Description

Technical Field

[0001] The invention relates to the technical field of tea harvesting, in particular to an intelligent tea harvester for use in hilly and mountainous environments. Background Art

[0002] In spring and autumn, the young leaves of tea trees can be picked to make tea, the seeds can be used to extract oil, and the trunks are fine and can be used for carving. Tea is rich in various nutrients and has special medical and health functions. In addition to lowering cholesterol and preventing atherosclerosis, it also has a good preventive effect on radiation, cancer, anemia and other diseases.

[0003] The existing Chinese patent CN115735567A discloses a tea harvester for hilly and mountainous environments. The machine is driven by a hydraulic motor and the crawler chassis rotates by itself, and relies on sliding friction to adjust the distance between the two crawler chassis according to the width of the tea ridge before harvesting large quantities of tea. However, during the use of the above device, when the hydraulic motor changes the distance between the two crawler chassis, the moving direction of the crawler chassis is perpendicular to the rotation direction of the crawler chassis. Therefore, when adjusting the distance between the two crawler chassis, it is not only easy to cause the machine to become unbalanced and increase the risk of rollover, but also in the process of adjusting the distance between the crawler chassis, the friction resistance between the crawler and the ground is large, which is also easy to cause the crawler on the crawler chassis to deviate, affecting the normal rotation of the subsequent crawler.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1-Figure 4The intelligent tea harvester for hilly and mountainous environments shown in the figure includes two symmetrically distributed crawler chassis 1, and protective covers 2 are installed on the outer sides of the two crawler chassis 1. A support frame 3 is fixedly installed at the center of the upper end of the protective cover 2. A picking platform 4 and an embedded rod 6 are respectively installed between the two support frames 3, and the embedded rod 6 is located on the upper side of the picking platform 4. The two ends of the embedded rod 6 are respectively fixedly connected to the two support frames 3, and also include an embedded rod 6 movably embedded in the outer side of the picking platform 4, and the connection between the embedded rod 6 and the picking platform 4 is a plug-in connection, and the end of the embedded rod 6 away from the picking platform 4 is fixedly connected to the support frame 3; a support mechanism is used to support the crawler chassis 1 so that the crawler chassis 1 is separated from the ground, and the support mechanism is installed on the outer side of the protective cover 2; a drive component is used to drive the support mechanism to rotate and reduce the ground occupied by the support mechanism, and the drive component is installed between the protective cover 2 and the support mechanism.

[0032] The supporting mechanism includes a supporting frame 7 installed on the upper side of the protective cover 2, and the supporting frame 7 is movably sleeved on the outer side of the supporting frame 3. Four lifting columns 8 distributed in a rectangular array are fixedly installed on the lower end of the supporting frame 7. The lifting columns 8 are used to drive the supporting frame 7 to move up and down. A fixing seat 9 is fixedly sleeved on the outer side of the lifting column 8, and the connection between the fixing seat 9 and the protective cover 2 is a fixed connection.

[0033] A plurality of rollers 10 equidistantly distributed are mounted on the outside of the protective cover 2, a support cover 11 is movably sleeved on the outside of the roller 10, and the roller 10 is rotatably connected to the support cover 11 through an axle pin 12, an anti-slip pattern is provided on the outside of the roller 10, a support rod 13 is fixedly embedded at the center of the upper end of the support cover 11, a support column 14 is mounted on the upper end of the support rod 13, and the support rod 13 is rotatably connected to the support column 14 through a bearing 15.

[0034] Working principle: Two crawler chassis 1 are located on both sides of the tea tree ridge. When the two crawler chassis 1 drive the picking platform 4 to move, the mechanical gripper installed on the picking platform 4 picks the tender buds of the tea tree;

[0035] When the device needs to adjust the width according to the ridge of the tea trees, the personnel controls the lifting column 8 in the support mechanism to operate, and the lifting column 8 drives the support frame 7 and the multiple rollers 10 to move downward. After the multiple rollers 10 move downward and contact the ground, the crawler chassis 1 is separated from the ground under the support of the multiple rollers 10, so that the multiple rollers 10 support the crawler chassis 1 (as shown in the attached manual). Figure 2As shown), the personnel then controls the telescopic rod 5 to operate, and the telescopic rod 5 adjusts the distance between the two crawler chassis 1 according to the width of the tea tree ridge, which can avoid direct contact and friction between the crawler tracks in the crawler chassis 1 and the ground, thereby not only enhancing the stability of the equipment during the adjustment of the distance between the crawler chassis 1, but also preventing the crawler tracks from shifting due to the contact and movement between the crawler chassis 1 and the ground. When the distance between the two crawler chassis 1 is adjusted according to the width of the tea tree ridge, the lifting column 8 operates to drive the multiple rollers 10 to move and reset.

[0036] Example 2: Please refer to Figure 2 , Figure 7 This embodiment further explains the first embodiment. The driving assembly includes a sleeve 16 movably sleeved on the outside of the support rod 13, and the connection between the sleeve 16 and the protective cover 2 is a fixed connection. The inner wall diameter of the sleeve 16 is larger than the diameter of the support rod 13. An oblique arc groove 17 is provided inside the sleeve 16. Vertical portions 18 are respectively provided at both ends of the oblique arc groove 17, and the oblique arc groove 17 and the vertical portion 18 are connected to each other.

[0037] A pin 19 is fixedly embedded in the outer side of the support rod 13 corresponding to the inner side of the sleeve 16, and a hemispherical portion 2 is provided at one end of the pin 19 close to the inner wall of the sleeve 16. The pin 19 is in sliding contact with the sleeve 16 through the oblique arc groove 17 and the vertical portion 18. The oblique arc groove 17 can drive the support rod 13 to deflect 90° through the pin 19. Two symmetrically distributed positioning components are installed inside the support column 14 corresponding to the outer side of the support rod 13.

[0038] The positioning assembly includes a pin rod 20 that can move left and right inside the support column 14. A hemispherical portion 21 is provided at one end of the pin rod 20 close to the support rod 13. A washer 22 is fixedly sleeved on the outer side of the pin rod 20. The washer 22 is used to prevent the pin rod 20 from detaching from the support column 14. A spring 23 is movably sleeved on the outer side of the pin rod 20, and the two ends of the spring 23 are movably abutted against the support column 14 and the washer 22 respectively.

[0039] Four hemispherical slots 24 equidistantly distributed on the outer side of the support rod 13 are provided at the corresponding positioning assembly, and the hemispherical portion 1 21 is movably connected to the support rod 13 through the hemispherical slots 24. Two symmetrically distributed limit blocks 25 are fixedly installed on the side wall of the protective cover 2 corresponding to the outer side of the support rod 13. The limit blocks 25 are used to prevent the pin rod 20 from moving inside the support column 14, and the connection between the pin rod 20 and the limit block 25 is a movable abutment.

[0040] Two rows of limit assemblies are installed on the outside of the protective cover 2, and the number of limit assemblies in each row is equal to the roller 10. The limit assemblies include a limit baffle 26 movably embedded on the outside of the protective cover 2. The limit baffle 26 is used to prevent the support column 14 from moving upward. A limit rotation groove 27 is provided on the outside of the protective cover 2 corresponding to the limit baffle 26, and semicircular strips 28 are provided at both ends of the limit baffle 26.

[0041] In this embodiment, when the lifting column 8 drives the support rod 13 to move downward, the pin rod 19 on the outer side of the support rod 13 is located in the vertical portion 18 at the upper end of the oblique arc groove 17. In the process of the pin rod 19 moving downward with the support rod 13, the sleeve 16 drives the support rod 13 and the roller 10 to rotate 90° (the roller 10 is in contact with the ground at this time) through the oblique arc groove 17 and the pin rod 19, so that the rotation direction of the roller 10 is perpendicular to the rotation direction of the crawler chassis 1. In the process of the support rod 13 rotating, the hemispherical portion 21 of the pin rod 20 is pressed against the spring 23. Driven by the compression elastic force, the pin rod 20 is embedded in the hemispherical slot 24 on the outer side of the support rod 13 to position the support rod 13. When the pin rod 20 moves with the support column 14 to the limit stopper 25, the crawler chassis 1 is separated from the ground, and the multiple rollers 10 support the crawler chassis 1, so that when the multiple rollers 10 roll, the pin rod 20 cannot move inside the support column 14 under the blockage of the limit stopper 25, so that the pin rod 20 can position the support rod 13 and prevent the moving direction of the roller 10 from changing during the rolling process;

[0042] When the crawler chassis 1 contacts the ground and the roller 10 moves back to its original position, the rotation direction of the roller 10 is the same as that of the crawler chassis 1, thereby effectively preventing multiple rollers 10 from protruding and being hit, and reducing the size of the device.

[0043] Example 3: Please refer to Figure 3-Figure 6 , Figure 8 , Fig. 9 This embodiment further explains the second embodiment. The limit baffle 26 is rotatably connected to the protective cover 2 through a limit rotation groove 1 27 and a positioning shaft 29. Two symmetrically distributed coil springs 30 are fixedly sleeved on the outer side of the positioning shaft 29, and the outer ends of the coil springs 30 are fixedly connected to the protective cover 2. A limit rotation groove 2 31 is provided on the side of the support column 14 close to the protective cover 2. A thickening block 33 is fixedly installed on the upper end of the protective cover 2 corresponding to the upper side of the coil spring 30. The thickening block 33 is used to thicken the protective cover 2 where the coil spring 30 is installed.

[0044] The semicircular strip portion 28 at the lower end of the limit baffle 26 is movably abutted against the support column 14 through the limit rotation groove 2 31, and an electromagnetic suction block 32 is fixedly embedded in the support column 14 corresponding to the limit rotation groove 2 31. The electromagnetic suction block 32 is used to drive the limit baffle 26 to rotate, and the connection method between the electromagnetic suction block 32 and the limit baffle 26 is active magnetic suction, and the circuits of multiple electromagnetic suction blocks 32 are connected in series with the circuits of the telescopic rod 5.

[0045] In this embodiment: after the support mechanism supports the crawler chassis 1 to leave the ground, the personnel controls the telescopic rod 5 to operate. Since the circuit of the telescopic rod 5 is connected in series with the circuits of multiple electromagnetic suction blocks 32, when the telescopic rod 5 is operating, the electromagnetic suction block 32 is energized, and the electromagnetic suction block 32 is energized to adsorb the limit baffle 26, so that the semicircular strip portion 28 at the lower end of the limit baffle 26 rotates into the second limit rotation groove 31. At this time, the support column 14 is blocked by the limit baffle 26 and cannot move up the outside of the protective cover 2. Therefore, in the process of adjusting the distance between the two crawler chassis 1 by the roller 10, the support column 14 can be blocked by the limit baffle 26, which can effectively reduce the pressure on the lifting column 8 and avoid bumps that affect the service life of the lifting column 8;

[0046] When the spacing between the two crawler chassis 1 is adjusted and the equipment is stable as a whole, the personnel control the telescopic rod 5 and the electromagnetic suction block 32 to cut off the power. After the electromagnetic suction block 32 is powered off, its suction force disappears. At this time, the limit baffle 26 will rotate into the limit rotation groove 27 driven by the coil spring 30, releasing the obstruction to the support column 14, so that the multiple rollers 10 can move back and reset under the drive of the lifting column 8.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
