Abstract
Description
Technical Field
[0001] The invention relates to the technical field of household kitchens, and in particular to an anti-clogging mortar mixing and stirring device. Background Art
[0002] Mortar is composed of cement, sand, water and additives. These materials are separated from each other when not mixed. By mixing, cement particles can be evenly dispersed in the mixture of sand and water. The mixed mortar has good workability, including fluidity, water retention and cohesion. Fluidity enables the mortar to flow and fill smoothly in the formwork or on the surface of the base during construction.
[0003] In the process of mortar mixing, generally, each component raw material is first injected into the mixing device through a hopper. After being fully mixed, the mortar is discharged from the mixing device outlet for use. However, in the actual operation process, there are two shortcomings. On the one hand, in the process of raw materials entering the mixing device from the hopper, since the raw materials are not evenly mixed, the fluidity of various raw materials is different. Especially for automated mixing equipment, since the raw materials will be stored in the hopper for a period of time, raw materials of different particle sizes will form layers. When raw materials with poor fluidity accumulate, it is easy to cause the hopper outlet to be blocked. On the other hand, the cross-sectional area of the mixing device outlet is generally set to be small. Coupled with the influence of a series of factors such as raw material ratio and mixing effect, it is easy to cause mortar to be blocked at the mixing device outlet. Summary of the invention

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] Embodiment 1:
[0024] Please see attached Figure 1 -Attached Figure 6The embodiment of the present invention provides an anti-clogging mortar mixing device, including a supporting steel frame 10, the supporting steel frame 10 is in a stepped shape, and a stirring drum 20 is arranged on a side with a lower height, the stirring drum 20 is placed obliquely, and its opening is inclined upward, and the stirring drum 20 is driven to rotate along its central axis by a driving device 60, and a spiral conveying component 30 is arranged in the stirring drum 20, and the spiral conveying component 30 rotates synchronously with the stirring drum 20. When the rotation direction of the stirring drum 20 is opposite to the spiral direction of the spiral conveying component 30, the mortar raw materials in the stirring drum 20 are retained in the stirring drum 20, and when the rotation direction of the stirring drum 20 is the same as the spiral direction of the spiral conveying component 30, the stirring drum The mortar raw materials in the cylinder 20 are transported to the outside along the path formed by the spiral conveying component 30. An upper hopper 40 is provided on the upper part of the side with a higher height of the supporting steel frame 10. The discharge port of the upper hopper 40 corresponds to the opening of the mixing drum 20, so that the mortar raw materials fall into the mixing drum 20 from the discharge port of the upper hopper 40. An opening and closing mechanism 70 is also provided at the discharge port of the upper hopper 40 for controlling the opening and closing state of the discharge port of the upper hopper 40. A pre-mixing device 80 is provided in the middle of the upper hopper 40 for pre-mixing the mortar raw materials in the upper hopper 40. A discharge hopper 50 is provided below the upper hopper 40. The upper opening of the discharge hopper 50 is located below the opening of the mixing drum 20 for receiving the mixed mortar discharged from the mixing drum 20. The spiral conveying component 30 is composed of a spiral blade 301, one end of the spiral blade 301 contacts the inner bottom wall of the stirring drum 20, and the other end spirally surrounds the inner wall of the stirring drum 20 and extends to the opening of the stirring drum 20, and the spiral blade 301 adopts a shaftless hollow structure.
[0025] It should be noted that the bottom wall of the stirring drum 20 is connected to the driving device 60, and the outer wall cooperates with the supporting steel frame 10. The stirring drum 20 is supported by the supporting steel frame 10, so that the stirring drum 20 is placed at an angle, and the outer wall of the stirring drum 20 can rotate relative to the supporting steel frame 10.
[0026] In order to realize the automatic operation of the device, a loading hopper 40 for storing raw materials and automatically loading is arranged above the opening of the mixing drum 20. Automatic loading is to control the opening and closing state of the discharge port of the loading hopper 40 through the opening and closing mechanism 70, so that the mortar raw materials in the loading hopper 40 fall into the mixing drum 20 under the action of gravity when it is opened, and prevent the leakage of the mortar raw materials when it is closed.
[0027] The above steps are all controlled by the control system that is matched with the mortar mixing device. At the same time, the mixing process is also controlled by the control system, namely:
[0028] When in the stirring step, the control system drives the driving device 60 to rotate in the opposite direction to the rotation direction of the spiral blade 301 to ensure that the mortar raw materials scattered in the mixing drum 20 will not leak out, and then perform forward and reverse cycle operation at a preset frequency, that is, forward and reverse rotations are performed alternately at a preset frequency, so that a part of the mortar raw materials in the mixing drum 20 is continuously scattered and mixed, while another part of the mortar raw materials are continuously scattered and recombined along the path of the spiral blade 30 under the action of the spiral blade 30 and the action of the raw materials' own gravity, thereby improving the stirring and mixing efficiency; when in the discharging step of the mixing drum 20, the control system drives the driving device 60 to rotate in the same direction as the rotation direction of the spiral blade 30, so that the mortar raw materials are finally discharged from the opening of the mixing drum 20 under the conveying action of the spiral blade 30.
[0029] By setting the pre-mixing device 80 in the upper hopper 40, the mortar raw materials stored in the upper hopper 40 are continuously stirred and turned during the cycle, thereby avoiding the problem of raw material stratification, solving the problem of raw material accumulation blocking the discharge port of the upper hopper 40, and realizing the pre-mixing of the mortar raw materials, reducing the pressure of subsequent mixing and stirring, and improving the mixing efficiency. At the same time, through the cooperation of the mixing drum 20 and the spiral conveying component 30, on the one hand, the rotation of the mixing drum 20 drives the mortar raw materials therein to continuously perform parabolic motion, and with the periodic forward and reverse program, the mortar raw materials are continuously dispersed and combined under the action of their own gravity and the conveying force of the spiral conveying component 30, thereby improving the mixing and stirring effect; on the other hand, since the opening of the mixing drum 20 is both a feed port and a discharge port, the large diameter cooperates with the conveying action of the spiral conveying component 30, so that the mortar that has been mixed and mixed can be discharged smoothly, solving the problem that the discharge port of the existing mixing equipment has a small cross-sectional area and is easy to be blocked.
[0030] The driving device 60 includes a rotating shaft 601, one end of which is embedded in and fixedly connected to the center of a fixed disk 602, and a side wall of the fixed disk 602 is fixedly connected to the bottom wall of the stirring drum 20. The other end of the rotating shaft 601 is fixedly connected to the output end of a reducer 603, and the input end of the reducer 603 is fixedly connected to the output end of a motor 604. The outer walls of both are fixedly connected to the supporting steel frame 10, and the outer wall of the rotating shaft 601 is connected to the supporting steel frame 10 through a bearing seat 605.
[0031] The output of the motor 1 604 is converted by the reducer 603 to drive the rotating shaft 601 to rotate, thereby driving the mixing drum 20 to rotate.
[0032] The opening and closing mechanism 70 includes a guide groove 701, which is located below the discharge port of the upper hopper 40, and the two are rotatably connected. One side of the guide groove 701 is connected to the outer wall of the upper hopper 40 through a cylinder 702. When the cylinder 702 pushes the guide groove 701 to rotate until the guide groove 701 closes the discharge port of the upper hopper 40, the discharge port of the upper hopper 40 is closed. The cylinder 702 pulls the guide groove 701 to rotate in the opposite direction until the groove direction of the guide groove 701 coincides with the discharge direction of the discharge port of the upper hopper 40. At this time, the discharge port of the upper hopper 40 is opened, and the guide groove 701 guides the mortar raw materials into the mixing drum 20.
[0033] The two ends of the cylinder 702 are rotatably connected to the outer wall of the upper hopper 40 and the guide groove 701 respectively, so that the guide groove 701 can be driven to rotate by the extension and contraction of the cylinder 702. When the guide groove 701 is expanded and the direction of the groove opening coincides with the discharge direction of the discharge port of the upper hopper 40, the guide groove 701 also guides the moving path of the mortar raw materials to ensure that the mortar raw materials enter the mixing drum 20.
[0034] The pre-mixing device 80 includes a stirring rod 801, which has a crankshaft-like structure. Its curved portion is located at the lower part of the upper hopper 40 near the discharge port, and its two ends respectively penetrate and are rotatably connected to two symmetrical side walls of the upper hopper 40. One end is also fixedly connected to the output end of motor 2 802, and the outer wall of motor 2 802 is fixedly connected to the supporting steel frame 10.
[0035] The second motor 802 drives the stirring rod 801 to rotate. Since the stirring rod 801 is a crankshaft structure, the curved portion performs a larger circular motion with the rotation axis of the stirring rod 801 as the center during rotation, thereby achieving stirring of the raw materials.
[0036] At the same time, the pre-stirring device 80 can also adopt the following scheme, namely:
[0037] The pre-mixing device 80 includes a stirring shaft 803, and a stirring paddle 804 is fixedly connected to the outer wall of the stirring shaft 803. The stirring paddle 804 is located at the lower part of the upper hopper 40 near the discharge port. Both ends of the stirring shaft 803 respectively penetrate and are rotatably connected to two symmetrical side walls of the upper hopper 40, and one end is also fixedly connected to the output end of motor three 805. The outer wall of motor three 805 is fixedly connected to the supporting steel frame 10.
[0038] The motor 3 805 rotates to drive the stirring shaft 803 to rotate, and then drives the stirring paddle 804 to rotate to stir the raw materials.
[0039] Embodiment 2:
[0040] Please refer to the attached Figure 7On the basis of the above embodiment, the present embodiment further improves the spiral conveying component 30 in the above embodiment, namely: the spiral conveying component 30 is composed of two coaxial spiral blades 301, one end of one spiral blade 301 is in contact with the inner bottom wall of the stirring drum 20, and the other end spirally surrounds along the inner wall of the stirring drum 20 and extends to the opening of the stirring drum 20, and the spiral blade 301 adopts a shaftless hollow structure, and the other spiral blade 301 is formed by rotating 180° with the previous spiral blade 301 as the starting point and the central axis of the stirring drum 20 as the center.
[0041] The spiral conveying component 30 is formed by two coaxial spiral blades 301. The double spiral structure makes the stirring effect on the raw materials more complex and multi-dimensional, and makes the movement trajectory of the raw materials more varied, thereby further improving the stirring effect. At the same time, by prefabricating parameters such as the pitch, spiral angle, and blade thickness of the blades, for example, for materials with good fluidity, the pitch can be appropriately increased to facilitate efficient transportation; when processing sticky and easily agglomerated materials, a smaller pitch and thicker blades are used to enhance the pushing and stirring force, thereby improving the discharge effect and further reducing the probability of blockage.
[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
