[0002] As an important global food and oilseed crop, soybean breeding is of great significance for increasing soybean yield, improving quality, and enhancing stress resistance.

[0003] In the screening device for soybean breeding with announcement number CN219253235U, the utility model discloses a screening device for soybean breeding, which includes a frame, a vibration generating device, a screening structure, a sliding shaft and a spring; when screening soybean seeds, the soybeans are poured into the screening structure so that the soybeans are spread on the screening grid, and then the vibration generating device is activated. The vibration generated by the vibration generating device is transmitted to the entire screening structure through the screening structure.

[0004] The screening device for soybean breeding described above screens soybean seeds through a screening structure. However, the screening structure in the device can only screen seeds of the same size, which wastes some seeds. Furthermore, it cannot select out diseased seeds during the screening process, and the screened seeds need to be screened again for diseases, which increases the workload. Therefore, a screening device for crop breeding is proposed to address the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a screening device for crop breeding, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A screening device for crop breeding includes a box, a screening structure and a vibration structure located inside the box, and two discharge mechanisms located on the left and right sides of the box.

[0008] A feed hopper is fixedly connected to the upper right side of the box body. Two fixed grooves are provided on the front and rear walls of the box body. A discharge port is provided on the left wall of the box body corresponding to the two upper fixed grooves and on the right wall corresponding to the two lower fixed grooves. A sliding groove is provided at the lower front end of the box body, and a collection box is slidably connected inside the sliding groove.

[0009] Preferably, the screening structure includes a first screen plate and a second screen plate, wherein a plurality of springs are fixedly connected to the front upper part and the rear upper part of the first screen plate and the front upper part and the rear upper part of the second screen plate.

[0010] Preferably, the first sieve plate is located between the two upper fixed grooves, and the second sieve plate is located between the two lower fixed grooves.

[0011] By adopting the above technical solution, the fixing groove can limit the screen plate and prevent the screen plate from falling off the box body during vibration.

[0012] Preferably, several of the springs are fixedly connected to the upper wall of the four fixing slots respectively.

[0013] By adopting the above technical solution, several springs can reset the sieve plate after it bounces up, enabling the sieve plate to have the ability to reciprocate.

[0014] Preferably, the vibration structure includes a motor and a first fixed rod. The output end of the motor is fixedly connected to a second fixed rod. Triangular blocks are inserted and fixedly connected to the front and rear of the outer surface of the second fixed rod and the front and rear of the outer surface of the first fixed rod. A linkage wheel is fixedly connected to the front end of the first fixed rod and the front end of the second fixed rod. A belt is engaged with the outer surfaces of the two linkage wheels.

[0015] Preferably, the motor is fixedly connected to the rear end of the housing, and the motor output end passes through the rear end of the housing. The first fixing rod is located on the lower left side of the second sieve plate, and the rear end of the first fixing rod is movably connected to the rear wall of the housing.

[0016] Preferably, the second fixing rod is located on the lower right side of the first sieve plate, and both the second fixing rod and the first fixing rod are movably connected to the front end of the box body, and both of the linkage wheels are located outside the box body.

[0017] By adopting the above technical solution, the two fixed rods located at the bottom of the two sieve plates can achieve the vibration effect of the two sieve plates by rotating the external triangular blocks, which facilitates the sieving of seeds on the upper part of the two sieve plates.

[0018] Preferably, the discharge mechanism includes a triangular box, with a feed inlet at one end of the triangular box near the housing, a whole seed discharge pipe fixedly connected to the lower end of the triangular box, a support block fixedly connected to one end of the whole seed discharge pipe near the housing, a disease discharge pipe fixedly connected to the upper rear end of the whole seed discharge pipe, and an air inlet fixedly connected to the upper front end of the whole seed discharge pipe.

[0019] Preferably, the triangular box is fixedly connected to the housing, and the support block is in close contact with the housing.

[0020] By adopting the above technical solution, the collection box in the upper part of the discharge mechanism is set into a triangular structure, which can facilitate the collection of discharged seeds, while the support block can support the entire discharge mechanism and prevent the connection between the discharge mechanism and the box from loosening during use.

[0021] Preferably, the inlet and outlet are located in the same position, and the air inlet and the disease discharge pipe are located in the same position.

[0022] By adopting the above technical solution, the air inlet and the disease discharge pipe are positioned in a corresponding manner, which makes it convenient for the fan to blow the disease into the disease discharge pipe for screening the disease in the seeds after screening.

[0023] The beneficial effects of this utility model are:

[0024] 1. This utility model provides a screening device for crop breeding. The device has two sieve plates with different gaps in its screening structure, and a vibration structure is installed under both sieve plates. When in use, seeds entering the box through the feed hopper first fall onto the first sieve plate in the screening structure. The vibration structure causes seeds smaller than the sieve plate gaps to fall, while seeds larger than the sieve plate slide out of the box, completing the screening. The fallen seeds then undergo a second screening via the second sieve plate, further improving seed utilization. Seeds that pass through the sieve completely and cannot be used for breeding can be collected in a collection box and used as raw materials for other products.

[0025] 2. This utility model provides a screening device for crop breeding. By setting a discharge mechanism at the discharge port on both the left and right sides of the box, after the seeds are screened and discharged by the screening structure, the seeds will slide into the discharge mechanism. When the seeds fall in the discharge mechanism, the fan in the discharge mechanism will blow air towards the diseased seed discharge pipe. The diseased seeds in the falling seeds are lighter than normal seeds due to disease damage. Blown by the fan at a specific wind speed, the diseased seeds will drift into the diseased seed discharge pipe and slide out, while normal seeds will be discharged through the whole seed discharge pipe. This realizes the disease screening of the screened seeds, which can accelerate the seed screening work and reduce the amount of labor. Attached Figure Description

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] Specific implementation examples are given below.

[0038] Please see Figures 1-7 This utility model provides a screening device for crop breeding, including a box 1, a screening structure 6 and a vibration structure 7 located inside the box 1, and two discharge mechanisms 5 located on the left and right sides of the box 1.

[0039] A feed hopper 2 is fixedly connected to the upper right side of the box body 1. Two fixed grooves 3 are provided on the front and rear walls of the box body 1. A discharge port 4 is provided on the left wall of the box body 1 corresponding to the position of the upper two fixed grooves 3 and on the right wall corresponding to the position of the lower two fixed grooves 3. A sliding groove 8 is provided at the lower front end of the box body 1. A collection box 9 is slidably connected inside the sliding groove 8.

[0040] Furthermore, such as Figures 4-6As shown, the screening structure 6 includes a first screen plate 61 and a second screen plate 62. Several springs 63 are fixedly connected to the front and rear upper parts of the first screen plate 61 and the front and rear upper parts of the second screen plate 62, respectively. The first screen plate 61 is located between two upper fixed grooves 3, and the second screen plate 62 is located between two lower fixed grooves 3. Several springs 63 are fixedly connected to the upper walls of the four fixed grooves 3. The vibration structure 7 includes a motor 71 and a first fixed rod 72. A second fixed rod 73 is fixedly connected to the output end of the motor 71. The front and rear outer surfaces of the second fixed rod 73 are connected to the front and rear outer surfaces of the first fixed rod 72. Triangular blocks 74 are fixedly connected to each part. The front ends of the first fixed rod 72 and the second fixed rod 73 are fixedly connected to the linkage wheel 75. The outer surfaces of the two linkage wheels 75 are engaged with the belt 76. The motor 71 is fixedly connected to the rear end of the box body 1, and the output end of the motor 71 passes through the rear end of the box body 1. The first fixed rod 72 is located on the lower left side of the second screen plate 62, and the rear end of the first fixed rod 72 is movably connected to the inner rear wall of the box body 1. The second fixed rod 73 is located on the lower right side of the first screen plate 61, and both the second fixed rod 73 and the first fixed rod 72 are movably connected to the front end of the box body 1. The two linkage wheels 75 are located outside the box body 1.

[0041] The above scheme involves setting two sieve plates with different gaps in the screening structure 6 of the device, and setting a vibration structure 7 at the bottom of the two sieve plates. When the device is in use, the seeds entering the box 1 through the feed hopper 2 will first fall on the first sieve plate 61 in the screening structure 6. Through the vibration of the vibration structure 7, the seeds smaller than the gap of the sieve plate will fall, and the seeds larger than the sieve plate will slide out of the box 1 after vibration to complete the screening. The fallen seeds will be screened again through the second sieve plate 62 in the screening structure 6 to complete the secondary screening of the seeds, which can improve the seed utilization rate.

[0042] Furthermore, such as Figure 7 As shown, the discharge mechanism 5 includes a triangular box 51. A feed inlet 52 is provided at one end of the triangular box 51 near the housing 1. A whole seed discharge pipe 53 is fixedly connected to the lower end of the triangular box 51. A support block 54 is fixedly connected to one end of the whole seed discharge pipe 53 near the housing 1. A disease discharge pipe 55 is fixedly connected to the upper rear end of the whole seed discharge pipe 53. The triangular box 51 is fixedly connected to the housing 1. The support block 54 is in close contact with the housing 1. The feed inlet 52 corresponds to the discharge outlet 4. The air inlet 56 corresponds to the disease discharge pipe 55.

[0043] Through the above scheme: when the seeds fall in the discharge mechanism 5, the fan 57 in the discharge mechanism 5 will blow air towards the diseased seed discharge pipe 55. The diseased seeds in the falling seeds are lighter than normal seeds due to disease damage. Blown by the specific wind speed of the fan 57, the diseased seeds will drift into the diseased seed discharge pipe 55 and slide out, while normal seeds will be discharged through the whole seed discharge pipe 53, thereby realizing the disease screening of the screened seeds.

[0044] Working Principle: This utility model provides a screening device for crop breeding. Its core lies in its unique screening and disease detection mechanism. The device has a built-in dual screening system, namely, two sieve plates (first sieve plate 61 and second sieve plate 62) with different apertures are set in the screening structure 6. They are connected to the vibration structure 7 below. During operation, the seeds fall into the box 1 from the feed hopper 2. They first encounter the screening of the first sieve plate 61. With the help of the vibration structure 7, the seeds smaller than the sieve aperture naturally fall to the second sieve plate 62 for secondary subdivision, ensuring more accurate seed grading and improving seed utilization. Seeds that exceed the screening range slide out of the box 1 along a specific path, completing the initial screening.

[0045] For seeds passing through the sieving structure 6, this device also cleverly incorporates a disease screening function. Discharge mechanisms 5 are installed at the discharge ports 4 on both sides of the housing 1. When the seeds are screened and flow into the discharge mechanism 5, the built-in fan 57 starts working, blowing airflow at a customized speed towards the disease discharge pipe 55. Since diseased seeds are relatively light due to disease erosion, they will be deflected into the disease discharge pipe 55 and discharged under the action of the wind. Conversely, healthy seeds maintain their original trajectory and are smoothly discharged through the whole seed discharge pipe 53. This design not only accelerates the overall seed screening process but also significantly reduces the burden of manual screening, realizing automated and efficient seed screening and disease identification.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
