Abstract

The utility model relates to a folding external sun-shielding driving device of a greenhouse, which is composed of an external sun-shielding framework of a greenhouse and a driving unit device on the framework, wherein the external sun-shielding framework of a greenhouse is formed by overlapping external sun-shielding upright posts, east-west transverse beams and north-south transverse beams firmly. The driving unit device comprises a driving motor fixed on the transverse beams; a driving gear of a gear-rack bar transmission mechanism is linked with the motor by an internal sleeve transmission shaft, and a driven gear is engaged with a rack bar which is fixedly connected with a push-pull rod which can move longitudinally by a connecting piece of the rack bar; a plurality of proper positions on the push-pull rod are fixedly connected with driving edge sections which support the movable edge of a sun-shielding curtain, and push-pull rod support members are arranged on the transverse beam movably crossed with the push-pull rod. The structure of the utility model is reasonable, and the sun-shielding curtain after furled can be folded up with small sun-shielding area; when the sun-shielding curtain is furled or unfurled by the device, stainless steel rings are slid on a load bearing curtain line to prevent a net body of the sun-shielding curtain from being worn out, and prolong the service life of a sun-shielding net.

Description

The collapsible external sunshade drive unit in greenhouse

Technical field

The utility model relates to the collapsible external sunshade drive unit in a kind of greenhouse.

Background technology

Now be used for the collapsible external sunshade device in greenhouse and mostly be direct push-and-pull stacking.This kind mode shortcoming is: the locator card silk must be housed in the mounting structure or play the structural member of same function with it, and the locator card silk comes off easily through after a while round operation in actual application, after this structure comes off, in driving section bar push-and-pull process, the curtain leakage will occur and push away phenomenon.Mode is stacked in the direct push-and-pull of this kind simultaneously, sunshade dictyosome easy to wear, and overall aesthetics is relatively poor.

Summary of the invention

The purpose of this utility model provides the collapsible external sunshade drive unit in a kind of easy to use, durable greenhouse, and it is little to utilize this device can realize that the sunshade curtain acts freely, draws in the back area occupied.

For achieving the above object, the utility model is taked following design: the collapsible external sunshade drive unit in this greenhouse, constitute by greenhouse external sunshade skeleton and driver element device placed on it, described greenhouse external sunshade skeleton is firmly to be overlapped by external sunshade column, East and West direction crossbeam and north-south crossbeam to constitute, and described driver element device comprises: one is fixed on the drive motors on the crossbeam; Its output shaft is by the gear-rack gear of some chain wheel set, the corresponding group of propeller shaft couplings; Described gear-rack gear, its driving gear passes through interior looper drive shaft and motor linkage, its driven gear toe joint tooth bar, tooth bar is affixed with the pull bar that can vertically move by the tooth bar connector; The fixedly connected driving limit section bar of accepting sunshade curtain active edges in the some appropriate positions of pull bar.

For make the pull bar moving direction accurately, advance smooth and easyly, move at pull bar and to put the pull bar support member on the crossing crossbeam.

The utility model has the advantages that: reasonable in design, the sunshade curtain can be drawn in the back folding neat, the area that shades is little; And during by this device folding and unfolding sunshade curtain, only by sliding on the stainless steel suspension ring load-bearing curtain line, ante-venna cloth dictyosome is not frayed, prolongs the service life of sunshade net.

Embodiment

The collapsible external sunshade drive unit in the utility model greenhouse is made of greenhouse external sunshade skeleton and driver element device placed on it.

As Fig. 1-A, shown in Fig. 1-B, described greenhouse external sunshade skeleton is by some external sunshade columns 1, East and West direction crossbeam 8 and north-south crossbeam 16 firmly overlap joint constitute, described driver element device comprises: one is fixed on drive motors 19 on the crossbeam (referring to Fig. 4-A, Fig. 4-B), its output shaft is by some chain wheel set 20,21, power transmission shaft 22 connects the gear-rack gear of corresponding group, gear combination 10 critical pieces of this gear-rack gear have clamping plate 10-01, driven gear 10-02, driving gear 10-03, nylon wheel 10-04, the assembling details is seen Fig. 2-A, Fig. 2-B, driving gear is by interior looper drive shaft 22 and motor linkage, its driven gear toe joint tooth bar 12; Described tooth bar 12 is affixed with the pull bar 11 that can vertically move by tooth bar connector 5; The fixedly connected driving limit section bar 2 of accepting sunshade curtain active edges in the some appropriate positions of pull bar.

Move at pull bar and to put the pull bar support member on the crossing crossbeam, this support member is roller mount and roller, pull bar supports with roller mount 17 ' at middle part, whole greenhouse, supports with limit roller 17 at whole greenhouse canopy head (about 4 meters standard width of a room in an old-style house places) that (the assembling details is referring to Fig. 3-A, Fig. 3-B).

Have the caulking groove of ccontaining sunshade curtain hanger on the section bar of described driving limit.

Have deceleration device in the described gear drive.

Fig. 5, Fig. 6, Fig. 7 are the structural representation with the ante-venna combination.Fig. 5 is positioned at canopy head orientation fixed edge assembly drawing, and wherein ante-venna 23 hangs on the load-bearing curtain line 13 by curtain suspension ring 26, and fixed edge is fixed in the draw-in groove 24 by thick jump ring 25.Fig. 6 is a fixedly assembly drawing of middle part, greenhouse ante-venna, and wherein fixed edge is identical with fixed form among Fig. 5, and active edges is fixed in the caulking groove that drives limit section bar 2 by thin jump ring 27.Play the sunshade effect when whole curtain launches, curtain is just folded up facing mutually between two suspension ring respectively when packing up, and forms collapsible external sunshade (details is installed sees Fig. 7).
