Description

The present invention relates to a dust removal system in which a movable rake is driven and circulated by the hydraulic power of a water wheel arranged in a water channel, and the movable rake rakes up and removes dust, weeds, etc. that have flowed to a fixed rake installed in the water channel.

Conventionally, as a device for removing garbage, weeds, etc. flowing down a waterway, the garbage, weeds, etc. that flow down are caught by a grid-like screen installed in the waterway, and the garbage, weeds, etc. that are caught are caught along the screen or a fixed rake. There is known a dust remover that mechanically rakes up dust, weeds, and the like with a movable rake (which circulates in one direction) and discharges dust, weeds, and the like to a predetermined position above a water channel. For example, endless chains are arranged diagonally up and down on both left and right sides of a screen installed in a water channel, and both ends of a movable rake are connected to these left and right endless chains, and the movable rake is moved by the circulating motion of the endless chain. There is a structure in which dust, weeds, and the like that flow onto the screen or the like are removed by circulating and moving along the screen or the like and raking up the movable rake that moves upward. This was provided with a drive sprocket for circulating the endless chain and a drive mechanism for driving the drive sprocket.
In addition, when an electric motor is used for the drive mechanism that drives the drive sprocket, a power source is required. Since electricity costs are also required and running costs are high, there is also a hydraulically driven dust remover in which a water wheel is placed in the water channel, and the water current flowing through the water channel is used to rotate the water wheel, and the water power of the water wheel drives and circulates the movable rake. was

As a related technology, a shield plate is provided at the bottom of the water wheel to prevent the water flow hitting the blades of the water wheel from entering the lower side of the water wheel and the hydraulic power not acting on the water wheel. There is a technique for providing a hydraulically driven dust remover capable of removing dust (see Patent Document 1).

In addition, as a related technology, a water-powered dust remover is equipped with a conveyor for transportation, and by dropping garbage, weeds, etc. from the movable rake of the dust remover onto the conveyor, the garbage, weeds, etc. can be efficiently discharged to a predetermined discharge place. There is a technique of conveying to the (see Patent Document 2).

JP-A-11-131453 Japanese Patent No. 5468649

However, in the techniques disclosed in Patent Document 1 and Patent Document 2 above, regarding the mechanism for transporting garbage, weeds, etc. that are raked up by the movable rake and dropped from the movable rake at a predetermined position and discharged, In the first place, there is no such mechanism, or a belt conveyor is used for transportation, and there is a problem that garbage, leaves of weeds, etc. slip on the belt and do not move, and are not conveyed smoothly. In addition, when dropping garbage and weed leaves from the end of the conveyor and discharging them, it is difficult to discharge a sufficient amount of garbage and weed leaves if the distance from the drop point to the ground is short. There was a problem that it would become (accumulate immediately).

In addition, when garbage, weeds, etc. fall on the ends of the conveyor (left and right with respect to the direction of travel), they become tangled or clogged in the gaps between the belts, slats, etc. and the components to which the belts, slats, etc. are attached. There was a problem that the conveyor stuck and stopped moving. In addition, it was necessary to ensure that garbage and weeds fell on the belts and slats, etc., especially near the center of the belts and slats (meaning the center on the left and right with respect to the traveling direction) so as not to scatter. . On the other hand, if it accumulates only on the line near the center of the belt, slat, etc., when it is dropped from the end of the conveyor and discharged, the distance from the drop point such as the ground will be shortened quickly, and garbage will be collected. There is a problem that it is difficult to discharge a sufficient amount of leaves of weeds (they quickly accumulate on one line).

In addition, if the dust, weeds, etc. raked up by the movable rake fall from the claws of the movable rake from the top of the dust remover by the rotational movement of the movable rake and the action of gravity, they may become entangled in the claws of the movable rake or between the claws. Since clogged dust and weed leaves remain without falling off, a cleaning mechanism corresponding to the number and shape of the claws of the movable rake is required, and scraped off dust and weed leaves can be removed smoothly. In addition, it has been required to be supplied on a conveyor so as not to scatter to the opposite side. Also, when the claw of the movable rake passes through the cleaning mechanism, dust and leaves of weeds left on the claw of the movable rake clog the gap between the claw of the movable rake and the cleaning mechanism, causing the movable rake to become stuck. There was a problem that it would stop working. Also, regarding the mounting plate to the conveyor formed to form an angle of approximately 90 degrees with the claw of the movable rake, the cleaning mechanism can be moved when dust or leaves of weeds are clogged between the base of the claw and the mounting plate. There is a problem that the movable rake is caught when the pawl of the rake passes through, further increasing the number of factors that cause the rake to become stuck and stop moving.
It should be noted that the present invention is a product-level product in which sample products have been developed through trial and error, and is not merely an idea stage.

It is a figure which shows the structure of the conveyor in the dust removal system which concerns on embodiment of this invention. It is a figure which shows the structure of the movable rake in the dust removal system which concerns on embodiment of this invention.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 collectively show the overall configuration of a dust removal system according to an embodiment of the present invention.
Of the basic configuration of the dust remover 2, portions similar to those of known dust removers can be realized by applying known techniques, and detailed description thereof will be omitted as appropriate.

The dust removal system S includes a fixed rake 1 and a movable rake 3 driven and circulated by hydraulic power to lift (raise) dust, weeds, etc. (garbage) that flowed into the fixed rake 1 and drop them onto a slat conveyor 6. It is composed of a dust remover 2 that is conveyed by a slat conveyor 6 and discharged to the ground beside a waterway.

A separate fixed rake 1 is installed on the upstream side of a water channel R such as an irrigation channel or a drainage channel to catch garbage, weeds, etc. that flow into the water channel. The stationary rake 1 has a plurality of protrusions (five in this case) having a shape with a small head loss on the bottom surface, which are provided at predetermined intervals in a comb shape so that the claws 31 of the movable rake 3 can pass through the protrusions. there is

The water from the upstream rotates the water wheel 4 of the dust remover 2 held on the water surface of the water channel R on the downstream side of the fixed rake 1, and the mesh eye clutch 7 of the dust remover 2 is set to neutral (the power transmission shaft 10 and the water wheel 4 ) to connect (connect the interlocking connection between the power transmission shaft 10 and the water turbine 4), and the bevel gearbox 12 reverses the rotation direction.

The hydraulic power of the water wheel 4 rotates a power transmission shaft 10 supported by the base frame 5 of the dust remover 2 , rotates the drive sprocket 8 and the conveyor drive sprocket 11 , and rotates the movable rake 3 and the slat conveyor (chain conveyor) 6 . gives a driving force to circulate the The water turbine 4 may be provided with a water turbine cover for safety and the like.

A circulating endless chain 13 is wound around the driving chain sprocket 8 and the driven chain sprocket 9 of the dust remover 2, respectively. A movable rake 3 is laid horizontally between the endless chains 13, and interlocked with the circulating motion of the endless chains 13, the movable rake 3 is circulated.

When the water wheel 4 of the dust remover 2 rotates, the power transmission mechanism such as the power transmission shaft 10 works to rotate the drive sprocket 8 . As the drive sprocket 8 rotates, the endless chain 13 meshing with the drive sprocket 8 circulates and rotates the driven sprocket 9 .

As the left and right drive sprockets 8 rotate together, the left and right endless chains 13 meshing with the drive sprockets 8 circulate at the same speed in the same direction. That is, the endless chain 13 on the downstream side moves downward, and the endless chain 13 on the upstream side moves upward.

At least one (here, two) movable rakes 3 are laid horizontally between the circulating endless chains 13 on both sides. It circulates in the same direction as the circulating direction of In other words, the movable rake 3 is moved in conjunction with the circulating motion of the endless chain 13, and the claws of the movable rake 3 move garbage, weeds, etc. flowing in the water channel attached to the fixed rake 1 upwards of the fixed rake 1. When the dust remover 2 is lifted by the parts 31 (four here) and moved downward from near the top of the dust remover 2, garbage, weeds, etc. fall from the claw parts 31 of the movable rake 3 onto the slat conveyor 6 due to gravity. It is conveyed by a slat conveyor 6 and discharged from its end to the ground (bank) beside the waterway. The movable rake 3 is lowered as it is, passes through the position facing the fixed rake 1, picks up garbage, weeds, etc. again, and repeats the same operation.
By arranging two movable rakes 3 at opposite positions of the endless chain 13, more efficient removal of dust, weeds, and the like is achieved.

Garbage, weeds, and the like dropped from the claw portion 31 of the movable rake 3 are conveyed by the slat conveyor 6 . This is because garbage, weeds, and the like slip and do not move on the belt conveyor.
The slat conveyor 6 attaches slats (elongated flat steel plates) to the attachments of the conveyor chains on both sides, and conveys an object placed on the slats.
As shown in FIG. 5, one end side of each slat in the advancing direction is raised by about 1 cm to form a comb-like shape. Furthermore, the comb-like shape of each slat is alternately arranged in two different shapes, namely, roughly triangular jagged slats with pointed tips and uneven slats with parallel tips. This prevents dust, weeds, and the like from slipping. The comb tooth shape of each slat is not limited to that shown in FIG. 5, and different shapes may be arranged in order as long as the same effect is achieved.

Also, the slat conveyor 6 is installed at an angle so as to form an upward slope in the traveling direction. As a result, compared to the case of horizontal installation, when discharging garbage, weeds, etc. from the end of the slat conveyor 6 to the ground (bank) beside the waterway, etc., the distance from the falling point to the ground, etc. is reduced. The distance is secured, and more garbage and weeds can be collected.

As shown in FIGS. 1 to 4, the dust remover 2 has a first shooter (a device that uses the height difference to slide the workpiece like a slide and serves as a guide plate for dust, weeds, etc.). 14 are provided so as to form a slope beside the slat conveyor 6 . Since the terminal end of this slope overlaps with the slat of the slat conveyor 6, garbage, weeds, etc. will surely fall on the slat of the slat conveyor 6. - 特許庁
In addition, the dust remover 2 is provided with a second shooter 15 facing the first shooter 14 so as to form a slope beside the slat conveyor 6 so as to prevent dust, weeds, etc. from scattering in the opposite direction. ing. Since the terminal end of this slope is also positioned to overlap the slat of the slat conveyor 6, garbage, weeds, etc. will surely fall onto the slat of the slat conveyor 6. - 特許庁

In addition, the first shooter 14 and the second shooter 15 are each installed so as to form an "inverted V" shape that expands in the traveling direction of the slat conveyor 6 in plan view. This is because when garbage, weeds, etc. fall on the ends of the slat conveyor 6 (left and right ends with respect to the traveling direction), they become tangled or clogged in the gaps between the slats and the structural members to which the slats are attached, and remain there. , Since the conveyor may not move, it is necessary to ensure that garbage, weeds, etc. fall on the slats, especially near the center of the slat (meaning the center of the left and right with respect to the direction of movement), so as not to scatter. On the other hand, if garbage, weeds, etc. are concentrated and deposited only on the line near the center of the slat, the distance from the drop point such as the ground will quickly become short when they are dropped from the end of the slat conveyor 6 and discharged. It is difficult to discharge a sufficient amount of garbage and weed leaves (all of them accumulate under one line), so not only on the line near the center of the slat, but also on the entire left and right width of the slat It is intended to be distributed over

The first shooter 14 is provided with four notches 141 corresponding to the number and shape of the claws 31 of the movable rake 3 as a cleaning mechanism. If the dust, weeds, etc., scraped up by the claw portion 31 of the movable rake 3 are dropped from the claw portion 31 by the action of gravity from the top of the dust remover 2, the dust, weeds, etc. entangled or clogged with the claw portion 31 cannot be dropped. Therefore, when the claw portion 31 passes through the notch portion 141 of the first shooter 14 by the cleaning mechanism, dust, weeds, etc. remaining on the claw portion 31 come into contact with the notch portion 141 and are scraped off. trying to be dropped. It should be noted that the dust, weeds, and the like scraped off by this are smoothly slid down along the slope (not the vertical plane) of the first shooter 14 and are supplied to the vicinity of the center of the slat.

When the pawl portion 31 of the movable rake 3 passes through the notch portion 141 of the first shooter 14, dust, weeds, etc. remaining on the pawl portion 31 clog the gap between the pawl portion 31 and the notch portion 141, causing the movable rake 3 to become clogged. Since there is a risk of stacking, as shown in FIG. In addition, the cleaning mechanism of the first shooter 14 effectively scrapes off the dust, weeds, etc., so that the dust, weeds, etc. do not remain. .

Further, regarding the attachment plate portion 32 to the dust remover 2 (between the endless chains 13 on both sides) formed to form an angle of approximately 90 degrees with the base portion of the claw portion 31 of the movable rake 3, the base portion of the claw portion 31 If dust, weeds, or the like are clogged between the portion and the mounting plate portion 32, the movable rake 3 will be caught and stuck when the pawl portion 31 of the movable rake 3 passes through the notch portion 141 of the first shooter 14. Therefore, as shown in FIG. 6, an oblique protection is provided between these two surfaces (the base of the claw portion 31 and the mounting plate portion 32) forming an angle of approximately 90 degrees. As the member 321, for example, a plurality of rod-shaped round steels (3 mm in diameter) are installed by welding or the like to prevent clogging with dust, weeds, and the like. A part of the protective member 321 may be configured such that the peeling member 311 is stretched/bent.

The above-described embodiments are preferred embodiments of the present invention, and various changes in shape, size, ratio, etc. can be made without departing from the gist of the present invention. For example, the material may be stainless steel.
