Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] As shown in Figures 1 to 5, this application provides a quantitative seeding device for agricultural planting. The main body of the device 100 includes a support frame 10, a traction frame 20, a furrow opener 30, wheels 50, and a seed storage box 80. A controller is installed on the top of the support frame 10. A connecting rod 60 is connected to the middle of the wheels 50, and a seeding tray 70 is installed in the middle of the connecting rod 60. The seed storage box 80 has a seeding hole 90 inside. An adjustment component 40 is set at the connection between the support frame 10 and the furrow opener 30, including an adjustment column 41 set on the upper end of the furrow opener 30. The top of 41 is connected to a limit plate 42. The outer side of the adjusting column 41 is provided with a brake groove 45 and a toothed groove 46. The upper end of the bracket 10 is provided with a drive box 43, and the middle of the drive box 43 is provided with a through hole 44 that matches the adjusting column 41. The outer side of the drive box 43 is provided with a brake cylinder 47 and an adjusting motor 413. The output end of the brake cylinder 47 is connected to a pressure sensor 48, a pressing plate 49 and a brake block 410. The output end of the adjusting motor 413 is connected to a rotating shaft 414, and a gear 415 is provided on the outer side of the rotating shaft 414.

[0028] After adopting the above technical solution, since the adjustment component 40 is set at the connection between the support 10 and the furrow opener 30, when the furrow opener 30 needs to adjust the furrowing depth, the controller controls the adjustment component 40 to raise and lower the furrow opener 30 along the inside of the support 10. This solves the problem that when the furrowing depth needs to be adjusted according to agronomic requirements such as soil moisture and crop variety, it is necessary to stop the machine and manually loosen the bolts for mechanical height adjustment, which is time-consuming and labor-intensive. Frequent start-ups and shutdowns of the equipment reduce operating efficiency and affect the sowing progress. Manual adjustment is prone to errors and can easily cause uneven sowing depth, affecting the uniformity of seedling emergence.

[0029] It should be noted that when the trencher 30 needs height adjustment, the controller controls the output of the adjusting motor 413 to drive the rotating shaft 414 to rotate, which in turn drives the gear 415 to rotate. This causes the gear 415 to mesh along the inside of the tooth groove 46, driving the adjusting column 41 to rise along the inside of the through hole 44. At the same time, the trencher 30 is also raised. When it rises to a suitable height, the controller controls the brake cylinder 47, causing the output of the brake cylinder 47 to move the pressure sensor 48, the extrusion plate 49, and the brake block 410. This causes the brake block 410 to contact and press against the brake groove 45, while simultaneously driving the auxiliary slider 411 to slide along the inside of the auxiliary slide groove 412. The pressure sensor 48 detects the clamping force, and when the set value is reached, it feeds back to the controller, which then controls the output of the brake cylinder 47 to stop clamping, thereby positioning the adjusting column 41 and further positioning the trencher 30, thus completing the height adjustment action of the trencher 30.

[0030] In an optional embodiment, the traction frame 20 and the support 10 are connected by bolts. There are two sets of walking wheels 50, which are symmetrically distributed. The two sets of walking wheels 50 are connected by a linkage rod 60. A bearing seat is provided at the connection between the linkage rod 60 and the support 10. As the walking wheels 50 rotate and drive the support 10 to move, the linkage rod 60 and the seeding tray 70 are driven to rotate. This causes the seeding claws on the outside of the seeding tray 70 to feed the seeds inside the seed storage box 80 into the seeding hole 90. At the same time, multiple sets of seeding claws can quantitatively grasp the seeds, thereby quantitatively sowing the seeds.

[0031] In an optional embodiment, the seeding tray 70 and the linkage rod 60 are fixedly connected. A rotating hole adapted to the seeding tray 70 is provided on one side of the seed storage box 80. The seeding hole 90 is connected to the seed storage box 80 to facilitate the grasping of seeds for planting. At the same time, the seeds inside the seed storage box 80 can be smoothly slid down along the seeding hole 90 for sowing.

[0032] In an optional embodiment, the adjusting column 41 and the trencher 30 are fixedly connected, and the adjusting column 41 is a column structure with a flat rectangular structure, so that it can be raised and lowered along the inside of the through hole 44, thereby preventing the adjusting column 41 and the trencher 30 from rotating or shifting position during the raising and lowering process, and ensuring that the trenching angle of the trencher 30 does not change.

[0033] In an optional embodiment, the through hole 44 extends through the middle of the drive box 43 and the bracket 10, and the through hole 44 is connected to the interior of the drive box 43, so as to facilitate the adjustment column 41 to move up and down.

[0034] In one optional embodiment, the brake groove 45 is a strip-shaped rectangular structure, and the toothed grooves 46 are evenly distributed on the outside of the adjusting column 41. The toothed grooves 46 mesh with the gear 415. The rotating shaft 414 can be rotated by adjusting the output end of the motor 413, which in turn drives the gear 415 to mesh with the toothed grooves 46, thereby raising and lowering the adjusting column 41.

[0035] It should be noted that the adjusting motor 413 is a self-locking motor, which will automatically lock when the output end stops running, ensuring that the gear 415 can stay inside the tooth groove 46, and further positioning the adjusting column 41.

[0036] In an optional embodiment, the output end of the brake cylinder 47 is fixedly connected to the pressure sensor 48, the pressure sensor 48 is fixedly connected to the extrusion plate 49, the extrusion plate 49 is fixedly connected to the brake block 410, and the brake block 410 is adapted to the brake groove 45. The output end of the brake cylinder 47 can drive the pressure sensor 48, the extrusion plate 49, and the brake block 410 to move, so that the brake block 410 contacts and is pressed against the brake groove 45, thereby braking and limiting the adjustment column 41 for positioning.

[0037] In one optional embodiment, two sets of auxiliary sliders 411 are fixedly connected to the outer side of the extrusion plate 49, and the drive box 43 has an auxiliary slide groove 412 that matches the auxiliary sliders 411 inside, which can ensure stability during the movement of the extrusion plate 49.

[0038] In an optional embodiment, the adjusting motor 413 is connected to the drive box 43 by bolts, the output end of the adjusting motor 413 is fixedly connected to the rotating shaft 414, and the rotating shaft 414 is fixedly connected to the gear 415. During the rotation of the rotating shaft 414, the gear 415 can be driven to rotate, and the gear 415 meshes with the inside of the tooth groove 46, thereby further raising and lowering the adjusting column 41.
