[0001] The utility model relates to a flat warehouse discharging mechanism, in particular to a flat warehouse discharging machine, 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 power supply and personnel entering the pit for maintenance.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0033] 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.

[0034] like Figures 1 to 7As shown, the flat warehouse unloading machine of the utility model includes an unloading machine base 1, on which are mounted an unloading walking mechanism, a material supporting and clearing mechanism, and an unloading mechanism. The upper port of the central pit is covered with a material-permeable cover plate, and the material-permeable cover plate is a blind plate 10a in the middle of the width direction of the pit. Both sides of the blind plate 10a are grilles 10b that can leak materials, and the grilles 10b are connected to the blind plate 10a as a whole. The unloading mechanism is an annular scraper conveyor 9 that discharges materials toward the pit, and can also be a conveying auger.

[0035] The material support and cleaning mechanism comprises a material blocking belt 8, a cleaning scraper 5 and a belt cleaning auger 7. The two grilles 10b 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 10a.

[0036] The material blocking belt 8 extends along the full length of the grille 10b, and an upwardly raised arched aqueduct 3 is provided in the middle of the warehouse unloading machine. The arched aqueduct 3 is an isosceles trapezoid, and the corners are smoothly transitioned and are respectively provided with arc chamfers, belt guide wheels or aqueduct guide rollers. The travel drive shaft 2b of the warehouse unloading machine is located below the high point of the arched aqueduct 3. The material blocking belt 8 goes up around the upwardly raised arched aqueduct 3 and then goes down back to the top of the grille 10b.

[0037] Both sides of the material-blocking belt 8 are restricted between the two side wall panels of the arched aqueduct 3. The upper end of the arched aqueduct 3 is provided with a plurality of aqueduct limiting rods 3a to prevent the material-blocking belt 8 from falling out of the groove.

[0038] Belt tensioning wheels 8a are respectively provided at both ends of the material blocking belt 8. For the convenience of display, the belt tensioning wheels 8a at both ends are moved to a position close to the warehouse discharge machine in the figure.

[0039] In the material storage state, the material blocking belt 8 covers the grille 10b and obtains reliable support from the grille 10b, can bear the weight of the material, and reliably close the pit.

[0040] The middle part of the travel drive shaft 2b is connected to the output end of the warehouse outgoing travel reduction box 2a, the warehouse outgoing travel reduction box 2a is fixed on the warehouse outgoing machine base, and the input end of the warehouse outgoing travel reduction box 2a is driven by the warehouse outgoing travel motor 2;

[0041] On the floor of the flat warehouse, multiple channel steels are symmetrically arranged extending in the full depth direction, and the openings of each channel steel face upward and are distributed with warehouse exit walking chains 2d, and walking chain tensioning mechanisms 2e are respectively arranged at both ends of the warehouse exit walking chains 2d. Multiple walking drive sprockets 2c are symmetrically arranged on the walking drive shaft 2b, and the walking drive sprockets 2c and their steering sprockets are respectively engaged with the warehouse exit walking chains 2d.

[0042] When unloading, as the unloading machine moves forward, the material-blocking belt 8 at the unloading machine turns upward and passes through the arched aqueduct 3 over the unloading machine, forming a void under the arched aqueduct 3, exposing the grille 10b. 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 10b. The buried scraper conveyor 11 in the pit transports the materials out of the warehouse, and the material-blocking belt 8 behind the unloading machine covers the pit again.

[0043] The material on the blind plate 10a leaks from the two grids 10b by natural collapse, and a part of the material will still accumulate. Therefore, a cleaning scraper 5 is arranged between the two arched aqueducts 3. The cleaning scraper 5 is wrapped in a triangle and the bottom edge of the triangle is attached to the top of the blind plate 10a. The cleaning driving sprocket 4a of the cleaning scraper 5 is located on the top of the warehouse discharge machine.
