DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 7As shown, a Chinese medicinal material sowing mechanism comprises a support frame 1, wherein the support frame 1 is slidably connected to a plurality of vertical sliding frames 2 in a front-rear manner, each of the sliding frames 2 and the support frame 1 is jointly equipped with a distance adjusting mechanism, and a furrowing disc knife 4 is rotatably connected to the bottom, each of the furrowing disc knives 4 is equipped with an electric rotary drive mechanism, a portion of the circumference of the furrowing disc knife 4 close to the outer circumferential wall is penetrated by a plurality of furrowing grooves 6 at equal angles, and a coaxial disc-shaped accommodating groove 7 is provided in the middle, the accommodating groove 7 penetrates the front part of the furrowing disc knife 4, a plurality of conveying channels 8 are opened at equal angles on the inner circumference of the furrowing disc knife 4, the accommodating groove 7 is connected to each of the furrowing grooves 6 through the conveying channel 8, the furrowing disc knife 4 is rotatably connected to a plurality of axial adjusting bolts 9 at equal angles, a fastening nut 10 is threadedly connected to the rear of each adjusting bolt 9, and a stopper is threadedly connected to the middle. 11, each of the blocks 11 is respectively slidably connected to the connecting transition between the conveying channel 8 and the receiving groove 7 in front and behind, and can completely block the conveying channel 8, the sliding frame 2 is fixed with a shield 12, the shield 12 is rotatably connected to the receiving groove 7 and is in close contact with each of the blocks 11, a feed trough 13 is penetrated at the lower left part of the shield 12, and any block 11 can be aligned with the feed trough 13 during the rotation of the ditching disc knife 4, a feed pipe 14 is fixed to the upper part of the shield 12 that penetrates and extends upward, and the feed pipe 14 is equipped with an intermittent feed mechanism and an intermittent water injection mechanism, a controller 17 of an external power supply is fixed at the bottom end of the support frame 1 (the controller 17 is a known prior art, such as a single-chip microcomputer, a plc and an industrial computer), and a connecting seat 18 is fixed to the right end, and the sowing mechanism is also equipped with a soil covering mechanism 19.

[0022] Before use, the connecting seat 18 is used to connect with the external traction device, and the distance between each sliding frame 2 is adjusted by the distance adjusting mechanism, so that the distance between each furrowing disc cutter 4 can be adjusted, and then the row spacing can be adjusted. When in use, the furrowing disc cutter 4 is controlled by the electric rotary drive mechanism to rotate counterclockwise at an appropriate speed (the speed is determined according to the soil environment. If the soil is relatively loose, a low speed can be used. If the soil is relatively compacted, a high speed can be used. The rotation direction is observed from the main viewing angle). Then, the external traction device is used to lower the sowing mechanism so that the depth of the furrowing disc cutter 4 inserted into the soil is consistent with the sowing depth. During this period, the traction device is used to drag the sowing mechanism to the right, so that the rotating furrowing disc cutter 4 can be used to furrow the soil. During the furrowing process, the external traction device is kept in uniform motion, and the intermittent feeding mechanism is used to intermittently drop seeds into the lower feeding pipe 14, and the intermittent water injection mechanism is used to intermittently inject an appropriate amount of water into the lower feeding pipe 14. When the seeds are mixed with water, the seeds can absorb water first to facilitate their germination. Before use, the corresponding adjusting bolts 9 and fastening nuts 10 are adjusted according to the needs of the plant spacing, so that an appropriate amount of blocks 11 are used to close the conveying channel 8, and an appropriate amount of blocks 11 are used to release the closure of the conveying channel 8. After the adjustment is completed, the fastening nuts 10 are tightened to press against the rear end of the furrowing disc 4 to reduce accidental rotation of the adjusting bolts 9. When the unblocked conveying channel 8 is aligned with the feeding trough 13, the mixture of water and seeds can be discharged from the conveying channel 8 and the furrowing groove 6 under the action of gravity. At this time, the furrowing disc 4 on the right side of the furrowing groove 6 is performing a furrowing operation, so it can support the soil ditch and maintain its stability. Therefore, the discharged seeds can directly fall to the bottom of the ditch, and then be covered with soil by the covering mechanism 19 to complete the planting. Due to the flat structural characteristics of the ditching disc 4, when the depth of its insertion into the soil continues to increase, the shape of the soil ditch it forms is smaller than the traditional inverted ridge shape. Therefore, the increase in the amount of ditching and covering work is also smaller than that of the traditional sowing mechanism. Therefore, the water loss and dust it causes are also less, which is also conducive to improving work efficiency.
