Description

Technical Field

[0001] This invention relates to the field of deep foundation pit drilling equipment technology, specifically to a drilling equipment for ultra-deep foundation pit construction and its usage method. Background Technology

[0002] Deep foundation pits refer to excavations exceeding 5 meters in depth, or projects with particularly complex geological conditions, surrounding environment, and underground pipelines even if the depth does not exceed 5 meters. Foundation pit engineering mainly includes the design and construction of the foundation pit support system and earthwork excavation, and is a highly comprehensive and systematic project. It requires close cooperation between geotechnical and structural engineering technicians.

[0003] When drilling and trenching deep foundation pits, in order to ensure the smooth progress of the drilling and trenching operation, it is necessary to simultaneously discharge the soil and debris generated during trenching to the outside of the foundation pit to avoid clogging of the hole and affecting the continued drilling of the equipment. The traditional method of soil and debris discharge is usually to use extraction-type slag discharge. Slag extraction equipment is set up on the ground and uses negative air pressure to extract the soil and debris from the hole. Since the depth of foundation pit trenches is generally quite deep, usually more than ten meters, the load on the slag extraction equipment is high. The deeper the hole, the more likely it is that the suction is insufficient to completely extract the soil and debris. In addition, the distribution of soil and debris in the hole is relatively scattered, making it impossible to achieve a very comprehensive slag extraction operation. Furthermore, the density and volume of soil and debris vary. Soil and debris with higher hardness and larger volume are prone to clogging the channels of the slag extraction equipment during the slag extraction process. Summary of the Invention

[0012] Preferably, the method of using the drilling equipment for ultra-deep foundation pit construction includes the following steps:

[0013] S1: First, this equipment is installed on the output end of the trenching machine. The trenching machine controls this equipment to go deep underground to perform drilling operations. The top slag extraction port of the slag extraction treatment box is connected to a slag extraction pipe, and an external slag extraction device is installed. The slag extraction device can pump the soil and slag in the hole to the outside of the hole through the slag extraction pipe. First, the external trenching machine drives the trenching rollers on the two trenching components to contact the ground. Some of the trenching rollers near the slag extraction treatment box are located in the arc-shaped groove. The first motor is controlled to work, driving the first gear to rotate and then driving the second gear to rotate. This causes the toothed rotating sleeve to rotate along its outer side. With the cooperation of the two first motors, the two rotating sleeves rotate synchronously and in opposite directions, both rotating towards the slag extraction box. This causes several grooving rollers installed on the outer side of one rotating sleeve to rotate counterclockwise, and several grooving rollers installed on the outer side of the other rotating sleeve to rotate clockwise. This process drills and grooves the ground, gradually digging deeper into the ground with the help of the grooving machine. The soil and debris generated during drilling gradually gather between the two grooving rollers according to the rotation direction of the two rotating sleeves and fall into the receiving groove set on the grooving roller. During the rotation, when the grooving roller rotates to the arc-shaped groove, the soil and debris fall into the arc-shaped groove under the action of gravity because the bottom of the receiving groove is inclined. It then enters the slag extraction box through the inlet at the bottom of the arc-shaped groove for subsequent slag extraction processing.

[0014] S2: The soil and debris generated during drilling enter the slag extraction and processing box through two inlets, falling onto the first and second augers. By controlling two dual-shaft motors, the second and first drive wheels rotate, driving two conveyor belts synchronously towards the slag extraction port at the top of the slag extraction and processing box. Simultaneously, the two linked pulleys and their mating belts drive the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, causing the first and second augers to rotate synchronously. This transports the soil and debris falling onto them upwards. After the soil and debris are transported to the bottom of the first or second auger and pass through the through-hole on the discharge mounting plate, they naturally fall onto the discharge mounting plate located at the first auger. The portion of soil and debris between the first and second augers, falling onto the ends of the discharge mounting plate, is returned to the first or second auger via the ramps on both sides, until it lands on the top of the discharge mounting plate between the first and second augers. Simultaneously, as the two conveyor belts move synchronously towards the slag extraction port at the top of the slag extraction box, several shovels on the two conveyor belts scoop up the soil and debris on the discharge mounting plate and transport it upwards between the two conveyor belts. During the transport process, the shovels on the two conveyor belts exert a compressive force on the soil and debris, thereby achieving the simultaneous transport and crushing of the soil and debris towards the slag extraction port. After the soil and debris are transported to the slag extraction port, they are discharged to the outside of the borehole by the suction generated by the slag extraction port.

[0015] S3: During the upward conveying of soil and slag by the first or second auger, soil and slag located between or on either side of the bottom of the first or second auger can also be conveyed. To increase the conveying capacity, the outer trigger block synchronously rotates during its rotation, contacting the linkage plate. The linkage plate squeezes the trigger block, causing it to slide inward towards the first or second auger, which in turn drives the toothed rod to slide, thereby driving the drive gear to rotate counterclockwise. The counterclockwise rotation of the connecting rod drives the arc-shaped rod to slide along an arc-shaped trajectory towards the first or second auger. On the outside, when the trigger block disengages from the linkage plate, the reset spring resets and drives the trigger block to reset, sliding to the outside of the first or second auger. This causes the arc-shaped rod to slide along an arc-shaped trajectory to the inside of the first or second auger. Through the trajectory of the arc-shaped rod, while the first or second auger is conveying soil and slag, soil and slag at its end can be gathered together, bringing the soil and slag on the outside closer to the first or second auger. This helps to increase the soil and slag conveying range of the first or second auger and further increase its conveying capacity.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In use, this device is first installed on the output end of the trenching machine. The trenching machine controls the device to penetrate deep into the ground for drilling operations. A slag extraction pipe is connected to the top of the slag extraction treatment box, and external slag extraction equipment is installed. This equipment pumps the soil and debris from the hole out through the slag extraction pipe. Initially, two deep-pit trenching soil and debris gathering devices are controlled to rotate synchronously in opposite directions. With the cooperation of the trenching machine, the device gradually penetrates deeper into the ground for drilling. During drilling, the soil and debris gathering devices collect the soil and debris generated in the drilling pit and bring it into the slag extraction treatment box. As the soil and debris enter the box, the soil inside is... The slag conveying and crushing device operates by transporting the slag towards the slag extraction port at the top of the slag extraction and processing box. During the conveying process, the slag is crushed. After being transported to the slag extraction port, it is discharged to the outside of the borehole by the suction force generated by the slag extraction port. This avoids the problem of slag blockage caused by excessively large slag during the slag extraction process. Furthermore, by collecting and concentrating the slag, the slag extraction end of the slag extraction equipment only needs to focus on one point, avoiding the problem of slag scattering everywhere and resulting in an incomplete slag extraction range. This device achieves the effect of collecting and concentrating the slag generated during drilling, so as to facilitate the complete discharge of slag, and the slag will not block the slag discharge pipe during the discharge process.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 16 The present invention provides a technical solution comprising a slag extraction and processing box 1, which is vertically arranged on a horizontal plane. A slag extraction port 2 is provided at the middle of the top of the slag extraction and processing box 1. Two connecting frames 3 are symmetrically arranged on both sides of the slag extraction and processing box 1. A deep pit trenching soil and slag gathering device 4 is provided at the bottom of each connecting frame 3, and the two deep pit trenching soil and slag gathering devices 4 are symmetrically arranged. The lower end of the two deep pit trenching soil and slag gathering devices 4 is lower than the lower end of the slag extraction and processing box 1. A soil and slag conveying and crushing device 7 is provided inside the slag extraction and processing box 1.

[0037] In this embodiment, as Figures 2 to 8 As shown, each of the deep pit trenching soil and debris gathering devices 4 includes a mounting bracket 41, a drive assembly 42, and a trenching assembly 43. The mounting bracket 41 is cylindrical and hollow. The two center points of the mounting bracket 41 are fixedly connected to the two sides of the bottom of the connecting frame 3, respectively. The drive assembly 42 is located inside the mounting bracket 41, and the trenching assembly 43 is located outside the mounting bracket 41. The drive assembly 42 includes a first motor 421, a first gear 422, and a second gear 423. The first motor 421 is horizontally located inside the mounting bracket 41. The first gear 422 is located on the output end of the first motor 421. The second gear 423 is located above the first gear 422 and is rotatably connected to one side of the mounting bracket 41 by a shaft. The second gear 423 meshes with the first gear 422. The middle of the outer side of the mounting bracket 41 is through-hole, and the position of the second gear 423 corresponds to the through-hole of the mounting bracket 41.

[0038] The grooving assembly 43 includes a rotating sleeve 431 and grooving rollers 432. The rotating sleeve 431 is circularly arranged, and a ring of teeth 433 is provided on the inner side of the rotating sleeve 431. The rotating sleeve 431 is located on the outer side of the mounting bracket 41 and rotates with the mounting bracket 41 along the outer side of the mounting bracket 41. The teeth 433 on the inner side of the rotating sleeve 431 pass through the through-hole of the mounting bracket 41 and mesh with the second gear 423. A plurality of grooving rollers 432 are evenly arranged in a circular shape on the outer side of the rotating sleeve 431. Each grooving roller 432 has a receiving groove 434 at its top end, and the receiving groove 434 is inclined. The height of the end of the receiving groove 434 near the rotating sleeve 431 is higher than the height of the end away from the rotating sleeve 431. Baffles 435 are provided on both sides of the receiving groove 434. A plurality of grooving cones 436 are provided at the end of each grooving roller 432 away from the rotating sleeve 431.

[0039] Both sides of the slag extraction and treatment box 1 are provided with arc-shaped grooves 5, and the bottom of the inner side of the arc-shaped groove 5 is inclined downward towards the inside of the slag extraction and treatment box 1. The bottom of the inner side of the arc-shaped groove 5 is inclined downward from the middle to both sides. Both ends of the bottom of the side of the arc-shaped groove 5 near the inside of the slag extraction and treatment box 1 are provided with inlet ports 6.

[0040] During drilling, the external trenching machine first drives the trenching rollers 432 on the two trenching components 43 to contact the ground. Several trenching rollers 432 near the slag removal box 1 are located within the arc-shaped groove 5. The first motor 421 is controlled to operate, driving the first gear 422 to rotate, which in turn drives the second gear 423 to rotate. This causes the rotating sleeve 431, equipped with teeth 433 and meshing with them, to rotate along its outer side. With the cooperation of the two first motors 421, the two rotating sleeves 431 rotate synchronously and in opposite directions, both rotating towards the slag removal box 1. This causes several trenching rollers 432 installed on the outer side of one rotating sleeve 431 to rotate counterclockwise, and several trenching rollers 432 installed on the outer side of the other rotating sleeve 431 to rotate clockwise, thus performing trenching operations on the ground. With the assistance of the trenching machine, the trench gradually penetrates deeper into the ground, and the excavated soil is excavated according to the rotation of the two rotating sleeves. The rotation direction of the moving sleeve 431 gradually converges between the two troughing rollers 432 and falls into the receiving groove 434 set on the troughing roller 432. During the rotation, when the troughing roller 432 rotates to be located in the arc-shaped groove 5, due to the inclined bottom of the receiving groove 434, the soil falls into the arc-shaped groove 5 under the action of gravity and enters the slag extraction and processing box 1 through the inlet 6 at the bottom of the arc-shaped groove 5, so as to facilitate subsequent slag extraction processing. Through the cooperation of the above components, the soil generated during drilling and troughing is concentrated and collected, so as to facilitate a more comprehensive slag extraction operation.

By controlling the operation of two dual-shaft motors 724, the second drive wheel 723 and the first drive wheel 722 rotate, driving the two conveyor belts 725 synchronously towards the slag extraction port 2 at the top of the slag extraction and processing box 1. At the same time, the second bevel gear 742 rotates under the transmission of the two linkage pulleys 743 and the mating belt 744, thereby driving the first bevel gear 741 to rotate, which in turn causes the first auger 712 and the second auger 713 to rotate synchronously, conveying the soil and debris falling onto them upwards. After the soil and debris are conveyed to the bottom of the first auger 712 or the second auger 713 and pass through the through-hole on the discharge mounting plate 711, they naturally fall onto the discharge mounting plate 711. The portion of soil and debris located between the first auger 712 and the second auger 713 on the discharge mounting plate 711 falls back onto the first auger 712 or the second auger 713 via the ramps on both sides, until it falls on the top of the discharge mounting plate 711 between the first auger 712 and the second auger 713. At the same time, as the two conveyor belts 725 move synchronously toward the slag extraction port 2 at the top of the slag extraction box 1, several shovel plates 73 on the two conveyor belts 725 shovel up the soil and debris on the discharge mounting plate 711 and convey it upward between the two conveyor belts 725. During the conveying process, the shovel plates 73 on the two conveyor belts 725 apply a compressive force to the soil and debris, thereby achieving the effect of conveying the soil and debris to the slag extraction port 2 while crushing the soil and debris, thus avoiding the blockage problem during the slag extraction process.

[0045] In this embodiment, as Figure 16 As shown, each of the gathering components 75 includes a linkage plate 751, a trigger block 752, a reset spring 753, a toothed rod 754, a drive gear 755, a connecting rod 756, and an arc-shaped rod 757. The lower ends of the first auger 712 and the second auger 713 are hollow. The drive gear 755 is horizontally and rotatably disposed at the lower end of the first auger 712. The toothed rod 754 meshes with one side of the drive gear 755. One end of the toothed rod 754 is provided with a trigger block 752, and the other end of the trigger block 752 passes through the side end of the first auger 712 and slides with it. 2. One end of the first auger 712 is arc-shaped, and the inner side of the bottom of the slag removal box 1 is provided with a linkage plate 751. The linkage plate 751 is provided with a bevel on the side near the trigger block 752. The two ends of the reset spring 753 are respectively connected to the lower end of the trigger block 752 and the inner side wall of the first auger 712. One end of the connecting rod 756 is coaxially connected to the drive gear 755. The other end of the connecting rod 756 is rotatably connected to one end of the arc-shaped rod 757. The other end of the arc-shaped rod 757 passes through the side wall of the first auger 712 and is slidably connected to it. The arc-shaped rod 757 is located at the bottom of the first auger 712.

[0046] During the upward conveying of soil and slag by the first auger 712 or the second auger 713, the soil and slag located between or on both sides of the bottom of the first auger 712 and the second auger 713 can also be conveyed. In order to increase the conveying capacity of the soil and slag, the trigger block 752 on its outer side moves in a circular motion during its rotation. During the movement, it contacts the linkage plate 751. The linkage plate 751 squeezes the trigger block 752, causing it to slide inward to the first auger 712 or the second auger 713. This, in turn, drives the toothed rod 754 to slide, which in turn drives the drive gear 755 to rotate counterclockwise. The connecting rod 756 rotates counterclockwise, causing the arc rod 757 to slide in an arc-shaped motion trajectory to the outer side of the first auger 712 or the second auger 713. When the trigger block 752 disengages from the linkage plate 751, the reset spring 753 resets, causing the trigger block 752 to reset and slide to the outside of the first auger 712 or the second auger 713. This causes the arc rod 757 to slide along an arc-shaped trajectory to the inside of the first auger 712 or the second auger 713. Through the movement trajectory of the arc rod 757, while the first auger 712 or the second auger 713 is conveying soil and slag, the soil and slag at its end can be gathered. This gathers the soil and slag located on the outside to the vicinity of the first auger 712 or the second auger 713 and makes them relatively close, thereby improving the soil and slag conveying range of the first auger 712 or the second auger 713 and further increasing its soil and slag conveying capacity.

[0047] The method of use and advantages of this invention: The method of using this drilling equipment for ultra-deep foundation pit construction is as follows:

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 As shown:

[0049] S1: First, this equipment is installed on the output end of the trenching machine. The trenching machine controls this equipment to go deep underground to perform drilling operations. The top slag extraction port 2 of the slag extraction treatment box 1 is connected to a slag extraction pipe, and a slag extraction device is set up externally. The slag extraction device can pump the soil and slag in the hole to the outside of the hole through the slag extraction pipe. First, the external trenching machine drives the trenching rollers 432 on the two trenching components 43 to contact the ground. Some of the trenching rollers 432 near the slag extraction treatment box 1 are located in the arc-shaped groove 5. The first motor 421 is controlled to work, driving the first gear 422 to rotate, which in turn drives the second gear 423 to rotate. This causes the rotating sleeve 431, equipped with teeth 433 and meshing with them, to rotate along its outer side. With the cooperation of the two first motors 421, the two rotating sleeves 431 rotate synchronously and in opposite directions, both rotating towards the slag-collecting box 1. This causes several troughing rollers 432 installed on the outer side of one rotating sleeve 431 to rotate counterclockwise, and several troughing rollers 432 installed on the outer side of the other rotating sleeve 431 to rotate clockwise, thereby performing drilling and troughing operations on the ground. With the help of the machine, the soil gradually penetrates deeper into the ground, and the soil generated by the drilling gradually gathers between the two troughing rollers 432 according to the rotation direction of the two rotating sleeves 431. It falls into the receiving groove 434 set on the troughing roller 432. During the rotation, when the troughing roller 432 rotates to be located in the arc-shaped groove 5, the soil falls into the arc-shaped groove 5 under the action of gravity because the bottom of the receiving groove 434 is inclined. It enters the slag extraction and processing box 1 through the inlet 6 at the bottom of the arc-shaped groove 5 for subsequent slag extraction processing.

[0050] S2: The soil and debris formed by drilling enter the slag extraction and treatment box 1 through two feed ports 6, and fall onto the first auger 712 and the second auger 713. By controlling the operation of two dual-shaft motors 724, the second drive wheel 723 and the first drive wheel 722 rotate, driving the two conveyor belts 725 synchronously towards the slag extraction port 2 at the top of the slag extraction and treatment box 1. At the same time, the second bevel gear 742 rotates under the transmission of the two linkage pulleys 743 and the cooperating belt 744, thereby driving the first bevel gear 741 to rotate, which in turn causes the first auger 712 and the second auger 713 to rotate synchronously, conveying the soil and debris falling on them upwards. After the soil and debris are conveyed to the bottom of the first auger 712 or the second auger 713 and pass through the through-hole on the discharge mounting plate 711, they naturally fall onto the discharge mounting plate 711. The portion of soil and slag located between the first auger 712 and the second auger 713 on the 11th section, falling onto the ends of the discharge mounting plate 711, falls back onto the first auger 712 or the second auger 713 via the ramps on both sides, until it falls onto the top of the discharge mounting plate 711 between the first auger 712 and the second auger 713. At the same time, as the two conveyor belts 725 move synchronously toward the slag extraction port 2 at the top of the slag extraction box 1, several shovel plates 73 on the two conveyor belts 725 shovel up the soil and slag on the discharge mounting plate 711 and convey it upward between the two conveyor belts 725. During the conveying process, the shovel plates 73 on the two conveyor belts 725 apply a compressive force to the soil and slag, thereby achieving the effect of conveying the soil and slag to the slag extraction port 2 while simultaneously crushing the soil and slag, thus avoiding blockage problems during the slag extraction process.

[0051] S3: During the upward conveying of soil and slag by the first auger 712 or the second auger 713, the soil and slag located between or on both sides of the bottom of the first auger 712 and the second auger 713 can also be conveyed. In order to increase the conveying capacity of the soil and slag, during its rotation, the trigger block 752 on its outer side performs a synchronous circular motion. During the motion, it contacts the linkage plate 751. The linkage plate 751 squeezes the trigger block 752, causing it to slide inward to the first auger 712 or the second auger 713, thereby driving the toothed rod 754 to slide, which in turn drives the drive gear 755 to rotate counterclockwise. The connecting rod 756 rotates counterclockwise, causing the arc rod 757 to slide in an arc-shaped motion trajectory to the first auger 712 or the second auger 713. On the outside, when the trigger block 752 disengages from the linkage plate 751, the reset spring 753 resets and drives the trigger block 752 to reset, sliding to the outside of the first auger 712 or the second auger 713. This causes the arc rod 757 to slide along an arc-shaped trajectory to the inside of the first auger 712 or the second auger 713. Through the trajectory of the arc rod 757, while the first auger 712 or the second auger 713 is conveying soil and slag, the soil and slag at its end can be gathered. This gathers the soil and slag located on the outside to the vicinity of the first auger 712 or the second auger 713 and makes it relatively close, thereby improving the soil and slag conveying range of the first auger 712 or the second auger 713 and further increasing its soil and slag conveying capacity.

8. The method of using the drilling equipment for ultra-deep foundation pit construction according to claim 7, characterized in that, Includes the following steps: S1: First, this equipment is installed on the output end of the trenching machine. The trenching machine controls this equipment to go deep underground to perform drilling operations. The top slag extraction port (2) of the slag extraction treatment box (1) is connected to a slag extraction pipe, and a slag extraction device is set up externally. The slag extraction device can extract the soil and slag in the hole to the outside of the hole through the slag extraction pipe. First, the external trenching machine drives the trenching rollers (432) on the two trenching components (43) to contact the ground. Some of the trenching rollers (432) near the slag extraction treatment box (1) are located in the arc groove (5). The first motor (421) is controlled to work, driving the first gear (422) to rotate and then driving the second gear (423) to rotate. This drives the rotating sleeve (431) with teeth (433) and meshing with it to rotate along its outer side. With the cooperation of the two first motors (421), the two rotating sleeves (431) are driven to rotate synchronously and in opposite directions. The two rotating sleeves (432) rotate synchronously and in opposite directions. 1) They all rotate in the direction of the slag removal processing box (1), thereby driving several grooving rollers (432) installed on the outside of one of the rotating sleeves (431) to rotate counterclockwise, and driving several grooving rollers (432) installed on the outside of the other rotating sleeve (431) to rotate clockwise, thereby drilling and grooving the ground. With the cooperation of the grooving machine, they gradually penetrate the ground and dig deeper and deeper. The soil generated by drilling gradually gathers between the two grooving rollers (432) according to the rotation direction of the two rotating sleeves (431), and falls into the receiving groove (434) set on the grooving roller (432). During the rotation, when the grooving roller (432) rotates to be located in the arc groove (5), since the bottom of the receiving groove (434) is inclined, the soil falls into the arc groove (5) under the action of gravity and enters the slag removal processing box (1) through the inlet (6) at the bottom of the arc groove (5) for subsequent slag removal processing. S2: The soil and debris formed by drilling enter the slag removal and treatment box (1) through two feed ports (6) and fall onto the first auger (712) and the second auger (713). By controlling the operation of two dual-shaft motors (724), the second drive wheel (723) and the first drive wheel (722) rotate, driving the two conveyor belts (725) to move synchronously towards the slag removal port (2) at the top of the slag removal and treatment box (1). At the same time, under the transmission of the two linkage pulleys (743) and the matching belt (744), the second bevel gear (742) rotates, thereby driving the first bevel gear (741) to rotate, which in turn causes the first auger (712) and the second auger (713) to rotate synchronously, conveying the soil and debris falling on them upwards. After the soil and debris are conveyed to the bottom of the first auger (712) or the second auger (713) and pass through the through-hole on the discharge mounting plate (711), they are discharged from the bottom. The portion of soil falling onto the discharge mounting plate (711) between the first auger (712) and the second auger (713), and the portion of soil falling onto both ends of the discharge mounting plate (711) falling back onto the first auger (712) or the second auger (713) via the slopes on both sides, until it falls onto the top of the discharge mounting plate (711) between the first auger (712) and the second auger (713). At the same time, as the two conveyor belts (725) are driven synchronously toward the top slag extraction port (2) of the slag extraction box (1), several shovel plates (73) on the two conveyor belts (725) shovel up the soil on the discharge mounting plate (711) and transport it upward between the two conveyor belts (725). During the transport process, the shovel plates (73) on the two conveyor belts (725) apply a squeezing force to the soil, thereby realizing the simultaneous transport of the soil to the slag extraction port (2) and the crushing of the soil. S3: During the upward conveying of soil by the first auger (712) or the second auger (713), in order to increase the conveying capacity of the soil, the trigger block (752) on its outer side moves in a circular motion during its rotation. During the motion, it contacts the linkage plate (751). The linkage plate (751) squeezes the trigger block (752), causing it to slide towards the inside of the first auger (712) or the second auger (713), thereby driving the toothed rod (754) to slide, which in turn drives the drive gear (755) to rotate counterclockwise. The connecting rod (756) rotates counterclockwise, causing the arc rod (757) to slide along an arc-shaped trajectory to the outside of the first auger (712) or the second auger (713). When the trigger block (752) disengages from the linkage plate (751), 1) After that, the reset spring (753) resets and drives the trigger block (752) to reset, sliding to the outside of the first auger (712) or the second auger (713), thereby driving the arc rod (757) to slide to the inside of the first auger (712) or the second auger (713) in an arc motion trajectory. Through the motion trajectory of the arc rod (757), while the first auger (712) or the second auger (713) is conveying soil and slag, the soil and slag at its end can be gathered, so that the soil and slag located on the outside can be gathered to the vicinity of the first auger (712) or the second auger (713) and relatively close, which is conducive to improving the soil and slag conveying range of the first auger (712) or the second auger (713) and further increasing its soil and slag conveying capacity.
