Embodiment 1

[0033] figure 1 It is the front view of the soil trimming knife provided in this embodiment. Such as figure 1 As shown, the soil trimming knife provided in this embodiment includes a blade 1; a roller structure, which is installed on one side of the blade 1 and does not interfere with the scraping action of the blade 1, and the roller structure has a function for rolling Roller to level the surface of the sample.

[0034] By installing a roller structure on one side of the blade 1, the roller structure not only does not interfere with the scraping action of the blade 1, but also can roll the surface of the sample to be leveled, and the smooth curved surface of the roller can evenly contact the surface of the sample. Smooth rolling, the operator holds the soil repairing knife and alternately repeats the action of blade 1 scraping and roller rolling to complete the leveling of the sample surface. Compared with the scraping plane of the triangular scraper, the rolling surface o...

Embodiment 2

[0045] As an alternative to the first embodiment, this embodiment provides a soil repairing knife. The difference between the soil repairing knife and the first embodiment is that:

[0046] In the soil trimming knife provided in this embodiment, the roller structure is fixedly installed on the side surface of the blade through a fixed support structure, one end of the fixed support structure is connected to the roller structure, and the other end is connected to the blade of the blade. side surface connection.

[0047] Specifically, the fixed support structure includes a pair of support rods arranged correspondingly at intervals on one side surface of the blade along the extending direction of the length of the blade, and one end of each support rod is rotatable with the roller structure through a fixed shaft. connected so that the roller can rotate freely, and the other end is welded or bolted to the side surface of the blade.

[0048] It should be noted that the pair of sup...

Embodiment 3

[0050] As an alternative to the first embodiment, this embodiment provides a soil repairing knife. The difference between the soil repairing knife and the first embodiment is that:

[0051] In the soil trimming knife provided in this embodiment, the drum structure includes two cylinders with the same diameter, and the two cylinders are arranged coaxially above the knife back of the blade through a support structure, and the support structure is a T-shaped support frame , the lower end of the vertical part of the T-shaped support frame is connected to the back of the knife, and the two ends of the horizontal part of the T-shaped support frame are respectively inserted into the shaft holes of the corresponding end faces of the two cylinders, so that the two circles The barrels can rotate freely around the horizontal part of the T-shaped support frame as the axis.

[0052] It should be noted that the T-shaped support frame can be the movable support structure described in Embodim...

Abstract

The invention relates to a soil-trimming cutter which comprises a blade and a roller structure, wherein the roller structure is mounted on one side of the blade, does not interfere with a scraping action of the blade and is provided with a roller used for rolling a surface layer of a to-be-leveled sample. The soil-trimming cutter provided by the invention has the advantages of good leveling effect, operation flexibility and more accurate test result.

Description

technical field [0001] The invention relates to the technical field of soil engineering tests, in particular to a soil repair knife. Background technique [0002] Geotechnical tests can measure the physical, mechanical, chemical properties and mineral content of engineering soil in various forms, and provide scientific basis for engineering design and construction. The compaction test is to compact the soil sample in the laboratory to study the soil Basic method of compacting properties. During the test, the treated soil samples are first layered into the compaction cylinder, and the soil samples are hammered with a hammer until the compacted soil samples are filled with the compaction cylinder, and then the soil samples are separated by the demoulding machine, and Calculate the weight of the compacted soil samples. In order to ensure the accuracy of the test results, it is necessary to ensure the equal volume of different soil samples, that is, the volume of each soil sam...
