Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seed selection devices, in particular to a device for screening sunflower seeds. Background Art
[0002] As an important economic crop, the quality of sunflower seeds is directly related to farmers' economic benefits and market competitiveness. The better the seed quality, the higher the quality of the sunflower. With the development of agricultural technology, the requirements for sunflower seed screening technology are getting higher and higher. However, traditional sunflower seed screening methods mainly rely on manual screening, which often has problems such as low efficiency, poor screening effect, and inability to accurately control. These problems not only increase farmers' labor intensity, but also affect the overall quality of sunflower seeds.
[0003] At present, in order to achieve the effect of convenient, fast and efficient screening of sunflower seeds, a mechanized screening device is usually used for screening operations. However, when the mechanized screening device is used, since it uses hard metal materials, such hard metal materials are easy to damage the seeds during the screening process, which will affect the survival rate of the seeds and bring inconvenience to the user. In view of this, we propose a device for screening sunflower seeds. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-Figure 4 The utility model provides a technical solution: a device for screening sunflower seeds, comprising a water selection box 1, a discharge hole 10 is arranged on one side plate of the water selection box 1, a water inlet pipe 11 is fixedly installed on one side plate of the water selection box 1 opposite to the discharge hole 10, and the water inlet pipe 11 is fed with water, which can promote the sunflower seeds floating on the water surface to flow toward the side of the discharge hole 10 better along with the water flow;
[0028] Specifically, a drop hopper 15 is fixedly installed on the hole wall of the discharge hole 10, a fan 3 is arranged on one side of the water selection box 1, an air outlet pipe 30 is fixedly installed at the air outlet end of the fan 3, a horizontal pipe 31 is fixedly installed at the end of the air outlet pipe 30, and a plurality of air blowing pipes 32 arranged at equal intervals are fixedly installed at the bottom of the horizontal pipe 31. The horizontal pipe 31 and the air blowing pipe 32 are both located in the water selection box 1, so as to allow air to enter, and utilize the air to escape in the water body in the form of bubbles, so as to promote the intact seeds to float better on the water surface;
[0029] Specifically, a rotating shaft 4 is rotatably connected between the front and rear side hole walls of the discharge hole 10, and a plurality of material-pickup plates 40 arranged in a ring with equal intervals are fixedly installed on the rotating shaft 4. A driving motor 41 is coaxially arranged at the end of the rotating shaft 4, and the driving motor 41 is fixedly installed on the water selection box 1. The end of the output shaft of the driving motor 41 is fixedly installed on the rotating shaft 4, so that the material-pickup plate 40 can be rotated to move the seeds floating on the water surface to the discharge hole 10 and drop them out from the drop hopper 15 to complete the unloading operation.
[0030] In this embodiment, a discharge hopper 12 is fixedly installed at the bottom of the water selection box 1, a discharge pipe 13 is fixedly installed at the bottom end of the discharge hopper 12, and a discharge valve 14 is fixedly installed on the discharge pipe 13, so that the discharge valve 14 can be opened to discharge sewage and discharge materials.
[0031] Specifically, the discharge hopper 15 is arranged to be inclined downward by 45° to 60° for smooth unloading operation.
[0032] Furthermore, the number of the material-push plates 40 is 2 to 6, and the material-push plates 40 are rotated to push the sunflower seeds to the discharge hole 10 and drop them onto the drop hopper 15 for unloading operation.
[0033] In addition, a collecting box 2 is provided at the end of the drop hopper 15, and a mesh box 22 is provided in the collecting box 2, and the mesh box 22 is used for containing seeds; a rectangular frame 21 is fixedly installed on the inner wall of the collecting box 2, and the mesh box 22 is placed on the upper surface of the rectangular frame 21, and a water outlet pipe 20 is fixedly installed on the side of the collecting box 2, and the water outlet pipe 20 is located below the rectangular frame 21, so as to facilitate the collection of seeds by the mesh box 22, and the excess water is discharged into the collecting box 2 and can be discharged outward along the water outlet pipe 20.
[0034] It is worth noting that handles 221 are fixedly mounted on the left and right side plates of the mesh box 22, and the handles 221 are used for holding operation.
[0035] When the device for screening sunflower seeds of the utility model is used, the discharge valve 14 is closed, the seeds are put into the water selection box 1, and the water inlet pipe 11 is connected to the external water pipe to allow water to enter the water selection box 1. Since the intact seeds are hollow inside, the intact seeds can float on the water surface, and the damaged seeds will cause water to enter the inside, and the damaged seeds will settle to the bottom of the water body. As the water body liquid level rises to be flush with the discharge hole 10, the water inlet pipe 11 can drive the seeds floating on the water surface to flow along with the water flow. When the sunflower seeds flow to the discharge hole 10, the drive motor 41 is connected to an external power supply and made to work. When the drive motor 41 works, the output shaft thereof rotates to drive the rotating shaft 4 and the material-diverting plate 40 to rotate, so that the sunflower seeds flowing to the discharge hole 10 are diverted to fall from the discharge hole 10 to the drop hopper 15. In addition, after the seeds fall into the mesh box 22 along with the water along the drop hopper 15, the mesh box 22 collects the seeds, and the water drips into the collection box 2 along the mesh box 22 and is discharged outward along the water outlet pipe 20.
[0036] When necessary, the fan 3 can be connected to an external power source and made to work. When the fan 3 works, air is blown into the water selection box 1, and the gas is discharged in the form of bubbles in the water body, which can promote the intact seeds to float better on the water surface.
