Description

Technical Field

[0001] This invention belongs to the field of material transportation technology, and specifically relates to a quantitative filling and conveying device for solidified soil packaging. Background Technology

[0002] Solidified soil: This is an engineering material that gives loose soil a certain strength, stability and durability by adding a solidifying agent and then undergoing a series of chemical or physical reactions. It can be various types of natural soil, such as clay, sand or silt. The particle size, gradation and mineral composition of different types of soil constantly affect the transportation and packaging efficiency of solidified soil.

[0003] Clay particles are small and have high surface energy, giving them strong adhesion. In addition, clay usually contains a certain amount of moisture, which further enhances the bonding force between clay particles. Therefore, when transported by a screw pump, clay particles will continuously adhere to the inner wall of the screw pump, the screw surface, and the port. Over time, the clay will continuously deposit and solidify, causing the effective flow cross-sectional area at the port to gradually decrease.

[0004] Furthermore, there is a certain gap between the screw and the pump casing in the screw pump. When conveying clay, fine particles in the clay continuously enter the aforementioned gap. During this process, the fluid flow resistance increases due to the deposition and solidification of clay at the port, which further leads to a decrease in the outlet pressure and an increase in the inlet pressure of the screw pump, until it affects the overall conveying stability of the screw pump. That is, pressure loss occurs at the port, and the pressure in the middle part of the pump pipe is insufficient, affecting the smoothness of clay conveying. Moreover, as the operating time increases, clay continues to accumulate in the gap, the friction between the screw and the pump casing increases, the effective flow cross-sectional area at the port gradually decreases, and it may even change the gap between the screw and the bushing, reducing the service life of the seals. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative filling and conveying device for solidified soil packaging, comprising a material distribution hopper, the inside of which is a hollow structure, and the material distribution hopper is composed of two parts that are interlocked together.

A central shaft gear meshing with the rack is engaged on the outer wall of the column. Connecting plates are engaged on both ends of the side rails on the side face near the top plate. A mouth ring that is slidably engaged with the packing tube is engaged on the end of the connecting plate away from the rack. An ear seat is engaged on the end face of the mouth ring away from the rack. One of the two ear seats in the same packing tube area is engaged with a sleeve, and the other ear seat is engaged with a guide rod that is slidably engaged with the sleeve. A telescopic spring is sleeved on the outer wall of the guide rod.

[0026] Two corner brackets are installed symmetrically and snap-fit ​​on the outer wall of the hopper on the side away from the conveying pipe.

[0027] The rails are snap-fitted and installed in the middle of the horizontal section of the corner frame.

[0029] Empty shelf, sliding snap-fit ​​installation on the horizontal section of corner shelf, and the empty shelf is snap-fit ​​installation with the movable end of telescopic cylinder;

[0030] The crossbar is installed in the middle of the empty shelf using a snap-fit ​​mechanism.

[0031] The steel ring is snap-fitted and installed on the outer wall of the crossbar;

[0032] There are three brackets, which are snapped onto both ends of the outer wall of the steel ring. Two brackets are distributed on the end of the steel ring closest to the telescopic cylinder, and one bracket is distributed on the other end.

[0033] The planetary gear is mounted in the middle of the two brackets near one end of the telescopic cylinder via a rotating shaft.

[0034] Preferably, a vertical rod is rotatably mounted between the two supports at both ends. The outer wall of the vertical rod has a snake-mouth groove. A scraper is snapped onto the outer wall of the steel ring, and the end of the scraper away from the axis of the steel ring is chamfered at a right angle. Two corner shovels are slidably snapped onto the outer wall of the scraper and are slidably mounted on the steel ring. In addition, the vertical distance between the two corner shovels is at least five centimeters. An angle plate is snapped onto the end of the two corner shovels away from the axis of the steel ring. A matching plate is snapped onto the end face of the angle plate near the vertical rod. A steel ball that mates with the snake-mouth groove is rotatably mounted on the end of the matching plate near the vertical rod.

[0035] Preferably, the depth of the corner ring axis is greater than the depth of the tie ring axis; the length of the part of the discharge pipe entering the hopper is less than the depth of the tie ring axis; the vertical distance between the end face of the corner ring near the rack and the end face of the top plate near the corner ring is greater than the depth of the tie ring axis; the vertical distance between the end face of the scraper away from the crossbar axis and the steel ring axis is equal to the inner radius of the packing tube; the vertical distance between the end face of the planetary gear away from the crossbar and the steel ring axis is less than the inner radius of the packing tube; furthermore, the vertical distance between the end of the support and the vertical rod away from the crossbar axis and the steel ring axis is also less than the inner radius of the packing tube; and the lengths of the steel ring and the vertical rod are both greater than the length of the packing tube.

[0036] The method for quantitative and stable conveying of solidified soil employs the aforementioned quantitative filling and conveying device for solidified soil packaging. The specific steps are as follows:

[0037] S1: First, the support column moves synchronously with the rib plate under the control of the bridge slide rail until the positions of the packing pipe and the conveying pipe are interchanged at different positions. Then, the rack is controlled by the central shaft gear to drive the mouth ring to move towards or away from each other under the guidance of the packing pipe until the ball is tangent to the electrode ring.

[0038] S2: Then, the telescopic cylinder drives the empty layer frame under the guidance of the strip plate, so that the crossbar drives the steel ring to move into the stuffing tube until the scraper fully covers the inner wall of the stuffing tube in the axial direction. After that, the crossbar drives the steel ring to rotate. During this process, the vertical bar rotates at a different speed than the crossbar through the meshing between the planetary gear and the gear ring.

[0039] S3: Finally, through the interaction between the snake mouth groove and the steel ball, the steel ball synchronously controls the positioning plate to drive the corner plate to move. After that, under the combined guidance of the steel ring and the scraper, the corner scraper synchronously follows the corner plate to reciprocate along the crossbar axis. At the same time, the cleaning liquid stored in the water tank is gradually guided to the spray pipe through the water guide pipe, so as to cooperate with the scraper to clean the inner wall of the packing tube, thereby improving the cleaning effect and cleaning ability.

[0040] The present invention has the following beneficial effects:

[0041] 1. In this invention, the stiffening plate controls the packing pipe to reciprocate synchronously with the bridge slide rail under the connecting force of the support bridge. This achieves alternating docking between the packing pipe and the conveying pipe, ensuring the cleanliness of the packing pipe under the same conveying pipe connection state. This avoids downtime caused by clay deposition on the wall of a single conveying pipe, thereby enhancing the stability of the conveying system, balancing the pipeline conveying pressure per unit time, reducing production interruptions caused by clay deposition or solidification on the inner wall of the pipeline, and helping to improve production safety. At the same time, it stabilizes the effective flow cross-sectional area at the port of the conveying pipe, ensuring the efficiency of clay conveying and packaging.

[0042] 2. This invention achieves the simultaneous movement of the mouth ring and the corner ring towards the middle of the packing tube during the packing tube repositioning by moving the side rails in opposite directions or in opposite directions. This releases the contact seal between the mouth ring and the conveying tube, and avoids collision and limitation between the packing tube and the binding ring during the repositioning process, which helps to improve the service life of the corner ring, packing tube, and binding ring. At the same time, the elasticity of the extension spring itself buffers and degrades the radial or axial runout between the guide rod and the sleeve, further improving the alignment accuracy between the packing tube and the conveying tube, reducing leakage, and improving conveying accuracy and efficiency.

[0043] 3. This invention uses a hollow frame, driven by a telescopic cylinder and guided by rails, to control a crossbar that moves a steel ring into the packing tube until the scraper completely covers the inner wall of the packing tube. Afterward, the crossbar controls the steel ring to rotate the scraper. During this process, the meshing between the planetary gears and the gear ring causes the vertical bar to rotate at a different speed than the steel ring. Subsequently, the snake-mouth groove continuously interacts with the steel balls during the vertical bar's rotation, causing the angle shovel to reciprocate along the crossbar axis under the combined guidance of the steel ring and the scraper. This ensures that while the scraper rotates, the angle shovel performs scraping work on the scraper, guaranteeing the cleanliness of both the scraper and the angle shovel, thereby improving the long-term effectiveness of the dredging unit.

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0062] It should be noted that the terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0063] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0064] Reference Figure 1 and Figure 3It is known that a quantitative filling and conveying device for solidified soil packaging includes a material distribution hopper 1. The material distribution hopper 1 has a hollow structure inside and is composed of two parts that are snapped together. An assembly unit 2 is provided on one side of the outside of the material distribution hopper 1, a transfer unit 3 is provided inside the material distribution hopper 1, and a sludge removal unit 4 is provided on the other side of the outside of the material distribution hopper 1.

[0065] Reference Figure 1 and Figure 2 It is known that assembly unit 2 includes: a platform 21, which is snapped onto the end of the distribution hopper 1 away from the water storage tank 11; a chassis 22, which is snapped onto the end face of the platform 21 near the distribution hopper 1; two supports 23, which are symmetrically snapped onto the end of the platform 21 away from the chassis 22, and the supports 23 are snapped onto the distribution hopper 1; a three-phase motor 24, which is snapped onto the end of the chassis 22 away from the supports 23; a coupling 25, which is snapped onto the output end of the three-phase motor 24; a three-way valve 26, which is snapped onto the end face of the chassis 22 away from the platform 21 via a mounting bracket, and the three-way valve 26 is inserted into the coupling 25; and a conveying pipe 27, which is snapped onto the other end face of the chassis 22 away from the platform 21 via a mounting bracket, and the conveying pipe 27 is snapped onto the three-way valve 26.

[0066] The specific working process of Assembly Unit 2:

[0067] First, the three-phase motor 24 drives the coupling 25 to rotate. Then, the coupling 25 drives the screw inside the three-way valve 26 (not shown in the figure, but refer to the screw in the screw pump in the prior art) to rotate. When the screw rotates, a certain degree of vacuum is generated inside the pump chamber of the screw pump. Then, the clay is sucked into the pump chamber under the action of vacuum negative pressure. After the clay enters the pump chamber, it is gradually filled into the gap between the spiral groove of the screw and the inner wall of the pump chamber.

[0068] Next, external clay (or other materials that can be used as solidified soil) enters the interior of the three-way valve 26 through the top valve port. Thereafter, as the screw rotates, the clay is subjected to compression and shearing forces in the pump chamber and gradually moves stably along the axis of the three-way valve 26.

[0069] Finally, the conveying pipe 27 guides the clay in the three-way valve 26 into the distribution hopper 1. During this process, when the clay reaches the port of the conveying pipe 27, it is forced out of the pump chamber due to the rotation of the screw.

[0070] Platform 21 and chassis 22: Platform 21 provides a stable working environment for assembly unit 2, transfer unit 3 and sludge removal unit 4, while facilitating the movement of the equipment as a whole by the operator and improving the safety of equipment transfer; chassis 22 provides height compensation for corresponding components in assembly unit 2 (e.g., three-phase motor 24, three-way valve 26 or conveying pipe 27), facilitating rapid assembly between assembly unit 2 and transfer unit 3 or sludge removal unit 4, while providing a certain degree of protection for the aforementioned components and enhancing their service life.

[0071] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 It can be seen that the distribution unit 3 includes: a bridge-type slide rail 31, which is installed inside the distribution hopper 1 with a sliding snap-fit; two support columns 32, which are installed symmetrically with a snap-fit ​​on the horizontal section of the bridge-type slide rail 31; a stiffening plate 33, which is installed with a snap-fit ​​on the end of the two support columns 32 away from the bridge-type slide rail 31; two packing pipes 34, which are installed symmetrically with a snap-fit ​​on both ends of the stiffening plate 33, and both ends of the packing pipes 34 are chamfered; a crossbeam 35, which is installed with a snap-fit ​​on the middle position of the end face of the stiffening plate 33 away from the support column 32; a top plate 36, which is installed with a snap-fit ​​on the middle position of the end face of the crossbeam 35 away from the stiffening plate 33, and has a convex cross-section; and a column 37, which is rotatably installed on the middle position of the end face of the top plate 36 away from the crossbeam 35.

[0072] Reference Figure 4 and Figure 6 It can be seen that two side rails 361 are symmetrically and slidably fitted onto the end face of the top plate 36 away from the crossbeam 35. Each side rail 361 has a rack 362, which is slidably fitted onto one end of the end face away from the top plate 36, and is fitted onto the other side side rail 361. A central shaft gear 363, meshing with the rack 362, is fitted onto the outer wall of the column 37. Connecting plates 364 are fitted onto both ends of the side rails 361 near the top plate 36. A mouth ring 365, which is slidably fitted to the packing tube 34, is snapped onto one end of the mouth ring 364 away from the rack 362. An ear seat 366 is snapped onto the end face of the mouth ring 365 away from the rack 362. A sleeve 367 is snapped onto one of the two ear seats 366 in the same area of ​​the packing tube 34. A guide rod 368, which is slidably fitted to the sleeve 367, is snapped onto the other ear seat 366. A telescopic spring 369 is sleeved on the outer wall of the guide rod 368.

[0073] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6It can be seen that the spring rod 381 is symmetrically embedded and slidably engaged with the end of the rib plate 33 near the mouth ring 365. The ball bearing 382 is engaged with the end of the spring rod 381 near the mouth ring 365. An angle ring 383 is engaged with the end of the mouth ring 365 away from the rack 362, and the diameter of the angle ring 383 is larger than the diameter of the mouth ring 365. An electrode ring 384 is engaged with the end face of the angle ring 383 near the rack 362. A binding ring 385 is symmetrically engaged with the inner wall of the hopper 1. A toothed ring 386 is engaged with the inner wall of the binding ring 385.

[0074] The axial depth of the corner ring 383 is greater than the axial depth of the tie ring 385. The length of the part of the discharge pipe 14 that enters the inner part of the distribution hopper 1 is less than the axial depth of the tie ring 385. The vertical distance between the end face of the corner ring 383 near the rack 362 and the end face of the top plate 36 near the corner ring 383 is greater than the axial depth of the tie ring 385. The vertical distance between the end face of the scraper 413 away from the axis of the crossbar 45 and the axis of the steel ring 46 is equal to the inner radius of the packing tube 34. The vertical distance between the end face of the planetary gear 48 away from the axis of the crossbar 45 and the axis of the steel ring 46 is less than the inner radius of the packing tube 34. In addition, the vertical distance between the end of the support 47 and the vertical bar 411 away from the axis of the crossbar 45 and the axis of the steel ring 46 is also less than the inner radius of the packing tube 34. The lengths of the steel ring 46 and the vertical bar 411 are both greater than the length of the packing tube 34.

[0075] The transposition process of packing tube 34:

[0076] When one of the packing tubes 34 has been in operation for an extended period of time (or when the inner wall of the packing tube 34 needs to be cleaned after an extended period of operation):

[0077] Under the linkage control of the bridge slide rail 31, the support column 32 synchronously causes the stiffening plate 33 to drive the crossbeam 35 to move. In specific implementation, the bridge slide rail 31 can be driven by the electric slider to perform intermittent reciprocating motion under the support and guidance of the material distribution hopper 1 (the intermittent period can be obtained from external experiments as a reference for the extreme working time of a single packing pipe 34 in a harsh environment).

[0078] Subsequently, under the control of the stiffener 33, the position of the packing tube 34 is adjusted variably (i.e., in the initial state, one of the packing tubes 34 is positively connected to both the conveying tube 27 and the discharge tube 14, while the other packing tube 34 is idle. After the first packing tube 34 has been in operation for a specified time, the reciprocating motion of the bridge slide rail 31 is used to adjust the position of the two packing tubes 34 alternately, thereby ensuring the effective flow cross-sectional area between the packing tube 34 and the conveying tube 27 and the discharge tube 14, while balancing the pressure, stabilizing the pressure fluctuation, and improving the alignment accuracy between the packing tube 34 and the conveying tube 27 or the discharge tube 14).

[0079] It is hereby noted that the initial state of the corner ring 383 is not in contact with the inner wall of the distribution hopper 1. That is, the end face of the corner ring 383 near the inner wall of the distribution hopper 1 is a certain distance away from the part of the discharge pipe 14 or the conveying pipe 27 entering the distribution hopper 1, so as to avoid collision and limitation between the packing pipe 34 and the conveying pipe 27 or the discharge pipe 14 when the packing pipe 34 is repositioned.

[0080] The specific process by which the corner rings 383 go from not contacting the inner walls of the same distribution hopper 1 to making contact is as follows:

[0081] First, under the control of the column 37, the central shaft gear 363 simultaneously engages with the racks 362 on both sides. In practice, the column 37 can be rotated by an external motor. After that, the side rails 361 on both sides move in opposite directions or away from each other under the control of the racks 362 (the direction of the opposite direction or away from each other is determined by the direction of the external motor).

[0082] Next, under the synchronous control of the connecting plate 364, the mouth ring 365 moves away from the middle part of the packing tube 34 along the axis of the packing tube 34 (the movement of the mouth ring 365 is also a reciprocating motion; here, we only take the movement of the mouth ring 365 toward the inner wall of the distribution hopper 1 as an example), until the corner ring 383 contacts the inner wall of the distribution hopper 1 (during this process, the packing tube 34 provides stable guiding support to the mouth ring 365, further improving the movement stability of the mouth ring 365, avoiding the influence of external vibration on the single movement accuracy of the corner ring 383, and thus ensuring the alignment accuracy between the corner ring 383 and the conveying pipe 27 or the discharge pipe 14).

[0083] In addition, the inner diameter of the corner ring 383 is larger than the outer diameter of the part of the discharge pipe 14 or the conveying pipe 27 that enters the distribution hopper 1, and the axial depth of the corner ring 383 is greater than the length of the part of the discharge pipe 14 or the conveying pipe 27 that enters the distribution hopper 1. Therefore, when the corner ring 383 comes into contact with the inner wall of the distribution hopper 1, it can completely seal the discharge pipe 14 or the conveying pipe 27, thereby ensuring the stability, continuity and sustainability of clay transportation.

[0084] Finally, the elastic variable of the extension spring 369 itself buffers and degrades the radial or axial runout between the guide rod 368 and the sleeve 367 (the manifestation of external impact during a single movement of the mouth ring 365 or the corner ring 383 will be expressed by the radial or axial runout between the guide rod 368 and the sleeve 367), further improving the alignment accuracy between the packing tube 34 and the conveying tube 27, reducing leakage, and improving conveying accuracy and efficiency;

[0085] For the detection scheme of deformation or displacement variables of mouth ring 365 or corner ring 383:

[0086] When the corner ring 383 moves towards the middle area of ​​the packing tube 34 under the drive of the mouth ring 365, and the ball 382 contacts the electrode ring 384 and maintains a certain interaction force, the external pressure detection and display device provides real-time feedback on the force value between the electrode ring 384 and the ball 382. This helps to determine whether the deformation and displacement of the corner ring 383 or the mouth ring 365 exceed the specified range, which helps to improve the assembly accuracy between the corner ring 383 or the mouth ring 365 and the packing tube 34, thereby improving the stability of clay conveying (in specific implementation, the contact signal between the ball 382 and the electrode ring 384 can be connected to the external pressure display device through an external wire via an electrical connection, and a corresponding alarm device can be configured to remind the operator to inspect the mouth ring 365 or the corner ring 383).

[0087] The purpose of having a greater axial depth for the corner ring 383 than for the binding ring 385, a shorter length for the portion of the discharge pipe 14 entering the distribution hopper 1 than for the binding ring 385, and a greater vertical distance between the end face of the corner ring 383 near the rack 362 and the end face of the top plate 36 near the corner ring 383 than for the binding ring 385 is:

[0088] To prevent the corner ring 383 from failing to move to the designated position during its retraction process due to insufficient space during the movement of the corner ring 383 towards the middle area of ​​the packing tube 34 driven by the mouth ring 365, i.e., when the corner ring 383 is still partially covered by the material conveying pipe 27 or the material discharge pipe 14 entering the distribution hopper 1, the corner ring 383 may have already come into contact with the stiffening plate 33. At this time, when the bridge slide rail 31 moves, the corner ring 383 moves synchronously. During this process, the corner ring 383 will collide with the material discharge pipe 14 or the material conveying pipe 27, which may limit its movement or even affect the normal repositioning of the packing tube 34.

[0089] Reference Figure 8 and Figure 9 It can be seen that the dredging unit 4 includes: two corner frames 41, which are symmetrically installed on the outer wall of the distribution hopper 1 away from the conveying pipe 27; a rail 42, which is installed in the middle of the horizontal section of the corner frame 41; a telescopic cylinder 43, which is installed at the end of the horizontal section of the corner frame 41 away from the distribution hopper 1; and an empty shelf 44, which is installed in the horizontal section of the corner frame 41 with a sliding snap-fit, and the empty shelf 44 is installed in a snap-fit ​​with the movable end of the telescopic cylinder 43.

[0090] A crossbar 45 is snap-fitted and installed in the middle of the empty shelf 44; a steel ring 46 is snap-fitted and installed on the outer wall of the crossbar 45; three brackets 47 are snap-fitted and installed at both ends of the outer wall of the steel ring 46, with two brackets 47 distributed at one end of the steel ring 46 near the telescopic cylinder 43 and one bracket 47 distributed at the other end; a planetary gear 48 is rotatably installed between the two brackets 47 at the end near the telescopic cylinder 43 via a rotating shaft.

[0091] Reference Figure 8 and Figure 9 It can be seen that a vertical rod 411 is installed between the two supports 47 at both ends in a rotating fit. The outer wall of the vertical rod 411 is provided with a snake mouth groove 412. A scraper 413 is installed on the outer wall of the steel ring 46. The scraper 413 is chamfered at the end away from the axis of the steel ring 46. Two corner shovels 414 are installed on the outer wall of the scraper 413 in a sliding fit with the steel ring 46. In addition, the vertical distance between the two corner shovels 414 is at least five centimeters. An angle plate 415 is installed on the end of the two corner shovels 414 away from the axis of the steel ring 46 in a joint fit. A matching plate 416 is installed on the end face of the angle plate 415 near the vertical rod 411. A steel ball 417 that matches the snake mouth groove 412 is installed on the end of the matching plate 416 near the vertical rod 411 in a rotating fit.

[0092] Reference Figure 1 and Figure 2 It can be seen that a water storage tank 11 is installed on the outer wall of the end of the material distribution hopper 1 near the rack 362 by a mounting seat. A water guide pipe 12 is inserted and installed on the end of the water storage tank 11 away from the rack 386. A spray pipe 13 is installed and installed at the water outlet end of the water guide pipe 12. A discharge pipe 14 is inserted and installed at the middle position of the end face of the material distribution pipe away from the water guide pipe 12. A water outlet pipe 15 is symmetrically inserted and installed on the end face of the material distribution hopper 1 away from the discharge pipe 14.

[0093] The cleaning process for the deposited or solidified clay on the inner wall of the packing tube 34 (in its idle state):

[0094] First, the empty shelf 44 is pushed by the telescopic cylinder 43 and moves towards the distribution hopper 1 under the support and guidance of the rail 42 until the gear ring 386 meshes with the planetary gear 48 in the positive direction. Then, the steel ring 46 is driven to rotate by the crossbar 45. During the rotation process, the steel ring 46 continuously controls the meshing motion between the planetary gear 48 and the gear ring 386. In specific implementation, the crossbar 45 can be driven to rotate by the built-in motor, and the built-in motor can be placed in the middle area of ​​the empty shelf 44.

[0095] Next, the scraper 413, which is rotating during the process, is used to scrape away the clay deposited or solidified in the inner wall of the packing tube 34. (The purpose of chamfering the scraper 413 and the working end of the packing tube 34 is to reduce the contact area between the scraper 413 and the inner wall of the packing tube 34, thereby reducing the friction between the two and improving the scraping effect of the scraper 413 on the inner wall of the packing tube 34.)

[0096] Finally, as the vertical rod 411, synchronously controlled by the planetary gear 48, rotates, the snake-mouth groove 412 continuously moves in relation to the steel ball 417. During this process, the positioning plate 416, under the control of the steel ball 417, synchronously drives the corner plate 415 to move. This allows the corner plate 415 to control the corner shovel 414, which is a distance away, to reciprocate along the axis of the crossbar 45 under the combined guidance of the scraper 413 and the steel ring 46 (the reciprocating motion is determined by the direction of the crossbar 45 – the direction of the steel ring 46 and the crossbar 45 is synchronous). This results in the scraper 413 rotating while the corner shovel 414 scrapes the scraper 413, ensuring the cleanliness of the scraper 413 and the corner shovel 414 (reducing the redeposition rate of clay on the end face of the scraper 413), thereby improving the long-term effectiveness of the dredging unit 4.

[0097] External components assist the dredging unit 4 in the following processes:

[0098] When scraper 413 cleans the inner wall of packing tube 34:

[0099] First, the cleaning liquid stored inside the water tank 11 is directed to the area of ​​the spray pipe 13 through the water guide pipe 12. In specific implementation, the cleaning liquid in the water tank 11 can be directed to the area of ​​the spray pipe 13 through the water guide pipe 12 by an external pressure pump.

[0100] Next, cleaning fluid is evenly sprayed onto the working area of ​​scraper 413 through spray pipe 13 to assist scraper 413 in cleaning the inner wall of packing tube 34 and further enhance the cleaning effect of scraper 413 on the clay in the inner wall of packing tube 34.

[0101] Finally, the wastewater inside the distribution hopper 1 is directed to the outside through the outlet pipe 15 by an external pressure pump.

[0102] The working principle of the quantitative filling and conveying device for solidified soil packaging provided by the present invention is as follows: First step: First, the support column 32 moves synchronously with the rib plate 33 under the control of the bridge slide rail 31 until the positions of the filling pipe 34 and the conveying pipe 27 are interchanged at different positions. Then, the rack 362 is controlled by the central shaft gear 363 to drive the mouth ring 365 to move in opposite directions or away from each other under the guidance of the filling pipe 34 until the ball 382 is tangent to the electrode ring 384.

[0103] Step 2: Next, the telescopic cylinder 43 drives the empty shelf 44 under the guidance of the strip plate, causing the crossbar 45 to drive the steel ring 46 to move into the packing tube 34 until the scraper 413 fully covers the inner wall of the packing tube 34 in the axial direction. After that, the crossbar 45 drives the steel ring 46 to rotate. During this process, through the meshing between the planetary gear 48 and the gear ring 386, the vertical bar 411 rotates at a speed different from that of the crossbar 45.

[0104] Step 3: Finally, through the interaction between the snake mouth groove 412 and the steel ball 417, the steel ball 417 synchronously controls the positioning plate 416 to drive the corner plate 415 to move. After that, under the combined guidance of the steel ring 46 and the scraper 413, the corner shovel 414 synchronously follows the corner plate 415 to reciprocate along the axis of the crossbar 45. At the same time, the cleaning liquid stored in the water tank 11 is gradually guided to the spray pipe 13 through the water guide pipe 12, so as to cooperate with the scraper 413 to clean the inner wall of the packing tube 34, thereby improving the cleaning effect and cleaning ability.
