Greenhouse overhead rail type rope-driven pesticide spraying machine

Abstract

A greenhouse overhead rail type rope driven pesticide spraying machine belongs to the technical field of agricultural machinery. It comprises a first C-shaped steel track arranged on the back wall of a sunlight greenhouse, a second C-shaped steel track connected below the first C-shaped steel track and a third C-shaped steel track arranged on the front roof of the sunlight greenhouse. It does not occupy the space in the greenhouse, and improves the space utilization. The pesticide spraying device is connected with the two side tracks through a driving rope, and the design of the driving wheel set enables the pesticide spraying device to move arbitrarily in the same horizontal plane, which can greatly improve the pesticide spraying efficiency. At the same time, since the driving rope is used to drive the nozzle to move, the device is more portable and has low cost.

Compared with the traditional suspended pesticide spraying machine, it can be used while moving in the internal heat preservation greenhouse. The pesticide spraying machine has simple structure, low cost, is convenient to maintain and repair, can realize full-automatic control, improves the operation efficiency and saves labor.

Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and specifically relates to a greenhouse suspended rail type rope-driven sprayer. Background Technology

[0002] Currently, the most common types of sprayers for solar greenhouses are ground-rail type and overhead rail type. Ground-rail type is inexpensive, but has limited operating space and cannot operate between rows in the greenhouse. Overhead rail type is more flexible, but the installation of overhead rails and the equipment itself is expensive. Sprayers with central overhead rails cannot be used in greenhouses with internal insulation. Truss type sprayers with side overhead rails are large in size and expensive to manufacture. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a greenhouse suspended rail-mounted rope-driven sprayer.

[0004] The technical solution adopted in this invention is: a greenhouse suspended rail type rope-driven sprayer, the key technical points of which are: a first C-shaped steel rail set on the rear wall of the greenhouse, a second C-shaped steel rail connected below the first C-shaped steel rail, and a third C-shaped steel rail set on the front roof of the greenhouse; one end of a spraying water pipe slidably connected to the drive wheel set on the first C-shaped steel rail is inserted into a spraying tank, and the other end of the spraying water pipe is connected to a spring tube; the spring tube is wound around a drive rope located between the first C-shaped steel rail and the second C-shaped steel rail; the drive rope is connected to a spraying connector; the lower end of the spraying connector is connected to a spraying rod with a nozzle; the spraying connector is controlled to drive the nozzle to move under the traction force of the drive rope.

[0005] Furthermore, the drive wheel assembly includes a first drive wheel fixed at both ends of the first C-shaped steel rail, a first fixed pulley assembly consisting of a first fixed pulley and a fourth fixed pulley stacked together, a second drive wheel fixed at both ends of the third C-shaped steel rail, a second fixed pulley assembly consisting of a second fixed pulley and a third fixed pulley stacked together, a first movable pulley arranged along the first C-shaped steel rail, and a second movable pulley arranged along the third C-shaped steel rail.

[0006] Furthermore, the drive rope includes a first drive rope and a second drive rope. The first drive rope passes over the first drive wheel, turns through the first fixed pulley in the fixed pulley group, and then connects to the second fixed pulley. After turning through the second movable pulley, it connects to the first connecting end of the spraying joint. The first drive rope passes through the third connecting end of the spraying joint, passes over the first movable pulley, turns through the first movable pulley, and then connects back to the first drive wheel. The second drive rope passes over the second drive wheel, turns through the second movable pulley, and then connects to the fourth connecting end of the spraying joint. The second drive rope passes through the second connecting end of the spraying joint, passes over the first movable pulley, turns through the third fixed pulley in the fixed pulley group, and then connects to the fourth fixed pulley in the fixed pulley group. The second drive rope returns to the second drive wheel after passing through the fourth fixed pulley.

[0007] Furthermore, a track hanger is slidably connected inside the second C-shaped steel track, and a spray pipe is suspended at the lower end of the track hanger. The beneficial effects of this invention are as follows: This greenhouse suspended rope-driven sprayer includes a first C-shaped steel track installed on the rear wall of the greenhouse, a second C-shaped steel track connected below the first C-shaped steel track, and a third C-shaped steel track installed on the front roof of the greenhouse. It does not occupy space inside the greenhouse, thus improving space utilization. The spraying device is connected to the tracks on both sides via a drive rope. The design of the drive wheel set allows the spraying device to move freely within the same horizontal plane, greatly improving spraying efficiency. Furthermore, the use of a drive rope to move the nozzle makes the device lighter and less expensive. The nozzle can move freely within a plane, enabling automatic spraying. Compared to traditional suspended sprayers, it can be used while moving within an insulated greenhouse. This sprayer has a simple structure, low cost, and is easy to maintain and repair. It can achieve fully automatic control, improving work efficiency and saving labor. Attached Figure Description
