Abstract
Description
Technical Field
[0001] This utility model relates to a pollination bag, specifically a cross-shaped snap-on insect-proof and breathable pollination bag, belonging to the field of pollination bag technology. Background Technology
[0002] Breeding bags, also known as pollination bags or isolation bags, are bags made of different materials. Their purpose is to effectively control plant pollination and ensure breeding purity. The style of breeding bags is usually designed according to the inflorescence of different plant types. The size, shape, and strength of the bags should ensure that the plants are not contaminated during seed development, preventing disease or growth disorders. The type of breeding bag varies with the size of the inflorescence.
[0003] However, most existing pollination bags have various problems. For example, in the pollination bag for artificial pollination disclosed in announcement number CN205431411U, although its structure is simple and easy to operate, and it greatly reduces the difficulty of the workers' work and improves the fruit setting rate of female flowers, in this technical solution and most current pollination bags, the existing pollination bags generally lack an effective support structure at the bag opening, which makes the bag body easy to collapse during use, thus causing unnecessary compression of the flowers. This collapse may not only damage the physiological structure of the flowers and affect the pollination effect, but may also reduce the air permeability of the bag body, further hindering the normal spread of pollen. In addition, the collapse of the bag opening will also increase the difficulty of operation and affect the efficiency of pollination. Therefore, there is an urgent need for a cross-shaped buckle insect-proof and breathable pollination bag to solve this problem. Utility Model Content
[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a cross-shaped snap-on insect-proof and breathable pollination bag.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cross-shaped snap-on insect-proof and breathable pollination bag includes a pollination bag body, a bag opening, a support mechanism, and a bag bottom. The bag opening is located at the top of the pollination bag body, the support mechanism is disposed inside the bag opening, and the bag bottom is located at the bottom of the pollination bag body.
[0007] The support mechanism includes a plastic strip A, a plastic strip B, a mounting groove, a base, a fixing ring, a limiting ring, and a limiting locking unit. The plastic strips A and B are arranged in a cross shape inside the bag opening. The mounting groove is located at the center of the bottom of the plastic strip A. The base is fixed to the top of the mounting groove. The fixing ring is fixed to the base. One end of the limiting ring is rotatably connected to the fixing ring, and the other end is connected and locked to the fixing ring through the limiting locking unit.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] like Figures 1 to 4 As shown, a cross-shaped snap-on insect-proof and breathable pollination bag includes a pollination bag body 1, a bag opening 2, a support mechanism 3, and a bag bottom 4. The bag opening 2 is located at the top of the pollination bag body 1, the support mechanism 3 is set inside the bag opening 2, and the bag bottom 4 is located at the bottom of the pollination bag body 1.
[0023] The support mechanism 3 includes a plastic strip A 31, a plastic strip B 32, an mounting groove 33, a base 34, a fixing ring 35, a limiting ring 36, and a limiting locking unit. The plastic strip A 31 and the plastic strip B 32 are arranged in a cross shape inside the bag opening 2. The mounting groove 33 is located at the bottom center of the plastic strip A 31. The base 34 is fixed to the top of the mounting groove 33. The fixing ring 35 is fixed to the base 34. One end of the limiting ring 36 is rotatably connected to the fixing ring 35, and the other end is connected and locked to the fixing ring 35 through the limiting locking unit.
[0024] The limiting and locking unit includes a ratchet 37, a locking plate 38, and an abutment end 39. The ratchet 37 is disposed on the outer wall of the limiting ring 36. One end of the locking plate 38 is fixed to the base 34. The abutment end 39 is disposed on the other end of the locking plate 38 and is perpendicular to one end of the locking plate 38. There is a gap between the abutment end 39 and the fixing ring 35. The other end of the limiting ring 36 is engaged in the gap, and the abutment end 39 abuts against the ratchet 37.
[0025] In this invention, a cross-shaped support rod is formed by combining overlapping plastic strips A 31 and B 32 to create a three-dimensional grid frame. This evenly distributes the pressure on the bag body, preventing local collapse and squeezing of the flowers. An adjustable quick-release hoop is provided at the overlap. Through the interaction between the abutting end 39 and the ratchet 37, the fixing ring 35 and the limiting ring 36 are connected and locked, enabling the rapid assembly and disassembly of plastic strips A 31 and B 32. No tools are required during operation, simplifying the field operation process and significantly improving the practicality and reliability of the pollination bag.
[0026] Example 2
[0027] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:
[0028] The locking plate 38 is made of a deformable material, and a first pull plate 310 is fixed on the side of the locking plate 38 near the abutment end 39. The first pull plate 310 and the locking plate 38 are located in the same plane, and a second pull plate 312 is fixed at the center of the outer wall of the limiting ring 36. The setting of the first pull plate 310 allows the operator to pull the locking plate 38 to partially bend it, thereby separating the abutment end 39 from the ratchet 37, and thus realizing the quick separation of the fixing ring 35 and the limiting ring 36.
[0029] A protrusion is provided between the base 34 and the first pull plate 310, and a return spring 311 is engaged between two adjacent protrusions. The elastic force of the return spring 311 enables the abutment end 39 to be firmly engaged with the ratchet 37.
[0030] The pollination bag body 1 is made of polyethylene material, white in color, with 2×2mm pores on the bag, and a length of 40cm. The bag opening 2 is 5cm wide and cubic in shape, and the bottom 4 is 4cm wide and cubic in shape. The 2×2mm design can prevent bees and pests from pollinating the flowers, but does not affect the flowers' water and air permeability, prevents the flowers from wilting, and makes it easy to observe the pollination status of the flowers with the naked eye after artificial pollination.
[0031] A wire 5 is fixed to one side of the bottom 4 of the bag. The wire 5 is about 10cm long and is wrapped with non-woven fabric. One end of the wire 5 is embedded about 3cm into the seal of the bottom 4 of the bag, and the remaining part extends out of the pollination bag body 1. The bottom 4 of the bag can be fixed to the branch through the wire 5.
[0032] Working principle: When using this pollination bag, first unfold plastic strip A 31 and plastic strip B 32 and overlap them to form a cross shape. At this time, plastic strip B 32 is placed in the ring formed by the combination of fixing ring 35 and limiting ring 36. Then, one end of limiting ring 36 passes through the gap between the abutting end 39 and the fixing ring 35, so that the abutting end 39 abuts against the ratchet 37, thereby connecting and locking the fixing ring 35 and the limiting ring 36, and fixing plastic strip A 31 and plastic strip B 32. Then, put the pollination bag body 1 through the bag bottom 4 on the outside of the flower that needs to be pollinated, then seal the bag bottom 4, and wrap the part of the wire 5 extending out of the bag body around the branch.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
