Description

Technical Field

[0001] This utility model belongs to the field of soybean product processing technology, and specifically relates to a soybean product screening structure. Background Technology

[0002] Soy products, as an important source of plant protein, occupy a central position in food processing and daily diets. These include not only common products like tofu and dried tofu, but also diverse products such as natto, which undergoes a special fermentation process. In the industrial production of soy products, the screening process is a crucial step in ensuring product quality. Its main function is to remove impurities from raw materials or to accurately grade the finished product according to particle size. Currently, most existing soybean product screening equipment adopts a single feeding channel structure or a basic vibrating screening device. In actual operation, due to the lack of a scientifically designed material dispersion and guidance mechanism, soybean product raw materials tend to fall in a concentrated manner when entering the screening area, resulting in extremely uneven distribution of granular materials on the screen plate surface. This uneven spreading state will cause excessive material pressure in local areas of the screen plate, which will greatly reduce the screen's transmission efficiency. Utility Model Content

[0003] In view of this, the present invention provides a soybean product screening structure, which can ensure that soybean products can be evenly spread on the screening plate through a dispersing component, ensuring the uniformity of feeding and distribution on the screening plate during soybean product screening, thereby improving the screening effect of soybean product particles and avoiding the problem of uneven screening caused by soybean product particles accumulating on the screening plate.

[0004] To solve the above-mentioned technical problems, this utility model provides a bean product screening structure, including a screening box for installing the screening mechanism. The feeding end of the screening box is provided with a dispersion component for dispersing bean products. The dispersion component includes multiple diversion hoppers evenly arranged at the upper end of the inner cavity of the screening box. Each of the multiple diversion hoppers is rotatably connected to a spiral conveying rod 1. The feeding end of the screening box is rotatably connected to a spiral conveying rod 2. The feeding end of the screening box is arranged in an inverted cone shape. The end of the spiral conveying rod 2 is provided with a transmission component for driving the rotation of all spiral conveying rods 1. This ensures that the bean products can be evenly spread onto the screening plate, ensuring the uniformity of feeding and distribution on the screening plate during bean product screening, thereby improving the screening effect of bean product particles and avoiding the problem of uneven screening caused by the accumulation of bean product particles on the screening plate. The diversion hoppers are all V-shaped, and the whole assembly of multiple diversion hoppers is offset at a 90-degree angle from the feed end of the screening box, which ensures that the material can be evenly conveyed into each diversion hopper.

[0005] Both the first and second spiral conveyors consist of a rod body and spiral blades at both ends of the rod body. The spiral directions of the spiral blades at both ends of the first and second spiral conveyors are set in opposite directions, thus realizing the conveying of bean products.

[0006] The dispersing assembly also includes a motor located at one end of the upper part of the screening box. The output shaft of the motor is fixedly connected to one end of the screw conveyor rod two, thus providing a driving source for the screw conveyor rod two.

[0007] The transmission component includes fixed blocks symmetrically arranged on one side of the upper end of the screening box. A worm gear is rotatably connected between the two fixed blocks. A worm wheel is provided at the end of the screw conveyor rod near the worm gear. All worm wheels are meshed with the worm gear, which can synchronously drive the screw conveyor rod to rotate.

[0008] The transmission components also include pulleys respectively located at one end of the screw conveyor and one end of the worm. The two pulleys are connected by a transmission belt, which enables rapid transmission of the worm.

[0009] The screening mechanism includes mounting blocks symmetrically arranged at the four corners of the screening box. Each mounting block is slidably connected to a sliding rod. A screening plate is provided at the upper end between the four sliding rods. A spring is provided between the upper surface of the mounting block and the lower surface of the screening plate. The spring is movably sleeved with the adjacent sliding rod on the same side. A vibration motor is provided at the lower center of the screening plate, thus realizing the rapid screening of bean products.

[0010] The upper end of the screening box is equipped with a protective cover. The transmission belt, pulley, worm gear, worm and fixed block are all located inside the protective cover, which prevents foreign objects from entering and ensures operational safety.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. After the bean products enter the feed end of the inverted cone-shaped screening box, the motor-driven spiral conveyor rod 2 first disperses the bean products. Its spiral blades push the bean products to both ends by rotating in opposite directions, so that the bean products enter multiple diversion hoppers evenly. At the same time, the transmission component synchronously drives the spiral conveyor rod 1 in all diversion hoppers to rotate, so that the bean products are further pushed to both ends in multiple diversion hoppers and finally evenly spread on the surface of the screening plate. This ensures that the bean products can be evenly spread on the screening plate, ensuring the uniformity of the feed and the uniformity of the distribution on the screening plate, thereby improving the screening effect of bean product particles and avoiding the problem of uneven screening caused by the accumulation of bean product particles on the screening plate. Finally, the screening mechanism realizes the screening of bean products.

[0012] 2. When the second screw conveyor rotates, it drives the worm gear through the linkage of the pulley and the transmission belt. When the worm gear rotates, it drives the first screw conveyor in all the diversion buckets to rotate synchronously through the worm wheel that meshes with it, thus achieving the effect of rapid synchronous drive.

[0013] 3. The screening plate is driven by a vibrating motor to make the sliding rod vibrate up and down, and the elastic buffer of the spring is used to achieve high-frequency screening, thereby realizing the rapid screening of bean products. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides a sieving structure for soybean products, such as... Figure 1-7As shown: A screening box 100 is included for mounting a screening mechanism. The inlet end of the screening box 100 is equipped with a dispersing component for dispersing bean products. The dispersing component includes multiple diversion hoppers 200 evenly arranged at the upper end of the inner cavity of the screening box 100. Each of the multiple diversion hoppers 200 is rotatably connected to a first spiral conveyor rod 201. A second spiral conveyor rod 202 is rotatably connected to the inlet end of the screening box 100. The inlet end of the screening box 100 is inverted conical in shape. The end of the second spiral conveyor rod 202 is equipped with a transmission mechanism for driving all the first spiral conveyor rods 201. The rotating transmission components and the diversion hoppers 200 are all V-shaped. The whole composed of multiple diversion hoppers 200 is distributed at a 90-degree offset from the feed end of the screening box 100. The first spiral conveyor rod 201 and the second spiral conveyor rod 202 are both composed of a rod body and spiral blades at both ends of the rod body. The spiral directions of the spiral blades at both ends of the first spiral conveyor rod 201 and the second spiral conveyor rod 202 are opposite. The dispersing component also includes a motor 203 located at one end of the upper part of the screening box 100. The output shaft of the motor 203 is fixedly connected to one end of the second spiral conveyor rod 202.

[0018] After the bean products enter the feed end of the inverted cone-shaped screening box 100, the spiral conveyor rod 202 driven by the motor 203 first disperses the bean products. Its spiral blades push the bean products to both ends by rotating in opposite directions, so that the bean products enter the multiple diversion hoppers 200 evenly. At the same time, the spiral conveyor rod 201 in all the diversion hoppers 200 is driven to rotate synchronously by the transmission component, so that the bean products are further pushed to both ends in the multiple diversion hoppers 200 and finally evenly spread on the surface of the screening plate 402. This ensures that the bean products can be evenly spread on the screening plate 402, ensuring the uniformity of the feed and the uniformity of the distribution on the screening plate 402, thereby improving the screening effect of bean product particles and avoiding the problem of uneven screening caused by the accumulation of bean product particles on the screening plate 402. Finally, the screening mechanism realizes the screening of bean products.

[0019] like Figure 2-5 As shown, the transmission component includes fixed blocks 300 symmetrically arranged on one side of the upper end of the screening box 100. A worm gear 301 is rotatably connected between the two fixed blocks 300. A worm wheel 302 is provided at one end of the spiral conveying rod 201 near the worm gear 301. All worm wheels 302 are meshed with the worm gear 301. The transmission component also includes pulleys 303 respectively arranged at one end of the spiral conveying rod 202 and the worm gear 301. The two pulleys 303 are connected by a transmission belt 304.

[0020] When the second spiral conveyor rod 202 rotates, it drives the worm gear 301 through the linkage of the pulley 303 and the transmission belt 304. When the worm gear 301 rotates, it drives the first spiral conveyor rod 201 in all the diversion buckets 200 to rotate synchronously through the worm wheel 302 that meshes with it, thus achieving the function of rapid synchronous driving.

[0021] like Figure 4-7 As shown, the screening mechanism includes mounting blocks 400 symmetrically arranged at the four corners of the inner cavity of the screening box 100. Each mounting block 400 is slidably connected to a sliding rod 401. A screening plate 402 is provided at the upper end between the four sliding rods 401. A spring 403 is provided between the upper surface of the mounting block 400 and the lower surface of the screening plate 402. The springs 403 are movably sleeved with the adjacent sliding rods 401 on the same side. A vibration motor 404 is provided at the lower center of the screening plate 402.

[0022] The screening plate 402 drives the sliding rod 401 to vibrate up and down through the vibration motor 404, and achieves high-frequency screening with the help of the elastic buffer of the spring 403, thereby realizing the rapid screening of bean products.

[0023] like Figure 1-2 As shown, the upper end of the screening box 100 is provided with a protective cover 500, and the transmission belt 304, pulley 303, worm gear 302, worm 301 and fixing block 300 are all located inside the protective cover 500.

[0024] The protective cover 500 seals the transmission components, preventing foreign objects from entering and ensuring operational safety.

[0025] The working principle of the bean product screening structure provided by this utility model is as follows: After the bean products enter the inverted conical screening box 100 through the feeding end, the spiral conveyor rod 202 driven by the motor 203 first disperses the bean products. Its spiral blades push the bean products to both ends through opposite rotation, so that the bean products enter the multiple diversion hoppers 200 evenly. At the same time, the spiral conveyor rod 202, through the meshing of the end worm wheel 302 and the worm 301, and the linkage of the pulley 303 and the transmission belt 304, synchronously drives the spiral conveyor rod 201 in all the diversion hoppers 200 to rotate, so that the bean products are further dispersed. Multiple V-shaped diversion hoppers 200 push the material to both ends and finally evenly spread it onto the surface of the screening plate 402, ensuring that the bean products can be evenly spread on the screening plate 402. This ensures the uniformity of the feeding and distribution of the bean products on the screening plate 402, thereby improving the screening effect of bean product particles and avoiding the problem of uneven screening caused by the accumulation of bean product particles on the screening plate 402. The screening plate 402 is driven by the vibration motor 404 to drive the sliding rod 401 to vibrate up and down, and the elastic buffer of the spring 403 is used to achieve high-frequency screening. The protective cover 500 seals the transmission components, preventing foreign objects from entering and ensuring operational safety.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
