Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid fluid supply leveling device for stacking solid fluid such as earth and sand and leveling the surface thereof.

[0002]

2. Description of the Related Art In excavation work for tunnels, the shears (crushed rock fragments and earth and sand) generated by excavation of horizontal shafts and inclined shafts are piled up on a rail-type shear carrier (zuritro) by an off-loading machine. It is being carried out of the mine by car. This shear truck is typically 3-4 in length.
It is a box shape having a width of about 1 m and a height of about 1 to 1.5 m. In this shearing vehicle, the surface of the loaded skids is leveled by an operator in order to efficiently carry out the skids by stacking the skids properly.

[0003]

However, leveling the surface of the above-mentioned shear is a heavy labor and the working efficiency is not good. Slipping is a major factor that controls the tunnel construction speed, so it is required to be quick. Therefore, the present invention provides a solid fluid supply leveling device capable of supplying solid fluid such as earth and sand to the above-mentioned shear transport vehicle and mechanically leveling the surface.

[0004]

In order to solve the above-mentioned problems, the present inventor has proposed to move the supply position of the solid fluid by the conveyor and further move the scraper by utilizing the movement of the conveyor. Therefore, they have found that the intended purpose can be achieved, and have completed the present invention.

That is, the invention according to claim 1 is an apparatus for supplying a solid fluid such as earth and sand and leveling the surface thereof, and a conveyor for feeding the solid fluid laterally and the conveyor. And a conveyor moving means for moving the solid fluid back and forth in the transport direction so as to change the carrying-out position of the solid fluid, and moving with the conveyor on the solid fluid that is attached to the front end of the conveyor and is delivered by the conveyor and stacked. And a scraper that scrapes and evens the surface of the solid fluid.

According to a second aspect of the present invention, in the apparatus for supplying and leveling the solid fluid according to the first aspect, the conveyor supplies the solid fluid to the container, and the scraper. And a scraper elevating means for elevating the container between an upper position that is above the container and a lower position that is inside the container; A height sensor for detecting the height of the animal, and the scraper elevating means is operated based on the height of the solid fluid detected by the height sensor, and the solid fluid in which the scrapers are piled up is a container. And a scraper control means for lowering the scraper into the container so that the solid fluid inside the container is moved to a position where the height is low. A supply smoothing device of the solid stream animal in.

According to a third aspect of the present invention, in the apparatus for leveling and supplying the solid fluid according to the first aspect, the conveyor supplies the solid fluid to the container and the scraper. A scraper elevating means for moving up and down between an upper position that is above the container and a lower position that is inside the container; and a solid flow of each part in the container that is attached to the front end of the conveyor and moves with the conveyor. Based on the height sensor for detecting the height of the animal and the height of the solid fluid detected by the height sensor, the moving speed of the conveyor is such that the carry-out position of the conveyor is the solid fluid in the container. Slow when in a low height area,
It is a solid-fluid supply leveling device further comprising conveyor movement control means for controlling the conveyor movement means so that the speed becomes higher when at a high position.

[0008]

In the invention according to claim 1, by moving the conveyor itself by means of the conveyor moving means, the carry-out position can be changed back and forth in the carrying direction. Therefore, the solid fluid is piled up at one place. You can avoid getting into a state. The scraper attached to the front end of the conveyor moves together with the conveyor on the stacked solid fluids, so a power source dedicated to the scraper is not required, and the surface of the solid fluids can be efficiently scraped and leveled. You can

Here, the scraper can be raised and lowered as in the invention according to claim 2, but the lower end of the scraper can be positioned and fixed below the lower surface of the conveyor. In this way, when the height of the solid fluid becomes a certain height or more, the surface of the solid fluid is always scratched by the scraper.

In the invention according to claim 2, since the height sensor attached to the front end of the conveyor moves together with the conveyor to detect the height of each part of the solid fluid in the container, the solid in the container is detected. Based on the height of each part of the fluid, by appropriately operating the scraper elevating means to lower the scraper into the container, the portion where the height of the solid fluid is increased by the scraper is reduced. To allow surface leveling without spilling the solid fluid from the container.

According to the third aspect of the present invention, when the carry-out portion of the conveyor is located at a position where the height of the solid fluid in the container is low, the moving speed of the conveyor becomes slow and the height of the solid fluid becomes high. Since the moving speed of the conveyor becomes faster when the carry-out section is located at the part, the amount of the solid fluid supplied to the part where the height of the solid fluid in the container is low increases the height of the solid fluid. The amount of solid fluid supplied to the portion where the temperature is low becomes relatively small. Therefore, the solid fluid can be supplied substantially evenly throughout the container.

[0012]

According to the first aspect of the present invention, the conveyor moving means for moving the conveyor for feeding the solid fluid in the lateral direction to the front and rear in the conveying direction of the solid fluid is provided, and the conveyor is provided at the front end of the conveyor. Since a scraper that moves with the conveyor and scrapes and evens the surface of the solid fluid is attached, the solid fluid is supplied while changing the carry-out position so that the solid fluid does not pile up in one place. It is possible to scrape and level the surface of the solid fluid with a scraper without providing a source, and it is possible to enhance the work efficiency when the solid fluid is loaded in a container or at a specific place.

According to the second aspect of the present invention, in the one for supplying the solid fluid to the container, the height of the solid fluid at each part in the container which moves together with the elevating means for raising and lowering the scraper and the conveyor is set. Height sensor to detect,
A portion in which the height of the solid fluid in the container is lowered by stacking the solid fluid down the scraper based on the height of the solid fluid detected by the height sensor. Since the scraper control means for moving the solid fluid is provided, the surface of the solid fluid can be efficiently and surely leveled, which is advantageous for improving the work efficiency.

According to the third aspect of the present invention, a height sensor that moves together with the conveyor to detect the height of the solid fluid in each part of the container, and the height of the solid fluid detected by the height sensor. Since it has a means for controlling the moving speed of the conveyor based on the height, the amount of the solid fluid in the container is high in a portion where the height of the solid fluid is low, and relative to the portion where the height is high. The amount of the solid fluid can be uniformly supplied by uniformly supplying the solid fluid, which is advantageous for improving the work efficiency.

The supply conveyor 11, the conveyor moving means 13 and the scraper elevating means 14 are provided with a control means 16 for controlling the operations thereof.

The shearing frame 5 is provided with side walls 5a which are erected on both sides of the weighing conveyor 6 and the feeding conveyor 11, and has a charging port 5b opened on the upper surface thereof.
The front surface of the measuring conveyor 4 which is in front of the conveying direction is open. The conveyor 6 for measurement has an endless belt 19 on pulleys 17 and 18 provided at both front and rear ends.
It is a belt conveyor that is wrapped around. A drive motor 21 with a speed reducer is connected to the front pulley 17, and a belt tensioning device 22 is connected to the driven pulley 18 behind.

The upper end of the flapper 7 is pivotally supported on the front end of a bracket 23 provided at the upper front end of the shearing frame 5. The flapper height detecting means 8 detects the height from the conveying surface of the weighing conveyor 6 to the lower end of the flapper 7 based on the rotational movement amount of the flapper 7. The volumetric flow rate calculation means 9 calculates the cross-sectional area of the shear S passing under the flapper 7 based on the flapper height detected by the height detection means 8, and the cross-sectional area and the weighing conveyor 6 The volumetric flow rate of the shear S is calculated on the basis of the transport speed of

Like the weighing conveyor 6, the supply conveyor 11 is a belt conveyor in which endless belts 26 are wound around pulleys 24, 25 provided at the front and rear ends of the front conveyor 24. A drive motor 27 with a speed reducer is connected, and a belt tensioning device 28 is connected to a driven pulley 25 that follows.

As shown in FIG. 2, the scraper 12 has a "V" shape whose central portion projects rearward in the conveying direction of the supply conveyor 11, and the conveyor 1
1 is disposed in front of the conveyor 1 and is supported by arms 31 and 31 so as to be movable up and down on the left and right of the front end of the machine frame 11a of the conveyor 11. On the other hand, the scraper elevating means 14 is composed of a cylinder device, and the base end of the cylinder is pivotally supported on the upper end of the support bracket 32 protruding upward from the machine frame 11a, and the tip of the piston rod is attached to the scraper 1.
The scraper 12 is pivotally supported by the arm 31 of the No. 2 and moves the scraper 12 up and down between the upper position (see FIG. 3) protruding upward from the shear carrier 2 and the lower position inside the shear carrier 2. It is like this.

The ultrasonic sensors 15 are provided on each of the left and right ends of the machine frame of the supply conveyor 11.
The height of the shear S under the machine frame is detected based on the reflection time of ultrasonic waves.

The conveyor moving means 13 is a rack
A pinion type, in which a rack 33 extending in the transport direction is attached to the machine frame 11a of the supply conveyor 11, a drive motor 34 with a reduction gear is attached to the side wall 5a of the shearing frame 5, and the drive motor 34 A pinion (not shown) that meshes with the rack 33 is attached to the output shaft of the.

That is, the supply conveyor 11 is supported by the side wall 5a of the offset insertion frame 5 so as to be movable in the conveying direction of the shear S. Then, the conveyor moving means 13
The feed conveyor 11 has a forward feed end whose shear feed position (front end position) is positioned above one end of the shear transport vehicle 2 as shown in FIG. 1, and a shear transport vehicle 2 as shown in FIG. It is adapted to be moved between a rearward traveling end positioned above the other end of the.

The control means 16 includes the ultrasonic sensor 1
Based on the detected value of 5, the moving speed of the supply conveyor 11 is slow when the carry-out position of the conveyor 11 is at a low position of the shear S in the shear carrier 2 and is high. The operation of the drive motor 34 of the conveyor moving means 13 is controlled so that the speed becomes faster.

However, in the control of the conveyor moving means 13, when the supply conveyor 11 is retracted, control is performed so that the shearing transfer speed of the belt 26 is faster than the retracting speed. If the retreating speed of the supply conveyor 11 and the shearing transfer speed are the same, the belt 26 of the supply conveyor 11 does not substantially advance with respect to the weighing conveyor 6, and the supply conveyor 11 retreats. If the speed becomes faster than the shearing conveyance speed, the shear S supplied to the belt 26 of the supply conveyor 11 moves backward with respect to the measuring conveyor 6 without advancing, and the shearing S supplies with the measuring conveyor 6. Conveyor 1
This is because it will be bitten between 1 and 1.

Further, the control means 16 is based on the detection value of the ultrasonic sensor 15 and beside the piled portion of the shear S in the shear carrier 2 (on the side opposite to the portion where the shear height is low). The scraper elevating means 14 is operated so that the scraper 12 descends so that the piled shears S can be moved by the scraper 12 to a portion having a low shear height.

Further, based on the flow rate calculated by the flow rate calculating means 9 of the volumetric flow rate measuring apparatus 1, the control means 16 increases the flow rate, and thus the supply conveyor 1 is provided.
1 so that the transport speed of 1 and the moving speed of the supply conveyor 11 become faster, and the operation of the supply conveyor 11 and the conveyor 11 when the flow rate of the shear becomes zero.
The drive motor 21 of the supply conveyor 11 and the drive motor 34 of the conveyor moving means 13 are controlled so that the movement of the conveyor is stopped.

When the control means 16 detects that the shear height detected by the ultrasonic sensor 15 is substantially the same over the entire shear carrier 2 and is equal to or higher than a predetermined height, the shear means shifts. In addition to outputting a command to stop the injection of the shearing S into the shearing insertion frame 5 to the S loading section, the shear transport vehicle 2
An instruction to replace the shearing vehicle 2 is output to the vehicle maneuvering section.

Therefore, in the stacking machine, when the shear S is loaded into the shear loading frame 5 by a feeder or the like, the shear S drops onto the belt 19 of the weighing conveyor 6, and is conveyed by the belt 19 to be transported by the flapper 7. Is pushed up and falls onto the belt 26 of the supply conveyor 11. Then, this shear S is caused by the belt 26 of the supply conveyor 11.
Although it is conveyed by and is supplied to the shear transport vehicle 2, since the supply conveyor 11 itself moves back and forth in the shear transport direction, the carry-out position of the shear S is from the front end portion to the rear end portion of the shear transport vehicle 2. It does not move while moving, and the shear S is not concentratedly supplied to one location in the shear transport vehicle 2. For this reason, in the shear carrier 2, a portion where the shear S is high and a portion where the height of the shear S is low rarely occur.

However, in the above-mentioned shear transport vehicle 2, when a portion where the shear S is greatly raised as compared with the other is generated,
This is detected by the ultrasonic sensor 15. However, when the absolute amount of the shear S in the shear carrier 2 is small, even if the scraper 12 is lowered, the scrap S does not hit the shear S, so that the surface smoothing by the scraper 12 cannot be performed.

In this case, the moving speed of the supply conveyor 11 changes. That is, when the carry-out position of the supply conveyor 11 is on the raised portion of the shear S, the moving speed of the conveyor 11 is increased and the amount of the shear S supplied to the region is reduced, so that the carry-out position is high. When the conveyor 11 is located on a low area, the moving speed of the conveyor 11 becomes slow, and the amount of the shear S supplied to the area increases.
As a result, the height difference between the shear heights is reduced.

Next, as shown in FIG. 1, when a portion of the shearing vehicle 2 in which the amount of shearing S is loaded is large and the amount of shearing S is much higher than the other, the scraper elevating means 14 is shown. Is activated, the scraper 12 descends to the opposite side of the portion where the shear height is low as shown in the figure, and in that state, the supply conveyor 11 retracts, so that the scraper 12 rises up. While ruining the part, scrape the scrap S to a low height part,
Minimize the difference in height of shear.

While the surface of the shear S is leveled in this way,
Since the new shear S is supplied on top of this, this new shear S is prevented from spilling from the shear carrier 2, and the shear S enters every corner of the shear carrier 2. When the shear height is substantially the same over the entire shear transport vehicle 2 and becomes equal to or higher than a predetermined height, the injection of the shear S is stopped and the shear transport vehicle 2 is replaced.

If the amount of shear S calculated by the volumetric flow rate measuring device 1 increases, the above-mentioned supply conveyor 1
Since the conveying speed of 1 and the moving speed of the supply conveyor 11 are high, the slip-out is not delayed. Further, when the amount of shear is small, the transport speed of the supply conveyor 11 and the moving speed of the supply conveyor 11 are slow, and when the amount of shear S is zero, the operation and movement of the conveyor 11 are stopped. Therefore, waste of power is eliminated.

Although the present invention is an example in which the present invention is applied to the extrusion of the above-mentioned embodiment, it is needless to say that the present invention can also be applied to the treatment of powdery particles or other solid fluids.
