Description

Technical Field

[0001] The utility model relates to the technical field of harvesting equipment, in particular to a crop harvesting device. Background Art

[0002] Crops are various plants cultivated in agriculture. After the crops have grown, they need to be harvested. In order to facilitate the harvesting of crops, mechanized crop harvesting devices are used.

[0003] To facilitate crop harvesting, numerous improvements have been made to crop harvesting devices in the prior art. For example, patent publication number CN219269577U discloses a crop harvester comprising an aluminum tube, one end of which is provided with a gearbox, an upper side of which is provided with a gathering arc plate, a lower side of which is provided with a fixing plate, a blade guard disposed near the gearbox, an inner side of the blade guard provided with a cushioning rubber, a fixing seat disposed on the upper side of the blade guard, a handle disposed at the end of the aluminum tube away from the blade guard, and a shoulder strap plate disposed on the aluminum tube on the side of the handle. The utility model utilizes the blade guard, fixing seat, and cushioning rubber to ensure that when the harvester is in use, dirt or stones attached to the rice paddies are repelled by the blades. The blade guard, through the cushioning rubber, can cushion the stones and dirt, thereby preventing injury to the harvester.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] The harvesting device in the above comparison is suitable for harvesting crops in places where large harvesters cannot enter. In reality, although large harvesters cannot enter remote mountainous areas, there are height differences between planting sites, most of which are terraced, but a piece of land for planting crops is still relatively flat. In the above comparison document, the entire harvesting device is carried on a shoulder strap. Since the entire harvesting device has a certain weight, it will cause the harvester to get tired quickly, increasing the labor intensity of the harvester. Therefore, there is an urgent need in this field to improve the crop harvesting device to solve the defects of the existing technology. Utility Model Content
