Description

Technical Field

[0001] The utility model relates to the technical field of dynamic compaction machines, and specifically relates to a new type of dynamic compaction machine. Background Art

[0002] A dynamic compaction machine is a mechanical device that compacts soil using principles such as dynamic compaction, dynamic consolidation, or dynamic replacement. According to different working principles and application scenarios, there are various types of dynamic compaction machines, including frog type, vibration type, leap step type, ramming type, and suspended heavy hammer impact type, etc.

[0003] Currently, the dynamic compaction machines on the market need to be measured again after compaction, which increases the workload; and when they rise during each compaction, they will cause impact on the outer shell. In the long run, it is easy to cause damage to the outer shell and reduce the stability.

[0004] Therefore, it is necessary to design a new type of dynamic compaction machine to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of dynamic compaction machine to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

A first tool compartment is arranged at the rear of the driver's cab. Wheels are installed at the front and rear ends of both the left and right sides of the vehicle body. A vertical outer shell is arranged at the front end of the vehicle body. A second hydraulic rod is fixedly installed above the interior of the outer shell. The bottom output end of the second hydraulic rod is connected to a piston rod. The top of the piston rod is fixedly connected to a hammer head located outside the bottom of the outer shell. A distance measuring device is fixedly installed below the front side of the outer shell.

[0008] As a preferred scheme of the utility model, a clamp is fixedly connected to the outer shell of the second hydraulic rod through bolts, and the second hydraulic rod is also fixedly installed inside the outer shell through the clamp.

[0009] As a preferred scheme of the utility model, a first fixing seat is fixedly arranged on the outer side near the lower part of the interior of the outer shell. A contact block is sleeved and fixedly installed on the outer end of one side of the hammer head below the piston rod. A spring installed on the first fixing seat is arranged in the cavity between the contact block and the first fixing seat.

[0010] As a preferred scheme of the utility model, a first hydraulic rod is connected between the front end of the vehicle body and the left and right sides of the outer shell, and the first hydraulic rod and the outer shell are hinged through a hinge.

[0011] As a preferred solution of the present invention, a second tool compartment is provided inside the rear side of the vehicle body, and an openable compartment door is provided on the top of the second tool compartment.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, a new type of dynamic tamping machine is set up. When the dynamic tamping machine is used, the second hydraulic rod is used to drive the piston column below to move up and down, thereby driving the hammer head located on the outside of the bottom of the outer shell to reciprocate to perform compaction operations.
