Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a concrete batching mixer. Background Art

[0002] Concrete is a cement concrete obtained by mixing cement as the gelling material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion.

[0003] Most existing concrete mixing devices directly add concrete raw materials into the mixing device according to a certain ratio and use a stirring roller to mix the various raw materials. However, when the various raw materials accumulate in the mixing device, it will make it difficult for the stirring roller to quickly and evenly mix the materials, which can easily cause uneven mixing and lead to reduced concrete quality. To address the above shortcomings: To this end, we propose a concrete batching mixer. Utility Model Content

[0011] Preferably, the driving component includes a mounting plate, a driven pulley, a second motor fixedly mounted on the upper surface of the mounting plate, and a driving pulley fixedly mounted on the output end of the second motor.

[0012] Preferably, both ends of the driven pulley are fixedly connected to opposite surfaces of the cement conveying auger and the aggregate conveying auger respectively.

[0013] Preferably, the driving pulley and the driven pulley are connected via a belt transmission, and a groove for the belt to pass through is provided on the surface of the mounting plate.

[0014] Preferably, the lower surface of the mounting plate is fixedly connected to the surfaces of the cement conveying cylinder and the aggregate conveying cylinder respectively.

[0015] Preferably, one end of the cement conveying auger extends to the interior of the cement storage silo.

[0016] Preferably, one end of the aggregate conveying auger extends to the interior of the aggregate storage bin.

[0017] Preferably, leakage holes are provided on the surfaces of the cement conveying cylinder and the aggregate conveying cylinder, and the inner diameters of the cement conveying cylinder and the aggregate conveying cylinder need to be designed in proportion according to the requirements of concrete.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By setting up the batching structure and the mixing structure, cement and aggregate are placed in the cement storage silo and the aggregate storage silo respectively.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-4 The utility model provides a technical solution: a concrete batching mixer, including: a batching structure and a mixing structure.

[0029] See Figure 1 The batching structure includes a cement storage bin 1, an aggregate storage bin 2, and a material conveying assembly respectively arranged on opposite sides of the cement storage bin 1 and the aggregate storage bin 2. The material conveying assembly includes a first material feeding component, a second conveying component, and a driving component that can drive the first conveying component and the second conveying component to work.

[0030] See Figure 2 The first conveying component includes a cement conveying cylinder 6 fixedly installed at the left end of the cement storage bin 1, and a cement conveying auger 7 rotatably installed on the inner wall of the cement conveying cylinder 6, one end of the cement conveying auger 7 extends to the interior of the cement storage bin 1, and the second conveying component includes an aggregate conveying cylinder 8 fixedly installed at the right end of the aggregate storage bin 2, and an aggregate conveying auger 9 rotatably installed on the inner wall of the aggregate conveying cylinder 8, one end of the aggregate conveying auger 9 extends to the interior of the aggregate storage bin 2.

[0031] When the cement conveying auger 7 and the aggregate conveying auger 9 rotate, the cement in the cement storage bin 1 and the aggregate in the aggregate storage bin 2 can be driven to be discharged along the cement conveying cylinder 6 and the aggregate conveying cylinder 8 respectively. The rotating cement conveying auger 7 and the aggregate conveying auger 9 can prevent the cement and aggregate from getting stuck in the cement storage bin 1 and the aggregate storage bin 2.

[0032] The driving component includes a mounting plate 10, a driven pulley 11, a second motor 12 fixedly mounted on the upper surface of the mounting plate 10, and a driving pulley 13 fixedly mounted on the output end of the second motor 12. The lower surface of the mounting plate 10 is fixedly connected to the surfaces of the cement conveying cylinder 6 and the aggregate conveying cylinder 8, respectively.

[0033] The two ends of the driven pulley 11 are fixedly connected to the opposite surfaces of the cement conveying auger 7 and the aggregate conveying auger 9 respectively. The driving pulley 13 and the driven pulley 11 are connected by belt transmission, and the surface of the mounting plate 10 is provided with a groove for the belt to pass through. Driving the second motor 12 can drive the driving pulley 13 to rotate, and the driven pulley 11 can be driven to rotate by the belt transmission. When the driven pulley 11 rotates, the cement conveying auger 7 and the aggregate conveying auger 9 can be driven to rotate synchronously.

[0034] See Figure 3 The mixing structure includes a mixing drum 3 and a mixing blade 4 rotatably installed on the inner wall of the mixing drum 3, and a first motor 5 that can drive the mixing blade 4 to rotate is fixedly installed on the right side of the mixing drum 3. When the cement and aggregate are discharged along the aggregate conveying drum 8 and the cement conveying drum 6 respectively, they will fall into the mixing drum 3. Then, driving the first motor 5 can drive the mixing blade 4 to rotate, and the rotating mixing blade 4 can be used to mix the cement and aggregate.

[0035] Cement and aggregate are placed in the cement storage bin 1 and the aggregate storage bin 2 respectively, and then the material conveying assembly can be used to convey the cement and aggregate along the cement conveying cylinder 6 and the aggregate conveying cylinder 8 to the mixing drum 3 respectively. During the conveying, the mixing structure can mix the cement and aggregate that have been conveyed to the mixing drum 3, and convey the cement and aggregate to the mixing drum 3 in multiple times, and cooperate with the continuously rotating stirring blade 4, so as to avoid the defect that a large amount of unmixed aggregate and cement accumulate in the mixing drum 3 and cannot be quickly and evenly stirred.

[0036] See Figure 4 The surfaces of the cement conveying cylinder 6 and the aggregate conveying cylinder 8 are both provided with leakage holes 14. The leakage holes 14 can discharge part of the cement and aggregate in advance, so that they fall into other positions in the mixing drum 3, to avoid the accumulation of materials after falling. The inner diameters of the cement conveying cylinder 6 and the aggregate conveying cylinder 8 need to be designed in proportion according to the requirements of concrete. The inner diameters of the cement conveying cylinder 6 and the aggregate conveying cylinder 8 are designed in proportion according to the requirements of concrete, so that cement and aggregate can be delivered to the mixing drum 3 in proportion, avoiding the large difference in the cement and aggregate delivery ratio affecting the quality of concrete after production.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
