DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] Embodiment 1:

[0044] Reference Figure 1-Figure 8, an organic fertilizer processing equipment, including a tank body 1, the end of the tank body 1 is arranged on a bracket, and the bottom of the bracket can be installed with universal wheels to realize the movement of the tank body 1. This is a conventional means in the prior art, so it is not described in detail, and also includes: a crushing unit arranged in the tank body 1, used to crush the organic fertilizer, and a return material screening unit is arranged in the crushing unit, used to screen the crushed organic fertilizer, and transport the larger organic fertilizer to the crushing unit for secondary crushing; a feeding unit arranged on the tank body 1, used to add the organic fertilizer to the crushing unit, and the return material screening unit is connected to the feeding unit through a pipeline; a mixing unit arranged in the tank body 1, the return material screening unit is connected to the mixing unit through a pipeline, and is used to drive a part of the structure of the mixing unit to reciprocate up and down in the tank body 1, wherein a linkage unit is arranged between the crushing unit and the mixing unit, used to drive the crushing unit and the mixing unit to rotate synchronously.

[0045] Reference Figure 2 , Figure 3 , Figure 5 and Figure 7 The crushing unit includes a plurality of crushing chambers 3 opened inside the tank body 1, and a crushing disk 4 is rotatably connected inside the crushing chamber 3. The return material screening unit includes a spiral plate 9 and a fixed ring 11, and the spiral plate 9 and the fixed ring 11 are both fixedly connected to the inner wall of the crushing chamber 3, and a vibration ring 12 is slidably connected inside the fixed ring 11, and a screen plate 13 is fixedly connected to the top of the vibration ring 12. A plurality of compression cylinders 14 are fixedly connected to the bottom side of the fixed ring 11, and a slider 15 that fits the fixed ring 11 is fixedly connected to the top of the compression cylinder 14, and a first spring 141 is fixedly connected between the slider 15 and the bottom of the fixed ring 11, and a vibration cylinder 16 and a second spring 17 are fixedly connected between the slider 15 and the vibration ring 12, wherein the spiral plate 9 fits the side wall of the crushing disk 4, the screen plate 13 is located below the crushing disk 4 and fits the side wall of the crushing chamber 3, and an ejection mechanism is arranged between the slider 15 and the fixed ring 11.

[0046] The number of crushing chambers 3 is not limited here, and the staff can set it according to the processing conditions of the organic fertilizer. In addition, the spiral direction of the spiral plate 9 is opposite to the rotation direction of the crushing disk 4. When the organic fertilizer is crushed, the completely crushed organic fertilizer will fall onto the screen plate 13, and the completely crushed organic fertilizer will be thrown onto the spiral plate 9 under the action of centrifugal force, and as the crushing disk 4 rotates, the organic fertilizer is driven to be transported upward along the spiral plate 9, and finally falls onto the crushing disk 4 through the top of the spiral plate 9 for secondary crushing to ensure that the organic fertilizer is completely crushed. In addition, the screen plate 13 is driven to vibrate under the action of the vibrating cylinder 16 and the second spring 17, thereby accelerating the screening efficiency of the organic fertilizer and avoiding blockage of the screen plate 13.

[0047] Reference Figure 2 , Figure 7 and Figure 8 The ejection mechanism includes a plurality of mounting grooves 151 provided on one side of the side wall of the slider 15 close to the fixing ring 11, a plurality of ratchet teeth 152 are fixedly connected to one side of the inner wall of the fixing ring 11 close to the mounting groove 151, a pawl 153 is rotatably connected inside the mounting groove 151, a third spring 154 is fixedly connected between the pawl 153 and the top of the mounting groove 151, a pushing cylinder 155 is fixedly connected to the bottom of the mounting groove 151, wherein the pawl 153 matches the ratchet teeth 152, the pushing cylinder 155 is located below the pawl 153, and the pushing cylinder 155 is connected to the compression cylinder 14 through a pipeline.

[0048] The specific structure of the ratchet 152 and the pawl 153 can refer to the technical solutions in the prior art, and those skilled in the art can know that it will not be described here. As the amount of organic fertilizer with larger size on the sieve plate 13 increases, the sieve plate 13 will gradually move downward during the vibration process, and at the same time, the first spring 141 is compressed by the slider 15 to store elastic potential energy. When the organic fertilizer retained on the sieve plate 13 reaches a threshold, the gas compressed by the compression cylinder 14 drives the push cylinder 155 to extend outward, pushing the pawl 153 and the sieve plate 13 to move downward. The ratchet 152 disengages, causing the sieve plate 13 to eject upward, pushing the organic fertilizer retained on the sieve plate 13 onto the crushing disk 4 for secondary crushing, and according to the compression frequency of the compression cylinder 14 (the compression frequency is faster because the organic fertilizer is added faster), part of the compression cylinder 14 is transported to the first annular cylinder 20. Due to the high frequency, the exhaust speed of the exhaust valve 22 is constant, thereby driving the baffle 19 to rotate upward, reducing the feeding speed of the organic fertilizer, and ensuring the efficiency and effect of the organic fertilizer crushing.

[0049] Reference Figure 1 , Figure 2 and Figure 6 The feeding unit includes a feeding hopper 2 fixedly connected to the top of the tank body 1, a limiting block 18 is fixedly connected to the inner wall of the feeding hopper 2, a baffle 19 is rotatably connected to the side of the inside of the feeding hopper 2 away from the limiting block 18, a first annular cylinder 20 and a second annular cylinder 21 are fixedly connected between the bottom of the baffle 19 and the inner wall of the feeding hopper 2, wherein the end of the baffle 19 matches the limiting block 18, the axis of the first annular cylinder 20 and the second annular cylinder 21 are located on the same straight line with the axis of the baffle 19, a relief valve 22 is provided on the first annular cylinder 20, and the first annular cylinder 20 is connected to the compression cylinder 14 through a pipeline.

[0050] Initially, the organic fertilizer drives the baffle 19 to rotate downward under the action of its own gravity. If the organic fertilizer is added too quickly, the amount of organic fertilizer that is not completely crushed and retained on the sieve plate 13 increases, and the weight on the sieve plate 13 increases faster. Part of the gas in the compression cylinder 14 enters the first annular cylinder 20, and the speed of air intake is greater than the speed of the air relief valve 22, thereby driving the baffle 19 to rotate upward, reducing the speed of adding the organic fertilizer, so that the speed of adding the organic fertilizer and the speed of crushing the organic fertilizer reach the optimal state.

[0051] Reference Figure 2 The mixing unit includes a rotating shaft 10 rotatably connected to the inside of the tank body 1, two groups of stirring rods 25 are fixedly connected to one side of the rotating shaft 10 near the mixing chamber 24, and multiple groups of two-way cylinders 26 are fixedly connected between the two groups of stirring rods 25. The bottom end of the rotating shaft 10 is fixedly connected to a spiral rod 33, wherein the middle position of the two-way cylinder 26 is connected to the rotating shaft 10, and the two-way cylinder 26 is connected to the vibration cylinder 16 through a pipeline. Multiple groups of monitoring mechanisms are arranged on the inner wall of the mixing chamber 24, and also includes a mixing chamber 24 opened in the tank body 1, the mixing chamber 24 is located below the crushing chamber 3, and a connecting channel 23 is connected between the mixing chamber 24 and the crushing chamber 3. The bottom of the mixing chamber 24 is conically arranged, and also includes a discharge port 32 opened at the bottom end of the tank body 1, and the end of the spiral rod 33 extends to the inside of the discharge port 32, and the outer wall of the spiral rod 33 is in contact with the inner wall of the discharge port 32.

[0052] The specific structure of the two-way cylinder 26 can refer to the technical solutions in the prior art. Those skilled in the art will know that it will not be elaborated here. When the sieve plate 13 vibrates, the compressed gas will enter the two-way cylinder 26, thereby driving the two-way cylinder 26 to extend and contract, so that the stirring rod 25 can continuously adjust its position when stirring the organic fertilizer, so that the organic fertilizer is mixed more evenly. In addition, it drives the spiral rod 33 to rotate and transport the organic fertilizer at the bottom of the mixing chamber 24 upward to avoid uneven mixing of organic fertilizers with different specific gravities. In addition, the discharge port 32 can also be sealed until the organic fertilizer is completely mixed.

[0053] Reference Figure 2 The monitoring mechanism includes a plurality of grooves 27 formed on the inner wall of the mixing chamber 24, wherein a compression plate 28 is rotatably connected to the interior of the groove 27, a driving cylinder 29 and a monitoring cylinder 31 are fixedly connected to the side of the groove 27 close to the compression plate 28, a fourth spring 30 sleeved on the outside of the driving cylinder 29 is fixedly connected between the compression plate 28 and the groove 27, wherein the groove 27 is located between the two groups of stirring rods 25, the side wall of the compression plate 28 is inclined, the driving cylinder 29 is fitted with the compression plate 28, the driving cylinder 29 is connected to the vibration cylinder 16 through a pipeline, and the monitoring cylinder 31 is connected to the second annular cylinder 21 through a pipeline.

[0054] When the organic fertilizer is mixed, the pressure on the compression plate 28 is different according to the amount of organic fertilizer in the mixing chamber 24, and the pressure on the compression plate 28 is different due to the different positions of the stirring rod 25 during the rotation process (that is, the compression plate 28 will vibrate), and during the vibration process, the compressed gas is transported to the vibration cylinder 16 to enhance the vibration effect of the sieve plate 13. When the amount of organic fertilizer in the mixing chamber 24 reaches a certain amount, the compression plate 28 will rotate into the groove 27 during the vibration process until it contacts and compresses the monitoring cylinder 31, and transports the compressed gas to the second annular cylinder 21, driving the baffle 19 to rotate upward until the baffle 19 is closed.

[0055] Reference Figure 1-Figure 2 The linkage unit includes a motor 5 fixedly connected to the top of the tank body 1, the shaft of the crushing disc 4 and the rotating shaft 10 extend to the outside of the tank body 1, and one group of the shafts of the crushing discs 4 are connected to the output end of the motor 5, the shaft of the crushing disc 4 is fixedly connected to a driving wheel 6, the top of the rotating shaft 10 is fixedly connected to a linkage wheel 7, and a belt 8 is sleeved between the driving wheel 6 and the linkage wheel 7.

[0056] Before processing the organic fertilizer, the motor 5 is first started to drive the driving wheel 6 and the crushing disk 4 to rotate. Under the action of the belt 8, the linkage wheel 7 and the rotating shaft 10 are driven to rotate, so that the organic fertilizer is crushed and mixed at the same time, which saves time and labor and reduces energy loss.

[0057] Embodiment 2:

[0058] A processing method of organic fertilizer processing equipment comprises the following steps:

[0059] Step 1: adding different types of organic fertilizers into different crushing units through different feeding units, and crushing the organic fertilizers through the crushing units;

[0060] Different organic fertilizers in specified proportions can be added to different feed hoppers 2 at a time to ensure that the proportion of each component in the organic fertilizer meets the requirements of the fertilizer composition;

[0061] Step 2: During the crushing process of organic fertilizer, the completely crushed organic fertilizer enters the mixing unit through the vibrating return material screening unit, and the larger organic fertilizer stays on the return material screening unit or is thrown onto the return material screening unit under the action of centrifugation. Some organic fertilizer will be transported to the crushing unit again through the return material screening unit for secondary crushing;

[0062] This can avoid the sieve plate 13 from being blocked;

[0063] Step 3: When the amount of organic fertilizer retained on the return material screening unit reaches a certain amount, the organic fertilizer will be pushed to the crushing unit for secondary crushing through the ejection mechanism. At the same time, the feeding speed of the feeding unit is adjusted according to the working frequency of the ejection mechanism to ensure the best crushing efficiency and effect of the organic fertilizer;

[0064] The speed of the organic fertilizer retained on the sieve plate 13 can reflect the adding speed of the organic fertilizer, so that the retained stable organic fertilizer can be directly crushed for the second time to increase the crushing speed of the organic fertilizer;

[0065] Step 4: The linkage unit can drive the crushing unit and the mixing unit to rotate synchronously. The crushed organic fertilizer will be mixed under the action of the mixing unit. At the same time, the position of the mixing unit during mixing is adjusted under the action of the return material screening unit to improve the mixing effect and efficiency of the organic fertilizer.

[0066] Step 5: The amount of organic fertilizer in the mixing unit can be monitored by the monitoring mechanism. When the amount of mixed organic fertilizer reaches a threshold, the feeding unit is closed by the monitoring mechanism to ensure the mixing effect of the organic fertilizer. At the same time, the monitoring mechanism can also improve the vibration effect of the return material screening unit and speed up the screening efficiency of the organic fertilizer.

[0067] The above description 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.
