Abstract

PURPOSE: An automatic selector of an earthworm feces is provided to easily repair at out of order and reduce the operating expenses and the installation investment. CONSTITUTION: The automatic selector of an earthworm feces comprises; a motor(7), a earthworm selecting pin(3-10), a feces selecting screen and a micro-structure selecting screen. The mixed material mixing some earthworm, feces, overs is put into the earthworm feces selector being rotated after being connected with the motor by a conveyor belt(1) or manpower or tools like a shovel, an excavator, a skid loader and the mixed material is moved into the outlet by the gravity in the drum being rotated after being inclined as 1-5 deg. The earthworm is dropped to a earthworm selecting box(5) after being selected by the earthworm selecting pin(length 30mm-150mm, 3-10) being connected with the feces selecting screen. The earthworm in the mixed material is strained to the earthworm selecting pin and the earthworm is fallen from the upper part of the earthworm selecting box by the gravity and then it is selected after being fallen to the selecting box. The feces and overs are selected by the feces selecting screen.

Description

Earthworm fecal soil automatic sorting device {Wormcasting separator}

The present invention is an apparatus designed for effective screening of earthworms and fecal soil, which are by-products generated after treatment in organic waste treatment technology using earthworms, which are recently spotlighted. It is installed inside the drum by injecting the earthworm, fecal soil, and earthworm, which is not processed and mixed with fecal soil and discharged (overs: OVERS). It is an automatic sorting device designed to separate the earthworm, the feces and the overs by the earthworm sorting pin and the fecal soil sorting screen.

Earthworm fecal soils are widely known worldwide for their useful value as compost. Fecal soil has a monolithic structure, which maintains pores in the soil, drains well, and is highly breathable, and is effective for growing plant roots.In addition to the existing fertilizers, N, P205 and K20, it contains carbon, amine acids, and organic substances. It contributes greatly to plant growth and has a deodorizing effect, effectively eliminating odors generated during treatment of organic waste using earthworms.

Due to the physical, chemical, and biological excellence of such feces, it has been recently developed as a deodorant, a desulfurizer, and a spawning agent, and its scope of use is expanding. It was established as a lake and has a legal basis for sales of fecal soil, and its market area is available for sale as landfill soil, soil improver, landscaping, reclaimed land, and green soil.

In the existing earthworm breeding facilities, there are various methods for sorting earthworms and fecal soil according to the purpose and condition of the fecal soil. Generally, the method using the earthworm habit is mainly used. When the earthworm eats the prey that is suddenly raised in breeding, it feeds new food in the upper part of the breeding ground, and the earthworm rises to the top along with the new food. As the series of processes progress, the breeding height gradually increases. If the breeding to some extent, the earthworms are separated in search of new food and the skid loader and sorter are turned upside down to sort the feces. Fecal soil screening of this process has the following problems.

First, the screening work is long, although a lot of manpower is required by most manpower methods. As a result, the work efficiency is lowered, resulting in an increase in production cost, which lowers the competitiveness.

Second, fecal soil currently sold contains impurities such as soil and sand, and non-sulfide, and the particle size is not constant, and earthworms are not selected. Existing fecal soil sorter is used to remove large sebum, which is a problem when selling fecal soil, not only earthworms, but also earthworms, which contains mixed substances with fecal soil, and sells fecal soil. Therefore, it is important to produce high quality fecal soil by removing impurities and earthworms.

Therefore, the present invention has been proposed to solve the above problems, the object of the present invention is to automate the selection of earthworms and feces soil by-products generated after treatment in organic waste treatment technology using earthworms and earthworms and high quality Fecal soil can be sorted, facility investment cost and operation maintenance cost is low due to the simplicity of the facility, and to provide for easy repair and repair in the event of a failure of the facility.

1 is a processing system showing a process for sorting using the earthworm fecal soil automatic sorting device according to the present invention.

Figure 2 is a schematic diagram showing the earthworm feces automatic screening device according to the present proposal.

3 is a screening principle of the earthworm feces automatic screening device shown in FIG.

4 is a state in which the stool sorting screen is connected to the earthworm sorting pin shown in FIG.

In order to achieve the above object, the present invention will be described in detail with reference to the accompanying drawings.

Earthworm, fecal soil and overs mixed materials are connected to the motor (Fig. 2-⑦) by using a conveyor belt (Fig. 2-①) or by manpower or by using a protective device such as a shovel, fork crane, or ski loader. Rotary earthworms are fed into the fecal sorter. The injected mixture is inclined at an angle of 1 to 5 ° and is moved toward the outlet by gravity in the rotating inside of the dream (Fig. 2).

The earthworm in the mixed mixture is an earthworm sorting pin (length 30mm ~ 150mm, connected to the fecal sorting screen (Fig. 3-⑧), 3 to 10) to fall to the sorting, earthworm sorting BOX (Fig. 3-⑤). The earthworms included in the mixture are caught by the rotating earthworm sorting pin, and the earthworms caught on the sorting pin rotate and fall down by gravity from the top of the earthworm sorting box and fall off to the earthworm sorting box.

Fecal soil and overs are selected by the fecal soil screen. Fecal soil sorting screen (Fig. 4) is made of 2.5mm perforated network so that fecal soil having an average particle size of 2mm is discharged and sorted between the perforations, and overs having a size of 2.5mm or more are discharged and sorted without passing through the perforations.

Fecal soils selected by 2.5 mm perforations include pure feces as well as overs having a smaller diameter than feces. After passing through the 2.5mm perforated material, the pure fecal soil and fine overs are separated and separated through the screen for fine material having 1.5mm perforated.

The earthworm fecal soil sorter according to the present invention can solve the problems of low work efficiency and fecal soil quality of the existing sorting method, and has the advantages of low initial installation cost and easy maintenance, maintenance and management compared to the existing sorter.
