Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a portable parallel multi-channel synchronous fertilizer injection device. Background Art

[0002] Fertilization refers to the agricultural technical measure of applying fertilizers to the soil or spraying them on plants to provide the nutrients required by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, fertilize the soil, and improve economic efficiency. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain the sustainable development of agriculture.

[0003] With the development of modern precision agriculture, fluid fertilizers are mostly used for precise and rapid fertilization to meet agricultural needs. However, the current fertilizer injection devices generally can only perform single-channel fertilization, so the fertilization efficiency cannot be improved.

[0004] At the same time, although there are multi-channel fertilizer injection devices, due to the multi-channels, it is not convenient to control the fertilizer injection flow more conveniently. At present, the size of the fertilizer injection flow is mostly controlled manually, and the control effect is relatively single, cumbersome and not intelligent enough. When facing different crops, it is impossible to adjust the fertilizer injection flow size according to different crops respectively, resulting in insufficient or excessive fertilizer injection amount, affecting the fertilizer injection efficiency of crops and causing waste of fertilizers.

[0005] Furthermore, when the fertilizer spraying flow of the existing fertilizer injection device is adjusted, its nozzles cannot be better adapted, resulting in its inability to adjust the spraying range according to the sowing density of different crops, reducing the fertilizer injection effect of the fertilized crops, and thus the fertilizers cannot be effectively utilized. Summary of the Invention

[0022] 3.

[0023] 4. Through the cooperation of the nozzle component and the adjustment component, the nozzle component can change the spraying range of the nozzle component according to the size of the fertilizer injection flow rate. When the fertilizer injection flow rate is the largest, the spraying range of the nozzle component is also the largest. When the fertilizer injection flow rate becomes smaller, the spraying range of the nozzle component also shrinks accordingly, so as to adapt to different spraying ranges according to the planting density of crops, thereby improving the fertilizer injection efficiency of crops and making the injected fertilizer effectively utilized.

Detailed implementation manners

[0038] Refer to Figures 1-13 , a portable parallel multi-channel synchronous fertilizer injection device, including a body 1, a handrail 12 is fixedly connected to the side wall of the body 1, and a hook is fixedly connected to the handrail 12. The handrail 12 facilitates the user to push the device by hand, and at the same time, the hook on the handrail 12 can cooperate with other agricultural machinery to tow the device, so as to facilitate use. A fertilizer tank is installed in the body 1. A connecting frame 10 is fixedly installed on the body 1. A group of nozzle assemblies 5 are installed on the lower side of the connecting frame 10. As shown in the appendix, the number of the nozzle assemblies 5 can be 4, 6 or other numbers, and they are arranged horizontally, and can be determined according to the size of the field to be fertilized. A main pipe body 4 is also installed on the body 1, and the main pipe body 4 is communicated with the fertilizer tank. A group of pipelines 13 communicated with the nozzle assemblies 5 are fixedly installed in the connecting frame 10, and the main pipe body 4 is communicated with the corresponding pipelines 13 through shunt branch pipes 3. A pump body 2 for pumping the fertilizer in the fertilizer tank into the main pipe body 4 is also fixedly installed on the body 1. A plurality of universal wheels 11 are fixedly installed at the bottom of the body 1, and the universal wheels 11 facilitate the movement of the device; Figures 1-2 As shown in the appendix, the number of the nozzle assemblies 5 can be 4, 6 or other numbers, and they are arranged horizontally, and can be determined according to the size of the field to be fertilized. A main pipe body 4 is also installed on the body 1, and the main pipe body 4 is communicated with the fertilizer tank. A group of pipelines 13 communicated with the nozzle assemblies 5 are fixedly installed in the connecting frame 10, and the main pipe body 4 is communicated with the corresponding pipelines 13 through shunt branch pipes 3. A pump body 2 for pumping the fertilizer in the fertilizer tank into the main pipe body 4 is also fixedly installed on the body 1. A plurality of universal wheels 11 are fixedly installed at the bottom of the body 1, and the universal wheels 11 facilitate the movement of the device;

[0039] As Figures 1-2As shown, the fertilizer to be injected is placed in the fertilizer box. By starting the pump body 2, the fertilizer is pumped into the main pipe body 4, and then the fertilizer is respectively branched into multiple pipelines 13 by multiple shunt branch pipes 3. The fertilizer injection operation is completed by the nozzle assembly 5 below the pipeline 13, so as to realize the synchronous fertilizer injection operation of multiple channels. The above technical means are prior art, and the principles of the involved pump body 2 are all well-known technologies, so no more details will be described;

[0040] An adjustment assembly 6 for adjusting the fertilizer injection flow rate is installed on the machine body 1;

[0041] The adjustment assembly 6 includes: a motor 601, a first bevel gear 602, a second bevel gear 603, a first rotating shaft 604, a third bevel gear 605, a fourth bevel gear 606, a threaded drum 607, a screw rod 608, a sealing head 609, a sealing member 610, and a second rotating shaft 611. The motor 601 is fixedly installed on the machine body 1, and the output shaft of the motor 601 is fixedly connected to the first rotating shaft 604. A set of first bevel gears 602 is fixedly sleeved on the first rotating shaft 604. The number of the first bevel gears 602 is correspondingly set according to the number of the nozzle assemblies 5. A plurality of second rotating shafts 611 corresponding to the number of the first rotating shafts 604 are also rotatably connected in the machine body 1, and the upper ends of the second rotating shafts 611 are rotatably connected to second bevel gears 603 corresponding to the first bevel gears 602. A clamping assembly 9 is also installed between the second rotating shafts 611 and the second bevel gears 603;

[0042] The clamping assembly 9 includes a chuck 91 and a clamping head 92. A chuck 91 is slidably connected to each second rotating shaft 611, and a plurality of clamping heads 92 are fixedly connected to the upper side wall of the chuck 91. A clamping groove matching the clamping head 92 is opened on the lower side wall of the second bevel gear 603;

[0043] As Figure 13 shown, the sliding mode of the chuck 91 and the second rotating shaft 611 adopts the sliding fitting of a slider and a sliding groove, and is a vertical sliding connection. The cooperation of the slider and the sliding groove can not only act as a sliding part but also act as a limiting part. That is, when the second rotating shaft 611 rotates, it can drive the chuck 91 to rotate. In this solution, the connection mode between the second bevel gear 603 and the second rotating shaft 611 is a rotating connection. When the chuck 91 is slid so that the clamping head 92 on the chuck 91 is engaged with the clamping groove on the second bevel gear 603, when the first bevel gear 602 drives the second bevel gear 603 to rotate, the second bevel gear 603 can drive the chuck 91 to rotate, and the second rotating shaft 611 can be driven to rotate under the cooperation of the slider and the sliding groove. Therefore, whether the first rotating shaft 604 drives the second rotating shaft 611 to rotate through the cooperation of the first bevel gear 602 and the second bevel gear 603 is controllable;

[0044] The bevel gear one 602 meshes with the bevel gear two 603. A seal 610 is fixedly installed on each pipeline 13. A bevel gear three 605 is fixedly sleeved on the rotating shaft two 611. A threaded rotating cylinder 607 is rotatably connected to the pipeline 13. A bevel gear four 606 is fixedly connected to the outer side of the threaded rotating cylinder 607. The bevel gear three 605 is meshed and connected with the bevel gear four 606. A screw rod 608 is in threaded connection with the threaded rotating cylinder 607. The screw rod 608 is slidably connected to the pipeline 13. The end of the screw rod 608 is fixedly connected to a sealing head 609. The sealing head 609 is slidably connected in the pipeline 13 and is matched with the seal 610.

[0045] The sealing head 609 is round-headed. A rubber sealing pad is wrapped around the outer side of the sealing head 609. An arc-shaped groove matched with the sealing head 609 is opened at one end of the seal 610 close to the sealing head 609. A sealing pad is fixedly connected to the groove wall of the arc-shaped groove.

[0046] As Figures 3-5 shown, when the sealing head 609 is completely fitted with the seal 610, the pipeline 13 is in a closed state. That is, when the sealing head 609 gradually moves to the right, the flow rate of the pipeline 13 will gradually decrease. This structure is similar to a valve structure. Therefore, there is no need to make too much elaboration. The special-shaped sealing head 609 and the seal 610, together with the sealing pad, can achieve the sealing performance when the pipeline 13 is blocked. Combining with Figure 5 shown, after the upper clamping assembly 9 is adjusted and clamped, the rotating shaft one 604 can drive the rotating shaft two 611 to rotate through the mechanical transmission of the bevel gear one 602 and the bevel gear two 603, and then drive the threaded rotating cylinder 607 to rotate through the mechanical transmission of the bevel gear three 605 and the bevel gear four 606. Since the screw rod 608 is slidably arranged in the pipeline 13 and the internal thread of the screw rod 608 is in the threaded rotating cylinder 607, it can be known that when the screw rod 608 slides horizontally, its rotation can be limited. Therefore, the screw rod 608 can move horizontally, thereby completing the adjustment of the flow rate of the pipeline 13.

[0047] A control assembly 7 for controlling the clamping assembly 9 is also installed on the machine body 1.

[0048] The structure of the control assembly 7 refers to the attached Figures 10-13 shown. Its function is to control whether the clamping assembly 9 is clamped and to control the diversity of the adjustment of the upper adjustment assembly 6. For example, whether the adjustment assembly 6 adjusts the flow rates of multiple nozzle assemblies 5 at the same time and once, or selectively adjusts the flow rates of one or more nozzle assemblies 5, so that the fertilizer injection device can have multiple choices according to different crops planted in the fields, with wide applicability and simple adjustment.

[0049] The control component 7 includes: a control panel 701, a sliding plate 702, a rotary knob 703, a third rotating shaft 704, a second gear 705, a rack 706, a fixing plate 707, a mounting block 708, a connecting rod 709, a pressing rod 710, a sliding rod 711, a snap ring 712, and a groove 713. The control panel 701 is fixedly installed on the side wall of the machine body 1, and the sliding plate 702 is slidably connected within the machine body 1. The rotary knob 703 is rotatably connected to the control panel 701, and the rotary knob 703 is fixedly connected to the third rotating shaft 704. The third rotating shaft 704 penetrates through the control panel 701 and the side wall of the machine body 1 and is rotatably connected to the side wall of the machine body 1. The second gear 705 is fixedly sleeved on the third rotating shaft 704, and the rack 706 matching the second gear 705 is fixedly connected to the side wall of the sliding plate 702. A plurality of installation cavities are formed in the sliding plate 702, and the chuck 91 is placed within the installation cavities, and the chuck 91 does not contact the installation cavities. A plurality of fixing plates 707 are also fixedly connected within the machine body 1, and the mounting blocks 708 are slidably connected to the fixing plates 707. The number of the fixing plates 707 is also correspondingly set according to the number of the nozzle assemblies 5. The side wall of each mounting block 708 is fixedly connected to a connecting rod 709, and the connecting rod 709 slidably penetrates through the control panel 701 and is fixedly connected to a pressing rod 710. A pull ring is also installed on the pressing rod 710, which is convenient for pulling and also for pressing, so as to facilitate controlling the sliding of the mounting block 708 on the fixing plate 707. A sliding opening is formed in the mounting block 708, and a sliding rod 711 is slidably connected within the sliding opening. The sliding rod 711 slidably penetrates through the sliding plate 702 and extends into the installation cavity. The sliding mode of the sliding rod 711 with respect to the sliding plate 702 is forward and backward movement, and the sliding mode of the sliding rod 711 within the sliding opening is up and down sliding. The end of the sliding rod 711 is fixedly connected to a snap ring 712, and a groove 713 matching the snap ring 712 is formed in the side wall of the chuck 91. Figure 13 The structure of the snap ring 712 is shown as arc-shaped, and the groove 713 is annular, and the radian size of the snap ring 712 is consistent with the radian of the same area of the groove 713;

[0050] In the initial state of this solution, all the clamping components 9 have completed the clamping work between the second bevel gear 603 and the second rotating shaft 611. That is, when the motor 601 is turned on, under the drive of the motor 601, the flow rates of multiple pipelines 13 can be adjusted simultaneously, and the adjustment range is uniform. At the same time, the snap ring 712 is also embedded in the slot 713. When it is necessary to close the adjustment or selectively control the adjustment of a certain sprinkler component 5 or multiple sprinkler components 5, first rotate the knob 703 to drive the third rotating shaft 704 to rotate, thereby driving the second gear 705 to rotate. Under the action of the rack 706, the sliding plate 702 can be driven to move downward. Since the snap ring 712 is embedded in the slot 713 at this time, and the slide bar 711 fixedly connected to the snap ring 712 slides back and forth with the sliding plate 702, when the sliding plate 702 slides up and down, the snap ring 712 can be driven to slide up and down, thereby driving the chuck 91 to move downward through the snap ring 712. Therefore, the chuck 92 can be separated from the card slot of the second bevel gear 603, so that the clamping component 9 loses the clamping effect. The second bevel gear 603 and the second rotating shaft 611 are rotationally connected and not restricted by any means. Therefore, the first rotating shaft 604 cannot drive the second rotating shaft 611 to rotate through the first bevel gear 602 and the second bevel gear 603, and thus cannot adjust the flow rate of the pipeline 13. When I selectively control the flow rate of a certain sprinkler component 5 or multiple sprinkler components 5, I can first pull a certain pressing rod 710 or multiple pressing rods 710. Whichever is pulled, the flow rate adjustment operation of the corresponding sprinkler component 5 will not be closed. The explanation is as follows: Refer to the appendix Figure 12 and 13 , the pressing rod 710 is fixedly connected to the mounting block 708 through the connecting rod 709. In the initial state, the snap ring 712 and the slot 713 are in an embedded state. When the pressing rod 710 is pulled to drive the mounting block 708 to slide backward in the fixed block 707 through the connecting rod 709, the snap ring 712 can be driven to separate from the slot 713. At this time, when controlling the up and down sliding of the sliding plate 702, since the chuck 91 does not contact the mounting cavity on the sliding plate 702, after the snap ring 712 separates from the slot 713, the sliding plate 702 will not drive the chuck 91 to move, and thus the clamping relationship of the clamping component 9 cannot be released. Therefore, when pulling a certain pressing rod 710 and then rotating the knob 703 to make the sliding plate 702 move downward, the sprinkler component 5 corresponding to the pressing rod 710 will continue to complete the operation of adjusting the flow rate under the drive of the motor 601 and will not cancel the adjustment as the knob 703 rotates. On the contrary, the un-pulled pressing rod 710 will cancel the adjustment as the knob 703 rotates. Therefore, the flow rate of any pipeline 13 can be arbitrarily controlled;

[0051] The control panel 701 is provided with a plurality of label slots, and the label slots are arranged corresponding to the pressing rods 710;

[0052] For example, when the number of the nozzle assemblies 5 is six, the number of the pressing levers 710 distributed on the control panel 701 is also six. Thus, the digital labels from 1 to 6 can be used to mark which pressing lever 710 corresponds to which nozzle assembly 5, facilitating the selective control by the user.

[0053] The nozzle assembly 5 includes: an upper housing 501, a lower housing 502, and spray holes 503. The upper housing 501 is rotatably connected to the lower housing 502, and the spray holes 503 are evenly distributed on the lower side of the lower housing 502. A connecting pipe 510 is fixedly connected to the upper housing 501, and the connecting pipe 510 is rotatably and sealingly connected to the pipeline 13. An inner wall of the lower housing 502 is fixedly connected with a disc 506, and the connecting pipe 510 penetrates through the disc 506 and is rotatably connected to the disc 506. A gear ring 504 is fixedly sleeved on the outer side of the upper housing 501, and a first gear 505 meshing with the gear ring 504 is fixedly connected to the lower end of a second rotating shaft 611. Inside the lower housing 502, the spray holes 503 are separated into a first spraying area, a second spraying area, and a third spraying area by a first separating ring 508 and a second separating ring 509. The connecting pipe 510 is rotatably and sealingly connected to the first separating ring 508. A plurality of first water flow holes 512 and second water flow holes 513 are formed in the disc 506. The connecting pipe 510 communicates with the first spraying area, the first water flow holes 512 communicate with the second spraying area, and the second water flow holes 513 communicate with the third spraying area. A plurality of water collecting grooves 507 are also fixedly connected to the connecting pipe 510, and the bottom of the water collecting groove 507 is of an unsealed structure. The connecting pipe 510 communicates with the water collecting groove 507 through a water outlet 511.

[0054] The specific structure of the nozzle assembly 5 is as Figures 6-9 shown. When the adjusting assembly 6 adjusts the flow rate in the pipeline 13, the second rotating shaft 611 rotates. Therefore, the first gear 505 rotates, and under the action of the gear ring 504, the upper housing 501 can be driven to rotate, thereby driving the water collecting groove 507 to rotate on the disc 506 through the connecting pipe 510. Refer to the attached Figures 8-9As shown, the distribution of the first water flow holes 512 and the water flow holes 513 can be considered in combination. If there are three groups of water flow holes provided on the disc 506, the angle of each group is 120°. And so on. There are three layouts of the water flow holes within this 120° area, that is, one group. The first type is that there are both the first water flow holes 512 and the second water flow holes 513. The second type is that there are only the first water flow holes 512. The third type is completely closed. The interval between each type is 40°. The explanation is as follows: When the water collecting tank 507 is placed at the first type of water flow holes, that is, the water collecting tank 507 is connected to both the first water flow holes 512 and the second water flow holes 513. At this time, all three spraying areas are spraying. When the water collecting tank 507 rotates 40°, it is only connected to the first water flow holes 512. At this time, only the first spraying area and the second spraying area are performing spraying work, and the third spraying area is closed. When the water collecting tank 507 continues to rotate 40°, the water collecting tank 507 is neither connected to the first water flow holes 512 nor to the second water flow holes 513. At this time, only the connecting pipe 510 is connected to the first spraying area, that is, only the first spraying area completes the spraying work. Therefore, when the flow rate in the pipeline 13 is gradually decreased, the water collecting tank 507 can be just rotated to the area of one group through the gear transmission ratio. That is to say, first, all three spraying areas spray fertilizer. At this time, the flow rate is the largest, which can increase the coverage area. When the flow rate is adjusted to be slightly smaller, the third spraying area is closed, and the first and second spraying areas work, and the fertilizer can be sprayed and converged. When the flow rate is adjusted to the smallest, only the first spraying area is performing spraying work at this time, that is, the flow rate of the converged spraying of the nozzle assembly 5 is the most intensive. Therefore, the nozzle assembly 5 of this solution can be automatically adapted as the flow rate is adjusted, improving the applicability of the fertilization equipment.

[0055] Working principle: In the present invention, first, a fluid fertilizer is added to the fertilizer tank, the motor 601 is started, and the pump body 2 is started. The motor 601 drives a set of bevel gears 602 to rotate through the first rotating shaft 604. The bevel gears 602 drive the second rotating shaft 611 to rotate through the bevel gears 603. The second rotating shaft 611 drives the bevel gear 605 and the gear 505 to rotate. The bevel gear 605 drives the threaded drum 607 to rotate through the bevel gear 606. The rotation of the threaded drum 607 causes the screw 608 to drive the sealing head 609 to move towards the sealing member 610, thereby reducing the size of the fertilizer injection flow rate in the pipeline 13.

[0056] In the initial state of this solution, all the clamping components 9 have completed the clamping work between the second bevel gear 603 and the second rotating shaft 611. That is, when the motor 601 is turned on, under the drive of the motor 601, the flow rates of multiple pipelines 13 can be adjusted simultaneously. At the same time, the snap ring 712 is also embedded in the slot 713. When it is necessary to close the adjustment or selectively control the adjustment of a certain spray head component 5 or multiple spray head components 5, first rotate the knob 703 to drive the third rotating shaft 704 to rotate, thereby driving the second gear 705 to rotate. Under the action of the rack 706, the sliding plate 702 can be driven to move downward. Since the snap ring 712 is embedded in the slot 713 at this time, and the slide bar 711 fixedly connected to the snap ring 712 slides back and forth with the sliding plate 702, when the sliding plate 702 slides up and down, the snap ring 712 can be driven to slide up and down, thereby driving the chuck 91 to move downward through the snap ring 712. Therefore, the chuck 92 can be separated from the card slot of the second bevel gear 603, so that the clamping component 9 loses the clamping effect. The second bevel gear 603 and the second rotating shaft 611 are rotationally connected and not restricted by any means. Therefore, the first rotating shaft 604 cannot drive the second rotating shaft 611 to rotate through the first bevel gear 602 and the second bevel gear 603, and thus cannot adjust the flow rate of the pipeline 13;

[0057] When I selectively control the flow rate of a certain spray head component 5 or multiple spray head components 5, I can first pull a certain pressing rod 710 or multiple pressing rods 710. Whichever is pulled, the flow rate adjustment operation of the corresponding spray head component 5 will not be closed. The explanation is as follows: The pressing rod 710 is fixedly connected to the mounting block 708 through the connecting rod 709. In the initial state, the snap ring 712 and the slot 713 are in an embedded state. When the pressing rod 710 is pulled to drive the mounting block 708 to slide backward in the fixed block 707 through the connecting rod 709, the snap ring 712 can be driven to separate from the slot 713. At this time, when controlling the up and down sliding of the sliding plate 702, since the chuck 91 does not contact the mounting cavity on the sliding plate 702, after the snap ring 712 separates from the slot 713, the sliding plate 702 will not drive the chuck 91 to move, and thus the clamping relationship of the clamping component 9 cannot be released. Therefore, when pulling a certain pressing rod 710 and then rotating the knob 703 to make the sliding plate 702 move downward, the spray head component 5 corresponding to the pressing rod 710 will continue to complete the operation of adjusting the flow rate under the drive of the motor 601 and will not cancel the adjustment as the knob 703 rotates. On the contrary, the un-pulled pressing rod 710 will cancel the adjustment during the rotation of the knob 703. Therefore, the flow rate of any pipeline 13 can be arbitrarily controlled;

[0058] During this process, gear one 505 drives the ring gear 504 to rotate, thereby driving the upper housing 501 to rotate, and then driving the water collecting tank 507 to rotate on the disc 506. When the water collecting tank 507 is connected to both the first water flow hole 512 and the second water flow hole 513, all three spraying areas are spraying. When the water collecting tank 507 is only connected to the first water flow hole 512 afterwards, only the first spraying area and the second spraying area are spraying, and the third spraying area is closed. When the water collecting tank 507 continues to rotate, the water collecting tank 507 is neither connected to the first water flow hole 512 nor the second water flow hole 513. At this time, only the connecting pipe 510 is connected to the first spraying area, that is, only the first spraying area completes the spraying work. Therefore, when the flow rate in the pipeline 13 is gradually decreasing, the gear transmission ratio can be used to make the water collecting tank 507 just rotate to the required area. That is to say, when the first three spraying areas all spray fertilizer, the flow rate is the largest at this time, which can increase the coverage area. When the flow rate is adjusted to be slightly smaller, the third spraying area is closed, and the first and second spraying areas work, and the fertilizer can be sprayed and converged. When the flow rate is adjusted to the smallest, only the first spraying area is spraying at this time, that is, the flow rate of the converged spraying of the nozzle assembly 5 is the most intensive. Therefore, the nozzle assembly 5 of this solution can be automatically adapted with the adjustment of the flow rate, improving the applicability of the fertilization equipment. Thus, when the equipment faces crops with different planting densities, it can adjust the fertilizer injection flow rate and the spraying range according to the crop density, avoiding the waste of fertilizer, and also improving the injection density of fertilizer, making the equipment more flexible and convenient to adjust, capable of adapting to different crops, and improving the multi-channel synchronous fertilizer injection efficiency.
