Description

Technical Field

[0001] The present application relates to the technical field of mortar mixing, and specifically discloses an admixture feeding device for a premixed mortar mixing station. Background Art

[0002] Premixed mortar refers to a granular or powdery material that is physically mixed in a certain proportion of dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bagged or bulk form and can be used directly after adding water and mixing.

[0003] Commonly used admixtures include cellulose ether, redispersible latex powder, thixotropic lubricants, defoamers, air entraining agents, coagulants, hydrophobic agents, etc. During the mixing process of premixed mortar, it is usually necessary to quantitatively configure a variety of admixtures. In traditional mixing stations, various admixtures are usually weighed in a measuring bucket, and then the various additives are mixed or introduced separately into the mixing station to be mixed with cement, etc. The weighing of various admixtures separately is not only cumbersome and complicated, but also because some admixtures have a certain viscosity and are easy to adhere to the inner wall of the measuring bucket, affecting the addition accuracy. This affects the accuracy of the raw material ratio of the premixed mortar as a whole. Therefore, in view of this, the inventor provides a premixed mortar mixing station admixture feeding device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in traditional mixing stations that each admixture needs to be weighed separately, resulting in a cumbersome and complicated admixture adding process.

[0005] In order to achieve the above-mentioned purpose, the basic solution of the utility model provides an admixture feeding device for a ready-mixed mortar mixing station, comprising:

[0006] Mounting rack;

[0007] A feed pipe is horizontally arranged on the mounting frame and the top of the feed pipe is connected to a plurality of feed branches. A rotating roller is rotatably sealed in the feed pipe, and the rotating roller is provided with a material trough located below each feed branch;

[0008] A feed cylinder is arranged parallel to the lower portion of the feed pipe and is connected to the bottom of the feed pipe. One end of the feed cylinder is connected to the side wall of the mixing station. The other end of the feed cylinder is slidably and sealedly connected to a guide rod. One end of the guide rod extends into the feed cylinder and is provided with a piston slidably and sealedly connected to the inner wall of the feed cylinder.

[0009] The driving mechanism drives the rotating roller to rotate and drives the guide rod to slide back and forth.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the present invention sets a feed pipe and a feed barrel so that different types of admixtures enter the feed pipe from each feed branch pipe respectively, and are stored in the material trough according to the corresponding volume, and uses a driving mechanism to drive the rotating roller to rotate, so that the direction of the material trough is reversed, and the admixtures accumulated in the material trough are circulated into the feed barrel respectively, and then the driving mechanism is used to drive the guide rod to slide, so that the piston slides in the feed barrel, and then the admixtures in the feed barrel are all passed into the mixing station for mixing with cement, etc. The present invention presets the volume size of each material trough so that different types of admixtures can be passed into the mixing station according to the corresponding proportion, and there is no need to weigh each admixture in turn, which simplifies the process of adding admixtures in the mixing station and improves the efficiency of adding admixtures, that is, improves the processing efficiency of the mixing station, and solves the problem that in traditional mixing stations, each admixture needs to be weighed separately, resulting in a cumbersome and complicated admixture addition process.

[0012] Furthermore, the driving mechanism includes a cylinder, a connecting rod attached to the cylinder's piston rod, and a rotating shaft attached to one end of the rotating roller. The rotating shaft has an arcuate groove on its sidewall, and the connecting rod has a slider slidably connected to the arcuate groove. The reciprocating motion of the cylinder's piston rod drives the guide rod to reciprocate. Simultaneously, the reciprocating motion of the guide rod drives the rotating shaft to rotate by engaging the slider with the arcuate groove, thereby driving the rotating roller to rotate.

[0013] Furthermore, the length of the arcuate groove along the axis of the rotating shaft is equal to the stroke of the piston, and the arcuate groove rotates 180 degrees along the surface of the rotating shaft. As a result, during one cycle of the cylinder's movement, the rotating roller completes a 180-degree rotation and resets, allowing the additive stored in the trough to flow into the feed barrel and reset.

[0014] Furthermore, two arcuate grooves are symmetrically arranged on either side of the rotating shaft, and two connecting rods are symmetrically arranged on either side of the piston rod of the cylinder. The ends of each connecting rod are provided with a slider that slides within the arcuate groove. This arrangement makes the slider and the arcuate groove more symmetrical, resulting in a more uniform force applied to the rotating shaft, thereby improving the control effect of the rotating shaft.

[0015] Furthermore, a mounting ring for mounting the connecting rod is provided on the piston rod of the cylinder, and the mounting ring facilitates symmetrical mounting of the two connecting rods.

[0016] Furthermore, a fixing sleeve is provided on the mounting frame, and one end of the rotating shaft is rotatably connected in the fixing sleeve. The fixing sleeve can limit and guide the rotation of the rotating shaft, thereby preventing the rotating shaft from positionally deviating during the rotation process.

[0017] Furthermore, the volume of the material tank is set in proportion to the ratio of each admixture, so that each admixture enters the material tank according to the corresponding ratio, ensuring the accuracy of the ratio of each admixture in the mortar. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0022] The figure marks in the drawings of the specification include: mounting frame 1, feed barrel 2, feed pipe 3, feed branch pipe 4, cylinder 5, gantry 6, piston rod 7, rotating shaft 8, mounting ring 9, connecting rod 10, slider 11, rotating roller 12, piston 13, through hole 14, and material trough 15.

[0023] A premixed mortar mixing station admixture feeding device, for example Figure 1 As shown: It includes a mounting frame 1, a feed pipe 3 provided on the mounting frame 1, a feed cylinder 2 and a driving mechanism, which are specifically as follows:

[0024] Mounting frame 1: The mounting frame 1 is arranged on the side wall of the mixing station, fixed relative to the mixing station by bolts or welding, and serves as the basic frame for installing the feed pipe 3, feed barrel 2 and drive mechanism.

[0025] Feed pipe 3: The feed pipe 3 is horizontally arranged on the mounting frame 1 and the top of the feed pipe 3 is connected to a plurality of feed branches 4. A rotating roller 12 is rotatably sealed in the feed pipe 3. The rotating roller 12 is provided with a material trough 15 located below each feed branch 4. The volume of the material trough 15 is set in proportion to the ratio of each additive.

[0026] Feed barrel 2: The feed barrel 2 is arranged parallel to the bottom of the feed pipe 3 and is connected to the bottom of the feed pipe 3. The feed pipe 3 and the side wall of the feed barrel 2 are provided with a through hole 14 that is connected to each other. One end of the feed barrel 2 is connected to the side wall of the mixing station, and the other end of the feed barrel 2 is slidingly and sealedly connected to a guide rod. One end of the guide rod extends into the feed barrel 2 and is provided with a piston 13 that is slidingly and sealingly connected to the inner wall of the feed barrel 2.

[0027] Driving mechanism: The driving mechanism drives the rotating roller 12 to rotate and drives the guide rod to slide back and forth. Specifically, the driving mechanism includes a cylinder 5, a mounting ring 9 provided on the piston rod 7 of the cylinder 5, connecting rods 10 symmetrically provided on both sides of the mounting ring 9 and a rotating shaft 8 provided at one end of the rotating roller 12. The side walls of the rotating shaft 8 are symmetrically provided with arc grooves, and the connecting rods 10 are provided with sliders 11 slidably connected to the arc grooves. The length of the arc groove along the axial direction of the rotating shaft 8 is the same as the stroke of the piston 13. The angle of rotation of the arc groove along the surface of the rotating shaft 8 is 180°. A gantry 6 is provided on the mounting frame 1, and a fixed sleeve is installed on the gantry 6. A section of the rotating shaft 8 is connected in the fixed sleeve.

[0028] During the implementation of this embodiment, various types of additives enter the feed pipe 3 from the feed branches 4 and are stored in the trough 15 according to the corresponding volume. At this time, the piston 13 should be located on the side of the feed barrel 2 close to the mixing station, that is, Figure 2 The cylinder 5 is started, and the guide rod drives the piston 13 to move right. At the same time, the slider 11 slides in the arc groove, so that the rotating shaft 8 drives the rotating roller 12 to turn over. When the piston 13 is completely moved to the rightmost end, the rotating roller 12 rotates 180°. In the stroke of the piston 13, sufficient margin should be left to prevent the admixture in the material trough 15 from flowing out when the piston 13 slides to the through hole 14 at the end position, that is, to prevent the admixture from flowing into the right end of the piston 13. Then the cylinder 5 stops. After a period of time, the cylinder 5 is started in the reverse direction, and the piston 13 moves left, so that the admixture in the feed barrel 2 is all passed into the mixing station to be mixed with cement, etc., and the rotating roller 12 is reset under the action of the slider 11 and the arc groove.

[0029] The utility model presets the volume size of each material holding trough 15 so that different types of admixtures can be introduced into the mixing station according to the corresponding proportions, and there is no need to weigh each admixture in turn, which simplifies the process of adding admixtures in the mixing station and improves the efficiency of adding admixtures, that is, improves the processing efficiency of the mixing station, and solves the problem of needing to weigh each admixture separately in the traditional mixing station, which makes the admixture addition process cumbersome and complicated.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
