DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A vibration powder screening device dedicated to inoculant includes a base 1, on which vibrators 2 are symmetrically fixedly installed, and a screen box 3 is fixedly installed between the two vibrators 2. The vibrator 2 can drive the screen box 3 to move horizontally back and forth (the vibrator 2 is a prior art and will not be introduced in detail here). During screening, the inoculant to be screened is put into the screen box 3, and then the screen box 3 is driven by the vibrator 2 to move horizontally back and forth on the base 1. During the movement, the screening of the inoculant is achieved.

[0022] The screen box 3 is symmetrically fixed with mounting blocks 4, and rectangular grooves are provided on the surfaces of the two mounting blocks 4. Vertical rods 5 are installed in the rectangular grooves through lifting components. Cross bars 6 are fixedly installed at the lower ends of the two vertical rods 5, and a rolling block 7 is fixedly installed between the two cross bars 6. Two groups of transmission components for driving the rolling block 7 to move downward are provided in the screen box 3. The lifting component includes a lifting block 8 slidably installed in the rectangular groove and a telescopic spring 9 fixedly installed on the lower surface of the lifting block 8. The end of the telescopic spring 9 away from the lifting block 8 is fixedly connected to the inner wall of the rectangular groove, and the vertical rod 5 is fixedly installed on the lifting block 8.

[0023] The lifting block 8 can move up and down in the rectangular groove. When the lifting block 8 moves downward, the telescopic spring 9 is compressed and drives the vertical rod 5 to move vertically downward, and then drives multiple rolling blocks 7 to move vertically downward through the cross rod 6.

[0024] The transmission assembly includes a U-shaped rod 10 fixedly mounted on the base 1, two trapezoidal blocks 11 symmetrically fixedly mounted on the U-shaped rod 10, a rectangular plate 12 fixedly mounted on the rolling block 7, and a top rod 13 fixedly mounted on the rectangular plate 12. Moving holes are symmetrically opened on both side surfaces of the screen box 3, the U-shaped rod 10 is slidably inserted into the moving holes, and the top end of the top rod 13 is in sliding contact with the inclined surfaces of the two trapezoidal blocks 11.

[0025] When the screen box 3 moves horizontally, it will drive multiple rolling blocks 7, rectangular plates 12 and top rods 13 in the screen box 3 to move together, and the U-shaped rod 10 is fixedly installed on the base 1. When the top rod 13 moves, it will slide in contact with the inclined surface of the trapezoidal block 11. The inclined surface of the trapezoidal block 11 will exert a downward force on the top rod 13, thereby driving the rectangular plate 12 to move vertically downward through the top rod 13, and then driving multiple rolling blocks 7 to move vertically downward through the rectangular plate 12, contacting and squeezing the condensed inoculant in the screen box 3, thereby crushing the condensed inoculant into powder, without the need for separate processing at a later stage, reducing the work intensity of the staff and effectively improving the practicability of the device.

[0026] A rotating groove is provided at the top of the push rod 13, and a roller 14 is rotatably installed in the rotating groove. The roller 14 is in rolling contact with the inclined surface of the trapezoidal block 11. When the top of the push rod 13 moves on the inclined surface of the trapezoidal block 11, the roller 14 will contact the inclined surface of the trapezoidal block 11 and rotate relatively. The roller 14 can reduce the friction between the push rod 13 and the trapezoidal block 11.

[0027] A collecting box 15 is fixedly mounted on the lower surface of the screen box 3. A rectangular groove is provided on the side of the collecting box 15. A collecting box 16 is slidably inserted into the rectangular groove. The screened inoculant will fall into the collecting box 16 to collect the inoculant.

[0028] A plurality of ejectors are fixedly mounted on the lower surface of the rolling block 7, and the number of the ejectors is no less than ten. When the rolling block 7 contacts the agglomerated inoculant, the ejectors are inserted into the inoculant, thereby facilitating the crushing of the inoculant.

[0029] In the utility model, during the horizontal movement of the screen box 3, the multiple rolling blocks 7 in the screen box 3 will be driven to move together, and the U-shaped rod 10 is fixedly installed on the base 1. Through the cooperation of the transmission component and the lifting component, the multiple rolling blocks 7 can be driven to move vertically downward, contact with the agglomerated inoculant in the screen box 3, and squeeze it, thereby crushing the agglomerated inoculant into powder, without the need for subsequent separate processing, reducing the work intensity of the staff, and effectively improving the practicability of the device.

[0030] In general, in view of the technical problem: after screening, the staff is required to crush the agglomerated block inoculant separately at a later stage, the processing flow is complicated, the work intensity of the staff is increased, and the practicality is not high; a technical solution is adopted: through the cooperation of the transmission component, the lifting component, the vertical rod 5 and the horizontal rod 6, the rolling block 7 is continuously driven to roll the agglomerated block inoculant in the screen box 3; because the implementation process of the technical solution is: during the horizontal movement of the screen box 3, it will drive the multiple rolling blocks 7 in the screen box 3 to move together, and the U-shaped rod 10 is fixedly installed on the base 1, and through the cooperation of the transmission component and the lifting component, it can drive the multiple rolling blocks 7 to move vertically downward, contact with the agglomerated block inoculant in the screen box 3, and squeeze it, thereby crushing the agglomerated block inoculant into powder; so the technical problem can be solved inevitably, and the technical effect achieved is: no need for separate processing at a later stage, reducing the work intensity of the staff, and effectively improving the practicality of the device.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
