Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment discloses a soil compaction instrument, as shown in fig. 1, comprising a base 1 and a support ring 2 fixed above the base 1 through a connecting rod 3, wherein a compaction cylinder 4 with an upper opening and a lower opening is arranged on the base 1, and a compaction hammer 5 capable of compacting a sample in the compaction cylinder 4 is arranged in the compaction cylinder 4;

the side wall of the compaction cylinder 4 is fixed with a fixed wing 6 which can slide up and down along the connecting rod 3, and the fixed wing 6 is provided with an adjusting rod 7 which can drive the fixed wing 6 to move up and down.

When the soil compaction device works, the base 1 part is connected according to the mode, then a sample is prepared, the compaction hammer 5 is lifted, the sample is placed in the compaction barrel 4, and then the sample is compacted under the action of the compaction hammer 5 to measure the sample. Wherein the outer diameter of the compaction hammer 5 is matched with the inner diameter of the compaction cylinder 4, and the compaction hammer 5 has a certain thickness, so that the compaction hammer 5 is prevented from being inclined. The fixed wing 6 can play the role of auxiliary fixation to prevent the compaction cylinder 4 from rotating.

After the sample is tested, the length of the adjusting rod 7 is adjusted to enable the fixed wing 6 to lift the compaction cylinder 4, after the fixed wing rises to a certain degree, the sample is exposed, the sample can be brushed away by using a brush, then the compaction cylinder 4 is reset, and the operation is repeated.

The adjusting rod 7 in this embodiment is further optimized, the top end of the adjusting rod 7 penetrates through the support ring 2 and is fixed with a first limiting block 71 through threads, and the bottom end of the adjusting rod 7 penetrates through the fixed wing 6 and is detachably connected with a second limiting block 72.

When the compaction device is used specifically, the second limiting block 72 is fixed at the bottom of the adjusting rod 7, at this time, the second limiting block 72 plays a role in supporting the fixed wing 6, and then the distance between the first limiting block 71 and the second limiting block 72 of the adjusting rod 7 is adjusted by rotating the first limiting block 71, so that the compaction cylinder 4 is lifted or lowered. The first stopper 71 may be a nut or other threaded structure capable of performing this function.

The connecting structure of the fixed wing 6 and the adjusting rod 7 in this embodiment is further limited, as shown in fig. 2, a through hole is provided on the fixed wing 6, the adjusting rod 7 sequentially includes an adjusting portion 73, a pressing portion 74 and a fixing portion 75 from top to bottom, the diameter of the pressing portion 74 gradually decreases from top to bottom, and the maximum diameter of the pressing portion 74 is larger than the minimum diameter of the through hole, which is larger than the aperture of the through hole, of the pressing portion 74.

The downward pressing part 74 of adjusting the pole 7 is from last to reducing gradually down the diameter, and the through-hole can be passed to the bottom, and the top is because the diameter is too big can't pass the through-hole, adjusts the in-process of pole 7 extension, adjusts the pressure that pole 7 provided for stationary vane 6 and also can increase gradually, can will hit solid section of thick bamboo 4 firm compressing tightly on base 1, avoids influencing measuring effect because hitting rocking between solid section of thick bamboo 4 and the base 1.

The second stopper 72 is disposed on the fixing portion 75, so that when the compaction cylinder 4 is lifted, a supporting force is provided for the compaction cylinder 4, thereby facilitating the lifting of the compaction cylinder 4.

The connection relation between the fixing portion 75 and the second limiting block 72 is further optimized, and the fixing portion 75 and the second limiting block 72 are connected through threads, clamping or bolts, so that the mounting and dismounting are facilitated.

The structure of the base 1 is further optimized, a sample placing table 8 is arranged on the base 1, and the shape and the size of the sample placing table 8 are matched with the inner diameter of the compaction cylinder 4.

The sample rest 8 has a limiting function on one hand and is used for positioning the compaction cylinder 4, and in addition, the sample rest 8 can be arranged at a certain height so as to avoid the compaction cylinder 4 from being inclined.

The internal structure of the compaction cylinder 4 is further optimized, as shown in fig. 1, since fig. 1 cuts the side wall of the compaction cylinder 4, the structure in the compaction cylinder 4 can be seen, a pressure member 9 is arranged in the compaction cylinder 4, the pressure member 9 is arranged between the compaction hammer 5 and the sample, and the outer diameter of the pressure member 9 is matched with the inner diameter of the compaction cylinder 4.

The pressure member 9 should also have a certain thickness to avoid inclining, and the existence of the pressure member 9 prevents the sample from directly contacting with the compaction hammer 5, thereby avoiding that part of the sample is attached to the compaction hammer 5 in the process of continuous rising and falling of the compaction hammer 5 to influence the surface smoothness of the sample, and further influencing the accuracy of the measurement result.

The structure of the pressure piece 9 is further optimized, two fixing columns are arranged on the pressure piece 9, the top ends of the two fixing columns are connected through a fixing plate 10, a control rod is connected to the compaction hammer 5, and the top end of the control rod penetrates through the fixing plate 10 to be connected with a gripper located above the fixing plate 10.

The fixing plate 10 has a limiting function on the compaction hammer 5, and is convenient to control the control rod.

The compaction hammer 5 is further optimized, a sliding hole is formed in the compaction hammer 5, and a sliding rod which moves up and down in the sliding hole is fixed on the pressure piece 9.

The impact hammer 5 can be prevented from being inclined and impacting the side wall of the impact barrel 4, so that the impact barrel 4 is inclined, and the accuracy of a result is influenced.

The compaction hammer 5 is further optimized, and the compaction hammer 5 is provided with air holes communicated with the sliding holes, so that the phenomenon that the internal pressure of the sliding holes is increased under the action of the sliding rods to block the movement of the compaction hammer 5 is avoided.
