The working principle of the embodiment is as follows: when the grain separator is used, firstly, as shown in figure 2, the mounting rod 9 protruding from the rear side surface of the shell main body 1 is connected with an external servo motor through an external coupler, and then the external servo motor is connected with an external power supply, at this time, the external servo motor starts to drive the mounting rod 9 to rotate, then as shown in figures 5-6, the mounting rod 9 drives the outside conveying belts 20 to rotate together in the rotating process, so that the screw rod 14 inside one end of the conveying belt 20 outside the mounting rod 9 rotates, and similarly, the screw rod 14 drives the outside conveying belt 20 to rotate in the rotating process, so that the fixing rod 19 inside one end of the other conveying belt 20 rotates, and the screw rod 14 and the fixing rod 19 are driven to rotate together with the fixing rod 19 through 2 conveying belts 20, then, the operator transfers the rough rice into the discharging chamber 11 through external auxiliary equipment, and then, as shown in fig. 1-2, the material inside the discharging chamber 11 is transferred to the distributing cover 15 through the connecting hose 12.
Meanwhile, the screw rod 14 drives the moving block 13 which is in threaded connection with the outer side to move in the rotating process, so that the moving block 13 drives the material distribution cover 15 at the bottom end to perform reciprocating movement above the left end of the placing frame 2, and further the material distribution cover 15 uniformly sprays the grain roughness along the arc-shaped transverse plate 7 above the left end of the first filter plate 3 in the placing frame 2, so that the grain roughness is prevented from being accumulated at one position to influence the movement in the later period of the grain roughness, meanwhile, as shown in figure 1, the mounting rod 9 drives the cam 10 at the outer side to rotate in the rotating process, so that the cam 10 drives the transverse plate 7 to rotate under the action of the inner movable shaft, meanwhile, the transverse plate 7 performs intermittent reciprocating swinging work under the mutual matching of the return spring 8 and the cam 10, and further, a part of materials falling on the transverse plate 7 performs spraying movement under the rotating swinging of the transverse plate 7 in the blanking process of the material distribution cover 15, thereby make the distance of some material whereabouts become far away under the effect of diaphragm 7 is shed to screening work in later stage.
Then, as described above, the grain roughness uniformly falls on the inclined first filter plate 3 inside the placing frame 2, the grain roughness is moved to the right side on the first filter plate 3 and is screened along with the gravity of the grain roughness itself and the inclined first filter plate 3, as shown in fig. 2, when the grain roughness moves to a certain position on the first filter plate 3, a certain thrust is applied to the corresponding partition plate 16, at this time, as shown in fig. 3-4, the corresponding partition plate 16 rotates by a certain angle between 0 to 20 ° under the action of the connecting rod 202 and the fixing block 203, and the corresponding partition plate 16 and the adjacent partition plate 16 also rotate, so that 2 adjacent partition plates 16 do not contact each other, the movement of the grain roughness is not affected, the contact area of the grain roughness and the first filter plate 3 can be increased by the rotation of the partition plate 16, and the screening efficiency is improved, then when the husky and corresponding division board 16 separation of millet, at this moment division board 16 does not receive the husky extrusion force of millet and drives division board 16 through the power of holding of torsion spring 204 and carry out the counter-rotating and reset, at this moment division board 16 can swing the impurity of outside adhesion at rotatory in-process, so that the impurity of adhesion drops and removes, and then avoid impurity to stay on first filter 3, from this the length of the motion trail of husky millet on first filter 3 has not only been prolonged through the mutual cooperation work of a plurality of division boards 16, the quality of screening has been improved, still be convenient for impurity fine along with a plurality of division boards 16 along with the unloading groove 5 fall collect the discharge outside in the room 6 that gathers materials that corresponds.
Then the grains fall into the second filter plate 4 with smaller meshes below through the first filter plate 3 to carry out secondary screening work, and in the same way, the screened grains enter the material collecting chamber 6 along with the material discharging groove 5 corresponding to the right end of the second filter plate 4 to be discharged, so as to be convenient for later collection, then, fine impurities enter the material discharging opening at the bottom end of the shell main body 1 through the opening shape at the bottom of the placing frame 2 and the screening of the second filter plate 4 to be discharged, meanwhile, the fixing rod 19 rotates in the working process of the first filter plate 3 and the second filter plate 4, as shown in figure 6, the conical gear set 21 at the bottom end is driven to rotate in the rotating process of the fixing rod 19, and then the crankshaft connecting rod mechanism 17 inside the conical gear set 21 is rotated, therefore, as shown in figure 2, the crankshaft connecting rod mechanism 17 drives the push rod 18 to move back and forth, and back of the placing frame 2 is driven, place 2 left ends of frame simultaneously and slide in the spout of 1 inner wall of shell main part through the slider, place the spacing inslot that the lower chute 5 of 2 right-hand members of frame slides in 6 through the stopper that gathers materials to in place the stable swing back and forth of frame 2, be convenient for place the fine screening work that carries on of first filter 3 and second filter 4 of 2 inside of frames, above be the use of whole device, thereby accomplish a series of works.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
