Vertical seeding band cleaner

Abstract

The invention provides a vertical seeding band cleaner comprising a vertical shaft, a vertical shaft seat, two thrust ball bearings, connecting bolts, a frame, a small bevel gear, a connecting plate, a pressure plate, bolts, rotary blades, a transverse shaft, a large bevel gear, and compaction rollers. The vertical shaft penetrates the vertical shaft seat and is fixed on the vertical shaft seat through the thrust ball bearings. The vertical shaft seat is mounted on the frame through the connecting bolts. The small bevel gear is fixedly mounted at the upper end of the vertical shaft. The connecting plate is fixedly mounted at the lower end of the vertical shaft. The pressure plate is disposed below the connecting plate. The rotary blades are fixed between the connecting plate and the pressure plate through the bolts and are symmetric about the axis of the vertical shaft. The compaction rollers are disposed in front of the vertical rotary blades and connected to the frame through a connecting rack. The compaction rollers are distributed on a compaction roller shaft and can optionally rotate around the axis. The vertical seeding band cleaner is capable of cleaning straws and stubbles and loosening and crushing topsoil and has low vibration during operating process and low power consumption, and operating quality of a no-tillage planter can be improved effectively.

Description

technical field [0001] The invention provides a seedling strip cleaning device for crushing straw, stubble and broken grass, which belongs to the technical field of crop sowing. Background technique [0002] At present, in most areas of China, corn is sown immediately after wheat is harvested. Before sowing, wheat harvesters cannot handle straw, stubble, and broken grass in real time, which makes sowing difficult; The link is time-consuming and labor-intensive, which delays the farming time and makes it difficult to ensure timely sowing of corn. Therefore, in order to save farming time, farmers in many areas use incineration to dispose of straw, which not only pollutes the air, but also easily causes fires; Can cause jamming of openers during planting. In addition, the surface is hard after long-term precipitation and rolling by wheat harvesters, which makes it difficult for openers to penetrate the soil, and it is difficult for the sowing depth to meet the agronomic requi...

Problems solved by technology

[0002] At present, in most areas of China, corn is sown immediately after wheat is harvested. Before sowing, wheat harvesters cannot handle straw, stubble, and broken grass in real time, which makes sowing difficult; In this link, it is time-consuming and labor-intensive, delaying the farming time, and it is difficult to ensure timely sowing of corn

Therefore, in order to save farming time, farmers in many areas use incineration to dispose of straw, which not only pollutes the air, but also easily causes fires; Can cause jamming of openers during seeding

In addition, after a long period of sedimentation and rolling by wheat harvesters, the surface of the ground is hard, making it difficult for openers to enter the soil, and the sowing depth is difficult to meet the agronomic requirements. This has also become one of the main bottleneck technologies affecting the promotion of no-tillage sowing technology.

[0003] Cutting the grass, loosening the soil and clearing the seedlings are the main technical measures to solve the above problems. At present, the technology of the seeder to solve the anti-congestion mainly has two forms. One is to add a rotating roller type anti-congestion device, such as the development of the patent No. The anti-entanglement roller device of the ditch seeder is equipped with a rotatable roller in front of the opener column to move the straw in front of the opener to both sides of the opener. However, when there is a large amount of straw coverage, When the humidity of the surface soil is high, the rotary rollers often cannot turn the straw to one side in time, and sometimes even the rotary rollers are blocked, which cannot play the role of preventing congestion; in addition, this structure can only clean up the surface straw, and cannot affect the surface soil and roots. The stubble is loosened and crushed, so the normal operation of the no-tillage planter cannot be guaranteed

The other is a seedling belt cleaner, such as the planter with a seedling belt cleaner with a patent number of 102415234, which uses a rotary knife type chopping device to crush straw and loosen the soil, which solves the problems of crushing straw to prevent congestion, loosening soil on the ground The problem of ditching, but because the rotary cutting process is to compress the straw on the ground surface for unsupported chopping, not only the power consumption is large, but also because the rotary knives are rotary cutting in the same direction, the vibration of the machine tool is severe during the operation process, which seriously affects the planter. life and quality of work; and the rotary cutting method of loosening the soil is uneven, and the width of the ditch is too narrow, which makes it difficult to create a good growth environment for the growth of crop roots; of course, the rotary knife of the device has only one cutting edge, which cannot be replaced Position extends tool life, increases rotary knife replacement frequency and spare parts cost
