Technical Field

[0001] This utility model belongs to the technical field of agricultural harvesting devices, and in particular a grain divider for a grain combine harvester. Background Technology

[0002] A divider is a device installed at the front end of a crop harvesting machine to lift upright or lodged crop stalks. The tip of the divider must be close to the ground and float relative to the ground to adapt to ground undulations and lift the stalks from the base, reducing the loss of ears.

[0003] When harvesters operate in fields with a lot of weeds, weeds sometimes accumulate on the divider, and the accumulation becomes more and more severe, which seriously affects the dividing of grain and pushes the crops in front, making it impossible to operate. Therefore, there is an urgent need for a divider for grain combine harvesters. Utility Model Content

[0016] Combination Figures 1-4 Description: A grain divider for a grain combine harvester includes: a divider assembly 1, a weed-blocking unit 2, and a support unit 3. Two weed-blocking units 2 are symmetrically rotatably connected to the divider assembly 1. The divider assembly 1 is fixedly connected to the support unit 3, and the support unit 3 is rotatably connected to the two weed-blocking units 2 respectively.

[0017] The divider assembly 1 includes: a divider base plate 1-1, a divider cover 1-2, a cavity 1-3, a battery 1-4, a controller 1-5, and a solar panel 1-6. The divider cover 1-2 is fixed to the upper end of the divider base plate 1-1. Openings are provided on both sides of the divider cover 1-2. The cavity 1-3 is located at the upper end of the divider cover 1-2. The battery 1-4 and the controller 1-5 (which includes a charging controller, a PLC controller, and an inverter) are fixed inside the cavity 1-3. The solar panel 1-6 is fixed to the upper end of the divider cover 1-2. The solar panel 1-6 is connected to the controller 1-5 and the battery 1-4 via wires. The battery 1-4 is also connected to the controller 1-5 via wires. The PLC controller is used to control the rotation of the drive motor 2-2 and the synchronous extension and retraction of the electric telescopic rod 3-2.

[0018] Both of the aforementioned grass-blocking units 2 include: a grass-blocking plate 2-1, a drive motor 2-2, and a cutting wheel 2-3. The grass-blocking plate 2-1 is rotatably connected to the two opposite inner sides of the divider cover 1-2. The grass-blocking plate 2-1 is located at the opening of the divider cover 1-2. The drive motor 2-2 is fixed to the side of the grass-blocking plate 2-1. The cutting wheel 2-3 is fixed on the output shaft of the drive motor 2-2. The cutting wheel 2-3 has an arc-shaped cutter on its circumferential side. The drive motor 2-2 is connected to the battery 1-4 through a wire.

[0019] The support unit 3 includes a support plate 3-1 and an electric telescopic rod 3-2. The support plate 3-1 is fixed on the bottom plate 1-1 of the divider. The fixed end of the electric telescopic rod 3-2 is rotatably connected to the support plate 3-1, and the movable end of the electric telescopic rod 3-2 is rotatably connected to the grass barrier 2-1. Two electric telescopic rods 3-2 are symmetrically arranged with the support plate 3-1 as the center. The two electric telescopic rods 3-2 are respectively connected to the battery 1-4 through wires.

[0020] Working principle:

[0021] When using this device, the divider base plate 1-1 is fixedly connected to the front end of the harvester. Multiple units can be used together. This device converts solar energy into DC power through solar panels 1-6. After the voltage / current is regulated by the controller 1-5, the power is stored in the battery 1-4. During use, the electric telescopic rod 3-2 is extended by the PLC controller, which in turn drives the grass barrier 2-1 to rotate and unfold outward. The angle of the grass barrier 2-1 can be adjusted by adjusting the extension length of the electric telescopic rod 3-2, which can be adjusted according to the type of crop being harvested and the row spacing. The PLC controller controls the drive... When the motor 2-2 is energized, it drives the mowing wheel 2-3 to rotate. When the harvester moves to harvest, the divider base plate 1-1 can lift up the upright or fallen crop stalks, while the weed baffle 2-1 blocks the weeds. As the harvester moves, the arc-shaped cutter on the mowing wheel 2-3 can cut the weeds, causing them to fall onto the field ridge. This avoids the problem of weeds accumulating on the divider and affecting the division of crops, as well as the problem of pushing and pressing on the crops in front. The retraction of the electric telescopic rod 3-2 can reset the weed baffle 2-1.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
