[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figures 1 to 6 This invention discloses a high-efficiency, low-loss harvesting platform for wolfberries, comprising:

[0058] The vehicle body assembly has a driver's seat and several picking units on one side of the vehicle body assembly.

[0076] As an optional implementation, the harvesting unit includes:

[0077] The collection and storage device 9 is slidably mounted on the vehicle body 12, and the feed end of the collection and storage device 9 is connected to the fruit outlet of the secondary air separator 2.

[0078] As an optional implementation method, high and low workstations include:

[0079] The high station 6 and the low station 10 are both mounted on the vehicle body 12 by means of lifting rods. The low station 10 is fixed with a pedal 13.

[0080] The harvesting vehicle includes a body 12, a driver's seat, and several sets of high and low workstations. Each set includes a high workstation 6 and a low workstation 10, both of which can be finely adjusted vertically. A fully automatic adjustable seat system provides a comfortable working environment for the harvesters. The seat height and angle can be adjusted according to the harvester's height and working habits to reduce fatigue from prolonged work.

[0081] As an optional implementation, the harvesting device includes a number of vibrating harvesting heads 7, the number of which matches the total number of high-station 6 and low-station 10, and the vibrating harvesting heads 7 correspond one-to-one with high-station 6 / low-station 10.

[0082] The vibrating harvesting head 7 includes:

[0083] Motor 702, with its fixed end fixedly connected to the bottom of the corresponding high station 6 / low station 10;

[0084] The controller and speed regulator 701 are electrically connected to the motor 702, and the controller and speed regulator 701 are fixed to the bottom of the corresponding high position 6 / low position 10.

[0085] Connecting flexible shaft 703, one end of which is shaft-connected to the output shaft of motor 702;

[0086] The eccentric wheel 704 is axially connected to the other end of the connecting flexible shaft 703 on one side, and a transmission rod is fixedly connected to the other side of the eccentric wheel 704. The transmission rod is eccentrically set.

[0087] The outer casing 705 is sleeved on the outside of the eccentric wheel 704, and the outer casing 705 is rotatably connected to the eccentric wheel 704.

[0089] The lever 707 is fixedly connected to the slider 706.

[0090] The harvesting vehicle body is the basic action unit and main structural frame of the wolfberry human-machine integrated harvesting vehicle. The harvesting device includes several vibrating harvesting heads 7 installed on the vehicle body 12. The number of vibrating harvesting heads 7 matches the number of high workstations 6 and low workstations 10. Each high workstation 6 / low workstation 10 corresponds to one vibrating harvesting head 7.

[0091] Each high station 6 / low station 10 has a controller and speed regulator 701 at its bottom for providing harvesting excitation force. A start switch is provided at the handheld part of the vibrating harvesting head 7.

[0092] Both the height-adjustable high station 6 and the height-adjustable low station 10 are equipped with lifting buttons below them, allowing for flexible adjustment of the harvesting height according to the angle of the fruit trees during the harvesting process, thereby increasing harvesting efficiency.

[0093] Meanwhile, the vibration speed of the vibrating harvesting head 7 is adjustable, and its adjustment button is located at the bottom of each high and low working position. By reasonably controlling and adjusting the vibration speed of the vibrating harvesting head, the fruit harvest rate can be improved and the damage and impurity rate can be reduced.

[0094] The vibrating picking head 7 is the core part of this device. It adopts a vibrating picking head, which converts the circular motion of the eccentric wheel 704 into the reciprocating swing of the slider 706, causing the lever 707 to collide with the wolfberry branches at a high frequency, and using inertia to shake the mature fruit off.

[0095] The vibration frequency of the vibrating harvesting head 7 is adjustable to adapt to the harvesting needs of different goji berry tree species. At the same time, the design of the harvesting device also takes into account the harvesting range and harvesting efficiency, ensuring that under comfortable working conditions, it can complete the harvesting of one side of four shrubs at one time.

[0096] As an optional implementation, the collection device includes a plurality of negative pressure collection devices 8, the number of which matches the total number of high station 6 and low station 10, and the negative pressure collection devices 8 correspond one-to-one with high station 6 / low station 10.

[0097] The negative pressure collection device 8 includes:

[0098] Support mounting component 802;

[0099] Several keels 804 are hinged at one end to the support mounting piece 802;

[0100] The flexible collection tray 801 is fixedly connected to several keels 804;

[0101] The corrugated pipe 803 is connected at one end to the support mounting part 802, and at the other end to the feed end of the air classifier. The corrugated pipe 803 is connected to the flexible collection tray 801 through the support mounting part 802.

[0102] The negative pressure collection device 8 has an arc-shaped support surface. The negative pressure collection device 8 is composed of an arc-shaped flexible collection disc 801, a support mounting component 802, a keel 804, and a corrugated pipe 803. The flexible collection disc 801 is supported by the corrugated pipe 803. The keel 804 is fixedly connected to the inner side of the flexible collection disc 801 by rivets. The keel 804 is hinged on the support mounting component 802. The corrugated pipe 803 is installed on the support mounting component 802. The middle part of the flexible collection disc 801 is connected to the corrugated pipe 803.

[0103] The negative pressure collection device 8 is responsible for receiving the goji berries shaken off from the vibrating picking head 7. It uses a flexible arc-shaped collection tray 801, and the material in the flexible collection tray 801 is sucked into the primary air separator 803 by the negative pressure suction generated by the primary air separator 5 on the corrugated pipe 803.

[0104] The flexible collection tray 801 uses a plain weave fabric to reduce the breakage rate during fruit collection.

[0105] As an optional implementation, the air separation device includes:

[0106] The primary air separator 5 is fixed to the vehicle body 12. The primary air separator 5 includes a primary air separator box, a fan, and a filter screen 14. The top of the primary air separator box is connected to the bottom of the corrugated pipe 803. The primary air separator box is fixed to the vehicle body 12. The bottom of the primary air separator box is provided with a discharge port that is connected to the horizontal conveyor belt 4. The fan is installed at one end of the primary air separator box, and an opening is provided at the other end of the primary air separator box. The filter screen 14 is installed on both sides of the opening.

[0107] The air separation system of this device consists of a primary air separator 5 and a secondary air separator 2. One primary air separator 5 is installed at each of the upper and lower workstations. The primary air separator 5 consists of a primary air separator housing, a blower, and a filter screen 14. A corrugated pipe 803 is connected to the top of the primary air separator housing, and a discharge port connected to the horizontal conveyor belt 4 is provided at the bottom of the primary air separator housing. The blower is installed at one end of the primary air separator housing, and an opening is provided at the other end of the primary air separator housing. The filter screen 14 is installed on both sides of the opening, which is used by the blower to remove impurities from the fruit.

[0108] The high-speed airflow is generated inside the primary air separator due to the action of the fan, and the top of the primary air separator is connected to the corrugated pipe 803. The high-speed airflow creates a negative pressure inside the corrugated pipe 803, which can perform negative pressure adsorption on the material on the flexible collection tray 801.

[0109] The horizontal conveyor belt 4 receives the goji berries after air separation. The fan speed is adjustable; by adjusting the optimal speed, the collected mixture of goji berries and leaves is screened, and the filter screen 14 ensures that the goji berries fall precisely onto the horizontal conveyor belt. The secondary air separator 2 is installed below the longitudinal conveyor belt 3. The secondary air separator 2 has the same structure as the primary air separator 5, so it will not be described in detail. The secondary air separator 2 performs secondary air separation on the goji berries obtained after the primary air separation on the horizontal conveyor belt 4. Below the secondary air separator 2 is the collection and storage device 9.

[0110] First and second-stage air separation ensures maximum separation of leaves and goji berries.

[0111] The conveying section consists of a horizontal conveyor belt 4, a longitudinal conveyor belt 3, and a collection and storage device 9. The horizontal conveyor belt 4 is located below several primary air separators 5. It is responsible for collecting the goji berry and leaf mixture from each station after primary air separation. The longitudinal conveyor belt 3 is located to the left of the horizontal conveyor belt 4. It collects the goji berry and leaf mixture conveyed by the horizontal conveyor belt 4 and provides vertical space for secondary air separation of the goji berry and leaf mixture. The horizontal conveyor belt within the collection and storage device 9 is located below the secondary air separator 2, conveying the goji berries after secondary air separation into the collection and storage device 9.

[0112] The primary air separator 5 and the secondary air separator 2 achieve the effect of air separation of wolfberry fruits and further reduce the damage rate.

[0113] After the fruit enters the air separation device, the heavier fruit will fall into the collection box, while the lighter impurities will be blown out of the machine.

[0114] The design of the air separation device also takes into account the cleaning rate and loss rate of the fruit to ensure that the quality of the finally collected fruit meets the requirements.

[0115] The collection and storage device 9 is responsible for receiving and storing the goji berries separated from the air separation device.

[0116] The collection and storage device 9 is designed with capacity and portability in mind to ensure that it can hold a sufficient number of fruits and facilitate subsequent transportation and processing by growers.

[0117] An operating box 15 for controlling the operation of the equipment is installed on one side of the vehicle body 12. The operating box 15 is used to control the opening and closing of the longitudinal conveyor belt 3, the horizontal conveyor belt 4, the primary air separator 5, and the secondary air separator 2.

[0118] An integrated operation method for a high-efficiency, low-loss goji berry harvesting platform, using the aforementioned high-efficiency, low-loss goji berry harvesting platform, includes the following steps:

[0119] Equipment inspection and debugging are performed to move the vehicle body components to the designated positions, adjust the high and low positions, and start the conveyor components;

[0120] After putting on protective gear, the personnel sat on high and low workstations, each holding a picking device and a collection device.

[0121] Start the harvesting device and adjust the vibration frequency of the harvesting device according to the density and maturity of the fruit to shake the fruit to the collection device. The collection device sends the fruit to the air separation device for air separation. After separation, the fruit is transported to the harvesting unit for storage through the conveying component.

[0122] Equipment inspection and commissioning

[0123] Before starting the equipment, operators must conduct a comprehensive inspection of the harvesting vehicle to ensure that all parts are intact, especially key components such as the vibrating harvesting head, conveyor belt, receiving plate, and axial flow fan.

[0124] Adjust the vibration frequency of the vibrating harvesting head, and set an appropriate harvesting force based on the growth of goji berries and the optimal parameters determined by experiments (such as a vibration frequency of 20Hz) to reduce fruit damage and improve the harvesting rate.

[0125] Human-machine collaboration preparation:

[0126] Operators should wear appropriate safety protective equipment, such as safety helmets, safety glasses, and gloves.

[0127] The workers at different workstations adjusted their positions to ensure that each group could collect goji berries from every goji tree. After adjusting their positions, the workers held the receiving device in their left hand and the collector in their right.

[0128] II. Harvesting Operation Stage

[0129] Start the vibrating harvesting head:

[0130] Operators at different work positions activate the vibrating harvesting head, which then begins to work, shaking off the ripe fruit in a non-contact manner, thus avoiding direct damage to the goji berry tree and the fruit.

[0131] Fruit receiving and transshipment:

[0132] After being shaken, the goji berries fall into a pre-designed receiving device. The optimal receiving height and dimensions of this device were determined through simulation and physical experiments to ensure that the berries fall smoothly without damage.

[0133] Each set of high and low stations is equipped with a fan. The goji berries in the receiving device are fed into an axial flow fan and a secondary buffer device for air separation. By adjusting the wind speed and direction, this device separates leaves, impurities, and other debris from the berries, further reducing the berry damage rate.

[0134] After being air-sorted, the goji berries are transferred without damage via a two-stage conveyor belt and an intermediate receiving plate. The conveyor belt design takes into account the characteristics of the goji berries and the impact during the transfer process, and uses flexible materials to reduce the breakage rate of the berries.

[0135] After being winnowed, the goji berries are collected in storage devices for easy transport and processing.

[0136] Human-machine collaborative harvesting:

[0137] Operators adjust the position and angle of the harvesting arm as needed to ensure that the vibrating harvesting head can cover more goji berry trees.

[0138] At the same time, operators should also pay attention to any abnormalities during the harvesting process, such as blockage of the vibrating harvesting head or poor fruit transport, and deal with them in a timely manner.

[0139] Real-time monitoring and adjustment:

[0140] During the harvesting process, operators need to monitor the equipment's operation and harvesting results in real time. If problems such as low harvesting efficiency or increased fruit damage are found, adjustments and optimizations must be made promptly.

[0141] III. Completion of Work Phase

[0142] Equipment cleaning and maintenance:

[0143] After the harvesting operation is completed, the operators need to thoroughly clean and maintain the equipment, especially the key components such as the vibrating harvesting head, conveyor belt, and receiving plate.

[0144] Inspect the equipment for wear and tear, replace damaged parts promptly, and ensure the long-term stable operation of the equipment.
