TECHNICAL FIELD

[0001] The utility model relates to the technical field of harvesting cylinder, concretely to a harvesting cylinder with a protection device. BACKGROUND

[0002] The harvesting cylinder, also commonly known as a header cylinder, is a rotating cylinder located in front of a combine harvester. It is mainly composed of a cylinder body, a cylinder shaft and blades, and the surface of the cylinder body is covered with spiral blades. The design of these blades can cut crops during rolling and send the cut crops into the cylinder body.

[0003] In order to assist in harvesting crops by using the harvesting cylinder, the mounting frame is fixed in the front part of the harvester in advance, and then the power of the harvester is transmitted to the fixed frame through the transmission shaft. At this time, the rotation of the transmission shaft will drive the fixed frame to rotate, and then the rotation of the fixed frame will drive the base to rotate, and then the rotation of the base will drive the cutting blades to rotate. At this time, the cutting blades will quickly cut the crops. Because of the rotation of the cylinder body, the cut crops will be sent into the cylinder body and transported to the subsequent processing procedure with the continuous rotation of the cylinder. However, during the use of the harvesting cylinder, the cutting blades will inevitably be damaged with the increase of the use time. However, the cutting blades are welded on the outside of the harvesting cylinder, so that when the cutting blades need to be replaced, the damaged cutting blades need to be cut off using a cutting device first, and then the intact cutting blades need to be welded on the outside of the harvesting cylinder. Only in this way can the replacement of the cutting blades be completed. This way of replacing the blades is time-consuming and laborious, and is not convenient enough, which affects the use of the harvesting cylinder. SUMMARY

A fixing strip is connected inside the limiting seat, and the bottom end of the outer wall of the fixing strip is welded to the mounting frame. A threaded pin is threadedly connected to the bottom end of the outer wall of the limiting seat. A limiting strip is welded to the side of the base closest to the cutting blade, and a limiting plate is welded to the bottom end of the outer wall of the cutting blade. A threaded rod is connected to the side of the base away from the cutting blade via a support block, and a guide seat is threadedly connected to the middle of the outer wall of the threaded rod. A fixing pin is welded to one side of the outer wall of the guide seat.

[0006] Preferably, the guide seat and the fixing pin have a "Z" shaped structure, the cutting blade has a limiting hole inside and a limiting strip extends into it, the cutting blades are evenly distributed, and the base is hexagonally distributed.

[0007] Preferably, the mounting bracket has a threaded hole in the middle of its outer wall corresponding to the threaded pin, the base has a movable cavity inside which the guide seat extends, and the limiting plate has a fixing hole inside which the fixing pin corresponds.

[0008] Preferably, a fixing seat is welded to the side of the mounting bracket away from the fixing frame, and a limiting member is connected inside the fixing seat. The limiting member has an "I" shaped structure, and the fixing seat has an "L" shaped structure.

[0024] In specific implementation, when the cutting blade 6 needs to be replaced during use of the harvesting cylinder, first, the threaded pin 403 is rotated to disengage from the fixing frame 3, and then the fixing of the limiting seat 401 is cancelled. Since the limiting seat 401 is connected to the base 5, and the base 5 is connected to the cutting blade 6, then only the base 5 needs to be moved to disengage the limiting seat 401 from the limiting strip 404, so that the damaged cutting blade 6 can be removed from the harvesting cylinder, and then removed from the harvester away from other cutting blades 6, so that when replacing the cutting blade 6, it is not disturbed by the remaining blades on the harvester, reducing the safety hazard when replacing the cutting blade 6, and when the damaged cutting blade 6 is replaced, only the base 5 needs to be moved close to the mounting frame 2 until the limiting strip 404 is inserted into the limiting seat 401, and then the threaded pin 403 is rotated to penetrate the limiting seat 401 and inserted into the mounting frame 2, so that the base 5 can be installed back to the original position;

[0025] When the base 5 is removed away from the mounting frame 2 to replace the damaged cutting blade 6, since the threaded rod 406 and the guide seat 407 are threadedly connected, then the threaded rod 406 is rotated to generate a pushing force on the guide seat 407, so that the guide seat 407 drives the fixing pin 408 to disengage from the limiting plate 405, and then the fixing of multiple cutting blades 6 can be cancelled at the same time, which facilitates the workers to replace multiple groups of cutting blades 6 at one time, and since the cutting blade 6 is connected to the limiting plate 405, then only the cutting blade 6 needs to be moved to move the limiting plate 405 out of the base 5, so that the damaged cutting blade 6 can be removed, then the intact cutting blade 6 is butted against the limiting strip 404, and then the threaded rod 406 is rotated to move the guide seat 407 towards the limiting plate 405, until the fixing pin 408 is inserted into the limiting plate 405, so that the fixing of the cutting blade 6 is completed, and then there is no need to use a cutting device to cut off the damaged cutting blade 6, and then use a welding device to weld the intact cutting blade 6 back to the original position, so that it is convenient to replace the damaged cutting blade 6;

[0026] Because the outer wall of the fixing frame 3 is welded with the fixing seat 409, the limiting piece 410 is connected with the supporting plate 411, the supporting plate 411 can be moved in advance to make the limiting piece 410 inserted into the inside of the fixing seat 409, and because the supporting plate 411 is connected with the protective plate 412, the movement of the supporting plate 411 will drive the movement of the protective plate 412, then the elastic force generated by the reset of the spring 415 makes the fixed rod 414 slide along the support seat 413 until the fixed rod 414 is inserted into the inside of the supporting plate 411, thereby limiting the supporting plate 411, so that the protective plate 412 is arranged outside the cutting blade 6, then when the cutting blade 6 harvests crops and encounters stones or hard sundries, the cutting blade 6 will hit the stones when rotating at high speed to cause the flying of the stones, at this time, the protective plate 412 blocks part of the flying stones to prevent the flying stones from hitting other components to cause damage, thereby reducing the safety hazard, so that the cutting blade can be conveniently replaced and the safety hazard is reduced when the cutting drum is used.

[0027] In summary, when the cutting drum with the protection device is used, the mounting frame 2 is first fixed at the front part of the harvester, then the power of the harvester is transmitted to the fixing frame 3 through the transmission shaft 1, at this time, the rotation of the transmission shaft 1 will drive the fixing frame 3 to rotate, then the rotation of the fixing frame 3 will drive the base 5 to rotate, then the rotation of the base 5 will drive the cutting blade 6 to rotate together, at this time, the cutting blade 6 will quickly cut the crops, because of the rotation of the drum body, the cut crops will be sent into the drum body and be transported to the subsequent processing procedure along with the continuous rotation of the drum, which is the prior art and will not be described in detail here, the auxiliary mechanism 4 facilitates workers to replace the damaged cutting blade 6, and the cutting blade 6 does not need to be interfered by the remaining blades on the harvester when being replaced; and the flying stones are blocked by the protective plate 412, thereby preventing the flying stones from hitting other components to cause damage and reducing the safety hazard, the contents not described in detail in the description belong to the prior art known by the person skilled in the art.

[0028] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
