[0014] A method for using a pulverizing device for organic fertilizer fermentation pretreatment, the method comprising the following steps:

[0015] When crushing organic fertilizer, some small-volume dry materials are directly added into the crushing box from the feed pipe, and wet organic fertilizers are added into the barrel from the hopper. The motor is controlled to drive the driving gear to rotate, and the driving gear drives the second transmission wheel to rotate through the transmission gear. The second transmission wheel drives the first transmission wheel and the connecting shaft to rotate through the transmission belt, and the connecting shaft drives the conical shaft and the spiral extrusion piece to rotate. The spiral extrusion piece can crush the organic fertilizer during the rotation process and transport the organic fertilizer to the left, because the thread pitch on the spiral extrusion piece is from right to left. The pressure is gradually reduced, so that the spiral extrusion piece can push the fertilizer from the position with large spiral pitch to the position with small spiral pitch, so as to achieve the purpose of extruding the fertilizer, so that the spiral extrusion piece can squeeze the shredded fertilizer while conveying the organic fertilizer, and the squeezed water can leak out through the water filter hole outside the barrel and be collected in the collection box. Because the ferrule is installed at the end of the barrel, and there is a gap between the ferrule and the conical shaft, the spiral extrusion piece can push the fertilizer into the gap and detach from the barrel when conveying it, and the squeezed organic fertilizer falls into the crushing box from the ferrule at the end of the barrel;

[0016] At the same time, the connecting shaft drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission belt, and the driven wheel drives the rotating rod and the two telescopic components to rotate clockwise. The knocking block in the telescopic component can contact the inclined surface of the block during the movement, and the knocking block can slide in the sliding sleeve and squeeze the spring during the pressure. When the knocking block is separated from the knocking block, the elastic force of the spring supports the knocking block so that the knocking block can quickly extend and knock the barrel. The knocking block can continuously knock the barrel during the rotation of the knocking block, and the residue in the water filter hole can be shaken out during the vibration of the barrel, so as to prevent the spiral extrusion sheet from causing blockage in the water filter hole during the process of extruding and conveying fertilizer.

[0017] When the organic fertilizer falls into the crushing box, the transmission gear drives the scattering piece to rotate through the rotating shaft, and the scattering piece can scatter the fallen organic fertilizer, which is beneficial to improve the subsequent crushing effect. Because the two driving gears are meshed with each other, the two driving gears respectively drive the two crushing rollers to rotate relatively and crush the organic fertilizer. The crushed organic fertilizer falls into the mixing box through the opening at the bottom of the crushing box. Because one of the driving gears is fixed to the large belt wheel, the large belt wheel drives the small belt wheel to rotate through the belt, and the small belt wheel drives the paddle blade to rotate through the stirring rod. The paddle blade can scatter the crushed organic fertilizer and fully stir it, so that various raw materials in the organic fertilizer can be fully mixed;

[0018] When it is necessary to adjust the humidity of the organic fertilizer inside the mixing box, the solenoid valve is opened to allow the liquid stored in the collecting box to enter the mixing box to adjust the humidity of the organic fertilizer. After completing the stirring of the organic fertilizer, the discharge valve at the bottom of the mixing box is opened to discharge the fertilizer, thereby completing the fermentation pretreatment of the organic fertilizer.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention adds wet organic fertilizer from a hopper into a barrel, and the connecting shaft drives the conical shaft and the spiral extrusion piece to rotate. The spiral extrusion piece can crush the organic fertilizer during the rotation and transport the organic fertilizer to the left. Since the thread pitch on the spiral extrusion piece decreases step by step from right to left, the spiral extrusion piece can squeeze the crushed fertilizer while transporting the organic fertilizer. The squeezed water can leak out through the water filter hole outside the barrel and be collected in the collection box. The connecting shaft drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission belt, and the driven wheel drives the rotating rod and two The telescopic component rotates clockwise, and when the knocking block is separated from the knocking block, the knocking block is supported by the elastic force of the spring, so that the knocking block can be quickly extended and knock on the barrel. The knocking block can continue to knock on the barrel during rotation, and the residue in the water filter hole can be shaken out during the vibration of the barrel, thereby preventing the spiral extrusion sheet from squeezing and transporting the fertilizer and causing blockage of the water filter hole. Therefore, the wet organic fertilizer can be minced, and the water therein can be squeezed out for independent collection, thereby preventing the fertilizer from sticking together and causing sticking to the knife and affecting the crushing effect, thereby improving the subsequent fermentation effect of the organic fertilizer.

[0021] 2. The present invention drives two crushing rollers to rotate relative to each other and crushes the organic fertilizer through two driving gears. The crushed organic fertilizer falls into the mixing box through the opening at the bottom of the crushing box. Because one of the driving gears is fixed to the large belt wheel, the large belt wheel drives the small belt wheel to rotate through the belt, and the small belt wheel drives the paddle blade to rotate through the stirring rod. The paddle blade can break up the crushed organic fertilizer and fully stir it, so that various raw materials in the organic fertilizer can be fully mixed. The diameter of the large belt wheel is larger than the diameter of the small belt wheel, so that the rotation speed of the stirring rod and the paddle blade is greater than that of the crushing roller, further improving the mixing effect. In addition, the entire crushing and mixing process of the fertilizer is carried out inside the device, and the exhaust valve on the top of the crushing box can discharge the gas to the external purification equipment to prevent the spread of odor and affect the processing environment.

[0022] 3. The present invention adds crushed organic fertilizer into a mixing box, and the paddles can mix the organic fertilizer. When the humidity of the organic fertilizer inside the mixing box needs to be adjusted, the solenoid valve is opened to allow the liquid inside the collecting box to enter the mixing box through the solenoid valve, and the fertilizer is stirred with the paddles, thereby conveniently adjusting the humidity of the organic fertilizer. There is no need to move the fertilizer out of the device and then adjust its humidity, thereby improving the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

The material pusher assembly 8 includes a tapered shaft 801, which is installed in the barrel 601.

One side of the driven wheel 805 is fixed to the end of the rotating rod 9, and the driving wheel 804 is connected to the driven wheel 805 through a transmission belt.

[0039] When working, the spiral extrusion piece 802 can squeeze the shredded fertilizer while conveying the organic fertilizer. Because the thread pitch on the spiral extrusion piece 802 decreases step by step from right to left, the spiral extrusion piece 802 can squeeze the shredded fertilizer while conveying the organic fertilizer, which is convenient for squeezing out the water in the fertilizer. The squeezed water can leak out through the water filter hole 603 outside the barrel 601 and be collected in the collection box 5, so that the water in the fertilizer can be squeezed out and collected independently. The spiral extrusion piece 802 can grind the organic fertilizer and convey it during the rotation process.

[0040] Telescopic components 10 are fixed on both sides of the outer wall of the rotating rod 9, and the telescopic component 10 includes a sleeve 101. The end of the sleeve 101 is fixed on the outside of the rotating rod 9. A knocking block 103 is sleeved in the sleeve 101.

[0042] The first transmission wheel 12 is connected to the second transmission wheel 13 through a transmission belt, a scattering assembly 14 is fixed in the middle of the second transmission wheel 13, the second transmission wheel 13 is transmission-connected to the second transmission wheel 12 through a transmission belt, the scattering assembly 14 is installed in the crushing box 3, and the scattering assembly 14 includes a transmission gear 141, a rotating shaft 142 is fixed to one side of the transmission gear 141, and a scattering piece 143 is fixed outside the rotating shaft 142. During operation, when the organic fertilizer falls into the crushing box 3, the transmission gear 141 drives the scattering piece 143 to rotate through the rotating shaft 142, and the scattering piece 143 can scatter the fallen organic fertilizer, which is conducive to improving the subsequent crushing effect.

[0043] Two crushing rollers 16 are provided below the scattering assembly 14, and the crushing rollers 16 are installed below the inner wall of the crushing box 3, and the scattering pieces 143 are located above the two crushing rollers 16. A driving gear 17 is fixed to the end of the crushing roller 16, and the two driving gears 17 are meshed with each other, and a motor 15 is fixed to one side of one of the driving gears 17 and is meshed and connected with a transmission gear 141 in the scattering assembly 14 on the outside, and the motor 15 is installed on the supporting legs 2 and the crushing box 3, and a mixing assembly 18 is fixed to the end of the other driving gear 17, and a mixing box 19 is provided outside the mixing assembly 18.

[0044] The mixing assembly 18 includes a large belt pulley 181, one side of which is fixed to the driving gear 17, and the large belt pulley 181 is connected to a small belt pulley 182 through a belt, and a stirring rod 183 is fixed to one side of the small belt pulley 182, and a plurality of paddles 184 are provided outside the stirring rod 183, and the paddles 184 are located in the mixing box 19.

[0045] The opening at the top of the mixing box 19 corresponds to the opening at the bottom of the crushing box 3 . A discharge valve 20 is installed at the bottom of the mixing box 19 . A solenoid valve 7 is installed at the bottom of the collecting box 5 . The solenoid valve 7 is connected to the top of the mixing box 19 .

[0046] During operation, the control motor 15 is operated to drive the driving gear 17 to rotate, and the driving gear 17 drives the second transmission wheel 13 to rotate through the transmission gear 141. The second transmission wheel 13 drives the first transmission wheel 12 and the tapered shaft 801 in the pushing assembly 8 to rotate through the transmission belt, and the tapered shaft 801 drives the spiral extrusion sheet 802 to work. Because the driving gear 17 is fixed to the crushing roller 16, and because one of the driving gears 17 is connected to the belt pulley 181 in the mixing assembly 18, the crushing roller 16 can run synchronously with the pushing assembly 8 and the mixing assembly 18, thereby improving its working stability and reducing its use cost.

[0047] By opening the electromagnetic valve 7, the liquid stored in the collecting box 5 can enter the mixing box 19, and the fertilizer in the mixing box 19 is stirred in cooperation with the mixing component, so as to facilitate the adjustment of the humidity of the organic fertilizer.

[0048] When working, the paddle 184 can break up the crushed organic fertilizer and fully stir it, so that the various raw materials in the organic fertilizer can be fully mixed; the diameter of the large belt pulley 181 is larger than the diameter of the small belt pulley 182, so that the rotation speed of the stirring rod 183 and the paddle 184 is greater than the crushing roller 16, so that the paddle 184 can quickly mix the fertilizer, further improving the mixing effect.

[0049] A method for using a crushing device for organic fertilizer fermentation pretreatment, the method comprising the following steps:

[0050] When the organic fertilizer is crushed, some small-volume dry materials are directly added into the crushing box 3 from the feed pipe 4, and wet organic fertilizers are added into the barrel 601 from the hopper 602. The motor 15 is controlled to drive the driving gear 17 to rotate, and the driving gear 17 drives the second transmission wheel 13 to rotate through the transmission gear 141. The second transmission wheel 13 drives the first transmission wheel 12 and the connecting shaft 803 to rotate through the transmission belt, and the connecting shaft 803 drives the conical shaft 801 and the spiral extrusion piece 802 to rotate. The spiral extrusion piece 802 can grind the organic fertilizer during the rotation process and transport the organic fertilizer to the left. Because the thread pitch on the spiral extrusion piece 802 is from right to left, the spiral extrusion piece 802 can grind the organic fertilizer and transport it to the left. It decreases step by step to the left, so that the spiral extrusion piece 802 can push the fertilizer from the position with large spiral pitch to the position with small spiral pitch, thereby achieving the purpose of squeezing the fertilizer, so that the spiral extrusion piece 802 can squeeze the minced fertilizer while conveying the organic fertilizer, and the squeezed water can leak out through the water filter hole 603 outside the barrel 601 and be collected in the collection box 5. Because the ferrule 604 is installed at the end of the barrel 601, and there is a gap between the ferrule 604 and the tapered shaft 801, the spiral extrusion piece 802 can push the fertilizer into the gap and detach from the barrel 601 when conveying the fertilizer, and the squeezed organic fertilizer falls into the crushing box 3 from the ferrule 604 at the end of the barrel 601.

[0051] At the same time, the connecting shaft 803 will drive the driving wheel 804 to rotate, and the driving wheel 804 will drive the driven wheel 805 to rotate through the transmission belt, and the driven wheel 805 will drive the rotating rod 9 and the two telescopic components 10 to rotate clockwise. The knocking block 103 in the telescopic component 10 can contact the inclined surface of the block 11 during the movement, and the knocking block 103 can slide in the sliding sleeve 101 and squeeze the spring 102 during the pressure. When the knocking block 103 is separated from the knocking block 103, the knocking block 103 is supported by the elastic force of the spring 102, so that the knocking block 103 can be quickly extended and knock the barrel 601. During the rotation of the knocking block 103, the barrel 601 can be continuously knocked. During the vibration of the barrel 601, the residue in the water filter hole 603 can be shaken out to prevent the spiral extrusion sheet 802 from squeezing and conveying the fertilizer and causing blockage in the water filter hole 603.

[0052] When the organic fertilizer falls into the crushing box 3, the transmission gear 141 drives the scattering piece 143 to rotate through the rotating shaft 142. The scattering piece 143 can scatter the fallen organic fertilizer, which is beneficial to improving the subsequent crushing effect. Because the two driving gears 17 are meshed with each other, the two driving gears 17 respectively drive the two crushing rollers 16 to rotate relatively and crush the organic fertilizer. The crushed organic fertilizer falls into the mixing box 19 through the opening at the bottom of the crushing box 3. Because one of the driving gears 17 is fixed to the large belt wheel 181, the large belt wheel 181 drives the small belt wheel 182 to rotate through the belt, and the small belt wheel 182 drives the paddle 184 to rotate through the stirring rod 183. The paddle 184 can scatter the crushed organic fertilizer and fully stir it, so that various raw materials in the organic fertilizer can be fully mixed.

[0053] When it is necessary to adjust the humidity of the organic fertilizer inside the mixing box 19, the solenoid valve 7 is opened to allow the liquid stored in the collecting box 5 to enter the mixing box 19 to adjust the humidity of the organic fertilizer. After completing the stirring of the organic fertilizer, the discharge valve 20 at the bottom of the mixing box 19 is opened to discharge the fertilizer, thereby completing the fermentation pretreatment of the organic fertilizer.

7. The pulverizing device for organic fertilizer fermentation pretreatment according to claim 1, characterized in that: The mixing assembly (18) comprises a large belt pulley (181), wherein the large belt pulley (181) is connected to a small belt pulley (182) via a belt, a stirring rod (183) is fixed to one side of the small belt pulley (182), a plurality of paddles (184) are arranged outside the stirring rod (183), and the paddles (184) are located in a mixing box (19).

8. A method for using a pulverizing device for organic fertilizer fermentation pretreatment, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: When the organic fertilizer is crushed, part of the dry material with a small volume is directly added into the crushing box (3) from the feeding pipe (4), and the wet organic fertilizer is added into the barrel (601) from the hopper (602). The motor (15) is controlled to work so as to drive the driving gear (17) to rotate. The driving gear (17) drives the second transmission wheel (13) to rotate through the transmission gear (141). The second transmission wheel (13) drives the first transmission wheel (12) and the connecting shaft (803) to rotate through the transmission belt. The connecting shaft (803) drives the conical shaft (801) and the spiral extrusion sheet (802) to rotate. The spiral extrusion sheet (802) can crush the organic fertilizer during the rotation process and transport the organic fertilizer to the left. Due to the thread gap on the spiral extrusion sheet (802), the organic fertilizer can be crushed and transported to the left. The pitch decreases step by step from right to left, so that the spiral extrusion piece (802) can push the fertilizer from the position with large spiral pitch to the position with small spiral pitch, so as to achieve the purpose of extruding the fertilizer, so that the spiral extrusion piece (802) can squeeze the crushed fertilizer while conveying the organic fertilizer, and the squeezed water can leak out through the water filter hole (603) outside the barrel (601) and be collected in the collection box (5). Because the ferrule (604) is installed at the end of the barrel (601), and there is a gap between the ferrule (604) and the conical shaft (801), the spiral extrusion piece (802) can push the fertilizer into the gap and detach from the barrel (601) when conveying the fertilizer, and the squeezed organic fertilizer falls into the crushing box (3) from the ferrule (604) at the end of the barrel (601); At the same time, the connecting shaft (803) drives the driving wheel (804) to rotate, and the driving wheel (804) drives the driven wheel (805) to rotate through the transmission belt, and the driven wheel (805) drives the rotating rod (9) and the two telescopic components (10) to rotate clockwise. The knocking block (103) in the telescopic component (10) can contact the inclined surface part of the stopper (11) during the movement process, and the knocking block (103) can slide in the sliding sleeve (101) and compress the spring (102) during the pressure process. When (103) is separated from the knocking block (103), the knocking block (103) is supported by the elastic force of the spring (102), so that the knocking block (103) can be quickly extended and knock the barrel (601). The knocking block (103) can continuously knock the barrel (601) during rotation, and the residue in the water filter hole (603) can be shaken out during the vibration of the barrel (601), thereby preventing the spiral extrusion sheet (802) from causing blockage of the water filter hole (603) during the process of extruding and conveying fertilizer; When the organic fertilizer falls into the crushing box (3), the transmission gear (141) drives the scattering piece (143) to rotate through the rotating shaft (142), and the scattering piece (143) can scatter the fallen organic fertilizer, which is beneficial to improving the subsequent crushing effect. Because the two driving gears (17) are meshed with each other, the two driving gears (17) respectively drive the two crushing rollers (16) to rotate relatively and crush the organic fertilizer. The crushed organic fertilizer falls into the mixing box (19) through the opening at the bottom of the crushing box (3). Because one of the driving gears (17) is fixed to the large belt wheel (181), the large belt wheel (181) drives the small belt wheel (182) to rotate through the belt, and the small belt wheel (182) drives the paddle (184) to rotate through the stirring rod (183). The paddle (184) can scatter the crushed organic fertilizer and fully stir it, so that various raw materials in the organic fertilizer can be fully mixed. When the humidity of the organic fertilizer in the mixing box (19) needs to be adjusted, the solenoid valve (7) is opened to allow the liquid stored in the collecting box (5) to enter the mixing box (19) so as to adjust the humidity of the organic fertilizer. After the stirring of the organic fertilizer is completed, the discharge valve (20) at the bottom of the mixing box (19) is opened to discharge the fertilizer, thereby completing the fermentation pretreatment of the organic fertilizer.
