Description
Technical Field
The invention relates to a chute used in a large-scale strip mine semi-continuous and continuous mining process, in particular to a chute with a rotatable feeding hole.
Background
In the semi-continuous and continuous mining process equipment of large-scale strip mines, between two mobile devices (such as a bucket wheel excavator, a self-moving feeder, a self-moving crusher, a self-moving transloader, a dumping machine and the like) or between a fixed device and the mobile device (such as a fixed crushing station and a mobile feeder), when unloading and receiving materials at a transloading point, because the devices are large-scale integrated devices, the devices have large weights and are inflexible to move, the conditions of difficult centering, delay, material leakage and the like are frequently generated, and the working efficiency is influenced.
Disclosure of Invention
In order to overcome the problems, the invention provides a chute with a rotatable feeding hole.
The technical scheme adopted by the invention is as follows: the device is formed by sequentially connecting an upper section chute, a rotating device and a lower section chute, wherein the upper section chute and the lower section chute are both cylindrical, the upper section chute is cylindrical and is also a feed inlet, the upper opening of the lower section chute is circular, and the lower opening of the lower section chute is square; the rotating device consists of a rotating motor and a reducer thereof, a reducer output pinion and a slewing bearing, wherein the slewing bearing comprises an inner ring and an outer ring, the outer ring is a big gear, the rotating motor and the reducer thereof are arranged on an upper-section chute, and the big gear and the small gear are meshed; the upper chute, the rotating device and the lower chute are connected in sequence, namely the upper chute is connected with the inner ring of the slewing bearing, and the lower chute is connected with the outer ring of the slewing bearing. When the motor is started, the upper and lower chute sections can rotate relatively.
When in use, the lower section chute of the invention is arranged on the receiving moving equipment. When the feeding mobile equipment discharges materials to the receiving mobile equipment, the upper-section chute is rotated to change the position of the feeding hole without moving the receiving equipment or the feeding equipment in a large range.
Compared with the prior art, the invention has the beneficial effects that: the upper-round lower-side chute of the invention is convenient for connecting the receiving equipment and the feeding equipment, the direction of the feeding port is changed by the automatic rotation of the chute at the upper section, the chute is convenient for fast centering with the feeding equipment, the material scattering and leaking are reduced, and the mining efficiency of the strip mine is further improved.

Fig. 3 is a schematic view of the present invention in use.
Wherein: 1-chute upper section, 2-rotating device, 3-chute lower section, 4-feed inlet detection device, 11-chute upper section wear-resistant lining plate, 21-rotating motor, 22-speed reducer, 23-pinion, 24-slewing bearing with big gear wheel, 31-chute lower section wear-resistant lining plate.
Detailed Description
Referring to fig. 1 and 2, an upper section chute 1, a rotating device 2 and a lower section chute 3 are sequentially connected, the upper section chute and the lower section chute are both cylindrical, wherein the upper section chute is cylindrical and is also a feed inlet, the upper opening of the lower section chute is circular, and the lower opening of the lower section chute is square; the rotating device consists of a rotating motor 21 and a speed reducer 22 thereof, a speed reducer output pinion 23 and a slewing bearing 24, the slewing bearing comprises an inner ring and an outer ring, the outer ring is a large gear, the rotating motor and the speed reducer thereof are arranged on the outer wall of the chute at the upper section, and the large gear is meshed with the small gear; the upper chute, the rotating device and the lower chute are connected in sequence, namely the upper chute is connected with the inner ring of the slewing bearing through a bolt, and the lower chute is connected with the outer ring of the slewing bearing through a bolt. The feed inlet detection device 4 is installed on the feed inlet. The inner wall of the chute at the upper section is provided with a wear-resistant lining plate 11, and the inner wall of the chute at the lower section is provided with a wear-resistant lining plate 31. The lower opening of the lower chute is square and is used for being connected with a receiving device (the receiving device generally has a square receiving opening, such as the upper opening of a crusher), and the upper opening is circular and is used for being connected with a rotating device. When the motor is started, the upper and lower sections of the chute can rotate relatively.
Referring to fig. 3, there is shown a top view of a self-moving crusher (receiving apparatus) 200 and a self-moving feeder 300 to which the present invention 100 is mounted. When the discharge opening of the self-moving feeder is not opposite to the feed inlet of the chute, the direction of the discharge opening of the feeder is required to be changed by continuously moving the crawler belt under the common condition. If the self-moving type feeder is used, the direction of the crawler belt is kept unchanged, and the discharge opening of the self-moving type feeder can be quickly inserted into the feed opening of the chute only by changing the direction of the feed opening at the upper section of the chute. The centering time of the two devices is reduced, and the mining efficiency is improved.
