Therefore, in this embodiment, three soil crushing structures 510 are provided.

[0033] like Figure 2-7 As shown, in one embodiment, the farmland stone removal and crushing machine includes a frame 100, the front end of the frame 100 is connected to a traction device for towing the frame 100 forward, and the bottom of the frame 100 is provided with walking wheels so that the traction device can tow the frame 100 forward.

[0034] A screening component is provided at the rear side of the excavation component 200. A crushing component 400 is provided at the discharge end of the screening component, and the crushing component 400 is used to crush the first component. Specifically, the crushing component 400 is fixedly arranged on the frame 100. Preferably, the feed port of the crushing component 400 is provided with a cover plate for preventing stones and soil from splashing out of the feed port of the component during the process of crushing soil and stones. The screening component is used to screen out the first component in the material excavated by the excavation component 200 and convey the first component to the crushing component 400 for crushing, and the crushed first component falls back into the farmland.

[0035] Specifically, the screening assembly includes a first conveying mechanism 310 , a second conveying mechanism 320 , a third conveying mechanism 330 , and a fourth conveying mechanism 340 disposed at a first discharge end of the third conveying mechanism 330 .

[0036] The first conveying mechanism 310 is arranged on the frame 100 and is located at the rear side of the excavation assembly 200. The second conveying mechanism 320 is arranged on the frame 100 and is located at the discharge end of the first conveying mechanism 310. The third conveying mechanism 330 is arranged on the frame 100 and is located at the discharge end of the second conveying mechanism 320. The fourth conveying mechanism 340 is arranged on the frame 100 and is located at the discharge end of the third conveying mechanism 330. Specifically, in this embodiment, the third conveying mechanism 330 has a first discharge end located at the bottom and for the first component to flow out and a second discharge end located at the top and for the second component to flow out, and the fourth conveying mechanism 340 is arranged at the first discharge end of the third conveying mechanism 330. The discharge end of the fourth conveying mechanism 340 is provided with a stone crushing assembly 400.

[0037] The first conveying mechanism 310 is used to convey the material excavated by the excavation assembly 200 to the second driving mechanism from front to back. The second conveying mechanism 320 is used to convey the material conveyed by the first conveying mechanism 310 to the third conveying mechanism 330 from bottom to top. The third conveying mechanism 330 is used to convey the material conveyed by the second conveying mechanism 320 from bottom to top, and at the same time, during the conveying process, screen out the first component in the material and convey the first component to the fourth conveying mechanism 340. The fourth conveying mechanism 340 is used to convey the first component conveyed by the third conveying mechanism 330 from bottom to top to the stone crushing assembly 400 for crushing.

[0038] The so-called material includes mud, stone, and a mixture of all components excavated by the excavation assembly 200, such as plant stems, roots, stems, and leaves. The so-called first component refers to the component in the material that can roll downward along the conveying surface of the third conveying mechanism 330, including mud, soil, etc. The so-called second component includes the component in the material that cannot slide downward along the conveying surface of the third conveying mechanism 330, including plant stems, roots, stems, and leaves.

[0039] Specifically, the first conveying mechanism 310, the second conveying mechanism 320, the third conveying mechanism 330 and the fourth conveying mechanism 340 include a transmission belt 301, and the transmission belt 301 is provided with a plurality of transmission belts, and the plurality of transmission belts 301 are sequentially spaced along the width direction of the frame 100, and the transmission belt 301 can rotate under the drive of the driving device. A bearing rod 302 is provided on the transmission belt 301, and the bearing rod 302 is provided with a plurality of bearing rods, and the plurality of bearing rods 302 are sequentially spaced along the circumference of the transmission belt 301 and fixedly connected to the transmission belt 301. There is a gap between any two adjacent bearing rods 302 for the finer components in the material to flow out, and by leaving a gap between the two adjacent bearing rods 302, the finer components in the material are screened out, and the screened finer components eventually fall back into the farmland under the action of gravity. Among them, the so-called finer components refer to components that can pass through the gap between the two adjacent bearing rods 302, including fine soil, fine stone, etc.

[0040] The first conveying mechanism 310, the second conveying mechanism 320, the third conveying mechanism 330 and the fourth conveying mechanism 340 of this structure are not only simple in structure and reasonably designed, but also can separate finer components in the material, thereby reducing the burden of the crushing assembly 400 and increasing the service life of the crushing assembly 400.

[0041] Specifically, the second conveying mechanism 320, the third conveying mechanism 330 and the fourth conveying mechanism 340 also include a plurality of partition rods 303 arranged between any two adjacent supporting rods 302, and the plurality of partition rods 303 are arranged in sequence at intervals along the width direction of the supporting rods 302, and one end of the partition rod 303 is fixedly connected to one of the two adjacent supporting rods 302, and the other end extends in a direction close to the other of the two adjacent supporting rods 302.

[0042] The second conveying mechanism 320 , the third conveying mechanism 330 and the fourth conveying mechanism 340 in this structure divide the gap between two adjacent bearing rods 302 into smaller gaps by setting a dividing rod 303 , thereby effectively preventing mud, stones, etc. from being stuck between two adjacent bearing rods 302 .

[0043] Specifically, the second conveying mechanism 320 and the fourth conveying mechanism 340 further include baffles 304, and a plurality of baffles 304 are provided, and the plurality of baffles 304 are sequentially arranged at intervals along the circumference of the transmission belt 301 and fixedly connected to the transmission belt 301, and the baffles 304 are used to block the material, so that the second conveying mechanism 320 and the fourth conveying mechanism 340 can convey the material from bottom to top. Since the second conveying mechanism 320 and the fourth conveying mechanism 340 both convey the material from bottom to top, the baffles 304 are provided, so that the material on the second conveying mechanism 320 and the fourth conveying mechanism 340 cannot move downward along the conveying surface of the second conveying mechanism 320 and the fourth conveying mechanism 340, thereby achieving the purpose of enabling the second conveying mechanism 320 and the fourth conveying mechanism 340 to convey the material from bottom to top.

[0044] The second conveying mechanism 320 and the fourth conveying mechanism 340 of this structure are simple in structure and reasonably designed, and can effectively convey materials from bottom to top.

[0045] Specifically, the third conveying mechanism 330 also includes a shift rod 305, which is fixedly disposed on the load-bearing rod 302, and a plurality of shift rods 305 are disposed on one load-bearing rod 302, and the plurality of shift rods 305 are sequentially spaced apart along the length direction of the load-bearing rod 302 and fixedly connected to the load-bearing rod 302. The second component in the material is blocked by the shift rod 305 so that the second component cannot move downward along the conveying surface of the third conveying mechanism 330, while the first component can move downward along the conveying surface of the third conveying mechanism 330, thereby screening out the first component in the material. In the process of conveying the material, since the second component of the material (i.e., the plant stems and roots, stems and leaves) are intertwined, the stopper 305 is inserted into the gap of the second component, so that the second component of the material cannot move downward along the conveying surface of the third conveying mechanism 330 under the action of gravity, and since the first component of the material (i.e., mud and stones) is heavier, it can move downward along the conveying surface of the third conveying mechanism 330 under the action of gravity, and then fall to the fourth conveying component below, thereby achieving the purpose of separating the first component and the second component of the material. The first component of the material is conveyed to the crushing component 400 by the fourth conveying mechanism 340 for crushing, and then falls back to the farmland, while the second component is conveyed back to the farmland from the rear discharge end by the third conveying mechanism 330.

[0046] The third conveying mechanism 330 of this structure has a simple structure, a reasonable design, and is easy to operate, and can effectively separate the first component and the second component in the material.

[0047] In one embodiment, the farmland crusher also includes the high-efficiency soil crushing mechanism described in any of the above embodiments, which is used to crush the soil blocks excavated by the excavation component 200 so that the soil blocks will not be transported to the stone crushing component 400, thereby reducing the burden of the stone crushing component 400 and improving the crushing effect of the stone crushing component 400.

[0048] Specifically, the efficient soil crushing mechanism is arranged between the third conveying mechanism 330 and the fourth conveying mechanism 340. The mud blocks in the first component (i.e., mud blocks and stones) separated by the third conveying mechanism 330 fall downward under the action of gravity, and enter the efficient soil crushing mechanism in the process of falling. Under the action of the efficient soil crushing mechanism, the mud blocks are crushed. The crushed mud blocks fall back into the farmland through the gap of the supporting rod 302 of the fourth conveying mechanism 340. At the same time, the stones can also be preliminarily crushed to further reduce the burden of the stone crushing component 400 and improve the crushing effect and life of the stone crushing component 400.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
