Description

Technical fields:

[0001] This utility model relates to a power connection device for an electric hedge trimmer and a tea picker, belonging to the field of agricultural machinery technology. Background technology:

[0002] An electric hedge trimmer is a machine specifically designed for trimming hedges, lawn edges, and other landscaping projects. It's suitable for trimming various types of hedges and lawn edges. Generally, an electric hedge trimmer refers to one powered by a small gasoline engine that drives the blades to cut and rotate. Currently, hedge trimmers are divided into single-blade and double-blade types. A tea harvester is a crop harvesting machine that picks the tender tea leaves from the top of tea trees. Based on the harvesting method, they are divided into selective and non-selective tea harvesters. Selective tea harvesters include break-type and friction-type types. The former uses the principle of bending and breaking to pick tender tea leaves while preserving older branches; the latter uses a pair of elastic fingers to hold the tea leaves, relying on the static friction between the fingers and the tea leaves to pick the new leaves while preserving older leaves and buds. Due to low production efficiency and high requirements for tea garden operating conditions, selective tea harvesters have not been widely adopted.

[0003] Currently, the structural design of the power connection device for electric hedge trimmers and tea pickers on the market is not reasonable enough, making maintenance and installation cumbersome. The connection seat is fixed on the gearbox body, and it can only be replaced after disassembling the gearbox cover, connecting rod, large reduction gear, small transmission gear, and motor. This is very troublesome to operate and cannot meet people's needs. Utility model content:

[0004] To address the above problems, the technical problem to be solved by this utility model is to provide a power connection device for an electric hedge trimmer and a tea picker.

[0005] This utility model discloses a power connection device for an electric hedge trimmer and tea picker. It includes a gearbox, a main unit, a motor, a connecting seat, a transmission pinion, a reduction gear, an upper transmission linkage, a lower transmission linkage, an upper bearing, a lower bearing, tea picking blades, and a collection cover. The main unit is located on top of the gearbox and is fixedly connected by several screws. A motor connecting cavity is located inside the main unit, and a motor is housed within the motor connecting cavity. A connecting seat connecting cavity is located below the motor connecting cavity, and a connecting seat is housed within the connecting seat connecting cavity. The output shaft of the motor passes through the center of the connecting seat and is fixedly connected to the transmission pinion. The transmission pinion is located inside the gearbox, and a reduction gear is located inside the gearbox. The teeth of the reduction gear mesh with the teeth of the transmission pinion. An upper transmission linkage and a lower transmission linkage are fixed to the upper and lower ends of the reduction gear, respectively. The central shaft of the reduction gear passes through the upper and lower transmission linkages and is connected to the upper and lower bearings, respectively. Two sets of tea picking blades are fixed to the upper and lower transmission linkages, and a collection cover is fixed to the tea picking blades by screws.

[0006] Preferably, the side of the connecting seat is provided with several positioning holes 1, which are designed to be opposite to several positioning holes 2 at one end of the gearbox body, and are fixedly connected by several screws.

[0007] Preferably, one end of the gearbox is provided with a protruding rod, which is designed to be opposite to the groove on the lower side of the main unit, and the main unit is fixedly connected to the gearbox by a screw. The front end of the handle of the main unit is located at the front end of the gearbox and is fixedly connected by several screws.

[0008] The beneficial effects of this utility model are: it has a reasonable structural design, beautiful appearance, novel and unique shape, simple installation, and convenient assembly and maintenance. By separating the power part composed of motor and control system and the gear reducer part into two independent parts, and finally connecting them into a combined unit by a few screws, this design is not only easy to assemble and disassemble, but also convenient to maintain. It can be replaced without removing the gearbox cover, making it more convenient to operate and meeting people's needs. Attached image description:
