Base layer sampling device for highway construction

Abstract

The invention relates to a base layer sampling device for highway construction. The base layer sampling device comprises a connecting plate, wherein a sampling mechanism is arranged on the connectingplate; side plates are arranged on the edges of two sides of the connecting plate; supporting plates are arranged on the edges, which are far away from the connecting plate, of the side plates on twosides; rollers are arranged below the supporting plates on two sides; inserting rods are arranged on the supporting plates in a penetrating manner and are connected with the supporting plates in a sliding manner; plate bodies are arranged on the side walls of the inserting rods and are positioned at positions close to the connecting plate; a plurality of first springs are arranged between the plate bodies and the supporting plates; one end of each first spring is fixedly connected to the corresponding plate body, and the other end of each first spring is fixedly connected to the correspondingsupporting plate; and connecting pieces for driving the inserting rods to be inserted into or separated from the ground are arranged on the supporting plates. The base layer sampling device disclosedby the invention has the advantage that the sample drilling stability of the sample drilling device is improved.

Description

technical field [0001] The application relates to the field of road construction equipment, in particular to a grass-roots sampling device for road construction. Background technique [0002] In the early stage of highway engineering construction and during the construction process, it is necessary to sample and analyze the subgrade soil samples of the original ground of the highway engineering to ensure the quality of highway construction. [0003] The Chinese patent with the authorized announcement number CN202380452 discloses a road base compaction detection device for road construction, including a support plate, a driven rack bar, a driving gear, a rotating shaft, a motor, a support leg, a stabilizing plate, a sampling cylinder and an unloader. feed hole. Wherein, a support leg is provided under the square support plate, a circular stabilizing plate is provided at the lower end of the support leg, a motor is provided above the support plate, and a driving gear is conne...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following technical defects: when in use, the supporting legs drive the stabilizing plate to be placed on the ground, and the motor drives the driving gear to rotate, so that the driving gear drives the driven rack bar to rotate, and the driven rack bar rotates. The rack bar can move on the support plate, so that the driven rack drives the sampling cylinder to take samples. When the sampling cylinder touches the ground, it can easily drive the support plate to move on the ground, so that the sampling cylinder deviates from the sampling position, reducing the overall Stability of the sampling device when sampling on the ground
