Description

Technical Field

[0001] The utility model relates to the field of residual film recovery tools, in particular to a residual film compression mechanism of a residual film recovery machine. Background Art

[0002] Ground film is widely used in agricultural planting for covering crop planting. Ground film is mainly used to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, thereby promoting plant growth. However, after the crops are harvested, in order to prevent these residual films from polluting the soil and the environment, they need to be recycled at this time. At the same time, the recycled residual films need to be compressed to remove most of the air in the film and reduce the volume, so that they can be stored and transported more conveniently and compactly.

[0003] After searching the patent document with the announcement number CN111684875A, it was found that the device in the patent document rotates counterclockwise under the action of chain drive, and the packing roller is provided with tooth-shaped protrusions. The recovered residual film is rotated and compressed under the action of the tooth-shaped protrusions, and the residual film is packed into shape.

[0004] The device in the patent document cannot effectively remove the air bubbles between the residual films, thus failing to effectively reduce the volume of the residual film roll. Meanwhile, the residual film becomes fragile after aging. The device in the patent document only relies on the friction generated by the relative rotation between the packing roller and the residual film for compression, and the compression rate is low.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 6 As shown, a residual film compression mechanism of a residual film recycling machine includes a recycling component 2 and a residual film roll 3, characterized in that: a compression component 1 for compressing the residual film roll 3 is provided between the recycling component 2;

[0027] In this embodiment, the compression assembly 1 includes a compression cylinder 101, a push plate 102 is fixedly connected to the extended end of the compression cylinder 101, a plurality of bubble cones 104 are arranged on the side of the push plate 102 away from the compression cylinder 101, sliding bosses 105 are symmetrically arranged on both sides of the push plate 102, and two sliding bosses 105 are respectively provided with a C-shaped frame 106 at one end away from the push plate 102, and the upper ends of the two C-shaped frames 106 are fixedly connected to the mounting plate 108, and the two C-shaped frames 106 are provided with rollers for rolling on the sliding bosses 105. 107, there are two groups of recovery components 2, and they are symmetrically arranged on both sides of the push plate 102. The sliding boss 105 is away from the compression cylinder 101. A groove structure for limiting the movement trajectory of the roller 107 is opened. When the residual film roll 3 begins to be compressed, the compression cylinder 101 pushes the push plate 102 to move toward the extrusion plate 103, and the bubble cone 104 on the push plate 102 pierces the residual film roll 3 to release the air in the residual film roll 3. At the same time, when the push plate 102 moves a certain distance, the front end of the bubble cone 104 passes through the hole of the extrusion plate 103.

[0028] In this embodiment: the recovery component 2 includes a motor 201, which is fixedly connected to the side of the mounting plate 108 away from the compression cylinder 101, a recovery fork 202 is fixedly provided at the output end of the motor 201, and the residual film roll 3 is wound between the two recovery forks 202, a scraper 203 is provided on the side of the mounting plate 108 away from the motor 201, and the recovery fork 202 passes through a hole in the scraper 203, and the upper and lower ends of the scraper 203 are fixedly connected to a shell 206 for protecting the entire device, a guide component is provided at the lower end of the mounting plate 108, and the scraper 203 is fixedly connected to the end away from the bubble cone 104 with an extrusion plate 103, and the extrusion plate 103 is provided with a hole for the bubble cone 104 to pass through, and the bottom of the shell 206 is provided with an outlet near the extrusion plate 103 The material bin plate 207 and the discharge bin plate 207 are rotatably connected to the shell 206 on the side away from the extrusion plate 103, and lock buckles 208 are provided on both sides of the discharge bin plate 207. When the residual film is recovered, the symmetrically arranged motors 201 rotate in the same direction and at the same speed, and the residual film entering the device is wound between the recovery forks 202, and finally a residual film roll 3 is formed. While compressing the residual film roll 3, the push plate 102 drives the sliding boss 105 to move, and the groove structure of the sliding boss 105 causes the roller 107 to slide along the groove, thereby pushing the recovery component 2 gradually away from the scraper 203, and the residual film roll 3 between the recovery forks 202 is scraped off by the scraper 203, which is convenient for compression. The lock buckle 208 is opened to open the discharge bin plate 207, and the compressed residual film roll 3 can be unloaded.

[0029] In this embodiment: the guide assembly includes a slider 204, one side of the slider 204 is fixedly connected to the lower end of the mounting plate 108, and the guide block of the slider 204 faces downward, and a slide groove 205 for the linear sliding of the guide block is provided under the slider 204, one end of the slide groove 205 is vertically fixedly connected to the shell 206, and the other end of the slide groove 205 is vertically fixedly connected to the scraper 203. In the process of the recovery assembly 2 moving away from the scraper 203, the slider 204 fixedly installed on the mounting plate 108 drives the recovery assembly 2 to move linearly along the slide groove 205 in a direction perpendicular to the scraper 203, which is conducive to the residual film roll 3 being completely scraped off by the scraper 203.

[0030] Working principle: When the residual film is recycled, the symmetrically arranged motors 201 rotate in the same direction and at the same speed, and the residual film entering the device is wound between the recycling forks 202, and finally a residual film roll 3 is formed. When the residual film roll 3 is compressed, the compression cylinder 101 pushes the push plate 102 to move toward the extrusion plate 103, and the bubble cone 104 on the push plate 102 pierces the residual film roll 3 to release the air in the residual film roll 3. When the push plate 102 moves a certain distance, the front end of the bubble cone 104 passes through the hole of the extrusion plate 103, and at the same time, the push plate 102 drives the sliding boss 105 to move, and the sliding boss 10 5 makes the roller 107 slide along the groove, thereby driving the recovery component 2 to gradually move away from the scraper 203, and the residual film roll 3 between the recovery forks 202 is scraped off by the scraper 203, which is convenient for compression. In the process of the recovery component 2 moving away from the scraper 203, the slider 204 fixedly installed on the mounting plate 108 drives the recovery component 2 to move linearly along the slide groove 205 in a direction perpendicular to the scraper 203, which is conducive to the residual film roll 3 being completely scraped off by the scraper 203. After the residual film roll 3 is compressed, the lock buckle 208 is opened to open the discharge bin plate 207, and the compressed residual film roll 3 can be unloaded;

[0031] After completing the compression work on the residual film roll 3, the push rod of the compression cylinder 101 contracts, driving the push plate 102 and the sliding boss 105 to gradually retreat, and the roller 107 slides along the groove, driving the recovery component 2 to return to the original working position along the slide groove 205.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
