Strawberry was widely planted in most parts of the world, and by 2022, the total yield of strawberries in our country was the first in the world. Strawberry is a high nutrition crop, is popular with consumers, but has high production cost and high labor cost, meanwhile, the strawberry picking period is short, if the strawberry is not picked in time, the strawberry is too ripe to eat, and the burden of fruit farmers can be increased. Moreover, china is in the world midstream in the aspects of automatic picking and mechanized planting, mainly manual picking. This is the greatest cost to the strawberry grower and is also a great operational uncertainty. In order to improve the strawberry picking efficiency, reduce the strawberry picking cost, accelerate the development of strawberry planting industry and improve the economic benefit of fruit farmers, a plurality of strawberry picking robots are appeared in the last year.
The strawberry picking robot is usually provided with a necessary cutter/cutting tool, the cutter is arranged on the manipulator, and the manipulator drives the cutter to move to a target picking position to cut and pick target strawberries. For example, patent application number 202211523065.5 discloses a cross-ridge parallel arm strawberry picking robot and a control system and picking method thereof; patent application number 202210450789.5 discloses a cross-ridge double-arm cooperative strawberry harvesting robot, a control system and a picking method. The shearing effect of a shearing device/shearing tool on the existing strawberry picking robot on the strawberry stems is to be improved, and the strawberry stems cannot be well clamped and positioned.

The utility model is realized by the following technical scheme:
the utility model provides a cutter for picking strawberry, includes blade holder, moves sword, stationary knife, shearing steering wheel and moves sword buffer block, wherein, the stationary knife is fixed to be set up on the blade holder, and shearing steering wheel installs on the blade holder, moves the sword setting and is in stationary knife one side and with the output shaft of shearing steering wheel, drives the rotation of moving the sword through shearing steering wheel, realizes with stationary knife separation and reunion action; the inner side surface of the fixed knife is provided with a knife edge groove, and correspondingly, the inner side surface of the movable knife is provided with a knife edge; a spring buffer block is arranged on the inner side of the movable knife; the inner side of the outer end of the movable knife is also provided with a guide hook.
In the technical scheme, the shearing steering engine is arranged on the cutter seat through the shearing steering engine supporting plate.
In the technical scheme, when the fixed knife and the movable knife are closed, the knife edge is inserted into the knife edge groove.
In the above technical scheme, the spring buffer block comprises a buffer block, the buffer block is embedded in the mounting cavity at the inner side of the movable cutter through a spring, and when the fixed cutter and the movable cutter are closed, the buffer block can enter the mounting cavity at the inner side of the movable cutter.
The utility model has the advantages and beneficial effects that:
the utility model has simple structure, only adopts a simple steering engine to drive, and is provided with a spring buffer block at the inner side of the movable knife, when the fixed knife and the movable knife are closed, the buffer block can enter into an installation cavity at the inner side of the movable knife; the spring buffer block has the functions that: firstly, the buffer function is achieved when the movable knife and the fixed knife are closed, so that the hard collision of the movable knife and the fixed knife is prevented, and the knife and the shearing steering engine are prevented from being damaged; secondly, in the closing process of the movable knife and the fixed knife, the spring buffer block clamps the strawberry stalks between the spring buffer block and the fixed knife, and then the strawberry stalks are sheared, so that the shearing effect is ensured, and the phenomena that the strawberry stalks slide into the cutting edge groove in the shearing process to cause the strawberry fruits to move upwards to touch the knife to cause the damage of the strawberry fruits and the continuous shearing are avoided; thirdly, after the movable knife and the fixed knife are completely closed, the sheared strawberry stalks can be clamped between the spring buffer blocks and the fixed knife, so that the strawberry fruits are prevented from falling off, and the shears are moved to the position of the collecting box to be discharged through a moving device (a moving device such as a mechanical arm, and the shears are arranged on the mechanical arm).
