Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the upper and lower plates 11 are largely divided into a body 10 connected to the support 12 and a cutter 20 connected to the upper plate 11a.

The upper plate 11a is formed with a guide rail 23 in which the coupling moving part 21 coupled to the upper portion of the hydraulic cylinder 20a is movable in a linear direction.

As shown in FIG. 2, the guide rail 23 has a coupling protrusion 23b corresponding to the coupling protrusion 23a such that the coupling protrusion 23a formed on the coupling moving part 21 is slidable. It is formed to face one side.

The coupling moving part 21 is formed with a coupling protrusion 23a which is coupled to the guide rail 23 and moves to one side, and is coupled to the hydraulic cylinder 20a on the other side.

The hydraulic cylinder 20a is coupled to the coupling moving part 21 which can be linearly moved in both directions to the upper end, and is coupled to the cutter 20b which cuts firewood by receiving an impact force at the lower end and adjusts the hydraulic pressure on the side of the hydraulic cylinder. The regulator 22 which operates 20a is provided.

Here, the cutter 20b coupled to the hydraulic cylinder 20a is preferably installed such that the cutter 20b vertically hits the surface of the firewood so that the stress applied to the firewood is maximized.

In addition, the cutter (20b) receives the impact force from the hydraulic cylinder (20a) coupled to the upper cutting the firewood, the area of the area hitting the firewood so that the breaking force by the stress generated at this time is increased as much as possible It is preferred to be formed with minimal.

On the other hand, the lower plate (11a) is preferably provided with a seating groove 19 in which the firewood can be seated in the center along the traveling direction of the guide rail 23 so that the firewood is not offset to the left and right. .

In addition, when the firewood and the cutter 20b coupled to the hydraulic cylinder 20a collide with each other in the lower plate 11b, the momentum changes rapidly, so that the time that acts between the objects is short as long as the momentum does not change large. Force is at work. Therefore, the size of the lower plate 11b preferably has an appropriate area to disperse the vibration caused by the movement generated when the carter 20b cuts the firewood to the maximum.

In another embodiment, as shown in Figure 3, the lower plate (11b) is a fixed pin 17 for fixing the firewood is installed in the hook portion 16 and the hydraulic cylinder to be easily fixed to the firewood ( It is preferable that a plurality of hook portions 16 are provided along the traveling direction of 20a).

Here, the fixing pin 17, the head portion (17a) is formed on the upper portion, the lower portion of the striking portion (17b) is connected through the connecting rod (17c) and the spring (18) including the connecting rod (17c) inside ) Is interposed between the head 17a and the striking part 17b.

In addition, when the spring 18 mounted on the fixing pin 17 tensions the head 17a, the spring 18 is compressed and the firewood is placed in a predetermined position, and then the tension of the head 17a is increased. When released, it is configured to interpose between the striking portion 17b and the hook portion 16 so that the firewood is fixed by the elastic force of the spring 18.

In this way, the spring 18, which is an elastic body, is compressed by pulling the head portion 17a of the fixing pin 17 so that deformation occurs, and at the same time, a deformation force is generated to return the deformed state to its original state. Thereafter, the head 17a is released so that the striking portion 17b is fixed to the firewood due to the restoring force for restoring the deformation force inside the spring 18.

As shown in Figure 4, in another embodiment, the lower plate (11b), the fixing plate 13 is installed on one side to fix the firewood at both ends to support one end of the firewood and the fixing plate 13 on the other side A compression plate 15 connected to the compression cylinder 14 is installed so as to compress the firewood supported by the other end to be fixed.

Here, the pressing plate 15 connected to the compression cylinder 14 is preferably installed in the direction of fixing the firewood along the guide groove 19.

Referring to the operation of the operation of the present invention made of such a configuration as follows.

First, the firewood is placed in the proper place of the lower plate (11b).

At this time, the firewood may be seated in the seating groove 19 formed in the lower plate (11b), in another embodiment hook portion formed along the seating groove 19 of the lower plate (11b) to fix the seated firewood. It is fixed to the fixing pin (17) of the 16, or one end of the firewood is fixed to the fixing plate 13 installed on one side of the lower plate (11b) and the other end is fixed to the pressing plate 15 of the compression cylinder (14) You may be.

Here, a spring 18 is used to fix the firewood with the fixing pin 17, the spring 18 is interposed between the hook portion 16 and the striking portion 17b to the head portion 17a. Pulling the spring 18 deforms and compresses between the hook portion 16 and the striking portion 17b and stores it as potential energy, because the deformation force to return to its original state when it is deformed by external force is generated inside. Subsequently, when the tension of the head 17a is abruptly removed from the spring 18 which is the deformed elastic body, the potential energy of the deformed elastic body is released at once to fix the firewood.

In another embodiment, one end of the firewood is supported by the fixing plate 13 installed on one side of the lower plate 11b, and the other end of the firewood on which the fixing plate 13 is supported by operating the compression cylinder 14 installed on the other side. This is fixed by pressing the compression plate 15 connected to the compression cylinder (14).

As such, after the firewood is fixed, the sliding movement unit 21 coupled to the hydraulic cylinder 20a is slidably moved along the guide rails 23 to an appropriate position, and the hydraulic cylinder 20a is attached to the side of the hydraulic cylinder 20a. When the regulator 22 is operated, the carter 20b coupled to the hydraulic cylinder 20a is operated to hit the firewood, so that the firewood is split into two.

Here, in the case of firewood that is hard to be split by a single hit of the carter 20b, the coupling moving part 21 may be moved and re-hit to cut even when the firewood is long.
