Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a lifter device of a harvester. Background Art
[0002] In China, the harvesting cycles of wheat and corn are getting shorter and shorter. If a harvester is not equipped with a lifter, the grains or ears separated from the crops may directly accumulate at a certain part of the harvester, such as the outlet of the auger blade. This kind of accumulation will cause the materials to be unable to be transported and processed in time, thus affecting the continuous operation ability of the harvester; due to the accumulation of materials, the harvester may need to stop frequently for cleaning, which not only increases the labor intensity of the operators, but also greatly reduces the operation efficiency; during the accumulation process, the materials may be mixed with impurities, such as soil, miscellaneous leaves, etc., increasing the difficulty of subsequent cleaning and processing, and may also reduce the quality of the materials; the accumulation of materials may cause some components of the harvester (such as augers, transmission components, etc.) to bear excessive loads, thus accelerating wear and damage. Long-term high-load operation and material accumulation may lead to various failures of the harvester, such as blockage, jamming, etc., affecting the stability and service life of the equipment.
[0003] And as Figure 1 shown, the partition plate 001 of the existing harvester lifter is integral, with serious backhaul and frequent blockage, resulting in serious deformation at the lower part of the partition plate and great difficulty in repair, affecting the stability of the machine, increasing the later maintenance cost, and affecting the income of machine maintenance users.

Detailed Embodiments
[0024] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
[0025] Such as Figure 2As shown in the figure, a lift device of a harvester includes a housing 1, an intermediate partition 2, a conveying component 3 and a transmission component 4. The conveying component 3 includes an auger blade 31 and a conveying shaft 32. The transmission component 4 includes a driving sprocket 41, a driven sprocket 42 and a chain 43. One end of the conveying shaft 32 is arranged at one end inside the housing 1. The auger blade 31 is arranged on the conveying shaft 32 located outside the housing 1. The driving sprocket 41 is arranged on the conveying shaft 32. The driven sprocket 42 is arranged at the other end inside the housing 1. The chain 43 is annularly sleeved on the driving sprocket 41 and the driven sprocket 42. The intermediate partition 2 passes through the annular chain 43 and is connected to both sides of the housing 1.
[0026] The housing 1 of the lift is a cuboid box with a hollow interior, covering the intermediate partition 2 and the transmission component 4. Part of the conveying component 3 is placed inside the housing 1 and part is located outside the housing 1. The end of the conveying shaft 32 is located inside the housing 1. On one side of the housing 1 through which the conveying shaft 32 passes, there is an input port with a diameter equal to or larger than the diameter of the auger blade 31 after rotation. The auger blade 31 is arranged on the conveying shaft 32 and is located outside the housing 1. The rotation of the conveying shaft 32 drives the auger blade 31 to rotate, and the annular auger blade 31 feeds the material into the housing 1 through the input port.
[0027] The transmission component 4 further includes a conveying scraper 44, and a plurality of the conveying scrapers 44 are arranged on the outer ring of the chain 43 at a set spacing.
[0028] The purpose of arranging the conveying scraper 44 is to transport the material transported into the bottom inside the housing 1 to the top of the intermediate partition 2 through the conveying scraper 44 and push the material to the next working position through the conveying scraper 44.
[0029] Such as Figure 3As shown in the figure, the conveyed material enters the bottom of the housing 1. Since the rotation of the rotating shaft drives the rotation of the driving sprocket 41, and since the driving sprocket 41 meshes with the chain 43, the chain 43 will be driven to move in a circular motion. Since the chain 43 meshes with the driven sprocket 42, the moving chain 43 will drive the driven sprocket 42 to rotate. During the movement of the chain 43, a number of conveying scrapers 44 connected thereto will be driven to move. There is a certain gap between the conveying scraper 44 and the inner wall of the elevator housing 1, ensuring that there is no friction with the housing 1, and at the same time, the material transported by the auger blade 31 can be transported above the intermediate partition 2. Specifically, the material sinking to the bottom of the housing 1 is pushed by the conveying scraper 44 running to the bottom, and rotates forward with the conveying scraper 44 from the bottom to be pushed above the intermediate partition 2. Finally, the material is placed above the intermediate partition 2, and as the conveying scraper 44 advances, the material is pushed into the next working position. The conveying shaft 32 rotates continuously to drive the auger blade 31 to continuously transport the material into the lower end of the housing 1. The spaced-apart conveying scrapers 44 continuously drive the material to run above the intermediate partition 2 and transport the material to the next working position.
[0030] The conveying scrapers 44 are arranged on the chain 43 at a set spacing, and the setting of the spacing is based on the type of material. Some materials are smaller and require denser conveying scrapers 44; when the materials are larger, the spacing of the conveying scrapers 44 can be adjusted larger.
[0031] When the conveying shaft 32 of the conveying component 3 starts to work, the auger blade 31 starts to convey the material, and the driving sprocket 41 starts to rotate to drive the chain 43 and the conveying scrapers 44 to start working, and the functions of conveying and transporting the material can be realized simultaneously, without causing material accumulation.
[0032] As Figure 4 shown in the figure, the auger blade 31 conveys continuously and stably, while the conveying scraper 44 conveys intermittently and in an impact manner. Such a time interval causes a problem of material accumulation at the bottom of the housing 1; when the conveying scraper 44 grabs and conveys the material, the impact is large and the time is short, resulting in the bottom of the original integral intermediate partition 2 being easily deformed and turned up due to material accumulation, not only unable to perform the function of the return belt but also causing interference to the rotating components and poor operation.
[0033] Therefore, the intermediate partition 2 of the present application includes a first fixing ring 21, a second fixing ring 22 and a tail partition 23. The first fixing ring 21 and the second fixing ring 22 are respectively located on both sides of the driving sprocket 41 and sleeved on the conveying shaft 32, and the tail partition 23 is fixedly connected to the first fixing ring 21 and the second fixing ring 22.
[0034] The intermediate partition 2 further includes a first anti-wear sleeve 24 and a second anti-wear sleeve 25. The first anti-wear sleeve 24 is arranged between the first fixing ring 21 and the conveying shaft 32, and the second anti-wear sleeve 25 is arranged between the second fixing ring 22 and the conveying shaft 32.
[0035] The intermediate partition 2 further includes a first reinforcing rib 26 and a second reinforcing rib 27. The first reinforcing rib 26 and the second reinforcing rib 27 are arranged at the bottom of the tail partition 23. The end of the first reinforcing rib 26 is connected to the first fixing ring 21, and the end of the second reinforcing rib 27 is connected to the second fixing ring 22.
[0036] The intermediate partition 2 is detachably connected to both sides of the housing 1 through the annular chain 43.
[0037] Grooves are arranged on both side edges inside the housing 1, and the intermediate partition 2 is arranged on the grooves inside the housing 1.
[0038] Both the first anti-wear sleeve 24 and the second anti-wear sleeve 25 are made of nylon.
[0039] The first reinforcing rib 26 and the second reinforcing rib 27 are welded to the bottom of the tail partition 23. The end of the first reinforcing rib 26 is welded to the first fixing ring 21, and the end of the second reinforcing rib 27 is welded to the second fixing ring 22.
[0040] The tail partition 23 is welded to the first fixing ring 21 and the second fixing ring 22.
[0041] The first fixing ring 21, the second fixing ring 22 of the intermediate partition 2 and the tail partition 23 are welded together to ensure no hard friction with the conveying shaft 32. The first anti-wear sleeve 24 and the second anti-wear sleeve 25 made of nylon are installed in the middle; the first reinforcing rib 26 and the second reinforcing rib 27 are added at the bottom of the tail partition 23 to ensure the overall strength. When the impact of the conveying scraper transporting materials is too large, the force can be transmitted to the conveying shaft 32 through the first fixing ring 21 and the second fixing ring 22, and the conveying shaft 32 transmits the force to the bearings on both sides; due to the elastic deformation of the device, the first anti-wear sleeve 24 and the second anti-wear sleeve 25 in the middle are in soft contact with the conveying shaft 32 to ensure that the whole is not deformed by strong impact.
[0042] The intermediate partition 2 is an integral welded part, and the first anti-wear sleeve 24 and the second anti-wear sleeve 25 made of nylon are assembled parts. When the first anti-wear sleeve 24 and the second anti-wear sleeve 25 are severely worn, they can be quickly replaced; when there is a problem with the integral welded part, the intermediate partition 2 can also be disassembled as a whole for replacement or repair.
[0043] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
