Corn planting row spacing adjustment mechanism

Abstract

This utility model discloses a corn planting row spacing adjustment mechanism, which includes a suspended support frame disposed on the back of two corn planters. A wheel assembly is mounted on the front of the suspended support frame, located between the two corn planters. A limiting groove is fixedly connected to the top of the suspended support frame, and two symmetrical limiting slide rails are fixedly connected to the surface of the limiting groove. This utility model simultaneously activates two servo electric cylinders, causing the output ends of the servo electric cylinders to push a connecting plate in linear motion. This causes the connecting plate to push a slider in linear motion on the surface of the limiting slide rails, thereby causing the two sliders to move in opposite directions. This, in turn, causes the two connecting plates to move in opposite directions, which in turn drive the two corn planters to move in opposite directions via the fixed plate. By adjusting the spacing between the two corn planters, the row spacing of corn planting can be adjusted through the combined use of cylinders, limiting guide rails, and sliders, thus adapting to different corn planting needs.

Description

Technical Field

[0001] This utility model belongs to the field of corn planting technology, and in particular relates to a corn planting row spacing adjustment mechanism. Background Technology

[0002] Corn planters are a type of agricultural planting machinery that replaces traditional manual planting with mechanized methods. They are suitable for large-scale farmland operations and their design must be combined with the growth characteristics of corn crops. They are important equipment for modern agriculture to achieve precision planting and increase yields, and are generally mounted on agricultural machinery.

[0003] With the increasing variety of corn varieties, different varieties have different requirements for planting row spacing. Furthermore, differences in soil fertility and climate conditions are also important factors affecting the differences in corn planting row spacing. Currently, the planting boxes of most corn planters are relatively fixed or require manual disassembly of the planting box to adjust the planting spacing. Therefore, a corn planting row spacing adjustment mechanism is needed, which can adjust the corn planting row spacing through the cooperation of cylinders, limit guide rails, and sliders, thereby adapting to different corn planting needs. Utility Model Content

[0004] The purpose of this invention is to provide a corn planting row spacing adjustment mechanism, which can adjust the corn planting row spacing through the cooperation of a cylinder, a limit guide rail, and a slider, thereby adapting to different corn planting needs and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a corn planting row spacing adjustment mechanism, which includes a suspended support frame disposed on the back of two corn planters; a wheel assembly is installed on the front of the suspended support frame, the wheel assembly is located between the two corn planters, a limit groove is fixedly connected to the top of the suspended support frame, two symmetrical limit slide rails are fixedly connected to the surface of the limit groove, a slider is slidably connected to the surface of the limit slide rail, a connecting plate is fixedly connected to the top of the slider, an mounting plate is disposed between the two limit slide rails, the bottom of the mounting plate is fixedly connected to the limit groove, a servo electric cylinder is fixedly installed on the top of the mounting plate, the output end of the servo electric cylinder is fixedly connected to the connecting plate, a fixing plate is fixedly connected to the front of the connecting plate, and the fixing plate is fixedly connected to the corn planter.

[0006] Preferably, the front of the suspended support frame is fixedly connected to two symmetrical limiting plates, and a limiting slide rod is fixedly connected between the two limiting plates.

[0007] Preferably, the back of the connecting plate is provided with two rectangular plates, the rectangular plates are fixedly connected to the fixing plate, and the limiting slide rod passes through the rectangular plates and is slidably connected to the rectangular plates.

[0008] Preferably, a cover plate is installed on the top of the limiting groove, and the two rectangular plates are located on the left and right sides of the fixing plate.

[0009] Preferably, the limiting slide rail is an I-shaped limiting slide rail, and the fixing plate is a U-shaped right-angle plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model simultaneously activates two servo electric cylinders, causing the output ends of the servo electric cylinders to push the connecting plate to move linearly. This causes the connecting plate to push the slider to move linearly on the surface of the limit rail, thereby causing the two sliders to move in opposite directions. This causes the two connecting plates to move in opposite directions, and the two connecting plates, through the fixed plate, drive the two corn planters to move in opposite directions. This allows for adjustment of the distance between the two corn planters. The travel distance of the output ends of the two servo electric cylinders is the planting row spacing. This achieves the purpose of adjusting the corn planting row spacing through the cooperation of cylinders, limit rails, and sliders, thus adapting to different corn planting needs.

[0012] 2. This utility model uses the combination of a limiting plate, a limiting slide bar, and a rectangular plate. When two servo electric cylinders push two fixed plates to move in opposite directions through the connecting plate, the rectangular plate is fixedly connected to the fixed plate. Therefore, the fixed plate is limited by the limiting plate, which causes the rectangular plate to slide on the surface of the rectangular plate, thereby improving the stability of the two corn planters when adjusting the spacing.

[0020] In the following description, embodiments of the corn planting row spacing adjustment mechanism of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a corn planting row spacing adjustment mechanism according to an embodiment of the present invention. It includes a suspended support frame 2 mounted on the back of two corn planters 1. A wheel assembly 3 is mounted on the front of the suspended support frame 2. Two symmetrical limiting plates 11 are fixedly connected to the front of the suspended support frame 2. Through the cooperation of the limiting plates 11, limiting slide rods 12, and rectangular plates 13, when two servo electric cylinders 9 push two fixed plates 10 to move in opposite directions via a connecting plate 7, the rectangular plates 13 are fixedly connected to the fixed plates 10. Therefore, the fixed plates 10 are limited by the limiting plates 11, causing the rectangular plates 13 to slide on the surface of the rectangular plates 13, thereby improving the stability of the two corn planters 1 when adjusting the spacing. A limiting slide rod 12 is fixedly connected between the two limiting plates 11. The wheel assembly 3 is located between the two corn planters 1. A limiting groove 4 is fixedly connected to the top of the suspended support frame 2. A cover plate 14 is installed on the top of the limiting groove 4. Two rectangular plates 13 are located on the left and right sides of the fixing plate 10. Two symmetrical limiting slide rails 5 are fixedly connected to the surface of the limiting groove 4. The limiting slide rails 5 are I-shaped limiting slide rails. The fixing plate 10 is a U-shaped right-angle plate. A slider 6 is slidably connected to the surface of the limiting slide rail 5. A connecting plate 7 is fixedly connected to the top of the slider 6. Two rectangular plates 13 are provided on the back of the connecting plate 7. The rectangular plates 13 are fixedly connected to the fixing plate 10. The limiting slide rod 12 passes through the rectangular plates 13 and is slidably connected to the rectangular plates 13. An installation plate 8 is provided between the two limiting slide rails 5. The bottom of the installation plate 8 is fixedly connected to the limiting groove 4. A servo electric cylinder 9 is fixedly installed on the top of the installation plate 8. The output end of the servo electric cylinder 9 is fixedly connected to the connecting plate 7. The front of the connecting plate 7 is fixedly connected to the fixing plate 10. The fixing plate 10 is fixedly connected to the corn planter 1.

[0022] Working Principle: When using this utility model, the user simultaneously activates two servo electric cylinders 9, causing the output ends of the servo electric cylinders 9 to push the connecting plate 7 to move linearly. Since the connecting plate 7 is fixedly connected to the slider 6, and the slider 6 is slidably connected on the surface of the limiting slide rail 5, the connecting plate 7 pushes the slider 6 to move linearly on the surface of the limiting slide rail 5 through the limiting slide rail 5. This causes the two sliders 6 to move in opposite directions, thereby causing the two connecting plates 7 to move in opposite directions. Since the fixed plate 10 is fixedly connected to the connecting plate 7 and also fixedly connected to the corn planter 1, the two connecting plates 7 drive the two corn planters 1 to move in opposite directions through the fixed plate 10, thereby adjusting the distance between the two corn planters 1. The travel distance of the output ends of the two servo electric cylinders 9 is the planting row spacing. In this way, the row spacing of corn planting can be adjusted by the cooperation of the cylinders, limiting guide rails, and sliders, thus adapting to different corn planting needs.

[0023] In summary, this corn planting row spacing adjustment mechanism adjusts the spacing by simultaneously activating two servo electric cylinders 9. The output of each servo electric cylinder 9 pushes a connecting plate 7 in a linear motion, which in turn pushes a slider 6 on the surface of a limit rail 5. This causes the two sliders 6 to move in opposite directions, which in turn causes the two connecting plates 7 to move in opposite directions. The two connecting plates 7, through a fixed plate 10, drive the two corn planters 1 to move in opposite directions, thus adjusting the spacing between the two corn planters 1. The travel distance of the output of the two servo electric cylinders 9 is the planting row spacing. Therefore, the corn planting row spacing can be adjusted through the combined use of cylinders, limit rails, and sliders to meet different corn planting needs.
