Embodiment Construction

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

[0035] The physical characteristics of tomato are the research basis of picking operation, which determines the scheme design of simple tomato picking device. Each bouquet of ordinary tomatoes generally has 3 to 5 fruits. When farmers pick the tomatoes, they need to pick off the tomatoes instead of leaving the flower stalks on them.

[0036] Hand-picked tomatoes rely on the pressure of the hand on the flower stalk to provide friction and balance the force of picking tomatoes, so a lot of pressure is required, and the hand that holds the flower stalk will be worn to a large extent. Therefore, by changing the way of applying force in the process of picking tomatoes, the burden on the hands can be reduced.

[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 stru...

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 of the farmers directly pick it by hand, holding the flower stem with one hand and picking it with the other hand. Even if some farmers use scissors to cut off the flower stalks, but because the flower stalks of tomatoes have a bitter taste, they must be removed before going on the market. The tomatoes sold in the market have no flower stalks, so the cut tomatoes need to be removed and left behind. The peduncle on the tomato, which still wears and festers the hands. Since the friction force provided by the hand against the handle is balanced with the force of picking tomatoes, the fingers are required to provide a lot of pressure and will be sub...
