The invention relates to the field of concrete processing, in particular to an anti-blocking device for a concrete discharging bin.

Background

In the prior art, in the preparation process of concrete, different types of materials are often required to be stirred and premixed, and the premixed materials are converged to a discharge port at the lower end of a discharge bin under the action of gravity. Because the materials have certain viscosity, such as sand and fly ash, a certain amount of materials can be adhered to the inner wall of the discharge hole after the materials are discharged from the discharge hole, and the materials are easy to block the discharge hole, so that the continuity of the subsequent concrete preparation work is influenced.

At present, after the discharge gate blocks up, need use the dredging strip to insert and carry out the manual work mediation in the discharge gate, operate very trouble like this, work intensity of labour is great, and the efficiency of discharge gate mediation is lower.

The invention aims to provide an anti-blocking device for a concrete discharging bin, so as to realize automatic dredging of a discharging port and avoid material blockage of the discharging port.

In order to achieve the purpose, the invention adopts the following technical scheme: the concrete discharging bin anti-blocking device comprises a rack and a discharging port, wherein the discharging port comprises an upper discharging pipe and a lower discharging pipe which are vertically arranged, the upper discharging pipe and the lower discharging pipe are both fixed on the rack, a flexible discharging pipe is arranged between the upper discharging pipe and the lower discharging pipe and is flexible, the upper discharging pipe, the flexible discharging pipe and the lower discharging pipe are communicated, and the length of the flexible discharging pipe is greater than the sum of the length of the upper discharging pipe and the length of the lower discharging pipe; a plurality of moving rods which do reciprocating motion are arranged on the outer side of the discharge port, the moving rods are uniformly distributed around the circumference of the flexible discharge pipe, and one end of each moving rod is abutted against the flexible discharge pipe; and a driving mechanism for driving the moving rod to reciprocate is arranged on the outer side of the discharge port.

The principle and the advantages of the scheme are as follows: in the scheme, the upper discharging pipe, the flexible discharging pipe and the lower discharging pipe are communicated to form a discharging port, and materials are discharged from the discharging bin sequentially through the upper discharging pipe, the flexible discharging pipe and the lower discharging pipe. The upper discharging pipe and the lower discharging pipe are positioned at two ends of the flexible discharging pipe and are connected and supported. When the inside of discharge gate blockked up there is the material, drive the carriage release lever reciprocating motion through actuating mechanism, when the carriage release lever when being close to flexible discharging pipe direction removal, the one end that carriage release lever and flexible discharging pipe offset extrudees flexible discharging pipe, thereby make the bore shrink at the position that flexible discharging pipe was promoted by the carriage release lever diminish, when the carriage release lever removed to the direction of keeping away from flexible discharging pipe, the bore at the position that flexible discharging pipe contracts resets, the bore of flexible discharging pipe periodically changes on having realized the discharge gate from this, the continuous change of bore of flexible discharging pipe and tremble the material of adhesion on the inner wall down, can prevent flexible discharging pipe putty. Because the length of flexible discharging pipe is greater than the length sum of upper discharging pipe and lower discharging pipe, consequently whole discharge gate mainly uses flexible discharging pipe as the owner, and the material of adhesion is less on long discharging pipe inner wall and the lower discharging pipe inner wall, and is little to the influence of whole discharge gate putty, so through can not realize just that whole discharge gate can not the putty on making flexible discharging pipe.

Preferably, as an improvement, the driving mechanism comprises a motor, a driving gear, a rotating ring sleeved outside the flexible discharging pipe and a fixing ring sleeved outside the rotating ring, a plurality of moving rods are uniformly distributed on the rotating ring in the circumferential direction, the moving rods are connected to the rotating ring in a sliding manner along the radial direction of the rotating ring, an elastic part is connected between the moving rods and the rotating ring, a plurality of bulges are distributed on the inner wall of the fixing ring in the circumferential direction, and one end of each moving rod, far away from the flexible discharging pipe, abuts against the bulge; the outer wall of the rotating ring is provided with teeth which are uniformly distributed on the circumference, the teeth on the outer wall of the rotating ring are meshed with the driving gear, and the output shaft of the motor is connected with the driving gear; the top of the flexible discharge pipe is rotatably connected to the bottom of the upper discharge pipe; the bottom of the flexible discharge pipe is rotatably connected to the top of the lower discharge pipe; one end of the movable rod far away from the bulge is fixedly connected to the outer wall of the flexible discharge pipe.

The motor drives the driving gear to rotate, the driving gear drives the rotating ring to rotate through meshing with teeth on the outer wall of the rotating ring, and the rotating ring drives the moving rod to slide on the inner wall of the fixing ring, wherein one end of the moving rod, far away from the flexible discharging pipe, is located on the outer wall of the rotating ring. The inner wall of the fixing ring is provided with the bulge, so that the end part of the moving rod continuously and intermittently offsets with the bulge in the sliding process of the end part of the moving rod on the inner wall of the fixing ring, when the end part of the moving rod offsets with the bulge, the bulge pushes the moving rod, and the moving rod extrudes the flexible discharge pipe, so that the caliber of the extruded part of the flexible discharge pipe shrinks and becomes small, and meanwhile, the elastic part deforms and stores force; when the end part of the movable rod is not abutted against the bulge, the movable rod is far away from the flexible discharge pipe under the action of the elastic piece, and the caliber of the extruded part of the flexible discharge pipe is increased. From this, realized the simultaneous drive of reciprocating motion of a plurality of carriage bars through this scheme, need not to drive every carriage bar alone, actuating mechanism's structure sets up simply, rationally and ingenious.

The top of the flexible discharge pipe is rotatably connected to the bottom of the upper discharge pipe; the bottom of the flexible discharging pipe is rotatably connected to the top of the lower discharging pipe, so that the flexible discharging pipe can rotate between the upper discharging pipe and the lower discharging pipe.

Bellied one end and flexible discharging pipe fixed connection are kept away from to the carriage release lever, and when the swivel becket rotated like this, the swivel becket drove flexible discharging pipe through the carriage release lever and rotates between last discharging pipe and lower discharging pipe, the aim at that sets up like this: 1. when the rotating ring drives the moving rod to rotate, the end, far away from the protrusion, of the moving rod cannot slide relative to the outer wall of the flexible discharging pipe to cause friction, the end of the moving rod and the outer wall of the flexible discharging pipe are prevented from rubbing to cause damage to the flexible discharging pipe, and the service life of the flexible discharging pipe is prolonged. 2.

So do not set up the scraper blade in whole discharge gate in this scheme, because set up the scraper blade in whole discharge gate, the volume of scraper blade is great, and the scraper blade can occupy certain space and influence the normal ejection of compact of material, because the length of going up discharging pipe and discharging pipe down is all smaller in this scheme, therefore the length of scraper blade can not be great, and the volume of scraper blade is less to influence lessly to the normal unloading of material.

Preferably, as an improvement, the rotating ring is provided with an upper knocking mechanism and a lower knocking mechanism, and the reciprocating movement of the moving rod drives the upper knocking mechanism and the lower knocking mechanism to knock the outer wall of the upper discharging pipe and the outer wall of the lower discharging pipe respectively.

From this, the carriage release lever is at reciprocating motion in-process, goes up knocking mechanism and knocks discharging pipe and discharging pipe down respectively with lower knocking mechanism to can make discharging pipe and discharging pipe produce the vibration and be favorable to the material dropped by scraping down.
