Description

Technical Field

[0001] This invention relates to the field of municipal construction, specifically to a drilling machine and construction method for municipal engineering construction. Background Technology

[0002] Handheld post hole diggers are suitable for horticulture, urban greening, and planting trees on slopes. They can also be used in construction sites, geological and mining industries, power and transportation sectors for tasks such as laying piles, columns, exploration, and drilling. The main structural features of handheld post hole diggers include single-person or two-person operation models. The main structure consists of a frame, operating handles, gasoline engine, fuel tank, transmission clutch, and drill bit.

[0003] The existing handheld drilling rigs cannot monitor the verticality of the drilling process, resulting in a certain tilt deviation in the drilled hole, which affects subsequent tree planting and pile embedding operations. At the same time, the auger drill bits on the existing handheld drilling rigs are difficult to clean, resulting in a large amount of soil adhering to the surface of the drill bit, causing corrosion of the auger drill bit and affecting its service life. Summary of the Invention

[0004] To address the problems in the existing technology, the present invention provides a soil drilling machine for municipal engineering construction.

[0006] The monitoring mechanism includes mounting rods fixedly connected to two opposite side walls of the operating panel. The side walls of the two mounting rods are provided with sleeve rods, and the side walls of the two sleeve rods are provided with two mutually symmetrical reinforcing plates. T-shaped rods are slidably connected to the four reinforcing plates. U-shaped plates are provided on the side of the four T-shaped rods near the auger bit. A level is provided on the operating panel.

[0007] First springs are fitted on the side walls of the four T-shaped rods, and the two ends of the four first springs are respectively connected to the reinforcing plate and the U-shaped plate.

[0008] The U-shaped plate is provided with a cleaning mechanism for cleaning the spiral blades. The cleaning mechanism includes a first fixing plate disposed on the side of the U-shaped plate near the spiral blades. The U-shaped plate is provided with a driving mechanism for driving the first fixing plate. The first fixing plate is provided with a cleaning plate, the width of which is smaller than the pitch of the spiral blades.

[0009] The cleaning plate is provided with an auxiliary mechanism to ensure that the upper and lower side walls of the spiral blades are cleaned simultaneously. The auxiliary mechanism includes an auxiliary groove opened on the cleaning plate, a rubber airbag on the auxiliary groove, and an inflation mechanism for inflating the rubber airbag on the cleaning plate.

[0010] The inflation mechanism includes an inflation box fixedly connected to the cleaning plate. The inflation box is provided with an air inlet pipe that communicates with a rubber airbag. A sliding plate is slidably connected to the side wall of the cleaning plate. A push plate is provided on the side of the sliding plate near the inflation box. A piston plate is provided at one end of the push plate inside the inflation box. A push mechanism for pushing the sliding plate is provided on the cleaning plate.

[0011] The pushing mechanism includes a second fixed plate fixedly connected to the side wall of the cleaning plate, a first motor mounted on the second fixed plate, a third fixed plate mounted on the cleaning plate, a rotating rod mounted on the third fixed plate, the rotating rod being connected to the output end of the first motor, a fixed ring mounted on the side wall of the rotating rod, a plurality of pushing tubes rotatably connected to the fixed ring, a pushing rod slidably connected to each pushing tube, a pushing ball mounted at one end of each pushing rod, each pushing ball sliding on the side wall of the sliding plate, and a second spring mounted on the bottom wall of each pushing tube, the other end of the second spring being connected to the pushing rod.

[0012] The rotating rod has a fan blade at the end near the auger bit.

[0013] The sliding plate is provided with a reset mechanism to facilitate the reset of the air box. The reset mechanism includes a reset rod fixedly connected to the sliding plate, a reset tube sleeved on the side wall of the reset rod, a fourth fixing plate on the side wall of the air box, one end of the reset tube connected to the fourth fixing plate, a third spring on the bottom wall of the reset tube, and the other end of the third spring connected to the reset rod.

[0014] The driving mechanism includes two driving tubes fixedly connected to the side wall of the first fixed plate. One of the two driving tubes is slidably connected to a guide rod, one end of which is connected to a U-shaped plate. The other of the two driving tubes is threadedly connected to a threaded rod. A second motor is provided on the U-shaped plate, and one end of the threaded rod is connected to the output end of the second motor.

[0015] A construction method for a soil drilling rig used in municipal engineering construction includes the following steps:

[0016] S1: Hold the handles on the control panel with both hands and move the auger bit to the location where you need to drill. After reaching the drilling location, place the U-shaped plate against the ground and make minor adjustments to the U-shaped plate so that the bubble on the level on the control panel is in the center position.

[0017] S2: During the drilling process, pay attention to whether the bubble on the level is in the center position, and adjust it in time according to the situation of the bubble on the level to ensure that the auger bit is always perpendicular to the ground when drilling.

[0018] S3: After drilling to the required depth, the speed reducer stops rotating, thus stopping the auger bit from rotating. Under the drive of the drive mechanism, the cleaning plate enters the auger blades.

[0019] S4: The inflation mechanism injects gas from the inflation box into the rubber airbag, causing the rubber airbag to expand. The expanded rubber airbag will then press against the upper and lower side walls of the spiral blade.

[0020] S5: When the rubber airbag abuts against the upper and lower side walls of the spiral blade, start the reducer again to drive the spiral drill bit to rotate. By pulling the handle upward, the spiral drill bit will gradually move out of the hole. During the process of the spiral drill bit moving out of the hole, the rubber airbag will wipe the mud attached to the spiral blade clean.

[0021] The beneficial effects of this invention are:

[0022] (1) The drilling machine and construction method for municipal engineering construction described in this invention, through the setting of a monitoring mechanism, under the horizontal monitoring of the level, the auger bit is adjusted in time during the drilling process, so that the auger bit is always perpendicular to the ground for drilling, thereby ensuring the verticality of the drilled hole, which not only improves the aesthetics of subsequent tree planting, but also increases the safety of pile burying operation.

[0023] (2) The drilling machine and construction method for municipal engineering construction described in this invention, through the setting of the cleaning mechanism, under the driving action of the driving mechanism and the auxiliary action of the auxiliary mechanism, the rubber air bag is inflated by the inflation mechanism and then abuts against the upper and lower side walls of the spiral blade, wiping the soil attached to the spiral blade clean, ensuring the cleanliness of the spiral blade, avoiding the spiral blade from rusting due to the attached soil, and maintaining the normal service life of the spiral drill bit.

[0034] like Figure 1-6 As shown, a soil drilling machine for municipal engineering construction according to the present invention includes an operation plate 101 and a spiral drill bit. The spiral drill bit is composed of a drill rod 102 and a spiral blade 103. A reducer 104 is provided on one side of the operation plate 101, and the spiral drill bit is installed on the other side of the operation plate 101. The spiral drill bit is connected to the output end of the reducer 104. Two handles 105 are provided on the operation plate 101. The machine also includes a monitoring mechanism provided on the operation plate 101 for monitoring the verticality during the drilling process.

[0035] The monitoring mechanism includes mounting rods 201 fixedly connected to two opposite side walls of the operating panel 101. The side walls of the two mounting rods 201 are provided with sleeve rods 202. The side walls of the two sleeve rods 202 are provided with two mutually symmetrical reinforcing plates 203. T-shaped rods 204 are slidably connected to the four reinforcing plates 203. U-shaped plates 205 are provided on the side of the four T-shaped rods 204 near the auger bit. A level 206 is provided on the operating panel 101.

[0036] It should be noted that, through the monitoring mechanism, the auger bit is adjusted in a timely manner during the drilling process under the horizontal monitoring of the level 206, ensuring that the auger bit is always perpendicular to the ground. This guarantees the verticality of the drilled hole, which not only improves the aesthetics of subsequent tree planting but also increases the safety of the stake installation operation.

[0037] Specifically, four T-shaped rods 204 are fitted with first springs 3 on their side walls, and the two ends of the four first springs 3 are respectively connected to the reinforcing plate 203 and the U-shaped plate 205;

[0038] It should be noted that the first spring 3 serves two purposes: firstly, it ensures that the U-shaped plate 205 is always in contact with the ground, facilitating real-time detection of the verticality of the auger bit; secondly, it facilitates the resetting of the U-shaped plate 205 after drilling is completed.

[0039] Specifically, the U-shaped plate 205 is provided with a cleaning mechanism for cleaning the spiral blade 103. The cleaning mechanism includes a first fixing plate 401 disposed on the side of the U-shaped plate 205 near the spiral blade 103. The U-shaped plate 205 is provided with a driving mechanism for driving the first fixing plate 401. The first fixing plate 401 is provided with a cleaning plate 402. The width of the cleaning plate 402 is smaller than the pitch of the spiral blade 103.

[0040] It should be noted that the cleaning mechanism wipes away the dirt adhering to the spiral blades 103, ensuring the cleanliness of the spiral blades 103, preventing the spiral blades 103 from rusting due to the dirt, and maintaining the normal service life of the spiral drill bit.

[0041] Specifically, the cleaning plate 402 is provided with an auxiliary mechanism to ensure that the upper and lower side walls of the spiral blade 103 are cleaned simultaneously. The auxiliary mechanism includes an auxiliary groove 501 opened on the cleaning plate 402, a rubber airbag 502 is provided on the auxiliary groove 501, and an inflation mechanism for inflating the rubber airbag 502 is provided on the cleaning plate 402.

[0042] It should be noted that the auxiliary mechanism facilitates the simultaneous cleaning and wiping of the upper and lower side walls of the spiral blade 103, which improves the cleaning effect of the spiral blade 103 and ensures the cleaning quality of the spiral blade 103.

[0043] Specifically, the inflation mechanism includes an inflation box 601 fixedly connected to the cleaning plate 402. The inflation box 601 is provided with an air inlet pipe, which is connected to the rubber airbag 502. A sliding plate 602 is slidably connected to the side wall of the cleaning plate 402. A push plate 603 is provided on the side of the sliding plate 602 near the inflation box 601. A piston plate is provided at one end of the push plate 603 inside the inflation box 601. The cleaning plate 402 is provided with a push mechanism for pushing the sliding plate 602.

[0044] It should be noted here that the inflation mechanism facilitates the inflation of the rubber airbag 502.

[0045] Specifically, the pushing mechanism includes a second fixed plate 701 fixedly connected to the side wall of the cleaning plate 402, a first motor 702 mounted on the second fixed plate 701, a third fixed plate 703 mounted on the cleaning plate 402, a rotating rod 704 mounted on the third fixed plate 703, the rotating rod 704 being connected to the output end of the first motor 702, a fixing ring 705 mounted on the side wall of the rotating rod 704, a plurality of pushing tubes 706 rotatably connected to the fixing ring 705, a pushing rod 707 slidably connected to each pushing tube 706, a pushing ball 708 mounted at one end of each pushing rod 707, each pushing ball 708 sliding on the side wall of the sliding plate 602, and a second spring mounted on the bottom wall of each pushing tube 706, the other end of the second spring being connected to the pushing rod 707;

[0046] It should be noted that the setting of the pushing mechanism facilitates the injection of gas from the air inlet of the air box 601 into the rubber air bag 502, causing the rubber air bag 502 to expand. The expanded rubber air bag 502 will then abut against the upper and lower side walls of the spiral blade 103.

[0047] Specifically, the rotating rod 704 is equipped with a fan blade 709 at one end near the auger bit;

[0048] It should be noted that during the rotation of the first motor 702, the fan blade 709 at one end of the rotating rod 704 will rotate. During the rotation of the fan blade 709, air will be continuously blown onto the spiral blade 103 to dry the moisture on the spiral blade 103, further preventing the risk of corrosion of the spiral blade 103.

[0049] Specifically, the sliding plate 602 is provided with a reset mechanism to facilitate the reset of the air box 601. The reset mechanism includes a reset rod 803 fixedly connected to the sliding plate 602, a reset tube 802 sleeved on the side wall of the reset rod 803, a fourth fixing plate 801 provided on the side wall of the air box 601, one end of the reset tube 802 connected to the fourth fixing plate 801, a third spring provided on the bottom wall of the reset tube 802, and the other end of the third spring connected to the reset rod 803.

[0050] It should be noted here that: by setting up a reset mechanism, after the spiral blade 103 is cleaned, the rotation of the first motor 702 is stopped. At this time, under the elastic force of the third spring, the sliding plate 602 will be reset, so that the piston plate will draw the gas in the rubber airbag 502 back into the inflation box 601. The rubber airbag 502, which has lost gas support, will retract back into the auxiliary groove 501.

[0051] Specifically, the drive mechanism includes two drive tubes 901 fixedly connected to the side wall of the first fixed plate 401. One of the two drive tubes 901 is slidably connected to a guide rod 902. One end of the guide rod 902 is connected to the U-shaped plate 205. The other drive tube 901 is threadedly connected to a threaded rod 903. A second motor 904 is provided on the U-shaped plate 205. One end of the threaded rod 903 is connected to the output end of the second motor 904.

[0052] It should be noted here that the drive mechanism facilitates the movement of the cleaning plate 402 towards or away from the spiral blade 103.

[0053] Specifically, a construction method for a soil drilling rig used in municipal engineering construction includes the following steps:

[0054] S1: Hold the handles 105 on the control panel 101 with both hands, move the auger bit to the location where drilling is required, and after reaching the drilling location, place the U-shaped plate 205 against the ground and make fine adjustments to the U-shaped plate 205 so that the bubble on the level 206 on the control panel 101 is in the center position.

[0055] S2: During the drilling process, pay attention to whether the bubble on the level 206 is in the center position, and adjust it in time according to the situation of the bubble on the level 206 to ensure that the auger drill bit is always perpendicular to the ground when drilling.

[0056] S3: After drilling to the required depth, stop the rotation of the reducer 104, thereby stopping the rotation of the auger drill bit. Under the driving action of the drive mechanism, the cleaning plate 402 enters the auger blade 103.

[0057] S4: The gas in the inflation box 601 is injected into the rubber air bag 502 through the inflation mechanism, causing the rubber air bag 502 to expand. The expanded rubber air bag 502 will abut against the upper and lower side walls of the spiral blade 103.

[0058] S5: When the rubber airbag 502 abuts against the upper and lower side walls of the spiral blade 103, the reducer 104 is started again to drive the spiral drill bit to rotate. By pulling the handle 105 upward, the spiral drill bit is gradually moved out of the hole. During the process of the spiral drill bit being moved out of the hole, the mud attached to the spiral blade 103 will be wiped clean by the rubber airbag 502 wiping the spiral blade 103.

[0059] Working principle: When drilling soil for municipal engineering, hold the handles 105 on the control panel 101 with both hands and move the auger bit to the location where drilling is required. After reaching the drilling location, place the U-shaped plate 205 against the ground and make fine adjustments to the U-shaped plate 205 so that the bubble on the level 206 on the control panel 101 is in the center position. At this time, start the reducer 104 to drive the auger bit to start drilling. During the drilling process, pay attention to whether the bubble on the level 206 is in the center position and adjust it in time according to the status of the bubble on the level 206 so that the auger bit is always perpendicular to the ground when drilling, thereby ensuring the verticality of the drilled hole, which not only improves the aesthetics of subsequent tree planting, but also increases the safety of pile embedding operation.

[0060] After drilling to the required depth, the rotation of the reducer 104 is stopped, thereby stopping the rotation of the auger drill bit. At this time, the second motor 904 is started, driving the threaded rod 903 to rotate. Under the threaded meshing transmission between the threaded rod 903 and the drive tube 901 and the guiding action of the guide rod 902, the cleaning plate 402 on the first fixed plate 401 is driven to move closer to the auger blade 103. After the cleaning plate 402 enters the auger blade 103, the rotation of the second motor 904 is stopped.

[0061] The first motor 702 is started, which drives the fixed ring 705 on the rotating rod 704 to rotate. During the rotation of the fixed ring 705, under the action of centrifugal force, each pushing ball 708 is driven to move towards the sliding plate 602, thereby pushing the pushing plate 603 on the sliding plate 602 to move into the air box 601. During the movement of the pushing plate 603 into the air box 601, the piston plate is pushed to move within the air box 601, further injecting the gas in the air box 601 into the rubber air bag 502 through the air inlet pipe, causing the rubber air bag 502 to expand. The expanded rubber air bag 502 will abut against the upper and lower side walls of the spiral blade 103.

[0062] When the rubber airbag 502 abuts against the upper and lower side walls of the spiral blade 103, the reducer 104 is started again to drive the spiral drill bit to rotate. By pulling the handle 105 upward, the spiral drill bit is gradually moved out of the hole. During the process of the spiral drill bit being moved out of the hole, the rubber airbag 502 wipes the spiral blade 103, cleaning the dirt attached to the spiral blade 103, ensuring the cleanliness of the spiral blade 103, preventing the spiral blade 103 from rusting due to the dirt, and maintaining the normal service life of the spiral drill bit.

[0063] Furthermore, during the rotation of the first motor 702, the fan blade 709 at one end of the rotating rod 704 will rotate. During the rotation of the fan blade 709, air will be continuously blown onto the spiral blade 103 to dry the moisture on the spiral blade 103, further preventing the risk of corrosion of the spiral blade 103.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention. Technical aspects, shapes, and structures not described in detail in this invention are all well-known technologies.

S4: The gas in the inflation box (601) is injected into the rubber air bag (502) by the inflation mechanism, so that the rubber air bag (502) expands under the air and the expanded rubber air bag (502) will abut against the upper and lower side walls of the spiral blade (103). S5: When the rubber airbag (502) abuts against the upper and lower side walls of the spiral blade (103), the reducer (104) is started again to drive the spiral drill bit to rotate. By pulling the handle (105) upward, the spiral drill bit is gradually moved out of the hole. During the process of the spiral drill bit being moved out of the hole, the soil attached to the spiral blade (103) will be wiped clean by the rubber airbag (502) wiping the spiral blade (103).
