As an important agricultural machine in modern agriculture that improves soil condition and structure through physical intervention, soil rippers play an irreplaceable role in improving arable land quality and promoting crop yields.

[0003] Chinese patent document CN222216371U discloses a soil loosening device for agricultural planting. Through the cooperation of a connecting mechanism, an extension plate, a soil loosening blade, a fixing block, a fixing spring, a fixing sleeve, an insertion rod, and a threaded sleeve, the adjustment mechanism can adjust the left and right swing amplitude of the soil loosening blade according to different conditions, thereby adapting to different soil and crop planting needs and improving the soil loosening effect.

[0004] However, in the existing technology, although the loosening range can be expanded by slightly swinging the loosening blade during walking to improve the work effect, the swing trajectory of each loosening blade cannot be completely connected due to the distance between their installation positions, which makes it easy for uncovered gaps to appear in the work area. Therefore, a loosening device for agricultural planting is proposed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0032] like Figures 1-6 As shown, an agricultural soil loosening device includes a movable component 1 that can adjust the loosening depth of the soil loosening device, a soil loosening component 2 that can fully loosen and break up compacted soil is provided inside the movable component 1, and a drive component 3 that can provide power for the operation of the soil loosening component 2 is provided above the soil loosening component 2.

[0033] In this embodiment: the moving component 1 includes a frame 101, a commutator 102 is movably connected to the lower side of one side of the frame 101, a damping shock absorber 103 is fixedly connected to the lower side of the other side of the frame 101 and the lower side of the commutator 102, a roller 104 is fixedly connected to the lower side of the damping shock absorber 103, and a hydraulic cylinder 105 is movably installed between the frame 101 and the commutator 102.

[0034] The frame 101 and the hydraulic cylinder 105 are both rotatably connected to the reversing frame 102, and the reversing frame 102 is rotatably connected to the hydraulic cylinder 105.

[0035] The frame 101 connects to agricultural machinery with traction function and provides installation positions for components such as the reversing frame 102, hydraulic cylinder 105, first support 201, support rod 206, limit rod 210, second support 301, drive unit 303, and third support 304. The overall tilt of the ripper can be varied by the reversing frame 102, which can be adjusted by the hydraulic cylinder 105, thereby changing the soil penetration depth of the ripper blade 204. The damping shock absorber 103 enables the ripper to operate more stably, and the rollers 104 make the ripper easy to move under external forces.

[0036] In this embodiment: the soil loosening component 2 includes a soil loosening part that can be continuously inserted into compacted soil, a transmission part that can be continuously oscillated by the drive component 3, and a toggle part that can continuously adjust the soil insertion position of the soil loosening part under the action of the transmission part.

[0037] The soil loosening component includes first supports 201 fixedly installed at the front and rear of the frame 101, respectively. A rib 202 is movably connected between the two first supports 201. Multiple cutter heads 203 are movably connected to the outer side of the rib 202. Multiple soil loosening blades 204 are fixedly connected to the outer side of the cutter heads 203. Annular grooves 205 are integrally formed on the front and rear sides of the cutter heads 203. The actuating component includes a support rod 206 disposed above the rib 202 and fixedly connected to the frame 101. The outer side of the support rod 206... The surface is movably connected to multiple actuating frames 207 located above the cutter head 203. Ball head rods 208 fixedly connected to the actuating frames 207 are provided at the front and rear of the cutter head 203. Insert rods 209 are fixedly connected above the actuating frames 207. The transmission component includes limiting rods 210 located above the support rod 206 and fixedly installed at the front and rear of the frame 101. A limiting frame 211 is movably connected between the two limiting rods 210. Multiple limiting grooves 212 are provided on the limiting frame 211.

[0038] Multiple cutterheads 203 are equidistantly arranged along the length of the rib 202, and multiple loosening blades 204 are equidistantly spaced around the axis of the cutterheads 203. A first support 201 is rotatably connected to the rib 202, and the rib 202 is slidably connected to the cutterheads 203. The number of cutterheads 203, actuating frames 207, and limiting grooves 212 are equal. An annular groove 205 matches the outer contour of the ball head of a ball-head rod 208, which is inserted into the annular groove 205. The cutterheads 203 and ball-head rods 208 are slidably connected. (The last sentence appears to be incomplete and possibly refers to a support rod.) 206 is slidably connected to the actuating frame 207. The frame 101, the insert rod 209, and the limiting rod 210 are all slidably connected to the limiting frame 211. The limiting groove 212 fits the outer contour of the insert rod 209. The insert rod 209 passes through the limiting groove 212. The length direction of the limiting groove 212 located in the middle of the length direction of the limiting frame 211 is orthogonal to the length direction of the prism 202. The angle between the length direction of the other limiting grooves 212 and the length direction of the limiting groove 212 located in the middle is an acute angle.

[0039] The first support 201 installs the rib 202, which is fitted with multiple cutter heads 203, inside the frame 101, so that the rib 202 can drive the cutter head 203 to rotate continuously under the action of external force. The loosening blade 204, which can rotate with the cutter head 203, contacts and breaks up the compacted soil. The support rod 206 limits the movable range of the actuating frame 207 located above the cutter head 203. The ball head rod 208 inserted into the annular groove 205 transmits the position change of the actuating frame 207 along the length direction of the support rod 206 to the cutter head 203 without affecting the rotation of the cutter head 203. The limiting frame 211 is installed above the actuating frame 207 by the limiting rod 210. The insert rod 209 inserted into the limiting groove 212 transmits its own position change along the length direction of the support rod 206 to the actuating frame 207 when the limiting frame 211 moves along the length direction of the limiting rod 210.

[0040] In this embodiment: the drive assembly 3 includes a second support 301 located above the limiting rod 210 and fixedly installed inside the frame 101. A long shaft 302 is movably connected between the two second supports 301. A drive unit 303 is fixedly connected to one end of the long shaft 302. A third support 304 is fixedly installed on the frame 101 above the limiting groove 212 at the center of the length direction of the limiting frame 211. A short shaft 305 is movably connected inside the third support 304 and passes through it. An active bevel gear 306 is fixedly connected to the outer side of the long shaft 302. A driven bevel gear 307 is fixedly connected to the upper end of the short shaft 305. A cam 308 is fixedly connected to the lower end of the short shaft 305. A connecting rod 309 is movably installed between the limiting frame 211 and the cam 308. A pulley set 310 is provided between the prism 202 and the long shaft 302.

[0041] The second support 301 is rotatably connected to the long shaft 302, the third support 304 is rotatably connected to the short shaft 305, the driving bevel gear 306 is meshed with the driven bevel gear 307, and the limit frame 211 and the cam 308 are rotatably connected to the connecting rod 309.

[0042] The long shaft 302, whose axis is parallel to the axis of the rib 202, is installed in the frame 101 via the second support 301. The long shaft 302 is driven to rotate relative to the second support 301 via the drive unit 303, which may consist of a motor and a reducer. The short shaft 305, whose axis is perpendicular to the axis of the long shaft 302, is installed via the third support 304. The rotation of the long shaft 302 is transmitted to the short shaft 305 via the driving bevel gear 306 and the driven bevel gear 307. The rotation of the short shaft 305 is transmitted to the limiting frame 211 via the cam 308 and the connecting rod 309, so that the limiting frame 211 can continuously swing along the length direction of the limiting rod 210 due to the rotation of the short shaft 305. The rotation of the long shaft 302 is transmitted to the rib 202 via the pulley group 310, which consists of pulleys connected to the rear ends of the rib 202 and the long shaft 302 respectively and a belt disposed between the two pulleys.

[0043] Working principle: When this soil ripper is installed and put into use, after the frame 101 is connected to the agricultural machinery with traction function, the tilt of the reversing frame 102 can be adjusted by the operation of the hydraulic cylinder 105, thereby adjusting the soil penetration depth of the ripper 204. Then, when the agricultural machinery moves and drives this soil ripper, the drive unit 303 will run to complete the soil ripping work.

[0044] Specifically, when the drive unit 303 drives the long shaft 302 to rotate after operation, the rotation of the long shaft 302 is transmitted to the rib bar 202 through the pulley group 310, so that the rib bar 202 can drive each cutter head 203 and the loosening blade 204 to rotate around its axis. Since the rotation of the long shaft 302 is also transmitted to the limit frame 211 through the driving bevel gear 306, the driven bevel gear 307, the short shaft 305, the cam 308, and the connecting rod 309, the limit frame 211 continuously swings relative to the limit rod 210. When the limit frame 211 swings, the limit groove 2, which is inserted into the middle position of the length direction of the limit frame 211, is inserted into the limit groove 2. The longitudinal position of the insertion rod 209 in 12 will not change, but the insertion rod 209 inserted into other limiting slots 212 will cause the corresponding connecting actuating frame 207 to swing along the length direction of the support rod 206 due to the swing of the limiting frame 211. Simultaneously, the aforementioned actuating frame 207 will drive the corresponding cutter head 203 to swing along the length direction of the ridge rod 202 through the ball head rod 208. Therefore, most of the loosening blades 204 will swing along the length direction of the ridge rod 202 as the cutter head 203 rotates around the axis of the ridge rod 202, thereby making more full contact with and breaking up the compacted soil located below the coverage area of ​​the frame 101.

[0045] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
