Sliding door gatebox and detachable seeder plate
A gatebox for an aircraft comprises an opening operable to allow material to flow out of the gatebox, a hopper operable to direct material in the gatebox to the opening, a door coupled to the hopper and operable to move between an open position and a closed position by sliding along a surface of the gatebox, wherein the door comprises a front edge, a rear edge wider than the front edge, and at least two side edges that taper between the front edge and the rear edge, and a seal coupled to the hopper and operable to, when the door is in the closed position, engage the edges of the door and compress to prevent material in the gatebox from being released through the opening along the engaged edge of the door.
1. A gatebox for an aircraft, comprising:
an opening operable to allow material to flow out of the gatebox;
a hopper operable to direct material in the gatebox to the opening;
a door coupled to the hopper and operable to move between an open position and a closed position by sliding along a surface of the gatebox, wherein the door comprises:
a front edge;
a rear edge wider than the front edge; and
at least two side edges that taper between the front edge and the rear edge to create a liquid-tight seal when the door is in the closed position and reduce contact when the door is sliding; and
a seal comprising a raised lip along a side of the seal, the seal coupled to the hopper and operable to, when the door is in the closed position, engage one or more of the front edge, rear edge, or side edges of the door and compress to prevent material in the gatebox from being released through the opening along the one or more engaged edges of the door.
2. The gatebox of claim 1 , wherein the at least two side edges taper at an angle between 0°-5°.
3. The gatebox of claim 1 , wherein the door further comprises a raised lip along an edge of the door operable to compress the raised lip of the seal when the door is in the closed position to prevent material in the gatebox from being released through the opening.
4. The gatebox of claim 1 , further comprising a linear actuator coupled to the door and operable to move the door between the open position and the closed position along a linear axis.
5. The gatebox of claim 1 , wherein the seal is a liquid-tight seal.
6. The gatebox of claim 1 , wherein the door may move to a plurality of different open positions, wherein each open position exposes different amounts of the opening.
7. The gatebox of claim 1 , wherein the door comprises a plurality of doors.
8. The gatebox of claim 7 , wherein each of the plurality of doors are individually controllable.
9. The gatebox of claim 7 , wherein two or Chore of the plurality of doors are jointly controllable.
10. A system for distributing material from an aircraft, comprising:
a gatebox operable to affix to an aircraft comprising:
an opening operable to allow material to flow out of the gatebox;
a hopper operable to direct material in the gatebox to the opening;
a door coupled to the hopper and operable to move between an open position and a closed position by sliding along a surface of the gatebox, wherein the door comprises:
a front edge;
a rear edge wider than the front edge; and
at least two side edges that taper between the front edge and the rear edge to create a liquid-tight seal when the door is in the closed position and reduce contact when the door is sliding; and
a seal comprising a raised lip along a side of the seal, the seal coupled to the hopper and operable to, when the door is in the closed position, engage one or more of the front edge, rear edge, or side edges of the door and compress to prevent material in the gatebox from being released through the opening along the one or more engaged edge edges of the door.
11. The system of claim 10 , wherein the at least two side edges taper at an angle between 0°-5°.
12. The system of claim 10 , wherein the door further comprises a raised lip along an edge of the door operable to compress the raised lip of the seal when the door is in the closed position to prevent material in the gatebox from being released through the opening.
13. The system of claim 10 , further comprising a linear actuator coupled to the door and operable to move the door between the open position and the closed position along a linear axis.
14. The system of claim 10 , wherein the seal is a liquid-tight seal.
15. The system of claim 10 , wherein the door may move to a plurality of different open positions, wherein each open position exposes different amounts of the opening.
16. The system of claim 10 , wherein the door comprises a plurality of doors.
17. The system of claim 10 , wherein each of the plurality of doors are individually controllable.
18. The system of claim 10 , wherein two or more of the plurality of doors are jointly controllable.
