Specific implementation manners
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Embodiment 1;
[0028] Referring to the attached Figures 1-4 , a soil fertilizer warning device in this embodiment includes a controller, an alarm, a nitrogen content sensor, a top plate and an outer shell. The alarm, the controller and the nitrogen content sensor are communicatively connected; the bottom of the top plate is fixedly connected to the outer shell. A through hole is provided at the bottom of the outer shell, and a nitrogen content sensor and a moving component are arranged inside the outer shell. One end of the moving component is connected to the nitrogen content sensor, and the other end extends out of the top plate so as to drive the nitrogen content sensor to pass through the through hole and insert into the soil through the moving component, so as to detect and give an alarm to the nitrogen element content in the soil.
[0029] Specifically, the warning device includes a top plate 1, and the bottom of the top plate 1 is fixedly connected with a housing 3; one side of the housing 3 is fixedly connected with a controller 4, and the controller 4 is selected according to actual needs as long as it meets the working requirements; the other side of the housing 3 is fixedly connected with an alarm 5, and the alarm 5 is selected according to actual needs as long as it meets the working requirements; a nitrogen content sensor 7 is arranged inside the housing 3, and the nitrogen content sensor 7 is selected according to actual needs as long as it meets the working requirements. The nitrogen content sensor 7 detects the nitrogen content in the field soil, and the nitrogen content sensor 7, the controller 4 and the alarm 5 are communicatively connected:
[0030] When the nitrogen element in the field soil does not exceed the preset amount, the nitrogen content sensor 7 will not transmit a signal to the controller 4, and the alarm 5 will not make a sound. The staff can conclude that the nitrogen element in this piece of field soil does not exceed the standard, and chemical fertilizer can be applied;
[0031] When the nitrogen content sensor 7 detects that the nitrogen element content in the field soil exceeds the preset amount, the nitrogen content sensor 7 transmits the signal to the controller 4, and the controller 4 then transmits the signal to the alarm 5. The alarm 5 makes a sound, and the staff can conclude that the nitrogen element in this piece of field soil exceeds the standard and chemical fertilizer does not need to be applied, avoiding the situation of random fertilization.
[0032] A moving component is also arranged inside the housing 3. The moving component includes a turntable 8, a lead screw 9, a lead screw nut 10, a cross column 11, a connecting column 6 and a sliding column 12. The top of the lead screw 9 is fixedly connected with the turntable 8. The staff rotates the turntable 8, and the turntable 8 drives the lead screw 9 to rotate. The outer wall of the lead screw 9 is rotatably connected to the inner wall of the top plate 1 through a bearing. The outer wall of the lead screw 9 is threadedly connected with the lead screw nut 10. The lead screw 9 drives the lead screw nut 10 to move. The outer wall of the lead screw nut 10 is fixedly connected with the cross column 11. The lead screw nut 10 drives the cross column 11 to descend. The bottom of the cross column 11 is fixedly connected with the connecting column 6. The cross column 11 drives the connecting column 6 to descend. The bottom of the connecting column 6 is fixedly connected with the nitrogen content sensor 7. The connecting column 6 drives the nitrogen content sensor 7 to descend, and the nitrogen content sensor 7 is inserted into the field soil. A sliding column 12 is slidably clamped on the inner wall of the side of the cross column 11 away from the lead screw 9. The cross column 11 slides on the sliding column 12, and the top of the sliding column 12 is fixedly connected to the bottom of the outer wall of the top plate 1.
[0033] In the specific implementation process, it is particularly worth noting that the controller 4 is selected according to actual needs as long as it can meet the working requirements, the alarm 5 is selected according to actual needs as long as it can meet the working requirements, the nitrogen content sensor No. 7 is selected according to actual needs as long as it can meet the working requirements. The nitrogen content sensor 7 detects the nitrogen content in the field soil. If the nitrogen element in the field soil does not exceed the preset amount, the nitrogen content sensor 7 will not transmit a signal to the controller 4, and the alarm 5 will not make a sound. The staff can conclude that the nitrogen element in this piece of field soil does not exceed the standard and chemical fertilizer can be applied. If the nitrogen content sensor 7 detects that the nitrogen element content in the field soil exceeds the preset amount, the nitrogen content sensor 7 will transmit the signal to the controller 4, and the controller 4 will then transmit the signal to the alarm 5. The alarm 5 makes a sound, and the staff can conclude that the nitrogen element in this piece of field soil exceeds the standard and chemical fertilizer does not need to be applied, avoiding the situation of random fertilization. The staff rotates the turntable 8, and the turntable 8 drives the lead screw 9 to rotate. Since the lead screw nut 10 is circumferentially rotationally positioned by the cross column 11, therefore, the lead screw 9 can only drive the lead screw nut 10 to move. The lead screw nut 10 drives the cross column 11 to descend, the cross column 11 drives the connecting column 6 to descend, and the connecting column 6 drives the nitrogen content sensor 7 to descend, inserting the nitrogen content sensor 7 into the field soil. The cross column 11 slides on the sliding column 12 to realize the detection and alarm of the nitrogen element inside the field soil.
[0034] Preferably, handlebars 2 are fixedly connected to the inner walls on both sides of the top plate 1. When the staff moves the entire warning device, the staff holds the handlebars 2 on both sides, moves the handlebars 2, and the handlebars 2 drive the top plate 1 to move. The handlebars 2 facilitate the staff to move the entire warning device.
[0035] In an alternative embodiment, through holes 20 are formed in the bottom of the housing 3. When the nitrogen content sensor 7 descends, the nitrogen content sensor 7 passes through the through holes 20 and is inserted into the soil inside the field.
[0036] In a further technical solution, a plurality of ground nails 13 are fixedly connected to the outer bottom of the housing 3. When the entire warning device moves to the position to be detected, due to gravity, the ground nails 13 are inserted into the soil to fix the housing 3.
[0037] In the specific implementation process, it is particularly worth noting that when the entire warning device moves to the position to be detected, due to gravity, the ground nails 13 are inserted into the soil to fix the housing 3, which facilitates the staff to rotate the turntable 8.
[0038] A cover body 17 is attached to the bottom of the outer shell 3. When the staff moves the entire warning device, the staff makes the top of the cover body 17 contact the bottom of the outer shell 3; connecting plates 18 are fixedly connected to both sides of the cover body 17. The cover body 17 drives the connecting plates 18 to move. The outer walls of the two connecting plates 18 are attached to the outer wall of the outer shell 3. Iron sheets 21 are fixedly connected to the inner walls of the two connecting plates 18. The two connecting plates 18 drive the iron sheets 21 to move. Magnets 19 are attached to the outer walls of the outer shell 3 on the sides away from the connecting plates 18 of the two iron sheets 21. When the two iron sheets 21 move to the positions of the magnets 19, due to the magnetism of the magnets 19 themselves, the iron sheets 21 are adsorbed, and the cover body 17 is fixed. The cover body 17 covers the ground nails 13, and the outer walls of the two magnets 19 are fixedly connected to the inside of the outer shell 3.
[0039] In the specific implementation process, it is particularly worth noting that when the staff moves the entire warning device, the staff makes the top of the cover body 17 contact and abut against the bottom of the outer shell 3. The cover body 17 drives the connecting plates 18 to move, and the two connecting plates 18 drive the iron sheets 21 to move. When the two iron sheets 21 move to the positions of the magnets 19, due to the magnetism of the magnets 19 themselves, the iron sheets 21 are adsorbed, and the cover body 17 is fixed. The cover body 17 covers the ground nails 13 to protect the staff and prevent the exposed ground nails 13 from scratching the staff.
[0040] Specifically, when it is necessary to detect and give an early warning of the chemical fertilizer content in the field soil, first, the staff makes the top of the cover body 17 contact with the bottom of the outer shell 3. The cover body 17 drives the connecting plate 18 to move, and the connecting plates 18 on both sides drive the iron sheet 21 to move. When the iron sheets 21 on both sides move to the position of the magnet 19, since the magnet 19 itself has magnetism, it adsorbs the iron sheet 21 and fixes the cover body 17. The cover body 17 covers the ground nail 13 to protect the staff, and the staff moves the whole warning device to the field; then the cover body 17 is removed. Due to gravity, the ground nail 13 is inserted into the soil to fix the outer shell 3. Then the staff rotates the turntable 8. The turntable 8 drives the lead screw 9 to rotate. The lead screw 9 drives the lead screw nut 10 to move. The lead screw nut 10 drives the cross column 11 to descend. The cross column 11 slides on the sliding column 12. The cross column 11 drives the connecting column 6 to descend. The connecting column 6 drives the nitrogen content sensor 7 to descend. The nitrogen content sensor 7 is inserted into the field soil to detect the nitrogen content in the field soil. If the nitrogen element in the field soil does not exceed the preset amount, the nitrogen content sensor 7 will not transmit a signal to the controller 4, and the alarm 5 will not make a sound. The staff can conclude that the nitrogen element in this piece of field soil does not exceed the standard and chemical fertilizer can be applied. If the nitrogen content sensor 7 detects that the nitrogen element content in the field soil exceeds the preset amount, the nitrogen content sensor 7 transmits the signal to the controller 4, and the controller 4 then transmits the signal to the alarm 5. The alarm 5 makes a sound. The staff can conclude that the nitrogen element in this piece of field soil exceeds the standard and chemical fertilizer does not need to be applied.
[0041] Embodiment 2;
[0042] Referring to the attached Figures 1-3 As shown, on the basis of Embodiment 1, a pin 14 is penetrated through the inner wall of the turntable 8. After the staff finishes rotating the turntable 8, the staff moves the pin 14, inserts the pin 14 into the turntable 8 and is movably connected to the pin 14. Both sides of the end of the pin 14 away from the turntable 8 are fixedly connected with convex blocks 15. The pin 14 drives the convex blocks 15 to move. The outer walls of the two convex blocks 15 are both in fit with the inner wall of the rubber sleeve 16. The bottom of the pin 14 is in fit with the inner wall of the rubber sleeve 16. The pin 14 and the convex blocks 15 are inserted into the inside of the rubber sleeve 16. Through the friction force of the rubber sleeve 16, the pin 14 is fixed, thereby limiting the turntable 8. The outer wall of the rubber sleeve 16 is fixedly connected to the inner wall of the top plate 1 so that the rubber sleeve 16 and the top plate 1 are in interference fit.
[0043] In the specific implementation process, after the staff member finishes rotating the turntable 8, the staff member moves the bolt 14, inserts the bolt 14 into the turntable 8, the bolt 14 drives the convex block 15 to move, the bolt 14 and the convex block 15 are inserted into the inside of the rubber sleeve 16, and the bolt 14 is fixed through the frictional force of the rubber sleeve 16, thereby limiting the turntable 8 and preventing the turntable 8 from rotating;
[0044] Specifically, after the staff member finishes rotating the turntable 8, the staff member moves the bolt 14, inserts the bolt 14 into the turntable 8, the bolt 14 drives the convex block 15 to move, the bolt 14 and the convex block 15 are inserted into the inside of the rubber sleeve 16, and the bolt 14 is fixed through the frictional force of the rubber sleeve 16, thereby limiting the turntable 8 and preventing the turntable 8 from rotating. When the staff member needs to rotate the turntable 8, the staff member pulls out the bolt 14 and the convex block 15 from the rubber sleeve 16, and the staff member can then rotate the turntable 8.
