Technical Field

[0001] The utility model belongs to the technical field of rice fertilization, in particular to a multifunctional fertilization device for green rice planting. Background Art

[0002] Rice cultivation is of vital importance to agriculture and food security. Farmers ensure a good harvest through careful planting, irrigation and management.

[0003] For example, a Chinese patent with publication number CN210928616U discloses a rice fertilization device, including a bottom plate, a box body is arranged at the upper end of the bottom plate, a stirring rod is arranged inside the box body, a feed port is arranged at the upper end of the box body, a mounting seat is arranged on the right side of the outside of the box body, a motor is fixed on the mounting seat, a circulation pump is arranged on the left side of the outside of the box body, a support frame is fixed to the upper end of the bottom plate on the left side of the circulation pump, a cross frame is fixed to the upper end of the support frame, nozzles are fixed on both sides of the lower end of the cross frame, support columns are fixed on both sides of the lower end of the bottom plate, iron frames are fixed at the lower end positions of the support columns, mounting plates are arranged at the positions of the iron frames on the side corresponding to the iron frames, and U-shaped screws are arranged at the other end of the iron frames. The utility model solves the problems of unadjustable wheelbase and uneven fertilization in the rice fertilization device by arranging a stirring rod, a U-shaped screw and a mounting plate.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the device uses a U-shaped screw and a fixing nut when adjusting the distance between the connecting rods, and auxiliary tools are required for installation and fixing when using the U-shaped screw and the fixing nut, which is inconvenient. In addition, the rice is short when it is just planted, and it will gradually become taller after growing. The device is not convenient for adjusting the distance between the two nozzles and the rice. If the nozzle is far away from the rice, the effect of spraying fertilizer solution will be poor. In view of this, we propose a multifunctional fertilization device for green rice planting. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional fertilizing device for green rice planting to solve the problems raised in the above-mentioned background technology.

[0007] In view of this, the utility model provides a multifunctional fertilizing device for green rice planting, comprising:

[0008] A base, a connecting plate is fixedly installed on the top of the base, an electric push rod is symmetrically fixedly installed between the base and the connecting plate, and the output shaft of the electric push rod passes through the base and is fixedly installed with a rectangular plate, a limiting groove is symmetrically provided at the bottom of the base, and a bidirectional threaded rod is rotatably installed in the limiting groove, a slider is symmetrically threaded on the bidirectional threaded rod, and a roller is fixedly installed at the bottom of the slider;

[0009] A power assembly, which is located in the base and is used to drive the two bidirectional threaded rods to rotate;

[0010] A mixing box, wherein the mixing box is fixedly mounted on the top of the connecting plate, a fixing plate is fixedly mounted on the front side of the base, and a slide groove is provided on the fixing plate, a rectangular tube is slidably mounted in the slide groove, and a plurality of through grooves are provided on one side of the slide groove, a latch is provided in one of the through grooves, and one end of the latch extends into the rectangular tube, and two nozzles are fixedly mounted on the bottom of the rectangular tube;

[0011] A liquid supply component is located on the connecting plate and is used to transport the liquid medicine in the mixing box to the rectangular tube.

[0012] In the technical solution, when in use, when it is necessary to adjust the distance between the two sliders on the bidirectional threaded rod, the staff starts the two electric push rods, so that the output shafts of the two electric push rods respectively drive the two rectangular plates to move downward until the rectangular plates are in contact with the ground, and the output shafts of the electric push rods continue to extend, and then the base and the connecting plate will move upward, so that the two bidirectional threaded rods in the base will move upward, and then the two sliders on the bidirectional threaded rods will drive the corresponding rollers to move upward until the rollers are no longer in contact with the ground;

[0013] Then, the driving assembly is started to drive the two bidirectional threaded rods to rotate. Subsequently, under the action of the threads, the two sliders on the bidirectional threaded rods will approach each other, and the two sliders will drive the corresponding rollers to approach each other, so that the four rollers are adjusted to the appropriate positions and then the motor is turned off. The above operation can be reversed to make the two sliders on the bidirectional threaded rods move away from each other. This process does not require the use of fixing nuts and auxiliary tools, which is more convenient.

[0014] When it is necessary to adjust the height of the two nozzles from the ground, the staff will pull out the pin from one of the through slots and the rectangular tube. At this time, the rectangular tube will be released from the limit, and the rectangular tube can slide up and down at will in the slide slot. Subsequently, the rectangular tube can be moved upward in the slide slot so that the rectangular tube is moved to another through slot above one of the through slots. At this time, the rectangular tube will drive the two nozzles to move upward, and then one end of the pin is inserted into the other through slot, and one end of the pin is moved in the other through slot and inserted into the rectangular tube. At this time, the rectangular tube will be fixed in the position of the other through slot, and the height of the two nozzles from the rice will increase. The above operation can make the rectangular tube move downward in the slide slot, and then the position of the rectangular tube is fixed by the pin, so that the distance between the rectangular tube and the rice becomes smaller, ensuring that the rice at different heights at different stages can be better sprayed with fertilizer and medicine, and the spraying effect is better. The adjustment method is more convenient;

[0015] When fertilizing, the staff starts the liquid supply component to transport the fertilizer solution in the mixing box of the liquid supply component to the rectangular tube.

[0018] A cavity is provided in the base and is located on the other side of one of the limiting grooves. A motor is fixedly installed in the cavity. The output shaft of the motor passes through one side of the cavity and extends into one of the limiting grooves. The output shaft of the motor is coaxially connected with a bidirectional threaded rod in one of the limiting grooves.

[0019] In this technical solution, the motor is started so that the output shaft of the motor drives one of the two-way threaded rods to rotate slowly in the forward direction, and then one of the two-way threaded rods will drive one of the transmission wheels to rotate, and then one of the transmission wheels will drive the belt to transmit, and then the belt will drive another transmission wheel to rotate, and the other transmission wheel will drive another two-way threaded rod to rotate. Under the action of the thread, the two sliders on the two-way threaded rod will approach each other, and the two sliders will drive the corresponding rollers to approach each other, so that the four rollers are adjusted to the appropriate position and then the motor can be turned off.

[0020] In the above technical solution, further, one end of the transmission wheel is rotationally connected to the limiting groove, and the output shaft of the motor is rotationally connected to one of the limiting grooves and the cavity.

[0091] Working principle: When in use, when it is necessary to adjust the distance between the two sliders 19 on the bidirectional threaded rod 15, the staff starts the two electric push rods 12, so that the output shafts of the two electric push rods 12 respectively drive the two rectangular plates 10 to move downward until the rectangular plates 10 are in contact with the ground, and the output shafts of the electric push rods 12 continue to extend, and then the base 1 and the connecting plate 2 will move upward, so that the two bidirectional threaded rods 15 in the base 1 will move upward, and then the two sliders 19 on the bidirectional threaded rod 15 will drive the corresponding rollers 14 to move upward until the rollers 14 are no longer in contact with the ground;

[0092] Then, the staff starts the motor 20, so that the output shaft of the motor 20 drives one of the two-way threaded rods 15 to rotate slowly in the forward direction, and then, one of the two-way threaded rods 15 will drive one of the transmission wheels 18 to rotate, and then, one of the transmission wheels 18 will drive the belt 17 to transmit, and then, the belt 17 will drive another transmission wheel 18 to rotate, and the other transmission wheel 18 will drive another two-way threaded rod 15 to rotate.

The above operation can be reversed to make the two sliders 19 on the two-way threaded rod 15 move away from each other. This process does not require the use of fixing nuts and auxiliary tools, which is more convenient.

[0093] When it is necessary to adjust the height of the two nozzles 11 from the ground, the staff will pull out the latch 23 from one of the through slots 8 and the rectangular tube 7.

Then, the rectangular tube 7 can be moved upward in the slide slot 13, so that the rectangular tube 7 is moved to the other through slot 8 above one of the through slots 8. At this time, the rectangular tube 7 will drive the two nozzles 11 to move upward, and then one end of the latch 23 is inserted into the other through slot 8, and one end of the latch 23 is moved in the other through slot 8 and inserted into the rectangular tube 7. At this time, the rectangular tube 7 will be fixed at the position of the other through slot 8, and the height of the two nozzles 11 from the rice will increase. Through the above operation, the rectangular tube 7 can be moved downward in the slide slot 13, and then the position of the rectangular tube 7 is fixed by the latch 23, so that the distance between the rectangular tube 7 and the rice becomes smaller, ensuring that the rice at different heights at different stages can be better sprayed with fertilizer and medicine, and the spraying effect is better, and the adjustment method is more convenient;

[0094] When fertilizing the rice, the staff starts the water pump 5, and the water pump 5 will extract the fertilizer solution in the mixing box 3 through the connecting pipe 4. Then, the water pump 5 will transport the fertilizer solution to the hose 9. Then, the fertilizer solution in the hose 9 will enter the rectangular tube 7. The fertilizer solution in the rectangular tube 7 enters the two nozzles 11 under the action of water pressure and is sprayed out, thereby fertilizing the rice.
