Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of irrigation equipment, concretely is a kind of anti-clogging drip irrigation pipe dripper. BACKGROUND

[0002] In drip irrigation pipe, for the embedded drip irrigation pipe dripper, the problem of blockage often occurs, the water inlet of the existing embedded drip irrigation pipe dripper is often in the middle of the surface of the dripper, and the water inlet and the water outlet are on the same surface, although similar labyrinth is used to filter sand and stones in water, the filtering effect is general, and blockage may occur after long-term use, and the existing embedded dripper is found during use that if water bubbles appear in water, the water bubbles will not break when contacting the water inlet, and if the water bubbles cover the water inlet, the water will not enter through the water inlet, thereby affecting the effect of drip irrigation.

[0003] In order to solve the above problems, Chinese patent CN202387601U, an embedded drip irrigation pipe dripper, points out that the water outlet groove is designed in U shape, and the flow is combined with the wave shape to realize the condition of no blockage, this way can indeed prevent the occurrence of blockage to a certain extent, but if the amount of water bubbles is too large, it cannot be guaranteed that the water bubbles will not block the water inlet, and the design of the wave shape and U-shaped water groove is not good for preventing blockage.

[0004] Therefore, in order to improve the anti-clogging effect and prevent the problem of water inlet blockage caused by a large amount of water bubbles, an anti-clogging drip irrigation pipe dripper is proposed. UTILITY MODEL CONTENT

[0006] To achieve the above object, the utility model provides the following technical scheme: A kind of anti-clogging drip irrigation pipe dripper, including drip irrigation pipe, hole is set on the surface of drip irrigation pipe, embedded dripper is embedded in the inside of drip irrigation pipe, embedded dripper includes dripper shell, first protrusion, second protrusion, third protrusion, fourth protrusion, fifth protrusion, sixth protrusion are sequentially arranged on the surface of dripper shell from left to right, third protrusion right side surface is provided with water inlet, fourth protrusion is made of long strip protrusion, recess is formed between adjacent two groups of long strip and the surface of dripper shell, inclined protrusion is arranged on the opposite side of long strip protrusion, long strip protrusion right side surface is provided with water outlet opening, recess is formed between the left side surface of fifth protrusion and the surface of dripper shell, recess corresponds with hole, stop block is arranged on the opposite side of long strip protrusion left end, water inlet is communicated with the inside of dripper shell and the place of corresponding dripper shell inner wall is equipped with built-in protrusion, first opening is set on the outer surface of built-in protrusion at equal intervals, second opening is set on the two sides of built-in protrusion, and interception structure is installed in the right end port of drip irrigation pipe.

[0007] By the above technical scheme, further, the two sides of the built-in protrusion are arranged as semicircular arc, and the second opening is arranged on the arc surface.

[0008] As a preferred technical scheme, the interception structure includes a conical column pipe installed in the right end port of the drip irrigation pipe, and the inner surface of the conical column pipe is provided with a stepped annular protrusion.

[0009] Further, the outer surfaces of the first protrusion, the second protrusion, the third protrusion, the fourth protrusion, the fifth protrusion, and the sixth protrusion form cavities with the inner wall of the drip irrigation pipe.

[0010] As a preferred technical scheme, grooves are arranged on the surface of the long strip protrusion, and the grooves are connected to each other.

[0011] Further, the inclined protrusions on the opposite sides of the two fourth protrusions are staggered, and each inclined protrusion is inclined to the left by 45 degrees.

[0012] As a preferred technical scheme, a first filter pad is arranged on the surface of the dripper shell between the right side surface of the third protrusion and the left side surface of the fourth protrusion, and a second filter pad is arranged on the surface of the dripper shell between the right side surface of the fourth protrusion and the fifth protrusion.

[0013] Further, sealing pads are arranged between the first protrusion and the second protrusion, and between the fifth protrusion and the sixth protrusion.

[0014] As a preferred technical scheme, the height of the stop block is lower than the thickness of the fourth protrusion, and the height of the stop block is half the thickness of the fourth protrusion, and the thickness of the first filter pad is half the height of the stop block.

[0015] Compared with the prior art, this utility model provides an anti-clogging drip irrigation pipe emitter, which has the following beneficial effects:

[0016] 1. This embedded drip irrigation pipe emitter, through its interception structure and inclined protrusions, allows water to first contact the interception structure when it enters the emitter's outer shell. The stepped circular protrusions filter out most of the sand and gravel particles in the water. Then, the water is filtered again by the first filter pad and the inclined protrusions. At this point, the water enters the second filter pad through the outlet opening. The water then flows out through the holes on the surface of the drip irrigation pipe and passes through the built-in protrusion inside the emitter's outer shell. The built-in protrusion has semi-circular arc surfaces on both sides, which allow water bubbles to flow away when they come into contact with it. This design provides an extra layer of protection for the inlet, preventing direct contact between water bubbles and the inlet, thus preventing blockage caused by a large accumulation of bubbles. This three-layer filtration design effectively prevents clogging. Attached Figure Description

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. EMBODIMENT

[0029] Please refer to Figures 1-10 The utility model provides the following technical scheme: an anti-blocking drip irrigation pipe drip head, including drip irrigation pipe 1, the surface of drip irrigation pipe 1 is provided with hole, drip irrigation pipe 1 inside embedded embedded drip head 2, embedded drip head 2 includes drip head shell 201, the surface of drip head shell 201 is sequentially provided with first protrusion 202, second protrusion 203, third protrusion 204, fourth protrusion 206, fifth protrusion 212, sixth protrusion 213 from left to right, the right side surface of third protrusion 204 is provided with water inlet 205, fourth protrusion 206 is formed by long strip protrusion, the adjacent two groups of long strip shape and the surface of drip head shell 201 form recess, the opposite side of long strip protrusion is equipped with inclined protrusion 216, the right side of long strip protrusion is equipped with water outlet opening, the recess is formed between the left end surface of long strip protrusion and the left side of fifth protrusion 212 and the surface of drip head shell 201, and the recess corresponds to the hole, the opposite side of left end of long strip protrusion is equipped with stop block 215, water inlet 205 is communicated with the inside of drip head shell 201 and is equipped with built-in protrusion 207 at the corresponding inner wall of drip head shell 201, the outer surface of built-in protrusion 207 is provided with first opening 208 at equal distance, the two side surfaces of built-in protrusion 207 are provided with second opening 209, and the right end port of drip irrigation pipe 1 is installed with intercepting structure.

[0030] In this embodiment, the specific working principle is: when water enters the dripper shell 201, it first contacts the interception structure, and the first interception of the interception structure preliminarily filters the sand and stones in the water which are easy to cause blockage, then the water passes through the built-in protrusion 207 from the water inlet 205, and the opposite side of the long strip-shaped protrusion is provided with an inclined protrusion 216, and the sand and stones in the water are filtered again through the inclined protrusion 216, at this time the content of sand and stones is very low, then it flows out through the water outlet opening, and then it flows out through the hole opened on the surface of the drip irrigation pipe 1 for drip irrigation. The built-in protrusion 207 can solve the problem of blockage of the water inlet 205 caused by too much gas bubbles in the water, and the interception structure and the inclined protrusion 216 can effectively prevent the blockage problem caused by sand and stones.

[0031] According to the above, in order to prevent bubbles from accumulating on the right side of the built-in protrusion, the two sides of the built-in protrusion 207 are arc-shaped with a semicircle, and the second opening 209 is opened on the arc surface. Through this setting, the flow rate of the water flow can carry away the bubbles, thereby effectively preventing the accumulation of bubbles.

[0032] How the interception structure realizes effective initial interception can be known from Figure 5 As can be seen, the interception structure includes a conical column pipe 3 installed in the right end port of the drip irrigation pipe 1, and the inner surface of the conical column pipe 3 is provided with a stepped ring protrusion 4. Through the attachment Figure 5 As can be seen, the opening diameter decreases from right to left, and the stepped ring protrusion 4 realizes layer-by-layer interception, thereby improving the effect of initial interception.

[0033] Among them, the outer surface of the first protrusion 202, the outer surface of the second protrusion 203, the outer surface of the third protrusion 204, the outer surface of the fourth protrusion 206, the outer surface of the fifth protrusion 212, and the outer surface of the sixth protrusion 213 form a cavity with the inner wall of the drip irrigation pipe 1. The formation of the cavity facilitates the flow of water.

[0034] For the fourth protrusion 206, please refer to Figure 7 As can be seen, the long strip-shaped protrusion surface is provided with a groove, and the groove connects the grooves formed by the adjacent two groups of long strip-shaped protrusions. Through the setting of the two different grooves, the water flowability is realized. Through the setting of the two grooves, the fourth protrusion 206 becomes a separate block structure.

[0035] In order to improve the filtering effect of sand and stones, please refer to Figure 5 As can be seen, the inclined protrusions 216 on the opposite sides of the two groups of fourth protrusions 206 are staggered, and the inclined protrusions 216 are all inclined to the left by 45°. This setting makes the water flow first contact the included angle between the inclined protrusion 216 and the fourth protrusion 206, and then flow into another included angle to realize layer-by-layer filtration. In this way, the sand and stones in the water are reduced to the lowest possible level.

[0036] In order to prevent the problem of water outlet clogging caused by sand and stone more effectively, please refer to the following Figure 5 It can be seen that the surface of the dripper shell 201 between the right side of the third protrusion 204 and the left side of the fourth protrusion 206 is sleeved with the first filter pad 211, and the surface of the dripper shell 201 between the right side of the fourth protrusion 206 and the fifth protrusion 212 is sleeved with the second filter pad 214.

[0037] In order to increase the airtightness of the embedded dripper 2 when set in the drip irrigation pipe 1, the first protrusion 202 and the second protrusion 203 and the fifth protrusion 212 and the sixth protrusion 213 are all sleeved with the sealing pad 210.

[0038] In order to increase the filtering effect of the first filter pad 211 on sand and stone as much as possible, please refer to the following Figure 6 It can be seen that the height of the stop block 215 is lower than the thickness of the fourth protrusion 206, and the height of the stop block 215 is half the thickness of the fourth protrusion 206, and the thickness of the first filter pad 211 is half the height of the stop block 215.

[0039] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
