Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more particularly to a corn 2:2 empty fallow rotation seeder. Background Technology

[0002] In the field of mechanized corn planting, integrated sowing and fertilizing machines are increasingly widely used. Existing corn planters typically employ a "one row, one fertilizer" structure, meaning each planting row corresponds to a set of furrowing and seed-dispensing mechanisms and a set of furrowing and fertilizer-dispensing mechanisms to complete seed sowing and fertilizer application respectively. Simultaneously, their transmission systems often employ multi-stage chain or gear drives, relying on the tractor's rear power take-off (PTO) shaft or an independent motor to drive the seed and fertilizer dispensers. However, the above technical solutions still have the following technical problems in practical applications: (1) Traditional seeders are equipped with an independent fertilizer dispensing mechanism for each row of seeds, forming a "one row, one seed, one fertilizer" correspondence. Although this structure achieves synchronization of sowing and fertilization in form, the fertilizer is concentrated next to the seeds in each row, resulting in overlapping distribution areas. This makes it difficult for the corn roots to fully absorb the fertilizer during the seedling stage, and a large amount of nutrients are fixed or lost in the soil. In order to meet the nutrient requirements of corn throughout its entire growth period, it is necessary to increase the amount of fertilizer applied per acre, which leads to serious fertilizer waste, high production costs, and increases the risk of soil compaction and non-point source pollution.

[0003] (2) The seed metering device and fertilizer metering device of the existing seeders are mostly driven by the ground wheel and the tractor rear output shaft (PTO) or hydraulic motor. The transmission path is long and there are many links, which not only increases the structural complexity and manufacturing cost of the machine, but also makes it difficult to accurately guarantee the consistency of seed metering and fertilizer metering. This can easily lead to problems such as asynchronous seeding and fertilization, delayed or advanced seeding, which affects the seeding quality.

[0004] Therefore, it is necessary to design a corn 2:2 empty fallow rotation seeder to solve the problems existing in the above-mentioned technologies. Summary of the Invention

The soil covering devices are connected to the first frame through a first connecting structure. The compaction component includes compaction wheels disposed behind the soil covering devices and corresponding to each other. The compaction wheels are connected to the first frame through a second connecting structure.

[0011] According to the corn 2:2 empty fallow rotation seeder provided by the present invention, the second connecting structure includes a connecting frame connected to the press wheel, the end of the connecting frame is hinged to the first frame, and the middle part is connected to the first frame through a second elastic part.

[0012] According to the corn 2:2 empty fallow rotation hill planter provided by the present invention, a second hill planter is respectively provided on both sides of the first hill planter unit.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example This invention provides a 2:2 empty fallow rotation hill planter for corn. Please refer to [link / reference]. Figures 1-13 The system includes a first hill-sowing unit 1, which includes a first frame 11. Ground wheels 12 are respectively provided on both sides of the front end of the first frame 11, and a first ditching and fertilizing mechanism 13 is provided in the middle. First ditching and seeding mechanisms 14 are respectively provided on both sides of the rear of the first ditching and fertilizing mechanism 13. The first ditching and seeding mechanisms 14 are connected to the first frame 11, and a first soil covering and compaction mechanism 15 is provided behind it. The first soil covering and compaction mechanism 15 is connected to the first frame 11 and corresponds to the ditching ends of the first ditching and fertilizing mechanism 13 and the first ditching and seeding mechanism 14. The ground wheels 12 are connected to a first drive shaft 17 via a first transmission assembly 16. The first drive shaft 17 is rotatably connected to the first frame 11, and the first drive shaft 17 is connected to the fertilizing end of the first ditching and fertilizing mechanism 13 and the seeding end of the first ditching and seeding mechanism 14 via a second transmission assembly 18 and a third transmission assembly 19, respectively.

[0022] In this embodiment, the ground wheel 12 is rotatably connected to the wheel frame 121. The vertical section of the wheel frame 121 is slidably inserted into the mounting sleeve 122. The mounting sleeve 122 is threaded with a fixing bolt. The screw end of the fixing bolt is inserted into a fixing hole on the vertical section of the wheel frame 121. There can be several fixing holes, which are arranged at intervals along the vertical direction, so that the height of the ground wheel 12 can be adjusted.

[0023] The transmission assembly 16 includes a mounting shell 161 fixed on the wheel frame 121. The axle of the ground wheel 12 passes through the mounting shell 161 and is connected to the shaft 162 by two meshing bevel gears. A shaft plate 163 is detachably connected to the first frame 11 by bolts. A mounting shell 164 is fixed to the end of the shaft plate 163. A bushing 165 is fixed to the side of the mounting shell 164. The end of the shaft 162 extends into the mounting shell 164 through the bushing 165 and is connected to the first transmission shaft 17 by two meshing bevel gears.

[0024] When the ground wheel 12 rotates, it drives the wheel axle to rotate. The wheel axle drives the shaft 162 to rotate through two meshing bevel gears. The shaft 162 drives the first transmission shaft 17 to rotate through two meshing bevel gears.

[0025] The first ditching and fertilizing mechanism 13 is located at the front center of the first frame 11 and is used to ditch and fertilize the ridges; the two first ditching and seeding mechanisms 14 are symmetrically arranged on both sides behind the first ditching and fertilizing mechanism 13 and are used to ditch and sow the ridges; the first soil covering and compacting mechanism 15 is used to cover and compact the fertilized and sown furrows.

[0026] The first frame 11 has an upper suspension arm 111 fixed at the front center and lower suspension arms 112 fixed on both sides. The upper suspension arm 111 and the lower suspension arm 112 enable the first seeding unit 1 to be used in conjunction with a small agricultural vehicle.

[0027] During operation, the ground wheel 12 rolls forward, and the ditching ends of the first ditching and fertilizer dispensing mechanism 13 and the first ditching and seed dispensing mechanism 14 open ditches. At the same time, the ground wheel 12 drives the first transmission shaft 17 to rotate through the transmission component 16. The first transmission shaft 17 drives the fertilizer dispensing end of the first ditching and fertilizer dispensing mechanism 13 and the seed dispensing end of the first ditching and seed dispensing mechanism 14 to dispense fertilizer and seeds into the opened ditches through the transmission component 2 18 and the transmission component 3 19, respectively. Then, the first soil covering and compacting mechanism 15 covers the fertilized and sown ditches with soil and compacts them to complete the sowing and fertilization operation of one row.

[0028] By adopting this scheme, through the coordinated operation of the first ditching and fertilization mechanism 13 and the two first ditching and seeding mechanisms 14, two rows of seeds can be sown simultaneously on the same ridge, and full-layer fertilization can be carried out between the two rows of seeds, which effectively reduces the amount of fertilizer and saves planting costs.

[0029] The scheme is further optimized. The first ditching and fertilizer discharge mechanism 13 includes a fertilizer discharge disc ditcher 131 set in the middle of the front end of the first frame 11. The fertilizer discharge disc ditcher 131 is connected to the fertilizer discharger 133 through the fertilizer discharge pipe 132. The fertilizer discharger 133 is fixedly installed at the bottom of the fertilizer box 134. The fertilizer box 134 is fixedly connected to the first frame 11 through the fertilizer box 134 frame. The fertilizer discharger 133 is connected to the first transmission shaft 17 through the transmission assembly 2 18.

[0030] In this embodiment, the vertical rod 1311 of the fertilizer discharge disc furrow opener 131 is slidably inserted into the adjusting sleeve 1312. Multiple limiting holes are provided on the vertical rod 1311 at intervals along the vertical direction. A limiting bolt is threaded onto the adjusting sleeve 1312, and the screw end of the limiting bolt is inserted into one of the limiting holes. This allows the height of the fertilizer discharge disc furrow opener 131 to be adjusted.

[0031] The transmission component 2 18 can be configured as a chain and sprocket drive or a synchronous belt and synchronous pulley drive. When the ground wheel 12 drives the first transmission shaft 17 to rotate through the transmission component 1 16, the transmission component 2 18 drives the fertilizer discharger 133 to move, so that the fertilizer in the fertilizer box 134 falls into the ditch opened by the fertilizer discharge disc ditch opener 131 through the fertilizer discharger 133 and the fertilizer discharge pipe 132 in sequence.

[0032] In a further optimized scheme, the first furrowing and seeding mechanism 14 includes a seed metering device 141 fixedly connected to the first frame 11. A seed box 142 is provided on the top of the seed metering device 141, and a seed metering obtuse angle furrow opener 143 is provided on the bottom. The seed metering obtuse angle furrow opener 143 is connected to the first frame 11, and the seed metering device 141 is connected to the first drive shaft 17 through the transmission assembly 3 19.

[0033] In this embodiment, the seed metering device 141 is configured as a finger-clamp seed metering device, sowing two seeds per hole. The transmission component three 19 has the same structure as the transmission component one 16, except that the shaft of the transmission component three 19 is connected to the input shaft of the gearbox 191 through two meshing bevel gears. The gearbox 191 is fixedly connected to the first frame 11 and has two output shafts, which are respectively connected to the two seed metering devices 141. This allows the two seed metering devices 141 to work synchronously. The discharged seeds fall into the opened furrow through the middle of the seed metering obtuse angle furrow opener 143. The front end top surface of the seed metering obtuse angle furrow opener 143 is fixed with a mounting bracket 1431, which is fixed to the first frame 11 by bolt connection. The seed metering obtuse angle furrow opener 143 can be installed and fixed. At the same time, multiple rows of connecting holes are provided on the first frame 11 as needed, so that the height of the seed metering obtuse angle furrow opener 143 can be adjusted.

[0034] The scheme is further optimized. The first soil covering and compaction mechanism 15 includes a soil covering component 151 and a compaction component 152 located behind the first ditching and seeding mechanism 14. The soil covering component 151 includes a soil covering device 1511 corresponding to the ditching end of the first ditching and fertilizer dispensing mechanism 13 and the first ditching and seeding mechanism 14, respectively. The soil covering device 1511 is connected to the first frame 11 through a first connecting structure. The compaction component 152 includes a compaction wheel 1521 located behind the soil covering device 1511 and corresponding to each other. The compaction wheel 1521 is connected to the first frame 11 through a second connecting structure.

[0035] In this embodiment, the first connecting structure includes a crossbeam 1512 fixedly connected to the support of the soil covering device 1511. The two sides of the crossbeam 1512 are respectively hinged to the first frame 11 through connecting rods 1513, and the top is connected to the first frame 11 through a first elastic part. The first elastic part includes a first pin 1514 that passes through the first frame 11 and the crossbeam 1512. A first spring 1515 is sleeved on the first pin 1514, and the two ends of the first spring 1515 abut against the first frame 11 and the crossbeam 1512, respectively. The soil covering effect can be improved by setting the first elastic part.

[0036] The second connection structure includes a connecting frame 1522 that is rotatably connected to the press wheel 1521. The end of the connecting frame 1522 is hinged to the first frame 11, and the middle part is connected to the first frame 11 through the second elastic part. The second elastic part includes a second pin 1523 that passes through the first frame 11 and the connecting frame 1522. A second spring 1524 is sleeved on the second pin 1523, and the two ends of the second spring 1524 abut against the first frame 11 and the connecting frame 1522, respectively. The installation of the second elastic part can improve the pressing effect.

[0037] Further optimize the plan, such as Figure 10 As shown, a second seeding unit 2 is provided on both sides of the first seeding unit 1. The second seeding unit 2 includes a second frame 21, which is connected to the first frame 11 through a width adjustment component 22. A second ditching and fertilization mechanism is provided at the front center of the second frame 21. A second ditching and seeding mechanism is provided on both sides of the rear of the second ditching and fertilization mechanism. The second ditching and seeding mechanism is connected to the second frame 21, and a second soil covering and compaction mechanism is provided behind it. The second soil covering and compaction mechanism is connected to the second frame 21 and corresponds to the ditching end of the second ditching and fertilization mechanism and the second ditching and seeding mechanism. A second drive shaft is rotatably connected to the second frame 21. The second drive shaft is connected to the first drive shaft 17 via a coupling. The second drive shaft is also connected to the fertilizer discharge end of the second ditching and fertilizer discharge mechanism and the seed discharge end of the second ditching and seed discharge mechanism via transmission assembly four and transmission assembly five, respectively.

[0038] In this embodiment, the second ditching and fertilizing mechanism, the second ditching and seeding mechanism, and the second soil covering and compaction mechanism all adopt the same structure as the first ditching and fertilizing mechanism 13, the first ditching and seeding mechanism 14, and the first soil covering and compaction mechanism 15. Since the second seeding unit 2 does not have a ground wheel 12, each second seeding unit 2 is equipped with a separate second drive shaft. The two ends of the first drive shaft 17 pass through the mounting shell 2 164 and are connected to the second drive shaft through a coupling, thus enabling the second drive shaft to rotate. The fourth and fifth transmission components adopt the same structure as the second transmission component 18 and the third transmission component 19, respectively. Thus, when the second drive shaft rotates, it can respectively drive the fertilizing end of the second ditching and fertilizing mechanism and the seeding end of the second ditching and seeding mechanism to work.

[0039] Further optimize the plan, such as Figure 12 As shown, the first hole-planting unit 1 is connected to the second hole-planting unit 2 on both sides by a width adjustment component 22. The second hole-planting unit 2 has the same structure as the first hole-planting unit 1.

[0040] It should be noted that the combination of the first seeding unit 1 and the two second seeding units 2 can be used with large and medium-sized agricultural vehicles.

[0041] The design was further optimized so that the width adjustment component 22 can be adjusted from 100cm to 130cm, which is suitable for standard row spacing of 65cm or 80cm.

[0042] like Figure 11As shown, the width adjustment component 22 includes an adjustment rod 221. Both ends of the adjustment rod 221 are inserted into square tubes on the first frame 11 and the second frame 21, respectively, and then the two are connected and fixed by a pin or bolt. Simultaneously, by providing multiple adjustment holes 222 at intervals on both sides of the square tube of the first frame 11, the spacing between the first sowing unit 1 and the second sowing unit 2 can be adjusted, thus making the invention applicable to standard ridge planting of corn at 65cm and 80cm.

[0043] Among them, such as Figure 12 As shown, the wide-row, well-ventilated, two-to-two-space (fallow rotation) cultivation pattern for corn is as follows: Sowing design: Sow two rows per ridge (row spacing 30cm), and leave one ridge unsown (empty ridge). Post-sowing corn row formation: Narrow row spacing 30cm, wide row spacing: 65cm ridge, wide row 100cm or 80cm ridge, wide row 130cm (this cultivation method provides good ventilation and can achieve the superior ventilation performance of corn edge rows).

[0044] Sowing requirements: Sow two plants per hole (simultaneous sowing in two narrow rows), plant spacing: 33-50cm (adjustable).

[0045] Planting density per mu: 5000 plants per mu for densely planted corn, 4000 plants per mu for sparsely planted large-eared corn.

[0046] The cultivation design of this invention can increase corn planting density by 10%-20%, increase corn yield per mu by 10%-20%, and achieve a corn yield of over 2000 jin per mu.

[0047] Fertilization: Fertilization is carried out by creating a furrow between two narrow rows of corn and applying fertilizer to the entire soil layer. The recommended fertilizer application rate is 84 grams per linear meter. For corn with a 65cm ridge, the fertilizer application rate per mu (66 catties / acre) is (84 grams × 513 linear meters). For corn with an 80cm ridge, the fertilizer application rate per mu is (84 grams × 416 linear meters) = 70 catties. For conventional corn planting, the fertilizer application rate per mu is (60 grams × 1026 linear meters) = 123 catties. Comparison: 65cm ridge corn saves 30% of fertilizer per mu. 80cm ridge corn saves 43% of fertilizer per mu. Corn sowing and fertilization are completed randomly in one step. Corn field management does not require topdressing, chemical growth regulators, or yield-enhancing agents.

[0048] like Figure 13 As shown, the high-light-efficiency, well-ventilated, two-to-two-empty (fallow rotation) cultivation model for maize is as follows: 65cm standard ridges, two rows are sown per ridge (row spacing 30cm), and one ridge is left unsown (empty ridge).

[0049] Sowing design: two plants per hole (wide and narrow holes); two rows (wide and narrow holes) sown simultaneously.

[0050] Plant spacing: Wide plant spacing: 60cm-66cm; Narrow plant spacing: 30cm-33cm.

[0051] Planting density per mu: 4000-4500 plants.

[0052] This cultivation design allows for cross-ventilation and light penetration in both the horizontal and vertical directions of the corn plant, achieving high light efficiency and comprehensive light penetration. It also increases corn planting density by 10%-20% and improves yield per mu (unit of land area) by 10%-20%. Furthermore, this cultivation technique promotes large ears on each corn plant, making it suitable for large-ear corn and green waxy corn cultivation, achieving a yield of over 2000 jin (unit of weight) per mu.

[0053] This cultivation method is suitable for planting corn on 130cm wide ridges, making full use of the potential for fallowing the furrows of the 130cm wide corn ridges. The following year, when planting corn, the ridges can be converted into furrows, and the furrows into ridges.

[0054] Fertilization: Fertilizer is applied in a furrow between two narrow rows of corn, covering the entire corn layer. 84 grams of fertilizer are applied per linear meter, yielding 86 jin per mu (approximately 48 catties per acre). Fertilization is done randomly at the time of sowing and completed in one session. No further topdressing, chemical growth regulators, or yield-enhancing agents are needed for field management. Comparison: Fertilizer savings of 30% are possible.

[0055] This invention has the following technological innovations: (1) This invention designs a wide-row permeable technology for corn with two plants per hole, two narrow rows per hole simultaneously, two rows planted and two empty rows (empty ridges), and two rows of corn with two plants per hole with wide and narrow holes simultaneously, realizing a technological innovation of high light efficiency and vertical and horizontal permeability of corn, which can increase the planting density of corn per mu by 10%-20% and increase the yield of corn per mu by 10%-20%.

[0056] (2) The present invention designs a 2:2 empty fallow rotation cultivation technology for corn. Since 50% of the empty rows of corn are not fertilized, and the two rows of corn are reformed to apply fertilizer once, the two technologies can reduce fertilizer (conventional corn planting requires 60 grams of fertilizer per linear meter, and 123 jin of fertilizer per mu): Corn planted in 65cm ridges with two rows and two gaps: 86 catties of fertilizer per mu (unit of land area), compared to: 30% less fertilizer per mu.

[0057] Corn planted in 80cm ridges with two rows per 2 rows: 70 catties of fertilizer per mu (unit of land area), compared to: fertilizer reduction of 43% per mu.

[0058] (3) Corn rotation with a 2:2 ratio of empty ridges and fallow land, achieving 50% empty ridges for corn, with one year of fallow land in the current year. Through one year of fallow land, the soil can be restored to its granular structure and fertility. After one year of fallow land, the fallow ridges planted in the second year are soft stubble, which can retain water, moisture and fertilizer, thereby protecting the sustainable use of corn farmland for planting.
