Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model provides a stirrer with an anti-blocking function for a concrete mixing plant, which mainly comprises a tank body 1, wherein the lower side of the tank body 1 is of a tapered cone hopper structure, the bottom end of the tank body 1 is provided with a discharge port 2, and the tank body 1 is arranged on the ground or other platforms through supporting legs 3. The vertical (mixing) shaft 4 that is equipped with in jar body 1, it has a plurality of groups stirring vane 6 to distribute in proper order from top to bottom on the (mixing) shaft 4, and the downside of (mixing) shaft 4 stretches into row material mouthful 2 to be equipped with auger blade 7 in the part that lies in row material mouthful 2. The top end of the stirring shaft 4 penetrates through the top of the tank discharging body 1 and is connected with a driving motor 5 in a transmission way. Can drive (mixing) shaft 4 and auger blade 7 through driving motor 5 and stir the material in jar body 1 and bin outlet 2, and auger blade 7 can produce the effect of stirring and upwards billowing to the material, prevents to be located the material of jar body 1 lower part and deposits and condense.

Turbulent plates 13 are arranged on the upper side and the lower side of the stirring blade 6 at intervals, and the turbulent plates 13 on the same stirring blade 6 are arranged in a vertically staggered manner, so that materials can be better stirred and mixed.

A moving plate 8 is further arranged above the tank body 1, the bottom of the driving motor 5 is fixed on the moving plate 8, and the stirring shaft 4 penetrates through the moving plate 8 and is rotatably connected with the moving plate 8. The bottom fixedly connected with of movable plate 8 has a plurality of synchronous telescopic cylinder 9, and the fixed top of locating jar body 1 in the bottom of telescopic cylinder 9, and telescopic cylinder 9's telescopic link top and the bottom fixed connection of movable plate 8 can drive movable plate 8 and then drive driving motor 5 and (mixing) shaft 4 through telescopic cylinder 9 and carry out the up-and-down motion.

The number of the telescopic cylinders 9 is not particularly limited, but in the present invention, in order to facilitate the driving of the driving motor 5 and the stirring shaft 4 to move better, the number of the telescopic cylinders 9 is 2, and the telescopic cylinders are symmetrically distributed on the left and right sides of the stirring shaft 4.

A circular push plate 10 is arranged at the lower end of the stirring shaft 4, a scraping piece 11 is arranged on the peripheral side of the push plate 10, and the thickness of the scraping piece 11 is consistent with that of the push plate 10. The blade 11 is preferably made of rubber, and the circumferential side of the blade 11 is attached to the inner wall of the discharge opening 2. Push pedal 10 cooperation doctor-bar 11 seals bin outlet 2, need not additionally to install the valve, and doctor-bar 11 when (mixing) shaft 4 drives push pedal 10 up-and-down motion, can scrape the clearance to the inner wall of bin outlet 2. The distance between the turbulence plate 13 at the uppermost side and the inner top wall of the tank body 1 is greater than the maximum distance which can be moved by the push plate 10, so that the turbulence plate 13 is prevented from colliding with the tank body 1 when the push plate 10 moves upwards.

In order to better seal the discharge opening 2, the bottom end of the discharge opening 2 is concavely provided with a circular ring-shaped limiting boss 12, so that materials can be discharged from an annular cavity on the inner side of the limiting boss 12. The diameter of the push plate 10 is larger than the inner diameter of the limit boss 12. The push plate 10 comprises two states of abutting against the top of the limiting boss 12 and being positioned above the discharge port 2.

When the telescopic rod of the telescopic cylinder 9 is in a non-extension state, the bottom of the push plate 10 and the scraper 11 can abut against the top of the limiting boss 12, and the state shown in fig. 2 is presented. Because the diameter of push pedal 10 is greater than the internal diameter of spacing boss 12, therefore even push pedal 10 rotates along with (mixing) shaft 4 constantly, still can keep the relative sealed state of bin outlet 2, and doctor-bar 11 can play better sealed effect with the laminating of the inner wall of bin outlet 2 mutually. In addition, the existence of the limiting boss 12 avoids the phenomenon that the scraping blade 11 is bent downwards due to the gravity of the material to cause material leakage.

When the telescopic rod of telescopic cylinder 9 extends and drives push plate 10 to move to the top of discharge gate 2, discharge gate 2 is in the open state, presents the state as shown in fig. 3, and the material can be discharged smoothly.

When the blanking in the discharge opening 2 is not smooth, the stirring shaft 4 is controlled by the telescopic cylinder 9 to drive the push plate 10 to move downwards, so that the material in the discharge opening 2 can be extruded out in time. Meanwhile, the scraping blade 11 can scrape off materials attached to the inner wall of the discharge opening 2, so that smooth and thorough blanking is ensured.

When in actual use, the telescopic cylinder 9 can reciprocate to drive the push plate 10 to move up and down continuously, so as to apply external force to the material continuously and help the material to be discharged smoothly.

The working principle is as follows: according to the mixer with the anti-blocking function for the concrete mixing station, when materials are mixed, the telescopic cylinder 9 is controlled to move the push plate 10 into the discharge opening 2 and attach the push plate to the limiting boss 12, so that the discharge opening 2 is in a sealed state; when discharging, the telescopic cylinder 9 drives the push plate 10 to move to the upper part of the discharge port, so that the material can flow out from the gap between the push plate 10 and the discharge port 2 and is discharged out of the tank body 1; if the blanking in the discharge opening 2 is not smooth, the push plate 10 is controlled by the telescopic cylinder 9 to return to the discharge opening 2 again to press out the blocked materials in the discharge opening 2, and the push plate 10 is controlled to ascend to the upper side of the discharge opening 2 to continue discharging after the cleaning is finished.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
