Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an electric saw weeder for a photovoltaic station. Background Art

[0002] Since solar photovoltaic panels can block sunlight and reduce water evaporation, it is beneficial to the growth of plants at the bottom, especially creating a better growth environment for some shade-tolerant and drought-tolerant plants. Therefore, plants near photovoltaic panels will grow rapidly, and some plants will even be higher than the minimum height of photovoltaic panels, thus affecting the power generation efficiency of photovoltaic panels. Therefore, vegetation that grows too lush needs to be cleared. Currently, most cleaning methods are combined with agriculture and animal husbandry, and are handled by herbivores such as cattle and sheep.

[0003] However, for some remote solar power plants far away from towns, the problem cannot be solved fundamentally, so it is solved by weeders. Therefore, the equipment used for weeding is a chain weeder or a rotary tiller. The former harvests by quickly rotating the chain. There are dense solar panel mounting bases inside the power station. During the harvesting process, the chain is easily broken once it touches the base. Therefore, it is necessary to frequently replace the weeding chain or accurately control the weeding position. However, the weeding equipment cannot remove the roots of weeds, so the removal is not thorough enough. For example, tumbleweeds will grow again in a short time. Although the latter can remove the roots of weeds, the weeds are easy to entangle the shaft, causing the rotary tiller to get stuck. It is not suitable for handling high weeds. For this reason, we proposed a photovoltaic station electric saw weeder to solve the above problems. Utility Model Content

[0004] The present application provides a photovoltaic station electric saw weeder, which solves the problem that lush vegetation in solar power generation areas affects photovoltaic power generation efficiency and is difficult to clean.

[0005] The present application provides a photovoltaic station electric saw weeder, comprising a protective shell, a reducer installed in the protective shell, a handheld bracket fixed to one side of the protective shell, a mounting plate fixed to the handheld bracket, a small engine mounted on the mounting plate, an output shaft of the small engine passes through the mounting plate and the protective shell and is connected to the reducer, rotating rollers are installed at both ends of the reducer, a plurality of tilling knives are installed on the rotating rollers, two rotating shafts are installed between the protective shell and the mounting plate, sprockets are installed on the two rotating shafts and the output shaft, the sprockets are connected by chains, and saw blades are installed on the two rotating shafts.

[0006] Preferably, a first protective shell is installed on the protective shell, and the output shaft and the two rotating shafts are all located in the first protective shell.

[0007] Preferably, a second protective shell is also installed on the protective shell, the second protective shell is located inside the first protective shell, and the chain and the sprocket are both located inside the second protective shell.

[0008] Preferably, a support frame is fixed between the handheld bracket and the small engine.

[0009] Preferably, a hand-held part is also installed on the upper part of the hand-held bracket.

[0010] Preferably, a counterweight frame is provided on the first protective shell.

[0011] Preferably, the small engine is a gasoline engine.

[0012] It can be seen from the above technical scheme that the present application provides a photovoltaic station electric saw weeder. When the present application is in use, the staff holds a handheld bracket and starts a small engine. The output shaft of the small engine drives two rotating shafts to rotate through a sprocket and a chain, and drives two sets of saw blades to rotate through the two rotating shafts, thereby clearing the weeds on the path. It is worth noting that the harvesting range of the saw blade is limited to the front, that is, the side away from the handheld bracket. When passing by the solar base, the side of the protective shell passes through the base of the solar panel to prevent the saw blade from contacting the base of the solar panel. After the saw blade has processed the weeds, the output shaft drives the two rotating rollers to rotate through the reducer, driving the tiller to destroy the roots of the weeds and reduce the growth of weeds.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Through the setting of a small engine, a rotating shaft and a saw blade, the saw blade can be driven to quickly cut and clean the weeds. The rotation range of the saw blade does not exceed the two sides of the protective shell, so as to avoid obstacles in front of the saw blade and protect the saw blade;

[0015] 2. Through the setting of the reducer, rotating roller and tillage knife, the tillage knife can be driven to destroy the roots of weeds, which can effectively destroy the roots of weeds and reduce the growth of weeds.

[0016] In summary, the present application can effectively inhibit the regrowth of weeds by first harvesting the weeds and destroying the roots of the weeds during the harvesting process. The present application has a high harvesting efficiency through the structure of the saw blade, and the edge of the saw blade of the present application will not run beyond the side of the protective shell, so the saw blade can also be protected.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] See also Figure 1-4, a photovoltaic station electric saw weeder, the present application is used for weed removal work in solar power stations, and provides a device that can quickly harvest weeds and inhibit weed regrowth, specifically including a protective shell 1, the protective shell 1 is a cover with an opening on one side, the opening side faces downward when installed, a reducer 2 is installed in the protective shell 1, which is used to change the driving direction and transmission, a handheld bracket 10 is fixed to one side of the protective shell 1, the handheld bracket 10 is tilted, and when in use, the hand is tilted downward, which is convenient for the user to operate, and a handheld part 12 is also installed on the upper part of the handheld bracket 10. During operation, through the handheld part 12 The present application is operated by holding the present application, a mounting plate 4 is fixed on the handheld bracket 10, a small engine 3 is mounted on the mounting plate 4, the small engine 3 of the present application is a gasoline engine, with large torque and high power, which can meet the power requirements of the present application and is convenient for outdoor work, the output shaft 15 of the small engine 3 passes through the mounting plate 4 and the protective shell 1 and is connected to the reducer 2, the small engine 3 is decelerated at the reducer 2 and reversed, and rotating rollers 8 are installed at both ends of the reducer 2, the two rotating rollers 8 are driven to rotate by the reducer 2, and a plurality of soil turning knives 9 are installed on the rotating rollers 8, such as Figure 1 As shown, one side of the tilling knife 9 is fixed on the rotating roller 8, and the other side extends outward. During the rotation of the rotating roller 8, the tilling knife 9 can be driven to turn over the ground, destroy the roots of weeds, reduce the regrowth of weeds, and thus reduce the frequency of weed cleaning.

[0025] Two rotating shafts 14 are installed between the protective shell 1 and the mounting plate 4. Sprockets 16 are installed on the two rotating shafts 14 and the output shaft 15. The sprockets 16 are connected by a chain 13. When the output shaft 15 rotates, the two rotating shafts 14 can be driven to rotate quickly through the chain 13. Saw blades 7 are installed on the two rotating shafts 14. The present application uses the saw blade 7 to clean the weeds. Compared with the cleaning chain, the saw blade 7 has a better harvesting efficiency. It is worth noting that the saw blade 7 in the present application has a serrated cutting surface on one side.

[0026] In some embodiments of the present invention, since the weeds will tilt to the side of the present invention when they are cut and fallen, in order to reduce the weeds from being drawn into the saw blade 7 again and affecting the cutting power, a first protective shell 5 is installed on the protective shell 1, and the output shaft 15 and the two rotating shafts 14 are all located in the first protective shell 5, so that part of the cut saw blade 7 is exposed, which does not affect the cutting efficiency, and the fallen weeds fall on the first protective shell 5 to avoid being drawn into the saw blade 7 and the rotating shaft 14, thereby protecting the rotating shaft 14.

[0027] In some embodiments, a small amount of weeds will still enter the first protective shell 5 during cutting, affecting the normal operation of the sprocket 16 and the chain 13. Therefore, a second protective shell 6 is also installed on the protective shell 1. The second protective shell 6 is located in the first protective shell 5. The chain 13 and the sprocket 16 are both located in the second protective shell 6 to protect the sprocket 16 and the chain 13.

[0028] In the present application, in order to further stabilize the operation of the small engine 3 , a support frame 11 is fixed between the handheld bracket 10 and the small engine 3 to provide movably supported support for the small engine 3 .

[0029] In some embodiments, since some soils are hard, the soil-turning knife 9 may not penetrate deep enough into the soil, thereby affecting the destruction of the weed roots. Therefore, a counterweight frame 17 is provided on the first protective shell 5, and heavy objects can be placed on the counterweight frame 17 to increase the overall weight of the application and achieve the purpose of destroying the roots.

[0030] It can be seen from the above technical scheme that when the present application is in use, the staff holds the handheld bracket 10 and starts the small engine 3. The output shaft 15 of the small engine 3 drives the two rotating shafts 14 to rotate through the sprocket 16 and the chain 13, and drives the two sets of saw blades 7 to rotate through the two rotating shafts 14, so as to clear the weeds on the path. It is worth noting that the harvesting range of the saw blade 7 is limited to the front, that is, the side away from the handheld bracket 10. When passing by the solar base, the side of the protective shell 1 passes through the base of the solar panel to prevent the saw blade 7 from contacting the base of the solar panel. After the saw blade 7 has processed the weeds, the output shaft 15 drives the two rotating rollers 8 to rotate through the reducer 2, and drives the soil-turning knife 9 to destroy the roots of the weeds and reduce the growth of weeds.
