Description

Technical Field

[0001] The invention relates to the technical field of concrete preparation, in particular to a proportioning wet mixing device for preparing concrete. Background Art

[0002] Concrete refers to an artificial stone made of cement as the main cementitious material, mixed with water, sand, gravel, and chemical admixtures and mineral admixtures when necessary, in appropriate proportions, and then mixed with a wet mixing device. After uniform mixing, compaction, and curing and hardening, the wet mixing device used for preparing concrete usually provides a rolling mechanism at the feeding position in order to improve the efficiency of the later mixing during use, and the large lumps in the raw materials are crushed by the rolling mechanism. However, since it takes a certain amount of time for the rolling mechanism to crush the large lumps, it is easy to affect the normal feeding of the raw materials. This not only easily leads to a slowdown in the feeding speed of the wet mixing device, but also easily leads to blockage due to too slow feeding. Summary of the invention

[0003] The disclosed embodiment relates to a proportioning wet mixing device for preparing concrete, which intercepts large lumps of raw materials through a filter plate and separates them from normal raw materials, allowing the large lumps to enter the crushing rollers from the other two channels for crushing before being discharged, while the normal raw materials will directly pass through the filter holes and enter the mixing body, thereby preventing the large lumps of raw materials from being discharged together with the normal raw materials and causing unnecessary trouble.

[0007] In at least some embodiments, a cylindrical connecting slide is fixedly installed at the center position of the bottom end of the cutting slide; the connecting slide is also slidably installed inside the mixing shaft; the bottom end of the connecting slide protrudes from the bottom end of the mixing shaft; and a sprocket D is fixedly installed at the bottom end of the mixing shaft.

[0008] In at least some embodiments, the sprocket D is connected to the sprocket C via a chain; a driven frame of a U-shaped structure is fixedly mounted on the bottom end of the connecting slide rod; and driven wheels are rotatably mounted on both ends of the bottom of the driven frame.

[0009] In at least some embodiments, the circumferential outer wall of the driven wheel is in close contact with the wavy surface on the top of the transmission member; a mixing rack is fixedly mounted on the circumferential outer wall of the mixing shaft; and four mixing racks and four cutting blades are arranged in a staggered manner.

[0010] In at least some embodiments, when the driving motor rotates the sprocket C, the sprocket C will rotate with the sprocket D and the mixing shaft under the action of the chain; when the mixing shaft rotates, it will rotate with the connecting seat and the driving gear ring.

[0011] In at least some embodiments, when the driving gear ring rotates, the driving gear ring will rotate with the transmission shaft and sprocket B due to the meshing with the transmission gear; when the sprocket B rotates, it will rotate with sprocket A and the corresponding crushing shaft due to the action of the chain.

[0012] In at least some embodiments, when one of the crushing shafts in each of the two groups rotates, the crushing shaft will drive the other crushing shaft to rotate relative to it under the action of the relative gear; when the mixing shaft rotates, it will also drive the cutting slide, the cutting blade and the mixing frame to rotate.

[0015] 1. The present invention divides the material discharge channel into three by means of a filter plate body. The arc-shaped structure of the filter plate body can intercept large agglomerates of raw materials and separate them from normal raw materials, so that large agglomerates enter the crushing rollers from the left and right channels for crushing before discharge, while normal raw materials directly pass through the filter holes and enter the mixing body, thereby avoiding the situation in which large agglomerates of raw materials are mixed with normal raw materials during discharge, resulting in slow discharge speed and material blockage due to excessive crushing speed.

[0016] 2. In the present invention, when the stirring shaft rotates with the mixing frame to wet mix the concrete, the cutting blade will also rotate and move downward intermittently with the cooperation of multiple structures, so that the cutting blade intermittently cuts a temporary crack in the concrete from top to bottom through the intermittent downward movement, so that the water injected from the top of the concrete can penetrate into the concrete below, thereby preventing the problem of poor concrete wet mixing effect due to the inability of the concrete below to evenly contact the water.
