[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "provided with" that may appear should be understood in a broad sense. For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The present invention is further described in detail below in conjunction with the embodiments.

[0025] The specific embodiment of the device for quickly breaking up the scarring block provided by the utility model is as follows:

[0026] See also Figure 1-5 , a device for quickly breaking up scarred blocks, comprises a connecting part 1 connected to an excavator, a transmission shaft 2 and a lower plate 3; the lower plate 3 is located below the connecting part 1, and the transmission shaft 2 is connected between the lower plate 3 and the connecting part 1; a plurality of inverted cones 4 are detachably connected to the lower side of the lower plate 3.

[0027] The connecting part 1 comprises a box body, and an ear plate 101 is arranged on the upper side of the box body, i.e., the upper end of the connecting part 1, and a pin hole 102 is arranged on the ear plate 101. Through the pin hole 102, the positioning pin can be used to connect with the mechanical arm of the excavator, so that the device replaces the bucket of the excavator, and the mechanical arm of the excavator drives the device to move up and down, so that the inverted cone 4 hits the material scabbing fast, so that the scabbing block is broken; such as the scabbing block of aluminum oxide powder, the scabbing block and the like with low hardness.

[0028] The upper part of the transmission shaft 2 slides from the lower wall of the box into the box, and an annular base 11 is provided on the outer side of the transmission shaft 2 in the box, and a spring 12 is connected between the base 11 and the upper wall of the box; an anti-impact gasket 13 corresponding to the transmission shaft 2 is also provided on the lower side of the upper wall of the box, and the anti-impact gasket 13 is a cylindrical rubber sheet; when the excavator mechanical arm drives the device downward, the inverted cone 4 first contacts the scarred block and the material, and then compresses the spring 12. During the compression of the spring 12, the inverted cone 4 breaks the scarred block to avoid strong impact, and finally the upper end of the transmission shaft 2 contacts the anti-impact gasket 13 to prevent the transmission shaft 2 from directly hitting the upper wall of the box and further breaking the scarred block; in this way, during the downward movement of the device, the spring 12 and the anti-impact gasket 13 can effectively provide buffering, reduce impact damage, and reduce the self-damage of the device during impact.

[0029] The shape of the inverted cone 4 includes but is not limited to an inverted cone, an inverted triangular pyramid and an inverted triangular plate; a stud 5 is connected to the upper side of the inverted cone 4, and the lower plate 3 is provided with a plurality of internal threaded through holes threadedly connected to the stud 5. Through the stud 5 and the internal threaded through holes on the lower plate 3, the inverted cone 4 can be disassembled, and after a certain inverted cone 4 is damaged, it can be quickly replaced; it is also convenient to install inverted cones 4 of different specifications according to the size of the material scar block.

[0030] In this embodiment, the inverted cone 4 is an inverted circular cone, and a light hole 6 is provided on the upper part of the inverted cone; since the cone is not easy to rotate, the light hole 6 and a rod-shaped driving structure can be inserted to rotate the conical inverted cone 4, thereby facilitating the loading and unloading of the conical inverted cone 4.

[0031] The inverted cone 4 has at least two different heights; in this embodiment, the height of the inverted cone 4 has two different specifications, which can be inserted into the powder material at different depths, suitable for crushing the scab blocks of the powder material, and improving the crushing effect of the scab blocks of the material. First, the material with a large number of scab blocks is spread flat to a certain thickness, which is greater than the height of the higher inverted cone 4, so that the inverted cone 4 of the device presses down the material and pierces the scab blocks to achieve the crushing of the scab blocks.

[0032] The single-plate structure is prone to deformation and damage during use, and setting a thicker load-bearing plate will increase the weight; therefore, in this embodiment, an upper plate 7 is provided on the upper side of the lower plate 3, a tapered portion 21 is provided at the lower end of the transmission shaft 2, and the lower side of the tapered portion 21 is attached to the upper side of the lower plate 3; a through hole 8 corresponding to the small end of the tapered portion 21 is provided in the center of the upper plate 7; the aperture of the through hole 8 is smaller than the outer diameter of the middle part of the tapered portion 21, and the lower plate 3 and the upper plate 7 are connected by a number of bolts 9.

[0033] The upper plate 7 and the lower plate 3 are both made of stainless steel plates, which are harder, less prone to deformation and have a long service life. The bolts 9 pass through the edges of the upper plate 7 and the lower plate 3, and the ends of the bolts 9 are threadedly connected to nuts, so that the middle parts of the upper plate 7 and the lower plate 3 clamp the conical portion 21, so that the upper plate 7 and the lower plate 3 form an integral connection, enhance the structural strength and reduce deformation.

[0034] A plurality of rubber columns 10 are provided between the upper plate 7 and the lower plate 3. Specifically, the upper ends of the rubber columns 10 are connected to the upper plate 7, and the connection method can be bonding; the lower ends of the rubber columns 10 are against the upper side of the lower plate 3. During installation, as the nut is tightened, the upper plate 7 and the lower plate 3 are connected by the bolt 9, so that the upper plate 7 and the lower plate 3 are relatively close, and the upper plate 7 and the lower plate 3 first squeeze the rubber column 10, and then the upper plate 7 and the lower plate 3 clamp the tapered portion 21 in the middle; the rubber column 10 is in an extruded state between the upper plate 7 and the lower plate 3, and the role of the rubber column 10 is the same as that of the spring washer. The rubber column 10 provides elastic force, which can increase the friction between the nut and the bolt 9 through the upper plate 7, thereby reducing the phenomenon that the bolt 9 is loosened due to vibration during operation. In some other embodiments, a spring washer is provided between the nut on the outside of the bolt 9 and the upper side of the upper plate 7, which can further enhance the anti-loosening effect of the bolt 9.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
