A slide plate 67 is slidably installed between the outsides of two adjacent fixed columns 64, and a spring is provided between the slide plate 67 and the fixed column 64. A number of connecting rods 66 are evenly and equidistantly fixed between the two slide plates 67, and a plug column 65 is fixed at the bottom of the number of connecting rods 66. The outer diameter of the plug column 65 is equal to the inner diameter of the drain pipe 62, and the plug column 65 is inserted into the drain pipe 62. The frame of the pressing box 4 is located on the movement trajectory of the slide plate 67. Through the arrangement of the above structure, the plug column 65 will push the spice raw material residue in the drain pipe 62 out of the drain pipe 62, so as to facilitate the pressing plate 61 to drive the U-shaped groove plate 63 and the drain pipe 62 to squeeze the spice raw materials next time.

The rods 74 are all installed in a transverse sliding manner inside the U-shaped groove plate 63, and a number of mesh plates 75 are evenly and equidistantly fixed at the bottom of the two U-shaped sliding rods 74, and the mesh plates 75 and the drainage pipe 62 are staggered. The top of the trapezoidal plate 71 is an inclined surface, and the end of the resistance rod 72 away from the U-shaped groove plate 63 is a semicircular shape. The inclined surface of the trapezoidal plate 71 is located on the semicircular movement trajectory of the resistance rod 72. Through the arrangement of the above structure, the mesh plates 75 form a shield above the drainage pipe 62, thereby preventing the spice raw material residue from entering the U-shaped groove plate 63 through the drainage pipe 62, causing the spice raw material residue in the U-shaped groove plate 63 to contaminate the squeezed liquid in the liquid receiving box 2.

The side of the triangular block 77 away from the center of the U-shaped groove plate 63 is set as an inclined surface, and the push pins 78 are located on the inclined surface movement trajectory of the triangular block 77. Through the setting of the above structure, the push pins 78 push the inclined surface of the triangular block 77 to drive the triangular block 77 to squeeze the sponge block 76. Part of the squeezed liquid adsorbed by the sponge block 76 is squeezed out and poured on the mesh plate 75, so that the squeezed liquid helps to clean the surface of the mesh plate 75, especially to remove the spice raw material residue that has been attached to the mesh plate 75.

[0022] When in use, the spice raw material is placed on the L-shaped filter screen 3, and the hydraulic cylinder 5 is started. The telescopic end of the hydraulic cylinder 5 pushes the pressing plate 61 to move downward, and the pressing plate 61 will squeeze the spice raw material on the L-shaped filter screen 3 in the squeezing box 4. The squeezed liquid extracted by squeezing the spice raw material will flow into the liquid receiving box 2. When the pressing plate 61 moves downward, it will drive the U-shaped groove plate 63 to move downward, and the squeezed liquid squeezed out of the upper layer of the spice raw material will flow into the U-shaped groove plate 63 through the drain pipe 62. Under the inverted V-shaped guiding effect of the U-shaped groove plate 63, the U-shaped groove plate 63 will drain the squeezed liquid to the two sides of the pressing plate 61, thereby accelerating the efficiency of squeezing, extracting and discharging the spice raw material; when the pressing plate 61 moves downward, it will also drive The fixed column 64 moves downward, and the fixed column 64 drives the slide plate 67 to move downward through the spring.

As the pressing plate 61 continues to move downward, the plug column 65 will separate from the drain pipe 62 at this time. When the hydraulic cylinder 5 is reset and drives the pressing plate 61 to move upward, the plug column 65 will overlap with the drain pipe 62 again. At the same time, the plug column 65 will push the spice raw material residue in the drain pipe 62 out of the drain pipe 62, thereby facilitating the pressing plate 61 to drive the U-shaped groove plate 63 and the drain pipe 62 to squeeze the spice raw materials next time.

[0023] After the plug 65 is separated from the drainage pipe 62 and the U-shaped groove plate 63 drives the resistance rod 72 to move to the trapezoidal plate 71, the inclined surface of the trapezoidal plate 71 pushes the semicircular shape of the resistance rod 72 to drive the resistance rod 72 to move in the direction of the U-shaped groove plate 63, and the resistance rod 72 pushes the elastic telescopic rod 73 to drive the U-shaped sliding rod 74 to move accordingly, and the U-shaped sliding rod 74 moves along the V-shape of the U-shaped groove plate 63 toward the center of the U-shaped groove plate 63, and the U-shaped sliding rod 74 drives the mesh plate 75 to move accordingly, and the mesh plate 75 will move to a position above the drainage pipe 62 and form a shield above the drainage pipe 62, thereby preventing the spice raw material residue from entering the U-shaped groove plate 63 through the drainage pipe 62, causing the spice raw material residue in the U-shaped groove plate 63 to contaminate the squeezed liquid in the liquid receiving box 2. It is worth noting that when the elastic telescopic rod 73 drives the U-shaped groove plate 63 to move, the telescopic end of the elastic telescopic rod 73 will be moved by the U-shaped groove plate When the U-shaped groove plate 63 is reset upward, the U-shaped groove plate 63 will drive the resistance rod 72 to separate from the trapezoidal plate 71, and the resistance rod 72 will be reset by the corresponding spring. The resistance rod 72 drives the mesh plate 75 to move away from the center of the U-shaped groove plate 63 through the elastic telescopic rod 73 and the U-shaped sliding rod 74. At this time, the pushing post 78 pushes the inclined surface of the triangular block 77 to drive the triangular block 77 to squeeze the sponge block 76. Part of the squeezed liquid absorbed by the sponge block 76 is squeezed out and poured onto the mesh plate 75, so that the squeezed liquid helps to clean the surface of the mesh plate 75, especially to remove the fragrance raw material residue already attached to the mesh plate 75.

[0024] See also Figure 1 - Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, a scraping device 8 is provided under the L-shaped filter screen 3.

The scraper shell 84 extracts the squeezed liquid in the spice raw material on the L-shaped filter 3, thereby further reducing the squeezed liquid content in the spice raw material, and the plug plate 87 pushes the air in the scraper shell 84 to be injected into the spice raw material. The air flows into the spice raw material, which can improve the ventilation performance of the spice raw material, thereby facilitating the discharge of the squeezed liquid from the filter cake spice raw material and promoting the squeezed liquid to squeeze out the spice raw material faster.

[0027] When in use, when the pressing plate 61 moves downward, it will drive the wavy groove plate 83 to move downward, and the wavy groove of the wavy groove plate 83 will push the L-shaped rod 82 to drive the telescopic end of the elastic telescopic plate 81 to move back and forth, and the telescopic end of the elastic telescopic plate 81 will drive the scraper shell 84 to move back and forth, so that the scraper shell 84 scrapes the bottom surface of the L-shaped filter 3, thereby improving the efficiency of discharging the squeezed liquid from the bottom surface of the L-shaped filter 3; each time the scraper shell 84 moves toward the fixed end of the elastic telescopic plate 81, the scraper shell 84 drives the U-shaped rod 86 to slide along the inside of the inclined groove of the inclined groove plate 85 through the plug plate 87. Under the restriction of the inclined groove of the inclined groove plate 85, the inclined groove of the inclined groove plate 85 drives the U-shaped rod 86 to pull the plug plate 87 to move downward along the inside of the scraper shell 84, and a negative pressure is formed inside the scraper shell 84, so that the scraper shell 84 extracts the spice raw materials on the L-shaped filter 3 The squeezed liquid is discharged from the scraper shell 84, thereby further reducing the squeezed liquid content in the spice raw material. When the U-shaped rod 86 pulls the plug plate 87 to move to the drain port 88, the squeezed liquid extracted from the scraper shell 84 will be discharged through the drain port 88, so that the scraper shell 84 can reciprocate to extract the squeezed liquid in the spice raw material. Each time the scraper shell 84 moves away from the fixed end of the elastic telescopic plate 81, the inclined groove of the inclined groove plate 85 drives the U-shaped rod 86 to push the plug plate 87 to move upward along the inside of the scraper shell 84. Since the squeezed liquid in the scraper shell 84 is discharged, there will be air in the scraper shell 84. The plug plate 87 will push the air in the scraper shell 84 to be injected into the spice raw material. The air flows into the spice raw material, which can improve the ventilation performance of the spice raw material, thereby facilitating the discharge of the squeezed liquid from the filter cake spice raw material and promoting the squeezed liquid to squeeze out the spice raw material faster.
