DETAILED DESCRIPTION
[0023] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.
[0024] Example 1:
[0025] like Figure 1 As shown, a liquid fertilizer irrigation device of the present invention includes a horizontal plate 1, and a liquid tank 2 is installed on the top of the horizontal plate 1 to store liquid fertilizer (for example: Sanan Tianlibao microbial inoculant, which adopts complete nutrients, fast dissolution and good absorption, and effectively solves many problems such as organic matter and trace elements being difficult to dissolve in water, difficult to absorb and having low utilization rate). A suction pump 3 is installed on one side of the liquid tank 2 and connected to the liquid tank 2, so that the liquid fertilizer can be extracted from the liquid tank 2 and discharged under pressure. Then, a connecting lifter 4 is installed on one side of the horizontal plate 1, and a spray nozzle is connected to the outside of the lifter 4. Spraying pipe column 5, when the spraying pipe column 5 needs to adjust the irrigation height for different crops, the control lifter 4 can drive the spraying pipe column 5 to rise or fall along the lifter 4 to achieve the effect of quickly adjusting the height, and the spraying pipe column 5 can also be horizontally expanded to increase the irrigation range at any time, and a shock-absorbing wheel group 6 is installed at the bottom of the horizontal plate 1. The shock-absorbing wheel group 6 can make the irrigation device as a whole move in the field, and can ensure the stability of the irrigation device when encountering muddy and potholes. At the same time, the outer part of the shock-absorbing wheel group 6 can achieve the effect of easy escape, avoiding getting stuck inside the ground.
[0026] like Figure 2 As shown, by providing a lifting bracket 401 and a rotating groove 4011, the lifting screw 402 can be installed inside it and be in a state of rotating in place. By providing a large turntable 4021, the lifting screw 402 can be driven to rotate when the large turntable 4021 is rotated. The lifting ball rod 403 installed on the outside of the lifting screw 402 can perform vertical lifting and lowering movements along the lifting screw 402 under the action of the guide groove 4012.
[0027] like Figure 3 As shown, by setting the screw groove 4031, it can be movably connected to the outside of the lifting screw 402, so that the lifting ball rod 403 can be raised and lowered when the lifting screw 402 rotates. The setting of the ball groove 4032 can make the spray pipe column 5 connected to its interior and can be rotated to a certain angle.
[0028] A guide post 4033 is provided on the outside of the screw groove 4031 end of the lifting ball rod 403. The guide post 4033 is inserted into the guide groove 4012. When the lifting screw rod 402 rotates, the screw groove 4031 does not rotate, so that the lifting ball rod 403 can slide up and down along the guide groove 4012.
[0029] like Figure 4As shown, a plurality of nozzles 501 are provided on the outside of the spraying column 5 for spraying liquid fertilizer. A small turntable 502 is provided to control the opening of the horizontal and lateral rotation of the spraying column 5. The universal ball head 503 can be engaged with the lifting ball rod 403 so that the spraying column 5 can be rotated to adjust a certain angle. Finally, the arrangement of the telescopic tube 504 allows the delivery of liquid fertilizer to be unaffected when the spraying column 5 is rotated at will.
[0030] During implementation, after the liquid fertilizer irrigation device moves to the designated area for irrigation, if the crop needs to be fertilized and irrigated at its roots, the large turntable 4021 is held by hand to rotate the lifting screw 402, so that the rotating head 4022 rotates in place inside the rotating groove 4011, so that the outer side of the lifting screw 402 and the screw groove 4031 rotate, and the guide column 4033 of the lifting ball rod 403 is inserted into the guide groove 4012. Under the limiting action of the guide groove 4012, the lifting ball rod 403 is pushed to rise and fall vertically along the outer side of the lifting screw 402. At this time, the lifting and lowering of the lifting ball rod 403 can drive the spraying pipe column 5 to rise and fall, and move to the roots of the crop. By starting the suction pump 3, the liquid fertilizer inside the liquid tank 2 is extracted, pressurized, and then transported It is sent to the inside of the telescopic tube 504 and finally enters the inside of the nozzle 501 and is sprayed out from one end of the nozzle 501. At this time, the spraying column 5 is spraying in the horizontal and vertical directions. If it is necessary to expand the spraying irrigation range of the spraying column 5, the small turntable 502 can be turned to rotate the spraying column 5 around one end of the universal ball head 503, so that the spraying column 5 is rotated into a horizontal direction, the direction of the nozzle 501 is changed, and the irrigation range is increased. Finally, by rotating one end of the universal ball head 503 inside the ball groove 4032, the direction angle of the nozzle 501 can also be changed to a certain extent, making spraying irrigation more convenient. At the same time, the spraying irrigation height and range angle of the liquid fertilizer can be quickly adjusted to improve irrigation efficiency.
[0031] Example 2:
[0032] like Figure 5 As shown, based on the first embodiment, the utility model provides a technical solution: by providing a linkage 601, the shock-absorbing wheel group 6 can be installed at the bottom of the cross plate 1, and a shock absorber 602 can provide shock absorption for the wheel hub 603, and the wheel hub 603 can ensure that it is not easy to get stuck when moving on muddy roads.
[0033] like Figure 6 As shown, the connecting rod 6011 can be connected to the shock absorber 602, and a rotating shaft 6012 is provided to connect with the connecting rod 6011, so that the connecting rod 6011 can rotate.
[0034] like Figure 1 and Figure 7As shown, a handle 7 is connected to one end of the horizontal plate 1 to push the wheel hub 603 to move. By providing a protruding block 6031 on the outside of the wheel hub 603, the direct contact area between the wheel hub 603 and the ground can be reduced, and the staggered arrangement makes it easy to get out of trouble and not easy to stick to the ground.
[0035] During implementation, when liquid fertilizer is irrigated to the outside of the crops, holding the outer side of the handle 7 and pushing the horizontal plate 1 can cause the wheel hub 603 to be pressed and thrust to rotate while driving the horizontal plate 1 to move. When encountering a bumpy ground, the wheel hub 603 will sink or rise and cause the shock absorber 602 to sink or rise together. At this time, the shock absorber 602 will push the connecting rod 6011 to rotate around the rotating shaft 6012. The rotation of the connecting rod 6011 prevents the linkage 601 from lifting the bottom of the horizontal plate 1, thereby ensuring that one side of the horizontal plate 1 will not produce ups and downs due to the sinking or rising of the wheel hub 603, affecting the stability, preventing tilt and causing the entire irrigation device to tip over, prompting the stability of irrigation, and finally, through the setting of the protruding block 6031, the wheel hub 603 is easier to get out of the muddy ground, and is not easy to get stuck in the ground, which improves the efficiency of the movement of the irrigation device.
[0036] The advantages of this technical solution in practical applications include but are not limited to the following:
[0037] 1. The rotational connection between the lifting screw 402 and the lifting ball rod 403 allows the spray column 5 to be quickly raised and lowered to change the irrigation height. The cooperation between the small turntable 502 and the universal ball head 503 allows the spray column 5 to be expanded from a horizontal vertical direction to a horizontal horizontal direction, thereby increasing the irrigation range.
[0038] 2. The setting of the linkage 601 can make the horizontal plate 1 more stable during movement, preventing liquid fertilizer from spilling. At the same time, the raised block 6031 prevents the wheel hub 603 from sinking into the ground during rotation, thereby improving irrigation efficiency.
[0039] When the liquid fertilizer is irrigated to the outside of the crops by the present technical solution, the outer side of the handle 7 is held by the hand to push the horizontal plate 1, so that the hub 603 is pressed and thrust is applied to rotate, and the horizontal plate 1 is driven to move at the same time. When encountering a pothole, the hub 603 will sink or rise and cause the shock absorber 602 to sink or rise together. At this time, the shock absorber 602 will push the connecting rod 6011 to rotate around the rotating shaft 6012. The rotation of the connecting rod 6011 prevents the linkage 601 from lifting the bottom of the horizontal plate 1, thereby ensuring that one side of the horizontal plate 1 will not be affected by the sinking or rising of the hub 603. The high and low fluctuations that affect the stability are prevented, and the tilting that causes the entire irrigation device to fall over is prevented, which prompts the stability of irrigation. Finally, the setting of the protruding block 6031 makes it easier for the wheel hub 603 to get out of the muddy ground and not easily get stuck inside the ground, which improves the efficiency of the movement of the irrigation device. After the liquid fertilizer irrigation device moves to the designated area for irrigation, if the crop needs to be fertilized and irrigated at its roots, the lifting screw 402 is rotated by holding the large turntable 4021, so that the rotor 4022 rotates in place inside the rotating groove 4011. The outer side of the lifting screw 402 and the screw groove 4031 rotate, thereby pushing the lifting ball rod 403 to rise and fall vertically along the outer side of the lifting screw 402. At this time, the lifting of the lifting ball rod 403 can drive the spraying column 5 to rise and fall, and move to the roots of the crops. By starting the suction pump 3, the liquid fertilizer inside the liquid tank 2 is extracted and pressurized and transported to the inside of the telescopic tube 504, and finally enters the inside of the nozzle 501 and is sprayed out from one end of the nozzle 501. At this time, the spraying column 5 is in the horizontal and vertical directions of spraying. If necessary To increase the spraying range of the spray column 5, the small turntable 502 can be used to rotate the spray column 5 around one end of the universal ball head 503, so that the spray column 5 is rotated to a horizontal position, and the direction of the nozzle 501 is changed, thereby increasing the irrigation range. Finally, by rotating one end of the universal ball head 503 in the ball groove 4032, the direction angle of the nozzle 501 can be changed to a certain extent, making spraying irrigation more convenient. At the same time, the spraying height and range angle of the liquid fertilizer can be quickly adjusted to improve irrigation efficiency.
