Abstract

The utility model relates to the field of agricultural engineering and machine repair, in particular to the design, manufacture, restoration and hardening of plowshares. The technical result of the utility model is to reduce the wear rate of the bow part (bit) of the share by reducing the resistance of the tip with the soil and improving the quality of the soil treatment. The technical result is achieved due to the fact that the generators of the working surface of the tip have the shape of a cycloid with a radius of the rolling wheel R = 0.2 m, while the tip is larger than half the share width. The share design can be trapezoidal or chisel-shaped with mounting holes 6. The symmetrical shape of the tip with mounting holes allows you to change its position as the nose of the tip is worn (rotate 180 °). consists of the main 3, nose 5 and blade 4 parts. Tip 1 is attached to the bow of the share, at an angle α = 25-30 ° to the horizon with bolts 2 with countersunk head. The ploughshare is attached to the shoe of the plow body using plow bolts 6.

Description

The utility model relates to the field of agricultural engineering and machine repair, in particular to the design, manufacture, restoration and hardening of plowshares.

Known strip trapezoidal share for dump plowing [patent for the invention of the Russian Federation No. 2125507, class. B23P 6/00, 1997], the construction of which comprises a concave toe made of carbon steel deposited on a ploughshare.

The design shortcomings include the complexity of surfacing the sock by heating with high-frequency currents to a temperature of 900 °, as well as the high likelihood of radial wear in the ploughshare located above the sock

The prototype is a plow share plow for dump plowing [patent for utility model No. 81619 (bunny No. 2008145238), А01В 15/00, 2008].

The design of such a share consists of the main, blade and nose parts, where a tip made of wear-resistant material is installed in the nose of the share, which, in turn, consists of a cone-shaped element and a fixing fork. The disadvantages of the design include: relatively high resistance to the movement of the soil particles due to the large area of the cone; there is a chance of the fork engaging from the side wall of the furrow, which adversely affects the quality of the plow.

The technical result of the utility model is to reduce the wear rate of the bow (bit) of the share by reducing the resistance of the tip with the soil and improving the quality of the soil treatment.

The technical result is achieved due to the fact that the generators of the working surface of the tip have the shape of a cycloid with a radius of the rolling wheel R = 0.2 m, while the length of the tip is more than half the width of the share.

The share design can be trapezoidal or chisel-shaped with mounting holes.

The symmetrical shape of the tip with mounting holes allows you to change its position as you wear the nose of the tip (rotate 180 °).

The design of the share, and especially its bow, is associated with optimization of parameters and reduction of wear of the working surface.

Theoretical and experimental studies show that the wear of working surfaces when abrasive particles move along them depends on the speed V and the specific pressure N:

And = nNV ^k ,

where And - wear;

n is the coefficient of proportionality;

N is the specific pressure;

V is the velocity of the abrasive particle;

k is an exponent.

It is also known that when the bodies move along convex surfaces, a decrease in their speed is observed, which means that surface wear is reduced.

This constructive solution provides a decrease in the wear rate of the bow part (chisel) of the share, as well as the elimination of the appearance of lucid wear in the area of the share of the share.

The essence of the utility model is to reduce wear on the bow surface, reduce energy consumption for tillage, and avoid the formation of lucid wear, as illustrated by the drawings, where in FIG. 1 shows a design diagram of the proposed share, in FIG. 2 shows a top view and a cross section of the tip.

The ploughshare of the plow body of increased strength and wear resistance consists of the main 3, bow 5 and blade 4 parts. Tip 1 is attached to the bow of the share, at an angle α = 25-30 ° to the horizon with bolts 2 with countersunk head. The ploughshare is attached to the shoe of the plow body using plow bolts 6.

The objective of the proposed ploughshare design is to increase its service life. This is achieved by screw fastening to the nose of the share share of the tip made of a material of increased hardness having the shape of a conical body.

Since in other technical solutions the totality of the distinguishing features of the utility model is not found, then it meets the criterion of "novelty."
