When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
With appropriate reference to fig. 1 and 2, the inertial picker according to the basic embodiment provided in the present application comprises a lever 1, a transmission 2 mounted on the lever 1, a grip 3 mounted on the upper end of the lever 1 and capable of gripping and releasing fruit tree branches, and a first driving member 4.
As shown in fig. 3 and 5, the transmission device 2 includes a bracket 21, a driving crank 22, a side link 23, a driven crank 24, a connecting rod 25, and a slider 26. The bracket 21 is fixedly mounted on the operating rod 1, and the connection mode can be a bolt connection mode, a plugging mode or a clamping mode. The two ends of the driving crank 22 are respectively hinged with the bracket 21 and the side link 23, and the driving crank 22 is in a rod shape. Wherein the driving crank 22 is hinged to the support 21, i.e. the driving crank 22 can rotate on the support 21 about its hinge axis. The driving crank 22 is hinged with the side link 23, i.e. the driving crank 22 and the side link 23 can rotate relatively.
As shown in fig. 5, the other end of the side link 23 is hingedly connected to a driven crank 24. The other end of the driven crank 24 is hinged to the bracket 21, i.e. the driven crank 24 can rotate about its hinge axis with the bracket 21.
And two ends of the connecting rod 25 are respectively hinged with the driven crank 24 and the sliding block 26. The sliding block 26 is slidably mounted on the support 21, and a sliding groove can be formed in the support 21 so that the sliding block 26 slides, or the support 21 comprises a sliding rail on which the sliding block 26 can slide. As shown in fig. 2, the grip 3 is fixedly mounted on the slider 26. The first driving member 4 is capable of driving the driving crank 22 to rotate about the hinge axis of the bracket 21 and the driving crank 22.
When the inertial picker provided by the basic embodiment is used, a picker firstly holds the operating rod 1, so that the grip 3 at the upper end of the operating rod 1 is close to the branches of a fruit tree, the grip 3 is controlled to grip the branches of the fruit tree, and then the first driving piece 4 is controlled to drive the grip 3 to reciprocate through the transmission device 2. As shown in fig. 5, since the driving crank 22, the side link 23, the driven crank 24 and the bracket 21 of the transmission device 2 form a double-crank mechanism, when the first driving member 4 drives the driving crank 22 to rotate at constant speed around the hinge shaft of the bracket 21 and the driving crank 22, the end part of the driving crank 22 drives the driven crank 24 to rotate at variable speed around the hinge shaft of the driven crank 24 and the bracket 21 through the side link 23, and the connecting rod 25 is hinged on the driven crank 24, so that the driven crank 24 drives the connecting rod 25 to perform variable speed motion, and the connecting rod 25 is hinged with the sliding block 26, so that the sliding block 26 obtains acceleration and performs reciprocating linear motion on the bracket 21. Because the driven crank 24 has a pole included angle in the rotating process, the rapid return characteristic is realized, so that fruits on branches caught by the grippers 3 connected with the sliding block 26 shake due to inertia, and the fruits are separated from the branches.
In this application, the first driving member 4 may be mounted at any position of the operating rod 1, preferably, the first driving member 4 is mounted at the lower end of the operating rod 1, that is, the first driving member 4 and the gripper 3 are respectively located at the upper and lower ends of the operating rod 1, so that the convenience of operation of the inertial picker is improved.
Specifically, the operation lever 1 includes a main lever having a tubular shape and a transmission lever (not shown in the figure) rotatably mounted in the main lever, which can be rotatably mounted in the main lever by a bearing. The first driving piece 4 is fixedly arranged at the lower end of the main rod, and an output shaft of the first driving piece 4 is in transmission connection with the lower end of the transmission rod, namely, the first driving piece 4 can drive the transmission rod to rotate. The support 21 is fixedly arranged at the upper end of the main rod, the upper end of the transmission rod is connected with the driving crank 22, and when the transmission rod rotates, the driving crank 22 can be driven to rotate around the hinge shaft of the support 21 and the driving crank 22.
When the output shaft of the first driving member 4 in the above embodiment rotates, the driving rod can be driven to rotate in the main rod, and the upper end of the driving rod is connected with the driving crank 22, so that the driving crank 22 is driven to rotate, and the grip 3 can be driven to reciprocate.
On the basis of the above embodiment, the transmission 2 further comprises a first bevel gear and a transmission shaft in order to make the inertial picker more stable in operation. The drive rod is connected to the drive crank 22 via the second bevel gear, the first bevel gear and the drive shaft. The driving crank 22 is connected with the bracket 21 through a transmission shaft. The transmission shaft is rotatably installed on the support 21 through a bearing, one end of the transmission shaft is fixed with the first bevel gear, the upper end of the transmission rod is fixed with the second bevel gear, the first bevel gear is meshed with the second bevel gear, and the other end of the transmission shaft is vertically and fixedly connected with the driving crank 22. Thus, when the drive rod drives the drive shaft in rotation, the drive crank 22 may rotate about the axis of the drive shaft (i.e., the axis of articulation of the drive crank with the bracket).
In order to avoid damage to the first driving member 4 caused by improper positions of the branches grasped by the grasping arms 3 when the picking operator operates the inertial picker, it is preferable that the output shaft of the first driving member 4 is in driving connection with the lower end of the transmission rod through a centrifugal friction clutch. The centrifugal friction clutch transmits torque by friction force, and the basic structure of the centrifugal friction clutch consists of three elements: a driving part, a centrifugal body and a driven part. The centrifugal body is slidingly arranged on the driving piece, and the driving piece is driven by the prime mover (the first driving piece) to rotate and accelerate so as to throw out the driving piece radially. When the driving part reaches a specified angular speed, the thrown centrifugal body is tightly pressed with the inner wall of the driven part, and the centrifugal body is forced to enter a motion state by friction force to transmit torque.

The engine is simple to operate, economical and durable, strong in power, continuous and stable, low in oil consumption and free of cylinder pulling.
For convenient operation, an accelerator handle is fixedly arranged on the operating rod 1, and a pull wire of the accelerator handle is connected with a throttle valve of the engine. The throttle handle is an auxiliary mechanism for controlling the rotation speed of the engine by hands. The throttle handle is of an integrated design of a handle and a switch, is convenient to use, comfortable in holding feeling, durable and solid.
In the present application, preferably, the operating lever 1 is mounted with a harness. When the inertial picker is used, a picker can carry the inertial picker by the braces, so that the inertial picker can be conveniently used. Further preferably, a handle for manipulating the operation lever 1 is mounted on the operation lever 1. Because the inertial picker is flexibly hung on the body of a picker through the braces, the position of the grip 3 at the upper end of the operating rod 1 can be conveniently adjusted through the handle under the condition that the body of the picker is not moved by installing the handle on the operating rod.
