Description

Technical Field

[0001] This utility model relates to the field of agricultural seeding machine technology, and in particular to a furrowing shovel device for a wheat breeding seeding machine. Background Technology

[0002] In wheat breeding in small-scale planting, the seed spacing needs to be within the theoretical range, with a spacing of 0.5 to 1.5 times the theoretical spacing considered acceptable. Due to the small size of wheat seeds, they bounce when sown in the furrow, making it difficult to achieve the theoretical spacing. Currently, wheat breeding in major universities primarily uses manual methods, not machinery, mainly because controlling the seed spacing is difficult. While existing devices, such as the Chinese utility model patent with patent number CN108834494 A, do achieve some success in basic functions like furrow opening, fulfilling certain soil preparation requirements before wheat sowing, they exhibit significant shortcomings in the most crucial sowing stage: precisely placing the seeds into the corresponding furrows. In actual sowing, due to the lack of an effective control mechanism for seed landing point, seeds are easily affected by external factors after leaving the sowing device, deviating from the predetermined seed furrow position. This results in a large number of seeds failing to fall accurately into the seed furrow, which not only directly affects the sowing accuracy but also leads to uneven germination, emergence, and plant growth of subsequent wheat seeds, severely reducing the overall quality after planting and failing to meet the strict requirements of high-precision sowing for wheat breeding in small plots.

[0003] In view of this, there is an urgent need to develop a new type of furrowing shovel device for wheat breeding seeders. This device should not only be able to overcome the bouncing problem caused by the small size of wheat seeds and accurately control the seed spacing, but also ensure that the seeds can be accurately sown into the corresponding furrows, thereby improving the quality and efficiency of wheat breeding sowing and meeting the increasingly stringent technical requirements of modern wheat breeding research for the sowing process.

A driven gear 13 is fixedly connected to the end; the upper outer side of the movable seat 8 is vertically movably connected to the inside of the guide hole 9, and the threaded hole in the center of the movable seat 8 is connected to the screw 10. A furrowing shovel 7 is fixedly connected to the bottom of the movable seat 8; the release mechanism 3 is located inside the lower right side of the seeder seat 1, and the left side of the release mechanism 3 is connected to the drive shaft 5. The upper right inlet of the release mechanism 3 is connected to the lower outlet of the seeding tube 2; the driving gear 12 is movably connected inside the upper left side of the seeder seat 1, and the driving gear 12 is connected to the driven gear 13. An adjusting head 11 is fixedly connected to the central shaft on the left side of the driving gear 12.

[0017] like Figure 2 As shown, the specific structure of the release mechanism 3 includes a turntable 31, a locking screw 32, a drive groove 33, a wheel 34, a slider 35, a guide groove cavity 36, a fixed housing 37, a rack 38, a pinion 39, a connecting shaft 310, a valve plate 311, a valve hole 312, a spring 313, and an output pipe 314. The turntable 31 is fixedly connected to the transmission shaft 5 in the center by a locking screw 32. Several drive grooves 33 are evenly distributed on the outside of the turntable 31, and the number of drive grooves 33 is equal to the number of protrusions 6. The fixed housing 37 is fixedly connected to the lower right side of the seeder base 1. The front side of the fixed housing 37 has a guide groove cavity 36, and the rear right side of the fixed housing 37 has a valve hole 312. The slider 35 is... The slider 35 is laterally movably connected inside the guide groove cavity 36. A wheel 34 is movably connected inside the left side of the slider 35, and the left side of the wheel 34 is connected to the outside of the turntable 31. A rack 38 is fixedly connected to the upper inside of the right side of the slider 35. A spring 313 is provided between the right side of the slider 35 and the right side of the guide groove cavity 36. The upper opening of the valve hole 312 is connected to the lower outlet of the seeding tube 2. An output tube 314 is fixedly connected to the lower opening of the valve hole 312. A connecting shaft 310 is movably connected to the left center of the valve hole 312, and the outer center of the connecting shaft 310 is fixedly connected to the inner left side of the valve plate 311. The inner center of the pinion 39 is fixedly connected to the outer front side of the connecting shaft 310, and the pinion 39 is connected to the rack 38.

[0018] The output tube 314 is inclined; the guide hole 9 is a rectangular guide hole; and the adjustment head 11 has an internal hexagonal hole in the center of its left side.

[0019] The utility model is used as follows: It features a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, first, install the seeder base 1 in the corresponding position on the seeder, ensuring a stable installation. Connect the seeding tube 2 to the seed storage device and other relevant parts, allowing the seeds to smoothly pass through the seeding tube 2 and enter the release mechanism 3. Since the guide hole 9 is vertically located inside the lower left side of the seeder base 1, the screw 10 is movably connected to the center of the guide hole 9, and the upper end of the screw 10 is fixedly connected to the driven gear 13. The upper outer side of the movable seat 8 is vertically movably connected inside the guide hole 9, and its threaded hole is connected to the screw 10. A furrowing shovel 7 is fixedly connected to the bottom. When it is necessary to adjust the depth of the furrowing shovel 7, rotate the adjusting head 11. The adjusting head 11 is located on the left side... The drive gear 12, fixedly connected to the spindle, rotates accordingly. The drive gear 12 meshes with the driven gear 13, driving the driven gear 13 to rotate, which in turn causes the screw 10 to rotate. Since the movable seat 8 is connected to the screw 10 via threads, the rotation of the screw 10 causes the movable seat 8 to move up and down within the guide hole 9, thereby adjusting the height of the furrowing shovel 7 to adapt to different sowing depth requirements. Because the guide hole 9 is a rectangular guide hole, it can provide good guidance for the movable seat 8, ensuring its stable up and down movement. The adjustment head 11 has an internal hexagonal hole in the center of its left side, which facilitates operation with tools such as an internal hexagonal wrench, improving the convenience and accuracy of adjustment. When the seeder starts to move, the drive shaft 5 begins to rotate under the drive of external power, and the roller shaft 4 fixedly connected to the outside of the drive shaft 5 rotates accordingly. As the roller 4 rotates, several protrusions 6 evenly arranged on its outer side also rotate, thus pressing out equidistant grooves in the trench opened by the trenching shovel 7. At the same time, the release mechanism 3 starts to work. In the release mechanism 3, the center of the turntable 31 is fixedly connected to the drive shaft 5 by a locking screw 32, so the turntable 31 will rotate synchronously with the drive shaft 5. The several driving protrusions 33 evenly arranged on the outer side of the turntable 31 will also rotate. During the rotation, the driving protrusions 33 will intermittently push the wheel 34, causing the slider 35 to make lateral reciprocating motion in the guide groove cavity 36. The rack 38 fixedly connected to the upper side of the right side of the slider 35 will move with the slider 35. The rack 38 meshes with the pinion 39, thereby driving the pinion 39 to rotate. The small gear 39 is fixedly connected internally to the outside of the front side of the connecting shaft 310, so the connecting shaft 310 will also rotate, thereby driving the valve plate 311 fixedly connected to the outside of the center of the connecting shaft 310 to rotate within the valve hole 312. When the valve plate 311 rotates to a specific position, the lower outlet of the sowing tube 2 connects with the valve hole 312, and the seeds enter the valve hole 312 from the sowing tube 2, and then fall sequentially into the seed grooves pressed out by the protrusions 6 through the inclined output tube 314. In addition, since the number of driving protrusions 33 is equal to the number of protrusions 6, it ensures that the sowing distance is equal to the distance between the seed grooves pressed out by the protrusions 6, thus meeting the needs of precise sowing and avoiding the phenomenon of the inserted seeds bouncing in the seed grooves. During the lateral movement of the slider 35,The spring 313 between the right side of slider 35 and the right side of guide cavity 36 acts as a buffer and reset mechanism, ensuring that slider 35 can reciprocate stably and guaranteeing the stability and uniformity of seed release.
