Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an improvement in an excrement processing device that automatically separates and processes excrement from livestock such as pigs kept in a livestock shed.

"Prior Art and its Problems" Various excrement separation and treatment devices have been proposed for the hygiene management of livestock barns, which constantly clean livestock barns and separate livestock excrement into excrement and waste fluid. , recently, special public service 1975-3
No. 7214 is known.

This device is provided with a reciprocating movable frame on a manure receiving bed with a slit and a drainage pipe arranged in communication with each other in the lower part, and a connector is slidably fitted in the center of the movable frame. At the center of the moving frame and below the connector, the base of a feces removal plate for removing accumulated feces on the excrement receiving bed is pivotally mounted, and the feces removal plate is movable up and down. Further, the connecting tool is provided with a rod for pulling up the feces removal plate. When the movable frame moves back, the manure removal board is lifted to the top of the manure receiving bed by pushing the pull-up guide provided on the manure removal board with a bow raising rod. It comes into contact with the manure receiving bed and removes the accumulated feces on the manure receiving bed.

However, when the conventional device moves forward, that is, when removing feces,
The feces removal plate slides against the feces and urine receiving bed using only its own weight, so if the load applied to the feces and urine plate is small while it is moving, it will often go over the feces on the feces and urine receiving bed. In some cases, it may not be possible to completely remove feces, and if feces is stuck between the feces removal plate and the movable frame, it may interfere with the sliding movement, and feces may not be removed. . Further, since the feces removal plate moves a considerable distance in the forward movement direction without slidingly contacting the excrement receiving bed, it may become impossible to perform feces removal work during that time. In addition, when feces is stuck on the excreta receiving bed, the feces cannot be scraped off, and this feces becomes an obstacle to the progress of the so-called scraper, which includes the feces removal plate and moving frame, causing the device to stop moving. There was also the problem of putting it away. Furthermore, in the conventional apparatus, the reciprocating movement of the entire apparatus such as the moving frame is performed by external equipment such as a winch, and therefore, it is necessary to repair these external equipment due to wear and tear, or to provide extra installation space for this purpose.

``Object of the Invention'' Therefore, the present invention enables the feces removal plate to operate smoothly at all times, eliminates the loss of feces removal operation, constantly scrapes off feces that are strongly stuck on the feces and urine receiving bed, and furthermore, does not require external equipment for moving the device. The purpose of the present invention is to obtain an excrement separation and treatment device for livestock barns that can be made unnecessary.

``Summary of the Invention'' The present invention provides that, during excrement removal operation, if the excrement removal plate is simply slid into contact with the excrement receiving bed due to its own weight, the excrement strongly stuck to the connecting parts and both sides of the excrement removal plate will become an obstacle. The starting point is that it is impossible to completely scrape off the accumulated feces on the manure receiving bed because the sliding action of the feces removal plate is obstructed, and when this feces removal operation is performed, the feces removal plate is forcibly moved. It was completed based on the idea that it would be possible to make the device slide into contact with the excrement receiving bed, and also to make the movement of the device self-propelled, so that the raising and lowering of the excreta plate could be done at the start of self-propelled movement.

The excrement separation and treatment device for a livestock barn of the present invention embodies this idea by providing upright walls facing both sides of the manure receiving bed, and connecting the movable body to the inner wall of the upright wall so that the movable body is placed on the manure receiving bed. A self-propelled mechanism is provided for reciprocating self-propulsion, and the feces removal plate is provided with a lifting mechanism that raises the feces removal plate to a laid down position where it slides into contact with the excrement receiving bed and an upright separated position away from the excrement receiving bed. The invention is characterized in that the lowering and raising operations of the excreta plate by the raising and lowering mechanism are respectively synchronized with the forward self-propelling operation and backward self-propelling operation of the self-propelling mechanism.

The scraper part 20 includes scraper side plates 21a and 22a.
A fecal removal plate 26 is provided between the two. The feces removal plate 26 is for removing the feces accumulated on the excrement receiving bed 13, and its bent portion is pivotally connected to a plurality of hinge parts 27 provided along the longitudinal direction of the support member 25, and the feces removal plate 26 removes the accumulated feces on the excrement receiving bed 13. It can be swung between a lying position where it lies down on the excrement receiving bed 13 and an upright separated position where it is separated from the excrement receiving bed 13 in a substantially parallel manner. This feces removal plate 26 includes a feces removal part 26a which is inclined downward from a hinge part 27 toward the excrement receiving bed 13 and whose tip part can slide into contact with the excrement receiving bed 13, and a hinge part 27.
It is provided with a standing portion 26b that stands up from the top and extends upward.

The distal end of the excrement removing part 26a can be formed into a knife shape in order to enhance the excrement removal effect. In addition, at the lower end of the scraper side plate 21a (22a), there is a excrement receiving bed 1.
A sliding member 28 such as a sled is fixed in sliding contact with the scraper portion 3 to facilitate reciprocating sliding of the scraper portion 20.

At a position corresponding to the slit 14 at the center of the support member 25,
A slit scraping plate 29 is fixedly hanging down. This slit scraper plate 29 is loosely inserted into the slit 14 and its lower end is connected to the drain pipe 1.
A disk-shaped urine collecting plate 30 having a smaller inner diameter than the drain pipe 15 is provided at the protruding end thereof.

This urine collecting plate 30 collects the drained liquid inside the drain pipe 15 while moving, and flushes it to the fertilization 16 provided at the end thereof. Therefore, the slit scraping plate 29, the urine collecting plate 30 and the excrement removing plate 26 are connected to the scraper section 20 and the movable body 31.
Along with the reciprocating movement, they reciprocate integrally in the left-right direction in FIG. 2 and in the up-down direction in FIG. 3.

The moving body 31 is covered with a cover 31a, and wheels 34 are rotatably supported via an axle 33 in a tire house 32 below the left and right moving body side plates 21b and 22b. The axle 34 is preferably made of a normal tire, and its ground contact surface is preferably provided with anti-slip irregularities.

A rack rail 35 is provided on the inner wall 11a of the opposing foundation wall 11.
is provided along the rack rail 35, and each of the rack rails 35 has a window 21c (
22c), from the moving body 31 side to the self-propelled gear 36.3.
7 are engaged. The self-propelled gears 36, 37 are driven by a motor 38 to rotate in opposite directions. That is, as shown in FIG. 2, the drive shaft 39 of the motor 38
A drive gear 40 and a drive sprocket 41 are fixed coaxially, and this drive sprocket 41 is connected to the cheno 4.
A driven sprocket 43 coaxial with the self-propelled gear 36 via 2
It is connected to. The drive gear 40 also includes a driven gear 44.
A sprocket 45 coaxial with the driven gear 44 is connected via a chino 46 to a driven sprocket 47 coaxial with the self-propelled gear 37 . Therefore, when the motor 38 is driven, the self-propelled gear 36 rotates via the drive sprocket 41, chain 42, and driven sprocket 43, and the self-propelled gear 37 also rotates via the drive gear 40, driven gear 44, sprocket 45, chain 46 and a driven sprocket 47, the movable body 31 and the scraper part 20 are reciprocated on the excrement receiving bed 13 by rotating simultaneously in the opposite direction to the self-propelled gear 36 and meshing with these rack rails 35. Note that the motor 38 rotates normally when the moving body 31
and the scraper section 20 is moved in the forward direction, and reversal moves the scraper section 20 in the backward direction.

A cylinder device 50 serving as a lifting mechanism is connected to the dropping plate 26 in order to raise the dropping plate 26 around the hinge portion 27 between a collapsed position and an erected apart position. The cylinder device 50 is supported by a support member 51 at the center of the inner surface of the top plate portion 31b, and the tip of the operating rod 52 is connected to a connecting member 53 at the center of the upright portion 26b of the feces removal plate 26.
are connected via. Therefore, the fecal removal plate 2
6 is pulled up to the upright position when the actuating rod 52 is drawn into the cylinder, and swings to the collapsed position when pushed out. The raising and lowering operation of the cylinder device 50 is synchronized with the drive of the motor 38 that makes the movable body 31 and the scraper section 20 self-propel, and the cylinder device 50 is operated at the same time as the motor 38 is driven. That is, in response to the normal rotation drive and reverse rotation drive of the motor 38, the cylinder device 50 performs a lowering operation and an upright operation, respectively.

The cylinder device 50 includes limit switches 54 and 5.
5 are attached. These limit switches 54 and 55
serves to stop the operation of the cylinder device 50 when the actuating rod 52 reaches a predetermined position. The control timing of these limit switches 54 and 55 is determined by the actuating rod 52.
is pushed out, and the feces removal part 26a of the feces removal plate 26 reaches the excrement receiving bed 1.
3, and a position in which the actuating rod 52 is pulled in and the excreta removal part 26a stands up substantially parallel to the excrement receiving bed 13, and is sufficiently spaced apart from the excrement receiving bed 13.

Next, the operation of the excrement separation and treatment apparatus having the above configuration will be explained.

When the motor 38 is driven in the normal direction with the device of the present invention in the backward motion restriction position at the end of the excrement receiving bed 13 (the left end in FIG. 4) and the excrement removal plate 26 in the upright and separated position, 37 rotate at the same time and advance while engaging with the rack rail 35. As a result, the movable body 31 and the scraper section 20 move together on the excrement receiving bed 13 in the forward movement direction.

Simultaneously with the driving of the motor 38, the cylinder device 50 works to push out the actuating rod 52, and the fecal removal plate 26 moves to the hinge portion 2.
7 in the direction of collapse, and the excrement removal part 26a is pressed onto the excrement receiving bed 13. At this time, the limit switch 54 operates and stops the operation of the cylinder device 50.
Therefore, the excrement removal plate 26 is lowered onto the excrement receiving bed 13 almost at the same time as the motor 38 is driven, so no movement loss occurs. Then, while maintaining this state, the scraper section 20 and the movable body 31 move on the excrement receiving bed 13 in the forward direction. In this way, the tip of the excrement removal part 26a that slides forward can easily scrape off the excrement that is stuck on the excrement receiving bed 13 and is difficult to remove. Therefore, during forward movement, it is possible to realize a clean surface of the excrement receiving bed 13 without any residue on the excrement receiving bed 13. Furthermore, since the dropping operation of the feces removal plate 26 is forcibly performed by the cylinder device 50, there is no possibility that the movement of the dung removal plate 26 is obstructed by stuck feces, and smooth movement during forward movement is ensured. . At the same time as the excrement removing plate 26 advances, the slit scraping plate 29 provided at the rear of the movable body 31 moves within the slit 14 to remove the clogging of the slit 14, and the urine collecting plate 30 moves into the drain pipe 15. The drainage liquid is washed away. Then, the excrement removal section 26
The movable body 31 and the scraper section 20 stop when the movable body 31 and the scraper part 20 reach a position above the receiving tank 16 disposed at the end of the excrement receiving bed 13 (return movement restriction position).

From this state, when the motor 38 is driven in the reverse direction, the self-propelled gears 36 and 37 rotate in the reverse direction using the same rotation transmission path as in the forward movement, and while meshing with the rack rail 35, the moving body 3
1 and the scraper section 20 are self-propelled on the excrement receiving bed 13 in the backward motion direction. At this time, the cylinder device 50 operates simultaneously,
Retract the actuation rod 52. With this, the feces removal plate 26 swings in the upright direction, and the feces removal part 26a is pulled up while maintaining a sufficient distance from the excrement receiving bed 13. In this state, the limit switch 55 operates to stop the operation of the cylinder device 50.

The fecal removal plate 26 now returns to its original state. Thereafter, while maintaining this state, the movable body 31 and the scraper section 20 move on their own in the backward movement direction, come to the backward movement restriction position, and stop. During self-propulsion, the excrement removing part 26a remains raised with a considerable distance from the surface of the excrement receiving bed 13, so that interference with excrement newly deposited on the excrement receiving bed 13 can be avoided.

In addition, in the above embodiment, the moving body 31 and the scraper section 20
The mechanism for self-propelling the rack rail 35 and the self-propelling gears 36 and 37 that mesh with the rack rail 35 is configured, but the inner wall 11a side is formed with a rough surface, and the movable body 31 side is provided with a driving tire having a large frictional resistance. It is also possible to provide In short, it is sufficient to provide a mechanism between the upright wall 11 and the movable body 31 to allow the movable body 31 to move back and forth.

Further, as the raising/lowering mechanism, in the embodiment, the cylinder device 50 is connected to the feces removing plate 26, but any mechanism that raises and swings the feces removing plate 26 may be used. It is also possible to connect one end of a rack that can move forward and backward, and to engage a drive gear with this rack.

"Effects of the Invention" As explained above, according to the present invention, the raising and lowering mechanism works in synchronization with the self-propelling mechanism that makes the movable body self-propel. The dung plate is pressed against the feces and urine receiving bed and comes into sliding contact. Therefore, there is no movement loss in the feces removal operation, and feces that are strongly stuck on the feces and urine receiving bed can be easily scraped off. Further, since the feces removal plate is forcibly lowered by the raising and lowering mechanism, even if feces is stuck to the connecting portion or both sides of the feces removal plate, smooth swinging operation of the feces removal plate is ensured. Further, when the movable body moves back, the feces removal plate is raised to a position where it does not interfere with the excrement receiving bed by the raising/lowering mechanism, so that the top of the excrement receiving bed is not soiled. Furthermore, since the movable body is self-propelled by the self-propelled mechanism, external equipment for reciprocating the movable body and repair of the equipment can be made unnecessary.
