Problems solved by technology

[0010] The invention proposes a retractable storage yard self-adaptive flexible bucket wheel device, which solves the problem that the bucket wheel and the ground are rigidly collided and cannot carry out the storage yard cleaning operation. While ensuring the normal material retrieving function of the bucket wheel machine, it also has the cleaning operation function

Embodiment 1

[0050] In the first embodiment, during the normal reclaiming and material lifting process of the hopper 8, the digging resistance, material gravity and the self-weight of the hopper 8 acting on the hopper 8 are borne by the hopper outer limit baffle 27 of the bucket wheel body 7, and the spring pressing rod 37 In the initial state, the hopper 8 is in a rigidly open state without being subjected to tension and pressure; during the unloading and no-load operation of the hopper 8, the spring pressure rod 37 is pressed by the gravity of the hopper 8, and the cylindrical spring retracting device 9 The initial pre-pressure is greater than the pressure of the spring pressing rod 37 under the action of the self-weight of the hopper 8, the self-weight of the hopper 8 cannot push the spring pressing rod 37 to move in the axial direction, the cylindrical spring 35 is still in the pre-compressed state, and the spring pressing rod 37 is always in the initial state , the hopper 8 is in a sem...

Embodiment 2

[0054] In the second embodiment, during the normal reclaiming and material lifting process of the hopper 8, the digging resistance, material gravity and the self-weight of the hopper 8 acting on the hopper 8 are borne by the hopper outer limit baffle 27 of the bucket wheel body 7. At this time, the plate The spring retracting device 10 is in the initial state and does not bear tension and pressure, and the hopper 8 is in a rigidly open state; during the unloading and no-load operation of the hopper 8, the head of the leaf spring retracting device 10 is under the action of the gravity of the hopper 8. Under pressure, the initial pre-pressure of the leaf spring retracting device 10 is greater than the pressure generated by the leaf spring retracting device 10 under the action of the self-weight of the hopper 8, and the self-weight of the hopper 8 cannot compress the leaf spring retracting device 10 to move inward, and the leaf spring returns The retracting device 10 is in the ini...

Embodiment 3

[0057] In the third embodiment, the bucket wheel body 7 is the same as the bucket wheel body 7 in the first embodiment.

[0058] In the third embodiment, during the normal reclaiming and material lifting process of the hopper 8, the digging resistance, material gravity and the self-weight of the hopper 8 acting on the hopper 8 are borne by the hopper outer limit baffle 27 of the bucket wheel body 7, and the hydraulic pressure rod 40 In the initial state, and does not bear tension and pressure, the hopper 8 is in a rigidly open state; during the unloading and no-load operation of the hopper 8, the hydraulic pressure rod 40 is pressurized by the gravity of the hopper 8, and the nitrogen in the air bag 37 is pressed. 39 The pressure is greater than the pressure of the hydraulic pressure rod 40 under the action of the self-weight of the hopper 8, the self-weight of the hopper 8 cannot push the hydraulic pressure rod 40 to move in the axial direction, the hydraulic pressure rod 40 i...

Abstract

The invention discloses a retraction type self-adaptation flexible bucket-wheel device of a storage yard. A bucket wheel shaft device is mounted at the end of a cantilever through a dedicated connecting seat, and a flexible bucket wheel is connected with the bucket wheel shaft device through a bolt; hoppers are evenly distributed on the circular ring at the outmost end of a bucket wheel body, and a tail end connecting seat of each hopper is connected with a hopper connecting base of the bucket wheel body through a first pin shaft; a side connecting seat of each hopper is connected with the head of a flexible retraction device through a second pin shaft, and the tail of each flexible retraction device is connected with the bucket wheel body through a flexible retraction connecting device; a middle connecting body of the bucket wheel body is connected with the bucket wheel shaft device through a bolt; and the flexible retraction devices are symmetrically arranged along the left side and the right side of a top cover plate of the bucket wheel body. A bucket wheel stack material taking machine with the flexible bucket wheel has capacity of conducting the normal material taking work and also directly conducting site cleaning work, the site cleaning cost is reduced, and the device can adapt to the terrain of the storage yard, and is safe, reliable and high in adaptability; and the site cleaning work is continuously carried out, and the beneficial effects of being high in efficiency, good in site cleaning effect and the like are achieved.

Description

technical field [0001] The invention relates to construction machinery, in particular to a retractable yard adaptive flexible bucket wheel device. Background technique [0002] With the rapid development of my country's economy, my country's demand for bulk cargoes such as coal and ore has skyrocketed. Every year, a large number of bulk cargoes such as coal, ore and ore are transported to China by large freighters. The port is the first transfer station for these bulk cargoes. The transportation process of bulk cargo from ships to the yard is as follows: ship → ship unloader → belt conveyor → bucket wheel stacker and reclaimer → yard, the bulk cargo is transferred from the yard The conveying process is as follows: yard → bucket wheel stacker and reclaimer → belt conveyor → loading equipment → train carriage, or yard → bucket wheel stacker and reclaimer → belt conveyor → ship loader → ship. Bucket wheel stacker and reclaimer is a continuous stacking and reclaiming equipment ...
