Description

Auxiliary feeding device for hay baler

technical field

The invention relates to an auxiliary feeding device of a straw baler breaker, which enables the straw to smoothly enter the processing surface of a milling cutter and ensures that the straw is continuously broken.

Background technique

As a large agricultural country, our country is rich in biomass resources. In the countryside of our country, there are mainly rice straw, wheat straw, and corn straw. It is estimated that my country's annual crop straw output reaches more than 700 million tons. Although a small part of the straw has been used for returning to the field, feed and industrial raw materials, as well as farmers' life and fuel, a large part of the straw is still directly burned in the field. , resulting in a great waste of biomass energy, and at the same time, air pollution and fire safety problems are also very harmful, and even affect traffic and the health of the people.

The self-propelled straw picking and bundling machine is an indispensable and preferred equipment for animal husbandry and paper making. After the machine is put on the market, it will solve the problem of straw recycling and improve the environmental pollution caused by straw burning in rural areas.

With the development of the straw baler, the straw breaker came into being. The straw bale is opened by the straw bale breaker, and the straw bale is roughly processed at the same time to prepare for the next process of using straw. The working principle of the straw baler machine is to drive the milling cutters on the cutter roller shaft to rotate against each other through the high-power motor and the reduction box, so as to achieve the purpose of squeezing, shredding and shearing the materials. Under normal working conditions, the cutter speed of the straw baler breaker is low, the safety performance is high, the noise is low, the energy consumption is low, and the practicability is strong. However, it often happens that the straw bales are covered by the cutter at the feed inlet and cannot be unloaded. .

When the bale falls into the rectangular funnel-shaped feed opening, only a few milling cutter tips exert downward force on the bale due to the helical arrangement of the milling cutters, and most of the milling cutters exert upward force on the bale through the back of the cutter. At the same time, part of the tip of the knife generates an upward support force on the bale during the rotation process; when the support force generated by the milling cutter on the bale is greater than the downward hooking force of the milling cutter on the bale, it will appear The phenomenon that the bale is covered by the milling cutter and cannot be unloaded.

When the bale is blocked by the milling cutter and cannot be unloaded, the conventional solution is as follows: the worker stands on the high platform next to the rectangular funnel-shaped feed inlet, and uses a wooden stick to pound down the covered bale. This method It not only affects the working efficiency of the baler breaker, but also increases the labor intensity, and sometimes even the milling cutter will bite the wooden stick, which poses a serious threat to the normal operation of the machine and the life safety of workers.

It can be seen that the design of the feed inlet of the existing baler breaker still has defects and needs to be improved to realize the continuous, reliable and safe feeding function of the bale.
