Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a concrete batching machine for producing environmentally friendly concrete. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and additives added in a certain proportion, which are uniformly mixed, compacted, and cured and hardened. At present, when preparing environmentally friendly concrete, it is necessary to quantitatively batch the raw materials. At the same time, due to the large production volume and heavy quality of the ingredients, it is necessary to facilitate the unloading and transportation after the rapid batching is completed. At the same time, some raw materials will contain large debris during the batching, and they need to be properly screened during the batching to meet the needs of batching processing.

[0003] The existing Chinese patent CN220280070U is a concrete batching machine for environmentally friendly concrete production. When solving the above problems, the aggregates are simply piled up on the screening net and screened by the gravity of the aggregates. This screening method is inefficient and avoids the accumulation of filtered aggregates on the screening net, which affects the subsequent screening operation. As a result, the staff needs to frequently disassemble the screening net to clean out the internal aggregates, which greatly increases the workload of the staff. Utility Model Content

[0029] Working principle: The utility model is a concrete batching machine for environmentally friendly concrete production. During use, aggregate is put into the top of the movable frame 3, the coarser aggregate is filtered by the filter 4, and the finer aggregate falls into the bottom of the inner cavity of the hopper 1. At this time, the conical block 19 blocks the bottom of the hopper 1. When the aggregate at the bottom of the inner cavity of the hopper 1 needs to be discharged, the motor 29 is started by an external power supply, and the motor 29 drives the first worm 18 and the second worm 27 through the rotating rod 28. The first worm 18 drives the first worm wheel 17 to rotate, and the second worm 27 drives the second worm wheel 26 to rotate. The first worm wheel 17 drives the square tube 13 to rotate in the inner cavity of the first bearing 12, and the square tube 13 drives the square rod 14 to rotate. The square rod 14 drives the scraper 15 to rotate, and the scraper 15 scrapes the coarser aggregate attached to the top of the filter 4, thereby stirring the aggregate. To speed up the filtering of aggregates, the second worm gear 26 drives the threaded rod 24 to rotate in the inner cavity of the second bearing 25 and the threaded tube 23. The threaded tube 23 moves downward relative to the threaded rod 24 under the action of the thread. The threaded tube 23 drives the conical block 19 to move downward through the cross bar 22, thereby opening the bottom opening of the hopper 1. The aggregates at the bottom of the inner cavity of the hopper 1 are discharged under the action of gravity. Compared with the prior art, the device works through the motor 29, which can drive the scraper 15 to rotate and the conical block 19 to move downward. When the scraper 15 rotates, it scrapes the coarser aggregates attached to the top of the filter screen 4, thereby stirring the aggregates, which can speed up the filtering of aggregates. There is no need to frequently disassemble the movable frame 3 to clean the internal aggregates, which reduces the labor of the staff. When the conical block 19 moves downward, the material discharge operation is realized, which kills two birds with one stone and is more convenient to use.

[0030] When it is necessary to disassemble the movable frame 3 to clean the internal aggregate, loosen the locking screw 16, unlock the fixation of the square rod 14, and then move the square rod 14 upward. The square rod 14 drives the scraper 15 to move upward away from the filter screen 4. At this time, the scraper 15 moves to the inner cavity away from the movable frame 3, and then unscrew the fixing screw 9, unlock the fixation of the movable frame 3, and then lift the movable frame 3 upward by the two handles 6, so that the movable frame 3 moves away from the hopper 1, and then move the movable frame 3 to the side to complete the disassembly of the movable frame 3, so as to clean the aggregate inside the movable frame 3.
