[0002] In the forage processing industry, baling and laminating are important links to ensure the quality of forage and facilitate storage and transportation. Traditional forage baling methods mostly rely on manual operation, which is inefficient and has unsatisfactory laminating effects. With the continuous advancement of technology, automated forage balers have emerged, but their laminating mechanisms are often complex in structure, cumbersome in operation, and the laminating quality is unstable. Therefore, it is particularly important to develop a forage baler laminating mechanism with a simple structure, convenient operation, and good laminating effect. The forage baler laminating mechanism involved in this technology optimizes the design of the film rolling component and the tightening component to achieve automated operation of forage baling and laminating, improve production efficiency, and at the same time ensure the quality and stability of the laminating, providing an efficient and reliable solution for the forage processing industry.

[0003] Chinese patent number CN214729906U discloses a rapid film coating device for a forage baler, which stably clamps the forage roll by adjusting the clamping roller, fixes the front and rear positions of the forage roll by the limit rod, and finally drives the film to rotate by the rotation of the rotating rod, and realizes the rotation of the forage roll under the rotation of the clamping roller, thereby realizing the packaging of the forage roll, solving the problem that the forage pile is easy to become loose during the packaging process of the baler in the prior art;

[0004] The above-mentioned equipment also has the following problems during use: during use, when the grass roll is covered with film, because the tightness of each grass roll is different during the covering process, the grass roll is easily broken due to the force exerted by the rotating rod on the grass roll during the covering process, causing difficulty in covering the film;

[0005] Therefore, it is necessary to provide a new film covering mechanism of a forage baler to solve the above technical problems. Utility Model Content

[0011] Compared with the related art, the film covering mechanism of the forage baler provided by the utility model has the following beneficial effects:

[0012] The utility model provides a film covering mechanism of a forage baler. Through the action of a tightening component, the forage bale is tightly tightened during the forming process, ensuring that the shape of the forage bale is regular and the density is uniform. Subsequently, the film is evenly unfolded and covered on the outer surface of the forage bale under the action of a pulling rope, achieving a tight and uniform film covering effect. This film covering method can not only effectively protect the forage from the influence of the external environment, such as rain, dust, etc., but also prevent the forage from being scattered and lost during storage and transportation, thereby ensuring the quality and value of the forage.

[0024] The working principle of the film covering mechanism of a forage baler provided by the utility model is as follows:

[0025] First, the motor inside the motor box 10 is started, and the motor drives the crushing roller 12, the forming roller 17 and the supporting roller 13 to start working. The grass enters from the grass inlet of the film covering box 3, is guided by the shovel mouth 9, and enters the area of ​​the crushing roller 12. The crushing roller 12 crushes the grass to make it reach a particle size suitable for packaging. Then, the crushed grass is further processed by the supporting roller 13 and the forming roller 17 to help the grass form a tight and regular cylindrical or rectangular grass bag in the film covering box 3. At the same time as the grass bag is formed , the tightening assembly inside the film-covering box 3 starts to work, the telescopic rod 21 in the tightening assembly pulls the movable block 20 backward to move, thereby driving the connecting rope 15 and the tightening plate 11 to move toward the direction of the hay bag, the tightening plate 11 slides in the slide groove 14, and clings to the outer surface of the hay bag to tighten the hay bag. At the same time, the elastic rope 18 provides a certain elastic force to help the tightening plate 11 better fit the hay bag. After the hay bag is tightened to a certain extent, the tightening plate 11 gradually cancels the tightening effect on the hay bag;

[0026] The winder 2 starts working, and drives the film rolling assembly on one side of the coating box 3 to rotate through the pulling rope 4. The bracket 7 on the bottom of the coating box 3 contacts and forms a support with one side surface of the shell 1, so that the coating box 3 rotates from a vertical state to be parallel to one side of the shell 1. The hydraulic push rod 23 in the film rolling assembly pushes the assembly roller 24 and the film roll thereon into the interior of the shell 1 from the opening 16, close to the hay bale, so that the starting end of the film roll can fit on the outer surface of the hay bale. As the hay bale continues to form and move forward, the film is gradually unfolded and covers the outer surface of the hay bale under the action of the rolling of the hay bale, completing the coating of the hay bale.
