Abstract

PURPOSE:To discharge sedimentary sand without being affected by amounts of incoming soil and sand by a method in which a reversing-preventing mechanism to run a chain when lowering an elevator and an elevator frame are provided to the elevator, and the elevator is lowered when a bucket provided to the elevator frame reaches the sedimentary sand. CONSTITUTION:A groove-shaped side pillar 6 is fitted into an elevator 2 provided to an arm 1 to form an elevator frame 4 to be guided for elevation. Sprockets 8 and 7 are provided to the upper and lower parts of the frame 4, an endless chain 9 is engaged to the sprockets 8 and 7, and a bucket 10 to be turned together is provided to the sprocket 7. A reversing-preventive mechanism 11 to run th chain 9 as the elevator 2 goes down is also provided. When the arm 1 is lowered and the sprocket 7 reaches sedimentary sand, the arm 1 is stopped, the frame 4 is pushed up, and when the elevator 2 is lowered, the chain 9 runs by the mechanism 11, and the bucket 10 is turned through 180 deg. to scoop up the sand.

Description

[Detailed description of the invention] The present invention relates to a sand discharge device.

The sediment in the sedimentation basin is scraped up by a packet conveyor installed inside the sedimentation basin.

However, when the sediment accumulated in the sewer pipes is washed away by heavy rain and a large amount of sediment flows into the settling basin, the carrier side of the packet conveyor is buried in the sediment.

As a result, sand cannot be raked up.

In view of the above-mentioned points, the present invention provides a sand discharge device that can discharge soil without being affected by the amount of soil flowing in.

Next, the present invention will be explained in detail based on the drawings.

In the figure, / represents the parallel arms of the left and right Miki that move up and down in synchrony.

The arm may be raised and lowered by a method such as moving the chino by the expansion and contraction of the cylinder or by the operation of the motor.

Reference numeral 2 denotes an elevating body provided at the lower end of the arms / and / so as to move up and down while using the arms / as a guide.

The elevating body 2 consists of a rectangular frame, and both sides of the elevating body are fitted into groove-shaped paulownia arms to guide the elevating body.
The lifting and lowering may follow the lifting and lowering of the arm/, or may fall independently after the arm/ has finished lowering; for example, by the extension or contraction of the cylinder 3, or by driving the chino by driving the motor, etc. You can do it using this method.

3 is an elevating frame provided on the elevating body 2.

The above-mentioned elevating frame t is formed by connecting the upper ends of the left and right three groove-shaped side pillars B and O to both ends of the connecting member S, and is guided up and down by fitting the above-mentioned side pillars A and B into the elevating body. .

7.7 is a sprocket that is housed at the lower end of both sides of the elevating frame l so as to freely rotate.

Gog is a sprocket that is housed in the upper part of both sides of the elevating frame t so that it can rotate freely.

7.9 is each upper and lower sprocket g, 7 and g.

It's an endless cheno that goes all the way to 7.

10 is a packet provided to rotate together with the lower sprocket 7.7.

// is a reversal prevention mechanism that causes the center wheel to move as the elevating body 2 descends.

In the case shown in the figure, the above-mentioned reversal prevention @ structure attaches the plate-shaped body /3 to the elevating body 2 via a pin /2 so as to be rotatable, and /
The downward tip of the plate-shaped body /3 is brought into contact with the stopper /l of the elevating body 2 using a screw or its own weight, and the elevating body 2 is lowered.
When it starts, the tip of the plate-shaped body /3 collides with the pin /B connecting the link /3 of the centerer, causing the changer to run.

In the figure, 77 is a stopper provided on the elevating frame 1I-iC.

The discharging device of Zero Starter 1 is as shown in L below, and the method for discharging the sediment will now be explained.

The arm is lowered into the settling basin.

When the sprocket 7 reaches the settled sand, the arm stops descending.

The sprocket 7 is placed in the sand when the arm stops descending at 11.
When it reaches, push up the lifting frame.

It will be done.

After that, when the elevating body 2 is lowered, the reversal prevention device 1 (if
/ Since Cheno 7 moves (in the direction of the arrow in Figure 2) by /, packet 10 rotates /g00, 1, +
i+', packet 10, 1. SurAi l? 1 no or J
-<I'm sorry. .

After scooping up the sediment, the arm is raised and the packet 10 is moved to the soil removal location, and then the lifting body 2 is moved.
While descending, the packet 10 is moved /gO11!1 to discharge the sediment.

Note that the elevating body is raised before the arm is lowered.

At this time, the reversal prevention mechanism // does not act on the centerer, so the centerer does not run.

As mentioned above, when the packet reaches the settling sand,
The packet is rotated /g00 times to scoop up the sediment, so
Even a sudden increase in sediment can be scooped out without any effect.

[Brief explanation of the drawing]

Fig. 1 is a front view, Fig. 2 is a side view, and Fig. 3 is a longitudinal cross-sectional view showing the movement of the cheno.

Claims (1)

[Claims] An elevating body is provided between the lower ends of the two parallel elevating arms, and the elevating body is moved up and down using the arm as a guide, and the elevating body is provided with an elevating frame that is moved up and down using the elevating body described in 1. as a guide. A sprocket is provided on the top and bottom, and a chain is passed between the upper and lower sprockets, and a packet is provided between the downward facing sprockets to rotate with the sprocket, and a reversal mechanism is provided in which the lifting body runs through the chain when the lifting body is lowered. This sand settling device is characterized by having a prevention mechanism and lowering the elevating body when the packet reaches the sand settling area.
