Description

Technical Field

[0001] The invention relates to the technical field of fertilizing mustard greens at wheat stubble, and in particular to a fertilizing device and a fertilizing method for mustard greens at wheat stubble. Background Art

[0002] Wheat and mustard is a brand-new planting model. After wheat is harvested at the end of June, mustard is planted in early July and can be harvested at the end of September or early October. Then the land is prepared to plant winter wheat. Generally, 3,500 to 4,000 kg of mustard can be produced per mu, with good economic benefits. Therefore, the new planting model of mustard after wheat stubble is becoming more and more widely promoted.

[0003] After the wheat is harvested at the end of June, the stubble should be killed by rotary tillage in time (to facilitate the composting of the wheat stubble), the ground should be leveled and the soil should be finely divided to facilitate the emergence of the seedlings. Because the mustard seeds are small, if the soil clods are too large and the ground is uneven, the depth of the seeds covered with soil will be uneven, which may easily cause uneven emergence of seedlings, missing seedlings and broken ridges. The growth cycle of mustard is generally about 80 days, and fertilization should be mainly basal fertilizer. Secondly, in order to ensure better fertilization results, liquid fertilizer should be used for spraying under special conditions.

[0004] However, the existing technology has problems in the fertilization process. Since wheat stubble mustard is grown in large quantities in large fields in the north, the difference in plant spacing is very small. Traditional equipment is not convenient for fully automated quantitative spreading of solid fertilizers, which can easily cause uneven fertilizer distribution on a row of wheat stubble mustard. This can easily lead to excessive concentration of wheat stubble mustard with more fertilizer, while insufficient concentration of wheat stubble mustard with less fertilizer.

When the driving wheel 10 rotates, it controls the entire base plate 1 to move forward.

[0024] A conveying pipe 6 is fixedly provided on the outer wall of the solid box 5, and the unloading mechanism 2 includes a unloading pipe 201 fixedly provided at the output end of the conveying pipe 6, the outer wall of the driving rod 14 and the keyway on one side of the second gear 18 are connected with a first pulley 202, the outer wall of the unloading pipe 201 is rotatably connected with a second pulley 203, the outer walls of the first pulley 202 and the second pulley 203 are sleeved with a first belt 204, the inner wall of the unloading pipe 201 is fixedly provided with a limit plate 25, the inner part of the limit plate 25 is slidably connected with a rack 26, the inner part of the unloading pipe 201 and located at the axis of the second pulley 203 is fixedly provided with a half gear 28, the inner wall of the unloading pipe 201 and located below the half gear 28 is fixedly provided with a snap ring 29, the bottom of the snap ring 29 is rotatably connected with two baffles 210, the inner parts of the two baffles 210 are fixedly provided with a middle rod 211, and the bottom end of the rack 26 is rotatably connected with two connecting plates 212.

[0025] Combination Figure 4 and Figure 5 : When the driving rod 14 rotates, the rotating driving rod 14 drives the rotating first pulley 202 to control the transmission of the first belt 204 and thus drives the second pulley 203 to rotate; When the feeding mechanism 2 is in the initial state, the two baffles 210 are in a closed state inside the feeding pipe 201, so that the solid fertilizer in the feeding pipe 201 will not fall.

[0026] Combination Figure 6 : The rotation of the second pulley 203 drives the half gear 28 to rotate inside the discharge tube 201. When the half gear 28 rotates, it meshes and drives the rack 26 to move downward. When the rack 26 descends, it controls the two connecting plates 212 to descend. During the process of the connecting plates 212 descending, they will contact the two middle rods 211. Therefore, the middle rod 211 drives the two baffles 210 to make a circular turning motion along the hinge position of the clamp ring 29 to open. In this way, the solid fertilizer in the discharge tube 201 will fall on the ground of wheat stubble and mustard due to gravity; When the toothless surface of the half gear 28 rotates onto the rack 26 , the return spring 27 pulls the rack 26 to slide inside the limiting plate 25 and return to a closed state.

[0027] The first gear 17 and the second gear 18 are meshed with each other, the cone surface at the right end of the cone column 20 is tightly connected to the inside of the first gear 17 , and one end of the moving rod 23 extends to the inside of the notch 21 .

[0028] The half gear 28 is meshed with the rack 26 , the top end of the return spring 27 is fixedly connected to the lower surface of the limit plate 25 , and the bottom ends of the two connecting plates 212 are rotatably connected to the outer walls of the two middle rods 211 .

[0029] Understandable: Combined Figure 3 It can be seen that one end of the moving rod 23 is located inside the slot 21 . Therefore, when the motor 12 drives the key rod 13 to control the cone column 20 to rotate, the annular slot 21 will avoid the moving rod 23 , so the rotating cone column 20 will not interfere with the moving rod 23 .

[0030] This embodiment: This device is designed with an integrated linkage feeding mechanism 2 and a driving rod 14. When the driving rod 14 rotates, it can drive the driving wheel 10 to make the bottom plate 1 automatically move forward on the field of wheat stubble and mustard. Secondly, it will drive the half gear 28 through the first belt 204 to drive the rack 26 to make the baffle 210 open a mouth. In this way, when the bottom plate 1 moves forward, the feeding pipe 201 will quantitatively drop solid fertilizer on the field of wheat stubble and mustard. This design can make the fertilization amount more uniform and can effectively avoid the occurrence of uneven concentration of solid fertilizer.

[0031] Second embodiment: See also Figure 7 and Fig.10 , also includes a spraying mechanism 3 and an anti-sinking mechanism 4, the first mounting plate 15 is internally rotatably connected to a third gear 19, the outer wall of the solid box 5 is fixedly provided with a positioning plate 11, the internal rotatably connected to a rotating rod 31, the top of the rotating rod 31 is fixedly provided with a third pulley 32, the upper surface of the solid box 5 is rotatably connected to a fourth pulley 33, the outer walls of the third pulley 32 and the fourth pulley 33 are sleeved with a second belt 34, the top surface of the solid box 5 is installed with a fertilizer tank 35, the inner bottom of the fertilizer tank 35 is rotatably connected to a submersible pump 36, the top of the submersible pump 36 is installed with a nozzle 37, and a one-way valve 38 is installed inside the nozzle 37.

[0032] The bottom end of the rotating rod 31 is connected to the keyway at the axis of the fourth gear 24 , the third gear 19 and the fourth gear 24 are meshed with each other, and the bottom end of the submersible pump 36 is connected to the keyway at the axis of the fourth pulley 33 .

[0033] Combination Figure 7 : The user controls the electric cylinder 22 to push the moving rod 23 to move to the left, and the moving rod 23 will contact the notch 21 so that the left end cone surface of the cone column 20 and the third gear 19 are tightly connected, so that the right end cone surface of the cone column 20 is separated from the first gear 17; When the motor 12 is started, the key rod 13 is driven to control the third gear 19 to rotate. When the third gear 19 rotates, it engages and controls the fourth gear 24 to rotate. Therefore, in this case, the first gear 17 will not rotate. When the fourth gear 24 rotates, it will drive the rotating rod 31 to control the third pulley 32 to rotate. The third pulley 32 rotates to control the fourth pulley 33 to control the submersible pump 36 and the entire nozzle 37 to rotate. The submersible pump 36 can transport the liquid fertilizer in the fertilizer tank 35 to the nozzle 37. Finally, the nozzle 37 rotates to spray fertilizer on the leaves of the wheat stubble mustard.

[0034] The anti-sinking mechanism 4 includes a cam 41 fixedly mounted on the outer wall of the submersible pump 36, a mounting frame 42 is fixedly mounted above the solid box 5 and on one side of the fourth pulley 33, an air bag 44 is mounted inside the mounting frame 42, a spring pressure plate 43 is slidably connected to the outside of the mounting frame 42, a hose 45 is sealably mounted on the outer wall of the air bag 44, an annular tube 46 is mounted on the inner wall of the fertilizer tank 35, and nozzles 47 distributed in an annular pattern are sealably mounted on the outer wall of the annular tube 46.

[0035] One side of the spring pressure plate 43 is in contact with the outer wall of the air bag 44 , and the air outlet end of the hose 45 is sealed and installed with the outer wall of the ring tube 46 .

[0036] Combination Fig.10 When the fourth pulley 33 is in the process of continuous rotation, it will drive the cam 41 to rotate continuously. During the rotation of the cam 41, it will continuously resist the spring pressure plate 43 to reciprocate and repeatedly compress and expand the airbag 44 in the mounting frame 42. The annular tube 46 can be continuously inflated through the hose 45, so that the gas will rush out from multiple nozzles 47, and the outlet direction of the nozzle 47 is toward the inner bottom of the fertilizer tank 35, so that a high-pressure airflow will be formed inside the fertilizer tank 35.

[0037] In this embodiment, when solid fertilizer application is completed, the user can switch to the liquid fertilizer application state. By rotating the nozzle 37, not only can the device have the solid fertilizer application function, but also liquid spraying and fertilization can be performed, making its functions more diversified. Secondly, during the liquid fertilization process, the nozzle 37 can continuously spray high-pressure gas into the fertilizer tank 35, which can avoid the liquid fertilizer from sinking to the bottom and ensure that the liquid fertilizer is mixed more evenly.

[0038] Third embodiment: See also Fig.11 , further comprising a cleaning mechanism 8, the cleaning mechanism 8 comprising a water bag 81 fixedly mounted on the outer wall of the shield 7, the outer wall of the water bag 81 being respectively sealed with a water inlet pipe 82 and a water outlet pipe 83, and the top of the spray pipe 37 being rotatably connected with a fixed pipe 84; The bottom of the fixed pipe 84 is fixedly connected to the fertilizer tank 35 , and the water outlet end of the water outlet pipe 83 is sealed and installed with the fixed pipe 84 .

[0039] Combination Fig.11: When the user switches from the first embodiment to the second embodiment, the moving rod 23 moves from the right side to the left side, so the moving rod 23 will resist the force-controlled water bag 81 to perform a compression movement. When the water bag 81 is compressed, the water inside will be squeezed into the fixed pipe 84 through the water outlet pipe 83, and then enter the nozzle 37 through the fixed pipe 84, so that the inside of the nozzle 37 can be cleaned.

[0040] It can be understood that due to the provision of the one-way valve 38 , the cleaning water will only be sprayed out from the spray pipe 37 and will not flow into the fertilizer tank 35 .

[0041] In this embodiment: when the user switches from solid fertilization to liquid fertilization, the nozzle 37 can be cleaned by squeezing the water bag 81. This design is to prevent the residual medium inside the nozzle 37 from deteriorating and affecting the final fertilization effect. Therefore, this purpose achieves the cleaning effect and ensures that the fertilization effect can be optimized.

[0042] Please refer to Figures 1 to 11 The working principle of the fertilization device and fertilization method for wheat stubble mustard provided by the present invention is as follows: Step S1: First, the electric cylinder 22 pulls the moving rod 23 to control the cone column 20 to continuously move to the right side under force, so that the right cone surface of the cone column 20 continuously rubs against the inner cone surface of the first gear 17 under force. When the user starts the motor 12, the motor 12 will drive the key rod 13 to control the cone column 20 to rotate. At this time, the rotating cone column 20 will drive the first gear 17 to mesh with the second gear 18 to control the driving rod 14, so that the driving wheel 10 rotates. When the driving wheel 10 rotates, it controls the entire bottom plate 1 to move forward. When the driving rod 14 rotates, the rotating driving rod 14 will drive the rotating first pulley 202 to control the transmission of the first belt 204, thereby driving the second pulley 203 to rotate. When the feeding mechanism 2 is in the initial state, the two baffles 210 are in a closed state inside the feeding tube 201, so the solid fertilizer in the feeding tube 201 will not fall, and the rotation of the second pulley 203 will drive the half gear 28 to rotate inside the feeding tube 201. When the half gear 28 rotates, it will mesh and drive the rack 26 to move downward. When the rack 26 descends, it will control the two connecting plates 212 to descend. During the descent of the connecting plates 212, they will contact the two middle rods 211, driving the middle rods 211 to control the two baffles 210 to make a circular flipping motion along the hinge position of the clamping ring 29 to open, so that the solid fertilizer in the feeding tube 201 will fall on the ground of the wheat stubble and mustard due to gravity.

[0043] Step S2: The user controls the electric cylinder 22 to push the moving rod 23 to move to the left side. The moving rod 23 will resist the notch 21 so that the left end conical surface of the cone column 20 and the third gear 19 are tightly connected, so that the right end conical surface of the cone column 20 is separated from the first gear 17. When the motor 12 is started, it will drive the key rod 13 to control the third gear 19 to rotate. When the third gear 19 rotates, it will engage and control the fourth gear 24 to rotate. Therefore, in this case, the first gear 17 will not rotate. When the fourth gear 24 rotates, it will drive the rotating rod 31 to control the third pulley 32 to rotate. The third pulley 32 rotates to control the fourth pulley 33 to control the submersible pump 36 and the entire nozzle 37 to rotate. In this way, the submersible pump 36 can transport the liquid fertilizer in the fertilizer tank 35 to the nozzle 37. Finally, the nozzle 37 rotates to spray fertilizer on the leaves of wheat stubble mustard.

[0044] Step S3: The moving rod 23 moves from the right side to the left side, so the moving rod 23 will resist the force to control the water bag 81 to perform compression movement. When the water bag 81 is compressed, the water inside will be squeezed into the fixed pipe 84 through the water outlet pipe 83, and then enter the nozzle 37 through the fixed pipe 84, so that the inside of the nozzle 37 can be cleaned.

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.

9. A fertilization method for a fertilization device for mustard at wheat stubble, used for a fertilization device for mustard at wheat stubble as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: Fertilizer preparation method: first, the user needs to place the base plate on the field of wheat stubble and mustard to be fertilized, and then fill the solid fertilizer required in the solid box. Per mu, 2500-3000kg of decomposed farmyard manure, 25kg of superphosphate, 20kg of urea, and 10kg of potassium sulfate compound fertilizer should be applied in combination with land preparation; S2: Fertilization operation method, start the electric cylinder to pull the moving rod to control the cone column to continuously move to the right side to receive force, so that the right side cone surface of the cone column continuously rubs against the inner cone surface of the first gear to receive force; When the motor is started, the motor will drive the key rod to control the cone column to rotate. At this time, the rotating cone column will drive the first gear to mesh with the second gear to control the driving rod to make the driving wheel rotate. When the driving wheel rotates, it controls the entire bottom plate to move forward; When the driving rod rotates, the rotating driving rod will drive the rotating first pulley to control the first belt transmission and thus drive the second pulley to rotate. When the unloading mechanism is in the initial state, the two baffles are in a closed state inside the unloading tube, so the solid fertilizer in the unloading tube will not fall. The rotation of the second pulley will drive the half gear to rotate inside the unloading tube. When the half gear rotates, it will mesh and drive the rack to move downward. When the rack descends, it will control the two connecting plates to descend. During the process of the connecting plates descending, they will contact the two middle rods. Therefore, this will drive the middle rod to control the two baffles to make a circular flipping motion along the hinged position of the clamp ring to open, and the solid fertilizer in the unloading tube will fall on the ground of the wheat stubble and mustard due to gravity. S3: Leaf fertilization method, the user controls the electric cylinder to push the moving rod to the left, the moving rod will resist the notch so that the cone surface at the left end of the cone column and the third gear are tightly connected, so that the cone surface at the right end of the cone column is separated from the first gear, so that when the motor is started, it will drive the key rod to control the third gear to rotate, and when the third gear rotates, it will engage and control the fourth gear to rotate. Therefore, in this case, the first gear will not rotate, and when the fourth gear rotates, it will drive the rotating rod to control the third pulley to rotate, and the third pulley rotation transmission controls the fourth pulley to control the submersible pump and the entire nozzle to rotate, so that the submersible pump can transport the liquid fertilizer in the fertilizer tank to the nozzle, and finally the nozzle rotates to spray fertilizer on the leaves of wheat stubble mustard.
