This application relates to a harvester ladder and a harvester, belonging to the field of agricultural equipment technology, to optimize the structure of the harvester ladder to a certain extent, simplify the transmission structure, and reduce manufacturing and maintenance costs. The harvester ladder provided by this utility model includes a ladder assembly, a drive assembly, and a positioning assembly; one end of the drive assembly is rotatably connected to the positioning assembly, and the other end is rotatably connected to the side of the ladder assembly; the ladder assembly has a docking part, the positioning assembly has a positioning part, and the docking part and the positioning part are rotatably connected; the drive assembly includes a telescopic drive component, and the extension and retraction of the telescopic drive component can drive the ladder assembly to rotate relative to the positioning assembly.

The utility model discloses a kind of air duct machines, air duct machine includes: cabinet, air inlet and air outlet are formed on two sides of each other of cabinet, and cabinet has bottom plate;Heat exchanger;Fan assembly;Water pan, water pan is located in the lower of heat exchanger in cabinet;First flexible seal, first flexible seal is located between water pan and bottom plate, to fill the gap between water pan and bottom plate;At least one of water pan and bottom plate is equipped with convex rib, convex rib extends along the width direction of air duct machine, and convex rib protrudes from the side of bottom plate and / or water pan towards first flexible seal. According to the air duct machine of the utility model embodiment, the first flexible seal is extruded by convex rib, the sealing between water pan and / or bottom plate and first flexible seal can be improved, and then low-temperature air can be effectively prevented from entering between water pan and bottom plate, to avoid condensate between water pan and bottom plate.

The utility model provides a kind of multi-station fine adjustment fixer structure, to hold multiple miniature workpieces to carry out processing, it includes: a first movable block, is equipped with a first bevel surface in its first body;A second movable block, is equipped with a first bevel surface in its second body;Two combined elastic components, are set between two first ear blocks and two second ear blocks, so that the first bevel surface and the second bevel surface form a forced slot;And a wedge, is placed in the forced slot, and the wedge is equipped with a combination hole to provide a combination bolt;By the combination bolt being combined on processing platform, and the combination bolt is rotated to let the wedge be displaced downward to force the forced slot, to facilitate the first movable block or / and the second movable block to hold and fix miniature workpiece.

The application provides a disposable brewing aluminum foil capsule, which comprises a cup body, a liquid outlet, a filter assembly, non-woven fabric, a liquid inlet hole, a supporting plate, a filter piece, an elastic vertical plate, a first filter gap, an elastic opening piece and a pressure bearing plate. When the extraction pressure increases, the pressure bearing plate will move and drive the elastic opening piece to move downward. The downward movement of the elastic opening piece will drive the end of the elastic vertical plate away from the supporting plate to open outward, so as to increase the width size of the first filter gap, and then prevent the over-extraction phenomenon such as bitter taste caused by excessive pressure of the extraction liquid due to small aperture when high-pressure extraction occurs. When the extraction pressure is small, the elastic vertical plate will reset under the elastic action of itself, so as to reduce the width size of the first filter gap and prevent the problems of insufficient extraction and poor taste caused by the fact that the coffee powder cannot fully contact the extraction liquid when a large-aperture capsule is used in a low-pressure device.
