Embodiment Construction

[0009] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] Depend on Figure 1-3 Provided, the present invention includes a base and a telescopic tube mounted on the base, the telescopic tube is a multi-section circular hollow tube 1 with different diameters, and the previous section is compressed in the next section to form a telescopic structure with adjustable length. Between two adjacent circular hollow tubes, a sliding base 9 is provided on the tube wall at the lower part of the inner circular hollow tube, and above the sliding base 9, a vertically penetrating adjustment is provided on the upper end surface of the outer circular hollow tube. The pressure groove 4, the space between the sliding base 9 and the pressure regulating groove 4 constitute the sliding stroke chamber 10 of the inner circular hollow tube, which is characterized in that the outer side of the sli...

Abstract

The invention relates to a sealing lifting type lifting column which can effectively solve the problems that a telescopic pipe is poor in leakproofness, serious in water leakage and poor in retraction effect. According to the technical scheme, the lifting column comprises a base and a telescopic pipe installed on the base, the telescopic pipe is of a length-adjustable telescopic structure formed by multiple sections of circular hollow pipes with different diameters in the mode that the previous section is compressed in the next section, a slidable seal ring used for sealing is arranged between the outer side of a sliding base of each inner-side circular hollow pipe and the inner wall of the corresponding outer-side circular hollow pipe, and each slidable seal ring comprises a first Y-shaped seal ring body which is located on the upper portion and provided with an upward opening and a second Y-shaped seal ring body which is located on the lower portion and provided with an downward opening. The sealing lifting type lifting column is novel and unique in structure, simple, reasonable, easy to produce, low in cost, good in leakproofness, high in retraction speed, capable of saving energy and water, convenient to use and good in effect and has good social and economic benefits.

Description

technical field [0001] The invention relates to a sprinkling device for irrigation, in particular to a lifting column for a multifunctional irrigation and fertilization system. Background technique [0002] Agriculture is an important basic industry in our country. The traditional method of irrigation and fertilization is manual, which is time-consuming and labor-intensive, and the efficiency is low. Using advanced facilities and technologies, it is the most important thing for our country to shift from "depending on the sky" to large-scale automated production. In the direction of agricultural development, there are many irrigation and fertilization equipments on the market. However, due to their structural problems, the cost of the equipment is high and the functions are few. It is very inconvenient and the effect is unsatisfactory. Therefore, the applicant has applied for a "multifunctional irrigation and fertilization system" with the application number "201320400678.X"....
