Description

Graded seed selection device for peanut planting Technical Field The utility model relates to the field of grading seed selection, in particular to a grading seed selection device for peanut planting. Background Before the peanut seeds leave the factory, the shrunken seeds of the seed seeds need to be removed, the grain size of the shrunken seeds is smaller than that of the full seeds, therefore, the seeds are generally screened and classified in a vibration screening mode, the top of the vibration screening machine is a screening box, and the screening box is elastically connected with a supporting frame component below through springs. In prior art, single sieving mechanism is in carrying out the screening process, because the seed is directly discharged to the vibration sieve separator through the feeder hopper in, consequently the seed volume of entering is great, is in the state of stacking, consequently in order to satisfy effective screening purpose, must increase the length of vibration sieve separator, leads to the device area occupied to be great. Disclosure of utility model The utility model aims to solve the problems in the background art and provides a grading seed selection device for peanut planting. The grading seed selecting device for peanut planting comprises a vibrating box, wherein a vibrating motor is fixedly arranged below a bottom end plate of the vibrating box, an upper screening component is arranged above an inner cavity of the vibrating box, a lower screening component is arranged below the inner cavity of the vibrating box, a feeding mechanism is arranged at the upper end part of the vibrating box, a first feeding groove of the feeding mechanism is aligned with the upper part of the upper screening component, a second feeding groove of the feeding mechanism is connected with the upper part of the lower screening component, and a through hole which is communicated with the second feeding groove and the lower screening component is formed in the end plate of the vibrating box. As a still further scheme of the utility model, the feeding mechanism comprises a feeding hopper integrally formed above the first feeding groove and the second feeding groove, and a separation block with a triangular section is integrally formed at the top of the communication part of the first feeding groove and the second feeding groove. As a still further scheme of the utility model, the feeding mechanism further comprises a first guide block and a second guide block which are fixedly connected to two ends of the inner wall of the feeding hopper, a channel for seeds to pass through is arranged between the first guide block and the second guide block, and the channel is positioned right above the separation block. As a still further scheme of the utility model, the top of the first guide block is provided with an inward-inclined first inclined surface, and the top of the second guide block is provided with an inward-inclined second inclined surface.
