Description

A no-tillage planter with a wide row of crops and a full amount of straw after throwing the broken straw

technical field

The utility model relates to a no-tillage seeder for straw field, in particular to a no-tillage seeder for planting wide row crops with broken straw and then throwing away the full amount of straw, belonging to the field of seeder technology.

Background technique

The seeder and straw pulverizer in the prior art generally work separately. The existing straw pulverizer cuts and pulverizes the previous stubble straw, cleans it, and then the seeder sows and fertilizes the land after the straw has been cleaned. When the straw grinder is working, it needs to comprehensively crush and clean the straw on the land to be sown, so the workload of the straw grinder is very large, the weight of the straw grinder itself is generally large, the working resistance is large, and the energy consumption is high. High; the efficiency of straw sowing is also low; in addition, the land after sowing is more vulnerable to damage from birds and insects and the harsh natural environment, resulting in a certain impact on the emergence rate and later growth of seedlings.

When sowing in the field, there is generally a certain distance between adjacent seed belts. If all the straw in the field is crushed and cleaned, it will cause waste of energy consumption. The sowing position of the device corresponds to it one by one, which simplifies the crushing process, greatly reduces resistance and power consumption, and reduces the weight of the whole machine, making the whole machine light and power-saving; at the same time, a small amount of crushed straw thrown backwards is evenly covered after sowing In the area of the seed belt, the uncrushed straw on both sides of the seed belt is distributed on both sides of the seed belt area, which provides a small environmental protection for the seeds and seedlings, reduces the damage to the seeds and seedlings by birds, insects and harsh natural environments, and greatly improves the emergence rate and It is beneficial for the seedlings to be neat and strong.

Further, the traction power mechanism is a tractor arranged at the front.

Further, each set of crushing cutters includes a plurality of cutter units fixed on the crushing shaft, and each cutter unit has a Y-shaped structure.

Further, the curved air channel is in the shape of a parabola, and the outlet at the end has a guiding structure to disperse the scattered objects.

Further, the traction power mechanism is an independent assembly unit, the crushing device 5, the lateral conveying device 6, the rear throwing device 2, and the seeding device 4 are an integral assembly unit, and there are rollers below the assembly unit.

Furthermore, the pulverizing device 5, the lateral conveying device 6, and the seeding device 4 are arranged sequentially from front to back.

Furthermore, a fertilization device 3 is also included, and the fertilization device is arranged between the seeding device 4 and the lateral conveying device 6 in the front and back direction.

The beneficial effect of the utility model is that

1) The straw within the width of the seed belt is crushed at one time, and the straw on the seed belt is crushed and thrown to the conveying auger through the crushing device, and the rear throwing device evenly throws the crushed straw on the surface after sowing, sowing and fertilizing, and improving work efficiency;

2) Reduce drag and reduce consumption: Reduce the crushing link, greatly reduce the resistance and power consumption, optimize the horizontal conveying device and lifting and spreading device, greatly reduce the weight of the whole machine, and the whole machine is light, saves power and consumption;

3) Seedling protection: provide micro-environmental protection for seeds and seedlings, greatly improving the emergence rate, and benefiting the growth of seedlings.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Referring to Fig. 1-Fig. 4, a no-tillage seeder with a wide row of crops and a full amount of stalks, including a traction power mechanism, a crushing device 5, a lateral conveying device 6, a rear throwing device 2, and a seeding device 4; The pulverizing device 5 includes a pulverizing shaft on which several groups of pulverizing knives are arranged at certain intervals, and each pulverizing knives correspond to various belts in the field; Adjacent, receiving the stalks crushed by the crushing device 5; the rear throwing device 2 is arranged at the end of the transverse conveying device 6, including a blade lifting device and a backward curved air duct; the seeding device 4 is arranged on the crushing device 5 In the rear and in front of the outlet of the curved air duct, there are seeding units corresponding to the positions of the crushing knives in the transverse direction.

In this embodiment, referring to FIG. 1 , the traction power mechanism is arranged on the frontmost tractor.

In this embodiment, referring to Fig. 2, according to the row spacing of crops, 4 groups of crushing knives are designed, each group of crushing knives are evenly distributed in the circumferential direction, and the position of each group corresponds to the position of the seed belt. During operation, each group of crushing knives only crushes the seed belt area Straw, which simplifies the crushing process and greatly reduces power consumption and resistance. In addition, each group of crushing knives includes multiple cutter units fixed on the crushing shaft, and each cutter unit has a Y-shaped structure.

In this embodiment, referring to FIG. 1 , the curved air duct is in the shape of a parabola, and the outlet at the end has a guiding structure to disperse the scattered objects.

In this embodiment, referring to FIG. 2, the traction power mechanism is an independent assembly unit, and the crushing device 5, the lateral conveying device 6, the rear throwing device 2, and the seeding device 4 are an integral assembly unit, and the assembly unit There are scroll wheels below.

In this embodiment, referring to Fig. 2, the pulverizing device 5, the lateral conveying device 6, and the seeding device 4 are arranged sequentially from front to back.

In this embodiment, referring to FIG. 2 , a fertilizing device 3 is also included, and the fertilizing device is arranged between the sowing device 4 and the lateral conveying device 6 in the front and rear direction.

When sowing in the field, there is a certain distance between the adjacent seed belts. If all the straw in the field is crushed and cleaned, the power consumption and operation cost are very large, and it also causes waste of energy consumption. The cutters are designed at intervals, and the sowing positions of the sowing device are corresponding to them one by one, which simplifies the crushing process, greatly reduces resistance and power consumption, reduces the weight of the whole machine, makes the whole machine light and power-saving; at the same time, it is thrown backwards on the The straw after sowing covers the ground of the seed belt, forming a very low amount of straw area, and the straw on both sides of the seed belt is not crushed, which provides a small environmental protection for the seeds and seedlings, and reduces the impact of birds, insects and harsh natural environment. The damage of seeds and seedlings greatly improves the emergence rate, which is beneficial to the growth of seedlings.

Referring to Figure 4, the sown seeds are covered by a low amount of crushed straw thrown back between AB (that is, between the uncrushed straws on both sides, that is, the seed belt area), and there are uncrushed straws on both sides, so that the seeds and seedlings are provided with microscopic Environmental protection, reduce the damage of birds and insects and harsh natural environment to seeds and seedlings, greatly improve the emergence rate, and help the seedlings to be strong.

Above is the preferred embodiment of the present utility model, those skilled in the art can also carry out various changes or improvements on this basis, on the basis of not departing from the general design of the present utility model, these changes or improvements should all belong to the present utility model Within the scope of the new type of protection.
