A tracked goji berry harvesting machine

Abstract

This utility model relates to the field of wolfberry harvesting technology, specifically a tracked wolfberry harvesting machine, including a tracked vehicle with a harvesting box. The harvesting box contains two symmetrically arranged vibration components for generating axial and circumferential vibrations. Each vibration component has a first and a second vibration comb for contacting branches and transmitting the vibrations. By setting up a drive component, vibration components, and a guide component, when the vibration comb generates axial vibration, the guide sleeve forces the rotating shaft and rotating sleeve to drive the vibration comb to generate horizontal circumferential vibration, causing the branches and fruits to be subjected to alternating forces in both vertical and horizontal directions simultaneously. This more comprehensively acts on the fruit-stalk junction, improving the thoroughness of shaking off ripe fruit. Simultaneously, the opposite rotation direction of the first and second guide grooves allows the first and second vibration combs to generate opposite circumferential movements, effectively increasing the inertial difference between the fruit and branches, and quickly breaking through the bonding threshold through multi-directional shearing force.

Description

Technical Field

[0001] This utility model relates to the field of goji berry harvesting technology, and in particular to a tracked goji berry harvesting machine. Background Technology

[0002] A goji berry harvester is an agricultural machine specifically designed for harvesting goji berry fruits. It aims to improve harvesting efficiency and reduce labor costs. The machine uses high-frequency vibration (mechanical or pneumatic drive) to generate inertial force on the branches. When the inertial force on the fruit is greater than the binding force of the fruit stalk, the fruit falls off. It is suitable for large-scale plantations.

[0003] The comb-type goji berry harvester disclosed in Chinese Patent Publication No. CN220755574U uses the up-and-down movement of a comb to shake goji berries off branches, preventing them from hitting the inner wall of the collection box and causing damage. However, according to the comb-type goji berry harvester provided by related technologies and existing technologies, the vibrating comb of the existing vibrating harvester can only achieve up-and-down vibration in one direction. Its vibration force transmission path is single and its action dimension is limited, resulting in branches and fruits only producing simple harmonic motion in the vertical direction. This unidirectional vibration mode is difficult to match the anisotropic characteristics of the fruit-stalk bonding force, which easily leads to the problem of incomplete shaking off of ripe fruits, ultimately resulting in low harvesting efficiency and insufficient harvesting rate, which is difficult to meet the actual needs of efficient harvesting. Utility Model Content

The rotating sleeve and the fixed columns are provided with clearance grooves for the fixed columns to move at corresponding positions, and a limiting ring is fixedly provided on the rotating shaft near the top of the rotating sleeve.

[0008] Preferably, the guiding assembly includes a fixing ring fixed to the top of the picking box, a guide sleeve fixedly provided at the top of the fixing ring, a first guide groove provided at the top of the guide sleeve, a second guide groove provided at the bottom of the guide sleeve, the first guide groove and the second guide groove are both spiral and rotate in opposite directions, a first guide post is fixedly provided at the position of the rotating shaft corresponding to the first guide groove, and a second guide post is fixedly provided at the position of the rotating sleeve corresponding to the second guide groove.

[0009] Preferably, the collection assembly includes two conveyors fixed to both sides of the bottom of the picking box, a closure for fruit trees to pass through is installed between the two conveyors, and a collection box is provided at the end of the stroke of each conveyor.

[0010] Preferably, there are multiple first and second vibrating combs, and they are alternately arranged along the axial direction of the rotating shaft.

[0011] Preferably, a sliding rod is fixedly provided on the top of the picking box, and the lifting plate is vertically slidably installed on the top of the picking box via the sliding rod.

[0012] Beneficial effects:

[0013] This tracked goji berry harvester, through the setting of drive components, vibration components, and guide components, when the vibrating comb generates axial vibration, the guide sleeve forces the rotating shaft and rotating sleeve to drive the vibrating comb to generate horizontal circumferential vibration, so that the branches and fruits are subjected to alternating forces in both vertical and horizontal directions, which more comprehensively acts on the fruit-stalk junction, improving the thoroughness of shaking off ripe fruits. At the same time, by utilizing the design of the first and second guide grooves rotating in opposite directions, the first and second vibrating combs generate reverse circumferential motion, effectively increasing the inertial difference between the fruit and the branches, and quickly breaking through the junction threshold through multi-directional shearing force.

[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0026] like Figures 1 to 8 As shown, a tracked goji berry harvester includes a tracked vehicle 1, a harvesting box 2 mounted on the tracked vehicle 1, and two symmetrically arranged vibration components 3 for generating axial and circumferential vibrations inside the harvesting box 2. Each vibration component 3 has a first vibration comb 9 and a second vibration comb 10 for contacting branches and transmitting the vibrations of the vibration component 3. A drive component 5 for forcing the vibration component 3 to vibrate axially is located at the top of the two vibration components 3. Below the drive component 5, each vibration component 3 has a guide component 4 for forcing the vibration component 3 to vibrate circumferentially when vibrating axially. A collection component 6 for collecting fallen fruits is located at the bottom of the harvesting box 2. In use, the tracked vehicle 1 moves the harvesting box 2, allowing the goji berry trees to pass through the inside of the harvesting box 2. During this process, the drive component 5 forces the vibration component 3 to move up and down to generate axial vibration, which in turn drives the first vibration comb 9 and the second vibration comb 10 to generate axial vibration. At the same time, the guide component 4 forces the vibration component 3 to rotate back and forth, which drives the first vibration comb 9 and the second vibration comb 10 to generate circumferential vibration, effectively improving the shaking effect on the goji berry fruit. The shaken-down fruit falls onto the collection component 6 for collection.

[0027] like Figures 2 to 4 As shown, the drive assembly 5 includes a motor 51 fixed to the top of the picking box 2. A crank 52 is fixedly provided at the output end of the motor 51. A rocker arm 53 is hinged to the end of the crank 52 away from the motor 51. A lifting plate 54 is hinged to the end of the rocker arm 53 away from the crank 52. A slide bar 11 is fixedly provided at the top of the picking box 2. The lifting plate 54 is vertically slidably installed on the top of the picking box 2 through the slide bar 11. The motor 51 drives the crank 52 to rotate, and pushes the lifting plate 54 to move up and down along the slide bar 11 through the rocker arm 53.

[0028] like Figures 5 to 7As shown, the vibration assembly 3 includes a rotating shaft 31 rotatably mounted at both ends of the lifting plate 54. The lower end of the rotating shaft 31 extends into the picking box 2. A rotating sleeve 32 is rotatably mounted on the outside of the rotating shaft 31. A support plate 34 is fixedly mounted at the bottom of the rotating shaft 31. Multiple fixed posts 33 are arrayed along the axial direction of the rotating shaft 31. Relief grooves for the fixed posts 33 are provided at positions corresponding to the rotating sleeve 32 and the fixed posts 33. A limiting ring 12 is fixedly mounted on the rotating shaft 31 near the top of the rotating sleeve 32. Multiple first vibrating combs 9 and second vibrating combs 10 are provided, and they are alternately arranged along the axial direction of the rotating shaft 31. The first vibrating comb 9 is fixedly connected to the rotating shaft 31 through the fixed posts 33, and the second vibrating comb 10 is fixedly connected to the rotating shaft 31 through the fixed posts 33. The sleeve 32 is fixedly connected; when the lifting plate 54 moves, it will synchronously drive the rotating shaft 31 to move up and down. At the same time, the rotating sleeve 32 moves up and down synchronously with the rotating shaft 31 under the restriction of the support plate 34 and the limiting ring 12, thereby causing the first vibrating comb 9 and the second vibrating comb 10 to generate axial vibration. During the up and down movement of the rotating shaft 31 and the rotating sleeve 32, the guide component 4 can force the rotating shaft 31 and the rotating sleeve 32 to generate circumferential rotation in opposite directions, so that the first vibrating comb 9 and the second vibrating comb 10 form opposite vibrations in the circumferential direction. Through the combined motion of axial vibration and horizontal circumferential vibration, the branches and fruits are simultaneously subjected to alternating forces in the vertical and horizontal directions, which significantly improves the thoroughness of shaking off ripe fruits.

[0029] like Figures 3 to 8 As shown, the guide assembly 4 includes a fixing ring 41 fixed to the top of the picking box 2. A guide sleeve 42 is fixedly provided on the top of the fixing ring 41. A first guide groove 43 is provided on the top of the guide sleeve 42, and a second guide groove 44 is provided on the bottom of the guide sleeve 42. Both the first guide groove 43 and the second guide groove 44 are spiral-shaped and rotate in opposite directions. A first guide post 7 is fixedly provided on the rotating shaft 31 at the position corresponding to the first guide groove 43, and a second guide post 8 is fixedly provided on the rotating sleeve 32 at the position corresponding to the second guide groove 44. During the up-and-down movement of the rotating shaft 31 and the rotating sleeve 32, the rotating shaft 31 drives the first guide post 7 to slide along the first guide groove 43 and rotates back and forth under the push of the first guide groove 43. The rotating sleeve 32 drives the second guide post 8 to slide along the second guide groove 44. The first vibrating comb 9 and the second vibrating comb 10 will reciprocate under the action of the second guide groove 44. The circumferential reciprocating rotation of the rotating shaft 31 and the rotating sleeve 32 will cause the first vibrating comb 9 and the second vibrating comb 10 to generate circumferential vibration. Through the combined motion of axial vibration and horizontal circumferential vibration, the branches and fruits are subjected to alternating forces in the vertical and horizontal directions at the same time, which significantly improves the thoroughness of the shaking off of ripe fruits. In addition, since the rotation directions of the first guide groove 43 and the second guide groove 44 are opposite, the circumferential motion directions of the rotating shaft 31 and the rotating sleeve 32 are also opposite, forcing the first vibrating comb 9 and the second vibrating comb 10 to form opposite vibrations in the circumferential direction. This opposite vibration can effectively increase the inertial difference between the fruit and the branches. Especially for ripe fruits with strong fruit stalk binding force, it can quickly break through the binding threshold through multi-directional shear force.

[0030] like Figure 2 As shown, the collection component 6 includes two conveyors 61 fixed to both sides of the bottom of the picking box 2. A closure 62 for fruit trees to pass through is installed between the two conveyors 61. A collection box 63 is provided at the end of the stroke of each conveyor 61. The shaken-down fruits fall into the conveyor 61 through the closure 62 and are transported by the conveyor 61 to the collection box 63 to complete the collection.

[0031] The work process is as follows:

[0032] S1: As Figure 1 As shown, during use, the tracked vehicle 1 moves the picking box 2, allowing the goji berry tree to pass through the inside of the picking box 2;

[0033] S2: As Figures 2 to 3 As shown, during the movement, the motor 51 drives the crank 52 to rotate, and pushes the lifting plate 54 to move up and down along the slide bar 11 through the rocker arm 53;

[0034] S3: As Figures 3 to 5 As shown, when the lifting plate 54 moves, it will synchronously drive the rotating shaft 31 to move up and down. At the same time, the rotating sleeve 32 moves up and down synchronously with the rotating shaft 31 under the restriction of the support plate 34 and the limiting ring 12, thereby causing the first vibrating comb 9 and the second vibrating comb 10 to generate axial vibration.

[0035] S4: As Figure 5 and Figure 8 As shown, during the up-and-down movement of the rotating shaft 31 and the rotating sleeve 32, the rotating shaft 31 drives the first guide post 7 to slide along the first guide groove 43 and reciprocates under the push of the first guide groove 43; the rotating sleeve 32 drives the second guide post 8 to slide along the second guide groove 44 and reciprocates under the action of the second guide groove 44.

[0036] S5: As Figure 5 and Figure 8 As shown, the circumferential reciprocating rotation of the rotating shaft 31 and the rotating sleeve 32 will cause the first vibrating comb 9 and the second vibrating comb 10 to generate circumferential vibration. Through the combined motion of axial vibration and horizontal circumferential vibration, the branches and fruits are simultaneously subjected to alternating forces in the vertical and horizontal directions, which significantly improves the thoroughness of shaking off ripe fruits. In addition, since the rotation directions of the first guide groove 43 and the second guide groove 44 are opposite, the circumferential motion directions of the rotating shaft 31 and the rotating sleeve 32 are also opposite, forcing the first vibrating comb 9 and the second vibrating comb 10 to form opposite vibrations in the circumferential direction. This opposite vibration can effectively increase the inertial difference between the fruit and the branches, especially for ripe fruits with strong fruit stalk binding force, which can quickly break through the binding threshold through multi-directional shear force.

[0037] S6: As Figure 2As shown, the shaken-off fruit falls into the conveyor 61 through the closure 62 and is then transported by the conveyor 61 to the collection box 63 for collection.

[0038] The conveyor 61, the closure device 62, and the motor 51 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.
