Feeding platform emergency stop safety protection device for branch chipper

Abstract

The invention discloses a feeding platform emergency stop safety protection device for a branch chipper. The feeding platform emergency stop safety protection device is characterized in that a protection rod soldering is arranged on a feeding groove of the branch chipper, one end of the protection rod soldering is fixed in the middle of the feeding groove, the other end of the protection rod soldering is connected with one end of a swing arm, the swing arm is arranged at the lower part of the feeding groove, the swing arm is connected with one end of a linkage rod, the linkage rod is horizontally arranged on the lower part of the feeding groove through two shaft sleeves symmetrically arranged in a spaced mode, two positioning sleeves are arranged on the linkage rod and arranged on the sides, away from each other, of the two shaft sleeves in a spaced mode, a first elastic piece and a second elastic piece are arranged between the two sets of positioning sleeves and the shaft sleeves, thefirst elastic piece is closes to the swing arm, an in-place switch is arranged on the position, close to the first elastic piece, of the lower part of the feeding groove, and a contact of the in-place switch makes contact with the inner side of the step of one corresponding positioning sleeve. According to the device, emergency stop of the branch chipper is faster and more sensitive, mistaken touch of the in-place switch is effectively avoided, unnecessary machine emergency stop is avoided, the safety is effectively improved when the branch chipper is used, and the economic efficiency is improved.

Description

technical field [0001] The invention relates to a branch shredder, in particular to an emergency stop safety protection device for a feeding platform of a branch shredder. Background technique [0002] When the branch crusher is working, due to the complexity of the working conditions of the machine, stones, metals, ropes and other non-cuttable debris mixed into the crushing chamber may damage the blades, and the staff may be brought into the crushing chamber by branches, causing casualties, so , The wood chipper is usually equipped with a safety protection device that can make the machine stop suddenly. [0003] The emergency stop protection device is located in the feeding part of the chipper. The existing emergency stop protection device usually includes protection rods, linkage rods, elastic parts, swing arms, in-position switches and other components. The protection rods are wound from the upper left side of the feeding slot to the right. The lower side is a rod-shaped...

Problems solved by technology

[0004] However, due to the large span of the protective rod at the feeding port of the chipper, it is difficult to realize emergency stop in actual conditions and the sensitivity is low. Risks, resulting in unnecessary losses. In addition, due to the violent jumping of the branches during the crushing process, this kind of jumping is a normal and inevitable vibration, which will lead to distortion of the information collected by the in-position switch. Cause the in-position switch to transmit wrong signal, lead to abnormal emergency stop, high risk of potential safety hazard
