Description

Technical Field

[0001] This utility model belongs to the field of weeding machine technology, specifically relating to an integrated weeding machine for soybean and corn intercropping. Background Technology

[0002] In modern agricultural production, the soybean-corn strip intercropping model has been widely promoted due to its ability to significantly improve land utilization and crop yield. However, weeding operations under this model face severe challenges: traditional single-machine weeding is difficult to adapt to the complex row spacing of alternating wide and narrow rows (such as 400mm row spacing for corn and 300mm row spacing for soybeans in the 4+2 model), and is prone to problems such as high seedling damage and low weeding efficiency; chemical weeding, on the other hand, is prone to cross-harm due to the large difference in herbicide sensitivity between soybeans and corn, and excessive use of herbicides can also cause environmental pollution and herbicide resistance problems.

[0003] In existing technologies, most weeding equipment is designed for a single function and cannot meet the needs of coordinated weed control in intercropping models. Some models are only equipped with mechanical mowing devices, which cannot accurately handle weeds between plants; while some spraying equipment suffers from uneven pesticide coverage or severe drift due to unreasonable structural layout. In addition, traditional equipment has insufficient row spacing adaptability and is difficult to adapt to intercropping models with different row spacings. Utility Model Content

[0004] This utility model provides an integrated soybean and corn intercropping weeding machine, which aims to improve the weeding efficiency and the applicability of the equipment.

[0012] For example, the main frame is provided with two first telescopic drive components, which are respectively located on both sides of the spraying device, and their output ends are respectively connected to the two side frames.

[0013] For example, a horizontal slide is installed on the side frame, and the mowing device is slidably connected to the slide.

[0014] In one possible implementation, the suspension device includes a first rod, a second rod, and a second telescopic drive member. One end of the first rod is hinged to the vehicle body, and the other end is hinged to the frame. One end of the second rod is hinged to the vehicle body, and the other end is hinged to the frame. The second rod is located below the first rod. The second telescopic drive member is mounted on the vehicle body, and its output end is connected to the second rod.

[0015] The beneficial effects of this integrated soybean-corn intercropping weeding machine are as follows: Compared with the prior art, this invention, by setting up a mowing device and a spraying device, addresses the complex row spacing of alternating wide and narrow rows in soybean-corn strip intercropping patterns.

[0025] Please refer to the following: Figure 1 and Figure 2 The present invention provides a description of the integrated soybean-corn intercropping weeding machine. The integrated soybean-corn intercropping weeding machine includes a vehicle body 10, a frame 20, a spraying device 30, and two sets of mowing devices 40. A suspension device 11 is located at the rear of the vehicle body 10, and a medicine tank 12 is also mounted on the vehicle body 10. The frame 20 is located behind the vehicle body 10 and connected to the suspension device 11. The spraying device 30 is located in the middle of the frame 20 and connected to the medicine tank 12; the spraying device 30 is used to spray medicine into the soybean rows. The two sets of mowing devices 40 are located on both sides of the spraying device 30 and are slidably connected laterally along the frame 20; the mowing devices 40 are used to plow and weed the corn rows.

[0026] It should be noted that the soybean-corn strip intercropping pattern features a complex row spacing with alternating wide and narrow rows. The soybean ridges are located in the middle, flanked by corn ridges. A spraying device 30 is positioned in the middle of the frame 20 to spray pesticides into the soybean ridges. Two sets of mowing devices 40 are located on either side of the spraying device 30 and are slidably connected laterally along the frame 20, used to weed the corn ridges. The spraying device 30 and the mowing devices 40 work together to perform weeding operations on the soybean and corn ridges respectively, adapting to the characteristics and weeding needs of different crop ridges in the intercropping pattern, thus improving the applicability of weeding in the intercropping pattern. The spraying device 30 targets the soybean ridges, and the mowing devices 40 target the corn ridges. Furthermore, the horizontal sliding connection between the mowing devices 40 and the frame 20 allows for adjustment of the working position of the mowing devices 40, changing the working row spacing during mowing, making the weeding operation more precise and avoiding damage to the crops during the weeding process.

[0027] Compared with existing technologies, the soybean-corn intercropping weeding machine provided by this utility model has a mowing device 40 and a spraying device 30 that can handle the complex row spacing of alternating wide and narrow rows in soybean-corn strip intercropping patterns. The mowing device 40 can cut weeds in the corn rows, and the spraying device 30 can spray pesticides into the soybean rows, thus simultaneously meeting the weeding needs of both crops during soybean-corn intercropping and improving weeding efficiency. The mowing device 40 is slidably mounted on the frame 20, allowing for flexible adjustment according to the position of the corn rows. This adapts to intercropping patterns with different row spacings, ensuring the weeding effectiveness of the integrated weeding machine in soybean-corn intercropping with varying row spacings and expanding the applicability of the equipment.

[0028] In one possible implementation, please refer to Figure 2 and Figure 3 The mowing device 40 includes a support frame 41, an adjusting frame 42, a walking assembly 43, and a mowing shovel 44. The support frame 41 is horizontally slidably mounted on the frame 20 and located on one side of the spraying device 30. Two connecting rods 411, spaced apart vertically, are hinged to the support frame 41. The adjusting frame 42 is hinged to the two connecting rods 411. The walking assembly 43 is mounted on the adjusting frame 42 and rolls on the ground. The walking assembly 43 supports the adjusting frame 42 and its support height is adjustable. The mowing shovel 44 is located at the bottom of the adjusting frame 42 and behind the walking assembly 43.

[0029] It should be noted that the support frame 41 can slide horizontally on the frame 20, allowing the mowing device 40 to flexibly adjust its position according to the planting row spacing of soybeans and corn, thereby adapting to different planting patterns and improving the adaptability of the integrated weeding machine to various planting environments. The adjusting frame 42 forms a four-bar linkage with the support frame 41 through two connecting rods 411. The support rods are fixed in the vertical direction, and the adjusting rods can be adjusted in the vertical direction. The walking component 43 is located on the adjusting frame 42, used for walking, and can support the adjusting frame 42. It can also change the relative height of the adjusting frame 42 to the ground by pushing and pulling the adjusting frame 42 by changing its own height. The mowing shovel 44 is located behind the walking component 43. The walking component 43 first detects and adapts to the ground conditions, and then the mowing shovel 44 performs the weeding operation. The height of the hoe of the mowing shovel 44 can be adjusted through the adjusting frame 42 and the walking component 43, which can accurately control the distance between the mowing shovel 44 and the corn seedlings, avoiding damage to the corn seedlings during the mowing process and reducing the seedling damage rate.

[0030] In some embodiments, please refer to Figure 3 The adjustment frame 42 includes a vertical frame 421, a horizontal frame 422, and an inclined frame 423. The upper and lower ends of the vertical frame 421 are hinged to two connecting rods 411 respectively. One end of the horizontal frame 422 is connected to the vertical frame 421, and the other end is provided with a grass-cutting shovel 44. The inclined frame 423 is inclined and its two ends are connected to the vertical frame 421 and the horizontal frame 422 respectively. The walking component 43 is connected to the inclined frame 423.

[0031] It should be noted that the upper and lower ends of the vertical frame 421 are hinged to two connecting rods 411, allowing the height of the adjusting frame 42 to be adjusted as needed. The horizontal frame 422 is used to mount the mowing shovel 44, extending it to a suitable position within the corn ridge for precise weeding. The inclined frame 423 is set at an angle, connecting the vertical frame 421 and the horizontal frame 422, and also providing an installation position for the walking component 43. This allows the walking component 43 to effectively support the adjusting frame 42 and adjust the relative height of the mowing shovel 44 to the ground by changing its own height, adapting to different terrains and operational requirements. The vertical frame 421, horizontal frame 422, and inclined frame 423 are interconnected to form a triangular structure. The triangle provides stability, allowing the adjusting frame 42 to withstand the resistance encountered by the mowing shovel 44 during operation, ensuring that the mowing device 40 will not deform or be damaged due to stress during operation, thus improving the reliability and durability of the entire weeding machine.

[0032] For example, please refer to Figure 3The traveling assembly 43 includes a sleeve 431, a fork 432, and a ground wheel 433; the sleeve 431 is inclinedly mounted on the inclined frame 423; the fork 432 slides through the sleeve 431 and extends out of the sleeve 431 at one end facing the ground; the ground wheel 433 is rotatably mounted at the end of the fork 432 that extends out of the sleeve 431.

[0033] It should be noted that the fork 432 can slide within the sleeve 431. By changing the position of the fork 432 within the sleeve 431, the relative height between the ground wheel 433 and the slant frame 423 can be adjusted, thereby flexibly changing the distance between the adjusting frame 42 and the ground. This allows the mowing shovel 44 to be quickly and accurately adjusted to the appropriate hoe height, ensuring weeding effectiveness while avoiding unnecessary damage to the crops. When the corn seedlings are short, the height of the mowing shovel 44 can be lowered for weeding operations closer to the ground. As the corn seedlings grow taller, the height of the mowing shovel 44 can be raised in time to prevent damage to the corn seedlings.

[0034] For examples, please refer to Figure 4 The spraying device 30 includes an infusion pipe 31, a delivery pump 32, multiple nozzles 33, and a protective component 34. The infusion pipe 31 is horizontally connected to the bottom of the frame 20. The delivery pump 32 is located on the frame 20 and connected to the medicine tank 12. The delivery pump 32 is connected to the infusion pipe 31. The nozzles 33 are spaced apart on the infusion pipe 31. The protective component 34 is located on the frame 20 and is used to shield the nozzles 33.

[0035] It should be noted that the delivery pump 32 can be a plunger pump, connected to the medicine tank 12 and each nozzle 33 via the infusion pipe 31, enabling the delivery of the medicine solution from the medicine tank 12 to each nozzle 33 for spraying. Multiple nozzles 33 are spaced apart on the infusion pipe 31, ensuring even spraying of the medicine solution within the soybean rows. Multiple nozzles 33 can cover a wider area, reducing blind spots and ensuring that weeds receive sufficient medicine solution, improving the effectiveness of chemical weed control and more effectively removing weeds from the soybean rows. The protective component 34, mounted on the frame 20, is used to shield the nozzles 33. In the soybean-corn intercropping model, soybeans and corn have different sensitivities to herbicides. The protective component 34 effectively prevents the medicine solution sprayed from the nozzles 33 from drifting towards the corn rows, preventing the medicine solution from affecting the corn rows. Through the shielding effect of the protective component 34, the medicine solution can be concentrated within the soybean rows, reducing the impact on the corn rows, lowering the risk of crop damage, and protecting the normal growth of the crops.

[0036] In one possible implementation, please refer to Figure 4 The protective component 34 includes a protective cover 341 and a baffle 342. The protective cover 341 is mounted on the frame 20 and located above and to the side of the infusion tube 31. The baffle 342 covers both ends of the infusion tube 31.

[0037] It should be noted that the protective cover 341 is located above and to the side of the nozzle 33, directly blocking the pesticide sprayed from the nozzle 33 to the sides and upwards, reducing upward and lateral drift of the pesticide. The baffles 342 located on both sides of the protective cover 341 further restrict the diffusion of the pesticide to the sides, forming a relatively enclosed space, allowing the pesticide to be sprayed more concentratedly downwards within the soybean rows. This effectively prevents the pesticide from drifting to adjacent corn rows, avoiding cross-crop damage caused by pesticide drift and protecting the normal growth of soybeans and corn. Through the blocking and guiding of the pesticide by the protective cover 341 and baffles 342, more pesticide can be accurately sprayed onto weeds within the soybean rows, reducing pesticide waste. This improves the utilization rate of the pesticide, reduces the cost of chemical pesticides, and reduces environmental pollution, meeting the requirements of green agricultural production.

[0038] In some embodiments, please refer to Figure 4 The frame 20 includes a main frame 21 and two side frames 22; the front end of the main frame 21 is connected to the suspension device 11, and a spraying device 30 is provided on the main frame 21; the two side frames 22 are slidably connected along the longitudinal direction of the main frame 21, and each of the two side frames 22 is provided with a mowing device 40.

[0039] It should be noted that both side frames 22 are longitudinally slidably connected along the main frame 21, and a mowing device 40 is installed on the side frames 22. By vertically sliding the side frames 22, the height and horizontal position of the mowing device 40 can be flexibly adjusted according to different row spacing requirements in the soybean-corn strip intercropping pattern, allowing it to accurately target the corn rows for weeding. This solves the problem of insufficient row spacing adaptability of traditional equipment, improves the adaptability of the integrated weeding machine to various planting row spacings, and expands the applicability of the equipment. A spraying device 30 is installed on the main frame 21 for spraying pesticides into the soybean rows; the mowing device 40 is installed on the side frames 22 for weeding the corn rows. This allows for functional zoning of chemical and mechanical weeding, ensuring that the two weeding methods do not interfere with each other and enabling more efficient operation.

[0040] For example, please refer to Figure 5 The main frame 21 is provided with two first telescopic drive members 23. The two first telescopic drive members 23 are respectively located on both sides of the spraying device 30, and their output ends are respectively connected to the two side frames 22.

[0041] It should be noted that the first telescopic drive component 23 can be a cylinder. The two first telescopic drive components 23 are respectively located on both sides of the spraying device 30, which can drive the two side frames 22 to slide vertically up and down on the main frame 21 to adjust the height of the mowing device 40 so that the mowing device 40 can accurately aim at the corn row for weeding.

[0042] For examples, please refer to Figure 4A slide rail 221 is horizontally provided on the side frame 22, and the mowing device 40 is slidably connected to the slide rail 221.

[0043] It should be noted that the mowing device 40 can slide horizontally along the slide rail 221 on the side frame 22. This allows the position of the mowing device 40 in the horizontal direction to be adjusted according to the actual row spacing of soybean and corn planting, ensuring that the mowing shovel 44 accurately aligns with the weeds in the corn ridges, improving the targeting and precision of the weeding operation. Through the sliding cooperation between the slide rail 221 and the mowing device 40, the integrated weeding machine can adapt to various different row spacing requirements. Furthermore, the mowing device 40, which can slide horizontally along the slide rail 221, and the first telescopic drive component 23, which can drive the side frame 22 to slide vertically, work together to achieve precise alignment of the mowing device 40 with the corn ridges, thus achieving precise cutting of the weeds within the corn ridges.

[0044] In one possible implementation, please refer to Figure 6 The suspension device 11 includes a first rod 111, a second rod 112, and a second telescopic drive member 113. One end of the first rod 111 is hinged to the vehicle body 10, and the other end is hinged to the frame 20. One end of the second rod 112 is hinged to the vehicle body 10, and the other end is hinged to the frame 20. The second rod 112 is located below the first rod 111. The second telescopic drive member 113 is mounted on the vehicle body 10, and its output end is connected to the second rod 112.

[0045] It should be noted that the second telescopic drive component 113 can be an electric push rod. The first rod 111, the second rod 112, the vehicle body 10, and the frame 20 together form a four-bar linkage structure. Through the telescopic movement of the second telescopic drive component 113, the angle between the second rod 112 and the vehicle body 10 is changed, thereby driving the frame 20 to move up and down and adjust its angle. The adjustable height and angle of the frame 20 allow the weeding machine to better adapt to the agronomic requirements of different growth stages. When the height of the soybean ridge increases, the frame 20 can be raised through the suspension device 11 to improve the passability of the main frame 21 above the soybean ridge. After the frame 20 is raised as a whole, the first telescopic drive component 23 drives the side frame 22 to slide down along the main frame 21 to offset the change in the height of the mowing device 40, so that the mowing device 40 is still at a suitable hoe height, achieving precise cutting of weeds in the corn ridge.

[0046] The above description is only a preferred embodiment of the present utility model and is 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.
