A patch piece of a water hose for trickle irrigation comprises a patch body and a nut. The head portion of the patch body is in a shape of a cone with a small front portion and a big rear portion, the tail portion of the patch body forms a screw rod, the external threads of the screw rod are matched with the internal threads of the nut, the diameter of the screw rod is smaller than that of the rear end of the head portion of the patch body, a circular rear end face is formed at the rear end of the head portion of the patch body, and the circular rear end face is perpendicular to the central axis of the screw rod. A splined hole is formed in the central portion of the rear end of the screw rod, the opening of the splined hole is formed in the end face of the rear end of the screw rod, the central axis of the splined hole is overlapped with the central axis of the screw rod, and the front end of the splined hole is closed to form a blind hole. The patch piece of the water hose for the trickle irrigation is suitable for a thin-wall soft water hose, is good in seal effect and capable of being recycled.
Description
Technical field
The utility model belongs to the technical field of agricultural drop irrigation equipment, is specifically related to a kind of patch spare of drip-irrigation water band.
Background technique
The drip-irrigation water band is widely used in the drip irrigation system of agricultural planting as arm, connects the hollow billet drip irrigation zone.The drip-irrigation water band mainly contains PVC plastic coated water band band, robber cement band and modified poly ethylene water band.Wherein, PVC plastic coated water band band, robber cement band wall thickness all more than 1mm, therefore are called for short by " heavy wall soft water band "; Modified poly ethylene water band wall thickness all below 1mm, therefore is called for short by " thin-walled soft water band ".When drip irrigation system is installed in the plantation place, must tee pipe fitting or two siphunculus spare be installed at the arm place of system, in order to water is drawn from tee pipe fitting or two siphunculus spare, enter the hollow billet drip irrigation zone.Every installation tee pipe fitting or a two siphunculus spare will form a mounting hole at drip-irrigation water band tube wall, and the spacing between mounting hole must be corresponding with the plantation spacing of crops.So, whenever plantation place replacing crops, when the plantation spacing changes, just must readjust the spacing of tee pipe fitting or two siphunculus spare, the mounting hole that formed in the past on the drip-irrigation water band just must adopt patch spare to carry out shutoff, otherwise this drip-irrigation water band just can't continue to use.
The structure of tradition drip-irrigation water band patch spare and usage mode are as shown in Figure 1.the section of this patch spare is I shape, fill in by force the mounting hole of drip-irrigation water band 4 during use, but above-mentioned traditional patch spare has the following disadvantages: 1, mainly be applicable to heavy wall soft water band, and be not suitable for thin-walled soft water band, this be because, heavy wall soft water band elasticity is better and pipe thickness is large, it is installed the edge, aperture and can make progress from the footpath round member in the middle of patch spare is tightened and realize to seal, otherwise, PE water band elasticity is relatively poor and pipe thickness is little, can't make progress from the footpath round member of patch spare is tightened, therefore sealing effect is very poor, when if consequently existing thin-walled soft water band runs into the situation of change crops, just must change, 2, after the water band cancelled, traditional patch spare was difficult to extract, and can't recycle.
The model utility content
The purpose of this utility model is to overcome above-mentioned shortcoming and provides and a kind of drip-irrigation water band patch spare, and it is adapted to thin-walled soft water band, good sealing effect, and can recycle.
Its purpose can realize by following scheme: a kind of patch spare of drip-irrigation water band, comprise patch body and nut, the head of patch body is pre-small post-large taper, the afterbody of patch body forms screw rod, the outside thread of screw rod and the internal thread of nut coupling, the diameter of screw rod forms the ear end face of ring less than the diameter of patch body head rear end in the rear end of patch body head, the ear end face of this ring is perpendicular to the central axis of screw rod; Center portion at spiro rod rear end also is formed with splined hole, and the aperture of splined hole is positioned at the end face of spiro rod rear end, and the central axis of splined hole and the central axis of screw rod are overlapping, the front end of splined hole sealing and form blind hole.
Also be formed with the thread groove of one depression at the conical surface of patch body head.Like this, the head of being convenient to the patch body can pierce by the mode that is screwed into the mounting hole of water band.
The patch spare of this drip-irrigation water band is the supporting operating lever that the T font is arranged also, the end of operating lever with the spline of screw rod splined hole coupling.
Described splined hole is hex hole, and the end cross section of operating lever is hexagon.
The utlity model has following advantage and effect:
When 1, the utility model uses, patch body head can be screwed into or fill in water band mounting hole inner, the screw rod of patch body afterbody exposes in water band mounting hole outside, then nut is screwed upper screw rod (can utilize the splined hole of spiro rod rear end that screw rod is fixed when being screwed), the ring ear end face of patch body head and the end face of nut are clamped position, mounting hole edge, so just realize the mounting hole shutoff.
2, owing to can utilizing manpower to tighten, therefore can to greatest extent position, mounting hole edge be clamped, sealing effect is than traditional patch good (traditional patch can only utilize small radial elastic power that patch spare is tightened)
3, after the water band cancels, nut can be twisted away from screw rod, and patch body head is back-outed or extracted out from mounting hole, patch spare recoverable.
4, patch spare of the present utility model is both applicable to thin-walled soft water band, certainly also applicable to heavy wall soft water band.

Embodiment
Fig. 2, Fig. 3, shown in Figure 4, the patch spare of this drip-irrigation water band comprises patch body 1 and nut 2, the head 11 of patch body is pre-small post-large taper, the afterbody of patch body forms screw rod 12, the internal thread coupling of the outside thread of screw rod 12 and nut 2, the diameter of screw rod 12 forms the ear end face 13 of ring less than the diameter of patch body head 11 rear ends in the rear end of patch body head 11, the ear end face 13 of this ring is perpendicular to the central axis of screw rod; Center portion at spiro rod rear end also is formed with hexagon splined hole 14, and the aperture of splined hole 14 is positioned at the end face of spiro rod rear end, and the central axis of the central axis of splined hole 14 and screw rod 12 is overlapping, the front end of splined hole 14 sealing and form blind hole.Also be formed with the thread groove 15 of one depression at the conical surface of patch body head.
