Description

Technical Field

[0001] This utility model relates to the field of agricultural harvesting machinery technology, specifically to a goji berry fruit picking device, which is particularly suitable for mechanized harvesting in dwarf, densely planted goji berry orchards. Background Technology

[0002] Goji berries are an important economic crop in Northwest my country, and their planting area has expanded rapidly in recent years. Due to the thin skin and abundant juice of goji berries, the slender and soft branches, and the inconsistent ripening time, harvesting is still mainly done by hand, which is labor-intensive, inefficient, and costly. During peak harvesting seasons, there is often a difficulty in hiring workers, which has become a bottleneck restricting the large-scale development of the goji berry industry.

[0003] To address the aforementioned issues, various goji berry harvesting methods have emerged both domestically and internationally, which can be broadly categorized into the following three types: Vibration type: This method uses an eccentric vibration mechanism to clamp the trunk or main branches, causing the entire tree to vibrate and the fruit to fall off. This method causes significant damage to the tree, with mature and unripe fruits falling off simultaneously, making sorting difficult, and it is poorly adapted to dwarf, densely planted goji berry varieties.

[0004] Brush type: Rotating or reciprocating brush rollers act directly on the fruit branches, brushing the fruit off. The brushing force is difficult to control precisely, easily breaking thin and weak branches, and resulting in a high rate of fruit peel scratches.

[0005] The aforementioned methods have significant shortcomings in terms of fruit drop mechanisms, the interaction between the plant structure and the plant, and the control of fruit / leaf damage, making it difficult to simultaneously meet the comprehensive requirements of "high efficiency, low damage, and wide adaptability." Therefore, there is an urgent need for a new harvesting technology that can target the flexibility of wolfberry branches, the differences in fruit ripening, and the dwarfing and dense planting pattern, to achieve selective, low-damage, and high-efficiency mechanized harvesting. Utility Model Content

[0006] The purpose of this invention is to provide a goji berry fruit harvesting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following solution: A goji berry harvesting device includes a walking and carrying platform, a pulsed air blowing system, a branch picking system, and a receiving system. The walking and carrying platform carries the pulsed air blowing system, the branch picking system, and the receiving system and moves the goji berry harvesting device. The pulsed air blowing system generates pulsed airflow to blow down goji berries. The branch picking system picks up goji berry branches and guides them to a position corresponding to the pulsed air blowing system. The receiving system is located below the branch picking system and is used to receive goji berries.

[0008] Furthermore, the walking and carrying platform includes a drive chassis, a cab, and a gantry frame; The cab is mounted on the side of the gantry frame, and the drive chassis is located at the bottom of the gantry frame.

[0009] Furthermore, the pulsed air blowing system includes two sets of pulsed air blowing mechanisms correspondingly arranged on the left and right sides of the gantry frame; The pulsed air blowing mechanism includes an airflow generating component and an airflow distribution and purging component; The pulsating airflow generating assembly includes a fan, a pulsating airflow generator, and a flexible flared air duct; The pulsating airflow generator includes a horizontally arranged cylindrical shell, with an air inlet and an air outlet respectively opened at the upper and lower ends of the cylindrical shell; The cylindrical outer shell has a rotating shaft arranged inside along its axial direction; A middle partition plate is installed at the middle position of the rotating shaft, which divides the cylindrical inner cavity of the cylindrical shell into two chambers, left and right. The rotating shaft is also provided with two blades, which are located on both sides of the intermediate partition plate and are perpendicular to each other. A drive mechanism is provided on the outer side of the cylindrical outer shell, and the drive mechanism is connected to the rotating shaft; The upper inlet of the flexible flared air duct is connected to the air outlet of the fan, and the lower outlet is connected to the air inlet of the cylindrical shell. The air outlet of the cylindrical outer shell is connected to the airflow distribution and purging assembly.

[0010] Furthermore, the airflow distribution and purging assembly includes several sets of branch air ducts arranged along the axial direction of the cylindrical outer shell. The air inlets of several sets of branch air ducts are connected to the air outlets of the cylindrical outer shell; The air outlet of the branch duct is parallel to the horizontal line connecting the two sets of the pulsating air blowing mechanism.

[0011] Furthermore, the heights of the air outlets of several groups of branch air ducts are arranged sequentially from high to low or from low to high, and the air outlets of the branch air ducts are fitted with air nozzles.

[0012] Furthermore, the branch-picking system includes two sets of branch-picking mechanisms, which are respectively arranged below the two sets of pulsed air blowing mechanisms; The branch-picking mechanism includes two sets of correspondingly arranged actuating components; The actuation components include an electric push rod and a sliding component; The sliding assembly includes a slide rail and a slider that slide together. The electric push rod is horizontally positioned at the lower end of the slider; A self-winding cloth roller is provided between the two electric push rods of the two actuating components. A flexible receiving cloth is wound on the self-winding cloth roller, and the free end of the flexible receiving cloth is connected to the pushing end of the two electric push rods respectively.

[0013] Furthermore, the self-winding fabric roll includes a fabric roll, a rotating fixed seat, and a spiral spring; Both ends of the fabric roll shaft are connected to the worm springs via sleeves. The outer ring of the worm spring is fixed on the sleeve, and the inner ring is fixed on the rotating fixed seat. The rotating fixed base is connected to the electric push rod.

[0014] Furthermore, the actuation assembly also includes a gear drive assembly, which includes a rack, a gear, and an actuation motor; The rack is arranged along the direction of the slide rail; The actuating motor is mounted on the slider, and the output end of the actuating motor is fitted with the gear, which meshes with the rack.

[0015] Furthermore, the guide rail includes a straight section and an upper arc section; Limiting elements are provided at both ends of the slide rail.

[0016] Furthermore, the receiving system includes a receiving bag, which is hung on the lower side of the branch-picking system.

[0017] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows: By applying instantaneous and periodic impact force to mature fruits through pulsating airflow, the connection between green fruits and branches is maintained, significantly reducing the proportion of unripe fruits mixed in and improving the purity of marketable fruits. There is no rigid combing or high-frequency vibration throughout the process. The branches are only supported by flexible fabric and subjected to intermittent wind pressure, which significantly reduces the risk of fruit peel scratches, branch breakage and leaf drop, which is beneficial to tree health and the following year's yield.

[0018] The pulsating airflow generator has a purely mechanical blade structure, eliminating the need for complex hydraulic servo systems. The pulsating operating mode reduces the average load on the fan, resulting in lower power requirements and lower manufacturing and maintenance costs compared to existing combing or continuous strong wind solutions.

[0019] The adjustable height of the branch ventilation outlet and the detachable and replaceable combination of the air outlet and the branch picking mechanism allow the machine to cover a large area of ​​canopy height in one pass. It can be used in dwarf densely planted wolfberry gardens with small row spacing. At the same time, the parameters can be adjusted to extend the harvesting of small berries such as black wolfberry and sea buckthorn, realizing the multi-purpose use of one machine.

[0027] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0028] Example

[0029] See Figure 1 As shown in the figure, the wolfberry fruit harvesting device provided in this embodiment includes a walking and carrying platform, a pulsed air blowing system 25, a branch picking system 26, and a material receiving system. The walking and carrying platform is used to carry the pulsed air blowing system 25, the branch picking system 26, and the material receiving system and drive the wolfberry fruit harvesting device to move. The pulsed air blowing system 25 is used to generate pulsed airflow to blow down the wolfberry fruit. The branch picking system 26 is used to pick up the wolfberry branches and guide them to the position corresponding to the pulsed air blowing system 25. The material receiving system is set below the branch picking system 26 and is used to receive the wolfberry fruit.

[0030] Specifically, see Figure 1 As shown, the traveling and load-bearing platform includes a drive chassis 1, a cab 2, and a gantry frame 3; The cab 2 is mounted on the side of the gantry frame 3, and the drive chassis 1 is located at the bottom of the gantry frame 3.

[0031] The drive chassis 1 has four wheels. The driver controls the entire device from inside the cab 2, thereby controlling the device's walking, steering, parking, and other functions. The control system inside the cab 2 can also control the pulsed air blowing system 25 and the branch picking system 26.

[0032] The overall workflow of the machine is as follows: The goji berry harvesting device travels to the working area and stops. The lower branch-picking system 26 operates to hold and wrap the goji berry branches, while the upper pulsating air blowing system 25 operates, blowing pulsating air to blow the ripe goji berries off, onto the branch-picking system 26, and into the receiving system. Harvesting is now complete. The pulsating air blowing system 25 stops operating, the branch-picking system 26 retracts, and the device moves to the next working area.

[0033] Specifically, since immature goji berries (green berries) are more firmly attached to branches than mature goji berries (ripe berries), they are difficult to blow off by pulsating wind. Mature goji berries, on the other hand, are very fragile because they are already ripe, and can be easily blown off by pulsating wind. This effectively selects mature goji berries, greatly improving both harvesting efficiency and quality.

[0034] Specifically, see Figure 2-4 As shown, the pulsed air blowing system 25 includes two sets of pulsed air blowing mechanisms correspondingly arranged on the left and right sides of the gantry frame 3. The pulsed air blowing mechanism includes an airflow generating component and an airflow distribution and purging component; The pulsating airflow generating assembly includes a fan 4, a pulsating airflow generator 5, and a flexible flared air duct 6; The pulsating airflow generator 5 includes a horizontally arranged cylindrical shell 7, with an air inlet and an air outlet at the upper and lower ends of the cylindrical shell 7, respectively. A rotating shaft 8 is provided inside the cylindrical outer shell 7 along its axial direction; A middle partition plate 9 is installed in the middle of the rotating shaft 8, which divides the cylindrical inner cavity of the cylindrical outer shell 7 into two chambers, left and right. Two blades 10 are also provided on the rotating shaft 8. The two blades 10 are located on both sides of the intermediate partition plate 9, and the two blades 10 are perpendicular to each other. A drive mechanism 11 is provided on the outside of the cylindrical outer shell 7, and the drive mechanism 11 is connected to the rotating shaft 8; The upper inlet of the flexible flared air duct 6 is connected to the air outlet of the fan 4, and the lower outlet is connected to the air inlet of the cylindrical shell 7. The air outlet of the cylindrical housing 7 is connected to the airflow distribution and purging assembly.

[0035] It should be noted that a rubber damping pad can be laid under the installation position of the fan 4 to reduce vibration, and the flexible flared air duct 6 can also absorb the vibration brought by the fan 4 and prevent resonance.

[0036] Specifically, the blades 10 are driven by a motor to make circular motion. The movement of the blades 10 continuously opens and closes (blocks or opens) the air outlet of the cylindrical outer shell 7, periodically hindering the airflow and thus forming a pulsating airflow. There is an intermediate partition plate 9 between the two blades 10, which is intended to split the airflow into two channels, making the airflow inconsistent and creating turbulence in the picking area, which can better blow down the goji berries.

[0037] In addition, the drive mechanism 11 can be a commonly used motor, which is connected to the rotating shaft 8 via a coupling. The motor is fixed to the gantry frame via a connecting plate, and the side of the cylindrical housing 7 opposite to the motor is set as a detachable plate so that the rotating shaft 8 can be installed and removed inside the cylindrical housing 7.

[0038] In addition, the blade 10 in this embodiment is a flat straight plate. When it is necessary to adjust the pulsating wind, the shape of the blade 10 can be changed to a curved surface, or some holes can be opened on the plate surface of the blade 10 to make the airflow compression and passage smoother.

[0039] The principle of pulsating airflow in the airflow generating component is as follows: A motor on one side of the cylindrical outer shell 7 drives the rotating shaft 8 to rotate, which in turn causes the blades 10 to rotate. Viewed vertically, during the rotation of the blades 10, when they reach a horizontal position, the airflow is blocked by the blades 10 and cannot pass through the air outlet of the cylindrical outer shell 7; the air is compressed at the air outlet. As the blades 10 continue to rotate, a space is formed between the blades 10 and the air outlet of the cylindrical outer shell 7, allowing airflow to pass through. This space gradually increases in size, allowing air to pass through until the blades 10 rotate to the vertical air duct inlet, where the airflow can pass through the generator at maximum flow rate. This process repeats continuously, and the repeated rotation of the blades 10 creates pulsating airflow. The frequency of the pulsating airflow can be controlled by adjusting the motor speed to achieve optimal harvesting pulsating airflow.

[0040] Specifically, see Figure 2 As shown, the airflow distribution and purging assembly includes several sets of branch air ducts 12 arranged along the axial direction of the cylindrical outer shell 7. The air inlets of several sets of branch air ducts 12 are connected to the air outlets of the cylindrical outer shell 7; The air outlet of branch duct 12 is parallel to the horizontal line connecting the two sets of pulsating air blowing mechanisms.

[0041] In this embodiment, six sets of branch air ducts 12 are provided. The height of the air outlets of the six sets of branch air ducts 12 is arranged sequentially from high to low or from low to high to meet the harvesting needs of plants at different heights. The air outlets of the branch air ducts 12 are fitted with air nozzles 13, which can be disassembled and replaced. The size of the air outlet of the air nozzle 13 can be adjusted according to the actual situation to obtain the ideal airflow.

[0042] Furthermore, the vertical arrangement of the branch ducts 12 of the airflow distribution and purging assembly in the pulsed air blowing mechanism can be staggered, forming an overall X-shape, such as... Figure 2 As shown, the purpose is to stagger the air supply on both sides in the air blowing working area, so that the air flows cross and further form turbulence, resulting in better harvesting effect.

[0043] Specifically, the branch-carrying system 26 includes two sets of branch-carrying mechanisms, which are respectively arranged below the two sets of pulsating air blowing mechanisms. like Figure 5 As shown, the branch-picking mechanism includes two sets of correspondingly arranged actuating components; The actuation components include an electric actuator 14 and a sliding assembly; The sliding assembly includes a slide rail 15 and a slider 16 that slide and engage with each other. An electric push rod 14 is horizontally mounted at the lower end of slider 16; A self-winding cloth roller is provided between the two electric push rods 14 of the two actuation components. A flexible receiving cloth 17 is wound on the self-winding cloth roller, and the free end of the flexible receiving cloth 17 is connected to the pushing end of the two electric push rods 14 respectively.

[0044] like Figure 6 As shown, the self-winding fabric winding shaft includes a fabric winding shaft 18, a rotating fixed seat 19, and a worm spring 20. Both ends of the fabric roll shaft 18 are connected to a worm spring 20 via a sleeve. The outer ring of the worm spring 20 is fixed on the sleeve, and the inner ring is fixed on the rotating fixed seat 19. The rotating fixed base 19 is connected to the electric push rod 14.

[0045] The actuation assembly also includes a gear drive assembly, which includes a rack, a gear, and an actuation motor 21; The rack is arranged along the direction of slide rail 15; The actuating motor 21 is mounted on the slider 16, and a gear is fitted at the output end of the actuating motor 21, which meshes with the rack.

[0046] See Figure 5 As shown, the path of slide rail 15 includes a straight section and an upper arc section; Limiting elements 22 are provided at both ends of the slide rail 15.

[0047] See Figure 1 As shown, the receiving system includes a receiving bag 23, which is hung on the lower side of the branch-carrying system 26. Specifically, the receiving bag 23 is made of flexible material and is strung on two rods, one in front of the other, mounted on the lower side of the branch-carrying mechanism, allowing it to be installed and removed at any time. All the flexible fabric is designed to protect the fallen fruit and prevent the mature fruit from breaking.

[0048] In addition, see Figure 1 As shown, two branch-lifting poles 24 are symmetrically arranged on the gantry frame 3. The arrangement direction of the branch-lifting poles 24 is parallel to the overall forward direction of the device, and it is a contour design from low to high. It can gently lift the lower branches that are hanging on the ground as the device moves forward and lift them to the blowing position of the pulsed air blowing system 25.

[0049] Specifically, the limiting component 22 is a photoelectric limit switch, which works in conjunction with the actuating motor 21 to control the movement range of the slider 16 and prevent it from exceeding its designed stroke. The slide rail 15 has support rollers in its track to reduce friction during slider 16 movement and ensure smooth operation. Furthermore, adjusting shims are provided between the slide rail 15 and the gantry frame 3 to compensate for manufacturing and installation errors, ensuring smooth operation of the slider 16 on the slide rail 15. The slide rail surface is hardened to improve wear resistance and service life.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
