Green manure crop rotation cultivation device and method for saline-alkali land improvement

Abstract

The present invention provides a green manure crop rotation cultivation device and method for improving saline-alkali land, which relates to the technical field of green manure crop cultivation, including: a mounting bracket, a furrowing mechanism, a driving mechanism, a watering mechanism, and a sowing mechanism; the furrowing mechanism includes two connecting brackets fixedly arranged at the bottom of the mounting bracket, and the two connecting brackets are rotatably connected to a rotating shaft on opposite sides. This scheme ultimately realizes that the valve is intermittently pushed by the pushing frame through the left and right movement of the horizontal plate, so that the water in the water tank is intermittently discharged into the groove through the outlet pipe. The two connecting plates will simultaneously drive the two gear plates to move left and right during the movement process, thereby causing the gears to rotate back and forth. When the gears rotate, the receiving hopper is driven to rotate back and forth through the transmission shaft, so that the seeds in the seed box intermittently fall into the block watering position in the groove. When planting sesbania seeds, there is no need to dig furrows and irrigate the saline-alkali land in advance, which effectively reduces the workload of farmers and improves the cultivation efficiency of sesbania seeds.

Description

Technical Field

[0001] The present invention relates to the technical field of green manure crop cultivation, and in particular to a green manure crop rotation cultivation device and method for improving saline-alkali land. Background Art

[0002] The cultivation of green manure crops is a systematic process that requires rational planning and management tailored to specific regions, crop types, and soil conditions. In saline-alkali land reclamation, green manure crops such as sesbania, hairy vetch, occidentalis, or alfalfa are often selected for rotation. Rotating these green manure crops effectively improves soil structure and fertility, creating a favorable environment for subsequent agricultural production.

[0003] In the related art, the green manure crop rotation for improving saline-alkali land usually adopts a rotation model of sesbania and sunflower. This rotation method involves planting sesbania in the first season, then plowing and fertilizing, and then planting sunflower. Sesbania as green manure can improve soil structure, increase soil fertility, and reduce soil salt accumulation. Sunflower has a high economic value and can grow well in the improved soil, thereby improving the economic benefits of the land. However, this rotation model uses furrow sowing for sesbania, and before rainwater can press salt on the saline-alkali soil, it is necessary to dig furrows and irrigate the saline-alkali land before planting. When using existing cultivation equipment to cultivate sesbania in furrow sowing, it is necessary to dig furrows and irrigate the saline-alkali land in advance, which undoubtedly greatly increases the labor of farmers and reduces the cultivation efficiency of sesbania. In addition, this planting method requires a large amount of water, which is a serious waste of water resources.

[0004] Therefore, it is necessary to provide a green manure crop rotation cultivation device and method for saline-alkali land improvement to solve the above technical problems. Summary of the Invention

[0018] A green manure crop rotation cultivation method for saline-alkali land improvement comprises the following steps:

[0019] S1: soil and seed treatment;

[0020] Deeply plow the saline-alkali soil and remove weeds;

[0021] Before sowing in furrows, soak the sesbania seeds in 60℃ warm water 3 times the volume of the seeds, stir for 2-3 minutes, cool and dry, or roll them twice with a rice mill, then soak them in 50-60℃ warm water for a day and night, or soak early-maturing hard-grain seeds in 90℃ hot water, then wash them with cold water;

[0022] S2: Planting and cultivation;

[0023] The driving motor drives the rotating shaft and the trenching knife group to rotate, and the trenching knife group is used to trench the saline-alkali soil. When the rotating shaft rotates, it will drive the two rotating cams to rotate at the same time. Under the action of the first tension spring, the top of the swing frame will swing back and forth, and the top rotating wheel will drive the sliding seat to slide left and right on the slide rail surface. When the sliding seat slides, it will drive the two connecting plates and the cross plate to move left and right. The left and right movement of the cross plate drives the pushing frame to intermittently push the valve, so that the water in the water tank is intermittently discharged into the groove through the outlet pipe. During the movement, the two connecting plates will simultaneously drive the two gear plates to move left and right, so that the gears rotate back and forth. When the gears rotate, the receiving hopper is driven to rotate back and forth through the transmission shaft, so that the seeds in the seed box intermittently fall into the block watering position in the groove;

[0024] When the device moves, it will use the covering plate to cover the sesbania seeds. The rotating shaft rotates and uses the first pulley, belt and second pulley to drive the crushing roller and crushing knife group to rotate, crushing the wheat straw. The crushed wheat straw will be discharged through the discharge box to the top of the sesbania seeds covered with soil. The wheat straw covering reduces the evaporation of soil moisture and forms a physical barrier on the soil surface.

[0025] The driving shaft rotates, and under the cooperation of the first bevel gear and the second bevel gear, drives the fertilizer spreading disc and the fertilizer spreading knife group to rotate, thereby spreading the fertilizer on the surface of the saline-alkali soil to fertilize the saline-alkali soil;

[0026] S3: Sesbania sesbania pressed green;

[0027] The driving shaft rotates, and with the cooperation of the third bevel gear and the fourth bevel gear, the rotating rod and the cutting knife group are driven to rotate, so that the cutting knife group can cut the sesbania from the bottom;

[0028] The blades on the surface of the trenching knife group are removed and replaced with cutting blades, and the belt is removed. The cutting blades are driven to rotate by the rotating shaft and the cutter disc through the rotation of the drive motor, thereby cutting the cut sesbania into small segments;

[0029] The covering mechanism is disassembled, and then the pressing roller is installed on the two walking wheels using a connecting sleeve on the opposite side of the two rotating seats. The movement of the device drives the pressing roller to press the field sesbania cut into small sections, thereby improving the soil structure of the saline-alkali land and facilitating the subsequent planting of sunflowers.

[0030] Compared with related technologies, the green manure crop rotation cultivation device and method for saline-alkali land improvement provided by the present invention have the following beneficial effects:

[0031] The two rotating cams are driven to rotate by the rotating shaft, and the top of the swing frame is caused to swing back and forth left and right under the action of the first tension spring, and the sliding seat is driven to slide left and right on the slide rail surface by the top rotating wheel. When the sliding seat slides, it will drive the two connecting plates and the cross plate to move left and right. The left and right movement of the cross plate drives the push frame to intermittently push the valve, so that the water in the water tank is intermittently discharged into the groove through the outlet pipe. The two connecting plates will simultaneously drive the two gear plates to move left and right during the movement, so that the gears rotate back and forth. When the gears rotate, the receiving hopper is driven to rotate back and forth through the transmission shaft, so that the seeds in the seed box intermittently fall into the block watering position in the groove. When planting sesbania seeds, there is no need to dig trenches and irrigate saline-alkali land in advance, which effectively reduces the workload of farmers and improves the cultivation efficiency of sesbania seeds. In addition, this method consumes less water, avoiding the problem of waste of water resources caused by traditional methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0061] The invention provides a green manure crop rotation cultivation device and method for improving saline-alkali land.

[0062] First embodiment:

[0063] See also Figures 1 to 10 , a green manure crop rotation cultivation device for saline-alkali land improvement, comprising: a mounting bracket 1, a furrowing mechanism 2, a driving mechanism 3, a watering mechanism 4 and a sowing mechanism 5;

[0064] The trenching mechanism 2 includes two connecting brackets 21 fixedly mounted on the bottom of the mounting bracket 1. A rotating shaft 22 is rotatably connected to opposite sides of the two connecting brackets 21. Three trenching blade groups 23 are fixedly mounted on the surface of the rotating shaft 22. A protective cover 24 is fixedly mounted on the inner side of the mounting bracket 1 and on the top of the trenching blade groups 23. A driving motor 25 for driving the rotating shaft 22 is provided on the back side of the rear connecting bracket 21.

[0065] Please combine Figure 3: Start the drive motor 25, and the rotation of the drive motor 25 drives the rotating shaft 22 to rotate, and the rotation of the rotating shaft 22 drives the trenching cutter group 23 to rotate, so that the trenching cutter group 23 rotates to trench the saline-alkali soil;

[0066] Preferably, the trenching knife group 23 is composed of a knife disc and a blade, and the knife disc and the blade are connected by bolts. The blade can be replaced after the bolts are removed;

[0067] The driving mechanism 3 includes two swing frames 31 rotatably connected to the inner side of the mounting bracket 1, and two rotating wheels 32 are rotatably connected to the opposite sides of the two swing frames 31. Two mounting seats 33 are fixed at the bottom of the mounting bracket 1, and a slide rail 34 is fixed on the separated side of the two mounting seats 33. The surfaces of the two slide rails 34 are slidably connected to sliding seats 35. The right sides of the two sliding seats 35 are fixed with connecting plates 36, and the tops of the two connecting plates 36 are fixed with gear plates 37. Two rotating cams 38 are fixed on the surface of the rotating shaft 22. A first tension spring 39 is provided on the separated side of the two swing frames 31, and the bottom ends of the two first tension springs 39 are respectively fixedly connected to the opposite side of the two connecting brackets 21. A protective plate 310 is fixed on the separated side of the two connecting plates 36.

[0068] Please combine Figures 3 to 5 When the rotating shaft 22 rotates, it drives the two rotating cams 38 to rotate. When the rotating cams 38 rotate, under the action of the first tension spring 39, the bottom rotating wheel 32 is in close contact with the surface of the rotating cam 38. Then, the rotation of the rotating cam 38 causes the top of the swing frame 31 to swing back and forth left and right. When the swing frame 31 swings left and right, the top rotating wheel 32 drives the sliding seat 35 to slide left and right on the surface of the slide rail 34. The left and right sliding of the sliding seat 35 drives the connecting plate 36 and the gear plate 37 to move left and right.

[0069] Preferably, the protrusions on the surface of the sliding seat 35 located on both sides of the rotating wheel 32 can be removed. When the bolts inside the protrusions are removed together with the protrusions, the position of the sliding seat 35 will not change when the swing frame 31 drives the top rotating wheel 32 to swing.

[0070] The watering mechanism 4 includes a base 41 fixedly mounted on one side opposite to the two mounting seats 33. A water tank 42 is provided on the top of the base 41. The bottom of the water tank 42 is connected to three water outlet pipes 43. The surfaces of the three water outlet pipes 43 are each provided with a valve 44. The surfaces of the three valves 44 are each provided with a second tension spring 45. The top ends of the three second tension springs 45 are fixedly connected to the bottom of the base 41. A horizontal plate 46 is fixedly mounted on the opposite side of the two connecting plates 36. Three push racks 47 are fixedly mounted on the right side of the horizontal plate 46.

[0071] Please combine Figures 6 to 8 When the two sliding seats 35 drive the two connecting plates 36 to move rightward, the movement of the two connecting plates 36 drives the cross plate 46 and the three pushing frames 47 to move rightward. After the pushing frames 47 move to a certain position to the right, they come into contact with the valve handle 44 and push the valve handle 44 to the right, causing the second tension spring 45 to stretch. The rotation of the valve handle 44 allows the water in the water tank 42 to be drained through the water outlet pipe 43, and finally the water is discharged into the opened groove through the water outlet pipe 43.

[0072] Furthermore, when the two sliding seats 35 drive the two connecting plates 36 to return to the left, the movement of the two connecting plates 36 drives the cross plate 46 and the three pushing frames 47 to move to the left, and the second tension spring 45 is stretched to reset the valve handle 44, thereby stopping water discharge into the groove.

[0073] Preferably, when the water is discharged into the groove through the outlet pipe 43, the device is in a mobile state, so that due to the intermittent drainage of the outlet pipe 43, block-shaped watering positions will appear in the groove;

[0074] The sowing mechanism 5 includes three seed boxes 51 fixed to the right side of the water tank 42. The bottom of the three seed boxes 51 is fixed with a discharge hopper 52. The bottom of the three discharge hoppers 52 is connected to a discharge pipe 53. The inner sides of the three discharge hoppers 52 are longitudinally connected to a transmission shaft 54. The surface of the transmission shaft 54 ​​and the inner sides of the three discharge hoppers 52 are fixed with a receiving hopper 55. Gears 56 are fixed at both ends of the transmission shaft 54. The two gears 56 are respectively engaged with the two gear plates 37.

[0075] Please combine Figure 9 and Figure 10 When the two sliding seats 35 drive the two connecting plates 36 to move rightward, the two connecting plates 36 will simultaneously drive the two gear plates 37 to move rightward. The movement of the two gear plates 37 will drive the two gears 56 to rotate counterclockwise. The two gears 56 drive the receiving hopper 55 to rotate counterclockwise through the transmission shaft 54, so that the sesbania seeds in the seed box 51 can fall into the receiving hopper 55.

[0076] Furthermore, when the two sliding seats 35 drive the two connecting plates 36 to reset to the left, the two connecting plates 36 will drive the two gear plates 37 to move to the left, and the movement of the two gear plates 37 will drive the two gears 56 to rotate clockwise. The two gears 56 drive the receiving hopper 55 to rotate clockwise through the transmission shaft 54, so that the field sesbania seeds fall into the groove through the discharge hopper 52 and the discharge pipe 53.

[0077] Preferably, when the sesbania seeds fall into the groove through the discharge hopper 52 and the discharge pipe 53, the device is in a moving state, so the position of the sesbania seeds when they fall will be located at the block watering position in the groove, and the sesbania seeds are also distributed in a hole shape;

[0078] The surfaces of the two top rotating wheels 32 are respectively located on the inner sides of the two sliding seats 35 , and the surfaces of the two bottom rotating wheels 32 are respectively fitted with the surfaces of the two rotating cams 38 via the first tension springs 39 .

[0079] The three water outlet pipes 43 are respectively located on the left side of the three discharge pipes 53, and the bottom ends of the three water outlet pipes 43 and the discharge pipes 53 are respectively located on the right side of the three grooving knife groups 23. The surfaces of the three receiving hoppers 55 are respectively provided with through grooves, and the bottoms of the inner walls of the three seed boxes 51 are respectively provided with through grooves for use with the three receiving hoppers 55.

[0080] In this embodiment, unlike the existing sesbania cultivation device, the present case drives the rotating shaft 22 and the furrowing knife group 23 to rotate by the driving motor 25, and then uses the furrowing knife group 23 to furrow the saline-alkali soil. When the rotating shaft 22 rotates, it will simultaneously drive the two rotating cams 38 to rotate, and under the action of the first tension spring 39, the top of the swing frame 31 will swing back and forth left and right, and the top rotating wheel 32 will drive the sliding seat 35 to slide left and right on the surface of the slide rail 34. When the sliding seat 35 slides, it will drive the two connecting plates 36 and the cross plate 46 to move left and right, and the left and right movement of the cross plate 46 will drive the pushing frame 47 to intermittently push the valve 44, so that the water in the water tank 42 is intermittently discharged into the groove through the outlet pipe 43, and the two connecting plates 36 will simultaneously drive the two gear plates 37 to move left and right during the movement, so that the gear 56 rotates back and forth, and the gear 56 drives the receiving hopper 55 to rotate back and forth through the transmission shaft 54 ​​when rotating, so that the seeds in the seed box 51 intermittently fall on the block watering position in the groove. When planting sesbania seeds, there is no need to dig trenches and irrigate the saline-alkali land in advance, which effectively reduces the workload of farmers and improves the cultivation efficiency of sesbania seeds. In addition, this method consumes less water and avoids the problem of waste of water resources caused by traditional methods.

[0081] Second embodiment:

[0082] See also Figure 2 、 Figures 11 to 13A crushing mechanism 6 is fixedly provided on the right side of the top of the mounting bracket 1. The crushing mechanism 6 includes a crushing box 61 fixedly provided on the right side of the top of the mounting bracket 1. The right side of the top of the crushing box 61 is connected to a discharge hopper 62. The bottom of the crushing box 61 is connected to three discharge boxes 63. A crushing roller 64 is longitudinally rotatably connected to the opposite side of the inner wall of the crushing box 61. A plurality of crushing knife groups 65 are fixed on the surface of the crushing roller 64. A first pulley 66 is fixedly provided at the front end of the rotating shaft 22. A second pulley 67 is fixedly provided at the front end of the crushing roller 64 and located on the outside of the crushing box 61. A belt 68 is sleeved on the surface of the first pulley 66 and the second pulley 67. Guide plates 69 are fixedly provided on both sides of the inner wall of the crushing box 61.

[0083] Please combine Figure 2 、 Figure 11 and Figure 12 : When the rotating shaft 22 drives the ditching knife group 23 to ditch the saline-alkali land, the rotating shaft 22 will simultaneously drive the first pulley 66 to rotate, and the first pulley 66 will drive the second pulley 67 to rotate through the belt 68. The rotation of the second pulley 67 will drive the crushing roller 64 and the crushing knife group 65 to rotate. After the straw is put into the crushing box 61 through the discharge hopper 62, the straw is crushed by the rotation of the crushing knife group 65, and the crushed straw will be discharged through the discharge box 63.

[0084] A soil covering mechanism 7 is fixedly provided on the surface of the discharge box 63. The soil covering mechanism 7 includes two sliding sleeves 71 fixedly provided on the surface of the discharge box 63. Connecting rods 72 are slidably connected to the inner sides of the two sliding sleeves 71. Covering plates 73 are fixedly provided on opposite sides of the two connecting rods 72.

[0085] Please combine Figure 13 : When the device moves, it will drive the covering plate 73 to move. Through the movement of the covering plate 73, the soil produced after the trenching is pushed into the trench to cover the sesbania seeds;

[0086] Preferably, the sliding sleeve 71 is connected to the connecting rod 72 via an insert rod. After the insert rod is pulled out, the connecting rod 72 and the covering plate 73 can be disassembled or the height of the covering plate 73 can be adjusted.

[0087] In this embodiment, when the device moves, it will drive the covering plate 73 to move at the same time, so that the covering plate 73 can push the soil generated by the trenching into the trench to cover the sesbania seeds. The first pulley 66, the belt 68 and the second pulley 67 are used to drive the crushing roller 64 and the crushing knife group 65 to rotate by the rotation of the rotating shaft 22, so as to crush the wheat straw. The crushed wheat straw will be discharged to the top of the sesbania seeds after covering with soil through the discharge box 63. By covering the wheat straw, the evaporation of soil moisture is reduced, and a physical barrier is formed on the soil surface, thereby inhibiting the salt from rising to the surface with the moisture, ensuring the smooth germination and growth of the sesbania seeds, and the wheat straw will gradually decompose over time, thereby increasing the content of organic matter in the soil, providing nutrients for the growth of sesbania or sunflowers, and increasing the yield of sesbania or sunflowers.

[0088] Third embodiment:

[0089] See also Figure 14 and Figure 15 , a fertilizing mechanism 8 is fixedly provided on the left side of the mounting bracket 1, and the fertilizing mechanism 8 includes two fertilizing boxes 81 fixedly provided on the left side of the mounting bracket 1, and the bottoms of the two fertilizing boxes 81 are rotatably connected to fertilizer spreading discs 82, and the tops of the two fertilizer spreading discs 82 are fixedly provided with fertilizer spreading knife groups 83, and the bottoms of the two fertilizer spreading discs 82 are keyway-connected with first bevel gears 84, and two mounting baffles 85 are fixedly provided on the left side of the top of the mounting bracket 1, and the opposite sides of the two mounting baffles 85 are rotatably connected to a drive shaft 86, and two second bevel gears 87 are fixedly provided on the surface of the drive shaft 86, and the two second bevel gears 87 are respectively meshed with the two first bevel gears 84, and a fertilizer spreading motor 88 for driving the drive shaft 86 to rotate is provided on the front side of the mounting baffle 85;

[0090] Please combine Figure 14 : Start the fertilizer spreading motor 88, and the driving shaft 86 is driven by the rotation of the fertilizer spreading motor 88 to rotate. The driving shaft 86 rotates and drives the two second bevel gears 87 to rotate. The rotation of the two second bevel gears 87 drives the two first bevel gears 84 to rotate. The rotation of the two first bevel gears 84 respectively drives the two fertilizer spreading discs 82 and the fertilizer spreading knife group 83 to rotate, thereby spreading the fertilizer on the soil surface without furrows;

[0091] Preferably, through subsequent trenching and covering work, the soil covering the surface of the sesbania seeds can be a mixture of soil and fertilizer, which is conducive to the downward decomposition of the fertilizer to provide nutrients to the sesbania seeds. When the first bevel gear 84 is moved upward, the rotation of the second bevel gear 87 will not drive the fertilizer spreading disc 82 to rotate through the first bevel gear 84.

[0092] A pressing mechanism 9 is fixedly provided on the inner side of the left side of the mounting bracket 1. The pressing mechanism 9 includes a truss 91 fixedly provided on the inner side of the left side of the mounting bracket 1. A rotating rod 92 is vertically rotatably connected to the inner side of the truss 91. A cutting knife group 93 is fixedly provided at the bottom end of the rotating rod 92. A third bevel gear 94 is connected to the top keyway of the rotating rod 92. A fourth bevel gear 95 is fixedly provided on the surface of the driving shaft 86. The fourth bevel gear 95 is meshed with the third bevel gear 94.

[0093] Please combine Figure 15 When the fertilizer spreading motor 88 rotates, it will also drive the fourth bevel gear 95 to rotate. The rotation of the fourth bevel gear 95 will drive the third bevel gear 94 and the rotating rod 92 at the bottom to rotate. The rotation of the rotating rod 92 will drive the cutting knife group 93 to rotate. When the sesbania has grown to the point where it can be pressed, the rotation of the cutting knife group 93 can cut the sesbania from the bottom, making it easier to carry out the subsequent pressing work.

[0094] Preferably, the last third bevel gear 94 and the last first bevel gear 84 share a second bevel gear 87. After the third bevel gear 94 is moved downward on the surface of the rotating rod 92, the rotation of the fourth bevel gear 95 will not drive the rotating rod 92 to rotate through the third bevel gear 94.

[0095] A traction frame 10 is fixedly provided on the left side of the truss 91 , and two rotating seats 11 are fixedly provided on the right side of the bottom of the mounting bracket 1 . Travel wheels 12 are rotatably connected to the separated sides of the two rotating seats 11 .

[0096] In this embodiment, by rotating the drive shaft 86, with the cooperation of the first bevel gear 84 and the second bevel gear 87, the fertilizer spreading disc 82 and the fertilizer spreading knife group 83 can be driven to rotate, thereby spreading the fertilizer on the surface of the saline-alkali soil. With the cooperation of the third bevel gear 94 and the fourth bevel gear 95, the rotating rod 92 and the cutting knife group 93 can be driven to rotate, so that the cutting knife group 93 can be used to cut the field arable from the bottom, which is convenient for the subsequent green pressing work.

[0097] Please refer to the Figures 1 to 15 The working principle of the green manure crop rotation cultivation device for saline-alkali land improvement provided by the present invention is as follows:

[0098] Step S1: Connect the device to the traction mechanism using the traction frame 10, then place the processed sesbania seeds into the seed box 51, move the device to the planting site via the traction mechanism, drive the motor 25, and rotate the rotating shaft 22 by the driving motor 25. The rotating shaft 22 rotates and drives the furrowing cutter group 23 to rotate, thereby using the furrowing cutter group 23 to rotate and furrow the saline-alkali soil;

[0099] When the rotating shaft 22 rotates, it drives the two rotating cams 38 to rotate. When the rotating cam 38 rotates, under the action of the first tension spring 39, the bottom rotating wheel 32 is pressed against the surface of the rotating cam 38, and then the top of the swing frame 31 swings back and forth left and right through the rotation of the rotating cam 38. When the swing frame 31 swings left and right, the top rotating wheel 32 drives the sliding seat 35 to slide left and right on the surface of the slide rail 34. The left and right sliding of the sliding seat 35 drives the connecting plate 36 and the gear plate 37 to move left and right.

[0100] In step S2, when the two sliding seats 35 drive the two connecting plates 36 to move rightward, the movement of the two connecting plates 36 drives the cross plate 46 and the three pushing frames 47 to move rightward. After the pushing frames 47 move rightward to a certain position, they contact the valve 44 handle and push the valve 44 handle to the right, causing the second tension spring 45 to stretch. The rotation of the valve 44 handle causes the water in the water tank 42 to be drained through the water outlet pipe 43 and finally discharged into the opened groove through the water outlet pipe 43.

[0101] When the two sliding seats 35 drive the two connecting plates 36 to return to the left, the movement of the two connecting plates 36 drives the cross plate 46 and the three pushing frames 47 to move to the left, and the second tension spring 45 is stretched to reset the valve handle 44, thereby stopping the drainage into the groove;

[0102] Step S3: When the two sliding seats 35 drive the two connecting plates 36 to move rightward, the two connecting plates 36 will simultaneously drive the two gear plates 37 to move rightward. The movement of the two gear plates 37 will drive the two gears 56 to rotate counterclockwise. The two gears 56 drive the receiving hopper 55 to rotate counterclockwise via the transmission shaft 54, so that the sesbania seeds in the seed box 51 can fall into the receiving hopper 55.

[0103] When the two sliding seats 35 drive the two connecting plates 36 to return to the left, the two connecting plates 36 will drive the two gear plates 37 to move leftward. The movement of the two gear plates 37 drives the two gears 56 to rotate clockwise. The two gears 56 drive the receiving hopper 55 to rotate clockwise through the transmission shaft 54, so that the sesbania seeds pass through the discharge hopper 52 and the discharge pipe 53 and fall into the groove.

[0104] Step S4: When the device moves, it drives the cover plate 73 to move. The movement of the cover plate 73 pushes the soil generated after the trenching into the trench to cover the sesbania seeds.

[0105] When the rotating shaft 22 drives the trenching knife group 23 to trench the saline-alkali land, the rotating shaft 22 will simultaneously drive the first pulley 66 to rotate, and the first pulley 66 will drive the second pulley 67 to rotate through the belt 68. The rotation of the second pulley 67 will drive the crushing roller 64 and the crushing knife group 65 to rotate. After the wheat straw is put into the crushing box 61 through the discharge hopper 62, the wheat straw is crushed by the rotation of the crushing knife group 65. The crushed wheat straw will be discharged through the discharge box 63 to the top of the sesbania seeds after covering with soil. By covering the wheat straw, the evaporation of soil moisture is reduced, and a physical barrier is formed on the soil surface.

[0106] Step S5: After the third bevel gear 94 is moved downward on the surface of the rotating rod 92, the fertilizer spreading motor 88 rotates to drive the drive shaft 86, which in turn drives the two second bevel gears 87 to rotate. The rotation of the two second bevel gears 87 drives the two first bevel gears 84 to rotate. The rotation of the two first bevel gears 84 respectively drives the two fertilizer spreading discs 82 and the fertilizer spreading knife group 83 to rotate, thereby spreading the fertilizer on the soil surface without furrows.

[0107] Step S6: When the sesbania needs to be pressed, the first bevel gear 84 is moved upward, and the fourth bevel gear 95 is driven to rotate by the fertilizer spreading motor 88. The fourth bevel gear 95 rotates and drives the third bevel gear 94 and the rotating rod 92 at the bottom to rotate. The rotation of the rotating rod 92 drives the cutting knife group 93 to rotate. The rotation of the cutting knife group 93 can cut the sesbania from the bottom, which is convenient for the subsequent pressing work.

[0108] The blades on the surface of the trenching knife group 23 are removed and replaced with cutting blades. The cutting blades are driven to rotate by the rotating shaft 22 and the cutter disc through the rotation of the driving motor 25, so that the cut sesbania can be divided into small segments;

[0109] The covering mechanism 7 is disassembled, and then the pressing roller is installed on the two walking wheels 12 using a connecting sleeve on the opposite side of the two rotating seats 11. The movement of the device drives the pressing roller to press the field sesbania cut into small sections, thereby improving the soil structure of the saline-alkali land and facilitating the subsequent planting of sunflowers.

[0110] Please refer to the Figures 1 to 15 A green manure crop rotation cultivation method for saline-alkali land improvement comprises the following steps:

[0111] S1: soil and seed treatment;

[0112] Deeply plow the saline-alkali soil and remove weeds;

[0113] Before sowing in furrows, soak the sesbania seeds in 60℃ warm water 3 times the volume of the seeds, stir for 2-3 minutes, cool and dry, or roll them twice with a rice mill, then soak them in 50-60℃ warm water for a day and night, or soak early-maturing hard-grain seeds in 90℃ hot water, then wash them with cold water;

[0114] S2: Planting and cultivation;

[0115] The driving motor 25 drives the rotating shaft 22 and the trenching knife group 23 to rotate, and the trenching knife group 23 is used to trench the saline-alkali soil. When the rotating shaft 22 rotates, it will simultaneously drive the two rotating cams 38 to rotate. Under the action of the first tension spring 39, the top of the swing frame 31 will swing back and forth, and the top rotating wheel 32 will drive the sliding seat 35 to slide left and right on the surface of the slide rail 34. When the sliding seat 35 slides, it will drive the two connecting plates 36 and the cross plate 46 to move left and right. The left and right movement of the cross plate 46 drives the pushing frame 47 to intermittently push the valve 44, so that the water in the water tank 42 is intermittently discharged into the groove through the outlet pipe 43. During the movement, the two connecting plates 36 will simultaneously drive the two gear plates 37 to move left and right, causing the gear 56 to rotate back and forth. When the gear 56 rotates, it drives the receiving hopper 55 to rotate back and forth through the transmission shaft 54, so that the seeds in the seed box 51 intermittently fall into the block watering position in the groove;

[0116] When the device moves, the soil covering plate 73 is used to cover the sesbania seeds. The rotating shaft 22 rotates to drive the crushing roller 64 and the crushing knife group 65 to rotate by the first pulley 66, the belt 68 and the second pulley 67 to crush the wheat straw. The crushed wheat straw is discharged through the discharge box 63 to the top of the sesbania seeds covered with soil. The wheat straw covers the sesbania seeds to reduce the evaporation of soil moisture and form a physical barrier on the soil surface.

[0117] The driving shaft 86 rotates, and in cooperation with the first bevel gear 84 and the second bevel gear 87, drives the fertilizer spreading disc 82 and the fertilizer spreading knife group 83 to rotate, thereby spreading the fertilizer on the surface of the saline-alkali soil to fertilize the saline-alkali soil;

[0118] S3: Sesbania sesbania pressed green;

[0119] The drive shaft 86 rotates, and in cooperation with the third bevel gear 94 and the fourth bevel gear 95, the rotating rod 92 and the cutting blade assembly 93 are driven to rotate, so that the cutting blade assembly 93 can cut the sesbania from the bottom end;

[0120] The blades on the surface of the trenching knife group 23 are removed and replaced with cutting blades, and the belt 68 is removed. The cutting blades are driven to rotate by the rotating shaft 22 and the cutter disc through the rotation of the drive motor 25, thereby dividing the cut sesbania into small segments;

[0121] The covering mechanism 7 is disassembled, and then the pressing roller is installed on the two walking wheels 12 using a connecting sleeve on the opposite side of the two rotating seats 11. The movement of the device drives the pressing roller to press the field sesbania cut into small sections, thereby improving the soil structure of the saline-alkali land and facilitating the subsequent planting of sunflowers.
