The utility model discloses a material pushing device for edible mushroom production, which comprises a box body, the top of the box body is connected with a shell in a penetrating manner, a sleeve is sleeved in the shell and close to the bottom, an inner gear ring is movably connected in the sleeve through a bearing, the top of the inner gear ring is connected with a butt joint pipe through a bolt, and the butt joint pipe is connected with the bottom of the box body through a bolt. The butt joint pipe penetrates through an inner ring of the bearing and extends to the position above the shell, the top of the butt joint pipe is closed, a feeding pipe is arranged in the butt joint pipe in a sleeved mode, and a plurality of evenly-distributed fan-shaped baffles are slidably connected to the bottom of the sleeve. According to the technical scheme, through mutual cooperation of an inner gear ring, a small gear, a rack plate, a fan-shaped baffle and other components, the hole diameter of a sleeve can be conveniently adjusted, so that the edible mushroom bagging device can adapt to bagging of edible mushrooms of different sizes, the application range and the use efficiency of the edible mushroom bagging device are improved, quantitative material pushing can be achieved, and the practicability is high. Therefore, the edible mushrooms are not easy to overflow, and the pushing efficiency and the bagging efficiency are improved.

This invention provides an outdoor energy storage battery cabinet, relating to the field of energy storage equipment technology. It includes a housing, a first elastic rope, a second elastic rope, and a tensioning assembly. The housing has a receiving cavity for accommodating the energy storage battery and a heat dissipation window communicating with the receiving cavity. Both the first and second elastic ropes are slidably connected to the housing and are retractable. The first and second elastic ropes are arranged crosswise at the heat dissipation window to divide the window into multiple heat dissipation holes. The tensioning assembly is connected to at least one of the first and second elastic ropes and can push and pull the first and / or second elastic ropes to extend or shorten them, thereby adjusting the diameter of the heat dissipation holes. This invention can dynamically adjust the heat dissipation capacity according to the battery's operating state and environmental conditions, solving the technical defects of fixed heat dissipation schemes such as unadjustable heat dissipation and poor environmental adaptability, thereby improving the operational safety and environmental adaptability of the energy storage system.

This utility model provides a high-sealing junction box, belonging to the technical field of junction boxes. It includes a base plate, with two symmetrically fixed vertical sidewalls on both sides of the front of the base plate. A C-shaped frame is horizontally slidably installed between the two sidewalls, forming a box structure. Circular perforations are installed in the middle of the upper and lower ends of the C-shaped frame. Several arc-shaped blades are movably installed in the center of the perforations. A limiting bracket for retracting the arc-shaped blades is rotatably installed in the center of the perforations, forming a camera aperture structure. A sealing sleeve for fitting onto the cable is fitted at the opening of the perforations. The arc-shaped blades retract and abut against the outer edge of the sealing sleeve to form a seal. This utility model is flexible and convenient to use, can adapt to the sealing installation of cables of different specifications, and has good overall performance.

The utility model relates to the technical field of plastic recycling, and particularly discloses a plastic screening and recycling device which comprises a discharging frame, a vibration motor, two sets of screening frames and screening plates arranged in the screening frames, the bottoms of the screening plates are connected with baffles in a sliding mode, and adjusting assemblies used for adjusting the baffles to slide are arranged on the screening frames. By arranging the sieve plate, the baffle, the fixing block, the threaded rod, the sliding piece and the limiting piece, when the threaded rod is rotated, the fixing block drives the baffle to translate in the guide direction of the sliding piece, meanwhile, the limiting piece ensures the rotation positioning accuracy of the threaded rod, and by adjusting the relative position of the baffle and the sieve plate, the hole diameters of the baffle and the sieve plate are staggered; by means of the design, accurate adjustment can be conducted according to the processing requirements of plastic particles with different particle sizes, the adaptability of the production process is guaranteed, and the production efficiency and practicability are remarkably improved.
