Pass through above-mentioned technical proposal, sieve plate one and sieve plate two can screen to the concrete block fallen, concrete block Block footpath be more than sieve aperture one can not by sieve plate one, block footpath be less than sieve aperture one continued by sieve plate one drop down onto sieve plate two. The side of sieve plate two impacts to concrete block, while the inwall of sieve aperture two of sieve plate two can collide to concrete block, make it It is broken, when avoiding the concrete block from falling on agitator tank, larger impulsive force is produced to it.

The utility model is further arranged to：Also include the actuator for driving the sieve plate two to slide.

Pass through above-mentioned technical proposal, actuator can drive sieve plate two, achieve automatic back-and-forth motion.

The utility model is further arranged to：The sieve plate one is fixedly arranged above charging aperture.

Pass through above-mentioned technical proposal, feed hopper can be collected screening from the concrete block that conveying device is fallen to sieve plate one Gear, makes concrete block be unlikely to tumble from sieve plate one.

The utility model is further arranged to：The inwall both sides of sieve plate one are all provided with fluted, and the both sides of sieve plate two are equal Provided with projection, the projection is slidably connected with the groove.

Pass through above-mentioned technical proposal, projection are slidably connected with groove, reduce rubbing for the inwall of sieve plate one and sieve plate two side faces Contact is wiped, reduces frictional force, accelerates sliding speed.

The utility model is further arranged to：The sieve aperture two of the sieve plate two is identical with the size of sieve aperture one.

Pass through above-mentioned technical proposal, sieve aperture one are identical with sieve aperture two so that in sliding process, concrete block can be more Fast is dropped from sieve plate one and sieve plate two, and concrete block will not be caused to be stuck in sieve aperture and block sieve aperture.

The utility model is further arranged to：The actuator is cylinder.

Pass through above-mentioned technical proposal, for cylinder for other devices, price is relatively low, more economical.

In summary, the utility model has the advantages that：

1st, sieve plate one can screen to the concrete block fallen from conveying device；

2nd, sieve plate two is driven by cylinder, can be impacted to falling on the concrete block in the cavity of sieve plate one, to falling on sieve In hole two collide；

3rd, feed hopper is collected to the concrete block that conveying device is fallen so that concrete block falls on sieve plate as far as possible One.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment：A kind of feed mechanism of concrete drums, as shown in figure 1, feed mechanism includes agitator tank 1, conveying Device 2 and sorting mechanism 3.Sorting mechanism 3 is located at the lower end of conveying device 2, the upper end of agitator tank 1.

As shown in Fig. 2 sorting mechanism 3 includes support 31, sieve plate 1, sieve plate 2 33 and feed hopper 35.Support 31 is fixed In the lower end of the discharging opening of conveying device 2, agitator tank 1 is fixed on the lower section of support 31, sieve plate 1 be fixed on support 31 and The tank mouth 11 of agitator tank 1 below face, the upper end of sieve plate 1 are fixed with feed hopper 35, and the inside of sieve plate 1 is hollow form and side Provided with opening.The upper and lower surface of sieve plate 1 is distributed with some sieve apertures 1.

As shown in Figures 2 and 3, sieve plate 2 33 is slidably connected in the cavity of sieve plate 1, the both sides inwall of sieve plate 1 is equal Fluted 36 are opened up, the both sides of sieve plate 2 33 are respectively and fixedly provided with projection 37, and projection 37 is slidably connected with groove 36.Sieve plate 2 33 is remote The side of cavity is fixedly connected with cylinder 34, and cylinder 34 is fixed on support 31, for driving sieve plate 2 33 to be slided in cavity.

As shown in Figure 2 and Figure 4, sieve plate 2 33 is provided with the vertical sieve aperture 2 331 for running through sieve plate 2 33, sieve aperture 2 331 with The shape size of sieve aperture 1 is identical, when in the fully-inserted sieve plate 1 of sieve plate 2 33, sieve aperture 2 331 and sieve aperture 1 Correspond, facilitate concrete to pass through.

The course of work：The conveyer belt 21 of conveying device 2 transports concrete block to sorting mechanism 3 first, and cylinder 34 is back and forth Sieve plate 2 33 is promoted, the projection 37 of sieve plate 2 33 cooperates with the groove 36 of sieve plate 1 so that sieve plate 2 33 is in sieve plate one Slidably reciprocated in 32.

Concrete block leaves conveyer belt 21 and dropped downwards, and the sieve aperture one of the upper surface of sieve plate 1 is fallen on by feed hopper 35 After 321, the concrete block bigger than sieve aperture 1 does not enter sieve aperture 1, is not selected；The continuation smaller than sieve aperture 1 is downward Drop；A part is fallen in the cavity of sieve plate 1, because sieve plate 2 33 moves back and forth, one side meeting of the sieve plate 2 33 away from cylinder 34 Concrete block is impacted；Another part is fallen in the sieve aperture 2 331 of sieve plate 2 33, and the inwall of sieve aperture 2 331 also can be to coagulation Soil block, which produces shock, makes it broken；Then concrete block continues to drop downwards, by the sieve aperture 1 of the bottom surface of sieve plate 1, most After drop down onto in agitator tank 1.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
