DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2The utility model provides a technical solution: an energy-saving crushing device for piglet feed, including a box body 1, a preliminary crushing chamber 2, a secondary crushing chamber 3, a spiral stirring roller 4, a hammering component 5 and an arc-shaped screen plate 6. The preliminary crushing chamber 2 is arranged on the upper side of the box body 1, and a feeding port is arranged on the side wall of the preliminary crushing chamber 2; the secondary crushing chamber 3 is arranged on the lower side of the box body 1; the spiral stirring roller 4 is arranged in the crushing chamber 2; the hammering component 5 is arranged in the secondary crushing chamber 3; the arc-shaped screen plate 6 is arranged at the lower end of the secondary crushing chamber 3, and the processing particle size of the feed is required to be able to pass through the sieve holes of the arc-shaped screen plate 6. The operation mainly utilizes the impact of the hammering component 5 and the friction between the arc-shaped screen plate 6 and the material. The hammer assembly 5 comprises a rotating shaft 5-1, a main hammer piece 5-2, a connecting column 5-3, a secondary hammer piece 5-4 and a rib plate 5-5. The rotating shaft 5-1 is transversely arranged in the cavity of the secondary crushing chamber 3. The main hammer piece 5-2 is arranged on the shaft of the rotating shaft 5-1. At the same time, the main hammer piece 5-2 and the secondary hammer piece 5-4 are parallel to each other. The connecting column 5-3 and the rib plate 5-5 are both arranged between the main hammer piece 5-2 and the secondary hammer piece 5-4. The distance between the rib plate 5-5 and the rotating shaft 5-1 is greater than the distance between the connecting column 5-3 and the rotating shaft 5-1. The connecting column 5-3, the secondary hammer piece 5-4 and the rib plate 5-5 are adjusted in number according to the capacity of the secondary crushing chamber 3, so that the hammering path of the hammering assembly 5 meets the hammering demand in the secondary crushing chamber 3.

[0017] Specifically, a wide-diameter screen 7 is provided between the primary crushing chamber 2 and the secondary crushing chamber 3. The mesh diameter of the wide-diameter screen 7 is larger than the mesh diameter of the arc-shaped screen plate 6. The spiral stirring roller 4 preliminarily crushes the material, and the preliminarily crushed material falls through the wide-diameter screen 7, thereby improving the crushing efficiency of the hammering assembly 5 in the secondary crushing chamber 3.

[0018] Specifically, the number of the spiral stirring rollers 4 is two, both of which are longitudinally arranged in the preliminary crushing chamber 2, driven by the first driving motor 8, and the positions of the two spiral stirring rollers 4 are adjacent.

The coupling 10 is a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive loads and play a role in overload protection.

[0020] Specifically, the hammering path of the hammering assembly 5 coincides with the inner end surface of the arc-shaped screen plate 6 .

[0021] Working principle: When the utility model is working, the hammer assembly 5 is designed to have a main hammer piece 5-2 and a secondary hammer piece 5-4 connected by a connecting column 5-3 and a rib plate 5-5. The rib plate 5-5 can increase the wind speed and wind pressure of the secondary crushing chamber 3, which is beneficial to the improvement of feeding efficiency and the pressure difference of discharging, thereby improving the crushing efficiency of the material. After the material is broken by the main hammer piece 5-2 and the secondary hammer piece 5-4, it flies to the screen of the arc screen plate 6 at a higher speed, is further rubbed and crushed, and finally crushed into small particles.
