Description

Threshing device of sunflower seed combine harvester
Technical Field
The utility model relates to a sunflower seed harvester, in particular to a threshing device of a sunflower seed combine harvester.
Background
At present, agricultural departments and commercial departments have higher requirements on mechanical harvest of edible sunflowers, such as the requirements of shortening the harvest period, high harvest efficiency, small loss, less broken seeds, no scratch to the seed coat, less seed sorting impurities, sunflower disc collection and remaining as feed, straw chopping and returning to the field and the like. In particular, strict standards are established for commodity purchase of sunflower seeds, and peeled seeds are obtained if the peeling area of the sunflower seed shells reaches more than one third of that of whole seeds, so that the sunflower seed shells belong to unqualified products, and the sunflower seed shells are required to have consistent appearance quality, complete and full particles, cleanness, no pollution and uniform size and shape.
However, only part of the areas adopt mechanized harvesting, mainly emphasizes the mechanized harvesting of the sunflower for oil, and the mechanized harvesting of the edible sunflower is still in the development starting stage. Although there is edible sunflower harvester product production, the technology is not mature, and the following two problems mainly exist: firstly, harvesting in sections, namely harvesting the flower disc by a machine, then airing, and threshing by a manual or a threshing machine after seeds are dried. The defects that the harvest period is prolonged, a large amount of labor for carrying and airing the flower disc is occupied, and if the flower disc is improperly stored in rain, seeds are often wetted, mildewed and deteriorated; secondly, when the existing sunflower is harvested, most wheat harvesters and spike-tooth type threshing machines are used, the production rate is low, the seeds contain more impurities, the seeds are broken, the skins of the seeds are scratched more, and the purchase grade of finished products is reduced. The scratching and peeling of the seed coat mainly occurs in the process of sunflower threshing and conveying the seed to a granary after screening. The threshing mechanism applied to the traditional sunflower combine harvester is unreasonable in design, so that sunflower seeds are crushed or the epidermis is scratched, the product qualification rate and the product grade are greatly reduced, and the machines are difficult to popularize and apply.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a threshing device of a sunflower seed combine harvester, which can be matched with various types of sunflower combine harvesters for use, ensures that sunflower seeds are not crushed, does not scratch the skin, and can effectively improve the commodity rate.
The technical problem to be solved by the utility model is realized by the following structure: a threshing device of a sunflower seed combine harvester comprises a threshing device, a threshing cylinder, a fence type concave plate, a connecting plate, a conveying canvas and a straw shaker.
The threshing device is arranged on a frame of the sunflower seed combine harvester and is positioned behind the header feeding mechanism and at the front end of the sunflower disk conveyor. The function of the threshing mechanism is to take over the ungranulated sunflower discs fed by the header feeding mechanism for threshing. The sunflower disc with seeds removed is conveyed into a flower disc collecting box at the rear part of the combine harvester through a conveying canvas, a straw shaker and a flower disc conveyor.
The threshing cylinder consists of a cylinder shaft, a radial plate, a bracket, a threshing round roller, a connecting plate and a hoop. The threshing cylinder is arranged on the frame of the sunflower seed combine through a cylinder shaft. The wheel disk is welded on the roller shaft, 8 brackets are arranged on the periphery of the wheel disk through fixing bolts, and 8 threshing round rollers are transversely welded at the outer ends of the brackets. The cylinder shafts at the two ends of the threshing cylinder are provided with hoops so as to fix the threshing cylinder and prevent the threshing cylinder from moving left and right.
The outer side of the threshing cylinder is provided with a fence type concave plate. The fence type concave plate consists of a concave plate support, a fence and a connecting plate. In order to ensure that the threshing rate of the sunflower seeds is improved and the skin of the sunflower seeds is not broken, the minimum gap between the fence type concave plate and the outer end face of the threshing round roller is 30-50 mm; the wrap angle of the fence type concave plate relative to the threshing cylinder is 100-110 degrees. The fence is made of high-manganese round steel and is longitudinally welded on the outer frame of the concave plate, and in order to enable the taken-off grains to be smoothly discharged from the fence, the gap between the two fences is 20-25 mm. In the threshing process, when the ungranulated sunflower disc just enters a gap between the threshing circular roller and the fence type concave plate, the sunflower disc is subjected to multiple times of impacts on the outer end face of the threshing circular roller, most sunflower seeds are fallen off, and then the sunflower seeds close to the surface of the fence type concave plate move slowly and the sunflower disc close to the threshing circular roller moves quickly to generate a rubbing action, so that the sunflower seeds further fall off, and the fallen seeds fall to a cleaning mechanism below from the fence gap.
The conveying canvas is 4, one end of the conveying canvas is fixed with the threshing cylinder connecting plate through a fixing bolt and a fixing nut, and the other end of the conveying canvas is connected with the end parts of the 4 straw sorters. The sunflower disk separator has the function of receiving the cleaned sunflower disks discharged by the threshing cylinder, preventing the sunflower disks from falling onto a cleaning sieve below from a gap at the end part of the straw separator, sending the sunflower disks into the straw separator, and then sending the sunflower disks into a sunflower disk collecting box through a flower disk conveyor.
This thresher for sunflower seeds combine harvester advantage lies in: 1. the threshing and separating device has better threshing and separating performance, can ensure clean threshing, and has less crushing to sunflower discs; 2. the kernel is damaged less. The round roller type threshing cylinder ensures that the sunflower seeds are rubbed and dropped off when threshing, reduces the crushing of the sunflower seeds, avoids the abrasion of the surfaces of the seeds, has good separation performance of the seeds and impurities, and greatly improves the commodity rate of the seeds; 3. the universality is good, and the sunflower disc can be deoiled and eaten; 4. the rotation speed of the threshing cylinder is low and is only 300-400 rpm, and the power consumption is low; 5. the structure is simple, the manufacture is convenient, the harvester can be installed on different harvesters by slight modification, and the utilization rate of the combine harvesters of various types can be improved.
