This utility model relates to the field of cleaning equipment technology and discloses a suction-type leaf shredder, including a suction frame body with two suction nozzles. From bottom to top, each suction nozzle has a shredding mechanism, a fine shredding mechanism, a flow guiding mechanism, and an anti-fall mechanism. The shredding mechanism includes a gear motor mounted on the outside of the suction nozzle. A cutter shaft is fixedly connected to the output end of the gear motor, and the end of the cutter shaft away from the gear motor is rotatably connected to the inner wall of the suction nozzle. Multiple cutter sleeves are arranged on the outside of the cutter shaft. Through the cooperation of a compression plate and the shredding mechanism, the leaves are pre-compressed after being sucked in, effectively reducing the leaf volume and providing a more compact leaf accumulation for the subsequent shredding process. This avoids low shredding efficiency due to loose leaf volume, ensuring preliminary shaping and compaction of the leaves before entering the shredding area, and significantly improving shredding efficiency.

The utility model discloses a gummed paper compression roller convenient to adjust, which comprises a base, a lower rotating roller is rotatably arranged on the inner side of the base in a positioning manner, an upper rotating roller is arranged above the lower rotating roller in an attached manner, and two ends of the upper rotating roller are longitudinally and slidably connected with the base through longitudinal elastic reset sliding components. According to the rolling device, the upper rotating roller capable of longitudinally sliding is designed, so that the gap between the upper rotating roller and the lower rotating roller is adjustable, the rolling device can be suitable for rolling base material layers with different thicknesses, and the upper rotating roller is matched with the telescopic spring, so that the base material layers can be compacted and the rolling effect can be ensured when the base materials with different thicknesses are rolled; in addition, a tensioning wheel assembly is designed, under the condition that the upper rotating roller is adjusted up and down, it can be guaranteed that the transmission belt between the belt gear A and the belt gear B is always in a tightened state, and the situation that the upper rotating roller and the lower rotating roller cannot rotate synchronously due to loosening of the transmission belt is avoided.

The utility model discloses a wood board hot press, which relates to the technical field of wood board hot presses, and comprises a hot press main body, a plurality of groups of placing plates are elastically and movably arranged in the hot press main body, and limiting mechanisms are movably arranged at the left end and the right end of the top of each group of placing plates. An upper fixing plate is elastically and movably installed on the lower fixing plate, a plurality of sets of lower limiting baffles are fixedly installed at the top end of the lower fixing plate, a plurality of sets of upper limiting baffles are fixedly installed at the bottom end of the upper fixing plate, and the lower limiting baffles and the upper limiting baffles are arranged in a staggered mode. According to the design scheme, through the design that the upper fixing plate is elastically and movably installed on the lower fixing plate, the upper fixing plate can be extruded downwards along with the plate, so that the plate is compacted, when the plate is placed, the height of the upper fixing plate can be larger than the thickness of the plate, the plates of various thicknesses can be machined, and the machining efficiency is improved. And the universality of the equipment is improved.

The utility model discloses a kind of for asphalt pavement pit slot's quick repairing device, including storage bin, walking wheel being set in the bottom of the storage bin and setting in the blanking port of storage bin lower end, the blanking port is strip hole, the bottom of storage bin is symmetrically equipped with the baffle that the bottom of storage bin is same direction or reverse synchronous movement, heating plate is equipped with in the bottom of storage bin behind blanking port position adjustment baffle position according to the size of asphalt pavement pit slot, so that the length exposed with blanking port corresponds with the size of pit slot, application range is wide, then moves storage bin, and asphalt in storage bin is spread to asphalt pavement pit slot through blanking port, and is ironed flat by heating plate. Pit slot mechanization spreading and leveling can be realized, and spreading efficiency is improved;It can effectively improve the flatness of pit slot repair, and compaction under the condition of guaranteeing mixture temperature.
