Abstract: The present invention provides a pot seedling feeding system for a transplanter, including a conveyor unit, a detection sensor, a controller, a seedling separation unit, side plates, and support stands. The conveyor unit includes a step motor, a transmission shaft, a conveyor belt, a tensioning shaft, and bearings. The seedling separation unit includes a seedling separation rod, a reset spring, a guide post, and a support seat. The controller is used to control the step motor which drives the conveyor belt in order to move the pot seedling. When a seedling receiving barrel of the planter rises to a seedling receiving position, the planter is controlled by using a brake cable, the seedling separation rod is then ejected which in turn drives the step motor to carry a pot seedling to move forward. The pot seedling is then dropped in a seedling receiving cup of the planter.

Abstract: An apparatus having an automatically adjustable pot seedling feed rate and a method therefor are provided. In some embodiments, the apparatus comprises a pot seedling scooper, a conveyance unit, a detection sensor, a controller, a seedling sorting unit, side panels, and brackets. The conveyance unit comprises a servomotor, a transmission shaft, a conveyor belt, a tension shaft, and a bearing. The seedling sorting unit comprises a seedling sorting rod, a reset spring, a guide post and a support seat.

Abstract: This present invention provides an automatic pot seedlings feeding mechanism for semi-automatic transplanter, comprising a transmission mechanism, a slider-crank mechanism, a stop lever, a side plate, a resetting mechanism and a bearing with bearing support. The transmission mechanism includes a transmission shaft I, a driving wheel, a transmission shaft II, a transmission shaft III and a conveyor belt. Under the performance of the conveyor belt, the pot seedlings are transported forward to the position of the stop lever. The slider-crank mechanism comprises a crank, a slider bar and a sliding chute, the crank and the driving wheel are connected through a revolute pair A, which is on the driving wheel, but not at the center of the driving wheel. The slider is securely connected with the resetting mechanism.

Abstract: Described is a high-speed transplanting mechanism that includes an angle-adjusting device about an angle of a duckbill entering soil, the mechanism comprising a rear arm, a front arm, a restoring spring, a control wire, a control wire sleeve and a control adjuster. The front arm is hinged on the mounting base of the planting device, the rear arm is hinged on the duckbill planting device, and the another end of the rear arm and the front arm are axial sliding connection. The control adjuster comprises an adjuster body and a handle fixed on the adjuster body. The restoring spring is positioned between the first limit plate on the rear arm and the second limit plate on the front arm. The end of the control wire is fixed on the second limit plate and, in turn, the other end of the control wire passes through the first limit plate, the restoring spring, the second limit plate and the control wire sleeve, and finally fixed to the adjuster body.

Abstract: The invention discloses a metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor, comprising a three-electrode system composed of a working electrode, a counter electrode, and a reference electrode. The surface of the working electrode is coated with a metal nanoparticles/nanocellulose composites. The surface of the nanocellulose is modified with a strong cationic conducting polymer. The invention promotes the sensitivity and selectivity of glucose sensing with the linear range of 4 ?M-15 mM and the detection limit of 1.4 ?M. Therefore, the sensor possesses high sensitivity, high response speed, stable performance and high anti-interference ability. The preparation method of the metal nanoparticles/nanocellulose composites-based non-enzymatic electrochemical glucose sensor is simple and the cost is low. And enzyme is introduced into the preparation process.
