This invention discloses a biomass pellet burner, comprising: a hopper including an inlet and an outlet; a screw feeder including a screw feed pipe, a screw feed rotating component disposed within the screw feed pipe, and a screw feed drive component connected to the screw feed rotating component, the outlet being disposed at a first end of the screw feed pipe; a combustion chamber disposed at a second end of the screw feed pipe; an air supply device including an air supply chamber and an air supply drive component connected to the air supply chamber, the air supply chamber including an air distribution chamber and a combustion chamber air chamber, the air distribution chamber communicating with the screw feed pipe, and the combustion chamber air chamber communicating with the combustion chamber; and an ignition device, a sealing plate disposed between the air distribution chamber and the combustion chamber, the inlet end of the ignition device being located within the air distribution chamber, and the outlet end of the ignition device being located within the combustion chamber. This invention avoids backflow and backfire by balancing the pressure of the screw feed pipe and the combustion chamber.

The utility model provides a source network load storage integrated energy storage cabinet which comprises a cabinet body, a cabinet door, a battery support, a battery box and an electrical assembly, and a battery cavity and an electrical cavity are formed in the cabinet body. A plurality of layers of bearing units are arranged on the battery bracket from top to bottom, accommodating grooves are formed in the bearing units, rolling bodies are arranged at the bottom of the battery box, and the rolling bodies protrude out of the bottom surface of the battery box. According to the utility model, the accommodating groove is formed in the battery bracket, the rolling body is arranged at the bottom of the battery box, and the height of the rolling body protruding out of the bottom surface of the battery box is smaller than the depth of the accommodating groove, so that the contact area between the battery box and the bearing unit can be reduced when the battery box is mounted, the pushing resistance is reduced, and the battery box is easier to mount in place; and no scratch is generated at the bottom of the battery box. And after the battery box is mounted in place, the rolling body is suspended in the accommodating groove and cannot be damaged after being used for a long time.

The utility model discloses a handheld dust collector floor brush shell with a damping function, and relates to the technical field of handheld dust collector floor brush shells, the handheld dust collector floor brush shell with the damping function comprises a handheld dust collection device, and the bottom of the handheld dust collection device is provided with a floor brush device; according to the utility model, the plurality of shock absorbers are arranged between the bottom of the shell and the floor brush device, so that the shock generated when the floor brush device works on different grounds can be effectively absorbed, the transfer of the shock to a handheld part is reduced, the dust collection process is more stable, the holding comfort of a user is improved, and meanwhile, the abrasion of internal parts caused by the shock is reduced; the product service life is prolonged; the second motor drives the rolling brush to rotate at a high speed, and dust, sundries and the like on the ground can be efficiently cleaned in cooperation with suction force formed by the dust suction nozzle and the dust suction pipe; the observation window is convenient for a user to know the working state of the rolling brush in real time, discover problems and clean in time, and ensure that the cleaning effect is always kept good.

The utility model relates to the technical field of weeding machine, and disclose a sterilization insecticidal weeding machine, including the car body, the car body top fixedly connected with engine, the car body top one side fixedly connected with handlebar. The utility model discloses through the integration pesticide spraying subassembly and the grass cutting subassembly, realized the multifunctional integration operation of weeding, sterilization, insecticidal, specifically, the design of the stirring rod in the medicine cartridge ensures that the liquid medicine mixes evenly, and the water pump and the spray head can be sprayed to the weed and the soil surface with the sterilizing agent or the insecticide accurately, effectively kill the hidden pest and pathogenic microorganism, avoid the problem that the traditional weeding machine only cuts the grass but leaves the pest problem, at the same time, the rotary blade of bottom grass cutting subassembly and the grass board synergistic effect, not only efficient cutting weeds, but also can gather the cut weeds to the car body both sides automatically, prevent the weeds from accumulating on the operator's path, significantly reduce the pushing resistance, improve the operation smoothness and work efficiency.

The invention relates to a docking assembly mechanism for a large battery pack in a cabin. The docking assembly mechanism comprises a module grouping assembly, a battery pack placing trolley, an auxiliary adjusting assembly and a cabin docking assembly, the module grouping assembly is used for forming a battery pack by a plurality of battery modules; the battery pack placing trolley comprises a main beam frame, and a roller guide rail group, a baffle plate assembly and a walking assembly which are arranged on the main beam frame; the roller guide rail group is used for bearing and transferring battery packs; the baffle assembly is used for limiting the battery pack on the roller guide rail group; the auxiliary adjusting assembly is arranged between the roller guide rail set and the main beam frame, and the roller guide rail set evenly supports the battery pack by adjusting the height of the auxiliary adjusting assembly. The in-cabin butt joint assembly is arranged in the energy cabin; the butt joint guide rail group is used for being in butt joint with the roller guide rail group and guiding the battery pack into the energy cabin; and the butt-joint bolt hole seat is used for being matched with a bolt arranged on the battery pack to limit the battery pack on the butt-joint guide rail group. The device is reliable in structure and convenient to operate, and rapid and safe assembly of the large battery pack is achieved.
