Description

TECHNICAL FIELD

[0001] The present application relates to the field of farmland water conservancy irrigation, in particular to a farmland water conservancy diversion system. BACKGROUND

[0002] The farmland water conservancy irrigation system is an important part of modern agricultural production, and with the advancement of agricultural modernization, how to efficiently and uniformly distribute water resources has become a research focus. The existing farmland water conservancy irrigation system mainly includes traditional sprinkling irrigation, drip irrigation and sprinkling irrigation. Different agricultural products adapt to different irrigation methods, and sprinkling irrigation mainly has the characteristics of low working pressure, uniform and moderate water spraying, no influence on vegetable root system, can increase soil moisture at regular intervals, and can improve air humidity. Compared with traditional sprinkling irrigation, sprinkling irrigation has high water use efficiency, can adjust the field microclimate, and will not cause uneven watering compared with drip irrigation. Therefore, sprinkling irrigation is widely used in vegetable, flower, orchard and medicinal material planting places.

[0003] In related technologies, sprinkling irrigation mainly includes a spray head, a water supply pipe, a water pump and a water supply tank. The water supply tank is in communication with the spray head through the water supply pipe, and the water pump is arranged on the water supply pipe. When the water valve of the water supply tank is opened, the water flow flows into the spray head in the form of mist after flowing through the water supply pipe, thereby providing water source for the growth demand of plants. Sprinkling irrigation can not only provide water for the growth of plant roots, but also adjust the humidity of the plant growth environment.

[0004] For the above-mentioned related technologies, most of the sprinkling irrigation heads are upward water spraying heads, and the water mist sprayed out will spread in the plant growth environment. Some melon and fruit plants adapt to a relatively uniform and moderate irrigation method in the growth process, but the leaves of some melon and fruit plants do not adapt to being wetted frequently. Due to the structural characteristics of sprinkling irrigation, the water mist sprayed out from the spray head spreads upward and wets the leaves of melon and fruit plants, and long-term wetting of the leaves of such plants can easily cause white powdery mildew of the plants, which will adversely affect the growth of the plants. CONTENT OF THE INVENTION

[0005] In order to solve the problem that the roots and leaves of some plants adapt to a relatively moderate sprinkling irrigation, but the leaves of some other plants do not adapt to being wetted frequently, the present application provides a farmland water conservancy diversion system, which has the effect of controlling the direction of sprinkling irrigation water mist during sprinkling irrigation.

[0006] The farmland water conservancy diversion system provided by the present application adopts the following technical scheme:

[0007] The utility model provides an agricultural water conservancy diversion system, comprising a water mist diversion device, a height adjusting device arranged below the water mist diversion device, a water supply pipe communicated with the water mist diversion device, a water pump arranged on the water supply pipe and a water supply tank communicated with the water supply pipe, the water mist diversion device comprises a spray head, the spray head comprises a first spray part spraying water upward and a second spray part spraying water downward below the first spray part, the first spray part is communicated with the second spray part, and the water mist diversion device further comprises a diversion mechanism arranged between the first spray part and the second spray part and used for controlling the on-off of water flow in the first spray part.

[0008] By adopting the above technical scheme, the diversion mechanism arranged between the first spray part and the second spray part controls the on-off of water flow in the first spray part, when water provided by the water supply pipe flows into the second spray part and the first spray part, the first spray part sprays water upward and the second spray part sprays water downward, thus meeting the irrigation requirement of plants whose leaves and roots need to be watered; under the action of the diversion mechanism, when water provided by the water supply pipe only flows into the second spray part, the second spray part sprays water downward, thus meeting the irrigation requirement of plants whose leaves are not suitable to be wetted.

[0009] Optionally, the diversion mechanism comprises a diversion plate arranged in the spray head and a rotating shaft arranged on both sides of the diversion plate, the diversion plate is fixedly connected with the rotating shaft, the diversion mechanism further comprises a rotating handle fixedly connected with one end of the rotating shaft and a locking assembly locking the rotating handle, and the rotating handle is arranged outside the spray head.

[0010] By adopting the above technical scheme, the rotating handle is rotated to rotate the diversion plate around the rotating shaft in the spray head, and the locking assembly locks the rotating handle. The diversion plate is arranged in the spray head to realize the on-off of water flow between the first spray part and the second spray part, the rotating handle is arranged outside the spray head, and the user can control the rotation of the diversion plate through the rotating handle. When the rotating handle is rotated to the position where the diversion plate can realize the on-off of water flow between the first spray part and the second spray part, the locking assembly is locked, so that when water provided by the water supply pipe flows into the spray head, the diversion plate can still realize the on-off of water flow between the first spray part and the second spray part under the impact of water flow.

[0011] Optionally, a thread is formed on the outer circumferential surface of the part of the rotating shaft located outside the spray head, and the locking assembly comprises a locking ring matched with the thread.

[0012] By adopting the technical scheme, the thread formed on the rotating shaft is used in cooperation with the locking ring, when the rotating handle is rotated to the position required to be locked, the locking ring is rotated to the side close to the spray head and abuts against the outer side wall of the spray head. With the continuous rotation of the locking ring, the pressure between the locking ring and the spray head continuously increases, so the friction between the locking ring and the outer side wall of the spray head continuously increases, and finally the relative locking between the locking ring and the spray head is realized. Meanwhile, since the locking ring is threadedly connected with the rotating shaft, the locking of the rotating shaft is realized under the locking of the locking ring.

[0013] Optionally, the shunt mechanism further comprises a positioning assembly, the positioning assembly comprising a positioning block arranged on the side wall of the shunt plate and a positioning groove formed in the inner side wall of the spray head and used in cooperation with the positioning block.

[0014] By adopting the technical scheme, when the positioning block is embedded in the positioning groove, the shunt plate cuts off the water supply in the first spray part. Since the positioning block is embedded in the positioning groove, the user needs to exert more force on the rotating handle to rotate it. By rotating the rotating handle to embed the positioning block in the positioning groove, the user can conveniently position the rotating position of the shunt plate.

[0015] Optionally, the water mist shunt device further comprises a guide mechanism arranged on the spray head, the guide mechanism comprising a guide plate for downward guiding the water mist sprayed by the second spray part and a fixing ring for sleeving the guide plate on the spray head, the guide plate being integrally formed with the fixing ring.

[0016] By adopting the technical scheme, the fixing ring in the guide mechanism facilitates the user to arrange the guide plate on the spray head. When the second spray part sprays water mist downward, a small amount of water mist will still spread upward to the leaves of the plant, the guide plate in the guide mechanism blocks the small amount of water mist spreading upward, thereby ensuring the growth requirement of the plant whose leaves are not suitable to be wetted.

[0017] Optionally, the outer side wall of the spray head is formed with a fixing groove for embedding and fixing the fixing ring.

[0018] By adopting the technical scheme, the fixing groove is formed in the outer side wall of the spray head, and the fixing ring in the guide mechanism is embedded in the fixing groove, thereby ensuring the fixing between the guide mechanism and the spray head.

[0019] Optionally, the included angle between the guide plate and the fixing ring is 10°-40°.

[0020] By adopting the technical scheme, when the included angle between the guide plate and the fixing ring is 10°-40°, the guide plate has a large range of blocking the water mist sprayed by the second spraying part, and the water mist sprayed by the second spraying part has a small range of downward diffusion, which is suitable for plants whose roots do not need large-scale watering.

[0021] Optionally, the included angle between the guide plate and the fixing ring is 60°-90°.

[0022] By adopting the technical scheme, when the included angle between the guide plate and the fixing ring is 60°-90°, the guide plate has a small range of blocking the water mist sprayed by the second spraying part, and the water mist sprayed by the second spraying part has a large range of downward diffusion, which is suitable for plants whose roots need large-scale watering.

[0023] Optionally, the height adjusting device comprises an electric telescopic rod having one end fixedly connected to the bottom of the spraying head and a base fixedly connected to the other end of the electric telescopic rod away from the spraying head.

[0024] By adopting the technical scheme, since the growth heights of different plants are different, the height adjusting device adjusts the height of the spraying head, so as to adjust the height of the water mist sprayed by the spraying head, and meet the watering needs of plants of different heights.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. The spraying head of the water mist shunting device is divided into a first spraying part and a second spraying part, and the shunting mechanism between the first spraying part and the second spraying part controls the on-off of the water flow in the first spraying part, realizes the downward spraying mode of the second spraying part, and realizes the upward spraying mode of the first spraying part and the downward spraying mode of the second spraying part at the same time, that is, meets the irrigation needs of plants whose leaves and roots need watering and meets the irrigation needs of plants whose leaves are not suitable for being wetted.

[0027] 2. When the downward spraying mode of the second spraying part is started, the guide mechanism arranged on the spraying head blocks a small amount of upwardly diffused water mist, realizes the irrigation needs of plants whose leaves are not suitable for being wetted, and ensures the healthy growth of the plants.

DETAILED DESCRIPTION

[0035] The following will be described in detail in combination with the accompanying Figures 1-6 The present application is further described in detail.

[0036] Referring to FIG. 1 and Figure 2 The embodiment of the present application discloses a farmland water conservancy shunting system, which comprises a water mist shunting device 1, a height adjusting device 2 arranged below the water mist shunting device 1, a water supply pipe 3 in communication with the water mist shunting device 1 and a water supply tank 5 in communication with the water supply pipe 3, and a water pump 4 installed on one side of the water supply pipe 3 close to the water supply tank 5 and used for supplying water to the water mist shunting device 1.

[0037] The water mist shunting device 1 comprises a spray head 11, the spray head 11 comprises a first spray part 111 for upward spraying and a second spray part 112 for downward spraying, the first spray part 111 is located above the second spray part 112 and the first spray part 111 is in communication with the second spray part 112. A plurality of upward spraying spray openings are formed in the first spray part 111, a plurality of downward spraying spray openings are formed in the second spray part 112, a water inlet is formed in the bottom of the second spray part 112 and connected with the water supply pipe 3, and the second spray part 112 is in communication with the water supply pipe 3 through the water inlet. The water mist shunting device 1 further comprises a shunting mechanism 12 arranged between the first spray part 111 and the second spray part 112, and the shunting mechanism 12 is used for controlling the on-off of water flow in the first spray part 111.

[0038] The height adjusting device 2 comprises an electric telescopic rod 21 and a base 22, one end of the electric telescopic rod 21 is fixedly connected with the bottom of the spray head 11, and the other end of the electric telescopic rod 21 away from the spray head 11 is fixedly connected with the base 22. The height of the spray head 11 is adjusted by adjusting the electric telescopic rod 21, so as to meet the watering needs of plants with different heights.

[0039] With reference to Figure 2 and Figure 3 , the shunt mechanism 12 comprises a shunt plate 121 arranged in the spray head 11 and a rotating shaft 122 arranged on both sides of the shunt plate 121, and the shunt plate 121 is fixedly connected with the rotating shaft 122. The shape of the shunt plate 121 matches the shape of the cross section of the inside of the spray head 11, so that the rotation of the shunt plate 121 controls the on-off of the water flow in the first spray part 111. The inside wall of the spray head 11 is provided with a first rotating hole and a second rotating hole, the second rotating hole is a through hole, one end of the rotating shaft 122 is embedded in the first rotating hole, and the other end of the rotating shaft 122 away from the first rotating hole extends through the second rotating hole to the outside of the spray head 11.

[0040] When the shunt plate 121 is rotated to the horizontal direction, the side wall of the shunt plate 121 closely abuts against the inside wall of the spray head 11, so as to block the water flow into the first spray part 111; when the shunt plate 121 is rotated to the vertical direction, the side wall of the shunt plate 121 is separated from the inside wall of the spray head 11, so that the water flow in the first spray part 111 and the second spray part 112 is communicated.

[0041] With reference to Figure 3 and Figure 4 , the shunt mechanism 12 further comprises a positioning assembly 125 for positioning the rotating position of the shunt plate 121, and the positioning assembly 125 comprises a positioning block 1251 and a positioning groove 1252, and the positioning block 1251 is fixedly arranged on the side wall of the shunt plate 121. In the embodiment, the material of the positioning block 1251 is a rubber positioning block 1251, and it should be noted that the positioning block 1251 can also be other elastic materials, and is not limited to rubber. The positioning groove 1252 is arranged on the inside wall of the spray head 11 and is located at the position corresponding to the positioning block 1251 when the shunt plate 121 is rotated to the horizontal direction, and the size of the positioning groove 1252 matches the size of the positioning block 1251.

[0042] When the shunt plate 121 is rotated to the horizontal direction, the positioning block 1251 on the shunt plate 121 is embedded in the positioning groove 1252, at this time, in order to rotate the shunt plate 121 by rotating the handle 123, the user needs to exert greater force to rotate the handle 123 to rotate the shunt plate 121, which facilitates the user to rotate the handle 123 to position the rotating position of the shunt plate 121.

[0043] With reference to Figure 3 and Figure 5The shunt mechanism 12 further comprises a rotating handle 123 fixedly connected with one end of the rotating shaft 122 and a locking assembly 124 locking the rotating handle 123, and the rotating handle 123 is arranged outside the spray head 11. The part of the rotating shaft 122 outside the spray head 11 is provided with a thread 1241 on the outer circumferential surface, and the locking assembly 124 comprises a locking ring 1242 matched with the thread 1241.

[0044] When the rotating handle 123 is rotated to the position required to be locked, the locking ring 1242 is rotated to the side close to the spray head 11 and abuts against the outer side wall of the spray head 11. With the continuous rotation of the locking ring 1242 to the side close to the spray head 11, the pressure between the locking ring 1242 and the spray head 11 continuously increases, so that the friction between the locking ring 1242 and the outer side wall of the spray head 11 continuously increases, and finally the relative locking between the locking ring 1242 and the spray head 11 is realized. At the same time, since the locking ring 1242 is connected with the thread 1241 of the rotating shaft 122, the locking of the rotating shaft 122 is realized under the locking of the locking ring 1242, the rotating handle 123 and the rotating shaft 122 are fixedly connected, and the rotating handle 123 is also locked.

[0045] Referring to Figure 1 and Figure 6 , the water mist shunt device 1 further comprises a guide mechanism 13 arranged on the spray head 11, the guide mechanism 13 comprises a guide plate 131 guiding the water mist sprayed by the second spray part 112 downward and a fixing ring 132 sleeving the guide plate 131 on the spray head 11, and the guide plate 131 and the fixing ring 132 are integrally formed. In the embodiment, the integrally formed guide plate 131 and fixing ring 132 are made of PVC material, and it should be noted that the guide plate 131 and the fixing ring 132 can also be made of other materials with high hardness and elasticity, and are not limited to PVC material. The outer side wall of the spray head 11 is provided with a fixing groove 133 for embedding and fixing the fixing ring 132, and the size of the fixing groove 133 matches the size of the fixing ring 132.

[0046] The included angle between the guide plate 131 and the fixing ring 132 is 10°-40°, or 60°-90°. When the included angle between the guide plate 131 and the fixing ring 132 is 10°-40°, the range of the water mist sprayed by the second spray part 112 diffusing downward is small; when the included angle between the guide plate 131 and the fixing ring 132 is 60°-90°, the range of the water mist sprayed by the second spray part 112 diffusing downward is large. In the embodiment, the included angle between the guide plate 131 and the fixing ring 132 is 70°. When it is required to spray the plants which are not suitable to be wetted by the blades, the user opens the second spray part 112, and the water mist sprayed by the second spray part 112 diffuses downward under the guiding action of the guide plate 131, so that a small amount of diffused water mist will not wet the leaves of the plants.

[0047] The implementation principle of the farmland water conservancy diversion system is that the water in the water tank flows into the water supply pipe 3, and under the action of the water pump 4, the water flows into the second spraying part 112 from the water inlet. When it is needed to spray irrigation on the plants whose leaves are not suitable to be wetted, the user first rotates the rotating handle 123, rotates the diversion plate 121 to the horizontal direction through the positioning assembly 125, and then rotates the locking ring 1242 to abut against the outer side wall of the spraying head 11, so that the rotating handle 123 is locked. When it is needed to spray irrigation on the plants whose leaves and roots need to be watered, the user rotates the rotating handle 123, rotates the diversion plate 121 to the vertical direction through the positioning assembly 125, and then rotates the locking ring 1242 to abut against the outer side wall of the spraying head 11, so that the rotating handle 123 is locked. The above two spraying modes meet the irrigation needs of the plants whose leaves and roots need to be watered, and meet the irrigation needs of the plants whose leaves are not suitable to be wetted, so that different types of plants can grow healthily under the corresponding spraying mode.

[0048] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
