Abstract

The utility model relates to a new -type share plough plough body curved surface, this plough body curved surface are pseudo - spherical shape, and the share of plough body curved surface, plow breast, mouldboard kicker are the patch that a slice is complete, have the characteristics of cutting a hole ploughshare, protruding chest and plunderring the wing, and share, breast are separately made, are convenient for restore and change resources are saved. The utility model discloses the pseudo - sphere that the initiative gaussian curvature of adoption is the burden constant curvature is as the plough body curved surface, the burden constant curvature does: K= - 11600 for the plough body curved surface has better fairness than other plough body curved surfaces, and its plough body curved surface can play better and dig, the effect of hack, has reduced farming resistance and energy consumption, solved present share plough plough body curved surface gaussian curvature can't highly concentrate as same camber, farming resistance and energy consumption is great, the big problem of plough body curved surface clay nature, and simple structure can accurately make, easily uses widely.

Description

New-type Plough Surface

Technical field

This utility model relates to agricultural arable land field of mechanical technique, is specifically related to a kind of new-type Plough Surface.

Background technology

Arable land is operation most basic in agricultural tillage system, its purpose is to chesson, covers weeds, anti-disease pest Do harm to, create favourable condition for crop growthing development.Conventional primary tillage equipment has mouldboard plow, disc plough, combined plough with rotary tiller, rotary tillage Machine, subsoiling plow etc., primary tillage equipment with the longest history during wherein mouldboard plow is agricultural production, quantity is most, most widely used, ploughshare formula During ploughing is made, upturned soil carries out broken upset along the warping surface of plow bottom, completes to ravel soil and overturn, reaches the purpose of soil cultivation. Owing to the power of plough body is acted predominantly in the warping surface of plow bottom by upturned soil, the shape of the warping surface of plow bottom and parameter directly affects plough body farming Quality, resistance and energy expenditure, so the warping surface of plow bottom be mouldboard plow design core.The ploughshare formula that traditional method for designing is formed Plough warping surface of plow bottom Gaussian curvature is highly concentrated near same curvature value, it is impossible to making warping surface of plow bottom each point Gaussian curvature is same song Rate value so that warping surface of plow bottom fairness is poor, causes the warping surface of plow bottom of poor quality, tradition plough body clay under clayed soil tillage condition Property serious, dig, hack performance weak, tillage resistance is big, and efficiency is low, increases energy expenditure, and tradition plough body cannot reach on manufacturing To accurately manufacturing so that warping surface of plow bottom quality is uneven, so developing one to dig that hack performance is good, tillage resistance Little, adhesive attraction is little, fairness good, manufacture is easy and the Plough Surface that can accurately manufacture is desirability.

Utility model content

The purpose of this utility model is to provide a kind of new-type Plough Surface, for pseudosphere shape, described puppet Sphere parameters equation is:

。

This utility model Plough Surface is pseudosphere shape, and the warping surface of plow bottom is a negative surface of constant curvature, described negative Constant curvature value is: K=1/1600, and warping surface of plow bottom fairness is good, and during farming, earth adhesiveness is little.

This utility model Plough Surface is pseudosphere shape, has chisel ploughshare, convex breast, plunders the feature of the wing, makes plough body Curved surface buries rapidly, and hack of digging is effective, and upturned soil is little to the active force of plough body, decreases tillage resistance and energy expenditure.

The ploughshare of this utility model Plough Surface, plow breast, mouldboard kicker are a piece of complete patch, manufacture easy and Can accurately manufacture.

The ploughshare of this utility model Plough Surface, mouldboard are separately manufactured, and ploughshare is the fastest part that weares and teares, separately Manufacture, it is simple to repair and change, economize on resources.

Accompanying drawing explanation

Fig. 1, Fig. 2 and Fig. 3 are respectively pseudo-spherical front view, left view and top view.

Fig. 4 and Fig. 5 is the structural representation of new-type Plough Surface.

In figure: 1 ploughshare, 2 mouldboards, 3 plow breasts, 4 mouldboard kickers, 5 boost lines.

Detailed description of the invention

Referring to the drawings 1～5, new-type Plough Surface is pseudosphere shape, including ploughshare 1, plow breast 3, mouldboard kicker 4.

Its new-type Plough Surface is pseudosphere shape, and described pseudo-spherical parametric equation is:

。

Its new-type Plough Surface is with pseudosphere inner surface for warping surface of plow bottom work surface, and type B error sphere is a bit Share beak, crosses the warping surface of plow bottom that the warp of this point is constituted by ploughshare blade line.

The ploughshare 1 of its Plough Surface, plow breast 3, mouldboard kicker 4 are a piece of complete patch, ploughshare 1, mouldboard 2 are entered Row is separately manufactured.

This utility model Plough Surface is negative surface of constant curvature, described negative constant curvature be: K=1/1600.

This utility model Plough Surface has chisel ploughshare, convex breast, plunders the feature of the wing.

This utility model Plough Surface can be connected soil by bolt with other parts of main plough body Farming.
