Description

Technical Field

[0001] The utility model relates to the technical field of grain detection, in particular to a portable whole soybean grain rapid separation screen. Background Art

[0002] Currently, soybean quality testing is primarily based on GB1352-2009, which primarily assesses soybean quality based on the following criteria: intact kernels, damaged kernels, heat-damaged kernels, and impurities. Due to their unique characteristics, most soybean products are prone to breaking into two or more pieces during procurement, warehousing, and storage, resulting in a significant number of broken kernels. This breakage is counted separately from damage caused by soybean shriveling, insect infestation, and other factors.

[0003] The current existing soybean screening device is to place soybeans into multiple mutually nested filter cylinders, and then rotate the filter cylinders to screen and filter the soybeans. However, the screening diameter of the screen in the existing device is fixed during screening, and different soybean varieties usually have different diameters. Even soybeans of the same variety may have different diameters due to the influence of the natural environment and geographical location. When screening soybeans, it is usually necessary to replace the corresponding screen according to the diameter of the soybeans to avoid invalid screening due to mismatch of the screen screening diameters. Utility Model Content

[0026] By screwing in or out the adjusting nut 3221, the guide rod 3222 is driven to slide inside the mounting frame 31, so that the guide rod 3222 and the slide rail 3223 are moved closer or farther away, thereby adjusting the inclination angle of the connecting rod 3225 that slides with the guide rod 3222 and the slide rail 3223 at both ends, so as to adjust the maximum distance between the two adjacent connecting rods 322, and thus adjust the distance between the screening wires 321. The two screening assemblies 32 are vertically and closely arranged so that the two groups of screening wires 321 form a screen. By changing the distance between the screening wires 321 in the two groups of screening assemblies 32, the screening diameter of the screen is adjusted to adapt to the screening of soybeans of different diameters. At the same time, when the shape of the soybeans is different from that of ordinary soybeans (such as being smaller than ordinary soybeans, more severely broken, etc.), they will also be eliminated through the screening of the screen.

[0027] As a possible implementation of this scheme, preferably, the cleaning assembly 35 includes mounting plates 355 symmetrically arranged at the left and right ends of the outer wall of the mounting frame 31, a screw rod 352 circumferentially rotatable between the two mounting plates 355, a connector 353 threadedly connected to the screw rod 352 and movably inserted into the mounting frame 31 along the width direction of the whole grain collection box 34, a pair of cleaning brushes 354 symmetrically fixed at the top and bottom of the connector 353 and with opposite sides respectively abutting against the screening wires 321 in the two screening assemblies 32, and a cleaning brush 354 fixed on the outer wall of any one of the mounting plates 355 and with the driving end passing through The mounting plate 355 is fixedly connected to the rotating motor 351 with the screw rod 352; the side walls of the mounting frame 31 are respectively provided with a first slide groove 311 and a second slide groove 312 adapted to the top and bottom of the connecting piece 353; the rotating motor 351 drives the screw rod 352 to rotate, so that the connecting piece 353 drives the two cleaning brushes 354 to move, which can, on the one hand, push the whole soybeans sieved out of the screen into the whole soybean collection box 34 for collection, and on the other hand, clean the screening wire 321 of the screen to avoid some soybeans from remaining on the screen as much as possible, so as to reduce the impact on the subsequent screening of soybeans.

[0028] As a possible implementation scheme of this solution, preferably, the rotating mechanism 2 includes a driving motor 21 fixed to the bottom of the mounting bracket 1, and a rotating disk 22 rotatably arranged on the top of the mounting bracket 1 and fixedly connected to the driving end of the driving motor 21; the mounting frame is fixed around the upper surface of the rotating disk 22; the rotating disk 22 is driven to rotate by the driving motor 21, thereby driving the screening mechanism 3 to rotate, thereby improving the screening efficiency of the screening mechanism 3.

[0030] As a possible implementation of the present scheme, preferably, a guide ring 36 is fixed around the upper inner surface of the mounting frame 31, the lower surface of which abuts against the upper surface of the cleaning brush 354 located above, and the upper surface of the guide ring 36 gradually tilts downward from the outside to the inside; through the setting of the guide ring 36, the soybeans can be guided to the middle position of the screen.

[0031] As a possible implementation of this solution, preferably, a screen cover 37 is provided on the top of the mounting frame 31 ; the provision of the screen cover 37 can prevent soybeans from rotating out from the top when the screening mechanism 3 is subjected to rotary screening.

[0032] The working principle of this device is:

[0033] The device is clamped near the soybeans by two clamping assemblies 12, and then the adjusting nut 3221 is screwed in or out according to the diameter of the soybeans to adjust the screening spacing of the screen. Then, the soybeans are poured onto the screen from above the guide ring 36, and the screen cover 37 is covered on the top of the mounting frame 31. Then, the driving mechanism 21 drives the rotating disk 22 to drive the screening mechanism 3 to rotate to achieve accelerated screening of the soybeans. When passing through the screening, the whole soybeans and the soybeans with a crushed volume of less than 1 / 4 will be blocked by the screen and retained on the screen, while the soybeans with a crushed volume of more than 1 / 4 will pass through the screen and fall to the In the receiving tray 33, when the screening is completed, the screw rod 352 is driven to rotate by rotating the motor 351, so that the connecting piece 353 drives the cleaning brush 354 to move to the side of the whole grain collection box 34. On the one hand, the soybeans remaining on the screen can be pushed into the whole grain collection box 34 for collection. On the other hand, the screen can also be cleaned at the same time to avoid the influence of soybean residue on the screen on subsequent screening as much as possible; in this device, in order to make the screening wires 321 in the two groups of screening components 32 perpendicular to each other to form a screen, a scale line can be set on the outside of the adjusting nut 3221 (not shown in the figure).

[0034] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
