DETAILED DESCRIPTION

[0012] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but the description of the following embodiments is only used to help understand the principle and core idea of ​​the present invention, and is not intended to limit the scope of protection of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, improvements made to the present invention also fall within the scope of protection of the claims of the present invention. It should be noted that the main application object (material) of the present invention is granular, and there should be no linear debris (such as ropes, garbage bags) in the material. Example 1

[0013] like Figures 1 to 4As shown, an array-type organic fertilizer composting and turning equipment includes a shell 1, in which multiple layers of composting platforms at different heights are arranged at intervals. The specific number of layers of the composting platforms is set by those skilled in the art according to needs. When four fermentations are required, four layers of composting platforms can be set, and when three fermentations are required, three layers of composting platforms can be set. A feeding system is arranged above the top composting platform, and a discharging system 3 is arranged just below the bottom composting platform. The composting platform includes a number of closely arranged steel wires 10, and the steel wires 10 are made of stainless steel wires with a diameter of 1.2 mm, and a tensioning mechanism is arranged at the ends of the steel wires 10; during the organic fertilizer composting process, each steel wire 10 is in a state of being stretched straight and close to each other; during the organic fertilizer turning process, some of the steel wires 10 are in a bent state, and adjacent steel wires 10 are staggered. In the present embodiment, the first part of the steel wire 12 is fixedly connected to the housing 1 at both ends and is always in a straight state, the second part of the steel wire 13 is connected to the tensioning mechanism at one end and fixedly connected to the housing 1 at the other end, the tensioning mechanism includes a rotating shaft 6, and the rotating shaft 6 is provided with an anti-skid cloth layer, the second part of the steel wire 13 is fixedly connected to the rotating shaft 6, and the rotating shaft 6 is connected to the motor 7. Wherein, the second part of the steel wire 13 is arranged between the adjacent first part of the steel wire 12, and the second part of the steel wire 13 is divided into multiple groups, and the width of each group is preferably 5cm, and the first part of the steel wire 12 is also divided into multiple groups, and the number of each group is three steel wires arranged side by side as one group. A plurality of partitions 4 are used to separate the inner cavity of the housing 1 into a plurality of organic fertilizer accommodating spaces. A fluid medium channel is provided in the housing 1, and the fluid medium channel is externally connected to a fluid supply system. When the fluid medium is steam or hot water, the material can be heated.

[0014] A control method for an array-type organic fertilizer composting and turning device in this embodiment comprises the following steps: Step 1, when the material in the organic fertilizer storage space at the upper layer reaches the maturity time, the tensioning mechanism is controlled to work so that the second part of the steel wire 13 is in a bent state (the second part of the steel wire 13 is relaxed to a downwardly bent state by controlling the reverse rotation of the rotating shaft 6), and the material at this time will automatically fall through the gap between the adjacent steel wires 10 to the organic fertilizer storage space at the lower layer; Step 2, when all the materials in the organic fertilizer containing space on the upper layer have fallen down, the tensioning mechanism is controlled to work so that the second portion of the steel wire 13 is in a stretched state (the second portion of the steel wire 13 is stretched / tightened by controlling the rotating shaft 6 to rotate forward); Step 3, repeat steps 1 and 2 until the material falls from the composting platform at the bottom to the discharge system 3.

[0015] In one application scheme, a total of three layers of composting and maturing platforms are set up. The composting and maturing platforms are 3 meters long, 0.5 meters wide, and 3 meters high, with a layer spacing of 0.8 meters. The length of a single organic fertilizer accommodating space is 0.8 meters, including a first composting and maturing platform, a second composting and maturing platform, and a third composting and maturing platform. When in use: in the initial state, all stainless steel wires of each layer are in a straight state, and the material is introduced into the composting and maturing platform on the top layer (i.e., the first composting and maturing platform) through the feeding system, and then the material on the first composting and maturing platform is fermented and maturated according to the set fermentation and maturation process A; when the material on the first composting and maturing platform reaches the maturation time, the tensioning mechanism corresponding to the first composting and maturing platform is controlled to work so that the second part of the steel wire 13 is in a bent state, and the material at this time will automatically fall to the second composting and maturing platform, and then the material on the second composting and maturing platform is fermented and maturated according to the set fermentation and maturation process B, and after all the materials have fallen to the second composting and maturing platform, the tensioning mechanism corresponding to the first composting and maturing platform is controlled to work The second portion of the steel wire 13 is in a straight state (reset); when the material on the second composting platform reaches the maturity time, the tensioning mechanism corresponding to the second composting platform is controlled to work so that the second portion of the steel wire 13 is in a bent state, and the material at this time will automatically fall to the third composting platform, and then the material on the third composting platform will be fermented and matured according to the set fermentation and maturation process C, and after all the materials have fallen to the third composting platform, the tensioning mechanism corresponding to the second composting platform is controlled to work so that the second portion of the steel wire 13 is in a straight state (reset); when the material on the third composting platform reaches the maturity time, the tensioning mechanism corresponding to the third composting platform is controlled to work so that the second portion of the steel wire 13 is in a bent state, and the material at this time will automatically fall to the discharging system 3 and be sent to the next process (workshop), and after all the materials on the third composting platform have fallen to the discharging system 3, the tensioning mechanism corresponding to the third composting platform is controlled to work so that the second portion of the steel wire 13 is in a straight state (reset). If the above process is carried out continuously, the material can be continuously decomposed and turned.

[0016] In the present invention, the required parts are mainly a housing 1 (preferably a common steel plate with an anti-corrosion layer), a steel wire 10 (preferably a stainless steel wire), and a tensioning mechanism (a motor and a shaft). These parts are easy to process and directly purchase, and the required cost is very low. It only takes about 8,000 yuan to assemble a set of array-type organic fertilizer composting and turning equipment with a three-layer composting platform. Since a number of steel wires that can be close to each other are used as composting platforms, the gravity corresponding to the material is dispersed to a single steel wire, thereby providing stable support for material composting, and reflecting excellent flexibility and efficiency during turning and turning. During use, when turning and turning just begins, the material can be quickly and smoothly dropped, which is mainly due to the fact that the steel wire used has a certain hardness and flexibility, and can quickly and smoothly bend the steel wire, while it is difficult to achieve the rapid drop of the material using a wire with a lower hardness (such as nylon wire, woolen yarn), because this wire must be smoothly bent by gravity after being tightened, and adjacent wires are easily adsorbed together.

[0017] By adopting the scheme of the present invention, the cost of organic fertilizer composting and turning equipment can be reduced from the original tens of thousands of yuan / set to less than ten thousand yuan, and the floor space of the original turning equipment (turning machine) can be reduced from about twenty cubic meters to about five cubic meters. Its structure has been greatly simplified and optimized, especially only steel wires and partitions are arranged in the shell, and its operation is more convenient and flexible, maintenance is more convenient, and it will hardly cause blockage of the organic fertilizer storage space. The scheme of the present invention also has the advantages of being able to quickly adjust the internal structure of the material during the fermentation and composting process, and it only needs to control the tensioning mechanism corresponding to the composting platform to work so that the second part of the steel wire 13 is slightly bent downward (the downward displacement of the middle part of the second part of the steel wire 13 does not exceed 1mm), so that part of the material can be slightly sunk, thereby adjusting the internal structure of the material.
