Description

Misaligned cotton stalk harvester and its cotton stalk extraction harvesting table

technical field

The invention relates to a cotton harvesting device, in particular to a non-aligned cotton stalk harvester and a cotton stalk extraction harvesting platform.

Background technique

Cotton stalk harvesting is mainly harvested by plucking stalks. The main reason is that cotton stalks are hard and not easy to rot and crush, and they remain in the soil for a long time, which is not conducive to subsequent land preparation operations and crop growth, and cannot meet the agronomic requirements of "intensive farming". Cotton planting in my country mostly adopts film-laying to increase temperature and preserve moisture. The climate, soil, and varieties vary greatly across the country, and the row spacing of cotton planting is varied. Therefore, if a harvester for pulling cotton stalks in wrong rows can be developed, it will greatly increase the suitable harvest range, make full use of the geographical advantages of my country's north-south depth and length to carry out cross-regional operations, increase the harvesting area, and increase the income of machine harvesting.

The model that is widely used in China is the horizontal toothed disc cotton stalk puller, which drives the stalk pulling toothed plate through the ground wheel, and the rotating stalk pulling toothed plate and the stop rod constitute the stalk pulling part. After the cotton stalk enters the stalk pulling part, it is pushed to the root of the teeth of the stalk pulling tooth plate under the action of the retaining rod and clamped. The cotton stalk is dragged out by the walking of the tractor, and the cotton stalk is piled up by the pressure roller on the rear side. , put in the field. This model can only pull out 2 rows, and the efficiency is low. The plucking rate of the machine is greatly affected by the firmness of the soil and the planting row spacing of cotton. The plucking rate of the compacted land is low, and there are more cotton stalks cut off by the stalk discs, resulting in a large loss; Going into the field for picking operations is labor-intensive and comprehensively costly, and it is difficult to meet the requirements of comprehensive utilization of cotton stalks in my country.

At present, common cotton stalk extraction devices include rubber roller type extraction device, vertical tooth disc extraction device, clamping type extraction device and planer roller type extraction device. The first three extraction devices cannot be misaligned due to structural limitations. Poor adaptability. Although the fourth type of extraction device, the planer roller type extraction device, achieves non-alignment extraction, it needs to penetrate 10-20 mm into the soil when it works, which has a great effect on soil excavation, high energy consumption, and relatively large wear of the soil on the planer. , The worn planer leads to serious "missing" phenomenon. For example, the Chinese utility model patent with the patent number "ZL200420008333.0" and the name "Cotton Stalk Harvesting Baler" is "ZL200420087046.3" and the name is "Cotton Stalk Harvester Mechanism for Harvesting Cotton Stalks" The Chinese utility model patent belongs to the rubber roller structure, and the cotton stalks are extruded by the rubber rollers, so the cotton stalks must be harvested in opposite rows; the application number is "200810188680.9", and the cotton pulling rod disclosed in the Chinese invention application named "Cotton rod pulling machine" The machine has a complex structure and is easy to block. The form of the telescopic work of the fork can easily lead to unstable work. For example, the fork cannot continue to expand and contract when it encounters deformation such as field stones, tree roots, etc. during the telescopic process.

In recent years, the research on cotton stalk harvesting machines at home and abroad has made great progress, but almost all of the research is based on cotton stalk extraction. The harvesting method of cotton stalks is basically "throwing after pulling, picking after throwing". "Segmental harvesting mode, lack of research on joint operations, and research on the arrangement of cotton stalks after pulling and the separation of cotton stalks and soil after pulling is still blank.

Also be provided with small blade 341 on described stem-pulling tooth knife 34, the cutting edge 345 of described small blade 341 is straight edge or serrated structure, present embodiment preferably adopts cutting edge 345 to arrange the small blade 341 of zigzag to increase The frictional force between the stem pulling knife 34 and the cotton stalk 10 increases the ability of the stem pulling tooth knife 34 to grab the cotton stalk 10 . The small blade 341 is disposed on one side of the V-shaped sawtooth structure of the knife teeth 346 . The other side of the V-shaped sawtooth structure of the knife teeth 346 may also be symmetrically provided with the small blades 341 . The small blades 341 are preferably arranged in the same plane as the knife teeth 346 . The small blade 341 in this embodiment is riveted to the stem-pulling tooth cutter body 342 by a rivet 343 , and may also be connected by other means such as welding or threaded connection, or the small blade 341 and the cutter tooth 346 may be processed into an integral structure.

Improving the gripping ability of the stem-pulling knife 34 on the cotton stalk 10 can also be achieved by increasing the coefficient of friction. The present invention adopts the method that the small blade 341 with serrated cutting edge is set on one side of the stem-pulling knife 34 .

The cotton stalk extractor 3 adopts the form of a horizontal roller, and the stem extractor 34 is installed along the axial direction of the stem extractor roller shaft 31. The cotton stalk extractor 3 is driven by a hydraulic motor and realizes stepless adjustable speed. High speed is used in dense cotton planting areas, and low speed is used when the amount of straw is small or the density is low. When working, the cotton stalk extractor 3 rotates under the drive of the transmission system 2, and pushes the cotton stalk 10 forward as the cotton stalk harvester advances, so that the cotton stalk 10 is embedded in the tooth 346 of the stem extractor 34 and the small blade 341. In the alveolar, the generated frictional force overcomes the connecting force between the cotton stalk 10 and the soil and pulls up the cotton stalk 10 . Since the stem-pulling knife 34 is evenly arranged along the axial direction of the stem-pulling roller shaft 31, the tip of the stem-pulling tooth knife 34 is divided into grains, so the cotton stalks 10 within the harvesting width of the cotton stalk extracting device 3 can be embedded in the cotton stalk extractor 3. In the cutter teeth 346 of the stem tooth cutter 34, cotton stalks are not pulled out in opposite rows. Compared with the stem-pulling planer, the stem-pulling knife 34 has two working points, which is easy to grasp the cotton stalk and can generate a larger pulling force. On the other hand, the tooth knife 34 for plucking stems can not burrow into the soil when plucking the stalks, or only the front ends of the teeth 346 go deep into the ground. The agricultural film under it is broken or taken out directly, which is beneficial to the subsequent land preparation operation and the growth of the next crop. The cotton stalk extracting device 3 pulls out the cotton stalk 10 and throws it onto the finishing chain plate 41. At the same time, the soil 70 excavated by the cotton stalk extracting device 3 and the soil 70 entrained in the roots of the cotton stalk 10 are also thrown to the finishing chain plate along with the cotton stalk 10 41 on. Due to the difference in specific gravity between the cotton stalk 10 and the soil 70 , the cotton stalk 10 is supported on the L-shaped slat 414 of the finishing chain plate 41 , and the soil 70 falls into the groove 415 formed by the L-shaped slat 414 . Cotton stalks and soil move toward the chopping device 40 under the drive of the finishing chain plate 41, and the soil in the groove 415 is thrown onto the ground when the slats 414 are overturned. In addition to being applied to the cotton stalk harvester, the present invention can also be applied to the extraction operation of other stalk crops.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
