Description

Technical Field

[0001] The present invention relates to the technical field of wolfberry picking, in particular to a wolfberry picking vehicle and a picking method. Background Art

[0002] Wolfberry is a berry with indeterminate inflorescences and continuous flowers and fruits. As an important traditional Chinese medicine and tonic, it has multiple health and medical benefits. Harvesting is highly seasonal, from the end of June to the end of October each year, with a harvest cycle of 5-7 days. Existing wolfberry harvesting equipment typically designs the vibration device, receiving device, conveying device, sorting device, and collection device into independent units, each with different functions. This decentralized layout lacks effective overall coordination, making the entire wolfberry harvesting process cumbersome and complicated, requiring more manpower and time for coordination and management.

[0003] Patent No. 201520804869.1 discloses an air-suction wolfberry picker. This machine uses an induced draft fan to create negative pressure within an air outlet hose. A suction nozzle then pulls the berries onto a vacuum cup and into the suction hose. The harvested berries are then deposited into a storage bin. However, picking wolfberries typically takes a long time, requiring both hands to perform a series of operations, which can cause arm fatigue and result in low picking efficiency.

[0004] Patent No. 202410510045.7 discloses a self-propelled goji berry collection and processing device. The device uses a vibrating rod to pick goji berries. The goji berries are then transported via a first transmission assembly to a second transmission assembly. The goji berries are screened by a screening assembly and then collected in a collection trough. However, the vibration during the transport process and the wind force generated by the air pump can cause some goji berries to fall outside the conveyor belt, causing excessive damage to the goji berries and affecting their economic value.

[0005] At the same time, when the picking device in the existing technology is used in the field to pick wolfberries, it has great limitations on picking wolfberry plants with different row spacings, has poor adaptability, is relatively complex in structure, does not reflect the position of the operator, and relies entirely on the machine's arrayed vibration unit picking system.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figure 1-Figure 5 The present invention provides a wolfberry picking vehicle, comprising:

[0037] A vehicle body 1 is provided with a driver and multiple pickers, the pickers are arranged along the axis, and two adjacent pickers pick the wolfberries at the bottom and top respectively;

[0038] The receiving device 2 is installed on the side of the vehicle body 1 close to the pickers, and the wolfberries picked by the pickers fall onto the receiving device 2;

[0039] The screening device 3 is installed at the rear end of the vehicle body 1 and is connected to the receiving device 2. The screening device 3 is used to screen the wolfberries on the receiving device 2;

[0040] The collecting device 4 is installed at the front end of the vehicle body 1 and is connected to the screening device 3. The collecting device 4 is used to collect the screened wolfberries.

[0041] In one embodiment of the present application, the pickers are arranged axially and sit on the vehicle body 1 in an alternating high and low distribution. The driver controls the movement of the vehicle body 1. After the pickers pick the wolfberries, the wolfberries fall onto the receiving device 2 below and are transported to the screening device 3. After screening by the screening device 3, the wolfberry fruits are transported to the collecting device 4.

[0042] As an optional embodiment, the vehicle body 1 includes a chassis 16 , on which an operating console 11 , a driver's seat 12 , a distribution box 13 and a workstation seat 15 are mounted, and movable wheels 14 are mounted at the bottom of the chassis 16 .

[0043] In one embodiment of the present application, the driver is seated on the driver's seat 12 and notifies the vehicle to move through the operating console 11 .

[0044] As an optional embodiment, the workstation chair 15 includes a plurality of high-station chairs and a plurality of low-station seats, and the plurality of high-station chairs and the plurality of low-station chairs are staggered.

[0045] In one embodiment of the present application, the workstation seats 15 include several high-station seats and several low-station seats. By adjusting the height of the low-station seats to adapt to wolfberry plants of different heights and densities, it is ensured that the pickers can work efficiently in the most comfortable posture. In order to adapt to various working environments, the height of the low-station seats can be freely adjusted to meet the needs of pickers of different heights, reduce labor fatigue, and improve work efficiency. After the driver drives the picking car to each workstation, the pickers sitting on the high and low-station seats pick the wolfberry plants in front of them. After picking is completed, they proceed to the next workstation. The pickers at the high workstation can pick the wolfberry plants that the pickers at the low workstation did not pick at the previous workstation. In this way, after the driver drives the picking car to the workstation twice, it can be ensured that the wolfberry plants are picked cleanly and the fruit leakage rate is reduced.

[0046] As an optional embodiment, the receiving device includes a cross beam 21, which is fixedly connected to the chassis 16.

[0048] As an optional embodiment, a winch column 26 is fixedly connected to the middle part of the crossbeam 21, a winch 27 is installed on the winch column 26, the lifting end of the winch 27 is connected to the supporting frame 23, a slide rail welding plate 28 is installed on the lifting platform column 22, a slide rail 29 is installed on the supporting frame 23, and the slide rail 29 is adapted to the slide rail welding plate 28.

[0049] In one embodiment of the present application, the receiving frame 23 is driven to move by a winch 27 , thereby adjusting the height of the receiving frame 23 .

[0050] As an optional embodiment, the screening device 3 includes a receiving conveyor belt 31, which is installed on the receiving frame 23 through a supporting conveyor belt bracket; a lifting conveyor belt 32, which is fixedly connected to the chassis 16 through the lifting conveyor belt bracket, and the top of the chassis 16 is fixedly connected with a bellows chamber 33, and a bellows funnel 34 is installed on the top of the bellows chamber 33, and the bellows funnel 34 is located below one end of the lifting conveyor belt 32, and a centrifugal fan 35 is installed on the side wall of the bellows chamber 33; a horizontal conveyor belt 36 is installed on the chassis 16 and connected to the bellows chamber 33.

[0051] In one embodiment of the present application, a high-speed airflow is generated by a centrifugal fan 35 and passes through the bellows chamber 33. By adjusting the wind speed, the fruit leaves can be effectively separated.

[0052] As an optional embodiment, the collecting device 4 includes a guide rail groove 44, which is mounted on the chassis 16 through a support leg 45. A guide rail slider 43 is provided in the guide rail groove 44, and a fruit basket 41 is slidably connected to the guide rail slider 43. The fruit basket 41 is located below one end of the horizontal conveyor belt 36.

[0053] In one embodiment of the present application, a fruit basket 41 is provided to collect the winnowed wolfberry fruits.

[0054] As an optional embodiment, a limit stop rod 42 is provided on the guide rail groove 44 , and the limit stop rod 42 is in limit contact with the fruit basket 41 .

[0055] In one embodiment of the present application, the fruit basket 41 is limited and blocked by a limit stop bar 42 .

[0056] As an optional implementation, the receiving frame 23 is covered with elastic cloth.

[0057] In one embodiment of the present application, a flexible contact method is adopted by setting an elastic cloth to ensure that the fruit is not damaged during contact.

[0058] A wolfberry picking method comprises the following steps:

[0059] The pickers are arranged along the axial direction and sit on the vehicle body 1 in a staggered distribution of high and low positions. The driver controls the movement of the vehicle body 1.

[0060] After the pickers pick the wolfberries, they fall onto the receiving device 2 below and are transported to the screening device 3;

[0061] After being screened by the screening device 3 , the wolfberry fruits are transported to the collecting device 4 .

[0062] In one embodiment of the present application, when performing operations, the pickers sit on high and low workstation seats. By adjusting the height of the low workstation seat to accommodate wolfberry plants of different heights and densities, the pickers are ensured to perform efficient operations in the most comfortable posture. In order to adapt to various working environments, the height of the low workstation seat can be freely adjusted to meet the needs of pickers of different heights, reduce labor fatigue, and improve work efficiency. After the driver drives the picking vehicle to each workstation, the pickers sitting on the high and low workstation seats pick the wolfberry plants in front of them. After the picking is completed, they proceed to the next workstation. The pickers at the high workstation can pick the wolfberry plants that the pickers at the low workstation have not picked when they were at the previous workstation. In this way, after the driver drives the picking vehicle to two workstations, it can be ensured that the wolfberry plants are picked cleanly, reducing the rate of missed fruits. The operator uses a picking head to vibrate and pluck the wolfberry branches. The fallen wolfberry fruits and leaves fall into the receiving rack 23, which is wrapped with highly elastic cloth and adopts a flexible contact method to ensure that the fruits are not damaged when they come into contact. The fruits and leaves fall onto the receiving conveyor belt 31. The fruits and leaves are transported by the receiving conveyor belt 31, then fall onto the lifting conveyor belt 32, and are transported to the top and enter the air separation area. The centrifugal fan 35 generates a high-speed airflow through the bellows chamber 33. By adjusting the wind speed, the fruit leaves can be effectively separated. After air separation, the fruits fall onto the horizontal conveyor belt 36 for transportation. Finally, the fruits fall into the fruit basket 41 for movement. During this period, the staff in the cab can adjust the speed and wind speed of each conveyor belt and centrifugal fan to make appropriate adjustments to the wolfberry transportation and air separation according to different situations to ensure the entire process is smooth and efficient.

[0063] The present application provides a wolfberry picking vehicle and a picking method. The high and low workstation seats can adjust the seat height according to the operator's own height to meet the needs of pickers of different heights, reduce labor fatigue, and improve work efficiency. Flexible contact is adopted in the receiving device. When the pickers pick wolfberries, the receiving frame is wrapped with strong elastic fabric to cover the space area where the wolfberries fall. The wolfberries are subjected to flexible contact, which greatly reduces the damage to the wolfberries and reduces the breakage rate. A circular method is adopted for transporting wolfberries. There are three conveyor belts that are linked together to better transport the wolfberries to the designated collection area. There is also an air separation device during the transportation process. A centrifugal fan is used with strong wind force and appropriate power, which meets the power requirements of the entire vehicle and can well separate the picked fruit leaves, with a high picking rate. The collecting device uses a guide rail slider to move the fruit basket with collected fruits, which reduces labor, saves time and effort, is easy to operate, and improves work efficiency.
