Description

A simple film cutter

technical field

The invention relates to the technical field of agricultural machinery, in particular to a simple film cutter.

Background technique

In our country, the use of plastic film is very extensive, such as the covering technology applied to vegetables and melons, and the use of it to keep fresh, etc., because it has brought certain economic benefits to people, so the use of plastic film has become a popular choice for people in agricultural production. It is an indispensable tool in the environment. As the service life increases, people blindly pursue economic benefits but ignore the recycling of the plastic film. If the plastic film is not recycled and remains in the soil, it will lead to damage to the quality and structure of the soil. , will have a certain impact on the production of the next year, so the recycling of plastic film is necessary, because in the recycling of plastic film in Southwest China, people first have to cut the film from the middle with scissors, and then collect the film, but It takes time to cut the film, which will greatly reduce the efficiency of film collection.

Contents of the invention

The technical problem to be solved by the present invention is to provide a simple film cutting device, which facilitates rapid film cutting during the film harvesting process, improves the film recovery efficiency, and overcomes the deficiencies of the prior art.

The present invention is achieved like this:

A simple film cutter, comprising a horizontally placed guide tube, a vertically placed blade is arranged outside the tail of the guide tube, a square steel tube is placed above the inner side of the guide tube, a connecting rod is arranged between the guide tube and the square steel tube, and the connecting rod is connected to the horizontal plane form an angle.

In the aforesaid simple membrane cutter, an arc-shaped guide head is set at the front end of the guide pipe. By setting the guide head, the weeds or soil slopes in front are smoothed in actual work to facilitate the movement of the diaphragm device.

In the aforesaid simple film cutter, the connecting rods are at least two and parallel to each other, the front end of the connecting rod is fixed with the guide tube by a nut, and a short sleeve and a long sleeve are arranged at the tail of the connecting rod, and the short sleeve The barrel is inserted into the long sleeve, a chute is set on the short sleeve located in the long sleeve, and a threaded hole is set on the long sleeve corresponding to the chute, and the screw is inserted into the threaded hole and corresponds to the chute to realize the short sleeve. The barrel moves within the long sleeve, and a pre-tension spring is set in the tail of the long sleeve. The steel pipe is fixed with the bolts. By setting the connecting rod and the long and short sleeves, the operator can push the guide tube to move when standing upright. At the same time, by setting the pre-tightening spring, the connecting rod is always pressed against the guide tube within a certain pressure range. , so that the blade is close to the film under the plant stem, which is convenient for cutting the film.

In the aforesaid simple and easy film cutter, a handle is provided at the tail of the square steel pipe.

Due to the adoption of the above-mentioned technical scheme, compared with the prior art, the present invention adopts the method of pushing the blade to cut and recycle, which is much better than the manual cutting method in the prior art, and the present invention has simple structure, convenient manufacture and strong practicability .

Detailed ways

Embodiment of the present invention: a simple and easy film cutting device, as shown in the accompanying drawings, includes a horizontally placed guide tube 1, characterized in that a vertically placed blade 6 is set outside the tail of the guide tube 1, and the square steel pipe 5 is placed on Above the inner side of the guide pipe 1, a connecting rod 12 is arranged on the guide pipe 1 and the square steel pipe 5, and the connecting rod 12 forms an included angle a with the horizontal plane.

Wherein a section of arc-shaped guide head 13 is set at the front end of guide pipe 1, and there are at least two connecting rods 12 parallel to each other. The short sleeve 3 and the long sleeve 4 are set, the short sleeve 3 is inserted into the long sleeve 4, a chute 10 is arranged on the short sleeve 3 inside the long sleeve 4, and the long sleeve at the corresponding position of the chute 10 4 is provided with threaded hole 7, and the screw is inserted in the threaded hole 7 and corresponds to the chute 10 to realize the limit movement of the short sleeve 3 in the long sleeve 4, and a pre-tension spring 11 is set in the tail of the long sleeve. The front end of tight spring 11 tops short sleeve 3, and spring head 8 is set at the afterbody of pretension spring 11, and this spring head 8 penetrates square steel pipe 5 and is fixed with bolt, and handle 9 is set at square steel pipe 5 afterbody.

The working principle of the present invention on the mulch recovery machine at the seedling stage is as follows: firstly, the simple rod puller is pushed forward by holding the handle tightly, and the short sleeve is embedded in the long sleeve, and the short sleeve is positioned in the long sleeve through a nut and two A spring is placed in the sleeve. In order to press the diaphragm inward from the root of the plant, it can be realized, and a chute is opened on the short sleeve, so that it is convenient for the spring to move between the sleeves. Telescopic, when working, you only need to hold the handle and push the film cutter forward to realize the film cutting. If the guide pipe is not close to the root of the plant, just press the square steel pipe inward, because there is a spring head between the two sleeves , so the plant will not be pushed to the ground due to excessive force. , easy to collect film, saving time and effort.
