Example 1:

a lifting and dumping mechanism for industrial residues is used for lifting combustible industrial residues such as sawdust, wood board leftover materials and the like and dumping the combustible industrial residues into a storage box 2 which is placed in the air. As shown in fig. 1, the lift-and-dump mechanism includes a lift frame, a storage tank 2, a lifting hopper 3, and a hoist 4, which will be described in detail below.

As shown in fig. 2, the lifting frame has four landing legs, two of which are formed by a pair of groove-shaped guide rails 1, and the notches of the pair of groove-shaped guide rails 1 are arranged oppositely. Every cell type guide rail 1 comprises promotion section 11, circular arc changeover portion 12 and slope section 13, and promotion section 11 and slope section 13 are the straightway, and circular arc changeover portion 12 sets up between promotion section 11 and slope section 13, and the contained angle of slope section 13 and level line is 12. In order to reduce the manufacturing cost, the groove-shaped guide rail 1 can be directly formed by bending channel steel.

The storage box 2 is a square box body with a groove-shaped notch, wherein one surface at the lower part of the groove-shaped notch is parallel to the guide surface of the inclined section 13 of the groove-shaped guide rail 1. In order to prevent rainwater from entering the box, the square box body is provided with a top surface. Storage box 2 is fixed on the hoisting frame, and its lower part is unsettled, and such design is firstly for conveniently unloading to the transport truck, reduces the loading and unloading expense, and secondly for keeping apart the naked light, and thirdly for reducing the occupation to ground space.

As shown in fig. 3, the casing of the hopper 3 has a shape corresponding to the shape of the notch of the storage box 2, and includes a bottom plate 33 and two opposite side plates 34. A flap 31 with a rotary shaft 32 is mounted between the two side plates 34, the flap 31 being arranged eccentrically with respect to the rotary shaft 32. Two pairs of guide wheels 39 are arranged on the outer side of the two side plates 34, the guide wheels 39 comprise wheel shafts and bearings, and for the purpose of simplifying the structure, the bearings roll along the groove-shaped guide rail 1 as rolling bodies, and the guide wheels 39 and the groove-shaped guide rail 1 limit the remaining degrees of freedom of the elevator bucket.

In order to form a bucket structure for carrying sawdust, a front baffle 36 and a vertical plate 35 are also arranged on the bottom plate 33. When the sawdust is lifted, the lifting hopper 3 is in a state as shown in fig. 3, and at this time, under the action of an eccentric force, the longer side of the turning plate 31 is overlapped with the vertical plate 35 to form a rear baffle, and the bottom plate 33, the two side plates 34, the front baffle 36 and the rear baffle form a hopper structure. At this time, the turning plate 31 is not turned over by the saw dust and the vertical plate 35. In order to ensure the stability of the sawdust lifting, the lifting section 11 forms an angle of 5 ° with the vertical line, so that the material lifting bucket 3 is slightly inclined, and the sawdust is prevented from falling out of the material lifting bucket 3.

As shown in fig. 4, a hoist 4 is provided on the top of the storage tank 2 for lifting the lifting hopper 3. The hoisting machine 4 includes a motor, a speed reducer, and a hoisting shaft with a reel.

A trigger piece is fixed on the storage box 2, and the trigger piece is a collision block 21. When the sawdust is lifted, the winch 4 is started, and the material lifting hopper 3 moves upwards under the dragging of the steel wire rope 41; when the guide wheel 39 enters the arc transition section 12 of the groove-shaped guide rail 1, the material lifting hopper 3 inclines towards the groove-shaped gap of the storage box 2; when the two pairs of guide wheels 39 completely enter the inclined section 13 of the groove-shaped guide rail 1, the lifting hopper 3 is completely dumped at the groove-shaped gap of the storage box 2, at the moment, the connecting lever 37 is contacted with the collision block 21, and the turning plate 31 is driven to turn over towards the inner side of the storage box 2, so that automatic unloading is realized. At the same time, the elevator bucket is in full contact with the groove-shaped indentations of the storage box 2 and forms a complete box structure with the storage box 2. When the materials are lifted again, the winch 4 rotates reversely, the guide wheel 39 of the elevator bucket slides downwards along the inclined section 13 of the groove-shaped guide rail 1 under the action of the gravity of the elevator bucket, the crank arm 37 is separated from the contact with the collision block 21, and the turnover plate 31 is overlapped with the vertical plate 35 again under the action of the eccentric force to form a cargo bucket structure. In order to prevent the turning plate 31 from being turned over excessively, the structure of the rear baffle plate for blocking the material cannot be reconstructed with the vertical plate 35, and the turning angle of the turning plate 31 is not more than 80 degrees. In another practical scheme, a torsion spring can be installed at the rotating shaft 32, and when the elevator bucket lifts materials again, the torsion spring enables the turning plate 31 to turn reversely and to be overlapped with the vertical plate 35 again to form a bucket structure.

Therefore, the lifting hopper is a lifting carrier of sawdust and is a component of the whole box structure, and the problem of difficulty in putting sawdust due to the fact that the storage box 2 is covered is solved skillfully; the elevator bucket can automatically slide downwards by depending on the slope of the inclined section 13 of the groove-shaped guide rail 1, and an additional reverse dragging structure is not required to be designed for the winch 4; the turning plate 31 is matched with the mechanism to act, so that automatic overturning and discharging are realized.

Example 2:

the technical scheme in embodiment 1 can not solve the sawdust uneven distribution problem in the storage box 2, because the angle of unloading of turning over board 31 is invariable, the sawdust can be piled up in one side of storage box 2, and the other side is in for not occupying the state, influences the storage rate.

The difference between this embodiment and embodiment 1 is that, as shown in fig. 6, the turning member is a gear 38, and the gear 38 is connected to one end of the rotating shaft 32; the triggering member is a rack 22, and the rack 22 is fixed on the storage box 2. When the gear 38 contacts the rack 22, the turning plate 31 turns over 270 degrees, sawdust is firstly poured on one side of the storage box 2, then the sawdust is turned over continuously, and the sawdust accumulated on the side is stirred and thrown towards the other side to be spread evenly. When the lifting bucket lifts materials again, the turning plate 31 is reversely turned under the driving of the rack 22, the scraped sawdust is turned up and thrown, and then the sawdusts are overlapped with the vertical plate 35 again to form a bucket structure.
