Description

Technical Field

[0001] The utility model relates to the technical field of agricultural crop harvesting header structures, in particular to a harvesting header for crops prone to falling grains which is provided with a multi-channel delivery loss reduction mechanism. Background Art

[0002] Mechanized harvesting is an indispensable part of modern agriculture. Buckwheat and quinoa, specialty crops of Inner Mongolia, have many health benefits, but they have the characteristics of low crop height and easy seed falling. In order to collect the fallen crops and seeds, multiple grain-dropping troughs are set on the cutting table, and multiple flexible paddles corresponding to the positions of the grain-dropping troughs and used in conjunction with them are set on the harvester's reel. The crops and seeds are sent to the side of the auger through the flexible paddles. However, the traditional reel can only make circular motions, so that the flexible paddles can only send part of the crops and seeds in the grain-dropping trough, and cannot completely clear the crops and seeds collected in the grain-dropping trough. As a result, the crops and seeds accumulate and fall again, causing losses. Therefore, it is necessary to further improve the cutting table structure.

[0003] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present application, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0005] To achieve the above purpose, the technical solutions provided by the present invention are as follows:

[0006] A harvesting header for crops prone to grain shedding provided with a multi-channel feeding and loss reduction mechanism, comprising a header frame and a reel mounted on the header frame;

[0007] The reel comprises a flexible paddle, a paddle connecting piece, a driven rod, a bearing, a windmill frame, an active rod, a paddle rod, a main shaft, a square fixing frame, a pulley, and a cam body;

[0008] The two cam bodies are arranged opposite to each other, and the two cam bodies are fixed to the cutting platform frame through a square fixing frame respectively; the two sides of the main shaft are respectively connected to a windmill frame by welding, and both ends of the main shaft pass through the cam bodies on the corresponding sides and are rotatably connected, wherein one end of the main shaft is connected to the pulley through a key;

Bearings are provided at both ends of the driven rod, and the bearings are embedded in the guide rails provided on the cam body. The flexible shift plate is fixed to the driven rod through a shift plate connecting piece. The guide rail of the cam body controls the movement trajectory so that the driven rod follows the curved trajectory of the guide rail of the cam body, and the bottom trajectory of the guide rail of the cam body fits the curve of the grain falling groove of the cutting platform frame, so that the flexible shift plate fits the grain falling groove to operate.

[0010] It also includes a spring tooth connecting piece and a spring tooth, and the spring tooth is fixed on the driven rod through the spring tooth connecting piece.

[0011] Wherein, the bearing is a 6205-2Z deep groove ball bearing.

[0020] Traditional reels move in a circular motion, and the flexible paddle can only reach the area where the grain trough and the reel meet. The improved reel, with its cam guide controlling its movement, allows the flexible paddle on the reel to follow the shape of the grain trough below for long-distance paddle movement.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set, and can refer to direct connection or indirect connection. Those skilled in the art can understand the specific meanings of the above terms in this patent based on specific circumstances.

[0028] This application optimizes the design of traditional harvesting headers and develops a multi-channel feed loss reduction mechanism for harvesting headers for crops prone to grain shedding. By changing the traditional circular structure of the reel and controlling its trajectory with a cam guide, the flexible feeder on the reel no longer moves in a circular motion but instead moves along the cam track. The header can then operate along the arc of the grain shedding trough, eliminating the problem of missed crop accumulation and subsequent secondary grain shedding, thereby improving the loss reduction effect.

[0029] like Figure 1-Figure 3 The figure shows an embodiment structure provided by the present utility model.

[0030] This embodiment provides a harvesting header for crops prone to grain shedding, which is provided with a multi-channel feeding and loss reduction mechanism, and includes a header frame 18 and a reel 19 mounted on the header frame 18;

[0031] The reel 19 includes a flexible paddle 2, a paddle connecting piece 4, a driven rod 5, a bearing 6, a windmill frame 7, an active rod 9, a paddle rod 10, a main shaft 11, a square fixing frame 14, a pulley 15, and a cam body 16;

[0032] The two cam bodies 16 are arranged opposite each other and are fixed to the cutting platform frame 18 via a square fixing frame 14. They do not rotate with the main shaft 11 and the windmill frame 7. The two sides of the main shaft 11 are respectively connected to a windmill frame 7 by welding, and both ends of the main shaft 11 pass through the cam bodies 16 on the corresponding side and are rotatably connected. Among them, one end of the main shaft 11 is connected to the pulley 15 via a key. The windmill frame 7 rotates with the main shaft, and the end of the windmill frame 7 support arm is connected to the active rod 9 via nylon bushing 8, allowing for movement. During operation, the low friction of nylon ensures smooth operation of the windmill frame 7 and the active rod 9.

[0033] The active rod 9 is rotatably connected to the windmill frame 7, and the driven rod 5 is connected to the active rod 9 through the shift rod 10, and the active rod 9 and the driven rod 5 are arranged alternately at intervals, and bearings 6 are provided at both ends of the driven rod 5, and the bearings 6 are embedded in the guide rails provided on the cam body 16, and the flexible shift plate 2 is fixed to the driven rod 5 through the shift plate connecting piece 4; the path trajectory is controlled by the guide rail of the cam body 16 so that the driven rod 5 follows the curved trajectory of the guide rail of the cam body 16, and the bottom trajectory of the guide rail of the cam body 16 fits the curve of the grain falling groove 12 of the cutting platform 18, so that the flexible shift plate 2 fits the grain falling groove 12 for operation.

[0034] Preferably, it further comprises a spring tooth connecting piece 1 and a spring tooth 3 , and the spring tooth 3 is fixed on the driven rod 5 through the spring tooth connecting piece 1 .

[0035] Preferably, the bearing 6 is a 6205-2Z deep groove ball bearing. The 6205-2Z deep groove ball bearing 6 reduces wear and tear, allowing the driven rod 5 to run smoothly in the guide rail of the cam body 16 .

[0036] Preferably, the active rod 9 is rotatably connected to the windmill frame 7 through a nylon bushing 8 .

[0037] Preferably, a square fixing frame bottom plate is fixedly connected to the outer side wall of the cam body 16, and eight first connecting holes are opened on the square fixing frame bottom plate, and these first connecting holes are distributed in a circle and connected to the square fixing frame 14, which can fix the cam body 16 and adjust the pitch angle of the cam body to adapt to different crops.

[0038] Preferably, eight second connection holes distributed in a circumference are opened on the side of the square fixing frame 14 that contacts the cam body 16 , and the first connection holes are connected to the second connection holes by bolts.

[0039] Preferably, three third connection holes are opened at the upper end of the square fixing frame 14, which are used in conjunction with multiple fourth connection holes on the contacting cutting frame 18. The third connection holes and the fourth connection holes are connected by bolts, and the position of the reel 19 can be adjusted according to different crops.

[0040] Preferably, the windmill frame 7 adopts a swastika structure. The dimensions of the windmill frame 7 are strictly designed according to the curved trajectory of the cam body 16 to ensure that the driven rod 5 runs smoothly in the guide rail of the cam body 16. The windmill frame 7 adopts a swastika structure, which can effectively reduce vibration during rotation and has a cushioning effect, making it suitable for field operations. It has a hollow center and support arms on the sides, which can reduce weight while ensuring strength.

[0041] Preferably, three levers 10 are welded to each active rod 9, with the welding angles determined by the curve of the cam 16 guide rail and the driven rod 5 within the guide rail. The two ends of the levers 10 are welded to the active rod 9 and the driven rod 5, respectively. The levers 10 are L-shaped, so that when the distal ends of the levers 10 extend and move along the grain drop trough 12, they generate a longitudinal force, effectively clearing the accumulated crop particles in the grain drop trough 12.

[0042] It should be noted that the cutting platform 18 includes: a seed drop trough 12, a brush 13, and an auger 17. The structure of the cutting platform 18 adopts well-known technology and will not be described in detail here. Among them, the seed drop trough 12 is used in conjunction with the flexible paddle 2. The multiple seed drop troughs 12 are arranged at intervals. Each seed drop trough 12 is provided with an inwardly inclined brush 13 on both sides. Most of the seeds that fall on the brush 13 will roll into the seed drop trough 12.

[0043] It should be noted that the spring tooth connecting piece 1 and the paddle connecting piece 4 are evenly spaced on the driven rod 5. As shown in the figure, optionally, for ease of installation, the corresponding flexible paddle 2 can also be set outside the connection between the paddle 10 and the driven rod 5.

[0044] It should be noted that the guide rail of the cam body 16 controls the trajectory so that the follower rod 5 on the reel 19 no longer follows a perfect circular trajectory but a curved trajectory according to the guide rail of the cam body 16. The bottom trajectory of the guide rail of the cam body 16 fits the curve of the grain-falling groove 12, so that the flexible paddle 2 on the follower rod 5 fits the grain-falling groove 12 for operation, effectively preventing the accumulation of crop particles; in addition, when the flexible paddle 2 moves along the guide rail of the cam body 16 to the end of the grain-falling groove 12, it can be retracted in time to avoid collision with the auger 17 and not interfere with the normal operation of other components.

[0045] The power equipment of the harvesting header rotates pulley 15 via a belt drive. Pulley 15 drives the main shaft 11 and the windmill frame 7 welded to the main shaft 11 to rotate together through a key connection. The rotation of the windmill frame 7 drives the active rod 9 to rotate. The rotation of the active rod 9 drives the driven rod 5 to move within the guide rail of the cam body 16 via the welded shift rod 10. The movement of the driven rod 5 drives the flexible shift plate 2 to complete the shifting movement on the grain drop chute 12.

[0046] Traditional reels move in a circular motion, and the flexible paddle can only reach the point where the grain trough and the reel meet. The improved reel, with its cam guide controlling its movement, allows the flexible paddle to paddle along the grain trough below for a long distance. This prevents excess crop from accumulating in the trough and falling out from under the harvester. This significantly improves the harvester's crop loss rate and avoids crop waste, offering excellent economic value.

[0047] It should be noted that the technical solutions not described in detail in this application all adopt publicly known technologies.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
