Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a strawberry non-destructive harvesting device. Background Technology

[0002] Existing strawberry picking equipment has the following disadvantages:

[0003] 1. After holding the strawberry with two clamping arms, forcefully pull or yank it away from the plant, as in patent CN116548178 A. This harvesting method can easily damage the strawberry plant and affect its subsequent growth.

[0004] 2. Even if there is a cutter, it is set on the left and right sides opposite to the two clamping arms, and the strawberry stem is cut off by moving in opposite directions, as in patent CN108901345A. Since most strawberry fruits are arranged horizontally and parallel, in this structure, either the horizontal movement of the cutter will damage the adjacent fruits, or the adjacent fruits will affect the movement of the cutter, and unripe fruits will also be cut off.

[0005] 3. Although existing strawberry picking machines can use visual recognition mechanisms to distinguish and select ripe strawberries by recognizing the color of the strawberry surface, the phenomenon of mispicking and missing strawberries is still very common due to the relatively dense growth of the fruit. Utility Model Content

[0006] To address the aforementioned problems, this utility model discloses a strawberry harvesting device that uses a vertically arranged bracket and a cutting blade to separate mature strawberries from other strawberries in a vertical direction before cutting and harvesting, achieving precise and damage-free harvesting.

[0007] A strawberry harvesting device without damage includes a frame, with multiple sets of brackets for supporting the fruit stems slidably arranged at the lower part of the frame, and grooves provided on the upper surface of the brackets. Multiple sets of cutting blades that cooperate with the grooves are slidably arranged at the upper part of the frame.

[0008] Preferably, each bracket and the frame are provided with a first horizontal drive mechanism and a first vertical drive mechanism that are interconnected.

[0009] Preferably, a second horizontal drive mechanism is provided between each set of cutters and the frame.

[0010] Preferably, a second vertical drive mechanism is provided between each set of cutters and the second horizontal drive mechanism.

[0011] Preferably, the first horizontal drive mechanism, the second horizontal drive mechanism, the first vertical drive mechanism, and the downward drive mechanism are all electric push rods or cylinders.

[0012] Preferably, the bracket is a V-shaped bracket.

[0013] Preferably, the front end of the bracket is provided with a visual recognition system.

[0014] Preferably, the rear ends of multiple sets of brackets are connected to a fruit storage box.

[0015] Preferably, the side of the fruit storage box that connects to the bracket has a flexible structure.

[0016] Preferably, the bottom of the fruit storage box is an inclined surface that slopes downward from the bracket side to the frame side.

[0017] Beneficial effects

[0018] This invention features multiple horizontally and vertically movable brackets on the side of the frame. These brackets selectively lift the stems of ripe strawberries, while a cutting blade at the top moves downwards and inserts into a groove to cut the stem. The entire device harvests selected strawberries vertically by selectively cutting the stems, without damage or accidental picking. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figure 1-2As shown, this utility model discloses a strawberry non-destructive harvesting device. This device breaks through the technical barrier of cutting the fruit stem by horizontal movement of the cutter or by directly pulling and tearing the fruit stem in the prior art. It creatively uses a bracket 2 to lift the mature strawberry and separate it from the surrounding fruit. Then, the cutter 1 and the bracket 2 move up and down relative to each other to cut the fruit stem. The whole process will not damage the fruit due to the horizontal movement of the cutter, nor will it damage the seedlings.

[0025] The entire device still adopts the form of a walking robot driven by existing technology, and a visual recognition system is installed at the front end of the bracket 2 to identify ripe strawberries. These technologies are all known existing technologies, and those skilled in the art can apply them to the device of this application to achieve the technical effect of automated strawberry picking.

[0026] The device includes a frame 5, which is a hollow frame structure with strong sturdiness and stability, and can firmly support and fix the cutter 1 and the bracket 2. Multiple sets of first horizontal drive mechanisms 4 are installed in a straight line on the crossbeam at the lower part of the frame structure. At the end of each set of first horizontal drive mechanisms 4 is a set of first vertical drive mechanisms 3. At the upper end of each set of first vertical drive mechanisms is a bracket 2, which has a V-shaped structure at the top, and can lift the fruit stem to the bottom of the inner groove of the V-shaped structure. A groove is machined on the upper surface of the V-shaped structure to accommodate the cutter 1, which works in conjunction with the cutter to cut the fruit stem.

[0027] Multiple sets of second horizontal drive mechanisms 7 are installed in a straight line on the crossbeam at the top of the frame structure. The installation positions correspond to the first horizontal drive mechanism 4. At the end of each set of second horizontal drive mechanisms 7, a set of tool holders 6 are installed. The tool holders are in the shape of an inverted U. The cutter 1 is installed in the inner groove of the inverted U-shaped structure and is fixed to the tool holders 6 by at least two screws.

[0028] A fruit storage box 8 is connected to the rear end of multiple sets of brackets 2. The bottom of the fruit storage box is an inclined surface that slopes downwards from the bracket towards the frame. The two side walls of the fruit storage box and the side wall away from the bracket 2 are rigid structures, while the side of the fruit storage box 8 connected to the bracket 2 is a flexible structure. The flexible structure takes into account that all the first horizontal drive mechanisms 4 do not move simultaneously, so their horizontal positions are inconsistent. However, no matter which set of first horizontal drive mechanisms 4 moves to the front end closest to the fruit stem, the side wall of the fruit storage box 8 can be made to be close to the bracket 2 under the deformation of the flexible structure. In this way, the fruit with the stem cut off can fall freely into the fruit storage box 8. Since the bottom is a cutting inclined mechanism, the fruit will slide to the bottom of the box, reducing collision damage.

[0029] As a preferred embodiment, the first horizontal drive mechanism, the second horizontal drive mechanism, and the first vertical drive mechanism are all configured as electric push rods or cylinders.

[0030] As a preferred option, since the bracket 2 cannot lift the fruit stalk indefinitely, otherwise it will cause pulling damage to the seedlings, a second vertical drive structure that can move vertically can be added to the support of the knife holder 6 and the second horizontal drive mechanism 7.

[0031] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
