Description

Technical Field

[0001] The invention relates to the technical field of strawberry planting, and in particular to an automatic pollination system for factory-based strawberry production. Background Art

[0002] In the natural environment, the pollination process of strawberries is mainly completed through insect pollination and wind pollination. As a plant with both insect-pollinated and wind-pollinated characteristics, wind plays an important role in strawberry pollination. When the natural wind blows over the flowers, it causes the flowers to vibrate, prompting the anthers to release pollen, which is spread in the air with the air flow and eventually falls on the stigma of the pistil to complete pollination.

The robot consists of an autonomous mobile platform, a pneumatic micro-tilt adaptive warming pollination unit, a strawberry canopy adaptive humidification unit, and a control system. The autonomous mobile platform can realize autonomous walking across high ridges and elevated structures in the greenhouse. The pneumatic micro-tilt adaptive warming pollination unit, the plant canopy adaptive humidification unit, and the control system are all installed on the greenhouse autonomous mobile platform. Through the staggered blowing of double rows of strawberries with pneumatic micro-tilt and the adaptive humidification of the pollination row first and then heating and blowing, the low temperature, low humidity and no wind environment during the flowering and fruiting period of greenhouse strawberries can be effectively overcome, and automatic cross-pollination mobile operation can be realized, with simple structure, good adaptability and high efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The automatic pollination system of the present invention realizes automatic cleaning of the blower pipe and intelligent control of the air outlet through the linkage design of the cleaning mechanism and the reset mechanism, wherein the flap assembly of the cleaning mechanism cooperates with the trigger assembly of the reset mechanism to realize the rational use of air pressure during the cleaning process, and the pollen and dust sucked into the blower pipe are discharged in time to avoid accumulation to form ventilation obstacles or long-term accumulation and breeding of bacteria, and the hose is flushed and cleaned by high-pressure airflow, so as to further ensure the cleanliness of the air supply pipe and the growth environment of strawberries; the pollination efficiency and genetic diversity are improved by reusing the lost pollen, and the quality of the fruit is improved, and the pollen of multiple strawberries collected in the blower pipe is discharged through the cleaning port and falls with the wind, and this natural pollen recycling method not only improves the pollination success rate, but also enhances the genetic diversity, and can realize efficient pollen recycling without additional equipment or operation, thus saving costs.

[0019] 2. The cleaning mechanism of the present invention adopts the structural design of an annular groove and a flap assembly. The double-angle slide bar is driven by a stepper motor to slide in the vertical groove and the arc groove, realizing the compound movement of the flap first descending and then flipping, so that the sealing plug can be smoothly separated from the cleaning port; during the descent of the flap, the air outlet is gradually reduced to generate a high-pressure airflow to flush and clean the hose, so that the pollen or dust attached to the pipe wall is separated, thereby ensuring the cleanliness of the air supply pipeline; while cleaning the inside of the blower pipe, the lost pollen is fully utilized to make it fall on the stamens of other strawberries with the wind, thereby enhancing the genetic diversity of pollination and improving the quality of the fruit.

[0021] 4. The reset mechanism of the present invention realizes self-locking of the plunger rod by the reciprocating motion of the guide rod in the heart-shaped groove through the cooperation of the guide block and the heart-shaped groove, so that the air outlet can maintain a stable state during the cleaning process; the air outlet and the cleaning port are discharged alternately, and the discharge air pressure of the cleaning port is guaranteed without increasing the power of the blower or other equipment, and the adhesion of pollen in the tube wall is reduced by air flow disturbance, thereby purifying the air supply environment and improving the cleaning effect; the design of the heart-shaped groove enables the guide rod to reliably switch between the upper and lower end grooves, and cooperates with the action of the reset spring to ensure the stability and reliability of the switch action of the plunger rod.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] Figure 1-Figure 6 As shown in the figure, an automatic pollination system for factory-based strawberry production includes a main controller, a timing control module, a humidity sensor, a light sensor, a temperature sensor and an array pollination unit, wherein the pollination unit includes a rack 10 and a blower 12, wherein the blower 12 is connected to a blast pipe 13; a water supply pipe 14 is installed on one side of the rack 10, a plurality of cultivation troughs 11 are arranged side by side on the rack 10, a blast pipe 13 is installed above the cultivation troughs 11, and an air outlet 4 is opened at the bottom of the blast pipe 13 corresponding to the cultivation troughs 11 2. The air outlet 42 is connected to a short tube 17, and a hose 16 is sleeved on the free end of the short tube 17; a reset mechanism is fixedly provided on one side of the short tube 17, and a plunger rod 36 is slidably arranged inside the reset mechanism. The plunger rod 36 penetrates the inner wall of the short tube 17 along the radial direction and reciprocates inside the short tube 17 to control the opening and closing of the air outlet 42; a cleaning mechanism is abutted against one side of the plunger rod 36, and when the cleaning mechanism is turned on, the collected materials inside the blast tube 13 are discharged, and at the same time, the plunger rod 36 is pushed into the short tube 17 to slowly close the air outlet 42.

[0032] In the present invention, the taps of the water supply pipe 14 are installed in each cultivation trough 11, and the rack 10 is installed with a humidity sensor, a light sensor, and a temperature sensor. The main controller controls the start and stop of the water supply pipe 14 through the information transmitted by the humidity sensor. The main controller receives information from the timing control module, the humidity sensor, the light sensor, and the temperature sensor and provides feedback through the display screen. The main controller is also connected to the alarm system and remote monitoring, and the main controller controls the start and stop of the blower 12 and the motor 24.

[0033] The timing control module is configured to start the motor 24 to open the flap 23 every 4 hours, and control the motor 24 to close the flap 23 after maintaining the time for 5 minutes.

[0034] The motor 24 is a stepper motor, which can adapt to low-speed short-stroke reciprocating motion. When moving at low speed, the stepper motor has a very small risk of losing step and has good stability.

[0035] The short tube 17 is provided with a sliding hole in the radial direction, and the plunger rod 36 is slidably installed inside the sliding hole. A sealing ring is installed inside the sliding hole. The inner diameter of the short tube 17 is smaller than the diameter of the plunger rod 36. When the plunger rod 36 is fully extended into the short tube 17, the inner diameter of the short tube 17 can be blocked to realize the opening or closing of the air outlet 42.

[0036] The present invention simulates the natural pollination mechanism, uses an air blowing system to generate airflow, and combines real-time monitoring of environmental parameters such as temperature, humidity, and light to perform pollination operations under optimal conditions, thereby achieving intelligent control of the pollination process and improving efficiency.

[0037] In the present invention, air outlet holes 42 are arranged at intervals on the blower pipe 13, and a hose 16 is installed on the air outlet hole 42. Under the action of the air flow, the hose 16 swings randomly to avoid directional direct blowing, and blows toward the strawberry stamens in a soft and non-directional state, thereby promoting pollination and reducing the probability of blowing off pollen.

[0038] A cleaning mechanism is provided on one side of the air outlet 42, an annular groove 39 is provided on the cleaning mechanism corresponding to the inner wall of the blast pipe 13, and a cleaning port 40 is provided at the bottom of the annular groove 39;

[0039] When the blower 12 is in operation, air is promoted to enter the blower pipe 13. Pollen or dust inside the blower pipe 13 will gather inside the annular groove 39 and be discharged outward for cleaning by opening the cleaning port 40 at the bottom of the annular groove 39. While opening the cleaning port 40, the trigger assembly pushes the plunger rod 36 to slowly enter the short tube 17 and gradually close the air outlet 42.

[0040] The air outlet 42 is closed without increasing the power of the blower, ensuring that the cleaning port 40 has sufficient air pressure to discharge the collected materials inside the blast pipe 13; the blast pipe 13 discharges air alternately through the air outlet 42 and the cleaning port 40, disturbing the airflow inside the blast pipe 13, reducing the sticking of pollen or dust remaining on the pipe wall, increasing the collection amount of the annular groove 39, and discharging it in time, keeping the inside of the blast pipe 13 clean.

[0041] A stepper motor 24 is provided to eventually drive the plunger rod 36 to close the air outlet 42 slowly. When the air outlet 42 is closed or opened, if the air outlet diameter is smaller than the inner diameter of the air outlet 42, the pressure of the air outlet will be increased. The increased pressure blows and cleans the inner wall of the hose 16, thereby enhancing the cleaning effect of the overall blowing device.

[0042] Furthermore, the cleaning mechanism includes an annular groove 39 and a flap assembly 15. The annular groove 39 is formed on the inner wall of the blast pipe 13 and is located on one side of the air outlet 42. A cleaning port 40 is formed at the bottom of the annular groove 39. The flap assembly 15 is located outside the cleaning port 40. The flap assembly includes a first fixing ring 18 and a flap 23. The first fixing ring 18 is fixedly mounted on the outer periphery of the blast pipe 13. A connecting plate 21 is fixedly disposed at the bottom of the first fixing ring 18. Guide plates 22 are symmetrically disposed on both sides of the bottom of the connecting plate 21. A slide groove is formed in the guide plate 22. A double-angle slide bar 30 is slidingly arranged inside the slide groove, and the bottom end of the double-angle slide bar 30 is fixedly connected to the inner wall of the flap 23, and a sealing plug 41 is fixedly arranged on the inner wall of the flap 23, and the sealing plug 41 is adapted to the cleaning port 40; a motor 24 is fixedly installed on the guide plate 22 on one side, and the output end of the motor 24 is transmitted to the double-angle slide bar 30 through a connecting rod, and the double-angle slide bars 30 on both sides are connected and transmitted through a transmission rod 27; the motor 24 controls the connecting rod to drive the double-angle slide bar 30 to rotate, thereby driving the flap 23 and the sealing plug 41 to flip over to realize the closing and opening of the cleaning port 40.

[0043] In order to facilitate the description of the positional relationship, the side of the flap 23 adjacent to the blast pipe 13 is set as the inner wall, and the other side opposite to it is set as the outer wall. A sealing plug 41 is fixed on the inner wall of the flap 23. The sealing plug 41 is adapted to the size of the cleaning port 40, and the sealing plug 41 seals the cleaning port 40.

[0044] When the flap 23 of the cleaning component is opened from the closed sealing state, the flap 23 first descends a distance, and then rotates 90 degrees along the guide plate 22 to be in a vertical state. When the flap 23 descends, the trigger assembly drives the plunger rod 36 to enter the short tube 17 and slowly close the air outlet 42. In the displacement range of the flap 23 descending, the sealing plug 41 also plays a certain blocking role on the cleaning port 40. The pressure inside the blast pipe 13 is discharged through the air outlet 42. During this period, the diameter of the air outlet 42 is slowly reduced, and the air pressure discharged from the reduced air outlet is increased. The airflow with increased pressure flushes the inside of the short tube 17 and the hose 16, so that the dust or pollen stuck inside is separated, and the system is further cleaned.

[0045] The pollen collected inside the blower tube 13 includes pollen from multiple strawberry plants, which is rich in diversity. The collected pollen is discharged through the cleaning port 40, and the pollen falls with the wind and randomly falls on the stamens of strawberries from different plants, thereby increasing the probability of strawberry pollen pollinating other plants, enhancing genetic diversity, improving the quality of strawberry pollination, and further improving the pollination success rate and the quality of the fruit. No additional equipment or operation is required, and the pollination quality and genetic diversity are simultaneously improved during the cleaning of the blower tube, thereby saving costs.

[0046] Furthermore, the slide groove includes a vertical groove 25 and an arc groove 26 provided on the guide plate 22, the top of the arc groove 26 is connected to the middle of the vertical groove 25, and the bottom of the arc groove 26 is spaced apart from the bottom of the vertical groove 25 and is located in the same plane; the double-angle slide bar 30 includes a first vertical rod 31, a second vertical rod 32 and a cross bar, the bottom of the first vertical rod 31 and the top of the second vertical rod 32 are fixedly connected by the cross bar; the upper and lower ends of the first vertical rod 31 are slidably installed in the vertical groove 25 through a guide shaft, and the bottom end of the second vertical rod 32 is fixedly connected to the inner wall of the flap 23. Further, the connecting rod includes a first connecting rod 28 and a second connecting rod 29, one end of the first connecting rod 28 is fixedly installed at the output end of the motor 24, the other end of the first connecting rod 28 is rotatably connected to the second connecting rod 29, and the other end of the second connecting rod 29 is rotatably fixedly installed at the upper end of the first vertical rod 31; the top ends of the first vertical rods 31 on both sides are connected by a transmission rod 27.

[0047] Figure 3 As shown, when the motor 24 rotates, the output end of the motor 24 drives the first connecting rod 28 to rotate counterclockwise ( Figure 3 When the first vertical rod 31 moves to the bottom of the vertical groove 25, the motor 24 continues to operate and drives the second vertical rod 29 to move downward through the first connecting rod 28. At this time, the second connecting rod 29 drives the upper end of the first vertical rod 31 to slide downward in the arc groove 26 and rotate around the lower end of the first vertical rod 31 until it rotates 90 degrees. The second vertical rod 32 drives the flap 23 to rotate from a horizontal position to a vertical position. The sealing plug 41 fixed on the flap 23 is completely separated from the cleaning port 40 to realize opening.

[0048] Figure 4 As shown in FIG. 1 , when the cleaning port 40 needs to be blocked, the motor 24 is rotated in the reverse direction, and the output end of the motor 24 drives the first connecting rod 28 to rotate clockwise (refer to FIG. 1 ). Figure 4 The guide plate 22 on the right side of the middle rotates, the first connecting rod 28 pushes the second connecting rod 29 to move, the second connecting rod 29 drives the upper end of the first vertical rod 31 to slide upward in the arc groove 26 and rotate around the lower end of the first vertical rod 31 until it rotates 90 degrees, and the second vertical rod 32 drives the flap 23 to rotate from the vertical position to the horizontal position; when the motor 24 continues to run, it drives the first vertical rod 31 to move upward through the second connecting rod 29. At this time, the second vertical rod 32 drives the flap 23 to move upward, and the sealing plug 41 fixed on the flap 23 is blocked with the cleaning port to achieve closure.

[0049] Furthermore, the reset mechanism includes a guide block 37 and a trigger assembly, wherein the guide block 37 is mounted on the outside of the short tube 17 through a third fixing ring 20, and a plunger rod 36 is slidably arranged inside the guide block 37, one end of the plunger rod 36 continues to slide outward to abut against the trigger assembly, and the other end of the plunger rod 36 slides radially into the short tube 17 to block the air outlet 42; a guide groove 43 is provided on one side of the guide block 37, and a heart-shaped groove 46 is provided at one end of the guide groove 43 away from the trigger assembly, and a through-connection is formed between the guide groove 43 and the plunger rod 36, a slider 45 is fixed on the plunger rod 36, and the slider 45 is slidably mounted inside the guide groove 43, and a reset spring 44 is installed between the slider 45 and the inner wall of the guide groove 43; a swing rod 38 is installed on the slider 45 through a rotating shaft, and a guide rod 47 is installed on the other end of the swing rod 38, and the guide rod 47 extends into the heart-shaped groove 46 for sliding guidance;

[0050] The trigger assembly includes a double-headed fork rod 33 and a second fixed ring 19, the second fixed ring 19 is installed on the outside of the blower pipe 13, a hinged seat is set at the bottom of the second fixed ring 19, the double-headed fork rod 33 is hingedly installed in the hinged seat, and the first rotating wheel 34 and the second rotating wheel 35 are respectively installed at both ends of the double-headed fork rod 33, the first rotating wheel 34 abuts the outer wall of the flap 23, and the second rotating wheel 35 abuts the end of the plunger rod 36; the hinged seat of the second fixed ring 19 deviates from the center of the double-headed fork rod 33 and is close to the first rotating wheel 34.

[0051] Figure 3 , Figure 4 and Figure 5 As shown in the figure, the hinge seat of the second fixing ring 19 is eccentrically connected to the double-headed fork rod 33. The second fixing ring 19 is closer to the first rotating wheel 34 than the second rotating wheel 35. It is in an eccentric position on the double-headed fork rod 33, and the torques at both ends are not equal, which is in an unbalanced state. When the double-headed fork rod 33 is not disturbed by external forces, one end of the second rotating wheel 35 is lower than one end of the first rotating wheel 34.

[0052] When the double-headed fork rod 33 deviates up and down, the vertical displacement of the first rotating wheel 34 is smaller than the vertical displacement of the second rotating wheel 35 , and the diameter of the second rotating wheel 35 is larger than the diameter of the first rotating wheel 34 .

[0053] When the flap 23 is in a horizontal position, Figure 3 As shown in FIG. 1 , the top end of the first rotating wheel 34 abuts against the outer wall of the flap 23 , while the top end of the second rotating wheel 35 abuts against the bottom of the outer end of the plunger rod 36 , and is in a stable state.

[0054] In the present invention, the flap 23 descends to drive the first rotating wheel 34 to produce a smaller offset which is converted into a larger offset on the second rotating wheel 35, thereby achieving a large movement of the second rotating wheel 35 and then causing a larger reciprocating displacement of the plunger rod 36, and finally completing the opening and closing of the air outlet 42 by the plunger rod 36.

[0055] When the flap 23 is in the vertical position, Figure 4 As shown in the figure, since the torque at one end of the second wheel 35 is greater than the torque at one end of the first wheel 34, the second wheel 35 is in a natural drooping state; when the flap 23 descends and flips, one end of the first wheel 34 is pressed down, and one end of the second wheel 35 is lifted up and lifted to the upper part of the plunger rod 36 to form a stable state.

[0056] Figure 6 As shown in , when the guide rod 47 is located in the lower end groove of the heart-shaped groove 38, the plunger rod 36 is squeezed by the second rotating wheel 35 and moves toward the guide block 37, the slider 45 is driven to compress the reset spring 44 and move forward, driving the swing rod 38 and the guide rod 47 at the end to abut and slide in the heart-shaped groove 46; the guide rod 47 slides from the adjacent side to the upper end groove, and when the external force on the plunger rod 36 is released, the guide rod 47 falls back to the bottom of the upper end groove of the heart-shaped groove 46 under the operation of the reset spring, forming a locked state, at which time the plunger rod 36 extends into the short tube 17 to block the air outlet;

[0057] When the plunger rod 36 is squeezed by the second rotating wheel 35 again, the guide rod 47 moves toward the bottom of the other side of the upper end groove. When the external force on the guide rod 47 is released, under the action of the reset spring 44, the guide rod 47 slides from the adjacent side back to the lower end groove of the heart-shaped groove 38, and at the same time drives the plunger rod 36 to move out of the short tube 17, thereby opening the air outlet.

[0058] Among them, there is a distance when the guide rod 47 moves to the top of the top groove of the heart-shaped groove 46 and then falls back to the bottom of the top groove. This distance is beneficial for the second rotating wheel 35 to transfer from the lower part of the plunger rod 36 to the upper part, ensuring the basic stroke. The plunger rod 36 retracts to form an upward support for the second rotating wheel 35.

[0059] Furthermore, one end of the heart-shaped groove 46 adjacent to the reset spring 44 is set as a reference lower end, and the end away from the reset spring 44 is set as a reference upper end; the lowest point of the top wall of the lower end groove of the heart-shaped groove 46 is set as a reference center line along the straight line where the reset spring 44 moves in the direction of movement; the lowest point of the bottom wall of the lower end groove of the heart-shaped groove 46, the lowest point of the top wall of the upper end groove of the heart-shaped groove 46 and the lowest point of the bottom wall of the upper end groove of the heart-shaped groove 46 all deviate from the center line; the lowest point of the top wall of the upper end groove of the heart-shaped groove 46 and the lowest point of the bottom wall of the upper end groove are respectively located on both sides of the center line; the lowest point of the bottom wall of the lower end groove of the heart-shaped groove 46 and the lowest point of the top wall of the upper end groove of the heart-shaped groove 46 are both located on the same side of the center line.

[0060] Figure 6 As shown in , the landing points of the bottom and top of the slide grooves on both sides of the heart-shaped groove 46 are deviated from the center line, and when the guide rod 47 is pushed forward, it will move in the adjacent side slideway.

[0061] Further, the temperature sensor, humidity sensor, and light sensor (not shown in the figure) are all disposed on the shelf 10 and arranged at intervals along the length direction of the shelf 10. The sensors are electrically connected to the main controller through signal lines.

[0062] The temperature sensor, humidity sensor, and light sensor are arranged at intervals along the length direction of the shelf 10 and are electrically connected to the main controller through signal lines, so as to monitor the temperature, humidity, and light parameters of the factory strawberry production environment in real time, provide accurate environmental data for the main controller, and thus perform the pollination operation under the best environmental conditions, improving the pollination efficiency and success rate.

[0063] Furthermore, the hose 16 is made of a flexible material. One end of the hose 16 is fixedly connected to the short pipe 17, and the other end is in a flared shape.

[0064] The hose 16 is made of a flexible material and has a flared design at one end. It can be made of silicone material and can swing randomly under the action of the air outlet airflow, avoiding direct blowing in a fixed direction, and blowing towards the strawberry stamens in a soft and non-directional state, which can not only promote the effective spread of pollen but also reduce the probability of strong airflow directly blowing off the pollen, thereby improving the success rate of pollination.

[0065] Further, the cross-section of the cultivation trough 11 is in a "U" shape. A plurality of positioning protrusions for fixing the plants are provided on the inner wall of the cultivation trough 11. The positioning protrusions are evenly distributed along the inner wall of the cultivation trough 11, and drain holes are provided at the bottom of the cultivation trough 11.

[0066] The cultivation trough 11 is designed in a "U" shape and has evenly distributed positioning protrusions on the inner wall, which can effectively fix the growth position of the strawberry plants, prevent the plants from toppling or shifting. At the same time, the drain holes at the bottom can timely drain the excess water, avoiding the plant roots from being soaked, providing a stable and well-ventilated growth environment for the strawberry plants, and being beneficial to the healthy growth and flowering and fruiting of the plants.

[0067] Working principle:

[0068] Working principle of the cleaning component:

[0069] When the motor 24 rotates, through the transmission of the first connecting rod 28 and the second connecting rod 29, the double-folded angle slide rod 30 moves in the vertical groove 25 and the arc groove 26; during the process of the flap 23 changing from the closed and sealed state to the open state, it first descends a certain distance, and then rotates 90 degrees around the guide plate 22 to be in a vertical state. During the descent of the flap 23, the sealing plug 41 will also play a certain role in blocking the cleaning port 40. At this time, the pressure inside the air duct 13 is discharged through the air outlet holes 42.

[0070] Working principle of the reset component:

[0071] When the flap 23 descends, it drives the first rotating wheel 34 to produce a smaller offset, which is converted into a larger offset on the second rotating wheel 35; the movement of the second rotating wheel 35 pushes the plunger rod 36 to slide in the guide block 37, thereby controlling the opening and closing of the air outlet 42; a guide groove 43 is provided on one side of the guide block 37, and a heart-shaped groove 46 is provided at the far end; the slider 45 fixed on the plunger rod 36 slides in the guide groove 43, and drives the guide rod 47 to move in the heart-shaped groove 46 through the rocker rod 38, thereby realizing the self-locking function of the plunger rod 36.

[0072] When the guide rod 47 is located in the lower end groove of the heart-shaped groove 46, the plunger rod 36 is squeezed by the second rotating wheel 35 to move toward the guide block 37, driving the slider 45 to compress the reset spring 44; the guide rod 47 slides from one side to the upper end groove, and when the external force is released, under the action of the reset spring 44, the guide rod 47 falls back to the bottom end of the upper end groove of the heart-shaped groove 46, forming a self-locking, and at this time the plunger rod 36 extends into the short tube 17 to block the air outlet 42; when the plunger rod 36 is squeezed again, the guide rod 47 moves to the other side, and after the external force is released, it returns to the lower end groove under the action of the reset spring 44, driving the plunger rod 36 to move out of the short tube 17, thereby opening the air outlet 42.
