Embodiment 1

[0024] see Figure 1-4 , a multi-stage screening device for agricultural seeds, comprising a feed hopper 1 and a screening box 2, the four corners of the bottom of the screening box 2 are provided with universal wheels 4, the universal wheels 4 are provided with brake assemblies, and the brake assemblies The steering wheel 4 has a braking effect, and the setting of the universal wheel 4 is convenient for moving and fixing the device. The top center of the screening box 2 is connected with a feed hopper 1, and the feed hopper 1 is a funnel-shaped structure, which is convenient for seeds to enter the screening box 2. The bottom of the feeding hopper 1 extends into the inside of the screening box 2, and the bottom of the feeding hopper 1 is provided with a multi-stage vortex screen 7 inside the screening box 2, and the bottom of the multi-stage vortex screen 7 is fixedly connected with a multi-stage inclined screen 8. The bottom of the multi-stage inclined screen 8 is provided w...

Embodiment 2

[0029] see Figure 5 , on the basis of Embodiment 1, the upper surface of the eccentric wheel 10 is solemnly provided with several balls 20, and the inner top of the nesting groove 9 is provided with a ball groove 21, and the balls 20 are nested inside the ball groove 21, and the balls 20 and the ball groove 21 The setting reduces the frictional force of eccentric wheel 10 rotation, makes eccentric wheel 10 rotate more comfortably, has increased the stability of multistage vortex screen 7 and multistage inclined screen 8 swings simultaneously.

Abstract

The invention relates to the technical field of agricultural machinery, and specifically discloses a multi-stage screening device for agricultural seeds, comprising a feeding hopper and a screening box. The central position of the top of the screening box is connected with the feeding hopper, and the bottom of the feeding hopper extends Entering into the screening box, a multi-stage vortex screen is arranged inside the screening box. The bottom of the multi-stage vortex screen is fixedly connected with a multi-stage inclined screen. The bottom of the multi-stage inclined screen is provided with a nesting groove. A motor is fixedly installed at the inner middle position, and an eccentric wheel is connected to the output shaft of the motor, and the eccentric wheel is slidingly nested inside the nesting groove; the bottom of the multi-stage inclined screen is connected to the upper end of the hose, and the side wall of the screening box is provided with multiple Level seed outlet, multi-level seed outlet is communicated with the bottom of the hose, the inner bottom of the screening box is provided with a sloping plate, the end of the inclined plate is provided with a waste residue outlet on the inner side wall of the screening box, and the outer side wall of the screening box is provided with a controller . The invention has the advantages of simple structure, convenient operation, low production cost, smooth screening, and multi-stage screening.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a multistage screening device for agricultural seeds. Background technique [0002] my country is a large agricultural country, and agriculture is also the foundation of a country's development.
