The baffle is connected with the supporting rod; when the supporting rod is located at the first angle, the baffle is driven to cancel blocking work on the discharging opening; when the supporting rod is located at the second angle, the baffle is driven to block the discharging opening, and therefore the discharging opening is blocked through the baffle when the crack pouring device is in the moving process (one crack is repaired, and the device is transferred to the next crack), and resource waste caused by the fact that a repairing agent flows out is avoided.

Description

Technical Field

[0001] This utility model relates to the field of road construction equipment, and in particular to a road crack sealing device. Background Technology

[0002] Road crack sealing devices are mechanical equipment used to fill road cracks and prevent road surface damage. There are various types of road repair devices, including asphalt repair trucks for repairing large cracks and simple repair buckets for repairing small cracks.

[0003] The existing repair bucket includes a hopper and a hand handle. During the repair process, the repair agent (asphalt, concrete, etc.) is introduced into the hopper, and the hand handle is used to align the discharge port of the hopper with the crack to fill it.

[0004] However, the existing hopper does not have a structure to seal the discharge port. This means that when the repair bucket switches between cracks (after one crack is repaired, the device moves to the next crack), the repair agent will fall from the discharge port, causing unnecessary waste.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this utility model is to provide a road crack sealing device that can use a baffle to seal the material discharge opening during the process of the sealing device moving (after one crack is repaired, the device moves to the next crack), thereby preventing the repair agent from flowing out and causing resource waste.

[0007] To achieve the above objectives, this utility model provides a road crack sealing device, including a hopper with a material discharge opening on its bottom plane and a support rod rotatably connected thereto; a positioning structure is provided at the rotatable connection of the support rod to position its rotation angle; a material inlet is provided on the side wall of the hopper; a baffle is movably disposed inside the hopper to block the material discharge opening; the baffle is connected to the support rod; when the support rod is at a first angle, it drives the baffle to cancel the blocking of the material discharge opening; when the support rod is at a second angle, it drives the baffle to block the material discharge opening.

[0008] According to the road crack sealing device of this utility model, the feed inlet is located on the upper end face of the hopper; and a baffle plate is inserted perpendicular to the feed inlet.

[0009] According to the road crack sealing device of this utility model, the baffle is fixedly connected to the end of the support rod.

[0010] According to the road crack sealing device of this utility model, a connecting cylinder is provided on the hopper, and a rotating shaft is provided at the end of the support rod and rotatably sleeved inside the connecting cylinder.

[0011] According to the road crack sealing device of this utility model, the positioning structure includes a plurality of positioning grooves opened on the side wall of the end of the connecting cylinder and an insert block disposed at the end of the support rod, which is selectively inserted into the positioning groove; an elastic element for driving the rotating shaft to move along the axial direction of the connecting cylinder is disposed between the opposite end of the connecting cylinder where the positioning groove is disposed and the support rod.

[0012] According to the road crack sealing device of this utility model, the elastic element is a spring.

[0013] This invention provides a road crack sealing device, comprising a hopper with a material outlet on its bottom plane and a support rod rotatably connected thereto; the hopper has an inlet on its side wall; in use, the bottom plane of the device is in contact with the road surface, and the support rod is used to move the entire device. When repairing cracks, repair agent (asphalt, concrete, etc.) is poured into the hopper through the inlet. The support rod is used to move the device, aligning the material outlet with the crack, and the device moves along the crack's direction. During this movement, the repair agent (asphalt, concrete, etc.) flows into the crack through the material outlet, completing the repair. The inner wall of the hopper has an inclined surface that drives the repair agent to flow into the material outlet, optimizing the material flow rate and reducing the amount of repair agent retained in the hopper, thus preventing resource waste (asphalt retained in the hopper dries and cannot be used for repair). This invention uses a baffle to seal the material outlet during the movement of the sealing device (after repairing one crack, the device moves to the next crack), preventing the repair agent from flowing out and causing resource waste.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0021] See Figure 1 This utility model provides a road crack sealing device, which includes a hopper 1 with a material opening 11 on its bottom plane and a support rod 2 rotatably connected thereto; the side wall of the hopper 1 is provided with a material inlet 12; when using this crack sealing device, its bottom plane is in contact with the road surface, and the support rod 2 is held to move the whole device. When repairing the crack, the repair agent (asphalt, concrete, etc.) is poured into the internal space of the hopper 1 through the material inlet 12. The support rod 2 is used to move the device so that the material opening 11 is aligned with the crack, and the device is moved along the extension direction of the crack. During the movement, the repair agent (asphalt, concrete, etc.) will flow into the crack through the material opening 11 to complete the repair work.

[0022] See Figure 2 Preferably, the inner wall of the hopper 1 is provided with an inclined surface 6 that drives the repair agent to flow into the material opening 11, so as to optimize the material feeding speed of the repair agent and reduce the repair agent from being retained in the internal space of the hopper 1, which would cause resource waste (after the asphalt retained in the internal space of the hopper 1 dries, the repair work cannot be carried out).

[0023] The rotating connection of the support rod 2 is provided with a positioning structure to position its rotation angle;

[0024] The hopper 1 is equipped with a baffle 3 that blocks the discharge opening 11. When the equipment is in repair work, the baffle 3 is not blocked, and the repair agent in the internal space of the hopper 1 can flow out through the discharge opening 11. However, when the equipment is in the transfer process (after one crack is repaired, the device is transferred to the next crack), the baffle 3 blocks the discharge opening 11, and the repair agent in the internal space of the hopper 1 cannot flow out through the discharge opening 11.

[0025] Preferably, in order to prevent the repair agent from flowing out of the inlet 12 during the movement, the inlet 12 of this application is located on the upper end face of the hopper 1; and a baffle plate 4 is inserted perpendicularly to the inlet 12 (a slot is correspondingly provided on the hopper 1), so that the inlet 12 can be completely or partially blocked by the baffle plate 4 during the movement.

[0026] The baffle 3 is connected to the support rod 2. Figure 4(As shown); The state of the baffle 3 is switched by the support rod 2, which is convenient to operate and avoids the repair agent from coming into contact with the body, such as being burned by hot asphalt.

[0027] See Figure 2 and Figure 3 When the support rod 2 is at the first angle (in this embodiment, the angle is 45° with the bottom plane of the hopper 1), it drives the baffle 3 to cancel the blocking of the material discharge opening 11.

[0028] When the support rod 2 is at the second angle (in this embodiment, the support rod 2 in this state is parallel to the bottom plane of the hopper 1), it drives the baffle 3 to block the discharge opening 11.

[0029] See Figure 5 The specific connection structure is as follows: the baffle 3 is fixedly connected to the end of the support rod 2 (the fixed connection method can be welding or other methods). A connecting cylinder 21 is provided on the hopper 1, and a rotating shaft 22 is provided at the end of the support rod 2, which is rotatably sleeved inside the connecting cylinder 21. The positioning structure includes multiple positioning grooves 23 formed on the side wall of the end of the connecting cylinder 21 and an insert block 24, one of which is inserted into the positioning groove 23 at the end of the support rod 2.

[0030] An elastic element 5 (which can be a spring) is provided between the opposite end of the positioning groove 23 and the support rod 2, which drives the rotating shaft 22 to move along the axial direction of the connecting cylinder 21.

[0031] When adjusting the angle of the support rod 2, hold the support rod 2 and move its pivot 22 along the axis of the connecting cylinder 21 so that the insert 24 is disengaged from the original positioning groove 23. At this time, the support rod 2 is in a rotatable state. Then, after rotating to the position of the corresponding positioning groove 23, release the pressure on the support rod 2. Under the action of the elastic element 5, the support rod 2 causes the insert 24 to be inserted into the new positioning groove 23.

[0032] In summary, this utility model provides a road crack sealing device, including a hopper with a material outlet on its bottom plane and a support rod rotatably connected to it; the hopper has a material inlet on its side wall; when in use, the bottom plane of this pipe crack sealing device is in contact with the road surface, and the support rod is used to move the entire device. During pipe crack repair, repair agent (asphalt, concrete, etc.) is poured into the hopper through the material inlet. The support rod is used to move the device so that the material outlet is aligned with the crack, and the device moves along the direction of the crack's extension. During this movement, the repair agent (asphalt, concrete, etc.) flows into the crack through the material outlet, thus completing the repair work. The inner wall of the hopper is provided with an inclined surface that drives the repair agent to flow into the material outlet, optimizing the material discharge speed and reducing the amount of repair agent retained in the hopper's internal space, thus preventing resource waste (asphalt retained in the hopper's internal space dries and cannot be used for repair). This invention uses a baffle to seal the material discharge opening during the crack filling device's movement (after one crack is repaired, the device moves to the next crack), preventing the repair agent from flowing out and causing resource waste.

[0033] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
