Abstract
A scraper conveyor relates to a material conveying device. Mainly for solving the problem that current scraper conveyor scraper chain easily drops from the sprocket and design. The automatic feeding device comprises a box body, wherein a feeding hole is formed in the top of the box body, a discharging hole is formed in the bottom of the box body, a driving chain wheel and a driven wheel are respectively installed in the box body through shafts, a motor speed reducer is installed at the front end of the box body, and a transmission chain wheel on a shaft of the driving chain wheel is connected with a chain wheel on an output shaft of the motor speed reducer through a chain; the scraper chain is arranged on the driving chain wheel and the driven wheel; the scrapers on the scraper chain wheel comprise a plurality of vertical scrapers and inclined scrapers which are vertical to the bottom of the box, and one inclined scraper is arranged at every interval of the plurality of vertical scrapers. The wheel surface of the driven wheel is a smooth surface, and the middle part of the wheel surface is provided with a circle of annular groove which is recessed towards the interior of the driven wheel; and a guide plate is fixed on the scraper chain wheel, and the guide plate of the scraper chain is arranged in the groove of the driven wheel. The advantage is that the scraper chain is prevented from falling off from the driven wheel.
Description
The technical field is as follows:
the utility model relates to a material conveying device, in particular to a scraper conveyor.
Background art:
the existing scraper conveyor has the defects that the scraper is vertical to the bottom of the box, when wet materials are conveyed, the materials are adhered to the bottom of the box, the materials cannot be scraped away by the scraper, the materials are accumulated on the bottom of the box, production is stopped, manual cleaning is needed, and production is delayed. In addition, the scraper chain is arranged on the front chain wheel and the rear chain wheel, and the chain link length has errors, so that the larger the scraper chain length is, the larger the error is, the driving chain wheel and the driven chain wheel cannot move synchronously, and the problems of chain link accumulation and falling of the scraper chain from the chain wheels are easy to occur.
The utility model content is as follows:
the utility model aims to solve the technical problem of a scraper conveyor which is not easy to fall off through a scraper chain, can clean materials stuck on the bottom of a box and ensures smooth production.
The above object is achieved by: the automatic feeding device comprises a box body, wherein a feeding hole is formed in the top of the box body, a discharging hole is formed in the bottom of the box body, a driving chain wheel and a driven wheel are respectively arranged at the front part and the rear part in the box body through shafts, a motor speed reducer is arranged at the front end of the box body, and a transmission chain wheel on a shaft of the driving chain wheel is connected with a chain wheel on an output shaft of the motor speed reducer through a chain; the scraper chain is arranged on the driving chain wheel and the driven wheel; the method is characterized in that: the scraper on the scraper chain wheel comprises a plurality of vertical scrapers which are vertical to the bottom of the box and inclined scrapers which are inclined forwards gradually from top to bottom (the movement direction of the chain is front), each vertical scraper is provided with one inclined scraper at intervals, and the inclination angle of each inclined scraper is preferably 20-30 degrees.
The wheel surface (the surface contacted with the scraper chain) of the driven wheel is a smooth surface, and the middle part of the wheel surface is provided with a circle of annular groove which is recessed towards the interior of the driven wheel; the guide plate is fixed on the scraper chain wheel, and the guide plate of the scraper chain is arranged in the groove of the driven wheel, so that the scraper chain is prevented from falling off from the driven wheel.
The utility model has the advantages that: because the inclined scraper is arranged, the inclined scraper can scrape the materials adhered to the bottom of the box, and manual cleaning is not needed when the machine is stopped; because the driven chain wheel is changed into a driven wheel with a smooth wheel surface, and the scraper chain wheel is provided with the guide plate, the problems of chain link accumulation and chain falling from the chain wheel caused by the length error of the chain links are avoided, and the smooth production is ensured.
Description of the drawings:
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;
fig. 3 is a side view of the driven wheel of the present invention.
The specific implementation mode is as follows:
the utility model is further illustrated with reference to fig. 1-3;
the automatic feeding device comprises a box body 1, wherein a feeding hole 2 is formed in the top of the box body, a discharging hole 3 is formed in the bottom of the box body, a driving chain wheel 4 and a driven wheel 5 are respectively arranged at the front part and the rear part in the box body through shafts, a motor speed reducer 6 is arranged at the front end of the box body, and a transmission chain wheel on a shaft of the driving chain wheel is connected with a chain wheel on an output shaft of the motor speed reducer through a chain; the scraper chain 7 is arranged on the driving chain wheel and the driven wheel; the method is characterized in that: the scrapers on the scraper chain wheel comprise a plurality of vertical scrapers 7-1 vertical to the bottom of the box and inclined scrapers 7-2 inclined forwards from top to bottom, and one inclined scraper is arranged at intervals of the plurality of vertical scrapers.
The wheel surface of the driven wheel is a smooth surface, and the middle part of the wheel surface is provided with a circle of annular groove 5-1 which is recessed towards the interior of the driven wheel; the guide plate 7-3 is fixed on the scraper chain wheel, and the guide plate of the scraper chain is arranged in the groove of the driven wheel, so that the scraper chain is prevented from falling off from the driven wheel.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
