The surface of the soil covering roller 91 is provided with a notch 911 for the soil to escape from the soil covering roller 91.

[0037] It should be noted that the pesticide spraying device 2, the rotary tillage device 3, the ridging device 4, the seed rope sowing device 6, the fertilizing device 5, the drip irrigation tape laying device 7, the film laying device 8 and the soil covering device 9 are arranged in sequence along the frame 1, which means that during the operation of the frame 1, the farming operations of pesticide spraying, rotary tillage, ridging, sowing, fertilizing, laying drip irrigation tape, laying film and covering soil are completed in sequence according to the operating order.

[0038] The frame 1 described in this embodiment is provided with a pesticide spraying device 2, a rotary tiller device 3, a ridging device 4, a seed rope sowing device 6, a fertilizing device 5, a drip irrigation belt laying device 7, a film laying device 8 and a soil covering device 9. During use, the seeding machine sprays the ground with the pesticide spraying device 2 to prevent insect disease damage to the plant and also has a weeding effect. The rotary tiller device 3 is located at the rear side of the spraying rod 24. The rotary tillage blade 31 tills the ground after the spraying of the pesticide, which can effectively break the soil and improve the looseness and air permeability of the soil to facilitate the growth of the root system of the plant and the planting of crops. At the same time, it can also evenly disperse the pesticide in the soil to improve the effect of the pesticide. The ridging device 4 integrates the loose soil into ridges and forms ridge platforms and ridge furrows. The ridging device 4 can make the soil looser, increase the air permeability and drainage of the soil, and help the circulation of air and water in the soil, thereby improving the compaction condition of the soil; the seed rope sowing device 6 guides the seed rope to The seeds are introduced into the ridge to sow the seeds. In this embodiment, seed ropes are used for sowing, which can ensure the spacing between plants, make the arrangement of plants more scientific and reasonable, and reduce the waste of seeds. At the same time, the use of seed ropes can make seed sowing simpler and more convenient; the fertilization device 5 can apply fertilizer to the ridge to supplement nutrition for the growth of seeds; the drip irrigation belt laying device 7 can lay the drip irrigation belt into the ridge, and the drip irrigation belt can improve the irrigation efficiency, reduce the occurrence of plant diseases, and make subsequent irrigation operations more convenient and simple; the film laying device 8 can lay a film on the soil, and the film cooperates with the ridge platform to form a greenhouse effect in the ridge, thereby improving the growth environment of the plants and helping to increase the yield of the plants. After the film laying device 8 lays the film on the soil, the covering plate 92 pushes the surrounding soil into the covering roller 91. As the covering roller 91 rotates, the soil falls from the notch 911 onto the film, which can effectively cover the film and make the laying of the film more firm and reliable.

[0039] In this embodiment, the pesticide spraying device 2, the rotary tillage device 3, the ridging device 4, the seed rope sowing device 6, the fertilizing device 5, the drip irrigation tape laying device 7, the film laying device 8 and the soil covering device 9 are integrated on the frame 1, so that the seeder can complete the farming operations of pesticide spraying, rotary tillage, ridging, sowing, fertilizing, laying drip irrigation tape, laying film and covering soil in sequence. That is, the entire sowing and farming operations can be completed using this embodiment without the need to use other agricultural machinery, which can save farming costs; in addition, the seeder can gradually complete all farming operations during operation without repeated operation, which can greatly improve farming efficiency.

[0040] like Figure 2As shown, the spraying device 2 in this embodiment also includes a driving pump 21, the driving pump 21 has a first inlet and a first outlet, the medicine storage barrel 22 has an addition port 223, a second inlet 222 and a second outlet 221, wherein the first inlet and the second outlet 221 are connected through a hose, and the second outlet 221 is located at the lower side of the medicine storage barrel 22, and the second inlet 222 is located at the upper side of the medicine storage barrel 22, so that more water in the medicine storage barrel 22 flows into the driving pump 21 through the second outlet 221, and the first outlet is connected to a three-way joint 23, wherein the two ends of the three-way joint 23 are respectively connected to the second inlet 222 and the spraying rod 24, and a control valve is provided in the three-way joint 23 so that The first outlet is only connected to the second inlet 222 or the spray rod 24. When the spraying device 2 is first used, the user first adds medicine and water into the medicine storage barrel 22 through the adding port 223, and then starts the driving pump 21. The driving pump 21 draws water from the second outlet 221 through a hose. At this time, the control valve in the three-way joint 23 controls the first outlet to be connected with the second inlet 222, that is, the driving pump 21 and the medicine storage barrel 22 form a circulation loop. Therefore, the driving pump 21 will flow the water back into the medicine storage barrel 22 through the second inlet 222. The water and the medicine can be fully mixed and circulated for multiple times, so that the medicine and water can be fully dissolved and form a medicine solution, which helps to improve the effect of the medicine solution.

[0041] When the water and the medicine are fully mixed, the control valve in the three-way joint 23 controls the first outlet to be connected with the spray rod 24, and then the medicine in the medicine storage barrel 22 flows into the driving pump 21 through the second outlet 221 and the first inlet, and then flows into the spray rod 24 through the first outlet of the driving pump 21. Finally, the medicine is sprayed from the spray rod 24 onto the ground, and the spraying of the medicine is realized, thereby preventing insect and disease damage to plants and achieving a weeding effect. It should be noted that the medicine storage barrel 22 and the driving pump 21 described in this embodiment are both fixed to the upper end of the rotary tiller device 3, and the spray rod 24 is distributed along the length direction of the rotary tiller device 3 and fixed to the front side of the rotary tiller device 3.

[0042] like Figure 2 and Figure 3 As shown, the rotary tiller device 3 in this embodiment also includes a casing, the bottom of the casing is open and a driving shaft is provided in the casing, a rotary tiller blade 31 is fixed on the driving shaft, a soil retaining plate 33 is provided on the rear side of the casing, and a plurality of soil dividing shovels 32 are installed at the lower end of the soil retaining plate 33, and mounting frames 34 extending to the front side of the frame 1 are provided on both sides of the casing, and a plurality of mounting holes are provided on the mounting frames 34, and a depth limiting roller 35 is provided between the two mounting frames 34, and the depth limiting roller 35 is rotatably connected to the mounting frames 34 through a rotating shaft, and a plurality of roller teeth 351 distributed at intervals along the circumferential direction are provided on the surface of the depth limiting roller 35, and the mounting frames 34 are connected to the casing through mounting holes at different positions, so that the distance between the depth limiting roller 35 and the ground can be changed.

[0043] During the operation of the seeder, the depth limiting roller 35 contacts the ground and rotates with the movement of the seeder. The roller teeth 351 can increase the friction between the depth limiting roller 35 and the ground, thereby driving the depth limiting roller 35 to rotate, reducing the possibility of sliding friction between the depth limiting roller 35 and the ground; at the same time, the driving shaft drives the rotary tillage blade 31 to rotate, and the rotary tillage blade 31 can effectively crush the soil. The soil splashes as the rotary tillage blade 31 rotates, and the retaining plate 33 can effectively limit the splash range of the soil and keep the soil in place; in addition, the soil dividing shovel 32 includes two baffles distributed in an eight-shaped shape, and the spacing between the two baffles gradually increases as they move away from the rotary tillage blade 31. When the soil dividing shovel 32 passes through the loose soil, the soil dividing shovel 32 can push the soil to both sides, thereby forming the prototype of a ridge.

[0044] like Figure 4 and Figure 5 As shown, the ridging device 4 in this embodiment includes a ridging driver 44 and a ridging shaft 41. The ridging driver 44 is transmission-connected to the ridging shaft 41 and controls the rotation of the ridging shaft 41. A plurality of ridging disks 42 and sleeves 43 are provided on the ridging shaft 41. The ridging disk 42 is truncated cone-shaped. Two ridging disks 42 are symmetrically connected at both ends of the sleeve 43 to form a ridging mechanism. The end of the ridging disk 42 with a smaller diameter is close to the end of the sleeve 43, and there is a gap between two adjacent ridging mechanisms. During the operation of the seeder, after the rotary tiller device 3 breaks the soil, the ridging device 4 pushes the loose soil, and then the soil forms a ridge platform under the action of the ridging mechanism, and a ridge ditch is formed in the gap between the two adjacent ridging mechanisms, thereby completing the ridging operation.

[0045] like Figure 6 , Figure 7 and Fig.10As shown, the seed rope sowing device 6 in this embodiment includes a seed rope disc 61, a sowing wheel 62 and a sowing tube 63, wherein the seed rope disc 61 is rotatably installed on the upper side of the frame 1, and a seed rope is wound on the seed rope disc 61. The sowing wheel 62 includes a fixed frame 621 and two guide wheels 623, wherein the bottom end of the fixed frame 621 is fixed on the frame 1, and the top of the fixed frame 621 is provided with a cross bar 622, and the two ends of the cross bar 622 extend to the two sides of the fixed frame 621 respectively, and the two guide wheels 623 are respectively rotatably connected to the two ends of the cross bar 622 and distributed on both sides of the cross bar 622. The seed rope sowing device 6 is provided with two sowing tubes 63, and the two sowing tubes 63 The upper end is vertically arranged and is respectively located below the two guide wheels 623. A sowing shovel 64 is provided on the front side of the bottom end of the sowing tube 63, and the bottom end of the sowing tube 63 is bent toward the rear side of the sowing shovel 64. During the operation of the seeder, the seed rope disc 61 rotates to release the seed rope. The seed rope enters the sowing tube 63 under the guidance of the guide wheel 623 and is placed into the furrow along with the sowing tube 63. In addition, when the seeder is running, the sowing shovel 64 extends into the furrow and opens a groove in the furrow. Since the sowing shovel 64 is located in front of the sowing tube 63, the seed rope will enter the groove after following the bottom of the sowing tube 63, thereby completing the sowing of the seed rope.

[0046] In this embodiment, seed ropes are used for sowing, which can ensure the spacing between plants, make the arrangement of plants more scientific and reasonable, reduce seed waste, and also make seed sowing simpler and more convenient. In addition, two guide wheels 623 are provided on the seeding wheel 62, which can guide the two seed ropes into the same ditch at the same time.
