Description

Technical Field

[0001] The present invention relates to a garden planting device and method, belonging to the technical field of garden planting. Background Art

[0002] Garden maintenance operations are essential after garden planting. Therefore, planting and maintenance are inseparable. In conventional garden landscapes, lawns usually play the role of filling large areas of the ground. Therefore, during the life cycle of garden planting and maintenance, lawns need to be regularly planted and maintained.

[0003] When conventionally planting and maintaining lawns, when the lawn needs to be replaced and maintained, seeds often need to be sown. The conventional sowing method is to directly sow on the surface of the soil layer. This is not conducive to the survival of the seeds and reduces the seed survival rate. Therefore, there are certain problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a garden planting device and method, which solves the problem that when the lawn needs to be replaced and maintained in the prior art, seeds often need to be sown, and the conventional sowing method is to directly sow on the surface of the soil layer, which is not conducive to the survival of the seeds and reduces the seed survival rate.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solutions: The garden planting device includes a main support frame, a rear wheel support frame, a rotating wheel, and fixing blocks. The main support frame is fixedly connected to the rear wheel support frame. The rotating wheel is rotatably arranged on the rear wheel support frame. There are several fixing blocks, and several fixing blocks are fixedly arranged in an equiangular circular array on the outer curved surface of the rotating wheel. The fixing blocks extend obliquely. A planting component for sowing seeds is arranged on the rear wheel support frame.

[0006] By adopting the above technical solutions, during the use of the planting device, the user pushes the main support frame to drive the rear wheel support frame to move, causing the rotating wheel to rotate. The rotation direction of the rotating wheel is opposite to the extension direction of the fixing blocks. The fixing blocks scrape out grooves in the soil layer on the ground. At this time, new seeds are scattered into the grooves. The seeds can easily absorb the moisture under the soil layer. Compared with directly sowing on the surface, the survival rate of the seeds is higher, and the loss rate of the seeds is reduced.

[0007] The present invention is further configured as follows: The planting component includes a water injection cavity opened along the rotation axis of the rotating wheel. A rotating shaft rotatably connected to the rotating wheel is coaxially and fixedly provided on the rear wheel support frame. An outer sleeve coaxially arranged is fixedly sleeved at the end of the rotating shaft. An annular cavity is axially opened inside the outer sleeve. A plurality of drain holes communicating the water injection cavity with the annular cavity are opened on the outer side surface of the outer sleeve. Both ends of the outer sleeve extend outside the rear wheel support frame. The rotating wheel is rotatably connected to the outer sleeve. A water storage tank is fixedly provided on the side of the rear wheel support frame away from the rotating wheel. A water guide pipe is communicated with the water storage tank. One end of the water guide pipe away from the water storage tank is fixedly connected to the end of the outer sleeve. The end of the water guide pipe fixedly connected to the outer sleeve extends into the outer sleeve and is communicated with the annular cavity. An inner liquid discharge cavity is radially opened on the part of the rotating wheel where the fixing block is arranged. An outer liquid discharge cavity is opened inside the fixing block. The outer liquid discharge cavity is communicated with the inner liquid discharge cavity. The inner liquid discharge cavity is communicated with the water injection cavity.

[0008] By adopting the above technical solution, the water storage tank stores a mixed liquid of water and seeds. The valve can be opened and closed manually or automatically. When the valve is opened, the mixed liquid in the water storage tank flows into the annular cavity through the water guide pipe, and then flows into the water injection cavity through the drain holes. The liquid entering the water injection cavity flows towards the inner liquid discharge cavity facing the ground under the action of gravity. During the rotation of the rotating wheel, the fixing block scrapes out a groove in the soil layer. At this time, the mixed liquid flows out through the inner liquid discharge cavity and the outer liquid discharge cavity, and the flowing out mixed liquid enters the groove. At this time, due to the immersion of water, the soil layer in the groove is soaked by water, and the soil layer near the groove is not likely to collapse. At the same time, the mixing of water and seeds can avoid the situation of seed water shortage, and seeds can be sown on the dry soil surface, improving the applicable range of the planting device.

[0009] The present invention is further configured as follows: A sliding cavity is opened on the opposite end wall at the connection of the inner liquid discharge cavity and the outer liquid discharge cavity. A sealing plate is slidably arranged in one of the sliding cavities away from the inclined direction of the outer liquid discharge cavity. The end of the sealing plate passes through the inner liquid discharge cavity and extends into the other sliding cavity to seal and separate the inner liquid discharge cavity and the outer liquid discharge cavity. A plurality of liquid discharge channels are penetrated on the part of the sealing plate located away from the inclined direction of the outer liquid discharge cavity. One end of the sealing plate away from the inclined direction of the outer liquid discharge cavity extends outside the fixing block and the rotating wheel and is fixedly provided with an elastic block. One end of the elastic block facing the rotating wheel is fixedly connected to the rotating wheel. One end of the elastic block away from the rotating wheel is provided with a pointed protrusion.

[0010] By adopting the above technical solution, during the rotation of the rotating wheel, the elastic block first comes into contact with the ground soil layer. After the elastic block contacts the soil layer, it undergoes elastic deformation towards the fixed block and bends. At this time, the elastic block pushes the closing plate to move, and the part of the closing plate where the liquid discharge channel is opened moves to the connection between the inner liquid discharge cavity and the outer liquid discharge cavity. At this time, the mixed liquid in the inner liquid discharge cavity flows through the liquid discharge channel into the inner part of the outer liquid discharge cavity and is discharged. In this way, it can be ensured that when the fixed block and the elastic block do not come into contact with the ground soil layer, the inner liquid discharge cavity is in an unsealed state, and at this time, the mixed liquid cannot flow out, avoiding the waste caused by the premature outflow of the mixed liquid, which is beneficial to reducing the loss rate of seeds.

[0011] The present invention is further configured as follows: Spring cavities extending radially along the rotating wheel are symmetrically opened on both sides of the inner wall of the water injection cavity at the opening part of the inner liquid discharge cavity. A connecting plate is slidably arranged in the spring cavity. One side of the connecting plate away from the axis of the rotating wheel is fixedly provided with a tension spring. The end of the tension spring away from the connecting plate is fixed to the inner wall of the spring cavity. The end of the connecting plate away from the tension spring extends into the water injection cavity. A sealing plate is fixedly arranged at one end of the two connecting plates in the water injection cavity. The sealing plate abuts against the inner wall of the water injection cavity to close the opening of the inner liquid discharge cavity.

[0012] By adopting the above technical solution, under the action of the friction between the connecting plate and the inner wall of the spring cavity, the elastic force of the tension spring cannot pull the connecting plate to slide. As the sealing plate follows the movement of the rotating wheel, the sealing plate gradually sinks into the mixed liquid in the water injection cavity. At this time, the mixed liquid flows into the inner liquid discharge cavity through the opening of the inner liquid discharge cavity. Then, when the sealing plate continues to follow the rotating wheel and moves towards the side closest to the ground soil layer, at this time, under the action of the gravity of the sealing plate and the elastic force of the tension spring, it tightly abuts against the inner wall of the water injection cavity. At this time, the sealing plate closes the opening of the inner liquid discharge cavity, and the mixed liquid in the water injection cavity cannot enter the inner liquid discharge cavity. As the rotating wheel continues to move, after the outer liquid discharge cavity and the inner liquid discharge cavity are connected, the mixed liquid in the inner liquid discharge cavity flows out through the outer liquid discharge cavity. When the mixed liquid has flowed out completely, no new mixed liquid will flow out, thereby restricting the amount of mixed liquid flowing out through the outer liquid discharge cavity each time, and further avoiding the inflow of a large amount of mixed liquid into the soil groove and the waste of the mixed liquid.

[0013] The present invention is further configured as follows: a pressure chamber is provided inside the sealing plate. An insertion block is fixed on the side of the sealing plate facing the opening of the inner liquid discharge chamber. The inside of the insertion block is hollow and is provided with an opening facing the inner liquid discharge chamber. The inside of the insertion block communicates with the pressure chamber. At the opening of the inside of the insertion block facing the inner liquid discharge chamber, two elastic sealing sheets are relatively fixedly arranged. The opposite ends of the elastic sealing sheets abut against each other to close the opening inside the insertion block. An air pressure chamber is provided inside the rotating wheel at one end of a sliding chamber located in the extending direction of the fixed block. A flexible expansion baffle is fixedly arranged inside the air pressure chamber. The inside of the flexible expansion baffle is hollow and communicates with the sliding chamber. The flexible expansion baffle completely separates the communication opening between the sliding chamber and the air pressure chamber. A hose is communicated inside the air pressure chamber. The other end of the hose extends into the water injection chamber and is fixedly connected to the sealing plate. The fixed end of the hose and the sealing plate communicates with the pressure chamber.

[0014] The present invention is further configured as follows: a fixed pressing block is fixedly arranged at the opening of the inner liquid discharge chamber away from the outer liquid discharge chamber. The direction of the fixed pressing block facing the water injection chamber is a converging convex shape. The converging convex end of the fixed pressing block can extend into the inside of the insertion block to separate the two mutually abutting elastic sealing sheets.

[0015] By adopting the above technical solution, after the elastic block contacts the soil layer and deforms, the closing plate is pushed towards the air pressure chamber. At this time, since the sliding chamber and the flexible expansion baffle communicate, the space of the sliding chamber and the flexible expansion baffle becomes smaller, and the air pressure increases, so that the flexible expansion baffle expands. Then the space inside the air pressure chamber becomes smaller and the air pressure increases. At this time, the gas in the air pressure chamber enters the pressure chamber through the hose, so that the pressure chamber is in a high-pressure environment. When the sealing plate abuts against the inner wall of the water injection chamber, at this time, the elastic block bends and abuts against the fixed block and cannot continue to bend, and the converging convex end of the fixed pressing block enters the insertion block to separate the two elastic sealing sheets. At this time, the high-pressure gas in the pressure chamber exerts pressure on the mixed liquid in the inner liquid discharge chamber, so that the mixed liquid quickly sprays out from the outer liquid discharge chamber. In this way, the discharge of the mixed liquid can be completed in a short time. And when the outer liquid discharge chamber opening is blocked by silt, by applying pressure, the mixed liquid can push the silt out of the opening of the outer liquid discharge chamber to complete the normal discharge of the mixed liquid, and avoid the blockage of the outer liquid discharge chamber opening affecting the seeding operation.

[0016] The present invention is further configured as follows: the planting device further includes a front wheel support frame and a compaction wheel. The front wheel support frame is arranged on one side of the rear wheel support frame and is fixedly connected to the main support frame. The compaction wheel is rotatably arranged on the front wheel support frame. The rotation axis of the compaction wheel and the rotation axis of the rotating wheel are in the same horizontal plane. The diameters of the compaction wheel and the rotating wheel are the same.

[0017] By adopting the above technical solution, during the process of the user driving the main support frame to move, the compaction wheel first presses and compacts the soil layer, and then the fixed block on the rotating wheel scrapes out a groove in the soil layer and sprinkles a mixed liquid into it. This can make the formed groove more stable and compact, avoid the collapse of the groove during the movement of the rotating wheel, improve the success rate of sowing seeds into the groove, and is beneficial to improving the survival rate of seeds.

[0018] The present invention is further configured as follows: on both sides of the sealing plate along the axial direction of the rotating wheel, there are movable cavities facing the inner wall of the water injection cavity. An auxiliary sealing plate is slidably arranged in the movable cavity. The sliding direction of the auxiliary sealing plate is the same as that of the connecting plate. One end of the auxiliary sealing plate facing the inner wall of the water injection cavity can extend into the water injection cavity and be hermetically attached to the connecting plate. The two auxiliary sealing plates extending into the water injection cavity and the two connecting plates and the inner wall of the water injection cavity enclose a sealed space.

[0019] The planting method of the garden planting device includes: S1: The user pushes the main support frame to drive the rear wheel support frame to move, so that the rotating wheel rotates. The rotating direction of the rotating wheel is opposite to the extending direction of the fixed block, and the fixed block scrapes out a groove in the ground soil layer; S2: The planting assembly sows seeds into the groove in the soil layer; S3: After the seeds are sown, the groove is backfilled.

[0020] The beneficial effects of the present invention are: During the use of the planting device, the user pushes the main support frame to drive the rear wheel support frame to move, so that the rotating wheel rotates. The rotating direction of the rotating wheel is opposite to the extending direction of the fixed block, and the fixed block scrapes out a groove in the ground soil layer. At this time, new seeds are sown into the groove. The seeds are easy to absorb the water under the soil layer. Compared with directly sowing on the surface, the survival rate of the seeds is higher, and the loss degree of the seeds is reduced. Description of the Drawings

Detailed implementation manner

[0023] In order to facilitate the understanding of the technical means, creative features, achieved purposes and effects of the present invention, the present invention will be further described below with reference to specific drawings.

[0024] As Figures 1 to 2 shown, the garden planting device includes a main support frame 10, a rear wheel support frame 12, a rotating wheel 14 and fixing blocks 30. The main support frame 10 is fixedly connected to the rear wheel support frame 12. The rotating wheel 14 is rotatably arranged on the rear wheel support frame 12. A plurality of fixing blocks 30 are provided. The plurality of fixing blocks 30 are fixedly arranged on the outer curved surface of the rotating wheel 14 in an equiangular circumferential array. The fixing blocks 30 extend obliquely. A planting assembly for sowing seeds is arranged on the rear wheel support frame 12.

[0025] As Figures 2 to 3As shown in the figure, the planting component includes a water injection chamber 15 located along the inner edge of the rotating wheel 14. The water injection chamber 15 is opened along the axial direction of the rotation of the rotating wheel 14. A rotating shaft 20 rotatably connected to the rotating wheel 14 is fixedly arranged on the rear wheel support frame 12. The rotating shaft 20 is coaxially arranged with the rotating wheel 14 and penetrates through the rotating wheel 14. A coaxial outer sleeve 21 is fixedly sleeved outside the rotating shaft 20. An annular chamber 25 is axially opened inside the outer sleeve 21. A plurality of drain holes 26 are opened on the outer side surface of the outer sleeve 21. The drain holes 26 communicate the water injection chamber 15 with the annular chamber 25. Both ends of the outer sleeve 21 penetrate through the rotating wheel 14 and the rear wheel support frame 12 and extend to the outside of the rear wheel support frame 12. The rotating wheel 14 is rotatably connected to the outer sleeve 21. A water storage tank 22 is fixedly arranged on the side of the rear wheel support frame 12 away from the rotating wheel 14. The inside of the water storage tank 22 is hollow and is provided with an opening facing away from the ground soil layer. A box cover 24 is detachably and fixedly installed at the opening. A water guide pipe 23 is communicated with the water storage tank 22. A valve is fixed at the communicating end of the water guide pipe 23 and the water storage tank 22. The end of the water guide pipe 23 away from the water storage tank 22 is fixedly connected to the part of the outer sleeve 21 extending to the outside of the rear wheel support frame 12. The end of the water guide pipe 23 fixed to the outer sleeve 21 extends into the outer sleeve 21 and communicates with the annular chamber 25. A part of the rotating wheel 14 where the fixing block 30 is fixed is radially provided with an inner liquid discharge chamber 47 along the rotating wheel 14. An outer liquid discharge chamber 33 is opened inside the fixing block 30 along the extending direction of the fixing block 30. The outer liquid discharge chamber 33 is communicated with the inner liquid discharge chamber 47. The inner liquid discharge chamber 47 is communicated with the water injection chamber 15.

[0026] As Figures 3 to 4 shown, a sliding chamber 34 is opened on the opposite end wall at the connection between the inner liquid discharge chamber 47 and the outer liquid discharge chamber 33. A closing plate 32 is slidably arranged in one sliding chamber 34 in the direction away from the inclined direction of the outer liquid discharge chamber 33. The end of the closing plate 32 passes through the inner liquid discharge chamber 47 and extends into the other sliding chamber 34 to seal and separate the inner liquid discharge chamber 47 and the outer liquid discharge chamber 33. A plurality of liquid discharge channels 35 are penetrated and opened in the part of the closing plate 32 located in the direction away from the inclined direction of the outer liquid discharge chamber 33. One end of the closing plate 32 away from the inclined direction of the outer liquid discharge chamber 33 extends to the outside of the fixing block 30 and the rotating wheel 14 and is fixedly provided with an elastic block 31. One end of the elastic block 31 facing the rotating wheel 14 is fixedly connected to the rotating wheel 14. One end of the elastic block 31 away from the rotating wheel 14 is provided with a pointed protrusion.

[0027] As Figures 3 to 5As shown, on both sides of the inner wall of the water injection chamber 15 at the opening part of the inner liquid discharge chamber 47, spring chambers 39 extending radially along the rotating wheel 14 are symmetrically arranged. A connecting plate 44 is slidably arranged in the spring chamber 39. On one side of the connecting plate 44 away from the axis of the rotating wheel 14, a tension spring 46 is fixedly arranged. One end of the tension spring 46 away from the connecting plate 44 is fixed to the inner wall of the spring chamber 39. One end of the connecting plate 44 away from the tension spring 46 extends into the water injection chamber 15. At one end of the two connecting plates 44 in the water injection chamber 15, a sealing plate 40 is fixedly arranged. The sealing plate 40 abuts against the inner wall of the water injection chamber 15 to close the opening of the inner liquid discharge chamber 47. There is friction between the connecting plate 44 and the inner wall of the spring chamber 39. The friction between the connecting plate 44 and the inner wall of the spring chamber 39 is greater than the elastic force of the tension spring 46 and less than the sum of the gravity of the sealing plate 40 and the elastic force of the tension spring 46. A pressure chamber 41 is arranged in the sealing plate 40. On the side of the sealing plate 40 facing the opening of the inner liquid discharge chamber 47, an insertion block 42 is fixed. The inside of the insertion block 42 is hollow and provided with an opening facing the inner liquid discharge chamber 47. The inside of the insertion block 42 is communicated with the pressure chamber 41. At the opening of the inside of the insertion block 42 facing the inner liquid discharge chamber 47, two elastic sealing sheets 43 are relatively fixedly arranged. The opposite ends of the elastic sealing sheets 43 abut against each other to close the opening inside the insertion block 42. At one end of a sliding chamber 34 in the extending direction of the fixed block 30, an air pressure chamber 36 located in the rotating wheel 14 is arranged. A flexible expansion baffle 37 is fixedly arranged in the air pressure chamber 36. The inside of the flexible expansion baffle 37 is hollow and communicated with the sliding chamber 34. The flexible expansion baffle 37 completely separates the communicating opening between the sliding chamber 34 and the air pressure chamber 36. A hose 38 is communicated in the air pressure chamber 36. The other end of the hose 38 extends into the water injection chamber 15 and is fixedly connected to the sealing plate 40. The fixed end of the hose 38 and the sealing plate 40 is communicated with the pressure chamber 41. At the opening of the inner liquid discharge chamber 47 away from the outer liquid discharge chamber 33, a fixed pressing block 45 is fixedly arranged. The direction of the fixed pressing block 45 facing the water injection chamber 15 is a converging convex shape. The converging convex end of the fixed pressing block 45 can extend into the inside of the insertion block 42 to separate the two mutually abutting elastic sealing sheets 43.

[0028] As Figures 5 to 6 shown, on both sides of the sealing plate 40 along the axial direction of the rotating wheel 14, moving chambers 49 facing the inner wall of the water injection chamber 15 are arranged. An auxiliary sealing plate 48 is slidably arranged in the moving chamber 49. The sliding direction of the auxiliary sealing plate 48 is the same as the sliding direction of the connecting plate 44. One end of the auxiliary sealing plate 48 facing the inner wall of the water injection chamber 15 can extend into the water injection chamber 15 and is hermetically attached to the connecting plate 44. The two auxiliary sealing plates 48 extending into the water injection chamber 15, the two connecting plates 44 and the inner wall of the water injection chamber 15 surround and form a sealed space.

[0029] As Figures 2 to 3As shown in the figure, the planting device further includes a front wheel support frame 11 and a compaction wheel 13. The front wheel support frame 11 is arranged on one side of the rear wheel support frame 12 and fixedly connected to the main support frame 10. The compaction wheel 13 is rotatably arranged on the front wheel support frame 11. The rotation axis of the compaction wheel 13 and the rotation axis of the rotating wheel 14 are in the same horizontal plane, and the diameters of the compaction wheel 13 and the rotating wheel 14 are the same. During the process of the user driving the main support frame 10 to move, the compaction wheel 13 first presses and compacts the soil layer, and then the fixing block 30 on the rotating wheel 14 scrapes out a groove in the soil layer and spreads the mixed liquid into it. This can make the formed groove more stable and compact, avoid the collapse of the groove during the movement of the rotating wheel 14, improve the success rate of sowing seeds into the groove, and is beneficial to improving the survival rate of seeds.

[0030] During the daily use of the planting device, the fixing block 30 can scrape out a groove in the soil layer. At this time, new seeds are sown into the groove, and the seeds are easy to absorb the moisture under the soil layer. Compared with directly sowing on the surface, the survival rate of the seeds is higher in this way, and the loss degree of the seeds is reduced.

[0031] The storage water tank 22 stores a mixed liquid of water and seeds. The valve can be opened and closed manually or automatically. After the valve is opened, the mixed liquid in the storage water tank 22 flows into the annular cavity 25 through the water guide pipe 23, and then flows into the water injection cavity 15 through the drain hole 26. The liquid entering the water injection cavity 15 flows towards the inner liquid discharge cavity 47 facing the ground under the action of gravity. During the rotation of the rotating wheel 14, the fixing block 30 scrapes out a groove in the soil layer. At this time, the mixed liquid flows out through the inner liquid discharge cavity 47 and the outer liquid discharge cavity 33, and the flowing out mixed liquid enters the groove. At this time, due to the immersion of water, the soil layer in the groove part is soaked by water. At this time, the soil layer near the groove is not easy to collapse, and at the same time, the mixing of water and seeds can avoid the situation of seed water shortage, and seeds can also be sown on the dry soil surface, improving the applicable range of the planting device.

[0032] During the rotation of the rotating wheel 14, the elastic block 31 first comes into contact with the ground soil layer. After the elastic block 31 comes into contact with the soil layer, it undergoes an elastic deformation that bends towards the fixing block 30. At this time, the elastic block 31 pushes the closing plate 32 to move, and makes the part of the closing plate 32 where the liquid discharge channel 35 is opened move to the connection between the inner liquid discharge cavity 47 and the outer liquid discharge cavity 33. At this time, the mixed liquid in the inner liquid discharge cavity 47 flows through the liquid discharge channel 35 into the outer liquid discharge cavity 33 and is discharged. This can ensure that when the fixing block 30 and the elastic block 31 are not in contact with the ground soil layer, the inner liquid discharge cavity 47 is not in a closed state, and at this time, the mixed liquid cannot flow out, avoiding the waste caused by the premature outflow of the mixed liquid and being beneficial to reducing the loss rate of seeds.

[0033] Under the action of the frictional force between the connecting plate 44 and the inner wall of the spring chamber 39, the elastic force of the tension spring 46 cannot pull the connecting plate 44 to slide. As the sealing plate 40 follows the movement of the rotating wheel 14, the sealing plate 40 gradually sinks into the mixed liquid located in the water injection chamber 15. At this time, the mixed liquid flows into the inner drain chamber 47 through the opening of the inner drain chamber 47. Then, when the sealing plate 40 continues to follow the rotating wheel 14 and moves towards the side closest to the ground soil layer, at this time, under the action of the gravity of the sealing plate 40 and the elastic force of the tension spring 46, it is in close contact with the inner wall of the water injection chamber 15. At this time, the sealing plate 40 closes the opening of the inner drain chamber 47, and the mixed liquid in the water injection chamber 15 cannot enter the inner drain chamber 47. As the rotating wheel 14 continues to move, after the outer drain chamber 33 and the inner drain chamber 47 are connected, the mixed liquid in the inner drain chamber 47 flows out through the outer drain chamber 33. When the mixed liquid has flowed out completely, no new mixed liquid will flow out, thereby restricting the amount of mixed liquid flowing out through the outer drain chamber 33 each time, and thus avoiding a large amount of mixed liquid flowing into the soil groove and avoiding the waste of the mixed liquid.

[0034] After the elastic block 31 comes into contact with the soil layer and deforms, the closing plate 32 is pushed towards the air pressure chamber 36. At this time, since the sliding chamber 34 and the flexible expansion baffle 37 are connected, the space of the sliding chamber 34 and the flexible expansion baffle 37 becomes smaller and the air pressure rises, thereby causing the flexible expansion baffle 37 to expand. Then, the space in the air pressure chamber 36 becomes smaller and the air pressure rises. At this time, the gas in the air pressure chamber 36 enters the pressure chamber 41 through the hose 38, making the pressure chamber 41 in a high-pressure environment. When the sealing plate 40 abuts against the inner wall of the water injection chamber 15, at this time, the elastic block 31 bends and abuts against the fixed block 30 and cannot continue to bend, and the converging convex end of the fixed pressing block 45 enters the insertion block 42 to separate the two elastic sealing sheets 43. At this time, the high-pressure gas in the pressure chamber 41 exerts pressure on the mixed liquid in the inner drain chamber 47, causing the mixed liquid to quickly spray out from the outer drain chamber 33. In this way, the discharge of the mixed liquid can be completed in a short time. And when there is a situation where the outer drain chamber 33 opening is blocked by silt, by applying pressure, the mixed liquid can push the silt out of the opening of the outer drain chamber 33 to complete the normal discharge of the mixed liquid and avoid the blockage of the outer drain chamber 33 opening affecting the seeding operation.

[0035] During the movement of the rotating wheel 14, the liquid level of the mixed liquid in the water injection chamber 15 does not submerge the outer sleeve 21. During the movement of the sealing plate 40 following the rotating wheel 14, when the sealing plate 40 is not in contact with the inner wall of the water injection chamber 15 and the sealing plate 40 is below the liquid level of the mixed liquid, at this time, the mixed liquid enters the inner liquid discharge chamber 47. At the same time, when the liquid in the inner liquid discharge chamber 47 is full, when the sealing plate 40 moves towards the inner wall of the water injection chamber 15, the insertion block 42 inserts into the inner liquid discharge chamber 47, and the fixed pressing block 45 pushes open the abutting ends of the two elastic sealing sheets 43. As the sealing plate 40 moves towards the water injection chamber 15, the auxiliary sealing plate 48 abuts against the inner wall of the water injection chamber 15, and the auxiliary sealing plate 48, the inner wall of the water injection chamber 15, and the connecting plate 44 form a sealed space. The mixed liquid located in the sealed space will flow into the pressure chamber 41. At this time, the air pressure in the pressure chamber 41 further increases, thereby increasing the initial velocity of the mixed liquid ejected from the outer liquid discharge chamber 33, which is beneficial to improving the cleaning effect on the blocked part. When the sealing plate 40 is above the liquid level of the mixed liquid and the sealing plate 40 is in contact with the inner wall of the water injection chamber 15, the abutting ends of the two elastic sealing sheets 43 are pushed open by the fixed pressing block 45. At this time, the gas can enter the pressure chamber 41 to keep the air pressure in the pressure chamber 41 stable for the next use. When the sealing plate 40 is about to move to the highest point of the rotating wheel 14 from the ground soil layer, the gravity of the sealing plate 40 and the elastic force of the tension spring 46 are greater than the friction force between the connecting plate 44 and the spring chamber 39. At this time, the sealing plate 40 separates from the inner wall of the water injection chamber 15.
