DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] Embodiment 1

[0018] Please refer to Figs. 1-3 The embodiment provides a reversing structure for adjusting the working direction of a weeding machine, comprising an engine 101, a driving component 102 and an output component 103, the engine 101 is connected with the driving component 102, the driving component 102 is connected with the output component 103, and the driving component 102 is arranged at the central position inside the weeding machine.

[0019] The drive unit 102 has an upper cover 2 and an output housing 5 inside. The upper cover 2 is located above the output housing 5, and a shift rocker arm 1 and a reversing fork 3 are installed inside the upper cover 2. The output housing 5 has a four-wheel drive No. 9 main gearbox 6 inside, which provides a gear shifting function for the lawnmower drive unit. The four-wheel drive No. 9 main gearbox 6 has an output shaft 7 and an output drive bevel gear 4 inside, and both the output shaft 7 and the output drive bevel gear 4 are installed in conjunction with the output end of the engine 101.

[0020] A reversing bushing 11 is coaxially fitted on the output shaft 7. A meshing sleeve 12 and a retaining ring 9 are respectively fitted on both sides of the reversing bushing 11. The reversing passive bevel gear 10 is fitted with the output shaft 7.

[0021] The shift rocker arm 1 is configured to cooperate with the engagement sleeve 12, and the lower part of the shift rocker arm 1 is connected to the reversing fork 3.

[0022] The reversing fork 3 is mounted on the fork shaft 8, and the fork shaft 8 is positioned parallel to the output shaft 7.

[0023] The specific working steps of this device are as follows:

[0024] During operation, the weed cutter is powered by engine 101. Power is transmitted through the output shaft 7 inside the four-wheel drive main gearbox 6, which engages with the output drive bevel gear 4, to the output housing 5. From there, the power is transmitted to the output component 103. The reversing fork 3 is mounted on the fork shaft 8, and its left and right movement and positioning are achieved by the rotation of the shift rocker arm 1. Figs. 1-2 As shown, the reversing fork 3 is in the neutral position. At this time, the reversing driven bevel gear 10 rotates freely on the output shaft 7, and the output speed is zero, which is neutral. The shift rocker arm 1 rotates and pushes the engagement sleeve 12 to the right. The reversing bushing 11 and the output shaft 7 are engaged through the engagement sleeve 12, thereby driving the output shaft 7 to rotate forward. When the shift rocker arm 1 rotates and pushes the engagement sleeve 12 to the left, the left reversing bushing 11 and the output shaft 7 are engaged through the engagement sleeve 12, thereby driving the output shaft 7 to rotate in reverse.
