DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] Referring to the accompanying Figure 1 , the accompanying Figure 2 , the accompanying Figure 10 and the accompanying Figure 11 , the embodiments of the present application disclose a composting device, which comprises a support 1, the bottom of the support 1 abuts against the ground, for supporting and fixing, a horizontal rotating shaft 2 is arranged on the support 1, the support 1 is rotationally connected with a drum type composting box 3 through the rotating shaft 2, the drum type composting box 3 comprises two first cover bodies 31 and a plurality of barrel wall units 32, the two first cover bodies 31 are located in vertical planes and oppositely arranged, the two first cover bodies 31 are circular and the centers of the circles are rotationally connected with the support 1 through the rotating shaft 2; the barrel wall unit 32 comprises a plurality of three-dimensional components 321, the plurality of three-dimensional components 321 are linearly arrayed and connected with each other through planar components 322 between adjacent two three-dimensional components 321, the three-dimensional components 321 and the planar components 322 are made of the same elastic material, the barrel wall unit 32 has a first state of being unfolded into a plane and a second state of being bent into an arc shape, different barrel wall units 32 are detachably connected, so that when the barrel wall unit 32 is in the second state, the plurality of barrel wall units 32 can be enclosed into a cylindrical structure, the two ends of the cylindrical structure are detachably connected with the two first cover bodies 31 respectively for sealing, the axis of the cylindrical structure passes through the centers of the two first cover bodies 31, so that the cylindrical structure can rotate around its axis, and at least one second cover body 4 which can be opened and closed is arranged on one of the barrel wall units 32.

[0047] In actual use, the second cover body 4 is opened, and materials are put into the inside of the drum type composting box 3 for composting. During the composting process, the drum type composting box 3 can be rotated through the action of the rotating shaft 2 on the support 1, so that the materials in the inside of the drum type composting box 3 are tumbled and stirred. Since the drum type composting box 3 is composed of two first cover bodies 31 and a plurality of barrel wall units 32, and the first cover body 31 and the barrel wall unit 32 and the adjacent two barrel wall units 32 are detachably connected, the drum type composting box 3 is detachable. Therefore, the whole drum type composting box 3 does not need to be made at one time, but a plurality of smaller parts are made and then assembled, so that the drum type composting box 3 is obtained, which greatly reduces the manufacturing difficulty. After the drum type composting box 3 is disassembled, it can be stacked and placed, and the cavity in the inside of the drum type composting box 3 no longer occupies space, so that the storage space occupied is smaller, and the storage and transportation are facilitated. After a part of the drum type composting box 3 is damaged, the corresponding part can be replaced, so that the drum type composting box 3 can be normally used, which is convenient and fast, and does not cause waste of resources. In general, the composting device in the present application is detachable, and is convenient for manufacturing, storage, transportation and maintenance.

[0048] It should be noted that the specific connection mode of “the support 1 is rotatably connected with the drum type composting box 3 through the rotating shaft 2” is not limited in the present application, and can be flexibly selected according to actual needs. For example, the rotating shaft 2 can be fixedly connected with the support 1, and then the composting box 3 is rotatably connected with the rotating shaft 2. Alternatively, the rotating shaft 2 can be rotatably connected with the support 1, and then the composting box 3 is fixedly connected with the rotating shaft 2. Through the above modes, the rotating function of the drum type composting box 3 can be realized.

[0049] It should be noted that the detachable connection mode between the first cover body 31 and the barrel wall unit 32, the detachable connection mode between the adjacent two barrel wall units 32, and whether only one detachable connection mode is used when the two parts are connected are not limited in the present application. Therefore, they can be selected according to actual needs. For example, the buckle connection and the threaded connection can be used for detachable connection. The buckle connection is convenient for quick connection and positioning of the two parts, and the threaded connection can further reinforce the connection part of the two parts.

[0050] Since the material of the three-dimensional member 321 and the planar member 322 is the same, the barrel wall unit 32 can be directly formed by injection molding or mold pressing. Although the barrel wall unit 32 is in the second state of being bent and arc-shaped when the drum type composting box 3 is assembled, it has the first state of being unfolded into a plane. Therefore, a planar part can be directly made, and then it is bent. The structure is simpler when the mold is opened, and the manufacturing is more convenient and fast.

[0051] Referring to the drawings Figure 10 and the drawings Figure 11, the three-dimensional member 321 is made of elastic material, which is the same as the material of the planar member 322, so as to facilitate the manufacturing of the cylinder wall unit 32. Although the three-dimensional member 321 is made of elastic material, it is three-dimensional in structure, so it is more stable and less likely to deform greatly, and can be used as the side wall of the drum-type compost bin 3. The planar member 322 is made of elastic material, because the planar structure is relatively weak in resisting deformation, so it is easy to deform, and the cylinder wall unit 32 is easy to bend into an arc shape.

[0052] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 13 - the accompanying drawings Figure 16 Before the compost bin is assembled, the cylinder wall unit 32 can be unfolded into a planar first state, which is convenient for manufacturing, storage and transportation. When the compost bin is assembled, the cylinder wall unit 32 can be bent into an arc-shaped second state, so that multiple cylinder wall units can be connected in sequence and form a cylindrical structure.

[0053] Referring to the accompanying drawings Figure 1 , the accompanying drawings Figure 4 and the accompanying drawings Figure 5 There are many structures that can support objects, and one of them is introduced in this embodiment. Specifically, the support 1 includes two first support members 101, two second support members 102, and two third support members 103. The first support member 101 is basically inverted V-shaped, and the two first support members 101 are oppositely arranged and the tops are respectively connected and fixed to the opposite ends of the rotating shaft 2. The second support member 102 is basically L-shaped, and one side of the second support member 102 is horizontally arranged, and the other side is inclined in the vertical plane. The horizontal side of the second support member 102 abuts against the ground for support, and the top ends of the inclined sides of the two second support members 102 are respectively connected to the two bottom ends of one first support member 101 by plug-in buckle connection. The third support member 103 is basically L-shaped, and one side of the third support member 103 is horizontally arranged, and the other side is inclined in the vertical plane. The horizontal side of the third support member 103 abuts against the ground for support, and the top ends of the inclined sides of the two third support members 103 are respectively connected to the two bottom ends of the other first support member 101 by plug-in buckle connection. The end of the horizontal side of the third support member 103 and the end of the horizontal side of the corresponding second support member 102 are connected by plug-in buckle connection, so that the two first support members 101, the two second support members 102 and the two third support members 103 can form a structure that is stable as a whole, thereby supporting the rotating shaft 2 and the drum-type compost bin 3.

[0054] Through the design of the above structure, the support 1 can form a triangular support structure, which is more stable and less likely to shake and fall; and the support 1 is composed of a plurality of rod pieces, which uses less material and has lower manufacturing cost; in addition, since the support 1 is composed of two first support pieces 101, two second support pieces 102 and two third support pieces 103, the first support piece 101 is basically inverted V-shaped, the second support piece 102 is basically L-shaped, and the third support piece 103 is basically L-shaped, and the first support piece 101 and the second support piece 102 are detachably connected, the second support piece 102 and the third support piece 103 are detachably connected, and the first support piece 101 and the third support piece 103 are detachably connected, so the support 1 can be disassembled into a plurality of planar structures and stacked together, and like the detachable drum-type composting box, has the advantages of convenient manufacturing, storage, transportation and maintenance.

[0055] Referring to the accompanying drawings Figure 5 -attached Figure 9 The detachable connection mode and structure have many kinds, and one of them is introduced in the embodiment. Specifically, the two bottom ends of the first support piece 101, the end portions of the horizontal side of the second support piece 102 are provided with insertion slots 104, the top end of the inclined side of the second support piece 102, the top end of the inclined side of the third support piece 103, and the end portion of the horizontal side of the third support piece 103 are provided with insertion rods 105, the insertion rods 105 can be inserted into the inside of the insertion slots 104 to be connected by plugging; the sidewall of the insertion slot 104 is provided with a first through hole 106, the end portion of the insertion rod 105 is provided with a groove 107, the sidewall of the groove 107 is provided with a second through hole 108 corresponding to the first through hole 106, the groove 107 is provided with an elastic piece 109, one end of the elastic piece 109 is connected to a limiting plate 110, the end of the limiting plate 110 away from the elastic piece 109 is provided with a limiting protrusion 111, the limiting plate 110 is located in the groove 107 and has a size larger than that of the second through hole 108, so as to prevent the limiting plate 110 from passing through the second through hole 108, the limiting protrusion 111 has a size smaller than that of the second through hole 108 and the first through hole 106, so that after the first through hole 106 and the second through hole 108 are aligned, the limiting protrusion 111 can pass through the first through hole 106 and the second through hole 108, thereby fixing the relative positions between the first support piece 101 and the second support piece 102, or between the first support piece 101 and the third support piece 103, or between the second support piece 102 and the third support piece 103.

[0056] Through the design of the above structure, before plugging connection, the limiting protrusion 111 is pressed into the second through hole 108, then the corresponding two components are plugged and connected through the cooperation of the plug rod 105 and the plug slot 104, in the process of plugging connection, when the first through hole 106 and the second through hole 108 are aligned, under the elastic force of the elastic member 109, the limiting protrusion 111 will automatically pass through the first through hole 106 and the second through hole 108, thereby fixing the relative position of the corresponding two components, the whole process does not need to use additional tools for auxiliary operation, and has the advantages of simple structure, convenient disassembly and assembly, reliable connection and the like.

[0057] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 10 There are various modes and structures of detachable connection, and one of them is introduced in the embodiment. Specifically, a third through hole 5 is arranged on one of the barrel wall units 32, the third through hole 5 is in a stepped shape and has an outer size larger than an inner size, one end of the second cover body 4 is located in the third through hole 5 and rotationally connected to the barrel wall unit 32, and the other end of the second cover body 4 is provided with a limiting assembly 6. After the second cover body 4 closes the third through hole 5, the limiting assembly 6 can limit the second cover body 4.

[0058] Through the design of the above structure, after the second cover body 4 is opened, it does not need to be specially placed, and after being closed, the relative position of the second cover body 4 and the barrel wall unit 32 can be more conveniently fixed.

[0059] Referring to the accompanying drawings Figure 12 There are various structures capable of limiting and fixing effects, and one of them is introduced in the embodiment. Specifically, the limiting assembly 6 comprises a rotating member 61 and a limiting member 62. The rotating member 61 is rotationally connected to the second cover body 4, and the two ends of the rotating member 61 are located on the two sides of the second cover body 4. One end of the rotating member 61 located on the outer side of the second cover body 4 is used for holding and driving rotation. The limiting member 62 is fixedly connected to one end of the rotating member 61 located on the inner side of the second cover body 4. After the second cover body 4 is closed, one end of the limiting member 62 can be rotated to the barrel wall unit 32 to limit the second cover body 4. One end of the limiting member 62 can also be rotated to the second cover body 4 to release the limitation of the second cover body 4.

[0060] Through the design of the above structure, after the second cover body 4 is closed, the second cover body 4 can be limited or released by only driving the rotating member 61 to rotate, and the structure is simple.

[0061] Referring to the accompanying drawings Figure 1 The composter often needs to be rotated during use, and the rolling composting tank 3 in the application also needs to be rotated. In order to facilitate rotation, the following design is made in the embodiment. Specifically, recessed handles 7 are arranged on the barrel wall unit 32 and the second cover body 4.

[0062] Through the design of the above structure, the handle 7 on the barrel wall unit 32 can assist in rotating the drum composting box 3, and the handle 7 on the second cover body 4 can assist in rotating the drum composting box 3 or assisting in opening and closing the second cover body 4. In addition, since the handle 7 is designed in a groove type, the smoothness of the surface of the drum composting box 3 can be maintained, and the appearance is more beautiful.

[0063] Referring to the accompanying drawings Figure 3 After the composting device is manufactured or assembled, the volume of the internal cavity of the drum composting box 3 is fixed, but the amount of material placed each time for composting is not necessarily fixed. If the amount of material for composting is too small, the average thickness of the material in the internal cavity of the drum composting box 3 is too small, which is not conducive to the occurrence of the composting heat generation process and the like, and the internal cavity of the entire drum composting box 3 becomes dirty during the composting process, which is not convenient for cleaning. Therefore, in order to solve the above problems, at least one partition plate 8 is arranged in the internal cavity of the drum composting box 3 in the embodiment, so as to divide the internal cavity of the drum composting box 3 into a plurality of cavities that are not connected to each other, and the number of the second cover bodies 4 is consistent with the number of the cavities.

[0064] Through the design of the above structure, the number of cavities used can be determined according to the amount of material, so that the thickness of the material can always meet the standard, the composting heat generation process and the like can be easily generated, and the entire drum composting box 3 is not contaminated by dirt, which is convenient for cleaning.

[0065] Referring to the accompanying drawings Figure 3 During the composting process, a necessary step is stirring. The stirring can make the composting material contact with air to supply oxygen, make the composting material mix more uniformly, make the composting material rot more completely, and be beneficial to the loss of water and the drying of the material. Therefore, in the embodiment, at least one stirring blade 9 is arranged in each cavity. The stirring blade 9 is fixedly connected to the rotating shaft 2, the drum composting box 3 is rotatably connected to the rotating shaft 2, and the rotating shaft 2 is fixedly connected to the support 1.

[0066] Through the design of the above structure, when the drum composting box 3 rotates, the stirring blade 9 can relatively rotate. During the rotation of the drum composting box 3, the material will constantly roll and collide with the stirring blade 9, so that the stirring blade 9 can scatter the material gathered together, and play a stirring role.
