[0027] An extrusion barrel 105 is slidably mounted on the support ring plate 104, and an extrusion spring 135 is symmetrically arranged between the support ring plate 104 and the extrusion barrel 105. A circular slide plate 127 is slidably mounted on the inner side of the extrusion barrel 105, and a circular grinding disc 128 is fixedly mounted on the circular slide plate 127. The diameters of the circular grinding disc 128 and the circular slide plate 127 are equal. A strip bottom plate 130 is fixedly mounted on the end face of the extrusion barrel 105 farthest from the semicircular cover plate 106, and an extrusion slide is fixedly mounted on the end face of the circular slide plate 127 farthest from the semicircular cover plate 106. The support ring plate 104 is provided with an extrusion screw rod 109 which is rotatably mounted on the outer circumference of the support ring plate 104. The extrusion screw rod 109 and the extrusion slide 110 form a spiral pair. The support ring plate 104 is provided with an extrusion motor 108 which is fixedly mounted on the support ring plate 104. The output shaft of the extrusion motor 108 is fixedly connected to the extrusion screw rod 109.

[0028] A circular rotating plate 107 is also rotatably mounted on the supporting ring plate 104, a transposition gear ring 116 is fixedly mounted on the circular rotating plate 107, a transposition motor 118 is fixedly mounted on the supporting ring plate 104, a transposition gear 117 is fixedly mounted on the output shaft of the transposition motor 118, the transposition gear 117 and the transposition gear ring 116 are meshed to form a gear pair, a semicircular cover plate 106 is symmetrically slidably mounted on the circular rotating plate 107, a lifting slide plate 121 and a rake-shaped scraper 126 are slidably mounted on the semicircular cover plate 106, the lifting slide plate 121 and the rake-shaped scraper 126 are fixedly connected, a plurality of auxiliary square blocks 129 are evenly fixedly arranged at the junction of the semicircular cover plate 106 and the rake-shaped scraper 126, the width of the auxiliary square blocks 129 is equal to the screen gap width of the rake-shaped scraper 126, that is, the rake-shaped scraper 126 and the auxiliary square blocks 129 are slidably matched.

[0029] In the initial position, extrusion spring 134 and extrusion spring 2 135 are not compressed. At this time, the end face of the extrusion barrel 105 closest to the semicircular cover plate 106 and the end face of the semicircular cover plate 106 closest to the extrusion barrel 105 are not in contact, that is, at this time, there is a gap between the end face of the extrusion barrel 105 closest to the semicircular cover plate 106 and the end face of the semicircular cover plate 106 closest to the extrusion barrel 105, and the extrusion slide 110, the circular slide 127, and the circular grinding disc 128 are all located at the farthest position from the semicircular cover plate 106.

[0030] Start the extrusion motor 108 to drive the extrusion screw 109 to rotate, that is, the extrusion slide 110 moves toward the direction close to the semicircular cover plate 106. Since the sum of the elastic forces of the two extrusion springs 134 is always greater than the sum of the elastic forces of the two extrusion springs 135, at this time, under the action of the extrusion spring 134, the extrusion barrel 105, the extrusion slide 110, the circular slide plate 127, the circular grinding disc 128, and the strip bottom plate 130 move upward synchronously, that is, the extrusion barrel 105 moves toward the direction close to the semicircular cover plate 106, and the extrusion spring 134 is pressed against the bottom plate 130 to move upward. 135 is compressed, and finally the end face of the extrusion barrel 105 contacts the semicircular cover plate 106. At this time, the extrusion barrel 105 cannot move further, and the extrusion spring 135 reaches the maximum deformation and cannot be compressed further. The extrusion slide 110 continues to move, so that the extrusion spring 134 is compressed. The extrusion slide 110, the circular slide 127, and the circular grinding disc 128 move relative to the extrusion barrel 105 toward the direction close to the semicircular cover plate 106, that is, the circular slide 127 and the circular grinding disc 128 slide in the extrusion barrel 105.

[0031] An auxiliary component is also provided on the base 101, and the auxiliary component includes a cleaning scraper 113 and two auxiliary slides 115. The cleaning scraper 113 is used to clean the surface of the circular grinding disc 128. A cleaning slide 112 is fixedly installed on the cleaning scraper 113. The surface of the cleaning scraper 113 closest to the transposition motor 118 and the surface of the semicircular cover plate 106 closest to the extrusion barrel 105 are on the same plane. The cleaning slide 112 is slidably installed on the annular rotating plate 107, and a cleaning screw 111 is rotatably installed on the annular rotating plate 107. The cleaning screw 111 and the cleaning slide 112 constitute a spiral pair. A cleaning motor 119 is fixedly installed on the annular rotating plate 107, and the output shaft of the cleaning motor 119 is fixedly connected to the cleaning screw 111.

[0032] In the initial position, the cleaning slide 112 is located at the farthest position from the axis of the extrusion barrel 105. At this time, the cleaning scraper 113 is located on the side of the semicircular cover plate 106. The length of the cleaning scraper 113 is greater than the inner diameter of the extrusion barrel 105. When the two semicircular cover plates 106 are located at the farthest position, the distance between the two semicircular cover plates 106 is greater than the length of the cleaning scraper 113. At this time, the cleaning motor 119 is started to drive the cleaning screw 111 to rotate, so that the cleaning slide 112 moves toward the direction close to the axis of the extrusion barrel 105, and the cleaning scraper 113 moves synchronously, that is, the end face of the extrusion barrel 105 closest to the semicircular cover plate 106 is scraped and cleaned.

[0033] Two auxiliary slides 115 are symmetrically slidably installed on the annular rotating plate 107, and auxiliary screw rods 114 are symmetrically rotatably installed on the annular rotating plate 107. The auxiliary slides 115 and the corresponding auxiliary screw rods 114 form a spiral pair respectively. A double-headed motor 120 is also fixedly installed on the annular rotating plate 107. The output shafts at both ends of the double-headed motor 120 are fixedly connected to the corresponding auxiliary screw rods 114 respectively. The spiral directions of the two auxiliary screw rods 114 are opposite. Starting the double-headed motor 120 drives the two auxiliary screw rods 114 to rotate synchronously, that is, the two auxiliary slides 115 move in a direction close to each other or in a direction away from each other. An auxiliary side plate 132 is fixedly arranged on the auxiliary slide 115. The auxiliary side plate 132 is slidably matched with the corresponding semicircular cover plate 106, and two adjustment springs 136 are arranged between the auxiliary side plate 132 and the corresponding semicircular cover plate 106.

[0034] A lifting unit is arranged between the auxiliary side plate 132 and the corresponding lifting slide plate 121, and the lifting unit includes two lifting gears 125, and the two lifting gears 125 are rotatably installed on the corresponding semicircular cover plate 106 respectively. A lifting rack 124 is fixedly installed on the auxiliary side plate 132, and the lifting rack 124 and the corresponding lifting gear 125 are meshed to form a gear rack pair. A lifting rotating plate 122 is rotatably installed on the lifting gear 125, and a torsion spring is arranged between the lifting rotating plate 122 and the lifting gear 125, one end of the torsion spring is fixedly connected to the lifting rotating plate 122, and the other end of the torsion spring is fixedly connected to the lifting gear 125, and a positioning short rod 123 is fixedly arranged on the lifting slide plate 121, and the lifting rotating plate 122 is movably connected to the corresponding positioning short rod 123.

[0035] The limit springs 133 are symmetrically arranged between the lifting slide plate 121 and the corresponding semicircular cover plate 106. The elastic force of the torsion spring between the lifting turn plate 122 and the lifting gear 125 is always greater than the sum of the elastic forces of the two limit springs 133 on the same semicircular cover plate 106. The sum of the elastic forces of the two adjusting springs 136 on the same semicircular cover plate 106 is always greater than the sum of the elastic forces of the two limit springs 133.

[0036] In the initial position, the two semicircular cover plates 106 are located at the farthest position from each other, the lifting slide plate 121 is located at the closest position to the lower surface of the semicircular cover plate 106, the limit springs 133 are not compressed, the torsion spring between the lifting turn plate 122 and the lifting gear 125 is not compressed, the two auxiliary side plates 132 are located at the closest position to each other, and the adjustment springs 136 between the auxiliary side plates 132 and the semicircular cover plates 106 are in a compressed state. When the end face of the extrusion barrel 105 contacts the semicircular cover plate 106, a closed chamber is formed between the extrusion barrel 105, the semicircular cover plate 106, and the circular grinding disc 128, and at this time, the end of the rake scraper 126 closest to the circular grinding disc 128 contacts the circular grinding disc 128, and the end faces of the two rake scrapers 126 closest to the inner circumferential surface of the extrusion barrel 105 contact the inner circumferential surface of the extrusion barrel 105.

[0037] Starting the double-headed motor 120 drives the two auxiliary screw rods 114 to rotate, so that the two auxiliary slides 115 move away from each other, that is, the two auxiliary side plates 132 move away from each other. Since the sum of the elastic forces of the two adjusting springs 136 on the same semicircular cover plate 106 is always greater than the sum of the elastic forces of the two limit springs 133 and the elastic force of the torsion spring between the lifting rotating plate 122 and the lifting gear 125 is always greater than the sum of the elastic forces of the two limit springs 133 on the same semicircular cover plate 106, the two adjusting springs 136 begin to recover at this time, that is, the auxiliary side plates 132 move relative to the corresponding semicircular cover plate 106, and the lifting rack 124 moves synchronously, so that the corresponding lifting gear 125 rotates.

[0038] Under the action of the torsion spring between the lifting gear 125 and the lifting rotating plate 122, the lifting rotating plate 122 and the lifting gear 125 rotate synchronously. Under the action of the lifting rotating plate 122, the adjusting short rod 123 moves in the direction away from the semicircular cover plate 106, the lifting slide plate 121 and the rake scraper 126 move synchronously, the limit spring 133 is compressed, and finally the adjusting spring 136 is completely restored. At this time, the auxiliary side plate 132 moves to the position farthest from the corresponding lifting slide plate 121. Under the action of the lifting rotating plate 122, the adjusting short rod 123, the lifting rack 124, and the lifting gear 125, the lifting slide plate 121 moves to the position farthest from the lower surface of the semicircular cover plate 106. At this time, the end of the rake scraper 126 closest to the circular grinding disc 128 and the surface of the semicircular cover plate 106 closest to the circular grinding disc 128 are on the same plane. At this time, the rake scraper 126 slides relative to the auxiliary square block 129.

[0039] The two auxiliary side panels 132 continue to move away from each other, because at this time the auxiliary side panels 132 have moved to the farthest position from the corresponding lifting slide 121, that is, at this time the auxiliary side panels 132 cannot slide relative to the semicircular cover plate 106, and at this time the auxiliary side panels 132 and the corresponding semicircular cover plates 106 slide synchronously, that is, the two semicircular cover plates 106 move away from each other, and finally the two semicircular cover plates 106 move to the farthest position.

[0040] Working principle: Start the dumping motor 103 to drive the corresponding transmission shaft 131 to rotate, that is, the supporting ring plate 104 rotates, so that the extrusion barrel 105 is in a vertical upward state, and then start the double-headed motor 120 to drive the two auxiliary screw rods 114 to rotate, so that the two auxiliary slides 115 move away from each other, first moving the lifting slide 121 and the rake scraper 126 to the farthest position from the circular grinding disc 128, and the two auxiliary slides 115 continue to move, so that the two semicircular cover plates 106 move to the farthest position.

[0041] Then, the plants to be crushed are added into the extrusion barrel 105, and the plants added into the extrusion barrel 105 are accumulated on the circular grinding disc 128. After a certain amount of plants are added into the extrusion barrel 105, the double-headed motor 120 is started to move the two semicircular cover plates 106 to the closest position. At this time, the lifting slide 121 and the rake scraper 126 move to the closest position to the circular grinding disc 128, and the rake scraper 126 is inserted into the inside of the plants placed in the extrusion barrel 105. Then, the extrusion motor 108 is started to move the extrusion slide 110 upward, so that the end face of the extrusion barrel 105 contacts the semicircular cover plate 106. At this time, the extrusion barrel 105, the semicircular cover plate 106, and the circular grinding disc 128 form a sealed chamber.

[0042] Continue to drive the extrusion slide 110 to move upward, that is, the circular slide 127 and the circular grinding disc 128 move upward relative to the extrusion barrel 105, and the circular grinding disc 128 makes the inside of the extrusion barrel 105 move upward. Under the action of the semicircular cover plate 106, the plants placed inside the extrusion barrel 105 are squeezed. Under the action of the circular grinding disc 128, the two rake-shaped scrapers 126 move upward synchronously, that is, the lifting slide 121 moves upward, and the limit spring 133 is compressed. Under the action of the adjusting short rod 123, the lifting rotating plate 122 rotates. At this time, the lifting gear 125 cannot rotate, that is, the torsion spring between the lifting rotating plate 122 and the lifting gear 125 is compressed.

[0043] Then, the transposition motor 118 is started to drive the transposition gear 117 to rotate. Under the action of the transposition gear ring 116, the annular rotating plate 107 is rotated. Since the semicircular cover plate 106 is slidably installed on the annular rotating plate 107, the semicircular cover plate 106 rotates synchronously at this time, that is, the rake scraper 126 on the semicircular cover plate 106 rotates synchronously. Under the action of the rake scraper 126, the plants placed inside the extrusion barrel 105 rotate inside the extrusion barrel 105. During the movement of the plants inside the extrusion barrel 105, they contact the upper surface of the circular grinding disc 128, and the plants are crushed under the action of the circular grinding disc 128. During the movement of the rake scraper 126 relative to the semicircular cover plate 106, the semicircular cover plate 106 and the auxiliary square block 129 scrape and clean the screen gap of the rake scraper 126, thereby preventing the rake scraper 126 from carrying the crushed plants.

[0044] After the plants are crushed, the dumping motor 103 is started to drive the supporting ring plate 104 to rotate 180 degrees, so that the end face of the extrusion barrel 105 farthest from the circular grinding disc 128 is located closest to the lower surface of the base 101, and then the double-headed motor 120 is started to move the two auxiliary screw rods 114 away from each other, first moving the two lifting slides 121 and the rake scraper 126 to the farthest position from the circular grinding disc 128, and then moving the two semicircular cover plates 106 to the farthest position. The crushed plants fall into the collecting box 102 below, and during the movement of the semicircular cover plate 106, the extrusion barrel 105 also scrapes off the plants attached to the surface of the semicircular cover plate 106, and then starts the extrusion motor 108 to drive the extrusion slide 110 to move toward the extrusion barrel 105, so that the circular grinding disc 128 continues to move downward, and finally the end face of the circular grinding disc 128 and the end face of the extrusion barrel 105 are on the same plane. At this time, the plants that have been crushed in the extrusion barrel 105 fall into the collecting box 102 below under the action of the circular grinding disc 128.

[0045] Then the cleaning motor 119 is started to drive the cleaning carriage 112 and the cleaning scraper 113 to move synchronously. Under the action of the cleaning scraper 113, the plants attached to the end surfaces of the extrusion barrel 105 and the circular grinding disc 128 are scraped and cleaned.

[0046] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
