Description
Technical Field
The invention relates to the technical field of agricultural machinery, in particular to a membrane-soil separation device for recovering residual membranes of farmlands.
Background
The plastic film mulching cultivation technology is an advanced cultivation technology which improves and optimizes cultivation conditions, overcomes adverse condition influence, achieves early maturing, high yield and high efficiency, and is widely applied at home and abroad. Most of the mulching films at the present stage adopt polyvinyl hydrocarbon compound films, the mulching films are difficult to degrade under natural conditions, if the mulching films are not recovered in time, serious 'white pollution' in the field can be caused after long-term accumulation, adverse effects can be caused on the ecological environment, the soil structure and the growth and development of crops, and the timely recovery of residual films is an important link. In order to solve the growing residual film pollution, researchers at home and abroad do a lot of work on the aspect of residual film recovery, wherein mechanical residue picking is the optimal method.
Foreign research on mulching film recycling machines was early (beginning in the early 20 th century), while national research on mulching film recycling machines was relatively late (beginning in the 80 th 20 th century). As the mulching films used abroad are relatively thick (generally larger than 0.2mm), the mulching films have higher strength during recycling, the principle of a mulching film recycling machine is mainly to separate the mulching films from soil by utilizing the self tensile force of the mulching films, as early as 1993, Sawyer and Rober in the United states develop a mulching film recycling machine, the working principle of the machine is to roll the mulching films from the ground by utilizing a roll roller, and the machine comprises a device with the speed of a film rolling roller matched with the working speed of a recycling machine. France also has corresponding achievements in the research, the working principle is to use a film removing shovel to loosen and scrape the soil pressed on the two sides of the mulching film, and then manually lift and wind the removed residual film on a winding drum.
The mulching film used in China is relatively thin (generally 0.006-0.008 mm), the tensile strength of the mulching film during recovery is very low, the film surface is very easy to crack, and foreign mulching film recovery machinery is basically not suitable for being used in China. Therefore, when the domestic residual membrane is recycled by kneading, the research focuses on key components such as membrane starting, membrane collecting, membrane removing, membrane collecting and the like, and the research also comprises the research on a membrane soil separation mechanism and a membrane impurity separation mechanism. For example, a plough layer residual film harvester of 1QZ-3900 type developed by Mashall et al is a representative type, a soil residual film mixture separation device is designed to clean plough layer residual film stubble, but the working effect of a grid type tail screen serving as a film soil separation device when facing sand soil in the south needs to be verified. The IFMJ-850 type waste film picking machine is a representative of an eccentric drum type machine, and mainly solves the problem that the residual film is easily brought into a drum due to overlarge gap of a traditional picking drum through optimization research of Anlun and Fang and the like. The spike type plastic film residue recycling machine designed by the mustache et al uses the cam principle to complete the film picking and releasing process, but the drum type plastic film residue recycling machine is basically not provided with an independent film soil separating mechanism, so that the plastic film residue is clamped and mixed, and the recycling of the plastic film residue is hindered. The present bullet tooth-like incomplete membrane picks up machine utilizes the cam slide to pick up the membrane bullet tooth and accomplish flexible, picks up the operation through playing the tooth to incomplete membrane, has effectually reduced the incomplete membrane condition of tearing of picking up the in-process, nevertheless has bullet tooth vibration too big and card dead phenomenon in the motion process, leads to the operation process of demoulding not smooth and easy. The toothed chain type residual film recycling machine is large in popularization range at present, the picking effect and the film conveying smoothness are important points of research on a toothed chain type residual film recycling mode, and the research on the film stripping performance is accelerated. Roller wound form plastic film residue collector simple structure, working property is stable, but the model lacks the edulcoration and removes native mechanism, and the deciduate also has the limitation, leads to the value reduction of the plastic film residue recycle once more after picking up.
To sum up, the problem that farmland plastic residue collector that has membrane soil separation function exists mainly includes following three aspects: firstly, separating residual membranes and soil recovered by a membrane selecting mechanism; conveying the separated residual film to a film collecting box; thirdly, returning the separated soil to the field.
