The driven gear 42 is meshed with the driving gear 26, and the driving gear 26 drives the driven gear 42 to rotate. The driven gear 42 drives the hollow wheel 39 and the short shaft 38 to rotate on the third bearing 37, and the hollow wheel 39 drives the arc plate 40 and the toggle shaft 41 on the arc plate 40 to rotate.

[0035] The toggle mechanism includes a toggle wheel 34 arranged on the rotating shaft 14, and an arc groove 35 and a U-shaped groove 36 are arranged on the toggle wheel 34, and the arc groove 35 and the U-shaped groove 36 are arranged alternately. When the hollow wheel 39 drives the arc plate 40 and the toggle shaft 41 to rotate, the toggle shaft 41 enters the U-shaped groove 36 and toggle the U-shaped groove 36 to rotate the toggle wheel 34. The design of the hollow wheel 39 is to enable the toggle shaft 41 to toggle the U-shaped groove 36 so that the U-shaped groove 36 is not affected inside the hollow wheel 39. When the side of the hollow wheel 39 opposite to the toggle shaft 41 rotates in the arc groove 35, the arc groove 35 cannot be toggled. At this time, the toggle wheel 34 does not rotate at this interval to achieve intermittent rotation of the hexagonal silo 6.

[0036] The working principle of the present invention is as follows: the button on the upper part of the spring latch 13 is pressed to make the latch end of the spring latch 13 pop out from the lock ring 12, and then the sealing door 11 is opened, and vegetables are put into each pressing bin 7. As more and more vegetables are put in, the pressing plates 17 and the top plate 9 on both sides of the vegetables are supported and move to both sides, the pressing plate 17 moves on the limit rod 16, the first spring 18 is compressed, the top plate 9 drives the top rod 20 and the circular plate 21 to move in the sleeve 19, the second spring 22 is compressed, and then the sealing door 11 is closed and locked by the spring latch 13 and the lock ring 12;

[0037] The pneumatic reduction motor 4 drives the worm 25 to rotate slowly, the worm 25 drives the worm wheel 24 to rotate, the first short rod 27 on the worm wheel 24 rotates synchronously with the worm wheel 24, the connecting rod 28 rotates on the first short rod 27 and the second short rod 31, and one end of the connecting rod 28 rotates with the rotation of the worm wheel 24, the connecting rod 28 drives the second short rod 31 to move up and down in the slide groove 20, the second short rod 31 drives the plate 32 in the fixed block 29, and the plate 32 drives the pressing block 33 to move up and down;

[0038] Synchronously, the worm 25 drives the driving gear 26 to rotate, the driving gear 26 drives the driven gear 42 to rotate, the driven gear 42 drives the hollow wheel 39, the hollow wheel 39 drives the short shaft 38 to rotate in the third bearing 37, the hollow wheel 39 drives the arc plate 40 and the shifting shaft 41 to rotate, the shifting shaft 41 enters the U-shaped groove 36 to shift the U-shaped groove 36 to rotate, the U-shaped groove 36 drives the shifting wheel 34 to rotate, the shifting wheel 34 drives the rotating shaft 14 to rotate in the second bearing 15, and the rotating shaft 14 drives the hexagonal silo 6 to rotate;

[0039] Synchronously, the pneumatic fan 2, the air flow generated by the fan 2 enters the rotating shaft 14 through the second bearing 15, and then enters the air cylinder 10. The air flow in the air cylinder 10 enters the pressing bin 7 through the air holes 23 on the air cylinder 10 and the pressing bin 7, and then blows the vegetables between the top plate 9 and the pressing plate 17 through the air holes 23 on the top plate 9. When the surface of the hollow wheel 39 opposite to the dial shaft 41 enters the arc groove 35, the hollow wheel 39 cannot move the arc groove 35 due to its self-rotation, and then cannot move the dial wheel 34 and the hexagonal bin 6. During this pause, one surface of the upper part of the hexagonal bin 6 faces upward, and accordingly makes the pressing plate 17 on the pressing bin 7 face upward. During this period, the pressing block 33 moves downward to press the pressing plate 17, and the pressing plate 17 moves toward the top plate 9 on the limit rod 16. The first spring 18 is stretched, so that the vegetables are squeezed out of the water inside by the top plate 9 and the pressing plate 17. It is worth noting that the pressing force of the pressing plate 17 is always smaller than the elastic force of the second spring 22, which ensures that when the pressing plate 17 is pressed, the top plate 9 will not move in the same direction with the pressing plate 17 to avoid squeezing the vegetables. The airflow generated by the fan 2 will spray the moisture on the surface of the vegetables and the moisture squeezed out of the vegetables, and blow them out of the hexagonal silo 6 through the air holes 23 on the pressing plate 17 to achieve the dehydration of the vegetables. After that, the pressing block 33 returns to its original position and disengages from the pressing plate 17. The pressing plate 17 rebounds and pulls back under the action of the first spring 18. The volume of the vegetables becomes smaller after dehydration. The top plate 9 moves toward the pressing plate 17 under the elastic force of the second spring 22, compacting the space vacated due to the smaller volume of the dehydrated vegetables, so that the pressing plate 17 and the top plate 9 will be closer when the pressing block 33 presses the pressing plate 17 next time, thereby squeezing the vegetables more tightly and achieving a better dehydration effect.

[0040] As the dial shaft 41 once again dials the next U-shaped groove 36, the dial wheel 34 and the hexagonal bin 6 rotate again, and the pressing bin 7 also switches to the next one, thus ensuring that the vegetables can be evenly distributed to each pressing bin 6 when pressed, and the vegetables are pressed evenly, avoiding accumulation so that the inner layer of vegetables cannot be fully pressed, resulting in poor vegetable dehydration effect, and intermittently pressing the vegetables in each pressing bin 7, ensuring that the vegetables in other pressing bins 7 that are not pressed have sufficient time to have the water blown out by the fan 2, avoiding excessive accumulation of water.

[0041] The present invention is simple to operate, convenient to use, and suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
