Description

Technical Field

[0001] This invention relates to the field of environmental protection technology for sludge treatment, specifically to a material distribution mechanism and a sludge silo. Background Technology

[0002] Sludge conveying and storage equipment is an indispensable part of all sludge treatment projects. As a key piece of equipment for sludge storage, the performance and stability of sludge silos directly affect the output of the entire sludge treatment project.

[0003] The existing sludge silo includes a silo body, an inlet, sludge accumulation areas, a discharge slide, a discharge conveyor screw conveyor, and a hydraulic cylinder. Sludge enters the silo body through the inlet and accumulates inside. A discharge slide is located at the bottom of the silo body, and the push rod of the hydraulic cylinder is connected to the slide. The movement of the hydraulic cylinder drives the slide in a reciprocating motion. During this motion, the sludge within the slide's coverage area is continuously pushed into the screw conveyor trough, achieving the discharge effect. The sludge that falls into the trough is then transported to the outlet by the rotating screw conveyor and discharged.

[0004] However, traditional sludge silos use a single inlet for feeding, and the sludge itself has low fluidity, causing it to accumulate excessively high after entering the silo, forming a cone-shaped apex. This results in the inability to fully utilize the effective volume of the silo, leading to a waste of silo space.

[0005] In view of this, there is an urgent need for a solution that can improve the utilization rate of the effective volume of the warehouse. Summary of the Invention

[0006] One objective of this invention is to provide a new technical solution for a fabric feeding mechanism and a sludge storage tank. By improving the structure of the sludge storage tank, the utilization rate of the effective volume of the tank is significantly increased.

[0007] In one aspect, the present invention provides a material distribution mechanism for a sludge silo. The material distribution mechanism includes a material distribution section horizontally disposed within the silo body and fixedly connected to the inner wall of the silo.

A material pushing shaft is vertically disposed within the material distribution section. The material pushing assembly is fixedly connected to the material pushing shaft. The drive component is used to output power to the material pushing shaft. Under the drive of the material pushing shaft, the material pushing assembly rotates in a horizontal plane.

[0008] This method allows sludge to fall into the bottom of the silo through multiple discharge holes, improving the uniformity of sludge distribution. This avoids the formation of a single large cone-shaped apex when sludge falls into the silo, as is common in traditional designs, thus improving the utilization rate of the silo's effective volume. Furthermore, the more even stress distribution at the bottom of the silo enhances the overall stability of the sludge silo.

[0057] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] According to one embodiment of this application, such as Figure 1 As shown, a material distribution mechanism 1 is provided. This material distribution mechanism 1 is used in a sludge silo, which includes a silo body 3, which is formed by a top plate 31, a bottom plate 33, and side plates 34. An inlet 32 ​​is provided on the top plate 31 of the silo body 3. Sludge enters the silo body 3 through the inlet 32.

[0059] like Figure 1 andFigure 2 As shown, the fabric feeding mechanism 1 includes a fabric feeding section 2. The fabric feeding section 2 is located inside the bin body 3 and is horizontally fixed to the inner wall of the bin, for example, by welding. For example, the fabric feeding section 2 includes a connecting part 21 and a fabric feeding plate 22. The connecting part 21 surrounds the fabric feeding plate 22 and is the portion that is fixedly connected to the inner wall of the bin. The fabric feeding plate 22 is located in the middle of the connecting part 21. The fabric feeding plate 22 is positioned corresponding to the feed inlet 32 ​​of the bin body 3. The projection range of the feed inlet 32 ​​on the horizontal plane is within the projection range of the fabric feeding plate 22 on the horizontal plane.

[0060] Optionally, to increase the area of ​​the fabric plate 22 and improve the uniformity of material feeding, the fabric plate 22 is circular, and the pusher shaft 27 is rotatably disposed at the center of the fabric plate 22. The center of the fabric plate 22 is the center of the fabric section 2.

[0061] It is understood that the connecting part 21 can also be a plate-shaped structure integrally formed with the fabric plate 22, or it can be a frame fixedly connected to the inner wall of the bin. Those skilled in the art can choose according to their needs, as long as the fabric plate 22 can be fixed to the bin body 3.

[0062] Multiple material drop holes 23 are provided inside the fabric plate 22. The material drop holes 23 penetrate the fabric section 2 along the thickness direction of the fabric section 2.

[0063] The fabric feeding mechanism 1 includes a feeding assembly 25, a mounting rod 251, a drive component 26, and a feeding shaft 27. The drive component 26 is used to output power to the feeding shaft 27. The drive component 26 is, for example, a drive motor, and the output end of the drive motor is connected to the feeding shaft 27.

[0064] For example, such as Figure 1 as well as Figure 2 As shown, a mounting hole (not shown) is provided on the top plate 31 of the bin body 3. The drive motor is fixed to the outer surface of the top plate 31, and the output shaft of the drive motor is aligned with the mounting hole. The pusher shaft 27 is located inside the bin body 3 and is vertically mounted on the material distribution plate 22. For example, the pusher shaft 27 is rotatably connected to the material distribution plate 22 via a base 271, and the main body of the pusher shaft 27 is pivotally connected to the base 271. The top end of the shaft away from the base is connected to the output shaft of the drive motor via a coupling 272, which is embedded in the mounting hole of the top plate 31.

[0065] The material pushing assembly 25 is located between the top plate 31 of the sludge silo and the material distribution section 2. The material pushing assembly 25 is fixedly connected to the material pushing shaft 27. Driven by the material pushing shaft 27, the material pushing assembly 25 rotates in the horizontal direction.

[0066] The sludge is located within the rotation range of the pusher assembly 25. The rotation range of the pusher assembly 25 refers to the space formed by the pusher assembly 25 rotating one revolution along the pusher shaft 27. After the sludge falls into the distribution plate 22 from the feed inlet 32, it is located within the rotation range of the pusher assembly 25 and can contact the pusher assembly 25 and be pushed along the rotation direction of the pusher assembly 25.

[0067] See Figure 2 as well as Figure 3 When the sludge silo is in operation, sludge enters through the inlet 32 ​​and accumulates on the distribution plate 22 of the distribution section 2. The drive component 26 starts working, and the pusher shaft 27 starts rotating under the drive of the drive component 26. The pusher assembly 25 rotates horizontally under the drive of the pusher shaft 27, pushing the sludge to move in the same direction as the rotation of the pusher assembly 25. When the sludge to be pushed moves to the discharge hole 23, it falls into the bottom of the silo body 3 through the discharge hole 23.

[0068] This method allows sludge to fall into the bottom of the silo body 3 through multiple discharge holes 23, improving the uniformity of sludge distribution. This avoids the formation of a single large cone-shaped apex within the silo body 3, as seen in traditional designs, thus improving the utilization rate of the silo body 3's effective volume. Furthermore, the more uniform stress distribution at the bottom of the silo body 3 enhances the overall stability of the sludge silo.

[0069] In one example, the pusher assembly 25 includes at least one mounting rod 251. The mounting rod 251 is a horizontally positioned rod-shaped component. The mounting rod 251 is fixed to the pusher shaft 27 and extends radially. One end of the mounting rod 251 is fixed to the axial side wall of the pusher shaft 27, or the middle portion of the mounting rod 251 may be fixed to the axial side wall of the pusher shaft 27. The mounting rod 251 is arranged parallel to the fabric plate 22 and extends radially along the fabric plate 22.

[0070] like Figure 1 and Figure 3 As shown, a push plate 252 extending in the same direction is provided on the mounting rod 251. The horizontal extension direction of the push plate 252 coincides with the extension direction of the mounting rod 251. The push plate 252 is set perpendicular to the cloth distribution plate 22. When the push plate 252 and the mounting rod 251 rotate together in the horizontal direction, the push plate 252 can push the sludge to move in its rotation direction. For example, the lower surface of the push plate 252 in the vertical direction is close to the upper surface of the cloth distribution plate 22, that is, close to the surface of the cloth distribution plate 22 that carries the sludge.

[0071] To further improve the uniformity of sludge pushing by the feeding assembly 25, and thus further improve the uniformity of material distribution by the feeding plate 22, such as... Figure 3 As shown, a guide plate 253 is provided at the middle of at least one mounting rod 251, and the guide plate 253 is arranged at an angle to the corresponding mounting rod 251 in the horizontal direction.Figure 2 As shown, the angle between the guide plate 253 and the corresponding mounting rod 251 is α, where α is the included angle between the guide plate 253 and the mounting rod 251 on the side closest to the pusher shaft 27.

[0072] The guide plate 253 and push plate 252 can push the sludge in a circular motion perpendicular to its surface. Thus, the guide plate 253 and the mounting rod 251 are angled together, which can change the tendency of the sludge to move when pushing it. This pushes the sludge in different directions, avoiding uneven feeding caused by pushing the sludge in only one direction.

[0073] To increase the structural strength of the guide plate 253, a reinforcing plate 254 is connected between the guide plate 253 and the mounting rod 251, and a push plate 252 is fixed to the side of the reinforcing plate 254 away from the guide plate 253.

[0074] Multiple mounting rods 251 are fixed circumferentially to the pusher shaft 27, and the rotation range of the push plates 252 fixed to the multiple mounting rods 251 together covers the distribution plate 22. In this way, while the guide plate 253 guides the sludge, the multiple push plates 252 can cover the sludge within the distribution plate 22, avoiding any omissions.

[0075] like Figures 1-3 As shown, the system includes multiple guide plates 253, each fixed to a different mounting rod 251. The guide plates 253 include a first guide plate 253-1 and a second guide plate 253-2. The angle between the first guide plate 253-1 and its corresponding mounting rod is between 90° and 45°. The angle between the second guide plate 253-2 and its corresponding mounting rod 251 is less than 45°.

[0076] For example, such as Figure 2 and Figure 3 As shown, the plurality of mounting rods 251 include a first mounting rod 251-1, a second mounting rod 251-2, and a third mounting rod 251-3. A first guide plate 253-1 is fixed to the first mounting rod 251-1. The first guide plate 253-1 is deflected at a certain angle toward the side where the pusher shaft 27 is located, so that an angle α1 is formed between the first guide plate 253-1 and the first mounting rod 251-1, where 90° < α1 ≤ 45°. When the first guide plate 253-1 moves in a circular motion along the pusher shaft 27, it can push the sludge in front to move in the direction shown in V1 in the figure. V1 is a direction perpendicular to the first guide plate 253-1, and the sludge moves toward the inner side of the rotation center where the pusher shaft 27 is located.

[0077] A second guide plate 253-2 is fixed to the second mounting rod 251-2. The second guide plate 253-2 is deflected at a certain angle away from the side where the pushing shaft 27 is located, so that the second guide plate 253-2 and the second mounting rod 251-2 form an angle α2, where 45° < α2 < 0°. When the second guide plate 253-2 moves in a circular motion along the pushing shaft 27, it can push the sludge in front to move in the direction shown in the figure, where V2 is a direction perpendicular to the second guide plate 253-2. The sludge moves towards the outside of the rotation center where the pushing shaft 27 is located. Among them, the first guide plate 253-1 is closer to the side where the pushing shaft 27 is located compared with the second guide plate 253-2.

[0078] like Figure 2 As shown, sludge enters the silo 3 through the feed inlet 32 ​​of the top plate 31, falls into the discharge area 24 of the cloth distribution section 2, and accumulates to a certain height. A second drive component fixed to the outer surface of the top plate 31 drives the pusher shaft 27 to rotate, which in turn drives the mounting rod, the push plate fixed to the mounting rod, and the guide plate to rotate together. The angle α2 between the second guide plate 253-2 and the mounting rod is 40°, and the angle α1 between the first guide plate 253-1 and the mounting rod is 75°. Thus, the first guide plate 253-1 pushes the sludge along the V1 direction, allowing the sludge to be distributed to... Figure 2 Within the annular region R1 of the middle feeding plate 22, the second guide plate 253-2 pushes the sludge to move along the V2 direction, and the sludge is distributed to... Figure 2 Within the annular region R3 of the middle fabric plate 22.

[0079] A first push plate 252-1 is mounted on a first mounting rod 251-1 on which a first guide plate 253-1 is installed. A first reinforcing plate 254-1 is installed between the first guide plate 253-1 and the first push plate 252-1. One end of the first reinforcing plate 254-1 is spaced apart from and fixed to the first mounting rod 251-1, and the other end of the first reinforcing plate 254-1 is fixed to the end of the first guide plate 253-1 away from the first mounting rod. When the first guide plate 253-1 pushes the sludge, the first reinforcing plate 254-1 provides support for the first guide plate 253-1.

[0080] In the radial direction, the first push plate 252-1 is fixed to the outside of the first push plate 252-1, and the radial dimension of the first push plate 252-1 is consistent with the radial dimension of the annular region R3 of the fabric plate 22. The radial dimension of the annular region is the width of the annular region in the radial direction of the fabric plate 22.

[0081] like Figure 3As shown, similarly, the second push plate 252-2 is fixed on the side of the second reinforcing plate 254-2 away from the second guide plate 253-2, and the second push plate 252-2 is fixed on the side close to the push shaft 27. The radial dimension of the second push plate 252-2 is consistent with the radial dimension of the annular region R1. A third push plate 252-3 is installed on the first mounting rod 251-1. The radial dimension of the third push plate 252-3 is consistent with the dimension of the annular region R2 of the fabric plate 22.

[0082] Multiple discharge holes 23 are provided in the annular areas R1, R2 and R3. The sludge distributed to different areas of the distribution plate 22 falls into the bottom of the bin 3 through the discharge holes 23 under the push of the push plate.

[0083] In this way, the sludge can be evenly filled into the hopper 3. Furthermore, the sludge can be distributed to different annular areas of the spreading plate, thus enabling rapid spreading of the spreading mechanism and increasing the spreading rate.

[0084] Optionally, the radial dimensions of the annular regions R1, R2, and R3 are identical. The area ratio of these annular regions R1, R2, and R3 is 1:3:6. The ratio of the amount of sludge pushed by the second pusher plate 252-2, the third pusher plate 252-3, and the first pusher plate 252-1 is 1:3:6. Within this range, the efficiency of the sludge handling mechanism can be further improved.

[0085] It is understandable that the radial dimensions of the annular regions R1, R2, and R3 may not be equal. This is subject to the design requirements of those skilled in the art, and no specific limitations are made here.

[0086] According to other embodiments of the invention, a sludge silo is provided. For example... Figure 1 As shown. The first direction (z-axis direction) is the direction perpendicular to the paper in the horizontal plane, that is... Figure 1 The first direction is the z-axis, the second direction is the x-axis, the direction perpendicular to both the z-axis and x-axis is the y-axis, and the y-axis is the vertical direction.

[0087] like Figure 1 As shown, the sludge silo includes a silo body 3 and the aforementioned material distribution mechanism 1. The silo body 3 includes a top plate 31, a bottom plate 33, and side plates. The side plates include a first side plate 341 and a second side plate 342 arranged opposite each other in a second direction (x-axis direction). A feed inlet 32 ​​is provided on the top plate 31. The sludge silo also includes a cutter roller 6, at least partially disposed within the silo body 3. The cutter roller 6 is used to transport the sludge within the silo body 3 to the discharge port 79 and discharge it from the silo body 3.

[0088] Figure 1The intermediate cutter roller 6 passes through the bottom plate 33 of the chamber 3 along the second direction (x-axis direction). The axial direction of the cutter roller 6 is parallel to the second direction (x-axis direction). The cutter roller 6 can rotate along the central axis under the drive of the first cutter roller drive assembly 65.

[0089] The sludge silo is equipped with a transverse drive assembly 9. The transverse drive assembly 9 is located outside the silo body 3. A guide component 41 is fixed on a fixed bracket 4. For example, the guide component is a strip-shaped guide rail. The guide component 41 extends in a first direction (z-axis direction) on a horizontal plane. The transverse drive assembly 9 drives the cutter roller 6 to move along the guide component 41. At least one end of the cutter roller 6 extends out of the silo body 3 and is slidably connected to the guide component 41. The cutter roller 6 forms a sealed connection with the silo body 3 through a sealing component 7.

[0090] By placing the guide component 41 on the outside of the bin body 3, sludge at the bottom of the bin body 3 is prevented from covering the guide component 41. The resistance of the cutter roller 6 when moving along the guide component 41 is reduced, thereby optimizing the operating environment of the cutter roller 6 and improving the stability of the cutter roller 6 operation.

[0091] Furthermore, the middle portion of the cutter roller 6 is located within the chamber 3, with at least one end extending from the chamber 3 and connected to the guide member 41. This reduces the portion of the cutter roller 6 that bears the pressure of the sludge, lowering the structural strength requirements of the cutter roller 6. It also reduces the propulsive force required by the transverse drive assembly 9 to drive the cutter roller 6.

[0092] Optionally, both ends of the cutter roller 6 extend out of the chamber body, and guide components 41 that are opposite to both ends of the cutter roller 6 are fixed on the fixed bracket 4. The guide components 41 can respectively cooperate with both ends of the cutter roller 6.

[0093] This improves the stability of the cutter roller 6 during operation. At the same time, only the middle part of the cutter roller 6 bears the pressure of the sludge, further reducing the strength requirements of the cutter roller.

[0094] In one example, cutting blades 61 are disposed on the outer surface of the cutter roller 6, and the cutting blades 61 are distributed in an array. For example, as shown... Figure 6 As shown, multiple cutting blades 61 are spaced apart along the axial direction of the cutter roller 6 to form blade groups, and multiple blade groups are arranged around the cutter roller 6 in the circumferential direction.

[0095] like Figure 7 and Figure 8 As shown, the cutter roller 6 rotates in the direction indicated by arrow S in the figure, and the cutting side 62 of the cutting blade 61 is arranged radially along the cutter roller 6. The angle between the bottom of the cutting side 62 and the tangent L of the radial section of the cutter roller 6 and the plane P on which the cutting side 62 is located is α. 3， α3 is preferably 30°. The cutting side 62 is the side of the cutting blade 61 used to cut the soil. The cutter roller 6 rotates clockwise or counterclockwise.

[0096] like Figure 7 As shown, when the cutter roller 6 is working, it moves forward and backward along the first direction (z-axis direction) under the drive of the transverse drive assembly 9. Simultaneously, the cutter roller 6 itself rotates under the drive of the cutter roller drive assembly 65. The transverse drive assembly 9 provides a kinetic force along the first direction (z-axis direction), causing the cutter roller 6 to squeeze and push the sludge located at the front of its kinetic direction. At the same time, the rotating cutter roller 6 drives the cutting blades 61 to cut and feed the sludge, thereby chopping it up. The chopped sludge, pushed by the cutter roller 6, falls into the cavity 63 through the discharge port 79 and is discharged from the bin 3 through the discharge screw assembly 8.

[0097] By equipping the cutter roller 6 with cutting blades 61, the cutter roller 6 has a crushing function. This allows the cutter roller 6 to move back and forth along the second direction (x-axis direction) to push the sludge at the bottom of the silo 3 while simultaneously breaking up the hardened sludge clumps at the bottom of the silo 3. This avoids the cutter roller 6 getting stuck due to the hardened clumps at the bottom of the silo 3, significantly reducing the downtime rate of the sludge silo.

[0098] For example, see Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The cutter roller 6 is a tubular component with a cavity 63. The cutter roller 6 has a mud-breaking port 64, which is located on the cutting side 62 of the cutting blade 61. The mud-breaking port 64 extends through the cutter roller 6 along its thickness direction.

[0099] For example, such as Figure 1 as well as Figure 6 As shown, a discharge screw assembly 8 is provided within the cavity 63, extending axially along the cutter roller 6. The discharge port 79 is located on the first discharge side 82 of the discharge screw assembly 8. The discharge screw assembly 8 has a discharge shaft 81 and a spiral plate-shaped structure fixed outside the discharge shaft 81. Sludge enters the cavity 63 through the sludge fragmentation port 64 and falls into the spiral plate-shaped structure. The discharge shaft 81 rotates along its central axis, and driven by the discharge shaft 81, the spiral plate-shaped structure begins to rotate. During the rotation of the spiral plate-shaped structure, the sludge fragments are transported to the discharge port 79 located on the first discharge side 82.

[0100] like Figure 7 and Figure 8As shown, during the rotation of the cutter roller 6, the sludge fragments cut by the cutting blade 61 enter the cavity 63 from the sludge material inlet 64 under the combined action of the cutter roller 6 and the sludge in the first direction (z-axis direction). The discharge screw assembly 8, located within the cavity 63, transports the sludge fragments to the discharge port 79 during rotation. The sludge fragments then enter the receiving mechanism 5 from the discharge port 79 and are conveyed by the receiving screw assembly 53 to the next working stage.

[0101] In this manner, the transverse drive assembly 9 drives the cutter roller 6 to reciprocate along the first direction (z-axis direction) at the bottom of the hopper 3. Sludge along the movement path of the cutter roller 6 is discharged from the sludge hopper. Sealing components 7 located on both sides of the hopper 3 can seal the hopper 3 to prevent sludge overflow.

[0102] In this way, the cutting blade 61 cooperates with the sludge crushing inlet 64 to crush the sludge and then convey it through the sludge crushing inlet 64 to the discharge screw assembly 8 inside the cutter roller 6. This improves the uniformity of discharge and avoids the difficulty in discharge caused by sludge caking. It also prevents the sludge from being unable to be discharged from the silo due to sludge caking.

[0103] In one example, sealing components 7 are respectively provided on the first side plate 341 and the second side plate 342. Both ends of the cutter roller 6 extend out of the chamber body 3 and are sealed to the chamber body 3 through the corresponding sealing components 7.

[0104] For example, a strip-shaped through hole is provided in the first side plate 341 and the second side plate 342, and the strip-shaped through hole extends along a first direction (z-axis direction). The sealing member 7 is configured to cover the strip-shaped channel when the cutter roller 6 moves along the first direction.

[0105] For example, the cutter roller 6 includes a driving end and a driven end, with the driving end being the end connected to the cutter roller drive assembly 65. The cutter roller drive assembly 65 is used to drive the cutter roller 6 to rotate along its central axis.

[0106] Specifically, the sealing components 7 located on both sides of the chamber 3 each include a fixed plate and a bracket fixed to the fixed plate. The fixed plate located on the same side as the driving end of the cutter roller 6 is the first fixed plate 73, and the fixed plate located on the same side as the driven end of the cutter roller 6 is the second fixed plate 74. Two telescopic portions 75 are respectively provided on opposite sides of the first fixed plate 73 and the second fixed plate 74 in the first direction (z-axis direction). The driving end of the cutter roller 6 extends into the first bracket 71 on the first fixed plate 73 and is pivotally connected to the first bracket 71. The driven end of the cutter roller 6 extends into the second bracket 72 on the second fixed plate 74 and is pivotally connected to the second bracket 72.

[0107] When the first fixed plate 73 and the second fixed plate 74 move to the first limit position under the push of the cutter roller 6, the first fixed plate 73 and the second fixed plate 74 can correspondingly compress one of the two telescopic parts 75, and the other of the two telescopic parts 75 is in the unfolded state under the drive of the first fixed plate 73 and the second fixed plate 74.

[0108] For example, when the first fixed plate 73 and the second fixed plate 74 move to the second limit position under the push of the cutter roller 6, the telescopic part 75, which was originally in a compressed state, changes to an unfolded state, and the telescopic part 75, which was originally in an unfolded state, changes to a compressed state.

[0109] Each sealing component 7 includes a slide rail 731. The slide rail 731 is positioned along the height direction on the upper and lower sides of the strip-shaped channel and extends along a first direction (z-axis direction). A fixing plate covers the outside of the strip-shaped through-hole. The fixing plate is embedded in the upper and lower sides in the vertical direction and can slide along the slide rail 731. A through-hole for the cutter roller 6 is provided on the fixing plate to allow the end of the cutter roller 6 to pass through. The through-hole of the cutter roller 6 and the cutter roller 6 located therein form a clearance fit. The cutter roller 6 can rotate within the through-hole of the cutter roller 6.

[0110] Specifically, each sealing component 7 includes multiple stacked baffles 77, which are slidably connected to the slide rail 731. A barb structure 78 is provided on the adjacent sides of adjacent baffles 77. The baffles 77 unfold one by one under the action of the fixed plate, and the barb structure 78 limits and connects adjacent baffles 77.

[0111] For example, the support is a cylindrical structure with an open end, which is fixed to a corresponding fixing plate. The open end of the support is fixed to the outside of the through hole of the cutter roller 6 in the radial direction. The end of the cutter roller 6 extends into the support through the cutter roller through hole. Bearings are provided on the inner wall of the support, and the cutter roller 6 is pivotally connected to the support through the bearings.

[0112] In one example, the material discharge port 79 is positioned on the second bracket 72 to facilitate maintenance of the material discharge port 79.

[0113] In one example, for ease of maintenance, the cutter roller drive assembly 65 is disposed outside the first bracket 71. The drive shaft of the cutter roller drive assembly 65 extends into the first bracket 71 and connects to the cutter roller 6, and outputs power to the cutter roller 6 to drive the cutter roller 6 to rotate.

[0114] In one example, the driven end of the discharge screw assembly 8 is pivotally connected to the driving end of the cutter roller 6, and the driving end of the discharge screw assembly 8 extends from the driven end of the cutter roller 6 and is connected to the discharge screw drive assembly 83 located outside the second bracket 72.

[0115] like Figure 1 as well as Figure 6As shown, the active end of the discharge screw assembly 8 is located on one side of the second bracket 72. The discharge screw drive assembly 83 is located outside the second bracket 72. The drive shaft of the discharge screw drive assembly 83 extends into the second bracket 72 and is connected to the discharge shaft 81 of the discharge screw assembly 8 to drive the discharge shaft 81 to rotate along its central axis.

[0116] For example, the discharge screw assembly 8 is coaxially arranged with the cutter roller 6. The driving end of the discharge screw assembly 8 extends from the driven end of the cutter roller 6, and the first discharge side 82 of the discharge screw assembly 8 is located on the side where the driving end of the discharge screw assembly 8 is located. The driven end of the discharge screw assembly 8 is located in the cavity 63 of the cutter roller 6 and is pivotally connected to the driving end of the cutter roller 6. A bearing is provided on the cavity wall located on the side of the driving end of the cutter roller 6, and the discharge shaft 81 is disposed in the bearing and rotatably connected to the bearing.

[0117] In one embodiment of the present invention, a lateral drive assembly 9 is further included. The lateral drive assembly 9 includes a lateral drive motor 91 and a transmission component. The transmission component includes a connecting rod 92, a rack 93 extending along a first direction (z-axis direction), and a gear 94 meshing with the rack 93. The connecting rod 92 is fixedly connected to a first bracket 71, and the other end of the connecting rod 92 is fixedly connected to the gear 94. The gear 94 is connected to the output end of the lateral drive motor 91.

[0118] The transverse drive motor 91 is located outside the first bracket 71, and the rack 93 extends in the same direction as the guide member 41. The output shaft of the transverse drive motor 91 is built into the gear 94 and can drive the gear 94 to rotate. With the cooperation of the gear 94 and the rack 93, the transverse drive motor 91 and the gear 94 can move along the extension direction of the rack 93, and at the same time drive the cutter roller 6 to move along the guide member 41 in the first direction (z-axis direction) through the connecting rod 92.

[0119] In one embodiment of this application, a receiving mechanism 5 is also included. The receiving mechanism 5 includes a receiving bin 51, which includes a receiving port 52. A discharge port 79 extends into the receiving port 52 and is movable relative to the receiving port 52. A receiving screw assembly 53 is provided inside the receiving bin 51, and the receiving screw assembly 53 is arranged in a direction perpendicular to the discharge screw assembly 8. The receiving screw assembly 53 includes a first part 531 and a second part 532. A discharge port 54 is opened at the bottom of the receiving bin 51, and the discharge port 54 is located between the first part 531 and the second part 532. The discharge port 54 is located on the second discharge side of the first part 531 and the second part 532. In this way, sludge can be discharged to the location of the designated discharge port 54.
