Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing agent-filled water injection machine for crushing brittle objects such as rocks and concrete, for filling the crushing agent in holes previously drilled in these objects and injecting water. It is a thing.

[0002]

2. Description of the Related Art A crushing method utilizing a static crushing agent is used for crushing brittle objects such as rocks and concrete. In this method, a plurality of holes having a predetermined depth are preliminarily drilled in rock or the like to be crushed, and these holes are filled with a crushing agent containing quicklime as a main component and reacted with water. It crushes rocks, etc. When filling a crushing agent into a hole drilled in rock or the like, an impact force is often applied to the filled crushing agent for the purpose of increasing the packing density. In this case, the filling operation of the crushing agent is performed by repeating the operation of charging the crushing agent into the hole and the operation of crushing the charged crushing agent with the impacting device. The applicant has developed a crushing agent filling machine for filling a crushing agent into a hole drilled in a rock or the like in the vertical direction and has already applied for a patent (Japanese Patent Application No. 2-293742).

[0003]

DISCLOSURE OF THE INVENTION The above-mentioned invention is intended to fill a crushing agent in a hole vertically drilled in a rock or the like, and after immersing the crushing agent individually prepackaged in water,
I try to fill the holes. Therefore, the crushing agent filling machine does not have a special water injection function. If the crushing agent is immersed in water and then filled in the holes as described above, there is a problem that the reaction of the crushing agent proceeds even before the holes are filled.
However, when used under the condition that the holes are drilled in the vertical direction, the crushing agent put into the main body immediately falls into the holes, and thus has sufficient practicality. On the other hand, when the hole is drilled horizontally, if the crushing agent pre-soaked in water is put into the main body, this crushing agent does not immediately fall into the hole, and the reaction of the crushing agent proceeds in the main body, which is inconvenient. Is.

An object of the present invention is a further development of the above invention, which makes it possible to separately fill and inject water with a crushing agent into holes drilled in rocks or the like, thereby carrying out the crushing work. It is intended to provide a water injection machine filled with a crushing agent that can be carried out more safely.

[0005]

In order to solve the above-mentioned problems, a crushing agent filling water injection machine according to the present invention is a crushing agent filling water injection machine for filling a pre-drilled hole with a crushing agent and water injection. There is a cylindrical body with a crushing agent input port,
An introducing member that is provided inside the main body so as to correspond to the input port and introduces the crushing agent that has been charged into the hole, and the crushing agent that is movably provided in the main body and strikes the crushing agent A hitting member for filling the hole, a locking member provided in the main body for locking the hitting member, and a water injection member provided in the main body for injecting water into the hole, It is composed.

[0006]

According to the crushing agent filling water injection machine (hereinafter referred to as "filling machine"), the crushing agent can be filled at a high density in the holes previously drilled in rocks or the like, and water can be appropriately injected. Therefore, the reaction of the crushing agent can be started by filling the hole with the crushing agent and then injecting water. Therefore, it is possible to appropriately adjust the reaction start time of the crushing agent filled in the holes and water, and it is possible to safely perform the crushing work on rocks and the like. That is, the striking member is locked by the locking member provided on the cylindrical main body, the crushing agent is introduced from the charging opening provided on the main body, and then the locking of the striking member is released to drive the striking member. At the same time, the crushing agent can be packed at a high density by moving the crushing agent along the main body and applying a striking force to the crushing agent. Then, water can be injected into the hole filled with the crushing agent by an appropriate water injection member.

The engaging member 6 can be locked by engaging with d. The state in which the striking member 6 is locked by the locking member 8 is the standby state of the striking member 6. Further, the hitting member 6 is moved along the main body 1 by rotating the lever 8c of the locking member 8 against the biasing force of the spring to release the engagement between the locking piece 8d and the engaging piece 6e. It is possible to

The tip of the rod 6b forming the striking member 6 is formed to have a diameter slightly smaller than the inner diameter of the pipe-shaped introducing member 5. Further, a disc-shaped shield member 9 is fixed inside the main body 1 at a position corresponding to the tip of the rod 6b when the striking member 6 is in the standby state. Body 1
Even if the crushing agent filled in the hole suddenly starts the reaction, the influence of this reaction is not transmitted to the operating side by providing the shielding member 9 on the.

A water injection member 10 is attached to a tip pipe 5a constituting the introduction member 5. The water injection member 10 is formed of a ring-shaped member having a plurality of nozzles formed therein and projecting a supply port 10a connected to the hose 11.

But hole B
If the operator holds the weight of the filling machine A when the holes are horizontally drilled, the workability may be deteriorated. Therefore, in this embodiment, the weight of the filling machine A is reduced by attaching the main body 1 to the leg member 15 via the bracket 14.
It is configured to be supported by.

Next, a hole B drilled horizontally in a rock or the like.
The procedure for filling the crushing agent and injecting water with the filling machine A configured as above will be described with reference to FIG. When the hole B is drilled in the horizontal direction, the filling machine A is supported by attaching the tripod 15 as a leg member to the bracket 14. Then, by adjusting the height and posture of the tripod 15, the filling machine A is aligned with the axis of the hole B and the introduction member 5 is inserted.
Insert the tip pipe 5a of the above into the hole B. Then the hose 12
The valve 13 and the water injection tank 16 are connected via the, and the air compressor 18 and the valve 6f provided on the handle 6c are connected via the hose 17. Further, by connecting the water injection tank 16 and the air compressor 18 with a hose 19, a predetermined pressure is applied to the water in the water injection tank 16.

The rod 6b advances as the chipper 6a advances, whereby it is possible to fill the hole B with the crushing agent introduced into the introducing member 5 and to impart a striking force to increase the packing density. The depth when the rod 6b reaches the forward limit is detected by the positional relationship between the detection bar 6d attached to the handle 6c and the filling position gauge 7. When the hole B is filled with a predetermined amount of the crushing agent by repeating the above operation, the chipper 6a is retracted to maintain the standby state, and the valve 13 provided in the main body 1 is opened, whereby Water injection member 10 to tip member 5 of introduction member 5
Water is poured into hole B via a. By this water injection, the reaction between the crushing agent filled in the hole B and water starts. Therefore, by appropriately setting the water injection timing for the holes filled with the crushing agent, it is possible to set the reaction start time of the crushing agent and water to a desired time.

In the embodiment described above, the bracket 14 is attached to the main body 1.
And the leg member 15 is attached to the bracket 14 so that the weight of the filling machine A can be supported.
Therefore, in the present embodiment, it is not necessary for the worker to hold the filling machine A when performing the filling work of the crushing agent into the hole and the water injection work, and it is possible to reduce the labor of the worker and improve the workability. Is.
