The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.

In the utility model, in the situation that do opposite explanation, the noun of locality of use typically refers to " upper and lower " direction among Fig. 1 to Fig. 5, i.e. described chute " upper and lower " direction under the use state such as " upper and lower ".

As shown in Fig. 1 to Fig. 5, the utility model provides a kind of chute, this chute comprises the body 20 with entrance and exit, wherein, this chute also comprises the chute putty detecting device 50 that is arranged on body 20 outsides, be formed with on the sidewall of body 20 and detect hole 21, chute putty detecting device 50 comprises cover plate 51, the approach switch 53 of detection lug 52 and this detection lug 52 of induction, cover plate 51 is pivotally secured on the sidewall of chute, and can cover and detect hole 21, one in detection lug 52 and the approach switch 53 can move with cover plate 51, and another one is static with respect to the sidewall of body 20.

Should be understood that, approach switch 53 is electrically connected with controller, and after approach switch 53 passed to controller with signal, controller can be according to this signal material that judges whether to feel oppressed, and moves accordingly.

Material enters body 20 inside from the entrance of chute, in the situation that putty does not occur, as shown in Figure 3, cover plate 51 will detect hole 21 sealings, and approach switch 53 can detect detection lug 52.This moment, approach switch 53 sent the signal that detects detection lug 52 to controller.

If the bottom of chute is stopped up, the material accumulation that can make progress gradually when the material that stops up arrives when detecting hole 21, can enter and detect in the hole 21, and cover plate 51 is pushed open, as shown in Figure 4.Approach switch 53 can't detect detection lug 52, thereby can't send the signal that detects detection lug 52 to controller, putty has occured in the body 20 of this Time Controller judgement chute, controller controllably face belt feeder 30 and cantilever belt conveyor 10 decommissions, thereby the convenient operation personnel keep in repair.

In the utility model, approach switch is arranged on the outside of body 20, can not be subject to the impact of the material of body 20 inner whereabouts.

Owing to being provided with the electric wire that is electrically connected with controller on the approach switch 53, therefore, for the ease of arranging, preferably, can with the sidewall static setting of approach switch 53 with respect to body 20, detection lug 52 being arranged on the cover plate 51.

In the utility model, detection lug 52 can be arranged on the cover plate 51 by modes such as welding, fastener connections, and preferably, detection lug 52 can form as one with cover plate 51, as shown in Figure 3 and Figure 4.Detection lug 52 can be set to cover fully the test side of approach switch 53, thereby can protect approach switch 53, prevents that rainwater, dust from reducing the sensitivity of approach switch to approach switch 53.

In the utility model, to not having specific (special) requirements with the connection location of the sidewall of body 20 on the cover plate 51, as long as pivotly be connected just passable with the sidewall of body 20 outward flange of cover plate 51.Because when putty occured, the material in the chute was piled up from the bottom up, therefore, in order to improve the sensitivity of chute putty detecting device 50, preferably, the upper end of cover plate 51 is connected pivotly with the sidewall of body 20.When entering the bottom of detecting hole 21, the material of piling up from the bottom up can with cover plate 51 jack-up, make detection lug 52 leave the detection range of approach switch 53.

Chute described in the utility model both can be the vertical situation shown in Fig. 1 and Fig. 2, also can be the situation of the three-way pipe shown in Fig. 5.When chute is situation shown in Fig. 1 and Fig. 2, the sidewall of the installation chute putty detecting device 50 on the body 20 is vertical, to detect hole 21 sealings for the ease of cover plate 51, preferably, chute putty detecting device 50 also comprises the supporting walls 54 on the sidewall that is arranged on body 20, cover plate 51 is supported on the supporting walls 54, will detect hole 21 sealings.

Further preferably, the wall height of supporting walls 54 increases from top to bottom gradually, as shown in Fig. 3 and Fig. 4.At this moment, in the situation that putty not, cover plate 51 can rely on the gravity of self will detect hole 21 complete closed.

In these cases, approach switch 53 can be fixed on the supporting walls 54, approach switch can certainly be fixed on the sidewall of body 20.

As mentioned above, body 20 can form the threeway tubulose that comprises an inlet pipe section 23 and two outlet pipe sections 22, and the sidewall slope on the top of outlet pipe section 22 is in vertical direction.In this case, detect on the sidewall on top that hole 21 is formed on outlet pipe section 22, thereby detect hole 21 sealings so that cover plate 51 can descend at the Action of Gravity Field of self.In the utility model, chute putty detecting device is set all in two outlet pipe sections 22.

As shown in Figure 5, can also be formed with boss 51a on the inside face of cover plate 51, this boss 51a can stretch into and detect in the hole 21.The Main Function of boss 51a can seal preferably with detecting hole 21 exactly, prevents that outside rainwater etc. from entering body 20 inside by detecting hole 21.

Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.

Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode.For fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.

In addition, also can carry out combination in any between the various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
