Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed seed screening, in particular to a rapeseed seed screening device. Background Art

[0002] Rapeseed seeds, also known as Brassica seeds, are the seeds of the cruciferous crop rapeseed. They are mainly used for making edible oil and planting. When the rapeseed matures, pods will form after the flowers fall. When the pods are about to crack, you can break open the pods and take out the seeds to get rapeseed seeds.

[0003] After rapeseed seeds are harvested, or before planting and oil production, they generally need to be screened before processing. Common screening methods now include wind separation and sieves. The different apertures of the sieves can be used to remove impurities of varying weights and sizes and seeds damaged by pests and diseases. Wind separation can separate impurities and seeds damaged by pests and diseases through the action of wind, thereby ensuring the quality and yield of the screened rapeseed seeds.

[0004] At present, the wind selection equipment commonly used in agriculture is used to screen rapeseed seeds. The wind is used to generate wind manually or electrically, and the fallen seeds are blown away by the wind. Then the full seeds, bad seeds and impurities are collected in different places.

[0005] However, when in use, a large amount of wind and extremely light dust and impurities will be blown out from the tail end of the device, which not only affects the surrounding environment, but also makes it inconvenient for subsequent cleaning, causing inconvenience to the user. At the same time, it is also inconvenient to control the seed leakage speed. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0039] A rapeseed seed screening device comprises a housing 10, a feeding hopper 11 is arranged on the top of the housing 10, and the housing 10 and the feeding hopper 11 are structures of existing rapeseed seed screening equipment;

[0040] In the examples of this application, please refer to Figure 1 and 2 A fan 20 is arranged inside the shell 10, a material control switch 40 is arranged between the shell 10 and the feed hopper 11, and a switch 30 electrically connected to the fan 20 and the material control switch 40 is arranged on the front of the shell 10. The switch 30 can be set to an existing button switch, a travel switch or an electronic switch as needed. The fan 20 can adopt the existing one, and can be connected, controlled and driven in the existing way. After the normal seeds fall, the wind generated by the fan 20 can screen the rapeseed seeds according to the existing wind selection distance.

[0041] Furthermore, the above-mentioned material control switch 40 includes a fixed shell 41 fixed to the top of the outer shell 10, and a motor 42 electrically connected to the switch 30 is fixed on the side of the fixed shell 41. The motor 42 is preferably a stepping motor, and other types of existing motors can also be set as needed. The output shaft of the motor 42 is fixed with a threaded rod 43 rotatably arranged inside the fixed shell 41, and the external thread of the threaded rod 43 is sleeved with a movable block 44. The movable block 44 is fixedly connected with a valve plate 45 that slides and extends to the bottom end of the feed hopper 11. When in use, starting the motor 42 can drive the threaded rod 43 to rotate, thereby driving the movable block 44 to slide along the threaded rod 43, thereby driving the valve plate 45 to slide, so that the opening of the bottom end of the feed hopper 11 can be controlled, and then the leakage speed can be controlled to adapt to different usage requirements.

[0042] Meanwhile, in further embodiments, please refer to Figure 1 and 3 A protective plate 50 is provided on the left side of the housing 10. The protective plate 50 and the fan 20 are located at both ends of the housing 10. Specifically, the protective plate 50 includes a movable plate 51 rotatably provided on the side of the housing 10 through a rotating shaft. The rotating end of the movable plate 51 is located at the top. A filter screen 52 is embedded inside the movable plate 51. A handle 53 is fixed on the side of the movable plate 51. When in use, the blown wind will be blown out through the filter screen 52, and impurities and waste will be blocked by the filter screen 52. Finally, the waste will fall down into the material receiving structure 60 below.

[0043] For further examples, see Figure 1 and 3 The material receiving structure 60 includes a fixed frame 61 movably disposed inside the housing 10, and the fixed frame 61 is located at the bottom end of the movable plate 51. Figure 3 As shown, a receiving basket 62 is fixed to the bottom of the fixed frame 61 for receiving impurities, and a plug-in block 63 is fixed to the side of the fixed frame 61. The plug-in block 63 is plugged into the interior of the shell 10. A slide groove is provided on the inner wall of the shell 10, and the slide groove is opened inward from the side of the shell 10. A slider 64 is fixed to the side of the fixed frame 61, and the slider 64 is adapted to the slide groove. When the fixed frame 61 and the receiving basket 62 need to be removed, the movable plate 51 and the filter screen 52 are turned, and then the fixed frame 61 and the receiving basket 62 are slid to the left, so that the slider 64 is away from the slide groove, and the plug-in block 63 is away from the shell 10. Then the fixed frame 61 and the receiving basket 62 can be removed, and vice versa, they can be installed.
