[0043] As shown in the accompanying drawings for purposes of the present disclosure Figures 1-9 The utility model provides a technical scheme:

[0044] The utility vehicle garbage anti-overflow device comprises a utility vehicle 1, an anti-overflow plate 2 and a discharging plate 3 installed on the utility vehicle 1; wherein: the vehicle compartment of the utility vehicle 1 is a semi-closed vehicle compartment, and an inlet 12 and a discharging port 13 are respectively arranged on the tail end of the vehicle compartment vertical plate 11; the inlet 12 is arranged at the middle of the upper end of the vehicle compartment vertical plate 11, and is used for pouring garbage in the garbage can into the vehicle compartment through the inlet 12 during use; the discharging port 13 is arranged at the lower end of the vehicle compartment vertical plate 11, and is used for discharging garbage in the vehicle compartment during use; the anti-overflow plate 2 is rotatably installed at the inlet 12 through a hinge arranged on the vehicle compartment vertical plate 11 and an adjusting piece 4, and is used in cooperation with an electromagnetic limiting assembly 9 arranged on the vehicle compartment cover, so that the anti-overflow plate 2 can be tightly installed at the inlet 12, thereby achieving the anti-overflow effect during transportation; the discharging plate 3 is rotatably installed at the discharging port 13 through a hinge arranged on the vehicle compartment vertical plate 11 and an adjusting piece 4, and is used in cooperation with an electromagnetic clamping assembly 6 arranged on the chassis of the utility vehicle 1, so that the discharging plate 3 can be tightly pressed outside the discharging port 13, thereby achieving the anti-overflow effect during transportation.

[0045] In the above description, the semi-closed arrangement of the vehicle compartment effectively avoids the problem of garbage and garbage odor overflowing during collection and transportation, and the vehicle compartment is installed on the vehicle frame through a hydraulic jacking system (prior art, not shown in the figure), so that the vehicle compartment can be tilted by the hydraulic jacking system to discharge garbage. By arranging the inlet 12 at the middle of the upper end of the vehicle compartment vertical plate 11, the inlet 12 can be opened by controlling the anti-overflow plate 2 to rotate downward along the hinge point through the adjusting piece 4 during use, thereby facilitating feeding into the vehicle compartment through the inlet 12, and the inlet 12 can be closed by controlling the anti-overflow plate 2 to rotate upward along the hinge point through the adjusting piece 4 after feeding is completed, thereby avoiding garbage and garbage odor from overflowing. By arranging the discharging port 13 and the discharging plate 3, the discharging port 13 can be opened by controlling the discharging plate 3 to rotate upward along the hinge point through the adjusting piece 4 during use, thereby facilitating garbage discharge by tilting the vehicle compartment through the hydraulic jacking system, and the discharging port 13 can be closed by controlling the discharging plate 3 to rotate downward along the hinge point through the adjusting piece 4 after discharging is completed, thereby avoiding garbage and garbage odor from overflowing.

[0046] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the adjusting piece 4 is a hydraulic telescopic rod, and is connected to a hydraulic pump 5 through a hydraulic hose; during use, the adjusting piece 4 is controlled to extend or retract through the hydraulic pump 5, thereby driving the anti-overflow plate 2 and the discharging plate 3 to rotate, opening the inlet 12 and / or the discharging port 13, and performing feeding or discharging operations.

[0047] In a preferred embodiment, as shown inFigure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown in the drawings, one end of the adjusting piece 4 is rotatably connected with the discharge plate 3 through the first hinged support 7, and the other end is rotatably connected with the anti-overflow plate 2 through the second hinged support 8.

[0048] In the above description, the first hinged support 7 is fixedly installed on the discharge plate 3 and is an I-shaped support including a base plate 71 and a top plate 72. The base plate 71 is installed on the discharge plate 3 through positioning pins, and the top plate 72 is installed at the top end of the base plate 71. Symmetrical ear plates 73 are arranged on the top plate 72, and the adjusting piece 4 is rotatably connected with the ear plates 73 through a pin shaft and is located between the two ear plates 73. The second hinged support 8 is installed on the anti-overflow plate 2 through positioning pins, and the ear plate thereof is rotatably connected with the adjusting piece 4 through a pin shaft. The I-shaped arrangement of the first hinged support 7 enables the adjusting piece 4 to always be at an inclined angle, which facilitates the rotation of the anti-overflow plate 2 and the discharge plate 3 through the extension of the adjusting piece 4.

[0049] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The electromagnetic clamping assembly 6 is installed on the lower side of the sanitation vehicle 1 chassis and includes a clamping hook 61, a pull rod 63, a first permanent magnet 64, and a first electromagnet 66. The clamping hook 61 is rotatably installed on the lower side of the sanitation vehicle 1 chassis through a rotating shaft 62 and is used in cooperation with the discharge plate 3. The clamping hook 61 can limit the bottom of the discharge plate 3 so that the discharge plate 3 tightly abuts against the side wall of the carriage of the discharge port 13, thereby avoiding the overflow of garbage and garbage odor. The pull rod 63 is installed at the other end of the clamping hook 61, and the other end of the pull rod 63 is fixedly connected with the first permanent magnet 64. The first permanent magnet 64 is slidably arranged in a mounting box 14 on the lower side of the sanitation vehicle 1 chassis and is used in cooperation with the first electromagnet 66. The first electromagnet 66 is fixedly installed in the mounting box 14 and can attract the first permanent magnet 64 after being electrified.

[0050] In the above description, after the first electromagnet 66 is energized, the card hook 61 is driven to rotate due to the repulsion between the first electromagnet 66 and the first permanent magnet 64, thereby achieving clamping and releasing of the discharge plate 3; the pull rod 63 is a flexible pull rod such as a steel wire, which is used to provide space for the card hook 61 when the card hook 61 rotates, and the pull rod 63 further penetrates the side wall of the mounting box 14 and can move along the side wall of the mounting box 14; the spring 65 is further arranged on the side of the first permanent magnet 64 away from the first electromagnet 66, one end of the spring 65 is connected to the inner wall of the mounting box 14, and in the normal state, the card hook 61 is tightly pressed against the outer side of the discharge plate 3; when the first electromagnet 66 is energized to drive the first permanent magnet 64 to move, the spring 65 is elongated, thereby facilitating the resetting of the card hook 61 through the restoring deformation of the spring 65 after use.

[0051] In use, when it is necessary to open the discharge port 13 for unloading, the controller installed in the control room at the front end of the sanitation vehicle 1 is used to control the energization of the first electromagnet 66, after the first electromagnet 66 is energized, the first electromagnet 66 drives the first permanent magnet 64 to move in the mounting box 14 due to the repulsion between the first electromagnet 66 and the first permanent magnet 64, the spring 65 is elongated, and the card hook 61 is driven to rotate, thereby achieving the release of the discharge plate 3; then, the control and adjustment member 4 is retracted in cooperation, thereby driving the discharge plate 3 to rotate and unloading the discharge port 13; conversely, the discharge port 13 is closed.

[0052] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the electromagnetic limiting component 9 includes a plug block 91 and a locking block 92 matched with each other, the plug block 91 is installed on the anti-overflow plate 2 through a positioning bolt, and a second permanent magnet 912 is arranged on the inner side of a plug rod 911 of the plug block 91; the locking block 92 is installed on the upper side of the compartment plate of the vehicle compartment through a positioning bolt, and a second electromagnet 922 is arranged on the inner side of each of two baffle plates 921 of the locking block 92 and is used in cooperation with the second permanent magnet 912.

[0053] In the above description, when the anti-overflow plate 2 is rotated to drive the plug rod 911 to be inserted into the insertion slot between the two baffle plates 921, the second electromagnet 922 can be repulsed with the second permanent magnet 912 by energizing the second electromagnet 922, thereby achieving the fixation of the plug block 91 and the stability of the installed anti-overflow plate 2, and avoiding the overflow of garbage and garbage odor at the feeding port 12.

[0054] In use, when it is needed to open the feeding port 12 for feeding, first, the second electromagnet 922 is controlled to be powered off by the controller installed in the front end control chamber of the sanitation vehicle 1, so that the mutual attraction between the plug block 91 and the locking block 92 disappears; then the control adjusting part 4 is controlled to shrink, the anti-overflow plate 2 is driven to rotate, and feeding is carried out through the feeding port 12; conversely, the feeding port 12 is closed.

[0055] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in order to ensure the sealing performance of the feeding port 12 and the discharging port 13 after the anti-overflow plate 2 and the discharging plate 3 are installed, sealing rings are further installed on the opening side walls of the feeding port 12 and the discharging port 13 and are used in cooperation with the sealing rings arranged on the feeding port 12 and the discharging port 13, so as to ensure the sealing performance of the feeding port 12 and the discharging port 13 after the anti-overflow plate 2 and the discharging plate 3 are installed.

[0056] The working principle of the sanitation vehicle garbage anti-overflow device is as follows:

[0057] Scenario 1: When the sanitation vehicle 1 needs to be fed, the second electromagnet 922 is powered off by the controller installed in the front end control chamber of the sanitation vehicle 1, so that the mutual attraction between the plug block 91 and the locking block 92 disappears; then the control adjusting part 4 is controlled to shrink, the anti-overflow plate 2 is driven to rotate, and feeding is carried out through the feeding port 12; and after feeding, the anti-overflow plate 2 is controlled to rotate by controlling the process opposite to the above process, the feeding port 12 is closed, and the overflow of garbage and garbage odor at the feeding port 12 in the transportation process is avoided.

[0058] Scenario 2: When the sanitation vehicle 1 needs to be discharged, the first electromagnet 66 is powered on by the controller installed in the front end control chamber of the sanitation vehicle 1, after the first electromagnet 66 is powered on, the first permanent magnet 64 is driven to move in the installation box 14 by the attraction between the first electromagnet 66 and the first permanent magnet 64, the spring 65 is elongated, and the clasp 61 is driven to rotate, so that the discharging plate 3 is released; then the control adjusting part 4 is controlled to shrink, the discharging plate 3 is driven to rotate, and the discharging port 13 is discharged; and after discharging, the discharging plate 3 is controlled to rotate by controlling the process opposite to the above process, the discharging port 13 is closed, and the overflow of garbage and garbage odor at the discharging plate 3 in the transportation process is avoided.

[0059] It should be noted that in the above description, the controller, the hydraulic pump 5, the first electromagnet 66 and the second electromagnet 922 are all relatively mature devices in the prior art, and the specific models can be selected according to actual needs, and the specific power supply mode can be selected to use mains power or a mobile power supply, which will not be described here.
