BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for measuring and discharging a certain amount of powder or granular material, and particularly in civil engineering work.
The present invention relates to a device for measuring and discharging powdered granules such as bulk cement and lime, which are carried into a work site such as a road by a tank truck, at the work site.

[0002]

2. Description of the Related Art Generally, in civil engineering work, bulk cement and lime are discharged and spread on a section divided into a certain area at the work site. Conventionally, the method is as follows. Has been.

In the case of using the packed powder and granules, it is a method of arranging and using cement or lime, which is quantitatively weighed in a factory (1000 kg, 40 kg, etc.), in a predetermined area on site. However, this method requires a crane for hoisting a 1000 kg bag, and
The one packed in 0 kg bag has to be manually operated, which causes a problem that many workers are required. Further, in the case of 40 kg bag packing, there is a problem that the unit price of the material is high and empty bags need to be processed, and in the case of 1000 kg bag packing, it is relatively expensive compared to tank truck transportation.

When a tank truck is used, it is a method in which the tank truck is loaded in bulk, put in a weighing box, and sprayed over a predetermined area. This method is administratively
The volume is multiplied by the specific gravity to convert the weight, and the total weight of the tank trucks is used to manage the volume of each tank truck. Compared to the above method, the material cost is lower and the subdivision is arranged. On the other hand, there is a problem that dust is generated at the time of subdivision arrangement, calibration is required before spraying to convert the volume to weight, and dust is generated when discharging from the tank truck vehicle is there.

In contrast to the above, cement or the like transported by the tank truck is temporarily stored in a large storage tank,
A device for distributing from this tank to a weighing hopper has been proposed as Japanese Utility Model Laid-Open No. 58-127328. However, since the storage tank of this metering and feeding device is equal to or larger than the tank of the tank truck, the entire device is considerably large and movable,
It cannot be used by moving it to any place.

[0006]

Therefore, the problem to be solved by the present invention is to solve the problems of the prior art, such as how to make a powder or granular material such as cement by forming the device lightweight and compact. The object is to provide a device that can accurately measure and supply even at various work sites.

[0007]

The present invention has been made for the purpose of solving the above-mentioned problems, and its construction is such that a discharge portion is provided at a lower portion and a bag filter is attached at an upper portion, and a receiving portion is provided at the bag filter. A flexible bag body for accommodating the provided powder and granules, and a measuring device such as a load cell having a hook for suspending the bag body and for measuring the weight of the powder or granules supplied to the bag body, and It is characterized in that it comprises a movable hanger that is formed in a substantially gate-like shape when viewed from the front and has a plane shape that allows the bag body to be substantially accommodated.

That is, the device of the present invention comprises a bag filter provided with a discharge part at the bottom of a bag for containing powder particles such as cement, and a receiving part for the powder particles in communication with the upper part of the bag. The bag body is hung on a hanger equipped with a weighing device such as a load cell, which is a frame of a size capable of suspending the bag body, and the bag filter is attached to the receiving portion provided on the bag filter. Connect the supply pipe of the tank truck and measure the powder particles such as cement from the tank truck while pumping them into the bag body.When the supply amount reaches the specified amount, stop the pumping and stop the cement from the bag discharge section. Since the device is designed to be discharged, the entire device is extremely compact and lightweight. Therefore, bring this device to the civil engineering work site and set it at the required place, and place cement etc. at the place as described above. After discharging, the next piece By moving to the same way as above, it is possible to efficiently supply cement and the like, and moreover, the work of moving and installing these is sufficient for one worker because the device is compact and lightweight. You can do it.

If a recorder for recording the amount measured by a weighing device such as a load cell is attached to an appropriate place on the hanger and a receipt is issued for each weighing by the recorder, the entire supply can be achieved. The amount can be accurately grasped.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a front view of an example of the device of the present invention, and FIG. 2 is a diagram showing a state in which cement or the like is supplied to a work site using the device.

In the figure, 1 is a bag body containing a cement or the like provided with a discharge part 2 at the lower portion, 3 is a bag filter connected to the upper portion of the bag body 4, and 4 is a cement or the like provided on the bag filter 3. The receiving part, 5 is a hanger of a gate type, a cantilever type, etc.
Weighing device 6 with a hanging hook 7 such as a load cell on the top
Is attached. Reference numeral 8 denotes a recorder attached to an appropriate portion of the hanger 5 in association with the weighing device so that the measured amount can be taken out as a receipt.
Reference numeral 9 is a belt which is hung around the bag body 1 and whose upper end is locked to the hanging hook 7. In the figure, 10 is a supply pipe of the tank truck T.

In the device of the present invention constructed as described above, the hanger 5 is arranged at an appropriate place on the work site, and the belt 9 is wound around the bag 1 to suspend the upper end of the belt 9 from the hanging hook 7. , The supply pipe 10 of the tank truck L is connected to the receiving portion 4 of the bag filter 3,
When the cement or the like is pressure-fed to the receiving portion 4, the air to be pressure-fed is discharged from the bag filter 3 and the cement or the like is supplied into the bag body 1, while the amount of the cement or the like is measured by the measuring device. When the amount of cement or the like in the bag body 1 reaches a predetermined amount, the pumping is stopped and the cement or the like is discharged from the discharge portion 2 of the bag body 1. When the supply of cement or the like to one location is completed in this manner, the hanger 5 is moved to the next location and the same operation as described above is repeated, so that the operation of supplying the cement or the like can be performed efficiently. Further, since the amount of cement or the like supplied is accurately measured by the measuring device, the problems in the conventional method are eliminated. still,
If the discharge portion 2 provided in the bag body 1 is opened by a so-called one-touch operation efficiency is further improved.

[0013]

Since the present invention is as described above, the working efficiency is improved as compared with the conventional method, the generation of dust is prevented, and the amount of cement supplied can be accurately measured. Since the granular material is stored in a flexible bag that can be expanded and contracted and weighed, the weight of the device is not bulky, and
Since it can be easily moved and installed at a desired place and used, it is suitable as a device for measuring and discharging powder or granular material such as cement that is brought into a civil engineering work site for use.
