Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a roll baler that collects collected materials such as waste straw and cut down grass scattered on the ground, compresses them into roll-shaped bales, and packs them. Regarding.

(Conventional Wave) Roll balers, as described in the Publications No. 57-46806 and the Publications No. 15285-1985, pick up collected items from the ground using a pickup device installed at the front of the machine. The material is sent into the bale forming chamber and compressed and packed into rolled bales.The outer periphery of the bale forming chamber consists of a lower conveying device and an upper bundling device, which rotates and compresses the collected materials. The rear side rotates upward to open the bale forming chamber, and the packed bale is rolled out to the rear of the machine by a conveying device.

(Problem to be Solved by the Invention) In the conventional configuration described above, the collected material sent into the bale forming chamber by the conveying device is prevented from being discharged from the rear by the bundling device, and the amount of collected material that is blocked is As the number of collected items increases, the bundler sends them upward and begins to rotate, and as the number of collected items increases further, the bundler compresses them into a roll.

Therefore, at the lower end portion of the bundling device, which blocks the collected items on the conveying device that feeds the bundle backwards and feeds them upward, the collected items may be discharged rearward as they are.

This invention prevents the collected materials from being sent out by such a conveying device and ensures that the collected materials are stored in the bale forming chamber by the bundling device.

(Means for Solving the Problems) Therefore, in the present invention, the outer periphery of the bale forming chamber 1 is configured with a lower conveying device 2 and an upper bundling device 3, and the bundling device 3
In a roll baler whose rear side is rotated upward to open the bale forming chamber 1, the V9 feeding device 2 is extended rearward longer than the lower end 4 of the bundling device 3, and the lower end 4 of the bundling device 3 is It is constructed so that it can be fixed in a pressed state onto the conveying device 2.

(Operations and Effects of the Invention) The collected material sent from the front side on the conveying device 2 into the bale forming chamber 1 is prevented from moving backward by the lower end 4 of the bundling device 3 and As it is rotated by the upward feeding action, as the amount increases, it is compressed into a roll shape and its diameter increases.

Since the lower end 4 of the bundling device 3 is fixed in a pressed state onto the conveying device 2, the east bundling device 3 and the L shedding device 2 are in very close positions, and there is a small gap and the collected items are transferred to the conveying device 2. It will not be discharged from the Hale molding chamber 1 due to the feeding action.
