DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts, fall within the scope of protection of the present application.

[0039] EMBODIMENT

[0040] An embodiment of the first aspect of this application provides a hopper that can be used for a grout spreading terminal and a grout spreading device. The grout spreading terminal can perform grout dispensing, grout storage, and grout spreading; the grout spreading device is equipped with a traveling mechanism, on which the grout spreading terminal is mounted, and the traveling mechanism can drive the grout spreading terminal to the area to be paved to spread the grout. The grout can be tile adhesive or other grout used for laying floor tiles, and the grout spreading terminal can be used for laying tile adhesive in floor tile laying.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, as a slurry distribution and storage component of the slurry spreading terminal 1000, the hopper 100 of this application has a slurry spreading chamber 10. The slurry spreading chamber 10 is used to receive the slurry pumped in by the slurry pumping equipment and to evenly distribute the pumped slurry to the bottom for the scraper 300 of the slurry spreading terminal 1000 to spread the slurry.

[0042] The slurry-spreading chamber 10 is an elongated cavity extending in the left-right direction. In this embodiment, for ease of explanation, refer to... Figure 3 and Figure 4 ,exist Figure 1 In the diagram, the length direction of the slurry spreading chamber 10 is taken as the left-right direction, and the width direction of the slurry spreading chamber 10 is taken as the front-back direction. A scraper 300 for scraping slurry is installed on the front or rear side of the slurry spreading chamber 10. The scraper 300 is also arranged along the length direction of the slurry spreading chamber 10, so that the slurry spreading terminal 1000 in this embodiment is... Figure 1 The slurry spreading operation is performed by moving the slurry in the forward and backward directions. In other embodiments, the aforementioned relative directions of forward, backward, left, and right can also be reversed accordingly.

[0043] The slurry spreading chamber 10 is provided with slurry distribution blocks 14 extending in the left and right direction. The upper end of the slurry spreading chamber 10 is provided with a slurry inlet 13, which is located above the slurry distribution blocks 14 and is used to pump in slurry. The lower end of the slurry spreading chamber 10 is provided with a slurry outlet 16, which is located below the slurry distribution blocks 14 and is used to supply slurry to flow out to the bottom of the slurry spreading terminal 1000.

[0044] like Figure 3 As shown, a horizontal first sub-slurry distribution channel A is formed between the upper surface of the slurry distribution block 14 and the inner upper wall of the slurry spreading chamber 10. The first sub-slurry distribution channel A is connected to the slurry inlet 13. After the slurry enters the first sub-slurry distribution channel A from the slurry inlet 13, it can flow to the left and right sides of the slurry spreading chamber 10 under the action of the fluid's own gravity and / or external pressure, so as to prevent the slurry from accumulating at the slurry inlet 13 and causing solidification.

[0045] Optionally, in the embodiment of the present application, the pulp inlet 13 is arranged at the middle of the left-right direction of the pulp laying bin 10, so that the first sub-pulp distribution channels A are uniformly distributed on both sides of the bottom of the pulp inlet 13, the pipe pressure of the first sub-pulp distribution channels A on both sides is the same, so that the flow rate of the pulp is also the same, and the pulp distribution is more uniform. In other examples, the pulp inlet 13 can also be arranged on the left or right side.

[0046] As shown in Figure 3 , the first sub-pulp distribution channels A are located on both sides of the left-right direction below the pulp inlet 13 and are in communication with the pulp inlet 13 to form a T-shaped channel, which helps the pulp to flow from the pulp inlet 13 to both sides of the first sub-pulp distribution channels A after entering, preventing the pulp from accumulating in the middle of the pulp distribution block 14 and causing the pulp to flow out.

[0047] As shown in Figure 2 and Figure 3 , a plurality of pulp distribution holes 141 are arranged on the pulp distribution block 14 along the left-right direction, which are used for the pulp to flow out of the first sub-pulp distribution channels A in the vertical direction. Among them, the pulp distribution holes 141 can be uniformly distributed along the left-right direction, or can be distributed in a more dense manner along the left and right sides, that is, the farther to the middle of the pulp distribution block 14, the greater the distance between adjacent two pulp distribution holes 141, and the farther to the left and right directions of the pulp distribution block 14, the smaller the distance between adjacent two pulp distribution holes 141. In addition, the size of the pulp distribution hole in the embodiment is not limited, and the size of the pulp distribution hole can be set according to the properties of the pulp.

[0048] The left and right ends of the pulp distribution block 14 and the inner walls of the left and right sides of the pulp laying bin 10 form downward pulp distribution ports C. The second sub-pulp distribution channels B are formed between the pulp distribution ports C and the first sub-pulp distribution channels A, and the second sub-pulp distribution channels B are inclined downward and make the pulp distribution ports C and the first sub-pulp distribution channels A communicate with each other.

[0049] In the embodiment of the present application, the left and right sides of the pulp distribution block 14 and the inner walls of the pulp laying bin 10 form the second sub-pulp distribution channels B, the inlets of the second sub-pulp distribution channels B are in communication with the horizontally arranged first sub-pulp distribution channels A, and the outlets are in communication with the downward pulp distribution ports C, so the second sub-pulp distribution channels B are inclined downward. Among them, the inclined downward surface can be formed on the left and right sides of the pulp distribution block 14, or the inner walls of the corresponding pulp laying bin 10 on the left and right sides of the pulp distribution block 14 are inclined downward, or as shown in the example of Figure 2 , Figure 3 , the left and right sides of the pulp distribution block 14 and the inner walls of the corresponding pulp laying bin 10 form inclined downward surfaces.

[0050] The second sub-slurry flow channel can be uniformly inclined downward from horizontal with a certain radian, or can be inclined downward according to the shape of the left and right sides of the slurry distribution block 14 and the corresponding shape of the inner wall of the corresponding slurry laying bin 10.

[0051] In the process of laying the slurry, when encountering uneven ground (this situation is likely to occur at the slurry laying position near the wall), the slurry laying height needs to be ensured to be consistent. When the slurry of the previous brick is laid, the part of the ground that is depressed will have a higher slurry laying height. When the next brick is laid, the corresponding slurry position may not be sufficient, resulting in a lack of slurry. According to the traditional hopper structure, the probability of a lack of slurry on the left and right sides is relatively high, which can cause hollowing during brick laying. In addition, during the first use of the pump slurry process, the phenomenon of lack of material on the left and right corner parts is also likely to occur. In the embodiment of the present application, after the slurry enters the slurry laying bin 10 from the slurry inlet 13, it flows horizontally along the first sub-slurry flow channel A to the left and right sides under the action of its own gravity and external pressure. At this time, part of the slurry will flow out from the slurry distribution hole 141 on the slurry distribution block 14, and part of the slurry will continue to flow along the first sub-slurry flow channel A to the left and right sides of the slurry distribution block 14, and finally flow out from the second sub-slurry flow channel B and the slurry distribution port C. This solves the problem of lack of material on the corner part during the first use in the traditional technology, and in the case of uneven ground, it can ensure that the left and right sides of the slurry are sufficient, making the laying of the ceramic tile more stable. At the same time, the setting of the second sub-slurry flow channel B which is inclined downward not only ensures that the slurry in the first sub-slurry flow channel A has enough fluid pressure, so that the slurry can flow out smoothly from the slurry distribution hole 141, but also quickly releases the fluid pressure of the horizontally moving slurry through the inclined downward flow guide, so that the slurry on both sides can also flow downward smoothly and quickly.

[0052] In addition, the hopper in the traditional technology has a slurry distribution chamber and a slurry storage chamber that are sequentially connected from top to bottom independently of each other. A through hole is formed in the bottom wall of the slurry distribution chamber, and the slurry storage chamber and the slurry distribution chamber are only connected through the through hole in the bottom wall of the slurry distribution chamber. When hard blocks are mixed in the slurry, the slurry is easy to block in the through hole, causing poor slurry discharge, which leads to a lack of slurry. The structural design of the slurry laying bin 10 in the embodiment of the present application is provided with a plurality of slurry distribution holes 141 on the slurry distribution block 14, and a slurry distribution port C is further provided between the left and right ends of the slurry distribution block 14 and the left and right inner walls of the slurry laying bin 10. This not only allows the slurry to flow out from the slurry distribution holes 141, but also allows the slurry to flow out from the slurry distribution ports C on both sides of the slurry distribution block 14, thereby preventing the slurry from accumulating in the first sub-slurry flow channel A. Further, the diameter of the slurry distribution port C is larger than the diameter of the slurry distribution hole 141. Even if there is hard slurry in the slurry with a diameter larger than that of the slurry distribution hole 141, it can also be guided out from the slurry distribution ports C on both sides of the slurry distribution block 14, thereby preventing the slurry from being blocked in the slurry distribution hole 141, and the slurry discharge is smoother.

[0053] Structurally, the hoppers in related technologies are designed with independent slurry distribution chambers and slurry storage chambers, which are relatively complex, more difficult to process, and have many dead corners on the inner wall that are not easy to clean. In contrast, the hopper in this embodiment is an integral slurry spreading chamber 10, which has a simpler structure, is easier to process, and does not have dead corners on the inner wall that are difficult to clean.

[0054] The bottom wall structure of the slurry distribution chamber in related technologies has design flaws, leading to slurry stagnation or backflow, which in turn causes slurry solidification. The slurry spreading chamber 10 of this application has a slurry dispensing port C between the left and right ends of the slurry dispensing block 14 and the inner walls of the left and right sides of the spreading chamber 10, with the dispensing port C facing downwards. Therefore, the slurry can flow out smoothly from the dispensing port C, allowing for rapid pressure relief and preventing slurry stagnation or backflow that could lead to solidification. Furthermore, after flowing out from the dispensing port C, the slurry passes through the lower uniform mixing chamber 20 and reaches the edges of the area to be paved, preventing slurry shortages on both sides and reducing the problem of voids.

[0055] like Figure 2 and Figure 3 As shown, in this embodiment, the slurry distribution block 14 is integrally molded, which reduces the number of parts and simplifies assembly and disassembly. In other embodiments, the slurry distribution block 14 can be formed by splicing together multiple sub-slurry distribution blocks 14, which facilitates storage and transportation after disassembly. The slurry distribution block 14 can be made of aluminum profile material or other materials.

[0056] In a preferred embodiment, the cross-sectional area of ​​the first sub-slurry channel A is V2, and the cross-sectional area of ​​the slurry inlet 13 is V1. The following relationship exists between V2 and V1: 1 / 2 * V1 <V2<V1。

[0057] It should be noted that: the cross-sectional area V2 of the first sub-slurry channel A is the cross-sectional area visible along the height direction when the first sub-slurry channel A is cut along the height direction of the slurry spreading chamber 10. The cross-sectional area V1 of the slurry inlet 13 is the cross-sectional area visible along the horizontal direction when the slurry inlet 13 is cut along the width direction of the slurry spreading chamber 10.

[0058] In the flow channel design, if the radius of the flow channel is too large, no pressure will be formed to push the slurry to the two sides, and the slurry cannot flow to the two sides of the first sub-slurry distribution channel A; if the radius of the flow channel is too small, the pressure will be large, the surface of the slurry laying bin 10 will be stressed, and the small-pore slurry distribution holes 141 are prone to water droplet effect, and the slurry will still flow from the middle, less on both sides, resulting in lack of slurry in the two side regions. Therefore, in the flow channel design in the embodiment, the cross-sectional area V2 of the first sub-slurry distribution channel A is greater than half of the cross-sectional area V1 of the slurry inlet 13 and less than the cross-sectional area V1 of the slurry inlet 13, so that the slurry has a certain "pipeline" pressure during the lateral movement in the first sub-slurry distribution channel A, forcing the slurry to flow down from the slurry distribution holes 141 on the slurry distribution block 14; at the same time, the slurry can quickly and uniformly flow to the left and right ends of the slurry distribution block 14 within a limited height, preventing lack of slurry on both sides; further, the height of the slurry laying bin 10 can be made smaller, the overall volume is smaller, the material is less, the cost is saved, and the weight is reduced.

[0059] The cross-sectional area of the second sub-slurry distribution channel B is not limited in the embodiment of the application. Optionally, the cross-sectional area of the second sub-slurry distribution channel B is V3, V3≧V2; and V3 gradually increases along the downward direction of the inclination. The cross-sectional area V3 of the second sub-slurry distribution channel B is the cross-sectional area that can be seen when the second sub-slurry distribution channel B is cut along the radial direction.

[0060] The cross-sectional area V3 of the second sub-slurry distribution channel B is greater than or equal to the cross-sectional area V2 of the first sub-slurry distribution channel A, that is, the pipeline diameter of the second sub-slurry distribution channel B and the pipeline diameter of the first sub-slurry distribution channel A can be effectively matched, so that the slurry fills the moving space during lateral movement and generates a certain pressure to quickly push the slurry to the slurry distribution hole; the second sub-slurry distribution channel B is inclined downward to achieve the purpose of pressure relief, which helps the slurry to quickly flow down from the slurry distribution hole C.

[0061] In a preferred embodiment, the left and right sides of the slurry distribution block 14 respectively form first inclined portions inclined to the two sides and downward, the inner wall of the slurry laying bin 10 corresponds to the first inclined portions to form second inclined portions inclined to the two sides and downward, and the first inclined portions and the second inclined portions enclose the second sub-slurry distribution channel B.

[0062] The cross-sectional area of ​​the second sub-slurry channel B is V3. The cross-sectional area at the inlet of the second sub-slurry channel B is the same as the cross-sectional area V2 of the first sub-slurry channel A. The cross-sectional area at the outlet of the second sub-slurry channel B is larger than the cross-sectional area V2 of the first sub-slurry channel A. The cross-sectional area of ​​the second sub-slurry channel gradually increases along the downward slope of the second sub-slurry channel B. This causes the slurry at the front to gradually accelerate its movement speed under the combined influence of gravity and the expansion of the movement space when the slurry flows out. The expansion of the space also causes gaps to form between the slurries with different movement speeds at the front and rear. These gaps can create a certain negative pressure in the middle of the second sub-slurry channel. This negative pressure can exert a suction force on the slurry moving backward, increasing the flow speed of the slurry to both sides.

[0063] The length of the second sub-slurry channel B is the length between the inlet and outlet of the second sub-slurry channel B.

[0064] The length of the second sub-slurry distribution channel B is not limited in this embodiment. Optionally, the length of the second sub-slurry distribution channel B can be set according to the slurry discharge requirements and slurry discharge efficiency. The second sub-slurry distribution channel B is set with a certain length, which can accelerate the discharge of slurry in the second sub-slurry distribution channel B; and form a certain degree of pressure relief channel with the first sub-slurry distribution channel A, forming a certain fluid suction force on the slurry in the first sub-slurry distribution channel A, thereby accelerating the flow rate of the slurry in the first sub-slurry distribution channel A and reducing accumulation or residue.

[0065] Optionally, an inclined surface is provided between the upper surface of the slurry distribution block 14 and its left and right ends, so that the slurry distribution block 14 and the inner walls of the left and right sides of the slurry spreading chamber 10 form a downward inclined second sub-slurry distribution channel B. If the inclination angle of the second sub-slurry distribution channel B is too large, the pressure relief capacity will be large, and the slurry flow rate will be difficult to control; if the inclination angle of the second sub-slurry distribution channel B is too small, the pressure relief capacity will be small, and the slurry flow rate will be slow, which will affect the slurry spreading efficiency. Therefore, the angle between the upper surface of the slurry distribution block 14 and the inclined surface, that is, the inclination angle of the second sub-slurry distribution channel B, can be set according to the slurry discharge requirements.

[0066] The embodiments of this application do not limit the upper surface structure of the slurry block 14. Optionally, such as Figure 4 As shown, the bottom of the first sub-slurry channel A can be arc-shaped, which helps the slurry flow. The upper surface of the slurry block 14 forms an arc-shaped groove structure extending in the left and right direction. The slurry hole 141 is set at the bottom of the arc-shaped groove structure, which can better discharge the material and reduce slurry residue.

[0067] Further, the slurry distribution port C, the second sub-slurry distribution channel B, and the first sub-slurry distribution channel A are in communication with each other to form a slurry distribution channel with a siphon effect, and the cross-sectional areas of the slurry distribution port C, the second sub-slurry distribution channel B, and the first sub-slurry distribution channel A are matched with each other, the bottom of the first sub-slurry distribution channel A is arc-shaped, which can make the overall slurry distribution channel have a stronger siphon effect, and the slurry has a faster flow speed in each section of the slurry distribution channel, so that the cross-sectional area of each section of the slurry distribution channel can be designed to be smaller under the condition that the width of each section of the slurry distribution channel is fixed, thereby making the height of the hopper smaller.

[0068] As shown in Figure 1 and Figure 2 The hopper 100 of the embodiment of the application comprises a front cover plate 11 and a rear cover plate 12, and the front cover plate 11 and the rear cover plate 12 are covered with each other to form a slurry paving bin 10.

[0069] Optionally, the slurry inlet 13 is detachably mounted on the front cover plate 11, or the slurry inlet 13 is detachably mounted on the rear cover plate 12.

[0070] Preferably, the front cover plate 11 and the rear cover plate 12 are detachably covered with each other to form the slurry paving bin 10. Specifically, the front cover plate 11 and the rear cover plate 12 can be buckled with each other through buckling members, or connected through fasteners, to achieve detachable covering.

[0071] The detachable covering of the front cover plate 11 and the rear cover plate 12 is beneficial to the disassembly and transportation of the hopper 100. For example, when it is necessary to pave tiles on a floor without an elevator, the whole machine is not convenient to transport, and the hopper 100 can be quickly disassembled into multiple parts, and each part is transported to the target floor for assembly and use; in addition, when a certain part of the hopper 100 is damaged, the hopper can be quickly disassembled to facilitate replacement of the damaged part, which has strong versatility. At the same time, after the construction is completed, the front cover plate 11 and / or the rear cover plate 12 of the hopper 100 can be disassembled to completely open the slurry paving bin 10, so as to facilitate cleaning. Compared with the cleaning of the slurry distribution bin through a small hole in the prior art, the detachable cleaning method of the embodiment is easier to operate, and the slurry paving bin 10 can be quickly cleaned, and there is no slurry residue in the dead angle.

[0072] Optionally, the front cover plate 11 and the rear cover plate 12 of the hopper 100 can be made of aluminum profiles. The aluminum profile is an alloy material with aluminum as the main component. The aluminum rod is heated and extruded to obtain aluminum materials with different cross-sectional shapes. The aluminum profile is light in weight, and the use of aluminum profile to make the hopper 100 helps to reduce the overall weight of the paving terminal 1000 and facilitates transportation. In addition, the surface of the aluminum profile has the characteristics of dirt resistance and easy cleaning after oxidation. Therefore, the use of aluminum profile to make the hopper 100 helps to reduce the cleaning difficulty of the paving terminal 1000, saves the cleaning time after paving, and reduces the cleaning cost.

[0073] Optionally, the front cover plate 11 and the rear cover plate 12 of the hopper 100 can also be made of aluminum alloy materials or other materials.

[0074] In an optional embodiment, as shown in Figure 3 The sealing groove 111 is provided at the fastening position of the front cover plate 11 and the rear cover plate 12. Figure 5 and Figure 6 The sealing strip 15 is provided in the sealing groove 111. The sealing strip 15 can enhance the sealing performance of the front cover plate 11 and the rear cover plate 12 when they are closed, and prevent the slurry from leaking from the connection position of the two cover plates during the paving process. After the construction is completed, the sealing strip 15 can be removed from the sealing groove 111 for quick cleaning. Optionally, the sealing groove 111 can be provided on the front cover plate 11 or on the rear cover plate 12.

[0075] Optionally, the sealing strip 15 can be made of silica gel material, and the width can be between 20 mm and 30 mm, which has better sealing effect.

[0076] The embodiments of the present application do not limit the way in which the slurry dividing block 14 is fixed to the rear cover plate 12. Optionally, the slurry dividing block 14 can be detachably installed on the inner wall of the front cover plate 11. The slurry dividing block 14 can be installed on the front cover plate 11 by screws, or by hanging, or by other ways.

[0077] In other embodiments, the slurry dividing block 14 can be detachably installed on the inner wall of the rear cover plate 12, for example, the slurry dividing block 14 can be installed on the inner wall of the rear cover plate 12 by screws, or by hanging, or by other ways.

[0078] In an optional embodiment, as shown in Figure 4As shown, the inner wall of the front cover plate 11 includes an upper straight section inner wall 112 and a lower arc-shaped section inner wall 113, while the inner wall of the rear cover plate 12 can be vertically arranged. The arc-shaped section inner wall 112 causes the cross-sectional area of ​​the slurry filling chamber 10 to gradually decrease from top to bottom, forming a pressure chamber that is larger at the top and smaller at the bottom, which helps the slurry to flow out quickly.

[0079] In other alternative embodiments, such as Figure 8 As shown, the inner wall of the rear cover plate 12 includes an upper straight section and a lower arc-shaped section, while the front cover plate 11 can be a vertical cover plate. The arc-shaped section causes the cross-sectional area of ​​the slurry dispensing chamber 10 to gradually decrease from top to bottom, forming a pressure chamber that is larger at the top and smaller at the bottom, which helps the slurry to flow out quickly.

[0080] In other alternative embodiments, both the front cover plate 11 and the rear cover plate 12 include an upper straight section inner wall and a lower arc-shaped section inner wall. The front cover plate 11 and the rear cover plate 12 cover each other. The arc-shaped section inner wall on the two cover plates causes the cross-sectional area of ​​the slurry spreading chamber 10 to gradually decrease from top to bottom, forming a pressure chamber that is larger at the top and smaller at the bottom, which helps the slurry to flow out quickly and improves the slurry spreading efficiency.

[0081] In an alternative embodiment, such as Figure 4 As shown, the arc-shaped section of the inner wall of the front cover plate 11 extends to the side wall of the first sub-slurry channel A. That is, the side wall of the first sub-slurry channel A includes both a straight section and an arc-shaped section, thus forming a small pressure chamber at the first sub-slurry channel A. This facilitates rapid slurry flow and prevents slurry solidification within the first sub-slurry channel A. Furthermore, the bottom wall of the first sub-slurry channel A is arc-shaped. The arc-shaped side wall and the arc-shaped bottom wall of the first sub-slurry channel A can form a continuous arc-shaped inner wall, thereby further increasing the pipe pressure within the first sub-slurry channel A, forcing the slurry to flow faster to prevent solidification, and improving slurry spreading efficiency.

[0082] The technical solution in the above embodiments of this application, by setting grout distribution blocks extending on the left and right sides along the grouting direction in the grouting hopper, and the upper surface of the grout distribution blocks forming a horizontal first sub-grouting channel with the inner wall of the grouting hopper, and the left and right sides of the grout distribution blocks forming a downward inclined second sub-grouting channel with the inner wall of the grouting hopper, allows the grouting holes set on the grout distribution blocks to allow the grout in the first sub-grouting channel to flow evenly to the bottom of the grout distribution block, while the grout flowing from the first sub-grouting channel to the sides of the grout distribution block can flow out from the grouting port along the downward inclined second sub-grouting channel, thereby avoiding clogging of the grouting holes during the grouting flow. During the grouting flow, the grout flows out from the downward-facing second sub-grouting channel at both ends of the grout distribution block, which can prevent the tile adhesive from solidifying in the hopper, solving the problem of tile adhesive solidification caused by the presence of non-flowing and backflow areas in the hopper in related technologies; and solving the problem of insufficient grout on both sides and corners during grouting, which helps to improve the overall grouting quality and tile laying quality.

[0083] Meanwhile, the first sub-pulp flow channel between the upper surface of the pulp distribution block and the upper wall of the pulp laying bin has a cross-sectional area smaller than that of the pulp inlet and greater than 1 / 2 of the cross-sectional area of the pulp inlet, so that the pulp has a certain pipeline pressure during the lateral movement of the first sub-pulp flow channel by a certain distance, so that the pulp can flow down quickly and uniformly from the pulp distribution holes on the pulp distribution block, the height of the pulp laying bin can be reduced, the weight of the hopper can be reduced, and the cost can be saved.

[0084] In addition, the bottom side wall of the first sub-pulp flow channel is formed as an arc segment through the front cover plate or the rear cover plate, and the upper surface of the pulp distribution block is formed as a groove structure, which can further increase the pipeline pressure of the first sub-pulp flow channel and make the pulp flow down quickly and uniformly from the pulp distribution holes on the pulp distribution block.

[0085] The second aspect of the present application provides a pulp laying terminal. As shown in Figure 4 and Figure 7 The pulp laying terminal 1000 includes a feeding shaft 200 and a hopper 100 provided by the first aspect. Optionally, as shown in Figure 4 The hopper 100 further has a pulp uniformizing chamber 20 located at the rear side of the pulp laying bin 10 and communicating with the pulp outlet 16 of the pulp laying bin 10. The pulp outlet flow channel formed at the pulp outlet 16 is perpendicular to the laying surface, which can reduce the amount of air trapped between the pulp and the ground, improve the adhesion of the pulp to the ground, and prevent the ceramic tile from being empty after installation.

[0086] The feeding shaft 200 is installed in the pulp uniformizing chamber 20 and arranged in the left-right direction. The feeding shaft 200 is a spiral feeding shaft. The spiral feeding shaft is configured to rotate, for example, forward or reverse, so that the pulp in the pulp uniformizing chamber 20 is fed in a predetermined direction and uniformly dispersed in the pulp uniformizing chamber 20, so that the pulp is uniformly distributed in the pulp uniformizing chamber 20. When the pulp in the pulp uniformizing chamber 20 flows out of the pulp outlet 16 to the pulp laying surface, it is beneficial to uniformly lay the pulp on the ground, improve the uniformity of the pulp laying, avoid the problem of empty ceramic tile when manually laying the pulp, and further improve the quality of the tile laying.

[0087] The feeding port of the pulp uniformizing chamber 20 is configured as a long strip-shaped opening extending along the width direction of the pulp laying terminal 1000. Through this arrangement, the pulp is uniformly fed in the width direction during the feeding into the pulp uniformizing chamber 20, which is beneficial to ensure the uniform distribution of the pulp in the pulp uniformizing chamber 20 under the action of the spiral feeding shaft, thereby ensuring the uniformity of the pulp flowing out of the discharge port of the pulp uniformizing chamber 20 and improving the quality of the pulp laying.

[0088] As shown in Figure 4As shown, the homogenizing chamber 20 is arranged at the rear side of the paving bin 10, so that the operator can check the slurry condition in the homogenizing chamber 20 in time during the paving process. The slurry outlet flow channel formed at the slurry outlet 16 is perpendicular to the paving surface, which can reduce the amount of air trapped between the slurry and the ground, improve the adhesion of the slurry to the ground, and prevent the ceramic tile from being hollow after installation.

[0089] In an optional embodiment, the paving terminal 1000 further comprises a scraper 300 provided with scraping teeth. During the paving process, the paving terminal 1000 is moved by the walking mechanism, and the scraper 300 is driven to scrape the slurry on the paving surface to make the paving height uniform and reduce the problem of air pockets in the manual paving process.

[0090] Optionally, the homogenizing chamber 20 is an elongated chamber extending in the left-right direction, and the width of the scraper 300 is consistent with the width of the homogenizing chamber 20, so that the slurry can be better pushed to the two sides of the paving surface to ensure full slurry and uniformity, prevent lack of slurry on the two sides, and reduce the problem of air pockets.

[0091] Optionally, the homogenizing chamber 20 is located at the rear side of the rear cover plate 12, so as to facilitate the operator to observe the slurry stock in the homogenizing chamber 20 and better control the paving of the paving terminal 1000.

[0092] Optionally, the scraper 300 and the front cover plate 11 are integrally formed, which can facilitate the disassembly and cleaning of the scraper 300. To avoid damage to the scraper 300 during cleaning of the paving bin 10, the scraper 300 can be disassembled before cleaning the paving bin 10.

[0093] In another embodiment, as shown in Figure 8 the homogenizing chamber 20 is located at the front side of the front cover plate 11, so as to facilitate the operator to observe the slurry stock in the homogenizing chamber 20 and better control the paving of the paving terminal 1000. At this time, the scraper 300 is detachably mounted on the side wall of the homogenizing chamber 20. The front cover plate 11 is vertically arranged, and the rear cover plate 12 has a straight line segment inner wall and an arc segment inner wall connected in the up-down direction. The front cover plate 11 and the rear cover plate 12 are overlapped to form a pressurizing chamber. The pressurizing effect of the pressurizing chamber is beneficial to ensure that the slurry pressure flowing out of the slurry outlet 16 meets the paving operation requirements.

[0094] The third aspect of the present application provides a paving device, which comprises a walking mechanism (not shown) and the paving terminal provided in the second aspect. The paving terminal is mounted on the walking mechanism. The walking mechanism can be a mobile trolley.

[0095] Optionally, the paving mechanism can be mounted on the walking mechanism through a rack. The paving device provided in the present application can drive the paving terminal to move and pave during the walking process of the walking mechanism.
