Technical Field

The invention relates to the field of design of intelligent control mechanisms of environmental sanitation equipment, in particular to an automatic discharging mechanism of a kitchen vehicle, which supports voice control.

Background

In recent years, with the progress of the consumption concept of people, the catering industry has the trend of rapid development, which brings benefits to the economic development of entities and simultaneously causes a plurality of social problems, such as the problem of centralized treatment of a large amount of kitchen waste, because the kitchen waste has the characteristics of large fluidity, complex components, large smell and the like, catering employees often do not change to carry out self-treatment, the kitchen waste vehicle is used for collecting and transporting kitchen waste accumulated on the same day at catering sites in the district and sending the kitchen waste to a centralized treatment site for treatment, but the traditional kitchen vehicle is operated by an operator through a knob switch or a multi-way valve beside a box body, the operation mode can easily cause that a large amount of kitchen waste splashes to the body of an operator when being discharged, and the trouble of the next feeding process of the material belt due to the fact that the push shovel is not actively reset after the material discharge is finished can be avoided.

Disclosure of Invention

In conclusion, the automatic material discharging mechanism supporting voice control for the kitchen vehicle effectively solves a series of problems of manual operation, and provides a new idea for intelligent control of material discharging operation of the kitchen vehicle.

The specific implementation mode of the invention is as follows: the utility model provides a support speech control's meal kitchen car automatic discharge mechanism which characterized in that: the device comprises a push shovel and a push shovel oil cylinder for driving the push shovel to move forward and backward, wherein an inductive proximity switch is arranged at the foremost end of the backward movement direction of the push shovel, and when the device is delayed to reset and return, the device reaches a detection position of the proximity switch to indicate that the device returns to the position; the rear door assembly is driven by a rear door oil cylinder and integrates a screw machine, a hydraulic motor, a gate plate and a gate plate oil cylinder, the hydraulic motor drives the screw machine to rotate and break materials, and the gate plate oil cylinder drives the gate plate to open and close to discharge dry materials; the locking device consists of a locking pin, a locking oil cylinder and a locking proximity switch, the locking oil cylinder drives the locking pin to move up and down, and the locking proximity switch detects the position of the locking pin; the voice recognition module is arranged outside the box body, so that voice instruction information can be clearly received, and the embedded controller and the data conversion module are arranged in the cab and used for processing the instruction information and sending out an execution signal.

The utility model provides a support speech control's meal kitchen car automatic discharge mechanism which characterized in that includes following specific operation:

1) a parameter adjustment interface is developed on the embedded controller, and the time for opening the back door, the time for closing the back door, the time for pushing the blade, the time for retracting the blade, the time for closing the lock, the time for opening the gate plate, and the time for closing the gate plate can be set.

2) All the above adjustment times are bottom layer times, and even when a proximity switch detection signal exists, the proximity switch signal is preferably used as a main time.

3) When an operator sends a voice command of 'rear door material discharge', the locking pin moves upwards to be disconnected with the rear door assembly, the locking proximity switch detection signal disappears at the moment, the system executes rear door opening when the proximity switch signal disappears and the locking opening time is reached, the rear door oil cylinder drives the rear door to open, and when the set rear door opening time is reached, the push shovel is pushed out until the push shovel is pushed out for the time, so that material discharge is completed.

4) After the kitchen waste is completely pushed out, the push shovel is delayed for a moment, the push shovel is executed to return to the position where the push shovel proximity switch is detected, the push shovel returns to be executed, the back door is closed until the back door is closed, the locking proximity switch detects a signal, and resetting after discharging is completed.

5) When the operating personnel sent "flashboard row material" voice command, at first the execution pushes away the shovel and releases, and here hydraulic motor drive screw is rotatory simultaneously, and flashboard hydro-cylinder drive flashboard after the time delay is opened, and under the screw-driver effect, destroyed kitchen garbage liquid permeates the sewage incasement, and the drier residue can be discharged by the flashboard mouth.

6) When an operator sends a 'discharging end' voice command, the screw conveyor is stopped, the flashboard is closed, and the push shovel returns to the position detected by the push shovel proximity switch.

The invention realizes the control of the execution mechanism by the embedded controller through programming, applies the voice recognition module to be fused with an embedded system through secondary development, replaces the traditional input mode of a knob and a key, utilizes the voice instruction information established in advance, can enable the whole discharging mechanism to complete automatic discharging and resetting operations only by a simple sentence of instructions, can close all outputs by a stop instruction when the execution mechanism executes any action, has more advantages in response failure of subjective stop in emergency, can input a control command when the execution mechanism is far away from a box body, and can select a favorable observation station, thereby ensuring the personal safety and improving the operation efficiency and simultaneously enhancing the user operation experience and the product intelligence.
