The invention belongs to the technical field of coconut processing, and discloses a broken shell collecting device for coconuts in germinated coconuts. The broken shell collecting device for the coconuts in the germinated coconuts comprises a workbench, and supporting legs are welded to the four corners of the lower surface of the workbench. The four supporting legs are welded through reinforcingrods; a strip-shaped hole is formed in the middle of the workbench. The strip-shaped hole is formed inwards from the front face of the workbench and provided with an opening in the front face of the workbench, a guide plate is fixedly connected to the position, corresponding to the strip-shaped hole, of the lower surface of the workbench, the end, close to the front face of the workbench, of the guide plate inclines downwards, and the end, away from the front face of the workbench, of the guide plate is welded to the rear side of the strip-shaped hole. According to the shell breaking and collecting device for the coconuts in the germinated coconuts, through the arrangement of the shell breaking mechanism, spheroidic coconuts can be rapidly positioned and point to the centers of the coconuts for transverse shell opening, the broken shell collecting device is different from hole opening operation of traditional coconut shell opening equipment, and rapid discharging of the coconuts is facilitated through transverse opening.

The invention provides CVD equipment. The CVD equipment comprises a base, a grounding band and a fixing device, wherein the grounding band is connected between the base and the grounding end of the bottom of the equipment; at least one end of the grounding band is provided with connecting holes; the fixing device is suitable for being fixed to the base and / or the grounding end; the fixing device comprises a first fixture and a second fixture; the first fixture is provided with at least two locating columns; the grounding end is arranged on the locating columns through the connecting holes in apenetration mode; the second fixture is opposite to the first fixture; the second fixture is provided with at least two locating holes matched with the at least two locating columns; the locating columns and the locating holes are matched to clamp the end of the grounding band between the first fixture and the second fixture. The grounding band is located and installed through the locating columns and the locating holes. The installation time is reduced. Moreover, the CVD equipment is not prone to installation deviation during reinstallation after locating.

The invention disclose a double-hoist portal crane. The double-hoist portal crane comprises a hoisting main beam, the hoisting main beam is composed of a second hoisting beam plate and two first hoisting beam plates symmetrically installed at the two ends of the second hoisting beam plate, hoisting mechanisms are arranged on the two first hoisting beam plates, a driving part and a hoisting auxiliary beam are arranged inside the second hoisting beam plate, the driving part is located on one side of the hoisting auxiliary beam, baffles are arranged at the positions, close to the upper end and the lower end, of one side of the second hoisting beam plate correspondingly, one end, away from the driving part, of the hoisting auxiliary beam extends out of the baffles, the hoisting auxiliary beam is composed of a third hoisting beam plate and a fourth hoisting beam plate, the third hoisting beam plate is located at the upper end of the fourth hoisting beam plate, and first sliding grooves matched with the third hoisting beam plate are formed in the two end of the second hoisting beam plate correspondingly. The crane can operate within the range of a first span and a second span, and the problems that a conventional portal crane can only operate within one span during operation, and the operation range is small are solved.

The invention provides a refrigerator with a double-layer door structure. The refrigerator comprises a refrigerator body, an inner-layer door, an outer-layer door, a lighting device, a lighting switchand a transition piece, wherein a storage compartment is defined in the refrigerator body, the inner-layer door is connected to the refrigerator body in an open and closed mode, a through hole is formed in the position, close to the edge, of the inner-layer door, the outer-layer door is connected to the outer side of the inner-layer door in an open and closed mode, the inner-layer door and the outer-layer door can be opened and closed independently or together, the lighting device is used for lighting the storage compartment, the lighting switch is arranged on the part, making contact with the inner-layer door, of the refrigerator body, the contact point position of the lighting switch is opposite to the through hole, the transition piece is integrally arranged in the through hole in a penetrating mode, and the length of the transition piece is larger than the length of the through hole, so that the two ends of the transition piece can abut against contact points of the outer-layer door and the lighting switch correspondingly. According to the refrigerator with the double-layer door structure, the lighting switch is closed or opened by using a mechanical structure, the structure is simple, switch control components are reduced, and the control program of a circuit is simplified.

The invention relates to the technical field of decorative stone installation, and discloses a multifunctional frame for installing decorative stone on the wall, which includes a lower frame, the top of the lower frame is rotatably connected to an upper frame, and the upper frame is connected through a joint. The pages are rotatably connected to the top of the lower frame, both of the lower frame and the upper frame are in the shape of a "U", and the bottom of the upper frame is provided with a positioning and fixing device. The wall has a multifunctional frame for the installation of decorative stone materials. By making the rear side of the upper frame fit the front side of the lower frame, the positioning rod is moved backward, and the first fixing rod is rotated to the left. When the second After the vertical rod of a fixed rod is rotated out of the vertical groove of the first positioning groove, the overlapped lower frame and upper frame are fixed by the first fixed rod at the same time, so that workers can carry the device more conveniently, and at the same time The volume of the device is made smaller, so that when the device is stored, the occupied space is small.
