Description

Technical Field

[0001] This utility model relates to the field of fruit tree pollination technology, and in particular to a jackfruit tree pollination device. Background Technology

[0002] Jackfruit trees are monoecious with separate male and female flowers. Male inflorescences mostly grow on small branches at the top or in the leaf axils, are club-shaped, and have small flowers that darken in color when ripe. When flowering, the filaments elongate and extend to release white anthers, relying on wind or insects for pollination. Female inflorescences mostly grow on the trunk or main branches, are also club-shaped and slightly larger, and are deeply hidden within the spathe and stipules. When flowering, the slender style extends to the outside of the inflorescence to receive pollen. Existing fruit tree pollination devices generally automatically spray pollen prepared by fruit farmers onto the flowers, thereby increasing the number of fruit tree flowers pollinated and improving the fruit yield. However, it is currently impossible to control the amount of pollen sprayed in a single pollination, resulting in a large waste of pollen.

[0003] For example, a fruit tree pollination device disclosed in Chinese patent literature (publication number: CN218897845U) involves adding pollen into the storage tank and then activating a second brake motor. The operation of the second brake motor causes the rotating shaft to drive the second sector plate to rotate, thereby removing the obstruction effect on the pollen. The pollen then slides down from the inner wall of the storage tank into the inside of the circular tube. Then, the fruit growers can start the fan. The operation of the fan will draw in external air through the air inlet and then transport it into the interior of the vertical tube through the exhaust port and the circular tube. At the same time, the pollen will also enter the interior of the vertical tube with the airflow. Finally, the pollen will be sprayed out from the right end of the nozzle, thus achieving pollination of the fruit trees.

[0004] However, during a single pollination, once the second sector plate removes its obstruction of the pollen, the pollen enters the circular tube through its own fluidity. This can cause the amount of pollen falling into the circular tube to vary greatly, resulting in either too much pollen entering and causing waste, or too little pollination leading to insufficient pollination and thus reducing the fruit set rate. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when pollinating jackfruit trees, the amount of pollination per pollination is not precisely controlled, which easily leads to waste and reduced fruit yield.

[0027] Example

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a jackfruit tree pollination device, including a movable base 1, with a height adjustment mechanism and a quantitative pollination mechanism integrated above the movable base 1, which work together to achieve precise and quantitative pollination.

[0029] The mobile base 1 is equipped with casters with brakes, making it easy for operators to move the device flexibly in the orchard and adapt to different fruit tree spacings. The base integrates a rechargeable power supply, a 24V lithium battery pack, to power components such as the servo electric cylinder 26, servo motor 34, and blower housing 2, freeing them from cable constraints and adapting to complex orchard terrain. The push handle 314 connected to the upper end of the mobile base 1 is easy for the operator to push, and the push handle 314 is equipped with a PLC programmable controller, which is a mature technology and will not be described in detail here.

[0030] In the height adjustment mechanism, the lower end of the blower box 2 is fixed to the movable base 1 to provide a power source for airflow. The air outlet pipe 21 connected to one side, together with the variable diameter bend pipe 22, gradually changes the angle from 30° to 45° to optimize the airflow path and reduce pressure loss. The delivery hose 23 ensures a flexible connection during height adjustment to avoid airflow leakage.

[0031] The lifting block 25 fixed to the outside of the spraying bend 24 is linked with the servo electric cylinder 26 symmetrically installed on the movable base 1. When the piston rod of the electric cylinder extends and retracts, it drives the spraying bend 24 to rise and fall in the vertical direction, accurately adapting to the female flowers of different heights of jackfruit, ensuring that the distance between the nozzle and the female flower is stable at 10-20cm, and improving the pollination coverage and uniformity.

[0032] The feed square tube 3 of the quantitative pollination mechanism is fixed to the movable base 1 by symmetrical support rods 31 to ensure structural stability. The arc-shaped fitting grooves 32 on its front and rear inner walls are adapted to the curvature of the dispensing roller 37 and fit tightly with the dispensing roller 37 to prevent pollen leakage.

[0033] The servo motor 34 on the mounting plate 33 drives the rotating shaft 35 to rotate via a coupling. The rotating shaft 35 is linked to the drive pulley 36 and the distributing roller 37. The material troughs 38 symmetrically opened on the outside of the distributing roller 37 rotate 90° with the rotating shaft each time, accurately pouring the received pollen into the air outlet pipe 21 to achieve quantitative pollen supply.

[0034] The hopper 39 at the upper end of the feed square tube 3 is convenient for storing pollen. After the pollen is added, it is protected by the cover to prevent impurities from entering. The drive pulley 36 drives the driven pulley 311 through the synchronous belt 310, which drives the rotating rod 312 to rotate. The agitator rods 313 in the outer ring array of the rotating rod 312 continuously disperse the pollen to ensure that the pollen falls smoothly into the feed trough 38 and avoids jamming.

[0035] The working process of this utility model:

[0036] Step 1: Add sieved and dried pollen to hopper 39. Then, the operator moves the movable base 1 by pushing handle 314. The handle 314 is equipped with a controller, which is an existing PLC programmable controller, a mature technology, so it will not be described in detail. According to the height of the female flower of the jackfruit tree, the servo electric cylinder 26 is activated to extend, driving the lifting block 25 to raise and lower the spraying bend 24, adjusting it to a suitable pollination height so that the spraying bend 24 is aligned with the female flower.

[0037] Step 2: The controller starts the servo motor 34, and the output shaft drives the rotating shaft 35 to rotate 90 degrees via the coupling. The rotating shaft 35, in conjunction with the drive pulley 36, the distributing roller 37, and the external material trough 38 of the distributing roller 37, rotates, accurately pouring the pollen received in the upper material trough 38 into the air outlet pipe 21. The synchronous belt 310 drives the driven pulley 311, and the rotating rod 312 drives the stirring rod 313 to rotate, continuously stirring the pollen in the hopper 39 to prevent clumping. At the same time, the blower box 2 starts, generating a stable airflow through the air outlet pipe 21, the reducing bend pipe 22, and the conveying hose 23, conveying the pollen in the air outlet pipe 21 to the spraying bend pipe 24, so that the spraying bend pipe 24 is aimed at the female jackfruit flower and sprayed out. After completing a single quantitative pollination, the blower box 2 stops working and waits for the controller to start again.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
