Description

Technical Field

[0001] The utility model relates to the field of demolition and recovery, in particular to a hydraulic shear for large-opening recovery. Background Art

[0002] Resource recycling is an important means to achieve sustainable development, and efficient and easy-to-use tools are the key to increasing the feasibility of resource recycling. At present, hydraulic shears are widely used in waste treatment and recycling operations as a commonly used shearing and demolition tool. In the process of shearing materials, the hydraulic shears allow the material to extend between the teeth of the two blades, and then the hydraulic cylinder is started to push the two blades to move toward each other to shear the material. However, the left and right sides of the existing hydraulic shears are single-stage, and the shear body opening size is small. In order to obtain a larger shear opening, it is necessary to lengthen the shear body, which results in the overall size of the hydraulic shears being long, heavy, and energy-consuming, and inconvenient to operate and store.

[0003] For example, patent application CN215746727U discloses a hand-held hydraulic shear, including a hydraulic cylinder, a piston rod is provided on one side of the hydraulic cylinder, an oil sleeve is connected to the top of the hydraulic cylinder, a piston push rod is connected to the telescopic end of the hydraulic cylinder, a groove is provided inside the piston push rod, a movable blade is installed inside the groove, a second opening is provided inside the movable blade, a third opening is provided inside one side of the piston push rod, and a first latch is connected inside the second opening and the third opening. However, the opening of the shear body in this patent application is relatively small. When using the hydraulic shear to shear relatively thick materials, the movable blade and the fixed blade of the hydraulic shear cannot be placed on the surface of the material. It is necessary to loosen the bolts, adjust the telescopic frame to the corresponding height, and tighten the bolts. The operation is complicated, which greatly reduces the working efficiency of the hydraulic shear. Utility Model Content

[0028] The utility model drives the upper and lower shear bodies to open and close through the booster oil cylinder 800 and the hydraulic cylinder assembly 300 to achieve shearing. The shear body is a two-stage type, and the piston rod 310, the upper and lower shear bodies and the connecting rod form a four-bar linkage. Under the same shear body length, the shear opening is larger, the operation efficiency is higher, and it is convenient to operate and store.

[0029] The invention also includes a mounting bracket 200, and the connecting frame 100 is detachably connected to the mounting bracket 200. The large opening recovery hydraulic shear is connected to the mechanical arm through the mounting bracket 200 to achieve position movement.

[0030] The large opening recycling hydraulic shear is a symmetrical structure, and the four-bar linkage is symmetrically arranged on both sides of the connecting frame 100. The utility model is a bilaterally symmetrical structure, which makes the material evenly stressed and the material cut smooth during shearing, further improving the safety of subsequent operations.

[0031] The connecting rod 600 is provided with a first hinge hole 601 and a second hinge hole 602 of the connecting rod. The lower scissor body 400 is hinged to the first hinge hole 601 of the connecting rod through the connecting shaft 700.

At the same time, the hydraulic oil enters the hydraulic cylinder assembly 300 to move the piston rod 310, and drives the upper shear body 500 to move through the connecting shaft 700 to close the upper shear mouth and complete the shearing and crushing operation. The shear body is a two-stage type. Under the same shear body length, the shearing opening is larger and the operation efficiency is higher.
