Description

Technical Field

[0001] This invention relates to the field of humic acid fertilizer preparation technology, specifically to a method and equipment for preparing humic acid fertilizer. Background Technology

[0002] Humic acid fertilizer is an organic fertilizer, mainly composed of natural high-molecular organic matter formed by the decomposition and transformation of organic matter such as animal and plant residues through microbial processes and geochemical processes. This fertilizer is mostly extracted from peat, lignite, and weathered coal, and contains rich organic nutrients, with multiple uses and effects.

[0003] Fermentation is required during the production of compost. Raw materials are poured into a composting box, and a humic acid bioconversion agent is added to the box to ferment and produce bio-humic acid, thereby improving soil fertility and promoting the absorption of nutrients by crops.

[0004] However, if the raw materials in the composting container cannot be turned and ventilated in time during the fermentation process, the raw materials cannot ferment evenly, the air inside the raw materials cannot be renewed, and the microorganisms in the raw materials cannot effectively decompose organic matter under anaerobic conditions, making it difficult to convert it into useful compounds such as humic acid, thereby reducing the fermentation efficiency.

[0005] This invention proposes a method and equipment for preparing humic acid fertilizer. During the fermentation process, the raw materials in the pile can be turned and ventilated in a timely manner. During the turning process, the turning plate can force air into the raw materials in the pile. The air will fill the gaps in the raw materials, reducing the density of the pile and greatly increasing the ventilation effect, ventilation area and ventilation area in the raw materials. The material can ferment evenly and improve the fermentation efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a method and equipment for preparing humic acid fertilizer, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a humic acid fertilizer preparation device, comprising a base plate and a stockpile box for holding raw materials, a turning mechanism above the base plate, the turning mechanism comprising a cross seat, two electric telescopic rods fixedly connected to the bottom of the cross seat, an L-shaped plate fixedly connected to the output end of the electric telescopic rods, and rotating rods rotatably connected to the inner walls of the two L-shaped plates on opposite sides, the rear end of the front rotating rod being fixedly connected to a cylinder, the cylinder being able to rotate and move above the stockpile box, the rear side of the cylinder being provided with an opening. The outer side of the cylinder is fixedly connected to several first flipping plates. The first flipping plates have a groove on the side away from the cylinder. A second flipping plate is slidably connected in the groove. The outer side of the second flipping plate is fixedly connected to several equally spaced inclined connecting blocks. The side of the connecting block has two symmetrically arranged inclined parts. An L-shaped flipping block is fixedly connected to the outer side of the connecting block. The side of the second flipping plate away from the cylinder is fitted with several balls. When the cylinder moves to the right and rotates, the second flipping plate and the first flipping plate can rotate clockwise into the pile and rotate out to achieve pile turning.

[0008] The cylinder is equipped with a ventilation mechanism. During soil turning, the ventilation mechanism can force air into the bottom pile through the first turning plate. The ventilation mechanism includes a grid disk, which is rotatably installed on the inner side of the cylinder. The grid disk is rotatably sleeved on the outer side of a rear rotating rod. Multiple impellers are fixedly connected to the outer side of the rear rotating rod. A cavity is opened on the second turning plate. Multiple round tubes are connected to and fixed on the outer side of the cylinder. The ends of the round tubes extend into the corresponding cavities. The second turning plate is slidably sleeved on the outer side of the corresponding round tubes.

[0009] More preferably, the inner wall of the cavity away from the corresponding connecting block has a plurality of first circular holes at equal intervals, and the inner wall of the groove away from the corresponding connecting block has a plurality of second circular holes at equal intervals, wherein the inner diameter of the first circular holes and the corresponding second circular holes are the same.

[0010] In a further preferred embodiment, a fixing plate is fixedly sleeved in the groove, and the fixing plate is fixedly sleeved on the outside of the circular tube. A spring that is movably sleeved on the outside of the circular tube is fixedly connected between the second tilting plate and the corresponding fixing plate. When the ball contacts the bottom inner wall of the stack box, the ball drives the second tilting plate to slide in the corresponding groove and compress the spring, so that the first circular hole coincides with the corresponding second circular hole, thereby achieving the purpose of ventilation.

[0011] In a further preferred embodiment, a gap exists between the fixed plate and the corresponding second tilting plate, which is filled with hydraulic oil. A gap is also left between the fixed plate and the corresponding groove near the inner wall of the cylinder. Two one-way valves with outlets at the top are embedded in the top of the fixed plate. The one-way valves can increase the flow area. When the second tilting plate moves upward, the hydraulic oil in the gap can be discharged into the gap through the one-way valves. Two through holes are opened at the bottom of the fixed plate. The resistance of the second tilting plate to resetting downward is determined by the diameter of the through holes. The through holes are used to realize the slow resetting of the second tilting plate.

[0012] More preferably, the front end of one of the rotating rods on the front side extends to the corresponding L-shaped plate and is fixedly connected to a large gear, and a first toothed plate is fixedly connected to the front side of the stack box, and the large gear meshes with the first toothed plate.

[0013] More preferably, the front end of one of the rotating rods on the rear side extends to the corresponding L-shaped plate and is fixedly connected to a small gear; a second toothed plate is fixedly connected to the rear side of the stack box; the small gear meshes with the second toothed plate; and two fixed rods are fixedly connected between the rear side of the grid disk and one of the L-shaped plates on the rear side.

[0014] More preferably, the top of the base plate is fixedly connected to four support plates, and the top of two corresponding support plates is fixedly connected to side plates. A screw is rotatably connected between the two side plates, and the cross seat is threadedly sleeved on the outside of the screw.

[0015] More preferably, two positioning rods are fixedly connected between the two side plates, and the cross seat is slidably sleeved on the outside of the two positioning rods. A motor is fixedly connected to the left side of one of the left side plates, and the output shaft end of the motor is fixedly connected to the left end of the screw.

[0016] More preferably, the top of the base plate is fixedly connected to four support legs, and the top of two corresponding support legs is fixedly connected to a support seat. The top of the support seat is provided with a sliding groove with an opening on the front side. The stack box is fixedly connected to two sliders, which are slidably connected to the corresponding sliding grooves. The sliders are threadedly connected to the corresponding support seats by bolts.

[0017] This invention also proposes a method for preparing humic acid fertilizer, comprising the following steps:

[0018] Step 1: Start the motor to rotate the cylinder and drive the first tipping plate to rotate and extend into the material pile for tipping. When the second tipping plate is perpendicular to the bottom inner wall of the pile box, the first circular hole and the second circular hole coincide.

[0019] Step 2: The impeller draws outside air into the cylinder, and the air is discharged into the raw material of the stockpile through the first circular hole and the corresponding second circular hole. The air will fill the gaps in the raw material of the stockpile, greatly increasing the ventilation effect of the raw material of the stockpile.

[0020] Step 3: As the connecting block and the L-shaped turning block move the stockpile material to the left, the stockpile material slides down along the inclined part set on the connecting block to achieve the purpose of uniform material drop;

[0021] Step 4: The forward start of the electric telescopic rod drives the large gear to move downward and mesh with the first toothed plate, changing the initial position of the large gear meshing with the first toothed plate. When the cylinder rotates and moves above the stack box, it achieves the effect of fully turning and ventilating the stack material in the stack box.

[0022] Step 5: Rotate the bolts in the opposite direction to separate them from the support bases, hold the stack box and move it forward to remove it from the top of the two support bases.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, the starting motor drives the horizontal seat to move via the rotation of the screw. The horizontal seat moves via the movement of the electric telescopic rod, which in turn moves the L-shaped plate. The L-shaped plate drives the large gear to mesh and rotate at the top of the first toothed plate via the rotation rod. The rotation rod drives the four first tipping plates to rotate via the rotation of the cylinder. The rotation of the first tipping plates drives the second tipping plates to rotate downward and extend into the material pile for tipping. The ball bearings contact the bottom inner wall of the pile box and generate extrusion force. The ball bearings drive the second tipping plates to slide in the groove and compress the spring. The second tipping plates move upward and discharge hydraulic oil through the one-way valve into the gap above the fixed plate. When the second tipping plate is perpendicular to the bottom inner wall of the pile box, the first circular hole and the second circular hole coincide.

[0025] 2. The movement of the L-shaped plate on the rear side drives the rotating rod on the rear side to rotate. The rotation of the rotating rod on the rear side drives the pinion to mesh and rotate on the top of the second gear plate. The pinion is fixedly connected to the impeller through the rotating rod. The impeller draws outside air into the cylinder, and the cylinder discharges the air into the cavity. The cavity discharges the air into the raw material pile through the first and second circular holes. The air will fill the gaps in the raw material pile. When the ball bearings separate from the bottom inner wall of the pile box, the elastic force of the spring drives the second turning plate to slowly return to its original position. This allows more air to be injected into the gaps in the raw material pile through the second circular hole, increasing the ventilation effect, ventilation area, and ventilation area in the raw material pile. The material can ferment evenly, improving the fermentation efficiency. During the process of the raw material pile turning to the left, the raw material pile slides down along the inclined part set on the connecting block. The first turning plate drives the second turning plate to continue rotating, achieving one cycle.

[0026] 3. This invention can also evenly turn the material. Reverse activation of the electric telescopic rod drives the large gear to separate from the first toothed plate. The starting motor changes the initial horizontal position of the cross seat via the screw. Forward activation of the electric telescopic rod drives the large gear downward to mesh with the first toothed plate, changing the initial meshing position of the large gear and the first toothed plate. When the cylinder rotates and moves above the stack box, it achieves the effect of fully turning and ventilating the raw materials inside the stack box. When the stack box needs to be removed, reverse rotation of the bolt separates it from the support seat. Holding the stack box, it moves forward and is removed from the top of the two support seats. This invention can timely turn and ventilate the raw materials during fermentation. During the turning process, the turning plate can force air into the raw materials. The air fills the gaps in the raw materials, reducing the density of the stack and greatly increasing the ventilation effect, ventilation area, and ventilation area within the raw materials. The material can ferment evenly, improving fermentation efficiency. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] For examples, please refer to Figure 1-12This invention provides a technical solution: a humic acid fertilizer preparation device, comprising a base plate 1 and a stockpile box 5 for holding raw materials. A turning mechanism is provided above the base plate 1. The turning mechanism includes a horizontal seat 104, with two electrically operated telescopic rods 105 fixedly connected to the bottom of the horizontal seat 104. An L-shaped plate 106 is fixedly connected to the output end of each of the electrically operated telescopic rods 105. Rotating rods 107 are rotatably connected to the inner walls of the two L-shaped plates 106 on opposite sides. A cylinder 108 is fixedly connected to the rear end of the front rotating rod 107. The cylinder 108 can rotate and move above the stockpile box 5. The rear side of the cylinder 108 is open, and the outer side of the cylinder 108 is fixedly connected to... There are several first turning plates 109. A groove 110 is provided on the side of the first turning plate 109 away from the cylinder 108. A second turning plate 111 is slidably connected in the groove 110. A plurality of equally spaced inclined connecting blocks 112 are fixedly connected to the outside of the second turning plate 111. Two symmetrically arranged inclined parts 119 are provided on the side of the connecting block 112. An L-shaped turning block 113 is fixedly connected to the outside of the connecting block 112. A plurality of balls 114 are embedded on the side of the second turning plate 111 away from the cylinder 108. When the cylinder 108 moves to the right and rotates, the second turning plate 111 and the first turning plate 109 can rotate clockwise into the pile and rotate out to achieve turning.

[0045] The cylinder 108 is equipped with a ventilation mechanism. During soil turning, the ventilation mechanism can force air into the bottom pile through the first turning plate 109. The ventilation mechanism includes a grid disk 2, which is rotatably installed on the inner side of the cylinder 108. The grid disk 2 is rotatably sleeved on the outer side of a rear rotating rod 107. Multiple impellers 201 are fixedly connected to the outer side of the rear rotating rod 107. A cavity 204 is opened on the second turning plate 111. Multiple round tubes 205 are connected and fixed on the outer side of the cylinder 108. The ends of the round tubes 205 extend into the corresponding cavities 204. The second turning plate 111 is slidably sleeved on the outer side of the corresponding round tubes 205.

[0046] In this embodiment, specifically: a plurality of first circular holes 206 are equally spaced on the inner wall of the cavity 204 away from the corresponding connecting block 112, and a plurality of second circular holes 207 are equally spaced on the inner wall of the groove 110 away from the corresponding connecting block 112, wherein the inner diameter of the first circular holes 206 and the corresponding second circular holes 207 are the same.

[0047] This invention enables timely turning and ventilation of the raw materials during fermentation. The turning plate can force air into the raw materials during the turning process. The air fills the gaps between the raw materials, reducing the density of the pile and greatly increasing the ventilation effect, ventilation area and ventilation area in the raw materials. The material can ferment evenly, improving the fermentation efficiency.

[0048] The raw materials are poured into the fermentation box 5 for fermentation. When it is necessary to turn and ventilate the raw materials in the fermentation box 5, the motor 118 is started. The motor 118 drives the screw 103 to rotate, which in turn moves the horizontal seat 104. The horizontal seat 104 slides on the outside of the two positioning rods 117. The horizontal seat 104 drives the two electric telescopic rods 105 to move, which in turn moves the corresponding L-shaped plate 106. The movement of the front L-shaped plate 106 drives the front rotating rod 107 to rotate, which in turn drives the large gear 115 to mesh and rotate at the top of the first toothed plate 116. The rotation of the front rotating rod 107 drives the cylinder 108 to rotate, which in turn drives the four first turning plates 109 to rotate. The rotation of the first turning plates 109 drives the second turning plates 111 to rotate, which in turn drives multiple connecting blocks 112 to rotate. Block 112 drives the corresponding L-shaped turning block 113 to rotate. When the second turning plate 111 on the right rotates downward and extends into the raw material of the stack, the first turning plate 109, the second turning plate 111, the connecting block 112 and the L-shaped turning block 113 drive the raw material of the stack to turn to the left. The second turning plate 111 drives the ball 114 to gradually rotate downward. The ball 114 contacts the bottom inner wall of the stack box 5 and generates a squeezing force. Under the action of the squeezing force, the ball 114 drives the second turning plate 111 to slide in the corresponding groove 110 and compress the spring 209. The second turning plate 111 moves upward and can discharge the hydraulic oil in the gap between the fixed plate 208 and the second turning plate 111 through the one-way valve 210 into the gap above the fixed plate 208. When the second turning plate 111 is perpendicular to the bottom inner wall of the stack box 5, the first circular hole 206 coincides with the corresponding second circular hole 207.

[0049] In this embodiment, specifically: a fixing plate 208 is fixedly sleeved in the groove 110, and the fixing plate 208 is fixedly sleeved on the outside of the round tube 205. A spring 209, which is movably sleeved on the outside of the round tube 205, is fixedly connected between the second tilting plate 111 and the corresponding fixing plate 208. When the ball 114 contacts the bottom inner wall of the stack box 5, the ball 114 drives the second tilting plate 111 to slide in the corresponding groove 110 and compress the spring 209, so that the first circular hole 206 coincides with the corresponding second circular hole 207, thereby achieving the purpose of ventilation.

[0050] In this embodiment, specifically: there is a gap between the fixed plate 208 and the corresponding second tilting plate 111, which is filled with hydraulic oil. There is also a gap between the fixed plate 208 and the corresponding groove 110 near the inner wall of the cylinder 108. Two one-way valves 210 with outlets at the top are embedded in the top of the fixed plate 208. The one-way valves 210 can increase the flow area. When the second tilting plate 111 moves upward, the hydraulic oil in the gap can be discharged into the gap through the one-way valves 210. Two through holes 211 are opened at the bottom of the fixed plate 208. The resistance of the second tilting plate 111 to reset downward is determined by the diameter of the through holes 211. The through holes 211 are used to realize the slow reset of the second tilting plate 111.

[0051] Simultaneously, the movement of the L-shaped plate 106 on the rear side drives the rotation rod 107 on the rear side to rotate. The rotation of the rotation rod 107 on the rear side drives the small gear 202 to mesh and rotate at the top of the second gear plate 203. The radius of the large gear 115 is many times the radius of the small gear 202. The small gear 202 is fixedly connected to the impeller 201 through the rotation rod 107. That is, when the large gear 115 rotates one revolution, the impeller 201 obtains a speed many times faster. The impeller 201 draws outside air into the cylinder 108. The cylinder 108 discharges the air into the circular tube 205. The circular tube 205 discharges the air into the corresponding cavity 204. The cavity 204 discharges the air into the raw material of the stockpile through the first circular hole 206 and the corresponding second circular hole 207. The air will fill the gaps in the raw material of the stockpile, greatly increasing the efficiency of the stockpile. Regarding the ventilation effect of the raw materials, when the ball bearing 114 separates from the bottom inner wall of the stack box 5, the spring 209, which is under compression, returns to its original position. The elastic force of the spring 209 drives the second tilting plate 111 to move downward. The magnitude of the downward resistance of the second tilting plate 111 is determined by the diameter of the through hole 211. The through hole 211 reduces the diameter of the hydraulic oil return flow, which is used to slowly reset the material, thereby slowing down the downward movement speed of the second tilting plate 111. This increases the communication time between the first circular hole 206 and the corresponding second circular hole 207, allowing more air to be injected into the gaps of the raw materials in the stack through the second circular hole 207. This greatly increases the ventilation effect, ventilation area, and ventilation area in the raw materials in the stack, enabling the material to ferment evenly and improving the fermentation efficiency.

[0052] In this embodiment, specifically: the front end of a rotating rod 107 extends to the outside of the corresponding L-shaped plate 106 and is fixedly connected to a large gear 115; a first toothed plate 116 is fixedly connected to the front side of the stack box 5; and the large gear 115 meshes with the first toothed plate 116.

[0053] In this embodiment, specifically: the front end of a rotating rod 107 on the rear side extends to the corresponding L-shaped plate 106 and is fixedly connected to a pinion 202; a second toothed plate 203 is fixedly connected to the rear side of the stack box 5; the pinion 202 meshes with the second toothed plate 203; and two fixed rods 212 are fixedly connected between the rear side of the grid disk 2 and the L-shaped plate 106 on the rear side.

[0054] As the connecting block 112 and the L-shaped turning block 113 drive the stockpile material to turn to the left, the stockpile material slides down along the inclined part 119 set on the connecting block 112 to achieve the purpose of uniform material falling. The first turning plate 109 drives the second turning plate 111 to continue to rotate, so that during the rotation of the lower first turning plate 109, the first circular hole 206 on it and the corresponding second circular hole 207 on the second turning plate 111 are misaligned, so that the first turning plate 109 is in a blocked state, thereby achieving a cycle.

[0055] While a transmission mechanism can only achieve fixed-point material turning, this invention can also turn materials evenly. Reverse-starting the electric telescopic rod 105 drives the corresponding L-shaped plate 106 upwards. The movement of the L-shaped plate 106 drives the rotating rod 107 upwards. The rotation of the front rotating rod 107 causes the large gear 115 to separate from the first toothed plate 116, and the rotation of the rear rotating rod 107 causes the small gear 202 to separate from the second toothed plate 203. At this time, the starting motor 118 changes the initial horizontal position of the cross seat 104 via the screw 103. Immediately afterwards, forward-starting the electric telescopic rod 105 drives the large gear 115 downwards via the L-shaped plate 106 to mesh with the first toothed plate 116, thus changing the initial meshing position of the large gear 115 and the first toothed plate 116. When the cylinder 108 rotates and moves above the stack box 5, it changes the rotation and turning positions of the first turning plate 109 and the second turning plate 111, achieving the effect of fully turning and ventilating the raw materials in the stack box 5.

[0056] In this embodiment, specifically: four support plates 101 are fixedly connected to the top of the base plate 1, and side plates 102 are fixedly connected to the top of two corresponding support plates 101. A screw 103 is rotatably connected between the two side plates 102, and a cross seat 104 is threaded onto the outside of the screw 103.

[0057] In this embodiment, specifically: two positioning rods 117 are fixedly connected between the two side plates 102, the cross seat 104 is slidably sleeved on the outside of the two positioning rods 117, and a motor 118 is fixedly connected to the left side of one of the left side plates 102, and the output shaft end of the motor 118 is fixedly connected to the left end of the screw 103.

[0058] In this embodiment, specifically: four support legs 3 are fixedly connected to the top of the base plate 1, and support seats 4 are fixedly connected to the top of the corresponding two support legs 3. The top of the support seat 4 is provided with a sliding groove with an opening on the front side. Two sliders 6 are fixedly connected to the stack box 5. The sliders 6 are slidably connected to the corresponding sliding grooves. The sliders 6 are threadedly connected to the corresponding support seats 4 by bolts 7.

[0059] When the fermentation of the raw materials in the stack box 5 is completed, and the stack box 5 needs to be removed, the electric telescopic rod 105 is started in the reverse direction to drive the cylinder 108 to move upward. The bolt 7 is rotated in the reverse direction to separate from the support seat 4. The stack box 5 is held and moved forward. The stack box 5 drives the slider 6 to move out of the slide groove. At this time, the stack box 5 can be removed from the top of the two support seats 4.

[0060] This invention also proposes a method for preparing humic acid fertilizer, comprising the following steps:

[0061] Step 1: Start the motor 118 to rotate the cylinder 108 and drive the first tipping plate 109 to rotate and extend into the raw material pile for tipping. When the second tipping plate 111 is perpendicular to the bottom inner wall of the pile box 5, the first circular hole 206 and the second circular hole 207 coincide.

[0062] Step 2: Impeller 201 draws outside air into cylinder 108. The air is discharged into the raw material of the stockpile through the first circular hole 206 and the corresponding second circular hole 207. The air will fill the gaps in the raw material of the stockpile, greatly increasing the ventilation effect of the raw material of the stockpile.

[0063] Step 3: As the connecting block 112 and the L-shaped turning block 113 move the stockpile material to the left, the stockpile material slides down along the inclined part 119 set on the connecting block 112 to achieve the purpose of uniform material dropping;

[0064] Step 4: The forward start of the electric telescopic rod 105 drives the large gear 115 to move downward and mesh with the first toothed plate 116, changing the initial position of the large gear 115 meshing with the first toothed plate 116. When the cylinder 108 rotates and moves above the stack box 5, it achieves the effect of fully turning and ventilating the stack material in the stack box 5.

[0065] Step 5: Rotate the bolt 7 in the opposite direction to separate it from the support base 4, hold the stack box 5 and move it forward to remove it from the top of the two support bases 4.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
