Description

Technical Field

[0001] This utility model relates to the field of soybean sorting technology, specifically to a soybean fine sorting and grain separating machine. Background Technology

[0002] In the food industry, soybeans of different sizes are suitable for different processing applications. For example, when making soy milk, tofu, and other soy products, soybeans of uniform size are needed to ensure consistent product quality and taste. When making fermented soy products such as fermented black beans, there are also specific requirements for soybean particle size to ensure a uniform and thorough fermentation process. Soybean sorting and separating machines can meet the needs of food processing enterprises for the fine sorting of soybean raw materials, improving product quality and production efficiency.

[0003] Existing technology uses disc centrifugation to separate soybeans of different diameters. Larger soybeans, due to their greater momentum and energy, can achieve greater speed under continuous centrifugal force, thus being propelled further. Smaller soybeans, with less inertia, are easier to initiate movement under the same centrifugal force, but because of their smaller mass, they acquire relatively less momentum and energy, resulting in a lower speed and shorter distance of propulsion. This process achieves the separation of the soybeans.

[0004] However, during centrifugation, some of the larger beans will push the smaller beans, resulting in a uniform centrifugation distance after being thrown, which reduces the accuracy of the bean separation. Utility Model Content

[0005] This invention addresses the technical problem that during centrifugation, some large-mass soybeans push smaller-mass soybeans, resulting in uniform centrifugation distances after being thrown, thus reducing the precision of soybean separation. Therefore, this invention provides a soybean selection and separation machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soybean sorting and grain separating machine, comprising: a hopper, the hopper being connected to a feed pipe, the feed pipe being connected to the top wall of the sorting chamber, a limiting column being concentrically arranged inside the feed pipe, a gap being left between the limiting column and the inner wall of the feed pipe, the gap being larger than the maximum diameter of the soybean, the lower end of the limiting column being connected to a turntable, the lower surface of the turntable being connected to a rotating shaft, the rotating shaft being rotatably connected to the bottom wall of the sorting chamber, and multiple centrifugal grooves being evenly distributed around the inner circumference of the turntable, each centrifugal groove being connected in layers with multiple sorting plates, the aperture of the sorting plates gradually decreasing from top to bottom.

[0007] Preferably, a spiral blade is provided in the gap between the limiting column and the inner wall of the feed pipe, and the spiral blade is connected to the limiting column.

[0008] Preferably, the bottom wall of the selection chamber is concentrically connected with multiple partition rings, and the multiple partition rings and the bottom wall of the selection chamber together form multiple storage spaces. The bottom wall of the selection chamber at each storage space is connected to a corresponding discharge pipe.

[0009] Preferably, the lower part of the rotating shaft is connected to multiple levers, and each storage space is equipped with a corresponding lever.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] Soybeans fall into the rotating centrifugal trough through the feed pipe. Under the restriction of the material limiting column, a large number of soybeans will not enter the trough at the same time. Under the centrifugal force, the soybeans roll along the sorting plate. Smaller diameter soybeans pass through the holes of the sorting plate and roll along the next sorting plate. In this way, soybeans of different diameters roll along different tracks and are thrown over different distances, thus completing the sorting. Larger soybeans will not push smaller soybeans, which would reduce the sorting accuracy.

[0012] The spiral blades on the feed column push the beans forward, preventing blockage between the feed column and the inner wall of the feed pipe. Attached Figure Description

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.

[0018] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to a connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-3 This embodiment describes a soybean sorting and grain separating machine, comprising: a hopper 1, which is connected to a feed pipe 2, which is connected to the top wall of a sorting chamber 3; a limiting column 4 is concentrically arranged inside the feed pipe 2, with a gap between the limiting column 4 and the inner wall of the feed pipe 2, the gap being larger than the maximum diameter of the soybean; the lower end of the limiting column 4 is connected to a turntable 5, the lower surface of the turntable 5 is connected to a rotating shaft 6, and the rotating shaft 6 is rotatably connected to the bottom wall of the sorting chamber 3; multiple centrifugal grooves 7 are evenly distributed around the inner circumference of the turntable 5, and multiple sorting plates 8 are connected in layers in each centrifugal groove 7, with the aperture of the sorting plates 8 gradually decreasing from top to bottom.

[0021] Soybeans fall into the centrifugal trough 7 of the turntable 5 through the hopper 1 and the feed pipe 2. Under the restriction of the limiting column 4, a large number of soybeans will not enter the trough at the same time. The power of the rotating shaft 6 is turned on, and the rotating shaft 6 drives the turntable 5 to rotate. Under the centrifugal action, the soybeans roll along the sorting plate 8. The soybeans with smaller diameters pass through the holes of the sorting plate 8 and roll along the lower sorting plate 8. In this way, soybeans of different diameters roll along different tracks and are thrown over different distances, thus completing the sorting. There will be no situation where large-mass soybeans push small-mass soybeans, which would reduce the sorting accuracy.

[0022] A spiral blade 10 is provided in the gap between the limiting column 4 and the inner wall of the feed pipe 2, and the spiral blade 10 is connected to the limiting column 4.

[0023] The spiral blade 10 on the limiting column 4 pushes the beans and avoids clogging of the gap between the limiting column 4 and the inner wall of the feed pipe 2.

[0024] Multiple partition rings 11 are concentrically connected to the bottom wall of the selection chamber 3. The multiple partition rings 11 and the bottom wall of the selection chamber 3 together form multiple storage spaces. The bottom wall of the selection chamber 3 at each storage space is connected to a corresponding discharge pipe 12.

[0025] The centrifuged soybeans fall into the storage space formed by different separating rings 11 and are discharged through the discharge pipe 12.

[0026] The lower part of the rotating shaft 6 is connected to multiple levers 13, and each storage space is equipped with a corresponding lever 13.

[0027] The rotating shaft 6 drives the paddle plate 13 to rotate, and the rotation of the paddle plate 13 pushes the beans to the discharge pipe 12 for discharge, which facilitates discharge.
