DETAILED DESCRIPTION

[0022] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 3 , in order to solve the problem of improving wheat screening efficiency.

[0025] The sieve box 13 is tilted and provided with a plurality of filter holes. The push plate 11 is slidably connected in the sieve box 13. A plurality of convex strips 101 are fixedly connected in front of the push plate 11. Two blocking nets are provided on the push plate 11. Two fans 102 are rotatably connected behind the two blocking nets respectively. An arc-shaped bin 12 is welded in front of the push plate 11. A slag discharge port 201 is provided on the arc-shaped bin 12. A fan is provided outside the sieve box 13, and the fan and the slag discharge port 201 are connected by a hose.

[0026] After wheat is harvested, it generally contains lighter impurities such as wheat straw and heavier impurities such as stones. When the present invention is working, the harvested wheat is first placed in the sieve box 13 from the higher side, and the sieve box 13 is slightly tilted, so that the wheat is unevenly distributed in the sieve box 13, and then the sieve box 13 is vibrated, so that the heavier stones will sink, and then be filtered from the sieve box 13 and separated from the wheat. While vibrating the sieve box 13, the push plate 11 is driven to move back and forth in the sieve box 13, thereby driving the arc bin 12 to move back and forth. At this time, the wheat in the sieve box 13 The wheat is pushed upward by the push plate 11, slides along the push plate 11, and then falls back onto the screen box 13 through the arc bin 12, thereby stirring the wheat inside the screen box 13 for easy screening. The push plate 11 moves while the fan 102 rotates, thereby blowing the lighter impurities in the wheat on the push plate 11 to make them float above the wheat, and then the lighter impurities are extracted from the slag discharge port 201 by the fan. The convex strips 101 arranged on the push plate 11 can prevent the wheat from moving on the push plate 11 as a whole, thereby avoiding insufficient filtering of lighter impurities.

[0027] like Figure 3 , to solve the problem of fan 102 rotating.

[0028] A first bevel gear 103 is fixedly connected to the rotating shaft of each fan 102 . The rotating shaft 105 is rotatably connected to the rear of the push plate 11 . Each first bevel gear 103 is meshed with a corresponding second bevel gear 104 . The two second bevel gears 104 are welded to the rotating shaft 105 .

[0029] When the push plate 11 moves, the driving shaft 105 rotates, thereby driving the two second bevel gears 104 to rotate, thereby driving the two first bevel gears 103 that are respectively meshed and driven to rotate, thereby driving the two fans 102 to rotate.

[0030] like Figure 4 , in order to solve the problem of rotation of shaft 105.

[0031] The gear 106 is key-connected to one end of the rotating shaft 105 , the rack 301 is welded to the inner wall of the screen box 13 , and the gear 106 is meshed with the rack 301 .

[0032] The push plate 11 is in a moving state, thereby driving the rotating shaft 105 to move synchronously during the movement, thereby driving the gear 106 to be displaced relative to the rack 301, and then the gear 106 is driven to rotate by meshing, thereby driving the rotating shaft 105 to rotate, and then driving the two fans 102 to work, avoiding the cumbersome circuit or automatic control when a separate motor is set to drive the fan 102 to work.

[0033] like Figure 4 and Figure 5 , in order to solve the problem that wheat accumulates on the rack 301 and affects the rotation of the fan 102.

[0034] The anti-blocking box 202 is welded on the push plate 11 , and a plurality of cleaning strips 203 are slidably connected in the anti-blocking box 202 . A return spring is fixedly connected between each cleaning strip 203 and the anti-blocking box 202 .

[0035] When wheat is screened, due to the vibration of the screen box 13 and the reciprocating movement of the push plate 11, the wheat is easy to fall on the rack 301, which is easy to jam the gear 106 and affect the operation of the equipment. Therefore, an anti-blocking box 202 is arranged to move synchronously with the push plate 11, and the cleaning strip 203 is lifted up when it contacts the protrusion on the rack 301. At this time, the reset spring is compressed, and then as the cleaning strip 203 moves, the reset spring pushes it to press down on the recessed part of the rack 301, so that the wheat fallen therein can be squeezed out to prevent it from getting stuck on the rack 301 and affecting the rotation of the gear 106.

[0036] like Figure 6 , to solve the problem of screen 13 vibration.

[0037] A bracket 14 is disposed outside the sieve box 13 , and a plurality of sliders 401 are slidably connected to the bracket 14 . A first compression spring 402 is fixedly connected between each slider 401 and the sieve box 13 .

[0038] The sieve box 13 is tilted, and the two sliders 401 on each side are respectively located on the upper and lower sides of the sieve box 13, so that when the sieve box 13 is filled with wheat, as the push plate 11 moves, the wheat in the sieve box 13 is pushed to move back and forth, so that the center of gravity of the sieve box 13 as a whole is always in a moving state. The sieve box 13 and the bracket 14 are connected to the first compression spring 402 through multiple sliders 401, and when the center of gravity of the sieve box 13 changes, it slides up and down relative to the slider 401, so that the sieve box 13 vibrates up and down.

[0039] like Figure 7 , in order to further increase the vibration effect of the screen box 13.

[0040] Two clamping plates 405 are slidably connected to the bracket 14, and the screen box 13 is slidably connected between the two clamping plates 405. A second compression spring 406 is fixedly connected between one of the clamping plates 405 and the bracket 14. A driving shaft 403 is rotatably connected to the bracket 14, and a cam 404 is fixedly connected to the driving shaft 403. The cam 404 is in contact with the other clamping plate 405.

[0041] The motor is arranged on the bracket 14, and the output shaft of the motor is connected to the driving shaft 403. The driving motor drives the driving shaft 403 to rotate, and then drives the cam 404 to rotate, and then drives another clamping plate 405 to move, and then pushes the screen box 13 to move, and then drives a clamping plate 405 to move. At this time, the second compression spring 406 is compressed, and as the cam 404 rotates, the other clamping plate 405 is no longer pushed, and then the compressed second compression spring 406 pushes one clamping plate 405 to reset, and similarly, the other clamping plate 405 is reset, and then as the driving shaft 403 rotates, the two clamping plates 405 drive the screen box 13 to move back and forth left and right, thereby increasing the vibration effect on the screen box 13.

[0042] like Figure 8 , to solve the problem of adding wheat.

[0043] The fixing rod 407 is welded between the two clamping plates 405 , and the feeding port 408 is welded on the fixing rod 407 and is located on the higher side of the screen box 13 .

[0044] When wheat is added, it is added from the feed port 408, so that the wheat falls to the higher side of the screen box 13, and slides down along the slightly inclined screen box 13, so that the wheat can be screened during the activity.

[0045] like Figure 8 , to solve the problem of push plate 11 moving.

[0046] Two hydraulic rods 15 are fixedly connected to the other clamping plate 405 . The movable ends of the two hydraulic rods 15 are welded to one side of the cross bar 409 . A push rod 410 is slidably connected to the cross bar 409 . The push rod 410 is welded to the arc-shaped bin 12 .

[0047] The hydraulic rod 15 is driven to move, thereby driving the cross bar 409 to move, thereby driving the push rod 410 to move to the left, thereby driving the arc bin 12 and the push plate 11 to move to the left synchronously. Since the arc bin 12 gradually moves upward, it drives the push rod 410 to move during the movement of the cross bar 409, and the sliding connection between the two will not get stuck.

[0048] like Figure 8 , to solve the problem of pushing plate 11 to reset.

[0049] The screen box 13 is fixedly connected with a slide rail 302 , and the push plate 11 is slidably connected to the slide rail 302 , and a third compression spring is fixedly connected therebetween.

[0050] When the push rod 410 extends, it drives the push plate 11 to move to the left. Similarly, when the push rod 410 contracts, it drives the push plate 11 to move to the right. However, if the push rod 410 contracts too slowly, the wheat will be supported by the push plate 11 and slowly move down along the screen box 13, which will affect the screening effect of the wheat. At this time, a slide rail 302 is set to make the push plate 11 slidably connected to the slide rail 302. When the push rod 410 extends and drives the push plate 11 to move to the left, the third compression spring is compressed, which in turn drives the push rod 410 to contract. The compressed third compression spring is released, which makes the push plate 11 retract quickly, so that the wheat can slowly slide down along the screen box 13.

[0051] like Fig. 9 , a processing method used in a flour processing device, comprising the following steps;

[0052] S1: Put the harvested wheat into the feed port 408 and let it slide down slowly along the screen 13;

[0053] S2: Control the driving shaft 403 to rotate and drive the hydraulic rod 15 to reciprocate and contract, thereby accelerating the wheat screening process and screening out lighter impurities;

[0054] S3: taking the sieved wheat out of the sieve box 13 and then grinding it into powder;

[0055] S4: The ground wheat is sieved to remove larger particles to form finished rice.
