Description
Technical Field
The invention relates to the technical field of agricultural machinery, in particular to a mulching film recycling machine with an automatic stripping function.
Background
In China, mulch films become one of important material data in agricultural production, and development of mulch film covering technology drives leap of agricultural productivity. Although the mulching film has the functions of warming, preserving soil moisture, preventing diseases, resisting insects and the like for crops, a large amount of mulching films are used, so that a large amount of residual films are left in the fields after autumn and are difficult to decompose, and the huge challenges brought to the subsequent agricultural production are brought, and a farmland ridge surface post-autumn residual film recycling machine is needed to solve the residual film problem. After the mulching film is subjected to sun-drying and rain-drying, the physical characteristics of the mulching film are greatly changed, and all the problems are brought to the picking up of the residual film and the stripping after the picking up.
At present, domestic residual film recycling machines are divided into two main types: the mechanical type and the air suction type are mainly mechanical type and widely popularized mechanical type types at the present stage because the air suction type is too much mixed to be accepted by people, and the mechanical type is as follows: the telescopic rod tooth type, spring tooth type, shovel stubble type, gear type, tooth chain type and the like, and each machine has respective working characteristics.
At present, the existing automatic residual film stripping device has the following steps:
1. automatic film stripping device of spike type residual film recycling machine. The machine consists of a cam mechanism, spike teeth, a brush demoulding device, a recovery box and a frame, and has good picking effect on broken small residual films in the field. When the machine works, the spike teeth rotate along with the roller to prick the residual film on the soil surface and in the plough layer, the push rod pushes the film stripping plate to strip the film, the film picking and stripping processes are completed, the film stripping device is designed in the machine to assist in stripping, and when the residual film is pricked by the picking spike teeth and sent to the inlet of the recovery box, the stripping roller which rotates forward brushes from the spike teeth and the roller to fall into the residual film recovery box.
2. Automatic stripping device of tillage crushed residual film recycling machine. The tillage broken plastic film residue recovery device and the tillage machine are combined to form a tillage broken plastic film residue recovery operation machine, pick-up teeth are uniformly distributed on the rollers, stripping teeth and finger-shaped pick-up teeth are mutually matched in a staggered manner, and plastic films are removed from the pick-up teeth in the process of mutual rolling of the two rollers and fall into the film collecting box.
3. Automatic film stripping device of chain tooth harrow type residual film recycling machine. When the film stripping device works, the upper side blades of the film stripping device are consistent with the conveying direction of the residual film, the driving chain of the film stripping device rotates anticlockwise under the action of the power system, the moving speed of the film stripping blade is higher than the conveying speed of the residual film under the drive of the chain wheel, the film stripping blade can tear and scrape the residual film at the same point for a plurality of times due to the fact that the film stripping speed is higher than the conveying speed of the residual film, the moving speed of the torn residual film is gradually synchronous with the film stripping blade, when the residual film moves to the top end of the film stripping sprocket rake, the residual film overcomes the adsorption and hanging effect of the sprocket rake under the action of centrifugal force, and is separated from the sprocket rake and falls into the residual film recovery box to finish film stripping.
The above-mentioned automatic stripping methods have various advantages, but there are many areas where improvement is needed:
1. although the automatic demolding device of the spike-type residual film recycling machine is ingenious in structure, the matching requirement of parts which are required to be ensured during processing is high, the structure is too complex, the processing cost is high, and the design precision is difficult to ensure.
2. The automatic film removing device of the tillage broken film recycling machine has the advantages of simple structure and low manufacturing cost. However, the method is poor in adaptability to physical characteristics of the residual film after autumn, and serious in tearing of the residual film after autumn, is not beneficial to secondary recovery of the residual film, is not beneficial to smooth collection of the residual film into the film collecting box, and is also serious in mechanism abrasion.
3. The automatic film stripping device of the chain tooth harrow type film residue recycling machine has compact structure and high working reliability, but the whole machine occupies large space, and in addition, the problem of tearing the post-autumn film residue exists.
