Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure pump processing, and in particular to a positioning mechanism used for the production and processing of high-pressure pumps. Background Art

[0002] High-pressure pumps are equipment that provide high-pressure power for high-pressure rotary jet cement slurry. They are used for strengthening the foundations of buildings, roads, etc. They can also be used for high-pressure water jets to assist in breaking rocks and dropping coal, supplying fluid to underground hydraulic props, pumping high-pressure water for anchored hydraulic expansion metal anchors, and clearing, dredging, and cleaning large underground pipelines.

[0003] To meet installation requirements, the high-pressure pump housing has an irregular shape. Therefore, when the high-pressure pump housing is milled, stamped, or subjected to other operations, it needs to be clamped and fixed by a positioning fixture to ensure stable processing of the high-pressure pump housing. For example, Chinese patent CN117066934B discloses a positioning fixture for hydraulic pump processing. The positioning fixture is provided with a dust collection and purification mechanism, which can be rotated and adjusted around the processing position of the workpiece to absorb dust and debris, reduce the problem of dust collection dead angles, and ensure the effect of dust collection and purification. However, during the processing of the hydraulic pump housing clamped by the positioning fixture, debris will splash everywhere. At the same time, the dust collection and purification mechanism is easily stuck by debris when rotating around the workpiece, and the debris adsorption effect is poor. Therefore, we propose a positioning mechanism for the production and processing of high-pressure pumps. Summary of the Invention

[0004] The purpose of the present invention is to provide a positioning mechanism for the production and processing of high-pressure pumps, which has the effect of automatically loading and unloading the high-pressure pump housing to realize continuous processing of the high-pressure pump housing while preventing debris from splashing and adsorbing and cleaning the debris.

[0005] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: a positioning mechanism for the production and processing of a high-pressure pump, comprising a base, a column mounted on the base, a rotating disk rotatably connected to the outside of the column, a driving component mounted on the base to drive the rotating disk to rotate, and four clamping components distributed in an annular shape and equidistant manner and mounted on the rotating disk, the rotating disk is provided with a control component for controlling the opening or closing of a single clamping component, a dust cover located on the outside of the rotating disk is also installed on the base, the height of the dust cover is higher than the height of the clamping component, a connecting ring with one end that is in contact with the outer side of the rotating disk is installed on the dust cover, a retaining ring is installed on the rotating disk, an inner baffle corresponding to the clamping component is installed on the rotating disk, an adsorption component is installed on the column, the air outlet of the adsorption component is located on the side of the inner baffle away from the clamping component, the air inlet of the adsorption component is located on the dust cover, and a sealing component with one end that is in contact with the upper surface of the inner baffle is also installed on the dust cover.

[0006] By adopting the above technical solution, the high-pressure pump housing is fixed on the clamping assembly for processing, the driving assembly is started to drive the four clamping assemblies on the rotating disk to rotate, and the control assembly controls two of the clamping assemblies to open, one for removing the processed high-pressure pump housing, and the other for assembling a new high-pressure pump housing for processing. One of the remaining two clamping assemblies is rotated to the bottom of the processing equipment for processing, and the other is covered by the sealing assembly, and the debris on its surface is adsorbed by the adsorption assembly. This reciprocating process automatically loads and unloads the high-pressure pump housing to achieve continuous processing of the high-pressure pump housing. At the same time, the debris generated during the processing on multiple clamping assemblies can be adsorbed one by one, and the cleaning effect is better.

[0007] During the processing, the dust cover can block the splashing of debris from the outside, while the inner baffle blocks the debris from the inside and blocks the air outlet of the adsorption component. When multiple clamping components are rotated one by one to the air inlet of the adsorption component, the debris generated by the processing on multiple clamping components can be adsorbed. During the adsorption process, the sealing component is used to start the inner baffle at the corresponding position to cover the clamping component at the corresponding position, reducing the possibility of debris flying everywhere during the blowing and adsorption process, and avoiding pollution of the working environment.

[0008] In order to allow the air outlet end of the adsorption component to blow air outward from the center point and the air inlet end to cooperate with suction from the other side to improve the debris collection effect, the driving component is set at the eccentric point of the rotating disk. When the driving component is started and the rotating disk drives the high-pressure pump housing on the clamping component to rotate, the connecting ring is used to fit with the outer side of the rotating disk to improve the rotation stability of the rotating disk. The retaining ring blocks the connection between the connecting ring and the rotating disk to prevent debris generated during the processing from getting stuck at the connection between the connecting ring and the rotating disk and affecting the rotation of the rotating disk. At the same time, it can prevent debris from falling under the rotating disk and affecting the normal operation of the control component and the driving component.

[0009] The present invention is further configured as follows: the driving assembly includes a driving motor mounted on the base, a driving gear fixedly connected to the output shaft of the driving motor, and a gear ring mounted on the bottom of the rotating disk, and the driving gear is meshed with the gear ring.

[0010] By adopting the above technical solution, the driving motor is started to drive the active gear to rotate, and the active gear engages with the gear ring to push the rotating disk to rotate outside the column, driving the multiple clamping components to rotate, thereby realizing continuous processing of the high-pressure pump housing and adsorbing the debris generated during the processing on the multiple clamping components one by one.

[0011] The present invention is further configured as follows: the clamping assembly includes a fixed ring installed on the rotating disk, a clamping disk installed on the inner side of the fixed ring, a plurality of equally spaced vertical plates fixedly installed on the clamping disk, a plurality of equally spaced clamping plates slidably connected to the clamping disk, and a connecting spring connecting the vertical plates and the clamping plates, and a connecting column located below the clamping disk is installed at the bottom of the clamping plate, and the side surface of the connecting column is an inclined surface.

[0012] The present invention is further configured as follows: the control assembly includes a rotating rod rotatably connected to the rotating disk, a rotating ring installed on the outside of the rotating rod, a plurality of equally spaced arc-shaped protrusions installed on the rotating ring, a guide column installed at the bottom of two symmetrically distributed arc-shaped protrusions, an arc-shaped groove opened on the rotating disk, a return spring installed in the arc-shaped groove, a rotating gear installed on the outside of the rotating rod and located below the rotating disk, and two arc-shaped racks installed on the dust cover, the bottom of the guide column slides in the arc-shaped groove and is fixedly connected to the return spring.

[0013] When the gears on the plurality of rotating rods are engaged with the second segment of the arc rack in turn, the new high-pressure pump housing can be assembled, and the high-pressure pump housing can be automatically loaded and unloaded to realize continuous processing of the high-pressure pump housing, thereby improving the processing efficiency of the high-pressure pump housing.

[0014] The present invention is further configured as follows: the side of the retaining ring close to the dust cover is tilted downward, the bottom of the retaining ring is provided with bristles that fit the surface of the connecting ring, and the connecting ring is provided with a receiving groove.

[0015] By adopting the above technical solution, the inclined retaining ring facilitates the introduction of blocked debris onto the connecting ring, and then when the retaining ring rotates with the rotating disk, the bristles can clean the surface of the connecting ring and introduce the debris into the receiving groove for collection, thereby realizing the collection and cleaning of debris.

[0016] The present invention is further configured as follows: the adsorption component includes a fan installed inside the column, an air outlet pipe connected to the air outlet end of the fan, an air outlet nozzle connected to the other side of the air outlet pipe, a dust collection box connected to the air inlet end of the fan, an air intake pipe connected to the other side of the dust collection box and extending into the dust cover, and two air intake nozzles connected to the air intake pipe.

[0017] By adopting the above technical solution, the fan is started, and its air outlet end blows the debris from the middle to the outside through the air outlet nozzle, and its air inlet end absorbs the blown debris on the outside through the air suction nozzle. The debris absorption effect is better and as the rotating disk drives the clamping assembly to rotate, the debris on each clamping assembly can be absorbed one by one. In the process of cleaning the debris, the sealing assembly is started to cooperate with the inner baffle at the corresponding position to cover the clamping assembly at the corresponding position, thereby reducing the possibility of debris flying everywhere during the blowing and absorption process, and avoiding pollution of the working environment.

[0018] The present invention is further configured as follows: one of the air suction nozzles is arranged at a height on the dust cover that is not lower than the height of the clamping disk, the other air suction nozzle is connected to the storage groove, the air outlet nozzle is fixed on the rotating disk through a bracket, and an air outlet mesh hole is provided on the inner baffle for the air outlet nozzle to blow air.

[0019] By adopting the above technical solution, one suction nozzle is used to absorb the debris generated during the processing on the clamping disk, and the other suction nozzle is used to absorb the debris collected in the storage tank. No manpower is required for cleaning, which is more convenient to use.

[0020] The present invention is further configured as follows: the air outlet mesh hole is a tapered hole, and the hole diameter on the side close to the air outlet nozzle is larger than the hole diameter on the side away from the air outlet nozzle.

[0021] By adopting the above technical solution, it is ensured that the wind can be blown out from the middle while debris will not enter the air outlet nozzle through the air outlet mesh, and the wind blown out by the fan is blown from the end with a larger aperture to the end with a smaller aperture, which is more conducive to the concentration of wind force.

[0022] The present invention is further configured as follows: the sealing assembly includes a top plate installed on the dust cover, two sealing plates slidably connected to the top plate, a connecting frame connecting the two sealing plates, and a cylinder installed on the top plate, and the output end of the cylinder is fixedly connected to the sealing plate.

[0023] By adopting the above technical solution, when any clamping component rotates to the bottom of the top plate with the rotating disk, the top plate fits with the inner baffle at the corresponding position to block the left and right sides of the clamping disk, and then the cylinder is started to push the connecting frame up and down, thereby driving the two sealing plates to slide up and down on the top plate. The sealing plate slides downward to cover the front and back sides of the clamping disk, reducing the possibility of debris flying everywhere during the blowing and adsorption process, avoiding pollution of the working environment, and the sealing plate slides upward to open the inlet and outlet channels of the clamping component, so that multiple clamping components can be sealed one by one, realizing continuous debris cleaning work of the clamping components.

[0024] The present invention is further configured as follows: the distance between the two sealing plates is greater than the diameter of the clamping disk, and anti-slip rings are installed at the bottoms of the two sealing plates.

[0025] By adopting the above technical solution, the entire clamping disc can be covered to clean the debris on its surface, and the anti-slip ring is set to prevent the sealing plate from separating from the top plate during the movement.

[0026] The present invention is further configured such that the two sections of the arc-shaped rack are separated by a top plate.

[0027] By adopting the above technical solution: when the rotating gears on multiple rotating rods engage with the first arc-shaped rack in turn to take out the processed high-pressure pump housing, they are first rotated to the bottom of the top plate to adsorb the debris on the clamping plate, and then rotated to engage with the second arc-shaped rack to assemble a new high-pressure pump housing for processing, which is conducive to achieving continuous work of high-pressure pump housing processing, disassembly, cleaning and assembly, and improving processing efficiency.

[0028] The present invention is further configured as follows: the column is a hollow column, the dust box is slidably connected to the column, and the base is provided with a strip hole for taking out or putting in the dust box.

[0029] By adopting the above technical solution, after the dust box collects the debris, it can be taken out for cleaning.

[0030] The beneficial effects of the present invention are:

[0031] 1. The high-pressure pump casing is fixed on the clamping assembly for processing. The driving assembly starts to drive the four clamping assemblies on the rotating disk to rotate. The control assembly controls two of the clamping assemblies to open, one for removing the processed high-pressure pump casing, and the other for assembling a new high-pressure pump casing for processing. One of the remaining two clamping assemblies is rotated to the bottom of the processing equipment for processing, and the other is covered by the sealing assembly. The adsorption assembly adsorbs the debris on its surface. This reciprocating process automatically loads and unloads the high-pressure pump casing to achieve continuous processing of the high-pressure pump casing. At the same time, the debris generated during the processing on multiple clamping assemblies can be adsorbed one by one, and the cleaning effect is better.

[0032] 2. During the processing, the dust cover can block the splash of debris from the outside, while the inner baffle blocks the debris from the inside and blocks the air outlet of the adsorption component. When multiple clamping components rotate one by one to the air inlet of the adsorption component, the debris generated by the processing on multiple clamping components can be adsorbed. During the adsorption process, the sealing component is used to start and cooperate with the inner baffle at the corresponding position to cover the clamping component at the corresponding position, reducing the possibility of debris flying around during the blowing and adsorption process, and avoiding pollution of the working environment.

[0033] 3. In order to allow the air outlet of the adsorption component to blow air outward from the center point and the air inlet end to cooperate with suction from the other side to improve the debris collection effect, the drive component is set at the eccentric point of the rotating disk. When the drive component is started and the rotating disk drives the high-pressure pump housing on the clamping component to rotate, the connecting ring is used to fit with the outer side of the rotating disk to improve the stability of the rotation of the rotating disk. The retaining ring blocks the connection between the connecting ring and the rotating disk to prevent debris generated during the processing from getting stuck at the connection between the connecting ring and the rotating disk and affecting the rotation of the rotating disk. At the same time, it can prevent debris from falling under the rotating disk and affecting the normal operation of the control component and the drive component.

[0034] 4. When the retaining ring rotates with the rotating disk, the bristles can clean the surface of the connecting ring and guide the debris into the receiving groove for collection, thereby realizing the collection and cleaning of the debris. An air suction nozzle of the adsorption component is connected to the receiving groove. While adsorbing the clamping component, it can also adsorb the debris collected in the receiving groove. No manpower is required for cleaning, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0045] See also Figure 1-7 The present invention provides a positioning mechanism for the production and processing of high-pressure pumps, comprising a base 1, a column 2 mounted on the base 1, a rotating disk 4 rotatably connected to the outside of the column 2, a driving component mounted on the base 1 for driving the rotating disk 4 to rotate, and four clamping components equidistantly distributed in an annular shape and mounted on the rotating disk 4. The rotating disk 4 is provided with a control component for controlling the opening or closing of a single clamping component 8. The base 1 is also provided with a dust cover 3 located on the outside of the rotating disk 4. The height of the dust cover 3 is higher than the height of the clamping component. The dust cover 3 is provided with a connecting ring 22 with one end abutting the outer side of the rotating disk 4. The rotating disk 4 is provided with a retaining ring 23. The rotating disk 4 is also provided with an inner baffle 26 corresponding to the clamping component. The column 2 is provided with an adsorption component. The air outlet of the adsorption component is located on the side of the inner baffle 26 away from the clamping component. The air inlet of the adsorption component is located on the dust cover 3. The dust cover 3 is also provided with a closing group with one end abutting the upper surface of the inner baffle 26.

[0046] The high-pressure pump housing is fixed on the clamping assembly for processing. The driving assembly is started to drive the four clamping assemblies on the rotating disk 4 to rotate. The control assembly controls two of the clamping assemblies to open, one for taking out the processed high-pressure pump housing, and the other for assembling a new high-pressure pump housing for processing. One of the remaining two clamping assemblies is rotated to the bottom of the processing equipment for processing, and the other is covered by the sealing assembly. The adsorption assembly adsorbs the debris on its surface. This reciprocating process automatically loads and unloads the high-pressure pump housing to achieve continuous processing of the high-pressure pump housing. At the same time, the debris generated during the processing on multiple clamping assemblies can be adsorbed one by one, and the cleaning effect is better.

[0047] During the processing, the dust cover 3 can block the splashing of debris from the outside, while the inner baffle 26 blocks the debris from the inside and blocks the air outlet of the adsorption component. When multiple clamping components are rotated one by one to the air inlet of the adsorption component, the debris generated by the processing on multiple clamping components can be adsorbed. During the adsorption process, the sealing component is used to start and cooperate with the inner baffle 26 at the corresponding position to cover the clamping component at the corresponding position, thereby reducing the possibility of debris flying everywhere during the blowing and adsorption process, and avoiding pollution of the working environment.

[0048] In order to allow the air outlet end of the adsorption component to blow air outward from the center point and the air inlet end to cooperate with suction from the other side to improve the debris collection effect, the driving component is set at the eccentric point of the rotating disk 4. When the driving component is started, the rotating disk 4 drives the high-pressure pump housing on the clamping component to rotate. The connecting ring 22 is used to fit with the outer side of the rotating disk 4 to improve the rotation stability of the rotating disk 4. The retaining ring 23 blocks the connection between the connecting ring 22 and the rotating disk 4 to prevent debris generated during the processing from being stuck at the connection between the connecting ring 22 and the rotating disk 4 and affecting the rotation of the rotating disk 4. At the same time, it can prevent debris from falling under the rotating disk 4 and affecting the normal operation of the control component and the driving component.

[0049] The driving assembly includes a driving motor 5 installed on the base 1, a driving gear 6 fixedly connected to the output shaft of the driving motor 5, and a gear ring 7 installed at the bottom of the rotating disk 4. The driving gear 6 is engaged with the gear ring 7. When the driving motor 5 is started, the driving gear 6 is driven to rotate. The driving gear 6 is engaged with the gear ring 7 to push the rotating disk 4 to rotate outside the column 2, driving the multiple clamping assemblies to rotate, thereby realizing continuous processing of the high-pressure pump housing and adsorbing the debris generated during the processing on the multiple clamping assemblies one by one.

[0050] The clamping assembly 8 includes a fixing ring 8 mounted on the rotating disk 4, a clamping disk 9 mounted on the inner side of the fixing ring 8, a plurality of equally spaced vertical plates 10 fixedly mounted on the clamping disk 9, a plurality of equally spaced clamping plates 11 slidably connected to the clamping disk 9, and a connecting spring 12 connecting the vertical plates 10 and the clamping plates 11. A connecting column 13 located below the clamping disk 9 is installed at the bottom of the clamping plate 11, and the side of the connecting column 13 is an inclined surface. The control assembly includes a rotating rod 14 rotatably connected to the rotating disk 4, a plurality of equally spaced vertical plates 10 fixedly mounted on the clamping disk 9, and a plurality of equally spaced clamping plates 11 slidably connected to the clamping disk 9, and a connecting spring 12 connecting the vertical plates 10 and the clamping plates 11. The rotating ring 15 on the outside of the rotating rod 14, a plurality of equally spaced arc-shaped protrusions 16 mounted on the rotating ring 15, a guide column 17 mounted at the bottom of two symmetrically distributed arc-shaped protrusions 16, an arc-shaped groove 18 provided on the rotating disk 4, a return spring 19 mounted in the arc-shaped groove 18, a rotating gear 20 mounted on the outside of the rotating rod 14 and located below the rotating disk 4, and two arc-shaped racks 21 mounted on the dust cover 3, the bottom of the guide column 17 slides in the arc-shaped groove 18 and is fixed with the return spring 19 The rotating rod 14 is fixedly connected, and when the rotating disk 4 rotates, the rotating gear 20 on the multiple rotating rods 14 engages with the first arc-shaped rack 21 in turn, so that the rotating rod 14 at the corresponding position rotates, and then the arc-shaped protrusion 16 on the rotating ring 15 rotates to squeeze the connecting column 13, driving the guide column 17 at the corresponding position to slide in the arc groove 18 to squeeze the return spring 19. At the same time, the splint 11 moves close to the vertical plate 10 to squeeze the connecting spring 12, increasing the distance between the multiple splints 11, and the processed high-pressure pump housing can be taken out. When the rotating gear 20 on the rotating rod 14 is engaged with the first arc-shaped rack 21, the rotating rod 14 at the corresponding position rotates, and then the arc-shaped protrusion 16 on the rotating ring 15 rotates to squeeze the connecting column 13, driving the guide column 17 at the corresponding position to slide in the arc groove 18 to squeeze the return spring 19. At the same time, the splint 11 moves close to the vertical plate 10 to squeeze the connecting spring 12, increasing the distance between the multiple splints 11, and the processed high-pressure pump housing can be taken out. When the moving gear 20 is separated from the first arc-shaped rack 21, the return spring 19 is reset to make the guide column 17 push the rotating ring 15 to rotate in the opposite direction, and the arc-shaped protrusion 16 no longer squeezes the connecting column 13. The connecting spring 12 is reset to push the clamping plate 11 away from the vertical plate 10 to clamp the high-pressure pump housing. When the rotating gears 20 on multiple rotating rods 14 are engaged with the second arc-shaped rack 21 in turn, the new high-pressure pump housing can be assembled. The high-pressure pump housing can be automatically loaded and unloaded to realize continuous processing of the high-pressure pump housing, thereby improving the processing efficiency of the high-pressure pump housing.

[0051] The side of the retaining ring 23 close to the dust cover 3 is tilted downward, and the bottom of the retaining ring 23 is equipped with bristles 24 that fit the surface of the connecting ring 22. A receiving groove 25 is provided on the connecting ring 22. The inclined retaining ring 23 facilitates the introduction of blocked debris into the connecting ring 22, and then when the retaining ring 23 rotates with the rotating disk 4, the bristles 24 can clean the surface of the connecting ring 22 and introduce the debris into the receiving groove 25 for collection, thereby realizing the collection and cleaning of debris.

[0052] The suction assembly includes a fan 27 installed inside the column 2, an air outlet pipe 28 connected to the air outlet end of the fan 27, an air outlet nozzle 36 connected to the other side of the air outlet pipe 28, a dust collection box 29 connected to the air inlet end of the fan 27, an air suction pipe 30 connected to the other side of the dust collection box 29 and extending into the dust cover 3, and two air suction nozzles 31 connected to the air suction pipe 30. When the fan 27 is started, the air outlet end thereof blows the debris from the middle to the outside through the air outlet nozzle 36, and the air inlet end thereof absorbs the blown debris on the outside through the air suction nozzle 31. The debris adsorption effect is better and as the rotating disk 4 drives the clamping assembly to rotate, the debris on each clamping assembly can be adsorbed one by one. In the process of cleaning the debris, the sealing assembly is started to cooperate with the inner baffle 26 at the corresponding position to cover the clamping assembly at the corresponding position, thereby reducing the possibility of debris flying around during the blowing and adsorption process and avoiding pollution of the working environment.

[0053] The height of one of the suction nozzles 31 set on the dust cover 3 is not lower than the height of the clamping disk 9, and the other suction nozzle 31 is connected to the receiving groove 25. The air outlet nozzle 36 is fixed to the rotating disk 4 through a bracket. The inner baffle 26 is provided with an air outlet mesh for the air outlet nozzle 36 to blow air. One suction nozzle 31 is used to absorb debris generated during the processing on the clamping disk 9, and the other suction nozzle 31 is used to absorb debris collected in the receiving groove 25. No manpower is required to clean it, which is more convenient to use. The air outlet mesh is a conical hole, and the aperture on the side close to the air outlet nozzle 36 is larger than the aperture on the side away from the air outlet nozzle 36, ensuring that the wind can be blown out from the middle while the debris will not enter the air outlet nozzle 36 through the air outlet mesh, and the wind blown out by the fan 27 blows from the end with a larger aperture to the end with a smaller aperture, which is more conducive to the concentration of wind force.

[0054] When any clamping assembly rotates to the bottom of the top plate 32 with the rotating disk 4, the top plate 32 fits with the inner baffle 26 at the corresponding position, blocking the left and right sides of the clamping disk 9. Then the cylinder 35 starts to push the connecting frame 34 up and down, thereby driving the two sealing plates 33 to slide up and down on the top plate 32. The sealing plates 33 slide downward to cover the front and back sides of the clamping disk 9, reducing the possibility of debris flying everywhere during the blowing and adsorption process and avoiding pollution of the working environment. The sealing plates 33 slide upward to open the inlet and outlet channels of the clamping assembly, so that multiple clamping assemblies can be sealed one by one, thereby realizing continuous debris cleaning of the clamping assembly.

[0055] The distance between the two sealing plates 33 is greater than the diameter of the clamping disk 9. Anti-slip rings are installed at the bottom of the two sealing plates 33, which can cover the entire clamping disk 9 to clean the debris on its surface. The setting of the anti-slip ring prevents the sealing plate 33 from separating from the top plate 32 during movement.

[0056] The two sections of the arc-shaped rack 21 are separated by the top plate 32. When the rotating gears 20 on the multiple rotating rods 14 are engaged with the first section of the arc-shaped rack 21 in turn, when taking out the processed high-pressure pump housing, they are first rotated to the bottom of the top plate 32 to adsorb the debris on the clamping plate 9, and then rotated to engage with the second section of the arc-shaped rack 21 to assemble a new high-pressure pump housing for processing. This is conducive to achieving the continuous work of processing, disassembly, cleaning and assembly of the high-pressure pump housing, thereby improving processing efficiency.

[0057] The column 2 is a hollow column, and the dust box 29 is slidably connected to the column 2. The base 1 is provided with a strip hole for taking out or putting in the dust box 29. After the dust box 29 collects the debris, it can be taken out for cleaning.
