This equipment selects varieties with excellent traits by conducting multi-faceted testing and screening on seeds, providing better germplasm resources for agricultural production. Similarly, for crops such as Trichosanthes seeds that require seeds for planting, breeding needs to be screened before planting to ensure that the crops planted have good yields and quality.

However, the traditional method cannot guarantee the state of the seeds when being blown. The contact surface between the seeds and the airflow will directly affect whether the seeds can be screened by blowing. If the contact surface is too small, it is impossible to distinguish the good and bad seeds under the influence of the airflow. Utility Model Content

DETAILED DESCRIPTION
[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a breeding and screening device for Trichosanthes seeds, comprising:
[0025] The machine body 1 is provided with a sieve plate 2, a No. 1 collection box 3 and a No. 2 collection box 4 are fixedly connected to the bottom surface of the machine body 1, and a screening component is provided. The screening component includes a motor 5 fixedly connected to the side wall of the machine body 1 through a bracket, and the output end of the motor 5 is fixedly connected to a No. 1 rotating shaft 6, and the No. 1 rotating shaft 6 is rotatably connected to the inner wall of the machine body 1 through a bearing. Four sleeves 7 are fixedly connected to the edge of the upper surface of the No. 1 collection box 3 at equal distances, and the four sleeves 7 are all slidably connected to support rods 8, and springs 9 are fixedly connected between the four sleeves 7 and the four support rods 8, and the tops of the four support rods 8 are fixed to the bottom surface of the sieve plate 2. The first rotating shaft 6 is fixedly connected to the end away from the motor 5 with a cam 10, and the upper surface of the sieve plate 2 is fixedly connected with a blocking plate 19. The cam 10 is located below the sieve plate 2, and the circumferential side wall of the cam 10 fits with the bottom surface of the sieve plate 2, so that after the cam 10 rotates, it can push the sieve plate 2 to move up and down. The surface of the sieve plate 2 is provided with a plurality of sieve holes, and the plurality of sieve holes are all strip-shaped vertical grooves. By limiting the shape and size of the sieve holes, the breeding can be well screened. At the same time, through such strip-shaped holes, the seeds that are screened out can cooperate with the subsequent sorting work with a larger contact surface;
[0026] The sorting component is arranged in the body 1, and the sorting component includes a second rotating shaft 11 and a third rotating shaft 12 arranged in the body 1. The second rotating shaft 11 and the third rotating shaft 12 are both rotatably connected to the side wall of the body 1 through bearings. The second rotating shaft 11 and the third rotating shaft 12 are circumferentially fixedly connected to the driven wheel 13 at one end close to the motor 5, and the first rotating shaft 6 is fixedly connected to the driving wheel 14 at one end close to the motor 5. Belts 15 are wound between the driving wheel 14 and the two driven wheels 13. The second rotating shaft 11 and the third rotating shaft 12 are fixedly connected to the driven wheel 13 at one end away from the motor 5. A blowing fan blade 16 is connected, and a plurality of ventilation slots 17 are provided on the side wall of the body 1. The plurality of ventilation slots 17 are equidistantly arranged around the No. 2 rotating shaft 11 and the No. 3 rotating shaft 12, respectively, to facilitate the circulation of internal airflow, so that the blowing fan blade 16 can generate airflow well. The side walls of the No. 1 collecting box 3 and the No. 2 collecting box 4 are in close contact, and a slope 18 is provided on the edge of the side wall of the No. 1 collecting box 3. The bottom height of the slope 18 is greater than the height of the No. 2 collecting box 4, so that the sorted bad seeds will not adhere to the edge of the surface of the No. 1 collecting box 3, and can also prevent the bad seeds from accidentally falling into the No. 1 collecting box 3.
[0027] The detailed working process of the utility model is as follows:
[0028] When in use, firstly, the seeds to be screened are placed on the surface of the sieve plate 2 and inside the blocking panel 19. The blocking panel 19 can protect the seeds from flying around when the screening component is working. After completion, the motor 5 is started, and the motor 5 drives the No. 1 rotating shaft 6 to rotate, thereby driving the cam 10 to rotate. The cam 10 will reciprocately lift the sieve plate 2 upward for a short distance according to the rotation speed of the No. 1 rotating shaft 6. With the action of the spring 9, when the sieve plate 2 is reciprocated and vibrates, the vibration is made more disordered, so that the seeds on the surface of the sieve plate 2 can be efficiently and quickly screened out through the sieve holes. Those that are not full enough or very deflated will directly fall through the sieve holes, and those left on the surface of the sieve plate 2 are good seeds.
[0029] However, the shapes of seeds are diverse, and it cannot be guaranteed that those that are not full are not good varieties. A subsequent sorting component is needed to conduct another screening. The second screening is carried out by quality. The No. 1 shaft 6 rotates, thereby driving the driving wheel 14 to rotate. Through the transmission of the belt 15, the two driven wheels 13, the No. 2 shaft 11 and the No. 3 shaft 12 are driven to rotate, and then the two blowing fan blades 16 are driven to rotate. The airflow generated by the rotating blowing fan blades 16 is used to further screen the fallen seeds. The fallen seeds are affected by the shape of the sieve holes and always contact the airflow with a larger contact surface, so that the sorting component can work accurately and efficiently. The large seeds continue to fall down to the No. 1 collection box 3, and the light seeds are blown into the No. 2 collection box 4 by the airflow to achieve further sorting. Cooperating with the screening component, the subsequent sorting is more accurate, and the efficiency and accuracy of screening are improved.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
