Description

Technical Field

[0001] The utility model relates to the technical field of cultivated land weeding, in particular to a splicable weeder for planting Codonopsis pilosula. Background Art

[0002] When planting Chinese medicinal materials, they not only need to be watered and cultivated on time, but also need to be weeded during planting. Using a weeder to weed in the planting of Chinese medicinal materials can save the working time of weeders and reduce a lot of human resources.

[0003] Prior art publication number CN220755536U discloses a lawn mower comprising a carrier plate, a blade, and a drive structure. The bottom of the carrier plate is rotatably connected to a rotating shaft, the drive structure is used to drive the rotating shaft, and the blade is detachably mounted on the rotating shaft. A splash guard is mounted on the bottom of the carrier plate, and U-shaped seats are equidistantly mounted on the outside of the splash guard. Slideways are provided at the top and bottom of the inner wall of the U-shaped seat, and sliders are slidably connected to the interior of the slideways. A protective wheel rotates between the two sliders, and a buffer spring is fixed between the inner wall of the slideway and the slider. This lawn mower, by providing protective wheels around the splash guard and working in conjunction with the buffer spring, can provide buffering protection when the device contacts slightly larger gravel or hard objects on the ground, thereby preventing the blade from directly contacting the gravel or hard objects, thereby achieving the purpose of protecting the blade and facilitating practical application and operation.

[0004] However, the patents under the existing technology have the following disadvantages:

[0005] (1) The blade height of the lawn mower of this utility model is fixed, and it is impossible to ensure that the blade maintains an appropriate distance from the ground. When operating on uneven ground, it is very easy for the blade to directly collide with the ground or hidden hard objects, which may not only damage the blade and shorten the service life of the machine, but also pose a safety hazard to the operator due to the sudden impact force.

[0006] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0033] The weeding assembly 7 includes a motor 2 701, a driving pulley 702, a driven pulley 703, a connecting pipe 705, a slide rod 706, a rotating drum 707, a mounting shaft 708 and a weeding knife group 709. The motor 2 701 is fixedly connected to the rear side of the bottom end of the working box 1, the driving pulley 702 is fixedly connected to the output end of the upper end of the motor 2 701, the driven pulley 703 is sleeved on the outside of the support pipe 605, and the driving pulley 702 and the driven pulley 703 are connected by a transmission belt 704, which is sleeved on the driving pulley 702 and the driven pulley 709. 03 are on the side away from each other, two connecting tubes 705 are fixedly connected to the front and rear ends of the bottom ends of the driven pulley 703, the sliding rod 706 is inserted into the connecting tube 705, the bottom end of the rotating drum 707 is fixedly connected to the bottom end of the rotating shaft 3 610, the lower end of the sliding rod 706 is fixedly connected to the lower end of the inner part of the rotating drum 707, the rotating drum 707 is slidably connected to the working slot hole 5, the lower end of the rotating drum 707 extends through the inside of the working slot hole 5 to the lower side of the outside of the working box 1, the mounting shaft 708 is fixedly connected to the middle of the bottom end of the outer side of the rotating drum 707, and the weeding knife group 709 is locked to the lower end of the mounting shaft 708 by a nut;

[0034] The telescopic rod assembly 8 includes a telescopic tube 801 and a telescopic rod 802. The telescopic tube 801 is locked and connected to the outer rear side of the working box 1 by a nut. The telescopic rod 802 is inserted into the telescopic tube 801. The telescopic rod 802 is locked with the telescopic tube 801 by a locking assembly 9. The top of the telescopic rod 802 is fixedly connected to a handle 10, and the outside of the telescopic rod 802 is fixedly connected to an auxiliary handle 11.

[0035] The locking assembly 9 includes a locking knob 1 901, a locking plate 902 and a locking knob 2 903. The locking knob 1 901 is fixedly connected to the top of the telescopic tube 801. Several locking plates 902 are fixedly connected to the upper end of the locking knob 1 901. The outer diameter of the locking plates 902 gradually increases from top to bottom.

[0037] Start motor 1 601, motor 1 601 drives bevel gear 1 602 to rotate, and bevel gear 1 602 drives rotating shaft 2 603 to rotate. Since the outer limit bar 609 of sleeve 608 is slidably connected to the limit groove 606 on the inner wall of support tube 605, sleeve 608 will not rotate with rotating shaft 2 603. Sleeve 608 rises or falls with the rotation of rotating shaft 2 603, and sleeve 608 drives slide bar 706 to slide up and down in connecting tube 705. Sleeve 608 and slide bar 706 drive rotating drum 707 to rise or fall, and rotating drum 707 drives weeding knife group 709 to rise or fall, thereby adjusting the safe distance between blade and ground, avoiding direct contact between blade and ground or other hidden hard objects, reducing wear and damage of blade, and thus extending the service life of the weeder.

[0038] Start motor 2 701, which drives the active pulley 702 to rotate. The active pulley 702 drives the driven pulley 703 to rotate through the transmission belt 704. The driven pulley 703 drives the connecting pipe 705 and the sliding rod 706 to rotate. The connecting pipe 705 and the sliding rod 706 drive the rotating drum 707 and the rotating shaft 3 610 to rotate. The rotating drum 707 drives the weeding knife group 709 to rotate, thereby realizing the weeding function.

[0039] When the weeding knife group 709 needs to be replaced or sharpened, loosen the nut and remove the weeding knife group 709 from the mounting shaft 708, and lock the replaced weeding knife group 709 to the mounting shaft 708 through the nut. The telescopic tube 801 and the baffle 12 can be disassembled and spliced by loosening or tightening the nut, which is convenient for carrying and easy to operate.

[0040] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components.
