[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] As shown in Figures 1-3, a simulated air suction vegetable seeding and sowing machine includes an exhaust box 1, an exhaust port 2 communicating with the inner cavity of the exhaust box 1 is opened in the middle of the rear end of the exhaust box 1, and mounting ports 3 communicating with the inner cavity are opened in the middle of the left end and the middle of the right end of the exhaust box 1. The inner cavities of the two mounting ports 3 are fixedly installed with sowing components 4. Through the set sowing components 4, when the device is used for sowing, with the assistance of the sowing components 4, the spacing of seeds during sowing can be kept consistent, and the exhaust box 1 is fixedly installed with a soil-breaking component 5 on the left side of the middle front end and the right side of the middle front end. The exhaust port 2 is fixedly installed with a soil-returning component 6 on the left side of the rear end and the right side of the rear end. Through the set soil-breaking component 5 and soil-returning component 6, before the sowing component 4 sows, the soil-returning component 6 can break the soil, and then after the sowing component 4 sows the seeds into the soil, the soil-returning component 6 can perform soil-returning.

[0026] It should be noted that the sowing component 4, soil-breaking component 5 and soil-returning component 6 in this device are the core structures of an imitation air-suction vegetable seedling seeder. In order to facilitate use during implementation, the device can be installed on a tractor or other driving equipment based on this solution, thereby further facilitating the use of this device.

[0027] In order to achieve the purpose of controlling the sowing spacing during sowing, referring to Figures 1-4, the sowing components 4 include a negative pressure machine 41 fixedly connected to the inner cavity of the mounting port 3, the output end of the negative pressure machine 41 is fixedly connected to a sealing tube 42, the left end of the sealing tube 42 is fixedly connected to a baffle 43, and the middle part of the right side wall of the inner surface of the baffle 43 is rotatably connected to a feed tray 44, and the left side wall of the inner surface of the baffle 43 is provided with a plurality of suction holes 45 in an annular array connected to the right end of the baffle 43, and the plurality of suction holes 45 are respectively located between the gaps of the feed tray 44, and a storage box 48 is fixedly connected to the lower part of the inner surface of the baffle 43, and a discharge plate 49 is fixedly connected to the right side of the front end of the storage box 48, and a partition 46 is fixedly connected to the front right end of the storage box 48, and the lower right end of the discharge plate 49 is fixedly connected to the left end of the baffle 43, and the middle part of the left end of the feed tray 44 is fixedly connected to a drive rod 47 that passes through the partition 46 and extends to the outside of the storage box 48.

[0028] Furthermore, the outer diameter formed by the circular arrangement of the plurality of suction holes 45 is smaller than the inner diameter of the sealing tube 42 .

[0029] Before using the device, the output end of the driving rod 47 can be connected to the output end of the tractor or other driving device through the connecting structure in the prior art, and the driving rod 47 is powered by the connected equipment. The specific connection method is the conventional connection method in the prior art, and then the negative pressure machines 41 on both sides are started, so that the negative pressure machines 41 on both sides respectively perform negative pressure treatment on the inner cavity of the sealed tube 42 fixedly connected thereto. When the inner cavity of the sealed tube 42 is in a negative pressure state, it can be seen from the above that the outer diameter formed by the circular arrangement of the plurality of suction holes 45 is smaller than the inner diameter of the sealed tube 42. Therefore, the plurality of suction holes 45 connected thereto can form suction to the inner cavity of the sealed tube 42, and the air inhaled by the negative pressure machine 41 can be discharged from the exhaust port 2 opened at the rear end of the exhaust box 1. At the same time, the driving rod 47 drives the feeding tray 44 to rotate. When the feeding tray 44 is fed, the feeding tray 44 is rotated. When the material tray 44 rotates, the seeds placed in the material storage box 48 can be sucked into the gap of the feed tray 44 under the suction force of the several suction holes 45. The gap between the partition 46 and the feed tray 44 is small, so the seeds can be directly sucked into the gap of the feed tray 44, and then the seeds are transported to the front side of the material storage box 48 through the gap of the feed tray 44 in turn. When the seeds pass the front side of the material storage box 48, since there are no suction holes 45 on the surface of the baffle 43 on the front side of the material storage box 48, the suction force disappears, and then the seeds fall along the track between the baffle 43 and the discharge plate 49. The gap of the feed tray 44 is distributed in a circular array, which is the same as the distribution position of the several suction holes 45. Therefore, the frequency of sowing seeds is the same, which reduces the situation where multiple seeds are sown at the same time due to different sowing efficiencies, thereby improving the sowing efficiency.

[0030] The negative pressure machine 41 mentioned above is a prior art that uses the negative pressure generated by the machine to inhale and transport the gas. The specific working principle is as follows:

[0031] The suction and discharge of gas is achieved by changing the volume. When the vacuum pump 41 is running, it creates an area lower than the ambient atmospheric pressure, which is called negative pressure. This negative pressure causes the surrounding gas to enter the working area of ​​the pump and be transported to the desired location.

[0032] Therefore, the negative pressure machine 41 is of conventional design in the prior art and will not be described in detail in this solution.

[0033] In order to achieve the purpose of breaking the soil before sowing and returning the soil after sowing, referring to Figures 1 and 5-6, the soil-breaking component 5 includes two symmetrically distributed fixed blocks 51 fixedly connected to the middle part of the front end of the exhaust box 1, and the front ends of the two fixed blocks 51 are fixedly connected to the mounting plates 52, and the front ends of the two mounting plates 52 away from each other are fixedly connected to the soil-breaking plates 53.

[0034] Furthermore, the backfill assembly 6 includes two L-shaped plates 61 fixedly connected to the left and right sides of the rear end of the exhaust box 1, and the front ends of the two L-shaped plates 61 are fixedly connected to the sides away from each other with backfill plates 62.

[0035] Furthermore, the earth-breaking plate 53 is arranged in a triangular shape, and the two earth-returning plates 62 are arranged in an eight-shaped shape. The two earth-breaking plates 53 are respectively arranged in parallel with the two earth-returning plates 62 in front and back directions.

[0036] When the device is driven forward as a whole by a tractor or other driving device, before sowing, since the soil-breaking component 5 is installed at the front end of the exhaust box 1, and as can be seen from the above, the soil-breaking plates 53 are arranged in a triangular shape, when the device moves forward, the soil-breaking plates 53 on both sides can break the soil passing by, and the broken soil will be pushed to both sides. Then, under the action of the sowing component 4, the seeds can be sown into the soil in sequence;

[0037] After the seeds are sown into the soil, since the backfilling component 6 is installed on the rear side of the sowing component 4, and as can be seen from the above, the two breaking plates 53 are respectively arranged in parallel with the two backfilling plates 62, and the two backfilling plates 62 are both arranged in an eight-shaped shape, the backfilling plates 62 can backfill the soil when passing through the soil broken by the breaking plates 53, thereby completing the backfilling work. This solution uses the breaking components 5 and backfilling components 6 to eliminate the need for manual soil breaking and backfilling before and after sowing, thereby reducing labor and improving sowing efficiency.

[0038] It should be noted that the specific installation method, circuit connection method and control method of the negative pressure machine 41 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0039] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention.
