Through the cross-biting setting, when the grain slag mixture is brought to the second crushing area of bottom, the residue of the grain slag mixture can be fully crushed, and the crushing effect is further improved.

According to an embodiment of the application, as shown in fig. 8, the shape of the limiting portion 1102 is arc-shaped, and the distance from the outer side surface of the limiting portion 1102 on the same spacer 11 to the rotary shaft 1001 of the hob 10 is smaller than the distance from the tooth tip of the cutter tooth 1003 to the rotary shaft 1001 of the hob 10, that is, the cutter tooth 1003 of the tooth plate 1002 is exposed out of the limiting portion 1102, so that the cutter tooth 1003 of the tooth plates 1002 on two sides can be conveniently washed by water flow, jamming is further prevented, and crushing efficiency is further improved.

According to one embodiment of the present application, as shown in fig. 8, the spacer 11 further includes a mounting portion 1105, the mounting portion 1105 is connected above the limiting portion 1102, the mounting portion 1105 is provided with first mounting holes 1106, the first mounting holes 1106 of the mounting portions 1105 of the plurality of spacers 11 are aligned along the axial direction, and fastening is achieved by a first nut after penetrating all the first mounting holes 1106 by a first fastening bolt; and the supporting portion 1101 is provided with second mounting holes 1107, the second mounting holes 1107 of the supporting portion 1101 of the plurality of spacers 11 are aligned in the axial direction, and fastening is achieved by second nuts after penetrating all the second mounting holes 1107 by second fastening bolts.

According to one embodiment of the present application, as shown in fig. 6 to 8, a spacer 12 is provided between the mounting portions 1105 of each adjacent two of the spacers 11 for spacing the adjacent two of the spacers 11; and the partition plate 12 is provided with a third mounting hole 1201, the third mounting hole 1201 is aligned with the first mounting hole 1106, and then the first fastening bolt penetrates through all the first mounting holes 1106 and the third mounting hole 1201 and then is fastened through the first nut. It should be appreciated that the spacer 12 is mounted in a position that avoids interference with the rotation of the blades 1002 of the hob 10.

According to one embodiment of the present application, as shown in fig. 10, the outer peripheral surface of the tooth plate 1002 of the hob 10 is provided with 6 to 8 cutter teeth 1003 at intervals in the circumferential direction, in other words, 6 to 8 cutter teeth 1003 are provided at intervals in the circumferential direction of the tooth plate 1002 at the edges of the tooth plate 1002.

It should be noted that, if the number of cutter teeth 1003 of the single tooth plate 1002 is smaller than 6 to 8, the biting force of the hob 10 is increased, so that the driving force of the second driving member for driving the hob to rotate is increased, and the energy consumption of the second driving member is further increased; if the number of cutter teeth 1003 on a single blade 1002 is greater than 6-8, the cutter teeth 1003 on the blade 1002 are denser, and larger-sized cake residues in the water and slag mixture are difficult to bite. Specifically, since the number of cutter teeth is greater than 6 to 8, the number of cutter teeth 1003 simultaneously contacting the block-shaped residue is increased, and the block-shaped residue is difficult to be brought into the first crushing area between the cutter teeth 1003 of the two sets of hob 10, thereby resulting in an inability to crush the residue effectively. Therefore, by setting the number of cutter teeth 1003 of the tooth plate 1002 to be 6-8, the energy consumption of the second driving member can be reduced, and residues in the water slag mixture can be ensured to enter the first crushing area quickly, so that the crushing effect is improved.

According to one embodiment of the present application, the smaller the distance between adjacent tooth plates 1002 on the same rotation shaft 1001 of the hob 10, the larger the friction force between the adjacent tooth plates 1002 and another set of tooth plates 1002, so that the driving force of the second driving member for driving the hob 10 to rotate is increased, and the energy consumption of the driving member is further increased. Therefore, the interval between adjacent tooth plates 1002 on the same rotating shaft 1001 of the hob 10 is set to be 1.5mm-2.5mm, so that the particle size of the crushed residues can be guaranteed to reach the emission requirement, and simultaneously, the additional friction force generated in the operation process can be reduced, and the energy consumption of the second driving piece is further reduced.

According to an embodiment of the present application, as shown in fig. 10 and 11, the cutter teeth 1003 of the plurality of tooth plates 1002 on the same rotating shaft 1001 of the hob 10 form a cutter tooth group along the axial direction, when the plurality of cutter teeth 1003 are provided on the tooth plates 1002, the corresponding cutter tooth groups are also formed into multiple groups, in each group of cutter tooth groups, the plurality of cutter teeth 1003 are offset from each other so that a rotation position difference is formed between the cutter teeth 1003 of each adjacent two tooth plates 1002, i.e. the adjacent two tooth plates 1002 have a certain deflection angle relative to the rotating shaft 1001 of the hob 10 so that the cutter teeth 1003 are rotationally offset from each other, wherein the deflection directions of the tooth plates 1002 can be clockwise or both anticlockwise, i.e. deflect along the same rotation direction, the deflection directions of the tooth plates 1002 can be partially clockwise, and the other part anticlockwise, i.e. deflect along different rotation directions, and can be correspondingly adjusted according to actual crushing conditions. The rotary potential difference is set through the cutter teeth 1003, so that the tooth plates 1002 of the two groups of hob 10 can be guaranteed to fully bite the residues, and the crushing effect is improved.

In the related art, the orthographic projections of the cutter teeth 1003 of the plurality of tooth plates 1002 on the rotating shaft 1001 of the hob 10 along the axial direction are generally overlapped, so that the pressure applied to the hob 10 is concentrated on the cutter teeth along the axial direction, and after the massive residues or hard objects are crushed for a long time, the hob is easily damaged. This application sets up rotatory potential difference through cutter tooth 1003, can make the pressure that hobbing cutter 10 received carry out corresponding distribution along rotatory potential difference, and the global dispersion of hobbing cutter 10 pivot 1001 is followed to the pressure promptly, and then can disperse the pressure of hobbing cutter 10 cutter body, avoids the pressure too concentrated, is favorable to protecting hobbing cutter 10, and then prolongs reducing mechanism's life.

According to one embodiment of the present application, the rotational head of the cutter teeth 1003 of adjacent two teeth 1002 is set to 4 ° -6 °.

The rotary head angle is set to be 4-6 degrees, so that the manufacturability of the hob 10 hob body is simultaneously met on the premise of meeting the engagement performance.

Specifically, the number 1 cutter tooth and the number 2 cutter tooth have a rotation potential difference of 4 ° -6 ° (e.g., 5 °), the number 2 cutter tooth and the number 3 cutter tooth also have a rotation potential difference of 4 ° -6 ° (e.g., 5 °), and so on, so that a rotation potential difference of a certain angle is formed between the adjacent cutter teeth 1003 along the same deflection direction, which can ensure that the hob 10 fully engages with the residue, and can maximize the pressure dispersion effect that the hob 10 receives.

According to an embodiment of the application, the rotary shaft 1001 of the hob 10 is connected with a second driving member, the second driving member drives the rotary shaft 1001 to rotate so as to enable the hob 10 to rotate, and the second driving member can drive the hob 10 to be in a low-noise running state below 47 deciliters, so that noise is prevented from being generated, and the use experience of the crushing device is improved. Specifically, the input voltage of the second driving element is adjusted to reduce the rotation speed of the second driving element, and the constant voltage is set to be 100V-120V (220V at full load), so that the second driving element can output a constant low rotation speed, for example, 90RPM-120RPM, and noise can be greatly reduced under the condition of low rotation speed compared with the condition of full load. In addition, if residues which are difficult to crush and have high hardness are contained in the water slag mixture, the input voltage of the second driving piece can be increased in real time so as to meet the instantaneous high torque force requirement. When the crushing is successful, the input voltage of the second driving member is restored to a low voltage state, so that the user always feels the low noise state in the whole process.
