Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-4, the present invention comprises a frame 1, a prime mover 2, a tool apron 4 and a tool apron rotating frame 3; the machine frame 1 is of a cuboid frame structure, the bottom of the machine frame is provided with the idler wheels 11, the machine frame can be pushed to work in gardens, the machine frame does not need to be held by hands, and the labor intensity of gardeners is reduced. The prime motor 2 is arranged at the top of the frame 1, a driving belt wheel 21 is arranged on an output shaft of the prime motor 2, a transmission shaft 12 is arranged on the frame 1, and the transmission shaft 12 is arranged on the frame 1 through a bearing and can rotate relative to the frame 1. The transmission shaft 12 is provided with a belt wheel I13 and a belt wheel II 14, the belt wheel I13 is connected with the transmission shaft 12 through a key, and the belt wheel I13 and the transmission shaft 12 rotate synchronously. The driving belt wheel 21 and the belt wheel II 14 are both double-groove belt wheels, and the belt wheel II 14 is arranged on the transmission shaft 12 through a bearing. The diameters of the two belt grooves of the second belt pulley 14 are different, and the two belt grooves of the driving belt pulley 21 are respectively connected with the belt grooves with the small diameters of the first belt pulley I13 and the second belt pulley II 14 through two belts. The tool apron rotating frame 3 is connected with the transmission shaft 12 through a key and can rotate along with the transmission shaft 12. The prime mover 2 drives the transmission shaft 12 to rotate, and the transmission shaft 12 can drive the tool apron rotating frame 3 to rotate around the transmission shaft 12 through keys. The tool apron rotating frame is provided with a rotating shaft 32 through a bearing, the rotating shaft 32 is provided with a belt wheel III 31 and a belt wheel IV 34, the belt wheel III 31 and the belt wheel IV 34 are respectively connected with the rotating shaft 32 through keys and synchronously rotate with the rotating shaft 32, and the belt wheel III 31 is connected with a large-diameter belt groove of the belt wheel II 14 through a belt.

One end of the tool apron 4 is fixed on the tool apron rotating frame 3. The tool apron comprises a plurality of tool rests 41, the tool rests 41 are connected into a semicircular structure, the adjacent tool rests 41 are connected through two connecting plates 42, and the connecting plates 42 are connected with side plates of the tool rests 41 through bolts. Bolt holes 415 on two side plates of the tool holder 41, which are connected with the connecting plate 42, are kidney-shaped holes, so that the tool holder 41 can be conveniently adjusted to be semicircular. The center of the connecting plate 42 is provided with a fixed shaft on which a transition belt pulley 43 is arranged corresponding to the belt. Because the plurality of tool holders 41 are connected into a semicircular structure, the belt pulleys between two adjacent tool holders 41 are not in the same plane, and the transition belt pulley 43 needs to be in transition steering in the middle part to realize belt transmission. As shown in fig. 5, a rotating shaft 411 is arranged on the tool holder 41, and a double-groove belt pulley 412 is arranged on the rotating shaft 411; the bottom of the tool holder is provided with a movable blade 413 and a fixed blade 414 through four screws.
