Description

Technical Field

[0001] The present application relates to the field of drilling equipment, and in particular to a ground drilling machine with an adjustable handrail. Background Art

[0002] The ground boring machine is a special drilling equipment commonly used for planting trees, fertilizing and afforestation in mountainous areas, hills, and gully areas.

[0003] The existing ground boring machine generally includes a base, a bracket, a hand lever, a drill rod and a drill rod driving device. The bracket body is hinged on the base, the hand lever and the drill rod are arranged at one end of the bracket relatively up and down, and the drill rod driving device is connected to the drill rod and can drive the drill rod to rotate with the cutter head at the bottom of the drill rod, so that the user can apply downward pressure to the drill rod by holding and pressing down the hand lever, thereby enabling the drill rod and the cutter head to drill a hole in the ground.

[0004] However, as the drill rod moves downward in the hole it has drilled, the distance between the handrail and the ground will continue to decrease, requiring the user to bend down as the handrail moves downward in order to continue holding the handrail, making the operation of the earth drilling machine very inconvenient.

[0005] In view of this, it is necessary to provide a ground boring machine with an adjustable handrail. Utility Model Content

[0006] In order to solve the problem that the existing earth boring machine requires the user to bend down during the drilling process, which is very inconvenient to operate, the present application provides an earth boring machine with an adjustable handrail.

[0007] The present application provides a ground drilling machine with an adjustable handrail, which adopts the following technical solution: comprising a frame, a drill rod, a drive assembly, a handrail and a clamping assembly, wherein the frame comprises a support and a crossbeam, and the crossbeam is hinged at the top of the support;

[0008] The drill rod is arranged at one end of the cross beam away from the support column, and a cutter head is arranged at the bottom end of the drill rod;

[0009] The driving assembly is in driving connection with the drill rod and can drive the drill rod to drive the cutter head to rotate;

[0010] The handrail comprises a hinged section and a gripping section, a handrail hinge shaft is provided on the beam body of the crossbeam, the hinged section is hinged on the handrail hinge shaft, and the gripping section can rotate around the handrail hinge shaft to approach or move away from the drill rod;

[0011] One side of the clamping component is connected to the handrail, and the other side of the clamping component is detachably connected to the cross beam. Moreover, the clamping component can restrict the rotation of the handrail when connected to the cross beam.

[0012] By adopting the above technical solution, the user can first disassemble the connection between the clamping component and the cross beam, then rotate the holding section of the handrail towards or away from the drill rod to adjust the distance between the holding section and the drill rod. Finally, connect the clamping component to the cross beam and restrict the rotation of the handrail, so that the user can rotate the handrail during the process of using the automatic drilling machine to keep the holding section of the handrail at a position with a certain distance from the ground, so that the user does not need to bend down together with the downward movement of the drill rod to maintain the posture of holding the handrail, thus facilitating the drilling operation of the ground drilling machine.

[0013] Specifically, the clamping component includes a bent rod, a limiting sleeve and a pull rod. The middle part of the bent rod is hinged on the rod body of the handrail. A plurality of clamping holes are formed in the beam body of the cross beam around the handrail hinge shaft. A hook adapted to the clamping hole is provided at one end of the bent rod. A waist-shaped hole is provided on the rod body at the other end of the bent rod along the direction of approaching or departing from the handrail hinge shaft. The limiting sleeve is connected to the handrail, and the length direction of the limiting sleeve is inclined to the length direction of the waist-shaped hole. The pull rod is inserted into the limiting sleeve. A sliding rod is provided at one end of the pull rod. The sliding rod passes through the waist-shaped hole and abuts against the inner wall of the waist-shaped hole. The other end of the pull rod can slide along the inner wall of the limiting sleeve towards or away from the waist-shaped hole, and drive the bent rod to rotate around its own hinge shaft and drive the hook to depart from or insert into the clamping hole.

[0014] By adopting the above technical solution, the user can slide the pull rod along the limiting sleeve away from the waist-shaped hole, so that the sliding rod at the end of the pull rod abuts against the inner wall of the waist-shaped hole and drives the bent rod to rotate around its own hinge shaft, and then the hook connected to the bent rod is pulled out from the clamping hole on the cross beam, so that the user can rotate the handrail towards or away from the drill rod. After adjusting the holding section of the handrail to an appropriate height, the user can slide the pull rod along the limiting sleeve towards the waist-shaped hole, so that the sliding rod drives the bent rod to rotate and drives the hook to insert into the clamping hole corresponding to this height, thereby being able to fix the handrail.

A hydraulic circuit for circulating hydraulic oil is formed by connecting the liquid outlet of the hydraulic pump and the liquid inlet of the hydraulic motor and between the liquid inlet of the hydraulic pump and the liquid outlet of the hydraulic motor through pipelines.

[0018] By adopting the above technical solution, the hydraulic pump can provide hydraulic energy to the hydraulic motor, and the hydraulic motor can convert the received hydraulic energy into the mechanical energy of the output shaft of the hydraulic motor, and then drive the drill pipe to rotate through the hydraulic motor.

[0019] Further, the driving assembly further includes a thermometer, and the thermometer is arranged on the support column and can detect the temperature of the hydraulic oil in the hydraulic circuit.

[0020] By adopting the above technical solution, the user can detect the temperature of the hydraulic oil in the hydraulic circuit through the thermometer.

[0021] Further, the driving assembly further includes a liquid level gauge and an oil pot for containing hydraulic oil. The liquid level gauge is arranged on the support column and can detect the amount of hydraulic oil in the hydraulic circuit, and the oil pot is connected to the hydraulic circuit.

[0022] By adopting the above technical solution, the user can observe the amount of hydraulic oil in the hydraulic circuit through the liquid level gauge, and replenish the hydraulic circuit with oil through the oil pot when the amount of hydraulic oil is too low.

[0023] Specifically, a spiral body is provided on the rod body of the drill pipe, and the rotating shaft of the spiral body is the central axis of the drill pipe.

[0024] By adopting the above technical solution, after the cutter head at the bottom of the drill pipe digs out the soil, the spiral body can transport the soil upward and discharge it from the hole opening of the hole drilled by the drill pipe.

[0025] Specifically, a pair of wheels are rotatably connected to the bottom end of the support column.

The compression springs 54 on each pull rod 53 will drive the pull rod 53 to slide along the limiting sleeve 52 in the direction close to the waist-shaped hole 512, so that the sliding rod 531 drives the bent rod 51 to rotate and drives the hook 511 to insert into the clamping hole 122, so as to fix the handrail 4.

[0040] The working principle of a ground drilling machine with an adjustable handrail of this application during use is specifically as follows:

[0041] The user can hold the connecting rod by hand to slide the two pull rods 53 away from the kidney-shaped hole 512 along their respective limit sleeves 52, so that the sliding rod 531 at the end of the pull rod 53 abuts against the inner wall of the kidney-shaped hole 512 and drives the bent rod 51 to rotate around its own hinge axis. Subsequently, the hook 511 connected to the bent rod 51 is pulled out from the clamping hole 122 on the cross beam 12, so that the user can rotate the handrail 4 towards or away from the drill rod 2. After adjusting the holding section 42 of the handrail 4 to an appropriate height and aligning the two hooks 511 with the clamping holes 122 corresponding to this height, the user can release the connecting rod. The compression springs 54 on each pull rod 53 will drive the pull rod 53 to slide along the limit sleeve 52 towards the kidney-shaped hole 512, so that the sliding rod 531 drives the bent rod 51 to rotate and drives the hook 511 to insert into the clamping hole 122, thereby being able to fix the handrail 4. When the user uses the automatic drilling machine to drill a hole, the user can rotate the handrail 4 so that the holding section 42 of the handrail 4 can be kept at a position with a certain distance from the ground, so that the user does not need to bend down together with the downward movement of the drill rod 2 to maintain the posture of holding and pressing the handrail 4, thus facilitating the drilling operation of the ground drilling machine.
