[Detailed explanation of the idea] [Industrial application field]

This invention relates to a bucket device for a sweeper that brushes a surface to be cleaned, such as an inner bottom surface of a steel mill or a dock, and automatically scrapes up and collects accumulated dirt on the surface to be cleaned.

[Conventional technology]

A conventional bucket truck device of this type includes a rear bucket truck that is held on a vehicle via a bucket truck holding mechanism;
It consists of a front bucket seat attached to the front part of the rear bucket bar so that it can be opened and closed in the vertical direction, and a rotary brush that is installed inside the front bucket bar so that it can be grounded and is driven to rotate. Then, by rotating the rotary brush while the front bucket is closed and the rotary brush is grounded, the surface to be cleaned is brushed and dirt accumulated on the surface to be cleaned is scraped into the rear bucket and collected. There is.

[Problem that the invention attempts to solve]

In such a conventional bucket cart device, the dirt scraped up by the rotary brush accumulates in a mountain in the rear bucket cart, and the dirt increases toward the inside of the front bucket, especially on the front opening side of the rear bucket cart. It is not possible to efficiently accumulate garbage sequentially from the rear inside the rear bucket. As a result, even though the rear bucket compartment is not yet full of trash, the accumulated debris that moves toward the front bucket compartment and bulges up on the front opening side of the rear bucket compartment becomes entangled with the rotary brush.
There has been a problem in that the post-brushing cleaning operation using the rotary brush becomes extremely difficult and the efficiency of the operation is significantly reduced. In addition, in the case of the above-mentioned bucket cart, the rotary brush only scrapes up and collects dirt into the rear bucket cart, so the bucket cart must be taken in and out frequently in narrow work sites with low height and depth. In this respect as well, there was a problem of poor work efficiency. On the other hand, there was a device to prevent sand from sliding in the hopper of a road cleaning vehicle of Utility Model No. 45-31633, and Utility Model No. 52-
No. 168471 discloses a tractor-mounted road cleaning device that includes a conveyor that conveys dirt and earth scraped by a brush to a hopper at a separate location. However, with the above configuration, although it is possible to simply accumulate dust and the like in the hopper, it is not possible to move the dust and the like to the rear of the hopper as necessary. This invention was made to solve the above problems, and it can increase the ability of the rotary brush to scrape up and collect dirt, and it also makes cleaning work easier by moving dirt etc. in narrow spaces. The object of the present invention is to provide a sweeper bucket device that can perform the following functions.

[Means to solve the problem]

In order to achieve the above-mentioned problems, this invention has a rear bucket that is held in the vehicle via a bucket retaining mechanism, a front bucket that is attached to the front part of the rear bucket that can be opened and closed in the vertical direction, and an interior of the front bucket. In a sweeper bucket device comprising a rotary brush that is rotatably driven and installed so as to be able to ground on the rear bucket, (a) a conveyor is provided at the inner bottom of the rear bucket extending from the front opening side toward the back of the rear bucket; b) This is a technical measure in which a discharge port that can be opened and closed is installed at the rear of the rear bucket at a position where the conveyed materials can be discharged from the conveyor.

[Effect]

In this invention, during cleaning, the garbage scraped up into the rear bucket cart by a rotary brush is automatically transferred to the back of the rear bucket by a conveyor, and the garbage is stored in the bucket from the back one by one. I can do it. In addition, if you open the discharge port in a confined space, etc.
Garbage, etc. can be moved to a large space at the rear without having to take out and take out the bucket frequently.

By rotating both the rotary brush 13 and the rear bucket 11, the dirt scraped up by the rotary brush 13 is transferred by the conveyor 16 to the conveyed material discharge port 18.
Sent from In this way, after the accumulated garbage at the narrow work site is once moved to the front, the accumulated garbage can be collected in the bucket device 10 and transported and disposed of by dumping as described above. Note that the bucket device 10 is not necessarily limited to a bucket truck, but may be installed in the front of the vehicle 1 such as a loader, or in a forklift. Similar effects can be obtained.

[Effect of the idea]

As described above, according to this invention, the dirt scraped into the rear bucket cart by the rotary brush is sequentially sent to the deep part of the rear bucket cart by the conveyor, so that the dirt piles up only near the front opening of the rear bucket cart. Compared to conventional bucket devices of this type, the garbage collection capacity is greatly improved. Also, unless the rear bucket is full,
Since there is no risk that the dirt scraped into the rear bucket may become entangled with the rotary brush, the cleaning work can be carried out smoothly and efficiently. Furthermore, since the dirt scraped up by the rotary brush is sequentially sent to the back of the rear bucket by a conveyor, it is possible to remove dirt by opening the discharge port in narrow and narrow sites with low height and depth. Cleaning can be carried out after moving to a large space, and there is no need to frequently take out and take out buckets as in the past, so cleaning work can be carried out smoothly and efficiently even in such narrow spaces.
