Description

A multi-functional farmland weeding tool Technical Field

[0001] This utility model relates to the field of aluminum anti-counterfeiting detection technology, specifically a multifunctional farmland weeding tool. Background Technology

[0002] In agricultural production, weeding and hoeing are two crucial and frequently performed agricultural operations. Traditional weeding methods rely heavily on manual labor using tools such as hoes and sickles. This method is not only extremely labor-intensive but also inefficient, making it difficult to meet the weeding needs of large-scale farmland. Furthermore, during manual weeding, it is difficult to maintain consistent pressure and depth, leading to incomplete weed removal and rapid regrowth, which negatively impacts crop growth and yield.

[0003] Utility model patent CN221863621U discloses an agricultural weeding device, including an upper support pipe, an upper cross brace pipe, a lower branch pipe, a lower cross brace pipe, a speed regulator, a diesel engine, a throttle adjustment pipe, a multi-functional protective cover assembly, a weeding and shredding cage assembly, an anti-slip rubber sleeve, a throttle adjustment handle, a buffer pad, a refueling pipe, wheels, and a power rod. The device allows users to adjust the diesel engine's power output by manually holding the throttle adjustment handle, enabling power adjustments as needed during weeding. Furthermore, when the scraper blades and weeding blades are covered in dirt, the user can stop the machine and remove the cleaning scraper from the storage housing to remove the dirt. The device is also equipped with a lubricating oil can for convenient regular lubrication and maintenance, thereby improving work efficiency and extending service life.

[0004] However, the angle and extension of the blades in this existing technology are fixed, making it impossible to flexibly adjust according to different farmland environments, crop types, and weed growth conditions. This results in poor weeding effectiveness and may even damage crops. Furthermore, this weeding equipment is single-function, requiring farmers to use other specialized equipment for hoeing after weeding. This not only increases agricultural production costs but also wastes resources and reduces agricultural efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides the following technical solution: A multifunctional farmland weeding tool, comprising a weeding section and a supporting section; the weeding section includes a weeding blade, which is rotatably mounted on a weeding slider and slidably mounted on a weeding adjusting ring; the weeding slider is slidably mounted on a weeding roller; the weeding adjusting ring is rotatably mounted on the weeding roller, and its position is limited by a weeding limiting knob to adjust the tilt angle of the weeding blade; the weeding blade slides in conjunction with a weeding adjusting ring fixedly mounted on a weeding adjusting shaft to adjust the extension amount of the weeding blade; a weeding groove wheel is fixedly mounted on the weeding roller, and the weeding groove wheel is connected to a weeding transmission shaft via a weeding transmission belt; the weeding transmission shaft is fixedly mounted on the output shaft of a weeding motor; the supporting section includes a supporting bracket, and the weeding transmission shaft and the weeding groove wheel are both rotatably mounted on the supporting bracket, with a supporting handle rotatably mounted on the supporting bracket.

[0034] As shown in Figures 1 to 14, the working principle of this utility model is as follows:

[0035] During weeding, the operator first loosens the weeding fixing nut 108 to disconnect it from the weeding roller 104. The operator then manually rotates the weeding adjustment handle 109, which drives the weeding adjustment shaft 110 to rotate. The rotation of the weeding adjustment shaft 110 drives the weeding adjustment ring 107 to rotate, which in turn drives the weeding blade 101 to slide on the weeding adjustment ring 102. During this process, the weeding slider 106 slides along with the weeding blade 101, adjusting the extension of the weeding blade 101 in the radial direction of the weeding roller 104 so that the weeding blade 101 can cut the grass roots. Then, the weeding fixing nut 108 is reset to fix the weeding adjustment shaft 110 and the weeding roller 104, thereby fixing the position of the weeding blade 101. After the extension of the weeding blade 101 is adjusted, the weeding motor 111 is turned on.

[0036] The weeding motor 111 starts, driving the weeding drive shaft 112 to rotate. The rotation of the weeding drive shaft 112, through the weeding drive belt 113, drives the weeding groove wheel 105 to rotate. The rotation of the weeding groove wheel 105 drives the weeding roller 104, the weeding limit knob 103, the weeding adjustment ring 102, the weeding slider 106, the weeding blade 101, the weeding adjustment shaft 110, the weeding adjustment handle 109, the weeding adjustment ring 107, and the weeding fixing nut 108 to rotate together. The operator pushes the support part 2 and the weeding part 1 to move by the support handle 201, and the rotating weeding blade 101 removes the grass on the ground, thus completing the weeding operation.

[0037] When hoeing, the operator first turns the weeding limit knob 103 to disengage it from the limiting hole on the weeding adjustment ring 102. Then, the operator rotates the weeding adjustment ring 102, causing the weeding blade 101 to deflect along the position where it is rotatably connected to the weeding slider 106. After adjusting the position of the weeding blade 101, the operator resets the weeding limit knob 103 to again limit the position of the weeding adjustment ring 102 and the weeding blade 101. Simultaneously, depending on the required hoeing depth, the operator first turns the weeding fixing nut 108 to loosen it from the weeding roller 104. The operator then manually... Rotate the weeding adjustment handle 109, which drives the weeding adjustment shaft 110 to rotate. The rotation of the weeding adjustment shaft 110 drives the weeding adjustment ring 107 to rotate, and the rotation of the weeding adjustment ring 107 drives the weeding blade 101 to slide on the weeding adjustment ring 102. During this process, the weeding slider 106 slides together with the weeding blade 101, adjusting the extension amount of the weeding blade 101 in the radial direction of the weeding roller 104 so that the weeding blade 101 can meet the needs of weeding at different depths. Then, reset the weeding fixing nut 108 to fix the weeding adjustment shaft 110 and the weeding roller 104, thereby fixing the position of the weeding blade 101. The adjustment of the extension amount of the weeding blade 101 is completed.

[0038] When the weeding motor 111 is turned on, it drives the weeding drive shaft 112 to rotate. The rotation of the weeding drive shaft 112, through the weeding drive belt 113, drives the weeding groove wheel 105 to rotate. The rotation of the weeding groove wheel 105 drives the weeding roller 104, the weeding limit knob 103, the weeding adjustment ring 102, the weeding slider 106, the weeding blade 101, the weeding adjustment shaft 110, the weeding adjustment handle 109, the weeding adjustment ring 107, and the weeding fixing nut 108 to rotate together. The operator pushes the support part 2 and the weeding part 1 to move by pushing the support handle 201, and the rotating weeding blade 101 performs weeding operations on the ground, realizing multiple uses of one machine.
