AI Technical Summary
In the existing pile machine technology, the inadequate discharge of mud will cause the subsequent mud to be removed from the drill rod to be unable to be disconnected in time, affecting the efficiency of mud discharge and drilling. At the same time, the mud will spread to the ground, causing the ground to be soft and muddy.
A high-efficiency mud discharge device is designed, including a frame, a first row of mud pipes, a stirring shaft and a lifting cylinder. The first row of mud pipes is fixed on the outer wall of the frame, with rotating shafts and spiral blades inside, and the stirring shaft rotates on both sides of the frame inside. A lifting cylinder and slurry plate are installed outside the frame. The lifting cylinder lifts mud and scatters on the slurry plate to prevent mud from directly reaching the ground.
By lifting the design of the cylinder and slurry plate, mud is avoided to scatter directly on the ground, preventing the water from spreading, maintaining the dryness of the operating ground, and improving the efficiency of mud removal.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile drivers, and particularly relates to an efficient mud discharging device. Background Art
[0002] During the repeated advancing and retracting process of the drill pipe of a pile driver, mud will be carried out, and it is necessary to discharge the mud in time. Otherwise, the sediment subsequently carried out by the drill pipe cannot be separated from the drill pipe in time, and the mud will return to the drilling hole again along with the feeding of the drill pipe, affecting the mud discharge and drilling efficiency.
[0003] As Figure 1 shown, in the existing mud discharging device, generally, a mud discharging pipe 2 communicated with the inside of the frame body 1 is arranged on one end face of the frame body, and stirring shafts 3 parallel to the mud discharging pipe are arranged on both sides of the drilling center inside the frame body. The large pieces of mud and stones carried out by the drill pipe are broken by the stirring blades 4 arranged on the stirring shafts and pushed towards the mud discharging pipe for easy discharge through the mud discharging pipe. In order not to affect the advancing and retracting of the drill pipe and the falling off of the sediment on the drill pipe, a gap 5 for the sediment to fall off from the drill pipe is left between the stirring shafts and the stirring blades and the drill pipe. This also causes the mud carried out by the drill pipe to accumulate in the gap, which is not conducive to the discharge of the mud by the stirring blades. Moreover, the frame body is directly placed on the ground, and the discharged mud water will spread around along the gap between the frame body and the ground, making the ground soft and muddy, which is not conducive to equipment operation and manual activities.
[0004] To solve the above problems, this case is thus generated. Content of the Utility Model
[0005] Therefore, in view of the above problems, the utility model provides an efficient mud discharging device.
[0006] To solve the above technical problems, the solution adopted by the present utility model is as follows: An efficient mud discharging device, comprising a frame body, a first mud discharging pipe, and a stirring shaft. The first mud discharging pipe is fixedly arranged on the outer wall of the frame body and is fixed to the frame body. A rotating shaft is arranged inside the first mud discharging pipe, and a first spiral blade is wound around the rotating shaft. A first rotation driving member for driving the rotation of the rotating shaft is arranged at the free end of the first mud discharging pipe. At least one discharge interface is arranged at the free end of the first mud discharging pipe. The stirring shaft is rotatably arranged on both sides inside the frame body, and stirring blades are evenly distributed on the stirring shaft. A second rotation driving member for driving the rotation of the stirring shaft is arranged outside the frame body. Second mud discharging pipes parallel to the first mud discharging pipe are respectively and fixedly arranged on both sides of the first mud discharging pipe on the outer wall of the frame body. The fixed port of the second mud discharging pipe penetrates through the frame body and extends to the inside of the frame body. The housing of the second rotation driving member is fixedly arranged at the free end of the second mud discharging pipe. One end of the stirring shaft is rotatably arranged on the inner wall of the frame body, and the other end passes through the inside of the second mud discharging pipe and is rotatably arranged on the free end surface of the second mud discharging pipe. A connecting pipe is arranged between the second mud discharging pipe and the first mud discharging pipe. One end of the connecting pipe is communicated and arranged at the free end of the second mud discharging pipe, and the other end is communicated and arranged at the fixed end of the first mud discharging pipe. A lifting cylinder for increasing the scattering height of the mud drilled out by the external drill pipe is arranged in the middle of the frame body. A slurry receiving plate for preventing the mud from scattering onto the ground is fixedly arranged on the outer wall of the upper end of the lifting cylinder. The two sides of the slurry receiving plate gradually decrease in height towards the lower part of the stirring shaft. The periphery of the slurry receiving plate is hermetically and fixedly connected to the inner wall of the frame body.
[0007] Further improvement is: A second spiral blade is fixedly wound around the outer wall of the stirring shaft inside the second mud discharging pipe.
[0008] Further improvement is: A first mounting plate is arranged at the fixed end of the first mud discharging pipe, and the first mounting plate is detachably arranged on the outer wall of the frame body.
[0009] Further improvement is: A second mounting plate is integrally arranged on the outer wall of the fixed end of the second mud discharging pipe. The second mounting plate is 5 - 15 centimeters away from the fixed port of the second mud discharging pipe, and the second mounting plate is detachably arranged on the frame body.
[0010] Further improvement is: Mounting lugs for lifting and lowering cooperation with the chassis of the external pile driver are respectively arranged at the four corners of the outer wall of the frame body.
[0011] Further improvement is: An insertion part for inserting into the ground to limit the spread of water is arranged at the lower end of the frame body. The lower port of the lifting cylinder and the lower port of the insertion part are on the same horizontal plane.
[0012] Further improvements are as follows: positioning pieces are longitudinally arranged along both sides of the slurry receiving plate, and a number of positioning members are arranged between the positioning pieces and the frame body.
[0013] Further improvements are as follows: the positioning member is a bolt.
[0014] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:
[0015] In this case, a lifting cylinder and a slurry receiving plate are provided. The lifting cylinder lifts the slurry discharged by the drill pipe, so that the slurry is scattered on the slurry receiving plate instead of directly on the ground, avoiding the water body from spreading around through the frame body, which is beneficial to maintaining the dryness of the operation ground for convenient equipment operation and manual activities. At the same time, the downward inclination on both sides of the slurry receiving plate is beneficial to the direct scattering of the slurry onto the stirring shaft, avoiding the accumulation of the slurry and improving the slurry discharge efficiency.
[0016] In order to adapt to the inclined installation on both sides of the slurry receiving plate and avoid interference between the slurry receiving plate and the first mud discharge pipe, a second mud discharge pipe and a connecting pipe are provided in this case. The slurry is first discharged into the second mud discharge pipe outside the frame body, and under the pumping action of the internal rotating shaft and the first spiral blade in the first mud discharge pipe, the slurry enters the first mud discharge pipe along the connecting pipe.
[0017] A further beneficial effect is that a second spiral blade is wound and welded on the outer wall of the stirring shaft in the second mud discharge pipe, making reasonable use of the rotation of the stirring shaft to facilitate the active entry of the slurry into the connecting channel and improving the slurry discharge efficiency.
[0018] A further beneficial effect is that the setting of the first mounting plate and the second mounting plate enables the first mud discharge pipe and the second mud discharge pipe to be disassembled and assembled as a whole, facilitating the assembly of components.
[0019] A further beneficial effect is that the inserted part provided at the lower end of the frame body further hinders the water body from spreading to the ground.
[0020] A further beneficial effect is that the slurry receiving plate is fixedly connected to the outer wall of the lifting cylinder and the inner wall of the frame body by welding. The slurry receiving plate is first positioned and installed inside the frame body through the positioning piece and the bolt, so as to facilitate the welding connection between the slurry receiving plate and the inner wall of the frame body. The lower port of the lifting cylinder is flush with the lower port of the frame body. When welding the lifting cylinder, the lifting cylinder can be directly placed in the installation opening dug in the middle of the slurry receiving plate and then welded, improving the welding efficiency between components.
