[0037] 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 of the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description clearly, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0039] like Figure 1-5 As shown, a multifunctional combined rice cleaning screen device comprises: an air separation box 1; a staggered air duct 2; a feeder 3; an auger 4; a drive motor 5; a vibrating screen 6; a first fan 7; a negative pressure dust collector 8; a brake dragon 9; a second fan 10; a walking bracket 11; a walking wheel 12; Figure 4As shown, a staggered air duct 2 is provided inside the air separation box 1, and the overall shape of the air separation box is rectangular. The top air outlet of the staggered air duct 2 is fixedly connected to a feeder 3, a vibrating screen 5 is located below the air separation box 1, and the feed hopper of the vibrating screen 6 is connected to the discharge port at the bottom of the staggered air duct 2; the first fan 7 is located at the rear side of the bottom of the air separation box 1, and the air delivery port of the first fan is connected to the staggered air duct 2. The negative pressure dust collector 8 is located on one side of the air separation box 1, and the dust suction port of the negative pressure dust collector 8 is connected to the staggered air duct 2 through a pipeline;

[0040] In this embodiment, the staggered air duct 2 is designed to allow the material to flow longer when passing through the box body, and will not fall directly into the vibrating screen 5 at the bottom. In this way, when the first fan 7 is started, the fan air enters the staggered air duct 2, and the input air flow flows upward along the air duct, blowing up the lighter bran and dust in the material. Because the bran and dust blown up by the staggered air duct 2 will stay in the air duct for a longer time, at this time, when the negative pressure dust collector 8 above the air separation box 1 is started, suction will be generated above the staggered air duct 2, and the suction airflow will flow downward along the air duct, sucking all the bran and dust into the negative pressure dust collector 8.

[0041] In this embodiment, Figure 5 As shown, in order to completely separate the bran from the dust, a negative pressure dust collector 8 is arranged on one side of the air separation box 1, and the dust suction port of the negative pressure dust collector 8 is connected with the staggered air duct 2 through a pipe, the brake dragon 9 is located at the rear side of the bottom of the negative pressure dust collector 8, and the dust suction port of the brake dragon 9 is connected with the dust removal port at the bottom of the negative pressure dust collector 8 through a pipe, the second fan 10 is located on the right side of the top of the brake dragon 9, the dust suction port of the second fan 10 is fixedly connected with the air outlet of the negative pressure dust collector 8 through a pipe, and the dust removal fan on the side of the second fan 10 is fixedly connected with the dust exhaust pipe of the brake dragon 9 through a pipe. When bran and dust enter the negative pressure dust collector 8, smaller particles of dust will be directly sucked into the top of the negative pressure dust collector 8 and enter the second fan 10 along the air duct for dust removal, while larger particles of dust and bran will be adsorbed by the filter bags of the negative pressure dust collector. When the filter bags accumulate to a certain level, the negative pressure dust collector releases the pressure, and the bran and large particles of dust on the surface of the filter bags are driven into the dust removal port. The material is sucked into the brake drum along the dust removal port pipe. The brake drum screens the bran and large particles of dust, and the large particles of dust enter the fan for dust removal from the brake drum dust exhaust pipe. The screened bran is poured out from the brake drum discharge port.

[0042] The specific operating principle is as follows: start the drive motor 5, the electric energy drives the output end of the drive motor 5 to rotate, the output end rotates and drives the auger 4 to rotate, the material is poured into the feeder 3, the auger 4 cuts the larger straw in the material into flakes, the material enters the staggered air duct 2, the first fan 7 starts to blow the chaff and dust in the material upward, the second fan 10 starts the suction force to suck the blown chaff and dust into the negative pressure dust collector 8. The straw and grains continue to move downward because they are heavier, and enter the vibrating screen 6. The vibrating screen 6 starts to screen the grains and flakes of straw through the sieve holes, and finally the screened grains and flakes of straw are poured out from the discharge port of the vibrating screen 6. On the other hand, when the bran and dust enter the negative pressure dust collector 8, the smaller particles of dust will be directly sucked into the top of the negative pressure dust collector 8, and enter the second fan 10 for dust removal along the air duct, while the larger particles of dust and bran will be adsorbed by the filter bags of the negative pressure dust collector 8. When the filter bags accumulate to a certain level, the negative pressure dust collector 8 releases the pressure downward, and the bran and large particles of dust on the surface of the filter bags are driven into the dust removal port. The material is sucked into the brake dragon 9 along the dust removal port pipe. The brake dragon 9 operates to screen the bran and large particles of dust, and the large particles of dust enter the fan dust removal from the dust exhaust pipe of the brake dragon 9, and the screened bran is poured out from the discharge port of the brake dragon 9.

[0043] It is worth noting that the "drive motor, fan, negative pressure dust collector, brake dragon" mentioned in the utility model are all existing technical products with mature process technology. Therefore, their specific working principles will not be elaborated here.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
