Description

Technical Field

[0001] This utility model relates to a conveying device, and more particularly to a belt conveyor. Background Technology

[0002] A belt conveyor is a device that carries and transports materials via a conveyor belt running on a conveyor frame. A conventional belt conveyor has two conveyor pulleys, which are rotatably supported at both ends of the conveyor frame. The conveyor belt is fitted onto the two pulleys and driven by a conveyor motor through the pulleys. Therefore, such a belt conveyor is only used to transport materials in a straight line from the feed end to the discharge end of the conveyor. Its conveying distance is fixed. Once the feeding position is determined, the discharge position of the same belt conveyor can only be on a circle with the conveying length of the conveyor as the radius. When the required conveying discharge position does not correspond to the length of the conveyor, the belt conveyor cannot be used. Only by replacing it with a belt conveyor of the appropriate conveying length can the conveying be carried out. However, this is not easy to achieve, which makes belt conveyors very inconvenient in practical applications. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a foldable belt conveyor, which can conveniently change the conveying distance of the belt conveyor.

[0004] To solve the above-mentioned technical problems, this utility model provides a foldable conveyor belt, including a conveyor frame with several legs. The conveyor frame includes a front frame and a rear frame. A front conveyor belt runs on the front frame, and a rear conveyor belt runs on the rear frame. The output end of the front frame and the input end of the rear frame are connected by a material transfer device. The material transfer device includes a collecting hopper fixed to the front frame and a receiving hopper fixed to the rear frame. The upper opening of the collecting hopper corresponds to the output end of the front conveyor belt, and the lower opening of the collecting hopper is opposite to and inside the upper opening of the receiving hopper. The upper opening of the receiving hopper is circular, and the lower opening of the receiving hopper is above the input end of the rear conveyor belt.

[0005] After adopting the above technical solution, this belt conveyor is divided into a front conveying section consisting of a front frame and a front conveyor belt, and a rear conveying section consisting of a rear frame and a rear conveyor belt. The two sections are organically connected by a material transfer device. The material transfer device transfers the material output from the front conveying section through a hopper fixed to the front frame to a transfer hopper fixed to the rear frame, and then naturally falls onto the rear conveyor belt of the rear conveying section for continued conveying, ensuring continuous material conveying. In this way, the front and rear conveying sections can switch at the material transfer device instead of only maintaining a straight conveying direction. After switching, the conveying distance of this belt conveyor can be adjusted accordingly. The conveying distance changes with the turning angle α between the front and rear conveying sections. The maximum conveying distance is the distance when the front and rear conveying sections are in a straight line. As the turning angle α between the front and rear conveying sections increases, the conveying distance of the entire belt conveyor gradually shortens. This allows for relatively convenient changes to the conveying distance of the belt conveyor. The circular upper opening of the transfer hopper and the fact that the lower opening of the collection hopper is opposite to and within the upper opening of the transfer hopper ensure that the turning angle between the front and rear conveying sections is unrestricted, guaranteeing the continuity of material conveying, as long as there is no mechanical interference between the front and rear frames and their corresponding supports.

[0006] In a preferred embodiment of this invention, the circular upper opening of the transfer hopper is provided with a flange connection edge. The transfer hopper is circumferentially adjustable and fixedly connected to the collection hopper via this flange connection edge. With this embodiment, when the front frame and the rear frame are rotated, the flange connection edge at the circular upper opening of the transfer hopper and the collection hopper maintain a corresponding position, preventing misalignment between the transfer hopper and the collection hopper that would affect the transfer of materials.

[0007] In another preferred embodiment of this utility model, a frame turning and centering mechanism is provided at the input end of the rear frame. This mechanism includes a centering seat fixed to the rear frame, and a centering bracket matching the centering seat fixed to the ground. The rotation center determined by the frame turning and centering mechanism is located on the axis of the circular upper opening of the transfer hopper. With this embodiment, the rotation center position is determined by the frame turning and centering mechanism during the turning of the rear frame, thus ensuring a better positional relationship between the collecting hopper and the transfer hopper, preventing interference with material transfer, and facilitating the smooth turning process of the rear frame, making it easier to change the conveying distance of the belt conveyor.

[0008] In another preferred embodiment of this utility model, a frame turning and centering mechanism is provided at the input end of the front frame. This mechanism includes a centering seat fixedly connected to the front frame, and a centering bracket matching the centering seat fixedly connected to the ground. With this embodiment, the front frame can also be easily repositioned, making the installation of this belt conveyor more convenient.

[0009] In a further preferred embodiment of this invention, a concave spherical centering surface is provided on the centering seat, and a centering ball matching the concave spherical centering surface is provided at the top of the centering bracket. With this embodiment, the frame folding and centering mechanism is a spherical centering mechanism, allowing the front or rear frame to not only fold left and right around it, but also to fold up and down by a certain angle to change the height of the conveying outlet, thus broadening its application range.

[0010] In another preferred embodiment of this invention, the length of the centering bracket is adjustable along its axial direction. This embodiment allows for adaptation to different frame heights and enables the length to be reduced during conveyor relocation, facilitating changes in the conveyor's working position.

[0011] In another preferred embodiment of this invention, the lower opening of the transfer hopper is rectangular, and the length A of the rectangular lower opening of the transfer hopper is less than the width B of the subsequent conveyor belt. This embodiment ensures that the material falling from the transfer hopper is accurately positioned within the subsequent conveyor belt.

[0012] In a further preferred embodiment of this invention, the length of the support leg is adjustable along its axial direction. This embodiment allows the support leg to adapt to different terrain heights, ensuring the installation of the conveyor, and also meets the requirements for changing the conveying angle, thus having a wide range of applications.

[0013] In another further preferred embodiment of this invention, casters are installed at the lower end of the support legs, and these casters can rotate an angle around the vertical direction. With this embodiment, the belt conveyor can be easily pushed to the desired position, making installation and use convenient.

[0014] In another preferred embodiment of this utility model, the caster is a lockable swivel caster. With this embodiment, the swivel caster can automatically adapt to different walking directions, making it convenient to use. Its locking function allows it to be locked in place after installation, ensuring reliable operation. Attached Figure Description

Detailed Implementation

[0021] exist Figure 1 and Figure 2In the foldable belt conveyor shown, the conveyor frame includes a front frame 1 and a rear frame 9. Both the front frame 1 and the rear frame 9 are supported on the ground by several legs 4. The length of the legs 4 can be adjusted axially to ensure stable support and height adjustment of the conveyor frame. The installation angle of the front frame 1 and / or the rear frame 9 can also be changed by adjusting the length of each leg 4 to meet different output height requirements. The length adjustment structure of the legs 4 can adopt a common spiral connection structure of upper and lower sections. After adjustment, the adjusted length is locked with a set screw. For the conveyor to move into position, casters 5 are installed at the lower end of the support legs 4. These casters 5 can rotate around a vertical angle. The casters 5 are preferably lockable swivel casters. A front conveyor belt 3 runs on the front frame 1, and a rear conveyor belt 10 runs on the rear frame 9. The input end of the front conveyor belt 3 is the input end of the conveyor, and the output end of the rear conveyor belt 10 is the output end of the conveyor. The output end of the front frame 1 and the input end of the rear frame 9 are connected by a material adapter. This material adapter is fixed to the front frame 1 by side plates and corresponding support plates on both sides. The material collection hopper 6 and the transfer hopper 7 are fixed to the rear frame 9 via side plates and corresponding support plates on both sides. The upper opening of the material collection hopper 6 corresponds to the discharge position of the output end of the front conveyor belt 3. The lower opening of the material collection hopper 6 is opposite to and located inside the upper opening of the transfer hopper 7. The upper opening of the transfer hopper 7 is circular. A flange connecting edge 8 is provided around the circular upper opening of the transfer hopper 7. A connecting plate corresponding to the flange connecting edge 8 is provided on the material collection hopper 6. The connecting plate is connected to the flange connecting edge 8 by connecting bolts, and the connecting bolt holes on the flange connecting edge 8 are arc-shaped. The elongated hole, with its arc center located on the axis of the circular upper opening of the transfer hopper 7, allows the flange connecting edge 8 to change its circumferential position relative to the connecting plate on the collecting hopper 6 around the axis of the circular upper opening of the transfer hopper 7. Thus, the transfer hopper 7 can be adjusted and fixedly connected to the collecting hopper 6 via the flange connecting edge 8. Correspondingly, the rear frame 9 also rotates relative to the front frame 1, changing its left-right installation angle. After the rear frame 9 rotates relative to the front frame 1, the distance between the input and output ends of the conveyor becomes shorter than before the rotation, and the larger the rotation angle, the shorter the conveying distance. The lower opening of the transfer hopper 7 is located above the input end of the rear conveyor belt 10. The lower opening of the transfer hopper 7 is rectangular, and the length A of the rectangular lower opening of the transfer hopper 7 is less than the width B of the rear conveyor belt 9.

[0022] A frame turning and centering mechanism 2 is provided at the input end of the rear frame 9. The frame turning and centering mechanism 2 includes a centering seat 21 fixed to the rear frame 9 and a centering bracket 22 fixed to the ground. The centering bracket 22 can adopt a structure with upper and lower sections connected by a screw, so that the length of the centering bracket 22 can be adjusted along its axis. After adjustment, the adjusted length is locked by a set screw, which can adapt to the frame height requirements of different applications. At the same time, when the conveyor moves to a working position, the centering bracket 22 can retract to disengage from the ground to facilitate the relocation of the conveyor. The rotation center determined by the frame turning and centering mechanism 2 is located on the axis of the circular upper opening of the transfer hopper 7. In this way, when the rear frame 9 turns and adjusts relative to the front frame 1, the frame turning and centering mechanism 2 plays a turning and centering role, which not only facilitates the smooth progress of the turning process, but also ensures that the collection hopper and the transfer hopper maintain the corresponding positional relationship and does not affect the transfer of materials.

[0023] A frame turning and centering mechanism 2 can also be provided at the input end of the front frame 1 to facilitate the adjustment of the working position of the front frame 1. The frame turning and positioning mechanism 2 also includes a centering seat 21 and a centering bracket 22 that matches the centering seat 21. The centering seat 21 is fixedly connected to the front frame 1, and the centering bracket 22 is fixedly connected to the ground.

[0024] For a preferred embodiment, see Figure 4 A centering concave spherical surface 211 is provided on the centering seat 21, and a centering ball 221 matching the centering concave spherical surface 211 is provided at the top of the centering bracket 22. This allows the front frame 1 or the rear frame 9 to not only rotate left and right around it, but also to rotate up and down by a certain angle to change the height of the conveying outlet, thus expanding its application range.

[0025] The above are only some preferred embodiments of this utility model, but this utility model is not limited thereto, and many improvements and modifications can be made. Any improvements and modifications made based on the basic principles of this utility model should be considered to fall within the protection scope of this utility model.
