Example ten:
the embodiment is a bulk cargo yard moving and material taking method using the integrated machine of the embodiment, and the method comprises the following steps:
step 1, entering an operation station: the vehicle body of the all-in-one machine is rotated, the material taking device, the material rake and the baffle are positioned in front of the chassis, and the walking mechanism is started to move the all-in-one machine to the edge of the material pile and enable the material taking device to be along the edge of the material pile in the long direction.
In general, there are several stacking methods for bulk material stacking: most commonly, the cone, or elongated pyramid, or irregular cone. However, the basic shape of all the stockpiles is a cone with a large upper part and a small lower part, the cone is provided with inclined side surfaces, and the part of the edge of the cone, which is close to the ground, is lower, and the height of the edge of the cone is higher towards the center of the stockpile.
In view of these characteristics of the stockpile, this embodiment has adopted the automobile body that can 360 degrees rotations for the chassis, makes extracting device can be convenient the place ahead of going to the chassis to propelling to stockpile central direction under the drive of chassis, the automobile body can also rotate the side to the chassis simultaneously, utilizes the walking adjustment extracting device on chassis to follow the position at stockpile edge.
The integrated machine enters the operation station, the actual action is to adjust the relative rotation angle of the chassis and the vehicle body, and meanwhile, the relative position of the integrated machine and the material pile is adjusted by utilizing the walking function of the chassis, so that the integrated machine occupies a position convenient for material taking, and the material taking efficiency is improved.
Step 2, connecting with a belt conveyor: and adjusting the position of the all-in-one machine to enable the output end of the material taking device to be connected with the input end of the belt conveyor to form a conveying chain.
The purpose of the integrated machine is to convey bulk materials to a belt conveyor, and therefore, the integrated machine needs to be matched with the belt conveyor to work, so that the input end of the belt conveyor is connected with the output end of the integrated machine, and the bulk materials output by the output end of the material taking device fall on the belt conveyor. Therefore, after the integrated machine enters the operation station, the position of the belt conveyor needs to be adjusted, so that the input end of the belt conveyor is connected with the output end of the material taking device, and a conveying chain is formed. The position of the belt conveyor also needs to leave a room for the all-in-one machine to push towards the center of the material pile, and the position of the belt conveyor does not need to be adjusted within at least one section of pushing.
In general, in the process that the all-in-one machine enters the operation station, the rake is usually swung and lifted to the highest point for safety, after the operation position is adjusted, the rake is firstly put down, the swing angle of the rake is adjusted, the inclination angle of the rake is close to the inclination angle of the hopper, but the rake is not inserted into the stockpile, so that a room for pushing towards the center direction of the stockpile is reserved for the all-in-one machine. The swing angle of the rake is adjusted mainly by the winding of a steel wire rope by a winch, and the rake is put down by the extension of the steel wire rope.
In the process of transition and operation station adjustment of the integrated machine, in order to protect each scraper of the material taking device, the material taking device is lifted under the driving of the connecting arm, so that the material taking device is away from the ground for a certain distance. And need adjust the distance on extracting device and ground when reacing the operation position to the bulk cargo can be stayed extracting device's scraper blade below, and the scraper blade is scraped the bulk cargo away in addition. When the material taking device is put down, the material taking device can be started to run at a low speed in order to protect the scraper, so that the scraper can be slowly pushed into a material pile, and the scraper is protected to the maximum extent when the speed of the scraper is gradually increased.
Step 5, taking materials: and starting the chain driving mechanism, wherein the chain drives the scraper to run, and the material below the material taking device is driven to the belt conveyor at one end of the scraper.
The scraper moves forwards along the direction of an arrow B in figure 2 under the pulling of the chain, bulk materials enter the front part of the scraper (the direction of an arrow C in figures 3 and 4) from the side surface of the scraper and are pushed by the scraper to move forwards, when the bulk materials reach the output end of the material taking device, the scraper is gradually lifted along with the chain and the chain wheel, and the bulk materials fall on a belt conveyor 6 (a dotted line table for the right side of figure 2). The scraper blade is constantly arranged to drive the bulk cargo to enter the belt conveyor, and the belt conveyor conveys the bulk cargo away.
When the material at the edge of the material pile is conveyed by the material taking machine, the edge of the material pile collapses, bulk materials continuously enter the material conveying device, but the material pile stops collapsing when the material pile collapses to a certain degree, and at the moment, the interference of the material rake is needed to make the material pile collapse continuously so as to facilitate the material taking device to convey materials. The interference of the material rake is that the material rake is put down, when the material loosening nail (rake teeth) is inserted into the material pile, the rake rack drives the rake teeth to reciprocate left and right, the rake teeth inserted into the material pile agitate the material pile to form interference, and the material pile continuously collapses.
And 7, advancing: and when the materials at the current position are taken away and the interference of the rake can not make the materials above continuously slide, starting the travelling mechanism to push the integrated machine to the center direction of the material pile or move the integrated machine to the next material pile operation station, and repeating the material loosening and taking processes until the operation requirement is finished.
When the interference of the rake on the material pile can not make enough bulk material fall to the front of the scraper of the material taking device, the bulk material at the current position of the integrated machine is almost conveyed away, and the integrated machine needs to be pushed towards the center of the material pile to find another operation station convenient for taking materials, so as to continue the material taking operation. In the process of taking materials, pushing, re-taking materials and re-pushing, the bulk materials are continuously loaded on the belt conveyor, and the belt conveyor is connected with a loading station or other transport machines to continuously transport the bulk materials away.
The integrated machine needs to be kept connected with the belt conveyor after the propelling and moving processes so as to ensure that bulk materials are correctly conveyed away.
Finally, it should be noted that the above only illustrates the technical solution of the present invention, but not limited thereto, and although the present invention has been described in detail with reference to the preferred arrangement, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solution of the present invention (such as the connection with the belt conveyor, the form of the scraper, the form of the chassis and the car body, the sequence of steps, etc.) without departing from the spirit and scope of the technical solution of the present invention.
