[0002] In agricultural production, seed quality and germination rate are important factors affecting crop yield. Spinach is a common vegetable with high nutritional value. During the autumn harvest season, spinach seeds harvested from the fields contain a large amount of impurities, including dust, gravel, and stems and leaves. Failure to promptly remove these impurities can significantly affect seed quality and even germination rate. Furthermore, freshly harvested seeds require a certain amount of storage after cleaning. However, if the seeds are too moist or have become attached to wet soil, they can become moldy and deteriorate during storage, reducing germination rate. Therefore, preliminary seed drying is essential. However, traditional seed screening and drying methods often involve separate processes, resulting in low efficiency and difficulty ensuring seed quality and germination rate. Therefore, a device is needed to simply dry spinach seeds after careful screening, preventing them from becoming moldy and deteriorating during storage. This is crucial for improving agricultural production efficiency. Utility Model Content

In order to realize the vibration movement and provide supporting force, the bottom of both sides of the first vibrating screen 6 and the second vibrating screen 8 are fixedly connected with a buffer seat 5. In order to dry and collect the selected seeds and flow them into the chain conveyor 13, a pressing plate 17 is hinged at one end of the second vibrating screen 8 that is inclined downward, and an ash receiving pan 10 that is inclined downward is fixedly connected to the bottom. The ash receiving pan 10 can collect fine sand and dust. One end of the ash receiving pan 10 passes through the side wall of the screening box 1, and the bottom of the other end is fixedly connected to the buffer seat 5, and the ash outlet of the ash receiving pan 10 is set behind the screening box 1. In order to dry the screened seeds, a chain conveyor with an inclined upward direction is provided below the ash receiving pan 10. Plate conveyor 13, one end of the chain plate conveyor 13 extends to the outside of the screening box 1 and is rotatably connected to the bracket 12, the bracket 12 is fixedly connected to the outside of the screening box 1 through the support platform 21, in order to facilitate collection and packaging, a discharge port 11 is fixedly connected to one side of the support platform 21, and the discharge port 11 is set on the left side of the right side of the screening box 1, and is offset from the outlet of the first vibrating screen 6. In order to provide power support for the drying function, a hot air blower 16 is fixedly connected to the outside of the screening box 1, and the hot air blower 16 is connected to the bellows 14 arranged at the bottom of the screening box 1 through an air duct. A number of air outlets 15 are opened on the bellows 14, and the air outlets 15 are evenly arranged on the bellows 14.

[0020] It should be noted that the chain conveyor 13 in the present invention is an existing mature technology, and the power device of the chain conveyor 13 will not be described in detail.

[0021] In order to provide support for the vibrating part and realize vibrating movement, the buffer seat 5 includes a spring 51 and a boss 52. The lower end of the spring 51 is fixedly connected to the boss 52. The first vibrating screen 6, the second vibrating screen 8, and the ash receiving tray 10 are all connected to the upper end of the spring 51. The boss 52 is fixedly connected to the inner wall of the screening box 1.

[0022] In order to allow the blown-out broken, shrunken and lighter impurities to flow out and to allow air to circulate, an opening is provided on the side of the screening box 1 opposite to the induced draft fan 4 to the bottom of the first vibrating screen 6 .

[0023] In order to ensure that the seeds falling onto the chain conveyor 13 can be evenly spread thereon and can be fully and evenly dried by hot air, the chain conveyor 13 is provided with through holes 23 and strip-shaped bosses 22 .

[0024] In order to control the opening angle of the pressing plate 17 and the falling speed of the seeds, a knob 18 is rotatably connected to the outside of the screening box 1 , and the knob 18 passes through the side wall of the screening box 1 and is connected to the hinge of the pressing plate 17 .

[0025] The specific working process of this utility model is as follows:

[0026] When collecting spinach seeds grown on a large scale, put them with sand, soil, stems and leaves, as well as damaged and shriveled seeds from the feed port 2. The rotating roller 3 with a baffle rotates evenly to drive the seeds containing impurities to fall into the screening box 1. At the same time, the induced draft fan 4, the first vibrating motor 7, and the second vibrating motor 9 are started. The wind force of the induced draft fan 4 blows out the lighter impurities and damaged and shriveled seeds from the right opening, and the remaining seeds with impurities fall onto the first vibrating screen 6. After vibration screening, the seeds and small particles of impurities fall onto the second vibrating screen 8 below. The larger stones and impurities are discharged through the outlet on the right side of the first vibrating screen 6. The smaller impurities and dust that pass through the vibration of the second vibrating screen 8 fall into the ash receiving tray 10 below, and the ash receiving tray is driven by the vibration of the second vibrating motor 9. 10 vibrates, thereby sending smaller impurities out of the ash outlet of the ash receiving tray 10, and the good seeds after screening slowly flow into the chain conveyor 13 from the gap between the pressure plate 17 at the left end of the second vibrating screen 8 and the inner wall of the screening box 1. By adjusting the external knob 18, the gap between the pressure plate 17 and the inner wall of the screening box 1 can be controlled, thereby controlling the speed of the seeds falling. At this time, the chain conveyor 13 is turned on, and the seeds will not be stacked together due to the strip boss 22, and will be slowly transported by the chain conveyor 13 to the outer discharge port 11 for collection. At the same time, the hot air blower 16 is started, and the hot air from the hot air blower 16 enters the wind box 14 through the air duct and blows upward through the air outlet 15 on the wind box 14. The hot air is evenly blown onto the seeds through the through holes 23 on the chain conveyor 13 for drying. Screening and drying spinach seeds according to the above steps can more accurately select good seeds, facilitate the storage of seeds without mold and deterioration, and improve work efficiency and seed germination rate.
