DETAILED DESCRIPTION

[0018] For the purpose of facilitating the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The drawings show several embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. The terms "vertical", "horizontal", "left", "right", and the like as used herein are for purposes of illustration only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0021] As Figure 1 and Figure 2The first embodiment of the present invention is shown, which provides an adjustable elevation angle transmission device, including a front section component 1, a rear section component 2 rotatably connected to the front section component 1, and a transmission belt 3 disposed between the front section component 1 and the rear section component 2; the front section component includes a front section bracket 11, and a first pulley 12 rotatably connected to the front section bracket 11; the rear section component 2 includes a rear section bracket 21 rotatably connected to the front section bracket 11, and a second pulley 22 rotatably connected to the rear section bracket 21; the transmission belt 3 is disposed between the second pulley 22 and the first pulley 12; the transmission device further includes a roller 7 disposed on the front section bracket 11, the roller 7 contacting the lower inner side of the transmission belt 3, two mounting brackets 4 disposed on both sides of the front section bracket 11, and a roller assembly 5 detachably connected between the two mounting brackets 4 by a connecting component 6.

[0022] It is understandable that during the installation of the transmission device, if spatial obstacles are encountered, such as a flat front section but a step at the rear section, the rear section needs to be higher than the front section. This invention completely solves this technical problem, achieving a flexible layout. Specifically, when the rear section of the transmission device needs to be higher than the front section, the operator can rotate the rear support 21 during installation. This upward rotation of the rear support 21 drives the second pulley 22 upward, thus lifting the end of the rear support 21 away from the front support 11, causing the transmission belt 3 to present a "..." Figure 1 The "shape" of the transmission device allows the end section to be higher than the front section, creating an upward angle. This enables the device to function normally even in uneven working environments, achieving flexible layout. After adjusting the shape, the operator can connect the end bracket 21 to the solid body, and the front bracket 11 to the fixed body. The fixed body can be a wall, equipment, bracket 8, etc. In other words, the position of the beginning and end of the transmission device can be determined based on the working environment, and will be installed on a suitable solid body. Since the installation position of the beginning and end of the transmission device is existing technology, it will not be elaborated here. Furthermore, when the transmission device is adjusted to an upward angle, considering that the transmission belt 3 will bounce up and make it difficult to tightly engage with the first pulley 12 and the second pulley 22, thus preventing the effective raising of the angle of the transmission belt 3, a mounting frame 4, roller assembly 5, and roller shaft 7 are provided. This is understandable. Figure 2As shown, the roller shaft 7 contacts the lower inner side of the conveying belt 3 to press the conveying belt 3, and the roller assembly 5 contacts the upper surface of the conveying belt 3 on both sides to press the conveying belt 3, so that the corner part of the conveying belt 3 is at the same elevation angle as the front bracket 11. In addition, the elevation angle of the front bracket 11 is adjusted according to the working scene, and is not fixed. Therefore, the roller assembly 5 is vertically adjustable in height on the mounting frame 4, so that the roller assembly 5 is fully attached to the upper surface of the conveying belt 3. It can be understood that the operator dismounts the roller assembly 5 from the mounting frame 4 by operating the connecting assembly 6, and then adjusts the height as needed, places the roller assembly 5 at the corresponding height, and then fixes the roller assembly 5 through the connecting assembly 6.

[0023] The roller assembly 5 includes a mounting shaft 51, and two rotating wheels 52 rotatably connected on both sides of the mounting shaft 51. The two rotating wheels 52 respectively contact the upper surface of the conveying belt 3 on both sides.

[0024] The rotating wheel 52 contacts the upper surface of the conveying belt 3 on both sides, and the rotating wheel 52 is driven to rotate by the conveying belt 3 when the conveying belt 3 is conveying materials. The two ends of the mounting shaft 51 are respectively fixed on the two mounting frames 4 through the connecting assembly 6.

[0025] The connecting assembly 6 includes a plurality of through holes 61 opened in the vertical direction of the two mounting frames 4, two mounting plates 62 connected to the two mounting frames 4 through bolts 63 and nuts 64, and two ends of the mounting shaft 51 fixedly connected to the two mounting plates 62. One end of the bolt 63 is sequentially threaded through the mounting plate 62 and one of the through holes 61, and then the nut 64 is connected, so that the mounting plate 62 is fixedly connected to the mounting frame 4.

[0026] When it is needed to dismount the roller assembly 5 from the mounting frame 4, the operator first removes the nut 64 from the bolt 63, and then removes the bolt 63 from the through hole 61 and the mounting plate 62, so as to dismount the roller assembly 5 from the mounting frame 4. When it is needed to mount the roller assembly 5 to the mounting frame 4, the operator adjusts the height of the roller assembly 5 as needed, so as to place the roller assembly 5 at the corresponding through hole 61, and then the operator sequentially threads the bolt 63 through the mounting plate 62 and the through hole 61 at the position, and then connects the nut 64, so as to mount the roller assembly 5 to the mounting frame 4 at the appropriate height.

[0027] In summary, by rotating the last section bracket 21, the last section bracket 21 is rotated upwards, the second pulley 22 is moved upwards, the last section bracket 21 is lifted away from one end of the front section bracket 11, the last section of the conveying device is higher than the front section, and the conveying device can be used normally in uneven working environment, the layout is flexible, the corner part of the conveying belt 3 is at the same angle as the front section bracket 11 through the contact and pressing of the roller shaft 7 and the lower inner side of the conveying belt 3 and the contact and pressing of the roller assembly 5 on the upper surface of the conveying belt 3, and the conveying belt 3 with the adjusted angle can also stably convey materials; in addition, the roller assembly 5 can be fully attached to the upper surface of the conveying belt 3 with different angles through the vertical height adjustment of the roller assembly 5 on the mounting frame 4.

[0028] As Figure 3 and Figure 4 The second embodiment of the utility model, the difference between the first embodiment is that: the connecting assembly 6 includes a plurality of recessed holes 65 with openings which are opened on the two mounting frames 4 along the vertical direction, a plurality of limiting units 67 which are respectively arranged at the plurality of recessed holes 65, and two baffles 66 which are respectively arranged on the two sides of the mounting shaft 51, the mounting shaft 51 is located at the recessed hole 65, the two baffles 66 are respectively in contact with the outer sides of the two mounting frames 4, and the limiting unit 67 is used for preventing the mounting shaft 51 from being separated from the recessed hole 65.

[0029] It can be understood that when the roller assembly 5 needs to be disassembled from the mounting frame 4 when the connecting assembly 6 in the second embodiment is used, the operator can pull the corresponding limiting unit 67 to make the limiting unit 67 no longer limit the roller assembly 5, then the operator removes the roller assembly 5 from the opening of the recessed hole 65, that is, the disassembly of the roller assembly 5 is completed, when the roller assembly 5 needs to be installed on the mounting frame 4, first, the roller assembly 5 is correspondingly arranged in the appropriate recessed hole 65, then the two ends of the roller assembly 5 are respectively arranged in the recessed holes 65 of the two mounting frames 4 which are at the same horizontal level, when the roller assembly 5 is arranged, the roller assembly 5 will extrude the limiting unit 67, then the roller assembly 5 passes the extrusion unit, the extrusion unit resets to limit the roller assembly 5, which can prevent the roller assembly 5 from sliding out of the opening of the recessed hole 65, the baffles 66 are arranged on the two sides of the roller assembly 5, which can limit the forward and backward movement of the roller assembly 5, so that the roller assembly 5 is stably arranged on the mounting frame 4, that is, the installation is completed.

[0030] Further, the limiting unit 67 comprises a wedge block 672 connected with the mounting frame 4 in a sliding mode, a convex block 673 arranged on the wedge block 672, and a spring 674 arranged between the wedge block 672 and the mounting frame 4, the limiting unit 67 further comprises a sliding groove 671 arranged on the mounting frame 4, and the wedge block 672 is connected with the mounting frame 4 in a sliding mode through the sliding groove 671, and the spring 674 is located in the sliding groove 671.

[0031] It can be understood that when the operator puts the two sides of the roller assembly 5 into the recess 65, the roller assembly 5 extrudes the wedge block 672, the wedge block 672 moves downward, and the spring 674 is compressed, when the roller assembly 5 passes the wedge block 672, the spring 674 resets to drive the wedge block 672 to reset, and the flat part of the wedge block 672 is blocked at the opening of the recess 65, so that the roller assembly 5 cannot be separated from the opening of the recess 65, when the operator needs to disassemble the roller assembly 5, the operator can push the convex block 673 to move downward, the convex block 673 drives the wedge block 672 to move downward, and the spring 674 is compressed, at this time, the wedge block 672 no longer blocks the roller assembly 5, and the operator removes the roller assembly 5 from the recess 65, that is, the disassembly is completed.

[0032] For reference Figure 1 The utility model also provides third embodiment, this embodiment still includes two supports 8 that set up on the both sides of last section bracket 21 respectively on the basis of first embodiment or second embodiment, rotatory connection support shaft 9 between two support 8, support shaft 9 with transmission belt 3 upper inner side contact.

[0033] It can be understood that through the contact between the support shaft 9 and the transmission belt 3, the transmission belt 3 can be supported at the upward angle part when the transmission belt 3 is conveying materials, so that the transmission belt 3 can stably convey materials.

[0034] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0035] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
