Abstract

A feed mixer for mixing material. The feed mixer includes a tub that defines a tub interior. A rotatable screw assembly is located in the tub interior. A conveyor assembly is pivotably located along an outer surface of the tub at a discharge opening. The screw assembly moves material towards the conveyor assembly as the screw assembly rotates. The conveyor assembly includes a conveyor and a positioning system configured to move the conveyor between a conveying state, a stowed state, and a maintenance state.

First claim

What is claimed is:

1 . A feed mixer for mixing material, the feed mixer comprising:
a tub comprising a bottom and at least one sidewall, the at least one sidewall comprising an outer surface and an inner surface, a discharge opening located in the at least one sidewall, the inner surface and the bottom defining a tub interior; a screw assembly located in the tub interior, the screw assembly being rotatable; a conveyor assembly pivotably located along the outer surface at the discharge opening, wherein the screw assembly moves material towards the conveyor assembly as the screw assembly rotates, the conveyor assembly comprising:
a conveyor mounting bracket pivotably mounted to the tub;
a linkage pivotally mounted to the tub;
a conveyor pivotally mounted to the conveyor mounting bracket and pivotally mounted to the linkage; and
an actuator for moving the conveyor between a stowed position and a maintenance position.

2 . The feed mixer of claim 1 , wherein the linkage is adjustable between a locked state and an unlocked state.

3 . The feed mixer of claim 2 , wherein when the linkage is in the unlocked state the actuator is able to move the conveyor between the stowed position and a conveying position.

4 . The feed mixer of claim 3 , wherein the conveyor is pivotally mounted to the conveyor mounting bracket at a first axis, the conveyor rotating about the first axis to move between the stowed position and the conveying position.

5 . The feed mixer of claim 1 , wherein the conveyor is pivotally mounted to the conveyor mounting bracket at a first axis, the conveyor is pivotally mounted to the linkage at a second axis, the linkage is pivotally mounted to the tub at a third axis, and the conveyor mounting bracket is pivotally mounted to the tub at a fourth axis, wherein the conveyor rotates about the third axis and the fourth axis to move into the maintenance position from the stowed position.

6 . The feed mixer of claim 5 , wherein at least one of the third axis and the fourth axis is located above the first axis.

7 . The feed mixer of claim 5 , wherein the linkage is adjustable between a locked state and an unlocked state, and when the linkage is in the locked state the actuator is able to move the conveyor into the maintenance position.

8 . The feed mixer of claim 3 , wherein the conveyor mounting bracket is secured to the tub in the conveying position.

9 . The feed mixer of claim 8 , wherein the conveyor mounting bracket is secured to the tub by threaded fasteners in the conveying position.

10 . The feed mixer of claim 1 , wherein when the conveyor is in the maintenance position, the conveyor is above a plane defined by the bottom of the tub.

11 . The feed mixer of claim 1 , wherein the conveyor assembly is located above a wheel assembly of the feed mixer.

12 . The feed mixer of claim 11 , wherein the maintenance position permits access to the wheel assembly.

13 . A feed mixer for mixing material, the feed mixer comprising:
a tub comprising a bottom and at least one sidewall, the at least one sidewall comprising an outer surface and an inner surface, a discharge opening located in the at least one sidewall, the inner surface and the bottom defining a tub interior; a screw assembly located in the tub interior, the screw assembly being rotatable; a conveyor assembly pivotably located along the outer surface at the discharge opening, wherein the screw assembly moves material towards the conveyor assembly as the screw assembly rotates, the conveyor assembly comprising:
a conveyor; and
a positioning system configured to rotate the conveyor between a stowed position, a conveying position, and a maintenance position, wherein the positioning system includes:
a conveyor mounting bracket, wherein the conveyor mounting bracket is pivotably mounted to the tub and the conveyor; and
an actuator for moving the conveyor between the stowed position, the conveying position, and the maintenance position,
wherein the actuator is able to move the conveyor between the stowed position and the conveying position by rotating the conveyor, and
wherein the actuator is able to move the conveyor into the maintenance position by rotating the conveyor about two different axes.

14 . The feed mixer of claim 13 , wherein the conveyor assembly further includes:
a linkage adjustable between a locked state and an unlocked state, wherein when the linkage is in the unlocked state the actuator is able to move the conveyor between the stowed position and the conveying position; and wherein when the linkage is in the locked state the actuator is able to move the conveyor into the maintenance position by rotating the conveyor.

15 . The feed mixer of claim 14 , wherein the linkage comprises an outer member and an inner member, wherein when the linkage is in the unlocked state, the inner member slides within the outer member, and wherein when the linkage is in the locked state, the inner member is not slidable within the outer member.

16 . The feed mixer of claim 13 , wherein the maintenance position rotates the conveyor such that the conveyor is moved above a plane defined by the bottom of the tub.

17 . The feed mixer of claim 13 , wherein the conveyor assembly is located above a wheel assembly of the feed mixer.

18 . The feed mixer of claim 14 , wherein the maintenance position permits access to a wheel assembly.

19 . A feed mixer for mixing material, the feed mixer comprising:
a tub comprising a bottom and at least one sidewall, the at least one sidewall comprising an outer surface and an inner surface, a discharge opening located in the at least one sidewall, the inner surface and the bottom defining a tub interior; a screw assembly located in the tub interior, the screw assembly being rotatable; a conveyor assembly pivotably located along the outer surface at the discharge opening, wherein the screw assembly moves material towards the conveyor assembly as the screw assembly rotates, the conveyor assembly comprising:
a conveyor; and
a positioning system configured to rotate the conveyor between a conveying state, a stowed state, and a maintenance state.
