[0023] Please continue reading Figure 1 and Figure 2 As shown, the cleaning device of the utility model is also provided with a dust removal device, a vibrator 30 and a screening device, wherein the dust removal device is provided with an air suction pipe 41, an air suction pump 42, a ventilation pipe 43 and a storage cavity 44, a plurality of clamps 441 are provided on the periphery of the storage cavity 44, the storage cavity 44 is movably clamped in the top frame 21 by the clamps 441, the air suction pump 42 is fixed in the positioning ring 22, one end of the ventilation pipe 43 is connected with the air suction pump 42, and the other end is connected with the storage cavity 44, a plurality of air holes are provided on the storage cavity 44, the screening device is provided with a screening box 51 and a baffle 52 and a sieve plate 53 located in the screening box 51, the baffle 52 is located above the sieve plate 53, the vibrator 30 is fixed at the bottom of the screening box 51, the upper end of the vibration rod 17 is fixed to the bottom of the screening box 51 by bolts, and the connecting plate 14 is connected to the side of the screening box 51 by bolts 60.

[0024] Please refer to Figure 1 As shown, an air outlet (not shown in the figure) is provided on the top of the screening box 51, and the air outlet is connected to the suction pipe 41. A feed port 511 is provided on the side of the screening box 51. In addition, the number of sieve plates 53 can be two, and the two sieve plates 53 are parallel and spaced apart and arranged horizontally in the screening box 51, and are both located below the baffle 52. In addition, a discharge port and a debris removal port (not shown in the figure) are respectively provided on the bottom side of the screening box 51.

[0025] The working principle of the corn seed wind screening cleaning device of the utility model is as follows: the installed cleaning device is placed on a horizontal surface, and after the vibrator 30 is started, the output end of the vibrator 30 is connected to the screening box 51, which then drives the screening box 51 to start vibrating. During the vibration process, since the compression spring 13 and the vibration rod 17 are provided at the bottom of the screening box 51, the screening box 51 will not tip over during the repeated vibration. On the one hand, the compression spring 13 provides a buffering force, and on the other hand, the vibration rod 17 is axially connected to the shaft connecting rod 16, so that the vibration force on the screening box 51 is transmitted to the positioning block 15 and the bottom plate 12 through the vibration rod 17 and the shaft connecting rod 16. Since the bottom plate 12 is located on a plane, the stability of the entire equipment is improved. Yes; after the screening box 51 vibrates, corn seeds can be put into the screening box 51 from the feed port 511, and the transported corn seeds first fall onto the baffle 52 in the screening box 51. The baffle 52 is a plate structure without sieve holes. Under the action of the vibrator 30, the baffle 52 spreads the corn seeds, and then the suction pump 42 is started. The suction pump 42 draws the air in the screening box 51 through the suction pipe 41, and lighter impurities, such as light straw, corn silk and other materials are sucked away and finally enter the storage cavity 44 through the ventilation pipe 43. Since the storage cavity 44 is flexibly placed in the top frame 21, when it is necessary to clean the impurities in the storage cavity 44, the storage cavity 44 and the ventilation pipe 43 can be directly removed, which is convenient to operate and clean.

[0026] Next, after the light impurities in the corn seeds on the baffle 52 are gradually sucked away, they fall onto the sieve plate 53 under the baffle 52. It should be noted here that in a preferred embodiment, the baffle 52 is arranged in a manner of being higher on the left and lower on the right, and the sieve plate 53 located under the baffle 52 is arranged in a manner of being higher on the right and lower on the left, so that the impurities will fall from the lower end of the baffle 52 to the higher end of the sieve plate 53, thereby realizing the vibration screening and cleaning function of the sieve plate 53 on the corn seeds. During the operation of the sieve plate 53, the baffle 52 above it can pre-treat the next round of corn seeds by wind screening, thereby achieving the purpose of simultaneous wind screening cleaning and vibration screen cleaning.

[0027] Through the above technical scheme, the corn seed wind screening cleaning device of the utility model is provided with a dust removal device and a screening device. By arranging a baffle 52 in the upper layer of the screening box 51 of the screening device, the corn seeds on the baffle 52 can be blown to remove impurities while the seeds below the baffle 52 that have completed dust removal are vibrated to remove impurities. The two do not affect each other, thereby improving the impurity removal efficiency of the overall device.

[0028] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
