Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traveling sand pumping device for pumping sand from a sand settling pond.

BACKGROUND ART Conventionally, a traveling sand pumping device comprising a traveling truck equipped with a packet elevator has been used to lift sand from a sand settling pond.

However, since conventional packet elevators rotate V-shaped packets in one direction, sand can only be lifted when the trolley is traveling in one direction, and if multiple trips are required, the elevator cannot lift sand in the opposite direction. The sand pumping work was time-consuming and troublesome, as the traveling time was wasted.

The present invention provides a traveling type sand lifting device that can lift sand during both reciprocating travel, and one embodiment thereof will be described below with reference to the drawings.

1 is a sand settling basin, and a plurality of sand settling basins 1 are provided in parallel with partition walls 2 interposed therebetween.

Rails 3 are laid along the upper edges of the side walls of the sand settling basins 1 at both ends, and a traveling carriage 4 extending over each settling basin 1 is installed on the rails 3 so as to be able to run.

It has a self-propelled device with four traveling trolleys.

A traveling truck 4 is provided with a rail 5 extending in the transverse direction of the sand settling basin 1, and a traversing truck 7 having a self-propelled device 6 is installed on the rail 5.

It is an 8-wheel drive cab.

The traversing truck 7 is provided with a packet conveyor 9 whose lower end reaches the bottom of the sand settling basin 1.

It has an endless rotating body 14, such as a chain, which is hung around the packet conveyor 9/li driving sprocket 10 and guide sprockets 11-13.

The endless rotating body 14 is driven by the scraping motor 25 via the drive sprocket 10 to perform forward and reverse rotation.

15 is a guide.

A pair of endless rotating bodies 14 are arranged in parallel,
Packets 16 are attached between both endless rotating bodies 14 at appropriate intervals in the longitudinal direction.

The packet 16 has a pair of accommodating recesses 17a and 17b whose openings are located in opposite directions, and the accommodating recesses 17a and 17b open in the longitudinal direction of the endless rotating body 14.

The drive sprocket 10 and sprocket 12 are
It is arranged laterally from the vertical rotation path portion 14a of the endless rotating body 14, and there is a sand discharge position P1 where the packet 16 is reversed when the endless rotating body 14 is rotated forward and a sand discharge position P1 when the packet 16 is reversed. The sand position P2 is the vertical rotation path portion 14a.
It is located on the same side as the

A chute 18 extends below these sand discharge positions P1 and P2.
The chute 18 opens onto a flight conveyor 19 provided in the width direction of the traveling carriage 4.

The lower body frame 20 to which the sprocket 13 at the lower end of the packet conveyor 9 is attached is connected to the upper body frame 21 fixed to the traversing cart 7.
It is supported via a bracket 24 so as to be movable up and down around a support shaft 22, and is rotated by a cylinder device 23 installed on the upper body frame 21.

Furthermore, the upper body frame 21 and the lower body frame 20 are provided with a guide member for guiding the endless rotating body 14 and the lower body frame 20.
A guide member is appropriately provided to prevent the endless rotating body 14 from sagging when the endless rotating body 14 is rotated upward.

Next, to explain the operation of the above configuration, the endless rotating body 14 of the packet conveyor 9 is rotated while the traveling cart 4 is running in the longitudinal direction of the settling basin 1, and the sand on the bottom of the settling basin 1 is scraped up by the packets 16. .

In this case, the packet 16 has a pair of accommodation recesses 17a and 17.
Since the openings b are located in opposite directions, by rotating the endless rotating body 14 in the forward and reverse directions, sand can be scraped up even when the traveling trolley 4 moves forward or backward. be able to.

Therefore, when the traveling trolley 4 is moved back and forth and the widthwise position of the packet conveyor 9 in the settling basin 1 is changed every time the traveling trolley 4 travels, the entire sand is lifted, and the traveling time of the traveling trolley 4 when making a return trip is wasted. Efficient sand pumping is possible.

The position of the packet conveyor 9 is changed by moving the traversing cart 7.

The sand raked up by the packet 16 is sent to the sand discharge position P1 or P.
2, the packet 16 is reversed and falls into the chute 18, causing the flight control? The fuel is discharged to the side of the traveling truck 4 via the roller 19.

As in this embodiment, the sand discharge positions P and P2 are set by the endless rotating body 1.
If the chute 18 and the flight conveyor 19 are provided close to and on the same side with respect to the vertical rotation path portion 14a of the conveyor 4, installation of the chute 18 and the flight conveyor 19 is easy.

When the packet conveyor 9 is to be transferred to the adjacent sand settling basin 1 after sand pumping in one settling basin 1 is completed, the lower body frame 20 is lifted upward from the partition wall 2 by the cylinder device 23, and the traversing cart 7 is moved.

As explained above, according to the present invention, sand can be pumped up both when the traveling truck moves forward and when it moves backward, and the sand pumping time can be shortened.
