Description

Technical Field

[0001] The utility model relates to the field of Torreya grandis picking equipment, in particular to a variable force type Torreya grandis vibration harvester. Background Art

[0002] Torreya grandis 'Merrillii' Hu, also known as fine torreya and sheep-horn torreya, is a highly cultivated species of Torreya grandis in the Taxaceae family. It is a rare and valuable dried fruit tree species unique to China. It is robust and prefers warm, humid climates. Young trees prefer shade, are intolerant to heat and waterlogging, and are relatively cold-resistant and resistant to infertility. Torreya seeds are highly nutritious and are a valuable traditional Chinese medicinal material. Harvesting Torreya grandis is a costly component of the Torreya grandis industry, and currently, mature machinery and equipment are lacking to support the industry's development.

[0003] In recent years, the market share of Torreya grandis has gradually expanded, and the output has increased year by year. The existing Torreya grandis picking operation mainly relies on manual labor, in which the high labor cost and low picking efficiency have seriously restricted the development of the Torreya grandis industry. Older Torreya grandis trees need to use tools such as centipede ladders to climb branches to complete the picking of Torreya grandis, which poses a safety hazard to practitioners at work. The different maturity of Torreya grandis fruits leads to premature harvesting, which will affect the taste and quality of the fruit. Chinese patent CN202220104102.8 provides a picking device for Torreya grandis, but this type of machine picking cannot cause damage to the plants without fruit falling, and the force cannot be adjusted according to actual needs.

DETAILED DESCRIPTION

[0023] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] The variable force torreya grandis vibration harvester includes a mounting base 1, a clamping mechanism 2 and a vibration mechanism 3; the clamping mechanism 2 and the vibration mechanism 3 are installed on the mounting base 1; in this embodiment, the mounting base 1 is a shell structure, and the vibration structure is arranged inside the mounting base 1, and transmits vibration to the mounting base 1 during its movement.

[0026] The clamping mechanism 2 includes clamping arms 4, and a clamping opening 5 that can be opened or closed is formed between the clamping arms 4. The clamping opening 5 is used to clamp or release the branches and leaves of Torreya grandis. The clamping mechanism 2 clamps the branches and leaves of Torreya grandis and then vibrates to shake the Torreya grandis off the branches.

[0027] The vibration mechanism 3 comprises a motor 6 and a crank 7 driven by the motor 6. When the motor 6 rotates the crank 7, it applies a vibration force to the clamping arm 4 through the mounting base 1. Because the center of gravity of the crank 7 can shift back and forth during movement, it causes the mounting base 1 to shake or vibrate. This vibration is then transmitted to the clamped Torreya grandis branch through the clamping mechanism 2. When the excitation force generated by the vibration mechanism 3 exceeds the binding force of the fruit stem, the Torreya grandis falls.

[0028] In this embodiment, a counterweight 8 is also provided on the crank 7. In this embodiment, the counterweight 8 is detachably mounted on the crank 7. In order to be able to adjust the excitation force generated by the crank 7 mechanism in multiple ways, the crank 7 is provided with multiple mounting points 9 for mounting the counterweight 8.

[0029] In this embodiment, the distances between the mounting points 9 and the axis of the rotating portion of the crank 7 are not equal.

[0030] In this embodiment, the mounting base 1 includes a housing portion 10, with a fixing base 11 disposed in the middle of the housing portion 10. The crank 7 includes a rotating shaft portion 12 and an arm portion 13 connected to the rotating shaft portion 12. The arm portion 13 is located in a cavity within the housing portion 10. The rotating shaft portion 12 is mounted on the fixing base 11 via a bearing unit. The rotating shaft portion 12 is connected to the output terminal of the motor 6. The fixing base 11 provides a stable force for the crank 7, preventing shaking at the connection, which could cause jamming or shorten its lifespan.

[0031] In this embodiment, the output end of the motor 6 is connected to the rotating shaft portion 12 through a coupling 20 .

[0032] In this embodiment, the mounting base 1 further includes a second housing portion 14, which is located below the first housing portion 10. The motor 6 is mounted within the second housing portion 14. The second housing portion 14 and the first housing portion 10 are fixedly connected. Specifically, in this embodiment, the second housing portion 14 and the first housing portion 10 are integrally formed, specifically, a cavity structure consisting of two parts.

[0033] To further describe the structure of the clamping mechanism 2, the mounting base 1 also includes an upper frame 15, and the clamping mechanism 2 also includes a telescopic mechanism 16. One end of the telescopic mechanism 16 is hinged to the mounting base 1, and the other end is hinged to the clamping arm 4. The middle portion of the clamping arm 4 is rotatably connected to the frame 15 via a pivot 19 provided on the frame 15. During the telescopic mechanism 16's extension and retraction, the clamping arm 4 is driven to rotate about the pivot 19 to achieve clamping or loosening. The clamping arm 4 is divided into two parts by the pivot 19, wherein the free end portion is divided into an arc shape. The two free end portions of this shape form a clamping area that can be used to clamp branches. In this embodiment, the telescopic mechanism 16 uses a gas rod to achieve this function.

[0034] Since the Torreya grandis tree is relatively tall, a gripping rod 17 is mounted on the lower end of the mounting base 1. The length of the gripping rod 17 can be selected as needed.

[0035] The bottom of the mounting base 1 is provided with a shock absorbing block 18, and the gripping rod 17 is mounted on the shock absorbing block 18. The shock absorbing block 18 can effectively reduce the transmission of external force through deformation and consume vibration energy through the damping effect.

[0036] Working principle:

[0037] When the equipment processing starts, the power of the equipment is started, the Torreya grandis vibration harvester is manually held, the clamping head is controlled to open by the button, and the target branch is found. Then, the clamping head is closed by manual calibration to clamp the branch. The switch is turned on to rotate the crank 7 through the motor 6. The reciprocating motion of the crank 7 and the counterweight 8 generates an exciting force, which forces the Torreya grandis branches to vibrate and transmits the exciting force to the junction of the Torreya grandis fruit stalks. When the exciting force is greater than the binding force of the fruit stalks, the Torreya grandis falls, completing the Torreya grandis fruit harvesting operation.

[0038] Example 2

[0039] The difference from embodiment 1 is that the telescopic mechanism 16 is replaced by an electric cylinder.

[0040] Example 3

[0041] The difference from embodiment 1 is that the shock absorbing block 18 is a rubber block.
