Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal sticking removal, and in particular includes a novel coal sticking removal chisel. Background Technology
[0002] During coal conveying on a coal conveyor belt, coal tends to accumulate in the coal chute and on the T-junction baffle. To prevent blockages, this coal needs to be cleaned. Existing coal cleaning tools are welded as a single unit with a fixed rod length. This presents challenges, including difficulty in cleaning deep coal in long coal chute sections and inconvenience in narrow spaces, making them unsuitable for diverse working conditions. Furthermore, the welded rod tip cannot be replaced, failing to adapt to different coal characteristics and offering limited functionality. Additionally, the welded tip necessitates cutting and welding or complete replacement after wear, resulting in low efficiency. Therefore, there is an urgent need to design a coal cleaning tool that can effectively clean coal with varying characteristics and offers good adaptability. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of coal-sticking cleaning tool.
[0004] This new type of coal-sticking cleaning drill includes: a drill rod and a drill bit; the drill rod includes an inner rod and an outer rod, the inner rod is fitted inside the outer rod and extends out of the outer rod; the other end of the outer rod is provided with a handle; the drill bit includes a flat-head drill and a pointed drill, the end of the drill bit is provided with a drill bit sleeve, the sleeve is fitted onto the end of the inner rod.
[0005] Preferably, the side wall of the drill bit sleeve is provided with a first ball head hole, and a ball head plunger is installed on the side wall of the rod head of the inner rod. The ball head plunger includes a ball head and a sleeve. The ball head is slidably connected to the sleeve by a spring. The top of the ball head extends out of the outer wall of the drill bit sleeve, and the diameter of the ball head matches the diameter of the first ball head hole.
[0006] Preferably, the outer rod sidewall is provided with several second ball head holes of the same diameter, and the inner rod tail sidewall is equipped with a ball head plunger, the top of the ball head protruding from the outer rod sidewall, and the diameter of the ball head matching the diameter of the first ball head hole.
[0007] Preferably, rubber sleeves are fitted at both ends of the handle.
[0008] Preferably, the grip is welded to the end of the outer rod; the grip has a hollow structure.
[0009] The beneficial effects of this utility model are:
[0010] 1) The structure of this utility model is simple and easy to maintain; the extension and retraction of the drill rod is realized through the sleeve design, and the length positioning of the drill rod during extension and retraction is realized through the ball plunger, realizing multi-level length adjustment, which can adapt to various working scenarios, and at the same time makes storage and transportation more convenient when not in use.
[0011] 2) This utility model achieves the ability to disassemble and replace worn drill bits through ball-head plungers, which is economical; at the same time, it also solves the problem that a single drill bit cannot efficiently handle sticky coal with different characteristics, which is functional.

[0019] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
[0020] As one embodiment, a novel coal-sticking cleaning drill bit is proposed, such as... Figure 1-6 As shown, it includes: a drill rod and a drill bit; the drill rod includes an inner rod 2 and an outer rod 3; the outer diameter of the inner rod 2 is 24 mm, the inner diameter is 20 mm, and the length is 160 cm; the outer diameter of the outer rod 3 is 30 mm, the inner diameter is 26 mm, and the length is 170 cm; the inner rod 2 is fitted inside the outer rod 3 and extends out of the outer rod 3; the other end of the outer rod 3 is provided with a handle 10; the drill bit includes a flat-headed drill bit 1 and a pointed drill bit 4; the pointed drill bit 4 is used for piercing hard, sticky coal, and the flat-headed drill bit 1 is used for shoveling soft, sticky coal; the end of the drill bit is provided with a drill bit sleeve 6, the outer diameter of the drill bit sleeve 6 is 30 mm, the inner diameter is 26 mm, and the length is 10 cm; the drill bit sleeve 6 is fitted onto the end of the inner rod 2.
[0021] like Figure 3 , 4As shown in Figure 6, the side wall of the drill bit sleeve 6 is provided with a first ball head hole 7, the diameter of the first ball head hole 7 is 0.66 cm, and the center distance from the drill bit is 3.5 cm; a ball head plunger 13 is installed on the side wall of the rod head of the inner rod 2, and the ball head plunger 13 is located at the opening 4 cm away from the rod head; the ball head plunger 13 includes a ball head and a sleeve, the diameter of the ball head is 0.66 cm, the ball head is slidably connected to the sleeve by a spring, the top of the ball head extends out of the outer wall of the drill bit sleeve 6, and the diameter of the ball head matches the diameter of the first ball head hole 7.
[0022] like Figure 5 and Figure 6 As shown, the outer rod 3 has several second ball head holes 12 with the same diameter on its side wall. A second ball head hole 12 is provided at a distance of 10 cm, 40 cm, 70 cm, 100 cm and 130 cm from the clubhead of the outer rod 3, respectively, realizing 5-level length adjustment; the diameter of the second ball head hole 12 is 0.66 cm; a ball head plunger 13 is installed on the side wall of the inner rod 2, and the ball head plunger 13 is located at an opening 2.5 cm from the clubhead; the top of the ball head extends out of the outer wall of the outer rod 3, and the diameter of the ball head matches the diameter of the first ball head hole 7.
