ものである。 BACKGROUND ART Conventionally, when fresh concrete is pumped from a mixer truck to a required location at a construction site, etc., a pressure pump is used as shown in FIG. That is, a cylinder 4 in which a piston 3 reciprocated by a hydraulic cylinder 2 is installed is provided below the hopper 1, and a suction port 5 and a discharge port 6 of the cylinder 4 are provided.
Valve devices 7 and 8 are attached to each of the valve devices, and the valve devices 7 and 8 are caused to perform opening and closing operations in opposition to each other, and the piston 3 is caused to reciprocate in relation to the opening and closing operations. In this case, when the valve device 7 is opened, the piston 3 is operated so that the ready-mixed concrete put into the hopper 1 can be sucked into the cylinder 4, and when the valve device 8 is opened, the piston 3 is operated so that the ready-mixed concrete in the cylinder 4 can be pumped. 3.

問題を有していた。 However, in order to open and close each valve device 7, 8,
Since it is necessary to control the valve devices 7 and 8 in a time-related manner, the opening/closing mechanism becomes complicated, and the overall size of the device increases accordingly. This resulted in an increase in the complexity of the mechanism. For this reason, it is not easy to attach a large pressure pump as mentioned above to the mixer truck, and therefore, a separately prepared pressure pump truck is usually used to force the fresh concrete from the mixer truck to the required location. This is the actual situation, and it has various problems such as not only being labor intensive and having poor workability, but also high cost.

ツチ38,39を取付ける取付板である。 As shown in FIG. 4, the drive control device for the hydraulic cylinders 23 and 25 drives an oil pump P by the rotational drive of a motor M to pump out oil in an oil tank 26, and pumps oil out of an oil tank 26 via an electromagnetic valve 27. Pressure oil is supplied to the switching valves 28 and 29, and the switching operation of the electromagnetic switching valves 28 and 29 causes the flow control valves 30 to 30 to
33, the respective hydraulic cylinders 23 and 25 are driven to reciprocate the inner cylinder 12 and piston 17. The pressure control valve 27 is a stop valve 34.
A pressure gauge 35 attached to the oil passage is used to set a predetermined pressure necessary to drive the hydraulic cylinders 23, 25. Also, the flow rate control valve 30
33 are for setting the reciprocating speed of the inner cylinder 12 and the piston 17 and maintaining the same speed.
As described above, in order to reciprocate the inner cylinder 12 and piston 17, the direction of oil flow is switched by the electromagnetic switching valves 28 and 29.
The switching operation is achieved by attaching operating rods 36 and 37 to the inner cylinder 12 and the piston rod 24, respectively, and on the other hand, a pair of micro switches 38 to 41 that operate in contact with the operating rods 36 and 37 are connected to the inner cylinder 12 and the piston 17, respectively. The micro switches 38 to 41 are arranged at the same intervals as the travel strokes L and L', and when the operating rods 36 and 37 come into contact with each micro switch 38 to 41, the micro switches 38 to 41 operate, and the relay circuit is activated. It is now being done through By the way, when controlling the electromagnetic switching valves 28 and 29, it is of course possible to use a timer circuit to control the time without using the micro switches 38 to 41 as described above. The electromagnetic switching valves 28 and 29 are connected to respective hydraulic cylinders 23 and 25.
The oil used for driving is recovered into the oil tank 26, and a portion of the oil from the pressure control valve 27 is also recovered into the oil tank 26. Furthermore, the pressure control valve 27 and each flow control valve 30
A manual on-off valve 42 is inserted between the cylinder 11 and the cylinder 11.
Operate this in advance to open the inner cylinder 12 and piston 17.
to a predetermined position (the right end position in FIG. 2). In addition, in Figure 4, 43
Reference numeral 44 indicates a support base on which the present device is mounted, and 44 a mounting plate on which the micro switches 38 and 39 are mounted.

This is then fitted onto the mixer truck frame, etc., and fixed with bolts. In this case, the engine of the mixer truck is used as power to drive the oil pump P via a driving shaft.

動行程が行われる。 As shown in FIGS. 2 and 3, the cylinder 11 and the inner cylinder 12 are respectively provided with suction ports 13, 14 and discharge ports 15, 16 at appropriate intervals in the axial direction. With the reciprocation of the piston 17 fitted into the cylinder, the inner cylinder 12 is reciprocated, and when the suction ports 13 and 14 open and communicate with each other, fresh concrete is sucked into the cylinder 11, and the fresh concrete is sucked into the cylinder 11.
Fresh concrete is discharged from the inside of the cylinder 11 when the cylinder 6 opens and communicates with the cylinder 11. That is, from when the suction ports 13 and 14 are in open communication and the discharge ports 15 and 16 are closed as shown in FIG. 12 in the opposite direction to start sucking fresh concrete into the inner cylinder 12. At the end of the suction stroke, as shown in FIG. 3b, when the inner cylinder 12 reaches 1/2 of the travel stroke L, each suction port 1
3 and 14 are occluded. In this case, the piston 17 reaches the limit point from 1/2 of the travel stroke L' and ends suction. Next, as shown in FIG. 3c, the inner cylinder 12 slides in the same direction toward the limit of the travel stroke L, and the piston 1
7 slides in the opposite direction until it reaches 1/2 of the moving stroke L', the discharge ports 15 and 16 open and communicate with each other as shown in FIG. 3d, and the discharge stroke begins. In this discharge stroke, the inner cylinder 12 slides in the opposite direction until it reaches 1/2 from the limit point of the travel stroke L, and the piston 17
slides in the same direction as described above from 1/2 of the moving stroke L' until reaching the limit point, and when each discharge port 15, 16 is closed, the discharge stroke ends. After the discharge stroke is completed, a moving stroke is performed to open and communicate the suction ports 13 and 14 from the position shown in FIG. 3e to the position shown in FIG. 3a.

Cylinder 1
Stop the movement of piston 2, and in this state piston 1
The suction stroke and the discharge stroke may be performed by the suction and compression operations in step 7.

従来の如きものに比し、小型化し得る。 As described above, according to the fluid pressure feeding device according to the present invention, the suction port and the discharge port can be opened and closed simply by reciprocating the inner cylinder, and the piston is connected to the opening and closing operation of the suction port and the discharge port. Because it only needs to be reciprocated, the structure of the drive control mechanism is simple and compact, and it can be attached to the rear of the mixer truck as is, and the mixer truck itself does not become larger, making it easier to use than conventional The present invention is convenient in that there is no need to provide a pressure pump car in addition to the mixer car, and even if it is used as a pressure pump car, it can be made smaller compared to conventional ones.

い等使用上頗る便利である。 In other words, the inner cylinder reciprocates inside the cylinder, and the piston reciprocates inside the inner cylinder, and the inner cylinder opens and closes only by aligning at least the suction port or discharge port of the inner cylinder with the suction port or discharge port of the cylinder. It suffices to move as a valve, so it can be extremely miniaturized, and moreover, it can directly suck fluid into the inner cylinder from the outside and forcefully feed it from the inner cylinder to the outside, and the suction and discharge lines have large diameters. Furthermore, because the flow resistance is low, it is possible to pump not only liquids such as water, but also concrete containing large-diameter aggregates, oil materials containing slang, etc., and in combination with its ultra-compact size, it can be used as a concrete pump. It can be installed on a mixer truck without any modification, and when used as a pump for fluids containing granular materials such as concrete pumps, it can be easily washed by sucking in and discharging water, and it is also ultra-compact. Regardless, a large amount of suction or discharge can be obtained in one stroke, approximately corresponding to the contents of the inner cylinder, and the pumping pressure is also high, making it very convenient to use.
