Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and more specifically to a concrete vibratory mixer. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, if necessary, admixtures and additives in a certain proportion, uniformly mixing, and compacting. Vibratory mixers, driven by a vibrating motor, vibrate the mixing shaft at a high frequency of 1500-1600 times per minute. The mixing shaft also drives the mixing arms and mixing blades to vibrate together. This combination of low-speed mixing and high-efficiency vibration achieves an effective combination of macroscopic convection and microscopic diffusion through vibration mixing, which can truly achieve microscopic uniformity of concrete and is widely popular.

[0003] Insufficiency of existing technology: The movement trajectory of the mixing paddle in existing vibratory mixers is simple. It is a single circular motion and rotates in one direction during the mixing process, which affects the mixing efficiency and quality. At the same time, the concrete tends to stick to the inner wall of the mixing drum during the mixing process, which affects the uniformity of concrete mixing. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concrete vibration mixer to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete vibratory mixer, comprising a main body, and further comprising: a mixing mechanism, a cleaning mechanism, and a driving mechanism. The top end of the main body is fixedly connected to the bottom end of the driving mechanism, the bottom end of the mixing mechanism is movably connected to the top end of the main body, and the top end of the cleaning mechanism is fixedly connected to the bottom end of the mixing mechanism. The main body includes a mixing drum, the bottom end of which has a placement groove. The mixing mechanism includes a support plate, the side of which is movably connected to the side of the placement groove. The top end of the support plate is movably fitted with two driven gears via pins. A vibratory motor is fixedly connected to the top end of each driven gear. The output shaft of the vibratory motor passes through the bottom end of the support plate and is fixedly connected to a mixing shaft. A mixing paddle is fixedly connected to the side of the mixing shaft. A discharge pipe is fixedly connected to the bottom end of the mixing drum, and support legs are fixedly connected to the bottom end of the mixing drum.

[0006] Furthermore, the drive mechanism includes a mounting frame, the bottom end of which is fixedly connected to the top end of the mixing tank, a drive motor fixedly connected to the side of the mounting frame, a drive gear fixedly connected to the output shaft of the drive motor, and a second transmission gear movably sleeved on the top end of the support plate via a pin. The side of the second transmission gear meshes with the side of the drive gear and the side of the driven gear.

[0007] Furthermore, an internal gear is fixedly connected to the side of the placement slot, and a first transmission gear is movably sleeved on the top of the support plate via a pin. The side of the first transmission gear meshes with the side of the internal gear, and the side of the first transmission gear meshes with the side of the second transmission gear.

[0008] Furthermore, the cleaning mechanism includes a mounting shaft, the top end of which is fixedly connected to the bottom end of a support plate, a connecting rod fixedly connected to the side of the mounting shaft, a mounting plate fixedly connected to the side of the connecting rod, a mounting plate movably connected to the side of the mounting plate, and the side of the mounting plate movably connected to the inner side wall of the mixing tank.

[0009] Furthermore, the side of the mounting plate has an arc-shaped structure, and the mounting plate is at an 80-degree angle to the horizontal plane.

[0010] Furthermore, the mounting plate has a mounting groove on its side, and a pressure spring is fixedly connected to the side of the mounting groove. The side of the pressure spring is fixedly connected to the side of the scraper.

[0011] Furthermore, the stirring shafts on both sides are symmetrically distributed along the circle of the stirring tank, the mounting plates on both sides are symmetrically distributed along the circle of the stirring tank, and the cross-sectional angle between the stirring mechanism and the cleaning mechanism is ninety degrees.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a drive mechanism to slowly rotate the two side support plates around the center of the mixing tank, causing the two side mixing shafts to rotate in a horizontal plane. This mixes the concrete raw materials inside the mixing tank. The two side mixing shafts rotate independently, causing the mixing paddle to rotate along the mixing shaft. The direction of rotation of the mixing shaft is opposite to that of the support plate. This causes the eddy current generated by the rotating mixing paddle along the mixing shaft to collide with the eddy current generated by the two side mixing shafts around the center of the mixing tank, improving the mixing efficiency. At the same time, the vibration motor drives the mixing shaft to vibrate at high frequency to expel air bubbles mixed in the concrete, making the raw materials compact and further improving the mixing efficiency.

[0014] 2. This utility model uses an installation plate that rotates along the center of the mixing tank with the support plate. A pressure spring pushes the scraper to keep it in close contact with the inner side wall of the mixing tank, so that the scraper scrapes off the raw materials adhering to the inner side wall of the mixing tank. After the mixing is completed, the control valve on the discharge pipe is opened to discharge the raw materials through the discharge pipe, which helps to ensure that the raw materials are mixed evenly.

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The concrete vibrating mixer involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 5This utility model provides a concrete vibratory mixer, including a main body 1, and further including: a mixing mechanism 2, a cleaning mechanism 3, and a driving mechanism 4. The top end of the main body 1 is fixedly connected to the bottom end of the driving mechanism 4, the bottom end of the mixing mechanism 2 is movably connected to the top end of the main body 1, and the top end of the cleaning mechanism 3 is fixedly connected to the bottom end of the mixing mechanism 2. The main body 1 includes a mixing tank 101, and a placement groove 104 is provided at the bottom end of the mixing tank 101. The mixing mechanism 2 includes a support plate 202, the side of the support plate 202 is movably connected to the side of the placement groove 104, and the top end of the support plate 202 is movably sleeved with two driven gears 204 by pins. A vibration motor 203 is fixedly connected to the end of the mixing tank 101. The output shaft of the vibration motor 203 passes through the bottom end of the support plate 202 and is fixedly connected to the stirring shaft 201. A stirring paddle 205 is fixedly connected to the side of the stirring shaft 201. A discharge pipe 102 is fixedly connected to the bottom end of the mixing tank 101 and a support leg 103 is fixedly connected to the bottom end of the mixing tank 101. When the equipment is running, the drive mechanism 4 drives the support plate 202 to rotate slowly around the center of the mixing tank 101, so that the two stirring shafts 201 on both sides rotate in the horizontal plane to stir the concrete raw materials inside the mixing tank 101. At the same time, the vibration motor 203 drives the stirring shaft 201 to vibrate at high frequency to discharge the air bubbles mixed in the concrete, so that the raw materials are mixed and compacted.

[0023] The drive mechanism 4 includes a mounting frame 401, the bottom of which is fixedly connected to the top of the mixing tank 101. A drive motor 402 is fixedly connected to the side of the mounting frame 401. A drive gear 405 is fixedly connected to the output shaft of the drive motor 402. A second transmission gear 406 is movably sleeved on the top of the support plate 202 via a pin. The side of the second transmission gear 406 meshes with the side of the drive gear 405 and with the side of the driven gear 204. The drive motor 402 drives the drive gear 405 to rotate. Through the meshing of the drive gear 405 and the second transmission gear 406, and the meshing of the second transmission gear 406 and the driven gear 204, the two mixing shafts 201 on both sides rotate, so that the mixing paddle 205 mixes the concrete raw materials.

[0024] The placement groove 104 is fixedly connected to an internal gear 403, and the top of the support plate 202 is movably sleeved with a first transmission gear 404 through a pin. The side of the first transmission gear 404 meshes with the side of the internal gear 403, and the side of the first transmission gear 404 meshes with the side of the second transmission gear 406. The driven gear 204 rotates, and through the meshing of the driven gear 204 with the first transmission gear 404, the first transmission gear 404 and the internal gear 403 mesh with each other, driving the support plate 202 to rotate in the placement groove 104. The rotation direction of the stirring shaft 201 is opposite to the rotation direction of the support plate 202, so that the stirring paddle 205 rotates along the stirring shaft 201 to generate vortices, which collide with the vortices generated by the two stirring shafts 201 along the center of the mixing tank 101, thereby improving the mixing efficiency.

[0025] The cleaning mechanism 3 includes a mounting shaft 301, the top end of which is fixedly connected to the bottom end of the support plate 202. A connecting rod 303 is fixedly connected to the side of the mounting shaft 301, and a mounting plate 302 is fixedly connected to the side of the connecting rod 303. The side of the mounting plate 302 is movably connected to the inner wall of the side of the mixing tank 101. As the support plate 202 rotates, the mounting shaft 301 rotates, causing the mounting plates 302 on both sides to rotate, thereby causing the pressure spring 305 to scrape away the debris from the inner wall of the side of the mixing tank 101.

[0026] The mounting plate 302 has an arc-shaped side and is at an 80-degree angle to the horizontal plane. The scraper 304 rotates counterclockwise with the support plate 202 to prevent concrete from splashing inside the mixing tank 101.

[0027] The mounting plate 302 has a mounting groove 306 on its side, and a pressure spring 305 is fixedly connected to the side of the mounting groove 306. The side of the pressure spring 305 is fixedly connected to the side of the scraper 304. The pressure spring 305 pushes the scraper 304 so that the scraper 304 is always in close contact with the inner wall of the side of the mixing tank 101.

[0028] The two stirring shafts 201 are symmetrically distributed along the circle of the mixing tank 101, and the two mounting plates 302 are symmetrically distributed along the circle of the mixing tank 101. The cross-sectional angle between the stirring mechanism 2 and the cleaning mechanism 3 is 90 degrees. The line connecting the centers of the two mounting plates 302 is continuously perpendicular to the centers of the two stirring shafts 201 and is symmetrically distributed along the center of the mixing tank 101 to ensure that the equipment is subjected to uniform force.

[0029] The working principle of this utility model is as follows: Concrete raw materials are poured into the mixing drum 101. The equipment is started, and the drive motor 402 drives the active gear 405 to rotate. The active gear 405 meshes with the second transmission gear 406, and the second transmission gear 406 meshes with the driven gear 204, driving the two side mixing shafts 201 to rotate. This causes the mixing paddle 205 to rotate along the mixing shaft 201 to mix the concrete raw materials. Simultaneously, the vibration motor 203 drives the mixing shaft 201 to vibrate at high frequency, expelling air bubbles mixed in the concrete and making the raw materials compact. The driven gear 204 meshes with the first transmission gear 404, and the first transmission gear 404 meshes with the internal gear 403. The support plate 202 rotates in the placement trough 104, and the rotation direction of the stirring shaft 201 is opposite to that of the support plate 202. This causes the stirring paddle 205 to rotate along the stirring shaft 201, generating vortices that collide with the vortices generated by the stirring shafts 201 on both sides along the center of the mixing tank 101, thereby improving the mixing efficiency. The mounting plate 302 rotates along the center of the mixing tank 101 with the support plate 202, and pushes the scraper 304 through the pressure spring 305, so that the scraper 304 is always in close contact with the inner wall of the side of the mixing tank 101, so that the scraper 304 scrapes off the raw material attached to the inner wall of the side of the mixing tank 101. After the work is completed, the control valve on the discharge pipe 102 is opened to discharge the raw material through the discharge pipe 102.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
