Abstract

A grab bucket mechanism for garbage incineration system is composed of a fixed frame, an oil cylinder under said fixed frame, a movable frame with two grab buckets hinged to both ends of said movable frame, a joint arm hinged to the end of each grab bucket, a fixed frame with another end hinged to said fixed frame, a drive wheel sleeved to the joint of grab bucket, a driven wheel linked to said drive wheel via drive belt, and a driven wheel with several twisting wheels on its axle and with twisting blades distributed circumferentially. The winch wheel and the transmission belt mechanism below the grab buckets on the two sides are utilized to form synchronous action of twisting of the grab buckets and rotation of the winch wheel, when the oil cylinder drives the movable frame to move to enable the grab buckets on the two sides to be closed, the driving wheel drives the driven wheel to move so as to enable the winch wheel to rotate synchronously, and then the grabbed garbage materials are continuously stirred to the upper side under the action of the winch blades which are arranged on the two sides in a staggered mode, so that the materials are prevented from being mixed with the closed surface and the sealing performance of the grab buckets on the two sides is ensured, and the possibility of leakage of the fine crushed materials is avoided.

Description

Grab bucket mechanism for waste incineration system

Technical Field

The utility model belongs to the technical field of waste incineration, and particularly relates to a grab bucket mechanism for a waste incineration system.

Background

The garbage incineration becomes an important part of the circular economy, and the process is to implement the centralized incineration operation at high temperature in a furnace, so that the volume after the incineration is greatly reduced and the post-incineration treatment is carried out. In the prior art, before a boiler is used for incinerating garbage, the garbage materials in a storage pit need to be transported to a feeding hole of the boiler in batches for throwing through a grab bucket, the garbage materials are disordered in shape, and when the grab bucket grabs the garbage materials, all clamping jaws cannot be completely closed, so that a large gap is formed between every two adjacent clamping jaws, broken pieces are easy to fall off and liquid drops are easy to leak in the transportation process, if the grab bucket approaches the upper part of other equipment, the leaked materials easily pollute related parts and personnel, and the quality of a working environment is reduced; meanwhile, the leaked materials can cause the increase of the gap of the clamping space of the grab bucket, so that the series effect of simultaneous leakage of other materials can be possibly caused, and the operation efficiency of the grab bucket is reduced. Therefore, a new technical solution is needed to overcome.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the grab bucket mechanism for the garbage incineration system, which can ensure the sealing performance of each clamping jaw when the grab bucket clamps garbage materials and improve the grabbing operation efficiency.

The utility model is implemented by the following technical scheme: a grab bucket mechanism for a garbage incineration system comprises a fixed frame, a movable frame, an oil cylinder, two grab buckets, two joint arms, two driving wheels, two transmission belts, two driven wheels and two reel wheels. The fixed frame and the movable frame are both steel structural members, the oil cylinder is fixedly arranged below the fixed frame, an output shaft of the oil cylinder is connected to the movable frame, two grab buckets are hinged to two ends of the movable frame, one joint arm is arranged at the end part of each grab bucket in a hinged mode, and the other end of each joint arm is hinged to the end part of the fixed frame; in addition, the buckling surfaces of the two grab buckets are respectively provided with a sealing gasket; the two driving wheels are sleeved at the hinged joints of the two grab buckets and the movable frame, each driving wheel is connected to one driven wheel through one driving belt, and the driven wheels are installed at the bottom ends of the grab buckets through supports; the installation shaft of each driven wheel is sleeved with one twisting wheel, and twisting sheets distributed in a circumferential array manner are arranged on the wheel body of each twisting wheel.

Furthermore, the twisting sheets of the twisting wheels on the two sides are arranged in a mutually staggered mode.

Furthermore, a hanging seat is arranged above the fixing frame.

Further, the fixing frame can be arranged below the crown block device through a lifting appliance.

The utility model has the beneficial effects that: this device utilizes hank pulley and drive belt mechanism of both sides grab bucket below, form grab bucket wrench movement and hank pulley rotatory synchronization action, when the cylinder drive adjustable shelf removes and makes both sides grab bucket closed, thereby the action wheel drives from the driving wheel motion and makes the hank pulley take place synchronous revolution, and then the rubbish material of making snatching is continuously stirred to the top under the twisted sheet effect of both sides staggered arrangement, and then prevent that the material from being mingled with in the closed surface and ensure the closure of both sides grab bucket, with this stop the possibility that the material in small, broken bits takes place to leak, the sealed supplementary of both sides can prevent the liquid drop seepage simultaneously, effectively ensured going on smoothly and with this improvement work efficiency of rubbish material snatching the operation, better practicality has.

In the figure: the device comprises a fixed frame 1, a hanging seat 1a, a movable frame 2, an oil cylinder 3, a grab bucket 4, a joint arm 5, a driving wheel 6, a driving belt 7, a driven wheel 8, a reel 9 and a twisting sheet 9 a.

Detailed Description

The utility model is described in further detail below with reference to the drawings.

As shown in fig. 1, a grab bucket 4 mechanism for a waste incineration system comprises a fixed frame 1, a movable frame 2, an oil cylinder 3, two grab buckets 4, two articulated arms 5, two driving wheels 6, two transmission belts 7, two driven wheels 8 and two reel wheels 9. The fixed frame 1 and the movable frame 2 are both steel structural members, a hanging seat 1a is arranged above the fixed frame 1, the oil cylinder 3 is fixedly arranged below the fixed frame 1, an output shaft of the oil cylinder 3 is connected to the movable frame 2, two grab buckets 4 are hinged to two ends of the movable frame 2, one joint arm 5 is arranged at the end part of each grab bucket 4 in a hinged mode, and the other end of each joint arm 5 is hinged to the end part of the fixed frame 1; in addition, the buckling surfaces of the two grab buckets 4 are respectively provided with a sealing gasket; the two driving wheels 6 are sleeved at the hinged joints of the two grab buckets 4 and the movable frame 2, each driving wheel 6 is connected to one driven wheel 8 through one driving belt 7, and the driven wheels 8 are arranged at the bottom ends of the grab buckets 4 through supports; the mounting shaft of each driven wheel 8 is sleeved with one of the twisting wheels 9, twisting pieces 9a distributed in a circumferential array are arranged on the wheel body of the twisting wheel 9, and the twisting pieces 9a of the twisting wheels 9 on the two sides are arranged in a mutually staggered mode.
