Peanut crushed soil seedling device

Abstract

The invention provides an extensible tooth type soil pulverizing and seedling shifting device for peanuts. The soil pulverizing and seedling shifting device comprises a roller, a rotating main shaft, extensible teeth, a roller fixing disk, an extensible tooth fixed device and an extensible tooth moving device; the roller fixing disk, the extensible tooth fixed device and the extensible tooth moving device penetrate the rotating main shaft; the rotating main shaft is arranged in the center of the roller and connected with a power device through a driving chain wheel; the surface of the roller is provided with through holes; one end of every extensible tooth is arranged inside the roller and the other end of the extensible tooth is arranged outside the roller through the corresponding through hole; the periphery of the roller fixing disk is fixedly connected with the roller through bolts. The extensible tooth type soil pulverizing and seedling shifting device for peanuts is arranged at the front end of a conveyor device and accordingly clods after crop digging can be broken and accordingly the clods can be refined, the clods in the conveying process can be reduced, and the blocking of a fruit picking device is prevented; meanwhile the cleaning is convenient and the soil containing rate after harvest is reduced; peanut seedlings are directly shifted to a rear sliding plate after the soil pulverizing is achieved so as to fall onto the conveyor device and accordingly the width of the conveyor device is reduced.

Description

technical field [0001] The invention relates to a part of an agricultural machine, in particular to a seedling pulling device, in particular to a soil crushing seedling pulling device for a peanut combine harvester. Background technique [0002] Peanut is an important economic crop with a wide range of planting areas. In recent years, with the continuous increase of peanut planting area and the large transfer of rural labor force, the labor force in the busy season of "three autumns" is obviously insufficient. In addition, the labor intensity of peanut harvesting is high and the harvesting time is long, which affects the subsequent operations. Therefore, the mechanization of peanut harvesting has become the main research content of peanut production. The peanut combine harvester has multiple functions such as digging, conveying, fruit picking, cleaning and fruit collection. It is suitable for large-scale plots and has the characteristics of high production efficiency and lo...

AI Technical Summary

Problems solved by technology

[0003] (1) After the peanuts are dug out, a large amount of soil is also dug out. The conveying device transports the soil to the fruit picking device, which will easily lead to congestion of the fruit picking device, and increase the power of the subsequent cleaning device;

[0004] (2) Since the bulk soil is relatively solid, it is also difficult to leak it through the mesh opening during the transportation process, and it cannot be removed by the cleaning device, which eventually results in a higher soil content of the harvested peanuts;

[0005] (3) Since the excavating and conveying device of the traditional peanut combine harvester is integrated and lacks the reversing device for turning seedlings, the overall machine tool is bulky, and the operation flexibility and operability are poor
