Description

Technical Field

[0001] The present application relates to the technical field of road surface repair, and more specifically, to automatic road pothole repair equipment. Background Art

[0002] On roads that have been used for a long time, the road surface is often damaged and potholes and cracks appear. At this time, pothole road repair equipment is needed. However, when the existing pothole road repair equipment is used, it is filled with concrete, and then the concrete is poured into the potholes and cracks on the road surface to repair them. After the repair is completed, the ordinary pothole road repair equipment needs to be manually cleaned from the remaining concrete inside the pothole road repair equipment to prevent it from solidifying inside. The manual cleaning method is time-consuming and labor-intensive, inefficient, and difficult to clean in time.

[0003] The document with the prior art publication number CN 219297930 U provides a pothole road repairing device. The device can clean the residual concrete on the inner wall of the material box without manual removal by setting a motor and a cleaning disk and drop it down in time for recycling, which saves time and effort and has high cleaning efficiency. By setting a stirring plate and other components, the concrete at the material box discharge port can have high fluidity, which is convenient for the concrete to drop down better and faster, and can also prevent the discharge port from being blocked. Moreover, the concrete in the material box can fall out of the material box faster under the pressure of the descending cleaning disk, thereby accelerating the efficiency of road repairing.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device cleans the bottom wall of the cleaning disk, each stirring plate can only clean the rotating area, so there will be a problem of cleaning dead corners, resulting in incomplete cleaning of the bottom wall of the cleaning disk.

[0005] In view of this, we propose automatic road pothole repair equipment. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The purpose of the present application is to provide an automatic road pothole repairing device, which solves the technical problems in the above-mentioned background technology and achieves a technical effect of more thoroughly cleaning the bottom wall of the scraper and avoiding cleaning dead corners.

[0009] The technical solution of the present application provides an automatic pothole repairing device, comprising a cart and a material barrel fixed on the cart, a feed hopper is provided on the upper side wall of the material barrel, a discharge pipe with a valve is provided on the bottom of the material barrel, a radially arranged scraper is fixedly installed at the lower part of the interior of the material barrel, a scraper disk that fits the inner wall is slidably provided inside the material barrel, and a lifting mechanism that can drive the scraper disk to rise and fall is rotatably connected to the upper end of the material barrel.

[0010] By adopting the above technical solution, when it is necessary to add material into the material barrel, the lifting mechanism drives the scraper plate to rise and is placed at the upper end of the connection between the feed hopper and the material barrel to ensure the normal addition of materials. The materials are discharged through the discharge pipe, and when it is necessary to clean the inner wall of the material barrel, the lifting mechanism drives the scraper plate to descend, and the scraper plate scrapes and cleans the inner wall of the material barrel. After the scraper plate and the scraper plate are butted against each other, the lifting mechanism is rotated to make the scraper plate fit the scraper plate and rotate. The scraper plate passes through the axis of the material barrel, and then when the scraper plate rotates, the scraper plate can clean the bottom wall of the scraper plate without dead angles, thereby ensuring that the bottom of the scraper plate is cleaned more thoroughly.

[0012] By adopting the above technical solution, the servo motor is a servo motor with a brake, and the tooth plate passes through the cover plate. When the servo motor drives the gear to rotate clockwise, the tooth plate rises, and when the servo motor drives the gear to rotate counterclockwise, the tooth plate falls. The rotation of the lifting mechanism can be realized by rotating the cover plate.

[0013] As an optional solution to the technical solution of the present application document, flanges are fixedly installed on both upper and lower ends of the cover plate, and a handle is fixedly installed on the cover plate.

[0014] By adopting the above technical solution, the cover plate is connected to the material barrel in rotation by means of flanges fixed at the upper and lower ends of the cover plate, and a handle is fixed at the upper edge of the cover plate to facilitate the rotation of the cover plate.

[0015] As an optional solution to the technical solution of the present application document, a limiting disk is fixedly installed on the lower end of the tooth plate.

[0016] As an optional solution to the technical solution of the present application document, the scraper is coaxially fixed with a guide rod slidably inserted in the lower end of the tooth plate, a spring is fixedly installed between the tooth plate and the scraper, and the scraper is symmetrically fixed with a positioning rod passing through the limit plate.

[0017] By adopting the above technical solution, when the tooth plate descends, the scraper disc rests on the scraper plate and the guide rod slides in the tooth plate, and the spring is compressed. Under the action of the spring, it can not only play a buffering role, but also ensure the fit between the scraper disc and the scraper plate. The positioning rod penetrates the limit plate to ensure that when the tooth plate rotates, the scraper disc is driven to rotate under the joint action of the positioning rod and the limit plate.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] The automatic road pothole repairing equipment includes a cart 1 and a material barrel 2 fixed on the cart 1, a feed hopper 202 is provided on the upper side wall of the material barrel 2, a discharge pipe 203 with a valve is provided at the bottom of the material barrel 2, a radially arranged scraper 201 is fixedly installed at the lower part of the interior of the material barrel 2, a scraper plate 4 that fits the inner wall is slidably provided inside the material barrel 2, and a lifting mechanism 3 that can drive the scraper plate 4 to rise and fall is rotatably connected to the upper end of the material barrel 2.

[0029] Reference Figure 1-Figure 5 When it is necessary to add material to the material barrel 2, the lifting mechanism 3 drives the scraper 4 to rise and is placed at the upper end of the connection between the feed hopper 202 and the material barrel 2 to ensure the normal addition of materials. The materials are discharged through the discharge pipe 203, and when it is necessary to clean the inner wall of the material barrel 2, the lifting mechanism 3 drives the scraper 4 to descend, and the scraper 4 scrapes and cleans the inner wall of the material barrel 2. When the scraper 4 and the scraper plate 201 are against each other, the lifting mechanism 3 is rotated to make the scraper 4 fit the scraper plate 201 and rotate. The scraper plate 201 passes through the axis of the material barrel 2, and then when the scraper 4 rotates, the scraper plate 201 can clean the bottom wall of the scraper 4 without dead angles, thereby ensuring that the bottom of the scraper 4 is cleaned more thoroughly.

[0030] The lifting mechanism 3 includes a cover plate 304 rotatably connected to the top of the material barrel 2, a servo motor 301 fixed on the cover plate 304, a gear 302 coaxially fixed to the output shaft of the servo motor 301, and a tooth plate 303 meshing with the gear 302 and parallel to the axial direction of the material barrel 2, and the lower end of the tooth plate 303 is connected to the scraper 4.

[0031] Reference Figure 3 The servo motor 301 is a servo motor 301 with a brake, and the tooth plate 303 penetrates the cover plate 304. When the servo motor 301 drives the gear 302 to rotate clockwise, the tooth plate 303 rises, and when the servo motor 301 drives the gear 302 to rotate counterclockwise, the tooth plate 303 falls. The rotation of the cover plate 304 can realize the rotation of the lifting mechanism 3.

[0032] Flanges 3041 are fixedly mounted on both upper and lower ends of the cover plate 304 , and a handle 3042 is fixedly mounted on the cover plate 304 .

[0033] Reference Figure 2 and Figure 5 The flanges 3041 fixed at the upper and lower ends of the cover plate 304 are used to realize the rotation connection between the cover plate 304 and the material barrel 2. The handle 3042 is fixed on the upper edge of the cover plate 304 to facilitate the rotation of the cover plate 304.

[0034] A limit plate 3031 is fixedly mounted on the lower end of the tooth plate 303 .

[0035] The scraper 4 is coaxially fixed with a guide rod 401 which is slidably inserted in the lower end of the tooth plate 303 , a spring 402 is fixedly installed between the tooth plate 303 and the scraper 4 , and the scraper 4 is symmetrically fixed with a positioning rod 403 which passes through the limit plate 3031 .

[0036] Reference Figure 3 When the tooth plate 303 descends, the scraper 4 rests on the scraper plate 201 and makes the guide rod 401 slide in the tooth plate 303, and the spring 402 is compressed. Under the action of the spring 402, it can play a buffering role, and secondly, it can ensure the fit between the scraper 4 and the scraper 201, and the positioning rod 403 penetrates the limit plate 3031 to ensure that when the tooth plate 303 rotates, the scraper 4 is driven to rotate under the joint action of the positioning rod 403 and the limit plate 3031.

[0037] Working principle: when it is necessary to add material to the material barrel 2, the servo motor 301 drives the gear 302 to rotate clockwise, the tooth plate 303 rises, and pulls the scraper 4 up, so that the scraper 4 is placed at the upper end of the connection between the feed hopper 202 and the material barrel 2. When it is necessary to clean the inner wall of the material barrel 2, the servo motor 301 drives the gear 302 to rotate counterclockwise, the tooth plate 303 descends, and the lower surface of the cover plate 304 is attached to the scraper 201, and finally the handle 3042 is turned.
