It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] like Figure 1 , Figure 2The peanut digger shown includes a frame 1, and wheels are arranged at the bottom of the frame 1. A front shovel 2 is installed at the front end of the frame 1 for digging soil to dig out all the peanut vegetation in the soil; a conveyor belt 3 is arranged in the middle of the frame 1, and the conveyor belt 3 is continuously raised from the front to the back, and the front shovel 2 produces peanuts in the soil, and the peanuts enter the conveyor belt 3 and are raised; a turntable assembly is arranged below the rear end of the conveyor belt 3, which is driven to rotate by the shaft, and the peanuts fall freely from the rear end of the conveyor belt 3. After contacting the turntable assembly, the peanut vegetation is gathered and falls to the ground in a shape with the roots facing upward. A driving assembly is also arranged on the frame 1 to drive the conveyor belt 3 and the turntable to operate.

[0033] Specifically, the turntable assembly includes a rotating shaft, on which a plurality of toothed turntables 4 are sleeved, and the toothed turntables 4 are used to sweep the soil on the rhizomes of peanuts. Preferably, the rotating shaft is provided with two symmetrical groups, and the rotating shaft is arranged downwardly from the outer side of the frame 1 to the middle. The two groups of rotating shafts make the two corresponding groups of toothed turntables 4 form a V-shaped opening, and when the peanut rhizomes fall, they will contact the toothed turntables 4 and gather toward the middle. In order to prevent the excavator from speeding too fast, causing the peanut vegetation to pass over the turntable assembly and be thrown off, baffles 14 are formed on both sides of the rear end of the conveyor belt 3, and the baffles 14 are retracted toward the middle.

[0034] In one embodiment, the diameter of the toothed turntable 4 gradually decreases from both sides of the rotating shaft to the middle. A guide tube 5 is provided between the toothed turntables 4 of each set of rotating shafts. The guide tube 5 guides the peanut rhizomes to fall from the rear side of the toothed turntable 4 and fall from the gap between the two sets of guide tubes 5. Multiple guide tubes 5 extend to the rear of the frame 1, and the guide tubes 5 corresponding to the two sets of rotating shafts also form two inclined surfaces to guide the peanut vegetation to slide toward the gap in the middle. The guide tubes 5 located on each side of the rotating shaft have a larger diameter of the toothed turntables 4 at both ends and a smaller diameter of the toothed turntable 4 in the middle. The toothed turntable 4 can also drive the peanut vegetation to approach the guide tube 5 in the middle. From this position, the peanut vegetation sliding toward the gap is guided down by the heavier stems and leaves, so that the roots of the peanuts fall relatively upward to the ground.

[0035] Specifically, the front shovel 2 includes a left shovel and a right shovel of symmetrical structure, the left shovel and the right shovel form a V-shape opening to the front end of the frame 1, the left shovel and the right shovel are provided with guide bars 6, the guide bars 6 extend to the edge of the transmission belt, and the V-shaped structure mainly plays a gathering role. Peanut openers 13 are provided on both sides of the front end of the frame 1 for cutting off the underground extended rhizomes of peanuts.

[0036] The driving assembly includes a driving motor 7, a transmission shaft 8, a belt 10 and a belt 10 wheel 9. The belt 10 wheel 9 is arranged at both ends of the transmission shaft 8. The driving motor 7 also includes a transmission. The driving motor 7 drives the transmission shaft 8 to rotate, and the belt 10 drives the conveyor belt 3 and the turntable assembly to rotate respectively. This is well known to those skilled in the art and will not be elaborated here.

[0037] The vehicle frame 1 is provided with a gantry 11 extending toward the front end, and the gantry 11 is connected with a connecting plate 12, which can be connected to a front traction vehicle, such as a tractor, through the connecting plate 12, thereby improving the applicability of the product.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
