Description

Technical Field

[0001] This utility model relates to a fertilization and irrigation device for an automated agricultural seedbed logistics system, and more particularly to a height-adjustable component for a sprinkler irrigation machine. Background Technology

[0002] As society continues to develop, people are paying more and more attention to the health and environmental protection of their living environment. In modern urban construction planning, ecology, greening, and pure green vegetables are gradually being given top priority. Society needs a large number of seedlings, and the seedling industry has sprung up accordingly. Cultivating good seedlings requires professional technology and a suitable environment, as well as high-quality seedbeds. Through the agricultural automated seedbed logistics system, seedling production can be made more efficient and convenient in the era of modern agricultural intelligent technology. This system includes multiple seedbeds set up in greenhouses, as well as a variety of supporting facilities for the seedbeds.

[0003] The sprinkler irrigation machine, driven by an electric motor, is a device for fertilizing and irrigating crops in greenhouse seedbeds. It employs fully automatic control, with a control system managing its operation and coordinating greenhouse irrigation for automated operation. However, existing sprinkler irrigation machines, operating at different stages of crop growth, have the following drawbacks:

[0004] (1) The distance between the sprinkler head and the seedbed is fixed. When the crop has just sprouted, the distance between the sprinkler head and the seed tray placed in the seedbed is about 300mm. The water pressure of the sprinkler head is relatively high, a large amount of substrate is washed away, and the seeds are exposed, which is not conducive to seedling cultivation.

[0005] (2) As the crop grows to a certain stage, the distance between the sprinkler head and the seedling tray remains unchanged at about 300mm. The top of the crop will be scratched by the sprinkler, resulting in a lot of losses and making seedling cultivation even more difficult. Utility Model Content

[0006] This utility model provides a height-adjustable component for a sprinkler irrigation machine, which solves the problem that the height of the sprinkler irrigation machine can be adjusted at any time according to the actual needs of the crop, ensuring stable operation. The technical solution is as follows:

[0007] An adjustable height component for a sprinkler irrigation machine is disclosed. The upper part of the adjustable height component is fixedly connected to the main traveling body of the sprinkler irrigation machine, and the lower part is fixedly connected to the main irrigation body of the sprinkler irrigation machine.

The bottom of the support rod is fixedly connected to the main body of the sprinkler irrigation machine. The horizontally arranged extension rod at the top is connected to the trapezoidal lead screw through the first lead screw support. The trapezoidal lead screw, from top to bottom, is first connected to the lifting frame through the trapezoidal lead screw nut, passes through the opening of the first connecting frame, and then is connected to the second connecting frame through the second lead screw support. A solid handwheel is installed at the bottom. By rotating the solid handwheel, the trapezoidal lead screw rotates, causing the trapezoidal lead screw nut to move up and down, thereby causing the lifting frame to move up and down.

[0009] The top of the support rod is provided with a horizontally arranged extension rod, and the extension rod is provided with a first lead screw support. The first lead screw support is connected to the top of the trapezoidal lead screw through a first bearing. The bottom of the support rod is fixed to the sleeve of the sprinkler body of the sprinkler irrigation machine through a flange. Below the sleeve, it is fixedly connected to the connecting frame through a flange.

[0010] The first lead screw support includes a first support body, with first support threaded holes around the perimeter of the first support body, which are fixedly connected to the extension rod by bolts; a first support bearing is provided in the middle of the first support body, the inner ring of the first support bearing is fixedly connected to the top of the trapezoidal lead screw, and the outer ring of the first support bearing is fixedly connected to the first support body.

[0011] The trapezoidal lead screw is divided into a top, a body, a shaft, and a bottom from top to bottom. The top of the lead screw is rotatably connected to the support rod via a lead screw support. The body of the lead screw is rotatably connected to the trapezoidal lead screw nut. The part located below the trapezoidal lead screw nut passes through the opening of the first connecting frame. The shaft is rotatably connected to the second connecting frame via a lead screw support. The bottom of the lead screw is fixedly connected to a solid handwheel.

[0012] The trapezoidal lead screw nut includes a nut body, a nut ring at the bottom of the nut body, nut openings at the four corners at the top, and a threaded opening in the middle.

[0013] The second lead screw support includes a second support body, with threaded holes at the four corners of the upper part of the second support body, a second support ring at the lower part, and a second support bearing in the middle; the second connecting frame has a through hole, through which the second support ring passes, and the second lead screw support is fixed to the second connecting frame by the second support body and bolts; the second support bearing cooperates with the lead screw shaft of the trapezoidal lead screw to realize the rotational connection between the second lead screw support and the trapezoidal lead screw.

[0014] The solid handwheel includes a handwheel body, an opening in the middle of the handwheel body, and a detachable fixed connection to the bottom of the trapezoidal lead screw. A handle is provided on the side of the handwheel body.

[0015] The main body of the sprinkler irrigation machine includes a sprinkler frame and a steel wire rope. The bottom of the support rod is fixedly connected to the sprinkler frame, and the sprinkler frame is also connected to the first connecting frame via the steel wire rope.

[0016] The main body of the sprinkler irrigation machine is equipped with a water spray pipe, which is connected to the sprinkler irrigation support through a water supply pipe. The sprinkler irrigation support is equipped with multiple nozzles.

[0017] The height-adjustable component of the sprinkler irrigation machine addresses the deficiency of existing sprinkler irrigation technology where the automated operation height is not adjustable. It allows the sprinkler irrigation machine to adjust its height according to actual needs and crop height, ensuring stable operation. The adjustable height of the component is 600mm, ensuring the distance between the sprinkler head and the seedbed ranges from 85mm to 685mm, maintaining the optimal distance for irrigation or fertilization of seedlings.
