Description

Technical Field

[0001] The utility model relates to a flat warehouse discharging mechanism, in particular to a flat warehouse pit material supporting and clearing mechanism, belonging to the technical field of bulk material discharging equipment. Background Art

[0002] The storage yard of a flat warehouse is rectangular, and the width of the yard is relatively wide, often reaching 30 to 40 meters. There is a trend of getting wider and wider, and the depth sometimes reaches more than 200 meters. Materials need to be discharged through a dedicated warehouse unloading machine, which extends along the full width of the flat warehouse and moves forward along the depth of the flat warehouse; a pit extending along the full depth is set in the middle of the flat warehouse in the width direction. While the warehouse unloading machine moves forward, it transports the materials in the width direction to the center pit of the flat warehouse. A buried scraper conveyor is set in the pit to transport the materials out of the warehouse.

[0003] Traditionally, a large civil enclosure structure is required above the pit to accommodate the head-end walking mechanism of the warehouse unloading machine. The top of the civil enclosure structure is often connected to the middle partition wall through a long slope. The construction period is long and the cost is high, which further reduces the effective storage space.

[0004] The Chinese utility model patent with the announcement number CN 214567948U discloses a discharge door device, including a flap that can be opened and closed symmetrically, the tops of the two flaps are symmetrically hinged on the two sides of the flap top beam, the middle of the back of the two flaps is hinged with a connecting rod, and the lower end of the connecting rod is hinged on the connecting rod hinge seat; the bottom of the flap top beam is hinged with an electric push rod, the bottom of the electric push rod is fixed on the electric push rod support, the electric push rod support and the connecting rod hinge seat are respectively fixed on the discharge door bottom beam, the front and rear ends of the flap top beam are respectively provided with X guide wheels, the upper and lower sides of the X guide wheel are respectively provided with Y guide wheels, and the X guide wheel and the Y guide wheel are jointly embedded in the vertical support beam slide groove of the discharge door column. A canopy cover bracket is installed on the top of the discharge door column, and a canopy cover is fixed above the canopy cover bracket, and the canopy cover is symmetrically covered above the top of the two flaps in a herringbone shape.

[0005] This technical solution avoids the need for building civil engineering enclosures, and materials can be piled normally on top of it, expanding the storage space and facilitating gravity discharge of materials. However, many components are prone to failure and are buried under the material pile, so a deeper pit must be set up to facilitate the installation of the drive and power supply mechanism, and an inspection channel must be set up for maintenance personnel to enter the pit for inspection and maintenance work.

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific figures. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figures 1 to 5 As shown, the material support and clearing mechanism of the flat warehouse pit of the utility model comprises a material blocking belt 8, an intermediate scraper 5 and a belt clearing auger 7. The top of the flat warehouse pit is covered with a material-permeable cover plate, the middle of which is a blind plate, and both sides of the blind plate are grilles that can leak materials and are connected to the blind plate as a whole. The tops of the two grilles are respectively covered with a material blocking belt 8, one side of the material blocking belt 8 is placed on the edge of the pit, and the other side is placed on the edge of the blind plate.

[0029] The material blocking belt 8 extends along the full length of the grille, and an upwardly raised belt aqueduct 3 is provided in the middle of the warehouse unloading machine. The belt aqueduct 3 is an isosceles trapezoid, with smooth transitions at the corners and arc chamfers, belt guide wheels or aqueduct guide rollers. The travel drive shaft 2 of the warehouse unloading machine is located below the high point of the belt aqueduct 3. The material blocking belt 8 goes up around the upwardly raised belt aqueduct 3 and then goes down to the top of the grille.

[0030] Both sides of the material-blocking belt 8 are restricted between the wall panels on both sides of the belt aqueduct 3. The upper end of the belt aqueduct 3 is provided with a plurality of aqueduct limiting rods 3a to prevent the material-blocking belt 8 from falling out of the aqueduct.

[0031] Belt tensioning wheels 9 are respectively provided at both ends of the material blocking belt 8. For the convenience of display, the belt tensioning wheels 9 at both ends are moved to a position close to the warehouse discharge machine in the figure.

[0032] In the material storage state, the material blocking belt 8 covers the grille and obtains reliable support from the grille, can bear the weight of the material, and reliably close the pit.

[0033] When unloading, as the unloading machine moves forward, the material-blocking belt 8 at the unloading machine turns upward and passes through the belt aqueduct 3 to cross the unloading machine, forming a void under the belt aqueduct 3, exposing the grille. The unloading equipment on the left and right sides of the unloading machine transports the materials in the width direction of the bungalow warehouse to the central pit, and the materials leak into the pit from the grille. The buried scraper conveyor in the pit transports the materials out of the warehouse, and the material-blocking belt 8 behind the unloading machine covers the pit again.

[0034] The materials on the blind plate leak from the two grilles by natural collapse, and some materials will still accumulate. Therefore, an intermediate scraper 5 is arranged between the two belt aqueducts 3. The intermediate scraper 5 is wrapped in a triangle and the bottom edge of the triangle is attached to the top of the blind plate. The driving sprocket 4a of the intermediate scraper 5 is located on the top of the warehouse discharge machine. The intermediate scraper motor 4 and its reducer are installed on the intermediate cleaning machine frame 1a, the intermediate cleaning machine frame 1a is fixed on the warehouse discharge machine base 1, and the driving sprocket 4a is installed at the output end of the intermediate scraper reducer.

[0035] The driven sprockets 6 of the middle scraper 5 are symmetrically located at the front and rear sides of the bin unloading machine and are respectively fixed on the driven shaft of the middle scraper 5. Belt cleaning augers 7 are respectively installed at both ends of the driven shaft of the middle scraper. Each belt cleaning augers 7 transports the material on the blocking belt 8 to the direction where the middle scraper is located. The middle scraper lifts the material on the blind plate upwards, so that it falls on the grille from the gap between the scraper and the blocking belt 8.

[0036] The above description is only the preferred feasible embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model, but does not limit the scope of patent protection of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
