Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeding equipment technology, and more specifically, to a seeding machine grass skid and a triangular seeding machine. Background Technology
[0002] To improve germination rate and yield, the triangular sowing method is now widely used. This method involves a specific layout of the seeds in the field, arranging the plants in a triangular pattern. The principle behind this is to maximize land use and increase yield and economic benefits through appropriate spacing between rows and rows.
[0003] To improve sowing quality and ensure strong seedling emergence, triangular seeders require furrowing and fertilization during the sowing process. However, during furrowing, weeds in the field can easily become entangled on the furrow opener, affecting subsequent furrowing efficiency and fertilization quality. In severe cases, it can even cause the furrow opener tip to bend, increasing the power consumption of the tractor. Some seeders now have grass skids on the furrow opener, but during use, weeds easily become entangled on the entire skid, making cleanup difficult. Utility Model Content

[0028] like Figure 1 As shown, this embodiment provides a grass skimmer for a seeder, including a connecting bracket 4 and a furrow opener 2 connected to one end of the connecting bracket 4. A rotatable grass skimmer 1 is connected to the upper side of the furrow opener 2. The grass skimmer 1 is cylindrical and vertically arranged. Furthermore, the grass skimmer 1 includes at least a first roller body 10 and a second roller body 11 connected together. The middle section of the first roller body 10 bulges outward toward the grass skimmer 1, and the diameter of the first roller body 10 gradually decreases from its middle section to its two ends. The middle section of the second roller body 11 bulges outward toward the grass skimmer 1, and the diameter of the second roller body 11 gradually decreases from its middle section to its two ends. A recessed roller body connection area 111 is formed at the connection between the first roller body 10 and the second roller body 11.
[0029] It should be noted that in other schemes, in some cases the grass skiing roller 1 can also be provided with more than two roller bodies, whose structure and connection are consistent with the first roller body 10 and the second roller body 11.
[0030] In this embodiment, the grooving tool 2 has a grooving pear tip 201 on the side facing forward, and an arc-shaped side 203 on the side facing forward of the grooving pear tip 201.
[0031] It should be noted that in this embodiment, the grass skimmer is mounted on the seeder. During the sowing process, the furrow opener 2 opens furrows for subsequent fertilization. Therefore, the direction in which the grass skimmer moves forward is defined as "forward", the direction opposite to the forward direction is defined as "backward", the direction away from the field surface is defined as "up", and the direction towards the ground is defined as "down".
[0032] In this embodiment, since weeds are common in the field, during the ditching process, the ditching tip 201 on the front side of the ditch opener 2 extends into the soil, and weeds become entangled on the ditch opener 2. To slide or push the weeds away and prevent them from gathering and tangling on the ditch opener 2, a grass-sliding roller 1 is provided on the upper side of the ditch opener 2. The grass-sliding roller 1 is hollow inside and cylindrical. The grass-sliding roller 1 can rotate without power. When the weeds are pushed to the grass-sliding roller 1 by the ditch opener 2, the grass-sliding roller 1 rotates under the friction of the weeds, thereby pushing the weeds to both sides of the ditch opener 2, thus preventing the weeds from gathering and tangling on the ditch opener 2.
[0033] The grass skiing roller 1 in this solution includes a first roller body 10 and a second roller body 11, and a recessed roller body connection area 111 is formed at the connection between the first roller body 10 and the second roller body 11. When the grass skiing roller 1 rotates, weeds can gather towards the position of the roller body connection area 111 under the guidance of the first roller body 10 and the second roller body 11, avoiding weeds from getting tangled on the entire grass skiing roller 1, thereby facilitating the cleaning of weeds from the grass skiing roller 1.
[0034] Furthermore, the front side of the ditching pear tip 201 is an arc-shaped side 203, with one end of the arc-shaped side 203 extending towards the ground and the other end extending towards the grass skidding roller 1, which can better guide the weeds on the front side of the ditcher 2 onto the grass skidding roller 1.
[0035] Preferably, such as Figure 2 As shown, several grooves 101, recessed towards the inner side of the grass-skimming roller 1, are spaced apart on the outer circumferential surfaces of the first roller body 10 and the second roller body 11. These grooves 101 are arranged along the axial direction of the grass-skimming roller 1, and the spacing between adjacent grooves 101 is consistent. The grooves 101 on the outer circumferential surface of the grass-skimming roller 1 increase the outer circumferential surface area, thereby increasing the contact area between the weeds and the grass-skimming roller 1. This increases the friction between the weeds and the grass-skimming roller 1, enabling more effective rotation of the grass-skimming roller 1 and making it easier for the weeds to slide to both sides, reducing the entanglement of weeds on the grass-skimming roller 1. Furthermore, the grooves 101 are arranged along the axial direction of the grass-skimming roller 1, and their extension shape matches the shape of the outer surface of the first roller body 10 and the second roller body 11, making it easier for the weeds to be guided to the roller body connection area 111.
[0036] In other cases, the outer circumferential surfaces of the first roller body 10 and the second roller body 11 are provided with a plurality of protrusions that extend outward toward the outside of the grass skiing roller 1, and the protrusions are arranged along the axial direction of the grass skiing roller 1, with the intervals between adjacent protrusions being consistent. In this case, the function of the protrusions is the same as that of the groove 101 described above.
[0037] As a further improvement, the first roller body 10 is also connected to the first sliding roller 12, the middle section of which bulges outward toward the outer side of the grass skiing roller 1; the second roller body 11 is also connected to the second sliding roller 13, the middle section of which bulges outward toward the outer side of the grass skiing roller 1. The first sliding roller 12 is also connected to the first recess 112, one end of which is the upper end 102 of the roller body; the second sliding roller 13 is also connected to the second recess 113, one end of which is the lower end 103 of the roller body. Both the upper end 102 and the lower end 103 of the roller body bulge outward toward the outer side of the grass skiing roller 1, forming an arc-shaped end face. Both the first recess 112 and the second recess 113 are recessed inward toward the inner side of the grass skiing roller 1.
[0038] A first sliding roller 12 is provided, and a recessed area is formed at the connection between the first sliding roller 12 and the first roller body 10. A second sliding roller 13 is provided, and a similar recessed area is formed at the connection between the second sliding roller 13 and the second roller body 11. The formation of multiple recessed areas can increase the number of weeds wrapped around the grass-skimming roller 1, reducing the number of times the weeds need to be removed. Furthermore, the first recessed portion 112 and the second recessed portion 113 can also increase the number of weeds wrapped around the grass-skimming roller 1, reducing the number of times the weeds need to be removed. The upper end 102 and the lower end 103 of the roller body have bulging arc-shaped end faces. The lower end 103 of the roller body is connected to the furrow opener 2, and the upper end 102 of the roller body is connected to the seeder. Both the upper end 102 and the lower end 103 of the roller body bulge outwards towards the outside of the grass-skimming roller 1, forming an arc-shaped end face. This reduces the contact area between the two ends of the grass-skimming roller 1 and the furrow opener 2 and the seeder when the grass-skimming roller 1 is connected to the furrow opener 2 and the seeder through its two ends, making the grass-skimming roller 1 easier to rotate by the friction of weeds.
[0039] Because there is a certain gap between the lower end 103 of the grass skidding roller 1 and the furrow opener 2, in order to prevent weeds from tangling and accumulating in this gap, a stop block 202 is connected above the furrow opener 2. The stop block 202 is located on the front side of the grass skidding roller 1, and the side of the stop block 202 facing forward is arc-shaped. Figure 3 As shown, the stop block 202 is positioned close to the grass-skimming roller 1, and its front arc-shaped side faces the weeds during the ditching process, so that the stop block 202 can block the weeds outside the gap between the lower end 103 of the roller body and the ditcher 2.
[0040] Combined Figure 1 As shown, a through hole is opened at the center of the upper end 102 of the roller body above the grass skiing roller 1. One end of the connecting rod 104 is rotatably connected inside the through hole, and the other end of the connecting rod 104 passes through the fixing frame 5, which is fixed to the connecting bracket 4. Adjusting nuts 6 are provided on both sides of the fixing frame 5, and both adjusting nuts 6 are fitted onto the connecting rod 104 to facilitate adjustment of the position of the connecting rod 104 within the grass skiing roller 1. In another configuration, one end of the connecting rod 104 is fixedly connected to the upper end 102 of the roller body, and the other end passes through the fixing frame 5 and is rotatably connected to it.
[0041] This utility model also provides a triangular seeder, including the aforementioned seeder skid, which is connected to the seeder via a connecting bracket 4. Specifically, a fixing frame 5 is connected to the connecting bracket 4, and the upper end of the connecting bracket 4 is connected to the seeder. Furthermore, to prevent the skid roller 1 from wobbling during rotation, connecting legs 3 are respectively provided on both sides of the connecting bracket 4. One end of each connecting leg 3 slides against the side of the skid roller 1 to limit its wobbling.
[0042] In this embodiment, during the furrowing process, the grass-sliding roller 1 can be driven to rotate by the weeds, making it easier for the weeds to be slid away to both sides by the grass-sliding roller 1, thereby preventing the weeds from gathering and tangling on the furrow opener 2. At the same time, more weeds gather in the roller connection area 111, which is convenient for weed cleaning.
[0043] The terms “installation,” “setup,” “equipped with,” and “connection” used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
