Description

A knockout for cutting ring soil sample

Technical Field

The utility model relates to an earthwork is filled and is built compactness and detect technical field, especially relate to a knockout for cutting ring soil sample.

Background

Generally, the degree of compaction is one of the key indexes for detecting the quality of earth-rock dam construction, roadbed and pavement and foundation treatment backfill construction, and represents the density condition after on-site compaction, and the higher the degree of compaction is, the higher the density is. During the detection of the compaction degree of the backfill soil, a cutting ring is often needed to carry out on-site soil sampling, after the volume weight test of the soil sample is finished, the soil sample needs to be taken out of the cutting ring, the water content of the soil is tested by using the taken soil sample, and then the compaction degree of the backfill soil is calculated so as to evaluate the filling quality of the soil. In general, cohesive soil has strong adhesion, friction between soil and the inner wall of a ring cutter is large, tools such as a small iron hammer or a file are usually adopted to knock the wall of the ring cutter in the existing demolding mode, the soil is separated from the ring cutter by vibration force, not only is effort consumed, but also an experimenter is easily cut by the opening of the ring cutter or fingers are easily injured by the hammer, and meanwhile, the ring cutter is deformed or even damaged by too much knocking of the iron hammer on the ring cutter, so that the accuracy of experimental data is seriously influenced.

SUMMERY OF THE UTILITY MODEL

In order to realize the purpose, the utility model adopts the technical scheme that:

the utility model provides a knockout for cutting ring soil sample, includes stand, panel, pillar, handle, connecting rod and bulldoze the cone, a stand is all installed to four angular positions on the bottom surface of panel, the positive central point of panel puts and is provided with the cutting ring draw-in groove, be provided with the pillar on the positive terminal surface intermediate position of panel, be connected with the handle on the stand, the handle with the stand is connected through articulated fulcrum shaft, the handle is in order to rotate around articulated fulcrum shaft, be provided with the connecting rod on the handle, the center of connecting rod is just put to the central point of cutting ring draw-in groove, and the lower terminal surface of connecting rod is provided with the bulldoze cone, the summit of bulldozing the cone is just right the central point. The utility model discloses well cutting ring draw-in groove is used for laying cutting ring soil sample to play fixed limiting displacement, when the drawing of patterns of cutting ring soil sample, cutting ring soil sample is laid in the cutting ring draw-in groove, through manual twist grip, drives bulldoze the cone and release the cutting ring in soil sample, thereby in order to reach the purpose of swift drawing of patterns.

The upright post, the panel, the pillar, the handle, the connecting rod and the bulldozing cone are all made of steel, so that the service life of the equipment is prolonged.

The stand with four angles utilize cushion welded fastening to be connected on the bottom surface of panel, connect more firmly.

The panel is the rectangular plate, the panel is long 200mm, wide 120mm, thick 20mm, the sunken degree of depth 5mm in cutting ring draw-in groove upper portion, and suitable for reading diameter 76mm, end opening diameter 70mm make things convenient for people's production and preparation, also be convenient for people's operation and use.

The utility model has the advantages that: compared with the prior art, the soil sample pushing device comprises a stand column, a panel, a pillar, a handle, a connecting rod and a bulldozing cone, wherein the stand column is installed at four angular positions on the bottom surface of the panel, a cutting ring clamping groove is formed in the positive center of the panel, the pillar is arranged in the middle of one end surface of the front side of the panel, the handle is connected to the stand column and is connected with the stand column through a hinged support shaft, the handle rotates around the hinged support shaft, the connecting rod is arranged on the handle, the center of the connecting rod is just opposite to the center of the cutting ring clamping groove, the bulldozing cone is arranged on the lower end surface of the connecting rod, the vertex of the bulldozing cone is just opposite to the center of the cutting ring clamping groove, the soil sample pushing device is reasonable in design, simple in structure and convenient to produce and manufacture, therefore, the purpose of rapid demoulding is achieved, labor and time are avoided being wasted, the problems that hands are cut and the accuracy of experimental data is affected due to the fact that the cutting ring is deformed easily are avoided, and the device is more convenient, safe and reliable.
