Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a rubber asphalt spreading device for road construction and maintenance. Background Art

[0002] Rubber asphalt is a modified asphalt binder material. It is made by first processing waste tire raw materials into rubber powder, then combining them according to a certain coarse and fine grading ratio, and adding a variety of high polymer modifiers. Under high temperature conditions, it is fully mixed and fully expanded with the base asphalt to form rubber powder. Rubber asphalt has high temperature stability, low temperature flexibility, aging resistance, fatigue resistance, water damage resistance and other properties. It is an ideal environmentally friendly pavement material and is mainly used in the stress absorption layer and surface layer of road structures. It is usually paved using a rubber asphalt spreading device.

[0003] In the prior art, for example, Chinese Patent CN 216427924 U discloses a rubber asphalt spreading device for road construction and maintenance. The device comprises a supporting plate with a connector fixedly mounted on the left side of the supporting plate, a tank body fixedly mounted on the top surface of the supporting plate, a feed hopper extending through the top surface of the tank body, a travel mechanism disposed on the bottom surface of the supporting plate, a stirring mechanism connected to the travel mechanism, a spreading mechanism disposed on the tank body, and a scraping mechanism disposed on the tank body. This rubber asphalt spreading device for road construction and maintenance facilitates the effective spreading and paving of asphalt by stirring the asphalt in the tank body, preventing asphalt coagulation and ensuring efficient paving. While highly practical, this patent still suffers from the following issues:

[0004] In the above-mentioned patent, although a spray nozzle is provided, the staff starts the pump to allow the asphalt in the tank to enter the conduit through the discharge pipe, and is spread on the road surface through the spray nozzle. However, different road construction scenarios have different requirements for the width and amount of asphalt spreading, and the number of spray nozzles is fixed, which may affect the quality of the spreading. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, when in use, the staff pulls the pull plate on the top of the nozzle to be used according to the needs of the scene. The pull plate drives the baffle to move through the connecting rod so that the baffle no longer blocks the top of the nozzle. When the first limit plate contacts the inner wall of the U-shaped frame, the staff rotates the handle, and the handle drives the threaded rod to rotate. The threaded rod descends along the threaded hole, and then drives the movable plate to descend until each block enters each slot respectively. At this time, each connecting rod is fixed, so that the baffle is fixed. At this time, the width of the asphalt spreading can be controlled by controlling the number of nozzles that can be used.

[0025] The effect achieved by the entire embodiment 1 is that when in use, the staff pulls the pull plate 17 on the top of the nozzle to be used according to the needs of the scene, and the pull plate 17 drives the baffle 15 to move through the connecting rod 16, so that the baffle 15 no longer blocks the top of the nozzle. When the first limit plate 19 contacts the inner wall of the U-shaped frame 13, the staff rotates the handle 24, and the handle 24 drives the threaded rod 23 to rotate. The threaded rod 23 descends along the threaded hole 22, and then drives the movable plate 25 to descend until each block 35 enters each slot 18 respectively. At this time, each connecting rod 16 is fixed, so that the baffle 15 is fixed. At this time, the width of the asphalt spreading can be controlled by controlling the number of nozzles that can be used.

[0026] Example 2, as Figure 1-Figure 5As shown, further, two fixing rods 11 are fixedly installed on the outer wall of the base 1, a connecting plate 12 is fixedly installed on the bottom of the fixing rod 11, a support plate 30 is fixedly installed on the top of the connecting plate 12, a second spring 31 is fixedly installed on the outer wall of the support plate 30, a connecting block 32 is fixedly installed on one end of the second spring 31, a limiting rod 34 is fixedly installed on the outer wall of the connecting block 32, one end of the limiting rod 34 is slidably plugged into the support plate 30, and a push plate 33 is fixedly installed on the top of the connecting block 32.

[0027] Furthermore, a scraper 26 is provided at the bottom of the connecting plate 12 , a plug plate 28 is fixedly installed on the top of the scraper 26 , a connecting port 29 is opened through the outer wall of the plug plate 28 , and an opening 27 is opened through the top of the connecting plate 12 .

[0028] Furthermore, a tank body 6 and a feed pump 7 are fixedly installed on the top of the base 1 , a connecting pipe 8 is fixedly connected between the input end of the feed pump 7 and the tank body 6 , and a discharge pipe 9 is fixedly connected between the output end of the feed pump 7 and the fixed pipe 10 .

[0029] Furthermore, a connector 2 is fixedly mounted on the outer wall of the base 1 for connection to a vehicle.

[0030] Furthermore, two fixing plates 3 are fixedly installed on the bottom of the base 1, and rotating shafts 4 are rotatably installed on the opposite sides of the two fixing plates 3. A wheel 5 is fixedly installed on one end of the rotating shaft 4 to facilitate the movement of the device.

[0031] Furthermore, the bottoms of the plurality of baffles 15 are in contact with the inner bottom surface of the fixed pipe 10 to prevent asphalt leakage.

[0032] The effect achieved by the entire embodiment 2 is that when the scraper 26 is damaged, the staff pulls the push plate 33, the connecting block 32 leaves the connecting port 29, and the second spring 31 is compressed. At this time, the plug plate 28 can be pulled out and a new plug plate 28 can be inserted into the opening 27. When the plug plate 28 contacts the inclined surface of the connecting block 32, the plug plate 28 pushes the connecting block 32 to move.

At this time, the plug plate 28 and the scraper 26 can be replaced, thereby improving the replacement efficiency.

[0033] Working Principle: During use, the operator pulls the pull plate 17 at the top of the desired nozzle according to the scenario. The pull plate 17 drives the baffle 15 to move via the connecting rod 16, so that the baffle 15 no longer blocks the top of the nozzle. When the first limit plate 19 contacts the inner wall of the U-shaped frame 13, the operator rotates the handle 24, which drives the threaded rod 23 to rotate. The threaded rod 23 descends along the threaded hole 22, which in turn drives the movable plate 25 downward until each block 35 enters its respective slot 18. At this point, each connecting rod 16 is fixed, so that the baffle 15 is also fixed. At this point, the width of the asphalt spraying can be controlled by controlling the number of nozzles that can be used. During use, the operator activates the extraction pump 7, and the asphalt enters the discharge pipe 9 from the connecting pipe 8 and is finally sprayed out of the nozzle through the fixed pipe 10. The scraper 26 is used to smooth the asphalt. When the scraper 26 is damaged, the staff pulls the push plate 33, the connecting block 32 leaves the connecting port 29, and the second spring 31 is compressed. At this time, the plug plate 28 can be pulled out and a new plug plate 28 can be inserted into the opening 27. When the plug plate 28 contacts the inclined surface of the connecting block 32, the plug plate 28 pushes the connecting block 32 to move. When the connecting port 29 moves to the side of the connecting block 32, the elastic force of the second spring 31 pushes the connecting block 32 into the connecting port 29. At this time, the plug plate 28 and the scraper 26 can be replaced, which improves the replacement efficiency.
