Description

Technical Field

[0001] The utility model relates to the technical field of weeding equipment, and particularly relates to a handheld weeding device. Background Art

[0002] In agricultural production, especially on small plots mainly owned by farmers, small-scale weeding work is an essential part of daily maintenance. To improve weeding efficiency and reduce labor intensity, small hand-pushed weeders have gradually become a powerful assistant for farmers.

[0003] Existing small hand-pushed weeders are mainly divided into two types: electric and non-electric, each with its own unique advantages and disadvantages. Electric small hand-pushed weeders are usually equipped with lithium batteries, which have relatively high weeding efficiency and relatively low labor intensity. However, due to the addition of the lithium battery, the weight of the whole machine increases, making the operation less convenient. Especially for female and elderly users, it will be more strenuous to use for a long time. In addition, the price of electric weeders is relatively high, and the maintenance and replacement of batteries also increase the use cost. In contrast, non-electric small hand-pushed weeders have a simple structure, low price, and do not require power support, so the use cost is low.

[0004] There are also some obvious problems with the existing non-electric small hand-pushed weeders on the market. The height and angle of the blades cannot be adjusted, which limits the flexibility and efficiency of weeding. Since the height and angle of the blades are fixed and cannot be adjusted according to different grass species and terrains, this may lead to poor weeding effects in some places, increasing the workload of repeated operations and manual trimming.

[0005] Therefore, the existing technology still needs to be improved and developed. Content of the Utility Model

[0083] At present, there are also some obvious problems with the existing non-electric push-type small weeders on the market. The height and angle of the blade cannot be adjusted, which limits the flexibility and efficiency of weeding. Since the height and angle of the blade are fixed and cannot be adjusted according to different grass species and terrains, this may result in poor weeding effects in some places, increasing the workload of repeated operations and manual trimming.

[0084] Based on the above problems, see Figure 1 As shown, the present application provides a handheld weeding device, including a frame 100, a handle assembly 300, wheels 200, a slide rail 400, a housing 600, a tool rest 700 and an angle adjustment assembly 500. One end of the frame 100 forms a mounting position 140. The handle assembly 300 is arranged at the middle position of the frame 100. The wheels 200 are arranged on the frame 100 and located within the mounting position 140. The slide rail 400 is arranged on the frame 100. The housing 600 is slidably arranged on the slide rail 400. A groove 621 is arranged on the outer wall of the housing 600. The tool rest 700 is rotatably arranged in the housing 600 and at least partially extends out of the groove 621. The angle adjustment assembly 500 is arranged on the housing 600. The angle adjustment assembly 500 is connected to the tool rest 700 and is used to drive the tool rest 700 to rotate and extend out of the groove 621.

[0085] Specifically, in this embodiment, a frame 100 is disclosed. The shape of the frame 100 can be made according to the usage scenario. An installation position 140 is formed at the front end of the frame 100. The installation position 140 is used to install a wheel 200. The number of wheels 200 is set to one. The stability provided by the single wheel enables the frame 100 to work, with strong flexibility and can effectively reduce the device cost. A handle assembly 300 and a slide rail 400 are arranged at the middle position of the frame 100. The handle assembly 300 is used to facilitate the user's grip and improve the operation convenience. The slide rail 400 is slidably connected to the housing 600. The slide rail 400 is used to drive the housing 600 to slide so as to adjust the height of the tool rest 700 on the housing 600. A tool rest 700 is arranged inside the housing 600. The housing 600 is liftably arranged on the slide rail 400, which is convenient for adjusting the height of the tool rest 700 on the housing 600. An angle adjustment assembly 500 is arranged inside the housing 600. The angle adjustment assembly 500 is connected to the tool rest 700 and can drive the tool rest 700 to rotate, so as to be able to adjust the angle of the tool rest 700. The height and angle of the tool rest 700 are adjusted through a simple structure, which is more convenient to use and can be flexibly adjusted according to different grass species and terrains, significantly improving the working efficiency of weeding.

[0086] Furthermore, the frame 100, the handle assembly 300, and the slide rail 400 are all made of lightweight metal materials or lightweight plastic materials, such as metal materials like aluminum alloy and stainless steel, and such as plastic materials like acrylonitrile-butadiene-styrene copolymer (ABS), etc. Preferably, in this application, the frame 100, the handle assembly 300, and the slide rail 400 made of aluminum alloy make the device durable, lightweight, easy to operate and carry, enabling the user to easily maintain an efficient working state.

[0087] See Figure 3 and Figure 4As shown, in another embodiment of the present application, the angle adjustment assembly 500 includes a driving gear 501, a pull handle 504, a bracket 506, a locking gear 502, and a locking spring 503. The driving gear 501 is rotatably disposed within the housing 600 and is fixedly connected to the tool rest 700. The pull handle 504 is inserted through the housing 600 and extends into the housing 600. The bracket 506 is disposed at one end of the pull handle 504 within the housing 600 and is connected to the driving gear 501. The locking gear 502 is disposed on the bracket 506 and is located within the housing 600. The locking gear 502 is located above the driving gear 501. One end of the locking spring 503 is fixedly connected to the inner wall of the housing 600, and the other end is connected to the bracket 506. Wherein, the elastic force of the locking spring 503 drives the bracket 506 to move towards the driving gear 501, and the locking gear 502 meshes with the driving gear 501 to lock the driving gear 501.

[0088] Specifically, the specific structure of the angle adjustment assembly 500 is disclosed in this embodiment. When the user pulls up the pull handle 504, the pull handle 504 drives the bracket 506 to move upward. The locking gear 502 on the bracket 506 moves upward, causing the locking gear 502 and the driving gear 501 to disengage and separate. The user can rotate the tool rest 700 on the driving gear 501 to facilitate adjusting the angle of the tool rest 700. At the same time, the locking spring 503 is compressed to store elastic potential energy. When the user releases the pull handle 504, the elastic potential energy of the locking spring 503 is released, driving the bracket 506 to move downward. The locking gear 502 is located above the driving gear 501, and the locking gear 502 meshes with the driving gear 501 to lock the tool rest 700. In the present application, by using gear transmission to set the angle adjustment assembly 500, the structure is compact, occupies a small space, is convenient for replacement and maintenance, and can effectively reduce the cost of the device.

[0089] Further, the bracket 506 is a U-shaped bracket 506. Depressions at both ends of the U-shaped bracket 506 form a first end and a second end, enabling the locking gear 502 to be connected to the U-shaped bracket 506.

[0090] Further, the tool rest 700 is fixed on the second rotating shaft 505, and the second rotating shaft 505 is also rotatably connected to the housing 600, such that the tool rest 700 rotates as the second rotating shaft 505 rotates. The driving gear 501 is disposed on the second rotating shaft 505, and the driving gear 501, the second rotating shaft 505, and the tool rest 700 are integrally formed, enhancing the structural strength and extending the service life of the components.

[0091] Furthermore, the tool holder 700 includes a connecting rod 710, a reinforcing rib 720 and a blade 730. One end of the connecting rod 710 is arranged on the driving gear 501, and the blade 730 is arranged on the other end of the connecting rod 710. The reinforcing rib 720 is arranged on the connecting rod 710, and the reinforcing rib 720 is used to fix the blade 730, so that the connection between the blade 730 and the connecting rod 710 is more secure. The tool holder 700 is arranged by a simple structure, which is convenient for maintenance and replacement.

[0092] Furthermore, the housing 600 is provided with scales, which are arranged on the outer wall of the housing 600 along the periphery of the second rotating shaft 505, such as 30°, 40°, 50°, etc., so that the user can clearly understand the angle of the tool holder 700.

[0093] See also Figure 3 and Figure 4 As shown, in another embodiment of the present application, a plurality of lifting screw holes 401 are provided on the slide rail 400 , and a lifting bolt 420 is provided on the slide rail 400 . The lifting bolt 420 passes through the lifting screw holes 401 and the shell 600 to fix the shell 600 on the slide rail 400 .

[0094] Specifically, the slide rail 400 is in the shape of a rectangular parallelepiped and is located in the middle of the frame 100. An extension rod 410 is arranged on the slide rail 400, and the extension rod 410 is used to extend the position of the slide rail 400, so that the slide rail 400 is not easy to conflict with the frame 100; a slide groove is arranged on the slide rail 400, and one end of the shell 600 is slidably connected to the slide groove, and a plurality of lifting screw holes 401 are arranged on the slide rail 400, and the intervals between two adjacent lifting screw holes 401 are equal, so that each lifting screw hole 401 corresponds to a height, and the height of the shell 600 is adjusted by adopting a bolt locking method, and then the height of the tool holder 700 on the shell 600 is adjusted, so that the height of the tool holder 700 is precisely controlled, the assembly and maintenance are convenient, and the height of weeding can be flexibly adjusted.

[0095] See also Figure 2 and Figure 3 As shown, the handheld weeding device also includes a rotating sleeve 910 and a first rotating shaft 920. The rotating sleeve 910 is arranged in the middle position of the frame 100 and is connected to the slide rail 400. The first rotating shaft 920 is sleeved on the rotating sleeve 910. Both ends of the first rotating shaft 920 extend to a side away from the rotating sleeve 910. Both ends of the first rotating shaft 920 are cut to form two flat surfaces. The handle assembly 300 is arranged on the two flat surfaces, wherein at least one elastic damper 921 is provided on the first rotating shaft 920, and a plurality of recessed portions are arranged along the periphery of the rotating sleeve 910. The recessed portions are adapted to the elastic damper 921, and the elastic damper 921 is engaged and connected with the recessed portions.

[0096] Specifically, the rotating sleeve 910 is installed at the exact middle position on the top of the frame 100. A first rotating shaft 920 is sleeved on the rotating sleeve 910. Both ends of the first rotating shaft 920 extend out of the rotating sleeve 910, and flat portions 922 are formed by cutting at both ends, which is convenient for installing the handle assembly 300. A number of recessed portions are arranged along the periphery of the rotating sleeve 910. An elastic damper 921 is arranged on the first rotating shaft 920. When the user rotates the first rotating shaft 920, the elastic damper 921 of the first rotating shaft 920 deforms and compresses to rotate into the recessed portion corresponding to its position, so as to achieve the self-locking effect of the first rotating shaft 920, and further lock the rotation angle of the handle assembly 300. In this application, by using the damping self-locking method to lock the first rotating shaft 920, the rotation is relatively smooth and it is more convenient for the user to use. Moreover, by arranging the rotatable handle assembly 300, the needs of different users are met.

[0097] Further, the elastic damper 921 is a damper made of an elastic material, such as rubber, polypropylene, etc.; preferably, four elastic dampers 921 are arranged on the first rotating shaft 920, and the angle between each elastic damper 921 is 90°. A number of recessed portions are arranged inside the rotating sleeve 910, so that the cooperation between the elastic damper 921 and the recessed portion is more firm and reliable.

[0098] Further, since the rotating sleeve 910 has a certain height and the rotating sleeve 910 is arranged in the exact middle of the frame 100, at this time, the user can rotate the handle assembly 300 to the side close to the wheel 200 and then push the device, or rotate the handle assembly 300 to the side close to the slide rail 400 and then push the device. That is to say, the device can be pushed on the left or on the right, making the operation of the device more flexible.

[0099] Further, the width between the two flat portions 922 is greater than the width of the wheel 200, so that the handle assembly 300 can be rotated to a lower position and is not likely to conflict with the wheel 200.

[0100] See Figures 6 to 10As shown, in another embodiment of the present application, the handle assembly 300 includes two first pull rods 302, two second pull rods 301, a handle 303, two sliders 305, and a pulling-back component. The two first pull rods 302 are arranged at both ends of the first rotating shaft 920. A plurality of card slots 3011 are provided on each of the two first pull rods 302. The two second pull rods 301 are sleeved inside the two first pull rods 302. The handle 303 is arranged on the two second pull rods 301. A placement groove is provided at the middle position of the handle 303. A slidable button 304 is arranged on the placement groove. The two sliders 305 are slidably arranged inside the two second pull rods 301. A clamping block 306 is arranged at one end of the slider 305. The clamping block 306 is used to pass through the second pull rod 301 and be clamped into the card slot 3011. A first spring 312 is arranged at the other end of the slider 305. The other end of the first spring 312 is fixedly connected to the inner wall of the second pull rod 301. One end of the pulling-back component is connected to the button 304, and the other end is connected to the slider 305. Wherein, when an external force acts on the button 304, the button 304 drives the two sliders 305 to move in the direction close to the first spring 312 through the pulling-back component. The first spring 312 is compressed to store elastic potential energy. The two clamping blocks 306 are disengaged from the two card slots 3011, and the two second pull rods 301 can slide inside the two first pull rods 302.

[0101] Specifically, the specific structure of the handle assembly 300 is disclosed in this embodiment. The handle assembly 300 includes two first pull rods 302, two second pull rods 301, a handle 303, two sliders 305, and a pulling-back component. The button 304 is installed at the exact middle position of the handle 303 and is located on the placement groove. The user first grabs the handle with one hand and then uses a finger, such as the thumb, to press the button 304. The button 304 moves downward under the external force. One end of the button 304 is connected to the pulling-back component, and the other end of the pulling-back component is connected to the slider 305. Thus, the slider 305 can be driven to move in the direction close to the first spring 312 through the pulling-back component. The clamping block 306 on the slider 305 can be away from the card slot 3011 on the first pull rod 302, and the second pull rod 301 can slide smoothly inside the first pull rod 302, enabling the user to adjust the length of the handle assembly 300 with one hand, which is convenient, fast, and easy to operate.
