[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, it comprises a base plate 1 on which a walking mechanism 2, a kneading mechanism 3, a knocking mechanism 4, a worm gear 53, a worm 52 and a gearbox 5 are fixedly arranged.

[0027] The walking mechanism 2 includes a walking main shaft 21, a walking secondary shaft 22, a walking motor 23 and a walking positioning circuit board 24. The walking main shaft 21 is rotatably fixed on the base plate 1 and is connected to the walking motor 23. The walking secondary shaft 22 is fixed on the base plate 1. The walking positioning circuit board 24 is fixed on the base plate 1 through a fixing frame 44 and is located above the walking main shaft 21. The walking positioning circuit board 24 is used to control the number of rotations of the walking main shaft 21. Its control method and accessories are not repeated here. Rollers are provided at both ends of the walking main shaft 21 and the walking secondary shaft 22.

[0028] The edge of the bottom plate 1 is formed into a bending rib 11 through a sheet metal stretching process. In this embodiment, the bending rib 11 is perpendicular to the bottom plate 1. Since the bending rib 11 is relatively high, its height is equivalent to the thickness of the bottom plate 1, that is, the effect produced by the bending rib 11 is equivalent to the thickness of the bottom plate 1 being thickened by the same height dimension, thereby improving the rigidity and strength of the bottom plate 1, saving the thickness of the bottom plate 1, and avoiding the deformation of the bottom plate 1 caused by the deformation of other mechanisms installed on the bottom plate 1, thereby avoiding the occurrence of transmission failures. It should be noted here that the bending rib 11 close to the walking auxiliary shaft 22 has the largest height dimension, which maximizes the support force and support strength of the bottom plate 1 at the walking auxiliary shaft 22. In addition, the bending direction of the bending rib 11 can be either one side or both sides, and the bending angle can be selected according to the actual working conditions.

[0029] The traveling secondary shaft 22 is integrated with the base plate 1. In this embodiment, the traveling secondary shaft 22 is directly welded to the end of the base plate 1, so that the traveling secondary shaft 22 and the bending rib plate 11 are integrated. The force borne on the base plate 1 is directly transmitted to the traveling secondary shaft 22, avoiding the loosening of the traveling secondary shaft 22, thereby preventing the entire movement from shaking when running on the track. Compared with other existing base plate 1 structures, the base plate 1 is stronger in rigidity and load-bearing strength, and the structure is simpler and more compact, easy to process, and lower in cost.

[0030] like Figure 3 As shown, the surface of the bottom plate 1 is provided with convex ribs 12 according to the actual stress condition. In this embodiment, the convex ribs 12 protrude toward the side where the crank arm and the swing arm are installed, and the force transmitted from the worm gear 53, worm 52, gearbox 5 to the bottom plate 1 is transmitted to the bending plate ribs and the travel auxiliary shaft 22 through the convex ribs 12. The bearing capacity and anti-bending strength of the bottom plate 1 are increased to the greatest extent. Of course,

[0031] like Figure 2 As shown, the kneading mechanism 3 includes a kneading shaft 31, a crank arm 32 and a swing arm 33. The kneading shaft 31 is connected to the worm gear 53 and the worm 52 gearbox 5. The kneading shaft 31 is sleeved with a crank arm 32, and the crank arm 32 is sleeved with a swing arm 33. The crank arm 32 drives the swing arm 33 to swing.

[0032] like Fig. 9 As shown, a torsion spring 35 is provided between the swing arm 33 and the crank arm 32. One end of the torsion spring 35 is fixed to the side of the crank arm 32, and the other end is against the reset positioning column on the swing arm 33, that is, the reset elastic force comes from the torsion spring 35. The service life of the torsion spring 35 is more than 6 times longer than that of the pull ring, and the resistance is uniform. Usually, the swing arm 33 is made of metal. When the swing arm 33 swings around the crank arm 32, the swing arm 33 will directly impact the crank arm 32. Therefore, a buffer mechanism 36 is provided at the impact point between the swing arm 33 and the crank arm 32, as shown in FIG. Figure 4As shown, the buffer mechanism 36 includes a first pad 361 and a second pad 362. The first pad 361 is fixed to the lower edge of the swing arm 33 through a reset positioning column. Correspondingly, the second pad 362 is fixed to the edge of the curved arm 32 and is located below the first pad 361. When the swing arm 33 swings and collides with the curved arm 32, the first pad 361 and the second pad 362 touch each other, thereby forming an elastic buffer between the swing arm 33 and the curved arm 32 to prevent damage at the contact point between the swing arm 33 and the curved arm 32 and increase the service life.

[0033] The first pad 361 and the second pad 362 can have various shapes and are made of non-metallic materials such as rubber to avoid noise when the two collide. In this embodiment, the contact surface is usually set larger, so that the first pad 361 and the second pad 362 increase the force area when in contact, thereby extending the working life of the two to the greatest extent.

[0034] The crank arm 32 includes a left arm 321 and a right arm 322, which are tightly fixed to each other through a connecting piece. A bearing hole 323 is provided on the left arm 321 and the right arm 322, and the two bearing holes 323 are concentric. The kneading shaft 31 passes through the two bearing holes 323, and the shaft body of the kneading shaft 31 is in direct contact with the bearing surface in the bearing hole 323, so that the crank arm 32 is evenly stressed, the load-bearing capacity is improved, and the friction noise between the bearing and the shaft is reduced.

[0035] In this embodiment, Figure 5 , 6 As shown, a groove 324 is formed at the middle edge of the crank arm 32, and the crank arm 32 also has a through hole 325 penetrating the groove 324. A screw 326 is installed in the through hole 325. The screw 326 passes through the second cushion block 362 and fixes the second cushion block 362 in the groove 324. The second cushion block 362 extends upward to the outside of the groove 324, so that the second cushion block 362 collides with the first cushion block 361 to prevent the crank arm 32 from directly impacting the swing arm 33.

[0036] The striking mechanism 4 includes a striking motor 41 and a striking shaft 42, wherein the striking motor 41 is connected to the striking shaft 42, and the striking shaft 42 is further connected to the crank arm 32 via a ball head rod 45. Figure 1As shown, the front end of the knocking motor 41 is fixed by a bracket 43, and the rear end is fixed by a fixed frame 44. It should be noted here that the fixed frame 44 is a hollow box-shaped structure, which is fixed on the base plate 1, and the walking positioning circuit board 24 is located therein, which is used to protect the walking positioning circuit board 24, and the rear end of the knocking motor 41 is fixedly connected thereto, so that the fixed frame 44 is also used as the end fixing structure of the knocking motor 41, which not only strengthens the stability of the knocking motor 41, but also has multiple uses for one part, making the structure more compact. Since the output shaft of the knocking motor 41 and the knocking shaft 42 are belt-driven, the bracket 43 is in the shape of a belt, so that the output shaft of the knocking motor 41 is balanced, and the fixed frame 44 at the rear end of the knocking motor 41 can withstand the larger impact force generated by the knocking motor 41, so that the belt drive shaft loses parallelism caused by the deformation of the front bracket 43 caused by the force on the rear end of the knocking motor 41 when the knocking motor 41 moves is avoided.

[0037] The worm gear 53 and worm 52 gearbox 5 includes a box body 51 , in which a kneading motor 34 and a worm gear 53 are arranged. The output shaft of the kneading motor 34 serves as the worm 52 and cooperates with the worm gear 53 . The worm gear 53 is connected to the kneading shaft 31 .

[0038] like Figure 7 As shown, the box body 51 includes a box seat 511 and a box cover 512. The worm 52 is located in the box cover 512. The box cover 512 is made of metal, such as aluminum, so that the box body 51 has high strength and avoids deformation after being subjected to force, thereby avoiding dimensional errors, thereby ensuring the stability and service life of the kneading mechanism 3; the box seat 511 serves as a bearing cover for the worm wheel 53. The box seat 511 is made of non-metallic material, such as PP. Since the box seat 511 requires lower precision, the non-metallic material has a certain elasticity, and the parts therein can be directly installed without precision cutting; the box cover 512 and the box seat 511 are fixed by a connecting piece, which is convenient for loading and unloading of parts therein, and the positioning is accurate and firm.

[0039] In addition, in the present embodiment, the box cover 512 serves as the front end cover of the kneading motor 34, so that the box cover 512 and the end face of the kneading motor 34 are directly connected and fixed by fasteners, without having to be fixed by the end cover of the kneading motor 34, which not only saves the motor end cover, but also makes the kneading motor 34 more firmly fixed in the box body 51.

[0040] The kneading shaft 31 and the striking shaft 42 are installed in the box seat 512 to form a whole, forming a triangular structure with the ball head rod 45 and the curved arm 32, thereby improving the stability of the connection between the three.

[0041] like Figure 8As shown, a first magnet 54 is provided on the worm 52, and a first Hall sensor 55 is provided in the box cover 512. The first Hall sensor 55 senses the first magnet 54. The rotation of the worm 52 drives the first magnet 54 to rotate, and the kneading number data is obtained by the number of revolutions of the first magnet 54; and a second magnet 56 is provided on the worm wheel 53. In this embodiment, the second magnet 56 is fixed on the worm wheel 53 near the inner wall of the box seat 511, and a second Hall sensor 57 is provided on the corresponding inner wall of the box seat 511. The second Hall sensor 57 is used to sense the second magnet 56. The rotation of the worm wheel 53 drives the second magnet 56 to rotate. Every time the second magnet 56 approaches the second Hall sensor 57, the second Hall sensor 57 senses the second magnet 56, so that the kneading number can be reset to zero at a fixed point. In addition, the auxiliary parts and processors used for collecting relevant data are not mentioned here.

[0042] The first magnet 54 and the second magnet 56 are both installed in a closed manner in the box body 51, which prevents metal chips of the metal box body 51 from being adsorbed on the magnets and affecting the sensing effect of the Hall sensor, and the two Hall sensors are easy to install and remove.

[0043] It should be noted that the kneading motor 34 is located in the box body 51, and the output shaft of the kneading motor 34 acts as a worm 52 and directly meshes with the worm wheel 53, which greatly shortens the distance from the force point of the worm 52 to the support point of the worm 52, reduces the force deformation of the worm 52, and improves the fatigue life and stability of the entire worm wheel 53 worm 52 gearbox 5.

[0044] The above is an explanation of the preferred embodiments of the present invention, but it cannot be understood as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
