Abstract: A multi-crop adaptive seed delivery and uniform seed distribution device, including: a seed storage box, a seed metering mechanism, a seed distributor lower housing, a seed distributor upper housing, and a blade driving mechanism. Closed accommodating cavity is formed between the seed distributor upper and lower housing; N seed guide tubes are arranged in circumferential direction, N being positive integer equal to or greater than 2; N blades are rotatably mounted in accommodating cavity; blades are arranged in vertical direction; closed independent seed guide cavity is divided in accommodating cavity by two adjacent blades; upper end of each seed guide tube is connected with corresponding seed guide cavity; top of seed distributor upper housing is divided into N fan-shaped areas in circumferential direction; upper end of each blade is connected to edge of corresponding fan-shaped area by means of elastic piece; and collision sensor is provided in each fan-shaped area.

Abstract: A perforating, oxygenating and water injection integrated apparatus for mushroom sticks of edible mushrooms includes a support component that can realize lifting motion; a perforating, oxygenating and water injection component includes a needle head fastener, the needle head fastener is connected to the support component via lifting pieces, a plurality of hollow needle heads are fastened to the needle head fastener, and the needle heads are respectively in communication with a water supply pipeline and an oxygen supply pipeline; mushroom stick support frames are installed on the support component, and can expand and contract relative to the support component; the mushroom stick support frames are located below the perforating, oxygenating and water injection component; and mushroom stick grabbing components are fastened to the support component, and includes grabbing mechanisms that grab the mushroom sticks to the mushroom stick support frames and then release.

Abstract: Disclosed is an unmanned vehicle suitable for mountains and hills and an attitude adjustment method, relating to the technical field of intelligent agricultural equipment in mountainous and hilly regions. The unmanned vehicle includes a frame and side arms arranged on both sides of the frame. The lower end of each side arm is provided with a traveling device, and each side arm is provided with an attitude adjustment device. The attitude adjustment devices are respectively connected to both sides of the frame, and the attitude adjustment devices are configured to adjust an attitude of the frame. The frame is provided with a control structure and a triaxial angle sensor, both of which are electrically connected to the control structure, and the triaxial angle sensor is configured to detect an angle of inclination of the frame. The unmanned vehicle can achieve the slope adaptation in the mountainous and hilly areas.
