A cover system is disclosed that comprises at least one cover sheet having four edges; a plurality of flexible rafters, each of the rafters is slidably connected to at least one of two opposite edges of the four edges; and at least one roller provided on at least one of two other opposite edges of the four edges, wherein the roller is configured to rotate, and the cover sheet is configured to wrap around the roller and be released from the roller, depending on a direction of rotation of the roller.

A mobile trellis may be expandable and/or may include reusable components (i.e., components that are used with a second plant following use of the mobile trellis/component with a first plant). A mobile trellis may be incorporated into a horticultural environment. An expandable mobile trellis may include modular components. A mobile trellis may create a microclimate for an associated plant. A mobile trellis may anticipate changes in an associated horticultural environment based upon an event (e.g., a door opening, a component failure, etc.) and/or the mobile trellis may preemptively alter an “input” to, and/or an “output” from, a horticultural environment based on anticipating a change in the horticultural environment.

A container gardening structure has a grow tray with multiple growing stations that extend a radially from a central point of the grow tray. A light fixture has multiple lighting elements disposed above the grow tray to radiate light to the grow tray and extending outwardly from a central axis for the light fixture, with the central axis extending upward from the grow tray through the grow tray central point, and the lighting elements extend along the light fixture such that a distance from lighting elements to the grow tray increases in length from a lowest lighting element to a highest lighting element. The light fixture and grow tray move relative to each other such that the growing stations are moved away from lights that are disposed closer to the grow tray and toward lights that are disposed further from the grow tray.

An object handling system is described, the system having two substantially perpendicular sets of rails forming a grid above a workspace, the workspace having a plurality of stacked containers. The system includes a series of robotic load handling devices operating on the grid above the workspace, the load handling devices having a body mounted on wheels. The robotic devices can move around the grid under instruction from a computing device, the robotic devices being moved to a point on the grid above a stack of containers and then, using a lifting device, engage and lift a container from the stack. The container is then moved to a point where the objects in the container can be accessed. Modifications to the workspace and grid are described that allow vehicles and roll cages to be used to move stacks from the workspace to a point outside the workspace or from outside the workspace into the workspace.

Illustrative configurations of greenhouse shading systems are disclosed. One illustrative system includes a plurality of main trusses supporting a translucent material defining an interior space, a plurality of gantries; and a plurality of shades attached to the gantries and the main trusses. The main trusses, gantries, and shades cooperate to move the shades between a closed position and an open position thereby regulating the amount of light the entering interior space of the greenhouse.

A plant cultivation facility includes multiple cultivation racks, each of the cultivation racks including multiple shelves for cultivating plants and a pair of closed sides extending in a longitudinal direction, the shelves each forming a tube inner space extending in the longitudinal direction. Each shelf includes an air inlet formed as an opening on one end of the tube inner space and an air outlet formed as an opening on the other end. The plant cultivation facility further includes: a cultivation room containing the cultivation racks; an air-conditioning room separated from the cultivation room; an air-conditioning device positioned in the air-conditioning room for sucking air from the cultivation racks through the air outlets into the air-conditioning room; and a discharge pipe positioned in the air-conditioning room, the discharge pipe being connected to the air-conditioning device for forwarding air from the air-conditioning room to be released into the cultivation room.

The present invention discloses a spliced small arch shed frame, applying to the technical field of agricultural equipment. The arch pole, the transverse connecting pole and the longitudinal connecting pole of the small arch shed are all connected by a number of supporting hoops and a number of double-ended connectors; two transverse connecting poles and two longitudinal connecting poles are connected end to end together to form a rectangular base support structure; a plurality of mutually parallel arch poles are arranged between the two transverse connecting poles; all arch poles are located above the base support structure and together constitute the arch support structure; the fixed pole is set on the top of the arch support structure, and is connected with each arch pole in the arch support structure through two fixed ends of the bi-directional clip, so that all arch poles are connected as a whole

A greenhouse comprises a support frame and a spray pipe including pipes and pipe joints, the pipe joint comprises a connecting pipe and two rotary sleeves, the two adjacent pipes are respectively inserted into the connecting pipe, ends of a first pipe are respectively sleeved with a sealing sleeve and a locking sleeve, and each of the ends of the first pipe is further sleeved with a washer. When the rotary sleeve is thread-tightened, the connecting pipe and the locking sleeve are capable of respectively abutting and pressing against two sides of the washer, under abutting and pushing of the rotary sleeve and limiting of the washer, the locking sleeve is capable of grasping the first pipe and forming an axial positioning with the rotary sleeve. An inner edge of an end surface of the connecting pipe has a sealing tapered surface capable of acting on the sealing sleeve.
