An unloading spreader with the function of automatically cutting ton bags

Abstract

An unloading spreader with the function of automatically cutting tons of bags, including a spreader carrier, a connecting piece, a bag hook and a cutting assembly, the carrying frame is provided with a connecting piece for connecting with a driving hook for lifting up to The bag hooks of two ton bags, and two cutting assemblies capable of cutting open ton bags; the connectors are connected to the hoisting equipment of the vehicle through steel wire ropes; the two cutting assemblies are correspondingly located at both ends of the carrier, and the cutting The assembly includes a driving mechanism, a mounting rod and a cutter mechanism, the driving mechanism is correspondingly installed on the top surface of the carrier, and the driving mechanism can rotate in a horizontal plane; the power output end of the driving mechanism is connected to the tail end of the mounting rod correspondingly, and The driving mechanism can drive the installation rod to rotate in the vertical plane, and the head end of the installation rod is provided with a cutter mechanism for cutting ton bags; and the spreader can improve the unloading efficiency, reduce the labor cost of unloading and protect workers healthy.

Description

technical field [0001] The invention relates to the technical field of crane spreaders, in particular to an unloading spreader with the function of automatically cutting ton bags. Background technique [0002] As is known, in industries such as metallurgy, chemical industry, petroleum, smelting, coal mines, steel mills, docks, ports, etc., mineral powder or other bulk materials are generally transported in ton bags. The material steps are: [0003] In the first step, the workers at the truck hang the tons of bags on the driving hook one by one; [0004] The second step is to drive the car to the material pool or material pit, where the workers will cut the bottom of the ton bag, and then the bag hook will lift the ton bag, and rely on the gravity of the ton bag itself to unload the material into the pit; [0005] In the third step, when the unloading is completed, drive the truck to the empty space, and then the workers here will remove the empty ton bags; [0006] The fo...

Problems solved by technology

[0007] However, the number of workers participating in the unloading step is at least four, which takes up too many human resources, resulting in high labor costs for manual unloading operations; and during unloading operations, only one ton bag can be lifted at a time, resulting in The unloading efficiency is extremely low; in addition, because the ore powder contains a large amount of sulfide and the bulk material contains a large amount of dust, the site environment is extremely poor, which will cause serious harm to the health of workers;

[0008] In addition, Chinese patent (CN202110306306.X) discloses an automatic cutting and unloading device for alloy packaging bags. operation, eliminating the risk of safety accidents such as vehicle injury and lifting injury during the operation of the staff, avoiding the exposure of the staff to dust pollution, and improving the safety assurance capability; On the rib plate, the material in the packaging bag will be unloaded to the rib plate first, and then unloaded from the material leakage hole on the rib plate, and only one packaging bag can be unloaded at a time, so the unloading efficiency of this device is low ;
