[0002] The function of the suction gun is to make the vacuum conveying system feed smoothly, and the ratio of the suction gun air intake to the material can be adjusted by adjusting the position of the suction gun suction tube in the outer tube and adjusting the opening of the air inlet, so as to conveniently control the material flow state.

[0003] The suction gun with adjustable air inlet still has certain defects in actual use. Since the suction gun needs to be set at the top of an open area to absorb the material, the suction gun is usually operated manually or mechanically. The material is affected by various factors, which will cause its internal adsorption force to increase, often causing the material sucked by the suction gun to be discontinuous or blocked.

[0009] In a preferred example, the present invention can be further configured as follows: the material suction mechanism further includes a delivery pipe installed at the top of the material gun, a ring gasket installed at the bottom of the material gun, and two elastic reset members installed on the ring gasket; The elastic reset element is composed of a main tube, a sub-rod and a sub-spring.

[0017] 2. The present invention arranges a heat-imparting protection mechanism outside the suction mechanism. When the heat-imparting protection mechanism continuously blows the heat flow toward the gun body, the gun body will eventually radiate heat energy toward its interior. As the airflow continuously transports the material upward, the radiated heat energy can dehumidify and dry the airflow, and at the same time dry the material, thereby preventing the material from forming lumps and adhering to the inner wall of the suction gun after being damp, thereby causing a contaminated area on the inner wall of the suction gun.

[0018] 3. In the present invention, the driving mechanism is arranged on the outer gun barrel. With the high-frequency impact of the support rod on the material gun, the frequency of the impact of the material gun and the frequency of its shaking due to the air pressure will eventually change. With the continuous input of the material, the material that has just entered the suction gun and is damp can be vibrated, and finally it will be quickly dried until it is powdered under the blowing of the dry high-temperature airflow.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A suction gun for a vacuum conveyor with adjustable air intake provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Embodiment 1: Combination Figures 1 to 10 As shown, the present invention provides a suction gun for an adjustable air intake vacuum conveyor, comprising a suction mechanism 100, a heat protection mechanism 200 arranged on the suction mechanism 100, a material loosening mechanism 300 arranged at the bottom of the suction mechanism 100, a stabilization component 400 arranged at the top of the suction mechanism 100, and a driving mechanism 500 arranged on the heat protection mechanism 200. The suction mechanism 100 is used to provide a conveying channel for the material, the heat protection mechanism 200 is used to provide heat radiation and protection for the suction mechanism 100, the material loosening mechanism 300 is used to actively loosen the material and suck it in evenly, the stabilization component 400 is used to provide shock absorption protection for the suction mechanism 100, and the driving mechanism 500 is used to knock and peel off the material in the suction mechanism 100.

[0025] The material suction mechanism 100 includes a material gun 110, a top plate 150 disposed on the top of the material gun 110, two first sliders 160 installed at the bottom of the top plate 150, a conveying pipe 120 installed at the top of the material gun 110, a ring washer 130 installed at the bottom of the material gun 110, and two elastic reset members 140 installed on the ring washer 130; The elastic reset member 140 is composed of a main tube, a sub-rod and a sub-spring; The top plate 150 is composed of an annular gasket and a vertical pipe, and a cushion layer is provided at the bottom of the annular gasket; The stabilizing assembly 400 includes a neck sleeve 420 disposed outside the two first sliders 160, a base 410 disposed at the bottom of the neck sleeve 420, transverse holes are opened on both sides of the base 410, and a limit terminal 430 is installed in the transverse hole, a guide rod 440 is movably installed inside the limit terminal 430, and a column head 450 is installed on the threaded section of the guide rod 440; The column head 450 is fixedly mounted on the outer wall of the material gun 110; A spring 460 is disposed outside the guide rod 440, and the inner end of the spring 460 bears pressure on the column head 450, and the outer end of the spring 460 bears pressure on the limit end head 430; The heat protection mechanism 200 includes an outer barrel 210 disposed at the bottom of the base 410, a sleeve 240 disposed on the outer barrel 210, and a heat flow input pipe 250 installed in the sleeve 240; The material loosening mechanism 300 includes a base 310 disposed at the bottom of the outer barrel 210 , a cushion 330 disposed at the bottom of the base 310 , and a bottom plate 340 disposed at the bottom of the cushion 330 ; The top of the bottom plate 340 is provided with a plurality of evenly distributed grooves, and an impeller 350 is disposed inside the groove.

[0026] When the conveying pipe 120 inhales air upward, the material gun 110 can introduce airflow through the gap between the cushion 330 and the bottom plate 340, and the introduced airflow will bring the material closer to the bottom plate 340. When the airflow pressure in the material gun 110 increases, the material gun 110 protected by the stabilizing component 400 can vibrate inside the outer barrel 210, and the vibrating bottom plate 340 can loosen the material around it. At the moment when the material is loosened, the airflow can guide the loosened material toward the groove on the top of the bottom plate 340, and along with the push of the impeller 350 by the airflow, the rotating impeller 350 can finally scrape the guided material into the inner cavity of the material gun 110; When the material is continuously transported upward along the inner cavity of the material gun 110, the material gun 110 in the exothermic state can dry the material passing through its inner cavity.

[0027] Embodiment 2: Combination Figures 3 to 6As shown, based on Example 1, the heat protection mechanism 200 further includes two bases 220 installed on the outer wall of the outer barrel 210 and two outer frames 230 installed outside the two bases 220; Two symmetrically distributed sheaths 260 are installed on the inner wall of the outer barrel 210, and the outer ends of the sub-springs are adapted to be clamped to the inside of the sheaths 260; The inner wall of the outer barrel 210 is provided with a heat insulation cushion layer and a moisture-proof layer, and the outer wall of the outer barrel 210 is coated with an anti-rust paint layer.

[0028] Preferably, a wire can be inserted into the heat flow input tube 250, and a heating coil can be wound around the outside of the material gun 110. When the coil is energized to release heat, the entire material gun 110 can be quickly heated up. According to the requirements of the heating efficiency of the material gun 110, the material of the material gun 110 can be selected according to actual needs; When the material gun 110 is located in the middle of the inner cavity of the outer barrel 210 to transport materials, the material gun 110 located in the middle of the inner cavity of the outer barrel 210 vibrates due to the airflow and can provide a vibration platform for the material during transportation to prevent the material from getting damp and agglomerating on the inner wall of the material gun 110.

[0029] Embodiment 3: Combination Fig.10 As shown, based on Example 1, the material loosening mechanism 300 further includes two second sliders 320 installed on the top of the cushion 330, and the second sliders 320 are movably installed in the slide groove at the bottom of the base 310; The bottom of the cushion 330 is provided with a transverse groove adapted to constrain the impeller 350; The impeller 350 is composed of a shaft, a shaft head and evenly distributed extended blades, and the shaft is installed in a hole inside the bottom plate 340 through a bearing.

[0030] Preferably, the base 310, the cushion 330 and the bottom plate 340 are all made of stainless steel, and the bottom plate 340 is fixed to the bottom of the cushion 330 by bolts or welding; When the airflow passes through the gap between the bottom plate 340 and the cushion 330 and drives the blades in the multiple impellers 350 to rotate, the materials accumulated around the bottom plate 340 can be scraped in, and the accumulated materials can be shaken and loosened with the high-frequency shaking of the bottom plate 340.

[0031] Embodiment 4: Combination Figures 3 to 9 As shown, in the above embodiment, the driving mechanism 500 includes a chassis 510 mounted on the outer wall of the outer barrel 210 and two clamps 570; A motor 520 is installed inside the chassis 510; A crankshaft 530 is movably mounted between the two clamps 570 , a clamping seat 540 is movably mounted on the crankshaft 530 , and a support rod 550 is movably mounted on the other end of the clamping seat 540 ; A horizontal sleeve 560 is mounted on the outer barrel 210, and the inner end of the support rod 550 is adapted to penetrate into the sleeve 560; A plug hole is provided at the top of the transmission shaft in the motor 520, and a plug rod is provided at the bottom of the crankshaft 530, and the plug rod is adapted to pass through the plug hole.

[0032] Preferably, the chassis 510 is fixedly mounted on the outer wall of the outer barrel 210 by bolts, and a lead slot is opened inside the chassis 510, and the wire is connected to the connector of the motor 520 through the lead slot. When the wire is energized, the motor 520 starts and the crankshaft 530 for assisting rotation will pull the clamp seat 540 and the support rod 550 to reciprocate and extend. Finally, the support rod 550 constrained by the sleeve 560 can apply a higher frequency impact force to the pad 170, thereby ensuring the appearance of dual-frequency shock waves in the material gun 110, and then the material passing through the inner cavity of the material gun 110 can be actively loosened.

[0033] The working principle and use process of the present invention: When the device is in use, as the material gun 110 and the conveying pipe 120 inhale air, the base 310, cushion 330 and bottom plate 340 arranged at the bottom of the material gun 110 can provide a passage for the input of materials. At this time, the high-pressure airflow will pass through multiple impellers 350, and the impellers 350 will rotate under pressure. At the same time, the material gun 110 is located in the middle of the inner cavity of the outer barrel 210 and remains centered. Under the continuous high pressure, the material gun 110 will vibrate, and the vibration force will radiate to the bottom plate 340.

[0034] With the high-frequency vibration of the bottom plate 340 in the material, the accumulated powder or granular material can be loosened before being sucked in, thereby avoiding stagnation or blockage during the suction of the material into the inner cavity of the material gun 110.

[0035] When the heat input pipe 250 inputs the drying heat into the gap between the material gun 110 and the outer gun barrel 210, the material gun 110 as a whole will continue to be heated until the heat is radiated to the airflow in the inner cavity of the material gun 110. The material that is carried upward along the inner cavity of the material gun 110 by the airflow can be evaporated accordingly, thereby avoiding the influence of the airflow and external moisture on the material input, and further avoiding the adhesion of agglomerated materials to the wall of the material gun 110.

[0036] At the same time, as the motor 520 starts, its internal transmission shaft will drive the crankshaft 530 to rotate, and the clamp seat 540 movably installed in the middle of the crankshaft 530 will pull the support rod 550 to stretch back and forth. Finally, the support rod 550 will knock on the pad 170 under the constraint of the sleeve 560. The vibration frequency of the knocking on the material gun 110 is higher than the vibration frequency brought to it by the wind pressure. Therefore, the material passes through the inner cavity of the material gun 110 and obtains abnormal wave back vibration, which can avoid the phenomenon of material caking and hanging on the wall, while ensuring the constant material conveying volume.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
