Description

Technical Field

[0001] This utility model relates to the field of corn planting machine technology, and in particular to a corn planting machine with adjustable spacing. Background Technology

[0002] A corn planter is a planting machine that sows corn seeds. Planters are often named after the crop they are used for, such as corn planter, grain row planter, corn hill planter, cotton planter, and timber broadcaster. Corn planters are characterized by uniform sowing depth, stable row spacing, good soil covering, seed saving, and high work efficiency.

[0003] Traditional corn planters mainly consist of a frame, seed box, seed metering device (mostly spoon-type or mortise wheel type), furrow opener (fixed-angle plow shovel), soil covering device (flat plate or disc), transmission mechanism (chain or gear) and walking wheels. When working, the furrow opener opens the furrow and the seeds fall into the furrow, and the soil covering device covers the seeds.

[0004] However, the furrowing angle, height, and spacing of traditional planting machines are mostly fixed or cumbersome to adjust, making it difficult to adapt to the different requirements of different soils such as clay and sand for furrowing parameters. They also cannot flexibly meet the row spacing requirements of different corn varieties, resulting in poor furrowing quality and low adaptability. At the same time, the water supply device of traditional equipment lacks precise control, the nozzles are easily damaged by soil debris when idle, and water volume monitoring is inconvenient, affecting the water supply effect and equipment lifespan, making it difficult to meet the needs of large-scale and refined corn planting.

[0005] Therefore, an adjustable-spacing corn planter is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a corn planting machine with adjustable spacing, which aims to improve the problems of inconvenient adjustment of furrowing parameters and row spacing, and easy damage of nozzles in the existing traditional corn planting machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-spacing corn planter, comprising a base, a fixed seat on the upper side of the base, a support column slidably connected inside the fixed seat, a furrowing plow fixedly connected to the lower side of the support column, an L-shaped plate fixedly connected to the outer side of the support column, a limit groove inside the fixed seat, a spring fixedly connected inside the fixed seat, a locking block fixedly connected to the side of the spring away from the fixed seat, a pull block fixedly connected to the upper side of the locking block, a locking groove inside the L-shaped plate, cylinders at the four outer corners of the fixed seat, rotating seats rotatably connected to the telescopic ends of the cylinders, the rotating seats fixedly connected to the four outer corners of the fixed seat, and a spraying assembly on the right side of the furrowing plow.

[0008] Furthermore, the spraying assembly includes a water storage tank, which is fixedly connected to the upper side of the base. A water pump is fixedly connected to the left side of the water storage tank. A spraying base is fixedly connected to the lower side of the base. An atomizing nozzle is fixedly installed on the lower side of the spraying base. The spraying base is fixedly connected to the water pump. An electric actuator is fixedly installed on the right side of the spraying base. A protective cover is fixedly connected to the telescopic end of the electric actuator.

[0009] Furthermore, the L-shaped plate is slidably connected inside the limiting groove, and the locking block is slidably connected inside the locking groove.

[0010] Furthermore, the protective cover is slidably connected to the right side of the sprayer.

[0011] Furthermore, the fixed seat is rotatably connected to the upper side of the base.

[0012] Furthermore, an observation window is fixedly installed inside the water storage tank.

[0013] Furthermore, rollers are fixedly connected to the four lower corners of the base.

[0014] Furthermore, a controller is fixedly installed on the front side of the water storage tank, and the controller is electrically connected to the water pump.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the angle and height of the furrowing plow are adjusted by a cylinder to adapt to different soil furrowing needs; the sliding support column and locking block enable rapid adjustment of the spacing to meet the row spacing requirements of different corn varieties, thereby improving the planter's adaptability to soil and varieties and ensuring standardized furrowing.

[0017] In this invention, precise water replenishment through atomizing nozzles facilitates seed germination, while an observation window monitors water volume in real time. When not in use, an electric actuator pushes a protective cover to protect the nozzles, reducing damage, ensuring the quality of trenching and water replenishment, and improving planting efficiency and equipment durability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 An embodiment of this utility model provides: an adjustable spacing corn planting machine, including a base 1, a fixed seat 3 on the upper side of the base 1, a support column 4 slidably connected inside the fixed seat 3, a furrowing plow 13 fixedly connected to the lower side of the support column 4, an L-shaped plate 5 fixedly connected to the outer side of the support column 4, a limit groove 6 opened inside the fixed seat 3, a spring 8 fixedly connected inside the fixed seat 3, a locking block 7 fixedly connected to the side of the spring 8 away from the fixed seat 3, a pull block 9 fixedly connected to the upper side of the locking block 7, a locking groove 12 opened inside the L-shaped plate 5, the L-shaped plate 5 slidably connected to the inside of the limit groove 6, the locking block 7 slidably connected to the inside of the locking groove 12, cylinders 10 are provided at the four outer corners of the fixed seat 3, rotating seats 11 are rotatably connected to the telescopic ends of the cylinders 10, the rotating seats 11 are fixedly connected to the four outer corners of the fixed seat 3, the fixed seat 3 is rotatably connected to the upper side of the base 1, and rollers 2 are fixedly connected to the four lower corners of the base 1;

[0027] Specifically, the rollers 2 contact the ground, moving the entire machine to the designated planting area. By activating the cylinders 10 at the four corners of the fixed base 3, the extension and retraction of the cylinders 10 cause the fixed base 3 to rotate around the base 1 via the rotating seat 11. When the fixed base 3 rotates, it causes the support column 4 and the furrowing plow 13 to rotate synchronously, thus adjusting the angle of the furrowing plow 13 into the soil. Simultaneously, the extension and retraction of the cylinders 10 causes the support column 4 to slide up and down within the fixed base 3, adjusting the height of the support column 4 and thus changing the depth of the furrowing plow 13 into the soil to meet the requirements of different soil textures (such as clay and sand) for furrowing angle and depth. Through the extension and retraction of the cylinders 10, the machine achieves… The ditching plow 13 allows for flexible adjustment of its angle and height to adapt to various field soil conditions. When it is necessary to adjust the spacing between the ditching plows 13, pulling the pull block 9 causes the locking block 7 to compress the spring 8 and disengage from the slot 12 of the L-shaped plate 5, releasing the lock on the support column 4. The support column 4 then slides horizontally within the fixed seat 3, allowing the L-shaped plate 5 to move along the limiting groove 6 to the designated position. After releasing the pull block 9, the spring 8 within the fixed seat 3 rebounds and pushes the locking block 7 back into the slot 12 of the L-shaped plate 5, locking the position of the support column 4. Through the sliding of the support column 4 and the locking of the locking block 7, the spacing of the ditching plows 13 can be quickly adjusted to adapt to the planting row spacing requirements of different corn varieties.

[0028] Reference Figure 1 and Figure 5 A spraying assembly 14 is provided on the right side of the ditching plow 13. The spraying assembly 14 includes a water storage tank 141, which is fixedly connected to the upper side of the base 1. An observation window 16 is fixedly installed inside the water storage tank 141. A water pump 142 is fixedly connected to the left side of the water storage tank 141. A spraying seat 143 is fixedly connected to the lower side of the base 1. An atomizing nozzle 144 is fixedly installed on the lower side of the spraying seat 143. The spraying seat 143 is fixedly connected to the water pump 142. An electric actuator 145 is fixedly installed on the right side of the spraying seat 143. A protective cover 146 is fixedly connected to the telescopic end of the electric actuator 145. The protective cover 146 is slidably connected to the right side of the spraying seat 143. A controller 15 is fixedly installed on the front side of the water storage tank 141. The controller 15 is electrically connected to the water pump 142.

[0029] Specifically, the controller 15 starts the water pump 142, which draws water from the water storage tank 141 and transports it through a pipeline to the spraying base 143. After the water is collected in the spraying base 143, it is evenly sprayed into the trench and surrounding soil in the form of atomizing nozzles 144 on the lower side. The observation window 16 inside the water storage tank 141 can be used to observe the remaining water volume in real time. Through the coordinated work of the water pump 142 and the atomizing nozzles 144, precise watering of the soil after trenching is achieved, which is beneficial to subsequent seed germination. When the atomizing nozzles 144 are not in use, the electric actuator 145 is activated. The telescopic end of the electric actuator 145 pushes the protective cover 146 to slide along the spraying base 143 until the spraying base 143 and the atomizing nozzles 144 are completely locked into the protective cover 146. The protective cover 146 protects the atomizing nozzles 144 from damage by soil and debris when idle.

[0030] Working principle: When using this device, the roller 2 moves the device to the designated area. By activating the cylinder 10, the cylinder 10 extends and retracts, pushing the fixed seat 3 to rotate through the rotating seat 11, thereby adjusting the angle of the ditching plow 13. At the same time, the cylinder 10 can also adjust the height of the support column 4 to meet the ditching needs of different soils. When it is necessary to adjust the spacing between the ditching plows 13, the support column 4 is slid in the fixed seat 3, and the L-shaped plate 5 is inserted into the designated limiting groove 6. After adjustment, the spring 8 in the fixed seat 3 pushes the locking block 7 into the locking groove 12 of the L-shaped plate 5, locking the position of the support column 4. When readjustment is required, the pull block 9 is pulled to disengage the locking block 7 from the locking groove 12.

[0031] During trenching, the trenching plow 13 moves forward with the equipment and cuts into the soil to form a trench; the controller 15 starts the water pump 142, which sprays water from the water storage tank 141 through the spray seat 143 and the atomizing nozzle 144 into the trench. The observation window 16 can monitor the water level; when the atomizing nozzle 144 is not in use, the electric push rod 145 is activated, which pushes the protective cover 146 to slide, locking the spray seat 143 and the atomizing nozzle 144 into the protective cover 146 to protect the atomizing nozzle 144.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
