Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and in particular to a device for breaking or pulverizing straw bales. Background Art

[0002] After the harvest, the straw is scattered in the field, affecting the field management. Farmers often burn straw, which not only pollutes the atmosphere, but also affects traffic safety. The mechanized method of picking up, baling and packing corn straw can not only greatly reduce the labor intensity of farmers and save labor, but also provide more feed and production materials for family and large-scale breeding, papermaking, straw power generation and alcohol manufacturing. It is also convenient for transportation and storage, and the straw is comprehensively utilized and the environment is effectively protected. Therefore, it is necessary to use a corresponding baler to bale the straw, but before using or feeding, the corresponding crushing equipment needs to be used to crush and dust the straw. The existing method generally uses a cutter to repeatedly cut and chop the straw bales or straw bags to crush them, but this crushing method not only requires manual assistance, but also has low efficiency and is not suitable for large-scale crushing. The grass is not evenly delivered, cannot be broken, the bale is hard, or the grass is stuck during the grass delivery process. At the same time, the crushing effect needs to be improved, and manual assistance is required to feed the grass during use, which is prone to personal injury accidents. Utility Model Content

Its function is to vibrate the straw bale entering the feed port. The principle is that the straw bale will be vibrated by the vibrating blade 14 every time the main cutter disc 4 rotates one circle, so that the straw bale can automatically enter at a uniform speed, thereby breaking and chopping the grass.

[0030] The driving device includes a motor 8, a pulley 10, a main shaft 11, a driven shaft 9, and a bearing 12. The motor 8 is installed on a support frame 1 arranged at the bottom of the shell 2. The driven shaft 9 is connected to the output end of the motor 8. One end of the main shaft 11 is connected to the driven shaft through the pulley 10, and the other end of the main shaft 11 is connected to the shell 2 through a bearing 12.

The hay bales are placed on the feeding platform 3 and enter the feeding port. Since the specifications of the packaged forage grass are not uniform, the height of the limiting plate 6 is adjusted to ensure that the hay bales enter the feeding port stably. The feeding platform 3 is parallel to the horizontal plane, and the main cutter disc 4 is inclined at an angle of about 40 degrees to the horizontal plane, so that the hay bales are automatically fed into the feeding port through gravity and the operation of the machine.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
