[0002] In the process of livestock farming, various grains including soybeans, corn, etc. usually need to be crushed and then mixed. The crushed grain powder is mixed with other nutrients in proportion. The crushing process of these grains will use crusher equipment.

[0003] In the prior art, a crusher generally includes a crushing component, which uses a rotor shear slice, etc. to crush grain particles. However, when the crusher is in use, due to factors such as the rotor speed, larger particles will be omitted during the crushing process of the grains, which will affect the quality of the produced feed. The omission of such large grain particles of grains requires repeated crushing treatment, which adds cumbersome steps of screening, re-feeding, and re-crushing.

[0004] Therefore, a modular multi-chamber integrated hammer mill is needed to solve the problems of large particle omission and inconvenient cyclic crushing treatment in the prior art when grains are crushed by the rotor shear method. Content of the Utility Model

The circulating grinding mechanism includes a partition board 18, a grinding tooth plate 19 and a through hole 20. Two groups of partition boards 18 are respectively arranged above and below the second crushing box 2, the grinding tooth plate 19 is fixed at the lower end of the partition board 18, and the through hole 20 is opened on the upper end surface of the partition board 18.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 3 , it is specifically noted that a first rotating shaft 4 is fixedly disposed through the inside of the first hammer blade holder 5, a second rotating shaft 6 is fixedly disposed through the inside of the second hammer blade holder 7, and a third rotating shaft 8 is fixedly disposed through the inside of the third hammer blade holder 9.

[0026] Further, as shown in Figure 3 , it is specifically noted that a first driven wheel 10 is fixedly sleeved on the surface of the first rotating shaft 4, a second driven wheel 11 is fixedly sleeved on the surface of the second rotating shaft 6, and a driving wheel 13 is fixedly sleeved on the surface of the third rotating shaft 8.

[0027] Further, as shown in Figure 1 , Figure 2 and Figure 4 , it is specifically noted that a first transmission belt 12 is disposed between the first driven wheel 10 and the second driven wheel 11, and a second transmission belt 14 is disposed between the second driven wheel 11 and the driving wheel 13.

[0028] Further, as shown in Figure 4 , it is specifically noted that a driving motor 21 is fixed on a supporting plate on one side surface of the third crushing box 3, and one end of the third rotating shaft 8 is fixed on the output end of the driving motor 21.

[0029] Further, as shown in Figure 1 , it is specifically noted that partition frames 17 are fixed on both the upper end surface and the lower end surface of the second crushing box 2, and a partition plate 18 is fixed on the inner wall of the partition frame 17.

[0030] Further, as shown in Figure 1 , it is specifically noted that a through hole 20 is disposed above the adjacent gaps of the grinding tooth plates 19, and two grinding tooth plates 19 are respectively disposed above the second hammer blade holder 7 and the third hammer blade holder 9.

[0031] Further, as shown in Figure 1 , it is specifically noted that a feed inlet 15 is disposed at the upper end of the first crushing box 1, and a discharge seat 16 is disposed below the third crushing box 3.

[0032] This solution has the following working process: Before use, the grains to be crushed are fed into the first crushing box 1 along the feed inlet 15. The first hammer rack 5 inside the first crushing box 1 rotates at a high speed and uses the hammer pieces to crush the grains. When the driving motor 21 drives the third rotating shaft 8 to rotate, through the cooperation of the driving wheel 13, the second driven wheel 11, the first driven wheel 10, the first transmission belt 12 and the second transmission belt 14, it is possible to control the synchronous rotation of the first hammer rack 5, the second hammer rack 7 and the third hammer rack 9.

[0033] When the first hammer rack 5, the second hammer rack 7 and the third hammer rack 9 are crushing, the grain material collides with the first hammer rack 5, the second hammer rack 7 and the third hammer rack 9 and then impacts on the grinding tooth plate 19 in the upper grinding area. Since the partition plate 18 is provided with through holes 20 communicating with the upper chamber on its surface, in this way, the grain material can return to the upper chamber through the gaps of the grinding tooth plate 19 under the action of the impact force. This method can form multiple impacts and rebounds, and the auxiliary hammer plates and reinforced hammer pieces can form a grinding and crushing effect. After repeated cycles, the probability of the material being struck and impacted is increased. The circulating grinding mechanism formed by the partition plate 18, the grinding tooth plate 19 and the through holes 20 improves the grinding efficiency and quality, reduces energy consumption and increases efficiency.

[0034] In summary: It is possible to control the synchronous rotation of the first hammer rack 5, the second hammer rack 7 and the third hammer rack 9, and the first crushing box 1, the second crushing box 2 and the third crushing box 3 form three consecutive crushing chambers, where the upper-layer hammer pieces can initially crush the material, and after crushing, it is transmitted to the next chamber for further crushing, thereby further improving the crushing effect, increasing efficiency, reducing energy consumption and maintenance costs; the grain material can collide with the grinding tooth plate 19 under the action of the impact force and return to the upper chamber through the gaps. This method can form multiple impacts and rebounds, and the auxiliary hammer plates and reinforced hammer pieces can form a grinding and crushing effect. After repeated cycles, the probability of the material being struck and impacted is increased. The circulating grinding mechanism formed by the partition plate 18, the grinding tooth plate 19 and the through holes 20 improves the grinding efficiency and quality, reduces energy consumption and increases efficiency.
