DETAILED DESCRIPTION

[0045] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0046] The present invention discloses a comprehensive treatment method for the continuous cropping obstacle of Coptis chinensis. Figure 1 As shown, the following steps are included:

[0047] Step 1. Level the soil to be sown after continuous cropping and remove weeds and gravel;

[0048] Step 2. Install the frame 100 equipped with multiple excavation type slope forming mechanisms 300 on the agricultural machine;

[0049] Step 3. Control the agricultural machine to move forward, and at the same time drive each excavation type slope forming mechanism 300 to rotate, so that each excavation type slope forming mechanism 300 digs a ditch in the soil, and a trapezoidal slope is formed between two adjacent excavation type slope forming mechanisms 300;

[0050] Step 4. In the process of driving the excavation type slope forming mechanism 300 to rotate, the liquid soil repair agent is sprayed into the rotary excavated soil, so that the soil repair agent is mixed with the rotary excavated soil;

[0051] Step 5. After 8-11 days, sow the seeds or seedlings of Coptis chinensis on the two sides of the trapezoidal slope;

[0052] Step 6. When summer comes, build a sunshade net in the planting field to shade the growing Coptis chinensis seedlings;

[0053] Step 7. Carry out corresponding field management according to the change of seasons and growth cycles, such as spraying pesticides, clearing weeds, spraying nutrient solution or watering;

[0054] Step 8. Until the Coptis chinensis is harvested, the seeds of the Coptis chinensis can be harvested, and the rhizomes of the Coptis chinensis can be harvested at the same time.

[0055] The working principle and advantages of the present invention are: the present invention uses multiple excavation-type slope-forming mechanisms 300 to synchronously turn the soil, and then cooperates with the spraying of soil remediation agents, so that the turned soil is fully mixed with the soil remediation agent, thereby achieving the purpose of fully repairing the soil, and the excavation-type slope-forming mechanism 300 performs deeper turning, which can effectively treat the deeper soil. And the ground after turning forms a trapezoidal slope between two adjacent excavation-type slope-forming mechanisms 300. Since the better growth environment adapted to Coptis chinensis is generally a slope, the trapezoidal slope creates favorable conditions for the growth of Coptis chinensis. After that, Coptis chinensis seeds or seedlings are planted on the slopes on both sides of the trapezoidal slope, and corresponding field management is performed during the growth period of Coptis chinensis. When Coptis chinensis is harvested, the trapezoidal slope is deeply turned by the excavation-type slope-forming mechanism 300, and the soil is improved by coordinating with the soil remediation agent, and a new trapezoidal slope is formed at the gully between the original two trapezoidal slopes, so as to facilitate the planting of Coptis chinensis next time, thereby solving the problem of obstacles to continuous cropping of Coptis chinensis. In summary, the present invention can effectively improve the planting soil of Coptis chinensis, supplement the nutrients missing in the planting soil, fundamentally solve the problem of continuous planting obstacles of Coptis chinensis, and achieve the purpose of treating both the symptoms and the root causes.

[0056] As a preferred embodiment of the present invention, in order to enable the soil remediation agent to fully remediate the soil, the measures taken are to pass the soil remediation agent through each excavation-type slope-forming mechanism 300, and spray it out in atomization along with the rotation of the excavation-type slope-forming mechanism 300. In this way, the turned soil moves to both sides of the excavation-type slope-forming mechanism 300 in an outward-turned and divergent form. In this process, the sprayed soil remediation agent combines with the turned soil in an atomized form, thereby improving the soil remediation effect.

[0057] As a preferred embodiment of the present invention, Figure 2 , 3As shown, all the excavation-type slope-forming mechanisms 300 are mounted on the installation shaft 200, and the axis of each excavation-type slope-forming mechanism 300 coincides with the axis of the installation shaft 200, and the two ends of the installation shaft 200 are respectively rotatably connected to the frame 100, and a transmission wheel 500 coinciding with its axis is mounted on the installation shaft 200. In this embodiment, a liquid guide pipe system 600 is rotatably connected to one end of the installation shaft 200, and an air guide pipe system 700 is connected to the other end of the installation shaft 200. In this embodiment, an axial drive mechanism 400 is constructed between two adjacent excavation-type slope-forming mechanisms 300, and the axial drive mechanism 400 is sleeved outside the installation shaft 200, wherein the liquid guide pipe system 600 is connected to each excavation-type slope-forming mechanism 300, and the air guide pipe system 700 is connected to each axial drive mechanism 400. The working principle and advantages of this embodiment are as follows: in the process of driving the installation shaft 200 to rotate, all the excavation-type slope-forming mechanisms 300 and the axial drive mechanisms 400 connected to the installation shaft 200 rotate along the axis of the installation shaft 200; in the process of turning the soil, the soil remediation agent is pressurized and supplied to the liquid guide pipe system 600, so that the soil remediation agent is evenly distributed to each excavation-type slope-forming mechanism 300, and then atomized and sprayed out by the excavation-type slope-forming mechanism 300, and combined with the turned soil to form a trapezoidal slope. In this embodiment, when it is necessary to change the side slope of the trapezoidal slope, the high-pressure gas is passed into each axial drive mechanism 400 through the gas guide pipe system 700, and then the opening and closing degree of the excavation-type slope-forming mechanism 300 is adjusted to achieve the purpose of adjusting the side slope of the trapezoidal slope.

[0058] As a preferred embodiment of the present invention, Figure 7-15As shown, the excavation type slope forming mechanism 300 includes an assembly seat 205, two slope forming components and a plurality of excavation teeth 301, and the mounting shaft 200 includes a shaft body 201. The assembly seat 205 is constructed on the shaft body 201, and the assembly seat 205 extends outward in the radial direction of the shaft body 201. A plurality of assembly grooves 211 are evenly opened on the outer peripheral wall of the assembly seat 205 along its circumference, and a plurality of connection holes 212 are evenly opened on the assembly seat 205 along its circumference, and each connection hole 212 passes through the two side end faces of the assembly seat 205 along the axis of the assembly seat 205. The plurality of excavation teeth 301 described in this embodiment are evenly arranged along the circumference of the assembly seat 205, and tooth tips 302 and assembly blocks 304 are respectively constructed at both ends of the excavation teeth 301, and the assembly blocks 304 are assembled in the corresponding assembly grooves 211, and each excavation tooth 301 extends outward in the radial direction of the assembly seat 205. In this embodiment, fixing covers 213 are respectively provided on both sides of the assembly seat 205. The two fixing covers 213 are fixed to the assembly seat 205 through a plurality of connecting bolts 214, and each excavation tooth 301 is fixed and restricted on the assembly seat 205. Specifically, each connecting bolt 214 passes through the corresponding connecting hole 212 and the two fixing covers 213, and a connecting nut 215 is threadedly connected to one end of the connecting bolt 214, and the connecting nut 215 is tightened on the end surface of the corresponding fixing cover 213. In this way, according to the damage of the excavation tooth 301, this embodiment can perform operations such as rapid disassembly, maintenance and replacement, etc., to provide convenient conditions for the maintenance of the excavation tooth 301; and different types of excavation teeth 301 can be replaced according to needs, so as to realize excavation operations for different soil matrices and change the excavation depth. The two slope forming components of the present embodiment are respectively arranged on both sides of the assembly seat 205, and each slope forming component is connected to the shaft body 201 and each excavation tooth 301. In this way, the excavation tooth 301 not only plays the role of trench excavation, but also plays the role of connecting the slope forming components. When the shaft body 201 is driven and rotated, the shaft body 201 drives the excavation tooth 301 to rotate, and the slope forming component rotates accordingly, so that the slope forming component excavates the soil on both sides of the excavation tooth 301 and gradually forms a trapezoidal slope. In addition, the soil turned over by the slope forming component is more dispersed, which is conducive to the full combination of the soil and the soil remediation agent. The specific structure of the slope forming component of this embodiment is that the slope forming component includes a connecting sleeve 401 and a plurality of rotary digging blades 308, wherein the connecting sleeve 401 is movably sleeved on the shaft body 201, and the plurality of rotary digging blades 308 are evenly arranged along the circumference of the connecting sleeve 401, one end of each rotary digging blade 308 is hinged to the outer peripheral wall of the connecting sleeve 401, and one end of the rotary digging blade 308 away from the connecting sleeve 401 is hinged to the corresponding excavation tooth 301, and the axial driving mechanism 400 is connected to two connecting sleeves 401 close to each other in two adjacent excavation type slope forming mechanisms 300, so that the slope forming components located on both sides of the assembly seat 205 are both conical structures.In this embodiment, the shaft body 201 is driven to move, so that the slope forming assembly rotates. The slope forming assembly cuts and excavates the soil through the rotary digging blade 308, and tilts the soil outward and throws it. The soil thrown by the rotary digging blade 308 falls on both sides of the groove cut by the rotary digging blade 308, thereby forming two slopes on the sides of the two trapezoidal slopes close to each other. In this embodiment, the axial driving mechanism 400 can be driven by high-pressure gas to perform telescopic movements, so that the two connecting sleeves 401 connected to the axial driving mechanism 400 are close to or away from each other, that is, the connecting sleeve 401 is close to or away from the corresponding assembly seat 205, so that the connecting sleeve 401 drives each rotary digging blade 308 connected thereto to move, thereby changing the taper of the conical structure formed by these rotary digging blades 308, thereby achieving the purpose of changing the slope of the trapezoidal slope.

[0059] As a preferred embodiment of the present invention, Fig.10 , 11 As shown, a strip-shaped adjustment hole 303 is provided on each excavation tooth 301, and the strip-shaped adjustment hole 303 extends along the length direction of the excavation tooth 301. An adjustment rod 309 is movably mounted in the strip-shaped adjustment hole 303. Two locking nuts 310 are threadedly connected to the adjustment rod 309. The two locking nuts 310 are screwed on the end faces of both sides of the excavation tooth 301, and the two ends of the adjustment rod 309 are respectively hinged to the two rotary excavation blades 308 located on both sides of the excavation tooth 301. In this embodiment, the height, slope and width of the trapezoidal slope can be adjusted, which is achieved by controlling the axial drive mechanism 400 on the one hand, and by adjusting the position of the adjustment rod 309 installed in the strip-shaped adjustment hole 303 on the other hand. Specifically, at least one locking nut 310 on each adjusting rod 309 is loosened so that the adjusting rod 309 can move in the bar-shaped adjusting hole 303, and then the position of each adjusting rod 309 in the corresponding bar-shaped adjusting hole 303 is adjusted, and the position of the connecting sleeve 401 connected to the rotary cutting blade 308 is also changed accordingly. After the adjustment is completed, the locking nut 310 is tightened so that the adjusting rod 309 is fixed at the predetermined position of the bar-shaped adjusting hole 303. In this embodiment, the purpose of synchronous adjustment of the slope forming components located on both sides of the assembly seat 205 is achieved by adjusting each adjusting rod 309. In this embodiment, the axial driving mechanism 400 can also be removed, and the taper of the conical slope forming component can be adjusted in a completely manual manner. After the adjustment of the adjusting rod 309 is completed and the locking nut 310 is tightened, the connecting sleeve 401 is fastened to the shaft body 201 to prevent the connecting sleeve 401 and the shaft body 201 from relative movement when not adjusting.

[0060] As a preferred embodiment of the present invention, Figure 3-6As shown, the axial drive mechanism 400 includes a first transmission sleeve 402, a second transmission sleeve 403 and a first connecting spring 405. The first transmission sleeve 402 and the second transmission sleeve 403 are respectively constructed at the ends of the two connecting sleeves 401 that are close to each other, and the ends of the first transmission sleeve 402 and the second transmission sleeve 403 that are close to each other are movably inserted together, a driving cavity 404 is formed in the first transmission sleeve 402 and the second transmission sleeve 403, the first connecting spring 405 is arranged in the driving cavity 404, and the first connecting spring 405 is sleeved outside the installation shaft 200, and the two ends of the first connecting spring 405 are respectively connected to the ends of the two connecting sleeves 401 that are close to each other. An air guide channel 203 is provided on the installation shaft 200, and a plurality of air guide holes 204 are also provided on the installation shaft 200, each of which is connected to the corresponding driving cavity 404, and the other end of the air guide hole 204 is connected to the air guide channel 203, and the air guide channel 203 is connected to the air guide pipe system 700. The air guide pipe system 700 of this embodiment includes an air guide sleeve 702 configured with an air guide joint 701, and the air guide sleeve 702 is rotatably mounted on one end of the installation shaft 200, and an air guide cavity 703 is formed between the air guide sleeve 702 and the end of the installation shaft 200, and the air guide cavity 703 is connected to one end of the air guide channel 203, and the other end of the air guide channel 203 is blocked by a first plug 604, so that high-pressure gas enters the air guide cavity 703 through the air guide joint 701, and is then evenly distributed to each drive cavity 404 through the air guide channel 203, thereby achieving the purpose of driving all axial drive mechanisms 400 to move synchronously; the high-pressure gas in the drive cavity 404 can also be discharged through the air guide channel 203 and the air guide pipe system 700.
