And a catching member rotatably attached to a part or all of the remaining connecting pieces, and a dust catching device for catching the dust in at least a dust catching area on the ascending side of the orbiting area of the orbiting member. A second guiding unit for setting the catching member in a hanging posture in a dust collecting area above the dust catching area while having the posture.

In the dust remover according to the present invention, the catching member is in a dust capturing position in the dust capturing region to capture dust and the like, and is located above the dust collecting region in a hanging position by the second guide means. In the has a function of dropping garbage and the like, the scraping member protruding outside the orbiting area of the orbiting member,
It has a function to surely move dust and the like captured by the capturing member. Since the capturing member having such a function can drop and collect dust and the like by being in the hanging posture, the position of the dust collection area can be any position on the rising side of the orbiting area of the orbiting member. Therefore, it can be set low, so that dust and the like can be collected at a low position,
The cost can be reduced, and the installation condition of the collecting device such as a hopper can be improved.

In the dust remover according to the present invention, the capturing member is rotatably attached to a connecting piece near one end in the circumferential direction, and the guide means is configured to raise an upper side of a circumferential area of the circumferential member to a rising side. The second guide means guides the vicinity of the other end in the circulating direction of the capturing member in the garbage capturing area along the circling area of the circulating member, while the second guide means is configured to be inclined rearward of the lower part. In the region, the vicinity of the other end in the circling direction of the capturing member is opened, so that the capturing member can be in a hanging posture by its own weight.

In this configuration, the capture member is rotatably attached to the connecting piece near one end in the circumferential direction, and the guide means moves the upper portion of the orbiting region of the orbiting member higher than the lower portion of the ascending side.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described specifically.

FIG. 1 is a front view showing a dust remover according to this embodiment, FIG. 2 is a front view showing a part of the dust remover, FIG. 3 is a left side view showing a part of the dust remover, and FIG. It is a top view which shows a part of the dust remover.

The dust remover includes a pair of endless orbiting members, for example, an endless chain 15, which are separated from each other in the front-rear direction on the paper surface of FIG. The driving means has a pair of gears 22 meshing with the upper inner peripheral surface of both endless chains 15 respectively, and another gear 22 connected to a motor 23 via an endless roller chain 23a. These three gears 22 are connected by a common shaft (not shown). With this driving means, both endless chains 15 circulate in the direction of the arrow at the same speed and synchronously (see FIG. 1).

An L-shaped fixing member 11 is fixed to each endless chain 15 via a supporting member 11a. The two fixing members 11 are provided for every three links of the endless chain 15, and every other fixing member 11 in the circling direction has a scraping member 13 which is hung over these at the upstream part in the circulating direction. The endless chain 15 is mounted so as to protrude outward from the orbital region. In this embodiment, the scraping member 13 is an L-shaped plate-shaped fixing member 11.

In the present embodiment, the capture member 17 includes a cylindrical member 17b rotatably mounted on the shaft 14 via a bearing 17a and the like, and a plurality of rod-shaped capture members mounted on the cylindrical member 17b at intervals. Piece 17
c, a rectangular plate 17d attached to the outside of both outermost members in the same manner as the capture piece 17c, and a support member 17e hung on the rectangular plate 17d and connected to each capture piece 17c.
Consists of Both rectangular plates 17d of the capturing member 17
, A roller 17g is attached via a support member 17f, and the roller 17g is guided by a roller guide 18.
The roller 17g and the roller guide 18 function as a second guide.

As shown in FIG. 5, when the cylindrical member 17b rotates around the shaft 14 as shown in FIG. 5, the capturing piece 17c is brought into contact with the connecting piece 12, and the capturing attitude is dropped from the connecting piece 12. Posture changes over. Capture piece 17
c intersects the scraping piece 13a in the capture posture, and more specifically, becomes substantially orthogonal.

The endless chain 15 is guided in a concave groove 21 provided in a guide member 20 as shown in FIG.
The concave groove 21 is provided for the capturing member 1 fixed to the endless chain 15.
7, the front (upward) upper portion is inclined more rearward than the front lower portion, and the rear (downward) upper portion is more rearward lower than as shown in FIG. Is also formed to have a horizontal section L parallel to the water bottom B at the bottom. Therefore, each endless chain 15
Guided by the guide member 20, each endless chain 15, the catching member 17, and the scraping member 13 are also
It orbits in a shape similar to the shape of No. 1 and passes under the water surface S and in the atmosphere.

The roller guide 18 is provided on the capturing member 1.
There is a part (18A) of the front upper part of the orbital area 7 and a part (18B) extending from the rear upper part to the middle part. An area 18A where the roller guide 18 is not formed partially in the front upper part of the orbiting area is a dust collection area for dropping and collecting dust and the like, and the dust collection area 18A.
A horizontal portion 18a is formed on the front side, and a raised portion 18b and an arc portion 18c following the raised portion 18b are formed on the rear side. The horizontal portion 18a is set so as to gradually move away from the orbiting region of the scraping member 13, and the rising portion 18b is gradually approached to the orbiting region of the scraping member 13. Below the refuse collection area 18A, there is provided a belt conveyor 40 which circulates so as to pass in the vertical direction, and a hopper 41 for receiving dropped trash and the like is attached outside the belt conveyor 40.

The horizontal section L is set to have a length in which at least one scraping member 13 can exist, for example, a dimension such that adjacent scraping members 13 are located at both ends of the horizontal section L. . Note that the horizontal section L may be longer.

The operation of the dust remover thus configured will be described.

The two endless chains 15 are formed by a pair of guide members 2.
The trapping member 17 which is guided by the shaft 0 and passes under the water surface S and through the atmosphere, and is attached to the two endless chains 15 via the fixing member 11 and the supporting member 11a.
Is changed as described above by the roller 17g being guided by the roller guide 18. When orbiting the front side, the capturing member 17 is in a capturing position in contact with the connecting piece 12 to capture dust and the like, and the scraping member 13 prevents the dust and the like from falling. Here, an area where the capturing member 17 captures dust and the like is referred to as a dust capturing area.

As described above, when approaching the refuse collection area 18A, the capturing member 17 is gradually separated from the connecting piece 12 by the horizontal portion 18a and opens, and after passing through the horizontal portion 18a, the capturing member 17 is in a hanging posture. As a result, dust and the like fall naturally and are collected by the hopper 41.

Thereafter, the roller 17 is placed on the rising portion 18b.
g abuts, the capture member 17 gradually closes to the connecting piece 12 and closes. When the capture member 17 reaches the arc portion 18c, the capture member 17 is completely closed, and while passing through the arc portion 18c, the roller 17 is closed.
g is guided by the circular arc portion 18c, and the completely closed state is maintained.

Thereafter, the non-forming portion 18 of the roller guide 18
B, the capturing member 17 is moved by its own weight.
, Thereby descending while maintaining the closed state. Thereafter, when the catching member 17 reaches the bent portion 18d of the roller guide 18, the catching member 17 moves horizontally while the scraping member 13 is close to the water bottom B while passing through the horizontal section L. At this time, since the length of the horizontal section L is such that at least one scraping member 13 is present, even if there is a gap between the water bottom B and the capturing member 17, the scraping member 13 may Is captured, moved to the front side, and collected by the hopper 41 in the same manner as before.

Therefore, according to the present embodiment,
The capturing member 17 is a roller 17g by a roller guide 18.
According to the guide state, the scraping member 13 is configured to be in contact with or separated from the scraping member 13, and the capturing member 17 is in a dust capturing position in the dust capturing region to capture dust and the like, and in the dust collecting region above it. Since the upstream end (the lower end in FIG. 1) of the capturing member 17 in the circulating direction is opened to take a hanging posture for dropping garbage and the like, the position of the garbage collection area is higher than the upper end position on the front side of the circulating area of the endless chain 15. Since it can be set at an arbitrary position that is low (above the water surface), it can be set low, so that dust and the like can be collected at a low position, cost can be reduced, and the collection device such as the hopper 41 can be used. Installation conditions can be improved.

Further, in the case of this embodiment, the capture member 17 has its downstream end (upper end in FIG. 1) in the circumferential direction rotatably mounted on the shaft 14 as a connecting piece, and has a concave groove. Since the front upper portion 21 of the endless chain 15 is inclined more rearward than the front lower portion, the capturing member 1
7 can be in a hanging position on the front side of its orbital area. In addition, the endless chain 1 is set in a state in which the concave groove 21 inclines the rear upper portion of the endless chain 15 around the circling region more rearward than the rear lower portion.
Since the guide member 5 is guided, the catch member 17 comes into contact with the scraping member 13, specifically, the connecting piece 12 by its own weight. Therefore, the roller guide 18 can omit a part (18B) on the rear side in the revolving region of the revolving member.

Further, according to the present embodiment, since at least one scraping member 13 exists in the fixed section L where the lower end of the orbiting area of the scraping member 13 approaches the water bottom B, the trapping is performed. Even if there is a gap between the member 17 and the water bottom portion B, dust and the like that should escape from the gap to the downstream side will be captured by the scraping member 13, and it is possible to reliably collect the dust and the like. Become.

In the above-described embodiment, the catching member 17 has a length extending over three links of the endless chain 15. However, the present invention is not limited to this. It is also possible to use 15 or less links having a length dimension of 2 links or less. In particular, when the number of links is four or more, the separation distance between the scraping members 13 in the circumferential direction is increased, so that it is possible to collect a larger dust and the like.

Further, in the above-described embodiment, the scooping member 13 is provided every other one in the circumferential direction of the capturing member 17, but the present invention is not limited to this. For example, the scraping members 13 may be provided in each of the circumferential directions of the capturing members 17, or the scraping members 13 may be provided in every two or more of the capturing members 17 in the circumferential direction. In particular, in the case of the latter, the scraping member 13 in the circumferential direction is used.
By increasing the separation distance between each other, it is possible to collect extremely large trash and the like.

Further, in the above-described embodiment, the capturing member 17 is configured such that the downstream end (the upper end in FIG. 1) in the circulating direction is rotatable, and the upstream end is opened and closed. On the contrary, it is needless to say that the capture member can be configured such that the upstream end (the lower end in FIG. 1) in the circulating direction is rotatable and the downstream end is opened and closed.

In the above-described embodiment, the capturing member 17 having the bar-shaped capturing piece 17a is used, but the present invention is not limited to this. For example, a plate material provided with a large number of drain holes may be used.

In the above-described embodiment, a member having a bar-shaped scraping piece 13a is used as the scraping member 13, but the present invention is not limited to this. For example, similarly to the capturing member 17, a plate member provided with a large number of drain holes may be used. When such a raking member is used, it is possible to capture and collect sand, gravel, and the like at the lower end of the orbital area. In this case, without using a scraping member made of a flat flat plate material,
As shown in FIG. 10, it is preferable to use a scraping member 13 'having a U-shaped scraping plate 13A in which both sides of a plate material having a drain hole 13C are bent in the circumferential direction. When the scraping plate 13A is used, sand and the like can be scooped when the scraping member 13 'passes through the bottom of the water, and the sand and the like can be prevented from dropping on the way. Further, when the capturing member 17 is opened in the refuse collection area 18A, the captured trash and the like existing on the sand or the like falls first, is collected by the hopper 41, and is still collected by the hopper 41.
The sand and the like remaining in 3A are naturally dropped when the opening 13B of the U-shaped scraping plate 13A faces obliquely downward after passing over the upper end of the orbiting area, and a hopper (not shown) installed in the falling area. The hopper 41 may be collected by another hopper. In this way, sand and the like and dust and the like can be separated and collected.

In the above-described embodiment, the roller guide 18 for guiding the roller 17g at the drop position 18A is provided in a state where one of the rollers is opened. However, the present invention is not limited to this, and is shown in FIG. As described above, the roller pressing member 19a may be provided above the horizontal portion 18a, and the roller pressing member 19b may be provided above the rising portion 18b. By doing so, it is possible to reliably guide the roller 17g. Further, the roller guide for guiding the roller 17g may be formed in an endless state, and a roller pressing member may be provided around the entire circumference of the roller guide. In this case, the roller 17g is guided so as to pass between the roller guide and the roller pressing member. Therefore, the drooping posture in which the posture is changed so as to drop the dust and the like in the dust collection area may be such that the capturing member 17 is not in the drooping state due to its own weight, but is in a posture close to the drooping state or in the drooping state.

In the above-described embodiment, FIG.
As shown in FIG. 7, the tip of the scraping member 13 approaches the actual water bottom in a certain section L. However, the present invention is not limited to this, and the movement of the tip of the scraping member 13 as shown in FIG. The gap adjusting member 43 having the upper surface 43a along the area may be provided on the water bottom B. In this case, since the upper surface 43a of the gap adjusting member 43 constitutes the water bottom surface, the length dimension along the water bottom B excluding the gap adjusting member 43 in the movement area of the tip of the scraping member can be shortened. The length of the endless chain 15 can be reduced even if the height is the same as that of the dust remover that does not use the gap adjusting member 43,
Cost can be reduced.

In the above-described embodiment, the endless chain is used as the orbiting member. However, the present invention is not limited to this, and an endless belt or the like can be used.

Further, in the above-described embodiment, the type in which the hopper is moved by the conveyor is used, but the present invention is not limited to this, and it is needless to say that the present invention can be applied to the type in which the hopper is stationary. It is.

[0041]

As described above in detail, in the case of the present invention, the catching member takes a dust trapping posture in the dust catching area to catch dust and the like, and the second guide means in the dust collecting area above it. Since the dust and the like can be dropped and collected by the hanging posture, the position of the dust collection area can be set at an arbitrary position on the rising side of the orbiting member, so that the dust can be set low. The collection can be performed at a low position, the cost can be reduced, and the installation condition of the collection device such as a hopper can be improved.
