DETAILED DESCRIPTION

[0018] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] Example 1

[0020] A device for preventing mud cake accumulation in on-site sewage treatment vehicles, such as Figure 1As shown, it includes a mounting base 1, and grooves are provided on the left and right sides of the middle part of the mounting base 1 to facilitate the lifting of the lifting member 81. The front and rear parts of the mounting base 1 are rotatably connected to the rotating shaft 3, and a contact belt 2 is wound between the rotating shafts 3. The left and right sides of the front rotating shaft 3 are connected to the missing gear 4, and the left and right sides of the mounting base 1 are slidably connected to the rack rod 5, and the rack rod 5 is connected to a limiting block. The rack rod 5 is meshed with the adjacent missing gear 4, and the rack rod 5 is provided with a first spring 6. A push plate 7 is connected between the rack rods 5, and the push plate 7 is slidably connected to the mounting base 1. A tensioning mechanism 8 is provided on the mounting base 1.

[0021] like Figure 1 and Figure 2 As shown, the tensioning mechanism 8 includes a fixed frame 83, and the fixed frames 83 are connected to the left and right sides of the mounting seat 1. The fixed frames 83 are slidably connected to the lifting members 81, and the lifting members 81 are contact-connected to the contact belt 2. A second spring 84 is connected between the lifting members 81 and the adjacent fixed members, and a roller shaft 82 is rotatably connected between the lifting members 81.

[0022] It should be noted that the on-site sewage treatment vehicle is a mobile sewage treatment equipment, which is mainly used for sewage treatment tasks in temporary or emergency situations, at construction sites, disaster relief sites or remote areas where there are no fixed sewage treatment facilities. The mud cake of the sewage treatment vehicle refers to the solid waste generated in the sewage treatment process, which is usually formed after sludge dehydration. First, the device is installed on the lower side of the conveyor belt of the sewage treatment vehicle mud cake treatment system. The conveyor belt drives the contact belt 2 to rotate, drives the rotating shaft 3 to rotate, and then makes the missing gear 4 rotate, thereby driving the rack rod 5 to move. When the missing gear 4 is engaged with the rack rod 5, the missing gear 4 is engaged with the rack rod 5. The gear 4 drives the rack rod 5 to move forward, driving the push plate 7 to slide forward, and the first spring 6 is stretched. When the gear 4 is out of engagement with the rack rod 5, the first spring 6 is reset, driving the rack rod 5 to reset, and at the same time driving the push plate 7 to reset. In the initial state, the second spring 84 is in a compressed state. In order to make the contact belt 2 fit the conveyor belt in the mud plate system, the reaction force of the second spring 84 drives the lifting member 81 to move upward, so that the lifting member 81 fits the contact belt 2 with the conveyor belt, thereby facilitating the normal operation of the device, thereby assisting the discharge of the mud plate and preventing the accumulation of mud plates, so that the sewage treatment vehicle can operate normally.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 3As shown, a cleaning mechanism 9 is also included, and the cleaning mechanism 9 includes a mounting member 92. The mounting members 92 are connected to the left and right sides of the mounting seat 1, and a blocking plate 91 is connected between the mounting members 92. A sliding member 93 is slidably connected to the blocking plate 91 for scraping the surface of the push plate 7. The sliding member 93 is a C-shaped structure that fits the push plate 7.

[0025] It should be noted that, since the push plate 7 is slidably connected to the mounting base 1, when the push plate 7 moves forward, there is a gap between the push plate 7 and the contact belt 2. The blocking plate 91 can block the push plate 7 and the mud plate, thereby preventing the mud plate from falling to the lower part of the contact belt 2 and affecting the normal operation of the device. When there is mud plate residue on the surface of the push plate 7, the operator can slide the sliding member 93. The C-shaped structure of the sliding member 93 fits the surface of the push plate 7 more closely, thereby scraping off the mud plate on the surface of the push plate 7.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
