AI Technical Summary
Peanut seeds are prone to sticking to the screen during the screening process due to their high moisture content, which can clog the screen holes and affect the screening effect.
The device employs a combination of a fan and heating wire to dry the surface of peanut seeds with hot air. The combination of an air guide structure and a moving structure ensures that the hot air is blown evenly onto the peanut seeds to prevent them from sticking. At the same time, a shield is used to prevent the seeds from being blown out of the device.
It effectively prevents peanut seed skins or particles from adhering to the sieve, improving the screening effect and ensuring the smooth progress of the screening process.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-9 As shown, a grading and seed selection device for peanut cultivation includes a frame 1. A feed inlet 2 is fixedly connected to one end of the top of the frame 1, and the feed inlet 2 is inclined to guide the peanut seeds for subsequent screening. A screening box 3 is fixedly connected inside the frame 1, and a shield 16 is fixedly connected above the screening box 3. A first screen 4 and a second screen 5 are respectively installed inside the screening box 3. A square shell 6 is fixedly connected to the bottom of the feed inlet 2. Several fans 7 and heating wires 8 are respectively installed at one end inside the square shell 6. A square frame 10 is installed at the other end inside the square shell 6. Sliding rods 14 are fixedly connected to both sides inside the square shell 6. A fixing block 13 is slidably connected to the surface of the sliding rod 14. A toothed plate 12 is fixedly connected to one end of the fixing block 13. An air guide structure 11 is installed inside the square frame 10. A moving structure 15 is installed on the surface of the square shell 6.
[0024] The air guiding structure 11 includes several rotating shafts 112 rotatably connected inside the square frame 10. Air guide plates 111 and gears 113 are fixedly connected to the surfaces of the rotating shafts 112 respectively. The gears 113 mesh with one end of the rack plate 12. With the arrangement of the air guiding structure 11, when the rack plate 12 moves, it will drive the gears 113, rotating shafts 112 and air guide plates 111 to rotate together, so that the blown hot air can be guided by the air guide plates 111.
[0025] The movable structure 15 includes a motor 151 fixed to the back of the square housing 6 and a square block 153 fixed to the bottom of the inner cavity of the square housing 6. The output shaft of the motor 151 is fixedly connected to a transmission rod 152. The other end of the transmission rod 152 passes through the square block 153 and is fixedly connected to a turntable 154. A rocker arm 155 is hinged to the surface of the turntable 154. One end of the rocker arm 155 is rotatably connected to a rotating rod 156. One end of the rotating rod 156 is fixedly connected to a fixing plate 157. The fixing plate 157 is fixedly connected to the surface of the rack plate 12. With the movable structure 15, when guiding hot air, starting the motor 151 will drive the transmission rod 152 and the turntable 154 to rotate. When the turntable 154 rotates, it will drive the rocker arm 155 to deflect, thereby applying force to the rack plate 12 and making it move left and right.
[0026] The square outer shell 6 has a baffle 9 inside. The baffle 9 is located between the heating wire 8 and the square frame 10. When hot air blows forward, the baffle 9 can guide the hot air through the air guide structure 11.
[0027] A fixed long block 18 is fixedly connected between the two vertical plates at the top of the feed inlet 2. A bolt 19 is fixedly connected to the left side surface of the fixed long block 18. A sliding plate 21 is set between the two vertical plates at the top of the feed inlet 2. A square hole groove 22 is opened on the surface of the sliding plate 21, and the inside of the square hole groove 22 is slidably connected to the surface of the bolt 19. A nut 20 is threadedly connected to the surface of the bolt 19. With the setting of the square hole groove 22, the bolt 19 and the nut 20, when the nut 20 is removed from fixing the sliding plate 21, the sliding plate 21 can be moved up and down, thereby controlling the amount of peanut seeds poured in.
[0028] The top of the shield 16 is provided with several round holes and slots 17, which are provided to facilitate the dissipation of heat inside the shield 16.
[0029] Working principle: When workers are grading and selecting peanuts, they first start the machine and then pour the peanuts into the feed inlet 2, allowing them to slide down. As the peanuts slide down, they pass in front of the square shell 6. Then, the motor 151 is started. When the motor 151 rotates, it drives the transmission rod 152 and the turntable 154 to rotate. When the turntable 154 rotates, it drives the rocker arm 155 to deflect, thereby applying force to the rack plate 12. As the rack plate 12 moves, it drives the gear 113, the rotating shaft 112, and... The air guide plate 111 rotates, causing it to deflect left and right. At this time, the air blown out by the fan 7 is turned into hot air by the heating wire 8. The hot air then passes through the baffle 9 and blows onto the air guide plate 111. Subsequently, the hot air blows onto the falling peanut seeds, drying them. Then, the shield 16 blocks the peanut seeds that are blown further away. After that, the peanut seeds fall onto the first screen 4. Through the operation of the machine, peanut seeds of different sizes fall onto the second screen 5, and finally onto the screening box 3. Finally, the peanut seeds are collected through different outlets.
