Mower brake make-and-break detection device and detection method thereof

Abstract

The invention discloses a mower brake make-and-break detection device and a detection method thereof. The device comprises a base, a brake support tray is further fixed to the base, a locating pin anda brake pad support step are fixed to the brake support tray, and a telescopic cylinder is further fixed to the brake support tray; a conducting strip of which the left side can be in contact with abrake extinction wire is fixed to the telescopic cylinder, a first wire is further connected to the back of the left side of the conducting strip, a second wire is connected to the brake support tray,a connection hole is further formed in the right side of the conducting strip, an insulation sleeve is fixed in the connection hole, a conductive head for being in contact with a brake block for braking is fixed in the insulation sleeve, a third wire and a fourth wire are connected to the tail of the conductive head, and the first wire and the third wire are connected to a first make-and-break detection device body; the second wire and the fourth wire are connected to a second make-and-break detection device body. The mower brake make-and-break detection device is simple in structure and candetect the make-and-break situation of a brake fast and conveniently, and the detection efficiency is high.

Description

technical field [0001] The invention belongs to the field of lawnmower brakes, and in particular relates to a brake on-off detection device for a lawnmower. Background technique [0002] After the lawn mower is stopped, due to the effect of inertia, the cutter on it will continue to run, so it is necessary to install a lawn mower brake on the lawn mower. The lawn mower brake mainly includes five parts, namely the brake base 19 , flameout line 20, brake arm 21, tension spring 22 and brake block 23, wherein the brake block is connected to the brake arm by screws, and an insulating sheet is clamped between the brake block and the brake arm, as well as between the brake arm and the screw, and the flameout The line is directly connected to the screw. In order to ensure the normal operation of the lawn mower brake, it is necessary to keep the brake block and the flameout line connected (because the brake block, the screw and the flameout line are connected), the brake block and th...

[0002] After the lawn mower is stopped, due to the effect of inertia, the cutter on it will continue to run, so it is necessary to install a lawn mower brake on the lawn mower. The lawn mower brake mainly includes five parts, namely the brake base 19 , flameout line 20, brake arm 21, tension spring 22 and brake block 23, wherein the brake block is connected to the brake arm by screws, and an insulating sheet is clamped between the brake block and the brake arm, as well as between the brake arm and the screw, and the flameout The line is directly connected to the screw. In order to ensure the normal operation of the lawn mower brake, it is necessary to keep the brake block and the flameout line connected (because the brake block, the screw and the flameout line are connected), the brake block and the flameout line are connected. The brake base remains in an open circuit state (because there is an insulating sheet clamped between the brake block and the brake arm), but there is currently no special equipment to detect the on-off state of the lawn mower brake. The current detection method is to directly brake the lawn mower. Assembled on the lawn mower to detect its operating status, so as to judge its on-off, this detection method is inefficient
