Fertilizing device and method for applying corn formula fertilizer

Abstract

The present invention relates to the field of fertilization technology, and discloses a fertilizing device and a method for applying a formula fertilizer to corn. By placing a guide wheel in a seed groove before operating the fertilizing device, the guide wheel is restricted by the seed groove and always moves within the seed groove when the fertilizing device moves on the field path. Furthermore, when the seed groove deviates, the guide wheel can drive the fertilizing wheel to move together via a slide plate, thereby maintaining a constant distance between the guide wheel and the fertilizing wheel. Specifically, the distance between the seed groove and the fertilizing position is maintained within 5-8 cm, thereby ensuring accurate fertilization in the field and improving the fertilization effect of the field.

Description

Technical Field

[0001] The present invention relates to the technical field of fertilization, in particular to a fertilization device and a method for fertilizing corn formula fertilizer. Background Art

[0002] Corn is an annual herbaceous plant in the genus Zea in the Poaceae family. As a monoecious, cross-pollinated annual plant, corn boasts tall, strong stems and is an important food and feed crop. It is also the most productive crop worldwide, with its cultivated area and total yield second only to rice and wheat. Regular fertilization is necessary to maintain corn growth, and this is accomplished using a fertilization device.

[0003] As described in Chinese patent application CN110383979A, organic fertilizer is placed in a feed box. When the telescopic assembly drives the feed box to enter the upper portion of the feed port of a silo equipped with a crushing rod, the organic fertilizer in the feed box falls into the corresponding silo and is crushed by the crushing rod. Inorganic fertilizer is placed in another silo, and the organic fertilizer and inorganic fertilizer in the two silos leak out of the corresponding discharge ports, and are transported to the discharge ports by a discharge device. Multiple discharge devices are spaced apart along the second horizontal direction, corresponding to the row spacing of corn, and then the organic and inorganic fertilizers are applied simultaneously as the bracket moves. Therefore, this device solves the problem of the fertilization device being unable to apply organic and inorganic fertilizers simultaneously during the summer corn sowing process.

[0004] However, there are still the following problems: when applying oral fertilizer, it is generally required that the distance between the oral fertilizer and the seeds is 5-8 cm. Only within this range can the fertilization effect be guaranteed.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0038] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a fertilizing device and a method for fertilizing corn formula fertilizer.

[0039] In a typical embodiment of the present application, Figure 1 As shown, a fertilizing device includes a body 1, a fertilizing mechanism 2 provided on the body 1, and an auxiliary mechanism 3 provided on the fertilizing mechanism 2. The fertilizing mechanism 2 includes a fertilizing wheel 29 provided on the body 1, and the fertilizing wheel 29 applies fertilizer to seeds.

[0040] The auxiliary mechanism 3 includes a slide plate 34 and a guide wheel 39. The slide plate 34 is slidably arranged on the body 1. One end of the slide plate 34 is connected to the fertilizer wheel 29. When the slide plate 34 moves, it drives the fertilizer wheel 29 to move. The guide wheel 39 is arranged on the other end of the slide plate 34.

[0041] The guide wheel 39 is placed in the seed groove. When the seed groove is deviated, the guide wheel 39 drives the slide plate 34 to move laterally.

[0042] When using the present invention:

[0043] Move the fertilizing device to the field road between the seed grooves, place the guide wheel 39 in the seed groove, start the fertilizing device, and manually push the fertilizing device to move on the field road. The guide wheel 39 moves in the seed groove. The fertilizing wheel 29 fertilizes the seed grooves in turn as the fertilizing device moves. When the seed groove deviates, the limiting force of the seed groove wall causes the guide wheel 39 to move, so that the guide wheel 39 always keeps moving in the seed groove. At the same time, the guide wheel 39 drives the slide plate 34 to move, and the slide plate 34 drives the fertilizing wheel 29 to move, so that the distance between the fertilizing wheel 29 and the guide wheel 39 always remains unchanged.

[0044] By first placing the guide wheel 39 in the seed groove and then operating the fertilizing device, when the fertilizing device moves on the field road, it is restricted by the seed groove and the guide wheel 39 always keeps moving inside it. When the seed groove deviates, the guide wheel 39 can drive the fertilizing wheel 29 to move together through the slide plate 34, thereby keeping the distance between the guide wheel 39 and the fertilizing wheel 29 unchanged, that is, ensuring that the distance between the seed groove and the fertilizing position is maintained within 5-8 cm, ensuring the accuracy of fertilizing in the oral fertilizer and improving the effect of oral fertilizer fertilization.

[0045] Furthermore, the fertilizing wheel 29 is a device for semi-automatically fertilizing seeds in the prior art, such as Chinese patent CN105493723B.

[0046] Further, such as Figure 1-Figure 3 As shown, the fertilizing mechanism 2 further includes a plurality of storage boxes 21, which are loaded with fertilizer. The storage boxes 21 are fixedly mounted on the machine body 1 and are symmetrically distributed. A plurality of controlled quantity feeders 22 are fixedly mounted on the machine body 1. Control valves 23 are fixedly mounted at the bottom ends of the storage boxes 21. The control valves 23 on both sides are respectively connected to the storage boxes 21 on both sides. A through pipe 24 is provided between the control valve 23 and the control feeder 22. One end of the through pipe 24 is connected to the control feeder 22, and the other end of the through pipe 24 is connected to the control valve 23.

[0047] Furthermore, the fertilizer is existing technology, specifically including one of the existing technology formula fertilizer, compound fertilizer, potash fertilizer, phosphate fertilizer, and nitrogen fertilizer, such as the existing technology corn formula fertilizer.

[0048] Specifically, the controlled quantity feeder 22 may use a ball screw for feeding, and the ball screw rotates inside the controlled quantity feeder 22 to generate a pushing force to push the fertilizer into the fertilizer wheel 29 .

[0049] Among them, the fertilizer is first stored in the storage box 21, the control valve 23 is manipulated to control the displacement of the fertilizer when it is discharged from the storage box 21, and the control feeder 22 is started. The control feeder 22 generates a pushing force to draw the fertilizer discharged from the control valve 23 in the storage box 21 into the control feeder 22 through the through pipe 24.

[0050] Further, such as Figure 2-Figure 4 As shown, a feeding pipe 25 is provided on the controlled quantity feeder 22, one end of the feeding pipe 25 is communicated with the controlled quantity feeder 22, and an auxiliary telescopic tube 26 is fixedly installed on the other end of the feeding pipe 25, the auxiliary telescopic tube 26 is communicated with the feeding pipe 25, and a bearing 27 is fixedly installed on the extension tube of the auxiliary telescopic tube 26, the inner ring of the bearing 27 is connected to the auxiliary telescopic tube 26, and a pulley 28 is fixedly installed on the outer ring of the bearing 27, and the extension tube of the auxiliary telescopic tube 26 passes through the pulley 28, the auxiliary telescopic tubes 26 on both sides are respectively communicated with the fertilizer wheels 29 on both sides, and a plurality of fertilizer ports are opened on the fertilizer wheel 29, and the fertilizer ports of the fertilizer wheel 29 are evenly distributed on the fertilizer wheel 29, and a shovel 210 is fixedly installed between the fertilizer ports of the fertilizer wheel 29.

[0051] The fertilizer is pushed from the control feeder 22 into the feed pipe 25 by the pushing force of the control feeder 22 , and then the fertilizer slides from the feed pipe 25 into the auxiliary telescopic tube 26 , and then falls from the auxiliary telescopic tube 26 into the fertilizing wheel 29 .

[0052] Further, such as Figure 3-Figure 5 As shown, a support frame 211 is fixedly installed on the body 1, a positioning frame 212 is provided on the support frame 211, and connecting plates 213 are provided on both sides of the positioning frame 212. The connecting plates 213 on both sides are respectively rotated and matched with the fertilizer wheels 29 on both sides. The connecting plates 213 are fixedly connected to one end of the slide plate 34, and the connecting plates 213 are symmetrically distributed.

[0053] Further, such as Figure 2-Figure 3 As shown, a dual-axis motor 214 is fixedly mounted on the machine body 1, and belts 215 are tensioned on both side shafts of the dual-axis motor 214 and the pulleys 28 on both sides. A handle 216 is fixedly mounted on the machine body 1, and a backfill baffle 217 is fixedly mounted on the bottom end of the machine body 1. The backfill baffle 217 is used to backfill the soil produced by fertilization.

[0054] Among them, the dual-axis motor 214 is started, the dual-axis motor 214 drives the belt 215 to rotate, the belt 215 drives the pulley 28 to rotate, and the pulley 28 drives the fertilizer wheel 29 to rotate, so that the shovel 210 on the fertilizer wheel 29 shovels soil to shovel out the fertilizer pit, and as the fertilizer wheel 29 rotates, the fertilizer in the fertilizer wheel 29 falls out from the fertilizer port closest to the downward vertical direction due to its own gravity, so that the fertilizer falls into the fertilizer pit, and the connection between the pulley 28 and the auxiliary telescopic tube 26 through the bearing 27 ensures stable rotation.

[0055] Further, such as Figure 1 、 Figure 5 、 Figure 6As shown, the auxiliary mechanism 3 also includes a plurality of limit members 31, and the plurality of limit members 31 are symmetrically fixedly installed on both sides of the support frame 211. The positioning frame 212 slides with the limit members 31. The limit members 31 are all rotatably fitted with positioning knobs 32, and the positioning knobs 32 pass through the wall of the limit members 31. The positioning knobs 32 are used to limit the sliding of the positioning frame 212. The bottom end of the positioning frame 212 is fixedly installed with a slide rail 33, and the slide rail 33 slides with the slide plate 34.

[0056] Preferably, the length of the feeding tube 25 can be changed to adapt to the length between the controlled quantity feeder 22 and the auxiliary telescopic tube 26 .

[0057] Among them, loosening the positioning knob 32 can make the positioning frame 212 slide on the limit member 31 to adjust the relative position of the positioning frame 212 and the support frame 211, and tightening the positioning knob 32 again to drive the slide rail 33 to move, the slide rail 33 drives the slide plate 34 to move, and the slide plate 34 drives the fertilizer wheel 29 to move, so that it controls the height of the fertilizer wheel 29, so that the fertilizer wheel 29 and the shovel 210 can better control the depth of the fertilizer pit shoveled out, thereby improving the quality of fertilization.

[0058] Further, such as Figure 5-Figure 7 As shown, the other end of the slide 34 is rotatably fitted with a telescopic rod 35, and the fixed rod of the telescopic rod 35 is rotatably fitted with the slide 34. The other end of the slide 34 is rotatably fitted with an upper arm 36, and the upper arm 36 is arranged next to the telescopic rod 35. The extension rod of the telescopic rod 35 is rotatably fitted with a lower arm 37, and the lower arm 37 is rotatably fitted with the upper arm 36. The connecting shaft between the upper arm 36 and the slide 34 is sleeved with a torsion spring 38, one end of the torsion spring 38 is connected to the upper arm 36, and the other end of the torsion spring 38 is connected to the slide 34. The extension rod of the telescopic rod 35 is provided with a guide wheel 39, and the bottom end of the positioning frame 212 is slidably fitted with a fixing part 310, and the fixing part 310 passes through the wall of the positioning frame 212, and the fixing part 310 is located next to the upper arm 36. The fixing part 310 is used to limit the rotation of the upper arm 36.

[0059] Further, if Figure 6 As shown, the initial state of the telescopic rod 35, the upper arm 36, and the lower arm 37 is the state shown in the figure.

[0060] The extension rod 35 of the telescopic rod 35 is extended downwardly with the elasticity provided by the torsion spring 38 and the gravity of the extension rod 35. At the same time, the angle between the upper arm 36 and the lower arm 37 continues to expand, so that the extension rod of the telescopic rod 35 drives the guide wheel 39 downward to stabilize the guide wheel 39 in the seed groove and prevent the guide wheel 39 from deviating from the seed groove. When the guide wheel 39 is not needed during the non-fertilization period, the telescopic rod 35 is manually rotated to cause the upper arm 36 and the lower arm 37 to shrink and retract for operation. When the upper arm 36 is moved as a whole to be higher than the fixing part 310, the fixing part 310 is extended and inserted between the upper arm 36 and the lower arm 37 to limit the rotation of the upper arm 36 and the lower arm 37, thereby retracting the telescopic rod 35, the upper arm 36, and the lower arm 37 and no longer using them. When they are used again, the fixing part 310 is retracted and the elastic restoring force of the torsion spring 38 restores the telescopic rod 35, the upper arm 36, and the lower arm 37 to their initial state, thereby increasing the use of the fertilizer device and improving the diversity of use of the fertilizer device.

[0061] The fertilizing wheel 29 is moved by the guide wheel 39 and the fertilizing wheel 29 is moved.

[0062] Further, such as Figure 8-9 As shown, a water tank 41 is fixedly installed on the support frame 211, and a plurality of water valves 42 are fixedly installed at the bottom of the water tank 41. The water valves 42 are symmetrically distributed and communicate with the inside of the water tank 41. Sprinkler heads 43 are fixedly installed on the water valves 42, and the sprinkler heads 43 are communicated with the water valves 42.

[0063] Working principle:

[0064] Move the fertilizing device to the field road between the seed grooves, place the guide wheel 39 in the seed groove, start the fertilizing device, and manually push the fertilizing device to move on the field road. The guide wheel 39 moves in the seed groove, and the fertilizing wheel 29 fertilizes beside the seed groove in turn as the fertilizing device moves. When the seed groove deviates, the limiting force of the seed groove wall causes the guide wheel 39 to move, so that the guide wheel 39 always keeps moving in the seed groove. At the same time, the guide wheel 39 drives the slide plate 34 to move, and the slide plate 34 drives the fertilizing wheel 29 to move, so that the fertilizing wheel 29 and the seed groove are aligned. The distance between the guide wheels 39 always remains unchanged. By first placing the guide wheels 39 in the seed groove and then operating the fertilizing device, when the fertilizing device moves on the field road, it is restricted by the seed groove and the guide wheels 39 always keep moving inside it. When the seed groove deviates, the guide wheels 39 can drive the fertilizing wheel 29 to move together through the slide 34, thereby keeping the distance between the guide wheels 39 and the fertilizing wheel 29 unchanged, that is, ensuring that the distance between the seed groove and the fertilizing position is maintained within 5-8 cm, ensuring the accuracy of fertilizing in the field and improving the effect of fertilizing in the field.

[0065] Among them, the fertilizer is first stored in the storage box 21, the control valve 23 is manipulated to control the displacement of the fertilizer when it is discharged from the storage box 21, and the control feeder 22 is started. The control feeder 22 generates a pushing force to draw the fertilizer discharged from the control valve 23 in the storage box 21 into the control feeder 22 through the through pipe 24. With the pushing force of the control feeder 22, the fertilizer is pushed from the control feeder 22 into the feeding pipe 25, and the fertilizer slides from the feeding pipe 25 to the auxiliary telescopic pipe 26, and then the fertilizer falls out of the auxiliary telescopic pipe 26. The fertilizer is fed into the fertilizer wheel 29. At the same time, the dual-axis motor 214 is started, and the dual-axis motor 214 drives the belt 215 to rotate. The belt 215 drives the pulley 28 to rotate. The pulley 28 drives the fertilizer wheel 29 to rotate, so that the shovel 210 on the fertilizer wheel 29 shovels soil to shovel out the fertilizer pit. As the fertilizer wheel 29 rotates, the fertilizer in the fertilizer wheel 29 falls out from the fertilizer port closest to the downward vertical direction due to its own gravity, so that the fertilizer falls into the fertilizer pit. The connection between the pulley 28 and the auxiliary telescopic tube 26 through the bearing 27 ensures stable rotation.

[0066] Furthermore, the positioning knob 32 can be loosened to allow the positioning frame 212 to slide on the limiting member 31 to adjust the relative position of the positioning frame 212 and the support frame 211, and the positioning knob 32 can be tightened again to drive the slide rail 33 to move, the slide rail 33 drives the slide plate 34 to move, and the slide plate 34 drives the fertilizer wheel 29 to move, so as to control the height of the fertilizer wheel 29, so that the fertilizer wheel 29 and the shovel 210 can better control the depth of the fertilizer pit shoveled out, thereby improving the quality of fertilization;

[0067] The extension rod 35 of the telescopic rod 35 is extended downwardly with the elasticity provided by the torsion spring 38 and the gravity of the extension rod 35. At the same time, the angle between the upper arm 36 and the lower arm 37 continues to expand, so that the extension rod of the telescopic rod 35 drives the guide wheel 39 downwardly to stabilize the guide wheel 39 in the seed groove and prevent the guide wheel 39 from deviating from the seed groove. When the guide wheel 39 is not needed during the non-fertilization period, the telescopic rod 35 is manually rotated to cause the upper arm 36 and the lower arm 37 to shrink and retract for operation. When the upper arm 36 is moved as a whole to be higher than the fixing member 310, the fixing member 310 is extended, and the fixing member 310 is extended between the upper arm 36 and the lower arm 37 to limit the rotation of the upper arm 36 and the lower arm 37, thereby retracting the telescopic rod 35, the upper arm 36, and the lower arm 37 and no longer using them. When they are used again, the fixing member 310 is retracted, and the elastic restoring force of the torsion spring 38 restores the telescopic rod 35, the upper arm 36, and the lower arm 37 to their initial state, thereby increasing the use of the fertilizer device and improving the diversity of use of the fertilizer device.

[0068] When the seed groove deviates, the guide wheel 39 is subject to the limiting force of the seed groove wall and the holding force provided by the spring 38, upper arm 36 and lower arm 37 to the telescopic rod 35, so that the guide wheel 39 remains to move in the seed groove, thereby causing the guide wheel 39 to drive the telescopic rod 35 to move, and the telescopic rod 35 drives the slide plate 34 to move on the slide rail 33, the slide plate 34 drives the connecting plate 213 to move, and the connecting plate 213 drives the fertilizing wheel 29 to move, thereby maintaining the distance between the guide wheel 39 and the fertilizing wheel 29, that is, ensuring that the distance between the seed groove and the fertilizer pit is maintained within 5-8 cm, effectively solving the problem that when applying oral fertilizer, the distance between the oral fertilizer and the seed is generally required to be 5-8 cm, and the fertilizing effect can be guaranteed within this range, but the existing device cannot ensure good control of the time interval of oral fertilizer, resulting in the phenomenon of burning seedlings and seeds when the spacing is too close, and the problem of poor fertilizing effect caused by too far spacing, thereby improving the fertilizing quality during oral fertilizer application.

[0069] The present invention also discloses a method for applying formula fertilizer to corn using the above-mentioned fertilizing device, comprising the following steps:

[0070] S1: Add corn formula fertilizer into the storage box 21 and add water into the water tank 41;

[0071] S2: First, move the fertilizing device to the field road between the seed grooves and place the guide wheel 39 in the seed grooves;

[0072] S3: Start the dual-axis motor 214 and push the fertilizing device to move on the field road, so that the fertilizing device shovels out the fertilizer pit through the shovel 210, and applies the corn formula fertilizer in the storage box 21 into the fertilizer pit through the fertilizer wheel 29;
