Puncture tearing spike tooth type film and belt breaking mechanism and method

Abstract

The invention relates to a puncturing and tearing spike tooth type film and belt breaking mechanism and method. The puncturing and tearing spike tooth type film and belt breaking mechanism is structurally and mainly composed of a telescopic rod, a pressing plate, a rotating rod and puncturing and tearing spike teeth. The device is characterized in that the first telescopic rod is hinged to the film mulching seeder, the second telescopic rod is connected with the pressing plate, and the puncturing and tearing spike teeth are connected with the rotary rod. The first telescopic rod extends to drive the puncturing and tearing spike tooth type film and belt breaking mechanism to move downwards; a second telescopic rod extends to drive a pressing plate to press the film and the drip irrigation tape, the second telescopic rod continues to extend to drive puncture tearing nail teeth through a rotary rod to prick the film and the drip irrigation tape into soil, the second telescopic rod continues to extend to drive puncture tearing nails to rotate through the rotary rod to tear the film and the drip irrigation tape, and the film and the drip irrigation tape are broken; after the film and the drip irrigation tape are broken, the telescopic rod I retracts and pulls up the spike-tooth type film and tape breaking mechanism to puncture and tear, and the machine continuously advances. The mechanism is simple in structure and low in cost.

Description

Technical Field

[0001] This invention relates to a puncture-tearing nail-tooth type film-severing and strip-severing mechanism and method, belonging to the field of film-mulching and seeding equipment. Background Technology

[0002] Film mulching and soil covering sowing technology is widely used in agricultural planting. In film mulching and soil covering sowing operations, tractors need to change rows when they reach the edge of the field, and the film and tape need to be cut before changing rows. At present, most film mulching and soil covering sowing machines use an additional hydraulic mechanism to drive the film cutting mechanism to achieve film and tape cutting. The machines are complex and costly, and the drip irrigation tape is difficult to break, making it difficult to promote and use on a large scale. Summary of the Invention

[0003] This invention relates to a puncture-tear nail-tooth type film-breaking and strip-breaking mechanism and method, which aims to realize the film-breaking and strip-breaking function when changing rows during film laying, soil covering and sowing operations, while simplifying the machine structure and reducing costs.

[0004] This invention relates to a puncture-tear nail-type film and tape breaking mechanism and method, the structure of which mainly consists of a telescopic rod, a pressure plate, a rotating rod, and puncture-tear nail teeth; characterized in that the first telescopic rod is hinged to the film-laying seeder, the second telescopic rod is connected to the pressure plate, and the puncture-tear nail teeth are connected to the rotating rod; the extension of the first telescopic rod causes the puncture-tear nail-type film and tape breaking mechanism to move downward; the extension process of the second telescopic rod is divided into three stages: in the first stage, the extension of the second telescopic rod causes the pressure plate to press the film and drip irrigation tape; in the second stage, the second telescopic rod continues to extend, driving the puncture-tear nail teeth through the rotating rod to embed the film and drip irrigation tape into the soil; in the third stage, the second telescopic rod continues to extend, driving the puncture-tear nail teeth through the rotating rod to generate a rotational motion to tear the film and drip irrigation tape, causing the film and drip irrigation tape to break; after the film and drip irrigation tape break, the first telescopic rod retracts to pull up the puncture-tear nail-type film and tape breaking mechanism, and the machine continues to move forward; this mechanism has a simple structure and low cost.

[0005] Compared with existing technologies, this invention utilizes the extension movement of the telescopic rod to drive the piercing and tearing nail teeth through the rotating rod to generate rotational motion that tears the film and drip irrigation tape, causing the film and drip irrigation tape to break. The structure is simple, the cost is reduced, and it is conducive to the further application and promotion of film laying, soil covering and sowing equipment. Attached Figure Description

[0010] The following is in conjunction with the appendix Figure 1-3 The structural principles and implementation schemes of the present invention will be described in detail.

[0011] This invention relates to a puncture-tear nail-type film-breaking and strip-breaking mechanism and method. Its structure mainly consists of a telescopic rod, a 1-pressing plate, a 5-rotating rod, and a 6-puncture-tear nail; characterized in that the 3-telescopic rod one is hinged to the 4-film-laying and seeding machine, the 2-telescopic rod two is connected to the 1-pressing plate, and the 6-puncture-tear nail is connected to the 5-rotating rod.

[0012] The working process of this invention is as follows: During operation, the 3-telescopic rod one extends, driving the 6-puncture and tearing nail tooth-type membrane and tape breaking mechanism to move downward; the 2-telescopic rod two extends, driving the 1-pressing plate to press the membrane and drip irrigation tape together; the 2-telescopic rod two continues to extend, driving the 6-puncture and tearing nail teeth through the 5-rotating rod to embed the membrane and drip irrigation tape into the soil; the 2-telescopic rod two continues to extend, driving the 6-puncture and tearing nails through the 5-rotating rod to generate a rotational motion to tear the membrane and drip irrigation tape, causing the membrane and drip irrigation tape to break; after the membrane and drip irrigation tape break, the 3-telescopic rod one retracts and pulls up the 6-puncture and tearing nail tooth-type membrane and tape breaking mechanism, and the machine continues to move forward.

Telescopic rod one is hinged to the film-laying seeder, telescopic rod two is connected to the pressure plate, and the piercing and tearing spikes are connected to the rotating rod. The extension of telescopic rod one causes the piercing and tearing spike-type film and drip tape breaking mechanism to move downwards.
