Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a leak-proof fuel tank device for garden plant protection machinery. Background Technology

[0002] Garden plant protection machinery, such as sprayers and pesticide sprayers, is widely used in garden maintenance and crop protection operations. As the core oil storage component of the machinery, the fuel tank stores oil for the machinery. However, when refueling existing garden plant protection machinery fuel tanks, fuel is prone to overflowing from the gap between the refueling nozzle and the inlet pipe due to the large gap. This not only wastes fuel but also pollutes the environment and may even cause safety hazards. In addition, it is difficult to control the amount of fuel added to the tank, and fuel can easily overflow due to overfilling. There is also a lack of a visual indicator for the fuel level.

[0013] 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.

[0014] Please see Figure 1-3 This utility model provides a technical solution: In this technical solution, a drip-proof garden plant protection machinery oil tank device includes an oil tank body 1, an oil inlet pipe 2 is provided on the upper wall of the oil tank body 1, and an oil tank cover 3 is screwed into the oil inlet pipe 2. The oil inlet pipe 2 includes a pipe body 21, an overflow hole 22, a liquid storage pipe 23, a plug 24, and a rubber ring 25. The pipe body 21 is inserted into the upper wall of the oil tank body 1. An overflow hole 22 is provided on the side wall of the pipe body 21. A liquid storage pipe 23 is inserted into the overflow hole 22. The liquid storage pipe 23 is a transparent pipe body. A plug 24 is inserted into the end of the liquid storage pipe 23 away from the pipe body 21. A rubber ring 25 is installed on the inner side wall of the pipe body 21. The rubber ring 25 can fit against the side wall of the external refueling gun. In this technical solution, the pipe body 21 is directly welded to the main body 1 of the fuel tank. When refueling, the fuel tank cap 3 can be opened, and then the refueling nozzle can be inserted into the pipe body 21. At this time, the rubber ring 25 can wrap around the refueling nozzle to seal the gap between the refueling nozzle and the pipe body 21, thereby preventing fuel leakage during refueling and avoiding fuel waste. The overflow hole 22 can guide excess fuel into the reservoir pipe 23 when the fuel tank is overfilled, preventing fuel from overflowing directly. The transparent reservoir pipe 23 allows operators to visually observe the internal fuel level, enabling them to stop refueling in a timely manner.

[0015] In some technical solutions, a convex ring 4 is installed on the inner side wall of the rubber ring 25. The convex ring 4 is made of rubber, and at least two convex rings 4 are provided. Both convex rings 4 can fit against the outer wall of the external refueling gun.

[0016] In this technical solution, because the convex ring 4 is made of rubber, it can deform. After the fuel nozzle is inserted, the convex ring 4 can bend downwards, thus tightly fitting the outer wall of the fuel nozzle and forming multiple sealing barriers. Compared with a single sealing surface, this greatly improves the sealing reliability and further reduces the possibility of fuel leakage from gaps.

[0017] In some technical solutions, the liquid storage tube 23 includes a first connecting tube 231, a second connecting tube 232, a locking nut 233, a limiting ring 234, and a sealing gasket 235. One end of the first connecting tube 231 is inserted into the overflow hole 22, and the other end of the first connecting tube 231 is fitted with the second connecting tube 232. The plug 24 is inserted into the second connecting tube 232. The outer side of the first connecting tube 231 is provided with external threads. The locking nut 233 is rotated and installed on the outer side of the first connecting tube 231. The locking nut 233 can fit against the outer wall of the tube body 21. The limiting ring 234 is installed on the outer side of the end of the first connecting tube 231 located inside the tube body 21. The sealing gasket 235 is fitted against the side wall of the limiting ring 234 and fits against the inner wall of the tube body 21.

[0018] In this technical solution, the first connecting pipe 231 is inserted into the overflow hole 22. The first connecting pipe 231 is made of stainless steel, and the second connecting pipe 232 is made of transparent acrylic material, providing storage space for fuel. The two work together to form a complete overflow storage channel. The locking nut 233 cooperates with the limiting ring 234. By tightening the locking nut 233, the first connecting pipe 231 can be firmly fixed to the pipe body 21. At the same time, the sealing gasket 235 fits against the inner wall of the pipe body 21, which can fill the gap between the first connecting pipe 231 and the overflow hole 22, preventing fuel from leaking from the connection gap.

[0019] In some technical solutions, fixing plates 5 are installed at both the front and rear ends of the lower wall of the main body 1 of the fuel tank. The upper wall of the fixing plate 5 is provided with a through hole 6, and a fixing bolt 7 is inserted into the through hole 6. The fixing bolt 7 can be screwed into the fuel tank mounting bracket of the external garden plant protection machinery.

[0020] In this technical solution, the device can be fixed by inserting the fixing bolt 7 into the through hole 6 and screwing it into the oil tank mounting bracket of the external garden plant protection machinery. At the same time, after the fixing bolt 7 is tightened, a line can be drawn on its bolt head and the line can be drawn on the fixing plate 5. If the fixing bolt 7 becomes loose, the line segments will be staggered, making it easy to see and facilitate maintenance by the staff.

[0021] In some technical solutions, the outer wall of the fuel tank cap 3 is provided with anti-slip grooves 8.

[0022] In some technical solutions, a pad 9 is fitted to the side wall of the fuel tank body 1, a support plate 10 is installed on the side wall of the fuel tank body 1, a positioning hole 11 is opened on the side wall of the support plate 10, a positioning bolt 12 is inserted into the positioning hole 11, and the positioning bolt 12 can be screwed into the fuel tank mounting frame of the external garden plant protection machinery.

[0023] In this technical solution, the pad 9 is made of rubber and fits between the side wall of the tank body 1 and the mounting bracket. It can buffer the impact force of the collision between the tank body 1 and the mounting bracket during mechanical operation, reduce the wear between the two, and also reduce the noise generated by the collision. The support plate 10 cooperates with the positioning bolt 12 to be fixed from the side wall of the tank body 1, forming a three-dimensional fixing structure with the bottom fixing plate 5, further enhancing the installation stability of the tank body 1.

[0024] Working principle: Before the operation of the garden plant protection machinery, the oil tank is first fixed on the oil tank mounting frame of the machinery by the fixing plate 5 and fixing bolt 7 on the lower wall of the oil tank body 1. Then, the side wall support plate 10 and positioning bolt 12 are used for secondary reinforcement. The pad plate 9 buffers the collision between the oil tank and the mounting frame. When refueling, unscrew the fuel tank cap 3 and insert the external refueling nozzle into the pipe body 21 of the fuel line 2. The rubber ring 25 on the inner side of the pipe body 21 and the convex ring 4 are tightly fitted against the outer wall of the refueling nozzle to form multiple seals to prevent fuel leakage. As fuel is injected, when the fuel level in the fuel tank body 1 reaches the height of the overflow hole 22, the excess fuel flows into the first connecting pipe 231 through the overflow hole 22 and then into the second connecting pipe 232. The operator can stop refueling after observing the fuel through the transparent first connecting pipe 232 to avoid overflow. After refueling is completed, pull out the refueling nozzle and tighten the fuel tank cap 3.
