Description

Technical Field

[0001] This utility model relates to the field of weeding devices, and in particular to a weeding device for corn-soybean strip intercropping. Background Technology

[0002] Corn-soybean strip intercropping is a green and efficient planting model that has been innovatively developed based on traditional intercropping. Strip planting, also known as strip field planting, is a stable and income-increasing planting method that involves planting two or more crops in strips of a certain width. The main difference between it and the original intercropping and relay cropping is that in strip planting, different crops are not planted in single rows, but in two or more rows of "strips" with a relatively fixed number of rows, row spacing, and strip width.

[0003] To ensure the vigorous growth of corn and soybeans, weeding must be done regularly. Currently, herbicides are mostly sprayed to suppress weed growth. However, corn is a monocotyledonous plant and soybeans are a dicotyledonous plant. Therefore, the herbicides used for weeding corn and soybeans are completely different, which makes weeding corn and soybeans difficult.

[0004] For example, patent document CN220571410U discloses a weeding device for corn-soybean strip intercropping, including a support frame. A first and second pesticide tank are fixedly connected to the top of the support frame. Several first hoses are connected to the first pesticide tank, and first branch pipes are connected to the first hoses. Several first nozzles are fixedly connected to the bottom of the first branch pipes. Several second hoses are connected to the second pesticide tank, and second branch pipes are connected to the second hoses. Several second nozzles are fixedly connected to the bottom of the second branch pipes, and the second branch pipes are located between two adjacent first branch pipes. A crossbar is fixedly connected to the support frame, and several baffles are detachably connected to the crossbar. The baffles are located between adjacent first and second branch pipes. Connecting components that are detachably connected to the crossbar are installed at the top of the first and second branch pipes. The first and second branch pipes are rotatably connected to the connecting components. Positioning devices that are detachably connected to the connecting components are installed on the first and second branch pipes.

[0005] In existing technologies, when spraying herbicides, the height of soybean herbicide nozzles and corn herbicide nozzles is generally the same. However, due to the difference in height between soybean and corn plants, the spraying height of soybean pesticides is relatively high, which not only makes them easier to disperse but also weakens the herbicidal effect of the pesticides.

Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8As shown, a weeding device for corn-soybean strip intercropping includes a main body. A first lifting mechanism is provided on the front side of the main body. The first lifting mechanism includes several lifting frames 203, which are hinged to each other. A second lifting mechanism is provided on each lifting frame 203. The second lifting mechanism includes two second connecting rods 301 that are symmetrically arranged and hinged to the front side of the lifting frame 203. Another parallel second connecting rod 301 is provided on the second connecting rod 301. One end of the second connecting rod 301 is hinged to the lifting frame 203. The front ends of the two parallel second connecting rods 301 are hinged to the same spraying component 302. A power shaft 307 is rotatably connected to the middle of the lower end of the lifting frame 203. A large gear 309 is fixedly connected to one side of the power shaft 307, and a small gear 310 is fixedly connected to the second connecting rod 301 below the same side. A small gear 310 is fixedly connected to the other side of the power shaft 307, and a large gear 309 is fixedly connected to the second connecting rod 301 below the other side. 09 meshes with the small gear 310. Several lifting frames 203 are equipped with several partition plates. When it is necessary to adjust the height of the two pesticide nozzles according to the plant height, the power shaft 307 rotates. The power shaft 307 drives the large gear 309 and the small gear 310 on it to rotate synchronously. Thus, the large gear 309 on the power shaft 307 drives the small gear 310 meshing with it to rotate, and the small gear 310 on the power shaft 307 drives the large gear 309 meshing with it to rotate. Through the distribution of different transmission ratios, the rotation angle of the second connecting rod 301 is different. The rotation of the second connecting rod 301 drives the spraying component 302 to rise and fall. Thus, the relative height of the two spraying components 302 can be changed, thereby adapting to the reality that the plant heights of two adjacent planting strips are different, thereby ensuring better pesticide spraying effect. During the use of this device, the moving trolley 101 drives the device to move. The first lifting mechanism drives the spraying component 302 to rise and fall synchronously, and the second lifting mechanism realizes the differentiated height adjustment of the spraying component 302.

[0031] The first lifting mechanism includes a front support 201. Two parallel first connecting rods 202 are hinged to the front end of the front support 201 on the left and right sides respectively. A lifting frame 203 is hinged to the front end of the first connecting rods 202. First pin ears 205 are fixedly connected to the two sides of the lifting frame 203 and second pin ears 206 are fixedly connected to the two ends of the lifting frame 203. The first pin ears 205 and the second pin ears 206 on the other lifting frame 203 are connected by a pin 204. During use, the first connecting rods 202 rotate during the lifting of the lifting frame 203. The arrangement of the two parallel first connecting rods 202 ensures that the lifting frame 203 will not deflect during the lifting process. The lifting frame 203 drives the second lifting mechanism to lift. The two adjacent lifting frames 203 can be quickly disassembled and assembled through the first pin ears 205 and the second pin ears 206.

[0032] Friction clutch plates 308 are fixedly connected to both ends of the power shaft 307. Two adjacent friction clutch plates 308 can abut and transmit power. A fixed plate 303 is fixedly connected to the rear side of the intermediate lifting frame 203. A motor 304 is fixedly connected to the fixed plate 303. A drive gear 305 is fixedly connected to the output end of the motor 304. A driven gear 306 is fixedly connected to the power shaft 307. The driven gear 306 meshes with the drive gear 305. In use, when the two lifting frames 203 are connected together by a pin, the two friction clutch plates 308 abut, so power can be transmitted between the two power shafts 307. The motor 304 drives the drive gear 305 to rotate, the drive gear 305 drives the driven gear 306 to rotate, and the driven gear 306 drives the power shaft 307 to rotate.

[0033] The main body of the device includes a mobile trolley 101. The front end of the mobile trolley 101 is fixedly connected to the front bracket 201. Two pesticide tanks 102 are fixedly connected to the mobile trolley 101. An infusion tube 103 is fixedly connected to the pesticide tank 102. The infusion tube 103 extends to the front end of the mobile trolley 101 and is connected to the spraying assembly 302 through a hose. When in use, the mobile trolley 101 drives the device to move. The pesticide tanks 102 are filled with corn herbicide and soybean herbicide, respectively. The herbicide in the pesticide tanks 102 enters the spraying assembly 302 through the infusion tube 103 and the hose.

[0034] Two symmetrically arranged winches 104 are fixedly connected to the top of the mobile trolley 101. A traction rope 105 is fixedly connected to the winch 104. A symmetrically arranged traction frame 106 is fixedly connected to the top of the front end of the mobile trolley 101. The traction rope 105 is wound around the top of the traction frame 106. The other end of the traction rope 105 is fixedly connected to the lifting frame 203. The winch 104 winds up the traction rope 105, and the traction rope 105 pulls the lifting frame 203 to move. During the lifting process of the lifting frame 203, the first connecting rod 202 keeps the lifting frame 203 stable.

[0035] The partition plate includes a longitudinal support 401, and a clamping block 403 is fixedly connected to the rear side of the longitudinal support 401 by bolts. The longitudinal support 401 and the clamping block 403 can clamp and fix it to the front side of the lifting frame 203. A flexible partition plate 402 is fixedly connected to the bottom of the longitudinal support 401. In use, the partition plate is fixed by the longitudinal support 401 and the clamping block 403. When it is necessary to adjust the position of the partition plate, the bolts are loosened, and the clamping force of the longitudinal support 401 and the clamping block 403 on the lifting frame 203 is released, so the position of the partition plate can be adjusted. The partition plate is used to prevent herbicide from escaping into other planting areas.

[0036] Working principle: When the height of the two pesticide spray nozzles needs to be adjusted according to the plant height, the motor 304 drives the drive gear 305 to rotate, the drive gear 305 drives the driven gear 306 to rotate, and the driven gear 306 drives the power shaft 307 to rotate. Power is transmitted through the friction clutch plate 308, so several power shafts 307 rotate synchronously. The power shaft 307 drives the large gear 309 and the small gear 310 on it to rotate synchronously. Thus, the large gear 309 on the power shaft 307 drives the small gear 310 meshing with it to rotate, and the small gear 310 on the power shaft 307 drives... The large gear 309 meshing with it rotates, and the rotation angle of the second connecting rod 301 varies due to different transmission ratios. The rotation of the second connecting rod 301 drives the spraying component 302 to rise and fall, thus realizing the relative height change of the two spraying components 302. This adapts to the reality that the plant heights of two adjacent planting strips are different, thereby ensuring better herbicide spraying effect. During the use of this device, the moving trolley 101 drives the device to move, the first lifting mechanism drives the spraying component 302 to rise and fall synchronously, and the second lifting mechanism realizes the differentiated height adjustment of the spraying component 302.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
