Description

Technical Field

[0001] This invention relates to the field of straw crushing and pulping technology, and in particular to a straw pulping device for the production of biodegradable lunch boxes. Background Technology

[0002] With increasing environmental awareness and the pursuit of sustainable development, biodegradable lunch boxes, as an ideal alternative to traditional plastic lunch boxes, are seeing a continuous rise in market demand. Biodegradable lunch boxes, with their ability to decompose in the natural environment and reduce environmental pollution, are gradually becoming a new favorite in the catering industry. Straw, as an abundant and renewable agricultural waste, possesses excellent fiber properties, making it a high-quality raw material for producing biodegradable lunch boxes. This not only helps solve the environmental pollution problem caused by straw burning but also achieves efficient resource utilization, bringing significant economic and environmental benefits.

[0003] Most existing pulping devices only have a single crushing function, making it difficult to accurately control the fineness of the ground fibers. This fails to meet the diverse fiber raw material requirements of different biodegradable food container products, thus affecting the performance and quality of the food containers. In the process of mixing fibers and water to form a pulp, the stirring method is often relatively simple, resulting in uneven mixing of fibers and water, affecting the stability and uniformity of the pulp. Moreover, during the stirring process, the state of the pulp can only be observed with the naked eye most of the time, making it difficult to accurately judge the degree of pulp formation.

[0004] Therefore, it is necessary to design a straw pulping device that can adjust the fineness of the ground fibers as needed to meet the diverse raw material requirements of different lunch box products, and can determine the degree of pulp formation, so as to solve the problem that the existing device is difficult to adjust the fineness of the ground fibers and is difficult to accurately determine the degree of pulp formation. Summary of the Invention

[0013] Preferably, the device also includes a crushing mechanism frame for crushing the cleaned straw, a crushing box, a control motor, a crushing inner cylinder, a connecting channel, a crushing rod, rotating crushing blades, and an anti-jamming component. The frame is located on the left side of the pulping cylinder. The crushing box is installed on the frame, and the control motor is installed inside the frame. The crushing rod is rotatably connected inside the crushing box, and the crushing inner cylinder is fixed inside the crushing box.

The output shaft of the control motor is connected to the crushing rod, and rotating crushing blades are fixed on the crushing rod. The anti-jamming component is installed inside the crushing box.

[0014] Preferably, the anti-jamming assembly includes a wedge-shaped rotating block, a second torsion spring, a lifting block, a lifting cylinder, a splined shaft, a rotating rod, and a sliding baffle.

The bottom of the sliding adjusting rod is fixedly connected to the lifting extrusion plate, and the top of the sliding adjusting rod passes through the discharge frame and is slidably connected to the rotating screen plate.

[0016] The beneficial effects of this invention are: 1. This device can adjust the position of the inner grinding block and change the distance between the inner grinding block and the outer grinding cylinder to grind straw fibers of different coarseness. When adding material into the pulping cylinder, the rotating magnetic block cooperates with the reset spring to make the sliding magnetic plate slide back and forth at the top inlet of the pulping cylinder, continuously opening and closing the top inlet of the pulping cylinder to avoid material blockage at the top inlet of the pulping cylinder. After grinding, the shaking screen plate can screen the ground material, and when the shaking screen plate slides up and down, it can cooperate with the lifting extrusion plate to perform secondary extrusion on the straw that is not completely ground.

[0017] 2. During the pulping process, the tilt angle of the stirring rod can be adjusted according to the fiber thickness to ensure that the resistance experienced by the stirring rod in the pulp is the same after the final mixing is completed. After the pulp is fully formed, due to the resistance of the pulp on the stirring rod, a speed difference will be formed between the lifting block and the upper rotating block. The upper rotating block pushes the lifting block to slide downward to provide sufficient pressure to the pressure sensor. The pressure sensor can then transmit a signal to indicate that the pulp has formed, thus realizing the function of indicating that the pulp has formed.

[0018] 3. During the straw crushing process, when too much straw clogs the upper part of the crushing inner cylinder, the rotating crushing blades on the wedge-shaped rotating block experience increased resistance, causing their rotation speed to decrease. This creates a certain speed difference between the wedge-shaped rotating block and the lifting block. The lifting block rises and, through the lifting cylinder and rotating rod, causes the sliding baffle to slide downward and close the crushing chamber inlet, preventing further straw from entering the crushing chamber. After the clogged straw is crushed, the wedge-shaped rotating block automatically returns to its original position and the sliding baffle rises back to its original position, allowing external straw to re-enter the crushing chamber, thus preventing the equipment from becoming clogged and stuck.

[0019] 4. The crushed straw is screened by a rotating screen plate. The material screened by the rotating screen plate directly enters the pulping drum. The tilt angle of the rotating screen plate is adjusted according to the required fiber coarseness. Since the time required to grind different fiber coarsenesses is different, the finer the fiber, the smaller the tilt angle of the rotating screen plate, and the slower the rolling speed of the crushed straw, so as to prevent too much straw from entering the inner grinding blocks in the pulping drum. When the required fiber is coarser, the grinding speed is faster, the tilt angle of the rotating screen plate is larger, and the rolling speed of the crushed straw is increased, so that the speed of adding straw matches the grinding speed.

[0033] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0034] Example 1: A straw pulping device for the production of biodegradable lunch boxes, such as Figures 1-12As shown, the system includes a pulping cylinder 1, a grinding outer cylinder 101, a rotating cylinder 102, a rotating magnetic block 1021, a sliding magnetic plate 103, a return spring 104, a protective cover 105, an inner grinding block 106, an adjusting mechanism, a screening mechanism, and a pulping mechanism. The grinding outer cylinder 101 is fixedly connected inside the pulping cylinder 1, and the rotating cylinder 102 is rotatably connected inside the pulping cylinder 1. The rotating cylinder 102 is driven to rotate by an external power source. The rotating magnetic block 1021 is connected to the rotating cylinder 102 via a pull rope. When the rotating cylinder 102 rotates, the rotating magnetic block 1021 is subjected to centrifugal force and rises, straightening the pull rope. A sliding magnetic plate 103 is slidably connected at the top inlet of the pulping cylinder 1. A return spring 104 is provided between the sliding magnetic plate 103 and the pulping cylinder 1. The two ends are fixed to the sliding magnetic plate 103 and the pulping cylinder 1, respectively. The rotating cylinder 102 is slidably connected to the inner grinding block 106, which can rotate with the rotating cylinder 102. A protective cover 105 is fixed to the inner grinding block 106. The outer surface of the protective cover 105 is conical, so that the material entering the pulping cylinder 1 rolls between the inner grinding block 106 and the outer grinding cylinder 101. An adjustment mechanism is installed in the pulping cylinder 1. The adjustment mechanism is used to adjust the distance between the outer grinding cylinder 101 and the inner grinding block 106 to adjust the coarseness of the ground fibers. A screening mechanism is installed in the pulping cylinder 1. The screening mechanism screens the ground fibers. A pulping mechanism is installed in the pulping cylinder 1. The pulping mechanism is used to mix the fibers with water to form a pulp.

[0035] The rotating drum 102 is driven to rotate by an external power source. During the rotation of the rotating drum 102, the two rotating magnetic blocks 1021 are subjected to centrifugal force, which straightens the pull rope. The magnetic properties of the end faces of the rotating magnetic blocks 1021 and the sliding magnetic plate 103 are opposite. When the rotating magnetic blocks 1021 approach the sliding magnetic plate 103, the sliding magnetic plate 103 is slid inside the pulping drum 1 by the magnetic force of the rotating magnetic blocks 1021 and compresses the return spring 104. The sliding magnetic plate 103 slides away from the inlet of the pulping drum 1 to open the top inlet of the pulping drum 1, so that the crushed straw enters the pulping drum 1 through the top inlet. During the process of adding materials, the rotating magnetic blocks 1021 and the return spring 104 cooperate to make the sliding magnetic plate 103 slide back and forth inside the pulping drum 1, so that the top inlet of the pulping drum 1 opens and closes continuously. When the sliding magnetic plate 103 slides along the pulping drum 1 and closes its top inlet, the sliding magnetic plate 103 will push the crushed straw at the inlet of the pulping drum 1. To prevent straw from getting stuck at the inlet of the pulping cylinder 1, the straw will roll along the protective cover 105 between the outer grinding cylinder 101 and the inner grinding block 106. When the rotating cylinder 102 rotates, it will drive the inner grinding block 106 to rotate. During the rotation of the inner grinding block 106, it will work with the outer grinding cylinder 101 to grind the straw and separate the fibers in the straw. The ground straw fibers will fall down from between the outer grinding cylinder 101 and the inner grinding block 106 into the screening mechanism. When it is necessary to adjust the coarseness of the ground straw fibers, the adjustment mechanism is operated to make the inner grinding block 106 slide up and down along the rotating cylinder 102 to adjust the distance between the outer grinding cylinder 101 and the inner grinding block 106. The screening mechanism screens the ground straw fibers. The screened fibers enter the pulping mechanism. Water is added to the pulping mechanism at the same time as the pulping mechanism is started, so that the fibers and water are mixed evenly to form a fiber pulp. After pulping is completed, the formed pulp is taken out from the pulping mechanism.

[0036] Example 2: Based on Example 1, such as Figure 2 and Figure 3As shown, the adjustment mechanism includes a U-shaped sliding frame 107, a rotating connecting rod 108, a rotating sleeve 109, an electric push rod 2, a connecting push plate 201, and a lifting extrusion plate 202. The U-shaped sliding frame 107 is slidably connected inside the rotating cylinder 102. The U-shaped sliding frame 107 passes through the rotating cylinder 102 and extends outward. The rotating connecting rod 108 is rotatably connected to the outward-extending support rod of the rotating cylinder 102. A slotted sliding hole is opened at both ends of the rotating connecting rod 108. The straight rod at the top of the inner grinding block 106 passes through the slotted sliding hole on the corresponding side of the rotating connecting rod 108 and is slidably connected thereto. The straight rod on the U-shaped sliding frame 107 passes through the slotted sliding hole on the other side of the rotating connecting rod 108 and is slidably connected thereto. A rotating sleeve 109 is slidably connected inside the rotating cylinder 102. The rotating sleeve 109 is fixedly connected to the U-shaped sliding frame 107. An electric push rod 2 is installed outside the pulping cylinder 1. A connecting push plate 201 is slidably connected to the pulping cylinder 1. The connecting push plate 201 extends into the pulping cylinder 1 and is fixedly connected to a lifting extrusion plate 202. The telescopic shaft of the electric push rod 2 is fixedly connected to the connecting push plate 201. The electric push rod 2 can drive the lifting extrusion plate 202 to move up and down through the connecting push plate 201. The rotating sleeve 109 passes through the lifting extrusion plate 202 and is rotatably connected to it through a bushing. When the lifting extrusion plate 202 moves up and down, it can drive the rotating sleeve 109 to slide up and down in the rotating cylinder 102.

[0037] When it is necessary to adjust the fineness of the ground fibers, the electric push rod 2 is activated. The electric push rod 2 drives the lifting extrusion plate 202 to slide up and down along the pulping cylinder 1 through the connecting push plate 201. When the lifting extrusion plate 202 is pushed up, it drives the U-shaped sliding frame 107 to slide upward through the rotating sleeve 109. When the U-shaped sliding frame 107 slides upward, it can drive the inner grinding block 106 to slide downward through the rotating connecting rod 108, so as to reduce the distance between the inner grinding block 106 and the grinding outer cylinder 101, making the ground fibers finer. When the lifting extrusion plate 202 is driven down, it drives the U-shaped sliding frame 107 to slide downward through the rotating sleeve 109. When the U-shaped sliding frame 107 slides downward, it can drive the inner grinding block 106 to slide upward through the rotating connecting rod 108, so as to increase the distance between the inner grinding block 106 and the grinding outer cylinder 101, making the ground fibers coarser.

[0038] like Figure 2 and Figure 3As shown, the screening mechanism includes a vibrating screen plate 203, a support spring 204, a fixed protrusion 2041, a sliding pressing frame 205, a rotating protrusion 2051, and a connecting spring 2052. The vibrating screen plate 203 is slidably connected inside the pulping cylinder 1. The bottom edge of the screen holes in the vibrating screen plate 203 is rounded. A conical block is fixed to the top of the lifting extrusion plate 202. The surface of the conical block is a friction layer, and the conical block at the top of the lifting extrusion plate 202 cooperates with the screen holes on the vibrating screen plate 203. A support spring 204 is provided between the vibrating screen plate 203 and the pulping cylinder 1. The two ends of the support spring 204 are respectively fixed to the vibrating screen plate 203 and the pulping cylinder 1. The rotating sleeve 1... 09 passes through and is rotatably connected to the vibrating screen plate 203, and the vibrating screen plate 203 can slide up and down along the rotating sleeve 109. A fixed protrusion 2041 is fixedly connected to the vibrating screen plate 203 near the rotating cylinder 102. A sliding pressure frame 205 is slidably connected to the rotating cylinder 102. A connecting spring 2052 is provided between the sliding pressure frame 205 and the rotating cylinder 102. The two ends of the connecting spring 2052 are fixed to the sliding pressure frame 205 and the rotating cylinder 102 respectively. A rotating protrusion 2051 is fixedly connected to the sliding pressure frame 205. During the rotation of the sliding pressure frame 205, the rotating protrusion 2051 will contact the fixed protrusion 2041.

[0039] When adjusting the fineness of the ground fibers, the distance between the conical block on the lifting extrusion plate 202 and the screen holes on the vibrating screen plate 203 also changes accordingly. The ground fibers fall onto the vibrating screen plate 203. When the rotating cylinder 102 rotates, it drives the sliding lower pressure frame 205 to rotate. During the rotation of the sliding lower pressure frame 205, the rotating protrusion 2051 will contact the fixed protrusion 2041. At this time, the elastic force of the connecting spring 2052 is greater than the elastic force of the supporting spring 204. The sliding lower pressure frame 205 will push the fixed protrusion 2041 and the vibrating screen plate 203 downward through the rotating protrusion 2051 and compress the supporting spring 204. When the vibrating screen plate 203 descends to the point of contacting the top surface of the lifting extrusion plate 202, the vibrating screen plate 203 can no longer descend. At this time, the sliding lower pressure frame 205 will slide upward along the rotating cylinder 102 and compress the connecting spring 2052. When the rotating protrusion 2051 rotates past the fixed protrusion... After reaching the highest point at 2041, as the sliding pressure frame 205 continues to rotate with the rotating cylinder 102, the connecting spring 2052 pushes the sliding pressure frame 205 to slide downwards and reset along the connecting cylinder. Subsequently, the support spring 204 pushes the vibrating screen plate 203 to slide upwards and reset. During the rotation of the sliding pressure frame 205, the vibrating screen plate 203 continuously vibrates up and down to screen the ground fibers. As the thickness of the ground fibers changes, the distance between the lifting extrusion plate 202 and the vibrating screen plate 203 also changes. Since the lower edge of the screen hole of the vibrating screen plate 203 is rounded, the conical block on the lifting extrusion plate 202 corresponds exactly to the screen hole on the vibrating screen plate 203. During the up and down vibration of the vibrating screen plate 203, the friction layer on the outer surface of the conical block on the lifting extrusion plate 202 can squeeze and rub the fibers stuck in the screen hole of the vibrating screen plate 203 to perform secondary squeezing and grinding of the fibers that have not been ground properly.

[0040] like Figure 4 As shown, it also includes a fan 206. The fan 206 is slidably connected to the outside of the rotating sleeve 109. The fan 206 rotates with the rotating sleeve 109 to prevent the ground straw fibers from clogging the sieve holes on the shaking sieve plate 203.

[0041] The pulping cylinder 1 has an air outlet on its side. The air outlet is located inside the pulping cylinder 1, below the fan 206 and above the height of the pulp. A screen is also installed at the air outlet to prevent fibers from falling outward with the airflow. During the screening process, the fan 206 rotates continuously to drive the airflow at the top downward, adsorbing some of the fibers scattered on the shaking screen plate 203 away from the screen holes to the screen holes for screening, so as to avoid fiber residue.

[0042] like Figures 4-6As shown, the pulping mechanism includes a rotating shaft 1091, a rotating bushing 207, an agitator 2071, an adjusting component, and a pressure sensing component. The rotating shaft 1091 is rotatably connected inside the pulping cylinder 1. The rotating shaft 1091 passes through and is slidably connected to the rotating bushing 109, and the rotating shaft 1091 can rotate with the rotating bushing 109. The rotating bushing 207 is installed on the rotating shaft 1091, and the agitator 2071 is rotatably connected to the outside of the rotating bushing 207. The agitator 2071 fully agitates the ground straw fibers and water. The adjusting component is installed outside the rotating shaft 1091 and is used to adjust the tilt angle of the agitator 2071. The pressure sensing component is installed outside the rotating shaft 1091 and is used to sense the degree of mixing between the fibers and water.

[0043] like Figure 4 and Figure 12 As shown, the adjustment assembly includes a connecting rod 2061, a connecting rotating rod 2072, and a connecting block 2074. The connecting rod 2061 rotates at the bottom of the central turntable of the fan 206. Two connecting blocks 2074 are fixedly attached to each stirring rod 2071. The other end of the connecting rod 2061 is rotatably connected to the connecting block 2074 on the corresponding side of the stirring rod 2071. The connecting blocks 2074 on the stirring rods 2071 located on the same vertical plane are connected through the connecting rotating rod 2072 to synchronously adjust the tilt angle of the stirring rods 2071 at different heights.

[0044] like Figure 5 and Figure 6 As shown, the pressure sensing assembly includes an upper rotating block 2073, a protective housing 208, a lifting rotating block 2081, a first torsion spring 2082, and a fixed disk 209. The fixed disk 209 is fixedly connected to the outside of the rotating shaft 1091, and the protective housing 208 is fixedly connected to the fixed disk 209. A pressure sensor is installed on the top surface of the fixed disk 209 inside the protective housing 208. The top of the protective housing 208 contacts the rotating bushing 207, and the upper rotating block 2073 is fixedly connected to the bottom of the rotating bushing 207. The upper rotating block 2073 is located inside the protective housing 208 and rotates with the rotating bushing 207. The lifting rotating block is slidably connected to the outside of the rotating shaft 1091 via a spline. 2081, the lifting rotating block 2081 can rotate with the rotating shaft 1091. The lifting rotating block 2081 is connected to the upper rotating block 2073 through the first torsion spring 2082. The first torsion spring 2082 is sleeved on the outside of the rotating shaft 1091. The two ends of the first torsion spring 2082 are respectively fixed on the upper rotating block 2073 and the lifting rotating block 2081. The upper rotating block 2073 drives the lifting rotating block 2081 to rotate through the first torsion spring 2082. The corresponding sides of the upper rotating block 2073 and the lifting rotating block 2081 are matching arc surfaces. During the rotation of the lifting rotating block 2081, the upper rotating block 2073 and the rotating bushing 207 can be driven to rotate through the first torsion spring 2082.

[0045] The amount of straw crushed and ground in this device each time is related to the final amount of pulp to be produced. After each crushing, it is necessary to wait for the pulping to be completed and the material to be discharged before proceeding to the next processing. The pulping cylinder 1 has a corresponding water inlet on its side wall, and a one-way valve is installed at the water inlet to quickly add sufficient water during processing. The fibers after screening fall into the water below the pulping cylinder 1. As the rotating sleeve 109 rotates with the rotating cylinder 102, it drives the rotating shaft 1091 to rotate. When the rotating shaft 1091 rotates, it is connected to the lifting block 2081 and the... A torsion spring 2082 drives the upper rotating block 2073 and the rotating bushing 207 to rotate. When the rotating bushing 207 rotates, it drives the agitator 2071 to rotate. When the agitator 2071 rotates, it agitates the fiber and water, allowing the fiber to mix with the water more quickly to form a fiber slurry. When the lifting extrusion plate 202 moves up and down, it drives the fan 206 to move up and down through the rotating sleeve 109. During the up and down movement of the fan 206, it drives the topmost agitator 2071 to rotate around the corresponding rotating bushing 207 through the connecting rod 2061 and the connecting block 2074. The tilt angle between the stirring rod 2071 and the liquid to be stirred is adjusted. The connecting blocks 2074 on the multi-layer stirring rod 2071 are connected by the connecting rotating rod 2072, so that the tilt angles of the stirring rods 2071 at different heights change synchronously. Since the resistance to the rotation of the stirring rod 2071 in the slurry formed by the fiber and water is positively correlated with the fiber thickness, when the fiber is the thinnest, the contact area between the fiber and water is small, and the resistance provided by the fiber during the rotation of the stirring rod 2071 is small. When the fiber is thicker, the contact area between the fiber and water is larger, and the stirring is more efficient. During the rotation of rod 2071, the resistance provided by the fiber is large. When the fiber is at its finest, the stirring rod 2071 remains vertical. When the slurry is formed, the stirring rod 2071 can be subjected to sufficient resistance, so that the stirring rod 2071 and the lifting rotating block 2081 can generate a sufficient speed difference. That is, there is a sufficient speed difference between the upper rotating block 2073 and the lifting rotating block 2081, and the upper rotating block 2073 rotates more slowly. When the lifting rotating block 2081 rotates, it can slide down along the upper rotating block 2073 and press against the pressure sensor on the fixed plate 209.As the fibers coarsen, the agitator 2071 tilts and forms a certain angle with the water. When tilted, the resistance from the water and fibers decreases, ensuring that the initial resistance of the agitator 2071 remains constant. During slurry formation, the tilt angle of the agitator 2071 is directly proportional to the fiber thickness; that is, the coarser the fiber, the larger the tilt angle of the agitator 2071. This ensures that the resistance experienced by the agitator 2071 is the same in slurries formed from fibers of different thicknesses, resulting in a sufficient speed difference between the agitator 2071 and the lifting rotor 2081. A sufficient speed difference exists between the upper rotating block 2073 and the lifting rotating block 2081, causing the upper rotating block 2073 to rotate more slowly. This allows the upper rotating block 2073 to push the lifting rotating block 2081 down and press it against the pressure sensor on the fixed disk 209. The first torsion spring 2082 simultaneously stores force. When all pressure sensors receive sufficient pressure, it indicates that the slurry has been mixed and formed. At this point, the slurry can be removed. After the slurry is removed, the upper rotating block 2073 and the lifting rotating block 2081 return to their original positions under the action of the first torsion spring 2082.

[0046] Example 3: Based on Example 2, such as Figure 1 and Figures 7-9 As shown, the system also includes a crushing mechanism frame 3 for crushing the cleaned straw, a crushing box 301, a control motor 302, a crushing inner cylinder 303, a connecting channel 3031, a crushing rotating rod 304, a rotating crushing blade 3041, and an anti-jamming component. The frame 3 is located on the left side of the pulping cylinder 1. The crushing box 301 is mounted on the frame 3. The control motor 302 is installed inside the frame 3. The crushing rotating rod 304 is rotatably connected inside the crushing box 301. The crushing inner cylinder 303 is fixedly connected inside the crushing box 301. The bottom of the crushing inner cylinder 303 is fixedly connected to the connecting channel 3031. The crushing inner cylinder 303 is connected to the connecting channel 3031. The channel 3031 is connected to the side discharge port of the crushing box 301. The crushing rotor 304 passes through the connecting channel 3031 and extends into the crushing inner cylinder 303. The output shaft of the control motor 302 is connected to the crushing rotor 304. The control motor 302 can drive the crushing rotor 304 to rotate. A rotating crushing blade 3041 is fixed on the crushing rotor 304. During the rotation of the rotating crushing blade 3041, the straw entering the crushing inner cylinder 303 is crushed. The anti-jamming component is installed inside the crushing box 301. When there is too much material in the crushing box 301, the anti-jamming component will close the top inlet of the crushing box 301.

[0047] like Figure 8 and Figure 9As shown, the anti-jamming assembly includes a wedge-shaped rotating block 3042, a second torsion spring 3043, a lifting block 305, a lifting cylinder 3051, a splined shaft 3052, a rotating rod 306, and a sliding baffle 307. The top of the crushing rotating rod 304 is rotatably connected to the wedge-shaped rotating block 3042, and a rotating crushing blade 3041 is fixedly connected to the bottom of the wedge-shaped rotating block 3042. The lifting cylinder 3051 is slidably connected to the crushing box 301, and the bottom of the lifting cylinder 3051 is rotatably connected to the lifting block 3051. The bottom surface of the lifting block 305 matches the top surface of the wedge-shaped rotating block 3042. The splined shaft 3052 is fixedly connected inside the lifting block 305. The top surface of the crushing rotating rod 304 is slidably connected to it. The lifting block 305 and the wedge-shaped rotating block 3042 are connected by a second torsion spring 3043. The two ends of the second torsion spring 3043 are fixed on the lifting block 305 and the wedge-shaped rotating block 3042 respectively. A rotating rod 306 is rotatably connected to the outside of the crushing box 301. A straight slide is opened at both ends of the rotating rod 306. The round rod at the top of the lifting cylinder 3051 passes through the straight slide at the corresponding position of the rotating rod 306 and is slidably connected to it. A sliding baffle 307 is slidably connected inside the crushing box 301. The round rod at the top of the sliding baffle 307 passes through the straight slide at the other end of the rotating rod 306 and is slidably connected to it.

[0048] After cleaning, the straw enters the inner crushing cylinder 303 inside the crushing chamber 301. The control motor 302 drives the rotating crushing blades 3041 to rotate via the crushing rod 304. During the rotation of the rotating crushing blades 3041, the straw entering the inner crushing cylinder 303 is crushed. The crushing rod 304 drives the lifting block 305 to rotate via the splined shaft 3052. Under the action of the second torsion spring 3043, the lifting block 305 pushes the wedge-shaped rotating block 3042 to rotate. When the straw blocks the top inlet of the inner crushing cylinder 303, the straw will restrict the rotating crushing blades 3041 on the wedge-shaped rotating block 3042 and reduce its speed. The speed of the wedge-shaped rotating block 3042 decreases synchronously. Since the lifting block 305 rotates with the crushing rod 304, the speed of the lifting block 305 does not change. At this time, the wedge-shaped rotating block 3042 and the lifting block 3042... A speed difference is formed between the lowering blocks 305, causing the lifting blocks 305 to slide upward along the top arc surface of the wedge-shaped rotating block 3042. The second torsion spring 3043 stores energy and simultaneously pushes the lifting cylinder 3051 upward. When the lifting cylinder 3051 rises, it pushes the sliding baffle 307 downward through the rotating rod 306 to close the entrance of the crushing box 301 and prevent straw from continuing to enter the crushing box 301. When all the straw blocking the top of the crushing inner cylinder 303 has passed, the de-rotating crushing blade 3041 on the wedge-shaped rotating block 3042 is no longer blocked by straw. The second torsion spring 3043 drives the wedge-shaped rotating block 3042 to return to its original position, and the lifting blocks 305 and the lifting cylinder 3051 descend accordingly. The lifting cylinder 3051 drives the sliding baffle 307 to rise through the rotating rod 306 to open the top entrance of the crushing box 301.

[0049] like Figure 10 and Figure 11 As shown, it also includes a screening component for screening and crushing straw. The screening component includes a discharge frame 4, a rotating screen plate 401, and a sliding adjusting rod 402. The discharge frame 4 is fixedly connected to the discharge port on the side of the crushing box 301. The outlet of the connecting channel 3031 corresponds to the inlet of the discharge frame 4. The rotating screen plate 401 is rotatably connected inside the discharge frame 4. The rotating screen plate 401 is divided into upper and lower layers. The sliding adjusting rod 402 is slidably connected to the outside of the pulping cylinder 1. The bottom of the sliding adjusting rod 402 is fixedly connected to the lifting extrusion plate 202. The top of the sliding adjusting rod 402 passes through the discharge frame 4 and is slidably connected to the rotating screen plate 401. The bottom outlet of the discharge frame 4 corresponds to the top inlet of the pulping cylinder 1.

[0050] The crushed straw falls through the connecting channel 3031 onto the rotating screen plate 401 inside the discharge frame 4. As the straw rolls along the rotating screen plate 401, it is screened. The qualified crushed straw falls to the lower layer of the rotating screen plate 401 and finally enters the pulping cylinder 1 from the bottom outlet of the discharge frame 4. The unqualified straw slides down from the top of the rotating screen plate 401 and falls outwards from the side outlet of the discharge frame 4. Furthermore, when adjusting the height of the lifting extrusion plate 202, the fibers produced become finer as the plate rises, increasing the grinding time. The sliding adjustment rod 402 causes the rotating screen plate 401 to swing upwards, reducing its tilt angle and thus lowering the grinding efficiency. The speed at which the crushed straw rolls along the rotating screen plate 401 allows it to enter the pulping cylinder 1 more slowly, giving the inner grinding block 106 and the outer grinding cylinder 101 sufficient time to grind the straw into finer fibers. This prevents the straw from accumulating in the pulping cylinder 1. When the lifting and pressing plate 202 descends, the ground fibers become coarser, and the grinding time becomes shorter. This causes the rotating screen plate 401 to swing downwards via the sliding adjusting rod 402, increasing the tilt angle of the rotating screen plate 401. This, in turn, increases the speed at which the crushed straw rolls along the rotating screen plate 401, allowing it to enter the pulping cylinder 1 more quickly. This ensures that the speed at which the straw falls is equal to the grinding speed.
