Description

  The present invention inserts an endless transport cable into a feeding pipeline that is piped according to the installation layout of a livestock feeder, and drives the transport cable to transport the feed through the feeding pipeline. The present invention relates to a feed supply device that drops and supplies a feeder through a drop pipe. Specifically, in such a feed supply apparatus, when a plurality of transport pipes are connected and a feeding pipeline is connected, the present invention relates to a joint pipe that connects the transport pipes.

  Conventionally, in this type of feed supply device, when constructing a feeding pipeline, a number of 4 to 5 m standard conveying pipes 1 as shown in FIG. Depending on the installation layout, these long transport pipes 1 are connected by the pipe joint material 3 to connect the pipeline L, and the feed drop holes 1a drilled in each transport pipe 1 in accordance with the dimensions between the feeders. At the position, the drop pipe 4 is connected and suspended as shown partially enlarged in the figure.

  In the conventional feed supply device, when the transport pipe 1 is connected using the pipe joint material 3, the end portion of the transport pipe 1 is connected to the pipe portion of the pipe joint material 3 as shown in FIG. It inserts in 3a, and it fastens with the attachment board part 3b.

  On the other hand, when processing the feed drop hole 1a in the transport pipe 1, at the construction site, for example, measure the distance between the feeders using a measure 5 as shown in FIG. A mark “a” is attached to the mark “a”, and a pilot hole “b” is formed in the mark “a” using the electric drill 7 as shown in FIG. Then, a circular saw saw 7a is attached to the electric drill 7 as shown in (C), and the circular hole c is carefully drilled as shown in (D) with reference to the pilot hole b. Thereafter, burrs generated on the inner and outer sides of the hole edge were scraped off with a round file 8 as shown in (E) and finished as shown in (F) to finish the processing of the feed dropping hole 1a.

  However, conventionally, when constructing a feeding pipeline L, a large number of 4 to 5 m long conveying pipes 1 must be carried into the construction site. Due to the remarkably long objects, there is a problem that the transportation method is limited, and the labor and manpower required for transporting the long pipe is necessary, so that transportation is troublesome and the transportation cost is increased accordingly.

  In addition, conventionally, the feed drop hole 1a has to be processed in the long transport pipe 1 at a working place in a limited space of a barn. Therefore, first, such a long pipe is handled in a narrow work place, and there is a problem that the work efficiency is poor due to its movement and handling. In addition, since it is necessary to drill holes in the transport pipe 1 having a round outer periphery, as shown in FIG. 9, in the stage of preparing the pilot holes b, the positions of the pilot holes are determined on the same axis without being shifted left and right. In addition, it must be machined carefully, and the hole c must be precisely drilled using the hole saw 7a, and the burrs generated at the hole edge of the round hole c can be manually sharpened. In addition to being very time-consuming in drilling, it requires skill, so it cannot be easily processed by a professional plumber, and labor and construction costs increase accordingly. It was.

  By the way, in general, the inside of a barn is frequently subjected to repeated disinfection cleaning in consideration of hygiene and safety, and the feeding pipeline L is also disinfected using a disinfection cleaning device 9 as shown in FIG. 10, for example. Is given. However, since the conventional feeding pipeline L has a structure in which the transport pipe 1 is fastened and connected with a screw-type pipe joint material 3, water and disinfectant from the gap between the mounting plate portions 3 b during disinfection cleaning. Entered the feed in the transport pipe 1 and solidified (calcified) over time, causing the transport pipe to become clogged.

  Therefore, an object of the present invention is to prevent the occurrence of such clogging of the conveying pipe in the feed supply apparatus, which is convenient for conveyance and handling, and can be remarkably reduced in cost, and eliminates drilling on site. It is an object of the present invention to provide a joint pipe that can easily connect a transport pipe in a short time and construct a feeding pipeline without being bothered by a skilled person.

  In order to achieve the object of the invention described above, the invention according to claim 1 is connected to a plurality of transport pipes 11 according to the installation layout of the feeder B, for example, as shown in the embodiment shown below. An endless transport cable 14 is inserted into the feeding pipeline P and communicated with each feeding device B by a drop pipe 13 hanging from the feeding pipeline P at each feeding device position. In the feed supply apparatus, the feed cable 14 is driven in the pipeline P to feed the feed, and is dropped and fed to the feeder B through the drop pipe 13, and the drop pipe 13 is connected at each feeder position. It is a short joint pipe 10 that connects and connects the transport pipe 11, and the inner diameter dimension is adjusted to the outer diameter of the transport pipe 11 at both ends. A feed connecting port 10a having a step diameter is provided, and a feed feeding port having a different diameter according to the difference in the amount of feed supplied to the feed dropping unit 10b between the pipe connecting portions 10a. A plurality of 15, 16, 17 are provided in the circumferential direction, and at the time of piping, one of the feed feeding ports 15, 16, 17 is communicated with the feed dropping port 30 at the upper end of the drop pipe 13 so that the drop pipe 13 is While connecting with the feed drop pipe part 10b, the end part 11a of the said conveyance pipe 11 is rotatably inserted in the said pipe connection part 10a so that it may fit liquid-tightly.

  The invention according to claim 2 is characterized in that, in the joint pipe 10 of the feed supply device according to claim 1, for example, as shown in the following embodiment, it is integrally formed with a resin material.

  The invention according to claim 3 is the joint pipe 10 of the feed supply device according to claim 1 or 2, for example, as shown in the embodiment shown below, on the outer peripheral surface of the feed drop pipe portion 10b, the feed A circular arc pipe-shaped shutter 25 that opens and closes the feeding ports 15, 16, and 17 is rotatably mounted, and the shutter 25 opens one of the feed feeding ports 15, 16, and 17 to form the drop pipe. It is characterized in that the remaining feed feeding port is closed when it is in the rotational position communicating with the 13 feed dropping ports 30.

  According to the first aspect of the present invention, it is not necessary to transport a standard long object and process the feed drop hole at the work site as in the past, and according to the difference in the amount of feed supplied to the feeder. Since the transport pipe is connected using a short pipe joint pipe with feed feed ports with different calibers in advance, (1) it is not restricted by the transport method, reducing the labor and labor of transport, and the transportation cost.

(4) Accordingly, it is possible to eliminate the intervention of outsiders such as plumbers other than those involved in the barn, and to take into account the hygiene and safety issues that are regarded as problems in recent years. (5) Since the joint pipe can be mass-produced in a factory in advance, the overall product cost can be drastically reduced. Furthermore, (6) When it is necessary to adjust the amount of feed to be fed to the feeder, on the feeder that needs to be adjusted, the corresponding joint pipe is rotated as it is with respect to the transport pipe to feed the feed. All you need to do is select one of the feeds to match the desired feed supply you want to change, and connect the feed feed of that selected hole size with the feed drop outlet of the drop pipe, which makes it very easy to feed The hole size of the feeding port can be changed, and there is also a great advantage that it is not necessary to perform a very troublesome drilling process again at the work site. In addition, (7) Each of the transport pipes connected by the joint pipe is short and can be easily detached from the joint pipe individually, so troubles such as disconnection of the transport cable in the feeding pipeline can occur. Even if a problem occurs, it is possible to instantly find and deal with the trouble location, thereby facilitating maintenance work and reducing the cost. (8) The joint pipe has a pipe connecting part for connecting the conveying pipe with an enlarged diameter and a step between the conveying pipe side and the end of the conveying pipe is press-fitted into the pipe connecting part so as to be liquid-tight. The fitted configuration prevents water from entering when disinfecting and cleaning the feeding pipeline, thereby ensuring that troublesome problems that can cause clogging in the transport pipe are prevented. You can also

  According to the invention described in claim 3, by rotating the shutter to open and close one of the feed feeding ports in communication with the feed dropping port of the drop pipe, the feeding pipeline to the feeder While feed feeding can be controlled as needed, at that time, the remaining feed feeding port is closed by the shutter in this rotational position, and feed can be reliably prevented from leaking from the joint pipe.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 7 is a perspective view of the overall configuration of a feed supply apparatus including a feeding pipeline constructed using the joint pipe of the present invention. The illustrated feed supply device, for example, is constructed in a pig house as a feed transportation system for pig farming, and includes a feed replenishment device indicated by reference symbol A in the figure, while a large number of feeders B are installed side by side according to the scale of pig farming. ing. According to the installation layout of the feeder B, the feed supply device A and each feeder B are connected via a feeding pipeline P provided with a plurality of corners and bent. The feed replenishing device A includes a feed tank t that accommodates a large-capacity, for example, powdered feed, and a replenishment hopper h that is connected to the feed tank t under the feed tank t and has a function of appropriately adjusting the feed replenishment amount. ing.

  The feeding pipeline P uses a joint pipe 10 of the present invention, which will be described in detail later, and connects a plurality of straight tubular conveying pipes 11 to form a straight line portion. Similarly, the feeding pipeline P has an arc shape at each corner. Several corners are formed by connecting with the joint pipe 12 and are piped endlessly throughout, and an endless transport cable is inserted into the hollow part so as to be rotatable. In the feeding pipeline P, a driving device D for operating the transport cable is installed at an adjacent position downstream of the feed supply device A in the feed transport direction. The feeder B is connected to the joint pipe 10 at each installation position so as to suspend a drop pipe 13 and communicates with the pipeline P via the drop pipe 13. As shown in the figure, as shown by the reference numeral 14 in FIG. 6, a cable in which several steel wires each having a large number of transport disks 14a fixed at equal intervals are connected to a desired length by a joint fitting is used. Yes.

  Therefore, when the feed is supplied, as shown in FIGS. 6 and 7, the feed supply apparatus feeds the feed stored in the feed tank t into the feed pipeline P while adjusting the replenishment amount with the replenishment hopper h. On the other hand, the driving device D is driven to rotate the transport cable 14 along the feeding pipeline P. Then, the feed is transported in the direction of the arrow X through the feeding pipeline P by the transport disk 14a of the transport cable 14, and when it reaches directly above each feeder B, it sequentially falls through the drop pipe 13, and each feeder B is supplied to B.

  In the illustrated feeding pipeline P, the transport pipe 11 is connected by the joint pipe 10 at the installation position of each feeder B as described above, and the drop pipe 13 is connected to the joint pipe 10 and suspended. Yes. A specific configuration of this pipe connection structure will be described below.

  As shown in FIG. 1, the joint pipe 10 of the illustrated example is integrally formed with a pipe connecting portion 10a at both ends and a feed dropping pipe portion 10b between the pipe connecting portions 10a as shown in FIG. It is formed into a round hollow short tube. In particular, the pipe connecting portion 10a is formed in a circular tubular shape whose inner diameter is matched with the outer diameter of the transport pipe 11 and is one step larger in diameter than the feed dropping pipe portion 10b. On the other hand, the feed dropping pipe portion 10b has a substantially same outer diameter as the transport pipe 11, and is formed by arranging a plurality of feed feeding ports 15, 16, 17 having different diameters in the circumferential direction. The feed feeding ports 15, 16, and 17 are each formed in an elliptical shape with different diameters depending on the feed supply amount to be fed from the feeding pipeline P to each feeder B. For example, as shown in FIG. 2, for example, three kinds of feed feeding ports are formed, differently from a large hole 15 for feeding a large amount of feed, a middle hole 16 for supplying a medium amount, and a small hole 17 for supplying a small amount. .

  Accordingly, when the joint pipe 10 formed in such a shape is connected to the transport pipe 11 as shown by a chain line in FIG. 1, when the end 11a is inserted into the pipe joint 10a, the joint pipe 10 is inserted into the pipe joint 10a. 11 end 11a is press-fitted and is turnably and liquid-tightly fitted.

  Furthermore, the illustrated joint pipe 10 has a configuration in which a pair of connecting brackets 20 and 20 for connecting the drop pipe 13 to the feed dropping pipe portion 10b and a shutter 25 for opening and closing the feed feeding ports 15, 16, and 17 are attached. Yes. The connecting brackets 20 and 20 have a semicircular pipe shape corresponding to the outer shape of the lower dropping portion 20a having a semicircular pipe shape according to the outer shape of the drop pipe 13 and the feed dropping pipe portion 10b of the joint pipe 10. And an upper covering portion 20b. A wire insertion hole 21 is provided in the upper covering portion 20b. The shutter 25 is bent into a semicircular pipe shape according to the outer shape of the feed dropping pipe portion 10b, and a wire latching portion 25a is provided on one side edge.

  And as shown in FIG. 3, the shutter 25 which tied the wire 26 for opening and closing to the wire latching | locking part 25a is slidably fitted to the joint pipe 10 on the outer peripheral surface of the feed dropping pipe part 10b. Then, with both ends of the opening / closing operation wire 26 passed through the wire insertion hole 21 and pulled out to the outside, the upper covering portion 20b of the connecting brackets 20 and 20 is covered with the feed dropping pipe portion 10b, and the feed feeding port 15 Select one of 16 and 17 and cover the lower covering portion 20a on the upper end portion 13a of the drop pipe 13 in a state where, for example, the large hole feed feeding port 15 communicates with the feed dropping port 30 of the drop pipe 13. And screw. Then, as shown in FIG. 4, the joint pipe 10 and the drop pipe 13 are connected and assembled in a T shape.

  In this joint pipe 10, as shown by an arrow in FIG. 3, the opening / closing operation wire 26 is pulled from the outside to rotate the shutter 21, and if necessary, is now in communication with the feed drop port 30 of the drop pipe 13. For example, a large-hole feed feeding port 15 is opened and closed so that feed feeding from the feeding pipeline P to the feeder B can be controlled. At this time, the shutter 21 is in a rotational position where the remaining feed feed ports 16 and 17 that are not used are closed, and the feed is prevented from leaking from the joint pipe 10.

  Now, when constructing the feeding pipeline P by connecting the transport pipe 11 using the joint pipe 10 having the above-described configuration, the transport pipe 11 is connected to the feeder at the work site of the pig house as necessary. The joint pipe 10 and the drop pipe 13 are connected and assembled in a T shape as described above. Thereafter, according to the installation layout of the feeder B, a necessary number of the transport pipes 11 are press-fitted into the pipe connecting portions 10a of the joint pipes 10 as shown in FIG. Then, simply by fitting the end portion 11a to the pipe connecting portion 10a, the many transport pipes 11 are connected one after another, and the desired feeding pipeline P is easily assembled accordingly.

  On the other hand, when it is necessary to adjust the amount of feed to be fed to the feeder B over time, the corresponding joint pipe 10 is rotated as it is with respect to the transport pipe 11 on the feeder B that needs to be adjusted. One of the feed feed ports 15, 16, and 17 is selected according to the desired feed supply amount to be changed, and the feed feed port having the selected hole size is communicated with the feed drop port 30 of the drop pipe 13.

  By the way, in the illustrated embodiment described above, the feed dropping pipe portion 10b of the joint pipe 10 is provided with three feed feeding ports 15, 16, 17 having different diameters. Two or four or more feed feeding ports may be provided in accordance with the difference in feed supply amount.

  In the illustrated embodiment described above, an example in which the joint pipe 10 is integrally formed of a resin material has been shown. However, the joint pipe of the present invention is formed by press-molding a plurality of feed feeding ports using, for example, a metal plate material. Further, it may be formed into a pipe shape having an enlarged diameter pipe connecting portion and a feed dropping pipe portion.

  Furthermore, in the present invention, the joint pipe 10 has a pipe connecting portion 10a that connects the conveying pipe 11 with an enlarged diameter, a step is formed between the joint pipe 10 and the conveying pipe 11 side, and the end portion of the conveying pipe 11 is placed in the pipe connecting portion 10a. 11a is press-fitted and liquid-tightly fitted, so that it prevents water and the like from entering when disinfecting and cleaning the feeding pipeline P, thereby causing clogging of the transport pipe as in the past. Generation of troublesome problems can be prevented. In this case, a waterproof tape or the like may be wound between the pipe connecting portion 10a and the transport pipe 11 to take a measure for making the waterproof property more complete.

  In the present invention, depending on the user's preference, one or both of the pipe connecting portions 10b and 10b at both ends may be cut, and the cut side may be connected to the transport pipe with an appropriate pipe joint material. The use of joint pipes is not excluded.
