[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0028] like Figure 1 and Figure 2 As shown, the adaptive fruit harvesting device that avoids rigid contact includes a brush unit 2 and a vibration unit 1, which is detachably connected to the brush unit 2.
[0029] like Figures 3 to 6 As shown, the combing unit 2 includes a plate-shaped combing base plate 21. The inner wall of the combing base plate 21 is provided with several parallel base plate guide rails 211. Several movable combing rod assemblies 20 are arranged between the base plate guide rails 211. The left and right edges of the inner sidewall of the combing base plate 21 are each provided with a grooved guide rail 28. A movable grooved plate 26 is arranged between the grooved guide rails 28. Several through-type adjusting grooves 261 are provided on the grooved plate 26. The adjusting grooves 261 cooperate with the combing rod assemblies 20 and adjust the spacing of the combing rod assemblies 20. Several push plate joints 25 and push rod brackets 24 are provided on the distal sidewall of the grooved plate 26. A pair of fixed seats 22 are provided on the outer wall of the combing base plate 21. A hydraulic cylinder 23 is provided between the fixed seats 22. The movable shaft of the hydraulic cylinder 23 is fixedly connected to the push rod bracket 24. Several first connecting screw holes 210 are provided in the middle of the outer wall of the combing base plate 21.
[0030] like Figures 7 to 9 As shown, the comb bar assembly 20 includes a long strip-shaped main horizontal bar 29. The upper side wall of the main horizontal bar 29 is provided with a limiting rod 291 at its end. The upper side wall of the main horizontal bar 29 is provided with several detachable comb bases 208. The comb base 208 is provided with a rubber base 206. The rubber base 206 is provided with a rod seat 203. The rod seat 203 is provided with a comb bar 201. The top of the rod seat 203 is provided with a top nut 202. The tail shaft section of the comb bar 201 is fitted with a spring 207. The lower side wall of the main horizontal bar 29 is provided with several sliding seats 292. The sliding seats 292 cooperate with the base plate guide rail 211.
[0031] One end of the spring 207 abuts against the shoulder of the comb bar 201, and the other end of the spring 207 abuts against the shoulder of the hole in the bar body seat 203. The bar body seat 203 is installed in the rubber base 206 by an elastic washer 205. The top of the comb base 208 is provided with a bottom nut 204, which constrains the rubber base 206 in the comb base 208.
[0032] It should be noted that the diameter of the tail section of the brush bar 201 is smaller than the diameter of the through hole at the bottom of the bar body seat 203. Under a large axial external force, the brush bar 201 can slide and extend within the bar body seat 203 via the spring 207. The diameter of the inner hole in the middle of the top nut 202 is larger than the diameter of the front section of the brush bar 201, which, without affecting the extension and retraction of the brush bar 201, constrains the brush bar 201 to extend to the left, preventing it from slipping out of the bar body seat 203.
[0033] like Figure 10 and Figure 11 As shown, the vibration unit 1 includes a plate-shaped base 15. A mounting bracket 18 and a motor base 17 are provided on the outer wall of the base 15. A hydraulic motor 171 is mounted on the motor base 17, and a crank wheel 16 is mounted on the output shaft of the hydraulic motor 171. A pair of parallel guide rails 13 are provided on the inner wall of the base 15, and a slidable slide 11 is provided between the guide rails 13. The slide 11 has several second connecting screw holes 111, which are connected to the first connecting screw holes. Hole 210 is connected by screws. The crank wheel 16 is provided with an eccentric shaft 161. The eccentric shaft 161 is provided with a connecting rod 14. The other end of the connecting rod 14 is hinged to the connecting rod 12. The outer wall of the slide block 11 is provided with a pair of sliders 19 and a connecting block 191. The connecting block 191 is provided with a through connecting block hole 192. The slider 19 cooperates with the guide rail 13. The end of the connecting rod 12 passes through the connecting block hole 192 and is fixedly connected to the connecting block 191.
[0034] It should be noted that the mounting bracket 18 can be connected to external mechanical equipment, such as a hydraulic arm 3.
[0035] The working principle of vibration unit 1 is explained below.
[0036] like Figure 10 As shown, when the hydraulic motor 171 starts, the crank wheel 16 drives the connecting rod 14 through the eccentric shaft 161, and the connecting rod 14 drives the connecting block 191. As a result, the slide 11 begins to slide back and forth on the guide rail 13. Since the slide 11 is fixedly connected to the comb base plate 21, the comb base plate 21 begins to vibrate back and forth.
[0037] The working principle of the comb unit 2 is explained below.
[0038] like Figure 13 As shown, when the vibration unit 1 starts working, the brush rod 201 of the brush rod assembly 20 of the brush base plate 21 starts to vibrate and comes into contact with the fruit of the target tree 4, causing the fruit to fall.
[0039] It should be noted that when the brush rod 201 is subjected to a large radial external force, the deformation of the rubber base 206 allows the rod seat 203 to cause the brush rod 201 to swing to a certain extent. In addition, when the brush rod 201 is subjected to a large external force, it can produce a certain amount of extension and oscillation, thereby avoiding rigid contact with the branches and causing damage to the fruit tree, and realizing adaptive brushing vibration.
[0040] When it is necessary to adjust the spacing of the comb bar assembly 20, the hydraulic cylinder 23 can be activated. The hydraulic cylinder 23 drives the push rod frame 24, the push plate joint 25 and the groove plate 26 to move synchronously. Then, the adjusting groove 261 on the groove plate 26 begins to squeeze the limiting rod 291, causing the comb bar assembly 20 to slide along the bottom plate guide rail 211, thereby increasing or decreasing the spacing of the comb bar assembly 20 to adapt to the harvesting needs of different fruit trees and fruit varieties, increasing the adaptability and flexibility of the equipment.
[0041] This adaptive fruit harvesting device, which avoids rigid contact, achieves adaptive extension and oscillation of the comb rod through a hydraulic system and elastic structure design. The comb rod can automatically adjust according to the shape of the fruit tree branches and the distribution of the fruit, effectively reducing the damage to the fruit tree and fruit caused by rigid contact.
[0042] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
