Description

[0001] The invention relates to the technical field of conveyors, in particular to an automatic lubrication device for conveyors. Background Art

[0002] In agricultural production and processing, conveyors are important equipment for transporting agricultural products and are widely used in various production lines and processing procedures. However, after a period of use, key components such as bearings of traditional conveyors will gradually wear out due to friction. In order to ensure the normal operation of the conveyor and extend its service life, these components must be lubricated regularly.

[0003] At present, most conveyors still rely on manual operation for lubrication, that is, workers need to manually add grease regularly. This lubrication method has many shortcomings: first, the filling efficiency is low, because workers need to check and fill each bearing one by one, which is not only time-consuming and labor-intensive, but also increases the workload of workers. Secondly, there is a risk of forgetting to fill manually, and it is easy to ignore the lubrication maintenance of the conveyor, which leads to accelerated wear of the bearings due to lack of lubrication, and even causes failures, seriously affecting production efficiency and the service life of the equipment.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0037] Example 1

[0038] See also Figure 1-Figure 12 , the present invention provides a technical solution:

[0039] A conveyor automatic lubrication device includes a conveyor body 1 and two drive shafts 2 rotatably mounted at both ends of the conveyor body 1 through bearings. The conveyor body 1 and the drive shaft 2 are both common existing structures and will not be described in detail herein. The device also includes:

[0040] A plurality of filling pipes 10, wherein the plurality of filling pipes 10 are respectively arranged at both ends of the conveyor body 1, and each of the filling pipes 10 is directly opposite to the adjacent bearing;

[0041] Two piston plates 11, the two piston plates 11 are respectively arranged at two ends of the conveyor body 1;

[0046] The transmission assembly 6 includes a second sliding frame 61 arranged on the fixed bracket 33, an output rack 62 is slidably arranged in the second sliding frame 61, a fixed shaft 63 is rotatably arranged on the fixed bracket 33, the fixed shaft 63 and the rotating shaft 55 are arranged coaxially, a one-way rotating member 7 is arranged between the fixed shaft 63 and the rotating shaft 55, so that the fixed shaft 63 rotates when the rotating shaft 55 rotates counterclockwise, and a stroke adjusting member 8 is arranged on the fixed bracket 33, which is used to adjust the moving distance of the output rack 62 when the fixed shaft 63 rotates;

[0047] The one-way rotating member 7 includes a ratchet wheel 71 disposed on the fixed shaft 63, and the ratchet wheel 71 is provided with ratchet teeth 72 meshing with the ratchet wheel 71, and the rotating shaft 55 is provided with an elastic member 73 for realizing the resetting work of the ratchet teeth 72;

[0048] The elastic member 73 includes a rotating rod 74 disposed on the rotating shaft 55, a round rod 75 is disposed on the rotating rod 74, the ratchet 72 is rotatably disposed at the end of the round rod 75, a torsion spring 76 is sleeved on the outer side of the round rod 75, and the two ends of the torsion spring 76 are respectively connected to the rotating rod 74 and the ratchet 72;

[0049] The stroke adjustment member 8 includes an input gear 81 arranged on the fixed shaft 63, a mounting shaft 82 is rotatably arranged on the fixed bracket 33, a first crown gear 83 meshing with the input gear 81 is rotatably arranged on the mounting shaft 82 through a bearing, an output gear 84 meshing with the output rack 62 is arranged on the mounting shaft 82, a third crown gear 85 meshing with the output gear 84 is rotatably arranged on the fixed shaft 63 through a bearing, and a plurality of second crown gears 86 are rotatably arranged on the fixed shaft 63 and the mounting shaft 82 respectively through bearings, the second crown gear 86 close to the first crown gear 83 meshes with the first crown gear 83, the second crown gear 86 close to the third crown gear 85 meshes with the third crown gear 85, and two second crown gears 86 located in the middle mesh in sequence;

[0050] The filling member 9 includes a storage box 91 arranged on the mounting bracket 31, the piston plate 11 is slidably arranged in the storage box 91, and the multiple filling pipes 10 are respectively arranged at the bottom of the storage box 91. A connecting bent rod 92 is arranged on the output rack 62, and the connecting bent rod 92 is connected to the piston plate 11.

[0051] When the conveyor body 1 starts to work, the staff puts the agricultural products on it and starts the conveying work. At the same time, the driving shafts 2 at both ends thereof rotate accordingly. The pulleys 41 arranged on the driving shaft 2 are connected with the pulleys 41 on the transmission shaft 32 through the synchronous belt 42 to realize synchronous rotation. The rotating rod 53 arranged on the transmission shaft 32 drives the deflection rod 54 to rotate. The other end of the deflection rod 54 is rotationally connected with the shift block 52 arranged on the sliding frame 1 51. With the rotation of the transmission shaft 32, the deflection rod 54 pushes the shift block 52 to slide on the sliding frame 1 51, thereby driving the transmission rack 34 to move.

[0052] The transmission rack 34 meshes with the transmission gear 56 disposed on the rotating shaft 55. When the transmission rack 34 moves downward, the transmission gear 56 is driven to rotate counterclockwise and mesh with the ratchet 72 on the ratchet 71. Due to the one-way transmission characteristics of the ratchet 71 and the ratchet 72, when the rotating shaft 55 rotates counterclockwise, the ratchet 71 drives the fixed shaft 63 to rotate. The reset of the ratchet 72 is achieved by the torsion spring 76 disposed on the rotating shaft 55. When the rotating shaft 55 rotates clockwise, the fixed shaft 63 cannot rotate therewith due to the arrangement of the ratchet 71 and the ratchet 72.

[0053] The input gear 81 on the fixed shaft 63 meshes with the first crown gear 83 on the mounting shaft 82. Under the transmission of the second crown gear 86, the third crown gear 85 finally drives the output gear 84 to rotate. The output gear 84 meshes with the output rack 62 in the second sliding frame 61. As the output gear 84 rotates, the output rack 62 slides in the second sliding frame 61. The connecting bent rod 92 provided on the output rack 62 is connected to the piston plate 11. As the output rack 62 moves, the piston plate 11 slides in the storage box 91. When the piston plate 11 moves downward, the grease in the storage box 91 is pushed into the adjacent bearing through the filling pipe 10 to achieve automatic lubrication.

[0054] Since the automatic lubrication unit 3 is connected to the drive shaft 2, the lubrication cycle is synchronized with the operating state of the conveyor body 1, and no additional control device is required. As the conveyor body 1 continues to run, the automatic lubrication device continuously adds grease to the bearing to ensure a good lubrication state of the bearing.

[0055] Example 2

[0056] See also Fig.13 , the present invention provides a technical solution:

[0057] Different from the first embodiment, a protective cover 12 is provided at one end of the conveyor body 1, and a straight slot for connecting the bending rod 92 for displacement adjustment is opened on the protective cover 12.

[0058] The provision of the protective outer cover 12 ensures that the conveyor body 1 will not affect the normal operation of precision instruments when conveying agricultural products, thereby ensuring the service life of the automatic lubrication device.
