Description

Technical Field

[0001] This utility model relates to the field of seed processing technology, specifically to a seed threshing and air-separation device. Background Technology

[0002] In agricultural production, seed processing is a crucial step in ensuring seed quality and increasing crop yield. Traditional seed processing mainly relies on manual methods such as threshing and crushing, combined with natural wind or simple sieves for cleaning. However, with the increasing demands for seed quality in modern agriculture, mechanized and automated seed processing equipment has emerged.

[0003] The existing technology has the following problems: corn is usually threshed by beating, which can easily cause the corn kernels to be broken, thereby reducing the integrity of threshing and affecting the threshing effect.

[0004] Therefore, this utility model provides a seed threshing and air separation device to solve the above problems. Utility Model Content

[0005] This invention provides a seed threshing and air-separation device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a fixed box and a threshing mechanism assembled inside the fixed box, wherein a top cover is fixedly connected to the top of the fixed box and a protective shell is fixedly connected to one side of the fixed box;

[0007] The threshing mechanism includes a servo motor fixedly installed on the inner wall of the protective shell, two rollers mounted inside the fixed box, and cylinders fixedly connected to both ends of the two rollers. One end of each cylinder passes through the fixed box and is fixedly connected to two gears that mesh with each other. Two spiral columns that conform to the surface of each roller are fixedly connected to the surface of the rollers. The output end of the servo motor is fixedly connected to the surface of one gear. A threaded rod is threadedly connected to the top of the top cover, and one end of the threaded rod is rotatably connected to an arc-shaped plate through a bearing.

[0008] As a preferred technical solution of this application, two telescopic rods are fixedly connected to the top two sides of the arc-shaped plate, the tops of the two telescopic rods are fixedly connected to the inner top wall of the top cover, and multiple curtains are fixedly connected to one side of the top cover.

[0009] As a preferred technical solution of this application, a guide plate is fixedly connected to one end of the arc-shaped plate, and a pressure plate is fixedly connected to the bottom of the arc-shaped plate.

[0010] As a preferred technical solution of this application, a rectangular groove is provided on one side of the surface of the fixing box, a filter screen is fixedly connected to one side of the inner wall of the rectangular groove, and an air collecting block is fixedly connected to the other side of the inner wall of the rectangular groove.

[0011] As a preferred technical solution of this application, a duct is connected through one side of the air collecting block, one end of the duct is connected to an exhaust fan, and the exhaust fan is fixedly installed on the other side of the surface of the fixed box.

[0012] As a preferred technical solution of this application, two fixed columns are rotatably connected to the other side of the inner wall of the fixed box, a sieve plate is fixedly connected to one side of the two fixed columns, and one end of the fixed column passes through the fixed box and is fixedly connected to a movable plate.

[0013] As a preferred technical solution of this application, a guide rod is rotatably connected to one side of the surface of the movable plate, and the other end of the guide rod is rotatably connected to the surface of the gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By activating the threshing mechanism, a servo motor is started, driving two gears to rotate relative to each other. Corn is placed between two gear-driven rollers. The corn kernels on the surface of the corn are detached due to friction from the spiral columns on the rollers. Simultaneously, the corn is held in place by an arc-shaped plate, further increasing the friction of the spiral columns and effectively reducing the amount of corn kernels being crushed, thus improving the integrity of the threshing process. Furthermore, the guide rod on the gear surface drives one end of a movable plate to move up and down around a fixed column, causing the screen plate to sway left and right. This allows larger pieces of residue to remain on the screen plate, while the corn kernels fall smoothly, thereby improving the cleanliness of the threshed corn and further enhancing the practicality of the device.

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] This utility model provides, for example Figure 1-5 The seed threshing and air-separating device shown includes a fixed box 1 and a threshing mechanism 2 assembled inside the fixed box 1. A top cover 3 is fixedly connected to the top of the fixed box 1, and a protective shell 4 is fixedly connected to one side of the fixed box 1. The threshing mechanism 2 includes a servo motor 201 fixedly installed on the inner wall of the protective shell 4, two rollers 202 mounted inside the fixed box 1, and cylinders 203 fixedly connected to both ends of the two rollers 202. One end of each cylinder 203 passes through the fixed box 1 and is fixedly connected to two gears 204. The two gears 204 mesh with each other. Two spiral columns 205 that conform to the surface of the rollers 202 are fixedly connected to the surface of each roller 202. The output end of the servo motor 201 is fixedly connected to the surface of one gear 204. A threaded rod 206 is threadedly connected to the top of the top cover 3. One end of the threaded rod 206 is rotatably connected to an arc plate 207 through a bearing.

[0024] Two telescopic rods 5 are fixedly connected to the top two sides of the arc plate 207. The top of the two telescopic rods 5 is fixedly connected to the inner top wall of the top cover 3. Multiple curtains are fixedly connected to one side of the top cover 3.

[0025] A guide plate 6 is fixedly connected to one end of the arc plate 207, and a pressure plate 7 is fixedly connected to the bottom of the arc plate 207.

[0026] A rectangular groove is provided on one side of the surface of the fixed box 1. A filter screen 8 is fixedly connected to one side of the inner wall of the rectangular groove, and an air collecting block 9 is fixedly connected to the other side of the inner wall of the rectangular groove.

[0027] A duct 10 is connected through one side of the air collecting block 9, and one end of the duct 10 is connected to the exhaust fan 11. The exhaust fan 11 is fixedly installed on the other side of the surface of the fixed box 1.

[0028] Two fixed columns 12 are rotatably connected to the other side of the inner wall of the fixed box 1. A sieve plate 13 is fixedly connected to one side of the two fixed columns 12. One end of the fixed column 12 passes through the fixed box 1 and is fixedly connected to a movable plate 14.

[0030] The working principle of a seed threshing and air-separating device based on an embodiment is as follows: A servo motor 201 is started, driving two gears 204 to rotate relative to each other. Corn is placed between two rollers 202 driven by the gears 204. Then, the threaded rod 206 is rotated to lower the arc-shaped plate 207 and make it fit against the corn. The pressure plate 7 at the bottom of the arc-shaped plate 207 is M-shaped, which better holds the corn, allowing the corn to be more fully rubbed by the spiral column 205, thereby performing the threshing process.

[0031] Turn on the exhaust fan 11 so that it can suck out the dust from the fixed box 1 through the duct 10 from the air collecting block 9. The filter screen 8 can prevent the corn kernels from being sucked out. In addition, the guide rod 15 on the surface of the gear 204 drives one end of the movable plate 14 to move up and down around the fixed column 12, causing the screen plate 13 to sway up and down on both sides. In this way, larger pieces of residue will stay on the screen plate 13, while the corn kernels will fall off smoothly.
