[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-5 This invention provides a combined grassland root cutting, fertilization, and reseeding operation device, including a vehicle body 1, a power box 6 mounted on the vehicle body 1, and further including:

[0031] The root cutting assembly includes several front cutting wheels 5 disposed at the bottom of the front end of the vehicle body 1 and several rear cutting wheel groups disposed at the bottom of the rear end of the vehicle body 1. The front cutting wheels 5 and the rear cutting wheel groups are respectively connected to the power box 6 for transmission.

[0032] The seeding assembly includes a seeder 11 fixedly connected to the vehicle body 1. The bottom of the seeder 11 is connected to a seed guide tube 12. The seeder 11 is used to transport grass seeds into the seed guide tube 12, and the seed guide tube 12 is used to sow grass seeds into the grooves cut by the front cutting wheel 5.

[0033] The fertilization assembly includes a fertilizer applicator 13 fixedly connected to the vehicle body 1. The bottom of the fertilizer applicator 13 is connected to a fertilizer guide tube 14. The fertilizer applicator 13 is used to transport fertilizer into the fertilizer guide tube 14, and the fertilizer guide tube 14 is used to spread fertilizer into the groove cut by the front cutting wheel 5.

[0034] The main function of the front cutting wheel 5 is to cut grass roots in the soil. The main function of the cutting wheel assembly is to further cut grass roots in the soil at the rear of the vehicle body 1, ensuring thorough root cutting. The main function of the seeder 11 is to input grass seeds into the seed guide tube 12 at a certain rate. The main function of the seed guide tube 12 is to accurately sow grass seeds into the grooves cut by the front cutting wheel 5 in the soil. The main function of the fertilizer applicator 13 is to accurately sow fertilizer into the fertilizer guide tube 14 at a certain rate. The main function of the fertilizer guide tube 14 is to accurately spread fertilizer into the grooves cut by the front cutting wheel 5 in the soil and cover the grass seeds. Overall, this invention combines grass root cutting with fertilization and sowing, making it more suitable for severely degraded sheepgrass grasslands. While cutting grass roots, grass seeds and fertilizer can be sown into the grooves cut by the cutting wheel in the soil, resulting in high sowing and fertilization efficiency and contributing to the treatment of severely degraded grasslands. Furthermore, the invention features two sets of cutting wheels, front and rear, allowing for more thorough cutting of grass roots in the soil.

[0035] The scheme was further optimized by setting one front cutting wheel 5 and one rear cutting wheel group accordingly;

[0036] The rear cutting wheel assembly includes two sets of rear cutting wheels 15, and the plane where the front cutting wheel 5 is located is in the middle of the plane where the two rear cutting wheels 15 are located.

[0037] like Figure 2 As shown, one set of front cutting wheels 5 corresponds to two sets of rear cutting wheels 15. During operation, the two sets of rear cutting wheels 15 can not only cut the grass roots on both sides of the cutting position of the front cutting wheel 5, improving the cutting efficiency, but also push the soil on both sides of the trench cut by the front cutting wheel 5 towards the middle, achieving the effect of automatic soil covering after sowing and fertilization.

[0038] Further optimize the plan, such as Figure 1 As shown, the edges of the front cutting wheel 5 and the rear cutting wheel 15 are provided with wavy cut surfaces 51. The wavy cut surfaces 51 can not only improve cutting efficiency and reduce cutting resistance, but also expand the width of the groove after cutting, which is convenient for sowing and fertilization.

[0039] In a further optimized design, the front bottom of the vehicle body 1 is rotatably connected to a front rotating shaft 17 via a connecting rod 4, and several front cutting blade wheels 5 are fixedly mounted on the front rotating shaft 17. The front rotating shaft 17 is connected to the power box 6 via a transmission.

[0040] The rear bottom of the vehicle body 1 is rotatably connected to a rear rotating shaft 29 via a connecting rod 4. Several rear cutting blade wheels 15 are fixedly sleeved on the rear rotating shaft 29, and the rear rotating shaft 29 is connected to the power box 6 for transmission.

[0041] like Figure 1 and Figure 2 As shown, the output end of the power box 6 is connected to a first output shaft 18, on which a third sprocket 19 is fixedly mounted. A first sprocket 7 is fixedly mounted on the front rotating shaft 17. The third sprocket 19 and the first sprocket 7 are connected by a chain drive. A fourth sprocket 20 is also fixedly mounted on the first output shaft 18. A second sprocket 16 is rotatably connected to the rear of the vehicle body 1. The second sprocket 16 and the fourth sprocket 20 are connected by a chain drive. The second sprocket 16 is connected to an eighth sprocket 27 via a connecting shaft. A ninth sprocket 28 is fixedly mounted on the rear rotating shaft 29. The ninth sprocket 28 and the eighth sprocket 27 are connected by a chain drive.

[0042] Further optimization of the scheme: a transfer case 8 is fixedly connected to the vehicle body 1. The transfer case 8 is equipped with a clutch on / off assembly and a transmission 40. The input end of the transmission 40 is connected to the power box 6 through the clutch on / off assembly.

[0043] like Figure 1 and Figure 2 As shown, the main function of the transmission 40 is to enable the seeder 11 and the fertilizer applicator 13 to operate at a suitable speed.

[0044] In a further optimized design, the seeder 11 includes a first rotating shaft 24 rotatably connected in the seeder 11 and several working chambers opened in the seeder 11. The first rotating shaft 24 is connected to the output end of the gearbox 40. Several seeding wheels 32 are fixedly sleeved on the first rotating shaft 24. The seeding wheels 32 are respectively located in several working chambers. Several holding grooves 33 are equally spaced on the side wall of the seeding wheel 32. The inner wall of the working chamber is in contact with the side wall of the seeding wheel 32. The working chamber is connected to the seed guide tube 12.

[0045] The design is further optimized so that the top and bottom of the working chamber are connected to an upper channel 34 and a lower channel 35, respectively. The top of the lower channel 35 is connected to the holding trough 33, and the bottom of the lower channel 35 is connected to the seed guide tube 12 through the seed drop port 30 opened at the bottom of the seeder 11. The top of the upper channel 34 is connected to the seed storage box 9, and the bottom of the upper channel 34 is connected to the holding trough 33.

[0046] like Figure 2 As shown, a sprocket set 23 is fixedly sleeved on one end of the first rotating shaft 24, and the output end of the gearbox is connected to the sixth sprocket 22 through the rotating shaft. The sixth sprocket 22 and the sprocket set 23 are connected by chain drive.

[0047] like Figure 1 and Figure 3As shown, the gearbox 40 drives the first rotating shaft 24 to rotate counterclockwise, causing the sowing wheel 32 to rotate counterclockwise. Grass seeds fall from the seed storage box 9 into the upper channel 34 and automatically fall into several holding troughs 33 exposed at the bottom of the upper channel 34. As the sowing wheel 32 continues to rotate, the holding troughs 33 containing grass seeds are exposed at the top of the lower channel 35. The grass seeds fall into the trench through the lower channel 35, the seed drop port 30 and the seed guide tube 12, completing the sowing work.

[0048] In a further optimized design, the fertilizer applicator 13 includes a second rotating shaft 26 rotatably connected in the fertilizer applicator 13 and several fertilizer application chambers opened in the fertilizer applicator 13. The second rotating shaft 26 is connected to the output end of the gearbox 40. Several fertilizer application wheels 37 are fixedly sleeved on the second rotating shaft 26. The several fertilizer application wheels 37 are respectively located in several fertilizer application chambers. Several baffles 38 are fixedly connected at equal intervals on the side wall of the fertilizer application wheel 37. The baffles 38 fit against the side wall of the fertilizer application chamber. The fertilizer application chamber is connected to the fertilizer guide pipe 14.

[0049] In a further optimized design, the top and bottom of the fertilization chamber are connected to an inlet channel 39 and an outlet channel 36, respectively. The top of the outlet channel 36 is correspondingly set with a baffle 38, and the bottom of the outlet channel 36 is connected to a fertilizer guide pipe 14 through a fertilizer drop outlet 31 opened at the bottom of the fertilizer applicator 13. The top of the inlet channel 39 is connected to a fertilizer storage box 10, and the bottom of the inlet channel 39 is correspondingly set with a baffle 38.

[0050] like Figure 2 As shown, a seventh sprocket 25 is fixedly sleeved on one end of the second rotating shaft 26, and the sprocket group 23 is connected to the seventh sprocket 25 through a chain.

[0051] like Figure 1 and Figure 3 As shown, when the gearbox 40 drives the first rotating shaft 24 to rotate counterclockwise, it drives the second rotating shaft 26 to rotate counterclockwise simultaneously, causing the fertilizer wheel 37 to rotate counterclockwise. Fertilizer falls from the fertilizer storage box 10 into the feed channel 39 and automatically falls between the two baffles 38. As the fertilizer wheel 37 continues to rotate, the fertilizer is pushed by the baffles 38 into the discharge channel 36. The fertilizer falls into the ditch through the discharge channel 36, the fertilizer inlet 31 and the fertilizer guide pipe 14, completing the fertilization work.

[0052] The clutch engagement / disengagement assembly further optimizes the design by including a passive friction wheel 42 that is driven and connected to the input shaft 41 of the transmission 40, and an active friction wheel 43 that is rotatably connected to the transfer case 8. The active friction wheel 43 is arranged correspondingly to the passive friction wheel 42. A spline sleeve 44 is coaxially fixedly connected to the side of the active friction wheel 43 away from the passive friction wheel 42. A spline shaft is driven and connected inside the spline sleeve 44. The spline shaft is driven and connected to the power box 6. A moving drive component is provided between the active friction wheel 43 and the transfer case 8.

[0053] The scheme is further optimized. The moving drive component includes a toggle plate 46 that is rotatably sleeved on the spline sleeve 44 and a lead screw 47 that is rotatably connected in the transfer case 8. The end of the toggle plate 46 away from the spline sleeve 44 is threaded onto the lead screw 47, and a motor 48 is drivenly connected to one end of the lead screw 47.

[0054] In a further optimized design, a tenth sprocket 45 is connected to the end of the spline shaft away from the spline sleeve 44, and a fifth sprocket 21 is fixedly mounted on the first output shaft 18. The fifth sprocket 21 and the tenth sprocket 45 are connected by a chain drive.

[0055] like Figure 2 and Figure 5 As shown, during operation, the active friction wheel 43 and the passive friction wheel 42 are in contact. The power box 6 drives the active friction wheel 43 to rotate, which in turn drives the passive friction wheel 42 to drive the transmission 40 to rotate, causing the sixth sprocket 22 to rotate, thereby driving the first rotating shaft 24 and the second rotating shaft 26 to rotate, so that sowing and fertilization can be carried out simultaneously.

[0056] When the equipment moves to the edge of the working area, in order to avoid waste of grass seeds and fertilizer, the motor 48 can be controlled to drive the lead screw 47 to rotate. The lead screw 47 drives the actuating plate 46 to move away from the passive friction wheel 42 through the thread transmission, separating the active friction wheel 43 and the passive friction wheel 42. At this time, the gearbox 40 will stop rotating due to the lack of power input, thereby stopping the seeding wheel 32 and the fertilizer wheel 37, thus avoiding the sowing of fertilizer and grass seeds and avoiding waste.
