[0002] In the field of seed drills, the intercropping mode of sorghum and peanuts has gradually attracted widespread attention because it can make full use of land resources and improve economic benefits. Traditional sorghum and peanut intercropping sowing and fertilization operations mostly rely on manual labor or simple agricultural machinery, which has many disadvantages. Manual sowing and fertilization are extremely inefficient, consuming a lot of manpower costs, and it is difficult to ensure the uniformity of sowing and fertilization, which can easily lead to uneven crop growth and affect the final yield. Even if some simple machines are used, they often have a single function, such as only having simple furrowing and sowing functions, and cannot take into account the precise and orderly placement of sorghum and peanut seeds at the same time, nor can they be used in Efficient fertilization is achieved simultaneously during sowing, and there is a lack of cleaning of seeds and effective control of the feeding process. In addition, during the seed feeding and fertilizer application process, the lack of reasonable buffering and anti-blocking design often causes seeds to be blocked and accumulated at the feeding port, and the fertilizer is unevenly distributed.

[0019] See also Figures 1 to 11 As shown, an embodiment of the present application provides a sorghum and peanut intercropping seeding and fertilization machine, including an equipment traction frame 10, and also includes: a double-slot seed bin 20, an ordered unloading assembly 30, a pneumatic cleaning assembly 40, a plurality of front furrowing sowing assemblies 50, a power device 60, a fertilizer storage bin 70 and a plurality of rear furrowing sowing assemblies 80.

[0020] Specifically, the double-slot seed bin 20 is fixedly mounted on the equipment traction frame 10, and the double-slot seed bin 20 is used to place sorghum and peanut seeds. A plurality of seed discharge ports are arranged at the bottom of each slot in the double-slot seed bin 20; the fertilizer storage bin 70 is fixedly mounted next to the double-slot seed bin 20, and a plurality of fertilizer discharge ports are arranged at the bottom of the fertilizer storage bin 70; the orderly discharge assembly 30 is arranged on the bottom walls of the two slots of the double-slot seed bin 20, and on the bottom wall of the fertilizer storage bin 70; the gas output end of the pneumatic cleaning assembly 40 is located at each slot of the double-slot seed bin 20 The bottom of the inner cavity is used to clean the seeds before sowing; the power device 60 is in contact with the ground, and the power output end of the power device 60 is connected to the orderly unloading assembly 30 and the pneumatic cleaning assembly 40; a plurality of front furrowing sowing assemblies 50 are equidistantly arranged on the front side of the bottom end of the equipment traction frame 10; each front furrowing sowing assembly 50 is connected to the inner cavity of the double-slot seed bin 20 located on the front side; a plurality of rear furrowing sowing assemblies 80 are equidistantly arranged on the rear side of the bottom end of the equipment traction frame 10; each rear furrowing sowing assembly 80 is connected to the inner cavity of the double-slot seed bin 20 located on the rear side; The front furrowing and sowing assembly 50 and / or the rear furrowing and sowing assembly 80 are also connected to the fertilizer storage bin 70 , and the gas delivery channel of the pneumatic cleaning assembly 40 passes through the front furrowing and sowing assembly 50 and / or the rear furrowing and sowing assembly 80 .

[0021] It should be noted that in the sorghum and peanut intercropping sowing and fertilizing machine provided by the present application, the equipment traction frame 10 serves as the support and traction structure of the entire machine, and can be connected to an external traction device, such as a tractor, so as to operate in the field. The double-slot seed bin 20 is fixedly mounted on the equipment traction frame 10, for example, specifically used to place sorghum and peanut seeds, and a plurality of seed discharge ports are arranged at the bottom of each slot, so that seeds can be discharged evenly from different positions to ensure the uniformity of sowing. The fertilizer storage bin 70 is fixedly mounted adjacent to the double-slot seed bin 20, and a plurality of fertilizer discharge ports are also arranged at its bottom end, so as to perform fertilization operations while sowing. The orderly discharge assembly 30 is respectively arranged on the bottom walls of the two slots of the double-slot seed bin 20 and on the bottom wall of the fertilizer storage bin 70, so that the timing of discharging seeds and fertilizers can be orderly controlled at the same time through the orderly discharge assembly 30, so as to ensure the timing and amount of discharging, and avoid blockage or uneven discharging. The gas output end of the pneumatic cleaning component 40 is located at the bottom of the inner cavity of each slot of the double-slot seed bin 20. During the sowing process, the pneumatic cleaning component 40 can transport clean gas into the seed bin to clean the seeds and remove impurities and dust on the surface of the seeds, thereby improving the germination rate and sowing quality of the seeds. At the same time, through the power of the gas, it can further prevent the problem of seeds being blocked at the seed feeding port. The power device 60 is in contact with the ground, and its power output end is connected to the orderly feeding component 30 and the pneumatic cleaning component 40. When the machine travels in the field, the power device 60 generates power through friction with the ground, and transmits the power to the orderly feeding component 30 and the pneumatic cleaning component 40 to ensure the feeding of seeds and fertilizers and the cleaning work. Each front furrowing sowing component 50 is connected to the inner cavity of the double-slot seed bin 20 located on the front side. During the movement of the machine, the front furrowing sowing component 50 first opens a sowing furrow on the land, and then sows the seeds in the front slot of the double-slot seed bin 20 into the furrow. Similarly, a plurality of rear furrowing sowing assemblies 80 are equidistantly arranged at the rear side of the bottom end of the equipment traction frame 10, and each rear furrowing sowing assembly 80 is connected to the inner cavity of the double-slot seed bin 20 located at the rear side, and is responsible for sowing the seeds in the rear slot into the opened furrow. In addition, the front furrowing sowing assembly 50 and / or the rear furrowing sowing assembly 80 are also connected to the fertilizer storage bin 70, and the fertilizer in the fertilizer storage bin 70 can be applied to the sowing furrow while sowing, but the fertilizer does not fall at the same time as the seeds to prevent the burning of the seedlings. In addition, the gas delivery channel of the pneumatic cleaning assembly 40 passes through the front furrowing sowing assembly 50 and / or the rear furrowing sowing assembly 80, so that in the process of seeds and fertilizers falling, gas can also be used to buffer the seeds and fertilizers in the falling process, so as to prevent the seeds and fertilizers from falling away from the preset sowing point or even popping out of the sowing furrow after falling quickly, thereby realizing a gas buffer structure to ensure the continuous and stable sowing and fertilization work.

[0022] like Figure 3and Fig. 9 As shown, in some examples, further, the inner cavity of the fertilizer storage bin 70 and the double-slot seed bin 20 is also provided with: a disturbance rod 21 and a jet cleaning tube 22, the disturbance rod 21 is in a spiral filament shape as a whole, the disturbance rod 21 is located at the fertilizer discharge port and multiple seed discharge ports in the two slots, and the end of the disturbance rod 21 is connected to the output end of the power device 60; the jet cleaning tube 22 is fixedly fitted on the inner bottom of at least one slot, the air inlet end of the jet cleaning tube 22 is connected to the output end of the pneumatic cleaning assembly 40, the jet cleaning tube 22 is located at the bottom of the slot, and jets air from the bottom of the slot to the slot, and blows out impurities and dust on the surface of the seeds in conjunction with the continuous disturbance action of the seeds.

[0023] Specifically, the end of the disturbance rod 21 is connected to the output end of the power device 60. During operation, after the power device 60 is started, the disturbance rod 21 will be driven to rotate. For the fertilizer storage bin 70, since the fertilizer may clump or accumulate due to its own characteristics, the spiral filament-shaped disturbance rod 21 will stir and disturb the fertilizer during rotation to prevent the fertilizer from caking in the storage bin and ensure that the fertilizer discharge port can discharge smoothly. For the double-slot seed bin 20, the rotation of the disturbance rod 21 can also prevent the seeds from accumulating in the slot or blocking the seed discharge port, so that the seeds can flow downward more evenly, ensuring the stability and uniformity of the seed discharge.

[0024] When the pneumatic cleaning component 40 is working, a cleaning gas with a certain pressure will be generated, and the gas will enter the jet cleaning pipe 22 through the air inlet end. The cleaning gas is ejected from the jet cleaning pipe 22 to clean the seeds in the seed bin. This cleaning method helps to remove dust, impurities and possible fine particles on the surface of the seeds, improve the purity of the seeds, and prepare for subsequent sowing. The setting of the jet cleaning pipe 22 can also cooperate with the disturbance rod 21 to achieve a further disturbance effect, ensure the smoothness of seed feeding, and effectively clean the seeds before feeding, which helps to improve the working efficiency and sowing quality of the sorghum and peanut intercropping sowing and fertilization machine, and reduce sowing problems caused by blockage of seeds and fertilizers or unclean seeds.

[0025] like Figure 4 , Figure 7 , Fig.10 and Fig.11 As shown, in some examples, further, the ordered feeding assembly 30 includes a horizontal axis 31, and also includes: a plurality of snap-fit ​​seats 32 and a feeding roller 33, the plurality of snap-fit ​​seats 32 are respectively fixedly snapped on all the seed feeding ports and the fertilizer feeding ports; the feeding roller 33 is arranged in the inner cavity of the snap-fit ​​seat 32, the feeding roller 33 is coaxially arranged with the horizontal axis 31, and each feeding roller 33 is provided with a feeding trough opened along the circumferential direction.

[0026] The main function of the multiple snap-fit ​​seats 32 is to connect the discharge port and the feed roller 33 together to form a relatively closed discharge channel; to ensure that seeds and fertilizers can only be discharged through the feed roller 33, to ensure the sealing and controllability of the discharge process; specifically, the feed roller 33 is arranged in the inner cavity of the snap-fit ​​seat 32 and is coaxially arranged with the horizontal shaft 31; when the power device 60 drives the horizontal shaft 31 to rotate, the feed roller 33 will also rotate accordingly; a discharge groove is provided on the feed roller 33 in the circumferential direction; during operation, as the feed roller 33 rotates, the discharge groove below the seed discharge port can be periodically aligned with the seed discharge port by rotating, and the discharge groove below the fertilizer discharge port can be periodically aligned with the fertilizer discharge port by rotating; when the feed roller 3 When the feeding trough of the feeding roller 33 rotates to a position aligned with the feeding port, the seeds or fertilizers will enter the feeding trough; then, as the feeding roller 33 continues to rotate, the feeding trough filled with seeds or fertilizers will carry them to a predetermined position, and when it rotates to a certain angle, due to gravity or other mechanisms that assist feeding (such as vibration, etc.), the seeds or fertilizers will fall from the feeding trough, thereby realizing the feeding operation; since the feeding trough on the feeding roller 33 is opened along the circumferential direction, and the rotation of the feeding roller 33 is driven by the horizontal shaft 31, the feeding operation is carried out in an orderly manner; during each rotation of the feeding roller 33, a certain amount of seeds or fertilizers will be transported out according to the capacity of the feeding trough, avoiding uneven distribution caused by a large amount of seeds or fertilizers falling at the same time.

[0027] like Figures 1 to 4 As shown, in some examples, further, the power device 60 includes: two connecting arms 61, a first transmission wheel 62, a driving wheel 63, a second transmission wheel 64, three third transmission wheels 65 and three fourth transmission wheels 66, the two connecting arms 61 are fixedly arranged on the side walls of the double-slot seed bin 20; the driving wheel 63 is rotatably arranged on the end of the lower end of the connecting arm 61, and the driving wheel 63 is used to contact the ground; the first transmission wheel 62 is fixedly sleeved on the shaft body in the middle of the driving wheel 63; multiple second transmission wheels 64 are fixedly sleeved on the ends of the horizontal shaft 31; the three third transmission wheels 65 are respectively fixedly sleeved on the ends of the three horizontal shafts 31; the three fourth transmission wheels 66 are respectively fixedly connected to the ends of the disturbance rod 21; wherein, the three third transmission wheels 65 are transmission connected and rotate synchronously, the three fourth transmission wheels 66 are transmission connected and rotate synchronously, and the first transmission wheel 62 is transmission connected to the second transmission wheel 64.

[0028] In this example, when the seeding and fertilizing machine moves in the field, the driving wheel 63 rolls in contact with the ground, and the rotation of the driving wheel 63 drives the first transmission wheel 62 mounted on its shaft to rotate; the transmission connection between the first transmission wheel 62 and the second transmission wheel 64 transmits power to the second transmission wheel 64, thereby driving the horizontal shaft 31 to rotate, and the rotation of the horizontal shaft 31 drives the feed roller 33 in the orderly unloading component 30 to rotate, thereby realizing orderly unloading; at the same time, the transmission connection between the three third transmission wheels 65 ensures the synchronous rotation of multiple horizontal shafts 31, ensuring that the unloading actions of the orderly unloading components 30 at different positions are consistent; and the power transmitted by the first transmission wheel 62 is also transmitted to the three fourth transmission wheels 66 through the transmission system, so that the disturbance rod 21 rotates, stirs and disturbs the materials in the fertilizer storage bin 70 and the double-slot seed bin 20, and ensures smooth unloading of the materials.

[0029] like Figure 5 As shown, in some examples, further, the pneumatic cleaning assembly 40 includes: an air cylinder 41, a reciprocating screw rod 42, a piston 43, two air intake check valves 44, two air supply pipes 45 and two air exhaust check valves 46; the air cylinder 41 is fixedly arranged between two driving wheels 63, and the air cylinder 41 is in a hollow state; the reciprocating screw rod 42 is rotatably arranged in the middle of the inner cavity of the air cylinder 41, and the two ends of the reciprocating screw rod 42 are also fixedly connected to the middle of the driving wheel 63; the piston 43 can move along the length direction of the air cylinder 41 is arranged in the inner cavity of the air cylinder 41, and is movably sleeved on the outer wall of the reciprocating screw 42 through a screw nut; two air intake check valves 44 are fixedly mounted on the two end portions of the air cylinder 41; two air supply pipes 45 are respectively fixedly connected to the two end portions of the air cylinder 41, and the other ends of the two air supply pipes 45 pass through the front furrowing sowing assembly 50 and / or the rear furrowing sowing assembly 80, and are fixedly connected to the air intake end of the jet cleaning pipe 22; two exhaust check valves 46 are fixed on the connecting end of the air supply pipe 45 and the air cylinder 41.

[0030] In this example, the air cylinder 41 is fixedly arranged between two driving wheels 63, and the air cylinder 41 is in a hollow state, providing space for the flow and compression of gas. The reciprocating screw 42 can be rotatably arranged in the middle position of the inner cavity of the air cylinder 41, and when the driving wheel 63 rotates, it will drive the reciprocating screw 42 to rotate. The piston 43 is movably sleeved on the outer wall of the reciprocating screw 42 through the screw nut. When the driving wheel 63 drives the reciprocating screw 42 to rotate, the piston 43 will reciprocate in the air cylinder 41. Two air intake check valves 44 are fixedly installed on the two ends of the air cylinder 41. Their function is to control the gas to enter the air cylinder 41 only from the outside. When the piston 43 moves to one end, the air intake check valve 44 on the back side of the moving direction opens, and the exhaust check valve 46 on the front side of the moving direction exhausts to the air supply pipe 45, and finally the gas generated in the air cylinder 41 is transported to the position of the seed falling buffer and the position where the seed feeding port is easily blocked.

[0031] When the seeding and fertilizing machine is working, the driving wheel 63 drives the reciprocating screw rod 42 to rotate, thereby causing the piston 43 to reciprocate in the air cylinder 41, thereby realizing the suction and discharge operations of the gas in the air cylinder 41. Through the cooperation of the air intake check valve 44 and the exhaust check valve 46 arranged on both sides of the air cylinder 41, the gas can be continuously sucked in, compressed, and then continuously transported to the jet cleaning pipe 22 through the air supply pipe 45, so as to clean the seeds in the double-slot seed bin 20, and achieve an anti-blocking effect. It can also buffer the falling seeds and fertilizers in the front furrowing sowing component 50 or the rear furrowing sowing component 80, and prevent the seeds and fertilizers from touching the inclined surface in the soil at a higher falling speed and popping out of the sowing furrow, thereby effectively improving the sowing survival rate.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some examples, further, the front furrowing sowing assembly 50 and the rear furrowing sowing assembly 80 both include: a connecting frame 81, two groups of seed feeding pipes 82 and a furrow opener 85, the top end of each group of seed feeding pipes 82 in the two groups of seed feeding pipes 82 are respectively connected to the ordered feeding assembly 30 on the double-slot seed bin 20; the connecting frame 81 is fixedly connected between the seed feeding pipe 82 and the equipment traction frame 10; the furrow opener 85 is fixedly connected to the bottom end of the seed feeding pipe 82, and the furrow opener 85 includes two parts of inclined plates, and the bottom end of the seed feeding pipe 82 extends to the back side of one of the inclined plates.

[0033] In this example, the front furrowing sowing assembly 50 and the rear furrowing sowing assembly 80 include the same structure that provides a seed dropping function, wherein a connecting frame 81 is fixedly connected between a seed feeding pipe 82 and an equipment traction frame 10, to ensure that the seed feeding pipe 82 is stable and will not shake or shift at will during the movement of the machine; the top end of each group of seed feeding pipes 82 is respectively connected to an ordered feeding assembly 30 on a double-slot seed bin 20, and the ordered feeding assembly 30 is responsible for conveying seeds according to a predetermined rhythm and quantity, and the seeds flow to the back side of the furrow opener 85 through the feeding pipe; since sorghum and peanut seeds are placed in different slots of the double-slot seed bin 20, respectively, the corresponding two groups of seed feeding pipes 82 can respectively Sorghum seeds and peanut seeds are accurately transported to the corresponding sowing furrows, ensuring that the seeds of the two crops can be planted as planned during intercropping, which is beneficial to the later field management and crop growth; the furrow opener 85 is fixedly connected to the bottom end of the seed feeding pipe 82; the two parts of the inclined plates form a "V"-shaped structure, and the bottom end of the seed feeding pipe 82 extends to the back side of one of the inclined plates; when the seeding and fertilizing machine moves forward, the furrow opener 85 cuts into the soil, and the inclined plates push the soil to both sides to form a sowing furrow; at this time, the seed feeding pipe 82 located on the back side of the inclined plate sows the seeds into the opened furrow, and the seeds can slide to the bottom of the furrow along the inclined plate, completing the seed falling process.

[0034] like Figure 7 and Figure 8 As shown, in some examples, further, at least one of the front furrowing sowing assembly 50 and the rear furrowing sowing assembly 80 is also provided with: a fertilizer discharge pipe 83 and a buffer portion 84, the fertilizer discharge pipe 83 is connected to the equipment traction frame 10 through the connecting frame 81, the length of the fertilizer discharge pipe 83 is less than the length of the seed discharge pipe 82, the fertilizer discharge pipe 83 is located on another inclined plate opposite to the seed discharge pipe 82, and the top of the fertilizer discharge pipe 83 is connected to the fertilizer discharge port; the buffer portion 84 is fixedly sleeved between the fertilizer discharge pipe 83 and the seed discharge pipe 82; the buffer portion 84 is used to reduce the falling speed of seeds and fertilizers.

[0035] In this example, it should be noted that the fertilizer feed pipe 83 is connected to the equipment traction frame 10 through the connecting frame 81, and its length is less than the length of the seed feed pipe 82, in order to stagger the falling positions of the seeds and fertilizers. When the machine performs sowing and fertilizing operations, the fertilizer enters the fertilizer feed pipe 83 from the fertilizer storage bin 70 through the fertilizer feed port. Since the fertilizer feed pipe 83 and the seed feed pipe 82 are located at different inclined plate positions of the furrow opener 85 and have different lengths, it can be ensured that the fertilizer and seeds fall into the planting furrow at different times and will not fall to the same position, thereby avoiding the direct mixing of seeds and fertilizers and the occurrence of seedling burns, and there is no need to use a more complex fertilizer application structure.

[0036] The buffer part 84 is fixedly sleeved between the fertilizer feeding pipe 83 and the seed feeding pipe 82, and its main function is to reduce the falling speed of the seeds and fertilizers when they enter the sowing furrow. During the sowing and fertilization process, if the seeds and fertilizers fall too fast, the seeds and fertilizers may not be at the expected sowing point position, and may even pop out of the sowing furrow, thereby affecting the growth of crops. Therefore, the buffer part 84 can effectively control the falling speed of seeds and fertilizers through its own structure and function.

[0037] like Figure 8 As shown, in some examples, further, the buffer portion 84 includes: a connecting block 841, a snap-in groove 842, a narrowing section 843 and a plurality of back-suction channels 844, the connecting block 841 is snap-connected between the fertilizer feed pipe 83 and the seed feed pipe 82 through the snap-in grooves 842 opened at both ends, an air flow channel is arranged in the inner cavity of the connecting block 841, the air flow channel is connected to the air supply pipe 45, a narrowing section 843 is arranged in the middle of the air flow channel, and the diameter of the narrowing section 843 is smaller than the diameter of other air flow channels; a plurality of back-suction channels 844 are equidistantly opened along the length direction of the fertilizer feed pipe 83 and the seed feed pipe 82, and penetrate the connecting block 841, the seed feed pipe 82 and the fertilizer feed pipe 83.

[0038] Specifically, an airflow channel is provided in the inner cavity of the connecting block 841, and the airflow channel is connected to the air supply pipe 45. When the pneumatic cleaning component 40 generates airflow, the airflow flows into the airflow channel of the connecting block 841 along the air supply pipe 45. A narrowing section 843 is provided in the middle of the airflow channel, and its diameter is smaller than that of other airflow channels, and the Venturi effect is applied here. According to the principle of the Venturi effect, when gas or liquid flows through the narrowed part of the pipeline, the flow rate will increase and the pressure will decrease, thereby forming a low-pressure area around the narrowing section 843.

[0039] A plurality of back-suction channels 844 penetrate the connection block 841, the seed feeding pipe 82 and the fertilizer feeding pipe 83. When the narrowed section 843 forms a low-pressure area, due to the pressure difference, the gas in the fertilizer feeding pipe 83 and the seed feeding pipe 82 will flow to the low-pressure area through the back-suction channel 844, thereby generating a back-suction effect. The back-suction effect can effectively slow down the falling speed of seeds and fertilizers, as if applying an upward pulling force to them, to prevent them from falling rapidly due to gravity, resulting in excessive differences in their distribution positions in the soil.

[0040] For example, in actual sowing and fertilizing operations, seeds and fertilizers would originally rush toward the soil quickly under the action of gravity, but due to the action of the buffer part 84, the airflow produces a Venturi effect in the connecting block 841, driving the back-suction channel 844 to function, allowing the seeds and fertilizers to enter the soil at a slower and more uniform speed, ensuring that the seeds and fertilizers are distributed in the soil at the expected fixed points, providing a better growth environment for the growth of sorghum and peanuts.

[0041] like Figure 8 As described, in some examples, further, the connecting block 841 is also provided with: an adjustment plate 845 capable of moving linearly along the arrangement direction of the multiple back-suction channels 844, and each adjustment plate 845 is also provided with an adjustment hole 846 capable of corresponding to the positions of the multiple back-suction channels 844, and the adjustment hole 846 can be staggered with the back-suction channel 844 for adjusting the size and suction force of the back-suction channel 844.

[0042] In this example, based on the air flow channel in the connecting block 841, the Venturi effect is utilized to slow down the falling speed of seeds and fertilizers through the back-suction channel 844; on this basis, the adjusting piece 845 can move linearly along the arrangement direction of the multiple back-suction channels 844, so that the operator can make dynamic adjustments according to the actual needs of sowing and fertilization; the adjusting piece 845 can be realized by the pulling action of an operating rod (not shown in the figure) that is additionally provided and can extend to the outside of the connecting block 841. If the position of the adjusting piece 845 is to be locked, any locking structure can be used, such as providing a threaded structure on the operating rod to cooperate with a nut, or using a magnetic structure to adsorb and fix the operating rod, or providing a latch structure with different gears on the outer wall of the connecting block 841, and structures such as friction pressure can also be used to resist the locking and release of the operating rod.

[0043] Specifically, each adjusting piece 845 is provided with an adjusting hole 846 corresponding to the position of the back-suction channel 844. Due to the different seed sizes of different sorghum and peanut varieties, the coarseness of the fertilizer particles is also different. When facing larger particles of seeds or fertilizers, the operator can move the adjusting piece 845 to displace the adjusting hole 846 and the back-suction channel 844. In this way, the actual ventilation cross-sectional area of ​​the back-suction channel 844 is reduced, and the suction force is also changed accordingly. On the one hand, it avoids the seeds or fertilizer particles being accidentally sucked into the back-suction channel 844 due to excessive suction, causing the feed pipe to be blocked and affecting the sowing and fertilizing process. On the other hand, by precisely controlling the suction force, it can also ensure that the seeds and fertilizers still fall at a suitable, relatively slow and uniform speed, maintaining a precise distribution state in the soil.

[0044] like Figures 1 to 3As shown, in some examples, further, a naturally drooping soil covering plate 90 is further provided on the rear side of the equipment traction frame 10, and the width range of the soil covering plate 90 covers the sowing and fertilizing range of the front furrowing and sowing component 50 and the rear furrowing and sowing component 80; after sowing and fertilizing, the soil covering plate 90 can naturally cover the soil on both sides of the furrows opened by the furrowing and sowing component on the seeds and fertilizers in time, play a good role in covering the soil, effectively prevent the seeds and fertilizers from being exposed to the outside, and reduce the impact of external factors such as wind, sun, rain, etc. on the seeds and fertilizers. Because its width can cover the entire sowing and fertilization range, the integrity of the soil covering is guaranteed.

[0045] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
