Description

Technical Field

[0001] This utility model relates to the field of grain planting technology, specifically to a pesticide sprayer for grain planting. Background Technology

[0002] In the process of grain cultivation, pest and disease control is a key link in ensuring grain yield and quality, and pesticide spraying is an important means of pest and disease control.

[0003] Small sprayers have limited capacity. For example, the common backpack sprayer requires frequent trips to the refill point to add pesticides when used in large-scale farmland, which wastes time and affects work efficiency. Therefore, we propose a pesticide sprayer for grain planting. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide sprayer for grain cultivation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pesticide sprayer for grain planting, comprising a backpack basket, a handheld sprayer, and a pesticide storage box. A pump body is fixedly connected to the side of the handheld sprayer tube wall near the backpack basket. An opening is provided at the lower end of the backpack basket wall. L-shaped baffles are fixedly connected at the included angle of the bottom of the backpack basket. An elastic hose is connected to the input end of the handheld sprayer tube wall. A fixing ring is fixedly connected to the wall of the elastic hose. A rotating ring is rotatably embedded in the fixing ring. A limiting sleeve is fixedly connected to the wall of the rotating ring. A rubber ring is fixedly connected to the inner end of the elastic hose tube wall located within the limiting sleeve. A pesticide outlet tube is embedded at the lower end of the pesticide storage box wall, and the outer wall of the pesticide outlet tube is threadedly connected to the inner wall of the limiting sleeve.

[0006] Preferably, a basket cover is hinged to the upper end of the outer wall of the basket, and carrying straps are fixedly connected to both sides of the basket wall.

[0007] Preferably, the outer diameter of the medicine storage box matches the inner diameter of the four L-shaped baffles.

[0008] Preferably, the flexible hose is located at the inner end of the opening, and the length of the dispensing tube wall is less than the inner diameter of the basket.

[0009] Preferably, the inner wall of the limiting sleeve is provided with an internal thread, and the outer wall of the dispensing tube is provided with an external thread.

[0010] Compared with existing technologies, the advantages of this invention are as follows: the pesticide outlet pipe of the storage tank is connected to the limiting sleeve via a thread, and during the connection process, a rubber ring is inserted into the outlet pipe, resulting in a tight connection and easy assembly and disassembly. Operators can quickly change the storage tank, reducing operational difficulty and improving work convenience. The pre-equipped storage tank, which can be quickly assembled, greatly improves the efficiency of pesticide spraying operations. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: A pesticide sprayer for grain planting includes a backpack basket 1, a handheld sprayer 2, and a pesticide storage box 3. A pump body 21 is fixedly connected to the side of the handheld sprayer 2 near the backpack basket 1. A basket cover 11 is hinged to the upper end of the outer wall of the backpack basket 1. Shoulder straps 12 are fixedly connected to both sides of the backpack basket 1.

[0019] When using it, first open the basket cover 11 and place the medicine storage box 3 inside the backpack 1. Then, the staff will carry the backpack 1 on their back using the shoulder straps 12. Then, they will pick up the handheld sprayer 2 and start the pump body 21 to spray different locations.

[0020] Example 2: The technical solution of this example, which differs from that of Example 1, includes: an opening 101 at the lower end of the basket wall of the back basket 1; L-shaped baffles 13 fixedly connected to the included angle of the bottom of the back basket 1; an elastic hose 22 connected to the input end of the handheld sprayer 2; a fixed ring 23 fixedly connected to the wall of the elastic hose 22; a rotating ring 24 rotatably embedded in the fixed ring 23; a limiting sleeve 25 fixedly connected to the wall of the rotating ring 24; a rubber ring 26 fixedly connected to the inner end of the elastic hose 22 within the limiting sleeve 25; a dispensing pipe 31 embedded at the lower end of the wall of the medicine storage box 3; the outer wall of the dispensing pipe 31 threadedly connected to the inner wall of the limiting sleeve 25; the outer diameter of the medicine storage box 3 matching the inner diameter of the four L-shaped baffles 13; the elastic hose 22 located inside the opening 101; and the length of the dispensing pipe 31 wall being less than the inner diameter of the back basket 1; an internal thread on the inner side wall of the limiting sleeve 25; and an external thread on the outer wall of the dispensing pipe 31.

[0021] In use, when the medicine storage box 3 is placed between the four L baffles 13, the staff holds the elastic hose 22, and the rubber ring 26 is inserted into the medicine outlet tube 31. Then, the limiting sleeve 25 is rotated along the fixed ring 23 through the rotating ring 24. At this time, the limiting sleeve 25 can be connected to the medicine outlet tube 31 by rotating. It is easy to assemble and disassemble. In contrast, frequently returning to the medicine dispensing point to continue adding medicine will waste a lot of time. By replacing the medicine storage box 3 in time, the time can be greatly saved, thereby improving work efficiency.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
