Description

Technical Field

[0001] The utility model relates to the technical field of plant pruning, in particular to an aquatic plant pruning device. Background Art

[0002] When the aquatic plants planted in the water are cut off from dead branches and rotten leaves or the plants are trimmed and arranged, it is necessary to wear water equipment and carry scissors used for pruning, which is very inconvenient for maintenance staff. For this reason, a novel aquatic plant pruning tool is disclosed in CN201821948598.7, which allows maintenance staff to prune aquatic plants without going into the water by extending the rod. The specific method is to set one or more main rods, and a connecting rod assembly is provided between the main rods, so that the two main rods are conveniently connected together, the overall length of the main rods is increased, and the plant pruning work in aquatic environments with different lengths is adapted. However, when the overall length of the main rod is too long, the cutter head is not easy to extend to the appropriate position of the aquatic plant during the pruning process, which easily causes the position of the pruning to deviate, resulting in a decrease in the ornamental value of the aquatic plants after pruning. At the same time, when the pruning tool is used for pruning, the cut branches and leaves will fall into the water, so that the staff needs to use the tool to salvage the aquatic plants again, thereby indirectly increasing the workload of the operator. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an aquatic plant pruning device, thereby solving the problems in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for trimming aquatic plants comprises a main rod, one end of which is provided with a cutter head, and the lower side of which is provided with a first floating block.

[0006] Furthermore, a bracket is slidably connected to the main rod, and a second floating block is provided on the lower side of the bracket.

[0007] Furthermore, one end of the main rod is fixedly connected to at least one holding rod.

[0008] Furthermore, the main rod is a hollow rod.

[0009] Furthermore, the cutter head portion includes an assembly plate, on the upper side of which are provided two parallel linear guide rails, one of which is slidably connected to two first sliders, each of which has a cutter installed on one side, and the other linear guide rail is slidably connected to two second sliders, each of which has a splint fixedly connected on one side.

[0010] The beneficial effects of the utility model are as follows: an aquatic plant trimming device provided by the utility model generates an upward buoyancy on the cutter head through the first floating block, which can reduce the staff's grip force on the trimming device of this embodiment, and form a fulcrum at the front end, so that the staff can easily determine the position of the cutter head after holding the main rod, avoiding the front end shaking and causing deviation in the trimming position. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a basic structural schematic diagram of the utility model;

[0012] Figure 2 It is a schematic diagram of the structure of the knife head. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example 1

[0014] like Figure 1-2 As shown, the utility model provides an aquatic plant pruning device, including a main rod 3, a cutter head 4 is provided at one end of the main rod 3, and a first floating block 6 is provided at the lower side of the cutter head 4. During use, the first floating block 6 generates an upward buoyancy on the cutter head 4, which can reduce the gripping force of the pruning device of this embodiment by the staff, and form a fulcrum at the front end, so that the staff can easily determine the position of the cutter head 4 after holding the main rod 3, and avoid the front end shaking and causing deviation of the pruning position. Example 2

[0015] On the basis of Example 1, the main rod 3 is slidably connected to the bracket 2, and the second floating block 1 is fixed to the lower side of the bracket 2. The bracket 2 includes a sliding sleeve and a heightening frame fixed together, the sliding sleeve can slide back and forth along the main rod 3, and the heightening frame is fixed to the second floating block 1. In this way, the position of the bracket 2 on the main rod 3 can be adjusted, and according to actual needs, the second floating block 1 is used to provide another supporting force for the main rod at the middle position of the main rod 3, so that the staff can further reduce the grip force of the trimming device of this embodiment, and can easily determine the position of the cutter head 4.

[0016] On this basis, in order to reduce the overall weight of the trimming device of this embodiment, the main rod 3 is set as a hollow rod.

[0017] At the same time, in order to facilitate the staff to hold the main rod 3, at least one holding rod 5 is fixedly connected to one end of the main rod 3. In this embodiment, two holding rods 5 are arranged symmetrically with the main rod 3 as the center, which makes it convenient for the staff to hold the main rod 3 with both hands. Example 3

[0018] In order to prevent the cut branches and leaves from falling into the water, the blade head 4 includes an assembly plate 41, and two parallel linear guide rails are arranged on the upper side of the assembly plate 41, one of which is slidably connected to two first sliders 44, and a cutter 45 is installed on one side of each first slider 44, and the blades of the two cutters 45 are arranged opposite to each other, and the other linear guide rail is slidably connected to two second sliders 42, and one side of each second slider 42 is fixedly connected to a clamping plate 43. During use, the two second sliders 42 are first moved relative to each other, so that the two clamping plates 43 clamp the branches and leaves to be cut, and then the two first sliders are moved relative to each other, and the clamped branches and leaves are cut off by the two cutters 45, and the cut branches and leaves are still clamped by the clamping plates, so that the branches and leaves will not fall into the water. In order to facilitate driving the two second sliders 42 to move toward or away from each other, two vertical plates 46 are fixedly connected on the upper side of the assembly plate 41, and a rotating shaft 48 is rotatably connected between the two vertical plates 46. A motor 49 is installed on one side of the vertical plate 46. The motor 49 is used to drive the rotating shaft 48 to rotate. The rotating shaft 48 is provided with a left-handed threaded section and a right-handed threaded section. One of the second sliders 42 is provided with a left-handed threaded hole, and the left-handed threaded section is threadedly connected in the left-handed threaded hole. The other second slider 42 is provided with a right-handed threaded hole, and the right-handed threaded section is threadedly connected in the right-handed threaded hole. Therefore, when the motor drives the rotating shaft to rotate forward or reverse, the two second sliders 42 move toward or away from each other. The method of controlling the two first sliders to move toward or away from each other is the same as the method of controlling the two second sliders 42 to move toward or away from each other, so it will not be repeated here. The method of controlling the motor adopts remote control, which is also a prior art and will not be repeated here.

[0019] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
