Description

Technical Field

[0001] The invention relates to the technical field of hilly grassland reseeding, and in particular to a no-tillage reseeding machine suitable for hilly grassland in the south. Background Art

[0002] Southern hilly grassland refers to grassland distributed in the southern hilly areas, mainly in the vast area south of the Qinling Mountains-Huaihe River and east of the Qinghai-Tibet Plateau. The terrain is complex, including plains, basins, plateaus and hills. Grassland resources can also be used for animal husbandry, providing forage resources and supporting local economic development. Southern hilly grasslands, such as some sloping pastures in Yunnan Province, are currently showing signs of degradation due to poor management, and restoration measures are urgently needed.

[0003] Because the hilly ground is relatively uneven, the conventional reseeding measure currently adopted is to carry seeds manually for sowing. This sowing efficiency is low and it is easy to miss holes without sowing. In addition, the reseeding area needs to be watered after sowing. After the seeds are piled up on the bottom for a long time, they will also become bad due to squeezing and accumulation when carried. Therefore, a no-till reseeding machine suitable for southern hilly grasslands is provided to solve the above-mentioned problems. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned prior art, the present invention provides a no-tillage seeding machine suitable for southern hilly grasslands.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a no-tillage sowing machine suitable for hilly grasslands in the south, comprising a sowing box and a wet soil box, wherein a plurality of first support assemblies, a second support assemblies and a third support assemblies arranged in parallel are arranged below the sowing box and the wet soil box, characterized in that: the tops of the plurality of third support assemblies are fixed to the wet soil box, the tops of the plurality of second support assemblies and the first support assemblies are fixed to the bottom of the sowing box, a seed outlet tube is provided at the bottom of the sowing box, a plurality of groups of sowing stirring members for stirring sowing seeds are installed inside the sowing box, and each of the second support assemblies is connected to the adjacent sowing stirring members;

[0006] The first supporting components, the second supporting components and the third supporting components are all composed of a bottom wheel, a hub positioning frame, a telescopic rod and a shock-absorbing spring, wherein the bottom wheel is mounted on the hub positioning frame, the shock-absorbing spring is sleeved on the telescopic rod, and the bottom ends of the shock-absorbing spring and the telescopic rod are both attached to the hub positioning frame;

[0007] Among them, a plurality of first support assemblies, second support assemblies and third support assemblies assist the reseeding boxes and wet soil boxes in reseeding grass seeds in the potholes on the hill surface.

[0008] Preferably, a seed inlet tube is installed on the top of the reseeding box, and the cross-sectional area of ​​the top opening of the seed inlet tube is smaller than the cross-sectional area of ​​the bottom opening.

[0009] Preferably, the wet soil box comprises a water tank, a water inlet pipe is installed on the top of the water tank, a water pump is installed on the bottom of the water tank, the water inlet of the water pump is connected to the water tank, and the water outlet end of the water tank is connected to the water outlet pipe.

[0010] Preferably, the water outlet pipe is provided with a plurality of sprinkler heads for spraying toward the land.

[0011] Preferably, a baffle is slidably connected inside the seed outlet tube, a support frame is installed at the bottom of the baffle, and the support frame is fixed to the seeding stirring member.

[0012] Preferably, the sowing stirring member comprises a connecting tooth plate, the connecting tooth plate is fixed to the support frame, and the cross-section of the baffle plate is inclined when viewed from the side.

[0013] Preferably, the sowing stirring member also includes a first gear, a second gear, a central rotating rod, two linked rotating rods and two auxiliary stirring rods. The first gear, the second gear, the central rotating rod, the two linked rotating rods and the two auxiliary stirring rods are all rotatably connected to the inner wall of the reseeding box. The bottom of the second gear is meshed with the first gear. The first gear is transmission-connected to the toothed surface of the connecting tooth plate. A transmission belt is transmission-connected between the second gear and the central rotating rod, and between the linked rotating rod and the auxiliary stirring rod.

[0014] Preferably, a conical gear ring is installed on one end of the two linkage rotating rods close to the central rotating rod, and the three conical gear rings are arranged and meshed in a U shape.

[0015] Preferably, a main stirring rod is installed at the bottom of the central rotating rod, and the two auxiliary stirring rods are arranged perpendicular to the main stirring rod.

[0016] Compared with the prior art, the present invention provides a no-tillage seeding machine suitable for southern hilly grasslands, which has the following beneficial effects:

[0017] 1. The design of the device fully considers the characteristics of hilly terrain. Water and seeds are poured into the water tank and seeding box through the water inlet pipe and seed inlet pipe respectively. In the initial state, each component will be compressed due to pressure and gravity to ensure the stability of the device during movement.

[0018] 2. When the device encounters potholes on hilly ground, its unique support assembly begins to work. The first support assembly extends first, and uses the scratching wheel to scratch a seed pit in the pit. Then, the second support assembly enters the pit and extends. During this process, the connecting tooth plate will drive the baffle to move down, revealing the bottom gap of the seed tube, allowing the seeds to leak out and be sown in the pit. At the same time, the connecting tooth plate also drives the gears and transmission belts to rotate, and then drives the central rotating rod, the main stirring rod and the auxiliary stirring rod to rotate, forming a turning of the seeds in the seeding box. This turning not only increases the contact area between air and seeds, prevents damage to seeds caused by bad seeds or excessive stacking temperature, but also improves the efficiency of turning.

[0019] 3. The extension and retraction of the second support assembly of the device not only realizes the reseeding in the pit, but also links the sowing stirring piece through its support and reset effect to mix the seeds in the reseeding box. This linkage design enables the device to automatically close the seed outlet tube when it moves out of the pit until it enters the next sowing location.

[0020] The no-till reseeding machine achieves efficient semi-automatic reseeding through its ingenious design and linkage structure, greatly improving the reseeding effect and efficiency. It can adapt to various hilly surfaces and provide strong support for vegetation restoration and ecological improvement of southern hilly grasslands. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0031] like Figure 1-Figure 7 As shown, this embodiment proposes a no-tillage sowing machine suitable for hilly grasslands in the south, including a sowing box 1 and a wet soil box 2. A plurality of first support assemblies 3, a second support assembly 4 and a third support assembly 5 arranged in parallel are arranged below the sowing box 1 and the wet soil box 2. The characteristics are as follows: the tops of the plurality of third support assemblies 5 are fixed to the wet soil box 2, the tops of the plurality of second support assemblies 4 and the first support assemblies 3 are all fixed to the bottom of the sowing box 1, a seed outlet tube 11 is provided at the bottom of the sowing box 1, a plurality of groups of sowing stirring members 7 for stirring sowing seeds are installed inside the sowing box 1, and each second support assembly 4 is connected to the adjacent sowing stirring member 7;

[0032] The plurality of first support assemblies 3, the second support assemblies 4 and the third support assemblies 5 are all composed of a bottom wheel, a wheel hub positioning frame, a telescopic rod and a shock-absorbing spring. The bottom wheel is mounted on the wheel hub positioning frame, the shock-absorbing spring is sleeved on the telescopic rod, and the bottom ends of the shock-absorbing spring and the telescopic rod are both on the wheel hub positioning frame;

[0033] Among them, a plurality of first support assemblies 3, second support assemblies 4 and third support assemblies 5 assist the reseeding box 1 and the wet soil box 2 to replant grass seeds in the potholes on the hill surface.

[0034] In this embodiment, a seed inlet tube 12 is installed on the top of the seed reseeding box 1. The cross-sectional area of ​​the top opening of the seed inlet tube 12 is smaller than the cross-sectional area of ​​the bottom opening. The seed inlet tube 12 is provided to facilitate filling of seeds. This design of small top and large bottom can increase the seed storage capacity of the seed reseeding box 1 while reducing the entry of dust.

[0035] Multiple first support assemblies 3, second support assemblies 4 and third support assemblies 5 are all composed of bottom wheels, wheel hub positioning frames, telescopic rods and shock-absorbing springs. The bottom wheels are installed on the wheel hub positioning frames, the shock-absorbing springs are sleeved on the telescopic rods, and the bottom ends of the shock-absorbing springs and the telescopic rods are both on the wheel hub positioning frames.

[0036] This design allows the first support assembly 3, the second support assembly 4 and the third support assembly 5 to jointly support the reseeding box 1, the wet soil box 2 and the first support assembly 3, and can also have a good adaptability effect on the inclined slope of the hill, and the whole body has soft contact when encountering stones on the hill surface, reducing the possibility of damage to the first support assembly 3, the second support assembly 4 and the third support assembly 5 or causing the reseeding box 1 to tip over.

[0037] The wet soil box 2 includes a water tank 22, a water inlet pipe 21 is installed on the top of the water tank 22, a water pump 23 is installed on the bottom of the water tank 22, the water inlet of the water pump 23 is connected to the water tank 22, and the water outlet end of the water tank 22 is connected to the water outlet pipe 24;

[0038] A plurality of sprinkler heads 25 are installed on the water outlet pipe 24 to spray toward the land;

[0039] The wet soil box 2 is designed to add water to the replanted seeds, and after adding water through the water inlet pipe 21, it is guided by the water pump 23 to the water outlet pipe 24 and then discharged through the sprinkler head 25 to achieve drip irrigation;

[0040] Furthermore, during the irrigation process of the wet soil box 2, if it is inconvenient to supply electricity, the water pump 23 can be replaced with an ordinary valve, and the aperture of the sprinkler head 25 can be enlarged, and the water inlet pipe 21 is in an open state. In this way, when irrigation is needed, it is only necessary to open the valve to irrigate by gravity, but this is inconvenient to adjust the amount of irrigation water.

[0041] A baffle plate 6 is slidably connected inside the seed outlet tube 11 , a support frame 61 is installed at the bottom of the baffle plate 6 , and the support frame 61 is fixed to the seeding stirring member 7 .

[0042] The baffle 6 can close or open the seed discharging tube 11 through the linkage with the sowing stirring member 7.

[0043] The sowing stirring member 7 includes a connecting tooth plate 71, the connecting tooth plate 71 is fixed to the support frame 61, and the cross section of the baffle plate 6 is inclined when viewed from the side;

[0044] The sowing stirring member 7 also includes a first gear 72, a second gear 73, a central rotating rod 74, two linked rotating rods 76 and two auxiliary stirring rods 77. The first gear 72, the second gear 73, the central rotating rod 74, the two linked rotating rods 76 and the two auxiliary stirring rods 77 are all rotatably connected to the inner wall of the seed supplement box 1. The bottom of the second gear 73 is meshed with the first gear 72. The first gear 72 is transmission-connected to the toothed surface of the connecting tooth plate 71. A transmission belt 78 is transmission-connected between the second gear 73 and the central rotating rod 74 and between the linked rotating rod 76 and the auxiliary stirring rod 77.

[0045] The ends of the two linkage rotating rods 76 close to the central rotating rod 74 are both equipped with conical gear rings, and the three conical gear rings are arranged and meshed in a U shape;

[0046] A main stirring rod 75 is installed at the bottom of the central rotating rod 74 , and two auxiliary stirring rods 77 are arranged perpendicular to the main stirring rod 75 .

[0047] The sowing stirring member 7 is used to realize the main stirring rod 75 and the auxiliary stirring rod 77 cooperating to stir the seeds inside the seeding box 1, and the connecting tooth plate 71 can also cooperate with the second support component 4 to open or close the seed outlet tube 11, making the overall operation more convenient, and the baffle 6 is inclined when viewed from the side in order to sow the seeds in a direction toward the rear pit to prevent the seeds from leaking out.

[0048] Furthermore, although the first support assembly 3, the second support assembly 4 and the third support assembly 5 have the same overall structure, the bottom wheels in the internal structure are different. The three bottom wheels are a scratching wheel, a seeding wheel and a pressing wheel. The scratching wheel touches the ground sharply and is mainly used to scratch the grass, while the seeding wheel is thinner as a whole, but the seeding wheel as a whole is mainly linked to the baffle 6 and the seeding agitator 7 to sow seeds when encountering bumpy ground, and the pressing wheel is used to smooth the ground.

[0049] Furthermore, the wet soil box 2 can be divided into two chambers, one chamber is for water supply, and the other chamber is open at the bottom, and the soil falls down under the action of gravity by shaking, just covering the soil after replanting and watering.

[0050] Furthermore, the top of the central rotating rod 74 extends out of the top of the seed supplement box 1, and the central rotating rod 74 can be directly rotated to directly stir the seeds.

[0051] Working principle and use method of the present invention:

[0052] The device is divided into two parts: a reseeding box 1 and a wet soil box 2. The reseeding box 1 is used for reseeding, and the wet soil box 2 is used for watering. When the whole device is in the southern hilly grassland, the whole device can be moved by pushing;

[0053] Before departure, water is poured into the water tank 22 through the water inlet pipe 21, and some nutrients can be added, and then the seeds for replanting are poured into the replanting box 1 through the seed inlet pipe 12. In the initial state, the pressure of the replanting box 1, the wet soil box 2, the seeds, the water, etc. will compress the first support assembly 3, the second support assembly 4 and the third support assembly 5, and the baffle 6 is pressed into the seed outlet pipe 11;

[0054] When passing through a hilly ground, first, the first support assembly 3 reaches out after encountering a pothole and uses the scratching wheel to scratch a seed pit in the pit. Then, after the first support assembly 3 leaves the pothole, the second support assembly 4 enters the pothole. When the second support assembly 4 enters the pothole, it will extend. During the extension process, the connecting tooth plate 71 will move downward, and the connecting tooth plate 71 drives the baffle 6 to move downward through the support frame 61 until the baffle 6 leaks out, and a gap is generated at the bottom of the seed tube 11, which will leak the seeds, and the connecting tooth plate 71 drives the first gear 72 to rotate, and the first gear 72 meshes with the second gear 73. After closing, the central rotating rod 74 is driven to rotate by the second gear 73 and the adjacent transmission belt 78. The central rotating rod 74 not only drives the main stirring rod 75 to rotate, but also drives the corresponding auxiliary stirring rods 77 to rotate through the linkage rotating rod 76 and the transmission belts 78 on both sides, thereby forming a seed turning over inside the seed refilling box 1. Under such operation, the extension and retraction of the second supporting assembly 4 can not only replenish the seeds in the pit, but also turn over the seeds inside the seed refilling box 1, increase the contact area between air and seeds, and prevent damage to seeds caused by bad seeds or excessive stacking temperature;

[0055] The horizontal and vertical design of the main stirring rod 75 and the auxiliary stirring rod 77 stirs the seeds from multiple directions, preventing the seeds from sinking to the bottom all the time, and also increasing the efficiency of the turning;

[0056] That is, the second support assembly 4 can not only support the movement of the reseeding box 1 and the wet soil box 2, but also can sow when encountering potholes and use its own support and reset effects to drive the sowing stirring member 7 to mix the seeds in the reseeding box 1. When walking out of the potholes, the seed outlet tube 11 will be closed until entering the next location, and the subsequent cooperation of the wet soil box 2 can also carry out preliminary watering of the seeds, realizing semi-automatic reseeding of potholes. Finally, the third support assembly 5 can bring out some soil next to the potholes, cover the potholes with soil and slightly flatten it, which is convenient for subsequent operations.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0058] Although the 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
