Abstract
Description
Technical Field
[0001] The utility model relates to the field of agricultural machinery, in particular to a thresher structure capable of switching between the states of returning debris to a screen surface and returning to a drum. Background Art
[0002] In recent years, the level of agricultural mechanization in my country has been continuously improving. For crops such as wheat and rice (depending on the variety) that have fewer impurities during re-threshing and are easy to thresh, the machine can choose a debris return screening surface structure for debris re-threshing during harvesting to improve work efficiency; for millet, sorghum, and some varieties of crops that are difficult to thresh, when using the debris return screening surface structure, the debris re-threshing effect is poor, and a large amount of debris is likely to accumulate on the screen surface, resulting in poor cleaning and high losses. At this time, a machine with a debris return drum structure is selected, which can extend the screening process during re-threshing, improve the threshing capacity, and enhance the cleaning effect; some areas or cross-regional users have the need to adjust the debris re-threshing structure during harvesting, but the re-threshing structure of the machines on the market has been determined when they leave the factory and cannot be changed.

[0014] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0015] See also Figure 1 and Figure 2The embodiment of the present invention provides a thresher structure that can switch the waste re-threating back to the screen surface and back to the drum state, including a thresher body, on which a second waste auger device 4, a baffle 5, a drive assembly 6 and a second roller cover 7 are respectively installed. The second roller cover 7 includes a cover plate and a re-threating device. The re-threating device is installed in the front position of the cover plate, and the cover plate is fixedly installed on the upper side of the thresher body. The drive assembly 6 is installed on the left side of the thresher body and is respectively connected to the separation drum and the re-threating device on the thresher body. The thresher drives the drive assembly 6 and the re-threating device to operate. The second waste auger device 4 is installed on the lower part of the thresher body, and the second waste auger device 4 is connected to the re-threating device through a pipeline. The baffle 5 is installed on the nozzle of the thresher.
[0016] The driving assembly 6 includes a pulley and a tensioning wheel. The pulley is installed on the threshing drum of the thresher body and is connected to the re-thresher device through a belt. The tensioning wheel is rotatably connected to the left side of the thresher body and tensions the belt.
[0017] During use, the utility model:
[0018] like Figure 4 The figure shows a thresher with the debris returning to the screen surface. At this time, the secondary threshed materials fall from the top of the vibrating screen as shown in the arrow. First, remove the first debris auger device 1 (return screen surface), the spacer 2 on the rear side of the threshing drum for protecting the keyway, and the first drum cover 3. Figure 3 As shown, the baffle 5 is then covered on the nozzle of the original waste return screen structure for connecting the waste auger and the thresher, and then the second waste auger device 4 (return drum), the second drum cover 7 with the re-threshing device and the drive assembly 6 for driving the drum cover re-threshing device are assembled to the machine. The assembled thresher is replaced with the waste return drum structure, as shown in FIG. Figure 1 As shown, the secondary desorbed material falls from the front end of the drum cover as shown in the arrow. Figure 2 shown.
[0019] During this process, the mounting holes of the drum cover on the backpack remain unchanged. The pulley and tensioner used to drive the drum re-threshing device are protected by the keyway of the pulley when not in use by the spacer 2, which also ensures the installation position of other parts. The tensioning seat required by the tensioner has been pre-welded to the threshing frame. The mounting holes of the two types of scrap augers are consistent in the horizontal direction, and the vertical mounting holes are reserved in the threshing frame according to the required length. The mounting hole of the baffle 5 is reserved on the scrap nozzle in the threshing frame. There is no need to disassemble or replace the entire threshing machine. The adjustment of the threshing machine structure is reversible, and the threshing machine structure can also be replaced from the scrap return drum to the scrap return screen.
