[0030] Embodiment 1: Figure 1 As shown, a high-speed continuous seeder for agriculture includes a chassis 1, a driving assembly 2, a sowing assembly 3, a furrowing member 4, a hole pressing assembly 5 and a first soil covering member 6. The driving assembly 2 is connected to the chassis 1, and the sowing assembly 3 is arranged on the chassis 1.

[0031] For reference, the chassis 1 serves as the supporting base of the entire seeder, and has sufficient strength and stability to ensure the smooth operation of the seeder during operation. The drive assembly 2 is connected to the chassis 1 and is responsible for providing power for the seeder to move forward. Specifically, the drive assembly 2 is a conventional structure, including a drive wheel and a drive motor. The drive motor is fixed to the chassis 1 and is connected to the drive wheel through a transmission device (such as a gear, chain or belt, etc.). When the drive motor is working, the drive wheel is driven to rotate through the transmission device, thereby pushing the entire seeder forward on the ground. The power and speed of the drive motor can be adjusted according to actual operation requirements to meet the needs of different sowing operations.

[0032] like Figure 2 and Figure 3 As shown, two first support members 101 are disposed opposite to each other at the front end of the chassis 1 , and a gap is disposed between the two first support members 101 .

[0033] For reference, the two first support members 101 can be designed as sturdy and durable structural members, for example, made of metal materials (such as steel or aluminum alloy) to ensure that other components can be stably supported during the operation of the seeder. Each first support member 101 can be a bracket with a fixed shape and size, on which a connection hole or mounting groove can be designed to connect with other components (such as a trenching member 4 or a second support member 501). The two first support members 101 can be installed on the chassis 1 by welding, bolting or other fastening methods. The two first support members 101 maintain a certain gap. This gap is to provide sufficient space for the hole pressing member 503 of the hole pressing assembly 5 so that a planting hole can be pressed out in the groove during rotation.

[0034] The groove opening member 4 is connected to the first supporting member 101 , and the groove opening member 4 is used for opening grooves.

[0035] For reference, the furrowing member 4 is a commonly used furrowing tool. For example, the furrowing tool can be a metal blade with a sharp blade, and its shape and size are designed according to the specific needs and working conditions of the seed drill. Usually, the blade of the furrowing member presents a certain arc or angle so that it can smoothly cut into the soil and open a groove when moving forward. The furrowing member can be provided with a connecting hole, and the first support member is correspondingly provided with a bolt hole. By passing the bolt through the connecting hole of the furrowing member and the bolt hole of the first support member, and tightening with a nut, a firm connection between the furrowing member and the first support member can be achieved.

[0036] The first soil covering member 6 is disposed at the end of the chassis 1. For reference, the first soil covering member 6 is usually designed as a plate-like structure with a certain width and length, and its material can be selected from a sturdy and durable metal or plastic. The first soil covering member 6 is connected to the end of the chassis 1 by welding, bolting, and riveting. When the seeder moves forward, the soil can be smoothly pushed into the planting hole by the first soil covering member 6 and cover the planting hole.

[0037] The hole-pressing assembly 5 includes two relatively arranged second supporting members 501, a first rotating member 502, and a hole-pressing member 503. The second supporting member 501 is arranged on the first supporting member 101. The first rotating member 502 is rotatably connected to the second supporting member 501. The hole-pressing member 503 is connected to the first rotating member 502, and the hole-pressing member 503 is located in the gap.

[0038] For reference, the second support member 501 is generally a support structure made of a solid and durable material. The second support member 501 may be designed in a plate or column shape and may include mounting holes or grooves thereon so as to be connected with the first support member 101 and the first rotating member 502. Specifically, in this embodiment, Figure 2 and Figure 3 As shown, the second support member 501 includes a horizontal support plate and a ring-like plate, and a through hole is arranged on the ring plate. The first rotating member 502 can be an axis, a rod or other forms of rotating structures. The first rotating member 502 is a component that can rotate relative to the second support member 501. It usually has a bearing structure, so that the hole pressing member 503 can rotate in the groove and press out the planting hole as the seeder moves forward. The material needs to have a certain strength and wear resistance to ensure that the stable rotation performance can be maintained during long-term operation.

[0039] The hole pressing member 503 is a part that directly contacts the soil and is used to press out a planting hole in the groove. The hole pressing member 503 can be designed as a blade or roller with a specific shape and size, and at least one protrusion 504 is provided on its side wall. These protrusions can press out a planting hole that meets the requirements in the groove during rotation. The material of the hole pressing member 503 needs to have sufficient hardness and wear resistance to ensure that it can remain sharp and stable during operation.

[0040] The sowing component 3 is conventionally configured. In the present embodiment, the sowing component 3 includes a third support member 301, a sowing box 302, and a conveying pipe 303. The third support member 301 is disposed on the chassis 1, and the sowing box 302 is disposed on the third support member 301. The conveying pipe 303 is connected to the discharge port of the sowing box 302, and the discharge end of the conveying pipe 303 is located on one side of the hole-pressing member 503.

[0041] For reference, the third support member 301 can generally be designed as a sturdy bracket or frame with a certain height so as to lift the seed box 302 to a suitable height. The third support member 301 can be made of metal (such as steel or aluminum alloy) or other durable materials to ensure that it can withstand the weight of the seed box 302 and the vibration and impact that may occur during operation.

[0042] The structure of the third support member 301 can be designed according to the shape and size of the seed box 302 to ensure that the seed box 302 can be stably placed thereon. It can include a horizontal support plate, a vertical support column, and a beam or a reinforcing rib connecting these components. In addition, the third support member 301 can be connected to the chassis 1 by welding, bolting or other fastening methods to ensure that it is firmly fixed to the chassis 1.

[0043] In this embodiment, the seeder is started, and the drive assembly 2 starts to work. Through the cooperation of the drive wheel and the drive motor, the entire seeder is pushed forward on the ground. During the advancement of the seeder, the furrowing member 4 contacts the soil and uses the blade to open a groove of a certain depth and width on the soil. This groove provides the necessary space for subsequent sowing and covering operations. The hole pressing member 503 contacts the ground. As the seeder advances, the hole pressing member 503 rotates, and the protrusion 504 presses out a planting hole in the groove. The sowing box 302 transports most of the seeds into the groove through the conveying pipe 303. The seeder continues to move forward, and the first covering member 6 begins to cover the groove and the planting hole. The first covering member 6 pushes the soil into the groove, covering the planting hole and the seeds, completing the entire process of sowing and covering.

[0044] Embodiment 2: In order to make the hole pressing member enter the soil more easily and take away more soil, so as to make the planting hole larger, Figure 4As shown, the protrusion 504 includes a fixed end 505 and a force-bearing end 506, the fixed end 505 is welded to the hole-pressing member, and the cross section of the protrusion 504 gradually decreases from the fixed end to the force-bearing end, making the force-bearing end sharper and easier to cut into the soil.

[0045] The side wall of the force-bearing end 506 is provided with a soil expansion member 507, which includes two wing plates, which are arranged oppositely on the side wall of the force-bearing end 506. When the hole-pressing member rotates in the soil, the two wing plates will scoop up and take away the soil like a shovel, thereby further expanding the size of the planting hole, increasing the volume of the planting hole and providing a better growth space for the seeds.

[0046] Embodiment 3: Figure 5 and Figure 6 As shown, the front end of the chassis 1 is also provided with a fixing member 102, and the fixing member 102 includes a connecting portion 103 and a fixing portion 104. The connecting portion 103 is connected to the chassis 1, and the connection can be welding, bolt connection or other mechanical connection methods. The fixing portion 104 is provided with a through hole, and the through hole is adapted to the discharge end of the conveying pipe 303. The size and shape of the through hole are adapted to the discharge end of the conveying pipe 303, so that the discharge end of the conveying pipe 303 can be tightly inserted into the through hole. The fixing member 102 can prevent the conveying pipe from shaking around during sowing, thereby increasing the probability of seeds falling from the discharge end of the conveying pipe 303 into the planting hole.

[0047] Embodiment 4: Considering that when the trenching member is trenching, the soil will be distributed on both sides of the trench, and when the hole pressing member rotates, the soil will also be brought out. In order to improve the soil covering effect, Figure 7 and Figure 8 As shown, a second covering member 7 is disposed at the bottom of the fixing member 102 . The second covering member 7 is V-shaped, and the inner wall of the V-shaped second covering member 7 is welded to the inner wall of the fixing member 102 .

[0048] The open end of the second soil covering member 7 faces the hole pressing member 503, and the inner diameter of the furrowing end of the second soil covering member 7 is larger than the width of the soil expanding member 507. This V-shaped design enables the second soil covering member to effectively gather the soil on both sides and push it toward the planting hole like a shovel when in operation. Its open end faces the hole pressing member, ensuring that after the hole pressing member completes the hole pressing operation, the second soil covering member can immediately carry out preliminary soil covering on the planting hole. The inner diameter of the furrowing end of the second soil covering member is designed to be larger than the width of the soil expanding member. This design is to avoid interference between the soil expanding member and the second soil covering member during rotation, ensuring that both can work smoothly.

[0049] The first soil covering member 6 is also V-shaped, and the opening end of the first soil covering member 6 faces the second soil covering member 7; the inner diameter of the opening end of the first soil covering member 6 is larger than the trenching width of the trenching member 4. The first soil covering member 6 can effectively gather the soil on both sides of the trenching groove and push it toward the planting hole for secondary soil covering, thereby improving the soil covering effect.

[0050] The ditching member 4, the hole pressing assembly 5, the first soil covering member 6, the second soil covering member 7 and the discharge end of the conveying pipe 303 are located on the same horizontal line. It is ensured that during the operation of the seeder, the work process from ditching to planting and then to two soil coverings can be completed on a coherent horizontal line. The ditching member opens a groove during the forward movement to prepare for the subsequent hole pressing and planting operations. Then, the hole pressing member presses out the planting hole in the groove to provide space for the planting of seeds. At the same time, the discharge end of the conveying pipe ensures that the seeds can accurately fall into the planting hole. Subsequently, the first soil covering member follows the hole pressing member and performs preliminary soil covering on the planting hole, covering part of the seeds and the planting hole. The purpose of this step is to fix the position of the seeds and prevent them from shifting. Immediately afterwards, the second soil covering member covers the planting hole again to further ensure that the seeds are completely covered by the soil. Since the second soil covering member is located after the first soil covering member, it can effectively gather the soil that may be left around the planting hole and push it into the hole, thereby achieving a more comprehensive soil covering effect.

[0051] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
