[0023] By setting the support frame 8, the crushing box 9 has a supporting effect.

[0024] By setting the telescopic rod 19, the fixed rod 15 is positioned and can also cooperate with the up and down movement.

[0025] By setting the double-shaft motor 11, when the double-shaft motor 11 is running, the rotation of one of the crushing rollers 12 can be controlled, and the model is set to 32GP-31ZY.

[0026] By setting the adjusting rod 7, the filtered food can be adjusted to avoid accumulation in the middle of the collection box 1, affecting the subsequent filtering process.

[0027] Further, the crushing box 9 is provided with a through hole 17 on the front surface, and one section of the fixed rod 15 is sleeved on the surface of the through hole 17.

[0028] Further, the spring 18 and the telescopic rod 19 are arranged in an upper and lower position, the bottom end of the spring 18 is fixedly connected in the crushing box 9, and the other end of the telescopic rod 19 rotates in the crushing box 9.

[0029] By setting the spring 18, when the disc 14 is not being extruded, the spring 18 can overcome the gravity to drive the disc 14, the extrusion rod and the beating plate 16 to move upward as a whole.

[0030] Further, the fixed rod 15 is fixedly connected with the disc 14 at the end away from the beating plate 16, and the long side of the extrusion plate 13 is connected with the surface of the disc 14.

[0031] By setting the disc 14, the extrusion plate can be contacted more smoothly by the circular arrangement.

[0032] Further, the two second support plates 2 are fixedly connected with the slide rod 6, and the surface of the slide rod 6 slides with the inner wall of the adjusting plate 5.

[0033] By setting the slide rod 6, the slide rod 6 limits the adjusting plate 5, so as to ensure the stable forward and backward movement of the adjusting plate 5.

[0034] Further, the right side of the crushing box 9 is provided with a mounting opening, and the observation door 22 is mounted in the mounting opening.

[0035] The working principle of this utility model is as follows: First, the operator connects the power supply to the dual-axis motor 11 and the servo motor 4. During operation, the dual-axis motor 11 controls one of the crushing rollers 12 to rotate, and through the meshing of the crushing roller 12, it drives the other crushing roller 12. At this time, the food to be crushed is placed downwards between the two crushing rollers 12, and the food is squeezed to complete the crushing process. The crushed food will fall downwards onto the filter screen 21. At the same time, the dual-axis motor 11 drives the extrusion disc 13 during operation. When the longer side of the extrusion disc 13 is downwards, it can drive the fixing rod 15 and the striking disc 16 to move downwards along the arc of the disc 14 surface. At the same time, the telescopic rod 19 is stretched, and the spring 18 is compressed. When the extrusion disc 13... When the side with the longer diameter stops rotating and presses downward against the disc 14, the spring 18 starts to use its own elasticity to control the fixed rod 15 and the striking disc 16 to move upward again, continuously striking the bottom of the filter screen 21 to generate vibration, accelerating the filtration of the pulverized food. The filtered food falls directly into the collection box 1 under the action of gravity. At this time, the servo motor 4 controls the reciprocating screw 3 to rotate, thereby driving the adjusting plate 5 and the adjusting rod 7 to move back and forth in a straight line, pushing the filtered food to both sides of the collection box 1, avoiding a large amount of food accumulating in the middle of the collection box 1, which would affect the subsequent normal filtration process. At the same time, the adjusting rod 7 in this device is set with a gap to effectively reduce the resistance during movement, ensuring a smoother and more fluid pushing of the food.

[0036] It should be noted that the interiors of the disc 14, the fixing rod 15, and the striking disc 16 are all hollow and made of aluminum alloy.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
