Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a double grain bin structure for a harvester and a corn harvester. Background Technology

[0002] In plains areas, cornfields are large and have long edges, resulting in a longer harvesting distance for corn harvesters in a single pass. This places higher demands on the size of the corn harvester's ear box and kernel collection bin. The ear box is used to collect the hulled corn ears, while the kernel collection bin is used to collect the corn kernels that fall off the ears during the hulling process.

[0003] Currently, most grain collection bins are designed below the peeling device, resulting in a very limited volume. In situations with long harvest periods and long field lengths, the small bin volume causes it to fill quickly, leading to grain spillage and waste, impacting harvesting efficiency. Furthermore, the bin's tendency to fill rapidly increases cleaning frequency, further reducing efficiency. Additionally, overflowing grains can clog the mechanism, affecting the harvester's reliability. Utility Model Content

Detailed Implementation

[0028] To enable those skilled in the art to better understand this utility model, the present utility model will be further described clearly and completely below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] This utility model provides a typical embodiment of a harvester with a double grain bin structure, such as... Figure 1As shown, it includes a first grain collecting mechanism 2, a ear collecting mechanism 3, a second grain collecting mechanism 4, and a conveying mechanism 5.

[0030] The first grain collecting mechanism 2, the ear collecting mechanism 3, the second grain collecting mechanism 4, and the conveying mechanism 5 are all directly or indirectly installed on the frame 1 to achieve overall movement.

[0031] The grain silo structure is designed to work in conjunction with a peeling mechanism (not shown in the figure), which is located directly above the first grain collection mechanism 2. The peeling mechanism can utilize existing related structures. The peeling mechanism peels the corn husks to produce ears, which are then collected by the grain silo structure.

[0032] The first kernel collecting mechanism 2 is located below the peeling mechanism of the harvester and is used to collect kernels falling from the bottom of the peeling mechanism. The ear collecting mechanism 3 is located on one side of the peeling mechanism and is used to carry the corn ears output by the peeling mechanism.

[0033] For example, the first grain collection mechanism 2 includes a funnel-shaped grain recovery bin and an auger structure, through which grains in the grain recovery bin are output to the conveying mechanism 5. The auger structure can be of a suitable type as needed.

[0034] Because the hulling mechanism causes some damage to the corn ears during hulling, resulting in the kernels falling off, the first kernel collection mechanism 2 is located below the hulling mechanism to facilitate the collection of the fallen kernels. However, while this location facilitates kernel collection, it also limits the volume of the first kernel collection mechanism 2, making it relatively small. Therefore, the grain silo structure includes a second kernel collection mechanism 4.

[0035] The second grain collecting mechanism 4 is located on the side of the ear collecting mechanism 3 away from the first grain collecting mechanism 2. The volume of the second grain collecting mechanism 4 is larger than that of the first grain collecting mechanism 2, so as to increase the grain capacity and reduce the cleaning frequency.

[0036] One end of the conveying mechanism 5 is connected to the first grain collecting mechanism 2, and the other end is located above the second grain collecting mechanism 4. The conveying mechanism 5 is used to transport the grains in the first grain collecting mechanism 2 to the second grain collecting mechanism 4. By connecting the first grain collecting mechanism 2 and the second grain collecting mechanism 4 through the conveying mechanism 5, the grains can be collected in the second grain collecting mechanism 4, which has a larger volume. This prevents the grains from overflowing and avoids frequent cleaning, thereby improving the harvesting efficiency of corn and reducing the labor intensity of the operators.

[0037] As a preferred embodiment, such as Figure 3As shown, the ear collection mechanism 3 includes an ear collection box 32, an ear support frame 33, and an ear collection box drive 34; the lower end of the ear support frame 33 is connected to the frame 1, and the upper part of one side of the ear collection box 32 is rotatably connected to the upper part of the ear support frame 33; the fixed end and the movable end of the ear collection box drive 34 are respectively hinged to the ear support frame 33 and the ear collection box 32, and are used to drive the ear collection box 32 to rotate.

[0038] After the ear collection box 32 is full, the ear collection box drive 34 drives the ear collection box 32 to rotate around the connection point with the ear support frame 33, thereby flipping the ear collection box 32 and tilting the ears in the ear collection box 32 through the tilting port at the top.

[0039] The ear collection box 32 has an ear inlet at the top of the side wall near the peeling mechanism. The corn ears output by the peeling mechanism enter the ear collection box 32 through the ear inlet.

[0040] The drive component 34 of the ear collection box can be a cylinder, hydraulic cylinder, or electric telescopic rod, etc., to achieve remote control of the action without the need for manual unloading by the operator. A rotating shaft is provided on each of the top two sides of the ear support frame 33, and a bushing is correspondingly provided on the side wall of the ear collection box 32. The rotating shafts are rotatably connected to the bushings, realizing the rotatable connection between the ear collection box 32 and the ear support frame 33.

[0041] As a preferred embodiment, such as Figure 4 As shown, the second grain collection mechanism 4 includes a grain collection box 41 and a grain support frame 42. The lower end of the grain support frame 42 is connected to the vehicle frame 1, and the upper part of one side of the grain collection box 41 is rotatably connected to the grain support frame 42.

[0042] The grain support frame 42 provides support for the grain collection box 41 to flip, so that the second grain collection mechanism 4 can flip around the connection position between the grain collection box 41 and the grain support frame 42, so as to pour out the grains carried inside.

[0043] In this embodiment, a rotating shaft is provided on each of the top two sides of the first support part 421, and a bushing is correspondingly provided on the top of the side wall of the grain collection box 41. The rotating shaft is rotatably connected to the bushing, thereby realizing the rotatable connection between the grain collection box 41 and the grain support frame 42.

[0044] In a more specific embodiment, the second grain collecting mechanism 4 further includes a grain collecting box drive component 43; the grain support frame 42 includes a first support portion 421 and two second support portions 422, the two second support portions 422 are disposed on both sides of the grain collecting box body 41, the lower end of the first support portion 421 and the lower end of the second support portion 422 are both connected to the frame 1, and the upper end of the second support portion 422 is connected to the first support portion 421.

[0045] The fixed end of the seed collection box drive 43 is hinged to the second support portion 422, and the movable end is hinged to the seed collection box body 41. The height of the movable end of the seed collection box drive 43 is higher than the height of the fixed end of the seed collection box drive 43. The seed collection box drive 43 is used to drive the seed collection box body 41 to rotate.

[0046] Preferably, both the first support portion 421 and the second support portion 422 are inclined, and the inclination angle between the first support portion 421 and the horizontal plane is greater than the inclination angle between the second support portion 422 and the horizontal plane, so that the seed collection box drive component 43 can drive the seed collection box body 41 to flip.

[0047] On one hand, the first support portion 421 and the two second support portions 422 can support and limit the grain collection box 41, allowing the grain collection box 41 to be stably placed on the frame 1. On the other hand, the extension and retraction of the grain collection box drive component 43 can drive the grain collection box 41, enabling it to flip and reset. Two grain collection box drive components 43 can be provided, symmetrically arranged on both sides of the grain collection box 41, with the fixed ends of the two drive components 43 respectively connected to the two second support portions 422. The grain support frame 42 may also include multiple auxiliary support rods, which connect between the first support portions 421 or connect the first support portions 421 and the second support portions 422 to improve support strength.

[0048] In another preferred embodiment, the second grain collecting mechanism 4 further includes a guide member 44, which has a C-shaped cross-section and includes a base plate and side plates fixed to both sides of the base plate. The first end of the guide member 44 is rotatably connected to the upper end of the grain collecting box 41. An arc-shaped groove 441 is provided through the side plate of the guide member 44, and a guide pin 411 is provided on the side wall of the grain collecting box 41, the guide pin 411 being slidably connected within the arc-shaped groove 441.

[0049] The guide member 44 is used to guide the grains during the pouring process. When the grain collection box 41 is tilted, the guide pin 411 slides relative to the guide pin 441 within the arc-shaped groove 441, which can adjust the tilt angle of the guide member 44, thereby adjusting the output distance of the grains. The output end edge of the guide member 44 is provided with a transition section, and the connection between the transition section and the guide member 44 is rounded.

[0050] The top of the ear collection box 32 is also equipped with a flow guide, the structure and function of which are similar to the flow guide on the top of the grain collection box 41.

[0051] In a preferred embodiment, such as Figure 5 As shown, the conveying mechanism 5 includes a transverse conveying section 51 and a longitudinal conveying section 52; one end of the transverse conveying section 51 is connected to the bottom end of the first grain collecting mechanism 2, and the other end of the transverse conveying section 51 is connected to the lower end of the longitudinal conveying section 52; the upper end of the longitudinal conveying section 52 extends to the top opening of the second grain collecting mechanism 4.

[0052] The transverse conveyor section 51 is horizontally mounted on the frame 1, which helps improve the stability of the conveying process and enhances the grain output efficiency within the first grain collecting mechanism 2, reducing residue. The longitudinal conveyor section 52 conveys the grains to the top opening of the second grain collecting mechanism 4. The longitudinal conveyor section 52 is located between the ear-collecting mechanism 3 and the second grain collecting mechanism 4, thus realizing the conveying process of grains from the first grain collecting mechanism 2 to the second grain collecting mechanism 4. The longitudinal conveyor section 52 can be inclined at a certain angle to facilitate grain output into the second grain collecting mechanism 4. Both the transverse conveyor section 51 and the longitudinal conveyor section 52 can be multi-segment structures.

[0053] Both the transverse conveying section 51 and the longitudinal conveying section 52 include a conveying channel and a conveying auger, which is rotatably disposed inside the conveying channel. The conveying of grains within the conveying channel is achieved through the spiral rotation of the conveying auger.

[0054] It is understandable that the conveying mechanism 5 also includes a drive assembly, which typically includes a motor, sprockets, and chains. The motor drives the sprockets to rotate, which in turn drives the chain to move, thereby driving another sprocket connected to the conveying auger to rotate, and then the sprocket drives the conveying auger to rotate.

[0055] Optionally, such as Figure 3 As shown, the lower end of the ear-collecting mechanism 3 is provided with a clearance groove 31, through which the transverse conveying part 51 passes. The clearance groove 31 allows the transverse conveying part 51 to pass through the lower end of the ear-collecting mechanism 3, reducing the length extension and direction change of the transverse conveying part 51 caused by avoiding the ear-collecting mechanism 3, thus improving conveying convenience. Simultaneously, it avoids the impact of raising the entire ear-collecting mechanism 51 on its stability and practicality.

[0056] The conveying mechanism 5 also includes a support member 53, one end of which is hinged to the frame 1 and the other end is hinged to the longitudinal conveying part 52; the length of the support member 53 is adjustable to adjust the position of the longitudinal conveying part 52.

[0057] In a preferred embodiment, a limiting mechanism 6 is provided on the top of the grain collection box 41 near the ear collection mechanism 3. The limiting mechanism 6 includes a bottom plate 61 and side plates 62 fixed on both sides of the bottom plate 61. The bottom plate 61 is inclined inward into the grain collection box 41.

[0058] The upper end of the longitudinal conveying section 52 is placed within the limiting structure 6. The longitudinal conveying section 52 cooperates with the limiting mechanism 6, and the limiting mechanism 6 provides support for the output end of the longitudinal conveying section 52. This improves the stability of the longitudinal conveying section 52, thereby increasing the reliability of grain conveying.

[0059] The bottom plate 61 of the limiting mechanism 6 can guide the flow, so that the grains output by the longitudinal conveying section 52 fall into the center of the bottom of the second grain collecting mechanism 4, avoiding the grains from falling to the side of the second grain collecting mechanism 4 near the ear collecting mechanism 3 due to insufficient output speed or small output volume, causing the grains to accumulate off-center.

[0060] Another typical embodiment of this utility model provides a corn harvester, which includes the above-described double grain bin structure. The first grain collecting mechanism 2, the ear collecting mechanism 3, the second grain collecting mechanism 4, and the conveying mechanism 5 are all directly or indirectly mounted on the frame 1 of the corn harvester. The specific structure of the frame 1 is not limited, as long as it can achieve the load-bearing function.

[0061] The scope of protection claimed by this utility model is not limited to the specific embodiments described above. For those skilled in the art, this utility model can have various modifications and alterations. Any modifications, improvements and equivalent substitutions made within the concept and principles of this utility model should be included within the protection scope of this utility model.
