Description

  The present invention relates to a leveling system of a barn with sawdust floors for raising pigs and cows.

The so-called sawdust pig house has a form in which a floor portion is excavated by about 30 cm, and organic waste such as sawdust, bark, and rice husk is spread there to form a floor, and pigs are raised there. Because the flooring is a natural organic matter, it can also be used as feed for pigs, and by mixing bacteria that fermentatively decompose pig manure, it can be used to ferment and decompose pig excreta, making it a large septic tank. In addition to being able to carry out the treatment of manure at the breeding site without requiring a manure treatment facility, it is practically used as an excellent pig farming system in that it does not cause bad odor or the like, flies and worms. However, in the current sawdust pig house, about 5 to 6 pigs are kept in a rowhouse space partitioned to about 33 m ² . There is a pig's habit of excretion in a specific place, distinct from the place where they usually spend, and excretion is usually done in one corner of the compartment space. Since the depth of the saw bed is at most 30 cm, the water is not sufficiently absorbed, and the floor in that part becomes loose due to manure, and the fermentation does not catch up and gives off a bad odor. Therefore, an operation is performed in which the upper and lower layer portions of the floor material saw are cut back and mixed with the floors of other portions. This work is a burden for pig farmers because large pigs cannot be put in a conventional piggery and it is dependent on manpower.

  Patent Document 1 proposes an improved technique for this kind of sawdust pig house. The present invention can save labor compared to conventional breeding methods, is free from soil contamination, and can be used as a feed or organic fertilizer, and is optimal for large livestock such as cattle and horses. The large-scale livestock breeding facility disclosed therein has sawdust, straw, rice husk, branch tree, bark, wood chip, bark on the floor. Depth of at least 1 m or more by using a carbonaceous base material comprising a duct, paper waste, etc., or a mixture selected from these as an active mixed microorganism having a fermentative decomposition action of animal excrement The rearing line is laid to have a rearing space by the partition fence, and the traveling rail is suspended from the ceiling along the rearing line in the vicinity of the upper space of the partition fence. Te provided movably on the running rail and is characterized in that a forward turning machine for stirring the flooring described above laid.

In this invention, the depth of the layer of sawdust was increased to 1 m, so that the ability to absorb moisture was increased, and a turning-over machine was installed in the barn to stir the flooring. The problem is improved, but when the floor material is stirred and turned over, the partition member 2 is swung to move the pig from the breeding space C to the driving space E as shown in FIG. The pigs must be kept there, which is a labor-intensive operation. Further, the turning-over machine for agitating the flooring material adopts a configuration as shown in FIG. 7, and includes a drive wheel 16 disposed at the lower end of the frame 15 so as to be movable in the breeding space. The traveling motor 17 disposed on the upper side is configured to be able to travel on the traveling rail 8 by being driven through the chain 18. However, in order to dig up the floor material 11 having a length of about 1 m, this turning machine M has a strip (flat bar) projection 12a on the surface perpendicular to the rotation direction between the sprockets 12A and 12B disposed at both ends. The turning member 12 formed by winding the endless belt 12C horizontally disposed at an appropriate interval is attached to the frame 15 with the tip of the turning member 12 around the pivot shaft 13 and the winding wire 14 A screw-shaped cutting device that is configured to be able to swing up and down from the state shown by the solid line to the state shown by the two-dot chain line by moving up and down, and once transports the flooring 11 into the frame 15 and installed in the frame 15 After being crushed while being brought into contact with the outside air by 19, it is discharged downward from the discharge port 19 a. Thus, the turning-over machine which stirs the flooring material has a complicated structure, and the work becomes large-scale, and a wide working space in which the livestock is excluded must be secured. In addition, after the turn-over operation, a large step is generated on the floor, and an operation for smoothing it is also necessary. In addition, since this barn has a structure in which the partition member 2 drives the pig to rotate around the vertical axis, the front of the barn has a scale of up to about 4 m.

Therefore, the upper and lower layers can be turned over at that position without transporting the saw. And since the mechanism which moves this vertical direction screw in the area | region where the saw saw was spread is provided, it can move to every corner of the area where the saw saw was spread, and the work of turning can be performed. Exothermic fermentation by microorganisms is promoted throughout the breeding space, providing a warm environment for livestock, and is particularly suitable in winter. Further, since the present invention is provided with the livestock raising means attached to the longitudinal screw, it is not necessary to evacuate the livestock during this work, and the livestock is evacuated to another place by this raising means. It is safe without touching the screw.
Further, the sawdust barn floor leveling system of the present invention is preferably provided with an air supply pipe in the lower layer portion of the sawdust, and air is supplied from the opening of the air supply pipe, so that the fermentation action by microorganisms is promoted.

  An embodiment of a sawdust barn management system according to the present invention will be described with reference to FIGS. 1 and 2. The one shown here is designed for pig houses. FIG. 1 is a cross-sectional view orthogonal to the longitudinal direction of the barn, and shows one of the generally symmetric structures, FIG. 2 is a plan view of the barn where the repeating structure in the longitudinal direction is partially omitted, and FIG. It is a figure explaining the form of the machine which performs stirring and switching back in a barn. In the plan view of FIG. 2, the central portion A is a passage when workers and livestock are received and shipped, and both side regions B of the passage are a work space in which the feeder 4 and the measuring device 5 are arranged, and a wide space C on both outer sides. Is a breeding space in which saws 1 are spread, and is divided by a low partition plate 2 at appropriate intervals in the longitudinal direction (for example, 20 m) in order to raise an appropriate number of pigs. Sawdust is mainly composed of sawdust, and organic waste such as bark, rice husks, and firewood is mixed. Conventional ones may be used, but the layer thickness is about 1 m (80-150 cm) to increase the water absorption. is necessary. The machine M is used to perform stirring and turning, but since the necessary upper and lower layer turning and work area is narrow and the flatness after work is excellent, in the present invention, the rotationally driven longitudinal screw is used. adopt. Generally, two longitudinal screws m1 are arranged in parallel at an interval of about 1 m. This is because saws carried by a plurality of screws interfere with each other to synergize the pulverization and stirring action, thereby further promoting fermentation by microorganisms. As shown in FIG. 3, the structure of the vertical screw m1 is such that a screw is formed in a lower part of the long axis, a part slightly longer than the layer thickness of the saw blade 1, and a motor that rotationally drives the vertical screw m1. It is attached in a form that hangs downward from the lower surface of the carriage m3 in which m2 is stored.

  The present invention includes a moving mechanism so that the turn-back machine M can move over the breeding space C where the saws are spread. That is, in this embodiment, the first rail L1 is installed on both side walls in the longitudinal direction of the breeding space, and the traveling members N that run on the first rail L1 are arranged on both sides, and the both side walls A second rail L2 is passed between the traveling members N. The carriage member m3 is arranged so as to travel on the second rail L2, and the traveling member N and the carriage member m3 are respectively provided with drive motors (not shown) for moving on the rail. Yes. The carriage member m3 on which the vertical screw m1 is installed by these drive motors is reciprocated (in the X direction) on the second rail L2, and the second rail L2 itself on which the carriage m3 moves is reared. Since it can be moved in the longitudinal direction (Y direction) of the space C, the carriage member m3 on which the vertical screw m1 is installed can appropriately scan the inside of the breeding space C two-dimensionally. In general, the carriage member m3 is a slow continuous reciprocating motion, and the traveling member N is intermittently stepped by a distance exceeding the width between the vertical screws every time the carriage member m3 reaches the end. Then, the work is turned back while moving in a meandering form. Incidentally, in this embodiment, since the width between the two vertical screws is 1 m, the step is 1 m or more. This turn-back machine M does not need to be installed in each section of the breeding space C, and can be shared in sections that are continuous in the longitudinal direction. As shown in FIG. ing. In addition, when moving the turn-back machine M, the partition plate that appropriately partitions the breeding space C becomes an obstacle, but the mechanism that the partition plate 2 moves such that the pig does not move and the door can be opened as long as the machine can pass is passed. Can be dealt with by providing

  As shown in FIG. 1, air supply pipes having openings provided at appropriate intervals above the floor of the breeding space C are provided at predetermined intervals, and are forced by the blower 6 as schematically shown in FIG. Air supply is performed. In the sawdust, exothermic fermentation is carried out by the action of microorganisms, and the supply of air into the sawtooth by the turnover operation and the supply of air from this air supply pipe interact to promote exothermic fermentation and to evaporate moisture. Facilitate. A large amount of the evaporated vapor is guided to the high ceiling in the center of the barn and released from the window to the outside air. In a conventional sawdust barn, a large amount of moisture tends to accumulate and corrode the structural iron material. By adopting this configuration, moisture is efficiently released to the outside air, and the durability of the structure is also increased. When a large amount of water has accumulated, this air supply pipe can be switched to a water distribution pipe.

  A major feature of the present invention is that the operation of stirring and turning back saws can be carried out while keeping livestock. For this purpose, a configuration including livestock raising means 3 attached to the vertical screw m1 is adopted. Although many livestock can be kept in the wide breeding space C, it is necessary to avoid being injured by being caught in the machine. The moving speed of the machine is as slow as about 50 cm / min. In this embodiment, as shown in FIG. 4, a system in which high voltage electricity is applied without any danger is employed as the follow-up means 3. The livestock feels tingling as soon as they are touched, so they are surprised and evacuated. In the example shown in FIG. 3, the frame 3a is hung from the carriage m3 with a rod, and a voltage terminal is wound around it so that a voltage is applied to it, so that it can move up and down according to the level of the saw. did. The chasing means 3 is not limited to this, and it is also possible to adopt a method such as chasing and rotating the hammer.

  As described above, the sawdust barn floor leveling system of the present invention rotates the vertical screw with a motor to stir and turn the sawtooth, and the turning machine moves by using the motor to step the traveling member and the carriage member. Since it is a continuous reciprocating drive and the livestock purging means is also automatically operated, there is no need for a person to stick constantly, and the step width of the traveling member and the continuous driving speed of the cart member are set appropriately. If so, it can be automatically operated under the control mechanism. Since the fermentation by microorganisms becomes more active as the stirring and turning operation is frequently performed, the preferred form is to measure the difference between the sawtooth temperature and the outside air temperature and adjust the step width of the traveling member according to the difference. Good. In winter, fermenting heat provides a warm environment for livestock, but in summer, if fermenting heat is too high, it can be painful for livestock, and it may cause physical health problems. Therefore, in the present invention, when the fermentation heat is too high, the step width of the traveling member N is increased, and the line where the turnover operation is performed and the line interval where the turnover operation is performed next is widened so that the livestock has a low temperature region between them. So that you can spend time there. Basically, by making the line that was not performed at the time of the next scanning the work line, the fermentation state of the entire region is made uniform.

Next, an embodiment of the present invention will be shown. One breeding space C has a width dimension of 8.3 m, a working space B has a width dimension of 3 m, and the central passage A has a length of 2 m. . The layer thickness of the sawdust was 120 cm, and the floor position of the work space B was a concrete floor aligned with the same level as the top surface of the sawdust. The height of the first rail L1 is 3.3 m from the floor position where the air supply pipe is piped, the total length is 60 m, and the lowest ceiling position at both ends in the width direction of the breeding space C arranged on both sides is 4.8 m. It was. The stirring / turning machine M has the form shown in FIG. 3 and the distance between the two vertical screws m1 is 1 m, the distance between the lower tip and the floor position is 20 cm, and the length of 120 cm is the screw. The livestock keeping means 3 is configured such that the frame 3a is hung from the above-described carriage m3 with a rod, and a voltage terminal is wound around it to apply a voltage thereto. The scale of this pig house is designed to raise 250 animals. Since the agitating / turning-back machine M in the form of a vertical screw reciprocates on the second rail L2 that is beamed to the traveling member N that moves on the first rail L1 on both sides, the breeding space is up to about 10 m. The width of C can be taken, and by arranging this on both sides, it was possible to realize a pig house with an epoch-making scale as described above.
What is shown as 5 in FIG. 2 is a measuring instrument installed in a Y-shaped passage, and weighs one by one, and pigs that are sized to be shipped can be shipped from one of the Y-shaped items. The pigs that have been selected and have not yet reached the predetermined value are designed to be fed from the other side of the Y-shape to the working space B, fed by the feeder 4, and returned to the breeding space C.
