Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses backfill soil detector.

Example 1:

referring to fig. 1, the backfill soil detector comprises a detector body 1, and a conversion interface is arranged on the side wall of the detector body 1. The conversion interface is internally detachably connected with a probe rod 2, and the probe rod 2 can be adjusted to different models according to different detection situations. One end of the probe rod 2, which is far away from the detector body 1, is provided with a tip, a boss or a thread, so that the probe rod 2 can more easily extend into the soil. The differently shaped ends also accommodate different soil qualities. The surface of the probe rod 2 is provided with scales, and when the probe rod 2 extends into the soil, the depth of the probe rod extending into the soil can be detected. The periphery of the probe rod 2 is inserted with a display ring 3, the display ring 3 can be made of rubber, and the display ring 3 can slide along the length direction of the probe rod 2. When the probe 2 is inserted into the soil, the display ring 3 can be limited to the surface of the backfill soil, so that the depth of the insertion into the soil can be read through the display ring 3.

The periphery of probe rod 2 has cup jointed spring 4, and the one end fixed connection of spring 4 is on the lateral wall of detector body 1. The other end of the spring 4 is fixedly connected with a sleeve 5, and the sleeve 5 is inserted at the periphery of the probe rod 2. The diameter size of probe rod 2 and the internal diameter adaptation of sleeve 5 and spring 4 make probe rod 2 be difficult for rocking in sleeve 5 and spring 4, make the height that detects more accurate. The inner diameter of the sleeve 5 is smaller than the outer diameter of the display ring 3, and when the probe rod 2 extends into the soil, the display ring 3 can be limited between the backfill surface and the sleeve 5 by the sleeve 5. Seted up bar hole 51 on sleeve 5's the lateral wall, bar hole 51 is used for showing the scale, need not to take out probe rod 2, can read the degree of depth in the soil of inserting when probe rod 2 is located the backfill soil.

One end screw thread fixedly connected with support frame 6 of spring 4 is kept away from to sleeve 5, and support frame 6 includes a plurality of bracing pieces 61, and bracing piece 61 is cylindricly. The ends of the plurality of support rods 61 near the ground are flared. The support frame 6 enables the detector to be stably manufactured on the surface of the backfill soil to be detected, and the probe rod 2 can vertically extend into the soil approximately, so that the measured depth is more accurate. The supporting rod 61 is welded with the fixing piece 7 at one end close to the backfill soil surface, and the fixing piece 7 is square. The stator 7 and the support bar 61 may be made of a light material such as plastic, which reduces the overall weight of the monitor. The fixing piece 7 increases the contact area of the support rod 61 and the surface of the backfill soil, reduces the pressure of the whole detector on the surface of the backfill soil, and enables the support rod 61 not to penetrate into the soil easily.

The implementation principle of the embodiment 1 is as follows: place bracing piece 61 on the surface of backfill soil, press detector body 1, spring 4 will compress, will detect in the backfill soil with probe rod 2 impressing, is provided with the scale on probe rod 2, can directly observe the degree of depth that probe rod 2 stretched into in the backfill soil through bar hole 51 at the in-process that probe rod 2 stretched into the soil. When the detection is finished, the probe rod 2 can be conveniently taken out of the backfill soil by virtue of the elasticity of the spring 4.

Example 2:

referring to fig. 1, the present embodiment is different from embodiment 1 in that a probe 2 is composed of a first probe 21 and a second probe 22. The first probe rod 21 is fixed in the conversion interface in a threaded manner, the first probe rod 21 is hollow, and the second probe rod 22 is connected in the first probe rod 21 in a sliding manner. A plurality of arc-shaped clamping grooves 221 are formed in the side wall of the second detecting rod 22, and the clamping grooves 221 are arranged along the length direction of the second detecting rod 22. The inner wall of the first probe rod 21 is provided with a clamping protrusion 211 which is inserted into the second clamping groove 221 in a matching manner. The joint groove 221 and the joint protrusion 211 are connected in an adaptive mode, the first probe rod 21 and the second probe rod 22 can stretch out and draw back, the length can be adjusted to adapt to different detection conditions, and the use and the storage are more convenient.

The implementation principle of the embodiment 2 is as follows: the first probe rod 21 and the second probe rod 22 are connected in a telescopic manner, and the overall length of the probe rod 2 can be adjusted to adapt to different detection situations. The clamping groove 221 and the clamping protrusion 211 are inserted in a matched mode, so that when the second probe rod 22 is inserted into the backfill soil, the first probe rod 21 and the second probe rod 22 are not prone to sliding, and the second probe rod cannot smoothly extend into the soil.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
