DETAILED DESCRIPTION

[0023] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0024] Please refer to Figs. 1 to 4 The soil loosening bucket for hydraulic excavator in the embodiment comprises a control arm 1 of the excavator, a bucket body 2 fixedly installed on the output end of the control arm 1 of the excavator, and a plurality of bucket teeth 3 fixedly connected to the outside of the bucket body 2. The inside bottom wall of the bucket body 2 is fixedly installed with a driving box 4. The inside of the driving box 4 is provided with a crushing mechanism 5 extending to the outside thereof. The outside of the bucket body 2 is provided with a scattering mechanism 6 extending to the inside thereof. The crushing mechanism 5 comprises a rotating seat 51 fixedly connected to the inside bottom wall of the driving box 4, a connecting plate 52 rotatably connected to the upper surface of the rotating seat 51, a fixed plate 53 fixedly connected to one side of the connecting plate 52, a plurality of crushing teeth 54 fixedly connected to one side of the fixed plate 53, and a driving mechanism arranged in the inside of the driving box 4.

[0025] The connecting plate 52 is swingably connected to the inside of the driving box 4. The inside of the driving box 4 is provided with a movable port matched with the fixed plate 53 and the plurality of crushing teeth 54. The inside of the movable port is fixedly installed with a sealing gasket matched with the fixed plate 53. The sealing gasket can prevent the soil from entering the inside of the driving box 4 during the crushing process, thereby maintaining the normal operation of the driving mechanism and ensuring the continuity and stability of the soil loosening.

[0026] Specifically, the plurality of crushing teeth 54 are distributed at equal intervals on the outside of the fixed plate 53 in sequence, and the plurality of crushing teeth 54 and the plurality of bucket teeth 3 are distributed in an upper and lower staggered manner.

[0027] It should be noted that the driving mechanism includes a driving motor 55 fixedly installed on the bottom wall in the driving box 4, a rotating disc 56 fixedly connected to the output shaft of the driving motor 55, a pulley 57 rotatably installed on the outer surface of the rotating disc 56, and a connecting groove 58 opened in the inside of the connecting plate 52. The connecting plate 52 is swingably connected to the outer surface of the rotating disc 56 through the connecting groove 58, and the pulley 57 is in sliding connection with the connecting groove 58. The driving motor 55 is started by the controller to drive the rotating disc 56 to rotate, thereby driving the pulley 57 to slide in the connecting groove 58, so that the connecting plate 52 and the fixed plate 53 and the crushing teeth 54 thereon can reciprocate left and right, so that the crushing teeth 54 can more effectively contact the soil, thereby improving the efficiency of soil loosening. By arranging the crushing teeth 54 and the bucket tooth 3 in an upper and lower staggered distribution, the movement track of the crushing teeth 54 in the soil is more complex and variable, which can better break and loosen the hard parts in the soil, improve the overall loosening effect of the soil, and achieve the advantage of high soil loosening efficiency.

[0028] In the embodiment, the scattering mechanism 6 includes a hollow shaft 61 rotatably connected to the inside of the bucket body 2 and extending to the outside thereof, stirring blades 62 fixedly connected to the outside of the hollow shaft 61, air outlet holes 63 opened in the inside of the hollow shaft 61, an air inlet hose 64 rotatably connected to the end of the hollow shaft 61 away from the bucket body 2, and a transmission mechanism arranged outside the bucket body 2.

[0029] The number of the stirring blades 62 is several, and the several stirring blades 62 are distributed at equal intervals on the outside of the hollow shaft 61 in sequence. The number of the air outlet holes 63 is several, and the several air outlet holes 63 are distributed at equal intervals on the outer surface of the hollow shaft 61 in sequence.

[0030] Specifically, the transmission mechanism includes a speed reducer 65 fixedly installed outside the bucket body 2, a worm 66 fixedly connected to the output shaft of the speed reducer 65, and a worm wheel 67 fixedly connected to the outside of the hollow shaft 61. The worm 66 and the worm wheel 67 are in meshing engagement. The speed reducer 65 is started to work by the controller to drive the worm 66 to rotate, thereby driving the worm wheel 67 and the hollow shaft 61 to rotate, so that the stirring blades 62 rotate to stir the soil. This stirring mode can more effectively disperse the soil particles, thereby improving the loosening efficiency of the soil. When the hollow shaft 61 rotates, the air inlet hose 64 can input gas into the inside of the hollow shaft 61. The gas is sprayed out through the air outlet holes 63 to produce a blowing effect on the soil, which can further increase the loosening degree of the soil and make the soil more loose.

[0031] It should be noted that the outside of the bucket body 2 is detachably provided with a protective cover 68. The outer diameter of the transmission mechanism is matched with the inner diameter of the protective cover 68. A rotating hole matched with the air inlet hose 64 is opened in the inside of the protective cover 68, and a protective pad matched with the air inlet hose 64 is fixedly installed in the inside of the rotating hole.

[0032] The working principle of the above embodiment is as follows:

[0033] In use, the driving motor 55 is started by the controller to drive the rotating disc 56 to rotate, and then the pulley 57 is driven to slide in the connecting groove 58, so that the connecting plate 52 and the fixed plate 53 and the crushing teeth 54 thereon can reciprocate left and right, so that the crushing teeth 54 can be more effectively contacted with the soil, thereby improving the efficiency of soil loosening; at the same time, the speed reducer 65 is started by the controller to drive the worm 66 to rotate, and then the worm wheel 67 and the hollow shaft 61 are driven to rotate, so that the stirring blade 62 rotates to stir the soil. This stirring mode can more effectively disperse the soil particles. When the hollow shaft 61 rotates, the air inlet hose 64 can input gas into the hollow shaft 61, and the gas is sprayed out through the air outlet hole 63 to produce a blowing effect on the soil.

[0034] The mounting mode, connecting mode or setting mode disclosed in the embodiment are all common mechanical connection modes, and as long as the beneficial effects can be achieved, they can be implemented. In addition, the electrical elements appearing in the embodiment are all electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. A person skilled in the art can control the electrical elements through simple programming, and the existing disclosed power connection technology also belongs to the common knowledge in the art. Therefore, the specific structure composition and working principle of the embodiment will not be described in more detail.
