Technical field
The utility model relates to a kind of machine that fetches earth, and relates in particular to a kind of Subgrade Compaction and detects with the machine of fetching earth.
Background technology
At present, the compactness of road foundation detects and adopts sand replacement method mostly, and promptly manually digging hole fetches earth on compacted subgrade, by pouring into the volume that the normal sand measurement is portalled, weight by earth in the volume in hole and the hole calculates the wet density of roadbed again, and then detects Subgrade Compaction.In testing process, borehole, the labour intensity that fetches earth, irritates process such as sand are big, and efficient is low, the waste normal sand.
Summary of the invention
The purpose of this utility model is to provide a kind of Subgrade Compaction to detect with the machine of fetching earth, with overcome on compacted subgrade manually digging hole, to fetch earth, irritate the labour intensity that process such as sand causes big, efficient is low, wastes drawbacks such as normal sand.
For achieving the above object, technical solution of the present utility model is: 1. a Subgrade Compaction detects with the machine of fetching earth, comprise support 1, bore cutter 2, sliding axle 4, web joint 7, loam cake 8, stroke adjustment nut 9, driving gear 11, follower gear 17, input shaft 13, casing 12, it is characterized in that: an end of described sliding axle 4 links to each other with brill cutter 2 by latch 3, and the other end links to each other with loam cake 8 with follower gear 17 respectively with screw thread by spline.
One end of described sliding axle 4 is provided with the screw thread that is used to install setting nut 9, and the other end is provided with and is used to install the pin hole that bores cutter 2.
Wheel 11 is nibbled in described active and follower gear 17 is a pair of intermeshing conical gears.
The beneficial effects of the utility model are: artificial shovel of the prior art is taken a cubic metre of earth formula be improved to machine drilling and fetch earth, be improved to the volume in automatic acquisition hole with the volume of irritating the sand measured hole, thereby alleviated testing staff's labour intensity, improved detection efficiency, having reduced sand replacement method uses the detection cost that normal sand brings and has that operation is simple and reliable, compact conformation such as is convenient for carrying at advantage.

Described driving gear 11 and follower gear 17 are that a pair of meshing circular cone is mutually nibbled wheel.
Manually ordering about input shaft 13 by handle 10 and rocking arm 14 rotates, the gear train of being made up of input shaft, one-level conical gear drives sliding axle 4, sliding axle when rotating be fixed on frame on loam cake 8 by the realization axial feed motion that is threaded, be installed in brill cutter 2 boring extracting soil in rotatablely moving of carrying out synchronously and feed motion on the sliding axle 4.Setting nut 9 is equipped with on the top of sliding axle 4, can control and measure the hole depth of going into that bores cutter, thereby by the drilling depth of adjusting, bore the cutter cross-sectional area, bore the volume in the cutter head portion good hole of centrum volume calculation, in taking out the hole all earth and weigh after can obtain the wet density of roadbed.
Rocking arm 14 is fastened on the input shaft 13 by key, driving gear 11 is installed on the input shaft 13 by interference fit, sliding axle 4, input shaft 13, follower gear 17 by Bearing Installation in casing 12, sliding axle 4 adopts spline to be connected with follower gear 17, sliding axle adopts with loam cake 8 and is threaded, loam cake 8, casing 12 are fastened on the web joint 7 by bolt, and web joint is fastened on the support 1 by bolt.
When using the utility model, the support 1 of the machine of fetching earth tramps with one's feet, with hand turning handle 10, power passes to rocking arm 14, input shaft 13, driving gear 11, follower gear 17, sliding axle 4 successively, bores cutter 2, sliding axle 4 be located at loam cake 8 in are threaded, when this screw thread rotates at sliding axle 4, promote sliding axle 4 and make axial feed motion, realize the boring extracting soil action.It is to be provided with a portable plate by support 1 side that earth is collected, and pulls down portable plate, earth is scanned out with electronic scale in the support measure.
The computing formula of boring volume:
V＝πD
2L/4+πD
2H/12
In the formula: D-bores the cutter diameter, and L-total kilometres, H-bore cutter conical section height, H=D * tan30 °/2
Roadbed wet density computing formula: ρ=P/V
In the formula: ρ-Ji soil density, the P-weight that fetches earth, the V-volume that fetches earth.
