Technical Field
[0001] This utility model relates to the field of rapeseed planting technology, specifically to a soil loosening device for rapeseed planting that facilitates depth adjustment. Background Technology
[0002] In rapeseed cultivation, different varieties have varying requirements for soil loosening depth. These requirements are influenced by multiple factors, such as soil type, rapeseed growth stage, and planting density. Generally, in areas with compacted soil, deeper loosening is needed to enhance permeability and promote effective water and nutrient penetration; while in relatively loose soil areas, shallow loosening is sufficient to meet the rapeseed's growth needs.
[0003] Utility model patent CN214155292U discloses a soil loosening device for rapeseed planting, comprising a fixed base, the bottom outer wall of which is fixedly connected to a hydraulic rod, and the bottom outer wall of the hydraulic rod is fixedly connected to a support plate; one side of the bottom outer wall of the support plate is rotatably connected to a rotating rod via a bearing, a connecting plate is fixedly attached to the bottom outer wall of the rotating rod, and multiple loosening teeth are fixedly installed on the bottom outer wall of the connecting plate; simultaneously, multiple springs are installed on one side of the bottom outer wall of the support plate, the bottom outer wall of the springs is fixedly connected to a protective cover, and fixing frames are fixed to the two outer walls of the protective cover; the design of this device can effectively prevent soil from splashing due to the force generated during the loosening process, thereby avoiding soil loss and adverse effects on rapeseed planting.
[0004] However, the existing technology cannot flexibly adjust the depth of soil loosening according to needs, and its application scope is limited. At the same time, the existing technology cannot guarantee that rapeseed seeds fall evenly into the soil during the rapeseed planting process, which can easily lead to uneven sowing and thus affect the rapeseed yield.

The second planting gear 305 is fixedly disposed on the first planting roller 302, and the first planting gear 304 is fixedly disposed on the second planting roller 303. The first planting gear 304 and the second planting gear 305 mesh. The first planting connecting rod 306 is fixedly disposed on both sides of the second planting roller 303, and the second planting connecting rod 307 is rotatably disposed on the other end of the first planting connecting rod 306. The planting trough 308 is rotatably mounted on the planting feed trough 308, which is slidably mounted on the outer casing 4. A planting blade 311 is rotatably mounted inside the planting feed trough 308, and a planting gear 310 is fixedly mounted on the planting blade 311. The planting gear 310 meshes with a planting rack 309 fixedly mounted on the outer casing 4. A strip-shaped material outlet is provided at the bottom of the planting feed trough 308. A planting roller 302 is fixedly mounted on the output shaft of the planting motor 301. A soil covering part 5 is provided on the output shaft of the planting motor 301. The soil covering part 5 includes a soil covering conveyor belt 501 mounted on the output shaft of the planting motor 301. The soil covering conveyor belt 501 is connected to a soil covering wheel 502, which is rotatably mounted on the outer casing 4. A movable wheel is provided at the bottom of the outer casing 4, and the movable wheel is driven by a drive motor to move the device.
[0027] like Figures 1 to 9As shown, this utility model discloses a soil loosening device for rapeseed planting with adjustable soil loosening depth. Its working principle is as follows: The adjusting motor 202 is turned on, causing the adjusting roller 201 to rotate. The rotating roller 201 causes multiple loosening blades 101 to rotate together with the adjusting roller 201, loosening the soil. During this process, the soil loosening depth can be changed according to requirements. Specifically, the adjusting cylinder 203 is turned on, pushing the adjusting slide rod 204 to move. When the adjusting slide rod 204 moves, the annular inclined surface on the adjusting slide rod 204 forces the loosening blades 101 to slide, thereby changing the radial position of the loosening blades 101 on the adjusting roller 201, increasing the contact depth between the loosening blades 101 and the soil, thus achieving easy adjustment of the soil loosening depth.
[0028] After the loosening blade 101 is adjusted, the rotating adjusting roller 201 and the loosening blade 101 loosen the soil. The planting motor 301 is then turned on, driving the planting roller 302 and the soil-covering conveyor belt 501. The rotation of the planting roller 302 drives the planting gear 305, which in turn drives the planting roller 303 via the planting gear 304. As the planting rollers 302 and 303 rotate, the circular groove on the planting roller 302 engages with the cylinder on the planting roller 303, quantitatively conveying rapeseed seeds into the planting trough 308. Specifically, when the circular groove on the planting roller 302 faces upwards, the rapeseed seeds fall into the groove. When the planting roller 302 rotates, the cylinder on the planting roller 303 covers the circular groove on the planting roller 302. When the circular groove on the planting roller 302 faces downwards, it detaches from the cylinder and falls into the planting trough 308 under gravity.
[0029] When the planting roller 303 rotates, it drives the planting connecting rod 306. The planting connecting rod 306 pulls the planting feed trough 308 to slide through the planting connecting rod 307. At this time, the planting gear 310 meshes with the planting rack 309, driving the planting blades 311 to rotate. The rotation of the planting blades 311 causes the rapeseed seeds falling into the planting feed trough 308 to fall evenly from the bottom of the planting feed trough 308 into the loosened soil of the loosened part 1, completing the sowing of rapeseed seeds. When the planting motor 301 rotates, it drives the soil covering conveyor belt 501, which in turn drives the soil covering wheel 502 to rotate. The rotation of the soil covering wheel 502 covers the rapeseed seeds with the soil after sowing, completing the entire rapeseed planting work.
