DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.
[0019] Please refer to Figs. 1-3The utility model discloses an embodiment of a novel wheat seed circulation formula wind screen separator, including the air cylinder 1, the air cylinder 1 is hollow structure, and the both ends of air cylinder 1 are open structure, and the outer periphery of air cylinder 1 is installed with support frame 2, and the outer periphery of air cylinder 1 is installed with the containing cylinder 4, and the bottom of containing cylinder 4 is installed with straight cylinder 3, and the inner chamber of containing cylinder 4 is communicated with the inner chamber of straight cylinder 3, and the inner chamber of straight cylinder 3 is communicated with the inner chamber of air cylinder 1, and the inner wall of straight cylinder 3 is installed with the guide mechanism that extends to the outside of straight cylinder 3, and is fixedly connected with air cylinder 1, and the guide mechanism is used to put down after spreading wheat seed, and the air inlet end of air cylinder 1 is installed with the wind power mechanism.
[0020] In the embodiment: first, the wheat is added to the straight cylinder 3 and the containing cylinder 4, and then the power part of the fan mechanism and the guide mechanism is started, when the wind power mechanism is running, the suction force generated by the wind power mechanism sucks the external air into the air cylinder 1, forming a relatively rapid airflow flow;
[0021] When the power part of the guide mechanism is running, the guide mechanism orderly transports the wheat in the straight cylinder 3 downward, and spreads the wheat, so that the wheat falls naturally in a relatively thin state, at this time, the flowing air acts on the wheat, and the relatively light impurities (such as shells, dust, straw debris, etc.) contained in the wheat flow along the wind power under the action of the wind power, so that the relatively light impurities are blown out of the air cylinder 1.
[0022] Since the wheat falls naturally in a relatively thin state, the problem that the wind power loss is too large due to a large amount of wheat falling, or the problem that the impurities are not cleaned completely due to the mutual shielding of a large amount of wheat is avoided.
[0023] Please refer to Fig. 1 and Fig. 2 The wind power mechanism includes a filter screen 6 installed at the air inlet end of the air cylinder 1, one end of the filter screen 6 is installed with a rotating motor 7, the output shaft of the rotating motor 7 penetrates into the inner chamber of the air cylinder 1 and is coaxially connected with a fan blade 13, the output shaft of the fan blade 13 is rotationally connected to the connection part of the filter screen 6 through a bearing, and the filter screen 6 is in a porous structure.
[0024] In the embodiment: by starting the rotating motor 7, the rotating motor 7 drives the rotating fan blade 13 connected thereto to rotate, the rotating fan blade 13 forms a suction force to suck the external air into the air cylinder 1, and the external air is continuously sucked into the air cylinder 1, so that the impurities moving together with the air can be intercepted by the filter screen 6, avoiding the impurities from entering the air cylinder 1 again.
[0025] The bearing is arranged at the connection part of the filter screen 6 and the rotating motor 7, which can effectively reduce the resistance generated by the rotating motor 7 when running.
[0026] Please refer to Fig. 2 and Fig. 3The guiding mechanism comprises a baffle 11 fixedly installed in the inner cavity of the straight cylinder 3, the top end of the baffle 11 is integrally formed with a downwardly inclined guiding surface 12, the guiding mechanism further comprises a rotating roller 14 rotatably installed in the inner portion of the straight cylinder 3, the outer periphery of the rotating roller 14 is integrally formed with a plurality of outwardly protruding connecting plates 15 equidistantly arranged in the axial direction, the bottom end edge of the guiding surface 12 extends downwardly beyond the top end quadrant point of the rotating roller 14, and the guiding mechanism further comprises a driving motor 8 installed on the outer periphery of the wind cylinder 1, the output shaft of the driving motor 8 is fixedly connected with one end of the rotating roller 14 through a shaft coupling.
[0027] In the embodiment, when the driving motor 8 operates as the power part of the guiding mechanism, the driving motor 8 drives the rotating roller 14 connected with the output end of the driving motor 8 to rotate, at this time, the plurality of connecting plates 15 on the outer periphery of the rotating roller 14 synchronously rotate, at this time, the wheat slides downwardly under the guidance of the guiding surface 12, in the rotating process of the connecting plates 15, the wheat enters between two adjacent connecting plates 15, and then the wheat falls in a relatively thin state under the driving of the connecting plates 15, at this time, when the flowing wind force acts on the falling wheat, the relatively light impurities mixed in the wheat can flow outwardly along with the airflow, thereby realizing the wind force separation of the wheat and the relatively light impurities.
[0028] Please refer to Fig. 3 The inner wall of the wind cylinder 1 is symmetrically formed with a first inclined surface 9 and a second inclined surface 10, the wide opening of the first inclined surface 9 coincides with the wide opening of the second inclined surface 10, the outer periphery of the wind cylinder 1 is integrally formed with a downwardly protruding discharging opening 5, the inner cavity of the discharging opening 5 is communicated with the inner cavity of the wind cylinder 1, and the center line of the discharging opening 5 coincides with the wide opening edges of the first inclined surface 9 and the second inclined surface 10.
[0029] In the embodiment, part of the wheat can jump and displace in the falling process due to the contact with the inner wall of the wind cylinder 1, the displacement direction is random, and the wheat can displace towards the two ends of the wind cylinder 1, at this time, the first inclined surface 9 and the second inclined surface 10 can guide the falling wheat to fall into the discharging opening 5.
[0030] It should be noted that a receiving container should be placed at the position of the discharging opening 5 to avoid the problem of moisture caused by the direct falling of the wheat on the ground (there is accumulated water on the ground).
[0031] The above only describes the preferred embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
