AI Technical Summary
In existing vertical shaft construction, debris removal is not thorough, the front-end load is too heavy, and a large space is occupied, which affects the layout and steering ability of construction machinery. In addition, it is difficult to effectively remove debris in areas with special geological conditions or water scarcity, resulting in low construction continuity and efficiency.
A vacuum centrifugal pump is used in combination with a polymerization pipe and a main slag discharge pipe. The slag is sucked into the polymerization pipe through a bucket and then transported out of the shaft through the main slag discharge pipe. The negative pressure of the vacuum centrifugal pump is used to achieve rapid transportation of the slag.
The timely and rapid removal of debris was achieved, which improved the continuity and efficiency of construction and reduced the number of pauses for debris removal during construction.

Abstract
Description
Technical Field
[0001] The invention discloses a slag discharge device for a shaft boring machine, and relates to the manufacturing field of shaft boring machines, in particular to a slag discharge device for a shaft boring machine. Background Art
[0002] Vertical shafts play a key role in many industries, including hydropower, transportation, non-metallic mining, mining, and coal mining. Their depth and diameter depend on project requirements and geological conditions, ranging from tens of meters to thousands of meters. During the construction of vertical shafts, the removal of debris is a major challenge. At present, commonly used debris removal methods include dry debris removal methods (such as grabs, scrapers and screw conveyors) and wet debris removal methods (mud and water circulation and other technologies). However, the dry debris removal method has some shortcomings, such as incomplete removal, heavy front-end load and large space occupation, which affect the layout and steering capabilities of construction machinery; in areas with special geological conditions or scarce water resources, the wet debris removal method is difficult to implement.
[0003] In short, during shaft construction, due to the large amount of excavated debris, the ability to remove the debris is limited, and the debris generated by excavation cannot be discharged quickly and effectively. This causes the debris to accumulate in the construction area, and construction needs to be suspended from time to time for debris removal, thus affecting the continuity and efficiency of construction. Utility Model Content
[0004] The problem to be solved by this utility model is to provide a slag discharge device for a roadheader that can promptly and quickly transport slag out of the shaft in order to address the above shortcomings. The technical solution is as follows:
[0005] A slag discharge device for a shaft boring machine includes a cutterhead, a cutter wheel and a bucket, with a closed end at the rear end of the bucket. The key technology is to open a hole at the position corresponding to the bucket on the cutterhead and install a vacuum centrifugal pump through a connecting pipe. The pipeline of the vacuum centrifugal pump is connected to a polymer pipe, and the middle position of the polymer pipe is connected to the main slag discharge pipe through a rotary joint.
[0006] There are two buckets, which are symmetrically arranged along the center of the cutter head.
[0007] The two ends of the polymerization tube are respectively connected to the pipelines of the vacuum centrifugal pump to form an X-shaped pipeline.
[0008] The main slag discharge pipe is made of a rubber tube.
[0009] The bucket entrance is provided with an extended side with a slope.
[0010] The slope of the extended side is 10 to 12 degrees.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The vacuum centrifugal pump connected to the rear end of the bucket sucks the slag into the polymerization pipe, and then through the polymerization of the polymerization pipe, the slag is sucked into the main slag discharge pipe, and the slag is transported out of the shaft in a timely and rapid manner, greatly improving work efficiency.
[0013] 2. The double buckets symmetrically arranged along the center of the cutter disc can efficiently and quickly collect the rock and soil crushed by the cutter wheel into the bucket cavity, and cooperate with the vacuum centrifugal pump to improve work efficiency.

[0018] Reference Figures 1 to 4 A slag discharge device for a shaft boring machine includes a cutterhead 6, a cutter wheel 7, and a bucket 8. The rear end of bucket 8 is closed. The key technology is to drill a hole in the cutterhead 6 corresponding to bucket 8, install a vacuum centrifugal pump 2 through a connecting pipe 1, and connect the pipe of the vacuum centrifugal pump 2 to a polymer pipe 3 via a flange. The middle of the polymer pipe 3 is connected to the main slag discharge pipe 5 via a rotary joint 4. When the cutterhead 6 rotates, the polymer pipe 3 can rotate due to the rotary joint 4. The polymer pipe 3 and the main slag discharge pipe 5 are all sealed.
[0019] There are two buckets 8, which are symmetrically arranged along the center of the cutter head 6 by bolts.
[0020] Both ends of the polymerization tube 3 are connected to the pipelines of the vacuum centrifugal pump 2 corresponding to the bucket 8, and the polymerization tube 3 and the pipelines of the vacuum centrifugal pump 2 form a "X"-shaped pipeline.
[0021] The main slag discharge pipe 5 is made of a rubber tube.
[0022] The entrance of the bucket 8 is provided with an extended side 8.1 with a slope, so that the debris can enter the bucket 8 more smoothly.
[0023] The slope of the extended side 8.1 is 10 to 12 degrees.
[0024] During construction, the cutterhead 6 rotates, and the cutter wheel 7 breaks rocks and crushes debris in front. The bucket 8 shovels the crushed rock and soil into the bucket 8 as it follows the rotation of the cutterhead. The vacuum centrifugal pump 2 sucks the rock and soil in the bucket 8 into the polymerization pipe 3, and transports the debris (rock and soil) out of the shaft through the rotary joint 4 and the main slag discharge pipe 5.
