Detailed description of the invention
With reference to Figure of description, a kind of band of the present invention is smoothed out with the fingers material device chain type concrete spraying machine to be described in detail below.
As shown in Figure 1-Figure 3, material device chain type concrete spraying machine smoothed out with the fingers by a kind of band of the present invention, its structure by hopper, launch cylinder body 10 and smooth out with the fingers material device form, wherein, the bottom of hopper is connected with launching cylinder body 10 top, smoothes out with the fingers and expects that device is arranged on the right side below hopper and internals and is connected with the charging aperture 11 of transmitting cylinder body 10.
Material device chain type concrete spraying machine smoothed out with the fingers by described band, and hopper is made up of feed hopper 7 and feeding hopper 8, and wherein, feed hopper 7 is positioned at the top of feeding hopper 8, and the middle flange 9 that passes through connects.
Material device chain type concrete spraying machine smoothed out with the fingers by described band, smooth out with the fingers material device by smoothing out with the fingers flitch 1, rotating shaft 2, bearing block 3, swing connecting bar 4, drawing spring 5 and draw spring shield 6 to form, the lower right-hand side of feed hopper 7 runs through rotating shaft 2, the two ends of rotating shaft 2 are connected with the bearing block 3 being arranged on flange 9, smoothing out with the fingers flitch 1 to be arranged in the middle of rotating shaft 2, the lower end smoothing out with the fingers flitch 1 is positioned at the top launching cylinder body 10 charging aperture 11.
Material device chain type concrete spraying machine smoothed out with the fingers by described band, draw the case structure that spring shield 6 is made up of casing and case lid, case lid is bolted on the opening of casing, the bottom of casing is connected with flange 9 edge, the one end of rotating shaft 2 puts in casing, swing connecting bar 4 is connected with rotating shaft 2 end, and the both sides, inside of casing connect draws spring 5, and the lower end of swing connecting bar 4 is connected in the middle of spring 5 with drawing.
Material device chain type concrete spraying machine smoothed out with the fingers by described band, and the lower end smoothing out with the fingers flitch 1 is designed as arc-shaped, and its radian is slightly larger than the cylindrical radian of tandem piston 12.
Embodiment
The operation principle of the present invention is as follows:
nullFrom hopper injecting material,Charging aperture 11 is sent by 12 materials of tandem piston in motion,Because smoothing out with the fingers the semi arch size diameter more than tandem piston 12 of flitch 1,There is h value difference in height,The tandem piston 12 moved along feed direction promotes to be smoothed out with the fingers flitch 1 and drives rotating shaft 2 to swing,And then drive swing connecting bar to swing,Now linkage draws spring 5 to enter left and right extended state,When the left side drawing spring 5 stretches,The right-hand member drawing spring 5 then eliminates the deflection of left end,After tandem piston 12 is by smoothing out with the fingers flitch 1,The short deformation energy drawing spring that keeps left retracts to be smoothed out with the fingers flitch 1 and resets,Allow and draw spring to keep swing connecting bar static equilibrium under conditions of pulling force equalization,Now smooth out with the fingers flitch 1 to be perpendicular to launch cylinder body 10,Material is smeared over along smoothing out with the fingers flitch 1,Form complete horizontal stock column,Overcome because block sandstone projection causes elastic seal ring to produce the shearing impact of stone and cylinder body edge when entering piston cylinder mouth,Thus improve the service life of sealing ring.
The foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All any amendment, equivalent or improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
Compared to the prior art the pushing belt of the present invention smoothes out with the fingers material device chain type concrete spraying machine, has advanced design, simple in construction, and effective, seal durability is high, thus has good value for applications.
In addition to the technical characteristic described in description, it is the known technology of those skilled in the art.
