Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural machinery technology, and in particular to a corn field planter with adjustable plant spacing. Background Technology
[0002] The spacing between corn plants has a significant impact on corn growth and yield. Plant spacing refers to the distance between two adjacent corn plants in the same row. The spacing needs to be determined based on factors such as corn variety, soil fertility, climate conditions, planting density, and planting techniques.
[0003] Generally, the plant spacing for corn is usually between 25 and 30 centimeters. However, under certain specific planting conditions, the plant spacing may be adjusted. For example, under high-fertility soil conditions, the plant spacing can be controlled at around 20 to 25 centimeters to increase corn yield; while under low-fertility soil conditions, the plant spacing is generally controlled at around 30 to 35 centimeters to ensure the quality of corn growth.
[0004] Currently, there are specialized equipment such as precision seeders and automated plant protection machines that can precisely control the quantity and position of seeds to achieve consistent plant spacing. However, such equipment is often expensive to manufacture and maintain, and is suitable for large-scale sowing operations. It is usually not affordable for small-scale sowing, which is usually done manually. Manual sowing is less efficient and can easily lead to large deviations in plant spacing, affecting the normal growth of corn. Utility Model Content

[0039] See Figure 1-6 An adjustable-spacing corn field planter includes:
[0040] The frame 1 is made of galvanized square tubing and has a square structure. A connector 11 is provided at the front end of the frame 1. The frame 1 can be fixed to the rear of an external power equipment, such as a tractor or a walking tractor, through the connector 11. The external power equipment can drive the device forward to sow corn. Furthermore, to improve the stability of the connection, a reinforcing frame 12 is also welded and fixed on the frame 1.
[0041] The ditching mechanism 2 is installed at the front end of the frame 1. It can create planting furrows on cultivated land. The ditching mechanism 2 includes a connecting block 21, a first locking buckle 22, a sliding rod 23, fixing bolts 24, and a ditching disc 25. The connecting block 21 is slidably connected to the frame 1. During installation, the row spacing can be adjusted by sliding the connecting block 21 left and right. After adjustment, the connecting block 21 is fixed to the frame 1 by the first locking buckle 22. A sliding rod 23 is vertically slidably connected to the connecting block 21. The ditching disc 25 is rotatably mounted at the bottom of the sliding rod 23. By sliding the sliding rod 23 up and down, the height of the ditching disc 25 can be adjusted, thereby controlling the ditching depth. A fixing bolt 24 corresponding to the sliding rod 23 is also threaded onto the connecting block 21. Furthermore, two ditching discs 25 are provided, arranged in a V-shape, with their pointed ends facing the front of the frame 1 in the direction of movement, facilitating soil breaking.
[0042] The sowing mechanism 3 is installed behind the furrowing mechanism 2 and corresponds one-to-one with it. The sowing mechanism 3 includes a rotating shaft 32, a motor 35, a seed box 36, and a sowing wheel 37. A bracket 31 is fixedly installed on the frame 1. The seed box 36 is fixedly installed on the bracket 31 with bolts and nuts, and the seed box 36 is aligned with the furrowing disc 25 to facilitate sowing. The sowing wheel 37 is rotatably installed at the bottom of the seed box 36. The sowing wheel 37 has a groove 371 for quantitatively loading seeds. The size of the groove 371 can be adjusted according to needs. Generally, 2-3 corn seeds can be loaded into the groove 371 at a time. The rotating shaft 32 is rotatably installed on the bracket 31 and is fixedly connected to the sowing wheel 37. The rotating shaft 32 can drive the sowing wheel 37 to rotate. A motor 35 for driving the rotating shaft 32 is also fixedly installed on the frame 1. The motor 35 is a speed-regulating motor. By controlling the speed of the motor 35, the speed of the rotating shaft 32 is controlled, thereby controlling the sowing spacing.
[0043] Furthermore, the bottom of the seed box 36 has a feed inlet 361 corresponding to the sowing wheel 37, and a baffle 38 is slidably connected to the feed inlet 361. The feed inlet 361 can be closed or opened by sliding the baffle 38. A first gear 33 is fixedly connected to the end of the rotating shaft 32, and a second gear 34 meshing with the first gear 33 is fixedly connected to the output shaft of the motor 35. In use, corn seeds fall from the feed inlet 361 into the groove 371 of the sowing wheel 37 under the action of gravity. The motor 35 drives the rotation of the sowing wheel 37. When the groove 371 faces downward, the seeds fall out from the discharge port 362 under the action of gravity and fall into the seed furrow, completing the sowing. Furthermore, during sowing, by controlling the external power equipment to drive the frame 1 forward at a constant speed, the rotation speed of the motor 35 can be adjusted to change the time required for the sowing wheel 37 to rotate one revolution, thereby changing the sowing frequency and adjusting the sowing spacing.
[0044] The soil covering tray 4 is installed on the rear side of the sowing mechanism 3. The soil covering tray 4 can cover the seed furrow with soil. Specifically, there are two soil covering trays 4 arranged in a figure-eight shape, with the larger opening facing forward. Both soil covering trays 4 are fixed to the bracket 31 by connecting rods 41.
[0045] The compaction mechanism 5 is installed on the rear side of the cover plate 4. It compacts the cover soil, increasing its density and thus improving its physical properties and water and fertilizer retention capacity. The compaction mechanism 5 includes a mounting rod 51, a wheel frame 52, a compaction wheel 53, a fixing plate 54, a second locking buckle 55, and an adjusting component 56. The mounting rod 51 is fixed to the rear of the frame 1. The wheel frame 52 is hinged to the mounting rod 51, and the compaction wheel 53 is rotatably mounted on the wheel frame 52, allowing the compaction wheel 53 to rotate around the mounting rod 51. The fixing plate 54 is fixedly mounted on the frame 1 via the second locking buckle 55, and an adjusting component 56 for adjusting the compaction pressure is installed between the fixing plate 54 and the wheel frame 52.
[0046] The adjusting assembly 56 includes a main rod 561, a secondary rod 562, a spring 563, an adjusting plate 564, and a fixing plate 565. The main rod 561 and the secondary rod 562 are slidably connected, and the end of the main rod 561 is hinged to the fixing plate 54. The end of the secondary rod 562 is hinged to the wheel frame 52. A fixing plate 565 is provided on the secondary rod 562. An adjusting plate 564 corresponding to the fixing plate 565 is threadedly connected to the main rod 561. A spring 563 is provided between the fixing plate 565 and the adjusting plate 564. The spring 563 is always in a compressed state, and the compression of the spring 563 can be adjusted by rotating the adjusting plate 564, thereby changing the elastic force and thus changing the pressure.
[0047] Specific work process:
[0048] The frame 1 is fixedly connected to the tail of the external power equipment. The external power equipment drives the frame 1 to move forward at a constant speed. During the forward movement, the furrow opening plate 25 can open planting furrows on the cultivated land; the motor 35 drives the sowing wheel 37 to rotate for sowing; the covering plate 4 covers the sown seeds; and finally, the compaction wheel 53 compacts the soil to ensure the normal growth of the seeds.
