Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a tiger nut particle size grading and screening device. Background Technology

[0002] Oilseed mallow, also known as oilseed grass, is nicknamed "underground walnut" due to its plump, round shape and rich oil and nutrients. As a new type of economic crop that integrates the functions of grain, oil, and feed, its seeds are rich in high-quality vegetable oil with a high proportion of unsaturated fatty acids and a fragrant taste. It can be directly processed into edible oil or ground into powder for making pastries, porridge, etc. It combines the satiety of grains with the nutritional density of nuts. In the industrial field, the oil cake after pressing is rich in protein and is a high-quality feed raw material, which can provide efficient nutritional supplements for animal husbandry. This forms a circular industrial chain of "planting-oil pressing-feed". In addition, oilseed mallow is highly adaptable, drought-resistant and tolerant of poor soil, has low soil requirements, is easy to plant and manage, and has stable yields. It also has considerable advantages in optimizing planting structure and improving land utilization.

[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 protection scope of the present utility model.

[0025] This utility model provides a tiger nut size grading and screening device, including a main body 1. A fixing plate 2 is installed on the left side of the main body 1. A dust collection box 3 is installed on the upper surface of the fixing plate 2. The dust collection box 3 has an installation groove 4 inside. Multiple telescopic rods 5 are installed inside the installation groove 4. A first spring 6 is sleeved on the outer surface of each telescopic rod 5. A fixing frame 7 is installed at the top of the multiple telescopic rods 5. A filter plate 8 is snapped into the inside of the fixing frame 7. A flexible hose 9 is connected to the upper surface of the dust collection box 3. An exhaust fan 10 and a feed hopper 25 are installed on the upper surface of the main body 1. The end of the flexible hose 9 away from the dust collection box 3 is connected to the output end of the exhaust fan 10. A connecting pipe 1 is connected to the input end of the exhaust fan 10. 1. The end of the connecting pipe 11 away from the exhaust fan 10 passes through the main body 1 of the device and is connected to the connecting plate 12. Multiple suction heads 13 are installed on the bottom surface of the connecting plate 12. The upper surface of the dust collection box 3 is connected to the output end of the exhaust fan 10 through the hose 9. The input end of the exhaust fan 10 passes through the main body 1 of the device and is connected to the connecting plate 12 through the connecting pipe 11. The multiple suction heads 13 on the bottom surface of the connecting plate 12 can absorb the dust and impurities raised during screening. When the exhaust fan 10 is started, the dust and impurities enter the dust collection box 3 through the suction heads 13, the connecting pipe 11, the exhaust fan 10 and the hose 9. The filter plate 8 filters the impurities and the dust collection box 3 collects them. When cleaning or replacing the filter plate 8, it can be easily operated with the help of the telescopic rod 5, the first spring 6 and the fixing frame 7.

[0026] The device body 1 has a first screen frame 14 and a second screen frame 15 inside. The device body 1 also has two sets of electric push rods 16 and two sets of damping rods 17 installed inside. The outer surface of each set of damping rods 17 is fitted with a second spring 18.

[0027] The output end of one set of electric push rods 16 and the telescopic end of one set of damping rods 17 are connected to the outer surface of the first screen frame 14, and the output end of the other set of electric push rods 16 and the telescopic end of the other set of damping rods 17 are connected to the outer surface of the second screen frame 15. When the two sets of electric push rods 16 are activated, their telescopic ends drive the first screen frame 14 and the second screen frame 15 to move. The damping rods 17 and the second spring 18 play a buffering role to ensure stable vibration screening of the screen frames. The aperture of the first screen frame 14 is larger than that of the second screen frame 15, which facilitates grading and screening.

[0028] Electric slide rails 19 are installed inside the first sieve frame 14 and the second sieve frame 15. A sliding seat 20 is slidably connected to the outer surface of each electric slide rail 19. A push plate 21 is connected to the outer surface of each sliding seat 20. When the screening is completed, the electric slide rail 19 is started, which drives the sliding seat 20 to move, thereby causing the push plate 21 to slide inside the sieve frame. This pushes the screened tiger nuts in the sieve frame to the discharge port, making it convenient to collect the tiger nuts.

[0029] The device body 1 has a collection box 22 inside. Two sliders 23 are installed on the bottom surface of the dust collection box 3. Two grooves 24 are opened on the inner bottom wall of the device body 1. The outer surface of each slider 23 is slidably connected to the inside of the groove 24.

[0030] Four threaded cylinders 26 are installed on the bottom surface of the main body 1. Each threaded cylinder 26 is threaded with a support leg 27 inside. A controller 28 is installed on the left side of the main body 1.

[0031] Working principle: First, tiger nuts enter the main body 1 of the device through the feed hopper 25. After the device is turned on by the controller 28, two sets of electric push rods 16 are activated, driving the first screen frame 14 and the second screen frame 15 to reciprocate. At the same time, the damping rod 17 and the second spring 18 work together to buffer and reduce the vibration and impact during the movement of the screen frames. Under the vibration of the first screen frame 14 and the second screen frame 15, the tiger nuts are graded and screened according to their particle size. Smaller tiger nuts fall through the sieve holes of the first screen frame 14 into the second screen frame 15. After further screening, the smaller diameter tiger nuts finally fall into the collection box 22 below. During the screening process, the exhaust fan 10 is started simultaneously, generating negative pressure through the connecting pipe 11 and multiple dust suction heads 13 to suck up the dust and impurities raised during screening. The impurities are introduced into the dust collection box 3 via the hose 9. The filter plate 8 in the dust collection box 3 filters the impurities, and the filtered impurities are retained in the dust collection box 3 for centralized collection. When it is necessary to clean or replace the filter plate 8, external force is applied to the fixing frame 7, the telescopic rod 5 retracts and the first spring 6 is compressed, so the filter plate 8 can be removed. After cleaning or replacement, the external force is released, the first spring 6 returns to its original position, causing the telescopic rod 5 to extend, and the fixing frame 7 to re-securely lock the filter plate 8. In addition, the electric slide rail 19 can drive the sliding seat 20 and the push plate 21 to move, which makes it easy to push the tiger nuts in the screen frame out of the movable door of the screen frame, improving the screening efficiency. The collection box 22 slides in the slide groove 24 through the slider 23, which is convenient for removal and cleaning. Rotating the support leg 27 can adjust the height of the threaded cylinder 26 to achieve stable placement of the device.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
