The branches and leaves of trees in the garden produce a lot of organic waste, so they need to be processed in order to reduce garbage and thus reduce environmental pollution.

[0003] Organic waste microbial treatment is a technology that uses microbial enzymes to biodegrade organic waste. Microbial enzymes can decompose various organic substances in organic waste and convert them into inorganic substances, so that they can be used and reduce environmental pollution.

[0004] Referring to the Chinese patent document with authorization announcement number CN221158051U, a device for microbial enzymatic hydrolysis of garden waste is disclosed, which includes a decomposition tank body, a stirring and oxygenating device for stirring and oxygenating the garden waste in the tank body is arranged inside the decomposition tank body, a sealing cover is arranged on the top of the decomposition tank body, and a driving assembly is arranged on the top of the sealing cover. The garden waste is treated by delivering oxygen during the stirring and flipping process of the garden waste.

[0005] With regard to the above-mentioned related technologies, in the process of stirring and turning the garden waste, as the garden waste continues to enter, the stirring and oxygenating equipment finds it difficult to turn and stir the upper layer of the garden waste, resulting in the upper layer of the garden waste being unable to replenish oxygen in time, affecting the growth and metabolism of microorganisms, and not conducive to improving the treatment efficiency. Summary of the invention

[0006] In view of this, the present invention provides an organic waste biological treatment device, aiming to solve the problem of limited stirring range of garden waste in the prior art.

[0007] In order to solve the above technical problems, the present invention provides an organic waste biological treatment device, comprising a treatment box, a crushing mechanism for crushing tree branches and leaves is provided on the side wall of the treatment box, a stirring mechanism for turning and stirring the tree branches and leaves and an oxygenation mechanism for introducing air into the treatment box are provided in the treatment box;

[0008] The stirring mechanism comprises a first rotating source, a rotating rod and a stirring rod, wherein the first rotating source is mounted on the left side wall of the processing box, the rotating rod is connected to the end of the driving shaft of the first rotating source and extends in the left-right direction, and the stirring rod is fixedly connected to the side wall of the rotating rod and is provided with a plurality of stirring rods;

[0009] The processing box is also provided with a control mechanism for driving the stirring mechanism to move in the up and down directions, the control mechanism includes a second rotation source, a crankshaft, a connecting plate, a slider and a slide groove, the second rotation source is installed on the left side wall of the processing box, the crankshaft is connected to the end of the driving shaft of the second rotation source and extends in the left and right directions, the connecting plate extends in the up and down directions, the bent part of the crankshaft passes through the upper part of the connecting plate, the rotating rod passes through the lower part of the connecting plate, the slider is sleeved on the outer side wall of the rotating rod, and the slide groove is opened on the left side wall of the processing box and is for the slider to slide.

[0010] By adopting the above technical scheme, when it is necessary to process organic waste such as tree branches and leaves, the tree branches and leaves are first crushed by the crushing mechanism and then passed into the processing box, and then the first rotation source is started to drive the rotating rod to rotate. As the rotating rod rotates, the rotating rod drives multiple stirring rods to stir the debris such as tree branches and leaves. Then the second rotation source is started to drive the crankshaft to rotate, and the rotation of the crankshaft drives the connecting plate to move. Under the restriction of the slider and the slide groove, the connecting plate can drive the rotating rod to move upward. As the crankshaft continues to rotate, the rotating rod can be moved in the up and down directions, thereby expanding the stirring range and reducing the stirring blind area. While making each area of ​​the tree branches and leaves loose, it is beneficial to improve the uniformity of oxygen dispersion, thereby increasing the activity of microorganisms and improving the reaction effect.

[0011] During the process of stirring and flipping the tree branches and leaves, the stirring rod can move in the up and down directions, thereby expanding the stirring range and loosening the tree branches and leaves in the processing box, which is beneficial to the replenishment of oxygen and improves the reaction effect. At the same time, the crankshaft and the connecting plate can also stir and flip the tree branches and leaves when moving, thereby improving the reaction efficiency.

[0012] Optionally, the rotating rod can introduce air into the processing box through an oxygenation mechanism when moving up and down. The oxygenation mechanism includes a piston column, a piston cylinder, an air inlet pipe, an air outlet pipe, a first one-way valve and a second one-way valve. The upper surface of the piston column is fixedly connected to the side wall of the rotating rod, the piston cylinder is installed on the inner bottom wall of the processing box, and the piston column is slidably assembled inside the piston cylinder in the up and down directions. The air inlet pipe passes through the processing box and is connected to the interior of the piston cylinder. The first one-way valve is arranged on the air inlet pipe and allows air to enter only from the air inlet pipe. The air outlet pipe is arranged inside the processing box and is connected to the interior of the piston cylinder. The second one-way valve is arranged on the air outlet pipe and allows air to enter the processing box only from the air outlet pipe.

[0013] By adopting the above technical solution, when oxygen needs to be supplied to the treatment box, the rotating rod can drive the piston column to move in the up and down directions when it moves in the up and down directions. The piston column moves upward to draw external air through the air inlet pipe, and the piston column moves downward to introduce air into the treatment box through the air outlet pipe. The air rises from the bottom to the top, which is beneficial to the uniformity of oxygen supply to the branches and leaves of trees and improves the activity of microorganisms to facilitate their reaction.

[0014] The up and down movement of the rotating rod can realize oxygenation of the tree branches and leaves in the treatment box, and cooperate with the flipping and stirring process to evenly oxygenate the tree branches and leaves inside the treatment box to facilitate their reaction. At the same time, the incoming air enters from the bottom of the treatment box and oxygenates the tree branches and leaves from bottom to top, which is beneficial to the diffusion of air and improves the activity of microorganisms to facilitate the treatment of tree branches and leaves.

[0015] Optionally, the crushing mechanism includes a feed shell, a third rotation source, two mutually meshing crushing knives, a first gear and a second gear, the feed shell is arranged on the front side wall of the processing box, the third rotation source is installed on the side wall of the feed shell, the central axis of one of the crushing knives is connected to the end of the driving shaft of the third rotation source, and the first gear and the second gear are respectively mounted on the central axis of each crushing knife and mesh with each other.

[0016] By adopting the above technical solution, when raw materials such as tree branches and leaves need to be crushed, the third rotation source is first started. The third rotation source can drive the crushing knife to rotate. Through the engagement of the first gear and the second gear, the two crushing knives can rotate in opposite directions. When tree branches and leaves are placed on the two crushing knives, they can be crushed so that they can react better.

[0017] Optionally, a water supply pipe extending in the left and right directions is provided in the processing box body. The water supply pipe passes through the connecting plate and is located below the crankshaft. The right end of the water supply pipe extends out of the side wall of the processing box body and is connected to the water supply pipe. The connection between the water supply pipe and the water supply pipe is set as a hose.

[0018] By adopting the above technical scheme, when it is necessary to replenish water for the tree branches and leaves in the treatment box, when there is less water in the tree branches and leaves, it is necessary to replenish water to facilitate the reaction of the tree branches and leaves. Water is supplied to the water inlet pipe, and the water flows into the water replenishment pipe and sprays water mist on the tree branches and leaves through the nozzle. In the process of the crankshaft driving the stirring rod to move up and down to flip and stir the tree branches and leaves, the water replenishment pipe can move with the connecting plate, and the position of the water replenishment pipe can be changed to improve the uniformity of water replenishment for the tree branches and leaves. The tree branches and leaves are replenished with water during the flipping and stirring process, which is beneficial to the penetration of water, improves the uniformity of water replenishment, and improves the activity and metabolism of microorganisms, so as to facilitate the treatment of tree branches and leaves.

[0019] Optionally, a transverse plate extending in the front-to-rear direction is provided in the processing box, and the transverse plate is located above the crankshaft, a connecting rod is fixedly connected to the upper surface of the transverse plate, and a baffle for shielding the top of the processing box is fixedly connected to the top of the connecting rod.

[0020] By adopting the above technical solution, when it is necessary to discharge the heat and carbon dioxide in the processing box, the crankshaft will abut against the cross plate during rotation, and then the crankshaft will push the cross plate upward. During the upward movement of the cross plate, the baffle plate will move up through the connecting rod. As the baffle plate moves upward, the inside of the processing box can be connected with the outside world, so that the heat and carbon dioxide in the processing box can be discharged, so as to facilitate the reaction inside the processing box.

[0021] Optionally, a tension spring is sleeved on the connecting rod to reset the baffle.

[0022] By adopting the above technical solution, the setting of the tension spring can cooperate with the gravity of the baffle itself, so that when the crankshaft and the cross plate are released from abutment, the baffle moves downward and closes the processing box.

[0023] Optionally, a support rod is fixedly connected to the lower surface of the baffle, and a perforated plate slidably assembled in the processing box is fixedly connected to the bottom end of the support rod.

[0024] By adopting the above technical scheme, when tree branches and leaves carry a large amount of moisture, it will affect their reaction. The setting of the orifice plate can make the moisture carried by the tree branches and leaves leak through the orifice plate, and the orifice plate can move up and down with the horizontal plate, so that the excess moisture in the tree branches and leaves can be discharged in time, thereby avoiding excessive humidity in the treatment box to a certain extent, so as to facilitate the reaction, and the air introduced enters the space below the filter plate. In the process of the orifice plate moving downward, the air can be evenly dispersed into the tree branches and leaves through the orifice plate.

[0025] Optionally, a discharge port is provided at the lower portion of the processing box body, and a water outlet pipe is connected to the lower portion of the processing box body.

[0026] By adopting the above technical solution, the water outlet pipe can be discharged from the filter plate, and after the stirring rod is moved upward, the processed tree branches and leaves are removed through the discharge port for easy collection.

[0027] Optionally, partitions for shielding the slide groove are respectively provided on the left and right sides of the rotating rod.

[0028] By adopting the above technical solution, the partition can shield the chute, thereby reducing the probability of leakage of tree branches and leaves to a certain extent.

[0030] 1. When the stirring rod is stirring and turning the tree branches and leaves, the stirring rod can move in the up and down directions, thereby expanding the stirring range and making the tree branches and leaves in the treatment box loose, which is beneficial to the supplement of oxygen and improves the reaction effect. At the same time, the crankshaft and the connecting plate can also stir and turn the tree branches and leaves when moving, thereby improving the reaction efficiency.

[0031] 2. The up and down movement of the rotating rod can realize oxygenation of the tree branches and leaves in the treatment box, and cooperate with the flipping and stirring process to evenly oxygenate the tree branches and leaves inside the treatment box to facilitate their reaction.

[0051] The implementation principle of an organic waste biological treatment device according to an embodiment of the present invention is as follows:

[0052] The third rotation source 22 is started to drive the crushing blade 23 to rotate, and the two crushing blades 23 are rotated through the first gear 24 and the second gear 25, and then tree branches and leaves are put into the feed shell 21. After being crushed by the crushing blade 23, the tree branches and leaves enter the processing box 1.

[0053] Start the first rotation source 31 to drive the rotating rod 32 to rotate. As the rotating rod 32 rotates, the rotating rod 32 drives the stirring rod 33 to rotate and stir the tree branches and leaves. Then start the second rotation source 51 to drive the crankshaft 52 to rotate. The rotation of the crankshaft 52 can drive the connecting plate 53 to move, and then the connecting plate 53 drives the rotating rod 32 to move. Under the restriction of the slide groove 55, the rotating rod 32 moves in the up and down directions, so that the tree branches and leaves in the processing box 1 can be fully stirred to reduce the stirring blind area.

[0054] When the rotating rod 32 moves upward, it drives the piston column 41 to move upward. When the piston column 41 moves upward, it draws in outside air through the air inlet pipe 43. When the rotating rod 32 moves downward, it drives the piston column 41 to move downward. When the piston column 41 moves downward, it passes air into the processing box 1 through the air outlet pipe 44, thereby oxygenating the tree branches and leaves in the processing box 1. When it is necessary to replenish water in the processing box 1, water is introduced into the water supply pipe 61, and the water flows into the water replenishment pipe 6 and is sprayed through the spray head. The water replenishment pipe 6 will move with the connecting plate 53, so that the spraying is more uniform. When the tree branches and leaves carry a large amount of water, the water flows into the bottom of the processing box 1 through the orifice plate 75 and is discharged through the water outlet pipe 9.

[0055] The protruding portion of the crankshaft 52 can abut against the cross plate 7 and push the cross plate 7 to move upward when it rotates. When the cross plate 7 moves upward, the baffle 72 is driven to move upward through the support rod 74. The upward movement of the baffle 72 can open the processing box 1, so that the heat and carbon dioxide in the processing box 1 can be discharged. At the same time, when oxygen is supplemented in the processing box 1, the air enters under the orifice plate 75 and is evenly diffused through the orifice plate 75, which can evenly supplement oxygen for the branches and leaves of trees in the processing box 1, and the opening of the baffle 72 can also supplement oxygen for the branches and leaves of trees in the processing box 1.

[0056] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
