Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] Referring to Fig. 1, the chain drop detection mechanism of the material rake device of the paving machine includes a V-shaped detection rod 1, a touch switch 2, and an alarm. The fulcrum 11 of the V-shaped detection rod 1 is hinged on a point seat 3. The seat 3 is fixed on the frame of the material rake device of the paving machine. The detection end 12 of the V-shaped detection rod 1 is close to the material rake chain 5 on the detected optical sprocket 4, and the touch end 13 is in contact with the touch switch 2 to trigger The switch 2 is installed on the frame of the material rake device of the paving machine, and the alarm device is connected with the electric signal of the touch switch 2. The alarm device can be an alarm lamp or a buzzer.

[0012] A torsion spring for resetting the V-shaped detection rod 1 is arranged in the fulcr...

Abstract

The invention discloses a chain dislocating detecting mechanism for claw apparatuses of felting machines, which is characterized in that the invention comprises a V-shaped detecting rod, a touch switch and an alarm equipment, wherein the fulcrum of the V-shaped detecting rod is hinged to a fulcrum seat fixed on the framework of a claw apparatus of a felting machine, the detecting end of the V-shaped detecting rod closes to a claw chain for detecting, the touch end of the V-shaped detecting rod is in contact with the touch switch which is positioned on the framework of a claw apparatus of a felting machine, and the alarm equipment is connected with electrical signals of the touch switch. When the chain dislocates, the claw chain touches the detecting end of the V-shaped detecting rod which then swings, the touch end of the V-shaped detecting rod touches the touch switch which then is communicated with the alarm equipment to send alarming signals, thereby operational workers are warned to tense the claw chain.

Description

technical field [0001] The invention relates to the technical field of a chain transmission mechanism, in particular to a chain drop detection mechanism of a material rake device of a paving machine. Background technique [0002] At present, the chain transmission mechanism of the material rake device of the paving machine generally includes a driving motor, a main sprocket transmission mechanism and a combined movement of the material rake chain driven by the main sprocket transmission mechanism, and the material rake chain combination is usually divided into two groups, each set in The two sides of the frame of the rake device synchronously drive the movement of the rakes connected to the rake chains in the rake chain combination at both ends to realize raking. Since the material rake chain is a long chain, it is impossible to avoid chain drop during operation. Especially after adopting the light sprocket wheel invented by the applicant, the probability of dropping the ch...
