[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0037] See Figure 1-4A land clearing machine equipped with a skid steer loader includes a skid steer loader 1 and a land clearing machine 2, which is installed in front of the skid steer loader 1. The land clearing machine 2 includes a hood 3, a hanging plate assembly 4 on the back of the hood 3, which is fixedly connected to the land clearing machine 1. A cutter shaft roller assembly 5 is rotatably installed inside the hood 3. A drive device 6 is installed on the top of the hood 3. The drive device 6 is connected to the cutter shaft roller assembly 5 by a pulley and a belt. Protective frame assemblies 7 are installed on the left and right sides of the hood 3, extending above the hood 3. An upper fixed blade fixing beam 8 and a lower fixed blade fixing plate 9 are respectively installed inside the hood 3, which are located diagonally above and in front of the cutter shaft roller assembly 5. An adjustable upper fixed blade 10 is installed on the upper fixed blade fixing beam 8, and an adjustable lower fixed blade 11 is installed on the lower fixed blade fixing plate 9. A protective chain 12 is also installed on the back of the hood 3. Specifically, for ease of cutting, sliding plates are installed on both sides of the machine cover 3. When cutting surface materials, the sliding plates on both sides of the shovel contact the ground, and the cutters on the rotating cutter shaft and roller assembly cut the shrubs (trees) on the ground. The cut materials are carried into the machine cover 3 by the rotating rollers and then crushed a second and third time. The crushed materials are then scattered onto the ground from the front. For cutting tall shrubs (trees): the sliding plates on both sides of the shovel are lifted a certain distance from the ground, the loader moves forward, and the upper protective frame of the shovel first contacts the shrubs (trees) and pre-presses them (adjusting the position of the protective frame as needed). Then, the cutters on the rotating cutter shaft and roller assembly directly cut the tall shrubs (trees). The cut materials are thrown backward along the tangent of the rollers (without entering the machine cover). The upper material falls to the ground under the protection of the protective chain, and the lower material is scattered directly onto the ground. The protective chain 12 further prevents the splashes from flying backward, thereby protecting the operators and equipment from injury.

[0038] See Figure 5-6 The cover 3 includes an upper cover plate 31. A left side plate 32 and a right side plate 33 are respectively provided on the left and right sides of the upper cover plate 31. An installation groove 34 is provided on the right side plate 33. Strip holes 35 are provided on the left and right sides of the installation groove 34. The installation groove 34 and the strip holes 35 are used to install the drive device 6 and can adjust the height of the drive device 6.

[0039] See Figure 5 The mounting plate assembly 4 includes a main mounting plate 41, with mounting side plates 42 on both the left and right sides of the main mounting plate 41. An upper rectangular tube 43 and a lower rectangular tube 44 are positioned between the mounting side plates 42. A pin plate 45 is positioned below the lower rectangular tube 44, and pin holes 46 are formed on both the left and right sides of the pin plate 45. The surfaces of the upper rectangular tube 43, the lower rectangular tube 44, and the pin plate 45 form a mounting surface. Aligning the upper part of the mounting bracket at the front of the loader with the mounting surface of the mounting plate at the rear of the land clearing machine, and inserting the pin holes 46, completes the mounting.

[0040] See Figure 7-8The drive unit 6 includes a hydraulic motor 61. A connecting shaft 62 is installed on the output shaft of the hydraulic motor 61. The connecting shaft 62 passes through the mounting groove 34 and is fixedly connected to the pulley. A transition plate 63 is installed on the front end face of the hydraulic motor 61. Mounting holes (not shown in the figure) are provided on the left and right sides of the transition plate 63. The mounting holes match the strip holes 35 and are fixed by bolts. A fixing seat 64 is installed below the mounting groove 34. An adjusting screw 65 is installed on the longitudinal thread of the fixing seat 64. A locking nut 66 is also installed on the adjusting screw 65. The top of the adjusting screw 65 abuts against the bottom of the hydraulic motor 61. Start the skid steer loader 1 and operate the hydraulic output handle of the loader. The hydraulic oil output from the loader enters the hydraulic motor 61 of the scavenger. The oil drives the hydraulic motor to rotate. The hydraulic motor drives the connecting shaft 62 and the pulley to rotate. The pulley drives the cutter shaft roller assembly 5 to rotate through the belt. After the three hydraulic quick couplings (oil inlet, oil return, and oil unloading) of the scavenger are connected to the hydraulic output of the skid steer loader 1, the installation is completed.

[0041] See Figure 9 The cutter shaft roller assembly 5 includes a cutter shaft roller 51, with anti-winding rings 52 and bearing seats 53 at the left and right ends of the cutter shaft roller 51, respectively. One of the bushings is equipped with a driven pulley 54. A cutter head 55 is spirally arranged on the surface of the cutter shaft roller 51. The cutter head 55 is made of high-strength wear-resistant mold steel and includes four cutting edges. The cutter head 55, made of high-strength wear-resistant mold steel, can cut materials such as wood, plastic, metal, and rubber. It is sturdy and durable, not easily damaged, and has a long service life. The cutter head 55 is fixedly connected with bolts, facilitating future replacement.

[0042] See Figure 10-11 The protective frame assembly 7 includes a pair of left pull rods 71 ​​and a right pull rod 72 located on the left and right sides of the machine cover 3. The left pull rods 71 ​​and right pull rods 72 are fixed to the machine cover 3 with bolts and nuts.

A crossbar 74 is set between the mounting plates 73, and an adjustment handle 75 is set on the mounting plates 73. The protective frame assembly 7 is installed on the shovel loader. When cutting tall shrubs (trees), the protective frame assembly 7 pre-presses the shrubs (trees) to be cut forward to prepare for the cutter head. During the cutting process, the protective frame assembly 7 pushes the cut shrubs (trees) forward to prevent the cut material from falling onto the skid loader, thereby causing equipment damage or operator injury. The bottom and top of the left pull rods 71 ​​and right pull rods 72 can be adjusted in angle with bolts and nuts, and then the bolts and nuts are fixed.

[0043] See Figure 12The upper fixed blade 11 and the lower fixed blade 12 have the same structure, with multiple oblong holes 13 evenly spaced on their surfaces. The upper and lower fixed blades each have four cutting edges. Through the oblong holes 13, the gap between the upper cutter head 55 and the lower fixed blade in the cutter shaft roller assembly 5 is adjustable (5-35mm), while the gap between the upper fixed blade and the cutter head is fixed (optional as needed). The upper and lower fixed blades and the cutter head can all use four cutting edges, greatly improving the service life of the fixed blades and the cutter head.
