Ear scissors suitable for ear cutting treatment of weeds in crop field

Abstract

The utility model discloses spike shears suitable for spike shearing treatment of weeds in a crop field. The spike shears comprise a shear head, a shear shaft, a spring, shear handles, a hand protection sleeve and a lock catch. The cutting edge of the shear head adopts a sawtooth design to prevent the sliding of weed stalks, and the shear tip adopts a large-head baffle design to prevent the weed stalks from sliding out of the spike shear and prevent the shear tip from puncturing a human body or other objects; the scissors handle adopts a grab handle design, so that long-time continuous ear cutting operation is facilitated without hurting finger backs; after weeds in a crop field head, spike shears are adopted to directly cut off spica of the weeds, mature seeds are prevented from being generated, updating and accumulation of a weed seed bank in soil are further blocked, the cardinal number of weed seedling emergence in crop planting in the next season is greatly reduced, and then the dosage of herbicide is effectively reduced. The spike shears are low in cost, suitable for efficiently and continuously carrying out weed spike shearing prevention and control operation, suitable for an automatic weeding machine and wide in application prospect.

Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a shearing tool suitable for cutting weeds in crop fields. Background Technology

[0002] Weeds remain the most damaging biological threat to crop fields. The use of chemical herbicides in major crops such as rice, wheat, and corn remains high. Seeds are the primary source of weed infestations in crop fields; a single weed plant can produce hundreds to tens of thousands of mature seeds, which continuously fall into the field, renewing and accumulating in the soil seed bank. Considering the risks of crop damage and pesticide residues in agricultural products, herbicides are generally not used for weed control in the mid-to-late stages of crop growth. Therefore, farmers often neglect weed control in the mid-to-late stages of crop growth. Extensive scientific research and production practice have proven that cutting off the inflorescence (spike) of weeds after they have headed but before the seeds mature can effectively prevent the production of mature seeds and their entry into the soil seed bank, reducing the initial number of weeds in the next crop season. This spikelet cutting is being adopted by more and more growers, and with the rapid advancement of agricultural mechanization and intelligentization, it is expected to be compatible with intelligent weeding machinery, forming an efficient, green, safe, and widely applicable weeding model, thereby significantly reducing herbicide usage.

[0003] General-purpose scissors are not suitable for pruning crop ears in the field for the following reasons: 1) Prolonged and continuous use of general-purpose scissors can cause abrasions to the backs of the fingers from the scissor handles. Even with gloves, the protection is limited and it is difficult to prevent abrasions to the backs of the fingers; 2) Because the blades of the scissors are smooth, it is necessary to grasp and hold the ear of ears to be cut during the pruning process, which adds extra movement and significantly reduces labor efficiency. Especially when walking in densely populated fields, pruning with one hand can greatly improve work efficiency; 3) General-purpose scissors lack hand protection design. In the later stages of crop growth in the field, the plants are usually closed in, the field humidity is high, the stems and leaves are dense, and there are many insects such as mosquitoes and spiders in the field. All of these environmental factors can lead to hand injuries. Utility Model Content

[0017] like Figure 1As shown, a shearing tool suitable for cutting weeds in crop fields includes a shear head 1, a shear shaft 2, a spring 3, a shear handle 4, a protective glove 5, and a locking buckle 6. The length of the shear head 1 is 1.5 to 2.5 times that of the shear handle 4. The protective glove 5 can be made of waterproof and durable materials such as leather, waterproof cloth, or soft glass. One end is fixed to the shear shaft 5, and the other end is open so that the hand can reach in and hold the shear handle 4. The shear handle 4 includes a first shear handle 41 and a second shear handle 42. A spring 3 is provided between the first shear handle 41 and the second shear handle 42. A locking buckle 6 is added to the end of the second shear handle 42 so that the tip of the shear can be closed when the shearing tool is not in use. One side of the first shear handle 41 is wavy, and a locking slot 44 is provided at the lower end of the first shear handle 41. The second shear handle 42 is arched.

[0018] The shear head 1 includes a smooth shear blade 13 and a serrated shear blade 12. The smooth shear blade 13 has a cutting edge 14 on its inner side. The height and width of the serrations on the cutting edge 14 are preferably designed to effectively prevent the target weed spikes from sliding. The height of a single serration on the cutting edge 14 is 1-4 mm and the width is 2-5 mm. It is suitable for cutting common grass weeds in rice and wheat fields.

[0019] Before use, grasp the shears handle (4) with your four fingers, hold the first shear handle 41 with its wavy shape, and use your thumb and the base of your thumb to hold the slightly arched second shear handle 42 without going beyond the raised edge 43 above the second shear handle 42. Put on protective gloves 5. In crop fields, weeds often grow in clumps or have multiple branches forming clumps. Hold the shears and move to the front of the weed clumps, open the shear head 1 and aim it at a suitable height for the weed inflorescence spikes to be cut. You can use the baffle-shaped shear head 11 at the top to separate the weed spikes from the crop plants. Lock the spikes with the two shear blades, with the serrated shear blade 12 at the bottom and the smooth shear blade 13 at the top. Then hold the shears tightly and cut the weed spikes. After that, continue to move forward and repeat the cutting operation.
