[0002] Alfalfa is a perennial herbaceous plant of the genus Medicago in the Leguminosae family, commonly known as purple alfalfa and purple alfalfa, and is known as the "king of forage grass". It has a well-developed root system and a thick taproot that can penetrate 4 to 6 meters into the soil. The leaves are pinnate-trifoliate compound leaves with large stipules and an ovate-lanceolate shape. Alfalfa has strong adaptability to the growth environment and can grow under different climate and soil conditions. It is mainly used as high-quality feed in animal husbandry. With the development of scale and industrialization of alfalfa, in order to increase alfalfa yield and quality, it is necessary to use a fertilization device to fertilize alfalfa.

[0003] Announcement No.: CN117957956B discloses a portable fertilizing device and method for alfalfa. Through the setting of a soil-breaking mechanism, the soil is broken into pieces and scattered, so that the anti-blocking storage mechanism and the quantity-controlled spreading mechanism cooperate to evenly mix the spread fertilizer into the soil, thereby ensuring the subsequent alfalfa's absorption efficiency of soil fertilizer. In addition, by utilizing the setting of a soil-covering mechanism, the soil after the fertilizer is spread can be scraped, covered and mixed, thereby cooperating to ensure the fertilization efficiency of alfalfa planting.

A driving motor 28 for driving the driving shaft 25 to rotate is arranged on the left side of the mounting frame 1, and a mounting seat 29 is arranged at the bottom of the driving motor 28;

[0051] Please combine Figure 3 and Figure 4: Start the drive motor 28, and the drive motor 28 rotates to drive the drive shaft 25 to rotate, and the drive shaft 25 rotates to drive the two second bevel gears 26 to rotate, and the two second bevel gears 26 rotate to drive the two first bevel gears 24 to rotate, and the two first bevel gears 24 then drive the two fertilizer spreading discs 22 to rotate toward the separated side, when the fertilizer falls on the top of the fertilizer spreading disc 22, the two fertilizer spreading discs 22 rotate in cooperation with the arc-shaped fertilizer spreading plate 23, so that the fertilizer is spread to the alfalfa planting field;

[0052] The reciprocating swing mechanism 3 includes a rotating shaft 31 rotatably connected to the inner side of the right side of the mounting frame 1, and the right side of the driving shaft 25 and the surface of the rotating shaft 31 are both key-connected with a driving gear 32, and the two driving gears 32 are meshed with each other. A first rotating disk 33 is fixedly arranged on the surface of the rotating shaft 31 and located on the right side of the driving gear 32, and a second rotating disk 34 is rotatably connected to the surface of the rotating shaft 31 and located on the right side of the first rotating disk 33, and an adjusting bolt 3 is arranged on the inner sides of the first rotating disk 33 and the second rotating disk 34. 5. A swing bracket 36 is rotatably connected to the inner side of the right side of the mounting frame 1. A tension spring 37 is arranged on the inner side of the swing bracket 36. The bottom end of the tension spring 37 is fixedly connected to the surface of the mounting frame 1. A rotating ring 38 is rotatably connected to the surface of the top of the swing bracket 36. A swing rod 39 is fixedly arranged on the left side of the bottom of the swing bracket 36. The left end of the swing rod 39 is rotatably connected to the inner side of the mounting frame 1. A slapping plate 310 is fixedly arranged on the surface of the swing rod 39. A protective frame 311 is arranged on the top of the inner side of the right side of the mounting frame 1.

[0053] Please combine Figures 5 to 7 When the driving shaft 25 rotates, the front driving gear 32 is driven to rotate, and the front driving gear 32 is driven to rotate, and the rear driving gear 32 is driven to rotate by the rotation of the rear driving gear 32, and the rotating shaft 31 is driven to rotate, and the rotating shaft 31 is driven to rotate, thereby driving the first rotating disk 33 and the second rotating disk 34 to rotate, and the first rotating disk 33 and the second rotating disk 34 are rotated, and the swing bracket 36 is reciprocated by the action of the tension spring 37, and the reciprocating swing of the swing bracket 36 drives the swing rod 39 and the slapping plate 310 to reciprocate. When fertilizing alfalfa in the seedling stage and the growth stage, the swinging action of the slapping plate 310 cooperates with the movement of the device, so that the alfalfa is tilted to a certain extent, and the swinging action of the slapping plate 310 is used to restore the alfalfa, and the swinging action of the slapping plate 310 is used to make the alfalfa shake, so that the fertilizer falling on the surface of the alfalfa during fertilization falls into the soil;

[0054] Further, the adjusting bolt 35 is loosened, and then the second rotating disk 34 is rotated to make the second rotating disk 34 and the first rotating disk 33 staggered at a larger distance, and then the second rotating disk 34 and the first rotating disk 33 are connected by the adjusting bolt 35. When the first rotating disk 33 and the second rotating disk 34 rotate, the overlapping portion of the protrusions of the two is small, so that the rotating ring 38 stays on the protruding portion for a longer time. Therefore, it is concluded that by adjusting the positions of the first rotating disk 33 and the second rotating disk 34 by using the adjusting bolt 35, the swing bracket 36 can be adjusted to drive the swing rod 39 and the flapping plate 310 to flap the alfalfa, and then the alfalfa can be adjusted according to different growth stages to avoid the alfalfa stems being damaged by excessive swing frequency;

[0055] Preferably, when fertilizing the soil before planting alfalfa, the two driving gears 32 are moved to the left to cancel the connection with the driving shaft 25 and the rotating shaft 31, and then when the fertilizer spreading disc 22 is driven to spread fertilizer by the driving shaft 25 using the second bevel gear 26 and the first bevel gear 24, the rotating shaft 31 will not drive the flapping plate 310 to swing through the first rotating disc 33, the second rotating disc 34 and the swing bracket 36.

[0056] A frame plate is provided inside the fertilizer hopper 21 for filtering block fertilizers. The number of the arc-shaped fertilizer spreading plates 23 on the top of the two fertilizer spreading plates 22 is 4. When the two second bevel gears 26 rotate, the two first bevel gears 24 are used to rotate the two fertilizer spreading plates 22 in the direction of separation.

[0057] The inner sides of the first rotating disk 33 and the second rotating disk 34 are both provided with arc-shaped through grooves, which are used in conjunction with the adjusting bolts 35. By loosening the adjusting bolts 35, the position of the second rotating disk 34 is adjusted so that the two arc-shaped through grooves completely overlap. When the rotating ring 38 is working, it fits with the surfaces of the first rotating disk 33 and the second rotating disk 34. The flapping plates 310 are made of rubber and there are three of them.

[0058] In this embodiment, unlike the existing device, when fertilizing alfalfa, the rotation of the drive shaft 25 drives the two fertilizer spreading discs 22 to rotate under the action of the first bevel gear 24 and the second bevel gear 26, so that the fertilizer is spread to the alfalfa planting field. Compared with the existing alfalfa fertilization device, the fertilization efficiency is greatly improved. During the rotation process, the drive shaft 25 will sequentially drive the two drive gears 32, the rotating shaft 31, the first rotating disc 33 and the second rotating disc 34 to rotate. Through the rotation of the first rotating disc 33 and the second rotating disc 34, under the action of the swing bracket 36 and the tension spring 37, the flapping plate 310 is driven to swing back and forth up and down. The downward swinging action of the beating plate 310 cooperates with the movement of the device, so that the alfalfa appears a certain inclination, and the upward swinging action of the beating plate 310 is used to restore the alfalfa. The downward and upward swinging actions of the beating plate 310 are used to make the alfalfa shake, so that the fertilizer falling on the surface of the alfalfa during fertilization falls into the soil. The positions of the first rotating disk 33 and the second rotating disk 34 are adjusted by adjusting the bolt 35, and the frequency of the beating of the alfalfa by the beating plate 310 driven by the swing bracket 36 can be adjusted, so as to facilitate the adjustment according to the different growth stages of the alfalfa, effectively improve the adaptability of the device, and can avoid damage to the alfalfa during fertilization, and will not affect the normal growth of the alfalfa.

[0079] In this embodiment, by rotating the adjustment plate 62, the size of the fertilizer outlet at the bottom of the fertilizer hopper 21 can be adjusted, thereby adjusting the fertilizer discharge speed. When the device moves, it will drive the threaded rod 74 and the scraper plate 75 to move. By setting the threaded rod 74, the height position of the scraper plate 75 can be adjusted. The movement of the scraper plate 75 can be used to scrape the weeds in the alfalfa row. By adjusting the height of the two sliders 9 and the connecting frame 11, the connection height between the device and the agricultural machinery can be adjusted, so that the device can easily adapt to the height of alfalfa at different growth stages.

[0080] Please refer to Figures 1 to 14 The working principle of the alfalfa planting and fertilizing device provided by the present invention is as follows:

[0081] Step S1, firstly, according to the growth stage of alfalfa, the height positions of the two sliders 9 and the connecting frame 11 are adjusted by the screw rod 10. When the alfalfa is in the seedling stage, the two sliders 9 and the connecting frame 11 are adjusted upward by the screw rod 10. When the alfalfa is in the growth stage, the two sliders 9 and the connecting frame 11 are adjusted downward by the screw rod 10. After adjustment, the connecting frame 11 is connected to the front end of the agricultural machine, and the agricultural machine driving device is used to move;

[0082] After adjusting the use height of the device, according to the spacing between rows of alfalfa, the positions of the mounting bracket 72, the threaded rod 74 and the grass scraper 75 are adjusted by the locking bolts 73 to adapt to the spacing between rows when alfalfa is planted. Then, the heights of the threaded rod 74 and the grass scraper 75 are adjusted by the nuts provided on the surface of the threaded rod 74. When the agricultural machine drives the device forward, the grass scraper 75 can be used to remove the weeds between the alfalfa rows to avoid weeds competing for nutrients after fertilizing the alfalfa.

[0083] Step S2, when it is necessary to fertilize alfalfa in the seedling stage and the growth stage, loosen the adjusting bolt 35, then rotate the second rotating disk 34, and then adjust the overlapping position between the second rotating disk 34 and the raised portion of the first rotating disk 33. When fertilizing alfalfa in the seedling stage, the overlapping position of the raised portion of the second rotating disk 34 and the first rotating disk 33 is increased, thereby reducing the frequency of the swing bracket 36 driving the flapping plate 310 to flap the alfalfa. When fertilizing alfalfa in the growth stage, the overlapping position of the raised portion of the second rotating disk 34 and the first rotating disk 33 is reduced, thereby increasing the frequency of the swing bracket 36 driving the flapping plate 310 to flap the alfalfa. The specific adjustment amplitude is based on the premise that the flapping plate 310 will not cause damage to the alfalfa stems when flapping the alfalfa.

[0084] When fertilizing the soil before planting alfalfa, the two driving gears 32 are moved to the left to cancel the connection relationship with the driving shaft 25 and the rotating shaft 31, and then the driving shaft 25 drives the fertilizer spreading disc 22 to spread fertilizer using the second bevel gear 26 and the first bevel gear 24, and the rotating shaft 31 does not drive the flapping plate 310 to swing through the first rotating disc 33, the second rotating disc 34 and the swing bracket 36;

[0085] Step S3, pour the fertilizer used for alfalfa fertilization into the fertilizer hopper 21, filter the fertilizer using the frame plate, and then crush the larger fertilizer particles on the frame plate to prevent the larger fertilizer blocks from blocking the discharge port during the fertilization process. When the device is moved to the work site, loosen the adjustment bolt 63 and rotate the adjustment plate 62 to adjust the size of the discharge port at the bottom of the fertilizer hopper 21, thereby adjusting the discharge speed of the fertilizer;

[0086] The agricultural machine drives the device to move forward, and the drive motor 28 is started. The drive motor 28 rotates to drive the drive shaft 25 to rotate. The drive shaft 25 rotates to drive the two second bevel gears 26 to rotate. The two second bevel gears 26 rotate to drive the two first bevel gears 24 to rotate. The two first bevel gears 24 then drive the two fertilizer spreading discs 22 to rotate toward the separated side. When the fertilizer falls on the top of the fertilizer spreading disc 22, the fertilizer is spread to the alfalfa planting field through the rotation of the two fertilizer spreading discs 22 in cooperation with the arc-shaped fertilizer spreading plate 23.

[0087] Step S4, when the driving shaft 25 rotates, it will drive the front driving gear 32 to rotate, and the front driving gear 32 rotates to drive the rear driving gear 32 to rotate, and the rear driving gear 32 rotates to drive the rotating shaft 31 to rotate, and the rotating shaft 31 rotates to drive the first rotating disk 33 and the second rotating disk 34 to rotate, and the first rotating disk 33 and the second rotating disk 34 rotate, and the swing bracket 36 is reciprocated by the action of the tension spring 37, and the reciprocating swing of the swing bracket 36 drives the swing rod 39 and the slapping plate 310 to reciprocate. When fertilizing alfalfa in the seedling stage and the growth stage, the swinging action of the slapping plate 310 cooperates with the movement of the device, so that the alfalfa is tilted to a certain extent, and the upward swing action of the slapping plate 310 cancels the thrust on the alfalfa, and the position of the alfalfa stem is actively restored. The swinging action of the slapping plate 310 is used to make the alfalfa shake, so that the fertilizer falling on the surface of the alfalfa during fertilization falls into the soil;

[0088] Step S5, using a pipeline to connect the water pump 52 with the water tank 51 and the spray pipe 53 respectively, so that the foliar fertilizer in the water tank 51 can be sprayed onto the alfalfa leaves through the spray pipe 53 and the nozzle 54 through the water pump 52;

[0089] When the fertilizing mechanism 2 fertilizes alfalfa, the continuous rotation of the driving shaft 25 will drive the two active gears 44 to rotate continuously, so that the two special-shaped tooth plates 43 slide back and forth on the inner side of the sliding seat 42, and the two special-shaped tooth plates 43 slide back and forth, thereby driving the two passive gears 45 to rotate back and forth, and the reciprocating rotation of the two passive gears 45 drives the spraying pipe 53 and the nozzle 54 to swing back and forth, so that the nozzle 54 can spray foliar fertilizer on the alfalfa leaves at multiple angles.
