Embodiment 1

[0073] Please refer to Figure 1 to Figure 16 , the present embodiment proposes a hole-digging device for measuring the degree of road surface compaction by sand-filling method, including a hole-digging assembly 1 and a bottom plate 2, and the bottom plate 2 is provided with a standard round hole 21; specifically, the hole-digging Hole assembly 1 is used for digging holes, and the effect of described bottom plate 2 mainly has two, one is to dig holes by using the standard round hole 21 arranged on it as a reference, on the other hand, by setting the bottom plate, it is convenient to dig out The soil is placed on the base plate 2, which is convenient for collecting the excavated soil.

[0074] For specific implementation, please refer to Figure 1 to Figure 17 , the improvement of this embodiment is that it further includes a support assembly 3 and an adjustment assembly 33 . In this embodiment, the support assembly 3 is provided on the one hand to realize the adjustment asse...

Embodiment 2

[0101] This embodiment is an improvement made on the basis of embodiment 1, and the similarities will not be repeated. The main difference is that the diameter of the head of the hole digging assembly 1 is smaller than the diameter of the standard circular hole 21 . That is, the diameter of the hole dug by the hole digging assembly 1 is smaller than the diameter of the standard round hole 21 .

[0102] In practical application, if the standard circular hole 21 and the hole-digging assembly 1 are to be completely centered through the four positioning mechanisms 333, the precision requirements for the four positioning mechanisms 333 are extremely high, that is, the four positioning mechanisms 333 must be positioned When the force and elongation are exactly the same. For this reason, by setting the diameter of the head of the hole digging assembly 1 to be smaller than the diameter of the standard round hole 21, the requirement for accuracy can be reduced. During implementation, ...

Embodiment 3

[0104] This embodiment is an improvement made on the basis of Embodiment 1. Specifically, in order to limit the rotation of the housing of the motor 11, a baffle 321 is connected to the adjustment plate 32, and the function of the baffle 321 is to limit the rotation of the motor 11. The housing of 11 rotates so that the drive shaft 12 can produce enough moment to excavate the earth.

[0105] In specific use, embodiment 1 can be positioned through the adjustment assembly 33 , and in use, the housing of the motor 11 can press the adjustment cylinder 331 to realize the downward pressure and quick adjustment of the adjustment assembly 33 . However, during this process, the motor 11 is working, which is prone to interference.

[0106] For this reason, present embodiment has been further improved:

[0107] Please refer to Figure 10 to Figure 12 and Figure 18 In this embodiment, a locking assembly 5 is added, and the locking assembly 5 is used to keep the adjustment barrel 331 i...

Abstract

The invention discloses a hole digging device which comprises a hole digging assembly and a bottom plate, and standard round holes are formed in the bottom plate. The device comprises a supporting assembly, and the supporting assembly is used for being in sliding connection with an external vehicle in the vertical direction; a first sliding rail and an adjusting plate which are horizontally arranged are arranged on the supporting assembly, and the adjusting plate is parallel to the first sliding rail and located above the first sliding rail; the bottom plate is connected with the first sliding rail in a sliding fit mode. The adjusting assembly is connected with the adjusting plate, and the adjusting assembly is used for adjusting the position of the bottom plate; the hole digging assembly is arranged on the adjusting assembly, so that the hole digging assembly can be aligned with the standard round hole after penetrating through the adjusting assembly; and the hole digging assembly is used for digging holes along the standard round holes after the adjusting assembly adjusts the bottom plate in place. The high-precision detection hole can be used for detecting the compactness of the roadbed through the sand filling method.

Description

technical field [0001] The invention relates to the technical field of roadbed compaction detection, in particular to a hole digging device. Background technique [0002] The detection of subgrade compaction is a routine detection test in the process of road construction, and the commonly used detection method is the sand filling method. That is, usually, holes are dug on the road, and standard sand is poured into the hole, and the degree of compaction of the subgrade is calculated by measuring parameters such as the weight of the excavated soil, moisture content, and the quality of the standard sand poured in. However, the method of sand filling to measure the degree of subgrade compaction has high requirements for the operation of testers, and there are many factors that may easily lead to errors during the test process. For example, the accumulation of measurement errors, the accuracy of digging holes, and the loss of water in the excavated soil. [0003] Among various ...
