Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a bending conveyor. Background Art

[0002] The conveyor is in two different states when it is in operation and when it is moving. It is unfolded to achieve conveying when it is in operation, and needs to be bent or folded when it is moving to reduce space occupation. The patent CN 116654558 A previously applied by the applicant discloses a multi-section retractable conveyor belt device, which can be converted into two states of unfolding or folding, so that it can be folded to the side at a certain angle when moving to reduce space occupation.

[0003] However, in the multi-section retractable conveyor belt device disclosed in CN 116654558 A, the folded belt support assembly is in a form with the side facing outward. Since the belt support assembly has a certain width, it still occupies a large space on the side of the brushing machine, that is, the space occupied after folding is still large. Utility Model Content

[0004] In view of the above shortcomings, the utility model provides a bending conveyor, which can solve the problem that the existing bending conveyor occupies a large space after bending.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A bending conveyor includes a front-end belt support assembly and a terminal belt support assembly, and also includes a middle flipping member, wherein the rear end of the middle flipping member is rotatably connected to the front end of the terminal belt support assembly so that the middle flipping member can flip up and down around the rotation connection point, the rear end of the front-end belt support assembly is rotatably connected to the front end of the middle flipping member so that the front-end belt support assembly can rotate around the rotation connection point on a horizontal plane where the two are located, a first driving member for driving the two to rotate relative to each other is arranged between the front-end belt support assembly and the middle flipping member, and a second driving member for driving the two to rotate relative to each other is arranged between the terminal belt support assembly and the middle flipping member.

[0007] Furthermore, the middle flip member includes an end connection part and a front connection part, the end connection part is rotatably connected to the end belt support assembly, the front connection part is rotatably connected to the front belt support assembly, and the front connection part is located in the middle in front of the end connection part, and the first driving member is a telescopic cylinder, and the front end of the first driving member of the telescopic cylinder is rotatably connected to the middle part of the front belt support assembly, and the end is rotatably connected to the end connection part.

[0008] Furthermore, the terminal connection part and the front connection part form a structure that is smaller in the front and larger in the back, so that the end of the first driving member of the telescopic cylinder is rotatably connected to the side edge of the terminal connection part.

[0009] Furthermore, a limiting rod is fixedly arranged on the other side of the middle flip member relative to the side where the first driving member is arranged, and a limiting groove is arranged at the rear end of the front end belt support assembly so that when the front end belt support assembly is rotated to be consistent with the longitudinal extension direction of the middle flip member, the limiting rod matches and snaps into the limiting groove.

[0010] Furthermore, the second driving member is a telescopic cylinder, and the front end of the second driving member of the telescopic cylinder is rotatably connected to the middle flip member, and the end is rotatably connected to the end belt support assembly.

[0011] Furthermore, a first mounting seat is fixedly provided on the side edge of the middle flip member, and a second mounting seat is fixedly provided on the side edge of the end belt support assembly, and the front end of the second driving member of the telescopic cylinder is rotatably connected to the first mounting seat, and the end is rotatably connected to the second mounting seat.

[0012] Furthermore, the second mounting seat is located below the bottom of the side edge of the end belt support assembly so that the second driving member is tilted forward and upward.

[0013] Furthermore, the top of the rear end of the middle flip member is rotatably connected to the top of the front end of the end belt support assembly, and when the middle flip member is rotated to be on the same horizontal plane as the end belt support assembly, the rear end of the middle flip member abuts against the front end of the end belt support assembly so that the middle flip member cannot continue to flip downward.

[0014] Furthermore, the two sides of the top of the rear end of the middle flip member are rotatably connected to the two sides of the top of the front end of the end belt support assembly, and the front end of the end belt support assembly is fixedly provided with an abutment block for abutting the rear end of the middle flip member.

[0015] Furthermore, there are two second driving members, which are respectively arranged on both sides of the end belt supporting assembly and the middle flip member.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: in the bending conveyor of the utility model, after the front end belt support assembly is bent to the side to a certain angle, the middle flip member is flipped upward, and the front end belt support assembly connected to the second driving member is flipped together. The front end belt support assembly changes from a form with one side facing outward to a form with one side facing upward (or downward), and the distance it extends outward is small, so that the space occupied on the side of the brushing machine after bending is relatively small. The space occupied after bending is relatively small, which helps to reduce space occupation and facilitates movement. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please refer to Figures 1 to 5 The preferred embodiment of the utility model provides a bending conveyor, including a front-end belt support assembly 10 and a terminal belt support assembly 20, and a middle flip member 30 located between the front-end belt support assembly 10 and the terminal belt support assembly 20, the rear end of the middle flip member 30 is rotatably connected to the front end of the terminal belt support assembly 20 so that the middle flip member 30 can flip up and down around the rotation connection point, the rear end of the front-end belt support assembly 10 is rotatably connected to the front end of the middle flip member 30 so that the front-end belt support assembly 10 can rotate around the rotation connection point on the horizontal plane where the two are located to achieve side bending, a first driving member 40 for driving the two to rotate relative to each other is arranged between the front-end belt support assembly 10 and the middle flip member 30, and a second driving member 50 for driving the two to rotate relative to each other is arranged between the terminal belt support assembly 20 and the middle flip member 30.

[0028] In a preferred exemplary embodiment, the middle flip member 30 and the end belt support assembly 20 are flipped up and down around the rotation connection point so that the end belt support assembly 20 and the middle flip member 30 are on the same horizontal plane, and can be driven by the second drive member 50 to make the middle flip member 30 rotate upward at a certain angle, such as 90°, around the front end of the rotation connection point, or after being flipped upward at a certain angle, under the drive of the second drive member 50, the middle flip member 30 rotates downward at a certain angle around the front end of the rotation connection point so that the end belt support assembly 20 and the middle flip member 30 can be on the same horizontal plane. At this time, the front and rear end extension directions of the end belt support assembly 20 and the middle flip member 30 are consistent.

[0029] During implementation, in an exemplary implementation, when the conveyor operation is required, the second driving member 50 drives the end belt support assembly 20 and the middle flip member 30 to be on the same horizontal plane. At this time, the front and rear end extension directions of the end belt support assembly 20 and the middle flip member 30 are consistent, and the first driving member 40 drives the front belt support assembly 10 and the front and rear end extension directions of the middle flip member 30 to be consistent. At this time, the bending conveyor is in an unfolded state to realize the conveying operation (please refer to Figures 1 to 3 ), and when it is necessary to move, the space occupied by the bending conveyor needs to be minimized. First, the front belt support assembly 10 is driven by the first driving member 40 to rotate around the rotating connection point on the horizontal plane where the two are located to achieve side bending. After bending to a certain angle, the middle flip member 30 is flipped upward by the second driving member 50. At this time, the front belt support assembly 10 connected to the second driving member 50 is flipped together, and the front belt support assembly 10 changes from a side-outward form to a side-up (or downward) form (please refer to Figure 4 and Figure 5 ), since the thickness of the front belt support assembly 10 is significantly smaller than the width, after being turned over and formed into a form with the side facing up (or down), the distance it extends outward is small, so that the space occupied on the side of the brushing machine after bending is relatively small, that is, the space occupied after bending is relatively small. By using the bending conveyor of the utility model, the bending conveyor occupies a relatively small space after folding. At this time, the overall width of the brushing machine is small, which helps to reduce space occupation and facilitates movement. When the whole machine is transported, it will not be over-wide or over-high, and the space occupied is smaller. There is no need to fold down the conveyor when transporting the equipment, which saves the trouble of disassembly and assembly, saving time and effort.

[0030] In this preferred embodiment, the front belt support assembly 10 and the end belt support assembly 20 can be selected from the front belt support assembly and the end belt support assembly of the prior art. In an exemplary embodiment, the front belt support assembly 10 mainly includes a front belt support rod 12 and a front belt drive assembly, the front belt support rod 12 is a long rod-shaped structure, and a plurality of first belt supports 13 are installed on the front belt support rod 12 for supporting the conveyor belt. The first belt supports 13 are arranged at intervals on the front belt support rod 12 to ensure that the conveyor belt can work stably and reliably when conveying materials. The front belt drive assembly is fixedly connected to the end of the front belt support rod 12 (the end away from the middle flip member 30), wherein the front belt drive assembly is used to drive the movement of the conveyor belt installed on this device. The front belt drive assembly includes a front belt frame 16, a belt drive roller 14 and a belt driver 15. The front belt frame 16 is a frame structure and one end is connected to the front belt support rod 12. The belt drive roller 14 is rotatably connected to the end of the front belt frame 16 away from the front belt support rod 12. The belt driver 15 and the belt drive roller 14 are used to drive the rotation of the belt drive roller 14. The specific belt driver 15 can be driven by hydraulic pressure. The end belt support assembly 20 mainly includes an end belt frame 23. The end belt frame 23 is a frame structure and one end is connected to the middle flip member 30. A plurality of second belt supports 24 are installed on the end belt frame 23 to support the conveying belt. The second belt supports 24 are arranged at intervals on the end belt frame 23 to ensure that the conveying belt can work stably and reliably when conveying materials. A driven roller can also be arranged at the end of the end belt frame 23. When implemented, the conveying belt is sleeved on the first belt support 13 and the second belt support 24, and sleeved over the belt drive roller 14 and the driven roller, so as to realize conveying. When bending or folding is required, the conveyor belt can be removed without affecting the bending.

[0031] In a preferred embodiment, the middle flip member 30 includes a terminal connection portion 31 and a front connection portion 32, the terminal connection portion 31 is rotatably connected to the terminal belt support assembly 20, the front connection portion 32 is rotatably connected to the front belt support assembly 10, and the front connection portion 32 is located in the middle in front of the terminal connection portion 31, and the first driving member 40 is a telescopic cylinder, specifically a kind of oil cylinder, air cylinder, etc. The front end of the first driving member 40, which is a telescopic cylinder, is rotatably connected to the middle of the front belt support assembly 10, and the end is rotatably connected to the terminal connection portion 31. During implementation, when the first driving member 40, which is a telescopic cylinder, is extended, it can drive the front belt support assembly 10 to expand so that the front and rear ends of the front belt support assembly 10 and the middle flip member 30 extend in the same direction, and the first driving member 40, which is a telescopic cylinder, can be retracted so that the front belt support assembly 10 rotates around the rotation connection point on the horizontal plane where the two are located to achieve side bending.

[0032] Furthermore, the end connection part 31 and the front connection part 32 form a structure that is smaller in the front and larger in the back, and the end of the first driving member 40 of the telescopic cylinder is rotatably connected to the side edge of the end connection part 31. Through this structural form, the end of the first driving member 40 of the telescopic cylinder is at a certain distance from the rotation connection point between the front connection part 32 and the front belt support assembly 10 (regardless of the front-to-back direction or the left-to-right direction), so when the first driving member 40 of the telescopic cylinder is retracted, a larger angle of bending can be achieved, so that the angle formed by the front belt support assembly 10 and the middle flip member 30 after retraction and bending is less than 90°, and a larger bending storage can be achieved.

[0033] In a preferred embodiment, a limiting rod 33 is fixedly provided on the other side of the middle flip member 30 relative to the side where the first driving member 40 is provided, and a limiting groove 11 is provided at the rear end of the front belt support assembly 10, so that when the front belt support assembly 10 rotates to be consistent with the longitudinal extension direction of the middle flip member 30 (the front belt support assembly 10 and the front and rear end extension directions of the middle flip member 30 are consistent), the limiting rod 33 matches and snaps into the limiting groove 11, and at this time, the front belt support assembly 10 can no longer continue to rotate, so as to limit the front belt support assembly 10 and the middle flip member 30 to be consistent in the longitudinal extension direction. The limiting groove 11 is a notch structure opened toward the side, and the upper and lower parts of the limiting groove 11 can support the front belt support assembly 10, so as to keep the overall structure stable during operation.

[0034] Preferably, the second driving member 50 is a telescopic cylinder, specifically an oil cylinder, a gas cylinder, etc. The front end of the second driving member 50, which is a telescopic cylinder, is rotatably connected to the middle flip member 30, and the end is rotatably connected to the end belt support assembly 20. During implementation, when the second driving member 50, which is a telescopic cylinder, is extended, it can drive the middle flip member 30 to flip upward or downward so that the middle flip member 30 and the front belt support assembly 10 thereon are upward or downward. For example, when the front belt support assembly 10 is bent to a certain angle during folding and storage, the middle flip member 30 is flipped upward by the second driving member 50. At this time, the front belt support assembly 10 connected to the second driving member 50 is flipped together, and the front belt support assembly 10 changes from a side facing outward to a side facing upward (or downward).

[0035] In a preferred embodiment, the second driving member 50 can drive the middle flip member 30 to flip upward to be perpendicular to the end belt supporting assembly 20 .

[0036] It can be understood that during operation, that is, in the unfolded form, when the longitudinal extension direction of the front end belt support assembly 10 is consistent with that of the middle flip member 30, the middle flip member 30 can be driven to flip upward or downward by the second driving member 50, thereby adjusting the angle between the front end belt support assembly 10 and the ground or work surface during the conveying operation, and the adjustment only requires driving the front end belt support assembly 10 and the middle flip member 30, and the front end action point is on the middle flip member 30, so that the driving force required to drive the front end belt support assembly 10 and the middle flip member 30 to flip is smaller, and the state of being able to maintain a certain angle is more stable.

[0037] The side edge of the middle flip member 30 is fixedly provided with a first mounting seat 34, and the side edge of the end belt support assembly 20 is fixedly provided with a second mounting seat 21. The front end of the second driving member 50, which is a telescopic cylinder, is rotatably connected to the first mounting seat 34, and the end is rotatably connected to the second mounting seat 21. The second mounting seat 21 is located below the bottom of the side edge of the end belt support assembly 20 so that the second driving member 50 tilts forward and upward. The top of the rear end of the middle flip member 30 is rotatably connected to the top of the front end of the end belt support assembly 20, and when the middle flip member 30 rotates to the same horizontal plane as the end belt support assembly 20, the rear end of the middle flip member 30 abuts against the front end of the end belt support assembly 20 so that the middle flip member 30 cannot continue to flip downward, so that when the middle flip member 30 rotates to the same horizontal plane as the end belt support assembly 20, the driving force of the second driving member 50 is not required, and the rear end of the middle flip member 30 abuts against the front end of the end belt support assembly 20 to maintain the corresponding position. Furthermore, the two sides of the top of the rear end of the middle flip member 30 are rotatably connected to the two sides of the top of the front end of the end belt support assembly 20, and the front end of the end belt support assembly 20 is fixedly provided with an abutment block 22 for abutting the rear end of the middle flip member 30 to keep the end belt support assembly 20 and the middle flip member 30 on the same horizontal plane. There are two second driving members 50, which are respectively arranged on both sides of the end belt support assembly 20 and the middle flip member 30. The two second driving members 50 work simultaneously to ensure that the middle flip member 30 flips smoothly.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
