Description

Technical Field

[0001] This utility model relates to the field of agricultural planting machinery and equipment technology, and in particular to a fertilization device for corn-soybean strip intercropping. Background Technology

[0002] In today's agricultural production, which is constantly pursuing high efficiency, greenness and sustainable development, the innovation and optimization of planting patterns have become a key path to improve land productivity and ensure food security. Corn-soybean strip intercropping, as an advanced planting pattern, has emerged. Through clever spatial layout, it usually adopts a planting method of two rows of corn and three to four rows of soybeans, allowing corn and soybeans to grow together on the same land. This pattern makes full use of the differences between the two crops in terms of growth cycle, light requirements and nutrient utilization, and achieves efficient utilization of light, heat, water and fertilizer resources.

[0003] However, existing fertilization devices suffer from problems such as insufficient and uneven mixing of water and fertilizer during use. In addition, during the fertilizer dissolution process, some insoluble substances remain in the fertilization device, resulting in waste accumulation and even blockage of pipes, which affects the efficiency of fertilization.

[0004] The existing patent (publication number: CN221784677U) discloses a fertilization device for soybean-corn intercropping. By setting up a storage tank and a fertilizer dissolving tank, the fertilizer dissolving and spraying equipment are carried out separately. On the one hand, this facilitates the filtration of impurities to avoid clogging the channels. On the other hand, while the storage tank is spraying, the fertilizer dissolving tank can simultaneously mix and prepare fertilizer and water, and can replenish the water and fertilizer solution into the storage tank in a timely manner, which greatly improves the fertilization efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions. However, current fertilization devices for corn-soybean strip intercropping typically lack a structure for independent storage and precise delivery of corn and soybean-specific fertilizers. This makes it difficult to process fertilizers for the two crops separately, resulting in insufficient fertilizer mixing, accumulation of insoluble particles clogging pipes, and reduced fertilization efficiency. Furthermore, the lack of a flexible adjustment structure to accommodate different row spacings makes it difficult to adjust the fertilization position based on row spacing differences in strip planting. This leads to fertilizer spraying deviating from the target area and affecting fertilization accuracy.

[0006] Therefore, a fertilization device for corn-soybean strip intercropping is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a fertilization device for corn-soybean strip intercropping, which solves the problems of existing fertilization devices for corn-soybean strip intercropping that typically lack a structure for independent storage and precise delivery of corn and soybean-specific fertilizers, making it inconvenient to process fertilizers for the two types of crops separately. This results in insufficient fertilizer mixing, accumulation of insoluble particles clogging the pipes, affecting fertilization efficiency, and the lack of a flexible adjustment structure to accommodate different row spacings. This makes it difficult to adjust the fertilization position according to the row spacing differences in strip planting, causing fertilizer spraying to deviate from the target area and affecting fertilization accuracy.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fertilization device for corn-soybean strip intercropping, comprising a base, a dual-path fertilizer distribution component on the top of the base, a row spacing adjustment component on the outer side of the dual-path fertilizer distribution component, a support frame fixedly connected to the top of the base, a dual-material separation chamber fixedly connected to the inner side of the support frame, a top cover snapped onto the top of the dual-material separation chamber, a screw conveyor fixedly connected to the bottom of each dual-material separation chamber, a mixing cylinder fixedly connected to the inner side of the support frame, the mixing cylinder communicating with the screw conveyor, a rotary motor fixedly connected to the top of the mixing cylinder, and mixing blades fixedly connected to the output end of the rotary motor.

[0014] Preferably, the top of the mixing drum is connected to a feeding port, and a sealing cap is provided on the outside of the feeding port.

[0015] Preferably, the bottom of the mixing drum is connected to a conveying pipe, and a micro conveying pump is provided on the outside of the conveying pipe, which is connected to the fertilizer spraying head.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application achieves the effect of independent storage, precise delivery and full mixing of special fertilizers for corn and soybeans through the dual-path fertilizer distribution component, thereby improving fertilizer utilization and fertilization uniformity. Compared with the problem of insufficient fertilizer mixing and easy pipe blockage in traditional fertilizer application devices, this component can realize the separate delivery, dynamic mixing and anti-blocking functions of the two types of fertilizers, and solve the problems of crop nutrient imbalance caused by uneven fertilizer mixing, pipe blockage caused by the accumulation of insoluble particles, and fertilization interruption caused by low efficiency of manual fertilizer mixing in traditional methods.

[0018] 2. This application achieves the effect of precisely adapting the fertilization position to different strip planting row spacings and flexibly adjusting the nozzle angle through the row spacing adjustment component, thereby improving the device's adaptability to complex planting patterns and the accuracy of fertilization.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A fertilization device for corn-soybean strip intercropping includes a base 1. A dual-path fertilizer distribution component 4 is provided on the top of the base 1. A row spacing adjustment component 5 is provided on the outer side of the dual-path fertilizer distribution component 4. The dual-path fertilizer distribution component 4 includes a support frame 401 fixedly connected to the top of the base 1. A dual-material separation chamber 402 is fixedly connected to the inner side of the support frame 401. A top cover 403 is snapped onto the top of the dual-material separation chamber 402. A screw conveyor 404 is fixedly connected to the bottom of each dual-material separation chamber 402. A mixing cylinder 405 is fixedly connected to the inner side of the support frame 401. The mixing cylinder 405 is connected to the screw conveyor 404. A rotary motor 406 is fixedly connected to the top of the mixing cylinder 405. A mixing blade 407 is fixedly connected to the output end of the rotary motor 406.

[0029] In this embodiment: By opening the top cover 403 of the dual-material separation chamber 402, corn high-nitrogen fertilizer and soybean high-phosphorus and potassium fertilizer are added into the chamber respectively. Then, the top cover 403 is closed tightly to prevent the fertilizer from getting damp. After fertilization begins, the two sets of screw conveyors 404 at the bottom of the dual-material separation chamber 402 are started simultaneously. The internal screw blades rotate, pushing the two types of fertilizers into the connected mixing drum 405 respectively. The corn fertilizer and soybean fertilizer are transported through independent channels to avoid premature mixing and nutrient imbalance. If water or liquid fertilizer needs to be added, it is added through the feeding port 2 at the top of the mixing drum 405 and the sealing cap 3 is tightened. Then, the rotary motor 406 at the top of the mixing drum 405 is started, driving the mixing blades 407 to rotate at high speed. The blades work with the drum wall to fully mix the solid fertilizer and liquid, breaking up insoluble particles to prevent clogging and forming a uniform fertilizer solution. Finally, the micro-pump 15 at the bottom of the mixing drum 405 pressurizes and delivers the solution to the fertilizer nozzle 509 through the delivery pipe 14 to complete the fertilization.

[0030] Specifically, such as Figure 3 As shown, the row spacing adjustment component 5 includes an adjustment frame 501 fixedly connected to the outside of the support frame 401. A drive motor 502 is fixedly connected to the top of the adjustment frame 501. A longitudinal lead screw 503 is fixedly connected to the output end of the drive motor 502. A transverse support frame 504 is threadedly connected to the outside of the longitudinal lead screw 503.

[0031] Specifically, such as Figure 3 As shown, a connecting rod 505 is slidably connected inside the transverse support frame 504. A positioning groove 506 is provided on the top of the connecting rod 505. A positioning rod 507 is slidably connected to the top of the transverse support frame 504. The side of the positioning rod 507 away from the transverse support frame 504 is engaged with the positioning groove 506.

[0032] Specifically, such as Figure 3 As shown, a fixing plate 508 is fixedly connected to the outer side of the connecting support rod 505, and a fertilizer spraying head 509 is provided on the outer side of the fixing plate 508.

[0033] In this embodiment: First, the drive motor 502 at the top of the adjusting frame 501 is started, and its output end drives the longitudinal lead screw 503 to rotate. Since the longitudinal lead screw 503 is threadedly connected to the transverse support frame 504, the transverse support frame 504 moves along the axial direction of the lead screw until it is roughly aligned with the longitudinal range of the crop planting strip. Then, according to the actual spacing between the corn row and the soybean row, the connecting support rod 505 is pushed to slide within the transverse support frame 504. The fixing plate 508 on the outside of the connecting support rod 505 moves with it, thereby adjusting the transverse position of the fertilizer spray nozzle 509. When the nozzle is aligned with the target crop row, the positioning rod 507 at the top of the transverse support frame 504 is slid so that its end is engaged in the positioning groove 506 at the top of the connecting support rod 505. The connecting support rod 505 is fixed by mechanical engagement to prevent the nozzle from shifting during fertilization, so as to complete the row spacing adaptation and ensure that the fertilizer is accurately sprayed into the planting rows of the two types of crops.

[0034] Specifically, such as Figure 6 As shown, an angle adjustment seat 6 is fixedly connected to the outside of the fixed plate 508. A locking knob 7 is provided on the outside of the angle adjustment seat 6. An installation seat 8 is fixedly connected to the side of the angle adjustment seat 6 away from the fixed plate 508. The installation seat 8 is fixedly connected to the fertilizer spray head 509.

[0035] Specifically, such as Figure 5 As shown, a drive mechanism 9 is fixedly connected inside the base 1, a front wheel 10 is rotatably connected to the front side of the base 1, and the front wheel 10 is connected to the drive mechanism 9 in a transmission connection. A rotating support 11 is fixedly connected to the rear side of the base 1, a rotating rod 12 is rotatably connected to the top of the rotating support 11, and a steering wheel 13 is fixedly connected to the bottom of the rotating rod 12.

[0036] In this embodiment: By setting up an angle adjustment seat 6, a locking knob 7, and a mounting seat 8, after the lateral position of the fertilizer spray head 509 is fixed by the connecting support rod 505 and the positioning rod 507, the operator needs to adjust the spray head angle according to the different root distribution characteristics of corn and soybean. Corn roots are deeper and require deeper fertilization, while soybean roots are shallower and require shallower spraying. At this time, first loosen the locking knob 7 on the angle adjustment seat 6 on the outside of the fixing plate 508. Since the mounting seat 8 is fixedly connected to the fertilizer spray head 509, rotating the mounting seat 8 will drive the fertilizer spray head 509 to rotate synchronously until the spray head angle meets the fertilization depth requirements. After the adjustment is completed, tighten the locking knob 7. The knob's squeezing action on the angle adjustment seat 6 fixes the position of the mounting seat 8, ensuring that the fertilizer spray head 509 will not be affected by equipment vibration during fertilization. The angle is changed to precisely spray fertilizer onto the root zone of two types of crops. The system consists of a drive mechanism 9, a front wheel 10, a rotating support 11, a rotating rod 12, and a steering wheel 13. Before the equipment is started, the drive mechanism 9 inside the base 1 is in standby mode. When the equipment needs to be moved to the fertilization site, the drive mechanism 9 is activated, and its power is transmitted to the front wheel 10 on the front side of the base 1 through the transmission structure, causing the front wheel 10 to rotate and generate forward power. At the same time, the operator holds the top of the rotating rod 12 and adjusts the direction of the bottom steering wheel 13 by flexibly rotating the rotating rod 12 on the rotating support 11 on the rear side of the base 1. When the rotating rod 12 rotates clockwise, the steering wheel 13 deflects to the right, and when it rotates counterclockwise, it deflects to the left, thereby controlling the direction of the equipment's movement to meet the fertilization location requirements of different plots.

[0037] Specifically, such as Figure 4 As shown, the top of the mixing cylinder 405 is connected to a feeding port 2, and a sealing cap 3 is provided on the outside of the feeding port 2.

[0038] Specifically, such as Figure 6 As shown, the bottom of the mixing drum 405 is connected to a conveying pipe 14, which is connected to the fertilizer spray nozzle 509. A micro conveying pump 15 is installed on the outside of the conveying pipe 14.

[0039] In this embodiment: By setting up a feeding port 2 and a sealing cap 3, when the dual-path fertilizer distribution component 4 needs to be replenished with water or liquid fertilizer, the operator first opens the sealing cap 3 on the outside of the feeding port 2 at the top of the mixing drum 405, pours the required liquid into the mixing drum 405 from the feeding port 2, and after adding, promptly closes the sealing cap 3 to prevent the liquid in the drum from splashing out due to centrifugal force when the rotary motor 406 drives the mixing blades 407 to stir at high speed, thus avoiding contamination of the fertilizer solution or affecting the stirring effect, and ensuring the purity of subsequent fertilization. By setting up a delivery pipe 14 and a micro delivery pump 15, when the liquid in the mixing drum 405 is replenished... After the fertilizer and liquid are thoroughly mixed by the mixing blades 407, the micro-pump 15 on the outside of the delivery pipe 14 is started. When the micro-pump 15 is working, it generates pressure and pressurizes the fertilizer solution at the bottom of the mixing drum 405 to the fertilizer nozzle 509 through the delivery pipe 14. The delivery pipe 14 is made of corrosion-resistant material, which can be adapted to various fertilizer solutions and is not easy to clog. Throughout the fertilization process, the micro-pump 15 runs continuously and pushes the fertilizer solution along the delivery pipe 14 at a uniform speed through stable pressure, ensuring that the fertilizer nozzle 509 always has a sufficient amount of fertilizer solution sprayed out, and avoiding uneven fertilization due to interruption of delivery.

[0040] Working Principle: When using this corn-soybean strip intercropping fertilization device, the equipment status first needs to be adjusted according to the corn-soybean strip layout of the planting plot. The operator first opens the top cover 403 of the dual-material separation chamber 402 and adds corn-specific fertilizer and soybean-specific fertilizer to the dual-material separation chamber 402 respectively. After adding, the top cover 403 is closed tightly to ensure that the fertilizer will not get damp or spill during storage. At this time, the drive mechanism 9 inside the base 1 starts, driving the front wheel 10 to rotate. At the same time, the operator adjusts the direction of the steering wheel 13 by rotating the rod 12. The rotating rod 12 rotates flexibly on the rotating support 11. With the driving force of the front wheel 10, the device is smoothly moved to the starting position of the plot that needs fertilization. Next, the row spacing is adjusted to suit the needs of the planting plot. The planting strip spacing for corn and soybeans is adjusted. The adjusting frame 501 provides stable support for row spacing adjustment, while the drive motor 502 starts, its output driving the longitudinal lead screw 503 to rotate. Since the longitudinal lead screw 503 is threadedly connected to the transverse support frame 504, the rotation of the longitudinal lead screw 503 is converted into linear movement of the transverse support frame 504, adjusting its position along the axial direction of the longitudinal lead screw 503 until it is roughly aligned with the longitudinal area of ​​the crop planting strip. Subsequently, the operator, according to the specific spacing of the corn and soybean rows, pushes the connecting rod 505 to slide within the transverse support frame 504. The sliding of the connecting rod 505 causes the outer fixing plate 508 to move synchronously, thereby adjusting the transverse position of the fertilizer spraying head 509. When the nozzle 509 is aligned with the target crop row, the positioning rod 507 on the top of the sliding transverse support frame 504 is slid, causing the end of the positioning rod 507 away from the transverse support frame 504 to engage with the positioning groove 506 on the top of the connecting support rod 505. The tight engagement between the positioning rod 507 and the positioning groove 506 fixes the position of the connecting support rod 505, preventing the fertilizer nozzle 509 from shifting due to equipment vibration during fertilization. Afterward, the operator loosens the locking knob 7 on the outside of the angle adjustment seat 6. Based on the crop root distribution characteristics and fertilization depth requirements, the operator rotates the mounting seat 8 to adjust the angle of the fertilizer nozzle 509. The mounting seat 8 is fixedly connected to the fertilizer nozzle 509, and the rotation of the mounting seat 8 directly changes the spray direction of the fertilizer nozzle 509. After the angle is adjusted appropriately, the locking knob is tightened. Tighten knob 7 to press and fix angle adjustment seat 6, keeping fertilizer nozzle 509 at the preset angle to ensure precise application of fertilizer to the target area. After row spacing adjustment, the screw conveyor 404 at the bottom of the dual-material separation chamber 402 is activated. Its rotating screw blades gradually push the fertilizer in the chamber to the output end. Corn-specific fertilizer and soybean-specific fertilizer enter the mixing drum 405 through their respective screw conveyors 404, achieving independent conveying of the two types of fertilizers and avoiding nutrient imbalance caused by mixing. If water or liquid fertilizer needs to be added, open the sealing cover 3 on the outside of the feeding port 2 at the top of the mixing drum 405, add the material through the feeding port 2, and then tighten the sealing cover 3 to prevent liquid from splashing out or debris from entering during mixing.The rotary motor 406 at the top of the mixing drum 405 starts, and its output drives the mixing blades 407 to rotate at high speed inside the drum. The mixing blades 407 cooperate with the drum wall to fully mix the fertilizer and added liquid entering the drum, uniformly mixing the solid fertilizer and liquid, and breaking up difficult-to-dissolve particles in the fertilizer to prevent subsequent pipe blockage. After mixing is completed, the micro-pump 15 at the bottom of the mixing drum 405 starts, pressurizing and conveying the uniformly mixed fertilizer solution to the fertilizer nozzle 509 through the delivery pipe 14. The delivery pipe 14 is kept full under the pressure of the micro-pump 15 to ensure that the fertilizer solution is continuously and stably supplied. The fertilizer spray nozzle 509 directs the fertilizer solution to the corn and soybean rows. During the fertilization process, the drive mechanism 9 of the base 1 continuously drives the front wheel 10 forward at a constant speed. The rotating rod 12 and steering wheel 13 work together to adjust the direction of travel, ensuring smooth movement along the crop planting belt. The fertilizer spray nozzle 509 precisely sprays the received fertilizer solution at a preset angle and flow rate near the roots of the corn and soybean rows. The angle adjustment of the fertilizer spray nozzle 509 in the corn rows allows for deeper application of fertilizer to the concentrated root area, while the fertilizer spray nozzle 509 in the soybean rows applies fertilizer more superficially to suit the root distribution characteristics. Once the fertilization operation for the plot is completed, all drive components are shut off, and the equipment stops operating.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
