Description

Corn stalk returning machine based on uniform force vibration-free method

1. Field of the invention

The invention relates to the technical field of crop instruments, in particular to the fields of environmental protection and mechanical mechanism design research.

2. Background of the invention

Most of the countries in the world with developed agriculture pay great attention to the combination of land utilization and ecological agriculture development, and straw returning and farmyard manure account for 2/3 of the total fertilization amount. In the United states, straw returning is very common, and not only a large amount of straws such as corn and wheat are returned to the field, but also straws such as soybean and tomato are returned to the field as much as possible.

At present, crop straws are rarely used for returning to fields in China, and due to the fact that effective field returning measures are not adopted in most areas, continuous year planting of cultivated land cannot be leisure, effective soil components cannot be supplemented timely, soil organic matter content is reduced year by year, the average content of soil organic matter in China is only 1.5%, the average content of soil organic matter in America is less than half of the average content of soil organic matter in America, and agricultural production is in a heavy-use and light-culture predatory operating state. The straw returning technology has great development potential.

A large amount of straws are returned to the farmland in an incineration mode, so that a large amount of organic matters cannot return to the farmland, and the material circulation of the farmland ecosystem is damaged. In addition, the smoke generated by burning the straws not only causes environmental pollution, but also directly kills part of organisms on the surface layer of the soil, and the soil organisms have important influence on the improvement of the soil and the formation of soil fertility. The corn straw is directly returned to the field, so that the physical condition of the soil can be improved, the volume weight of the soil is reduced, the porosity is increased, and the permeability of the soil is increased.

The corn straw contains various nutrient elements, is an important organic fertilizer source, and is an effective measure for improving the organic matter content of soil and fertilizing the soil fertility. Therefore, returning the corn straws to the field is an important link in the biological cycle of farmland soil substances, is an important measure for reasonably utilizing resources, reducing environmental pollution and improving soil fertility, and is advocated vigorously; so the corn straw returning machine has more and more functions.

3. Summary of the invention

The invention aims to provide a corn straw returning machine based on a uniform force vibration-free method, which mainly comprises a hammer claw 1, a knife roller 2, a small belt pulley 3, a tension pulley 4, a large belt pulley 5, a bearing end cover 6, a large bevel gear 7, a universal joint transmission shaft 8, a bearing 9, a small bevel gear 10, a reduction box body 11 and a balance wheel 12. The cutting effect of the corn straw returning machine is characterized in that the arrangement mode of blades on the hammer claw 1 is adopted, the reasonable arrangement mode not only can improve the crushing quality of the returning machine, but also can ensure that the returning machine has good balance performance and the vibration of the returning machine is reduced, and the invention adopts the arrangement mode of a uniform force vibration-free method. When the field returning machine works, the power of a tractor is transmitted to the reduction box body 11 through the universal joint transmission shaft 8, the output shaft of the reduction box body 11 drives the belt pulley, the belt pulley is driven to accelerate, the knife roller 2 drives the hammer claw 1 to rotate at a high speed, the corn straws are stirred to enter the broken-line type shell, and after the hammer claw 1 and the knife roller 2 are sheared, hammered, torn and cut, the corn straws are thrown to the rear edge of the field returning machine and are scattered in the field.

The working principle of the invention is as follows: when the corn straw returning machine based on the uniform force vibration-free method works, the power of a tractor is transmitted to the reduction box body 11 through the universal joint transmission shaft 8, the output shaft of the reduction box body 11 drives the small belt pulley 3 and the large belt pulley 5, and the small belt pulley and the large belt pulley are adjusted by the tension pulley 4. The cutting effect of the corn straw returning machine is characterized in that the arrangement mode of the blades of the hammer claw 1 is adopted, the crushing quality of the returning machine can be improved due to the reasonable arrangement mode, the balance performance of the returning machine can be good, and the vibration of the returning machine is reduced. Based on the traditional single-spiral arrangement, double-spiral arrangement, star arrangement and symmetrical arrangement modes, the machine designs a new arrangement method, namely a uniform force seismic isolation method. When the machine works, a larger impact load needs to be borne, and the cutter roller 2 driving the blade to rotate needs a higher rotating speed, so that a single-stage conical helical gear reducer is adopted. The arrangement mode of blades on the hammer claw 1 is of great importance for straws, the reasonable arrangement mode can not only improve the crushing quality of the returning machine, but also improve the balance of the corn straw returning machine through the balance wheel 12 and reduce the vibration of the returning machine. Through two-stage speed change, the crushing roller drives the hammer claw 1 to rotate at a high speed, the corn straws are stirred to enter the broken line type shell, and after being sheared, hammered, torn and cut by the hammer claw 1 and the shell knife roller 2, the corn straws are thrown to the rear edge of the field returning machine and are scattered in the field.

The cutter of the machine is a cone claw type blade, and is characterized in that the blade is large in mass, large in rotational inertia and good in striking performance, and mainly combines striking and cutting in a grinding mode. When the machine works, a larger impact load needs to be borne, and a cutter roller driving a cutter to rotate needs a higher rotating speed, so that a single-stage gear reduction device is adopted. The power of the tractor is transmitted to the gear box through the universal joint, the output shaft of the gear box drives the belt pulley, and the two-stage speed increasing enables the crushing roller to drive the hammer claw to rotate at a high speed, stir corn straws to enter the broken-line type casing, and the corn straws are sheared, hammered, torn, cut and shredded by the hammer claw and the casing stationary knife, then thrown to the rear edge of the field returning machine and scattered to the field.
