Description

[Detailed Description of the Invention] The present invention relates to a manure separation device that automatically separates excreted manure into manure and urine on a livestock rearing floor or in a manure groove.

It is well known that post-processing of manure excreted during rearing can be achieved smoothly by promptly separating solid-liquid.

Conventionally, in the case of tied barns mainly used for raising dairy cows, the rear part of the cow bed is slightly sloped to form a urine groove, and the excrement excreted in the middle of the slope is manually removed with a scoop, etc. Either the manure can be separated by letting it flow into the lower part and be discharged, or a manure groove with a rectangular or reversely convex cross section can be formed at the rear of the cow bed, and a porous partition wall can be installed at an appropriate height inside the manure groove. Then, the upper part of the porous partition wall is used as a feces transport path, and the lower part is used as a urine flow path to automatically separate feces and urine. As soon as the urine is transported to a location, it is discharged through the urinary tract and separated from the urine.

In addition, there is a so-called gravity flow method for treating manure and urine, which is often seen in dairy cow breeding, and this method is
A 100cm manure groove is installed at the rear of the cow bed at a position where the hind legs can be covered, and a steel or other rostrum is installed in this to allow all excreted manure to fall into the manure groove and be stored there. It decomposes and liquefies it.

There is also a method of raising beef cattle and fattening pigs in which a large amount of bedding is placed on the breeding bed and the manure mixed with the bedding is discharged at a timely manner without separating the manure. In addition, some beef barns and fattening pig barns have all or part of the rearing floor as a screen bed, and the manure is dropped below the screen, and the manure and urine are separated and discharged on the sloped floor below the screen.

Furthermore, egg-laying hens are overwhelmingly kept in cages, and fattening pigs are also kept in cages. Chicken manure that falls under the cage is directly removed, and pig manure is separated and discharged using a sloped floor or perforated belt. It is something to do.

By the way, in the above-mentioned devices of the gravity flow type in which manure and urine are not separated, the manure is completely mixed, so a large field is required for the spraying treatment.

With porous partition plates and perforated belts that separate excrement, automatic separation of urine cannot be achieved accurately due to clogging of the holes, and methods using sloped beds are extremely difficult to separate excrement because urine gets on the excrement. Complete.

The method of laying a large amount of bedding on the rearing floor to absorb and discharge excreta has become difficult due to the recent shortage of bedding. Even in the case of cage rearing, some urine is mixed with the feces, so separation of feces and urine is not always complete. Due to the above-mentioned reasons, all conventional methods have the drawback of not being able to accurately process excrement and urine, and there has been a strong desire to improve this problem.

In Utility Model Application Publication No. 55-14420, the present applicant has developed a system in which feces are left in the lower part of a feces and urine groove provided on the rearing floor surface, forming a urine separation filter bed that filters only urine, so that feces and urine are separated at any time. To provide an excrement and excrement separation device in a excrement ditch, which can achieve automatic separation of excrement and excrement and efficiently carry out excrement processing work. However, this method has the disadvantage that it is difficult to repair the filter when it becomes clogged, and it is difficult to repair the filter when it becomes clogged. It had drawbacks such as difficulty in attaching it to the top.

Therefore, in view of the above, this invention was developed in 14420.
The model has been further improved, and it has the same good separation of manure and urine as the above, and can be installed not only on manure and urine grooves, but also on wide breeding beds and cages, and when clogging occurs. The purpose is to provide a means for easy repair, and the configuration of the device of the present invention will be explained below based on various embodiments.

Figure 1 is a schematic diagram of a part of a barn cleaner used for transporting manure and urine from a dairy cow shed, and 1 is a rearing floor surface on which dairy cows can be reared while being tethered. A excrement groove 2 having a depth of . FIG. 2 is a sectional view of the excrement groove 2, and 3 is a support on which the excrement conveying plate 10 slides. Reference numeral 4 is a urinary tract, which is a flow path through which only urine of the excrement and urine dropped onto the filter medium 9 is filtered and discharged. 6 is a corrosion-resistant perforated iron plate, 7 is a corrosion-resistant wire mesh or plastic filter cloth, 8 is a corrosion-resistant steel grating or expanded metal, and 9 is a filter material such as rice hulls, sawdust, crushed straw, pumice, sand, etc. be. Note that 5 is a concrete support part that supports 6, 7, 8, and 9, and 11 is a work passage. Reference numeral 10 denotes a feces conveying plate, which is attached to a chain 13 of a conveying body 12 that rotates within the excrement groove 2, as shown in FIG. Of the excrement and urine dropped onto the filter medium 9, the urine is filtered and discharged into the urinary tract 4, thereby ensuring separation of the excrement and urine.
The feces left on the filter medium are transported to a predetermined location by the transport plate 10. In addition, since it has 8 gratings or expanded metal, livestock hooves will not get stuck in it and cause any damage. Furthermore, although part of the filter medium 9 and excrement are removed by the conveyor plate 10, complete excrement and urine separation can be performed again by simply replenishing a small amount of the removed filter medium.

Furthermore, the second embodiment of the apparatus shown in FIG. A suction fan 14 for suction, a conduit 15 thereof, and a cover 16 to prevent filtered urine from entering the conduit 15 are attached, and
In this embodiment, to remove the feces on the filter medium 9, an input such as a scoop or other removal machine is used. Furthermore, although the suction fan 14 is installed on the aisle or outside the livestock barn, it can be installed in the same manner in the first, third, fourth, fifth, etc. embodiments to further improve the separation of feces and urine. It is possible to improve the condition and is effective.

The device of the third embodiment shown in FIG.
This is an example of a feces and urine separator disposed on top of the feedstock, and can also be disposed on the rearing floor of a cage for beef cattle.

The device of the fourth embodiment shown in FIG.
is a conventionally used steel rostol.

The embodiment shown in FIG. 6 is a feces and urine separator installed at the bottom of a pig cage, and 18 is a cage provided in the cage, from which the feces and urine are separated into 6, 7, 8, Feces and urine are separated by a feces and urine separator comprising 9. Incidentally, the excrement and urine separator installed at the bottom of the pig cage can also be made horizontal or sloped to near-horizontal, as in other cases, and it is possible to run the manure remover on top of it.

The embodiment shown in FIG. 7 is an example in which the device is installed at the bottom of a chicken cage, where 19 is a cage, 20 is a feed trough, and 21 is a drinking water trough. The height of the working passage 11 is suitably adjusted to facilitate the working.

Although not shown, as described above, it is of course possible to connect the suction conduit 15 to the suction fan 14 to completely remove moisture.

Next, the operation of the present invention will be explained with reference to a first embodiment.

Now, if dairy cows or beef cattle are raised in a tethered state on the breeding floor 1, the excrement and urine excreted during the breeding will fall into the manure groove 2. Since a filter medium 9 is laid in the excrement groove 2, the excrement remains thereon, and only the urine is filtered and flows into the urinary tract 4 to be discharged. Therefore, if the chain 13 is rotated in the direction of the arrow, the many conveyor plates 10 will also move in the direction of the arrow,
The remaining feces are transported along the excrement groove 2 for treatment. In addition, in the process of being conveyed by the conveyor 12 as described above, only a part of the sawdust, etc. laid at the top position of the filter medium 9 is conveyed, so there is no need to worry about clogging or the like. This makes it possible to improve the urine filtration effect and to discharge urine without fecal solids along the urinary tract 4. Furthermore, compared to Utility Model Publication No. 14420/1983, the addition of grating 8 prevents livestock hooves from getting stuck in the grooves, and prevents the upper filter medium from clogging due to long-term use. Even so, it is extremely easy to repair by replacing the upper filter medium, and it has the advantage that the amount of new filter medium to be laid on the upper part each time is kept to an extremely small amount each time feces are removed.

The present invention can be installed on the floor of a livestock barn, so construction is not only easy and inexpensive, but also, as shown in the second embodiment, by connecting a suction fan to the urinary tract 4, it can be installed on the filter medium 9. Since the remaining feces is dehydrated and dried, post-processing of the removed feces becomes extremely easy.

Furthermore, as shown in the third embodiment and the following, it can be placed in the upper part of the cage in a cage for livestock or in the lower part of the cage to separate manure and urine, and to dehydrate and dry the manure, which has the advantage of having an extremely wide range of uses.

In short, the present invention sequentially stacks corrosion-resistant perforated iron plates, corrosion-resistant wire mesh or plastic filter cloth, and corrosion-resistant steel grating or expanded metal on the upper surface of the floor of the livestock barn or the upper surface of the manure ditch.
On top of that, filter media such as rice hulls, sawdust, crushed straw, pumice, sand, etc. are layered to form a urine separation filter bed that only filters urine. In addition to making post-processing easier by reducing the water content of the feces and making it easier to carry out post-processing, even if the filter bed becomes clogged, it is extremely easy to repair by replacing only the upper filter material. Moreover, it is effective and can be applied to any livestock barn without damaging the livestock's hooves.
