Description

Technical Field

[0001] This utility model relates to the field of corn harvesters, and in particular to a corn harvester grain tipping device. Background Technology

[0002] An existing patent (publication number: CN215074004U) proposes a grain recovery device for a corn harvester, including a fixed frame and a hopper. Limiting guide rails are provided on the left and right sides of the top of the fixed frame, and the hopper is slidably mounted on the top of the fixed frame. However, this device requires manual operation of the pull rod to "pull out the hopper and open the movable baffle when it is necessary to discharge the grains in the hopper". The operation process consumes more manpower, thus affecting the convenience and efficiency of grain recovery. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a corn harvester grain tipping device that, during the corn harvesting process, automatically tipes the corn grain collection bucket through the linkage of a tipping hydraulic cylinder, a main support connecting rod, and a limit connecting rod, thereby enabling the corn grain collection bucket to automatically empty its contents. This makes the corn grain recycling process faster and increases the efficiency of corn grain recycling.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A corn harvester grain tipping device includes a corn grain storage bin, a main support connecting rod, a storage bin mounting platform, a tipping drive hydraulic cylinder, and a limiting connecting rod. The storage bin mounting platform has an agricultural machinery mounting platform on one side and a lower main connecting rod mounting platform on the other side. A lower connecting rod mounting platform is located at the top of the storage bin mounting platform. The lower connecting rod mounting platform has a lower limiting rod connection hole and a lower hydraulic cylinder connection hole at its top. The lower limiting rod connection hole is located on the side of the lower hydraulic cylinder connection hole closest to the lower main connecting rod mounting platform. A corn grain storage bin is mounted on the top of the storage bin. The side of the corn grain storage bin facing the lower main connecting rod mounting platform has a side reinforcing rod and a connecting rod mechanism mounting groove. The side reinforcing rod is located at the top of the connecting rod mechanism mounting groove, and the top of the connecting rod mechanism mounting groove has an upper reinforcing plate.

[0006] The upper reinforcing plate has an upper main connecting rod mounting platform on the side near the lower main connecting rod mounting platform. The upper reinforcing plate has an upper hydraulic cylinder connecting rod inside. The connecting rod mechanism mounting groove is provided with a main support connecting rod. The bottom of the main support connecting rod has a lower main connecting rod mounting head, which is rotatably connected to the lower main connecting rod mounting platform. The top of the main support connecting rod has an upper main connecting rod mounting head, which is rotatably connected to the upper main connecting rod mounting platform. The side of the main support connecting rod near the lower connecting rod mounting platform has a limit rod connecting platform.

[0007] The limiting rod connecting platform has an upper limiting rod connecting groove inside. The lower connecting rod mounting platform is provided with a limiting rod at the top.

[0011] 3. The corn kernel storage bucket of this utility model is provided with a side reinforcing rod on the side. The side reinforcing rod can increase the overall strength of the corn kernel storage bucket, and can also increase the structural strength of the connection point between the upper hydraulic cylinder connecting rod and the upper hydraulic cylinder connecting sleeve, and the connection point between the upper main connecting rod mounting platform and the upper main connecting rod mounting head, thereby avoiding deformation of the corn kernel storage bucket during the tipping process and ensuring the stability when storing kernels.

The side of the main support connecting rod 6 near the lower connecting rod mounting platform 12 has a limiting rod connecting platform 20.

[0024] Example 3:

[0025] The limiting rod connecting platform 20 of this utility model has an upper limiting rod connecting groove 21 inside, and a limiting connecting rod 23 is provided on the top of the lower connecting rod mounting platform 12. The main support connecting rod 6, the tipping bucket drive hydraulic cylinder 17, and the limiting connecting rod 23 are all set inside the connecting rod mechanism mounting groove 2. When the corn kernel collecting bucket 1 is in the kernel receiving state, the appearance of this device is more regular, reducing the space occupied by this device and reducing the burden when connecting agricultural machinery to this device. The bottom of the limiting connecting rod 23 has a lower limiting rod connecting head 15, which is rotatably connected to the lower limiting rod connecting hole 13. The top of the limiting connecting rod 23 has an upper limiting rod connecting slider 22, which is adapted to the upper limiting rod connecting groove 21.

[0026] Example 4:

[0027] The upper limit rod connecting slider 22 of this utility model is connected to the upper limit rod connecting groove 21.

The upper hydraulic cylinder connecting sleeve 19 is rotatably connected to the upper hydraulic cylinder connecting rod 18.

[0030] Example 6:

[0031] The installation steps of this utility model are as follows: Rotately connect the lower hydraulic cylinder connector 16 of the tipping bucket drive hydraulic cylinder 17 to the lower hydraulic cylinder connection hole 14 of the storage bucket mounting platform 11; rotately connect the upper hydraulic cylinder connecting sleeve 19 of the tipping bucket drive hydraulic cylinder 17 to the upper hydraulic cylinder connecting rod 18 of the corn kernel storage bucket 1; rotately connect the lower main connecting rod mounting head 8 of the main support connecting rod 6 to the lower main connecting rod mounting platform 9 of the storage bucket mounting platform 11; rotately connect the upper main connecting rod mounting head 7 of the main support connecting rod 6 to the upper main connecting rod mounting platform 5 of the corn kernel storage bucket 1; rotately connect the lower limit rod connector 15 of the limiting connecting rod 23 to the lower limit rod connection hole 13 of the storage bucket mounting platform 11; insert the upper limit rod connecting slider 22 of the limiting connecting rod 23 into the upper limit rod connecting groove 21 of the main support connecting rod 6. The installation of this device is now complete.

[0032] The working steps of this utility model are as follows: After the corn kernels are fed into the corn kernel storage bin 1 by the harvester and the bin 1 is full, the tipping hydraulic cylinder 17 extends, and the corn kernel storage bin 1 tilts. At this time, the upper limit rod connecting slider 22 slides inside the upper limit rod connecting groove 21 until the upper limit rod connecting slider 22 slides to the end of the upper limit rod connecting groove 21. Then, the upper limit rod connecting slider 22 is locked at the end of the upper limit rod connecting groove 21. At this time, the main support connecting rod 6 tilts to the extreme position. As the tipping hydraulic cylinder 17 continues to extend, the tilt angle of the corn kernel storage bin 1 gradually increases until the opening of the corn kernel storage bin 1 faces downward and the corn kernels are poured out.
