As shown in fig. 1, 2 and 4, in one embodiment, as a slurry-separating and storing part of the slurry-spreading terminal 1000, the hopper 100 of the present application has a slurry-spreading bin 10, and the slurry-spreading bin 10 is used for receiving slurry pumped by a slurry-pumping device and uniformly distributing the pumped slurry to the bottom for spreading by the scraper 300 of the slurry-spreading terminal 1000.

In this embodiment, referring to fig. 3 and 4, in the illustration of fig. 1, the longitudinal direction of the slurry spreading bin 10 is taken as the left-right direction, the width direction of the slurry spreading bin 10 is taken as the front-rear direction, and a scraper 300 for scraping slurry is mounted on the front side or the rear side of the slurry spreading bin 10, and the scraper 300 is also disposed along the longitudinal direction of the slurry spreading bin 10, so that the slurry spreading terminal 1000 of this embodiment performs slurry spreading operation by moving in the front-rear direction of fig. 1. In other embodiments, the above-mentioned front-back, left-right and opposite directions can be described in a corresponding manner.

The slurry spreading bin 10 is provided therein with a slurry dividing block 14 extending in the left-right direction. The upper end of the slurry spreading bin 10 is provided with a slurry inlet 13, and the slurry inlet 13 is positioned above the slurry dividing block 14 and is used for pumping slurry; the lower end of the slurry spreading bin 10 is provided with a slurry outlet 16, and the slurry outlet 16 is positioned below the slurry dividing block 14 and is used for supplying slurry to flow out to the bottom of the slurry spreading terminal 1000.

As shown in fig. 3, a horizontal first sub-slurry flow channel a is formed between the upper surface of the slurry dividing block 14 and the inner upper wall of the slurry spreading bin 10, the first sub-slurry flow channel a is communicated with the slurry inlet 13, and after the slurry enters the first sub-slurry flow channel a from the slurry inlet 13, the slurry can flow to the left and right sides of the slurry spreading bin 10 in the first sub-slurry flow channel a under the action of the gravity of the fluid and/or the external pressure so as to prevent the slurry from accumulating at the slurry inlet 13 to cause consolidation.

Optionally, in the embodiment of the present application, the slurry inlet 13 is disposed at the middle part of the slurry spreading bin 10 in the left-right direction, so that the first sub-slurry flow channels a are uniformly distributed on two sides of the bottom of the slurry inlet 13, and the pipeline pressures of the first sub-slurry flow channels a on two sides are the same, so that the flow velocity of the slurry is the same, and the slurry distribution is more uniform. In other examples, the pulp inlet 13 may be disposed on the left or right side.

As shown in fig. 3, the first sub-pulp flow channel a is located at the left and right sides below the pulp inlet 13, and is mutually communicated with the pulp inlet 13 to form a T-shaped channel, so that pulp is facilitated to flow from the pulp inlet 13 to the left and right sides of the first sub-pulp flow channel a after entering, and pulp is prevented from being accumulated in the middle of the pulp dividing block 14 to cause pulp discharge disorder.

As shown in fig. 2 and 3, the pulp dividing block 14 is provided with a plurality of pulp dividing holes 141 along the left-right direction, and the pulp dividing holes 141 are used for supplying the pulp to flow out of the first sub-pulp dividing flow channel a along the vertical direction, wherein the pulp dividing holes 141 may be uniformly distributed along the left-right direction, or may be distributed in a more densely distributed manner along the left-right sides, that is, the larger the distance between two adjacent pulp dividing holes 141 is, the smaller the distance between two adjacent pulp dividing holes 141 is, the more the distance between two adjacent pulp dividing holes 141 is, and the two adjacent pulp dividing holes 141 are smaller the distance between two adjacent pulp dividing holes. In addition, the size of the size dividing holes is not limited in this embodiment, and the size of the size dividing holes can be specifically set according to the properties of the slurry.

And downward slurry separating openings C are formed between the left and right ends of the slurry separating block 14 and the inner walls of the left and right sides of the slurry spreading bin 10. A second sub-pulp-dividing flow channel B is formed between the pulp-dividing port C and the first sub-pulp-dividing flow channel A, and is obliquely downwards arranged, and the pulp-dividing port C and the first sub-pulp-dividing flow channel A are mutually communicated.

In the embodiment of the application, the second sub-pulp-dividing flow passage B is formed by enclosing the left and right sides of the pulp dividing block 14 and the inner wall of the pulp paving bin 10, the inlet of the second sub-pulp-dividing flow passage B is communicated with the first sub-pulp-dividing flow passage A which is horizontally arranged, and the outlet is communicated with the downward pulp dividing port C, so that the second sub-pulp-dividing flow passage B is in an inclined downward direction. The inclined downward surfaces may be formed on the left and right sides of the block 14, or the inclined downward surfaces may be formed on the inner walls of the corresponding slurry chambers 10 on the left and right sides of the block 14, or, as shown in the examples of fig. 2 and 3, the inclined downward surfaces may be formed on the left and right sides of the block 14 and the inner walls of the corresponding slurry chambers 10.

The second sub-pulp separation flow channel may be uniformly changed from horizontal to downward inclined at a certain radian, or may be downward inclined according to the shapes of the left and right sides of the pulp separation block 14 and the corresponding shapes of the inner walls of the pulp paving bin 10.

In the process of paving the slurry, when the ground is uneven (the situation that the slurry paving position near the wall is high in probability) and the slurry paving height is consistent is ensured, the slurry of the previous brick is paved, the slurry paving height of the ground concave part of the previous brick is higher, the slurry position corresponding to the next brick is possibly insufficient when the next brick is paved, the slurry is deficient, according to the traditional hopper structure, the slurry deficiency probability of the left side and the right side of the next brick is higher, the phenomenon of empty drum is caused when the bricks are paved, in addition, the phenomenon of the left corner and the right corner deficiency easily occurs in the first slurry pumping process, in the embodiment of the application, the slurry flows transversely along the left side and the right side of the first sub slurry flow channel A under the action of self gravity and external pressure, at the moment, part of the slurry flows downwards from the slurry distributing holes 141 on the slurry distributing block 14, and part of the slurry flows towards the left side and the right side of the slurry distributing block 14, finally, the slurry is flowed from the second sub slurry flow channel B and the left side and the right side of the second sub slurry flow channel C to ensure that the left side and the slurry is not flat in the traditional ceramic tile paving process, and the problem of the tile paving process is solved, and the problem of the tile paving technology is solved simultaneously. Meanwhile, due to the arrangement of the second sub-slurry distribution flow channel B which is inclined downwards, the slurry in the first sub-slurry distribution flow channel A is guaranteed to have enough fluid pressure, so that the slurry can smoothly flow out of the slurry distribution holes 141, and the fluid pressure of the slurry which is inclined downwards can be quickly released through inclined downwards flow guide, so that the slurries at two sides can also quickly and smoothly flow downwards.

In addition, the hopper in the prior art is provided with a pulp separating chamber and a pulp storing chamber which are mutually independent and sequentially communicated from top to bottom, the bottom wall of the pulp separating chamber is provided with a through hole, and the pulp storing chamber is communicated with the pulp separating chamber only through the through hole on the bottom wall of the pulp separating chamber. When hard blocks are mixed in the slurry, the slurry is easy to block in the through holes, so that the slurry is not smooth, and the slurry shortage problem is caused. In the structural design of the slurry spreading bin 10 in the embodiment of the application, the slurry dividing block 14 is provided with a plurality of slurry dividing holes 141, and the slurry dividing openings C are arranged between the left end and the right end of the slurry dividing block 14 and the inner walls of the left side and the right side of the slurry spreading bin 10, so that slurry flows out of the slurry dividing holes 141 and also flows out of the slurry dividing openings C on the two sides of the slurry dividing block 14 downwards, and the slurry is prevented from being accumulated in the first sub slurry dividing flow passage A. Further, the diameter of the separating opening C is larger than that of the separating hole 141, and even if the slurry has hard slurry with a diameter larger than that of the separating hole 141, the hard slurry can be led out from the separating openings C on both sides of the separating block 14, thereby preventing the slurry from being blocked in the separating hole 141 and enabling the slurry to be discharged more smoothly.

From the structural view, hopper design in the correlation technique is for mutual independence branch thick liquid room and storage thick liquid room, and the structure is comparatively complicated, and processing is more difficult, and the inner wall has more dead angles and is inconvenient for wasing. The hopper in the embodiment of the application is an integral slurry spreading bin 10, the structure is simpler, the processing is convenient, and dead angles which are difficult to clean do not exist on the inner wall.

The bottom wall structure of the slurry separating chamber of the hopper in the related art has design defects, so that slurry is easy to flow or flow back, and further the slurry is solidified. According to the structural design of the slurry spreading bin 10, the slurry dividing ports C are arranged between the left end and the right end of the slurry dividing block 14 and the inner walls of the left side and the right side of the slurry spreading bin 10, and the slurry dividing ports C are arranged downwards, so that slurry can flow out of the slurry dividing ports C smoothly, namely, the pressure can be quickly relieved, and solidification caused by no flow or backflow accumulation of the slurry can be prevented. In addition, after the slurry flows out from the slurry separating opening C, the slurry passes through the lower homogenizing chamber 20 and can reach the edges of the two sides of the area to be paved, so that the slurry shortage at the two sides can be prevented, and the problem of empty drum is reduced.

As shown in fig. 2 and 3, in the present embodiment, the slurry dividing block 14 is integrally formed, and the integrally formed slurry dividing block 14 can reduce the number of parts and reduce the difficulty of assembly and disassembly. In other embodiments, the slurry dividing block 14 may be formed by mutually splicing a plurality of sub slurry dividing blocks 14, which is helpful for storage and transportation after disassembly. The sizing block 14 may be made of aluminum profile material or other materials.

In the preferred embodiment, the cross-sectional area of the first sub-pulp flow channel a is V2, the cross-sectional area of the pulp inlet 13 is V1, and the following relationship exists between V2 and V1: 1/2 x v1< v2< v1.

It should be noted that: the cross-sectional area V2 of the first sub-pulp separation flow path a is a cross-sectional area along the height direction that can be seen when the first sub-pulp separation flow path a is sectioned along the height direction of the pulp paving bin 10. The cross-sectional area V1 of the inlet 13 is a cross-sectional area in the horizontal direction that can be seen when the inlet 13 is sectioned in the width direction of the slurry spreading bin 10.

In the flow channel design, if the radius of the flow channel is too large, the pushing pressure towards two sides is not formed, and the slurry cannot flow to two sides of the first sub-slurry-dividing flow channel A; if the radius of the flow channel is too small, the pressure is large, the surface of the slurry spreading bin 10 is stressed, the slurry dividing holes 141 with small apertures are easy to form a water drop effect, the slurry still flows away from the middle, and the slurry is less on two sides, so that the slurry is lack in the two side areas. Therefore, in the flow channel design in the present embodiment, the cross-sectional area V2 of the first sub-pulp flow channel a is greater than half of the cross-sectional area V1 of the pulp inlet 13 and smaller than the cross-sectional area V1 of the pulp inlet 13, so that the pulp has a certain "pipeline" pressure in the process of moving transversely in the first sub-pulp flow channel a, forcing the pulp to flow down from the pulp separation holes 141 on the pulp separation block 14; meanwhile, the slurry can be quickly and uniformly distributed to the left and right ends of the slurry distribution block 14 in a limited height, so that slurry shortage at two sides is prevented; furthermore, the height of the slurry spreading bin 10 can be smaller, the whole volume is smaller, the materials are less, the cost is saved, and the weight can be reduced.

The cross section area of the second sub-pulp separation flow channel B is not limited in the embodiment of the application. Optionally, the cross section area of the second sub-pulp separation flow channel B is V3, and V3 is larger than or equal to V2; and V3 increases gradually in its obliquely downward direction. The cross section V3 of the second sub-pulp flow channel B is a cross section area that can be seen when the second sub-pulp flow channel B is cut off along the radial direction thereof.

The cross section V3 of the second sub-pulp-separating flow channel B is larger than or equal to the cross section V2 of the first sub-pulp-separating flow channel A, namely the diameter of a pipeline of the second sub-pulp-separating flow channel B and the diameter of a pipeline of the first sub-pulp-separating flow channel A can be effectively matched, so that the pulp is filled in a moving space in transverse movement, a certain pressure is generated, and the pulp is quickly pushed to a pulp-separating port; the second sub-slurry separation flow passage B is obliquely downwards arranged so as to achieve the aim of pressure relief and facilitate the slurry to flow down from the slurry separation port C.

In a preferred embodiment, the left and right sides of the slurry dividing block 14 are respectively formed with first inclined portions inclined to both sides and downward, the inner wall of the slurry spreading bin 10 is formed with second inclined portions inclined to both sides and downward corresponding to the first inclined portions, and the first inclined portions and the second inclined portions enclose to form a second sub-slurry dividing flow passage B.

The sectional area of the second sub-pulp flow channel B is V3, and the sectional area V3 of the inlet of the second sub-pulp flow channel B is the same as the sectional area V2 of the first sub-pulp flow channel A; the cross section V3 of the outlet of the second sub-pulp-separating flow passage B is larger than the cross section V2 of the first sub-pulp-separating flow passage A, and V3 is gradually increased along the inclined downward direction of the second sub-pulp-separating flow passage B, so that the movement speed of the pulp positioned in front is gradually increased under the double influence of gravity and expansion of the movement space when the pulp flows out, and a gap is formed between the pulp with different front and back movement speeds due to expansion of the space.

The length of the second sub-pulp flow channel B is the length between the inlet and the outlet of the second sub-pulp flow channel B.

The length of the second sub-slurry-dividing flow channel B is not limited in the embodiment of the application. Optionally, the length of the second sub-pulp separation flow channel B may be set according to the pulp discharge requirement and the pulp discharge efficiency. The second sub-pulp separation flow channel B is set to a certain length, so that the pulp can be discharged in the second sub-pulp separation flow channel B in an accelerating way; and a certain degree of pressure relief channel is formed with the first sub-pulp separation flow channel A, and a certain fluid suction force is formed on the pulp in the first sub-pulp separation flow channel A, so that the flow speed of the pulp in the first sub-pulp separation flow channel A is accelerated, and accumulation or residue is reduced.

Optionally, inclined surfaces are further arranged between the upper surface and the left and right end parts of the pulp dividing block 14, so that second sub-pulp dividing flow passages B which are downward inclined are formed by the pulp dividing block 14 and the inner walls of the left and right sides of the pulp paving bin 10. The pressure release capacity is larger when the inclination angle of the second sub-pulp separation flow channel B is too large, and the flow speed of the pulp is not easy to control; if the inclination angle of the second sub-pulp separation flow channel B is too small, the pressure release capability is small, and the pulp spreading efficiency is affected by the slower flow speed of the pulp, so that the included angle between the upper surface of the pulp separation block 14 and the inclined surface, that is, the inclination angle of the second sub-pulp separation flow channel B can be set according to the pulp discharge requirement.

The upper surface structure of the segment 14 is not limited in the embodiments of the present application. Alternatively, as shown in fig. 4, the bottom of the first sub-slurry separation channel a may be arc-shaped to facilitate the flow of slurry. The upper surface of the slurry dividing block 14 forms an arc-shaped groove structure extending along the left-right direction, and the slurry dividing holes 141 are formed in the bottom of the arc-shaped groove structure, so that the slurry can be better discharged, and the slurry residue is reduced.

Further, under the condition that the pulp separation port C, the second sub-pulp separation flow channel B and the first sub-pulp separation flow channel A are mutually communicated to form a pulp separation flow channel with a siphon effect, and the cross sections among the pulp separation port C, the second sub-pulp separation flow channel B and the first sub-pulp separation flow channel A are mutually ingenious matched, the bottom of the first sub-pulp separation flow channel A is arc-shaped, so that the whole pulp separation flow channel can generate stronger siphon effect, the flowing speed of pulp in each section of pulp separation flow channel is faster, and therefore, the cross section of each section of pulp separation flow channel can be designed to be smaller under the condition that the width of each section of pulp separation flow channel is fixed, and the height of a hopper can be smaller.

As shown in fig. 1 and 2, the hopper 100 of the embodiment of the present application includes a front cover plate 11 and a rear cover plate 12, and the front cover plate 11 and the rear cover plate 12 are mutually covered to form a slurry spreading bin 10.

Alternatively, the slurry inlet 13 may be detachably mounted to the front cover plate 11, or the slurry inlet 13 may be detachably mounted to the rear cover plate 12.

Preferably, the front cover plate 11 and the rear cover plate 12 are detachably covered with each other to form the slurry spreading bin 10. Specifically, the front cover plate 11 and the rear cover plate 12 can be fastened with each other through fasteners or connected through fasteners to realize detachable cover.

The front cover plate 11 and the rear cover plate 12 are detachably covered, so that the hopper 100 can be conveniently detached and carried. For example, when it is necessary to lay tiles on a floor where no elevator is installed, the whole machine is inconvenient to transport, the hopper 100 can be quickly disassembled into a plurality of parts, and the parts can be transported to a target floor and assembled for use; in addition, when a certain part of the hopper 100 is damaged, the hopper can be quickly disassembled to conveniently replace the damaged part, so that the hopper has strong universality. Meanwhile, after construction is finished, the front cover plate 11 and/or the rear cover plate 12 of the hopper 100 can be detached, the slurry spreading bin 10 is completely opened so as to be convenient to clean, compared with the prior art that the slurry spreading bin is cleaned through a small Kong Duifen slurry bin, the detachable cleaning mode of the embodiment is easier to operate, the slurry spreading bin 10 can be quickly cleaned, and no slurry remains in dead corners.

Alternatively, the front cover plate 11 and the rear cover plate 12 of the hopper 100 may be made of aluminum profiles. The aluminum profile is an alloy material taking aluminum as a main component, and aluminum bars are extruded through hot melting to obtain aluminum materials with different cross-sectional shapes. The aluminum profile has lighter weight, and the hopper 100 manufactured by the aluminum profile is beneficial to reducing the overall weight of the slurry spreading terminal 1000 and is convenient to carry. In addition, the surface of the aluminum profile has the characteristics of dirt resistance and easy cleaning after oxidation, so that the adoption of the aluminum profile manufacturing hopper 100 is beneficial to reducing the cleaning difficulty of the slurry paving terminal 1000, saving the cleaning time of the slurry paving terminal 1000 after slurry paving and reducing the cleaning cost.
