Description

Technical Field

[0002] Solid organic fertilizer refers to fertilizer made from animal and plant residues, excrement and other biological materials as the main raw materials, and is made through composting, fermentation and other processing processes. This type of fertilizer is rich in organic matter and a variety of nutrients, which can improve soil structure, increase soil fertility, and provide plants with necessary nutrients.

[0003] In the process of selecting solid organic fertilizer raw materials, fish bones are widely selected because they are rich in elements such as calcium, phosphorus and magnesium (which help to enhance the lodging resistance of crops and fruit quality, and can also increase organic matter in the soil). When fish bones (bone residue after pretreatment) are selected as solid organic fertilizer raw materials, in order to solve the problem that only the surface area of ​​fish bones can be quickly decomposed by microorganisms and enzymes, resulting in a long fermentation cycle, it is usually necessary to grind the fish bones to increase the contact area between the fish bones and the microorganisms and enzymes. When the fish bones are ground by grinding discs, due to the irregular shape and different sizes of the fish bones, the fish bones will be stuck between the grinding discs when moving between the grinding discs and cannot be ground into powder in time, resulting in low grinding efficiency.

DETAILED DESCRIPTION

[0052] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] In the above scheme, the base 1 is a rectangular shell, the interior of which can be used to place the motor 5 to ensure that a stable supporting force is provided for the grinding disc 7. The base 1 is provided with a CNC table. The number of hydraulic push rods 3 is two. The telescopic ends of the two hydraulic push rods 3 are fixedly connected to the first grinding ring 4. The two hydraulic push rods 3 are electrically connected to the CNC table on the base 1. The lower side of the first grinding ring 4 is provided with grinding grooves. The motor 5 is located in the base 1, and the motor 5 is electrically connected to the CNC table on the base 1. In this embodiment, the transmission frame 6 and the grinding disc 7 can be regarded as fixedly connected. The upper side of the grinding disc 7 and the lower side of the second grinding ring 8 are both provided with grinding grooves. The distance between the upper side of the grinding disc 7 and the lower side of the second grinding ring 8 can be adjusted according to the required grinding fineness of the fish bones. The lower side of the second grinding ring 8 is provided with an annular inclined surface for providing space for the movement of the fish bones and continuously refining the fish bones. The collecting shell 9 is an existing mechanism for collecting the ground fish bones.

[0055] like Figure 2-Figure 9As shown, the material unloading assembly includes: a material storage shell 1101, which is slidably connected to the telescopic part of the hydraulic push rod 3, and the material storage shell 1101 is externally connected with a vibration unloading mechanism for enhancing the mobility of the fishbone on the surface of the material storage shell 1101, and the first grinding ring 4 is in contact with the material storage shell 1101; a fixed plate 1102, which is fixedly connected to the telescopic part of the hydraulic push rod 3, and the fixed plate 1102 is fixedly connected with a sealing shell 1103, and the sealing shell 1103 is limitedly slidably connected with an extrusion piece 1104; a shielding frame 1105, which is slidably connected to the extrusion piece 1104, and the maximum diameter of the shielding frame 1105 is equal to the inner diameter of the first grinding ring 4, and the maximum diameter of the extrusion piece 1104 is equal to the maximum diameter of the shielding frame 1105, and the transmission frame 6 is rotatably connected with a rotating disk 1106, and the rotating disk 1106 is used to extrude the extrusion piece 1104 and the shielding frame 1105.

[0056] In the above scheme, the thickness of the material storage shell 1101 gradually increases from the center to the periphery, so as to make the fish bones gather in the middle of the material storage shell 1101. The vibrating feeding mechanism connected to the material storage shell 1101 is an existing device, such as a vibrator, which is used to drive the material storage shell 1101 to move slightly up and down. Its specific structure is not shown in the figure. The sealing shell 1103 is a cylinder, and the extrusion member 1104 is composed of a round rod and an extrusion disk. The diameter of the extrusion disk of the extrusion member 1104 and the maximum diameter of the shielding frame 1105 are both equal to the inner diameter of the first grinding ring 4, so as to avoid shielding. A gap appears between the outer side surface of the blocking frame 1105 and the inner side surface of the first grinding ring 4, causing the fishbone to fall in. The inner side surface of the blocking frame 1105 is provided with a slope, which is used to make the fishbone fall to the middle part of the extrusion disk in the extrusion member 1104. After the extrusion member 1104 contacts with the rotating disk 1106, there is friction between the extrusion member 1104 and the rotating disk 1106, and there is friction between the rotating disk 1106 and the transmission frame 6. The friction generated after the extrusion member 1104 contacts with the rotating disk 1106 is greater than the friction between the rotating disk 1106 and the transmission frame 6.

[0057] like Figure 4-Figure 7 and Fig. 9 As shown, it also includes: a first airbag 1201, which is fixed to the extrusion piece 1104. When the first airbag 1201 is filled with air, it is used to support the shielding frame 1105. The first airbag 1201 is used to remove the fish bone from the extrusion piece 1104 when the extrusion piece 1104 moves to the unloading position.

[0058] In the above scheme, the first airbag 1201 is made of puncture-proof material, such as fabric-reinforced rubber, to prevent the first airbag 1201 from being damaged by fish bones after inflation. The first airbag 1201 is externally connected to an inflation device, which is an existing device and its specific structure is not shown in the figure.

[0059] Before using the device to grind fish bones, the staff first puts the fish bones to be ground on the storage shell 1101, and then the staff starts the vibration unloading mechanism connected to the storage shell 1101 through the CNC table on the base 1 to ensure that part of the fish bones slides into the center hole of the first grinding ring 4 and the middle of the shielding frame 1105. Finally, the staff starts the two hydraulic push rods 3 and the motor 5 through the CNC table on the base 1, and the output shaft of the motor 5 starts to drive the transmission frame 6 to rotate, and the transmission frame 6 drives the grinding disc 7 and the rotating disc 1106 to rotate, and the telescopic parts of the two hydraulic push rods 3 start to move up and down intermittently, jointly driving the storage shell 1101 and the first grinding ring 4 to move back and forth up and down.

[0060] When the telescopic parts of the two hydraulic push rods 3 move downward, the telescopic parts of the two hydraulic push rods 3 drive the sealing shell 1103 to move downward through the fixing plate 1102, the sealing shell 1103 drives the extrusion piece 1104 to move downward, and the extrusion piece 1104 drives the shielding frame 1105 to move downward continuously.

[0061] When the lower side of the shielding frame 1105 contacts the upper side of the rotating disk 1106, the rotating disk 1106 stops rotating and the extrusion piece 1104 continues to move downward. The lower side of the shielding frame 1105 moves upward along the inner side of the first grinding ring 4 relative to the extrusion piece 1104 under the limitation of the upper side of the rotating disk 1106, and the fishbone falls onto the extrusion disk inside the extrusion piece 1104 under the guidance of the slope of the inner wall of the shielding frame 1105.

[0062] When the lower side of the extrusion piece 1104 contacts the upper side of the rotating disk 1106, the shielding frame 1105 stops moving upward relative to the extrusion piece 1104, and the exposed amount of the fishbone on the extrusion disk inside the extrusion piece 1104 reaches the maximum. At this time, the staff starts the external inflation device of the first airbag 1201 through the CNC table on the base 1, and instantly inflates the first airbag 1201. The first airbag 1201 begins to expand and squeezes the fishbone on the extrusion disk inside the extrusion piece 1104 to the surroundings, causing the fishbone to fall onto the grinding disk 7. The fishbone is blocked by the center hole in the second grinding ring 8, which limits the range of movement of the fishbone due to squeezing.

[0063] When the first airbag 1201 is inflated, the staff turns off the external inflation device of the first airbag 1201 through the CNC table on the base 1. The first airbag 1201 blocks the fishbones above itself to prevent the fishbones from continuously falling along the inner side of the shielding frame 1105 to the extrusion disk in the extrusion piece 1104. At the same time, the staff starts the external vibration unloading mechanism of the storage shell 1101 through the CNC table on the base 1. The vibration unloading mechanism drives the storage shell 1101 to move up and down, so that the fishbones slide along the surface of the storage shell 1101 into the shielding frame 1105, thereby replenishing the fishbones in the shielding frame 1105.

[0064] In the above-mentioned process of squeezing out the fishbone on the extrusion plate in the extrusion piece 1104, the telescopic parts of the two hydraulic push rods 3 continue to drive the first grinding ring 4 and the storage shell 1101 to move downward, and the extrusion plate of the extrusion piece 1104 moves upward relative to the first grinding ring 4 under the extrusion of the rotating disk 1106, and the extrusion piece 1104 moves upward along the sealing shell 1103. The extrusion piece 1104 drives the shielding frame 1105 to move upward along the inner side surface of the first grinding ring 4 through the first airbag 1201.

[0065] When the first grinding ring 4 moves downward, the first grinding ring 4 gradually approaches the fish bone that falls onto the grinding disc 7, and then the first grinding ring 4 contacts and squeezes the fish bone that falls onto the grinding disc 7. Under the continuous rotation of the grinding disc 7, the fish bone on the grinding disc 7 is gradually ground and refined, and moves around under the action of the grinding patterns on the first grinding ring 4, the grinding disc 7 and the second grinding ring 8, and is further ground and refined. At the same time, the material storage shell 1101 continues to move downward until the lower side of the material storage shell 1101 contacts the upper side of the second grinding ring 8, and the staff closes the two hydraulic push rods 3 through the CNC table on the base 1.

[0066] The fish bones are pre-crushed by means of the first grinding ring 4 by means of compression and grinding, thereby ensuring that the fish bones can move between the grinding disc 7 and the second grinding ring 8, and the fish bone powder is further refined by means of continuous grinding by the grinding disc 7 and the second grinding ring 8.

[0067] After the fish bone dropped onto the grinding disc 7 has been ground for a preset time, the staff starts the two hydraulic push rods 3 through the numerical control table on the base 1, and the telescopic parts of the two hydraulic push rods 3 move upward to jointly drive the first grinding ring 4 and the material storage shell 1101 to move upward.

[0068] When the first grinding ring 4 and the material storage shell 1101 move upward, first the extrusion piece 1104 moves downward relative to the first grinding ring 4 under the action of its own gravity, and restores the initial position of the first grinding ring 4 relative to the sealing shell 1103, and then the sealing shell 1103 drives the extrusion piece 1104 to move upward. When the extrusion piece 1104 returns to the initial position, the staff starts the external inflation device of the first airbag 1201 through the CNC table on the base 1, and the gas in the first airbag 1201 is extracted. The first airbag 1201 shrinks and returns to its initial size, and the staff closes the external inflation device of the first airbag 1201 through the CNC table on the base 1.

[0069] When the first airbag 1201 is reset, the shielding frame 1105 moves downward relative to the extrusion member 1104 under the action of its own gravity until the shielding frame 1105 is restored to its original position relative to the extrusion member 1104 .

[0070] After completing the grinding of some fish bones, the above-mentioned two hydraulic push rods 3 move up and down continuously to grind a batch of fish bones.

[0071] When the device is stopped from being used to grind fish bones, the staff starts the two hydraulic push rods 3 and turns off the motor 5 through the CNC table on the base 1. The telescopic parts of the two hydraulic push rods 3 jointly drive the storage shell 1101, the first grinding ring 4, the fixed plate 1102 and the attached parts on the fixed plate 1102 to reset. Then the staff turns off the two hydraulic push rods 3 through the CNC table on the base 1, and finally collects the fish bone powder in the shell 9 and cleans the device.

[0072] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes: an inflation component, which is arranged in the sealing shell 1103, and the inflation component is used to inflate the first airbag 1201 when the extrusion piece 1104 moves to the unloading position. The inflation component includes: a sliding ring 1301, which is fixed to the extrusion piece 1104, and the sliding ring 1301 is sealed and slidably connected with the sealing shell 1103. The extrusion piece 1104 completely fills the central hole of the sliding ring 1301, and a first elastic member 1302 is fixed between the sliding ring 1301 and the sealing shell 1103. The extrusion piece 1104 is provided with a circular blind hole and a plurality of through holes. The plurality of through holes of the extrusion piece 1104 are connected with the circular blind hole and the first airbag 1201, and the circular blind hole of the extrusion piece 1104 is connected with the sealing shell 1103; a time-delay reset component, which is arranged in the circular blind hole of the extrusion piece 1104, and the time-delay reset component is used to slow down the contraction speed of the first airbag 1201.

[0073] In the above scheme, the first elastic member 1302 is a spring and is initially in a charged state, which is used to ensure that the sliding ring 1301 fits tightly with the sealing shell 1103, and the circular blind hole of the extrusion member 1104, several through holes of the extrusion member 1104, the sealing shell 1103 and the first airbag 1201 are all filled with gas.

[0074] like Figure 7 and Figure 8 As shown, the delayed reset component includes: a sealing disk 1401, which is fixedly connected to the circular blind hole of the extrusion piece 1104, the diameter of the sealing disk 1401 is equal to the diameter of the circular blind hole of the extrusion piece 1104, and the sealing disk 1401 is provided with two through holes; a first one-way valve 1402, which is fixedly connected to one of the through holes of the sealing disk 1401, and a first pressure relief valve 1403 is fixedly connected to the other through hole of the sealing disk 1401; a second air bag 1404, which is fixedly connected to the sealing shell 1103, and the second air bag 1404 is provided with two ventilation holes, the two ventilation holes of the second air bag 1404 are both connected to the sealing shell 1103, and the two ventilation holes of the second air bag 1404 are respectively fixedly connected with a second one-way valve 1405 and a second pressure relief valve 1406.

[0075] In the above scheme, the first one-way valve 1402 is used to allow the gas in the sealed shell 1103 to flow into the circular blind hole of the extrusion piece 1104, the first pressure relief valve 1403 is used to allow the gas in the circular blind hole of the extrusion piece 1104 to flow into the sealed shell 1103, the second one-way valve 1405 is used to allow the gas in the second airbag 1404 to flow into the sealed shell 1103, the second pressure relief valve 1406 is used to allow the gas in the sealed shell 1103 to flow into the second airbag 1404, and the second airbag 1404 is filled with gas.

[0076] When the sealing shell 1103 moves downward, the action of the rotating disk 1106 squeezing the extrusion member 1104 in Example 1 is repeated, and the extrusion member 1104 moves upward relative to the first grinding ring 4. The extrusion member 1104 drives the sliding ring 1301 to move upward, so that the first elastic member 1302 is compressed, and at the same time, the gas in the sealing shell 1103 flows into the circular blind hole of the extrusion member 1104 through the first one-way valve 1402, and then the gas flows into the first airbag 1201 through several through holes of the extrusion member 1104, and the first airbag 1201 swells to replace the inflation device in Example 1. The action of the first airbag 1201 inflating and swelling in Example 1 is repeated. As the first grinding ring 4 continues to move downward, the remaining gas in the sealing shell 1103 enters the second airbag 1404 through the second pressure relief valve 1406, and the second airbag 1404 inflates and swells. When the sealing shell 1103 is When 1103 moves upward, the action of the first grinding ring 4 and the material storage shell 1101 moving upward in Example 1 is repeated, and the sliding ring 1301 moves downward relative to the first grinding ring 4 under the elastic action of the two first elastic members 1302, and the sliding ring 1301 drives the extrusion member 1104 to move downward, firstly the gas in the second airbag 1404 is drawn back into the sealing shell 1103 through the second one-way valve 1405, and then the gas in the first airbag 1201 flows back into the sealing shell 1103 through several through holes of the extrusion member 1104, the circular blind hole of the extrusion member 1104 and the first pressure relief valve 1403, delaying the resetting time of the first airbag 1201, ensuring that after the first airbag 1201 is quickly reset, the shielding frame 1105 cannot be reset due to the limitation of the rotating disk 1106, resulting in a large amount of fishbone leakage from the middle of the shielding frame 1105.

[0077] When the first airbag 1201 is contracted and reset, the sliding ring 1301 continues to move downward and extracts gas from the air, and finally completes the reset.

The protection component includes: a plurality of sliding blocks 1601, which are all fixedly connected to the grinding disc 7. The transmission frame 6 is provided with rectangular sliding grooves with the same number as the sliding blocks 1601. The sliding blocks 1601 slide in the adjacent rectangular sliding grooves on the transmission frame 6, and the transmission frame 6 is slidably connected to the grinding disc 7; a second elastic member 1602 is fixedly connected between the transmission frame 6 and the grinding disc 7.

[0079] In the above scheme, the number of sliding blocks 1601 is four, and the four sliding blocks 1601 are evenly distributed circumferentially to increase the stability of the rotation of the grinding disc 7. The second elastic member 1602 is a spring, and the number of the second elastic members 1602 is four, and the four second elastic members 1602 are evenly distributed circumferentially.

[0080] In order to solve the problem that the fish bones are of different sizes, if there are many large fish bones falling onto the grinding disc 7, the first grinding ring 4 will squeeze the fish bones and indirectly over-squeeze the grinding disc 7, which will increase the wear of the grinding disc 7. Details are as follows:

[0081] When grinding fish bones, repeat the process of starting the motor 5 through the CNC table on the base 1 in Example 1, the output shaft of the motor 5 drives the transmission frame 6 to rotate, the transmission frame 6 drives the four sliding blocks 1601 to rotate through the four rectangular slide grooves thereon, and the four sliding blocks 1601 jointly drive the grinding disc 7 to rotate.

[0082] Repeat the action of the first grinding ring 4 squeezing the fish bones that fall onto the grinding disc 7 in Example 1. If there are more large bones among the fish bones that fall onto the grinding disc 7, the grinding disc 7 is over-squeezed, and the four second elastic members 1602 are compressed. The grinding disc 7 slides downward along the adjacent rectangular slide grooves on the transmission frame 6 through the four sliding blocks 1601, thereby reducing the squeezing force on the grinding disc 7. As the grinding disc 7 continues to rotate, the fish bones of the first grinding ring 4 and the grinding disc 7 are gradually refined, and the grinding disc 7 moves upward and resets under the drive of the four second elastic members 1602, and the grinding disc 7 drives the four sliding blocks 1601 to move upward and reset.

[0083] Embodiment 4: Based on embodiment 1, Figure 3-Figure 7 and Fig.10 As shown, it also includes: a pushing assembly, which is arranged on the frame 2, and is used to squeeze the fish bones in the first grinding ring 4 and the shielding frame 1105. The pushing assembly includes: a fixed rod 1701, which is fixed to the frame 2, and the fixed rod 1701 is slidably connected to a pushing plate 1702, and the pushing plate 1702 is provided with a plurality of circular pin holes, and a third elastic member 1703 is fixed between the fixed rod 1701 and the pushing plate 1702; a clearing assembly, which is arranged on the fixed rod 1701, and is used to clear the fish bones stuck in the center hole of the first grinding ring 4 and the shielding frame 1105.

[0084] In the above scheme, there are two fixed rods 1701, which are symmetrically distributed. Both fixed rods 1701 are slidingly connected to the push plate 1702. The third elastic member 1703 is a spring and is initially in a force storage state, which is used to make the push plate 1702 generate a driving force.

[0085] like Figure 4-Figure 7 and Fig.10 As shown, the clearing assembly includes: a fixed ring 1801, fixedly connected to the fixed rod 1701, and an extrusion piece 1104 is slidably connected to the fixed ring 1801; there are several push pins 1802, all fixedly connected to the fixed ring 1801, and the several push pins 1802 correspond one by one to the circular pin holes of the several push plates 1702, and the diameter of the push pins 1802 is equal to the diameter of the circular pin holes of the push plates 1702.

[0086] In the above scheme, the fixing ring 1801 is made of a hard material, such as carbon steel, and is used to provide a stable support force for the push pin 1802. The push pin 1802 can be made of a smooth material, such as stainless steel, and is used to reduce the amount of fish bones adhering to the push pin 1802. The diameter of the push pin 1802 is equal to the diameter of the circular pin hole of the push plate 1702, and is used to clean the push pin 1802 when the push pin 1802 is reset.

[0087] In order to solve the problem that the fish bones are of different sizes and contain fish bones, which may cause the fish bones to get stuck in the center hole of the first grinding ring 4, resulting in blockage of the center hole of the first grinding ring 4 and affecting the fish bone grinding efficiency, the present invention repeats the action of the telescopic parts of the two hydraulic push rods 3 in Example 1 to jointly drive the first grinding ring 4 and the storage shell 1101 to move upward, but the upward movement distance of the first grinding ring 4 in this embodiment is greater than the upward movement distance of the first grinding ring 4 in Example 1, to ensure that the fish bones in the center hole of the first grinding ring 4 are fully squeezed, and during the upward movement of the first grinding ring 4, the push plate 1702 enters the center hole of the first grinding ring 4 to squeeze and compact the fish bones in the center hole of the first grinding ring 4, thereby ensuring the amount of fish bones that fall into the cylinder composed of the shielding frame 1105 and the extrusion disk in the extrusion member 1104. When the fishbones in the center hole of the first grinding ring 4 are arranged in a disorderly manner and are difficult to be pushed by the pushing plate 1702, the first grinding ring 4 moves upward, causing the fishbones to squeeze the pushing plate 1702 and slide upward along the two fixed rods 1701. At the same time, the two third elastic members 1703 are compressed. As the pushing plate 1702 continues to move upward, a number of pushing pins 1802 respectively pass through the adjacent pin holes on the pushing plate 1702, and then a number of pushing pins 1802 are inserted into the fishbones to squeeze the fishbones, thereby disrupting the arrangement of the fishbones in the center hole of the first grinding ring 4 and clearing the blockage of the fishbones in the center hole of the first grinding ring 4.

[0088] Repeat the downward movement of the first grinding ring 4 in Example 1. The first grinding ring 4 drives the fish bones to move downward, gradually releasing the squeezing of the push plate 1702. The push plate 1702 is reset under the elastic force of the two third elastic members 1703, and the fish bones adhered to the surface of the push pin 1802 are scraped off.

[0089] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
