The stirring assembly 9 is arranged in the cleaning box 8, and the first crushing assembly 4 is connected to the stirring assembly 9 through the first transmission assembly 6, and the stirring assembly 9 is connected to the second crushing assembly 5 through the second transmission assembly 7. Double crushing is performed by the first crushing assembly 4 and the second crushing assembly 5, and the crushing effect is good. Crushing and cleaning are integrated into one equipment setting, which reduces the floor space, does not require manual transfer and handling, reduces labor intensity, and improves production efficiency. Through the cooperation of the first transmission assembly 6 and the second transmission assembly 7, only one driving source is needed to realize double crushing and stirring and cleaning operations, and each processing step is cleverly linked to reduce manufacturing and use costs. When the crushed waste needs to be cleaned, the first valve 3 is opened, the waste enters the cleaning box 8, cleaning liquid is added to the cleaning box 8, and the waste and the cleaning liquid are stirred by the stirring component 9 to achieve stirring and cleaning operations.

[0041] The first crushing assembly 4 includes a first mounting frame 41, a motor 42, a first bearing seat 43, a spur gear 44, and a crushing roller 45.

The front and rear crushing rollers 45 cooperate with each other. Each crushing roller 45 is fixed with a spur gear 44. The front and rear spur gears 44 are meshed, and the right end of the crushing roller 45 on the front side is connected to the motor 42. During the first crushing, the motor 42 is started to drive the crushing roller 45 on the front side to rotate, and the crushing roller 45 on the rear side is driven to rotate through the spur gear 44. The waste is initially crushed by the rotation of the front and rear crushing rollers 45.

[0042] The second crushing assembly 5 includes a second mounting frame 51, a second bearing seat 52, a first rotating shaft 53, a crushing knife 54, and a fixed knife 55. The second mounting frame 51 is fixed inside the crushing box 2 and is located below the crushing roller 45. The cross section of the second mounting frame 51 is triangular. The second bearing seat 52 is fixed at the center of the bottom of the second mounting frame 51. The top of the first rotating shaft 53 is inserted into the second bearing seat 52. A plurality of crushing knives 54 are fixed at the lower part of the first rotating shaft 53. A plurality of fixed knives 55 are fixed on the inner side wall of the crushing box 2. The fixed knives 55 and the crushing knives 54 are staggered. After the waste material is initially crushed, it falls. Under the action of the second transmission assembly 7, the first rotating shaft 53 rotates, driving the crushing knife 54 to rotate, and cooperates with the fixed knife 55 staggered therewith to perform secondary crushing on the waste material. The waste material is double-crushed by using different crushing methods of the crushing roller 45 and the crushing knife 54, and the crushing effect is good. The setting of the second mounting frame 51 with a triangular cross section prevents the fallen waste material from accumulating on the second mounting frame 51.

[0043] The stirring assembly 9 includes a third bearing seat 91, a second rotating shaft 92, and a hollow stirring frame 93. The third bearing seat 91 is fixed to the center of the top of the cleaning box 8 and the frame 1. The lower part of the second rotating shaft 92 passes through the third bearing seat 91 and the top wall of the cleaning box 8, and extends to the inside of the cleaning box 8 where the hollow stirring frame 93 is fixed. During the stirring operation, the second rotating shaft 92 is driven to rotate by the first transmission assembly 6, so that the hollow stirring frame 93 rotates to perform the stirring operation.

[0044] Among them, the first transmission assembly 6 includes a first bevel gear 61 and a second bevel gear 62. The first bevel gear 61 is fixed to the right side of the crushing roller 45 located on the front side, and the second bevel gear 62 is fixed to the upper part of the second rotating shaft 92. The first bevel gear 61 is meshed with the second bevel gear 62. When the crushing roller 45 located on the front side rotates, it drives the first bevel gear 61 to rotate, so that the second bevel gear 62 rotates, and drives the second rotating shaft 92 to rotate, and performs stirring and cleaning operations. In this way, stirring and cleaning operations are performed while performing the initial crushing, which greatly improves efficiency. Specifically, when the waste after the first round of crushing enters the cleaning box 8, the first valve 3 is closed, and the second round of waste to be processed is continuously poured into the crushing box 2, and the first crushing treatment is performed through the first crushing assembly 4. At the same time, the waste after the first round of crushing is stirred and cleaned in the cleaning box 8, which greatly improves efficiency.

[0045] Among them, the second transmission assembly 7 includes a driving wheel 71, a driven wheel 72, and a transmission belt 73. The driving wheel 71 is fixed to the upper part of the second rotating shaft 92, and the driven wheel 72 is fixed to the upper part of the first rotating shaft 53. The driving wheel 71 and the driven wheel 72 are connected by the transmission belt 73. The second rotating shaft 92 rotates, driving the driving wheel 71 to rotate, and the driven wheel 72 is driven by the transmission belt 73 to rotate, so that the first rotating shaft 53 rotates, and the crushing knife 54 rotates to perform secondary crushing. In this way, the transmission between the crushing roller 45 and the second rotating shaft 92 is realized by the cooperation of the first bevel gear 61 and the second bevel gear 62, and then the transmission between the second rotating shaft 92 and the second rotating shaft 92 is combined with the driving wheel 71, the driven wheel 72, and the transmission belt 73. Through one motor 42, three different operations can be realized at different positions, which not only cleverly links each processing step, but also makes the structure more compact and reduces space occupation.

[0046] The stirring assembly 9 further includes a third bevel gear 94, a fourth bevel gear 95, a sealing box 96, a fourth bearing seat 97, a third rotating shaft 98, and a stirring plate 99. The sealing box 96 is fixed to the bottom of the cleaning box 8. The bottom end of the second rotating shaft 92 passes through the top wall of the sealing box 96 and extends to the sealing box 96, where the third bevel gear 94 is fixed. The fourth bearing seat 97 is fixed to the left and right side walls of the sealing box 96. The inner end of the third rotating shaft 98 is fixed with a fourth bevel gear 95, which meshes with the third bevel gear 94. The outer end of the third rotating shaft 98 passes through the fourth bearing seat 97 and the side wall of the sealing box 96, and extends to the outside of the sealing box 96, where a plurality of stirring plates 99 are fixed. The stirring plates 99 are located below the hollow stirring frame 93. The second rotating shaft 92 rotates, driving the third bevel gear 94 to rotate, causing the fourth bevel gear 95 to rotate, driving the third rotating shaft 98 to rotate, and causing the stirring plates 99 to rotate. The rotation direction of the stirring plates 99 is perpendicular to the rotation direction of the hollow stirring frame. The second rotating shaft 92 drives the hollow stirring frame to stir and clean while also driving the stirring plate 99 to stir and clean. The waste is cleaned by using two different rotation directions, upper and lower, and different stirring and cleaning forms, which has a better cleaning effect, makes the cleaning more comprehensive and more efficient. The third bevel gear 94 and the fourth bevel gear 95 cooperate to realize stirring redirection and one-belt-two stirring, and cooperate with the hollow stirring frame to realize stirring and cleaning without dead angles.

[0047] The machine frame 1 further comprises a cam 10, a push plate 11, a push rod 12, a cylinder body 13, a piston 14, a spring 15, an air inlet pipe 16, an air outlet pipe 17, a first one-way valve 18, and a second one-way valve 19. The cam 10 is fixed to the upper part of the second rotating shaft 92, the cylinder body 13 is fixed to the upper part of the frame 1, the piston 14 is slidably connected in the cylinder body 13, the push rod 12 is fixed to the left end of the piston 14, the left end of the push rod 12 extends out of the cylinder body 13 and is fixed with a push plate 11, the push plate 11 contacts the cam 10, the right side wall of the push plate 11 is fixed with a spring 15, and the right side of the spring 15 The end is fixedly connected to the left wall of the piston 14, the right side of the top wall of the cylinder body 13 is fixedly connected to the air inlet pipe 16, and the first one-way valve 18 is arranged in the air inlet pipe 16. The right side wall of the cylinder body 13 is fixedly connected to the air outlet pipe 17, and the second one-way valve 19 is arranged in the air outlet pipe 17. The interior of the second rotating shaft 92 has an air flow channel 921, and the air outlet end of the air outlet pipe 17 is inserted into the air flow channel 921 from the top of the second rotating shaft 92. The hollow stirring frame 93 has a plurality of air holes 931, and the air holes 931 are connected to the air flow channel 921. The inner diameter of the air flow channel 921 decreases from top to bottom. The second rotating shaft 92 rotates, driving the cam 10 to rotate, and cooperates with the spring 15 to make the piston 14 move left and right, continuously pumping air into the air flow channel 921, and the air flow is discharged through the air holes 931. The blown air flow can accelerate the movement of the waste particles in the cleaning liquid, making the interaction between the particles and between the particles and the cleaning liquid more frequent and intense. This enhanced stirring effect helps to disperse the cleaning liquid more evenly and improve the cleaning efficiency. The effect of airflow can promote the cleaning liquid to better penetrate into the gaps and surfaces of the waste particles, so as to contact the waste particles more fully. This contact is a key link in the cleaning process, because only when the cleaning liquid is in full contact with the waste particles can the dirt and impurities attached to the surface of the particles be effectively removed. The impact force generated by the airflow during the stirring process helps to loosen and peel off the dirt on the surface of the waste particles. At the same time, the airflow can also promote the chemical reaction between the chemical cleaning agent (such as surfactant, alkali, acid, etc.) in the cleaning liquid and the dirt, thereby accelerating the dissolution and dispersion of the dirt. Through the setting of the first one-way valve 18, the gas can only enter the cylinder body 13 through the air inlet pipe 16, and will not be discharged from the cylinder body 13 to the air inlet pipe 16. Through the setting of the second one-way valve 19, the gas can only be discharged from the cylinder body 13 to the air outlet pipe 17, and will not flow back from the air outlet pipe 17 to the cylinder body 13. The setting of the airflow channel 921 with a decreasing inner diameter from top to bottom makes the blown airflow flow rate faster and the airflow cleaning effect better.

[0048] Among them, the hollow stirring frame 93 includes a plurality of hollow transverse plates 932 and a hollow vertical plate 933, wherein the plurality of hollow transverse plates 932 are arranged at intervals along the axial direction of the second rotating shaft 92, the hollow vertical plate 933 is fixedly connected to the outer end of the hollow transverse plate 932, the hollow transverse plate 932 is connected to the air flow channel 921, the upper and lower side walls of the hollow transverse plate 932 are provided with a plurality of mutually displaced pores 931, and the left and right side walls of the hollow vertical plate 933 are provided with a plurality of relatively arranged pores 931. The design of the hollow transverse plate 932 and the hollow vertical plate increases the contact area of ​​the cleaning liquid and improves the cleaning efficiency. And combined with the setting of the pores 931, the air flow can be more evenly distributed in the cleaning box 8. The mutually displaced pores 931 are set to further ensure the uniformity and diffusivity of the air flow and reduce the dead angle of the air flow. The design of the hollow stirring frame 93 optimizes the air flow channel 921 and distribution and reduces unnecessary energy consumption.

[0049] Among them, the bottom wall of the cleaning box 8 is fixedly connected with a drain pipe 20, a filter screen 21 is fixedly provided in the upper part of the drain pipe 20, and a second valve 22 is provided in the drain pipe 20. A discharge pipe 23 is fixedly connected to the lower right side wall of the cleaning box 8, and a third valve 24 is provided in the discharge pipe 23. A first heating wire 25 is provided inside the end of the outlet pipe 17 close to the air flow channel 921, and a second heating wire 26 is provided inside the stirring plate 99. The first heating wire 25 and the second heating wire 26 are provided to achieve a drying effect, and combined with double crushing and stirring and cleaning, crushing, cleaning, and drying are integrated into one device, which greatly reduces space occupation and labor intensity. After the waste is cleaned, the second valve 22 is opened, and the cleaning liquid is discharged through the drain pipe 20. The waste is blocked by the filter 21 in the cleaning box 8. After the cleaning liquid is discharged, the second valve 22 is closed, and the hollow stirring frame and the stirring plate 99 continue to rotate, turning the waste, and continue to supply air. The airflow is heated by the first heating wire 25 to form a hot air flow, which is discharged through the air hole 931 and blown to the waste for airflow drying. At the same time, the second heating wire 26 heats the stirring plate 99, and the waste is contact-dried by the stirring plate 99. With two different drying forms, combined with the online turning of the waste, the drying efficiency is greatly improved, making the drying more comprehensive. In addition, a set of equipment is used for cleaning and drying. When drying is required, only the first heating wire 25 and the second heating wire 26 need to be opened, which greatly reduces space occupancy and reduces costs. After drying, the third valve 24 is opened, and the dried waste is discharged through the discharge pipe 23.
