Technical Field

[0001] This invention relates to the field of grain crop processing, and more particularly to a grain crop particle screening device for agricultural processing. Background Technology

[0002] In the use of existing vibrating screening machines, the grain morphology of different crops varies greatly, and different varieties of the same crop also have different requirements for screen size. The screens of existing equipment are mostly fixed structures, and replacing the screens requires stopping the machine for disassembly, which is cumbersome and time-consuming, and the adaptability is obviously limited. At the same time, in the existing air separator structure, the grain grains fall in bundles, the grain grain dispersion effect is poor, and the airflow has difficulty penetrating the dense grain pile.

[0003] Furthermore, when processing grain particles with many impurities using existing technologies, the grain particles tend to accumulate in the screening channel, resulting in incomplete impurity removal and affecting processing efficiency. At the same time, if the equipment is not cleaned in time when it is idle, dust and other impurities can easily enter the screening channel, increasing cleaning costs. Summary of the Invention

[0004] To overcome the shortcomings of single-screen screening, poor adaptability, poor dispersion of grain particles falling in bundles, and the easy intrusion of dust and other impurities into the screening channel if the equipment is not cleaned in time when idle, this invention provides a grain particle screening device for agricultural processing.

The first and second connecting plates are slidably connected to adjacent square frames. Each square frame has a connecting shaft on its lower side. Each connecting shaft has a control plate installed on its right side. Each connecting shaft has a third screening plate installed on its left side. All first connecting plates are connected to adjacent control plates. All second connecting plates are connected to adjacent third screening plates. An exhaust plate is installed on both the front and rear sides of the screen box. An air vent is located between every two square frames and is connected to the exhaust plate.

[0006] Furthermore, the vibration unit includes elastic elements and a vibration motor; a support frame is provided on both sides of the screen box; several elastic elements are installed on the front and rear sides of the support frame; the screen box is fixed by all the elastic elements; a vibration motor is fixedly connected to the screen box; the vibration motor can drive the screen box to vibrate.

[0007] Furthermore, both the first and second inclined plates are located above the adjusting plate.

[0008] Furthermore, the first inclined plate and the second inclined plate are symmetrically arranged, and their inclination angles are equal.

[0009] Furthermore, the square frame is hollow.

[0010] Furthermore, a sliding groove is provided on the inner wall of the front side of the square frame; both the first connecting plate and the second connecting plate are slidably connected to the sliding groove.

[0011] Furthermore, the first control shaft drives the control plate to rotate, thereby controlling the size of the opening of the square frame.

[0012] Furthermore, it also includes a cleanup and protection assembly, which includes a fixed shaft and a distribution plate; a fixed shaft is connected to the left side of each control plate; another fixed shaft is connected to the right side of each third screening plate; and three distribution plates for dispersing grain crop particles are installed on each fixed shaft via torsion springs.

[0013] Furthermore, the material distribution plate is fan-shaped, and the center of the fan-shaped plate points towards the control plate.

[0014] Furthermore, the material distribution plates on the left and right sides of the square frame are staggered, and the material distribution plates on adjacent square frames are also staggered, which can be combined to close the air vent between two square frames.

[0015] The present invention has the following advantages: The present invention realizes that by adjusting the angle of the first screening plate and the second screening plate, the size of the opening above the square frame can be changed, thereby adapting to the size of the material particles to be screened, so as to achieve the purpose of screening. At the same time, the control plate and the third screening plate will buffer and disperse the falling material, and the exhaust plate will sort and remove impurities from the grain crop particles through the air vents between the two square frames, thereby achieving the purpose of cleaning the grain crop particles.

[0016] By designing multiple distribution plates, the grain particles can be further dispersed. At the same time, the cross-cooperation of adjacent distribution plates can clear and protect the air vents between the two square frames, protect the impurity removal channel, reduce manual operation costs, and significantly improve the stability of the equipment.

The first control shaft 101 and the second control shaft 103 are rotatably connected; the first screening plate 106 and the second screening plate 110 are respectively located on the upper inner side of adjacent square frames 105, and the first screening plate 106 and the second screening plate 110 located in the same square frame 105 are symmetrically arranged; a first connecting plate 107 is installed on the front side of each first screening plate 106; a second connecting plate 111 is installed on the front side of each first screening plate 106; the first connecting plate 107 and the second connecting plate 111 are respectively slidably connected to the adjacent square frame 105; a connecting shaft 109 is provided on the lower side of each square frame 105; each connecting shaft 109 A control plate 108 is installed on the right side of each square frame 105, and the first control shaft 101 drives the control plate 108 to rotate, thereby controlling the opening size of the square frame 105. A third screening plate 112 is installed on the left side of each connecting shaft 109. The control plate 108 and the third screening plate 112 located on the same connecting shaft 109 are symmetrically arranged. All first connecting plates 107 are connected to the adjacent control plate 108 respectively. All second connecting plates 111 are connected to the adjacent third screening plate 112 respectively. An exhaust plate 113 is installed on the front and rear sides of the inside of the screening box 3. There is an air vent between every two square frames 105, and the air vent is connected to the exhaust plate 113.

[0021] The vibration unit includes an elastic element 2 and a vibration motor 4; a support frame 1 is provided on both sides of the screen box 3; two elastic elements 2 are installed on the front and rear sides of the support frame 1, and the elastic element 2 is a spring; the screen box 3 is fixed by all the elastic elements 2; a vibration motor 4 is fixedly connected to the screen box 3; the vibration motor 4 can drive the screen box 3 to vibrate.

[0022] A sliding groove is provided on the inner front wall of the square frame 105; the first connecting plate 107 and the second connecting plate 111 are both slidably connected to the sliding groove, thereby realizing the up and down sliding of the first connecting plate 107 and the second connecting plate 111.

[0023] Vibrating screens are suitable for most common grain crops. The key is that the grains must meet the conditions that can be distinguished by physical characteristics. For example, wheat, rice, corn, soybeans, and rapeseed grains have significant differences in size, specific gravity, and shape (such as full and empty wheat grains, and soybeans of different sizes). The hardness and size of the grains must be compatible with the screen (to avoid clogging or leakage). Then, grading or impurity removal can be achieved through screening. In the use of existing vibrating screens, the grain morphology of different crops varies greatly, and different varieties of the same crop also have different requirements for screen aperture size. The screens of existing equipment are mostly fixed structures. Replacing the screen requires stopping the machine for disassembly, which is cumbersome and time-consuming, and the adaptability is obviously limited. In the existing air separator structure, the bundled grain materials fall, the material dispersion effect is poor, and the airflow has difficulty penetrating the dense grain pile.

[0024] To address the aforementioned issues, when different grain particles need to be screened, the drive unit 5 is activated. The drive unit 5 then pushes the adjusting plate 6 upwards to a suitable position. At this time, the adjusting plate 6 presses against several first inclined plates 102 and second inclined plates 104, adjusting the tilt angles of these plates. Simultaneously, each first inclined plate 102 and second inclined plate 104 drives the first control shaft 101 and the second control shaft 103 to rotate. Subsequently, the first screening plate 106 and the second screening plate 110 will also rotate by the same angle. This allows control over the size of the opening above the square frame 105, adapting to the size of the grain particles to be screened. After the first screening plate 106 and the second screening plate 110 rotate upwards by a fixed angle, they will drive the first connecting plate 107 and the second connecting plate 111, which are slidably connected to them, upwards. After moving a certain distance, the control plate 108 and the third screening plate 112 will also rotate upward at a fixed angle, thereby adjusting the size of the opening below the square frame 105, so that the screened grain particles can flow out of the square frame 105. The control plate 108 and the third screening plate 112 will buffer and disperse the falling grain particles. At this time, the exhaust plate 113 starts to start, and through the air vent between the two square frames 105, the grain particles are air-separated to remove impurities. This can remove impurities mixed in with the grain particles and achieve the purpose of cleaning the grain particles. Compared with the existing air separation technology, this method can effectively disperse the particles and improve the impurity removal effect. At the same time, since the air separation channel opening is designed to be close to the particles, the air separation distance can be effectively shortened and the air separation efficiency can be improved.

[0025] Example 2 Based on Example 1, such as Figures 7-9 As shown, it also includes a cleanroom protection assembly, which includes a fixed shaft 201 and a distribution plate 202; each control plate 108 is connected to a fixed shaft 201 on its left side; each third screening plate 112 is connected to another fixed shaft 201 on its right side; each fixed shaft 201 is equipped with three distribution plates 202 by torsion springs, and the distribution plates 202 on the left and right sides of the square frame 105 are staggered; the distribution plates 202 can intersect with the distribution plates 202 installed on another square frame 105 to close the air vent between the two square frames 105.

[0026] The distribution plate 202 is fan-shaped, and the center of the fan points to the control plate 108; the distribution plate 202 can disperse the falling grain particles and prevent them from piling up together.

[0027] Furthermore, in the existing technology, when processing grain particles containing a lot of impurities, the grain particles tend to accumulate in the screening channel, which prevents the airflow from penetrating evenly and the impurities from being separated completely. This requires multiple rework processes, affecting processing efficiency. When the equipment is idle, if it is not cleaned in time, dust and other impurities can easily enter the screening channel, which can easily contaminate the grain particles the next time it is used, increasing cleaning costs.

[0028] To address the aforementioned issues, after the grain grains fall and impact the control plate 108 and the third screening plate 112, the separating plate 202 can further disperse the grain grains, preventing them from accumulating. Simultaneously, after impurities mixed in with the grain grains are separated, the exhaust plate 113 will extract these impurities through the vents between the two square frames 105, further cleaning the grain grains. When the square frames 105 are not needed, the adjusting plate 6 is raised to below the first control shaft 101. At this time, the first inclined plate 102 and the second inclined plate 104 will be on a horizontal plane, and the first screening plate 106 and the second screening plate 110 will also... When the square frame 105 is in a horizontal position, it can be enclosed to prevent impurities from entering the square frame 105 when it is not in use, thereby achieving the purpose of protecting the square frame 105. At this time, the control plate 108 and the third screening plate 112 will also be adjusted to a horizontal position. As the control plate 108 and the third screening plate 112 rotate upward, since each distribution plate 202 is installed in a staggered manner with the other distribution plate 202 on its adjacent side, the distribution plates 202 on both sides will cross each other, which can clear the air vent between the two square frames 105, and at the same time, close the air vent. As shown in the figure, this can simplify idle management, reduce manual operation costs, and significantly improve the stability of the equipment.
