[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] Embodiment 1:

[0021] like Figure 1-3As shown, the present embodiment provides a fertilizer rotary screen vibrating device, including a screen plate 100 and a vibrating assembly 200, the screen plate 100 includes a frame 101 at the bottom and a screen 102 at the top, the vibrating assembly 200 includes a plurality of partition frames 201 arranged in the frame 101, and a fixed seat 202 fixedly installed at the center of the inner wall of the four sides of the partition frame 201, and the left and right fixed seats 202 in the partition frame 201 are also movably installed with a first movable rod 203 and a second movable rod 204, and the inner ends of the first movable rod 203 and the second movable rod 204 are also fixedly installed with a first striking rod 205 and a second striking rod 206, respectively, and the first movable rod 203 and the second movable rod 204 are fixedly installed with a first striking rod 206. A spring 207 is also movably installed at the bottom of the movable rod 204. The first striking rod 205 and the second striking rod 206 are both arc-shaped structures. The rapping assembly 200 also includes an inner striking rod 208 fixedly installed on both sides of the first striking rod 205 and the second striking rod 206. The rapping assembly 200 also includes a bottom fixing frame 209 fixedly installed at the bottom of the partition frame 201, and a fixing plate 210 fixedly installed on the bottom fixing frame 209. The bottom of the spring 207 is fixed to the upper end of the fixing plate 210. The rapping assembly 200 also includes a striking seat 211 fixedly installed at the bottom of the first movable rod 203 and the second movable rod 204, and the striking seat 211 is located on the upper part of the spring 207.

[0022] Specifically, the fertilizer rotary screen is a device specially used for fertilizer screening. The fertilizer rotary screen vibrating device is mainly installed in the screen plate 100 in the rotary screen, and is a device for vibrating the screen 102 on the top of the screen plate 100 during screening, thereby avoiding the problem of blockage and accumulation at the upper end of the screen 102. The first movable rod 203 and the second movable rod 204 symmetrically installed at the four sides of the partition frame 201 in the screen plate 100 can be realized through a fixed seat 202 movably connected on one side and a spring 207 movably installed at the bottom, so that when the screen plate 100 vibrates, it follows the vibration of the screen plate 100 and squeezes the spring 207 at the bottom, and then through the first striking rod 205 and the second striking rod 205 that pop up at the upper end. Rod 206 realizes the vibration of the top screen 102, thereby avoiding the problem of fertilizer clogging and accumulation at the upper end of the screen 102. At the same time, the symmetrically arranged annular first striking rod 205 and the second striking rod 206, as well as the inner striking rod 208 fixedly installed on both sides of the inner ends of the first striking rod 205 and the second striking rod 206, can also improve the high range and uniformity of the vibration of the upper end screen 102 of the partition frame 201, thereby ensuring a good vibration effect during use. The striking seat 211 fixedly installed at the bottom of the first movable rod 203 and the second movable rod 204 is mainly used for the first movable rod 203 and the second movable rod 204 to squeeze the bottom spring 207 when the first movable rod 203 and the second movable rod 204 vibrate following the screen plate 100.

[0023] The working principle and use process of this utility model:

[0024] When the screen plate 100 vibrates following the rotary screen during use, the first movable rod 203 and the second movable rod 204 movably installed at the four sides of the partition frame 201 in the screen plate 100 will move up and down around the fixed seat 202, and squeeze the bottom spring 207 through the bottom striking seat 211, and then lift the first striking rod 205 and the second striking rod 206 at the upper end of the striking seat 211 through the elastic force of the spring 207 on the striking seat 211, and then the top screen 102 is vibrated by the first striking rod 205, the second striking rod 206 and the inner striking rod 208 to deal with the accumulation and blockage on the upper end of the screen 102. At the same time, the first striking rod 205, the second striking rod 206 and the inner striking rod 208 evenly arranged in the partition frame 201 can also ensure the uniformity of the vibration of the top screen 102, thereby ensuring a good vibration effect.
