Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a reversing relay tree shaker. Background Art

[0002] Fruit picking machinery is mainly divided into three types: portable, self-propelled and external drive. Portable picking machinery includes handheld, side-mounted and backpack types, all of which are loaded and operated by a single person. They have disadvantages such as low power of the power device, poor operating efficiency, low picking height, and high labor intensity. The biggest problem with self-propelled picking machinery is that it is expensive and has a single function, so it is difficult to promote and use it on a large scale at this stage. External drive picking machinery uses widely used tractors as power sources and working platforms, which greatly reduces the cost and is convenient and flexible in practical applications, making it more suitable for the actual national conditions at this stage. For external drive picking machinery, the problems that need to be solved urgently include: how to achieve single-person independent operation of tractors and picking machinery, how to achieve convenient and reliable rigid push-pull vibration, and how to achieve efficient picking of large fruit trees.

[0030] In this embodiment, the input part 5 is an internal hexagonal piece, the input shaft 7 is a spline shaft, and the output shaft 9 is an external hexagonal shaft. The input part 5 and the output shaft 9 can also adopt internal / external thread pairs, internal / external spline pairs or flanges to meet different connection requirements. The input shaft 7 is nested and connected with the power output shaft of the tractor through a universal joint cross bearing transmission assembly. The power output shaft of the tractor is horizontally arranged, and the power output direction is converted by a commutator, and the torque is transmitted by a deflection relay mechanism, which finally realizes the upward lifting and vertical output of the external power. In terms of the specific selection of tractor models, the type, horsepower and size of the tractor can be flexibly selected according to the type and size of the fruit trees and combined with the terrain. The fuselage 1 can be connected to the tractor by three-point suspension or four-point hooking.

[0031] In this embodiment, the output part 6 is provided with an eccentric member 11, the central axis of the eccentric member 11 is parallel to the rotation center line of the input part 5, and the eccentric member 11 is provided with a threaded hole 12.

The eccentricity of the eccentric member 11 can be designed as required to achieve the optimal performance requirements of the motion stroke, lever arm or output torque. When a larger motion stroke is required, the eccentricity can be designed to be increased; when a larger output torque is required, the eccentricity can be designed to be reduced.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that: Figure 2 , Figure 4 and Figure 7As shown, in this embodiment, the deflection relay mechanism 3 further includes a housing 14 and a first bearing 15, the first bearing 15 is mounted on the housing 14, the housing 14 is provided with a mounting hole 16, the housing 14 is fixed to the fuselage 1 by bolts and nuts using the mounting hole 16, and the input part 5 is nested and connected with the first bearing 15. The first bearing 15 can adopt a single or multiple deep groove ball bearings, cylindrical roller bearings or tapered roller bearings to meet different load conditions.

[0038] In this embodiment, a transmission member 17 is provided between the input part 5 and the output shaft 9, one end of the transmission member 17 is an external hexagonal member and is nested and connected with the input part 5, and the other end of the transmission member 17 is an internal hexagonal member and is nested and connected with the output shaft 9. The power from the commutator 2 can be extended and transmitted to the yaw relay mechanism 3 through the transmission member 17, thereby improving the working height. The two ends of the transmission member 17 can also adopt matching internal / external thread pairs, internal / external spline pairs or flanges according to the types of the input part 5 and the output shaft 9.

[0039] In this embodiment, one end of the transmission mechanism is connected to a quick connector 20, a second bearing 21 is provided inside the quick connector 20, the second bearing 21 is installed on the quick connector 20, the quick connector 20 is provided with a second connection hole 22, the quick connector 20 uses the second bearing 21 and is rotatably connected with the threaded hole 12 or the eccentric hole 13 through a bolt, and the transmission mechanism 4 and the quick connector 20 respectively use the first connection hole 18 and the second connection hole 22 and are nested and connected through a pin. The second bearing 21 can use a single or multiple deep groove ball bearings, cylindrical roller bearings or tapered roller bearings to meet different load conditions. The application of the quick connector 20 can facilitate the disassembly and assembly of the transmission mechanism 4, and its more important significance is to play a force buffering role, thereby reducing the occurrence of failures.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 2 is that: Figure 3 and Figure 5 As shown, the output part 6 is provided with an eccentric hole 13, the central axis of the eccentric hole 13 is parallel to the rotation center line of the input part 5, and the eccentric hole 13 is a threaded hole. The eccentric hole 13 produces an eccentric effect during revolution, and does not use a guide limit mechanism, so wide-angle operation can be achieved on the revolution plane without the aid of an adjustment device. In this embodiment, the output part 6 is provided with three eccentric holes 13, and the eccentricities of the three eccentric holes 13 are different. When a larger motion stroke is required, an eccentric hole 13 with a larger eccentricity can be selected; when a larger output torque is required, an eccentric hole 13 with a smaller eccentricity can be selected.

[0042] In this embodiment, if the fruit trees with large diameters are to be picked, the force position acting on the fruit trees can be moved upward to greatly reduce the workload. The yaw relay mechanism 3 can be fixed at the highest position of the fuselage 1, and the transmission member 17 can be lengthened to connect the commutator 2 and the yaw relay mechanism 3, so that the trunk of the fruit tree can be pushed and pulled at a higher position from the ground to achieve vibration fruit dropping.

[0043] The implementation principle of this embodiment is as follows: first, when the external drive device 8 is started, its power will be transmitted to the input shaft 7 of the commutator 2 through the universal joint cross bearing transmission assembly. The input shaft 7 is a spline design. The universal joint cross bearing transmission assembly can allow a certain axial / radial movement and angle adjustment while transmitting torque, thereby reducing damage to the shaft and bearings; after the power passes through the commutator 2, the output shaft 9 transmits the power with changed direction to the input part 5 of the eccentric relay mechanism 3; the eccentric relay mechanism 3 has an output part 6, which is equipped with an eccentric piece 11 or an eccentric hole 13. When the input part 5 rotates, the output part 6 also makes a circular motion with the rotation center of the input part 5 as the center due to the eccentric design, so that the transmission While rotating, the guide mechanism 4 can also move in a predetermined offset mode to produce the required swinging motion; one end of the guide mechanism 4 is rotatably connected to the output part 6 of the eccentric relay mechanism 3 through a quick connector 20, and the other end of the guide mechanism 4 is connected to the working fruit tree 10 through an F-type clamp 19. When the guide mechanism 4 moves in a circle with the output part 6 of the eccentric relay mechanism 3, it will drive the fruit tree to push and pull and swing to help the fruit fall off; by adjusting the threaded hole 12 or the eccentric hole 13 on the eccentric member 11, the operator can adjust the intensity and amplitude of the swing according to the size of different fruit trees and the needs of shaking the tree; the hydraulic cylinder 25 can provide lateral pulling force and assist the movement of the guide mechanism 4 through the action of the piston rod 26. At the same time, the first lifting ring 23, the first soft rope 24, the second lifting ring 27 and the second soft rope 28 installed on the fuselage 1 and the guide mechanism help to reduce the useless vibration and swing of the entire tree shaker during operation.
