Description

Technical Field

[0001] The invention relates to the technical field of jujube tree pollination, and in particular to a jujube tree rapid directional pollination device and a pollination method. Background Art

[0002] The jujube tree is a deciduous tree that can reach 10 meters in height. The crown is ovate, the bark is gray-brown, and the branches are divided into long branches, short branches, and deciduous branches. It blooms in May and June. The cymes are axillary, the flowers are small, yellow-green, and the drupes are ovate to oblong. The fruits ripen in August and September. When ripe, they are dark red. The fruit core is hard and pointed at both ends.

[0003] The flowers of existing jujube trees are small, and it is impossible to manually collect male pollen and then manually spray pollen on female flowers for pollination. Artificial pollination is usually completed by spraying jujube trees with pollination agents to increase the fruit setting rate. For small and medium-sized jujube seedlings, drones are used for spraying. The wind force generated by the drone flight is relatively strong, which will blow off the jujube flowers and cause the pollen of male flowers to be subjected to excessive impact from top to bottom and be blown to the ground, resulting in a reduction in the amount of fruit. At the same time, drones can only spray above the jujube trees and cannot fully spray the jujube trees with medicine, thereby reducing the fruit setting rate of the jujube trees. The efficiency of manual spraying is slow. At the same time, when drones spray medicine, the medicine in the medicine box is prone to precipitation, resulting in uneven fusion of the medicine, affecting the effect of pollination. Summary of the invention

[0004] The jujube flowers of existing jujube trees are relatively small and cannot be artificially pollinated. When spraying pesticides through drones, the wind generated by the drones will blow off the jujube flowers and reduce the amount of fruit. The drones cannot fully spray the pesticides on the jujube trees, thereby reducing the fruit setting rate of the jujube trees. The manual spraying efficiency is slow, and the pesticides in the drone medicine box are prone to uneven integration, which affects the effect of pollination. The present invention proposes a rapid directional pollination device and a pollination method for jujube trees.

[0020] Through the above technical scheme, the electromagnet is plugged into the groove of the lifting thread sleeve after being energized, so that the lifting thread sleeve can be limited, so that when the telescopic lifting screw rod rotates, the lifting thread sleeve drives the lifting thread sleeve to rise and fall, thereby driving the support plate to rise and fall, driving the spray nozzle to rise and fall, and adjusting the distance to the jujube tree.

[0021] Preferably, the outer surface of the support plate is rotatably connected with an adjusting threaded sleeve through a bearing, the outer surface of the adjusting threaded sleeve is threadedly connected with a pushing threaded sleeve, the outer surface of the pushing threaded sleeve is hinged to one end of the spray nozzle through a pin shaft, the outer surface of the spray nozzle is hinged with a pushing connecting rod through a pin shaft, one end of the pushing connecting rod is hinged to the outer surface of the support plate through a pin shaft, the outer surface of the rotating disk is rotatably connected with a telescopic transmission rod with a gear through a bearing, one end of the telescopic transmission rod is slidably inserted into the inner wall of the adjusting threaded sleeve, one end of the telescopic transmission rod is rotatably connected to the outer surface of the telescopic limit frame through a bearing, and one end of the telescopic transmission rod is meshed with the gear of the transmission sleeve through the transmission of the gear and the gear ring.

[0022] Through the above technical scheme, the rotation of the telescopic transmission rod can drive the adjusting threaded sleeve to rotate, and the rotation of the adjusting threaded sleeve can drive the pushing threaded sleeve to rise and fall, thereby pulling the pushing connecting rod to deflect, and then driving the spray nozzle to deflect, from a state perpendicular to the ground to a state parallel to the ground. The nozzle of the spray nozzle located above can face downward, and the nozzle of the spray nozzle located below can face upward, so that the middle jujube tree crown can be sprayed with liquid medicine, completing the work of artificial pollination and increasing the spray coverage rate. The telescopic transmission rod is retracted and retracted for easy storage.

[0023] Preferably, one ends of the multiple spray nozzles are fixedly connected through a hose, a delivery hose is fixedly installed on the outer surface of the spray nozzle located below, one end of the delivery hose passes through one end of the deflection frame and is fixedly installed with a suction water pump, the suction water pump is fixedly installed on the lower surface of the deflection frame, an expansion joint is fixedly installed on the water inlet end of the suction water pump, the inner wall of the fixed sleeve is rotatably connected with a suction pipe through a bearing, and one end of the suction pipe is fixedly connected to one end of the expansion joint.

[0024] Through the above technical solution, the liquid medicine in the mixing tank can be sucked into the delivery hose through the suction pipe by the suction water pump, and can be connected with the suction pipe by pulling the expansion joint.

[0025] The present invention provides a pollination method for a jujube tree rapid directional pollination device, comprising the following steps: S1: Add the pollination solution and water for irrigation into the mixing tank, move the mobile vehicle to the date garden, start the deflection motor, drive the deflection frame on the fixed frame to deflect, and transform the deflection frame from being parallel to the mobile vehicle to a vertical state, so that the plug-in block of the deflection frame is plugged into one end of the rotating turntable, and manually tighten one end of the suction water pump and one end of the suction pipe by rotating the expansion joint to fix one end of the suction water pump and one end of the suction pipe.

[0026] S2: According to the height of the tree crown, the positions of the two sets of spray nozzles are adjusted, and the locking sleeve is rotated downward to lock the connection between the telescopic lifting screw rod and the telescopic limit frame to prevent the telescopic lifting screw rod and the telescopic limit frame from extending and retracting by themselves. The adjustment motor on the deflection frame is started, and the transfer sleeve is lowered after the adjustment hydraulic cylinder is adjusted so that the transfer gear on the transfer sleeve can mesh with the gear of the telescopic lifting screw rod, driving the telescopic lifting screw rod to rotate. The two telescopic lifting screw rods are transmitted through the synchronous wheel and the synchronous belt, so that the two telescopic lifting screw rods rotate synchronously. After being energized, the plug-in electromagnet on the support plate can be plugged into the groove of the lifting threaded sleeve to limit the lifting threaded sleeve. The spring on the plug-in electromagnet is stretched, and the rotation of the telescopic lifting screw rod drives the support plate to rise and fall, and the spacing between the two sets of spray nozzles is adjusted so that the upper spray nozzle can be located above the crown of the jujube tree, and the lower spray nozzle is located below the crown of the jujube tree.

[0027] S3: After the transfer sleeve is pushed down by adjusting the hydraulic cylinder, the gear on the transfer sleeve can mesh with the gear of the telescopic transmission rod, driving the telescopic transmission rod to rotate, and the telescopic transmission rod drives the adjusting threaded sleeve slidably plugged therein to rotate, and the adjusting threaded sleeve drives the pushing threaded sleeve threadedly connected thereto to move, driving the pushing connecting rod to deflect, and pulling the spray nozzle to deflect, and then transforming from a state perpendicular to the ground to a state parallel to the ground. Through the suction of the suction water pump, the mixed liquid medicine can be transported into the suction pipe, enter the delivery hose through the suction pipe, and then be transported into the spray nozzle through the delivery hose, so as to spray the crown above and below the crown of the jujube tree.

[0028] S4: After the adjustment motor is started, the position of the transfer sleeve is adjusted by adjusting the hydraulic cylinder, so that the gear on the transfer sleeve can drive the rotating disk to rotate, and the rotating disk can drive the telescopic limit frame and the telescopic lifting screw to rotate, thereby driving the spray nozzle to rotate, so that the spraying is more uniform. At the same time, one end of the rotating disk passes through the deflection frame and drives the rotating turntable to rotate. The rotating turntable drives the stirring outer paddle to rotate. The driven bevel gear on the stirring outer paddle can rotate on the active bevel gear and then drive the stirring outer paddle to rotate, so as to stir the liquid in the stirring tank. At the same time, when the stirring inner paddle on the rotating turntable rotates, it can drive the lifting sleeve to be lifted and lowered on the fixed sleeve through the connecting column, thereby driving the lifting stirring paddle to be lifted and lowered, so as to fully stir the liquid in the stirring tank.

[0029] The beneficial effects of the present invention are: 1. By setting a stirring device, the liquid medicine can be fully stirred. By rotating the rotating disk and plugging the rotating disk with the rotating turntable, the driven bevel gear on the stirring outer paddle can be driven to rotate because it meshes with the active bevel gear, so that the stirring outer paddle can rotate while rotating around the active bevel gear. At the same time, the stirring outer paddle is in an inclined state, so the liquid medicine in the stirring tank can be fully stirred during rotation. The stirring inner paddle can rotate synchronously with the rotation of the rotating turntable. When the connecting column on the stirring inner paddle rotates around the lifting sleeve, the lifting sleeve has a ring-shaped serrated groove, which can drive the lifting stirring paddle to rise and fall, so that the liquid medicine in the stirring tank can be stirred. A variety of different stirring methods can fully stir the liquid medicine in the stirring tank, which solves the technical problem that the existing drone performs artificial pollination, the medicine in the drone medicine box is easy to blend unevenly, and the pollination effect is affected.

[0030] 2. By setting up a driving device, the spray nozzle can be adjusted in various ways. The transfer sleeve can be driven to rotate by adjusting the motor. The position of the transfer sleeve can be pushed and adjusted by adjusting the lifting of the hydraulic cylinder, thereby controlling the spray nozzle to rotate, lift or deflect. After the electromagnet is energized, the position of the transfer gear can be controlled, thereby driving the spray nozzle to rotate and lift and adjust the position at the same time, which is convenient for the spray nozzle to rotate and lift. At the same time, it can be folded after deflection for easy storage.

[0031] 3. By setting up a spraying device, the crown of the jujube tree can be sprayed from top and bottom. The rotation of the telescopic transmission rod can drive the adjusting threaded sleeve to rotate, and the rotation of the adjusting threaded sleeve can drive the pushing threaded sleeve to rise and fall, thereby pulling the pushing connecting rod to deflect, and then driving the spray nozzle to deflect, from a state perpendicular to the ground to a state parallel to the ground. The nozzle of the spray nozzle located above can face downward, and the nozzle of the spray nozzle located below can face upward, so that the crown of the jujube tree in the middle can be sprayed with liquid medicine. At the same time, the airflow generated by the spraying has top-to-bottom and top-to-bottom directions. The airflow under keeps the blown pollen only transferred between the tree crowns, while reducing the loss of liquid medicine, increasing the contact between liquid medicine and flowers, completing the pollen exchange between jujube flowers, increasing the pollination rate, completing the work of artificial pollination, and increasing the coverage of spraying. The telescopic transmission rod is telescopic for easy storage, which solves the problem that the jujube flowers of existing jujube trees are relatively small and cannot be artificially pollinated. When spraying medicine by drones, the wind generated by the flight of drones will blow off the jujube flowers and reduce the amount of fruit. The drones cannot fully spray the jujube trees with medicine, thereby reducing the fruit setting rate of the jujube trees, and the technical problem of slow efficiency of manual spraying.
