[0038] In a further preferred embodiment of the present application, a feeding hopper 12 for pouring excrement into the filter chamber is fixedly installed on one side of the box 1, a conveyor 13 for discharging the filtered excrement is installed on one side of the box 1, and the conveying belt of the conveyor 13 extends into the discharge chamber.

[0039] In this embodiment, during the operation of the device, the excrement to be treated is poured into the filter chamber in the box 1 through the feeding hopper 12. The driving mechanism drives the pressing plate 4 to move downward along the filter chamber, and the excrement in the filter chamber is extruded to realize solid-liquid separation. The extruded liquid is discharged into the discharge chamber through the filter plate 5, and the weighing assembly 6 at the bottom of the discharge chamber monitors the discharge amount in real time to determine whether the filter process is completed. When the filter process is completed, the moving support plate 3 is moved to make the solid excrement after filtering fall into the discharge chamber, and then the conveying belt of the conveyor 13 discharges the filtered excrement from the discharge chamber. The setting of the feeding hopper 12 facilitates the pouring operation of the excrement, and the operating personnel can directly add the excrement to the filter chamber through the feeding hopper 12, thereby improving the efficiency and convenience of feeding and reducing the complexity of manual operation. The installation of the conveyor 13 realizes the automatic discharge of the excrement after filtering. After the filter process is completed, the solid excrement falls into the discharge chamber, and the conveying belt of the conveyor 13 carries it out, without the need for manual cleaning, thereby greatly improving the discharge efficiency and reducing the labor intensity. At the same time, the health problems caused by manual operation are also avoided.

[0040] In a further preferred embodiment of the present application, an inclined plate 14 for guiding excrement is fixedly installed on one side of the discharge chamber, the inclined plate 14 is located above the conveying belt, one side of the box 1 is provided with a discharge port, the discharge port is matched with the conveyor 13, and a curtain 15 is installed in the discharge port.

[0041] In the embodiment, the setting of the inclined plate 14 plays a guiding role, so that the fecal cake after pressure filtration can smoothly slide along the inclined plate 14 to the conveying belt of the conveyor 13, avoiding the accumulation or uneven scattering of the fecal cake in the discharge cavity, ensuring the smoothness and stability of the discharge, and the blocking curtain 15 can effectively prevent the fecal cake from splashing out of the box 1 when being discharged onto the conveying belt, which not only maintains the cleanliness of the environment around the box 1, reduces the pollution of the feces to the environment, but also avoids the waste of the fecal cake and improves the utilization rate of resources.

[0042] In a further preferred embodiment of the present application, a set of moving mechanisms for driving a set of support plates 3 to open and close are arranged on the box 1, the moving mechanisms comprising: a connecting box 16 fixedly installed on one side of the box 1; a guide plate 17 fixedly installed in the connecting box 16, the guide plate 17 being in sliding connection with the support plate 3; a first rack 18 fixedly installed at the bottom of the support plate 3; a connecting gear 19 rotatably installed in the connecting box 16 and in meshing connection with the first rack 18; and a transmission mechanism arranged on one side of the box 1 for synchronously driving a set of connecting gears 19 to rotate relative to each other.

[0043] In the embodiment, when the transmission mechanism is started, a set of connecting gears 19 are driven to rotate relative to each other, and since the connecting gears 19 are in meshing connection with the first rack 18, the rotation of the connecting gears 19 drives the first rack 18 to move, thereby causing the support plate 3 to slide along the guide plate 17 and into the connecting box 16, realizing the opening and closing operation of the support plate 3. During the pressure filtration process, the support plate 3 is closed to separate the operation cavity from the pressure filtration cavity and the discharge cavity, and after the pressure filtration is completed, the support plate 3 is opened to allow the fecal cake after pressure filtration to fall into the discharge cavity and then slide along the inclined plate 14 to the conveying belt of the conveyor 13 for discharge;

[0044] By driving the connecting gears 19 to rotate through the transmission mechanism, the support plate 3 is stably slid along the guide plate 17 by using the transmission principle of the gear and rack, realizing precise opening and closing operation. This transmission mode has high precision and stability, which can ensure the accurate position of the support plate 3 during the opening and closing process, avoid deviation, and ensure the formation and separation effect of the pressure filtration cavity and the discharge cavity.

[0046] In the embodiment, when the feces are extruded by the pressing plate 4 in the filter chamber for solid-liquid separation, the extruded liquid tries to flow around under the action of pressure, and due to the close contact of the sealing gasket 20 with the top of the support plate 3 and the contact of the sealing strips 21 on the support plates 3 with each other, an effective sealing barrier is formed to prevent the liquid from flowing out from the gap between the support plate 3 and the gap between the support plates 3, thereby avoiding the liquid from flowing into the connecting box 16 and the discharge chamber.

[0047] In the further preferred embodiment of the present application, the box 1 is fixedly provided with a limiting cylinder 22 on one side, and the top end of the screw rod 9 is fixedly provided with a limiting rod 23, which is in sliding connection with the limiting cylinder 22 for guiding the up-and-down sliding movement of the screw rod 9.

[0048] In the embodiment, when the motor 11 drives the driving gear 10 to rotate and further drives the threaded cylinder 8 to rotate, the screw rod 9 will tend to move up and down due to the threaded cooperation with the threaded cylinder 8, at this time, the limiting rod 23 slides in the limiting cylinder 22, and the limiting cylinder 22 guides the limiting rod 23, so that the screw rod 9 can only slide up and down along the direction of the limiting cylinder 22, thereby driving the pressing plate 4 to stably move up and down along the filter chamber to extrude the feces in the filter chamber for solid-liquid separation.

[0049] In the further preferred embodiment of the present application, the transmission mechanism comprises: an engaging plate 24 fixedly installed at the bottom end of the limiting rod 23; a second rack 25 slidingly arranged at the bottom of the engaging plate 24; a group of differential gears 26 respectively arranged on the shaft of the connecting gear 19 and the box 1, a belt 27 being sleeved on the group of differential gears 26; a limiting wheel 43 rotatably installed on one side of the box 1 for limiting the belt 27; a group of first driven gears 28 respectively arranged on one side of the box 1 and the shaft of the differential gear 26 on the box 1, the group of first driven gears 28 being in engagement, and the first driven gear 28 on the differential gear 26 being in engagement with the second rack 25.

[0050] In the embodiment, when the feces is pressed by the pressing plate 4, the driving mechanism drives the pressing plate 4 to slide upwards, at this time, the screw rod 9 drives the limiting rod 23 to slide upwards along the limiting cylinder 22, the limiting rod 23 synchronously drives the connecting plate 24 and the second rack 25 to slide upwards, the second rack 25 contacts the first driven gear 28 on the differential gear 26 during the sliding process, and the second rack 25 drives the first driven gear 28 to rotate due to the meshing of the two, thereby driving the differential gear 26 to rotate, the differential gear 26 drives the other differential gear 26 to rotate through the belt 27, and the differential gear 26 is connected with the connecting gear 19 shaft, thereby driving the connecting gear 19 to rotate; the connecting gear 19 drives the first rack 18 to move, so that the supporting plate 3 slides along the guide plate 17 and slides into the connecting box 16, thereby realizing the opening operation of the supporting plate 3, and finally enabling the pressed and filtered feces to be discharged onto the conveying belt for subsequent discharging operation.

[0051] In the further preferred embodiment of the application, the second rack 25 is fixedly installed with a third rack 29 on one side, a second driven gear 30 is fixedly sleeved on the shaft of the first driven gear 28 on one side of the box body 1, the second driven gear 30 is meshed with the third rack 29, and a protective cover 31 for protecting the transmission mechanism is installed on one side of the box body 1.

[0052] In the embodiment, since the screw rod 9 continuously rises, after the second rack 25 slides away from the first driven gear 28, the third rack 29 rises to mesh with the second driven gear 30, the second driven gear 30 rotates through the third rack 29 and transmits the rotating force to a group of first driven gears 28, the group of first driven gears 28 relatively rotate, so that the differential gear 26 rotates in the opposite direction, thereby reversely rotating the connecting gear 19, and finally driving a group of supporting plates 3 to perform the closing operation, through the cooperation of the second rack 25 and the first driven gear 28 and the third rack 29 and the second driven gear 30, the supporting plate 3 is opened to discharge the material during the sliding process of the pressing plate 4, and the supporting plate 3 is automatically closed after the discharging is completed, thereby realizing the automatic circulation operation of the opening and closing of the supporting plate 3, without manual intervention, and improving the automation degree and working efficiency of the device.

[0053] In order to further improve the use effect of the device, in addition to the above-mentioned scheme, the present scheme also has the following embodiments:

[0054] In another embodiment of the present application, the box 1 is fixedly provided with a limiting block 32 on one side, the limiting block 32 is located on one side of the second rack 25, and the second rack 25 is fixedly provided with a limiting plate 33 on one side, the limiting plate 33 is oppositely arranged with the limiting block 32, the top of the connecting plate 24 is fixedly provided with a support 34, the support 34 is slidably provided with a connecting rod 35, the bottom of the connecting plate 24 is fixedly provided with a guide wheel 36, the bottom end of the connecting rod 35 is provided with a pull rope 37, the pull rope 37 penetrates through the connecting plate 24 and passes through the guide wheel 36, one end of the pull rope 37 is fixedly connected with the second rack 25, one side of the box 1 is fixedly provided with a clamping strip 38, the top end of the connecting rod 35 is fixedly provided with a U-shaped elastic steel plate 39, and the clamping groove of the U-shaped elastic steel plate 39 is clamped with the clamping strip 38.

[0055] In the embodiment, when the pressing plate 4 slides downward, the connecting plate 24 drives the connecting rod 35 to slide downward synchronously, because the clamping groove of the U-shaped elastic steel plate 39 is clamped with the clamping strip 38, the connecting rod 35 slides along the support 34 and pulls the pull rope 37, and the pull rope 37 further pulls the second rack 25 to move to one side, at this time, the limiting plate 33 located on the left side of the limiting block 32 moves to the right side of the limiting block 32, when the baffle of the connecting rod 35 contacts the support 34, the pull rope generates a large pulling force through the force of the continuous downward sliding of the connecting plate 24, so that the connecting rod 35 and the U-shaped elastic steel plate 39 slide downward, at this time, the U-shaped elastic steel plate 39 deforms and is separated from the clamping strip 38.

[0056] With the second rack 25 sliding downward synchronously with the connecting plate 24, the limiting plate 33 moves along the right side of the limiting block 32, and through the cooperation of the limiting plate 33 and the limiting block 32, the second rack 25 and the third rack 29 will not mesh with the first driven gear 28 and the second driven gear 30 when the pressing plate 4 moves downward, thereby avoiding the misoperation of the transmission mechanism in the process of the pressing plate 4 being pressed downward.

[0057] When the limiting plate 33 is away from the limiting block 32, the second rack 25 is automatically reset under the action of the reset spring 42, and the limiting plate 33 is reset to the left side of the limiting block 32, when the pressing plate 4 slides upward, because of the existence of the limiting block 32, the second rack 25 and the third rack 29 can smoothly mesh with the first driven gear 28 and the second driven gear 30, thereby making the transmission mechanism normally operate, realizing the opening and closing operations of the supporting plate 3, and when the U-shaped elastic steel plate 39 slides and contacts the clamping strip 38, the U-shaped elastic steel plate 39 deforms through the upward sliding force of the connecting rod 35 and is clamped into the clamping strip 38 again.

[0058] In another embodiment of the present invention, the bottom of the connecting plate 24 is provided with an installation groove, and a round rod 40 is fixedly installed in the installation groove. A slider 41 and a return spring 42 are slidably sleeved on the round rod 40. The two ends of the return spring 42 are fixedly connected to the installation groove and the slider 41 respectively. The slider 41 is fixedly connected to the second rack 25.

[0059] In this embodiment, when the pressure plate 4 slides down, the pull rope pulls the second rack 25 to move to one side. Since the second rack 25 is fixedly connected to the slider 41, the second rack 25 drives the slider 41 to slide along the round rod 40. During the sliding of the slider 41, the return spring 42 is compressed, and the return spring 42 stores elastic force. When the limiting plate 33 slides away from the limiting block 32, the return spring 42 releases the stored elastic force, pushes the slider 41 to slide in the opposite direction along the round rod 40, and then drives the second rack 25 and the limiting plate 33 to reset, so that the limiting plate 33 returns to the left side of the limiting block 32. When the pressure plate 4 slides up, the second rack 25 and the third rack 29 can mesh normally with the first driven gear 28 and the second driven gear 30 without obstruction, so as to drive the transmission mechanism to operate and realize the opening and closing of the support plate 3.

[0060] In summary, compared with related technologies, this device achieves efficient solid-liquid separation, uniform dehydration, and automated discharge of feces through precise pressure control by the weighing components and automatic opening and closing of the support plate by the transmission mechanism, effectively improving processing efficiency.

[0061] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
