Description

Technical Field

[0001] The present application relates to the technical field of greenhouse exhaust technology, and in particular to an auxiliary installation device for a double-layer air duct in a semi-enclosed greenhouse. Background Art

[0002] In recent years, in the Chinese market, in addition to the gradual popularization of multi-span greenhouses in the field of facility agriculture, there are also more and more semi-enclosed greenhouses.

[0003] Compared to multi-span greenhouses, semi-enclosed greenhouses utilize positive pressure ventilation systems, enabling more precise control of temperature, humidity, and CO2 concentrations. This is particularly beneficial in areas with more extreme climates, where these systems offer optimal control. Positive pressure ventilation systems utilize positive pressure fans and internal and external ducts to deliver air to the greenhouse, achieving ventilation. This makes the installation of these ducts a crucial step in the installation of semi-enclosed greenhouses.

[0004] The conventional installation of double-layer ducts in greenhouses generally relies on workers to drag the double-layer ducts and duct hanging wires together. Although the duct installation can be achieved, this installation method consumes a lot of manpower costs. Usually, the ducts in greenhouses are made of polyethylene film, the length is generally greater than 60m, and the weight is dozens of kilograms. During the duct installation process, the double-layer ducts need to be stacked together, and it is necessary to ensure that the inner and outer ducts cannot rotate or twist relative to each other, causing the duct outlet to be skewed and resulting in uneven air output. However, these requirements are difficult to achieve perfectly through manual operation alone. Utility Model Content

[0005] In view of this, the present application proposes a semi-enclosed greenhouse double-layer duct auxiliary installation device to improve work efficiency.

[0006] According to one aspect of the present application, a semi-enclosed greenhouse double-layer wind duct auxiliary installation device is provided, comprising a movable body made of aluminum alloy material, the body comprising: a support plate, a sleeve and a connecting piece;

[0009] The sleeve includes an inner sleeve and an outer air cylinder;

[0010] The sleeve passes through the connecting center hole and extends toward the front side of the vehicle body. The outer side of the inner sleeve is sleeved with the outer air duct.

[0011] In a possible implementation manner, the sleeve is disposed on the connecting member via a roller.

[0012] In a possible implementation, the inner sleeve and the outer air cylinder have the same direction and fold position.

[0013] In a possible implementation, the device further includes: a side support plate;

[0014] The side support plates are installed on both sides of the connecting member and extend toward the rear side of the vehicle body. The side support plates are parallel to the support plates.

[0016] The first support shaft and the second support shaft are made of stainless steel. The first support shaft and the second support shaft are installed between the side support plates and facilitate the installation of the sleeve.

[0017] In a possible implementation, the method further includes: fixing the shaft and the sleeve;

[0018] The fixed shaft is fixed between the side support plates and close to the connecting member, and is used to fix the side support plates;

[0019] The shaft sleeve is made of polyvinyl chloride material; the shaft sleeve is sleeved on the outside of the fixed shaft.

[0020] In a possible implementation, the inner sleeve has a hanging wire; the hanging wire is placed inside the inner sleeve, and one end of the hanging wire is fixed to the open end of the inner sleeve, and the other end of the hanging wire is fixed to the outer air duct.

[0021] In a possible implementation, the hanging wire passes through below the second support shaft, above the first support shaft, above the shaft sleeve, and the center hole.

[0022] In a possible implementation, the device further includes: a universal wheel assembly;

[0023] Several of the universal wheel assemblies are provided with brake structures and are installed at the bottom of the support plate to drive the vehicle body to move.

[0024] In a possible implementation, the connecting member and the side support plate, the connecting member and the first support shaft, the connecting member and the second support shaft, the connecting member and the fixed shaft, and the support plate and the universal wheel assembly are all welded.

[0025] The beneficial effects of the present application are as follows: by setting up a movable vehicle body, it is easy to move; setting up a connecting piece can fix the sleeve, reducing the error of manual operation and improving work efficiency.
