The main frame 3 is arranged above the bottom plate 1, the main frame 3 comprises a main frame and a balance frame, the hopper 4 is arranged on the main frame 3, the running wheel 2 is arranged at the bottom of the bottom plate 1, the guide pipe 11 is arranged at the bottom of the hopper 4, and the guide pipe 11 comprises a vertical pipe, a corner pipe and an oblique pipe from top to bottom. A slot is provided on the side of the vertical tube, and the flow regulating plate 5 is inserted from the slot to adjust the falling material flow by pulling and pulling. The corner connects the vertical tube and the oblique tube. The outlet end of the oblique tube is arranged on the right side of the bottom plate 1. The sieve plate 10 is arranged in the hopper 4. The sieve plate 10 is provided with a plurality of sieve holes. The limiter 7 includes a longitudinal limit plate 72 and a transverse limit plate 71, which are fixed to the right side of the main frame 3 by a clamp 8. The outlet of the oblique tube is just above the space formed by the longitudinal limit plate 72 and the transverse limit plate 71.

[0022] Furthermore, the front sides of the longitudinal limit plate 72 and the transverse limit plate 71 are provided with scales, and the back sides are fixedly welded with fixing rods 9, which are used to strengthen the strength of the limiter to prevent displacement during movement.

[0023] Furthermore, the main frame includes four longitudinal main rods and two transverse main rods, the balancing frame includes two transverse rods and a longitudinal rod, which are fixed in the middle of the longitudinal main rods to form a quadrilateral structure, the longitudinal main rods are vertically welded to the bottom plate to form a quadrilateral frame structure, the transverse main rods are arranged on the left and right sides of the frame structure, and the hopper 4 is placed thereon, and the two transverse main rods just limit its position.

[0024] Furthermore, the number of the running wheels 2 is three, one is arranged at the front end of the base plate 1, and two are symmetrically arranged at the rear end, forming an equilateral triangle with the running wheels at the front end. The triangle has strong stability and is easy to maintain balance.

[0025] Furthermore, it also includes an auxiliary power connection ring 6, which is arranged in the middle of the front end transverse rod of the balance frame, and the auxiliary power connection ring 6 is connected to the loading vehicle.

[0026] Furthermore, handles 12 are provided on both sides of the rear end of the main frame 3. The handles 12 are rectangular and are welded and fixed to the longitudinal main rod to facilitate control of the adjustment direction.

[0027] Furthermore, the clamping member 8 includes a first card body 81, a second card body 82, and a pin shaft 83. The clamping member 8 is fixedly welded to the limiter 7 as a whole. The first card body 81 and one end of the second card body 82 are rotatably connected through the pin shaft 83. The other end of the first card body 81 is fixedly connected with a buckle 84.

The buckle 84 is clamped in the slot 85 so that the clamping member 8 forms a ring structure, which can fix the limiter 7 on the main frame 3.

[0028] The use process of the present invention is as follows: after determining the thickness and height of the paving layer, the limiter 7 is fixed on the main frame 3. For example, when the thickness and width are both 40 cm, a transverse limiter 71 with a scale length of 40 is set as needed, and the longitudinal limiter 72 is fixed first. The transverse limiter 71 is adjusted from bottom to top to 40 according to the scale on the longitudinal limiter 72 to ensure the width and thickness. The transverse limiter 71 and the longitudinal limiter 72 are arranged perpendicular to each other, and the limiter 7 is arranged below the oblique pipe outlet of the drainage pipe 11. The limiter 7 is selected according to the needs. The sieve plate 10 with sieve holes of corresponding sizes is placed in the hopper 4, and the entire device is connected to the loading vehicle (truck, tricycle, etc.) through the auxiliary power connecting ring 6. The loading vehicle unloads the crushed stone into the hopper 4. After the crushed stone is screened by the sieve plate 10, it is led to the road surface to be paved through the drainage pipe 11. The limiter 7 limits the width and thickness. As the loading vehicle pulls the device forward, the roadbed is paved. During the paving process, the flow regulating plate 5 can be pulled out and pulled to adjust the falling flow of the crushed stone as needed, and the operator controls the adjustment direction through the handle at the back of the device.
