Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production devices, in particular to a double-side driven combined auger. Background Art

[0002] A corn harvester is a type of agricultural machinery specifically designed for harvesting corn. It efficiently completes the entire corn harvesting process, from ear removal to threshing, separation, and collection. The harvester's header is a key component, responsible for removing mature corn ears and performing preliminary processing, laying the foundation for subsequent threshing and separation.

[0003] The existing corn ear picking platform mainly includes a corn ear picking device at the front end and a feeding auger at the rear end. The corn ear picking device at the front end is now divided into a single-row cutting platform and a multi-row cutting platform. Among them, the single-row cutting platform is smaller in size and is suitable for small-scale or specific row spacing corn fields; the multi-row cutting platform is used for large-scale planting and can process multiple rows of corn at one time, significantly improving work efficiency. Therefore, it is more widely used in actual applications; and the corresponding multi-row cutting platform must be equipped with a longer feeding auger to work with it.

[0004] In the prior art, a single feed auger with a single drive from one side is typically used for multi-row corn headers with more than 12 rows. However, due to the long radial length of the single feed auger, it is prone to bending during operation, resulting in a relatively weak bending resistance of the auger. In addition, its coaxiality cannot be effectively guaranteed. Utility Model Content

[0034] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0035] like Figure 1 、 Figure 2 As shown, this embodiment provides an anti-wear crop divider, comprising: a left auger assembly 100, a left drive sprocket 200, a first connecting assembly 300, a right auger assembly 400, a right drive sprocket 500 and a second connecting assembly 600;

[0036] One end of the left auger assembly 100 is connected to the left drive sprocket 200, and one end of the right auger assembly 400 is connected to the right drive sprocket 500. When facing multiple rows of corn cutting platforms, two combined auger assemblies are used and driven from both sides, which improves the auger's bending resistance and effectively resists the bending stress that may be encountered during operation, reducing operation interruptions caused by auger bending. In addition, it also reduces the manufacturing difficulty of a single auger that is too long.

[0037] The other end of the left auger assembly 100 is designed with a first groove, into which the first connecting assembly 300 is embedded. The other end of the right auger assembly 400 has a second groove, also rectangular, which houses the second connecting assembly 600. These two connecting assemblies, one concave and one convex, are connected by a taper fit, which not only ensures a tight connection between the left auger assembly 100 and the right auger assembly 400, but also increases the overall length of the auger, meeting production requirements.

[0038] The tapered connection improves the coaxiality of the auger assembly, maintaining the stability and precision of the auger during operation. In addition, this connection method can prevent entanglement or winding into the internal parts, avoiding bearing winding, further improving the reliability and durability of the auger assembly.

[0039] In this embodiment of the present invention, the left auger assembly 100 includes a left auger roller 101, within which a first transmission shaft 102 is inserted. The first transmission shaft 102 rotatably engages with the left auger roller 101 and is connected to a left drive sprocket 200. When the left drive sprocket 200 is driven to rotate, it also drives the first transmission shaft 102 to rotate. When the first transmission shaft 102 rotates, it can drive the left auger roller 101 to rotate. A left blade 103 is connected to the surface of the left auger roller 101, which can be used to propel crop materials.

[0040] The right auger assembly 400 has the same structure as the left auger assembly 100. The right auger assembly 400 includes a right auger roller 401. A second transmission shaft 402 is inserted into the right auger roller 401. The second transmission shaft 402 and the right auger roller 401 form a rotatable fit. The second transmission shaft 402 is connected to the right drive sprocket 500. When the right drive sprocket 500 is driven to rotate, it also drives the second transmission shaft 402 to rotate. When the second transmission shaft 402 rotates, it can drive the right auger roller 401 to rotate. A right blade 403 is connected to the surface of the right auger roller 401, which can be used to propel crop materials.

[0041] In the embodiment of the present utility model, Figure 3 As shown, the first connecting assembly 300 includes a first connecting block 301 that is sleeved on the first transmission shaft 102. A circular hole is provided at the center of the first connecting block 301 and passes through the first transmission shaft 102. The first connecting block 301 is installed in the first groove. A first flange bearing 302 is also sleeved on the first transmission shaft 102. The first flange bearing 302 is fixed to the left auger roller body 101 by bolts. The first flange bearing 302 is also sleeved on the first transmission shaft 102 to support and transmit the load of the first transmission shaft 102 to ensure normal operation. The surface of the first connecting block 301 on the side away from the first flange bearing 302 is tapered and matches the second connecting block 601.

[0042] The second connecting assembly 600 includes a second connecting block 601 sleeved on the second transmission shaft 402. A circular hole is provided at the center of the second connecting block 601 and passes through the second transmission shaft 402. The second connecting block 601 is installed in the second groove. The surface of the second connecting block 601 away from the second groove is in the shape of a conical protrusion, which is used to perform a taper fit with the first connecting block 301. A second flange bearing 602 is also sleeved on the second transmission shaft 402. The second flange bearing 602 also passes through the second transmission shaft 402 and is fixed to the right auger roller body 401 by bolts; the surface of the second connecting block 601 away from the second flange bearing 602 is in the shape of a cone.

[0043] The first connecting block 301 and the second connecting block 601 are matched with each other through the tapered hole and the tapered surface.

[0044] A first support plate 700 is welded to the outer periphery of the left auger roller body 101, and a second support plate 800 is welded to the outer periphery of the right auger roller body 401. The first support plate 700 and the second support plate 800 are both used to connect the cutting platform bracket. Concentric holes are opened on the first support plate 700 and the second support plate 800, and are connected by two bolts.

[0045] The first connecting component 300 is connected to the second connecting component in a tapered manner, so that the left auger component 100 is connected to the right auger component 400; while increasing the length of the auger, it meets the production requirements. The tapered connection can not only improve its coaxiality, but also effectively prevent the internal direct connection shaft from causing bearing entanglement.

[0046] In this embodiment of the present invention, the connections between the first transmission shaft 102 and the left drive sprocket 200, and between the second transmission shaft 402 and the right drive sprocket 500, are both spline or keyway connections. These connections provide high torque transmission while ensuring reliable and stable connections. These spline or keyway connections allow for precise synchronization between the transmission shafts and the drive gears, maintaining auger operation even under high loads or high speeds.

[0047] The left blade 103 and the right blade 403 are both spiral or arc-shaped. This improves the fluidity and conveying efficiency of the material in the auger assembly. When spiral blades are used, the material can be effectively pushed along the axis.

[0048] Arc plate-shaped blades help to smoothly transition the material, reduce blockage and accumulation of materials during transportation, and thus improve overall operating efficiency.

[0049] The material thickness of the outer edge line of the left blade 103 and the right blade 403 is greater than the material thickness of the inner edge line. This is because friction occurs between the conveyed material and the blades, causing the blades to wear. The wear amount of the outer edge line part with the largest linear velocity is much greater than the material wear amount of the inner edge line part, which can increase the wear resistance of the blades and extend their service life.

[0050] The outer surfaces of the left blade 103 and the right blade 403 are both covered with a corrosion-resistant layer, which not only protects the blades from erosion by moisture, dirt and chemicals, but also extends the service life of the blades and reduces maintenance costs and frequency.

[0051] The ends of the first transmission shaft 102 and the second transmission shaft 402 are both provided with sealing assemblies, which can effectively prevent dust, moisture and other impurities from entering.

[0052] Four evenly distributed through holes are evenly opened on the surface of the left drive sprocket 200 and the right drive sprocket 500, which helps to improve the heat dissipation performance of the gears, reduce the weight of the gears, and improve the dynamic balance of the overall auger device.

[0053] Based on the above embodiment, the working process of a double-side driven combined auger provided by the embodiment of the utility model is as follows:

[0054] When starting work, the left drive sprocket 200 and the right drive sprocket 500 are connected and drive the auger assembly on the left and right sides respectively. When the drive gears rotate, their power is transmitted to the auger roller body through the transmission shaft, so that the left auger assembly 100 and the right auger assembly 400 start to rotate.

[0055] The first connecting assembly 300 and the second connecting assembly 600 are connected by a taper fit, which ensures the tight connection and coaxiality of the left auger assembly 100 and the right auger assembly 400, increases the length of the auger, and maintains the auger's anti-bending performance during operation.

[0056] As the auger assembly rotates, the left blade 103 and the right blade 403 begin to push the crop material and transport it forward through the interior of the auger assembly, completing the preliminary processing work of plucking and threshing the crop.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
