Description

[Detailed Description of the Invention] Industrial Application Field of the Invention The present invention scrapes off cut soil, earth and sand generated when excavating the ground, debris accumulated on the ground, snow during snow removal (hereinafter simply referred to as earth and sand, etc.). The present invention relates to a loader for loading a carrier such as a truck.

Conventional technology Excavators, bulldozers, etc. are often used as loaders for earth and sand, but in addition to this, power shovels, drag lines, backhoes, etc. that are mainly used for excavation are also used to excavate the ground. The generated soil is loaded on dump trucks.

Problems to be solved by the invention Any conventional loading machine is loaded by grasping or scooping up the earth and sand excavated by a bucket and turning it to the side or rear and discharging it to the carrier. However, there is a process of grasping or scooping earth and sand etc. with a bucket before loading, a process of turning the bucket sideways or backward, a process of discharging to a transport vehicle, a process of returning the bucket, etc. Therefore, it cannot be used on a narrow road in an urban area because it can load only the capacity of the bucket and needs a space for turning the bucket on the side of the loader.

In order to solve the above problems, the present applicant has previously passed the conveyor through the center of the traveling vehicle with the front down, scraped up to the end of the conveyor with a bucket, and carried the scooped earth and sand on the conveyor, and convey the conveyor. We proposed a loader for loading a truck that stands by at the rear end.

According to this loader, you can pick up sediment with a bucket and carry it to the end of the conveyor, or just scrape the sediment up to the end of the conveyor to load it into the transport vehicle, and the boom can move from side to rear as before. Since there is no turning process or returning process, loading work becomes faster, work efficiency is improved, and if there is enough space for a loader, it can be used in a narrow space, but it requires a conveyor and also for mounting a conveyor. The car body must be changed to a special structure.

The present invention is an improvement of the above-mentioned loading machine so that the sand or the like can be conveyed by using wheels or crawlers.

The loader of the present invention is an endless belt or crawler of a certain width that is hung on both wheels of a traveling vehicle, a lifting means for lifting the traveling vehicle and lifting the endless belt or crawler from the ground, and each endless belt or crawler. It consists of an enclosure that surrounds the upper side of the crawler from both sides, a hopper that is connected to the front end of the endless belt or the upper side of the crawler, and a bucket that is installed at the tip of the boom that can bend and stretch. The conveyor is detachably connected.

Action When loading earth and sand etc. on a transport vehicle, lift the traveling vehicle by lifting means such as outriggers provided at the front, rear, left and right of the traveling vehicle, and if the traveling vehicle is a wheel type, use endless belts of a certain width on the wheels on both sides of the traveling vehicle. Hang Then, a conveyor is connected to the rear part of the endless belt or crawler, and the carrier of the carrier is advanced below the rear part of the conveyor. After that, when the wheel or crawler is driven, the boom is bent and the earth and sand scooped by the bucket is put into the hopper.The earth and sand is transferred by the endless belt or crawler hung on the wheel and then transferred to the conveyor. It is loaded onto the carrier bed.

The hopper may be skirt shaped so that the tip reaches the ground. In this case, scrape the sand and sand scraped with the bucket along the hopper, bring it to the conveyor end or allow the hopper to be erected, and scrape the hopper with the bucket to raise the hopper to bring the sand and sand to the conveyor end. Try to pour.

The hopper may be separately provided for the endless belts or crawlers on both sides of the traveling vehicle, but is preferably shared. In the case of common use, a separating band is provided in the center to distribute the earth and sand or the like to the left or right, or a distribution plate that distributes the earth and sand or the like to either the left or the right is provided.

The upper surface of the endless belt or crawler is preferably horizontal or almost horizontal. This is for the following reasons.

The same can be said for the case where the conveyor is passed through the traveling vehicle with the conveyor lowered to the front, but the vehicle width cannot be set so much in consideration of traveling in urban areas, while the vehicle height is adjusted with the conveyor lowered to the rear. If the cargo bed of the carrier is allowed to enter and there is sufficient space between the car body above the conveyor and the conveyor so as not to hinder the transportation of earth and sand, it tends to be high and the center of gravity tends to be high. When the vehicle is transported to and connected to an inclined conveyor, the vehicle height can be lowered and the center of gravity can be lowered.

Embodiment FIG. 1 shows a wheel type loader, in which a rubber belt 3 having a constant width is wound around each of wheels 2 on both sides of a vehicle body 1, and an upper side surface of each rubber belt 3 is shown in FIG. Thus, the enclosures 4 are provided on the left and right. A hopper 5 is attached to the front end of the hopper 5, and a separation band 6 is provided in the center of the hopper 5 so that the earth and sand put into the hopper 5 can be distributed to the left and right rubber belts 3.

Outriggers 7 are attached to the four corners of the vehicle body 1 so that the vehicle body 1 is lifted to float the rubber belt 3 above the ground, and the wheels 2 spin idle.

A bucket 9 is attached to the tip of a bendable boom 8 which is pivotally supported by the vehicle body 1 so as to be capable of turning and being depressed.
The bending and extension of the bucket 9 allows the excavation, the scooping of earth and sand, the scraping, and the like.

This loader is configured as described above, and when loading earth and sand etc., the vehicle body 1 is lifted by the outrigger 7,
After the rubber belt is floated above the ground, the front end of the conveyor 11 which falls forward is applied to the rear end of the rubber belt 3, and the battery of the vehicle body 1 is circulated and driven. Then, the loading platform of the dump truck 12 is advanced below the rear part of the conveyor 11. After that, the wheel 2 is rotationally driven to circulate the rubber belt 3. Then, the boom 8 is bent and stretched by operating the lever in the driver's seat, and the bucket 9 is rotated to put the scooped earth and sand into the hopper 5. The loaded earth and sand is conveyed rearward as the rubber belt 3 moves, and is transferred to the conveyor 11 and dropped on the bed of the dump truck 12.

In the above-mentioned embodiment, the earth and sand scooped by the bucket 9 is put into the hopper 5, but in another embodiment, the hopper can be erected and has a skirt shape. Is pushed down, and with its tip attached to the ground, it is scraped by a bucket to scrape dirt and sand up to the end of the rubber belt.

In still another embodiment, when the sand and the like are scraped with a bucket, the hopper is raised and poured into the end of the rubber belt.

Further, in the above-mentioned embodiment, the earth and sand put into the hopper 5 is distributed to the left and right rubber belts 3 by the separation belt 6, but in another embodiment, a distribution plate is provided so that the earth and sand and the like are contained in only one rubber belt. To be supplied to.
In this case, the distribution plate is preferably arranged so that its direction can be switched so that the supply of earth and sand or the like can be switched to either of the left and right rubber belts.

Although the above embodiment relates to a wheel type loader, a crawler type loader can be similarly configured. In this case, the crawler may be made of rubber or steel.

Effect of the Invention The present invention is configured as described above and has the following effects.

In the loading machine according to claim 1, it is possible to load the transportation vehicle by loading the sand and the like scooped by the bucket into the hopper or by scraping up to the hopper, and the boom can be laterally or rearwardly loaded at the time of loading. Since it does not need to be turned up to, work efficiency is improved, it can be used even in a narrow place, wheels or crawlers are used to convey soil and the like backwards, to newly install a conveyor or to attach a conveyor to the vehicle body This has the effect of not requiring any structural change.

According to the loading machine of the second aspect, the vehicle height can be lowered to lower the center of gravity, and stable traveling can be performed.

In the loading machine according to the sixth aspect, the structure can be simplified by sharing the hopper.

By providing the distribution plate according to the seventh aspect, it is possible to convey earth and sand or the like on either the left or right side.
