Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a harvester header and a harvester. Background Art

[0002] During the harvesting of crops, the types of crops planted and the growth conditions of crops in different regions are different. During the harvesting of crops, it is often necessary to adjust the harvesting machinery. When harvesting different types of crops, it is often necessary to replace the harvester to adapt to different crops. In addition, for the different growth trends of the same crop, it is also necessary to replace different types of harvesters for harvesting. For example, when the stems of crops are too long, they need to be harvested with a harvester equipped with a fling knife; when crops fall over, they need to be harvested with a harvester with a long-pointed divider. This is the case for the same crops, and different regions often plant multiple types of crops. Therefore, the investment cost of agricultural harvesting machinery is also a considerable expense. At the same time, some harvesting platforms are too large in size, and when they are transferred from the harvester body, there are problems of unsafe and difficult transfer. Usually, the harvesting platform is disassembled and then transferred. At this time, a simple and easy-to-hook harvesting platform is urgently needed.

[0003] In the existing agricultural harvesting machinery, each harvesting machinery is equipped with a header. Therefore, it is necessary to provide a replaceable and easy-to-install harvester header to overcome the above-mentioned defects. Utility Model Content

[0034] The harvester is divided into a machine body and a header. During the operation of the harvester, the machine body provides power for the header, which divides the stems and ears of crops and transports them to the machine body for further processing or storage. The header is mounted on the machine body through a frame 50 set on the machine body. Due to the complex structure and heavy weight of the header, it is difficult to mount it. When dealing with different harvesting situations, a lot of harvesting time is often consumed due to replacing the header, which affects the progress of the harvesting operation. Therefore, it is urgent to install a simple header structure to reduce the difficulty of header installation and improve the progress of the harvester operation.

[0035] See also Figures 1 to 5 As shown, the embodiment of the present application provides a header of a harvester, the header is hung at the front end of a frame 50, and includes a hanging mechanism 10 for connecting the header and the frame 50, and the hanging mechanism 10 includes:

The connecting seat 102 includes a fixing portion 1021 and a hanging portion 1022, and the fixing portion 1021 and the hanging portion 1022 are connected in a snap-fit ​​manner. When the fixing portion 1021 and the hanging portion 1022 are snap-fitted, a hanging hole 103 is formed, and the hanging hole 103 cooperates with the hanging pipe 101, and the header is hung on the frame 50. When the cutting table is hung on the frame 50, the hanging tube 101 is in the state of passing through the hanging hole 103, and the fixing part 1021 cooperates with the hanging part 1022 to press against the hanging tube 101, that is, the fixing part 1021 presses against the arc surface on one side of the hanging hole 103, and the hanging part 1022 presses against the arc surface on the other side of the hanging tube 101, thereby realizing the hanging of the cutting table. At the same time, the cutting table can rotate up and down around the axial position of the hanging tube 101.

[0040] The use of this type of mounting structure can simplify the installation process of the harvester header, save the installation time of the harvester header, and facilitate the installation of the harvester header.

In order to make the hanging pipe 101 more firmly fixed on the front end of the frame 50, the first mounting plate 1011 and the second mounting plate 1012 are provided to connect the hanging pipe 101 and the frame 50. The first mounting plate 1011 is arranged on the outer side of the beam where the frame 50 fixed to the hanging tube 101 is located, and the second mounting plate 1012 is arranged on the inner side of the beam where the bracket fixed to the hanging tube 101 is located. The first mounting plate 1011 and the second mounting plate 1012 are fixed to the frame 50 by welding. At the same time, the first mounting plate 1011 is provided with a first limiting hole 1011a, and the second mounting plate 1012 is provided with a second limiting hole 1012a.

The hanging part 1022 and the fixing part 1021 are connected around the hanging tube 101, and the header of the harvester rotates around the hanging tube 101. Specifically, when the header is hung, the hanging hole 103 is formed when the hanging part 1022 and the fixing part 1021 are connected, and the hanging tube 101 is arranged in the hanging hole 103, and the header of the harvester rotates around the hanging tube 101.

[0044] Preferably, the fixing portion 1021 is provided with two opposite first through holes 1021c, and the hanging portion 1022 is provided with two opposite second through holes 1022c. When the fixing portion 1021 is connected with the hanging portion 1022, the pin passes through the first through hole 1021c and the second through hole 1022c. The first through hole 1021c is provided on the fixing portion outer wall 1021b, and the second through hole 1022c is provided on the hanging portion connecting wall 1022b.

[0045] Preferably, the connection seat 102 is arranged on the first bracket 104, and the first bracket 104 is arranged at the rear end of the header of the harvester, and is used to hook the header and the frame 50. In order to make the header rotate smoothly around the hook pipe, the connection seat 102 is fixed to the header through the first bracket 104, and one end of the first bracket 104 is welded to the header, and the other end is welded to the connection seat 102.

[0046] Preferably, with the forward direction of the harvester as the front, a hooking mechanism 10 is respectively provided on the left and right sides of the header. In order to stably hook the header to the front end of the frame 50, at least one hooking mechanism 10 is respectively provided on the left and right sides of the header to achieve stable hooking between the header and the machine body, thereby improving hooking reliability and safety.

The bearing can be installed on the bearing mounting seat 21 arranged on the first mounting plate 1011, and when the position of the cutting platform transmission shaft 20 is limited, the bearing can also drive the rotation of the cutting platform transmission shaft 20, thereby driving the internal mechanisms of the cutting platform to work. With this arrangement, the transmission effect of the cutting platform is better.

[0048] Preferably, the header also includes a safety bracket 30 and a cylinder 40. The cylinder 40 connects the header and the harvester frame 50 to provide the header with rotation power. The safety bracket 30 is arranged at one end where the cylinder 40 is connected to the header of the harvester to limit the position of the cylinder 40. Specifically, the cylinder 40 provides power for the rotation and lifting of the header by extending forward. During the installation and maintenance of the harvester header, after the rotation and lifting action command is stopped, the header will suddenly fall back and lower, which will bring safety hazards. To avoid this situation, a safety bracket 30 is arranged at one end where the cylinder 40 is connected to the header of the harvester. Under normal working conditions, the safety bracket 30 is connected to the header. When the header is replaced or repaired, the safety bracket 30 is lowered, and the position of the cylinder 40 is limited by the safety bracket 30 to prevent the cylinder 40 from retracting and the header from suddenly falling. Through this arrangement, the safety of the header installation and maintenance process is improved.
