Description

Technical Field

[0001] The utility model relates to the field of weeders, in particular to a small garden weeder. Background Technique

[0002] After the construction of a garden park, due to the irregular growth of herbaceous plants and to improve the ornamental value of the garden, it is necessary to regularly prune the herbaceous plants. To improve the efficiency of pruning herbaceous plants, a weeder is usually used to complete the weeding task. At present, there are many types of weeders. For example, a field weeder and a weeding method disclosed in a Chinese patent with the publication number CN111955068B. The weeder includes a power chassis, a lifting hydraulic cylinder, a parallelogram suspension, a weeding machine frame, a transmission assembly, and a weeding unit. The power chassis is connected to the weeding machine frame through the parallelogram suspension and is connected to the parallelogram suspension through the lifting hydraulic cylinder for vertically adjusting the working depth of the weeder. The transmission assembly transmits the power of the power chassis to the weeding unit through chain drive. There are 4-8 groups of grass collection reverse teeth distributed on the grass collection spiral of the weeding unit, and the reverse tooth angle is 50-70° for pulling out weeds between rows and feeding them into the grass crushing channel. The spiral grass cutter includes 6-10 groups of cutter teeth, and the cutter teeth are in a spiral structure for crushing weeds and conveying them to the feeding channel. The two-way variable pitch auger includes 2 groups of variable pitch spiral augers rotating in opposite directions, which pressurize and convey the crushed grass to the discharge port of the feeding channel and then discharge it for burying weeds between plants. Although the weeder provided by this patent can complete the weeding task, due to its large size, it is inconvenient to remove herbaceous plants in a garden with a complex environment, and it is even more unfavorable for cleaning herbaceous plants in the garden river.

[0003] To solve the above problems, some smaller and lighter weeders have emerged on the market. For example, a weeder disclosed in a Chinese patent with the publication number CN103404296A includes a long rod-shaped body. One end of the body is provided with a driving unit, and the other end is provided with a transmission system. The body is hollow, and a driving rod connects the driving unit and the transmission system. The end of the transmission system is fixed with a rotatable circular blade, and a semi-circular shield is fixed behind the circular blade; one end of the driving rod passing through the body is rotatably fixed in the body through a ball bearing, and a driving bevel gear is fixed at the end of the driving rod; a transmission rod is arranged in the housing of the transmission system, and a transmission bevel gear meshing with the driving bevel gear is fixed on the transmission rod. The weeder provided by this patent can be carried on the back of a staff member. Therefore, it can adjust its own position as the staff member moves, providing convenience for weeding in a garden with a complex environment.

[0004] However, the body of the weeding machine provided by the patent with the publication number CN103404296A is too long and the body is not detachable and assembled. Therefore, the weeding machine is relatively long, which is inconvenient for the staff to place on a bicycle or a tricycle for transportation. Since the weeding machine always protrudes from the transport vehicle, it affects the driving of other vehicles when the transport vehicle is moving. In addition, when the staff carry the weeding machine on their backs, the body fits against the staff's waist and squeezes the staff's waist at the same time, resulting in waist pain for the staff after a long time.

[0027] The following will be further described in conjunction with the drawings and specific embodiments:

[0028] Embodiment 1

[0029] In the background technology, it is described that the existing weeding machine cannot be disassembled and folded, so its length is fixed, which is inconvenient for the staff to transport it by bicycle or tricycle. And when using the weeding machine, the weeding machine presses the waist of the user, causing pain. To solve the above problems, in this embodiment, a new weeding machine is obtained by improving the existing weeding machine. The specific scheme of this weeding machine is as follows.

[0030] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the weeding machine includes an engine 6, a harness 4, a first pipe body 1, a second pipe body 2, and a weeding mechanism 7. The first pipe body 1 and the second pipe body 2 are arranged end to end. A first transmission rod 13 and a second transmission rod 22 are respectively arranged in the first pipe body 1 and the second pipe body 2. The first transmission rod 13 and the second transmission rod 22 are connected by bearings 23 and are respectively arranged in the first pipe body 1 and the second pipe body 2. The ends of the first transmission rod 13 and the second transmission rod 22 that are close to each other are inserted and connected. The engine 6 is arranged at the top of the second pipe body 2, and the second connecting plate 21 at the top of the second pipe body 2 is connected to the engine 6. The weeding mechanism 7 is arranged at the bottom of the first pipe body 1. Therefore, when the engine 6 is started, the first transmission rod 13 and the second transmission rod 22 can be controlled to rotate synchronously through the operation of the engine 6, thereby driving the weeding mechanism 7 to work. The structure of the engine 6 can be the drive unit provided by the patent with the publication number CN103404296A, or it can be set as a gasoline engine 6. In short, the weeding mechanism 7 can be controlled to work. The weeding mechanism 7 can be composed of the transmission system and the circular blade provided by the patent with the publication number CN103404296A. Since the drive unit, the transmission system, and the circular blade have all been disclosed, they will not be elaborated here in detail. By setting the first pipe body 1 and the second pipe body 2, the first transmission rod 13 and the second transmission rod 22, on the premise of meeting power transmission and supporting the weeding mechanism 7, the first pipe body 1 and the second pipe body 2 can be disassembled according to needs, realizing the disassembly and folding of the weeding machine, reducing its length when not in use, and providing convenience for the staff to carry and transport the weeding machine.

[0031] As Figure 1 , Figure 3 , Figure 4 shown in the figure, in order to realize the fixed connection and folding storage of the first pipe body 1 and the second pipe body 2, a holding handle 3 is arranged at the bottom of the second pipe body 2. A first sleeve 31 is arranged below the holding handle 3. The first sleeve 31 is sleeved on the second pipe body 2, and a fixed arc plate 33 is fixedly arranged below. A clamping arc plate 34 is arranged below the fixed arc plate 33 and is connected by bolts. A first connecting plate 11 is arranged at the top of the first pipe body 1, and a fastening bolt 12 penetrates through the ear plate of the first connecting plate 11. When the weeding machine needs to be used, the top of the first pipe body 1 is connected to the bottom of the second pipe body 2. Specifically, the end of the fastening bolt 12 is threadedly inserted into the threaded hole 32 of the first sleeve 31. In this way, the first pipe body 1 and the second pipe body 2 are firmly connected. Since a polygonal groove and a polygonal column are respectively arranged on the end faces of the first transmission rod 13 and the second transmission rod 22 that are close to each other, during the connection process of the first pipe body 1 and the second pipe body 2, the polygonal column is inserted into the polygonal groove, thereby stably connecting the first transmission rod 13 and the second transmission rod 22 and realizing the transmission of power.

[0032] When the weeding machine is not in use, the first pipe body 1 can be arranged parallel to the lower part of the second pipe body 2. In addition, the first pipe body 1 penetrates through the space formed by the fixed arc plate 33 and the clamping arc plate 34. At the same time, the bolt is rotated to make the clamping arc plate 34 approach the fixed arc plate 33. With the cooperation of the fixed arc plate 33 and the clamping arc plate 34, the first pipe body 1 is stably placed under the second pipe body 2, thereby reducing the length of the weeding machine when it is not in use. Of course, this device can also be used for removing herbaceous plants in other areas.

[0033] Embodiment 2

[0034] As Figure 1 、 Figure 5 shown, on the basis of Embodiment 1, in order to avoid the pain caused by the rod body of the weeding machine squeezing the waist of the staff, a supporting member 5 is arranged on the second pipe body 2 in this embodiment. The supporting member 5 is located inside the shoulder strap 4. The supporting member 5 is arranged in a U-shaped structure and has a large area to reduce the pressure of the weeding machine on the staff. Second sleeves 51 are arranged at both ends of the supporting member 5. The second sleeves 51 are sleeved on the second pipe body 2 through bearings. Therefore, the position of the supporting member 5 relative to the second pipe body 2 can be adjusted according to needs. Rubber columns 52 are arranged on the second sleeves 51, and slots 53 are arranged on the rubber columns 52. The end of the supporting member 5 is inserted into the slot 53. The rubber columns 52 function to eliminate the vibration generated when the weeding machine works.

[0035] Embodiment 3

[0036] As Figure 6 、 Figure 7 、 Figure 8As shown, on the basis of Embodiment 1 or Embodiment 2, in order to avoid damage to the circular blade of the weeding mechanism 7 caused by touching stones and bricks, in this embodiment, the weeding mechanism 7 is appropriately improved. Specifically, the weeding mechanism 7 includes a protective plate 71, a transmission mechanism 73, and a weeding device 72. The protective plate 71 and the transmission mechanism 73 are the same as the protective cover and the transmission system provided by the patent with the publication number CN103404296A. Here, a brief introduction to the transmission mechanism 73 is made. That is, in order to achieve transmission, at least a first bevel gear 731 and a second bevel gear 732 that mesh with each other are provided in the transmission mechanism 73. The second bevel gear 732 is connected to the first transmission rod 13, and the first bevel gear 731 is connected to the weeding device 72. Of course, devices for reducing friction between different components can also be provided in the transmission mechanism 73. It can refer to the transmission system or be determined according to actual needs during manufacturing. The weeding device 72 is set as a rope body (such as a cable). When the rope body rotates at a high speed, it can easily cut off herbaceous plants. Since the weeding device 72 is easily worn when contacting herbaceous plants, in order to be able to quickly disassemble and replace it, spheres are provided at adjacent ends of multiple weeding devices 72. At the same time, an upper ring plate 74 and a lower ring plate 75 connected by bolts are provided. Arc-shaped grooves 76 are provided at the edges of the mutually adjacent sides of the upper ring plate 74 and the lower ring plate 75. The spheres are located in the space formed by the arc-shaped grooves 76. Under the action of the spheres and the arc-shaped grooves 76, the weeding device 72 can be stably set on the side of the ring plate. When it is necessary to replace the weeding device 72, separating the upper ring plate 74 and the lower ring plate 75 can release the restriction on the weeding device 72.

[0037] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
