Description

Technical Field

[0001] This invention relates to the field of fertilizer fermentation technology, and in particular to an unloading device for an organic fertilizer fermentation tank. Background Technology

[0002] In the aerobic fermentation process of organic fertilizer, box-type fermentation equipment has become one of the mainstream equipment for organic fertilizer composting due to its characteristics such as closed and controllable fermentation environment, high space utilization, and ease of large-scale continuous production. In order to use the material's own weight to achieve unloading, the bottom of the fermentation box is generally designed as a conical narrowing structure with a discharge port at the bottom. After fermentation, the organic fertilizer material is guided by the conical hopper and discharged from the discharge port. However, in the actual unloading process, the composted organic fertilizer material contains a large amount of organic fiber and usually retains a certain moisture content. The material particles have strong adhesion. At the narrowing section of the conical section, they are easily squeezed to form a stable material arch structure, commonly known as the "bridging" phenomenon. After the material arch is formed, it will block the material's falling channel, resulting in a significant decrease in the unloading rate or even complete interruption, which seriously affects the continuous operation efficiency of the fermentation production line.

[0003] To address the problem of material arching and blockage, conventional methods for breaking up arches in existing fermentation tanks typically involve setting up a rotating arch-breaking shaft at the central axis of the discharge port, and installing stirring blades or scrapers on the shaft. The material is disturbed by the rotation of the central rotating component to break up the material arches.

[0004] For some sticky organic fertilizer materials, the adhesion between the material and the inner wall of the fermentation tank is greatly improved after drying. The resulting material arch base is firmly adhered to the inner wall of the cone, and the overall structure is extremely stable. Traditional central arch-breaking equipment can only act on the central area of ​​the material arch and cannot reach and destroy the arch base structure located on the inner wall. During operation, it can only disperse the central part of the material arch. The remaining inner wall arch base will gather the material again in a short time to form a new material arch. The arch-breaking effect is extremely poor and often requires frequent shutdowns for manual unblocking during production. Summary of the Invention

[0005] One objective of this invention is to provide an unloading device for an organic fertilizer fermentation box. This invention arranges the core arch-breaking component along the inner wall of the unloading channel, avoiding the central flow area of ​​the unloading port, effectively preventing the arch-breaking structure itself from hindering the unloading efficiency. It also features a graded vibration mechanism to further enhance the arch-breaking and unloading effect through complementary internal and external synergistic vibration.

[0008] Preferably, the main arch-breaking arm is hollow in design and a vertical part is fixedly welded to the top of the main arch-breaking arm. A rod is movably inserted into the main arch-breaking arm and is coaxial with the main arch-breaking arm. A first spring is fixedly connected between the end of the rod and the main arch-breaking arm. A conical column is movably inserted into the vertical part of the main arch-breaking arm, and a through hole is opened at the bottom of the vertical part corresponding to the end of the conical column. A second spring is fixedly connected between the conical column and the vertical part of the main arch-breaking arm. Under the elastic force of the first spring, one end of the rod abuts against the conical surface of the conical column. A conical spike is horizontally movably inserted into the arch-breaking arm. A third spring is fixedly connected between one end of the conical spike and the arch-breaking arm. A groove is opened on the conical spike and the rod passes through the groove on the conical spike. A frustum is provided on the rod corresponding to the groove of the conical spike. A through hole is opened on the main arch-breaking arm corresponding to the position of the conical spike.

[0009] Preferably, the ends of the multiple arch-breaking supports that are away from the main arch-breaking arm are on the same vertical plane, and the distance from this plane to the axis of the spiral tube is equal to the radius of the spiral tube.

[0010] Preferably, the first vibration tapping assembly includes a torsion spring seat, a dial wheel, and a first vibration tapping seat. The torsion spring seat and the first vibration tapping seat are both fixedly installed on the outer end of the fermentation chamber. The dial wheel is rotatably installed on the outer end of the fermentation chamber. The vibration tapping wheel is fixedly installed on the rotating shaft of the torsion spring seat. The dial wheel rotates to intermittently tap the vibration tapping wheel. When the vibration tapping wheel returns to its original position, it taps the first vibration tapping seat.

[0011] Preferably, the vibrating wheel has an integrally formed protrusion and a striking head that contact the dial wheel, the length of the protrusion is less than the centrifugal length of the striking head, and the first vibrating seat is triangular.

[0012] Preferably, a bevel gear disc is rotatably installed inside the fermentation chamber, and the bottom of the bevel gear disc is fixedly connected to the main arm of the arch-breaking device.

[0015] The beneficial effects of this invention are: The organic fertilizer fermentation tank unloading device proposed in this invention, by arranging the main arch-breaking arm inclined along the inner wall of the fermentation tank cone and driving it to revolve, allows the arch-breaking operation area to directly cover the inner wall adhesion layer that is most likely to form a stable arch base, thereby destroying the supporting structure of the material arch from the root. The cone-shaped spike rod achieves high-frequency reciprocating extension and contraction under the cooperation of the toothed ring and the spring mechanism, forming a continuous and powerful mechanical piercing of the arch base. The arch breaking is highly targeted and has a long-lasting effect. At the same time, the combination of high-frequency side wall vibration triggered by the rotation linkage of the main arch-breaking arm and low-frequency heavy impact constitutes a composite vibration field with complementary frequency and energy, which can effectively loosen material arches of different shapes and degrees of adhesion, significantly improving the thoroughness and adaptability of arch breaking. The entire device sets the core arch-breaking component on the side of the unloading channel, completely avoiding the central material discharge area, ensuring the smooth flow of material while efficiently breaking the arch, and achieving simultaneous optimization of arch breaking and unloading efficiency.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] refer to Figures 1-10 This invention discloses an unloading device for an organic fertilizer fermentation tank, comprising a fermentation tank body 1, as shown in the reference. Figure 1 and Figure 2 The fermentation chamber 1 has a discharge port at its bottom, and the lower half of the fermentation chamber 1 is conical. A breaker seat 2 is fixedly installed at the discharge port of the fermentation chamber 1. A breaker main arm 3 extending into the fermentation chamber 1 is fixedly installed on the inner surface of the breaker seat 2. The breaker main arm 3 is zigzag-shaped and its inclination is the same as the taper of the fermentation chamber 1. Multiple horizontally arranged breaker support arms 302 are fixedly welded to the breaker main arm 3 at equal intervals. Multiple conical supports facing the inner wall of the fermentation chamber 1 are movably inserted into the breaker main arm 3. The spike rod 306 and the toothed ring 101 are fixedly installed inside the fermentation box 1. The arch-breaking main arm 3 rotates above the toothed ring 101 to drive the spike rod 306 to extend and retract at high frequency to pierce the arch base on the fermentation box 1. It also includes a number of first vibration components 4 installed in a ring array on the fermentation box 1, and a second vibration component 5 installed on the arch-breaking seat 2. The first vibration component 4 lightly strikes the fermentation box 1 at high frequency to generate vibration, and the second vibration component 5 heavily strikes the fermentation box 1 at low frequency to generate vibration. The main arch-breaking arm 3 is arranged obliquely along the inner wall of the cone of the fermentation box 1, and its orbital trajectory is close to the inner wall area, which can directly act on the arch base formed by the material and the inner wall of the box. The high-frequency low-amplitude vibration generated by the first vibration component 4 and the low-frequency high-amplitude vibration generated by the second vibration component 5 are combined to form a composite vibration field with complementary frequency and energy, which works synergistically from the side wall and bottom of the box to effectively loosen and destroy the material arch structure of different shapes.

[0028] refer to Figure 3 and Figure 4 Flange covers 201 are fixedly installed on the top and bottom of the arch-breaking seat 2. The arch-breaking seat 2 is fixedly connected to the discharge port of the fermentation tank 1 through one of the flange covers 201. A semi-circular sliding ring sleeve 202 is fixedly installed between the two flange covers 201. A driven gear 203 is fixedly fitted on the outer side of the two sliding ring sleeves 202. A drive gear 204 driven by a motor is installed on one of the flange covers 201. The drive gear 204 is meshed with the driven gear 203. A spiral tube 205 is rotatably clamped between the two sliding ring sleeves 202. The arch-breaking main arm 3 is fixedly installed on the inner circular surface of the spiral tube 205. The drive gear 204 drives the arch-breaking main arm 3 to revolve around the axis of the spiral tube 205 to achieve arch breaking. The drive gear 204 rotates under the drive of the motor, which drives the driven gear 203 meshing with it to rotate. The driven gear 203 drives the internal spiral tube 205 and the main arch-breaking arm 3 on it to revolve around the axis of the spiral tube 205 through the slip ring sleeve 202. This rotation drive mechanism is set on the side of the unloading channel, so that the main arch-breaking arm 3 rotates in the area close to the inner wall, completely avoiding the central unloading channel of the unloading port, and avoiding the arch-breaking component itself from obstructing the falling of materials.

[0029] refer to Figure 5 and Figure 6 The main arch-breaking arm 3 is hollow in design, with a vertical section fixedly welded to its top. A rod 301 is movably inserted into the main arch-breaking arm 3, and the rod 301 is coaxial with the main arch-breaking arm 3. A first spring 303 is fixedly connected between the end of the rod 301 and the main arch-breaking arm 3. A conical column 304 is movably inserted into the vertical section of the main arch-breaking arm 3, and a through hole is opened at the bottom of the vertical section corresponding to the end of the conical column 304. A second spring 305 is fixedly connected between the conical column 304 and the vertical section of the main arch-breaking arm 3. Under the elastic force of the first spring 303, the rod 301... The cone end abuts against the cone surface of the cone column 304. A cone spike rod 306 is horizontally and movably inserted into the arch-breaking support arm 302. A third spring 307 is fixedly connected between one end of the cone spike rod 306 and the arch-breaking support arm 302. A groove is opened on the cone spike rod 306 and the insertion rod 301 passes through the groove on the cone spike rod 306. A frustum is provided on the insertion rod 301 at the position corresponding to the groove of the cone spike rod 306. A through hole is opened on the main arch-breaking arm 3 at the position corresponding to the cone spike rod 306. A toothed ring 101 is located directly below the cone column 304. The top of the toothed ring 101 is integrally formed with multiple toothed protrusions in a ring array. When the main arm 3 of the arch-breaking mechanism rotates above the toothed ring 101, the bottom end of the cone 304 intermittently contacts the teeth on the toothed ring 101. When the cone 304 is pushed into the recess between the two teeth by the elastic force of the second spring 305, its conical surface pushes the insert rod 301 in contact with it to compress the first spring 303 inside the main arm 3 of the arch-breaking mechanism. When the insert rod 301 moves inward, the spike rod 306 is quickly ejected outward under the elastic force of the third spring 307, piercing the inner wall of the fermentation chamber 1. To destroy the arch base adhered to it, after the cone column 304 is pressed back by the protruding teeth, the insertion rod 301 is reset under the action of the first spring 303, and its cone part is re-locked into the groove of the cone spike rod 306, pulling the cone spike rod 306 back into the arch-breaking support arm 302, completing one extension and retraction cycle. The continuous rotation of the arch-breaking main arm 3 causes multiple cone spike rods 306 to reciprocate and extend at high frequency, forming a continuous piercing and destruction of the inner wall arch base. It is worth noting that the elastic force of the second spring 305 is much greater than the elastic force of the first spring 303, otherwise it would be impossible to push the insertion rod 301 to retract. Multiple arch-breaking support arms 302 are on the same vertical plane at the ends away from the main arch-breaking arm 3, and the distance from this plane to the axis of the spiral tube 205 is equal to the radius of the spiral tube 205. This structural design ensures that the line connecting the ends of the multiple arch-breaking support arms 302 forms a virtual cylindrical surface coaxial with the cone section of the fermentation box 1, and this cylindrical surface is exactly the same as the width of the unloading channel to prevent affecting the unloading. refer to Figure 7 and Figure 8The first vibration component 4 includes a torsion spring seat 401, a dial wheel 403, and a first vibration seat 404. The torsion spring seat 401 and the first vibration seat 404 are both fixedly installed on the outer end of the fermentation box 1. The dial wheel 403 is rotatably installed on the outer end of the fermentation box 1. A vibration wheel 402 is fixedly installed on the rotating shaft of the torsion spring seat 401. The dial wheel 403 rotates to intermittently actuate the vibration wheel 402. When the vibration wheel 402 returns to its original position, it strikes the first vibration seat 404. A bevel gear 103 is rotatably installed inside the fermentation box 1, and the bottom of the bevel gear 103 is fixedly connected to the arch-breaking main arm 3. Multiple bevel gears 104 that mesh with the bevel gear 103 are rotatably installed on the inner wall of the fermentation box 1. The shaft of the bevel gear 104 is fixedly connected to the shaft of the dial wheel 403. An inner protective cover 102 and an outer protective cover 105 are fixedly installed inside and outside the fermentation box 1, respectively. When the main arm 3 of the arch-breaking mechanism revolves within the fermentation chamber 1, it drives the bevel gear disc 103 to rotate. The bevel gear disc 103 transmits the rotational motion synchronously to all the dial wheels 403 through multiple bevel gears 104 meshing with it. During rotation, each dial wheel 403 intermittently actuates the protrusion on the corresponding vibrating wheel 402, causing the vibrating wheel 402 to deflect against the torque in the torsion spring seat 401. After the protrusion of the dial wheel 403 passes the protrusion, the vibrating wheel 402 quickly returns to its original position under the action of the torsion spring, and its striking head violently strikes the triangular first vibrating seat 404, thereby transmitting high-frequency, localized striking vibrations to the wall of the fermentation chamber 1. The inner protective cover 102 and the outer protective cover 105 are used to protect the internal transmission components and the external vibrating components, respectively, to prevent materials from entering and affecting the operation. The vibrating wheel 402 has an integrally formed protrusion and a striking head that contact the dial wheel 403. The length of the protrusion is less than the centrifugal length of the striking head. The first vibrating seat 404 is triangular. The protrusion is shorter, which makes the dial wheel 403 have a small stroke on the vibrating wheel 402, while the striking head has a large rotation angle. This leverage principle helps to achieve fast and high-frequency triggering. The triangular first vibrating seat 404 has a sloping structure that helps to decompose and transmit the striking force to the box wall more effectively. refer to Figure 9 The second vibration component 5 includes a bearing 501 and a guide plate 502. The bearing 501 is fixedly installed on the top of the arch-breaking seat 2. A turntable is rotatably installed on the bearing 501. The shaft of the turntable is fixedly connected to the shaft of the drive gear 204. An impact head 503 is longitudinally slidably installed on the turntable and is eccentrically set with the impact head 503. A fourth spring 504 is fixedly connected between the bottom of the impact head 503 and the turntable. The guide plate 502 is fixedly installed on the fermentation box 1. The impact head 503 is tightly attached to the guide plate 502 under the elastic force of the fourth spring 504. The turntable rotates coaxially with the drive gear 204 at a low speed. The impact head 503 mounted on the turntable is under the preload of the fourth spring 504, and the roller or slider at its bottom is always pressed tightly against the surface of the fixed guide plate 502. When the turntable drives the impact head 503 to revolve, the vertical position of the impact head 503 is determined by the contour of the guide plate 502 it passes through. refer to Figure 10 The bottom of the guide plate 502 is provided with a boss and an arc-shaped groove, both of which are located on the orbital trajectory of the impact head 503. The starting surfaces of the boss of the guide plate 502 are a slope and a vertical section, respectively. When the impact head 503 runs along the planar part of the guide plate 502, its position remains stable. When it runs to the starting slope of the boss, the impact head 503 is gradually raised, compressing the fourth spring 504 to accumulate energy. When the impact head 503 reaches the top of the boss, it suddenly falls into the vertical section at its end and directly enters the arc-shaped groove. Under the strong release of the fourth spring 504, the impact head 503 moves downward at high speed and hits the arch-breaking seat 2 or related structure at the bottom of the fermentation box 1, generating a strong low-frequency impact vibration. This process occurs periodically with the rotation of the turntable, forming a low-frequency heavy impact on the bottom structure of the box.

[0030] Working principle: The core arch-breaking function of the device is achieved by the arch-breaking main arm 3, which rotates close to the inner wall of the cone of the fermentation box 1. The arch-breaking main arm 3 revolves around the axis of the unloading channel through the drive mechanism in the arch-breaking seat 2. Because it is zigzag-shaped and its inclination is consistent with the cone of the box, its orbital trajectory is always close to the inner wall area, so it can directly act on the arch base formed by the material and the inner wall of the box. This is the basis of the arch-breaking of this patent.

[0031] Specifically, when the main boom 3 rotates, the bottom of the cone 304 intermittently rolls over the protruding teeth of the toothed ring 101. When passing the teeth, the cone 304 is pushed upward, compressing the second spring 305. When it falls into the recess between the teeth, the cone 304 returns to its original position under the action of the second spring 305. The downward movement of the cone 304 will push the insert rod 301 in contact with it to move into the main boom 3, compressing the first spring 303. When the insert rod 301 moves inward, its conical part disengages from the groove of the cone spike rod 306, and the cone spike rod 306 is then... Under the elastic force of the spring 307, it quickly pops out horizontally from inside the arch-breaking support arm 302, piercing the inner wall of the fermentation box 1 and directly chiseling the material arch base that is attached to it. Then, when the cone column 304 is pushed up by the protruding tooth again, the insertion rod 301 is reset under the action of the first spring 303, and its cone part is re-entered into the groove of the cone piercing rod 306, pulling the cone piercing rod 306 back, completing one extension and retraction cycle. The continuous rotation of the arch-breaking main arm 3 causes multiple cone piercing rods 306 to repeatedly pierce and retract in this way at high frequency, forming a continuous and powerful mechanical destruction on the circumferential inner wall arch base. Secondly, the principle of the graded vibration mechanism is as follows: the rotation of the main arm 3 for breaking the arch is transmitted to multiple meshing bevel gears 104 via the bevel gear disc 103 fixed to it, thereby driving all the dial wheels 403 to rotate synchronously. During rotation, the dial wheel 403 intermittently actuates the protrusion on the vibration wheel 402, causing it to deflect and store energy. When the protrusion of the dial wheel 403 passes, the vibration wheel 402 quickly returns to its original position under the torque of the torsion spring seat 401, and the striking head on it violently strikes the first vibration seat 404, thereby transmitting high-frequency, low-amplitude vibration to the side wall of the fermentation chamber 1 to loosen the adhesion between material particles, and at the same time driving the shaft of the drive gear 204 of the main arm 3 for breaking the arch. Simultaneously, the turntable rotates. The impact head 503, eccentrically mounted on the turntable, is kept in close contact with the surface of the fixed guide plate 502 under the action of the fourth spring 504. When the impact head 503 reaches the starting slope of the boss part of the guide plate 502, it is gradually lifted and the fourth spring 504 is compressed to store energy. After reaching the top of the boss, it suddenly falls into the vertical section or arc-shaped groove at the end. The energy stored in the fourth spring 504 is released instantly, driving the impact head 503 to move downward at high speed and heavily impact the arch-breaking seat 2 or related structure at the bottom of the fermentation box 1, generating a strong low-frequency, high-amplitude impact vibration, which is used to crack the material arch structure with strong integrity.
