Description

Technical Field

[0001] The utility model belongs to the technical field of fruit tree harvesting, and particularly relates to an eccentric vibration mechanism for clamping fruit tree trunks. Background Technique

[0002] Orchard harvesting operations are an important part of the orchard production process. At present, fruit harvesting in orchards in China mainly relies on manual picking by hand, knocking with sticks, and using simple tools such as fruit knives. The production efficiency is low, the labor intensity is high, the amount of labor used is large, and the cost is high. Existing vibration harvesting equipment mainly uses micro power, including electric, pneumatic, and small gasoline engines, and is carried on the back or slanted across. The vibration operation of a single branch of the fruit tree is carried out by holding a vibration rod by hand. None of the above harvesting methods can meet the harvesting operations of large-scale orchards.

[0003] Existing mechanical vibration type fruit tree clamping and collecting devices often have problems such as large rigidity, inconvenient adjustment of exciting force, and relatively large damage to the tree trunk. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an eccentric vibration mechanism for clamping fruit tree trunks in view of the deficiencies of the above-mentioned existing technologies. This eccentric vibration mechanism is designed according to the non-resonant two-shaft inertial vibration machinery theory. Two eccentric blocks rotate simultaneously to generate exciting force to vibrate the fruit tree, with high exciting efficiency, improving the efficiency of fruit tree harvesting, and can be widely promoted and applied.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: an eccentric vibration mechanism for clamping fruit tree trunks, characterized in that it includes a housing, the housing is composed of two steel plates, a vibration mechanism is arranged inside the housing, the vibration mechanism is arranged between the two steel plates, first pin shafts are fixedly installed on both sides of the bottom of the housing, electric push rods are hinged on the first pin shafts, second pin shafts are fixedly installed on both sides of the top of the housing, triangular blocks are hinged on the second pin shafts, the top end of the output shaft of the electric push rod is hinged with the triangular block, and a clamping arm is fixedly installed at the top end of the triangular block.

[0006] The triangular block is connected to the second pin shaft, the top end of the output shaft of the electric push rod and the clamping arm at its three vertexes respectively. The electric push rod can push the triangular block to rotate, driving the clamping arm to open and close to clamp the fruit tree.

[0007] A first sleeper is fixedly installed on the clamping arm, and a second sleeper is fixedly embedded on the housing, and the second sleeper is located between the second pin shafts. The fruit tree trunk is clamped between the first sleeper and the second sleeper by the clamping arm, and the vibration is transmitted from the first sleeper and the second sleeper to the tree trunk through the vibration mechanism to vibrate the fruit tree, causing the fruit on the tree to fall.

[0008] The two first sleepers respectively form a V-shaped structure with the body support part. The first sleeper and the second sleeper clamp the fruit tree in three directions, with firm clamping, avoiding the problem of large contact force in flat clamping.

[0009] Preferably, the vibration mechanism includes two rotating shafts, which are rotatably inserted into the shell through bearing seats. Eccentric blocks are fixedly installed on the rotating shafts. The radius of the eccentric blocks is 148 mm. The two rotating shafts are drivingly connected, and one of the rotating shafts 9 is drivingly connected to a servo motor, and the power of the servo motor is not less than 2.84 kw.

[0010] Driven by the servo motor, the two rotating shafts rotate, and the two eccentric blocks also rotate accordingly. At the same time, exciting forces are generated by rotation. The exciting forces are transmitted to the clamping arms, the first sleeper and the second sleeper through the shell to vibrate the fruit tree.

[0011] Preferably, sprockets are fixedly installed on the rotating shafts, and the sprockets are drivingly connected by chains. Under the action of the sprockets and the chains, the two rotating shafts rotate synchronously in the same direction.

[0012] Preferably, a controller for controlling the servo motor is fixedly installed outside the shell. The power and speed of the servo motor can be adjusted through the controller, so as to control the magnitude and frequency of the exciting force, and the vibration parameters of the fruit tree can be adjusted according to the size of the fruit tree.

[0013] Preferably, a group of mounting holes are provided on the clamping arm, multiple groups of mounting holes are provided on the triangular block, and mounting bolts are arranged in the mounting holes. The connection position between the clamping arm and the triangular block can be adjusted, so as to adjust the distance between the two clamping arms and the distance from the clamping arm to the rotation center, so as to increase the range of clamping the tree trunk, make the clamping point always in a suitable position, and reduce the damage to the bark during vibration.

[0014] Preferably, clamping plates are fixedly installed on both sides of the clamping arm, and the first sleeper is fixedly installed between the clamping plates. The first sleeper is fixed on the clamping arm through the clamping plates. The first sleeper and the second sleeper are covered with protective pads, which play a role in protecting the bark, avoiding direct contact between the tree trunk and the clamping arm, and reducing the impact force at the same time.

[0015] The utility model has the following advantages compared with the prior art:

[0016] In the utility model, two electric push rods are used to push the clamping arms to rotate, so that the second sleeper and the two first sleepers clamp the fruit tree.
