DESCRIPTION
THE FIELD OF INVENTION:
The present invention pertains to a measurable collection container for the
construction waste.
THE BACKGROUND OF THIS INVENTION
The conventional way to load the construction waste now is to put the waste
into the trash
container and ship it by the trash trucks to the transfer station. Usually it
is charged based on the
full container of different existing size, which is unfair for the project
whose garbage amount is
less than one container because the minimum quantity of loading requested for
one time has to be
one container. Besides, the trash container currently used is very heavy and
it needs to be shipped
by special trash truck, which lacks of flexibility of shipping the garbage for
the smaller
construction company or decorating company.
In order to solve the above problem, a new type of measurable collection
container for the
construction waste is designed in this patent. It is not the construction
trash bin as commonly
used, but a container which collects the construction waste from the trash bin
into it and weighs
before being consolidated into the trailer of the truck. Therefore, the
construction company or the
decorating company can call the trash truck company to come any time. The
construction waste
is to be weighed and paid on the spot of construction site before being
shipped, providing great
convenience of delivering the construction waste for the construction company
or decorating
company.
CONTENT
I. According to the claims, this measurable collection container for
construction waste is made
of metal. Most of the nonmetal material can not sustain the pounding effect
caused by the
construction waste because it is bulky and heavy. Other hard material like
reinforced glass
can also be used but the cost is pretty high. So the material of metal is
recommended for this
collection container.
2. The main characteristic for this measurable collection container lies in
that it has a digital
weight sensor (figure 1-1) and a weight indicator (figure 1-2). The weight
sensor is installed

at the bottom of the collection container and the weight indicator screen is
set in one side of
the collection container which can be easily seen. When the waste is put into
the collection
container, the weight data is displayed on the digital screen through the
sensor.
3. There is one pickup sleeve set on each side of this measurable collection
container, (figure
1-3), the purpose of which is: when the collection container with garbage is
ready to be
delivered, the front forks of the trash truck can be extended to hold the pick
up sleeves, lifting
the collection container up and dump the garbage into the trailer of the trash
truck (figure 2).
The pickup sleeves are fixed onto the two sides of the collection container by
the rivets.
4. For the convenience of loading the bulky and heavy garbage into the
collection container with
little effort, a movable door is designed in one side of the collection
container through the
door spindle (figure3) and the other side can be opened and closed with a bolt
to fix the door
tightly and safely. (figure 4)
5. There are four wheels on the bottom of this measurable collection container
(figure 1-4), the
purpose of which facilitates the moving of it; there are 4 base plates
designed respectively at
the corners of the bottom of the collection container (figure5-1); On each of
the base plate is a
hole (figure 5-2); the stand of the wheel comprises 2 parts, a thick one and a
thinner one
(figure 5-3 and figure 5-4); the way of the thinner part to be inserted into
the holes in the base
plate (figure 5-5); the thick part is stuck into the bottom of the collection
container and the
weight is transferred to the four wheels (figure 5-6).
6. A weight sensor is designed at the bottom of the measurable collection
container (Figure 6).
The weight sensor comprises the base plate (Figure 6-1), the holes on the base
plate, the
connection stand for the base plate and the spring (Figure 6-2), the sensor
(Figure 6-3) and
the stand of the wheel (Figure6-4). The weight sensor is connected with the
digital weight
indicator on the side of the measurable collection container, transferring the
digital weight
data of the garbage to the screen of the indicator.

Figure 1: The front and lateral view of the measurable collection container
for the construction
waste, and it is made of metal, at the bottom of which is the weight sensor
(Figure 1-1)
and 4 wheels (Figure 1-4). On the 2 sides of the collection containers are the
pickup
sleeves fixed by the rivets. (Figure 1-3)

Figure 2: It shows the way of working between the measurable collection
container and the trailer
of the trash truck. The front forks of the trash truck (Figure 2-1) is
extended to hold the
pickup sleeves (Figure 2-2) which is fixed on the two sides of the collection
container
already weighted. The pickup sleeves lift the measurable collection container
with
garbage in it and empty it into the trailer of the trash truck. The trailer of
the trash truck
is now commonly used and is not included in the patent applied.
Figure 3: and Figure 4 shows that there is a movable door on one side of this
measurable
collection container which helps to move the bulky garbage more easily. One
side of
the door can be opened and the other side is connected through the door
spindle (Figure
3). The door can be closed and fixed with a bolt (Figure 4). Two bolts are
specially
designed in order to close the door tightly.
Figure 5: It shows the design of the bottom of this measurable collection
container. Figure 5-1 is
the base plate for the wheels; Figure 5-2 is the hole in the base plate;
Figure 5-3 is the
thinner stand; Figure 5-4 is the thick stand, Figure 5-5 shows the way of the
thinner
stand inserting into the hole of the base plate; Figure 6 are the wheels.
Figure 6: It shows the design of the weight sensor. Figure 6-1 is the base
plate for the weight
sensor and the base plate contacts the ground. Figure 6-2 is the elastic
spring between
the sensor and the base plate, and the elastic spring will ensure the base
plate can
contact the ground. When the garbage inside is filled in, the collection
container will
sink, leading to the contact of the weight sensor with the base plate, then
the weight
data will be displayed on the screen. Figure 7 shows the details. Figure 6-3
shows the
position of the weight sensor and the weight data is shown on the screen
through the
sensor.
Application:
When garbage is loaded into the collection container, the container will sink
owing to the weight
of the garbage, giving the pressure to the weight sensor. Then the spring is
compressed, the base
plate connects the weight sensor which calculates the weight and the weight
data will be
displayed on the indicator. It is charged based on the weight data. The front
forks of the trash
truck lift the collection container by holding the pickup sleeves and then
empty the garbage into
the trailer of the truck. After being emptied, the collection container can be
prepared for next use.
