[0003] In order to solve the deficiencies of the prior art, the utility model aims to provide a feeding device of a specific gravity sizing machine, which can effectively avoid blockage of the feeding device during use, ensure the effective transportation of seeds, and improve the work efficiency of the sizing machine.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A feeding device of a specific gravity sizing machine includes a hopper and a chute. The upper feeding port of the hopper is connected to the sizing machine body, and the chute is horizontally arranged at the lower discharging port of the hopper; the chute includes a U-shaped trough body and a vibrating feeding plate. The vibrating feeding plate is arranged in the trough body. The right end of the vibrating feeding plate away from the hopper is rotatably connected in the trough body, and the left end is arranged to move up and down; a vibrator installed in the trough body is connected to the lower left side of the vibrating feeding plate; an auxiliary feeding mechanism and an anti-blocking scraping mechanism are installed in the hopper. The anti-blocking scraping mechanism includes a scraper and a rotary driving component. The scraper is arranged to move closely along the inner wall of the hopper; the rotary driving component installed on the hopper is connected to the scraper and is used to drive the scraper to rotate along the inner wall of the hopper.

[0021] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and do not limit the scope of use of the present utility model.

[0022] As Figures 1-4 shown, the present utility model proposes a feeding device for a specific gravity separation machine, including a hopper 1 and a chute 2. The upper feeding port of the hopper 1 is connected to the main body of the separation machine, and the seeds from the main body of the separation machine enter the hopper 1 through the upper feeding port. The chute 2 is horizontally arranged, with its left side located at the lower discharge port of the hopper 1 and the right side being the discharge end. Specifically, the chute 2 includes a U-shaped trough body 21 and a vibrating feeding plate 22. The left end of the vibrating feeding plate 22 is higher than the right end and is inclined and arranged inside the trough body 21. The front and rear sides of the vibrating feeding plate 22 are in contact with the inner wall of the trough body 21 to prevent material leakage. The right end of the vibrating feeding plate 22 away from the hopper 1 is rotatably connected in the trough body 21, and the left end is arranged to move up and down; a vibrator 4 installed in the trough body 21 is connected to the lower left side of the vibrating feeding plate 22. Since the vibrating feeding plate 22 is inclined to the right, the vibration of the vibrator 4 can accelerate the conveyance of the material to the right and improve the conveying efficiency. In addition, a cushion plate 221 for resisting the impact of the material is provided above the left side of the vibrating feeding plate 22, which can reduce the impact of the material on the vibrating feeding plate 22 and improve its service life.

[0023] Specifically, the vibrator 4 includes a spring 47, a slide bar 42, a sleeve 43 and a third motor. The spring 47 is vertically installed between the vibrating feeding plate 22 and the trough body 21. Two springs 47 are symmetrically arranged on both sides of the slide rail 222 under the vibrating feeding plate 22, which can effectively support the vibrating feeding plate 22. Slide rails 222 are installed horizontally along the length direction of the bottom of the vibrating feeding plate 22, and sliders 41 are slidably installed on the slide rails 222. Among them, a T-shaped chute is opened in the slide rail 222, and a clamping portion matching the T-shaped chute is provided above the slider 41. Through the sliding cooperation of the slider 41 and the T-shaped chute, the connection stability between the slider 41 and the slide rail 222 can be improved. The slider 41 is hinged to the upper end of the slide bar 42. A groove 20 is opened at the bottom of the trough body 21, and the sleeve 43 is vertically installed at the opening of the groove 20. The slide bar 42 is vertically slidably sleeved in the sleeve 43. The lower end of the slide bar 42 is hinged to the upper end of the transmission link 44, and the lower end of the transmission link 44 is eccentrically rotatably connected to a turntable 45. The turntable 45 is vertically arranged in the groove 20, and the turntable 45 is concentrically fixed to one end of a horizontally arranged rotating shaft 46. The other end of the rotating shaft 46 penetrates through the trough body 21 and extends outwards and is connected to the third motor for power.

[0024] The vibrating blanking plate 22 is supported on the spring 47. When the third motor drives the rotating shaft 46 and the turntable 45 to rotate, the transmission connecting rod 44 eccentrically connected to the turntable 45 can move downward. Then, through the slide rod 42 and the slider 41, the vibrating blanking plate 22 is driven to swing downward with the right rotating connection as the center. When the transmission connecting rod 44 rotates upward and resets with the turntable 45, under the elastic force of the spring 47, the vibrating blanking plate 22 can be pushed up and reset. By repeating this cycle of actions, the vibrating blanking operation of the vibrating blanking plate 22 is realized, thereby significantly improving the conveying efficiency of the material in the chute 2 and avoiding the problem of material accumulation.

[0025] An auxiliary blanking mechanism and an anti-blocking scraping mechanism are installed in the hopper 1. The auxiliary blanking mechanism includes a feeding screw 3 and a second motor 31. The feeding screw 3 is vertically and rotatably installed in the middle of the hopper 1 through a bracket. The feeding screw 3 is provided with helical blades, and the upper end of the feeding screw 3 is power-connected to the second motor 31. The second motor 31 drives the feeding screw 3 to rotate, which can improve the conveying efficiency of the material in the hopper 1 and avoid material accumulation.

[0026] Among them, the anti-blocking scraping mechanism includes a scraper 14 and a rotation driving component. The scraper 14 is movably arranged close to the inner wall of the hopper 1. The rotation driving component installed on the hopper 1 is connected to the scraper 14 and is used to drive the scraper 14 to rotate along the inner wall of the hopper 1. The rotation driving component includes a rotating ring 11 and a first motor 13. The rotating ring 11 is horizontally and rotatably installed coaxially in the middle of the hopper 1. The scraper 14 is fixedly connected to the inner wall of the rotating ring 11. The outer wall surface of the rotating ring 11 outside the hopper 1 is provided with engaging teeth. A gear 12 is coaxially installed on the output shaft of the first motor 13 installed on the hopper 1, and the gear 12 meshes with the engaging teeth. Specifically, when implemented, the connection structure between the rotating ring 11 and the toothed ring can adopt the structure of a slewing bearing cooperating with a toothed ring in the prior art, which can realize horizontal rotation while ensuring sealing performance. By driving the rotating ring 11 to rotate through the first motor 13, the scraper 14 in the hopper 1 is driven to rotate closely along its inner wall for scraping, thereby effectively avoiding the problem of material sticking and accumulating on the inner wall of the hopper 1 and causing blockage, and thus improving the conveying efficiency of the blanking device.

[0027] When the utility model is in use, after the material enters the hopper 1, the conveying efficiency of the material can be improved under the spiral conveying of the feeding screw 3, and the rotation of the scraper 14 of the anti-blocking scraping mechanism can effectively scrape the material on the inner wall of the hopper 1, preventing the material from sticking to the inner wall of the hopper 1 and causing blockage problems. Then, when the material falls on the chute 2, with the vibration of the vibrating blanking plate 22 driven by the vibrator 4, the material in the chute 2 can be efficiently conveyed.
