Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-9This utility model provides a technical solution: a precision air-suction furrowing seeder, including a frame 1, with a furrowing roller 2 rotatably connected between the front ends of the left and right inner walls of the frame 1. Furrowing teeth 4 are integrally arranged evenly along the circumferential direction on the outer side of the furrowing roller 2. A connecting rod 5 is welded and fixed between the middle of the left and right inner walls of the frame 1. An installation groove 6 is linearly arranged from left to right on the rear side of the connecting rod 5, and a seeding tube 7 is welded and fixed within the installation groove 6. A seeding roller 10 is rotatably connected between the rear ends of the left and right inner walls of the frame 1. Adsorption holes 11, with a diameter smaller than the outer diameter of the seed and corresponding to the seeding tube 7, are evenly distributed along the circumferential direction on the outer side of the seeding roller 10. A fan 14 for negative pressure adsorption is connected to the outer side of the seeding roller 10. Specifically... The blowers 14 can be configured as two symmetrical ones to provide more sufficient negative pressure suction. An L-shaped fixing frame 15 is welded and fixed to the rear wall of the frame 1. The horizontal end of the L-shaped fixing frame 15 is provided with a storage groove 16 for storing seeds, which corresponds to the bottom of the sowing roller 10. A vibration structure 18 is provided at the vertical end of the L-shaped fixing frame 15. A synchronous drive assembly 19 is provided on the frame 1. A soil covering structure 17 is provided on the rear side of the frame 1. A soil leveling structure 23 is provided on the front side of the frame 1. Specifically, the soil leveling structure 23 is rotatably connected to the front end of the frame 1 through a hinged bracket. The bottom of the soil leveling structure 23 is provided with arc-shaped combing grooves arranged linearly. The soil leveling structure 23 plays the role of leveling the soil before ditching.

[0025] Furthermore, such as Figure 4 As shown, the rear side of the seeding tube 7 is provided with a feed inlet 8 corresponding to the adsorption hole 11. The bottom of the feed inlet 8 is integrally provided with an elastic scraper 9 that is tilted backward and elastically contacts the upper part of the front side of the seeding drum 10. The elastic scraper 9 can elastically scrape the seeds adsorbed on the adsorption hole 11 on the upper part of the front side of the seeding drum 10, ensuring that they smoothly enter the seeding tube 7 through the feed inlet 8 to complete the seeding.

[0026] Furthermore, such as Figure 7 As shown, the soil covering structure 17 includes a leveling shovel 171 and a brush 172. The leveling shovel 171 is welded and fixed to the rear side of the frame 1, and the brush 172 is glued and fixed to the bottom of the leveling shovel 171. The leveling shovel 171 and the brush 172 contact the ground to facilitate leveling the soil covering after sowing.

[0027] Furthermore, such as Figure 2 As shown, the left and right ends of the grooving roller 2 are respectively welded and fixed with rotating shaft 3, and the outer ends of the two rotating shafts 3 are respectively rotatably connected to the front end of the left and right inner walls of the frame 1 through bearings.

[0028] Furthermore, it also includes a vibrating structure 18, such as Figure 8As shown, the vibration structure 18 includes a vibration motor 181 and a vibration rod 182. The vibration motor 181 is fixedly connected to the front side of the upper vertical end of the L-shaped fixing frame 15 by bolts and nuts. The bottom of the vibration output end of the vibration motor 181 is welded and fixed to the vibration rod 182 through a connecting bracket. Specifically, the bottom of the vibration rod 182 contacts the storage groove 16. During the sowing and seed suction process, when seeds are squeezed together and some seeds are sucked away, creating gaps, the vibration motor 181 drives the vibration rod 182 to vibrate, quickly filling the gaps and ensuring that the seeds are in a relaxed state, which facilitates better suction and can help improve the air suction seed loading rate.

[0029] Furthermore, such as Figure 5 As shown, a rotating shaft 12 is welded and fixed to one end of the sowing drum 10. The outer end of the rotating shaft 12 is rotatably connected to the inner wall of the frame 1 through a bearing. The other end of the sowing drum 10 is rotatably connected to a connecting pipe 13 that communicates with its inner cavity through a bearing. The outer end of the connecting pipe 13 is welded and fixed to the inner wall of the frame 1. The fan 14 is fixed to the side of the frame 1 near the connecting pipe 13 by bolts and nuts. The air inlet of the fan 14 is correspondingly connected to the inner cavity of the connecting pipe 13. Through the air suction adsorption of the fan 14, the adsorption holes 11 on the rotating sowing drum 10 can adsorb the seeds with sowing.

[0030] Furthermore, such as Figure 9 As shown, the synchronous drive assembly 19 includes a second motor 191, a driving sprocket 192, a first chain 193, a first driven sprocket 194, a second chain 195, and a second driven sprocket 196. An inverted U-shaped fixing frame 20 is linearly arranged from left to right between the upper surface of the front end of the frame 1 and the upper surface of the connecting rod 5, covering the grooving roller 2 and the grooving toothed plate 4. Specifically, the bottom ends of the two arms of the inverted U-shaped fixing frame 20 are welded and fixed to the upper surface of the front end of the frame 1 and the upper surface of the connecting rod 5, respectively. One side of the inverted U-shaped fixing frame 20 is fixedly connected to the second motor 191 by bolts and nuts. The output shaft of the second motor 191 is fixedly connected to one side of the driving sprocket 192, and the driven sprocket 194 is fixed... On the outer side of the rotating shaft 13 located on the same side as the fan 14, a chain 193 is provided on the outer side of the driving sprocket 192 and the driven sprocket 194. A driven sprocket 196 is fixed on the outer side of the other rotating shaft 13 and the rotating shaft 12. A chain 195 is provided on the outer side of the two driven sprockets 196. The rotation of the driving sprocket 192 driven by the motor 191 drives the rotation of the chain 193 and the driven sprocket 194, which can drive the ditching roller 2, the rotating shaft 13 and the ditching toothed plate 4 to rotate and move to perform ditching operation. At the same time, the rotation of the chain 195 and the driven sprocket 196 can drive the seeding roller 10 to rotate synchronously to perform seeding and feeding operation.

[0031] Furthermore, such as Figure 1As shown, the generator 21, controller 22, and seed storage box are sequentially fixed to the inverted U-shaped mounting bracket 20 by bolts and nuts. Specifically, the fan 14, vibration motor 181, motor 191, generator 21, and controller 22 are electrically connected to each other, and all of them can use conventional equipment commonly used in the prior art. For example, generator 21 can be a 3 kW variable frequency gasoline generator; motor 191 can be a micro motor; fan 14 can be a 350 kW brushless dust collector; controller 22 can be a TC5520 microcontroller. All of the above equipment can use conventional equipment in the prior art, and their operation and control principles are existing mature technologies, so their principles will not be further described here.

[0032] In addition, such as Figure 1 As shown, handrails are provided at both ends of the rear side of the frame 1. A button control switch corresponding to the controller 22 is installed on the side of one of the handrails. A soil compaction roller is also provided at the rear end of the frame 1 to assist in supporting walking and compacting soil after covering. Its operation and control principle is also a mature existing technology, which will not be described in detail here.

[0033] When using:

[0034] The generator 21 generates electricity, and the controller 22 controls the fan 14 to start and drive the seeding drum 10 to perform air suction and material feeding. The motor 182 drives the pressing roller 2, the rotating shaft 3 and the pressing toothed plate 4 to rotate and move, and simultaneously drives the seeding drum 10 to rotate and absorb the material. The seeds are then sown through the seeding pipe 7. Finally, the soil is covered by the dragging and moving covering chain 23 to complete the operation.

[0035] Specifically, in actual operation, the air suction pressure furrow precision seeder of this invention can increase efficiency by 20 times and save 30% of seeds.

[0036] The same method of furrowing and sowing requires 5 people for manual operation, which is inefficient: 2 people use furrow pressers to press the furrows, 2 people sow the seeds from behind, and 1 person covers the soil from behind. The maximum amount of soil covered per day is 200 zhang.

[0037] The seeder of this utility model only requires one person to operate and can complete furrow pressing, sowing, and covering at the same time: it can easily sow 2,000 zhang (ginseng sowing is calculated by zhang, one zhang is 1.5-1.7 meters wide and 3.3 meters long) per day. Four people can sow about 1.5 mu per day.

[0038] Therefore, it can be seen that the efficiency of the seeder of this utility model is 10 times that of manual labor, only requires one person, saving 4 people, and can well control the seeding quantity and row spacing accuracy, avoiding the waste of seeds by manual sowing, ensuring the row spacing of furrows, and avoiding the waste of land resources.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
