After the excrement falls into the excrement receiving bag 174, the pneumatic finger 183 works, the pneumatic finger 183 drives the two buckling pressing blocks 184 to be close to each other and clamp the excrement receiving bag 174, so that the hot melt adhesive tapes 181 on the inner walls of the two sides of the excrement receiving bag 174 are attached to each other, then the heating wire 182 is powered on, the heating wire 182 is powered on to generate heat, the buckling pressing blocks 184 are heat conducting blocks, the heat can be conducted to the hot melt adhesive tapes 181, the hot melt adhesive tapes 181 have certain mobility after being heated to a certain temperature, at the moment, the two hot melt adhesive tapes 181 are fused with each other, the heating wire 182 stops supplying power to the heating wire 182 after heating for a period of time, at the moment, the two mutually fused hot melt adhesive tapes 181 are solidified and integrated, finally, the sealing of the excrement receiving bag 174 is realized, and the phenomenon that the peculiar smell in the.
Referring to fig. 9 and 10, since the stool falls into the bottom of the stool receiving bag 174 and the two fastening pieces 184 approach each other, only the fixed position of the stool receiving bag 174 is sealed at a time, so that the stool can be collected by the stool receiving bag 174 only once. In this embodiment, the length direction of the hot melt adhesive tape 181 is the same as the height direction of the feces collection bag 174, the inner sidewall of the feces collection basket 173 has an adjustment groove 19 along the height direction thereof, and the adjustment groove 19 is provided with a second electric cylinder 20 for driving the pneumatic finger 183 to ascend and descend.
The second electric cylinder 20 is utilized to adjust the pneumatic finger 183 to a proper position, and the length direction of the hot melt adhesive tape 181 is consistent with the height direction of the excrement receiving bag 174, so that the proper height of the excrement receiving bag 174 is sealed, the frequency of collecting excrement of the excrement receiving bag 174 is increased, and resources are saved.
Referring to fig. 5 and 10, a supporting plate 26 for supporting the feces collection bag 174 is slidably disposed in the feces collection basket 173 along the height direction thereof, a spring 27 is disposed on the lower surface of the supporting plate 26, one end of the spring 27 away from the supporting plate 26 is connected to the inner bottom wall of the feces collection basket 173, the extending and contracting direction of the spring 27 is the same as the height direction of the feces collection basket 173, and as the amount of feces collected in the feces collection bag 174 increases, the spring 27 is compressed, and at this time, the supporting plate 26 moves downward.
The lower surface of the supporting plate 26 is provided with a distance sensor 28, the distance sensor 28 is electrically connected with the second motor 25, the distance sensor 28 adopts a wireless laser ranging sensor, the distance between the lower surface of the supporting plate 26 and the inner bottom wall of the excrement collection basket 173 is detected by the distance sensor 28 in real time, and the detected distance value is transmitted to the PLC control circuit for calculation and analysis in real time.
When the feces in the feces collection bag 174 is full, the support plate 26 is located at the bottom of the feces collection basket 173, the distance between the support plate 26 and the inner bottom wall of the feces collection basket 173 is set as an initial value, the initial value is stored in the PLC control circuit, and when the detected distance reaches the set initial value, the second motor 25 operates to drive the screw 23 to rotate, so as to drive the two feces collection baskets 173 to move synchronously, and further move the feces collection bag 174 full of feces to one side of the material guide plate 171, and at this time, another empty feces collection bag 174 can be placed below the material guide plate 171 for receiving feces.
The implementation principle of this application embodiment intelligence cat lavatory of weighing does: after the cat had gone up the lavatory, the weight in the cat litter box 1 becomes heavy, utilize electronic scale 61 to weigh in real time the cat litter in the cat litter box 1, and convey the weight signal who weighs to PLC central processing unit 62, the weight signal who weighs processes the back through PLC central processing unit 62, send to remote control terminal through wireless communication module 63, remote control terminal is the cell-phone, in order to remind people in time to clear up cat litter box 1, avoid the excrement and urine in the cat litter box 1 to pile up and influence indoor environment sanitation.
When people go out and can not clean the excrement in the cat litter box 1 in time, the PLC central processing unit 62 starts the first motor 153 to drive the first fluted disc 151 to rotate, drive the serrated ring 152 to rotate and further drive the cleaning cylinder 7 to rotate, and then the sand shovel 14 can screen the cat litter in the cat litter box 1 along with the rotation of the cleaning cylinder 7; after screening excrement and urine, start first electric jar 163, drive rack 162 and go up and down, drive first fluted disc 151 and rotate, and then can be with sand shovel 14 by cat sand box 1 internal rotation to clean room 12 in, and then excrement and urine in the sand shovel 14 drops to on the stock guide 171, can be with in the leading-in excrement and urine bag 174 of receiving through stock guide 171.
Then the second electric cylinder 20 is started, the pneumatic clamping finger 183 is driven to ascend and descend to a proper height, the two buckling pressing blocks 184 are driven to be close to each other through the pneumatic clamping finger 183, the hot melt adhesive tapes 181 on the inner walls of the two sides of the excrement collecting bag 174 are attached to each other, at the moment, the heating wire 182 is electrified to generate heat, the heat can be conducted to the hot melt adhesive tapes 181 through the buckling pressing blocks 184, then the hot melt adhesive tapes 181 have certain fluidity after being heated to a certain temperature, at the moment, the hot melt adhesive tapes 181 on the inner walls of the two sides of the excrement collecting bag 174 are mutually fused, when the heating wire 182 generates heat for a period of time, the power supply to the heating wire 182 is stopped, at the moment, the two mutually fused hot melt adhesive tapes 181 are solidified and integrated, finally, the sealing of the excrement collecting bag 174 is realized, and the.
As the stool in the stool collection bag 174 increases, the spring 27 is compressed, the support plate 26 moves downward in the stool collection basket 173, the distance between the support plate 26 and the bottom wall of the stool collection basket 173 is detected by the distance sensor 28 in real time, the detected distance value is transmitted to the PLC central processor 62, and if the distance value reaches a set value, the PLC central processor 62 sends a start command to the second motor 25 when the stool collection bag 174 is full of stools.
The second motor 25 is started to drive the screw rod 23 to rotate, and the sliding chute 22 plays a role in guiding and limiting the sliding of the sliding blocks 24, so that the two sliding blocks 24 are driven to synchronously slide in the sliding chute 22, and then the two excrement collecting baskets 173 synchronously slide, so that the excrement collecting bag 174 filled with excrement can be moved to one side of the material guide plate 171, and meanwhile, the bag opening of the empty excrement collecting bag 174 is aligned to the lower end of the material guide plate 171, and the continuous collection is facilitated; by adopting the above mode, realized clearing up and collecting the excrement and urine in the cat sand box 1 automatically, can avoid influencing the indoor air quality, prevent that people from not being in the time, can not in time clear up cat sand box convenient and practical.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
