The upper end of the shaft 10 is connected with the turntable 12 through the support bearing 11, the drive shaft 30 coaxial with the support shaft 10 is vertically arranged on the turntable 12, the driven gear 31 is fixedly set on the drive shaft 30, and the upper end of the support plate 9 is common Fixedly connected with top plate 27, rotary drive motor 28 is fixedly arranged on the top plate 27, and the output shaft of rotary drive motor 28 passes through top plate 27 and is driven to be connected with drive gear 29, and drive gear 29 and driven gear 31 are meshed.

During use, utilize rotary drive motor 28 to drive driving gear 29 to rotate, because driving gear 29 and driven gear 31 are mutually meshed, so driving gear 29 can drive driven gear 31 to rotate, and then utilize driven gear 31 to drive drive shaft 30 Rotate, the drive shaft 30 drives the turntable 12 to rotate during the rotation process, and then drives the bearing frame 18 and the material separation net 23 to rotate through the rotation rod 16, so as to realize the alternate use of multiple material separation nets 23, and then realize the unloading without interrupting the material transportation Effect.

On the other hand, because the rotary drive motor 28 is fixedly arranged on the top plate 27, and the cooperation of the driving gear 29 and the driven gear 31 drives the turntable 12 to rotate, so the rotary drive motor 28 does not need to directly bear the load brought by the gravity of the turntable 12, The rotary drive motor 28 can be effectively protected.

A part of the rotating rod 16 can extend into the mounting hole 13 to improve the bearing capacity of the rotating rod 16.

As shown in Figure 3, in order to facilitate the adjustment of the rotating rod 16 to drive the bearing frame 18 and the material separation net 23 to rotate to realize unloading, the turntable 12 is fixedly provided with an overturning drive motor 26, and the output shaft of the overturning drive motor 26 is horizontally arranged and driven. A driving pulley 25 is arranged, and a driven pulley 17 is fixedly sleeved on the rotating rod 16, and a driving belt 24 is connected between the driving pulley 25 and the driven pulley 17.

After the material separation net 23 is fully loaded with material and rotates to the side of the front end water tank 6, the driving pulley 25 is driven by the turning drive motor 26 to rotate, and then the driving pulley 25 drives the driven pulley 17 to rotate through the transmission belt 24, from Driving pulley 17 drives rotation bar 16 to rotate in the course of rotation, can realize unloading.

Because the material will accumulate in a conical shape when it falls onto the material separation net 23, causing the load in the middle of the material separation net 23 to be higher than the edge, thereby reducing the load-carrying capacity of the material separation net 23. capacity, in order to reduce the unloading frequency, each of the two oppositely arranged edges of the bearing frame 18 is provided with a vertically extending through groove, and a floating plate 20 is arranged up and down in the through groove, and the bottom of the floating plate 20 extends out of the through groove and is fixed.

When the material falls into the material separation net 23, by pushing the lifting plate 19 to move up and down, it drives the connecting plate 21 and the suspension plate 22 to move up and down synchronously, and then drives the material separation net 23 to shake up and down, so as to ensure that the material can be evenly distributed. Spread on the material separation net 23 to make the load of each part of the material separation net 23 even, and realize the effect of improving the load capacity of the material separation net 23 .

Because the material separation net 23 is positioned at the top of the front end water tank 6 when the material enters the material separation net 23, in order to facilitate the lifting plate 19 to move up and down, the top of the front end water tank 6 is provided with at least one pushing mechanism, when the material separation net 23 rotates to When between the end of conveying pipe 3 and front end water tank 6, pushing mechanism promotes lifting plate 19 to move up and down.

When the small-diameter end of the eccentric wheel is in direct contact with the vibrating plate 34, the push rod 38 descends and resets. When the major diameter of the eccentric wheel was in direct contact with the vibrating plate 34, the push rod 38 would move up. When the material enters the material separation net 23, the motor 37 is started, and the push rod 38 is driven up and down repeatedly by the drive of the eccentric wheel, and then the material separation net 23 is vibrated.

In order to avoid damage to one of the parts caused by the frequent collision between the push rod 38 and the lifting plate 19, the upper end of the push rod 38 is fixedly connected with a contact 39, and the contact 39 can be made of a material with buffer capacity such as rubber, so as to realize the alignment between the push rod 38 and the lifting plate 19. The protection of lifting plate 19.

Because the water itself will be polluted by the material during the movement of the mixed material, resulting in a lot of impurities in the water, in order to avoid the rapid decrease of fluidity and conveying capacity caused by the increasing number of impurities in the recycled water, the front water tank 6 is detachable. Filter mechanism 33 is arranged.

As shown in Figure 4, the filter mechanism 33 includes a plurality of filter frames 40, the inner wall of the front end water tank 6 is provided with a pallet 32 for supporting the filter frame 40, the inside of the filter frame 40 is fixedly provided with a filter screen 41, the edge of the filter frame 40 A hoisting block 42 is fixedly connected, and a hoisting hole 43 is provided on the hoisting block 42 .

Through the filter mechanism 33 , the water separated by the material separation net 23 can be filtered to reduce the impurity content therein, and the filtered water is sent back to the rear water tank 2 through the return pipe 7 .

In addition, because the filter screen 40 will be blocked due to the adsorption of impurities after a period of time, it needs to be removed for cleaning or replacement. By setting multiple filter screens 41, the total weight of a single filter screen 41 after clogging can be reduced, and a lifting block 42 is provided. , the effect of dismantling the filter screen 41 can be quickly realized by hoisting, and the efficiency can be improved.

It should also be noted that even after being filtered by the filter mechanism 33, impurities cannot be completely removed, which leads to the need to replace new clean water after long-term use, but because the waste water has been recycled for many times, it can still be saved. Effects on water resources.

In order to improve the stability of the filter frame 40 and the filter screen 41, avoiding it from shaking under the impact of the water flow to cause deviation, the filter frame 40 is set as a rectangular frame, and the hoisting blocks 42 are fixedly arranged on two short sides of the filter frame 40, and the filter frame Several permanent magnets 44 for attracting other filter frames 40 are embedded in the long sides of the filter frame 40 . Adjacent filter frames 40 can be attracted together by using permanent magnet 44 to achieve the effect of avoiding shaking. Correspondingly, the filter frame 40 should be made of a material that can be attracted by the permanent magnet 44 , which belongs to the prior art and will not be repeated here.
