Description
Technical Field
[0001] The utility model relates to the field of gardening tools, in particular to a simple weeder with a weed removal mechanism. Background Art
[0002] Traditional manual weeding methods are time-consuming and laborious, and are prone to damaging the soil and surrounding vegetation. Most of the existing weeding tools on the market focus on enhancing the gripping force or the cutting effect of the blade, but the treatment of weeds after pulling out is not convenient. Users often need to manually clean the weeds on the tool, which affects the work efficiency. Therefore, it is of practical significance to develop a weeder that can remove weeds.
[0003] The simple weeders on the current market generally adopt a four-claw eccentric hinge design, which often leads to poor balance of the tool during the weeding process, affecting the weeding efficiency and the user experience. In addition, due to the small size of the pedal, the foot force is uneven, increasing the physical consumption of the operator, and after completing the weeding action, it is usually necessary to manually remove the weeds, further reducing the work efficiency. Summary of the Invention
[0004] The utility model provides a simple weeder with a weed removal mechanism, which avoids manually cleaning the weeds on the tool by designing a weed removal mechanism, improving the work efficiency; at the same time, the central hinge is improved to improve the overall balance of the device; the design of the segmented handle optimizes the use experience of different people.
[0005] The utility model provides a simple weeder with a weed removal mechanism, which comprises:
[0006] A rod body;
[0007] A clamping mechanism at one end of the rod body, including an openable and closable claw assembly and a claw assembly controller;
[0008] A weed removal mechanism, including a weed removal core rod arranged in the rod body, a return elastic element connected to one end of the weed removal core rod, and a weed removal handle sleeve connected to the end of the return elastic element. The end of the weed removal core rod far from the weed removal handle sleeve is hinged to the openable and closable claw assembly.
[0009] By adding a weed removal mechanism to the traditional claw assembly, it is avoided that the user needs to manually clean the weeds on the tool during use, improving the work efficiency.
[0010] Preferably, the return elastic element is a return spring, which is low in cost and saves costs.
[0011] Preferably, the claw assembly controller is a pedal, which is convenient for workers to operate and saves operation steps.
[0012] Preferably, the pedal is a widened pedal with a width of 10-15 cm, which expands the foot force application area, disperses the weight pressure of the user, reduces foot fatigue, and improves the operation comfort.
[0013] The claw assembly includes a main claw, and a sub-claw is hinged on the surface of the main claw. The hinged manner between the main claw and the sub-claw is central hinging. Compared with eccentric hinging, the advantage of the central hinging connection method is that it enhances the stability and balance during weeding, makes the insertion and extraction actions of the four claws in the soil smoother, reduces lateral offset, and improves the weeding efficiency.
[0014] One end of the grass-receding mandrel penetrates through the claw assembly, making the operation of the grass-receding mandrel more convenient.
[0015] The connection part of the segmented handle is fixed by a fixed clip, which is convenient for adjusting different lengths to meet the needs of different people.
[0016] Preferably, the length of one section of the segmented handle is 40 cm.
[0017] One end of the grass-receding mandrel is fixed inside the segmented handle, and the push-back elastic element is located inside the segmented handle, which is convenient for use and reduces the complexity of the work.
[0018] Preferably, a handle cap is connected to one end of the segmented handle far from the grass-receding grip that is far from the grass-receding grip, improving the safety of the worker during operation.
[0019] The hinged part between the main claw and the sub-claw is connected to the claw assembly controller, so that the opening and closing of the claw assembly are synchronized with the movement of the claw assembly controller, which is convenient for pushing out weeds during use.
[0020] One end of the push-back elastic element far from the grasping and clamping mechanism is connected to the middle position inside the grass-receding grip. The grass-receding grip is arranged outside the segmented handle, and the connection is smoother when pushing down the grass-receding grip.
[0021] Preferably, the position of the grass-receding grip is 70-80 cm from the top of the claw assembly, which can meet the needs of the vast majority of people.
[0022] The diameters of the two ends of the segmented handle are different. The two sections of the segmented handle are inserted and fixed front and back, and then fixed with a fixed clip, which can improve the stability of the whole structure.
[0023] The main claw has two claws, and the sub-claw has two claws. The four-claw structure can grasp weeds more firmly.
[0024] Compared with the prior art, the beneficial effects of the present utility model are:
[0025] 1. Change the traditional four - claw eccentric hinge to a central hinge structure, enhancing the stability and balance during weeding, making the insertion and extraction actions of the four claws in the soil smoother, reducing lateral offset, and improving weeding efficiency.
[0026] 2. Increase the pedal size to twice the original design, expanding the foot - pressing force - exerting area, dispersing the weight pressure of the user, reducing foot fatigue, and improving operation comfort.
[0027] 3. Add a weed - removing core rod at the center of the four claws and install a return spring on the core rod. Add a weed - removing grip on the handle tube. The user only needs to gently push down the grip, and through the thrust of the front - end weed - removing claws, the weeds can be easily pushed out of the four claws, greatly simplifying the weed - removing process and improving work efficiency.
[0028] 4. Adopt a multi - section handle tube design with adjustable length, fixed with fastening clips. According to the user's height and work requirements, the handle length can be flexibly adjusted to meet the usage needs in different scenarios, further enhancing the versatility and convenience of the tool.
