Description

Technical Field

[0001] The utility model relates to the field of harvesters, in particular to a high-efficiency harvesting platform. Background Art

[0002] A corn harvester is an agricultural machine that mechanically removes mature corn ears, stacks them, and returns the stalks to the field. The harvester's header (also known as the harvesting or picking table) is a key component of the machine. After cutting, the header uses a series of rollers, chains, and other mechanical structures to guide the corn plants in a specific direction, effectively separating the ears from the plants and collecting them in a container inside the machine.

[0003] The design and performance of the header directly affect the efficiency of the entire harvester. An efficient header can reduce losses while increasing harvesting speed, ensuring that farmers can complete the harvesting work within the optimal time.

[0004] The front end of the soft board is flat or has a forward guiding edge. When the corn plant passes between the ear picking roller 1 and the ear picking roller 2, the front end of the soft board is lifted by the plant. When the harvesting speed increases to a higher value, the passage of the corn plant between the ear picking roller 1 and the ear picking roller 2 will be blocked, limiting the improvement of the harvesting efficiency.

[0005] The soft plate pressure plate adopts a flat plate structure to press on the soft plate. The contact part between the soft plate and the soft plate pressure plate is compressed and deformed, and the non-contact part is lifted up, resulting in a gap between the soft plate and the ear picking roller. When the harvesting speed increases to a higher value, corn kernels are lost from the gap, the loss rate increases, and the improvement of harvesting efficiency is limited. Utility Model Content

[0027] Example: As shown in the attached Figure 1 To the attached Figure 8 As shown, a high-efficiency harvesting platform includes a frame, on which a drive box and a straw divider are installed, the drive box is used to drive the straw divider to work, and the straw divider includes a shell 01, an ear picking roller 1, an ear picking roller 2, a seat plate 3, a soft plate 4 and a soft plate pressure plate 5. It should be noted that the connection method between the ear picking roller 1, the ear picking roller 2, the seat plate 3, the soft plate 4 and the soft plate pressure plate 5 and the frame belongs to the prior art, so the specific connection method is no longer repeated. A corn plant channel is formed between the ear picking roller 1 and the ear picking roller 2, and the front end of the soft plate 4 is arranged at the bottom of the seat plate 3, and the front end of the soft plate 4 is pressed under the seat plate 3. In most models currently on the market, the front end of the soft plate 4 is not pressed under the seat plate 3, resulting in the corn plant pushing up the front end of the soft plate 4 during harvesting, causing the channel to be blocked.

[0028] The soft board 4 is fixedly mounted on the frame via a soft board pressing plate 5. Both sides of the soft board 4 close to one end of the seat plate 3 are provided with guide edges inclined backward. The soft board pressing plate 5 includes a fastening section 51 and a bending section 52. The fastening section 51 and the bending section 52 are fixedly connected. A bending portion is provided between the fastening section 51 and the bending section 52, and the bending section 52 is provided toward the soft board 4.

[0029] The front end of the soft board 4 is modified into a backward-sloping guide edge and pressed under the base plate 3. This creates a smooth path for the corn plants and no longer limits harvesting efficiency. The front end of the soft board 4 is modified into a backward-sloping guide edge and pressed under the base plate 3. This adjustment creates a smooth path for the corn plants and no longer limits harvesting efficiency.

[0030] The backward-tilted guide edge better guides the corn plants into a specific channel, reducing obstructions and jams during entry. When the front end of the soft board 4 presses beneath the base plate 3, the stability and continuity of the channel are further ensured. Corn plants can more smoothly pass through this channel and enter the subsequent harvesting process. This makes the harvesting process more efficient and smoother, greatly improving harvesting efficiency. At the same time, the limitations of the soft board 4 on harvesting efficiency are eliminated, significantly improving corn harvesting operations.

[0031] A small bend is added to the soft plate pressure plate 5, with the bend facing the soft plate 4. When the soft plate 4 and the soft plate pressure plate 5 come into contact, the contacting portion undergoes compression deformation. The uncontacted portion of the soft plate 4, squeezed by the bent portion of the soft plate pressure plate 5, cannot tilt. This design effectively prevents the formation of a gap between the soft plate 4 and the ear-picking roller 1. By eliminating this gap, the loss rate of the corn harvester can be significantly reduced, and the soft plate 4 no longer limits harvesting efficiency.

[0032] The added bending design makes the action of the soft plate pressure plate 5 on the soft plate 4 more precise and effective. The compression deformation of the contact portion can increase the fit between the two and improve stability. The non-contact portion remains flat under the pressure of the bending portion, preventing the formation of gaps. In this way, during the corn harvest process, the corn ears can be handled more smoothly by the ear picking roller 1, reducing the loss of corn caused by gaps. Reducing the loss rate not only improves the economic benefits of the harvest, but also ensures the efficient harvesting operation, bringing tangible benefits to corn growers and agricultural production.

[0033] The frame is equipped with several groups of ear picking rollers 1, ear picking rollers 2, seat plates 3, soft plates 4 and soft plate pressure plates 5. The frame is fixed with a seat plate reinforcement plate 6, which is arranged at the bottom of the seat plate 3. The seat plate reinforcement plate 6 is used to increase the stability of the seat plate 3.

[0034] The fastening section 51 is provided with a plurality of bolt holes, and the fastening section 51 is fixed to the frame by bolts.

[0035] The fastening section 51 is provided with several bolt holes. Bolts securely fasten the fastening section 51 to the frame. This connection ensures a stable connection between the fastening section 51 and the frame, allowing it to withstand certain forces without loosening or displacement during equipment operation. The multiple bolt holes allow the fastening section 51 to be adjusted in position to suit different installation requirements and operating scenarios. Furthermore, the bolt connection offers the advantage of easy disassembly, facilitating maintenance or component replacement.

[0036] The fastening section 51 and the bending section 52 are integrated into one piece. This integrated arrangement can effectively increase the integrity and durability of the soft board pressure plate 5. Since the fastening section 51 and the bending section 52 are integrated into one piece, they can work together better when subjected to force, evenly distributing the force to the entire soft board pressure plate 5, thereby reducing the occurrence of local stress concentration. At the same time, the integrated arrangement also improves the durability of the soft board pressure plate 5. Compared with a split design, the integrated soft board pressure plate 5 is less likely to experience problems such as loosening and damage at the connection parts during long-term use. It can better withstand various forces and wear during the operation of the equipment, extend the service life of the soft board pressure plate 5, and ensure the stable operation and efficient work of the equipment.

[0037] A positioning sleeve 61 is fixedly installed on the seat plate reinforcement plate 6, and a positioning hole 31 is opened on the seat plate 3. The positioning sleeve 61 and the positioning hole 31 are correspondingly arranged. Each seat plate 31 is correspondingly provided with two seat plate reinforcement plates 6, and each seat plate reinforcement plate 6 is provided with two positioning sleeves 61.

[0038] The ear picking roller 1, ear picking roller 2, seat plate 3, soft plate 4 and soft plate pressure plate 5 are all arranged at the bottom of the shell 01, and the shell 01 is arranged to be raised upward; the shell 01 is arranged in an upward raised shape. This structural design has many advantages. On the one hand, arranging the key components at the bottom of the shell can provide them with stable support and protection, ensuring that the various components can operate normally during the corn harvesting process. On the other hand, the upward raised design of the shell may be to form a certain space inside to accommodate and arrange various mechanical structures, and it also helps to guide the flow direction of the corn plants and improve the harvesting efficiency. In addition, this design can also prevent external debris from entering the interior of the equipment to a certain extent and interfering with the normal operation of the equipment.

[0039] The housing 01 includes a front shell 010 and a rear shell 012 . The front shell 010 and the rear shell 012 are fixedly connected. A guide cone 011 is provided at one end of the front shell 010 away from the rear shell 012 .

[0040] The ear picking roller 1 , the ear picking roller 2 2 , the soft plate 4 and the soft plate pressing plate 5 are arranged at the bottom of the rear shell 012 , and the seat plate 3 is arranged at the bottom of the front shell 010 .

[0041] The housing 01 is composed of a front housing 010 and a rear housing 012, which are fixedly connected. A guide cone 011 is installed at the end of the front housing 010 away from the rear housing 012. The guide cone can play a guiding role during the operation of the device, ensuring that the corn plants enter the device smoothly.

[0042] The first and second ear picking rollers (1, 2), the soft plate (4), and the soft plate pressure plate (5) are all located at the bottom of the rear housing (012). The first and second ear picking rollers (2) work together to remove the ears of corn. The soft plate (4) and the soft plate pressure plate (5) ensure the stability of the corn plants during the harvesting process. The base plate (3) is located at the bottom of the front housing (010), providing support for the equipment and ensuring a smooth corn harvest.
