Description

Technical Field

[0001] This invention belongs to the technical field of mortar mixing equipment, specifically, it relates to a multi-axis linkage high-efficiency mortar mixing mechanical device. Background Technology

[0002] Inadequate mortar mixing is a common construction problem that can lead to a series of serious quality defects and safety hazards. Mortar consists of cement, lime, sand, water, and additives. When mixing is insufficient, a complete and uniform chemical reaction cannot occur. This results in a significant decrease in strength and durability. Cement-rich and cement-poor zones will appear in the mortar. Rich zones may be brittle and prone to shrinkage cracking, while lean zones have extremely low strength, resembling loose sand and unable to withstand loads. Insufficient cement hydration prevents the formation of a dense network structure. The mortar has high porosity and is interconnected, allowing moisture and harmful ions (such as chloride and sulfate ions) to easily penetrate. This can lead to damp walls, corrosion of internal steel reinforcement, and accelerated freeze-thaw damage. The surface is prone to powdering and sanding, making it unable to withstand wind, rain, and daily wear, reducing its abrasion resistance and weather resistance. Furthermore, insufficient adhesion easily leads to hollow areas, causing the plaster layer to detach from the substrate. Severe hollow areas can cause the plaster layer or even the entire masonry structure to fall off, which is extremely dangerous. Additionally, the overall integrity of the masonry wall is poor, significantly weakening its seismic resistance and load-bearing capacity. The reasons for incomplete mixing include insufficient mixing time, improper mixing equipment, and different order of adding the components. Currently, the most significant factor affecting mixing efficiency is the mixing equipment. While general mixing equipment provides good mixing results for small amounts of mortar, sufficient mixing time is required to achieve thorough mixing for large quantities, thus reducing mixing efficiency. Summary of the Invention

[0003] This invention provides a multi-axis linkage high-efficiency mortar mixing machine to achieve thorough mixing of mortar, improve the efficiency of mortar mixing, and avoid the occurrence of dead zones in the mixing process.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A multi-axis linkage high-efficiency mortar mixing machine includes multiple circumferential shaft mixing mechanisms that are rotatably connected in a vertical direction. At the upper and lower ends of the circumferential shaft mixing mechanisms, an upper feed end cover and a lower discharge end cover are respectively installed at the ends furthest from each other. A liquid inlet mixing mechanism extends vertically from the upper feed end cover to the lower discharge end cover. The axes of the liquid inlet mixing mechanism, the upper feed end cover, the lower discharge end cover, and each circumferential shaft mixing mechanism are coincident. The circumferential shaft mixing mechanism in the odd-numbered position is connected to a driving mechanism, and the circumferential shaft mixing mechanism in the even-numbered position is connected to another driving mechanism.

[0005] Furthermore, the circumferential shaft stirring mechanism includes a vertical cylinder and an annular drive shaft. The annular drive shaft is coaxially disposed inside the vertical cylinder and is connected to the vertical cylinder via multiple adapter components. Both ends of the annular drive shaft are rotatably connected to the cylinder wall of the vertical cylinder. Multiple plate-shaped stirring blades are installed on the annular drive shaft at intervals along its circumference. One end of the annular drive shaft is connected to a corresponding drive mechanism.

[0006] Furthermore, the annular drive shaft includes multiple shaft bodies spaced circumferentially along the vertical cylinder. Adjacent shaft bodies are connected by universal couplings. The shaft bodies at both ends are rotatably connected to the cylinder wall of the vertical cylinder. One end of each connecting component is rotatably connected to the corresponding shaft body, and the other end of the connecting component is fixedly connected to the cylinder wall of the vertical cylinder. Each plate-shaped stirring blade is installed on the corresponding shaft body.

[0007] Furthermore, the annular drive shaft includes a flexible drive shaft extending circumferentially along the vertical cylinder. One end of the adapter is rotatably connected to the corresponding end of the flexible drive shaft, and the other end of the adapter is drive-connected to the cylinder wall of the vertical cylinder.

[0008] Furthermore, the adapter includes a support rod with an adapter ring rotatably connected to one end, and the other end of the support rod extends radially out of the vertical cylinder, and the support rod is threadedly connected to the cylinder wall of the vertical cylinder.

[0009] Furthermore, the drive mechanism includes a drive wheel mounted on one axial end of the annular drive shaft, drive wheels on multiple vertically spaced annular drive shafts are connected by a drive chain or drive belt, multiple vertically spaced vertical cylinders are connected by a mounting base, a drive motor is mounted on the mounting base, and the output shaft of the drive motor is coaxially connected to one end of the annular drive shaft.

[0010] Furthermore, an angle adjustment mechanism is provided between the two drive mechanisms. The angle adjustment mechanism has two output ends, and the two output ends are connected to the two drive mechanisms in a one-to-one correspondence.

[0011] Furthermore, the angle adjustment mechanism includes an arc-shaped sleeve disposed on the outer side of the vertical cylinder. The arc-shaped sleeve extends circumferentially along the vertical cylinder. Two arc-shaped drive rods are symmetrically and movably connected inside the arc-shaped sleeve. Pistons are respectively constructed at the ends of the two arc-shaped drive rods that are close to each other. The end of the arc-shaped drive rod away from the piston extends out of the arc-shaped sleeve and is connected to the corresponding mounting seat. A first drive chamber is formed in the inner cavity of the arc-shaped sleeve and at the position between the two pistons. A second drive chamber is formed in the inner cavity of the arc-shaped sleeve and between the corresponding ends of the pistons and the arc-shaped sleeve. The first drive chamber is connected to the first connecting pipe, and both second drive chambers are connected to the second connecting pipe.

[0012] Furthermore, the liquid-feeding stirring mechanism includes a central rod extending vertically to the lower discharge end cover. The upper part of the central rod is rotatably connected to the upper feed end cover. A stirring assembly is provided on the central rod and between adjacent circumferential shaft stirring mechanisms. A bottom scraper blade is installed on the lower part of the central rod.

[0013] Furthermore, the stirring assembly includes a plurality of assembly tubes evenly arranged circumferentially along the central rod, and a guiding channel extending along its axis is provided inside the central rod. The guiding channel is connected to each assembly tube, and a plurality of liquid outlet holes are provided on the assembly tubes. Inclined disturbance blades are constructed on the assembly tubes.

[0014] The present invention, by employing the aforementioned structure, achieves a technological advancement compared to existing technologies in that: the multiple circumferential shaft stirring mechanisms of the present invention are divided into two groups, namely an odd-numbered group and an even-numbered group. That is, counting downwards vertically, the odd-numbered circumferential shaft stirring mechanisms are classified as an odd-numbered group, and the even-numbered group as an even-numbered group. One drive mechanism is connected to the odd-numbered group, and the other drive mechanism is connected to the even-numbered group. The present invention can control the two drive mechanisms to move synchronously in the same direction, allowing adjacent circumferential shaft stirring mechanisms to simultaneously stir the mortar upwards or downwards, thereby causing the mortar in the entire device to tumble from bottom to top or from top to bottom, avoiding uneven mixing. The present invention can also control the two drive mechanisms to move synchronously in opposite directions, allowing adjacent circumferential shaft stirring mechanisms to simultaneously stir the mortar in opposite directions vertically, thereby dividing the entire device into multiple convection zones (each pair of adjacent circumferential shaft stirring mechanisms and the area between them constitutes a convection zone). The mortar convects within these convection zones through the two circumferential shaft stirring mechanisms, thereby improving the thoroughness of mixing. Simultaneously, the liquid-injection mixing mechanism is driven to rotate, and during rotation, a portion of pressurized water is injected into the device through the liquid-injection mixing mechanism. This allows the liquid-injection mixing mechanism to agitate the mortar, and under the action of high-pressure water, the various components of the mortar are fully agitated and mixed. In other words, before mortar mixing, dry materials are first added to the entire device for preliminary mixing, and then water is gradually injected through the liquid-injection mixing mechanism. When the amount of water added reaches a predetermined value, the mortar is ready. In summary, this invention uses multiple circumferential shaft mixing mechanisms to agitate and disturb the mortar in different ways, combined with the mixing of the liquid-injection mixing mechanism, enabling the mortar to mix quickly and thoroughly, improving the mixing efficiency and avoiding the formation of mixing dead zones.

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0019] This invention discloses a multi-axis linkage high-efficiency mortar mixing mechanical device, such as... Figure 1-11As shown, the system includes a liquid-feeding stirring mechanism 600, an upper feed end cover 200, a lower discharge end cover 300, two drive mechanisms 400, and multiple circumferential shaft stirring mechanisms 100. These circumferential shaft stirring mechanisms 100 are rotatably connected together in a vertical direction. The upper feed end cover 200 is installed at the upper end of the uppermost circumferential shaft stirring mechanism 100, and the lower discharge end cover 300 is installed at the lower end of the lowermost circumferential shaft stirring mechanism 100. The liquid-feeding stirring mechanism 600 extends vertically from the upper feed end cover 200 to the lower discharge end cover 300, and the axes of the liquid-feeding stirring mechanism 600, the upper feed end cover 200, the lower discharge end cover 300, and each circumferential shaft stirring mechanism 100 coincide. The circumferential shaft stirring mechanism 100 located in odd-numbered positions is connected to one of the drive mechanisms 400, and the circumferential shaft stirring mechanism 100 located in even-numbered positions is connected to the other drive mechanism 400. The working principle and advantages of this invention are as follows: the multiple circumferential shaft stirring mechanisms 100 are divided into two groups, an odd-numbered group and an even-numbered group. That is, counting downwards vertically, the odd-numbered circumferential shaft stirring mechanisms 100 are divided into an odd-numbered group, and the even-numbered circumferential shaft stirring mechanisms 100 are divided into an even-numbered group. One drive mechanism 400 is connected to the odd-numbered group, and the other drive mechanism 400 is connected to the even-numbered group. This invention can control the two drive mechanisms 400 to move synchronously in the same direction, so that adjacent circumferential shaft stirring mechanisms 100 synchronously stir the mortar inside, thereby causing the mortar in the entire device to tumble from bottom to top or from top to bottom, avoiding uneven mixing. This invention can also control the two drive mechanisms 400 to operate synchronously in opposite directions, so that adjacent circumferential shaft stirring mechanisms 100 synchronously stir the mortar inside in a vertically opposite direction, thereby dividing the entire device into multiple convection zones (each pair of adjacent circumferential shaft stirring mechanisms 100 and the area between them constitutes a convection zone). The mortar convects within the convection zone through the two circumferential shaft stirring mechanisms 100, thereby improving the thoroughness of mixing. Simultaneously, the liquid-injection stirring mechanism 600 is driven to rotate, and during rotation, a portion of pressurized clean water is injected into the device through the liquid-injection stirring mechanism 600. In this way, the liquid-injection stirring mechanism 600 stirs the mortar, and under the action of high-pressure clean water, the components of the mortar are fully agitated and mixed. That is, before mortar mixing, dry materials are first added to the entire device and initially mixed, then clean water is gradually injected through the liquid-injection stirring mechanism 600. When the amount of clean water added reaches a predetermined value, the mortar is prepared. In summary, the present invention uses multiple circumferential shaft mixing mechanisms 100 to mix and agitate the mortar in different ways, and cooperates with the mixing of the liquid inlet mixing mechanism 600, so that the mortar can be mixed quickly and thoroughly, improving the mixing efficiency of the mortar and avoiding the occurrence of mixing dead zones.

[0020] As a preferred embodiment of the present invention, such as Figure 3-5 As shown, the circumferential shaft stirring mechanism 100 includes a vertical cylinder 101, an annular drive shaft, multiple plate-shaped stirring blades 105, and multiple connecting components. A first connecting edge 102 is formed at the lower end of the vertical cylinder 101, and a second connecting edge 103 is formed at the upper end of the vertical cylinder 101. Corresponding first connecting edges 102 and second connecting edges 103 in adjacent vertical cylinders 101 are rotatably connected together. In this embodiment, the annular drive shaft is coaxially disposed within the vertical cylinder 101, and both ends of the annular drive shaft are rotatably connected to the cylinder wall of the vertical cylinder 101. The annular drive shaft is connected to the vertical cylinder 101 through the aforementioned multiple connecting components, which are evenly arranged circumferentially around the vertical cylinder 101. These connecting components serve to connect and support the annular drive shaft. The aforementioned plurality of plate-shaped stirring blades 105 are installed at circumferential intervals on the annular drive shaft, and one end of the annular drive shaft is connected to the corresponding drive mechanism 400. The working principle and advantages of this embodiment are as follows: This embodiment controls the drive mechanism 400 to drive the annular drive shaft, which in turn causes each plate-shaped stirring blade 105 to rotate, causing the mortar inside the vertical cylinder 101 and located within the annular drive shaft to churn and replace the mortar outside the annular drive shaft; that is, the rotation direction of the plate-shaped stirring blades 105 is radial to the vertical cylinder 101. When each plate-shaped stirring blade 105 rotates clockwise, it disturbs and drives the mortar outside the annular drive shaft to the inside of the annular drive shaft, giving the mortar a downward tendency. As the annular drive shafts in adjacent circumferential shaft stirring mechanisms 100 rotate in the same direction, the mortar is driven to move downwards step by step, thereby achieving the purpose of fully replacing the mortar from top to bottom. When each plate-shaped mixing blade 105 rotates counterclockwise, it agitates and drives the mortar inside the annular drive shaft to the outside of the shaft, causing the mortar to tend to move upwards. This ensures that as the annular drive shafts in adjacent circumferential shaft mixing mechanisms 100 rotate in the same direction, the mortar is driven upwards step by step, achieving thorough displacement of the mortar from bottom to top. When adjacent annular drive shafts rotate in opposite directions, all the upper plate-shaped mixing blades 105 rotate clockwise, and all the lower plate-shaped mixing blades 105 rotate counterclockwise, causing convection currents in the mortar and thus improving the mixing efficiency of the mortar in that area.

[0021] As a preferred embodiment of the present invention, such as Figure 5As shown, the annular drive shaft includes multiple shaft bodies 109 and multiple universal couplings 110. These shaft bodies 109 are spaced apart circumferentially along the vertical cylinder 101. Adjacent shaft bodies 109 are connected by a universal coupling 110. The shaft bodies 109 at both ends are rotatably connected to the cylinder wall of the vertical cylinder 101. One end of each transition component is rotatably connected to the corresponding shaft body 109, and the other end of the transition component is fixedly connected to the cylinder wall of the vertical cylinder 101. The transition component is generally a rod-shaped structure, with a sleeve-shaped structure at one end. This sleeve-shaped structure is fitted over the shaft body 109 and rotatably connected to it. Each plate-shaped mixing blade 105 is mounted on a corresponding shaft body 109. The shaft body 109 at the end is driven to rotate, and then all the shaft bodies 109 rotate by the transmission of the universal coupling 110. During the rotation of the shaft body 109, the plate-shaped mixing blades 105 on it are driven to mix the mortar.

[0022] As a preferred embodiment of the present invention, such as Figure 3 , 4 As shown, the annular drive shaft includes a flexible drive shaft 104, which extends circumferentially along the vertical cylinder 101. One end of the adapter component is rotatably connected to the corresponding end of the flexible drive shaft 104, and the other end of the adapter component is rotatably connected to the cylinder wall of the vertical cylinder 101. Specifically, in this embodiment, the adapter component includes a support rod 106, with an adapter ring 107 rotatably connected to one end of the support rod 106. The adapter ring 107 is fitted around the flexible drive shaft 104 and rotatably connected to it. The other end of the support rod 106 extends radially out of the vertical cylinder 101. An operating head 108 is constructed at the end of the support rod 106 away from the adapter ring 107, and the support rod 106 is threadedly connected to the cylinder wall of the vertical cylinder 101. In this embodiment, a flexible drive shaft 104 is used. Driven by the driven mechanism 400, the flexible drive shaft 104 rotates and drives the plate-shaped stirring blades 105 on it to stir the mortar. Because the support rod 106 is threadedly connected to the vertical cylinder 101, the length of the support rod 106 extending into the vertical cylinder 101 is adjusted to keep the flexible drive shaft 104 in a tensioned state, allowing it to effectively drive the plate-shaped stirring blades 105. Furthermore, when maintenance is required on the flexible drive shaft 104 and / or the plate-shaped stirring blades 105, the flexible drive shaft 104 can be removed from the vertical cylinder 101 by separating the support rod 106, improving the ease of disassembly and assembly.

[0023] As a preferred embodiment of the present invention, such as Figure 8As shown, the drive mechanism 400 includes a mounting base 403, a drive motor 404, and multiple transmission wheels 401. Each transmission wheel 401 is coaxially mounted to one axial end of a corresponding annular transmission shaft. The transmission wheels 401 in the odd-numbered or even-numbered circumferential shaft stirring mechanisms 100 are connected via a transmission chain 402 or a transmission belt. The transmission wheels 401 are generally sprockets or pulleys. All vertical cylinders 101 in the odd-numbered array are connected to the mounting base 403, and all vertical cylinders 101 in the even-numbered array are connected to another mounting base 403. In this embodiment, the drive motor 404 is mounted on the mounting base 403. The output shaft of the drive motor 404 is coaxially connected to the end of one of the annular transmission shafts. By controlling the operation of the drive motor 404, all annular transmission shafts in the odd-numbered array rotate synchronously and in the same direction under the transmission of the sprocket or pulley, and all annular transmission shafts in the even-numbered array rotate synchronously and in the same direction. Furthermore, controlling the forward or reverse movement of the two drive motors 404 allows the rotation direction of the annular drive shaft in the odd-numbered group to be the same as or opposite to that in the even-numbered group, thereby causing the mortar in the entire device to tumble from bottom to top or from top to bottom, avoiding unevenness between the top and bottom; or the mortar to convect in multiple convection zones, thereby improving the thoroughness of mixing.

[0024] As a preferred embodiment of the present invention, such as Figure 1 , 8As shown in Figures 9 and 10, an angle adjustment mechanism 500 is provided between the two drive mechanisms 400. This angle adjustment mechanism 500 is located on the outside of the entire device and mounted on a nearby fixed frame. The angle adjustment mechanism 500 has two output ends, which are connected one-to-one with each of the two drive mechanisms 400. In this embodiment, by controlling the movement of the angle adjustment mechanism 500, the two output ends of the angle adjustment mechanism 500 are moved closer to or further away from each other. The movement trajectory of each output end is a certain angle along the circumference of the vertical cylinder 101. Thus, the angle adjustment mechanism 500 drives all the vertical cylinders 101 in the odd-numbered group to rotate. Simultaneously, the angle adjustment mechanism 500 drives all the vertical cylinders 101 in the even-numbered group to rotate, with the rotation direction of the vertical cylinders 101 in the odd-numbered group opposite to that in the even-numbered group. The two drive mechanisms 400 also move synchronously with the corresponding odd-numbered or even-numbered groups. Because the vertical cylinder 101 reciprocates within a certain range along its axis, it drives the annular drive shaft to move synchronously. The plate-shaped stirring blades 105 on the annular drive shaft also rotate along the axis of the vertical cylinder 101, thereby ensuring that the plate-shaped stirring blades 105 can agitate the mortar inside the vertical cylinder 101 in all directions. Moreover, in conjunction with the radial rotation of the plate-shaped stirring blades 105 along the vertical cylinder 101, the mortar is agitated inward and outward, up and down, and diagonally, achieving multi-directional agitation of the mortar and improving the mixing efficiency and effect. In this embodiment, the specific structure of the angle adjustment mechanism 500 is as follows: the angle adjustment mechanism 500 includes an arc-shaped sleeve 501 and two arc-shaped drive rods 502. The arc-shaped sleeve 501 is disposed on the outside of the vertical cylinder 101 and extends circumferentially along the vertical cylinder 101. Two arc-shaped drive rods 502 are symmetrically arranged, with their ends close to each other extending into the arc-shaped sleeve 501. Pistons 503 are respectively constructed at the ends of the two arc-shaped drive rods 502 that are close to each other. The end of the arc-shaped drive rod 502 away from the piston 503 extends out of the arc-shaped sleeve 501 and is provided with a second connecting ear 504. A first connecting ear 405 is constructed on the side of the corresponding mounting base 403 near the arc-shaped drive rod 502. The first connecting ear 405 and the second connecting ear 504 are detachably connected together.In this embodiment, a first driving cavity 505 is formed in the inner cavity of the arc-shaped sleeve 501 and between the two pistons 503. A second driving cavity 506 is formed in the inner cavity of the arc-shaped sleeve 501 and between the corresponding ends of the pistons 503 and the arc-shaped sleeve 501. A first connecting pipe 507 is fixedly connected at the middle position of the arc-shaped sleeve 501, and the first connecting pipe 507 communicates with the first driving cavity 505. A transfer pipe 508 is fixedly connected at both ends of the arc-shaped sleeve 501. Each transfer pipe 508 communicates with the corresponding second driving cavity 506, and these two transfer pipes 508 communicate with the guide pipe 509. A second connecting pipe 510 is connected to the guide pipe 509. Thus, the second connecting pipe 510 communicates with the two second driving cavities 506 through the guide pipe 509 and the two transfer pipes 508. In this embodiment, the pressure medium is introduced into the first connecting pipe 507, allowing it to enter the first driving chamber 505. The pressure medium in the two second driving chambers 506 is discharged through the second connecting pipe 510, causing the two arc-shaped driving rods 502 to move away from each other. These two arc-shaped driving rods 502 are driven by two driving mechanisms 400 to rotate the odd and even groups in opposite directions. When the pressure medium is discharged from the first connecting pipe 507 and enters the two second driving chambers 506 through the second connecting pipe 510, the two arc-shaped driving rods 502 move closer to each other, and the odd and even groups perform the opposite action. In this way, the angle adjustment mechanism 500 operates alternately according to the above two actions, making the mortar more fully and thoroughly mixed, and significantly reducing the mixing time. In this embodiment, two fixing ears 511 are constructed on the arc-shaped sleeve 501, and these two fixing ears 511 are detachably connected to the fixing frame.

[0025] As a preferred embodiment of the present invention, such as Figure 1 , 11As shown, the liquid-feeding mixing mechanism 600 includes a central rod 601, a bottom scraper blade 606, and multiple mixing components. The lower end of the central rod 601 extends vertically to the lower discharge end cover 300. The upper part of the central rod 601 is rotatably connected to the upper feed end cover 200, and a connecting wheel is coaxially mounted on the upper part of the central rod 601, which is driven to rotate the central rod 601. The multiple mixing components are spaced apart on the central rod 601 along its axis, with each mixing component located between two adjacent circumferential shaft mixing mechanisms 100. The bottom scraper blade 606 is installed at the lower part of the central rod 601. This bottom scraper blade 606 is used to mix the mortar at the lower discharge end cover 300 and to scrape the inner circumferential wall of the lower discharge end cover 300. The mixing assembly of this embodiment is used to compensate for the dead angle of mortar disturbance caused by two adjacent circumferential shaft mixing mechanisms 100. When all the circumferential shaft mixing mechanisms 100 drive the mortar vertically in the same direction, the rotation direction of the central rod 601 is controlled so that the mortar is driven vertically step by step, which promotes the vertical movement of the mortar. When the adjacent circumferential shaft mixing mechanisms 100 synchronously stir the mortar in opposite directions vertically and form a convection zone, the mixing assembly is located in the convection zone and improves the mixing effect of the mortar in the convection zone. The mixing assembly of this embodiment includes multiple assembly tubes 602, which are uniformly arranged around the circumference of the central rod 601. A guide channel 603 extending along its axis is opened in the central rod 601. The guide channel 603 is interconnected with each assembly tube 602. Multiple liquid outlet holes 604 are opened on the assembly tubes 602, and inclined disturbance blades 605 are constructed on the assembly tubes 602. When the central rod 601 rotates clockwise, the agitator blade 605 rotates accordingly and guides the water upward; when the central rod 601 rotates counterclockwise, the agitator blade 605 rotates accordingly and guides the water downward. The upper end of the central rod 601 is rotatably connected to the water inlet pipe. The pressurized clean water enters each assembly pipe 602 through the guide channel 603, and then is ejected from the liquid outlet 604.

[0026] As a preferred embodiment of the present invention, such as Figure 6 As shown, the upper feed end cap 200 includes an upper cover body 201, on which a feed inlet 204 is constructed, through which dry materials are fed. A first vertical edge 202 extending downward is constructed at the outer edge of the upper cover body 201, and a third connecting edge 203 is constructed at the lower end of the first vertical edge 202, which is rotatably connected to a corresponding second connecting edge 103.

[0027] As a preferred embodiment of the present invention, such as Figure 7As shown, the lower discharge end cap 300 includes a lower cover body 301, the radial length of which decreases downwards in the vertical direction. A second vertical edge 302 is constructed at the upper outer edge of the lower cover body 301, and a fourth connecting edge 303 is constructed at the upper end of the second vertical edge 302. The fourth connecting edge 303 is rotatably connected to the corresponding first connecting edge 102. A discharge pipe 304 is constructed at the lower end of the lower cover body 301, and a control valve 305 is installed on the discharge pipe 304.
