Description
Technical Field
[0001] The utility model belongs to the technical field of coal mine devices, and particularly relates to a drill bit unloading device. Background Art
[0002] At present, the drill bit of underground drilling rig is removed by manually hitting it with a sledgehammer to loosen the thread, and then removing the drill bit with a pipe clamp, which is labor-intensive and inefficient.
[0003] The original drill bit removal device mainly uses a sledgehammer to manually remove the drill bit using a pipe clamp. During the construction of the gangue hole, the drill bit thread becomes increasingly tight and difficult to remove, which is both labor-intensive and time-consuming. Utility Model Content

[0005] The utility model adopts the following technical solutions:
[0006] A drill bit unloading device includes connecting rod 1, connecting rod 2 and connecting rod 3. One end of connecting rod 1 is provided with opening 1, and the other end is provided with clamping device 1 for clamping the drill bit. One end of connecting rod 2 is provided with opening 2, and the other end is provided with clamping device 2 for clamping the drill bit. Both ends of connecting rod 3 are respectively provided with external threads. The two ends of connecting rod 3 with external threads are respectively threadedly connected with sleeves, and the sleeves are respectively connected to opening 1 and opening 2 through connecting rod 1 and connecting rod 2.
[0007] Furthermore, the clamping device 1 and the clamping device 2 both include a clamping hook 1, a clamping hook 2 and a clamping hook 3, one end of the clamping hook 1 is hinged to one end of the connecting rod 1 or the connecting rod 2, and the other end is hinged to one end of the clamping hook 2, the other end of the clamping hook 2 is hinged to one end of the clamping hook 3, and the other end of the clamping hook 3 is provided with a cross bar, and the connecting rod 1 or the connecting rod 2 is clamped to the clamping hook 3 through the cross bar.
[0008] Furthermore, a circular hole is provided at the center of the connecting rod three.
[0009] Furthermore, the drill bit removal device also includes a crowbar inserted into the circular hole of the connecting rod three.
[0010] Furthermore, the connecting rod 1 and the connecting rod 2 are respectively located on both sides of the connecting rod 3.
[0011] The beneficial effects of the utility model are as follows:
[0012] The utility model inserts a crowbar into the circular hole of the third training rod and utilizes the principle of leverage to twist the third connecting rod, so that the vertical force is converted into a torsional force, which acts on the drill bit and realizes unloading of the drill bit.
[0013] The utility model has a simple structure and is easy to operate. By utilizing the utility model, work efficiency can be improved and manpower can be saved. BRIEF DESCRIPTION OF THE DRAWINGS
