Description

Technical Field

[0001] This invention belongs to the field of soil conditioner granulation production technology, and in particular relates to a soil conditioner production device that does not require deep tillage. Background Technology

[0002] The core of the processing technology for granular no-till soil conditioner is raw material pretreatment → mixing and homogenization → granulation → drying and curing → screening and grading → finished product packaging. The key is to balance particle strength (to prevent breakage) and disintegration (to take effect quickly after entering the soil) to suit the no-till application scenario.

[0003] Disc granulators are the mainstream equipment for small and medium-scale pellet production (such as soil conditioners and organic fertilizers), and their core advantage is high cost-effectiveness.

[0004] Because the disc of a disc granulator is tilted, its operational defects are quite obvious. For example, when granulating no-till soil conditioners, material is prone to being ejected from the disc. The reasons for this material ejection are as follows:

[0005] First, frequent start-stop cycles of the disc granulator can cause uneven force on the material inside the disc, making it easy for the material to be thrown out at the moment of startup. Second, excessive accumulation of material on the wall can lead to uneven material layer thickness, causing localized material overflow. Third, inaccurate manual angle adjustment can result in insufficient gravitational force on the material, making it easy for it to be thrown out by centrifugal force; while an angle that is too small (below 40°) can cause excessive material accumulation, which in turn increases the risk of overflow.

[0006] Although there are designs to prevent material throwing in disc granulators, the existing designs either install symmetrically movable cover plates on the disc to cover the disc opening, which achieves the design to prevent material throwing, but because the disc opening is completely covered, it is difficult for personnel to observe the quality of the formed particles inside the disc, which in turn affects the granulation efficiency and granulation quality of the disc granulator for no-till soil conditioner. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] This invention relates to a soil conditioner production device that requires no deep tillage, comprising a frame, a base plate rotatably mounted on the frame, and a granulation disc mounted on the base plate and capable of rotation; it also includes irregularly shaped bending rods symmetrically mounted on both sides of the base plate, with their free ends extending to the outer side of the outer ring surface of the granulation disc; an arc-shaped plate symmetrically and movably mounted on the lower outer ring surface of the granulation disc; an arc-shaped baffle bent into shape on the top of the arc-shaped plate, and the arc-shaped baffle movably fitting against the outer opening of the granulation disc; and a drive support mechanism, consisting of two sets respectively mounted on the free ends of the irregularly shaped bending rods, for driving the arc-shaped baffle to move circumferentially around the outer opening of the granulation disc.

[0009] Furthermore, the drive support mechanism includes a protective box mounted on the free end of the irregularly shaped bent rod for mounting a motor; a gear mounted on the output shaft of the motor, with the gear located outside the protective box; an arc-shaped rack mounted on the outer ring surface of the arc-shaped plate, meshing with the gear; an arc-shaped square frame strip mounted on the side of the protective box near the arc-shaped plate, with the length of the arc-shaped square frame strip being greater than half the total length of the arc-shaped plate; and a guide rail slide, which is fixed on the outer ring surface of the arc-shaped plate and movably mounted in the guide groove of the arc-shaped square frame strip, with both ends of the guide groove being open.

[0010] Furthermore, the drive support mechanism also includes a connecting column fixed to the end of the guide rail slide near the gear component and a limiting block mounted on the connecting column; the size of the limiting block is larger than the groove size of the guide slide.

[0011] Furthermore, a support and locking assembly is provided on the arc-shaped frame strip. The support and locking assembly includes a support plate installed on the outer side of the arc-shaped frame strip away from the protective box; an electric push rod installed on the support plate with its output rod facing the arc-shaped rack; a support block installed on the end of the support plate near the arc-shaped rack; a shaft rotatably installed on the support block with its rod extending to the outside of the teeth of the arc-shaped rack; a guide gear fixedly installed on the extended end of the shaft and meshing with the arc-shaped rack; and a locking assembly installed on the support block to connect the shaft and the output rod of the electric push rod.

[0012] Furthermore, the locking assembly further includes: a guide blind hole, formed on the side of the support block near the electric push rod, and the guide blind hole communicates with the end of the shaft mounted on the support block; a mating hole, formed on the end of the shaft located at the bottom of the guide blind hole; a push plate, mounted on the side wall of the support block near the electric push rod, and aligned with the guide blind hole; a mating block, mounted on the push plate, located inside the guide blind hole, and the mating block and the mating hole cooperate with each other; and a spring member, the two ends of which are respectively connected to the push plate and the side wall of the support block.

[0013] Furthermore, the guide blind hole, the mating hole, and the mating block are all the same size and have polygonal cross-sections. The length of the mating block is greater than the depth of the guide blind hole.

[0014] Furthermore, the base plate is equipped with a power unit for driving the granulation disc to rotate, and the base plate and the frame are connected by an angle-adjusting screw rod.

[0015] Furthermore, a portal frame is installed on the base plate, and a connecting rod is detachably mounted on the crossbeam of the portal frame, with a scraper mounted on the end of the connecting rod near the granulation disc.

[0016] The present invention has the following beneficial effects:

[0017] This solution, through the combination of a drive support mechanism and symmetrical arc-shaped baffles, has the following beneficial effects:

[0018] Firstly, when the drive support mechanism is working, it can drive the symmetrical arc plate to move, so that the symmetrical arc baffle blocks the lower opening of the granulation disc, preventing a large amount of mixed material from being thrown out of the lower opening of the granulation disc when it rotates.

[0019] The drive support mechanism can support the arc plate and the arc baffle, so that the arc plate is close to the outer ring surface of the granulation disk in a close fit state. Then, without interfering with the normal rotation of the granulation disk, the bent arc baffle can be accurately fitted to the lower opening of the granulation disk to block the lower opening of the granulation disk.

[0020] Secondly, the size of the "discharge gap" formed by the opening of the symmetrical arc-shaped baffles can be adjusted, so that the two arc-shaped baffles that are far apart from each other do not affect the normal discharge of the formed particles from the granulation disc, and can continue to granulate the mixture in the granulation disc normally.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] Please see Figures 1-8 As shown, please refer to the following for details. Figure 1 and Figure 2 As shown, the present invention is a soil conditioner production device that does not require deep tillage, including a frame 1, a base plate 2 rotatably mounted on the frame 1, and a granulation disc 3 mounted on the base plate 2 and capable of rotation; it also includes irregularly shaped bending rods 4, symmetrically mounted on both sides of the base plate 2, with their free ends extending to the outer side of the outer ring surface of the granulation disc 3; an arc-shaped plate 5, symmetrically and movably mounted on the lower outer ring surface of the granulation disc 3; an arc-shaped baffle 51, bent into shape on the top of the arc-shaped plate 5, and the arc-shaped baffle 51 movably fitting against the outer opening of the granulation disc 3; and a drive support mechanism 6, two sets of which are respectively mounted on the free ends of the irregularly shaped bending rods 4, for driving the arc-shaped baffle 51 to move circumferentially around the outer opening of the granulation disc 3;

[0043] The base plate 2 is equipped with a power unit for driving the granulation disc 3 to rotate. The base plate 2 and the frame 1 are connected by an angle-adjusting screw rod 8. A portal frame 9 is installed on the base plate 2, and a connecting rod 91 is detachably installed on the crossbeam of the portal frame 9. A scraper 92 is installed on the end of the connecting rod 91 near the granulation disc 3.

[0044] It should be further explained that the specific connection method between the angle adjusting screw rod 8 and the base plate 2 and the frame 1 in this scheme is as follows: an adjusting lug is installed on the base plate 2 near the rear side, and an adjusting lug is also installed on the crossbeam on the rear side of the frame 1. The two adjusting lugs are connected to each other through the angle adjusting screw rod 8. By rotating the nut on the angle adjusting screw rod 8, the two adjusting lugs can be moved closer or further apart, which can adjust the angle between the base plate 2 and the horizontal plane. In this way, the angle between the rotation axis of the granulation disc 3 and the horizontal plane can be adjusted according to the actual working conditions.

[0045] In a preferred embodiment of this solution, when the two arc-shaped plates 5 are attached to each other at the inclined lower opening of the granulation disc 3, the total arc length of the two is less than half the diameter of the granulation disc 3. Therefore, when the two arc-shaped plates 5 drive the two arc-shaped baffles 51 to move away from each other to the maximum extent, they will not rise to the top of the granulation disc 3, thus not affecting the disassembly and replacement of the arc-shaped plates 5 and the arc-shaped baffles 51. The radial dimension of the part attached to the opening of the granulation disc 3 is less than the radius of the granulation disc 3, which can block the material gathered at the lower part of the opening of the granulation disc 3 to prevent material from being thrown out, without interfering with the normal observation of the forming state and quality of the soil conditioner particles in the granulation disc 3, and facilitating the accurate discharge and collection of the soil conditioner particles made in the granulation disc 3. The power unit is assembled from a reducer and an electric motor, and the specific assembly method refers to the assembly of existing disc granulators.

[0046] The process of producing granules from no-till soil conditioner using the disc granulator in this solution is as follows:

[0047] The first step is raw material processing: The core raw materials (such as humic acid, amino acids, mineral powder, and biological agent carrier) are pulverized to 80-120 mesh, and coarse fibrous materials (such as straw powder) need to be pulverized to 60 mesh or higher to avoid large particles affecting granulation uniformity and soil dispersibility. Then, in a mixer (such as a twin-shaft paddle mixer or ribbon mixer), first add the mineral-based raw materials (such as zeolite powder and bentonite) and the pulverized core raw materials and coarse fibrous materials, and dry mix for 5-8 minutes. Then, slowly add the liquid components (such as amino acid liquid and binder), and wet mix for 3-5 minutes, ensuring that the overall uniformity error of the material is ≤3%, to obtain the mixed raw materials to be granulated.

[0048] The second step is to block the lower opening of the granulation disc 3: Since the initial position of the two symmetrical arc plates 5 is in a separated state (far from the lower opening of the granulation disc 3), the operator controls the two sets of drive support mechanisms 6 installed by the two irregular bending rods 4 to work synchronously through a handheld controller, so that the two arc plates 5 move closer to each other. When the two arc plates 5 move to a state of mutual contact, the two symmetrically contacted arc baffles 51 can move and contact the lower opening of the granulation disc 3 in a parallel state with the bottom of the disc, thus blocking the outer edge of the lower opening of the granulation disc 3.

[0049] The third step is granulation: After the arc-shaped baffle 51 is in place, the operator can manually or mechanically feed the material (such as an inclined screw conveyor or conveyor belt) into the granulation disc 3 through the upper opening. Then, the power unit installed on the bottom plate 2 is controlled to drive the granulation disc 3 to rotate at a constant speed. Alternatively, the mixed material can be fed into the disc granulator while the granulation disc 3 is rotating at a constant speed. When the granulation disc 3 is rotating at a constant speed, the scraper 92 installed on the gantry frame 9 through the connecting rod 91 can make the fed mixed material uniformly form soil conditioner granules in the granulation disc 3. Since the lower opening of the granulation disc 3 is in contact with the arc-shaped baffle 51, the granulation disc 3 can effectively reduce the phenomenon of material throwing caused by the mixed material gathered at the lower opening when it starts up or accelerates.

[0050] Step 4, disc discharge: When the operator observes that a large number of soil conditioner granules have formed near the lower opening of the granulation disc 3, the operator controls the drive support mechanism 6 through the handheld controller to drive the two arc-shaped plates 5 to move away from each other. At this time, the operator can control the size of the "discharge port" formed between the two arc-shaped baffles 51 after they move away from each other according to the amount of soil conditioner granules formed in the granulation disc 3. This ensures that the two arc-shaped baffles 51 do not affect the normal discharge of the formed granules from the granulation disc 3, and can continue to granulate the mixture in the granulation disc 3.

[0051] This solution, through the cooperation of the drive support mechanism 6 and the symmetrical arc-shaped baffle 51, has the following beneficial effects:

[0052] First, when the drive support mechanism 6 is working, it can drive the symmetrical arc plate 5 to move, so that the symmetrical arc baffle 51 blocks the lower opening of the granulation disc 3, preventing a large amount of mixed material from being thrown out from the lower opening of the granulation disc 3 when the granulation disc 3 is rotating.

[0053] The drive support mechanism 6 can support the arc plate 5 and the arc baffle 51, so that the arc plate 5 is close to the outer ring surface of the granulation disk 3 in a close fit state. Then, without interfering with the normal rotation of the granulation disk 3, the bent arc baffle 51 can be accurately fitted to the lower opening of the granulation disk 3 to block the lower opening of the granulation disk 3.

[0054] Secondly, the size of the "discharge gap" formed by the opening of the symmetrical arc-shaped baffles 51 can be adjusted so that the two arc-shaped baffles 51 that are far apart from each other do not affect the normal discharge of the formed particles from the granulation disc 3, and can continue to granulate the mixture in the granulation disc 3 normally.

[0055] See Figure 3 and Figure 4 As shown, the drive support mechanism 6 includes a protective box 61, installed on the free end of the irregularly shaped bent rod 4, for mounting a motor; a gear 62, installed on the output shaft of the motor, and located outside the protective box 61; an arc-shaped rack 63, installed on the outer ring surface of the arc plate 5, and meshing with the gear 62; an arc-shaped square frame 64, installed on the side of the protective box 61 near the arc plate 5, and the length of the arc-shaped square frame 64 is greater than half the total length of the arc plate 5; and a guide rail slide 65, which is fixed on the outer ring surface of the arc plate 5 and movably installed in the guide groove 641 of the arc-shaped square frame 64, the two ends of the guide groove 641 being open.

[0056] As a preferred embodiment of this solution, the motor and gear 62 are installed on both sides of the non-center of the lower opening of the granulation disc 3. The meshing of the gear 62 and the arc-shaped rack 63 can maximize the contact between the symmetrical arc-shaped baffles 51, so as to accurately block the material put into the granulation disc 3, and maximize the distance between the arc-shaped baffles 51, so that the size of the "discharge port" formed between them is controllable, which facilitates the accurate discharge of the granulated soil conditioner particles.

[0057] The irregular bending rod 4 is connected to the rotating shafts on both sides of the bottom plate 2. Thus, when the granulation disc 3 is adjusted at an angle, the drive support mechanism 6 can drive the arc plate 5 and the arc baffle 51 to adjust their angles synchronously, so that the symmetrical arc baffle 51 can accurately block the lower opening of the granulation disc 3 at different angles.

[0058] The specific operation of the drive support mechanism 6 in this scheme is as follows:

[0059] When it is necessary to drive the symmetrical arc-shaped baffles 51 to fit together, the operator controls the servo motor fixed in the protective box 61 to work through the handheld controller, so that it drives the gear 62 to rotate. Then the arc-shaped rack 63 will drive the arc-shaped plate 5 to slide on the outer ring surface of the granulation disk 3, so that the symmetrical arc-shaped baffles 51 can fit together and be located on the outer side of the lower opening of the granulation disk 3, thereby blocking the material put into the granulation disk 3.

[0060] The servo motor is controlled to rotate in the opposite direction, so that the gear 62 and the arc rack 63 mesh, driving the fitted arc baffle 51 to move away from each other, thereby opening the arc baffle 51 that is blocking the lower opening of the granulation disc 3.

[0061] Since the protective box 61 is fixed with an arc-shaped square frame strip 64 arranged along the arc length direction of the arc plate 5, and the guide rail slide strip 65 fixed on the outer side of the arc plate 5 is slidably arranged in the guide slide groove 641 with open ends, when the gear 62 and the arc rack 63 mesh and drive, causing the symmetrical arc plate 5 to slide, the cooperation of the guide rail slide strip 65 and the arc-shaped square frame strip 64 can not only play an arc-shaped guiding role for the sliding arc plate 5, but also, because the length of the arc-shaped square frame strip 64 is greater than half of the total length of the arc plate 5, the cooperation of the guide rail slide strip 65 and the arc-shaped square frame strip 64 can also play a gravity support role for the arc plate 5 and the arc baffle 51, preventing the symmetrical arc plate 5 and the arc baffle 51 from falling down due to the lack of gravity support components when they are close to or far apart, thus failing to block the mixing material from the outer side of the lower opening of the granulation disc 3.

[0062] See Figure 3 and Figure 4 As shown, the drive support mechanism 6 also includes a connecting column 66 fixed to the end of the guide rail slide 65 near the gear component 62 and a limiting block 67 mounted on the connecting column 66; the size of the limiting block 67 is larger than the slot size of the guide slide groove 641.

[0063] As a preferred embodiment of this solution, in order to avoid the two mutually attached arc-shaped plates 5 slipping excessively and causing impact damage;

[0064] The connecting post 66 and the limiting block 67 are installed on the side of the guide rail slide 65 away from the side of the arc plate 5. Therefore, when the symmetrical arc plates 5 slide close to each other, the guide rail slide 65 will slide in the guide groove 641, while the connecting post 66 and the limiting block 67 will slide towards the opening of the guide groove 641. When the symmetrical arc plates 5 move to the mating state, the limiting block 67 will be exactly mated to the opening of the guide groove 641. At this time, the limiting block 67 and the opening of the guide groove 641 are mated, which can limit the sliding of the guide rail slide 65 through the connecting post 66. This facilitates the limiting of the arc plates 5 after they are mated, and prevents the symmetrical arc plates 5 from being damaged by impact when they are mated because the operator did not stop the servo motor in time.

[0065] See Figure 6 and Figure 7As shown, a support and locking assembly 7 is provided on the arc-shaped square frame 64. The support and locking assembly 7 includes: a support plate 71, which is installed on the outer side of the arc-shaped square frame 64 away from the protective box 61; an electric push rod 72, which is installed on the support plate 71 and whose output rod faces the arc-shaped rack 63; a support block 73, which is installed on the end of the support plate 71 near the arc-shaped rack 63; a shaft 74, which is rotatably installed on the support block 73 and whose rod extends to the outside of the teeth of the arc-shaped rack 63; a guide gear 75, which is fixedly installed on the extended end of the shaft 74 and meshes with the arc-shaped rack 63; and a locking assembly, which is installed on the support block 73 and connects the shaft 74 and the output rod of the electric push rod 72.

[0066] As a preferred embodiment of this solution, regardless of whether the symmetrical arc plates 5 are in a state of mutual contact or distance, only the servo motor locks the gear component 62. Then, the engagement of the gear component 62 and the arc rack 63 is used to lock the arc plate 5 in a stationary state. Obviously, when the granulation disk 3 is rotating, it will inevitably generate a certain rotational friction force on the arc plate 5 and the arc baffle 51. This friction force will then be transmitted through the arc rack 63 to the gear component 62, causing wear on the teeth of the gear component 62 or the arc rack 63.

[0067] Therefore, this design is such that when the gear 62 rotates, causing the arc rack 63 to slide the arc plate 5, the output rod of the electric push rod 72 is in a retracted state, and the locking component disengages from the shaft 74. At this time, the shaft 74 will rotate on the support block 73 through the bearing. Then, when the arc plate 5 moves, the meshing of the guide gear 75 and the arc rack 63 can guide and support the sliding arc plate 5, preventing the arc plates 5 from getting too close to each other. In this case, the arc plate 5 only has the cooperation of the guide rail slide 65 and the arc square frame 64, and cannot accurately support and guide the sliding arc plate 5 and the arc baffle 51.

[0068] When the symmetrical arc plate 5 is stationary, the operator controls the output rod of the electric push rod 72 to extend through the handheld controller, causing it to push the locking component to move into the support block 73. At this time, the locking component can lock and limit the shaft 74, preventing the shaft 74 from rotating on the support block 73. This allows the guide gear 75, which is in a locked state, to perform circumferential limiting locking on the arc rack 63. This prevents the arc plate 5 and the arc baffle 51 from being locked in the circumferential direction by the meshing of the gear 62 and the arc rack 63 by the servo motor in a self-locking state. Consequently, when the arc plate 5 and the arc baffle 51 are subjected to the rotational friction force of the granulation disk 3 for a long time, wear phenomena may occur in the arc rack 63 and the gear 62, or the arc plate 5 and the arc baffle 51 may slip freely.

[0069] See Figure 6 and Figure 7 As shown, the locking assembly further includes: a guide blind hole 731, which is formed on the side of the support block 73 near the electric push rod 72, and the guide blind hole 731 communicates with the end of the shaft 74 mounted on the support block 73; a mating insertion hole 741, which is formed at the end of the shaft 74 located at the bottom of the guide blind hole 731; a push plate 76, which is mounted on the side wall of the support block 73 near the electric push rod 72 and aligned with the guide blind hole 731; a mating insertion block 77, which is mounted on the push plate 76 and located inside the guide blind hole 731; and a spring member 78, the two ends of which are respectively connected to the push plate 76 and the side wall of the support block 73.

[0070] As a preferred embodiment of this solution, when the shaft 74 needs to rotate on the support block 73, the output rod of the electric push rod 72 is retracted to disengage it from the push plate 76. At this time, the spring 78 is in the extended state, and the push plate 76 will drive the docking block 77 to disengage from the docking hole 741, so that the shaft 74 can rotate on the support block 73 without affecting the meshing of the guide gear 75 and the arc rack 63, thereby achieving the guiding support of the arc plate 5.

[0071] When it is necessary to lock the shaft 74 onto the support block 73, the guide gear 75, which is in a locked state, can lock and limit the arc rack 63. At this time, the output rod of the control electric push rod 72 extends, causing it to push the push plate 76 towards the opening of the guide blind hole 731. At this time, the connected spring 78 will be compressed, and the moving push plate 76 will drive the mating block 77 to move in the guide blind hole 731 and insert into the mating hole 741 to lock the shaft 74, so that the shaft 74 will not rotate on the support block 73, thereby achieving the locking of the guide gear 75.

[0072] When the output rod of the electric push rod 72 is retracted, the push plate 76 will slide away from the support block 73 under the elastic restoring force of the spring 78. This will cause the mating block 77 to disengage from the mating hole 741, but will not disengage from the guide blind hole 731. This will make it easier for the mating block 77 to be accurately inserted back into the mating hole 741, thereby locking and limiting the shaft 74.

[0073] Furthermore, the guide blind hole 731, the docking hole 741, and the docking block 77 are all the same size and have a polygonal cross-section. The length of the docking block 77 is greater than the depth of the guide blind hole 731.

[0074] As a preferred embodiment of this solution, the guide blind hole 731, the docking hole 741, and the docking block 77 are all designed with the same size, so that when part of the docking block 77 is inserted into the docking hole 741, the other part of the docking block 77 will remain in the guide blind hole 731, which facilitates locking and limiting the shaft 74. Furthermore, the torsional force of the shaft 74 on the docking block 77 will be directly applied to the support block 73 rather than to the push plate 76, thereby improving the locking and limiting effect of the docking block 77 on the shaft 74.

[0075] Similarly, the cross-sections of the guide blind hole 731, the docking hole 741, and the docking block 77 are all designed as regular polygons, preferably regular hexagons or larger. This allows the docking block 77 to be accurately and quickly inserted into the aligned docking hole 741 when the shaft 74 is rotated to any position and stops. Even if there is misalignment between the regular polygon docking hole 741 and the docking block 77, as the number of regular polygons increases, the fine-tuning rotation angle of the shaft 74 will be smaller, thus not affecting the accurate fit of the symmetrical arc plates 5 after the sliding stops.

[0076] The length of the mating block 77 is greater than the depth of the guide blind hole 731, so that it will not affect the accurate insertion of the mating block 77 into the mating hole 741. At the same time, it will not cause the mating block 77 to completely detach from the guide blind hole 731 after it detaches from the mating hole 741. Therefore, it will not affect the push plate 76 from pushing the mating block 77 to accurately insert it into the mating hole 741 again.

[0077] It should be further explained that when the symmetrical arc plates 5 are fitted together, the mating hole 741 on the shaft 74 and the mating block 77 are in a positive alignment state, and there is no need to make any further fine-tuning to the shaft 74.

[0078] The symmetrical drive support mechanism 6 and the symmetrical support locking assembly 7 are installed at the position of the granulation disc 3. The rotation speed and angle adjustment of the granulation disc 3, the precision of the mutual contact between the drive support mechanism 6 and the symmetrical arc plate 5 and arc baffle 51, and the size of the "discharge port" formed after their separation are all data parameters that are debugged and processed before the equipment leaves the factory, so that the disc granulator of this solution can be used normally after leaving the factory.
