A circular screen plate is formed between the semicircular strips 114 and the corresponding screening strips 115. The screening strips 115 on the two semicircular strips 114 are arranged at intervals, and a complete circular extrusion plate is formed when the two semicircular strips 114 are fully joined.

[0040] Two adjusting screw rods 113 are rotatably mounted on the fan-shaped housing 105, and the adjusting screw rods 113 respectively form a spiral pair with the corresponding arc-shaped long plates 107. A limiting plate 120 is fixedly provided on one of the two arc-shaped long plates 107, and the limiting plate 120 is used to limit the position of the annular slide plate 121.

[0041] A positioning gear ring 112 is also rotatably installed on the outer side of the transposition motor 102, and a fan-shaped rack 116 and a fan-shaped strip plate 117 are fixedly installed on the positioning gear ring 112. The ends of the positioning screw rod 113 are fixedly installed with positioning gears 119. When the positioning gear 119 and the fan-shaped rack 116 are engaged, a gear rack pair is formed.

[0042] Under the action of the sector rack 116 and the sector strip 117, when the sector rack 116 and the adjusting gear 119 are engaged, the limiting circle 118 corresponding to the adjusting gear 119 is disengaged from the sector strip 117, and under the action of the tension spring 1 and the tension spring 2, the lower end face of the stirring rod 123 is always in contact with the upper surface of the circular extrusion plate, and the upper end face of the stirring rod 2 134 is always in contact with the lower surface of the circular extrusion plate.

[0043] In the initial position, the semicircular strips 114 are all located at the position closest to the supporting ring plate 124. At this time, a complete circular extrusion plate is formed between the two semicircular strips 114 and the screening strip 115. At this time, the tension spring between the annular slide plate 121 and the circular rotating plate 122 is in the initial state and has not been deformed. The spring between the annular rotating plate 135 and the annular slide plate 2 132 is in a stretched state. The limit plate 120 is always in contact with the annular slide plate 121, and the fan-shaped strips 117 and the two limit round blocks 118 are in a engaged state. At this time, the arc-shaped long plate 107 cannot move freely.

[0044] Open the fan-shaped cover 106, put the waste to be processed into the fan-shaped shell 105 and then close the fan-shaped cover 106, then start the transposition motor 102 to drive the transposition seat 103 to rotate, so that the fan-shaped shell 105 is in a vertical state, at this time the circular rotating plate 122 is located directly above the supporting ring plate 124, and at this time the waste is located between the extrusion circular plate 131 and the circular extrusion plate, then start the extrusion motor 129 to drive the extrusion circular plate 131 to move downward, the extrusion circular plate 131 presses and crushes the waste on the circular extrusion plate, and start the stirring motor 127 to drive the circular rotating plate 122 to rotate, the extrusion circular plate 131 and the stirring rod 123 rotate synchronously, and the waste is stirred under the action of the stirring rod 123, thereby improving the pressing and crushing effect.

[0045] After pressing and crushing for a certain period of time, the positioning motor 110 is started to drive the driving gear 111 to rotate, so that the positioning gear ring 112 rotates, and the fan-shaped rack 116 and the fan-shaped strip plate 117 on the positioning gear ring 112 rotate synchronously, so that the fan-shaped rack 116 rotates to engage with the positioning gear 119 corresponding to the arc-shaped long plate 107 on which the limiting plate 120 is set. At this time, the fan-shaped strip plate 117 is disengaged from the limiting round block 118 corresponding to the arc-shaped long plate 107.

[0046] The adjustment gear ring 112 continues to rotate, and the sector rack 116 drives the adjustment gear 119 corresponding to the arc-shaped long plate 107 to rotate, that is, the corresponding adjustment screw 113 rotates, so that the arc-shaped long plate 107 moves upward, and the semicircular strip plate 114 and the screening strip plate 115 corresponding to the arc-shaped long plate 107 move upward synchronously, that is, the circular screen plate formed by the semicircular strip plate 114 and the screening strip plate 115 moves upward, and the waste particles that meet the requirements fall along the screen slit of the screen plate to the circular plate formed by the supporting ring plate 124, the annular rotating plate 135, and the circular bottom plate 136. , waste particles that do not meet the requirements still remain on the circular sieve plate, and the arc-shaped long plate 107 moves upward and drives the circular rotating plate 122 to rotate, so that the stirring rod 123 stirs the residue on the circular sieve plate, so that the waste particles that meet the requirements can fully fall down, and the limit plate 120 on the arc-shaped long plate 107 moves upward synchronously while the arc-shaped long plate 107 moves, that is, the limit plate 120 releases the restriction on the position of the annular slide plate 121, and the stirring rod 123 can move upward synchronously with the arc-shaped long plate 107.

[0047] Under the action of the limiting plate 120, the lower end surface of the stirring rod 123 is always in contact with the upper surface of the circular screen plate corresponding to the arc-shaped long plate 107, thereby preventing the stirring rod 123 from moving under the action of waste.

[0048] When the circular screen plate moves to a quantitative position, the sector rack 116 disengages from the adjustment gear 119 corresponding to the arc long plate 107, and the arc groove on the limiting round block 118 corresponding to the arc long plate 107 is in the same circumferential direction as the sector strip 117, and the sector strip 117 is re-engaged with the limiting round block 118 corresponding to the arc long plate 107. Under the action of the sector strip 117, the limiting round block 118 and the adjustment gear 119 cannot rotate freely, that is, the position of the arc long plate 107 is locked, and the sector rack 116 continues to rotate, that is, the sector rack 116 is engaged with the adjustment gear 119 corresponding to another arc long plate 107. At this time, the sector strip 11 7 is disengaged from the limiting circular block 118. Under the action of the sector rack 116, the arc-shaped long plate 107 without the limiting plate 120 moves upward, and the semicircular strip plate 114 and the screening strip plate 115 on the arc-shaped long plate 107 move upward synchronously, and finally the semicircular strip plate 114 and the screening strip plate 115 are re-engaged to form a circular extrusion plate. At this time, the sector strip plate 117 is re-engaged with the two limiting circular blocks 118, that is, the positions of the two arc-shaped long plates 107 are locked. In the process of the arc-shaped long plate 107 without the limiting plate 120 moving upward, the stirring rod 134 moves upward synchronously, and the tension spring 2 between the annular slide plate 132 and the annular rotating plate 135 begins to recover.

[0049] Repeat the above steps so that the extrusion circular plate 131 presses and crushes the waste on the circular pressing plate again, and then repeat the above steps again so that the circular screen plate corresponding to the arc-shaped long plate 107 provided with the limiting plate 120 moves upward, that is, the waste after the secondary crushing is screened.

[0050] Continue to repeat the above steps to perform a third extrusion crushing on the waste, thereby achieving full extrusion crushing of the waste.

[0051] The waste particles after being squeezed and crushed are accumulated on the circular plate formed by the supporting ring plate 124, the annular rotating plate 135 and the circular bottom plate 136, and then the waste particles are disinfected and sterilized at high temperature through the fan-shaped heating plate 104, and the stirring motor 139 is started to drive the annular rotating plate 135 to rotate, so that the stirring rod 134 stirs the waste particles, thereby enabling the waste to be fully disinfected and sterilized.

[0052] Working principle: Start the transposition motor 102 to drive the transposition seat 103 to rotate, so that the fan-shaped shell 105 is in a horizontal state. At this time, the fan-shaped cover plate 106 is located directly above the base frame 101. The waste to be processed is placed into the fan-shaped shell 105 by controlling the fan-shaped cover plate 106. Then start the transposition motor 102 to rotate the fan-shaped shell 105 to a vertical state. The circular rotating plate 122 is located directly above the supporting ring plate 124.

[0053] Then, the extrusion motor 129 is started to move the extrusion circular plate 131 downward, that is, the waste is extruded and crushed for the first time, and the circular rotating plate 122 is driven to rotate, so that the stirring rod 123 stirs the waste, thereby improving the extrusion and crushing effect, and then the positioning motor 110 is started to move the two arc-shaped long plates 107 upward one by one, so as to screen the waste after extrusion and crushing, and then the above steps are repeated to perform the second and third extrusion and crushing on the waste, thereby achieving sufficient extrusion and crushing of the waste.

[0054] After the waste is squeezed and crushed, the fan-shaped shell 105 and the fan-shaped cover 106 are heated by the fan-shaped heating plate 104, that is, the waste particles are disinfected and sterilized at high temperature, and the stirring motor 139 is started to drive the annular rotating plate 135 to rotate, so that the stirring rod 134 stirs the waste particles, thereby improving the high-temperature disinfection and sterilization effect.

[0055] After completing the disinfection and sterilization of the waste particles inside the fan-shaped shell 105 and the fan-shaped cover plate 106, start the transposition motor 102 and the unfolding motor 109 to control the opening of the fan-shaped cover plate 106 and adjust the position of the fan-shaped shell 105, so that the waste particles inside the fan-shaped shell 105 and the fan-shaped cover plate 106 can be poured out, and a collection box can be set on the base frame 101 to effectively collect the poured waste particles.

[0056] 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.
