Description

[Detailed explanation of the idea] In the process of conducting a triaxial compression test, it is necessary to prepare a specimen. Conventionally, before a test, a weight table was created in which the weight of each particle size of the sample was determined, and based on the same weight table, each particle size was put into a Hoppa scale and weighed, and the weighed sample was called the specimen. Once lowered near the preparation location, the sample is mixed by input using a scoop, etc. The thus mixed sample is placed in a container that can be held by hand, and transported into the mold in the manner of a fishing bottle.

Continuing this work for a long time was hard work, and there were also difficulties in terms of work efficiency.

The present invention was proposed in order to eliminate such drawbacks, and includes a bottom plate 2 formed by welding a plurality of inverted V-shaped pieces 1 extending in the width direction at predetermined intervals on the surface of the bottom plate 2, which are pivoted to open and close freely. This relates to an aggregate mixer characterized in that a lifting cable connecting piece 5 is disposed at a corner of the upper end opening of a container body 4.

In the illustrated embodiment, angle steel is used as the inverted V-shaped piece 1, and is welded to the bottom plate 2. Further, a latch 7 equipped with an opening/closing handle 6 is rotatably attached to the side wall of the container body 4, and a tip hook portion 7a of the latch 7 is pivotally attached to the container body 4 in a double-opening manner.
It is configured to engage and disengage from end plates 9 disposed on both sides of each tip of a pair of bottom plates 2. In the figure, reference numeral 10 denotes a reinforcing plate attached to the container body 4 at the attachment portion of the latch 7.

Since the present invention is constructed as described above, the aggregate mixer of the present invention is placed on the weighing trolley a in place of the conventional hopper b (see Fig. 6).
The aggregate is weighed in the conventional manner, and when the weighing is completed, the suspension cable c is connected to the suspension cable connection piece 5 provided at the corner of the upper opening of the container body 4, and the ceiling crane is connected. (not shown), hang it inside the mold d, and rotate the opening/closing handle 6 on the bottom plate e or directly above the sample A placed earlier.
The engagement between the tip hook 7a of the latch 7 and the end plate 9 of the bottom plate 2 is released to bring the bottom plate 2 into a state where the lid can be opened, and then the container main body 4 is lifted by a ceiling cleaner via the lifting cable c. Gradually lift it up.

At this time, the sample A' in the container body 4 slowly flows out from the bottom of the container body.

Note that FIGS. 7 to 12 show the process of discharge from the aggregate mixer, in which large-diameter aggregates are first introduced into the container body 4, and then small-diameter aggregates are introduced into the container body 4. Large diameter aggregate is placed below the container body.
Sample A' is filled into the container body 4 so that the small-diameter aggregate is located at the top. (See Figure 7) In this state, the container body 4 is gradually lifted up via the lifting cable C, and the sample A' falls from the body 4 by releasing the bottom plate 2 due to its own weight.
In the sample, a part of the large-diameter aggregate is temporarily blocked by the inverted V-shaped piece 1 on the bottom plate 2, while a part of the small-diameter aggregate above the large-diameter aggregate is part of the large-diameter aggregate. (See Fig. 8) These actions occur one after another as shown in Figs. The container body 4 is in a mixed state almost the same as that mixed externally.
more excreted.

Note that the sample A discharged in this manner is finally leveled at the top and compacted using a vibrator.

When the discharge of the sample in the container body 4 is completed, the main body 4 is mounted on the weighing cart a again, and the tip hook 7a of the latch 7 is locked to the end plate 9 of the bottom plate 2, and the bottom of the container body 4 is The lid is closed and the next layer is weighed.

According to the present invention, the container body 4 containing the sample is lifted and suspended by a ceiling crane using the lifting cable connecting piece 5 disposed at the corner of the upper end opening of the container body 4. This greatly saves labor, and by opening the bottom plate 2 which is pivotally attached to the container body 4 so that it can be opened and closed, the sample inside the container body 4 can be molded into the mold bottom plate.
Alternatively, the sample is discharged directly above the mold that was previously placed in the mold, so there is no damage to the sample, and as the sample is discharged, the sample is mixed by the inverted V-shaped piece 1 on the bottom plate 2 and discharged. According to this proposal, the surrounding area will not be dirty and there will be less dust, improving the working environment.
