Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a screen belt in a waste treatment device.

(Prior Art) Conventionally, screen belts used in waste disposal equipment have been cut to a certain length, with holes drilled in the ends of the belt, pulled using a special tool, and connected with connecting fittings.

(Problems to be solved by the invention) In the above-mentioned known method, when the belt becomes slack,
This required the work of drilling holes at both ends of the belt and the work of pulling it using a special tool, making the connection operation extremely troublesome.

(Means for solving the problem) Therefore, the present invention is based on the vertical frames 1, 1 arranged on the left and right sides.
A passive rotating roll 3 is disposed in the lower part between them, and a driving rotating roll 4 is disposed in the upper part between the vertical frames 1, 1, and the outer peripheral surfaces of the passive rotating roll 3 and the driving rotating roll 4 are provided with a Grooves 5 are formed at predetermined intervals, and a synthetic resin belt 6 is wound around the upper and lower grooves 5, 5, and the synthetic resin belt 6 has continuous holes at predetermined intervals in the length direction. 7, the synthetic resin belt 6 is formed into an end belt, an upper connector 17 is brought into contact with the separation part 16 from above, a lower connector 18 is brought into contact with it from below, and the upper connector 17 is provided with a set screw. 19, and an insertion port 22 into which the set screw 21 is inserted. 25 and an engaging portion 26 that engages are integrally provided as a screen belt in a waste disposal device.

(Example) An example of the present invention will be described with reference to the drawings.
is a pair of vertical frames on the left and right, the lower ends are connected by horizontal board 2,
A passive rotating roll 3 is attached to the lower part between the vertical frames 1, 1, and a driving rotating roll 4 is attached to the upper part thereof, and grooves 5 are formed in the passive rotating roll 3 and the driving rotating roll 4 at desired intervals in the axial direction. A synthetic resin belt 6 is wound around the groove 5. The synthetic resin belt 6 has continuous holes 7 formed at desired intervals, into which the rake pins 8 are inserted.

The rake-up pin 8 is linear, and has a linear insertion part 9 inserted into the continuous hole 7 on the base side of its lower half, and a retaining bulge 10 at the tip of the linear insertion part 9.

The upper half of the rake pin 8 is formed into a straight rake part 11, and the straight rake part 11 is formed to be slightly larger in diameter and length than the straight insertion part 9.

The synthetic resin belt 6 is formed into an end belt by cutting a long belt, and an upper connector 17 is inserted from above at the cut-off portion 16, and a lower connector 18 is attached from below.
to touch.

One end of the upper connector 17 has an insertion opening 20 into which a set screw 19 is inserted, and the other end has an insertion hole 20 into which a set screw 19 is inserted.
An insertion port 20 into which the set screw 21 is inserted is integrated into the insertion port 22, an insertion portion 24 into which the large head diameter portion 23 of the set screw 21 can be loosely inserted and removed, and an engaging portion 26 into which the neck portion 25 of the set screw 21 engages. to be established.

In addition, 12 is a motor, 13 is a drive pulley,
14 is a passive pulley, and 15 is a belt.

(effect) Next, we will discuss the effect.

Since the present invention has the above-mentioned configuration, when the horizontal plate 2 is immersed in the wastewater waterway, the motor 12 is energized, and the drive rotary roll 4 is rotated via the drive pulley 13, belt 15, and passive pulley 14, the drive A synthetic resin belt 6, which is stretched between the rotating roll 4 and the passive rotating roll 3, rotates to form a linear scraping part in which a linear insertion part 9 is inserted into a continuous hole 7 of the synthetic resin belt 6. 11 to scrape up and remove the filth in the sewage waterway.

The synthetic resin belt 6 is formed by cutting a long belt to form an end belt, and an upper connecting tool 17 is brought into contact with the cut-off portion 16 from above, and a lower connecting tool 18 is brought into contact with the lower connecting tool from below. One end of the tool 17 is provided with an insertion port 20 into which the set screw 19 is inserted, and the other end is provided with an insertion port 22 into which the set screw 21 is inserted.
Insertion part 24 and set screw 2 that 3 can be inserted and removed loosely
Since the engaging portion 26 with which the neck portion 25 of the synthetic resin belt 6 engages is integrally provided, the insertion opening 20 of the upper connector 17 is inserted into the continuous hole 7 formed in the separation portion 16 of the synthetic resin belt 6. Place the lower connector 18 into the lower part of the continuous hole 7 of the cut-off part 16 at the other end of the synthetic resin belt 6, insert the set screw 21 from above, and insert the set screw 21 from above. Attach the connector 18.

(b) Holding the detachable part 16 of the synthetic resin belt 6 with both hands, insert the large head diameter part 23 of the set screw 21 into the insertion opening 2.
2, insert the neck part 2 of the setscrew 21 from below.
5 is engaged with the engaging portion 26 of the insertion port 22.

C. Tighten the set screw 19 to connect.

(Effect) Conventionally, in order to make a commercially available straight V-belt into an endless screen belt, a certain tension is required, so the upper and lower V-grooves are cut shorter than the distance between the rotors and holes are drilled at both ends to maintain a constant tension. The method was to pull the tension by hand or use a special tool to keep both ends in contact with each other, and then fasten the top and bottom plates with screws. Ta.

The hook joints of this invention are in the shape of a gourd, so each one is temporarily fixed, and then they are hooked together using the gourd-shaped holes so that the screws are placed in the designated hole positions. Also, if you tighten the screw with a screwdriver, it will be firmly joined.

When a screen belt is used, it gradually stretches and spins idly, but the conventional method is to cut the belt each time to make it shorter, drill a hole, and reconnect it, but this process is difficult. Therefore, it had to be replaced with a new one, but by using the new hook joint, this can be easily done by simply moving the joint part to the next hole.
