Abstract
The utility model relates to a central vertical pipe water sealing structure of a circular sprinkler, which comprises a rotating upper bend, a central vertical pipe and a rotating lower bend. The rotating upper bend is fixedly installed at the upper end of the central vertical pipe, and the rotating lower bend is fixedly installed at the lower end of the central vertical pipe. The central vertical pipe water sealing structure of the circular sprinkler is characterized in that an annular protrusion is arranged on the upper end portion of the central vertical pipe, a sealing rubber ring is installed in the annular protrusion, the bottom end of the rotating upper bend is inserted in the central vertical pipe and sealed with the central vertical pipe through the sealing rubber ring. The central vertical pipe water sealing structure of the circular sprinkler has the advantages of being scientific and reasonable in structural design, capable of effectively achieving sealing between the rotating bend and the central vertical pipe, preventing leakage of irrigation water, ensuring safety of equipment in use and prolonging service life of the equipment, convenient to install and low in cost.
Description
Technical field
The utility model belongs to the center pivot sprinkling machine field, particularly a kind of center pivot sprinkling machine center vertical tube sealing structure for water.
Background technique
Center pivot sprinkling machine is a kind of modern agriculture sprinkling irrigation equipment, can realize super large scope, automation sprinkling irrigation, can effectively improve crop yield, reduces cost of labor.Center pivot sprinkling machine is existing at home and abroad at present to be used comparatively widely.Mainly stride body, tire and the electrical control unit etc. of elbow, a plurality of series connection constitute center pivot sprinkling machine down by elbow, rotation in fixing bracket body, center vertical tube, the rotation; Turning gland is rotatably installed in the supporting sleeve at fixing bracket body middle part; The elbow bottom connects the center vertical tube in the rotation; Vertical tube bottom, center connects rotation elbow down, rotation in the elbow upper end through connecting sleeve with stride body and be connected, a plurality of striding passed through the connecting sleeve connection between the body.Irrigation water through pump by rotation down elbow get into the center vertical tube, and go up elbow through rotation and be delivered to and stride body, and spray through striding the shower nozzle that is provided with at interval on the body.Tradition irrigation sprinkler center vertical tube and rotation are gone up and are adopted simple plug-in mounting Placement between the elbow, and there is poor sealing in it, in the sprinkling irrigation process, occurs water leakage phenomenon easily, and the equipment that influences normally uses.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of good airproof performance is provided, and effectively prevents the center pivot sprinkling machine center vertical tube sealing structure for water of seepage.
The utility model solves its technical problem and realizes through following technological scheme:
A kind of center pivot sprinkling machine center vertical tube sealing structure for water; Comprise rotating and go up elbow, center vertical tube and rotation elbow down; Elbow is gone up in center riser upper end fixed installation rotation, and the fixed installation rotation of vertical tube lower end, center is elbow down, and it is characterized in that: the upper end portion of vertical tube is shaped on annular protrusion at the center; In this annular protrusion, O-ring seal is installed, the elbow bottom is inserted in the vertical tube of center also through the sealing cushion rubber and the central vertical seal of tube in the rotation.
And said center riser upper end goes up the elbow fixed installation through cutting ferrule and rotation.
And elbow fixedly mounts vertical tube lower end, described center with rotating down through flange, and seal washer is installed between flange.
And described O-ring seal is three lip seal cushion rubbers.
Advantage of the utility model and beneficial effect are:
This center pivot sprinkling machine center vertical tube sealing structure for water through at the center riser upper end make annular protrusion; And adopt three lip seal cushion rubbers to seal; Hydraulic pressure from the center vertical tube is big more; Three lip seal cushion rubbers are big more to the extruding force that the turning gland outer wall forms, and sealing is good more, can realize zero leakage fully.
2. center vertical tube of this center pivot sprinkling machine and rotation are gone up under elbow and the rotation and all can be formed good sealing between the elbow, guarantee ne-leakage in running.
3. the utility model scientific structure design is reasonable, can effectively realize the effective sealing between turning gland and the center vertical tube, prevents the seepage of irrigation water; The Security that assurance equipment uses; Prolong service life of equipment, also have simultaneously easy for installation, lower-cost advantage.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the enlarged view of the O-ring seal of the utility model;
Fig. 3 is that the A-A of Fig. 1 is to view.
Embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of center pivot sprinkling machine center vertical tube sealing structure for water; Comprise rotating and go up elbow 1, center vertical tube 6 and rotation elbow 8 down; Elbow is gone up in center riser upper end fixed installation rotation; The fixed installation rotation of vertical tube lower end, center is elbow down, and the elbow rotating sleeve is contained in the fixed cover 2 in the rotation, and fixed cover is installed in the center of fixing bracket body (not shown).Its innovation part is: the upper end portion of vertical tube is shaped on annular protrusion 5 at the center; O-ring seal 4 is installed in this annular protrusion; O-ring seal is three lip seal cushion rubbers, and the elbow bottom is inserted in the vertical tube of center also through the sealing cushion rubber and the central vertical seal of tube in the rotation.The center riser upper end goes up the elbow fixed installation through cutting ferrule 3 and rotation.Elbow fixedly mounts vertical tube lower end, center with rotating down through flange 7, and between flange, seal washer 9 is installed.
Claims (4)
1. center pivot sprinkling machine center vertical tube sealing structure for water; Comprise rotating and go up elbow, center vertical tube and rotation elbow down; Elbow is gone up in center riser upper end fixed installation rotation, and the fixed installation rotation of vertical tube lower end, center is elbow down, and it is characterized in that: the upper end portion of vertical tube is shaped on annular protrusion at the center; In this annular protrusion, O-ring seal is installed, the elbow bottom is inserted in the vertical tube of center also through the sealing cushion rubber and the central vertical seal of tube in the rotation.
