Technical Field

The invention relates to the technical field of lawn mowers, and in particular to a lawn mower which is convenient for storage.

Background technique

A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It plays an important role in agricultural production and greatly improves agricultural production efficiency. However, due to the large size of the lawn mower and the long handle device, it takes up a lot of space when stored. Therefore, the storage of the lawn mower has always been a headache. Currently, the lawn mower is stored by adjusting the height of the handle device or by removing the handle device, but the operation is complicated. Especially for lawn mowers that need to be temporarily stored, the handle device needs to be repeatedly disassembled and assembled, making the storage operation extremely inconvenient.

Summary of the invention

An object of the present invention is to provide a lawn mower which is convenient for storage.

In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a lawn mower that is easy to store, including a body and a walking device, a lawn mowing device and a handle device arranged on the body, the handle device including a connecting rod and a handle, a connecting frame is provided at the end of the connecting rod away from the handle, a bracket is provided on the body, the connecting frame is rotatably connected to the bracket, and a limiting structure for limiting the rotation angle of the connecting frame is provided on the connecting frame, the limiting structure includes an arc block arranged on the connecting frame, a driving block arranged on the body and a limiting plate arranged on the driving block, a locking groove is provided on the arc block, and when the limiting plate and the locking groove are in a matched state, the handle device is located within the vertical projection range of the body.

Furthermore, the driving block is rotatably connected to the machine body, and the rotation of the driving block drives the limiting plate to rotate so that the cooperation between the limiting plate and the locking groove is separated.

Furthermore, the driving block is provided with a reset spring for resetting the driving block.

Furthermore, the locking groove is provided with a first guiding inclined surface, and the limiting piece is provided with a second guiding inclined surface matching with the first guiding inclined surface.

Furthermore, when the connecting rod is located at the initial position, the angle between the limiting piece and the locking groove is a, 90°＜a≤110°.

Furthermore, a positioning groove is provided on the arc block. When the connecting rod is located at the initial position, the angle between the limiting piece and the positioning groove is b, and 50°≤b≤65°.

Furthermore, the connecting frame includes a first connecting rod connected to the connecting rod and a second connecting rod connected to the bracket, the bracket includes a first bracket and a second bracket, the second connecting rod is provided with two and respectively cooperates with the first bracket and the second bracket, and the limiting structure is located on the first bracket and/or the second bracket.

Furthermore, the mowing device includes a blade and an outer rotor motor for driving the blade to rotate.

Furthermore, the walking device includes front wheels and rear wheels, two front wheels are provided and are respectively located on the left and right sides of the fuselage, the distance between the two front wheels away from each other is L1, the width of the handle is L2, and 1.2≤L1/L2≤1.5.

Furthermore, the connecting rod is a telescopic rod.

After adopting the above technical solution, the present invention has the following advantages:

1. By setting a locking groove on the arc block, when the limit plate and the locking groove are in a matched state, the handle device is located within the vertical projection range of the machine body, so that the handle device and the machine body are in a folded state. Without removing the handle device, the occupied space of the lawn mower is reduced to the greatest extent, making the storage of the lawn mower more convenient. At the same time, the position of the handle device is locked by the cooperation of the limit plate and the locking groove. During the storage process, the connecting rod will not rotate, making the storage of the lawn mower safer.

2. By setting a driving block to be rotatably connected to the machine body, rotating the driving block causes the driving block to drive the limit plate to rotate, thereby separating the limit plate from the locking groove, and releasing the locked state. The unlocking can be achieved by simply rotating the driving block, making the unlocking operation of the handle device relatively simple.

3. By setting a reset spring, the driving block can automatically return to its initial state when there is no force, so that when the locking groove on the arc block rotates to the top of the limit plate, it can automatically cooperate with the limit plate to lock the position of the handle device, making the locking operation of the handle device more convenient and facilitating the storage of the lawn mower.

4. By setting a first guiding bevel on the locking groove and a second guiding bevel on the limiting plate, the first guiding bevel cooperates with the second guiding bevel, so that the limiting plate can be easily separated from the locking groove when rotating, further facilitating the unlocking operation.

5. When the connecting rod is in the initial position, the angle between the limit plate and the locking groove is set within the range of 90° to 110°, so as to ensure that the connecting rod can be locked with the locking groove after rotating 90° to 110°. When a≤90°, the handle device cannot be located within the projection range of the machine body in the vertical direction, and the effect of reducing the storage space cannot be achieved; when a＞110°, due to the long length of the connecting rod, the position of the handle is easily not within the projection range of the machine body in the vertical direction, and the effect of reducing the storage space cannot be achieved.

6. By setting a positioning groove on the arc block, when the connecting rod is in the initial position, the angle between the limit piece and the positioning groove is in the range of 50° to 65°, so that the handle device can freely adjust the angle to adapt to users of different heights and different operating distances, making the operation of the lawn mower more comfortable. When b < 50°, the adjustable angle is small and cannot meet the needs of most people; when b > 65°, due to the large vertical force component, the ground resistance to the lawn mower is large when the lawn mower turns, which is more difficult to use and prone to accidents.

7. By providing the first bracket and the second bracket, the two second connecting rods are rotatably connected to the first bracket and the second bracket respectively, so that the use of the handle device is more stable and reliable. The limiting structure can be provided with one on the first bracket or on the second bracket, or two, and the limiting structure is provided on both the first bracket and the second bracket.

8. The mowing device includes a blade and an outer rotor motor for driving the blade to rotate. The outer rotor motor is small in size and high in working efficiency. It can save space for the mower while meeting the mowing power of the mower, reduce the size of the mower, and make the mower easier to store.

9. By setting the distance between the two front wheels on the sides away from each other to L1, the width of the handle to L2, and 1.2≤L1/L2≤1.5, the width of the handle is smaller than the width of the whole machine, which is convenient for the storage of the lawn mower. At the same time, the width of the handle is more appropriate and convenient for the operator to hold. When L1/L2＜1.2, the connecting rod is long and is easy to deviate during processing and use. It is ensured that when the lawn mower is folded and stored after long-term use, the handle can still be located within the projection range of the machine body in the vertical direction, making the lawn mower more convenient to store.

10. By setting the connecting rod as a telescopic rod, the storage space required for the lawn mower in the storage position is further reduced.
