A heterogeneous multirotor configuration with a single main rotor and partially tilted multiple slave rotors.

ActiveCN121894201BControl rotor load is smallSmall rotor loadFlight vehicleClassical mechanics
This invention discloses a heterogeneous multi-rotor layout with a single main rotor and partially tilted multiple slave rotors, relating to the field of unmanned aerial vehicle (UAV) design technology. It includes a large main rotor providing primary lift and n control rotors arranged around it, with some control rotors mounted horizontally and the rest tilted at a fixed angle. During steady-state flight, the anti-torsional torque of the main rotor is statically balanced by the horizontal component torque of the pull force from the tilted slave rotors. Attitude control of the UAV is achieved by differentially adjusting the rotational speeds of the control rotors, including pitch control, roll control, and yaw control. Pitch and roll control are achieved by differentially adjusting the rotational speeds of symmetrically positioned control rotors, while yaw control is achieved by differentially adjusting the rotational speeds between the horizontally mounted and tilted control rotor groups. This invention achieves a fusion of high aerodynamic efficiency and easy operation, effectively improving the UAV's endurance and flight performance.

Gravel device based on granite aggregate and construction method

PendingCN121945211AThe process is smooth and hassle-freeavoid cloggingGrain treatmentsArchitectural engineeringCrushed stone
The invention discloses an aggregate stone crushing device based on granite, and relates to the technical field of granite crushing devices, the aggregate stone crushing device comprises a machine body bearing frame, and a granite crushing structure is arranged at the upper end of the machine body bearing frame. According to the granite aggregate and stone crushing device, in the rotating process of a conical sorting disc in a material separation structure, granite crushed aggregates meeting the particle size requirement are collected towards the center through the centrifugal effect, large materials are thrown to the edge, and through cooperation of an avoiding groove formed in the side wall of a sorting bin and a fixed top flow guide plate, the granite crushed aggregates meeting the particle size requirement are separated; and large materials can be effectively separated and guided out. More importantly, the central flow guide structure located in the middle forms a dynamic flow guide channel through the rotating central flow guide plate, falling materials are forcibly guided to be evenly dispersed, and the technical problem that in a traditional device, the materials are prone to accumulation and bridging in a bin, and consequently blockage is caused is thoroughly solved. And the process from feeding, pre-sorting to fed material crushing is ensured to be smooth and unobstructed.

Core processing strip coiling device

PendingCN122511738Aavoid bending damageQuality assurance
This invention relates to a magnetic core processing strip winding device, comprising a frame, a winding roller, a straightening roller, and a controller. The straightening roller includes a straightening plate and a support plate, and there are multiple straightening plates and support plates arranged in a ring array with a rotation axis as the rotation center line. The multiple straightening plates and support plates are enclosed to form a cylinder. The side of the multiple straightening plates and support plates opposite to the rotation axis abuts against the strip. The straightening plates are movably connected to the rotation axis. The controller is electrically connected to the straightening plates and is used to sense the position of the strip and control the movement of the straightening plates. This invention, through the combination of a ring array of straightening plates and support plates, in conjunction with a laser sensor and a controller, requires only one straightening roller to achieve precise dynamic straightening of the strip, avoiding bending damage caused by the strip repeatedly passing through multiple straightening rollers, and effectively ensuring the quality of brittle magnetic core strips.
