Description

Technical Field

[0001] This utility model belongs to the field of aerobic composting technology, and specifically relates to a portable compost maturity detection device. Background Technology

[0002] With rapid industrialization and urbanization, the output of organic waste has increased dramatically, posing a serious threat to the environment. Therefore, realizing the resource utilization of organic waste is of great significance. Composting, as an effective solid waste treatment method, can transform organic waste into high-quality organic fertilizer, not only reducing the impact of solid waste on the ecological environment but also providing abundant nutrients to the soil. Composting technology not only renders pathogens in waste harmless through high-temperature fermentation under the action of microorganisms, but also decomposes and stabilizes organic matter, ultimately achieving full decomposition. Furthermore, it can be further processed into pollution-free organic fertilizer. Composting organic waste enables the effective resource utilization of organic waste.

[0003] Compost maturity refers to the degree to which organic matter in compost has been stabilized and rendered harmless through the action of microorganisms, and is one of the important indicators of compost quality. Currently, tools for testing compost maturity have limited functionality and specific problems: 1. They can only test a single type of compost sample, resulting in low efficiency; 2. Since the main data for maturity testing involves analyzing the root growth length at seed germination, existing technologies often detect roots that are bent or entangled during growth, making measurement difficult and compromising accuracy; 3. They cannot precisely control the liquid supply as needed; 4. They are not suitable for testing in different locations. All these problems affect the accuracy and comparability of the results, leading to unreliable and inaccurate determinations of compost maturity.

[0004] Therefore, providing a portable compost maturity testing device is of great significance for realizing the resource utilization of organic waste. Utility Model Content

[0026] Exemplary embodiments, features, and aspects of the present invention will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0027] This utility model provides a portable compost maturity testing device, such as... Figures 1-3 As shown, it includes the device body, partition plate 1, first baffle assembly, second baffle assembly, planting hole 2 and root channel 3.

[0028] The partition plate 1 is located inside the device body and the bottom of the partition plate 1 is sealed to the inner bottom of the device body by adhesive, so as to ensure that the separated areas maintain independent and sealed spaces and prevent liquid from seeping into each other.

[0029] The interior of partition plate 1 is the first area A, where the compost sample to be tested and the blank control group liquid are placed. The blank control group liquid can be deionized water or distilled water. The area between partition plate 1 and the inner wall of the device body is the second area B, used for seed germination.

[0030] The partition plate 1 is provided with a liquid channel for supplying liquid to the seeds. In this invention, the liquid channel is preferably made of filter paper cotton core 4. The partition plate 1 is also provided with scale markings for controlling the liquid supply volume. There are four filter paper cotton cores 4, which are respectively set in the four liquid supply areas and the four germination areas corresponding to the liquid supply areas. The first ends of the four filter paper cotton cores 4 are respectively located in the four liquid supply areas of the first region A and are fixed in the slots 5 at the corresponding scale markings according to the preset liquid supply volume.

[0031] In a preferred embodiment of this utility model, the device body is a circular box structure with an open top and a closed bottom, and the partition plate 1 is a cylindrical structure with open ends. The device body and the partition plate 1 are coaxially arranged, that is, the device body is divided into a first region A and a second region B by the partition plate 1.

[0032] Preferably, the inner and outer walls of the partition plate 1 are evenly distributed with slots 5 for fixing and limiting the filter paper cotton core 4, and the filter paper cotton core 4 can move up and down within the slots 5. The filter paper cotton core 4 is bent within the slots 5, with its first end located in the liquid supply area, and its second end extending downward along the outer wall of the partition plate 1 past the top to the corresponding germination area. The first end of the filter paper cotton core 4 can be fixed in the slot 5 at the corresponding position according to the preset liquid supply volume, or the scale marking position of its first end can be adjusted upward or downward according to changes in the liquid supply volume.

[0033] The first baffle assembly is disposed within the first region A and divides the first region A into four liquid supply zones: a first liquid supply zone A1, a second liquid supply zone A2, a third liquid supply zone A3, and a fourth liquid supply zone A4. In a preferred embodiment of this invention, the first baffle assembly has a cross-shaped structure and includes a first inner zone baffle 111, a second inner zone baffle 112, a third inner zone baffle 113, and a fourth inner zone baffle 114. The outer edges of the four inner zone baffles of the first baffle assembly are sealed to the inner wall of the partition plate 1 by adhesive bonding, and the bottom edge of the first baffle assembly is sealed to the inner bottom of the device body by adhesive bonding. The cross-shaped structure of the first baffle assembly divides the first region A into four liquid supply zones of the same structure and size. The sealed and fixed connection prevents different liquids in the four liquid supply zones from leaking into each other, thus avoiding affecting the accuracy of the experimental results.

[0034] Preferably, one of the supply areas of the first region A, namely the first supply area A1, contains distilled water or deionized water as a blank control group. The other three supply areas, namely the second supply area A2, the third supply area A3, and the fourth supply area A4, can contain different types of compost samples to be tested. The maturity of the three types of compost samples to be tested can be detected simultaneously. The three different compost samples to be tested are compared with the blank control group to form comparative data and obtain better test results.

[0035] The second baffle assembly is located within the second region B, dividing the second region B into four germination zones: a first germination zone B1, a second germination zone B2, a third germination zone B3, and a fourth germination zone B4. Each germination zone has a filter element at its bottom that contacts the liquid channel. The number of germination zones corresponds to the number of liquid supply zones. In this invention, the filter element is filter paper 6 laid at the bottom of each germination zone. The filter paper 6 contacts the second end of the filter paper core 4 to transfer liquid onto the filter paper 6 for seed germination.

[0036] In a preferred embodiment of this utility model, the second baffle assembly includes four outer baffles of the same structure and size: a first outer baffle 121, a second outer baffle 122, a third outer baffle 123, and a fourth outer baffle 124. The two side edges of each outer baffle are respectively sealed to the outer wall of the partition plate 1 and the inner wall of the device body by adhesive. The bottom edge of each outer baffle is sealed to the bottom of the device body by adhesive, so as to prevent liquid from seeping into the four germination zones formed by the interconnection of the four outer baffles, which would lead to inaccurate experimental data.

[0037] In this invention, the four outer baffles are all located within the second region B and on the outside of the first baffle assembly. The inner sides of the four outer baffles correspond one-to-one with the outer edges of the first baffle assembly. Specifically, the inner edge of the first outer baffle 121 corresponds to the outer edge of the first inner baffle 111, the inner edge of the second outer baffle 122 corresponds to the outer edge of the second inner baffle 112, the inner edge of the third outer baffle 123 corresponds to the outer edge of the third inner baffle 113, and the inner edge of the fourth outer baffle 124 corresponds to the outer edge of the fourth inner baffle 114. The purpose is to make the first liquid supply area A1 correspond to the first germination area B1, the second liquid supply area A2 correspond to the second germination area B2, the third liquid supply area A3 correspond to the third germination area B3, and the fourth liquid supply area A4 correspond to the fourth germination area B4. The liquid from the four supply zones of the first zone A is used to supply the seeds in the germination zone of the corresponding second zone B.

[0038] Multiple planting holes 2 are fixedly located on the outer circumference of the lower part of the partition plate 1 and are evenly distributed for placing preferred seeds. The planting holes 2 have openings at the top and bottom. The upper opening is used to put the seeds in, and the lower opening is used to communicate with the root channel 3 and make the seeds contact the filter paper 6 to ensure liquid absorption.

[0039] Multiple root channels 3 are connected to the bottom of corresponding planting holes 2 and extend radially to the wall of the device body. The root channels 3 are equipped with scale markings for intuitive measurement of root length.

[0040] Specifically, the root channel 3 is a C-shaped straight groove structure with its opening facing downwards. The edge of the opening at the first end of the root channel 3 is fixedly connected to the edge of the opening at the bottom of the planting hole 2, and the second end of the root channel 3 extends to the main body of the device. The root channel 3 is set straight to ensure that the seed roots grow in a straight line, without bending or tangling, and to facilitate measurement.

[0041] In a preferred embodiment of this utility model, a space for laying filter paper 6 is provided between the planting hole 2 and the root channel 3 and the inner bottom of the device body, and the upper end of the filter paper 6 is in contact with the bottom opening of the planting hole 2 and the root channel 3, so that the seed roots can absorb liquid in all directions.

[0042] The specific embodiments of this utility model are further described below:

[0043] This utility model includes a device body, which is divided into two regions. The first region A is located in the inner layer of the device body. The first region A is divided into four liquid supply areas by a partition plate 1, which are used for dissolving the fertilizer sample to be tested and for holding the liquid of the blank control group, respectively.

[0044] The second region B is located on the outer layer of the device body. The second region B is divided into four germination zones by an outer baffle. Each germination zone has filter paper 6 at its bottom, serving as the necessary germination bed for seed germination. The partition plate 1 has graduation markings, and its inner and outer walls are provided with slots 5. A bent filter paper core 4 with its opening facing downwards is placed in the slot 5. The filter paper core 4 can be moved up or down to adjust the required liquid supply. The bottom of the filter paper core 4 extends through the planting hole 2 and the seed germination channel 3 to contact the bottom of the germination zone and the filter paper 6.

[0045] The bottom of the partition plate 1 is provided with a planting hole 2, in which standard test seeds are placed. The planting hole 2 is connected to the seed germination channel 3, which extends to the inner wall of the device body located at the edge of the second region B.

[0046] This invention dissolves three different types of compost samples in three liquid supply zones, while a blank control group is set up in one of the liquid supply zones using distilled water or deionized water. The liquids of the three test groups and the blank control group are absorbed by the filter paper cotton core 4 set on the separator plate 1 and transferred to the filter paper 6. The seeds germinate in the planting hole 2 and the roots grow straight along the root channel 3.

[0047] This invention uses graduations on the partition plate 1 to set the liquid supply volume, and without the aid of any tools, directly measures the length of the seed roots using graduations on the root channel 3. Then, an automatic root length measurement program automatically calculates the average root length and seed germination rate. The seed germination index, as a biological method, can quickly and effectively assess the maturity of compost.

[0048] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
