Problems solved by technology

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a sampler for road testing, which is convenient to dissipate heat from the drill bit during the drilling and sampling process of the drill bit, so as to avoid heat dissipation on the road surface and the feet of the sampling personnel through water heat dissipation. The problem of pollution, and the characteristics of avoiding the problem that it is difficult to dissipate heat on the drill bit when water resources are lacking in the outdoor sampling process, resulting in a decrease in the service life of the drill bit

Abstract

The invention belongs to the technical field of road detection, and particularly relates to a sampler for road detection, which comprises an outer frame, a second cylinder is mounted on the upper end surface of the outer frame, a lower connecting plate is mounted on the lower end surface of an upper connecting plate, a drill bit is fixedly connected to the lower end surface of the lower connecting plate, and a perforated plate is fixedly connected to the interior of the drill bit. A plurality of air inlet holes are formed in the upper end of the outer side wall of the drill bit in a penetrating mode, a plurality of air outlet holes are formed in the lower end of the outer side wall of the drill bit in a penetrating mode, a motor is installed on the lower end face of the lower connecting plate, the output end of the motor is detachably connected with a second rotating shaft, and fan blades are installed on the lower end face of the second rotating shaft. Therefore, the effect of conveniently cooling the drill bit by pumping air in the drilling and sampling process of the drill bit is achieved, the problem that the road surface and the feet of sampling personnel are polluted by water cooling is avoided, and the problem that the service life of the drill bit is shortened due to the fact that the drill bit is difficult to cool when water resources are insufficient in the outdoor sampling process is avoided.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a sampler for road detection. Background technique [0002] Urban road construction plays an important role in the existing urban construction system. Road paving is divided into base layer, cushion layer and surface layer; different layers have different corresponding materials and different physical properties of materials. In road construction In the later stage, samples will be collected for the road, and the quality inspection of the road will be carried out. [0003] Existing samplers for road testing use the water in the bucket to cool down the drill bit during drilling and sampling. Water heat dissipation is likely to pollute the road surface and the feet of the sampling personnel, and it is difficult to protect the drill bit when there is a lack of water resources in the outdoor sampling process. The effect of heat dissipation reduces the service life of the dril...
