Description

Technical Field

[0001] This utility model relates to the technical field of lawnmowers, and in particular to a nut cover with a bearing mechanism. Background Technology

[0002] A lawnmower is a type of garden machinery used for trimming lawns and vegetation. It is widely used in home courtyards, parks, golf courses, and roadside green belts.

[0003] Currently, when installing lawnmower blades, a nut guard is used to secure the blades to the front of the lawnmower. The nut guard rotates with the blades to protect them and tighten the nut during use. However, the existing nut guard rotates at high speed with the gearbox during operation, frequently coming into contact with the ground and weeds. The friction generated by the high-speed rotation of the nut guard against these objects can easily cause damage and result in uneven lawn height, requiring secondary mowing and increasing the workload for operators.

[0016] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The following description, in conjunction with the accompanying drawings, describes a nut cover with a bearing mechanism according to an embodiment of the present invention.

[0018] This utility model provides a nut cover with a bearing mechanism, which can be used to fix the blades on a lawnmower. It can reduce the friction between the nut cover and the contacting object, extend the service life of the nut cover, and effectively avoid uneven lawn height when mowing, thereby reducing the labor intensity of workers.

[0019] like Figures 1-2As shown, a nut cover with a bearing mechanism according to an embodiment of the present invention may include a mowing assembly 1, a protective assembly 2, and a pressure plate assembly 3.

[0020] The protective component 2 is installed on the mowing component 1. The protective component 2 may include a protective shell 21, a bearing component 22, and a nut protective cover 23.

[0021] It should be noted that the bearing component 22 described in the above embodiments is a bearing, and the size of the bearing component 22 can be selected according to the size of the lawnmower.

[0022] It should be noted that the protective shell 21 described in the above embodiments has rounded corners on both sides, thereby reducing the resistance generated when the protective shell 21 is in contact with the ground.

[0023] The bearing component 22 is installed on the outside of the nut protective cover 23, and the nut protective cover 23 is connected to the mowing assembly 1. The protective shell 21 is installed on the side of the bearing component 22 away from the nut protective cover 23.

[0024] Specifically, the bearing component 22 reduces the friction between the nut protective cover 23 and the protective shell 21, thereby reducing the impact on the nut protective cover 23 during rotation and preventing the lawn mowing assembly 1 from contacting the ground under the action of the protective shell 21, thus ensuring the consistency of lawn mowing height.

[0025] The pressure plate assembly 3 is installed inside the protective assembly 2, and the pressure plate assembly 3 is located on both sides of the bearing component 22.

[0026] It should be noted that, under the action of the pressure plate assembly 3, the bearing component 22 is further fixed in the protective housing 21 to prevent the bearing component 22 from falling out of the protective housing 21 during rotation.

[0027] Specifically, during actual operation, when personnel are mowing the lawn, the mowing assembly 1 rotates at high speed to cut weeds. During the cutting process, the protective assembly 2 can contact the ground. At this time, the protective shell 21 of the mowing assembly 1 contacts the ground during the mowing process to ensure that the height of the lawn after mowing is consistent and to avoid uneven heights. Under the action of the bearing 22, the nut protective cover 23 will rotate with the rotation of the mowing assembly 1 to reduce the friction between the nut protective cover 23 and the protective shell 21, thereby reducing the damage to the nut protective cover 23, extending the service life of the nut protective cover 23, and effectively avoiding uneven lawn heights during mowing, thus reducing the labor intensity of the workers.

[0028] In one embodiment of this utility model, such as Figures 1-2 As shown, the mowing assembly 1 may include a gearbox 11 and a blade 12.

[0029] It should be noted that the gearbox 11 described in the above embodiments is prior art (therefore, it will not be described in detail).

[0030] The blade 12 is mounted on the gearbox 11 via a nut protective cover 23, and the gearbox 11 is connected to the blade 12 in a transmission manner.

[0031] Specifically, after the gearbox 11 is driven by a drive source such as a motor (not shown in the figure), the blade 12 is driven by the gearbox 11. Under the action of the protective component 2, the blade 12 is prevented from falling off during rotation. Then, the rotation of the blade 12 achieves the effect of mowing the lawn.

[0032] In one embodiment of this utility model, such as Figures 1-2 As shown, the pressure plate assembly 3 may include an upper pressure plate 31 and a lower pressure plate 32.

[0033] It should be noted that the lower pressure plate 32 described in the above embodiment has a slot for connecting the upper pressure plate 31, and the upper pressure plate 31 is set through the nut protective cover 23 and the bearing component 22.

[0034] The upper pressure plate 31 is installed on the outer side of the top of the nut protection cover 23, and the lower pressure plate 32 is installed on the outer side of the bottom of the nut protection cover 23.

[0035] Specifically, under the action of the upper pressure plate 31 and the lower pressure plate 32, the nut protection cover 23 is installed in the protective shell 21 to prevent the nut protection cover 23 from falling off the protective shell 21 during high-speed rotation.

[0036] In summary, the nut cover with bearing mechanism of this utility model can reduce the friction between the nut cover and the contacting object, extend the service life of the nut cover, and effectively avoid uneven lawn height when mowing the lawn, thereby reducing the labor intensity of the workers.
