Description

Technical Field

[0001] This application relates to the technical field of composting substrate preparation, and more specifically, to a sawdust composting device for cultivating Lactobacillus pineae. Background Technology

[0002] Lactarius deliciosus is a fungus widely distributed in Asia, Europe and North America. It belongs to the Russula family and the Lactarius genus. It is an edible mushroom with rich nutritional and medicinal value. In the cultivation of Lactarius deliciosus, sawdust is the most important raw material. In the cultivation process, sawdust mainly serves as a carbon source, filler, water retainer and porosity adjuster. The sawdust needs to be decomposed before it can be used as a substrate for planting Lactarius deliciosus.

[0003] Currently, sawdust decomposition mainly employs the method of pre-wetting with water and natural fermentation in piles. However, the inventors realized that during sawdust decomposition, it is also necessary to add an appropriate amount of nitrogen source, such as nitrogen fertilizer and poultry manure, and adjust the carbon-nitrogen ratio to provide sufficient nutrition for the pine milk mushroom. This requires mixing the nitrogen source with the sawdust, wetting it, and then allowing it to decompose naturally. During the process, it is also necessary to turn the pile regularly to promote aerobic respiration of bacteria and accelerate the decomposition process. In most cases, the pile is turned manually using a lifting board, which is labor-intensive and makes it difficult to ensure that the pile is mixed evenly.

[0004] To address the aforementioned issues, we provide a sawdust decomposition device for cultivating Lactarius deliciosus. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides a sawdust decomposition device for cultivating Lactarius deliciosus.

[0006] The sawdust decomposition device for cultivating Lactarius deliciosus provided in this application adopts the following technical solution: A sawdust decomposition device for cultivating Lactarius deliciosus includes a cylindrical decomposition chamber and further includes: The rotating roller is rotatably installed at the center of the corrosion chamber to support the corrosion chamber, and a rotating frame is also fitted on the rotating roller inside the corrosion chamber. The mixing assembly, located at one end of the rotating frame, includes a rotating shaft and multiple turning rollers evenly distributed on the surface of the rotating shaft, for turning and mixing the stockpile of materials; The material pushing assembly includes a pusher plate that is slidably mounted on the other end of the rotating frame for pushing the material out of the stack and cleaning the inner wall of the decomposition chamber.

[0007] In some implementations, supports are installed at both the front and rear ends of the corrosion chamber, and a base plate is connected to the bottom of the supports; A drive motor is also installed on the base plate, and a belt assembly is set between the drive motor and the rotating roller to drive the rotating roller to rotate.

[0008] In some embodiments, arc-shaped racks are also installed on the inner walls at both ends of the corrosion chamber, and a gap is provided between the rotating frame and the front and rear end side walls of the corrosion chamber. The arc-shaped racks are placed in the gaps, and the outer end of the rotating shaft passes through the rotating frame and is equipped with a driven gear. The driven gear meshes with the arc-shaped racks.

[0009] In some embodiments, a groove is provided at one end of the rotating frame along the axial direction, and the push plate is slidably embedded in the groove, with the two sides of the push plate making sliding contact with the inner wall of the corrosion chamber.

[0010] In some embodiments, the inside of the rotating roller is hollow, and a bidirectional lead screw is installed at the center of the rotating roller. A shaft sleeve is threaded at the threaded ends of both ends of the bidirectional lead screw. A diagonal brace is hinged between the two shaft sleeves and the push plate. The two diagonal braces are arranged in a figure-eight shape. A crank handle is also installed at one end of the bidirectional lead screw.

[0011] In some embodiments, a through groove is also provided on the roller along the axial direction. The through groove is located in the middle of the roller, and both diagonal braces are inserted into the through groove.

[0012] In some embodiments, the arc surface of the corrosion chamber is provided with a chamber opening, a chamber door panel is hinged at the chamber opening, a rubber strip is provided around the outer edge of the chamber door panel, and a clamping plate is also installed on the outer side of the chamber door panel, with bolts for fixing it in place.

[0013] In some embodiments, an arc-shaped rail is also fitted on the arc surface of the corrosion chamber. The arc-shaped rail is located below the chamber opening. A slide block is slidably installed inside the arc-shaped rail. An arc-shaped strip is also installed between the slide block and the chamber door panel. A threaded knob is also provided on the slide block for fixing.

[0014] In some embodiments, the top of the arc-shaped strip is hinged to the outer side of the top of the door panel, and the center of the door panel and the arc-shaped strip are aligned with the center of the corrosion chamber.

[0015] In summary, in the technical solution of this application embodiment, an appropriate amount of mixed material is first added to the decomposition chamber. When the rotating roller drives the rotating frame to rotate, the mixing component and the pushing component on it can alternately contact the material at the bottom of the decomposition chamber. During the mixing stage, the pushing plate will move closer to the center of the rotating frame. At this time, the pushing plate will only contact the top of the material, which is convenient for flattening the material. The driven gear of the mixing component will mesh with the arc-shaped rack to drive the rotating shaft to rotate. When the turning roller on the rotating shaft rotates, it can turn the material, which is convenient for mixing the material evenly. The material can also be turned over periodically to promote the aerobic respiration of bacteria in the material. During the discharge stage, the pushing plate will slide to the outer end of the rotating frame until the pushing plate contacts the inner wall of the decomposition chamber. At this time, when the rotating frame drives the pushing plate to rotate, it can push the material at the bottom of the decomposition chamber toward the chamber opening, which is convenient for discharge. Moreover, the pushing plate can also clean the material adhering to the inner wall of the decomposition chamber, achieving a self-cleaning effect. In the technical solution of this application embodiment, the silo door panel is hinged and installed at the silo opening. An arc-shaped strip is also installed on the slide in the arc-shaped rail to support the silo door panel. When the silo door panel is open, the arc-shaped strip can also support the silo door panel, thereby acting as a guide plate to provide guidance and support for stacking materials and facilitate material loading and unloading.

Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features.

[0020] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0021] In related technologies, sawdust needs to be mixed with a nitrogen source to decompose in order to provide sufficient nutrition for the pine milk mushroom. However, in most cases, the method of manually turning over and mixing the pile is labor-intensive and makes it difficult to ensure that the pile is mixed evenly. To ensure thorough and uniform mixing of the stockpile, refer to Figures 1 to 3 As shown, the corrosion device of this application includes a corrosion chamber 1 arranged in a cylindrical shape. A rotating roller 2 is installed through the center of the corrosion chamber 1. A rotating frame 3 is also mounted on the rotating roller 2. There are two rotating frames 3. A mixing component 31 and a pushing component 32 are arranged between the two rotating frames 3. When working, the rotating roller 2 can rotate with the rotating frame 3, and the mixing component 31 and the pushing component 32 on the rotating frame 3 can alternately contact the stockpile. In this embodiment of the application, the mixing component 31 includes a rotating shaft 3101 and a plurality of turning rollers 3102 evenly distributed on the surface of the rotating shaft 3101. The ends of the turning rollers 3102 are arranged close to the inner wall of the corrosion chamber 1. When the rotating shaft 3101 rotates and comes into contact with the piled material, the turning rollers 3102 on it can turn the piled material, which facilitates mixing the piled material. In this embodiment, an arc-shaped rack 3103 is also installed on the inner walls of the front and rear ends of the corrosion chamber 1. A gap is also provided between the rotating frame 3 and the front and rear end side walls of the corrosion chamber 1. The arc-shaped rack 3103 is set in the gap. The outer end of the rotating shaft 3101 passes through the rotating frame 3 and is equipped with a driven gear 3104. The driven gear 3104 meshes with the arc-shaped rack 3103. The arc-shaped rack 3103 is located in the lower half of the entire arc. This means that when the driven gear 3104 rotates to the lower half of the corrosion chamber 1, the driven gear 3104 will mesh with the arc-shaped rack 3103. During operation, as the rotating frame 3 rotates, the arc-shaped rack 3103 will drive the driven gear 3104 and the rotating shaft 3101 to rotate, thereby realizing the turning and mixing of the stockpile. When the driven gear 3104 rotates to the upper part of the decomposition chamber 1, the driven gear 3104 and the arc-shaped rack 3103 separate, which can reduce the resistance when the rotating roller 2 rotates and prevent the rotating shaft 3101 from spinning idly. On the other hand, during the mixing stage of the material stacking, the pusher plate 3201 in the pusher assembly 32 needs to slide along the slide groove on the rotating frame 3 towards the center of the rotating frame 3. At this time, a space for storing the material stacking will be left between the pusher plate 3201 and the inner wall of the corrosion chamber 1. When the rotating frame 3 rotates and pushes the pusher plate 3201 to contact the material stacking, the pusher plate 3201 will contact the peak of the material stacking, which is convenient for spreading the material stacking and ensuring the uniformity of the material stacking thickness. Furthermore, since the side of the push plate 3201 is in sliding contact with the inner wall of the corrosion chamber 1, the arc-shaped rack 3103 needs to be staggered from the displacement area of ​​the push plate 3201.

[0022] To facilitate the rotation of roller 2, refer to... Figure 1 , Figure 7 As shown, a drive motor 201 is also installed on the base plate 102, and a belt assembly 202 is also provided between the drive motor 201 and the rotating roller 2 for driving the rotating roller 2 to rotate. Specifically, the belt assembly 202 includes two pulleys and a belt. The belt drive is mounted on the two pulleys, which are respectively mounted on the output shaft of the drive motor 201 and the roller 2. When working, the drive motor 201 rotates, which can drive the corresponding pulley to rotate. With the cooperation of the belt, the other pulley and the roller 2 can be pulled to rotate.

[0023] To facilitate material discharge after the sawdust has decomposed, refer to Figures 2 to 4 As shown, the inside of the rotating roller 2 is hollow, and a bidirectional lead screw 3202 is installed at the center of the rotating roller 2. A shaft cylinder 3204 is threaded at both ends of the bidirectional lead screw 3202. A diagonal brace 3203 is hinged between the two shaft cylinders 3204 and the push plate 3201. The two diagonal braces 3203 are arranged in a figure-eight shape. A crank handle 3205 is also installed at one end of the bidirectional lead screw 3202. During operation, the double-acting screw 3202 can be rotated by the crank 3205. The threads on the double-acting screw 3202 are symmetrically arranged. Therefore, when the threads on the double-acting screw 3202 are engaged with the threads on the shaft cylinder 3204, they can drive the two shaft cylinders 3204 to move synchronously in opposite directions. When it is necessary to push the stacked material outward, the two shaft cylinders 3204 can be pushed closer to slide. At this time, the push plate 3201 can be pushed outward in the slide groove by the two diagonal bracing rods 3203 until the outer side of the push plate 3201 contacts the inner wall of the corrosion chamber 1. At this time, when the rotating frame 3 pushes the push plate 3201 to rotate, the push plate 3201 can push the stacked material to slide towards the opening 103, which facilitates the push of the stacked material. In addition, since the push plate 3201 contacts and slides with the inner wall of the corrosion chamber 1, it can also clean the stacked material adhering to the inner wall of the corrosion chamber 1, achieving a self-cleaning effect. In this embodiment of the application, a through groove is also provided on the roller 2 along the axial direction. The through groove is located in the middle of the roller 2. Both diagonal support rods 3203 are passed through the through groove. The through groove can facilitate the diagonal support rods 3203 to pass through and connect with the push plate 3201. The through groove can also restrict the diagonal support rods 3203 to prevent them from swinging left and right. Furthermore, to facilitate receiving materials from hopper 103, refer to... Figure 1 As shown, brackets 101 are installed at both the front and rear ends of the corrosion chamber 1. The bottom of the brackets 101 is connected to the base plate 102. The corrosion chamber 1 is supported by the brackets 101, so that the opening 103 of the corrosion chamber 1 is at a certain height off the ground, which makes it convenient to place the transfer equipment below the opening 103 for receiving materials.

[0024] To facilitate material loading and unloading in the corrosion chamber 1, refer to Figure 1 , Figure 5 , Figure 6 As shown, the arc surface of the decomposition chamber 1 is provided with a chamber opening 103. A chamber door panel 104 is hinged to the chamber opening 103. A rubber strip is provided on the outer edge of the chamber door panel 104. A clamping plate 108 is also installed on the outer side of the chamber door panel 104. The clamping plate 108 is provided with bolts for fixing. The chamber opening 103 can facilitate the loading and unloading of materials in the decomposition chamber 1. During the decomposition process, the chamber door panel 104 can also seal the chamber opening 103, and the rubber strip can maintain the seal and reduce the loss of moisture inside the decomposition chamber 1. In this embodiment of the application, an arc-shaped rail 105 is also mounted on the arc surface of the corrosion chamber 1. The arc-shaped rail 105 is located below the chamber opening 103. A slide block 106 is slidably installed inside the arc-shaped rail 105. An arc-shaped strip 107 is also installed between the slide block 106 and the chamber door panel 104. A threaded knob for matching and fixing is also provided on the slide block 106. During the material loading and unloading stage, the silo door panel 104 needs to be opened. At this time, due to the support of the arc strip 107, the slide 106 will be pushed to slide in the arc rail 105. When the silo door panel 104 is opened to a suitable angle, the slide 106 can be fixed by the threaded knob. At this time, the arc strip 107 can support the silo door panel 104 and keep the silo door panel 104 stable. Moreover, the silo door panel 104 can also be used as a guide plate to provide guidance and support for material stacking. Based on this, when pouring material into the decomposition chamber 1, the height of the outer end face of the chamber door 104 needs to be higher than the height of the inner end face, and when discharging material out of the decomposition chamber 1, the height of the outer end face of the chamber door 104 needs to be lower than the height of the inner end face.

[0025] In summary, the specific operating procedure of the corrosion device is as follows: Loading: First, loosen the bolts and open the door panel 104. As the door panel 104 rotates, the arc strip 107 will push the slide 106 to slide in the arc rail 105. After rotating to the appropriate angle, tighten the threaded knob to fix the slide 106 and the door panel 104. Then, pour the wood chip mixture onto the door panel 104. With the guiding action of the door panel 104, the mixture can be poured into the decomposition chamber 1. Afterward, spray an appropriate amount of water into the decomposition chamber 1 and then close the door panel 104 again. Mixing: The crank 3205 drives the bidirectional screw 3202 to rotate, causing the two cylinders 3204 to move away from each other. With the cooperation of the diagonal brace 3203, the push plate 3201 can be pulled to slide along the slide groove towards the rotating frame 3. Then, the drive motor 201 is started, and with the cooperation of the belt assembly 202, the rotating roller 2 can be driven to rotate. When the rotating roller 2 drives the rotating frame 3 to rotate, the driven gear in the mixing assembly 31 can cooperate with the arc rack 3103, thereby driving the rotating shaft 3101 to rotate. When the turning roller 3102 on the rotating shaft 3101 comes into contact with the pile, it can turn over and mix the pile. As the rotating roller 2 rotates continuously, it can ensure that the pile is mixed evenly. At this time, the push plate 3201 can contact the top of the pile, which is convenient for flattening the pile and ensuring that the thickness of the pile is uniform. Turning over the material: Repeating the mixing operation at regular intervals can turn over the material, promote the aerobic respiration of bacteria in the material, and accelerate the decomposition process. Discharge: First, open the bin door 104, then use the crank 3205 to push the double-acting screw 3202 to rotate, so that the two cylinders 3204 slide close together. At this time, the diagonal brace 3203 can push the push plate 3201 away from the rotating frame 3, so that the outer side of the push plate 3201 is in contact with the inner wall of the decomposition bin 1. As the rotating frame 3 rotates, the push plate 3201 can slide against the inner wall of the decomposition bin 1, and push the stockpile towards the bin opening 103 for discharge.
