Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the drawings.

[0035] The physical characteristics of tomatoes are the research basis of picking operations and determine the design of simple tomato picking devices. Ordinary tomatoes generally have 3 to 5 fruits in each bouquet. When picking, farmers need to pick the tomatoes and not leave the stalks on them.

[0036] When picking tomatoes by hand, the friction force against the stalks is balanced by the force of picking tomatoes. Therefore, a lot of pressure is required, and the hand holding the stalks will be worn to a great extent. So by changing the way of applying force in the process of picking tomatoes to reduce the burden on hands.

[0037] Such as Figure 1-6 As shown, a hydraulic shearing tomato picking device includes a hydraulic shearing mechanism, a slider mechanism, a tomato locking structure, and a pedicel picking and clamping structure.

[0038] The hydraulic shearing mechanism incl...

Abstract

Disclosed is a hydraulic cutting tomato picking device. The device comprises a hydraulic cutting mechanism, a sliding block mechanism, a tomato locking structure and a pedicel picking and clamping structure. The hydraulic cutting mechanism comprises a support, an arm rod, a hydraulic cylinder driver, a hydraulic oil cylinder and a support table. The sliding block mechanism comprises a straight rod and a bushing. The tomato locking structure comprises a fastening disc, racks, connecting rods, regulating rods, locking rods and a tomato sleeve. The pedicel picking and clamping structure comprises a fastening clamp, a hinge pin, a primary pedicel hole and a secondary pedicel hole. The hydraulic cutting mechanism drives a piston rod to stretch out, the tomato locking structure wraps tomatoes preliminarily, the pedicel picking and clamping structure fixes pedicels and calyx tendrils of the tomatoes, the hydraulic cutting mechanism drives the piston rod to retract, the sliding block mechanism moves in parallel, the tomato locking structure locks the tomatoes, and the sliding block mechanism cooperates with the pedicel picking and clamping structure to complete cutting of the tomatoes.

Description

Technical field [0001] The invention relates to a hydraulic shearing tomato picking device, which belongs to the technical field of agricultural equipment automation development. Background technique [0002] With the continuous increase of tomato planting area, picking tomatoes has gradually become a headache for farmers. Now most farmers pick it directly by hand, holding the stalk with one hand and picking it with the other. Even if farmers use scissors to cut the pedicels and pick them, the pedicels of tomatoes have a bitter taste, so they must be removed before they go on the market. Tomatoes sold in the market have no stalks, so the tomatoes that are cut in this way need to be removed and left behind. The peduncle on the tomato, which will still wear and fester the hand. Since it is the pressure of the hand on the handle that provides a balance between the friction and the force of picking the tomatoes, the fingers are required to provide a lot of pressure and will be worn...
