Conventionally, in the case of a conventional waste wallet processing apparatus, 15 to 20 waste drums are charged into the compression chamber, and the first cylinder compressors, which are operated by the power of the oil pressure unit, are pressed downward to compress the waste drums to be flatly compressed. A second cylinder compressor driven by the unit pressed sideways to compress the waste drums laterally and the compressed waste drum was moved to the rear end by a conveyor that automatically rotates by the drive motor.

However, since the conventional waste-tube compacting system compresses a plurality of waste drums at a time, not only an expensive high-output hydraulic unit is used but also each cylinder compressor for down-compression and lateral compression is used and a waste- There is a problem in that the cost of constructing the facility is excessively increased. In addition, as each device is constructed, the equipment is enlarged and it is not easy to secure a space for constructing the compression facility. Since the movement is restricted, the waste drums which are not subjected to the compression process must be transferred to the place where the compression facility is located. There has been a problem in that it occurs.

First, the compression chamber 110 is a chamber member for providing a space in which the waste drum 20 can be compressed, and an arm engagement portion 113 detachably mounted on an end portion of the arm 11 is provided on an upper or peripheral surface And a cylindrical compression space 115 for accommodating the upright waste drum 20 is formed to be opened downward. As shown in FIGS. 3 and 4, the compression chamber 110 has a downwardly opened circular tube shape and includes a lower body 111 having the compression space 115 formed therein, and an arm engagement portion 113 formed at an upper portion thereof And the lower part is composed of an upper body 112 mounted on the lower body 111.

The arm coupling portion 113 includes a plurality of support links 113 to be inserted into and supported by engagement grooves (not shown) formed in the ends of the arm 11 of the conventional excavator 10, And a bracket for fixing the position of the bracket. Also, the compression chamber 110 may be made of a rigid steel material or a high strength composite plastic material, and the lower body 111 and the upper body 112 may be coupled to each other by screwing or welding.

1 and 2, a monitoring hole 116 is formed on the periphery of the compression chamber 110 at a position facing the driver's seat 13 of the excavator 10 and laterally opened. As shown in FIG. 1 and FIG. 2, (See the dashed arrows in Fig. 1) in the state in which the compression chamber 110 is mounted on the excavator 10, the pressure plate portion 130 is in a state of compressing the waste drum 20, It is preferable to be provided so as to easily recognize the normal operation state of the cylinder 120.

The driving cylinder 120 is a driving means for providing a driving force required to pressurize the waste drum 20 so as to compress the waste water into the compression chamber 110 such that the rod 121 is inserted through the compression space 115 downwardly. And the rod 121 is moved up and down in the compression space 115 in accordance with the supplied fluid pressure.

The driving cylinder 120 is rigidly fixed to the upper portion of the lower body 111 through a flange 124 formed around the lower end of the lower body 111 and fixed to the lower body 111, 121 to move vertically within the compression space 115. In addition, the driving cylinder 120 is provided with ports 122 and 123 for injecting and recovering fluid pressure from the outside. In addition, although the drive cylinder 120 may be driven by receiving a fluid pressure from a separate fluid supply means such as a hydraulic or pneumatic pressure, as shown in FIGS. 1 and 2, the fluid pressure is supplied from the excavator 10 It is preferable that it is driven.

To this end, one side is connected to the drive cylinder 120 and the other side is connected to a cable connector 12, which is supplied with fluid from the fluid supply line of the excavator 10 on the arm 11, And a pressure cable 140 for supplying the driving cable 120 to the driving cylinder 120. The cable connector 12 supplies fluid pressure for driving a bucket (not shown) mounted on the end of the arm 11 to the excavator 10 to a separate mounting equipment mounted in place of the bucket .

Further, since the fluid supplied to the fluid supply line is supplied and controlled by the driver in the driver's seat of the excavator 10, a fluid supply device necessary for driving the drive cylinder 120 or a separate control and steering means for controlling the fluid supply device The structure of the compression device can be further simplified and the maintenance cost can be reduced. In addition, when the excavator 10 is driven by hydraulic pressure, the driving cylinder 120 uses a hydraulic cylinder, and in the case of a driving system using pneumatic pressure, a pneumatic cylinder is used.

3 and 4, the pressure plate portion 130 is formed in a disk shape and horizontally disposed in the compression space 115, and the pressure plate portion 130 is formed as a pressure member for directly pressing and compressing the waste drum 20, And is pressed downward so that the waste drum 20 accommodated in the compression space 115 is compressed while being coupled to the rod 121 and moving up and down together.

The fixing plate 131 is formed at the center of the pressure plate 130 so as to protrude downward and press down the upper center of the waste drum 20 accommodated in the compression space 115 Do. It is possible to effectively prevent the waste drum 20 from being compressed in a state in which the waste drum 20 is biased in the compression space 115 by the fixed fixing portion 131. [ The upper center of the waste drum 20 is pressed by the fixed needle 131 before the upper edge of the waste drum 20 is pressed by the flat bottom surface of the pressure plate 130, The upper end of the side wall is inclined toward the center, so that the waste drum 20 can be compressed with less force as compared with the case where the side wall of the waste drum 20 is downwardly pressed.

Next, the operation principle of the compression apparatus 100 according to the preferred embodiment of the present invention will be described. First, as shown in Fig. 6, a first place (a) in which a waste drum 20a to be compressed is loaded, a second place (b) in which the waste drum 20 is compressed by the compression apparatus 100, When the arm portion 11 3 of the excavator 10 is connected to the female coupling portion 113 of the compression apparatus 100 in a state where the third place C 1 on which the treated waste drum 20 b is loaded is separated from each other And the excavator 10 is moved to the compression processing place (b).

Thereafter, the waste drum 20a loaded in the first location (a) is transported to the second location (b) using the arm 11 of the excavator 10 and the compression chamber 110. The arm 11 is controlled or compressed so that the end of the arm 11 is moved toward the second position b in a state in which the waste drum 20a is inserted into the compression space 115 of the compression chamber 110, It is possible to convey each waste drum 20a by controlling the arm 11 so that the side of the chamber 110 pushes the waste drum 20a. At this time, it is preferable that each of the waste drums 20a is maintained in an upright state so that the carried waste drum 20a is easily inserted into the compression space 115 of the compression chamber 110.

4, the arm 11 is controlled so that the compression chamber 110 is positioned upright at the upper position of the transported drum 20, and the waste drum 20 And the fluid 121 is supplied to the drive cylinder 120 through the pressure cable 140 as shown in Figure 5 so that the load 121 is compressed in the compression space 115 ). As a result, the pressure plate portion 130 coupled to the end of the rod 121 presses down the upper portion of the waste drum 20, and the waste drum 20 is compressed while being restrained in the compression space 115.

After the waste drum 20 is compressed and the end of the arm 11 is moved to the third position C, the fluid pressure supplied to the driving cylinder 120 is recovered, The arm 11 is lifted so that the compression chamber 110 is lifted in the compression space 115 and the compression chamber 110 is spaced from the ground so that the compressed waste drum 20b is loaded in the third place C . If the waste drum 20 is transported from the first location A to the second location B by pushing the compression chamber 110 while the bottom of the waste drum 20 is seated on the ground, The friction between the floor surface of the floor and the ground may cause scratches or breakage in the case of a solid ground, and in the case of a ground floor, the ground is lost, and such a transportation may be repeatedly carried out.

Accordingly, the compression apparatus 100 according to the preferred embodiment of the present invention can be provided so that the waste drum 20 accommodated in the compression space 115 can be supported so as not to fall by its own weight and lifted up from the ground . 7 and 8, an inner wall of the compression chamber 110 is provided with a plurality (not shown) for pressing the sides of the waste drum 20 accommodated in mutually symmetrical positions with respect to the center of the compression space 115 The pressing projections 117 are protruded to lift the waste drum 20 accommodated in the compression space 115 opened downward by using the frictional force between the pressing protrusion 117 and the waste drum 20, So that the waste drum 20 can be easily transported without being damaged or damaged.

 Since the projection insertion groove 132 is formed at the position corresponding to the pressing projection 117 on the periphery of the pressing plate part 130 so that the pressing plate part 130 and the pressing projection 117 move up and down It is possible to prevent mutual contact and damage.

Unlike the conventional compression equipment in which a plurality of waste drums are subjected to compression processing at the same time and an expensive high-output oil pressure unit is required by the respective constitutions and functions of the compression apparatus 100 according to the preferred embodiment of the present invention, The waste drum 20 is individually compressed (compressed) by using the compression chamber 110 in which the compression space 115 for accommodating the compression chamber 20 is formed and the pressure plate portion 130 which moves up and down by the driving cylinder 120 in the compression chamber 110. [ It is possible to perform the compression processing with the low-output low-output driving cylinder 120, so that the cost for constructing the compression facility can be drastically reduced.

The compression space 115 is formed in a cylindrical shape corresponding to the erected waste drum 20 so that the waste drum 20 is compressed by the pressing plate portion 130 downward to compress the compression space 115 So that a separate compression device such as a second cylinder compressor for pressing the side of the waste drum in the conventional compression facility is unnecessary, so that the construction cost of the compression facility can be further reduced.

The waste drum 20a to be subjected to the compression process is mounted on the arm 11 of the excavator 10 having a wide work area at the stopped position and movable using the arm 11 and the compression chamber 110, It is possible to carry the waste water from the loaded place (a) to the compression treatment place (b) and to the place (c) where the waste drum (20b) The conveying means such as a conveyor for conveying the waste drum to be compression-processed to the inside of the compression chamber or for conveying the waste drum, which is compressed in the compression chamber, to the rear end is unnecessary in the compression facility, so that the construction cost of the compression facility can be further reduced.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge.
