Description

Technical Field

[0001] The utility model belongs to the technical field of a combine harvester header, in particular to a soybean header for a combine harvester. Background Art

[0002] A combine harvester is a highly integrated agricultural machine that can complete multiple steps of harvesting, threshing, separating stems, and removing debris from grain crops at one time, harvesting grains directly from the field. This machine greatly improves agricultural production efficiency and reduces manpower requirements. It is widely used in the harvesting of crops such as wheat, rice, and soybeans. The soybean header for a combine harvester is an accessory or component designed specifically for harvesting soybeans. It is installed at the front end of the combine harvester and is responsible for cutting and transporting soybean plants into the machine for subsequent threshing, separation, and other operations. It usually needs to adapt to the specific growth habits and plant structure of soybeans to ensure harvesting efficiency and reduce losses.

[0003] The gathering frame of the existing soybean harvester for combine harvesters (the part responsible for gathering and guiding crops into the threshing device) cannot adjust the gathering angle. Due to the different planting densities and growth conditions of different soybeans, the fixed gathering angle may not be able to effectively cope with all situations, resulting in some crops left in the field, causing waste, and also leading to low harvesting efficiency or increased crop losses under certain conditions. When the crops are densely packed or severely lodging, the non-adjustable gathering frame may find it difficult to smoothly guide the crops into the threshing device. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies in the prior art and provides a soybean harvesting platform for a combine harvester. The angle of the gathering frame can be adjusted, and the most suitable gathering angle can be adjusted according to the specific height, density and growth conditions of the soybean plants, thereby optimizing the harvesting effect and reducing missed harvests. It can maintain a high harvesting efficiency under various field conditions, reduce blockages and speed up the operation.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a soybean harvesting platform for a combine harvester, including a harvesting platform, a harvesting piece is arranged on the front side of the harvesting platform, the interior of the harvesting platform is rotatably connected to a rotating frame through a rotating shaft, a sprocket wheel 1 is arranged on the right end of the rotating shaft, the interior of the harvesting platform is rotatably connected to a collecting roller located on the rear side of the rotating frame, a sprocket wheel 2 is arranged on the right end of the collecting roller, and adjustable angle gathering mechanisms are respectively arranged on the left and right sides of the harvesting platform, and a dust removal mechanism is arranged on the upper end of the harvesting platform. The adjustable angle gathering mechanism includes a dust removal mechanism arranged on the left and right sides of the harvesting platform respectively through a rotating column. A gathering frame, a plurality of pillars are arranged at the lower ends of the two gathering frames, rotating columns are arranged on the left and right sides of the upper end of the harvesting platform, pull plates are arranged on the outer arc surfaces of the two rotating columns, locking columns are arranged on the lower ends of the two pull plates, and perforated disks are arranged on the upper ends of the two rotating columns, the two locking columns are respectively plugged into one of the holes inside the adjacent perforated disks, and limiting disks are arranged on the upper ends of the two locking columns, an elastic driving unit is arranged between the pull plate and the limiting disk, the elastic driving unit includes a spring arranged between the pull plate and the limiting disk, and the two springs are respectively sleeved on the corresponding outer arc surfaces of the rotating columns.

[0006] As a further improvement of the present invention, a mounting shell is provided at the rear side of the harvesting platform, and a plurality of mounting holes are provided inside the mounting shell.

[0007] As a further improvement of the utility model, the dust removal mechanism includes two collecting shells rotatably arranged on the upper end of the harvesting platform through a connecting column, and cavity frames are arranged in the slots opened at the upper ends of the two collecting shells. An electric drive unit for driving the connecting column to rotate is arranged on the left side of the harvesting platform. The electric drive unit includes a motor arranged on the left side of the harvesting platform, and the output shaft of the motor is connected to the electric drive unit for rotating the connecting column through a coupling.

[0008] As a further improvement of the utility model, a control panel is provided on the right side of the harvesting platform, and the motor is electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, by installing the header on the harvester, and then connecting sprocket one and sprocket two to the drive chain of the harvester through chains, the collecting roller and the rotating frame rotate, and the harvester drives the header forward. The harvesting parts cut off the bottom of the soybean straw, and the gathering frames on both sides can guide the soybean straw to the header. At the same time, the rotating frame rotates to roll in the soybean straw, and the harvested soybean straw is collected by the collecting roller and transported to the inside of the harvester through the conveying mechanism of the harvester, so that the soybean harvesting can be completed quickly.

[0011] Secondly, by pulling the pull plate, the locking column is allowed to leave the hole of the perforated disk, and then the personnel can rotate the gathering frame to adjust its angle. After rotating to the appropriate angle, the pull plate is released, and the spring quickly rebounds to drive the locking column to be inserted into a hole of the perforated disk to quickly lock the gathering frame, thereby completing the adjustment of the gathering frame angle. The gathering frame angle can be adjusted, and the most appropriate gathering angle can be adjusted according to the specific height, density and growth conditions of the soybean plants, thereby optimizing the harvesting effect and reducing missed harvesting. It can maintain a high harvesting efficiency under various field conditions, reduce blockages, and speed up operations.

[0012] Thirdly, the dust collection mechanism of the harvester can be connected to the outside of the cavity frame, so that the dust generated during the harvesting of soybean straw can be collected through the collection cover to prevent the dust from blocking the harvester driver's line of sight. The motor can also be turned on through the control panel, and the rotation of the output shaft can drive the collection cover to rotate, thereby increasing the dust collection range.

[0013] Fourthly, the mounting holes on the mounting shell can facilitate personnel to install the soybean header on the harvester, making the installation faster. BRIEF DESCRIPTION OF THE DRAWINGS
