DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example 1

[0022] Reference Figure 1 , Figure 2A device for extracting astragalus polysaccharide from astragalus, comprising a substrate 1, and also comprising: a pressing cylinder 101, fixedly connected to the substrate 1; a cover plate 102, detachably connected to the pressing cylinder 101, wherein a discharge groove is provided on the pressing cylinder 101, a filter screen 104 is provided in the discharge groove, a pressing block 201 is slidably connected in the pressing cylinder 101, and a driving part for driving the pressing block 201 to move is provided on the pressing cylinder 101; a sliding cylinder 4, symmetrically fixedly connected to the substrate 1, wherein a sliding cylinder 4 is provided in the sliding cylinder 4. A piston disc 401 is connected, a support rod 402 is fixedly connected to the piston disc 401, a knocking rod 404 is fixedly connected to the support rod 402, a spring 403 is fixedly connected between the piston disc 401 and the bottom wall of the sliding cylinder 4, and the knocking rod 404 is located directly below the pressing cylinder 101; a pressing block 408 is fixedly connected to the knocking rod 404; a motor 406 is fixedly installed on the base plate 1, wherein a cam 407 is fixedly connected to the output end of the motor 406, and the cam 407 is against the pressing block 408.

[0023] The driving part comprises an electric telescopic rod 2 , which is fixedly mounted on the pressing cylinder 101 , and the pressing block 201 is fixedly connected to the output end of the electric telescopic rod 2 via a connecting rod 202 .

[0024] It also includes fixing bolts 103 , and the cover plate 102 is detachably connected to the pressing cylinder 101 via the fixing bolts 103 .

[0025] When in use, first add the crushed astragalus residue into the pressing cylinder 101, and then cover the cover 102 to achieve the purpose of closing the pressing cylinder 101, then screw on the fixing bolts 103, and then limit and fix the cover 102, and then start the electric telescopic rod 2, which drives the pressing block 201 to slide back and forth in the pressing cylinder 101 through the connecting rod 202, so as to achieve the effect of squeezing the astragalus residue, and then extract the astragalus polysaccharide liquid in the astragalus residue, and then when the squeezed astragalus polysaccharide liquid is discharged from the pressing cylinder 101 through the discharge chute, the particulate impurities in the astragalus polysaccharide liquid can be filtered out by the filter screen 104, and at the same time, start the motor 406, and the motor 406 drives the cam 407 to rotate. When the cam 407 abuts against the pressing block 408, The pressing block 408 is squeezed by the cam 407 to pull the knocking rod 404 downward, and at the same time, the knocking rod 404 pushes the piston plate 401 to slide downward in the sliding cylinder 4 through the support rod 402, and compresses the spring 403. Then, when the cam 407 is separated from the pressing block 408, the compressed spring 403 generates a thrust to push the piston plate 401 to slide upward in the sliding cylinder 4. At the same time, the piston plate 401 pushes the knocking rod 404 to move upward synchronously through the support rod 402, so that the knocking rod 404 knocks on the pressing cylinder 101 to generate vibration, thereby shaking off the astragalus residue adhering to the surface of the pressing block 201 and the cover plate 102, preventing the astragalus residue from adhering to the surface of the pressing block 201 and the cover plate 102, and affecting the extraction effect of the pressing block 201 on the polysaccharide liquid in the astragalus residue.

[0026] It should be noted that the pipe 2 501 is a stretchable hose, so the pipe 2 501 will not interfere with the removal or installation of the cover plate 102 . Example 2

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A device for extracting astragalus polysaccharide from astragalus is basically the same as Example 1, and further includes a pipeline 1 5 and a pipeline 2 501. The pipeline 1 5 is fixedly connected to the inner cavity of the sliding cylinder 4, and one end of the pipeline 2 501 is fixedly connected to the inner cavity of the sliding cylinder 4, and the other end passes through the cover plate 102 and is connected to the inner cavity of the pressing cylinder 101.

[0028] A filter box 3 is fixedly connected to the base plate 1 , a filter cloth 301 is arranged in the filter box 3 , a discharge pipe 302 is fixedly connected to the filter box 3 , a solenoid valve is arranged on the discharge pipe 302 , and the filter box 3 is located directly below the discharge trough.

[0029] Based on Example 1, when the piston disc 401 slides upward in the sliding cylinder 4, external gas is sucked into the sliding cylinder 4 through the pipe 1 5, so that the gas is temporarily stored, and then when the piston disc 401 slides downward in the sliding cylinder 4, the gas stored in the sliding cylinder 4 is squeezed by the piston disc 401 and transported into the pressing cylinder 101 through the pipe 2 501. Both the pipe 1 5 and the pipe 2 501 are provided with a one-way valve, so that the pressure inside the pressing cylinder 101 increases, thereby promoting the squeezed astragalus polysaccharide liquid to be quickly discharged from the pressing cylinder 101 through the discharge trough, thereby improving the efficiency of the initial filtration of the astragalus polysaccharide liquid, and then the astragalus polysaccharide liquid discharged from the pressing cylinder 101 falls into the filter box 3 and contacts the filter cloth 301, so that the astragalus polysaccharide liquid passes through the filter cloth 301 and falls into the bottom of the filter box 3, and the fine particulate impurities carried in the astragalus polysaccharide liquid are blocked on the surface of the filter cloth 301, thereby improving the quality of the astragalus polysaccharide liquid.

[0030] When it is necessary to take out the astragalus polysaccharide liquid after secondary filtration from the filter box 3, the solenoid valve on the discharge pipe 302 can be opened to allow the astragalus polysaccharide liquid to be discharged from the filter box 3 through the discharge pipe 302, thereby facilitating the removal of the filtered astragalus polysaccharide liquid from the filter box 3. Example 3

[0031] Reference Figure 1 , Figure 4 , a device for extracting astragalus polysaccharide from astragalus, is basically the same as Example 1, and further includes a sealing gasket 6, which is fixedly mounted on one end of a pressing cylinder 101 and fits with a cover plate 102; the sealing gasket 6 is closely fitted with the surface of the cover plate 102, thereby achieving the purpose of increasing the sealing performance of the connection between the cover plate 102 and the pressing cylinder 101, so as to prevent the squeezed astragalus polysaccharide liquid from leaking through the gap between the cover plate 102 and the pressing cylinder 101, thereby effectively reducing the waste of astragalus polysaccharide liquid.
