Technical Field

[0001] This utility model relates to the field of pesticide application pole technology, and in particular to a lightweight telescopic tall crop pesticide application pole. Background Technology

[0002] In the later stages of growth of tall crops, the plant height can usually reach more than 2 meters. Traditional spraying methods have many drawbacks. For example, the fixed length of the spraying pole cannot adapt to the height changes of crops at different growth stages. For taller crops, operators need to lift them with great effort or use props, which makes spraying difficult, labor-intensive and poses safety hazards. In addition, traditional long pole-shaped agricultural tools take up a lot of space, and storage and field transportation during the off-season are extremely inconvenient.

[0003] To address the aforementioned issues, this invention provides a lightweight telescopic tall crop spraying pole. Summary of the Invention

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6This utility model provides a technical solution for a lightweight telescopic tall crop spraying pole: The lightweight telescopic tall crop spraying pole includes a handle 1 and a first section 3 connected to one end of the handle 1. A second section 4 is inserted into the first section 3, and a third section 5 is inserted into the second section 4. The first section 3, the second section 4, and the third section 5 together form a telescopic pole body. The material can be made of aluminum alloy or carbon fiber composite material to achieve the design requirements of lightweight and high strength. The rear end of the handle 1 is connected to a pesticide tube connector 2 for connecting to the outlet of an external pesticide tank through a flexible tube. The handle 1, the first section 3, the second section 4, and the third section 5 are all provided with pesticide channels 7, and the pesticide channels 7 inside the handle 1, the first section 3, the second section 4, and the third section 5 are interconnected to ensure smooth pesticide delivery.

[0018] One end of the third rod 5 is connected to a spray nozzle 6. An adjustable component is provided between the third rod 5 and the spray nozzle 6. The adjustable component includes a connecting seat 61 fixed to one end of the third rod 5. A ball groove is opened on one end face of the connecting seat 61, and a hinge ball 62 is movably embedded in the ball groove. A connecting rod 63 is vertically arranged on the hinge ball 62. The other end of the connecting rod 63 is connected to the spray nozzle 6. A locking screw 65 is threaded to the outside of one end of the connecting seat 61. One end of the locking screw 65 is screwed into the ball groove and abuts against the surface of the hinge ball 62 to fix the nozzle angle.

[0019] The outer surface of the third section rod 5 near the connecting seat 61 is also provided with a medicine outlet, which is connected to the medicine liquid channel 7 inside the third section rod 5. The medicine outlet is connected to one end of the spray nozzle 6 through the connecting hose 64. The spray nozzle 6 adopts a standard interface, supports the replacement of nozzles with different atomization effects, and integrates an adjustable flow valve to adapt to the needs of different agents and crops. The first section of rod 3 has symmetrically symmetrically arranged positioning holes 31 on one end surface, and the second section of rod 4 has two sets of spring protrusions 41 on both ends surface, with each set consisting of two symmetrical spring protrusions 41. Figure 3 For example, when the second rod 4 is fully retracted into the first rod 3, the two spring protrusions 41 on the second rod 4 away from the rubber piston 42 will be engaged in the positioning hole 31. Conversely, when it is fully extended, the spring protrusions 41 on the second rod 4 near the rubber piston 42 will be engaged in the positioning hole 31. The telescopic fixing principle of the third rod 5 is the same.

[0020] The surface of the second rod 4 has a groove corresponding to the spring protrusion 41, and a spring is installed in the groove. One end of the spring is fixed to the inner wall of the groove, and the other end is connected to the spring protrusion 41. The outer diameter of the spring protrusion 41 is adapted to the inner diameter of the positioning hole 31. The second rod 4 slides and extends within the first rod 3 and is fixed by being engaged in the positioning hole 31 by the spring protrusion 41, thus achieving self-locking fixation after the rod body extends and retracts.

[0021] The second rod 4 has symmetrically arranged positioning holes 43 on one end surface, and a rubber piston 42 is fixed to the other end of the second rod 4. The outer diameter of the rubber piston 42 is adapted to the inner diameter of the first rod 3. The rubber piston 42 is a hollow through-type structure and is connected to the liquid channel 7 inside the second rod 4 and the first rod 3. It should be noted that the rubber piston 42 and the rubber piston 52 can form a sealing structure inside the first rod 3 and the second rod 4 to prevent liquid leakage.

[0022] Two sets of spring protrusions 51 are provided on the two ends of the third rod 5. There are two spring protrusions 51 in each set and they are symmetrical to each other. The structure of the spring protrusions 51 is the same as that of the spring protrusions 41. The outer diameter of the spring protrusions 51 is adapted to the inner diameter of the positioning hole 43. The third rod 5 slides and extends in the second rod 4 and is fixed by being inserted into the positioning hole 43 by the spring protrusions 51. A rubber piston 52 is fixed at one end of the third rod 5. The outer diameter of the rubber piston 52 is adapted to the inner diameter of the second rod 4, and the rubber piston 52 is a hollow through-type structure, which is connected to the medicine channel 7 inside the third rod 5 and the second rod 4.

[0023] The working principle of this utility model is as follows: the medicine tube connector 2 at the rear end of the grip handle 1 is connected to the medicine outlet of the external medicine box through a hose, and the medicine liquid enters the telescopic rod body through the medicine liquid channel 7 inside the grip handle 1. When adjusting the length of the telescopic rod, press the spring protrusion 41 against the spring force to make it exit the positioning hole 31, and then slide the second rod 4 to adjust the extension length. After releasing, the spring pushes the spring protrusion 41 into the corresponding positioning hole 31 to achieve fixation. The telescopic adjustment method of the third rod 5 is the same as that of the second rod 4. Locking is achieved by the cooperation of the spring protrusion 51 and the positioning hole 43. The angle of the spray nozzle 6 is adjusted by an adjustable component. Loosening the locking screw 65 allows the hinge ball 62 to rotate freely in the ball groove of the connecting seat 61, which in turn adjusts the spray nozzle 6 to the required angle of 0-90 degrees. (Within this angle range, it has been verified that it will not affect the normal conduction function of the connecting hose 64.) Then tighten the locking screw 65 to press it against the hinge ball 62 to fix the angle. The liquid medicine entering the liquid medicine channel 7 is finally delivered to the spray nozzle 6 through the outlet of the third rod 5 and the connecting hose 64. The nozzle with different atomization effects can be replaced as needed, and the liquid medicine flow rate can be controlled by the adjustable flow valve. In addition, rubber piston 42 and rubber piston 52 respectively ensure the sealing performance between the second rod 4 and the first rod 3, and between the third rod 5 and the second rod 4, to prevent leakage of the medicine.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
