The invention provides a vibrating fruit tree harvester and belongs to the technical field of orchard harvesting. The vibrating fruit tree harvester comprises a frame, an internally spherical pull bar a, an externally spherical shaft sleeve a, an L-shaped rocking bar, an internally spherical pull bar b, an externally spherical shaft sleeve b, a connecting bar, an eccentric wheel, a power input shaft, a steel wire rope, a hook and the like. The frame is fixed to the rear of a tractor. The power input shaft is fixed on the frame. The other end of the power input shaft is connected with the eccentric wheel. The eccentric wheel is hinged to the L-shaped rocking bar through the connecting bar. The steel wire rope is suspended to the left end of the L-shaped rocking bar, and the hook is arranged at the other end of the steel wire rope. A power output shaft of the tractor drives the eccentric wheel to rotate, and the eccentric wheel transmits power to the L-shaped rocking bar so that the L-shaped rocking bar swings left and right to drive a trunk hooked by the steel wire rope and the hook to vibrate so as to shake off fruits. The vibration amplitude and vibration frequency of the steel wire rope acting on the trunk are adjustable. The vibrating fruit tree harvester is applicable to harvesting fruits on various fruit trees. The length of the steel wire rope is adjustable, and accordingly the vibrating fruit tree harvester is applicable to mechanical harvesting of tree fruits planted in any mode.

The invention provides a rice direct seeding high yield planting technology, which comprising the following steps: choosing the land without industrial 'three wastes', namely, waste gas, waste water and industrial residue as the cultivation land; applying enough organic fertilizer; choosing disease-resistant varieties; applying rice direct seeding technology; reasonably providing inorganic fertilizers and pesticides to ensure high yield of mature rice. The invention has the beneficial effect that the application of the invention in rice production guarantees high and stable yield of rice and income improvement of farmers.

The invention discloses a picking method and picking robot device aiming at fruits which are in size of an apple and is similar to a sphere. The picking robot device comprises a mechanical actuating device, control system hardware and control system software. The mechanical actuating device comprises a picking mechanical arm, an underactuated manipulator, an electric sliding table and an intelligent mobile platform, wherein the control system hardware comprises an IPC (industrial personal computer), a motion control card, a data acquisition card, an AHRS (attitude and heading reference system), a coder, a monocular camera, a binocular camera, a force sensor, a slipping sensor and the like. During operation, the IPC fuses information of the coder, the AHRS, monocular camera components and an ultrasonic sensor to enable the mobile platform to independently navigate and avoid obstacles. A binocular vision system collects images of mature fruits and obstacles and extracts the characteristics of the images so as to realize obstacle avoidance of the mechanical arm and fruit positioning. Finally, the IPC fuses the information of the force sensor, the slipping sensor and the position sensor, thereby further reliably gripping the mature fruits and separating the fruits from fruit branches.

The invention relates to a tobacco maturity detection method and device. The tobacco maturity detection method comprises the steps of: acquiring an image of tobacco to be detected by an image acquiring unit, processing the image to establish or convert into an image with an HSV (Hue Saturation Value) color mode, obtaining an H color component value and an S color component value of the image; and figuring the maturity grade MD of the tobacco to be detected according to a given mathematical model. The tobacco maturity detection method and device are used for judging the maturity of the tobacco through the acquired tobacco image, and have the advantage of field rapid, site and living nondestructive detection to ensure visual and quantitative judgment of the maturity of the tobacco and strong operability, and are beneficial to proper harvesting and improving of homogeneity and tobacco quality of initially baked tobacco. In the method, model parameters are judged by using the H color component value and the S color component value in an image HSV color model without the V color component value, therefore, the influence of the value of the image to the establishment of the model is eliminated.

The invention relates to a multi-spindle mechanized machine for harvesting caragana korshinskii seeds. The multi-spindle caragana korshinskii seed collecting and harvesting machine comprises a rack, a plurality of spindles rotatably supported on the rack, collection devices fixed to the spindles, a drive mechanism for driving the spindle to rotate and fruit pod and seed conveying devices. The spindles located on the left half portion of the rack is symmetrical to the spindle located on the right half portion of the rack, the collection devices are the same as the spindles in number, the conveying devices are arranged in a left-right mode, and the collection devices are in left-right symmetry to the conveying devices. The power is from a traction machine or an independent engine, the walking mode can be either a traction mode or a self-walking mode, the machine can ride on a caragana korshinskii plant when working, collecting and harvesting of one line of caragana korshinskii seeds / fruit pods can be completed one time at a minimum, and thus collecting and harvesting efficiency can be doubled; meanwhile, mechanized collecting and harvesting work of seeds of high-plant type caragana korshinskii such as white caragana korshinskii can be further conducted, and the problems that the collecting and harvesting link of caragana korshinskii seeds is low in efficiency and high in cost are solved.
