[0024] With the increase of national investment in the agricultural industry, agricultural mechanization has also ushered in new development opportunities. The manufacturing of mechanized agricultural and gardening machinery such as intelligent agricultural power machinery has brought many conveniences to agricultural production. Fertilization refers to applying fertilizer to the soil or spraying it on plants to provide the nutrients required by plants, increase crop yields, and thus improve economic benefits. In the prior art, fertilizers are stirred to make fertilizers evenly applied, but some grass usually grows in the soil. If the grass is not treated, it will cause the grass to absorb part of the fertilizer and take away the nutrition of crops. The grass grows better, but the crops do not absorb the predetermined nutrients, affecting the growth of crops.

[0025] When the weeding mechanism provided by the present invention is in use, first, the fertilizer is evenly poured into the mixing cylinder 3, and then the stirring mechanism is started. The agglomerated fertilizer is broken by the stirring mechanism to facilitate uniform fertilization. During the stirring process of the stirring mechanism, the worm 331 drives the coupling 371 to rotate, the coupling 371 drives the second runner 372 to rotate, the second runner 372 drives the belt 373, the first runner 223 and the third runner 375 to rotate, the first runner 223 drives the roller shaft to rotate, the roller shaft drives the crushing cutter roller 222 to rotate, and the grass is crushed by the crushing cutter roller 222. And through the adjustment of the lifting mechanism, it is convenient to adjust the height of the crushing cutter roller 222 according to the type of grass, which is convenient for crushing the grass roots and preventing the grass roots from growing rapidly under suitable conditions; since the height of the crushing cutter roller 222 needs to be adjusted by the lifting mechanism, it is necessary to adjust the tightness of the belt 373 to ensure the transmission of the belt 373. During the adjustment process, it is necessary to rotate the rotating block 379, the rotating block 379 drives the threaded rod 377 to rotate, the threaded rod 377 drives the moving frame 374 to move, and the moving frame 374 drives the third runner 375 to move until the belt 373 is adjusted to the appropriate tightness; the synchronous progress of crushing and weeding also brings convenience to the manufacture of mechanized agriculture and horticultural implements such as intelligent agricultural power machinery.

[0026] As Figure 1 , Figure 5 and Figure 6 As shown in

[0027] The stirring mechanism provided by the present invention is used to break the agglomerated fertilizer during use. By starting the second motor 333, the second motor 333 drives the worm 331 to rotate through the output shaft, the worm 331 drives the spiral teeth to rotate, the spiral teeth drive the worm wheel 332 to rotate, the worm wheel 332 drives the rotating rod 334 to rotate, the rotating rod 334 drives the stirring paddle 335 to rotate, and the agglomerated fertilizer is broken by the stirring paddle 335 to facilitate the uniform spreading of the fertilizer and realize the uniformity of fertilization; among them, both the worm wheel 332 and the spiral teeth are arranged inside the movable box 33 to prevent the fertilizer from corroding the worm wheel 332 and the spiral teeth, resulting in poor meshing.

[0028] As Figure 4 and Figure 6As shown, two partition plates 32 are fixedly connected to the inner wall of the mixing cylinder 3, and the partition plates 32 are respectively arranged between two rotating rods 334; three discharge hoppers 35 are fixedly connected and communicated at the bottom of the mixing cylinder 3, and the discharge hoppers 35 cooperate with the partition plates 32 respectively.

[0029] When in use, the partition plate 32 provided by the present invention divides the mixing area, controls the diversion of fertilizers, and ensures that each discharge hopper 35 evenly receives fertilizers. The partition plate 32 is located between the rotating rods 334, and uses the directional flow generated by stirring to guide the fertilizers to different discharge hoppers 35 to achieve regional fertilization.

[0030] As Figure 5 and Figure 6 As shown, filter plates 36 are fixedly connected to the tops of the discharge hoppers 35, rotating rods 34 are fixedly connected to the bottoms of the rotating rods 334, and limit posts 341 are fixedly connected to the ends of the rotating rods 34 away from the rotating rods 334; two cross bars 343 are fixedly connected to the inner walls of the discharge hoppers 35, and swing rods 342 are slidably connected to the two cross bars 343 on the same side. Limiting ports 344 are formed in the swing rods 342, and the limit posts 341 slide in the limiting ports 344.

[0031] When in use, the filter plate 36 provided by the present invention is used to filter the fertilizers in small lumps. The small lump particles are filtered through the filter plate 36. At the same time, during the rotation of the rotating rod 334, the rotating rod 34 is driven to rotate through the rotating rod 334, and the limit post 341 is driven to rotate through the rotating rod 34. During the rotation of the limit post 341, the swing rod 342 is driven to reciprocate by squeezing the limiting port 344. During the reciprocating movement of the swing rod 342, the two ends of the swing rod 342 slide on the cross bar 343 respectively. The cross bar 343 facilitates crushing the fertilizers in small lumps, and at the same time, through the reciprocating movement, it facilitates the feeding of fertilizers and prevents the fertilizers from blocking the filter plate 36.

[0032] As Figure 5 As shown, spiral blades 336 are fixedly connected to the bottom ends of the rotating rods 334; the spiral blades 336 are arranged between the rotating rod 34 and the stirring paddle 335.

[0033] When in use, the spiral blade 336 provided by the present invention is located between the rotating rod 34 and the stirring paddle 335, that is, in the area close to the bottom of the mixing cylinder 3. While stirring, it realizes the axial advancement of the materials, continuously pushes the fertilizers at the bottom of the mixing cylinder 3 towards the discharge port, and prevents the wet or agglomerated fertilizers from blocking the discharge hopper 35, especially suitable for scenarios of organic fertilizers with high viscosity or high humidity fertilizers.

[0034] As Figure 3 and Figure 7As shown, at one end of the lifting plate 2 away from the crushing cutter roller 222, two crushing rollers 232 are rotatably connected. On one side of each crushing roller 232, a harrow tooth 231 is fixedly connected. Both ends of the harrow tooth 231 are fixedly connected to the bottom of the lifting plate 2 through a fixing rod 23. At the top of each crushing roller 232, a circular gear 233 is provided, and the two circular gears 233 are meshed. At the top of one of the circular gears 233, a driving assembly is provided.

[0035] The harrow teeth 231 and the crushing rollers provided by the present invention are used for covering soil during use. During the fertilization process, the grass is crushed by the crushing cutter roller 222, and then the fertilization ditch is dug out by the plowshare 43. Then, fertilization can be carried out through the feeding hopper 35. Finally, when the harrow teeth 231 pass by, the harrow teeth 231 cover and backfill the soil plowed up by the plowshare 43. Among them, there are large soil blocks, which are not only inconvenient for backfilling but also easy to move forward with the vehicle body 1. Finally, a large amount of soil blocks accumulate at the bottom of the vehicle body 1 and the vehicle body 1 cannot move forward. By setting the crushing rollers 232, under the guidance of the harrow teeth 231, the soil blocks will finally move towards the middle. Then, by starting the driving assembly, the driving assembly drives the crushing rollers 232 to rotate, and the soil blocks are crushed by the crushing rollers 232 and finally used for covering and backfilling the soil to achieve the covering of the fertilizer and prevent the fertilizer from volatilizing due to sunlight irradiation, resulting in waste of the fertilizer.

[0036] As Figure 3 , Figure 6 and Figure 7 As shown, the driving assembly includes a connecting rod 234 fixedly connected to the top of the crushing roller 232. At the top of the connecting rod 234, a first sprocket 311 is fixedly connected. At the top of the mixing cylinder 3, a protective box 31 is provided. The top of the connecting rod 234 is rotatably connected to one end of the protective box 31. The top of the middle rotating rod 334 is rotatably connected to the other end of the protective box 31, and a second sprocket 235 is fixedly connected to the rotating rod 334. A chain 312 is sleeved between the first sprocket 311 and the second sprocket 235.

[0037] The driving assembly provided by the present invention is used to drive the crushing rollers 232 to crush the soil blocks during use. During the rotation of the rotating rod 334, the first sprocket 311 is driven to rotate by the rotating rod 334, the chain 312 is driven to rotate by the first sprocket 311, the second sprocket 235 is driven to rotate by the chain 312, the connecting rod 234 is driven to rotate by the second sprocket 235, the connected crushing rollers 232 and circular gears 233 are driven to rotate by the connecting rod 234, the other circular gear 233 is driven to rotate in the opposite direction by the circular gear 233, and the connected crushing roller 232 is driven to rotate by the other circular gear 233, so as to achieve the function of crushing the soil blocks; the synchronous crushing of the fertilizer and the soil blocks also brings convenience to the manufacture of mechanized agriculture and horticultural machinery such as intelligent agricultural power machinery.

[0038] As Figure 1 andFigure 3 As shown in the figure, the lifting mechanism includes two fixed plates 24 fixedly connected to the top of the vehicle body 1. A bidirectional ball screw 243 is rotatably connected between the two fixed plates 24 through bearings; two moving plates 241 are symmetrically threadedly connected to the upper part of the bidirectional ball screw 243. The bottom of each moving plate 241 is rotatably connected to a connecting plate 245 through a pin shaft, and the bottom of each connecting plate 245 is rotatably connected to a connecting block 246 through a pin shaft; a cross plate 247 is fixedly connected to the bottom of the lifting plate 2, and the connecting blocks 246 are fixedly connected to the cross plate 247; one end of the bidirectional ball screw 243 is provided with a first motor 244; two guide rods 242 are fixedly connected between the two fixed plates 24, and the moving plates 241 are all slidably connected to the two guide rods 242.

[0039] When the lifting mechanism provided by the present invention is in use, during crushing, according to the type of grass, it is necessary to adjust the height of the crushing cutter roller 222. By turning on the first motor 244, the output shaft of the first motor 244 drives the bidirectional ball screw 243 to rotate. The bidirectional ball screw 243 drives the moving plates 241 to move in opposite directions. One end of the connecting plate 245 is driven by the moving plate 241 to move in opposite directions. The other end of the connecting plate 245 drives the connecting block 246 to move up and down. The connecting block 246 drives the cross plate 247 to move up and down. The cross plate 247 drives the lifting plate 2 to move up and down, thereby realizing the function of adjusting the height of the lifting plate 2; during the movement of the moving plate 241, the moving plate 241 slides on the guide rod 242, and the guide rod 242 limits the movement of the moving plate 241 in the horizontal direction.

[0040] As Figure 3 shown in the figure, four corners of the bottom of the lifting plate 2 are fixedly connected with columns 21, and the columns 21 are all slidably connected to the vehicle body 1.

[0041] When the column 21 provided by the present invention is in use, during the movement of the lifting plate 2, the lifting plate 2 drives the column 21 to move, and the column 21 slides on the vehicle body 1, limiting the movement of the lifting plate 2 in the vertical direction and also facilitating stable movement when adjusting the height.

[0042] As Figure 2 and Figure 4 shown in the figure, three plowshares 43 are provided between the feeding hopper 35 and the rake teeth 231, and the plowshares 43 are respectively horizontally aligned with the feeding hopper 35; a rectangular plate 42 is fixedly connected to the top of the three plowshares 43; a hydraulic cylinder 4 is fixedly connected to the top of the vehicle body 1, and the output end of the hydraulic cylinder 4 is fixedly connected to the top of the rectangular plate 42. Two sliding rods 41 are symmetrically fixedly connected to the top of the rectangular plate 42, and the sliding rods 41 are respectively slidably connected to the vehicle body 1.

[0043] The plowshare 43 provided by the present invention is used for plowing and fertilizing trenches during use. When fertilizing, in order to solve the problem of adjusting the plowshare 43 according to the fertilizing depth, the hydraulic cylinder 4 is opened, the output end of the hydraulic cylinder 4 drives the rectangular plate 42 to move, and the rectangular plate 42 drives the plowshare 43 to move until the appropriate fertilizing depth is reached.

[0044] Working principle: When the weeding mechanism provided by the present invention is in use, first, the fertilizer is evenly poured into the mixing cylinder 3, and then the stirring mechanism is started. The agglomerated fertilizer is broken by the stirring mechanism to facilitate uniform fertilization. During the stirring process of the stirring mechanism, the worm 331 drives the coupling 371 to rotate, the coupling 371 drives the second runner 372 to rotate, the second runner 372 drives the belt 373, the first runner 223 and the third runner 375 to rotate, the first runner 223 drives the roller shaft to rotate, the roller shaft drives the crushing cutter roller 222 to rotate, and the crushing cutter roller 222 crushes the grass. And through the adjustment of the lifting mechanism, it is convenient to adjust the height of the crushing cutter roller 222 according to the type of grass, which is convenient for crushing the grass roots and preventing the grass roots from growing rapidly under suitable conditions; since the height of the crushing cutter roller 222 needs to be adjusted by the lifting mechanism, it is necessary to adjust the tightness of the belt 373 to ensure the transmission of the belt 373. During the adjustment process, it is necessary to rotate the rotating block 379, the rotating block 379 drives the threaded rod 377 to rotate, the threaded rod 377 drives the moving frame 374 to move, and the moving frame 374 drives the third runner 375 to move until the belt 373 is adjusted to the appropriate tightness; the synchronous progress of crushing and weeding also brings convenience to the manufacturing of mechanized agriculture and horticultural machinery such as intelligent agricultural power machinery.

[0045] When fertilizing, in order to solve the problem of adjusting the plowshare 43 according to the fertilizing depth, the hydraulic cylinder 4 is opened, the output end of the hydraulic cylinder 4 drives the rectangular plate 42 to move, and the rectangular plate 42 drives the plowshare 43 to move until the appropriate fertilizing depth is reached.

[0046] By turning on the second motor 333, the second motor 333 drives the worm 331 to rotate through the output shaft, drives the spiral teeth to rotate through the worm 331, drives the worm gear 332 to rotate through the spiral teeth, drives the rotating rod 334 to rotate through the worm gear 332, drives the stirring paddle 335 to rotate through the rotating rod 334, and breaks up the clumped fertilizer through the stirring paddle 335, facilitating the uniform spreading of the fertilizer and realizing the uniformity of fertilization. Among them, both the worm gear 332 and the spiral teeth are arranged inside the movable box 33 to prevent the fertilizer from corroding the worm gear 332 and the spiral teeth, resulting in poor meshing. The small clump particles are filtered by the filter plate 36. At the same time, during the rotation of the rotating rod 334, the rotating rod 34 is driven to rotate through the rotating rod 334, the limiting column 341 is driven to rotate through the rotating rod 34. During the rotation of the limiting column 341, the swinging rod 342 is driven to reciprocate by squeezing the limiting port 344. During the reciprocating movement of the swinging rod 342, both ends of the swinging rod 342 slide on the cross bar 343 respectively. The cross bar 343 facilitates breaking up the small clump fertilizer, and at the same time, through the reciprocating movement, it facilitates the feeding of the fertilizer and prevents the fertilizer from blocking the filter plate 36.

[0047] When the harrow teeth 231 pass by, the harrow teeth 231 cover and backfill the soil plowed up by the plowshare 43. Among them, there are large soil clods, which are not only inconvenient for backfilling but also easy to follow the vehicle body 1 forward. Finally, a large number of soil clods accumulate at the bottom of the vehicle body 1, resulting in the vehicle body 1 being unable to move forward. By setting the crushing roller 232, under the guidance of the harrow teeth 231, the soil clods will eventually move towards the middle.
