Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to a grass seed mixing and spreading device. Background Technology

[0002] Grass seed mixing and sowing is a planting technique that involves scientifically mixing different varieties of grass seeds and then using specialized equipment or manual operation to evenly spread the mixed grass seeds over a target area. Since manual sowing is not only labor-intensive but also relatively inefficient, mechanical sowing has become a more common choice. The operation process is usually as follows: first, the mixed grass seeds are loaded into a hopper, and then the screw conveyor at the bottom of the hopper is started to smoothly transport the grass seeds into the conveying pipe; at the same time, the high-speed airflow generated by the blower carries the grass seeds into the trumpet pipe, and under the guiding effect of multiple arc-shaped partitions (42) inside the trumpet pipe, the grass seeds are evenly dispersed and sown on the planting ground.

[0003] However, when sowing at the edge of the field, to prevent grass seeds from being blown out of the planting area by the wind, causing waste or affecting the surrounding environment, a baffle is usually installed on the side of the trumpet tube closest to the edge. While this design can physically confine the grass seeds within the planting area, it also introduces new problems: the grass seeds intercepted by the baffle tend to accumulate in the edge area due to the impact, resulting in a much higher seed density in that area compared to other planting areas. Overly dense grass seeds can cause a series of growth problems, not only inhibiting each other due to competition for water, nutrients, and light, but also potentially increasing the risk of disease due to poor ventilation, ultimately affecting the overall germination rate and growth quality of the grass seeds. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a grass seed mixing and spreading device, which solves the problem of overly dense grass seed spreading in the field edge area.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grass seed mixing and spreading device, comprising:

[0008] A blower, which has a horizontal air outlet;

[0009] The feed pipe is installed at the air outlet of the blower, and the upper end of the feed pipe is installed at the discharge end of the screw conveyor at the bottom of the hopper;

[0010] A conveying pipe is installed at the air outlet of the blower. A horn tube is installed at the end of the conveying pipe away from the blower. The cross-sectional area of ​​the horn tube gradually increases in the direction away from the conveying pipe. Multiple arc-shaped partition plates are evenly installed inside the horn tube.

[0011] A receiving box is located on one side of the horn tube. The side of the receiving box facing the horn tube is open. The receiving box is connected to the conveying pipe through a connector. A strip-shaped opening is provided on the bottom side of the receiving box away from the horn tube. A storage box is provided below the strip-shaped opening. The upper end of the storage box is open and is connected and fixed to the receiving box.

[0012] Preferably, the connector includes:

[0013] Ear plate, which is installed in the middle of the side of the receiving box away from the horn tube;

[0014] The support plate has an L-shaped structure and is connected to the ear plate by fasteners formed by the second screw and the second nut.

[0015] The bracket is provided in two sets, and the two sets of brackets are symmetrically installed on the conveying pipe. The bracket has an L-shaped structure. The end of the support plate away from the ear plate is connected to the bracket by a fastener formed by a first screw and a first nut.

[0016] Preferably, an extension is fixedly connected to the end of the bracket away from the support plate, and the extension is fixedly connected to the conveying pipe.

[0017] Preferably, the end of the support plate away from the ear plate has a first small hole, and the end of the bracket away from the conveying pipe has a second small hole that is aligned with the first small hole. The first screw passes through the channel formed by the first and second small holes and is threadedly connected to a first nut.

[0018] Preferably, a first positioning head is installed at the end of the support plate away from the ear plate, and a first positioning hole is opened at the end of the bracket away from the conveying pipe to cooperate with the first positioning head, and the first positioning head is inserted into the first positioning hole.

[0021] Preferably, the support plate has a first elongated oval opening on one side, and the bracket has a second elongated oval opening on one side.

[0022] Preferably, a guide plate is provided on the side of the strip-shaped opening near the horn tube, the guide plate is installed at the bottom of the receiving box, and the cross-section of the guide plate is an inverted "V" shape.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a grass seed mixing and spreading device, which has the following beneficial effects:

[0025] 1. The collection box on one side of the trumpet-shaped tube features an opening design that effectively intercepts grass seeds near the field edge during sowing, preventing them from splashing outside the planting area. The intercepted seeds fall into the collection box and, guided by an inverted "V"-shaped guide plate, flow through a strip-shaped opening into a storage box for temporary storage. Compared to traditional baffles that directly block the flow and cause accumulation at the field edge, this structure collects excess grass seeds through recycling. The seeds can then be manually removed from the storage box and added back to the hopper for reuse, fundamentally avoiding the problem of excessively high grass seed density at the field edge. This ensures even distribution of grass seeds throughout the planting area and reduces the risks of nutrient competition and disease proliferation caused by dense growth.

[0026] 2. The collection box is connected to the conveying pipe through a connector consisting of ear plates, support plates, and brackets. It can be quickly assembled and disassembled with fasteners such as the first screw and the second screw. When it is not necessary to spread the grass at the edge of the field, the collection box can be removed to avoid unnecessary interception. At the same time, the collection box can be installed on one side of the trumpet pipe as needed, so that the collection box only intercepts grass seeds on the edge side of the field and does not affect the normal spreading in other directions of the trumpet pipe. This ensures uniform coverage of the central area and solves the boundary control problem at the edge of the field, which is especially suitable for edge treatment of regular plots.

[0027] 3. The first positioning head is inserted into the first positioning hole, and the second positioning head is inserted into the second positioning hole. Thus, the first positioning head and the first screw cooperate with each other to restrict the relative position of the bracket and the support plate. The second positioning head and the second screw cooperate with each other to restrict the relative position of the support plate and the ear plate. Only one first screw and one second screw are needed, thereby reducing the number of fasteners to be disassembled and assembled. Attached Figure Description

[0041] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0042] This utility model provides a technical solution:

[0043] Please see Figures 1-3 A grass seed mixing and spreading device includes a blower 1 with a horizontal air outlet 11. A feed pipe 2 is installed at the air outlet 11 of the blower 1, and the upper end of the feed pipe 2 is installed at the discharge end of a screw conveyor at the bottom of the hopper. A conveying pipe 4 is installed at the air outlet 11 of the blower 1. A trumpet pipe 41 is installed at the end of the conveying pipe 4 away from the blower 1. The cross-sectional area of ​​the trumpet pipe 41 gradually increases in the direction away from the conveying pipe 4. Multiple arc-shaped partition plates 42 are evenly installed inside the trumpet pipe 41. First, the mixed grass seeds are loaded into the hopper, and the screw conveyor at the bottom of the hopper is then started to smoothly convey the grass seeds into the conveying pipe 4. At the same time, the blower 1 starts to operate, and the high-speed airflow generated will carry the grass seeds in the conveying pipe 4 into the trumpet pipe 41. The multiple arc-shaped partition plates 42 evenly installed inside the trumpet pipe 41 play a guiding and dispersing role on the airflow and grass seeds, so that the grass seeds are evenly spread on the ground of the planting area under the drive of the airflow.

[0044] See Figures 1-4The receiving box 5 is located on one side of the horn tube 41. The side of the receiving box 5 facing the horn tube 41 is open. A strip-shaped opening 51 is opened at the bottom of the receiving box 5, away from the horn tube 41. A storage box 53 is located below the strip-shaped opening 51. The upper end of the storage box 53 is open and is connected and fixed to the receiving box 5. A guide plate 52 is located on the side of the strip-shaped opening 51 near the horn tube 41. The guide plate 52 is installed at the bottom of the receiving box 5 and has an inverted "V" shaped cross-section. The receiving box 5 on the side of the horn tube 41 has an open design, which can intercept grass seeds near the edge of the ground during sowing and prevent grass seeds from splashing outside the planting area. After the intercepted grass seeds fall into the receiving box 5, they are guided by the inverted "V" shaped guide plate 52 and enter the storage box 53 through the strip-shaped opening 51 for temporary storage. Unlike traditional methods that use barriers to directly block grass seeds, leading to their accumulation at the field edges, this structure collects excess grass seeds through recycling. The seeds can then be manually removed from the storage box 53 and added back to the hopper for reuse. This design fundamentally solves the problem of excessive grass seed density at field edges, ensuring even distribution of grass seeds throughout the planting area and reducing the risks of nutrient competition and disease proliferation caused by dense grass growth.

[0045] See Figures 1-3 The ear plate 54 is installed in the middle of the side of the receiving box 5 away from the horn tube 41. The support plate 6 has an L-shaped structure and is connected to the ear plate 54 by fasteners formed by the second screw 8 and the second nut 81. The support plate 6 has a first elongated oval opening 61 on one side. There are two sets of brackets 3, which are symmetrically installed on the conveying pipe 4. The brackets 3 have an L-shaped structure and a second elongated oval opening 31 on one side. The end of the support plate 6 away from the ear plate 54 is connected to the bracket 3 by fasteners formed by the first screw 7 and the first nut 71. The end of the bracket 3 away from the support plate 6 is connected and fixed with an extension part 33, so that the extension part 33 is connected and fixed to the conveying pipe 4, which increases the connection range between the bracket 3 and the conveying pipe 4. The receiving box 5 is connected to the conveying pipe 4 through the connector composed of the ear plate 54, the support plate 6 and the bracket 3. The fasteners such as the first screw 7 and the second screw 8 can be used to achieve quick disassembly and installation. When sowing is carried out in non-edge areas, the collection box 5 can be easily removed to avoid unnecessary interception of grass seeds; when boundary control is required at the edge, the collection box 5 can be installed on the corresponding side of the horn tube 41 according to actual needs.

[0046] In this way, the collection box 5 will only intercept grass seeds on the side closest to the edge of the field, without interfering with the normal sowing of grass seeds in other directions by the horn tube 41. This ensures uniform coverage in the middle area of ​​the planting area and effectively solves the problem of grass seed boundary control at the edge of the field. It is especially suitable for edge sowing treatment of regular plots, such as farmland and lawns.

[0047] See Figures 1-4The support plate 6 has a first small hole at the end away from the ear plate 54, and the bracket 3 has a second small hole at the end away from the conveying pipe 4, which is aligned with the first small hole. The first screw 7 passes through the channel formed by the first and second small holes and is threaded with a first nut 71. A first positioning head 62 is installed at the end of the support plate 6 away from the ear plate 54, and a first positioning hole 32 is provided at the end of the bracket 3 away from the conveying pipe 4, which mates with the first positioning head 62. A third small hole is provided on the side of the support plate 6 facing the ear plate 54, and a fourth small hole is provided on the side of the ear plate 54 facing the support plate 6, which is aligned with the third small hole. One end of the second screw 8... A second nut 81 is threaded through the third and fourth small holes and connected to the second nut 81. A second positioning head 63 is installed on the side of the support plate 6 facing the ear plate 54. A second positioning hole 55 is opened on the side of the ear plate 54 facing the support plate 6 to cooperate with the second positioning head 63. The first positioning head 62 is inserted into the first positioning hole 32, and the second positioning head 63 is inserted into the second positioning hole 55. Through the cooperation of the first positioning head 62 and the first screw 7, the relative position between the bracket 3 and the support plate 6 can be restricted; through the cooperation of the second positioning head 63 and the second screw 8, the relative position between the support plate 6 and the ear plate 54 can be restricted. This design only requires one first screw 7 and one second screw 8 to achieve a stable connection of each component, greatly reducing the number of fasteners that need to be operated during the assembly and disassembly process, making the assembly and disassembly of the equipment more convenient and efficient.

[0048] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
