Description

Technical Field

[0001] The invention relates to the technical field of wall trenching, and in particular to a wall trenching device with a cleaning function. Background Art

[0002] In the prior art, when a wall needs to be wired or a water pipe is laid, a trench needs to be opened on its surface. The main method of opening the trench is to drill the wall with a rotating saw blade to open the trench. After the trench is opened, there will be some raised particles on the inner surface of the opened trench, which will affect the flatness of the inner wall of the trench, making it inconvenient to lay the water and electricity pipelines later. Therefore, the present application proposes a wall trenching device with a cleaning function, which is convenient for processing the raised particles on the inner surface of the trench after the trench is opened, so as to ensure the overall flatness of the inner surface of the trench.

[0003] After searching, the Chinese patent application number 202122988532.9 discloses an intelligent wall groove garbage cleaning device, including an electric drill body, to which a detachable transparent cover is fixedly connected, and the transparent cover can rotate around the outside of the electric drill body, and the side wall of the transparent cover is fixedly connected with a cowhide cover, and the side wall of the cowhide cover is fixedly connected with a support ring, and the side wall of the transparent cover is slidably connected with two sliding rods passing through the transparent cover, and the ends of the two sliding rods are fixedly connected to the support ring, and a reset spring is provided on the outside of the two sliding rods near the support ring and the transparent cover.

[0004] The intelligent cleaning device for wall groove garbage in the above patent has the following shortcomings: during the hammering of concrete bumps, the hammer cone can only clean the concrete bumps in a smaller area.

[0030] 1. By setting the straight-line distance between the two rollers to be adjustable, and then utilizing the movement of the guide hole on the surface of the guide plate relative to the toggle column, the grooving depth of the grooving saw blade can be adjusted within a certain range. The rolling of the rollers during the grooving process is utilized to drive the conical scraper to slide back and forth along the inner wall of the groove, and the conical scraper is utilized to scrape off the raised particles on the inner wall of the groove to ensure the flatness of the groove.

[0034] 5. The two groups of cross wheels are cross-stacked. When it is necessary to collect the particles scraped off by the conical scraper, the elastic force of the second spring is used to keep the outer walls of the two groups of cross wheels and the side walls of the grooves in close contact, thereby reducing the gap between the grooves and avoiding the overflow of particles. The pushing action of the push plate is used to make the trigger plate drive the corresponding absorption tube and the cross wheel to slide relative to the other cross wheel. When particles with larger particle sizes are stuck in the gap between the two cross wheels, the relative movement between the two cross wheels is used to remove the particles by pushing.

[0050] Frame 13: It is fixed to the output end of the electric telescopic rod 10 by a pin, and the inner wall of the through hole opened on the surface of the L-shaped plate 11 is rotatably connected to a rotating column 23, and one end of the rotating column 23 is fixed to a clamping seat 24 by a pin;

[0051] Rollers 53: Two rollers 53 are respectively fixed to one end of the rotating column 23 by pins and are rotatably connected to the inner wall of the through hole opened on the surface of 11;

[0052] Slideway 39: welded to the outer wall of one side of the connecting frame 18;

[0053] The swing arm 5 is rotatably connected to the outer wall of one side of the roller 53, and one end of the swing arm 5 away from the roller 53 is rotatably connected to the lining rod 7, and one end of the lining rod 7 is fixed with the accommodating plate 26 by a pin;

[0054] T-shaped rod 27: it is slidably connected to the inner wall of the through hole opened on the surface of the accommodating plate 26, and one end of the T-shaped rod 27 is fixed with a guide seat 29 through a pin, and the guide seat 29 and the notch plate 28 are fixedly connected;

[0055] The threaded column 30 is connected to the inner wall of the threaded hole formed on the surface of the guide seat 29 through a thread, and one end of the threaded column 30 is rotatably connected to a conical scraper 31;

[0056] Correction rod 54: It is fixed to the outer wall of one side of the conical scraper 31 by a pin, and a through hole matching the outer diameter of the correction rod 54 is opened on the surface of the guide seat 29;

[0057] Sliding block 6: It is slidably connected to the outer wall of the liner rod 7, and a guide plate 25 is welded to the outer wall of one side of the sliding block 6, and a guide hole 22 is opened on the surface of the guide plate 25;

[0058] Transverse sliding rod 35: It is slidably connected to the inner wall of the through hole opened on the surface of the connecting frame 18, and one end of the transverse sliding rod 35 is fixed with a trenching frame 36 through a pin, and the trenching part is installed on the surface of the trenching frame 36;

[0059] Vertical plate 33: It is welded to the outer wall of one side of the trenching frame 36, and a connecting piece 37 is welded on the surface of the vertical plate 33, and a toggle column 38 is rotatably connected to the surface of the connecting piece 37, and the outer diameter of the toggle column 38 and the inner diameter of the guide hole 22 are adapted to each other;

[0060] A trenching part is provided to perform trenching operation on the wall surface. When trenching is required, the roller 53 is fitted to the wall surface, and the roller 53 is used for supporting. The electric telescopic rod 10 is used to drive the L-shaped plate 11 and the roller 53 to perform linear motion. When the roller 53 is performing linear motion, the guide plate 25 is relatively displaced relative to the toggle column 38. A guide hole 22 is provided on the surface of the guide plate 25 to guide the moving path of the toggle column 38. The guide hole 22 is composed of a straight hole and an inclined hole. When the inclined hole area moves and contacts the toggle column 38, the inclined hole converts the lateral linear motion of the guide plate 25 into the longitudinal linear motion of the trenching frame 36. When the trenching part is started to trench the wall, the trenching depth is adjusted within a certain range by adjusting the longitudinal moving distance of the trenching frame 36.

[0061] During the trenching process, the roller 53 is driven to roll along the wall surface. During the rolling process, the roller 53 uses the swing arm 5 to convert the circular motion of the roller 53 into the linear motion of the lining rod 7. During the movement of the lining rod 7, the conical scraper 31 is driven to reciprocate along the inner wall of the groove. By rotating the threaded column 30, the conical scraper 31 is guided by the correction rod 54 to make a linear motion, thereby adjusting the depth of the conical scraper 31 into the groove. When the conical scraper 31 contacts the bottom of the groove, the conical scraper 31 is used to remove a small amount of incomplete residual material at the bottom of the groove during the rolling process of the roller 53. The completely removed particles are scraped to ensure the flatness of the bottom of the groove. In this embodiment, the conical scraper 31 is a fence structure, that is, a certain number of grooves are opened on the surface of the conical scraper 31. The grooves are provided to facilitate the falling of the scraped particles and avoid the accumulation of particles on the surface of the conical scraper 31. By setting the conical scraper 31 as a trapezoidal structure, the falling rate of the particles is accelerated. In this embodiment, the number of fence structures on the conical scraper 31 is preferably two groups, and the gaps between the two fence structures are staggered with each other, so that the two fence structures cooperate with each other to avoid the existence of cleaning dead corners in the gaps, which affects the cleaning effect.

[0062] Further, the trenching part includes a trenching saw blade 52 and a clamping head 34, the trenching saw blade 52 is rotatably connected to the inner wall of the through hole opened on both sides of the trenching frame 36, the clamping head 34 is fixed to one end of the conical scraper 31 by a pin, and the trenching part also includes a trenching motor 14 and a pulley 32, the trenching motor 14 is fixed to the outer wall of one side of the trenching frame 36 by bolts, and the two pulleys 32 are respectively fixed to the output end of the trenching motor 14 and the outer wall of the circumference of the trenching saw blade 52 by pins, and the two pulleys 32 are driven by a belt;

[0063] The ditching motor 14 drives the ditching saw blade 52 to rotate by the transmission effect of the belt and the pulley 32. The ditching saw blade 52 performs ditching on the wall surface during the rotation. When the particles in a certain area of ​​the groove are difficult to clean, the electric telescopic rod 10 is used to drive the clamping seat 24 to move linearly, so that the clamping seat 24 and the clamping head 34 are engaged. At this time, the clamping head 34 and the clamping seat 24 are as a whole. By adjusting the positions of the ditching saw blade 52 and the roller 53, the ditching saw blade 52 is temporarily separated from the groove, and the roller 53 is temporarily separated from the wall. When the ditching motor 14 drives the clamping head 34 to rotate, the clamping seat 24 and the roller 53 are synchronously driven to rotate. During the rotation of the roller 53, the swing arm 5 is used to drive the conical scraper 31 to reciprocate along the inner wall of the groove for a long time, so as to reciprocate and clean the particles in the groove that are difficult to clean, thereby ensuring the cleaning effect.

[0064] At the same time, by setting a straight hole on the guide hole 22, when the toggle column 38 moves along the straight hole, the positions of the ditching frame 36 and the clamping seat 24 will not change, ensuring that the clamping seat 24 can be smoothly docked with the clamping head 34 during the movement, avoiding misalignment between the two and resulting in failure to connect.

[0065] Further, a lead screw guide rail 3 is fixed to the top outer wall of the base 1 by bolts, a cushion block 16 is slidably connected to the output end of the lead screw guide rail 3, and a rotating motor 15 is fixed to the inner wall of one side of the cushion block 16 by bolts, and a U-shaped frame 17 is fixed to the output end of the rotating motor 15 by a pin, and the inner walls of the through holes opened on both sides of the U-shaped frame 17 are rotatably connected to the insertion rod 4, and the circumferential outer wall of the insertion rod 4 is connected to the worm gear 9 by a key, and the outer wall of one side of the U-shaped frame 17 is rotatably connected to the worm 8, and the worm 8 and the worm gear 9 are meshed with each other, and a accommodating block 19 is welded to the circumferential outer wall of the insertion rod 4, and the accommodating block 19 and the connecting frame 18 are fixedly connected, and the bottom outer wall of the base 1 is rotatably connected to the universal wheel 2;

[0066] The universal wheel 2 is provided to facilitate moving the entire device to the trenching location. The screw slide 3 can drive the pad 16 to move in the vertical direction to adjust the height of the trenching saw blade 52. The rotating motor 15 can drive the U-shaped frame 17 to rotate. When it is necessary to make a bevel cut on the wall, the trenching angle of the trenching saw blade 52 can be adjusted. The worm gear 9 can be rotated by rotating the worm 8, and the rotation angle of the connecting frame 18 in the longitudinal direction can be adjusted.

[0067] Furthermore, the outer circumferential wall of the roller 53 is fixed with a hollow shell 20 via a pin, and the inner wall of the hollow shell 20 is rotatably connected with a universal ball 21;

[0068] By providing the universal ball 21, when the roller 53 needs to adjust the grooving angle of the grooving saw blade 52, the universal ball 21 can be used to roll along the wall surface to adjust the cutting position of the grooving saw blade 52, thereby reducing the friction between the roller 53 and the wall surface.

[0069] When the embodiment is in use, when it is necessary to trench the wall surface, the universal wheel 2 is first used to move the entire device to the trenching location, and then the screw slide rail 3 is used to adjust the height of the trenching saw blade 52. In the initial stage, there is a certain gap between the trenching saw blade 52 and the wall. Then the electric telescopic rod 10 is used to drive the L-shaped plate 11 to move. During this process, the guide plate 25 drives the toggle column 38 by using the inclined hole in the guide hole 22 opened on its surface during the movement, so that the trenching saw blade 52 gradually approaches the wall surface. After the trenching saw blade 52 contacts the wall, the trenching motor 14 is used to drive the trenching saw blade 52 to rotate to trench the wall.

[0070] During the trenching process, the roller 53 rolls along the wall surface. During the rolling process, the swing arm 5 is used to convert the circular motion of the roller 53 into the linear reciprocating motion of the conical scraper 31. The conical scraper 31 scrapes off the particles in the groove during the reciprocating motion to ensure the flatness of the groove. When it is necessary to clean the particles in a certain area of ​​the groove, the base 24 is driven to move horizontally so that the base 24 and the clamping head 34 are engaged. The trenching motor 14 is used to drive the roller 53 to rotate, and at the same time, the roller 53 and the wall surface are separated. During the idling process, the roller 53 makes the conical scraper 31 reciprocate to clean the particles in the groove.

[0071] Embodiment 2:

[0072] A wall trenching device with a cleaning function, such as Figures 1 to 8 As shown, in order to facilitate the collection of scraped particles; this embodiment makes the following supplements on the basis of embodiment 1: the inner wall of the through hole opened on the surface of the slide 39 is slidably connected with a slide column 41, and the inner wall of one side of the slide column 41 and the outer wall of one side of the slide 39 are fixed with a same spring 1 40 by a pin, one end of the slide column 41 is fixed with a door-shaped plate 48 by a pin, and the through holes opened on both sides of the door-shaped plate 48 are rotatably connected with rotating sheets 44, and the inner wall of the through hole opened on the surface of the rotating sheet 44 is slidably connected with an absorption tube 47, and one end of the absorption tube 47 is fixed with a cross wheel 46 by a pin, and the outer wall of one side of the cross wheel 46 and the outer wall of one side of the rotating sheet 44 are fixed with a same spring 2 45 by a pin, the inner wall of the through hole opened on the surface of the door-shaped plate 48 is slidably connected with a trigger plate 42, and the inner wall of the through hole opened on the surface of the trigger plate 42 is fixed with a dust suction tube 43 by an embedded manner, and one end of the dust suction tube 43 and the absorption tube 47 are rotatably connected;

[0073] The two groups of cross wheels 46 are cross-stacked and arranged. When it is necessary to collect the particles scraped off by the conical scraper 31, the elastic force of the second spring 45 is used to keep the outer walls of the two groups of cross wheels 46 and the side walls of the groove in close contact, thereby reducing the gap between them and the groove and preventing the particles from overflowing. When collecting the particles, one end of the dust suction pipe 43 is connected to the vacuum cleaner by a joint, and the suction force of the vacuum cleaner is used to suck the particles through the gap between the two cross-arranged cross wheels 46. The spring 1 40 ensures the fit between the circumferential outer wall of the cross wheel 46 and the bottom of the groove. At the same time, the cross wheel 46 and the groove move in a rolling manner, thereby effectively reducing the friction between the cross wheel 46 and the groove.

[0074] Furthermore, a guide plate 51 is welded to the outer wall of one side of the slideway 39, and a bump 50 is welded to the surface of the guide plate 51, and a push plate 49 is fixed to one end of the trigger plate 42 by a pin;

[0075] When the slide column 41 slides relative to the slideway 39 and the push plate 49 moves to the protrusion 50, the protrusion 50 squeezes the push plate 49, causing one of the cross wheels 46 to slide relative to the other cross wheel 46, and a small amount of particles stuck in the gap between the two cross wheels 46 are cleared, preventing the particles from clogging the gap between the two cross wheels 46.

[0076] The above is a preferred specific embodiment of the present invention, but it is not the only specific embodiment of the present invention. Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the existing technology or public common sense within the spirit and principle of the present invention should be covered by the protection scope of the present invention.
