Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to a machine for recycling residual agricultural film. Background Art

[0002] With the rapid advancement of my country's industrialization and urbanization, coupled with the general trend of continuous transfer of rural land, a large number of rural laborers have moved to cities, resulting in a decline in agricultural production efficiency, severe shortages and shortages of labor in agricultural production, and lack of advanced technology and equipment in agricultural production. The existing production and management methods in rural areas can no longer meet the needs of modern agricultural development. Therefore, accelerating the level of agricultural mechanization and improving labor productivity are urgent issues to be solved in order to achieve agricultural modernization and promote the comprehensive and coordinated development of agriculture and rural economy. It is also an objective requirement to improve the level of agricultural material and technical equipment in my country and develop modern agriculture.

[0003] As an important agricultural material, agricultural mulch film has played an important role in increasing agricultural production and farmers' income. However, in recent years, with the continuous increase in the amount of agricultural film used and the number of years of use, the residual film in the tillage layer of farmland soil has accumulated more and more, and the problem of "white (black) pollution" in some areas has become increasingly prominent. Waste agricultural film remains in the cultivated soil, causing serious harm to the growth of crops, the soil ecological environment, and the appearance of villages. Therefore, strengthening the recycling, treatment and reuse of waste agricultural film and preventing and controlling the "white (black) pollution" of residual film in farmland is of great significance for protecting the cultivated soil environment and promoting the green development of agriculture.

[0004] At present, most agricultural production activities are carried out with the help of mechanized equipment. However, in many areas, after the harvest of crops, the treatment of residual film in farmland still mostly relies on manual recovery. Even in the farmland film recovery machinery, it is completed by single-function recovery equipment. In addition, many agricultural films are prone to aging and rotting under the sun for a long time, resulting in poor recovery effect of residual film in farmland, reduced treatment and reuse rate of residual film, and very low agricultural production efficiency. Especially in some areas where mechanized operations cannot be implemented (such as mountainous areas, hilly forest areas, Loess Plateau, fixed small-scale agricultural scientific research experimental areas, etc.), crop residual film can only be recovered manually, and mechanized operations are significantly inhibited.

[0033] The shaft II 6 is rotatably connected to the side support plate 423 .

[0034] The left film roller 12 and the right film roller 13 rotate in opposite directions.

[0035] The elastic steel bars Ⅰ16 and Ⅱ17 are bent in order to reduce the winding of the film and to gather the film from both sides to the middle to facilitate the collection of residual film.

[0036] The sprocket IV 18 and the right film roller 13 are installed on the shaft VII 43 ; the sprocket V 19 and the left film roller 12 are installed on the shaft VIII 44 .

[0037] The sprocket VI 22 is placed on the outside of the vertical beam I 426 .

[0038] The film collecting box 38 is cylindrical, and a number of through holes 41 are evenly distributed on its wall. A rotating disk 39 with a rotating shaft is provided in the center along the length direction, and an inlet connected to the inclined surface 37 is provided on the horizontal side. The two ends of the rotating shaft pass through the two ends of the film collecting box 38 and are fixed by bearing VI, and one end is provided with a sprocket X32; the sprocket X32 is connected to the sprocket IX30 through the chain V31.

[0040] The diameter of the laminating roller II 36 is greater than the diameter of the laminating roller I 35 .

[0041] Working principle: The universal coupling 1 is connected to the tractor output shaft to obtain power. The universal coupling 1 rotates to drive the spur gear I3 and the spur gear II11 to rotate, so that the shaft I2 and the shaft III10 rotate in opposite directions. The sprocket II8 installed on the shaft I2 transmits power to the sprocket V19 through the chain II15. The sprocket V19 is coaxially connected with the left film roller 12, so that the left film roller 12 rotates.

[0042] Similarly, sprocket III9 installed on shaft I2 transmits power to sprocket IV18 through chain I14. Sprocket IV18 is coaxially connected to the right film-starting roller 13. Elastic steel bars I16 and II17 are respectively installed on the left film-starting roller 12 and the right film-starting roller 13. The film-starting rollers on the left and right sides rotate in opposite directions, so that the elastic steel bars I16 and II17 remove the covering soil buried on the film.

The sprocket VIII29 is installed on the shaft VI28 and drives the shaft VI28 to rotate. The rolling roller II36 is installed on the shaft VI28.

The film collecting shovel 33 separates the film wound by the nail teeth 34, and the film passing through the film collecting shovel 33 enters the rolling roller II 36 and the rolling roller I 35. The rolled residual film follows the inclined surface 37 and enters the film collecting box 38. The film collecting box 38 is designed with a rotating disk 39. The rotating disk 39 can turn the residual film over and gradually bundle it. The turning of the residual film causes the sand to flow out of the film collecting box 38 through the through hole 41 on the film collecting box.
