Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to a novel spraying device for the mid-to-late stage management of tall crops. Background Technology

[0002] Late-stage management of corn can improve the effectiveness of prevention and control. During this period, the root system of corn may gradually decline, reducing its absorption capacity and making it susceptible to diseases such as ochryma-jobi, corn borers, and corn worms. Timely application of foliar fertilizers, growth regulators, stress-resistant agents, insecticides, fungicides, and pesticides at this time can increase photosynthesis and pest control, leading to increased yield, income, and improved quality.

[0003] Existing sprayers, such as the new type of shoulder-mounted sprayer for crop pest control mentioned in Chinese patent CN202121340388.1, still have the following defects when in use: they cannot adapt to the user's height when spraying tall crops, and spraying tall crops in the middle and later stages is difficult. In addition, existing sprayers cannot adjust the spray width. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a new type of spraying device for the mid-to-late stage management of tall crops, so as to solve the defects of existing sprayers that cannot adjust the height and width.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a novel spraying device for mid-to-late stage management of tall crops, including a first telescopic structure installed on a sprayer. The first telescopic structure includes a first fixed rod and a first movable rod. A first knob for controlling the movement of the first movable rod is provided at the connection between the first fixed rod and the first movable rod. A hollow connecting rod is connected to the top of the first movable rod. A three-way pipe is fixedly connected to the other end of the connecting rod. A second telescopic structure for horizontal telescopic movement is connected to both sides of the three-way pipe. The second telescopic structure includes a second fixed rod and a second movable rod. A second knob for controlling the movement of the second movable rod is provided at the connection between the second fixed rod and the second movable rod. A nozzle is connected to the end of the second movable rod away from the second fixed rod.

[0006] Preferably, the end of the tee pipe that connects to the connecting rod is threaded with a conveying pipe.

[0007] Preferably, the sprayer is equipped with a shoulder strap, which is a Velcro strap that is easy to remove.

[0008] Preferably, the sprayer is equipped with a clamp, and the clamp is equipped with a retaining ring for fixing the first fixing rod.

[0009] The beneficial effects of this utility model are as follows: This utility model achieves multi-dimensional adjustment of spraying height and width through the combination design of the first telescopic structure and the second telescopic structure, which can be adapted to tall crops (such as corn) at different growth stages and the height of operators, thereby improving the accuracy of spraying.

[0010] The structure provided by this utility model is detachable, making it easy to carry and store, while reducing equipment costs and replacing expensive aerial spraying methods; the shoulder strap adopts a detachable solution such as Velcro, improving carrying comfort and operational flexibility, and is suitable for complex farmland environments.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example:

[0017] like Figures 1-3As shown, this utility model provides a novel spraying device for the mid-to-late stage management of tall crops, including a sprayer 1. The sprayer 1 is existing technology, and its specific structure will not be described in detail here. A first telescopic structure with longitudinal lifting is provided on one side of the sprayer 1. The first telescopic structure includes a first fixed rod 2 and a first movable rod 3. A first knob 4 for controlling the movement of the first movable rod 3 is provided at the connection between the first fixed rod 2 and the first movable rod 3. A connecting rod 5 is connected to the top of the first movable rod 3. The connecting rod 5 is hollow inside.

[0018] The other end of the connecting rod 5 is detachably connected to a three-way pipe 6, and the two sides of the three-way pipe 6 are connected to a second telescopic structure that extends laterally.
