Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, the greenhouse plastic film retracting device includes a housing 1 and a guide rod 3. The housing 1 is movably nested on the vertical guide rod 3. The inside of the housing 1 is provided with a gear transmission mechanism. One end of the gear transmission mechanism A rocking handle 2 is connected, and the other end of the gear transmission mechanism is connected with a horizontal plastic film retracting rod 5 . The gear transmission mechanism comprises a first gear 8, a second gear 9 and a third gear 10 which are externally engaged in sequence, the axle of the first gear 8 is connected with the crank handle 2, and the axle of the third gear 10 is connected with the crank handle 2. The plastic film retracting rod 5 is connected.

[0015] In the gear transmission mechanism, the diameter of the first gear 8 is larger than the diameter of the third gear 10 . Every time rocking handle 2 rotates one week like this, plastic film retrac...

Abstract

A greenhouse plastic film reeling and unreeling device belongs to agricultural tools. The greenhouse plastic film reeling and unreeling device comprises a housing and a guide rod, wherein the housing is movably sleeved outside the vertical guide rod, a gear transmission mechanism is arranged inside the housing, one end of the gear transmission mechanism is connected with a rocking handle, and the other end of the gear transmission mechanism is connected with a horizontal plastic film reeling and unreeling rod. The greenhouse plastic film reeling and unreeling device can achieve the reeling and unreeling of greenhouse plastic film, is convenient and labor-saving and reduces the labor intensity.

Description

technical field [0001] The invention relates to an agricultural tool used in a greenhouse, in particular to a greenhouse plastic film retracting device. Background technique [0002] Greenhouses have developed rapidly since their appearance. In order to meet people's needs for different purposes, greenhouses are no longer limited to a single type of traditional earth wall, but are increasingly diversified. Some plastic greenhouses need to roll up the plastic film when the outside sun is good and the temperature is high, so as to realize the needs of ventilation and temperature adjustment in the shed, and at night or when the temperature is low, the plastic film needs to be rolled down to maintain the temperature inside the shed. at an appropriate level. At present, most of the retracting and retracting of plastic films is done manually, which is not only labor-intensive, but also easily damages the plastic film when retracting and retracting manually. Contents of the inve...
