Description

A coulter for a farming machine

technical field

The utility model relates to the field of farming machines, in particular to a coulter used for farming machines.

Background technique

In agricultural production, dryland crops must be plowed in winter before sowing or transplanting. In order to be more conducive to crop growth, the general agronomic requirement is that the plowing depth should be more than 200mm, which is conducive to the growth of crop roots and soil moisture conservation. , To ensure the yield and quality of crops, this is the so-called deep plowing in agricultural production.

At present, my country's agricultural machinery only has plows and disc plows that are towed by high-horsepower four-wheel tractors to operate in plain areas. Part of the farmland in mountainous and hilly areas plowed by small-scale agricultural machinery has shallower and shallower plowing layers, underdeveloped root systems of crops, and poor drought and lodging resistance. Therefore, how to make the rotary tillage operation function driven by the walking tractor that is widely used in my country's agricultural production process reach the deep plowing operation requirement is the main purpose of this research invention.

The existing rotary tiller mounted on the walk-behind tractor generally has a radius of rotation of 210mm, deducting the radius of the transmission box of 90mm, and theoretically the maximum plowing depth can reach 120mm. Fracture, in general, the actual plowing depth is 100mm. That is to say, for the arable land in the vast mountainous and hilly areas, if the plowing radius of the coulter is simply increased or the plow plow and disc plow are used to achieve the purpose of deep plowing, the failure rate of the equipment will increase with the increase of plowing depth. Significantly improved, and most of the existing agricultural machines use arc coulters for the smoothness of cultivation, the stress effect is poor, and the coulters are easy to break when deep plowing.

Utility model content

The purpose of the utility model is to overcome the above-mentioned defects, and to provide a coulter suitable for deep plowing and used for agricultural machinery.

In order to solve the above technical problems, the technical solution adopted by the utility model is:

A coulter for an agricultural machine, comprising a mounting surface and a working surface connected to each other, the angle between the mounting surface and the working surface is 88-95°, the mounting hole is provided on the mounting surface, and the working surface A knife edge is arranged on the knife edge, and the setting track of the knife edge is bent toward the back of the knife.

Further, the shape of the blade is a broken line.

Further, the shape of the blade is arc-shaped.

Further, the edge angle of the coulter is 10°-30°.

Further, the bending angle of the blade is 150°-170°.

Further, the effective tillage width of the coulter is 130-250 mm.

The beneficial effect of the utility model is that: the angle between the coulter installation surface and the working surface is approximately right angle, and after the installation surface is installed on the coulter wheel, the working surface is parallel to the ground, so that the working surface can carry more weight while being used for farming. With more weight, the tiller can put more gravity load on the coulter to deepen the plowing depth. The blade is bent along the plane of the working surface to the side without the blade to reduce the contact area between the blade and the ground when it enters the soil. After the coulter enters the soil, as the depth of the blade increases, the soil width of the blade also gradually increases, which makes the plowing process of the coulter more stable and can adapt to greater tillage intensity and depth.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

The most critical idea of the utility model is that: the angle between the coulter mounting surface and the working surface is approximately right angle, so that the coulter can bear more load, and the blade is provided with bending, so that the coulter plowing process is more stable.

Please refer to Fig. 1 to Fig. 6, the coulter used for agricultural machinery in this embodiment includes a mounting surface 1 and a working surface 2 connected to each other, and the included angle between the mounting surface 1 and the working surface 2 is 88-95°. °, the installation surface 1 is provided with an installation hole 11, and the working surface 2 is provided with a blade 21, and the installation track of the blade 21 is curved toward the back of the blade.

The working process of the utility model is as follows: the coulters are evenly installed on the outer edge of the coulter wheel, the adjacent coulters are installed in reverse, and the coulter wheel is installed on the agricultural machine as a driving wheel, so that the main weight of the agricultural machine is pressed On the coulter wheel, a resistance device is added at the same time, and the driving wheel performs a semi-slip movement in the soil under the simultaneous action of the gravity and resistance of the agricultural machine, driving the agricultural machine forward and digging up the soil under the driving wheel, thereby deepening the plowing depth , the front and back of the blade are always on the same circumference, and the angle between the section line of the working surface and the cutting edge of the cutting edge and the tangent line of the turning circle of the cutting edge is kept consistent when the coulter is bent backward.

As can be seen from the above description, the beneficial effect of the utility model is that the angle between the coulter mounting surface 1 and the working surface 2 is approximately right angle, and the working surface 2 is parallel to the ground after the mounting surface 1 is installed on the coulter wheel, so that the working surface 2 While being used for farming, it can carry more weight. The farming machine can load more gravity on the coulters during farming to deepen the plowing depth. Bending reduces the contact area between the blade 21 and the ground when the blade 21 enters the soil. After the coulter enters the soil, as the depth of the blade 21 enters the soil increases, the width of the blade 21 eats soil gradually increases, making the plowing process more stable and adaptable to larger tillage intensity and depth.

Further, the shape of the bending part of the blade 21 is a broken line.

It can be seen from the above description that the shape of the bending part of the blade 21 is a broken line, and the width of the blade 21 for eating soil increases linearly when entering the soil, and the force of the coulter wheel changes little.
