Description

A sawtooth disc opener with a guillotine for no-till sowing of grain

technical field

The utility model relates to the technical field of agricultural tools, in particular to a sawtooth disc ditch opener with a hay cutter for no-tillage sowing of grain.

Background technique

At present, based on the research level and development trend of the same kind at home and abroad, it can be seen that the conservation tillage technology has been a key promotion project of the Ministry of Agriculture in recent years. Break ground area to achieve less or no tillage. During the implementation, our province has introduced two models produced by Hebei "Nonghaha" and Xuchang "Haofeng". From the perspective of usage and effect, although it can realize ditching, fertilization, sowing, suppression and other processes, it is not yet The real no-till sowing should be called semi-no-till sowing, and it has the following disadvantages:

1. There is a rotary tillage device installed in front of the ditch opener, and the soil is rotated at intervals. The soil area is large, which does not meet the requirements of no-tillage seeders, and increases the load on the machine tool;

2. The machine is huge, the structure is complicated, the manufacturing cost increases, and the price is about 10,000 yuan;

3. Since crop straw and root stubble are difficult to be crushed, it is not conducive to seed implantation and emergence, and the quality of sowing is reduced;

4. The weight of the equipment is large, generally above 600 kg, and the traction resistance is large. It is difficult to work with commonly used wheeled tractors, especially when the load of the equipment is large;

5. Rotary tillage and ditching tools are easily entangled by straw and weeds, resulting in high failure rate and low operating efficiency, which affects the income of operators; to some extent, it brings difficulties to the large-scale promotion of conservation tillage.

The notched disc type no-tillage seeder imported from abroad is a typical no-tillage seeder, but it is not suitable for the planting mode and power matching in our country. The traction-type hitch has a large turning radius, which is not suitable for use by households in the vast rural areas of our country; secondly, due to the high fiber and hardness of straw and root stubble, it is not easy to cut, and it is impossible to achieve no-tillage sowing; thirdly, the production of 12 rows of full The cost of no-till seeder is more than 80,000 yuan, so it is difficult to popularize in our country.

Contents of the invention

In order to overcome the deficiencies of the above-mentioned prior art, the purpose of this utility model is to provide a sawtooth disc opener with a guillotine for grain no-tillage sowing, which can be matched with a wheeled tractor, is flexible, and has a low cost , and can achieve full no-tillage sowing, laying the foundation for the large-scale promotion of conservation tillage technology.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

In the no-tillage grain sowing sawtooth disc ditch opener with hay cutter, the power shaft of the planter is connected to the rotary tiller shaft through the gearbox, and several disc serrated knives are arranged on the rotary tiller shaft. The toothed knives on both sides of the disc serrated knife are in contact with the hay cutter, and the hay cutter is fixedly connected to the frame of the planter.

The sawtooth disc opener with hay cutter for grain no-tillage sowing, the disc sawtooth knife is composed of a connecting disc, a cutter disc and a toothed knife, and the connecting disc fixed on the shaft of the rotary tiller is provided with a knife There are evenly distributed toothed knives on the cutter head; the adjacent toothed knives are misaligned with each other, and the angles of the separated toothed knives are consistent, and the separated toothed knives are tangent to the guillotine.

In the no-tillage sowing of grains, the sawtooth disc opener with hay cutters can be set as a disc, a semi-disc or several equal fan-shaped discs.

The sawtooth disc opener with hay cutter for grain no-tillage sowing has a trapezoidal or triangular shape of the toothed knife, and the toothed knife can be set as single-edged or double-edged.

The sawtooth disc ditch opener with a guillotine for grain no-tillage sowing has a trapezoidal or triangular shape, and the guillotine can be set as single-edged or double-edged.

In the no-tillage sowing of grains, the sawtooth disc ditch opener with guillotine cutters, the connecting disc and the cutter disc can be integrated.

In the no-tillage sowing of grains, the sawtooth disc opener with guillotine cutters can be integrated with the cutter head and the toothed cutter.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages:

The sawtooth disc opener with hay cutter for grain no-tillage sowing uses the tractor as the power to drive the rotary tiller shaft of the planter through the tractor power output shaft, so that the disc opener cuts a soil gap of about 3cm , Implemented conservation tillage technology, under the premise of ensuring the germination of seeds, try not to damage the soil plow layer, reduce the area of broken soil, and achieve less or no tillage.

At the same time, under the interaction of the guillotine and the sawtooth knife, the stalks of the planting seedlings are crushed and fully mixed with the soil. No-tillage planting can be realized; and the efficiency is high, the manufacturing cost is low, and it can be widely popularized and applied.
