Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of coal plough of the utility model with the planer head preferred embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, Fig. 1 is the structural representation of the utility model coal plough with planer head embodiment.
The present embodiment coal plough with planer head comprise movable carriage 6 and the activity that is connected with movable carriage 6 heighten the seat 5, also comprise the knife rest position adjusting mechanism; The knife rest position adjusting mechanism comprises hydraulic cylinder 1; And to heighten seat 5 hinged with the plane body of coal plough with activity respectively for hydraulic cylinder 1.Certainly, hinged is wherein a kind of connected mode, and hydraulic cylinder 1 also can adopt hinged other outer connected modes.
In the present embodiment, heighten seat 5 through the up-down drive activity of hydraulic cylinder 1 and move up and down along the planer head vertical track, and realize the purpose that planer head is heightened with this with movable carriage 6.
With respect to prior art, present embodiment has following advantage:
The first, the utility model utilizes hydraulic cylinder drive activity to heighten seat, realizes stepless heighten of coal plough planer head in grade section is arranged, and in time adapts to the localized variation of coal seam thickness, improves production efficiency
The second, adopt hydraulicdriven mode to realize heightening of planer head, compact conformation, stable drive.
Three, to heighten mode different with the machinery of worm-and-wheel gear, and the mode of the heightening clean and effective based on hydraulic cylinder has reduced fret wear and energy consumption.
In addition, need to prove, though in the present embodiment, the knife rest position adjusting mechanism includes only a hydraulic cylinder; But, during actual enforcement, can be according to the hydraulic cylinder of the different choice suitable quantity of operating mode, for example, single hydraulic cylinder can be replaced by two little cylinder diameter hydraulic cylinders, and two small cylinders can be arranged in juxtaposition in casing.
In the technique scheme, also be provided with reversible lock on the hydraulic cylinder 1, the effect of this reversible lock is that movable carriage 6 is locked at suitable height.
In addition, hydraulic cylinder can pass through high-pressure emulsion pumping plant feed flow, and small pumping station perhaps is installed at coal plough bracing frame place, and this small pumping station is directly controlled by central control room.That is to say that directly control is perhaps by the switch control that is arranged on face end by central control room in the up-down of hydraulic cylinder, such design can be under non-stop-machine state, and stepless the heightening of realization activity planer head improved operating efficiency.Certainly, the control of hydraulic cylinder also can be by the switch control that is arranged on face end.
With reference to Fig. 1, as can be seen from Figure 1, this preferred embodiment comprises that also three are increased piece once more: first increases piece 2, second increases piece 3 and the 3rd and increases piece 4.Concrete annexation is, hydraulic cylinder 1 passes first respectively to be increased piece 2, second and increase piece 3 and the 3rd and increase piece 4, and heightens on the seat 5 with the hinged mode activity of being fixed on.The effect of increasing piece here, also is an adjustment planer head height.The number of increasing piece through adjustment realizes the adjustment of planer head height.Need to prove that the utility model does not limit the quantity of increasing piece,, have choosing of needing to get final product according to the thickness in actual coal seam.
Remark additionally, increase piece and hydraulic cylinder 1 can be realized the adjustment to movable carriage vertical direction height.General situation is according to the thickness in coal seam, to confirm to increase the quantity of piece; Be used to realize " coarse adjustment " of planer head height, realizing that the planer head height generally still can not satisfy the needs of precision after " coarse adjustment "; At this moment; Need to pass through the flexible of hydraulic cylinder, the adjustment of realization activity cutter head position, this process can be called " accurate adjustment ".
In the reality, when very thin as if coal seam thickness, the situation of piece can occur need not increasing, therefore, increasing piece is not to be indispensable, accept or reject to some extent according to operating mode yet.
Second aspect, the utility model also provide a kind of coal plough, comprise the planer head that is connected and dig body, and said planer head is that above-mentioned any coal plough is used planer head.Because the structure of planer head has been done detailed explanation in the above-described embodiments, the present invention repeats no more at this, and relevant part cross-reference gets final product.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
