摘要： PROBLEM TO BE SOLVED: To restrain occurrence of running-out of a cargo for a hopper by restraining lowering of a level of the hopper by correcting target digging quantity in accordance with a detection value of a picking efficiency detection means so that the target digging quantity by a digging part becomes more than target picking quantity of a fixed quantity picking part. SOLUTION: Picking quantity to be detected by a belt feeder 13 is input to a digging quantity correction part 41, a picking quantity actual value of computed by counting the picking quantity for a specified period of time, and a correction factor is set from a ratio of the picking quantity actual value and the target picking quantity on a control device 40. This correction factor and the target picking quantity are multiplied by a computing element 42, and its result is input to a target torque conversion part 43 as a target digging quantity correction value. The target digging quantity correction value is converted to target torque at the target torque conversion part 43, and it is output to a driving control part 45. Rotating speed of a sprocket and moving speed of a digging part is controlled by the driving control part 45 by driving it in accordance with a control logic so that the target torque and actual driving toque coincide with each other.

摘要： PROBLEM TO BE SOLVED: To provide sufficient strength for receiving digging resistance which acts on a bucket and facilitate the mounting of the bucket. SOLUTION: A platelike bracket 24 is fixed on a chain 12, and a flange 30 of a bucket 9 comes into contact with the bracket 24 from sideways. A stepped part 31 which opposes to an upper end face of the flange 30 in the vertical direction is formed in-the bracket 24. A lock pin 32 is driven and tightened by using an axis of a pin hole on the bracket 24 side and an axis of a pin hole on the flange side as the same axis in a condition in which the flange 30 comes into contact with a joint face of the bracket 24. Furthermore, the bracket 24 and the flange 30 are tightened by a tightening bolt.

摘要： PURPOSE: To improve efficiency in cargo handling work by providing a support member to support a scraper so as to be turnable in the turntable width direction and an actuator to turn the scraper. CONSTITUTION: A scratching-off part arranged in a lower end part of a bucket elevator 5 is inserted into a hold, and for example, when the scratching-off part is set in the anticlockwise direction, an actuator is driven, and a scraper 20 is turned in the width direction of a turntable 15, and is set in an illustrated posture. While slowly rotating the bucket elevator 5 in the anticlockwise direction, a cargo in a hold is excavated and scratched off in order by a chain bucket 10, and is rotated above an elevator 5, and the cargo is discharged. The discharged cargo is loaded on the turntable 15 through a discharge chute 13, and is scratched off by the scraper 20, and is sent to the feeder chute 18 side. On the other hand, when the scratching-off part is set in the clockwise direction, the scraper 20 is turned, and a surface turning in the opposited direction of the cargo carrying direction of the turntable 15 is turned to the feeder chute 18 side.

摘要： PURPOSE: To provide a carrying in/out device which enables the carrying in/out of a heavy weight such as a bulldozer between on the ground and inside a hold by with little labour and in a short time by a continuous unloader. CONSTITUTION: This device is composed of left/right two heavy weight hanging ropes 11 whose base ends are connected to the proper place of the raking part 5 of a continuous unloader UL, a pair of left/right seizing ropes 17 whose lower ends are connected freely to the tip ends of the left/right two heavy goods having ropes 11 and a pair of left/right winding machines 13 to which the upper end of the seizing rope 17 is connected and which is wound up and payed out freely and arranged on the adequate installation floor 8 of a bucket elevator. As the heavy weight hanging rope 11 is always provided on the unloader UL, a labour for carrying ropes and hanging tools is saved and as the heavy weight hanging rope is also descended onto the ground when the seizing rope 17 is lowered by the winding machine, a roping work is facilitated. As bulldozer is hung up by a four points support, stable carrying in/out can be carried out.

摘要： PURPOSE: To facilitate play back operation by correcting a teaching locus following to a correction indication based on a singular point by a singular point setting means, making out a play back locus and controlling so as to follow to the play back locus corrected the drive of a dig out part. CONSTITUTION: An operator sets a singular point by a singular point setting means on the corner part of a holds 17 during a teaching operation. At the time of a play back operation, the operator indicates the correction of a play back locus by a correction indication means. A controller corrects the teaching locus following to a correction indication and makes out the play back locus and the drive of a dig out part 15 is followed to the play back locus corrected in response to the singular point. The teaching locus is obtained as usual by a manual teaching operation. The play back locus is obtained by refering this teaching locus and the dig out part 15 is driven by following to the play back locus and the load 18 in bulk in the hold 17 is dug out and landed.

摘要： PURPOSE:To accurately find durability and prevent trouble such as breakage by constituting the method so that stress value of an apron link at working is compared with a calculated stress value to inspect durability of the apron link. CONSTITUTION:Stress applied on an apron link 1 at working is measured with a strain gauge stuck on the apron link 1. Simultaneously, weight of bulk material held with a bucket 2 is measured. As the measuring means, current value of a motor driving the bucket 2 and the like is considered, and stress applied on the apron link 1 is calculated based on the weight. The stress value of the apron link 1 at working is compared with the calculated stress value, when the actual stress value is under the calculated stress value, the apron link 1 is judged to have durability, and when the actual stress value is over the calculated stress value, it is judged necessary to be repaired.
