Description

Technical Field

[0001] The present application relates to the field of harvesters, and particularly to a detection device for a harvesting knife of a harvester. Background Art

[0002] The detection device uses a detection rope. The detection rope is clamped so that the detection rope is cut off by passing through the harvesting knife, thereby achieving the purpose of detecting the sharpness of the harvesting knife. A harvester is a machine that integrally harvests crops, completing harvesting, threshing at one time, and concentrating the grains in a storage bin, and then transporting the grains to a transport vehicle through a conveyor belt. If the cutting knife becomes dull during harvesting, it will lead to a decrease in harvesting efficiency and even damage to the cutting knife. Generally, it is difficult to find whether the cutting knife is sharp when the harvester has not yet worked. If the cutting knife is replaced after work, the harvesting speed will be greatly reduced and a large amount of time will be wasted.

[0003] The patent document with the publication number CN112881225B discloses a detection device for a harvesting knife of a harvester, including a frame, a positioning component, and a moving detection component; belonging to the technical field related to the detection of harvesting knives of harvesters, the first positioning seat and the second positioning seat support the harvesting knife, the first horizontal positioning plate and the second horizontal positioning plate have a positioning and clamping effect on the harvesting knife, the positioning pressing plate is slidably connected to the positioning pressing plate connecting seat, there is a pressing column on the positioning pressing plate, and the pressing column has a pressing effect on the harvesting knife. A cosine track frame is also fixedly connected to the base, and the cosine contact roller contacts the cosine track frame to make the telescopic frame perform telescopic movement. A detection rope clamping device is arranged on the detection rope clamping and transposition frame, the detection rope is straightened and clamped by the clamping device, and the detection rope is cut off when passing through the cutting edge of the harvesting knife, so as to detect the sharpness of the cutting edge. The structure of the present invention is novel, and it can complete the sharpness detection of the cutting edge of the harvesting knife, and the detection efficiency is high.

[0004] However, in the prior art of the above-mentioned detection device for a harvesting knife of a harvester, there are disadvantages that the harvesting knife cannot be polished after the detection of the harvesting knife, resulting in a decrease in harvesting efficiency, and the harvesting knife cannot be cleaned, resulting in the harvesting knife being easily covered with soil and reducing the harvesting efficiency. For this reason, we propose a detection device for a harvesting knife of a harvester to solve the above problems. Utility Model Content

[0056] The implementation principle of a harvester cutting tool detection device according to an embodiment of the present application is as follows: First, both ends of the detection rope are respectively fixed on two fixed shafts 36. By moving two sliders 35 to the cutting tool 39, the cutting tool 39 is started to cut the detection rope to test the sharpness of the cutting tool 39. During the harvesting process, the cutting tool 39 cannot be replaced, so the cutting tool 39 is polished to improve the harvesting efficiency. After the rapid harvesting is completed, the cutting tool 39 can be replaced. The push rod motor 4 is started, and the push rod motor 4 drives the second box body 5 to move. The second box body 5 drives the first motor 6 to move. The second box body 5 drives the sliding plate 9 to move. The sliding plate 9 drives a plurality of first transmission shafts 10 to move.

The threaded sleeve 8 drives the sliding plate 9 to move. The sliding plate 9 drives a plurality of first transmission shafts 10 to move. The sliding plate 9 drives two second transmission shafts 14 to move. The first transmission shaft 10 drives the first gear 16 to move, so that the first gear 16 meshes with the second gear 17. Subsequently, the second motor 19 is started, and the second motor 19 drives the third transmission shaft 18 to rotate. The third transmission shaft 18 drives the second gear 17 to rotate. The second gear 17 drives the first gear 16 to rotate. The first gear 16 drives the second transmission shaft 14 to rotate. The second transmission shaft 14 drives the second sprocket 15 to rotate. The second sprocket 15 drives a plurality of first sprockets 11 and another second sprocket 15 to rotate through the chain 12. A plurality of first transmission shafts 10 drive the grinding plate 13 to rotate, so that the grinding plate 13 polishes the cutting tool 39, so that the cutting tool 39 will not cause the harvesting efficiency to decrease due to the decrease in sharpness. At the same time, the two second transmission shafts 14 respectively drive two first bevel gears, and the two first bevel gears respectively drive two second bevel gears 21 to rotate. The two second bevel gears 21 respectively drive two fourth transmission shafts 22 to rotate. The two fourth transmission shafts 22 respectively drive two rotating plates 23 to rotate.

[0057] Embodiment 2

[0058] The difference between this embodiment and Embodiment 1 is that: a tensile force tester is fixedly connected to the top of the slider 35. When the harvesting knife 39 cuts the detection rope, one end of the detection rope is fixed on the tensile force tester. When cutting, the detection rope is horizontally stressed, and the sharpness of the harvesting knife 39 can be accurately and clearly determined through the numerical display of the tensile force tester.
