Description

Technical Field

[0001] The invention relates to the technical field of wheat harvester header leveling, in particular to a transverse leveling mechanism of a backpack wheat harvester header device. Background Art

[0002] Foreign enterprises and research institutes started the research and development of hilly and mountainous tractors early, and developed hilly and mountainous harvesters with their own characteristics. For example, the TT270 produced by the Swiss Aeb i company has better performance, which has good traction and adhesion performance and off-road performance, but lacks the stability and terrain adaptability required for hilly and mountainous agricultural production, and the model is too large to adapt to the agricultural natural conditions of narrow roads and small plots in my country's hilly and mountainous areas. Although the current mountain grain combine harvesters abroad are advanced, they are too large and expensive, which are not suitable for the agricultural natural conditions of narrow roads and small plots in my country's hilly and mountainous areas and the economic conditions of low purchasing power of farmers in mountainous areas.

[0003] The development of domestic hilly and mountainous grain combine harvesters is in its infancy. Most of the products currently developed are small in size and low in price, and are used by many farmers in hilly and mountainous areas in my country. However, they have the disadvantages of high operating intensity, single function, and easy rollover and side sliding. At present, when general power machinery is operating in hilly and mountainous areas with large slopes such as the Loess Plateau in the northwest and the southwest, it is more likely to roll over and slide due to the large slope. Therefore, in order to prevent problems such as side sliding and rollover, we propose a lateral leveling mechanism for the header device of a backpack wheat harvester. Summary of the invention

A support 18 and a support 20 are arranged on both sides of the middle part of the top surface of the extension plate 23, and the two supports can be driven by the threaded rod to slide along the extension plate 23, thereby realizing flexible position adjustment by changing the position of the supports to adapt to different leveling requirements. The tops of the support 18 and the support 20 are respectively movably connected to the hydraulic cylinder 17 and the hydraulic cylinder 2 19, and the output ends of the hydraulic cylinder 17 and the hydraulic cylinder 2 19 are respectively rotatably connected to the two sides of the bottom of the threshing device 6.

At the same time, the leveling angle range is further expanded by motor adjustment, thereby improving the terrain adaptability and operating efficiency of the equipment.

[0046] Please refer to the attached Figure 2 and Figure 3 A threshing iron plate 8 is provided on one side of the threshing device 6 close to the cutting table device 4. One side of the conveying device 5 is connected to the cutting table iron plate 7 through a connecting mechanism 1 9, and the other side of the conveying device 5 is connected to the threshing iron plate 8 through a connecting mechanism 2 14.

[0047] In the present invention, a threshing iron plate 8 is installed on the side of the threshing device 6 close to the cutting table device 4, which is used to connect with the conveying device 5 and maintain structural stability. One end of the conveying device 5 is fixedly connected to the cutting table iron plate 7 of the cutting table device 4 through a connecting mechanism 1 9, ensuring that the materials harvested by the cutting table device 4 can be smoothly transmitted to the inside of the conveying device 5. The other end of the conveying device 5 is connected to the threshing iron plate 8 of the threshing device 6 through a connecting mechanism 2 14.

[0048] Please refer to the attached Figure 8 The conveying device 5 includes an iron plate 1 36, an iron plate 2 37, an iron plate 3 38 and an iron plate 4 39, and the four same sides are respectively connected with angle iron 1 32, angle iron 2 33, angle iron 34 and angle iron 4 35, and the iron plates 1 36, 37, 38 and 39 are interconnected to form a closed pipeline, and the two sides of the iron plates 1 36, 37, 38 and 39 are fixedly connected with angle iron 1 32, angle iron 2 33, angle iron 34 and angle iron 4 35.

[0049] In the present invention, the conveying device 5 is composed of an iron plate 1 36, an iron plate 2 37, an iron plate 3 38 and an iron plate 4 39, and they are interconnected to form a complete closed pipeline for conveying materials. Angle irons are fixedly connected to both sides of each iron plate, wherein the same side of iron plates 1 36 to 4 39 is respectively connected with angle iron 1 32, angle iron 2 33, angle iron 3 34 and angle iron 4 35, which not only enhance the structural strength of the conveying device 5, but also ensure the overall rigidity and stability. And through this closed pipeline design, the conveying device 5 can effectively carry and transmit the materials discharged by the cutting table device 4, and smoothly convey them to the threshing device 6. The close connection between the iron plate and the angle iron improves the sealing during the conveying process, prevents the material from scattering or leaking, adapts to the requirements of efficient material transmission under different operating conditions, and further optimizes the operating performance of the entire harvester.

[0050] Please refer to the attached Figure 8 and Fig. 9 The connecting mechanism 9 includes a cover plate 10, which is connected to angle iron 1 32, angle iron 2 33, angle iron 34 and angle iron 4 35 on one side of the conveying device 5 through bolts 24 and nuts 25, and one side of the cover plate 10 is movably connected to one side of the cutting table iron plate 7.

[0051] In the present invention, the connection mechanism 9 is composed of a cover plate 10, which is fixedly connected to the angle iron 1 32, angle iron 2 33, angle iron 3 34 and angle iron 4 35 on one side of the conveying device 5 by bolts 24 and nuts 25, ensuring the firmness and reliability of the connection. At the same time, one side of the cover plate 10 is movably connected to the cutting table iron plate 7 of the cutting table device 4, so that the cutting table device 4 and the conveying device 5 have a certain flexibility, which is convenient for adjusting the position or angle under different terrain conditions. Thus, it can adapt to the terrain changes in complex working environments.

[0052] Please refer to the attached Fig.10 The connecting mechanism 14 includes a cover plate 15, which is movably connected to the threshing iron plate 8. A hole is opened in the middle of the cover plate 15. The conveying device 5 installs the angle iron 1 32, the angle iron 2 33, the angle iron 34 and the angle iron 4 35 on the other side of the conveying device 5 in the hole through the bolt 26 and the nut 27.

[0053] In the present invention, the cover plate 15 is movably connected to the threshing iron plate 8 of the threshing device 6, providing a certain flexibility to adapt to different working conditions and avoiding loosening or failure of the connection caused by equipment vibration or terrain changes. A hole is designed in the middle of the cover plate 15, through which the material between the conveying device 5 and the threshing device 6 is smoothly transferred.

[0054] Please refer to the attached Figure 7 and Fig.11The motor 1 21 and the motor 2 22 are both fixedly connected to the top surface of the extension plate 2 3 by bolts 3 28 and nuts 3 29. A stripping concave screen plate is installed inside the threshing device 6, and an opening is provided on one side of the stripping concave screen plate, and a leak-proof iron plate 23 is provided below the opening of the stripping concave screen plate. The leak-proof iron plate 23 is fixedly connected to the bottom of one side of the cover plate 2 15, and the threshing concave screen 16 is fixedly connected to the threshing iron plate 8 by bolts 4 30 and nuts 4 31.

[0055] In the present invention, motor 1 21 and motor 2 22 are both firmly fixed on the top surface of extension plate 2 3 by bolt 3 28 and nut 3 29, which not only ensures the firmness of the motor installation, but also effectively reduces the impact of equipment vibration or external force impact during operation on the stability of the motor.

[0056] Working principle: When in use, when it is necessary to adjust the posture of the cutting table device 4, the output end is extended by driving the hydraulic cylinder 12. At this time, the hydraulic cylinder 12 can be used to push the shaft 11, and the hydraulic cylinder 12 and the shaft 11 are rotatably connected, so the cutting table iron plate 7 of the cutting table device 4 can be driven to operate, so that the cutting table iron plate 7 rotates around the rotating shaft composed of the connecting mechanism and the cover plate 10, thereby driving the overall leveling of the cutting table. When it is necessary to adjust the posture of the threshing device 6, the leveling method is selected according to the direction in which the posture needs to be adjusted. When the threshing device 6 is away from the hydraulic cylinder 2 19 and close to the hydraulic cylinder 17, the pressure of the hydraulic cylinder 17 is set to zero, and then the hydraulic cylinder 2 19 is controlled to contract, so that the threshing device 6 rotates along the output end of the hydraulic cylinder 17 as the rotating axis, so that it is close to the hydraulic cylinder 2 19, thereby achieving leveling. Purpose, otherwise the hydraulic cylinder 17 is driven to retract the output end. When the inclination angle to be adjusted is too large and the telescopic stroke of the hydraulic cylinder 12 cannot meet the leveling of the current working state, the motor 1 21 and the motor 2 22 can be started to run, that is, when the threshing device 6 is too far away from the hydraulic cylinder 19, at this time, if the stroke of the hydraulic cylinder 19 is completely retracted and is not enough to make the threshing device 6 in a horizontal state, the motor 22 is driven to rotate the threaded rod, and the support 20 is driven by the threaded rod to move toward the middle of the extension plate 2 3. At this time, the support 20 is close to the middle of the threshing device 6, so the fulcrum position of the hydraulic cylinder 19 is adjusted, and then the threshing device 6 is pulled to a horizontal state, thereby increasing the maximum angle of the threshing device 6 that can be tilted and leveled, so as to achieve the leveling of the threshing device 6 in the tilted state required for leveling, otherwise the motor 1 21 is driven to run.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
