Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a durable fruit picking device. Background Art

[0002] Nowadays, people's pursuit of quality of life has made their diet more and more refined. In particular, fruits that help speed up the body's metabolism have become an indispensable food in people's daily life. In order to improve the quality of fruit products, fruit orchards usually plant fruit trees in suitable plots to facilitate management and harvesting.

[0003] When the fruit is ripe, a large number of workers are needed to pick the fruit because the time it takes to harvest and put it on the market is short. However, the fruits on the trees are of different heights, which makes picking difficult, making manual picking inefficient. As a result, fruit picking devices have appeared on the market, which use hooks or scissors on the device to pick the fruit, greatly improving the picking efficiency. However, the traditional fruit picking device only has ordinary radial bearings to withstand the radial force when the motor is driven. The axial force generated by the user when picking the fruit will cause the radial bearings and other components in the fruit picking device to wear more severely, greatly shortening the life of the fruit picking device and increasing the production cost of the fruit.

The elastic member 6 is used to limit the first connecting tube 2 01 and the second connecting tube 202 for relative rotation, the transmission shaft 3 is arranged in the first connecting tube 201, and a bent shaft 7 is arranged on the mounting tube 2, one end of the bent shaft 7 is connected to the transmission shaft 3, and the other end of the bent shaft 7 is connected in the second connecting tube 202, a second bearing assembly 8 and a first bearing 9 are arranged in the second connecting tube 202, the second bearing assembly 8 and the first bearing 9 are connected to the bent shaft 7, a first bearing assembly 10 is arranged in the first connecting tube 201, the first bearing assembly 10 is connected to the transmission shaft 3, the picking device 11 is connected to the end of the second connecting tube 202, and the first bearing 9 is a tapered bearing or a thrust bearing. The user turns on the power supply 4 to start the motor 5, and the driving force is transmitted to the transmission shaft 3 through the output end of the motor 5. The transmission shaft 3 drives the first bearing assembly 10 and the bent shaft 7 to move, and the bent shaft 7 drives the second bearing assembly 8 and the first bearing 9 in the second connecting tube 202 to move, so that the second connecting tube 202 and the picking device 11 shake under the drive of the bent shaft 7. The user can use the shaking picking device 11 to harvest the fruits on the fruit trees, making the fruit picking operation very convenient. During the harvesting operation, an axial force will be generated on the picking device 11 and the second connecting tube 202. At this time, the first bearing 9 absorbs and withstands the generated axial force to prevent the axial force from affecting the operation of other components of the fruit picking device, and prevent the wear between the components due to the axial force from being aggravated, thereby greatly increasing the service life of the fruit picking device.

[0042] Preferably, the picking device 11 is a picking hook.

[0043] Preferably, the first bearing 9 is a thrust bearing.

[0044] See Figure 2 、 3 As shown in Figures 4 and 9, the end of the bent shaft 7 near the picking device 11 is connected to a clamping block 12, and a gasket 30 is abutted between the first bearing 9 and the second bearing assembly 8. The two side surfaces of the first bearing 9 abut against the clamping block 12 and the gasket 30, respectively.

[0045] See Figures 1 to 4 As shown, the second bearing assembly 8 includes a first radial bearing 801 and a second radial bearing 802, both of which abut against the second connecting tube 202. The installation of the first and second radial bearings 801, 802 in the second connecting tube 202 significantly increases the system redundancy of the fruit picking device. Even in the event of damage or jamming of the first or second radial bearing 801, 802, the picking device 11 can still operate normally, greatly improving the operational stability of the fruit picking device.

At the same time, the stable movement of the second connecting tube 202 also improves the operating efficiency of the picking device 11.

[0047] See Figure 2 、 3 As shown in Figures 4, 5, and 9, a mounting barrel 16 is connected to the end of the transmission shaft 3, and the mounting barrel 16 and the bent shaft 7 are detachably connected. The detachable connection between the mounting barrel 16 and the bent shaft 7 facilitates the disassembly and assembly of the bent shaft 7 on the first connecting tube 201 and the second connecting tube 202, facilitating the timely replacement of a damaged bent shaft 7 by the user. This makes the maintenance of the fruit picking device very convenient and quick, greatly reducing the maintenance and use costs of the fruit picking device.

[0048] See Figure 2 、 3As shown in Figures 4, 5, and 9, the bent shaft 7 includes an integrally formed threaded column 701 and a bent rod 702.

The two side surfaces of the fourth radial bearing 102 are respectively in contact with the annular step surface 18 and the third radial bearing 101. The first bearing assembly 10 includes a third radial bearing 101 and a fourth radial bearing 102, so that the fruit picking device can still operate normally even when the third radial bearing 101 or the fourth radial bearing 102 is damaged or stuck, thereby improving the working stability of the fruit picking device; and the two side surfaces of the third radial bearing 101 are respectively abutted against the third shoulder 19 and the fourth radial bearing 102, and the two side surfaces of the fourth radial bearing 102 are respectively abutted against the annular step surface 18 and the third radial bearing 101, so that the third radial bearing 101 and the fourth radial bearing 102 are installed very firmly in the first connecting tube 201, and the overall structure is more compact.

[0053] Preferably, the control unit 29 is a single chip microcomputer.

[0054] See Figure 3 、 4 As shown in Figures 9 and 9, a first shoulder 13 is provided on the curved shaft 7 for limiting the relative position of the first bearing 9. The provision of the first bearing 9 ensures a relatively stable position of the first bearing 9 on the curved shaft 7, preventing the first bearing 9 from loosening during operation of the fruit picking device 11, causing the first bearing 9 to deviate significantly from the curved shaft 7 or fall off the curved shaft 7.

[0055] When the present invention is in use, the user presses the button 27 to turn on the power supply 4, so that the motor 5 starts working, and the motor 5 drives the reduction gear set 26 to rotate. The output end of the reduction gear set 26 transmits the driving force to the transmission shaft 3, and the transmission shaft 3 drives the first bearing assembly 10 and the bent shaft 7 to move. The bent shaft 7 drives the second bearing assembly 8 and the first bearing 9 in the second connecting tube 202 to move, so that the second connecting tube 202 and the picking device 11 shake under the drive of the bent shaft 7. At this time, the user can use the shaking picking device 11 to harvest fruits from the fruit trees, making the fruit picking operation very convenient.
