Description

Technical Field

[0001] This utility model belongs to the field of soybean screening technology, and in particular relates to a portable soybean screening device. Background Technology

[0002] In a research experiment on intercropping soybeans with tobacco, some harvested soybeans were found to be empty, shriveled, or incomplete. Due to the small quantity, machine screening was inconvenient, while manual screening was time-consuming and labor-intensive. Therefore, a soybean screening device is needed to save labor and quickly and efficiently screen out plump soybeans.

[0003] Existing patent CN115957967A provides a soybean seed screening device, including a feeding platform with a storage hopper at the top and a discharge chute connected to the storage hopper on the side wall of the feeding platform. A pouring platform that cooperates with the discharge chute is also fixedly installed on the side wall of the feeding platform. A support platform is also provided on one side of the feeding platform. This device can screen high-quality soybean seeds through the synergistic effect of various structures. However, the structure of this device is relatively complex and it is not suitable for soybean screening in scientific research experiments involving tobacco and soybean intercropping. Utility Model Content

[0004] The purpose of this invention is to solve the problem of complex structure in existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable soybean screening device includes a screening device, an adjustment device, and a collection device. The adjustment device is installed at the bottom of the screening device, and the collection device is installed at the right end of the screening device.

[0007] The bottom of the screening device has a groove in the middle for connecting the screening plate. Slide rails are provided at both ends of the groove, and protrusions are provided at both ends of the screening plate. The cooperation between the slide rails and the protrusions enables the screening device and the screening plate to slide together. The screening plate has blades that are evenly spaced.

[0008] Furthermore, the rear sidewall of the screening plate is higher than the blade.

[0009] Furthermore, a baffle is snapped onto the right side wall of the screening device, and a handle is provided on the baffle.

[0010] Furthermore, the adjustment device includes a support rod, an adjustment frame, and an adjustment groove; one end of the support rod is fixedly installed on the screening device, and the other end of the support rod is inserted into the adjustment groove on the adjustment frame, which is installed at the bottom right side of the screening device.

[0011] Furthermore, the collection device is a detachable box with a movable baffle at the bottom.

[0012] Beneficial effects:

[0013] This invention effectively screens soybeans using a screening plate located in the middle of the bottom of the screening device. The spaced blades on the screening plate improve screening accuracy and efficiency, allowing for the differentiation of soybeans of different sizes or qualities. Furthermore, adjusting the support rod changes the tilt angle of the screening device to achieve the desired soybean screening effect. This device is adjustable in tilt angle, compact, easy to move, and convenient to store, saving time and effort. Attached Figure Description

[0018] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Please see Figure 1 and Figure 2 A portable soybean screening device includes a screening device 1, a collection device 2, and an adjustment device 3; the bottom of the screening device 1 is equipped with an adjustment device 3 for adjusting the tilt of the screening device 1, and the right side of the screening device 1 is equipped with a collection device 2 for collecting soybeans, wherein the collection device 2 is a detachable box with a movable baffle at the bottom.

[0021] The bottom of the screening device 1 has a groove 6 at the center for connecting the screening plate 4. Slide rails 12 are provided at both ends of the groove 6, and protrusions (not shown in the figure) are provided at both ends of the screening plate 4. The screening device 1 and the screening plate 4 are slidably connected through the cooperation of the slide rails and protrusions. The screening plate 4 has multiple blades 5, which are evenly spaced and used for screening soybeans. When the device is not in use, the rear wall of the screening plate 4 abuts against the rear wall of the screening device 1, and the front end of the screening plate 4 is inserted into the groove on the front wall of the screening device 1. The rear wall of the screening plate 4 is higher than the blades 5. By pulling the rear wall of the screening plate 4, the screening plate 4 slides back and forth, thus screening soybeans. During soybean screening, the speed of the screening plate 4 is not too fast, and the distance between the front end of the screening plate 4 and the front wall of the screening device 1 is within a certain range. A baffle is engaged on the right side wall of the screening device 1, and a handle 8 is provided on the baffle. By pulling the handle 8 upwards, soybeans can fall into the collection device 2.

[0022] The adjustment device 3 includes a support rod 9, an adjustment frame 10, and an adjustment groove 11. One end of the support rod 9 is fixedly installed on the screening device 1, and the other end of the support rod 9 is inserted into the adjustment groove 11 on the adjustment frame 10. The adjustment frame 10 is installed at the bottom right side of the screening device 1. Several adjustment grooves 11 are evenly distributed on the adjustment frame 10. By inserting the support rod 9 into different adjustment grooves 11, the inclination of the screening device 1 can be changed.

[0023] The working principle of this utility model:

[0024] Soybeans are mainly categorized as plump and unplump, and whole and unwhole. Plump and whole soybeans are usually the preferred type, as they have strong abrasion resistance and high sliding speed. Therefore, this device utilizes the different frictional forces of different types of soybeans to quickly and conveniently select the desired soybeans.

[0025] First, pour the soybeans into the screening device 1. Pull the rear wall of the screening plate 4 by hand to make the device shake back and forth, so that the unripe and incomplete soybeans fall from the leaf 5, and the plump and complete soybeans pile up at the bottom of the screening device 1. Pull the handle 8 upward by hand to move the right side wall of the screening device 1 upward, so that the soybeans fall from the bottom of the screening device 1 into the collection device 5.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
