Abstract
Description
Technical Field
[0001] The invention relates to the technical field of forage grass sowing, and in particular to a saline-alkali land forage grass seeder and a use method thereof. Background Art
[0002] In the development process of modern agriculture, forage cultivation, as a basic link in the development of animal husbandry, has become increasingly important. However, in some special geographical environments and soil conditions, such as complex terrain areas such as saline-alkali land and mountainous areas, traditional forage sowing technology faces many challenges. Due to the limitations of natural conditions in these areas, traditional sowing methods are difficult to implement effectively, which will limit the development potential of local agriculture.
[0003] Existing forage seeders usually adopt an integrated design, integrating functions such as tilling, sowing and covering soil. A series of operations can be automatically completed by controlling the movement of the vehicle body. This method can show high efficiency and convenience in plain areas or large-scale farmlands, improving work efficiency and crop yields. However, the design of this equipment does not take into account all possible application scenarios, especially when facing rugged mountain roads. Its huge size and weight make transportation extremely difficult, and it may even be impossible to reach the target operation area. In addition, this type of machine usually relies on a lever to complete the covering process, that is, the lever is used to push the surrounding soil in the direction of the seed for covering. Although this method is effective under normal circumstances, it has obvious shortcomings in special environments such as saline-alkali land.
[0004] As a special type of soil, the physical and chemical properties of saline-alkali land pose unique challenges to the growth of crops. In order to adapt to the characteristics of saline-alkali land, farmers usually adopt the method of deep digging and shallow planting to reduce the impact of soil salt on seed germination. However, the lever covering mechanism used in the existing integrated forage seeder may cause the newly sown seeds to be moved again, causing the seeds to shift or be exposed, seriously affecting the accuracy of sowing and the final germination rate. This situation will not only reduce the sowing efficiency, but also affect the growth and yield of forage, and thus have an adverse impact on the development of animal husbandry. Summary of the invention
[0005] In view of this, the present invention provides a saline-alkali land forage seeder and a method of using the same, which can overcome the shortcomings of existing forage seeders, such as their huge size and weight making transportation extremely difficult or even unable to reach the target operating area when facing rugged mountain roads, and the lever covering mechanism used therein may cause the seeds just sown to be moved again, thereby reducing the sowing efficiency.

The connecting springs 14 are wound around the outside of the two latches 12, and the two ends of the connecting spring 14 are respectively connected to the latch 12 and the second mounting frame 2.
[0033] like Figure 7 and Figure 8 As shown, the unloading assembly includes a loading frame 15, a second handle 16, a guide frame 17, a roller motor 18 and a connecting tube 19. The loading frame 15 is connected to the upper part of the second mounting frame 2. The top and bottom of the loading frame 15 are both open-type designs. The second handle 16 is connected to the middle of the outer wall of the loading frame 15. The guide frame 17 is connected to the lower part of the second mounting frame 2. The guide frame 17 is arc-shaped and is located directly below the loading frame 15. A roller motor 18 is installed on the right part of the second mounting frame 2, and the roller motor 18 is located between the loading frame 15 and the guide frame 17.

The bottom of the loading frame 15 and the top of the guide frame 17 are in contact with the surface of the connecting tube 19, and storage grooves 1901 are circumferentially spaced on the surface of the connecting tube 19.
[0034] Initially, the connecting tube 19 blocks the bottom of the loading frame 15; first, put an appropriate amount of seeds into the loading frame 15, the connecting tube 19 can block the seeds in the loading frame 15, and then the controller 11 controls the electric push rod 4 to drive the connecting ring 5 to move downward, the connecting ring 5 can drive the brushless motor 6, the crushing wheel 7 and the rotating drum 8 to move downward, so that the crushing wheel 7 and the rotating drum 8 are in contact with the soil, and then the controller 11 can control the electric wheel 3, the brushless motor 6 and the drum motor 18 to start working, the electric wheel 3 can drive the seeder to move to the left, the brushless motor 6 can drive the crushing wheel 7 and the rotating drum 8 to rotate, the crushing wheel 7 can crush the hard lumps in the soil, and the rotating drum 8 can dig at intervals on the soil surface. The excavated soil will be temporarily stored in the storage groove 801 and rotate synchronously with the rotating cylinder 8, and the drum motor 18 can drive the connecting cylinder 19 to rotate. When the storage groove 1901 on the connecting cylinder 19 is aligned with the bottom of the loading frame 15, the seeds at the bottom of the loading frame 15 will fall into the storage groove 1901 and rotate synchronously with the connecting cylinder 19. When the guide frame 17 moves above the strip groove on the soil surface, the storage groove 1901 on the connecting cylinder 19 will be aligned with the top of the guide frame 17, and the seeds in the storage groove 1901 will fall down along the inner wall of the guide frame 17 into the strip groove on the soil surface. Then the soil in the storage groove 801 will rotate to the top of the strip groove on the soil surface. The soil in the receiving groove 801 will fall down into the strip groove on the soil surface and cover the seeds in the strip groove, so that the sowing and covering work can be completed automatically without affecting the sown seeds. After all the seeds are sown, the controller 11 controls the electric wheel 3, the brushless motor 6 and the drum motor 18 to stop working, and then the controller 11 controls the electric push rod 4 to drive the connecting ring 5 to move upward and reset. The connecting ring 5 can drive the brushless motor 6, the crushing wheel 7 and the rotating drum 8 to move upward and reset, so that the crushing wheel 7 and the rotating drum 8 are separated from the soil; when the seeder needs to be transported, the pull ring 13 can be pulled first to drive the latches 12 on the front and rear sides to move away from each other. The connecting spring 14 is stretched to disengage the latch 12 from the first circular hole 102, and then the second mounting frame 2 can be moved to the right to separate from the U-shaped insertion rod 101, and then the pull ring 13 is released, and the connecting spring 14 returns to its original state, driving the latches 12 on the front and rear sides to move toward each other and reset, so that the first mounting frame 1 and the second mounting frame 2 can be disassembled, which is convenient for transportation of the seed drill. When the seed drill is transported to the operating area, the first mounting frame 1 and the second mounting frame 2 can be reassembled and used by the cooperation of the latch 12 and the U-shaped insertion rod 101.

The middle of the upper part of the two rotating blocks 20 is slidably connected to the sliding block 22, and the rear part of the sliding block 22 clamps the front part of the arc block 21, so that the arc block 21 can be limited. The two ends of the return spring 23 are respectively connected to the sliding block 22 and the rotating block 20; when it is necessary to sow multiple rows at the same time, multiple seeders can be prepared, and the multiple seeders can be arranged at intervals from front to back, and then the front seeders on the front side can be moved. The sliding block 22 is pushed forward, and the return spring 23 is compressed, so that the sliding block 22 is disengaged from the arc block 21, and then the arc block 21 can be rotated to open, and then the rotating block 20 is rotated backward until it contacts the first handle 10 and the second handle 16 on the rear seeder, and then the arc block 21 is reversed and closed, so that the rotating block 20 and the arc block 21 on the front seeder can cooperate to buckle the first handle 10 and the second handle 16 on the rear seeder, and then the sliding block 22 is released, and the return spring 23 will return to its original state, driving the sliding block 22 to move backward and re-clamp the arc block 21 to prevent the arc block 21 from rotating and opening, so that multiple seeders can be connected. When multiple seeders are sowing at the same time, the intervals between each row of seeds can be ensured to be consistent.
[0036] like Fig.11 As shown, it also includes a connecting frame 24, a hook 25 and a cutting assembly. The connecting frame 24 is connected to the left side of the top of the loading frame 15, and the hook 25 is symmetrically connected to the upper right side of the connecting frame 24. The cutting assembly is used to cut the packaging bags hung on the hook 25; the cutting assembly includes a guide rod 26, a movable block 27 and a cutter 28. The upper part of the inner wall of the material frame 15 is connected to the guide rod 26, the outer side of the guide rod 26 is sleeved with a movable block 27, and the bottom of the movable block 27 is connected to the cutter 28; when the seeder needs to be used, A bag of seeds can be directly hung on the hook 25, and then the movable block 27 is rotated to drive the cutter 28 to rotate toward the packaging bag containing the seeds, and then the movable block 27 is slid along the guide rod 26 to drive the cutter 28 to move linearly to cut the packaging bag, so that the seeds can automatically fall into the loading frame 15 due to gravity. When the loading frame 15 is full of seeds, the seeds will block the incision of the packaging bag, thereby automatically stopping the loading. When the seeds in the loading frame 15 gradually decrease, the seeds in the packaging bag will be automatically replenished.
[0037] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
