The seeding device 2 comprises a seed box 201, a seed metering assembly 202 and a seeding pipe 203 arranged in sequence. The seed box 201 is a long strip-shaped box body. The lower end of the seed box 201 is conical. When the seed box 201 is installed, support plates 8 are arranged on the both sides of the frame 1. The support plates 8 are bent into "L" shapes. The seed box 201 for storing seeds is arranged between the two support plates 8 and is supported by the support plates 8.

[0043] The seed metering assembly 202 is arranged in communication with the seed box 201. The seed metering assembly 202 is an external fluted roller type seed metering assembly. The seed metering shafts 2021 of the eight seed metering assemblies 202 are connected in series, so that the eight seed metering assemblies 202 can be synchronously driven to realize synchronous seeding.

[0044] The seed metering assembly 202 can uniformly guide the seeds in the seed box 201 into the seeding pipe 203. The driving roller 4 is arranged below the frame 1 and is arranged behind the seeding pipe 203. The driving roller 4 and the seed metering assembly 202 are chain driven. When the driving roller 4 rotates, the seed metering assembly 202 can be driven to realize uniform seed discharge.

[0045] The driving roller 4 comprises a driving shaft 401, rear mounting plates 402 arranged at the both ends of the driving shaft 401 and roller cylinders 403 arranged on the driving shaft 401. The rear mounting plates 402 are adjustably arranged on the frame 1, so that the height of the driving shaft 401 can be changed. The driving shaft 401 is chain driven with the seed metering shaft 2021 of one of the seed metering assemblies 202. Specifically, the seed metering shaft 2021 of one of the seed metering assemblies 202 extends out of the support plate 8 and is chain driven with the driving roller 4. Two sprockets are arranged on the seed metering shaft 2021 and the end of the driving shaft 401 respectively. The two sprockets are connected by a chain 9.

[0046] The roller 403 is in contact with the ground soil and can rotate, the roller 403 rotates together with the driving shaft 401, and the plurality of seed dispenser assemblies 202 are driven to operate synchronously. The roller 403 comprises two discs 4031 and a plurality of round rods 4032 arranged between the two discs 4031, and the roller 403 is a hollow structure, so that the contact area between the roller 403 and the ground is increased, and the stability of the roller 403 is ensured.

[0047] Since the height of the driving roller 4 can be adjusted, in order to ensure the tension of the chain 9, an adjusting assembly 10 for adjusting the tightness of the chain 9 is arranged on one side of the frame 1. The adjusting assembly 10 comprises two vertical plates 101 and an adjusting cross rod 102 arranged between the two vertical plates 101, the adjusting cross rod 102 is an external threaded rod 51, two adjusting nuts 103 are arranged on the adjusting cross rod 102, the vertical plates 101 are clamped by the two adjusting nuts 103, and the fixing of the adjusting cross rod 102 is realized.

By changing the position of the adjusting cross rod 102, the position of the tension sprocket 104 can be adjusted, the tension of the chain 9 is ensured to be appropriate, and the reliability of the chain transmission is ensured.

[0048] Before the seeding device 2 is used for seeding, it is necessary to dig a seed groove with a certain depth and width, so that the seeds can fall into the dug groove. For this purpose, the seeding and ditching roller 3 is rotatably arranged below the front end of the frame 1, and the seeding and ditching roller 3 is arranged in front of the seeding pipe 203, so that the seeding and ditching roller 3 and the driving roller 4 are arranged on both sides of the seeding pipe 203. The seeding and ditching roller 3 is used for ditching, and then the seeding pipe 203 is used for seeding.

[0049] The seeding and ditching roller 3 comprises a ditching shaft 301, a front mounting plate 302 arranged at both ends of the ditching shaft 301, and a plurality of ditching rollers 303 arranged at equal intervals on the ditching shaft 301. The end of the ditching shaft 301 is rotatably connected to the front mounting plate 302 through a bearing seat, and the front mounting plate 302 is adjustably arranged on the frame 1, so as to drive the ditching shaft 301 to rise and fall. Specifically, a plurality of mounting holes 11 arranged vertically are formed in the front mounting plate 302, the plurality of mounting holes 11 are divided into two rows, and any mounting hole 11 is connected and fixed to the frame 1 by bolts. By connecting the bolts with the mounting holes 11 of different heights, the height of the ditching shaft 301 can be adjusted, and the seeding depth can be changed.

[0050] The number of furrowing rollers 303 is eight, and the furrowing rollers 303 and the seeding tubes 203 are in one-to-one correspondence. The circumferential surface of the furrowing roller 303 is a conical surface 12. Through the rotation and rolling of the furrowing roller 303, a row of neat and arranged seed furrows can be formed on the land after rotary tillage, so as to be used for seed sowing. A plurality of furrowing side plates 13 are evenly distributed on the circumferential surface of the furrowing roller 303. The furrowing roller 303 drives the furrowing side plates 13 to rotate, so as to ensure better formation of the furrow.

[0051] The seed furrows are formed by the seeding and furrowing roller 3, and the depth of the seed furrows is controlled. Then, the seeds are discharged into the seed furrows by the seeding device 2. Finally, the land is leveled by the leveling assembly 5. The leveling assembly 5 is adjustably arranged on the frame 1 between the driving roller 4 and the seeding tube 203. Since the adjacent seed furrows are upward ridges, leveling the ridges can promote the soil to cover the seed furrows.

[0052] The leveling assembly 5 comprises threaded rods 51 and leveling plates 52. The leveling plates 52 are comb-shaped, and the leveling plates 52 are parallel to the ground. Threaded rods 51 are vertically arranged at both ends of the leveling plates 52. When the leveling plates 52 are installed, bolts are radially penetrated through the threaded rods 51, and then the bolts are screwed with the leveling plates 52. When the bolts are unscrewed, the leveling plates 52 can be removed. When the threaded rods 51 are installed, the two threaded rods 51 are respectively penetrated through the two sides of the frame 1. Height nuts 14 are respectively arranged on the threaded rods 51 on the upper and lower sides of the frame 1. The two height nuts 14 clamp the frame 1. When the height nuts 14 are tightened, the threaded rods 51 are fixed. When the height nuts 14 are loosened, the threaded rods 51 can be adjusted up and down, so as to control the height adjustment of the leveling plates 52.

[0053] In the embodiment, the pesticide spraying device comprises a liquid storage barrel, a water pump and a pesticide spraying pipe 61 arranged at the rear end of the frame 1. The liquid storage barrel and the water pump are installed at the front end of the tractor. The liquid storage barrel contains configured liquid pesticide or fertilizer. The water pump is powered by the battery of the tractor. The water pump and the liquid storage barrel are not shown in the figure. The pesticide spraying pipe 61 is arranged behind the driving roller 4. The outlet of the pesticide spraying pipe 61 is downwardly directed to the ground. Specifically, the pesticide spraying pipe 61 comprises a pipe and a plurality of nozzles which are evenly arranged on the pipe. The pipe is fixedly connected to the two sides of the frame 1 by pipe clamps. The nozzles are communicated with the pipe and directed to the ground. The liquid storage barrel is communicated with the pesticide spraying pipe 61 through the water pump. The inlet of the water pump is directly connected to the liquid storage barrel, and the outlet of the water pump is communicated with the pesticide spraying pipe 61 through a hose, so as to supply the liquid pesticide or fertilizer to the pesticide spraying pipe 61, thereby realizing the pesticide spraying after seeding.

[0054] A drip irrigation tape laying device 7 is also installed above the middle of the frame 1 to lay the drip irrigation tape immediately after sowing, facilitating subsequent irrigation operations. The drip irrigation tape laying device 7 includes a bracket 71, a support rod 72 for supporting the drip irrigation tape, and a guide pipe 73 for guiding the drip irrigation tape. There are multiple brackets 71, specifically four in this case. The number of brackets 71 depends on the number of sowing pipes 203, with one bracket 71 corresponding to every two sowing pipes 203. The four brackets 71 are arranged in pairs, staggered front and back, on the frame 1, and the cross-section of the brackets 71 is "Y" shaped.

[0055] A support rod 72 is rotatably mounted above the bracket 71. Specifically, the bracket 71 has grooves 15 at both ends, which are recessed downwards. The support rod 72 has smaller diameters at both ends, and bearings are installed at the ends of the support rod 72. These bearings are positioned within the grooves 15 for rotation, ensuring smooth rotation of the support rod 72 and preventing it from detaching from the bracket 71. The support rod 72 is used for installing drip irrigation tape. The drip irrigation tape is an outsourced product, and it is selected to be shipped with H-beam reels, meaning the tape is wound around the H-beam reels.

[0056] Since the purchased drip irrigation tape may have different specifications, the support rod 72 is a rod with external threads. The support rod 72 is also threaded with clamping discs 16. There are two clamping discs 16, which are symmetrically distributed. The clamping discs 16 can directly pass through the bearing and be threaded to the support rod 72. The two clamping discs 16 work together to clamp the drip irrigation tape wrapped on the I-beam reel, so that the drip irrigation tape is fixed on the support rod 72. When the support rod 72 rotates, the drip irrigation tape rotates with it and is released. By adjusting the spacing of the clamping discs 16, I-beam reels of different widths can be installed.

[0057] After release, the drip irrigation tape should be laid in the appropriate location on the land. A guide pipe 73 can be used to guide the drip irrigation tape. During installation, the guide pipe 73 is hinged to the frame 1 and extends downwards at an angle to below the frame 1. Specifically, a fixing frame 17 is installed on the frame 1, positioned behind the support 71. The fixing frame 17 has a "U" shaped cross-section. The number of guide pipes 73 matches the number of supports 71. Eight seeding tubes 203 are grouped in pairs, with one guide pipe 73 corresponding to each group of seeding tubes 203. The upper end of the guide pipe 73 is hinged to the top of the fixing frame 17. A tension spring 18 is installed between the middle of the guide pipe 73 and the bottom of the fixing frame 17 to prevent the guide pipe 73 from swinging upwards. The guide pipe 73 rests against the spraying pipe 61 to limit its swing. The lower end of the guide pipe 73 is close to the ground, guiding the drip irrigation tape to the ground.

[0058] To prevent the drip irrigation tape from being blown away by the wind after installation, it can be laid on shallow ground. Therefore, a trenching plate 19 is installed at the lower end of the guide pipe 73. The trenching plate 19 is an angle steel structure that extends downwards from the lower end of the guide pipe 73. In this way, a trench can be drawn on the ground using the trenching plate 19, and the drip irrigation tape can be laid in the trench. At the same time, two soil-gathering plates 20 arranged in a figure-eight shape are set on both sides of the lower end of the guide pipe 73. These plates guide the soil on both sides of the trench into the trench, thereby burying the drip irrigation tape in the trench and thus burying it on the shallow ground surface, achieving shallow burial of the drip irrigation tape.

[0059] The principle of this utility model is as follows: Before operation, the seeding, drip irrigation, spraying, and mulching machine for sowing and drip irrigation is as follows: medicinal herb seeds are placed into the seed box 201, and the sowing furrowing roller 3, leveling component 5, and drive roller 4 are adjusted to a suitable height to achieve the appropriate sowing depth. At the same time, the I-beam with drip irrigation tape wound around it is threaded onto the support rod 72, and the I-beam is fixed by two clamping discs 16. Then, the support rod 72 is installed on the bracket 71, ensuring that the support rod 72 rotates normally. Drip irrigation tape is installed on all four brackets 71 in the above manner, and then the ends of the four rolls of drip irrigation tape are led out, passed through the guide pipe 73, and extended to the ground. The ends of the drip irrigation tape are pressed and fixed to the edge of the field by a weight, such as soil clods.

[0060] When the sowing, drip irrigation, spraying, and mulching machine is in operation: the tractor drives the rotary tiller and the machine together. When the rotary tiller descends to the ground, the sowing furrow roller 3, the leveling plate 52, and the drive roller 4 come into contact with the ground. As the tractor moves, it provides power to operate the rotary tiller, loosening and tilling the soil. Simultaneously, the sowing furrow roller 3 rotates and compacts the soil, forming furrows. The drive roller 4 rotates, driving the seed metering assembly 202 to guide the seeds into the sowing pipe 203, where they fall into the furrows. The leveling plate 52 then levels the soil, filling the furrows and ensuring the seeds are covered. The water pump starts, pumping liquid pesticides or fertilizers into the spraying pipe 61 and spraying them onto the ground. Because one end of the drip irrigation tape is fixed, it is released as the tractor moves, and guided by the guide pipe 73, it is laid on the ground, thus realizing the sowing, spraying, and drip irrigation tape laying operations for medicinal herbs.

[0061] Example 2:

[0062] This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The differences are as follows: Figures 8-10 As shown, a film covering device 21 is also provided at the rear end of the frame 1. For Chinese medicinal herb seeds that need to be covered with film, the film covering device 21 can be installed separately at the rear end of the frame 1 to lay the film.

[0063] The film covering device 21 comprises a film covering frame 211, a placing rod 212 for bearing the roll-shaped mulch film, a side furrowing wheel 213, a side film pressing wheel 214 and a side soil covering disc 215. The film covering frame 211 is fixed at one end and the rear end of the machine frame 1 by bolt connection, and the side furrowing wheel 213, the placing rod 212, the side film pressing wheel 214 and the side soil covering disc 215 are arranged in sequence from front to back below the film covering frame 211.

[0064] The side furrowing wheel 213 is symmetrical arranged on both sides of the film covering frame 211, and the distance between the two side furrowing wheels 213 is greater than the width of the machine frame 1. The side furrowing wheel 213 is adjustably arranged on the film covering frame 211 in the up-down direction during installation, and the up-down adjustment means of the side furrowing wheel 213 is the same as that of the driving roller 4, that is, a side rod 22 is arranged on the film covering frame 211, a plurality of side holes 23 are arranged on the side rod 22 in the up-down direction, and the height of the side rod 22 can be adjusted by connecting the side hole 23 and the film covering frame 211 by a bolt.

The side soil covering disc 215 is arranged on both sides of the film covering frame 211, and the distance between the two side soil covering discs 215 is slightly greater than that between the two side furrowing wheels 213, so as to guide the soil to the central position.

[0067] The principle of the mulching device 21 is that after a film roll is arranged on the rod 212, one end of the film roll is led out to pass around the edge film pressing wheel 214 and the edge soil covering disc 215 and is fixed at the ground. When the mulching device 21 moves with the frame 1, the edge ditching wheel 213 first forms a ditch on the ground, then the film roll is pulled and released, the film edge corresponds to the position of the previously formed ditch, and then the film edge is pressed into the ditch by the edge film pressing wheel 214, and then the soil is introduced into the ditch by the edge soil covering disc 215, so as to press the film edge, prevent the film from being blown up by the wind, and complete the laying of the film. After the film is laid, the drip irrigation belt is arranged under the film, which plays a fixing role on the drip irrigation belt.
