Description

  The present invention is, for example, suitably fed with a stirring device, or suitably shredded with a crushing device as appropriate (for example, greening soil that has been agitated by adding fertilizer and seeds to the soil, Compost, concrete, mortar, finely crushed pieces of wood, etc.) are appropriately stored in the supply mechanism (for example, temporarily stored), and then sent to the transport / compression mechanism. Dissolving via a compression mechanism and an opening / closing mechanism, sending it to an air mixing mechanism, and using a pressure such as air for conveyance to appropriately feed a material to be fed continuously into a suitable conveyance cylinder, The present invention relates to a feeding apparatus and a feeding method for a material to be devised so that the inside of a considerably long conveying cylinder can be smoothly fed to its tip.

Conventionally, as this type of feeding means, for example, a spraying machine as shown in Patent Document 1 has been disclosed.
In this spraying machine, a cylinder that communicates with the hopper and is closed at the front and rear ends is provided under the hopper, and the screw shaft extends from the end of the screw of the screw conveyor provided in the cylinder. Forming an injection cylinder connected to the compressor and a discharge cylinder having an inner diameter larger than the inner diameter of the injection cylinder connected to the spray hose, perpendicular to the conveying direction of the screw conveyor, near the axial end of the extension part, And while opening to the cylinder facing each other, connecting both cylinders with a connecting hose, attaching a loosening wing to the extension near the opening of both cylinders, and between the loosening wing and the end of the screw, into the cylinder, The transported spray material is compressed to form a closed portion that can close the cylinder.

Japanese Patent No. 2729572 (FIG. 1)

However, in the above-described spraying machine, for example, when a spraying material conveyed by a screw conveyor is first compressed to form a closed portion capable of closing the cylinder, the spraying is relatively fluid. In the case of the material, there is a difficulty that it is difficult to provide a closing portion that closes the cylinder because it moves relatively smoothly in the cylinder due to the pushing force of the screw conveyor.
Therefore, if the part where the screw does not exist in the cylinder is formed long, even if it is a spray material having relatively good fluidity, the closed part is surely provided, but the closed part itself is configured to be relatively long. The movement resistance of the closed part in the cylinder is larger than the pushing force of the screw conveyor, and the closed part cannot be moved by the pushing force of the screw conveyor, and the cylinder is clogged. There was a problem that would become. That is, not only does the conveyance of the spray material stop, but there is a problem that the feeding cannot be resumed unless the portion of the spray material clogged in the cylinder is once solved.
Moreover, since the movement resistance force of the closed portion in the cylinder increases instantaneously, it is necessary to set the closed portion so that it does not become clogged in the cylinder (for example, setting the fluidity of the spray material or And setting the length of the part where no screw is present in the cylinder), there were also very difficult points.
In addition, since the loosening wing is attached to the extension part from which the screw shaft is extended, the loosening wing will rotate with the screw that rotates at a relatively low speed, and it is difficult to sufficiently solve the compressed spraying material. There were also problems that took time to solve. Furthermore, maintenance and the like were troublesome.
In addition, since the inner diameter of the cylinder of the part where the loosening wing is provided and the part where the blowing material is compressed is the same, when the compressed blowing material is solved with the loosening blade, Since the entire volume increases rapidly, there is a problem that the spraying material is difficult to unwind smoothly unless the volume of the portion where the loosening blades are provided is sufficiently large.
Further, when the spray material is sent from the hopper into the cylinder of the screw conveyor, for example, if the spray material is relatively light, it is difficult to smoothly feed the material into the cylinder.

Attached to the air mixing casing 40 so as to be rotatable forward and backward, and an upper portion thereof is opened. A pair of left and right support shafts 21 protruding above the air mixing casing 40 and a pair of left and right support shafts 21 are connected. When a predetermined compression force is applied from the rotary actuator 35 and the material to be fed that is compressed at the tip of the conveyance / compression casing 10, the closed state by the pair of left and right presser plates 20 is released, and a pair of left and right presser plates The structure provided with the closure cancellation | release means to which 20 opened was sufficient. That is, you may comprise so that a pair of left-right holding plate 20 can be opened and closed arbitrarily by the action | operation of the rotary actuator 35 (refer FIGS. 4-10).

  For example, a pressure-sensitive sensor 30 provided on one presser plate 20 is used as the closing release means when the rotary actuator 35 is used. For example, the pressure sensor 30 is provided with a hole in a part of the pressing plate 20, and an elastic sheet material 31 serving as a diaphragm is bonded so as to close the inside of the hole. A spring 32 and a switch 33 are arranged (see FIG. 12). That is, when the material to be fed pressed and compressed in the conveyance / compression casing 10 is about to move the tip, the predetermined pressing force presses the elastic sheet material 31 against the spring 32, and the switch The rotary actuator 35 is actuated when it contacts 33, and the pair of left and right presser plates 20 are opened (or the force that closed the pair of left and right presser plates 20 is released).

  Further, the opening / closing mechanism C shown in FIGS. 15 to 18 includes, for example, one presser plate 20 that swings in the vertical direction to open and close part or all of the front end opening of the conveyance / compression casing 10 and the presser.

When a predetermined force is applied to the stopper 25 (for example, a force that causes the material to be fed, which has been pressed and fixed at the front end portion of the conveyance / compression casing 10, to press the presser plate 20 and swings the presser plate 20 upward. Or a load applied to move the tip of the lever 22 downward), the stopper 25 pushes back the locking projection 26 against the resilient force of the resilient spring 27, and the stopper 25 and the locking projection 26 The locked state is one that was configured to be automatically released. That is, when the feed object compressed in the transport / compression casing 10 is about to move toward the trap, the closing release means is automatically activated when a predetermined pressing force is applied to the presser plate 20. The presser plate 20 is operated to open (or the force that has closed the presser plate 20 is released).
