Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust remover that automatically scrapes garbage after raking it onto the water surface, and includes a screen provided in a waterway and a rake frame that moves parallel to the screen. A comb-shaped rake provided on the screen, a rake wiper that moves together with the rake frame and inserted between the comb-shaped rakes, a spring that urges the rake wiper toward the rear of the rake, and a rear protruding piece of the rake wiper provided on the upper part of the screen are in sliding contact with each other. This dust remover consists of a wiper cam that swings the rake wiper forward against a spring, and the dust remover reliably scrapes up the dust that accumulates on the screen without leaving any residue behind, and also automatically blows out the scraped up dust. The purpose is to provide a dust remover that is

An embodiment of the present invention will be described based on the drawings.
Reference numeral 1 denotes a screen having a large number of parallel plates vertically disposed over the entire width of the waterway 2 to catch garbage, wood chips, and other debris flowing into the waterway 2. Reference numeral 3 denotes an endless chain provided on a rake frame 4 that moves parallel to the screen 1 and rises, and is rotated by being driven by a drive sprocket wheel 5 of the dust remover. Reference numeral 6 denotes a comb-shaped rake attached to the lower part of the frame body 7 of the rake frame 4, and the plates are arranged at equal intervals so that the tip side is inserted between the many plates of the screen 1 from the back side and protrudes. Become. Reference numeral 8 denotes a rake wiper in which a support shaft 10 is rotatably supported by a support part 9 on the upper part of the rake frame body 4, and the side plates 11 on both sides of the rake wiper 8 form a hook shape and are attached to one end which is a hook tip. It is equipped with a cam roller 12 rotatably, and at the lower end on the opposite side of the cam roller 12 there is a comb-shaped tip section made of a number of plates inserted at right angles between the plates of the comb-shaped rake 6. 1
form 3. Further, reference numeral 14 denotes a spring for tensioning the tip end 13 so as to abut the side surface of the frame body 7 of the rake frame body 4 and position it in a substantially vertical direction (at the rear of the rake 6). Through holes (not shown) are provided at the locations where the springs 14 of the frame body 7 pass through. Additionally, rake wiper 8 tip 1
Since each of the plates 3 is located between the plates of the comb-shaped rake 6, they are arranged at approximately the same position and at equal intervals as the plates of the screen 1, but they are placed close to the chain with respect to the plates of the screen 1. Since they are provided and pulled apart by the spring 14, they do not come into contact with each other. Reference numeral 15 denotes end plates with guide rollers 16 formed at both ends of the rake frame 4, which are connected to the chain 3 running in the letter-shaped chain guide groove 17, and are provided on the upper and lower sides of the end plate 15. The rotatable guide roller 16 guides the rake frame 4 along with the movement of the running chain 3 in contact with guide plates 18a and 18b attached to both sides of the entrance of the chain guide groove 17.

Reference numeral 19 denotes a mountain-shaped wiper cam which is disposed and fixed at an appropriate position above the water channel 2 of the dust remover as a swinging means for swinging the rake wiper 8, and is located approximately in the center so as to be close to the rake frame body 4 side. A protrusion 20 is formed. 21 is a garbage conveyor installed on the floor of the waterway 2, and 22 is a chute for moving the garbage discharged from the dust remover to the garbage conveyor 21.

To remove dust with the dust remover having the above configuration, the chain 3 is driven to rotate the rake frame 4, and the tip side of the rake frame 4 and the comb-shaped rake 6 are connected to the screen 1 at the bottom of the water channel 2. The screen 1 is inserted between the plates to scrape up the debris caught on the screen 1, placed on a comb-shaped rake 6, and raised along the screen 1. When the rake frame 4 rises above the water surface of the waterway 2 together with the chain 3, the garbage rises while being drained. When the rake frame 4 reaches position A, the cam roller 12 of the rake wiper 8 of the rake frame 4 comes into contact with the wiper cam 19, and when the rake frame 4 further rises and reaches position B, the protrusion 20 of the wiper cam 19 comes into contact with the rake frame 4. The rake wiper 8 swings counterclockwise (forward) as the cam roller 12 is guided, and the tip 13 of the rake wiper 8 moves toward the screen 1 while resisting the bias of the spring 14, thereby cleaning the dust and dirt on the comb-shaped rake 6. is discharged by the tip 13, passes through the chute 22, reaches the garbage conveyor 21, and is transported by the garbage conveyor 21 to a desired location. When the rake frame 4 further rises to position C, the wiper cam 19 is moved to a position where the cam roller 12 is removed from the protrusion 20 of the wiper cam 19 due to the bias of the spring 14.
As the rake wiper 8 is guided by the wiper cam 1, the rake wiper 8 is almost restored to its old vertical position.As the rake frame 4 continues to rise, the cam roller 12
9, the rake wiper 8 returns to its normal vertical position. In this way, scraping up garbage,
The discharging is completed, but when the chain 3 is further rotated, the rake frame 4 reaches the bottom of the water channel 2, and rake-up and discharging of garbage is started again.

The rake frame 4 can be provided in an appropriate number of one or more sets per chain, and the protruding length of the comb-like rake 6 of the rake frame 4 is determined by considering the size of the dust to be removed. It will be set as appropriate. The rake frame may be provided on either the front or back side of the screen, and the rake frame may be conveyed by an endless chain or by rotating an endless steel cable, belt, etc. .

In the dust remover of the present invention, the rake wiper is oscillated by the oscillating means, and the comb-shaped rake scrapes up and disposes the placed dirt, so even relatively large objects can be easily and automatically removed. It has the effect of being able to remove dust, and having a simple structure and a large processing capacity.

In addition, since the rake wiper is biased toward the rear of the rake by a spring, there is no problem with the rake's raking action.Furthermore, since the rake wiper is swung by a cam, dust removal work can be performed reliably. Moreover, it has the advantage of having a simple structure.
