Embodiment 1
[0027] see Figure 1-3 , the present embodiment provides an agricultural seed screening device, comprising an outer shell 1, a feed inlet 2 is arranged above the outer shell 1, the feed inlet 2 is in the shape of an inverted trumpet, and the side of the outer shell 1 is arranged There is a slag outlet 3, a slag collection box 4 is arranged under the end of the slag outlet 3, a return pipe 5 is connected below the slag outlet 3, and the position corresponding to the return pipe 5 on the slag outlet 3 is a hollow structure , the outer shell 1 is provided with a partition 9 and a rotating plate 6, and a driving mechanism for driving the rotating plate 6 is also provided, and the driving mechanism includes a power source 14 and a rack 13. A support frame is arranged on the inner wall, and the power source 14 is fixed on the support frame, and the power source 14 is driven and connected with a driving wheel 20 through a transmission shaft, and the driving wheel 20 is provided with ...
Embodiment 2
[0034] see Figure 4 and Figure 5, on the basis of Embodiment 1, a sleeve 18 is provided on the partition 9, a ratchet 15 is provided on the shaft 11 corresponding to the upper end of the sleeve 18, and a gear ring 16 is movable above the sleeve 18 , the toothed ring 16 is meshed with the ratchet 15, and several guide plates 17 are connected to the toothed ring 16. The guide plates 17 are arc-shaped. Under the action of the ratchet 15 and the toothed ring 16, the toothed ring 16 The rotating shaft 11 can only rotate in one direction when the rotating shaft 11 alternates forward and reverse. In this way, the arc-shaped guide plate 17 can continuously guide the seeds to the outside and discharge them through the discharge port 10, making the discharge more convenient and thorough.
Embodiment 3
[0036] see Figure 6 and Figure 7 , on the basis of Embodiment 1, there is no limit to the selection of the limiting structure used to limit the rack 13. In this embodiment, another limiting structure used to limit the rack 13 is provided. The limiting structure includes a baffle 21, the baffle 21 has a "┌" type structure and the lower end of its vertical part is fixedly connected to the inner wall of the outer shell 1, the baffle 21 and the inner wall of the outer shell 1 form a chute, The rack 13 is arranged in the sliding slot. A number of rollers 22 are rotated on one surface of the chute that fits the rack 13, and the sliding connection is changed into a rolling connection, so that the resistance to the movement of the rack 13 can be greatly reduced. Limiting blocks 23 are provided at both ends of the chute, so that the rack 13 can be limited.
