[0002] In today's industrial production and transportation, conveyor belts are used to transport and carry materials. Chain conveyors are devices that use chains as traction and carriers to transport materials. They are mainly composed of three parts: a conveyor frame (bracket), a chain, and a power device. The conveyor frame is the main part, the chain is the conveying carrier, and the power device provides power for the operation of the equipment. In order to make the chain run smoothly, reduce the friction between the chain and the sprocket, and reduce the loss between them, the chain is usually lubricated. The existing method is to manually apply lubricating grease to the chain regularly. If the chain is hidden in the bracket, such as the chain conveyor belt in patent CN220431228U, the chain in its structure is inserted into the inside of the limit support plate, that is, its structure is to hide the chain in the limit support plate. When applying lubricating grease, it is necessary to disassemble the parts covering the chain on the bracket to expose the chain, that is, it is necessary to disassemble the limit support plate before applying lubricating grease to the chain. This is very labor-intensive and time-consuming, and has low efficiency. In addition, it is impossible to apply lubricating grease to the chain during the operation of the conveyor belt, which is not conducive to use. Utility Model Content

[0020] The utility model is implemented as follows Figures 1 to 3As shown in the figure, an automatic lubrication device for a conveyor belt includes a base 1 for being installed on a bracket 60 of the conveyor belt corresponding to the position of the chain. The base 1 is a component for installing the entire lubrication device on the conveyor belt. At this time, a bracket through hole is set on the bracket 60 of the conveyor belt at a position opposite to the chain. The base 1 is covered on the bracket through hole. The base 1 and the bracket 60 are detachably connected by screws. For example, the base 1 is set into an n-shaped structure and an extension arm 13 is extended outward at the lower end of both side walls. The base 1 is covered on the bracket through hole, so that there is a gap between the top of the base 1 and the bracket through hole. There is a certain distance between them, which provides installation space for the installation of the oil brush 3 and facilitates the installation of the oil brush 3. Screw holes for installing bolts are set at both radial ends of the through hole of the bracket on the two extension arms 13 and the bracket 60. Then the bolts pass through the screw holes on the lower bracket 60 and the screw holes on the extension arms 13 from bottom to top and are connected with nuts. The base 1 is installed on the bracket 60. The automatic oiler 2 can be detachably installed on the base 1. The automatic oiler 2 can adopt a small nanny automatic oiler. For example, the automatic oiler 2 is set on the top of the base 1, and the top of the base 1 is connected to the bottom of the base 1. A base through hole 10 is provided in which an interface of the grease outlet of the automatic oiler 2 is inserted. The interface of the grease outlet of the automatic oiler 2 is detachably connected with an oil brush 3 for applying grease to the chain. The oil brush 3 is threadedly connected to the interface and passes through the bracket through hole and abuts against the chain. The lubricating grease flows from the automatic oiler 2 to the oil brush 3, and then the oil brush 3 applies the lubricating grease to the chain through the movement of the chain relative to the oil brush 3 to keep the chain lubricated. The oil brush 3 includes a brush handle 30 and bristles 31 arranged on the brush handle 30. The brush handle 30 is provided with a accommodating cavity 300. The accommodating chamber 300 is connected to the interface of the grease outlet of the automatic lubricator 2. At this time, a base through hole 10 for installing the automatic lubricator is set on the base 1. The automatic lubricator 2 and the oil brush 3 are connected through a conversion joint 4. The base through hole 10 is a circular through hole. The interface of the automatic lubricator 2 passes through the base through hole 10 and extends into the accommodating chamber 300. The conversion joint 4 is a cylindrical structure, and its upper part is provided with an internal thread that is threadedly connected to the interface of the automatic lubricator 2, and its lower part is provided with an external thread that is threadedly connected to the oil brush 3. The outer diameter of the conversion joint 4 is larger than the diameter of the base through hole 10;First, the base 1 is put on the interface of the automatic oiler 2 using the base through hole 10, and then one end of the conversion joint 4 is threadedly connected to the interface of the automatic oiler 2, and the top of the conversion joint 4 is pressed against the inner top wall of the base 1, and the other end of the conversion joint 4 is threadedly connected to the brush handle 30. An internal threaded through hole threadedly connected to the external thread of the conversion joint 4 is provided on the inner top wall of the accommodating chamber 300, and the oil brush 3 is threadedly connected to the conversion joint 4 using the internal threaded through hole, which facilitates the connection and installation between the oil brush 3, the base 1 and the automatic oiler 2, and the cavity wall of the accommodating chamber 300 is provided with an oil outlet through hole at the position corresponding to the bristles 31 301, there are multiple oil outlet holes 301, and they are staggered with the bristles 31 at the bottom of the brush handle 30, so that the automatic oiler 2 injects the lubricating grease into the accommodating chamber 300, and then flows out from the accommodating chamber 300 to the bristles 31 through the oil outlet holes 301, and the lubricating grease is applied to the chain through the bristles 31; the lower part of the accommodating chamber 300 is an inverted trapezoidal structure, and the size of the inner bottom surface of the accommodating chamber 300 is equivalent to the surface size occupied by the bristles on the bottom surface of the brush handle 30, which avoids the accumulation of lubricating grease in the accommodating chamber 300, and can more evenly and comprehensively inject the lubricating grease to the bristles 31 for application. The oil brush 3 is a square oil brush, that is, the bristle width of the bristles 31 in the moving direction of the chain is equivalent to the width of the chain, so that the lubricating grease can be applied to the chain more evenly. In this way, without disassembling the support 60 of the conveyor belt, the hidden chain on the conveyor belt can be conveniently smeared with lubricating grease, which improves efficiency. The lubricating grease can be applied at a specified time through the setting on the automatic oiler 2, ensuring the smooth operation of the conveyor belt. The base 1 can also be conveniently installed on the support of the conveyor belt without causing structural changes to the conveyor belt body, which is convenient and practical. ;

[0021] Further progress, such as Figure 3As shown in the figure, the base 1 includes a fixed part 11 for being installed on a bracket 60 of the conveyor belt, a sliding part 12 which slides up and down the fixed part 11, and the automatic oiler 2 is installed on the sliding part 12, so that the automatic oiler 2 and the oil brush 3 can move up and down relative to the chain, and then can be used to adjust the distance of the oil brush 3 relative to the chain. When oiling, the oil brush 3 is lowered so that the oil brush 3 and the chain are in contact. When oiling is not needed, the oil brush 3 is raised to avoid the influence of the oil brush 3 on the chain when oiling is not needed, thereby ensuring the smooth movement of the chain. For the limited sliding structure between the fixed part 11 and the sliding part 12, a vertical slide groove 110 is provided on the fixed part, a lead screw is provided in the slide groove 110, the sliding part 12 is connected to the lead screw nut 112 of the lead screw, the lead screw is composed of a lead screw 111 and a lead screw nut 112 sleeved on the lead screw 111, the lead screw 111 is driven by a driving motor 113 provided on the fixed part 11 to rotate in the slide groove 110, the lead screw nut 112 is matched and installed in the slide groove 110 and part of it protrudes out of the slide groove 110, the lead screw nut 112 moves up and down in the slide groove 110 with the rotation of the lead screw 111, and the sliding part 12 is connected to the part of the lead screw nut 112 protruding from the slide groove 110; at this time, it is also possible to adopt the method of not providing a driving motor 113, but to drive its rotation by a hand wheel connected to the lead screw 111 and rotating the hand wheel.

[0022] Further progress, such as Figure 1 and Figure 3 As shown in the figure, it also includes a transparent window 5 for viewing the running condition of the conveyor belt chain. The transparent window 5 can be set on the bracket 60 of the conveyor belt corresponding to any position of the chain, and can also be set on the base 1. The running condition of the conveyor belt chain can be seen intuitively through the transparent window 5. When the conveyor belt chain has uneven lubrication, insufficient lubrication or other faults, it can be observed in time and repaired in time.

[0023] A conveyor belt, such as Figure 4 As shown in , it includes a conveyor belt body 6, and a bracket 60 of the conveyor belt body 6 is provided with an automatic lubrication device for the conveyor belt as described in any of the above items.
