[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] REFERENCE Figs. 1 to 3The utility model provides an embodiment: a kind of watering tank for road roller, including water storage tank 1, important function of storing water is borne, and water storage tank 1 uses rotational moulding process, water capacity is large, streamline design, water flow is more smooth. The rear end of water storage tank 1 is fixedly connected with expansion tank 2, it provides additional space for water storage tank 1, so that the water storage capacity of entire water tank is increased, and process is identical with water storage tank 1. The front end of water storage tank 1 is fixedly connected with visual window 3, which is made of tempered glass. Water level condition in water storage tank 1 can be directly observed by visual window 3 by operator, without additional measuring tool, so as to be able to understand the water amount in water tank in time, so as to add water in time when needing, guarantee the continuity of road roller watering operation. The top end of water storage tank 1 is threadedly connected with the rotating assembly that covers water storage tank 1, and the rotating assembly includes threaded cover 4, the specification of the thread of threaded cover 4 is matched with the thread of the inner wall of the top end of water storage tank 1, to ensure the tight connection between the two;

[0020] The outer thread of threaded cover 4 is connected in the inner wall of the top end of water storage tank 1, threaded cover 4 can effectively prevent water leakage in water tank when being tightened, and when needing to be opened, it can be realized by rotating operation, which is convenient for water tank maintenance work such as adding water and cleaning. Threaded water inlet hole 5 is provided on the top side of water storage tank 1, which provides a threaded groove for the installation of threaded cover 4, and facilitates the water filling of the interior of water storage tank 1. The inner wall of the top end of water storage tank 1 is fixedly connected with sealing ring 6, which provides a stable basis for subsequent sealing operation. The inner wall of the top end of water storage tank 1 is fixedly connected with spring 7, which is fixed to spring 7, so that spring 7 can be uniformly stressed;

[0021] The top end of spring 7 is fixedly connected with sealing ring 8, by compressing spring 7, spring 7 can store elastic potential energy, and then give sealing ring 8 a force in the opposite direction to resist threaded cover 4, so that sealing ring 8 can be tightly fitted with threaded cover 4, thereby improving the sealing effect. The outer side wall of sealing ring 8 is slidingly connected to the inner wall of the top end of water storage tank 1, and the inner wall of sealing ring 8 is slidingly connected to the outer side wall of sealing ring 6. The double sliding connection and the cooperation of sealing ring 6 and sealing ring 8 further enhance the sealing effect around the water inlet hole, effectively prevent water from leaking from the water inlet hole, and ensure the sealing performance of water storage tank 1 during use.

[0022] Working principle: connect the external water injection equipment (such as water pipe) with the threaded water inlet hole 5, water enters the water storage tank 1 through the threaded water inlet hole 5 under the action of pressure, and then flows to the inside of the expansion tank 2, and the water storage tank 1 and the expansion tank 2 are made by using the rotational molding process, have large water capacity, streamline design, and smoother water flow. When the water level is observed to reach the appropriate height through the visible window 3, stop water injection, and then remove the water injection equipment from the threaded water inlet hole 5. Before or during the operation of the road roller, the operator directly observes the water level in the water storage tank 1 through the visible window 3. If the water level is too low, prepare to add water. When water needs to be added or the water tank needs to be cleaned and other maintenance work is needed, rotate the threaded cover 4 so that it gradually loosens along the threads on the inner wall of the top end of the water storage tank 1 until the threaded cover 4 can be completely opened, so that the inside of the water tank can be operated accordingly. After completing the water adding or maintenance, align the threaded cover 4 with the threads on the inner wall of the top end of the water storage tank 1, and then rotate the threaded cover 4 so that it gradually tightens until the water storage tank 1 is completely sealed. During the tightening process, the threaded cover 4 is tightly attached to the inner wall of the top end of the water storage tank 1, and at the same time the sealing ring 8 is in close contact with the threaded cover 4 under the action of the spring 7, ensuring good sealing effect.

[0023] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
