Technical Field
[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine which is convenient for sampling. Background Art
[0002] Frozen soil is a special type of soil with a temperature below zero and containing ice. It can be divided into perennial frozen soil and seasonal frozen soil according to the duration of its frozen state. Seasonal frozen soil refers to soil whose surface layer is frozen in winter and completely melts in summer. Seasonally frozen areas are usually hot and rainy in summer. This special climate causes problems such as frost heave and thaw settlement of highways, which makes basic transportation facilities such as pavement, roadbed, bridges and culverts easily damaged under the repeated effects of traffic loads and freezing, shortening the service life of the highway and increasing the cost of highway repair and maintenance. In order to solve the long-standing problem of seasonal frozen soil in highway construction, it is necessary to monitor it. At this time, a drilling machine is needed to sample and analyze the frozen soil.
[0003] Existing drilling machines usually use hand-held electric drilling machines to carry out geological sampling operations, which require continuous manual support to ensure that the drill bit is in a vertical direction and can extend to a sufficient depth underground. However, when the drilling machine is working, the groove inside the drill rod is often filled before the soil at the required depth is obtained, and the drill rod needs to be replaced or cleaned many times. The operation is cumbersome and it is impossible to collect samples in layers, which brings inconvenience to the sampling work of the drilling machine. Utility Model Content

A mounting seat is arranged inside the mounting frame, one side of the mounting seat is plugged into the mounting frame through a plug hole, and the other side of the mounting seat is threadedly connected to the threaded adjusting rod through a threaded hole. A collecting chamber is provided inside the mounting seat, and a sampling motor is installed on the top of the mounting seat, and the bottom of the sampling motor is connected to the sampling rod through an output shaft. A layered collection mechanism is arranged on the inner side of the mounting seat, and the layered collection mechanism is composed of a partition plate, a limit ring, an adjusting tooth block, an adjusting gear, a partition motor, a reserved groove and an adjusting plate.

After the new compartment is full, the above operation is repeated, which solves the problem that the drill machine cannot stratify the samples and accurately sample and collect them, which brings inconvenience to the sampling work of the drill machine.
[0017] 1. The drilling machine for easy sampling, in order to facilitate the sampling work, turns the adjustment plate to open the reserved groove, starts the separation motor to drive the adjustment gear, the adjustment tooth block, the separation plate and the limit ring to rotate through the coupling, and pushes the unnecessary soil on the upper side to the reserved groove and falls.

At this time, the driving motor is started, and the driving motor drives the driving gear, the transmission gear ring, the transmission gear and the rotating sleeve to rotate through the output shaft at the bottom. When the rotating sleeve rotates, it acts with the thread of the plug-in leg to drive the plug-in leg to plug downward until the abutment plate connected to the outside of the plug-in leg abuts against the frozen soil, thereby completing the stable position limiting of the drilling machine and preventing the phenomenon of slipping during the drilling process. The drilling machine which is convenient for sampling is provided with a stable placement mechanism, which can stably place the drilling machine on the upper side of the frozen soil, so that the drilling machine can stably perform sampling work.

[0029] During specific implementation, in order to facilitate the sampling work, the adjustment plate 407 is rotated to open the reserved groove 406, and the separation motor 405 is started to drive the adjustment gear 404 to rotate at a uniform speed through the coupling to engage with the adjustment tooth block 403, thereby driving the separation plate 401 and the limit ring 402 to rotate, and the unnecessary soil on the upper side is pushed to the reserved groove 406 and falls. When the required soil sample is obtained, the adjustment plate 407 is rotated to close the reserved groove 406 and the separation motor 405. At this time, the sampling motor 302 drives the sampling rod 303 to transport the soil sample to the separation chamber in the separation plate 401.
