The shovel positioning device is an improvement of the prior rock loader and belongs to the field of mine loading machinery equipment component. The shovel positioning device for the rock loader comprises a bucket elevating mechanism, a chain wheel and a lifting chain, wherein the chain wheel is arranged on the bucket elevating mechanism, and the lifting chain is arranged on the chain wheel. The shovel positioning device is characterized in that the bucket elevating mechanism is fixedly provided with a bracket, an electromagnetic housing is arranged at the top part of the bracket downwards and reversely, an electromagnetic core is arranged inside the electromagnetic housing, an adjusting bolt and an adjusting nut are arranged under the electromagnetic core, the adjusting bolt is fixedly arranged on the bucket elevating mechanism, the chain wheel is provided with a ratchet wheel, a pressure plate and a pawl are welded together and are arranged on a rotating shaft, the other end of the pressure plate is arranged on the electromagnetic core, and the pawl corresponds to the ratchet wheel. The shovel positioning device ensures that the bucket can be static at a certain position in air in the falling process, and improves the application performance of the product and the loading efficiency.
Description
Technical field
The utility model relates to a kind of dirt loader to be raised bucket mechanism and shovels device surely, is to the improvement of existing dirt loader, belongs to loading machine equipment component field, mine.
Background technology
Dirt loader is a kind of mine charging appliance, and its purposes is with ore or the rock haulage device of packing into, dirt loader by walking mechanism, raise bucket mechanism, scraper bowl part, control part and grade and form.
The function that dirt loader is raised bucket mechanism is that the scraper bowl dress of finishing dirt loader is got material, promoted that scraper bowl falls back to original position under scraper bowl, unloading, the action of gravity.The action of scraper bowl is finished under the tension of chain promoting, tension chain during motor drives sprocket rotation during energising, and the pulling scraper bowl upwards rises; The outage scraper bowl falls under action of gravity, owing to do not have fixed point, and can not static skyborne a certain position before scraper bowl lands.When the application of dirt loader, because dirt loader and haulage device have certain distance, scraper bowl has long time from rising to discharging, scraper bowl will promote and be unloaded to the outside of haulage device rapidly if switch on continuously, if the outage scraper bowl can not be still in a certain position in the lifting process, and can under action of gravity, scatter on the ground by the ore in the scraper bowl of automatic whereabouts, cause efficiency of loading to reduce.
Summary of the invention
What the purpose of this utility model provided that a kind of dirt loader scraper bowl can be still in aerial a certain position in dropping process decides the shovel device.
Spade-locating device for rock loader of the present utility model, comprise and raise bucket mechanism, sprocket wheel, promote chain, sprocket wheel is installed in to be raised in the bucket mechanism, promoting chain is installed on the sprocket wheel, it is characterized in that raising fixed installation one support in the bucket mechanism, electromagnet casing is inverted the top that is installed in support downwards, be the moving core of electromagnet in the electromagnet casing, the moving core of electromagnet below is provided with over against the position regulates bolt and adjusting nut, regulate bolt and be installed in and raise in the bucket mechanism, ratchet is installed on sprocket wheel, pressing plate and ratchet weld together and are installed on the turning cylinder, the other end of pressing plate is installed on the moving core of electromagnet, and ratchet is corresponding with ratchet.
During energising, raise bucket motor drives sprocket wheel and be rotated in a clockwise direction, be installed in the scraper bowl that lifting chain on the sprocket wheel is tightened up the pulling chain other end and upwards mention.Scraper bowl falls under the effect of gravity during outage, and the pulling sprocket wheel counterclockwise rotates.
During the electromagnet no power, the moving core of electromagnet is pushed down pressing plate and is moved down together under action of gravity, and pressing plate moves down
The ratchet that drive the is welded as a whole moving axis that rotates rotates counterclockwise, and ratchet separates with ratchet, and ratchet is free to rotate counterclockwise with sprocket wheel.
Scraper bowl falls need be when a certain fixed-site, connect electromagnet power supply, the moving core of electromagnet is upwards mentioned, drive pressing plate, ratchet clockwise rotate, ratchet withstands ratchet, ratchet stops to rotate counterclockwise with sprocket wheel, and the lifting chain that is installed on the sprocket wheel is static, and scraper bowl stops at a certain position thereupon.
On the support below the moving core of electromagnet the bolt of adjusting and adjusting nut are arranged, regulate the stroke and the position of pressing plate and ratchet.
Advantage of the present utility model:
Can make scraper bowl in dropping process, be still in aerial a certain position, improve the application performance and the efficiency of loading of product.
