[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An agricultural planting device includes a planting frame. Two L-shaped fixing frames are fixedly connected to the upper end of the planting frame. The relatively close ends of the two L-shaped fixing frames are fixedly connected to the front and rear ends of a planting box, respectively. Two discharge pipes are fixedly connected to the lower end of the planting box. The lower ends of the two discharge pipes are slidably connected to the upper side of an adjusting planting component.

Two electric push rods are fixedly installed on the left side of the planting frame, and the lower ends of the two electric push rods are fixedly connected to a mounting frame. Two furrowing plows are fixedly connected to the mounting frame.

[0008] The two furrowing plows correspond to the two seeding tubes respectively. The seeding frame is slidably connected to a number of limiting slide bars through a number of limiting holes opened inside its left side. The lower ends of the limiting slide bars are all fixedly connected to the mounting frame. A traction connecting frame is fixedly connected to the left end of the seeding frame.

[0009] The adjustable seeding component includes an installation frame, the left and right sides of which are fixedly connected to the left and right ends of two circular shells respectively. The two circular shells are slidably connected to the lower ends of two discharge pipes respectively through through grooves opened inside their upper right sides.

[0010] The lower ends of the two circular shells are movably connected to the upper sides of the two rotating rods, and the upper ends of the two rotating rods are fixedly connected to the two circular seeding plates.

[0011] The upper and lower ends of the two circular seeding plates are infinitely close to but do not contact the upper and lower sides of the two circular shells. The interior of each of the two circular seeding plates is provided with a seeding trough one and a seeding trough two, and the two seeding troughs two are respectively corresponding to the two discharge pipes.

[0012] The upper ends of the two circular seeding plates are infinitely close to but not in contact with the lower ends of the two discharge pipes. Each of the two rotating rods is movably connected to an L-shaped plate, and the upper ends of the two L-shaped plates are fixedly connected to the lower ends of the two circular shells.

[0013] The lower ends of the two rotating rods are fixedly connected to worm gears, and the two worm gears mesh with two hollow worms respectively. The two hollow worms are fixedly connected to the rotating rod, and the rear end of the rotating rod is fixedly connected to the motor output shaft.

[0018] This invention, through the coordination of a motor, a second rotating rod, a second hollow worm gear, a worm wheel, and a first rotating rod, enables a circular seeding plate to rotate inside a corresponding circular housing. During this rotation, the seeding grooves (either one or two) on the seeding plate guide seeds from inside the seeding box through a guide housing and seeding pipe into the prepared seeding furrows, ensuring uniformity in the seeding process. The electric push rod, a support slider, a mounting frame, and a mounting housing further enable the two circular seeding plates to move left and right, adjusting the position of the seeding grooves (one and two) on the circular seeding plates relative to the corresponding discharge pipes. This allows for adjustment of the seeding quantity per batch during subsequent seeding processes, effectively avoiding the inconvenience of adjusting the seeding quantity in traditional seeding equipment.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, an agricultural planting sowing device includes a sowing frame 1. Two L-shaped fixing frames 8 are fixedly connected to the upper end of the sowing frame 1. The relatively close ends of the two L-shaped fixing frames 8 are fixedly connected to the front and rear ends of a sowing box 9, respectively. Two discharge pipes 11 are fixedly connected to the lower end of the sowing box 9. The lower ends of both discharge pipes 11 are slidably connected to the upper side of an adjusting sowing component 7. Two sowing tubes 10 are fixedly connected to the lower side of the adjusting sowing component 7. The lower end of the adjusting sowing component 7 is fixedly connected to the upper end of the sowing frame 1. Two electric push rods 6 are fixedly installed on the left side of the sowing frame 1. The lower ends of both electric push rods 6 are connected to a mounting frame. 5. Fixed connection: Two furrowing plows 3 are fixedly connected to the mounting frame 5. By starting the electric push rod 6, the mounting frame 5 is moved downward, thereby achieving the effect of adjusting the position and height of the furrowing plows 3 during the sowing process, which facilitates the adjustment of the sowing depth. Then, with the cooperation of the set adjustable sowing component 7, the discharge pipe 11 and the sowing pipe 10, the crop seeds inside the sowing box 9 can be sown into the cultivated sowing furrow, thereby realizing the sowing process of crop seeds. The set adjustable sowing component 7 can also adjust the amount of seeds sown at one time according to the sowing needs during the sowing process.

[0028] Furthermore, the two furrowing plows 3 correspond to the two seeding tubes 10 respectively. The seeding frame 1 is slidably connected to several limiting slide bars 2 through several limiting holes opened inside its left side. The lower ends of the limiting slide bars 2 are all fixedly connected to the mounting frame 5. The left end of the seeding frame 1 is fixedly connected to the traction connecting frame 4. The combination of the limiting slide bars 2 and the seeding frame 1 can increase the stability of the mounting frame 5 during use.

[0029] Furthermore, the adjusting seeding assembly 7 includes a mounting frame 71. The left and right sides of the mounting frame 71 are fixedly connected to the left and right ends of two circular housings 72, respectively. Each circular housing 72 is slidably connected to the lower ends of two discharge pipes 11 via a through groove on its upper right side. The lower ends of the two circular housings 72 are movably connected to the upper sides of two rotating rods 76, respectively. The upper ends of the two rotating rods 76 are fixedly connected to two circular seeding plates 74, respectively. The upper and lower ends of the two circular seeding plates 74 are infinitely close to but not in contact with the upper and lower sides of the interior of the two circular housings 72. Each circular seeding plate 74 has a seeding groove 78 and a seeding groove 79, respectively. The two seeding grooves 79 correspond to the two discharge pipes 11, respectively. The upper ends of the two circular seeding plates 74 are respectively connected to the lower ends of the two discharge pipes 11. The lower ends are infinitely close but do not touch. Both rotating rods 76 are movably connected to L-shaped plates 77. The upper ends of the two L-shaped plates 77 are fixedly connected to the lower ends of the two circular shells 72 respectively. The lower ends of the two rotating rods 76 are fixedly connected to worm gears 75. The rotation of the worm gears 75 drives the rotating rods 76 to rotate, thereby driving the circular seeding plate 74 to rotate. During the rotation of the circular seeding plate 74, when the seeding trough 79 overlaps with the discharge pipe 11, the seeds inside the seeding box 9 will fall quantitatively into the seeding trough 79. Then, when the seeding trough rotates to overlap with the through groove opened on the lower left side of the circular shell 72, the seeds inside will fall into the opened seeding furrow through the guide shell 73 and the seeding pipe 10, thereby realizing the sowing of seeds and ensuring the uniformity of the sowing process.

[0030] Two worm gears 75 mesh with two hollow worms 716, which are fixedly connected to a rotating rod 715. The rear end of the rotating rod 715 is fixedly connected to the output shaft of a motor 713. The motor 713 is fixedly mounted on the lower end of the mounting frame 71 via a frame mounted on it. A support plate 717 is movably connected to the front end of the rotating rod 715, and the upper end of the support plate 717 is fixedly connected to the mounting frame 71. Two circular sleeves 72 are fixedly connected to two guide housings 73 via another through groove on their lower left side. The lower ends of the two guide housings 73 are fixedly connected to the upper ends of the two seeding tubes 10. Support sliders 711 are fixedly connected to both the front and rear ends of the mounting frame 71. The two support sliders 711 are slidably connected to two fixed rods 712. L-shaped fixing plates 710 are fixedly connected to both the left and right ends of the two fixed rods 712. The lower ends of the four L-shaped fixing plates 710 are all connected to the seeding vehicle. The frame 1 is fixedly connected, and electric push rods 714 are fixedly installed on the two L-shaped fixed plates 710 on the left side. The right ends of the two electric push rods 714 are fixedly connected to the two support sliders 711 respectively. The rotation of the output shaft of the motor 713 drives the rotating rod 715 to rotate, which, in conjunction with the hollow worm gear 716, drives the worm wheel 75 to rotate. By activating the two electric push rods 714, the mounting frame 71 is moved to the right by a certain distance. Then, under the action of the circular sleeve 72 and the circular seeding plate 74, the seeding trough 79 moves out from under the corresponding discharge pipe 11 until the seeding trough 78 moves to correspond with the discharge pipe 11. At this time, the single seeding amount can be adjusted during the seed sowing process. The cooperation of the support sliders 711, L-shaped fixed plates 710 and fixed rods 712 can limit the movement direction of the mounting frame 71.

[0031] The working principle of this utility model is as follows:

[0032] When using this device for sowing, first move the device to the designated location in the field and connect it to an agricultural tractor via the traction connection frame 4. Then, the agricultural tractor drives the device to move. During the movement, the furrow opener 3 can dig sowing furrows in the field. At this time, start the motor 713 to drive the rotating rod 715 to rotate. Then, under the action of the hollow worm 716 and the worm wheel 75, the rotating rod 76 can be driven to rotate. The rotation of the rotating rod 76 can drive the circular sowing plate 74 to rotate inside the corresponding circular casing 72. When the sowing trough 79 rotates to align with the discharge pipe 11, the seeds inside the sowing box 9 can fall into the sowing trough in a measured amount. In the second 79, as the circular seeding plate 74 rotates, when the second seeding trough 79 corresponds to the through groove opened inside the lower left side of the circular casing 72, the seeds stored inside can fall into the seeding furrow at the cultivated area through the guide casing 73 and the seeding pipe 10, thus completing the seed sowing process. When it is necessary to adjust the single seed sowing amount during the sowing process, the two electric push rods 714 are activated to drive the two support sliders 711 to move to the right a certain distance, which in turn drives the mounting frame 71 to move to the right a certain distance, so that the second seeding trough 79 on the circular rotating plate moves out from the lower side of the discharge pipe 11 until the first seeding trough 78 coincides with the discharge pipe 11, thus realizing the adjustment process of the single seed sowing amount during the sowing process.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
