Description

Technical Field

[0001] This application relates to the field of lawn mower technology, and in particular to a lawn mower head. Background Technology

[0002] A lawn mower is a common and practical gardening tool, especially suitable for trimming lawns in villas and gardens. Currently, most lawn mower heads on the market require disassembly during assembly, with the rope wound around a reel before the head is reassembled. During assembly, the mowing rope easily comes undone, which is time-consuming and labor-intensive.

[0003] Meanwhile, during the mowing process, the mowing head directly contacts the ground as it rotates, which can easily create holes, damaging the turf and ruining its appearance. Therefore, the purpose of this application is to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a grass trimming head to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a hay trimmer head, comprising: a hay trimmer head base with a first through-hole for rope passing through its outer periphery; a hay trimmer head cover disposed above the hay trimmer head base; a knob that can be rotated on the hay trimmer head cover, the top of the knob being provided with a rotating component that can rotate relative to the knob; a winding wheel rotatably disposed within the hay trimmer head base, the center of the outer periphery of the winding wheel having a second through-hole for rope passing through it, the knob being able to drive the winding wheel to rotate; and hay trimming rope passing through the first through-hole and the second through-hole and wound around the outer periphery of the winding wheel; by rotating the knob, the first through-hole and the second through-hole are aligned and the hay trimming rope passes through them, and rotating the knob again can drive the hay trimming rope to wind around the winding wheel.

[0007] In some embodiments, a partition plate is provided at the center of the outer periphery of the winding wheel, and the partition plate forms winding portions with openings on both sides of the second threading hole at both ends.

[0008] In some embodiments, the rotating assembly includes a rotating block and a bearing, wherein the inner ring of the bearing is fixedly connected to one side of the rotating block by screws, and the outer ring of the bearing is mounted on the knob by screws.

[0009] In some embodiments, a plurality of first inclined blocks arranged in a circumferential array are formed on one side of the winding wheel connected to the bearing, and a plurality of second inclined blocks arranged in a circumferential array are formed on the other side.

[0010] In some embodiments, the inner side of the tweezers cap is formed with circumferentially distributed ribs, which can restrict the rotation of the winding reel by means of a first inclined block.

[0011] In some embodiments, the hay-beating head seat is provided with a connecting part, and a spring is provided on the connecting part to abut against one side of the winding wheel and drive the winding wheel to move in the direction of the knob.

[0012] In some embodiments, the outer periphery of the connecting portion is formed with a plurality of vertical ribs, which can limit the rotation of the winding wheel by means of a second inclined block.

[0013] In some embodiments, a notch is provided on the bottom of the knob, and a limiting block that cooperates with the notch is provided on the winding wheel.

[0014] In some embodiments, the hay-cutting head seat is provided with a hay-cutting rope sheath on the first rope hole.

[0015] The beneficial effects of this application are: the knob can control the winding wheel to rotate so that the first rope hole and the second rope hole are on the same straight line, so that the straw rope can pass through the first rope hole and the second rope hole without disassembling the straw head, and the straw rope can be wound on the winding wheel by rotating the knob, so that the straw rope can be assembled without disassembling the straw head.

[0016] The rotating component can rotate independently relative to the turf head under the action of the bearing. When the rotating component is in contact with the ground, the rotating component can remain stationary while the turf head is rotating, preventing the turf head from creating holes in the ground it is in contact with and affecting the turf.

[0017] At the same time, the first and second inclined blocks on the winding reel can simultaneously restrict both ends of the winding reel, preventing the winding reel from moving radially, thus reducing the dynamic balance value of the grass trimming head and making the work easy and comfortable.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0027] In the embodiments of this application, please refer to Figure 1-6 As shown, this application provides a hay trimmer head, mainly comprising: a hay trimmer head base 1, with a through first rope hole 11 on its outer periphery; a hay trimmer head cover 2, disposed above the hay trimmer head base 1; a knob 3, which is rotated on the hay trimmer head cover 2, and a rotating component 31 is disposed on the top of the knob 3, the rotating component 31 being able to rotate relative to the knob 3; a winding wheel 4, rotatably disposed inside the hay trimmer head base 1, with a through second rope hole 41 at the center of the outer periphery of the winding wheel 4, the knob 3 being able to drive the winding wheel 4 to rotate; and hay trimming rope 5, which passes through the first rope hole 11 and the second rope hole 41 and is wound around the outer periphery of the winding wheel 4; by rotating the knob 3, the first rope hole 11 and the second rope hole 41 are aligned and the hay trimming rope 5 is passed through, and rotating the knob 3 again can drive the hay trimming rope 5 to wind around the winding wheel 4.

[0028] Specifically, when it is necessary to install the grass trimming rope 5, the winding wheel 4 is driven to rotate synchronously by rotating the knob 3, so that the second rope hole 41 can be aligned with the first rope hole 11 and placed on the same straight line. At this time, the grass trimming rope 5 can be passed through the first rope hole 11 and the second rope hole 41 at the same time, and the length of the grass trimming rope 5 at both ends of the grass trimming head is equal. Then, rotate the knob 3 to make the grass trimming rope 5 wrap around the outer circumference of the winding wheel 4, so as to realize the quick assembly of the grass trimming rope 5.

[0029] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0030] refer to Figure 3 As shown in Figure 4, a partition plate 42 is provided at the center of the outer periphery of the winding wheel 4. The partition plate 42 is located at both ends of the second thread hole, forming winding portions 421 with openings on both sides of the partition plate 42. With this arrangement, when the knob 3 drives the winding wheel 4 to rotate, the straw rope 5 at one end will enter one side of the partition plate 42 through the opening on the winding portion 421, so that the straw ropes 5 at both ends will not be tangled together, which is beneficial to the assembly of the straw rope 5.

[0031] refer to Figure 2 As shown in Figure 3, in order to enable the rotating assembly 31 to rotate relative to the hay trimmer head shell and the hay trimmer head seat 1, the rotating assembly 31 includes a rotating block 311 and a bearing 312. The inner ring of the bearing 312 is fixedly connected to one side of the rotating block 311 by a screw 313, and the outer ring of the bearing 312 is set on the knob 3 by a screw 313.

[0032] Specifically, on one side of the winding wheel 4 connected to the bearing 312, a plurality of first inclined blocks 43 are formed in a circumferential array, and on the other side, a plurality of second inclined blocks 44 are formed in a circumferential array. The first inclined blocks 43 and the second inclined blocks 44 can restrict the rotation of the winding wheel 4.

[0033] Reference Figure 5 As shown, the inner side of the grass-beating head cover 2 is formed with circumferentially distributed ribs 21. The ribs 21 can restrict the rotation of the winding wheel 4 by means of the first inclined block 43. Specifically, the higher end of the first inclined block 43 can abut against one side of the rib 21 to restrict the winding wheel 4 from rotating to this side. The lower end of the first inclined block 43 can lift the winding wheel 4 and slide over the rib 21 when the knob 3 is rotated.

[0034] Reference Figure 6 As shown, the grass trimmer head 1 is provided with a connecting part 12, and a spring 121 is provided on the connecting part 12 to abut against one side of the winding wheel 4 and drive the winding wheel 4 to move in the direction of the knob 3. This arrangement allows the winding wheel 4 to be quickly reset after being lifted.

[0035] The outer periphery of the connecting part 12 is formed with a plurality of vertical ribs 122. The vertical ribs 122 can restrict the rotation of the winding wheel 4 by means of the second inclined block 44. With this configuration, the higher end of the two ends of the second inclined block 44 can abut against one side of the vertical rib 122 to restrict the winding wheel 4 from rotating to this side. The lower end of the two ends of the first inclined block 43 can undergo slight elastic deformation or push open the winding wheel 4 to slide over the vertical rib 122 when the knob 3 is rotated.

[0036] For illustration, knob 3 can drive the winding wheel 4 to rotate in one direction or rotate in both directions by pressing knob 3.

[0037] Specifically, the oblique directions of the first oblique block 43 and the second oblique block 44 should be consistent, and the rotation direction of the hay-trimming head should be equal to the direction of the limiting of the first oblique block 43 and the second oblique block 44. The first oblique block 43 and the second oblique block 44 can limit the rotation of both sides of the winding wheel 4 so that the winding wheel 4 will not move radially due to unidirectional restriction, thereby improving the dynamic balance of the hay-trimming head, reducing the vibration value when it is working, and increasing the working comfort of the workers.

[0038] Specifically, in order for the knob 3 to drive the winding wheel 4 to rotate, a notch 32 is provided on the bottom of the knob 3, and a limiting block 45 that cooperates with the notch 32 is provided on the winding wheel 4.

[0039] Preferably, in order to protect the trimming rope 5, the trimming head seat 1 is provided with a trimming rope sheath 111 on the first rope hole 11.

[0040] Preferably, in order to facilitate alignment of the first rope hole 11 and the second rope hole 41 with the user, the grass trimmer cover 2 and the knob 3 are provided with markings 6 corresponding to the first rope hole 11 and the second rope hole 41.

[0041] The various embodiments of this application have been described in detail above. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
