindering the rotation of the hopper boxes.

[0029] 3. When each hopper box is located at the top of the lifting box, the receiving hopper is located between adjacent hopper boxes to receive the pellets, so that the receiving hopper can receive a large amount of pellets, thereby improving the receiving efficiency of the receiving hopper.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The present application embodiment discloses a tower flange rotating self-circulating shot blasting machine. Figure 1 A tower flange rotary self-circulating shot blasting machine includes a conveying mechanism 1, a shot blasting mechanism 2 and a recovery mechanism 3. The conveying mechanism 1 includes a mobile platform 11, a conveying assembly 12 and a clamping and positioning assembly 13. The conveying assembly 12 and the clamping and positioning assembly 13 are both arranged on the mobile platform 11. The mobile platform 11 is used to carry the conveying assembly 12 and the clamping and positioning assembly 13 for movement. The conveying assembly 12 is used to rotate the conveying flange. The clamping and positioning assembly 13 is used to clamp and position the flange on the conveying assembly 12. The shot blasting mechanism 2 is arranged on one side of the conveying mechanism 1 and is used by the mobile platform 11 to feed the flange on the conveying assembly 12. The recovery mechanism 3 is arranged on one side of the shot blasting mechanism 2 and is connected to the shot blasting mechanism 2. The recovery mechanism 3 includes a lifting assembly 31 and a separation assembly 32. The lower end of the lifting assembly 31 is connected to the lower end of the shot blasting mechanism 2, and is used to recover the shot material thrown by the shot blasting mechanism 2. The upper end of the lifting assembly 31 is connected to the separation assembly 32. The separation component 32 is used to separate the intact shot and the broken shot in the shot, and the separation component 32 is connected to the upper end of the shot blasting mechanism 2, and is used to replenish the shot in the shot blasting mechanism 2, and separate the coarse and fine shot and absorb the smoke and dust in the separation process.

[0037] In this embodiment, a roller is provided at the bottom of the mobile platform 11 , and the roller is driven to rotate by a motor so that the roller moves in the track 211 to drive the conveying assembly 12 and the clamping and positioning assembly 13 to approach or move away from the shot blasting mechanism 2 .

[0038] Exemplarily, four fixed columns 111 are fixedly connected to the mobile platform 11, and the conveying assembly 12 is arranged on the fixed column 111. The conveying assembly 12 includes a conveying roller 121 rotatably connected to the top of the fixed column 111, and a motor arranged on the fixed column 111 to drive the conveying roller 121 to rotate. The extension lines of the conveying rollers 121 on each fixed column 111 pass through the same center of a circle, so that the flange on the mobile platform 11 can be driven to rotate by the rotation of the conveying rollers 121. It should be noted that the conveying rollers 121 are located at Figure 1 The flange is under the bearing and rolls against the flange.

[0039] Exemplarily, the clamping and positioning assembly 13 includes a clamping plate 131 at one end arranged at the top of the fixed column 111, and the clamping plates 131 are respectively located at both ends of the conveying roller 121, and one of the clamping plates 131 is threadedly connected to a screw rod, so that one of the clamping plates 131 can be controlled to move closer to or away from the other clamping plate 131 by rotating the screw rod, thereby limiting the flange on the conveying roller 121, so that the flange can rotate stably on the conveying roller 121.

[0040] In some other embodiments, the flange can be placed horizontally on the mobile platform 11 and rotated, and can also be welded to the tower and the tower can be placed vertically, so that the clamp 131 clamps the inner and outer walls of the flange welded to the tower, and then the flange welded to the tower is also transported by the conveying roller 121 to facilitate shot blasting or sand blasting of the flange.

[0041] In some embodiments, the shot blasting mechanism 2 has a connecting hopper 21, and the connecting hopper 21 is connected to the lower end of the lifting assembly 31 at one end away from the shot blasting mechanism 2, so as to transport the shot blasted by the shot blasting mechanism 2 to the lower end of the lifting assembly 31. A track 211 is arranged below the connecting hopper 21, that is, the shot blasting mechanism 2 is located between the conveying mechanism 1 and the recovery mechanism 3. The shot blasting mechanism 2 includes a shot blasting chamber 22 located on the lifting assembly 31, a shot blaster 23 arranged on the shot blasting chamber 22, and a shot storage chamber 24 arranged on the shot blasting chamber 22. A cleaning port 221 for the flange to enter is provided on the shot blasting chamber 22, and a brush is installed in the cleaning port 221, which can brush off the debris on the flange on the one hand, and prevent the shot in the shot blasting chamber 22 from flying out on the other hand.

[0042] It should be noted that the width of the cleaning port 221 in the vertical direction is greater than 600 mm to meet the needs of shot blasting and sand blasting for flanges of different models.

[0043] In some other embodiments, a movable opening and closing plate may also be provided in the cleaning port 221, and the opening and closing plate slides up and down so that the opening and closing plate seals the cleaning port after the flange is sent in, and only the flange can rotate, so that the opening and closing plate can cover the cleaning port 221 after flanges of different widths are sent in, thereby adapting to flanges of different widths for shot blasting or sand blasting, which helps to improve the sealing of the flange during shot blasting or sand blasting.

[0044] Exemplarily, there are four shot blasters 23, which are tilted toward the flange in the shot blasting chamber 22 to cover the upper and lower side walls, the inner wall and the outer wall of the flange. Each shot blaster 23 is connected to a pipeline, and the other end of the pipeline is connected to the shot storage chamber 24, so as to replenish the shot materials to the shot blaster 23 in time.

[0045] In some embodiments, the lifting assembly 31 is located on the side of the shot blasting chamber 22 away from the mobile platform 11, and the separation assembly 32 is fixed to the upper end of the lifting assembly 31. The connecting hopper 21 is tapered and connected to the bottom of the lifting assembly 31 to feed the shot materials after the shot blasting into the bottom of the lifting assembly 31, so that the lifting assembly 31 lifts the shot materials and separates them through the separation assembly 32, and then feeds the complete shot materials into the shot storage chamber 24 again, so that the shot blaster 23 can perform shot blasting again, thereby realizing the circulation of the shot materials between the shot blasting chamber 22 and the shot storage chamber 24.

[0046] In some embodiments, the connecting hopper 21 is elastic, and the shot blasting chamber 22 is slidably connected to the side wall of the lifting assembly 31 toward the shot blasting chamber 22 in the vertical direction, so that the shot blasting chamber 22 is suitable for flange shot blasting or sand blasting at different heights, and the shot material after shot blasting can still be transported to the bottom of the lifting assembly 31 after passing through the connecting hopper 21.

[0047] For example, Figure 1 and Figure 2 As shown, a baffle 222 is provided inside the shot blasting chamber 22, and the baffle 222 divides the space inside the shot blasting chamber 22 into a chamber for flange shot blasting and a mounting chamber 223. A motor 224 is installed in the mounting chamber 223, and the motor 224 is connected to a gear 225, and a rack 228 is fixedly connected to the side wall of the lifting assembly 31 facing the shot blasting chamber 22, and the rack 228 extends in the vertical direction, so that after the motor 224 drives the gear 225 to rotate, the shot blasting chamber 22 is driven to slide along the length direction of the rack 228 through the reaction force of the rack 228.

[0048] For example, a dovetail column 227 is fixedly connected to the side wall of the lifting assembly 31 facing the shot blasting chamber 22, and a dovetail groove is formed on the dovetail column 227. The dovetail column 227 is parallel to the rack 228, and a groove for the dovetail column 227 to fit into is formed in the side wall of the shot blasting chamber 22. The notch of the groove extends in the vertical direction, and a dovetail bar 226 is connected to the bottom of the groove. The dovetail bar 226 matches the dovetail groove on the dovetail column 227, so that the shot blasting chamber 22 can slide along the side wall of the lifting assembly 31 in the vertical direction through the cooperation of the dovetail bar 226 and the dovetail column 227, and at the same time, the shot blasting chamber 22 is restricted from being separated from the lifting assembly 31, so that the shot blasting chamber 22 can be driven up and down by the motor 224.

[0049] For example, Figure 1 and Figure 3 As shown, the lifting assembly 31 includes a lifting box 311, a sprocket 312, a chain 313, a bucket box 314 and a lifting motor 315. The lifting box 311 is vertically arranged on the side of the shot blasting mechanism 2 away from the conveying mechanism 1. A discharge port 3111 is provided on the lifting box 311. The discharge port 3111 is arranged at the upper end of the lifting box 311, and the lifting box 311 is connected to the separation assembly 32 through the discharge port 3111. The sprocket 312 is rotatably arranged at the upper and lower ends of the lifting box 311. The chain 313 is meshed and sleeved on the sprocket 312 and rotates in the lifting box 311. The bucket box 314 has a plurality of bucket boxes and is spaced apart on the side of the chain 313 away from the sprocket 312. The lifting motor 315 is arranged on the lifting box 311 to drive the sprocket 312 to rotate.

[0050] It can be understood that the rack 228 and the dovetail column 227 are both located on the side wall of the lifting box 311 facing the shot blasting chamber 22.

[0051] For example, the lifting motor 315 is coaxially connected to the sprocket 312 at the bottom of the lifting box 311, and the sprocket 312 drives the chain 313 and the bucket box 314 to move upward. Figure 2 The clockwise rotation shown means that the chain 313 and the bucket box 314 close to the separation component 32 rotate downward, so that the bucket box 314 can scoop up the pills when it rotates to the bottom sprocket 312 of the lifting box 311, and pour the pills into the separation component 32 when the bucket box 314 is full of pills and rotates to the top sprocket 312 of the lifting box 311, thereby completing the lifting of the pills.

[0052] In some embodiments, the separation assembly 32 includes a separation box 321, a guide plate 322, a partition plate 323 and a fan 324. The separation box 321 is arranged on the lifting box 311, and a feed port 3211 is provided on the separation box 321, and the feed port 3211 is located below the discharge port 3111. The guide plate 322 is arranged on the separation box 321 and is located below the feed port 3211, and the guide plate 322 is used to guide the pellets from the feed port 3211. The partition plate 323 is arranged in the separation box 321, and divides the separation box 321 into a coarse material chamber 3212 and a fine material chamber 3213, and the guide plate 322 is located in the coarse material chamber 3212. A connecting port 3231 connecting the coarse material chamber 3212 and the fine material chamber 3213 is provided on the partition plate 323, and the connecting port 3231 is used for allowing the fine material separated in the coarse material chamber 3212 to enter the fine material chamber 3213, and the fan 324 is arranged on the side of the separation box 321 away from the lifting box 311 and is connected to the fine material chamber 3213, and a dust bag 3241 is provided on the side of the fan 324 away from the separation box 321, and the fan 324 is used for generating suction to suck the fine material in the coarse material chamber 3212 after passing through the guide plate 322 into the fine material chamber 3213 from the connecting port 3231, and to suck away the smoke and dust in the separation box 321.

[0053] It should be noted that the fan 324 can also be arranged on the side wall of the separation box 321 adjacent to the lifting box 311, that is, the fan 324, the dust bag 3241 and the pipe connecting the fan 324 and the dust bag 3241 are located on the side adjacent to the separation box 321 and the lifting box 311, so as to facilitate the shot blasting or sand blasting of the flange welded on the tower, and when the tower is placed vertically, the fan 324, the dust bag 3241 and the pipe connecting the fan 324 and the dust bag 3241 can be avoided from interfering with the flange and the tower that are being shot blasted or sand blasted.

[0054] In this embodiment, the feed port 3211 on the separation box 321 is connected with the discharge port 3111 on the lifting box 311, and the calibers of the feed port 3211 and the discharge port 3111 are the same. The lifting box 311 is completely closed, and only the discharge port 3111 is connected with the feed port 3211. The separation box 321 tapers close to the bottom wall of the lifting box 311, so that the bottom of the separation box 321 is an inclined bottom wall, and the inclined bottom wall is provided with an air inlet 3214, and a filter screen is fixed at the air inlet 3214. The fan 324 is fixed on the side wall of the separation box 321 away from the lifting box 311, so that after the fan 324 is started, air is sucked in from the filter screen of the air inlet 3214, and also from the discharge port 3111 and the feed port 3211, so that the crushed pills in the pills are sucked into the fine material chamber 3213. The fan 324 has a function of sucking finer pellets from the connecting port 3231 into the fine material chamber 3213, and another function of sucking finer smoke and dust into the dust collecting bag 3241, thereby removing dust.

[0055] Exemplarily, the partition plate 323 includes an upper partition plate 3232 and a lower partition plate 3233, wherein the upper partition plate 3232 forms a communication port 3231 between the lower partition plate 3233, and the partition plate 3232 and the lower partition plate 3233 are staggered in the vertical direction. The lower partition plate 3233 is closer to the fan 324 than the upper partition plate 3232. The height of the bottom of the upper partition plate 3232 is the same as the height of the bottom of the guide plate 322, so that after the guide plate 322 guides the pellets into the coarse material chamber 3212, the complete pellets can fall into the coarse material chamber 3212 through the blocking of the upper partition plate 3232 and the misalignment of the lower partition plate 3233, while the incomplete and finer pellets enter the fine material chamber 3213.

[0056] For example, a sieve plate 3234 is further provided in the fine material chamber 3213. The sieve plate 3234 is tiltedly arranged in the fine material chamber 3213. The higher end of the sieve plate 3234 is arranged close to the fan 324, and the lower end of the sieve plate 3234 is arranged at the bottom of the fine material chamber 3213, so as to further divide the fine material chamber 3213 into two chambers, one of which is adjacent to the coarse material chamber 3212 to collect medium-coarse pellets; and the other chamber is adjacent to the fan 324 to collect relatively fine pellets.

[0057] For another example, a pipe connected to the coarse material chamber 3212 is fixed at the bottom of the separation box 321, and the other end of the pipe is connected to the pill storage chamber 24, so that the recovered complete pills can be collected and reused. The bottom of the separation box 321 connected to the fine material chamber 3213 has a valve port to take out the finer pill powder in time.

[0058] In some embodiments, a receiving hopper 325 is provided in the separation box 321. The receiving hopper 325 is disposed above the guide plate 322 and in the feed port 3211. The receiving hopper 325 has an opening at one end away from the lifting box 311. The receiving hopper 325 is disposed close to the hopper box 314 at one end away from the opening, so as to receive the pellets from the discharge port 3111 and pour them onto the guide plate 322.

[0059] In this embodiment, the receiving hopper 325 slides in the feed port 3211 and the discharge port 3111, and the diameters of the feed port 3211 and the discharge port 3111 are both larger than the depth of the receiving hopper 325, so that the receiving hopper 325 can move in a small range in the vertical direction in both the separation box 321 and the lifting box 311.

[0060] In some embodiments, Figure 1 and Figure 4 As shown, the separation assembly 32 also includes a transmission member 326. The transmission member 326 is connected to the receiving hopper 325, and the receiving hopper 325 is slidably arranged on the separation box 321. The receiving hopper 325 slides in the feed port 3211 in the horizontal direction, and one end of the receiving hopper 325 located in the separation box 321 is connected to the first spring 3251. One end of the first spring 3251 away from the receiving hopper 325 is fixed to the separation box 321. In the natural state of the first spring 3251, one end of the receiving hopper 325 away from the first spring 3251 extends from the feed port 3211 into the discharge port 3111 and is located on one side of the moving path of the hopper box 314. The transmission member 326 is used to drive the receiving hopper 325 to slide between two adjacent hopper boxes 314 as the sprocket 312 rotates.

[0061] In this embodiment, the transmission member 326 is located outside the separation box 321. There are two first springs 3251, which are respectively located on both sides of the receiving hopper 325. One end of the first spring 3251 away from the receiving hopper 325 is fixed to the upper partition 3232, so that the receiving hopper 325 is driven by the pulling force of the first spring 3251 to slide in the separation box 321 and then reset. The bottom of the end of the receiving hopper 325 located outside the separation box 321 is designed to be arc-shaped, so that the receiving hopper 325 can slide smoothly between the separation box 321 and the lifting box 311.

[0062] In some embodiments, the transmission member 326 includes a transmission rod 3261 and an abutment block 3262. The transmission rod 3261 is slidably disposed on the outer wall of the separation box 321. The sliding direction of the transmission rod 3261 is the same as the sliding direction of the receiving hopper 325. The end of the transmission rod 3261 away from the lifting box 311 passes through the separation box 321 and is connected to the receiving hopper 325. The abutment block 3262 is disposed at the end of the transmission rod 3261 away from the receiving hopper 325. The sprocket 312 is coaxially connected with a rotating shaft 316 located outside the lifting box 311, and a plurality of driving blocks 317 are arranged at intervals on the peripheral wall of the rotating shaft 316. The driving block 317 is used to abut the side wall of the abutment block 3262 toward the separation box 321, and the abutment interval time between two adjacent driving blocks 317 and the abutment block 3262 is the same as the time when two adjacent bucket boxes 314 pass through the receiving hopper 325.

[0063] In this embodiment, the transmission rod 3261 and the abutment block 3262 are integrally arranged, and the abutment block 3262 is located at one end of the transmission rod 3261 away from the separation box 321 and abuts against the driving block 317. The rotating shaft 316 is located outside the lifting box 311, and there are three driving blocks 317, each of which slides and abuts against the abutment block 3262 in turn.

[0064] It should be noted that if Figure 3 and Figure 4 As shown, when the sprocket 312 drives the bucket box 314 to rotate downward, the rotating shaft 316 drives the driving block 317 to rotate clockwise, so that when the driving block 317 just contacts the abutting block 3262, the end of the receiving bucket 325 away from the first spring 3251 is simultaneously located at the discharge port 3111 and the feed port 3211, and the first spring 3251 is in a stretched state. Until the driving block 317 abuts against the abutting block 3262 and is about to slide over the abutting block 3262, during this process, the driving block 317 abuts against the abutting block 3262 to drive the transmission rod 3261 to slide toward the lifting box 311, thereby driving the receiving bucket 325 to slide between the two adjacent bucket boxes 314 of the lifting box 311, so that the receiving bucket 325 can receive more pills dumped from the bucket box 314 at the upper end of the sprocket 312. Until the driving block 317 slides over the abutment block 3262, the receiving hopper 325 is driven to slide out from between adjacent hopper boxes 314 and enter the separation box 321 under the pulling force of the first spring 3251, so that the hopper 314 on the sprocket 312 can rotate downward smoothly; and when the next hopper box 314 reaches the upper end of the sprocket 312, the next driving block 317 abuts against the abutment block 3262 again, so that the receiving hopper 325 slides between the adjacent hopper boxes 314 again, and so on, so that each time the receiving hopper 325 slides, it can slide between the adjacent hopper boxes 314 to receive more pill materials.

[0065] It is worth noting that a rotating column 3263 is provided on the transmission rod 3261. The rotating column 3263 slides through the side wall of the separation box 321 and is rotatably connected to the receiving hopper 325. A through hole is provided on the side wall of the separation box 321 for the rotating column 3263 to slide in the horizontal direction. A torsion spring is also sleeved on the rotating column 3263, and the torsion spring acts on the receiving hopper 325 to keep the receiving hopper 325 sliding in the horizontal direction. The transmission member 326 also includes a limiting cylinder 3264. The limiting cylinder 3264 is fixed to both sides of the separation box 321 and covers the through hole on the separation box 321 for connecting the transmission rod 3261 and the receiving hopper 325, and the transmission rod 3261 is slidably penetrated in the limiting cylinder 3264 to limit the sliding of the transmission rod 3261. When the torsion spring is in the natural state, the receiving hopper 325 slides in the separation box 321 in the horizontal direction. Under the action of the torsion spring, even if the rotating bucket box 314 presses down the receiving bucket 325, the receiving bucket 325 can still recover after rotating to provide space for the bucket box 314 to rotate, so that the sliding of the receiving bucket 325 can be fault-tolerant, the smoothness of the clockwise rotation of the bucket box 314 is improved, and the feasibility of the receiving bucket 325 is increased.

[0066] In some embodiments, the bottom wall of the receiving hopper 325 has a tooth pattern 3252. One end of the guide plate 322 close to the receiving hopper 325 slides against the tooth pattern 3252 of the receiving hopper 325, and the guide plate 322 is elastic. The guide plate 322 is rotatably arranged in the separation box 321, and a torsion spring is also arranged at the rotation connection between the guide plate 322 and the separation box 321. In the natural state of the torsion spring of the guide plate 322, one end of the guide plate 322 close to the receiving hopper 325 slides against the tooth pattern 3252, so that the sliding of the receiving hopper 325 and the sliding contact between the tooth pattern 3252 and the guide plate 322 drive the guide plate 322 to vibrate at a faster frequency, which helps to reduce the splash range of the pills on the guide plate 322.

[0067] Exemplarily, the guide plate 322 includes a first plate 3221 that is slidably abutted against the receiving hopper 325, and a second plate 3222 that is connected to the end of the first plate 3221 away from the receiving hopper 325. The first plate 3221 and the second plate 3222 form an obtuse angle, and the height of the end of the second plate 3222 away from the first plate 3221 is flush with the top wall of the connecting opening 3231 on the partition plate 323. The first plate 3221 and the second plate 3222 are integrally arranged, and the length of the first plate 3221 is equal to the length of the second plate 3222. The obtuse angle between the first plate 3221 and the second plate 3222 ranges from 120° to 135°, and the obtuse angle openings of the first plate 3221 and the second plate 3222 face the upper partition plate 3232, so that the pellets can be smoothly shaken into the coarse material chamber 3212 below by shaking the first plate 3221 and the second plate 3222.

[0068] In some embodiments, a dust cover 3242 is sleeved on the side wall of the fan 324 located in the separation box 321. The dust cover 3242 is provided with a plurality of through holes. The dust cover 3242 is slidably sleeved on the fan 324, and a plurality of second springs 3243 are provided on the dust cover 3242. One end of the second spring 3243 away from the dust cover 3242 is provided on the fan 324. An abutment rod 3215 is slidably provided on the inner wall of the separation box 321. One end of the abutment rod 3215 abuts against one end of the second material plate 3222 away from the first material plate 3221, and the other end of the abutment rod 3215 abuts against the dust cover 3242.

[0069] In this embodiment, there are two abutment rods 3215, which slide on two opposite inner walls of the separation box 321 respectively. The abutment rods 3215 are L-shaped, so that the abutment rods 3215 attached to the inner wall of the separation box 321 can be bent and abut the dust cover 3242. The inner wall of the separation box 321 is provided with a sliding groove for the abutment rods 3215 to slide, so as to limit the horizontal sliding of the abutment rods 3215, and the two abutment rods 3215 are respectively abutted against the lower end of the second material plate 3222, so that the abutment rods 3215 are continuously abutted against the dust cover 3242 through the shaking of the second material plate 3222, so as to realize the bouncing of the dust cover 3242, and the smoke accumulated on the dust cover 3242 is shaken off into the fine material chamber 3213.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
