Description

Technical Field

[0001] This invention relates to the field of wolfberry fruit harvesting technology, and in particular to a wolfberry fruit blowing device. Background Technology

[0002] Goji berries, also known as Ningxia goji berries, Chinese goji berries, etc., are perennial woody plants belonging to the genus *Lycium* in the Solanaceae family. They have slender, arching or drooping branches that are pale gray; leaves are ovate; flowers grow singly or in pairs on long branches in the leaf axils; the fruit is an ovoid berry, red in color; flowering occurs from June to July; fruiting occurs from August to October. Goji berries originated in China, primarily in Northwest China, with Ningxia, Gansu, and Qinghai being the main production areas. They gradually spread throughout the country and to other parts of the world, and are now widely distributed in temperate and subtropical regions. They are cultivated in most provinces of northern China, often growing on hillsides, roadsides, or near villages. Goji berries prefer sunlight and cool climates, are cold-hardy, and have strong drought resistance, able to grow even in arid deserts. They are also salt-tolerant, growing best in alkaline soils and sandy loam, but thrive best in deep, fertile loam. Goji berries are generally propagated through seeds or cuttings.

[0003] Currently, the most common method for harvesting goji berries is by machine, which uses airflow to blow mature berries off the tree and then collects them. However, existing goji berry fruit blowing devices have the following shortcomings in actual use: existing devices generally use constant wind speed or simple variable frequency airflow, resulting in a steady laminar flow. This is insufficient to provide instantaneous shear force for the abscission layer of the goji berry stalk. Furthermore, the air duct of the device is a single straight cylinder or a simple funnel structure, with uniform outlet wind speed distribution. This makes it impossible to form an airflow field with constantly changing direction and intensity within the dense canopy. The leeward side of the branches and areas where they are mutually obstructed receive almost no effective wind pressure, resulting in missed harvesting. Summary of the Invention

[0004] Given the following shortcomings of the existing devices in actual use: existing devices generally use constant wind speed or simple variable frequency wind, the airflow is steady laminar flow, which is insufficient for the instantaneous shear force on the abscission layer of wolfberry stalks, and the air duct of the device is a single straight cylinder or a simple funnel structure, with uniform distribution of outlet wind speed, which cannot form an airflow field with constantly changing direction and intensity inside the dense canopy; the leeward side of the branches and the mutually obstructed areas can hardly obtain effective wind pressure, resulting in the problem of missed harvesting, this invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a goji berry fruit blowing device, which aims to generate an instantaneous pulsating airflow and periodically open and close rotating blades to form a high-shear pulsating airflow at the air duct opening, effectively detaching the fruit from the stalk. At the same time, there is a partition plate in the middle of the blades of the lower air duct, which aims to divide the air duct into left and right channels, so that the air blown out of the lower air duct is inconsistent, forming turbulence in the picking area, thereby improving the effect of the device in blowing the fruit off.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a goji berry fruit blowing device, including a gantry frame, and cantilever beams at both ends of the gantry frame, pulse airflow generating components disposed on both sides of the gantry frame, and the pulse airflow generating components are installed above the cantilever beams; The pulse airflow generating component includes a lower end fixing plate disposed on two sets of cantilever beams on the same side of the gantry frame, a fixing side plate disposed on both sides of the top of the lower end fixing plate, a fixing end plate disposed on both ends of the top of the lower end fixing plate, wherein the two sides of the fixing end plate and the end face of the fixing side plate are connected to each other, and a fixing top frame disposed on the top of the fixing end plate and the fixing side plate.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-5 As an embodiment of the present invention, a goji berry fruit blowing device is provided. This goji berry fruit blowing device includes a gantry frame 1, and cantilever beams 2 at both ends of the gantry frame 1. Pulse airflow generating components are arranged on both sides of the gantry frame 1, and the pulse airflow generating components are installed above the cantilever beams 2. The pulse airflow generating component includes a lower end fixing plate 3 mounted on two sets of cantilever beams 2 on the same side of the gantry frame 1, a fixing side plate 19 mounted on both sides of the top of the lower end fixing plate 3, a fixing end plate 18 mounted on both ends of the top of the lower end fixing plate 3, with the two sides of the fixing end plate 18 and the end faces of the fixing side plate 19 connected to each other, and a fixing top frame 20 mounted on the top of the fixing end plate 18 and the fixing side plate 19. The mounting of the fixing side plate 19 and the fixing end plate 18 on the top of the lower end fixing plate 3 forms a cylindrical cavity.

[0020] A bearing 22 is provided at one end of the fixed end plate 18, and the bearing 22 passes through the fixed end plate 18. A stepped shaft 15 is provided between the two sets of fixed end plates 18, and both ends of the stepped shaft 15 pass through the fixed end plate 18 through the bearing 22. A welding frame 11 is provided at the top of the cantilever beam 2 on one side of the gantry frame 1.

[0021] A reducer 12 is installed at the top of the welding frame 11 near the fixed end plate 18. A motor 13 is installed at the top of the welding frame 11 away from the reducer 12. The output end of the motor 13 is connected to the input end of the reducer 12. The output end of the reducer 12 is connected to a coupling 14, and the end of the coupling 14 away from the reducer 12 is connected to the end of the stepped shaft 15.

[0022] An isolation disc 16 is fixedly sleeved on the surface of the stepped shaft 15, and the isolation disc 16 is located in the cavity formed by the two sets of fixed end plates 18 and the two sets of fixed side plates 19. Two sets of pulse blades 17 are set at both ends of the isolation disc 16. The two sets of pulse blades 17 at one end of the isolation disc 16 are installed vertically, and the two sets of pulse blades 17 at the other end of the isolation disc 16 are installed horizontally. Multiple sets of connecting holes 23 are opened on the surface of the pulse blades 17, and the connecting holes 23 penetrate the pulse blades 17. Through the setting of the connecting holes 23, when the pulse blades 17 rotate, the airflow can be compressed and passed more smoothly.

[0023] The bottom of the lower fixing plate 3 is provided with six sets of air ducts 5, and the six sets of air ducts 5 are arranged in order from high to low. The six sets of air ducts 5 on the pulse airflow generating components on both sides of the gantry frame 1 are arranged in the opposite order.

[0024] The bottom of the air duct 5 is provided with an air outlet 6. One end of the air outlet 6 on both sides of the pulse airflow generating component is provided with an air nozzle 7. The air nozzle 7 can be detachably inserted into the air outlet 6. The size of the air nozzle can be adjusted according to the actual situation to obtain the ideal airflow.

[0025] The top of the gantry frame 1 is provided with a shock-absorbing pad 10, a fan mounting bracket 8 is provided on both sides of the top of the shock-absorbing pad 10, and a fan 9 is provided on the top of the fan mounting bracket 8. Through the setting of the shock-absorbing pad 10, and the setting of the first flared fabric 4 and the second flared fabric 21 as soft fabrics, the vibration brought by the fan 9 can be absorbed and resonance can be prevented.

[0026] The top of the fixed top frame 20 is provided with a first flared fabric 4 on both sides, and a second flared fabric 21 is provided at both ends of the top of the fixed top frame 20. The two sides of the second flared fabric 21 are connected to one end of the first flared fabric 4, and the tops of the second flared fabric 21 and the first flared fabric 4 are connected to the output end of the fan 9.

[0027] During use, the device is first installed on the gantry frame 1. Then, the starting motor 13 drives the reducer 12 and coupling 14 to rotate, which in turn drives the stepped shaft 15 to rotate. This causes the two sets of pulse blades 17, which are vertically mounted at one end and horizontally mounted at the other end, to rotate in a cylindrical cavity. During the rotation of the pulse blades 17, when they rotate to be parallel to the air duct inlet of the fixed top frame 20, the air is blocked by the blades and cannot pass through the generator. The air is compressed in the housing. As the pulse blades 17 continue to rotate, the opening of the blades and the air duct gradually increases, and the air can pass through. Until the pulse blades 17 rotate to the vertical air duct inlet, the air can pass through the cylindrical cavity completely. This process is repeated. The air inlet forms a pulsating airflow under the repeated opening and closing of the pulse blades 17. The frequency of the pulsating airflow can be controlled by adjusting the speed of the motor 13 to achieve the best harvesting pulsating airflow. Then, the cylindrical cavity is divided into two chambers, left and right, by the isolation disc 16, which makes the subsequent pulsed airflow asynchronous on the left and right. The multiple sets of connecting holes 23 on the pulse blade 17 allow the airflow to be compressed and pass through more smoothly when the pulse blade 17 rotates. Simultaneously, the blower 9 can be activated to generate wind that enters the cylindrical cavity through the first flared fabric 4 and the second flared fabric 21, which are divided into two chambers by the isolation disc 16. The wind is then discharged through the air outlets 6 at the bottom of the six sets of air ducts 5 arranged from high to low at the bottom of the lower fixed plate 3. This can meet the harvesting needs of plants of different heights. Furthermore, the six sets of air ducts 5 on the pulse airflow generating components on both sides of the gantry frame 1 are arranged in opposite order, resulting in staggered winds and further turbulence, which improves the harvesting effect.
