Background technique

Our country has a vast land area, fertile soil, abundant sunshine time, and humid temperate climate are very suitable for the growth of apples, pears, oranges, oranges, sand fruits, grapes and other fruits. In the golden autumn season, heavy fruits are hung on the branches. When picking, the fruit grower needs two hands to cooperate, one hand to hold the fruit, and the other hand to cut with scissors or a wallpaper knife. The work efficiency is low and the labor intensity is high. Some fruits, such as big-headed pears and grapes, have a soft surface, which is easy to damage the surface during handling, and is perishable and deteriorated, which affects the quality of the fruit and increases the economic loss of the fruit grower. For the fruit automatic identification picking machine, due to its complicated mechanical structure, low automatic identification degree, slow picking speed and high price, it is currently in the development stage. Therefore, present broad fruit grower also does not have simple, convenient, efficient picking tool.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the technical solutions in the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the utility model. Obviously, the described embodiments are the embodiment of the utility model. Some of the embodiments are novel, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Fig. 1, the portable fruit picking pliers of the present utility model comprises the clamp body 1 of scissors fork structure, the clamping mechanism that is connected at the front end of clamp body 1, the cutting mechanism that is arranged on the clamping mechanism and is used for holding the scissors fork structure The clamp body 1 is always in the restoring force mechanism of the open state; the clamp body 1 is composed of two scissor arms connected by a pin 4, which is used to provide the original force for clamping and picking.

Clamping mechanism comprises pin one 4, pin two 5, elastic clip body 9, pin five 13, hinge shaft two 14, clamp 15 and connecting rod 7, and described clamping mechanism is connected to clamp body 1 front end by Two elastic clamp bodies 9 capable of elastic deformation and two clamps 15 hingedly connected to the ends of the elastic clamp body 9 through the hinge shaft 2 14 are composed of two elastic clamp bodies 9 riveted on the front end of the clamp body 1 by rivets 6 respectively , which is an arc-shaped structure made of elastic material; the rear ends of the two clamps 15 are respectively connected to the connecting rod 7 through the pin five 13, and the other ends of the two connecting rods 7 are connected together through the pin two 5; the mechanism is used for Grips the stem of the fruit.

The cutting mechanism comprises bearing pin three 8, crank 10, hinge axis one 11, bearing pin four 12 and pendulum shearing 16, and cutting mechanism is by the crank 10 that one end is hinged with an elastic clip body 9 by hinge axis one 11 and by pin four 12 The pendulum shear 16 installed on a connecting rod 7 is composed of the other end of the crank 10 and the rear end of the pendulum shear 16 through a pin 3 8. The pendulum shear 16 is close to the surface of the clamp 15 and swings by being pulled by the crank 10. This mechanism Used to cut fruit stems.

The restoring force mechanism is composed of pillars 2 arranged inside the two scissor arms and a spring 3 connected between the two pillars 2, and is used to keep the clamp 15 in an open state all the time. .

As shown in FIG. 2 , the inner surface of the tongs 15 is provided with a texture, and the textured surface is conducive to improving the friction between the surface of the tongs and the handle of the fruit.

It is a fruit picking tool suitable for woody plants such as apples, pears, oranges, and sand fruits, and vines such as grapes. It adopts the transmission form of crank pendulum shears and connecting rod mechanism, and has the functions of clamping and picking. When picking, first extend the opened clamp 15 of the picking pliers to the handle of the fruit, the thumb and the remaining four fingers simultaneously press the clamp bodies 1 on both sides, and the clamp 15 shrinks toward the fruit handle under the drive of the elastic clamp body 9, until it contacts and grips the fruit handle. Connecting rod 7 can rotate around bearing pin two 5 and bearing pin five 13, is used for guaranteeing that two clamps 15 move in parallel to the fruit handle all the time. Continue to press the clamp body 1, the elastic clamp body 9 is deformed under the action of the clamping force, and the radian decreases, and the crank 10 is pushed to rotate clockwise around the hinge axis 11, thereby driving the pendulum shear 16 to rotate counterclockwise around the pin axis 12 to complete Clipping of the stem of the fruit to separate the fruit from the branch. The fruit clamped by the clamp 15 is moved to the storage box, four fingers are released, the clamp body 1 opens the clamp 15 under the restoring force of the spring 3, and the fruit is placed in the storage box to complete a picking work.

When the picking pliers are installed, only the crank 10 and the pendulum shears 16 are connected to the elastic clamp body 9 and the connecting rod 7 on the right side respectively, so that the operating requirements of different habits of left and right hands can be met.
