Description

[0002] In the process of crop planting, soil loosening is a crucial link, which directly affects the development of crop root system and the absorption of water and nutrients in soil. The existing technology usually uses an auger device to loosen the soil, which cuts and turns the soil by using the rotating helical blade.

[0033] Refer to the following Figures 1 to 9 To describe a soil loosening device for agricultural planting provided by the present invention.

[0034] The soil loosening equipment for agricultural planting may generally include: a frame 100 , a traction mechanism 200 , a plurality of first soil loosening rotating shafts 300 , a plurality of second soil loosening rotating shafts 400 , and a transmission mechanism 500 .

[0035] The traction mechanism 200 is mounted on the frame 100 and connected to the main body of the agricultural machine 01, driving the frame 100 to operate synchronously with the agricultural machine 01. Multiple first loosening shafts 300 and multiple second loosening shafts 400 are rotatably mounted on the bottom of the frame 100. The first loosening shafts 300 are provided with multiple first blades 310 and second blades 320 that spiral in the same direction. The multiple first blades 310 and multiple second blades 320 are arranged in an alternating pattern, and the pitch of the first blades 310 is greater than the pitch of the second blades 320. A first notch 330 is formed at the junction of the first blades 310 and the second blades 320. The second loosening shaft 400 is provided with multiple third blades 410 and multiple fourth blades 420 that spiral in the same direction. The multiple third blades 410 and multiple fourth blades 420 are arranged in an alternating pattern, and the pitch of the third blades 410 is greater than the pitch of the fourth blades 420. A second notch 430 is formed at the junction of the third blades 410 and the fourth blades 420. The transmission mechanism 500 is arranged on the frame 100 and is connected to the main body of the agricultural machine 01, and is used to drive the multiple first loosening shafts 300 and the multiple second loosening shafts 400 to rotate.

[0036] like Figure 1As shown, soil loosening equipment used for agricultural planting can generally be mounted on the rear side of agricultural machine 01. When agricultural machine 01 moves, the equipment is driven by traction mechanism 200. The power unit of agricultural machine 01 drives the first and second loosening shafts 300 and 400 via transmission mechanism 500, thereby loosening the soil.

[0037] The solution of this embodiment is to provide a first blade 310 and a second blade 320 on the first loosening shaft 300, and a third blade 410 and a fourth blade 420 on the second loosening shaft 400. The first notch 330 and the second notch 430 are used to cut weeds and other entanglements wrapped around the first loosening shaft 300 and the second loosening shaft 400, thereby improving the loosening effect of the equipment. At the same time, the soil can partially slide down when it is transported to the first notch 330 and the second notch 430, thereby improving the mixing effect of the soil. The staggered arrangement of the first blade 310 and the second blade 320, as well as the staggered arrangement of the third blade 410 and the fourth blade 420, makes the overall loosening effect of the equipment more uniform.

[0038] The pitch of the first blade 310 is set to be greater than that of the second blade 320, and the pitch of the third blade 410 is set to be greater than that of the fourth blade 420. Therefore, during the loosening process, the stronger cutting action of the second blade 320 and the fourth blade 420 is used to improve the degree of soil fragmentation, while the stronger pushing action of the first blade 310 and the third blade 410 is used to improve the degree of soil mixing, thereby improving the overall loosening effect of the device. In addition, the provision of blades with different pitches enables the device to better adapt to different types of soil, thereby ensuring the loosening effect.

[0039] In some preferred embodiments, the ends and edges of the first blade 310, the second blade 320, the third blade 410, and the fourth blade 420 are sharpened to improve the efficiency of the equipment in cutting soil and weeds. The agricultural machine 01 is preferably a tractor.

[0040] At the first notch 330, in the axial direction, the bottom end of the first blade 310 or the second blade 320 is lower than or equal to the top end of the second blade 320 or the first blade 310 adjacent to the bottom thereof. At the second notch 430, in the axial direction, the bottom end of the third blade 410 or the fourth blade 420 is lower than or equal to the top end of the fourth blade 420 or the third blade 410 adjacent to the bottom thereof.

[0041] In the solution of this embodiment, the relative positions of the ends of the first blade 310, the second blade 320, the third blade 410 and the fourth blade 420 are specially set, so that the soil can be cut a second time at the first notch 330 and the second notch 430 during the rising process, thereby improving the degree of soil crushing and improving the loosening effect.

[0042] A plurality of first loosening shafts 300 and a plurality of second loosening shafts 400 are staggered on the frame 100. The first blade 310 and the fourth blade 420 are oppositely arranged, and the second blade 320 and the third blade 410 are oppositely arranged.

[0043] In the solution of this embodiment, the first loosening shaft 300 and the second loosening shaft 400 are staggered, and the first blade 310 and the fourth blade 420 are arranged opposite to each other, and the second blade 320 and the third blade 410 are arranged opposite to each other, so that the second blade 320 and the fourth blade 420 with stronger cutting effect are staggered in the axial direction, and the first blade 310 and the third blade 410 with stronger pushing effect are also staggered in the axial direction, thereby ensuring the overall soil crushing degree and soil mixing degree of the equipment, thereby improving the overall loosening effect of the equipment.

[0044] In some preferred embodiments, the pitch of the first blade 310 may be consistent with the pitch of the third blade 410, and the pitch of the second blade 320 may be consistent with the pitch of the fourth blade 420. The first blade 310 is opposite to the fourth blade 420, and the second blade 320 is opposite to the third blade 410. Due to the different pitches, the first loosening shaft 300 and the second loosening shaft 400 push the soil to move at different speeds, and the forces applied to the soil are also different, so that the soil in the dead angle area between the first loosening shaft 300 and the second loosening shaft 400 is turned and broken by the two shafts, thereby improving the loosening effect.

[0045] During the soil loosening process, when soil on the first blade 310 is partially transferred to the second blade 320 above it, the second blade 320 below the first blade 310 also transfers some soil to the first blade 310. However, due to the different pitches of the first and second blades 310, the soil pressure in the first blade 310 is relatively low. Accordingly, the soil pressure in the fourth blade 420, which is opposite the first blade 310, is relatively high. Therefore, during the soil movement process, some soil in the fourth blade 420 will be scattered onto the first blade 310. The lateral transfer of soil between the adjacent first and second loosening shafts 300, 400 improves the mixing of the soil.

[0046] The first blade 310 and the third blade 410 rotate in opposite directions. The rotation directions of the first loosening shaft 300 and the second loosening shaft 400 are respectively adapted to the rotation directions of the first blade 310 and the second blade 320 to drive the soil to move upward.

[0047] In this embodiment, the rotational directions of the first and third blades 310, 410 are set to opposite directions, causing the two adjacent first and second loosening shafts 300, 400 to rotate in opposite directions. This results in the soil between the first and second loosening shafts 300, 400 being subjected to two opposing forces. This shears and agitates the soil between the first and second loosening shafts 300, 400, improving soil fragmentation. These opposing forces help to better mix and loosen the soil, further enhancing the loosening effect of the device.

[0048] The transmission mechanism 500 generally includes a plurality of first transmission shafts 510 and a plurality of second transmission shafts 520. The plurality of first transmission shafts 510 are connected to the plurality of first loosening shafts 300, and a first transmission gear 511 is provided on the first transmission shaft 510. The plurality of second transmission shafts 520 are connected to the plurality of second loosening shafts 400, and a second transmission gear 521 is provided on the second transmission shaft 520. Adjacent first transmission gears 511 and second transmission gears 521 mesh with each other.

[0049] The solution of this embodiment, by providing the first transmission gear 511 and the second transmission gear 521, utilizes the meshing action of the gears to enable the adjacent first loosening shaft 300 and the second loosening shaft 400 to stably rotate in opposite directions, thereby improving the stability and reliability of the transmission system.

[0050] like Figure 7 As shown, in some preferred embodiments, the first transmission gear 511 and the second transmission gear 521 can be arranged on the support plate 140 of the frame 100. The first transmission gear 511 and the second transmission gear 521 can use straight teeth, which not only has high transmission efficiency, but also has a simple structure and low production cost.

[0051] The transmission mechanism 500 may generally further include: an input shaft 530 , a fourth transmission gear 540 , a first bevel gear 550 , and a second bevel gear 560 .

[0052] One end of the input shaft 530 is connected to the power unit of the agricultural machine 01, and the other end is provided with a third transmission gear 531. The fourth transmission gear 540 is vertically mounted on the frame 100 and meshes with the third transmission gear 531. The first bevel gear 550 is fixedly mounted on a side of the fourth transmission gear 540 near the first transmission shaft 510 or the second transmission shaft 520 and is coaxial with the fourth transmission gear 540. The second bevel gear 560 is mounted on one of the first transmission shafts 510 or the second transmission shaft 520 and meshes with the first bevel gear 550.

[0053] The power of agricultural machine 01 is transmitted to the fourth transmission gear 540 through the input shaft 530 and the third transmission gear 531. It is then transmitted to the second bevel gear 560 through the first bevel gear 550. The second bevel gear 560 is arranged on one of the first transmission shafts 510 or one of the second transmission shafts 520, driving the rotation of one of the first transmission shafts 510 or one of the second transmission shafts 520. This, in turn, drives the remaining first transmission shafts 510 and second transmission shafts 520 to rotate synchronously via the first transmission gear 511 and the second transmission gear 521, thereby ensuring that the multiple first loosening shafts 300 and the multiple second loosening shafts 400 rotate synchronously to loosen the soil.

[0054] The solution of this embodiment adopts a gear meshing transmission method, which not only has high transmission efficiency and stable and reliable operation, but also has strong load-bearing capacity and long service life.

[0055] In some preferred embodiments, multiple first transmission shafts 510 and multiple second transmission shafts 520 are staggered and arranged in a row, and the second bevel gear 560 can be set on the first transmission shaft 510 or the second transmission shaft 520 in the middle position to improve the overall structural stability of the transmission mechanism 500.

[0056] The first loosening shaft 300 and the second loosening shaft 400 are arranged to be tilted in the traction direction of the traction mechanism 200 , and the tilting directions of the first loosening shaft 300 and the second loosening shaft 400 are opposite.

[0057] like Figure 1 As shown, in some embodiments, the top of the first loosening shaft 300 is tilted toward the forward direction of the agricultural machine 01.

[0058] As the agricultural machine 01 moves forward, because the pitch of the first blade 310 is greater than the pitch of the second blade 320, the soil on the first blade 310 is partially transferred to the second blade 320 above it, and the soil pressure on the second blade 320 is greater than the soil strength on the first blade 310. Because the top of the first loosening shaft 300 is tilted toward the forward direction of the agricultural machine 01, the soil with greater pressure on the second blade 320, after separating from the second blade 320, partially slides down toward the area below the first blade 310. The sliding soil is then secondary crushed, thereby improving the loosening effect.

[0059] In the solution of this embodiment, the top of the second loosening shaft 400 is tilted away from the forward direction of the agricultural machine 01, so as to neutralize the soil thrown toward the forward direction of the agricultural machine 01 by the first loosening shaft 300, and avoid excessive accumulation of field ridge soil in the forward direction of the agricultural machine 01 after loosening the soil.

[0060] In addition, the first loosening shaft 300 and the second loosening shaft 400 are cross-wise and tilted to push the soil in different directions, thereby improving the mixing effect of the soil and making the soil more evenly crushed and mixed, thereby improving the loosening effect.

[0061] The soil loosening equipment for agricultural planting may generally further include: a plurality of first mounting cylinders 110 and a plurality of second mounting cylinders 120 .

[0062] Multiple first mounting tubes 110 are arranged at an angle at the bottom of the frame 100, corresponding one-to-one with the multiple first loosening shafts 300. The first loosening shafts 300 pass through the first mounting tubes 110 and are connected to the corresponding first transmission shafts 510 via first universal joints 570. Multiple second mounting tubes 120 are arranged at an angle at the bottom of the frame 100, corresponding one-to-one with the multiple second loosening shafts 400. The second loosening shafts 400 pass through the second mounting tubes 120 and are connected to the corresponding second transmission shafts 520 via second universal joints 580.

[0063] The solution of this embodiment is to install the first loosening shaft 300 and the second loosening shaft 400 on the frame 100 by providing multiple first mounting cylinders 110 and second mounting cylinders 120. At the same time, the cylinders are used to limit the inclination angle of the first loosening shaft 300 and the second loosening shaft 400, thereby reducing the risk of shaking during the rotation of the first loosening shaft 300 and the second loosening shaft 400. The first universal joint 570 and the second universal joint 580 are used to connect the first transmission shaft 510 and the second transmission shaft 520 to the first loosening shaft 300 and the second loosening shaft 400, respectively, so that the power from the vertically arranged first transmission shaft 510 and the second transmission shaft 520 is smoothly transmitted to the inclined first loosening shaft 300 and the second loosening shaft 400.

[0064] In some preferred embodiments, the first mounting tube 110 and the second mounting tube 120 extend obliquely downward from the bottom plate 130 of the frame 100 . The first mounting tube 110 and the second mounting tube 120 are integrally formed with the frame 100 , further improving the structural stability of the equipment.

[0065] The first loosening shaft 300 can generally include a first connecting shaft 340 and a first rotating shaft 350. The first connecting shaft 340 passes through the first mounting tube 110 and abuts against the bottom plate 130 of the frame 100. One end of the first connecting shaft 340 is connected to the first universal joint 570, and the other end is connected to the first rotating shaft 350. The second loosening shaft 400 can generally include a second connecting shaft 440 and a second rotating shaft 450. The second connecting shaft 440 passes through the second mounting tube 120 and abuts against the bottom plate 130 of the frame 100. One end of the second connecting shaft 440 is connected to the second universal joint 580, and the other end is connected to the second rotating shaft 450.

[0066] like Figure 7 As shown, the sidewalls of the first connecting shaft 340 and the second connecting shaft 440 may be provided with an annular stepped surface that abuts against the bottom plate 130 of the frame 100, thereby preventing the first connecting shaft 340 and the second connecting shaft 440 from falling out from under the first mounting cylinder 110 and the second mounting cylinder 120. The first blade 310 and the second blade 320 are disposed on the first rotating shaft 350, and the third blade 410 and the fourth blade 420 are disposed on the second rotating shaft 450. The tops of the first rotating shaft 350 and the second rotating shaft 450 may be provided with mounting holes, through which fasteners extend into the first connecting shaft 340 or the second connecting shaft 440, thereby connecting the first rotating shaft 350 and the first connecting shaft 340 together, and connecting the second rotating shaft 450 and the second connecting shaft 440 together.

[0067] In the solution of this embodiment, the first loosening shaft 300 and the second loosening shaft 400 are set as two detachable parts, thereby reducing the difficulty of installation of the first loosening shaft 300 and the second loosening shaft 400 and the difficulty of subsequent maintenance and replacement.

[0068] In other embodiments, the first rotating shaft 350 , the second rotating shaft 450 and the corresponding first connecting shaft 340 , the second connecting shaft 440 may be connected together by snapping.

[0069] The traction mechanism 200 may generally include: a support frame 210 and a pull rod 220 .

[0070] A support frame 210 is mounted on top of the frame 100 and is shaped like an inverted V. A pull rod 220 has one end connected to the control device of the agricultural machine 01 and the other end hinged to the top of the support frame 210, pulling the frame 100 and moving it along with the agricultural machine 01. Furthermore, the pull rod 220 is configured to rotate under the control of the agricultural machine 01's control device, driving the frame 100 up and down.

[0071] In this embodiment, an inverted V-shaped support frame 210 is positioned on top of the frame 100, forming a triangular shape, thereby improving the structural stability of the equipment. A pull rod 220 is hingedly connected to the support frame 210, ensuring that the support frame 210 remains in an upright position when the pull rod 220 drives the support frame 210 up or down.

[0072] The specific working process of the soil loosening equipment for agricultural planting provided by the present invention is described in combination with the above embodiments:

[0073] The input rotating shaft 530 is started under the drive of the power device of the agricultural machine 01, and drives the third transmission gear 531 to rotate. The third transmission gear 531 drives the fourth transmission gear 540 and the first bevel gear 550 to rotate. The first bevel gear 550 drives the second bevel gear 560 and the corresponding first transmission shaft 510 or the second transmission shaft 520 to drive. When the first transmission shaft 510 or the second transmission shaft 520 provided with the second bevel gear 560 rotates, the remaining first transmission shaft 510 and the second transmission shaft 520 are driven to rotate synchronously through the first transmission gear 511 and the second transmission gear 521. When the first transmission shaft 510 and the second transmission shaft 520 rotate, the first soil loosening rotating shaft 300 and the second soil loosening rotating shaft 400 are driven to rotate through the first universal joint 570 and the second universal joint 580.

[0074] The traction mechanism 200 drives the frame 100 to descend under the control of the control device of the agricultural machine 01, so that the first soil loosening rotating shaft 300 and the second soil loosening rotating shaft 400 are inserted into the soil. After the first soil loosening rotating shaft 300 and the second soil loosening rotating shaft 400 are inserted into the soil, the agricultural machine 01 starts to move, and the frame 100 moves synchronously with the agricultural machine 01 under the drive of the traction mechanism 200.

[0075] During the descent of the frame 100 and the movement of the frame 100 with the agricultural machine 01, the first soil loosening rotating shaft 300 and the second soil loosening rotating shaft 400 continuously rotate, and the first blade 310, the second blade 320, the third blade 410 and the fourth blade 420 cut and push the soil to move axially, so that the soil is loosened and mixed together.

[0076] After the agricultural machine 01 stops moving, the traction mechanism 200 drives the frame 100 to ascend under the control of the control device of the agricultural machine 01. The first soil loosening rotating shaft 300 and the second soil loosening rotating shaft 400 stop rotating after leaving the soil, and the soil loosening is completed.
