Description

Technical Field

[0001] This utility model relates to the field of sand suction equipment technology, and in particular to a drilling-type sand suction drill bit. Background Technology

[0002] The drilling-type sand suction bit is a key component used in sand suction operations. It is usually installed on drilling equipment or sand suction vessels. When working, the drilling-type sand suction bit rotates and cuts into the sand layer. At the same time, it uses the sand suction pipe inside the drilling-type sand suction bit to suck in the sand and transport it out, providing strong support for sand suction operations. It plays an important role in mining, water conservancy and other related fields.

[0003] However, existing sand-absorbing drill bits involve hollowing out the front end of the drill bit before drilling into deep sand layers. Then, a sand-absorbing pump is activated to extract sand from the gaps in the drill bit and bring it above the water surface. Because of the hollowed-out structure at the front end, this type of sand-absorbing drill bit suffers from low strength and a small suction area. Furthermore, the small suction area, concentrated only at the front end, results in low suction efficiency, causing the equipment to operate continuously and consuming a large amount of energy. This leads to energy waste and a significant increase in company costs, failing to meet actual usage requirements. Therefore, this utility model provides a drilling-type sand-absorbing drill bit. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drilling-type sand suction drill bit.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A drilling-type sand suction drill bit, comprising:

[0007] A first sleeve, with a second sleeve slidably connected inside the first sleeve;

[0008] Two lifting components, wherein the fixed end of the lifting component is fixedly connected to the inner wall of the first sleeve, and the telescopic end of the lifting component is fixedly connected to the inner wall of the second sleeve;

[0009] The drill bit is located on the lower surface of the second sleeve. Four high-pressure water pipes are fixedly connected to the upper end of the drill bit. A water outlet is opened at the end of the high-pressure water pipe near the drill bit. Multiple circular fixing plates are fixedly connected to the outer wall of the high-pressure water pipe. The circular fixing plates are located inside the second sleeve.

[0010] The rotating rod is fixedly connected to the circular fixing plate;

[0011] A sand suction pipe, which penetrates a circular fixed plate and is fixedly connected to the circular fixed plate;

[0012] The rotating rod, sand suction pipe, and high-pressure water pipe are all located inside the first and second sleeves.

[0013] As a further description of the above technical solution:

[0014] The lifting assembly includes a first fixing plate, which is fixedly connected to the inner wall of the first sleeve. An electric push rod is fixedly connected to the first fixing plate. A second fixing plate is fixedly connected to the inner wall of the second sleeve. The telescopic end of the electric push rod is fixedly connected to the second fixing plate.

[0015] As a further description of the above technical solution:

[0016] The gap between the sand suction pipe and the drill bit is 30cm.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the drill bit is fixedly connected with multiple annular blades, which are designed to be two layers thick.

[0019] As a further description of the above technical solution:

[0020] The four high-pressure water pipes are arranged in a rectangular pattern.

[0021] As a further description of the above technical solution:

[0022] A coarse filter screen is fixedly connected to the sand suction port of the sand suction pipe.

[0023] The beneficial effects of this utility model are:

[0024] 1. Compared with existing technologies, when the sand suction drill bit reaches the designated area, the second sleeve can be moved upward by the lifting component inside the sand suction drill bit, thereby exposing the sand suction port of the sand suction pipe and the water outlet of the high-pressure water pipe. This increases the sand suction area of ​​the sand suction drill bit. Then, by starting the externally connected water pump, water is flushed out from the water outlet of the high-pressure water pipe, causing the surrounding sand to disperse. Finally, the external sand pump is started to extract the sand from the sand suction pipe, thereby reducing energy consumption and company costs, and meeting actual usage needs.

[0025] 2. Compared with the existing technology, when it is necessary to move the second sleeve upward, the telescopic end of the electric push rod in the lifting assembly can be controlled to move, so that the second sleeve connected to the telescopic end of the electric push rod moves with the telescopic end of the electric push rod. This achieves control over the movement of the second sleeve, allowing the sand suction port of the sand suction pipe and the water outlet of the high-pressure water pipe to be exposed.

[0035] Reference Figures 1 to 6 The present invention provides a drilling-type sand suction drill bit, comprising: a first sleeve 1, a second sleeve 2, two lifting components 5, a drill bit 3, a rotating rod 7, and a sand suction pipe 8.

[0036] The first sleeve 1 is internally slidably connected to the second sleeve 2. The fixed end of the lifting assembly 5 is fixedly connected to the inner wall of the first sleeve 1, and the telescopic end of the lifting assembly 5 is fixedly connected to the inner wall of the second sleeve 2. The upper end of the first sleeve 1 is fixedly connected to the suspension device in the drilling and sand suction equipment. By controlling the lifting assembly 5, the second sleeve 2 can be raised or lowered. The drill bit 3 is located on the lower surface of the second sleeve 2. Four high-pressure water pipes 6 are fixedly connected to the upper end of the drill bit 3. A water outlet 9 is opened at the end of the high-pressure water pipe 6 near the drill bit 3. The sand can be dispersed through the high-pressure water pipes 6. Multiple circular... The circular fixing plate 10 is located inside the second sleeve 2. The circular fixing plate 10, which is connected to the high-pressure water pipe 6, makes the high-pressure water pipe 6 and the sand suction pipe 8 more stable during operation. The rotating rod 7 is fixedly connected to the circular fixing plate 10. The output end of the external motor is connected to the rotating rod 7, which makes the sand suction drill bit rotate. The sand suction pipe 8 passes through the circular fixing plate 10 and is fixedly connected to the circular fixing plate 10. The external sand suction pump is connected to the sand suction pipe 8 to extract sand. The rotating rod 7, the sand suction pipe 8 and the high-pressure water pipe 6 are all located inside the first sleeve 1 and the second sleeve 2.

[0037] Specifically, the lifting assembly 5 inside the first sleeve 1 and the second sleeve 2 controls the rise of the second sleeve 2, exposing the sand suction port of the sand suction pipe 8 and the water outlet 9 inside the second sleeve 2, thereby increasing the sand suction area of ​​the sand suction drill bit. Then, the externally connected water pump is started to flush water out from the water outlet 9, causing the surrounding sand to disperse. Then, the external sand suction pump is started to extract the sand from the sand suction pipe 8. Furthermore, since multiple circular fixing plates 10 are connected to the outer wall of the high-pressure water pipe 6, the high-pressure water pipe 6 and the sand suction pipe 8 are more stable during operation.

[0038] In one embodiment, the lifting assembly 5 includes a first fixed plate 501, which is fixedly connected to the inner wall of the first sleeve 1. An electric push rod 502 is fixedly connected to the first fixed plate 501. A second fixed plate 503 is fixedly connected to the inner wall of the second sleeve 2. The telescopic end of the electric push rod 502 is fixedly connected to the second fixed plate 503. By controlling the telescopic end of the electric push rod 502 to move, the second fixed plate 503 connected to the telescopic end of the electric push rod 502 moves along with it. At the same time, the second sleeve 2 connected to the second fixed plate 503 also moves along with it, thereby exposing the sand suction port of the sand suction pipe 8 and the water outlet 9 on the high-pressure water pipe 6.

[0039] In one embodiment, the gap between the sand suction pipe 8 and the drill bit 3 is 30cm. By setting the gap between the sand suction pipe 8 and the drill bit 3 to 30cm, the sand suction pipe 8 can have sufficient space to perform sand suction work.

[0040] In one embodiment, a plurality of annular blades 4 are fixedly connected to the outer wall of the drill bit 3. The annular blades 4 are designed in two layers. By designing the annular blades 4 in two layers, the sand-absorbing drill bit can break through the hard materials it encounters during the drilling process, which facilitates the efficient completion of the drilling work.

[0041] In one embodiment, the four high-pressure water pipes 6 are arranged in a rectangular pattern. By designing the high-pressure water pipes 6 in a rectangular pattern, sand can be flushed more quickly to the vicinity of the sand suction pipe 8.

[0042] In one embodiment, a coarse filter screen 11 is fixedly connected to the sand suction port of the sand suction pipe 8. By installing the coarse filter screen 11 at the sand suction port of the sand suction pipe 8, larger impurities can be effectively prevented from entering the external sand suction pump from the sand suction pipe 8, thereby damaging the pump body.
