Description

fruit picker

technical field

The utility model patent relates to a fruit-picking machine for agriculture and forestry, specifically a fruit-picking tool that can be hand-held, vehicle-mounted, or used as a robot arm.

Background technique

Picking fruit is a headache for fruit growers. They look at the fruit trees full of joy, but it is not easy to pick them all in good condition. Many fruit trees have tall stems and luxuriant branches. It is necessary to climb up the tree trunk or use a ladder to pick the fruit, which is not safe and difficult to handle. During the fruit picking process, the fruit may fall directly to the ground and cause damage, and it is necessary to pick the fruit from the ground, resulting in low efficiency. The fruit-picking tools used by fruit growers are basically scissors or hooks with bars, and some slightly better tools have only been improved in a certain aspect, while others are only suitable for picking a certain type of fruit. For example, the fruit picker with the patent number: 2012104415724 is only suitable for picking nuts such as chestnuts, walnuts, and torreya. It cannot effectively separate the fruit from the branches and leaves, and can only pick the branches and fruits together, and the picked fruits will fall to the ground, so it is time-consuming and laborious. .

Contents of the invention

The utility model patent will solve the above problems, which is convenient, safe and fast, does not harm the fruit itself or fruit trees, and is suitable for picking most fruits.

In order to achieve the above object, the utility model takes the following technical solutions:

The fruit picking head contains a curly blade that matches its shell. When the two rotate relative to each other, there are two basic states: open state and closed state. When in the open state, the fruit is easily inserted into the inner cavity of the fruit picking head. Because it is consistent with the shape of the shell, it will not hinder the fruit from entering the inner cavity, and the curling blade will not damage the fruit when it rotates. Once the curling blade is rotated to a certain angle, the fruit can be effectively separated from the branches and leaves, and other branches and leaves of the fruit tree are rarely cut. It does not damage the fruit tree and affect the results of the coming year. When the blade rotates to cut off the fruit stalk, the fruit with the cut off fruit stalk is kept in the relatively sealed space formed by the blade and the fruit picking head. This state is called the closed state, and the fruit will not Fall out from the entrance, but can only fall directly into the fruit basket equipped with cushions along the pipeline connected to the shell. This has not only effectively picked the fruit, but also can collect the fruit in the fruit basket in good condition. In addition, there are multiple teeth on the curling blade in the utility model, which can pick multiple fruits at the same time or in a string form, and the fruit picking efficiency is very high, so using the utility model has very good practical value for fruit farmers to pick fruits.

detailed description

The curling blade 7 is adapted to the shape of the shell 4. The outer wall of the curling blade 7 is close to the inner wall of the shell 4. When the two rotate relative to each other, there are two basic states: an open state and a closed state. In the open state, the fruit can easily enter the inner cavity of the fruit picking head 1. Closed state fruit stalk is cut off and the fruit that guarantees cut off fruit stalk can only enter fruit guide pipe 14 from outlet 5. During the fruit picking process, turn the curling blade 7 to the open state, the curling blade 7 is attached to the inner wall of the shell 4 and is on the same axis, that is, the state shown in Figure 1, the curling blade 7 is completely hidden in the shell and is close to it to form an easy Let the fruit enter the inner cavity, lift the fruit picking head 1 (manually can also be installed on the mechanical arm on other machine equipment) towards the fruit on the tree, let the fruit fully enter the cavity, and then turn the drive handle 3 to drive the transmission shaft 15, drive The shaft 15 drives the curling blade 7 to rotate again. When the curling blade 7 rotates, the fruit stalk that enters the fruit from the side of the fruit picking head will be stuck between the two teeth 8, and the branches and leaves of the tree will be difficult to be stuck and will be separated from the two teeth. Eject between 8, so just reach the effect that fruit, branch are separated, and there are some sub-teeth 8 on the curly blade 7, and side curved edge of a knife 9, therefore can take the same way to a plurality of fruits to pick at the same time, that is to say can simultaneously Pick multiple fruits and improve the efficiency of fruit picking. When the side curved knife edge 9 of the curly blade 7 is in contact with the side straight knife edge 6 of the shell 4 in the opposite direction, at this moment a relatively closed space is formed between the shell 4, the extension shell 20 and the curl blade 7, wherein the extension shell 20 Can be the continuation of shell 4 shapes, can also be other raised shapes, can adopt transparent material to observe when picking fruit conveniently, but do not hinder the rotation of curling blade 7, the state at this moment is called closed state, and curling blade 7 side curves edge 9 Cut off the fruit stalk with the side straight knife edge 6 of the shell 4, the fruit of the cut fruit stalk will remain in this closed space, will not fall out from other places, and can only flow into the fruit guide tube 14 from the outlet 5, Flow in the fruit blue (not drawn among the figure) from fruit guide tube 14 again. As the fruit that enters the inner cavity from the top, the top curved knife edge 17 (see Fig. 2 and Fig. 4) of the curling blade 7 is in relative contact with the top straight knife edge 18 on the top cover 11 to cut off the fruit stalk. Two rotation directions of the edge of a knife on the shell 4 and the curling blade 7 are distributed, which direction can be rotated from which direction is convenient for operation, and the flexibility of fruit picking is improved.
