DETAILED DESCRIPTION

[0018] 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.

[0019] Please see attached Figure 1 and attached Figure 7 The embodiment of the present invention provides an environmentally friendly and dustproof ground hole-opening device for construction, comprising a mobile chassis 1, an operating platform 2, an operating arm 3 and an operating cabin 4 are arranged on the top of the mobile chassis 1, a water tank 6 is arranged on the operating platform 2, and a hole-opening mechanism 5 is arranged on the operating arm 3. The hole-opening mechanism 5 comprises a mounting platform 501, the mounting platform 501 is arranged on the operating arm 3, a motor 502 is arranged inside the mounting platform 501, and a drill bit 503 is fixedly connected to the output end of the motor 502; The mobile chassis 1 serves as the mobile foundation of the entire device and undertakes the important task of supporting and moving the entire drilling device, ensuring that the device can be flexibly transferred under the ground conditions of different construction sites and accurately positioned to the specific location where drilling operations are required. The operating cabin 4 provides a relatively closed and comfortable working space for the operator, so that the operator is protected from interference and influence of harsh external environmental factors (such as dust, noise, weather changes, etc.) during the complex drilling operations, thereby ensuring that the operator can concentrate on operating the entire device accurately and efficiently. The operating arm 3 meets the drilling operation requirements at different positions and angles, and the water tank 6 serves as a water source storage container for the entire device. The mounting platform 501 provides a stable and reliable installation base for installing components such as the motor 502, ensuring the smooth progress of the hole-opening operation. The motor 502 is the core power component of the hole-opening mechanism, and the drill bit 503 is the key working component that directly contacts the ground and performs cutting operations. In addition, the drill bit 503 can ensure efficient and accurate hole-opening operations under various complex ground conditions.

[0020] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 7 , a dust reduction mechanism 7 is arranged on the hole opening mechanism 5, and the dust reduction mechanism 7 includes a fixed block 702, which is arranged on the mounting platform 501 in the hole opening mechanism 5, and a nozzle 1 703 is arranged inside the fixed block 702, and a mounting frame 704 is arranged on the front side of the operating table 2, and a spray pipe 705 is arranged on the mounting frame 704, and a plurality of horizontally arranged nozzles 2 706 are arranged on the spray pipe 705 at equal intervals, and a water pump 701 is arranged on the top of the operating table 2, and the input end of the water pump 701 is connected to the water tank 6 through a water pipe, and the output end of the water pump 701 is connected to the nozzle 1 703 and the nozzle 2 706 through a water pipe; Nozzle 1 703 is a key component in the dust reduction system that directly performs dust reduction treatment on the drill bit 503. It forms a moist protective layer around the drill bit 503 by spraying water, effectively preventing dust from flying outward, thereby achieving efficient control of dust in the area near the drill bit 503. The spray pipe 705 installed on the mounting frame 704 is the main component of the entire dust reduction system responsible for large-area spray dust reduction. The water mist sprayed by nozzle 2 706 can evenly cover the surrounding space of the opening operation area. Multiple nozzles 706 work together to form a large-scale spray dust reduction network. When the dust generated during the hole opening process diffuses to the area, it will be fully mixed with the water mist sprayed by nozzle 2 706 and gradually settle to the ground under the action of gravity, thereby effectively reducing the dust concentration in the air, further expanding the scope of action of the dust reduction mechanism, and improving the environmental dust reduction effect of the entire device. The water pump 701 serves as the power source of the entire dust reduction mechanism, and is responsible for extracting water from the water tank 6 and pressurizing it to nozzle 1 703 and nozzle 2 706.

[0021] Please see attached Figure 1 -Attached Figure 5 A wastewater recovery mechanism 8 is provided on the operating table 2, and the wastewater recovery mechanism 8 includes a sedimentation tank 801, and the sedimentation tank 801 is provided on the operating table 2. An extraction pump 804 is provided in the sedimentation tank 801, and an input end of the extraction pump 804 is connected to an extraction head 803 through an extraction pipe 802, and an output end of the extraction pump 804 is connected to the interior of the sedimentation tank 801 through a water pipe, and a filter assembly is provided on the extraction pipe 802; The sedimentation tank 801 is used as a storage place for dust-containing wastewater formed by dust precipitation and groundwater mixture that may seep out due to geological conditions. The extraction pump 804 is a key power device in the entire wastewater recovery system responsible for extracting wastewater from the opening and transporting it to the sedimentation tank 801. The extraction head 803 and the extraction pipe 802 play a connecting role. The filter assembly includes two filter tubes 805, which are connected to each other by hexagonal bolts. The filter tube 805 is set on the extraction tube 802. A slot 806 is opened in the filter tube 805. The slot 806 is snap-connected with a snap ring 807. A sand and gravel filter net 808 is set on the snap ring 807. The slot 806 provides a stable and reliable snap-connection position for the snap ring 807. The snap ring 807 is used for the installation of the sand and gravel filter net 808. The sand and gravel filter net 808 can filter sand and gravel and other materials left in the wastewater during the extraction process.

[0022] Please see attached Figure 1 -Attached Figure 6 The wastewater recovery mechanism 8 is provided with a reflux component 9 and a sand discharge mechanism 10. The reflux component 9 includes a reflux pipe 901. The reflux pipe 901 is arranged on the top of the sedimentation tank 801, and the sedimentation tank 801 is connected to the water tank 6 through the reflux pipe 901. The reflux pipe 901 is provided with a reflux box 902 and a reflux valve 903. The reflux box 902 is provided with a quartz sand filter layer 904 and an activated carbon filter layer 905 from top to bottom. The reflux pipe 901 is used as a key channel connecting the sedimentation tank 801 and the water tank 6. The reflux box 902 is used as a key purification link in the reflux process, which plays a role in accommodating and installing the quartz sand filter layer 904 and the activated carbon filter layer 905. The function of the activated carbon filter layer 905 is that when the wastewater flows through the quartz sand filter layer 904, the tiny particle impurities, colloidal substances and some microorganisms remaining in the water will be adsorbed, intercepted and filtered by the quartz sand particles. The activated carbon filter layer 905 is located below the quartz sand filter layer 904. The activated carbon has a huge specific surface area and rich microporous structure, which can adsorb organic pollutants, odor substances, heavy metal ions and residual pesticides, fertilizers and other harmful substances in the wastewater. The reflux valve 903 is installed on the reflux pipe 901 at a position associated with the reflux box 902. Its function is to control the flow rate and direction of the wastewater during the reflux process.

[0023] Please see attached Figure 3-Attached Figure 6 The sand discharge mechanism 10 includes two groups of sand discharge mounting blocks 1001, which are respectively arranged on the inner bottom wall of the sedimentation box 801. Two groups of transmission wheels 1002 and motor 2 1009 are arranged inside the sand discharge mounting blocks 1001. The output end of motor 2 1009 is connected to one of the transmission wheels 1002. The transmission wheels 1002 in the same sand discharge mounting block 1001 are connected by a transmission belt 1003. The transmission belt 1003 is connected to a connecting rod 1004 through a mounting assembly. A push plate 1005 is arranged on the connecting rod 1004. A slider 2 1011 is arranged on the inner left wall of the sedimentation box 801. The slider 2 1011 is slidably connected to a collection frame 1010. A traction assembly is arranged on the collection frame 1010. The sand discharge mounting block 1001 provides a solid and reliable installation for a series of sand discharge transmission components. The motor 1009 is one of the power sources of the sand discharge mechanism 10. The transmission wheel 1002 can stably transmit the power through the transmission belt 1003 to achieve accurate power transmission and conversion, and provide reliable power support for the subsequent sand discharge action. On the connecting rod 1004, a push plate 1005 is firmly installed. The material of the push plate 1005 is usually selected from rubber or plastic materials that are wear-resistant, corrosion-resistant and have a certain elasticity. Its shape and size are optimized according to the bottom shape of the sedimentation box 801 and the accumulation characteristics of the sediment. The front edge of the push plate 1005 is usually designed to be an arc or an inclined surface, so that it can better cut into the sediment layer during the movement, and effectively push the sediment at the bottom of the sedimentation box 801 to achieve the purpose of sand discharge. The collection frame 1010 is used as a container for collecting sediment in the sedimentation box 801; The installation assembly includes two sliders 1006, which are respectively arranged on adjacent sides of the transmission belt 1003. The sliders 1006 are slidably connected to the sliding frame 1007, and the sliding frame 1007 is provided with a connecting block 1008. The connecting rod 1004 is arranged between the connecting blocks 1008. The sliding frame 1007 can provide a stable sliding track and a limit function for the sliders 1006. The sliders 1006 can drive the sliding frame to move, and the connecting rod 1004 connected by the connecting block 1008 can maintain horizontal stability even in the resetting process. The traction assembly includes a traction mounting block 1012, which is arranged on the top of the sedimentation box 801. A reeling shaft 1013 and a reeling motor 1014 are arranged on the traction mounting block 1012. The output end of the reeling motor 1014 is fixedly connected to the reeling shaft 1013. A hanging ring 1015 is arranged on the collection frame 1010. The hanging ring 1015 is connected to the reeling shaft 1013 through a traction rope 1016. The reeling motor 1014 serves as a power source for the traction assembly. When the reeling motor 1014 drives the reeling shaft 1013 to rotate, the hanging ring 1015 provides a point of action for the connection of the traction rope 1016. Through the connection between the traction rope 1016 and the hanging ring 1015, the collection frame 1010 can be smoothly pulled out of the sedimentation box 801 along the slider 1011, thereby realizing the convenient movement and cleaning operation of the collection frame 1010, and improving the automation degree and working efficiency of the sand discharge mechanism 10.

[0024] Please see attached Figure 1 -Attached Figure 2 A dust concentration sensor 11 is provided on the operating arm 3. The dust concentration sensor 11 transmits the collected data to the central control system. The dust concentration sensor 11 can accurately sense the concentration changes of dust particles in the surrounding air, and provide key real-time data basis for subsequent environmental protection dust reduction control.

[0025] Please see attached Figure 8 , the central control system includes: Collection module: used to transmit the data collected by the dust concentration sensor 11 to the central control system; Analysis module: It analyzes the data collected in the central control system through the data processing unit; Driving module: drives the water pump 701 through the analyzed information.

[0026] Working principle: The crawler of the mobile chassis 1 is used to move the equipment to the position where a hole needs to be drilled. Then the operator enters the operation cabin 4 and operates the operating arm 3 to align the drill bit 503 with the drilling position. Then the motor 502 is started, and the motor 502 makes the drill bit 503 rotate at a high speed. The rotating drill bit 503 drills a hole in the ground. During the drilling process, dust is raised at the construction site and then detected by the dust concentration sensor 11. When the specified threshold is reached, the central control system starts the water pump 701 and adjusts the water concentration according to the dust concentration at the site. The output power of the water pump 701 is adjusted, and then the water pump 701 pumps the water in the water tank 6 to the spray pipe 705 on the mounting frame 704 and the nozzle 1 703 on the fixed block 702. The water flow sprayed by the nozzle 1 703 is directly sprayed to the drill bit 503. After the drill bit 503 is soaked in water, it can not only cool the surface, but also part of the dust generated by the hole is fused with water and remains on the drill bit 503. The water flow flowing into the spray pipe 705 is sprayed from the nozzle 2 706 in atomization. The water mist sprayed by the nozzle 2 706 combines with the raised dust and sinks; After the drilling is completed, mud will remain in the drilled hole. The water source of the mud is partly derived from the water sprayed from the nozzle 703 to the drill bit 503, and the other part is groundwater. At this time, the extraction pipe 802 is taken out, the extraction head 803 is aimed at the mud in the hole, and the extraction pump 804 is started to pump this part of the water source into the sedimentation tank 801. The gravel is intercepted by the sand and gravel filter 808 in the filter tube 805. The filtered mud enters the sedimentation tank 801 for precipitation. The precipitated mud begins to stratify, and then the return valve 903 is started to pump the upper layer of water to the return tank 902 through the return pipe 901, and the water is filtered through the quartz sand filter layer 904 and the activated carbon filter layer 905 in the return tank 902. The filtered water returns to the water tank 6 through the return pipe 901 for the next drilling or construction site water use; After the mud is recovered, the filter tube 805 is opened by the hexagonal bolts, the retaining ring 807 in the retaining groove 806 is removed, and the sand and gravel filter screen 808 on the retaining ring 807 is cleaned and replaced. There is still mud and sand after the mud is precipitated in the sedimentation box 801. Then the motor 1009 is started, and the motor 1009 causes the transmission wheel 1002 to rotate. The rotation of the transmission wheel 1002 causes the transmission belt 1003 to move, and the slider 1006 on the transmission belt 1003 moves accordingly. The moving slider 1006 drives the sliding frame 1007 and the connecting block under the restriction of the sliding frame 1007. 1008 moves, and the connecting rod 1004 and the push plate 1005 move under the installation of the connecting block 1008, and the push plate 1005 pushes the mud and sand into the collecting frame 1010, and then the winding motor 1014 on the traction mounting block 1012 is started, and the winding motor 1014 causes the winding shaft 1013 to rotate, and the rotating winding shaft 1013 winds up the traction rope 1016, and the wound traction rope 1016 is connected to the hanging ring 1015, so that the collecting frame 1010 slides out along the slider 1011 until it moves out of the sedimentation box 801, and the mud and sand in the collecting frame 1010 can be cleaned at this time.
