Description

Technical Field

[0001] The invention relates to the field of purple yam horizontal cultivation, in particular to a purple yam planting machine. Background Art

[0002] Purple yam is also known as "purple ginseng". Its root tubers contain 1.5% protein, 14.4% carbohydrates, and a variety of vitamins and choline. It has high nutritional value. It is not only a delicacy on the table, but also a health-care medicine. It is a rare high-end food supplement and is widely loved.

[0003] At present, the cultivation of purple yam mainly consists of horizontal cultivation and vertical cultivation. Vertical cultivation is too dependent on manual labor, with high labor intensity, low production efficiency, and easy damage to the root tubers during harvesting. Horizontal cultivation, i.e. shallow trough horizontal cultivation technology, changes the original deep planting to shallow planting. Horizontal cultivation can grow purple yam that "grows horizontally". Purple yam grown through horizontal cultivation has a more glutinous taste, an amazing anthocyanin content, and is easy to harvest.

[0004] After searching, the current planting machines for Chinese yam / purple yam on the market include the following:

[0005] 1) Publication No. CN109673207A discloses a solar-powered yam planting machine, which includes a high-efficiency solar panel, a battery energy storage system, an energy management system, a brushless motor variable speed drive system, a crawler travel system, a steering wheel, a furrow opener, a line marker, a cover consisting of two sets of cover discs and cover arc plates, a frame and a workbench. The solar panel converts solar energy into electricity to drive the motor to rotate and drive the vehicle forward, and the battery is used to power the vehicle when the solar panel is insufficient. The steering wheel is used for turning the machine at the end of the field and steering on the field road. The furrow opener opens a groove, and the line marker draws lines in the opened groove according to a specific plant spacing for placing yam tubers. The cover covers the placed yam tubers to provide a good growth environment. The labor intensity and labor time of manual labor are greatly reduced.

[0006] 2) Publication No. CN112889378A discloses a yam planting mechanism of an intelligent agricultural machinery, including: a support plate, two first support rods are arranged at the bottom of the left side of the support plate, a first rotating shaft is arranged between the two first support rods, the first rotating shaft is rotatably connected with the first support rod, and rear wheels are arranged at both ends of the first rotating shaft, two second support rods are arranged at the bottom of the right side of the support plate, a second rotating shaft is arranged between the two second support rods, the second rotating shaft is rotatably connected with the second support rod, and front wheels are arranged at both ends of the second rotating shaft; a loosening assembly, the loosening assembly is arranged on the right side of the support plate; an interval digging assembly, the interval digging assembly is arranged between the front wheel and the rear wheel; an intelligent watering assembly, the intelligent watering assembly is arranged on the support plate. In the present invention, the interval digging assembly is adopted, which can ensure the planting spacing of yam seedlings, so that the yam seedlings are planted at equal spacing, improve the planting accuracy, and help to improve the utilization rate of land and save land resources.

[0007] 3) Publication No. CN119096755A discloses an automatic yam planting machine and a working method thereof. In the technical application, the machine comprises a frame, a wheel assembly is provided at the bottom of the frame, a planting module is symmetrically provided on the frame, and the planting module comprises a trenching mechanism, a placing mechanism, a vibration and pressure mechanism, a fertilizer spreading mechanism, a feeding mechanism and a soil covering mechanism arranged in sequence from front to back.

The present invention effectively solves the problem of heavy workload and low efficiency when planting yam in a shallow living groove.

[0008] Among them, the above-mentioned existing technologies 1 and 2 are both traditional yam planting machines, and existing technology 3 is to deal with the processes of grooving, placing shallow growing grooves, planting yam seed blocks, fertilizing and covering with soil in yam planting. Since the horizontal cultivation mode of purple yam is different from that of ordinary yam, the above-mentioned technologies do not meet the planting needs of purple yam. In addition, since the planting environment of purple yam is mostly mountainous, how to more efficiently dig trenches and turn grooves in mountain fields is also a technical problem that needs to be solved.
