Description

Technical Field

[0001] The invention belongs to the technical field of straw crushing, in particular to a single-row tall-stalk crop crushing and telescopic high-throwing integrated device. Background Art

[0002] Corn plants have male flowers and female flowers. The tassel at the top of the corn plant is the male flower that produces pollen, and the silks on the corn cobs are female flowers. The wind carries the pollen from the tassel to the silks of the cobs. The silks are connected to different individual embryos on the corn cobs. The pollen pollinates the embryos that develop into seeds. Normally, corn pollinates itself without human intervention.

[0003] In order to produce hybrid corn with improved characteristics, hybrid corn seeds with excellent characteristics are obtained by cross-pollinating the pollen of one corn variety with the silks on the ears of another variety. For cross-pollination between different varieties, it is necessary to selectively remove the male ears on the corn plant (maternal corn parent) and leave the female flowers, and use the male ear pollen from a different variety of corn plant (paternal corn parent) to perform cross-pollination on the female flowers on the maize mother parent.

[0004] In order to ensure the quality of pollination, 5-8 rows of maize parents are usually planted next to 1 row of maize father parent, and the maize father parent and the maize mother parent are planted alternately. After the maize father parent finishes pollinating the maize mother parent, cobs also grow on the maize father parent, but these cobs are self-pollinated with the male ears on the maize father parent, and the grains on the cobs of the maize father parent cannot be used as seeds. In order to avoid the cobs on the maize father parent from mixing with the cobs of the maize mother parent after they mature and reduce the purity of the seeds, and at the same time increase the ventilation, lighting, water and fertilizer supply of the maize mother parent, the entire maize father parent needs to be cut down after pollination is completed.

[0005] At present, the main methods for cutting off the male parent of seed corn are to manually cut down the male parent of corn from the root and leave the whole plant of corn parent in the field. Some farmers also use self-propelled stalk cutters. The self-propelled stalk cutter is to install a rotary cutter on the front end of a 2-wheel or 4-wheel self-propelled device. While the 2-wheel or 4-wheel self-propelled device is walking between the corn rows, the cutter rotates at high speed to cut the stalk of the corn parent into longer segments and leave them in the field. The method for processing the male parent of seed corn after hybridization and pollination abroad is to arrange a cutter on the wheel hub of the walking wheel of the elevated self-propelled device, let the walking wheel walk beside the row of corn parent, and cut the corn parent with the cutter on the wheel hub of the walking wheel. The operation efficiency of cutting the stalk of corn parent by the self-propelled stalk cutter and the method of arranging a cutter on the wheel hub of the walking wheel of the elevated self-propelled device is significantly higher than that of manual labor, but they all leave the corn parent in the field. The corn parent can be used as excellent silage, but the current method of removing the corn parent by cutting it and leaving it in the field causes a waste of agricultural resources.

[0006] Existing silage harvesters mainly include self-propelled and towed types. Self-propelled silage corn harvesters with high operating efficiency are currently commonly used, mainly including Germany's CLAAS JAGUAR series silage harvesters (850, 860, 870, and 980 models), which can harvest 6-12 rows of silage corn, have a cutting table width of 4.5-9m, and use non-row cutting tables, with high operating efficiency. For example, the 850 model has an operating efficiency of 150 acres / day. The American John Deer 8000 series (8200, 8400, 8500, and 8600 models) self-propelled silage harvesters have the same number of silage corn rows and cutting table width as the CLAAS JAGUAR series, and have high harvesting efficiency.

[0007] Domestic self-propelled silage harvesters include Xinjiang Mushen series self-propelled green (yellow) silage harvesters (4QZ-2200, 4QZ-3000 models), with operating widths of 2.2 and 3m respectively, and Hebei Muzhe green silage harvesters (4QZ-9, 4QZ-20 models), with operating widths of 2.9 and 3.24m respectively, both of which use non-row cutters.

[0008] These silage harvesters produced at home and abroad have been used in the process of silage corn harvesting in my country, but these silage harvesters have a small ground clearance and a wide cutting width, and cannot travel in seed corn fields to harvest single-row corn parents.

[0009] The difficulties in harvesting corn stalks as silage are as follows: (1) When harvesting corn stalks, the height of the corn plants is about 2m, and only an elevated self-propelled machine can be used to walk between the corn rows. The storage box for collecting the crushed corn stalks must be set up on an elevated chassis. Each time the corn stalks are harvested, a whole row must be walked, and the crushed corn must be dumped on the ground or in the transport box at both ends of the seed corn field. This requires that the storage box on the elevated self-propelled machine is large enough, resulting in the upper feeding port of the storage box being more than 4m above the ground. How to throw the crushed corn stalks into the very high storage box is the first difficulty. (2) On both sides of the corn stalk row are corn stalks. When harvesting corn stalks for silage, the corn stalks must not be damaged. This requires that the size of the crushing device should not be large while crushing the high-throw corn stalks. This is another difficulty in harvesting silage of seed corn stalks. Summary of the invention

[0010] In order to further solve the above problems, the present invention provides a single-row high-stalk crop crushing and retractable high-throwing integrated device, in which the guide wheel performs a diversion operation on the cut corn parent stalks, and then the stalks are cut off from the roots by the cutting knife, and then the corn parent stalks are conveyed through the conveying mechanism, and then the conveying roller combination further conveys the stalks upward to the material crushing mechanism, the disc knife crushing device crushes the stalks and throws them to the throwing device, and the outlet end of the throwing barrel in the telescopic high-throwing assembly conveys the crushed stalks to the storage box.
