DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] Example 1

[0035] See also Figures 1 to 3 As shown, the present invention is a self-lubricating device for mining equipment, comprising an oil storage tank 1 and a cover plate 2 connected to the upper end of the oil storage tank 1, the cover plate 2 being connected to a driving mechanism 3, and a refueling port being provided on the cover plate 2 for facilitating the filling of lubricating oil into the oil storage tank 1.

[0036] like Figures 4-6 As shown, the oil reservoir 1 is fixedly connected to several oil filling cylinders 4, such as the four shown in the figure. The oil reservoir 1 is connected to an oil outlet 101 that is in one-to-one communication with each of the oil filling cylinders 4. Specifically, each of the four oil filling cylinders 4 is connected to the interior of the oil reservoir 1. For example, four pipe sockets 102 are welded or screwed to the bottom wall of the oil reservoir 1. The lower ends of the oil filling cylinders 4 are fixedly connected to the pipe sockets 102, such as by a threaded connection. The oil outlets 101 can be located on the bottom wall of the oil reservoir 1 or on the sidewall below the pipe sockets 102.

[0037] The lower surface of the cover plate 2 is fixedly connected with a limit sleeve 204 that cooperates with the upper end of the oil filling cylinder 4. The cover plate 2 and the oil storage tank body 1 are connected by bolts, and after the connection, the limit sleeve 204 is sleeved on the upper end of the oil filling cylinder 4, thereby improving the fixing effect of the oil filling cylinder 4.

[0038] The side wall of the oil filling cylinder 4 is connected to an oil inlet 400 that communicates with the interior of the oil reservoir 1. Both the oil outlet 101 and the oil inlet 400 are connected to one-way valves, ensuring that lubricating oil can only enter the oil filling cylinder 4 through the oil inlet 400 and can only exit the oil filling cylinder 4 through the oil outlet 101. A piston assembly 401 is mounted within the oil filling cylinder 4. The piston rod of the piston assembly 401 extends through the cover plate 2 and is movably connected to the cover plate 2 via a linear bearing.

[0039] The four piston assemblies 401 are all connected to the reciprocating drive mechanism 5, and the four reciprocating drive mechanisms 5 are all connected to the drive mechanism. The four reciprocating drive mechanisms 5 are synchronously driven by the drive mechanism, and the reciprocating drive mechanism 5 is used to drive the piston assembly 401 to reciprocate, so as to inject the lubricant in the oil storage tank 1 into the lubrication part of the equipment.

[0040] like Figures 7-9 As shown, the reciprocating drive mechanism 5 includes a disc cam 501 rotatably connected to the cover plate 2 and a rocker arm 502 hinged to the cover plate 2. One end of the rocker arm 502 cooperates with the disc cam 501, and the other end is hinged to a pull plate 503, and the other end of the pull plate 503 is hinged to the piston rod of the piston assembly 401.

[0041] A cam groove is provided on the end face of the disc cam 501, and the rocker arm 502 is connected to a follower that cooperates with the cam groove. By rotating the disc cam 501, the cam groove drives the rocker arm 502 to swing back and forth, thereby using the rocker arm 502 and the pull plate 503 to drive the piston assembly 401 to reciprocate in the vertical direction, thereby allowing the lubricating oil to be continuously drawn into the oil filling cylinder 4 from the oil inlet 400 and squeezed out from the oil outlet 101, and transported to various parts of the mining equipment that need lubrication through pipelines.

[0042] The disc cam 501 is fixedly connected to a coaxially arranged rotating shaft, which is rotatably connected to the cover plate 2 through a bearing bracket. The other end of the rotating shaft is fixedly connected to a driven wheel 504 and is transmission-connected to the driving mechanism 3 through the driven wheel 504.

[0043] The driving mechanism 3 includes a transmission shaft 301 rotatably connected to the cover plate 2 and a driving motor 302 in transmission connection with the transmission shaft 301. The transmission shaft 301 is fixedly connected to a driving wheel 303 in one-to-one transmission connection with the driven wheel 504.

[0044] The driven pulley 504 and the driving pulley 303 are synchronous pulleys or sprockets, allowing a single drive motor 302 to synchronously drive the four disc cams 501 to rotate, thereby synchronously driving the four piston assemblies 401 to reciprocate, achieving lubrication. By using a single drive mechanism and the reciprocating drive mechanism 5 to drive the piston assemblies 401 back and forth, the need for the drive motor to reciprocate is eliminated, effectively reducing control difficulty and overall production complexity and costs.

[0045] Example 2

[0046] Based on the first embodiment, Figure 3 、 6 As shown in FIG7 , the rocker arm 502 is slidably connected to the support base 6. The cover plate 2 is slidably connected to the lockable slider 201 through a guide rail, and the lockable slider 201 is hinged to the support base 6.

[0047] Specifically, the support seat 6 includes a sliding sleeve 601 that is sleeved on the outside of the rocker arm 502, so that the sliding sleeve 601 can move axially along the rocker arm 502, and the outer wall of the sliding sleeve 601 is welded or bolted with a connecting ear 602 that is hinged to the locking slider 201.

[0048] By adjusting the position of the locking slider 201 and the support seat 6, the fulcrum of the swing of the rocker arm 502 is changed, and then the swing amplitude of the connection end between the rocker arm 502 and the piston assembly 401 is adjusted. For example, the closer the support seat 6 is to the position of the disc cam 501, the greater the swing amplitude of the connection end between the rocker arm 502 and the piston assembly 401, and vice versa.

[0049] By adjusting the swing amplitude of the rocker arm 502, the reciprocating stroke of the piston assembly 401 is adjusted, thereby adjusting the oil injection amount. In this way, the oil injection amount of each oil injection cylinder 4 can be flexibly adjusted according to the different lubrication requirements of different parts of the mining equipment, thereby improving the overall flexibility and practicality of use.

[0050] Among them, the cover plate 2 is rotatably connected to the screw rod 202 corresponding to the locking slider 201 through the bearing seat, and the locking slider 201 is fixedly connected to the nut 203 cooperating with the screw rod 202. The end of the screw rod 202 is fixedly connected to the knob. The screw rod 202 is rotated by the knob to adjust the position of the locking slider 201, thereby improving the convenience of adjusting the position of the locking slider 201 and the support seat 6. The self-locking properties of the screw rod 202 and the nut 203 can further ensure that the position of the locking slider 201 after adjustment is fixed, so that the overall convenience and reliability are greatly improved.
