Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a coal speed reducer box body which is convenient to clean. Background Technique

[0002] The speed reducer box body is a basic component for installing each transmission shaft; since relatively large reaction forces are generated when each shaft transmits torque during the operation of the speed reducer and act on the box body, it is required that the box body has sufficient rigidity to ensure the relative position accuracy of each transmission shaft. A metal structure box body can obtain greater strength and rigidity;

[0003] The cleaning of the parts inside the speed reducer is a very important process during the maintenance process. Cleanliness is a key factor in ensuring the maintenance quality. The traditional cleaning method of the speed reducer box body is mainly to remove the whole box body and then clean the internal parts. The method is relatively complex and cumbersome;

[0004] In this regard, the publicity document: CN209469778U, named "a speed reducer box body which is convenient to clean", includes a box body and a box cover. The box cover is detachably connected to the top of the box body. A cleaning port is opened on the top of the box cover. A flow channel is opened at one end of the cleaning port. A seamless steel pipe is welded at one end of the flow channel. A rotating nozzle is detachably connected to the surface of the seamless steel pipe. A baffle is fixedly connected below the nozzle. A fan is rotatably connected to one side of the baffle. An electric heating mesh is connected to one side of the fan by screws. A boss is fixedly connected to the bottom surface of the box cover. A groove is opened at one end of the box body. A water-swellable water-stop rubber strip is adhered to the inner wall of the groove. The utility model accesses an external water pipe through the cleaning port. The cleaning water enters the seamless steel pipe through the flow channel. The rotating nozzle rotates under pressure to clean the oil stains and dust attached to the surface of the parts inside the box body, which can effectively improve the cleaning efficiency.

[0005] Although the above-mentioned existing speed reducer box body reduces the cleaning difficulty, it greatly changes the structure of the box body itself, has many accessories, high cost, and is easy to affect the normal installation of the internal parts of the speed reducer. Moreover, the sewage pipe of the box body is welded to the box body and protrudes outside the box body, which is easy to affect the normal placement and installation of the box body; Therefore, it does not meet the existing requirements, and for this reason, we propose a coal speed reducer box body which is convenient to clean.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1-4, an embodiment provided by the present utility model: a coal reducer box body convenient for cleaning, comprising: a reducer box body 1, positioning blocks 12 are arranged at the four corners of the reducer box body 1, positioning holes 13 are opened on the outer walls of the positioning blocks 12, and bolt-like components are installed at the positioning holes 13. The reducer box body 1 can be installed and combined with other components through the positioning blocks 12 and the positioning holes 13; an upper water inlet component 16 is arranged above the reducer box body 1. The upper water inlet component 16 includes a box body cover plate 2, and the box body cover plate 2 is detachably installed at the upper opening of the reducer box body 1 through bolts. The box body cover plate 2 is of a detachable design. When it is necessary to repair and observe the conditions inside the box, the upper opening can be exposed to the outside by removing the box body cover plate 2, enabling users to repair, replace and observe the parts inside the box through the upper opening. Through holes 14 are opened on the outer walls at both ends of the reducer box body 1, and covers 15 are arranged on the outer walls of the through holes 14. The through holes 14 are used for the combined penetration of the internal parts of the reducer and external components. During cleaning, the through holes 14 are blocked by the covers 15, so that the water body is restricted inside. As the water body increases, it soaks the parts to clean the internal parts. A magnetic suction groove 5 is opened on the upper surface of the box body cover plate 2, and a water connection pipe head 4 is arranged inside the magnetic suction groove 5. An internal guiding component 18 is arranged inside the reducer box body 1. The internal guiding component 18 includes inclined guiding blocks 6 located on both sides inside the box. A through-hole water filtering layer 7 is arranged between the inclined guiding blocks 6, and a lower drainage component 17 is arranged below the through-hole water filtering layer 7; the water connection pipe head 4 is installed in the magnetic suction groove 5 and does not protrude outside the device, so it will not affect the normal placement and installation of the reducer. The water connection pipe head 4 is used to connect a water delivery pipeline. The water body is connected and conveyed into the box body through the water delivery pipeline to clean the inside. After cleaning, the water delivery pipe is separated from the water connection pipe head 4, achieving the effect of facilitating the assembly and disassembly for users. The water body falls from top to bottom to clean the inside of the box. The water body is guided to the through-hole water filtering layer 7 by the inclined guiding blocks 6. A number of holes are opened at the through-hole water filtering layer 7, and the water body falls from the holes into the sewage discharge layer 8 below for centralized collection;

[0023] The lower drainage assembly 17 includes a sewage discharge layer 8, and the sewage discharge layer 8 is arranged directly below the through-hole water filtration layer 7. A threaded groove 10 is formed on the outer wall of the sewage discharge layer 8, and a sewage discharge pipe 11 is arranged inside the threaded groove 10, and one end of the sewage discharge pipe 11 is communicated with the sewage discharge layer 8; the sewage discharge pipe 11 is embedded in the threaded groove 10 so that it will not protrude outside the box body, which can avoid affecting the installation and placement of the box body. The sewage discharge pipe 11 can also be externally connected with a water pipe in a sleeved manner for conveying operation, so that the water body inside the sewage discharge layer 8 can be discharged outside the box body through the sewage discharge pipe 11; through the settings of the upper water inlet assembly 16, the inner guiding assembly 18, and the lower drainage assembly 17 at the reducer box body 1, the inside is cleaned by water inlet, and after cleaning, the water body is guided to the lower drainage assembly 17 by the inner guiding assembly 18, and finally discharged to the outside through the lower drainage assembly 17, making the reducer box body 1 more convenient to clean, with fewer required accessory structures, lower costs, and not affecting the normal placement and installation of internal parts, nor affecting the normal placement and installation outside the box body, thus facilitating user use;

[0024] A sewage discharge cover 9 that is threadedly matched with it is installed on the outer wall of the threaded groove 10, and a magnetic attraction cover 3 that is magnetically connected with it is arranged above the magnetic attraction groove 5; the sewage discharge cover 9 is used to protect the internal sewage discharge pipe 11, avoid impurities entering and causing blockage, and play a sealing role. When cleaning and filling water in the box, through the threaded connection method, the sewage discharge cover 9 can be fixed more stably and firmly at the threaded groove 10, improving the sealing effect; the magnetic attraction cover 3 is adsorbed and fixed on the magnetic attraction groove 5 by magnetic attraction, so that it can seal the water inlet during daily placement. When cleaning is required, it can be very conveniently removed for pipe connection operation.

[0025] Working principle: When in use, the magnetic attraction cover 3 is opened, the water delivery pipe is connected to the water connection head 4, and water is delivered to clean the inside of the box body. The water body is guided to the through-hole water filtration layer 7 by the inclined guide block 6. A number of holes are formed in the through-hole water filtration layer 7, and the water body falls from the holes into the sewage discharge layer 8 below for centralized collection. The sewage discharge pipe 11 can also be externally connected with a water pipe in a sleeved manner for conveying operation, so that the water body inside the sewage discharge layer 8 can be discharged outside the box body through the sewage discharge pipe 11.
