Description

Technical Field

[0001] The present invention relates to the technical field of tube chain conveyors, in particular to a retractable tube chain conveyor. Background Art

[0002] The tube chain conveyor is a continuous conveying equipment for conveying bulk materials such as powder, small particles and small blocks. In a closed pipeline, the chain is used as the transmission component to drive the material along the pipeline.

[0003] The existing pipe chain conveyor still has certain disadvantages during actual use. Since the chain rotates in a closed pipe, once the material is affected by the humid air in the room, the material will clump due to the increase in moisture. In severe cases, it will cause the pipe to be blocked. As the blockage worsens, the chain that is continuously under pressure will break due to the increase in pressure. At the same time, this prefabricated pipe cannot be freely expanded and contracted to the designated position for material transportation.

[0052] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0053] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0054] A retractable tube chain conveyor provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0055] Example 1:

[0056] Combine Figures 1-10As shown, the present invention provides a retractable tube chain conveyor, comprising a chain belt tensioning adjustment mechanism 100, two groups of telescopic feeding mechanisms 200 arranged in the chain belt tensioning adjustment mechanism 100, four groups of distance control mechanisms 300 arranged on the two groups of telescopic feeding mechanisms 200, a material body loosening mechanism 400 arranged in the chain belt tensioning adjustment mechanism 100, and a chain belt 500 arranged in the chain belt tensioning adjustment mechanism 100 and the two groups of telescopic feeding mechanisms 200. The chain belt tensioning adjustment mechanism 100 is used to cooperate with the two groups of telescopic feeding mechanisms 200 to provide a telescopic path for material transportation, the distance control mechanism 300 is used to provide distance adjustment kinetic energy to the telescopic feeding mechanism 200, the material body loosening mechanism 400 is used to provide a conveying platform for different materials and actively loosen the material, and the chain belt 500 is used to actively loosen the material.

[0057] The chain belt tensioning adjustment mechanism 100 includes two first machine covers 110, two second machine covers 120, two third machine covers 130 and multiple end posts 170. The two first machine covers 110, the two second machine covers 120 and the two third machine covers 130 are all provided with a stabilization linkage 180 and an anti-slip linkage 190;

[0058] The inner walls of the first hood 110 and the second hood 120 are both provided with two symmetrically distributed end posts 170;

[0059] The inner wall of the third hood 130 is provided with four symmetrically distributed end posts 170;

[0060] The first cover 110, the second cover 120 and the third cover 130 are all provided with slots inside, and two symmetrically distributed brush pieces 160 are installed in the slots;

[0061] The brush heads at the inner ends of two adjacent brush pieces 160 are symmetrical to each other, and the brush heads and the chain pieces in the chain belt 500 rotate in the same path;

[0062] The telescopic feeding mechanism 200 includes a second storage tube 220, two fourth storage tubes 280 disposed inside the second storage tube 220, a first storage tube 210 disposed at the outer end of one of the fourth storage tubes 280, and a third storage tube 230 disposed at the outer end of the other fourth storage tube 280;

[0063] The two fourth storage tubes 280 are both provided with a pressure-bearing linkage member 290; the distance control mechanism 300 is used to adjust the distance between the first storage tube 210 and the third storage tube 230;

[0064] The distance control mechanism 300 includes a screw 310, a nut 320 is provided on the threaded section of the screw 310, and a fourth spring 330 is provided on the outside of the screw 310;

[0065] A pressing plate 340 is provided on the threaded section of the screw rod 310 , and two symmetrically distributed support brackets 350 are movably mounted on both ends of the pressing plate 340 , and a spacer 360 is movably mounted on the other end of the support bracket 350 ;

[0066] The material loosening mechanism 400 is used to provide an effective conveying path for the material and actively loosen the material;

[0067] The chain belt 500 is connected to the stabilizing linkage 180, the anti-slip linkage 190 and the pressure-bearing linkage 290 for effectively transferring the materials in the path.

[0068] The port of the external material conveying pipeline is set just above the two vibrating plates 480. When the external material conveying pipeline pours the material toward the inside of the two vibrating plates 480, the running motor can drive the crankshaft 440 to rotate at high speed. At this time, the clamp 460 will drive the two inclined frames 470 to stretch at high frequency. Finally, the two vibrating plates 480 can vibrate at high frequency along the two slideways in the sealing plate 420. At this time, the material inside the two vibrating plates 480 can be actively loosened.

[0069] After the material is actively loosened, the loosened material will be transferred to the inner cavity of the two first machine covers 110. At this time, the chain belt 500 driven by the external driving device can transfer the loosened material to the third machine cover 130 and the second machine cover 120. Finally, the transferred material can be discharged to the designated location.

[0070] When it is necessary to freely adjust the material conveying path, multiple sets of distance control mechanisms 300 can be adjusted until the two sets of telescopic feeding mechanisms 200 are freely extended outward with the third machine cover 130 as the center. At this time, the lengths of the material input end and the discharge end can be freely controlled. In addition, the chain belt 500 passively brushed by multiple brushes 160 can be effectively cleaned during rotation. Finally, after the chain belt 500 is cleaned, it will not cause mixing to the subsequent types of materials.

[0071] The transferred material will not be affected by the indoor humidity and will not cause caking and clogging in the conveying channel.

[0072] Example 2:

[0073] Combine Figure 2-Figure 5 As shown, based on the first embodiment, the chain belt tensioning and adjusting mechanism 100 further includes six groups of traction components 140 and three pre-tensioning components 150;

[0074] The traction assembly 140 includes a base 141, a limit frame 142 arranged at the top of the base 141, a support rod 143 arranged inside the limit frame 142, a first spring 144 arranged outside the support rod 143, and a clamp 145 movably installed at the bottom end of the support rod 143.

[0075] Preferably, the limit frame 142 is fixed to the inner side of the base 141 by welding, and the top end of the first spring 144 is adapted to bear pressure on the bottom of the limit frame 142, and the bottom end of the first spring 144 is adapted to bear pressure on the anti-slip linkage 190.

[0076] The bottom of the chuck 145 is mounted on the anti-drop linkage 190;

[0077] The pre-tightening assembly 150 includes a support plate 154 mounted on the top of the support rod 143. A screw sleeve 153 is provided in the middle of the support plate 154. A screw rod 152 is provided inside the screw sleeve 153. A base 151 is movably mounted on the bottom end of the screw rod 152.

[0078] The anti-dropout linkage member 190 is composed of two rectangular pads, two shafts and two gears.

[0079] Preferably, the three bases 151 are respectively installed in the two first hoods 110, the two second hoods 120 and the two third hoods 130, and the end of the bottom of the pre-tightening assembly 150 is movably installed inside the base 151;

[0080] As the top wheel of the screw rod 152 rotates, the screw sleeve 153 and the support plate 154 will move up and down along the threaded section of the screw rod 152. At this time, the two support rods 143 installed at both ends of the support plate 154 will actively apply traction to the anti-slip linkage 190. At this time, the three raised parts of the chain belt 500 located in the two first machine covers 110, the two second machine covers 120 and the third machine cover 130 can be properly tensioned and regulated.

[0081] The chain belt 500 that is actively tensioned by the anti-slip linkage member 190 can cooperate with two adjacent brush pieces 160 to automatically clean the chain pieces.

[0082] Example 3:

[0083] Combine Figure 2 and Figure 9 As shown, based on the first embodiment, the telescopic feeding mechanism 200 further includes two first sheaths 240 and one second sheath 250;

[0084] One of the first sheaths 240 is mounted on the first storage tube 210 , the other first sheath 240 is mounted on the third storage tube 230 , and the second sheath 250 is mounted on the second storage tube 220 ;

[0085] The first sheath 240 and the second sheath 250 are both provided with a crossbar inside;

[0086] A second spring 260 is provided on the crossbar in the first sheath 240 , and two third springs 270 are provided on the crossbar in the second sheath 250 .

[0087] Preferably, the number of the first storage tube 210 and the third storage tube 230 is two, wherein one first storage tube 210 is installed at the inner end of the two first hoods 110, the other first storage tube 210 is installed at the inner end of the two second hoods 120, and the two third storage tubes 230 are installed at both ends of the two third hoods 130;

[0088] The tops of both ends of the fourth storage tube 280 are provided with raised slides, and two adjacent raised slides are movably mounted on the outside of the cross bar.

[0089] Example 4:

[0090] Combine Figure 2-Figure 8 As shown, in the above embodiment, the material loosening mechanism 400 includes a horizontal rail 410 provided in the two first machine covers 110, the two second machine covers 120 and the two third machine covers 130, a sealing plate 420 is provided at one end of the horizontal rail 410, a support leg 430 is installed at the outer end of the sealing plate 420, and a transmission assembly 450 is provided at the bottom of the horizontal rail 410;

[0091] A crankshaft 440 is movably mounted on the bottom of the support leg 430;

[0092] The transmission assembly 450 is composed of a chassis and a motor, and the other end of the crankshaft 440 is connected to the transmission shaft of the motor.

[0093] Preferably, the chassis is fixed to the bottom of the horizontal rail 410 by welding or bolts, and a heat dissipation slot is opened in the chassis. A wire is connected to the connector of the motor, and the wire is connected to the external power supply;

[0094] A bearing is provided in the slot at the bottom end of the support leg 430 , and an end of the crankshaft 440 away from the motor is installed in the bearing.

[0095] A clamp 460 is movably mounted on the crankshaft 440 . Two ends of the clamp 460 are connected to two oblique frames 470 . A vibration plate 480 is movably mounted on the top of each of the two oblique frames 470 .

[0096] Preferably, the two vibration plates 480 are attached to the bottom surface of the inner side of the horizontal rail 410 to form a U-shaped conveying trough. When the material is poured into the U-shaped conveying trough, the two vibration plates 480 under high-frequency vibration can actively loosen the material, and the loosened material will eventually be transferred to the inner cavity of the two first machine covers 110, and then be easily actively transferred by the chain belt 500.

[0097] The inner wall of the horizontal rail 410 is equipped with multiple sets of symmetrically distributed compression springs 490, and the other ends of the compression springs 490 are connected to the shock plate 480;

[0098] The shock plate 480 is composed of an L-shaped slider and an arc-shaped baffle, and the bottom end of the arc-shaped baffle is adapted to fit the bottom surface of the inner side of the horizontal rail 410, and the inner wall of the arc-shaped baffle is a smooth coating;

[0099] Two sliding grooves are provided inside the sealing plate 420 , and the L-shaped sliders are movably installed in the two sliding grooves of the sealing plate 420 .

[0100] Multiple groups of compression springs 490 arranged on the inner wall of the horizontal rail 410 are used to provide sufficiently stable elastic support force for the two vibration plates 480 to reset. With the high-frequency vibration of the two vibration plates 480, the multiple groups of compression springs 490 can not only improve the balance of the vibration amplitude, but also cooperate with the sealing plate 420 to gather the material in the center.

[0101] The working principle and use process of the present invention are as follows: an external material delivery pipe is pre-installed just above one end of the horizontal rail 410 close to the support leg 430, and the port of the material delivery pipe is installed in the middle of the two vibration plates 480;

[0102] As the external material delivery pipe pours the material into the gap between the two vibrating plates 480, the motor in the transmission assembly 450 is started, and the motor drives the crankshaft 440 to rotate at high speed, and the clamp 460 movably mounted on the outside of the crankshaft 440 drives the two inclined frames 470 to move up and down. At the same time, the two vibrating plates 480 loosen the material, and the loosened part of the material is transferred to the inside of the first hood 110.

[0103] As the material enters the inner cavity of the first hood 110, the chain belt 500 driven by the external driving force can effectively transfer the loose material along the inner side of the two vibrating plates 480. With the high-frequency vibration of the two vibrating plates 480, the actively transferred material can avoid agglomeration or adhesion. Finally, the material will pass through the third hood 130 and the second hood 120 in sequence and finally be transferred to the designated position.

[0104] In order to adjust the material conveying distance of the device, a wrench can be used to selectively adjust multiple nuts 320. As the nuts 320 effectively move laterally along the outside of the screw rod 310, the horizontally pushed pressure plate 340 will simultaneously apply a squeezing force to the two brackets 350. Finally, the two brackets 350 will push the two pads 360 to expand outward, and the first warehouse tube 210, the second warehouse tube 220 and the third warehouse tube 230 installed on the two sets of pads 360 will be effectively moved laterally outward under pressure until the first warehouse tube 210, the second warehouse tube 220 and the third warehouse tube 230 are extended outward at equal intervals along the two fourth warehouse tubes 280. Finally, the two sets of telescopic feeding mechanisms 200 can respectively push the first hood 110 and the second hood 120 to extend outward with the third hood 130 as the center.

[0105] As the two sets of telescopic feeding mechanisms 200 extend, the three screw rods 152 need to be rotated counterclockwise until the screw sleeve 153 and the support plate 154 fall downward along the screw rod 152. Finally, the two support rods 143 and the two clamps 145 installed in the support plate 154 will push the anti-slip linkage 190 to fall down until the chain belt 500 is relaxed accordingly with the extension of the two sets of telescopic feeding mechanisms 200.

[0106] The plurality of brushes 160 provided on the first hood 110, the second hood 120 and the third hood 130 and rising and falling accordingly with the chain belt 500 can also clean the pusher tray on the chain belt 500;

[0107] This device can freely adjust the extension length of the feeding end and the discharging end while avoiding the problem of adhesion caused by increased indoor humidity during material transportation. When conveying different materials, there will be no mixing of the materials due to residual materials on the surface of the chain belt 500.

[0108] 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 invention, and that the scope of the invention is defined by the claims and their equivalents.
