Description

Garden management machine with accurate degree of depth regulatory function Technical Field The invention relates to the technical field of field management machines, in particular to a field management machine with an accurate depth adjusting function. Background The field management machine, commonly called as a multifunctional management machine, a mini-tiller or a gardening tractor, is mainly used for 'field', namely, a working space where large machines such as a greenhouse, an orchard, vegetable fields, hilly and mountain areas and small lands are difficult to enter or spread. The most commonly used functions of the field management machine are rotary tillage, soil crushing and stubble burying, for the depth of rotary tillage, the proper depth can provide loose, breathable, water-retaining and fertilizer-retaining soil environment for the root system of crops, meanwhile, the soil environment can also effectively cover the residual stubble and weeds of the previous stubble crops, plant diseases and insect pest sources are reduced, if the depth is too shallow, the nutrient layer is thin, the crops are easy to lodge and decline early, the soil bottom layer can form a hard plow bottom layer to prevent water fertilizer from penetrating down and root system from pricking down, if the depth is too deep, the bottom layer raw soil can be turned up to be unfavorable for seedling growth, and the larger the load of a rotary tillage machine is, the higher the oil consumption is, the operation speed is slower, at present, according to the cultivation experience, the rotary tillage depth is generally controlled to be 12-18 cm for the conventional field crops, the rotary tillage depth is generally controlled to be 15-20 cm for vegetables, the rotary tillage depth is generally controlled to be 8-12 cm for fruit tree tea gardens, and the root system is generally controlled to be 20-25 cm for planting crops. Through retrieval, chinese patent application number 202210273430.5 discloses an unmanned field management machine, which belongs to the field of agricultural machinery and comprises a frame, a rotary tillage main body and a camera component, wherein the rotary tillage main body is arranged below the frame, the camera component is arranged above the frame and comprises a camera frame body, a camera support rod, a horizontal driving component for controlling the camera support rod to rotate along the horizontal direction and a vertical driving component for controlling the camera support rod to rotate along the vertical direction, the camera frame body is fixedly arranged at the front end above the frame, the horizontal driving component is fixedly arranged on the camera frame body, the vertical driving component is fixedly arranged on the horizontal driving component, and one end of the camera support rod is arranged at the output end of the vertical driving component. Through the above search, it can be known that the field management machine generally controls the rotary tillage depth by changing the length of the blade, but changing the blade according to the situation increases labor intensity, and meanwhile, even if the blade is changed to a proper length, the rotary tillage depth is inconsistent due to the conditions of inclination, jolt and the like in the moving process of the field management machine. In order to ensure that the rural area management machine can accurately adjust rotary tillage depth, the technical scheme is that the rural area management machine has an accurate depth adjusting function.
