Description

Greenhouse volume film moment of torsion transmits telescopic mechanism

Technical field

The utility model belongs to the industrialized agriculture technical field, is specifically related to a kind of greenhouse volume film moment of torsion and transmits telescopic mechanism.

Background technology

Industrialized agriculture is to rely on scientific and technological advances and the new high-tech industry that forms, is the typical subdiscipline of tool in the agricultural engineering subject.It is the important foundation that traditional farming moves towards modern agriculture, is that agricultural realizes large-scale commercial, modern concentrated reflection, is that agricultural realizes high yield, high-quality, effective measures efficiently, also provides the important technique measure of fresh produce.In 21 century, industrialized agriculture will become the new industry of most active agricultural.

Along with the development of agricultural modernization propelling, industrialized agriculture, plastic tunnel, daylight type plastic greenhouse and Lian Dong plastic greenhouse become modern agriculture and produce critical facility, and China's plastic tunnel, daylight plastic greenhouse and Lian Dong plastic greenhouse amounted to 2,000,000 hectares in 2004.Compared with developed countries, the modern installations of China agricultural level also has big gap, and the existing greenhouse of China is still based on simple and easy daylight plastic greenhouse and little shed.

At present, the volume film of simple and easy daylight plastic greenhouse of China and little shed is generally based on manually, and operating efficiency is low.For some length bigger simple and easy daylight plastic greenhouse and little shed, because load is heavier, manual operation is difficult to finish.Thereby the demand of electronic film rolling device is increasing.

Fig. 1 is the little shed film rolling device in existing greenhouse.Motor 5 links to each other with film rolling arm 3 by universal ball joint at the A point, and film rolling arm 3 links to each other with film rolling rob 4 by universal ball joint at the B point again, covers greenhouse heat-insulating film 1 on the little shed and fixes on the film rolling rob 4 by volume film clamping.The rotation of motor shaft passes to film rolling arm by universal ball joint, and the rotation of film rolling arm passes to film rolling rob by universal ball joint again, thereby makes film rolling rob rotate on little shed bow member and move along its profile, finishes volume film function.General and the off-gauge circle of little its shape of shed bow member, and because installation accuracy is not high, its tangent plane generally has certain scrambling, thereby the transmission of high pulling torque when seeking a kind of film rolling arm and both can realize rolling up film, can realize that again the flexible device of film rolling arm is those skilled in the art's a goal in research.

Summary of the invention

The purpose of this utility model is to propose a kind of greenhouse volume film moment of torsion and transmits telescopic mechanism.

The greenhouse volume film moment of torsion that the utility model proposes transmits telescopic mechanism, is made up of insulation film made 1, bow member 2, film rolling rob 4, motor 5, film rolling arm sleeve 6, film rolling arm expansion link 7, bearing 8, bearing connecting axle 9, and its structure as shown in Figure 1.Wherein, insulation film made 1 is covered on the bow member 2, and the one side schedules on the film rolling rob 4 by volume film clamping; Film rolling arm sleeve 6 is cylindricality, and the middle part is hollow, and one group of bearing 8 is two, lays respectively at the hollow part of film rolling arm sleeve 6, links to each other by bearing connecting axle 9 between two bearings 8, and bearing 8 can move around along axis direction in film rolling arm sleeve 6; Film rolling arm expansion link 7 is positioned at film rolling arm sleeve 6 hollow part, and an end of film rolling arm expansion link 7 connects film rolling rob 4 by universal ball joint, and on bearing connecting axle 9, film rolling arm sleeve 6 connects motor 5 to the other end by bolt.

In the utility model, bearing 8 is the 1-3 group.

In the utility model, the cross section of film rolling arm sleeve 6 is rectangular.

The utility model course of work is as follows:

When motor 5 gets electric work, the output torque of motor passes to film rolling arm sleeve 6 by universal ball joint and makes its rotation, the rotation of film rolling arm sleeve 6, its moment of torsion can be delivered on the bearing connecting axle 9 by two pairs of bearings 8, and the rotation of bearing connecting axle 9 also drives film rolling arm expansion link 7 simultaneously and rotates.In the volume membrane process, when making that because of movement locus film rolling arm expansion link 7 needs to stretch, the axial thrust load that acts on the film rolling arm expansion link 7 will act on the bearing 8 by bearing connecting axle 9, make bearing 8 to move in film rolling arm sleeve 6, and realize Telescopic.The rotation of volume film expansion link 7 passes to film rolling rob 4 by universal ball joint with moment of torsion, thereby makes film rolling rob 4 roll the insulation film made 1 in greenhouse, and moves along bow member 2 profiles.

Characteristics of the present utility model are:

(1) greenhouse volume film moment of torsion transmission telescopic mechanism can be realized freely stretching when transmitting moment of torsion, and this has reduced the requirement to little shed bow member systematicness, and applicable surface is wider.Also greatly reduce simultaneously Unit Installation precision such as motor-driven.

(2) for some length long simple and easy daylight plastic greenhouse and little shed, though load is heavier, because of bearing is rolling friction with film rolling arm sleeve groove, coefficient of friction is little, and stretching of film rolling arm expansion link is also more smooth and easy.
