Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a soybean weeding device for post-smoking intercropping. Background Art

[0002] In addition to the crops that farmers intentionally cultivate, weeds also abound in crop fields. These weeds pose numerous risks, such as competing for nutrients, water, and sunlight; hindering field ventilation and light penetration; and promoting the occurrence of pests and diseases. Weeds directly or indirectly affect crop growth, severely impacting yield, quality, and quality.

[0003] Currently, weed control in farmland usually involves manual weeding, mechanical weeding, biological control, and chemical weed control. For large-scale planting fields, weed control equipment is often used for weed control, but existing weed control equipment does not completely control weeds.

[0004] For example, the patent with publication number CN 106961913A specifically discloses a weeding device that performs weeding operations by means of a horizontally rotating blade. When this device is used to weed soybeans interplanted after tobacco, the distance between adjacent soybean plants is small, so the blade cannot extend into the space between the soybean plants. Otherwise, the soybean plants will also be removed, resulting in the weeds between the soybean plants not being effectively removed, and the weeding equipment not being able to weed completely. Summary of the Invention

[0031] The invention aims to solve the technical problem that existing weeding equipment cannot effectively remove weeds between adjacent crop plants.

[0032] See also Figure 1 and Figure 2 The present application provides a soybean weeding device for intercropping after tobacco, comprising a transmission box 1, a weeding roller 2, a first drive motor 3, a second drive motor 4, and a connecting frame 5.

[0033] The transmission box 1 is in the shape of a hollow cylinder with an open top and a closed bottom. Weeding rollers 2 are arranged on the circumferential surface of the transmission box 1 at intervals around its circumferential direction. The weeding rollers 2 are rotatably connected to the transmission box 1 through bearings, and one end of the weeding roller 2 extends into the transmission box 1 along the radial direction of the transmission box 1. Rake nails 21 are arranged at intervals on the outer circumferential surface of the weeding roller 2.

[0034] During weeding operations, one of the weeding rollers 2 extends between adjacent crop plants and rotates continuously, thereby removing weeds on the ground through the rake spikes 21, thereby achieving the purpose of removing weeds between adjacent crop plants; other weeding rollers 2 rotate between the soybean rows to perform weeding operations between the soybean rows, thereby ensuring that weeds in all positions can be removed, and the weed removal is more thorough; by installing the weeding device on an agricultural machinery vehicle, the agricultural machinery vehicle drives the weeding device to move forward continuously, and the transmission box 1 itself also rotates relatively, thereby continuously extending the weeding rollers 2 between adjacent crop plants for weeding operations, as long as the rotation speed of the transmission box 1 itself, the travel speed of the agricultural machinery vehicle and the interval between the crops match, continuous weed removal can be achieved.

[0035] In this embodiment, a connecting frame 5 is connected to external agricultural machinery and serves as the mounting base for the entire weeding device. The connecting frame 5 is positioned above the transmission case 1 and is movably connected to the transmission case 1. Specifically, a vertically downwardly extending rotatable connection portion 51 is provided in the middle of the connecting frame 5. This rotatable connection portion 51 extends into the transmission case 1 and is rotatably connected to the transmission case 1 via a bearing, thereby enabling the transmission case 1 to rotate.

[0036] In this embodiment, an outer ring gear 12 is provided on the outer circumferential surface of the transmission box 1 and is located above the weeding roller 2. A second drive motor 4 is provided on the connecting frame 5. A third gear is provided on the output shaft of the second drive motor 4. The third gear is engaged with the outer ring gear 12, so that the output shaft of the second drive motor 4 is connected to the outer ring gear 12 through the third gear. The second drive motor 4 adopts a stepping motor or a servo motor. When the second drive mechanism motor is energized and rotated, the transmission box 1 is driven to rotate through the outer ring gear 12.

[0037] In this embodiment, a first drive motor 3 is provided on the connecting frame 5, and the output shaft of the first drive motor 3 passes through the connecting frame 5 and extends downward into the transmission box 1. A first gear is provided at the end of the output shaft of the first drive motor 3, and a second gear is provided at one end of each weeding roller 2 extending into the transmission box 1. The first gear is engaged with the second gear, thereby connecting the output shaft of the first drive motor 3 to the gear transmission of the weeding roller 2; the first drive motor 3 is a stepping motor or a servo motor. When the first drive motor 3 is powered on and rotated, it drives all the weeding rollers 2 to rotate synchronously to perform weeding operations.

[0038] In some specific embodiments, the transmission case 1 is constructed with a first connecting portion 11 extending radially from its inner side surface. The first connecting portion 11 is located between the weeding roller 2 and the rotating connecting portion 51. The output shaft of the first drive motor 3 is rotationally connected to the first connecting portion 11 via a bearing. In this manner, the upper end of the output shaft of the first drive motor 3 is restrained by its own bearing, and the lower end of the output shaft of the first drive motor 3 is also restrained by a bearing. Consequently, bearings restrain both the upper and lower ends of the output end of the first drive motor 3, thereby reducing vibration at the output end of the first drive motor 3, ensuring smoother transmission, and reducing the risk of damage to the first drive motor 3.

[0039] In some specific embodiments, the connecting frame 5 is provided with a second connecting portion 52 extending vertically upward, and the second drive motor 4 is fixedly mounted on the second connecting portion 52; the second connecting portion 52 is also provided with a connecting hole 53, which is used to connect to external agricultural machinery and equipment.

[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, the transmission box 1 is provided with a protective cover 6 covering the weeding roller 2. The protective cover 6 effectively covers the top of the weeding roller 2. In this way, when the weeding roller 2 extends between adjacent plants to weed, the leaves on the plants will not touch the weeding roller 2, thereby effectively avoiding the problem of mistakenly removing crop plants.

[0041] In this embodiment, the protective cover 6 is provided with a mud-pushing rod 61 extending toward the interior thereof. The mud-pushing rod 61 is arranged at an angle and is staggered with the rake nails 21 on the weeding roller 2. In this way, when the rake nails 21 on the weeding roller 2 pass through the mud-pushing rod 61, the mud-pushing rod 61 pushes outwards to remove the weeds entangled on the rake nails 21, effectively ensuring the smooth progress of the weeding process.

[0042] In some specific embodiments, the connecting frame 5 is provided with a camera 7 for detecting the spacing between crop plants. The camera 7 is connected to the signal input end of the controller, and the signal output end of the controller is electrically connected to the second drive motor 4. When in use, the controller is connected to external agricultural machinery and equipment to obtain the travel speed of the agricultural machinery and equipment. At the same time, the camera 7 takes pictures of the crops and uses its own image recognition software to obtain the spacing between crop plants and transmits the relevant data to the controller. The controller controls the speed of the second drive motor 4 according to the input data, effectively ensuring that the weeding roller 2 can be accurately inserted between adjacent plants for weeding.

[0043] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
