Description

Technical Field

[0001] The utility model relates to an asphalt gravel synchronous sealing vehicle, in particular to a fiber spreading box used for the asphalt gravel synchronous sealing vehicle. Background Art

[0002] Asphalt chip seal is a waterproof bonding layer used in the construction of roads, airport runways and bridge pavements. As fiber asphalt chip seal technology sandwiches fibers in the seal, such as glass fiber, basalt fiber and other reinforcing materials, it improves the waterproof, crack resistance and service life of the pavement, and has been widely promoted by road administration departments in recent years.

[0003] The fiber spreading box in the previous asphalt macadam synchronous sealing vehicle has a relatively complex fiber cutting structure. Generally, the cutter wheel and the driven wheel are connected together. In order to maintain close contact between the driven wheel and the cutter wheel, a clamping device needs to be set on the connecting arm of the cutter wheel. After a long time, the device is easy to loosen and needs to be adjusted in real time. Moreover, each time the fiber is re-pulled through the driven wheel and the cutter wheel, the cutter wheel or the driven wheel needs to be moved so that there is a gap between them for the fiber to pass through, which is not conducive to the operation of workers. Summary of the invention

[0004] The utility model aims to solve the above-mentioned shortcomings and provides a fiber spreading box for an asphalt gravel synchronous sealing vehicle, which comprises an upper box body and a lower box body arranged at the bottom of the upper box body, a cutter wheel is installed at the bottom of the upper box body, a transmission mechanism matching with the cutter wheel is installed on the upper box body through a rotating shaft, a fiber tube is also installed on the upper box body, and the cutter wheel is driven to rotate by a motor;

[0005] The transmission mechanism comprises two left and right mounting plates of the same structure, a driven wheel is mounted between the two mounting plates via a transmission shaft, an L-shaped connecting plate is mounted between the two mounting plates via a second rotating shaft, a transition wheel is mounted on the connecting plate via a fixing column, a torsion spring is also arranged on the second rotating shaft, and both ends of the torsion spring are respectively connected to the connecting plate and the mounting plate;

[0006] A cylinder 1 is also installed on the side wall of the upper box body, and the piston end of the cylinder 1 is in contact with the transmission mechanism.

[0007] In order to facilitate the fiber to pass through the driven wheel and the cutter wheel better, the outlet of the fiber tube is located directly above the transition wheel.

[0008] In order to keep the transition wheel in close contact with the driven wheel and the cutter wheel, a return spring is further arranged on the connecting plate, and the other end of the return spring is connected to the side wall of the upper box body.

[0009] In order to prevent debris from entering the box and to facilitate maintenance, a box cover is hinged on the top of the upper box body, a cylinder 2 is installed between the box cover and the side wall of the upper box body, and a handle is installed on the box cover.

[0010] In order to make the transition wheel rotate better with the cutter wheel and the driven wheel, while reducing the wear on the fixed column and extending its service life, bearings are arranged on both sides of the fixed column, and the transition wheel is installed on the bearings.

[0011] In order to make the driven wheel rotate better and reduce the wear of the cutter wheel, the driven wheel is connected to the transmission shaft through a second bearing, and the driven wheel is made of rubber.

[0012] In order to prevent the fallen fibers from being blown into the box again, an adjustable baffle is arranged in the lower box.

[0013] In order to make the fibers fall down better and prevent them from floating around in the fiber box, an air blowing pipe is further provided on the upper box body, and an air vent facing the lower box body is opened at the bottom of the air blowing pipe.

[0014] The utility model has the following beneficial effects:

[0015] The utility model drives the driven wheel to be in close contact with the cutter wheel through the cylinder, which can ensure that the contact is tighter and the fibers are cut off at the same time, the contact stability is better and the structure is simpler.

[0016] The utility model adds a torsion spring, which can ensure the close contact between the transition wheel, the driven wheel and the cutter wheel, so that the fiber can be better pulled between the cutter wheel and the driven wheel to avoid entanglement. The utility model has a simple structure and is conducive to popularization and use.

[0017] When the utility model pulls the fiber through the cutter wheel and the driven wheel, the cylinder retracts and the return spring pulls the transmission mechanism to the left. At this time, a gap appears between the cutter wheel and the driven wheel, which facilitates the fiber to pass through. This structure makes the fiber passing method simpler, is convenient for workers to operate, and is conducive to improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The transmission mechanism 10 includes two left and right mounting plates 101 of the same structure, a driven wheel 13 is mounted between the two mounting plates 101 via a transmission shaft 107, an L-shaped connecting plate 104 is also mounted between the two mounting plates 101 via a second rotating shaft 108, a transition wheel 5 is mounted on the connecting plate 104 via a fixing column 106, a torsion spring 103 is also arranged on the second rotating shaft 108, and both ends of the torsion spring 103 are respectively connected to the connecting plate 104 and the mounting plate 101;

[0026] A cylinder 12 is also installed on the side wall of the upper box body 1, and the piston end of the cylinder 12 is in contact with the transmission mechanism 10.

[0027] Through the above technical solution, the tightness of the contact between the driven wheel 13 and the cutter wheel 4 can be controlled by the cylinder 12, and at the same time, the transition wheel 5 can be pressed toward the driven wheel 13 and the transition wheel 5 by the torsion spring 103 to keep them in close contact.

[0028] The outlet of the fiber tube 9 is located just above the transition wheel 5 .

[0029] Through the above technical solution, the fiber can better pass through the transition wheel 5, the driven wheel 13 and the cutter wheel 4.

[0030] A return spring 105 is also disposed on the connecting plate 104 , and the other end of the return spring 105 is connected to the side wall of the upper box body 1 .

[0031] Through the above technical solution, when the cylinder 12 retracts, the return spring 105 can pull the transmission mechanism 10 to the left faster, so that the driven wheel 13 and the cutter wheel 4 are separated, and the fiber yarn passes through the driven wheel 13 and the cutter wheel 4 better when being pulled.

[0032] A box cover 7 is also hinged on the top of the upper box body 1 , a cylinder 6 is installed between the box cover 7 and the side wall of the upper box body 1 , and a handle 8 is installed on the box cover 7 .

[0033] Through the above technical solution, the handle 8 is provided, so that the box cover 7 can be opened better. At the same time, through the provision of the cylinder 2 6, the box cover 7 can be more stable when closed.

[0034] Bearings 109 are provided on both sides of the fixing column 106 , and the transition wheel 5 is installed on the bearings 109 .

[0041] Through the above technical solution, air can be blown toward the lower box 2 through the blowing tube 11, so that the fibers fall downward faster.

[0042] During operation, the cylinder 12 retracts, and the fiber passes through the fiber tube 9 and bypasses the transition wheel 5, and passes between the driven wheel 13 and the cutter wheel 4. The cylinder 12 extends, so that the driven wheel 13 and the cutter wheel 4 abut each other. At this time, the motor of the cutter wheel 4 is started to drive the cutter wheel 4 to rotate. Since the transition wheel 5 and the driven wheel 13 are in contact with the cutter wheel 4, under the action of friction, the cutter wheel 4 drives the transition wheel 5 and the driven wheel 13 to rotate, and at the same time plays the role of pressing the fiber, conveying the fiber and cutting the fiber. The design structure is simpler, more practical, and is conducive to popularization and use.
