The roadbed detection sampler is characterized in that a coupling (6) is arranged on the lower portion of the power device (3), a cutter head (10) is mounted at the lower end of a transmission rod (14) fixed to the coupling, a soil accommodating disc (15) is arranged on the lower portion of the framework, a center hole is arranged on the bottom surface of the soil accommodating disc, and the diameter of the center hole is larger than that of the cutter head. The roadbed detection sampler has the advantages that the rotary sampling cutter head is used for taking samples from portions with specific diameters and depths, and the roadbed detection sampler is simple, convenient and speedy, and is high in detection precision and low in cost; and collection operation can be omitted owing to the soil accommodating disc, and the roadbed detection sampler is simple in integral design and easy to maintain and disassemble.

Description

Roadbed detects sampler

Technical field

The utility model relates to a kind of highway subgrade degree of compaction sampling detecting device, is specially a kind of roadbed and detects sampler.

Background technology

In road construction, the detection of the matrix of satisfying the need amount is absolutely necessary, and the design of the drilling tool of the drill hole sampling machine of usefulness is very complicated usually, be difficult for maintaining, and long-time service precision reduction, testing result influenced, if run into softer detected material, then may further reduce the precision of sampling.Chinese patent 98209558.9 discloses a kind of " core-drilling machine ", and by support, guide pillar, slide block stationary engine are by the operation of taking a sample of motor driven main shaft and core drill.It is mainly used in rigid pavement or flexible pavement sampling.Chinese patent 201120579524 disclosed " a kind of construction of the highway detects sampler with the road base layer degree of compaction ", fixed support plate on support arranges motor in gripper shoe, realizes the roadbed sampling by motor-driven rotatable shaft, tooth bar and sampling tube.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of simple structure, and the roadbed that is easy to safeguard detects sampler.

The technical solution adopted in the utility model is: a kind of roadbed detects sampler, comprise frame, frame is provided with vertical guide pillar, elevating stage is connected with frame by the rolling bushing with vertical guide pillar coupling, fix dynamic device at elevating stage, and screw is arranged fixedly also on elevating stage, coupling has trapezoidal screw in wire master hole, there is handwheel on described trapezoidal screw top, it is characterized in that shaft coupling is arranged at the power set bottom, the drive link lower end that fixes with described shaft coupling is equipped with cutter head, is provided with soil holding disk in frame lower, and the bottom surface of described soil holding disk has a diameter greater than the centre bore of tool bit diameter.

Described roadbed detects sampler, it is characterized in that frame lower fixedly has a bearing support, and bearing fixing is in bearing support, and the bottom of drive link is socketed in the bearing.

Described roadbed detects sampler, it is characterized in that being equipped with on the frame scale of advancing, and in the frame bottom taper leg is installed.

Roadbed of the present utility model detects sampler and is specially adapted to adopt the sampling cutter head of rotation to take a sample in special diameter and the degree of depth in the operation of taking a sample of the highway subgrade of compacting, and is both easy, quick, the accuracy of detection height, and also cost is very low.The application of soil holding disk can be saved the collection operation, and its global design is simple, for ease of maintenaince dismounting.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the K of Fig. 2 is to view.

Among the figure, 1-handwheel, 2-trapezoidal screw, 3-power set, 4-elevating stage, 5-screw, 6-shaft coupling, 7-rolling bushing, the vertical guide pillar of 8-, 9-bearing, 10-cutter head, 11-leg, the 12-scale of advancing, 13-frame, 14-drive link, 15-soil holding disk, 16-bearing support.

The specific embodiment

As Figure 1-3, frame 13 is square structure, one quadra is arranged at its top, be separately installed with the vertical guide pillar 8 of vertical direction at two inner side edges (bottom as shown in Figure 2 and right part inner side edge) of quadra, an elevating stage 4 is arranged in quadra, fixedly there is the rolling bushing 7 that mates with vertical guide pillar 8 in the outside of described elevating stage 4 with described vertical guide pillar 8 correspondence positions, by described guide pin bushing 7 and guide pillar 8 elevating stage 4 and frame 13 are connected as one, and elevating stage 4 can be along vertical guide pillar 8 upper and lower movements.Drift angle one side relative with two limits at described guide pin bushing 7 places on elevating stage 4 fixedly has screw 5, and coupling has trapezoidal screw 2 in screw 5, and handwheel 1 is arranged at the top of described trapezoidal screw 2.Can control lifting and the decline of elevating stage 4 by the positive and negative rotation of handwheel 1.Dispose power set 3 at elevating stage 4, the power set of present embodiment adopt Diesel engine.The output shaft of power set 3 is positioned at the bottom, at output shaft shaft coupling 6 is arranged fixedly, and what be connected with shaft coupling 6 is drive link 14, in drive link 14 lower ends cutter head 10 is arranged fixedly.Described cutter head 10 can adopt straight line cutter or helical form cutter, and the utility model has adopted the straight line cutter head for the accuracy that guarantees to take a sample.In order to guarantee drive link 14 steady operations, in frame lower a bearing support 16 is set, this bearing support is the crossbeam that is fixed on frame lower as shown in Figure 1, bearing 9 is fixed on the shaft core position with drive link 14.Drive link 14 is socketed in the bearing 9.Also be provided with a soil holding disk 15 in bearing support 16 bottoms, there is a diameter bottom of this soil holding disk greater than the centre bore of cutter head 10 diameters, and both diameter differences are about 2-4 centimetre.The soil that cutter head sweeps during work can directly enter in the soil holding disk.In order to keep the stable state of sampler when working, be provided with four corresponding taper legs 11 in frame 13 bottoms, simultaneously in order to ensure the accuracy of taking a sample, also be provided with the scale 12 of advancing in the frame inboard, during work, 0 degree line of scale is the original position that cutter head is in rolling bushing 7 when taking a sample original horizontal position.

During work, frame is placed on the sampling face of surfacing, make the bottom surface of soil holding disk 15 be close to the face of land, rotate handwheel, cutter head touches ground to blade straight down, determine to advance after the zero-bit of scale 12, the device 3 that turns on the power rotates handwheel, and cutter head is slowly descended, screwed out the soil sample of coming by cutter head 10 in the decline process and enter soil holding disk 15, when cutter head 10 drops to the setting depth selection, close power set, read the shift value on the scale 12 of advancing, calculate sample volume according to tool bit diameter, collect in the soil holding disk 15 and remain in all the tested soil samples in the thief hole and weigh.Calculate Subgrade Compaction according to irritating the micromicrofarad experimental procedure.
