[0022] As shown in the figure, U-shaped frame 12 is installed at the front of tractor 1, specifically the middle part of U-shaped frame 12 is installed on the frame body at the bottom of tractor 1, and U-shaped frame 12 is fastened with the frame body by bolt. Figure 1 Each U-shaped wheel frame 19 is provided with steering wheel 10 inside, and the mounting shaft 20 at the center of steering wheel 10 is rotatably connected with the bottom of U-shaped wheel frame 19;

[0023] U-shaped wheel frame 19 is vertically installed with support shaft 24 at the top, and the top of support shaft 24 is rotatably installed in support 8, support 8 is at least two, so that support shaft 24 can be firmly supported, and support 8 is fixed on the side surface of L-shaped support arm 7.

[0024] It should be noted that, since the process of fertilization needs to travel on the lawn or ground, the U-shaped wheel frame 19 needs to be designed large enough, and the gap between the U-shaped wheel frame 19 and the steering wheel 10 needs to be large enough to avoid the steering wheel 10 adhering to the sludge being stuck by the U-shaped wheel frame 19, which is the reason why the L-shaped support arm 7 is installed at the end of the U-shaped frame 12, and the L-shaped support arm 7 can increase the height of the support 8 from the ground, so that the support 8 has a larger installation space below. The steering wheel 10 includes a hub and a tire, and the mounting shaft 20 is installed at the center of the hub.

[0025] As shown in Figure 2 and Figure 5 , the two L-shaped support arms 7 are connected by the connecting beam 17 away from one end of the tractor 1, which can increase the strength between the two connecting beams. The middle of the connecting beam 17 is provided with a fixing seat 22, as shown in Figure 3 , an inclined upward driving shaft 21 is rotatably installed in the fixing seat 22, and the top of the driving shaft 21 is coaxially connected with the spreading disc 6, so that the spreading disc 6 is inclined together with the driving shaft. The driving shaft 21 is provided below the driving motor 18, and the driving motor 18 is fixed below the connecting beam 17 through the motor frame. The driving motor 18 drives the spreading disc 6 to rotate quickly.

[0026] A material box 2 is arranged in the U-shaped frame 12, and the material box 2 is connected with the U-shaped frame 12 through bolts, so that the material box is convenient to disassemble. The side of the material box 2 close to the spreading disc 6 is provided with a spiral lifting cylinder 4, and the inlet 9 below the spiral lifting cylinder 4 is communicated with the bottom of the material box 2. The outlet 15 of the spiral lifting cylinder 4 is arranged above the spreading disc 6;

[0027] In order to avoid the spiral lifting cylinder 4 occupying more space, as shown in Figure 1 , the side of the material box 2 close to the spreading disc 6 is an inclined upward slope, and the installation cavity 14 extending outwards towards the tractor 1 is arranged on the slope.

[0032] The operator can turn the steering by controlling the clutch handle on the two handles of the tractor, when the tractor turns, the universal wheel plays an important role at this time, because when the tractor 1 turns, one wheel does not move or the rotating speed is reduced, and the other wheel continuously rotates, and the steering is realized through the speed difference, and because of the flexibility of the universal wheel, the tractor 1 can turn together with the wheels when turning.

[0033] The side of the spreading disc 6 close to the spiral lifting cylinder 4 is provided with an arc-shaped surrounding plate 5, the arc-shaped surrounding plate 5 is in gap cooperation with the edge of the spreading disc 6, the arc-shaped surrounding plate 5 is installed on the discharge port 15, the two sides of the arc-shaped surrounding plate 5 are connected with the spiral lifting cylinder 4 through the fixing frame 13, the arc-shaped surrounding plate 5 is not more than half of the side of the spreading disc 6, the part of the arc-shaped surrounding plate 5 above the spreading disc 6 is high enough, the arc-shaped surrounding plate 5 can block the fertilizer from being thrown to the operator from above the spreading disc 6, and the arc-shaped surrounding plate 5 can block the fertilizer from splashing.
