Embodiment Construction

[0013] Such as figure 1 Shown, a kind of ear box lifting safety device, it comprises a frame 1, a lifting support frame 2, an ear box 3, a hydraulic cylinder 4 and a safety bar 5. Wherein, the bottom bolt of the lifting support frame 2 is connected to one end of the frame 1, and the lifting support frame 2 is angular in consideration of the support strength and stability.

[0014] Such as figure 1 As shown, the discharge end of the ear box 3 is hinged on the top of the lifting support frame 2, the piston rod 401 of the hydraulic cylinder 4 is hinged on the ear box 3 through the first hinge seat 6, and the cylinder body 402 of the hydraulic cylinder 4 passes through the second The hinged seat 7 is hinged on the bottom of the lifting support frame 2, and the expansion and contraction of the hydraulic cylinder 4 piston rod 401 drives the ear box 3 to lift or fall around the hinge point.

[0015] exist figure 1 Among them, a fixed plate 8 is provided on the outer box body of th...

Abstract

The invention discloses a cluster box lifting safety device, and solves the problems of inconvenience to dismount a traditional cluster box and a frame safety rod and weak use effect. A lifting support frame is fixedly connected to one end of a frame; one end of a cluster box is hinged to the top of the lifting support frame; a piston rod of a hydraulic cylinder is hinged to the cluster box by a first hinge base; a cylinder body is hinged to the lower part of the lifting support frame by a second hinge base; a box body on the outer side of the cluster box is connected with a fixed base by a fixed plate; a hinge end of a safety lever is hinged to one side of the first hinge base by a third hinge base, and a free end is fixed with a connecting plate; and the connecting plate is pinned to the fixed base by an elastic bolt, or is deviated from the elastic bolt to eject against a cylinder cover of the hydraulic cylinder. The cluster box lifting safety device is reasonable in design, simple in structure and excellent in safety, can pull the elastic bolt to deviate the safety lever from the fixed base, and is convenient to operate and reliable in use.

Description

technical field [0001] The invention relates to a device for unloading objects or materials by tilting an ear box, in particular to a lifting safety device for the ear box. Background technique [0002] As we know, corn harvesters are generally equipped with self-unloading granaries for temporarily storing ears. Its self-unloading granary usually includes an ear box hinged at one end to the frame and a hydraulic cylinder fixed between the frame and the ear box. When unloading the ears, the piston rod of the hydraulic cylinder pushes the ear box to rotate around the hinge point, and the ear box The ear of the ear is dumped and unloaded through the lower end of the ear box. When the corn harvester repairs and maintains the parts near and below the ear box, the ear box needs to be raised, and the ear box is pushed by the drive of the hydraulic cylinder. Maintenance personnel operate under the fruit ear box, once the hydraulic cylinder fails, the fruit ear box falls rapidly un...
