DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a sandbag making machine having a novel configuration.

Conventionally, this type of device is as follows.

In other words, restoration work using sandbags is often carried out as an emergency treatment for abnormal river flooding. However, since such work requires manual production, it has become difficult to secure labor.

The present invention aims to fully solve this problem, and details of embodiments thereof will be described below with reference to the drawings.

[Embodiments of the invention] Examples will be described with reference to the drawings.

1 is a sandbag making machine of the present invention.

The configuration is such that a weighing box 2 is supported at a predetermined height on the top surface of the base frame 6, and a hopper 3 that communicates with the weighing box 2 is connected to the top surface of the weighing box.
The weighing box 2 is provided with an extrusion device 4 for pushing out the earth and sand in the weighing box, and the hopper 3 has front and rear inclined surfaces 3A,
3B and the left and right inclined surfaces 3C and 3D that are orthogonal to the inclined surfaces 3A and 3B are configured in the shape of an inverted pyramid, and the left and right inclined surfaces 3C and 3D are configured to be variable, and the hopper 3 has a An agitator 7 is disposed, a discharge port 2B having a lid 2A that can be opened and closed is formed at the tip of the weighing box 2, a stuffing device 5 is disposed in the discharge port 2B, and the stuffing device 5 is A rotary cylinder 5C is rotatably fitted onto a fixed shaft 5B having a guide plate 5A at the lower end, and a pair of upper and lower brackets 5D, 5E are radially arranged on the rotary cylinder 5C.
A vertical guide chute 5F is fixed to the upper bracket 5D, and a reversing plate 5G is connected to the lower bracket 5E so as to be able to rise and fall freely using a horizontal pin P as a branch. Concave stepped portion 5 formed in a portion of the guide plate 5A
I, configured to respond by the convex step portion 5J,
On the other hand, a bag presser 5H is provided on the outer periphery of the chute 5F, which opens and closes the chute 5F in conjunction with the reversing plate 5G.

Therefore, each component will be explained in turn.

The lower ends of the inclined surfaces 3C and 3D in the hopper 3 are configured to be variable around bearings 3C' and 3D' provided in the front-rear direction, and these inclined surfaces 3C and 3
Between D and the base frame 6 are the inclined surfaces 3C and 3D.
A cylinder S is provided to raise and lower the surface. Therefore, when this cylinder is operated, the inclined surface 3
C and 3D move toward the center of the hopper 3.

The guide plate 5A is configured in the shape of a flat disk, and the roller 5G' provided on the lower surface of the reversing plate 5G is connected to the outer peripheral edge 5 of the upper surface of the plate 5A.
Rolls along A′.

Therefore, a concave step portion 5I and a convex step portion 5J are formed on the upper outer peripheral edge 5A' of the plate 5A for raising and lowering the reversing plate 5G. As mentioned above, the guide chute 5F is vertically fixed to the bracket, and is designed so that it gradually comes to the front lower part of the discharge port 2B as the rotary drum rotates.

A protrusion 5F' for ensuring support of the sandbag 8 is attached to the lower end of the outer wall of the chute 5F.

The bag presser 5H consists of a pair of front and rear arm bodies 5H' that clamp the chute 5F from the outside,
The vertical shaft 5 installed at the base of this arm body 5H'
H'' is connected to the bracket 5D so as to be openable and closable.

A spring 5K is stretched between the pair of arm bodies 5H' to draw the arm bodies inward.

5L is a passive metal fitting disposed to face each other between the pair of arm bodies 5H'. This metal fitting 5L is part of a mechanism for interlocking the reversing plate 5G and the bag presser 5H.

That is, the lower end of the working rod 5M is pivotally attached to the rear end of the reversing plate 5G in an upright state with a pin.

At the upper end of this rod 5M is an actuating rod 5.
N is consecutively provided. The rod 5N is configured so that the diameters of the large, small, and middle portions are 5N', 5N'', and 5N.
The passive metal fitting 5L is configured to always come into contact with any one of N', 5N'', and 5N.

Therefore, this passive metal fitting 5L is curved in plane at the tip of the rod 5L' fixed to the arm body 5H' so as to be perpendicular to the longitudinal direction of the arm body so as to contact the above-mentioned large, small, and middle portions from the outside. Receiving portions 5L'' are provided in series.

The reason why this receiving part 5L'' is always in contact with the above-mentioned large, small, and middle parts is that the arm body is connected to the spring 5 as described above.
This is because it is being pulled inward by K.

In this case, when the reversing plate is tilted downward by the concave stepped portion 5A of the guide plate 5A, the rod 5M is pushed up, the receiving portion 5L'' is located at the large portion 5N', and as a result, the arm body resists the spring 5K. and move away from the shoot.

Further, when the reversing plate is tilted upward by the convex step portion 5J, the rod 5M is pulled down and the receiving portion 5
L'' is located in the middle part 5N, and in this case as well, the arm body is in a state slightly separated from the chute against the spring force.

Furthermore, when the reversing plate maintains the horizontal state of the plate 5A, the receiving portion 5L'' is the small portion 5.
In this state, the arm body is pressed against the outer peripheral surface of the chute by the spring.

The agitator 7 has an appropriate number of blades 7B planted on the upper and lower surfaces of a horizontal pipe 7A that is rotatably supported.

In this case, a threaded rod 7C is attached to the root of this blade 7b.
Since it is configured to be screwed in and tightened with a nut 7D, the support angle can be adjusted as appropriate by tightening or loosening this nut.

Next, the operation of the present invention will be explained together with its effects.

Inject earth and sand into Hoppa 3 and shoot again on the 5th floor.
A sandbag 8 is placed over the lower end of the outer wall of the sandbag 8 from below, and is held and held against the chute 5F by a bag presser 5H.

In this case, the bag 8 does not fall off because the protrusion 5F' is provided on the bag 8.

On the other hand, the earth and sand in the hopper are removed by the rotating agitator 7.
The liquid is filled into the weighing box 2 while being stirred.

The earth and sand in the weighing box 2 is pushed forward by a pushing device composed of a piston, pushes up the lid 2A, and is discharged.

In this case, the amount of dirt can be adjusted by adjusting the stroke of the piston by operating the limit switch (moving the set position).

The discharged earth and sand falls and fills into the bag 8 via the chute 5F.

Since the chute 5F is attached to the rotary cylinder 5C in a planar radial manner, as the rotary cylinder 5C rotates, the chute 5F sequentially reaches a position below the discharge port 2B and is filled with earth and sand.

As the rotary drum rotates, the bag 8 initially filled with earth and sand is detached and dropped from the chute 5F by the action of the reversing plate 5G and the bag presser 5H.

That is, due to the rotation of the rotary drum, the reversing plate 5G reaches the concave stepped portion 5I and is tilted downward.

At this time, the action rod 5M acts as described above, and the arm body separates outward from the chute (the passive metal fitting 5L is located at the large portion 5N', and the arm body 5H' is moved outward by the distance H'). (move towards).

As a result, the bag 8 filled with earth and sand falls from the reversing plate, so the opening of the bag 8 is tied up.

Next, the process moves on to attaching a new bag 8 to this chute 5F.

Therefore, when the rotary cylinder rotates further, the reversing plate 5G
reaches a convex stepped portion 5J, which causes it to be in an upwardly inclined state. As a result, the rod 5M is pulled down, the passive fitting 5L is located in the middle portion 5N, and the arm body 5H' is moved outward by the distance H.

In this case as well, since there is a gap between the bag presser 5H and the chute 5F, the upper end of the bag 8 is placed over the chute 5F from below and then held by the bag presser.

This work of holding the bag holder is done by stepping on the foot plate 5G'', which is connected to the tip of the reversing plate 5G which is tilted upward by the convex stepped portion 5J, with your toe, and the passive metal fitting 5L is moved to a small position. Located in part 5N'',
The distance between the arm bodies 5H' is the interval H''.At this time,
The bag holder and the chute are in close contact with each other, and the bag 8 is securely held.

The rotary cylinder rotates little by little, moves sequentially toward the discharge port, and repeats the above-mentioned action. The rotation of these rotary cylinders is automatically 1/6 rotation by the operation of the geared motor, and at the 2/6 rotation position, the bag is removed by the operation of the reversing plate, rod, bag holder, etc., which can be called a forced drop mechanism. Sandbags can be manufactured by manually tying the bag opening.

The drive system of the present application is entirely electric, and its power source is an on-board motor generator 9, and two types of electric equipment, a geared motor 10 and a power cylinder 11, are employed.

The operation method is concentrated on the operation panel 12,
It is configured to be actuated by levers and pushbuttons.

Further, the traveling device is equipped with an automobile drive mechanism 13, and is configured to transmit power to the tires via a sprocket and roller chain so that it can be moved a short distance depending on the site conditions.

In addition, the hopper 3 has front and rear inclined surfaces 3A, 3B which are perpendicular to the forward and backward direction of the extrusion device 4, and left and right inclined surfaces 3A and 3B which are perpendicular to the forward and backward directions of the extrusion device 4.
C and 3D are configured in the shape of an inverted truncated pyramid, and
Since the left and right inclined surfaces 3C and 3D are configured to be variable, the following effects can be expected.

Even when the amount of earth and sand in the hopper is small, changing the angle of the slope can make it easier for the earth and sand to slide down.

Furthermore, since the blades 7B of the agitator 7 are configured so that the support angle can be adjusted as appropriate, the following effects can be expected.

The rotational load on the agitator can be reduced,
Even soil with relatively high viscosity can be stirred.
