Abstract
The invention relates to a garbage compacting box garbage scattering-free hopper. The hopper is made of steel plates of 3mm and is light in weight. Flanging steel channels are welded to the back surface of the hopper to enhance the stiffness. Each flanging steel channel is one side less than a rectangular tube, and the weight of each flanging steel channel is less than that of the rectangular tube. The whole hopper is light in weight. The use amount of steel plates is reduced. The overturning force for the hopper is small. Energy is saved. When the hopper is overturned by 180 degrees upside down to dump garbage, the whole hopper is embedded among three baffles of a compacting box without outward open surfaces. Garbage slides down along an inclined guide plate and inclined baffles on the two sides without dust generation and garbage flying, so that the working environment is clean and free of secondary pollution. The hopper is provided with a trigger control circuit for intelligently adjusting the inclination angle of the inclined guide plate, and the adjusted angle can be displayed in real time.

Technical field
The present invention relates to the technical field of rubbish movement compression box manufacture, is related to a kind of garbage compression box rubbish without shedding material
Bucket.
Background technology
With going deep into for reform and opening-up, national economy is growing, and requirement of the people to living environment is also improved constantly, and wishes
Prestige is lived in health, clean and tidy fine environment.Therefore, impact when rubbish is toppled over, transports to surrounding enviroment, it is proposed that higher
Requirement.Garbage transporting develop into from open type it is closed, in order to improve transport efficacy, often garbage-compressing in steel-structure box
Hopper is poured in transport in sub, rubbish into, and hopper overturns 180 ° and pours in garbage compression box, rubbish from hopper pour into compression box when
Carve, rubbish comes down in torrents from hopper, without in the entrance cabin being oriented to, the lighter rubbish in part falls from above and can fly poplar and generation
Dust, working environment of making dirty, causes secondary pollution.Therefore, a kind of garbage compression box rubbish for breaking through above obstacle is needed badly without throwing
Spreading bucket.
The content of the invention
In view of this, the present invention provides a kind of solution or the garbage compression box rubbish that solves the above problems of part without shedding material
Bucket.
To reach the effect of above-mentioned technical proposal, the technical scheme is that：A kind of garbage compression box rubbish is without shedding
Hopper, garbage compression box rubbish are manufactured using 3mm steel plates without hopper is shed, and there is inclination stock guide at the back side, enables rubbish to take advantage of a situation
Slide and do not produce dust and rubbish flies upward；
Garbage compression box rubbish without shed in hopper be embedded in trigger control circuit with control incline stock guide inclination angle
Degree, to realize the adjustment at any time to which；Trigger control circuit can be divided mainly into control module, automatically controlled drive part and power supply unit
Point；
