[0003] Existing microbial fertilizer irrigation devices have difficulty controlling the irrigation volume, resulting in insufficient irrigation when the microbial fertilizer solution is too small, and insufficient absorption when the microbial fertilizer solution is too large, which affects crop growth. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a quantitative irrigation device for microbial fertilizer, which effectively solves the problem of difficulty in controlling the irrigation volume.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microbial fertilizer quantitative irrigation device, including an irrigation box, a base fixedly connected to the bottom of the irrigation box, multiple universal wheels provided at equal angles on the bottom of the base, a push rod fixedly connected to the top of the base, a drip irrigation pipe and a liquid inlet pipe fixedly connected to the outside of the irrigation box, and a quantitative mechanism provided on the irrigation box.

[0006] The metering mechanism includes a mounting ring fixed to the top of the irrigation tank. A U-shaped rod is fixedly connected to the top of the mounting ring. Two inner blocks are symmetrically and movably sleeved on the outer side of the U-shaped rod. A lifting ring is fixedly connected between the two inner blocks. A float plate is provided inside the irrigation tank. Two L-shaped rods are symmetrically and fixedly connected between the float plate and the lifting ring. Both L-shaped rods pass through the irrigation tank and are movably connected to it. An adjusting plate is movably sleeved on the outer side of the U-shaped rod. The adjusting plate is located below the two inner blocks. A mounting column is fixedly connected to the bottom of the adjusting plate. The bottom end of the mounting column extends into the interior of the irrigation tank and is equipped with a pressure sensor. The pressure sensor is located above the float plate.

[0007] Preferably, a controller is installed on the top of the irrigation tank, a control valve is provided on the inlet pipe, a pressure sensor is electrically connected to the controller, and the controller is electrically connected to the control valve.

[0008] Preferably, a sleeve plate is fixedly sleeved on the outer side of the U-shaped rod, and springs are fixedly connected between the top of the two inner blocks and the bottom of the sleeve plate, with both springs sleeved on the outer side of the U-shaped rod.

[0009] Preferably, a screw is rotatably connected to the top of the mounting ring, a drive shaft is fixedly connected to the top of the screw, a handwheel is fixedly connected to the top of the drive shaft, the drive shaft passes through the sleeve plate and is rotatably connected to the sleeve plate, and a threaded sleeve is threaded onto the outer side of the screw, and the threaded sleeve is fixed to the outer side of the adjusting plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figures 1-2 The present invention relates to a microbial fertilizer quantitative irrigation device, comprising an irrigation tank 1, a base 7 fixedly connected to the bottom of the irrigation tank 1, a plurality of universal wheels 8 provided at equal angles on the bottom of the base 7, a push rod 6 fixedly connected to the top of the base 7, a drip irrigation pipe 9 and an inlet pipe 4 fixedly connected to the outside of the irrigation tank 1, and a quantitative mechanism 2 provided on the irrigation tank 1.

[0024] Specifically, by Figure 3The metering mechanism 2 includes a mounting ring 201 fixed to the top of the irrigation tank 1. A U-shaped rod 206 is fixedly connected to the top of the mounting ring 201. Two inner blocks 204 are symmetrically and movably sleeved on the outer side of the U-shaped rod 206. A lifting ring 203 is fixedly connected between the two inner blocks 204. A float plate 2014 is provided inside the irrigation tank 1. Two L-shaped rods 2013 are symmetrically and fixedly connected between the float plate 2014 and the lifting ring 203. Both L-shaped rods 2013 pass through the irrigation tank 1 and are movably connected to it. An adjusting plate 202 is movably sleeved on the outer side of the U-shaped rod 206. The adjusting plate 202 is located below the two inner blocks 204. A mounting column 2012 is fixedly connected to the bottom of the adjusting plate 202. The bottom end of the mounting column 2012 extends into the interior of the irrigation tank 1 and is equipped with a pressure sensor 2015. 15 is located above the float 2014. The top of the irrigation tank 1 is equipped with a controller 3. The inlet pipe 4 is equipped with a control valve 5. The pressure sensor 2015 is electrically connected to the controller 3. The controller 3 is electrically connected to the control valve 5. The outer side of the U-shaped rod 206 is fixedly sleeved with a sleeve plate 207. The top of the two inner blocks 204 and the bottom of the sleeve plate 207 are both fixedly connected with springs 205. The two springs 205 are both sleeved on the outer side of the U-shaped rod 206. The top of the mounting ring 201 is rotatably connected with a screw 2010. The top of the screw 2010 is fixedly connected with a drive shaft 209. The top of the drive shaft 209 is fixedly connected with a handwheel 208. The drive shaft 209 passes through the sleeve plate 207 and is rotatably connected to the sleeve plate 207. The outer side of the screw 2010 is threaded with a screw sleeve 2011. The screw sleeve 2011 is fixed to the outer side of the adjusting plate 202.

[0025] In operation, first rotate the handwheel 208, which drives the drive shaft 209 to rotate, and in turn drives the screw 2010 to rotate. This, via the screw sleeve 2011, causes the adjusting plate 202 to slide along the U-shaped rod 206. Then, via the mounting column 2012, the pressure sensor 2015 moves. The height of the pressure sensor 2015 can be adjusted according to the required amount of microbial fertilizer solution. Next, open the control valve 5 to inject the microbial fertilizer solution into the irrigation tank 1 through the inlet pipe 4. When the water level in the irrigation tank 1 rises, it causes the float 2014 to move upwards. This, in turn, causes the lifting ring 203 to rise via the two L-shaped rods 2013, and... Both inner blocks 204 slide upward along the U-shaped rod 206, while both springs 205 are compressed. When the float 2014 contacts the pressure sensor 2015, the pressure sensor 2015 transmits an electrical signal to the controller 3. The controller 3 controls the control valve 5 to close, stopping the injection of bacterial fertilizer solution into the irrigation tank 1, thus completing the quantitative liquid addition to the irrigation tank 1 and finally achieving quantitative irrigation. When the water level in the irrigation tank 1 drops, the float 2014 moves downward under the elastic force of the two springs 205, making it easier for the float 2014 to reset and inject bacterial fertilizer solution again.

[0026] Specifically, byFigure 4 As shown, the inner side of the inner block 204 is provided with an annular groove 2016, and the inner side of the annular groove 2016 is provided with multiple balls 2017 that abut against the U-shaped round rod 206 at equal angles. The top of the irrigation tank 1 is provided with two through holes 10 symmetrically, and two L-shaped round rods 2013 pass through the two through holes 10 respectively. The outer diameter of the L-shaped round rod 2013 is greater than the inner diameter of the through hole 10.

[0027] In use, a through hole 10 is provided on the top of the irrigation tank 1 to facilitate the avoidance of the L-shaped rod 2013. When the inner block 204 slides on the outside of the U-shaped rod 206, it drives each ball 2017 to roll along the outer wall of the U-shaped rod 206, avoiding direct contact between the inner block 204 and the U-shaped rod 206, reducing the friction force on the inner block 204 when sliding on the outside of the U-shaped rod 206, and finally ensuring the stability of the float 2014 when it rises and falls.
