Description

Bucket elevator

Technical Field

The invention relates to the technical field of elevators, in particular to a bucket elevator.

Background

Present bucket elevator is mainly to carry the material to a hoisting device of eminence from the low, it is mainly by upper and lower two pairs of sprockets, chain and hopper are constituteed, its theory of operation is mainly when the material that the hopper stored through chassis bottom, dig wherein and get, then it is rotatory along with the rotatory chain that drives of sprocket, thereby make the hopper rise, when the hopper reachs the opposite side at top, the hopper can slowly become the opening and fall the material down, thereby accomplish the transport of a material, but present bucket elevator has following problem all the time:

the hopper of current bucket elevator all is fixed mounting on the chain, he can turn to along with turning to of chain takes place together, and such mode makes the hopper can all be in the process of digging of high resistance when chassis bottom digs the material, make the load of motor continuously maintain on a high level like this, increase the consumption of motor, and do not do benefit to the normal use of chain like this yet, make the bearing capacity of chain too big, lead to the broken chain easily, and when unloading at the top of casing, because hopper self does not possess the rotation effect, when the mouth of hopper begins the downward sloping, just started to unload, but the hopper does not reach the discharge opening at this time, even current the feed back condition that reduces the material through the hyoplastron, but still have more material production feed back, lead to the transport rate reduction of material.

Disclosure of Invention

The invention provides a bucket elevator, which has the advantages of high conveying rate, no material return phenomenon and long service life of a chain, and solves the problems in the background art.

The invention provides the following technical scheme: the utility model provides a bucket elevator, includes the casing, there is the sprocket inside through pivot swing joint of casing, it has the chain to sprocket swing joint, fixed mounting has the fixed block on the chain, fixed mounting has the intermediate lever on the fixed block, swing joint has the hopper on the intermediate lever, casing inner wall upper portion fixed mounting has limit guide, limit guide's lower part fixed mounting has the pin, the inner wall fixed mounting of casing has the play hopper that is located the pin lower part.

Preferably, the hopper contains the connecting rod, the quantity of connecting rod is two, the one end and the intermediate lever swing joint of connecting rod, the other end and the lateral wall swing joint of connecting rod, the front and the back of lateral wall fixed mounting respectively have four spacing wheels, the both sides of lateral wall inner wall bottom fixed mounting respectively have the sloping block, the bottom fixed mounting of lateral wall has discharging device.

Preferably, discharging device contains the bracing piece, the bracing piece is fixed mounting at the both ends of lateral wall bottom respectively, the both ends of bracing piece fixed mounting has the side lever respectively, equidistant fixed mounting has rotatory minor axis on the side lever, fixed mounting has the runner on the rotatory minor axis, swing joint has the belt on the runner, the back fixedly connected with switch block of belt, the positive fixed mounting of middle rotatory minor axis has the switch lever.

Preferably, the cross-sectional shape of the switch block is a parallelogram.

Preferably, the installation height of the limiting guide rail is the same as the height of the limiting wheel after the hopper reaches the upper parallel position.

Preferably, the stop lever is located in the middle above the discharge hopper and below the bottom of the hopper, and the width of the upper opening of the discharge hopper is greater than the sum of the width of the lower portion of the hopper and the distance the hopper moves during the opening of the discharge device.

The invention has the following beneficial effects:

1. this bucket elevator changes into four pairs of sprocket and each two pairs from top to bottom through two traditional pairs of sprockets, swing joint has the hopper on the intermediate lever through fixed connection on the fixed block above that between the sprocket for the hopper can remain throughout and can not take place the phenomenon of reversing, and all is in the state of forward position at the in-process of rising and unloading, just so can guarantee completely can not produce the phenomenon of feed back because of need the hopper to reverse when unloading, improves the transport rate of material.

2. The bucket elevator has the advantages that the hopper is movably connected to the middle rod through the connecting rod, so that when the bottom is used for digging, due to the rotation of the hopper, the hopper can incline to a certain degree while digging, the situation that the whole hopper digs materials hard and forcibly increases the bearing capacity of a chain is avoided, the service life of the chain is prolonged, in addition, when the upper part is used for discharging, the horizontal relative position of the whole hopper can be limited by the rolling of the limiting wheels in the limiting guide rails, the hopper can be ensured to be always in a horizontal state, in addition, the baffle rod is arranged above the middle of the discharging hopper communicated with the back and below the hopper, when the switch rod moves to the baffle rod, the discharging device at the bottom of the hopper is opened under the blocking effect of the baffle rod, so that the materials completely fall into the discharging hopper in the moving process of the hopper, and zero material return is realized, further improving the conveying rate of the materials.
