Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking structures, in particular to an anti-blocking structure of a reciprocating feeder. Background Art

[0002] The reciprocating feeder uses a crank-connecting rod mechanism to drag the bottom plate with a downward inclination of 5° to make a linear reciprocating motion on the roller. When the motor is turned on, the elastic coupling, reducer, and crank-connecting rod mechanism drag the inclined bottom plate to make a linear reciprocating motion on the roller, and the coal is evenly unloaded to the transportation machinery or other screening equipment. In this way, the coal or other loose granular and powdery materials with low abrasiveness and low viscosity are evenly unloaded from the feeding equipment to the receiving equipment. Reciprocating feeders are widely used in coal mines, coal preparation plants, mines and other industries in my country.

[0003] Most of the existing reciprocating feeders do not have an anti-clogging function. When a large amount of material is added to the feed hopper of the feeder at one time, it is easy to cause the feed hopper to be blocked, resulting in feeding interruption, thereby affecting the efficiency of material transportation, causing inconvenience to the user, failing to meet the user's usage needs, and reducing the practicality of the reciprocating feeder. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an anti-blocking structure for a reciprocating feeder, which overcomes the deficiencies of the prior art and effectively solves the problem in the prior art that when a large amount of material is added to the feed hopper of the feeder at one time, the feed hopper is easily blocked, resulting in feeding interruption, thereby affecting the efficiency of material transportation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A reciprocating feeder anti-blocking structure comprises a feed hopper, an inner wall of one side of the feed hopper is connected to a cleaning mechanism, and an outer wall of one side of the feed hopper is connected to a driving mechanism, the cleaning mechanism comprises a U-shaped frame, sliding bars fixed to the outer walls at both ends of the U-shaped frame, a rotating rod rotatably connected to the top of the inner walls at both ends of the U-shaped frame, a scraper bar equidistantly sleeved and fixed on the rod wall of the rotating rod, and a torsion spring sleeved and fixed at both ends of the rod wall of the rotating rod, the driving mechanism comprises a fixed frame, a servo motor installed on the top of the outer wall on one side of the fixed frame, a turntable rotatably connected to the top of the outer wall on the other side of the fixed frame, a connecting rod rotatably connected to the turntable, a connecting head rotatably connected to the connecting rod, a U-shaped rod fixed to the top of the connecting head, and a connecting plate fixed to the other end of the U-shaped rod.

[0007] The turntable is driven to rotate by the servo motor, and the rotating turntable drives the connecting head to move up and down through the connecting rod. The connecting head moves vertically along the guide block, and the U-shaped rod drives the cleaning mechanism to move up and down. With the reset characteristics of the freely rotating rotating rod and the torsion spring, when the cleaning mechanism moves upward along the slide, it is blocked by the material and the scraper bar rotates into the U-shaped frame, so that the cleaning mechanism can move smoothly to the top of the feed hopper, and then under the action of the torsion spring, the scraper bar rotates and pops out from the U-shaped frame. When falling, the popped-up scraper bar presses the material in the feed hopper downward into the feeder.

[0008] Preferably, slide grooves are fixed at both ends of the inner wall of one side of the feed hopper, and the two slide grooves are slidably connected to the two slide bars respectively.

[0009] Through the sliding cooperation between the slide bar and the slide groove, the cleaning mechanism can move up and down in the feed hopper in the vertical direction.

[0010] Preferably, through holes are provided at the tops of the outer walls on both sides of the U-shaped frame, and positioning rods are inserted into the through holes.

[0011] The connected cleaning mechanism and driving mechanism are plugged and fixed by means of a positioning rod.

[0012] Preferably, a guide block is fixed to one side of the top of the feed hopper, and the guide block and the U-shaped rod form a plug-in sliding fit.

[0013] The U-shaped rod is moved vertically along the guide block by means of the provided guide block.

[0014] Preferably, the outer wall of one side of the turntable and the connecting head are both fixed with protruding rods, and the two protruding rods are rotatably connected to the two ends of the connecting rod respectively.

[0015] The convex rod is connected with the connecting rod by rotation, so that when the turntable rotates, the connecting head is driven to move up and down through the connecting rod.

[0016] Preferably, one end of the connecting plate is provided with a plug hole penetrating through the other end, and the plug hole is plug-fitted with the positioning rod.

[0017] The two ends of the connecting plate are butted against the inner walls of the two ends of the U-shaped frame, and then the positioning rod is inserted into the insertion hole, so that the connecting plate and the U-shaped frame are plugged and fixed.

[0018] The beneficial effects of the utility model are:

[0019] The turntable is driven to rotate by a servo motor, and the rotating turntable drives the cleaning mechanism to move up and down through a U-shaped rod. When the cleaning mechanism moves upward along the slide slot, it is blocked by the material and the scraper bar rotates into the U-shaped frame, so that the cleaning mechanism can smoothly move to the top of the feed hopper. Then, under the action of the torsion spring, the scraper bar rotates and pops out from the U-shaped frame. When falling, the popped-up scraper bar presses the material in the feed hopper downward into the feeder, effectively solving the problem in the prior art that when a large amount of material is added to the feed hopper of the feeder at one time, the feed hopper is easily blocked, resulting in feeding interruption, thereby affecting the efficiency of material transportation.
