DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0030] For examples, see Figure 1-Figure 8 , a soybean soaking and screening device for soybean product production shown in the figure includes a screening box 101 and a feed pipe 102 installed on the screening box 101, a feed control valve 103 is installed on the feed pipe 102, and also includes a bottom plate 2 slidably connected to the inside of the screening box 101, a lifting component for lifting the bottom plate 2 and a guide component for guiding during the lifting process are provided on the screening box 101, and the lifting component and the guide component are respectively located on both sides of the screening box 101, and a circulating flow component for circulating the soaking liquid inside the screening box 101 is provided on the screening box 101, and a separation component for separating soybeans from stones during the soaking liquid circulation process is provided on the bottom plate 2;

[0031] The circulation flow component includes a water pump 501 installed on one side of the screening box 101, the water outlet of the water pump 501 is communicated with the inside of the screening box 101, and a U-shaped tube 502 is arranged on the outside of the screening box 101, one end of the U-shaped tube 502 is communicated with the screening box 101, and the other end of the U-shaped tube 502 is connected to the water inlet of the water pump 501;

[0032] The separation component includes a baffle 601 fixed to the upper end of the bottom plate 2, and the interior of the screening box 101 forms a first collection chamber 1011 and a second collection chamber 1012 under the dividing action of the baffle 601, the feed pipe 102 is connected to the first collection chamber 1011, and a through slot 602 is provided on the baffle 601, and the through slot 602 is located between the water outlet end of the water pump 501 and the water inlet end of the U-shaped tube 502. A pressing component for pressing the floating soybeans after soaking is provided at the upper end of the baffle 601, and a control component for controlling the blocking and opening of the through slot 602 is provided on one side of the baffle 601;

[0033] It should be noted here that: during the soaking, descaling and screening operations of soybeans by the screening box 101, the separation component, the circulating flow component, the pressing component and the control component cooperate with each other to achieve automatic separation of bad beans, stones and soybean skins during the soaking and descaling of soybeans, which is convenient for subsequent processing operations of soybeans. In the separation process, the soybeans suspended after soaking are further screened and determined, which reduces the probability of some normal soybeans being misscreened and improves the accuracy of soaking and screening of soybeans.

[0034] Preferably, the control assembly includes a first mounting frame 701 fixed to one side of the baffle 601, a blocking plate 702 for blocking the through slot 602 is rotatably connected to the first mounting frame 701, and a first motor 703 for driving the blocking plate 702 is installed on the first mounting frame 701;

[0035] It should be noted that: the blocking plate 702 is driven to rotate by the first motor 703, and the blocking plate 702 is controlled to block or open the through slot 602 by the rotation of the blocking plate 702;

[0036] It is worth noting here that: during the process of putting the soybeans in, the blocking plate 702 does not block the through groove 602 to avoid causing obstruction in the separation of the soybeans and stones. After the separation and in the process of driving the bottom plate 2 to move upward, the blocking plate 702 is driven to block the through groove 602. By blocking the through groove 602, the sieved stones and soybeans are prevented from mixing again through the through groove 602.

[0037] Preferably, the pressing assembly includes a second mounting frame 801 fixed to the upper end of the baffle 601, a pressing plate 802 is rotatably connected to the second mounting frame 801 via a torque shaft, a plurality of flow slots 803 are provided on the pressing plate 802, and a driving assembly for driving the pressing plate 802 is provided on the baffle 601;

[0038] It should be noted here that: through the reset effect of the driving component and the torque shaft on the pressure plate 802 after the force is applied, the pressure plate 802 is caused to reciprocate on the second mounting frame 801 as the mounting shaft 902 rotates. During the reciprocating rotation of the pressure plate 802, the cleaning liquid flows through the flow groove 803 on the pressure plate 802 and presses the soybeans suspended in the cleaning liquid through the pressure plate 802. During the pressing process, the suspended soybeans will sink under the action of the pressing force due to the effects of static electricity and water tension.

[0039] Preferably, the driving assembly includes a third mounting frame 901 fixed on the baffle 601, a mounting shaft 902 is rotatably connected to the third mounting frame 901, a first L-shaped transmission plate 903 is fixed to the lower end of the pressure plate 802, a plurality of protrusions 904 for pushing against one end of the first L-shaped transmission plate 903 are fixed in an annular array on the mounting shaft 902, and a fan blade 905 is fixed on the mounting shaft 902;

[0040] It should be noted here that the circulating cleaning liquid flows through the through groove 602 of the baffle 601. During the circulation process, the pressure of the circulating cleaning liquid on the fan blade 905 pushes the installation shaft 902 to rotate between the third installation frame 901.

[0041] Preferably, a peeling assembly for peeling soybeans is provided above the bottom plate 2, and the peeling assembly includes a shaking plate 1001 arranged on the second collecting chamber 1012, the shaking plate 1001 is located above the bottom plate 2 and is connected through a plurality of connecting assemblies, and a plurality of filtering holes 1002 for peeling and filtering are provided on the shaking plate 1001; the connecting assembly includes a strip plate 1101 fixed on the bottom plate 2, a plurality of sleeves 1102 are fixed on the strip plate 1101, and a slide bar 1103 is slidably connected to each sleeve 1102, and one end of each slide bar 1103 is fixed to one side of the shaking plate 1001, and the other end of the slide bar 1103 is located inside the sleeve 1102 and fixed with a slide plate 1104, and a spring 1105 for connecting the slide plate 1104 is installed inside the sleeve 1102; a second L-shaped transmission plate 12 for pushing against the protrusion 904 is fixed to the upper end of the shaking plate 1001;

[0042] It should be noted that: during the rotation of the mounting shaft 902, the protrusions 904 push against the second L-shaped transmission plate 12 in turn, and the springs 1105 on the connecting assembly guide the reset of the shaking plate 1001 after the force is applied, so that the shaking plate 1001 shakes inside the second collecting chamber 1012 as the mounting shaft 902 rotates. During the shaking of the shaking plate 1001, the soybeans falling onto the shaking plate 1001 are separated from the soybean skins produced by the shaking plate 1001.

[0043] It is worth noting here that the movement of the rocking plate 1001 after being subjected to force is guided by the action of the sleeve 1102, the slide rod 1103 and the slide plate 1104 on the connecting assembly.

[0044] Preferably, the screening box 101 is provided with a collecting assembly for collecting the separated stones, soybeans and soybean hulls respectively, the collecting assembly comprising a U-shaped discharge hopper 1301 and an L-shaped discharge hopper 1302 installed on the outside of the screening box 101, the U-shaped discharge hopper 1301 and the L-shaped discharge hopper 1302 are connected to the interior of the screening box 101, a guide plate 1303 is fixed on the L-shaped discharge hopper 1302 and is inclined, and there is a gap between the guide plate 1303 and the bottom of the L-shaped discharge hopper 1302, and the bottom plate 2 is inclined toward the U-shaped discharge hopper 1301 and the L-shaped discharge hopper 1302 inside the screening box 101.

[0045] Preferably, the lifting assembly includes a first L-shaped frame 301 fixed on the bottom plate 2, a threaded rod 302 is rotatably connected to the first L-shaped frame 301, a threaded tube 303 is threadedly engaged with the threaded rod 302, a first connecting plate 304 is fixed to one end of the threaded tube 303, the first connecting plate 304 is fixed to the outer side of the screening box 101, and a second motor 305 for driving the threaded rod 302 is installed on the first L-shaped frame 301; the guide assembly includes a second connecting plate 401 fixed to the outer side of the screening box 101, a cylinder 402 is fixed to the upper end of the second connecting plate 401, a round rod 403 is slidably connected to the cylinder 402, a second L-shaped frame 404 is fixed to one end of the round rod 403, and one end of the second L-shaped frame 404 is fixed to the bottom plate 2;

[0046] It should be noted here that: the threaded rod 302 is driven to rotate by the second motor 305. During the rotation of the threaded rod 302, the base plate 2 is driven to move through the mutual engagement transmission between the threaded rod 302 and the threaded tube 303. During the movement of the base plate 2, the guiding effect of the round rod 403 and the cylinder 402 causes the base plate 2 to move up and down after being subjected to force.

[0047] Working principle: during the soaking, descaling and screening operation of soybeans through the screening box 101, the soybeans to be soaked, descaled and screened are transported to the screening box 101 through the feeding pipe 102 and fall into the first collecting chamber 1011. During the falling process, the falling soybeans are soaked, descaled and screened by the cleaning liquid inside the screening box 101. Due to the hollowness of the soybeans and the tension of static electricity and water, part of the soybeans are suspended on the surface of the cleaning liquid. During the process of putting the soybeans to be soaked, descaled and screened, the water pump 501 is started. Through the driving action of the water pump 501 and the connecting and conveying action of the U-shaped tube 502, the cleaning liquid inside the screening box 101 circulates between the screening box 101 and the U-shaped tube 502.

[0048] During the circulation process, the circulating cleaning liquid flows through the through groove 602 of the baffle 601. During the circulation process, the pressure of the circulating cleaning liquid on the fan blade 905 pushes the installation shaft 902 to rotate between the third installation frame 901. During the rotation of the installation shaft 902, the protrusions 904 successively push against one end of the first L-shaped transmission plate 903 and the torsion shaft resets the pressure plate 802 after the force is applied, so that the pressure plate 802 is moved on the second installation frame 801 as the installation shaft 902 rotates. The pressing plate 802 reciprocates and rotates back and forth. During the reciprocating rotation of the pressing plate 802, the cleaning liquid flows through the flow slot 803 on the pressing plate 802 and presses the soybeans suspended on the cleaning liquid through the pressing plate 802. During the pressing process, the suspended soybeans will sink under the action of the pressing force due to the effects of static electricity and water tension, while the soybeans with hollow interiors due to damage remain suspended. The soybeans suspended after soaking are further screened and determined, thereby reducing the probability of some normal soybeans being misscreened and improving the accuracy of soybean soaking and screening.

[0049] In the process of circulating the cleaning liquid inside the screening box 101 through the circulating flow component, the circulating cleaning liquid generates a lateral thrust on the falling soybeans, and under the action of the soybeans' own gravity and thrust, the soybeans fall parabolically inside the screening box 101. Since the soybeans themselves are relatively light, they are thrown out a greater distance after falling, so that the soybeans are forced to pass through the through slots 602 on the baffle 601 during the falling process and fall onto the shaking plate 1001 of the second collecting chamber 1012 for collection. However, the stones mixed in the soybeans are heavy, so they are thrown out a shorter distance after falling, so that the stones mixed in the soybeans cannot pass through the through slots 602 and fall into the first collecting chamber 1011 for collection, thereby achieving soybean soaking. During the soaking and descaling process, the stones mixed with the soybeans are automatically separated and screened. During the rotation of the installation shaft 902, the protrusions 904 are pushed against the second L-shaped transmission plate 12 in turn, and the springs 1105 on the connecting assembly reset the guide assembly of the shaking plate 1001 after the force is applied, so that the shaking plate 1001 shakes inside the second collecting chamber 1012 as the installation shaft 902 rotates. During the shaking of the shaking plate 1001, the soybeans falling on the shaking plate 1001 are separated from the soybean skins produced by the soybeans themselves. The separated soybean skins pass through the filtering holes 1002 and fall onto the bottom plate 2 for collection, thereby realizing the automatic separation of bad beans, stones and soybean skins during the soaking and descaling process of the soybeans, which is convenient for the subsequent processing of the soybeans.

[0050] After the bad beans, stones and soybean hulls are separated, the bottom plate 2 is driven to move upward through the lifting assembly and the guide assembly, so that the bottom plate 2 moves to one side of the U-shaped discharge hopper 1301 and the L-shaped discharge hopper 1302. During the upward movement, the suspended bad beans fall onto the bottom plate 2 of the first collecting chamber 1011. After the lifting movement is completed, the stones and bad beans separated and collected inside the first collecting chamber 1011 are transported outward through the U-shaped discharge hopper 1301 and collected through the guiding effect of the inclined bottom plate 2. The second collecting chamber 1012 The soybeans and soybean hulls separated and collected internally are transported outward and collected through the L-shaped discharge hopper 1302. During the transportation process, the soybean hulls are transported to the front side of the L-shaped discharge hopper 1302 through the guiding and diverting effect of the inclined guide plate 1303 with a gap at the bottom of the L-shaped discharge hopper 1302, while the soybeans are transported to one side of the L-shaped discharge hopper 1302 under the blocking and diversion effect of the guide plate 1303, thereby realizing the separate collection of the soybeans and soybean hulls.

[0051] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
