Description

[Detailed description of the invention] Generally, in order to dry livestock manure such as cow manure, pig manure, chicken manure, etc. in a fermentation tank, the manure is deposited in a mountain shape in the input section provided at one end of the fermentation tank, and the accumulated manure is By repeating the process of scraping off livestock manure with a scraping chain device installed on a trolley, transporting it backwards and dropping it, and depositing it in a mountain shape again, the agitation effect of the livestock manure during scraping is promoted and aerobic conditions are created. Drying is performed by fermentation.

This type of stirring and conveying device in the past involves penetrating the tip of the scraping cheno device into the bottom of the mountain-shaped accumulation of animal manure, and in this state, moving the trolley to scrape up the livestock manure with the chino device. It is designed to be dropped from the rear end of the

If this is done, the tip of the cheno device will penetrate into the bottom of the pile of livestock manure, which will put an excessive load on the trolley and the cheno device, and in order to counter this, the structure of each part must be strengthened. In addition, the entire device becomes large and requires a lot of effort to maintain and manage.
It has the disadvantage of being disadvantageous in terms of cost.

Furthermore, there was also a device that used a crushing blade to scrape up and transport the sediment upward along an inclined surface, but this device was not suitable for scraping up easily crumbled deposits of livestock manure, and neither of the above devices Even if there were, the equipment had to be moved and operated within the fermenter in which animal manure had been deposited, so space for movement had to be secured within the fermenter, making it impossible to use the inside of the fermenter effectively. Ta.

The present invention was developed in view of this point, and when scraping up piles of animal dung, the Cheno device is configured to scrape along the inclination direction of the piled up animal dung. The purpose is to reduce the required power and simplify the structure while ensuring reliable agitation and conveyance.

The present invention will be explained below based on embodiments shown in the drawings.

1 is a livestock manure fermentation tank partitioned on both sides by side walls 2, 2;
One end serves as an input section 3 for livestock manure, and the other end serves as a take-out section 4.

Reference numeral 5 denotes a running trolley installed on the fermenter 1, which runs on rails 6 and 6 installed on the side walls 2, 2 and reciprocates along the longitudinal direction of the fermenter 1.

7 is its running wheels, 8 is a running electric motor, and 3 is a speed reducer.

Reference numeral 10 denotes a scraping chino device that is supported on the traveling trolley 5 so as to be able to rise and lower;
A scraping plate 10'' made of an angle-shaped member is installed horizontally between a pair of endless rotary chinos 1010'.

Reference numeral 11 denotes a supporting frame of the chino device 10 which is framed in a substantially triangular shape, and whose base end corner portion is pivoted 13 to the traveling trolley 5 by a drive shaft 12, and a drive sprocket 14 is provided on the drive shaft 12. Sprocket at the tip corner and bottom corner) 15.16 is provided and the same sprocket) 1
The endless rotary chino 10' is hung between 4, 15 and 16.

Reference numeral 17 is a driving motor for the chenette device 10 provided on the traveling carriage 5.

Reference numeral 18 denotes an elevating device for the chino device 10, in which a sprocket 19 is provided at the top of the front end of the traveling carriage 5, and one end of the towing chino 20, which is wound around the sprocket 19, is fixed to the front end of the support frame 11, and A wire rope 21 is connected to the other end of the chain 20, and the wire rope 21 is wound up and unwound by a winding drum 22, thereby raising and lowering the chain device 10 around a pivot point 13 by a drive shaft 12. It is.

24 is an electric motor for winding. And the lifting device 1
8, the chain device 10 is lowered into the fermenter 1 (the state shown by the solid line in FIG. 1), the lower transition part of the chain device 10 is formed into a substantially ■-shaped transition part, and A downward transition slope portion 10a is provided on the rear side, and an upward transition slope portion 10b is provided on the other rear side.

Reference numeral 25 denotes a plate that faces the lower side of the upward transition slope portion 10b, and has both ends raised upward, and the raised portions serve as guide sides for the endless rotating chinos 10', 10'. There is.

The reference numeral 26 in the figure is a spring that elastically supports the sprocket 16 located in the trough of the substantially ■-shaped transition portion. The sprocket 16 is supported so as to be movable up and down, and the upper surface of the mounting plate 27 is pressed by a spring 26 to urge the sprocket 16 downward.

Therefore, the livestock manure discharged from the livestock barn is transferred to the input section 3 of the fermentation tank 1.
They are deposited in a mountain shape and are sequentially dried. During this drying process, the Cheno device 10 is lowered into the fermenter 1 as shown in FIG.
The traveling carriage 5 is moved (in the direction of the arrow a) with the downward moving inclined portion 10a of 0 facing the front.

Then, due to the movement of the truck 5, the downward movement slope part 10
When a comes into contact with the accumulated livestock manure, the livestock manure is gradually scraped down, and this scraped down livestock manure is scraped up by the inclined portion 10b, which moves upward on the plate 25, and the receiver moves upward on the plate 25. The animal dung falls one after another and is deposited in a mountain shape again at the rear of the chenette device 10, and the animal dung is stirred and conveyed during this scraping down and scraping up.

In this case, since the downward transition slope portion 10a scrapes down the livestock manure piled up in a mountain shape along the inclination direction, the scraping operation can be performed under a light load.

Moreover, since the cutting operation is performed by scraping down, even deposits of animal manure that are easily crumbled can be transported efficiently.

There are lumps in the livestock feces and the upward transition slope 10 b
If there is a problem in intervening between the sprocket 16 and the plate 25, the elastically supported sprocket 16 rises against the spring 26, expanding the intervening gap, and due to the elasticity of the spring 26, it becomes endless. The rotating ceno 10' is freely bendable, and the interval between the plates 25 of the upwardly inclined part 10b can be changed as appropriate, so even large lumps can be transported, and the elasticity of the spring 26 Since the lumps are conveyed while being pressed against the plate 25 by the returning force, the lumps are crushed and crushed within the above-mentioned interval.

When the agitation and conveyance of livestock feces by the chenost device 10 while moving the traveling trolley 5 as described above is completed, the chenost device 10 is raised by the elevating device 18, and in this state, the traveling trolley 5 is moved backward (in the direction indicated by the arrow). then fermenter 1
After new livestock manure is deposited in the input section 3 of the fermenter, the Cheno device 10 is lowered into the fermentation tank 1, and the livestock manure is stirred and conveyed in the same manner as described above.

Therefore, in the fermentation tank 1, the livestock manure is transported from the input section 3 to the take-out section 4 while repeating stirring and transport for each pile several times.

Since the present invention is constructed as described above, the scraping chain device can scrape down livestock manure under an extremely light load, and unlike conventional methods, it does not require a strong structure to withstand excessive loads. First, it has the excellent effect of allowing reliable and smooth stirring and conveying work to be performed while simplifying the structure.

In addition, since the equipment can be moved above the fermenter, the space inside the fermenter can be used effectively, and since the cutting operation is performed by scraping down, even easily crumbled deposits of animal manure can be transported efficiently. Yes, due to the action of the spring 26,
It has the effect that even large lumps can be transported while being crushed.
