DETAILED DESCRIPTION

[0029] The present invention is described in detail below in conjunction with the accompanying drawings:

[0030] like Figure 1-6 As shown, a suction device mainly includes a frame 1, a moving component 2, a swing component 3, a lifting component 4, a suction head 5 and a negative pressure machine;

[0031] The frame 1 is fixed with a pair of transverse guide rails 12 extending in the transverse direction and arranged at intervals in the longitudinal direction. Below the gap between the two transverse guide rails 12 is a material suction station 11 for placing a material loading frame a for material suction work;

[0032] The moving assembly 2 includes a moving vehicle 21 connected to the transverse guide rail 12 in a transverse reciprocating sliding manner and a moving driving component 22 for driving the moving vehicle 21 to move transversely. A longitudinal guide rail 23 extending in the longitudinal direction is fixedly provided on the moving vehicle 21.

[0033] The swing assembly 3 includes a swing frame 31 connected to the longitudinal guide rail 23 in a longitudinal reciprocating sliding manner and a swing driving component 32 for driving the swing frame 31 to move longitudinally;

[0034] The lifting assembly 4 includes a lifting frame 41 slidably connected to the swing frame 31 in the vertical direction and a lifting driving component 42 for driving the lifting frame 41 to move up and down. The suction head 5 is fixed at the bottom of the lifting frame 41 and can extend into the material loading frame a to perform suction. The suction head 5 is connected to the material storage container through a connecting pipe 6, and the negative pressure machine is connected to the connecting pipe 6 to provide it with the suction force required for suction.

[0035] Preferably, a rack 13 is provided above the transverse guide rail 12 and is arranged parallel to the transverse guide rail 12, and the lower surface of the rack 13 is provided with matching teeth arranged in sequence in the transverse direction;

[0036] The mobile vehicle 21 includes a vehicle body 211 and rollers 212 disposed on both sides of the vehicle body 211 in the longitudinal direction. The rollers 212 are rotatably connected to the vehicle body 211 and are rollingly mounted on the corresponding guide rails 12.

[0037] The mobile driving component 22 includes a rotating shaft extending longitudinally and rotatably connected to the vehicle body 211, a first gear 221 fixedly installed at both axial ends of the rotating shaft, and a transmission mechanism installed on the vehicle body 211 for driving the rotating shaft to rotate, wherein the first gear 221 is located below the corresponding rack 13 on the same side and meshes with it for transmission.

[0038] Preferably, the swing driving component 32 is a longitudinal movement driving module installed on the moving vehicle 21 and connected to the swing frame 31 for driving the swing frame 31 to move longitudinally back and forth.

[0039] Preferably, the lifting frame 41 is slidably connected to the swing frame 31 via a vertical slide rail 43 extending along the vertical direction.

[0040] Preferably, the lifting drive component 42 includes a vertical rack 421 installed on the lifting frame 41 and extending in the vertical direction, a lifting drive group 422 installed on the swing frame 31, and a second gear 423 installed on the output shaft of the lifting drive group 422 and coordinated with the vertical rack 421 for transmission.

[0041] like Figure 1 , 4 -5, in order to facilitate the absorption of materials, the lower end of the suction head 5 is divided into a hollow tube body 51 extending in the vertical direction, the lower end opening of the tube body 51 is a suction port, and the tube walls on both sides of the tube body 51 are provided with notches 52 which are connected to the inside and outside of the tube body 51 in the horizontal direction, and the lower end of the notch 52 is connected to the suction port, and the outer side of the notch 52 is provided with a lifting baffle 53 which is slidably connected to the tube body 51 in the vertical direction for opening and closing the notch 52, and the tube body 51 is also provided with a cylinder 54 for driving the corresponding lifting baffle 53 to lift and lower. The cylinder 54 is fixedly installed on the outer side of the tube body 51 and is located above the lifting baffle 53, and the piston rod end of the cylinder 54 is connected to the lifting baffle 53.

[0042] Since shell powder is difficult to absorb, two sets of lifting baffles 53 are provided on the suction head 5 in this embodiment, and they are used together to improve the suction force. When the suction head 5 is moving forward in one direction, the front lifting baffle 53 is raised, and the rear lifting baffle 53 is lowered. When the suction head 5 is moving backward, the rear lifting baffle 53 is raised, and the front lifting baffle 53 is lowered. Conventional suction heads are only provided with an opening at the lower end, and materials can only be fed through the lower opening. The suction head is easy to push the materials to the surroundings during the forward process, especially when it reaches the bottom, the materials are difficult to absorb. However, in the suction head of this embodiment, the front lifting baffle 53 is raised and opened during the forward process, and the materials can also be fed through the front side, not limited to the bottom feeding, so as to improve the material absorption range.

[0043] Preferably, the suction device is further provided with a control device for connecting to the two cylinders 54 and the mobile driving component 22 respectively so as to control the coordinated actions of the cylinders 54 and the mobile driving component 22 .

[0044] like Figure 6 In order to prevent the material from accumulating in the connecting pipe, a plurality of nozzles 61 are arranged at intervals along the length extension direction of the connecting pipe 6 at the bottom of the connecting pipe 6 which is partially in a horizontal or inclined state, and the outlet of the nozzle 61 is connected to the inside of the connecting pipe 6, and each nozzle 61 is connected to the air supply device through a pipeline 62. Since shell powder is easy to accumulate in the connecting pipe 6, the nozzle 61 is arranged at the bottom of the connecting pipe 6 to frequently inflate, which can solve the problem of material accumulation.

[0045] The working principle of this embodiment is as follows:

[0046] The material loading frame a passes through the suction station 11 in sequence along the preset direction. When the material loading frame a is in place, the moving component 2 continues to move forward along the lateral extension direction of the lateral guide rail 12, driving the suction head 5 to continue to suck materials in the lateral direction. When the suction head 5 moves to the end, the swinging component 3 drives the suction head 5 to change position in the longitudinal direction. As the moving component 2 retreats from front to back, it continues to move until the material is sucked. A lifting component 4 is also provided in the swinging component 3 to drive the suction head 5 to move up and down to adapt to the suction of materials at different heights.

[0047] Although the present invention is illustrated and described by specific embodiments and their alternatives, it should be understood that various changes and modifications can be implemented without departing from the spirit and scope of the present invention. Therefore, it should be understood that the present invention is not limited in any sense except by the limitations of the attached claims and their equivalents.
