DETAILED DESCRIPTION

[0036] The present application is further described in detail by the following figures and specific embodiments. The embodiments of the present application are given for illustration and description only, and are not intended to be exhaustive or to limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application for various embodiments with various modifications as are suited to the particular use contemplated.

[0037] The first embodiment, as Figures 1-4The wood chip granulator of novel structure provided by the present application comprises a motor 1, a fixed rail 2, a granulator 3 and a disengager 5, the bottom of the motor 1 is slidably connected to the inside of the fixed rail 2, the outside of the output end of the motor 1 is connected to the disengager 5, the end of the disengager 5 away from the motor 1 is fixedly connected to the outside of the granulator 3, and the bottom of the granulator 3 is fixedly connected to a support plate 4.

[0038] The disengager 5 comprises an outer connecting sleeve 51, the outer connecting sleeve 51 is fixedly connected to the outside of the output end of the motor 1, the outside of the outer connecting sleeve 51 is provided with a spiral connecting belt 52, the outside of the spiral connecting belt 52 is respectively inserted with a first pin 53 and a second pin 59, the second pin 59 is inserted into the inside of the outer connecting sleeve 51, the bottom of the first pin 53 is inserted with an inner threaded sleeve 56, the outside of the spiral connecting belt 52 is threadedly connected with a bolt 54, the bolt 54 penetrates through the bottom of the spiral connecting belt 52 and is threadedly connected with the inner threaded sleeve 56, the outer end surface of the spiral connecting belt 52 is fixedly connected with an elastic strip 55, the inner threaded sleeve 56 is rotationally connected to the outside of the granulator 3, the threaded part in the inside of the inner threaded sleeve 56 is threadedly connected with the output end of the motor 1, the non-threaded part in the inside of the inner threaded sleeve 56 is fixedly connected with a double connecting table 57, the double connecting table 57 is rotationally connected to the outside of the granulator 3, the end of the double connecting table 57 away from the motor 1 is fixedly connected with a rotating shaft 58, and the outside of the rotating shaft 58 is fixedly connected with the granulator 3.

[0039] By starting the motor 1, the outer connecting sleeve 51 connected with the output end of the motor 1 will rotate, the spiral connecting belt 52 is locked on the outer connecting sleeve 51 through the second pin 59, and the other half of the spiral connecting belt 52 is retracted on the inner threaded sleeve 56 through the first pin 53, so that the inner threaded sleeve 56 will rotate with the outer connecting sleeve 51, wherein the inside of the inner threaded sleeve 56 is threadedly connected with the output end of the motor 1, and the output end of the motor 1 has a tendency to rotate outward along the inner threaded sleeve 56, but the outer connecting sleeve 51 fixedly connected with the output end of the motor 1 is connected with the inner threaded sleeve 56 through the spiral connecting belt 52, so that the tendency of the motor 1 to rotate outward is locked to achieve the effect of transmitting the rotating force.

[0040] The inner threaded sleeve 56 is rotationally connected to the outside of the outer roller shell 31, and the inside of the inner threaded sleeve 56 is fixedly connected with the double connecting table 57, and the other end of the double connecting table 57 is connected with the rotating shaft 58, so that the rotation of the rotating shaft 58 drives the granulator 3 to work.

[0041] Because a large number of wood chips always contain iron filings or hard impurities, the pelletizer 3 cannot grind them. If enough iron filings and hard impurities accumulate in a certain part of the pelletizer 3, the pellet assembly 33 inside the pelletizer 3 will get stuck. Since the motor 1 is still running and the shaft 58 stops rotating due to the iron filings, the output end of the motor 1 will move relative to the inner threaded sleeve 56. Through the torsional force on the output end of the motor 1 and the stopping of the inner threaded sleeve 56, the spiral connecting belt 52 will be subjected to the combined force of the two, thereby popping out the second pin 59 and the first pin 53 that were originally inserted into the outer connecting sleeve 51 and the inner threaded sleeve 56 from inside the former two. The surfaces of the first pin 53 and the second pin 59 that contact the interior of the former two are curved surfaces, which eventually causes the outer connecting sleeve 51 to disengage from the spiral connecting belt 52, so that the output end of the motor 1 rotates out from inside the inner threaded sleeve 56, thereby removing the driving force, stopping the pelletizer 3 and protecting it from being hooked.

[0042] The spiral connecting band 52 is threaded with a bolt 54 on the side near the internal threaded sleeve 56. The bolt 54 serves to fix the spiral connecting band 52 to the internal threaded sleeve 56, and the bolt 54 will not fall off even if the above-mentioned jamming problem occurs.

[0043] Second embodiment, such as Figures 5-10 As shown, the pelletizer 3 includes an outer roller shell 31. The bottom of the outer roller shell 31 is fixedly connected to the support plate 4.

[0044] As the rotating shaft 58 rotates, the triangular turntable 32 fixedly connected to its outer side rotates. A particle assembly 33 is also sleeved on the outer side of the triangular turntable 32. The particle assembly 33 is locked to the triangular turntable 32 by a fixing assembly 34. A chip pressing plate 36 is also fixedly connected to the outer side of the triangular turntable 32. The chip pressing plate 36 is shaped to be almost attached to the outer side of the forming rack 35, so as to spread the wood chips evenly on the forming rack 35, allowing the particle assembly 33, which rotates behind it, to evenly form the wood chips into particles.

[0045] The particle assembly 33 includes a clamping rod 331 sleeved outside the triangular turntable 32, both ends of the clamping rod 331 are provided with a fixing assembly 34, the outer side of the clamping rod 331 is rotationally connected with a connecting shaft 332, the side away from the clamping rod 331 of the connecting shaft 332 is extrudedly provided with a press 333, the inner side of the press 333 is fixedly connected with a protective sleeve 334, the outer side of the protective sleeve 334 is inserted with a stabilizer 335, the stabilizer 335 penetrates outside the outer roller shell 31, and the top of the stabilizer 335 is communicated with a force relief bag 336.

[0046] The stabilizer 335 includes a top strip 3351 penetrating outside the outer roller shell 31 and the protective sleeve 334 respectively, the bottom of the top strip 3351 is fixedly connected with a support plate 3352, the bottom of the support plate 3352 is fixedly connected with a fixing block 3357, the fixing block 3357 is extrudedly matched with the connecting shaft 332, the outer side of the support plate 3352 is fixedly connected with a bent shaft 3353, the outer side of the bent shaft 3353 is rotationally connected with a flexible plate 3354, the outer side of the flexible plate 3354 is fixedly connected with a spring 3355, one end of the spring 3355 away from the flexible plate 3354 is fixedly connected with an abutting plate 3356, and the top of the abutting plate 3356 is extrudedly matched with the bottom of the protective sleeve 334.

[0047] When the outer side of the press 333 is blocked by iron filings or hard impurities between the press 333 and the forming rack 35, the press 333 will vibrate violently due to the blockage extrusion, at this time, the stabilizer 335 originally outside the outer roller shell 31 will extend into the inner side of the outer roller shell 31, the stabilizer 335 is symmetrically arranged on both ends of the forming rack 35, the stabilizer 335 includes the top strip 3351, the bottom of the top strip 3351 is fixedly connected with the support plate 3352, the outer side of the support plate 3352 is fixedly connected with the bent shaft 3353, the bottom of the support plate 3352 is fixedly connected with the fixing block 3357, the outer side of the bent shaft 3353 is rotationally connected with the flexible plate 3354, and the upper side of the flexible plate 3354 is fixedly connected with the abutting plate 3356 through the spring 3355.

[0048] Wherein the fixed block 3357 is magnetic, and the top strip 3351 is frictionally connected with the outer roller shell 31, so that when the press 333 is not stuck, the top strip 3351 is outside the outer roller shell 31, but when the press 333 is stuck, it will vibrate violently inside the outer roller shell 31, at this time the top strip 3351 will extend into it, and then the fixed block 3357 will generate a magnetic repulsion to the press 333, so that the extrusion part between the press 333 and the iron filings will shake, so that the iron filings that were extruded together will be loose, thereby restoring the press 333 to a rotating state. Wherein the above disengager 5 will only occur when the fixed block 3357 cannot loosen the iron filings or the loosening time is too long.

[0049] In addition, sometimes the top strip 3351 will be inserted into the protective sleeve 334, and the flexible plate 3354 rotatably connected to the outside of the curved shaft 3353 will be compressed by passing through the protective sleeve 334, and then the flexible plate 3354 below the protective sleeve 334 will expand to both sides due to the re-lengthening of the spring 3355, at this time the flexible plate 3354 will be clamped below the protective sleeve 334 to limit the protective sleeve 334, thereby reducing the wear between the press 333 and the iron filings.

[0050] The press 333 comprises a press roller 3331, the inside of the press roller 3331 is fixedly connected with the protective sleeve 334, the side of the protective sleeve 334 is provided with a bearing 3332, the bearing 3332 is fixedly connected inside the press roller 3331, the inside of the bearing 3332 is extruded and matched with the connecting shaft 332, the inside of the press roller 3331 at the center is fixedly connected with a hollow frame 3333, the bottom of the hollow frame 3333 is fixedly connected with a semicircular cross rod 3334, the inside of the semicircular cross rod 3334 is inserted with a swing plate 3335, the inside of the swing plate 3335 is rotatably connected with a support rod 3336, both ends of the support rod 3336 are fixedly connected inside the press roller 3331, the bottom of the swing plate 3335 is fixedly connected with a balance rod 3337.

[0051] Because the connecting shaft 332 will produce wear between the protective sleeve 334 and the bearing 3332, and then the connecting shaft 332 will shake and hit the balance rod 3337, the top of the balance rod 3337 is connected with the swing plate 3335, and the swing plate 3335 rotates through the support rod 3336, and the swing plate 3335 originally inserted in the semicircular cross rod 3334 will be pulled out, so that the hollow frame 3333 and the connecting shaft 332 will be connected with each other, and the filler remaining in the hollow frame 3333 will be coated on the connecting shaft 332, to fill the cracks on the connecting shaft 332 due to wear.

[0054] When the pressure grinding tooth 3312 is extruded by iron filings or other hard impurities, the pressure grinding tooth 3312 will have a tendency to move into the inner roller 3311, wherein the bottom of the pressure grinding tooth 3312 is fixedly connected with a first magnetic block 3313, and the first magnetic block 3313 is in repulsive relationship with a second magnetic block 3315 fixedly connected to the inner side of the inner roller 3311, and the pressure grinding tooth 3312 will not be bounced out of the inner side of the inner roller 3311 due to the repulsive force, and the telescopic rod 3314 fixedly connected to the bottom of the pressure grinding tooth 3312 plays a role in stable movement. Therefore, the pressure grinding tooth 3312 extruded by iron filings will shrink into the inner roller 3311 correspondingly, so as to reduce the degree of surface wear of the pressure grinding tooth 3312.

[0055] As the pressure grinding teeth 3312 moves downward along the pressing plate 3164 in the process of entering the inner roller 3311, when the pressure grinding teeth 3312 surface contacts more iron filings, the orientation of the force of the pressure grinding teeth 3312 on the pressing plate 3164 changes, causing the pressing plate 3164 to move inward, and the pressing plate 3164 is connected to the first connecting rod 3165, and the other end of the first connecting rod 3165 is connected to the first connecting seat 3166, causing the first connecting seat 3166 to move the buffer rod 3167 inward, wherein the buffer rod 3167 functions to buffer the external force, and the other end of the buffer rod 3167 is connected to the second connecting seat 3168, so the second connecting seat 3168 can extrude the capsule 1601, wherein the capsule 1601 contains a non-Newtonian fluid, so the extruded capsule 1601 forms a rigid material to counteract the extrusion force caused by the pressure grinding teeth 3312 and eliminate the force.

[0056] The ductile bar 3160 is ductile and bends when extruded by the dowel 3163, and when the extrusion force of the pressure grinding teeth 3312 is large, the bending radius of the ductile bar 3160 increases, and the outer side of the ductile bar 3160 is fixedly connected to the second connecting rod 3169, and the second connecting rod 3169 is also connected to the second connecting seat 3168, so the bent ductile bar 3160 drives the second connecting seat 3168 to increase the extrusion of the capsule 1601, thereby combining the external force in one direction to eliminate the force as a whole.
