Automatic pet feeding machine

Abstract

The invention belongs to animal feeding devices and provides an automatic pet feeding machine which is intelligently controlled by adopting a PLC (Programmable Logic Controller) circuit. According to the automatic pet feeding machine, a PLC intelligent control system is used, control parameters are input through a control panel so as to set feeding starting time, feeding ending time and a feeding quantity, and finally, a PLC controller drives a stepping motor and a feed box valve to complete the actions of feeding and cleaning according to settings, so that the needs of pet feeding during business trip or long-term leaving are met; a motor is driven to rotate through a PLC driver so as to clean a feed box, and thus, diseases cannot be caused due to excessive food accumulation or pollution while a pet can obtain food of a set quantity; the feeding and residual food residue removal can be carried out in a timed manner according to user or system settings.

Description

Technical field:

[0001] The invention belongs to an animal feeding device, and relates to an automatic pet feeding machine controlled intelligently by a PLC circuit. Background technique:

[0002] Pets, as people's partners, are being kept more and more widely by families with the improvement of people's living standards. But it is precisely because of the accelerated pace of people's lives that people often have no time to devote too much energy to taking care of pets, such as when they are busy at work, when they need to work overtime or on business trips, and when they want to go home to visit relatives. It is very inconvenient to leave pets to others to take care of. Traditional pet feeding machines are divided into three types: variable feeding machines, timing feeding machines and intelligent feeding machines. The variable feeding machine uses the principle of gravity, how much food the pet eats, the amount of food will flow out, and the pet will often pollute the foo...

Examples

Embodiment 1

[0016] Such as Figure 1-3 As shown, an automatic pet feeding machine includes a stepping motor 3, a small gear 4, a large gear 5, a rocker 6, a connecting rod 7, a food box cover 11, a food box 12, and a food box valve 13; it also includes a control panel 1. PLC controller 2. Cleaning scraper 8. Slider bottom plate 9. Chute 10. Dirt tray 14. The control panel 1 is connected with the PLC controller 2, and the input command is transmitted to the PLC controller 2 through the control panel 1; the PLC controller 2 is connected with the stepping motor 3. Food box valve 13 is connected with PLC controller 2 simultaneously. Rocking bar 6, connecting rod 7, slider bottom plate 9, and chute 10 form a crank slider mechanism and are fixed inside the pet feeding machine. Wherein the small gear 4 is connected with the stepping motor 3, and rotates with the rotation of the stepping motor; the rocking bar 6 is connected with the large gear 5, and the rocking bar 6 swings with the rotation ...

[0025] In order to facilitate the disassembly of the dirt tray 14, the dirt tray 14 can be made into a strip-shaped protrusion on one side and a through hole on the other side; the corresponding side of the slider bottom plate 9 is a groove, and the other side is a groove. Threaded hole. Its fastening method is that the protrusion on one side of the dirt tray 14 is snapped into the groove on one side of the slider bottom plate 9, and the other side is fastened with bolts. . Others are with embodiment 1.
