Description

A convenient rear-mounted power reciprocating push-pull nut harvester

Technical field

The utility model relates to the field of fruit picking, in particular to a convenient rear-mounted power reciprocating push-pull nut harvester.

Background technique

In my country, some specialty dried fruit industrial production bases have been formed for walnuts, chestnuts, hazelnuts, ginkgo and other specialty fruits, with considerable economic benefits. Picking and harvesting account for about 33% to 50% of the entire operation. Due to the complexity of picking operations, the degree of picking automation is still very low. At present, domestic fruit picking operations are basically performed manually. Fruit picking operations are highly seasonal, labor-intensive, and expensive. Therefore, ensuring timely and rapid harvesting of fruits and reducing harvesting operation costs are urgent problems that fruit farmers need to solve to increase their income. At present, the United States, France and other countries adopt the structure of vibrating picking machinery, which generally develops from a single fixed-stroke push shaker to inertial shakers, pneumatic shakers and other types of orchard picking machinery. However, its shaking method is single. To make the fruit fall from the branches of the fruit tree, it needs to generate sufficient vibration force, which often consumes a lot of energy and is not efficient. The clamping position is at the bottom of the trunk, close to the root of the fruit tree. Due to the power of vibration, It is relatively large and can easily cause damage to the roots of fruit trees. To this end, the industry has also successively developed a variety of nut picking equipment. For example, the Chinese utility model patent with publication number CN116058171A discloses a multi-functional nut picking machine, and specifically discloses a handheld shell, which is equipped with a power supply and control circuit board, the top of the inner cavity of the handheld housing is provided with a drive motor connected to the power supply and the control circuit board, the output end of the drive motor is provided with a drive bevel gear, and below the drive motor is provided a drive that is rotationally connected to the inner cavity of the handheld housing through a bearing. The outer edge of the drive plate is provided with an annular helical tooth portion that meshes with the drive bevel gear, and the side of the drive plate is provided with a drive rod that is rotationally connected; however, in this utility model, when the drive rod is driving the connecting piece, there is Due to the downward force, the force transmission is not linear enough, and there is a risk of damaging the connecting parts. Moreover, there is a lack of internal buffer mechanism. The rigid impact generated during the operation of the machine directly acts on the driving component, which may cause the driving component to break.
