Description

Technical Field

[0001] The invention relates to the technical field of fertilizer fermentation, and in particular to a straw recovery composting fermentation device. Background Art

[0002] With the development of agriculture, a large amount of crop straw is produced every year. According to statistics, the average comprehensive utilization rate of agricultural waste is less than 40%, and more than 60% of by-products are abandoned in nature, or burned or naturally decayed, polluting the environment. This is equivalent to the input and output of 700 million mu of land and 600 billion yuan of income being lost in vain, and it has caused a serious environmental crisis and restricted the advancement of new rural construction. In order to reduce the environmental pollution of crop straw and the rational use of resources, we use composting and fermentation to return crop straw to the field, which not only reduces pollution to the environment, but also reduces the use of fertilizers and saves costs.

[0003] The traditional straw composting method is to dig pits directly in the field. The straw needs to be moistened during the composting process, and the humidity and uniformity of the straw greatly affect the quality and efficiency of composting fermentation. In the traditional method, the straw is piled up and then watered, which is prone to local high humidity and uneven humidity. In addition, the efficiency of penetrating all the straw from top to bottom through the gaps between the straw is low, affecting the fermentation process.

DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] like Figure 1-Figure 8 As shown, this embodiment proposes a straw recovery composting fermentation device, including a fermentation tank and a crushing box 6. The crushing box 6 is slidably connected to a discharge box 2 located above the fermentation tank. The discharge box 2 can only slide in the vertical direction. The crushing box 6 is fixed to the ground by a bracket. A filter screen 5 is arranged between the crushing box 6 and the discharge box 2. The filter screen 5 and the crushing box 6 are detachably connected, so as to facilitate the maintenance and replacement of the filter screen 5. The filter screen 5 is connected to a vibrator, so as to facilitate the screening of the material.

[0024] The discharge box 2 is connected to a plurality of spray guns 1, which are located above the fermentation tank. The spray guns 1 can spray water, and the crushing box 6 crushes the straw. After crushing, the materials with qualified sizes fall into the discharge box 2 through the filter screen 5, and then fall into the fermentation tank from the discharge box 2. At the same time, the spray guns 1 spray water, so that the crushed materials discharged from the discharge box 2 are directly mixed with water to form wet materials. One of the spray guns 1 can spray the accelerator. After the wet materials are piled up, a layer of the accelerator is sprayed to form a fermentation pile, thereby fermenting the fertilizer.

[0025] A rotating shaft 7 is rotatably connected inside the crushing box 6. The rotating shaft 7 is arranged in a vertical direction and can only rotate. A crushing knife 8 and a spoiler rod 13 are fixedly connected to the rotating shaft 7. There are several crushing knives 8, and several crushing knives 8 are arranged in a staggered manner. The crushing knives 8 are arranged in a horizontal direction, so that when the rotating shaft 7 rotates, it can drive several crushing knives 8 to rotate at the same time, so as to better realize the crushing of straw. The spoiler rod 13 is fixedly connected to the bottom end of the rotating shaft 7, and the spoiler rod 13 is arranged above the filter screen 5. The spoiler rod 13 can stir the material close to the filter screen, so as to achieve a better mixing effect.

[0026] The spoiler rod 13 is provided with a sliding hole, in which an auxiliary knife 16 that can be moved out of the spoiler rod 13 is slidably connected. The auxiliary knife 16 is connected to the spoiler rod 13 through a compression spring. The auxiliary knife 16 is arranged in a vertical direction, and the compression spring is sleeved on the auxiliary knife 16. One end of the compression spring is connected to the auxiliary knife 16, and the other end is connected to the spoiler rod 13. In the initial state, under the elastic force of the compression spring, the auxiliary knife 16 is located in the sliding hole. When the auxiliary knife 16 moves out of the sliding hole and is reset under the action of the compression spring, the sliding hole can clean the spoiler rod 13.

[0027] The discharge box 2 is connected to the crushing box 6 via a first spring. The discharge box 2 is fixedly connected with a fixing rod 12. The crushing box 6 is fixedly connected with an electromagnet 3 which has an attraction effect on the fixing rod 12. The magnetic force of the electromagnet 3 is greater than the elastic force of the first spring.

[0028] The crushing box 6 is fixedly connected to the support rod, the first spring is sleeved on the support rod, the upper end of the first spring is connected to the discharge box 2, and the lower end is connected to the crushing box 6, the electromagnet 3 is fixedly connected to the support rod, the electromagnet 3 is located on one side of the first spring, and the fixed rod 12 is slidably connected to the support rod.

[0029] As the fixed rod 12 moves, the distance between the fixed rod 12 and the electromagnet 3 is appropriate, and when the electromagnet 3 is energized, the electromagnet 3 can attract the fixed rod 12 to continue to descend, thereby attracting the discharge box 2 to continue to descend, so that the first spring continues to be compressed.

[0030] The discharge box 2 is connected to a discharge pipe, which is rotatably connected to a valve plate 15. The discharge box 2 is connected to a motor 14, which can drive the valve plate 15 to rotate so as to open or block the discharge pipe. When the valve plate 15 is in a horizontal state, the discharge pipe is in a blocked state, and the motor drives the valve plate 15 to rotate to realize discharge.

[0031] The crushing box 6 is connected to a switch 4 located above the electromagnet 3. The fixing rod 12 can touch the switch 4 to make the electromagnet 3 and the motor 14 work. The switch 4 can be a proximity switch. When the fixing rod 12 moves to one side of the switch 4, the switch 4 transmits mutual signals to the controller.

[0032] A feed box can also be connected to the upper end of the crushing box 6, and a switch plate is rotatably connected inside the feed box. The switch plate is connected to a drive motor, and the drive motor can drive the switch plate to rotate to realize feeding. The switch 4 can make the drive motor work at the same time. When the discharge box 2 is discharging material, the crushing box 6 is feeding.

[0033] The proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When the fixed rod 12 approaches the sensing surface of the proximity switch to the action distance, the switch can be activated without mechanical contact or applying any pressure, thereby providing control instructions to the controller. The controller controls the electromagnet 3 and the motor 14 to work. At this time, the electromagnet 3 attracts the discharge box 2 to continue to descend, and the motor 14 drives the valve plate 15 to open to realize discharge, and the drive motor drives the switch plate to rotate to realize feeding.

[0034] The two ends of the spoiler rod 13 are slidably connected with wedge blocks 18 that move horizontally. The wedge blocks 18 are in contact with the auxiliary knife 16. The rotating shaft 7 is slidably connected with a lifting rod 9. The lifting rod 9 is connected to the rotating shaft 7 through a fifth spring. The lifting rod 9 is hinged to the wedge block 18 through a connecting rod 17. One end of the connecting rod 17 is hinged to the lifting rod 9, and the other end of the connecting rod 17 is hinged to the wedge block 18. When the lifting rod 9 rises, the wedge blocks 18 on both sides can be driven to move inward at the same time through the connecting rod 17, and the wedge block 18 can press down the auxiliary knife 16 to move the auxiliary knife 16 out of the spoiler rod 13.

[0035] The outer wall of the crushing box 6 is fixedly connected with a guide rod 21 arranged in the vertical direction, and the guide rod 21 is slidably connected with a lifting plate 10 that moves in the vertical direction. The lifting rod 9 and the lifting plate 10 are rotatably connected. When the lifting rod 9 rises, the auxiliary knife 16 can be driven by the wedge block 18 to move downward to remove the spoiler rod 13. The lifting plate 10 can only slide in the vertical direction. The lifting plate 10 can drive the lifting rod 9 to rise, and the rotating shaft 9 can drive the lifting rod 9 to rotate. At this time, the lifting rod 9 rotates around the lifting plate 10.

[0036] The crushing box 6 is connected to a motor 28 that can drive the rotating shaft 7 to rotate. The motor 28 is connected to a driving shaft. The driving shaft fixing sleeve is provided with a first pulley and a single-tooth gear 25. The rotating shaft 7 fixing sleeve is provided with a second pulley. The first pulley and the second pulley sleeve are provided with a synchronous belt. Therefore, the motor 28 can drive the rotating shaft 7 and the single-tooth gear 25 to rotate at the same time. The crushing box 6 is rotatably connected to a passive gear 24. The passive gear 24 and the single-tooth gear 25 are meshed. The passive gear 24 is connected to a cam that can drive the lifting plate 10 to rise.

[0037] The passive gear 24 is provided with a wedge-shaped annular groove, and the crushing box 6 is slidably connected with a reset rod 11 that moves in the vertical direction. The reset rod 11 is connected to the crushing box 6 through a second spring, and the passive gear 24 is connected to the crushing box 6 through a coil spring 26. The reset rod 11 and the passive gear 24 are slidably connected. The reset rod 11 is connected with a constraint rod 27 through a third spring, and the constraint rod 27 is slidably set in the wedge-shaped annular groove.

[0038] The third spring is sleeved on the reset rod 11, one end of the third spring is connected to the reset rod 11, and the other end of the third spring is connected to the constraint rod 27. Under the elastic force of the third spring, the constraint rod 27 always slides in the wedge-shaped ring groove. When the single-tooth gear 25 drives the passive gear 24 to rotate, the setting of the wedge-shaped ring groove can make the passive gear 24 rotate in only one direction, and at this time the coil spring 26 is deformed.

[0039] The guide rod 21 is provided with a card slot 19, and the lifting plate 10 is slidably connected with a card rod 20 that can slide into the card slot 19. The card rod 20 is connected to the lifting plate 10 through a fourth spring. The reset rod 11 is connected with a magnet 22 that has an attractive effect on the card rod 20, and the magnetic force of the magnet 22 is greater than the elastic force of the fourth spring.

[0040] The fourth spring is sleeved on the card rod 20, one end of the fourth spring is connected to the card rod 20, and the other end of the fourth spring is connected to the lifting plate 10. Under the elastic force of the fourth spring, the card rod 20 can slide into the card slot 19 to limit the height of the lifting plate 10. When the magnet 22 moves to one side of the card rod 20, the magnetic force of the magnet 22 can make the card rod 20 move out of the card slot 19. At this time, under the action of gravity, the lifting plate 10 descends.

[0041] The lifting plate 10 is rotatably connected to a pendulum block 23, and the lifting plate 10 is fixedly connected to a limit block. The limit block is located on one side of the pendulum block 23 so that the pendulum block 23 can only rotate in one direction. When the cam and the pendulum block 23 are in contact, the pendulum block 23 cannot rotate due to the setting of the limit block. The lifting plate 10 can be driven to rise by the pendulum block 23. When the cam jumps over the pendulum block 23 to reset, the cam can drive the pendulum block 23 to rotate around the lifting plate 10, so that the cam can be reset normally.

[0042] When the electromagnet 3 attracts the discharge box 2 to continue to descend, it can drive the discharge box 2 to pull the reset rod 11 downward, so that the constraint rod 27 moves out of the wedge-shaped ring groove, and the reset rod 11 can drive the constraint rod 27 to release the limit on the passive gear 24, so that the coil spring 26 drives the passive gear 24 to reset, realizing the automatic reset work of the device after discharging, so as not to affect the next work, with a high degree of automation and no need for manual intervention. A method for using a straw recycling composting and fermentation device, using the above-mentioned straw recycling composting and fermentation device, comprises the following steps: S1: The motor 28 drives the rotating shaft 7, and the rotating shaft 7 drives the crushing knife 8 to rotate, so as to crush the straw in the crushing box 6. The crushed straw falls into the discharge box 2 through the filter 5. As the crushed straw increases, the discharge box 2 moves downward, compressing the first spring. At the same time, the motor 28 drives the driven gear 24 to rotate through the single-tooth gear 25, and the constraint rod 27 slides in the wedge-shaped ring groove. Under the action of the constraint rod 27, the driven gear 24 is prevented from reversing, and the coil spring 26 is deformed at this time; S2: When the discharge box 2 drops to the point where the fixed rod 12 moves to the side of the switch 4, the discharge box 2 is in contact with the lower end of the reset rod 11, and the switch 4 makes the electromagnet 3 and the motor 14 work, and the motor 14 drives the valve plate 15 to rotate, so that the material in the discharge box 2 falls into the fermentation tank; At the same time, after the electromagnet 3 is energized, the fixed rod 12 is attracted, so that the discharge box 2 continues to descend. At this time, the discharge box 2 drives the reset rod 11 to continue to descend, the constraint rod 27 moves out of the wedge-shaped ring groove, and the coil spring 26 drives the passive gear 24 to reset. At the same time, the crushing box 6 is fed, and a new round of straw crushing work is carried out; When the discharge box 2 does not reach the specified weight within the specified time, the specified time is the time required for the passive gear 24 to drive the cam to move to contact the swing block 23, and the specified weight refers to the weight of the discharge box 2 at this time, which can drive the fixed rod 12 to cooperate with the switch 4. As the passive gear 24 continues to rotate, the cam drives the lifting plate 10 to rise, so that the clamping rod 20 is clamped into the clamping slot 19; S11: The lifting plate 10 drives the lifting rod 9 to rise, the lifting rod 9 drives the wedge block 18 to move, and the wedge block 18 drives the auxiliary knife 16 to move out of the spoiler rod 13, so as to further crush the material above the filter screen 5, and then the crushed qualified material falls into the discharge box 2; S12: When the discharge box 2 descends to the point where the fixed rod 12 moves to the side of the switch 4, the discharge box 2 is in contact with the lower end of the reset rod 11, and the switch 4 makes the electromagnet 3 and the motor 14 work, and the motor 14 drives the valve plate 15 to rotate, so that the material in the discharge box 2 falls into the fermentation tank; At the same time, after the electromagnet 3 is energized, it attracts the fixed rod 12, causing the discharge box 2 to continue to descend. At this time, the discharge box 2 drives the reset rod 11 to continue to descend, the constraint rod 27 moves out of the wedge-shaped ring groove, and the coil spring 26 drives the passive gear 24 to reset; at the same time, the reset rod 11 drives the magnet 22 to descend, the magnet 22 drives the clamping rod 20 to move out of the clamping groove 19, the compression spring drives the reset knife to reset and move into the spoiler rod 13, the crushing box 6 is fed, and a new round of straw crushing work is carried out; because the height of the lifting plate 10 is increased at this time, the magnet 22 can just move to the side of the clamping rod 20.
