A shaking and swinging drive component 6 is provided on the filter bucket body 1.

[0029] like Figure 3 - Figure 5As shown, the shaking and swinging assembly 5 includes a first spiral spring 51 fixedly connected at the four corners of the bottom end of the inner side of the accommodating groove 2 and a first drive shaft 52 rotatably arranged in the inner side of the accommodating groove 2, one end of the first spiral spring 51 is fixedly connected with the filter screen plate 3, a first protrusion 53 is fixedly arranged on the first drive shaft 52, a partition plate 54 is arranged on one side of each of the two first drive shafts 52, the protective screen plate 4 is arranged on the upper end faces of the two partition plates 54 and the two first drive shafts 52, and a groove is formed in the inner side wall of the accommodating groove 2. A second drive shaft 55 is rotatably arranged in the inner side of the groove, a second protrusion 56 is fixedly arranged on the second drive shaft 55, a push block 57 is arranged on one side of the groove, and an insertion block 58 is fixedly arranged on the side wall opposite to the groove of the push block 57. One end of the insertion block 58 is inserted into the groove, a plurality of second spiral springs 59 are fixedly arranged on the side wall opposite to the groove of the push block 57, and one end of each of the second spiral springs 59 is fixedly connected to the bottom end of the inner side of the groove.

[0030] The setting of the shaking and swinging assembly 5 can drive the filter screen plate 3 to perform up-and-down shaking and left-and-right swinging movements, and the up-and-down shaking and the left-and-right swinging movements are alternated with each other, so as to avoid movement conflict. The up-and-down shaking and the left-and-right swinging movements of the filter screen plate 3 drive the grain placed on the upper end face of the filter screen plate 3 to shake and swing, and the shaking and swinging of the grain make the dust and impurities mixed in the grain be screened to the upper end face of the filter screen plate 3, so as to improve the screening and filtering effect of the filter screen plate 3 on the dust and impurities mixed in the grain in the filter bucket body 1, thereby effectively improving the screening and filtering quality of the grain.

[0031] As shown in Figure 2 Figure 4 The shaking and swinging driving assembly 6 includes a driving motor 61, two first transmission wheels 62 and a second transmission wheel 63. The output end of the driving motor 61 is butted with one end of each of the two first drive shafts 52, the second transmission wheel 63 is butted with one end of the second drive shaft 55, and the second transmission wheel 63 is connected with one of the first transmission wheels 62 through a belt.

[0032] The setting of the shaking and swinging driving assembly 6 provides kinetic energy for the operation of the shaking and swinging assembly 5.

[0033] A buffer groove 7 is formed in the inner side wall of the accommodating groove 2, the buffer groove 7 is located on one side of the filter screen plate 3, and a dust discharging port 8 is formed in the inner side wall of the buffer groove 7. The buffer groove 7 provides swinging space for the left-and-right swinging of the filter screen plate 3, and the dust discharging port 8 can discharge the dust and impurities in the buffer groove 7 out of the filter bucket body 1.

[0034] ​The working principle of this practical application is as follows:

[0035] First, shovel the grain to the bottom inner side of the filter basket body 1, or directly place the grain into the bottom inner side of the filter basket body 1. The grain at the bottom inner side of the filter basket body 1 will be on the upper surface of the filter screen plate 3. At this time, start the drive motor 61. The drive motor 61 drives the first drive shaft 52 connected to it to rotate. The first drive shaft 52 drives the first transmission wheel 62 connected to it to rotate. The first transmission wheel 62 drives another first transmission wheel 62 to rotate via a belt. The rotation of the two first transmission wheels 62 drives the first transmission wheel 62 connected to it to rotate. During the rotation of the first transmission wheel 62, the second transmission wheel 63 is driven to rotate via a belt. The rotation of the second transmission wheel 63 drives the second drive shaft 55 to rotate. When the first protrusion 53 on the first transmission wheel 62 contacts the filter screen plate 3, the first protrusion 53 pushes the filter screen plate 3 upward. During the upward movement of filter screen 3, the first helical spring 51 deforms under force and is stretched. When the first protrusion 53 on the first transmission wheel 62 is misaligned with the filter screen 3, the filter screen 3 receives pressure from the grain on its upper surface and downward pulling force from the first helical spring 51, causing the filter screen 3 to return to its original position. At this time, the second protrusion 56 on the second drive shaft 55 will push against the insert 58 on the push block 57. The insert 58 is pushed by force to move the push block 57 toward the filter screen 3, and the filter screen 3 is moved toward the buffer groove 7. During the movement of the filter screen 3, the second helical spring 59 deforms under force and is stretched. When the second protrusion 56 on the second drive shaft 55 is misaligned with the insert 58, the push block 57 returns to its original position under the pull of the second helical spring 59. By repeating this process, the filter screen 3 can achieve the alternating motion of shaking up and down and swinging left and right.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
