Example (b):

referring to fig. 1 to 6, an embodiment of the present invention discloses a water-cooled scraper conveyor, which includes a frame 100, a conveying structure 200, a supporting wheel 300, a tensioning assembly 400, and a water-cooling device (not shown).

The water-cooling scraper conveying device disclosed by the invention can tension the chain 230 by utilizing the tensioning device, so that the chain 230 running for a long time is prevented from loosening. The supporting wheels 300 are arranged in a plurality of manners, the supporting wheels 300 support the chain 230, the upper half portion of the chain 230 can be flat, the force required for tensioning the chain 230 is reduced, on one hand, the scraper 240 can be guaranteed to be in close contact with a material supporting plane, on the other hand, the pulling force borne by the chain 230 can be reduced, and therefore abrasion to the chain 230 is reduced.

The conveying structure 200 includes a driving wheel 210, a driven wheel 220, a chain 230 and a scraper 240, wherein the chain 230 is wound between the driving wheel 210 and the driven wheel 220, and the scraper 240 is mounted on the chain 230. The two chains 230 are respectively installed at two ends of the driving wheel 210 and the driven wheel 220, and two ends of the scraping plate 240 are respectively connected with the two chains 230. The top of the frame 100 has a support plane for the material between the two chains 230, with which the bottom of the scraper 240 is in contact. The bottom of the rack 100 is provided with a first hole and a second hole, the first hole and the second hole are communicated with each other, the first hole is a threaded hole, and the cross section of the second hole is rectangular.

The water cooling device is sequentially coated on the outer wall of the middle rack 100, a U-shaped water clamping layer is formed between the water cooling device and the middle rack 100, the water cooling device comprises a shell forming the U-shaped water clamping layer with the middle rack 100, and a water inlet, a water outlet and an exhaust hole which are arranged on the shell, and the water inlet and the water outlet are respectively connected to an external water inlet pipeline and an external water outlet pipeline.

Referring to fig. 5, the tension assembly 400 includes an adjustment plate 410, a tension wheel 420, a slider 430, a connecting rod 440, and an adjustment rod 450. The adjusting plate 410 is rotatably connected with the frame 100, and the adjusting plate 410 is connected with the frame 100 through a one-way bearing. The tension pulley 420 is rotatably coupled to a first end of the adjustment plate 410, and the tension pulley 420 is engaged with the chain 230. When the adjusting plate 410 is rotated in the first direction, the tensioning wheel 420 can tension the chain 230, and the one-way bearing is arranged such that the adjusting plate 410 can freely rotate in the first direction, but when the adjusting plate 410 is locked in the second direction, i.e., the adjusting plate 410 cannot rotate in the second direction.

In the present embodiment, referring to fig. 1, the clockwise direction in fig. 1 is taken as the first direction, and the counterclockwise direction in fig. 1 is taken as the second direction.

The adjusting rod 450 is installed in the first hole, and the sliding block 430 is clamped in the second hole. The adjusting rod 450 is connected with the frame 100 by screw threads, the sliding block 430 is abutted against one end of the adjusting rod 450 facing the adjusting plate 410, and the sliding block 430 is connected with the frame 100 in a sliding manner. A first end of the connecting rod 440 is rotatably connected to the slider 430, and a second end of the connecting rod 440 is rotatably connected to a second end of the adjusting plate 410. When the adjusting rod 450 is screwed, the adjusting rod 450 can push the sliding block 430 to move towards the adjusting plate 410, at this time, the sliding block 430 pushes the connecting rod 440 to rotate, and further, the adjusting plate 410 is driven to rotate along the first direction, at this time, the tensioning wheel 420 sinks, and the tensioning action is completed. When the adjusting lever 450 is loosened, the thrust force applied to the tensioning wheel 420 and the adjusting plate 410 by the tensioned chain 230 by the one-way bearing also cannot rotate the adjusting plate 410 in the second direction, thereby providing a stable tensioning effect on the chain 230.

The water-cooling scraper conveying device disclosed in the embodiment further comprises a blowing component 500 for cleaning the scraper 240, so that a large amount of materials can be prevented from being attached to the scraper 240, and the conveying efficiency of the scraper 240 is improved. The blower assembly 500 includes a support structure 510 and a blower 520.

Wherein the support structure 510 includes a first support bar 511, a second support bar 512, a mounting plate 513, and a connecting bar 514. One end of the connecting bar 514 is connected with the sliding block 430, and the other end of the connecting bar 514 is connected with the second supporting bar 512. A first end of the second support rod 512 is connected to the connecting bar 514, and a second end of the second support rod 512 is rotatably connected to a second end of the mounting plate 513. A first end of the first support bar 511 is rotatably coupled to the connection bar 440, and a second end of the first support bar 511 is rotatably coupled to a first end of the mounting plate 513.

The first support bar 511, the second support bar 512, the mounting plate 513 and the connecting bar 440 form a parallelogram mechanism, and the second support bar 512 is connected with the sliding block 430 through the connecting bar 514, that is, in the process that the second support bar 512 moves along with the sliding block 430, the second support bar 512 does not rotate, so that the second support bar 512 and the first support bar 511 can be ensured to always keep an initial angle, in the embodiment, the first support bar 511 and the second support bar 512 can be always kept in a horizontal state, and thus the mounting plate 513 is closer to the chain 230, and the blower 520 can work conveniently.

Further, the mounting plate 513 and the connecting rod 440 are respectively located on both sides of the tension wheel 420.

Specifically, referring to fig. 1, in the operation process, when the chain 230 needs to be tensioned further, the adjusting rod 450 is screwed, the adjusting rod 450 drives the sliding block 430 to move upwards, the sliding block 430 drives the connecting rod 440 and the adjusting plate 410 to rotate, the connecting rod 440 rotates in the second direction, the adjusting plate 410 rotates in the first direction, and the tensioning wheel 420 is driven to press downwards, so that the chain 230 is tensioned. Meanwhile, when the connecting rod 440 rotates in the second direction, the mounting plate 513 in the supporting structure 510 also rotates in the second direction, and the plate of the mounting plate 513 is always parallel to the connecting rod 440. The lower half of the chain 230 may be divided into a first strand 231 and a second strand 232, with the first strand 231 located to the right of the tensioner 420 and the second strand 232 located to the left of the tensioner 420 as shown in figure 1. Referring to fig. 2, when the idler 420 is pressed down, the chain 230 sinks at the position of the idler 420, and the first segment 231 and the second segment 232 can be regarded as rotating relative to the driven pulley 220 and the driving pulley 210, respectively, i.e. the first segment 231 rotates in the second direction and the second segment 232 rotates in the first direction.

Therefore, when the tensioner 420 is pressed down, the mounting plate 513 and the first segment 231 are both rotated in the second direction, and the relative angle between the mounting plate 513 and the first segment 231 is hardly changed or the angle between the mounting plate 513 and the first segment 231 is minimally changed. When the wind of blowing in of air-blower 520 blows along different angles, the cleaning efficiency to scraper blade 240 is different, consequently, can be according to the experimental result, make mounting panel 513 be the best contained angle with first section 231 at the beginning, when take-up pulley 420 moved down this moment, too big change can not take place for the angle between mounting panel 513 and the first section 231 yet to guarantee to remain throughout on the best contained angle between air-blower 520 and the first section 231, and then guarantee that the cleaning efficiency of scraper blade 240 can receive the influence of tensioning assembly 400.

In this embodiment, the connection bar 514 may be provided in a hollow structure, that is, a through hole 5141 is provided on the connection bar 514, and the rotation shaft between the slider 430 and the connection rod 440 is located in the through hole 5141. Of course, the provision of the through hole 5141 on the connecting bar 514 is only one embodiment of the present embodiment, and in other embodiments, the connecting bar 514 may be provided in a column structure parallel to the rotation axis between the slider 430 and the connecting rod 440.

As a preferred embodiment of the present embodiment, the length of the connecting rod 440 is smaller than that of the adjusting plate 410. Thus, when the adjusting lever 450 is screwed, the slider 430 slides a small distance, and then the tension pulley 420 is lowered a sufficient distance to tension the chain 230.

Further, the rotation axis of the adjusting plate 410 is located below the chain 230, and the distance of the tension pulley 420 from the rotation axis of the adjusting plate 410 is greater than the distance of the connecting rod 440 from the rotation axis of the adjusting plate 410. This further increases the distance that the tensioning wheel 420 descends while the sliding blocks 430 slide the same distance, thereby reducing the change in the angle of the connecting rod 440, which in turn enables a smaller change in the relative angle between the mounting plate 513 and the first strand 231 of the chain 230.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
