Problems solved by technology

When installing the test tube, the test tube passes through the clamp seat and is tightened and fixed by bolts, but when the test tube is oscillated, the bolts may become loose due to the vibration caused by the operation of the box, resulting in insufficient clamping of the test tube by the clamp seat Tight, the test tube may be thrown out, which is dangerous and needs to be improved

Embodiment 1

[0038] A sand equivalent tester, such as figure 1 As shown, it includes a body 1 , a clamping seat 2 arranged on the body 1 , and a driving assembly arranged in the body 1 . When testing, the clamping seat 2 is used to clamp the test tube, and the driving assembly is used to drive the clamping seat 2 to move back and forth to oscillate the test tube.

[0039] The clamping seat 2 includes a lower base 21 and a cover plate 22 hinged on the lower base 21. The upper end surface of the lower base 21 is provided with a semicircular concave cavity 3, and the lower base 21 and the cover plate 22 are spliced ​​to form a test tube for installation. Circular installation chamber 4. The inner side walls of the lower base 21 and the cover plate 22 are all provided with rubber pads 5, and when the test tube is installed in the installation cavity 4, the rubber pads 5 are pressed against the outer side walls of the test tube.

[0040] like figure 1 , figure 2 As shown, the cover plate 2...

Embodiment 2

[0052] A sand equivalent measuring instrument differs from the first embodiment in that the structure of the fastening assembly 16 is different.

[0053] like Figure 5 , Figure 6 As shown, the side of the locking teeth 15 away from the cover plate 22 is arranged obliquely, and the side of the locking teeth 15 close to the cover plate 22 is arranged perpendicular to the length direction of the support rod 121 . The fastening assembly 16 includes a mounting base 164 disposed on the sliding base 122 , and a locking plate 165 hinged on the mounting base 164 . The mounting seat 164 is mounted on the top of the sliding hole 14 in a door shape, and the locking plate 165 is hinged in the door-shaped cavity of the mounting seat 164, and the hinge axis of the locking plate 165 is located in the middle of the locking plate 165 and parallel to the teeth of the locking teeth 15. surface settings. An end of the locking plate 165 close to the cover plate 22 is in contact with an inner w...

Abstract

The invention discloses a sand equivalent meter, relating to the technical field of concrete detection. The sand equivalent meter is characterized by comprising a machine body, a clamping base arranged on the machine body and a driving assembly arranged in the machine body, wherein the clamping base comprises a lower base and a cover plate hinged on the lower base, a semicircular concave cavity isformed in the lower base, the lower base and the cover plate form a circular mounting cavity through splicing, and the lower base is provided with a locking assembly; one end, in the axial directionof the mounting cavity, of the lower base is provided with a connecting rod, and a positioning plate is arranged on one end, away from the lower base, of the connecting rod; one end, in the axial direction of the mounting cavity, of the cover plate is provided with a mounting rod, the mounting rod extends toward one end opposite to the connecting rod, and one end, away from the connecting rod, ofthe mounting rod is provided with a baffle strip. When the meter is in an oscillating process, the flip opening and closing of the cover plate and the lower base make the operation of arranging a testtube into the clamping base more convenient; meanwhile, the axial direction of the test tube can be limited by means of the positioning plate and the barrier strip, such that the fixation of the testtube is more stable.

Description

technical field [0001] The invention relates to the technical field of concrete detection, in particular to a sand equivalent measuring instrument. Background technique [0002] The sand equivalent measuring instrument is a measuring instrument, suitable for asphalt mixture and cement concrete, using natural sand, artificial sand, stone chips, the maximum particle size of the aggregate is not more than 4.75mm, and measuring the cohesive soil or fine aggregate contained in the fine aggregate. The content of impurities is used to evaluate the cleanliness of the aggregate. The sand equivalent tester is an indispensable equipment for evaluating the cleanliness of fine aggregates in the construction of roads, bridges, buildings, railways, etc. [0003] Existing such as authorized announcement number is the Chinese utility model patent of CN2203454Y, discloses a kind of sand equivalent tester, comprises test tube and casing, and motor is housed in the casing, and motor drives lar...
