Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and in particular to a mid-term chemical weeding device for corn. Background Technology

[0002] Mid-stage chemical weed control is crucial for ensuring corn yield. When corn reaches the mid-stage of growth, if previous weed control was incomplete or weeds have re-emerged, highly effective herbicides such as nicosulfuron, mesotrione, and benzoxazine can be used for foliar spraying to control both grasses and broadleaf weeds. When applying herbicides, pay attention to weather conditions to avoid affecting efficacy during rainy days, and ensure that the herbicide solution does not spray onto the corn stalks and leaves to prevent phytotoxicity. At the same time, strictly control the concentration and dosage, adjusting flexibly according to soil and weed conditions to achieve optimal weed control and ensure safe corn growth.

[0003] With the large-scale standardized planting of corn, weeds in cornfields have developed resistance to herbicides. Chemical weeding during the 3-5 leaf stage of corn is incomplete, which seriously affects the later growth and development of corn. Weeds compete with corn seedlings for fertilizer, water, and sunlight, affecting corn yield. The traditional weeding method is manual weeding, which is inefficient, labor-intensive, and poses safety hazards in high temperatures. Herbicides are also used to control weeds in corn, but herbicides are more harmful to human health and have higher risks. Therefore, a mid-term chemical weeding device for corn is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low efficiency, high workload, and safety hazards associated with manual weeding in high temperatures, as well as the use of herbicides for weeding corn, which poses significant risks to human health. Therefore, this invention proposes a mid-term chemical weeding device for corn.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mid-stage chemical weed control device for corn includes a support frame. A connecting rod is fixedly connected to the outer side of the support frame, and wheels are symmetrically and movably connected to both sides of the support frame. Multiple adjustment components are provided on the support frame, including nozzles and pins movably connected to the outer side of the support frame, and a fixing rod fixedly connected to the outer side of the support frame. The nozzles can be adjusted in position on the fixing rod via the pins, allowing the nozzles to be adjusted according to the height of the weeds. Multiple rubber plugs are movably connected to the outer side of the support frame, and the rubber plugs can individually block the multiple nozzles.

[0007] The main output pipe is fixedly connected to the side of the support frame away from the connecting rod, and the fixing blocks are symmetrically fixedly connected to the side of the support frame close to the main output pipe. The fixing blocks are fixedly connected to the main output pipe, and the main output pipe is fixed to the support frame by the fixing blocks.

[0008] The above technical solution further includes:

[0009] An output pipe head is fixedly connected to the side of the support frame near the connecting rod. The output pipe head is fixedly connected to the main output pipe, and the main output pipe is fixedly connected to the rubber stopper. The external medicine is connected to the output pipe head through a water pipe.

[0010] A rotating rod is rotatably connected to the outside of the rubber stopper. The rotating rod is movably connected to the main output pipe. The rotation of the rotating rod causes the rubber stopper to rotate inside the main output pipe, and the rubber stopper adjusts multiple nozzles.

[0011] Multiple first connecting pipes are fixedly connected to the outside of the main output pipe. The multiple first connecting pipes are threadedly connected to the second connecting pipe. An elastic tube is fixedly connected to the end of the second connecting pipe away from the first connecting pipe. The elastic tube is connected to the first connecting pipe through the second connecting pipe. The medicine flows into the elastic tube through the main output pipe.

[0012] The elastic tube is fixedly connected to the nozzle, a connecting plate is fixedly connected to the outside of the nozzle, a housing is fixedly connected to the outside of the connecting plate, and the connecting plate is slidably connected to the fixing rod. The liquid medicine flows through the elastic tube to the nozzle, so that the nozzle sprays the liquid medicine on the weeds.

[0013] A spring is fixedly connected inside the housing. The spring is fixedly connected to a pin, the pin is movably connected to the housing, and the pin is movably connected to a connecting plate. When the pin pulls outward to compress the spring, the spring causes the pin to return to its original position.

[0014] The outer side of the fixing rod is provided with multiple positioning grooves, and the pin is movably connected to the positioning grooves. The nozzle can be adjusted according to the growth of weeds through the pin and the positioning grooves.

[0015] This utility model has the following beneficial effects:

[0016] 0. In this utility model, the connecting rod in the adjusting component is directly connected to the traction machine, and multiple nozzles are used to accurately spray pesticides between the rows of corn. The nozzles can be flexibly adjusted according to the growth of weeds through pins, which effectively improves the efficiency and effect of weeding, reduces the cost and risk of manual weeding, and ensures the later growth and development and yield of corn.

[0023] 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.

[0024] Example 1

[0025] like Figures 1-4 As shown, this utility model proposes a mid-term chemical weeding device for corn. The device includes a support frame 1, a connecting rod 2 fixedly connected to the outside of the support frame 1, wheels 3 symmetrically and movably connected to both sides of the support frame 1, and multiple adjustment components on the support frame 1. The adjustment components include a nozzle 13 and a pin 17 movably connected to the outside of the support frame 1, and a fixing rod 11 fixedly connected to the outside of the support frame 1. The nozzle 13 can be adjusted in position on the fixing rod 11 via the pin 17, so that the nozzle 13 can be adjusted according to the height of the weeds. Multiple rubber plugs 18 are movably connected to the outside of the support frame 1, and the rubber plugs 18 can block the multiple nozzles 13 respectively.

[0026] A main output pipe 5 is fixedly connected to the side of the support frame 1 away from the connecting rod 2. A fixing block 4 is symmetrically fixedly connected to the side of the support frame 1 close to the main output pipe 5. The fixing block 4 is fixedly connected to the main output pipe 5. The main output pipe 5 is fixed to the support frame 1 by the fixing block 4.

[0027] The support frame 1 is fixedly connected to the output tube head 10 on the side near the connecting rod 2. The output tube head 10 is fixedly connected to the main output tube 5. The main output tube 5 is fixedly connected to the rubber stopper 18. The external medicine is connected to the output tube head 10 through a water pipe.

[0028] A rotating rod 9 is rotatably connected to the outside of the rubber stopper 18. The rotating rod 9 is movably connected to the main output pipe 5. The rotation of the rotating rod 9 causes the rubber stopper 18 to rotate inside the main output pipe 5. The rubber stopper 18 adjusts the multiple nozzles 13.

[0029] In this embodiment, when the device is needed, it is connected to the traction machine through the ring connection at the end of the connecting rod 2. The wheels 3 on both sides of the support frame 1 support the entire device, improving the stability of the device's movement. At this time, the external spraying box is connected to the output pipe head 10 through the water pipe. The pesticide solution flows into the main output pipe 5 through the output pipe head 10, and then flows to the nozzles 13 through the main output pipe 5, so that the nozzles 13 spray the weeds. When there are only one, two, or three rows of corn that need to be sprayed, the rotating rod 9 is rotated. The rotating rod 9 drives the rubber stopper 18 to block the position of the pesticide solution flowing in the main output pipe 5. In this way, the number of nozzles 13 can be adjusted according to how many rows of corn are left, effectively avoiding resource waste and improving weeding efficiency.

[0030] Example 2

[0031] like Figures 1-4 As shown, based on Embodiment 1, a plurality of first connecting pipes 6 are fixedly connected to the outside of the main output pipe 5. The plurality of first connecting pipes 6 are threadedly connected to the second connecting pipe 7. An elastic pipe 8 is fixedly connected to the end of the second connecting pipe 7 away from the first connecting pipe 6. The elastic pipe 8 is connected to the first connecting pipe 6 through the second connecting pipe 7. The medicine flows into the elastic pipe 8 through the main output pipe 5.

[0032] The elastic tube 8 is fixedly connected to the nozzle 13. A connecting plate 14 is fixedly connected to the outside of the nozzle 13. A housing 15 is fixedly connected to the outside of the connecting plate 14. The connecting plate 14 is slidably connected to the fixing rod 11. The liquid medicine flows through the elastic tube 8 to the nozzle 13, so that the nozzle 13 sprays the liquid medicine on the weeds.

[0033] A spring 16 is fixedly connected inside the housing 15. The spring 16 is fixedly connected to the pin 17, the pin 17 is movably connected to the housing 15, and the pin 17 is movably connected to the connecting plate 14. When the pin 17 pulls outward to compress the spring 16, the spring 16 causes the pin 17 to return to its original position.

[0034] Multiple positioning slots 12 are provided on the outer side of the fixing rod 11. The pin 17 is movably connected to the positioning slots 12. The nozzle 13 can be adjusted according to the growth of weeds through the pin 17 and the positioning slots 12.

[0035] In this embodiment, when weeding is required, the nozzle 13 can be slid on the fixed rod 11 by the connecting plate 14 based on the weed growth situation on site. The pin 17 is pulled outward, causing the pin 17 to compress the spring 16 away from the positioning groove 12. This causes the nozzle 13 to adjust its position according to the weeds. By releasing the pin 17, the compressed spring 16 rebounds the pin 17, fixing the pin 17 on the positioning groove 12. In this way, the nozzle 13 is fixed in the adjusted position by the pin 17, which effectively improves the weeding efficiency and effect, and ensures the later growth and development and yield of corn.
