Description

Technical Field

[0001] This utility model relates to the field of soybean seed testing technology, specifically a screening device for a soybean plot intelligent seed testing platform. Background Technology

[0002] Soybeans are an important component of my country's grain production. Soybean traits, such as growth status and yield potential, are not only key indicators for assessing soybean quality but also crucial for identifying new varieties. Traditional soybean testing methods rely entirely on manual labor, with testers meticulously examining and recording various trait data for each soybean. This process is not only inefficient but also susceptible to subjectivity. With technological advancements, this work has been largely replaced by intelligent soybean testing platforms in small plots. Before testing on these platforms, soybeans typically undergo screening to avoid interference from impurities.

[0003] According to the "Agricultural Soybean Particle Screening Device" published in Chinese Patent Publication No. CN209680541U, the device includes a fixed base, with several limiting seats fixedly connected to the top of the fixed base. The outer wall of each limiting seat at the end away from the fixed base is sleeved and connected to the inner wall of a limiting block. The end of each limiting block at the end away from the limiting seat is fixedly connected to the bottom of a spring. The end of each spring at the end away from the limiting block is fixedly connected to the bottom of a limiting plate. The inside of the limiting plate is fixedly connected to the bottom of a vibrator. The end of the vibrator at the end away from the limiting plate is fixedly connected to the bottom of a support plate. A screening frame is fixedly connected to the top of the support plate. Several grooves are carved inside the screening frame. Several screening plates are provided inside the screening frame. A slider is fixedly connected to the bottom of both sides of each screening plate. The beneficial effect achieved by this invention is that by providing a fixed base, springs, and limiting seats, the soybean particles have good stability during screening.

[0004] The device uses a sieve to sieve soybeans. However, the broken soybeans are nearly hemispherical in shape and their size is similar to that of whole soybeans. They are difficult to remove through the sieve, which can easily lead to the residue of broken soybeans and affect the accuracy of subsequent seed evaluation platforms. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a screening device for a smart soybean planting platform, which can screen out broken soybeans, avoid the residue of broken soybeans, and prevent them from affecting the accuracy of the subsequent planting platform.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A screening device for a soybean plot intelligent seed evaluation platform includes a base. Two parallel, spaced-apart rods are mounted on the base. A single roller frame is slidably mounted on each of the two rods. Two rollers are rotatably mounted on the roller frame, arranged parallel and spaced apart. A conveyor belt is fitted onto the two rollers. The axes of the two rollers are perpendicular to the axes of the rods, and one end of each roller is inclined downwards to tilt the conveyor belt. One roller is connected to a roller motor. A swaying rod is suspended at the bottom of the roller frame. A vertical groove is provided on the swaying rod, and one end of the groove is slidably connected to a sliding rod. The sliding rod is horizontal, and its axis is perpendicular to the axis of the rod. The other end of the sliding rod is eccentrically mounted on a turntable, which is connected to a swaying motor. The swaying motor is fixedly mounted on the base.

[0008] Preferably, a support is provided on the roller frame at the higher end of the conveyor belt, and a receiving tray is provided on the support, the receiving tray being arranged parallel to the surface of the conveyor belt.

[0009] Preferably, the lower end of the receiving tray is provided with an opening, which is located at the rear end of the conveyor belt in the conveying direction.

[0010] Preferably, the receiving tray is equipped with a screen.

[0011] Preferably, a first receiving box is provided below the screen.

[0012] Preferably, a baffle is provided on the roller frame at the rear end of the conveyor belt in the conveying direction and outside the opening, and a second receiving box is provided at the front end of the conveyor belt in the conveying direction.

[0013] Preferably, a third receiving box is provided at the lower end of the conveyor belt.

[0014] Preferably, the base is further provided with a feeding box, the bottom of the feeding box is provided with a discharge port, and the discharge port is located above the receiving tray.

[0015] Preferably, the bottom of the feeding box is provided with an auger, and the auger is connected to an auger motor.

[0016] Preferably, a support plate is provided at the bottom of the conveyor belt, and the support plate is fixedly connected to the roller frame.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] By feeding soybeans from the higher end of the conveyor belt, the conveyor belt oscillates back and forth along its inclined direction, evenly distributing the soybeans on its surface. As the surface of the conveyor belt moves along its inclined direction, whole soybeans, being nearly spherical, easily roll along the inclined direction of the conveyor belt, while broken soybeans, being nearly hemispherical, do not roll easily and move along the inclined side of the conveyor belt. This process effectively separates the broken soybeans, preventing them from remaining and affecting the accuracy of subsequent seed evaluation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides the following technical solution:

[0026] Combination Figures 1 to 4As shown in this embodiment, a screening device for a soybean plot intelligent seed evaluation platform includes a base 1. Two smooth rods 2 are arranged parallel to each other on the base 1. The same roller frame 3 is slidably mounted on each of the two smooth rods 2. Two rollers 4 are rotatably mounted on the roller frame 3. The two rollers 4 are arranged parallel to each other and spaced apart. A conveyor belt 5 is sleeved on the two rollers 4. The axes of the two rollers 4 are perpendicular to the axes of the smooth rods 2, and one end of each roller 4 is inclined downwards to tilt the conveyor belt 5. One of the rollers 4 is connected to a roller motor 6. A swaying rod 7 is suspended at the bottom of the roller frame 3. A groove 8 is arranged vertically on the swaying rod 7. The groove 8 is slidably connected to one end of a slide rod 9. The slide rod 9 is arranged horizontally, and its axis is perpendicular to the axis of the smooth rods 2. The other end of the slide rod 9 is eccentrically mounted on a turntable 10. The turntable 10 is connected to a swaying motor 11, which is fixedly mounted on the base 1.

[0027] Soybeans are fed from the higher end of conveyor belt 5. The shaking motor 11 drives the turntable 10 to rotate. The turntable 10 drives the eccentrically mounted sliding rod 9 to rotate around the axis of the turntable 10. While the sliding rod 9 slides up and down in the chute 8, it drives the shaking rod 7 to move back and forth. Since the roller frame 3 is slidably mounted on the smooth rod 2, the shaking rod 7 drives the roller frame 3 to move back and forth, which in turn causes the conveyor belt 5 to shake back and forth. The conveyor belt 5 shakes back and forth on both sides of its inclined direction, so that the fed soybeans are evenly distributed on the surface of the conveyor belt 5. The roller motor 6 drives the conveyor belt 5 to move through the roller 4. The surface of the conveyor belt 5 moves along the side of its inclined direction. Since whole soybeans are close to spherical, they are easy to roll along the inclined direction of the conveyor belt 5, while broken soybeans are close to hemispherical and are not easy to roll. They will move along the side of the conveyor belt 5 in the inclined direction, which can separate the broken soybeans and avoid the broken soybeans remaining, which would affect the accuracy of the subsequent seed evaluation platform.

[0028] Specifically, in combination Figure 1 As shown, a support 12 is provided on the roller frame 3 at the higher end of the conveyor belt 5, and a receiving tray 13 is provided on the support 12. The receiving tray 13 is arranged parallel to the surface of the conveyor belt 5.

[0029] Soybeans are held in the receiving tray 13, making it easy to feed them onto the conveyor belt 5.

[0030] Specifically, in combination Figure 4 As shown, the receiving tray 13 has an opening 14 at its lower end, and the opening 14 is located at the rear end of the conveyor belt 5 in the conveying direction.

[0031] The receiving tray 13 feeds soybeans onto the conveyor belt 5 through the opening 14. The opening 14 is located at the rear end of the conveyor belt 5 in the conveying direction, which increases the distance that soybeans fall from the conveyor belt 5 to the side of its inclined direction, thus preventing whole soybeans from falling to the side of the conveyor belt 5 in the inclined direction.

[0032] Specifically, in combination Figure 4 As shown, a screen 15 is provided on the receiving tray 13.

[0033] After the receiving tray 13 is connected to the roller frame 3 via the bracket 12, the receiving tray 13 can shake with the roller frame 3. After soybeans are put into the receiving tray 13, the shaking screen 15 can screen the soybeans.

[0034] Specifically, in combination Figure 4 As shown, a first receiving box 16 is provided below the screen 15.

[0035] The first receiving box 16 receives the mud and other impurities screened out by the screen 15.

[0036] Specifically, in combination Figure 4 As shown, a baffle 17 is provided on the roller frame 3 at the rear end of the conveyor belt 5 in the conveying direction and outside the opening 14, and a second receiving box 18 is provided at the front end of the conveyor belt 5 in the conveying direction.

[0037] The baffle 17 prevents soybeans from falling off the side opposite to the direction of transport of the conveyor belt 5. The broken soybeans fall into the second receiving box 18 after the conveyor belt 5 moves to the side of its inclined direction.

[0038] Specifically, in combination Figure 4 As shown, a third receiving box 19 is provided at one of the lower ends of the conveyor belt 5.

[0039] Whole soybeans roll along the inclined direction of conveyor belt 5, and after falling off conveyor belt 5, they are collected in the third receiving box 19.

[0040] Specifically, in combination Figure 4 As shown, a feeding box 20 is also provided on the base 1, and a discharge port 21 is provided at the bottom of the feeding box 20. The discharge port 21 is located above the receiving tray 13.

[0041] The feeding box 20 can hold more soybeans at once, and the soybeans inside the feeding box 20 enter the receiving tray 13 through the discharge port 21.

[0042] Specifically, in combination Figure 4 As shown, the bottom of the feeding box 20 is provided with an auger 22, which is connected to the auger motor 23.

[0043] The auger motor 23 drives the auger 22 to rotate, and the auger 22 pushes the soybeans inside the feeding box 20 to the discharge port 21, which makes it easier to control the feeding speed of soybeans.

[0044] Specifically, in combination Figure 2 As shown, a support plate 24 is provided at the bottom of the conveyor belt 5, and the support plate 24 is fixedly connected to the roller frame 3.

[0045] The support plate 24 supports the conveyor belt 5, making the surface of the conveyor belt 5 flat and facilitating the rolling of soybeans.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
