Description

Technical Field

[0001] This utility model relates to the field of longan pollination technology, and in particular to a pollination and rain-avoidance device for longan flower spikes. Background Technology

[0002] Longan originated in southern my country and is adapted to tropical and subtropical climates. Because its flowering period is subject to strict meteorological conditions, it is prone to adverse weather such as continuous rainfall, which can cause the anthers to fail to dehisce, hindering pollination and fertilization, and even causing flower rot and reducing fruit set. Therefore, a pollination and rain protection device for longan flower spikes is set up to provide targeted rain protection for the flower spikes, keep the pollen dry and viable, create a suitable pollination environment, ensure the smooth progress of the pollination process, reduce damage to the flower spikes, and improve the pollination success rate and fruit yield of longan.

[0003] A search revealed Chinese patent publication number CN218571016U, which discloses a rain-sheltered pollination device for longan flower spikes. The device includes an extension support frame, a lifting rod fixedly mounted on the upper middle part of the frame, and an extension canopy roof fixedly connected to the end of the lifting rod furthest from the frame. A vertical rod is slidably connected to the outer side of the frame and fixedly connected to the top of the canopy. A deflector baffle is rotatably connected to the upper part of the vertical rod, and a control unit for controlling the rotation of the deflector baffle is fixedly mounted on the vertical rod. In this invention, the extension support frame can fully extend the rain-sheltered cloth. Because the cloth is lightweight, no additional support is needed in the middle, effectively increasing the internal space of the rain-sheltered device and preventing excessive support rods from scratching the longan plant's branches, leaves, and flower spikes. The rain-sheltered device completely covers the longan plant, ensuring rain protection during rainy days. It can also be quickly retracted when the rain stops, improving the device's flexibility and practicality.

[0004] The aforementioned patent has the following shortcomings: Since the rain cover of the existing device is a rigid coated cloth or a flexible amorphous cloth, it needs to be manually folded when stored, which is cumbersome, time-consuming and labor-intensive. Moreover, there is no fixed constraint after folding, which easily leads to loosening and tangling, occupying transportation and storage space. At the same time, repeated disassembly and folding can easily cause the edges of the rain cover to tear and the coating to fall off, shortening the service life of the device.

[0005] Therefore, a pollination and rain protection device for longan flower spikes is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide a pollination and rain protection device for longan flower spikes to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] Example 1:

[0038] like Figures 1 to 6 As shown, a pollination and rain protection device for longan flower spikes includes a support frame 1, and further includes:

[0039] The inner rod 4 is inserted into the top of the support frame 1. Connecting plates 6 are fixed on both sides of the top of the inner rod 4. A mounting shell 7 is fixed on one side of the connecting plate 6. A connecting frame 5 is fixed on one side of the support frame 1.

[0040] Storage structure 8 is provided on the other side of connecting plate 6. Storage structure 8 includes storage shell 801 fixed on the other side of connecting plate 6. The storage shell 801 has an inlet and outlet 802 on the side away from connecting plate 6. A winding roller 804 is rotatably connected inside the storage shell 801. Locking components are provided on both sides of the winding roller 804.

[0041] Rainproof cloth 9 is wrapped around the outside of take-up roller 804, and one end of rainproof cloth 9 is fixed with mounting plate 10 which is plugged into mounting housing 7;

[0042] The lifting structure 3, used to push the inner rod 4 up and down, is set at the top of one side of the support frame 1;

[0043] The support structure 2, which is used to provide auxiliary support for the support frame 1, is set on both sides of the bottom end of the support frame 1.

[0044] In this embodiment, the two sets of devices are first erected on both sides of the longan tree and arranged in a coordinated manner. The mounting plate 10 of one set of devices is inserted into the mounting shell 7 of the other set of devices to achieve splicing, so that the rainproof cloth 9 is unfolded to protect the longan tree from rain. The height of the rainproof cloth 9 can be adjusted according to the height of the longan tree using the lifting structure 3.

[0045] like Figures 1 to 4As shown, the locking assembly includes a crank 803 fixed to one side of the take-up roller 804, a threaded sleeve 807 fixedly connected to the housing 801 on the other side of the take-up roller 804, a clamping plate 808 fixed to one side of the threaded sleeve 807, a locking sleeve 806 threadedly connected to the outer side of the threaded sleeve 807, the clamping plates 808 are arranged in a ring at equal intervals on one side of the threaded sleeve 807, and the top view cross-section of the inner side of the locking sleeve 806 is a funnel-shaped inclined structure. A cleaning brush 805 is fixed inside the inlet and outlet 802, and the cleaning brush 805 is symmetrically distributed on the horizontal center line of the inlet and outlet 802.

[0046] In this embodiment, when rain protection is required, first loosen the locking sleeve 806 to release the lock on the take-up roller 804, pull the rainproof cloth 9 out from the inlet / outlet 802, then insert the mounting plate 10 into the mounting housing 7 to fix the rainproof cloth 9, and tighten the locking sleeve 806 to squeeze the clamping plate 808, thereby locking the take-up roller 804, keeping the rainproof cloth 9 flat and realizing the rain protection function. When rain protection is not needed, turn the crank 803 in the opposite direction to drive the take-up roller 804 to roll up the rainproof cloth 9, tighten the locking sleeve 806 to squeeze the clamping plate 808 to fix the take-up roller 804, which to a certain extent avoids the rainproof cloth 9 from becoming loose and tangled, and extends its service life.

[0047] Example 2:

[0048] A pollination and rain-protection device for longan flower spikes is described in this embodiment, which is an improvement upon Embodiment 1, as follows: Figures 1 to 6 As shown, the lifting structure 3 includes a protective shell 301 fixed to the top of one side of the support frame 1. A worm gear 302 is rotatably connected to one side of the inside of the protective shell 301. A worm 306 meshing with the worm gear 302 is rotatably connected to the top of the inside of the protective shell 301. A handle 303 is fixed to one side of the worm 306. A gear 304 connected to the worm gear 302 is rotatably connected to the other side of the inside of the protective shell 301. A rack 305 meshing with the gear 304 is fixed to one side of the inside of the inner rod 4. The gear 304 passes through the support frame 1 and extends into the inside of the inner rod 4 to contact the rack 305. The rotating end of the worm gear 302 is connected to the rotating end of the gear 304.

[0049] In this embodiment, when the height of the device needs to be adjusted, the worm 306 is rotated by turning the handle 303, so that the worm 306 meshes with the worm wheel 302, thereby driving the gear 304 to rotate. The gear 304 meshes with the rack 305, thereby pushing the inner rod 4 to rise and fall along the support frame 1, so that the height of the device is adapted to the growth needs of the flower spike, which to a certain extent ensures the rain protection effect of the flower spike at different stages, while reserving suitable space for field management operations.

[0050] like Figures 1 to 5As shown, the support structure 2 includes a movable sleeve 205 slidably connected to the bottom of the outer side of the support frame 1. A hand-tightening bolt 206 is threadedly connected to one side of the movable sleeve 205. Support arms 204 are rotatably connected to both sides of the movable sleeve 205. A support plate 202 is fixed to the bottom of the support arm 204. An anchor rod 201 is threadedly connected to the inside of the support plate 202. A guide arm 203 is rotatably connected to one side of the inside of the support arm 204. The side of the guide arm 203 away from the support arm 204 forms a rotating structure with the support frame 1 through a pin. The support arms 204 are symmetrically distributed on the vertical center line of the support frame 1.

[0051] In this embodiment, the position of the movable sleeve 205 on the support frame 1 is adjusted by loosening the hand-tightening bolt 206. Then, the movable sleeve 205 pushes the support arm 204 to unfold. At the same time, the guide arm 203 adjusts the support angle in sync, so that the support plate 202 is in contact with the ground. Then, the anchor rod 201 is screwed into the ground to fix it, thereby enhancing the anti-tipping ability of the support frame 1 and resisting the impact of external forces such as wind and rain to a certain extent.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
