Description

Technical Field

[0001] This utility model relates to the field of aggregate conveying technology, specifically to a belt conveyor for aggregate transportation. Background Technology

[0002] Belt conveyors, also known as belt conveyors or rubber belt conveyors, are indispensable and economical logistics transportation equipment for forming rhythmic assembly lines. Belt conveyors can be classified into heavy-duty belt conveyors and light-duty belt conveyors according to their conveying capacity. Belt conveyors feature high conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automated operation. Belt conveyors use the continuous or intermittent movement of a conveyor belt to transport materials or powdery or granular materials. They operate at high speed, smoothly, with low noise, and can convey materials uphill and downhill.

[0003] The existing reference is Chinese utility model patent CN215286649U, which discloses an aggregate belt conveyor device, relating to the technical field of belt conveyor devices, and solving the technical problem of easy material leakage in existing aggregate belt conveyor devices. The technical solution adopted is as follows: It includes a frame, on which multiple support rollers are rotatably mounted. A belt is wound around the multiple support rollers. Between each pair of adjacent support rollers supporting the upper belt, two sets of clamping mechanisms are provided corresponding to the two edges of the belt. The clamping mechanisms consist of two sets of symmetrical roller assemblies. Each roller assembly includes a mounting frame that can slide up and down on the frame. The upper and lower mounting frames are connected by a tension spring. A roller is rotatably mounted on the end face of the mounting frame opposite to the other mounting frame, and the rolling direction of the roller is consistent with that of the belt.

[0004] The existing conveyor belt structure bears the weight of the aggregate above, causing the belt to deform. The two sides of the belt move towards the center, resulting in deformation and keeping the belt in a taut state, which affects the service life of the belt. At the same time, the belt will run under deformation for a long time. After the belt is deformed, it cannot recover, resulting in curling on both sides of the belt. The belt and the drive roller cannot be tightly connected, resulting in a reduction in the contact area between the belt and the drive roller, which affects the transmission efficiency.

[0010] As a preferred embodiment of this utility model, the limiting shaft, the drive shaft, and the limiting frame are rotatably connected. The left end of the drive shaft passes through the left limiting frame and is located on the left side of the limiting frame. The toothed plate is symmetrically installed on the left and right sides of the limiting shaft and the drive shaft.

[0011] As a preferred embodiment of this utility model, the toothed disc is fixedly connected to the limiting shaft and the drive shaft, and the chain is symmetrically installed on the outer sides of the toothed discs on the left and right sides of the limiting shaft and the drive shaft; the chain can drive the belt to rotate.

[0012] As a preferred embodiment of this utility model, the connecting block is mirror-symmetrical about the center of the belt and is installed at equal distances on the left and right ends of the inner side of the belt; the connecting block facilitates the connection between the chain and the belt.

[0015] Compared with the prior art, the present invention provides a belt conveyor for aggregate transportation, which has the following advantages:

[0016] 1. This utility model, through the setting of the chain, has the toothed sprockets symmetrically installed on the left and right sides of the limiting shaft and the drive shaft. The toothed sprockets are fixedly connected to the limiting shaft and the drive shaft. The chain is symmetrically installed on the outer side of the toothed sprockets on the left and right sides of the limiting shaft and the drive shaft. The left end of the drive shaft is fixedly connected to the rotating shaft of the drive motor by an insertion method. The drive motor can drive the drive shaft to rotate.

This method can avoid the deformation of the outer edge of the belt from affecting the transmission efficiency.

[0017] 2. This utility model, through the setting of spring, causes the center of the belt to sink downward after the belt bears the load, causing the centrally fixed connecting frame to move downward. At the same time, the position of the connecting block is restricted by the chain, causing the connecting frame to pull the spring downward. The reaction force generated by the spring after the belt bears the load restricts the position of the belt center, preventing the belt from deforming too much. After the rubber wheel contacts the slide groove, it will transmit the force to the slide groove to support the belt center, thereby limiting the degree of belt deformation after the belt bears the load.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a belt conveyor for transporting aggregates includes: a limiting frame 1, a support frame 11 fixedly installed on one side of the limiting frame 1, a slide groove 12 fixedly installed on the upper part of the support frame 11, a limiting shaft 13 inserted at the rear end of the limiting frame 1, a drive shaft 14 inserted at the front end of the limiting frame 1, a toothed disc 15 fixedly installed on both sides of the limiting shaft 13 and the drive shaft 14, a chain 16 meshing with the outer side of the toothed disc 15, a drive motor 17 fixedly installed on the left end of the drive shaft 14, a connecting rod 18 fixedly installed on one side of the connecting shaft of the chain 16, a connecting block 19 fixedly installed on the outer side of the connecting rod 18, a belt 110 fixedly installed on the upper part of the connecting block 19, a connecting frame 111 fixedly installed at the center of the belt 110, a rubber wheel 112 movably installed at the bottom end of the connecting frame 111, and a spring 113 suspended between the connecting frame 111 and the connecting block 19.

[0027] The limiting frame 1 is mirror-symmetrically mounted on the left and right sides of the limiting shaft 13 with the center of the limiting shaft 13 as the reference. The support frame 11 is equidistantly mounted between the limiting frames 1. The limiting shaft 13, the drive shaft 14 and the limiting frame 1 are rotatably connected. The left end of the drive shaft 14 passes through the left limiting frame 1 and is located on the left side of the limiting frame 1. The chain 15 is symmetrically mounted on the left and right sides of the limiting shaft 13 and the drive shaft 14. The chain 15 is fixedly connected to the limiting shaft 13 and the drive shaft 14. The chain 16 is symmetrically mounted on the left and right sides of the limiting shaft 13 and the drive shaft 14. On the outer sides of the left and right sides of the toothed sprockets 15 on the shaft 14, the connecting blocks 19 are mirror-symmetrical with respect to the center of the belt 110 and are equidistantly installed at the left and right ends of the inner side of the belt 110. The belt 110 is fixedly connected to the chain 16 through the connecting blocks 19 and the connecting rod 18. The connecting frame 111 is equidistantly installed at the front and back on the inner side of the belt 110. The connecting frame 111 is located at the center of the belt 110 and between the left and right connecting blocks 19. The spring 113 is movably connected to the connecting blocks 19 and the connecting frame 111 through the ring structure at both ends.

[0028] Specifically, the limiting frame 1 restricts the position between the limiting shaft 13 and the drive shaft 14. The support frame 11 is installed equidistantly between the limiting frames 1, so that when the slide groove 12 is subjected to downward pressure, the force is transmitted to the limiting frame 1. The slide groove 12 can support the rubber wheel 112. The limiting shaft 13 can restrict the position of the rear end of the chain 16 through the outer toothed sprocket 15. The toothed sprocket 15 on the outer side of the drive shaft 14 can drive the chain 16 to rotate when the drive shaft 14 rotates. The left end of the drive shaft 14 is fixedly connected to the shaft of the drive motor 17 through an insertion method. The drive motor 17 can drive the drive shaft 14 to rotate. The connecting rod 18 is fixedly connected to the pin of the chain 16 so that when the chain 16 rotates... When in motion, the connecting block 19 rotates, which in turn drives the belt 110 to rotate. The left and right sides of the connecting frame 111 are connected to the connecting blocks 19 on the left and right sides via springs 113. When the belt 110 bears the weight, the center will be recessed downward, causing the centrally fixed connecting frame 111 to move downward. At the same time, the position of the connecting block 19 is restricted by the chain 16, causing the connecting frame 111 to pull the spring 113 downward. The reaction force generated by the spring 113 after the belt 110 bears the weight restricts the position of the center of the belt 110, preventing the belt 110 from undergoing excessive deformation. After the rubber wheel 112 contacts the slide groove 12, the force will be transmitted to the slide groove 12 to support the center of the belt 110.

[0029] In use, the chainrings 15 are symmetrically mounted on the left and right sides of the limiting shaft 13 and the drive shaft 14. The chainrings 15 are fixedly connected to the limiting shaft 13 and the drive shaft 14. The chain 16 is symmetrically mounted on the outer side of the chainrings 15 on the left and right sides of the limiting shaft 13 and the drive shaft 14. The left end of the drive shaft 14 is fixedly connected to the shaft of the drive motor 17 by a through-hole method. The drive motor 17 can drive the drive shaft 14 to rotate. The connecting rod 18 is fixedly connected to the pin of the chain 16 so that when the chain 16 rotates, it drives the connecting block 19 to rotate. The connecting block 19 can drive the belt 110 to rotate. This method can avoid belt... The deformation of the outer edge of belt 110 affects the transmission efficiency. When belt 110 is under load, the center will be concave downward, causing the centrally fixed connecting frame 111 to move downward. At the same time, the position of connecting block 19 is restricted by chain 16, causing connecting frame 111 to pull spring 113 downward. The reaction force generated by spring 113 after belt 110 is under load restricts the position of the center of belt 110, preventing excessive deformation of belt 110. After rubber wheel 112 contacts slide groove 12, the force will be transmitted to slide groove 12 to support the center of belt 110, thereby limiting the degree of deformation of belt 110 after belt 110 is under load.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
