The operation of the concrete pouring device 10 thus configured will be described. First, the storage hopper
When the concrete 11 is thrown in through the opening 22 of 21, the stored weight measuring means 30 measures the stored weight of the concrete 11 stored inside the storage hopper 21, and outputs a stored weight signal to the signal converter 151. . Then, the rotation shaft of the motor 41 of the fixed amount discharge means 40 is driven, whereby the storage hopper is
The conveyor shaft 42 provided in the lower part of the inside 21 rotates, and the spiral part 43 attached around it rotates.
As a result, the block of concrete 11 inside the storage hopper 21 moves to the inlet of the discharge port 23 at the left end. On this occasion,
The concrete 11 hardly moves in the circumferential direction of the conveyor shaft 42 but mainly in the axial direction due to the weight of the concrete 11 itself.

Further, as the conveyor shaft 42 rotates, the rotary blades 51 also rotate, and the lumps of concrete 11 that have continuously moved in the axial direction of the conveyor shaft 42 are rotated by the rotary blades.
51 split. As a result, a large lump of concrete 11 can be divided and crushed. Although the discharging direction of the crushed concrete 11 can be changed by changing the inclination angle θ of the rotary blade 51, specifically, the inclination angle θ is set to 30 to 60 degrees.

On the other hand, the rotation speed of the conveyor shaft 42 is detected by a rotation speed detector 45 attached to the other end, and this rotation speed detector 45 converts the rotation speed detection signal into a signal converter.
Output to 152. Next, the concrete 11 that has been divided and crushed is put into the vibrating subdivision machine 60 from the outlet 23. In the vibration subdivision machine 60, when the motor 77 rotates, the disc 76 connected to the rotation shaft of the motor 77 rotates, and the swing bar 69 rotatably attached to the peripheral edge of the disc 76. One end of the body makes a rotational movement. Since the other end of the swing bar 69 is rotatably connected to the shaft 72 of the right link 68 and the center link 67, the rotary motion about the rotary disk 76 at one end of the swing bar 69 is performed. The other end of the rocking bar 69 is converted into a reciprocating motion that reciprocates left and right on a circumference centered on the shaft 73 and having a radius of the length of the right link 68. Further, this reciprocating movement causes the central link 67 to move in parallel to the left and right and up and down by the parallel movement mechanism, so that the main body 62 fixed to the center of the center link 67 vibrates up and down and left and right. As a result, the lumps of concrete 11 put into the vibrating subdivision machine 60 are arranged at predetermined intervals from the first to the first.
3 parallel bars 63-65 left / right and up / down vibration, and each parallel bar 63-65
It is further crushed and subdivided by the drop impact when it falls on the top.

Further, the vibration subdivision machine 60 is operated in accordance with the change in the discharge amount from the fixed amount discharge means 40. That is,
The rotation speed of the conveyor shaft 42 is detected by the rotation speed detector 45, and the rotation speed detection signal is output to the computing unit 156 via the signal converter 152. In this calculator 156, when the rotation speed detection signal is input, the discharge amount of the concrete 11 discharged from the fixed amount discharge means 40 is obtained, and the rotation speed of the motor 77 of the vibration subdivision machine 60 corresponding to this discharge amount is calculated. It is calculated in the container 156. Then, the rotation speed operation signal is sent to the control panel 155 and displayed, and at the same time, the rotation speed operation signal is sent from the control board 155 to the motor 77 of the vibration subdivision machine 60.

As a result, the vibration subdivision machine 60 can be operated by the vibration corresponding to the change in the flow rate of the concrete 11, and the grinding efficiency can be improved. Next, as shown in FIG. 1, the fragmented concrete 11 is thrown into a throwing duct 78 arranged below the vibrating subdivision machine 60. The concrete 11 is guided by the charging duct 78 and the two plates 9 of the direction changing means 90 provided below the charging duct 78.
It is thrown into the throwing passage 103 between 7,98. These two plates 97,
When the concrete 11 is put near the center in the longitudinal direction of the form 120, both are positioned in the vertical direction, and when the concrete 11 is put into both ends of the form 120, the inside of the end frame 113 is shown. Tilte one side so that concrete 11 can be poured. That is, as shown in FIG. 1, when the direction changing means 90 is located at the left end of the mold 120, the direction changing means 90
The motor 92 on the right side of is rotated counterclockwise, and the lever 94 connected to the rotation shaft of the motor 92 is rotated counterclockwise by a predetermined angle. As a result, the gear 96 meshing with the tooth profile formed around the lever 94 also rotates right by a predetermined angle, and the right side plate 98 connected to the shaft of the gear 96 also rotates right by a predetermined angle and tilts. On the other hand, when the direction changing means 90 is located at the right end of the mold 120, the left side plate 97 is rotated counterclockwise by a predetermined angle and tilted. As a result, at both ends 125, 125 of the form 120,
The concrete 11 can be dropped diagonally toward the inner wall side surface, and at the intermediate portion 124 of the form 120, the concrete 11 can be dropped vertically. Therefore, the formwork
Concrete 11 can also be put inside the end frame 113 arranged so as to cover both ends 125, 125 of the 120.

The inclination angles of the plates 97 and 98 are specifically set to 60 degrees or less from the vertical. If the inclination angle of the plates 97 and 98 exceeds 60 degrees, concrete 1 will be placed on the plates 97 and 98.
This is because 1 is easily deposited. The direction changing means 90
The plates 97, 98 are adjusted in proper directions in accordance with the movement position of the carriage 134. That is, the position detection signal output from the position detection means 140 is passed through the signal converter 154 to the calculator 156.
Entered in. When the position detection signal is input, the calculator 156
Calculates the proper angle of the plates 97, 98 corresponding to the movement position of the carriage 134, and the rotation speed of the motors 91, 92 for making the plates 97, 98 an appropriate angle is calculated by the calculator 156, and the rotation speed operation is performed. The signal is sent to the control board 155. Then, from this control panel 155, a rotation speed operation signal is sent to the motors 91, 92 of the direction changing means 90. Thereby, the plates 97, 9 of the direction changing means 90 are
8 is tilted at an angle corresponding to the moving position of the carriage 134,
Even at both ends of 120, concrete 11 can be uniformly filled without forming a cavity or the like of concrete 11.

Further, the surfaces of the plates 97 and 98 facing each other have an inverted V-shape and are perpendicular to the surfaces of the diaphragm guides 99 and 100, and an insertion passage 103 formed by the diaphragm guides 99 and 100.
Therefore, the introduction of the concrete 11 introduced into the form 120 is guided by the drawing guides 99, 100, and the plates 97,
Concentrate on the input passage 103 near the center in the width direction of 98. Therefore, the uncured concrete 11 does not accumulate between the scattering prevention guides 123 on both sides of the form 120 and the periphery of the reinforcing bar cage 110. This allows concrete 1 along hoop lines 111
1 does not build up in a bridge shape from both sides, it is possible to prevent the formation of cavities inside the reinforcing steel basket 110, and to uniformly fill the uncured concrete 11 inside the form 120. You can

On the other hand, the concrete 11 has a direction changing means 90.
It is put into the form 120 placed on the dolly 134 via, and at this time, the form 120 moves at an appropriate speed. That is, the rotation shaft of the motor 131 arranged at the lower portion of the carriage 134 rotates, and the wheels 133 connected thereto also rotate, moving the carriage 134 along the rails 135, 135. At this time, the rotation speed of the motor 131 is detected by the rotation speed detector 132, and the rotation speed detection signal is sent to the signal converter 153.

Further, the position detecting means 1 is provided below the carriage 134.
Since 40 is provided, the position of the carriage 134 can be detected, and the position detection signal is sent to the signal converter 154. On the other hand, the stored weight signal from the stored weight measuring means 30 input to each of the signal converters 151 to 154, the rotation speed detection signal from the fixed amount discharge means 40 and the moving means 130, and the position detection signal from the position detection means 140 From the signal converters 151 to 154 to the calculator 15
Dispatched to 6. In this computing unit 156, first, by inputting the stored weight signal from the signal converter 151 and the position detection signal from the signal converter 154, the input weight of the concrete 11 to the mold 120 and the mold 120 The relationship with the moving position is calculated. Next, the calculator 156 compares the input weight of the concrete 11 with a preset appropriate input weight of the concrete 11. As a result, if it is out of the proper input weight, the wheel 133 has an appropriate rotation speed of the conveyor shaft 42 of the constant amount discharging means 40 or an appropriate moving speed of the moving means 130 so as to obtain an appropriate input weight. Of at least one of the rotation speeds of the respective motors is transmitted to the control panel 155 as respective rotation speed operation signals, and the rotation speed operation signals are transmitted from the control board 155 to the respective motors 41, 77, 92, 131. To be done.

That is, when the weight of the concrete 11 charged into the form 120 is less than the proper weight, the number of revolutions of the conveyor shaft 42 of the constant amount discharge means 40 per unit time is increased to increase the discharge amount, or , Means of transportation 130
