Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an improvement in an excrement separation and treatment device that automatically separates and processes excreta 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 Publication No. 55-37214 is known.

This device has a movable frame that can be reciprocated over a manure receiving bed with a slit and a drainage pipe arranged in communication with each other at the bottom, 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 under the excrement receiving bed is pivotally mounted, and the feces removal plate is movable up and down. Also,
The connecting tool is provided with a rod for pulling up the feces removal plate. When the movable frame returns, the feces removal board is lifted to the top of the excrement receiving bed by pushing the pulling guide provided on the feces removal board with a lifting rod, and when moving forward, it is lifted by its own weight. Then it comes into contact with the excrement receiving bed,
It is designed to remove accumulated feces on the feces receiving bed.

However, in the conventional device, when moving forward, that is, when the feces removal operation is performed, the feces removal plate slides against the excrement receiving bed using only its own weight, so if the load applied to the feces removal plate is small while it is moving, It is not uncommon for the feces on the manure receiving bed to be climbed over, and it may not be possible to completely remove feces from the manure receiving bed.
If feces were stuck between the feces removal plate and the moving frame, the sliding movement would be hindered, and feces could 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 excrement receiving bed, the feces cannot be scraped off, and this feces becomes an obstacle to the movement of the so-called scraper, which includes the feces removal plate and moving frame, and the movement of the device stops. There was also the problem of putting it away. Furthermore, in conventional equipment, the reciprocating movement of the entire equipment, such as the moving frame, is performed using external equipment such as a winch, which requires repair of wear and tear on these external equipment, or extra equipment space for this purpose. .

``Object of the Invention'' Accordingly, the present invention enables the feces removal board to operate smoothly at all times, reduces loss in feces removal operation, constantly scrapes off feces that are strongly stuck to the feces and urine receiving bed, and provides external equipment for moving the device. To provide an excrement separation and treatment device for a livestock shed, which eliminates the need for the reciprocating self-propulsion of a movable body and allows the raising/lowering operation and raising/stopping of a manure removal plate to be performed in conjunction with each other.

[Summary of the invention]

The present invention is designed to prevent the removal of feces due to the fact that if the feces removal plate is simply slid into contact with the excrement receiving bed due to its own weight, the feces strongly stuck to the joints and both sides of the feces removal plate will become an obstacle. The sliding movement of the poop plate is obstructed,
Starting from the fact that it is impossible to completely scrape off the accumulated feces on the feces receiving bed, during this feces removal operation,
This was completed based on the idea that the feces removal plate could be forcibly brought into sliding contact with the excrement receiving bed, and the movement of raising and lowering the feces removal plate could be performed at the beginning of the self-propelled reciprocating movement of the moving body.

The present invention, which embodies this idea, is a self-propelled mobile body equipped with a self-propelled mechanism and a mechanism for raising and lowering a feces removal plate.
A control means is provided for operating the raising/lowering mechanism in synchronization with the driving of the self-propelled mechanism and stopping the operation of the raising/lowering mechanism when the excrement removal plate is in the folded position relative to the excrement receiving bed or in the raised and separated position. shall be.

“Embodiments of the invention” The invention will be explained below with reference to illustrated embodiments.

Reference numeral 11 denotes concrete foundation walls, which are arranged in parallel in a semi-buried state in the ground of the livestock barn, with their wall surfaces facing each other. A slatted step board 12 is placed on this foundation wall 11, spanning both sides. Under the interior defined by the foundation wall 11, a long excrement receiving bed 13 is fixed with concrete. This excreta receiving bed 13 has a slope that slopes downward from both left and right sides toward the center, and is designed to collect mainly waste water from livestock at the center. A slit 14 is formed in the center of the excrement receiving bed 13 along its longitudinal direction to serve as a drainage passage, and a cylindrical drainage pipe 15 is disposed under the slit 14 in communication.
At one end of the excrement receiving bed 13 and the drain pipe 15, a receiving tank 16 for collecting excrement is installed.

On the left and right side ends of the excrement receiving bed 13, a scraper part 20 and a movable body 31 are provided as a pair in the front and rear, and are movable back and forth in the longitudinal direction. For the scraper section 20 and the movable body 31, the leftward movement in FIGS. 1 and 3 is the forward movement direction, and the rightward movement is the backward movement direction. The scraper section 20 and the movable body 31 are provided with a pair of left and right side plates 21 and 22.
are the connecting frame 23 at the top of the front end and the connecting frame 2 at the top of the rear end.
4, its front part is a scraper side plate 21a (22a), and its rear part is a moving body side plate 21b.
(22b). In addition, side plates 21 and 2
A support member 25 is provided near the center of the lower part of 2 so as to straddle both.

The scraper part 20 includes a scraper side plate 21a.
A fecal removal plate 26 is provided between and 22a. The excrement removal plate 26 is for removing accumulated excrement on the excrement receiving bed 13, and a bent portion thereof is slidably pivoted to a plurality of hinge portions 27 provided along the longitudinal direction of the support member 25. ing. This fecal removal plate 26 has a hinge portion 2
The excrement removal part 2 is inclined downwardly from 7 to the excrement receiving bed 13, and the tip part can slide into contact with the excrement receiving bed 13.
6a, and a standing portion 26b that stands up from the hinge portion 27 and extends upward. The tip of the feces removal plate 26a can be formed into a knife edge shape in order to enhance the feces removal effect. Furthermore, a sliding member 28 such as a sled that slides on the scraper side plate 21a (22a) and facilitates the reciprocating sliding of the scraper part 20 is fixed to the lower end of the scraper side plate 21a (22a).

A slit scraping plate 29 is suspended and fixed at the center of the support member 25 at a position corresponding to the slit 14. This slit scraper plate 29 is loosely inserted into the slit 14 and has a lower end protruding into the drain pipe 15, and a disk-shaped urine collection plate 30 smaller than the inner diameter of the drain pipe 15 is attached to the protruding end. It is provided. This urine collecting plate 30 collects the drained liquid inside the drain pipe 15 while moving, and flushes it into the receiving tank 16 provided at the end thereof. Therefore, the slit scraping plate 29, urine collecting plate 30, and excrement removing plate 26 integrally reciprocate in the left-right direction in FIG. 1 as the scraper section 20 and moving body 31 reciprocate.

The movable body 31 is covered with a cover 31a, and a pair of axles 32, 3 are connected via bearings (not shown) between the left and right movable body side plates 21b and 22b.
3 is rotatably supported. Axle 32, 33
Wheels 34 and 35 are fixed at both ends of the movable body side plate 21b (22b), respectively, and an elastic caterpillar 36 made of rubber material or the like is wound between the wheels 34 and 35. ing. Gears 37 and 38 are attached to the axles 32 and 33 at corresponding positions, respectively, and a drive gear 40 of a motor 39 disposed between the axles 32 and 33 meshes with the gears 37 and 38. There is. Therefore, when the motor 39 is driven, its rotational force is transmitted from the drive gear 40 to the gears 37 and 38, respectively.
The caterpillar 36 is rotated in the forward or backward direction via the wheels 34, 35. Now, the moving body 31
is integrated with the scraper part 20 and reciprocates in the longitudinal direction above the excrement receiving bed 13.

In order to swing the excrement removal plate 26 about the hinge part 27, a raising/lowering slide rack 41 is supported at the center of the inner surface of the top plate part 31b so as to be slidable in the front and rear directions by a slide guide 42. .
The raising/lowering slide rack 41 is equipped with guide pins 43 protruding from both sides of the front end.
is fitted into the elongated hole 45 of the swinging connector 44 provided at the upper end of the upright portion 26b of the excrement removing plate 26, and is connected to the swinging connector 44. Therefore, when the feces removal plate 26 slides forward of the slide rack 41 for raising and lowering via the swinging connector 44, the feces removal part 26a of the plate 26 moves toward the excrement receiving bed 1 around the hinge part 27.
3, and swings in an upright direction to separate from the excrement receiving bed 13 by sliding rearward.
Further, the elongated hole 45 is connected to the feces removal plate 26a of the feces removal plate 26.
When the manure reaches the receiving tank 16 which is deeply hollowed out at the end of the forward movement direction of the manure receiving bed 13, the manure removing part 2
6a acts, the swinging connector 44 slides forward within its effective length, and the excrement removing part 26a
This is for further lowering (lodging) into this receiving tank 16.

A pinion 46 is engaged with the raising/lowering slide rack 41 in order to slide the raising/lowering slide rack 41 in the front-back direction. This pinion 46 is supported by the top plate portion 31b, and is connected to a rack slide motor 50 via a driven sprocket 47, a chain 48, and a drive sprocket 49. Therefore, when the rack slide motor 50 is rotationally driven, the raising/lowering slide rack 41 slides in either the front or rear direction due to the rotation of the pinion 46. In this case, the rack slide motor 50 rotates in the normal direction to slide the raising/lowering slide rack 41 forward via the pinion 46, and rotates in the reverse direction to slide it backward.

In order to stop the drive of the rack slide motor 50 at a predetermined sliding position of the slide rack 41 for raising and lowering, a pair of limit switches 51 and 52 are provided near the front and rear of the slide rack 41 for raising and lowering. The limit switches 51 and 52 are for stopping the forward rotation of the rack slide motor 50, and the limit switch 52 is for stopping the rotation of the same motor 50 in the reverse direction. This limit switch 51
The timing of the control in and 52 is such that the raising/lowering slide rack 41 slides forward and the feces removing part 26a of the feces removing plate 26 lies down and is pressed onto the excrement receiving bed 13, and the position where the raising/lowering slide rack 41 slides forward. The rack 41 slides backward, and the excrement removal part 26a is removed from the excrement receiving bed 13.
They are each set to work when the robots stand up from each other and come to positions sufficiently apart from each other.

In order to drive the above-mentioned rack slide motor 50 in synchronization with the self-propulsion of the movable body 31, the gear 37
Driving limit switches 53 and 54 are disposed in the vicinity of and 38, respectively. One of the limit switches 53 and 54 operates when the motor 39 rotates in the normal direction, and the other operates when the motor 39 rotates in the reverse direction.
The motor 39 is connected to the excrement receiving bed 13 via wiring.
It is connected to a distribution board (not shown) located outside the end of the

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

When the motor 39 is driven forward in a state where the device of the present invention is in the backward motion restriction position at the end of the excrement receiving bed 13 and the excrement removal plate 26 is in the position shown in FIG. 4a, the drive gear 4
At zero rotation, the gears 37 and 38 rotate simultaneously to rotate the axles 32 and 33, and the caterpillar 36 moves forward on the side edge of the excrement receiving bed 13 via the wheels 34 and 35. With this, the scraper section 20 and the moving body 31 move together in the forward movement direction.

On the other hand, the limit switch 53 (54) operates in synchronization with the drive of the motor 39, that is, simultaneously with the self-propelled movement of the movable body 31, to drive the rack slide motor 50 in normal rotation. Then, the drive sprocket 49, chain 48 and driven sprocket 47
, the pinion 46 rotates in the same direction, and slides the raising/lowering slide rack 41 forward. The guide pin 43 of the slide rack 41 moves a short distance within the elongated hole 45 and then comes into contact with the front inner end of the slide rack 41, causing the swinging connector 44 to move.
Press forward. As a result, the feces removal plate 26 swings around the hinge in the direction of collapse with respect to the excrement receiving bed 13, and the feces removal part 26a is pressed onto the excrement receiving bed 13 and comes into sliding contact (FIG. 4b). . At this time,
The limit switch 51 operates to stop the rack slide motor 50. During this time, the moving body 31
Because it only moves a short distance by itself, there is little loss in movement of the dung removal plate. 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. with this,
The tip of the excrement removing part 26a that slides forward is connected to the excrement receiving bed 1.
3. Easily scrape off feces that are stuck on the surface and difficult to remove. Therefore, when moving out, the excrement receiving bed 13 is clean with no remaining feces on it.
The third aspect can be realized. In addition, the fecal removal board 2
6 is forcibly performed by the raising/lowering slide rack 41 that engages with the pinion 46.
The situation where the movement of the excrement removal plate 26 is obstructed by stuck excrement is eliminated, and smooth operation during forward movement is ensured. Simultaneously with the advancement of the excrement removal plate 26, the slit scraping plate 29 moves within the slit 14 to remove clogging of the slit 14, and the urine collection plate 30 flushes out the drained liquid in the drain pipe 15. Then, when the tip of the excrement removal part 26a comes to the top of the receiving tank 16, which is disposed by being deeply hollowed out at the end of the excrement receiving bed 13, the weight of the excrement removal plate 26 acts, and the guide pin 43
While moving to the rear inner end of the elongated hole 45, the manure removal plate 2
6 further swings downward (Fig. 4c).
As a result, the feces removal section 26a has a further downward slope, and the feces collected on the feces removal section 26a can easily slide down into the receiving tank 16 due to the slope. As a result, the surface of the excrement receiving bed 13 is cleanly removed, and the excrement is led to the receiving tank 16 along with the drained liquid. At this time, the moving body 31 is stopped at the forward movement restriction position.

From this state, when the motor 39 is driven in the reverse direction, the caterpillar 36 moves backward over the excrement receiving bed 13 in the same rotation transmission path as in the forward movement, and the movable body 31 and the scraper part 20 move in the forward direction. self-propelled to. At the same time, limit switch 5
4 (53) works, and the rack slide motor 50
drive in reverse. Then, the pinion 46 rotates in the same direction, and the raising/lowering slide rack 41 that engages with the pinion 46 slides rearward. As a result, the feces removal plate 26 swings in the upright direction about the hinge portion 27, and the feces removal portion 26a is pulled up while maintaining a sufficient distance from the excrement receiving bed 13. In this state, the limit switch 52 operates to stop driving the rack slide motor 50. The feces removal plate 26 is now returned to the state shown in FIG. 4a.
From then on, while maintaining this state, moving object 3
1 and the scraper section 20 move forward in the forward movement direction and stop at the forward movement restriction position. 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. The unit 20 and the moving body 31 stop.

Note that a pair of raising/lowering slide racks 41 and a drive device for operating them may be provided on both sides of the movable body 31.

Further, in the above embodiment, the urine collection plate 30 is formed into a disk shape, but it can also be shaped to match the bottom shape of the drain pipe 15.

"Effects of the Invention" As explained above, according to the present invention, the raising and lowering mechanism operates in synchronization with the self-propelled mechanism that makes the mobile body self-propel, and this raising and lowering mechanism causes the feces removal plate to be placed on the excrement receiving surface. When it comes to the lodging position or the standing and separating position,
Since the control means stops the operation of the raising and lowering mechanism, when the movable body moves forward, the feces removal plate is pressed against and comes into sliding contact with the excrement receiving bed immediately after the forward movement. Therefore, there is little movement loss in the feces removal operation, and feces that are strongly stuck to the feces and urine receiving bed can be easily scraped off. In addition, the feces removal board is forcibly raised and swung by the raising/lowering mechanism, so even if feces is stuck to the joints or both sides of the feces removal board, smooth rocking operation of the feces removal board is guaranteed. be done. Also, when the moving object returns,
Since the manure removal plate is pulled up to a position where it does not interfere with the manure receiving bed, the manure 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.
