The scraper is arranged on one side of the powder feeding end in the second direction. The first direction is perpendicular to the second direction. The scraper is provided with a blade part. The blade portion faces the powder spreading face in the first direction. The slag suction piece comprises a slag suction end. The slag suction opening is formed in the side, away from the scraper, of the powder feeding end in the second direction. And a slag suction opening is formed in the slag suction end. The slag suction opening faces the powder laying face in the first direction. The powder screening piece is communicated with the slag suction end and the powder feeding end. According to the powder spreading mechanism and the 3D printing device, the powder spreading operation efficiency can be maintained, meanwhile, the slag cleaning effect is improved, and powder is saved.

The utility model discloses a full-automatic cloth paving machine capable of paving and cutting cloth bidirectionally, which comprises a cloth paving machine body, a shearing device and a paving mechanism are arranged at the cloth paving end of the cloth paving machine body, the paving mechanism comprises a push rod, the push rod is positioned below the shearing device, a driving mechanism is arranged between the push rod and the cloth paving machine body, and the driving mechanism is positioned below the shearing device. During cloth paving, the fabric is cut off through the shearing device, the two ends of the paved fabric are prevented from arching and folding through stretching and retracting of the push rod, and the cloth paving quality is improved.

This invention discloses a fertilization device for the ecological cultivation of Chinese medicinal herbs, relating to the field of agricultural planting technology. It includes a spreading bucket, multiple discharge pipes at the bottom of the spreading bucket, valves on the discharge pipes, and an electric walking track at the bottom of the spreading bucket. A feeding rack is installed inside the spreading bucket, forming a semi-cylindrical storage space to hold fertilizer. Multiple through holes are located at the center of the arc-shaped surface of the feeding rack, directly below the discharge pipes. This invention allows the dispersing rack and separating plate to move laterally within the feeding rack, dispersing the fertilizer inside and effectively preventing fertilizer compaction. This ensures the fertilizer falls onto the soil surface after conforming to the specifications of the through holes, improving the quality of fertilizer application. Simultaneously, a rotating bending rod and a stirring rod can rotate along a path perpendicular to the lateral movement path of the dispersing rack, further agitating the fertilizer and improving the uniformity of fertilization.

The invention provides a throwing disc control method, a flight controller, a throwing disc dispenser and an aircraft, and relates to the technical field of aircrafts. The throwing disc control method comprises the following steps: acquiring rotation information of a throwing disc; calling a control instruction of the throwing disc according to the rotation information, wherein the control instruction is used for controlling the forward speed and the backward speed of the throwing disc to be equal; controlling the power source according to the control instruction. Therefore, the corresponding control instruction is obtained by obtaining the rotation information of the throwing disc, the power source is controlled according to the control instruction, and finally the rotation of the throwing disc is controlled by the power source, so that a control closed loop is formed, the control effect that the rotating speed of the throwing disc is stable is achieved, and finally the throwing disc swings at the speed equal to the returning speed in the past. And uniform material spreading is ensured, and the spreading quality is improved.

The invention relates to the technical field of additive manufacturing, aims to solve the technical problem that some known powder spreading mechanisms are difficult to give consideration to simple structure and improvement of powder spreading quality, and provides a powder spreading mechanism, additive manufacturing equipment and a powder spreading method. The powder spreading mechanism comprises a stock bin, a powder feeding roller, a driving part and a powder pressing roller. And the material bin is provided with a powder outlet. And the powder feeding roller is matched with the powder outlet. The driving piece is connected with the powder feeding roller and used for driving the powder feeding roller to rotate. The powder pressing roller is in transmission connection with the powder feeding roller through a transmission assembly and can be driven by the powder feeding roller to rotate. The powder spreading device has the beneficial effects that the simple structural design is considered, and the powder spreading quality of powder materials is guaranteed.

The invention relates to the technical field of pasture fertilization, and discloses an efficient fertilization device for pasture planting, the efficient fertilization device comprises a main body, the bottom of the main body is rotatably connected with a connecting shaft, and the left side and the right side of the connecting shaft are rotatably connected with moving wheels. When a rotating plate swings downwards, a sliding ring connected with the rotating plate pushes a sliding ring to slide downwards on the outer surface of an output shaft of a motor, when the sliding ring slides downwards, a spring is pulled to extend, potential energy is accumulated at the same time, and then when the motor is started, the rotating plate rotates in a small-amplitude conical state; therefore, the fertilizer is obliquely and downwards sown on the lawn, the sowing area of the fertilizer is reduced, small-amplitude sowing of a small amount of fertilizer is completed, the situation that when the small amount of fertilizer is sown in a small area, due to the fact that the rotating speed of the rotating plate is too high, the fertilizer is swung to be sown outwards, and the area becomes large is reduced, so that the fertilizer is sown more uniformly, and the sowing efficiency is improved. And the fertilizer spreading quality of the device during pasture planting is improved.
