Description

Technical Field

[0001] The invention relates to the field of grass trimmers, and in particular to a grass trimmer head of a multi-color grass trimmer. Background Art

[0002] A lawn mower is a very popular garden tool. It has the ability to handle various uneven lawns at high speed. In particular, a rope-type lawn mower has a strong handling ability. It can encounter any hard obstacles without causing harm to the lawn mower itself. Even if it encounters damaging objects, it will only damage the rope and will not damage the lawn mower itself. For example, a lawn mower with patent CN201520001607.1 includes an extension rod, a casing, a lawn mower head, a handle, a main motor, and a main switch. The lawn mower head includes a receiving seat, a cover, and a wire reel. The wire reel has a first state of relative stillness with the receiving seat. The lawn mower also includes a wire-releasing mechanism. The lawn mower also includes a wire-releasing mechanism. The wire-releasing mechanism includes a wire-releasing electronic switch independent of the main switch and a control device. The wire-releasing electronic switch can be operated to electrically control the control device so that the wire reel is in a second state that can produce a rotational speed difference with the receiving seat. The operator does not need to interrupt the operation of the mower during work, and can release the line immediately as needed. The line release operation is simple and convenient. However, the mowing rope of this mower needs to be wound around its reel, which is very troublesome to wind around, and the tightness must be controlled. Once it is wound too tightly, it will cause the mowing rope to be unable to be dragged out when it needs to be extended, and the cover reel can only be disassembled to loosen it. In addition, there is no prompt structure to remind the user that the mowing rope needs to be replaced. When people do gardening work in parks outside, it is unlikely that they will carry extra mowing ropes at any time, and there is no way to predict how much rope is left. In addition, in the prior art, we often buy mowing ropes in bundles that are completely wound and very neat. However, when the machine is used to mow the grass, the line is pulled out and then wound onto the reel. The winding is very messy and there are more cases of winding errors in the double-slot winding grass trimmer head. Under the existing technology, everyone buys the mowing rope in a whole bundle, and then stretches it into a long rope and winds it back onto the reel. This operation takes a long time and the binding tightness must be suitable, otherwise there will be problems such as dead winding, loose buckles, and broken ropes. The rope bundle group is another type. At the beginning, the amount of rope and thickness required for the entire reel have been calculated, and they are neatly stacked layer by layer through industrialization, and glued as a whole with rice glue or other weak-viscosity glue. It is neat and standard, and there is no problem of winding ropes above. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-color mowing head, which can be used to install a mowing rope in a roundabout way, and can also be placed in a mowing rope bundle as a whole.

The disc column is provided with upper and lower threads on the spacer to match the thickness of the grass rope bundle, and the top buckle and the bottom buckle are screwed to the disc column from the top and bottom through the upper and lower threads.

[0036] As a preferred embodiment, a buffer spring-pressing sheet (4-41) is also provided at the top of the disk column, a spring-pressing sheet sleeve hole (4-42) is provided in the center of the buffer spring-pressing sheet, a pressure strip shaft block (4-43) is provided with the spring-pressing sheet sleeve hole protruding upward and downward, and a cross-shaped staggered convex rib (4-44) is provided at the bottom of the buffer spring-pressing sheet, and a limiting concave strip groove (4-45) is provided on the top buckle of the corresponding buffer spring-pressing sheet to match the staggered convex rib, and the limiting concave strip groove is also centrally staggered, and the shape matches the staggered convex rib, and the two can be mutually engaged, and the staggered convex rib is buckled into the limiting concave strip groove.

[0037] Preferably, the mowing rope set comprises at least a green rope body (4-36), a yellow rope body (4-37), and a red rope body (4-38), which are integrally injection-molded and arranged in a manner such that green is the head end, yellow is the middle end, and red is the tail end.

[0038] Preferably, the green, yellow and red ropes of the mowing rope group are arranged as follows: the last layer is red, at least the last two layers are yellow, and the other layers are green; or the green, yellow and red ropes of the bypass rope are arranged as follows: the last 1 meter is red, the last 2 to 3 meters are yellow, and the rest are green.

[0039] As a preferred top view, the green rope body, yellow rope body, and red rope body of the mowing rope group are arranged as follows: the green rope body is at an angle of 12 to 6 o'clock, the yellow rope body is at an angle of 6 to 9 o'clock, and the red rope body is at an angle of 10 to 12 o'clock. As a preferred top buckle and bottom buckle are both annular bodies, and a disk body thread (4-39) is arranged in the annular body. The top buckle and bottom buckle disk columns matching the thickness of the mowing rope bundle are provided with upper and lower threads on the spacer, and the top buckle and bottom buckle are screwed to the disk column from top to bottom.

[0040] Preferably, the top buckle and the bottom buckle are both annular bodies, a disc body thread (4-39) is arranged in the ring body, and upper and lower threads are arranged on the spacer on the disc column of the top buckle and the bottom buckle matching the thickness of the grass rope bundle, and the top buckle and the bottom buckle are screwed on the disc column from top to bottom.

[0041] Preferably, the bottom of the wire drum is covered or integrally provided with an anti-collision smooth cover (4-46).

[0042] Preferably, the surface of the mowing rope assembly is coated with a fluorescent layer or fluorescent powder.

[0043] Implementation method: Example 1: As Figure 2 As shown, the whole bundle of mowing rope is first made into a mowing rope group with green rope, yellow rope and red rope arranged in such a way that the last layer is red rope, at least the last two layers are yellow rope, and the other layers are green rope, or the green rope, yellow rope and red rope of the detour rope are arranged in such a way that the last 1 meter is red rope, the 2 to 3 meters at the end are yellow rope, and the rest are green rope. The overall arrangement of the green rope, yellow rope and red rope of the mowing rope group from top view is green rope from 12 o'clock to 6 o'clock, yellow rope from 6 to 9 o'clock and red rope from 10 to 12 o'clock; and the surface of the mowing rope group is coated with a fluorescent layer or fluorescent powder. Wind it directly in the upper and lower bundling grooves of the wire drum, insert the wire drum into the storage seat, pull out the mowing rope, pass it through the middle of the rope end card to the outside of the storage seat, and after the installation and arrangement is completed, cover the lower connecting cover from the bottom to the top, and set the bottom fixing hole (4-24) of the wire drum at the axis of the lower connecting cover. Finally, use the parallel piece on the top of the lower connecting cover to snap into the buckle and parallel groove to assemble the whole product; then use the top mounting hole screws to screw this product to the mower head or directly connect it to the drive rotating shaft;

[0044] Embodiment 2: When the mowing disc is combined, the line disc is combined with two parts, such as Figure 6As shown, the top buckle and the bottom buckle are both annular bodies, and a disc body thread (4-39) is arranged in the ring body. The top buckle and the bottom buckle disc column matching the thickness of the grass cutting rope bundle are provided with upper and lower threads on the spacer. The top buckle and the bottom buckle are screwed on the disc column from top to bottom, and the rope body is bundled. Its color combination is also: the arrangement of the green rope body, the yellow rope body, and the red rope body of the grass cutting rope group is that the last layer is the red rope body, at least the second layer from the bottom is the yellow rope body, and the other layers are the green rope body, or the arrangement of the green rope body, the yellow rope body, and the red rope body of the detour rope is that the last 1 meter is the red rope body, the tail 2 meters to 3 meters is the yellow rope body, and the rest are all green rope bodies; the overall arrangement of the green rope body, the yellow rope body, and the red rope body of the grass cutting rope group when viewed from above is that the angle from 12 o'clock to 6 o'clock is the green rope body, the angle from 6 to 9 o'clock is the yellow rope body, and the angle from 10 to 12 o'clock is the red rope body. Preferably, the top buckle and the bottom buckle are both annular bodies, and a disc body thread (4-39) is arranged in the ring body. The top buckle and the bottom buckle disc column of the annular body are matched with the thickness of the grass cutting rope bundle and are provided with upper and lower threads on the spacer. The top buckle and the bottom buckle are screwed on the disc column from top to bottom. The upper rope bundle and the lower rope bundle are directly put into the wire drum as a whole, and the wires are directly led to the outside. This method is direct and simple, and the operation is very convenient.

[0045] The operating methods of Examples 1 and 2 are the same. Green, red, and yellow, three colors or multiple colors represent different usage situations. For example, in Method 1, we now set the three-color line to set the line bundle from top to bottom, with the most green, yellow at the tail end occupying 2-3 meters, and red occupying about 1 meter. With this setting, it will prompt that yellow is used, reminding that there is not much line left, and it is best to bring a new line bundle when using it, while red prompts not to continue using it. In Method 2, the color of the line is constantly cycled, because the use of the line starts from the very end, and the optimal length range of the line (when it is neither long nor short, it is the time when the use efficiency is the highest). The optimal length determines the work efficiency, so once the green is used up, we have to pull out new lines alternately. After the green of the new line is completely pulled out, the red and yellow are used up, then we have to continue to pull out the line. In this way, we can maintain the best use efficiency for a long time during use.

[0046] Implementation method 3, such as Figure 5As shown, a buffer spring pressure sheet (4-41) is provided with a spring pressure sheet sleeve hole (4-42) in the center of the buffer spring pressure sheet, and a pressure strip shaft block (4-43) is provided with a projection upward and downward of the spring pressure sheet sleeve hole, and a staggered rib (4-43) in the shape of a rice character or a cross is provided at the bottom of the buffer spring pressure sheet, and a limited concave groove (4-44) is provided on the top buckle of the corresponding buffer spring pressure sheet to match the staggered rib. The limited concave groove is also staggered in the center, and the shape matches the staggered rib. The two can be engaged with each other, and the staggered rib is buckled into the limited concave groove. There is a safety standard in the prior art that the grass cutting rope head must be disassembled to replace the grass cutting rope, but in actual operation, only the lower connecting rod is replaced. In the case where the operation is carried out by tightening the cover, once the lawn mower is started, it will whip people or run idle out of control. Therefore, this implementation structure is designed, in addition to the screw-type control at the bottom, that is, the case of Example 1, and the staggered convex ribs in the limiting concave groove are controlled along with the buckle of the buffer spring plate and the wire-releasing spring. That is to say, in the tight situation, the wire drum is completely fit and buckled by the buffer spring plate, and the buckle of the wire-releasing spring is also very tight. However, once we loosen the screws at the bottom and the connection with the shaft of the lawn mower motor at the top, the buckle of the two is loosened, and the staggered convex ribs in the limiting concave groove are separated from the limiting concave groove.

[0047] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
