Description

Technical Field

[0001] The utility model relates to the technical field of suction specific gravity stone removing machines, in particular to a suction specific gravity stone removing machine with a buffer structure. Background Art

[0002] When the specific gravity stone removing machine works, materials continuously enter the middle of the stone removing screen surface from the feed hopper. Due to the vibration of the screen surface and the action of the air flow passing through the material layer, the porosity between particles increases, and the materials are in a fluidized state, which promotes automatic classification. Stones with a large specific gravity sink to the bottom and contact the screen surface, while grains with a small specific gravity float to the upper layer. Under the action of gravity, inertia force and continuous feeding, they slide down to the clean grain outlet; while stones with a large specific gravity slide upward relative to the stone removing screen surface under the action of the inertia force of the screen vibration system and the air flow, and move to the selection area through the stone gathering area. The specific gravity stone removing machine has the advantages of good stone removing effect, simple structure, small volume and low energy consumption.

[0003] When the specific gravity stone removing machine feeds materials, it is inconvenient to buffer the materials. Therefore, when the material feeding amount is too large, the porosity between the materials is small, and the air flow is difficult to pass through, which affects the classification effect. At the same time, the materials are easy to accumulate on the screen surface, affecting the screening effect. Therefore, a suction specific gravity stone removing machine with a buffer structure is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a suction specific gravity stone removing machine with a buffer structure, which has the effects of increasing the porosity between materials, improving the stone removing effect of the specific gravity stone removing machine body, and avoiding material accumulation.

[0005] The above technical purpose of the utility model is achieved by the following technical solutions: a suction specific gravity stone removing machine with a buffer structure, including a specific gravity stone removing machine body, a feed hopper is fixedly connected to the top of the specific gravity stone removing machine body, a buffer plate is fixedly connected to the inner wall of the feed hopper, a material limiting plate is slidably connected to the bottom of the buffer plate, a material guiding frame is fixedly connected to the inner wall of the feed hopper, a material guiding roller is rotatably connected to the inner wall of the material guiding frame, an elastic layer is fixedly connected to the outer surface of the material guiding roller, a rotating rod is rotatably connected to the inner wall of the feed hopper, a rubber sleeve is fixedly connected to the outer surface of the rotating rod, and a rubber strip is fixedly connected to the outer surface of the rubber sleeve.

[0006] By adopting the above technical solution, when in use, the material falls on the buffer plate and is discharged along the buffer plate. The buffer plate buffers the impact force of the falling material, and the material limiting plate moves, thereby controlling the amount of discharged material. The material flows downward and falls inside the material guiding frame. There is a gap between the material guiding rollers, so that overly large stones will not pass through the material guiding rollers, and the material is preliminarily screened. The large stones roll along the inclination angle of the material guiding frame. There is a discharge port for large stones on the feeding hopper, thereby reducing the stone removal difficulty of the specific gravity stone remover body. The preliminarily screened material continues to fall and is buffered by the rubber sleeve during discharging. The rubber strip is elastic and blocks the falling material. At the same time, under the rotation of the rotating rod, the discharging process of the material is more dispersed, increasing the porosity between the materials and improving the stone removal effect of the specific gravity stone remover body, avoiding the accumulation of materials.

[0007] A further setting of the present utility model is that: one side surface of the rubber strip is fixedly connected with a rubber ring, and the number of the rubber rings is several.

[0008] By adopting the above technical solution, the rubber ring increases the contact area with the material and improves the dispersion strength.

[0009] A further setting of the present utility model is that: the bottom of the feeding hopper is fixedly connected with a feeding pipe, and the feeding pipe extends into the interior of the specific gravity stone remover body.

[0010] By adopting the above technical solution, the feeding pipe corresponds to the interior of the specific gravity stone remover body, and the dispersed material enters the interior of the specific gravity stone remover body.

[0011] A further setting of the present utility model is that: the inner wall of the feeding pipe is rotatably connected with a second rotating rod, and one side surface of the feeding hopper is fixedly connected with a support.

[0012] By adopting the above technical solution, the second rotating rod further increases the porosity of the material, and the top of the support is an inclined surface.

[0013] A further setting of the present utility model is that: a screw conveyor is arranged on the top of the support, and the bottom of the screw conveyor is fixedly connected with a discharge pipe.

[0014] By adopting the above technical solution, the screw conveyor conveys the material, and the material is discharged from the discharge pipe.

[0015] A further setting of the present utility model is that: one side surface of the specific gravity stone remover body is fixedly connected with a material port, and the bottom of the buffer plate is fixedly connected with a support plate.

[0016] By adopting the above technical solution, the material after stone removal is discharged from the material port, and the support plate has a supporting effect.

[0017] A further setting of the present utility model is that one side surface of the support plate is fixedly connected with a cylinder, and the output end of the cylinder is fixedly connected with a telescopic rod.

[0018] By adopting the above technical solution, the cylinder drives the telescopic rod to expand and contract, driving the material limiting plate to move and open and close.

[0019] A further setting of the present utility model is that one side surface of the feed hopper is fixedly connected with an air box, and one side surface of the air box is fixedly connected with a fan.

[0020] By adopting the above technical solution, when feeding, the fan is started, and the fan sucks.

[0021] A further setting of the present utility model is that the inner wall of the air box is fixedly connected with a filter screen, and a dust removal port is opened on one side surface of the feed hopper.

[0022] By adopting the above technical solution, dust enters the air box from the dust removal port, and the dust is adsorbed by the filter screen.

[0023] A further setting of the present utility model is that the bottom of the buffer plate is fixedly connected with a mesh plate, and a negative pressure cavity is left between the buffer plate and the feed hopper.

[0024] By adopting the above technical solution, when the material falls on the guide roller, negative pressure is generated inside the negative pressure cavity, and the material is dust-removed through the mesh holes on the mesh plate.

[0025] The beneficial effects of the present utility model are:

The buffer plate buffers the impact force of the material falling. The material limiting plate moves to control the amount of the material fed. The material flows downward and falls into the guide frame. There is a gap between the guide rollers, so that the over-sized stones will not pass through the guide rollers, and the material is initially screened. The large stones roll along the inclination angle of the guide frame. There is a discharge port for large stones on the feed hopper, thereby reducing the difficulty of stone removal of the specific gravity stoner body.
