Description

Technical Field

[0001] This utility model relates to the field of mortar mixing technology, and more specifically, to a high-efficiency mortar mixing device. Background Technology

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementing materials with water in a certain proportion. It is also called mortar or cement paste. Common types of mortar include cement mortar, mixed mortar, lime mortar, and clay mortar. A mortar mixer is a machine that mixes cement, sand and gravel aggregates and water to make mortar mixture.

[0003] During the mixing process of mortar, the powder itself has a certain degree of adhesion to the wall, and the damp material will further increase the adhesion of the powder to the wall. During the mixing process, some of the mortar will adhere to the inner wall of the mixing tank. As the mixing continues, it will become thicker and thicker. Over time, it will form lumps on the inner wall and erode the mixing tank. When feeding material again, the mortar lumps remaining on the inner wall will be mixed into the new mortar, affecting the quality of the mortar. Moreover, the mortar adhering to the inner wall of the mixing tank for a long time will cause it to stick to the mixing tank, making it difficult to remove later and affecting the subsequent use of the mixing tank. How to invent an efficient mortar mixing device to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency mortar mixing device, which aims to improve the problem that residual mortar blocks on the inner wall will affect the quality of the mortar, and that mortar is difficult to remove after long-term adhesion, thus affecting subsequent use.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a high-efficiency mortar mixing device, including a mixing drum and support legs. The mixing drum is connected to a discharge pipe and a feed pipe. The upper end of the mixing drum is provided with a cover plate and a motor. The inside of the mixing drum is provided with a rotating shaft, and the rotating shaft is connected to a first mixing rod, a scraper, and a second mixing rod. The inside of the mixing drum is provided with a water spray pipe, and the outside of the mixing drum is provided with a water distribution pipe and a solenoid valve. The side wall of the cover plate is provided with an arc-shaped sliding plate. One end of the first mixing rod is provided with an impact rod and a telescopic spring. The impact rod is connected with a vertical rod, an impact ball, and a squeezing rod. One end of the first mixing rod is provided with a pressure sensor.

[0007] Preferably, the side wall of the mixing drum is fixedly connected to the support leg, the lower side wall of the mixing drum is fixedly connected to the discharge pipe, the upper end of the mixing drum is detachably connected to the cover plate, the upper side wall of the cover plate is fixedly connected to the feed pipe, the upper end of the cover plate is fixedly connected to the motor, and the lower side wall of the cover plate is fixedly connected to the arc-shaped sliding plate. Several arc-shaped sliding plates are provided, and the several arc-shaped sliding plates are arranged in a circumferential array about the cover plate.

[0008] Preferably, the water distribution pipe is semi-circular in shape, and the water distribution pipe is fixedly connected to the water inlet pipe. The water inlet pipe is fixedly connected to the solenoid valve, and both ends of the water distribution pipe pass through the side wall of the mixing drum and are fixedly connected to the water spray pipe.

[0009] Preferably, the upper end of the rotating shaft is vertically connected to the side wall of the cover plate and fixedly connected to the motor. The outer wall of the rotating shaft is fixedly connected to the stirring rod one, the scraper and the stirring rod two respectively. The scraper is located outside the stirring rod one and the stirring rod two. A scraper is fixedly connected to the outer wall of the rotating shaft. The scraper is located below the stirring rod two.

[0010] Preferably, the end of the stirring rod away from the rotating shaft is provided with a mounting groove, and the inner wall of the mounting groove is fixedly connected to the pressure sensor.

[0011] Preferably, one end of the impact rod is movably connected to an impact ball, and the other end of the impact rod is provided with a movable groove. The inner wall of the movable groove is slidably connected to the outer wall of the stirring rod. The inner wall of the movable groove at the end away from the opening is fixedly connected to the extrusion rod, and the outer wall of the impact rod is fixedly connected to the upright rod.

[0012] Preferably, the telescopic spring is located inside the movable groove, and its two ends are fixedly connected to the inner wall of the movable groove and the inner wall of the mounting groove, respectively. The two ends of the telescopic spring are located outside the compression rod and the pressure sensor, respectively.

[0013] The beneficial effects of this utility model are:

[0014] The motor and shaft drive the first stirring rod, scraper, and second stirring rod to thoroughly mix the materials. The scraper scrapes the inner wall of the mixing drum to reduce material adhesion, and the scraper scrapes the bottom wall of the mixing drum to prevent material accumulation or adhesion during discharge, thus avoiding damage to the mixing drum. In addition, as the shaft rotates, the arc-shaped sliding plate squeezes the upright rod, which in turn moves the impact rod to one side of the shaft. At the same time, it compresses the telescopic spring and drives the squeezing rod to squeeze the pressure sensor, triggering the solenoid valve to open. The inner wall of the mixing drum is then rinsed through the water spray pipe. When the upright rod separates from the arc-shaped sliding plate, the telescopic spring quickly drives the impact rod to reset through elastic potential energy. This causes the impact ball to strike the inner wall of the mixing drum, causing the inner wall of the mixing drum to vibrate and quickly slide off any adhering material. This, combined with the scraper, cleans the drum, thus preventing material adhesion and ensuring the quality of the next mortar mixing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example, refer to Figures 1-7 A high-efficiency mortar mixing device includes a mixing drum 3 and support legs 1. The mixing drum 3 is connected to a discharge pipe 2 and a feed pipe 6. The upper end of the mixing drum 3 is provided with a cover plate 5 and a motor 7. The inside of the mixing drum 3 is provided with a rotating shaft 14, which is connected to a first mixing rod 11, a scraper 12 and a second mixing rod 13. The inside of the mixing drum 3 is provided with a water spray pipe 17. The outside of the mixing drum 3 is provided with a water distribution pipe 4 and a solenoid valve 9.

The impact rod 15 is connected to a vertical rod 16, an impact ball 19 and a pressing rod 24. One end of the first mixing rod 11 is provided with a pressure sensor 23.

[0026] Furthermore; the side wall of the mixing drum 3 is fixedly connected to the support leg 1, the lower side wall of the mixing drum 3 is fixedly connected to the discharge pipe 2, the upper end of the mixing drum 3 is detachably connected to the cover plate 5, the upper side wall of the cover plate 5 is fixedly connected to the feed pipe 6, the upper end of the cover plate 5 is fixedly connected to the motor 7, the lower side wall of the cover plate 5 is fixedly connected to the arc-shaped slide plate 10, and there are several arc-shaped slide plates 10 arranged in a circular array about the circumference of the cover plate 5; the upper end of the rotating shaft 14 vertically penetrates the side wall of the cover plate 5 and is fixedly connected to the motor 7, the outer wall of the rotating shaft 14 is fixedly connected to the first stirring rod 11, the scraper 12 and the second stirring rod 13 respectively, the scraper 12 is located outside the first stirring rod 11 and the second stirring rod 13, and the outer wall of the rotating shaft 14 is fixedly connected to the scraper 18, which is located below the second stirring rod 13.

[0027] It should be noted that: relevant materials are added into the mixing drum 3 through the feed pipe 6, and the rotating shaft 14 is driven to rotate by the motor 7. During the rotation of the rotating shaft 14, the first mixing rod 11, the scraper 12 and the second mixing rod 13 are also rotated. The materials are fully mixed by the first mixing rod 11 and the second mixing rod 13. During the mixing process, the inner wall of the mixing drum 3 is scraped by the scraper 12 to reduce the adhesion of materials. When the mortar is mixed and needs to be discharged, the discharge pipe 2 can be opened to discharge the slurry. At the same time, the bottom wall of the mixing drum 3 is scraped by the scraper 18 to prevent the materials from accumulating or adhering to the bottom wall of the mixing drum 3 during the discharge process, thereby causing damage to the mixing drum 3.

[0028] Reference Figures 2-7 Furthermore, the stirring rod 11 has an installation groove 22 at one end away from the rotating shaft 14, and the inner wall of the installation groove 22 is fixedly connected to the pressure sensor 23; one end of the impact rod 15 is movably connected to the impact ball 19, and the other end of the impact rod 15 has an movable groove 21, the inner wall of the movable groove 21 is slidably connected to the outer wall of the stirring rod 11, the inner wall of the movable groove 21 away from the opening is fixedly connected to the extrusion rod 24, and the outer wall of the impact rod 15 is fixedly connected to the upright rod 16; the telescopic spring 20 is located inside the movable groove 21, and the two ends of the telescopic spring 20 are fixedly connected to the inner wall of the movable groove 21 and the inner wall of the installation groove 22, respectively, and the two ends of the telescopic spring 20 are located outside the extrusion rod 24 and the pressure sensor 23, respectively; the water distribution pipe 4 is semi-circular, and the water distribution pipe 4 is fixedly connected to the water inlet pipe 8, which is fixedly connected to the solenoid valve 9, and the two ends of the water distribution pipe 4 pass through the side wall of the stirring drum 3 and are fixedly connected to the water spray pipe 17.

[0029] It should be noted that during the rotation of the stirring rod 11, the impact rod 15 can move synchronously, thereby improving the mixing effect. During material discharge, the height of the material inside the mixing drum 3 will gradually decrease. When the material height is lower than the impact rod 15, the rotation of the rotating shaft 14 will cause the arc-shaped sliding plate 10 to squeeze the upright rod 16, thereby driving the impact rod 15 to move towards one side of the rotating shaft 14, and simultaneously compressing the telescopic spring 20. When the impact rod 15 moves to its final end, it will drive the squeezing rod 24 to squeeze the pressure sensor 23. The pressure sensor 23 is connected to the solenoid valve 9, so when the pressure sensor 23 is under pressure, the solenoid valve 9 opens, and water flows through the water inlet pipe 8 and the water distribution pipe 4 to the inside of the spray pipe 17, thereby rinsing the inner wall of the mixing drum 3. After the upright rod 16 separates from the arc-shaped sliding plate 10, the telescopic spring 20 quickly drives the impact rod 15 to reset through elastic potential energy, thereby causing the impact ball 19 to impact the inner wall of the mixing drum 3. This causes the inner wall of the mixing drum 3 to vibrate, quickly sliding off the attached material and cleaning it with the scraper 12, thus preventing material adhesion and ensuring the quality of the next mortar mixing. When the impact rod 15 resets, the squeezing rod 24 and the pressure sensor 23 separate, and the water spray pipe 17 stops working, reducing waste. In addition, during the mixing process, when the mortar height is higher than the impact rod 15, the impact effect of the impact ball 19 is poor, or the resistance of the mortar cannot produce a vibration effect. Furthermore, the water inlet pipe 8 can be kept closed during mixing to prevent water from continuously entering the interior of the mixing drum 3 and affecting the quality of the mortar.

[0030] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
