Description

Tree Root Crusher {The root crusher}

The present invention relates to a crushing device of the tree roots generated during civil works, and in detail, by placing the wedge-formed pressure plate on both sides to operate each pressure plate hydraulically, the tree root is split into pieces by the lateral pressure applied from the wedge. Apparatus, and relates to a device for enabling the use of waste tree roots as a firewood or in the production of sawdust.

Conventional logging is carried out during various civil works such as road works and site construction works that pass through forests, and a large amount of tree roots is generated in the process.

Logged wood has many uses, such as being used as timber after sanctions, but large tree roots are decomposed after landfilling, causing ground subsidence, which is not suitable for landfilling, and incineration consumes enormous energy for incineration. For this reason, there have been many problems in the treatment, and most of the treatment companies are dealing with methods such as leaving them to be left unsealed or put into a large number of personnel and cutting and crushing them.

Meanwhile, as a method for treating tree roots known to date, a method of shredding after cutting by using a suitable device (Korean Patent Publication No. 2001-0107895), a method of direct shredding (Korean Utility Model Publication No. 20-0272930, Korean Utility Model Publication) 20-0227265), but the shredding device for the above-described method is a wood located between the shredding roller or disc cutter by forming the shredding roller or disc cutter on the rotary shaft installed side by side on each side and rotating the respective rotary shafts in opposite directions. It is a structure that crushes and crushes the roots continuously. It has some effects on the crushing of small tree roots, but crushing of large tree roots larger than 2m in diameter is impossible or very inefficient.

That is, the shredding device has a structure in which the tree roots are continuously crushed while the two root shredding rollers or disc cutters are crushed continuously, or in the case of a large tree root, only a part of the cutter contact is cut and then a space between the cutters is cut. There was a problem that occurs no longer cutting.

Due to these problems, a method of crushing after dividing it to a predetermined size or less using a saw is being tried, but the processing efficiency is low due to the addition of a saw cutting process, and since the general tree root contains a large amount of soil or stone, etc. Another problem arises when using a saw for the saw blade is easily worn or broken.

The present invention has been devised for the purpose of presenting a tree root shredding device that can be utilized for various purposes by effectively crushing a large tree root to solve the problems of the conventional shredding device.

To this end, the present invention installs a supporting rod at the bottom of the hopper supported by the frame, and forms an opening at both symmetrical sides of the hopper so that the wedge and the pressure plate protruding into the hopper on the front of the pressure plate and the pressure plate are operated. When the pressurizer consisting of cylinders is combined, and the hydraulic pressure is applied to the pressure plate while the tree root is put into the hopper, the wedge digs into the tree root and presses it, splits the tree root into several pieces, and the split wood fragment is lowered from the base rod. We propose a tree root shredding device that is configured to be discharged.

Figure 1 shows a basic embodiment of the present invention, Figure 2 shows a planar state, the present invention is a hopper 20 for injecting the tree root, the frame 10 for supporting the hopper, and the hopper Composed of a pressurized device 30 for splitting and splitting the wood put into the inside.

The frame 10 is composed of a support 11 and a lattice frame 12 so that the hopper is positioned at a predetermined height from the ground, and the hopper 20 is a rectangular structure of upper light lower side. It is installed on the upper part of the frame to form a space for putting tree roots.

The hopper 20 has an opening 21 formed at both symmetrical sides of the lower portion, and a supporting rod 22 at the lower portion thereof.

Base rods are rods installed at the bottom of the hopper at approximately 50 cm intervals to prevent the tree roots from escaping the lower hopper and to allow the shredded tree roots to escape the lower hopper.

The opening 21 serves as an entrance and exit of the pressure plate, and serves to allow a piece of wood roots, which are bitten by some wedges, to hang on the wall of the hopper when the pressure plate is retracted after the tree roots are broken.

The pressurizing device 30 is installed on both symmetrical sides of the hopper and is a device for sculpting tree roots. The presser plate 31 is installed in the opening 21 of the hopper and the wedges are provided in a protruding form in front of the pressing plate. 32) and a hydraulic cylinder 33 coupled to the pressure plate while the head portion is supported by the frame.

The pressure plate 31 is a rectangular plate coupled to the hydraulic cylinder to advance through the opening into the hopper according to the stroke of the cylinder, thereby applying a pressure for the wedge to dig into the tree roots.

The wedge 32 is formed to protrude on the front surface of the pressure plate, the tip is pointed and the body part has a width of about 20 cm in the form of a wedge, which acts to split the tree roots in the transverse direction by the lateral pressure acting when digging the tree roots. Perform.

The wedges are formed in the pressure plate at lateral intervals of 40-60 cm, the length is formed in the range of 70-100 cm, the cross-section of the wedge can be round or square.

The side width should be at least 20 cm to facilitate tree splitting.

In addition, the wedge is formed at intervals of approximately 40-60cm in the left and right or up and down directions, it can be replaced by one wedge by increasing the height of each wedge in the vertical direction.

The wedges may be configured in a fixed form in which the left and right movements are limited on the pressure plate. In this case, the wedges formed on the front and rear pressure plates may be alternately formed in a zigzag pattern, and two rows (either in the case of increasing the height) in either the front or rear pressure plates. Two) and one row (or one) of wedges is preferably formed on the other pressing plate.

This is because if the number of wedges arranged from side to side in a state where the wedges are fixed to the platen is too large, the crushing efficiency is lowered because the left and right wedges prevent the opening of the wedge based on the central wedge.

On the other hand, the wedges can be installed to move a certain distance in the left and right direction from the pressure plate, in this case, while the roots of the wood is gradually opened by the action of the wedge, the gap between each wedge is spread to meet the lateral pressure, effectively splitting the roots Will be.

FIG. 3 shows an embodiment in which the wedge can be moved in the left and right direction, and a rectangular groove 31a in the left and right direction is formed at the wedge engagement position of the pressure plate 31, and the wedge 32 is formed to flow in the groove. After coupling, the spring 31b is coupled to the wedge under the spring force within the groove.

The structure does not resist the lateral pressure acting when the adjacent wedges dig into the tree, and moves the position in the left and right directions by the lateral pressure, so that the pressure increases and the gap between the wedges is increased in the direction of opening the tree roots. Make sure you split effectively.

In the above structure, the pressing device 30 may be formed on the front and rear sides of the hopper as shown in FIG. 1 by forming two sets of two devices installed at symmetrical positions, and as shown in FIG. 4. It can be formed on the rear side and left and right sides, and in this case, the tree roots can be split in one direction by pressing from the front and then pressed from the left and right to split it in the right direction so that the tree can be effectively crushed.

In addition, one of the pressurizing device constituting one set in the above omits the hydraulic cylinder for advancing the pressing plate back and forth as shown in Figure 5, the pressing plate is configured to be fixed to the side wall of the hopper, the wedge 32 formed on the pressing plate ) Is coupled to the flow through the through groove 31c formed in the pressure plate after connecting the respective pressure plates using the connecting rod 34 in the back of the pressure plate and then connecting the connecting rod and the pressure plate with the hydraulic cylinder (35). Can be implemented.

The wedges installed on the fixed pressure plate can be pulled in and out of the pressure plate by the hydraulic cylinder to prevent the wedges from retreating when the tree roots are inserted, and to retreat even when the tree roots are bitten by the wedges. It acts to make it possible.

The structure is configured to flow only one pressure plate and the other pressure plate is fixed to install a large hydraulic cylinder only on one side, the other side has the advantage that can be reduced in the capacity of the hydraulic unit by installing and using a small hydraulic cylinder. .

The present invention by the above configuration can be effectively used for large tree roots by dividing the tree root into several pieces by the action of the wedge formed in the front and rear or left and right pressure plate, the fragmented tree root is discharged to the lower part of the base rod After the sorting work to separate the soil and wood chips, it is used as a firewood or put into a sawdust maker and used as sawdust.

In the drawings, reference numeral 40 denotes a tree root, and 41 denotes a conveyor for discharging the crushed tree root.

The present invention by the above configuration has the advantage that can be recycled for various purposes by easily crushing the large tree roots by dividing the tree roots to the size available to use the pressure plate formed with wedges.
