Abstract

An anti-jam hopper, relating to a hopper used in the ribbon conveyer, belonging to the technique field of the material handling device; such utility model is used to solve the clogging of the hopper in-service. The hopper is obliquely arranged; After the improvement, part of the upper tipping hopper wall at the outlet end of the hopper is changed as the tongue blade, of which the upper part is flexibly hinged with the upper tipping hopper wall; the outer wall is provide with the vibrating reed; the other end of the vibrating reed is connected with the basal face of the raised shell at the outside of the tongue blade. Also, the basal face of the raised shell is arranged with the limit switch which is positioned on the turn-up track at the lower end of the tongue blade. When the slight clogging occurs, the movable tongue blade is turned up due to the press and automatically looses the clogged materials via the vibration of the re-set vibrating reed. In case the serious clogging occurs, the movable tongue blade will turn up greatly and touch the limit switch to send out the alarm. Thus, the abnormal feeding is prevented as the material supply stops. Therefore, the clogging inside the hopper could be solved timely and this utility model is applicable to be used for the band conveyor.

Description

The anti-clogging funnel

Technical field

The utility model relates to the mass transport funnel, and especially funnel in the ribbon conveyer belongs to mass transport utensil technical field.

Background technology

Material during by funnel regular meeting adhere to be bonded on the headwall, form the adhesive linkage piece, influence the unobstructed property of discharge, stop up funnel when serious, the conveying of interruption raw material or the discharge of waste material.For preventing that funnel from stopping up, on structure design, funnel is done greatly as far as possible and paved.The traffic capacity of material is by the design of crescendo trend in the belt conveyer, promptly following one belt is bigger than the traffic capacity of last one belt, guarantee the unobstructed conveying of material with this, like this, will make the infundibular body one-level bigger than one-level, the last anti-clogging problem that can't solve funnel eventually because of the restriction that is subjected to the final stage structural volume well for this reason, also should be sought more scientific and reasonable terms of settlement and approach.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of anti-clogging funnel.

The alleged problem of the utility model realizes with following technical scheme:

A kind of anti-clogging funnel, the infundibular body 1 that is obliquely installed is arranged in the formation, its improvement is, part wall on the headwall that tilts of infundibular body 1 exit end is pulled to the tongue of activity and is pulled 2, tongue is pulled 2 upper ends and is movably hinged, pulls outward and be connected with tongue 3 on the face with the headwall that tilts, the other end of tongue 3 is connected with the bottom surface that tongue is pulled the protruding housing 4 in the outside, and protruding housing bottom surface also is mounted with limit switch 5, and limit switch 5 is positioned at tongue and pulls digging on the rotational trajectory of 2 lower ends.

Above-mentioned anti-clogging funnel, described tongue are pulled 2 and are pulled for up-narrow and down-wide taper.

It is that movable tongue is pulled that the utility model makes the tilt part headwall of headwall of inclination funnel, can make movable tongue pull that the pressurized low-angle is dug and the loosening voluntarily stockpile that stops up under the kinetic energy vibrations that reset of tongue when slight the obstruction occurring, when the severe obstruction occurring, movable tongue is pulled wide-angle and is dug, the touching limit switch sends warning, prevents the improper feeding under the fracture situation, and the plugging fault of funnel can in time be found and handle,, suitable use as the funnel in the belt conveyer etc.

Description of drawings

Fig. 1 is the utility model structural representation.

The parts label is respectively in the accompanying drawing: 1-infundibular body, 2-tongue are pulled, 3-tongue, 4-projection housing, 5-limit switch, 6-jointed shaft, 7-guide cover, 8-are carried zone face, 9-carrying roller, 10-cylinder, 11-frame.

The specific embodiment

In the illustrated embodiment, infundibular body 1 is obliquely installed, the upper end is inlet point, and the lower end is a discharging opening, be connected with guide cover 7 on the discharging opening, cover mouthful is connected with conveying zone face 8 in the belt conveyer, and 9 is the carrying roller under the conveying zone face, 10 for carrying the cylinder at endless belt two ends, and 11 is the frame of belt conveyer.When occurring stockpiling material in the infundibular body 1, constantly pile up the stockpile that expands and promote tongue to pull 2 jointed shafts 6 with the upper end be that outwards dig in the axle center, when digging certain angle, tongue is pulled 2 lower ends and is touched limit switch 5 on protruding housing 4 inner bottom surfaces, give the alarm and cut off the electricity supply, stop the conveying of material.Tongue pulls 2 for wear-resistant material, and up-narrow and down-wide taper is pulled structure and helped it and reset fast under the deadweight effect.

Claims

1. anti-clogging funnel, bevelled infundibular body [1] is arranged in the formation, it is characterized in that, part wall on the headwall that tilts of infundibular body [1] exit end is pulled to the tongue of activity and is pulled [2], tongue is pulled [2] upper end and is movably hinged, pulls outward and be connected with tongue [3] on the face with the headwall that tilts, the other end of tongue [3] is connected with the bottom surface that tongue is pulled the protruding housing [4] in the outside, and protruding housing bottom surface also is mounted with limit switch [5], and limit switch [5] is positioned at tongue and pulls digging on the rotational trajectory of [2] lower end.

2. anti-clogging funnel according to claim 1 is characterized in that described tongue is pulled [2] and pulled for up-narrow and down-wide taper.
