[0018] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0019] Example

[0020] The road crack treatment device described in this embodiment is used for road engineering. Figure 1 As shown, it comprises a frame 1 which is connected to each other from top to bottom, and at least three universal wheels 9 are installed at the bottom of the frame 1 to facilitate movement so as to facilitate repairing cracks of different shapes and positions;

[0021] The frame 1 is provided with a storage hopper 2 that slides up and down with the frame 1. The top of the storage hopper 2 is hinged with a push rod 3 that swings left and right, so that the push rod 3 can push the frame 1 and press the storage hopper 2, so that the storage hopper 2 slides up and down in the frame 1.

[0022] The bottom of the storage hopper 2 is provided with a feeding port communicating with each other up and down, and a guide plate 10 is provided at the bottom of the storage hopper 2 below the feeding port, and a first baffle 11 is provided at the open end of the guide plate 10 to close it. The horizontal height of the bottom end of the first baffle 11 is lower than the horizontal height of the bottom end of the guide plate 10, and the top end of the first baffle 11 is hinged to the bottom of the storage hopper 2 to swing left and right. A connecting component for making the first baffle 11 and the guide plate 10 fit tightly together is provided on the guide plate 10, so that the storage hopper 2 is pressed downward by the push rod 3 until the first baffle 11 contacts the ground, and then the frame 1 is pushed left and right to move the first baffle 11 outward to open the guide plate 10, so that the asphalt and other repairing fluids in the storage hopper 2 enter the cracks through the guide plate 10 to complete the repair;

[0023] The connecting assembly includes at least two tension springs 12, which are respectively installed on the front and rear sides of the guide plate 10 to connect the guide plate 10 and the first baffle 11;

[0024] The connection may further include a third spring, which is mounted between the outer side wall of the first baffle 11 and the bottom of the storage hopper 2;

[0025] The bottom of the storage hopper 2 near the first baffle 11 is provided with a collection assembly for injecting overflowed asphalt into the crack. When the crack width is smaller than the width of the guide plate 10 or the crack is full and overflowing, asphalt on both sides of the crack can be scraped into the crack. This not only reduces waste and environmental pollution, but also increases the compactness of the injected asphalt. After the crack is filled, the surface can be scraped flat to improve the appearance.

[0026] The contact end of the guide plate 10 and the first baffle 11 is provided with a cushion layer for increasing sealing and buffering, thereby improving sealing while reducing wear and noise generated by collision when the first baffle 11 and the guide plate 10 are in contact.

[0027] The left and right inner walls of the frame 1 are vertically provided with slide grooves, and a guide rod 6 is vertically arranged in the slide groove. A connecting block 7 is provided on the guide rod 6 to slide with it up and down, and the connecting block 7 is fixed to the side wall of the storage hopper 2. A first spring 8 is provided on the guide rod 6 below the connecting block 7, which is convenient for increasing the push rod 3 to slide downward. After the downward pressing force disappears or decreases, it slides upward under the drive of the first spring 8, thereby avoiding the guide plate 10 from always contacting the ground, causing asphalt leakage in the storage hopper 2, resulting in waste and environmental pollution.

[0028] like Figure 3 As shown, the collecting assembly includes a fixing groove 14, which is vertically fixed to the bottom of the storage hopper 2. A first through hole communicating with the upper and lower parts is opened at the bottom of the fixing groove 14, and a connecting rod 17 is independently installed in the first through hole. A second baffle 16 for preventing it from falling out of the fixing groove 14 is horizontally fixed on the connecting rod 17 located in the fixing groove 14, and a second spring 15 is vertically installed between the second baffle 16 and the storage hopper 2. In the natural state, the bottom end of the scraper 13 is at the same horizontal height as the bottom end of the first baffle 11, so that when the storage hopper 2 is pressed downward by the push rod 3, the first baffle 11 and the scraper 13 are in contact with the ground at the same time, so that the asphalt overflowing from the crack and on both sides of the crack can be scraped into the crack again during the movement of the frame 1. When the crack is full, it is scraped flat by the scraper 13 and collected together for centralized processing;

[0029] The collecting assembly may further include at least two fixing grooves 14, the fixing grooves 14 being vertically fixed to the bottom of the storage hopper 2, each having a first through hole communicating with the top and the bottom, each having a connecting rod 17 independently inserted therein, a second baffle 16 being horizontally fixed on the connecting rod 17 located in the fixing groove 14 to prevent it from falling out of the fixing groove 14, and a second spring 15 being vertically installed between the second baffle 16 and the storage hopper 2 to further improve stability and service life during use;

[0030] The fixing groove 14 can also be threadedly matched with the bottom of the frame 1, which is convenient for disassembly, maintenance and replacement, further improving the scraping and collecting effects while increasing the service life and reducing the cost of use to a certain extent.

[0031] like Figure 4 As shown, the push rod 3 is in a "Y"-shaped structure as a whole, and the forked end of the push rod 3 is connected to the top of the frame 1 through the clamping block 4. The forked end of the push rod 3 is hinged to the top of the clamping block 4 and swings left and right. The clamping block 4 is in a "C"-shaped structure as a whole and is buckled on the top of the frame 1 and slides left and right with it. A second threaded through hole is provided on the side wall of the clamping block 4, which is connected front and back. A screw threadedly matched with it is installed in the second threaded through hole, which is convenient for the push rod 3 to swing left and right, and also convenient for adjusting the position of the clamping block 4 according to needs, so as to facilitate the operator to push the frame 1 and press the storage hopper 2.

[0032] like Figure 2 As shown, the scraper 13 is a semicircular ring structure as a whole, and the width of the first baffle 11 is smaller than the diameter of the scraper 13, which is convenient for scraping and collecting the asphalt flowing out of the guide plate 10 and overflowing from the cracks. After being scraped by the guide plate 10, the asphalt on both sides of the cracks is scraped and collected again, which is convenient for further improving the injection effect and compaction degree, and making the repaired cracks more beautiful.

[0033] The outer side walls at both ends of the guide rod 6 are provided with external threads, a third threaded blind hole that is threadedly matched with the guide rod 6 is provided at the bottom of the frame 1, and a fourth through hole for the guide rod 6 to pass through is provided at the top of the frame 1. A nut 5 that is threadedly matched with the guide rod 6 is mounted on the guide rod 6 located above the frame 1, and the diameter of the fourth through hole is smaller than the diameter of the nut 5, which makes it easy to disassemble the storage hopper 2, the guide rod 6 and the first spring 8 from the frame 1, thereby facilitating maintenance and replacement, thereby increasing their service life.

[0034] The cross section of the guide plate 10 is in the shape of a right triangle, and the open end is located at its right angle surface, which not only facilitates the rapid flow of asphalt in the storage hopper 2 into the crack, but also facilitates close contact with the first baffle 11 for sealing;

[0035] The guide plate 10 has a triangular groove structure, which can be formed as a whole or by splicing three triangular plates.

[0036] Working principle: first inject asphalt or other repair fluid into the storage hopper 2, then push the frame 1 to move to the crack through the push rod 3, so that the first baffle 11 and the scraper 13 are located just above the crack, and then press the storage hopper 2 through the push rod 3 to make the storage hopper 2 slide downward until the first baffle 11 and the scraper 13 are in contact with the ground, and then push the frame 1 forward through the push rod 3 while keeping the first baffle 11 and the scraper 13 in contact with the ground, so that the guide plate 10 swings backward under the friction of the ground, and then the guide plate 10 opens to flow the asphalt into the crack, and when the frame 1 moves past During the filling process, the asphalt overflowing from the crack and on both sides of the crack will first be scraped into the crack by the first baffle 11, and will be scraped flat to squeeze the asphalt in the crack. Then, the asphalt overflowing from both sides of the guide plate 10 will be scraped into the crack again by the scraper 13. When the crack is full, it will be scraped flat again by the scraper 13, and the excess asphalt will be collected together for centralized processing. After the filling is completed, the push rod 3 is lifted to make the storage hopper 2 slide upward under the drive of the first spring 8. When the storage hopper 2 slides upward, the first baffle 11 swings forward driven by the tension spring 12 until the guide plate 10 is closed.
