Description

Technical Field

[0001] This utility model relates to the field of fertilization and sowing technology, and in particular to a precision variable fertilization and sowing integrated machine. Background Technology

[0002] The fertilizer-seeder integrated machine is a modern agricultural machine that integrates fertilization and sowing functions into one unit. It can simultaneously perform fertilizer application and seed sowing in farmland operations, effectively improving agricultural production efficiency. Through precise control technology, this machine can rationally fertilize and sow according to crop and soil conditions, contributing to the realization of precision agriculture. The precision variable fertilizer-seeder integrated machine is an advanced agricultural machinery device that can not only complete fertilization and sowing work simultaneously, but also precisely control the amount of fertilizer and sowing according to soil fertility and crop growth needs, realizing variable operation and greatly improving the accuracy and efficiency of agricultural production. However, it often needs to be moved during use, which requires the use of mobile equipment.

[0003] Existing mobile equipment includes two types: wheeled and tracked. Wheeled mobile mechanisms typically consist of multiple tires, have a simple structure, low cost, and can travel at high speeds in flat farmland, improving operational efficiency. In large areas of flat farmland, wheeled mobile seeders can quickly shuttle and efficiently complete seeding and fertilization tasks. They are flexible in steering and can adapt to farmland of different shapes, making them easy for drivers to operate. Tracked mobile mechanisms consist of tracks and drive wheels, etc. They have a large ground contact area and low pressure on the ground, allowing them to travel stably on soft, muddy, and uneven land without easily getting stuck, and have strong passability. However, this type of mobility has significant limitations; it cannot adjust the overall width according to the usage scenario, which can lead to the machine damaging the land. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a precision variable fertilization and seeding integrated machine, which aims to improve the limitations of the existing technology in terms of movement mode, which cannot adjust the overall width according to the usage scenario, thus causing the machine to damage the land.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a precision variable fertilization and seeding integrated machine, comprising a frame one, a sliding column slidably connected to the rear end of the frame one, a frame two fixedly connected to the rear end of the sliding column, a cylindrical head fixedly connected to the top of the sliding column, elongated grooves formed on the top of each frame one, the outer wall of the cylindrical head slidably connected to the inner wall of the elongated groove, a connecting column fixedly connected to the front side of the sliding column, a spring slidably connected to the outer wall of the connecting column, the rear end of the spring fixedly connected to the front side of the sliding column, a motor fixedly connected to the rear end of the frame two, a threaded rod fixedly connected to the output end of the motor, a cylindrical sleeve threadedly connected to the rear side of the outer wall of the threaded rod, a crossbar fixedly connected to the middle of the frame one, and a telescopic mechanism provided at the bottom of the frame one for adjusting the height.

[0006] As a further description of the above technical solution:

[0007] The telescopic mechanism includes a connecting rod, the top of which is fixedly connected to the bottom of a crossbar. Multiple threaded holes are provided in the middle of the outer wall of the connecting rod. A bolt is threaded to the inner wall of each threaded hole, and a nut is threaded to the rear end of the outer wall of the bolt. A cylindrical tube is threaded to the front side of the outer wall of the bolt. A threaded hole is provided in the outer wall of the cylindrical tube, and the inner wall of the threaded hole is threaded to the outer wall of the bolt.

[0008] As a further description of the above technical solution:

[0009] A fixed cylinder is fixedly connected near the middle of the second frame, and the inner wall of the fixed cylinder is slidably connected to the outer wall of the threaded rod.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the crossbar has a cylindrical hole, and the inner wall of the cylindrical hole is slidably connected to the outer wall of the cylindrical sleeve.

[0012] As a further description of the above technical solution:

[0013] A connecting plate is fixedly connected to the bottom of the cylindrical tube, and multiple pointed ends are fixedly connected to the right side of the connecting plate.

[0014] As a further description of the above technical solution:

[0015] Multiple connecting cylinders are fixedly connected to the top of each of the frames, and the top of each connecting cylinder is connected to a feed inlet.

[0016] As a further description of the above technical solution:

[0017] An operating chamber is slidably connected to the top of frame one, and the bottom right side of the operating chamber is slidably connected to the top of frame two.

[0018] As a further description of the above technical solution:

[0019] Multiple wheels are fixedly connected to the bottom of each frame, and a seeding port is connected to the bottom of the frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the length needs to be extended, the motor is started, and the threaded rod is rotated. The threaded rod rotates inside the cylindrical sleeve, causing the cylindrical sleeve to rotate outward. The cylindrical sleeve then moves the frame one outward, increasing the gap. The spring on the sliding column moves outward within the long groove of the frame one, causing the sliding column to stretch the spring outward. The spring is stretched and deformed, increasing the gap and enabling the overall width to be adjusted according to the usage scenario and the distance between land plots.

[0022] 2. In this utility model, when the height of the connecting plate needs to be adjusted, first rotate the nut, and then the bolt can be removed. Then, adjust the cylindrical tube with the connecting plate upward and downward. When it is adjusted to a suitable position, rotate the bolt into the threaded hole two and the threaded hole one. Then rotate the nut into the bolt. At this time, the nut and the bolt will be fixed together, thus realizing the function of adjusting the height of the connecting plate. Attached Figure Description

The inner wall of the cylindrical hole 14 is slidably connected to the outer wall of the cylindrical sleeve 11. A connecting plate 15 is fixedly connected to the bottom of the cylindrical cylinder 205, which plays a good role in connection and fixation. Multiple pointed heads 16 are fixedly connected to the right side of the connecting plate 15.

[0036] Specifically, near the center of frame 28, a fixed cylinder 12 is fixedly connected. The inner wall of the fixed cylinder 12 is slidably connected to the outer wall of the threaded rod 10, allowing the threaded rod 10 to rotate and move smoothly within the fixed cylinder 12.

The bottom of frame 1 is also connected to a sowing port 21, through which seeds and other planting materials can be effectively sown into the soil.

[0039] Working principle: When the length needs to be extended, the motor 9 is started, and the motor 9 drives the threaded rod 10 to rotate. The threaded rod 10 rotates inside the cylindrical sleeve 11, causing the cylindrical sleeve 11 to rotate outward. The cylindrical sleeve 11 then moves the frame 1 outward, increasing the gap. The spring 6 on the sliding column 3 moves outward within the long groove 7 of the frame 1, causing the sliding column 3 to stretch the spring 6 outward. The spring 6 is stretched and deformed, increasing the gap. When the gap is too small, the motor 9 is started in the opposite direction. The motor 9 drives the threaded rod 10 to pull the cylindrical sleeve 11 in the opposite direction. The spring 6 is then compressed and restored by the sliding column 3. At this time, the cylindrical head 4 slides within the long groove 7 of the frame 1, realizing the function of adjusting the overall width according to the usage scenario and the size of the land spacing.

[0040] When the height of the connecting plate 15 needs to be adjusted, first rotate the nut 204. At this time, the nut 204 will rotate away from the bolt 203, and then the bolt 203 can be removed. At this time, the bolt 203 will leave the threaded hole 202 on the connecting rod 201 and the threaded hole 206 on the cylindrical tube 205. Then, adjust the cylindrical tube 205 with the connecting plate 15 upward and downward. When it is adjusted to a suitable position, rotate the bolt 203 into the threaded hole 206 and the threaded hole 202. Then rotate the nut 204 into the bolt 203. At this time, the nut 204 and the bolt 203 will be fixed together, realizing the function of adjusting the height of the connecting plate 15.

[0041] 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.
