[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, the technical solution adopted by the utility model is as follows: the excavator shredder includes a seat plate 2, an ear seat 1 is fixedly arranged on the top of the seat plate 2, the ear seat 1 is connected to an external excavator, and the external excavator serves as a driving source of the seat plate 2.

[0021] A rotating shaft is rotatably arranged in the base plate 2 , a tool assembly 15 and a first bevel gear 16 are fixedly arranged on the outer surface of the rotating shaft, and a driving mechanism for driving the rotating shaft to rotate is arranged in the base plate 2 .

[0022] The tool assembly 15 includes a plurality of blades distributed along the circumference of the shaft, and the blades can extend along the axial direction of the shaft, or extend in a spiral shape with the shaft as the axis. The shape of each blade can be sawtooth, triangle, trapezoid, etc.

[0023] The driving mechanism includes a first motor 3. Two reinforcing plates 18 are fixedly arranged on the seat plate 2. The first motor 3 is fixedly mounted on one of the reinforcing plates 18. The output shaft of the first motor 3 is fixedly connected to the rotating shaft. The end of the rotating shaft away from the first motor 3 rotates and passes through the other reinforcing plate 18.

[0024] The support plate 10 is fixedly arranged on the seat plate 2. The support plate 10 is composed of two mutually perpendicular sub-plates, one of which is parallel to the rotating shaft, and the other is arranged along the radial direction of the rotating shaft. A shaft rod 4 is rotatably arranged between the sub-plate parallel to the rotating shaft and the seat plate 2. One end of the shaft rod 4 is rotatably connected to the sub-plate parallel to the rotating shaft, and the other end is rotatably connected to the seat plate 2. In addition, the central axis of the shaft rod 4 is perpendicular to the central axis of the rotating shaft.

[0025] The outer surface of the shaft 4 is fixed with a second bevel gear 5, which is meshed with the first bevel gear 16. The shaft 4 is provided with a reciprocating thread 9, which is threadedly connected with a slider 11. The slider 11, the reciprocating thread 9 and the ball form a ball screw pair.

[0026] One side of the slider 11 is in limited sliding engagement with the support plate 10 arranged radially along the rotating shaft, and two sleeves 13 are fixedly provided on the other side of the slider 11. The two sleeves 13 rotate and penetrate the same long rod 12, and each sleeve 13 is provided with a limiting component.

[0027] The position limiting assembly includes two positioning beads (not shown in the figure), and the two positioning beads are fixedly mounted on the inner wall of the sleeve 13. The long rod 12 is provided with two clamping holes (not shown in the figure) corresponding to the two positioning beads in the same position limiting assembly. Each positioning bead is clamped and matched with the corresponding clamping hole, which is used for limiting the position of the long rod 12.

[0028] A shifting rod 14 is fixedly disposed on the long rod 12 . The shifting rod 14 is located between the two sleeves 13 . Spline shafts 17 are fixedly disposed at both ends of the long rod 12 .

[0029] The mounting block 6 is fixedly arranged in the seat plate 2, and the mounting block 6 and the dividing plate parallel to the rotating shaft of the support plate 10 are provided with an adjustment assembly for rotating the lever 14 through the spline shaft 17. The two adjustment assemblies correspond to the two spline shafts 17 one by one.

[0030] The two adjustment components both include a second motor 7, one of which is fixedly mounted on the mounting block 6, and the other second motor 7 is fixedly mounted on the support plate 10 and the split plate parallel to the rotating shaft. The output shafts of the two second motors 7 are both fixedly provided with a spline sleeve 8, and the two spline sleeves 8 are matched with the two spline shafts 17 in a one-to-one manner. It is convenient to adjust the rotation angle of the lever 14, and after adjustment, it is positioned by the limit assembly.

[0031] Working principle: The crusher is connected to the arm of an external excavator through the ear seat 1, and the crusher is pushed forward by the external excavator. The first motor 3 is started, and the output shaft of the first motor 3 drives the cutter assembly 15 and the first bevel gear 16 to rotate through the rotating shaft. The rotation of the cutter assembly 15 will crush and cut the bushes.

[0032] The first bevel gear 16 rotates through the second bevel gear 5 to drive the shaft 4 to rotate, and the shaft 4 rotates through the reciprocating thread 9 to drive the slider 11 to slide back and forth along the central axis of the shaft 4. During the sliding process of the slider 11, the sleeve 13, the long rod 12, the spline shaft 17 and the lever 14 will be driven to slide synchronously.

[0033] In the initial state, the slider 11 is located at the position of the reciprocating thread 9 closest to the tool assembly 15. At this time, the spline shaft 17 facing the mounting block 6 is connected to the spline sleeve 8 on the mounting block 6, and the lever 14 is in a vertical upward state. In addition, each set of limiting components has a positioning bead stuck in a clamping hole, completing the limit of the sleeve 13 on the lever 14.

[0034] As the first motor 3 is started, the slider 11 slides with the lever 14 in a direction away from the cutter assembly 15 , and the lever 14 in a vertical state will not push the bushes away from the cutter assembly 15 .

[0035] When a portion of the spline shaft 17 facing away from the mounting block 6 is engaged in the spline sleeve 8 on the support plate 10, the second motor 7 on the support plate 10 is started, and the second motor 7 drives the spline sleeve 8 connected thereto to rotate, thereby driving the long rod 12 to rotate through the spline shaft 17. The rotation of the long rod 12 will release the limit of the limit assembly on the lever 14, thereby driving the lever 14 to rotate. When the lever 14 rotates to a horizontal state, the second motor 7 is stopped, and at this time, another positioning bead in each limit assembly is stuck in another clamping hole, and the limit of the sleeve 13 on the lever 14 is completed again.

[0036] When the lever 14 rotates to a horizontal state, the slider 11 just drives the lever 14 to slide in the direction close to the tool assembly 15. During the sliding process of the lever 14, more bushes will be pushed toward the tool assembly 15, thereby increasing the degree of squeezing of the bushes on the tool assembly 15, thereby improving the overall cutting and crushing efficiency.

[0037] When a portion of the spline shaft 17 facing the mounting block 6 is reconnected to the spline sleeve 8 on the mounting block 6, the second motor 7 on the mounting block 6 is started, and the second motor 7 drives the spline sleeve 8 connected thereto to rotate, thereby driving the long rod 12 to rotate through the spline shaft 17. The rotation of the long rod 12 will release the limit of the limit assembly on the lever 14, thereby driving the lever 14 to rotate. When the lever 14 rotates to a vertical upward state, the second motor 7 is stopped, and the limit assembly limits the lever 14 again.

[0038] Repeat the above operation to improve the crushing efficiency of the brush crusher.
