[0026] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be further described in detail below in conjunction with the drawings.

[0027] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "center", "length", "width", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as a limitation on the utility model.

[0028] Reference Figures 1-4 The utility model embodiment provides an anti-rutting agent adding device for asphalt pavement construction, including the feeding hopper 1 for storing anti-rutting agent, the feeding hopper 1 bottom is slidably arranged with the plugging plate 2, the plugging plate 2 is opened in with the transfer tank 3;

[0029] The transfer tank 3 has a first position for receiving the anti-rutting agent and a second position for adding the anti-rutting agent to the asphalt.

[0030] Specifically, the anti-rutting agent (for the convenience of description, hereinafter referred to as material) is a substance for improving the performance of asphalt, which is granular. When the material is added to the asphalt, it is usually temporarily stored in the feeding hopper 1 first, and then the feeding hopper 1 is controlled to open and close by mechanical equipment or the material is automatically added by screw conveying. This is the prior art, and details are not described. See the patent document with the authorization announcement number CN222160824U. One of the core innovations of the utility model embodiment is that the blocking plate 2 is slidably arranged at the bottom of the feeding hopper 1, and the transfer groove 3 is arranged on the blocking plate 2 and is matched with the outlet of the feeding hopper 1. The effect of such arrangement is that when the material is added, the transfer groove 3 is first placed in the first position (at this time, the transfer groove 3 coincides with the opening of the feeding hopper 1), and the material in the feeding hopper 1 will fall into the transfer groove 3. The transfer groove 3 can be controlled to open and close by an electric valve or the like. Then the straight-line reciprocating driving assembly switches the transfer groove 3 to the second position (at this time, the solid part of the blocking plate 2 blocks the opening of the feeding hopper 1). At this time, the outlet of the transfer groove 3 is opened to add the material in the transfer groove 3 to the asphalt. Since the size of the transfer groove 3 is certain, the amount of material added to the asphalt each time is also certain, thereby realizing the quantitative addition of the material.

[0031] Preferably, the transfer groove 3 is provided with two. Specifically, the two transfer grooves 3 are symmetrically arranged about the blocking plate 2. The effect of such arrangement is that when the blocking plate 2 is in the position in the middle of the feeding hopper 1, the solid part thereof blocks the outlet of the feeding hopper 1, at this time, the material cannot fall. When feeding is needed, one of the transfer grooves 3 is switched from the second position to the first position (at this time, the other transfer groove 3 is in the second position), when the transfer groove 3 is switched from the first position to the second position, the material in the transfer groove 3 is added to the asphalt (the other transfer groove 3 is switched from the second position to the first position to receive the material in the feeding hopper 1), when the transfer groove 3 is switched from the second position to the first position again, the other transfer groove 3 is switched from the first position to the second position. In this way, when one transfer groove 3 adds material, the other transfer groove 3 synchronously receives material, so as to realize the continuous addition of the material.

[0032] Further, the bottom of the feeding hopper 1 is provided with a hanging plate 4. Specifically, the area of the hanging plate 4 is matched with the area of the blocking plate 2 as a whole, that is, when the hanging plate 4 coincides with the blocking plate 2, the two transfer grooves 3 can be synchronously blocked. When the blocking plate 2 slides to the right side, and when the right side transfer groove 3 moves to the right side of the hanging plate 4, the opening at the bottom of the right side transfer groove 3 is opened. Conversely, when the blocking plate 2 slides to the left side, the opening at the bottom of the left side transfer groove 3 can be opened. In this way, the passive opening and closing of the bottom opening is realized synchronously during the movement of the transfer groove 3. Figure 1

[0033] ​Further, the hanging plate 4 is provided with a parallel hopper 5. Specifically, the size of the parallel hopper 5 is larger than that of the hanging plate 4, and there is a gap between the hanging plate 4 and the parallel hopper 5 for the material to fall, and when the transfer groove 3 is in the second position, the parallel hopper 5 is still below the transfer groove 3. The purpose of such arrangement is that the materials falling from the two transfer grooves 3 will all fall into the parallel hopper 5, and then be added to the asphalt through the opening at the bottom of the parallel hopper 5.

[0034] Further, a first power assembly for driving the sealing plate 2 to reciprocate is further included. The first power assembly can be an existing structure such as an electric push rod, a gas cylinder or a ball screw for providing linear driving force, so as to control the reciprocating sliding of the sealing plate 2.

[0035] Further, an auxiliary mechanism for improving the efficiency of the anti-rutting agent adding is further included. The auxiliary mechanism includes a striking rod 6, the parallel hopper 5 is fixed with a rotating seat 7, and the striking rod 6 is rotationally arranged on the rotating seat 7. Specifically, the striking rod 6 is approximately L-shaped, including a short side and a long side, the rotating seat 7 is fixed to the outer side wall of the parallel hopper 5, and the long side of the striking rod 6 is rotationally connected with the rotating seat 7. The purpose of such arrangement is that after the material in the transfer groove 3 falls into the parallel hopper 5, the striking rod 6 is driven to rotate away from the parallel hopper 5 by a motor or other driving member for providing rotary force, and then the striking rod 6 is controlled to rotate in the opposite direction, so that the end of the short side of the striking rod 6 collides with the outer side wall of the parallel hopper 5 to generate vibration, so as to avoid the material from staying on the inner wall of the parallel hopper 5 as much as possible, thereby accelerating the falling of the material.

[0036] As an alternative to the rotation of the impact rod 6 driven by the motor, a transmission rod 8 is slidably arranged on the impact rod 6, the transmission rod 8 is located on the movement stroke of the blocking plate 2, and a spring 9 is arranged between the transmission rod 8 and the impact rod 6, and a torsional spring (not shown) is arranged between the impact rod 6 and the rotating seat 7. Specifically, a sliding hole is formed on the long side of the impact rod 6, the sliding hole is arranged obliquely, the transmission rod 8 is slidably connected with the sliding hole, and extends into the hopper 5, a protrusion 10 is arranged at the end of the transmission rod 8 away from the hopper 5, one end of the spring 9 is fixedly connected with the impact rod 6, and the other end is fixedly connected with the protrusion 10, the force required for the deformation of the spring 9 is greater than the force required for the deformation of the torsional spring, and the setting has the effect that when the transfer chute 3 is switched from the first position to the second position, the side of the blocking plate 2 abuts against the end of the transmission rod 8, so that the transmission rod 8 slides along the direction of the sliding hole, that is, slides obliquely downward, and stores energy in the spring 9, so as to achieve avoidance, when the blocking plate 2 continues to slide, the side thereof is away from the transmission rod 8, at this time, the elastic force of the spring 9 is released, so that the transmission rod 8 is inserted into the transfer chute 3, when the material in the transfer chute 3 is added, the transfer chute 3 is switched from the second position to the first position, in this process, the inner wall of the transfer chute 3 abuts against the transmission rod 8, so as to drive the transmission rod 8 to swing downward, so as to achieve avoidance, since the transmission rod 8 is slidably connected with the impact rod 6, the impact rod 6 is driven to rotate away from the hopper 5, and stores energy in the torsional spring, when the blocking plate 2 is completely away from the transmission rod 8, the elastic force of the torsional spring is released, at this time, the impact rod 6 is driven to rotate reversely, and abuts against the hopper 5, the advantages brought by this are that, when the elastic force of the spring 9 is released to drive the transmission rod 8 to be inserted into the transfer chute 3, the transmission rod 8 abuts against the material in the transfer chute 3, so as to produce a dredging effect on the material in the transfer chute 3, so as to avoid the blockage of the transfer chute 3, and secondly, after the inner wall of the transfer chute 3 abuts against the transmission rod 8 to store energy in the torsional spring, the impact rod 6 is driven to rotate reversely, so as to drive the impact rod 6 to passively abut against the hopper 5, so as to improve the discharging rate.

[0037] Preferably, the end of the transmission rod 8 is provided with an arc surface, which can make the transmission rod 8 abut against the blocking plate 2 more smoothly.

[0038] Preferably, the upper hopper 1 is further provided with a cover plate 11. The cover plate 11 is fixedly connected to the outer circumferential surface of the upper hopper 1, and the size is matched with the size of the top of the hopper 5, when the transmission rod 8 is inserted into the transfer chute 3, the material can be prevented from flying out from the top of the transfer chute 3.

[0039] Preferably, the auxiliary mechanism is provided with two. Two auxiliary mechanisms are arranged symmetrically about the parallel hopper 5, so that when the two transfer troughs 3 add materials, the auxiliary mechanism on the corresponding side will collide with the parallel hopper 5, so as to improve the discharging rate.

[0040] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
