The present invention relates to a device for transporting collected waste to a large container for transport, and more particularly, to a garbage lifting device that can be used in combination with a waste compaction apparatus or directly loaded with a waste transport container.

In general, household waste is collected in a garbage collection container or other garbage collection container high enough for ordinary people to easily put the garbage in, and then transported to a large transport container and transported to a garbage disposal site. .

However, when moving garbage in this way, a large amount of garbage cannot be moved directly by people, so conventionally, for example, by using an aggregate operation mechanism provided at the front end of a hydraulic boom or by using a fork lift. Garbage collection containers have been adopted, such as picking up garbage containers and pouring them upside down on large containers, or by lifting up dump trucks loaded on trucks.

However, most of these conventional waste storage devices are required to be installed in a separate vehicle, not a waste transportation vehicle, in consideration of the power and mobility required for operation. It becomes a problem.

Equipment such as fork lifts, in particular, are not only classified as heavy equipment but are also very expensive, making it a disadvantage to employ them.

The present invention has been devised to solve the above problems, it can be installed directly in the crimping device or conveying container that can be easily transported to transport the waste without the need for a separate vehicle to install the device The purpose of the present invention is to provide a garbage lifting device that is made cheap and easy to move.

The present invention for achieving the above object, the waste which extends inclined from the ground to the upper side of the large container for transport and pours out from the small container for collection at the lower end of the inclined plate having a garbage drop on the bottom surface of the top A hopper for receiving and temporarily storing the hopper is installed, and one lifting arm is disposed at each of the edges of the inclined plate, connected to each other by a support shaft, and is folded and folded inward by a link mechanism installed therein. On both sides of the inclined plate, a lifting arm elevating mechanism for driving the lifting arm along the inclined plate while being driven by a hydraulic motor and controlling the relaxation operation of the lifting arm is installed.

Therefore, if the pour is poured into the hopper installed at the lower end of the inclined plate and then the lifting arm is lowered to the extended state, the lifting arms are deflected along the circular guide grooves provided at the bottom of the inclined plate, so as to grab the garbage inside the hopper. In this case, both chain mechanisms actuate to lock the damaged lifting arm and pull the lifting arm upwards so that the rubbish attracted to the lifting arm falls down through the drop opening provided at the upper end of the inclined plate. Garbage accumulates in the transport container located below the drop hole.

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

And a slanted plate 2 which is hinged to the waste compaction apparatus B via a link 10 described later and which extends obliquely to the upper side of the large container C for transporting the waste, the slanted plate 2 having While the waste dropping port 1 is provided on the bottom of the upper end, a hopper 3 for temporarily storing the waste poured out from a small container for waste collection (not shown) is installed, and the slope plate 2 A pair of lifting arms 7 are arranged at both edges and are connected to each other by supporting shafts 4 crossing the inclined plate frame 8 of the inclined plate 2 and installed therein. The lifting mechanism is provided with one lifting arm lifting mechanism 9 on each side of each of the inclined plates 2, while the link mechanism 5 and the plurality of cylinders 6 are recessed and extended inward. It is driven by the hydraulic motor 25 installed at the top to lift and lift the lifting arm 7 along the inclined plate 2 and to operate the link mechanism 5 to control the relaxation operation of the lifting arm 7. It is.

Here, the inclined plate 2 is installed to be inclined by the plurality of links 10 and the hydraulic cylinder 11 to the waste compaction apparatus B, as shown in FIG. When not in use as shown in the illustrated position by operating the hydraulic cylinder (11) it is to be positioned horizontally on the top of the waste compaction apparatus (B) shown in the dotted line.

On the other hand, the embodiment of FIG. 1 is a case in which the garbage lifting device is installed in the waste compaction apparatus (B), or a support means such as a separate pedestal or a supporting leg to directly inject waste into the large container (C) for transporting garbage. Of course, if the inclined plate (2) is supported by a separate pedestal or a support leg, as shown in the example shown in FIG. The container C may be loaded or directly transferred to the container C for transfer.

The hopper 3 is fixedly attached to a predetermined shape and height along the lower edge of the inclined plate 2 to temporarily store the waste that is poured from the outside, so that the waste can be temporarily stored. The size of the container should be approximately enough to hold 2.5 tons of garbage, which is the capacity of the garbage collection container. have.

Meanwhile, as shown in FIG. 2, the lifting arms 7 are arranged in pairs in the pair of inner edge slant plate frames 8 of the slant plate 2 to cross the slant plate 8. It is supported on both sides of the support shaft 4 which is provided to be stretched together so as to work together. Here, the pair of lifting arms 7 are three split arms 13, 14, and 15 hingedly connected to each other by a plurality of hinges 12a and 12b, respectively, as shown in FIG. The first and second split arms 13 and 14 of the split arms 13, 14 and 15 are formed of links 10a and 10b formed of cylinders 6 and 6 'having inner springs 16 and 17, respectively. The split arms 13, 14, and 15 are pivoted about the hinges 12a and 12b to the support points, and are then opened and opened.

That is, the cylinder 6 of the first link 10a is installed on the first split arm 13 so as to pivot about the bracket 18, and the cylinder head is mounted on the second split arm 14. It is also connected to pivot through the bracket 19, the second link (10b) is a second split arm (14) via a bracket (20) whose cylinder (6 ') is connected to the hinge (12a) In addition, the cylinder head is connected to the third split arm 15 via a bracket (not shown).

A support cam 21 pivoting together with the hinge 12a is fixedly attached to the hinge 12a pivotally connecting the first split arm 13 and the second split arm 14. 6, 6 ') is contracted to open the entire lifting arm (7) by pushing the lower end of the spring 16 of the first link (10a) upwards so that the lifting arm (7) is in a straight state, When the lifting arm 7 is retracted, the second split arm 15 connected to the lower end by the extension of the cylinder 6 'of the second link 10b is rotated together with the hinge 12a. Retract inward with the center.

In practice, however, when the devices of the present invention operate, they operate in the reverse order rather than the same order.

That is, the lifting arm 7 which is opened in a straight state is mediated by the support shaft 4 by the second chain 33 in accordance with the operation of the lifting arm lifting mechanism 9 shown in FIG. In the bottom of the inclined plate 2, the third divided arm 15, which is the bottommost portion, is dotted along the guide groove 22 formed on the inner surface of the semicircular portion 8 ', which is the lower end of the inclined plate frame. It is guided to the state shown in the rotation is rotated about the hinge (12b), the second link (10b) is pulled in accordance with the displacement of the vertical straight distance of the third split arm (15) rotated in this way the second split arm ( 14 rotates inward about the hinge 12a, and the rotation of the second split arm 14 pulls the first link 10a connected to the first split arm 13 again. The support cam 21 is supported by the lower side of the spring 16 installed in the one link 10a so that the The spring 16 is compressed so that the entire lifting arm 7 is bent inward.

Therefore, the lifting arm 7 is bent in accordance with the lowering of the lifting arm lifting mechanism 9 to enclose the garbage, but at the same time the state of wrapping the garbage by the action of the hydraulic cylinders 6 and 6 '. It can be maintained until the operation is opened by a separate operation.

After the lifting arm 7 is brought to the state indicated by the dotted line in FIG. 2 in this manner, the first arm is positioned at the rear end of the first split arm 13, which is the rear end of the lifting arm 7. The lock cam 23 arranged to selectively contact and support the upper end of 10a) is in contact with the upper end of the first link 10a which is lowered to overcome the elastic force of the spring 16, and thus the first link 10a. By locking the movement of the back side, the lifting arm 7 can be held in a recessed state inward, and in this state is lifted upward by the lifting arm lifting mechanism 9 into the hopper 3 The trash contained in the trash is lifted up to the trash drop hole (1).

Here, the lock cam 23 is connected to both of the lifting arms 7, and is also connected to the lifting arm lift mechanism 9, respectively, on both sides of the support shaft 4 to receive the rotational force and the driving force. Fixed to each other and rotated at a predetermined angle in accordance with the rotation operation of the support shaft 4 to contact or separate the rear end of the first link 10a so as to look or release the movement in the retraction direction of the first link 10a. It is supposed to play a role.

In addition, a support cam 24 supporting the spring 17 of the second link 10b is installed below the second link 10b to support the spring 16 of the first link 10a. When the lifting arm 7 together with the support cam 21 is straightened, the second and third split arms 14 and 15 are straightened by the resilience force of the two springs 16 and 17 compressed. To be done. In other words, the support cam 24 is fixedly connected to a predetermined position of the lower end of the second split arm 14 or the second hinge 12b to rotate together with the third split arm 15 with respect to the second split arm 14. When it is bent, it is adapted to support the spring 17 of the second link 10b.

On the other hand, the lifting arm lifting mechanism 9 is provided across the frame 8 of the inclined plate 2, as shown in FIGS. 2 and 4, to support both lifting arms 7. It is connected to an extension projecting out of the extension of both frames 8 of the shaft 4, and is configured to simultaneously lift both lifting arms 7 together with the support shaft 4, which is a function of the inclined plate 2. The driving force of the hydraulic motor 25 installed at the upper end is passed through the drive sprocket 26 provided at the drive shaft of the motor 25 and the driven sprocket 29 provided at the first chain 27 and the intermediate rotary shaft 28. The driving force transmitted to the intermediate rotary shaft 28 and then transmitted to the rotary shaft 28 is the lower end of the driving sprocket 30 and the inclined plate 2 provided outside the driven sprocket 29 of the rotary shaft 28. To rotate the second chain 33 across the driven sprocket 32 of the rotating shaft 31 in an endless orbit manner. It has a structure.

And while the lower part of the said 2nd chain 33 hangs over the half-moon-shaped rotation lock cam 34 fixedly installed on the outer extension part of the support shaft 4 which connects the both lifting arms 7, this rotation lock A part of the second chain 33 spanning the cam 34 is caught by the lock member 35 of the rotation lock cam 34.

Therefore, when the hydraulic motor 25 is started, the intermediate rotary shaft 28 that receives the rotational force through the first chain 27 rotates, and accordingly, the outer drive sprocket 30 and the lower rotary shaft 31 are rotated. The second chain 33 over the driven sprocket 32 installed in the rotation is to be rotated, at this time a portion over the rotation lock cam 34 of the second chain 33 is caught by the lock member 35 Because of the structure, the initial rotational driving force of the second chain 33 moves together with the support shaft 4 until the pivot lock cam 34 moves in the direction of the arrow 36 to the position indicated by the dotted line in FIG. Only the rotation lock cam 34 and the support shaft 4 are rotated without moving the entire second chain 33.

Subsequently, when the second chain 33 is pulled in the rotational direction by the lock member 35 to the extent that the rotation lock cam 34 can no longer rotate, the second chain 33 via the rotation lock cam 34. The support shaft (4) connected to the support shaft (4) is moved up and down in the arrow direction (37) in accordance with the movement of the second chain (33), the support shaft (4) in accordance with the lifting movement of the support shaft (4) Both lifting arms 7 which are connected together are moved up and down.

The waste lifting device of the present invention configured as described above, when the hydraulic motor 25 is operated by pouring the waste which has been established in the waste collection container into the hopper 3 in a state arranged as shown in FIG. 1, The second chain 33 lifts and lifts the lifting arm 7 while moving forward and reverse along the arrow 37. At this time, when the lifting arm 7 descends downward, the respective split arms 13, 14 and 15 And the lifting arms 7 are easily penetrated into the outside of the garbage by being lowered straight by the links 10a and 10b and the springs 16 and 17 installed therein. When 7) continues to be lowered, the guide groove 22 formed in the frame 8 of the inclined plate 2 is folded and bent in the form as shown by the dotted line in FIG. 1, and thus the lifting arm 7 This completely bent garbage If the lifting arm 7 is pulled in, the hydraulic arm 25 is driven in the opposite direction so that the rotation direction of the second chain 33 is changed so that the lifting arm 7 rises upward.

At this time, when the rotation direction of the second chain 33 is changed, the lock cam 23 fixed to the support shaft 4 is rotated while the support shaft 4 rotates together with the rotation lock cam 34. As the first link 10a pushes and locks the upper end portion, the first, second, and third split arms 13, 14, and 15 are bent to rise upward while maintaining the state in which they are narrowed inward.

That is, since the movement of the first link 10a is looked at by the lock cam 23, the second link 10b and the second and third split arms 14 and 15 are locked as they are bent. As a result, the entire lifting arm 7 is bent to maintain the state of receiving the garbage.

Thus, the waste pulled upward by the lifting arm 7 falls to the waste conveying container or the pressing device disposed below through the waste dropping hole 1 provided at the upper end of the inclined plate 2.

Next, when the rotation direction of the second chain 33 is changed to lower the lifting arm 7 again, the support shaft 4 is reversely rotated by a predetermined angle by the rotation lock cam 34 and the lock member 35. By doing so, the lock cam 23 locking the first link 10a is released from the upper end surface of the first link 10a to release the locked state of the lifting arm 7 which is locked in a bent state. As a result, the springs 16 and 17 are straightened by the restoring force and the self-weight so that they are straight and can be easily dug into the garbage.

As described above, according to the waste lifting device of the present invention, a separate place such as a garbage dump is not required, and the waste can be directly transported to a large transport container or a pressing device in a narrow place, and the waste can be easily moved to a required place. It can be moved efficiently, and there is an advantage such as not needing a separate vehicle for the waste conveying device.
