Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a mortar pipeline transportation system for building engineering. Background Technology

[0002] Mortar is a bonding material used in bricklaying. It is made by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion. Mortar conveyors play a very important role in construction projects. They can quickly and accurately transport mortar and other building materials to the places where they are needed.

[0003] Currently, most mortar conveyors use internal augers to transport mortar. However, residual mortar inside the mortar conveyor tends to deposit on the surface of the auger and the inner wall of the conveying pipe. After drying, the residual mortar not only affects the volume inside the conveying pipe, but also affects the quality of subsequent mortar. Furthermore, the reduced volume inside the conveying pipe due to the dried mortar will also affect the efficiency of subsequent mortar conveying operations.

[0004] Chinese invention patent application CN202410839611.9 discloses a mortar conveying system that can reduce blockages inside the discharge pipe and solve the problem that some mortar conveyors are inconvenient for workers to clean after use, which can affect subsequent conveying efficiency. However, in actual operation, the conveying pipe and auger need to be disassembled and cleaned, and then reinstalled. The operation is cumbersome, increasing the workload and labor intensity of workers and reducing the cleaning efficiency of the conveying pipe. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to propose a mortar pipeline transportation system for building engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mortar pipeline conveying system for construction engineering includes a frame and a feed hopper mounted on the frame. A conveying pipe is also mounted on the frame, and an auger conveyor is rotatably connected inside the conveying pipe. The conveying pipe has an inlet and an outlet. The inlet of the conveying pipe is connected to the lower opening of the feed hopper, and the outlet of the conveying pipe is connected to a discharge pipe. A servo motor for driving the auger conveyor to rotate is mounted at one end of the conveying pipe. A first cleaning component for cleaning residual mortar on the inner wall of the conveying pipe and a second cleaning component for cleaning the outer wall of the auger conveyor are mounted on the conveying pipe.

[0008] Preferably, the conveying pipe includes a first connecting pipe, a second connecting pipe, and a main body rotatably disposed between the first connecting pipe and the second connecting pipe. The inlet of the conveying pipe is located at the top of the first connecting pipe, and the outlet of the conveying pipe is located at the bottom of the second connecting pipe.

[0009] Preferably, the first cleaning assembly includes an ear plate fixed to the second connecting pipe, a screw rotatably connected to the ear plate, a collar disposed on the screw, a rubber striking element connected to the collar, and a drive motor fixed to the ear plate for driving the screw to rotate.

[0010] Preferably, the first cleaning assembly further includes a drive gear fixed on the screw and a driven gear disposed on the main body, wherein the drive gear and the driven gear are meshed together.

[0011] Preferably, a sleeve is threaded onto the screw, the collar is rotatably connected to the sleeve, a guide strip is fixed on the collar, and a guide groove for sliding of the guide strip is provided on the screw.

[0012] Preferably, the second cleaning component includes a movable groove formed in the main pipe and a water cavity formed in the second connecting pipe. A rotating column is rotatably connected in the movable groove. A plurality of spherical nozzles are connected to the rotating column by a pin. A torsion spring for driving the spherical nozzles to reset and rotate is sleeved on the pin. A connecting pipe is connected to the end of the rotating column. Each spherical nozzle is connected to the connecting pipe by a hose. A rotating plate connected to the connecting pipe is rotatably connected in the water cavity. A pump body connected to the connecting pipe is provided on the rotating plate.

[0013] Preferably, a movable gear is fixed on the connecting pipe, and a gear ring that meshes with the movable gear is fixed inside the second connecting pipe.

[0014] Preferably, a sliding rod for connecting a plurality of spherical nozzles is slidably connected inside the main pipe. The sliding rod is connected to the end of the spherical nozzles via a rotating shaft. The end of the sliding rod is set as an arc surface. An annular groove is opened inside the second connecting pipe. A plurality of protrusions that move against the arc surface of the sliding rod are fixed on the inner wall of the annular groove.

[0015] Preferably, the outer wall of the first connecting pipe is fixedly provided with an annular shell, the main pipe body is provided with a communication port for connecting the movable groove and the inner cavity of the annular shell, and the bottom of the annular shell is fixedly provided with a waste outlet.

[0016] Preferably, the conveying pipe is inclined on the frame, and a support leg is fixed at the end of the conveying pipe away from the frame.

[0017] Compared with the prior art, the present invention provides a mortar pipeline transportation system for construction engineering, which has the following beneficial effects:

[0018] 1. The mortar pipeline conveying system for this construction project automatically cleans the residual mortar on the inner wall of the conveying pipe by controlling the first cleaning component, and the second cleaning component cleans the residual mortar on the auger conveyor plate. There is no need to disassemble the machine to clean the conveying pipe and the auger conveyor plate. The operation is simple and convenient, reducing the workload and labor intensity of the workers and improving the cleaning efficiency of the conveying pipe.

[0019] 2. The mortar pipeline conveying system for this construction project allows the rubber striking element to be displaced axially along the main pipe, while the main pipe rotates during this period. This enables the rubber striking element to strike different positions on the main pipe, avoiding damage to the same position from constant striking, while ensuring that the mortar on the inner wall of the main pipe is easily loosened and cleaned due to the shaking.

[0020] 3. The mortar pipeline conveying system used in this construction project intermittently abuts the end of the slide bar against the protrusion, causing the spherical nozzle to swing when the slide bar moves. This increases the spray range and spray angle of the spherical nozzle on the inner wall of the main pipe and the auger conveyor plate, thereby improving the removal effect of residual mortar on the inner wall of the conveying pipe and the auger conveyor plate.

[0021] 4. The mortar pipeline conveying system used in this construction project rotates relative to the main pipe. Some of the mortar adhering to the outside of the rotating column is scraped off, but some mortar still accumulates at the connection between the spherical nozzle and the rotating column. When the spherical nozzle sprays water towards the inner wall of the top of the movable trough, the water sprayed by the spherical nozzle flows between the inner wall of the movable trough and the rotating column. The water carries the residual mortar down the rotating column and enters the annular shell through the connecting port, and finally exits from the waste port at the bottom of the annular shell. When the conveying pipe is conveying mortar, the side of the rotating column without the spherical nozzle faces the inner wall of the main pipe to avoid excessive mortar accumulation and nozzle blockage at the connection between the spherical nozzle and the rotating column. Only during cleaning operations is the rotating column driven to rotate the spherical nozzle, so that the spherical nozzle faces the inner wall of the main pipe, thereby washing away the residual mortar on the inner wall of the main pipe and the auger conveyor plates.

[0033] Example: Refer to Figure 1 and Figure 2 A mortar pipeline conveying system for construction engineering includes a frame 1 and a feed hopper 2 mounted on the frame 1. A conveying pipe 3 is also mounted on the frame 1. An auger conveyor plate 4 is rotatably connected inside the conveying pipe 3. The conveying pipe 3 is provided with an inlet and an outlet. The inlet of the conveying pipe 3 is connected to the lower opening of the feed hopper 2. The outlet of the conveying pipe 3 is connected to a discharge pipe 5. A servo motor 6 for driving the auger conveyor plate 4 to rotate is provided at one end of the conveying pipe 3. A first cleaning component for cleaning residual mortar on the inner wall of the conveying pipe 3 and a second cleaning component for cleaning the outer wall of the auger conveyor plate 4 are provided on the conveying pipe 3.

[0034] Furthermore, the conveying pipe 3 is inclinedly mounted on the frame 1, and a support leg 16 is fixed at the end of the conveying pipe 3 away from the frame 1.

[0035] Specifically, mortar is poured into the feed hopper 2 and enters the conveying pipe 3 through the feed inlet. The servo motor 6 is controlled to run, causing the servo motor 6 to drive the auger conveyor plate 4 to rotate inside the conveying pipe 3. The auger conveyor plate 4 conveys the mortar in the conveying pipe 3 obliquely upward and discharges it to the designated position through the discharge pipe 5. After the mortar conveying operation is completed, the auger conveyor plate 4 is kept in a rotating state. The first cleaning component is controlled to automatically clean the residual mortar on the inner wall of the conveying pipe 3, and the second cleaning component cleans the residual mortar on the auger conveyor plate 4. There is no need to disassemble the machine to clean the conveying pipe 3 and the auger conveyor plate 4. The operation is simple and convenient, reducing the workload and labor intensity of the staff and improving the cleaning efficiency of the conveying pipe 3.

[0036] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the conveying pipe 3 includes a first connecting pipe 301, a second connecting pipe 302, and a main pipe body 303 rotatably disposed between the first connecting pipe 301 and the second connecting pipe 302. The inlet of the conveying pipe 3 is opened at the top of the first connecting pipe 301, and the outlet of the conveying pipe 3 is opened at the bottom of the second connecting pipe 302.

[0037] Furthermore, the first cleaning assembly includes an ear plate 7 fixed to the second pipe 302, a screw 702 rotatably connected to the ear plate 7, a collar 703 disposed on the screw 702, a rubber striking element 704 connected to the collar 703, and a drive motor 705 fixed to the ear plate 7 for driving the screw 702 to rotate.

[0038] Furthermore, the first cleaning assembly also includes a drive gear 706 fixed on the screw 702 and a driven gear 701 disposed on the main body 303, with the drive gear 706 and the driven gear 701 meshing together.

[0039] Furthermore, a sleeve 8 is threadedly connected to the screw 702, and a collar 703 is rotatably connected to the sleeve 8. A guide bar 7031 is fixed on the collar 703, and a guide groove 7021 for sliding the guide bar 7031 is provided on the screw 702.

[0040] Specifically, when the first cleaning component is working, the drive motor 705 is controlled to run. The output shaft of the drive motor 705 drives the screw 702 to rotate. When the screw 702 rotates, it drives the drive gear 706 to rotate. The drive gear 706 meshes with the driven gear 701, causing the driven gear 701 to drive the main body 303 to rotate relative to the first connector 301 and the second connector 302. The sleeve 8 also moves axially along the screw 702 when the screw 702 rotates. It should be noted that a guide rod should be provided in the axial direction of the screw 702 to limit the movement direction of the sleeve 8. This is common knowledge in the field and will not be elaborated here. When the sleeve 8 moves axially along the screw 702, it drives the collar 703 to move. 3. During the movement of the sleeve 8, the guide bar 7031 and guide groove 7021 cooperate with the screw 702 to rotate synchronously, so that the collar 703 drives the rubber striking part 704 to strike the outer wall of the main body 303, causing the main body 303 to shake, which makes the mortar adhering to the inner wall of the main body 303 easier to fall off. The rotating auger conveyor plate 4 conveys and discharges the mortar. Since the rubber striking part 704 is displaced along the axial direction of the main body 303 and the main body 303 rotates during this period, the rubber striking part 704 can strike different positions of the main body 303. This avoids the main body 303 being damaged by constant striking at the same position, while ensuring that the mortar on the inner wall of the main body 303 is easily loosened and cleaned due to shaking.

[0041] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the second cleaning component includes a movable groove 9 opened in the main pipe 303 and a water cavity 10 opened in the second connecting pipe 302. A rotating column 901 is rotatably connected in the movable groove 9. A plurality of spherical nozzles 902 are connected to the rotating column 901 by a pin. A torsion spring for driving the spherical nozzles 902 to reset and rotate is sleeved on the pin. A connecting pipe 903 is connected to the end of the rotating column 901. Each spherical nozzle 902 is connected to the connecting pipe 903 by a hose. A rotating plate 1001 connected to the connecting pipe 903 is rotatably connected in the water cavity 10. A pump body connected to the connecting pipe 903 is provided on the rotating plate 1001.

[0042] Furthermore, a movable gear 9031 is fixedly mounted on the connecting pipe 903, and a gear ring 11 that meshes with the movable gear 9031 is fixedly mounted inside the second connecting pipe 302.

[0043] Furthermore, a slide rod 12 for connecting several spherical nozzles 902 is slidably connected inside the main pipe 303. The slide rod 12 is connected to the end of the spherical nozzle 902 through a rotating shaft. The end of the slide rod 12 is set as an arc surface. An annular groove 13 is opened inside the second pipe 302. Several protrusions 131 that move against the arc surface of the slide rod 12 are fixed on the inner wall of the annular groove 13.

[0044] Furthermore, the outer wall of the first connecting pipe 301 is fixedly provided with an annular shell 14, the main pipe body 303 is provided with a communication port 15 for connecting the movable groove 9 and the inner cavity of the annular shell 14, and the bottom of the annular shell 14 is fixedly provided with a waste port 141.

[0045] Specifically, when the main pipe 303 rotates relative to the first connecting pipe 301 and the second connecting pipe 302, the main pipe 303 drives the rotating column 901 to rotate. The movable gear 9031 on the outer side of the connecting pipe 903 on the rotating column 901 meshes with the gear ring 11 on the first connecting pipe 301. The rotating column 901 rotates relative to the main pipe 303, so that the spherical nozzle 902 on the rotating column 901 can face the inside of the main pipe 303. The water sprayed by the spherical nozzle 902 impacts the auger conveyor plate 4 and the inner wall of the main pipe 303. As the auger conveyor plate 4 pushes the mortar remaining on the inner wall of the main pipe 303, the mortar adheres to the outside of the rotating column 901. As the rotating column 901 rotates relative to the main pipe 303, some of the mortar adhering to the outside of the rotating column 901 is scraped off. However, some mortar still accumulates at the connection between the spherical nozzle 902 and the rotating column 901. When the spherical nozzle 902 sprays water towards the top inner wall of the movable trough 9, the water sprayed by the spherical nozzle 902 flows between the inner wall of the movable trough 9 and the rotating column 901, carrying with it the residual mortar. The mortar slides down the rotating column 901 and enters the annular outer shell 14 through the connecting port 15, and is finally discharged from the waste port 141 at the bottom of the annular outer shell 14. As the rotating column 901 rotates relative to the first connecting pipe 301 with the main pipe 303, the end of the sliding rod 12 intermittently abuts against the protrusion 131, causing the sliding rod 12 to move and drive the spherical nozzle 902 to swing, increasing the spray range and spray angle of the spherical nozzle 902 on the inner wall of the main pipe 303 and the auger conveyor plate 4, thus improving the spray coverage on the inner wall of the conveying pipe 3 and the auger conveyor plate. 4. Residual mortar removal effect: When mortar is conveyed in the conveying pipe 3, the side of the rotating column 901 without the spherical nozzle 902 faces the inner wall of the main body 303 to avoid excessive mortar accumulation and blockage of the spherical nozzle 902 at the connection between the spherical nozzle 902 and the rotating column 901. Only when cleaning is performed does the rotating column 901 drive the spherical nozzle 902 to rotate, so that the spherical nozzle 902 faces the inner wall of the main body 303, thereby washing away the residual mortar on the inner wall of the main body 303 and the auger conveyor plate 4.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
