Description

Technical Field

[0001] This utility model relates to the field of double-bottom sand scooping equipment, and in particular to a double-bottom sand scooping device. Background Technology

[0002] In construction engineering, rotary drilling rigs are commonly used for soil sampling or drilling operations. Double-bottom sand scooping buckets are a common type of drill bit. However, some problems exist during the use of double-bottom sand scooping buckets. After use, the hinged double-bottom drill plate is opened to discharge the soil collected in the rotary drilling sleeve. However, some clumps of soil remain on the top inner wall of the rotary drilling sleeve, making it difficult to remove. This soil occupies part of the volume inside the rotary drilling sleeve, affecting the next operation of the double-bottom sand scooping bucket. Therefore, to address the problem of clumps of soil residue, this utility model proposes a double-bottom sand scooping bucket. Utility Model Content

[0003] The purpose of this invention is to provide a double-bottom sand scoop to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-bottom sand dredging bucket, comprising a rotary drill sleeve, and further comprising:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 The double-bottom sand dredging bucket shown includes a rotary drill sleeve 1, as well as a lowering drill assembly and a water injection assembly 5;

[0023] Specifically, the down-drilling assembly is used for drilling deeper into the rotary drilling sleeve 1. The down-drilling assembly includes a double bottom drill plate 2, the sides of which are hinged to the bottom sides of the rotary drilling sleeve 1. The top of the rotary drilling sleeve 1 is provided with a connecting part for connecting the drill rod of the drilling rig.

[0024] It should be noted that a pressure relief hole 3 is provided on the outside of the rotary drill sleeve 1. The pressure relief hole 3 is used to assist in the discharge of soil in the rotary drill sleeve 1. The connecting part includes a fixed sleeve 4 provided on the top of the rotary drill sleeve 1. A pin hole is provided on the side of the fixed sleeve 4. The pin hole is used to fix the drill rod to the fixed sleeve 4.

[0025] Specifically, the fixed sleeve 4 and the rotary drill sleeve 1 are fixed by welding. The working principle of the whole assembly of the rotary drill sleeve 1 and the double bottom drill plate 2 is referenced to the SD100 type double bottom sand scooping bucket.

[0026] Specifically, the water injection component 5 is used to generate a jet to discharge soil in the rotary drilling sleeve 1. The water injection component 5 includes a water injection pipe 501 that is inserted and connected to the top side of the rotary drilling sleeve 1. A movable sleeve 502 is inserted and connected to the side of the water injection pipe 501 and located in the inner cavity of the rotary drilling sleeve 1. A drain section for high-pressure water discharge is provided on the outside of the movable sleeve 502.

[0027] It should be noted that the water injection pipe 501 and the rotary drill sleeve 1 are fixed by welding at the insertion point. The movable sleeve 502 is made of steel. The drainage part includes multiple sets of water spray holes 505 that are opened around the outside of the movable sleeve 502. The outside of the water injection pipe 501 is provided with a blocking component to prevent soil from entering the water spray holes 505.

[0028] Specifically, the blocking component includes a hidden sleeve 503 located outside the water injection pipe 501. The hidden sleeve 503 is sleeved on the outside of the movable sleeve 502. The hidden sleeve 503 is fixed to the water injection pipe 501 by welding. The water spray hole 505 can enter the middle of the hidden sleeve 503 to prevent soil from entering the water spray hole 505 during the rotary drilling process.

[0029] One end of the movable sleeve 502 and inside the water injection pipe 501 is provided with a limiting part for limiting the movable sleeve 502, and a spring-loaded part for moving and resetting the movable sleeve 502 is provided on the side of the limiting part.

[0030] Specifically, the limiting part includes a positioning ring 504, the middle part of which is fixedly connected to the outer side of the movable sleeve 502. The rebound part is provided in the inner cavity of the water injection pipe 501 and located on the side of the movable sleeve 502. The rebound part includes an elastic ring 506, which is sleeved on the outer side of the movable sleeve 502.

[0031] It should be noted that the side of the water injection pipe 501 is provided with a cylindrical hole for the movable sleeve 502 to pass through. The positioning ring 504 is welded and fixed to the movable sleeve 502. The elastic ring 506 is made of rubber. The elastic ring 506 is glued and fixed to the outside of the movable sleeve 502. When the elastic ring 506 is not squeezed, the water spray hole 505 is located in the middle of the hidden sleeve 503.

[0032] Specifically, the end of the movable sleeve 502 away from the water injection pipe 501 is provided with an annular protrusion. The annular protrusion is used to limit the insertion of the movable sleeve 502 and the hidden sleeve 503, so as to prevent the movable sleeve 502 from completely entering the middle of the hidden sleeve 503.

[0033] In actual use, the staff connects the high-pressure water source to the water injection pipe 501. The water pressure pushes the movable sleeve 502, which is inserted into the side of the water injection pipe 501, to move, squeezing the elastic ring 506. The water spray hole 505 moves out of the hidden sleeve 503, and the high-pressure water jet is discharged through the water spray hole 505 on the outside of the movable sleeve 502. The high-pressure jet washes away the clumps of soil remaining on the inner wall of the rotary drilling sleeve 1. After the washing is completed, the elastic ring 506 pushes the movable sleeve 502 to reset. This design can prevent the clumps of soil from affecting the subsequent drilling operations of the rotary drilling sleeve 1.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
