Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction nozzle device for sucking and removing fallen minerals accumulated around a conveyer for powdery or granular material such as a belt conveyor, a stacker or a reclaimer.

[0002]

2. Description of the Related Art For example, a company such as an iron manufacturing industry uses a conveyor such as a belt conveyor, a stacker or a reclaimer as a means for handling a large amount of iron ore, coal, limestone, coke and the like. When the iron ore or other powdery or granular material is transported using the above-described transporting device, the powdery or granular material adhering to the belt surface sequentially drops while the belt is traveling on the return side, and the lower and both sides of the transporting device, that is, Deposit on the ground above. In addition, local accumulation of powdery particles is unavoidable at the transfer section of the belt conveyor.

As a method for removing the fallen minerals, excavation / scraping is performed manually, using a mechanical device, washing with water, or manually using a suction nozzle. However, the manual work method requires too much work. Further, in the method using a mechanical device, restrictions on the structure of a drive mechanism such as an arm cannot be avoided. For example, JP-A-62-2351
In the technique described in Japanese Patent No. 26, the suction nozzle is provided in the articulated arm, and its drive range is limited. In particular, since a space in the height direction is required, it is no longer possible to deal with the case where the above-mentioned transfer device is arranged in a plurality of rows or when other structures are close to the transfer device. The current situation. In addition, the water washing method requires a large capacity of water treatment equipment, and further requires a great load to treat the moist powder and granules.

[0004]

There are various forms and structures of powder and granular material conveying devices. For example, as a belt conveyor, the height from the ground to the return side belt is about 500 to 500.
800 mm, width 1000 to 3000 mm, length several meters to several hundred meters
Those within the specification range are maintained. Fallen ore deposits are accumulated around these transport devices under different conditions,
The unevenness of the deposition surface changes the relative distance to the suction nozzle, which not only lowers the suction efficiency but also causes the suction nozzle to plunge into the pile of deposits of minerals and disable the suction removal operation. There is a demand for a device that solves the above problem and effectively removes and recovers fallen minerals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The device of the present invention will be specifically described below with reference to the embodiments shown in the drawings. FIG. 1 is an explanatory view showing the outline of the work of sucking and removing fallen minerals by the device of the present invention. Then, the self-propelled carriage device 3 for sucking and removing the accumulated fallen minerals 2 such as granular materials
For this, the self-propelled carriage 3 operated by remote control is suitable.
As the drive structure of the self-propelled carriage 3, for example, a caterpillar drive device 4 can be used. Above trolley 3
Is equipped with a hose 5 for sucking and transporting fallen minerals 2, and the hose 5
Is equipped with a suction nozzle 6 and the rear end of the hose 5 is connected to a suction pump and a storage tank (not shown). As another drive structure of the self-propelled carriage 3, a wheel type (not shown) is used in place of the caterpillar type drive device 4 within a range where the height of the carriage that can enter the lower part of the transport device 1 can be maintained. You can

FIG. 2 is an enlarged explanatory view of the suction nozzle 6 portion.
The base end portion 7 of the suction nozzle 6 is swingably connected to and supported by a support member 8 provided on the front surface of the self-propelled carriage device 3. Specifically, the base end portion 7 of the suction nozzle 6 and the support member 8 are axially connected to each other with two shafts 10 and 11 rotatably in a horizontal direction and a vertical direction with a connecting member 9 interposed therebetween. The connecting member 9 and the shaft 11 are fixed, and the shaft 11 is connected to a motor 12 driven by fluid pressure. Therefore, the suction nozzle 6 can freely swing in the vertical direction with the shaft 10 as a fulcrum, and reciprocally rotates in the left and right directions with the motor 11 driven with the shaft 11 as a fulcrum.

The rear portion of the suction nozzle 6 which is swingably supported as described above is connected to the hose 5 with the flexible pipe 13 interposed. A copying device 14 is provided at the lower end of the suction nozzle 6. The copying device 14 directs the suction nozzle 6 in a substantially aligned state with respect to the uneven surface of the falling mine 2 and faces the surface of the falling mine 2 and the suction nozzle in opposition to the pressing force applied to the suction nozzle 6 during the suction operation. The function to keep the distance from the tip of 6 almost constant at all times is given. The copying device 12 uses a structure having a slidable sliding surface, and as described above, the suction nozzle 6 is required to move forward and backward on the surface of the mine ore 2 and move laterally. In order to exhibit the copying function in the movement, the bottom surface is configured with a dish type guide member.

The sedimentation state of the above-mentioned ore deposits 2 depends on the characteristics of the ore deposits, such as the particle size, particle size distribution composition, water content, viscosity, specific gravity, etc., and particularly the deposition surface of the ore deposits becomes smooth due to rainfall and the like. If it contains about 10% of water, it is deposited in a tight state. In order to effectively suck the fallen minerals 2 in such a deposited state, it is preferable that the distance from the depositing surface of the fallen minerals 2 to the tip of the suction nozzle 6 is as close as possible within the range of 10 to 30 mm. On the other hand, there are 2
It is efficient to suck as far as possible from a wide range within the range of 0 to 50 mm. Therefore, the copying apparatus 1
It is preferable that the mounting height position of 4 corresponds to the accumulation state of the fallen minerals 2 and the height can be freely adjusted by changing the fixing position of the bolt and nut, for example.

Since the present invention is configured as described above, even if the part where the deposits of the ore deposits 2 are relatively flat and the part where the deposits are abruptly raised coexist, they are provided at the tip of the suction nozzle 6. By the copying device 14, the suction nozzle 6 swings around the shaft 10 as a fulcrum, and the suction port of the suction nozzle 6 is directed to the deposition surface of the fallen minerals 2 in a substantially straight state, for example, 10 to 50 mm.
Since the interval can be set and maintained, the powdery or granular material can be stably sucked and collected. Further, by driving the motor 12, the suction nozzle 6 reciprocates in the left-right direction with the shaft 11 as a fulcrum, and is determined by the lengths of the base end portion 7 and the connecting member 9 when the traveling carriage 3 moves forward and backward. It is possible to suck the falling rocks 2 in the length range.

[0013]

According to the apparatus of the present invention, when the self-propelled trolley device 3 approaches the falling mine 2 accumulated around the conveying device 1, the suction nozzle 6 rotatably supported is dropped by the copying device 14. Following the uneven surface of the deposit of the minerals 2, it is possible to suck and recover the fallen ore with a stable suction efficiency.
