Description

Technical Field

[0001] The invention relates to the technical field of agricultural picking, and in particular to an agricultural fruit picking device. Background Art

[0002] The traditional method of picking fruits is manual picking, which is complicated and labor-intensive. In the forest garden, the traditional method for picking mature fruits such as dates and ginkgo nuts is to use a pole to hit the branches to make the mature dry fruits fall from a height and then collect them into containers, which has low work efficiency. In order to improve work efficiency, a "vibration picking machine" (patent number "200820135334.X") is disclosed in the Chinese patent specification. This hand-held picking machine uses high-frequency oscillation to make the fruits fall quickly. Although it is not hit with a pole, it still needs to touch the upper part of the tree little by little by hand, and the length of the pole is fixed and unchanged. The picking height is limited, so its picking efficiency is still not high. For example, the Chinese patent specification also discloses a "vibration fruit tree harvester" with a patent number of "200820125040.9". This vibration fruit tree harvester consists of a fruit tree shaking device, a hydraulic control system, a fuel tank and a counterweight, and is characterized in that: the fruit tree shaking device is installed in a large The front end of the 44kw tractor includes left and right side brackets, a main beam frame, a telescopic arm, a vibration head suspension frame and a clamp-type vibration head. The hydraulic control system is installed on the right side bracket of the fruit tree shaking device within the reach of the tractor driver. The fuel tank and counterweight are three-point mounted on the back of the tractor. Although one person can operate the machine, it has good maneuverability and a fast fruit picking speed. The mechanical vibration of the harvester will not damage the trees. Effective mechanical operation replaces manual labor, thereby saving labor and improving harvesting efficiency. However, the machine consists of a fruit tree shaking device, a hydraulic control system, a fuel tank and a counterweight. Not only is the mechanical structure complex, the manufacturing cost is high, and the equipment requires a large working space. It is only suitable for fruit picking with a large working space around the fruit trees.

[0003] When picking fruit, the existing agricultural fruit picker generally fixes a clamp-type vibrating head at the bottom of the fruit tree, vibrates the ripe fruits on the fruit tree to drop, and sets a tarpaulin at the falling point of the ripe fruits to collect the ripe fruits. However, during the collection process, due to the different heights of the fruit trees, when collecting, the higher fruit trees are vibrated, and the fruits are easily separated from the tarpaulin at the bottom during the vibration and fall, which increases unnecessary fruit collection losses and is inconvenient for users.

[0014] Beneficial effects:

[0015] 1. When picking ripe fruits on the fruit tree body, the present invention uses a positioning vibration mechanism to vibrate and shake down the ripe fruits on the fruit tree body, and opens two sets of driving motors at the top of the mounting frame, so that the motor driving shaft drives the connecting plate and the clamping plate to rotate, and the fruit tree body is clamped and fixed by the two sets of clamping plates. Elastic sponges are installed on the inner walls of the two sets of clamping plates to prevent the fruit tree body from being damaged during the clamping process of the two sets of clamping plates. After the fruit tree body is clamped and fixed by the two sets of clamping plates, the exciter inside the mounting chamber is opened, and the exciter drives the mounting frame and the fruit tree body to vibrate, so that the ripe fruits on the top of the fruit tree body will automatically fall off, and the picking of the fruits is completed. Compared with traditional manual collection, this solution greatly improves the efficiency of fruit picking;

[0016] 2. When the present invention collects the ripe fruits on the fruit tree body by vibration, the fallen fruits are collected by positioning the collection mechanism to prevent the fruits from falling to the work site and being difficult to collect, and the ripe fruits are also easily damaged. By turning on the two sets of adjustment motors, the rotating shaft drives the mounting plate and the first adjustment frame to rotate in the direction of the fruit tree body. At the same time, the first extension arm and the second extension arm can be adjusted according to the size of the fruit tree body. By turning on the first driving cylinder and the second driving cylinder respectively, the first extension arm and the second extension arm are telescopically adjusted inside the first mounting groove and the second mounting groove, so that the collection tarpaulin is unfolded at the bottom of the fruit tree body by the first tarpaulin mounting rod, the second tarpaulin mounting rod, the third tarpaulin mounting rod, the fourth tarpaulin mounting rod and the fifth tarpaulin mounting rod, and the fallen ripe fruits are collected by the collection tarpaulin;

[0017] 3. When collecting ripe fruits, the present invention uses a tarpaulin lifting mechanism to lift the tarpaulin to prevent the fruits from falling outside the collecting tarpaulin during vibration due to the high fruit tree body. After the collecting tarpaulin is adjusted to a suitable use position, the first driving electric cylinder, the second driving electric cylinder and the third driving electric cylinder inside the first fixing frame, the second fixing frame and the third fixing frame can be opened respectively, and the lifting tarpaulin can be driven to move upward through the upper mounting rod, the first mounting rod and the second mounting rod, so that the lifting tarpaulin is pulled up and raised around the fruit tree body, thereby preventing the ripe fruits from falling outside the collecting tarpaulin when the fruit tree vibrates, thereby increasing the fruit collection rate and reducing unnecessary fruit loss.

At the same time, the first extension arm 806 and the second extension arm 811 can be adjusted according to the size of the fruit tree body 6, and the first driving cylinder 807 and the second driving cylinder 812 are turned on respectively so that the first extension arm 806 and the second extension arm 811 are in the first mounting groove 805 and the second mounting groove 81 0 internal telescopic adjustment, so that the collecting tarpaulin 821 is deployed at the bottom of the fruit tree body 6 through the first tarpaulin mounting rod 813, the second tarpaulin mounting rod 814, the third tarpaulin mounting rod 815, the fourth tarpaulin mounting rod 816 and the fifth tarpaulin mounting rod 817.

Compared with traditional manual collection, this solution greatly improves the efficiency of fruit picking.

[0038] When the ripe fruits on the fruit tree body 6 are picked, the present scheme shakes the ripe fruits on the fruit tree body 6 by vibrating the positioning vibration mechanism 7.
