Sand replenishment device for sand dredging equipment

Abstract

A sand replenishment device for a sand pumping machine includes an input connector for connecting to a sand pumping pipe, an output connector for connecting to a sand conveying pipe, a sand replenishment frame located above the output connector, and a connecting pipe. The sand replenishment frame has a bucket body with a sand replenishment channel communicating with the output connector. The connecting pipe connects the sand replenishment channel and the input connector. The sand and water pumped by the sand pumping pipe can enter the sand replenishment channel through the input connector and the connecting pipe, and the sand and soil can be poured into the bucket body to mix with the sand and water pumped by the sand pumping pipe.

Claims

1. A sand replenishment device for a sand pumping machine, comprising: an input connector for connection to a sand pumping pipe; an output connector for connection to a sand conveying pipe; a sand replenishment frame located above the output connector and having a bucket body having a sand replenishment channel communicating with the output connector; and a connecting pipe connecting the input connector and the sand replenishment channel.

2. The sand replenishment device for a sand pumping machine as described in claim 1, wherein the sand replenishment frame includes a pipe extending into the sand replenishment channel and connected to the input connector via the connecting pipe, the pipe including at least one outlet.

3. The sand replenishment device for a sand pumping machine as described in claim 2, wherein the connecting pipe is provided with a valve body that can open or close the connecting pipe.

4. The sand replenishment device for a sand pumping machine as described in claim 3, wherein the pipe includes a first branch extending downward along the sand replenishment channel, and the first branch has a plurality of said outlets arranged at intervals.

5. The sand replenishment device for a sand pumping machine as described in claim 4, wherein the pipe includes a second branch pipe connected to the bottom end of the first branch pipe and extending laterally, the second branch pipe having a plurality of said outlets arranged laterally at intervals.

6. A sand replenishment device for a sand pumping machine as described in any one of claims 1 to 5, wherein the sand replenishment channel gradually narrows downwards.

7. The sand replenishment device for a sand dredging machine as described in claim 6, wherein the output connector is connected to the top of a main body, the sand replenishment frame is connected to the top of the main body, and the input connector is connected to the side of the main body.
