Problems solved by technology

At present, garbage bins are mostly used for automatic loading in collection operations, and garbage bins are used for unloading operations or built-in push shovels to discharge and unload materials. However, both methods need to open the sealed back door of the garbage bin at the same time, and kitchen waste will splash and cause secondary pollution.
[0003] The unloading operation of more advanced kitchen trucks also takes into account the way of sealed unloading: first, a manual valve is set near the lower end of the sealed rear door cover, but the valve position is not at the bottom of the vehicle, and manual operation of the valve is required The handle also has the problem of garbage splashing, which is easy to pollute the environment; in addition, due to the small diameter of the sewage discharge, the garbage is easily blocked, and the unloading efficiency is very low
Second, a discharge port is set at the bottom of the sealed back door, and the screw mechanism and the gate valve are used to automatically discharge the material by spinning. However, due to the structure of the screw machine, there is garbage that is easy to entangle and block, and the operation is hindered, which may easily cause the system to hold pressure and overload and malfunction. High rate, low unloading efficiency and other issues

Embodiment 1

[0042] Example 1: A seal unloading device for a shaftless screw machine

[0043] As introduced in the background technology, the unloading method of the kitchen truck in the prior art has garbage splashing, which causes secondary pollution; the hand valve has a small caliber, and the garbage is easy to block and inconvenient to operate; the existing shaft screw machine has garbage and is easy to entangle , the unloading resistance is large, the energy consumption is large, and the failure rate is high, which affects the unloading efficiency of the vehicle. In view of the above technical problems, this example designs the following loading and unloading devices.

[0044] like Figure 1-4As shown, the main structure of the shaftless screw machine sealing and unloading device in this case includes a screw machine housing 7, and the screw machine housing 7 is composed of a left-right symmetrical side sealing plate 14, a screw machine housing rear sealing plate 16, and a screw mac...

Embodiment 2

[0058] Example 2: A kitchen cart

[0059] Use the shaftless screw machine sealing unloading device of embodiment 1 to cooperate unloading, concrete structure is as follows:

[0060] as attached Figure 5 As shown, the kitchen cart in this example adopts a kitchen cart with a full pushing blade in the garbage bin, which can push and push the garbage horizontally and move backward. Its main structure includes:

[0061] Chassis 27, chassis 27 is the vehicle itself, including vehicle body frame and power structure.

[0062] The chassis is equipped with a universal top, which includes a dustbin 25 and a full push shovel 26, wherein the full push shovel 26 is used for pushing and unloading materials horizontally.

[0063] The afterbody of described dustbin 25 is provided with rear door 21, is provided with reliable sealing strip 22 on the end frame upper circle of rear door 21, and closely contacts (common structure) with the rear end frame of dustbin 25 by locking limit assembly...

Abstract

The invention discloses a shaftless screw conveyor sealed discharging device and a kitchen truck, and mainly relates to the field of special sanitation trucks. The shaftless screw conveyor sealed discharging device comprises a shaftless screw conveyor shell, wherein a discharging opening is formed in the bottom of the shaftless screw conveyor shell, a shaftless screw mechanism is rotatably arranged in the shaftless screw conveyor shell in a matched mode, the shaftless screw mechanism comprises end short shafts arranged at the two ends, the two end short shafts are provided with a rotating blade and a screw blade which are spliced, the rotating direction of the rotating blade is opposite to that of the screw blade, and the splicing position corresponds to the center of the discharging opening. The shaftless screw conveyor sealed discharging device has the beneficial effects that positioned, automatic and sealed discharging is achieved, the conveying capacity and operation efficiency of the device are improved, and the advancement and practicability of the kitchen truck are improved.

Description

technical field [0001] The invention relates to the field of sanitation special vehicles, in particular to a shaftless screw machine sealing unloading device and a kitchen vehicle. Background technique [0002] Kitchen trucks, also known as food waste collection and transport vehicles, are used to collect and transfer food waste generated by the catering industry, hotels, unit canteens, etc., and can also be used to collect and transfer food waste from residential quarters. Kitchen waste generally refers to leftovers, commonly known as swill. According to previous surveys conducted by domestic health websites, incomplete statistics show that in China, each person produces an average of about 100 grams of similar waste per day. Because food waste has special characteristics such as high oil content, high salt content, high spicy content in some areas, high permeability, and high pollution. Based on this, the sealing of food waste collection, transportation, and unloading oper...
