[0018] (2) The present invention is provided with a flipping device. When drilling, the sliding of the sliding block drives the hinged rod to rotate, further causing the saw plate to slide upward. When the saw plate slides upward, it drives the saw teeth to rotate, thereby driving the flipping plate to rotate, so that the flipping plate pushes the soil thrown onto the ground during drilling away from the drilling well, thereby solving the problem that after the drilling work is completed, the soil is easy to collapse and fall into the drilling well again when the drill rod is pulled out, causing the drilling well to be blocked, and it can prevent the soil drilled out by the drill rod from accumulating at the drilling well and the drill rod, so that the drill rod can be prevented from being stuck in the drilling well.

When the sliding plate slides, it drives the cleaning rod to move, thereby scraping off the soil on the outer wall of the flip plate, solving the problem that the flip plate is easily stuck to the soil when it is pushed away from the soil, and may fall around the drilling again when the flip plate is reset.

[0019] (3) The present invention is provided with a pushing device. When the flip plate pushes the soil away from the periphery of the drilling well, the fixed rod drives the rotating block to rotate, causing the top rod to slide. When the top rod slides, it drives the push rod to rotate. The rotation of the push rod drives the connecting rod to rotate, and further drives the push plate to rotate, thereby pushing the flip plate away from the soil around the drilling well and further pushing away the soil. This solves the problem that when the flip plate pushes the soil to the periphery of the rolling wheel, it is easy to block the rolling wheel, further affecting the movement of the equipment.

The motor 5 moves downward to the pressure plate 72 to push the pressure plate 72 to move downward. The inclined surface block 73 is fixedly connected to the bottom surface of the pressure plate 72. When the pressure plate 72 moves downward, the inclined surface block 73 is driven to move downward. A sliding groove is provided on the upper surface of the base 1. The outer wall of the sliding block 74 is slidably connected to the inner wall of the sliding groove. When the inclined surface block 73 moves downward to contact the sliding block 74, the sliding groove drives the sliding block 73 to move downward. The movable block 74 slides in the direction away from the drill rod 6, the knocking block 75 is fixedly connected to the side wall of the sliding block 74 close to the drill rod 6, and the driven rod 76 is fixedly connected to the side wall of the sliding block 74. When the sliding block 74 slides in the direction away from the drill rod 6, the driven rod 76 is driven to move together, and the air storage chamber 77 is fixedly connected to the upper surface of the base 1, the lower end of the first spring 78 is fixedly connected to the upper surface of the base 1, the outer wall of the first spring 78 is fitted with the inner wall of the air storage chamber 77, the upper end of the first spring 78 is fixedly connected to the bottom surface of the pressing block 79, and the pressing block 79 compresses the first spring 78 when it slides downward, and the side wall of the pressing block 79 is slidably connected to the inner wall of the air storage chamber 77, and the driven rod 7 When the pressing block 79 moves to the pressing block 79, the pressing block 79 is pushed to slide downward. When the pressing block 79 slides downward against the inner wall of the air storage chamber 77, the air inside the air storage chamber 77 is quickly pushed out to blow air to the drill rod 6. When the knocking device is drilling, the pressing plate 72 is driven downward by the downward movement of the motor 5. When the pressing plate 72 moves downward, the inclined block 73 is driven downward. When the inclined block 73 moves downward, the sliding block 74 is pushed away from the drill rod 6. After the drilling is completed, the gravity of the saw plate 82 drives the hinged rod 81 to rotate, pushing the sliding block 74 to slide quickly in the direction of the drill rod 6. When the sliding block 74 slides to the top of the sliding groove, it drives the knocking block 75 to hit the drill rod. 6, thereby knocking the drill rod 6 and knocking off the sticky soil on the outer wall of the drill rod 6, solving the problem that the outer wall of the drill rod 6 is prone to affect the drilling efficiency due to the large amount of soil; the sliding block 74 drives the driven rod 76 to move when sliding, and the driven rod 76 pushes the pressing block 79 to slide downward in accordance with the inner wall of the air storage chamber 77 when moving, compressing the air inside the air storage chamber 77, pushing the air inside the air storage chamber 77 out of the air storage chamber 77, blowing air on the outer wall of the drill rod 6, accelerating the air flow speed around the drill rod 6, thereby accelerating the evaporation of moisture in the soil on the outer wall of the drill rod 6, and controlling the soil to dry, solving the problem that the wet soil is too sticky, resulting in the inability of the knocking block 75 to knock off the soil.

[0032] When the present embodiment is working, the motor 5 is started, the motor 5 drives the drill rod 6 to rotate, and the L-shaped rod 4 is controlled to rise and fall by the cylinder 3 to control the drilling depth. The L-shaped rod 4 drives the motor 5 to rise and fall together. When the drilling reaches a certain depth, the motor 5 moves downward to the pressure plate 72, pushing the pressure plate 72 to move downward. When the pressure plate 72 moves downward, it drives the inclined surface block 73 to move downward. When the inclined surface block 73 moves downward to contact the sliding block 74, it pushes the sliding block 74 to slide in the direction away from the drill rod 6. When the sliding block 74 slides in the direction away from the drill rod 6, it drives the driven rod 76 to move together. When the driven rod 76 moves to the pressure block 79, it pushes the pressure block 79 to slide downward and compresses the first spring 78. When the pressure block 79 slides downward against the inner wall of the air storage chamber 77, the air inside the air storage chamber 77 is quickly pushed out to blow air to the drill rod 6. When the driven rod 76 moves to leave the pressure block 79, When the sliding block 74 slides in the direction of the drill rod 6, it drives the hinged rod 81 to rotate. When the hinged rod 81 rotates, it drives the saw plate 82 to slide upward. When drilling is completed, the cylinder 3 controls the L-shaped rod 4 to drive the motor 5 and the drill rod 6 to move upward. At the same time, due to the influence of gravity, it slides downward. When the saw plate 82 slides downward, it drives the hinged rod 81 to rotate. When the hinged rod 81 rotates clockwise, it drives the sliding block 74 to slide in the direction of the drill rod 6. When the sliding block 74 slides in the direction of the drill rod 6, it pushes the pressing block 79 to slide downward again to blow air to the drill rod 6, thereby reducing the humidity of the soil on the outer wall of the drill rod 6. When the sliding block 74 slides to the top of the sliding groove, the knocking block 75 on the side wall of the sliding block 74 hits the drill rod 6, knocking off the soil on the outer wall of the drill rod 6.

[0033] See also Figure 1-Figure 8On the basis of the above-mentioned embodiment, in another embodiment of the present invention, a turning device for preventing the drilled soil from clogging the drilling well is provided on the bottom surface of the base 1, and the turning device comprises an articulated rod 81, a saw plate 82, a limit block 83, a turning plate 84, saw teeth 85, a fixed gear 86, a driven gear 87, a rotating rod 88, a sliding plate 89, a protrusion 810, a slide groove 811 and a cleaning rod 812. The lower end of the articulated rod 81 is hinged to the side wall of the sliding block 74 away from the drill rod 6. When the sliding block 74 slides in the direction away from the drill rod 6, the articulated rod 81 is pushed to rotate. The saw plate 82 penetrates the base 1 and is slidably connected at the penetration point. The upper end of the articulated rod 81 is articulated to the side wall of the saw plate 82. When the articulated rod 81 rotates, the saw plate 82 is driven to slide upward. The limit block 83 is fixedly connected to the base 1. The bottom surface of the base 1, the upper end of the flip plate 84 is hinged on the bottom surface of the limit block 83, the sawtooth 85 is fixedly connected to the outer wall of the upper end of the flip plate 84, the sawtooth 85 is meshed with the saw plate 82, and when the saw plate 82 slides upward, the flip plate 84 is driven to rotate by the meshed sawtooth 85, so that the soil drilled out of the drill pipe 6 is pushed away from the periphery of the drilling well, the fixed gear 86 is fixedly connected to the side wall of the limit block 83, and the driven gear 87 is rotatably connected to the side wall of the flip plate 84. When the flip plate 84 rotates, the driven gear 87 is driven to rotate around the hinge point between the flip plate 84 and the limit block 83, and the rotating rod 88 is fixedly connected to the side wall of the driven gear 87. When the driven gear 87 rotates, it drives the rotating rod 88 to rotate, and the driven gear 87 is meshed with the fixed gear 86. The driven gear 87 is meshed with the fixed gear 86 on the outer wall of the limit block 83, so when the driven gear 87 rotates around the hinge point, it also rotates. The rotating rod 88 passes through the flip plate 84 and is rotatably connected at the penetration point. The rotating rod 88 passes through the sliding plate 89 and is fitted at the penetration point. The protrusion 810 is fixedly connected to the inner wall of the sliding plate 89. When the protrusion 810 slides, it drives the sliding plate 89 to slide along the rotating rod 88. The sliding groove 811 is opened on the outer wall of the rotating rod 88. When the rotating rod 88 rotates, it drives the sliding groove 811 to rotate. The outer wall of the protrusion 810 and the inner wall of the sliding groove 811 are fitted. Since the outer wall of the protrusion 810 is fitted thereto, the protrusion 810 slides along the sliding groove 811 when the sliding groove 811 rotates. The sliding plate 89 and the inner wall of the flip plate 84 are slidably connected. The cleaning rod 812 is fixedly connected to the end of the sliding plate 89 away from the rotating rod 88. When the sliding plate 89 slides, it drives the cleaning rod 812 to move, and scrapes off the sticky soil when the flip plate 84 pushes the soil away. When drilling, the flipping device drives the hinged rod 81 to rotate through the sliding of the sliding block 74, and further causes the saw plate 82 to slide upward. When the saw plate 82 slides upward, it drives the saw teeth 85 to rotate, thereby driving the flip plate 84 to rotate, so that the flip plate 84 pushes the soil thrown onto the ground during drilling away from the drilling well, which solves the problem that after the drilling work is completed, the soil is easy to collapse and fall into the drilling well again when the drill rod 6 is pulled out, causing the drilling well to be blocked, and it can prevent the soil drilled out of the drill rod 6 from accumulating at the drilling well and the drill rod 6, so that when the drill rod 6 moves at the drilling well,This can easily cause the drilled soil to adhere to the drill rod 6.

[0034] When the flip plate 84 rotates, it drives the driven gear 87 to rotate around the fixed gear 86 and rotate at the same time. When the driven gear 87 rotates, it drives the rotating rod 88 to rotate, and cooperates with the protrusion 810 and the slide groove 811 to make the sliding plate 89 slide on the inner wall of the flip plate 84. When the sliding plate 89 slides, it drives the cleaning rod 812 to move, thereby scraping off the soil on the outer wall of the flip plate 84, solving the problem that the flip plate 84 is easily stuck to the soil when it is pushed away from the soil, and may fall around the drilling again when the flip plate 84 is reset.

[0035] The bottom surface of the base 1 is provided with a pushing device to prevent soil from blocking the movement of the equipment. The pushing device includes a limit plate 91, a rotating block 92, a top rod 93, a connecting rod 94, a push plate 95 and a push rod 96. The limit plate 91 is fixedly connected to the bottom surface of the base 1. A fixed rod is fixed to the outer wall of the hinge between the flip plate 84 and the limit block 83. When the flip plate 84 rotates, the fixed rod is driven to rotate. The fixed rod passes through the limit block 83 and the fixed gear 86, and the penetration is rotatably connected. The rotating block 92 is fixedly connected to the fixed rod away from the flip plate 84. When the fixed rod rotates, the rotating block 92 is driven to rotate together, and the top rod 93 penetrates the limit plate 91 and is slidably connected at the penetration point. When the rotating block 92 rotates, the top rod 93 is pushed to slide in the direction of the limit plate 91. A fixed plate is fixed to the outer wall of the limit plate 91, and the fixed plate is fixedly connected to the left end of the second spring, and the right end of the second spring is fixedly connected to the side wall of the limit plate 91. When the top rod 93 slides in the direction of the limit plate 91, the second spring is compressed, and the connecting rod 94 is rotatably connected to the bottom surface of the base 1, and the push plate 95 is fixedly connected The push rod 96 is connected to the bottom end of the connecting rod 94. When the connecting rod 94 rotates, the push plate 95 is driven to rotate, and the flip plate 84 is pushed away from the drilling soil to a position away from the rolling wheel 2. The push rod 96 is fixedly connected to the outer wall of the connecting rod 94. Since the push rod 96 is fixedly connected to the connecting rod 94, when the push rod 96 rotates, the connecting rod 94 is also driven to rotate. The side wall of the push rod 96 is slidably connected to the end of the push rod 93 away from the rotating block 92. When the push rod 93 slides in the direction of the limit plate 91, it pushes the push rod 96 around the center of the connecting rod 94 The shaft rotates, and when the flip plate 84 pushes the soil away from the periphery of the drilling well, the pushing device drives the rotating block 92 to rotate through the fixed rod, causing the top rod 93 to slide. When the top rod 93 slides, it drives the push rod 96 to rotate, and the rotation of the push rod 96 drives the connecting rod 94 to rotate, and further drives the push plate 95 to rotate, thereby pushing the flip plate 84 away from the soil around the drilling well and further pushing away the soil, solving the problem that the flip plate 84 is likely to block the rolling wheel 2 when pushing the soil to the periphery of the rolling wheel 2, further affecting the movement of the equipment.

[0036] When the present embodiment is working, when the saw plate 82 slides upward, the saw teeth 85 meshing with it drive the flip plate 84 to rotate, and the soil drilled out of the drill pipe 6 is pushed away from the periphery of the drilling well. When the flip plate 84 rotates, the driven gear 87 is driven to rotate around the hinge point between the flip plate 84 and the limit block 83. Since the driven gear 87 is meshed with the fixed gear 86 on the outer wall of the limit block 83, the driven gear 87 also rotates when it rotates around the hinge point. When the driven gear 87 rotates, it drives the rotating rod 88 to rotate. When the rotating rod 88 rotates, it drives the slide groove 811 to rotate. Since the outer wall of the protrusion 810 is in contact with it, the protrusion 810 slides along the slide groove 811 when the slide groove 811 rotates. When the protrusion 810 slides, it drives the sliding plate 89 to slide along the rotating rod 88. When the sliding plate 89 slides, it drives the cleaning rod 812 to move, and the sticky soil of the flip plate 84 is scraped off when the soil is pushed away.

[0037] When the flip plate 84 rotates, it drives the fixed rod to rotate, and when the fixed rod rotates, it drives the rotating block 92 to rotate together. When the rotating block 92 rotates, it pushes the push rod 93 to slide in the direction of the limit plate 91. When the push rod 93 slides in the direction of the limit plate 91, the second spring is compressed, and at the same time, the push rod 96 is pushed to rotate around the central axis of the connecting rod 94. Since the push rod 96 is fixedly connected to the connecting rod 94, when the push rod 96 rotates, it drives the connecting rod 94 to rotate as well. When the connecting rod 94 rotates, it drives the push plate 95 to rotate, pushing the flip plate 84 away from the drilling soil to a position away from the rolling wheel 2.
