Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree planting, in particular to an adjustable fruit tree pollination device. Background Art

[0002] Pollination is an essential process for fruit trees to bear fruit. There is usually some yellow powder in the flowers of fruit trees, which is called pollen. This pollen needs to be transferred to the flowers of the same kind of fruit trees. The process of pollen moving from the anther to the stigma is called pollination.

[0003] According to the different pollination methods of fruit tree pollen, it is divided into natural pollination and artificial assisted pollination. Among them, natural pollination includes anemophilous pollination that relies on wind to transmit pollen, entomophilous pollination that relies on insects to transmit pollen, and ornithophilous pollination that relies on birds to transmit pollen. Although anemophilous pollination, entomophilous pollination, and ornithophilous pollination can achieve the purpose of flower pollination to a certain extent, due to the interference of the external environment in anemophilous pollination, entomophilous pollination, and ornithophilous pollination, the pollination effect cannot be guaranteed, and the fruit cannot reach the expected yield. Artificial assisted pollination overcomes the defect that pollination cannot be guaranteed due to insufficient conditions, can greatly increase the pollen grains on the stigma, increase the relative total amount of hormones contained in the pollen grains, and the enzymatic reaction is also correspondingly strengthened, playing a role in promoting pollen germination and pollen tube growth, and the fertilization rate can be greatly improved, so as to achieve the expected yield.

[0004] In actual production and life, when artificially pollinating the flowers of fruit trees, pollen is usually sprayed on the flowers to be pollinated one by one through a pollen gun. Although this operation can accurately pollinate each open flower of the fruit tree, because there are many open flowers on each fruit tree, if a pollen gun is used to spray pollen one by one, it is not conducive to orchards with large-area planting and will consume a large amount of labor costs. Therefore, the emergence of a pollen automatic sprayer solves the problem of consuming a large amount of labor costs. When in use, only need to place the pollen automatic sprayer between two trees or between two rows of fruit trees, start the device, and the pollen will be ejected under the action of external force during the rotation process and spread and fall on the flower stigma to complete pollination. However, because the flowers of fruit trees grow on branches at different heights of the fruit trees, the flowers on the branches at the same height as the pollen automatic sprayer receive more pollen than the flowers on the branches at other heights, thus causing the problem of uneven pollination among different flowers on the same fruit tree and affecting the fruit tree yield.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] In order to solve the problem existing in the prior art that when using a fruit tree pollinator, pollen will be ejected under the action of external force during rotation. Since flowers grow on branches at different heights of fruit trees, the amount of pollen landing on the flowers on the branches at the same height as the nozzle is greater than that on the flowers on the branches lower than this height during rotational spraying, resulting in uneven pollination.

[0032] In order to solve the problems existing in the above prior art, the present utility model provides an adjustable fruit tree pollination device.

[0033] Referring to attached Figure 1 ~attached Figure 2 shown, the adjustable fruit tree pollination device in Embodiment 1.

[0034] Embodiment 1

[0035] As Figure 1 shown, the adjustable fruit tree pollination device includes a pollen nozzle assembly 1 and a base 2. The pollen nozzle assembly 1 is located above the base 2, and there is also an up-and-down rotation reciprocating mechanism 3 between the base 2 and the pollen nozzle assembly 1; the up-and-down rotation reciprocating mechanism 3 is connected to the pollen nozzle assembly 1 and is used to drive the pollen nozzle assembly 1 to move up and down above the base 2 while rotating, and includes: a rotation assembly 31 and a height adjuster 32. Among them, the rotation assembly 31 is arranged between the pollen nozzle assembly 1 and the base 2 and is fixedly connected to the pollen nozzle assembly 1 for driving the pollen nozzle assembly 1 to rotate; the height adjuster 32 is arranged between the rotation assembly 31 and the base 2 and is connected to the rotation assembly 31 for driving the rotation assembly 31 to move away from or close to the base 2.

[0036] Referring to the attached Figure 1 As shown, the rotating component 31 can be any structure capable of driving the pollen nozzle component 1 to rotate, and the height adjusting component 32 can be an electric push rod or an electric cylinder.

[0037] In the present utility model, the rotating component 31 in the up-and-down rotating reciprocating mechanism 3 enables the pollen nozzle component to rotate when spraying pollen. By adjusting the height of the height adjusting component 32, the pollen spraying height of the pollen nozzle component 1 can be adjusted in real time. At this time, the pollen nozzle component 1 presents a spiral upward or spiral downward above the base 2, so that the pollen sprayed by the pollen nozzle component 1 can be fully diffused in the longitudinal height and the horizontal height, enabling the flowers growing on each height branch of the fruit tree to be evenly pollinated.

[0038] Specifically, one implementation manner of the rotating component 31 is given. The rotating component 31 includes: a reversible motor 311, a sleeve 313, and two extension rods 315. Among them, the reversible motor 311 is longitudinally arranged on the base 2, and a driving gear 312 is fixedly sleeved on the rotating shaft of the reversible motor 311; the sleeve 313 is connected to the base 2 through a fixing frame, and a driven gear 314 is fixedly sleeved on the outer wall of the sleeve 313, and the driven gear 314 meshes with the driving gear 312; the two extension rods 315 are symmetrically arranged on both sides of the sleeve 313 longitudinally along the sleeve 313, and the telescopic ends of the two extension rods 315 are both on the pollen nozzle component 1, and the fixed ends of the two extension rods 315 are both fixed on the tooth disc surface of the driven gear 314 through support rods;

[0039] The telescopic end of the height adjusting component 32 penetrates through the sleeve 313 and passes out of the sleeve 313, and the passing-out end is rotatably connected to the pollen nozzle component 1.

[0040] Working principle:

[0041] Start the power control switch connected to the reversible motor 311. When the reversible motor 31 rotates forward, it drives the driving gear 312 to rotate forward. At this time, since the driven gear 314 meshes with the driving gear 312, the extension rod 315 located on the tooth disc surface of the driven gear 314 drives the pollen nozzle component 1 to rotate, and the height adjusting component 32 penetrates through the mounting sleeve 313 and is rotatably connected to the pollen nozzle component 1, and is used to change the height of the extension rod 315 and thus change the height of the rotating pollen nozzle component 1 by changing its own height.

[0042] Specifically, the specific structure of the height adjusting component 32 is given. Here, the height adjusting component 32 given is an electric cylinder. The reason for selecting the electric cylinder for the height adjusting component 32 in the present utility model is as follows:

[0043] (1) Comparing from the form of the lead screw, electric push rods mostly use ordinary trapezoidal lead screws and rolled ball screws; electric cylinders mostly use ball screws and planetary ball screws.

[0044] (2) Comparing from the form of connection with the motor, electric push rods mostly use transmissions such as gears and worm gears, with relatively low efficiency; electric cylinders mostly use direct connection with the motor through couplings or synchronous belt pulleys, with very high efficiency.

[0045] (3) Comparing from the linear speed: The speed of electric push rods is generally < 100 mm / s; the speed of electric cylinders can reach 2 m / s.

[0046] (4) Comparing from the accuracy aspect, the accuracy of AC electric push rods is between 0.1 - 0.2 mm, and the accuracy of DC electric push rods is between 1 - 2 mm; the accuracy of electric cylinders is between 0.01 - 0.02 mm.

[0047] (5) Comparing from the control method, electric push rods generally can only control two positions, namely the 0 point and the maximum stroke (even with a servo motor or a stepper motor, it can control the intermediate position, but it is very troublesome); electric cylinders can start and stop at any position.

[0048] Embodiment 2 is different from Embodiment 1, and the structures of the rotary rotating assembly 31 and the height adjusting member 32 are given.

[0049] Specifically, referring to the attached Figure 2 As shown, the height adjusting member 32 is a cam assembly. The cam assembly includes a cam 321, a rotating shaft 322, a first driving motor, a bearing plate 323, and a plurality of telescopic cylinders 324. A support frame is provided above the base 2. The rotating shaft 322 is arranged on the support frame in the horizontal direction. The cam 321 is arranged on the rotating shaft 322. The rotating shaft 322 is also connected to the first driving motor. The rotary rotating assembly 31 includes a second driving motor 316 and a rotating shaft 317. The second driving motor 316 is arranged longitudinally on the top of the bearing plate 323, and the second driving motor 316 is connected to the pollen spraying head assembly 1 through the rotating shaft 317. The bottom of the bearing plate 323 abuts against the cam 321. A plurality of telescopic cylinders 325 are respectively connected to the bottom of the bearing plate 323 and the base 2 longitudinally.

[0050] Working principle:

[0051] Start the first drive motor and the second drive motor 316. The rotation of the second drive motor 316 drives the rotation of the rotating shaft 317, which in turn drives the rotation of the pollen nozzle assembly 1. When the first drive motor rotates, it drives the rotation of the rotating shaft 322, which in turn drives the rotation of the cam 321. When the cam 321 abuts against the bearing plate 323, the cam 321 pushes the bearing plate 323 upward while multiple telescopic cylinders 324 extend, so that the second drive motor 316, the rotating shaft 317, and the pollen nozzle assembly 1 move upward. When the cam 321 does not abut against the bearing plate 323, the bearing plate 323 will move downward under the action of gravity, and at the same time, multiple telescopic cylinders 324 shorten, so that the second drive motor 316, the rotating shaft 317, and the pollen nozzle assembly 1 move downward.

[0052] Specifically, to ensure uniform force on the bearing plate 323, the number of multiple telescopic cylinders 324 is an even number, and they are symmetrically arranged on both sides of the bearing plate 323 along the center line of the bearing plate 323.

[0053] Specifically, to reduce the impact of vibration on the effect of pollen spraying, a spring is longitudinally arranged in each of the multiple telescopic cylinders 324. The top end of the spring is connected to the bearing plate 323, and the bottom end of the spring is connected to the base 2.

[0054] Specifically, referring to the attached Figure 3 As shown, the pollen nozzle assembly 1 includes a fixing plate 11, multiple nozzles 12, a pollen bin 13, and a gas supply assembly. The fixing plate 11 is connected to the rotating assembly 31. The pollen bin 13 is arranged on the fixing plate 11, and the pollen bin 13 is connected to the gas supply assembly. Multiple nozzles 12 are arranged on the fixing plate 11, and each nozzle 12 is communicated with the pollen bin 13 through a pipeline.

[0055] Specifically, to improve the pollen spraying effect and enable uniform distribution in the spraying space, the fixing plate 11 is circular, the pollen bin 13 is arranged at the center of the circle, multiple nozzles 12 are arranged on a concentric ring of the fixing plate 11 and the pollen bin 13, and the distance between adjacent two nozzles 12 is equal.

[0056] Specifically, the gas supply assembly is a pressure pump, and the pressure pump is arranged on the fixing plate 11.

[0057] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
