Description

Technical Field

[0001] The utility model relates to the technical field of urban sludge treatment, in particular to a device for cultivating earthworm seedlings using urban sludge. Background Art

[0002] Municipal sludge treatment equipment is used to recycle and treat sludge in cities. Conventional treatment methods such as incineration and landfill cannot fundamentally solve the pollution problem. When earthworms are cultured using municipal sludge, the municipal sludge is not fermented but directly treated biologically, which greatly improves the municipal sludge treatment effect. At the same time, it is conducive to the long-term domestication of earthworms and is suitable for large-scale cultivation of earthworms. However, the equipment and methods for cultivating earthworms with municipal sludge are often more complicated to operate, especially for the necessary processing work required for breeding large amounts of sludge soil. For example: Patent No. CN 212035520U discloses a municipal sludge culture earthworm seedling cultivation device, which can adjust the three groups of culture boxes on the mounting frame to the operating height accustomed to the staff, thereby improving the operation convenience of the municipal sludge culture earthworm seedling cultivation device; it includes a mounting frame and three groups of culture boxes, the left front and left rear sides of the mounting frame are each provided with a left support leg, the right front and right rear sides of the mounting frame are each provided with a right support leg, the middle part of the mounting frame is evenly provided with three groups of placement plates, and the tops of the three groups of culture boxes are each provided with a holding groove; it also includes two groups of power motors, two groups of power wheels, two groups of mounting plates, two groups of steel ropes, two groups of limit sliders, two groups of blocks and lifting plates, the three groups of culture boxes are respectively placed on the tops of the three groups of placement plates, the outer ends of the two groups of right legs are each provided with sliding holes, and the outer side walls of the two groups of power wheels are each provided with annular grooves. Although the device can make full use of space through its vertical structure, it is more troublesome to operate each layer of culture boxes, and it is inconvenient to water and loosen the soil.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figures 1 to 3 As shown, a device for cultivating earthworm seedlings in urban sludge includes a first column 4 and a second column 1 arranged in front and back, a first rotating shaft 6 is provided on the side of the first column 4 opposite to the second column 1, the first rotating shaft 6 is fixedly connected to the frame 3, and also includes a control device 5 for controlling the rotation of the first rotating shaft 6. Specifically, the control device 5 is a motor, a plurality of culture boxes 9 are provided in the frame 3, a second rotating shaft 8 is provided between the culture box 9 and the frame 3, a transmission belt 7 is provided between the plurality of second rotating shafts 8, a fixed shaft 2 is provided between one of the culture boxes 9 and the second column 1; and also includes a watering mechanism and a loosening mechanism arranged on the frame.

[0022] Working principle: The control device 5 drives the first rotating shaft 6 to rotate, and the first rotating shaft 6 drives the frame 12 to rotate. Since one of the culture boxes 9 is relatively fixed to the second column 1, when the frame 12 rotates, the culture box 9 remains stationary, and the other culture boxes 9 move under the drive of the frame 12. Since a transmission belt 7 is provided between the second rotating shafts 8 between each culture box 9, the direction of each culture box 9 is consistent and the top is always facing upward, so that the position of each culture box 9 can be adjusted to a vertical position, such as Figure 3 As shown, or adjust to flat, such as Figure 2 As shown, when in a vertical position, the space can be fully utilized. When in a flat position, it is convenient to water and loosen the soil of each culture box 9 at the same time. Moreover, each culture box 9 can be exposed to light, providing the soil with appropriate humidity, oxygen and temperature, which is conducive to the activity of earthworms.

[0023] It should also be noted that, in this embodiment, three culture boxes 9 are provided, and the middle culture box 9 is fixedly provided in the middle. In actual production, more culture boxes 9 can be provided, and the culture box 9 at one end is fixedly provided. When adjusted to a vertical position, the remaining culture boxes 9 are located above the culture box 9 and are not restricted by the height below.

[0024] Preferably, the sprinkler mechanism includes a bracket 12 arranged on the frame 3, and the bracket 12 is in an inverted "U" shape. A water tank 13 is provided on the top of the bracket 12, and a nozzle 15 is provided on the bottom that is adapted to the culture box 9 and connected to the water tank 13. The specific connecting pipeline can be set in the bracket 12, and the water tank 13 is provided with a sealing cover. When the position of the water tank 13 changes, there will be no water leakage. The nozzles 15 can be provided with separate switches. When watering, the corresponding nozzle 15 is selected to be turned on according to the usage of the culture box 9.

[0025] Preferably, the loosening mechanism includes a lifting rod 10, an electric telescopic rod 14 is provided between the lifting rod 10 and the bracket 12, and a plurality of loosening heads 11 are provided at the bottom of the lifting rod 10. Specifically, the electric telescopic rod 14 is a cylinder, which controls the lifting and lowering of the lifting rod 10 through the electric telescopic rod 14, drives the loosening head 11 to rise and fall, inserts it into the soil, turns the soil, and increases the oxygen content of the soil.

[0026] Preferably, the lifting rod 10 is provided with two front and rear ones, and the electric telescopic rod 14 is tilted, so that the loosening head 11 has weight distribution in both the vertical and horizontal directions, can contact with a wider range of soil, and has a good loosening effect.

[0027] Preferably, the loosening head 11 is conical and has a plurality of soil leakage holes, which facilitates the insertion of the loosening head 11 into the soil. The soil can pass through the soil leakage holes, which has a certain crushing effect and improves the loosening effect.

[0028] Preferably, a through hole is opened on the frame 3, and the fixed shaft passes through the through hole and is rotatably connected to the through hole. The fixed shaft can also provide a certain support for the frame 12, thereby improving the stability of the device.

[0029] Preferably, the bottoms of the first column 4 and the second column 1 are both provided with bases with fixing holes. Since the watering mechanism and the loosening mechanism will make the center of gravity of the device unstable when the device is adjusted to a vertical position, the base can be used to stabilize and fix the device.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
