[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-6 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0024] like Figure 1-6 As shown: the present embodiment provides a separation device of a wheat sheller, comprising a separation frame 100, a plurality of support frames 101 arranged in an upper and lower array are fixedly connected to the middle of the separation frame 100, a plurality of connecting seats are arranged on the top of the support frame 101, a bracket 102 is rotatably connected to the middle of the connecting seat, the top of the bracket 102 located on the same support frame 101 is rotatably connected to the same screening frame 103 through the connecting seat, a plurality of sieve openings arranged in an array are provided in the middle of the screening frame 103, the sieve openings of the screening frame 103 are successively smaller from top to bottom, one end of the screening frame 103 is fixedly connected to a guide plate 104, the guide plate 104 is tilted, the screening frame 103 and both sides of the guide plate 104 are fixedly connected to a partition plate 112, and the side of the screening frame 103 close to the guide frame 108 is fixedly connected to a cross plate 113;
[0025] During operation, the uppermost screening frame 103 is driven to move up and down, shaking and screening the wheat, and the wheat and broken grains are screened layer by layer through the screen opening and fall into the next layer of the screening frame 103, while the wheat husks and wheat straw are left on the screening frame 103 and guided out of the separation device through the guide plate 104 as the screening frame 103 moves. The guide plate 104 has no screen opening to prevent impurities in the upper layer from falling into the lower layer. When the upper screening frame 103 moves up and down, it is restricted by the bracket 102, so that when the screening frame 103 moves downward, it is guided by the bracket 102 and moves horizontally at the same time, thereby improving the screening efficiency. The screening ability of the sub-rack 103 can also enable the impurities remaining on the screening rack 103 to be more flexibly moved to the guide plate 104 area for unloading. When the top-level screening rack 103 moves, the connecting rod 105 can drive the lower screening rack 103 to move synchronously. The design of the connecting rod 105 can make the screening rack 103 more flexible when it moves horizontally and will not be restricted by the connecting parts, so that the screening effect of each screening rack 103 is guaranteed. The partition 112 and the cross plate 113 can prevent wheat from overflowing to the lower screening plate or overflowing the working area during screening.
[0026] Telescopic column 107 Figure 1 , 3 As shown,
[0027] The screening frames 103 are rotatably connected with connecting rods 105 through connecting seats, the top center of the separation frame 100 is fixedly connected with a support 106, the bottom center of the support 106 is fixedly connected with a telescopic column 107, and the telescopic end of the telescopic column 107 is provided with a magnetic plate, which fits with the top center of the screening frame 103;
[0028] In actual operation, by controlling the extension and retraction of the telescopic column 107, the attraction between the magnetic plate and the top of the screening frame 103 can be easily achieved. As the telescopic column 107 is extended and retracted, the screening frame 103 will move up and down accordingly, thereby achieving the vibration of the screening frame 103 and realizing the screening of wheat.
[0029] Guide frame 108 Figure 2 , 3 , 5, and 6,
[0030] A guide frame 108 is fixedly connected to one side of the separation frame 100, and a plurality of top columns 109 arranged in an array are slidably connected to the middle part of the guide frame 108. A limit plate 110 is provided at one end of the top column 109 away from the screening frame 103. A spring 111 is sleeved on the outer side of the top column 109 between the limit plate 110 and the guide frame 108. A plurality of pads 114 are connected to one side of the cross plate 113 close to the guide frame 108 by bolts. One end of two adjacent top columns 109 is fixedly connected to the same top plate 115. The positions of the pads 114 correspond to the positions of the adjacent top plates 115, and the height of the top plates 115 is greater than the height of the pads 114.
[0031] When the screening frame 103 moves upward, the cross plate 113 will approach the guide frame 108, so that the pad 114 fits with the adjacent top plate 115, and then the top column 109 is away from the cross plate 113, so that the spring 111 is stretched and expanded. When the screening plate is lifted to the limit, the spring 111 is pulled to the maximum. At this time, the contraction force of the spring 111 is greater than the suction force of the magnetic plate. The contraction of the spring 111 will cause the top column 109 to move toward the cross plate 113, pushing the cross plate 113 and the screening frame 103 to move. The moving direction of the screening frame 103 is guided to the principle guide frame 1 The side of 08 is also the side close to the guide plate 104. At the same time, the impact force provided by the spring 111 will make the screening frame 103 get additional power, make the vibration amplitude larger, and improve its screening effect. The pad 114 protects the cross plate 113 from damage. The pad 114 is easily damaged by the impact of the top plate 115 for a long time. It can be easily maintained and replaced by bolts. At the same time, the top plate 115 is larger than the pad 114, which can ensure that the pad 114 can still dock with the top plate 115 when the height of the pad 114 changes, and bear the impact force transmitted by the spring 111.
[0032] Working principle:
[0033] First, the wheat is fed into the top screening rack. During the screening process, the wheat and broken grains fall through the sieve opening into the next screening rack, while the husks and straw are left on the top screening rack. As the screening rack moves, these impurities are guided out of the separation device through the guide plate. The design of the guide plate prevents upper impurities from falling into the lower layer, ensuring the separation effect. While the screening frame moves up and down, the bracket limits its moving path, causing the screening frame to move laterally when moving downward. At the same time, the impurities remaining on the screening frame can be more flexibly moved to the guide plate area for unloading. The movement of the top screening frame drives the lower screening frame to move synchronously through the connecting rod. The design of the connecting rod makes the screening frame more flexible when moving laterally, thereby ensuring the screening effect of each screening frame. The attraction between the magnetic plate and the top of the screening frame realizes the vibration of the screening frame by controlling the extension and contraction of the telescopic column. When the screening frame moves up and approaches the guide frame, the pad is fitted with the top plate and the spring is stretched. When the screening frame is lifted to the limit, the contraction force of the spring causes the top column to move toward the cross plate, pushing the cross plate and the screening frame to move, providing additional power and a larger vibration amplitude, thereby improving the screening effect.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0035] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
