[0030] The utility model provides a septic tank suction head filtering device for a septic tank suction truck, comprising a filter cartridge 1, a feed pipe 11 installed at one end of the filter cartridge 1, a first discharge pipe 12 installed at the bottom of the filter cartridge 1, and a second discharge pipe 13 installed at one end of the filter cartridge 1 away from the feed pipe 11, and further comprising: a filter component 2, the filter component 2 comprising two mounting frames 21 slidably arranged in the filter cartridge 1, both mounting frames 21 being rotatably connected to mounting frames 22, and the two mounting frames 22 being respectively fixedly connected to a first filter screen 23 and a second filter screen 24, the aperture of the first filter screen 23 being larger than the aperture of the second filter screen 24, and the two mounting frames 22 being fixedly connected to the first filter screen 23 and the second filter screen 24, respectively. A connecting plate 26 is fixedly connected between the frames 21, and the filter component 2 is used to filter debris; a rotating component 3, the rotating component 3 includes a motor 31 arranged on the top of the filter cartridge 1 and a connecting rod 32 fixedly installed on the output end of the motor 31, a first bevel gear 33 is fixedly connected to the connecting rod 32, a second bevel gear 34 is meshingly connected to the first bevel gear 33, a rotating rod 35 is fixedly connected to the second bevel gear 34, and two mounting rods 39 are rotatably connected to the rotating rod 35, the mounting rod 39 is fixed to the top of the filter cartridge 1, and the rotating rod 35 is slidably connected to the first filter screen 23 and the second filter screen 24.

[0031] Among them, the feed pipe 11 is connected to the feces suction head, the first discharge pipe 12 is connected to the recovery tube and other debris collection devices, and the second discharge pipe 13 is connected to the feces storage tube of the feces suction truck. It should be noted that the filter component 2 is used to filter debris such as paper towels or packaging bags, and discharge them through the first discharge pipe 12, and the rotating component 3 is used to drive the first filter screen and the second filter screen to rotate, so as to clear the blocked first filter screen 23 or the second filter screen 24 through the action of centrifugal force.

[0032] In addition, the first filter screen 23 is arranged close to the feed pipe 11, the second filter screen 24 is arranged close to the second discharge pipe 13, and a plurality of spiral blades 38 for cutting off debris are fixedly connected to the rotating rod 35. Figure 2 and Figure 3 As shown, the filter cartridge 1 is divided into three parts by the first filter screen 23 and the second filter screen 24, wherein the part close to the feed pipe 11 is used for filtering debris, the part between the first filter screen 23 and the second filter screen 24 is used for crushing and cutting by the spiral blade 38, and the third part is used to discharge the filtered feces through the second discharge pipe 13.

[0033] Among them, a slider 211 is fixedly connected to the mounting frame 21, a slide groove 212 matching the size of the slider 211 is opened on the inner wall surface of the filter cylinder 1, a swivel 221 with a T-shaped cross-section is fixedly connected to the mounting frame 22, and a ring groove 222 matching the size of the swivel 221 is opened on the mounting frame 21.

[0034] It should be noted that the swivel ring 221 and the annular groove 222 are used to enable the mounting frame 22 to drive the first filter screen 23 or the second filter screen 24 to rotate on the mounting frame 21, and the slider 211 and the slide groove 212 are used to enable the mounting frame 21 to slide in the filter cartridge 1. Specifically, a hydraulic push rod 25 is fixedly connected to the bottom of one end of the filter cartridge 1 close to the second discharge pipe 13, and the protruding end of the hydraulic push rod 25 is fixedly connected to the mounting frame 21. The hydraulic push rod 25 is used to drive the mounting frame 21 to slide along the slide groove 212 when extending or retracting.

[0035] Furthermore, the rotational connection between the rotating rod 35 and the first filter 23 and the second filter 24 is fixedly connected to the limit plate 36, and correspondingly, the rotational connection between the first filter 23 and the second filter 24 and the rotating rod 35 is provided with a limit groove 361 adapted to the size of the limit plate 36, and both ends of the limit plate 36 are fixedly connected with a baffle 37. The first filter 23 and the second filter 24 can be a wire mesh, and the position of the rotational connection between the first filter 23 and the second filter 24 and the limit plate 36 on the rotating rod 35 should be thickened so that the first filter 23 and the second filter 24 can slide along the limit plate 36, and the baffle 37 is used to prevent the filter and the limit plate 36 from falling off.

[0036] It should be noted that, since the mounting frame 22 and the mounting frame 21 are rotatably connected, and the rotating rod 35 is fixed to the filter cartridge 1 through the mounting rod 39, when the first filter screen 23 and the second filter screen 24 slide back and forth with the mounting frame 21 under the action of the hydraulic push rod 25, the rotating rod 35 will not be affected, and repeated contraction and extension of the hydraulic push rod 25 can vibrate the filter screen to prevent the filter screen from being blocked. In addition, since the first filter screen 23 and the second filter screen 24 are both slidably connected to the rotating rod 35, the first filter screen 23 and the second filter screen 24 can both rotate when the rotating rod 35 rotates, so that the debris adsorbed on the filter screen can be separated by the action of centrifugal force to prevent the filter screen from being blocked.

[0037] In addition, the motor 31, hydraulic push rod 25 and two bevel gears should be installed with protective covers and other protective measures when they are set up to prevent feces from damaging the device and affecting the normal use of the equipment. The penetrating part of the connecting rod 32 and the filter cartridge 1 should be installed with sealing rings and other waterproof and leak-proof structures.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
