Automatic wheat seed cleaning and screening machine

Abstract

This utility model relates to the field of screening machines, specifically an automatic wheat seed cleaning and screening machine. It includes a machine body with an inlet at the top left side and an outlet at the bottom left side. This utility model employs a separation mechanism. A motor drives a connecting rod to rotate, which in turn drives a separation paddle to rotate, breaking up the seeds entering the separation seat. The broken seeds then contact the separation plate. During the rotation of the connecting rod, a convex plate rotates, pushing a protrusion to move. This protrusion then moves a connecting frame, which in turn causes the separation plate to oscillate inside the separation seat. This design prevents seeds from clumping and clogging the screen holes. It solves the problem that some wheat seeds, due to their high moisture content, are prone to clumping. Clumped seeds, when passing through the screen, can cause blockage of the screen holes, affecting screening efficiency and potentially leading to equipment malfunction.

In mechanized agricultural production, the quality of wheat seeds can be improved through automatic cleaning and screening machines. These machines can efficiently remove impurities, broken grains, and imperfect grains, providing pure and high-quality seeds for subsequent sowing or processing.

[0003] However, during the use of existing automatic cleaning and screening machines, some wheat seeds are prone to clumping due to their high moisture content. When the clumped seeds pass through the screen, the internal sieve holes become blocked, which affects the screening efficiency and may even cause equipment failure. Utility Model Content

When these clumped seeds pass through the sieve, they can cause blockages inside the sieve holes, thus affecting the seed screening efficiency and potentially leading to equipment malfunctions. This utility model proposes an automatic wheat seed cleaning and screening machine.

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] This application discloses an automatic wheat seed cleaning and screening machine. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The automatic wheat seed cleaning and screening machine includes a body 1, an inlet 3 on the top left side of the body 1, an outlet 4 on the bottom left side of the body 1, a second discharge outlet 10 on the bottom right side of the body 1, a guide plate 11 fixedly installed on the top of the inner cavity of the body 1, a screen 5 fixedly installed on the bottom of the inner cavity of the body 1, an observation window 6 fixedly installed on the front side of the inner cavity of the body 1, and a separation mechanism 2 installed on the right side of the inner cavity of the body 1.

[0027] The separation mechanism 2 includes a motor 201 and a separation seat 204. The front side of the motor 201 is fixedly connected to the back side of the machine body 1. The surface of the separation seat 204 is fixedly connected to the inner cavity of the machine body 1. A connecting rod 211 is fixedly connected to the output end of the motor 201. A separation paddle 210 is fixedly connected to the surface of the connecting rod 211. The surface of the separation paddle 210 is rotatably connected to the inner cavity of the separation seat 204. The motor 201 is started by an external power supply. The motor 201 drives the connecting rod 211 to rotate. The rotation of the connecting rod 211 drives the separation paddle 210 to rotate inside the separation seat 204, breaking up the seeds that enter the separation seat 204 and preventing the seeds from clumping and clogging the sieve holes.

[0028] Reference Figure 5 , Figure 6 and Figure 7 The inner cavity of the separating seat 204 is slidably connected with a separating plate 214. There are three separating plates 214 arranged in multiple rows. By setting the separating plates 214, the seeds after being dispersed by the separating paddle 210 are separated a second time, so that the seeds can move through the space defined by the separating plates 214, thereby further reducing the phenomenon of seed clumping.

[0029] Reference Figure 5 , Figure 6 and Figure 7 The front and back sides of the separating seat 204 are provided with moving grooves 208. A connecting plate 213 is slidably connected to the inner cavity of the moving groove 208. One side of the connecting plate 213 is fixedly connected to the surface of the separating plate 214, and the other side of the separating plate 214 is fixedly connected to the connecting frame 207. A protrusion 209 is fixedly connected to the top of the connecting frame 207. The top of the protrusion 209 contacts a protruding plate 206. The inner cavity of the protruding plate 206 is fixedly connected to the surface of the connecting rod 211. Due to the setting of the protruding plate 206, it will intermittently contact the top of the protrusion 209 during rotation. The protruding plate 206 pushes the protrusion 209 to move downward. The movement of the protrusion 209 drives the connecting frame 207 to move. The movement of the connecting frame 207 drives the connecting plate 213 to move. The movement of the connecting plate 213 drives the separating plate 214 to move. This allows the separating plate 214 to move inside the separating seat 204, preventing seeds from accumulating on the surface of the separating plate 214.

[0030] Reference Figure 4, Figure 5 Diagram and Figure 7 Movable grooves 205 are provided on the front and back sides of the inner cavity of the body 1. The inner cavity of the movable groove 205 is fixedly connected to the surface of the connecting frame 207. A positioning rod 212 is fixedly connected to the inner cavity of the movable groove 205. The surface of the positioning rod 212 is slidably connected to the inner cavity of the protrusion plate 206. The positioning rod 212 guides the movement of the connecting frame 207, keeps the connecting frame 207 vertical, avoids the position of the connecting frame 207 from shifting during the movement, and improves the stability of the connecting frame 207 during the movement.

[0031] Reference Figure 4 , Figure 5 Diagram and Figure 7 Springs 215 are fixedly connected to the four corners of the bottom of the connecting frame 207. One end of the spring 215 is fixedly connected to the bottom of the inner cavity of the movable groove 205. The inner cavity of the spring 215 is sleeved on the surface of the positioning rod 212. The spring 215 supports the position of the connecting frame 207. When the connecting frame 207 is under force and moves downward, the spring 215 is compressed and contracts. When the connecting frame 207 is not under force, the spring 215 restores its deformation and pushes the connecting frame 207 upward, thereby driving the connecting frame 207 to quickly reset. This makes it easy for the connecting frame 207 to move downward again, so that the separating plate 214 can swing up and down inside the separating seat 204, improving the separation effect of seeds.

[0032] Reference Figure 2 and Figure 3 A drying chamber 202 is fixedly installed on the top of the back side of the machine body 1. A ventilation slot 203 is opened on the back side of the machine body 1. The inner cavity of the drying chamber 202 is connected to the inner cavity of the machine body 1. The drying chamber 202 consists of an electric heating tube, a fan, a temperature detector, and a temperature controller. The temperature controller is started by an external power supply, which drives the electric heating tube to heat up. The fan draws in outside air from below, heats it through the electric heating tube, and then delivers it into the ventilation slot 203. After passing through the ventilation slot 203, the air is delivered into the interior of the machine body 1 and comes into contact with the surface of the seeds, reducing the moisture on the seed surface and reducing the occurrence of seed clumping. While removing moisture from the seed surface, the temperature detector monitors the temperature inside the machine body 1 in real time to avoid abnormal temperature that could render the seeds unusable. The drying chamber 202 described above is existing technology and will not be described in detail here.

[0033] Reference Figure 1 , Figure 2 and Figure 3The top right side of the machine body 1 has a first discharge port 8. A collection box 7 is fixedly installed on the top right side of the machine body 1. A discharge plate 9 is fixedly installed on the top right side of the inner cavity of the machine body 1. With the setting of the discharge plate 9, after the seeds pass through the top of the guide plate 11, large foreign objects will move to the top of the discharge plate 9 under the action of inertia, and be collected into the inside of the collection box 7 by the guide of the discharge plate 9, so as to prevent foreign objects from falling to the ground and affecting the surrounding environment.

[0034] Working Principle: First, the seeds to be cleaned and screened are fed into the machine body 1 through the inlet 3. After entering the machine body 1, the seeds roll on top of the guide plate 11 because the screen 5, discharge plate 9, and guide plate 11 are all inclined. When the seeds roll to one end of the guide plate 11, the inertia of large particles between the seeds is greater than that of the seeds themselves, causing the seeds to fall into the separator 204 for secondary screening. Large particles fall to the top of the discharge plate 9 due to inertia and are then guided by the discharge plate 9 to fall into the collection box 7 for collection. Seeds that have undergone the first screening fall to the top of the screen 5 and continue rolling, filtering out small particles through the screen 5. Finally, the screened seeds are discharged to the outside through the second discharge port 10 for collection. When the seeds pass through the guide plate 11, the drying chamber 202 is started by an external power supply. The drying chamber 202 blows the hot air generated during the operation onto the surface of the seeds, reducing the moisture on the seed surface and reducing seed caking. In the event of seed clumping, when seeds enter the separator 204, the motor 201 is started by an external power source. The motor 201 drives the connecting rod 211 to rotate, which in turn drives the separating paddle 210 to rotate inside the separator 204, breaking up the seeds. The seeds broken up by the separating paddle 210 will then contact the surface of the separating plate 214, further separating the seeds. During the rotation of the connecting rod 211, the protruding plate 206 will rotate synchronously. During the rotation of the protruding plate 206, it will intermittently contact the protrusion 209. The rotation of the protruding plate 206 pushes the protrusion 209 downward, which in turn drives the connecting frame 207 to move. The movement of the connecting frame 207 drives the connecting plate 213 to move, which in turn causes the separating plate 214 to move up and down inside the separator 204, effectively separating the seeds and preventing seed clumping from blocking the sieve holes.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
