[0046] The embodiments of the present invention are described in detail below.

[0047] Example 1

[0048] See also Figure 1~Figure 4This embodiment provides a plum pollination device, including a bracket and a pollen supply mechanism 2, a rotary powdering mechanism 3 and a driving mechanism 4 installed on the bracket. The bracket supports the entire device, the pollen supply mechanism 2 is used to supply pollen to the rotary powdering mechanism 3, the rotary powdering mechanism 3 uses the centrifugal force generated by rotation to throw the pollen to the flowers, and the driving mechanism 4 is used to rotate the rotary powdering mechanism 3. The rotary powdering mechanism 3 uses the centrifugal force generated by rotation to throw the pollen to the flowers on the plum tree, and the pollen is evenly scattered and covers a large area, thereby improving the pollination efficiency.

[0049] The support includes a support rod 11 ; the support rod 11 is retractable, one end of the support rod 11 is provided with a handle for the fruit farmer to hold, and the other end is connected to the powder supply mechanism 2 .

[0050] The powder supply mechanism 2 includes a powder storage tank 21 , a transfer box 22 , a first conduit 23 , a second conduit 24 and a piston 25 .

[0051] The powder storage tank 21 is connected to the top of the transfer box 22 , and the bottom of the powder storage tank 21 is provided with a powder storage outlet.

[0052] The side wall of the transfer box 22 is connected to one end of the support rod 11; the transfer box 22 has a transfer inlet and a transfer outlet, and the transfer outlet is located above the transfer inlet.

[0053] The first conduit 23 is used to connect the powder storage outlet and the transfer inlet, and a first check valve is provided on the first conduit 23 .

[0054] The second conduit 24 is used to connect the transfer outlet and the rotary powder spreading mechanism 3 , and a second check valve is provided on the second conduit 24 .

[0055] The piston 25 is in sliding and sealing cooperation with the transfer box 22; the bottom of the piston 25 is located below the transfer inlet, and the piston 25 can move back and forth longitudinally.

[0056] During the longitudinal reciprocating movement of the piston 25, the piston 25 moves downward to form a negative pressure space 26 above the piston 25, and the pollen in the powder storage tank 21 is sucked into the negative pressure space 26 through the first conduit 23. The piston 25 moves upward to squeeze the pollen in the negative pressure space 26 into the rotary powder spreading mechanism 3 through the second conduit 24, thereby supplying pollen to the rotary powder spreading mechanism 3.

[0057] The rotary powder spreading mechanism 3 comprises a fixed sleeve 31 , a guide tube 32 and a rotary cylinder 33 .

[0058] One end of the fixing sleeve 31 is connected to the side wall of the transfer box 22 , and the other end has an extension portion 311 ; an annular groove 312 is formed on the side wall of the fixing sleeve 31 , and one end of the second conduit 24 is connected to the annular groove 312 .

[0059] The outer wall of the guide tube 32 is rotatably connected to the inner wall of the fixed sleeve 31; one end of the guide tube 32 is closed, and the other end is open and located in the rotating cylinder 33; a first through hole 321 is provided on the side wall of the guide tube 32, and the first through hole 321 is connected to the annular groove 312; the driving mechanism 4 can drive the guide tube 32 to rotate, and the guide tube 32 can drive the rotating cylinder 33 to rotate.

[0060] Both ends of the rotating cylinder 33 are closed, and one end of the rotating cylinder 33 has a T-shaped connecting piece 331, and the rotating cylinder 33 is rotatably connected to the extension portion 311 through the connecting piece 331; a second through hole 332 is provided on the side wall of the rotating cylinder 33, and the second through hole 332 is located on the right side of the guide tube 32; multiple second through holes 332 are arranged at intervals along the axial direction of the rotating cylinder 33, and multiple second through holes 332 are arranged at intervals along the circumferential direction of the rotating cylinder 33.

[0061] After the piston 25 moves upward, the pollen in the negative pressure space 26 can be squeezed into the annular groove 312 through the second conduit 24, and the pollen enters the guide tube 32 through the first through hole 321, and then enters the rotating cylinder 33; when the guide tube 32 is driven to rotate by the driving mechanism 4, the guide tube 32 drives the rotating cylinder 33 to rotate, and the rotation generates centrifugal force, which throws the pollen in the rotating cylinder 33 and scatters it to the flowers, thereby realizing the pollination of the plum tree.

[0062] In the prior art, there is a method of manually compressing gas to pressurize the gas and then spraying the pollen. However, to obtain an ideal pressurization effect, a large driving force is required to compress the gas, and it is more laborious for the user to operate. Compared with the rotary scattering method of this embodiment, the user is more prone to fatigue.

[0063] The driving mechanism 4 includes a hand wheel 41, a first bevel gear 42, a second bevel gear 43, a first transmission shaft 44 and a second transmission shaft 45 which are sequentially connected. The hand wheel 41, the first bevel gear 42, the second bevel gear 43 and the first transmission shaft 44 are installed on the support rod 11; the first bevel gear 42 is installed in the middle of the hand wheel 41 and meshes with the second bevel gear 43; the first transmission shaft 44 is retractable; one end of the second transmission shaft 45 is connected to the first transmission shaft 44, and the other end is connected to the closed end of the guide tube 32. During operation, the fruit farmer can drive the guide tube 32 and the rotating cylinder 33 to rotate by rotating the hand wheel 41.

[0064] In this embodiment, the rotation speed of the second bevel gear 43 is greater than the rotation speed of the first bevel gear 42, so that the rotation speed of the rotating cylinder 33 can be increased, generating a greater centrifugal force, thereby expanding the pollen scattering range and improving the efficiency of artificial pollination.

[0065] Example 2

[0066] See also Figure 1~Figure 4The difference between this embodiment and embodiment 1 is that this embodiment further includes a directional cover 34, which is sleeved on the outer wall of the rotating cylinder 33 and is detachably connected to the extension portion 311 by bolts or the like; a flared powder sprinkling port 341 is provided on the side wall of the directional cover 34, and during the rotation of the rotating cylinder 33, the powder sprinkling port 341 can be intermittently connected with the second through hole 332 on the rotating cylinder 33, so that pollen can be sprayed out in a direction along the powder sprinkling port 341, thereby facilitating directional and precise pollination during operation.

[0067] Example 3

[0068] See also Figure 1~Figure 4 The difference between this embodiment and embodiment 1 is that, in this embodiment, the first transmission shaft 44 and the second transmission shaft 45 are coaxially arranged, and further include a first connecting rod 46 and a second connecting rod 47.

[0069] The axes of the first connecting rod 46 and the first transmission shaft 44 are parallel to each other and do not overlap.

[0070] One end of the second connecting rod 47 is rotatably connected to the bottom of the piston 25 , and the other end is rotatably connected to the first connecting rod 46 .

[0071] In the process of rotating the first transmission shaft 44 and the rotating cylinder 33 by the hand wheel 41 , the hand wheel 41 can also drive the piston 25 to move back and forth longitudinally through the transmission of the first transmission shaft 44 , the first connecting rod 46 and the second connecting rod 47 , thereby facilitating the driving of the piston 25 .

[0072] Example 4

[0073] This embodiment is a further improvement made on the basis of Embodiment 3.

[0074] See also Figure 1~Figure 4 The sliding seal inside the rotating cylinder 33 is matched with a movable plate 35, and the movable plate 35 is sleeved on the outer wall of the end of the guide tube 32; a slide groove 313 is provided on the inner wall of the fixed sleeve 31, and the tail end of the slide groove 313 extends along the length direction of the fixed sleeve 31, and then extends in the reverse direction and is connected to the head end of the slide groove 313, forming a track for the convex block to slide in a circular manner; the convex block is arranged on the outer wall of the guide tube 32 and is slidably connected to the slide groove 313.

[0075] In order to adapt to the above solution, the second transmission shaft 45 is retractable; a third check valve is provided in the guide tube 32 ; and the width of the annular groove 312 is greater than the diameter of the first through hole 321 .

[0076] In the above scheme, when the guide tube 32 is rotated, the protrusion slides along the slide groove 313 and drives the guide tube 32 and the movable plate 35 to move back and forth laterally; when the movable plate 35 moves to the right, the movable plate 35 can push the pollen to the right, so that the pollen remaining in the rotating cylinder 33 moves to the second through hole 332 and is discharged under the rotation of the rotating cylinder 33 (see Figure 1 When the device is used, the right end of the device is tilted upward to the upper right, and a small amount of pollen will be deposited on the right side of the movable plate 35 under the action of its own weight).

[0077] In addition, when the movable plate 35 moves to the right, the movable plate 35 can squeeze out the pollen in the rotating cylinder 33 to better scatter the pollen. It can be understood that due to the presence of the second through hole 332, the movable plate 35 can be moved to the right without too much driving force.

[0078] Finally, it should be noted that the above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
