Abstract

A self-propelled irrigation ditch cleaner for use by a single operator which includes a side-oriented conveyor to transport debris up and out of the ditch for the later collection.

Claims

1. Apparatus for removing debris from an irrigation ditch bounded by a bottom surface with side members extending upwardly therefrom said apparatus comprising:

(a) a frame including a drive wheel for movably contacting the bottom surface of an irrigation ditch;

(b) drive means mounted on said frame and coupled to said drive wheel for propelling said frame along the ditch;

(c) control means affixed to said frame for permitting operator control of said drive means;

(d) a forwardly-extending base member affixed to said frame, said base member having first and second opposing side edges and forward and rear edges;

(e) first and second upwardly-extending side members affixed to said first and second side edges respectively, said base and side members being dimensioned to fit within said ditch;

(f) a frame extension extending laterally from said frame in the direction of said second side member;

(g) transport means for moving the debris, said transport means being mounted on said frame and frame extension spaced adjacent to said second side member and including;

i. first and second sprockets affixed to said frame and said frame extension respectively, said first sprocket being located on said frame proximate to the base member, and

ii. a chain containing spaced flights and encircling said first and second sprockets; and

(h) coupling means connected to said drive means and including clutch means for controlling movement of said chain for imparting movement to the transport means whereby debris located on said base member is urged by the flights of said transport means upwardly along said second side member for removal from the ditch.

2. Apparatus in accordance with claim 1 wherein said second side member is longer than said first side member.

3. Apparatus in accordance with claim 2 wherein said drive means is mounted on said frame proximate to said first side member.

4. Apparatus in accordance with claim 3 further comprising a rear support plate affixed to the rear edge of the base member and to the side members.

5. Apparatus in accordance with claim 4 further comprising a forward channel guide extending upwardly on the second side member and mounted thereon forward of said transport means.

6. Apparatus in accordance with claim 5 wherein the forward edge of said base member is longer than the rear edge thereon.

7. Apparatus in accordance with claim 6 wherein the forward edge of said base member is downwardly inclined.

8. Apparatus in accordance with claim 7 further comprising wedge-shaped support members affixed to said frame and extending beneath said base member.

9. Apparatus in accordance with claim 8 further comprising wedge-shaped support members affixed to said side members and extending forwardly to provide outwardly angled side members.

10. Apparatus in accordance with claim 9 further comprising a removable leading edge member affixed to the forward edge of said base member.

11. Apparatus in accordance with claim 9 further comprising a removable leading edge member affixed to the forward edge of said side members.

12. Apparatus in accordance with claim 3 further comprising a forward channel guide extending upwardly on the second side member and mounted thereon forward of said transport means.

13. Apparatus in accordance with claim 12 further comprising a rear channel guide extending upwardly on the second side member and mounted thereon rearward of said transport means.

14. Apparatus in accordance with claim 1 wherein said flights are affixed to the chain and extended outwardly therefrom, said flights being spaced adjacent to the second side member to urge debris therealong.

15. Apparatus in accordance with claim 14 wherein said flights each comprise a forward lip and rearward extension, the rearward extension being dimensioned to contact the lip of the next flight affixed to the chain.
