Abstract

An object of the present invention is to integrate a funnel into a sample tray body, and to measure and measure sand in a test operation (test method for density and water absorption of JIS A 1109 fine aggregate and surface water rate test method of JIS A 1111 fine aggregate). To provide a tray with a funnel that prevents a series of human errors. A sample tray main body is provided with a funnel 7 and a short trumpet-shaped spout 6, a handle is provided at the upper part of the main body, the bottom is flat and well-placed for mounting on a scale, and a glass test is performed from sand measurement. A series of operations up to the insertion into the instrument can be performed on the tray with the funnel, thereby preventing human error. [Selection diagram] Fig. 1

Description

The present invention relates to a sample tray with a funnel.

  In the fine aggregate test, JIS A 1109 fine aggregate density and water absorption test method and JIS A 1111 fine aggregate surface water content test method, sand is measured with a tray or bat and the funnel is used. Samples were placed in test equipment (Pycnometer, Chapman flask).

  Solve the problems of human error (spillage, loss of work time, change in sand quality, error in test values, breakage of glassware) in handling sand after weighing.

  A container for measuring sand. The tray body has a substantially rectangular bottom, two long sides and one short side have walls raised from the bottom, and the other short sides from the bottom. The four side walls are continuous walls that prevent water leakage, and the inclined walls are parallel to the long sides of the two sides and the center is higher than the upper end of the wall. Constructed as part of a trumpet-shaped funnel with a small-diameter spout, with a handle at the top of the funnel, allowing the container to be stable with one hand during operation, and spilling when pouring from sand weighing into test equipment A tray with a funnel characterized by no leakage.

  When a sample is put into a glass test instrument (Pycnometer, Chapman flask), the spillage and sand quality change are eliminated, and the work time and test error can be reduced. A series of operations from weighing sand to putting it into glass test equipment can be performed with the tray with the inventive funnel to prevent human error.

Explanatory drawing which throws in a sample and measures. Explanatory drawing which pours a sample into a test device. Explanatory drawing which pours a sample into a test device.

  Place the tray body with a funnel on a scale and weigh about 500 g of sand at the tray. Tilt the tray with a funnel into the spout of a glass test device (Pycnometer, Chapman flask) and insert the spout into the sand. Remove the sand adhering to the inside of the tray with a brush and place it in a test instrument.

Embodiments of the present invention will be described below with reference to the drawings. The tray body 1 with a funnel has a base 2 having a substantially rectangular shape, a wall 3 raised from the long side of the bottom side, and a wall 4 raised from the short side of the bottom side. The short side has a wall 5 inclined upward from the bottom side, and these four side walls are continuous walls that prevent water leakage, and the inclined wall 5 is parallel to the long side of two sides and the center is It is configured as a part of a trumpet-shaped funnel 7 having a small-diameter spout 6 at a position higher than the upper end of the wall, and a handle 9 is provided on the top of the funnel 7. An inclined corresponding wall 8 is provided on the upper part of the funnel side wall 3 so that the tray does not overflow and spill out from the upper part of the funnel side of the wall 3 when the tray is poured into the test apparatus with the spout lowered. A tray with a funnel is characterized in that the container can be stabilized with one hand during operation, and there is no spillage or leakage when poured into the test equipment 11 from weighing sand.
The material of the present invention is made of plastic or polypropylene. By integrating the funnel and handle into the tray, the glass test equipment (Pycnometer, Chapman flask) and contact breakage are eliminated, and the measured sand is used as the test equipment. Can be poured directly. Since the bottom of the main body is placed on a balance, it sits flat and sits well, and the tip of the funnel spout fits the inside diameter of the spout of the test equipment and has a short trumpet shape to prevent clogging of sand. When the handle is tilted at the top of the funnel, the container can be stabilized with one hand.
FIG. 4 shows how the tray with funnel is used. A sample (fine aggregate) 10 is put into a tray with a funnel and weighed with a scale 12. FIG. 5 shows a situation where the test apparatus (Chapman flask) 13 is poured. FIG. 6 shows a situation where the brush 14 sample is removed.
