Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seeding roller. Background Technology

[0002] During sowing operations, the soil surface after tillage often forms an irregular uneven surface due to the limited precision of tillage equipment. These uneven surfaces are mostly manifested as local soil clods piled up and shallow depressions interspersed, with some areas having a height difference of 3-5 centimeters. The uneven size of the soil clod particles further exacerbates the surface unevenness. When the seeding stage begins, the seeder moves the seeding roller, which then contacts the soil. Traditional seeding rollers primarily rely on their own weight to apply pressure to the soil, achieving a basic leveling effect through roller rolling. The surrounding planting components also contact the soil as the roller rolls, naturally embedding themselves into the soil with the help of the roller's gravity, thus creating planting holes for sowing. However, when the unevenness of the soil surface exceeds a certain range, the seeding roller relying solely on its own weight cannot effectively complete the initial leveling: this will cause the roller to have a certain skew angle, which in turn will cause the pitting components around the roller to be crooked, ultimately resulting in some planting pits failing to meet the required depth. Utility Model Content

[0003] The main purpose of this utility model is to provide a sowing roller in which the circumferentially arrayed plates on the shaft rotate with the shaft, and apply a periodic downward force to the roller by successively rising and falling. Combined with the roller vibration allowed by the seeder, it can not only efficiently flatten the uneven soil after tilling and ensure that the planting hole component can be smoothly inserted into the soil, but also ensure that the planting hole depth meets the standard through continuous pressure, effectively avoiding the problem of planting hole failure due to uneven soil or seed waste caused by planting hole being too shallow.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A seeding roller includes a roller body, a shaft fixed at the center of the roller body, and pitting components provided on both sides of the circumference of the roller body. The roller body has a hollow structure. A plurality of eccentric components are arranged circumferentially along the length of the shaft located inside the roller body. Each eccentric component includes a plate body, which is rotatably connected to the shaft body through a through hole. An arc-shaped limiting groove is provided on the inner wall of the through hole, and a connecting plate is slidably connected in the arc-shaped limiting groove. The connecting plate is fixedly connected to the shaft body.

[0005] Furthermore, the pitting assembly includes a belt disposed on the circumferential surface of the roller, and protrusions are welded at equal intervals on the outer circumferential surface of the belt.

[0006] Furthermore, the belt has two free ends, and a fixing plate is welded to one side of each of the two free ends. The two fixing plates are fixedly connected by bolts.

[0007] Furthermore, the protrusion is triangular.

[0008] Furthermore, the roller body has baffles on both sides, and the shaft body is fixedly connected to the two baffles.

[0009] Furthermore, buffer rubber pads are glued to both ends of the arc-shaped limiting groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects: As the shaft rotates, the circumferential array of plates on the shaft of this invention applies a periodic downward force to the rollers by sequentially rising and falling. Combined with the roller vibration allowed by the seeder, this can efficiently flatten the uneven soil after tilling, ensuring that the planting hole component can be smoothly inserted into the soil. At the same time, the continuous pressure can ensure that the planting hole depth meets the standard, effectively avoiding the problem of planting hole failure due to uneven soil or seed waste caused by planting holes that are too shallow.

[0011] The buffer rubber pad inside the arc-shaped limiting groove of this invention can reduce the impact of collision between the connecting plate and the groove end, and reduce component wear.

[0012] The belt of this invention is detachably fixed by a fixing plate and bolts, which can stably fit the roller surface and prevent the belt from loosening or shifting during operation. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figure 1-8As shown, a seeding roller includes a roller body 1, a shaft 2 fixed at the center of the roller body 1, and pitting components on both sides of the circumference of the roller body 1. The roller body 1 has a hollow structure. The shaft 2 located inside the roller body 1 has a plurality of eccentric components arranged circumferentially along its length. The eccentric components include a plate 4, which is rotatably connected to the shaft 2 through a through hole 402. An arc-shaped limiting groove 401 is provided on the inner wall of the through hole 402. A connecting plate 404 is slidably connected in the arc-shaped limiting groove 401. The connecting plate 404 is fixedly connected to the shaft 2. The shaft 2, roller body 2, eccentric components and pitting components are all made of iron.

[0027] In this embodiment, such as Figure 3 and Figure 6 As shown, since several eccentric components are arranged in a circular array along the length of the shaft 2, when the shaft 2 rotates by a certain angle, the plate 4 of one eccentric component falls down and applies a force to the roller 1. The roller 1 is connected to the seeder through the shaft 2. The seeder allows the roller 1 to vibrate. Therefore, when the plate 4 falls down, the roller 1 can better flatten the turned soil due to vibration, so that the pit-making component can make pits in the soil, avoiding the pit-making component being unable to make pits due to the unevenness of the soil surface after turning over the soil.

[0028] This seeding roller has a hollow structure, and the applied force only flattens the soil, without completely compacting the tilled soil.

[0029] like Figure 1 and Figure 7 As shown, the planting hole assembly includes a belt 3 disposed on the circumferential surface of the roller 1. Protrusions 301, triangular in shape, are welded equidistantly to the outer circumferential surface of the belt 3. When the shaft is connected to the seeder, the seeder drives the roller 1 to move in the field. The seeder's power is transmitted to the shaft 2 via a chain and sprocket, causing the roller 1 to rotate. During the rotation of the roller 1, the belt 3 rotates along with it, causing the protrusions 301 to penetrate the soil, creating planting holes so that seeds can fall into them. During this process, several plates 4 follow the rotation of the shaft 2, rising and falling sequentially, thus applying a downward force to the roller 1. Within the limits allowed by the seeder, this causes the roller 1 to vibrate and press down on the soil, ensuring that the planting holes created by the protrusions 301 meet the planting requirements and preventing seed waste due to shallow planting holes.

[0030] like Figure 7 and Figure 8As shown, the belt body 3 has two free ends 304, and a fixing plate 302 is welded to one side of each of the two free ends 304. The two fixing plates 302 are fixedly connected by bolts 303. The two fixing plates 302 have mating holes. After the bolts 303 pass through the mating holes and are connected with nuts, the two free ends 304 can be fixedly connected, thereby stably fixing the belt body 3 to the outside of the roller body 1. In addition, a rubber strip can be set between the roller body 1 and the belt body 3 to further improve the connection stability between the roller body 1 and the belt body 3.

[0031] Among them, such as Figure 2 As shown, the roller body 1 has baffles 5 on both sides, and the shaft body 2 is fixedly connected to the two baffles 5. The baffles 5 are welded to both sides of the roller body 1. When the shaft body 2 rotates, it can drive the roller body 1 to rotate through the baffles 5.

[0032] Among them, such as Figure 3 As shown, buffer rubber pads 403 are glued to both ends of the arc-shaped limiting groove 401. The rubber pads 403 can prevent the connecting plate 404 from colliding with the inner ends of the arc-shaped limiting groove 401.

[0033] Working principle: The shaft 2 is powered and rotated by the chain and sprocket of the seeder. The roller 1 is driven to rotate synchronously by the baffles 5 on both sides. The protrusions 301 on the belt 3 that rotate with the roller 1 are driven into the soil to form planting holes. During this process, the eccentric components (plates 4) in the circumferential array on the shaft 2 fall down in sequence as the shaft 2 rotates, applying a downward force to the roller 1. Combined with the vibration of the roller 1 allowed by the seeder, the soil is flattened to ensure that the protrusions 301 can successfully make holes and to ensure that the planting hole depth meets the standard. The buffer rubber pad 403 of the arc-shaped limiting groove 401 reduces the collision between the connecting plate 404 and the groove end, realizing efficient and stable sowing operation.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
