Improved greenhouse overhead monorail self-propelled air-conveying spray rod sprayer

Abstract

The invention relates to the technical field of agricultural engineering, in particular to an improved greenhouse overhead monorail self-propelled air-conveying spray rod sprayer. The spraying rod sprayer comprises a driving device and driven traveling wheels, wherein the driving device and the driven traveling wheels are coupled and moved on a track consisting of a hanger rod suspended on a greenhouse frame and C-shaped steel; a lifting motor retracts and releases a steel wire rope through a double-groove rope pulley and controls the lifting movement of the air-conveying spray rod under the guidance of a moving pair consisting of a guide rod and a guide block; a centrifugal fan is connected with an air outlet pipe through a round local adapter and is provided with a spray head to form anair-conveying spray rod part; a group of spray heads are arranged under the two centrifugal fans to fill a spray blind area under the spray rod. A track formed by the C-shaped steel has high strength,low cost and good construction technology; the structure of the driving device is compact, and the structure of the lifting device is further simplified compared with a synchronous belt sliding tableor a chain transmission structure; the centrifugal fan spray rod is integrated, so that the air flow utilization efficiency and the air flow stability are improved, the effective spray width of the air-conveying spray rod is improved, and the penetration and deposition rate of spray operation are guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural engineering, in particular to an improved greenhouse single-suspension-rail self-propelled air-supplied boom sprayer. Background technique [0002] The row spacing of protected vegetable planting in my country is generally small, and the space between rows is further narrowed after the crops grow. In addition, the soil state between rows is complicated, which is not suitable for spraying machines between rows. The greenhouse rail sprayer moves above the crops without occupying the ground space, which improves the utilization rate of the greenhouse space. At the same time, the sprayer sprays from the center of the greenhouse to both sides above the crops. Compared with the track sprayer on the side of the shed, which sprays from the sidewalk on the side of the shed to the other side, the width of the spraying operation is halved, and the uniformity of droplet deposition is further improved.

Problems solved by technology

The main problems are as follows: First, the I-beam and its driving device are of high quality, high cost, and difficult to install and construct the track, which is not conducive to the application and promotion of the device; The advantages of precision, but the high cost and maintenance cost are not conducive to the application and promotion of the device; moreover, the air delivery system uses a fixed centrifugal fan, and the airflow is sent to the spray bar by the ventilation hose.

On the one hand, the airflow produces a loss along the ventilation hose, on the other hand, when the spray boom moves up and down, it will inevitably cause the bending of the ventilation pipe, further increasing the local loss of the airflow, and the hose is bent and straightened alternately, resulting in a change in the local airflow loss coefficient , which in turn makes the air pressure and flow rate unstable, thus affecting the spraying effect
