Abstract
The utility model discloses a kind of coal winning machine cutting bits, including alloy head, cutting pick head and cutting pick handle, the alloy head is cone, thereafter end is fixed in cutting pick head, the rear end of the cutting pick head is equipped with the round platform with its one, round platform is fixedly connected with the cutting pick handle, and cutting pick head described in ring is circumferential to be equidistantly equipped with multiple identical pick platforms.The purpose of this utility model, which is to provide one kind, not influencing pick rotation, improves the pick of pick service life.
Description
Technical field
It is adopted the utility model is related to coal and tunnelling technical field, and in particular to a kind of coal winning machine cutting bit.
Background technology
Coalcutter is the mechanical equipment that coal mine is often used, and is cut to the rock stratum of coal mine by the pick on coalcutter,
To complete the excavation of coal mine, since the working condition of mining pick is more severe, it is easy for tooth head occur in use quickly grinding
Damage, is one of the vulnerable part in coal mining and tunnelling machinery, performance quality directly affects the production capacity of coal-cutting machinery.
The tooth head of pick is divided into non-rotatable and two kinds rotatable, wherein rotatable often because of cutting pick head design
Problem causes wherein its rotation angle small, leads to alloy head eccentric wear problem.Pick header structure is changed in the prior art
Into improving rotational resistance, ensure that its rotation angle.Although but above-mentioned technical proposal reduces rotation resistance to a certain extent
Power, but do not reach better rotates effe.
Utility model content
Therefore, the purpose of this utility model, which is to provide one kind, not influencing pick rotation, improves the pick of pick service life.
A kind of coal winning machine cutting bit of the utility model, including alloy head, cutting pick head and cutting pick handle, the alloy head are circular cone
Body, thereafter end be fixed in cutting pick head, the rear end of the cutting pick head is equipped with the round platform with its one, round platform and the pick
Handle is fixedly connected, and cutting pick head described in ring is circumferential to be equidistantly equipped with multiple identical pick platforms.
Optionally, the mid diameter in each section of the pick platform in axial direction is big, and both sides diameter of section successively decreases.
Optionally, the distance between described pick platform is 1mm-1.8mm.
Optionally, the peripheral level of the pick platform is equal with the round platform diameter.
Optionally, alloy head KE9 materials.
Technical solutions of the utility model have the following advantages that：
Coal winning machine cutting bit provided by the utility model, including alloy head, cutting pick head and cutting pick handle, the alloy head are circular cone
Body, thereafter end be fixed in cutting pick head, the rear end of the cutting pick head is equipped with the round platform with its one, round platform and the pick
Handle is fixedly connected, and cutting pick head described in ring is circumferential to be equidistantly equipped with multiple identical pick platforms, because pick platform is to be arranged in flat week,
Its rotation angle is not influenced during rotation so that the axle center of rotation is stablized, and axle center deflection will not occur, avoid alloy head
Eccentric wear problem, extend cutting-gear life.
Description of the drawings
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art

Novel protected range.
It is in the description of the present invention, it should be noted that term "center", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
The utility model and simplifying describes for ease of description, do not indicate or imply the indicated device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, can also be electrical connection；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, it can understand above-mentioned art with concrete condition
The concrete meaning of language in the present invention.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
Embodiment 1
A kind of coal winning machine cutting bit provided in this embodiment, it is shown in Figure 1, including alloy head 1, cutting pick head 2 and cutting pick handle
3, alloy head 1 is cone, and end is fixed in cutting pick head 2 thereafter, and the rear end of cutting pick head 2 is equipped with the round platform 3 with its one,
Round platform 3 is fixedly connected with cutting pick handle 4, and ring cutting pick head 2 is circumferential to be equidistantly equipped with multiple identical pick platforms 21, each pick platform 21
The distance between be 1mm-1.8mm, generally 1mm；The peripheral level of pick platform 21 is equal with 3 diameter of round platform.
Specifically, the mid diameter in the section of each pick platform 21 in axial direction is big, and both sides diameter of section successively decreases, axial
Section is shown in Figure 2.
In order to improve hardness, alloy head 1 uses KE9 materials.
During driving, the alloy head distance of the extended length 30mm of coal winning machine cutting bit, the pick after installation are scraped
Mud plate motor spindle decreases, therefore, it is possible to reduce when cross gathering coal, have preferable crushing effect.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
Among the protection domain that variation is created still in the utility model.
