Description

[0002] Xinjiang, as a core jujube-producing area, has significantly improved yield per unit area and orchard management efficiency in recent years by promoting dwarf-dense planting models (row spacing of 2m-3m, plant spacing of 1m-1.5m, and canopy height less than or equal to 2.5m). However, during harvesting, harvesters work an average of over 8 hours per day, with a single person's harvesting efficiency less than 0.3 mu / day, which is insufficient to meet the harvesting efficiency requirements of large-scale planting. Especially in densely planted orchards, existing large vibratory harvesting equipment suffers from problems such as excessive machine width and excessively large minimum turning radius, resulting in insufficient inter-row passage and inter-plant adaptability, making it difficult to operate effectively.

When the pressure is too high, it can easily cause damage to the trunk, while when the pressure is too low, it can easily cause the clamping to become unstable. Although vibration harvesting with fixed parameters can achieve basic fruit drop, it can easily cause unnecessary drop of immature fruits and branches, resulting in economic losses.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0024] See Figure 1 and Figure 5 As shown, the present application provides a jujube harvesting test platform with a rocking gripping mechanism, including a flexible clamping mechanism 1. The flexible clamping mechanism 1 includes an auxiliary box 11 and a clamping assembly 12. The clamping assembly 12 is movably mounted on the auxiliary box 11. The clamping assembly 12 includes a first clamping member 121 and a second clamping member 122. The first clamping member 121 and the second clamping member 122 are arranged opposite to each other to form a clamping space. The second clamping member 122 is provided with an avoidance notch 1221 that cooperates with the first clamping member 121. The end face of the first clamping member 121 facing the clamping space and the end face of the second clamping member 122 facing the clamping space are both provided with a flexible buffer layer 13.

[0025] In this embodiment, the flexible buffer layer 13 includes, but is not limited to, polyurethane buffer pads, cross-linked polyethylene foam, silicone sponge and thermoplastic elastomers. As a preferred embodiment of this application, a polyurethane buffer pad is used as the flexible buffer layer 13.

[0026] Specifically, polyurethane cushioning pads can provide good energy absorption and rebound characteristics. Compared with other foam materials (such as PE foam), polyurethane foam usually has higher compressive strength at the same density, can withstand greater pressure without excessive deformation or collapse, and its performance decays relatively slowly under long-term repeated compression and rebound cyclic loads, thus having a longer service life. Therefore, polyurethane cushioning pads can be preferred as flexible cushioning layers 13.

[0027] In this embodiment, the first clamping member 121 and the second clamping member 122 are arranged opposite to each other and movably mounted on the auxiliary housing 11. This design allows the first clamping member 121 and the second clamping member 122 to form a dynamically adjustable clamping space. This enables the clamping assembly 12 to dynamically adjust the width of the clamping space according to the actual diameter of the tree trunk during force application. Furthermore, the second clamping member 122 is provided with an avoidance notch 1221. When clamping an irregular tree trunk with a small diameter, the avoidance notch 1221 allows the first clamping member 121 to partially embed into the second clamping member 122, thereby further reducing the clamping force. The width of the small clamping space is small, and both the end face of the first clamping member 121 facing the clamping space and the end face of the second clamping member 122 facing the clamping space are provided with a flexible buffer layer 13. The flexible buffer layer 13 can deform to form a clamping surface that conforms to the natural contour of the tree trunk, increasing the actual contact area with the tree trunk. The protruding parts of the tree trunk compress the flexible buffer layer 13, while the concave parts of the tree trunk are elastically backfilled and supported by the flexible buffer layer 13, avoiding damage to the phloem or cambium caused by rigid compression. This effectively solves the problem that the clamping device is difficult to adapt to the individual morphological differences of fruit trees, which leads to a large loss during the harvesting of jujubes.

[0028] In one embodiment of this application, the flexible clamping mechanism 1 further includes a driving member 14. Two driving members 14 are provided. The two ends of one driving member 14 are respectively connected to the auxiliary housing 11 and the first clamping member 121, and the two ends of the other driving member 14 are respectively connected to the auxiliary housing 11 and the second clamping member 122. The two driving members 14 drive the first clamping member 121 and the second clamping member 122 to switch between a closed state and an open state.

[0029] Specifically, the driving component 14 is a hydraulic push rod, which is controlled by a hydraulic servo system. The hydraulic system transmits energy through high-pressure fluid, and its output power per unit volume is higher than that of electric or pneumatic systems. By using hydraulic drive, it can achieve a large clamping force while avoiding the bulkiness of the flexible clamping mechanism 1. Secondly, the hydraulic oil has very low compressibility, which gives the hydraulic system high rigidity, effectively preventing slippage during clamping and ensuring the reliability of clamping.

[0030] The hydraulic drive can adjust the output force of the hydraulic cylinder in real time based on sensor feedback, realizing dynamic, closed-loop, and high-precision adjustment of the clamping force. The hydraulic drive and the polyurethane buffer layer work together to actively control and compensate for load fluctuations (such as trunk swaying), while the polyurethane buffer layer passively absorbs high-frequency micro-vibrations, thereby significantly reducing pressure fluctuations at the trunk clamping point and preventing damage to the trunk.

[0031] In one embodiment of this application, see Figure 5As shown, the auxiliary housing 11 has two first protrusions 111 arranged vertically and two second protrusions 112 arranged vertically at one end. The first clamping member 121 and the two first protrusions 111 are connected by a positioning pin 15, and the second clamping member 122 and the two second protrusions 112 are connected by a positioning pin 15.

[0032] The first protrusion 111, the second protrusion 112 and the auxiliary box 11 are integral parts made by an integral molding process, or the first protrusion 111, the second protrusion 112 and the auxiliary box 11 are separate parts, and the first protrusion 111 and the second protrusion 112 are respectively welded and fixed to the right end face of the auxiliary box 11 by a welding process.

[0033] Specifically, the first clamping member 121 is connected to two corresponding vertically arranged first protrusions 111 via a single positioning pin 15, and the second clamping member 122 is also connected to two corresponding vertically arranged second protrusions 112 via a single positioning pin 15. This design forms a double-lug hinge structure, allowing the first clamping member 121 and the second clamping member 122 to rotate around the positioning pin 15 connected to them. This restricts the degree of freedom of movement of the first clamping member 121 and the second clamping member 122 along the axial direction of the positioning pin 15, ensuring that the first clamping member 121 and the second clamping member 122 can only rotate around the positioning pin 15 connected to them when subjected to force, avoiding unexpected displacement or shaking, and ensuring the clamping stability of the flexible clamping mechanism 1.

[0034] In one embodiment of this application, see Figure 4 As shown, the jujube harvesting test bench includes a vibration mechanism 2, which includes a vibration box 21, a vibration motor 22, and N eccentric mass blocks 23. The vibration motor 22 is mounted on the vibration box 21, and the transmission shaft 221 of the vibration motor 22 extends through the box wall of the vibration box 21 and into the vibration box 21. The N eccentric mass blocks 23 are arranged sequentially along the length of the transmission shaft 221. In the height direction of the vibration box 21, the projections of the N eccentric mass blocks 23 are evenly distributed around the projection of the transmission shaft 221. Each eccentric mass block 23 is connected to the transmission shaft 221 through an expansion coupling 24. N is a natural number greater than or equal to 2.

[0035] In a preferred embodiment of this application, two excitation motors 22 are provided, and two eccentric mass blocks 23 are installed on the transmission shaft 221 of each excitation motor 22.

[0036] Specifically, N eccentric mass blocks 23 are arranged sequentially along the length of the transmission shaft 221. In the height direction of the vibration box 21, the projections of the N eccentric mass blocks 23 are evenly distributed around the projection of the transmission shaft 221. This design ensures that the centrifugal force generated by each eccentric mass block 23 during rotation is distributed at a predetermined angle in the horizontal plane. Compared with eccentric mass blocks 23 arranged in a single direction or in the same direction, this design can form a complex two-dimensional planar excitation force, which is more in line with the trunk shaking characteristics required for jujube harvesting. It can effectively disturb the branches, promote fruit drop, and thus improve harvesting efficiency.

[0037] The expansion sleeve coupling 24 has the characteristics of high torque transmission capacity, good centering and no backlash. Each eccentric mass block 23 is connected to the transmission main shaft 221 through the expansion sleeve coupling 24. This design can ensure that there is no relative sliding or lag between the eccentric mass block 23 and the transmission main shaft 221, achieve precise synchronous rotation, and ensure the stability of the composite excitation force vector. Secondly, it can also facilitate the quick installation or removal of the eccentric mass block 23.

[0038] When the excitation motor 22 starts, it transmits the torque of the excitation motor 22 to the expansion coupling 24 through the transmission main shaft 221, so as to drive the eccentric mass block 23 to generate inertial excitation force. The vibration energy is transmitted to the flexible clamping mechanism 1 through the vibration box 21, forcing the jujube tree trunk to produce two-dimensional plane forced vibration.

[0039] In one embodiment of this application, see Figures 2-3 As shown, the jujube harvesting test bench also includes a vibration isolation mechanism 3. The vibration isolation mechanism 3 includes a support platform 31 and a vibration isolation component 32. The support platform 31 includes a first support part 311 and a second support part 312, which are connected together. The vibration isolation component 32 includes a first rubber vibration isolator 321 and a second rubber vibration isolator 322. The first rubber vibration isolator 321 is disposed between the first support part 311 and the vibration box 21, and both ends of the first rubber vibration isolator 321 are respectively connected to a side wall of the vibration box 21 and the first support part 311 by fasteners 33. The second rubber vibration isolator 322 is disposed between the second support part 312 and the vibration box 21, and both ends of the second rubber vibration isolator 322 are respectively connected to the bottom wall of the vibration box 21 and the second support part 312 by fasteners 33.

[0040] Specifically, the first rubber vibration isolator 321 acts in the horizontal direction to suppress the transmission of excitation energy in the direction away from the flexible clamping mechanism 1; the second rubber vibration isolator 322 acts in the vertical direction to suppress the vertical vibration transmission of excitation energy. The first rubber vibration isolator 321, the second rubber vibration isolator 322 and the support platform 31 form a composite vibration isolation interface to prevent vibration energy from being transmitted to other mechanisms of the rocking jujube harvesting test platform through the support platform 31, thereby avoiding overall shaking, displacement or resonance of the platform.

[0041] See Figure 3 As shown, the jujube harvesting test bench also includes a frame assembly 4, which includes a base plate 41 and a vertical plate 42. The vertical plate 42 is installed on the base plate 41, and the vertical plate 42 and the base plate 41 are set at 90°.

[0042] In one embodiment of this application, see Figure 3 As shown, the jujube harvesting test platform also includes a height adjustment mechanism 5. The height adjustment mechanism 5 includes a linear module 51 and a laser rangefinder 52 arranged along the Z-axis. The linear module 51 is installed on one side of the upright plate 42. The linear module 51 includes a drive guide mechanism 511 and a slider 512. The slider 512 can move linearly along the extension direction of the drive guide mechanism 511. The first support part 311 is installed on the slider 512. The laser rangefinder 52 is installed on the vibration box 21, and the laser emission direction of the laser rangefinder 52 is perpendicular to the bottom surface of the frame assembly 4. With this design, the laser rangefinder 52 can provide real-time feedback on the current clamping position, and together with the linear module 51, it can achieve precise adjustment of the harvesting height, thereby realizing two-dimensional planar vibration harvesting of dwarf densely planted jujube trees.

[0043] In summary, the jujube harvesting test platform proposed in this utility model includes a flexible clamping mechanism 1. The flexible clamping mechanism 1 includes an auxiliary box 11 and a clamping assembly 12. The clamping assembly 12 is movably installed on the auxiliary box 11. The clamping assembly 12 includes a first clamping member 121 and a second clamping member 122. The first clamping member 121 and the second clamping member 122 are arranged opposite to each other to form a clamping space. The second clamping member 122 is provided with an avoidance notch 1221 that cooperates with the first clamping member 121. Both the end face of the first clamping member 121 facing the clamping space and the end face of the second clamping member 122 facing the clamping space are provided with a flexible buffer layer 13. The first clamping member 121 and the second clamping member 122 are arranged opposite to each other and movably mounted on the auxiliary housing 11. This design allows the first clamping member 121 and the second clamping member 122 to form a dynamically adjustable clamping space. This enables the clamping assembly 12 to dynamically adjust the width of the clamping space according to the actual diameter of the tree trunk during the application of force. Furthermore, the second clamping member 122 is provided with an avoidance notch 1221. When clamping irregular tree trunks with small diameters, the avoidance notch 1221 allows the first clamping member 121 to partially embed into the second clamping member 122, thereby further reducing the clamping force. The width of the holding space is increased, and both the end face of the first clamping member 121 facing the holding space and the end face of the second clamping member 122 facing the holding space are provided with flexible buffer layers 13. The flexible buffer layer 13 can deform to form a clamping surface that conforms to the natural contour of the tree trunk, increasing the actual contact area with the tree trunk. The protruding parts of the tree trunk compress the flexible buffer layer 13, while the concave parts of the tree trunk are elastically backfilled and supported by the flexible buffer layer 13, avoiding damage to the phloem or cambium caused by rigid compression. This effectively solves the problem that the clamping device is difficult to adapt to the individual morphological differences of fruit trees, which leads to a large loss during the harvesting of jujubes.
