Abstract

A rectangular baler including a chassis; a compacting plunger supported on the chassis for advancing crop material; and a bale chamber between the compacting plunger and the back end. The chassis is provided with a first and second sidewall extending from the front end in the direction of the back end. There is further provided a pull rod connecting the first sidewall and the second sidewall, at a location between the plunger and the front end. The pull rod has a first part and a second end part extending freely through a first hole in the first sidewall and a second hole in the second sidewall, respectively.

First claim

The invention claimed is:

1. A rectangular baler having a front end for connection with a tractor and a back end, the baler comprising:
a chassis comprising a first sidewall and a second sidewall;
a compacting plunger supported on the chassis for advancing crop material;
a bale chamber between the compacting plunger and the back end, the bale chamber adapted to contain one or more bales, the first and second sidewalls extending from the front end toward the back end; and
a pull rod connecting the first sidewall and the second sidewall, at a location between the plunger and the front end, the pull rod having a first and a second end part extending freely through a first hole in the first sidewall and a second hole in the second sidewall, respectively, the first and second end parts of the pull rod provided with a first blocking element and a second blocking element preventing that the first and second end parts move inwardly through the respective first and second holes while allowing that the first and second end parts move outwardly through the respective first and second holes;
wherein the first sidewall comprises a first pull wall portion at the front end and a first frame wall portion connected to the chassis,
wherein the second sidewall comprises a second pull wall portion at the front end and a second frame wall portion connected to the chassis,
wherein the first and second frame wall portions are connected at a connection area to the first and second pull wall portions, respectively,
wherein the first hole extends through the first pull wall portion and the first frame wall portion at the connection area, and
wherein the second hole extends through the second pull wall portion and the second frame wall portion at the connection area.

2. The rectangular baler of claim 1 , wherein the pull rod connects an upper half of the first sidewall with an upper half of the second sidewall.

3. The rectangular baler of claim 1 , wherein the pull rod connects a top part of the first sidewall with a top part of the second sidewall.

4. The rectangular baler of claim 1 , wherein the first and second sidewalls each have a front end wall part and a back end wall part which is under an angle with respect to a front end wall part, such that the front end wall part of the first sidewall approaches the front end wall part of the second sidewall, when looking into the direction of the front end, wherein each front end wall part is connected via a transition area, in particular a bending line, to the corresponding back end wall part.

5. The rectangular baler of claim 1 , wherein the first and second pull wall portions each have a first part which is bent with respect to a second part, the second part of the first and second pull wall portion being aligned with the first and second frame wall portions, respectively, such that the first parts constitute the front end wall parts and the second parts together with the first and second frame wall portions constitute the back end wall parts.

6. The rectangular baler of claim 4 , wherein the distance between the pull rod and a plane through a transition zone of the first and second sidewalls is smaller than 75 cm, preferably smaller than 50 cm.

7. The rectangular baler of claim 1 , wherein the first and second frame wall portions are first and second double-walled portions, and wherein the first and second pull wall portion have a first and second edge, respectively, which is arranged between the walls of the first and second double walled portions, respectively, wherein the first hole and the second hole is a through-hole extending through the walls of the first and second double walled portion and through the edge of the first and second pull wall portion, respectively.

8. The rectangular baler of claim 1 , wherein the first and second pull wall portions have a first and second upper edge with a U-shape, wherein a hollow cylindrical part is fixed in the first and second U-shaped upper edges, and wherein the hollow cylindrical part of the first and second pull wall portion is part of the first and second holes, respectively.

9. The rectangular baler of claim 1 , wherein the first and second sidewalls are connected at the front end via a reinforced plate-like element, which plate-like element is provided with a hole for a PTO drive shaft.

10. The rectangular baler of claim 1 , further comprising a first hollow bolt and a second hollow bolt arranged in the first hole and the second hole, respectively, wherein the first and second end parts of the pull rod extend through the first and second bolts, respectively.

11. The rectangular baler of claim 1 , wherein the first and second blocking elements each comprise at least one nut.

12. The rectangular baler of claim 1 , further comprising a gearbox, wherein there is provided a carrying member between the first sidewall and the second sidewall, the carrying member carrying a lower part of the gearbox.

13. The rectangular baler of claim 12 , wherein the carrying member is arranged between the first sidewall and the second sidewall, wherein the pull rod is arranged higher than the carrying member, and, seen in a top view, closer to the front end than the carrying member.

14. The rectangular baler of claim 1 , wherein the pull rod has a diameter which is smaller than 30 mm.

15. A rectangular baler having a front end for connection with a tractor and a back end, the baler comprising:
a chassis comprising a first sidewall and a second sidewall;
a compacting plunger supported on the chassis for advancing crop material;
a bale chamber between the compacting plunger and the back end, the bale chamber adapted to contain one or more bales, the first and second sidewalls extending from the front end toward the back end;
a pull rod connecting the first sidewall and the second sidewall, at a location between the plunger and the front end, the pull rod having a first and a second end part extending freely through a first hole in the first sidewall and a second hole in the second sidewall, respectively, the first and second end parts of the pull rod provided with a first blocking element and a second blocking element preventing that the first and second end parts move through the first and second holes, respectively; and
a first hollow bolt and a second hollow bolt arranged in the first hole and the second hole, respectively;
wherein the first and second end parts of the pull rod extend through the first and second bolt, respectively,
wherein the first sidewall comprises a first pull wall portion at the front end and a first frame wall portion connected to the chassis,
wherein the second sidewall comprises a second pull wall portion at the front end and a second frame wall portion connected to the chassis,
wherein the first and second frame wall portions are connected at a connection area to the first and second pull wall portions, respectively,
wherein the first hole extends through the first pull wall portion and the first frame wall portion at the connection area, and
wherein the second hole extends through the second pull wall portion and the second frame wall portion at the connection area.

16. A rectangular baler having a front end for connection with a tractor and a back end, the baler comprising:
a chassis comprising a first sidewall and a second sidewall;
a compacting plunger supported on the chassis for advancing crop material;
a bale chamber between the compacting plunger and the back end, the bale chamber adapted to contain one or more bales, the first and second sidewalls extending from the front end toward the back
