Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the mower of the present invention will be further described in detail by the following examples with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, the present invention provides a mower 100, the mower 100 being adapted for trimming a cut object on a lawn 200. The mower 100 is capable of cutting objects to be cut on the lawn 200. In the present invention, the grass is mainly trimmed, and only the grass is taken as an example for the trimming object. The mower 100 of the present invention can prevent the bottom of the mower body 110 from contacting the lawn 200 during steering, thereby preventing the lawn 200 from being worn out.
In the present invention, mower 100 includes a mower body 110. Mower body 110 is the main part of mower 100 that effects trimming of lawn 200. When the grass cutter 100 cuts the lawn 200, grass on the lawn 200 is cut by the grass cutter body 110. When the mower 100 needs to trim other areas of the lawn 200, the mower 100 needs to be turned, but the bottom of the mower body 110 may rub against the lawn 200 due to the turning of the mower 100, and the lawn 200 is easily worn out by the bottom of the mower body 110. Accordingly, the mower 100 of the present invention further comprises a support structure 120, the support structure 120 being mounted in the mower body 110. A distance exists between the bottom of the mower body 110 and the lawn 200 through the support structure 120. In this way, when the mower 100 is turned, the bottom of the mower body 110 cannot contact the lawn 200 due to the distance, so that the lawn 200 is prevented from being worn out by the bottom of the mower body 110.
Meanwhile, the support structure 120 can extend or retract the mower body 110 with respect to the mower body 110. That is, the support structure 120 may be telescopically movable. The support structure 120 is only activated when the mower 100 needs to be turned, and the support structure 120 extends out of the mower body 110. The support structure 120 is in the mower body 110 when the mower 100 does not need to be turned or after turning is completed. Thus, the interference of the supporting structure 120 on the trimming operation of the mower body 110 can be avoided, the supporting structure 120 is prevented from contacting with the lawn 200 when the mower 100 trims the lawn 200, the operation stability of the mower body 110 is ensured, the trimming effect of the mower 100 is ensured, and the mower is convenient to use.
The support structure 120 is extendable from the bottom of the mower body 110 relative to the mower body 110 to support the mower body 110 or portions of the mower body 110 away from the lawn 200. It should be noted that, after the support structure 120 extends from the bottom of the mower body 110, the support structure 120 can support the mower body 110 away from the lawn 200, so that the mower 100 can be turned to avoid the bottom of the mower body 110 contacting the lawn 200. In addition, the support structure 120 may perform operations other than steering after the mower body 110 is supported away from the lawn 200, so as to avoid the bottom of the mower body 110 contacting the lawn 200.
In the present invention, after the mower body 110 rotates around the supporting structure 120, the supporting structure 120 is retracted into the mower body 110. In this embodiment, before the mower body 110 needs to be turned, the supporting structure 120 extends from the bottom of the mower body 110, and at this time, a space exists between the bottom of the mower body 110 and the lawn 200, so that the mower body 110 will not contact with the lawn 200 when turning, and damage to the lawn 200 is avoided. When the mower body 110 is rotated to a desired position, the supporting structure 120 is retracted to the mower body 110, and at this time, the mower body 110 can continue to cut the lawn 200.
When the mower 100 performs a trimming operation, the bottom of the mower body 110 contacts the lawn 200 to trim the lawn 200. When steering is desired, the support structure 120 extends out of the mower body 110, supporting the mower body 110 such that the mower body 110 is away from the lawn 200. At this time, one end of the support structure 120 supports the mower body 110, and the other end of the support structure 120 contacts the lawn 200. When the mower body 110 is turned, the mower body 110 is only contacted with the lawn 200 through the supporting structure 120, so that the contact area between the mower 100 and the lawn 200 can be obviously reduced, and the bottom of the mower body 110 is prevented from being contacted with the lawn 200, so that the lawn 200 is prevented from being damaged due to friction between the bottom of the mower body 110 and the lawn 200 during turning.
The mower body 110 is rotatable about the support structure 120 to steer the mower body 110. It should be noted that the rotation of the mower 100 is performed around the supporting structure 120, so that the mower body 110 rotates, and the mower body 110 is turned in place. In this way, friction is not generated between the supporting structure 120 and the lawn 200, so that the lawn 200 is prevented from being damaged, and meanwhile, friction force between the supporting structure 120 and the lawn 200 can be reduced, so that the mower body 110 can be turned conveniently. Of course, the mower body 110 may also drive the supporting structure 120 to rotate together, and since the contact area between the supporting structure 120 and the lawn 200 is significantly smaller than the contact area between the bottom of the mower body 110 and the lawn 200, only the portion of the lawn 200 contacting the supporting structure 120 is damaged when the mower body 110 is turned. In order to reduce damage to the lawn 200 during steering, the mower 100 of the present invention rotates around the supporting structure 120 during steering, and does not drive the supporting structure 120 to rotate together, so as to reduce damage to the lawn 200.
With current tracked mowers, when the grass is cut and turned in situ, the control device in the tracked mower controls the wheels to turn the tracked mower, and when the grass is turned in situ, the tracks of the tracked mower are always in contact with the lawn. Because the crawler belt type mower can rub with the lawn when turning in situ, the lawn is easy to wear out, and the use is affected.
Before the mower body 110 of the mower 100 is turned, the supporting structure 120 can extend out of the mower body 110 to support the mower body 110 away from the lawn 200, so that a certain space exists between the mower body 110 and the lawn 200, and the bottom of the mower body 110 is prevented from contacting the lawn 200 during turning; after steering is complete, the support structure 120 is retracted into the mower 100 body, and the mower 100 body resumes operation. The mower 100 of the invention is contacted with the lawn 200 after extending out of the supporting structure 120 to realize the steering of the mower body 110, so that a certain distance exists between the bottom of the mower body 110 and the lawn 200, and when the mower body 110 performs steering and other operations, the contact friction between the bottom of the mower body 110 and the lawn 200 can be avoided, and further the bottom of the mower body 110 is prevented from grinding the lawn 200. Meanwhile, after the mower 100 turns, the operation capability of the mower 100 is not affected after the supporting structure 120 retracts into the mower body 110, so that the mower 100 can be used for trimming the lawn 200, and the mower is convenient to use.
As an embodiment, the mower 100 further includes a control device, a steering structure and a driving structure, and the control device and the driving structure are both installed in the mower body 110. The intelligent trimming operation of the mower 100 is realized through the control device, the automation capacity of the mower 100 is improved, the labor intensity of operators is reduced, the trimming consistency of the lawn 200 is ensured, and the appearance of the trimmed lawn 200 is neat. In the present invention, the control device is a controller.
The control device is connected with the supporting structure 120 through a driving structure, and the control device can control the driving structure to drive the supporting structure 120 to extend or retract. That is, the extension and retraction of the support structure 120 is accomplished by the control device without manual manipulation by an operator. When the mower body 110 needs to be turned, the control device controls the driving structure to drive the supporting structure 120 to extend out of the bottom of the mower body 110, so that the supporting structure 120 supports the mower body 110, a certain distance is ensured between the bottom of the mower body 110 and the lawn 200, the bottom of the mower body 110 is prevented from contacting the lawn 200 during turning, and the lawn 200 is prevented from being damaged.
The control device is also connected with the steering structure, and the control device controls the steering structure to drive the mower body 110 to automatically rotate. The control device can control the steering structure to rotate the mower body 110 by a required angle so as to facilitate the mower body 110 to perform trimming operation. In addition, the steering structure can also ensure that the steering of the mower body 110 and the supporting structure 120 cannot interfere, and ensure that the mower body 110 steers stably. The steering structure includes bearings mounted on the support structure 120. The steering structure can prevent the support structure 120 from interfering with other parts of the steering structure when controlling the rotation of the mower body 110, so as to ensure the stable steering of the mower body.
Further, mower 100 further comprises a height sensor electrically connected to the control device. The control device can control the height sensor to detect the height of the object to be trimmed in the lawn 200 to control the extension length of the support structure 120. In the present invention, the control device can control the height sensor to detect the actual height of grass on the lawn 200, the height sensor transmits the actual height signal of grass to the control device, and the control device controls the driving structure to drive the supporting structure 120 to extend for a required length, so as to avoid the bottom of the mower body 110 contacting the lawn 200. Of course, in other embodiments of the present invention, the control device also controls the support structure 120 to extend a fixed length, such as 60mm to 80mm, for the support structure 120 to extend fixedly, so as to avoid the bottom of the mower body 110 contacting the lawn 200.
Still further, the extension length of the supporting structure 120 is greater than or equal to the height of the object to be trimmed. That is, the protruding length of the support structure 120 should be equal to or greater than the height of the grass on the lawn 200. After the supporting structure 120 extends out of the mower body 110, the mower body 110 can be supported, so that the distance between the mower body 110 and the lawn 200 is greater than or equal to the height of grass, and therefore, when the mower body 110 turns, the bottom of the mower body 110 cannot contact with the grass in the lawn 200, friction between the bottom of the mower body 110 and the lawn 200 is avoided, and damage to the lawn 200 is avoided.
Further, the support structure 120 is retracted into the mower body 110, and the end of the support structure 120 is flush with the bottom of the mower body 110. That is, after the support structure 120 is retracted into the mower body 110, the end of the support structure 120 is in the same plane as the bottom of the mower body 110. In this way, the support structure 120 does not affect the lawn 200 when the mower body 110 performs a trimming operation. Meanwhile, the supporting structure 120 does not need to retract into the mower body 110, so that the movement stroke of the supporting structure 120 is reduced, and the efficiency is improved.
As one embodiment, support structure 120 is located at the center of gravity of mower body 110. Since the support structure 120 supports the mower body 110, the support structure 120 carries the entire weight of the mower body 110. In order to avoid the falling phenomenon of the mower body 110 during steering, the mower 100 is ensured to rotate stably, the supporting structure 120 should be located at the center of gravity of the mower body 110, and the mower body 110 can be kept balanced after the mower body 110 is supported by the supporting structure 120.
As an alternative embodiment, support structure 120 includes a support rod 121, and the control device is capable of controlling the support rod 121 to extend or retract relative to mower body 110. In this embodiment, the mower body 110 is supported by the supporting bar 121, and the supporting bar 121 is controlled to extend or retract by the control device. Also, the sectional shape of the support rod 121 may be polygonal, circular, or elliptical.
Of course, the number of the support rods 121 may be at least two, and the cross-sectional dimensions of at least two support rods 121 may be sequentially changed; the axes of the at least two support rods 121 are overlapped and sleeved; the control device controls at least two support rods 121 to be sequentially extended or sequentially retracted. That is, the extension length of the support structure 120 is at least twice the length of the support bar 121, so that the length range of the support bar 121 can be increased, so that the mower body 110 of the present invention can be supported at an arbitrary height.
When the number of the support rods 121 is at least two, the cross-sectional dimension of the support rods 121 is gradually increased, the support rod 121 having the largest cross-sectional dimension is located at the outermost side, and the support rod 121 having the smallest cross-sectional dimension is located at the innermost side. The support rods 121 are arranged from the outside to the inside according to the sectional size of the support rods 121 from the large to the small.
Further, the support structure 120 further includes a support chassis 122, and the support chassis 122 is disposed at an end of the support rod 121 away from the mower body 110. The support bar 121 contacts the lawn 200 through the support chassis 122. Since the support structure 120 supports the mower body 110, the support structure 120 carries the entire weight of the mower body 110. If the mower body 110 is supported only by the supporting bar 121, an end of the supporting bar 121 away from the mower body 110 may sink into the lawn 200, and the lawn 200 may be easily damaged. The supporting chassis 122 can increase the contact area between the supporting rod 121 and the lawn 200, so that the weight concentration of the mower body 110 is avoided, the supporting effect of the supporting structure 120 is ensured, the supporting structure 120 is prevented from sinking into the lawn 200, and the lawn 200 is prevented from being damaged.
Still further, the cross-sectional area of the support chassis 122 is 1.2 to 5 times the cross-sectional area of the support bar 121. The support chassis 122 increases the contact area between the support structure 120 and the lawn 200, so that the support structure 120 supports the mower body 110. If the cross-sectional area of the support chassis 122 is too small, the support effect of the support chassis 122 is not much different from that of the support rod 121. If the cross-sectional area of the support chassis 122 is too large, the trimming operation of the mower body 110 may be affected, and at the same time, the size of the mower body 110 may be increased. The height of the support chassis 122 is 0.15 to 0.6 times the cross-sectional area of the support bar 121 to facilitate extension and retraction of the support structure 120.
In addition, in the present invention, the supporting chassis 122 may also have a hollow structure, that is, there is a hollow at the contact position between the supporting chassis 122 and the lawn 200. That is, the area of the support chassis 122 in contact with the lawn 200 is smaller than the area of the support chassis 122. In this way, the contact area between the support chassis 122 and the lawn 200 can be reduced, damage to the lawn 200 is avoided, and the influence on the lawn 200 is reduced.
As one embodiment, the support structure 120 is a cylinder that includes a cylinder block and a telescoping rod that extends or retracts relative to the cylinder block. The cylinder block is installed in the mower body 110, and the telescopic rod can be extended or retracted with respect to the mower body 110. The mower body 110 can be supported by the air cylinder, so that the steering operation of the mower body 110 is facilitated, the mower body 110 is prevented from being contacted with the lawn 200, and the lawn 200 is prevented from being worn out.
The driving structure can be a gear transmission structure or a pump. When the support structure 120 is the support rod 121, the support structure 120 may be driven to extend and retract by a gear transmission structure or the like. When the support structure 120 is a cylinder, the telescoping rods may be driven to extend and retract by a pump. Of course, the driving structure may be other structures capable of driving the supporting structure 120 to achieve extension and retraction.
As one possible embodiment, mower 100 is a tracked mower. The crawler-type mower contacts the lawn 200 through the crawler, and the automatic walking and trimming operation of the crawler-type mower are realized. However, the crawler belt increases the contact area between the crawler mower and the lawn 200, and when the crawler mower turns, the crawler belt contacts with the lawn 200 to generate friction, so that the lawn 200 is easily worn out. Thus, the tracked mower is supported by the support structure 120 such that there is a distance between the crawler and the lawn 200, so that the crawler does not contact the lawn 200 when the tracked mower is turned, and the lawn 200 is prevented from being worn out.
Of course, the mower 100 of the present invention may be other types of mowers 100 besides crawler-type mowers, so as to avoid the mower 100 contacting the lawn 200 during steering, and further avoid damaging the lawn 200, which is convenient for use. In the present invention, mower 100 is preferably an intelligent tracked mower.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
