Description

Technical Field

[0001] The utility model belongs to the technical field of corn stalk processing machinery, and in particular relates to a device for spraying medicine on corn stalks. Background Art

[0002] Corn stalks are the product of plant photosynthesis and a valuable biological resource. However, due to poor utilization, large amounts of stalks can be seen being burned during the summer and autumn harvest seasons. The billowing smoke not only wastes resources, but also becomes the culprit of environmental pollution.

[0003] The most commonly used ecological treatment method for corn straw after harvest is to return it to the field. However, after corn is harvested, the remaining straw is prone to breed various pests and diseases, which will bring a series of troubles to the growth of crops in the next season. For example, wheat in that season showed low germination rate, yellow seedlings, weak seedlings and even dead seedlings, which not only did not increase production, but actually reduced production. Therefore, after corn is harvested, people spray straw composting agents and insecticides (fungicides) on the straw at the same time, which plays an important role in preventing and controlling pests and diseases.

[0004] However, since corn stalks grow high, people need to hold the spray rod to the top of the stalks, which makes the workers very tired and the labor efficiency is still very low. Therefore, a device for spraying corn stalks is proposed.

[0005] Therefore, a device for spraying corn stalks is proposed. Utility Model Content

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 6 As shown, this embodiment provides a device for spraying corn stalks, comprising:

[0036] A water tank 6 is fixedly connected to the rear part of the frame 1. A plurality of positioning posts 7 are abutted around the water tank 6. The positioning posts 7 are fixedly connected to the frame 1.

[0037] The width adjustment assembly is fixedly connected to the lower part of the rear end of the frame 1, and driven wheels 8 are fixedly connected to both sides of the width adjustment assembly;

[0038] The landing gear assembly is fixed to the positioning column 7 at the rear end of the frame 1;

[0039] The medicine spraying assembly is fixedly connected to the rear end of the landing gear assembly and is connected to the water tank 6 through a water pipe 9.

[0040] The driving component 2 can be a common motor in the prior art, etc. The driving component 2 drives the driving wheel 3 forward, thereby driving the entire device forward. During the forward process, the steering of the device is controlled by the steering wheel 4; the frame 1 is erected at a position higher than the corn stalks, and the driving wheel 3 and the driven wheel 8 both travel in the gaps between the ridges where the corn is planted. Due to the different corn planting intervals, the distance between the two driven wheels 8 can be adjusted by the width adjustment component, so that the driving wheel 3 is at the center interval, and the two driven wheels 8 are symmetrically located at the intervals on both sides of the interval where the driving wheel 3 is located, which can adapt to corn fields with different planting intervals and enable the device to travel in the corn field without colliding with the stalks; the water tank 6 is filled with medicine in advance, and the height of the spraying component can be adjusted through the landing gear component according to the height of the corn stalks, so that the medicine in the water tank 6 is sprayed above the stalks. The corn stalks can be sprayed with medicine by moving the vehicle body while spraying, which saves time and effort, accelerates the decomposition of the stalks, and prevents the stalks from breeding diseases and pests.

[0041] A further optimized solution is that the width adjustment component includes a two-way telescopic hydraulic cylinder 10, the middle part of which is fixedly connected to the bottom tail end of the frame 1, and the two movable ends of the two-way telescopic hydraulic cylinder 10 are respectively fixedly connected to connecting rods 11, and the bottom end of the connecting rod 11 is rotatably connected to the driven wheel 8.

[0042] The two-way telescopic hydraulic cylinder 10 can be used to extend and retract, and the positions of the driven wheels 8 on both sides can be adjusted at the same time to adapt to different corn planting intervals. Moving through the planting intervals is also conducive to stable movement.

[0043] A further optimized solution is that the landing gear assembly includes a fixed plate 12 and a support frame 13, the fixed plate 12 is fixedly connected to the top of the positioning column 7 at the rear end of the frame 1, and the upper and lower sides of the fixed plate 12 are rotatably connected to the first rotating shaft 14 respectively; the two ends of the first rotating shaft 14 are rotatably connected to the rotating rods 15, and the two rotating rods 15 connected to the same first rotating shaft 14 are rotatably connected to the second rotating shaft 16 at one end away from the first rotating shaft 14; the two second rotating shafts 16 are fixedly connected to the side of the support frame 13 close to the fixed plate 12, one above and one below, respectively, and the spraying assembly is fixed to the lower end of the support frame 13; a hydraulic telescopic rod 17 is connected between the first rotating shaft 14 located at the bottom and the second rotating shaft 16 located at the top, and one end of the hydraulic telescopic rod 17 is rotatably connected to the first rotating shaft 14, and the other end is rotatably connected to the second rotating shaft 16.

[0044] The fixed plate 12, the support frame 13, the first rotating shaft 14 and the second rotating shaft 16 together form a planar connecting rod mechanism, and the support frame 13 can be lifted or lowered by the push of the hydraulic telescopic rod 17; when the hydraulic telescopic rod 17 is extended, the support frame 13 rises, and when the hydraulic telescopic rod 17 is contracted, the support frame 13 falls.

[0045] Furthermore, the hydraulic telescopic rod 17 is preferably a multi-stage hydraulic telescopic rod 17, which can increase the stroke of the hydraulic telescopic rod 17 within a limited space.

[0046] According to a further optimized solution, the spraying assembly includes a branch pipe 18 , which is fixed along the bottom end of the support frame 13 , and a plurality of spray heads 19 are evenly connected below the branch pipe 18 , and the middle of the branch pipe 18 is connected to the water pipe 9 .

[0047] The water pipe 9 introduces the medicine into the branch pipe 18, and then sprays it out through the nozzle 19 below the branch pipe 18;

[0048] Furthermore, the distance between the nozzles 19 should not be greater than the spraying radius of the nozzles 19 to achieve full coverage of the medicine when spraying.

[0049] According to a further optimized solution, the two sides of the support frame 13 are detachably connected with extension frames 20, the bottom end of the extension frame 20 is fixedly connected with an extension tube 21, and the bottom end of the extension tube 21 is evenly connected with a plurality of nozzles 19.

[0050] The extension frame 20 can increase the area of ​​the single displacement spraying and improve the spraying efficiency.

[0051] According to a further optimized solution, two connectors 22 are protruded from one side of the extension frame 20 close to the support frame 13 , and the connectors 22 are connected to the support frame 13 by bolts 23 .

[0053] When the extension tube 21 is not installed, the internal thread of the connecting tube 24 is connected to the plug to prevent the medicine from flowing out. When the extension tube 21 needs to be installed, the plug is rotated and removed, and then the extension tube 21 is screwed and tightened to make the extension tube 21 and the branch pipe 18 threaded and sealed.

[0054] According to a further optimized solution, the extension frame 20 is in the shape of a right triangle, and its width gradually decreases from the support frame 13 toward the outside.

[0055] The triangular extension frame 20 can reduce the weight of both ends of the support frame 13, making the structure more stable and preventing the support frame 13 from being subjected to a large bending force.
