Description

[Detailed description of the invention] [Field of industrial application] This invention is suitable for backfilling, resurfacing, etc. of narrow and long-distance trenches such as water pipe trenches, sewer pipes, gas pipe trenches, and communication pipe trenches. Concerning the side unloader used.

[Prior art] Conventionally, crushed stone, earth and sand, asphalt, and concrete have been used to backfill and resurface narrow and long-distance trenches such as water pipes, sewer pipes, gas pipes, and communication pipes. The materials consisting of the above materials were first unloaded from a dump truck near the ditch, and then the material was transported and leveled using a scoop or the like. Therefore, not only is work efficiency low and costs high, but there are also drawbacks such as polluting nearby roads. This kind of work causes traffic congestion, so it needs to be done quickly, but for the reasons mentioned above, the work is time-consuming and has not yielded satisfactory results.

[Object of the Invention] The present invention has been made to solve the above-mentioned drawbacks, and is capable of backfilling narrow and long-distance trenches such as water pipe trenches, sewage pipe trenches, gas pipe trenches, and communication pipe trenches; By mechanizing resurfacing, etc., the objective is to speed up work, improve efficiency, save labor, and reduce costs.

[Configuration of the Invention] The present invention provides a hopper with an open front for dumping and
It is removably attached to the rear of the car's loading platform and perpendicular to the direction of travel of the dump truck.A conveyor such as an auger conveyor or a belt conveyor is built into the lower part of the hopper, and an outlet is provided on the bottom of one end. Regarding a side unloader characterized by being provided with an open transfer gutter, in particular, the transfer gutter is slidable relative to the hopper, and the outlet of the transfer gutter is laterally outward from the width of the dump car body. protruding cage;
The above object is achieved by providing a side unloader in which the transfer gutter is tilted forward toward the loading platform.

[Embodiment] Next, a side unloader according to the present invention will be described based on an embodiment shown in the drawings. Hoppa 1 is
The front and top surfaces are open, and a wire 4 hanging from the hinge pin 3 of the rear part 2 of the dump truck is hooked to a locking part 5 protruding from the side.
By fitting the front bottom portion 6 to the rear lower part of the dump car's loading platform, the front bottom portion 6 is removably attached to the rear portion of the loading platform 2 of the dump car. This attachment of Hoppa 1 is
It is perpendicular to the direction of travel of the dump truck (direction of arrow A). The front bottom part 6 is configured to be replaceable so that the shape most suitable for the rear lower part of the dump car is selected. A transfer gutter 8 in which a conveyor 7 such as an auger conveyor or a belt conveyor is incorporated is provided at the bottom of the hopper 1 and communicates with the outlet 9 of the hopper. A take-out port 11 is formed at one end of the transfer gutter 8, and a take-out port 12 is formed on the lower surface of the take-out port 11.
is opened. The transfer gutter 8 preferably includes a slide device 10 consisting of a roller, as in this embodiment.
It is slidably provided on the hopper 1 via the hopper 1. In this way, if you come into contact with an obstacle such as a telephone pole during work, you can easily avoid it, and when you are not working, you can move the outlet 11 within the width of the hopper 1, making it more compact. This saves storage space. Further, as in this embodiment, the transfer gutter 8 is preferably provided so as to be tilted forward toward the loading platform so that it becomes approximately vertical when the loading platform is rotated during work. If the outlet portion 11 is formed to protrude laterally outward from the vehicle body width of the dump car as in this embodiment, if there is a groove to be constructed at the side edge of the road, the dump car Since it is easier to drive, it is easier to work. Reference numeral 13 denotes a support leg which is pivotally connected to the hopper 1 and can be opened and closed, and has a caster 14 at the bottom thereof, and a brake device (not shown). The supporting legs 13 support the hopper 1, the transfer gutter 8, etc. when installed, and are configured to be freely openable and closable so that the support is released during work, but they may be configured to be extendable and retractable instead of being freely openable and closable. 15 is an engine, 16 is an oil tank, 17 is a forward/reverse valve, and 18 is an oil motor.

[Operation and Example of Use] Next, an example of the use of the example machine will be explained along with its operation. To attach the side unloader according to the present invention to a dump car, after suitably backing up the dump car and fitting the front bottom part 6 of the hopper 1 to the rear lower part of the dump car's loading platform, the side unloader is attached to the dump car. The wire 4 hanging down from the hinge pin 3 of the rear part 2 of the loading platform is hooked onto a locking part 5 protruding from the side surface of the hopper 1. When fitting the front bottom part 6 of the hopper 1 to the rear lower part of the dump car's loading platform, the side unloader supported by the support legs 13 is appropriately moved by the casters 14 to make fine adjustments for installation. can be done. When the side unloader is attached to the dump truck, the supporting legs 13
is expanded and released from support of the side unloader. Next, an oil pump (not shown) built in the oil tank 16 is driven by the engine 15, and the forward/reverse valve 15 is operated manually or electrically to rotate the oil motor 18. The conveyor 7 is driven. Next, the loading platform of the dump car is rotated to cause the earth and sand loaded on the loading platform to fall into the hopper 1. The earth and sand that has fallen into the hopper 1 is dropped from the outlet 9 into the transfer gutter 8, is conveyed through the transfer gutter 8 by the conveyor 7, and falls from the outlet 12 of the outlet 11 into the trench to be constructed. It will be done.

In this way, earth and sand fall directly into the trenches that are the target of construction work, making it easy to backfill narrow and long trenches.
When resurfacing or the like, there is no need to temporarily unload earth and sand onto the road near the ditch, as is the case in the past. Therefore, the work is labor-saving and speeded up accordingly. If you come into contact with an obstacle such as a telephone pole during work, you can easily avoid the obstacle by pushing the outlet 11 and sliding the transfer gutter 8. In addition, since the transfer gutter 8 is tilted forward toward the loading platform, when the loading platform is rotated during work, it becomes almost vertical, making it easier for earth and sand to fall. Furthermore, since the outlet portion 11 is formed to protrude laterally outward from the width of the dump truck, it is easy to drive the dump truck when there is a groove to be constructed at the side edge of the road. This makes the work easier. Therefore, work can be done quickly and work efficiency is extremely high.
Moreover, the attachment of the side unloader according to the present invention to the dump car, the driving of the engine 15, and the operation of the dump car can be easily carried out by one worker as described above, and dirt and sand can be removed easily. Since the process described above is used to mechanize the dropping of the dump truck into the ditch, the backfilling and resurfacing of the ditch can be done automatically by moving the dump truck forward at a slow speed. Therefore, the work is labor-saving, and the work cost is significantly reduced compared to the conventional one (according to the applicant's experiments under the same working conditions, this example machine costs about 100% less than the conventional one) 3 times the work efficiency).

[Effects of the Invention] As described above, the side unloader according to the present invention can backfill and resurface narrow and long-distance trenches such as water pipe trenches, sewer pipe trenches, gas pipe trenches, and communication pipe trenches. etc. can be mechanized, which has the effect of speeding up work, improving efficiency, saving labor, and reducing costs.
