Description

Technical Field

[0001] This utility model belongs to the technical field of seeding and fertilizing machines, and particularly relates to a hand-held adaptive seeding and fertilizing machine. Background Technology

[0002] With the continuous improvement of modern agricultural mechanization, seeders and fertilizer applicators, as one of the important agricultural machines, play a crucial role in the grain planting process. Traditional seeders and fertilizer applicators mainly use fixed seeding devices and fertilization systems to evenly apply seeds and fertilizers to the soil.

[0003] In traditional seeder-fertilizer machines, the seeding and fertilization processes are typically achieved through fixed guide plates or chassis structures. These guide plates or chassis are usually designed based on fixed parameters, so in practical applications, they may not be able to adequately adapt to various terrains and tillage conditions as soil type, water depth, and crop variety change. Especially in some loose or heavy clay soils, the operating efficiency of existing equipment will be significantly affected, and in severe cases, it may cause uneven soil tillage or fertilizer waste. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A walk-behind adaptive seeder and fertilizer applicator includes a walk-behind tractor, a mounting frame mounted on the walk-behind tractor, and a connecting plate fixedly connected to the mounting frame. The walk-behind adaptive seeder and fertilizer applicator also includes:

[0006] A sowing and fertilizing mechanism, which is used for sowing and fertilizing, and is fixed to a connecting plate by a connector;

[0007] A mud guiding mechanism includes a mud guiding plate, and an adjustment mechanism is provided between the mud guiding plate and the connecting plate. The adjustment mechanism includes a first hinge member provided on the connecting plate and a second hinge member provided on the mud guiding plate. A first threaded rod is fixedly connected to the first hinge member, and a second threaded rod is fixedly connected to the second hinge member. A spiral threaded sleeve is threaded on both the first threaded rod and the second threaded rod.

[0008] As a preferred embodiment of the above technical solution, the first threaded rod and the second threaded rod are located on the same axis and have opposite thread directions.

[0009] As a preferred embodiment of the above technical solution, the connector includes a U-shaped frame and an L-shaped connecting frame, the U-shaped frame being fixedly connected to the connecting plate, and the L-shaped connecting frame being fixedly connected between the U-shaped frame and the sowing and fertilizing mechanism.

[0010] As a preferred embodiment of the above technical solution, the mud guiding mechanism further includes a shaft above the mud guiding plate, and a fixing plate is fixedly connected between the mud guiding plate and the shaft.

[0011] As a preferred embodiment of the above technical solution, a transition plate is rotatably sleeved around the shaft, and the other end of the transition plate is fixed to the outer wall of the sowing and fertilizing mechanism.

[0012] As a preferred embodiment of the above technical solution, a bearing is fixedly inserted through the end of the adapter strip away from the sowing and fertilizing mechanism, and the inner ring of the bearing is fixedly sleeved on the outer periphery of the shaft.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a conventional walking tractor. By installing a frame, connecting plates, and connecting parts, the sowing and fertilizing mechanism can be connected to the walking tractor. Compared with other sowing and fertilizing machines, this utility model is more in line with the usage habits of agricultural workers and reduces the difficulty of operation and learning for agricultural workers.

[0015] 2. This utility model, by rotating the spiral thread assembly, can drive the mud guide plate in the mud guide mechanism to deflect around the shaft rod in an angle under the threaded connection of the spiral thread assembly and the first and second thread rods. This allows for real-time adjustment according to the actual field conditions, water depth, and other conditions, making it fully adaptable to various terrains and farming conditions, and avoiding uneven soil tillage or fertilizer waste.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figures 1-3 As shown, the walk-behind adaptive seeder and fertilizer applicator includes a walk-behind tractor 10, a mounting frame 11 on the walk-behind tractor 10, and a connecting plate 20 fixedly connected to the mounting frame 11. The walk-behind adaptive seeder and fertilizer applicator also includes:

[0023] The sowing and fertilizing mechanism 40 is used for sowing and fertilizing. The sowing and fertilizing mechanism 40 and the connecting plate 20 are fixed together by the connecting piece 30.

[0024] This utility model uses a conventional walking tractor 10. The sowing and fertilizing mechanism 40 can be connected to the walking tractor 10 through the installation frame 11, connecting plate 20, connecting parts 30 and other connecting parts. Compared with other sowing and fertilizing machines, this utility model is more in line with the usage habits of agricultural workers and reduces the difficulty of operation and learning for agricultural workers.

[0025] The mud guiding mechanism 80 includes a mud guiding plate 81. An adjustment mechanism is provided between the mud guiding plate 81 and the connecting plate 20. The adjustment mechanism includes a first hinge 51 on the connecting plate 20 and a second hinge 52 on the mud guiding plate 81. A first threaded rod 61 is fixedly connected to the first hinge 51, and a second threaded rod 62 is fixedly connected to the second hinge 52. A spiral threaded sleeve 70 is threaded on both the first threaded rod 61 and the second threaded rod 62. The mud guiding mechanism 80 also includes a shaft 82 above the mud guiding plate 81. A fixing plate 83 is fixedly connected between the mud guiding plate 81 and the shaft 82. A transition plate 84 is rotatably sleeved on the outer periphery of the shaft 82. The other end of the transition plate 84 is fixed to the outer wall of the sowing and fertilizing mechanism 40. A bearing is fixedly inserted through the end of the transition plate 84 away from the sowing and fertilizing mechanism 40, and the inner ring of the bearing is fixedly sleeved on the outer periphery of the shaft 82.

[0026] This utility model, by rotating the spiral threaded assembly 70, can drive the mud guide plate 81 in the mud guide mechanism 80 to deflect around the shaft 82 in real time under the threaded connection transmission between the spiral threaded assembly 70 and the first threaded rod 61 and the second threaded rod 62. This allows for real-time adjustment according to the actual field conditions, water depth, etc., so that it can fully adapt to various terrains and farming conditions, avoiding uneven soil tillage or fertilizer waste.

[0027] The first threaded rod 61 and the second threaded rod 62 are located on the same axis and have opposite thread directions. In this utility model, locating the first threaded rod 61 and the second threaded rod 62 on the same axis facilitates the installation of the spiral threaded assembly 70, ensuring that the first threaded rod 61, the spiral threaded assembly 70, and the second threaded rod 62 are all located on the same axis; the opposite thread directions allow the first threaded rod 61 and the second threaded rod 62 to move closer to or further away from each other when the spiral threaded assembly 70 is rotated.

[0028] The connector 30 includes a U-shaped frame 31 and an L-shaped connecting bracket 32. The U-shaped frame 31 is fixedly connected to the connecting plate 20, and the L-shaped connecting bracket 32 ​​is fixedly connected between the U-shaped frame 31 and the sowing and fertilizing mechanism 40. In this embodiment, the connector 30 uses a U-shaped frame 31 and an L-shaped connecting bracket 32. In practical applications, the U-shaped frame 31 and the L-shaped connecting bracket 32 ​​can be replaced with other connecting components with the same function.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
