Description

Technical Field

[0001] This utility model relates to a crop cultivation device, and more specifically to a crop cultivation device with lifting and rotating functions. Background Technology

[0002] Statistics show that about 75% of people aged 60 to 70 in my country are still engaged in some form of farming, and this proportion is as high as 40% among those over 70. For many elderly people, agricultural labor is not only a habit but also a source of spiritual sustenance. However, chronic diseases such as arthritis and lumbar spondylitis are very common among the elderly, and repetitive bending and walking can greatly aggravate their conditions and even lead to accidents. As a result, various planting devices suitable for the elderly have appeared on the market, such as a lifting device for an orchid planting rack disclosed in Chinese patent (patent number 202020832529.0), which includes a base plate, guide sleeves, guide rods, a worktable, and a cylinder. Four guide sleeves are vertically welded to the top surface of the base plate, and the four guide sleeves are respectively located at the four corners of the base plate. Four guide rods are welded to the bottom surface of the worktable corresponding to the four guide sleeves, and the guide rods are inserted into the guide sleeves. A cylinder is also fixedly installed in the middle of the top surface of the base plate. The push rod of the cylinder points vertically upward, and a push head is connected to the top of the push rod. The push head abuts against the worktable but is not fixedly connected to it. When the worktable needs to be lowered, the push rod of the retracting cylinder can be used; conversely, the height of the worktable can be raised by extending the push rod. The worktable of the technical solution disclosed in this Chinese patent does not have a rotation function. When the worktable is too large, the farmer cannot stay in place to carry out planting and harvesting operations. Therefore, there is a need in the market for a cultivation device that allows farmers to plant and harvest in place. Utility Model Content
