Description

Technical Field

[0001] The present application relates to the technical field of seed cleaning machinery, and more specifically, to a seed desilting machine. Background Art

[0002] When facing different types of seeds, such as cereal / grain seeds, bean seeds, potato seeds and peanuts, their surfaces may be covered with mud when they are harvested. However, if the soil clods of some crops (such as corn) are not broken up when they are planted, it will have a certain impact on the germination and growth of the corn. Some crop seeds may germinate during storage because the environment reaches a suitable temperature. Therefore, it is necessary to remove mud from the harvested and stored seeds. However, the existing mud removal steps often use a screening machine to winnow and screen the crop seeds to achieve the purpose of cleaning the crops.

[0003] For example, a seed impurity removal agricultural machinery device with a current Chinese patent number of CN115041396B adjusts the position of the inner screening plate by adjusting the screws on the inner plate, thereby controlling the size of the screening hole. Smaller impurities pass through first and are discharged from the device through the fan impurity removal component. The size of the screening hole is adjusted to allow seeds to pass through, and the remaining large impurities remain on the screening plate. This device achieves the purpose of screening different impurities; large impurities are cleared out of the device at one time through the impurity cleaning mechanism; the outer screening plate is shaken by the cooperation of the cam and the shaking motor, thereby accelerating the screening speed; the height of the cam is adjusted by the movable leg plate, the bottom slider and the two-way threaded rod, thereby achieving the adjustment of the shaking amplitude of the outer screening plate.

[0004] However, the soil and seeds are mixed together. Although some of the soil will be sieved and separated, some of the soil will wrap the seeds. For example, the surface of crops growing in the soil, such as peanuts, potatoes, and radishes, will be covered with soil. The vibrating screening of the seed desilter and the blowing of the fan alone cannot screen out the soil outside the seeds, and this part of the seeds will be classified as impurities, resulting in low seed desilting efficiency. In view of this, we propose a seed desilter. Utility Model Content

[0026] See also Figure 1-3 ,This application provides a technical solution:

[0027] like Figure 1As shown, the main body 1 of the desilter is composed of a frame and a vibrating screen; a feed port is provided at the top of the frame, and a discharge port is provided at the bottom of the frame; the vibrating screen is composed of a screen 11 and a vibrator 12, the vibrator 12 is located at the bottom of the frame, and the screen 11 is located at the top of the vibrator 12. The core component of the vibrating screen is the vibrator 12, which is usually composed of a motor and an eccentric block. The motor drives the eccentric block to rotate to generate centrifugal force, and the centrifugal force is transmitted to the screen 11 via the vibrator 12, so that the screen 11 vibrates, and the material is introduced onto the screen surface of the screen 11 through the feed port. Under the action of the vibration force of the screen 11, the material produces continuous movement on the screen surface, and the material with smaller particle size is screened out through the screen 11, and the material with larger particle size slides along the screen surface and is discharged from the discharge port;

[0028] like Figure 2 and Figure 3 As shown, the top end of the eccentric block of the exciter 12 is rotatably connected to a connecting rod 21, and the other end of the connecting rod 21 is rotatably connected to a fixed plate 23, and the fixed plate 23 is set as an inverted T-shaped plate, and the fixed plate 23 is embedded in the inner side of the limiting slide 22, and the limiting slide 22 is fixedly set at the bottom end of the inner side of the mud remover body 1. Two slides are symmetrically provided on the side of the bottom end of the limiting slide 22, and the size between the two slides is equal to the size of the bottom end of the fixed plate 23. The bottom end of the fixed plate 23 can move inside the two slides to ensure the stability of sliding. The side of the bottom end of the fixed plate 23 is flush with the side of the slide, and one side of the bottom end of the fixed plate 23 is rotatably connected to the connecting rod 21. Two rubber pads are symmetrically fixed on the inner wall of the limiting slide 22, which can provide shock-absorbing protection for the fixed plate 23 that slides to one side of the limiting slide 22;

[0029] When the eccentric block in the exciter 12 rotates, it drives the connecting rod 21 rotatably connected thereto to move. The eccentric block rotates 360 degrees, and 360 degrees can be divided into the first quadrant, the second quadrant, the third quadrant and the fourth quadrant according to the plane rectangular coordinate system. When the eccentric block is in the first quadrant and the second quadrant, the eccentric block drives the connecting rod 21 to move forward, and the connecting rod 21 drives the fixed plate 23 to move toward the exciter 12. When the eccentric block is in the third quadrant and the fourth quadrant, the eccentric block drives the connecting rod 21 to move backward, and the connecting rod 21 drives the fixed plate 23 to move away from the exciter 12. When the eccentric block rotates one circle and drives the screen 11 to vibrate once, the fixed plate 23 performs a reciprocating movement.

[0030] like Figure 1 and Figure 2 As shown, the top of the linkage mechanism 2 is movably connected to the mud removal structure 3, and the mud removal structure 3 includes a connecting rod 21 fixedly connected to the top of the fixing plate 23, and a moving track 13 is slidably connected to the middle of the top of the connecting rod 21. Figure 4As shown, the movable track 13 is fixedly arranged in the middle of the desilter body 1, and one end of the movable track 13 is located below the feed inlet so as not to interfere with the entry of the seed crops, and the other end of the movable track 13 is located above the discharge port;

[0031] like Figure 2 and Figure 4 As shown, the other side of the movable track 13 is embedded in the inner side of the positioning groove 15, and the positioning groove 15 is fixedly arranged on the inner wall of the mud remover body 1, and the movable track 13 can slide freely in the inner side of the positioning groove 15, and a rack 14 is fixedly arranged at the bottom end of the positioning groove 15, and one side of the rack 14 can be meshed and connected with a gear 32, and the gear 32 is located at the bottom end of the positioning plate 31, and the gear 32 is rotatably connected with the positioning plate 31, and a fixed shaft is fixedly connected to the bottom end of the gear 32, and a cleaning plate 33 is fixedly connected to the bottom end of the fixed shaft, and the cleaning plate 33 is composed of a rotating circular plate and a plurality of brush strips, and the rotating circular plate is fixedly connected to the bottom end of the fixed shaft, and a plurality of brush strips are fixedly arranged at the bottom of the rotating circular plate, and the brush strips are located above the screen 11 and are in a position where they can contact the seeds on the screen 11, and do not directly contact the screen 11;

[0032] The reciprocating movement of the fixed plate 23 drives the positioning plate 31 to move reciprocally, and the other end of the positioning plate 31 slides smoothly on the inner side of the positioning groove 15. The positioning plate 31 slides along the moving track 13 while driving the gear 32 to move synchronously. The gear 32 is also affected by the rack 14 meshing with it, and then rotates while the gear 32 moves. The rotation of the gear 32 drives the cleaning plate 33 to rotate. When the cleaning plate 33 rotates, the brush bar at the bottom contacts the vibrating seeds and peels off the soil wrapped around the outside of the seeds through rotation. During the vibration of the screen 11, the seeds not wrapped by the soil will be screened out through the screen 11, and the cleaning process will continue after screening. The seeds wrapped by the soil will vibrate along with the screen surface, and the soil wrapped around the outside will be cleaned and removed under the synchronous action of the vibration force and the cleaning plate 33.

[0033] The seeds that need to be desilted and cleaned enter the desilter body 1 through the feed port of the desilter body 1, and the vibrator 12 starts the motor to drive the eccentric block to rotate, thereby driving the screen 11 to vibrate, and the seeds falling on the screen 11 vibrate accordingly. At the same time, the eccentric block rotates to drive the connecting rod 21 to move, and the connecting rod 21 drives the fixed plate 23 to move synchronously. When the eccentric block rotates one circle, the fixed plate 23 performs a complete reciprocating motion on the inner side of the limiting slide groove 22, and the fixed plate 23 moves to drive the positioning plate 31 fixedly connected thereto to move. The positioning plate 31 moves smoothly under the restriction of the middle moving track 13 and the side positioning groove 15, and the positioning plate 31 drives the gear 32 to move synchronously, and the gear 32 drives the cleaning plate 33 to move synchronously. While the gear 32 moves, it is affected by the meshing rack 14, and the gear 32 rotates while moving. The brush bar at the bottom of the gear 32 rotates and cleans the seeds. At this time, the cleaning plate 33 performs a reciprocating motion between the feed port and the discharge port, and the seeds on the screen 11 are desilted twice.
