Description

Technical Field

[0001] This utility model relates to the field of mortar mixing, and in particular to an integrated machine for mixing and conveying cementitious mortar. Background Technology

[0002] The cementitious mortar mixing and conveying integrated machine mainly consists of multiple storage tanks, a mixing device, and a finished product conveying device. The multiple storage tanks are connected to the corresponding feed inlets at the top of the mixing device. Different mortar raw materials in the storage tanks enter the mixing device through the feed inlets. The mixing device uniformly mixes the raw materials to form the finished cementitious mortar. After mixing, the finished mortar is conveyed to the designated location by the finished product conveying device. However, existing integrated cementitious mortar mixing and conveying machines have many inconveniences: during long-term mixing operations, mortar residue is easily adhered to the inner wall of the mixing device, and the mixing blades will also experience a decrease in mixing efficiency due to wear and material adhesion. Therefore, it is necessary to clean and replace the inside of the mixing device and the mixing blades regularly. However, since the mixing device is directly fixed to the storage tank and the connection structure is complex, the overall disassembly process of the mixing device is cumbersome, which in turn makes the maintenance and disassembly of the mixing blades more difficult.

[0003] For example, patent CN218905841U discloses a mortar mixing device, in which an auxiliary rotating shaft extends into the mixing chamber and is fixedly connected to an auxiliary rotating strip; auxiliary scrapers are fixedly connected to both ends of the auxiliary rotating strip, and the auxiliary scrapers are in contact with the side wall of the mixing chamber; this can solve the problems of insufficient mixing at the bottom of the mortar mixing device and insufficient mixing of the material adhering to the side wall, resulting in material waste, but it still has some drawbacks: Its mixing chamber is a single unit, meaning that it is not easy to replace the mixing blades after they are damaged. Furthermore, it only has a single output pipe, which can only transport the finished mortar to a single pre-set storage device. It cannot flexibly switch the transport target according to the actual construction needs. It cannot adapt to the mobile receiving needs of mortar trucks, nor can it quickly switch to other storage devices for diversion and storage. Its poor adaptability limits the application scenarios of the equipment.

[0004] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing integrated mortar mixing and conveying equipment. Utility Model Content

[0005] To solve the above problems, this utility model provides an integrated machine for mixing and conveying cementitious mortar, including a base plate, two vertical frames symmetrically installed on the base plate, two horizontal plates installed inside the vertical frames, and a semi-circular frame installed between the two horizontally corresponding horizontal plates, and the ports of the upper and lower semi-circular frames correspondingly form a mixing frame.

[0006] The top of the semi-circular frame at the top is equipped with a feed pipe.

[0007] The mixing frame contains a mixing unit for mixing mortar.

[0008] The bottom of the mixing frame is equipped with a discharge unit for discharging the mixed mortar.

[0009] Preferably, the stirring unit includes two circular grooves formed between the upper and lower semicircular frames, a rotating shaft is rotatably inserted in the circular grooves, several circular rings distributed along its extension are sleeved on the outside of the rotating shaft, and several blades distributed along its axis are installed on the outside of the circular rings.

[0010] Preferably, a drive assembly for driving the rotating shaft to rotate is installed on one side of the semicircular frame. The drive assembly includes two L-shaped slots symmetrically opened on one side of the two semicircular frames. An annular plate is rotatably installed in the L-shaped slot. A drive gear is installed on one side of the annular plate through the outer wall of the corresponding semicircular frame, and the two drive gears mesh with each other. A drive shaft is installed in the middle of the drive gear.

[0011] Preferably, one side of the rotating shaft has several drive slots, and one end of the drive shaft rotates through the inner wall of the semi-circular frame and has several drive keys located in the corresponding drive slots.

[0012] Preferably, a drive motor is mounted on one side of the upper semi-circular frame via a motor mount, and a drive gear is mounted on the main shaft of the drive motor, with the drive gear meshing with a drive gear on one side.

[0013] Preferably, the discharge unit includes a discharge frame installed at the bottom of the lower semi-circular frame and communicating with its interior, a discharge valve installed between the discharge frame and the semi-circular frame, a discharge pipe installed through the bottom of the discharge frame, and a discharge component for diverting and discharging mortar installed at the bottom of the discharge pipe.

[0014] Preferably, the discharge assembly includes a horizontal pipe that runs through the bottom of the discharge pipe, with bent pipes installed on both sides of the horizontal pipe. A rotating rod located inside the horizontal pipe is inserted between the bent pipes and rotates together. A spiral blade is installed on the outside of the rotating rod, and one side of the rotating rod extends through the outer wall of the bent pipe.

[0015] Preferably, the two bottom horizontal plates are slidably connected to the corresponding vertical frames, and two symmetrically distributed hydraulic rods are installed on the bottom plate, with the telescopic shafts of the hydraulic rods connected to the corresponding top horizontal plates.

[0016] In summary, this application includes at least one of the following beneficial technical effects: I. This utility model uses a detachable upper and lower semi-circular frame to form a mixing frame, which is equipped with a horizontal plate that is slidably connected to the bottom plate hydraulic rod and the vertical frame. During maintenance, the hydraulic rod can drive the lower semi-circular frame to descend, so that the mixing frame can be quickly separated and the mixing unit can be exposed. This completely solves the problems of difficult cavity wall cleaning and complicated blade disassembly in traditional integrated equipment. Maintenance and parts replacement can be completed without disassembling the complex structure, which greatly shortens maintenance time, reduces project delays, and lowers long-term maintenance costs. II. This utility model uses a horizontal pipe, a bidirectional bend pipe, and a rotating rod with built-in spiral blades in the material discharge assembly. Combined with an external motor controlling the rotation of the rotating rod, the mortar can be conveyed through different bend pipes after entering the horizontal pipe by rotating the rod in both directions. It is suitable for mobile receiving of mortar trucks and diversion and storage of fixed equipment, which solves the limitations of traditional single output pipes, meets the needs of multi-area material supply in construction and batch storage in road maintenance, and improves the adaptability and overall efficiency of equipment operation.

[0024] The following combination Figures 1 to 5 The embodiments of this utility model will be described in detail below.

[0025] This application discloses an integrated cementitious mortar mixing and conveying machine for mortar mixing operations. Through a detachable mixing frame, the mixing unit and blades can be easily maintained and replaced, solving the problems of difficult maintenance and single conveying target of traditional mortar mixing equipment, improving the efficiency and adaptability of mortar mixing operations, and meeting diverse construction needs.

[0026] Example 1: Refer to Figure 1 and Figure 2 As shown, it includes a base plate 1, vertical frames 10, horizontal plates 11, semi-circular frames 12, feed pipe 13, stirring unit 2, discharge unit 4, and hydraulic rod 6. Two vertical frames 10 are symmetrically installed on the base plate 1. Two horizontal plates 11 are installed inside the vertical frames 10. A semi-circular frame 12 is installed between the two horizontally corresponding horizontal plates 11. The ports of the upper and lower semi-circular frames 12 form a stirring frame. The vertical frames 10 support the upper and lower semi-circular frames 12 through four horizontal plates 11.

[0027] The top of the upper semi-circular frame 12 is equipped with a feed pipe 13. Several feed pipes 13 can be connected to the port of an external feeding device. The external feeding device supplies raw materials (abbreviation of cementitious mortar raw materials) into the mixing frame through the feed pipes 13.

[0028] The mixing frame is equipped with a mixing unit 2 for mixing mortar. After the material enters the mixing frame, it is mixed by the mixing unit 2.

[0029] The bottom of the mixing frame is equipped with a discharge unit 4 for discharging the mixed mortar.

[0030] The two bottom horizontal plates 11 are slidably connected to the corresponding vertical frames 10. Two symmetrically distributed hydraulic rods 6 are installed on the bottom plate 1. The telescopic shafts of the hydraulic rods 6 are connected to the corresponding top horizontal plates 11. When maintenance is required on the inside of the mixing frame and the mixing unit 2, the two bottom horizontal plates 11 are lowered through the telescopic shafts of the hydraulic rods 6, thereby driving the two bottom horizontal plates 11 to lower within the vertical frames 10. This allows the lower semi-circular frame 12 to drive the mixing unit 2 to descend synchronously. The two semi-circular frames 12 are separated from each other, making it easier for maintenance personnel to perform internal maintenance.

[0031] Reference Figure 2 As shown, this is the mixing unit 2 used for mixing mortar; specifically, the mixing unit 2 includes a rotating shaft 20, a ring 21 and blades 22. Two circular grooves are respectively opened between the upper and lower semi-circular frames 12. The rotating shaft 20 is rotatably inserted in the circular groove. Several rings 21 distributed along its extension are sleeved on the outside of the rotating shaft 20. Several blades 22 distributed along its axis are installed on the outside of the rings 21.

[0032] When driven by an external force, the rotating shaft 20 can rotate in the circular groove. The rotating shaft 20 can drive the blades 22 through the ring 21 to stir and mix the raw materials in the stirring frame.

[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown, a drive assembly 3 for driving the rotating shaft 20 to rotate is installed on one side of the semicircular frame 12. Specifically, the drive assembly 3 includes an L-shaped groove 30, an annular plate 31, a drive gear 32, a drive shaft 33, a drive groove 34, a drive key 35, a drive motor 36, and a drive gear 37. Two L-shaped grooves 30 are symmetrically opened on one side of the two semicircular frames 12. An annular plate 31 is rotatably installed in the L-shaped groove 30. A drive gear 32 is installed on one side of the annular plate 31 through the outer wall of the corresponding semicircular frame 12.

[0034] Two drive gears 32 mesh with each other, and a drive shaft 33 is installed in the middle of the drive gears 32. That is, the annular plate 31 can rotate in the corresponding L-shaped groove 30. The L-shaped groove 30 can prevent the annular plate 31 from falling off due to lateral displacement during rotation, so that the annular plate 31 can support and limit the drive gears 32. When one drive gear 32 is driven by an external force, it can drive the annular plate 31 to rotate in the L-shaped groove 30, and it will also drive the other drive gear 32 to rotate in the opposite direction, so that the two drive gears 32 can drive the corresponding drive shaft 33 to rotate.

[0035] Several drive slots 34 are provided on one side of the rotating shaft 20, and one end of the drive shaft 33 rotates through the inner wall of the semi-circular frame 12 and is provided with several drive keys 35 located in the corresponding drive slots 34. The drive shaft 33 can drive the rotating shaft 20 to rotate through the cooperation of the drive keys 35 and the drive slots 34, so that the rotating shaft 20 can drive the blades 22 to stir the raw materials.

[0036] A drive motor 36 is mounted on one side of the upper semi-circular frame 12 via a motor mount. A drive gear 37 is mounted on the main shaft of the drive motor 36, and the drive gear 37 meshes with a drive gear 32 on one side. The drive motor 36 can drive the drive gear 32 on one side to rotate through the drive gear 37.

[0037] During subsequent maintenance, the upper and lower semicircular frames 12 separate, and the rotating shaft 20 and drive shaft 33 descend with the lower semicircular frame 12. The drive gear 37 no longer meshes with the drive gear 32, and the annular plate 31 is now located only in the L-shaped groove 30 within the lower semicircular frame 12. If the rotating shaft 20 needs to be disassembled, the operator can pull the rotating shaft 20 in the groove and move it away from the drive shaft 33, so that the drive key 35 is no longer located in the drive groove 34. Then, the operator can use external lifting equipment to lift the rotating shaft 20 from the semicircular frame 12, and then reinstall the new rotating shaft 20 in the groove, so that the drive key 35 is inserted into the drive groove 34 on one side of the new rotating shaft 20, thus completing the replacement. The replacement can be completed by driving the two semicircular frames 12 to close again.

[0038] Reference Figure 5 As shown, the discharge unit 4 is used to discharge the mixed mortar. Specifically, the discharge unit 4 includes a discharge frame 40, a discharge pipe 41, and a discharge assembly 5. The discharge frame 40 is installed at the bottom of the lower semi-circular frame 12 and is connected to its interior. A discharge valve (not shown in the figure) is installed between the discharge frame 40 and the semi-circular frame 12. The discharge valve is used to prevent the raw materials from falling into the discharge frame 40 before the mixing is completed. The discharge pipe 41 is installed through the bottom of the discharge frame 40, and the discharge assembly 5 is installed at the bottom of the discharge pipe 41.

[0039] That is, after the raw materials are mixed, the discharge valve is opened so that the raw materials in the mixing frame can enter the discharge frame 40 and then fall from the discharge frame 40 into the discharge assembly 5 through the discharge pipe 41.

[0040] Reference Figure 5 As shown, the discharge assembly 5 is used to divert and discharge mortar. Specifically, the discharge assembly 5 includes a horizontal pipe 50, a bend pipe 51, a rotating rod 52, and a spiral blade 53. The horizontal pipe 50 is installed through the bottom of the discharge pipe 41. Bend pipes 51 are installed on both sides of the horizontal pipe 50. The rotating rod 52 located inside the horizontal pipe 50 is rotatably inserted between the bend pipes 51. A spiral blade 53 is installed on the outside of the rotating rod 52, and one side of the rotating rod 52 extends through the outer wall of the bend pipe 51.

[0041] Material in the discharge pipe 41 can enter the horizontal pipe 50. Then, one side of the rotating rod 52 can be connected to the main shaft of the external drive motor 36, driving the rotating rod 52 to rotate. This causes the rotating rod 52 to move the material in the horizontal pipe 50 through the spiral blade 53, moving towards the bend 51 on one side. Furthermore, the rotating rod 52 can be switched between forward and reverse rotation according to the direction driven by the external drive motor 36, allowing the material in the horizontal pipe 50 to move towards the bends 51 in different directions. The two bends 51 can be connected to different storage devices, achieving the effect of controlling the forward and reverse rotation of the external drive motor 36 to drive the material to different storage devices.

[0042] During operation: First, connect the port of the external feeding device to the feed pipe 13 at the top of the upper semi-circular frame 12, and supply the cementitious mortar raw material into the mixing frame composed of the upper and lower semi-circular frames 12 through the feed pipe 13.

[0043] Step 2: Start the drive motor 36. The main shaft of the drive motor 36 drives the drive gear 37 to rotate. The drive gear 37 meshes with the drive gear 32 on one side of the transmission. The drive gear 32 then meshes with the drive gear 32 on the other side of the transmission, so that the two drive gears 32 rotate synchronously in opposite directions.

[0044] Step 3: When the drive gear 32 rotates, it drives the corresponding drive shaft 33 to rotate. The drive shaft 33, through the cooperation of the drive key 35 and the drive groove 34 on the rotating shaft 20, drives the rotating shaft 20 to rotate in the circular groove of the semi-circular frame 12. The blades 22 on the outer ring 21 of the rotating shaft 20 rotate accordingly, and mix the mortar raw materials in the mixing frame.

[0045] Step 4: After the mortar is mixed, open the discharge valve between the discharge frame 40 and the semi-circular frame 12. The mixed mortar enters the discharge frame 40 from the mixing frame and then flows into the horizontal pipe 50 of the discharge assembly 5 through the discharge pipe 41 at the bottom of the discharge frame 40.

[0046] Step 5: Connect one side of the rotating rod 52 to the main shaft of the external drive motor 36. According to the required conveying target, control the direction of the external drive motor 36 so that the rotating rod 52 drives the spiral blade 53 to rotate in the horizontal tube 50. The spiral blade 53 pushes the mortar in the horizontal tube 50 toward the corresponding bend 51 to realize the diversion and discharge of mortar.

[0047] Step 6: When maintenance is required on the inside of the mixing frame and the mixing unit 2, start the hydraulic rod 6 on the base plate 1. The telescopic shaft of the hydraulic rod 6 descends, causing the bottom horizontal plate 11 to slide within the vertical frame 10, so that the lower semi-circular frame 12 drives the mixing unit 2 to descend synchronously. The upper and lower semi-circular frames 12 separate, making it easier for maintenance personnel to perform maintenance operations.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
