A working vehicle includes a traveling body supported by a traveling apparatus, a steeling portion that steers the traveling body, a lifting/lowering apparatus that lifts and lowers a working machine, and a controller configured to execute a turning control of setting a working machine descent start line in a coordinate system having a position of the traveling body at a start of turning as an origin, calculating coordinates of the traveling body based on a steering operation of the steering portion and a traveling distance of the traveling apparatus, and in a case where the traveling body has reached the working machine descent start line in a state in which the traveling body has completed the turning, starting lowering the working machine by the lifting/lowering apparatus.

The present disclosure relates to an onion growing method, and more particularly, to an onion growing method that includes the steps of: (a) allowing onions to be dormant; (b) breaking the dormancy of the onions; (c) planting the onions of which dormancy is broken in a field; (d) growing the planted onions to produce a plurality of stems and bulbs divided from the respective onions; and (e) harvesting the plurality of stems and bulbs. According to the present disclosure, the onion growing method does not have any limitation in growth time unlike a conventional onion growing method, reduces a period of growth, and drastically increasing onion yield to raise a farmer's profits. Also, the onion growing method stably supplies onion stems and leaves, thereby providing various profits through onions.

A method for conveying and dropping seedlings based on a device for conveying and positioning a seedling tray of an automatic transplanter, wherein the device for conveying and positioning the seedling tray of the automatic transplanter includes a platform for conveying the seedling tray, a first sensor, a second sensor, a plurality of push rods, and a control system. The platform is configured for conveying the seedling tray to be below seedling picking claws. The push rods are evenly distributed on the platform. The seedling tray is placed between adjacent two of the push rods. The first sensor is mounted close to the seedling picking claws and configured for identifying the seedling tray. The second sensor is mounted on a rack of the platform for conveying the seedling tray and configured for identifying the push rods. The control system controls the platform for conveying the seedling tray.

A transplanter including a frame structure that is configured to support a tray, an operating handle structure, and a base structure including a chute. The frame structure can include a furrower to from a furrow in soil and the transplanter can also include a furrow closing structure configured to close the furrow at a location beyond an end of the chute. The operating handle structure can enable one or more attributes of the operating handle to be selectively reconfigured. The base structure can be fabricated from one or more injection molded parts.

This invention belongs to a seedling separating device based on a rack and pinion drive in the field of transplanting machine in the agricultural automation facility, including a rack, a power unit, a linear drive, a number of seedling cups and a cylinder pushing device. The linear actuator is driven by the power unit to move on the frame; these seedling cups are mounted on the linear drive; the cylinder pushing device is mounted on the frame and is located behind the seedling cups and it drives the lower part of the seedling cup to open and retracts to close. The seedling device has simple structure, controllable program and high reliability. The motor drives the seedlings cups to move left and right; the cylinder pushes the cups to be opened and closed; the trust cup is straight down, the seedling attitude is better and the location of seedling can also be adjusted. The device can not only achieve the exact location in the designated seedling, but also to achieve the seedling movement of separating seedlings to two points from the mouth of the seedling cups.

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. In order to improve the quality of pot seedling planting, the seedling separation rod corrects a feeding posture of the pot seedling at the moment when the pot seedling drops. The present invention is about a mechanical seedling feeding system adopting the conveyor unit and the seedling separation unit that move intermittently, where multiple pot seedlings can be placed at a time, so that the operation is simple and fast, labor is saved and the cost is reduced. Stress from missing seedlings and excessive fatigue from repetitive movement are also eliminated from the implementation of this device.
