Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material screening, in particular to a soybean screening device. Background Art
[0002] Soybean is an important legume plant, widely used in food, oil, feed and other purposes. However, soybeans need to be screened before use to screen out impurities or soybeans of unqualified quality. The screening is achieved through a screening machine. When screening, the soybeans are poured onto the sieve plate of the screening machine, and the sieve plate is vibrated by a vibrator. Unqualified soybeans and impurities will fall from the sieve plate, and the qualified soybeans can be collected.
[0003] When screening soybeans, they are poured directly onto the sieve plate of the screening machine. Since soybeans are oval in shape, they are very easy to roll on the sieve plate. During screening, soybeans of unqualified quality fall out together with soybeans of qualified quality before they fall from the sieve. Soybeans of unqualified quality will still exist among the screened soybeans. Therefore, this application provides a soybean screening device to meet the needs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a soybean screening device to solve the problem that soybeans of unqualified quality may still exist among the screened soybeans.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] A soybean screening device includes a housing and an elastic support installed at the bottom of the housing, a discharge port is provided at the bottom of the housing, a vibrator is fixed to the bottom of the housing, a sieve plate inclined toward the discharge port is fixed inside the housing, and further includes:
[0007] There are two groups of auxiliary screening components, each of which includes two square shells. The adjacent square shells are inclined in opposite directions, and the facing surfaces are fixedly connected to the inner wall of the outer shell. A blanking port is formed between the bottom of the square shell and the outer shell. A through groove connected to the square shell is provided on the surface of the screen plate. A through hole is provided on the upper surface of the square shell facing the screen plate. A screen is fixed on the inner wall of the through hole, and the cross-section of the screen is wavy.
[0008] Preferably, the depth of the grooves of the screen is smaller than the diameter of the soybeans.
[0009] Preferably, a fixed plate is fixed on the side of the square shell away from the screen, a guide rod is fixed on the surface of the fixed plate, the guide rod is parallel to the square shell and faces the blanking port, an adjustment plate is movably sleeved on the surface of the guide rod, the adjustment plate fits on the side of the square shell, a threaded hole is opened on the side of the adjustment plate, and a screw is threadedly connected to the inner wall of the threaded hole. When in use, the screw is against the side of the square shell.
[0010] Preferably, a triangular plate is fixed to a side of the fixing plate away from the guide rod, and the triangular plate is fixed to the side surface of the square shell.
[0011] Preferably, a sphere is fixed to the end of the screw.
[0012] Preferably, the surface of the sphere is provided with anti-slip stripes.
[0013] Preferably, the guide rod is vertically arranged to the fixing plate.
[0014] Preferably, the adjustment plate is an iron plate.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] In the above scheme, by setting up an auxiliary screening component, after pouring the soybeans onto the sieve plate, the soybeans will roll down along the sieve plate and come into contact with the screen. The screen prevents the soybeans from rolling down quickly, forcing the time the soybeans are on the sieve plate to increase, making the soybean screening more thorough. When the sieve holes on the sieve plate are blocked, the soybeans can still be screened through the screen. The screen and the sieve plate cooperate in screening at the same time, and the soybean screening is more thorough without affecting the screening efficiency.
[0017] By setting up an adjustment plate, when the soybeans are of low quality or contain more impurities, the adjustment plate is moved to make the drop opening smaller, reduce the flow rate of the soybeans, continue to increase the time the soybeans stay on the screen, and further screen out impurities or unqualified soybeans.

[0033] like Figures 1-8 As shown, an embodiment of the present invention provides a soybean screening device, comprising a housing 2 and an elastic support 1 installed at the bottom of the housing 2, a discharge port being provided at the bottom of the housing 2, a vibrator being fixed to the bottom of the housing 2, a screen plate 3 being fixed inside the housing 2 and tilted toward the discharge port, and further comprising:
[0034] There are two groups of auxiliary screening components 4, and each group of auxiliary screening components 4 includes two square shells 42. The adjacent square shells 42 are inclined in opposite directions, and the facing surfaces are fixedly connected to the inner wall of the outer shell 2. A drop port 9 is formed between the bottom of the square shell 42 and the outer shell 2. A through groove 41 connected to the square shell 42 is provided on the surface of the screen plate 3. A through hole is provided on the upper surface of the square shell 42 facing the screen plate 3. A screen 43 is fixed on the inner wall of the through hole. The cross-section of the screen 43 is wavy. The wavy shape increases the contact area with the soybeans, making screening more convenient and easier to screen out impurities or unqualified soybeans.
[0035] like Figure 7 As shown, in this embodiment, the depth of the groove of the screen 43 is smaller than the diameter of the soybeans to prevent the soybeans from staying in the groove.
[0036] like Figure 5 and Figure 6 As shown, in this embodiment, a fixing plate 5 is fixed to the side of the square shell 42 away from the screen 43, and a guide rod 6 is fixed on the surface of the fixing plate 5. The guide rod 6 is parallel to the square shell 42 and faces the direction of the blanking port 9. An adjusting plate 7 is movably sleeved on the surface of the guide rod 6. The adjusting plate 7 is attached to the side of the square shell 42. A threaded hole is provided on the side of the adjusting plate 7. The inner wall of the threaded hole is threadedly connected with a screw 8. When in use, the screw 8 is against the side of the square shell 42. The adjusting plate 7 can adjust the size of the blanking port 9, which can be adjusted according to the quality of the soybeans to ensure the thoroughness of the screening.
[0037] like Figure 4 and Figure 5 As shown, in this embodiment, a triangular plate is fixed on the side of the fixing plate 5 away from the guide rod 6. The triangular plate is fixed to the side of the square shell 42. The triangular plate shares part of the force on the fixing plate 5, thereby increasing the stability of the fixing plate 5 during use.
[0038] like Figure 6 As shown, in this embodiment, a sphere is fixed to the end of the screw 8 to increase the contact area with the hand, making it more convenient to rotate the screw 8 with the fingers.
[0039] like Figure 6 As shown, in this embodiment, the surface of the sphere is provided with anti-slip stripes to increase the friction between the hand and the sphere to prevent the fingers from sliding against the sphere.
[0040] like Figure 5As shown, in this embodiment, the guide rod 6 is vertically arranged between the fixing plate 5, so that the adjustment plate 7 can move along the direction of the square shell 42, avoiding the adjustment plate 7 from tilting upward or downward.
[0041] like Figure 1-Figure 7 As shown, in this embodiment, the adjustment plate 7 is an iron plate. Metal iron is cheap and wear-resistant, and has a long service life.
[0042] Working principle: when in use, pour soybeans on the high place of the screen plate 3, and the soybeans will move downward along the screen plate 3. The vibrator at the bottom of the shell 2 will vibrate to screen all the soybeans on the screen plate 3, and the shell 2 will vibrate on the elastic support 1. Secondly, the soybeans will come into contact with the screen 43 when rolling downward, and the screen 43 will prevent the soybeans from rolling downward quickly, so that the soybean screening will be more thorough. Secondly, part of the soybeans will be screened from the screen 43, and unqualified soybeans or impurities will fall from the through slot 41. The screened soybeans will fall out from the discharge port of the shell 2;
[0043] When the soybean quality is low or there are more impurities, the screw 8 is rotated by the ball to move the adjustment plate 7, and the adjustment plate 7 will slide on the guide rod 6 of the fixed plate 5. After the adjustment is completed, the screw 8 is tightened again to reduce the drop port 9, reduce the speed at which the soybeans pass, increase the time the soybeans stay on the screen plate 3, and screen the soybeans more thoroughly.
[0044] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.
[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
