Embodiment 1

[0008] Embodiment 1, as shown in the figure, the potato harvester digging shovel comprises a shovel body (1), a connecting shaft (2) and a soil and potato dredging rod (3). The connecting shaft (2) of the excavating shovel is connected with the frame of the potato harvester, and along with the forward movement of the tractor, the soil furrow is raised, crushed and conveyed, and the soil and potato are sent to the separation mechanism through the soil and potato dredging column (3).

Embodiment 2

[0009] Example 2, as shown in the figure, the potato harvester digging shovel body (1) has a stepped cross-section. When the soil shovel passes through the shovel surface, the deformation of the soil shovel increases, making the shovel more crushable. The vertical distance from the tip of the shovel to the crushing conveying section (4) of the shovel body (1) should be less than the height of the soil compaction triangle formed by the common shovel with the length L as the base when the entry angle is 25°, which reduces the Working traction resistance of step shovel. The material of the lower surface of the stepped shovel shovel body (1) has higher hardness and wear resistance than the upper surface, so that the shovel has the function of self-sharpening and sharpening, and the soil penetration performance of the shovel is enhanced.

Abstract

The invention relates to a digging shovel used for a potato lifter, belonging to the technical field of agricultural machinery. The invention provides a ladder-shaped digging shovel, aiming at solving the problems that the traditional digging shovel has poor soil crumbling capability during operation, consumed traction force is high and the shovel is obtuse owning to abrasion of shovel point. The ladder-shaped digging shovel is mainly composed of a shovel body (1), a connecting shaft (2) and a soil potato dredging rod (3), the upper surface and the lower surface of the shovel body are formed by combining different materials, and hardness and abrasive resistance of the materials of the lower surface of the shovel body are required to be higher than those of the materials of the upper surface of the shovel body. The shovel body is divided into an interring section and a crumbling and conveying section according to function. An interring angle of the interring section is 25 degrees, which is relatively larger, the interring angle of the crumbling and conveying section of the shovel body is 13 degrees, and oblique angle of a shovel edge of a shovel point is 50-65 degrees. The shovel provided by the invention is applicable to soil which is seriously hardened and has the characteristics of small interring resistance, strong soil crumbling performance, smooth conveying, no blocking, autogenous grinding sharp function of the shovel point and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a stepped digging shovel used on a potato harvester. Background technique [0002] The task of the digging shovel is to drive the minimum amount of soil to excavate the potato ridge, and to loosen the soil as much as possible, to send the excavation to the separation device behind, and to require the least energy consumed when overcoming various resistances. During the working process of the digging shovel, the force on the soil is mainly divided into two stages: the compaction of the soil and the destruction of the soil. In this process, the wear of the tip of the shovel is serious, and the wear of the lower surface of the shovel tip is greater than that of the upper surface. . As the shovel tip wears, the shovel's penetration resistance also increases. Therefore, it is very difficult to accomplish this task or tasks related to it. [0003] The invention studies t...
