Description

[Detailed Description of the Invention] The present invention relates to a raking conveyor device in a compost ripening device.

A compost aging device stores compost made from a mixture of chicken, pig, etc. manure, wood chips, sawdust, etc. in a fermentation tank, ferments and matures it with aerobic bacteria for a certain period of time, and then scrapes it off. It is equipped with a scraping conveyor that transports the water to the outside of the tank.

The raking conveyor is mounted on a cart installed over the fermenter, and while the cart is running, the raking conveyor is tilted downward, and its lower end is pressed against the compost in the fermenter to scrape it off. However, whereas compost is spread over the entire surface of the fermenter, a gap is formed between the scraping conveyor and the inner wall of the fermenter, and the compost on both sides of the conveyor cannot be scraped away. There is a problem in that the compost is wasted, and since the compost is viscous, it hardens under the lateral pressure of the raking conveyor, giving excessive resistance to the raking conveyor while the cart is running.

This proposal solves the above problem. Impellers are installed on the outer surface of the base frame on both sides of the lower end of the raking conveyor, and while these impellers are continuously rotated, the compost in the fermenter is raked up onto the raking conveyor, and the compost on both sides of the conveyor is The compost is characterized by being broken down by an impeller to facilitate the scraping and conveyance of the compost by a scraping conveyor.

Examples of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the compost ripening device includes a long compost fermentation tank 1, a trolley 2 installed on top of the tank 1 so as to be able to travel across it, and a rack installed on the trolley 2. It consists of a lifting conveyor 3, a conveyor 4, and a take-out conveyor 5 movably installed at the base end of the fermenter 1.

The scraping conveyor 3 has support shafts 6X, 6 at both ends of the base frame 3a.
X is equipped with wheels 6A, 6A... and 6B, 6B... respectively, an endless chain 7 is passed between both wheels 6A, 6B, and a belt 8 is laid along the chain 7. , scraping bars 9, 9°, etc. are attached to the links of the chain 7 at regular intervals, and both base frames 3A, 3A are pivoted to the trolley 2 via a shaft 10 so as to be movable up and down, and the trolley A rope 12 of a winch 11 installed on the base frame 3A is tied to a part of the upper edge of the base frame 3A.

The support shafts 6X of the wheels 6A, 6A are made to protrude from both sides of the lower end of the base frames 3A, 3A in this scraping conveyor 3,
Impellers 13, 13 are attached to the projecting ends of the shaft 6X, respectively.

In the figure, reference numeral 14 denotes a drive motor for the scraping conveyor 3, which is linked to one wheel 6B via a series of pulleys and a belt, and the drive of the motor 14 gives continuous feed in one direction to the chains 7, 7. , the impeller 13.13 is rotated at the same time.

Note that the impeller 13 has radial bars 13A, 13A, . . . that project outward from at least the tip of the scraping bar 9.

In fermenter 1, excrement from chickens, pigs, etc., wood chips,
When compost made from a mixture with sawdust etc. is fermented and matured for a certain period of time with aerobic bacteria and then transported, the rope 12 of the winch 11 is loosened and the raking conveyor 3 is placed in a forward downward tilted position. This is inserted into the tank 1, the motor 14 is started, and the chain 7.7 is continuously fed in one direction, so that the cart 2 is moved along the tank 1.

As a result, the scraping bar 9 scrapes a portion of the compost onto the conveyor 3 at the tip of the scraping conveyor 3, and sends it onto the carry-out conveyor 4.

On the other hand, the compost in the gap d on both sides of the base frames 3A, 3A is not scraped onto the conveyor 3, but in the base frame 3A.

The impellers 13 located on both outsides of the fermenter 3A rotate together with the wheel 6A, crush the compost piled up along the inner wall of the fermenter 1, break up the pile, and move it towards the center of the fermenter 1. send

Every time the compost fed onto the carry-out conveyor 4 reaches a fixed amount, the scraping conveyor 3 is pulled up, the cart 2 is moved backward, and the compost is taken out and sent to the conveyor 5 to be carried outside.

This process is repeated to take out the entire amount of compost in the fermenter 1 to the outside, but at each step, the pile of compost that has been filled along the inner wall of the fermenter 1 that cannot be scraped is transferred onto the scraping conveyor 3. is crushed toward the center by the impeller 13, and scraped onto the scraping conveyor 3 in the next step.

As mentioned above, the main frame of the scraping conveyor 3 is 3A, 3A.
Impellers 13 and 13 are provided on both outer sides of the impeller 3A,
3A is rotated, the compost on both sides of the conveyor that cannot be scraped off by the scraping conveyor 3 is broken up in each process and moved toward the center, and can be easily scraped and carried out in the next process. The entire amount can be taken out without leaving any compost on either side.

Moreover, according to the present invention, since the impeller 13 breaks up the compost on both sides of the conveyor in each process, the raking conveyor 3 does not receive excessive resistance as in the past, and the trolley 2 moves smoothly to carry out the compost removal work. This has the effect that it can be carried out without difficulty.
