Specific implementation
[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.
[0027] Please refer to Figures 1-5 , a rice vibrating air separation device, including a case 1, the case 1 is internally provided with a feed channel 11 and a miscellaneous material groove 12 that are communicated with each other, the feed channel 11 is provided with a material distribution assembly, and the case 1 is provided with an air separation mechanism and a vibrating mechanism; the air separation mechanism includes a fan 2 arranged at one side of the feed channel 11, the case 1 is internally provided with a first air duct 21, both ends of the first air duct 21 are communicated with the feed channel 11, the first air duct 21 is provided with a first filter screen 22 close to the end portion, the case 1 is further internally provided with a second air duct 23 communicated with the feed channel 11, the second air duct 23 is further provided with a second filter screen 24 at the end portion, and the case 1 is provided with a screening assembly on the lower side of the second air duct 23. An air inlet is arranged on the case 1 opposite to the first air duct 21, and a baffle (not shown in the figure) can be arranged in the first air duct 21 to weaken the wind force and prevent the rice from being sucked into the first air duct 21.
[0028] Through the air separation mechanism, after the material passes through the material separation assembly, the fan 2 draws light impurities (fibrous impurities, rice straw, rice husks, etc.) in the rice into the first air duct 21. After further impurity removal by the vibrating screen 3, the material falls along the feed channel 11 under the action of gravity. The air in the first air duct 21 passes through the first filter 22 and blows the impurities in the material into the second air duct 23. Before passing through the vibrating screen 3, the material is initially cleaned of impurities by the air separation mechanism. The first air duct 21, which is connected to the feed channel 11, is used to perform a secondary impurity removal on the material after passing through the vibrating screen 3. During the secondary impurity removal process, the rice is separated from the gravel under the action of wind. Since rice of different weights travel different distances, the rice can be initially screened to distinguish different rice grades.
[0029] In an embodiment further provided by the present invention, the vibration mechanism includes a vibrating screen 3 , a vibration motor 31 is provided at the lower part of the vibrating screen 3 , a first sewage discharge channel 32 is opened at the lower side of the chassis 1 , and impurities filtered by the vibrating screen 3 fall into the first sewage discharge channel 32 .
[0030] In an embodiment further provided by the present invention, the screening assembly includes a first discharge port 4, a second discharge port 41, and a second sewage discharge channel 42 continuously arranged on the lower side of the second air duct 23, and the second sewage discharge channel 42 is connected to the miscellaneous material trough 12. Under the action of wind, the rice is separated from the gravel, and since the moving distances of rice of different weights are different, the rice can be initially screened to distinguish different rice grades, wherein the gravel still passes along the feed until it falls into the miscellaneous material trough 12, the fuller and heavier rice falls into the first discharge port 4, and the shriveled and lighter rice falls into the second discharge port 41, and the impurities in the rice enter the miscellaneous material trough 12 through the second sewage discharge channel 42, and the wind flows out from the second filter screen 24.
[0031] In an embodiment further provided by the present invention, the first drain channel 32 and the second drain channel 42 are connected, that is, the impurities filtered by the vibrating screen 3 pass through the first drain channel 32 and the second drain channel 42 in sequence until they fall into the miscellaneous material trough 12 .
[0032] In a further embodiment provided by the present invention, the material separation assembly includes a plurality of connecting blocks 5, each of which forms a continuous V-shaped channel 51. When the material passes through the continuous V-shaped channel 51, the material throughput in the same plane per unit time is increased, thereby improving the impurity removal efficiency of the air separation mechanism.
[0033] In an embodiment further provided by the present invention, the cross-section of the V-shaped channel 51 is larger at the top and smaller at the bottom. This arrangement makes the process of materials falling from the feed channel 11 into the V-shaped channel 51 smoother, and is more conducive to the passage of materials than the design of upper and lower straight grooves.
[0034] The further provided embodiment of the utility model further provides that the feed channel 11 at the lower end of the vibrating screen 3 is provided with a material distribution assembly, which has similar functions with the above-mentioned assembly, and is used to improve the material passing capacity of the vertical plane of the wind direction per unit time.
[0035] The further provided embodiment of the utility model further provides that the first sundry box 6 is arranged at the end of the first air duct 21, and the second sundry box 61 is matched with the sundry groove 12, so that the impurities in the first air duct 21 fall into the first sundry box 6, and the gravel and other materials in the second air duct 23, the vibrating screen 3 and the feed channel 11 fall into the second sundry box 61, thereby avoiding the influence of the dust in the workshop on the workers and the surrounding environment.
[0036] Working principle:
[0037] The light impurities (fiber impurities, rice straw and rice husk) in the rice are sucked into the first air duct 21 by the fan 2 after the material passes through the material distribution assembly, the material is further decontaminated by the vibrating screen 3, and then falls along the feed channel 11 under the action of gravity, and the air in the first air duct 21 blows the impurities in the material into the second air duct 23 after passing through the first filter screen 22. The material is preliminarily decontaminated by the winnowing mechanism before passing through the vibrating screen 3, the material is secondarily decontaminated by the first air duct 21 connected with the feed channel 11 after passing through the vibrating screen 3, the rice is separated from the gravel under the action of the wind in the secondary decontamination process, and the rice is preliminarily screened according to the different moving distances of the rice with different weights, so as to distinguish different grades of rice. The gravel still falls into the sundry groove 12 along the feed channel, the full and heavy rice falls into the first discharge port 4, the dry and light rice falls into the second discharge port 41, the impurities in the rice fall into the sundry groove 12 through the second blow-off channel 42, and the air flows out from the second filter screen 24.
[0038] The above only describes some exemplary embodiments of the utility model by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the utility model for ordinary skilled persons in the art. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the utility model claims.
