Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of idler groups, in particular to a heavy-duty idler group. Background Art:
[0002] The idler group is used to support the transmission belt and is mostly composed of an idler frame, an intermediate idler, a left idler, and a right idler. Although the existing traditional idler group can support and transmit the belt well, in some application scenarios with large impact forces, such as the idler group assembled at the material receiving position, when the material falls onto the belt and the idler group, it will generate a certain impact force on the belt and the idler group at this position. Using the existing traditional idler group, not only is the idler group prone to damage, but also the service life of the belt is greatly reduced. There is an urgent need for a heavy-duty idler group that can be well applied to the material receiving place. Summary of the Utility Model:
[0003] The purpose of the utility model is to provide a heavy-duty idler group for the deficiencies existing in the prior art, which can play a certain buffering role in the impact force of the falling material. Not only is the idler group not prone to damage, but it can also protect the belt and extend the service life of the belt, and can be better applied to application scenarios with large impact forces such as the material receiving place.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a heavy-duty idler group, including an idler frame, an intermediate idler, a left idler, and a right idler. The idler frame includes an installation base, a buffer bracket, and two shock absorbers. The two shock absorbers are respectively arranged on both sides of the installation base, and both ends of the buffer bracket are respectively arranged on the two shock absorbers. The intermediate idler, the left idler, and the right idler are respectively arranged on the buffer bracket. The intermediate idler, the left idler, and the right idler are respectively heavy-duty buffer idlers. The heavy-duty buffer idler includes an idler main body and a buffer rubber ring sleeved on the idler main body.
[0005] For further improvement of the above solution, the installation base includes two symmetrically arranged installation brackets. The two shock absorbers are respectively arranged at the bottoms of the two installation brackets. Buffer pads are respectively arranged at the tops of the two installation brackets, and the buffer pads are arranged at the upper left position of the left idler or the upper right position of the right idler.
[0006] For further improvement of the above solution, the buffer pad is made of polyurethane material.
[0007] For further improvement of the above solution, the buffer pad is detachably arranged on the installation bracket.
[0008] A further improvement to the above solution is that the two buffer pads are respectively inclined on the mounting bracket. The inclination angle of the buffer pad on the left is the same as that of the left idler, and the inclination angle of the buffer pad on the right is the same as that of the right idler.
[0009] A further improvement to the above solution is that the buffer rubber ring includes a plurality of annular protrusions and annular grooves, and the buffer rubber ring as a whole has a wavy structure.
[0010] The beneficial effects of the present utility model are as follows: A heavy-duty idler set provided by the present utility model includes an idler bracket, an intermediate idler, a left idler, and a right idler. The idler bracket includes a mounting base, a buffer bracket, and two shock absorbers. The two shock absorbers are respectively arranged on both sides of the mounting base, and both ends of the buffer bracket are respectively arranged on the two shock absorbers. The intermediate idler, the left idler, and the right idler are respectively arranged on the buffer bracket. The intermediate idler, the left idler, and the right idler are respectively heavy-duty buffer idlers. The heavy-duty buffer idler includes an idler main body and a buffer rubber ring sleeved on the idler main body.
[0011] When the present utility model is assembled at the material receiving position, when the material falls onto the belt and the present utility model, the shock absorbers on both sides of the mounting base can play a role in shock absorption and buffering for the buffer bracket, thereby greatly reducing the impact force on the intermediate idler, the left idler, the right idler, and the belt. Moreover, the buffer rubber rings on the intermediate idler, the left idler, and the right idler can further play a buffering role. The present utility model can play a certain buffering role in the impact force of the falling material. Not only is the idler set not easily damaged, but it can also protect the belt and extend the service life of the belt, and can be better applied to application scenarios with large impact forces such as material receiving locations. Description of the Drawings:
[0012] Figure 1 It is a structural schematic diagram of the present utility model.
[0013] Description of the reference numerals: Idler bracket 1, Mounting base 11, Mounting bracket 111, Buffer bracket 12, Shock absorber 13, Buffer pad 14, Intermediate idler 2, Idler main body 21, Buffer rubber ring 22, Annular protrusion 221, Annular groove 222, Left idler 3, Right idler 4. Detailed implementation manners:
[0014] The following further describes the present utility model in conjunction with the drawings, as Figure 1As shown in the figure, the utility model includes a roller frame 1, an intermediate roller 2, a left roller 3, and a right roller 4. The roller frame 1 includes a mounting base 11, a buffer bracket 12, and two shock absorbers 13. The two shock absorbers 13 are respectively arranged on both sides of the mounting base 11. The two ends of the buffer bracket 12 are respectively arranged on the shock absorbers 13. The intermediate roller 2, the left roller 3, and the right roller 4 are respectively arranged on the buffer bracket 12. The intermediate roller 2, the left roller 3, and the right roller 4 are respectively heavy-duty buffer rollers. The heavy-duty buffer roller includes a roller body 21 and a buffer rubber ring 22 sleeved on the roller body 21. When the utility model is assembled at the material receiving position, when the material drops onto the belt and the utility model, the shock absorbers 13 on both sides of the mounting base 11 can play a role in shock absorption and buffering for the buffer bracket 12, thereby greatly reducing the impact force on the intermediate roller 2, the left roller 3, the right roller 4, and the belt. The buffer rubber rings 22 on the intermediate roller 2, the left roller 3, and the right roller 4 can further play a buffering role. The utility model can play a certain buffering role in the impact force of the falling material, not only making the roller group not easily damaged, but also protecting the belt and prolonging the service life of the belt, and being better applicable to application scenarios with large impact forces such as material receiving places.
[0015] The mounting base 11 includes two symmetrically arranged mounting brackets 111. The two shock absorbers 13 are respectively arranged at the bottoms of the two mounting brackets 111. Buffer pads 14 are respectively arranged at the tops of the two mounting brackets 111. The buffer pads 14 are arranged at the upper left position of the left roller 3 or the upper right position of the right roller 4. When the belt runs off to one side due to the left-right imbalance of some falling materials and does not fall in the middle position, the buffer pads 14 respectively arranged at the upper left position of the left roller 3 and the upper right position of the right roller 4 can play a role in supporting and friction for the belt, thereby effectively protecting the belt.
[0016] The buffer pads 14 of the utility model are preferably made of polyurethane materials. The buffer pads 14 are arranged on the mounting brackets 111 in a detachable manner. When the buffer pads 14 are worn, the buffer pads 14 can be replaced, which is more practical.
[0017] The buffer pads 14 are respectively inclinedly arranged on the mounting brackets 111. The inclination angle of the buffer pad 14 on the left side is the same as the inclination angle of the left roller 3. When the belt runs off to the upper left of the left roller 3, the belt can more smoothly transition to the buffer pad 14 on the left side. The inclination angle of the buffer pad 14 on the right side is the same as the inclination angle of the right roller 4. When the belt runs off to the upper right of the right roller 4, the belt can more smoothly transition to the buffer pad 14 on the right side.
[0018] The buffer rubber ring 22 includes a plurality of annular protrusions 221 and annular grooves 222. The buffer rubber ring 22 as a whole has a wavy structure, which not only has good buffering performance, but also can well support and transmit the belt.
[0019] Working principle:
[0020] Assemble the present utility model at the material receiving position. When the material falls onto the belt and the present utility model, the shock absorbers 13 on both sides of the mounting base 11 can play a role in shock absorption and buffering for the buffer bracket 12, thereby greatly reducing the impact force on the intermediate idler 2, left idler 3, right idler 4 and the belt. The buffer rubber rings 22 on the intermediate idler 2, left idler 3 and right idler 4 can further play a buffering role; the present utility model can play a certain buffering role for the impact force of the falling material, not only the idler group is not easily damaged, but also can protect the belt and extend the service life of the belt, and can better be applied to application scenarios with large impact forces such as the material receiving place.
