Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an easy-fold bag suitable for millet. Background Technology

[0002] In millet hybridization breeding, bagging is a crucial step in ensuring pollination purity. Since millet is a self-pollinating crop, cross-pollination requires artificial intervention. Bagging effectively prevents contamination by foreign pollen, ensuring the genetic purity of the hybrid offspring. Currently, sulfuric acid paper bags are commonly used in agricultural production. The method involves placing the paper bag over the millet, folding the flap to form two triangles, and then securing it with paper clips. However, this method is cumbersome. In the field, operators need to manually insert paper clips after folding the flap, a time-consuming and labor-intensive process, especially in large-scale fields where efficiency is extremely low. Secondly, existing bagging methods require cutting the bottom of the bag with scissors for artificial pollination. This not only increases the requirements for tool preparation but also easily damages the millet, affecting pollination results. Especially in large-scale field operations, scissor operation is inefficient, increasing labor and time costs. Utility Model Content

[0003] The present invention aims to provide an easy-folding bag suitable for millet, so as to solve the problems of cumbersome bag fixing operation and inconvenient opening in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The basic technical solution provided by this utility model is: an easy-folding bag suitable for millet, including a bag body, an opening at one end of the bag body, a bag flap at the opening end of the bag body, a deformable metal strip embedded on the inner or outer side of the bag flap, the deformable metal strip extending along the length direction of the bag flap; a pre-opening is provided at the bottom of the bag body, the pre-opening is detachably connected to the bag body, and the pre-opening is composed of a pre-cut line or an indentation line.

[0006] The principle of the basic technical solution: This utility model uses a deformable metal strip embedded on the inside or outside of the bag tongue. By utilizing the plasticity of the metal material, the bag tongue can be fixed by simple bending. A pre-opening composed of pre-cut lines or indentation lines is set at the bottom of the bag body, which can be quickly opened without tools, facilitating manual pollination operations, thereby improving the convenience and efficiency of the overall operation.

[0007] The beneficial effects of the basic technical solution are as follows: This utility model achieves rapid fixation of the bag tongue through a deformable metal strip, avoiding the cumbersome operation and easy loss problems of the traditional paperclip fixing method; at the same time, the pre-opening design at the bottom of the bag can be quickly opened without tools, reducing the difficulty of operation and the risk of accidentally damaging the millet, making it particularly suitable for large-scale field operations, significantly improving the efficiency and reliability of bagging operations, and providing more efficient technical support for millet hybrid breeding.

[0008] Preferably, the deformable metal strip is an aluminum wire, a galvanized iron wire, or a nickel-titanium shape memory alloy wire.

[0009] With the above design, the deformable metal strip has good plasticity and resilience, can be repeatedly bent without breaking, ensuring that the bag can be used multiple times and is securely fixed. At the same time, it has sufficient strength to support the bag structure and prevent deformation or detachment due to external forces during field operations.

[0010] Preferably, the deformable metal strip is covered with a protective layer, which is adhered to the bag flap.

[0011] With the above-mentioned design, the protective layer can prevent the metal strip from directly contacting the millet and causing damage, while also blocking external moisture, pesticides, and other substances from corroding the metal strip and extending the service life of the bag.

[0012] Preferably, the length of the deformable metal strip is 70%-100% of the bag flap.

[0013] The above settings ensure that the metal strip provides sufficient fixing force while avoiding excessive length that could lead to inconvenience or increased costs, thus achieving optimal cost-effectiveness.

[0014] Preferably, the pre-opening edge is provided with auxiliary markings.

[0015] With the above settings, operators can quickly identify the pre-opening position, operate accurately, and improve work efficiency.

[0016] Preferably, the pre-cut line or indentation line is any one of a straight line, a wavy line, or a serrated line.

[0017] Through the above settings, these pre-set weakening line structures can ensure that the bottom of the bag can be easily torn open during artificial pollination, while maintaining the structural integrity of the bag during transportation and use, avoiding accidental cracking due to external forces, and ensuring the reliability of the bag in field operations.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 As shown, an easy-folding bag suitable for millet includes a bag body 1, with an opening at one end and a bag tongue 2 at the opening end. A deformable metal strip is embedded on the inner or outer side of the bag tongue 2, extending along the length of the bag tongue 2. The deformable metal strip is made of aluminum wire, galvanized iron wire, or nickel-titanium shape memory alloy wire. The deformable metal strip is covered with a protective layer, which is adhered to the bag tongue 2. The length of the deformable metal strip is 70%-100% of the length of the bag tongue 2. A pre-opening 3 is provided at the bottom of the bag body 1, which is detachably connected to the bag body 1. The pre-opening 3 is composed of a pre-cut line or an indentation line, which can be any one of a straight line, a wavy line, or a serrated line. An auxiliary mark 4 is provided on the edge of the pre-opening 3.

[0025] The specific implementation process is as follows: First, align the open end of the bag with the millet to be pollinated. The operator uses their hand to open the bag and keep it open. Then, the bag tongue 2 is bent and folded around the millet stem. At this time, the embedded deformable metal strip undergoes plastic deformation, keeping the bag tongue 2 in a fixed shape, thus ensuring that the entire bag is securely placed on the millet. During artificial pollination, the auxiliary markings on the edge of the pre-opening 3 are used for quick positioning. The pre-opening 3 is then torn open along the pre-cut line or indentation line to carry out the pollination operation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
