Unloading device

Abstract

The invention discloses a discharging device. The discharging device comprises a lifting ring at the top end, at least two suspending ropes connected with the lifting ring, a lifting frame transversely connected to the bottom ends of the at least two suspending ropes, a supporting rope, a pulling rope and a carrying hopper suspended below the lifting frame. A hydraulic system and a hydraulic control system are arranged in the lifting frame. The hydraulic system comprises a hydraulic cylinder and an energy storage device. The hydraulic control system controls circulation of hydraulic oil between the hydraulic cylinder and the energy storage device. The hydraulic cylinder comprises a cylinder body and a piston rod. The piston rod comprises a first end located in the cylinder body and a second end located outside the cylinder body. One of the piston rod and the cylinder body can move in the circulating process of the hydraulic oil, and the other one of the piston rod and the cylinder body is kept fixed in the circulating process of the hydraulic oil. One end of the carrying hopper is connected to the lower portion of the lifting frame through the supporting rope, and the other end of the carrying hopper is connected with the one, capable of moving, of the piston rod and the cylinder body through the pulling rope. The discharging device is easy to operate, and loading and unloading of large-block-type materials are achieved.

Description

technical field [0001] The invention relates to a material unloading device, in particular to a wireless remote control unloading device suitable for bulk material loading and unloading. Background technique [0002] In today's known technology, the loading and unloading of bulk bulk materials usually adopts relatively mature special appliances or equipment such as net bags, grab buckets, loaders, and excavators. However, there is still a lack of suitable and efficient loading and unloading equipment for some bulky materials such as rocks, concrete fragments, etc. that are large in size, different in size and irregular in shape. [0003] In the construction of reclamation and riprap projects, according to the existing technology, net bags are mostly used for loading and unloading operations, which require manual hooking, and decoupling on the ground, high safety risks, low operating efficiency, and large loss of net bags; if rope-type multi-lobe grabs or electro-hydraulic D...

However, there is still a lack of suitable and efficient loading and unloading tools for some bulky materials such as rocks and concrete fragments that are large in size, different in size and irregular in shape.

[0003] In the construction of reclamation and riprap projects, according to the existing technology, net bags are mostly used for loading and unloading operations, which require manual hooking, and decoupling on the ground, high safety risks, low operating efficiency, and large loss of net bags; if rope-type multi-lobe grabs or electro-hydraulic Due to the different sizes and shapes of the materials and the structural reasons of the grab bucket, the operation of multi-flap grabs often leads to the situation that the grasping is not tight, the grip is not solid, and the grip cannot be carried. effective protection
