[0001] The invention relates to the technical field of tomb excavation equipment, in particular to a tomb excavation device and a use method thereof. Background Art

[0002] In modern society, as people pay more and more attention to the ecological environment and health, traditional tomb excavation methods have gradually revealed their shortcomings in safety and environmental protection. Existing tomb excavation devices usually rely on mechanical means to excavate the soil. However, these devices will generate a lot of dust during operation, posing a threat to the surrounding environment and the health of operators. According to research, long-term exposure to high-concentration dust environments may lead to respiratory diseases and other health problems.

Step 4: Start the first hydraulic cylinder to drive the rotating block to swing. At this time, the mounting frame swings under the rotation of the rotating disk, so that the angle of the drill rod changes, so as to accurately control the excavation depth and direction and reduce errors; Step 5: During the tomb excavation process, the second hydraulic cylinder is activated to move the support base downward. When the support base contacts the ground, the frame moves upward, thus ensuring stability during the tomb excavation process.

[0016] The present invention provides a tomb excavation device and a method of using the same, which has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please refer to the attached Figure 1 - Attachment Figure 8The embodiment of the present invention provides a tomb excavation device, including a frame 1, a support plate 8 is fixedly connected to one side of the top of the frame 1, a filter box 501 is fixedly connected to the top of the support plate 8, an exhaust fan 502 is installed on the outside of the filter box 501, a connecting pipe 504 is connected to the outside of the filter box 501, a dust hopper 503 is fixedly connected to one end of the connecting pipe 504, two filter screens 505 are detachably connected to the inside of the filter box 501, a driving shaft 705 is rotatably connected to one side of the inside of the filter screen 505, a driving gear 701 is fixedly connected to the outside of the driving shaft 705, two limit plates 704 are fixedly connected to the outside of the filter screen 505, a driving rack 703 is slidably connected to the outside of the limit plate 704, a scraper 702 is fixedly connected to the outside of the driving rack 703, a support frame 2 is fixedly connected to the other side of the top of the frame 1, an excavation component is installed on the outside of the support frame 2, and the excavation component is used to excavate the tomb.

[0022] Specifically, the frame 1 is the basic frame of the entire excavation device, which has a stable support structure and can withstand the loads generated by each component during operation. The material of the frame 1 is a corrosion-resistant and high-strength alloy material to ensure the service life of the device in various environments. The support plate 8 provides a stable support surface for the upper equipment. The design of the support plate 8 focuses on its rigidity and bending resistance to ensure that it can provide good support during the excavation process. The exhaust fan 502 can effectively suck dust in the air into the filter box 501 through its strong exhaust capacity to maintain the air quality in the working area. The connecting pipe 504 is responsible for transporting dust from the dust hopper 503 to the filter box 501. Two filter screens 505 are detachably connected inside the filter box 501, which are designed to filter fine particles to ensure that the discharged air is clean. The material of the filter screen 505 is a high-efficiency filter material with good air permeability and filtering performance, which is convenient for regular cleaning or replacement. The drive rack 703 and the drive gear 701 are meshed with each other to form an efficient transmission system. The scraper 702 is fixedly connected to the outer side of the driving rack 703 and is responsible for cleaning the dust on the surface of the filter 505 to prevent the filter 505 from being blocked and maintain a good filtering effect.

[0023] The excavation assembly includes a dual-axis servo motor 301, which is fixedly connected to the top of the support frame 2. One of the output ends of the dual-axis servo motor 301 is fixedly connected to a driving screw 302. The outer side of the driving screw 302 is threadedly connected to a threaded plate 304. A mounting frame 305 is provided on the outer side of the threaded plate 304. A driving motor 306 is installed on the top of the mounting frame 305. The output end of the driving motor 306 is fixedly connected to a drill rod 303. A guide rod 9 is slidably connected to the inner through hole of the threaded plate 304. The upper and lower ends of the guide rod 9 are fixedly connected to the inner side of the support frame 2.

[0024] Specifically, the drive screw 302 is fixedly connected to an output end of the dual-axis servo motor 301, and is responsible for converting the rotational motion of the motor into linear motion. The outer thread design of the drive screw 302 matches the inner thread of the threaded plate 304 to ensure effective connection and matching between the two, so that the threaded plate 304 can achieve smooth up and down movement under the drive of the motor. The mounting frame 305 is fixed to the outer side of the threaded plate 304, providing a stable installation foundation for the drive motor 306. The drive motor 306 is installed at the top of the mounting frame 305 and is responsible for driving the rotation of the drill rod 303. The motor has high power and torque output, which can ensure that the drill rod 303 rotates smoothly during the excavation process and ensure the depth and quality of the drill hole. The drill rod 303 is fixedly connected through the output end of the drive motor 306 and is responsible for transmitting the rotational power to the soil. The design of the drill rod 303 adopts a suitable diameter and length to adapt to different types of soil. At the same time, its tip is specially designed to effectively penetrate the soil and improve the excavation efficiency. The guide rod 9 plays a guiding and stabilizing role, ensuring that the upward and downward movement path of the threaded plate 304 is straight and stable during the excavation process, thereby preventing inaccurate excavation or equipment damage caused by deviation.

[0025] Please refer to the attached Figure 4 A first hydraulic cylinder 401 and a rotating disk 402 are installed on the outer side of the threaded plate 304. The output end of the first hydraulic cylinder 401 is rotatably connected to a rotating block 403. The rotating block 403 is rotatably connected to one side of the bottom end of the mounting frame 305. The rotating disk 402 is rotatably connected to the outer side of the threaded plate 304. The outer side of the rotating disk 402 is fixedly connected to the outer side of the mounting frame 305.

[0026] Specifically, by starting the first hydraulic cylinder 401 to drive the rotating block 403 to swing, the mounting frame 305 swings under the rotation of the rotating disk 402, so that the angle of the drill rod 303 changes, thereby accurately controlling the excavation depth and direction and reducing errors.

[0027] The scraper 702 is made of a flexible material, and the outer surface of the scraper 702 is in contact with the outer surface of the filter screen 505 . The outer side of the driving gear 701 is meshed and connected with the outer sides of the two driving racks 703 .

[0028] Specifically, the scraper 702 is made of a flexible material and has good flexibility and adaptability. The flexible material enables the scraper 702 to fit closely to the outer surface of the filter 505 during the cleaning process, effectively removing dust and debris attached to the filter 505. The scraper 702 can move evenly along the surface of the filter 505. Through the meshing of the rack and the gear, high-precision linear motion can be achieved, so that the scraper 702 can effectively cover the entire surface of the filter 505, ensuring the consistency and thoroughness of the cleaning effect.

[0029] Please refer to the attached Figure 1, Attachment Figure 5 and attached Figure 6 , one end of the driving shaft 705 is fixedly connected to the second transmission rod 602, the outer side of the second transmission rod 602 is fixedly connected to the first bevel gear 603, the outer side of the support frame 2 is rotatably connected to the first transmission rod 601, the bottom end of the first transmission rod 601 is fixedly connected to the second bevel gear 604, the top end of the first transmission rod 601 is fixedly connected to the first synchronous wheel 11, and the first synchronous wheel 11 is connected to the second synchronous wheel 12 through a belt. The second synchronous wheel 12 is fixedly connected to the other output end of the dual-axis servo motor 301, and the outer side of the second bevel gear 604 is meshed with the outer side of the first bevel gear 603.

[0030] Specifically, when the dual-axis servo motor 301 is started, it will also drive the second synchronous wheel 12 to rotate, and under the action of the belt, it will drive the first synchronous wheel 11 to rotate synchronously, thereby driving the first transmission rod 601 and the second bevel gear 604 to rotate coaxially. Since the second bevel gear 604 and the first bevel gear 603 are meshed with each other, the rotation of the second bevel gear 604 will drive the first bevel gear 603 to rotate coaxially, thereby further driving the second transmission rod 602 to rotate synchronously.

[0031] Please refer to the attached Figure 1 and attached Figure 2 The bottom end of the driving screw rod 302 is movably connected to the inner wall of the support frame 2 through a bearing, and the outer surface of the threaded plate 304 is slidably connected to the outer side of the support frame 2.

[0032] Specifically, the support frame 2 ensures the stability of the driving screw 302 during rotation.

[0033] Please refer to the attached Figure 1 - Attachment Figure 3 A plurality of connecting frames 1002 are fixedly connected to the outer side of the frame body 1, a second hydraulic cylinder 1001 is fixedly connected to the outer side of the connecting frame 1002, and a supporting base 1003 is fixedly connected to the output end of the second hydraulic cylinder 1001.

[0034] Specifically, the frame 1 is the main structure of the entire excavation device, and its stability and strength directly affect the efficiency and safety of the excavation work. The frame 1 is made of high-strength materials to ensure sufficient bearing capacity and durability during long-term use. The support base 1003 is the part that directly contacts the ground, and its design takes into account the bearing capacity and stability of the ground. The bottom surface of the support base 1003 has a large contact area, which helps to disperse gravity, reduce local soil pressure, and avoid the risk of ground subsidence or collapse.

[0035] During the tomb excavation process, the second hydraulic cylinder 1001 is first started, so that its output end pushes the support base 1003 downward. When the support base 1003 contacts the ground, the support base 1003 transmits force to the ground, thereby achieving a supporting effect. During this process, the frame 1 moves upward due to the downward movement of the support base 1003. This design not only improves the stability of the entire device, but also effectively reduces the operational vibration and deviation caused by soil unevenness.

[0036] By real-time monitoring of the working status of the hydraulic system, the output of the hydraulic cylinder can be adjusted in time to ensure the stability and adaptability of the support base 1003 under different ground conditions. At the same time, this design also effectively reduces the potential safety hazards that may occur during the operation and provides a safer working environment for operators.

[0037] A method for using a tomb excavation device comprises the following steps: Step 1: Start the driving motor 306 to rotate the drill rod 303. Then start the dual-axis servo motor 301 to rotate the driving screw 302, so that the threaded plate 304 moves up and down along the outer surface of the driving screw 302. The driving screw 302 in a rotating state is screwed into the ground to realize the excavation of the tomb. Step 2: Start the exhaust fan 502 to make the inside of the filter box 501 in a negative pressure state, and let the dust generated during the tomb excavation enter the connecting pipe 504 through the dust removal hopper 503, and then enter the inside of the filter box 501 through the connecting pipe 504, and finally be purified and absorbed by the filter screen 505. At this time, when the dual-axis servo motor 301 is started, it will also drive the second synchronous wheel 12 to rotate, and under the action of the belt, drive the first synchronous wheel 11 to rotate synchronously, so as to drive the first transmission rod 601 and the second bevel gear 604 to rotate coaxially. Since the second bevel gear 604 and the first bevel gear 603 are meshed with each other, the rotation of the second bevel gear 604 will drive the first bevel gear 603 to rotate coaxially, so as to further drive the second transmission rod 602 to rotate synchronously; Step 3: When the second transmission rod 602 rotates, it will drive the two driving gears 701 to rotate synchronously. Since the driving rack 703 and the driving gear 701 are meshed with each other, the rotation of the driving gear 701 will drive the two driving racks 703 to move closer to or away from each other. In this way, it is only necessary to control the frequency of the forward and reverse rotation of the top output end of the dual-axis servo motor 301 to realize the reciprocating movement of the two scrapers 702, so as to process the dust on the outer surface of the filter 505 and prevent the filter 505 from being blocked. Step 4: Start the first hydraulic cylinder 401 to drive the rotating block 403 to swing. At this time, the mounting frame 305 swings under the rotation of the rotating disk 402, so that the angle of the drill rod 303 changes, so as to accurately control the excavation depth and direction and reduce errors; Step 5: During the tomb excavation process, the second hydraulic cylinder 1001 is activated to move the support base 1003 downward. When the support base 1003 contacts the ground, the frame 1 moves upward, thus ensuring stability during the tomb excavation process.

Step 4: Start the first hydraulic cylinder (401) to drive the rotating block (403) to swing. At this time, the mounting frame (305) swings under the rotation of the rotating disk (402), so that the angle of the drill rod (303) changes, thereby accurately controlling the excavation depth and direction and reducing errors; Step 5: During the tomb excavation process, the second hydraulic cylinder (1001) is activated to move the support base (1003) downward. When the support base (1003) contacts the ground, the frame (1) moves upward, thereby ensuring stability during the tomb excavation process.
