Open automatically. Therefore, the bag mouth of the sandbag 6 is opened until it cannot be further expanded, and the bag mouth is opened by a pair of flap type gates 28, 28.
It can be fixed in a stretched state.

Next, when a hand switch 36 (see FIG. 2) provided near the chute 21 is turned on, the cylinder 23 is operated to advance the earth and sand extruding device 22 toward the passage outlet 20. As a result, a fixed amount of soil of one bag of sandbag 6 in the sediment receiving section 25 discharged from the sediment discharge port 17 by the screw conveyor 15 is extruded, and the passage outlet 2

Thereafter, when the operator turns the operation lever 35 provided on the side plate 28b (the side opposite to the release operation pin 32) of the flap type gate 28 with a force stronger than the urging force of the torsion coil spring 27, the gate 28 closes. The opening of the bag mouth containing the earth and sand is released. At this time, when the operation lever 35 is further rotated and the locking concave portion 31 reaches the position of the guide pin 33, the guide pin 33 connected to the release operation pin 32 jumps out due to the urging force of the compression spring 34. Since the flap type gate 28 returns to the protruding position, the locking recess 3
1 is locked by the guide pin 33 and fixed (locked) to the closed position.

The sandbag 6 filled with earth and sand in this manner is
Next, the sheet is sent to the binding unit 40 to perform a binding operation for closing the bag mouth. This binding unit 40 is shown in FIGS.
As shown in FIG. 8, a free roller conveyor 4 for transporting the sandbags 6 horizontally from the above-described filling operation position to the binding operation position in the horizontal direction, the bag opening of the sandbags 6 is squeezed, and the sandbags are bound with a clip. Binding machine 41 for closing
And a bundling machine vertical movement device 50 that holds the bundling machine 41 in a state of maintaining the weight balance in the up-down direction and enables the up-down movement.

The free roller conveyor 4 is used for laterally moving the sandbag 6 filled with earth and sand, and a large number of free rollers 4a protruding from the transport surface are freely rotated in the lateral (transport) direction. This allows the sandbag 6 to slide on the transport surface. This free conveyor 4
It is always mounted on the vehicle together with the sand blasting machine 10, and is used by being installed on the ground behind the loading platform during sand blasting.

The bundling machine 41 squeezes (bundles) the bag mouth of the sandbag 6 and can bind the squeezed bag mouth by deforming and caulking an aluminum clip generally. It is. The binding machine 41 includes a handle lever 42 that is operated during a binding operation, and an actuator 44 that operates by opening the valve by pressing the pneumatic or hydraulic valve opening / closing pin 43 when the handle lever 42 is closed. I have. Then, the actuator 44
When the is operated, the clip is swaged around the focused portion of the bag mouth by the stapling principle, so that the bag mouth is tightly bound and closed.

The binding machine 41 described above is attached to the binding machine vertical moving device 50. The bundling machine vertical moving device 50 enables the binding position (height) of the sandbag 6 to be adjusted with one touch according to the filling amount of earth and sand, and the bundling machine 41 is a slide unit of a linear way (LM guide) 51. And the weight of the binding machine 41 is balanced with the tension of the coil spring 52. That is, the binding machine 41 is configured to control the tension of the coil spring 52 and the linear way 51.
The weight is kept balanced in the vertical direction through the guides. Therefore, the binding machine 41 can be easily moved to a desired position simply by pushing the binding machine 41 lightly in either direction.

The binding unit 40 thus configured
The operator grasps the bag mouth filled with earth and sand from the filling work position below the bag opening device 26 described above, and moves the free roller conveyor 4, for example, to the fixed position of the binding work shown in FIG. When the handle lever 42 of the binding machine 41 is pressed, the actuator 44 operates, and the clip is pushed and deformed and caulked by the stapling principle, so that the bag mouth is bound. At that time, by keeping the weight of the binding machine 41 in a state of being balanced with the tension of the coil spring 52 so that the binding position can be adjusted to the filling height of the earth and sand, when the worker binds the bag, The binding machine 41 slides up and down only by applying a slight force with the finger of the hand.

The operation of the sand blasting machine and the sand blasting vehicle having the above construction will be described below in accordance with the procedure of the sand blasting work. As shown in FIG. 1, this sandbag-generating vehicle normally stands by with necessary equipment such as a sandbag-generating machine 10, a diesel generator 2, and a free roller conveyor 4 loaded on a truck 1. Then, as soon as the dispatch request is issued, the truck 1 can be driven to move to the site. During traveling, the sand blasting machine 10 is fixed near the center of the bed of the truck 1, so that the weight balance is relatively good and traveling stability can be ensured.

When this sandbag construction vehicle arrives at the site,
Unload equipment such as the free roller conveyor 4 loaded on the back of the loading platform and stop the sandbag forming machine 10 (not shown).
Is released and moved to the sandbag formation position on the rear end side of the loading platform. This moving operation is smoothly performed by the wheels 61 rotating on the rails 63 when about two workers push the soil moulder 10. Note that the sandbag forming machine 10 that has reached the sandbag forming position is securely fixed by a stopper device (not shown), and as shown in FIG.
A belt conveyor 5 and a free roller conveyor 4 for transporting soil and sand are arranged at predetermined positions.

When the preparation of the sandbag is completed,
The belt conveyor 5 is operated to transport the earth and sand, and the hopper 1
Supply into 1. At the same time, the bridge breaker 14 and the screw conveyor 15 installed in the hopper 11 can also start operation (operate by turning on the button of the hand switch). The earth and sand that has fallen from the belt conveyor 5 to the earth and sand inlet 12 passes through the earth and sand sorting device 13 and is supplied into the hopper 11, where foreign matters such as large stones are removed. The earth and sand that has passed through the earth and sand sorting device 13 is sent to the earth and sand discharge port 17 of the hopper 11 by the screw conveyor 15 while being loosened by the rotating bridge breaker 14.

The principle of the screw conveyor 15 is a positive displacement type, and therefore, the amount of earth and sand discharged can be adjusted by changing the number of revolutions. In other words, an approximately constant amount of soil (one batch) for one bag of the sandbag 6 can be ensured by keeping the operation time per operation of the screw conveyor 15 constant. Further, even if an attempt is made to supply a fixed amount of earth and sand for one bag of sandbags, the speed of the screw conveyor 15 can be changed within a predetermined range because the amount fluctuates under the influence of the properties of the earth and sand such as viscosity. For example, for viscous earth and sand, the rotation speed of the screw conveyor 15 is reduced, and the operation time of one batch is set longer accordingly. In order to control the operation time of one batch, an automatic timer may be used to automatically stop after a predetermined time has elapsed from the start of operation.

Before the screw conveyor 15 is operated to supply one batch of earth and sand, an empty sandbag 6 is supplied.
It is necessary to expand the bag mouth and fix it to the earth and sand outlet 21a of the chute 21. The bag opening device 26 is used for this operation. First, one flap-type gate 28 is opened and the other flap-type gate 28 is closed. The open flap gate 28 is urged in the opening direction by the torsion coil spring 27. In the closed state of the flap type gate 28, the locking recess 31 is locked to the guide pin 33 by the action of the stopper mechanism 29.
For this reason, the bag mouth of the sandbag 6 opened by the worker's hand,
One of them can be easily put on the outside of the narrowed flap type gates 28, 28 in the closed position, and when the release operation pin 32 is pressed in this state, the flap type gate 28 in the closed state becomes the guide pin 33. Released from the lock by
It opens automatically under the urging force of the torsion coil spring 27.
As a result, the bag mouth of the sandbag 6 is pushed and expanded to the pair of flap-type gates 28, 28 whose width is increased, and is fixed to the earth and sand outlet 21 a of the chute 21 in that state. At this time, the lower end of the sandbag 6 is placed at the sandbag creation work position on the free roller conveyor 4, but in order to facilitate the work of transferring to the binding position after filling, the tray is placed on the free roller conveyor 4. Place a tray 37 like this,
The lower end of the sandbag 6 may be placed on the receiving tray 37 and transported integrally. Thus, the preparation of the sandbag 6 for receiving one batch of earth and sand from the screw conveyor 15 is completed.

Subsequently, as described above, the screw conveyor 15 is operated for a predetermined time, and one batch of earth and sand is sent out from the earth and sand discharge port 17 to the earth and sand discharge passage 18. As a result,
One batch of earth and sand falls from the passage entrance 19 communicating with the earth and sand discharge port 17 to the earth and sand receiving section 25 having an upper surface opening.
Next, the operator confirms that the preparation for operation of the earth and sand extruder 22 has been completed, and then operates the hand switch 36 to turn it on. It should be noted that the fact that the earth and sand pushing device 22 is ready for operation may be displayed by a method such as turning on a confirmation lamp provided adjacent to the hand switch 36.

When the hand switch 36 is turned on in this way, the cylinder 23 of the earth and sand extruder 22 is operated,
Passage exit 2 with sediment receiving section 25 along with one batch of sediment
Since it is pushed toward zero, the earth and sand is filled into the sandbag 6 through the chute 21 from the lower surface opening of the earth and sand receiving section 25. The earth and sand bag 6 having been filled with the earth and sand is released from the fixing of the bag mouth by the operator pushing the operation lever 35 to rotate the flap type gate 28 from the open position to the closed position. Is further pushed in the same direction to keep the flap type gate 28 in the closed position by the stopper mechanism 29. The sandbag 6 having been filled with the earth and sand is conveyed on the free roller conveyor 4 from the sandbag forming operation position to the binding operation position, and the earth and sand extruder 22 returns to the original state (position). The screw conveyor 15 that has been stopped after the elapse of the predetermined time starts operating at the same time as the earth and sand extruder 22 returns to the original state, and is similarly operated for the operation time of supplying one batch of earth and sand. .

The sandbag 6 filled with the earth and sand is closed by the binding device 40 after the worker grasps the bag opening by hand and transports it to the binding operation position, and then performs the final binding operation. . The bundling operation position is provided substantially concentrically in the lateral direction (the vehicle width direction of the truck 1) with respect to the sand blasting operation position. Therefore, when the bag bag 6 is moved to the binding position of the binding machine 41 at the binding position where the sandbag 6 is conveyed substantially horizontally and laterally on the free roller conveyor 4, and the handle lever 42 is pushed in, the bag bag is opened. Are squeezed and bound by clips. The operation of the binding machine 41 will be described in more detail. When the handle lever 42 is rotated, the bag mouth is narrowed, and at the same time, the handle lever 42 is rotated.
Pushes the pneumatic or hydraulic valve opening / closing pin 43, the valve opens and the actuator 44 operates. When the actuator 44 operates, the aluminum clip is deformed and crimped around the narrowed bag mouth, so that the bag mouth is bound and firmly closed by the clip.

When performing the above-described binding work, the binding height varies depending on the size of the sandbag 6 and the amount of earth and sand to be filled. In such a case, the weight of the binding machine 41 is reduced by the coil spring 52 due to the function of the binding machine vertical moving device 50.
Therefore, the worker can easily move the binding machine 41 in the up-down direction only by lightly touching it. Therefore, the height of the binding machine 41 can be adjusted, and the binding operation can be performed at an appropriate position.

FIG. 9 is a flow chart showing an automatic operation mode in which the operation time of one batch of the screw conveyor 15 is set in accordance with the properties of the earth and sand, and a fixed amount of earth and sand is supplied. In this automatic operation mode, operation of the screw conveyor 15 is instructed for an arbitrary time in consideration of various conditions such as the properties of earth and sand and the size of the sandbag 6, and the operation of the screw conveyor 15 is continued until the arbitrary time elapses. When the operation for an arbitrary time is completed, 1
A batch of earth and sand is secured in the earth and sand extruder 22. After that, it is confirmed that the operation preparation of the earth and sand extruder 22 is completed, and the hand switch 36 is turned on. As a result, the earth and sand extruder 22 advances, and the sandbag 6 is filled with one batch of earth and sand. When the filling is completed, the earth and sand extruder 22 moves backward, and this is repeated as one cycle. Therefore, if the number of rotations of the screw conveyor 15 or the operation time of the automatic timer of the operation time is appropriately set according to the properties of the earth and sand, one batch of earth and sand can be sequentially supplied as described above.

Thus, the worker inserts the sandbag 6 into the bag opening device 26 and presses the release operation pin 32 to push the sandbag 6.
Is fixed to the chute 21 with the bag mouth open, and then the hand switch 36 is turned on, and the screw conveyor 1 is moved from the hopper 11 by a preset automatic operation.
The earth and sand extruding device 22 advances the earth and sand from which a certain amount of the sand bag has been discharged by the sandbag 5 through the chute 21 and the sand bag 6 from the chute 21.
Fill. Next, the operator presses the operation lever 35 to release the fixing of the sandbag 6, and moves the binding bag 40 to the binding unit 40 by grasping the bag opening. By repeating such operations and operations, a large amount of sandbags 8 can be formed. The sandbags 8 thus created are transported and stacked to a sandbag installation place by using a belt conveyor (not shown) connected near the binding operation position of the free roller conveyor 4. The hopper 11
Conveyor belt 5 for transporting soil and sand and completed sandbags 8
Auxiliary equipment such as a belt conveyor that conveys to the installation location changes its length and number according to the situation at the site, so here, the sandbags are not loaded on the truck 1 on which the sandbag forming machine 10 is mounted, It is preferable to transport a sufficient amount of auxiliary equipment by a separately prepared support vehicle.

And the driving operation is simple. In addition, since it is equipped with a sediment sorting device and a bridge breaker, it can handle a wide range of sediment properties that must be procured locally. And the filling amount of earth and sand can be easily adjusted by appropriately changing the rotation speed and the operation time by adopting a positive displacement screw conveyor, and an arbitrary setting is possible.

The features and effects of the present invention will be described in more detail below. (1) The running stability can be maintained by arranging the sand blasting machine near the center of the transport vehicle during the traveling movement of the sand blasting vehicle. In addition, when arranging the sandbag after arriving at the site, the sandbag can be created while the sandbag is being pulled out to the rear of the vehicle and mounted on the vehicle, so that the operation can be started quickly and good workability can be provided. (2) Since the earth and sand put into the hopper is conveyed by the screw conveyor while being loosened by the bridge breaker, it can sufficiently cope with a wide range of earth and sand properties, and the bag and sand from the earth and sand discharge port at the bottom of the hopper are integrated. Sediment can be quantitatively discharged. The fixed amount of the bag can be arbitrarily set by changing the operation time (controlled by a timer or the like) and the number of revolutions of the screw conveyor. (3) A certain amount of earth and sand discharged from the earth and sand discharge port at the bottom of the hopper is discharged one bag at a time by an earth and sand extruder provided below the earth and sand discharge port. This operation
When the operator turns on the hand switch, the extruder moves forward and drops from the chute connected to the extruder into an empty sandbag and is filled, so that the operation is extremely easy. (4) When the worker inserts an empty sandbag into the lower part of the chute and presses the release operation pin, the flap-type gate is opened and the bag can be fixed with the bag mouth extended (fully open). After filling the bag opening with chute through the chute, the worker can pull the operation lever to close the flap type gate and release the fixation of the bag containing the earth and sand. The work is also easy. (5) When a worker takes out a sandbag containing earth and sand from a bag opening device, transports the bag to a binding position, binds and closes the bag opening, and uses a stapling principle as a binding machine (commonly called a clipper). Is adopted. This binding machine requires vertical positioning according to the height of the binding position, which differs depending on the amount of earth and sand.However, the function of the binding machine up / down moving device allows vertical movement only by applying a slight force with the fingers of the hand. , The binding machine can be easily adjusted to the optimal binding position, and the actuator is operated by operating the handle lever to bind, so that the force required for the binding operation is relatively small.

As described above, the sand blasting machine is mounted on a truck such as a truck to facilitate transportation and movement to the site such as wind and flood damage, and a disaster is required because the sand blasting operation is carried out while being carried on the vehicle. Preparation for on-site operation will be quick. And the bagging and bundling of earth and sand that requires labor is almost automatically operated, and the installation of complicated sandbags can be done with one touch, so the operation work of the operator is simple and the burden is reduced,
Since a large number of sandbags can be created by a small number of people, there is an effect that it is possible to greatly reduce the number of dispatched personnel and prevent a disaster from occurring.
