Technical Field

[0001] The utility model relates to the technical field related to grain screening machines, and in particular to a high-efficiency grain screening machine for smart agriculture. Background Art

[0002] Grain screening machine is a kind of equipment used to screen, grade and clean grains. Its main function is to remove impurities, foreign matter and unqualified particles in grains through screening, vibration or airflow to improve the quality and purity of grains. Olive is also a kind of grain. Now we design an efficient smart agricultural grain screening machine to remove impurities from olives.

[0003] According to Chinese patent: CN218013909U, a grain screening device for smart agriculture includes: a screening box, a box door is hinged on the outside of the screening box, screening mechanisms are arranged on the top and inside of the screening box, a cleaning mechanism is arranged on one side of the screening mechanism, a collecting hopper is fixedly connected to the inner wall of the screening box, a feed hopper is fixedly connected to the top of the screening box, the screening mechanism includes a protective box, the protective box is fixedly connected to the top of the screening box, a motor is fixedly connected to the inner wall of the protective box, a rotating shaft is fixedly connected to the right side of the motor, and an active bevel gear is fixedly connected to the right end of the rotating shaft.

[0004] Based on the above patents and in combination with the prior art, it is found that:

[0005] 1. The device in the above-mentioned document separates the grain from the impurities by stirring the grain, but the contact area between the push block used in the device and the grain is small, so that the collision and friction between the grains are small, thereby reducing the efficiency and effect of separating the impurities;

[0006] 2. In some stirring and screening machines currently on the market, grains will mix and collide during the stirring process, and some fine impurities may not be completely separated, or may pass through the screen together with the grains. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-efficiency smart agricultural grain screening machine.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] An efficient smart agricultural grain screening machine, comprising:

[0010] The outer cylinder is the external structure of the device, and a No. 1 motor is fixedly installed on the top;

[0011] The bottom of the first motor is connected to a transmission shaft, and the end of the transmission shaft is fixedly connected to a transmission block;

[0012] The side of the transmission block is fixedly connected to four push plates, and the top of the push plates is fixedly connected to a baffle;

[0013] An upper sieve plate and a lower sieve plate are arranged below the transmission block, a driving wheel is arranged on the side of the lower sieve plate, and the driving wheel is transmission-connected to the second motor above;

[0017] Preferably, a transmission box is fixedly connected to the side of the outer cylinder, and a second motor is fixedly installed above the transmission box;

[0018] A driving wheel is movably installed in the transmission box.

[0019] Preferably, the outer wall of the lower sieve plate is provided with teeth, and the lower sieve plate is meshed with the driving wheel through the teeth.

[0020] Preferably, a discharge port is provided at the bottom of the outer cylinder;

[0021] The supporting legs are fixedly connected to the bottom of the outer cylinder.

[0022] Preferably, an intelligent control panel is fixedly mounted on the outer wall of the outer cylinder, and the intelligent control panel can set parameters and control the No. 1 motor and the No. 2 motor through the parameters.

[0023] Preferably, a feeding hopper is fixedly connected to the top of the outer cylinder.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] (1) Start the No. 1 motor to drive the transmission shaft and the transmission block, and drive the push plates and baffles to rotate clockwise on the upper sieve plate. By setting the push plates with a certain slope and the baffles with a certain height, the contact area between the stirring structure and the grain is increased, and the collision and friction degree of the grain during stirring is increased, thereby improving the stirring efficiency and quality of the stirring structure.

[0026] (2) When the impurities and grains are separated, the second motor is started to rotate the driving wheel and drive the lower sieve plate. The sieve holes on the upper sieve plate and the lower sieve plate move relative to each other to open a channel for the grains to fall. The grains then fall on the guide rods in the bottom box and are then sent out of the bottom box by the inclined guide rods. By setting up a number of inclined guide rods, the grains fall and hit the guide rods, and when the grains roll, the impurities on the grains can be further shaken off.

[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0036] Example: Figure 1As shown, a high-efficiency smart agricultural grain screening machine includes: an outer cylinder 1, which is the external structure of the device, with a No. 1 motor 7 and a feeding hopper 3 fixedly installed on the top, the former can provide power for the screening function of the device, and the latter can put olives into the device, the side wall of the outer cylinder 1 is fixedly connected with a transmission box 5, and a No. 2 motor 6 is fixedly installed on the top, and the No. 2 motor 6 can provide power for the transmission structure in the transmission box 5, and an intelligent control board 2 is fixedly installed on the outer wall of the outer cylinder 1, which can intelligently control the No. 1 motor 7 and the No. 2 motor 6 through set parameters, and the bottom of the outer cylinder 1 is fixedly connected to a bottom box 18, and the bottom box 18 can further separate the olives and impurities, and a plurality of support legs 4 are fixedly connected to the bottom of the bottom box 18 for supporting the outer cylinder 1.

[0037] like Figure 2-4 As shown, it includes: a No. 1 motor 7, a transmission shaft 8 connected to the bottom for transmission, a transmission block 11 fixedly connected to the end of the transmission shaft 8, four push plates 10 fixedly connected to the outside of the transmission block 11, the push plates 10 have a certain inclination angle, and the top of the push plates 10 is fixedly connected to the baffle 9. After starting the No. 1 motor 7, the push plates 10 and the baffle 9 can be rotated clockwise through the transmission shaft 8 and the transmission block 11. The push plates 10 with inclined surfaces and the baffles 9 with a certain height increase the contact area with the grain, which can provide a more efficient stirring effect. An upper sieve plate 15 is arranged below the transmission block 11, which is fixedly connected to the inner wall of the outer cylinder 1. At the same time, the transmission block 11 is movably installed above the upper sieve plate 15 through a rotating shaft, and a lower sieve plate 14 is movably installed below the upper sieve plate 15 through a mounting hole 16. The thickness of the upper sieve plate 15 is much smaller than that of the lower sieve plate 14. The outer wall of the lower sieve plate 14 is provided with tooth patterns and meshes with the driving wheel 13 in the transmission box 5. The driving wheel 13 is connected to the No. 2 motor 6 above, and the driving wheel 13 can be rotated by the No. 2 motor 6. Then, the lower sieve plate 14 is rotated below the upper sieve plate 15 through transmission. Sieve holes 17 of the same size are provided at the same position of the upper sieve plate 15 and the lower sieve plate 14, which can be used to filter impurities on the sieved olives.

[0038] like Figure 5 As shown, it includes: guide rods 19, which are arranged at a certain angle and connected to the bottom box 18, and the distance between every two guide rods 19 is less than the minimum width of the olives, which can make the olives falling from above be guided out from the side of the bottom box 18. A discharge port 12 is provided at the bottom of the bottom box 18 to discharge impurities falling from above.

[0039] The device realizes and improves the intelligence of the device by setting up and utilizing sensors, data analysis and algorithms, automatic control systems, human-machine interfaces and remote monitoring.

[0040] Working principle: Under normal conditions, the sieve holes 17 of the upper sieve plate 15 and the lower sieve plate 14 are misaligned with each other, and the grain will not pass through the sieve holes 17. After setting the parameters through the intelligent control panel 2, the grain is poured from the hopper 3 into the outer cylinder 1, and then the No. 1 motor 7 is started to drive the transmission shaft 8 and the transmission block 11, and drive each push plate 10 and the baffle 9 to rotate clockwise on the upper sieve plate 15. By setting the push plate 10 with a certain slope and the baffle 9 with a certain height, the contact area between the stirring structure and the grain is increased, and the collision and friction degree of the grain during stirring is increased, thereby improving the stirring efficiency and quality of the stirring structure. Impurities will fall into the bottom box 18 through the gaps formed by the sieve holes 17, and finally be sent out of the device from the discharge port 12. When the impurities are separated from the grain, the No. 2 motor 6 is started to rotate the driving wheel 13 and drive the lower sieve plate 14. The channel for the grain to fall is opened through the relative movement of the sieve holes 17 on the upper sieve plate 15 and the lower sieve plate 14. Then the grain falls on the guide rod 19 in the bottom box 18, and then the grain is sent out of the bottom box 18 through the inclined guide rod 19. By setting a plurality of inclined guide rods 19, the grain falls and hits the guide rod 19, and when the grain rolls, the impurities on the grain can be further shaken off.
