Description

Technical Field

[0001] This invention belongs to the field of straw crushing technology, specifically an integrated device for crushing and retractable high-throwing of single-row tall crops. Background Technology

[0002] Corn plants have male and female flowers. The tassel at the top of the corn plant is the male flower that produces pollen, while the silks on the corn ear are the female flowers. The wind carries the pollen from the tassel to the silks on the ear, and the silks connect with different individual embryos on the corn ear. The pollen pollinates the embryos that develop into seeds. Under normal circumstances, corn self-pollinates without human intervention.

[0003] To produce hybrid maize with improved characteristics, cross-pollination is performed by using pollen from one maize variety to cross-pollinate the silks on the ears of another variety, thereby obtaining hybrid maize seeds with superior characteristics. To facilitate cross-pollination between different varieties, it is necessary to selectively remove the male tassels from the maize plant (maternal parent) and leave the female flowers. Pollen from the male tassels of different maize plants (paternal parent) is then used to cross-pollinate the female flowers on the maize plant.

[0004] To ensure pollination quality, it is common practice to plant 5-8 rows of maize female plants next to one row of male maize plants, alternating between the male and female plants. After the male maize plants pollinate the female plants, they also grow ears of corn. However, these ears are self-pollinated by the tassels on the male maize plants. The kernels on the ears of the male maize plants cannot be used as seeds. To avoid the ears of the male maize plants from mixing with the ears of the female maize plants after maturity and reducing seed purity, and to increase ventilation, light exposure, water and fertilizer supply to the female maize plants, the entire male maize plant needs to be cut down after pollination.

[0005] Currently, the main methods for removing male parents in seed production maize include manually cutting them down from the root and leaving the entire plant in the field, and some farmers using self-propelled stalk cutters. These machines have rotating blades attached to the front of a two- or four-wheeled self-propelled device. As the device moves between the maize rows, the blades rotate at high speed, cutting the stalks of the male parents into longer segments that are left in the field. In other countries, the method for handling male parents after hybridization and pollination of seed maize involves arranging blades on the hubs of elevated self-propelled devices, allowing the devices to travel alongside the rows of male parents and using the blades on the hubs to cut them. The self-propelled stalk cutter and the method of arranging blades on the hubs of elevated self-propelled devices are significantly more efficient than manual labor. However, both methods leave the male parents in the field. While the male parents can be used as excellent silage, the current methods of removing these cut and left-in plants result in a waste of agricultural resources.

[0006] Existing silage harvesters are mainly self-propelled and towed. Currently, the most commonly used are high-efficiency self-propelled silage corn harvesters, such as the German CLAAS JAGUAR series silage harvesters (models 850, 860, 870, and 980). These harvesters can harvest 6-12 rows of silage corn, with a cutting table width of 4.5-9 meters. They use non-row cutting tables, resulting in high operating efficiency. For example, the 850 model has an operating efficiency of 150 mu / day. The American John Deer 8000 series (models 8200, 8400, 8500, and 8600) self-propelled silage harvesters have the same number of rows of silage corn harvested and cutting table width as the CLAAS JAGUAR series, and also have high harvesting efficiency.

[0007] Domestically produced self-propelled silage harvesters include the Xinjiang Mushen series self-propelled silage (yellow) harvester (4QZ-2200, 4QZ-3000 models), with working widths of 2.2m and 3m respectively, and the Hebei Muze forage harvester (4QZ-9, 4QZ-20 models), with working widths of 2.9m and 3.24m respectively. Both adopt non-row cutting platforms.

[0008] These domestic and foreign-made silage harvesters have been used in the harvesting of silage corn in my country. However, these silage harvesters have a small ground clearance and a wide cutting width, and cannot travel in seed corn fields to harvest single-row male corn.

[0009] The difficulties in harvesting male corn for silage are: (1) When harvesting male corn, the height of the corn plants is about 2m, and only elevated self-propelled machinery can be used to walk between the corn rows. The storage box for collecting crushed male corn must be set up on the elevated chassis. Each time male corn is harvested, it is necessary to walk through an entire row and dump the crushed corn on the ground or into the transport vehicle at both ends of the seed corn field. This requires the storage box on the elevated self-propelled machinery to be 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 to the very high storage box is the first difficulty. (2) The maternal corn plants are on both sides of the male corn row. When harvesting male corn for silage, the maternal corn plants must not be damaged. This requires that while crushing the corn stalks at a high throw, the volume of the crushing device cannot be large. This is another difficulty in harvesting male corn for seed silage. Summary of the Invention

[0010] To further address the aforementioned problems, this invention provides an integrated device for single-row tall crop crushing and retractable high-throwing. A guide wheel guides the cut corn stalks, which are then severed at the root by a cutter. The corn stalks are then conveyed by a conveying mechanism, and further upwards by a conveying roller assembly to the material crushing mechanism. A disc crusher crushes the stalks and throws them to a throwing device. The outlet of the throwing cylinder in the retractable high-throwing assembly conveys the crushed stalks to a storage bin.

[0033] like Figure 2-6 As shown, the material crushing mechanism 7 includes a drive motor 7-1 and a disc crusher 7-2. The material crushing mechanism 7 is fixed on crossbeam 5-9 and crossbeam 5-10. The disc crusher 7-2 is a disc-type cutting and crushing machine. The drive motor 7-1 is used to drive the disc crusher 7-2 to rotate and crush at high speed. The two conveying rollers are driven by the conveying roller drive motor 6-4 to feed the material from the inlet of the disc crusher 7-2 to achieve crushing. The crushed material is then thrown into the telescopic high-throw assembly 8 through the outlet of the disc crusher 7-2.

[0034] When the optimal rotation speed of the stalk pulling device assembly 4 is 140 r / min, the optimal rotation speed of the conveying mechanism assembly 6 is 280 r / min, and the rotation speed of the disc crusher 7-2 is 2000-2400 r / min, this setting can ensure that the stalks complete the optimal crushing operation after entering the material crushing mechanism 7.

The lower cylinder ear ring of the telescopic cylinder 8-1 is hinged to the single-ear ring interface of the crossbeam 5-18. The telescopic sleeve inner cylinder 8-2-3 is fixedly connected to the sleeve fixing plate 8-2-4. The telescopic sleeve inner cylinder 8-2-3 is installed inside the telescopic sleeve outer cylinder 5-21. Reinforcing ribs are provided on the rear and left sides of the telescopic sleeve outer cylinder 5-21 to ensure the strength of the telescopic sleeve.

There is a small gap of 3-5mm on both sides to realize the lifting and lowering of the guide air duct assembly 8-2, and at the same time, it is easy to clear the blockage when the material is blocked; the air duct 8-2-1 and the throwing cylinder 8-3 are connected by a circular connecting plate, and the throwing cylinder 8-3 can be rotated; a guide throwing cover 8-4 is also installed at the upper end of the discharge port of the throwing cylinder 8-3.

[0037] The throwing cylinder 8-3 is arc-shaped;

[0038] The air duct 8-2-1 has an air outlet size of 150×130mm, and the material throwing cylinder 8-3 has a throwing port diameter of 150mm, which facilitates the efficient throwing of materials after they have been crushed by the material crushing mechanism 7.

[0039] The beneficial effects of this invention are:

[0040] 1. This invention provides an integrated device for crushing and telescopic high-throwing tall crops. By rationally designing the specific structure and relative positional relationship of the speed reduction frame (1), transmission assembly (2), cutter conveying mechanism assembly (3), reeling device assembly (4), fan frame (5), conveying mechanism assembly (6), material crushing mechanism (7) and telescopic high-throwing assembly (8), it realizes the integrated operation of cutting, conveying, crushing and high-throwing tall crops in a single row, thereby improving the work efficiency.

[0041] 2. By carefully designing the transmission ratio of each transmission component in the transmission assembly (2), the conveying distance and gap of the cutter conveying mechanism assembly (3), the rotation speed of the reeling device assembly (4), and the special shape structure and specific parameters of the two conveying rollers in the conveying mechanism assembly (6), the optimal transmission of crops is achieved, providing a good foundation for subsequent crushing. This solves the problems of uneven crushing and missed crushing caused by the current unsatisfactory crop conveying, and realizes fine and precise operation.

[0062] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0063] Example

[0064] like Figure 1 and Figure 2 As shown, before operation, the entire tall crop crushing and telescopic high-throwing integrated device is installed on the elevated self-propelled drive platform. The transmission motor 2-1, material crushing mechanism 7, and conveyor roller drive motor 6-4 on the tall crop crushing and telescopic high-throwing integrated device are connected to the power source on the elevated self-propelled drive platform. Adjust the telescopic cylinder 8-1 to adjust the height of the guide air duct assembly 8-2, and then adjust the height position of the throwing cylinder 8-3 so that the throwing cylinder 8-3 can throw the crushed tall stalks to the storage box. Adjust the wheel track of the elevated self-propelled drive platform so that the wheels travel on the ground between the corn rows. Adjust the position of the whole machine so that the center of the cutting device on both sides is aligned with the corn row. Start the switches of the transmission motor 2-1, conveyor roller drive motor 6-4, and material crushing mechanism 7 to make the cutting conveyor assembly 3 and the picking device assembly 4 rotate.

[0065] The self-propelled drive platform of the starting frame moves. First, the rotating cutter 3-2 cuts the corn stalks. At the same time, the guide wheel 3-3 can smoothly transport the cut corn stalks. The corn stalks enter the reeling device assembly 4 from the cutter conveying mechanism assembly 3. After the reeling device assembly 4 pushes the cut corn stalks into the conveying mechanism assembly 6, the corn stalks will directly enter the material crushing mechanism 7 for crushing. After crushing, the material is thrown through the telescopic high-throw assembly 8.

[0066] The specific process is as follows:

[0067] Step 1: Cutting the corn stalks. The crop stalks are cut off by high-speed rotating blades, and the roots are cut off. This process is driven by the drive motor 2-1. The crop is transported at an angle to the position of the picking device assembly 4 through the cutter conveyor assembly 3. The picking device assembly 4 picks the crop into the conveyor assembly 6 and then conveys it to the material crushing mechanism 7 to crush the corn stalks.

[0068] Step 2: The crushed stems are thrown into the storage box by the throwing cylinder 8-3. This step helps to disperse the crushed stems, which is convenient for subsequent processing.

[0069] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent methods or modifications that do not depart from the technology of the present invention should be included within the scope of protection of the present invention.
