Description

Partition type residual film recycling machine

technical field

The utility model relates to the field of agricultural machinery, in particular to a partition type residual film recycling machine.

Background technique

Plastic film mulching technology is widely used in agricultural production in my country, and the application of plastic film has greatly improved the yield of crops. The mulch currently used in my country is mainly 0.006-0.008mm polyethylene mulch. This kind of mulch is very thin and has low strength, which has caused great difficulties for mechanized recycling, and polyethylene can only be degraded in the soil after 200-400 years. The plastic film covered in the field, under the strong action of wind, sand and sunlight, the strength of the plastic film is greatly reduced. my country's current residual film recycling machinery is mainly divided into three categories according to the different film harvesting time: residual film recycling machinery at seedling stage, residual film recycling machinery after autumn harvest, and residual film recycling machinery before spring sowing. The recovery efficiency of residual film is not high, and it cannot be popularized and used in a large area. For removing the film at the seedling stage, the dripping period of cotton is shortened by 3-4 days due to the drought caused by excessive water evaporation. For Xinjiang's irrigation method based on drip irrigation, removing the film at the seedling stage is increasingly unacceptable by farmers. For the film picking machine before spring sowing, due to the short time of spring sowing and spring plowing, it is necessary to grab the moisture and sow after the land is leveled. At this time, the time and machine power are tight to pick up the film before sowing, and it is difficult to recycle the film due to the long-term weathering of the film in the soil. At present, the residual film recycling machine after autumn harvest is widely used, and the residual film recycling machine after autumn harvest is divided into two types: one is the film and stalk mixed harvesting type, and the other is the film and stalk separation type. However, no matter which method is used, the cotton stalks must be treated first, which increases the damage of the residual film, reduces the recovery rate of the residual film, and even lower the recovery rate of the edge film buried in the soil.

Contents of the invention

The purpose of this utility model is to provide a partition type residual film recovery machine, which can recover the residual film in partitions, and does not need to deal with the cotton stalks when collecting the film, so as to reduce the mechanical damage to the waste film and ensure the integrity of the waste film , and then improve the recovery rate of waste film and the working efficiency of machinery.

The purpose of this utility model is achieved in this way. A partition type residual film recovery machine includes a frame. At the tail of the frame, three groups of film rolls arranged at intervals in the left, middle and right are respectively installed through the lifting limit rod. On the radially outer surface of the film rolling rollers, film lifting nails are arranged in staggered intervals. A film cutting device is respectively installed on the inner sides of the left and right two groups of film rolling rollers and the front frames on both sides of the middle film rolling roller. The film device includes a vertically arranged adjustment rod, the lower end of the adjustment rod is installed with a film cutting tooth plate through a bearing, and a film lifting device is installed under the rear frame of the film cutting tooth plate on the left and right sides respectively through the adjustment rod. The lower end of the adjusting rod of the device is respectively tilted and hinged to a film lifting shovel through a limit nut.

The frame of the utility model is connected with the tractor by 3-point suspension. During operation, the film cutting device first cuts the film at a distance of about 20mm from the cotton stalk, divides the entire film into the middle film and the left and right films, and then rolls the film by the middle film roller. The residual film in the middle is recovered, and the edge films on both sides are covered by soil. First, the residual film is shoveled to the surface by the film lifting device, and then the edge film is recovered by the left and right sets of film rolling rollers of the edge film collecting device. Arrive at the field, lift the machine under the action of the hydraulic device of the tractor, manually remove the residual film wound on the film harvesting device, and complete a film harvesting operation so far.

The utility model adopts the method of subdivision to cut and process the residual film, which ensures the integrity of the waste film and improves the recovery rate of the residual film. During the recycling process of the edge film, the machine adds a film lifting device to shovel the edge film on the ground surface, reducing the difficulty of collecting the edge film. The partition type residual film recycling device is simple and convenient to use, has good working stability, low manufacturing cost and high working efficiency. Both the film cutting mechanism and the film shoveling mechanism of the device can be adjusted according to different terrains and different soil properties, which improves the flexibility of use.
