An inner furrow opener 6 is provided in the middle of the mounting tube 19, and outer furrow openers 5 are provided on both sides of the inner furrow opener 6. A shovel plate 14 is provided on the frame 1 to cooperate with the inner furrow opener 6 and the outer furrow openers 5. A bulldozing mechanism 17 is provided between the inner furrow opener 6 and the outer furrow openers 5. The bulldozing mechanism 17 includes multiple mounting plates 27 that are detachably connected to the mounting tube 19. A drive cylinder 38 is slidably connected to the mounting plate 27. An arc-shaped rod 29 rotates on the drive cylinder 38, and a fan-shaped bulldozing plate 30 is rotatably connected to the mounting plate 27. The other end of the arc-shaped rod 29 is rotatably connected to the middle of the bulldozing plate 30.
[0018] In use, the present invention uses rotary tillage blades on the shaft tube 4 to till the soil. The shaft tube 4 opens furrows through the inner furrow opener 6 and outer furrow opener 5 on the mounting tube 19, and the shovel plate 14 shapes the furrows. When soil adheres to the shaft tube 4 and the mounting tube 19, the soil can be easily cleaned through the upper opening on the frame 1. The soil can also be cleaned through the bulldozing mechanism 17, making it easier to clean the soil on the shaft tube 4 and the mounting tube 19 and improving the convenience of the present invention. In use, the bulldozing mechanism 17 drives the drive cylinder 38 to slide along the mounting plate 27. The drive cylinder 38 drives the bulldozing plate 30 to rotate through the arc rod 29. The bulldozing plate 30 pushes down the adhered soil, separating the soil from the mounting tube 19. In addition, the arc rod 29 can divide the soil to improve the bulldozing effect of the bulldozing plate 30.
[0019] Furthermore, the frame 1 is equipped with a transmission box 7 connected to the tractor, and the output end of the transmission box 7 is connected to a universal coupling 8; the other end of the universal coupling 8 is connected to a drive wheel 9, and a first idler wheel 10 is engaged on the drive wheel 9; a second idler wheel 11 is engaged on the first idler wheel 10, and a driven wheel 12 coaxially fixed to the shaft tube 4 is engaged on the second idler wheel 11; the tractor drives the drive wheel 9 to rotate through the transmission box 7 and the universal coupling 8, and the drive wheel 9 drives the shaft tube 4 to rotate continuously through the first idler wheel 10, the second idler wheel 11, and the driven wheel 12; the frame 1 is also equipped with a transmission box 7 to protect the drive wheel 9, the first idler wheel 10, the second idler wheel 11, and the driven wheel 12.
[0020] Furthermore, a middle wing plate 16 for leveling both sides of the trench is fixed to the shovel plate 14, and an upper wing plate 15 for guiding the soil is fixed to the frame 1. The upper wing plate 15 guides the soil in the trench to one side. A pair of leveling plates 13 for leveling the soil after rotary tillage are provided on the frame 1, and the pair of leveling plates 13 are respectively provided on both sides of the shovel plate 14.
[0021] Furthermore, a main shaft 18 is rotatably connected to the shaft tube 4, and a connecting structure that cooperates with the shaft tube 4 is provided on the main shaft 18. The main shaft 18 is connected to the shaft tube 4 through the connecting structure to lock the main shaft 18. A driving structure that drives the driving cylinder 38 to move is connected to the main shaft 18, and a disassembly structure that is connected to the driving cylinder 38 is connected to the driving structure.
[0022] Furthermore, the connection structure includes a splined shaft 20 fixedly connected to the main shaft 18, a splined cylinder 21 slidably connected to the splined shaft 20; a fixed plate 22 fixedly connected to the splined cylinder 21, a knob 24 fixedly connected to the fixed plate 22; a fixed plate fixedly connected to the shaft tube 4, a fixing bolt 23 fixedly connected to the fixed plate, a through hole on the fixed plate 22 that mates with the fixing bolt 23, a fixing nut on the fixing bolt 23 that mates with the fixed plate 22; a limit post 25 fixedly connected to the fixed plate 22, a limit hole on the fixed plate that mates with the limit post 25.
[0023] When the spindle 18 is connected to the shaft tube 4, the fixed plate 22 is pushed, causing the splined cylinder 21 to slide along the splined shaft 20. This allows the through hole on the fixed plate 22 to align with the mounting bolt 23. The limiting post 25 is installed in the limiting hole of the fixed plate. The fixed plate 22 is then fixed by the cooperation of the fixing nut and the fixing bolt 23. Figure 5 As shown, this achieves the purpose of limiting and fixing the main shaft 18 through the splined cylinder 21 and splined shaft 20.
[0024] When the main spindle 18 separates from the spindle tube 4, such as Figure 5 As shown, remove the fixing nut and pull the fixing plate 22 in the opposite direction to separate the through hole on the fixing plate 22 from the fixing bolt 23 and the limiting post 25 from the limiting hole; at this time, the fixing plate 22 can be rotated by the knob 24, and the fixing plate 22 drives the main shaft 18 to rotate through the splined cylinder 21 and the splined shaft 20.
[0025] Furthermore, the drive structure includes a crank 31 fixedly connected to the main shaft 18, and a connecting rod 32 rotatably connected to the crank 31; a sliding seat 33 is rotatably connected to the connecting rod 32, and the drive cylinder 38 is detachably connected to the sliding seat 33. A guide rod 35 is fixedly connected inside the shaft tube 4, and the sliding seat 33 is slidably connected to the guide rod 35. When the main shaft 18 rotates, the main shaft 18 drives the connecting rod 32 to rotate through the crank 31, and the crank 31 drives the sliding seat 33 to slide along the guide rod 35 through the connecting rod 32. The sliding seat 33 drives the drive cylinder 38 to move, thereby realizing the action of the bulldozer blade 30 and the arc-shaped rod 29 to perform bulldozing operation.
[0026] Furthermore, the disassembly structure includes a rotating rod 37 rotatably connected to the drive cylinder 38, and a nut fixedly connected to the rotating rod 37; a connecting seat 34 is fixedly connected to the rotating rod 37, and a threaded post 36 screwed to the connecting seat 34 is fixedly connected to the sliding seat 33.
[0027] When the drive cylinder 38 is connected to the sliding seat 33, the connecting seat 34 is aligned with the threaded post 36. The nut is rotated by a wrench, and the nut drives the connecting seat 34 to connect with the threaded post 36 through the rotating rod 37. This enables the drive cylinder 38 and the sliding seat 33 to be detachably connected through the disassembly structure, which facilitates the maintenance of this application.
[0028] Furthermore, a mounting base 26 is fixedly connected to the mounting plate 27, and the mounting tube 19 has a mounting hole that mates with the mounting base 26. The mounting base 26 mates with the mounting hole to limit the installation of the mounting plate 27. A mounting bolt 28 passes through the mounting base 26, and the shaft tube 4 has a threaded hole that mates with the mounting bolt 28. The mounting bolt 28 mates with the threaded hole to perform the installation. Specifically, as shown... Figure 9 As shown, the mounting bolt 28 is coaxially arranged with the drive cylinder 38, and the mounting bolt 28 is provided with a through hole corresponding to the drive cylinder 38.
[0029] Furthermore, the bulldozer blades 30 are provided in pairs, and the pair of bulldozer blades 30 are respectively provided at both ends of the mounting plate 27; by providing a pair of bulldozer blades 30, the soil is squeezed by the pair of bulldozer blades 30 during use, so as to facilitate soil separation.
[0030] Furthermore, the frame 1 is provided with multiple sleeves, and a support tube is inserted through each of the multiple sleeves; both the sleeves and the support tubes are provided with support holes, and a support rod is inserted through the support holes; the sleeves, support tubes, and support rods cooperate to support the application in its non-working state, thereby improving the stability of the application; the frame 1 is provided with a gantry 2 connected to a tractor.
[0031] like Figures 1 to 9 As shown below, the working process of the present invention will be explained in detail.
[0032] In use, the gantry 2 and gearbox 3 are connected to the tractor. The tractor drives the drive wheel 9 to rotate through the transmission box 7 and universal coupling 8. The drive wheel 9 drives the shaft tube 4 to rotate continuously through the first idler wheel 10, the second idler wheel 11, and the driven wheel 12. The rotary tiller blades on the shaft tube 4 perform rotary tillage on the soil. The shaft tube 4 opens trenches through the inner trencher 6 and the outer trencher 5 on the mounting tube 19. The trenches are shaped by the shovel plate 14. The middle wing plate 16 levels the sides of the trenches. The upper wing plate 15 guides the soil in the trenches to one side. The leveling plate 13 levels the soil after rotary tillage.
[0033] When soil adheres to the shaft tube 4 and mounting tube 19, the soil can be easily cleaned from the shaft tube 4 through the upper opening on the frame 1; for example Figure 5As shown, remove the fixing nut and pull the fixing plate 22 in the opposite direction to separate the through hole on the fixing plate 22 from the fixing bolt 23 and the limiting post 25 from the limiting hole; at this time, the fixing plate 22 can be rotated by the knob 24, and the fixing plate 22 drives the main shaft 18 to rotate through the splined cylinder 21 and the splined shaft 20.
[0034] The main shaft 18 drives the connecting rod 32 to rotate via the crank 31. The crank 31 drives the sliding seat 33 to slide along the guide rod 35 via the connecting rod 32. The sliding seat 33 drives the drive cylinder 38 to move. The drive cylinder 38 drives the bulldozer blade 30 to rotate via the arc rod 29. The pair of bulldozer blades 30 compress the soil to facilitate soil separation. In addition, the arc rod 29 can be used to divide the soil to improve the bulldozing effect of the bulldozer blade 30.
