[0002] Concrete slump refers to the plasticizing performance and pumpability of concrete, and the slump is a quantitative index for measuring the degree (plasticizing performance and pumpability) of concrete, and is used to determine whether the construction can proceed normally.
[0003] The existing concrete slump detection device usually comprises a vibration detection table and a slump bucket arranged on the detection table. During detection, the concrete is loaded into the slump bucket until the top of the concrete is flush with the top of the slump bucket, the detection table is vibrated, and the height difference of the concrete in the slump bucket before and after vibration is measured. When loading the concrete into the slump bucket, a hopper is usually arranged on the top of the slump bucket, and the hopper is used to guide 3 / 5 of the detection amount of concrete into the slump bucket to avoid the concrete spilling on the detection table and affecting the detection. Then, the hopper is pulled out, and the remaining 2 / 5 of the detection amount of concrete is poured into the slump bucket. However, due to the lack of guidance or limiting effect of the hopper, the concrete is easy to spill or overflow onto the detection table. If the hopper is used to pour the entire detection amount of concrete into the slump bucket, the concrete at the bottom of the hopper is also easy to overflow onto the detection table when the hopper is pulled out. In order to solve the above problems, some slump buckets are provided with a circle of overflow grooves around the slump bucket to receive the overflowing concrete, but this structure is not conducive to the cleaning of the slump bucket.
