[0027] See also Figure 1-Figure 6As shown, the present invention is a waste recycling device for the production of degradable straws, comprising a recycling box 1, a feed inlet 11 is provided on the top surface of the recycling box 1, symmetrical crushing rollers 2 are rotatably installed in the recycling box 1, and each crushing roller 2 is provided with a crushing knife 21, a straw discharge mechanism 3 is provided at the upper feed inlet 11 of the recycling box 1, and the straw discharge mechanism 3 is used to vertically discharge the straws put into the feed inlet 11, a screening cleaning mechanism 4 is installed at the bottom of the recycling box 1, and the screening cleaning mechanism 4 is used to clean the crushed straws, and a hot melt recovery mechanism 5 is provided at the bottom of the recycling box 1, and the hot melt recovery mechanism 5 is used to hot melt recovery of the cleaned crushed straws;

[0028] In the scheme designed by the present invention, a straw discharge mechanism 3 is arranged above the feed port 11 of the recycling box 1. When the waste straws need to be recycled and crushed, the operator needs to put the straws into the straw discharge mechanism 3 first, so that the straws to be crushed and recycled can be vertically arranged in the straw discharge mechanism 3 first, and then a plurality of vertically arranged straws will synchronously enter between the two crushing rollers 2, so that the crushing knives 21 on the crushing rollers 2 rotating in opposite directions can synchronously crush the plurality of arranged and falling straws, which will not only prevent the straws to be crushed from being blocked above the feed port 11 and the crushing rollers 2, but also can The used straws are evenly crushed, and the evenly crushed straw particles will fall into the screening and cleaning mechanism 4 at the bottom of the recycling box 1, so that the evenly crushed straw particles can be cleaned, and the cleaned straw particles will enter the hot melt recovery mechanism 5, and the hot melt recovery mechanism 5 will first dry the cleaned straw particles, and then melt them for recovery, so that the crushed straw particles can be directly cleaned, melted and recovered in the recycling box 1, so that there is no need to take them out separately, then clean them, and then hot-melt recover them, which can further improve the recycling efficiency of the waste recycling device of the present invention for used degradable straws.

[0029] As an embodiment of the present invention, the straw discharge mechanism 3 includes a discharge box 31, a collecting hopper 32, a blocking bar 33, a supporting insert 34 and an inspection door 35. The discharge box 31 which is connected from top to bottom is vertically fixed at the feed port 11, and the width of the discharge box 31 is the same as the width of the feed port 11. The upper end of the discharge box 31 is fixed with a collecting hopper 32. At least two blocking bars 33 are installed in the discharge box 31, and at least two rows of several straw through holes 331 are evenly spaced on each blocking bar 33. An inspection cavity 311 is opened at the right side wall of the discharge box 31 corresponding to the blocking bar 33. Support slide grooves 312 are opened at the front and rear side walls of the discharge box 31 corresponding to the inspection cavity 311. The front and rear end surfaces of the blocking bar 33 are slidably inserted into the supporting slide grooves 312 through the supporting insert 34. The inspection cavity 311 is detachably installed with an inspection door 35.

[0030] In the scheme designed by the present invention, when the waste straws need to be crushed and recycled, the straws are first placed vertically into the collecting hopper 32, and the straws placed in the collecting hopper 32 will vertically enter the discharge box 31. Since at least two rows of straw perforations 331 are evenly and equidistantly opened on the retaining bar 33, the straws entering the discharge box 31 will be vertically inserted into the straw perforations 331 in sequence, so that the straws can be arranged vertically in multiple groups in the discharge box 31, and then the multiple straws arranged vertically will drop to the crusher through the feed port 11 due to gravity. The crushing rollers 2 are arranged between the crushing blades 21, so that the crushing blades 21 can crush the descending multiple vertical straws. At the same time, because the multiple straws descend in the straw perforations 331, when the rotating crushing blades 21 crush the newly descended straws, the top ends of the multiple straws will not shake or swing in the feed port 11, thereby preventing the straws from splashing or being blocked in the feed port 11 when they are randomly put into the feed port 11 for crushing. The distance between the stopper bars 33 is smaller than the length of the straws, so that when the descending multiple straws are located in the straw through-holes 331 opened on the lower stopper bar 33, the straws in the collecting hopper 32 will continue to enter the straw through-holes 331 opened on the upper discharge bar. When the multiple straws located below are completely entered into the recovery box 1, the straws arranged above will continue to pass through the straw through-holes 331 below and move downward, so that the straws in the collecting hopper 32 can evenly and quickly fall into the discharge box 31 for vertical arrangement. The processing can be carried out without affecting the normal crushing processing of the straws. When the inspection door 35 made of transparent glass is opened, the retaining strip 33 can be taken out from the discharge box 31 for replacement or repair. At the same time, large impurities that fall on the retaining strip 33 can be cleaned to prevent clogging of the straw perforation 331. The cleaned or replaced retaining strip 33 is then inserted into the supporting slide groove 312 through the supporting insert strip 34 to support and fix the retaining strip 33. The inspection door 35 is then installed in the inspection cavity 311 to achieve fixed installation of the retaining strip 33.

[0031] As an embodiment of the present invention, the suction pipe discharge mechanism 3 further includes a threaded column 36, a gasket 37, a locking nut 38 and a dust suction pipe 39. The support slide groove 312 is fixed with a threaded column 36, and the threaded column 36 extends through the support insert 34. The threaded column 36 is sleeved with a gasket 37, and the gasket 37 is attached to the outer side of the inspection door 35. The threaded column 36 is threadedly connected with a locking nut 38, and the locking nut 38 is located on the outer side of the gasket 37. A plurality of dust suction pipes 39 are installed on the inspection door 35, and the pipe openings of the plurality of dust suction pipes 39 extend into the discharge box 31 and are flush with the blocking strip 33.

[0032] In the design of the present invention, when it is necessary to disassemble the stopper strip 33, the locking nut 38 and the gasket 37 are first removed, and then the inspection door 35 is removed from the inspection chamber 311, and then the support strips 34 at both ends of the stopper strip 33 are pulled out from the support slide groove 312, so as to facilitate the disassembly, maintenance or replacement of the stopper strip 33; when it is necessary to install the stopper strip 33, the support strip 34 is aligned with the support slide groove 312, and the stopper strip 33 is pushed so that the support strips 34 at both ends are slidably inserted into The inspection door 35 is then installed in the inspection chamber 311 through the support groove 312, and the gasket 37 is then sleeved onto the threaded column 36. At this time, the gasket 37 will fit the outer side of the inspection door 35, and then the locking nut 38 is threadedly connected to the threaded column 36, which can not only fix the retaining strip 33, but also fix the inspection door 35 in the inspection chamber 311. The dust suction pipe 39 can suck and discharge small particles or dust impurities that fall onto the upper surface of the retaining strip 33 to prevent the suction pipe perforation 331 from being blocked.

[0033] As an embodiment of the present invention, the screening cleaning mechanism 4 includes a cleaning box 41, a screen 42, a support spring 43, a push cylinder 44, a guide plate 45, a water injection pipe 46 and a drain pipe 47. The cleaning box 41 is fixedly installed inside the bottom of the recovery box 1, and the upper box opening of the cleaning box 41 is aligned with the symmetrical crushing rollers 2. The heights of the left and right box walls of the cleaning box 41 are lower than the heights of the front and rear box walls. A screen 42 made of elastic material is slidably arranged in the cleaning box 41, and the outer walls around the screen 42 are in contact with the inner wall of the cleaning box 41. The lower surfaces of the front and rear side walls of the screen 42 are Three support springs 43 are fixed at equal intervals, three push cylinders 44 are vertically fixed to the bottom of the cleaning box 41, and the upper end surfaces of the piston rods of the three push cylinders 44 are respectively connected to the three support springs 43, and the left and right side walls of the cleaning box 41 are obliquely installed with guide plates 45, and the other end of the guide plate 45 extends into the hot melt recovery mechanism 5, and the front and rear side walls of the recovery box 1 are respectively fixed with a water injection pipe 46 and a drainage pipe 47, and the pipe openings of the water injection pipe 46 and the drainage pipe 47 are connected to the cleaning box 41, and the bottom of the recovery box 1 is a sloped surface toward the pipe opening of the drainage pipe 47;

[0034] In the scheme designed by the present invention, after the crushing blade 21 on the crushing roller 2 evenly crushes the multiple vertically arranged straws into granular materials, the straw particles will fall to the top of the screen 42 in the cleaning box 41 below. When a certain amount of straw particles fall into the cleaning box 41, the crushing roller 2 can be stopped, and then the cleaning solution is injected into the cleaning box 41 through the water injection pipe 46, so that the cleaning solution is filled into the cleaning box 41, and then the piston rod of the push cylinder 44 is controlled to extend or retract, so that it drives the screen 42 to move back and forth up and down in the cleaning box 41, which can drive the straw particles on the screen 42 to reciprocate up and down in the cleaning box 41 for cleaning, thereby increasing the cleaning efficiency. The cleaning efficiency of the straw particles can be improved quickly, and at the same time, the straw particles can be separated from the impurities or soil after cleaning, so that the impurities or soil after cleaning will fall to the bottom of the cleaning box 41 and gather. When the straw particles on the screen 42 are cleaned, the piston rod of the push cylinder 44 is controlled to extend to push the screen 42 to rise above the liquid surface of the cleaning box 41 for water control. At the same time, when the screen 42 rises above the liquid surface, the piston rod of the push cylinder 44 can be controlled to extend or retract, so that the screen 42 can drive the cleaned straw particles to shake and control water, thereby speeding up the water control efficiency of the cleaned straw particles, and then continue to drive the push cylinder 44. The piston rod extends, causing the screen 42 to continue to rise and be flush with the left and right side walls of the cleaning box 41 or slightly higher than the left and right box walls of the cleaning box 41, and then the piston rod of the middle pushing cylinder 44 is controlled to continue to extend, while the pushing cylinders 44 at the four corners do not work, and then the piston rod of the middle pushing cylinder 44 extends to push the middle part of the elastic material screen 42 to bulge upward and deform, thereby facilitating the introduction of the cleaned straw particles on the screen 42 to the guide plates 45 on the left and right sides of the cleaning box 41, and then enter the hot melt recovery mechanism 5 along the guide plates 45. When all the straw particles on the screen 42 are discharged, the pushing cylinder 44 is controlled to work, so that the screen 42 returns to its original position. The sieve 42 is in a flat state and descends into the cleaning box 41 to continue sieving and cleaning the crushed and fallen straw particles, while automatically guiding the cleaned straw particles to the guide plates 45 on both sides. The operator can regularly open the drain pipe 47 to discharge and replace the cleaning waste water in the cleaning box 41; the piston rod end face of the push cylinder 44 is in a soft connection state with the sieve 42 through the support spring 43, which can increase the shaking amplitude of the sieve 42 in or above the liquid surface of the cleaning box 41, thereby improving the cleaning effect and water control effect on the straw particles, and at the same time making it convenient for the middle part of the sieve 42 to bulge and deform above the cleaning box 41 to accelerate the discharge of the straw particles.

[0035] As an embodiment of the present invention, a plurality of inclined guide plates 6 are installed below the symmetrical crushing roller 2, and the inclined guide plates 6 are installed in the recovery box 1, and a blocking door 61 that can be opened automatically is installed at the discharge port below the two inclined guide plates 6, and the discharge port is located directly above the cleaning box 41; in the scheme designed by the present invention, the straw particles crushed by the crushing roller 2 will fall onto the inclined guide plates 6, and then the blocking door 61 is opened, so that the straw particles can accurately fall into the cleaning box 41 through the discharge port, and when a certain amount of straw particles falls into the cleaning box 41, the straw particles can be removed from the cleaning box 41. After the straw particles are collected, the sealing door 61 is closed so that the discharge port is in a closed state. The crushing roller 2 then works so that the crushed straw particles are gathered in the collecting bucket 54 formed by the two inclined guide plates 6. The crushing roller 2 does not stop crushing the waste straws, and the cleaning box 41 can continue to work to clean the straw particles, thereby further accelerating the crushing and recycling efficiency of the waste degradable straws by the recycling device, and the height at which the inclined guide plate 6 is installed will not interfere with the normal rising and moving of the screen 42 in the cleaning box 41.

[0036] As an embodiment of the present invention, the hot melt recovery mechanism 5 includes a drying box 51, a sealing door 52, a hot melt box 53, a collecting bucket 54 and a pull handle 55. The two drying boxes 51 are respectively fixed below the left and right outer walls of the recovery box 1, and the two drying boxes 51 are provided with a feeding cavity 511 on the side walls that are in contact with the recovery box 1, and a guide plate 45 is obliquely inserted into the feeding cavity 511. A sealing door 52 is rotatably installed at the bottom discharge cavity of the drying box 51, and the sealing door 52 is located in the hot melt box 53. The hot melt box 53 is fixed at the bottom of the recovery box 1, and a heating wire is provided in the hot melt bin of the hot melt box 53. A collecting bucket 54 is slidably inserted into the hot melt bin of the hot melt box 53, and a pull handle 55 is fixed on the outer end surface of the collecting bucket 54. The bucket mouth of the collecting bucket 54 corresponds to the discharge cavity of the symmetrical drying box 51.

[0037] In the scheme designed in the present invention, when the cleaned straw particles fall onto the guide plate 45 and then enter the drying box 51 through the feed cavity 511, part of the heat generated in the hot melt box 53 will enter the drying box 51, which can accelerate the drying effect of the drying box 51 on the cleaned straw particles and prevent the cleaned straw particles from being directly put into the hot melt box 53 for hot melting without being dried, which may easily cause water mist or other dangerous objects to be generated in the hot melt box 53, thereby affecting the efficiency and safety of hot melt recovery of the crushed straw particles by the hot melt box 53. After the box 51 has finished drying the straw particles inside at a fixed time, the sealed door 52 at the bottom of the drying box 51 is turned to open, and the sealed door 52 is tilted toward the collecting bucket 54. Then, the dried straw particles in the drying box 51 will automatically fall into the collecting bucket 54. Then, the sealed door 52 is closed to allow the heating wire in the hot melt box 53 to work and perform hot melt treatment on the straw particles collected in the collecting bucket 54. After the hot melt is completed and the collecting bucket 54 has cooled down, the operator pulls the handle 55 to take the collecting bucket 54 out of the hot melt box 53 to facilitate hot melt recovery of the crushed straw particles.

[0038] As an embodiment of the present invention, one end face of the symmetrical guide plate 45 is elastically connected to the left and right side walls of the cleaning box 41, the lower surface of the other end face of the guide plate 45 is connected to the elastic insulation film 48, and the elastic insulation film 48 is connected to the lower cavity wall of the feed cavity 511 opened on the side wall surface of the recovery box 1, and at least two rapping cylinders 49 are fixed to the bottom of the recovery box 1, and the top end surfaces of the piston rods of at least two rapping cylinders 49 are softly connected to the lower surface of the guide plate 45;

[0039] In the scheme designed by the present invention, when the convex and deformed screen 42 guides the water-controlled straw particles onto the guide plates 45 on both sides, the piston rod of the vibrating cylinder 49 can be controlled to extend and retract frequently and slowly, so that it drives the elastically connected guide plates 45 to produce tilted shaking, thereby facilitating the guide plates 45 to quickly guide the straw particles into the drying box 51 for drying. When all the straw particles on the guide plates 45 enter the drying box 51, the piston rod of the vibrating cylinder 49 is controlled to continue to extend, so that it drives the end of the guide plate 45 that is in contact with the lower cavity wall of the feed chamber 511 to swing upward to fit the upper cavity wall of the feed chamber 511. At this time, the elastic insulation film 48 will be stretched, so that the elastic insulation film 48 can seal the feed chamber 511, thereby facilitating the separation of the drying box 51 and the recovery box 1, preventing the heat in the drying box 51 from entering the recovery box 1, thereby accelerating the drying efficiency of the drying box 51 for the straw particles. When the drying box 51 has finished drying the straw particles and discharged them, and then the straw particles on the screen 42 need to enter the drying box 51, the piston rod of the vibration cylinder 49 is controlled to contract, so that it drives the guide plate 45 to be tilted downward, and the elastic insulation film 48 will be compressed, thereby facilitating the guide plate 45 to continue shaking and guiding the cleaned straw particles.

[0040] As an embodiment of the present invention, a plurality of hot air holes 512 are provided on the outer side of the drying box 51 near the hot melt box 53 along its length direction, and a filter net is installed in the hot air holes 512; in the scheme designed by the present invention, the heat generated by the hot melt box 53 during operation will enter the drying box 51 through the plurality of hot air holes 512, so that the heat will dry the straw particles entering the drying box 51, and the filter net will block the hot air holes 512 to prevent the straw particles from directly entering the hot melt box 53 through the hot air holes 512 without being dried.

[0041] Working principle:

[0042] When the waste straws need to be crushed and recycled, the straws are first placed vertically into the collecting hopper 32, and the straws placed in the collecting hopper 32 will vertically enter the discharge box 31. Since at least two rows of straw perforations 331 are evenly and equidistantly provided on the retaining bar 33, the straws entering the discharge box 31 will be vertically inserted into the straw perforations 331 in sequence, so that the straws can be arranged vertically in multiple groups in the discharge box 31, and then the multiple vertically arranged straws will drop through the feed port 11 to between the crushing rollers 2 due to gravity, so that the crushed straws can be crushed and recycled. The crushing blade 21 can crush the descending multiple vertical straws. When the crushing blade 21 on the crushing roller 2 evenly crushes the multiple vertically arranged straws into granular materials, the straw particles will fall to the top of the screen 42 in the cleaning box 41 below. When a certain amount of straw particles falls into the cleaning box 41, the crushing roller 2 can be stopped, and then the cleaning solution is injected into the cleaning box 41 through the water injection pipe 46, so that the cleaning solution is filled into the cleaning box 41, and then the piston rod of the push cylinder 44 is controlled to extend or retract. The screen 42 is driven to move reciprocatingly up and down in the cleaning box 41, and the straw particles on the screen 42 can be driven to move reciprocatingly up and down in the cleaning box 41 for cleaning. When the straw particles on the screen 42 are cleaned, the piston rod of the push cylinder 44 is controlled to extend, so that the screen 42 is pushed up to the liquid level of the cleaning box 41 for water control. At the same time, when the screen 42 rises above the liquid level, the piston rod of the push cylinder 44 can be controlled to extend or retract, so that the screen 42 can drive the cleaned straw particles to perform shaking control. Water, and then continue to drive the piston rod of the push cylinder 44 to extend, so that the screen 42 continues to rise and is flush with the left and right side walls of the cleaning box 41 or slightly higher than the left and right box walls of the cleaning box 41, and then the piston rod of the middle push cylinder 44 is controlled to continue to extend, while the push cylinders 44 at the four corners do not work, and then the extension of the piston rod of the middle push cylinder 44 will push the middle part of the elastic material screen 42 to bulge upward and deform, so as to facilitate the introduction of the cleaned straw particles on the screen 42 to the guide plates 45 on the left and right sides of the cleaning box 41;

[0043] When the cleaned straw particles fall onto the guide plate 45 and then enter the drying box 51 through the feed chamber 511, part of the heat generated in the hot melt box 53 will enter the drying box 51 for drying. When the drying box 51 has completed the timed drying of the straw particles inside, the sealing door 52 at the bottom of the drying box 51 is turned to open, and the sealing door 52 is tilted toward the collecting bucket 54. Then, the dried straw particles in the drying box 51 will automatically fall into the collecting bucket 54. Then, the sealing door 52 is closed to allow the heating wire in the hot melt box 53 to work and hot-melt the straw particles collected in the collecting bucket 54. After the hot melting is completed and the collecting bucket 54 has cooled, the operator pulls the handle 55 to take the collecting bucket 54 out of the hot melt box 53 to facilitate hot-melt recovery of the crushed straw particles.
