Description

Technical Field

[0001] The utility model relates to the technical field of planting equipment, in particular to a novel low-damage membrane breaker. Background Art

[0002] At present, the cultivation of tobacco seedlings under film has become a practical new technology in tobacco production, and has played a very important role in Yunnan tobacco production. Breaking the film, digging out the seedlings, and cultivating the soil are important links in the production of tobacco seedlings under film. When the tobacco seedlings grow to a certain height, or when the leaves are close to the film, the seedlings are easily burned under the sun, so the film needs to be broken and the soil needs to be cultivated in time.

[0003] In the related art, reference can be made to the Chinese patent with the announcement number CN210695247U, which specifically discloses a new type of membrane breaker. The new type of membrane breaker includes a membrane breaker tube, a handle fixing rod, a handle, a barb rod, and a barb; the bottom of the membrane breaker tube is provided with a membrane breaker tooth; the handle fixing rod is fixed to the upper part of the membrane breaker tube; the handle is fixed to the handle fixing rod; the upper end of the barb rod is symmetrically fixed to the lower end surface of the handle fixing rod; and the barb is fixed to the bottom end of the barb rod. By arranging the barb rod and the barb, and designing the barb to be higher than the tooth surface of the film-breaking teeth, when breaking the film, the barb first pierces the film and is inserted into the soil layer below the film; at the same time, the distance between the barb and the inner wall of the film-breaking cylinder is designed to be 1-2 cm, so that the film pierced by the barb is within the film cut by the film-breaking teeth; after the film is broken by the film-breaking teeth, when the barb is raised, the barb hooks away the broken film, and does not hinder the film outside the cutting range of the film-breaking teeth. The cut film is hooked away by the barb and taken off the ground with the film-breaking cylinder, and there is no need to manually bend over to pick up the film again; the utility model has a simple structure and is easy to use, and effectively solves the problem of having to bend over again to pick up the broken film after breaking the film, and has strong practicality and value for wide promotion.

[0004] The applicant found that there were deficiencies in the use of the above-mentioned new type of film breaker: although it effectively solved the problem of having to bend down again to pick up the broken film after the film was broken, it was still inconvenient to use in actual use. Each time the film was broken, the user was required to hold the handle fixing rod to operate the film breaking cylinder and the film breaking teeth. After long-term use, the user's hands became tired, affecting the film breaking effect and easily causing damage to the film and planted seedlings. Utility Model Content
