Description

Technical Field

[0001] The present application relates to the technical field of dry-mix mortar, and in particular to a dry-mix mortar mixing device. Background Art

[0002] Dry-mixed mortar refers to a granular or powdered material that is physically mixed in a certain proportion with dried and screened aggregates, inorganic cementitious materials and additives, and can be used directly after adding water and mixing.

[0003] The existing patent (publication number: CN216609514U) discloses a dry-mix mortar mixer, including a bracket, a drive motor, a speed transmission box, a horizontal mixing drum, a blade mixing part and a feed pipe, wherein the horizontal mixing drum is fixedly arranged on the top of the bracket, the speed transmission box is arranged on one side of the horizontal mixing drum and the input end is connected to the drive motor, the output end of the speed transmission box is connected to the blade mixing part in the horizontal mixing drum, and a feed pipe is arranged at the bottom of the horizontal mixing drum, the blade mixing part includes a rotating shaft and a Mobius mixing blade, and a plurality of the Mobius mixing blades are linearly arranged along the central axis of the rotating shaft.

[0004] A dry-mix mortar mixer pointed out in the above patent uses a Mobius mixing blade instead of a traditional flaky mixing blade, and cooperates with a spiral mixing blade to realize internal and external circulation mixing, so that the material mixing is more sufficient and the mixing efficiency is higher. However, in actual use of the above device, since the dry-mix mortar raw materials are in a dry state during mixing, dust will be generated during the mixing process. Since the upper end of the horizontal mixing drum is not closed, dust will float out of the horizontal mixing drum during the mixing process, which will not only pollute the environment, but may also be harmful to the health of the operator. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a dry-mix mortar mixing device with advantages such as easy disassembly. It solves the problem that in actual use of the dry-mix mortar mixer, dust will be generated during the mixing process because the dry-mix mortar raw materials are in a dry state during mixing. Since the upper end of the mixing drum is not closed, dust will float out of the mixing drum during the mixing process, which will not only pollute the environment, but may also endanger the health of the operator.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a dry-mix mortar mixing device, comprising a mixing box and a rotating plate, one end of the rotating plate is fixedly connected to a circular tooth plate, the rotating plate is in contact with the mixing box and is slidably connected to the surface of the mixing box, and one side of the rotating plate is fixedly connected to a mounting plate.

[0007] The lower end of the mixing box is provided with a discharge port corresponding to the rotating plate, the lower end of the mixing box is fixedly connected to four legs distributed in a matrix array, the upper end of the mixing box is fixedly connected to a connecting cylinder, the upper end of the connecting cylinder is fixedly connected to a feed hopper, two hinge door closers are fixedly connected to both sides of the interior of the connecting cylinder, two hinge door closers on the same side of the four hinge door closers are commonly fixedly connected to the surfaces of baffles, the inner wall of the connecting cylinder is fixedly connected to two blocks, and the upper ends of the baffles are abutted against the lower ends of the blocks.

[0008] Through the above scheme, baffles are rotatably connected to both sides of the connecting cylinder through hinge door closers. When in use, when the raw materials are poured into the feed hopper, the baffles will rotate around the hinge door closers under the action of gravity, so that the raw materials fall from between the two baffles into the inside of the mixing box. When the raw materials are added, the baffles are no longer subjected to force. At this time, the hinge door closer will drive the two baffles to rotate upward until the upper surfaces of the two baffles contact the lower surfaces of the baffles. At this time, the two baffles will close the connecting cylinder, and during the mixing process, dust can be minimized from floating out of the mixing box during the mixing process, causing pollution to the environment, while reducing harm to the health of operators.

[0009] Furthermore, circular slide rails are fixedly connected to both side surfaces of the mixing box, two sliding blocks are slidably sleeved on the two circular slide rail surfaces, and the mounting plate and the circular toothed plate are connected to the sliding blocks by bolts.

[0010] Through the above scheme, the combination of the circular slide rail and the slider provides a sliding adjustment function for the mounting plate and the circular toothed plate, and the mounting plate and the circular toothed plate can slide on the circular slide rail to adjust their relative positions with the mixing box.

[0011] Furthermore, a rotating column is rotatably connected to a surface of one side of the mixing box close to the circular tooth plate, and a driven wheel is fixedly connected to one end of the rotating column, and the driven wheel is meshed with the circular tooth plate.

[0012] Through the above scheme, when in use, the rotation of the driven wheel will drive the circular tooth plate to move, thereby driving the rotating plate to move, and further realizing the opening and closing of the discharge port.

[0013] Furthermore, a mounting frame is fixedly connected to the surface of one end of the mixing box close to the circular tooth plate, and a first motor is fixedly connected to the surface of the mounting frame.

[0014] Through the above solution, the design of the mounting frame not only provides a platform for installing the motor, but also ensures the stability of the motor during operation.

[0015] Furthermore, the output end of the first motor extends into the interior of the mounting frame and is fixedly connected to a driving wheel, and the driving wheel is meshed with a driven wheel.

[0016] Through the above solution, the first motor is started, the first motor drives the driving wheel to rotate, and then drives the driven wheel to rotate synchronously through the driving wheel.

[0017] Furthermore, a second motor is fixedly connected to one end of the mixing box, and an output end of the second motor passes through a side wall of the mixing box and is fixedly connected to a rotating roller.

[0018] Through the above solution, during use, the second motor is started, and the second motor drives the rotating roller to rotate synchronously with the rotating shaft of the second motor.

[0019] Furthermore, four groups of fixing frames are fixedly connected to the surface of the rotating roller, wherein each group is composed of two fixing frames distributed in a linear array, and a stirring frame is fixedly connected inside each of the fixing frames.

[0020] Through the above scheme, through the design of the fixed frame and the stirring frame, the mortar raw materials can be more effectively stirred when the rotating roller rotates. The design of the stirring frame can increase the contact area between the mortar and the stirring device, thereby improving the stirring efficiency.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The dry-mixed mortar mixing device is connected with baffles by rotating hinge door closers on both sides of the connecting tube. When in use, when the raw materials are poured into the feed hopper, the baffles will rotate around the hinge door closers under the action of gravity, so that the raw materials fall from between the two baffles into the inside of the mixing box. When the raw materials are added, the baffles are no longer subjected to force. At this time, the hinge door closer will drive the two baffles to rotate upward until the upper surfaces of the two baffles contact the lower surface of the block. At this time, the two baffles will close the connecting tube, so that dust can be minimized from floating out of the mixing box during the mixing process to cause pollution to the environment, while reducing harm to the health of operators.

[0033] See also Figure 1 , Figure 2 and Figure 3 A discharge port 7 corresponding to the rotating plate 11 is provided at the lower end of the mixing box 1, four legs 2 distributed in a matrix array are fixedly connected to the lower end of the mixing box 1, a connecting cylinder 3 is fixedly connected to the upper end of the mixing box 1, a feed hopper 4 is fixedly connected to the upper end of the connecting cylinder 3, two hinge door closers 5 are fixedly connected to both sides of the inside of the connecting cylinder 3, two hinge door closers 5 on the same side of the four hinge door closers 5 are commonly fixedly connected to the surface of a baffle 6, two blocks 22 are fixedly connected to the inner wall of the connecting cylinder 3, and the upper end of the baffle 6 abuts against the lower end of the block 22.

[0034] See also Figure 4 , a rotating column 13 is rotatably connected to the surface of one side of the mixing box 1 close to the circular toothed plate 10, and a driven wheel 14 is fixedly connected to one end of the rotating column 13, and the driven wheel 14 is meshed with the circular toothed plate 10. When in use, the rotation of the driven wheel 14 will drive the circular toothed plate 10 to move, thereby driving the rotating plate 11 to move, and further realizing the opening and closing of the discharge port 7. A mounting frame 15 is fixedly connected to the surface of one end of the mixing box 1 close to the circular toothed plate 10, and a first motor 16 is fixedly connected to the surface of the mounting frame 15. The design of the mounting frame 15 not only provides a platform for motor installation, but also ensures the stability of the motor during operation. The output end of the first motor 16 extends into the interior of the mounting frame 15 and is fixedly connected to a driving wheel 17, which is meshed with the driven wheel 14. When the first motor 16 is started, the first motor 16 will drive the driving wheel 17 to rotate, and then the driven wheel 14 is driven to rotate synchronously through the driving wheel 17.

[0035] See also Figure 1 and Figure 2 A second motor 18 is fixedly connected to one end of the mixing box 1, and an output end of the second motor 18 passes through the side wall of the mixing box 1 and is fixedly connected to a rotating roller 19. During use, the second motor 18 is started, and the second motor 18 drives the rotating roller 19 to rotate synchronously with the rotating shaft of the second motor 19. Four groups of fixed frames 20 are fixedly connected to the surface of the rotating roller 19, each group of which is composed of two fixed frames 20 distributed in a linear array, and a stirring frame 21 is fixedly connected to the inside of the multiple fixed frames 20. Through the design of the fixed frame 20 and the stirring frame 21, the mortar raw materials can be more effectively stirred when the rotating roller 19 rotates. The design of the stirring frame 21 can increase the contact area between the mortar and the stirring device, thereby improving the stirring efficiency.

[0036] In this embodiment, when in use, when the raw materials are poured into the feed hopper 4, the baffle 6 will rotate around the hinge door closer 5 under the action of gravity, so that the raw materials fall from between the two baffles 6 into the inside of the mixing box 1. When the raw materials are added, the baffle 6 is no longer subjected to force. At this time, the hinge door closer 5 will drive the two baffles 6 to rotate upward until the upper surfaces of the two baffles 6 contact the lower surface of the block 22. At this time, the two baffles 6 will close the connecting tube 3, which can minimize the dust from floating out of the mixing box 1 during the mixing process, causing pollution to the environment, and at the same time reduce the harm to the health of the operator.

[0037] The working principle of the above embodiment is:

[0038] The operator pours the raw materials of the dry-mixed mortar into the feed hopper 4. When the raw materials touch the baffle 6, due to the effect of gravity, the baffle 6 will rotate around the axis of the hinge door closer 5, thereby opening a channel so that the raw materials can smoothly fall into the mixing box 1. When the raw materials are completely poured in, the baffle 6 is no longer pressed by the gravity of the raw materials. At this time, the hinge door closer 5 will use its spring force or mechanical force to drive the baffle 6 to rotate upward until the upper surface of the baffle 6 is in close contact with the lower surface of the stopper 22. In this way, the connecting tube 3 is closed by the two baffles 6 to form a closed space, and then the second motor 18 is started. The machine 18 drives the rotating roller 19 to start rotating. The stirring frame 21 fixed on the surface of the rotating roller 18 continuously stirs the mortar raw materials as the rotating roller 19 rotates to ensure that the raw materials are fully mixed. After the stirring is completed, the first motor 16 is started. The first motor 16 drives the driving wheel 17 to rotate. The driving wheel 17 is meshed with the driven wheel 14, so the driven wheel 14 also starts to rotate. The rotation of the driven wheel 14 will drive the circular toothed plate 10 meshed with it to move, and then drive the rotating plate 11 to slide on the mixing box 1. When the rotating plate 11 moves to a suitable position, the discharge port 7 is opened, and the mortar can be discharged from the discharge port 7 smoothly.
