DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figure 1-Figure 8The invention discloses an energy-saving grinding device for processing fertilizer raw materials, comprising a frame 1, a grinding cylinder 2 and a hopper 3 are fixedly mounted on the frame 1, the hopper 3 is arranged at the upper end of the grinding cylinder 2, an upper grinding disc 4 is arranged inside the grinding cylinder 2, the upper grinding disc 4 is fixedly mounted at the bottom end of the hopper 3, and a dynamic grinding mechanism 5 is arranged below the upper grinding disc 4; the dynamic grinding mechanism 5 comprises a mounting frame 51, the mounting frame 51 is fixedly connected to the grinding cylinder 2, a movable rod 52 is movably inserted on the mounting frame 51, and a lower grinding disc 53 is fixedly mounted on the upper end of the movable rod 52, and the raw materials are moved between the upper grinding disc 4 and the lower grinding disc 53. The grinding discs 53 are ground, and a rotating drive component 54 is provided at the bottom of the grinding cylinder 2. The rotating drive component 54 is used to drive the movable rod 52 and the lower grinding disc 53 to rotate. The dynamic grinding mechanism 5 also includes a driving assembly 55. The driving assembly 55 is used to drive the movable rod 52 and the lower grinding disc 53 to move vertically; a discharge port 21 is provided on one side of the grinding cylinder 2, and an air inlet 22 is provided on one side of the upper end of the grinding cylinder 2. The air inlet 22 points to the position between the upper grinding disc 4 and the lower grinding disc 53. A fan 6 is installed on the frame 1, and the output end of the fan 6 is connected to the air inlet 22.

[0030] It should be noted that the rotating drive component 54 can be a motor, and the output shaft of the motor is vertically slidably connected to the movable rod 52 through internal and external splines, so that while the rotating drive component 54 drives the movable rod 52 and the lower grinding disc 53 to rotate, the movable rod 52 can also move in the vertical direction relative to the output shaft of the motor.

[0031] In the above technical solution, if Figure 3-Figure 6 As shown, the driving assembly 55 includes a cylinder 551, which is fixedly mounted on the bottom of the lower grinding disc 53. The inner surface of the lower end of the cylinder 551 has a conical surface 5511. Both ends of the mounting frame 51 are slidably connected with sliders 553. The front end of the slider 553 is rotatably mounted with a ball 554, and the ball 554 is in contact with the conical surface 5511.

[0032] Furthermore, a movable sleeve 552 is provided on the outer side of the movable rod 52, and the upper end of the movable sleeve 552 is rotatably connected to a turntable 556. Connecting rods 555 are provided between the two sliders 553 and the turntable 556. The two ends of the connecting rod 555 are respectively hinged to the sliders 553 and the turntable 556. An elastic component 550 is provided on the outer side of the movable rod 52, and the two ends of the elastic component 550 are respectively pressed with the lower grinding disc 53 and the mounting frame 51. The driving assembly 55 also includes a component for driving the movable sleeve 552 to move vertically.

[0033] Furthermore, the component for driving the movable sleeve 552 to move vertically includes a linear driving component 558, which is fixedly installed at the bottom of the grinding cylinder 2. A lever 557 is fixedly installed at the output end of the linear driving component 558. An annular groove 5521 is opened on the outer side of the movable sleeve 552, and the lever 557 is movably inserted into the inner side of the annular groove 5521.

[0034] It should be noted that the elastic component 1 550 is a compression spring. In order to avoid friction between the compression spring and the bottom of the lower grinding disc 53 when the lower grinding disc 53 rotates, a disc can be rotatably installed at the bottom of the lower grinding disc 53, and then the upper end of the compression spring can be pressed on the disc. The linear drive component 558 adopts a cylinder, which drives the movable sleeve 552 to move vertically by pushing the lever 557. The lever 557 is Y-shaped and inserted into the movable sleeve 552, so that the lever 557 is not affected when the movable sleeve 552 rotates.

[0035] In this embodiment, the implementation method is as follows: when grinding fertilizer raw materials such as bone meal, the movable rod 52 is driven to rotate by the rotating driving component 54, and the movable rod 52 drives the lower grinding disc 53 to rotate. At this time, the movable sleeve 552 also rotates together, and the crushed fertilizer raw materials are added from the hopper 3. The fertilizer raw materials enter between the upper grinding disc 4 and the lower grinding disc 53 from the bottom of the hopper 3. The lower grinding disc 53 rotates relative to the upper grinding disc 4, and the raw materials are ground into powder through friction. The powder is discharged from the edges around the upper grinding disc 4 and the lower grinding disc 53, and finally discharged from the discharge port 21. During the grinding process, due to continuous friction, the temperature of the upper grinding disc 4 and the lower grinding disc 53 continues to rise. In order to avoid the problem of burning the fertilizer raw materials due to excessive temperature, after grinding for a period of time, the linear drive component 558 drives the movable sleeve 552 to move upward through the lever 557, and the movable sleeve 552 drives the turntable 1 556, thereby pushing the slider 553 to move away from the middle of the cylinder 551 through the connecting rod 555. At this time, the ball 554 pushes the cone 5511 to move the cylinder 551 downward, the elastic component 1 550 is compressed, and the cylinder 551 drives the lower grinding disc 53 to move downward, so that the space between the lower grinding disc 53 and the upper grinding disc 4 becomes larger. Then, the fan 6 blows air from the position of the air inlet 22 to the inside of the grinding cylinder 2, specifically, to the space between the upper grinding disc 4 and the lower grinding disc 53, so as to cool the upper grinding disc 4 and the lower grinding disc 53. After cooling, the movable sleeve 552 is driven downward by the linear drive component 558 to drive the slider 553 and the ball 554 to move toward the middle of the cylinder 551. At this time, under the action of the elastic component 550, the cylinder 551 and the lower grinding disc 53 move upward, and the lower grinding disc 53 is close to the upper grinding disc 4, so that grinding processing can be carried out again.

[0036] In the above technical solution, the space between the upper grinding disc 4 and the lower grinding disc 53 is enlarged by moving the lower grinding disc 53 downward, and then blowing air to cool the upper grinding disc 4 and the lower grinding disc 53. On the one hand, the upper grinding disc 4 and the lower grinding disc 53 can be cooled to avoid the burning of the fertilizer raw materials due to excessive temperature in the subsequent processing process. On the other hand, the problem of poor cooling effect caused by a small amount of air blown into the space due to the small space can be avoided.

[0037] Furthermore, if Figure 3 and Figure 6 As shown, a blocking rod 56 is provided inside the movable rod 52 , and a connecting block 57 is fixedly connected to the bottom of the blocking rod 56 . A vertical groove 521 is opened on the side wall of the movable rod 52 . The connecting block 57 is located inside the vertical groove 521 and is fixedly connected to the movable sleeve 552 .

[0038] It should be noted that when the linear drive component 558 drives the movable sleeve 552 to move upward, the movable sleeve 552 can also drive the blocking rod 56 to move upward through the connecting block 57, so that the blocking rod 56 is inserted upward into the bottom of the hopper 3 to block the hopper 3, thereby preventing the unground raw materials in the hopper 3 from falling between the upper grinding disk 4 and the lower grinding disk 53 and being blown away during the air cooling process.

[0039] Furthermore, the bottom of the movable sleeve 552 is rotatably connected to the second turntable 581 , and the bottom of the movable rod 52 is provided with a second elastic component 58 , and two ends of the second elastic component 58 are respectively pressed with the second turntable 581 and the grinding cylinder 2 .

[0040] It should be noted that the second elastic component 58 is a compression spring. By providing the second elastic component 58 , the stability of the movable sleeve 552 can be improved.

[0041] Refer to the instruction manual Figure 3 The inside of the grinding cylinder 2 is fixedly connected with an inclined partition 10, and the partition 10 is movably sleeved on the outside of the cylinder 551. A sealing plate 7 is vertically movably inserted at the lower side of the partition 10. The sealing plate 7 is used to open and close the discharge port 21. A fixing rod 71 is fixedly connected to the bottom of the sealing plate 7, and the lever 557 is fixedly connected to the fixing rod 71.

[0042] It should be noted that, through the setting of the partition 10, the powder discharged from the upper grinding disc 4 and the lower grinding disc 53 slides down from the partition 10 and is finally discharged from the discharge port 21. When the linear drive component 558 drives the movable sleeve 552 upward through the lever 557, the movable sleeve 552 can also drive the blocking plate 7 to move upward through the fixed rod 71, so that the blocking plate 7 closes the discharge port 21, so that during the air cooling process, the wind will not blow the ground powder out of the discharge port 21.

[0043] Refer to the instruction manual Figure 1-Figure 3 and Figure 7 , Figure 8 An air outlet 23 is provided on one side of the upper end of the grinding cylinder 2 , and a breathable bag 8 is detachably connected to the end of the air outlet 23 . The wind blown into the grinding cylinder 2 by the fan 6 enters the breathable bag 8 from the air outlet 23 .

[0044] Furthermore, an annular shoulder 231 is provided at the end of the air outlet 23 , and a nut 9 is threadedly connected to the air outlet 23 . The nut 9 is used to press the opening of the air-permeable bag 8 onto the annular shoulder 231 .

[0045] It should be noted that when in use, the bag opening of the breathable bag 8 is put on the air outlet 23, and then the nut 9 is rotated to press the bag opening onto the annular shoulder 231 through the nut 9, so as to achieve the installation and fixation of the breathable bag 8. During use, wind blows from the air inlet 22 to the inside of the grinding cylinder 2, and then enters the inside of the breathable bag 8 from the air outlet 23. During the air cooling process, some powder will inevitably be blown away. Through the setting of the breathable bag 8, the breathable bag 8 can keep the powder inside, and the wind overflows from the breathable bag 8 to the outside.

[0046] It should be noted that, in order to facilitate the installation of the breathable bag 8, a drawstring can be provided at the bag opening of the breathable bag 8. When the bag opening of the breathable bag 8 is put on the air outlet 23, the bag opening can be tightened by pulling the drawstring, and then the nut 9 can be tightened.

[0047] Furthermore, a spacer 100 and a spacer 2 110 are fixedly connected to the inside of the air inlet 22 and the air outlet 23 respectively, and a cross-shaped opening is formed on the spacer 100 and the spacer 2 110 .

[0048] It should be noted that in order to prevent the powder from entering the fan 6 from the air inlet 22 or entering the air permeable bag 8 from the air outlet 23 during normal grinding, a spacer 100 and a spacer 2 110 are provided. The spacer 100 and the spacer 2 110 can be made of rubber material. During the grinding process, the cross-shaped opening is closed, and during the wind blowing process, the cross-shaped opening is blown open. Therefore, during the grinding process, the powder will not pass through the spacer 100 and the spacer 2 110, and during the air cooling process, the wind can pass through the cross-shaped opening.

[0049] In the above technical scheme, through the setting of the dynamic grinding mechanism 5, the upward movement of the movable sleeve 552 can, on the one hand, drive the lower grinding disc 53 to move downward to increase the space between the upper grinding disc 4 and the lower grinding disc 53 for cooling; on the other hand, it can drive the blocking rod 56 to move upward to block the hopper 3 to prevent raw materials from entering during the cooling process; on the other hand, it can drive the blocking plate 7 to move upward to block the discharge port 21 to prevent the wind from driving the powder out of the discharge port 21 and polluting the environment during the cooling process. The above setting makes the device structure more compact, energy-saving and environmentally friendly.

[0050] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
