BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cow dung separation / removal device.

[0002]

2. Description of the Related Art A conventional manure is equipped with a manure removing device for scraping a mixture of manure collected in a manure accumulating pit to the outside of the front end of the pit by the left and right scrapers of the scraper device. There is.

[0003]

According to the above-mentioned conventional apparatus, since the manure and urine are removed together, it is necessary to separate the manure and urine mixture into manure and urine for the production of compost thereafter. A large area, equipment and work are inevitable. Therefore, since the manufacturing cost of the compost increases, it is desirable to eliminate such occupied area, equipment and work. In addition, since the rope for pulling the scraper device is accommodated in the shallow rope guide groove provided in the central portion of the bottom surface of the pit, the feces and urine removing device easily removes a large amount of feces and removes it. The work is also difficult and brings about the inconvenience of accelerated corrosion. Therefore, it is desirable that the cord is protected as much as possible from the attachment of feces.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the problems of the above-mentioned conventional devices, and provides a manure separation / removal device for cowsheds, which is provided along a bed in a row of cows. In the long sewage accumulation pit provided, a scraper device provided with left and right scrapers supported by a support shaft so as to be able to open legs is provided while being reciprocally run by being pulled by a cord driven by a drive device, A urine groove is formed on the bottom surface of the pit at the center in the width direction and limited by vertical groove walls facing each other in the length direction, and the left and right bottom surfaces of the urine groove are directed toward the urine groove. And a ureter that extends in parallel with the bottom surface of the pit and is connected to the lower end opening of the urine groove, and is hung from the scraper support shaft of the scraper device. Through the urinary cleft A fixed supporting plate extending into the ureter is provided, and a cord connecting rod is provided on the fixed supporting plate so as to extend in a horizontal direction orthogonal to the fixed supporting plate so as to be movable forward and backward by a predetermined distance. A swelling guide passage that can accommodate the rod and the rope connected to both ends thereof and that is parallel to the ureter has a vertical groove wall swelling in the middle of the urinary groove and the bottom surface of the pit. A support plate that is provided in the longitudinal direction in parallel with the cord, and a supporting plate that hangs down from the cord connecting rod and extends into the ureter is provided so as to be movable forward and backward together with the cord connecting rod and that is connected to a lower portion of the movable supporting plate. Is connected to a urine cleaning tool having a diameter capable of being brought into close contact with the inner peripheral surface of the ureter in the ureter, while the support rod connected to the lower end portion of the fixed support plate is used to support the urine cleaning tool via a fulcrum shaft. It is characterized by having supported.

[0005]

The urine released from the manure mixture deposited in the manure depositing pit flows into the urine groove provided in the central portion of the bottom surface by flowing down the left and right inclined bottom surfaces, Collects in the ureter below it. Thus, feces and urine are separated. After that, if the scraper device is pulled in the forward direction by the rope in order to drive the scraper device forward, the cord connecting rod moves in the forward direction, that is, in the forward direction in conjunction with this pulling. At the same time, the movable supporting plate integrated with the cord connecting rod moves forward, and the operating rod connected to this moves forward, thereby pushing the urine cleaning tool and tilting the urine. The cleaning tool rotates about a fulcrum shaft supported by a support rod of the fixed support plate,
You can stand up. From this state, the scraper device is started to move forward by subsequent pulling, and at the same time the left and right scrapers scrape and remove feces in the pit by the running, the urine cleaning device in the standing state is
Sliding in the ureter and extruding and removing urine containing mud-like sludge without leaking backward. Thus, after the defecation and urine removal is completed, the defecation machine is pulled by the cord in the direction opposite to the front, that is, when it is pulled in the forward direction, the cord connecting rod interlocks with this,
In the return direction, that is, in the backward direction, the movable support plate integrated therewith causes the operating rod connected thereto to move backward, whereby the urine cleaning tool is pulled and the urine cleaning tool is the fulcrum. Tilt around the axis. Due to the subsequent pulling, the scraper device starts the backward traveling. The left and right scrapers of the scraper device are changed from the open leg state to the closed leg state during the backward traveling by the inclined bottom surfaces on both sides thereof. On the other hand, since the urine cleaning device moves backward in a tilted state away from the inner peripheral surface of the ureter, that is, in an inoperative state in which the urine removing work is not performed, abrasion of the urine cleaning device is avoided.

The forward and backward movement of the rope connecting rod with respect to the fixed supporting plate by a predetermined distance causes the rope connecting rod to be orthogonal to the fixed supporting plate, and through the long hole and the engaging pin inserted through the long hole, It is preferably obtained by linking. As a result, the fixed support plate can be formed so thin as to penetrate the narrow urine groove, and the cord connecting rod can be housed in the guide passage that is bulged in the middle of the urine groove. .

When the width of the urinary groove is limited to about 12 mm at the maximum, when a cow walks on the bottom surface of the pit, hoofs are prevented from entering the urinary groove and damage such as sprains and bone fractures occurs. In addition, it is possible to prevent feces from falling into the urinary ditch and sticking to them as much as possible.

Further, the opposing groove wall defining the urine groove and the guide passage bulging in the middle thereof and the ureter are integrally formed by extrusion molding of a metal material or drawing of a single metal plate. When forming on the molding frame, set it at a predetermined position and pour concrete on its outer periphery so that the pit with the urine groove, the guide channel and the ureter at the center can be raised all at once. It can be constructed efficiently and inexpensively.

In the above-mentioned operation of the device of the present invention, during forward traveling of the scraper device, the scrapers on the left and right of the scraper float up at the portion raised by the feces and straw scraps stuck to the bottom surface of the pit, and this rise There is a dislike that the part cannot be scraped off, and also that the urine cleaning tool moves upward due to the lift and is pressed against the upper surface of the inner peripheral surface of the ureter, which hinders the forward movement of the scraper device. In order to eliminate such inconvenience, according to the present invention, the scraper device is configured as follows. That is, the scraper device has the fixed support plate at the lower end of the support shaft, a pair of left and right scrapers is provided on the outer peripheral surface of the support shaft so as to be able to open legs, and a shoe member provided at the tip of the left and right scrapers is provided. The wheels are attached to the outer surface, and the left and right wheels are attached to the left and right facing vertical side wall surfaces of the manure accumulation pit,
When the scraper device is configured to be insertable in the fitting groove provided in the length direction in parallel with the floor surface, the wheels at the tips of the left and right scrapers respectively move during forward movement of the scraper device. The scraper device is inserted into the fitting groove provided on the vertical side wall surface of the pit and rolls to assist the smooth running of the scraper device, and the wheel is always engaged with the fitting groove to suppress the lifting. The urine cleaning tool in the standing state inside the ureter does not lift up during running and prevents the buildup of dung and straw waste that sticks from the beginning. The movement of the scraper device can be maintained and the running of the scraper device is not hindered. Thus, good cleaning of feces and urine can be performed.

[0010]

Embodiments of the present invention will now be described with reference to the accompanying drawings. FIG. 1 is a schematic plan view of an in-house cow excrement separating and removing apparatus according to an embodiment of the present invention. In the lengthwise direction, a row of beef stalls separated by fences (not shown) in the drawing is provided in the lengthwise direction. 2 shows two wide pits 2, 2 having a U-shaped cross section, which are provided along the line. Although not shown, the manure accumulation layer pit 2 is a raised bed 1 for bed.
It goes without saying that it may be formed between 1 and 1.

Reference numeral 3 denotes a scraper device having a pair of left and right scrapers arranged at the positions shown by the solid lines at the rear end of one pit 2 and the front end of the other pit 2 so as to be able to open legs. Each of the scraper devices 3 and 3 is arranged so that reciprocating motion is alternately performed via the cord 5 to the drive device 4 installed at the center in the width direction at one end in the length direction of the floor in the barn. I chose The drive unit 4 may be of any known type, but preferably, as shown in the figure, the drive unit previously disclosed by the applicant in Japanese Patent Application No. 6-200069 is used. That is, the pair of left and right take-up drums 4 connected to the reversible motor 4a of the drive device 4 via the clutch mechanism 4b.
The cords 5 are alternately wound around and unwound on c and 4d. The rear end sides of the respective scraper devices 3 and 3 are connected to each other by an intermediate cord 5. Thus, one of the winding drums 4c or 4d is rotated by the reversible motor 4a of the drive device 4 so as to perform the winding operation, and the winding of the rope 5 winds the winding drum 4c or 4c on the other winding drum 4c or 4c. When the taken rope 5 is driven so as to be unwound along with this winding, one scraper device 3 travels forward in the forward direction, and the other scraper device 3 moves in the backward direction. I made it possible to run backwards. In order to alternately repeat the reciprocating motions of the scraper devices 3 and 3, of course, a conventionally known drive device, that is, a device in which the intermediate portion of the cord is wound around the guide groove on the outer periphery of the drive drum is used. It can also be used. In the illustrated embodiment, the left and right pits 2 and 2 have different widths, but instead, the pits 2 and 2 have the same width and are reciprocated in the respective pits by a scraper device having the same size. Needless to say, the design may be changed so that the vehicle runs.

As shown in FIG. 2, the bottom surface 2a of each of the pits 2 has a center portion in the width direction thereof, preferably, the left and right bottom surfaces of the center portion of the pit 2 on the basis of the center axis, which is 2/10 to 10/100.
While making the inclined bottom surfaces 2a, 2a having a gradient of about 0/3,
The scraper device 3 includes a support shaft 3a, a pair of left and right long scrapers 3b, 3b mounted on the support shaft 3a, bearings 3c,
It is attached so that the legs can be freely opened and centered through 3c. In the drawing, 3d is a bush, 3e is a washer, and 3f is a stop bolt. The scraper device 3 opens its legs by friction with the inclined bottom surfaces 2a, 2a as it moves forward in its forward travel, and the shoes 3g, 3g at the tips of the left and right scraper main bodies 3, 3 are opened in the maximum open legs. , The left and right vertical side wall surfaces 2b, 2b of the pit 2 are struck and slidably contacted, and the corresponding left and right inclined bottom surfaces 2a, 2a are slid over the entire surface thereof, and the accumulated feces are scraped off as they advance. Then, it is scraped out to the front of the dung removal groove 6 for cleaning.
In the return travel, the inclined bottom surfaces 2a, 2a cause the left and right scrapers 3b, 3b to be closed by themselves in accordance with the subsequent travel, so that the backward movement is smoothly performed and the scraper 3b, 3b is originally in an inoperative state. I tried to return to the position. The defecation groove 6 is provided adjacent to the front ends of the left and right pits 2, 2 and is provided in common at right angles. A screw conveyor 7 is provided therein, and the screw conveyor 7 is driven by an external drive motor (not shown). The dung in the dung removal groove 6 that has been driven and scraped out by the scraper device 3 is transferred to the dung collecting tank outside the livestock shed. Reference numeral 8 denotes a long rectangular shape that straddles the opening on the upper surface of the fecal excretion groove 6 and is placed in step grooves on both side edges thereof so that the upper surface is at the same icicle position as the left and right inclined bottom surfaces 2a, 2a. Showing the sludge and thus the scraper device 3
Was exposed to the upper surface of the sludge 8 so that the scraped feces could be surely dropped and removed into the sludge removing groove 6. 9 in the drawing
Is a corner pulley, 10 is a switch control panel whose outer end is connected to an external power source, 11 is a reversing limit switch, 1
2 is a limit switch for stopping, 13 is a feed tank, and 14 is a working passage.

A scraper device 3 is provided in the pit 2 described above.
In the device provided with, the scraper device 3 is reciprocally traveled by being pulled by the rope 5, which is no different from the conventional device. According to this, since the excrement mixture excreted in the pit 2 is scratched out to the defecation groove 6, the excreted excrement mixture has no water content until this time, as described above. It is uneconomical and inefficient because it is excessive and not suitable as a raw material for compost production, and after that, separation work of feces and urine is required. Further, although not shown, the conventional cord uses a link chain, and since it is accommodated and guided in a wide groove which is wide enough to accommodate the link chain provided at the center of the bottom surface of the pit, There was a dislike that accumulated manure sludge entered the groove and a large amount of feces adhered to the chain to promote contamination and corrosion.

In order to eliminate such inconvenience, the present invention provides
In order to improve the conventional manure removal device, we have developed a device that enables simultaneous separation and removal of manure in the work and prevention of contamination of cords as much as possible. I will describe. That is, in the illustrated embodiment, the same device of the present invention is provided in each of the left and right pits.
Since the configuration and the function and effect are the same, only one of them will be described below. A narrow and deep urine groove 15 is provided over the entire length of the bottom portion 2a of the pit 2 in the widthwise central portion, generally preferably on the central axis thereof. More specifically, the urine groove 15 is formed by a pair of left and right vertical groove walls 15a, 15a that form a limited width of the urine groove 15. Preferably, as will be described later, the pit 2 is provided so as to extend outward beyond the above-mentioned defecation groove 6 at the front end thereof. The width of the urine groove 15 is the bottom surface 2 of the pit 2.
When cows walk a and 2a, it is preferable that the cowl has a narrow width so that even a part of the hoof does not enter the urinary groove 15 and an accident such as a sprain or a fall does not occur. When I examined this, maximum 12
It has been found that a groove width of up to about 13 mm, specifically, up to 13 mm is acceptable. Generally, the groove width is about 9 to 11 mm. In addition, this narrow width has an advantage that feces are less likely to fall into the urine groove 15 and, as will be described later, contamination of cords can be prevented as much as possible. In connection with this, as the cord 5, a groove wide enough to accommodate the ring chain is not preferable. Generally 8-10 mm with a diameter of 11 mm or less
It is preferable to use a wire having a diameter.

The cord 5 made of the wire is attached to the support shaft 3a of the scraper device 3 by welding or the like on the lower end face thereof, hangs down from the support shaft 3a, and penetrates the urine groove 15 to extend downwardly from 8 to 10 mm. A thick and thin corrosion-resistant metal fixed support plate 16 is provided, and a long line-shaped long line plate-like long line-shaped long line connection part 17 is provided at right angles to the fixed support plate 16. The parts 17a and 17a are connected.
The cord connecting portion 17 is made of a corrosion-resistant steel plate or the like, and is provided at the middle portion of the urine groove 15 with the left and right vertical groove walls 15a,
The opposite bulging wall 15 that is wider than the urine groove 15 formed by bulging outward 15a, and bulges in an arc shape in the illustrated example.
It is accommodated in a long guide passage 18 which is defined by b and 15b, and inside the guide passage 18, the scraper device 3
I was able to run with the reciprocating motion of. The rope 5 was connected to the rope connecting portions 17a, 17a at both ends of the rope attaching plate portion 17 as follows. That is, each rope attachment plate portion 1
Reference numeral 7a denotes a thin mounting arm plate that slightly protrudes above the floor surface 2a beyond the urine groove 15, a notch 17b is provided in the middle of each protruding end thereof, and a bracket 17c orthogonal to the protruding end. Then, one end of the wire 5 which is passed through the upper surface of the bracket 17c from below into an insertion hole 17d provided at the outer end of the bracket 17c is connected to the bracket 17c by a U-bolt connector 19 through the cutout portion 17b. The rope 5 was connected. Thus, the front and rear cords 5, 5 connected to both ends of the cord connecting member 17 have the cord attaching plate portions 17a, 1
In the vicinity of 7a, it is exposed to the outside from the floor surface 2a, but as it gets farther, it hangs down in the urinary groove 15 due to its own weight, penetrates deeply into the urinary groove 15, and is far from the feces on the floor surface 2a. In this state, the urine groove 15 and the guide passage 18 are guided in this state to move forward or backward. In FIG. 1, for convenience, the cord 5 in the urine groove 15 is shown to be visible over the entire length, but the cord 5 has a bottom surface on the side connected to the winding drums 4c and 4d of the drive unit 4. , The cord 5
It is preferable to make a concave groove for guiding. In addition, the urine groove 15 is connected at a level substantially the same as that of the guide passage 18 by the corner pulleys 9 and 9 via pulleys that guide the winding drums 4c and 4d to near the winding drums 4c and 4d, or a driving device. It is preferable that the bottom surface of the cord 4 is dug down to be installed until the cord 4 is at substantially the same level as the cord 5.

Further, according to the present invention, the ureter 2 is opened and communicated with the lower end of the urine groove 15 and parallel to the bottom surface 2a of the pit 2.
0 is provided, and the lower portion of the fixed support plate 16 that hangs down from the support shaft 3a faces the ureter 20. In the illustrated example, the lower part of the ureter 20 is positioned on the central axis of the ureter 20 up to about half of the inner diameter of the ureter 20. In the forward direction of the scraper device, that is, the base end of a long plate-shaped support rod 21 extending to the right in the drawing is connected, and a flat plate, a dish-shaped plate, A urine cleaning tool 22 having an arbitrary shape such as a hemispherical plate was connected. The urine cleaner 22 is
The outer peripheral edge has a diameter that is in sliding contact with the inner peripheral surface of the ureter 20 having a circular cross section. In the drawing, the urine cleaning tool 22 is mainly composed of a flexible elastic plate 22a made of rubber having the above diameter,
From the front and back, this is a metal holding plate 22 with a diameter slightly smaller than this.
Binder 22d sandwiched between b and 22c and composed of bolts and nuts
Then, these superposed plates 22a, 22b, 22c are bonded to each other and integrally formed. In the illustrated example, the support rod 21 is composed of two left and right rear long plates 21a and 21a which are connected to each other by a bolt nut 23 and one front long plate 21b. Rear long plates 21a, 21
a is fixed to both side surfaces of the fixed support plate 16 by welding, and a front end of a front long plate 21b thereof is projectingly provided at the center of the restraining plate 22c of the urine cleaning tool 22. It was connected to the connecting shaft 25 supported by and was supported.

The bulging walls 15b, 15b are formed in the middle of the urine groove 15 and the bulging guide passage 18 in the middle thereof.
The left and right vertical groove walls 15a, 15a and the ureter 20 opening on the lower surface of the left and right vertical groove walls 15a and 15a are preliminarily cross-sectioned by extruding a metal material by an extruder or drawing a single metal plate. It is preferable to produce the gourd-shaped elongated groove frame-shaped integrally molded frame A. Thereby, when constructing the floor surface of the cowshed with concrete, it is set in advance on the foundation ground, and the concrete is poured on the outer periphery of the urine groove, the guide passage, and the ureter in the center with high efficiency and low cost. It is possible to construct the pit 2 that is provided with the inclined bottom surfaces 1a and 1a on the left and right. As is apparent from FIG. 5, the ureters 20 and 20 are fitted from both sides to the sleeve 26 in which the integrally formed frame A is fixedly mounted on the foundation ground G, and the ends are abutted against each other. In the middle of the ureter 20, the upper ends of the left and right fixing frames 28 whose lower ends are fixed to the ground G with anchor bolts 27 are overlapped with the ears 29 protruding from both sides of the upper part of the ureter 20, and the bolt nut is attached. After fixing the integrally-formed frame A with the fixtures 30, the concrete is poured from above to be constructed so that the inclined bottom surfaces 2a, 2a are formed to a predetermined thickness and on the left and right sides thereof. Has a body A in the center,
Further, the construction of the pit of the present invention having the inclined bottom surfaces 2a, 2a on the left and right sides thereof is completed. Further, as shown in FIGS. 1 and 11, the integrally molded frame A of the present invention has a urine container 31 which is provided in front of the fecal groove 6 at the front end of the pit 2 so as to straddle the fecal groove 6. It is extended so that it faces inside. The urine bowl 31
As is clear from FIG. 1 and FIG. 9, is open to communicate with an external large-volume urine collecting tank 33 via a urine drainage pipe 32. It is preferable that the urine drainage pipe 32 is provided so as to gradually descend from the urine container 31 toward the urine collecting tank 33, as clearly shown in FIG. Reference numeral 34 denotes a discharge pump, by which the urine collected in the urine collecting tank 33 is fed to an external septic tank, a fermentation tank, or the like.

Thus, in the manure separation / removal device of the present invention described above, the urine released from the manure mixture deposited in the manure accumulation pit 2 flows down centering on the left and right inclined bottom surfaces 2a, 2a, and the The ureter 20 flows into the urinary groove 15 and
Stays inside. Thus, feces and urine are separated. Next, the scraper device 3 is caused to travel forward by pulling the cable 5 driven by the drive device 4 in the forward direction, so that the left and right inclined bottom surfaces 2a, 2a corresponding to the left and right scrapers 3b, 3b. The accumulated pile of feces is scraped off and removed in the fecal groove 6 in front of it. During this time,
The scraper device 3 includes the fixed support plate 16 and a support rod 21 attached to the fixed support plate 16 and the urine cleaning tool 22.
Since the scraper device 3 is moved forward, the urine cleaning tool 22 moves forward and pushes out urine containing mud-like sludge in the ureter 20 to the front and removes it into the urine container 31. The removal of feces and urine is completed at the same time. Urine in the urinal 31 flows down the urinary tract 32,
It is retained in the urine collecting tank 33. The urine in the urine collecting tank 33 is sent to the fermenter or the like by the discharge pump 34.

Next, by the reverse rotation of the reversible motor 4a of the drive unit 4, the scraper unit 3 is moved forward by pulling the rope 5 in the forward direction, and returns to its original position.
In this case, if the urine cleaning tool 22 is retracted in a state of slidingly contacting the inner peripheral surface of the ureter 20, urine is cleaned in the opposite direction of the ureter 20, and the urine container is also provided at the opposite end thereof. Other equipment is required, resulting in an increase in occupied area and equipment cost. In addition, there is a tendency to wear and damage the urine cleaning tool, resulting in a shorter life. In order to eliminate such inconvenience, it is desirable to bring the urine cleaning tool 22 into an inactive tilted state separated from the inner peripheral surface of the ureter 20 during the backward movement. According to the present invention, in the forward travel or the backward travel of the scraper device according to the present invention, first, the urine cleaning tool 22 is erected or tilted in association with the pulling by the rope 5. After that, the scraper device is configured so as to be able to perform forward traveling or backward traveling.

That is, the support shaft 3 of the scraper device 3
Along with the fixed support plate 16 hanging from the lower end of a, the rope connecting rod 17 housed and guided in the guide passage 18 is interlocked with pulling the rope 5 in the forward and backward directions. Then, each is connected so as to move forward and backward by a predetermined distance. In the example shown in FIG. 4, a predetermined length, that is, a predetermined space S
The above-mentioned forward and backward movements can be obtained in the cord connecting rod 17 through the long hole 35 having the above and the engaging pin 36 inserted through the long hole 35. In the illustrated example, as shown in FIGS. 3, 4 and 6, the fixed support plate 16 is provided with the elongated holes 35 in the horizontal direction, and two long holes are formed on both sides of the fixed support plate 16 so as to be orthogonal to each other. With the engagement pin 36 provided on the rope connecting plate 17 made of a scale plate being inserted into the elongated hole 35, the pin 36 contacts the fixed support plate 16 at the front end and the rear end of the elongated hole 35. A predetermined distance corresponding to the space was connected so that the rope connecting rod 17 could move forward and backward. In this way, the cord connecting rod 17 which can be moved forward and backward is hung down from one end, penetrates the urinary groove 15, and penetrates the ureter 20.
A movable supporting plate 37 which can move forward and backward together with the rope connecting rod 17 so as to face the upper space therein, and the rear end portions of a pair of left and right operating rods 38 extending in the horizontal direction are connected to the movable supporting plate 37. The operation rod 38 is connected by a shaft 39, and the tip of the operating rod 38 is fitted and connected by a connecting shaft 41 supported by a shaft support member 40 fixed to the holding plate 22c of the urine cleaning tool 22.

Thus, the cord connecting rod 17 is connected to the cord 5.
When pulling the scraper device 3 in the forward direction and moving it forward, the scraper device 3 does not run immediately, but first of all, the scraper device 3 is interlocked with the scraper device 3 in order to move forward.
7 moves forward by the amount that the engaging pin 36 moves forward from the retracted position of the long hole 35 shown by the two-dot chain line in FIG. 4 to the position shown by the solid line where it abuts against the other end of the long hole 35. That is, the operating rod 38 connected thereto is moved forward, thereby pushing the urine cleaning tool 22 forward, and the urine cleaning tool 22 is erected from the tilted state of the imaginary line with the fulcrum shaft 25 as the fulcrum shaft. It is turned to the side and brought to a standing state in which the peripheral edge thereof is in close contact with the inner peripheral surface of the ureter 20 as indicated by the solid line. Further, since the fixed support plate 16 is pulled forward through the engagement state of the engagement pin 36 and the elongated hole 35 by the subsequent pulling, the scraper device 3 integrated with the fixed support plate 16 moves forward. The dynamic running is started, and thus, during the forward running, the urine in the ureter 20 is extruded and removed forward by the urine cleaning tool 22 that has stood up. Thus, after completion of the defecation and urine removal work,
If the rope 5 is towed in the backward direction so that the scraper device 3 can be moved backward by the rope 5, the scraper device 3 does not move immediately, and first, the rope connecting rod 17
Contrary to the above, from the solid line shown in FIG. 4 to the phantom line, that is, the pin 36 is moved backward from the front end to the rear end of the elongated hole 35 of the pin 36. Since the movable support plate 37 also moves backward, the operating rod 3 connected to this is also movable.
8, the urine cleaning tool 22 is pulled rearward, and accordingly, the urine cleaning tool 22 rotates in a tilting direction around the fulcrum shaft 25, and the urinary canal 20 is rotated from the inner peripheral surface to the outer peripheral edge thereof. The phantom is brought into the tilted state of the original virtual line. After that, by the subsequent pulling in the backward direction by the cord 5, the scraper device 3 starts the backward traveling, and the urine cleaning device 2
No. 2 is in the inoperative state and returns to its original position even if the vehicle reciprocates smoothly without wear.

Thus, the urine cleaning tool 22 is forced to stand up before the forward movement of the scraper device 3 is started, and the urine in the ureter 20 is removed backward at the same time as the forward movement thereafter. Is sufficiently performed without leakage, the urine cleaning tool 22 is forcibly tilted to be separated from the inside of the ureter 20 before the start of the backward movement, and without performing urine removal work, The forward movement of the scraper device 3 can be smoothly performed, and the urine cleaning tool 22 is prevented from being worn or damaged due to sliding with the inner peripheral surface of the ureter 20, thereby extending the service life.

Although not shown, the urine cleaning tool 22 is arranged rearward of the fixed support plate 16 and the support rod 21 is extended rearward from the fixed support plate 16 in the same manner as described above. Even if the working rod 38 is configured to extend backward from the movable support plate 37 that is integral with the cord connecting rod 17 and is connected to the urine cleaning tool 22, the same action as described above is provided. It goes without saying that it is configured as a manure and separation device for achieving the object of the present invention.

Until now, the scraper device 3 has the inclined bottom surfaces 2a, 2a of the pit 2 during its reciprocating travel.
Since it tends to float up due to the swelling parts such as sticky feces and straw waste, the urine cleaning tool 22 connected to the fixed support plate 16 and the support rod 21 also moves upward due to the rise, and in particular, When the ureter 20 is in a standing state in which it closely slides on the inner peripheral surface of the ureter 20, the upper portion of the inner peripheral surface of the ureter 20 is strongly pressed against the inner peripheral surface of the ureter 20 and tends to inhibit forward movement of the scraper device 3.

In order to prevent such a tendency, the present invention improves the scraper device 3 as follows, for example. That is, the pair of left and right scrapers 3b, 3b are made of wear-resistant metal or rubber or the like at the tips of the shoes 3b.
While the wheels 42, 42 are provided on the outer surface of the substrate 3h of g, 3g, on the left and right vertical wall surfaces 2b, 2b of the pit 2, in the length direction thereof, a fitting recess having a U-shaped cross section parallel to the bottom surface 2 is formed. Groove 4
3, 43 are provided so that the wheels 42, 42 can be inserted and engaged in the corresponding recessed grooves 43, 43 as the left and right scrapers 3b, 3b are opened and closed, and in the inserted state. The inside of the concave grooves 43, 43 is configured to roll along the groove. The wheel 42 is connected to the substrate 3 of the shoe 3g.
It is rotatably connected via a bearing 42b on the outer periphery of an axle 42a that projects horizontally from the center of h. In the drawing, 42c indicates a bearing stop washer, and 42d indicates a stop bolt. The fitting concave groove 43 is formed by previously binding a long metal groove frame 44 integrally to the concrete ground having a U-shaped cross section which forms the fitting concave groove 43. Preferred, according to which the wheel 4
2 is a stable and durable guide groove, which is advantageous.

As described above, according to the present invention, the urine groove having a guide passage in the middle in the longitudinal direction at the center of the left and right inclined bottom surfaces of the cow dung accumulation pit and the bottom surface communicating with the lower end thereof. Since the ureters that are parallel to the floor are provided, it is possible to separate the urine released from the fecal-urine mixture deposited on the floor from the accumulated feces by the inflow of the urine into the ureter. The scraper device is provided with a fixed support plate that hangs down from the scraper device and extends into the ureter while penetrating the urine groove, and a fulcrum is provided on the urine cleaner provided in the ureter by a support rod connected to the fixed support plate. While connecting via a shaft, a horizontally extending line connecting rod provided so as to be movable forward and backward with respect to the fixed support plate is accommodated in the guide passage, and is suspended from the line connecting rod and the urine groove. The cord connecting rod that penetrates through the ureter and faces the inside of the ureter Since the supporting plate movable together is provided, and the operating rod connected to the movable supporting plate is connected to the urine cleaning tool, the scraper device is forwardly moved by the rope to travel forward or backward in the pit. When tow in the direction or the backward direction, the urine cleaning tool is first erected or tilted in conjunction with this, and then the forward or backward movement of the scraper device is performed by the subsequent towing. In the forward running, scrape removal of feces and urine squeeze cleaning can be performed at the same time, and in the backward running, smooth recovery can be obtained in an inoperative state of removing feces and urine. In this case, since the cord connecting rod is connected to the fixed support plate through the long hole and the pin, the fixed support plate is made thin to penetrate the urine groove having an extremely narrow width, and is suspended in the ureter. The cord connecting rod can be housed in a guide passage provided in the middle of the urine groove so as to move forward and backward. In this case, by setting the width of the urinary groove to a maximum of about 12 mm, dropping of feces into the urinary groove can be prevented as much as possible, and the cow's hoof does not fall into the urinary groove for safe walking. Can be guaranteed. Further, when the opposing vertical groove wall and the ureter are integrally formed into a frame body, the urine groove having a guide passage bulging in the middle, the ureter communicating with the lower surface of the urine groove, and the manure accumulation in the central portion The pit construction work can be performed with high efficiency.
