Description
Technical field
The utility model belongs to tooth set technical field, and in particular to a kind of Novel toothed set for coalcutter.
Background technique
Pick on coal mining machine in full-mechanized mining face roller is broken the main tool of coal, broken coal, coal breakage, while being also coalcutter
It is easiest to one of the accessory of loss, is easy to appear and gets rid of tooth set phenomenon, each roller of sometimes one original class can occur getting rid of tooth set 3-5
It is a, it is the discovery that caused by coalcutter toothholder serious wear through in-site measurement.Original uses on BR74 tooth set standard component outer diameter
57.28mm, 50.80mm under outer diameter, tooth cap bag to snap ring 101mm, between cannot avoiding its part well friction causing for a long time
Gap is excessive so as to cause part shaking.
Therefore, those skilled in the art provide a kind of Novel toothed set for coalcutter, to solve above-mentioned background technique
The problem of middle proposition.
Utility model content
The purpose of this utility model is to provide a kind of Novel toothed sets for coalcutter, can establish and comprehensively consider earth material
The erosion model of each physicochemical characteristics obtains the equipment in fields such as water conservancy and hydropower, disaster reduction and prevention more extensive
Application.
The technical scheme adopted by the utility model is a kind of Novel toothed set for coalcutter, including tooth cover the first structure
Part, tooth set second component and tooth cap bag, the tooth set second component are welded in tooth set first component upper end, the tooth cap bag welding
First component lower end is covered in tooth, tooth set first component two sides are welded with connecting block, and described connecting block one end is welded with card
Fishplate bar.
The utility model is also characterized by being passed through inside the tooth set first component, tooth set second component and tooth cap bag
It wears and opens up hole, the tooth set second component offers annular groove close to hole interior lower end.
The utility model is also characterized by tooth set second component lower end is welded with jump-ring slot, under the jump-ring slot
End is welded with fixed ring.
The utility model is also characterized by the tooth set first component length is 57.88mm, the tooth covers second component
Length is 51.50mm, and the jump-ring slot to tooth cap bag bottom lengths is 99mm.
The utility model is also characterized by the clamping plate shape is arc.
The beneficial effects of the utility model are:
There are connecting block and card adapter plate by design, its tooth set first component is passed through into card adapter plate and connecting block set access toothholder
In, card adapter plate will be engaged with the groove in toothholder, and it is 57.88mm that tooth, which covers first component length, and it is long that tooth covers second component
Degree is 51.50mm, and jump-ring slot to tooth cap bag bottom lengths is 99mm, so that it is even closer to cooperate it with toothholder, is effectively solved
Tooth set phenomenon is got rid of, tooth set cooperates optimum efficiency with toothholder.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the plan view of the utility model；
Fig. 3 is the sectional view of the utility model.
In figure, 1- tooth covers first component, 101- tooth covers second component, 2- tooth cap bag, 3- connecting block, 4- card adapter plate, the hole 5-
Hole, 6- annular groove, 7- jump-ring slot, 8- fixed ring.
Specific embodiment
With reference to the accompanying drawing and the utility model is described in detail in specific embodiment.
The utility model provides a kind of Novel toothed set for coalcutter, as shown in Figure 1-3, it is a kind of for coalcutter
Novel toothed set, including tooth set first component 1, tooth set second component 101 and tooth cap bag 2, which is characterized in that the tooth covers the second structure
Part 101 is welded in tooth set 1 upper end of first component, and the tooth cap bag 2 is welded in tooth set 1 lower end of first component, the tooth set first
1 two sides of component are welded with connecting block 3, and described 3 one end of connecting block is welded with card adapter plate 4.
Run through inside the tooth set first component 1, tooth set second component 101 and tooth cap bag 2 and opens up hole 5, it is described
Tooth covers second component 101 and offers annular groove 6 close to 5 interior lower end of hole.
The tooth set 101 lower end of second component is welded with jump-ring slot 7, and 7 lower end of jump-ring slot is welded with fixed ring 8.
Tooth set 1 length of first component is 57.88mm, and tooth set 101 length of second component is 51.50mm, described
It is 99mm that jump-ring slot 7, which arrives 2 bottom lengths of tooth cap bag,.
4 shape of card adapter plate is arc.
Staff can fill in its pick from the hole 5 in tooth cap bag 2, thus firmly press its pick,
Ring spring in pick will be clamped in annular groove 6, and so as to which its pick is fixed, its tooth is then covered first again
Component 1 is by the way that in 3 sets of access toothholders of card adapter plate 4 and connecting block, card adapter plate 4 will be engaged with the groove in toothholder, thereafter
It will be clamped in its jump-ring slot 7 into circlip again, its toothholder is finally welded into the rotation of coalcutter by the achievable fixation with toothholder again
In wheel, to complete sequence of operations.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
