DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Please refer to Figure 1-Figure 3 As shown, in the embodiment of the utility model,

[0024] A water-sand mixed water jet device, comprising: a sand storage hopper 100 and a buffer box 200, the sand storage hopper 100 is connected to a cavity 210 inside the buffer box 200 through a connecting pipe 110, a sand outlet pipe 310 is provided at the bottom of the buffer box 200, and the sand outlet pipe 310 is connected to a water jet head 300 through a pipeline;

[0025] A rectangular rod 230 is inserted into the cache box 200, and a feed hole 231 is vertically opened in the middle of the rectangular rod 230. A vent hole is also opened on the rectangular rod 230. When the rectangular rod 230 slides inward and the connecting pipe 110 is connected with the rectangular rod 230, the vent hole is blocked, and the water jet sand in the sand storage hopper 100 enters the interior of the cavity 210 through the feed hole 231. When the rectangular rod 230 slides outward, the rectangular rod 230 blocks the bottom of the connecting pipe 110, and the cavity 210 is connected with the outside through the vent hole.

[0026] The vent hole includes a first hole 234, a second hole 235 and a third hole 236. The first hole 234 is inclined to the upper right and is connected to the feeding hole 231. The second hole 235 is connected to the first hole 234 and is inclined to the lower right. The third hole 236 is connected to the second hole 235 and is vertically downward. The first hole 234 is inclined to the upper right, the second hole 235 is inclined to the lower right, and the third hole 236 is vertically downward to effectively prevent water jet sand from entering the interior of the vent hole.

[0027] The top left inner wall of the cache box 200 is provided with a slot 232 for inserting the rectangular rod 230. The inside of the slot 232 into which the rectangular rod 230 is inserted improves the stability of the rectangular rod 230.

[0028] The bottom of the slot 232 is provided with a cutout 220 , which facilitates the rectangular rod 230 to be inserted into the slot 232 .

[0029] A limit block 233 is provided at the bottom of the rectangular rod 230 on the right side of the material feeding hole 231 to effectively prevent the rectangular rod 230 from escaping from the buffer box 200 .

[0030] The right end of the rectangular rod 230 is screwed with the round rod 240 , and the right end of the round rod 240 is integrally formed with a pull ring 241 , which facilitates pushing and pulling the rectangular rod 230 .

[0031] Structural principle:

[0032] like Figure 2 As shown, the rectangular rod 230 is pushed inwards so that the connecting pipe 110 is connected to the rectangular rod 230, and the water jet sand in the sand storage hopper 100 falls into the interior of the cavity 210. When in use, the sand outlet pipe 310 is connected to the water jet head 300 through a pipeline. Under the negative pressure generated by the water jet head 300, the water jet sand in the cavity 210 is sucked into the interior of the water jet head 300, so that the water and sand are mixed;

[0033] like Figure 1 and Figure 3 As shown, after the cutting is completed, the rectangular rod 230 is pulled outward, and the rectangular rod 230 blocks the bottom of the connecting pipe 110. The cavity 210 is connected to the outside through the vent hole. After the water jet sand inside the cavity 210 is sucked out, the high-pressure water supply pump of the water jet head 300 is turned off, so that no water jet sand will remain in the water jet head 300, and the water jet head 300 will not be blocked. Only the rectangular rod 230 needs to be pushed and pulled to control the connection between the cavity 210 and the connecting pipe 110 or the external air, so as to facilitate the discharge of the water jet sand inside the cavity 210. It is an integrated two-control system with simple operation.

[0034] The above description shows and describes several preferred embodiments of the utility model, but as before, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept of this article through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
