In the above embodiment provided by the invention, there may be no sealing between the trigger piece 4 and the through hole on the wall plate, so that a small amount of coal may enter the through hole and even leak to the outside, which is acceptable, but preferably, a dynamic sealing structure is also provided, but the dynamic sealing is extruded or destroyed by the tiny coal, and according to this, in another embodiment of the invention, an arc-shaped rubber pad 7 is provided, a through hole is provided on the cavity wall, an arc-shaped rubber pad 7 is fixedly sealed on the opening of the through hole, preferably, if the arc-shaped rubber pad 7 is directly connected to the cavity wall to form an integral structure, a convex surface of the arc-shaped rubber pad 7 is located in the tamping cavity 2, and at this time, the inner side end of the trigger piece 4 is extruded from the cavity wall, but is isolated, so that not only is the complete sealing realized, but also the arc-shaped rubber pad of the trigger piece 4 is extruded by the tamping process of the coal cake.
In the embodiments of the present invention, the reset of the transmission assembly 5 and the trigger 4 may be accomplished by a spring 9, and the spring 9 is reset to be common knowledge, which is not described in detail. In another embodiment of the present invention, the device further includes a hemispherical block 8, the spherical surface of the hemispherical block 8 is attached to the concave surface of the tamping cavity 2, the concave surface is matched with the spherical surface, the plane of the hemispherical block 8 is connected to the steel structure frame 1 through a spring 9, the spring 9 is in a compressed state, where the spring 9 is always in a compressed state, that is, before and after the hemispherical block 8 is extruded by the arc-shaped rubber pad 7, the device is in a compressed state, the purpose is that the initial state provides a prestress in the direction of the tamping cavity 2 for the arc-shaped rubber pad 7, the pre-stress greater than that provided by the spring 9 must be provided in the process of tamping the coal cake to trigger the trigger piece 4, so as to further reduce the probability of false touch, at this time, the trigger piece 4 is movably connected to the hemispherical block 8, for example, a through hole is provided on the hemispherical block 8, one end of the trigger piece 4 is located in the through hole, or the trigger piece 4 is fixedly connected to the hemispherical block 8, or the hemispherical block 8 itself is the trigger piece 4, so that the hemispherical block 8 can be extruded by the transmission component 5 when the hemispherical block 8 reciprocates.
In the embodiments provided by the invention, the continuous feeding mechanism and the tamping mechanism 3 need to be closed in turn, namely, the continuous feeding mechanism is closed first, and the tamping mechanism 3 is closed later, because the last feeding coal needs to be tamped for a plurality of times, when the control mechanism is an automatic control system, the automatic control tamping mechanism 3 delays for a few seconds or tens of seconds, for the above-mentioned control embodiment of the complete machine, the spring 9 of the reset structure is in the initial state of the matched spring 9 of the hemispherical block 8, namely, in the compressed state, and two triggers 4 are arranged at the same time, the two triggers 4 trigger the continuous feeding mechanism and the tamping mechanism 3 on different strokes, the initial tamping pressure causes the coal cake to be not compacted, at the moment, the trigger 4 triggers a small-amplitude motion, such as 3cm, of the trigger 4 triggers the mechanical switch of the continuous feeding mechanism, then the tamping plate continuously tamps, the trigger 4 is further pressed, the trigger is in a larger amplitude motion, such as 5cm of the trigger 4 reaches the trigger, and the other trigger 4 triggers the whole tamping mechanism 3 to be closed by the pressure difference, namely, the whole tamping mechanism is closed by the pressure difference.
In the above embodiments provided by the invention, since each tamping plate moves up and down alternately, in order to prevent interference, obvious gaps are reserved between the tamping plates, so that a pressed plate 3.3 is connected to each strip groove through a rotating shaft and torsion springs, and the pressed plate 3.3 is inclined downwards in the initial position, obviously, the compressed density is definitely smaller than that of the pressed plate, but in the prior art, obvious interference is required, based on the embodiment, the tamping plate comprises a plate body 3.2, the strip grooves are respectively arranged on two opposite sides of the bottom surface of the plate body 3.2, and are only positioned at the lower half part of the plate body 3.2 in the thickness direction, and each strip groove is connected with one pressing plate 3.3 through the rotating shaft and torsion springs, so that the pressing plate 3.3 is inclined downwards in the initial position, and the pressing plate 3.2 is definitely smaller than that the pressed plate 3.3 is pressed downwards in the vertical direction, and the pressing plate 3.2 is forced to be in the same horizontal direction as the pressing plate 3.3, and the pressing plate 3.2 is forced to be in the horizontal direction when the pressing plate 3.2 is in the same, and the pressing plate 3.3 is forced to be in the horizontal direction, and the pressing plate 3.2 is in the same as the pressing plate 3.3 is pressed downwards, and the pressing plate 3.3 is forced to be in the horizontal position, and the pressing plate 3.3 is pressed downwards, and the pressing plate is in the same, and the pressing plate 3.3 is pressed down direction, and the pressing plate is pressed down, and the pressing plate 3.3 is pressed down. So on the whole, owing to the slope arrangement of stripper plate 3.3 initial position for can not have the interference between two adjacent tamping plates in the up-and-down motion process, even there is the interference in addition, stripper plate 3.3 also can rely on the swing to realize dodging and can not appear the accident, stripper plate 3.3 can be forced to expand when pressing simultaneously and increase the tamping area and make all coal cakes all can obtain the tamping, even, two adjacent stripper plates 3.3 of two adjacent tamping plates can even have the region of partial coincidence tamping, the tamping frequency in this region is twice of other regions, have many reinforcing strips in the coal cake that forms, the tamping effect is better.
More preferably, the end of the extrusion plate 3.3 far away from the plate body 3.2 is an upturned arc-shaped part, because the end of the extrusion plate 3.3 far away from the plate body 3.2 slides on the top of the coal cake in the process of moving from the initial position to the horizontal position, which may scrape the top coal bed, and the movement of the end is smoother through the arc-shaped part, so that the top coal bed cannot be scraped.
In the foregoing embodiment of the present invention, it has been described that the spring 9 at the rear side of the hemispherical shape is in a compressed state, at this time, in the process of up and down the extruding plate 3.3, the top surface of the extruding plate 3.3 presses the outer convex surface of the arc-shaped rubber pad 7, at this time, since the spring 9 gives a pressing force to the hemispherical block 8 and the arc-shaped rubber pad 7, the elastic force of the torsion spring on the rotating shaft of the extruding plate 3.3 is far smaller than the pressing force, so that the extruding plate 3.3 is forced to avoid, that is, has an avoiding position, so that the extruding plate 3.3 has three positions: the horizontal position when stamping, the incline position when stopping and the position of dodging by arc rubber pad 7 are spacing, so it can dodge arc rubber pad 7 very easily, but when extrusion plate 3.3 down touches arc rubber pad 7 from last, because extrusion plate 3.3 ascending extreme position is horizontal position, so it can inevitably mistake trigger arc rubber pad 7, based on this, this embodiment still provides a passive dodging structure, passive dodging structure is including setting up a protruding rib 11 on the cavity wall outer wall, this protruding rib 11 vertical arrangement is directly over the through hole, bottom butt joint arc rubber pad 7, can meet protruding rib 11 when extrusion plate 3.3 upward movement contact arc rubber pad 7 after it breaks away from arc rubber pad 7, so its continuous quilt is limited in this dodging position and can't resume the downward angle of slope, it still is in dodging the position when falling down once more until having broken away from arc rubber pad 7. And this structure has brought an unexpected technical effect, namely when the coal cake extruded the position of arc rubber pad 7, as mentioned above, when the extrusion plate 3.3 descends to the position of arc rubber pad 7 and is in dodging the position, but this moment the coal cake is simultaneously to the extrusion plate 3.3 a power and is forced it to rotate to the horizontal position, because the hardness of coal cake is higher and the spacing of plate body 3.2 to extrusion plate 3.3 is absolute, thereby extrusion plate 3.3 will be forced to the horizontal position and thereby the initiative extrusion arc rubber pad 7, in the aforesaid extrusion, totally rely on the extrusion of coal cake inside to trigger piece 4, trigger piece 4 just is located the position beyond the stroke of tamping plate, the coal cake does not have iron plate one and probably triggers by mistake, and at this moment, extrusion plate 3.3 all can not go to trigger arc rubber pad 7 in the daily position, only the coal cake has reached specific altitude and can be forced by extrusion arc rubber pad 7 directly, the extrusion capacity has been promoted, the probability of having reduced the false triggering, simultaneously, reduce the probability of dodging position extrusion plate 3.3 and 11 and protruding 11 can be connected at the upper and lower one and 10 in the protruding ribs, the rolling chute is provided with in order to roll in the rolling chute, the rolling chute is provided with such a 10.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
