Detailed ways

In order for those skilled in the art to better understand the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the following is only exemplary and does not limit the protection scope of the present invention.

As shown in Figure 1 and Figure 2, a multifunctional semi-wet material grinder includes a body 15, an upper feed bin 4 and a crushing system; the upper feed bin 4 is cylindrical, and the top of the upper feed bin 4 has a straw fiber feed port 1 and the semi-wet material inlet 5, the bottom of the feeding bin 4 is provided with a discharge port 14, and the discharge port 14 is provided with a pull-out fixed frame 21 and a screen 12 arranged on the pull-out fixed frame 21, It is convenient to replace screens 12 of different meshes according to needs; the crushing system includes a chopping mechanism, a kneading mechanism and a hammer crushing mechanism, wherein the chopping mechanism includes a main shaft 20, a drive unit that drives the main shaft 20 to rotate, and is arranged on the main shaft 20 close to the straw The three moving knives 17 of the fiber feeding port 1 and the two ends of the main shaft 20 are equipped with bearing housings 10 with bearings. Comprising a rubbing plate 18 arranged on the inner wall of the upper bin 4, the hammer crushing mechanism includes two hammer crushing shafts 19 arranged symmetrically about the axis of the main shaft 20, hammers 7 arranged at intervals on the hammer crushing shaft 19, and each The tool holder assembly 16 of the hammer 7 and a plurality of shifting components arranged between the hammers 7, the shifting component includes a disc 22 fixed on the main shaft 20 and a shifting piece 8 detachably installed on the disc 22 , the paddles 8 are arranged in a helical line along the main shaft 20 .

As shown in Figure 1, the drive unit includes a motor 13 and a belt drive assembly 11 connected to the motor 13, the hammer mill shaft 19 and the two ends of the main shaft 20 are connected as a whole through a connecting frame 23, and of course those skilled in the art can connect the belt drive assembly as required 11 change to gear or other modes of transmission.

As shown in Figure 2, the discharge port 14 is arranged at the end of the main shaft 20, and a return plectrum assembly is arranged near the end of the main shaft 20, the return plectrum assembly includes a return plectrum 9 installed on the connecting frame 23, and the return plectrum The pick piece 9 is opposite to the screw direction of the pick piece 8 . This structural setting is convenient to push the material at the end of the upper silo 4 back to the discharge port in reverse to prevent material clogging, and it can also return the material that does not meet the particle size requirement of the screen 12 to the upper hopper to continue crushing until the particle size is less than The aperture of the screen 12.

As shown in Figure 4, the straw fiber feed port 1 is arranged tangentially along the rotation direction of the main shaft 20, which is convenient for feeding on the one hand, and can effectively prevent the material from bursting out; as shown in Figure 3, the discharge port 14 rotates along the main shaft 20 The direction is tangentially arranged, and the opening position exceeds the middle line of the upper material bin 4, which is beneficial to the maximum discharge and effectively solves the common material blocking phenomenon in the crushing process.

In this embodiment, a straw fiber feed port baffle 3 is installed on the straw fiber feed port 1, and a semi-wet feed port baffle 6 is installed on the semi-wet material feed port 5. When one of the feed ports is used alone , the baffle plate on the other feed port can be used to block the feed port to prevent the material from being taken out when the main shaft 20 rotates at a high speed.

In this embodiment, a baffle plate 2 is installed through a pin shaft in the straw fiber feed port 1. The material baffle plate 2 is made of rubber, and the material baffle plate 2 can rotate around the pin shaft. On the one hand, it does not affect the feeding, on the other hand, it can While feeding the material, it blocks the material that bursts out when the crushed material hurts people.

In this embodiment, the movable knife 17 is made of wear-resistant alloy steel, which can ensure the chopping effect for a long time.

Utilize the working process of the present invention as follows:

When it is necessary to crush long straw fiber materials, the material enters through the straw fiber feed port 1, and the baffle plate 2 on the straw fiber feed port 1 can effectively prevent the material from bursting out during crushing. After the straw enters the feeding bin 4 The straw is cut off by the moving knife 16 rotating at a high speed along the main shaft 20, and the material is pushed towards the discharge port 14 through the action of the material shifter 8 on the main shaft 20 through the action of screw propulsion. During this period, the material on the wall of the upper bin 4 The installed rubbing plate 17 pulls the straw into filaments, and the hammer blade 7 further pulverizes the material through high-speed shearing and hammering. When the pulverized material can pass through the screen 12, it flows out of the discharge port 13. Larger particles continue to stay in the upper silo 4 for further pulverization until the particle size is smaller than the size of the sieve 12 sieve holes. When crushing general materials, the material can be poured directly through the semi-wet material feed port 5, the semi-wet material feed port 5 is facing the initial position of the hammer 7, and the material is not cut by the moving knife 16 and is directly fed by the hammer 7 is crushed, and under the screw propulsion of the material shifting piece 8, it flows to the discharge port 14. When the material is crushed to a small enough size, it passes through the screen 12 and flows out from the discharge port 14. When the material is more viscous, it is To prevent the sieve 12 from clogging, the sieve 12 can be pulled out to facilitate discharging.

Although the specific implementation of the present invention has been described above in conjunction with the accompanying drawings, it is not a limitation to the scope of protection of the present invention. Those skilled in the art should understand that on the basis of the technical solution of the present invention, those skilled in the art do not need to pay creative efforts. Various modifications or deformations that can be made by labor are still within the protection scope of the present invention.
