Detailed ways

The technical solutions of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are part of the embodiments of the utility model, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The utility model provides an automatic start-stop device for a belt conveyor, including a belt conveyor, specifically referring to Fig. 1, the difference between it and the prior art is that the belt conveyor 2 includes a frame and a belt strip arranged on the frame, The belt can rotate under the drive of the driving device. There is a particle collection module on the top of the belt conveyor. The outlet of the particle collection module corresponds to the position of the belt so that the particles can accurately fall on the belt. There are several induction modules 3 evenly distributed below; the induction module includes guide shaft 34 and roller bar 32, is provided with spring 35 between guide shaft and the roller bar, and one side of guide shaft 34 is provided with proximity switch 37; A group of funnels 1 arranged side by side are formed, and an induction module is arranged at intervals of 4-6 funnels, and the positions of the induction modules and the feeding ports of the funnels are staggered and arranged.

In the implementation, the particles are collected through the funnel and fall on the belt conveyor. Due to the gravity, the upper belt will be deformed, which will trigger the sensor module located under the upper belt. The sensing module sends a signal to start the belt conveyor. After the particle transmission is completed, the belt returns to its original state, the sensing module sends a signal, and the belt conveyor shuts down within 3 minutes of delay. The device has the advantages of high stability, low cost, easy maintenance, reduced staffing, energy saving, good economic benefits and broad engineering application prospects in actual engineering.

Example 1

The belt conveyor of the present utility model comprises a frame and a belt strip arranged on the frame. A particle collection module is arranged above the belt conveyor. The discharge port of the particle collection module corresponds to the position of the belt strip. There are several sensing modules, preferably 3 or more sensing modules need to be arranged; the sensing module includes a guide shaft and a roller bar, a spring is provided between the guide shaft and the roller bar, and a proximity switch is provided on one side of the guide shaft; particle collection The material module is composed of a group of hoppers arranged side by side, and an induction module is arranged at intervals of 4-6 hoppers, and the position of the induction module and the feeding port of the hopper is staggered.

Preferably, the induction module is connected to the frame of the belt pulley through the support 4, the support is in the shape of a "door", and a group of waist-shaped holes are respectively provided on both sides of the support, and the suitable height of the support can be adjusted through the waist-shaped holes, which can make the induction The module can send out the signal sensitively without exceeding the compression stroke of the spring. Simultaneously, guide shaft 34 is provided with guide shaft bushing 33, and the top of guide shaft is connected with roller bar bottom plate 31, and roller bar is arranged on the roller bar bottom plate, and roller bar is made up of two rollers side by side; Proximity switch is provided on the support Bracket 36, the proximity switch bracket is provided with a connection hole for the proximity switch to pass through and fix.
