Detailed implementation manners

[0035] Example 1

[0036] As Figures 1 - 8 shown, a solid waste crushing and recycling device includes a crushing box 1. A box cover 2 is installed on the top of the crushing box 1 through screws. A feeding cylinder 3 is welded in the middle of the top end of the box cover 2. One end of the outside of the crushing box 1 is fixedly connected with a crushing motor 4. The crushing motor 4 is drivingly connected with a crushing roller 5 through two gears;

[0037] A crushing auxiliary part 6 is installed inside the crushing box 1. The crushing auxiliary part 6 includes a driving motor 601, a uniform feeding part 602, a screening and reflux part 603, a guide plate 604, a driving motor 605, a water tank 606, a crushing part 607, a dust reduction part 608, a pushing part 609 and a discharge plate 610;

[0038] A driving motor 601 is fixedly connected to one end of the outside of the crushing box 1. A uniform feeding part 602 is arranged at the top end inside the crushing box 1. A screening and reflux part 603 is arranged at the bottom of the crushing roller 5 inside the crushing box 1. Guide plates 604 are installed at both ends of the top inside the crushing box 1 through screws. One end of the feeding cylinder 3 is fixedly connected with a driving motor 605. A water tank 606 is placed at one end of the outside of the crushing box 1. A crushing part 607 is arranged inside the feeding cylinder 3. A dust reduction part 608 is arranged at the end of the water tank 606. A discharge plate 610 is installed at the bottom of the screening and reflux part 603 inside the crushing box 1 through screws. A pushing part 609 is arranged at one end of the outside of the crushing box 1 close to the discharge plate 610. A water inlet hole (not shown in the figure) is opened at the end of the water tank 606.

[0039] Turn on the driving motor 601, the crushing motor 4 and the driving motor 605, and add solid waste into the feeding cylinder 3. The solid waste enters the inside of the crushing box 1 through the feeding cylinder 3. At this time, the solid waste is preliminarily crushed by the crushing part 607 to facilitate the crushing of the solid waste. During this process, the dust reduction part 608 runs synchronously for dust reduction to avoid the problem of dust splashing during the crushing process and affecting the surrounding environment. Subsequently, the solid waste enters the inside of the crushing box 1 and is crushed by the crushing roller 5. The crushed solid waste falls onto the top of the screening and reflux part 603. The solid waste is screened. The unqualified solid waste is transported to the top of the crushing roller 5 again for crushing to improve the crushing effect. The qualified solid waste falls onto the top of the discharge plate 610 and is discharged along the discharge plate 610. During the discharging process, the pushing part 609 runs to push the solid waste back and forth to both ends of the crushing box 1 to avoid the problem that the solid waste accumulates at one end of the crushing box 1 and makes it inconvenient to discharge the subsequent solid waste.

[0040] The uniform feeding part 602 includes a semi-gear 6021, a driving gear 6022, a connecting driving part 6023 and a rotating plate 6024;

[0041] The output shaft of the drive motor 601 is fixedly connected with a half gear 6021. One end of the half gear 6021 is meshed and connected with a driving gear 6022. One end of the driving gear 6022 is provided with a connecting driving member 6023, and the end of the connecting driving member 6023 is fixedly connected with a rotating plate 6024.

[0042] The connecting driving member 6023 includes two driving pulleys, a driving belt and two driving gears. One end of the crushing box 1 is rotatably connected with two driving pulleys. The two driving pulleys are connected by a driving belt. One end of a driving pulley is fixedly connected with a driving gear. The two driving gears are meshed and connected. The other driving gear is rotatably connected to one end of the crushing box 1. The two rotating plates 6024 are respectively fixedly connected with the other driving pulley and the other driving gear, so that the rotating plate 6024 can be rotated, thereby opening and closing the bottom of the feeding cylinder 3.

[0043] The rotation of the output shaft of the drive motor 601 drives the half gear 6021. Through the meshing connection between the half gear 6021 and the driving gear 6022, the driving gear 6022 is driven to rotate. Through the connection of the connecting driving member 6023, the rotating plate 6024 is rotated to close the bottom of the feeding cylinder 3. When the half gear 6021 is not meshed with the driving gear 6022, at this time, the weight of the solid waste at the top of the discharge plate 610 pushes the discharge plate 610 to rotate, so that the bottom of the feeding cylinder 3 is opened. At this time, the solid waste falls between the two crushing rolls 5 for crushing treatment of the solid waste. By controlling the flow rate of the falling solid waste, the uniform crushing treatment of the solid waste is realized, and the problem that the crushing rolls 5 are stuck due to a large amount of solid waste directly falling between the two crushing rolls 5 is avoided, ensuring the progress of the crushing and recycling of solid waste and the efficiency of the crushing and recycling of solid waste.

[0044] The screening and reflux member 603 includes a spring telescopic column 6031, a screening plate 6032, a first belt connection mechanism 6033, a rotating shaft 6034, a second belt connection member 6035, a bevel gear connection structure 6036, a screw conveyor mechanism 6037, a guide plate 6038 and a cam 6039;

[0045] Inside the crushing box 1, spring telescopic columns 6031 are evenly installed by screws. The tops of several spring telescopic columns 6031 are connected by a screening plate 6032. The output shaft of the driving motor 601 is fixedly connected with a first belt connection mechanism 6033. Both ends of the bottom of the first belt connection mechanism 6033 are fixedly connected with rotating shafts 6034. A cam 6039 is fixedly sleeved on the outer side of the middle of the rotating shaft 6034. The bottom of the first belt connection mechanism 6033 is fixedly connected with a second belt connection member 6035. One end of the second belt connection member 6035 is fixedly connected with a bevel gear connection structure 6036 through a connecting shaft. Spiral conveying mechanisms 6037 are installed at both ends inside the crushing box 1 by screws. Guide plates 6038 are installed at both ends of the top of the screening plate 6032 by screws.

[0046] The first belt connection mechanism 6033 includes four first belt pulleys and two first belts. The output shaft of the driving motor 601 and the outer side of the end of one rotating shaft 6034 are fixedly sleeved with first belt pulleys. Two first belt pulleys are sleeved on the outer side of the other rotating shaft 6034. The first belt pulley on the output shaft of the driving motor 601 is connected with one first belt pulley on the other rotating shaft 6034 by a first belt. The first belt pulleys on the two rotating shafts 6034 are connected by a first belt. The rotating shaft 6034 is rotatably connected inside the crushing box 1. The outer side of the cam 6039 is in contact with the bottom surface of the screening plate 6032, realizing the rotation of the cam 6039, and further realizing the vibration of the screening plate 6032 to screen solid waste.

[0047] The spiral conveying mechanism 6037 includes a fixed cylinder and spiral conveying blades. The bevel gear connection structure 6036 includes two bevel gears. The two bevel gear connection structures 6036 are meshed. The spiral conveying blade is fixedly connected with one bevel gear. The other bevel gear is fixedly connected with the connecting shaft. The fixed cylinder is fixedly connected with the crushing box 1. Through holes are opened at one end of the top and bottom of the fixed cylinder, facilitating the entry of solid waste into the inside of the fixed cylinder, realizing the conveying of solid waste, and further realizing the secondary crushing of solid waste.

[0048] The guide plate 6038 is welded by a blocking plate, an anti-falling plate and an arc plate. The anti-falling plate is located outside the spiral conveying mechanism 6037. The blocking plate is located at both ends of the spiral conveying mechanism 6037, facilitating the guiding and blocking of solid waste, facilitating the entry of solid waste into the inside of the spiral conveying mechanism 6037, and when the guide plate 6038 moves, it can block some through holes at the bottom of the spiral conveying mechanism 6037, avoiding the problem of solid waste falling from the inside of the through holes.

[0049] After the broken solid waste falls to the top of the screening plate 6032, the rotating shaft 6034 is driven to rotate by the connection of the first belt connection mechanism 6033 at this time. The rotation of the rotating shaft 6034 drives the cam 6039 to rotate, so that the cam 6039 continuously contacts the screening plate 6032, causing the screening plate 6032 to vibrate, screening the broken solid waste, so that the qualified solid waste falls, and the unqualified solid waste flows into the spiral conveying mechanism 6037. At this time, through the connection of the second belt connecting piece 6035 and the bevel gear connection structure 6036, the spiral conveying blades can be driven to rotate when the rotating shaft 6034 rotates, conveying the inappropriate solid waste, and conveying the solid waste to the top of the diversion plate 604, so that the solid waste flows along the diversion plate 604 to be broken again between the two crushing rollers 5, so that the solid waste is broken to meet the requirements, improving the original crushing effect, eliminating the need for manual secondary crushing by personnel, enabling one-time crushing to be completed, improving the crushing efficiency and reducing the labor intensity of personnel.

[0050] Embodiment 2

[0051] On the basis of Embodiment 1, as Figure 2 、 Figure 9 and Figure 10 shown, the crushing member 607 includes a crushing shaft 6071 and crushing blades 6072;

[0052] The output shaft of the driving motor 605 is fixedly connected with the crushing shaft 6071. The crushing blades 6072 are uniformly and fixedly sleeved on the outside of the crushing shaft 6071. The crushing blades 6072 are located inside the feeding cylinder 3 to preliminarily crush the solid waste, facilitating the subsequent crushing of the solid waste.

[0053] The dust reduction member 608 includes a disc 6081, a connecting rod 6082, a driving rod 6083, a pressing plate 6084, a water outlet pipe 6085 and a water inlet pipe 6086;

[0054] One end of the crushing shaft 6071 is connected with a disc 6081 through a round shaft. One end of the disc 6081 is rotatably connected with a connecting rod 6082. One end of the connecting rod 6082 is rotatably connected with a driving rod 6083. The bottom of the driving rod 6083 is installed with a pressing plate 6084 through a screw. The water tank 606 is connected with the crushing box 1 through the water inlet pipe 6086. Both ends of the bottom of the water tank 606 are fixedly connected with the water outlet pipe 6085.

[0055] The pressing plate 6084 is inside the water tank 606. The water outlet pipe 6085 is connected to the water tank 606 through a first one-way valve, and the water inlet pipe 6086 is connected to the water tank 606 through a second one-way valve. The directions of the first one-way valve and the second one-way valve are opposite. The top of the water outlet pipe 6085 is fixedly installed at the top of the feeding cylinder 3. The top end of the water outlet pipe 6085 is evenly provided with water outlet holes, so that the water in the water tank 606 can only be discharged through the water outlet pipe 6085, and the water inside the water outlet pipe 6085 is prevented from flowing back into the water tank 606, which is convenient for intermittently spraying water into the feeding cylinder 3 for dust reduction.

[0056] When crushing solid waste, the crushing shaft 6071 rotates to drive the disc 6081 to rotate, and then drives the connecting rod 6082 to rotate. The rotation of the connecting rod 6082 drives the driving rod 6083 to move, and then drives the pressing plate 6084 to move inside the water tank 606. When the pressing plate 6084 moves downward, water is discharged through the water outlet pipe 6085 and sprayed out at the top of the feeding cylinder 3 to reduce dust, avoiding the problem of dust splashing, ensuring the use of the crushing equipment. When the pressing plate 6084 moves upward, the water flow is adsorbed into the water tank 606 through the water inlet pipe 6086, realizing the recycling of the water flow. At the same time, intermittent dust reduction is realized during dust reduction, which can reduce the water resources consumed by dust reduction and improve energy utilization efficiency.

[0057] The pusher 609 includes a third belt connecting piece 6091, a reciprocating threaded rod 6092 and a push plate 6093;

[0058] One end of the crushing shaft 6071 is fixedly connected with a third belt connecting piece 6091. One end of the bottom of the crushing box 1 is rotatably connected with a reciprocating threaded rod 6092. The reciprocating threaded rod 6092 is fixedly connected with one end of the third belt connecting piece 6091. The outer side of the reciprocating threaded rod 6092 is threadedly connected with a push plate 6093.

[0059] One end of the push plate 6093 is slidably connected inside the crushing box 1. The push plate 6093 is located at the bottom of one end of the discharge plate 610, which is convenient for pushing the crushed solid waste to move.

[0060] When the crushing shaft 6071 rotates, the reciprocating threaded rod 6092 is driven to rotate through the third belt connecting piece 6091. Through the threaded connection between the reciprocating threaded rod 6092 and the push plate 6093, the push plate 6093 is driven to move, pushing the flowing solid waste to move, avoiding the problem that the solid waste accumulates at one end of the crushing box 1 and causes blockage at one end of the discharge plate 610, affecting the discharge of the solid waste.

[0061] Turn on the drive motor 601, the crushing motor 4 and the driving motor 605, and add solid waste into the feed cylinder 3. The solid waste enters the inside of the crushing box 1 through the feed cylinder 3. The output shaft of the driving motor 605 drives the crushing blade 6072 to rotate, crushing the solid waste to reduce its volume, which is convenient for subsequent crushing treatment of the solid waste. During the crushing treatment of the solid waste, the pressing plate 6084 moves inside the water tank 606, causing the water inside the water tank 606 to enter the inside of the feed cylinder 3 for dust suppression, avoiding the problem of dust splashing and affecting the surrounding buffer and personnel, and ensuring the operation of the crushing device. At the same time, the pushing plate 6093 will also move accordingly, which can push the crushed solid waste to both ends of the crushing box 1, avoiding the problem of the solid waste accumulating at the outlet of the crushing box 1 and affecting the subsequent discharging. Through the operation of the drive motor 601, the rotating plate 6024 continuously reciprocates, realizing the continuous opening and closing of the bottom of the feed cylinder 3, achieving uniform feeding of the solid waste, and avoiding the problem of the solid waste accumulating on the top of the crushing roller 5 and affecting the crushing of the solid waste. The crushed solid waste falls onto the top of the screening plate 6032, which can vibrate the screening plate 6032 to screen the solid waste. At this time, the unqualified solid waste enters the inside of the screw conveyor mechanism 6037 along the screening plate 6032. At this time, the screw conveyor mechanism 6037 runs synchronously with the rotation of the rotating shaft 6034, causing the solid waste to flow back between the two crushing rollers 5 for re-crushing until the solid waste is crushed to meet the requirements.
