Description

[Technical field]

[0001] The invention relates to the technical field of fruit picking tools, in particular to a pair of single-grip wrist-force driven fruit picking scissors. [Background technology]

[0002] In the production of fruits, harvesting and picking is the most time-consuming, labor-intensive and extremely important link in the entire production. According to statistics, the labor required during fruit harvesting accounts for about 50%-70% of the entire production process. The quality of picking operations directly affects the storage, processing and sales of fruits, which ultimately affects the market price and economic benefits. At present, the fruit picking device mainly includes a manipulator equipped with machine vision, which completes the fruit picking operation through the manipulator. Due to the obstruction of leaves and branches, the success rate of judging fruits through machine vision is low, the execution efficiency is low, and the possibility of missing picking is high. In addition, the manipulator needs to design a software program separately, and the manipulator needs to avoid larger branches during the picking operation. This places high demands on the mechanical design and motion control of the manipulator, resulting in high manufacturing costs for the manipulator and inconvenience for promotion. Therefore, Chinese fruit farmers are still using the traditional pure manual picking method. However, fruit farmers who adopt manual picking generally use ordinary gardening scissors. The disadvantage is that the range of picking fruit with traditional gardening scissors is small and requires the coordinated operation of both hands. When picking fruits at higher places, each time a fruit is picked, it is necessary to tiptoe to pull down the fruit branch, resulting in low picking efficiency and high labor intensity.

[0003] In summary, there is still much room for improvement in the current fruit picking method. [Summary of the invention]

[0025] See also Figures 1 to 3 As shown, the present invention provides a single-grip wrist force driven fruit picking scissors, comprising a handle 1, a fixed shearing blade 2, a movable shearing blade 3, a hexagon socket screw 4, a gasket 5, a nut 6, a height adjustment bolt 7, a rivet 8, an arm fixing plate 9 and a connecting member 10. The handle 1 is movably connected to the connecting member 10 through the hexagon socket screw 4, the connecting member 10 is fixedly connected to the movable shearing blade 3 through the hexagon socket screw 4, the handle 1 and the connecting member 10 are arranged below the fixed shearing blade 2 and at the front end of the arm fixing plate 9, the fixed shearing blade 2 and the movable shearing blade 3 are movably riveted through the rivet 8, the movable shearing blade 3 keeps in contact with the fixed shearing blade 2 and is located above it, the fixed shearing blade 2 is fixedly connected to the arm fixing plate 9 through the height adjustment bolt 7, the gasket 5 and the nut 6, and the arm fixing plate 9 is fixed to the arm through a double canvas belt or other flexible belts or devices that can be used for fixing.

[0026] There are eight washers 5, six nuts 6, two height adjustment bolts 7, and two hexagon socket screws 4. The arm fixing plate 9 is provided with four holes and slots, through which double canvas belts or other flexible belts for fixing can pass, which is convenient for connection and can improve the reliability of fixing the arm fixing plate 9 to the arm.

[0027] A hole slot is respectively provided at both ends of the handle 1, and a double canvas belt or other flexible belt can pass through the hole slot to form a closed loop with the handle 1, which can ensure the smooth closing and opening of the fruit picking shears.

[0028] The rear side of the arm fixing plate 9 is provided with two ear-shaped structures with through holes, which are convenient for fixing and connecting with the fixed shear blade 2 through the height adjustment bolt 7, the gasket 5 and the nut 6. The fixed shear blade 2 is provided with a protruding structure higher than the blade plane. After the scissors are closed, the side plane of the protruding structure fits with the side plane of the movable shear blade 3. After the scissors are opened, the side plane of the protruding structure forms a certain angle with the side plane of the movable shear blade 3, and the angle range is generally 0-50 degrees, which plays a limiting role on the movable shear blade 3 during the shearing process.

[0029] The fixed shear blade 2 is provided with two ear-shaped structures with through holes, which are convenient for fixing and connecting with the arm fixing plate 9 through the height adjustment bolt 7, gasket 5, nut 6. The handle 1 is in the shape of an inwardly concave arc, and the surface is coated with a layer of soft material, which can not only improve the comfort of contact with the fingers, but also play a certain protective role on the fruit.

The number of gaskets 5 and nuts 6 used in the connection is eight and six respectively, which can realize the function of height adjustment.

[0030] The fixed shear blade 2 and the movable shear blade 3 are riveted together by rivets 8. The edges of the fixed shear blade 2 and the movable shear blade 3 are twisted at a small angle, which facilitates good contact between the edges of the fixed shear blade 2 and the movable shear blade 3 during work, thereby improving the sharpness of the picking shears. The movable shear blade 3 and the connecting piece 10 are fixedly connected by a hexagon socket screw 4, and the handle 1 and the connecting piece 10 are movably connected by a hexagon socket screw 4, which conforms to the ergonomic design.

[0031] like Figure 3As shown, when using the single-grip wrist-driven fruit picking scissors, the picker first inserts the four fingers except the thumb into the closed loop formed by the handle 1 and the double canvas belt or other flexible belt, then passes the purchased double canvas belt through the hole groove on the arm fixing plate 9, and fixes the arm fixing plate 9. After the above operations, the single-grip wrist-driven fruit picking scissors are put on. In the process of holding the fruit with one hand, the fruit stem has entered the area clamped by the fixed shearing blade 2 and the movable shearing blade 3. The wrist driving force can be transmitted to the movable shearing blade 3 through the handle 1 and the connecting piece 10, so that the movable shearing blade 3 rotates relative to the fixed shearing blade 2 to achieve the shearing of the fruit stem. After the fruit stem is cut off, the fruit is still in the state of being held by the palm, and can be put into the fruit basket at will, completing the whole process of fruit picking.
