Description

Technical Field

[0001] The invention relates to the technical field of mobile weighing vehicles, and in particular to an automatic cleaning track device for a mobile weighing vehicle. Background Art

[0002] Since the beginning of the 21st century, with the development of science and technology, new issues have been raised for raw materials in the iron and steel metallurgy, electronics, chemical industry, building materials and other industries, and the use conditions have become more and more demanding and special. The preparation of the required raw materials must go through necessary batching and mixing processes. In particular, in the process of weighing materials, the traditional process uses belt weighing scales for weighing, but the weighing accuracy is low. Currently, mobile weighing vehicles are mainly used for material weighing. Due to the different properties and particle sizes of various materials, some materials will fall on the track of the mobile weighing vehicle, and the running speed of the mobile weighing vehicle is generally 40m / min, which leads to unstable operation of the mobile weighing vehicle and even derailment, seriously affecting the normal production. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides an automatic cleaning device for a mobile weighing vehicle track, which can quickly clean the materials deposited on the weighing vehicle track and ensure the safe and stable operation of the weighing vehicle.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An automatic cleaning track device for a mobile weighing vehicle comprises a front wheel cleaning device, a rear wheel cleaning device, a water tank, a solenoid valve, a cleaning pipe, a rubber brush, a pipe rotating device, a limit switch and a control system; the water tank is installed on the body of the mobile weighing vehicle, the water tank is connected to the cleaning pipe, the solenoid valve is installed on the cleaning pipe, the control system controls the switch of the solenoid valve, and a high-pressure nozzle and a rubber brush are installed at the end of the cleaning pipe; the pipe rotating device is connected to and drives the cleaning pipe to rotate, and the control system controls the pipe rotating device; two limit switches are respectively installed at the front end and the rear end of the weighing vehicle, and the limit switches are connected to and control the travel motor of the mobile weighing vehicle; the front wheel cleaning device and the rear wheel cleaning device are respectively installed at the bottom of the front wheel and the rear wheel.

[0006] The control system includes a PLC controller, and the PLC controller controls the switch of the solenoid valve through a relay.

[0007] The solenoid valve is an electric ball valve.

[0008] It also includes a pipeline rotating joint, through which the water tank is connected to the cleaning pipeline.

[0009] The pipeline rotating device includes a pipeline rotating motor, a large gear and a small gear. The pipeline rotating motor is connected to the small gear, the small gear is meshed with the large gear, and the large gear is installed on the cleaning pipeline; the pipeline rotating motor drives the cleaning pipeline to rotate, and the control system controls the rotating motor.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1) The present invention includes a front wheel cleaning device, a rear wheel cleaning device, a high-pressure nozzle and a rubber brush. The high-pressure nozzle sprays high-pressure mist water droplets on the track. After the materials not cleaned by the front wheel cleaning device are flushed again with high pressure, the rubber brush will clean the water droplets and materials attached to the track again; finally, the rear wheel cleaning device fixed on the rear wheel of the mobile weighing vehicle will clean the track again, so that the materials on the track are completely cleaned.

[0012] 2) When the running direction of the mobile weighing vehicle changes, a conversion signal is sent, and the water spray pipe is driven by the control system to rotate 180°, ensuring that the front wheel cleaning device, water spray mist, rubber brush, and rear wheel cleaning device play a cleaning role in turn.

[0013] 3) The present invention is provided with a limit switch. When the weighing vehicle approaches an obstacle, the limit switch controls the traveling motor of the mobile weighing vehicle to stop running, and the weighing vehicle will automatically reduce the running speed until it stops, thereby ensuring the safe operation of the weighing vehicle.
