DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1 to 7 As shown, a riding lawn mower comprises a frame 1, a mowing device 4, a pedal platform 5 and a fixed plate 2; the frame 1 is arranged on the ground through a walking assembly 11, and an armrest assembly 6 and a backrest assembly 7 are also respectively arranged on the frame 1; the mowing device 4 is arranged on the frame 1; the pedal platform 5 is arranged on a side of the frame 1 away from the mowing device 4; the fixed plate 2 is arranged between the armrest assembly 6 and the backrest assembly 7, and a seat mechanism 3 whose size can be adjusted is arranged on the fixed plate 2.

[0025] When the lawn mower device is needed, the relevant personnel can first adjust the seat mechanism 3 on the fixed plate 2 to select a suitable size, and then sit on the seat mechanism 3, and then lean their waist on the backrest assembly 7, and then put their hands on the armrest assembly 6, and at the same time place both feet on the foot platform 5. At this time, the walking assembly 11 and the mowing device 4 are driven by the foot platform 5 to work simultaneously, so that the whole frame 1 is driven to move by the walking assembly 11, thereby driving the mowing device 4 to mow a large area. The seat mechanism 3 can adjust itself, so that when operators of different body shapes use the lawn mower device, the use experience will be better, and then the work efficiency when using the mowing device 4 for mowing can be improved, and the practicality of the whole lawn mower device can be improved simultaneously.

[0026] Reference Figure 2 As shown, the seat mechanism 3 includes a seat 31 and a movable plate 32; the seat 31 is horizontally arranged above the fixed plate 2; the movable plate 32 is movably arranged on the seat 31, and a limiting groove 33 for the movable plate 32 to move is arranged on the seat 31.

[0027] The movable plate 32 can move in the limit groove 33 of the seat 31. When the operator needs to make adjustments, he only needs to pull the movable plate 32 to move in the limit groove 33 of the seat 31, so as to adjust the overall length and find the best size that suits him best. When the operator sits on the seat 31, the physical feeling will be better, thereby improving the work efficiency when mowing with the lawn mower device.

[0028] Reference Figure 4As shown, the seat 31 is provided with an adjustment component 34 capable of automatically adjusting the movable plate 32, and the adjustment component 34 includes a rotating shaft 341, a gear 342 and a rack 343; the rotating shaft 341 is rotatably arranged on the seat 31; there are two gears 342 that are symmetrically arranged on the seat 31, and the two gears 342 are connected to the rotating shaft 341; the number of racks 343 is the same as the number of gears 342, and the top of the rack 343 is connected to the bottom of the movable plate 32, and the rack 343 is meshingly connected to the gear 342.

[0029] By directly driving the rotating shaft 341 to rotate, when the rotating shaft 341 rotates, it will synchronously drive the gear 342 to rotate, and then drive the rack 343 to move back and forth on the seat 31, so that the movable plate 32 can be directly driven to move in the seat 31, and then when it is necessary to adjust the position of the movable plate 32 on the seat 31, it is only necessary to directly rotate the rotating shaft 341 to adjust the movable plate 32. This makes the operation simpler and makes the movable plate 32 move more smoothly. In addition, through the engagement between the gear 342 and the rack 343, there will be a resistance, which can also prevent the movable plate 32 from automatically resetting.

[0030] Reference Figure 2 and Figure 5 As shown, a buffer assembly is provided on the fixed plate 2, and the buffer assembly includes a limiting shaft 211 and a first spring 212; at least one of the limiting shafts 211 is arranged at the bottom of the seat 31; the first spring 212 is sleeved on the limiting shaft 211, and one end of the first spring 212 is arranged to abut against the seat 31, and the other end is arranged to abut against the fixed plate 2.

[0031] When the mowing device 4 is mowing the grass, the ground may be uneven, which will cause the frame 1 to shake. When the frame 1 shakes, the operator's own weight is constant, so the shaking will apply pressure to the seat 31 again, so that the seat 31 will squeeze the first spring 212, causing the first spring 212 to deform and have an elastic restoring force, thereby driving the seat 31 to reset. In this way, when the frame 1 shakes, it will not affect the operator, and can further enhance the operator's physical sensation when sitting on the seat 31, and can also reduce the impact on the mowing device 4 when mowing the grass.

[0032] Reference Figure 5 and Figure 6As shown, a limiting assembly is provided on the fixed plate 2, and the limiting assembly includes a limiting block 2131, a fixed block 2132 and a sliding block 2133; at least one limiting block 2131 is provided on the fixed plate 2; the number of the fixed blocks 2132 is the same as the number of the limiting blocks 2131, and the fixed blocks 2132 are provided at the bottom of the seat 31, and the fixed blocks 2132 are slidably connected to the limiting blocks 2131; at least one sliding block 2133 is provided on the limiting block 2131, and the fixed block 2132 is provided with a sliding groove 2134 that cooperates with the sliding block 2133.

[0033] Because the fixed plate 2 and the seat 31 can move relative to each other, the fixed block 2132 can move on the limit block 2131, so that there is a vertical limiting effect between the fixed plate 2 and the seat 31, and the slider 2133 can only move in the slide groove 2134 of the fixed block 2132, so that the fixed block 2132 and the limit block 2131 can be limited in the horizontal direction, and the fixed plate 2 and the seat 31 are also limited in the horizontal direction, so that the seat 31 will not be separated from the fixed plate 2, and the buffering effect of the first spring 212 will not be affected.

[0034] Reference Figure 4 As shown, a manual turntable 3411 that can be used for holding is also provided on the rotating shaft 341 , and a handle 3412 is also provided on the manual turntable 3411 .

[0035] When the rotating shaft 341 is driven to rotate, manual operation is required. In this way, the rotating shaft 341 can be directly driven to rotate by holding the manual dial 3411 and directly rotating the manual dial 3411. This operation is more labor-saving and more convenient. By setting the handle 3412, the manual dial 3411 can be driven to rotate by holding the handle 3412 directly, which is more labor-saving and more convenient.

[0036] Reference Figure 3 and Figure 7 As shown, the backrest assembly 7 includes a fixed seat 72 and a backrest frame 74; the fixed seat 72 has two and is symmetrically arranged on the frame 1, the fixed seat 72 is provided with a rotating seat 73, the rotating seat 73 is provided with a connecting pipe 71, and the fixed seat 72 is provided with an abutting portion 75 that can abut against the rotating seat 73; the backrest frame 74 is movably arranged on the connecting pipe 71, and the connecting pipe 71 is provided with a positioning groove 711 for the backrest frame 74 to move.

[0037] The swivel base 73 is then set to the position where the connecting tube 71 is located, and the swivel base 73 is set to the position where the connecting tube 71 is located.

[0038] Reference Figure 7 As shown, the connecting tube 71 is provided with a fixing portion 76 that can be used to fix the backrest frame 74, and the fixing portion 76 includes an abutting shaft 761, a limit box 765, a gripping block 764 and a second spring 763; the abutting shaft 761 is provided on the connecting tube 71, and one end of the abutting shaft 761 close to the connecting tube 71 can be arranged to abut the connecting tube 71 and the backrest frame 74, and the backrest frame 74 is provided with a plurality of abutting holes 741 for the abutting shaft 761 to abut; the limit box 765 5 is sleeved on the abutment shaft 761, and the limit box 765 is connected to the connecting tube 71, and the holding block 764 is arranged on the side of the abutment shaft 761 close to the limit box 765; the limit ring 762 is coaxially arranged on the abutment shaft 761, and the limit ring 762 can be abutted with the connecting tube 71; the second spring 763 is sleeved on the abutment shaft 761, and one end of the second spring 763 is abutted with the limit ring 762, and the other end is abutted with the limit box 765.

[0039] When it is necessary to pull the back frame 74 to move in the connecting tube 71, first hold the holding block 764 and pull the holding block 764 to move toward the side away from the limit box 765, which will simultaneously drive the abutment shaft 761 away from the back frame 74 and make the abutment shaft 761 completely disengage from the upper abutment hole 741 of the back frame 74, so that the back frame 74 can move up and down in the connecting tube 71, and when the abutment shaft 761 moves, it will drive the limit ring 762 to move The second spring 763 is moved, and the limiting ring 762 squeezes the second spring 763, causing the second spring 763 to be compressed and have an elastic restoring force. After the position of the back frame 74 in the connecting tube 71 is adjusted, it is only necessary to loosen the holding block 764, and the abutment shaft 761 will drive the abutment shaft 761 to reset and abut against the back frame 74 through the second spring 763, and the abutment shaft 761 will be inserted into the abutment hole 741 of the back frame 74, thereby fixing the back frame 74.
