Description

Technical Field

[0001] The invention relates to a soil filling device, in particular to a tire rapid soil filling device. Background Art

[0002] Scrap tire retaining walls are an effective way to utilize scrap tires. Traditional tire retaining walls utilize the soil inside the entire tire as the main structure. However, in most tire retaining wall construction scenarios, clay is used as the fill material, which makes it difficult for workers to fully fill the inner circumference of the tire during the filling process, resulting in hollowing inside the filled tire. To achieve a sufficient fill, workers must repeatedly fill and compact the soil, which not only wastes manpower but also significantly reduces construction efficiency. When the tire sidewall is cut to improve the fill efficiency, the tire sidewall is cut and released, generating a large amount of harmful gases. This damages the integrity of the tire, thus affecting its strength, polluting the environment, and preventing the removed sidewall from being effectively utilized. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a tire rapid soil filling device that improves the efficiency of filling soil in tires, reduces labor costs and avoids cutting tires.

[0004] Technical solution: The tire rapid soil filling device described in the present invention includes a housing, a drive motor, a driving gear and a driven gear meshing with each other in the housing, and an intermittent forward and reverse driven gear meshing with the driving gear and the driven gear; the driven gear is coaxially fixed to a rotating disk, a guide rail frame is fixed in the housing, a push rod is slidably installed in the guide rail frame, an arc plate is fixed to the top of the push rod, and the rotating disk is connected to the bottom end of the push rod through a support rod.

[0005] Furthermore, fan-shaped cylindrical pins are evenly fixed to the driving and driven gears and connected to the gear centers. These cylindrical pins mesh with the driven gears. The fan-shaped cylindrical pins intermittently mesh with the driven gears, driving the driven gears to achieve periodic forward and reverse rotation.

[0006] Furthermore, sector gears are fixed to the driving gear and the driven gear respectively, and the sector gears mesh with the driven gear. The intermittent meshing of the sector gears and the driven gear is smoother, driving the driven gear to achieve periodic forward and reverse rotation.

[0007] Furthermore, the rotating disk is a star-shaped rotating disk, a bayonet coaxially connected to the driven gear is provided at the center of the rotating disk, and a connecting groove connected to the bottom end of the support rod is provided at each corner of the rotating disk.

[0008] Furthermore, a contact bearing is provided at the center of the guide rail frame and guide rails are evenly arranged around the center, and the ejector rod is matched with the guide rails and slidably installed. The guide rails are used to guide the rod body of the ejector rod to slide along the guide rails.

[0009] Furthermore, the bottom end of the push rod is vertically fixed to the transmission column, and the transmission column is fixedly connected to the support rod.

[0010] Furthermore, a foot is provided at the top end of the mandrel, and the foot is welded and fixed to the arc-shaped plate. The foot increases the contact surface between the mandrel and the arc-shaped support plate, thereby enhancing the bonding strength between the two.

[0011] Furthermore, the support rods are arc-shaped support rods distributed symmetrically along the center of the rotating disk.

[0012] Furthermore, a clamping block is provided on the output shaft of the driven gear, the end of the output shaft is matched and connected with a contact bearing, and a sleeve is provided between the driven gear, the rotating disk and the guide rail frame to limit and protect each component.

[0013] Furthermore, the guide rail is in an "I-shape" and the push rod is in an "inverted concave-shaped" shape, and the guide rail and the push rod are matched and slidably installed.

[0014] Working principle: The present invention drives the driving gear to rotate clockwise by driving the motor, and drives the driven gear meshing with the driving gear to rotate counterclockwise. The driving gear and the driven gear are both provided with fan-shaped gears or fan-shaped columnar pins meshing with the driven gear; when the driven gear meshes with the fan-shaped gear or columnar pins on the clockwise rotating driving gear, the driven gear rotates counterclockwise; when the driven gear meshes with the fan-shaped gear or columnar pins on the counterclockwise rotating driven gear, the driven gear rotates clockwise, and so on alternately to achieve the rotation between the driven gears. The cam is connected to the driven gear coaxially and is connected to the bottom end of the push rod in the guide rail frame fixed in the shell through a support rod, and the top end of the push rod is fixed to the arc plate. The cam is driven by the driven gear to realize intermittent periodic forward and reverse rotation, and is driven by the support rod to drive the push rod to slide telescopically along the guide rail of the guide rail frame. When the cam rotates clockwise, the support rod approaches the cam and the push rod contracts. When the cam rotates counterclockwise, the support rod moves away from the cam and the push rod extends, driving the arc plate to push out and squeeze the filler in the tire.

[0015] Beneficial effects: Compared with the existing technology, the present invention has the following significant characteristics: 1. It can improve the filling efficiency in the tire and speed up the construction efficiency of the tire retaining wall; 2. It can reduce the construction personnel input in the filling construction and reduce labor costs; 3. It can maintain the integrity of the tire, improve the strength of the tire retaining wall, and avoid environmental pollution caused by tire cutting. BRIEF DESCRIPTION OF THE DRAWINGS
