Description

Technical Field

[0001] The invention relates to the technical field of sprinkler irrigation machines, in particular to an automatic hose reeling device for a fast-retracting winch-type sprinkler irrigation machine. Background Art

[0002] Sprinkler irrigation is an advanced irrigation technology that has the advantages of saving water, labor, and land, increasing production, and strong adaptability. Promoting sprinkler irrigation is one of the important measures to achieve water conservancy and promote agricultural production. Capstan sprinkler, also known as reel sprinkler, uses a reel-wound hose to pull a long-range sprinkler head, allowing the sprinkler head to move along the operation route during the sprinkler irrigation process. When using an existing sprinkler, it is necessary to first place the reel in the farmland, move the sprinkler head to a certain distance, and then carry out irrigation and spraying. At the same time, the sprinkler head is moved toward the reel through the hose. However, when the sprinkler head is stuck, especially when the farmland has a slope, the reel is easy to move, resulting in changes in the tension on the hose, affecting the operation of the device. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic pipe winding device for a fast-retracting winch-type sprinkler irrigation machine, which utilizes the counterclockwise rotation of the winding roller and the counterclockwise rotation of the striking hammer to strike the shock-absorbing plate and the fixing pin, and insert the fixing pin deeper into the soil, thereby preventing the device from moving due to strong winds or other conditions during operation, thereby affecting the subsequent winding of the PE pipe and the winding accuracy of the device, and ensuring the normal operation of the device.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatic hose reeling device for a fast-retracting winch-type sprinkler, comprising a reeling roller, a reeling mechanism provided at the lower end of the reeling roller, a PE tube wound around the reeling roller, the reeling mechanism comprising a fixed plate provided on the outer side of the reeling roller, a control box fixedly provided on one side of the fixed plate, a first fixed column fixed on one side of the reeling roller, a connecting column rotatably provided on one side of the first fixed column, a movable seat fixed on the bottom of the fixed plate, a fixing pin movably provided on one end of the movable seat, a second fixed column fixed on the other end of the movable seat, the PE tube passing through the second fixed column and connected to a water spraying mechanism; The water spraying mechanism includes a mobile vehicle arranged outside a section of the PE pipe, one side of the mobile vehicle is connected to a water spraying pipe, one side of the water spraying pipe is rotated with a control valve, and the bottom of the water spraying pipe is also connected to a cleaning pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes the counterclockwise rotation of the winding roller and the knocking hammer to knock the shock-absorbing plate and the fixing pin counterclockwise, so as to insert the fixing pin deeper into the soil, thereby preventing the device from moving due to strong winds or other conditions during operation, thereby affecting the subsequent winding of the PE pipe and the winding accuracy of the device, thereby ensuring the normal operation of the device.

[0014] The present invention drives the first fixed column to rotate clockwise when the winding roller rotates clockwise, drives the connecting column and the knocking hammer to rotate, and when the knocking hammer rotates clockwise, the fixed pin is knocked from the lower end of the fixed pin.

[0018] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See Figures 1 to 8As shown, the present invention provides an automatic hose reeling device for a fast-retracting capstan-type sprinkler, comprising a reeling roller 1, a reeling mechanism 2 being provided at the lower end of the reeling roller 1, a PE tube 11 being wound around the reeling roller 1, the reeling mechanism 2 comprising a fixing plate 24 provided on the outer side of the reeling roller 1, a control box 23 being fixedly provided on one side of the fixing plate 24, a first fixing post 21 being fixed on one side of the reeling roller 1, a connecting post 22 being rotatably provided on one side of the first fixing post 21, a movable seat 28 being fixed on the bottom of the fixing plate 24, a fixing pin 216 being movably provided at one end of the movable seat 28, a second fixing post 211 being fixed at the other end of the movable seat 28, the PE tube 11 passing through the second fixing post 211 and being connected to the water spraying mechanism 3; The water spraying mechanism 3 includes a mobile vehicle 31 arranged outside one end of the PE pipe 11. A water spraying pipe 33 is connected to one side of the mobile vehicle 31. A control valve 34 is rotated on one side of the water spraying pipe 33. A cleaning pipe 38 is also connected to the bottom of the water spraying pipe 33.

[0020] Before using this device, fill the PE pipe 11 with water through the external water source box. When the farmland needs to be irrigated, first stop the device at the farmland that needs to be sprinkled, and drive the mobile vehicle 31 to move by the motor. At the same time, the winding roller 1 follows the movement of the mobile vehicle 31 to lay the PE pipe 11 rolled up on the winding roller 1. At the same time, when working, the control box 23 controls the winding roller 1 to rotate counterclockwise. The counterclockwise rotation of the winding roller 1 drives the first fixed column 21 to rotate counterclockwise, drives the connecting column 22 to rotate, and the rotation of the connecting column 22 drives the knocking hammer 27 to rotate, and the knocking hammer 27 is driven by the hammer 27. The hammer 27 rotates one circle and collides with the shock-absorbing plate 215 on one side of the winding roller 1, causing the shock-absorbing plate 215 to be knocked, and at the same time drives the fixing pin 216 to move downward and insert into the soil. At the same time, the winding roller 1 continues to rotate, driving the hammer 27 to continuously knock the shock-absorbing plate 215 and the fixing pin 216, inserting the fixing pin 216 deeper into the soil, to avoid strong winds or other conditions during operation that cause the device to move, thereby affecting the subsequent winding of the PE pipe 11 and the winding accuracy of the device, ensuring the normal operation of the device.

[0021] When paving is completed and sprinkler irrigation is required, the control box 23 is used to control the winding roller 1 to rotate clockwise. When the winding roller 1 rotates clockwise, it drives the first fixed column 21 to rotate clockwise, and drives the connecting column 22 and the knocking hammer 27 to rotate. When the knocking hammer 27 rotates clockwise, the fixed pin 216 is knocked from the lower end of the fixed pin 216. During the winding process, the lower end of the fixed pin 216 is continuously knocked to pull out the fixed pin 216 inserted into the soil, so that the device can travel normally and continue with the next set of work.

[0022] At the same time, during the winding process, the staff manually rotates the control valve 34 and controls the electric valve 39 to open through the control box 23. At the same time, one end of the PE tube 11 is restricted at a high position by the second fixed column 211, so that the residual water in the PE tube 11 is gathered at one end of the second fixed column 211. At the same time, the hammer 27 strikes the fixed pin 216, so that the hammer 27 is subjected to a certain force, and the PE tube 11 is swung to a certain extent, so that the residual water in the PE tube 11 is cleaned and the residual water in the PE tube 11 is reduced. At the same time, the residual water in the PE tube 11 enters the cleaning pipe 38 through the electric valve 39 to clean the second moving wheel 35 and reduce the residual mud blocks on the second moving wheel 35, thereby avoiding the uneven diameter of the second moving wheels 35 on both sides after being contaminated with mud blocks, thereby affecting the winding of the PE tube 11 by the device.

[0023] In an optional embodiment, the winding roller 1 is connected to the output end of the motor, the motor is electrically connected to the control box 23 , and the winding roller 1 rotates inside the fixed plate 24 .

[0024] It should be noted that the rotation of the winding roller 1 is controlled by the control box 23 to ensure the normal operation of the device and avoid excessive speed during winding, which may cause damage to the PE pipe 11. At the same time, the winding roller 1 is restricted by the fixed plate 24 to prevent the rotation of the winding mechanism 2 from deviating from the track and affecting the winding of the PE pipe 11.

[0025] In an optional embodiment, a limiting column 25 is fixed to one side of the first fixing column 21 , the connecting column 22 rotates on the limiting column 25 , an auxiliary sleeve 26 is fixed to the outside of the limiting column 25 , and a striking hammer 27 is fixed to one end of the connecting column 22 .

[0026] It should be noted that the connecting column 22 is restricted by the limiting column 25 to prevent the hammer 27 from hitting the shock absorbing plate 215 with excessive strength, which may affect the connection relationship between the connecting column 22 and the limiting column 25, thereby causing the hammer 27 to be damaged during operation, thereby affecting the operation of the device. At the same time, when the connecting column 22 rotates on the limiting column 25 so that the hammer 27 hits the shock absorbing plate 215, the connecting column 22 can rotate on the limiting column 25 to prevent the hammer 27 and the shock absorbing plate 215 from getting stuck, thereby affecting the rotation of the winding roller 1, and then affecting the winding of the winding roller 1. At the same time, the connection between the connecting column 22 and the limiting column 25 is protected by the auxiliary sleeve 26 to avoid damage.

[0027] In an optional embodiment, a reciprocating screw 212 rotates on one side of the fixed plate 24 , a fixed sleeve 213 is movable on the upper end of the reciprocating screw 212 , the PE pipe 11 passes through the fixed sleeve 213 , and the reciprocating screw 212 is electrically connected to the control box 23 .

[0028] It should be noted that the rotation of the reciprocating screw 212 is controlled by the control box 23, and the rotation of the reciprocating screw 212 is adjusted following the rotation of the winding roller 1. At the same time, when the reciprocating screw 212 rotates, it drives the fixed sleeve 213 to move back and forth, and straightens the PE tube 11 wound on the winding roller 1, so as to avoid the PE tube 11 from piling up on the winding roller 1 during winding and affecting the rotation of the winding roller 1. At the same time, the PE tube 11 is easily stretched and bent, which affects the service life of the PE tube 11.

[0029] In an optional embodiment, a fixing frame 210 is fixed to one end of the movable base 28 , and a second fixing column 211 is provided on the fixing frame 210 .

[0030] It should be noted that when winding, the second fixed column 211 is used to guide the residual water from the sprinkler irrigation inside the PE tube 11 to prevent the water in the PE tube 11 from flowing through the second fixed column 211, and the water is collected at one end of the second fixed column 211 for subsequent use. At the same time, the residual moisture in the PE tube 11 is reduced to avoid damage to the PE tube 11 during storage.

[0031] In an optional embodiment, first moving wheels 29 are rotatably provided on both sides of the moving base 28 , a limiting sleeve 214 is provided at one end of the moving base 28 , and auxiliary wheels are rotatably provided on both sides of the limiting sleeve 214 .

[0032] It should be noted that the device is moved by the first moving wheel 29 and the auxiliary wheel, which facilitates the device to work in different working positions, reduces the labor intensity of the staff, and improves the convenience of work.

[0033] In an optional embodiment, the limiting sleeve 214 is movably connected to the fixing pin 216 , and a shock absorbing plate 215 is fixed to the upper end of the fixing pin 216 .

[0034] It should be noted that by inserting the fixing pin 216 into the limiting sleeve 214 and striking the fixing pin 216 during operation, the fixing pin 216 is made to enter the soil, thereby fixing the device to prevent the device from moving during operation, which affects the winding and may cause pulling forces in different directions to the PE pipe 11, thereby affecting the service life of the PE pipe 11. At the same time, the shock-absorbing plate 215 cushions the impact of the striking hammer 27 to avoid excessive noise during operation, reduce damage to the fixing pin 216, and extend the service life of the fixing pin 216.

[0035] In an optional embodiment, a connecting plate 32 is provided on one side of the mobile vehicle 31 , and one end of the connecting plate 32 is connected to the water spray pipe 33 .

[0036] It should be noted that the PE pipe 11 is connected to the mobile vehicle 31 through the second fixed column 211, enters the water spray pipe 33 through the connecting plate 32, and is sprayed out through the water spray pipe 33 to irrigate the farmland. At the same time, the mobile vehicle 31 is connected to the winding roller 1 through the PE pipe 11, which facilitates the recovery of the mobile vehicle 31.

[0037] In an optional embodiment, a baffle 341 is provided at one end of the control valve 34 passing through the water spray pipe 33, an electric valve 39 is provided inside the cleaning pipe 38, the electric valve 39 is electrically connected to the control box 23, a fixed rod 37 is provided on one side of the mobile vehicle 31, and a limiting wheel 36 is provided for rotation at the bottom of the fixed rod 37.

[0038] It should be noted that the switch of the water spray pipe 33 is controlled by rotating the control valve 34. When the control valve 34 is rotated during winding, the rotation of the control valve 34 drives the baffle 341 to rotate, closing the connection between the water spray pipe 33 and the outside world. At the same time, the electric valve 39 is opened by the control box 23, so that the water in the water spray pipe 33 and the PE pipe 11 is discharged through the cleaning pipe 38, and the second moving wheel 35 is cleaned. At the same time, the mobile vehicle 31 is restricted by the limiting wheel 36, so that when the PE pipe 11 is wound, the limiting wheel 36 moves along the PE pipe 11 during discharge, thereby ensuring that the mobile vehicle 31 moves in a straight line during winding.

[0039] Working principle: Before using this device, fill the PE pipe 11 with water through the external water source box. When the farmland needs to be irrigated, first stop the device at the farmland that needs sprinkler irrigation, and drive the first moving wheel 29 to rotate by the motor to drive the moving vehicle 31 to move. At the same time, the winding roller 1 follows the movement of the moving vehicle 31 to lay the PE pipe 11 rolled up on the winding roller 1. At the same time, when working, the control box 23 controls the motor to drive the winding roller 1 to rotate counterclockwise, and the winding roller 1 rotates counterclockwise to drive the first fixed column 21 to rotate counterclockwise, and drives the connecting column 22 to rotate. The rotation of the connecting column 22 drives the knocking hammer 27 to rotate. The knocking hammer 27 rotates one circle and collides with the shock-absorbing plate 215 on one side of the winding roller 1, so that the shock-absorbing plate 215 is knocked, and at the same time drives the fixed pin 216 to move downward and insert into the soil. At the same time, the winding roller 1 continues to rotate, driving the knocking hammer 27 to continuously knock on the shock-absorbing plate 215 and the fixed pin 216.

[0040] When paving is completed and sprinkler irrigation is required, the control box 23 controls the motor to drive the winding roller 1 to rotate clockwise. When the winding roller 1 rotates clockwise, it drives the first fixed column 21 to rotate clockwise, and drives the connecting column 22 and the knocking hammer 27 to rotate. When the knocking hammer 27 rotates clockwise, the fixing pin 216 is knocked from the lower end of the fixing pin 216. During the winding process, the lower end of the fixing pin 216 is continuously knocked to pull out the fixing pin 216 inserted into the soil.

[0041] At the same time, during the winding process, the staff manually rotates the control valve 34, and at the same time controls the electric valve 39 to open through the control box 23. At the same time, the PE pipe 11 is restricted to a high position near one end of the mobile vehicle 31 through the second fixed column 211, so that the residual water in the PE pipe 11 is gathered at one end of the second fixed column 211. At the same time, the hammer 27 strikes the fixed pin 216, so that the hammer 27 is subjected to a certain force, and the PE pipe 11 is swung to a certain extent, thereby cleaning the residual water in the PE pipe 11 and reducing the residual water in the PE pipe 11. At the same time, the residual water in the PE pipe 11 enters the cleaning pipe 38 through the electric valve 39, and is sprayed out through the cleaning pipe 38 to clean the second moving wheel 35.

[0042] The connecting column 22 is restricted by the limiting column 25 to prevent the hammer 27 and the shock-absorbing plate 215 from hitting with excessive strength to affect the connection relationship between the connecting column 22 and the limiting column 25. The reciprocating screw rod 212 is controlled to rotate by the control box 23. The rotation of the reciprocating screw rod 212 is adjusted following the rotation of the winding roller 1. At the same time, the reciprocating screw rod 212 drives the fixed sleeve 213 to move back and forth when rotating, and straightens the PE pipe 11 wound on the winding roller 1. When winding, the second fixed column 211 is used to guide the residual water of the sprinkler irrigation inside the PE pipe 11 to prevent the water in the PE pipe 11 from flowing through the second fixed column 211. The water is collected at one end of the second fixed column 211, and the device is moved by the first moving wheel 29 and the auxiliary wheel.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
