Back-rolled straw-covered agricultural greenhouse

Abstract

The invention provides a back-rolled straw-covered agricultural greenhouse, comprising a straw cover, a winding shaft, a winding rope, a pulley, a winch, a fixing rod and a straw cover frame and characterized in that the greenhouse straw cover is linked by the winding shaft and is rolled from top to bottom through the winding rope, the pulley and the winch and then placed on the straw mat frame; the straw cover is spread from top to bottom and fixed to a roof of the greenhouse; compared with the prior art, the greenhouse has the rolled straw cover placed on the straw cover frame in the open space of the greenhouse, load to be carried by the greenhouse is relieved, damage from wind resistance to the straw mat rolled up high and suspended to the roof is avoided, a shadow area due to the straw cover being rolled and blocking light is eliminated, the risk and trouble are avoided for roof cover rolling equipment or staff, the greenhouse has the advantages of good safety and convenience of operation, narrow shadow area, good stability of pacing the straw cover, low land consumption and the like and accordingly is well worthy of popularization and application.

Description

1. Technical field: [0001] The invention provides an agricultural greenhouse for rolled thatch quilts, which belongs to agriculture. 2. Background technology: [0002] Thatch is an important measure to keep warm and insulate the light and heat film area of ​​agricultural greenhouses during non-sunlight periods. In the prior art, the covering and rolling off of the lower thatch are still done by the gravity of the thatch, rolling down from top to bottom, and pulling and rolling off with ropes from bottom to top. However, this traditional method exists There are many defects and disadvantages, mainly as follows: 1. The rolled up thatch is placed on the roof of the shed, which increases the load of the greenhouse, and the greenhouse needs to be provided with stronger support. scattered, causing a lot of trouble and loss. 2. The thatch is placed on the roof of the shed, which expands the shadow area of ​​the shed and affects the lighting of the back to the shed. To avoid this ...

Problems solved by technology

In the prior art, the covering and rolling off of the lower thatch are still done by the gravity of the thatch, rolling down from top to bottom, and pulling and rolling off with ropes from bottom to top. However, this traditional method exists There are many defects and disadvantages, mainly as follows: 1. The rolled up thatch is placed on the roof of the shed, which increases the load of the greenhouse, and the greenhouse needs to be provided with stronger support. scattered, causing much trouble and loss

2. The thatch is placed on the roof of the shed, which expands the shadow area of ​​the shed and affects the lighting of the back to the shed. To avoid this effect, it is necessary to increase the distance between the sheds and cause land waste

3. The thatch is rolled up, whether it is done by mechanical control or manpower, the facilities or personnel are mostly set up on the roof, which has more difficulties, risks and troubles
