[0021] Compared with the prior art, the present invention has the following advantages and technical effects:

[0022] In operation, the straw collection and crushing device and the vehicle frame are moved together by a tractor. The straw collection and crushing device collects the straw scattered on the field surface into rows and crushes the piled straw, discharging it onto the surface. The vehicle frame moves the ditching device, deep fertilizer ditcher, main press roller, seed fertilizer ditcher, and seed fertilizer press roller. The ditching device draws trenches on the ground surface. Due to the loose soil, straw fragments on the sides of the trench fall into the trench during ditching. The deep fertilizer ditcher further deepens the trench, causing the straw fragments to fall to the bottom of the trench. The main press roller then compacts the soil, forming base fertilizer. Subsequently, the seed fertilizer ditcher opens trenches again. During the movement, the straw collection and crushing device is connected to the precision seeding device and the fertilizer box for transmission. The connection allows the precision seeding device and fertilizer box to simultaneously discharge seeds and fertilizer, which fall into the trench dug by the seed and fertilizer furrow opener. Then, the seed and fertilizer pressing roller covers and compacts the soil, completing the sowing. At this point, the seeds and fertilizer are in the same soil layer with a spacing of about 7-8 cm, and the straw fragments are in the soil layer below the seeds and fertilizer. During the seed development process, the fertilizer is used to provide fertilizer for seed germination and early growth, while the base fertilizer slowly releases its nutrients over time, providing fertilizer for the crop growth cycle. This device does not require prior clearing of straw on the ground. In just one operation, it can complete a series of tasks such as straw clearing, utilization, fertilization, seed sowing, pipe laying, and soil covering, greatly improving work efficiency and avoiding repeated soil compaction.

[0031] 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.

[0032] 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.

[0033] Example 1:

[0034] Reference Figures 1 to 4 The present invention discloses a corn stalk staggered strip tillage, fertilizer and seed belt integrated machine, including: tractor 1, and a straw collection and crushing device 2 and a frame 3 connected in sequence from front to back along the moving direction of tractor 1;

[0035] Below the chassis 3, from front to back along the direction of movement of the tractor 1, are arranged a ditching device 4, a deep fertilizer ditching device 5, a main press roller 6, a seed fertilizer ditching device 7, a seed fertilizer press roller 8, and a drip irrigation tape support frame 15.

[0036] The frame 3 is equipped with a precision seeding device 9 and a fertilizer box 10. The discharge end of the precision seeding device 9 and the fertilizer box 10 is connected to the feed end of the seed and fertilizer furrow opener 7.

[0037] The straw collection and crushing device 2 is connected to the precision seeding device 9 and the fertilizer box 10 via a transmission system.

[0038] In operation, the tractor 1 pulls the straw collection and crushing device 2 and the vehicle frame 3 together. The straw collection and crushing device 2 collects the straw scattered on the field surface into rows and crushes the piled straw, discharging it to the surface. The vehicle frame 3 moves the ditching device 4, the deep fertilizer ditching device 5, the main pressing roller 6, the seed fertilizer ditching device 7, the seed fertilizer pressing roller 8, and the drip irrigation belt support frame 15. The ditching device 4 draws trenches on the ground surface. Due to the loose soil, straw fragments on the sides of the trench fall into the trench during ditching. The deep fertilizer ditching device 5 further deepens the trench, causing the straw fragments to fall to the bottom of the trench. The main pressing roller 6 then compacts the soil, forming base fertilizer. Subsequently, the seed fertilizer ditching device 7 opens trenches again. During the movement, the straw collection and crushing device... 2. The precision seeding device 9 and the fertilizer box 10 are connected to the transmission, so that the precision seeding device 9 and the fertilizer box 10 simultaneously discharge seeds and fertilizer, which fall into the trench dug by the seed and fertilizer furrow opener 7. Then, the seed and fertilizer pressing roller 8 covers and compacts the soil to complete the sowing. At this point, the seeds and fertilizer are in the same soil layer, and the straw fragments are in the soil layer below the seeds and fertilizer. During the seed development process, the fertilizer is used to provide fertilizer for seed germination and early growth, while the base fertilizer slowly releases its fertility over time to provide fertilizer for the crop growth cycle. This device does not require the prior clearing of straw on the ground. With just one operation, it can realize a series of tasks such as straw clearing, utilization, fertilization, seed sowing, pipe laying, and soil covering, which greatly improves the operation efficiency and avoids repeated compaction of the soil.

[0039] Drip irrigation tape is wound around the drip irrigation tape support frame 15. The drip irrigation tape is automatically laid as the tractor 1 moves and is compacted by the soil covering roller 8. The drip irrigation tape is used for subsequent drip irrigation. The drip irrigation tape support frame 15 is fixed to the rear end of the vehicle frame 3. The drip irrigation tape support frame 15 includes a fixed frame and a roller on which the drip irrigation tape is wound. The roller is rotatably connected to the fixed frame. The laying of the drip irrigation tape and the drip irrigation tape are both existing technologies and will not be described in detail here.

[0040] The precision seeding device 9 is existing technology and will not be described in detail here.

[0041] Further optimization of the scheme: the straw collection and crushing device 2 includes a connecting shaft 201 for connecting to the tail end of the tractor 1. One end of the inclined beam 202 is hinged to both ends of the connecting shaft 201. The two inclined beams 202 are arranged in a figure-eight shape. The open ends of the two inclined beams 202 are located close to the tractor 1. The other ends of the two inclined beams 202 are fixed to the frame 204.

[0042] The inclined beam 202 is provided with grass-removing sections at equal intervals along its length;

[0043] A crushing box 206 is fixedly connected to the bottom of the frame 204. A crushing section is provided inside the crushing box 206. The feed end of the crushing section is set towards the tractor 1. Support wheels 205 are rotatably connected to both sides of the crushing box 206. The support wheels 205 are connected to the crushing section in a transmission connection.

[0044] Any of the support wheels 205 is connected to the precision seeding device 9 and the fertilizer box 10 via a transmission.

[0045] The scheme is further optimized. The grass-removing part includes a grass-removing wheel 203, which is rotatably mounted on the inclined beam 202. The grass-removing wheel 203 is used to move the straw on the ground to between the two inclined beams 202.

[0046] The straw-pulling wheel 203 rotates by the friction between the tractor 1 and the ground, and when it rotates, it pulls the straw between the two inclined beams 202.

[0047] The further optimized scheme includes a crushing section comprising a crushing roller 214 and a crushing blade roller 212 rotatably disposed inside the crushing box 206. The crushing roller 214 is disposed near the feed end of the crushing box 206, and the two ends of the crushing roller 214 are respectively connected to two support wheels 205.

[0048] The rotating crushing roller 212 is positioned near the discharge end of the crushing box 206, and the rotating crushing roller 212 is connected to any support wheel 205 via a speed-changing unit.

[0049] In a further optimized design, the transmission unit includes a multi-stage sprocket 207, which is rotatably mounted on the outer wall of the crushing chamber 206. The multi-stage sprocket 207 is axially connected to either end of the rotating crushing roller 212. A gearbox 208 is located below the multi-stage sprocket 207, and the fixed end of the gearbox 208 is fixedly connected to the outer wall of the crushing chamber 206. A first chain 210 is sleeved on the multi-stage sprocket 207. After passing through the gearbox 208, the first chain 210 is sleeved on the outside of the main sprocket 209. The main sprocket 209 is axially connected to the corresponding support wheel 205.

[0050] To further optimize the design, an arc-shaped baffle 211 is provided above the rotating crushing roller 212, and the arc-shaped baffle 211 is fixed to the inner wall of the crushing box 206.

[0051] To further optimize the design, a fixed crushing blade 213 is provided between two adjacent blades of the rotating crushing roller 212, and the fixed crushing blade 213 is fixedly connected to the inner wall of the bottom of the crushing box 206.

[0052] To further optimize the design, a first ramp 215 is provided at the bottom of the crushing box 206, with the high end of the first ramp 215 located near the feed end of the crushing box 206.

[0053] To further optimize the design, a second ramp 216 is fixed to the bottom of the feed end side of the crushing box 206, and the high end of the second ramp 216 is set close to the feed end of the crushing box 206.

[0054] In use, after several straw-pulling wheels 203 gather the straw between the two inclined beams 202, under the drag of the tractor 1, the bottom of the second inclined slope 216 first contacts the gathered straw pile, and under the action of the second inclined slope 216, it enters the crushing box 206. At the same time, because the support wheel 205 is in contact with the ground, the support wheel 205 will start to rotate as it moves. The support wheel 205 drives the crushing roller 214 to crush the straw and move it towards the discharge end. The main sprocket 209, which is shaft-connected to the support wheel 205, will also rotate with the support wheel 202. The first chain 210 rotates together with the multi-stage sprocket 207 via the gearbox 208, which in turn drives the rotating crushing roller 212 to rotate. The multi-stage sprocket 207 has several coaxially fixed sprockets with different gear ratios. The gearbox 208 can switch the position of the first chain 210 on the multi-stage sprocket 207 to change the transmission ratio, so that the rotation speed of the crushing roller 214 and the rotating crushing roller 212 are inconsistent. The gearbox 208 can also adjust the rotation speed of the rotating crushing roller 212 to change the crushing effect.

[0055] The derailleur 208 is preferably a TX35 rear derailleur, and is used in conjunction with an M2010 shifter, which is fixed to the frame 204.

[0056] The first ramp 215 at the bottom of the crushing box 206 facilitates the movement of materials to the discharge end. The arc-shaped baffle 211 above the rotating crushing roller 212 can block the rolled-up straw, allowing it to re-enter the working range of the rotating crushing roller 212 to participate in crushing. The fixed crushing blade 213 between two adjacent blades of the rotating crushing roller 212 can improve the crushing effect.

[0057] The trenching device 4 includes several deep loosening shovels arranged side by side, used to extend into the ground surface and create trenches during movement. The number and position of the deep fertilization trench openers 5 are matched with the deep loosening shovels. The two ends of the main pressing roller 6 are respectively rotatably connected to the bottom end of the rotating bracket, and the top end of the rotating bracket is hinged to the frame 3. The movable end of the hydraulic telescopic rod is hinged to the middle of the rotating bracket, and the fixed end of the hydraulic telescopic rod is hinged to the frame 3. The downward pressure of the main pressing roller 6 can be adjusted by extending and retracting the hydraulic telescopic rod. There is one main pressing roller 6, and its width matches the width of the frame 3.

[0058] The number and position of the seed and fertilizer furrow openers 7 are matched with those of the deep fertilizer furrow openers 5, and they are rotatably set at the bottom of the frame 3. The number of precision seeding devices 9 is matched with that of the seed and fertilizer furrow openers 7. The precision seeding device 9 includes at least a box, a seeding tray, a seeding shaft, and a seed protection belt. Two adjacent seeding shafts are connected together, which can make multiple seeding trays rotate at the same time.

[0059] A third sprocket 13 is axled on the sowing shaft located on either side. One end of a chain is fitted on the third sprocket 13, and the other end of the chain is fitted on the second sprocket 12. The second sprocket 12 is rotatably connected to the top side of the corresponding furrowing device 4 and is connected to the first sprocket 11 via chain drive. The first sprocket 11 is axled on the support wheel 205 on the corresponding side.

[0060] The number of fertilizer boxes 10 matches the number of precision seeding devices 9, and they are fixed on the frame 3. Their structure is the same as that of the precision seeding device 9. The seeding shafts of two adjacent fertilizer boxes 10 are connected by shafts, and a fourth sprocket 14 is connected to the seeding shaft of the fertilizer box 10 located on the side. The fourth sprocket 14 is connected to the third sprocket 13 through a chain.

[0061] With this configuration, the rotation of the support wheel 205 can drive the first sprocket 11 to rotate, and then drive the second sprocket 12, the third sprocket 13 and the fourth sprocket 14 to rotate together through chain transmission, thereby driving each precision seeding device 9 and each fertilizer box 10 to sow and fertilize.

[0062] The structure and configuration of the precision seeding device 9 and the fertilizer box 10 are both existing technologies, and the transmission method via the support wheel 205 and sprocket chain is also existing technology, which will not be described in detail here.

[0063] The seed and fertilizer pressing roller 8 is rotatably set at the rear end of the frame 3 in the direction of movement. Its width matches the width of the frame 3. It is used to cover the seed hole with soil after sowing and fertilization are completed.

[0064] Example 2:

[0065] refer to Figures 5 to 6The difference between this embodiment and Embodiment 1 is that the trenching device 4 includes a vertical plate 401, which is fixedly connected to the frame 3. A fixed end of a conveyor belt 402 is fixedly connected to the bottom of the vertical plate 401. The movable end of the conveyor belt 402 is located on the side of the vertical plate 401 near the discharge end of the crushing box 206, and the conveyor belt 402 is inclined. The bottom end of the conveyor belt 402 is near the discharge end of the crushing box 206. The feed end of the conveyor belt 402 is connected to the discharge end of the crushing box 206. Side rails 403 are provided on the front and rear sides of the conveyor belt 402, and the side rails 403 are fixedly connected to the vertical plate 401. The discharge end of the conveyor belt 402 is connected to a material gathering trough 406, which is located at the bottom of the vertical plate 401. The bottom of the material gathering trough 406 is connected to the top of several hollow deep loosening shovels 405. The hollow deep loosening shovels 405 are evenly spaced, and a material gathering slope 404 is provided between two adjacent hollow deep loosening shovels 405. The material gathering slope 404 is fixed to the bottom inner wall of the material gathering trough 406. Another material gathering slope 404 is fixed between the top of the hollow deep loosening shovel 405 located at the edge and the side wall of the corresponding material gathering trough 406. The material gathering slope 404 is used to move the straw fragments to the top of the hollow deep loosening shovel 405.

[0066] After the crushed straw fragments are discharged from the crushing box 206, they enter the conveyor belt 402. Under the lifting action of the conveyor belt 402, they enter the material gathering trough 406, and from the material gathering trough 406, they enter each hollow deep loosening shovel 405. The material gathering slope 404 allows the straw fragments to slide along the slope until they slide into the corresponding hollow deep loosening shovel 405, which can prevent material accumulation. At the same time, the bottom end of the hollow deep loosening shovel 405 extends into the soil surface, which plays a role in trenching. The straw fragments will be directly transported to the bottom of the trench through the hollow part of the hollow deep loosening shovel 405. Compared with sliding down the slope of the trench to the bottom, the above-mentioned configuration can make the straw fragments in the trench more abundant, resulting in better base fertilizer effect.
