Technical Field

[0001] This utility model relates to the field of grain screening technology, and in particular to a grain screening device for smart agriculture. Background Technology

[0002] Grains refer to the general term for various plant seeds used in cooking, and can also be broadly referred to as "cereals". Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch and so on.

[0003] Utility model patent CN218013909U relates to the field of smart agriculture technology and discloses a smart agriculture grain screening device. The device includes a screening box with a hinged door on the outside. Screening mechanisms are installed on the top and inside of the screening box, and a cleaning mechanism is installed on one side of each screening mechanism. A collection hopper is fixedly connected to the inner wall of the screening box, and a feeding hopper is fixedly connected to the top of the screening box.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A smart agricultural grain screening device includes a support frame 1, a U-shaped connecting frame 2 movably mounted on the support frame 1, a plurality of filter plates 3 mounted on the U-shaped connecting frame 2, the plurality of filter plates 3 being arranged vertically inclined from top to bottom in a manner with apertures decreasing from large to small, a dual-axis motor 4 mounted on the support frame 1, an eccentric wheel 5 mounted on each of the two output shafts of the dual-axis motor 4, a connecting rod 6 connected to the eccentric wheel 5, and a transmission shaft 7 connected to the other end of the connecting rod 6, the transmission shaft 7 being fixed to the bottom of the U-shaped connecting frame 2.

[0022] In use, grain particles are fed into the top filter plate 3 from the end closest to the dual-shaft motor 4. The operation of the dual-shaft motor 4 drives the two eccentric wheels 5 to rotate, which in turn drives the connecting rod 6 to move back and forth. The connecting rod 6 then pulls the U-shaped connecting frame 2, causing the filter plate 3 to move back and forth synchronously. This allows the grain particles to move on the filter plate 3, with particles smaller than the aperture of the filter plate 3 falling into the next filter plate 3, while particles larger than the aperture of the filter plate 3 remain on the current filter plate 3. By using several filter plates 3 arranged from top to bottom with progressively smaller apertures, the device can distinguish and screen grain particles of different sizes, thereby achieving fine screening of grain particles and further improving the accuracy of grain screening, meeting the production requirements for fine grain screening.

[0023] Specifically, in this embodiment, the U-shaped connecting frame 2 is provided with several springs 8 on both sides perpendicular to the drive shaft 7. The other end of the several springs 8 is connected to the support frame 1. The arrangement of the springs 8 enables the U-shaped connecting frame 2 to achieve a movable connection with the support frame 1 through the elasticity of the springs 8. This allows the U-shaped connecting frame 2 to be stably connected to the support frame 1 while reciprocating along the horizontal direction, thereby realizing the operation of driving the filter plate 3 to move.

[0024] Specifically, in this embodiment, the inner wall of the U-shaped connecting frame 2 is provided with a number of connecting grooves 9, and the connecting grooves 9 correspond one-to-one with a number of filter plates 3, so that the filter plates 3 can be installed on the U-shaped connecting frame 2 through the corresponding connecting grooves 9, thereby making it convenient for users to replace filter plates 3 of different specifications according to different types of grains, and further improving the flexibility and practicality of the device.

[0025] Specifically, in this embodiment, when the filter plate 3 is embedded in the corresponding connecting groove 9, it can be fixed to the U-shaped connecting frame 2 by bolts. Fixing the filter plate 3 to the U-shaped connecting frame 2 by bolts can improve the connection stability between the filter plate 3 and the U-shaped connecting frame 2, thereby preventing the filter plate 3 from falling off the U-shaped connecting frame 2 during reciprocating movement.

[0026] Specifically, in this embodiment, a feed inlet 10 is provided on the upper side of the U-shaped connecting frame 2 near the dual-axis motor 4. By setting the feed inlet 10, the grain particles can be put into the high part of the filter plate 3. Then, by tilting the filter plate 3 in conjunction with the screening operation, the screened grain particles are transported to the low part of the filter plate 3 so as to facilitate the unified collection of grain.

[0027] Specifically, in this embodiment, a fan 11 and a discharge cylinder 12 are respectively provided on both sides of the U-shaped connecting frame 2. The fan 11, the discharge cylinder 12 and the feed inlet 10 are on the same plane, so that when the feed inlet 10 puts grain onto the filter plate 3, the fan 11 can separate the dust and impurities contained in the grain and blow them into the discharge cylinder 12, and the impurities are discharged uniformly from the discharge cylinder 12.

[0028] Specifically, in this embodiment, a guide plate 13 is provided at the feeding end of several filter plates 3, and several discharge cylinders 14 are provided on the U-shaped connecting frame 2. The inlet position of the discharge cylinder 14 corresponds to the height of the filter plate 3. The guide plate 13 can restrict the grain flow path on each layer of filter plate 3. The restriction of the guide plate 13 allows the grain to enter the discharge cylinder 14 corresponding to that layer of filter plate 3 and be discharged uniformly by the discharge cylinder 14.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
