Detailed Description

Example 1

As shown in fig. 1 to 3, the present embodiment provides a straw pulverizing apparatus including: a comminution mechanism 10, a material handling mechanism 20 and a connector 30.

Wherein, crushing mechanism 10 has crushing input, crushing output that the level set up, realizes the horizontal pan feeding and the ejection of compact of straw. A first supporting frame 40 is arranged below the crushing mechanism 10, and the first supporting frame 40 is used for supporting the crushing mechanism 10. The comminution mechanism 10 comprises at least a comminution assembly 11, a drive assembly 12 in driving connection with the comminution assembly 11. The straw to be crushed is input from the crushing input end and contacts the crushing assembly 11; the straw is crushed by the crushing assembly 11 and then output from the crushing output end.

As shown in fig. 2, the pulverizing assembly 11 includes: at least two sets of rotating shafts 111, and several sets of crushing blades 112. In the present embodiment, the rotation shafts 111 are provided in two groups to be described. The two sets of rotating shafts 111 are in transmission connection with the driving assembly 12, and the driving assembly 12 drives the rotating shafts 111 to rotate. The drive assembly 12 includes: the servo motor, the driving wheel, the driving belt and other parts for driving are not described in detail herein. Each of the rotation shafts 111 is provided with a plurality of groups of crushing blades 112 along the length direction thereof. The pulverizing blades 112 on the adjacent rotating shafts 111 are sequentially arranged at intervals.

The material transporting mechanism 20 is arranged below the crushing output end. A second supporting frame 50 is disposed below the material transporting mechanism 20, and the second supporting frame 50 is used for supporting the material transporting mechanism 20. The second supporting frame 50 is lower than the first supporting frame 40, so that the height of the crushing mechanism 10 is higher than that of the material conveying mechanism 20.

The material handling mechanism 20 includes at least: housing 21, transport assembly 22, and power source 23. Wherein the interior of the housing 21 is hollow. One end of the shell 21 is provided with a material input end 211, and the other end is provided with a material output end 212. In other words, as shown in fig. 1, one end of the housing 21 is provided with a material input port (i.e. material input port 211), and the other end is provided with a material output port (i.e. material output port 212). The material input end 211 is arranged close to the crushing output end; the material outlet 212 is provided at one end of the housing 21 in a direction away from the crushing outlet.
