Description

Stubble clearing and preparation operation assembly

technical field

The invention belongs to agricultural machinery, and mainly relates to a stubble clearing and preparation operation assembly for a seed bed in a large corn ridge with double rows.

Background technique

In northern China, especially Heilongjiang, Jilin and other provinces and regions in the northeast, in order to reduce the loss of soil moisture during spring sowing in dry fields, no-tillage sowing methods are vigorously promoted in agronomy, that is, directly on the stubble of the original crops of the previous season. The seeding operation is carried out without any pretreatment of the seedbed soil, which avoids the turning of the seedbed soil and reduces the evaporation loss of water in the soil. At present, in order to achieve no-tillage sowing and ensure the quality of sowing operations, no-tillage seeders are generally equipped with disc cutters, and the disc cutters are used to cut the stubble first, and then the seeder completes the sowing operation. However, in In production practice, its operating effect is too poor, and it is difficult for the disc cutter to cut the stubble accurately, which affects its popularization and application. In addition, in recent years, the agronomic technology of double-row corn planting has been widely used in Heilongjiang area. Because of its obvious effect of increasing yield and good product quality, it has been widely adopted by farmers. However, there is still no equipment for the cleaning and preparation of the seed bed in the corn large ridge double-row stubble field, and its no-tillage sowing agronomic technology cannot be applied.

Contents of the invention

The purpose of the present invention is to solve the problems in the above-mentioned prior art and combine the actual needs of the popularization and application of no-tillage sowing agronomic technology with large ridges and double rows of corn to design a special stubble clearing and preparation operation for seed beds with double rows of stubble corn Assembled, it achieves the purpose of small stubble clearing, reduced soil water loss, low power consumption, good stubble clearing quality, especially to meet and adapt to the purpose of stubble clearing and preparation operation of double row stubble seedbed in corn large ridge.

The purpose of the present invention is achieved in this way: the left drive shaft is supported and assembled on the left outer bearing seat assembly and the left inner bearing seat assembly, the stubble clearing left cutterhead assembly is fixed on the left drive shaft, The bearing seat assembly and the right inner bearing seat assembly are supported on the right drive shaft, and the stubble clearing right cutter head assembly is fixed on the right drive shaft. As a whole, it is arranged in the shape of a narrow front and a wide cone at the back, and the stubble clearing left cutter head assembly and the stubble clearing right cutter head assembly are respectively located above the left row of corn stubble and the right row of corn stubble on the large ridge platform, and the ten thousand The two ends of the transmission shaft are respectively fixedly installed with the inner ends of the left and right drive shafts, and the right drive shaft is connected with the left drive shaft, so far the stubble clearing and preparation operation assembly for the double row stubble field seed bed of corn large ridges is formed.

The invention adapts to and satisfies the needs of the stubble cleaning and preparation operation of the seed bed in the double-row corn field, and has the advantages of novel and reasonable structural design, high efficiency of stubble cleaning operation, good quality of seed bed preparation, less soil damage, low power consumption, and generalization The characteristics of high degree and wide application range.

detailed description

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A stubble clearing and preparation operation assembly for the seed bed of a large corn ridge with two rows of stubble, the left outer bearing seat assembly 2 and the left inner bearing seat assembly 3 are supported and equipped with the left drive shaft 10, and the stubble clearing left cutterhead assembly 1 is fixed on the left drive shaft 10, and the right drive shaft 13 is supported and fitted on the right outer bearing seat assembly 6 and the right inner bearing seat assembly 5, and the stubble clearing right cutter head assembly 7 is fixed on the right drive shaft 13 Above, the stubble clearing left cutterhead assembly 1 and the stubble clearing right cutterhead assembly 7 are arranged in a narrow front and rear wide cone shape as a whole, and the stubble clearing left cutterhead assembly 1 and the stubble clearing right cutterhead assembly 7 The left row corn stubble 11 and the right row corn stubble 12 on the big ridge platform 8 are respectively located above. Shaft 13 is connected to left drive shaft 10 .

When the operation is in use, utilize the left outer and inner bearing seat assemblies 2, 3 and the right outer and inner bearing seat assemblies 6, 5 to assemble the stubble clearing and preparation operation assembly on the work tool rack. The external transmission power drives the cardan shaft 4 and the left (or right) drive shaft 10 (or 13) to rotate through the right (or left) drive shaft 13 (or 10), driving the stubble clearing right and left cutter head assembly 7,1 Rotate, and finish the stubble clearing operation to right row corn stubble 12 and left row corn stubble 11 respectively, and throw right and left row corn stubble 12,11 to the right and left sides of big ridge platform 8 respectively. Inside the ditch 9. The right and left cutterhead assemblies 7 and 1, which are configured in a cone shape and driven to rotate, move forward with the tool, forming a spiral stubble cleaning operation curve, which ensures and improves the operation quality and efficiency of clearing double rows of corn stubble in large ridges. Effect.
