Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a wheat and corn triangular seedling intercropping and dense planting planter. Background Technology

[0002] The existing wheat-corn intercropping method involves intercropping corn before wheat harvest, which allows for earlier sowing and extends the corn's growth cycle, offering significant advantages.

[0003] However, the existing intercropping model uses single-row intercropping of corn, and the intercropping model of wheat and corn is relatively arbitrary, especially in terms of controlling the intercropping spacing and row spacing, which cannot achieve the rational use of land and causes a certain amount of land waste.

[0004] The small double-row triangular seedling planting mode for corn involves planting corn in small double rows using two seed metering devices placed side by side, while the seeds discharged by the seed metering devices are staggered and fall on the ground. As a result, the seeds between the two rows form an isosceles triangle arrangement, while ensuring that the row spacing between the corn rows does not affect light and ventilation, thereby increasing planting density and improving yield. Utility Model Content

[0005] The technical problem to be solved by this utility model is the low land utilization rate of the existing intercropping model.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution: a wheat and corn triangular seedling intercropping dense planting planter, comprising a traction frame, a ground wheel, and seeding units. The seeding units perform small double-row triangular seedling intercropping. The planter is characterized by at least two seeding units arranged side-by-side on the traction frame via a four-bar linkage. The ground wheel is connected to the traction frame via a connecting frame. The ground wheel is linked to a transmission mechanism and a gearbox. The gearbox drives the seeding units to rotate synchronously via a drive mechanism to achieve seeding operation. The distance between the seeding units matches the corn intercropping area reserved during wheat planting, thereby enabling small double-row triangular seedling intercropping of corn within the reserved corn intercropping area.

[0007] Furthermore, at least two of the ground wheels are positioned in front of the seeding unit, the gearbox is mounted on the connecting frame, and the output shafts of the gearboxes are coaxially connected.

[0008] Furthermore, a weeder is provided in front of the seeding unit and is on the same axis as the seeding unit.

[0009] Furthermore, the weeder includes a weeding plate and a connecting plate. The bottom of the weeding plate is provided with a horizontally positioned wing that tilts from front to back, making the whole plate L-shaped. The two weeding plates are mounted side by side on the traction frame through the connecting plate, and the wings of the two weeding plates are opposite each other.

[0010] Furthermore, two dividing plates are provided on both sides of the seeding unit, and the ends of the dividing plates at the weeder are inclined inward and connected or inclined inward and not connected. The dividing plates at the seeding unit extend backward to the soil covering and pressing wheel, and the two dividing plates surround the seeding unit and the weeder.

[0011] Furthermore, the seeding unit includes a unit frame and seed metering device, seed furrow opener, disc furrow opener, chain box seed guide, and soil covering and pressing wheel set on the unit frame. Two seed metering devices are connected side by side and coaxially and linked with the drive mechanism. The seeds discharged are staggered and fall into the disc furrow opener through the chain box seed guide. The unit frame is provided with connecting holes to adjust the distance between the two seed metering devices. The seed furrow opener, disc furrow opener, soil covering device, and soil covering and pressing wheel are coaxially corresponding.

[0012] Furthermore, the distance between the two seeders is 20-30cm.

[0013] Furthermore, the single-unit frame is equipped with a drip irrigation tape placement rack and a drip irrigation guide frame. The drip irrigation guide frame is located between the disc furrow opener and the soil covering and pressing wheel, so that the corn drip irrigation tape is laid in the middle of the small double rows of corn.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This application improves upon existing seeders by using a small double-row triangular seedling planting pattern in the reserved corn intercropping area during wheat sowing. This optimizes the intercropping pattern of wheat and corn, increases the corn planting density, improves land utilization in intercropping, and increases yield.

[0016] 2. This application adopts an eight-row sowing pattern for wheat, improves the row spacing and sowing pattern of wheat, further optimizes the intercropping pattern of wheat and corn, and further improves land utilization.

[0017] 3. In this application, the gearbox and the ground wheel are connected as a whole by a connecting frame and are located in front of the seeding unit and on the same axis as the seeding unit, reducing the impact on wheat. The power of the ground wheel is directly transmitted to the input shaft of the gearbox through the transmission mechanism, and then the output shaft of the gearbox drives the seed metering device through the drive mechanism. One gearbox can complete the speed adjustment, which is convenient to operate, reduces costs, and the integrated design also saves the internal space of the seeder and reduces interference with other equipment during maintenance. The input shafts and output shafts of the two gearboxes are connected by a through shaft, so that even when the ground is uneven and one ground wheel is not in contact with the ground and is rotating, the seed metering device can still be driven by the other ground wheel.

[0018] 4. In this application, the weeder is positioned in front of the seeding unit and on the same axis as the seeding unit. During the sowing process, the weeder can cut and / or remove the weeds in front of the seeding unit from the soil, making it easier for the seeding unit to sow.

[0019] 5. In this application, the sowing furrow opener and the disc furrow opener are arranged in a front-to-back manner. The sowing furrow opener first opens the furrow in the sowing area and removes debris from the sowing area, which facilitates the disc furrow opener to sow seeds in the furrow area opened by the sowing furrow opener while preventing debris from affecting the disc furrow opener. The height of the seed metering device is increased by the chain box seed guide, so that the seed metering device is above the wheat, which improves the passability. Moreover, the chain box seed guide replaces the seed metering tube, which improves the stability of seed metering and solves the problem that when the height of the seed metering device is increased, the seeds collide and fall in the seed metering tube, causing the sowing position to be unstable and affecting the quality of triangular seedling sowing.

[0020] 6. In this application, two dividing plates are respectively set on both sides of the seed unit, and the ends of the dividing plates at the weeder are inclined inward and connected or inclined inward and not connected. The dividing plates at the seed unit extend backward to the covering and pressing wheel. The two dividing plates surround the seed unit and the weeder. The ends of the dividing plates are inclined inward and form an arrow shape, which can separate and guide the wheat that has invaded the weeder and the seed unit, so that the wheat leaves the intercropping area and reduces the impact on sowing.

[0021] 7. In this application, a drip irrigation tape placement rack is provided on the single frame. The drip irrigation tape is laid on the ground through the drip irrigation tape guide rack and is located between two rows of corn, realizing the integrated operation of sowing and drip irrigation tape laying, which facilitates watering and fertilization through the drip irrigation tape and ensures the growth of corn.

[0036] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0039] like Figure 1-2 As shown, a wheat and corn triangular intercropping dense planting planter includes a traction frame 1, a ground wheel 2, and seeding units 3. The seeding units 3 perform small double-row triangular seeding in a planting pattern. At least two seeding units 3 are arranged side-by-side on the traction frame 1 via a four-link linkage 4. The ground wheel 2 is connected to the traction frame 1 via a connecting frame 5. The ground wheel 2 is linked to a transmission mechanism 6 via a transmission mechanism 9. The transmission mechanism 6 drives the seeding units 3 to rotate synchronously via a drive mechanism 10 to achieve seeding. The distance between the seeding units 3 matches the corn intercropping area reserved during wheat planting. The small double-row triangular seeding increases the corn planting density in the intercropping area without changing the plant spacing, affecting light and ventilation, and increasing yield. The distance between the seeding units 3 is adjusted by moving them on the traction frame 1 to match the distance between them with the corn intercropping area reserved during wheat planting.

[0040] Of course, by adjusting the distance between the seeding units, and based on the reserved intercropping area width and corn planting requirements, two seeding units can be placed in the same intercropping area. In the same intercropping area, two seeding units can simultaneously carry out large double-row sowing, and each large double-row can be sown with small double-rows staggered. At the same time, the corn seeds in the two adjacent small rows in the two large double-rows are also staggered on the ground, so as to achieve the rational use of space in the intercropping area.

[0041] The single frame 35 is equipped with a drip irrigation tape placement rack 7 and a drip irrigation guide rack 8. The drip irrigation tape is laid on the ground through the drip irrigation tape guide rack and is positioned between two rows of corn, realizing the integrated operation of sowing and drip irrigation tape laying, which facilitates watering and fertilization through the drip irrigation tape and ensures the growth of corn. Example 2

[0042] like Figure 1 and 2 As shown, this embodiment is obtained by connecting the ground wheel 2 and the connecting frame 5 based on the technical features of embodiment one. The remaining technical features are the same as those of embodiment one, and the similarities will not be repeated here. The difference between this embodiment and embodiment one is that: at least two ground wheels 2 are set in front of the seeding unit 3, the gearbox 6 is set on the connecting frame 5, the unit frame 35 is provided with a connecting hole 37 for adjusting the distance between the two seed metering devices 31, and the output shafts of the gearboxes 6 are coaxially connected; the transmission mechanism 9 and the drive mechanism 10 are chains or drive shafts.

[0043] In this embodiment, the gearbox 6 and the ground wheel 2 are connected as a whole by the connecting frame 5 and are set in front of the sowing unit 3 and on the same axis as the sowing unit 3, reducing the impact on wheat. The power of the ground wheel 2 is directly transmitted to the input shaft of the gearbox 6 through the transmission mechanism 9, and then the output shaft of the gearbox 6 drives the seed metering device 31 through the drive mechanism 10. One gearbox 6 can complete the speed adjustment, which is convenient to operate, reduces costs, and the integrated design also saves the internal space of the seeder and reduces interference with other equipment during maintenance. The input shafts and output shafts of the two gearboxes 6 are connected by a shaft. When the ground is uneven and one ground wheel 2 is not in contact with the ground, it can still drive the seed metering device 31 under the drive of the other ground wheel 2. The distance between the two seed metering devices 31 can be adjusted by installing the seed metering device 31 with different connecting holes 37 on the unit frame 35, thereby adjusting the small row spacing to match the size of the corn intercropping area reserved when planting wheat. Example 3

[0044] like Figure 3As shown, this embodiment is obtained by adding technical features such as weeder 11 on the basis of embodiment one. The other technical features are the same as those in embodiment one. The similarities will not be repeated here. The difference between this embodiment and embodiment one is that a weeder 11 is provided in front of the seeding unit 3 and is on the same axis as the seeding unit 3.

[0045] In this embodiment, the weeder 11 includes a weeding plate 111 and a connecting plate 112. The bottom of the weeding plate 111 is provided with a horizontally positioned and backward-sloping wing 113, making it L-shaped. The two weeding plates 111 are arranged side by side on the traction frame 1 through the connecting plate 112, and the wings 113 of the two weeding plates 111 are opposite to each other. The weeder 11 is positioned in front of the seeding unit 3 and is on the same axis as the seeding unit 3. During the sowing process, the weeding plate 111 drives the wing 113 to extend into the soil. The horizontally positioned wing 113 can scoop out the weeds in front of the seeding unit 3 from the soil, making it easier for the seeding unit 3 to sow.

[0046] The traction frame 1 is equipped with a weeding fixing block 114. The connecting plate 112 extends into the through hole provided on the weeding fixing block 114. Then, the fixing bolt passes through the weeding fixing block 114, extends into the through hole, and presses against the connecting plate 112, fixing the connecting plate 112 in the weeding fixing block 114. The fixing structure formed by the weeding fixing block 114 and the fixing bolt can adjust the soil penetration depth of the weeding plate 111 and the flying wing 113, and facilitate replacement. Example 4

[0047] like Figure 3 As shown, this embodiment is obtained by describing the technical features of the sowing unit 3 in detail based on the first embodiment. The remaining technical features are the same as those in the first embodiment, and the similarities will not be repeated here. The difference between this embodiment and the first embodiment is that the sowing unit 3 includes a unit frame 35 and a seed metering device 31, a seed furrow opener 32, a disc furrow opener 34, a chain box seed guide 36, and a soil covering and pressing wheel 33 set on the unit frame 35. The two seed metering devices 31 are connected side by side and coaxially and are linked with the drive mechanism 10. The seeds discharged are staggered and fall into the disc furrow opener 34 through the chain box seed guide 36. The seed furrow opener 32, the disc furrow opener 34, the soil covering device, and the soil covering and pressing wheel 33 are coaxially corresponding. A dividing plate 38 is set in front of the two seed furrow openers 32. The drip irrigation guide frame 8 is located between the disc furrow opener 34 and the soil covering and pressing wheel 33.

[0048] In this embodiment, the sowing furrow opener 32 and the disc furrow opener 34 are positioned in a front-to-back manner. The sowing furrow opener 32 first opens furrows in the sowing area and removes debris from the sowing area, which facilitates the disc furrow opener 34 to sow seeds in the furrowed area of ​​the sowing furrow opener 32 while preventing debris from affecting the disc furrow opener 34. The height of the seed metering device 31 is increased by the chain box seed guide 36, so that the seed metering device 31 is above the wheat, improving the passability. Moreover, the chain box seed guide 36 replaces the seed metering tube, improving the stability of seed metering and solving the problem that when the height of the seed metering device 31 is increased, the seeds collide and fall in the seed metering tube, causing the sowing position to be unstable and affecting the quality of triangular seedling sowing.

[0049] Two dividing plates are provided on both sides of the seeding unit, and the ends of the dividing plates at the weeder are inclined inward and connected or inclined inward and not connected. The dividing plates at the seeding unit extend backward to the soil covering and pressing wheel, and the two dividing plates surround the seeding unit and the weeder.

[0050] Two dividing plates 38 are respectively set on both sides of the sowing unit 3, specifically fixed on both sides of the unit frame 35. The two dividing plates 38 surround the sowing unit 3 and the weeder 11, and the ends of the dividing plates 38 at the weeder 11 are inclined inward, so that the two dividing plates 38 form an arrow shape as a whole. The dividing plates 38 at the sowing unit 3 extend backward to the soil covering and pressing wheel 37, which can separate and guide the wheat that has invaded the weeder 11 and the sowing unit 3, so that the wheat leaves the intercropping area and reduces the impact of wheat on sowing.

[0051] The two dividing plates 38 are not connected at their inwardly inclined ends, which allows the dividing plates 38 to move and adjust together with the two seeding units 3 when the distance between them is adjusted through the connecting hole 37, so that the width of the dividing plates 38 matches the width of the small double-row sowing.

[0052] The two dividing plates 38 are connected together at their inwardly inclined ends to facilitate forming and processing, such as using a steel plate or an elastic plastic plate formed by stamping and bending. When adjusting the distance between the two seeding units 3, the elastic deformation of the steel plate or plastic plate can be used to move and adjust the width of the dividing plate 38 accordingly.

[0053] The dividing plate 38 can guide and distribute invading wheat, causing it to leave the intercropping area and reducing wheat loss.

[0054] The seeder 32 includes a furrowing block 321, an arc-shaped plate 322, and an elastic arc-shaped connecting plate 323. The furrowing block 321 is fixed to the single frame 35. One end of the arc-shaped connecting plate 323 extends into the through hole of the furrowing block 321 and is fixed to the furrowing block 321 by fixing bolts, which facilitates disassembly and replacement. The other end of the arc-shaped connecting plate 323 faces the weeder 11 from top to bottom. The arc-shaped plate 322 is located at the other end of the arc-shaped connecting plate 323. When sowing, the arc-shaped plate 322 extends into the soil. Because the arc-shaped connecting plate 323 is elastic, it can undergo elastic deformation when encountering hard objects such as stones and use its elasticity to push small hard objects to move, thus playing a buffering role.

[0055] The overall technical solution formed by the above embodiments is used in another technical solution disclosed in this application, which is as follows: Figure 4-5 As shown, a method for dense intercropping wheat and corn using a triangular seedling spacing method involves sowing corn within a pre-reserved area during wheat planting. The corn is sown using a small double-row triangular seedling spacing pattern, with drip irrigation tape laid between the small double rows. When using the aforementioned seeder, the positions of the seeding unit 3 and the ground wheel 2 are aligned with the corn intercropping area. The power of the ground wheel 2 is directly transmitted to the input shaft of the gearbox 6 via the transmission mechanism 9. The output shaft of the gearbox 6 then drives the seed metering device 31 via the drive mechanism 10 to perform the seed metering operation. The seeds discharged by the seed metering device 31 are guided by a chain-box seed guide 36, and then fall staggeredly into the soil between the disc furrow openers 34. On the ground, small double-row triangular seedlings are sown. The drip irrigation tape is laid on the ground through the drip irrigation tape guide frame, with the drip irrigation tape positioned between the two rows of corn. The drip irrigation guide frame 8 is set between two disc furrow openers 34. The soil pushed out by the disc furrow openers 34 when they furrow open and separate the soil covers the drip irrigation tape, realizing the integrated operation of sowing and drip irrigation tape laying. During the sowing process, the weeding board 111 drives the flying wing 113 to extend into the soil layer. The flying wing 113, which is in a horizontal position, can shovel the weeds in front of the sowing unit 3 from the soil. When the grass roots are deep, the flying wing 113 can cut the grass in the middle of the grass roots and shovel the upper part of the grass out of the soil. The flying wing 113 is tilted from front to back, which facilitates the movement of the flying wing in the soil layer and reduces the movement resistance.

[0056] The width of the corn intercropping area is 52cm, and the row spacing of the small double rows of corn is 20-30cm, preferably 28cm. By adjusting the position between the sowing units 3, different corn intercropping area widths can be accommodated, and the distance between the seed metering devices 31 can be adjusted to accommodate different small row spacings for sowing, so that the intercropping corn planting mode can be adjusted according to the corn intercropping area reserved when planting wheat.

[0057] The wheat planting width is 52cm; the wheat is planted in an eight-row planting pattern with row spacing of 7cm, 8.5cm, 7cm, 7cm, 7cm, 8.5cm, and 7cm, and wheat drip irrigation tape is laid within the 8.5cm row spacing; this is to optimize and improve the wheat planting method, further promote the rational use of the land as a whole, reduce the unreasonable use of land caused by unreasonable wheat planting, thereby increasing the area of ​​corn intercropping and increasing the overall yield.

[0058] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
