[0034] Each material-dispensing member 9 has an air cavity Ⅰ9001 therein; all the air cavities Ⅰ9001 are connected to the hollow cavity of the rotating shaft 7; the lower part of each air cavity Ⅰ9001 is connected to a plurality of hollow rubber tubes 9002 with sealed lower ends; the partition plate 10 is in contact with all the hollow rubber tubes 9002.

[0035] It also includes a mounting plate 101, an elastic member 102 and a protective cover 103; the rotating shaft 7 is welded with two mounting plates 101 distributed on the left and right; each mounting plate 101 is fixedly connected with at least three elastic members 102 arranged equidistantly; the elastic member 102 is a spring rod; all the telescopic parts of the elastic members 102 on each mounting plate 101 are fixedly connected with a protective cover 103, and each protective cover 103 is located above a material-pickup member 9.

[0036] It also includes a paddle 104 and a vibration plate 105 ; each protective cover 103 is welded with a deformable paddle 104 on the side away from the rotating shaft 7 ; each paddle member 9 is welded with a vibration plate 105 on the side away from the rotating shaft 7 ; each vibration plate 105 is in contact with a paddle 104 .

[0037] The working steps of the above embodiment are as follows:

[0038] Connect the rotating shaft 7 to the external motor; connect the air pipe 11 to the air pump;

[0039] First, place the receiving hopper 5 on the base 1, and then push the receiving hopper 5 to the bottom of the crushing tube 3, and then fix the receiving hopper 5 and the base 1 together through two pins 6. The raw materials for lithium manganese iron phosphate processing are hereinafter referred to as raw materials. Then, part of the raw materials are poured into the crushing tube 3 through the feeding hopper 4. The raw materials fall on the partition 10. The external motor drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the two rolling rollers 8 and the two material-dispensing members 9 to rotate. The rolling rollers 8 crush the raw materials on the partition 10, and the crushed raw materials remain on the partition 10. Then, the external air pump passes through the air pipe 1 1 injects gas into the hollow cavity of the fixing frame 12, and then the gas enters the hollow rotating shaft 7, and then the gas enters each hollow rubber tube 9002 from the rotating shaft 7 through the two air cavities I 9001, so that each hollow rubber tube 9002 is stretched straight. During the rotation of the material-pickling member 9, the corresponding hollow rubber tube 9002 is also driven to rotate, and the hollow rubber tube 9002 sweeps the crushed raw materials on the partition 10. When the crushed raw materials are swept to the filter hole 1001, the crushed raw materials pass through the filter hole 1001 and fall below the partition 10, and are finally collected in the receiving hopper 5.

[0040] When the rolling roller 8 performs circular motion to crush the raw material, the rolling roller 8 will also drive part of the raw material to transfer on the partition 10. By controlling the rotation shaft 7 to reverse, the external air pump is controlled to stop pumping air into the rotating shaft 7, and part of the gas in the rotating shaft 7 is released, so that the air pressure in the hollow rubber hose 9002 is reduced, so that the hollow rubber hose 9002 is no longer tight. With the reversal of the rotating shaft 7, the material shifting piece 9 also reverses, and synchronously drives the corresponding hollow rubber hose 9002 to rotate. The raw material that is moved by the rolling roller 8 in the circular motion will stagnate in place when the rolling roller 8 reverses, and then the material shifting piece 9 brings the hollow rubber hose 9002 to the stagnant raw material. At this time, the state of the raw material is in the shape of a mound, and the hollow rubber hose 9002 is in a soft state. When the hollow rubber hose 9002 contacts the raw material, it is deformed and bent, and then after the hollow rubber hose 9002 bypasses the raw material, the external air pump re Air is pumped into the rotating shaft 7 again, and the pressure in the rotating shaft 7 increases, so that the hollow rubber hose 9002 is stretched again. Then the rotating shaft 7 is controlled to continue to rotate forward, and the stretched hollow rubber hose 9002 begins to move with the raw materials. During the movement of the raw materials, the crushed raw materials fall down from the filter holes 1001 when they reach the filter holes 1001, while the raw materials with larger particle sizes are still driven by the hollow rubber hose 9002 to continue to move. When the hollow rubber hose 9002 leaves the filter holes 1001 area on the partition 10, the air pump is controlled to stop pumping air and release part of the pressure in the rotating shaft 7, and the hollow rubber hose 9002 is no longer stretched. After the hollow rubber hose 9002 becomes soft, it can no longer drive the raw materials to continue to move. The hollow rubber hose 9002 bends and deforms, and continues to rotate and bypass the raw materials. Then, as the rolling roller 8 makes a circular motion, it rolls and crushes the stagnant raw materials again, and the above process is repeated until all the raw materials are crushed and collected in the receiving hopper 5.

[0041] Considering that the raw material is put onto the partition 10 through the feed hopper 4, when the raw material falls, the raw material hits the protective cover 103, protecting the material-pickup member 9 below, and at the same time, the corresponding elastic member 102 on the protective cover 103 is compressed to buffer the impact of the raw material falling down, and the protective cover 103 also drives the paddle 104 to move downward, and the paddle 104 contacts the vibration plate 105, such as Figure 7 As shown, the vibration plate 105 bends and deforms, and then the paddle 104 continues to descend until the paddle 104 is separated from the vibration plate 105, and the vibration plate 105 recovers, causing the upper part of the vibration plate 105 to swing back and forth, synchronously driving the end of the material-pickling member 9, which has only one end fixed, to vibrate, and then the raw material slides along the protective cover 103 onto the partition 10, and the elastic member 102 recovers, synchronously driving the protective cover 103 to reset.

[0042] According to the above working steps, we know that the present invention has the following effects:

[0043] When the raw materials are placed on the partition 10, the raw materials are first rolled and crushed by the rolling roller 8 in cooperation with the partition 10. It is only necessary to replace the rolling rollers 8 of different weights. It has good adaptability to raw materials of different hardness. The powder raw materials after rolling are left on the partition 10, and then the powder raw materials are swept and gathered by the rotating hollow rubber hose 9002, and the gathered powder raw materials are driven to move together, and the powder crushed materials are transferred to the filter hole 1001 area on the partition 10. The powder crushed materials fall through each filter hole 1001 and are collected in the receiving hopper 5, so as to avoid the raw material powder from being retained on the partition 10 and being compacted after being repeatedly rolled by the rolling roller 8;

[0044] When the taut hollow rubber hose 9002 sweeps to the filter hole 1001, it sweeps away the excess powder material on the surface of the filter hole 1001, and also dredges the filter hole 1001 to prevent the filter hole 1001 from being blocked by the powder material.

[0045] When the rolling roller 8 is rolling and crushing the raw materials, some large particles of the raw materials will move with the rolling roller 8. At this time, by stopping pumping air into the rotating shaft 7 and releasing the air pressure in the rotating shaft 7, the hollow rubber hose 9002 is no longer tightened, the rotating shaft 7 is controlled to reverse, the raw material pile does not move with the rolling roller 8, and the raw material pile remains in place. Then the hollow rubber hose 9002 contacts the raw material pile, and the hollow rubber hose 9002 becomes soft and bends to bypass the raw material pile. At this time, air is pumped into the rotating shaft 7 again, and the rotating shaft 7 is controlled to rotate forward, so that the hollow rubber hose 9002 is tightened, and the hollow rubber hose 9002 can continue to sweep the raw material pile to continue moving. The hollow rubber hose 9002 sweeps the raw material pile to the filter hole 1001, and the crushed raw materials are discharged to the receiving hopper 5 through the filter hole 1001, while the raw materials that do not meet the particle size standards are continued to be swept by the hollow rubber hose 9002. , until the raw material leaves the filter hole 1001 area, the air pressure in the rotating shaft 7 is released, the hollow rubber hose 9002 becomes soft, the raw material is retained in place, and then the raw material is continued to be crushed and crushed by the subsequent rolling roller 8, so that the raw material powder that meets the crushing requirements is separated from the raw material with large particle size in time, to avoid the accumulation of raw materials on the partition 10, which affects the crushing of large particles of raw materials, and only one-fourth of the area of ​​the partition 10 is provided with a filter hole 1001 for screening the crushed raw material, and the remaining three-quarters of the area on the partition 10 is used to carry the crushing process of raw materials with different hardness, so that the crushing process and the screening process of the raw material are separated in space, and the raw material is not crushed in the filter hole 1001 area with weaker structural strength, which effectively avoids the deformation of the filter hole 1001 area and the problem of affecting the screening of the raw material.

[0046] By setting the protective cover 103 above the material-pickling piece 9 and setting the elastic piece 102, the falling raw materials are effectively blocked, so that when the raw materials fall on the protective cover 103, the protective cover 103 cooperates with the elastic piece 102 to cushion the raw materials, thereby preventing the raw materials from directly hitting the hollow material-pickling piece 9, causing the material-pickling piece 9 to deform and affecting the service life of the material-pickling piece 9. When the protective cover 103 moves downward, the paddle 104 contacts the vibration plate 105, causing the vibration plate 105 to vibrate, and simultaneously driving the material-pickling piece 9 fixed at only one end to vibrate, thereby shaking off the powder adhering to the hollow rubber hose 9002 and preventing the powder from gathering on the outer surface of the hollow rubber hose 9002.

[0047] On the basis of the above technical effects, the present invention also has the following advantages:

[0048] First, the protective cover 103 is in an inverted V-shape, which effectively blocks the falling raw materials and guides the raw materials to the partition plate 10 through the inclined surface thereof.

[0049] Second, the contact position between the paddle 104 and the vibration plate 105 is set to an arc shape, and the contact area between the paddle 104 and the vibration plate 105 is reduced, so that after the paddle 104 deforms the vibration plate 105, the paddle 104 is quickly separated from the vibration plate 105, avoiding the paddle 104 affecting the shaking of the vibration plate 105.

[0050] Thirdly, by setting a lifting knob at the lower part of the receiving hopper 5, the height of the receiving hopper 5 can be adjusted, and the upper part of the receiving hopper 5 is in contact with the crushing cylinder 3 to prevent the powder from escaping into the air, and a sealing rubber ring is set at the contact position between the receiving hopper 5 and the crushing cylinder 3, which helps to fully seal the blockage between the crushing cylinder 3 and the receiving hopper 5, reduce the dust from escaping into the air, and cause the loss of raw materials.

[0053] according to Figure 1-4 and Figure 8 As shown, it also includes a filter pore unblocking unit; the filter pore unblocking unit is connected to the partition 10; the filter pore unblocking unit is connected to the rotating shaft 7; the filter pore unblocking unit is connected to the movable plate 204; the filter pore unblocking unit includes an adapter sleeve 206 and a hose 207; the adapter sleeve 206 is bolted to the bottom of the partition 10; the adapter sleeve 206 is connected to the hollow rotating shaft 7; the adapter sleeve 206 is connected to the hose 207; an air cavity II 20401 is opened in the movable plate 204; the air cavity II 20401 is connected to the hose 207; the upper part of the air cavity II 20401 is opened with air holes, and each air hole corresponds to a filter hole 1001.

[0054] The working steps of the above embodiment are as follows:

[0055] In the description of the above embodiment, the crushed raw material needs to be transferred downward through the filter hole 1001, wherein the powdered raw material is swept to the filter hole 1001 area through the hollow rubber tube 9002, and the rotating shaft 7 is controlled to rotate, such as Figure 8 As shown, from top to bottom, the rotating shaft 7 rotates clockwise, the rotating shaft 7 drives the material-dispensing member 9 to rotate, and synchronously drives the lever 201 to rotate, so that the lever 201 contacts the contact rod 205, the lever 201 shifts the contact rod 205, the contact rod 205 drives the movable plate 204 to rotate in the movable groove 1002, and the tension spring 203 is stretched. When the movable plate 204 contacts the right limit portion 1003, the rotating shaft 7 continues to rotate, the lever 201 continues to rotate, and the rubber material of the lower part of the contact rod 205 begins to bend and deform until the lever 201 bypasses the contact rod 205, the tension spring 203 recovers, synchronously drives the contact rod 205 to reset, the contact rod 205 drives the movable plate 204 to reset, and makes the movable plate 204 hit the left limit portion 1003, and the powder raw material on the partition 10 continues to be discharged downward through the filter hole 1001;

[0056] And by setting a transfer sleeve 206 on the rotating shaft 7, as Figure 8 As shown, the adapter sleeve 206 is connected to the rotating shaft 7, so that the high-pressure air in the rotating shaft 7 is input into the air cavity II 20401 through the adapter sleeve 206 and the hose 207 in turn. When the movable plate 204 rotates to the bottom of the filter hole 1001, the air in the air cavity II 20401 is ejected to the corresponding filter hole 1001 through the air holes thereon, and the raw materials blocked at the filter hole 1001 are flushed open. When the movable plate 204 is reset, the movable plate 204 leaves the bottom of the filter hole 1001, and the air holes on the air cavity II 20401 are blocked by the partition 10.

[0057] According to the above working steps, we know that the present invention also has the following effects:

[0058] Due to the clockwise rotation of the rotating shaft 7, the lever 201 is synchronously driven to rotate. The lever 201 moves the contact rod 205, which also drives the movable plate 204 to move, so that the movable plate 204 rotates in the movable groove 1002. When the movable plate 204 moves in the movable groove 1002, the tension spring 203 is stretched. When the movable plate 204 contacts the right limiting portion 1003, the movement of the movable plate 204 and related parts thereon is restricted, and the rubber material of the lower part of the contact rod 205 begins to deform. After the lever 201 passes over the contact rod 205, the tension spring 203 is restored, and the movable plate 204 is synchronously pulled back quickly and hits the left limiting portion 1003, thereby causing the partition 10 to vibrate, so that the powder retained in the filter hole 1001 is discharged downward, and the filter hole 1001 is unblocked.

[0059] An air cavity II 20401 is opened in the movable plate 204, and the high-pressure air in the rotating shaft 7 is introduced into the air cavity II 20401. When the movable plate 204 rotates to below the filter hole 1001, the high pressure in the air cavity II 20401 is ejected through the air holes thereon. The ejected high-pressure air purges the corresponding filter hole 1001 and blows away the raw materials stuck in the filter hole 1001, thereby effectively preventing the filter hole 1001 from being blocked and affecting the discharge of the powder raw material.

[0060] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
