Description

Technical Field

[0001] The invention relates to the technical field of crop irrigation equipment, and in particular to an irrigation machine for crop planting. Background Art

[0002] Agricultural irrigation mainly refers to irrigation operations in agricultural farming areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. As a type of surface irrigation, underground crop irrigation machines are equipment used for regular watering of crops. Under normal circumstances, they are hidden between 40 and 60 centimeters underground and do not affect the tillage of the land by surface farming equipment. Only when in use will they use water pressure to drill out of the ground and irrigate the farmland.

[0003] The existing underground crop irrigation machines have the following problems in actual use. On the one hand, since the irrigation nozzles are buried underground for a long time, when they are not used for a long time or in fields with hard soil, the irrigation nozzles will not be able to pop out from the soil layer during operation, thus affecting the normal operation of the equipment. On the other hand, since the irrigation nozzles need to be hidden below the surface when not in use, it will result in the inability to install a larger adjustment component on the top of the irrigation nozzles, resulting in the traditional underground irrigation nozzles being able to perform only a single water spraying operation each time they are operated. The functionality needs to be improved and has limitations in actual use. Summary of the invention

[0004] The invention discloses an irrigation machine for crop planting, aiming to solve the technical problems that the existing underground crop irrigation machine cannot be ejected from below the ground surface and the water spraying angle cannot be adjusted when not used for a long time in actual use, which is limited.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An irrigation machine for planting crops, comprising a main water pipe, a telescopic mechanism for spraying high-pressure water flow is arranged on the top of the main water pipe, the telescopic mechanism comprises a water branch pipe sleeved and fixed on the top of the main water pipe, a water spray pipe is slidably installed inside the water branch pipe, and the water branch pipe, the water spray pipe and the main water pipe are connected to each other;

[0007] The top of the telescopic mechanism is provided with an adjusting mechanism for controlling the flow direction of water, and the adjusting mechanism comprises a sealing shell sleeved and fixed on the top of the water spray pipe, a main shaft is slidably mounted in the interior of the sealing shell along the vertical direction, and a cross spring piece is slidably sleeved on the bottom of the main shaft;

[0008] A soil-breaking mechanism for breaking through the soil layer is arranged on the top of the telescopic mechanism;

[0009] The telescopic mechanism controls the water pressure to drive the regulating mechanism to operate and regulate the direction of the water flow. At the same time, when the telescopic mechanism is buried in the ground, the ground-breaking mechanism is lifted to break the ground and assist the telescopic mechanism to be pushed out of the ground.

[0010] By providing a telescopic mechanism that is driven to rotate by water flow on the basis of a traditional underground irrigation machine, the rotation of the telescopic mechanism drives the adjusting mechanism to rotate synchronously, and the change in water pressure drives the adjusting mechanism to rotate while adaptively changing the direction of water spraying, so that different crops can be irrigated according to needs, thereby improving the functionality of traditional underground irrigation machines. At the same time, when the irrigation machine is located below the ground surface, an additional soil-breaking mechanism can break the soil layer on the top of the irrigation machine through water pressure, thereby assisting the entire device to extend from the soil, thereby improving the completeness and functionality of the equipment operation.

[0011] In a preferred solution, the telescopic mechanism further comprises spiral blades fixedly mounted on the bottom of the water distribution pipe, the spiral blades are distributed inside the main water pipe, and a plurality of evenly distributed water inlets are opened through the bottom of the water distribution pipe.

[0012] By setting up a water distribution pipe structure with spiral blades, the pressure generated by water flowing through the main water pipe is used to drive the water distribution pipe to rotate. At the same time, water can enter the water distribution pipe and the water spray pipe through an additional water inlet, thereby driving the water spray pipe to rotate and spray water outward, thereby ensuring the complete operation of the device.

[0013] In a preferred embodiment, the regulating mechanism further comprises a plurality of evenly distributed cover plates slidably mounted on the inner wall of the sealing shell, the end of the cross spring sheet is pressed and contacted with the side of the cover plate, the outer surface of the sealing shell is penetrated by a plurality of groups of evenly distributed water outlet holes, and the cover plates and the water outlet holes are symmetrically distributed in the horizontal direction.

[0014] By setting a cross spring piece structure with a sealing shell, the water pressure from the top of the water spray pipe is used to control the deformation of the cross spring piece. When the water pressure is normal, the sprayed water flow can be sprayed out from the top of the sealing shell through the main shaft. When the water pressure increases, the sprayed water flow will impact the cross spring piece, causing the cross spring piece to deform and pull the cover plate to move vertically, thereby exposing the water outlet hole on the outer surface of the sealing shell and changing the direction of the water sprayed from the water spray pipe to allow the water to flow out through the water outlet hole, resulting in two working modes of the device, one is to spray water outward from the top of the sealing shell, and the other is to spray water outward from the side of the sealing shell, thereby greatly improving the functionality of the device.

[0015] In a preferred embodiment, the earth-breaking mechanism includes a fixing ring which is sleeved and fixed on the outside of the main shaft, a second spring is fixedly connected between the fixing ring and the inner surface of the sealing shell, the second spring is sleeved on the outside of the main shaft, a cutter head is fixedly connected to the top of the main shaft, and the cutter head is slidably installed inside the sealing shell and passes through the top of the sealing shell.

[0016] By providing a cutter head fixedly mounted on the top of the main shaft, the increase in water pressure is used to push the cross spring piece to further drive the main shaft and the cutter head to move vertically, so as to be pushed out from the top of the sealing shell, and the water distribution pipe drives the water spray pipe to rotate synchronously, stirring the soil layer wrapped around the outside of the sealing shell, thereby helping the water spray pipe to be pushed out of the soil and operate normally, thereby improving the completeness and functionality of the operation of the device.

[0017] In a preferred embodiment, a plurality of groups of snap-fitting parts are symmetrically fixed on the inner surface of the sealing shell, each of the cover plates is slidably installed inside the snap-fitting parts, a first elastic member is fixed to the bottom of each of the snap-fitting parts, and the top of the first elastic member is pressed and contacted with the bottom of the cover plate.

[0018] The cover plate is restricted by providing a clamping portion with a first elastic member, ensuring that the cover plate can slide along the inside of the clamping portion when squeezed, and at the same time the first elastic member can push the cover plate that has lost the restriction to reset, thereby ensuring the stability of the cover plate and the integrity of the cyclic operation of the device.

[0019] As can be seen from the above, the crop planting irrigation machine provided by the present invention has the following improvements and advantages compared with the prior art:

[0020] First, on the basis of the traditional underground irrigation machine, a sealing shell with a cross spring structure is arranged on the top of the water spray pipe, and the water pressure from the top of the water spray pipe is used to control the deformation of the cross spring. When the water pressure is normal, the sprayed water flow can be sprayed out from the top of the sealing shell through the main shaft. When the water pressure increases, the sprayed water flow will impact the cross spring, causing the cross spring to deform and pull the cover plate to move vertically, thereby exposing the water outlet holes on the outer surface of the sealing shell, and changing the direction of the water flow sprayed from the water spray pipe, so that the water flow is dispersed and sprayed out through the water outlet holes, resulting in two working modes of the device, one is to spray a water column outward from the top of the sealing shell, and the other is to spray water mist outward from the side of the sealing shell, thereby greatly improving the functionality of the device.

[0021] Secondly, on the basis of the traditional underground irrigation machine, spiral blades are additionally installed at the bottom of the water distribution pipe, and the spiral blades are rotated by the impact of water flow. At the same time, when the device is located below the ground surface, the continuously pressurized water flow can push the cross spring pieces to further drive the main shaft and the cutter head to move vertically, thereby ejecting from the top of the sealing shell, and cooperating with the water distribution pipe to drive the water spray pipe to rotate synchronously, stirring the soil layer wrapped around the outside of the sealing shell, thereby helping the water spray pipe to be ejected from the soil and operate normally, further improving the integrity and functionality of the operation of the device.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The invention discloses an irrigation machine for planting crops, which is mainly used for regular irrigation of crops.

[0033] Reference Figures 1 to 8 A crop planting irrigation machine comprises a main water pipe 1, a telescopic mechanism 2 for spraying high-pressure water flow is arranged on the top of the main water pipe 1, the telescopic mechanism 2 comprises a water distribution pipe 201 sleeved and fixed on the top of the main water pipe 1, a water spray pipe 202 is slidably installed inside the water distribution pipe 201, and the water distribution pipe 201, the water spray pipe 202 and the inside of the main water pipe 1 are mutually connected; a regulating mechanism 3 for controlling the flow direction of water flow is arranged on the top of the telescopic mechanism 2, the regulating mechanism 3 comprises a sealing shell 301 sleeved and fixed on the top of the water spray pipe 202, a main shaft 302 is slidably installed inside the sealing shell 301 along the vertical direction, and a cross spring piece 303 is slidably sleeved on the bottom of the main shaft 302; a ground-breaking mechanism 4 for breaking through the soil layer is arranged on the top of the telescopic mechanism 2; the water pressure is controlled by the telescopic mechanism 2 to drive the regulating mechanism 3 to operate and regulate the flow direction of the water flow, and when the telescopic mechanism 2 is buried in the ground, the ground-breaking mechanism 4 is lifted to break the ground and assist the telescopic mechanism 2 to be supported out of the ground.

[0034] In this embodiment: Under normal conditions, the telescopic mechanism 2 is hidden at a depth of forty to sixty centimeters below the ground surface. When water flows into the main water pipe 1, the high-pressure water flow will enter the interior of the telescopic mechanism 2 through the main water pipe 1, and use the water pressure to push the telescopic mechanism 2, causing the telescopic mechanism 2 to rotate while extending and being pushed out of the soil, and spraying water onto the farmland through the top of the telescopic mechanism 2. When the water pressure inside the main water pipe 1 increases, the regulating mechanism 3 starts to operate under the influence of the water pressure, and transforms the water column sprayed from the top of the telescopic mechanism 2 into a water mist sprayed from the side of the telescopic mechanism 2, thereby causing the device to have two working modes; when water flows into the main water pipe 1 to push the telescopic mechanism 2, but the telescopic mechanism 2 cannot be pushed out of the soil, the water pressure inside the main water pipe 1 continues to increase, and the water pressure will drive the earth-breaking mechanism 4 to operate, causing the earth-breaking mechanism 4 to rotate along with the telescopic mechanism 2, thereby assisting the telescopic mechanism 2 to be pushed out of the soil.

[0035] In the above scheme, in order to improve the working efficiency of the earth-breaking mechanism 4, the specific operations are as follows.

[0036] Reference Figures 1 to 6In a preferred embodiment, the telescopic mechanism 2 also includes a spiral blade 203 fixedly installed at the bottom of the water distribution pipe 201, the spiral blade 203 is distributed inside the main water pipe 1, and a plurality of evenly distributed water inlets 204 are opened through the bottom of the water distribution pipe 201.

[0037] In this embodiment, when water flows into the main water pipe 1, the high-pressure water will enter the inside of the water distribution pipe 201 through the main water pipe 1, and use the water pressure to push the spiral blade 203, so that the spiral blade 203 drives the water distribution pipe 201 and the water spray pipe 202 to rotate. At the same time, the water flow inside the main water pipe 1 will push the water spray pipe 202 to move vertically along the inside of the water distribution pipe 201, so as to be pushed out from the soil and spray water to the farmland through the top of the water spray pipe 202. The outer surface of the water spray pipe 202 is provided with a protrusion 206, and the inner surface of the water distribution pipe 201 is provided with a protrusion 206. A sliding groove 207 is provided, and a protrusion 206 is slidably engaged in the inside of the sliding groove 207. The protrusion 206 cooperates with the restriction of the sliding groove 207 to ensure that when the water distribution pipe 201 rotates, the water spray pipe 202 can be driven to rotate together, and a first spring 205 is fixedly connected between the water distribution pipe 201 and the water spray pipe 202. The first spring 205 is distributed inside the water distribution pipe 201. When the water supply inside the main water pipe 1 stops, the water spray pipe 202 that loses the pressure will be pulled by the first spring 205, thereby returning to the inside of the water distribution pipe 201.

[0038] In the above scheme, in order to improve the functionality of the traditional irrigation machine, the specific operation is as follows.

[0039] Reference Figures 1 to 3 , Figures 5 to 8 In a preferred embodiment, the regulating mechanism 3 also includes a plurality of evenly distributed cover plates 304 slidably mounted on the inner wall of the sealing shell 301, the end of the cross spring piece 303 is pressed and contacted with the side of the cover plate 304, and a plurality of groups of evenly distributed water outlet holes 305 are penetrated through the outer surface of the sealing shell 301, and the cover plates 304 and the water outlet holes 305 are symmetrically distributed in the horizontal direction.

[0040] In this embodiment: when water flows into the main water pipe 1, the high-pressure water flow will enter the interior of the water spray pipe 202 through the main water pipe 1 and spray water to the farmland through the top of the water spray pipe 202. At this time, the water flow sprayed from the top of the water spray pipe 202 will be sprayed out through the hollow main shaft 302. When the user controls the water pressure inside the main water pipe 1 to increase, the water flow sprayed from the top of the water spray pipe 202 will expand and spray to the lower surface of the cross spring piece 303. At the same time, the strong water pressure will push the cross spring piece 303, causing the middle part of the cross spring piece 303 to be pushed upward. At the same time, the end of the cross spring piece 303 will press down the cover plate 304, causing all the cover plates 304 to move downward, The water outlet holes 305 are exposed, and the water flow sprayed from the top of the water spray pipe 202 will move along the surface of the deformed cross spring piece 303 and be differentiated and sprayed from several water outlet holes 305; wherein, several groups of clamping parts 306 are symmetrically fixed on the inner surface of the sealing shell 301, and each cover plate 304 is slidably installed inside the clamping part 306, and a first elastic member 307 is fixed to the bottom of each clamping part 306, and the top of the first elastic member 307 is pressed and contacted with the bottom of the cover plate 304. When the cover plate 304 is squeezed, it will slide along the inside of the clamping part 306. When the cover plate 304 loses the squeeze, it will be pushed by the first elastic member 307, thereby resetting and moving to block the water outlet holes 305.

[0041] Further, it is supplemented that: a pressing portion 5 is provided at the end of the cross spring piece 303 , and the pressing portion 5 is pressed and contacted with the side surface of the cover plate 304 .

[0042] In the above scheme, considering that in order to further assist the water spray pipe 202 to move vertically and break out from under the ground, the specific operations are as follows.

[0043] Reference Figures 5 to 8 In a preferred embodiment, the earth-breaking mechanism 4 includes a fixing ring 401 which is sleeved and fixed on the outside of the main shaft 302, a second spring 402 is fixedly connected between the fixing ring 401 and the inner surface of the sealing shell 301, the second spring 402 is sleeved on the outside of the main shaft 302, a cutter head 403 is fixedly connected to the top of the main shaft 302, and the cutter head 403 is slidably installed inside the sealing shell 301 and passes through the top of the sealing shell 301.

[0044] In this embodiment: when the water spray pipe 202 cannot be drilled out of the compacted soil, the user needs to continue to increase the water pressure inside the main water pipe 1. The continuously increased water pressure will further push the cross spring piece 303 and the main shaft 302 until the main shaft 302 overcomes the resistance of the second spring 402 and moves vertically and drives the cutter head 403 to move synchronously and push out from the top of the sealing shell 301. At this time, the water distribution pipe 201 and the water spray pipe 202 pushed by the spiral blade 203 will synchronously drive the exposed cutter head 403 to rotate, thereby stirring the soil outside the sealing shell 301 and assisting the water spray pipe 202 to break out of the soil. Among them, a number of evenly distributed second elastic members 404 are fixedly connected between the fixing ring 401 and the cross spring piece 303, which are used to further provide elastic force to drive the cross spring piece 303 to reset and bounce, and a circular groove 405 is opened through the top of the sealing shell 301, and the circular groove 405 is evenly distributed on the outside of the cutter head 403 to provide more space for the water flow to be sprayed out.

[0045] Working principle: Under normal circumstances, the water spray pipe 202 is hidden forty to sixty centimeters below the ground surface. When water flows into the main water pipe 1, the high-pressure water flow will enter the inside of the water branch pipe 201 through the main water pipe 1, and use the water pressure to push the spiral blade 203, causing the spiral blade 203 to drive the water branch pipe 201 and the water spray pipe 202 to rotate. At the same time, the water flow inside the main water pipe 1 will push the water spray pipe 202 to move vertically along the inside of the water branch pipe 201, thereby pushing out of the soil and the water flow sprayed from the top of the water spray pipe 202 will be sprayed out through the hollow main shaft 302. When the user controls the water pressure inside the main water pipe 1 to increase, the water flow sprayed from the top of the water spray pipe 202 will expand and spray to the lower surface of the cross spring piece 303. At the same time, the strong water pressure will push the cross spring piece 303, causing the middle part of the cross spring piece 303 to push upward, and the cross spring piece 303 will push upward at the same time. The end of the sheet 303 will press down the cover plate 304, causing all the cover plates 304 to move downward, exposing the water outlet holes 305 on the inner wall of the sealing shell 301, and the water flow sprayed from the top of the water spray pipe 202 will move along the deformed surface of the cross spring piece 303 and be sprayed out from a plurality of water outlet holes 305, resulting in two water outlet modes of the device, one is to spray directly from the top of the sealing shell 301 in the form of a water column, and the other is to spray from the side of the sealing shell 301 in the form of a dispersed mist; when the water spray pipe 202 cannot be drilled out of the compacted soil, the user needs to continue to increase the water pressure inside the main water pipe 1, and the continuously increased water pressure will further push the cross spring piece 303 and the main shaft 302 until the main shaft 302 overcomes the resistance of the second spring 402 and moves vertically and drives the cutter head 403 to move synchronously and be ejected from the top of the sealing shell 301. The specific state is as follows Figure 5As shown; at this time, the water distribution pipe 201 and the water spray pipe 202 driven by the spiral blade 203 will synchronously drive the exposed cutter head 403 to rotate, thereby stirring the soil outside the sealing shell 301 and assisting the water spray pipe 202 to break out of the soil.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
