Technical Field

[0001] This utility model relates to the field of material conveying, and in particular to a conveyor with emergency stop buttons on both sides. Background Technology

[0002] In the grain transportation industry, belt conveyors are a commonly used piece of equipment. They transport grain from one place to another via a conveyor belt, offering advantages such as high efficiency and convenience. However, existing belt conveyors pose certain safety hazards during use. Traditional belt conveyors typically have supports on both sides of the conveyor belt to support it and ensure its normal operation. These supports have gaps, which, while facilitating installation and maintenance to some extent, present potential dangers to workers during actual operation. When workers are operating or maintaining the conveyor, their limbs or clothing can easily slip through the gaps in the supports and into the conveyor belt. If this happens, limbs may be scratched or abraded by the conveyor belt, and clothing may become entangled in it, leading to serious accidents. This not only threatens the personal safety of workers but may also damage the conveyor and disrupt the normal grain transportation process. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Please refer to Figure 1 and Figure 2The present invention relates to a conveyor with dual-sided emergency stop buttons, comprising a support frame 1 and a conveyor belt 2 mounted on the support frame 1, and a protective structure 3 mounted on the support frame 1. The protective structure 3 comprises several groups, which are arranged along the conveying direction of the conveyor belt 2 (i.e., the length direction of the support frame 1) to prevent workers' limbs or clothing from accidentally entering the area where the conveyor belt 2 is located. Simultaneously, the protective structure 3 also protects the conveyor belt 2 when the conveyor is not in use.

[0032] The support frame 1 includes a base frame 11 and an end frame 12 located on the upper end of the base frame 11. The base frame 11 is for contact with the ground, and its lower end is equipped with casters 13 to facilitate user movement of the conveyor. The end frame 12 is located on the upper end of the base frame 11 and is used to mount the conveyor belt 2. Please refer to... Figure 1 and Figure 8 Both sides of the bracket 1 are provided with emergency stop buttons 14 that are signal-connected to the conveyor belt 2 so as to control the conveyor belt 2 to stop.

[0033] Each set of protective structures 3 includes a first protective component 31 and a second protective component 32. The first protective component 31 and the second protective component 32 are symmetrically arranged on the lateral sides of the support 1. The first protective component 31 and the second protective component 32 can be engaged to cover the lateral sides of the support 1 and the upper end of the support 1, or they can be separated to not cover the upper end of the support 1 so that the conveyor belt 2 can be exposed.

[0034] Please refer to Figure 3 and Figure 4 The first protective component 31 includes a first fixing plate 311 for abutting against the side wall of the bracket 1 and a first movable plate 312 rotatably disposed on the upper end of the first fixing plate 311. The first fixing plate 311 is vertically disposed on the outer side of the corresponding side wall of the bracket 1, and the first fixing plate 311 is detachably connected to the bracket 1. Please continue to refer to Figure 5 and Figure 6Specifically, the outer wall of the bracket 1 is recessed with a first slot 313, which is formed along the length of the bracket 1. There are two first slots 313, located on the bracket 1 at the upper and lower parts corresponding to the first fixing plate 311, respectively. The first fixing plate 311 has a protruding first insert 314 at each of the two first slots 313, the first insert 314 matching the size of the first slot 313 to be inserted into it. The upper or lower wall of each of the two first slots 313 has a first limiting groove 315, which extends outward through the bracket 1 along the insertion direction of the first insert 314. There are multiple first limiting grooves 315, evenly spaced along the length of the corresponding first slot 313. Each of the first insert blocks 314 has a plurality of first limiting blocks 316 at positions corresponding to a plurality of first limiting grooves 315. The plurality of first limiting blocks 316 can be locked one-to-one into the plurality of first limiting grooves 315. The cooperation between the first limiting grooves 315 and the first limiting blocks 316 increases the contact surface between the first fixing block and the bracket 1, making the connection position of the first fixing block relative to the bracket 1 more accurate. Even if one contact surface is worn, the other contact surfaces can still cooperate with each other, providing a good limiting effect for the first fixing block. The increased contact surface also increases the friction between the first fixing block and the bracket 1, making the connection between them more stable. A first fixing hole 317 is provided between the bracket 1 and the first insert blocks 314 located at the top. The first fixing hole 317 has a plurality of holes evenly spaced along the length of the bracket 1. Each first fixing hole 317 has a first fixing bolt 318. The first fixing plate 311 is connected to the bracket 1 by cooperating with the first fixing hole 317 and the first fixing bolt 318. The first fixing hole 317 can be a screw hole, and the first fixing bolt 318 can be a bolt.

[0035] The first movable plate 312 is connected to the upper end of the first fixed plate 311 via a first connecting plate 319. One end of the first connecting plate 319 is hinged to the upper end of the first fixed plate 311 to allow rotation relative to the first fixed plate 311. In the illustrated embodiment, the rotation angle of the first connecting plate 319 is limited to 90 degrees to both sides, with the plane containing the first fixed plate 311 as the reference plane. The other end of the first connecting plate 319 is hinged to the first movable plate 312. When the first connecting plate 319 and the first movable plate 312 rotate away from the second protective component 32, the first connecting plate 319 can rotate to be parallel to the first fixed plate 311. Please refer to... Figure 2 When the first connecting plate 319 and the first moving plate 312 rotate toward the second protective component 32, the first connecting plate 319 and the first moving plate 312 are on the same horizontal plane and both the first connecting plate 319 and the first moving plate 312 are perpendicular to the first fixed plate 311. Please refer to... Figure 1 The first movable plate 312 has a first slot 3121 recessed from top to bottom at the end away from the first connecting plate 319. Figure 1 (The direction in the middle is for reference).

[0036] Please refer to Figure 7 , Figure 8 and Figure 9The second protective component 32 includes a second fixing plate 321 for abutting against the side wall of the bracket 1 and a second movable plate 322 rotatably disposed on the upper end of the second fixing plate 321. The second fixing plate 321 is vertically disposed on the outer side of the corresponding side wall of the bracket 1, and the second fixing plate 321 is detachably connected to the bracket 1. Specifically, the outer side wall of the bracket 1 is recessed with a second slot 323, which is opened along the length direction of the bracket 1. There are two second slots 323, and the two second slots 323 are respectively located on the bracket 1 at the upper and lower positions corresponding to the second fixing plate 321. The second fixing plate 321 is provided with a second insert 324 at each position corresponding to the two second slots 323, and the second insert 324 is sized to match the second slot 323 so as to be able to be inserted into the second slot 323. The upper or lower wall of each of the two second slots 323 is provided with a second limiting groove 325. The second limiting groove 325 extends outward through the bracket 1 along the insertion direction of the second insert 324, and there are several second limiting grooves 325, which are evenly spaced along the length direction of the corresponding second slot 323. Each second insert 324 is provided with several second limiting blocks 326 at positions corresponding to the several second limiting grooves 325, and the several second limiting blocks 326 can be locked into the several second limiting grooves 325 one by one. The cooperation effect of the second limiting block 326 and the second limiting groove 325 is the same as the cooperation effect of the first limiting block 316 and the first limiting groove 315 described above, so it will not be described in detail here. A second fixing hole 327 is provided between the bracket 1 and the second insert 324 located at the top. The second fixing hole 327 is provided with several evenly spaced along the length direction of the bracket 1. Each of the second fixing holes 327 has a second fixing bolt 328, which mates with the second fixing hole 327 to connect the second fixing plate 321 to the bracket 1. The second fixing hole 327 can be a screw hole, and the second fixing bolt 328 can be a bolt.

[0037] The second movable plate 322 is connected to the upper end of the second fixed plate 321 via a second connecting plate 329. One end of the second connecting plate 329 is hinged to the upper end of the second fixed plate 321 to allow rotation relative to the second fixed plate 321. In the illustrated embodiment, the rotation angle of the second connecting plate 329 is limited to 90 degrees to both sides, with the plane where the second fixed plate 321 is located as the reference plane. The other end of the second connecting plate 329 is hinged to the second movable plate 322. When the second connecting plate 329 and the second movable plate 322 rotate away from the first protective component 31, the second connecting plate 329 can rotate to be parallel to the second fixed plate 321; when the second connecting plate 329 and the second movable plate 322 rotate towards the first protective component 31, the second connecting plate 329 and the second movable plate 322 are located on the same horizontal plane and both the second connecting plate 329 and the second movable plate 322 are perpendicular to the second fixed plate 321. Please refer to the attached drawings. The second movable plate 322 is recessed from bottom to top at one end away from the second connecting plate 329. The second slot 3221 matches the first slot 3121. When the first movable plate 312 and the second movable plate 322 are engaged (that is, when the first movable plate 312 and the second movable plate 322 rotate towards each other until they are on the same horizontal plane), the first slot 3121 and the second slot 3221 engage with each other.

[0038] One embodiment of the conveyor with dual emergency stop buttons 14 of this utility model operates as follows: The material to be conveyed is placed on the conveyor belt 2, and the conveyor belt 2 transports the material to the target location. During this process, the first moving plate 312 retracts to be parallel to the first fixed plate 311, and the second moving plate 322 retracts to be parallel to the second fixed plate 321. The first fixed plates 311, on the one hand, limit the falling range of the material when it slides off the conveyor belt 2, preventing materials located at heights from falling and injuring workers; on the other hand, the arrangement of the first fixed plates 311 and the second fixed plates 321 also prevents workers' limbs and clothing from getting into the gaps between the supports 1 and becoming entangled in the conveyor belt 2.

[0039] If an emergency occurs during the operation of the conveyor and the operation of the conveyor belt 2 needs to be stopped, the operator can immediately stop the conveyor belt 2 by pressing the emergency stop button 14. Since there are two emergency stop buttons 14 symmetrically located on both sides of the support 1, the operator can react quickly to the emergency and stop the conveyor belt 2 in time, regardless of which side of the conveyor the operator is on, thus greatly increasing the safety of the conveyor operation.

[0040] When not in use, conveyors are usually covered with cloth to prevent excessive dust from entering and affecting their normal operation. However, while cloth primarily serves to cover, it lacks protective function. If a heavy object falls (such as a stone), the conveyor belt 2 can easily be damaged. In this case, the first movable plate 312 and the second movable plate 322 can provide protection for the conveyor belt 2. Specifically, the first movable plate 312 is first flipped over to be above the conveyor belt 2, and then the second movable plate 322 is flipped over to be above the conveyor belt 2, causing the first slot 3121 and the second slot 3221 to engage with each other. The engagement of the first slot 3121 and the second slot 3221 allows for a tighter fit between the first movable plate 312 and the second movable plate 322, providing better protection for the conveyor belt 2.

[0041] Compared with existing technologies, this utility model of a conveyor with dual-sided emergency stop buttons effectively solves the safety hazards of existing equipment by setting a protective structure on the belt conveyor support. The protective structure includes a fixed plate and a foldable movable plate. The fixed plate can cover the gaps on both sides of the support to prevent personnel's limbs or clothing from being caught, while also preventing materials from sliding and spilling, as well as dust pollution, thus improving the working environment. The movable plate can protect the conveyor belt from damage by debris when the conveyor is not in use. In addition, the protective mechanism adopts a detachable design, which facilitates maintenance and replacement, improving the safety and service life of the equipment while reducing maintenance costs. It meets industry safety standards and has significant practicality and innovation.
