Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and specifically to a blueberry picking and preservation device and a preservation method. Background Technique

[0002] Blueberries are a type of small berry. Their fruits are blue in color, with a beautiful color, delicate pulp, a sweet and sour taste, and a pleasant aroma, making them excellent fresh food. The edible rate of blueberry fruits is 100%, and they contain rich nutritional components. In addition, they have the advantage of high antioxidant activity. Therefore, blueberries have functions such as preventing brain nerve aging, protecting eyesight, strengthening the heart, anti-cancer, softening blood vessels, and enhancing the body's immunity. Since blueberries are rich in anthocyanins, they have the effect of activating the retina, can strengthen eyesight, prevent eye fatigue, and prevent myopia.

[0003] In the prior art, the Chinese patent document with the patent number CN218483684U proposed a post-harvest cooling and preservation device for blueberries, including a box body. A sliding rod is arranged at the top of the inner cavity of the box body. A slider is slidably connected to the outside of the sliding rod. A sieve frame is arranged at the top of the slider. A first spring is arranged on one side of the inner wall of the box body where the sieve frame is located. A second spring extending to the outside of the box body is arranged at the bottom of the slider. A collection tank is arranged at the bottom of the inner wall of the box body where the sliding rod is located. The low-temperature cooling water in the water tank enters the inside of the nozzle through the drain pipe, and then the nozzle discharges the water onto the cotton cloth, which is beneficial to wet the cotton cloth. Then the motor drives two groups of screws to rotate. Since the threads of the two groups of screws are opposite, the two moving blocks move in opposite directions, and the stacked cotton cloth is stretched and attached to the bottom of the steel plate. By this method, the steel plate is cooled to achieve the cooling preservation of blueberries. However, in the actual use process, the cooling preservation of blueberries is not conducive to contact with water. Blueberries are extremely prone to spoilage after coming into contact with water, which makes subsequent processing and preservation more difficult. At the same time, when preserving the picked blueberries, usually a certain number of blueberries are collected and then cooled and preserved uniformly. The above technical solution cannot solve the problem of cooling preservation during the process of blueberry picking and collection. Therefore, the present application discloses a blueberry picking and preservation device and a preservation method to meet the requirements of improving the collection effect and preservation effect during the blueberry picking process.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a blueberry picking and preservation device and a preservation method, which have the following beneficial effects:

[0024] 1. For the blueberry picking and preservation device and the preservation method, when picking blueberries, by using the picking device to shake the branches and leaves of the blueberry, the ripe blueberries are detached from the branches due to the shaking. At the same time, by moving the positions of the moving legs and the collection rack, different picking positions can be adapted, so that the fallen blueberries enter the collection plate. Due to the semi-circular structure of the collection plate and the top surface of the collection plate being a composite woven material, the impact intensity when the fallen blueberries drop can be reduced, thereby reducing the damage caused by collisions during blueberry picking, and improving the picking efficiency.

[0025] 2. For the blueberry picking and preservation device and the preservation method, after a single blueberry picking is completed, by sliding the moving legs and the collection rack in contact with the through groove, the discharge port is brought into contact with the trigger rod, so that the baffle plate is opened. At the same time, by rotating the rotating wheel, the rotating shaft can be driven to rotate. Then, when the rotating shaft rotates, the guide groove can rotate synchronously. When the guide groove rotates, the guide rod can move along the track of the guide groove, and at the same time drive the knocking rod to deflect around the axis of the fixed seat, so that the knocking block contacts the bottom of the collection plate. Since the bottom of the collection plate is made of plastic material, the collection plate vibrates, and the blueberries on the surface of the collection plate all enter the discharge port through the through port, thus completing the transfer of the picked and collected blueberries, effectively improving the temporary transfer efficiency during the blueberry picking process, ensuring the freshness during the blueberry picking process, reducing the damage rate of blueberries during the picking process, and improving the picking effect.

[0026] 3. For the blueberry picking and preservation device and the preservation method, when the blueberries enter the storage box, the driving motor is started, so that the driving rod drives the crank to rotate synchronously, and then the connecting rod drives the bearing plate to vibrate under the drive of the buffer frame, and the blueberries falling onto the screening plate vibrate synchronously. Through the screening effect of the screening plate, the blueberries with larger volume can be discharged through the first material separation port, and the blueberries with smaller volume can be discharged through the second material separation port. Finally, the screened blueberries enter the corresponding centralized box, thereby realizing the screening of the size of the blueberries during the process of picking and transferring the blueberries, reducing the damage to the blueberries caused by subsequent classification, and effectively improving the integrity of the blueberries.

[0027] 4. The blueberry picking and preservation equipment and preservation method. The collection rack slides in the through groove. At the same time, a driving plate meshing with the synchronous teeth is provided on the inner wall of one side of the collection rack, thereby driving the synchronous teeth to rotate around the axis of the deflection rod. When the synchronous teeth rotate, the sliding arm can drive the limiting rod to rotate around the axis of the fixed rod. When the limiting rod rotates, the rotating disk can drive the limiting plate to rotate around the axis of the fixed rod. When the limiting plate rotates, the contact area with the inner wall of the air outlet can be changed. Thus, under the condition that the total air volume of the fan remains unchanged, the ventilation area of the air outlet is changed, so that the air flow speed in the storage box is increased, thereby improving the ventilation efficiency of the newly entered blueberries in the storage box. At the same time, it is ensured that the temperature of the storage box will not change greatly with the temperature of the newly added blueberries, thereby reducing the damage caused by large fluctuations in temperature difference in a short time for blueberries, effectively improving the preservation effect and fruit integrity when blueberries are picked and stored.

[0028] 5. The blueberry picking and preservation equipment and preservation method. The above blueberry picking method helps to ensure the integrity and freshness of the fruits: pick during cool periods, pick gently to avoid damage, collect in time and store properly in the refrigerator. These steps not only extend the preservation time of blueberries, but also retain their best taste and nutritional value. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a blueberry picking and preservation device and a preservation method.

[0041] In a typical embodiment of the present application, as Figures 1 - 9As shown in the figure, a blueberry picking and preservation device includes a support frame 1. At the top of the support frame 1, there is a storage box 2. A cover plate 3 is fixedly connected to the top of the storage box 2. One end of the storage box 2 is provided with an air inlet 6. One end of the air inlet 6 is fixedly connected to a fan 7. The fan 7 is driven by an external power supply. An air outlet 8 is opened at the other end of the storage box 2. A through groove 40 is opened on one side of the storage box 2. A collection component is slidably connected in the through groove 40. A screening component is provided on the inner wall of the storage box 2. A control component is provided in the air outlet 8. The collection component is used for collecting and transferring the picked blueberries. The screening component is used for screening the blueberries before preservation after picking. The control component is used for adjusting the air volume in the storage box 2. When picking and preserving blueberries, fresh air is conveyed into the storage box 2 through the air inlet 6 by the fan 7 to maintain the appropriate humidity and temperature of the internal environment. At the same time, the screening component in the storage box 2 screens the picked blueberries to separate the blueberries that do not meet the quality requirements. The control component adjusts the air volume in the air outlet 8 to ensure that the blueberries always maintain good freshness and quality during the screening and collection processes, thereby realizing the effective preservation and management of blueberries after picking. During this process, the collection component on the through groove 40 is responsible for collecting and transferring the picked blueberries, thereby improving the collection effect and preservation effect during the blueberry picking process.

[0042] As a preferred implementation manner in this embodiment, refer to the attached Figures 1 - 6 , the collection component includes multiple groups of moving legs 9 slidably connected in the through groove 40. A collection frame 10 is fixedly connected to the moving legs 9. A collection plate 11 is provided on the top of the collection frame 10. The collection plate 11 has a semi-circular structure. A through hole 12 is opened in the collection plate 11. An outlet 13 is opened at one end of the collection frame 10. The through hole 12 and the outlet 13 are communicated through a partition. The top surface of the collection plate 11 is a composite woven material, and the bottom of the collection plate 11 is made of plastic. A fixed frame 20 is fixedly connected to one side of the collection frame 10. A rotating wheel 21 is rotatably connected to the fixed frame 20. The bottom of the inner wall of the collection frame 10 is rotatably connected to a rotating shaft 14. The bottom of the rotating shaft 14 is connected to the rotating wheel 21 through a transmission chain. A guiding groove 15 is opened on the rotating shaft 14. The guiding groove 15 has a curved arc structure. Multiple groups of fixed seats 16 are fixedly connected to the bottom of the inner wall of the through hole 12. A knocking rod 17 is rotatably connected to the top of the fixed seat 16. One end of the knocking rod 17 is fixedly connected to a guiding rod 18. One end of the guiding rod 18 is slidably connected in the guiding groove 15. The top of the other end of the knocking rod 17 is fixedly connected to a knocking block 19. The knocking block 19 is an arc protruding to one side, and the knocking block 19 can contact the bottom of the collection plate 11. A shielding plate is rotatably connected in the outlet 13. A triggering rod 39 is fixedly connected to one side inner wall of the storage box 2. The shielding plate contacts the triggering rod 39.

[0043] When picking blueberries, the branches and leaves of blueberry plants are shaken by using picking equipment. This is prior art and will not be elaborated here. As a result, the ripe blueberries are detached from the branches due to the shaking. At the same time, by moving the position of the movable support leg 9 and the collection rack 10, it can be adapted to pick blueberries at different positions, improving the scope of use. The fallen blueberries enter the collection plate 11 at the top of the collection rack 10. Since the collection plate 11 has a semi-circular structure, the blueberries falling into the collection plate 11 will all fall to the lowest point of the collection plate 11 under the influence of gravity, achieving the effect of centralized collection of the picked blueberries. Moreover, the top surface of the collection plate 11 is made of composite woven material, which can reduce the impact intensity when the blueberries fall, thereby reducing the damage caused by collisions during blueberry picking and improving the picking efficiency.

[0044] Also, when a single blueberry picking is completed, the movable support leg 9 and the collection rack 10 are pushed into the storage box 2 to come into contact with the through groove 40. By sliding in the through groove 40, the discharge port 13 comes into contact with the trigger rod 39, causing the shutter on the discharge port 13 to open. At the same time, by manually rotating the rotating wheel 21, the rotating shaft 14 can be driven to rotate through the transmission chain. When the rotating shaft 14 rotates, the guide groove 15 rotates synchronously. When the guide groove 15 rotates, the guide rod 18 moves along the track of the guide groove 15, and at the same time drives the knocking rod 17 to deflect around the axis of the fixed seat 16, so that the knocking block 19 comes into contact with the bottom of the collection plate 11. Since the bottom of the collection plate 11 is made of plastic, the collection plate 11 can vibrate under the knocking of the knocking block 19, and the blueberries on the surface of the collection plate 11 all enter the discharge port 13 through the through port 12, thus completing the transfer of the picked and collected blueberries, effectively improving the temporary transfer efficiency during the blueberry picking process, ensuring the freshness during the blueberry picking process, reducing the damage rate of blueberries during the picking process, and improving the picking effect.

[0045] As a preferred implementation in this embodiment, refer to the appendix Figure 2 、 Figure 7 and Figure 8, the screening assembly includes a connecting frame 22 fixedly connected to the inner wall of the storage box 2. On both sides of the connecting frame 22, a plurality of buffer frames 23 are fixedly connected. On one side of the buffer frame 23, a screening plate 24 is fixedly connected. On the top of the screening plate 24, an intercepting plate 25 is fixedly connected. At one end of the screening plate 24, a first material distribution port 26 is provided. At the bottom of the screening plate 24, a receiving plate is fixedly connected. At one end of the receiving plate, a second material distribution port 27 is provided; A plurality of concentration boxes 4 are arranged in the storage box 2. At one end of the concentration box 4, a handle 5 is fixedly connected. The positions of the first material distribution port 26 and the second material distribution port 27 correspond to those of the concentration box 4; A connecting rod 30 is rotatably sleeved at the bottom of the receiving plate. One end of the connecting rod 30 is sleeved on a crank 29. The crank 29 is fixedly connected to a driving rod 28. The driving rod 28 is rotatably connected to the connecting frame 22. One end of the driving rod 28 is provided with a driving motor;

[0046] When blueberries enter the storage box 2, the driving motor is started. The driving motor drives the driving rod 28 to rotate. At the same time, the driving rod 28 drives the crank 29 to rotate synchronously. When the crank 29 rotates around the driving rod 28, it can drive the connecting rod 30 to move. Further, the connecting rod 30 drives the receiving plate to vibrate. The plurality of buffer frames 23 ensure the consistency of the vibration of the receiving plate. Further, the blueberries falling onto the screening plate 24 vibrate synchronously. Through the screening effect of the screening plate 24, the blueberries with larger volume can be discharged through the first material distribution port 26, and at the same time, the blueberries with smaller volume can be discharged through the second material distribution port 27. Finally, the screened blueberries enter the corresponding concentration box 4. Thus, during the process of picking and transferring blueberries, the screening of the size of blueberries is completed, reducing the damage to blueberries caused by subsequent classification of blueberries and effectively improving the integrity of blueberries.

[0047] As a preferred implementation manner in this embodiment, refer to the attached Figure 2 and Figure 9 , the control assembly includes a support plate 31 fixedly connected to the bottom of the inner wall of the air outlet 8. The support plate 31 is in a "T" shape. A fixed rod 32 is rotatably connected to the support plate 31. A rotating disk 33 is fixedly connected to the fixed rod 32. A limiting plate 34 is fixedly connected to the top of the rotating disk 33. The limiting plate 34 is in a curved arc shape and is attached to the inner wall of the air outlet 8. A limiting rod 35 is fixedly connected to the top of the rotating disk 33. A deflecting rod 37 is fixedly connected to the support plate 31. A sliding arm 36 is rotatably sleeved on the deflecting rod 37. One end of the sliding arm 36 is slidably connected to the limiting rod 35. A synchronous tooth 38 is fixedly connected to one end of the sliding arm 36. A driving plate meshing with the synchronous tooth 38 is provided on one side inner wall of the collection rack 10;

[0048] When the collection rack 10 slides in the through groove 40, at the same time, a driving plate engaged with the synchronous gear 38 is provided on the inner wall of one side of the collection rack 10. The driving plate drives the synchronous gear 38 to rotate around the axis of the deflection rod 37. At the same time, when the synchronous gear 38 rotates, the sliding arm 36 can drive the limiting rod 35 to rotate around the axis of the fixed rod 32. When the limiting rod 35 rotates, the rotating disc 33 can be rotated. When the rotating disc 33 rotates, the limiting plate 34 can be driven to rotate around the axis of the fixed rod 32. At the same time, when the limiting plate 34 rotates, the contact area with the inner wall of the air outlet 8 can be changed. Thus, under the condition that the total air volume of the fan 7 remains unchanged, the ventilation area of the air outlet 8 is changed, so that the air flow speed in the storage box 2 is increased, and then the ventilation efficiency of the newly entered blueberries in the storage box 2 is improved. At the same time, it is ensured that the temperature of the storage box 2 will not change greatly with the temperature of the newly added blueberries, thereby reducing the damage caused by the large change in the temperature difference of the blueberries in a short time, and effectively improving the freshness preservation effect and the fruit integrity during the picking and storage of blueberries.

[0049] A blueberry picking and freshness preservation method, using the above-mentioned blueberry picking and freshness preservation equipment, includes the following steps:

[0050] S1. Select an appropriate time; the best picking time is in the morning or evening when the temperature is relatively cool, which helps to maintain the freshness of blueberries and avoid picking during the hot period of direct sunlight to prevent fruit damage or premature softening;

[0051] S2. Picking; Prepare picking tools, use the tools for picking, select the corresponding picking position by moving the collection rack 10. The dropped blueberries enter the collection plate 11 at the top of the collection rack 10. Since the collection plate 11 has a semi-circular structure, the blueberries are concentrated at the lowest part of the collection plate 11 under the action of gravity. The top surface of the collection plate 11 made of composite woven material reduces the collision intensity when the blueberries fall, reducing the damage rate;

[0052] S3. Centralized collection; Manually rotate the rotating wheel 21 to drive the rotating shaft 14 to rotate, so that the guide rod 18 moves along the guide groove 15, and then drive the knocking rod 17 to deflect around the axis of the fixed seat 16, so that the knocking block 19 contacts the bottom of the collection plate 11. The collection plate 11 vibrates under the knocking of the knocking block 19, and the blueberries enter the discharge port 13 through the through port 12. After the picking is completed, push the movable support leg 9 and the collection rack 10 into the storage box 2 so that they contact the through groove 40. If it is necessary to pick in batches, the mature fruits can be picked back multiple times on the same plant;

[0053] S4. Centralized storage: When the collection rack 10 slides in the through slot 40, the driving plate drives the synchronous gear 38 to rotate, causing the sliding arm 36 to drive the limiting rod 35 to rotate around the axis of the fixed rod 32, and the limiting plate 34 to rotate around the axis of the fixed rod 32, changing the ventilation area of the air outlet 8, adjusting the air flow rate in the storage box 2, delivering fresh air into the storage box 2 through the fan 7, maintaining an appropriate humidity and temperature, preventing the blueberries from being damaged due to temperature difference changes, and improving the preservation effect.

[0054] S5. Processing the picked blueberries: After the collection is completed, the blueberries are centrally transferred through the centralized box 4 to the corresponding cold storage for storage and sale.

[0055] The above method for picking blueberries helps to ensure the integrity and freshness of the fruits: Picking during the cool period, gently picking to avoid damage, timely collection and proper storage in the refrigerator. These steps not only extend the preservation time of blueberries, but also retain their best taste and nutritional value.

[0056] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
