[0034] As Figures 1-6 shown, the present utility model provides a farmland stone removing and crushing machine, which includes a frame 100. The front end of the frame 100 is connected to a traction device for pulling the frame 100 forward. Traveling wheels are arranged at the bottom of the frame 100 to facilitate the traction device to pull the frame 100 forward. A digging assembly 200 for digging soil and / or stones is arranged at the front end of the frame 100. Specifically, the digging assembly 200 includes a plurality of digging shovels 210 arranged at intervals in sequence along the width direction of the frame 100.

[0035] A screening assembly is arranged at the rear side of the digging assembly 200. A crushing assembly 400 is arranged at the discharge end of the screening assembly. The crushing assembly 400 is used for crushing the first component. Specifically, the crushing assembly 400 is fixedly arranged on the frame 100. Preferably, a cover plate is arranged at the feed inlet of the crushing assembly 400 to prevent stones and soil blocks from splashing out from the feed inlet of the assembly during the process of crushing soil blocks and stones. The screening assembly is used for screening out the first component from the materials dug out by the digging assembly 200 and conveying the first component to the crushing assembly 400 for crushing. The crushed first component then falls back into the farmland.

[0036] 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 arranged at the first discharge end of the third conveying mechanism 330.

[0037] Among them, the first conveying mechanism 310 is arranged on the frame 100 and is located at the rear side of the digging 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 below for the first component to flow out and a second discharge end located above for the second component to flow out. The fourth conveying mechanism 340 is arranged at the first discharge end of the third conveying mechanism 330. The crushing assembly 400 is arranged at the discharge end of the fourth conveying mechanism 340.

[0038] The first conveying mechanism 310 is used to convey the materials excavated by the excavation assembly 200 from front to back to the second conveying mechanism 320. The second conveying mechanism 320 is used to convey the materials conveyed by the first conveying mechanism 310 from bottom to top to the third conveying mechanism 330. The third conveying mechanism 330 is used to convey the materials conveyed by the second conveying mechanism 320 from bottom to top. At the same time, during the conveying process, the first component in the materials is screened out and conveyed 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 crushing assembly 400 for crushing.

[0039] Among them, the so-called materials include a mixture composed of all components excavated by the excavation assembly 200, such as mud blocks, stone blocks, plant plants, and the roots, stems, and leaves of plants. The so-called first component refers to the components in the materials that can roll downward along the conveying surface of the third conveying mechanism 330, including mud blocks, soil blocks, etc. The so-called second component includes the components in the materials that cannot slide downward along the conveying surface of the third conveying mechanism 330, including plant plants and the roots, stems, and leaves of plants.

[0040] Specifically, the first conveying mechanism 310, the second conveying mechanism 320, the third conveying mechanism 330, and the fourth conveying mechanism 340 include conveyor belts 301. There are multiple conveyor belts 301. The multiple conveyor belts 301 are arranged at intervals in sequence along the width direction of the frame 100, and the conveyor belts 301 can rotate under the drive of the driving device. There are multiple load-bearing rods 302 arranged on the conveyor belt 301. The multiple load-bearing rods 302 are arranged at intervals in sequence along the circumferential direction of the conveyor belt 301 and are fixedly connected to the conveyor belt 301. There is a gap between any two adjacent load-bearing rods 302 for the finer components in the materials to flow out. By leaving a gap between the two adjacent load-bearing rods 302, the finer components in the materials are screened out. The screened finer components finally fall back to the farmland under the action of gravity. Among them, the so-called finer components refer to the components that can pass through the gap between the two adjacent load-bearing rods 302, including fine soil, fine stones, etc.

[0041] The first conveying mechanism 310, the second conveying mechanism 320, the third conveying mechanism 330, and the fourth conveying mechanism 340 with this structure are not only simple in structure and reasonable in design, but also can separate the finer components in the materials, thereby reducing the burden on the crushing assembly 400 and improving the service life of the crushing assembly 400.

[0042] Specifically, the second conveying mechanism 320, the third conveying mechanism 330, and the fourth conveying mechanism 340 further include a plurality of partition rods 303 disposed between any two adjacent carrier rods 302. The plurality of partition rods 303 are sequentially arranged at intervals along the width direction of the carrier rod 302. One end of the partition rod 303 is fixedly connected to one of the two adjacent carrier rods 302, and the other end extends toward the direction close to the other of the two adjacent carrier rods 302.

[0043] In the second conveying mechanism 320, the third conveying mechanism 330, and the fourth conveying mechanism 340 of this structure, by providing the partition rods 303, the gap between two adjacent carrier rods 302 is divided into smaller gaps, thereby effectively preventing mud blocks, stones, etc. from getting stuck between two adjacent carrier rods 302.

[0044] Specifically, the second conveying mechanism 320 and the fourth conveying mechanism 340 further include baffles 304. A plurality of baffles 304 are provided. The plurality of baffles 304 are sequentially arranged at intervals along the circumferential direction of the conveyor belt 301 and are fixedly connected to the conveyor belt 301. The material is blocked by the baffles 304 so that the second conveying mechanism 320 and the fourth conveying mechanism 340 can convey the material from bottom to top. Since both the second conveying mechanism 320 and the fourth conveying mechanism 340 convey the material from bottom to top, by providing the baffles 304, the material on the second conveying mechanism 320 and the fourth conveying mechanism 340 cannot move downward along the conveying surfaces of the second conveying mechanism 320 and the fourth conveying mechanism 340, thereby achieving the purpose that the second conveying mechanism 320 and the fourth conveying mechanism 340 can convey the material from bottom to top.

[0045] The second conveying mechanism 320 and the fourth conveying mechanism 340 of this structure are simple in structure, reasonable in design, and can effectively convey the material from bottom to top.

[0046] Specifically, the third conveying mechanism 330 further includes a baffle 305. The baffle 305 is fixedly arranged on the bearing rod 302, and a plurality of baffles 305 are arranged on one bearing rod 302. The plurality of baffles 305 are arranged at intervals in sequence along the length direction of the bearing rod 302 and are fixedly connected to the bearing rod 302. The second component in the material is blocked by the baffle 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. During the conveying of the material, since the second components in the material (i.e., the plants, roots, stems and leaves of plants) are intertwined, the baffle 305 is inserted into the gaps of the second components, so that the second components in the material cannot move downward along the conveying surface of the third conveying mechanism 330 under the action of gravity. Since the first components in the material (i.e., mud blocks and stone blocks) are heavier, under the action of gravity, they can move downward along the conveying surface of the third conveying mechanism 330, and then fall onto the fourth conveying component below, thereby achieving the purpose of separating the first component and the second component of the material. The first component in the material is conveyed by the fourth conveying mechanism 340 to the crushing component 400 for crushing, and then falls back into the farmland, while the second component is sent back to the farmland from the rear discharge end by the third conveying mechanism 330.

[0047] The third conveying mechanism 330 with this structure is simple in structure, reasonable in design, convenient in operation, and can effectively separate the first component and the second component in the material.

However, it is understood that the embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures and technologies have not been shown in detail so as not to obscure the understanding of this description.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
