Bionic viscosity/resistance reducing potato harvester digging shovel applicable to viscose heavy loam

Abstract

The invention discloses a bionic viscosity / resistance reducing potato harvester digging shovel applicable to viscose heavy loam, belonging to the technical field of agricultural machinery. With an integrated substrate structure, the digging shovel consists of fixing screw holes, an upper soil touch shoveling face, a convex face I, a concave face I, a shovel handle, a lower soil touch shoveling face, a convex face II and a concave face II, wherein the cross section of the substrate is of an arc structure; the convex arch face is the upper soil touch face of the digging shovel; and the concave face is the lower soil touch shovel face. The convex face I and the concave face I are uniformly distributed on the upper soil touch shovel face on the symmetry of the central axis; the convex face II and the concave face II are uniformly distributed on the lower soil touch shovel face on the symmetry of the central axis; the convex face I and the concave face I are in arc transition connection; and the convex face II and the concave face II are in arc transition connection; and two fixing screw holes are formed in the shovel handle. With novel structure and strong adaptability, the soil sticking ability of the potato digging shovel can be remarkably reduced, the soil entering and resistance reducing detachment performance is enhanced, and the viscosity / resistance reducing property is remarkably improved in comparison with traditional potato digging shovels.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a digging shovel for a bionic potato harvester with reduced viscosity and reduced resistance. Background technique [0002] The function of the potato digging shovel is to dig out the potato pieces and transport the potato pieces to the separation device. Digging performance is an important index to evaluate the performance of potato harvesting equipment, which is closely related to factors such as harvesting equipment structure, operating parameters, and key component materials. Northeast China is one of the main fields of potato planting in my country. Potato harvesters are an important guarantee for increasing the production and income of potato growers. However, the Northeast is mostly sticky and heavy loam. During the harvesting process, the phenomenon of potato digging shovel sticking to the soil is very prominent, seriously affecting the Benefits of potato h...

AI Technical Summary

Problems solved by technology

Northeast China is one of the home fields for potato planting in my country. Potato harvesters are an important guarantee for increasing the production and income of potato growers. However, the Northeast is mostly clay-heavy loam. During the harvest process, the phenomenon of potato digging shovel sticking to the soil is very prominent, seriously affecting the Benefits of Potato Harvesting in the Region

Compared with foreign potato harvesting machinery, domestic models cannot fully meet the needs of production development. There are three main problems: First, poor reliability

The soil environment of potato harvesting machinery is complex, and the efficiency of a single type of excavating mechanism is low, which cannot meet the basic requirements for use

Second, poor adaptability

Under different soil conditions and different plant conditions, the digging parts of potato harvesting machinery cannot effectively solve the problems of large digging resistance, serious soil adhesion, sand and gravel wear on the shovel surface, etc.

Third, insufficient power reserve

It is difficult to meet the power needs of digging and separating potatoes when working in fields with increased excavation depth and high soil specific resistance

[0003]The existing potato harvester digging shovel has a single form and a simple structure. When digging potato blocks, the clay phenomenon is serious, the resistance to entry into the soil is large, and the ability to break and break the soil is poor. Under the conditions of the terrain, there are problems such as poor adaptability and low reliability
