[0003] In the process of mechanical harvesting, due to the unevenness of the terrain in the field in different regions, the header will shake with the whole vehicle during harvesting due to the terrain difference, so that the header spring teeth cannot collect the lower peppers into the header, resulting in a high loss rate of pepper harvesting. To solve this problem, the inventor has proposed a header that has profiling function, which lowers to the ground roller during harvesting, and when the ground is uneven, the header ground roller swings left and right due to its own weight, realizing left and right floating function, ensuring the net rate of crops within the working width of the header, and the header can float with the terrain difference, solving the problem of high loss caused by terrain problems;

[0004] However, due to the close-to-ground harvesting of the profiling picking header, weeds and other winding objects are easily wound around the shafts on both sides of the header roller during high-speed rotation, which requires frequent downtime for cleaning and maintenance, resulting in wasted time and increased costs. SUMMARY

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented without one or more of these details.

[0027] ​Embodiment 1: refer to Figures 1-2 The embodiment is a non-row low-loss profiling anti-winding picking header, which comprises a header body 10, a rotating shaft 11 installed inside the header body 10, in order to ensure a low loss rate, the floating header almost approaches the ground to carry out harvesting work, under the driving of power, the rotating shaft 11 rotates, the rotating shaft 11 drives the header body 10 to rotate, and the header body 10 is provided with elastic teeth 13 on the surface, the elastic teeth 13 are made of elastic material, the elastic teeth 13 rotate when the header body 10 rotates, and the elastic teeth 13 pick the peppers on the plants, in the embodiment, nylon elastic teeth are adopted, which can well reduce the damage of the peppers during harvesting; at the same time, the picking header is a non-row header, which is suitable for picking peppers with different row spacing. The header body 10 is fixedly installed with an inclined table plate 14, one side of the inclined table plate 14 is provided with a mounting plate 15, one side of the mounting plate 15 is provided with a separation and accommodation groove 16, the surface of the rotating shaft 11 is provided with an assembly frame 17, screw grooves are correspondingly provided on the assembly frame 17 and the mounting plate 15, and the assembly frame 17 and the mounting plate 15 are fixedly installed by screwing screws into the screw grooves; when it is necessary to disassemble the rotating shaft 11, the screws are first disassembled from the screw grooves, then the assembly frame 17 is rotated, the protruding part of the assembly frame 17 is overlapped with the separation and accommodation groove 16, and the rotating shaft 11 is pulled to complete the separation from the header body 10;

[0028] Refer to Figure 2 A rotating assembly 20 is arranged at the connection between the header body side plate 12 and the rotating shaft 11, the rotating assembly 20 comprises a bearing 21 installed at the end of the rotating shaft 11, a bearing groove 22 is arranged on the side of the header body side plate 12 away from the header body 10, a mounting cover 23 is fixedly installed on one side of the header body side plate 12, the mounting cover 23 and the header body side plate 12 are provided with a thread groove matched with each other, the mounting cover 23 is fixedly installed with the header body side plate 12 by screwing screws into the inside of the thread groove, a region for installing the bearing 21 is formed between the mounting cover 23 and the header body side plate 12, the bearing 21 is installed in the mounting cover 23 to reduce the aggravation of the wear of the bearing 21 caused by the external environment, and the bearing 21 is shielded to avoid the winding of the winding object around the bearing 21;

[0029] Refer to Figure 4 Both ends of the header body 10 are provided with a cleaning area 30, the winding objects such as weeds on both sides of the peppers enter into the cleaning area 30 during harvesting, a width disc 31 is installed at the end of the header body 10, and a cavity between the header body side plate 12 and the width disc 31 forms the cleaning area 30;

[0030] Refer to Figures 1-2The inside of the cleaning area 30 is provided with a cleaning assembly 40 which cleans the entanglement to avoid the entanglement winding the rotating shaft 11. The cleaning assembly 40 comprises a grass cutting knife 41 which is rotatably arranged in the inside of the cleaning area 30. The grass cutting knife 41 is made of steel plate and has good wear resistance and long service life during operation. The grass cutting knife 41 is fixedly installed on one side of the width disc 31. The width disc 31 is uniformly provided with three groups of grass cutting knives 41 which are arranged at an angle of 30°-65° with the center line of the width disc 31. When the impurities are mixed in the gap between the width disc 31 and the header body 10, the grass cutting knife 41 which rotates with the width disc 31 can effectively remove the impurities. The grass cutting knife 41 first contacts the entanglement during rotation and cuts some relatively weak entanglements such as weeds. The grass cutting knife 41 cuts off the relatively long and easily broken impurities. The impurities which are not easily broken are laid down by the grass cutting knife 41, so that the height of the entanglement is reduced and the entanglement is difficult to enter the cleaning area 30 to avoid winding. The grass cutting knife removes most of the impurities by centrifugal force during rotation.

[0031] The arc baffle disc assembly 50 is fixedly installed on one side of the cleaning area 30 of the header body side plate 12. The arc baffle disc assembly 50 comprises a baffle disc 51 which is installed on the header body side plate 12. The baffle disc 51 is provided with a threaded groove which is matched with the installation cover 23 and the header body side plate 12. The installation cover 23 is fixedly installed on the header body side plate 12 by screws, and the baffle disc 51 is also fixedly installed on the header body side plate 12. The arc baffle disc assembly 50 further comprises a protective cover 52 which is sleeved on the surface of the rotating shaft 11. The protective cover 52 covers the outside of the rotating shaft 11 in the cleaning area. One side of the protective cover 52 is fixedly installed on the baffle disc 51. The arc baffle disc assembly 50 further comprises a baffle ring 53 which is installed on the surface of the protective cover 52. The baffle ring 53 shields the inclined platform 14 and avoids the entanglement entering the inside of the header body 10. The baffle ring 53 can effectively block the weeds and other entanglements from winding the rotating shaft of the header body 10 and prevent the rotating shaft from being damaged.

[0032] Advantages:

[0033] 1. The header body 10 is driven to rotate by external power. The rotating shaft 11 drives the header body 10 to rotate, so that the spring teeth 13 harvest the peppers. At this time, the weeds and other entanglements beside the peppers enter the cleaning area 30. The cleaning assembly 40 cleans the entanglement to avoid the entanglement winding the rotating shaft 11. At the same time, the arc baffle disc assembly 50 has simple structure and convenient assembly, can effectively block the weeds and other entanglements from winding the rotating shaft of the header body 10, and prevent the rotating shaft from being damaged. The device combines and matches the two ways of blocking and removing to prevent the entanglement of impurities. On the premise of ensuring low loss, the problem of impurities winding the header body 10 is solved, the time for stopping and cleaning and maintaining is reduced, the work efficiency is improved, the labor cost is reduced, and the device has good popularization prospect.

[0034] 2、When the header body 10 rotates, it drives the reel 31 to rotate, and the reel 31 drives the grass cleaning knife 41 to rotate. When the grass cleaning knife 41 rotates, it uses the rotary force away from the rotating shaft 11 to cut some relatively fragile weeds and other winding objects. The relatively long and easily broken impurities will be cut off, and the impurities that are not easily broken will be laid flat under the driving of the grass cleaning knife 41, so that the height of the winding object is reduced and it is more difficult to wind. Under the action of rotation, the centrifugal force of the grass cleaning knife drives the airflow to discharge most of the impurities along the rotation direction. Finally, when a small number of impurities continue to wind the drum, the circular arc baffle assembly 50 can effectively block the impurities outside the circular arc baffle, so that the impurities cannot wind the header rotating shaft, and the rotating shaft 11 is protected.

[0035] When the grass cleaning knife 41 cuts some relatively tough winding objects, it may not be able to be cut off due to insufficient rotary force. In order to ensure that the peppers are not damaged during picking, the header body 10 cannot increase the force when the grass cleaning knife 41 contacts the winding object by increasing the rotating speed. The rotation of the grass cleaning knife 41 alone is difficult to complete the cutting of some relatively tough winding objects, and its application scene has certain limitations. Therefore, we propose embodiment 2:

[0036] Embodiment 2 is a further improvement based on embodiment 1. Referring to Figures 3-4 , the embodiment is a low-loss profiling anti-winding harvesting header that does not wind. The cleaning assembly 40 includes a main knife body 42 installed on one side of the reel 31. One end of the main knife body 42 is provided with a rotary cutting arc plate 43. The cutting part of the main knife body 42 is bent to form the rotary cutting arc plate 43. The rotary cutting arc plate 43 is coaxial with the rotating shaft 11. One end of the inclined surface of the rotary cutting arc plate 43 is close to the reel 31, and the other end of the inclined surface of the rotary cutting arc plate 43 is close to the header body side plate 12. One side of the rotary cutting arc plate 43 is provided with a transverse cutting part 44 connected with the inclined surface. One side of the transverse cutting part 44 is polished with the arc edge of the rotary cutting arc plate 43 to form a knife edge. The header body side plate 12 is fixedly installed with a fixed knife 45 on one side. When the main knife body 42 rotates, the winding object is pushed to one side of the fixed knife 45. At the same time, the winding object is broken or pushed away from the reel 31 side through the inclined surface of the rotary cutting arc plate 43. The winding object is cut off by the shearing of the transverse cutting part 44 and the fixed knife 45. The broken and cut-off mode can save more labor than direct cutting, reduce the jerking feeling caused by direct cutting, and has better cutting effect.

[0037] Beneficial effects: By setting the main knife body 42, compared with the rotary cutting mode of the grass cleaning knife 41, the shearing of the transverse cutting part 44 and the fixed knife 45 can easily deal with relatively tough winding objects, making the cutting more complete and reducing residues, and further improving the anti-winding effect of the device.

[0038] Embodiment 3: Embodiment 3 is a further improvement based on embodiment 2. Referring to Figure 5The cutting surface of the transverse cutting part 44 is an arc-shaped cutting surface with protruding ends and a concave middle section.

[0039] Beneficial effect: When cutting, the transverse cutting part 44 exerts force on the fixed knife 45 under rotation, and the entanglement first enters the arc-shaped cutting area. At this time, the protruding ends coincide with the fixed knife 45 before the middle section, and the entanglement is fixed in the arc-shaped area, avoiding accidental entry of the entanglement into the area between the main knife body 42 and the side plate 12 of the cutting table body 12 during cutting, avoiding accumulation that hinders the rotation of the main knife body 42, and further avoiding device downtime for cleaning.

[0040] Embodiment 4: Embodiment 4 is a further improvement based on Embodiment 3, referring to Figure 6 The included angle between the main knife body 42 and the rotary cutting arc plate 43 is an acute angle.

[0041] Beneficial effect: The acute angle of the main knife body 42 is inclined forward near the center of the cutting table body 10 and inclined backward away from the center of the cutting table body 10, so that the entanglement can directly separate from the cleaning area 30 after cutting, and the centrifugal force during the rotation of the main knife body 42 can complete the separation. Compared with the way of inclining backward near the center of the cutting table body 10, the entanglement after cutting is prevented from falling on the main knife body 42 and rotating with the main knife body 42 in the cleaning area 30 at a lower speed, reducing the probability of secondary entanglement after cutting, and enabling the cutting table body to operate at a lower speed, suitable for different scenarios.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Other modifications or equivalent replacements to the technical solutions of the present application made by those skilled in the art should be covered within the scope of the claims of the present application, as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
