Description

Technical Field

[0001] The invention relates to the technical field of multi-thread seedling planting devices, in particular to a process-based multi-thread seedling planting equipment for desertified land. Background Art

[0002] As populations continue to grow, demand for land increases. Increased human activity, coupled with climate change, has led to the expansion of natural deserts, the destruction of vegetation on sandy soils, and the resulting desertification. Traditional manual planting is still the primary method in many areas, which is labor-intensive and inefficient. The development of the corresponding seedling cultivation technology has also been slow, resulting in limited versatility and reliability of transplanting machinery and high costs for mechanized planting.

[0003] Existing transplanting machines have several significant drawbacks: Different soil types vary, making it difficult to achieve multi-purpose applications. For example, sandy soil is loose and breathable, but its ability to retain water and fertilizer is generally poor, making it difficult to guarantee seedling survival rates.

[0032] The spraying assembly includes a spraying mechanism and a spraying pipe 5. The spraying pipe 5 and the liquid storage box 4 are connected to each other. When the rebound opening nozzle assembly drives the seedling nozzle 3 to dig, the spraying mechanism will spray the pesticide in the spraying pipe 5;

[0033] The anti-clogging component includes a driving mechanism, a mobile scraping mechanism, and an airflow injection mechanism. The driving mechanism is used to drive the mobile scraping mechanism to move. The mobile scraping mechanism is used to scrape off the mud clogged at the liquid outlet end of the spraying pipe 5. The airflow injection mechanism is used to use airflow to spray and remove the mud at the liquid outlet end of the spraying pipe 5.

[0034] The pressurizing component includes a pressurizing box 6, an air compression mechanism and a connecting mechanism. The pressurizing box 6 is used to store compressed air, the air compression mechanism is used to compress air into the pressurizing box 6, and the connecting mechanism is used to connect the pressurizing box 6 to the spray pipe 5 or the driving mechanism.

[0035] The rebound opening mouth assembly includes a cylinder push rod 7, a seedling planting tube 8, a connecting rod 9, a bearing sleeve 10, a support leg 11 and a rolling bearing 12. The cylinder push rod 7 is connected to the bottom of the crawler mobile vehicle 1. The cylinder push rod 7 is used to drive the seedling planting tube 8 to move. The seedling planting tube 8 is connected to the seedling planting mouth 3 through a hinge, so the seedling carrying mouth can rotate around the hinge to realize the excavation of desertified land. The seedling planting mouth 3 is connected to the bearing sleeve 10 through the connecting rod 9. The bearing sleeve 10 is connected to the rolling bearing 12, and the rolling bearing 12 fits into the seedling planting tube 8.

[0036] In this embodiment, the liquid storage box 4 is fixedly connected to the outside of the seedling planting tube 8.

[0037] The spraying mechanism includes a jet pump 13 and an atomizer 14 . The jet pump 13 is arranged inside the liquid storage box 4 . The jet pump 13 is connected to the atomizer 14 through a spraying pipe 5 . The atomizer 14 is fixedly connected to the seedling nozzle 3 .

[0038] The driving mechanism includes a pneumatic push rod 15, a pneumatic intermittent valve 16 and a contraction spring 17. The pneumatic push rod 15 is a pneumatic push rod 15 driven by direct current. The pneumatic push rod 15 is arranged on the seedling planting nozzle 3. The telescopic end of the pneumatic push rod 15 is fixedly connected to the scraping block 19 of the mobile scraping mechanism. The pneumatic intermittent valve 16 is arranged on the pneumatic push rod 15. The pneumatic intermittent valve 16 controls the opening and closing of the valve according to the compressed air inside the pneumatic push rod 15 so that the pneumatic push rod 15 drives the scraping block 19 to achieve reciprocating motion. The contraction spring 17 is arranged inside the pneumatic push rod 15.

[0039] The mobile scraping mechanism includes a limit block 18 and a scraping block 19. The limit block 18 is fixedly connected to the seedling nozzle 3. The limit block 18 is used to limit the moving direction of the scraping block 19. The scraping block 19 is slidingly connected to the limit block 18. The telescopic end of the pneumatic push rod 15 is fixedly connected to the scraping block 19.

[0040] The airflow injection mechanism includes a pressure relief valve 20, which is arranged on one side of the scraping block 19. The pressure relief valve 20 is an electromagnetic valve. When in use, the opening of the pressure relief valve 20 is controlled to directly inject the compressed air in the pressurizing box 6 into the outlet of the atomizer 14, thereby cleaning the dirt or dust attached to the outlet of the atomizer 14.

[0041] The air compression mechanism includes a cylinder 21, a movable piston 22, a connecting rod 23 and a return spring 24. The cylinder 21 is used for air compression. The cylinder 21 is connected to the pressurizing box 6 through a pipe. The movable piston 22 is connected to the cylinder 21. The movable piston 22 is used to cooperate with the cylinder 21 to continuously compress the air into the pressurizing box 6. The two ends of the connecting rod 23 are respectively connected to the movable piston 22 and the seedling nozzle 3. The connecting rod 23 is made of acrylic material and has certain flexibility in the axial direction. It can be bent and reset multiple times. The return spring 24 is arranged inside the cylinder 21 and the return spring 24 is connected to the movable piston 22.

[0042] The connecting mechanism includes a three-way valve 25, which is also a solenoid valve. By controlling the different openings of the three-way valve 25, compressed air is supplied to the spray pipe 5 or the pressure relief valve 20. The input end of the three-way valve 25 is connected to the pressurizing box 6, and the output end of the three-way valve 25 is connected to the spray pipe 5 and the pressure relief valve 20 respectively.

[0043] Working principle: When the cylinder push rod 7 moves downward, the seedling nozzle 3 is in a closed state. When the seedling nozzle 3 enters the sand, the support leg 11 contacts the sand at a later time. The recoil force pushes the bearing sleeve 10 to move upward, driving the connecting rod 9 to move and rotate, causing the seedling nozzle 3 to rotate around the axis, thereby completing the opening and closing of the seedling nozzle 3;

[0044] When the seedling-planting nozzle 3 is opened, the connecting rod 23 is driven to move, thereby driving the movable piston 22 to move along the cylinder 21 (at this time, the return spring 24 is stretched), and the air is sucked into the cylinder 21. When the seedling-planting nozzle 3 is closed, the movable piston 22 is driven to reset under the joint action of the return spring 24 and the connecting rod 23;

[0045] During normal operation, the three-way valve 25 connects the spraying pipe 5 and the pressurizing box 6 to each other (at this time, the pneumatic push rod 15 is not connected to the pressurizing box 6), and the compressed air in the pressurizing box 6 will be input into the atomizer 14 through the spraying pipe 5 together with the waste material in the liquid storage box 4 for atomization, thereby enhancing the fertilization efficiency; when cleaning is needed, the three-way valve 25 connects the pneumatic push rod 15 and the pressurizing box 6 to each other (at this time, the spraying pipe 5 and the pressurizing box 6 are also connected to each other), and at this time, a part of the compressed air in the pressurizing box 6 will enter the cylinder 21 of the pneumatic push rod 15 to drive the telescopic end of the pneumatic push rod 15 to reciprocate, thereby driving the scraper block 19 to clean the dirt or dust attached to the outlet of the atomizer 14.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
