Abstract

The invention discloses a novel low-loss belt-type telescopic digging finger buckwheat picking device. A core mechanism of the device adopts a telescopic digging finger mechanism which is integrated in a front roller of a toothed belt picking device, and a flexible bottom plate is designed at the bottom of a picking table; and the device comprises the following main structures: telescopic diggingfingers (1), a driven roller (2), a chain wheel (3), a contour wheel (4), a picking belt (5), the flexible bottom plate (6), picking teeth (7), a driving roller (8), an auger (9), a baffle (10), a scraping plate conveyor belt (11), and an outer shell (12); the telescopic digging fingers (1) are integrated in the driven roller (2), and the telescopic digging fingers (1) and the driven roller (2) rotate at a same angular speed; the driven roller (2) is in drive connection with the driving roller (8) through a chain, and the driven roller (2), the auger (9) and the scraping plate conveyor belt (11) are separately installed on the outer shell (12) through a central shaft; and the flexible bottom plate (6) and the baffle (10) are fixed on the outer shell (12). The picking device provided by theinvention has the advantages of easy swath sending, clean picking and low grain dropping loss, and effectively reduces a picking loss rate.

Description

technical field

[0001] The invention belongs to the field of picking machines for segmental harvesting of small miscellaneous grains, in particular to a low-loss picker used for segmental picking and harvesting of buckwheat. Background technique

[0002] Buckwheat belongs to miscellaneous grain crops, which can be divided into sweet buckwheat and tartary buckwheat, and their geographical distribution is obviously different. my country's Huaihe River, Qinling Mountains, and Bashan Line (called the Qinhuai Line) are the transitional areas for the cultivation of sweet buckwheat and tartary buckwheat. Tartary buckwheat is unique to my country, and more than 90% of tartary buckwheat in the world is produced in my country. The mechanization level of buckwheat harvesting is very low, and manual harvesting is basically used, which is time-consuming, laborious and inefficient. Under the background of the current large-scale management of rural land, a large number of rural labor for...

Embodiment Construction

[0016] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0017] The low-loss belt-type retractable finger buckwheat picker of the present invention adopts a structure in which a retractable finger mechanism is integrated inside the front roller of the toothed-belt type picker, and a flexible bottom plate is designed at the bottom of the pick-up platform. The working process of the low-loss belt-type retractable finger buckwheat picker is: the retractable finger (1) and the pick-up belt (5) pick up the buckwheat that has been cut to dry and transport it to the auger (9) and the scraper conveyor belt ( 11), then the buckwheat is transported to the threshing and cleaning device by the scraper conveyor belt (11). The flexible bottom plate (6) is used to collect the falling grains caused in the buckwheat picking up and conveying process, and the baffle plate (10) is to prevent the buckwheat grains from ...
