Description

[Detailed description of the invention] <> Industrial application field The present invention relates to a pumping device used for moving earth and sand, and pumping concrete or various powders.

<> Prior Art A piston-type pumping device as shown in FIG. 6 exists as one of the devices for pumping fluids such as fresh concrete, gravel, and various powders.

This piston-type pressure feeding device takes concrete or other material under pressure into cylinder b by opening and closing suction valve c at the bottom of hopper a, and interlocks the opening and closing of discharge valve d at the front of cylinder b and suction valve c. The structure is such that the compressed material is discharged in front of the piston by the reciprocating movement of the piston e inserted into the cylinder b.

A screw conveyor may also be used as a moving device to discharge excavated soil backwards.

<> Problems to be Solved by the Present Invention The above-mentioned pressure feeding devices and moving devices have the following problems.

(a) The object to be transferred is moved by the reciprocating motion of the piston e inside the cylinder.

Therefore, the discharge of the transferred material becomes intermittent, and continuous discharge is impossible.

(b) A valve mechanism is required between the hopper a and the cylinder b, and the structure is complicated, as the suction valve c is interlocked with the discharge valve d.

(c) It requires a cylinder part behind the piston that is longer than the piston's telescopic dimension, so it cannot be used unless there is a large space behind the main body.

(d) Movement of earth and sand by screw conveyor,
Since the entire screw conveyor must be rotated over its entire length, a large power source is required.

The present invention was developed to solve the above-mentioned problems, and is capable of continuous discharge, has a simple mechanism, and allows the user to freely select the direction and position of the transferred object. The purpose is to provide a rotary pumping device.

<> Means for solving the problem In order to achieve the above purpose, the present invention adopted the following means. (Figures 1 and 2) A rotary plate 3 and a push-out plate 22, which are two plates that rotate in the same direction around the axis of the cylinder 1, are installed in a cylinder 1 having an input port 11 and a discharge port 12. do.

The configuration is such that one plate rotates and stops when it passes through the discharge port, and the other plate starts rotating.

The pressurized material A introduced from the input port 11 of the cylinder 1 is successively pushed by two plates, the rotary plate 3 and the extrusion plate 22, and is discharged from the discharge port 12.

<> Example Next, an example of the rotary pumping device of the present invention will be described based on the drawings.

The pumping device of the present invention is composed of a cylinder 1 having an input port 11 and a discharge port 12 on its circumferential surface, a plate-like rotating body 2 rotating inside the cylinder 1, and a rotating plate 3.

(a) Cylinder (Figure 2) The cylinder 1 is a cylinder with both ends open, and an inlet 11 and an outlet 12 are provided at two locations on its circumferential surface, extending over the entire length of the cylinder 1.

(B) Rotating body (FIG. 1) The rotating body 2 is a member in which two discs 21 having the same diameter as the cylinder 1 and facing each other are connected by a rectangular extruded plate 22.

The spacing between the disks 21 is made equal to the total length of the cylinder.

The disc 21 has a shaft hole 23 at its center, and a shaft cylinder 24 having the same diameter as the shaft hole 23 is provided protruding from each shaft hole 23 toward the outside.

The extruded plate 22 is a rectangular plate having a horizontal side 25 equal to the entire length of the cylinder 1 and a vertical side 26 equal to the distance from the shaft hole 23 of the disk 21 to the outer periphery.

Then, it is installed between each disk 21 so that the vertical side 26 is located in the centrifugal direction from the shaft hole 23 of each disk 21.

An eaves portion 27 is provided on the rotation direction side of the tip of the horizontal side 25.
to protrude.

The above-mentioned rotating body 2 is installed inside the cylinder 1 and has a shaft cylinder 24.
It is a member that rotates around the center.

(C) Rotating Plate The rotating plate 3 is a member in which a plate body having a length equal to the vertical side 26 of the extruded plate 22 projects from the shaft rod 31.

The width in the direction of the shaft 31 is the length between the two discs 21 of the rotating body 2.

This rotary plate 3 is a member that rotates within the rotary body 2 by inserting both ends of a shaft rod 31 into the shaft cylinder 24 of the rotary body 2 .

(d) Overall configuration In the pressure feeding device consisting of the above members, the rotating body 2 rotates within the cylinder 1, and the rotating plate 3 inserts both ends of the shaft rod 31 into the two shaft cylinders 24 of the rotating body 2. and configure it to rotate.

The rotating body 2 and rotating plate 3 rotate in the same direction.

Further, the extrusion plate 22 of the rotating body 2 and the rotating plate 3 stop at the point where they pass the discharge port 12 of the cylinder body 1, and when one stops, the other one, which had been stopped at that point, starts rotating. Configure it to do so.

<> Function Next, the operating state of the pressure feeding device of the present invention will be explained.

(a) State before start of operation (FIG. 3) The extrusion plate 22 of the rotating body 2 and the rotating plate 3 are stopped at a point where they pass through the discharge port 12 of the cylindrical body 1, overlapping each other.

Regarding the positional relationship between the push-out plate 22 and the rotary plate 3, either one may be in the front with respect to the rotation direction, but here, the push-out plate 22 is positioned in the front and starts operation.

(b) Feeding of pressurized material and rotation of extrusion plate The pressurized material A is inputted through the input port 11 of the cylinder body 1.

When the charged material A fills the inside of the cylinder 1, the extrusion plate 22 is rotated. (Fig. 4) Since the rotary plate 3 located on the discharge port 12 side from the extrusion plate 22 remains stationary, the pressurized material A filling the inside of the cylinder 1 is pushed by the extrusion plate 22 and moves toward the discharge port 12 side. , comes into contact with the rotating plate 3 that is stopped on the opposite side of the discharge port 12, and is discharged from the discharge port 12.

(c) Rotation of the rotary plate (Fig. 5) The extrusion plate 22 that extruded the pressurized material A is the discharge port 12
When it passes through and comes into contact with the stopped rotating plate 3, the rotating plate 3 starts rotating and the extrusion plate 22 stops.

Even while the extrusion plate 22 is rotating while extruding the pressurized material A, the injection of the pressurized material A from the input port 11 continues, so that the inside of the cylinder 1 is filled with a new compressed material A1.

Then, the new pressurized material A1 is pushed by the rotary plate 3 and extruded from the discharge port 12.

The rotary plate 3 that has extruded the compressed material A1 and passed through the discharge port 12 stops, and the extrusion plate 22 starts rotating.

The extrusion plate 22 and the rotary plate 3 repeat the same operation thereafter to force-feed the material A.

<> Effects of the invention Since the invention is as explained above, the following effects can be expected.

(a) While one of the plates continues to rotate while pushing out the material to be pumped inside the cylinder, the material to be pumped continues to be fed through the input port.

When one plate finishes extruding the material to be compressed and stops at the point where it passes through the discharge port, the other plate starts rotating and starts extruding a new material to be compressed.

By repeating the above operations, it is possible to discharge continuously without interruption.

(b) There is no need for shutters etc. linked to the inlet and outlet ports, and unlike the piston type, there is no need for various equipment such as a cylinder at the rear, so the mechanism and structure are simple.

(c) Since the power is sufficient to give the same rotation to the rotating plate and rotating body inside the cylinder, there is no need for a large amount of power to rotate the entire body like a screw conveyor.

(d) Unlike a screw conveyor, the direction of transport is not fixed, and the position and direction of the discharged material can be freely selected.

Additionally, the overall height of the device is low, allowing it to be used in narrow spaces.

(E) A conventionally known device is one in which two plates are housed, one of which has a rotating shaft located at the center of the cylinder, and the other plate's rotating shaft serving as the opening/closing door of the discharge port. exist.

In such a device, although there are two rotating parts as in the present invention, there is only one plate that actually pushes out the contents.

However, in the device of the present invention, since the center of rotation of the two plates is located at the center of the cylinder, the two plates alternately discharge the contents, and the dispensing operation may be interrupted. There is no.
