[0020] The present invention is further described below with reference to the accompanying drawings and specific embodiments. However, the following examples are intended only to facilitate understanding of the principles and core concepts of the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that improvements to the present invention made by a person of ordinary skill in the art without departing from the principles of the present invention would fall within the scope of protection of the claims. It should be noted that the present invention is primarily intended for granular materials, and linear debris (such as ropes or garbage bags) must not be present in the material. Example 1

[0021] like Figures 1 to 4 As 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 provided above the top composting platform, and a discharging system 3 is provided just below the bottom composting platform. The composting platform includes a number of closely arranged steel wires 10, each of which is made of stainless steel wire with a diameter of 1.2 mm, and a tensioning mechanism is provided at the end of the steel wire 10. During the composting process, each steel wire 10 is in a straight and close-fitting state. During the 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 portion of the steel wire 12 is fixedly connected to the housing 1 at both ends and is always in a stretched state. The second portion of the steel wire 13 is connected to a tensioning mechanism at one end and fixedly connected to the housing 1 at the other end. The tensioning mechanism includes a rotating shaft 6, on which an anti-skid fabric layer is provided. The second portion of the steel wire 13 is fixedly connected to the rotating shaft 6, which is connected to the motor 7. Among them, the second portion of the steel wire 13 is provided between adjacent first portion of the steel wire 12. The second portion of the steel wire 13 is divided into multiple groups, each group preferably having a width of 5 cm. The first portion of the steel wire 12 is also divided into multiple groups, each group having three steel wires arranged side by side. A plurality of partitions 4 are used to separate the inner cavity of the housing 1 into several organic fertilizer storage spaces. A fluid medium channel is provided in the housing 1. 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.

[0022] A control method for an array-type organic fertilizer composting and turning device in this embodiment comprises the following steps:

[0023] Step 1: When the material in the organic fertilizer accommodating space on the upper layer reaches the maturity time, the tensioning mechanism is controlled to work so that the second portion of the steel wire 13 is in a bent state (the second portion of the steel wire 13 is relaxed to a downwardly bent state by controlling the rotation shaft 6 to reverse). At this time, the material will automatically fall through the gap between the adjacent steel wires 10 and into the organic fertilizer accommodating space on the lower layer;

[0024] Step 2: After all the materials in the organic fertilizer storage space on the upper layer have fallen, the tensioning mechanism is controlled to work so that the second portion of the steel wire 13 is in a straightened state (the second portion of the steel wire 13 is tightened / tightened by controlling the rotating shaft 6 to rotate forward);

[0025] Step 3: Repeat steps 1 and 2 until the material falls from the composting platform at the bottom to the discharge system 3.

[0026] In one application scheme, a total of three layers of composting platforms are set up, which 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 the first composting platform, the second composting platform, and the third composting platform. When in use: in the initial state, all the stainless steel wires of each layer are in a straight state, and the materials are introduced into the composting platform on the top layer (that is, the first composting platform) through the feeding system, and then the materials on the first composting platform are fermented and composted according to the set fermentation and composting process A; when the material on the first composting platform reaches the composting time, the tensioning mechanism corresponding to the first composting 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 platform, and then the materials on the second composting platform are fermented and composted according to the set fermentation and composting process B, and after all the materials have fallen to the second composting platform, the tensioning mechanism corresponding to the first composting platform is controlled to work The material on the third compost maturing platform is then fermented and matured according to the set fermentation and maturation process C, and after all the materials have fallen onto the third compost maturing platform, the tensioning mechanism corresponding to the second compost maturing platform is controlled to work so that the second part of the steel wire 13 is in a stretched state (reset); when the material on the third compost maturing platform reaches the maturation time, the tensioning mechanism corresponding to the third compost maturing platform is controlled to work so that the second part of the steel wire 13 is in a stretched state (reset), and the material on the third compost maturing platform is automatically dropped to the discharging system 3 and sent to the next process (workshop), and after all the materials on the third compost maturing platform have fallen to the discharging system 3, the tensioning mechanism corresponding to the third compost maturing platform is controlled to work so that the second part of the steel wire 13 is in a stretched state (reset). If the above process is carried out continuously, the material can be continuously composted and turned over.

[0027] In the present invention, the required parts are mainly the shell 1 (preferably a plain steel plate with an anti-corrosion layer), the steel wire 10 (preferably a stainless steel wire), and the tensioning mechanism (motor and shaft). These parts are easy to process and can be purchased directly, and the required cost is very low. It only costs 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 distributed to a single steel wire, thereby providing stable support for material composting and showing excellent flexibility and efficiency during turning and turning. During use, when turning and turning just begins, the material can fall quickly and smoothly. This is mainly due to the fact that the steel wire used has a certain hardness and flexibility, which can quickly and smoothly bend the steel wire. However, it is difficult to achieve a rapid drop of the material by using a silk thread with a lower hardness (such as nylon thread or wool thread) because such a silk thread must rely on gravity to bend smoothly after being tightened, and adjacent silk threads are easily adsorbed together.

[0028] By adopting the solution of the present invention, the price of organic fertilizer composting and turning equipment can be reduced from the original tens of thousands of yuan per 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 since only steel wires and partitions are arranged in the shell, making it more convenient and flexible to operate, and easier to maintain, and almost no clogging of the organic fertilizer storage space will occur. The solution of the present invention also has the following advantages: the internal structure of the material can be quickly adjusted during the fermentation and composting process, and it only needs to control the tensioning mechanism corresponding to the compost 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 1 mm), so that part of the material can be slightly sunk, thereby adjusting the internal structure of the material.
