Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer fermentation, in particular to a poultry and livestock manure organic fertilizer fermentation tank. Background Art

[0002] In agricultural production, livestock manure is an important organic resource. Traditionally, it is processed by open-air pile fermentation. This primitive method is time-consuming and usually takes several months or even more than half a year to complete composting, which seriously restricts the efficiency of organic fertilizer production. Moreover, since it is completely dependent on natural conditions, it is greatly affected by weather factors. Rainfall will wash away the fermentation pile and cause nutrient loss, the pile will be too wet and affect the activity of microorganisms or even interrupt fermentation, and high temperature will cause water to evaporate quickly and the fermentation pile to dry, resulting in insufficient fermentation and reduced quality of organic fertilizer. In addition, in order to promote the fermentation process, it is often necessary to spray liquids such as microbial agent diluent, moisture regulating liquid, acid-base regulating liquid, etc.

[0003] In the prior art, such as the patent number CN215906112U, an organic fertilizer fermentation tank includes a tank body, an anti-odor cover, an adjustment component and a stirring component. The top of the tank body is provided with an opening, one end of the anti-odor cover is hingedly arranged on one side of the top of the tank body and is located above the opening, the adjustment component is arranged on the top of the tank body and is located between the anti-odor cover and the opening, and the stirring component is arranged on the adjustment component and is located in the tank body. This scheme drives the stirring rod to rotate by rotating gear one, gear five and gear six to stir the raw materials in the shovel box, and drives the shovel box to rotate by rotating gear two, gear three, internal gear and rotating drum. When the shovel box drives the organic fertilizer to run to the top, it is fully in contact with the air through the stirring of the stirring rod. Multiple rotating shovels turn the organic fertilizer comprehensively to avoid the accumulation of organic fertilizer. The organic fertilizer can be fully fermented, which improves the efficiency of organic fertilizer fermentation. The utility model relates to the technical field of organic fertilizer, and specifically provides an organic fertilizer fermentation tank.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides two technical solutions:

[0032] Figure 1-Figure 7 The first embodiment is shown: a poultry and livestock manure organic fertilizer fermentation tank, including a tank body 1, the top of which is hingedly connected with a sealing cover 2, by opening the sealing cover 2, organic fertilizer can be conveniently added into the tank body 1, when the organic fertilizer in the tank body 1 is in the fermentation process, the sealing cover 2 is closed, which can effectively prevent external dust, debris, rainwater and various harmful microorganisms from entering the tank body 1. To prevent these impurities from mixing into the organic fertilizer, the purity of the organic fertilizer is ensured, and the cleanliness of the fermentation environment is maintained, the top of the sealing cover 2 is provided with an exhaust component 3, the inner wall of the tank body 1 is provided with a stirring component 4 for stirring the organic fertilizer in the tank body 1, and the outer wall of the tank body 1 is provided with a spraying component 5;

[0033] The exhaust assembly 3 includes an exhaust pipe 31, the exhaust pipe 31 is fixedly connected to the sealing cover 2, and a sealing plate 35 is provided at the top of the exhaust pipe 31;

[0034] The stirring assembly 4 includes two stirring rods 41, and a set of stirring plates 42 are fixedly mounted on the outer walls of the two stirring rods 41. The two sets of stirring plates 42 are staggered with each other to prevent the two sets of stirring plates 42 from colliding during rotation.

[0035] The spray assembly 5 includes two spray pipes 57, which are rotatably installed on the inner wall of the trough body 1. The outer walls of the two spray pipes 57 are fixedly sleeved with second gears 58, and the outer walls of the two second gears 58 are meshed with racks 55. When the racks 55 move, they can drive the second gears 58 to rotate, and the second gears 58 can then drive the spray pipes 57 to rotate. A connecting plate 54 is fixedly installed on the top of the two racks 55, and a connecting rod 53 is rotatably installed on the top of the connecting plate 54. A rotating circular plate 52 is rotatably installed on one end of the outer wall of the connecting rod 53. When the rotating circular plate 52 rotates, it will drive the connecting rod 53 to move. When the connecting rod 53 moves, it will drive the connecting plate 54 and the two racks 55 to move back and forth up and down.

[0036] One end of the outer wall of the two stirring rods 41 passes through the outer wall of the trough body 1, and two first gears 44 are fixedly installed on each of them. The two first gears 44 are meshed with each other. A motor 43 is fixedly installed on the outer wall of the trough body 1. The output end of the motor 43 passes through the inner wall of the trough body 1 and is fixedly connected to the other end of the outer wall of one of the two stirring rods 41. When the motor 43 drives one stirring rod 41 to rotate, it will drive the other stirring rod 41 to rotate in the opposite direction through the first gear 44.

[0037] A mounting frame 51 is fixedly mounted on the outer wall of the tank body 1, and a rotating shaft is rotatably mounted on the outer wall of the mounting frame 51. One end of the outer wall of the rotating shaft penetrates the outer wall of the mounting frame 51 and is fixedly connected to the rotating circular plate 52. When the rotating shaft rotates, it will drive the rotating circular plate 52 to rotate.

[0038] A driving wheel 45 is fixedly mounted on the outer wall of one of the two first gears 44, and a driven wheel 47 is fixedly mounted on the other end of the outer wall of the rotating shaft. Belts 46 are sleeved on the outer walls of the driving wheel 45 and the driven wheel 47. When the first gear 44 rotates, the driving wheel 45 is driven to rotate, and the driving wheel 45 drives the driven wheel 47 and the rotating shaft to rotate through the belt 46.

[0039] Figure 1-Figure 7 A second embodiment is shown, and its main difference from the first embodiment is that a group of nozzles are provided at the bottom ends of the two spray pipes 57, one end of the outer wall of the two spray pipes 57 passes through the outer wall of the trough body 1, and both are fixedly connected with a rotating joint 59. The rotating joint 59 is a prior art and can continuously provide liquid to the spray pipe 57 when the spray pipe 57 rotates.

[0040] The outer walls of the two racks 55 are slidably provided with limit sliders 56 for limiting the racks 55. The limit sliders 56 can make the racks 55 move only in the vertical direction. One end of the outer walls of the two limit sliders 56 is fixedly connected to the outer wall of the trough body 1.

[0041] A bracket 32 ​​is fixedly installed on the inner wall of the exhaust pipe 31, and a slide rod 33 slides through the top of the bracket 32. A spring 34 is sleeved on the outer wall of the slide rod 33, and the top of the slide rod 33 is fixedly connected to the sealing plate 35. Under normal conditions, the spring 34 is in a contracted state, which will make the sealing plate 35 fit tightly with the exhaust pipe 31. When the pressure in the tank body 1 is too high, the sealing plate 35 will be squeezed by the gas and move upward, so that the exhaust pipe 31 is opened, thereby relieving the pressure of the gas in the tank body 1.

[0042] A limit plate 36 is fixedly installed at the bottom end of the slide rod 33 , and the limit plate 36 can prevent the sealing plate 35 from moving too high. One end of the spring 34 is fixedly connected to the sealing plate 35 , and the other end of the spring 34 is fixedly connected to the top end of the bracket 32 ​​.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] During operation, when it is necessary to ferment the organic fertilizer, the sealing cover 2 is first opened, and then the organic fertilizer is poured into the interior of the tank body 1, and then the sealing cover 2 is closed, so that the organic fertilizer is fermented inside the tank body 1. At the same time, in order to increase the fermentation speed of the organic fertilizer inside the tank body 1, the motor 43 can be turned on, and its output end drives the stirring rod 41 fixedly connected thereto to rotate. Since the two first gears 44 are meshed with each other, the other stirring rod 41 also rotates accordingly. The stirring plates 42 staggered on the two stirring rods 41 stir the organic fertilizer in the tank body 1, so that the organic fertilizer is mixed more evenly, creating good conditions for fermentation, and then the two rotating joints 59 are connected to the external liquid supply device, so that the spray pipe 57 sprays liquid downward through the nozzle, and when the stirring assembly 4 stirs, a driving wheel 45 fixedly connected to the first gear 44 also rotates together, and the driven wheel 47 is driven to rotate through the belt 46, thereby rotating the rotating shaft, and the rotating shaft drives the rotating circular plate 52 to rotate. When the rotating circular plate 52 rotates, it drives the connecting rod 53 to move, and the connecting rod 53 pushes the connecting plate 54 to move up and down. The connecting plate 54 drives the rack 55 fixed thereto to slide back and forth up and down, and the rack 55 meshes with the second gear 58, so that the two spray pipes 57 swing in opposite directions within a certain angle. The spraying range is expanded, and the organic fertilizer at various positions in the tank body 1 can be effectively sprayed, thereby improving the spraying effect of the organic fertilizer. When too much biogas is generated inside the tank body 1, the internal pressure of the tank body 1 increases, and the gas pushes the sealing plate 35 to move upward, the sliding rod 33 slides on the bracket 32, and the spring 34 is stretched. At this time, the sealing plate 35 moves upward to open the exhaust pipe 31 and discharge the biogas. When the pressure in the tank body 1 is reduced, the biogas generated by the fermentation is discharged in time to avoid excessive pressure in the tank body 1, thereby ensuring the safe and stable progress of the fermentation process. At the same time, a biogas treatment device can be set at the opening of the exhaust pipe 31 to prevent biogas from polluting the air environment. When the pressure in the tank body 1 gradually decreases with the discharge of the gas, when the upward pressure of the internal gas is less than the elastic force of the spring 34, the spring 34 begins to recover and pushes the sealing plate 35 to move downward. The slide bar 33 also slides downward accordingly. When the sealing plate 35 is tightly fitted with the top of the exhaust pipe 31 again, the exhaust pipe 31 is closed, effectively preventing the outside air, dust, debris, etc. from entering the tank body 1, avoiding interference with the fermentation process of the organic fertilizer, and ensuring the relative stability and cleanliness of the fermentation environment.
