The outer wall of the suction nozzle has a spherical structure, and the interior of the suction nozzle is connected to the support tube. A suction port is provided at the bottom of the suction nozzle; multiple outwardly protruding pads are fixedly provided on the outer wall of the suction nozzle; the vibrating motor is located above the suction nozzle and is installed on the support tube.

[0007] In a preferred embodiment of this invention, the suction port has a cross-shaped structure; a first pad is fixedly provided on the outer wall of the suction nozzle at the corner of the outer contour of the suction port.

[0008] In a preferred embodiment of this invention, a plurality of second pads are fixedly arranged in a circumferential array around the axis of the support tube at the bottom of the outer wall of the suction nozzle; the bottom of the second pads is higher than the top of the suction port opening; a plurality of third pads are fixedly arranged in a circumferential array around the axis of the support tube at the middle of the outer wall of the suction nozzle, the number of third pads being twice the number of second pads, and the third pads being staggered and spaced apart from the second pads; a plurality of fourth pads are fixedly arranged in a circumferential array around the axis of the support tube at the top of the outer wall of the suction nozzle, and the fourth pads are symmetrically arranged with respect to the horizontal center plane of the suction nozzle with respect to the second pads.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides a suction head for pneumatic conveying of powder materials, including a main body and a vibrating motor.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 , Figure 2 As shown in the figure, a specific embodiment of the present invention discloses a suction head for pneumatic conveying of powder, including a main body 100 and a vibration motor 200; the main body 100 includes a support tube 110, and a suction nozzle 120 is fixedly provided at the bottom end of the support tube 110. The outer wall of the suction nozzle 120 has a spherical structure, and the interior of the suction nozzle 120 is connected to the support tube 110. A suction port 130 is provided at the bottom of the suction nozzle; a plurality of outwardly protruding pads are fixedly provided on the outer wall of the suction nozzle; the vibration motor 200 is located above the suction nozzle 120 and is installed on the support tube 110.

[0025] The aforementioned suction head for pneumatic conveying of powder, through its spherical structural design, reduces the probability of the suction head penetrating deep into the material, thereby lowering the probability of blockage.

[0026] The vibrating motor position loosens the material through vibration, further preventing blockage and maintaining smooth material conveying;

[0027] Furthermore, the outer wall of the suction nozzle is fixed with multiple outward-protruding pads, which can provide support to a certain extent, increase the probability of a gap between the outer wall of the suction nozzle and the material, and also allow a gap between the nozzle and the inner wall of the hopper, maintaining smooth airflow and thus ensuring smooth material suction.

[0028] Furthermore, such as Figure 3 As shown, the suction port 130 has a cross-shaped structure, and the outer wall of the suction nozzle 120 is fixedly provided with a first pad 141 at the corner of the outer contour of the suction port 130. The cross opening can expand the extension range of the suction port and leave space for the first pad to be set, so that it can be better purged and supported, which can facilitate the flow of gas. Especially when the powder inside the silo falls to the bottom of the silo, it will not be blocked by the inner wall of the silo, so that the material at the bottom can also be sucked up, reducing the residue.

[0029] Furthermore, such as Figures 3 to 5As shown, the bottom of the outer wall of the suction nozzle 120 is fixedly provided with multiple second pads 142 arranged in a circumferential array around the axis of the support tube; the bottom end of the second pads 142 is higher than the top end of the opening of the suction port 130; the middle of the outer wall of the suction nozzle 120 is fixedly provided with multiple third pads 143 arranged in a circumferential array around the axis of the support tube, the number of third pads 143 is twice the number of second pads 142, and the third pads 143 and the second pads 142 are arranged in a staggered and alternating manner; the top of the outer wall of the suction nozzle 120 is fixedly provided with multiple fourth pads 144 arranged in a circumferential array around the axis of the support tube, the fourth pads 144 and the second pads 142 are arranged in a staggered and alternating manner. Block 142 is symmetrically positioned about the horizontal center of the suction nozzle 120; the placement of pads at multiple locations effectively expands the range of external support, further increases the area of ​​overhead support, and improves airflow, thereby maintaining smooth material conveying; and since most of the suction pipes use flexible hoses, the placement of pads at multiple points ensures that even if the suction head faces different locations, the corresponding pads can provide appropriate overhead support and ventilation; even if the suction nozzle is covered by accumulated material, the overhead pads, combined with the vibration of the vibrating motor, can effectively accelerate the clearing of blockages, thereby effectively preventing blockages and maintaining smooth material conveying.

[0030] Furthermore, the first pad 141, the second pad 142, the third pad 143, and the fourth pad 144 are all convex spherical structures, which can provide support and support, allow more flow space, facilitate the smooth passage of materials, and maintain smooth material conveying.

[0031] Furthermore, the top of the suction nozzle 120 is provided with at least one air inlet 150 that communicates with the interior; during normal operation, the suction head is placed in a downward position most of the time, and the air inlet provides an additional air intake point for air replenishment to maintain smooth material conveying.

[0032] Furthermore, such as Figure 3 , Figure 4 As shown, a support frame 160 is fixedly provided on the outer wall of the support tube 110. The support frame 160 has grooves 161 on opposite sides. The vibratory motor 200 is installed in the grooves 161 by screws. A protective cover 300 is fitted on the outside of the support frame 160. The protective cover 300 is installed on the support frame 160 by screws to cover and shield the grooves 161. The support frame and grooves provide a mounting position for the vibratory motor, and the use of two vibratory motors can provide sufficient vibration effect. The protective cover can shield and protect the vibratory motor, preventing it from being exposed to the dusty working space, preventing it from being easily damaged, and extending its service life.

[0033] Furthermore, the top of the groove is provided with a through hole extending to the outside of the support frame. A wire plug is installed at the through hole, and the wiring of the vibration motor extends to the outside through the wire plug. The wire plug seals this part, effectively preventing external dust from entering the interior.

[0034] Furthermore, a support ring is provided on the top outer wall of the support tube, and a thread is provided on the outer wall of the support tube above the support ring, which can be used to connect with the external pumping hose through a pipe joint; and the wiring of the vibration motor can be tied to the outer wall of the pumping hose with cable ties so that it extends outward to the power connection point, which can not only meet the power connection requirements, but also prevent the wiring from being scattered or tangled.

[0035] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
