[0031] refer to Figures 1 to 6 As shown, a road pouring material spreading vehicle includes a tanker portion 100 , a paving trough portion 200 , a scraper portion 300 and a vibration plate portion 400 .

[0032] The tanker unit 100 is used to hold the material and drives the entire spreader forward, backward, or turn, completing the spreader's mobile function. A spreading trough 200 is located behind the discharging port of the tanker unit 100 to evenly distribute the material discharged from the tanker unit 100. This trough 200 is connected to the tanker unit 100 and is used to evenly distribute the material discharged from the tanker unit 100, ensuring that the material is evenly spread behind the vehicle body.

[0033] A scraper 300 is located on the upper rear side of the paving trough 200's outlet, used to smooth the mortar being paved. Attached to the paving trough 200, this scraper 300 is used to smooth the poured material after paving, ensuring a uniform paving thickness. Behind the scraper 300, a vibrating plate 400 is located, which reciprocates vertically to vibrate and pour the mortar into the gaps. Attached to the paving trough 200, this reciprocating motion vibrates the mortar into the gaps, improving its efficiency in pouring the mortar into the gaps in the asphalt mixture.

[0034] The tanker section 100 includes a vehicle body 110 and a capacity tank 120 mounted on the vehicle body 110. The vehicle body 110 is a self-propelled powered vehicle. The capacity tank 120 is arranged at the rear of the vehicle body 110 and is used to hold the pouring material. A feeding port 121 is provided at the upper end of the capacity tank 120, through which the externally supplied additional pouring material is added. A discharge chute 130 communicating with the interior of the tank is provided at the rear end of the capacity tank 120. The discharge port of the discharge chute 130 is opposite to the paving trough section 200. The pouring material contained in the tank is discharged from the rear end and then passes through the discharge chute 130 along the chute slope to the paving trough section 200. A flow meter 140 for measuring the mortar flow is provided at the discharge chute 130. The flow meter 140 monitors the flow of the mortar, thereby enabling precise control of the spreading amount.

[0035] The paving trough 200 comprises a trough body 210 and a connecting frame 220 fixed to the trough body 210 for mounting with the rear end of the vehicle body 110. The trough body 210 is a rectangular parallelepiped structure with an upper opening, capable of holding a small amount of pouring material. An auger 230 is installed within the trough body 210 to stir and evenly distribute the pouring material entering the trough body 210. The auger blades of the auger 230 are densely arranged to uniformly mix the cement mortar in the trough body 210, improving pouring efficiency.

[0036] A material spreading port 211 (discharge port) is provided on the rear side of the trough body 210 . The material spreading port 211 is opposite to the scraper portion 300 . The evenly distributed poured material is delivered to the ground from the material spreading port 211 , waiting to be leveled by the scraper portion 300 above.

[0037] The spiral distributor 230 includes a rotatable auger shaft 231 mounted within the trough 210 and a first drive motor 232 mounted at one end of the trough 210. The spiral distribution blades of the auger shaft 231 are densely arranged, and the output end of the first drive motor 232 is connected to one end of the auger shaft 231. The first drive motor 232 is used to provide power for the rotation of the auger shaft 231. Two symmetrically distributed auger shafts 231 are arranged within the trough 210. The two opposing auger shafts 231 can fully mix the poured material, ensuring that a substantially equal amount of poured material is discharged from each position of the material dispensing port 211.

[0038] The scraper section 300 includes a scraper body 310 and connecting rods 320 connected to both ends of the scraper body 310. The scraper body 310 is located on the upper rear side of the material outlet of the paving trough 200. The scraper body 310 is arranged in a horizontally inclined manner. The scraper body 310 is used to directly level the poured material, ensuring a uniform and smooth thickness of the paved material, which is conducive to the subsequent vibration pressing operation. The connecting rod 320 is rotatably connected to both ends of the trough body 210. The trough body 210 is also provided with an adjustment member 330 for adjusting the downward pressure of the connecting rod 320. That is, by changing the downward pressure position of the connecting rod 320 by the adjustment member 330, the scraping height of the scraper body 310 can be changed, thereby achieving the control of the scraping height.

[0039] The connecting rod 320 includes a reinforcing rod 321 with one end fixedly connected to the scraper body 310 and a connecting shaft 322 pivotally mounted on the reinforcing rod 321. One end of the connecting shaft 322 is connected to the side of the trough body 210, allowing the reinforcing rod 321 to rotate due to its pivotal connection to the connecting shaft 322. A torsion spring 323 is mounted on the connecting shaft 322. One end of the torsion spring 323 is connected to the side of the trough body 210, and the other end of the torsion spring 323 is connected to the side of the reinforcing rod 321. The torsion spring 323 provides elastic force to restore the reinforcing rod 321 to its original position.

[0040] The other end of the reinforcing rod 321 is fixedly connected to a contact rod 324 for contacting an adjustment member 330. The adjustment member 330 comprises a threaded bracket 331 fixedly connected to the upper end surface of the trough body 210 and a long screw 332 threadedly mounted on the bracket 331. The lower end of the long screw 332 contacts the connecting rod 320. By rotating the long screw 332 to raise or lower it, the lower limit position of the scraper body 310 is adjusted to accommodate different scraping thicknesses.

[0041] By rotating the long screw 332, the long screw 332 moves up and down to adjust the degree to which the long screw 332 presses down on the contact rod 324. When the long screw 332 moves downward, it presses down on the contact rod 324, causing the scraper body 310 to tilt, thereby increasing the distance between the end of the scraper body 310 and the ground. When the long screw 332 moves upward, it does not press down on the contact rod 324. Under the action of the torsion spring 323, the reinforcement rod 321 rotates and returns to its original position, causing the scraper body 310 to fall, thereby decreasing the distance between the end of the scraper body 310 and the ground.

[0042] The vibrating plate section 400 includes a mounting frame 410 mounted on the paving trough 200 and a plate support member 420 mounted on the mounting frame 410. The mounting frame 410 is a rectangular frame fixed to the trough 210 by screws. The plate support member 420 is located behind the scraper section 300 and is used to press down the poured material. A driving member 430 is also mounted on the mounting frame 410 for driving the plate support member 420 in a reciprocating motion. The driving member 430 realizes the reciprocating motion of the plate support member 420.

[0043] The plate frame 420 includes a pressure plate body 421 and a column 422 fixedly connected to the upper end surface of the pressure plate body 421. The pressure plate body 421 is located behind the scraper portion 300 and is arranged horizontally to directly press down on the injected material. The column 422 is vertically plugged into the mounting frame 410 to provide guidance for the vertical movement of the pressure plate body 421. A connecting plate 423 is fixedly provided at the upper end of the column 422. A contact plate 424 for contacting the drive member 430 is provided on one side of the connecting plate 423. A return spring 425 is mounted on the column 422. The lower end of the return spring 425 is connected to the mounting frame 410, and the upper end of the return spring 425 is connected to the connecting plate 423.

[0044] The driving member 430 includes a second driving motor 431 installed on the mounting frame 410 and a pushing wheel 432 installed on the output end of the second driving motor 431. One end of the pushing wheel 432 is a flat end. When the pushing wheel 432 contacts the plate frame 420, the pushing wheel 432 forms a cam structure. The second driving motor 431 drives the pushing wheel 432 to rotate continuously. At the same time, the pushing wheel 432 continuously changes the supporting height, thereby driving the contact plate 424 and the pressure plate body 421 to rise and fall back and forth.

[0045] The second driving motor 431 drives the pushing wheel 432 to rotate. When the arc end of the pushing wheel 432 contacts the contact plate 424, the contact plate 424 is pushed up, so that the column 422 drives the pressure plate body 421 to move up. When the arc end of the pushing wheel 432 rotates past the contact plate 424, the contact plate 424 is no longer pushed up. The column 422 on the left and right of the return spring 425 drives the pressure plate body 421 to move downward. The pressure plate body 421 is moved up and down reciprocatingly, so that the pressure plate body 421 can vibrate the mortar and pour it into the gaps in the asphalt mixture.

[0046] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
