Abstract

The utility model relates to a multi-purpose ploughshare which is composed of a lateral wing 1 and a lateral wing 2. A front part is triangular, and a back part is dovetail-shaped. The bottom edge a1 of the ploughshare lateral wing 1 and the bottom edge a2 of the lateral wing 2 form an included angle alpha 1 which is ranged from 20 DEG to 120 DEG; the central line L of the ploughshare and the bottom edge a1 of the lateral wing 1 or the bottom edge a2 of the lateral wing 2 form an included angle alpha 2 which is ranged from 5 DEG to 70 DEG; the lateral wing 1 and the lateral wing 2 of the ploughshare form an included angle alpha 3 which is ranged from 60 DEG to 170 DEG. When the ploughshare is used for ploughing, resistance of earth is small, the ploughing can be flat and fast; the utility model can be used for harvesting underground rhizome crops, such as sweet potatoes, potatoes, etc., so that the underground rhizome of the crops can be turned over to the earth surface, and accordingly, picking up can be convenient.

Description

Multi-purpose digger

The utility model is the ploughshare that serves many purposes about a kind of.

The ploughshare of the existing plough of ploughing is because due to its structure, suffered soil resistance is big during the arable land, the ground of ploughing is not really flat, when being used to gather in the crops the underground rhizome crop, the underground rhizome of crop being turned over be embedded in the soil, also damage the underground rhizome of crop easily, therefore can not be used for the results of underground rhizome crop.

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can be when ploughing, suffered soil resistance is little, plough flatly and fast, and results underground rhizome crop for example when Ipomoea batatas, potato etc., can translate into the soil table to the underground rhizome of crop, be convenient to pick up, do not damage simultaneously a kind of multipurpose ploughshare of the underground rhizome of crop.

The purpose of this utility model realizes with following proposal:

This ploughshare is made up of flank 1 and flank 2, anterior one-tenth triangular shape, and the rear portion becomes dovetail shaped, the base a of ploughshare flank 1 ₁Base a with flank 2 ₂Angle be α ₁, its angle is preferably between 60 degree and 70 degree between 20 degree and 120 degree; The base a of ploughshare centre line L and flank 1 ₁Or the base a of flank 2 ₂Between angle be α ₂, its angle is preferably between 15 degree and 45 degree between 5 degree and 70 degree; Angle between ploughshare flank 1 and the flank 2 is α ₃, its angle is preferably between 100 degree and 130 degree between 60 degree and 170 degree.

This ploughshare can casting be an one, also can be welded with two symmetrical fully flanks.

This ploughshare is fixed on the plowshoe, plough body is fixed on the adjustable plow frame, when arable land or results underground rhizome crop,, reach the purpose of ploughing and gathering in the crops the underground rhizome crop of different spacings by adjusting adjustable plow frame.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is a vertical view of the present utility model.

Fig. 2 is the front view of the utility model ploughshare flank 1 or flank 2.

Fig. 3 is that A-A among the utility model Fig. 1 is to profile.

In the drawings, the 1st, flank 1,2nd, flank 2, a ₁Be the base of flank 1, a ₂It is the base of flank 2.

With reference to accompanying drawing, this ploughshare is made up of flank 1 and flank 2, anterior one-tenth triangular shape, and the rear portion becomes dovetail shaped, the base a of ploughshare flank 1 ₁Base a with flank 2 ₂Between angle be α ₁, its angle is 65 degree; The base a of ploughshare centre line L and flank 1 ₁Or the base a of flank 2 ₂Between angle be α ₂, its angle is 20 degree; Angle between ploughshare flank 1 and the flank 2 is α ₃, its angle is 116 degree.

In order to improve performance of the present utility model, the centre line L both sides are symmetry preferably.
