Description

[Detailed explanation of the invention] This invention uses a rake attached to the chain to scrape up the debris that has landed on the front of the bar screen as the chain is being fed, and then dumps it into the debris directly below at the drop point near the drive wheels above the water. When dropping the waste under its own weight onto a part of the garbage conveyor, the head horizontal front scraper type has a structure that eliminates the drive shaft installed in the garbage dumping area, simplifying mechanisms such as the chute and guide rail, and making it possible to shorten the machine length. Regarding automatic dust remover.

In conventional front scraping type dust removers of this type, the drive shaft is installed within the garbage dumping range, so the length of the machine is longer to avoid the drive shaft. Since it is necessary to install the drive shaft as far back as possible from the machine, the length of the machine becomes longer, and the structural head and garbage dumping range become larger, resulting in an increase in the size of the entire device.

However, there are drawbacks such as dirt getting caught on the drive shaft, which is unsightly and causes problems in operation.

The present invention addresses these conventional drawbacks, and as explained below, the pair of left and right drive wheels are separately and independently supported in their respective bearing boxes without a connecting shaft, and Each of the driving wheels is interlocked with one intermediate shaft driven by a prime mover, and the bearing boxes of the left and right driving wheels are integrally connected by a connecting member.

The details will be explained below with reference to the embodiments shown in the drawings.
In the figure, 1 is a bar screen installed in a waterway a, and 2 is a rake for scraping up and removing garbage that has washed up and landed on the front of the bar screen 1 from below,
A large number of rakes 2 are installed at a required interval between a pair of left and right endless chains 3, 3 provided on both sides of the waterway,
As the chain 3 moves, they engage the bar screen 1 and rise, and the chute 5 continues from the fixed apron 4.
The waste is allowed to fall under its own weight onto the waste discharge conveyor 10 immediately below, and then plunges back into the water on the downstream side to be transported one after another.

The pair of left and right endless chains 3 are strung between a drive wheel 7 that is pivotally supported by a bearing box 6 installed on a fixed frame above the water and a lower driven wheel or fixed guide 8 at the bottom of the water, and is used to drive a motor such as a motor. 9, it is forwarded at a constant speed in the direction of arrow A.

As shown in FIGS. 2 and 3, the pair of left and right drive wheels 7, 7 are separately supported by bearing boxes 6, 6 without a connecting shaft, that is, in a state where they are separated from each other. Each of the intermediate shafts 11 is driven separately in conjunction with the single intermediate shaft 11 to be driven.

The chute 5 is placed as close as possible to the space between the driving wheels 7, 7, or in other words, the driving wheels 7, 7 are installed as close to the chute 5 as possible.

Figure 2 shows the intermediate shaft 11 positioned on the rear side of the drive wheels (as shown in Figure 1).
FIG. 3 shows a case where the drive wheel 7 is provided on the front side of the drive wheel 7.

A pair of left and right chain wheels 12.12 are mounted on the intermediate shaft 11.
and connect it to the drive wheel 7 through the chain 13.13.
, 7 and the integrated chain wheel 14.14,
Drive wheels 7, 7 are simultaneously driven to rotate in the same direction from an intermediate shaft 11 via a chain and a chain wheel by driving the prime mover 9.

Incidentally, the chain wheels 12 and 14 in the illustrated example are the chain wheels 12 and 14.
Although they are interlocked in 3, they may be interlocked by gear meshing instead of chain interlocking.

The bearing boxes 6, 6 of the left and right drive wheels 7, 7 are fitted into the groove 15 of the guide frame so that they can slide in the groove 15 when the chain 3 is under tension, and are connected so that they can simultaneously slide integrally. They are connected by a member 16.

In the case of Fig. 3, a pipe-shaped connecting member 16 is placed over the intermediate shaft 11, and both ends of the connecting member 16 are connected together via brackets, and this connecting part is connected to the fixed apron 4 and the chute 5 so that it does not get in the way of the passage of the rake. Make it hidden inside.

As mentioned above, the present invention has a pair of left and right drive shafts 7, 7 supported separately and independently in each bearing box 6 without a connecting shaft, and a chute is installed in the space between the two driving wheels 7, 7. The drive wheels 7, 7 are respectively linked to one intermediate shaft 11 driven by a prime mover 9, and each bearing box 6 of the left and right drive wheels 7, 7 is connected to a connecting member 16. Since they are connected together, when the garbage raked up by the rake 2 is dropped from the apron 4 to the chute 5, there is no drive shaft connecting the left and right drive wheels even though it is directly in front of the drive wheel 7 or at a close distance thereto. Therefore, the garbage discharge conveyor 1 directly below the space
0, which is directly dropped by its own weight without any obstacles,
Therefore, the apron 4 and the chute 5 following it can be fixed, and even if the driving wheel 7 is brought closer to the end of the chute 5, the dropping range will not be narrowed or restricted.

In addition, the structure of the guide rail 17, fixed apron 4, chute 5, etc. is simplified, and the length of the machine can be significantly shortened. Accordingly, the weight of the machine can be significantly reduced, and manufacturing costs can be reduced.

Furthermore, since the bearing boxes 6 of the pair of left and right drive wheels 7 are connected by the connecting member 16, even if the pair of left and right drive wheels are separate and independent and their movement is adjusted by chain take-up, their relative positions will always be maintained. It is constant and convenient in terms of operation and handling.
