Description

Technical Field

[0001] The invention relates to the technical field of agricultural plungers, in particular to a multifunctional three-body high-pressure pump. Background Art

[0002] The three-body plunger pump is a kind of high-pressure pump. It has three plungers and three cylinders. It is an important device in the hydraulic system. The working principle is mainly to rely on the three plungers to perform reciprocating motion in the three cylinders to change the volume in the working chamber, thereby realizing the work of sucking and pressing liquid. The three-body plunger pump is mainly used in agriculture for high-pressure spraying or high-pressure irrigation due to its simple structure.

[0003] When the existing high-pressure pumps are in use, they are generally used in fields. When the high-pressure pumps are used for spraying or irrigating in these places, the supporting legs on the high-pressure pumps are usually placed on the ground. However, it is generally difficult to have a flat ground in these scenes, which makes it difficult to place the high-pressure pump stably. The vibration generated when the high-pressure pump is working will drive the pump to move in a tilted direction, or there is a possibility that the entire plunger pump will topple over. For this reason, there is a public technology on the market that provides a three-cylinder plunger pump with a stable supporting function, comprising a three-cylinder plunger pump body, a water inlet bin is fixed at one end of the three-cylinder plunger pump body, a filtering mechanism is arranged in the water inlet bin, and four supporting legs distributed in a rectangular shape are fixed to the three-cylinder plunger pump body, and an adjustment mechanism is arranged on the supporting legs. Place the three-cylinder plunger pump body in the required position, and then use the adjustment mechanism to adjust the height of the support legs to allow the three-cylinder plunger pump body to be placed stably. Use an external motor to drive the drive wheel to rotate. The water in the pool enters the water inlet tank through a water pipe. The filter mechanism of the water inlet tank filters the water drawn from the pool, so that the three-cylinder plunger pump body can be stably supported in the field, reducing the possibility of tilting or instability of the placement, and making the three-cylinder plunger pump body tip over when working;

[0004] Although the above-mentioned improved structure supports the plunger pump body by the support legs that can adjust the height separately, its supporting area is still too small. When the pumping pipe is pulled, there is still a possibility of tipping over. Moreover, the above-mentioned structure is not convenient to move when working on the field. There are also high-pressure pumps with small rollers on the market, but such rollers are usually small and are not convenient to move on the field. Therefore, it is necessary to optimize and improve a multifunctional three-body high-pressure pump structure. Summary of the invention

The anti-dropout pin 21 is set through the side wall of the wheel shaft sleeve 1601 and the axis of the anti-dropout pin 21 is perpendicular to the axis of the wheel shaft sleeve 1601. The end of the anti-dropout pin 21 extending to the outer wall of the anti-dropout pin 21 is fixedly connected with the pull ring 20. The convex ring 23 is set on the outer wall of the anti-dropout pin 21 and is located at the end away from the pull ring 20. The spring 22 is sleeved on the outer wall of the anti-dropout pin 21 and is located on the side of the convex ring 23 facing the pull ring 20.
