Description

Special adjustable degree of depth device that loosens soil is planted to chinese-medicinal material Technical Field The invention relates to the technical field related to Chinese medicinal material planting, in particular to a special depth-adjustable soil loosening device for Chinese medicinal material planting. Background In the field of Chinese medicinal material planting, soil loosening is a key link for ensuring the development and quality of medicinal material root systems. Currently, commonly adopted scarifiers mainly comprise a hand-held or traction rotary cultivator, a micro plow, a hoe and the like. The basic working flow is that a tractor or a man power is used for providing traction power to drive a frame provided with a fixed rotary tillage cutter or a plowshare to travel in the field, and the soil is crushed by utilizing continuous rotary cutting of the cutter or continuous upturned soil effect of the plowshare. The core structure of these devices is typically a simple frame to which non-adjustable tillage elements are mounted either directly or by bolts. The main function of such devices is to finish the turning and coarse breaking of the soil, aimed at preparing the seedbed for sowing or transplanting. However, the existing soil loosening tools and equipment have significant defects in meeting the requirements of fine planting of traditional Chinese medicinal materials. Firstly, the cultivation depth is very inconvenient to adjust, most of the cultivation depth is realized by replacing cutters with different specifications or adjusting the height of the whole machine frame, the adjustment process is rough and can not realize stepless fine adjustment in operation, and the specific requirements of different medicinal materials (such as fritillary bulbs with shallow roots and astragalus with deep roots) on the depth of rhizosphere soil are difficult to be accurately adapted. Secondly, the traditional continuous rotary cutting operation mode has good efficiency, but has great damage to the soil structure, is easy to form a new plough bottom layer and excessively disturb the beneficial microorganism environment, and does not accord with the ecological planting concept of Chinese medicinal materials. Most importantly, when facing hard soil hardening, the existing equipment lacks an effective local reinforcement breakthrough mechanism, so that the problems of uneven cultivation depth, rapid cutter abrasion and even power overload shutdown often occur, and the deep soil can not be effectively loosened while the surface vegetation is protected. These defects restrict the further improvement of the yield and quality of the Chinese medicinal materials. In order to solve the problems, a special depth-adjustable soil loosening device for planting Chinese medicinal materials is provided. Disclosure of Invention The invention aims to provide a special depth-adjustable soil loosening device for planting traditional Chinese medicinal materials, which aims to solve the problems that in the background art, the conventional soil loosening device for planting traditional Chinese medicinal materials is inconvenient in cultivation depth adjustment, cannot adapt to different medicinal material requirements, and is lack of an effective local reinforcement mechanism when facing hardened soil, so that uneven soil crushing, easy damage to cutters or overload of equipment are caused, and the soil overall structure is high in destructiveness and difficult to meet the requirement of fine planting. The special depth-adjustable soil loosening device for planting Chinese medicinal materials comprises a frame, wherein one end of the frame is provided with a soil loosening mechanism, the soil loosening mechanism comprises a cabinet, a cutter and a baffle, the lower end of the cabinet is fixedly connected with the baffle, the cutter is of a rake-shaped structure with a plurality of sharp teeth and is slidably arranged in an inner cavity of the cabinet, and the working end of the cutter extends out of an opening preset in the bottom of the cabinet and is used for executing soil loosening operation; A hammering mechanism is arranged in the frame, the output end of the hammering mechanism is positioned above the cabinet and is used for applying vertical downward impact force to the upper end face of the cabinet, so that the whole cabinet and a cutter inside the cabinet are driven to move downwards instantly, and the part of the cutter extending out of the cabinet can forcedly penetrate and crush soil at a set depth. In a further embodiment, the tool comprises a tool rest, a screw and a limiting rod, wherein the tool rest is slidably mounted in the cabinet, the lower end of the tool rest extends out of a preset opening in the bottom of the cabinet, the screw is rotatably mounted at the upper end of the tool rest, the screw is in threaded connection with the cabinet, the limiting rod is fixedly connected at the upper end of the to
