Abstract

The utility model discloses an adopt universal ball structure to prevent the impaired plough of plough sword, the technical field that belongs to is agricultural machinery and apparatus, and the technical problem who plans to solve is that the plough meets too big barriers of resistance such as stone and damages when farming. The plough is used for breaking soil blocks and ploughing out grooves by various driving means, which is an indispensable step before farming and seeding, but the plough blades are always damaged by collision in the ploughing process. The utility model provides a connection structure of universal ball for protecting coulter from damage. The plough body is fixed on the ball of the universal ball and then fixed on the support frame of the plough through the shell of the universal ball. The load of the universal ball structure is adjusted according to the condition and specific resistance of the cultivated soil, and the plowing effect is ensured. When the coulter collides with an obstacle with too large resistance such as a stone and the like and the resistance exceeds the bearing load of the universal ball structure, the universal ball rotates after being stressed to drive the plough body and the plough head to change directions and avoid the obstacle, so that the plough edge and the plough body are effectively protected.

Description

Plough with universal ball structure for preventing plough edge from being damaged

Technical Field

Agricultural machinery and appliances.

Background

Plows are the most commonly used agricultural implements, but when plows are used to loosen agricultural fields, the plow tips sometimes touch rocks, causing damage to the plow. The plough is also used for damaging the plough when the plough is used for deep ploughing of grass roots, tree roots, a large amount of small stones, a large amount of broken stones, bricks, hardened soil and dry and hard soil. When reclaiming wasteland, the plow can also touch tiles, coffin plates, rotten clothes and the like. All this causes damage to the plow, particularly the plow tip. In addition, the contact friction resistance of the plough share and the soil is large, so that the problems of labor waste, time waste and low speed caused by animal power pulling are solved, or the mechanical traction consumes much oil and wastes energy; can cause premature wear and even bending of the plow. Furthermore, even if the plow is not damaged, it may happen that the plow pulls the hard object forward, causing a sudden increase in resistance.

Therefore, how to prevent the plough from being damaged after collision with the stone is always the focus of the continuous efforts of the agricultural scientists, utility models and patent inventors, such as: the plough tip has chisel shape, arrow shape, double wing shape, etc. to reduce the resistance of the plough to soil cutting and tillage.

SUMMERY OF THE UTILITY MODEL

The utility model provides an adopt universal ball structure to prevent the impaired plough of coulter, when the coulter was excessively atress, the rotation through universal ball changed the direction of coulter, can protect the plough effectively, avoided damaging.

The problems to be solved are as follows: when the plough is used for tillage, the plough is damaged by the obstacle with too large resistance, such as stone blocks and the like.

The technical scheme is as follows: the coulter is connected to the fixed support of the coulter by adopting a universal ball structure, and then cultivation is carried out by various driving modes. When the coulter is subjected to larger resistance, the universal ball can turn to any direction, and certainly mainly turns to the direction with small stress to avoid hard objects, so that the damage of the plough blade and even the whole coulter is avoided.

Has the advantages that: the damage of the plough after colliding with a large-resistance obstacle during cultivation is reduced.
