Description

Technical Field

[0001] This utility model relates to the technical field of mortar mixers, specifically to a desert sand composite cement mortar mixer. Background Technology

[0002] Cement mortar mixers are crucial equipment in cement preparation experiments. The mixing quality directly impacts the performance and application effects of the subsequent materials. Traditional mixing equipment presents several problems when mixing desert sand composite cement mortar. Firstly, the mixing tank lacks an effective fixing device during mixing, and the strong forces generated can easily cause it to rotate or shift. This not only affects the uniformity of mixing but may also lead to equipment malfunctions or even safety accidents. Secondly, air bubbles are easily generated within the desert sand composite cement mortar during mixing, and traditional mixing equipment lacks a dedicated degassing device. Residual air bubbles can create pores within the material, reducing its strength and durability. Furthermore, the mixing drive mechanism and mixing tank design of traditional equipment are not flexible enough, making it difficult to easily adjust and replace them according to different mixing needs, thus limiting the equipment's scope of application and efficiency. Therefore, those skilled in the art propose a technical solution for a desert sand composite cement mortar mixer to address these issues. Utility Model Content

The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0016] Example 1: A desert sand composite cement mortar mixer, comprising a mixing drive mechanism 1 and a mixing tank mechanism 2. In the mixing drive mechanism 1, a base plate is fixed to the middle section of the upper surface of the base 101, and a support frame 103 is fixed to the rear side. Two crossbeams 104 are fixed to the top of the support frame 103, and a top plate is fixed between the crossbeams 104. A screw rod 110 passes through the top plate and is fixedly connected to the end of the screw rod 110 above the top plate. Its bottom end is rotatably connected to the middle section of the upper surface of the base plate. The bottom end of the guide rod 102 is fixed to the left and right sides of the upper surface of the base plate, and its top end is close to the crossbeam 104. The T-shaped support plate 107 has a T-shaped cross section, and through holes are opened on the left and right sides of the rear side for the guide rod 102 to pass through. A sliding plate is installed in the through hole. The moving bearing has a nut that is fitted to the outer thread of the lead screw 110 in the middle section of the rear side. Rotating the lead screw 110 by the handwheel 105 can drive the T-shaped support plate 107 to move up and down on the outer ring of the guide rod 102. The top of the T-shaped support plate 107 is fixed with a motor 106. The rear side of the housing of the motor 106 is fixed with a bracket. The bottom end of the bracket is fixedly connected to the upper surface of the T-shaped support plate 107. The output shaft of the motor 106 is connected to the agitator 109 through a coupling. The bottom surface of the T-shaped support plate 107 is fixedly connected with a tank cover 108 that is fitted to the upper port of the tank body 207. The tank cover 108 has a round hole inside for the agitator 109 to pass through and rotate.

[0017] In the mixing tank mechanism 2, a square groove 201 is fixed to the front side of the upper surface of the base 101, and a magnetic disk 203 is fixed to its upper surface. A plum blossom-shaped groove is opened on the upper surface of the magnetic disk 203. The tank body 207 is located above the square groove 201, and a circular groove 206 is fixed to the bottom surface. Four vibration motors 205 are fixed in a ring array on the lower surface of the circular groove 206. A support plate 204 is fixed to the bottom end face of the tank body 207. A plum blossom-shaped magnetic piece 202 is fixed to the bottom surface of the support plate 204. The plum blossom-shaped magnetic piece 202 and the magnetic disk 203 are magnetically attracted to each other. A wiring groove 208 is provided on the rear side of the bottom of the tank body 207 to provide a power line for the vibration motors 205 to pass through. In use, place the tank 207 on the square groove 201 so that the plum blossom-shaped magnet 202 is attracted to the plum blossom-shaped groove of the magnet disk 203, restricting the axial and vertical movement of the tank 207. Rotate the screw 110 to lower the T-shaped support plate 107, and cover the tank 207 with the lid 108. The stirring paddle 109 extends into the tank 207. Start the motor 106 to drive the stirring paddle 109 to stir, and at the same time start the vibration motor 205 to expel air bubbles.

[0018] Example 2: A desert sand composite cement mortar mixer. The base 101 of the mixing drive mechanism 1 is thickened to enhance stability. The upright frame 103 is firmly welded to the base 101, and the crossbeam 104 is also welded to the upright frame 103. The guide rod 102 has a smooth surface to ensure smooth sliding of the T-shaped support plate 107. The nut of the T-shaped support plate 107 fits tightly with the lead screw 110, and the handwheel 105 has anti-slip textures for easy operation. The motor 106 has a large power to meet the mixing requirements of different intensities. In the mixing tank mechanism 2, the square groove 201 has a buffer pad inside to reduce the impact of vibration on the base 101. The magnetic disk 203 and the plum blossom-shaped magnetic pieces 202 have strong magnetism to ensure that the tank body 207 is fixed and stable. The vibration motor 205 is evenly distributed and can effectively remove air bubbles. The tank body 207 is made of corrosion-resistant material, and the wiring trough 208 has a protective cover to prevent damage to the power cord. During operation, first put the material into the tank 207, place the tank 207 on the square groove 201, so that the plum blossom-shaped magnet 202 is attracted to the magnet disk 203, turn the handwheel 105 to lower the T-shaped support plate 107, cover the tank 207 with the lid 108, and start the motor 106 and the vibration motor 205 to stir and exhaust the air.

[0019] Example 3: A desert sand composite cement mortar mixer. The base 101 of the mixing drive mechanism 1 has an anti-slip pad to prevent the equipment from moving. The upright frame 103 and the crossbeam 104 are hollow structures to reduce weight while ensuring strength. The guide rod 102 is made of stainless steel for wear resistance. The through holes and nuts of the T-shaped support plate 107 have lubrication devices to reduce friction. The motor 106 has a cooling fan to prevent overheating. In the mixing tank mechanism 2, the square groove 201 has positioning protrusions on its edge to facilitate quick positioning of the tank 207. The plum blossom-shaped grooves of the magnet disc 203 and the plum blossom-shaped magnet pieces 202 have smooth surfaces to reduce wear during adsorption. The vibration motor 205 has an independent control switch to adjust the vibration intensity as needed. The tank 207 has an observation window for easy observation of the mixing process, and the cable tray 208 has a cable management device to keep the power cord neat. When in use, place the tank 207 on the square groove 201 along the positioning protrusion so that the plum blossom-shaped magnet 202 is attracted to the magnet disk 203. Turn the handwheel 105 to lower the T-shaped support plate 107 and cover the tank 207 with the lid 108. Observe the material condition through the observation window, start the motor 106 to stir, and adjust the intensity of the vibration motor 205 as needed to remove air bubbles.

[0020] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: The tank 207 is placed above the square groove 201 fixed to the front side of the upper surface of the base 101, so that the plum blossom-shaped magnet 202 fixed to the bottom surface of the support plate 204 at the bottom end of the tank 207 corresponds to the plum blossom-shaped groove on the upper surface of the magnet disk 203 fixed to the upper surface of the square groove 201. Because the plum blossom-shaped magnet 202 and the magnet disk 203 are magnetically attracted to each other, the position of the tank 207 in the axial and vertical directions is restricted, preventing rotation or displacement during subsequent stirring. Then, the stirring drive mechanism 1 is operated, rotating through to the top plate. The screw 110, with a handwheel 105 fixedly connected to its end, is rotatably connected to the middle section of the upper surface of the base plate fixed to the upper surface of the base 101. The bottom end of the guide rod 102 is fixed to the left and right sides of the upper surface of the base plate, and its top end is close to the crossbeam 104 fixed to the top of the upright 103. The T-shaped support plate 107 has through holes on its rear left and right sides for the guide rod 102 to pass through, and sliding bearings are installed in these through holes. A nut that matches the outer thread of the screw 110 is embedded and fixed in the middle section of the rear side. Therefore, when the screw 110 rotates, it will cause the T-shaped support plate 107 to move up and down around the outer ring of the guide rod 102, causing the top of the T-shaped support plate 107 to move. The motor 106, fixedly connected to the upper surface of the T-shaped support plate 107 via a bracket, and the tank cover 108, fixed to the bottom surface of the T-shaped support plate 107 and adapted to the upper port of the tank 207, descend together until the tank cover 108 covers the tank 207. Simultaneously, the output shaft of the motor 106, connected to the stirring paddle 109 via a coupling, extends into the tank 207 through a circular hole provided inside the tank cover 108 for its penetration and rotation. Then, the motor 106 is started, and its output shaft drives the stirring paddle 109 to rotate inside the tank 207, stirring the desert sand composite cement mortar within the tank 207. During the stirring process, the motor 106 located on the bottom surface of the tank 207 is activated. Four vibrating motors 205 are fixed in a ring array on the lower surface of a fixed circular trough 206. The vibration generated by the vibrating motors 205 is transmitted to the tank 207, and the air bubbles generated during the mixing process are discharged by vibration. The power cord of the vibrating motor 205 is led out from the wiring groove 208 provided on the rear side of the bottom of the tank 207 to provide the power cord to pass through and connect to an external power source. After the mixing is completed, the handwheel 105 is rotated in the opposite direction, so that the lead screw 110 rotates in the opposite direction, driving the T-shaped support plate 107 to rise, thereby causing the motor 106, the stirring paddle 109 and the tank cover 108 to rise and leave the tank 207. Finally, the mixed desert sand composite cement mortar is taken out from the tank 207.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
