Description

Technical Field

[0001] The utility model relates to the technical field of water chestnut harvesting, and in particular to a hydraulically controlled water chestnut harvesting device. Background Art

[0002] Water chestnuts are a kind of fruit that grows in the soil. When the fruit is ripe, it must be dug out from the soil of the field using agricultural machinery or farm tools. Generally, water chestnuts are 15-20cm deep under the soil, making them difficult to harvest. Farmers use different harvesting methods depending on the size of their planting.

[0003] At present, the commonly used methods for harvesting water chestnuts in my country are:

[0004] (1) Water chestnuts are harvested by manual digging using simple farm tools.

[0005] (2) Large-scale fully automatic water chestnut harvesters are used for harvesting. The working principle of the harvester is soil plowing and vibration squeezing type mud-fruit separation or spring roller type mud-fruit separation.

[0006] The above method (1) is laborious and time-consuming to harvest water chestnut fruits. Farmers have high labor intensity and low labor efficiency. In addition, the fruit damage rate of manual digging and harvesting is as high as about 15%, and the fruit loss rate is about 10%. One acre of land requires 20-25 workers per day.

[0007] Compared with method (1), although method (2) realizes the harvesting method of fully automatic mechanized agricultural machinery and is highly efficient, the equipment investment cost of harvesting water chestnuts using this method is too high, which increases the economic burden on farmers.
