Description

Technical Field

[0001] This utility model relates to the field of grain and oil processing technology, and in particular to a high-efficiency screening and sorting device for grain and oil processing raw materials. Background Technology

[0002] High-efficiency screening and sorting equipment for grain and oil processing raw materials is an advanced mechanical device specifically designed for the automated cleaning, grading, and classification of agricultural products such as grains and oilseeds. It uses various technologies such as vibrating screens, gravity destoners, color sorters, and magnetic separators to efficiently remove impurities from raw materials and accurately sort them according to particle size, density, color, or composition. This type of equipment adopts PLC control, AI image recognition, or near-infrared sensing technology, which significantly improves processing efficiency and product quality while reducing labor costs and raw material losses. It is widely used in grain and oil processing plants, seed treatment centers, and food production lines, and is one of the core equipment for modern agricultural product processing.

[0003] Existing grain and oil raw material screening devices only have screening functions and do not integrate a peeling structure, resulting in obvious defects in actual production. Due to the lack of integrated design, operators must first send the raw materials to a separate peeling device for processing, and then transfer them to the screening machine for grading. This segmented operation method not only increases equipment investment and space occupation, but also leads to production process interruption, increased energy consumption and labor costs, which seriously restricts the improvement of production efficiency and product quality.

[0004] Therefore, in view of the problem that the existing grain and oil raw material screening devices only have screening functions and do not integrate peeling structures, and cannot peel the raw materials before screening, resulting in low production efficiency, a high-efficiency screening and sorting device for grain and oil processing raw materials can be designed. Utility Model Content

[0005] In order to overcome the problem that existing grain and oil raw material screening devices only have screening functions and do not integrate a peeling structure, they cannot peel the raw materials before screening, resulting in low production efficiency.

[0006] The technical solution of this utility model is as follows: a high-efficiency screening and sorting device for grain and oil processing raw materials, including an installation frame; a drive motor is installed inside the installation frame, the output end of the drive motor is connected to a transmission disc, two connecting rods are rotatably connected inside the installation frame, a screen is rotatably connected between the two connecting rods, two bearing seats are installed on the right side of the installation frame, a rotating shaft is connected between the two bearing seats, a transmission disc is installed at the front end of the rotating shaft, a belt is sleeved on the outer side of the transmission disc and the transmission disc, an installation disc is installed on the rear side of the rotating shaft, a rocker arm is installed on the outer side of the installation disc, the rocker arm is rotatably connected to the screen, a feeding mechanism is installed at the top of the installation frame, and the installation frame... Two mounting seats are installed at the top, and two fine pressure rollers are rotatably connected between the two mounting seats. Two coarse pressure rollers are also rotatably connected between the two mounting seats. Gear 1 is installed at both the front and rear ends of the lower fine pressure roller, and gear 2 is installed at both the front and rear ends of the upper fine pressure roller. Gear 1 and gear 2 mesh with each other. Gear 3 is installed at both the front and rear ends of the upper coarse pressure roller, and gear 4 is installed at both the front and rear ends of the lower coarse pressure roller. Gear 2 and gear 3 mesh with each other, and gear 1 and gear 4 mesh with each other. A transmission disc 3 is installed on the front gear 1, and a transmission disc 4 is installed at the output end of the drive motor. A belt 2 is sleeved on the outer side of the transmission discs 3 and 4. A material guiding mechanism is set on the top right side of the mounting frame.

[0007] Preferably, by setting a drive motor, during operation, its output end drives the first transmission disc to rotate. The first transmission disc, linked with the first belt, drives the second transmission disc to rotate, thereby causing the rotating shaft to drive the mounting disc to rotate. When the mounting disc rotates, it drives the rocker arm to rotate, so that the screen can shake back and forth with the cooperation of the connecting rod. During operation, the drive motor can also drive the fourth transmission disc to rotate. The fourth transmission disc, linked with the second belt, drives the third transmission disc to rotate, thereby driving the first gear to rotate. The first gear, through cooperation with the second, third, and fourth gears, can drive the two coarse pressure rollers and the two fine pressure rollers to rotate in opposite directions. When the raw material passes between the coarse and fine pressure rollers, it will be crushed and peeled. This solves the problem that the existing grain and oil raw material screening device only has a screening function and does not integrate a peeling structure, so it cannot peel the raw material before screening, resulting in low production efficiency.

[0008] Preferably, the feeding mechanism includes a holding component and a guiding component, wherein the holding component is used to receive raw materials and the guiding component is used to separate the raw materials.

[0009] Preferably, the holding component includes positioning seats, springs, a tray, a vibrating motor, and a corrugated plate; four positioning seats are provided on the top of the mounting frame, springs are connected to the outside of the positioning seats, a tray is installed on the top of the springs, a vibrating motor is provided at the bottom of the tray, the vibrating motor is used to drive the tray to vibrate, and a corrugated plate is provided inside the tray.

[0010] Preferably, the guide assembly includes guide plates; multiple equally spaced guide plates are mounted on the top of the wave plate.

[0011] Preferably, the material guiding mechanism includes an installation component and a flipping component, wherein the installation component is used to install the flipping component and the flipping component is used to change the material dropping direction.

[0012] Preferably, the mounting components include positioning bolts; two positioning bolts are installed inside the mounting frame.

[0013] Preferably, the flipping assembly includes a fixed plate and a sliding plate; the outer sides of the two positioning bolts are rotatably connected to the fixed plate, and the sliding plate is connected between the two fixed plates.

[0014] The beneficial effects of this utility model are:

[0015] By integrating a peeling structure into a vibrating screen and utilizing the screen's existing motor to drive the peeling device, the screening and peeling processes are efficiently coordinated. This innovative design significantly improves processing efficiency, allowing materials such as soybeans to be peeled before entering the screening process. This avoids the time and energy waste of the separate peeling step in traditional processes. At the same time, the integrated design reduces the equipment's footprint and lowers maintenance costs. The peeled material is more conducive to improving the subsequent screening accuracy, and the debris generated during the peeling process can be directly separated and discharged by the vibrating screen, ensuring the purity of the finished product.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment: a high-efficiency screening and sorting device for grain and oil processing raw materials, including an installation frame 1; a drive motor 2 is installed inside the installation frame 1, the output end of the drive motor 2 is connected to a transmission disc 3, two connecting rods 4 are rotatably connected inside the installation frame 1, a screen 5 is rotatably connected between the two connecting rods 4, two bearing seats 6 are installed on the right side of the installation frame 1, a rotating shaft 7 is connected between the two bearing seats 6, a transmission disc 8 is installed at the front end of the rotating shaft 7, and a belt 9 is sleeved on the outer side of the transmission disc 3 and the transmission disc 8. A mounting plate 10 is installed on the rear side of the 7. A rocker arm 11 is provided on the outer side of the mounting plate 10. The rocker arm 11 is rotatably connected to the screen 5. A feeding mechanism is provided on the top of the mounting frame 1. Two mounting seats 13 are installed on the top of the mounting frame 1. Two fine pressure rollers 14 are rotatably connected between the two mounting seats 13. Two coarse pressure rollers 15 are also rotatably connected between the two mounting seats 13. Gear 16 is installed at both the front and rear ends of the lower fine pressure roller 14. Gear 2 17 is provided at both the front and rear ends of the upper fine pressure roller 14. Gear 16 and gear 2 17 mesh with each other. Gear 3 18 is installed at both ends of the 5th gear, and gear 4 19 is installed at both ends of the lower coarse pressure roller 15. Gear 2 17 meshes with gear 3 18, and gear 1 16 meshes with gear 4 19. A transmission disc 3 20 is installed on the front gear 1 16, and a transmission disc 4 22 is installed at the output end of the drive motor 2. A belt 21 is sleeved on the outer side of the transmission disc 3 20 and the transmission disc 4 22. A material guiding mechanism is set on the top right side of the mounting frame 1. The drive motor 2 drives the two transmission systems simultaneously. On the one hand, the output end of the drive motor 2 drives the transmission disc 3 to rotate. The rotating shaft 7 drives the mounting plate 10 and rocker arm 11 to rotate via belt 9 and transmission disc 8. With the cooperation of connecting rod 4, the screen 5 shakes back and forth. On the other hand, the drive motor 2 drives the transmission disc 22 to rotate synchronously. Through belt 21, the transmission disc 20 drives gear 16 to rotate. Through the meshing transmission of gear 16, gear 27, gear 318 and gear 419, the two coarse pressure rollers 15 and the two fine pressure rollers 14 rotate in opposite directions. When the raw material passes between the rollers, it is crushed and peeled, realizing the coordinated operation of screen 5 shaking and roller pressing peeling.

[0025] Please see Figures 1-4In this embodiment, the feeding mechanism includes a holding component and a guiding component. The holding component is used to receive raw materials, and the guiding component is used to separate the raw materials. The holding component includes a positioning seat 121, a spring 122, a material tray 123, a vibration motor 124, and a corrugated plate 125. Four positioning seats 121 are provided on the top of the mounting frame 1. Springs 122 are connected to the outer sides of the positioning seats 121. A material tray 123 is mounted on the top of the springs 122, and a vibration motor 124 is provided at the bottom of the material tray 123. 24 is used to drive the material tray 123 to vibrate. The material tray 123 is equipped with a corrugated plate 125. By setting the vibration motor 124, the material tray 123 can be driven to vibrate under the cooperation of the spring 122 during operation. The material tray 123 is tilted so that the material can slowly move towards the coarse pressure roller 15 and the fine pressure roller 14. The guide assembly includes a guide plate 126. Multiple guide plates 126 are evenly distributed on the top of the corrugated plate 125. By setting the guide plates 126, the uniformity of material dispersion can be improved.

[0026] Please see Figure 5 and Figure 6 In this embodiment, the material guiding mechanism includes an installation component and a flipping component. The installation component is used to install the flipping component, and the flipping component is used to change the material dropping direction. The installation component includes positioning bolts 231. Two positioning bolts 231 are installed inside the installation frame 1. The flipping component includes a fixing plate 232 and a sliding plate 233. The fixing plate 232 is rotatably connected to the outside of the two positioning bolts 231. The sliding plate 233 is connected between the two fixing plates 232. By setting the fixing bolts, the angle of the fixing plate 232 and the sliding plate 233 can be fixed after tightening. Rotating the fixing plate 232 to the left can guide the peeled material to fall directly onto the screen 5, and rotating it to the right will directly pour the material onto the outside of the equipment.

[0027] During operation, the output of drive motor 2 simultaneously drives transmission disc 3 and transmission disc 4 22 to rotate. Transmission disc 3, through belt 9, drives transmission disc 8 to rotate, causing shaft 7 to rotate. Shaft 7 drives mounting disc 10 to rotate. Mounting disc 10 is rotatably connected to screen 5 through rocker arm 11, thus causing screen 5 to vibrate back and forth under the cooperation of connecting rod 4. At the same time, transmission disc 4 22, through belt 21, drives transmission disc 3 20 to rotate. Transmission disc 3 20 drives gear 16 to rotate. Gear 16, through meshing with gear 2 17, drives the upper fine pressure roller 14 to rotate. Gear 2 17, through meshing with gear 3 18, drives the upper coarse pressure roller 15 to rotate. Gear 3 18, through meshing with gear 4... Gear 19 meshes with gear 16, causing the lower coarse roller 15 to rotate. Gear 4 19 meshes with gear 16, causing the lower fine roller 14 to rotate. This causes both coarse rollers 15 and fine rollers 14 to rotate in opposite directions. The raw material moves in the material tray 123 by the vibration of spring 122 driven by vibrating motor 124. After being separated and dispersed by wave plate 125 and guide plate 126, it enters the coarse roller 15 and fine roller 14 for crushing and peeling. The peeled material is guided by slide plate 233 and falls into the vibrating screen 5 for screening. The angle of slide plate 233 is adjusted by positioning bolt 231 to change the direction of material falling. Rotating the fixed plate 232 to the left causes the material to fall onto the screen 5, while rotating it to the right causes it to be directly discharged from the equipment.

[0028] Through the above steps, by setting up drive motor 2, it achieves compound action through dual-path transmission during operation. In the main transmission path, drive motor 2 directly drives transmission disc 3 to rotate, and transmits power to transmission disc 8 via belt 9. Then, through rotating shaft 7, it drives mounting disc 10 to make circular motion. During the rotation, rocker arm 11 on mounting disc 10 cooperates with connecting rod 4 mechanism to convert into high-frequency back-and-forth shaking of screen 5. In the auxiliary transmission path, drive motor 2 simultaneously drives transmission disc 22 to rotate, and transmits power to transmission disc 20 via belt 21. Then, through the gear system composed of gear 16, gear 27, gear 318 and gear 419, it precisely controls the two coarse pressure rollers 15 and the two fine pressure rollers 14 to rotate in opposite directions. When the raw material passes through the crushing area between the coarse and fine roller groups, mechanical peeling is completed, ensuring the coordinated operation of screening and peeling processes. This solves the problem that the existing grain and oil raw material screening device only has screening function and does not integrate peeling structure, so it cannot peel the raw material before screening, resulting in low production efficiency.
