Description

Technical Field

[0001] The utility model belongs to the technical field of concrete mixing, and in particular relates to a raw material bin anti-blocking structure for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials that are made by bonding aggregates into a whole with cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion and mixed together. It is also called ordinary concrete and is widely used in civil engineering.

[0003] In the related art, a raw material bin anti-blocking structure for concrete production with patent number CN217375736U includes a cylinder, a control panel is provided at the front end of the cylinder, and a discharge hopper is fixedly connected to the lower end of the cylinder. The raw material bin anti-blocking structure for concrete production puts the raw materials used for concrete production into the cylinder through the feed hopper, and can drive multiple groups of separation rods to rotate through the rotation of the motor to break up the block raw materials entering the cylinder. At the same time, once the discharge hopper of the cylinder is blocked, the hammer head can be controlled to extend and retract through the electric telescopic rod to directly break the raw materials blocked in the discharge hopper and clear the discharge hopper. At the same time, during the use of the raw material bin, the buffer mechanism can be used to buffer and damp the raw material bin when adding materials, and the spring inside the buffer mechanism can be used to dampen the shock, thereby increasing the service life of the raw material bin and greatly improving its practicality.

[0004] In the above device, the blocked concrete at the discharge port is hammered open by a buffer mechanism, which will cause the solidified concrete material to remain solidified, but the volume will be reduced. When using this kind of concrete, it will affect the molding effect and quality of the building.

[0005] In the prior art, after concrete materials are placed in a raw material bin, they are mixed and combined with water to make concrete for use. Since the concrete raw materials contain a large amount of sand and gravel and some materials with a density greater than water, when these materials enter the raw material bin, they will accumulate at the bottom of the raw material bin and are not easy to break up and then mix with water. After the concrete materials are mixed, when discharging, those materials may gather into lumps, causing the discharge port of the raw material bin to be blocked, affecting the preparation progress of the concrete.

[0026] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0027] refer to Figure 1-7A raw material silo anti-blocking structure for concrete production includes a symmetrically arranged support plate 1, a mixing frame 2 is fixedly arranged on the upper end of the support plate 1, a mixing shaft 22 and a spiral feeding shaft 23 are installed in the mixing frame 2, the mixing shaft 22 is located above the spiral feeding shaft 23, and is rotatably arranged inside the mixing frame 2, the spiral feeding shaft 23 is close to the inner bottom surface of the mixing frame 2, and the mixing shaft 22 and the spiral feeding shaft 23 are both at a certain distance from the inner wall of the mixing frame 2, a discharge port 212 is opened at the lower position of one side surface of the mixing frame 2, a discharge frame 24 is fixedly arranged at the position of the discharge port 212, and the opening of the discharge frame 24 faces downward.

[0028] refer to Figure 2-5 The two ends of the spiral feeding shaft 23 are respectively fixedly installed with a connecting shaft 36 and a baffle 231. The connecting shaft 36 is used to drive the rotation of the spiral feeding shaft 23 on the one hand, and can also be used to promote the movement of the spiral feeding shaft 23 on the other hand. After it moves, it will increase the function of auxiliary discharging on the basic function of stirring. One end of the spiral feeding shaft 23 is rotatably set on the surface of the baffle 231, and the baffle 231 is slidably set at the discharge port 212, and can also slide in the discharge frame 24. A plurality of sliding columns 232 are fixedly set on the outer side of the baffle 231. The sliding columns 232 penetrate the side of the discharge frame 24 and slide together. The sliding columns 232 are used to ensure the stability of the spiral feeding shaft 23 when it moves.

[0029] Furthermore, the rotation diameter of the stirring shaft 22 is larger than the rotation diameter of the spiral feed shaft 23. Since the density of concrete aggregate is greater than that of water, most of the aggregate will sink to the bottom of the mixing frame 2 after entering the mixing frame 2. At this time, the stirring shaft 22 can fully mix and fuse most of the concrete raw materials and water in the middle layer of the mixing frame 2. At the same time, the spiral feed shaft 23 can stir at the bottom of the mixing frame 2. Through the coordinated rotation of the stirring shaft 22 and the spiral feed shaft 23, the concrete raw materials inside the mixing frame 2 can be fully combined with water, so that gravel, sand, cement and water will not solidify, causing blockage during discharging.

[0030] refer to Figure 2-3A support platform 31 is provided next to the stirring frame 2, and a telescopic cylinder 32 is fixedly provided on the upper surface of the support platform 31, and a support frame 33 is fixedly provided at a position on the surface of the support platform 31 away from the telescopic cylinder 32, and a motor 2 331 is fixedly provided in the support frame 33, and the output shaft of the motor 2 331 is fixedly connected to one end of the stirring shaft 22, and a gear 1 332 is fixedly provided on the surface of the output shaft of the motor 2 331, and a toothed belt 34 is meshed on the surface of the gear 1 332, and a plurality of clips are fixedly provided on the surface of the connecting shaft 36 in an annular shape, and a gear 2 35 is provided on the surface of the connecting shaft 36, and the inner ring of the gear 2 35 is clipped with the clip, and the gear 2 35 can slide on the surface of the connecting shaft 36, and the toothed belt 34 is meshed with the gear 2 35, and the motor 2 331 drives the gear 1 332 to rotate, and then the toothed belt 34 drives the gear 2 35 to rotate, so that the stirring shaft 22 and the spiral feeding shaft 23 rotate and stir in the stirring frame 2.

[0031] refer to Figure 2-4 A stepped annular groove 211 is provided on one side of the mixing frame 2 relative to the position of the gear 2 35, and a stepped connecting ring 351 is rotatably provided in the stepped annular groove 211. The stepped connecting ring 351 is fixedly provided on the side of the gear 2 35. By rotating the stepped connecting ring 351 in the stepped annular groove 211, it can be ensured that the gear 2 35 can maintain its position unchanged when the connecting shaft 36 is displaced, and then the connecting shaft 36 can be driven to rotate stably.

[0032] refer to Figure 2-3 The outer end of the piston rod of the telescopic cylinder 32 is fixedly provided with a support tube 321, and one end of the connecting shaft 36 is rotatably set in the support tube 321. The telescopic cylinder 32 pushes the connecting shaft 36, thereby driving the displacement of the spiral feeding shaft 23, and then the spiral feeding shaft 23 will drive the baffle 231 to slide in the discharge frame 24. During the movement, the stirring is stopped. With the movement of the baffle 231, the stirred concrete will be discharged from the position of the discharge port 212. At this time, the motor 2 331 is started, and then the stirring shaft 22 and the spiral feeding shaft 23 will rotate at the same time. At this time, a part of the spiral feeding shaft 23 is already in the discharge frame 24. Its rotation can drive the concrete inside the mixing frame 2 to be discharged quickly, and at the same time, it can also ensure that no blockage occurs during discharge.

[0035] Furthermore, before cleaning, the concrete inside the mixing frame 2 has been discharged, and most of the remaining concrete is concrete residue attached to the inner wall of the mixing frame 2. At this time, the motor 253 drives the screw 251 to rotate, and then the slider 252 drives the U-shaped scraper 25 to clean the inner wall of the mixing frame 2, wherein the U-shaped scraper 25 can effectively separate the concrete attached to the inner walls and inner bottom surfaces on both sides of the mixing frame 2, so that it will not accumulate for a long time and cause blockage during the next mixing time. At the same time, a water pipe can also be used to rinse the inner wall of the mixing frame 2, which can speed up the cleaning time and improve the cleaning effect.
