[0005]
A water measuring hopper 10 is provided at substantially the same height as the measuring hoppers 6, 7, and 9, and water is measured by the water measuring hopper 10.
[0006]
Further, sand cut out from the sand weighing hopper 6, gravel cut out from the gravel weighing hopper 7, and the cement weighing hopper 9 were cut out by the collecting hopper 11 arranged below the weighing hoppers 6, 7, 9. The cement and the water cut out from the water measuring hopper 10 are collected as necessary and put into a fixed concrete mixer 12 arranged below the collecting hopper 11.
[0007]
Thus, the concrete mixer 12 can produce ready-mixed concrete by kneading the various concrete materials and water with an agitating blade (not shown) inside. The kneading state in the concrete mixer 12 can be confirmed by monitoring the inside of the concrete mixer 12 with the monitoring camera 13 as needed. The bottom of the concrete mixer 12 is opened as indicated by the arrow, and the kneading is performed. The ready-mixed concrete is taken out.
[0008]
However, there is also a batcher plant in which a plurality of tilting mixers are connected to the collective hopper 11.
[0009]
FIG. 5 is a front view of a tilting mixer used in a conventional batcher plant. A plurality of material charging chutes 14 and 15 are branched from the lower portion of the collecting hopper 11 described in FIG. A single damper 16 is provided on the inlet side of the material chutes 14, 15, which can be switched to the material charging chutes 14, 15, and the outlet side of the material charging chutes 14, 15 is individually rotated and inclined downward. The opening portions 20 and 21 of the tiltable mixers 18 and 19 that can be connected are brought into contact with each other.

Then, the material charging chute 15 is closed by the damper 16, and various concrete materials and water are charged from the collecting hopper 11 to the one tilting mixer 18 through the material charging chute 14, and the tilting type as shown by an arrow a. The mixer 18 is rotated to knead various concrete materials and water in the tiltable mixer 18, and after the kneading is completed, the tiltable mixer 18 is rotated and the opening 20 is lowered as shown by an arrow b. The tiltable mixer 18 is tilted so that the ready-mixed concrete mixed in the tiltable mixer 18 is taken out.
[0011]
While kneading by one tilting mixer 18, the damper 16 is rotated so as to close the material charging chute 14, and the other tilting type is switched from the collecting hopper 11 through the material charging chute 15. Various concrete materials and water are put into the mixer 19 and the tiltable mixer 19 is rotated as indicated by an arrow a to knead the various concrete materials and water in the tiltable mixer 19.
[0012]
While the kneading by the tilting mixer 19 is completed, the kneading by the tilting mixer 18 is completed, and the tilting mixer 18 is tilted as described above, and the raw kneaded in the tilting mixer 18 is performed. Work to remove concrete is performed. Then, the attitude of the tiltable mixer 18 is returned to the original position, and the damper 16 is rotated so as to close the material charging chute 15, and various concrete materials and water are charged into the tiltable mixer 18.
[0013]
The ready-mixed concrete of the one tiltable mixer 18 is taken out, and the kneading in the other tiltable mixer 19 is completed while the concrete material and water are being charged into the tiltable mixer 18 again. As shown by b, the tiltable mixer 19 is tilted so that the opening 21 faces downward, and the work of taking out the ready-mixed concrete in the tiltable mixer 19 is performed.
[0014]
In this way, the plurality of tilting mixers 18 and 19 can alternately perform material charging, kneading, and taking out ready-mixed concrete to improve work efficiency.
[0015]
[Problems to be solved by the invention]
Since the concrete mixer 12 shown in FIG. 4 is a fixed type and is kneaded by rotating the stirring blades inside the concrete mixer 12, the kneading state in the concrete mixer 12 is changed by a fixed monitoring camera 13. In the batcher plant using the tiltable mixers 18 and 19 shown in FIG. 5, the tiltable mixers 18 and 19 rotate as indicated by the arrow a and as indicated by the arrow b. Therefore, the tiltable mixers 18 and 19 cannot be monitored with a fixed monitoring camera.
[0016]
For this reason, conventionally, until the ready-mixed concrete is taken out from the tilting mixers 18 and 19, the kneading state cannot be confirmed, and even if a misbatch occurs, it is unclear, and wasteful power and time can be consumed. there were.
[0017]
