Technical Field

[0001] The utility model relates to the technical field of rotary drilling machines, in particular to a fish scale pit rotary drilling machine. Background Art

[0002] Fish scale pit rotary drilling machine is a type of trenching equipment. It can dig fish scale-shaped holes in the ground through the work of the spiral drill bit inside the equipment. It is mainly used in forest planting and vegetation restoration operations.

[0003] When the rotary drilling rig is working, the spiral drill bit can be controlled up and down by the control arm. The pit digging operation can be carried out by rotating the spiral drill bit and cooperating with the drill bit installed below. The spiral drill bit is generally an integrated structure and cannot be spliced ​​in blocks. In this way, when the spiral drill bit is severely worn and needs to be replaced, the staff needs to replace the entire spiral drill bit, and the damaged part cannot be replaced separately, which is very inconvenient to use. For this reason, we propose the fish scale pit rotary drilling rig. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a fish scale pit rotary drilling machine, including a rotary drilling machine body 1, the outside of the rotary drilling machine body 1 is connected to a control arm 2, the outside of the control arm 2 is installed with a connecting frame 3, the inside of the connecting frame 3 is connected with a first connecting shaft 4, the rotary drilling machine body 1 can control the position of the first connecting shaft 4 through the control arm 2, and a control motor is provided inside the connecting frame 3, which can control the rotation of the first connecting shaft 4 through the control motor, thereby further controlling the rotation of the spiral blade 7 and the drill bit 21.

[0022] The internal thread of the first connecting shaft 4 is connected to a connecting head 5, and the lower surface of the connecting head 5 is connected to the second connecting shaft 6. The first connecting shaft 4 and the second connecting shaft 6 can be connected through the connecting head 5. The outer surfaces of the first connecting shaft 4 and the second connecting shaft 6 are connected with spiral blades 7. The spiral line directions of the spiral blades 7 on the first connecting shaft 4, the second connecting shaft 6 and the connecting shaft extended below are the same, which can ensure the neatness of the texture when excavating the fish scale pit.

[0023] The outer surface of the first connecting shaft 4 is connected to a fixing ring 8, and a fixing hole 9 is opened inside the fixing ring 8. The outer surface of the second connecting shaft 6 is connected to a fixing ring 2 10. The interior of the fixing ring 2 10 is slidingly connected to multiple groups of limit rods 11. The outer surface of the limit rod 11 is slidingly connected to the interior of the fixing hole 9. When the first connecting shaft 4 and the second connecting shaft 6 are connected, the limit rod 11 will enter the interior of the fixing hole 9. At this time, the first connecting shaft 4 and the second connecting shaft 6 can be stably connected. The limit rod 11 can support the axial direction of the second connecting shaft 6. When the first connecting shaft 4 and the second connecting shaft 6 rotate, the limit rod 11 can auxiliary support and fix the connector 5, which can ensure the stability of the connector 5 when connected.

[0024] The lower surface of the limiting rod 11 is connected to the base plate 12. The interior of the fixing ring 10 is provided with multiple groups of limiting grooves 14 arranged in a circular array. The outer surface of the base plate 12 is slidably connected to the interior of the limiting groove 14. The limiting groove 14 can limit the position of the base plate 12. The base plate 12 will slide inside the limiting groove 14, and can drive the limiting rod 11 to move inside the fixing ring 10.

[0025] The lower surface of the base plate 12 is connected with a clamping bolt 13, and the threaded end of the clamping bolt 13 contacts the lower surface of the base plate 12. The clamping bolt 13 can push the base plate 12 to move, and can push the limiting rod 11 into the interior of the fixing hole 9. The inner wall of the limiting groove 14 is connected with a support plate 15, and the outer surface of the clamping bolt 13 is connected to the internal thread of the support plate 15. The support plate 15 and the clamping bolt 13 are provided with multiple groups and arranged in an array. The support plate 15 can ensure the stability of the clamping bolt 13 when fixed and supported. After the clamping bolt 13 is tightened, the bottom will enter the interior of the limiting groove 14, which has a protective effect on the clamping bolt 13.

[0026] A return spring 16 is installed on the upper surface of the support plate 15, and the other end of the return spring 16 is connected to the lower surface of the base plate 12. When the damaged spiral blade 7 is replaced, the clamping bolt 13 is rotated to make the clamping bolt 13 disengage from the contact with the fixing ring 2 10. At this time, the return spring 16 will drive the base plate 12 to move toward the support plate 15. At this time, the limit rod 11 will move toward the inside of the fixing ring 2 10, and the limit rod 11 will disengage from the contact with the fixing hole 1 9. At this time, the damaged part can be disassembled and replaced through the connector 1 5.

[0027] The outer surface of the second connecting shaft 6 is connected to a fixing ring three 17, and a fixing hole two 18 is opened inside the fixing ring three 17. The interior of the fixing hole two 18 is slidably connected to multiple groups of fixing bolts 19. The next group of connecting shafts can be connected through the fixing ring two 10 and the fixing hole two 18, and the length of the entire connecting shaft can be extended to meet the construction requirements of more fish scale pits.

[0028] The bottom end of the second connecting shaft 6 is threadedly connected to a connecting head 20, and the lower surface of the connecting head 20 is connected to a drill bit 21. The outer surfaces of multiple sets of fixing bolts 19 are threadedly connected to the interior of the drill bit 21. The drill bit 21 can be easily replaced through the connecting head 20. After the drill bit 21 is installed, the fixing bolts 19 will enter the interior of the drill bit 21, which can assist in fixing the drill bit 21 and improve the stability of the drill bit 21 during use.

[0029] When replacing a damaged spiral blade 7, first release the contact between the clamping bolt 13 and the support plate 15. Under the pull of the reset spring 16, the bottom plate 12 will move downward. At this time, the bottom plate 12 will drive the limiting rod 11 to break away from the contact with the fixing hole 9. The connecting shaft of the damaged part can be disassembled through the connecting head 5, which is convenient for replacing the damaged part separately. During installation, the first connecting shaft 4 and the second connecting shaft 6 are connected through the connecting head 5. At this time, the clamping bolt 13 is installed inside the support plate 15. The clamping bolt 13 will further push the limiting rod 11 into the inside of the fixing hole 9. The first connecting shaft 4 and the second connecting shaft 6 can be auxiliary fixed through the limiting rod 11 and the fixing hole 9.
