Abstract

An improved means for dispensing a substantially even flow of semi-liquid material such as, concrete, into remote areas includes the use of an auger assembly mounted within a bucket of a construction machine. The auger assembly has a tubular housing with sealed end portions and an intermediate portion. The intermediate portion has a receiving passage defined therein. An auger is mounted within the tubular housing and has a blade portion which is rotatable in either a first or second direction by power supplied through a bi-directional motor. The semi-liquid material is poured into the bucket and enters the auger only through the receiving passage. The direction of rotation is chosen by an operator so that the material is conveyed along a rotational axis toward either a first or second opening, respectively, adjacent a remote area. The semi-liquid material flows substantially evenly through either the first or second openings to fill the remote area uniformly.

Claims

1. A bucket assembly for use with a construction machine having a pair of articulated arms, comprising:

a bucket pivotably attachable to an end of each of the pair of articulated arms, the bucket having a front wall and a rear wall spaced from the front wall to define an inner chamber therebetween for receiving material with the inner chamber defining first and second openings therethrough,

an auger assembly secured within the inner chamber of the bucket, the auger assembly having a tubular housing with first and second substantially sealed end portions encapsulating respectively the first and second openings in the bucket and an intermediate portion defining a receiving passage in communication with the first and second end portions and a rotatable auger supported within the tubular housing at the first and second end portions;

means mounted within the bucket for transmitting power to the rotatable auger; and

the rotatable auger having a blade portion being operatively associated with the transmitting means for rotation in a first direction to move the material toward the first end portion and for rotation in a second direction to move the material toward the second end portion.

2. A bucket assembly for use with a construction machine as set forth in claim 1, wherein the blade portion has a outer edge in contact with an inner surface of the tubular housing.

3. A bucket assembly for use with a construction machine as set forth in claim 2, wherein the outer edge of the blade portion is made from a non-metallic material.

4. A bucket assembly for use with a construction machine as set forth in claim 3, wherein the non-metallic material is rubber.

5. A method for dispensing a semi-liquid material from a bucket of a construction machine to an adjacent area remote from the bucket, comprising the steps of:

mounting an auger assembly into an inner chamber of the bucket, the auger assembly having a tubular housing with first and second substantially sealed end portions encapsulating respectively first and second openings in the bucket and an intermediate portion defining a receiving passage in communication with the first and second end portions and a rotatable auger having a blade portion supported within the tubular housing at the first and second end portions;

pouring a semi-liquid material into the inner chamber of the bucket so that the material enters the tubular housing at the receiving passage in the intermediate portion;

transmitting power to the rotatable auger through a transmitting means for rotating the blade portion of the auger in a specific direction for conveying the material longitudinally along a rotational axis of the auger from the receiving passage at the intermediate portion toward one of either the first or second end portions; and

dispensing a substantially even flow of material into the adjacent area from the one of either the first and second end portions through the respective first and second openings in the bucket.

6. The method of dispensing a semi-liquid material from a bucket as set forth in claim 5, wherein the step of dispensing a substantially even flow of material includes the step of:

attaching a rubber wiper at an outer portion of the blade portion for contact with an inner surface of the tubular housing during rotation for preventing excess material from dispensing through the first and second openings.

7. A bucket assembly, comprising:

a bucket having a front wall and a rear wall spaced from the front wall to define an inner chamber therebetween for receiving material with the inner chamber defining first and second openings therethrough, an auger assembly secured within the inner chamber of the bucket, the auger assembly having a tubular housing with first and second substantially sealed end portions encapsulating respectively the first and second openings in the bucket and an intermediate portion defining a receiving passage in communication with the first and second end portions and a rotatable auger supported within the tubular housing at the first and second end portions;

means mounted within the bucket for transmitting power to the rotatable auger; and

the rotatable auger having a blade portion being operatively associated with the transmitting means for rotation in a first direction to move the material toward the first end portion and for rotation in a second direction to move the material toward the second end portion.
