Detailed Description

Referring now to the drawings in the specification, in conjunction with specific embodiments, there is illustrated the following: a device is picked to vibrating fruit, including skeleton 1, pivot A2, pivot B3, eccentric block A4, eccentric block B5 and engine 8. The inside of skeleton 1 rotates through the bearing and is provided with pivot A2 and pivot B3, be provided with eccentric block A4 between two parties on the pivot A2, the both ends of pivot B3 correspond respectively and are provided with eccentric block B5, eccentric block B5 is located the both sides of eccentric block A4. One end of the rotating shaft A2 is provided with a gear A6 through a bearing, one end of the rotating shaft B3 is provided with a gear B7 meshed with the gear A6 through a bearing, and the other end of one of the two rotating shafts is connected with an engine 8. The engine 8 can be connected with the rotating shafts in a speed reducer 9 transmission mode, a belt transmission mode or a gear transmission mode and the like, the engine 8 drives one rotating shaft to rotate, and then the other rotating shaft is driven to rotate through the gears A and B, so that the rotating shafts A and B rotate together. The fixing device is characterized in that fixing parts 10 are respectively arranged on two sides of the bottom surface of the framework 1, tree pressing plates 11 are arranged on the fixing parts 10, and the fixing parts 10, the tree pressing plates 11 and the bottom surface of the framework 1 are matched with each other to form a fixing space of a tree.

Further, the eccentric block A4 and the eccentric block B5 have the same structural form, and the eccentric moment of the eccentric block A4 is equal to the sum of the eccentric moments of the two eccentric blocks B5.

Further, the fixing portion 10 is formed by arranging a plurality of fixing rods, and the tree trunk is arranged between the two rows of fixing rods and fixed through a tree trunk pressing plate 11.

The utility model discloses a theory of use: in practical use, the periphery of the framework can be provided with a light protective outer skin to play a protective role. The tree pressing plate 11 is removed, the device is placed on the tree, namely the fixing parts 10 are located on two sides of the tree, the device is inserted on the tree, the fastener is used for installing the tree fixing plate 11 after the device is placed, the device is firmly fixed on the tree, and finally the worker starts the engine 8 to start operation.

After the engine 8 is started, one rotating shaft is driven to rotate, and then the other rotating shaft is driven to rotate through the gears A and B, so that the rotating shafts A and B rotate relatively at a high speed. When the rotating shaft rotates, the eccentric blocks on the rotating shaft rotate together, namely the eccentric block A4 and the two eccentric blocks B5 rotate relatively, namely the rotating speed of the eccentric block A4 is the same as that of the eccentric block B5, and the rotating directions are opposite. When the eccentric block rotates, the eccentric moment of the eccentric block A4 around the rotating shaft A2 is equal to the eccentric moment of the two eccentric blocks B5 around the rotating shaft B3, and the initial states of the eccentric block A4 and the two eccentric blocks B5 need to be consistent. Therefore, in the rotating process of the eccentric block, the device drives the tree rod to generate high-frequency vibration, namely, shaking force to the front and the back of the tree rod is generated, and the picking operation of fruit trees is finished by the shaking force.

The working vibration frequency of the device is required to be in two intervals of 1-12 HZ and 17-25 HZ. In actual operation, the worker can correspond to the two resonance frequency intervals by replacing the engines with different powers.

After the vibration frequency used in practice is determined, the method for determining the eccentricity and the shaking force of the device is as follows:

the eccentric moment is M = mgr, wherein M is the eccentric moment N.M, M is the eccentric mass kg, r is the eccentric distance M, and g is the gravity acceleration.

According to the experimental result, the effect of adopting m ≧ 15kg and the eccentric distance r ≧ 0.05m for general fruit trees is good, and if the fruit trees with thicker trunks need to be picked, m and r need to be increased.

The calculation formula of the shaking force is as follows: f = mr ω 2, F is the shaking force N, ω is the eccentric mass angular velocity rad/s. Calculated as m =15kg, r =0.05m, vibration frequency 12 HZ:

f = mr ω 2 × 10-3=15 × 0.05 ≈ 2 × 3.14 × 12 ≈ 4259 (cows).

When the tree is shaken back and forth with 4259 newtons, with a frequency of 12HZ, the general fruit tree fruit can be shaken off. If the fruit can not be harvested by vibration, the function of harvesting the fruit can be achieved by increasing the eccentric moment M or increasing the rotating speed to be within the range of (17-25 HZ), or simultaneously increasing the eccentric moment M and increasing the rotating speed to be within the range of (17-25 HZ).

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
