Description

Technical Field

[0001] The invention relates to the technical field of bean product processing equipment, and in particular to a soybean screening mechanism for bean product processing. Background Art

[0002] In the processing of soy products, soybean screening is a key step aimed at removing impurities, inferior and unqualified soybeans to ensure the quality of the final product.

[0003] During use of the soybean screening machine in the prior art, the soybeans mixed in the sacks are generally poured into the feeding hopper for discharge. Although the feeding hopper is provided with an adjusting component for adjusting the size of the discharge port, the size of the discharge port needs to be adjusted to the minimum because this will make the discharge speed of the soybeans controllable. If it is opened to the maximum, the discharge speed will be too high, causing the soybean material to accumulate on the surface of the screen and affect the efficiency of screening. For example, the soybeans mixed in the sacks are generally mixed with a large amount of impurities such as bean shells, bean stalks, and bean leaves. The soybeans will be easily stuck by impurities such as bean shells at the discharge port in the feeding hopper, affecting the discharge speed, and the discharge port will be easily blocked, thereby greatly reducing the screening efficiency. It is even necessary to manually assist in moving the impurities stuck at the discharge port, which is very inconvenient. Therefore, the present application provides a soybean screening mechanism for soy product processing to meet the needs. Summary of the invention

[0044] Among them, when it is necessary to disassemble the n-type support frame 3 from the feeding hopper 2, the two hand-screwed screws 32 can be loosened, and then the two second nuts 518 can be loosened, and the second ring 516 can be removed from the second stud 517 respectively, so as to realize the disassembly of the entire n-type support frame 3; the air suction port 24 is connected to the air inlet of the fan through a pipeline. This is the existing technology and is not described in detail; the setting of the guiding slope 25 prevents the soybeans from directly entering the air suction port 24 after falling. The air suction port 24 absorbs light impurities through the operation of the fan and discharges them to the outside, while heavy impurities and soybeans will fall on the screening machine body 1 for screening intermittently with the operation of the intermittent feeding member 5.

[0046] The avoidance slope 33 is provided so that the soybeans are not easily blocked by one end of the U-shaped support plate 31 and cannot fall through the guide slope 25 .

[0047] like Figures 2 to 14As shown, in order to enable the scraper 6 to perform a reciprocating and telescopic motion while performing a reciprocating scraping action, such a motion trajectory makes it more effective in scraping away impurities such as bean shells, so the transmission member 4 is provided to include a guide seat 41 slidably connected to the n-type support frame 3, a groove is provided in the middle of the top end of the guide seat 41, and a protrusion is integrally formed in the middle of the bottom end of the guide seat 41, and the guide seat 41 is slidably connected to an adaptive guide groove provided on the n-type support frame 3, and a reciprocating screw 42 is transmission-connected to the guide seat 41, and both ends of the reciprocating screw 42 are rotatably connected to the n-type support frame 3, and the right end of the reciprocating screw 42 extends to the outside of the n-type support frame 3. , and is connected to the output shaft of the motor 43.

The plurality of teeth 471 are distributed in an equidistant array and fixed to the inner top wall of the n-type support frame 3.

[0048] Among them, the shape design of the guide seat 41 makes it more stable and reliable during the reciprocating movement in the guide groove; in addition, since the guide seat 41 is driven by the reciprocating screw 42 to move back and forth, the guide seat 41 will drive the crown gear 47 to move back and forth, and the cooperation between the crown gear 47 and the multiple teeth 471 prompts the crown gear 47 to rotate during the reciprocating movement, and cooperates with the design of the push-pull rod 46, so that the telescopic rod 44 performs reciprocating telescopic movement during the reciprocating movement, prompting the scraper 6 to realize an irregular movement trajectory, so that the impurities at the discharge port 21 of the feeding hopper 2 can be scraped off more effectively.

[0049] like Figures 2 to 13As shown, in order to facilitate the intermittent discharge of the soybeans falling on the guiding slope 25 at the discharge port 21, the intermittent feeding member 5 is provided, including a first gear 53 fixedly connected to the outer side of the left end extension of the reciprocating screw 42, the first gear 53 is a fan-shaped gear, and a second gear 55 is arranged below the first gear 53, the first gear 53 rotates clockwise to mesh with the second gear 55, the second gear 55 is fixedly connected to the outer side of the left end extension of the transmission shaft 54, both ends of the transmission shaft 54 ​​are rotatably connected to the n-type support frame 3, a baffle plate 51 is fixedly connected to the outer side of the transmission shaft 54, and avoidance recesses 519 are provided on both side walls of the baffle plate 51 near its bottom end, and a plurality of first lightweight slots 52 arranged in an equidistant array are also provided on the baffle plate 51, and two symmetrically distributed first lightweight slots 52 are fixedly connected to the back of the baffle plate 51.

[0052] Among them, the scraper 6 can be made of ABS plastic material as a whole, with an integrated molding structure design, and combined with the design of the third lightweight groove 66 and the second lightweight groove 64, the overall weight can be reduced. In addition, through the design of the connecting rod 67 and multiple connecting sleeves 68, the cross position can be reinforced to avoid shaking and affecting the overall scraping effect, and the design of the arc-shaped avoidance portion 69 and the weakened groove 62 makes it more convenient and quick to clamp or disassemble the clamping plate 61 on the mounting column 45.
