[0027] Referring to Figures 1-5 As shown, a wet material crushing and suction gun includes a mounting base 1, a support base 2, a servo motor 3, a main shaft 4, a coupling 5, a suction pipe 6, a discharge pipe 7 and a crushing blade 8. The servo motor 3 is provided at the upper end of the mounting base 1, the support base 2 is provided at the side of the mounting base 1, the suction pipe 6 is connected to the lower end of the mounting base 1, the main shaft 4 passes through the mounting base 1 and is connected to the servo motor 3 through the coupling 5, the discharge pipe 7 is connected to the upper side of the upper end of the suction pipe 6, and the crushing blade 8 is provided at the lower port of the suction pipe 6 and is connected to the main shaft 4.

[0028] The main shaft 4 of the crushing and suction gun is connected to the servo motor 3 through the coupling 5. The crushing blade 8 is installed at the bottom of the main shaft 4 to crush the material by rotation for convenient suction of the material; the main shaft 4 in the suction pipe 6 is fixed by the mounting base 1 to prevent the main shaft 4 from shaking during crushing rotation, which may cause damage to it and reduce the working efficiency of the crushing suction gun; the discharge pipe 7 forms a negative pressure through the connected equipment to suck the material.

[0029] Further, the included angle between the discharge pipe 7 and the upstream section of the suction pipe 6 is 120° - 160°. Preferably, it is 150°.

[0030] If the angle is too small, it will be disadvantageous for discharging the material, while if the angle is too large, it will be disadvantageous for the discharging pipe 7 to be connected with other equipment through structures such as chucks.

[0031] Furthermore, an air supply hole 61 is provided on the tube wall of the suction tube 6 .

[0032] The air holes 61 are for air flow when sucking materials, so as to better drive the material to be sucked in. If all the materials are sucked in, there may be a material blockage. The air holes 61 cannot be too large, otherwise it will affect the negative pressure effect, so the holes should be small and numerous.

[0033] Furthermore, the upstream side of the air supplement hole 61 is recessed inwards.

[0034] The upstream end side of the air replenishing hole 61 is recessed inwardly, which can prevent the material from being squeezed out of the air replenishing hole 61, and can also increase the air replenishing effect and avoid being blocked when the material is sucked.

[0035] Furthermore, the crushing blade 8 is inclined downward.

[0036] The contact area between the broken blade and the material is increased, and the material is also prevented from being thrown out of the suction pipe 6 as much as possible.

[0037] Furthermore, the inclination angle of the crushing blade 8 is 30°-60°, preferably 45°.

[0038] Furthermore, a blade edge 81 is provided on the outer side of the crushing blade 8 .

[0039] The outer side is provided with a blade 81 so that the material moves inwards during cutting.

[0040] Furthermore, a feeding notch 62 is provided on the lower end side of the suction pipe 6 .

[0041] On the one hand, it is to prevent the suction pipe 6 from being adsorbed on the barrel, and on the other hand, it is conducive to feeding and prevents the material from being thrown out.

[0042] Furthermore, the feed notch 62 is in an arch shape.

[0043] The feeding is convenient, the structure is firm, and the blocking area is increased.

[0044] Furthermore, the crushing blades 8 are provided with two groups, and the two groups of crushing blades 8 are symmetrically arranged at the lower end of the main shaft 4.

[0045] Realize secondary cutting and crushing of materials to improve crushing effect.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
