Abstract
The utility model discloses a detecting and sampling device for compactness measurement of a road base. The detecting and sampling device is high in sampling accuracy and easy to control. The detecting and sampling device comprises a supporting device, wherein a driving device is arranged above the supporting device, a lengthening bar is arranged below the supporting device in the vertical direction, one end of the lengthening bar is connected with the driving device, the other end of the lengthening bar is connected with a shovel head, the driving device is connected with the lengthening bar through a screw rod, the shovel head is a semicylindrical, and the longitudinal section of the shovel is shaped as a trapezoid which is narrow in upper part and wide in lower part. According to the device disclosed by the utility model, the shovel head is of a structure similar to a Luoyang shovel used in archaeological work and is convenient to sample and ideal in effect; and the driving device is used for driving the screw rod to control the lengthening bar to move up and down, and therefore, the sampling device is favorable in controllability and high in accuracy of up-and-down displacement.
Description
Technical field
The utility model relates to a kind of sampler, is specifically related to a kind of road base layer degree of compaction and detects sampler.
Background technology
For many years in highway engineering construction, the sampling method of its road base layer, subbase degree of compaction (sand replacement method) adopts ancient mode of operation always, namely operated with heavy simple and crude instruments such as hammer, screwdriver, flat chisels by artificial, with regard to whole process, need artificial many, use duration, sample moisture content is easily lost, and large to perturbing property of the soil body, and it is rough that perisporium is cheated in sampling, the sampling weak effect, accuracy is not good enough.
Chinese patent 201120579524.2 discloses a kind of construction of the highway and has detected sampler with the road base layer degree of compaction, rotating by the both forward and reverse directions of controlling motor the both forward and reverse directions that drives driving gear rotates, and then drive the driven rack bar be engaged with connection and move up and down, can utilize the sampling tube that is connected to driven rack bar end to realize sampling.But when adopting this mode to control shovel head to move up and down, accuracy is not high, wayward, and sampling tube sampling effect is undesirable.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of road base layer degree of compaction to detect sampler, and the sampling accuracy is high, and easily controls.
For achieving the above object, the utility model adopts following technical proposals:
A kind of road base layer degree of compaction detects sampler, comprise bracing or strutting arrangement, the top of bracing or strutting arrangement is provided with drive unit, the below in the vertical direction of bracing or strutting arrangement is provided with extension bar, one end of extension bar is connected with drive unit, and the other end is connected with the shovel head, and described drive unit is connected with extension bar by leading screw, described shovel head be semi-cylindrical shaped, and the vertical section of shovel is one up-narrow and down-wide trapezoidal.
Described bracing or strutting arrangement comprises gripper shoe and the supporting leg that is positioned at the gripper shoe below, and the lower end of described supporting leg is provided with base.
Described drive unit comprises motor, and the rotating shaft of described motor is connected with leading screw.
Described leading screw is ball-screw.
Described trapezoidal lower base angle is 80 ° ~ 85 °.
Described trapezoidal lower base angle is 83 °.
The beneficial effects of the utility model are that the shovel head has adopted the structure of the luoyang spade that uses in similar archaeological work, takes a sample convenient, satisfactory for result; Utilize drive unit to drive leading screw and control moving up and down of extension bar, controlled good, the accuracy of upper and lower displacement is high.
Description of drawings
Fig. 1 is the utility model structural representation;
1. gripper shoes wherein, 2. extension bar, 3. ball-screw, 4. shovel head, 5. motor, 6. supporting leg, 7. base.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further set forth, should be noted that following explanation is only in order to explain the utility model, its content not to be limited.
As shown in Figure 1, the utility model comprises bracing or strutting arrangement, and bracing or strutting arrangement comprises gripper shoe 1 and the supporting leg 6 that is positioned at gripper shoe 1 below, and the lower end of supporting leg 6 is provided with base 7; The top of bracing or strutting arrangement is provided with drive unit, and the below in the vertical direction of bracing or strutting arrangement is provided with extension bar 2, and an end of extension bar 2 is connected with drive unit by ball-screw 3, and drive unit comprises motor 5, and the rotating shaft of motor 5 is connected with ball-screw 3; The other end of extension bar 2 is connected with shovel 4, and shovel 4 is semi-cylindrical shaped, and to shovel a vertical section of 4 be one up-narrow and down-wide trapezoidal, and trapezoidal lower base angle is 83 °.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
