Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a drive mechanism for intercropping. Background Technology

[0002] Corn-wheat intercropping is a unique planting pattern in some northern regions. Corn's growth cycle is generally 90-100 days. Corn is sown immediately after wheat harvest and continues until maturity, then wheat is sown again after corn harvest. This results in a short corn growing season, insufficient grain filling, and low yield. Some regions have researched and promoted intercropping techniques, where corn is sown 15-20 days before wheat harvest in reserved wheat rows, using 120-day-old corn varieties to extend the corn growing cycle and increase yield. An example of corn-wheat intercropping is as follows: the wheat planting strip is 90 cm wide, with 50 cm (or 60 cm) intervals, and two rows of corn are sown in the intervals. This allows for an average corn row spacing of 70 cm (or 75 cm), ensuring dense planting and a sufficient number of corn plants per acre. The improved ventilation and light penetration of the corn plants promote increased yield.

[0003] Currently, my country's agricultural machinery lacks dedicated seeders specifically designed for this intercropping technique. Traditional seeders, with their low profile and wide row spacing, are unsuitable for wheat ridge operations, negatively impacting wheat yield. While dedicated intercropping seeders have emerged, improving the structure and reducing row spacing, they lack the space for traditional drive mechanisms, necessitating electric drive. Furthermore, the row spacing cannot be adjusted to accommodate different planting patterns. Therefore, there is an urgent need to design a drive mechanism specifically for intercropping.

[0028] 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.

[0029] Reference Figure 1-10 A drive mechanism for intercropping includes a main beam 1, a clamping plate 2, a drive wheel 3, a transmission structure, a divider 4, and a drip irrigation tape furrow opener 5. The front end of the main beam 1 is connected to the frame beam 6 of the seeder via the clamping plate 2. The drive wheel 3 is installed at the rear end of the main beam 1. The main beam 1 is a hollow single-arm tube used to be set between two adjacent planting units 7 with small row spacing. The transmission structure is set inside the main beam 1, thereby avoiding increasing the width of the drive mechanism. The output end of the transmission structure is located on the side of the main beam 1 near the clamping plate 2, and the input end is connected to the drive wheel 3. The divider 4 is fixedly installed on the main beam 1 and located in front of the drive wheel 3. The drip irrigation tape furrow opener 5 is installed on the mounting base 12 at the rear end of the main beam 1.

[0030] In this embodiment, the transmission structure includes a drive shaft 9, a drive sprocket 10, a driven shaft, a driven sprocket, and a transmission chain 8. The drive shaft 9 passes through the rear end of the main beam 1 and is rotatably connected to the main beam 1. The drive sprocket 10 is fixed on the drive shaft 9 and located inside the main beam 1. A drive wheel 3 is fixedly mounted on the drive shaft 9. The driven shaft passes through the front end of the main beam 1 and is rotatably connected to the main beam 1. The driven sprocket is fixed on the driven shaft and located inside the main beam 1. Both ends of the driven shaft are respectively connected to the planting units on both sides. The transmission chain 8 is located inside the main beam 1, and the drive sprocket 10 and the driven sprocket are connected by the transmission chain 8. The rotation of the drive wheel 3 can drive the drive shaft 9 and the drive sprocket 10 to rotate, and then drive the driven sprocket and the driven shaft to rotate through the transmission chain 8. The driven shaft is connected to the planting unit 7, thereby providing power to the seed metering device of the planting unit.

[0031] In this embodiment, there are two drive wheels 3. The hubs 11 of the two drive wheels 3 are fixed at both ends of the drive shaft 9. The two drive wheels 3 correspond to a seed groove, so that in addition to providing drive, the drive wheels 3 can also play a role in pressing down the seed groove.

[0032] In this embodiment, the distance from the center of the hub 11 of the drive wheel 3 to the two end faces of the drive wheel 3 is different. By flipping the drive wheel 3 left and right, the distance between the two drive wheels 3 can be adjusted to adapt to different planting distances.

[0033] In this embodiment, the divider 4 includes a head 401 and two side wings 402. The head 401 is fixed to the main beam 1 by a connecting rod. The head 401 is triangular. The two side wings 402 are fixed on the two sides of the head 401 respectively, and the ends of the two side wings 402 away from the head 401 extend outward and backward, thereby pushing the wheat on both sides outward and preventing damage to the wheat during the corn planting process.

[0034] In this embodiment, a row of first connecting holes is provided on each of the two sides of the head 401, and a row of second connecting holes is provided on the side wing 402. The head 401 and the side wing 402 are fixedly connected by bolts. By aligning the first connecting holes and the second connecting holes at different positions, the bolts can be installed to adjust the distance between the ends of the two side wings 402, thereby adjusting the protection range of the divider 4.

[0035] In this embodiment, a diagonal brace is fixedly connected to the rear end of the main beam 1. The middle part of the mounting base 12 is rotatably connected to the end of the diagonal brace away from the main beam 1 via a rotating shaft. The drip irrigation tape furrow opener 5 is fixed to the rear end of the mounting base 12 by a U-shaped wire. The front end of the mounting base 12 is fixedly connected to the diagonal brace via a compression spring 13. By setting the compression spring 13, the furrow opening capacity of the furrow opener can be elastically adjusted.

[0036] In this embodiment, the drip irrigation tape furrow opener 5 includes a guide tube 501, a cutting blade 502, and a soil covering device 503. The guide tube 501 is fixedly connected to the mounting base 12 by a U-shaped wire. The cutting blade 502 is fixedly installed at the lower rear end of the guide tube 501. The soil covering device 503 is rotatably connected to the rear end of the cutting blade 502.

[0037] In this embodiment, the soil covering device 503 is a double-disc soil covering device, which includes two soil covering discs. The free ends of the pull arms of the two soil covering discs are rotatably connected to the cutter 502 through torsion springs 504. The torsion springs 504 enable the two soil covering discs to float elastically, thereby adapting to uneven ground.

[0038] In this embodiment, the conduit 501 is fixedly connected to the mounting base 12 by a U-shaped wire. By moving the fixed part of the conduit 501 and the U-shaped wire up and down, the depth of the trench can be adjusted to adapt to different drip irrigation tape laying requirements.
