[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0014] Example This embodiment describes a centralized oil supply device for the tail section of a self-moving coal mine conveyor belt, such as... Figure 1 As shown, it includes a vertically arranged fixing plate 1. In use, the fixing plate 1 can be fixed to the tail of the machine by welding, which facilitates the subsequent installation of the multi-pass block 6 and the hand pump. The front side wall of the fixed plate 1 is fixed with a connecting block 2 for installing a hand pump. The front side wall of the fixed plate 1 located directly above the connecting block 2 is detachably provided with a multi-pass block 6. The side wall of the multi-pass block 6 is evenly provided with several connecting holes 12 for connecting oil injection pipes from top to bottom, and the connecting holes 12 are all connected to each other. The bottom of the multi-pass block 6 is provided with an oil inlet hole 15 for connecting an oil inlet pipe. The oil inlet hole 15 connects the connecting holes 12, which makes it easy to install the hand pump on the tail of the machine for manual oil supply. The multi-pass block 6 is also used to connect multiple oil injection pipes together, and the oil supply is concentrated through the oil inlet pipe at the bottom of the multi-pass block 6 to improve the oil supply efficiency. Compared with the original oil supply method, if manual oiling of the drums is carried out per shift, it takes about 15 minutes to oil a φ220 drum and about 35 minutes to oil a φ630mm drum using the original oil gun. For a self-moving tail machine with two φ220mm drums and one φ630mm drum, it takes a total of about 65 minutes. With the centralized drum oiling device, it only takes 5 minutes. Therefore, 60 minutes can be saved per shift. Assuming 300 days a year, 300 hours can be saved. At 40 yuan per hour, the annual labor cost can be saved for the mine by about 12,000 yuan, which effectively improves the oil supply efficiency and reduces costs. When using it, the grease fittings at both ends of the roller need to be modified to DN10 connectors. Then, one end of the DN10 pipe is connected to the roller connector, and the other end is connected to the multi-port block 6.

[0015] like Figure 3 As shown, the connecting block 2 is connected to the fixing plate 1 through the fixing block 11. The connecting block 2 located outside the area of ​​the fixing block 11 has a first mounting hole 3 for installing the hand pump, which facilitates the installation of the hand pump and also makes it easy to stagger the position between it and the multi-pass block 6, so as to avoid affecting the installation and disassembly of the multi-pass block 6. The top of the fixing block 11 has a channel for the oil inlet pipe to pass through, which facilitates the connection of the oil inlet pipe to the hand pump and avoids the oil inlet pipe being bent, affecting the oil inlet or even being damaged and leaking.

[0016] like Figure 4 As shown, the front and rear side walls of the multi-channel block 6 are provided with second mounting holes 7 for inserting U-shaped clips. The second mounting holes 7 are connected to the connecting holes 12. The inner side wall of the connecting holes 12 is provided with a limiting groove 13 to prevent the U-shaped clips from falling off. This makes it easier to fix the oil inlet pipe in the connecting holes 12 to prevent it from falling off. This can make the oil supply process more stable and further reduce the workload of operators and maintenance personnel.

[0017] like Figure 2 , Figure 4 and Figure 5As shown, the fixing plate 1 has a third mounting hole 8 for fixing the multi-pass block 6, and a fifth mounting hole 14 connected to and communicating with the multi-pass block 6 is provided on the rear side wall of the multi-pass block 6, which facilitates fixing the multi-pass block 6 on the fixing plate 1, and also facilitates quick disassembly, replacement and maintenance.

[0018] like Figure 1 and Figure 2 As shown, the fixing plate 1 has through slots 4 on both the left and right sides for easy hand holding, which makes it easier and less strenuous for workers to hold during installation and transfer, and also reduces its weight, making it easier to hold.

[0019] The fixing plates 1 located on both the upper and lower sides of the through groove 4 are provided with reserved holes 5 for adding accessories or installing pipe clamps, making them more versatile.

[0020] like Figure 3 As shown, a connecting plate 10 is horizontally fixed to the rear side wall of the fixing plate 1. The connecting plate 10 has a fourth mounting hole 9 for connecting to the tail of the machine, which facilitates connection to the tail of the machine by bolts, thereby facilitating replacement and maintenance. The fixing plate 1 and the connecting plate 10 are integrally formed during manufacturing, which makes their overall strength higher and thus improves their service life.
