When the pushing assembly is in operation, the pushing assembly can push the grass to the right into the elastic cover 6; the pushing assembly includes a telescopic transport roller 146, a belt assembly 147 and a telescopic guide plate 148. The telescopic transport roller 146 is rotatably connected between the lower right sides of the front and rear telescopic plates 4. When the telescopic transport roller 146 is reversed, the telescopic transport roller 146 can drive the cut grass to move to the right, and the front end of the telescopic transport roller 146 is connected to the axle of the front right wheel 5. A belt assembly 147 is connected between the parts, and the belt assembly 147 consists of a large pulley, a small pulley and a flat belt, wherein the large pulley is fixedly mounted on the shaft of the wheel 5, and the small pulley is fixedly mounted on the front end of the telescopic transport roller 146, and the flat belt is wound between the large pulley and the small pulley, and a telescopic guide plate 148 is fixedly connected between the lower right side of the inner side of the front and rear telescopic plates 4, and the telescopic guide plate 148 is located on the right side of the telescopic transport roller 146. The telescopic guide plate 148 is tilted, and the telescopic guide plate 148 can guide the cut grass.

[0033] First, the operator holds the movable frame 1, and then pushes the device onto the lawn through the movable frame 1 and the wheels 5. The rubber sleeve 101 contacts the operator's hand, increasing the friction with the hand, so that the operator can hold the movable frame 1 more firmly. At this time, the electric cutter 12 contacts the grass on the lawn, and then the left and right cylinders 7 are started according to the situation of the lawn. The telescopic rods of the left and right cylinders 7 are extended to drive the front and rear telescopic plates 4 to move outward respectively. The front and rear telescopic plates 4 drive the telescopic nozzle 14, the telescopic material transport roller 146 and the telescopic guide plate 148 to extend. At the same time, the front telescopic plate 4 moves outward to drive the straight hole plate 9 to move forward. The straight hole plate 9 moves forward to drive the contact rod 134 to move downward. The contact rod 134 moves downward to drive the movable tube 13 to move downward. The tube 13 moves downward, driving the trigger frame 131 to move downward. The trigger frame 131 moves downward and drives the n-shaped rod 132 to swing downward through the waist-shaped hole 1321. The n-shaped rod 132 swings downward, driving the swing frame 133 to swing downward. The swing frame 133 swings downward and drives the electric cutter 12 to move left. The electric cutter 12 moves left to adjust the width of the mowing. The electric cutter 12 moves synchronously with the movement of the front and rear telescopic plates 4 to prevent the subsequent operation after the position of the electric cutter 12 is adjusted to collide with the telescopic plates 4 and affect the use. When the electric cutter 12 is adjusted to the required mowing width, the cylinder 7 is closed, and the front and rear telescopic plates 4 stop moving outward. At this time, the telescopic plates 4 are in a suitable position for use, and the telescopic nozzle 14 and the telescopic material transport The roller 146 and the telescopic guide plate 148 stop extending, the front telescopic plate 4 stops driving the straight hole plate 9 to move forward, the straight hole plate 9 stops driving the contact rod 134 to move downward, the contact rod 134 stops driving the movable tube 13 to move downward, and the electric cutter 12 stops moving to the left. Then the electric cutter 12 is started to rotate forward, and the electric shaft 10 is started to rotate forward at the same time. The protective cover 102 protects the upper part of the electric shaft 10 to prevent the electric shaft 10 from being damaged by foreign objects, thereby ensuring the safety of the electric shaft 10. The electric shaft 10 rotates forward to drive the rotating frame 11 to rotate forward, and the rotating frame 11 rotates forward to drive the electric cutter 12 to perform a circular motion. The electric cutter 12 rotates forward and in a circular motion to cut the grass on the lawn. The operator can then use the movable frame 1 The wheel 5 pushes the device to move to the left, which also causes the electric cutter 12 to move to the left to fully mow the grass. During the mowing process, the wheel 5 on the front right reverses to drive the belt assembly 147 to reverse, and the belt assembly 147 reverses to drive the telescopic transport roller 146 to reverse. At the same time, the electric shaft 10 rotates forward and also drives the fan blades 142 to rotate forward. The fan blades 142 rotate forward to blow air into the air outlet pipe 141, and the air outlet pipe 141 discharges the air into the telescopic nozzle 14, and the telescopic nozzle 14 blows the air to the right. The air blown to the right contacts the cut grass, and the air blows the cut grass to the right. The cut grass moves to the right and contacts the telescopic transport roller 146. The telescopic transport roller 146 reverses to push the cut grass to the right, and the cut grass contacts the telescopic guide plate 148.The telescopic guide plate 148 guides the cut grass so that the cut grass enters the elastic cover 6. At the same time, the fan blades 142 rotate forward to exhaust air from the fixed shell 144 and the collection box 2 through the exhaust pipe 143, so that the collection box 2 is in a negative pressure state. The collection box 2 extracts the grass in the elastic cover 6, so that the grass is collected in the collection box 2, which is convenient for subsequent processing of the grass. The mesh plate 145 can block the grass in the collection box 2 to prevent the grass from passing through the fixed shell 144 and entering the exhaust pipe 143 to cause blockage, thereby ensuring the normal use of the exhaust pipe 143. This is repeated, and the grass on the lawn can be continuously cut, and the cut grass can be collected and processed. When all the grass on the lawn is cut, the electric cutter 12 and the electric shaft 10 are turned off, the electric shaft 10 stops driving the rotating frame 11 to rotate forward, the rotating frame 11 stops driving the electric cutter 12 to move in a circle, and the electric shaft 10 also stops driving The fan blades 142 rotate forward, the air stops being discharged into the air outlet pipe 141, the telescopic nozzle 14 stops ejecting air, and at the same time, the fan blades 142 stop exhausting air from the fixed shell 144 and the collecting box 2 through the exhaust pipe 143, stopping the device, the wheels 5 stop reversing, and the wheels 5 stop driving the telescopic transport roller 146 to reverse, and then the left and right cylinders 7 are started to drive the front and rear telescopic plates 4 to move inward and reset, and the front telescopic plate 4 is reset to drive the one-line orifice plate 9 to move backward and reset, and the one-line orifice plate 9 is reset to drive the contact rod 134 to move upward and reset, and the contact rod 134 drives the trigger frame 131 to move upward and reset through the movable tube 13, and the trigger frame 131 drives the n-shaped rod 132 to swing upward and reset through the waist-shaped hole 1321, and the n-shaped rod 132 drives the electric cutter 12 to move right and reset through the swing frame 133. At the same time, the telescopic plate 4 drives the telescopic nozzle 14, the telescopic transport roller 146 and the telescopic guide plate 148 to retract and reset. In this way, by adjusting the position of the telescopic plate 4 and the electric cutter 12, the width of the mowing can be flexibly adjusted to adapt to lawns in different situations, thereby improving adaptability and overall mowing efficiency.

[0034] See also Figure 7 and Figure 8As shown, the lithium-electric lawn mower for garden lawns also includes a blocking assembly installed between the left sides of the front and rear telescopic plates 4. The blocking assembly includes an interception frame 15, an L-shaped block 151, a swing block 152, a connecting spring 153 and a driving assembly. The interception frame 15 is rotatably connected between the lower left sides of the inner sides of the front and rear telescopic plates 4. The front interception frame 15 is slidably connected to the rear interception frame 15. The interception frame 15 can block stones in the lawn. The front side of the front interception frame 15 and the rear side of the rear interception frame 15 are both fixedly connected with the L-shaped block 151, and the lower left side of the outer side of the front and rear telescopic plates 4 is rotatably connected with the swing block 152. The lower left sides of the front and rear swing blocks 152 are respectively connected to the front and rear A connecting spring 153 is connected between the lower part of the right side of the side L-shaped block 151, and a driving assembly is provided between the swing block 152 and the telescopic plate 4. When the driving assembly is in operation, the driving assembly can drive the swing block 152 to swing to the left; the driving assembly includes a button 154 and an electric push rod 155. The lower part of the left side of the front and rear swing blocks 152 is installed with a button 154, and the button 154 corresponds to the L-shaped block 151. The lower left side of the outer side of the front and rear telescopic plates 4 is rotatably connected with an electric push rod 155. The telescopic rod ends of the front and rear electric push rods 155 are respectively rotatably connected to the lower part of the front and rear swing blocks 152, and the electric push rod 155 and the button 154 are electrically connected through the control module.

[0035] When the front and rear telescopic plates 4 move outward, the telescopic plates 4 drive the front and rear intercepting frames 15 to move outward, and then when the telescopic plates 4 stop moving, the telescopic plates 4 stop driving the front and rear intercepting frames 15 to move outward, and when the operator pushes the device to move to the left, the telescopic plates 4 move to the left, driving the front and rear intercepting frames 15 to move to the left, and the front and rear intercepting frames 15 move to the left and move in the grass of the lawn. When the front and rear intercepting frames 15 move to the left and come into contact with stones in the lawn, the intercepting frames 15 block the stones. As the stones are continuously blocked, the weight of the stones squeezes the intercepting frame 15 to swing to the right, and the intercepting frame 15 swings to the right, driving the L-shaped block 151 to swing to the right, and the connecting spring 153 is compressed. When the L-shaped block 151 swings to the right and contacts the button 15 When the L-shaped block 151 contacts the block 154, the L-shaped block 151 presses the button 154, which activates the electric push rod 155 through the control module. The telescopic rod of the electric push rod 155 quickly extends, causing the swing block 152 to swing rapidly to the left. The swing block 152 drives the interception frame 15 to swing leftward via the connecting spring 153. The interception frame 15 swings leftward, quickly pushing away the blocking stone, and the stone breaks contact with the interception frame 15. Due to the action of the connecting spring 153, the interception frame 15 swings back to its original position. The telescopic rod of the electric push rod 15 then shortens, causing the swing block 152 to swing rightward and back to its original position. The swing block 152 drives the interception frame 15 to swing rightward and back to its original position via the connecting spring 153. At this point, the interception frame 15 is in its original position, continuing to block stones on the lawn. When the telescopic plate 4 stops moving leftward, the telescopic plate 4 stops driving the interception frame 15 to move leftward. At the same time, when the front and rear telescopic plates 4 move inward to reset, the telescopic plates 4 drive the front and rear interception frames 15 to move inward and reset, and the grass in the collection box 2 is removed for subsequent processing. In this way, it is possible to prevent stones on the lawn from colliding with the electric cutter 12 and causing damage to the electric cutter 12 , thereby ensuring the safety of the electric cutter 12 .

[0036] See also Figure 9 As shown, the lithium-powered lawn mower for garden lawns also includes a guide frame 16 and a breathable collecting bag 17. The guide frame 16 is fixedly connected to the left side of the collecting box 2, and the breathable collecting bag 17 is clamped on the discharge end of the guide frame 16. The breathable collecting bag 17 can realize the centralized collection of the cut grass.

[0037] When negative pressure is applied to collection box 2, it creates a negative pressure inside breathable collection bag 17, which in turn creates a negative pressure inside guide frame 16. The grass inside elastic cover 6 is drawn into guide frame 16, and the grass inside guide frame 16 is then drawn into breathable collection bag 17. The cut grass is then collected in breathable collection bag 17. Once all the grass on the lawn has been cut, the door of collection box 2 is pulled upward and swung open. Breathable collection bag 17 is then removed from guide frame 16 to empty the cut grass. After all the cut grass has been emptied, breathable collection bag 17 is snapped back onto guide frame 16. This makes collecting the cut grass more convenient.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
