Description

Technical Field

[0001] The utility model belongs to the technical field of chestnut harvesting, and in particular relates to a chestnut harvester suitable for steep mountainous areas. Background Art

[0002] Chestnut is a plant of the genus Castanea in the Fagaceae family. It is grown in many places in my country. Chestnut is rich in various nutrients, such as carbohydrates, proteins, vitamins, minerals, etc., and has high nutritional value. Chestnuts generally mature in autumn, and the specific time varies according to the variety and geographical location. Usually when the chestnut's involucre turns from green to yellow and begins to crack, it indicates that the chestnuts are mature and can be harvested.

[0003] For example, the Chinese patent with the publication number CN216437998U discloses a portable chestnut harvester, including a hand bar, a sickle cutter and a shovel cutter: a docking short bar is arranged on the left side of the hand bar, a fixed thread groove matching the hand bar is provided on the right side of the docking short bar, a round hoop is arranged at the bottom of the docking short bar, a net bag is provided on the surface of the round hoop, a mounting assembly is arranged in the inner cavity of the round hoop, a connecting screw is welded on the right side of the sickle cutter and the shovel cutter, a tool connecting groove matching the connecting screw is provided on the left side of the docking short bar, and a flashlight fixing sleeve is fixedly connected to the top of the docking short bar. The utility model removes chestnut fruits through the coordinated use of the hand bar, the sickle cutter and the shovel cutter, and at the same time, the round hoop and the net bag are used to collect the fallen chestnut fruits, so as to achieve the purpose of convenient and efficient use and convenient high-altitude picking.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used. For example, when harvesting chestnuts, the user needs to pull the hand lever hard, which will drive the sickle cutter to cut the chestnut stalks. Pulling hard can easily cause the chestnut tree to shake and be damaged. In addition, when chestnut trees are planted on steep slopes, the user places the device on the ground. Under the action of gravity, the device will slide down on the ground, requiring support from the user, which is troublesome. In view of this, we propose a chestnut harvester suitable for steep slopes. Utility Model Content
