The present invention is designed to lift up and down on the rear side of dredging and rotate the dredging device installed at a certain interval on the chain spoken to the upper and lower driving and interlocking sprockets. The present invention relates to a dredging device of a dredger which automatically lifts sediment in a pipe to perform dredging work more efficiently.

Conventional dredgers are dredging with a structure in which the rear side of the frame lifts the bucket vertically above the manhole by using a pulley that guides the woofer with a wire wound around the base drum. In order to pour out the deposits in the bucket pulled upwards, the worker had to draw around the manhole using a colander and then carry out the hard work of flipping it upside down. Due to the problem of dredging work being very slow, the dredging work was very slow compared to the working time because it was moved to the manhole position of the other section and then pulled it again and scraped the sediment into the bucket and spread it up the manhole.

Therefore, the present invention was devised to clear all the defects as in the prior art, and equipped with a scraper for scraping the deposits in the wire rope sewer pipe wound around the raw drum to collect the deposits at the bottom of the manhole, and at the rear side of the dredger Install the dredging device to move up and down, this dredging device is installed in the upper drive sprocket connected and driven to the motor, and the interlocking sprocket interlocked by the chain is installed at the lower part, and the chain rotates at regular intervals. It is a configuration to install the bucket. During dredging work, the dredging device is lowered and the lower part, that is, the bucket that rotates the interlocking sprocket, lifts up the sediment collected on the bottom of the manhole and the upper part, that is, the bucket that rotates the driving sprocket. Multiple ashes installed at regular intervals in the chain, configured to spill raised sediment Rotating the bucket automatically spreads the sediment at the bottom of the manhole and allows the dredger itself to continuously perform the pouring operation automatically, so that dredging work can be carried out quickly and efficiently in detail according to the accompanying drawings. The explanation is as follows.

The belt 3 is extended to the pulley 1 'of the prime mover 1 and the drive pulley 2' of the drive shaft 2 to rotate the interlocking shaft 4, and the wire drum 5 is rotated at the same time. In the dredging device which collects and loosens the sediment in the sewer pipe to the manhole side by winding or unwinding, a pair of guide rails 6 are installed vertically on the latter side of the dredger, and pneumatic or A dredging device 8 which is lifted and lowered by a cylinder 7 operated by hydraulic pressure is installed. The dredging device 8 includes an upper main body 11 in which a pair of drive sprockets 10 are laid on both sides of the upper side 9, and an elongated part 11 extending down from the upper main body 11 in a lengthwise manner. ') A pair of interlocking sprockets 10' are installed on the lower shaft 9 ', which is arranged horizontally below, and a plurality of rotating baskets 12 are provided on the driving sprocket 10 and the interlocking sprocket 10' at regular intervals. The configured chain 13 is spoken, and two guide wheels 14 are inserted into the guide rails 6 on both sides of the upper main body 11 to guide the lift. In addition, the upper side (9) is configured to rotate in a decelerated state by the motor (M) installed on one side of the upper body portion 11, the piston rod (7 ') of the cylinder (7) of the upper body (11) By attaching and attaching to an attachment hole formed on the closed end side, the long extension portion 11 'side of the dredging device 8 can be inserted into the manhole 15. In addition, as shown in another embodiment of FIG. 5, the rack 17 is attached to the closed end side rack gear 16 of the upper body 11 for a long time, and the gear 17 which rotates by a manual gear operating device or an automatic gear operating device is rack sized gear. It is configured to raise and lower the dredging device 8 in a configuration that engages (16).

Referring to the effect of the present invention configured as described above are as follows.

First, an embodiment in which the dredging device 8 is lifted and adjusted by means of a cylinder 7 which is operated by co-operation or hydraulic pressure will be described. 2) the manhole by driving the prime mover 1 to reciprocate the scraper (not shown) into the sewer pipe of the manhole 15 by hooking the wire rope wound on the raw drum 5 on the pulley 18. (15) After continuously scraping and depositing deposits on the floor, the cylinder (7) to operate in the lowered state immersed in the piston rod (7 ') cylinder (7) while lowering the dredging device (8), dredging device ( 8) itself, the guide wheels 14 on both sides are driven down the guide rails 6, the rotation being located in the interlocking sprocket 10 'built on the lower shaft 9' of the long extension 11 '. When the bucket 12 is able to spread the deposits collected on the bottom of the manhole 15, the dredging device 8 Stopping the strong operation to fix, then driving the motor (M) is the upper side (9) is rotated in a moderately decelerated state, so that the chain (13) spoken to the drive sprocket 10 and the interlock sprocket (10 '). Rotating basket 12 is formed at a predetermined interval is rotated, moved, at this time, the rotating basket 12 is rotated upside down in an upside down state, the rotating basket 12 is rotated upward in a straight state The rotating basket 12 passing through the interlocking sprocket 10 ′ of the lower part is to spread the deposit, and the rotating basket 12 passing through the driving sprocket 10 of the upper part to lift up the deposit. It is poured out.

Therefore, the dredging device 8 that rotates by appropriately adjusting the lowering into the manhole 15 is sequentially and successively sprayed deposits collected by the rotating buckets 12 scraped on the bottom of the manhole 15 as shown in FIG. In the process of passing through the upper drive sprocket 10, the manhole 15 is sequentially poured into the bottom, so that the dredging operation can be continued continuously, so that the efficiency of dredging work can be expected.

In addition, the embodiment of FIG. 5 is an embodiment in which the dredging device 8 is configured to be able to use the power of the prime mover 1 without using pneumatic or hydraulic cylinders 7 or to adjust the lifting and lowering by an artificial operation method of an operator. In this embodiment, the rack gear 16 is vertically attached to the upper main body 11 of the dredging device 8, and the rack gear 16 is configured to be exposed to the outside of the automatic gear operating device or the manual gear operating device. 17 is a configuration of an embodiment in which the dredging device 8 is raised and lowered in a configuration such that the rack size gear 16 moves up and down by engaging the gear 17 and rotating the gear 17 in place. Since it does not need to install the lifting device, it has the advantage of low production cost, while artificially raising and lowering is possible, and the rotating bucket is formed at regular intervals so that the dredging device is installed during dredging work. The dredging work can be carried out quickly and efficiently because the sediment collected on the bottom of the manhole can be continuously and automatically scooped up and poured into the floor around the manhole by adjusting the descent into the hole and then rotating it. It is a practical design with the advantage of double the efficiency.
