Abstract
Description
Technical Field
[0001] The present application relates to the field of apparent density measuring instrument design, and in particular, to a device for measuring the apparent density of sand and gravel. Background Art
[0002] For sand and gravel aggregates used in concrete, the volume is measured using the liquid displacement method. The volume at this time is the sum of the solid volume and the closed pore volume, that is, it does not include the volume of open pores connected to the outside world. Since sand and gravel are relatively dense, there are few pores, and the open pore volume is even less, so the density measured by the liquid displacement method is also called apparent density.
[0003] When measuring, you need to first pour water into the bucket, then put the hanging basket into the bucket so that the water overflows the hanging basket, and finally record the volume of water discharged by the hanging basket. The common method is that the operator puts the water in a container for standby use, and when the bucket needs to be filled with water, lift the container filled with water above the bucket to fill the water. If the volume and height of the hanging basket to be measured are large, the amount of water required will be correspondingly large. The operator will need to consume more power to lift the water, and there will be a safety hazard that the container may slip from the operator's hand and break or even injure the operator himself.

[0030] Reference Figure 1-5 ,
[0031] A device for measuring the apparent density of sand and gravel includes: a bracket 1, an electronic scale 2, a water bucket 3, a water valve 4, a water pipe 5 and a hanging basket 6. The bracket 1 forms a support plane for placing the electronic scale 2, and the electronic scale 2 includes a weighing hook 16 formed with the lower end of itself, and the weighing hook 16 hooks the hanging basket 6 downward. The hanging basket 6 is placed in the water bucket 3, and a transverse through hole is formed on the side wall of the upper part of the water bucket 3. The water valve 4 is welded on the outer wall of the water bucket 3, and one end of the water valve 4 is connected to the through hole by docking. The water pipe 5 uses a flexible plastic pipe, and one end of the water pipe 5 is connected to the other end of the water valve 4 by clamping. When it is necessary to fill water into the water bucket 3, the operator connects the other end of the water pipe 5 with an external water source, and the external water source can be a tap. The tap and the water valve 4 are turned on, and water is injected into the water bucket 3 along the water pipe 5 and the water valve 4. When the drainage volume of the hanging basket 6 needs to be measured, the water pipe 5 is removed from the faucet and placed in a container, the water valve 4 is opened, and the water in the water bucket 3 flows into the container along the water valve 4 and the water pipe 5 .
[0032] In another embodiment, the water bucket 3 forms two groups of through holes, two groups of water valves 4 are provided, and two water pipes 5 are provided, and the through holes, water valves 4, and water pipes 5 are connected one by one. The operator connects one water pipe 5 to an external water source to inject water into the water bucket 3, and then puts another water pipe 5 in the container. When in use, the operator closes the water valve 4 connected to the water pipe 5 placed in the container, opens the water valve 4 of the water pipe 5 connected to the external water source, and water enters the water bucket 3 along a water pipe 5 and a water valve 4 to complete the water filling. Then, when it is necessary to measure the drainage volume of the hanging basket 6, the water valve 4 of the water pipe 5 connected to the external water source is closed, and the water valve 4 of the water pipe 5 connected to the container is opened, and the water flows into the container along another water valve 4 and another water pipe 5. The operator does not need to repeatedly plug and unplug a water pipe 5 from the external water source, which reduces the cumbersomeness of the operation.
[0033] Specifically, the bracket 1 includes: a first support plate 7, a column 8 and a base. The upper end of the first support plate 7 forms a support plane for placing the electronic scale 2, and a longitudinal clearance hole 9 is formed in the middle of the first support plate 7. The clearance hole 9 is located directly above the hanging basket 6 and the bucket 3. The weighing hook 16 is arranged on the lower end surface of the electronic scale 2 and penetrates the clearance hole 9 downward. The upper end of the column 8 is fixedly connected to the edge of the first support plate 7 by bolts, and the lower end of the column 8 is connected to the base.
[0034] Specifically, the base includes: a second support plate 10 and a bottom plate 11. The lower end of the column 8 is fixedly connected to the edge of the bottom plate 11 by bolts, and a slide groove 12 is formed at the upper end of the bottom plate 11. The slide groove 12 runs through one end of the bottom plate 11, and the second support plate 10 is embedded in the slide groove 12 and slidably cooperates with the slide groove 12, and the bucket 3 is placed on the upper end of the second support plate 10. Since the weight of the bucket 3 is large after it is filled with water, when the experiment is completed and the bucket 3 and the hanging basket 6 need to be taken out from the bracket 1, the first support plate 7 above the bucket 3 and the hanging basket 6 blocks them, and the bucket 3 and the hanging basket 6 cannot be directly lifted, and the friction between the bucket 3 and the base is large when moving the bucket 3 horizontally, which is also laborious. Therefore, a second support plate 10 is provided, and the operator can slide the second support plate 10 along the slide groove 12 in the direction where the slide groove 12 passes through one end of the bottom plate 11. The friction between the second support plate 10 and the slide groove 12 is small, so that the operator can pull the second support plate 10 with relatively little effort to move the bucket 3 and the hanging basket 6 out of the bracket 1.
[0035] Specifically, the bottom plate 11 further forms limiting grooves 13 on both sides of the chute 12, the length direction of the limiting grooves 13 is parallel to the length direction of the chute 12, and the length of the limiting grooves 13 is 3 cm larger than the diameter of the bucket 3. The second support plate 10 further forms limiting blocks 14 on both sides, the limiting blocks 14 protrude from the side of the second support plate 10, and the limiting blocks 14 are slidably matched with the limiting grooves 13. When the operator pulls the second support plate 10 until the limiting blocks 14 abut against the limiting grooves 13 toward the end of the chute 12 passing through the bottom plate 11, the operator can just lift the bucket 3 from above the second support plate 10, and the operator will not pull the second support plate 10 too much so that the second support plate 10 falls off from the end of the chute 12 passing through the bottom plate 11.
[0036] Specifically, it also includes a handle 15 . The handle 15 is fixedly connected to one end of the second support plate 10 that passes through the bottom plate 11 and faces the slide groove 12 by bolts. The operator holds the handle 15 to pull the second support plate 10 .
[0037] Specifically, four groups of columns 8 are provided, and the four groups of columns 8 are separated around the water bucket 3 to form four-point support, which firmly supports the first support plate 7 and the electronic scale 2.
[0038] Specifically, the electronic scale 2 further includes a weighing plate, which is disposed on the upper end surface of the electronic scale and is used to weigh the weight of the sample.
[0039] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used.
