Embodiment Construction

[0015] Further description will be given below in conjunction with the accompanying drawings

[0016] like figure 2 As shown, this product: the spreader blocking sensor mechanism 9 is installed at the junction of the asphalt spout 10 and the asphalt connecting pipe 11 through a tee;

[0017] This product includes a pressure sensor and a detection circuit. The pressure sensor is set at the connection between the asphalt connecting pipe and the asphalt nozzle, and the detection circuit is connected to the pressure sensor;

[0018] The pressure sensor includes a housing 1. A blind hole is arranged inside the housing 1. A pipeline interface 2 is arranged at the opening of the blind hole as shown. A main piston 4 is arranged in the middle of the blind hole, and a main piston 4 is arranged at the opening of the blind hole. Spring 5, the other end of the spring 5 is fixedly connected to the bottom of the blind hole, and a contact switch 6 is also arranged at the bottom of the blind...

Abstract

The invention discloses a nozzle-blocking sensing mechanism for a spreading machine. The nozzle-blocking sensing mechanism comprises a shell, wherein a blind hole is formed inside the shell; a pipeline connector is formed at an opening of the blind hole; a main piston is arranged in the middle of the blind hole; a spring is arranged at the position, back to the opening of the blind hole, of the main piston; the other end of the spring is fixedly connected with the bottom of the blind hole; a contact switch is also arranged at the bottom of the blind hole. When the pressure of fluid at the pipeline connector is greater than a preset value of the spring, the spring is compressed, the piston contacts the contact switch, and a detection circuit is conducted; the detection circuit comprises a connecting port and a detection end connected with the connecting port; the connecting port is connected with a contact spring; when the contact spring is switched on, the detection circuit is conducted, and the detection end gives a signal prompt.

Description

technical field [0001] The invention relates to a blocking sensor mechanism of a spreader, which belongs to the field of road engineering. Background technique [0002] When the spreader is spreading, if the temperature is low, the nozzle will be blocked, which will cause uneven spreading and affect the quality of the project. Contents of the invention [0003] The purpose of the present invention is to provide a sensor mechanism for the blockage of the spreader, so that the operator can find out in time when the nozzle is blocked or the spraying is not smooth, and carry out relevant treatment. [0004] The present invention is realized by following method: [0005] A spreader blockage sensing mechanism, including a pressure sensor and a detection circuit, the pressure sensor is arranged at the connection between the asphalt connecting pipe and the asphalt spout, and the detection circuit is connected to the pressure sensor; [0006] The pressure sensor includes a housin...
