Description

An automatic locking and opening device for a round straw bale baler chamber and a baler chamber

Technical field

The invention relates to the technical field of modern agricultural machinery, and in particular to an automatic locking and opening device for a round straw bale baler chamber and a baler chamber.

Background technique

At present, domestic green feed is mainly stored in silage ponds and cellars, which requires high investment and can only meet the needs of users. The stored feed is prone to oxidative deterioration and has low utilization rate. It is difficult to realize the commercial circulation of silage, which hinders the large-scale development of the animal husbandry industry. Wrapped film silage has attracted more and more attention from the domestic animal husbandry industry due to its advantages of convenient storage, good sealing, good feed quality, and high utilization rate. In particular, crushed silage requires the bale to have a certain density and good sealing after coating. Therefore, the wrapped silage is mainly round bales.

Round balers mainly include picking and baling machines, fixed small round baling machines, aggregate baling integrated machines and baling and wrapping integrated machines. The locking and opening device of the round bale baler cabin is to ensure the density of the bales. It is a key device for bale quality and equipment safety. At present, domestic small round balers mainly use manual opening, while large balers use manual mechanical opening or automatic control.

There is a round bale release device in a patent. The two ends of the rear roller backpack opening and closing cylinder are respectively hinged with the rear roller backpack and the rear end of the locking hook. The front hook of the locking hook hooks the rolling shaft, and the tension spring The upper end hooks the middle part of the locking hook, and the lower end hooks the lower part of the front roller chamber. The sensor signaling mechanism is arranged on the lower side of the tension spring. The rear part of the locking hook is hinged with the lower part of the front drum chamber through the support spindle. The floating support mechanism of the locking hook is set on one side of the support spindle. This device requires manual opening of the hatch to release the straw bales, and the degree of mechanization is low.

Another patent provides an opening and locking mechanism, the axes of the threaded shaft and the threaded barrel coincide, the threaded shaft and the threaded barrel are threaded and can rotate relatively; the threaded shaft is transmission connected with the driving mechanism, and the driving mechanism is hinged with the first base; thread The barrel is hingedly connected to the second base. The upper part of the front frame and the upper part of the rear frame are hinged; the first base is connected with the front frame; the second base is fixedly connected with the rear frame. The opening mechanism has poor stability and is not conducive to high-speed automatic control.

Another patent provides an unloading interlocking device. When the backpack is closed, the front end of the lock hook hooks the lock bolt. The upper part of the lock hook is hinged with the full bag alarm mechanism provided on the upper part of the front backpack, the upper end of the vertical plate is hinged with the full bag indicating mechanism through the first connecting rod, and the back backpack opening operating mechanism is provided on the lower part of the front backpack. This mechanism is inconvenient for the adjustment of baling pressure and high-speed automatic continuous operation.

To sum up, in the existing technology, there is still a lack of effective solutions to the problem that the chamber of the round bale baler cannot be effectively opened and closed automatically.
