Description

Technical Field

[0001] This invention relates to the field of on-demand playback devices, specifically to a simple on-demand playback device for highland barley plots. Background Technology

[0002] Barley, a cereal crop belonging to the genus Hordeum in the family Poaceae, is also known as naked barley, hulled barley, or rice barley because its inner and outer husks are separated, exposing the grains. Barley is mainly produced in Tibet, Qinghai, Sichuan, and Yunnan provinces of China. It is a staple food for the Tibetan people and has extensive medicinal and nutritional value, leading to its widespread cultivation.

[0003] Seeders are widely used agricultural machines used for intercropping, fertilizing, weeding, and ditching in fields, offering multiple functions. Barley seeders are planting machines that sow barley seeds. Good barley seeders are widely used due to their advantages such as consistent seed depth, stable row spacing, good soil covering, and high efficiency. However, some existing seeders lack fertilization capabilities, requiring post-sowing fertilization, which consumes a lot of labor. Some seeders that can fertilize tend to mix fertilizer with the seeds, leading to seed burn, low germination rates, and reduced yields. Chinese invention patent application number 202122929418.9 discloses a precision seeding positioning device for field experimental plots. A controller can control the movement of the first, second, and third electric telescopic rods, thereby adjusting the spacing of the seed cylinders according to different sowing intervals. While its structure is simple, easy to operate, and highly automated, this device cannot fertilize simultaneously with sowing, and post-sowing soil covering is time-consuming and labor-intensive. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the present invention provides a simple barley plot sowing device, which solves the problems that existing barley plot sowing devices cannot fertilize at the same time as sowing and require covering with soil after sowing.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A simple barley planting device is provided, including a vehicle body. Two sets of rectangular slots are longitudinally spaced at the lower end of the vehicle body. A movable block is slidably connected in the rectangular slot. A first electric telescopic rod is connected to the lower end of the movable block. A first sleeve is connected to the telescopic end of the first electric telescopic rod. A second sleeve is coaxially arranged in the first sleeve. A soil covering component is arranged between the first sleeve and the second sleeve. The extension and retraction of the soil covering component realizes the opening or closing of the second sleeve.

[0007] The first sleeve has cavities on both sides of its exterior, which are used for sowing and fertilizing barley, respectively. The lower end of the cavities has a discharge port. A second electric telescopic rod is vertically fixed inside the cavities. The telescopic end of the second electric telescopic rod is connected to a plug that matches the discharge port. The vehicle body is equipped with a seed box and a fertilizer box, which are connected to the two cavities through conveying pipes.

[0008] Furthermore, the soil covering assembly includes two sets of symmetrically arranged telescopic mechanisms. Each telescopic mechanism includes a third electric telescopic rod, the upper end of which is fixed to the first sleeve. The telescopic end of the third electric telescopic rod is hinged with a baffle. When the telescopic end of the third electric telescopic rod is extended to its maximum state, the two baffles of the two sets of telescopic mechanisms abut against each other, thereby closing the second sleeve.

[0009] Furthermore, a guide block is provided on the inner wall of the first sleeve. The guide block is located below the third electric telescopic rod. The guide block is an inclined block with its inclined surface facing upward toward the second sleeve, in order to guide the movement of the baffle.

[0010] Furthermore, the plug is spherical. When the extension end of the second electric telescopic rod is retracted to its minimum state, the center of the spherical plug coincides with the center of the discharge port. When the extension end of the second electric telescopic rod is extended to its maximum state, the spherical plug completely detaches from the receiving cavity, and the seeds or fertilizer in the receiving cavity fall out.

[0011] Furthermore, the lower end of the plug is provided with a tapered tip.

[0012] Furthermore, a fourth electric telescopic rod is laterally connected to the moving block.

[0013] Furthermore, the vehicle body is provided with a support assembly, which includes two sets of bracket slots that are longitudinally spaced apart on the vehicle body. The brackets are rotatably connected in the two sets of bracket slots, and the lower ends of the brackets are connected to the legs. The vehicle body is also provided with a locking assembly that cooperates with the brackets.

[0014] Furthermore, the locking assembly includes a first magnet disposed in a bracket groove, and a second magnet that engages with the first magnet is disposed on the bracket.

[0015] Furthermore, the vehicle body is equipped with handles, which are fitted with non-slip rubber sleeves.

[0016] Furthermore, rollers are installed under the vehicle body.

[0017] The beneficial effects of this invention are as follows:

[0018] The device of this invention has a simple structure and integrated functions. It can fertilize at the same time as sowing barley, separating the seeds and fertilizers to avoid burning the seeds. After sowing, it can cover the barley seeds and fertilizers with soil, saving time and effort. Attached Figure Description

[0023] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims.

[0024] Example

[0025] Reference Figures 1-3A simple barley planting device includes a vehicle body 1 with a handle 23 and a non-slip rubber sleeve. Rollers 24 are located at the bottom of the vehicle body 1. The vehicle body 1 can be moved by pushing the handle 23. Two sets of rectangular grooves 2 are longitudinally spaced at the lower end of the vehicle body 1. Moving blocks 3 are slidably connected within the rectangular grooves 2, and a fourth electric telescopic rod 17 is laterally connected to the moving blocks 3. A first electric telescopic rod 4 is connected to the lower end of the moving blocks 3. A first sleeve 5 is connected to the telescopic end of the first electric telescopic rod 4. A second sleeve 6 is coaxially arranged within the first sleeve 5. A soil covering assembly is arranged between the first sleeve 5 and the second sleeve 6. The telescopic movement of the soil covering assembly opens or closes the second sleeve 6. Specifically, the soil covering assembly includes two symmetrically arranged telescopic mechanisms. Each telescopic mechanism includes a third electric telescopic rod 13. The upper end of the third electric telescopic rod 13 is fixed to the first sleeve 5, and a baffle 14 is hinged to the telescopic end of the third electric telescopic rod 13. As a preferred embodiment, a guide block 15 is provided on the inner wall of the first sleeve 5. The guide block 15 is located below the third electric telescopic rod 13. The guide block 15 is an inclined block with its inclined surface facing upward toward the second sleeve 6, in order to guide the movement of the baffle 14.

[0026] When the telescopic end of the third electric telescopic rod 13 extends, the baffle 14 moves toward the guide block 15. When the baffle 14 contacts the inclined surface of the guide block 15, the baffle 14 rotates relative to the movable end of the third electric telescopic rod 13. When the telescopic end of the third electric telescopic rod 13 is extended to its maximum state, the two baffles 14 of the two sets of telescopic mechanisms abut against each other, thereby closing the second sleeve 6.

[0027] The first sleeve 5 has receiving cavities 7 on both sides of its exterior, used for sowing and fertilizing barley, respectively. A discharge port 8 is located at the lower end of each receiving cavity 7. A second electric telescopic rod 9 is vertically fixed inside each receiving cavity 7, and a plug 10 that cooperates with the discharge port 8 is connected to the telescopic end of the second electric telescopic rod 9. A seed box 11 and a fertilizer box 12 are installed on the vehicle body 1, and the seed box 11 and fertilizer box 12 are connected to the two receiving cavities 7 respectively via conveying pipes. Specifically, the plug 10 is spherical. When the telescopic end of the second electric telescopic rod 9 is retracted to its minimum state, the center of the spherical plug 10 coincides with the center of the discharge port 8; when the telescopic end of the second electric telescopic rod 9 is extended to its maximum state, the spherical plug 10 completely detaches from the receiving cavity 7, and the seeds or fertilizer inside the receiving cavity 7 fall out. Preferably, the lower end of the plug 10 has a conical tip 16.

[0028] In this embodiment of the invention, the first electric telescopic rod 4, the second electric telescopic rod 9, the third electric telescopic rod 13, and the fourth electric telescopic rod 17 are all connected to a controller. When using this device, barley seeds and fertilizer are respectively placed in the seed box 11 and the fertilizer box 12. The vehicle body 1 can be moved by pushing the handle 23. Adjusting the left and right movement of the fourth electric telescopic rod 17 via the controller can move the moving block 3 left and right, thereby adjusting the sowing row spacing and improving the applicability of the device. Controlling the extension of the first electric telescopic rod 4 via the controller can cause the first sleeve 5 and the second sleeve 6 to insert into the ground, allowing soil to enter the second sleeve 6. Controlling the extension of the third electric telescopic rod 13 via the controller can cause the two baffles 14 to abut, sealing the second sleeve 6 and enclosing the soil within it. Controlling the extension of the second electric telescopic rod 9 via the controller allows the seeds and fertilizer in the left and right receiving cavities 7 to fall out. Finally, the controller controls the retraction of the first electric telescopic rod 4, the second electric telescopic rod 9, and the third electric telescopic rod 13. The retraction of the third electric telescopic rod 13 will release the abutment of the two baffles 14, causing the soil in the second sleeve 6 to be spilled out, covering the barley seeds and fertilizer.

[0029] To facilitate users in securing the vehicle body 1 during rest or when pausing work, the present invention also includes the following design.

[0030] The vehicle body 1 is equipped with a support assembly, which includes two sets of bracket slots 18 longitudinally spaced on the vehicle body 1. A bracket 19 is rotatably connected within the two sets of bracket slots 18, and a support leg 20 is connected to the lower end of the bracket 19. The vehicle body 1 also has a locking assembly that cooperates with the bracket 19. Specifically, the locking assembly includes a first magnet 21 disposed within a bracket slot 12, and a second magnet 22 disposed on the bracket 19 that cooperates with the first magnet 21. When the user is resting or pausing work, the bracket 19 can be removed from the bracket slot 18 and placed on the ground to prevent the vehicle body 1 from tipping over, facilitating future use. When not in use, the first magnet 21 and the second magnet 22 attract the bracket 19 together, allowing the vehicle body 1 to be moved.

[0031] The device of this invention has a simple structure and integrated functions. It can fertilize at the same time as sowing barley, separating the seeds and fertilizers to avoid burning the seeds. After sowing, it can cover the barley seeds and fertilizers with soil, saving time and effort.
