Abstract

The invention relates to a belt type precision seed-metering device for rape, which comprises main devices such as a seed-metering belt (6), a seed protection device (4), seed cleaning devices (16) and the like, wherein a chain wheel (14) is connected with a driving shaft (15) through a key, and a driving belt wheel (5) is arranged on the driving shaft (15) and is connected with a driven belt wheel (8) through the seed-metering belt (6); the seed protection device (4) is connected with a front bracket (2) through seed protection brackets (3a1, 3a2, and 3a3) respectively; the seed cleaning devices (16a1 and 16a2) are connected to lower seed box brackets (7a2 and 7a4) through seed cleaning brackets (17a1 and 17a2); a seed guide tube (1) is arranged on a bottom plate (13); an upper seed box is arranged on a lower seed box (8); and the lower seed box (8) is connected with the bottom plate (13) and a rear bracket (12) through a lower seed box bracket (7a1) and a lower seed box bracket (7a2) respectively. The device can also be applied to plot seeders of other seeds with middle and small grain diameters.

Description

technical field [0001] The invention relates to the technical field of planting machinery in agricultural machinery, in particular to a belt-type precision metering device for rapeseed. By changing the seeding belts of different types and different hole diameters, it can also be used for other small and medium-sized seed plot breeding seeders. Background technique [0002] Small plots refer to the division of large plots into several small plots according to certain size specifications and breeding requirements, and there are intervals between plots and plots. Community breeding refers to the work of breeding, popularizing, purifying and rejuvenating improved varieties in the community; it is one of the important links of agricultural production. At present, the breeding of domestic rapeseed plots mainly adopts manual operations, involving many manual operations such as arable land, leveling, ditching, ridging, sowing, fertilization, soil covering, and leveling, which have ...
