Description

  In the direct sowing cultivation in which the seed pods are directly sown in paddy fields to cultivate paddy rice, the seed pods sown by direct sowing are prevented from being damaged by birds such as being sown by birds. The present invention relates to a seed vat coating processing apparatus for performing coating processing with a mineral powder in advance.

  As a means to prevent seed sowing seeded by direct sowing from being damaged by birds, the seed sowing seed is sprinkled with mineral powder prepared by adding calcined gypsum powder to iron powder, and added to it. It is effective to apply a mineral coating treatment to the seed pods by kneading and binding the mineral powder with iron oxide (rust) resulting from the oxidation of the minerals produced by the water and condensing it on the peripheral surface of the seed pods. It is known that

  When coating this seed cake with minerals, when the mineral powder, which is sprinkled and sprinkled on the seed cake, is condensed by binding with iron oxide (rust) formed by oxidation of the iron powder powder, If the heat of oxidation generated during oxidation is not sufficiently dissipated, the heat of oxidation will accumulate in the layer of mineral powder that has been applied to the seed pods, raising the temperature of the seed pods and causing germination problems. In the process of solidifying the mineral powder adhered to the seed pod, the coating treatment with the seed pod mineral is carried out by adding the mineral powder to the peripheral surface of the seed cocoon and condensing the mineral powder. It is also known that it is necessary to keep the soot seed spread in a thin layer so that the heat of oxidation is sufficiently dissipated.

  Then, in order to make the seed pods to which the hydrolyzed mineral powder adheres into a diffused state, prepare a shallow flat box-like container, and put the seed pods to which the mineral powder is attached to this. Then, the sample is leveled and spread so as to spread thinly on the upper surface of the floor plate of the container, and left in this state for several days to one week. When the mineral powder has been consolidated, Attempts have also been made to move to a bag.

  Furthermore, as a container for holding the seed pods with the mineral powder adhered, the seedling box (seedling box) that is usually used to grow soil seedlings used in rice transplanters is used as it is. When it can be used, and when the seedling box used to grow seedling seedlings for rice transplanters is used as a container for diffusing seed pods with mineral powder, the seedling seedlings are grown in this seedling box. Seed seedlings with mineral powder adhered to the seedling box by using the equipment and equipment of the earthing machine, which is configured so that the floor soil can be fed equally. Such a technical means has been tried.

  Next, the construction of an earthing machine used as a means for feeding the seed pod with the mineral powder attached thereto into a seedling box used as a container will be described with reference to FIGS. 1 and 2, A indicates the entire earthing machine, and 1 indicates a pedestal that is a main frame of the earthing machine A. The gantry 1 is a gantry that is assembled in the form of a square frame or a ladder that is long in the front-rear direction by the left and right girder members 10a that are long in the front-rear direction and the short horizontal beam 10b that is spanned between the left and right girder members 10a and the girder member 10a. The frame 10 and the supporting leg 11 assembled on the lower surface side of the frame 10 are configured in a table-top shape that is long in the front and rear direction. In addition, the member indicated by a chain line in the figure and attached with the symbol B indicates a seedling box to which floor soil is to be thrown in by the earthing machine A, and on the upper surface of the frame 10 of the earthing machine A, It shows a state of being mounted on a part close to the front end side (right end side in the figure). The seedling box B is a shallow flat box-like container composed of a surrounding wall board B1 and a floor board B2, and a handle-like edge B3 projecting outward from the upper end of the wall board B1 is provided at the front and rear ends. It is provided.

  The seedling box B mounted on the front end side of the underframe 10 is placed between the left and right girders 10a on the upper surface side of the underframe 10 on the rear end side of the underframe 10. A conveyance path W for conveying the seedling box is formed in a shallow channel shape into which the bottom of the seedling box B is fitted. The floor surface of the transport path W is equipped with a transport conveyor C that transports the seedling box B mounted on the front end portion of the upper surface of the frame 10 to the rear along the transport path W.

  The transfer conveyor C is supported at the front end portion (right end portion in the drawing) of the inner cavity of the frame 10 so as to be supported between the left and right beam members 10a and the beam member 10a. In addition, floating pulleys 21 and 21 that are pivotally supported on the left and right ends of the support shaft 20 and the intermediate shaft before and after the underframe 10 are supported between the left and right girders 10a and 10a. A drive shaft 22 to be supported, a drive pulley 23 to be supported on the drive shaft 22, and an endless belt 24 wound around the drive pulley 23 and an idle pulley 21 to be supported on the support shaft 20. Then, by driving and rotating the drive shaft 22 described above, the endless transport belt 24 rotates as shown by the thin line arrow in FIG. Transport box B toward the front and rear intermediate parts of underframe 10 Transport conveyor front half C ′, a second support shaft 25 that can be supported between the left and right girders 10 a and 10 a at the rear end portion of the frame 10, and left and right end portions of the second support shaft 25. The second idler pulleys 26 and 26 that can be pivotally supported by the first and second drive pulleys 26 and 26, and the second drive that is pivotally supported in parallel with the drive pulley 23 that is pivotally supported by the drive shaft 22 on the drive shaft 22 of the first half of the conveyor. A second conveyor belt looped endlessly between the pulley 27 and the second driving pulley 27 and a second idler pulley 26 pivotally supported on a support shaft 25 supported on the rear end side of the frame 10. When the first half of the conveyor is driven and rotated, the seedling box B is driven at the same time to convey the seedling box B from the front and rear intermediate portions of the frame 10 to the rear end side of the frame 10. It consists of the second half C ″ of the conveyor.

  The transport conveyor C has its drive shaft 22 positioned on one side of the left and right sides of the frame 10 and rotated by a motor M mounted and mounted in a conductor housing 4 mounted on the mount 1. The shaft is connected to the shaft through an appropriate transmission mechanism, and when the motor M is operated, the transfer operation is started, and when the motor M is stopped, the transfer operation is stopped. . The motor M has a main switch (not shown) connected to a control circuit (not shown) for controlling on / off of the drive of the motor M, and is attached to the outer surface of the conductor housing 4. By switching operation by manual operation of the switch lever 41, driving is started by closing the control circuit by turning it on, and by driving the main switch lever 41 to the off position, the main switch is turned off. The drive is stopped by opening the control circuit. Thus, the transfer conveyor C starts the transfer operation by operating the main switch lever 41 to the ON position and starts the operation of the motor M, and operates the main switch lever 41 to the OFF position to operate the motor M. The conveyance operation is stopped by stopping the operation.

  Reference numeral 2 denotes a hopper for storing the bed soil to be supplied into the seedling box B. The hopper 2 is located above the intermediate portion in the front-rear direction (left-right direction in the figure) of the underframe 10. It is assembled and supported on the upper surface side of the square frame-shaped assembly seat plate 12 that can be mounted at a position having a distance dimension approximately several times the height dimension. The bottom of the hopper 2 is opened as a lower opening 2a having a shape corresponding to a frame hole 13 formed inside the square frame-shaped assembly seat plate 12, and the lower opening 2a The communication is connected to the frame hole 13 of the seating plate 12.

  An idler roller 30 and a drive roller 31 are axially supported in parallel on the lower surface side of the assembly seat plate 12 so as to be opposed to each other in the front-rear direction. An endless transport belt 32 is wound around, and the upper surface side of the transport belt 32 on the upper rotation side is connected to the lower opening 2a of the hopper 2 through the frame hole 13 of the assembly seat plate 12. And communicates with each other to perform the function of the bottom wall of the hopper 2.

  The transport belt 32 is configured such that the rotation shaft of the drive roller 31 is connected to the rotation shaft of the motor M mounted in the above-described conductor housing 4 via an appropriate conduction mechanism provided in the conductor housing 4. As the drive roller 31 is driven and rotated by the motor M and rotates, the upper peripheral surface side operates so as to rotate from the rear to the front as indicated by the thin line arrows in FIG. By this operation, the floor soil in the hopper 2 supported on the upper surface of the transport belt 32 is fed out from the feed port 33 formed on the front edge side of the lower mouth 2a of the hopper 2, and the transport belt 32 , Discharged at the discharge port Y formed on the outer peripheral surface side of the circulation part at the terminal end side in the transport direction, dropped and put into a seedling box B mounted on the transport conveyor C mounted and mounted on the underframe 10 The feeding conveyor D to be damped is constituted.

  A shutter plate 34 is pivotally supported on the front surface of the delivery port 33 so as to freely rotate back and forth, and is a shutter plate that opens and closes the delivery port 33, and is rotated toward a posture in which it vertically hangs down by its own weight. When the floor soil is fed out from the feed outlet 33 by the operation of the feed conveyor D, the floor soil is turned forward by the feed pressure of the floor soil to open the feed outlet 33, and the floor soil is fed out. While permitting, the operation of the backward rotation by its own weight suppresses the upper surface side of the flow of the floor soil that is fed out, restricts the feeding amount to a certain amount, and when the operation of the feeding conveyor D stops, the restoring operation by its own weight It functions to close the delivery port 33 with power.

  Thus, the feeding conveyor D and the conveying conveyor C assembled to the underframe 10 are respectively driven by the operation of the motor M provided in the conductor housing 4 to feed the floor soil, as described above. Since the transfer operation for transferring the seedling box B is controlled, the main switch lever 41 assembled and installed on the outer surface of the conductor housing 4 is operated to be turned on, and the motor M Are started, both the conveyor C and the feeding conveyor D start operating. In the feeding conveyor D, the floor soil put in the hopper 2 is continuously fed out from the feeding outlet 33. In the transfer conveyor C, the transfer operation for transferring the seedling box B is continuously performed.

  From this, if the earth-moving machine A supplies the seedling box B to the upper surface of the front end side (right end side in the figure) of the underframe 10, the seedling box B is moved back on the underframe 10 by the transfer conveyor C. While passing toward the end side and passing under the feed outlet 33 of the feed conveyor D that continuously feeds the floor soil, the supply of the floor soil fed from the feed conveyor D is received, Since the floor soil is loaded in the seedling box B, the seedling box B is transported to the rear end side of the frame 10, so that the empty seedling box B is even supplied to the front end side of the upper surface of the frame 10. Then, the floor soil is automatically charged into the box and can be taken out at the rear end of the underframe 10 as the seedling box B after the loading of the floor soil. An efficient earthing machine is constructed as a means to load floor soil for growing.

  The earth-moving machine A configured in this manner is charged with seed powder that has been subjected to coating treatment by hydrating and adhering mineral powder into the hopper 2, and coating treatment with mineral powder. The seedling box B was used as a container for receiving the seed pods subjected to the treatment in a diffused state, and the seedling box B was placed on the front end side of the upper surface of the underframe 10 (the start end side in the transport direction of the transport conveyor C). If it is operated in the state, the seeds thrown into the hopper 2 are sequentially fed out from the feed outlet 33 by the operation of the feed conveyor D, and the end of the revolving part in the transport direction of the transport belt 32 is At the discharge port Y formed by the outer peripheral surface, it is discharged into free space and falls downward due to natural flow. And the seedling box B which moves this seed pod which falls by the action | operation of the conveyance conveyor C is from the part of the front end side (front end side in the moving direction of the seedling box B) on the upper surface of the floor board B2 in the inside. Then, while reaching the rear end side portion of the upper surface of the floor board B2, the receiving places are sequentially changed, and the received seed potatoes are spread on the floor board B2. Accordingly, the seed coating apparatus is configured.

  The soot coating apparatus configured in this manner is charged with the soot that has been subjected to the process of hydrolyzing and adhering the mineral powder into the hopper 2 of the above-mentioned earthing machine A. The seedling box B is used as a container for completing the coating process with the mineral powder by keeping the seed pods subjected to the mineral adhesion treatment in a diffused state so as to be fed out from the delivery outlet 33 by operation. This is supplied onto the underframe 10, and while the seedling box B passes under the feeding outlet 33, the seed pod that is fed out from the feeding outlet 33 and falls is added to the seedling box. B is a means for accepting while changing the receiving part sequentially from the front end part to the rear end part of the floor board B2 in B, and holding it in a diffused state. Use as is In this method, the seed heat treated with the mineral powder adhering to the mineral powder is sufficiently coated with the mineral powder adhering to the seed soot to dissipate the heat of oxidation that occurs when the iron powder is oxidized. In order to prevent this from happening, it is a means that can be efficiently performed without taking time and effort to put it in a container and make it diffuse.

  However, the coating processing means for the soot seed configured using the earthing machine is such that the conveying conveyor C and the feeding conveyor D of the earthing machine are continuously operated during operation. Even when the seedling box B does not exist below the feeding outlet 33 of the feeding conveyor D because the supply of the seedling box B to the upper surface is interrupted, the feeding conveyor D is continuously operated, so that There is a problem that a large amount of loss occurs in the seed pod introduced into the seedling box B by continuing to feed out the seed pod.

  The problem of this loss is a problem that inevitably arises when the earth-moving machine A is used for the work of loading the soil for raising seedlings into the original seedling box B. Because the floor soil to be obtained can be obtained at a low cost, it was allowed by not reaching a loss.

  However, when the finishing means of the seed coat coating process is configured using an earthing machine, it is fed out from the feed outlet 33 by the operation of the feed conveyor D, dropped, and supplied to the moving seedling box B. What goes on is the seed pod that has been subjected to adhesion treatment by adding mineral powder, and it is expensive and expensive, so loss is not allowed and becomes a problem to be solved.

Therefore, as measures against this, the following means have been tried.
As shown in FIG. 3, this means is provided in the middle of the conveying path W formed on the upper surface side of the underframe 10 so as to guide the seedling box B conveyed by the operation of the conveying conveyor C. The operating arm r is brought into contact with the bottom of the seedling box B moving on the conveyance path W at a position located below the discharge port Y formed by the outer peripheral surface of the circulation section on the conveyance direction end side of the conveyance belt 32. When the contact is released, the limit arm LS is installed to return to the OFF position and operate OFF, and this limit switch LS is turned ON / OFF. When the limit switch LS is activated, the driving circuit of the feeding conveyor D is closed to start the operation of the feeding conveyor D. When the limit switch LS is activated, the driving circuit is opened to open the feeding circuit. A means for configuring by connecting to stop the operation of the A D.

  With this configuration, when the front end portion of the seedling box B traveling on the transport path W reaches a portion of the transport path W located below the discharge port Y of the feeding conveyor D, the upper half of FIG. As shown on the side, the front end of the bottom of the seedling box B abuts on the operating arm r of the limit switch LS, and pressing this turns on the limit switch LS, and the limit switch LS is turned on, The driving circuit of the motor M is closed and the feeding operation of the feeding conveyor D is started. By the feeding operation of the feeding conveyor D, the seeds in the hopper 2 are fed from the feeding port 33 and fall at the discharge port Y, and are conveyed. It will be in the state supplied with respect to the site | part located under the discharge port Y of the seedling box B with respect to the seedling box B on the path W.

  As the seedling box B continues to advance, the part located below the discharge port Y moves from the front end part of the seedling box B toward the rear end part in sequence. However, during the progress of the seedling box B, the limit switch LS was turned on because its operating arm r was kept pressed against the bottom surface of the bottom of the seedling box B. The state is continued, and the operation for feeding out the seeds of the feeding conveyor D is continued.

  When the seedling box B further advances and passes the lower position of the discharge port Y and the rear end of the bottom of the seedling box B passes the limit switch LS, the limit switch as shown in the lower half of FIG. The operating arm r of the LS is removed from the rear end of the bottom of the seedling box B, and the contact is released to restore the OFF position. The driving circuit is opened to stop the operation of the feeding conveyor D. Stop feeding.

  In this way, by controlling the operation of the feeding conveyor D, the feeding conveyor D can be used only when the seedling box B conveyed and moved by the feeding conveyor C is located below the discharge port Y of the feeding conveyor D. Is operated to feed out bed soil or seed pods and prevent seed pod loss caused by feeding out seed pods where seedling box B does not exist.

  As shown in the upper half of FIG. 3, this means is a seedling box B that moves along the transport path W to a position located below the discharge port Y of the feeding conveyor D in the middle of the transport path W. When the limit switch LS is installed, the operation arm r is pushed into the ON operation position by the contact with the front end portion of the bottom part of the product and is turned ON, and the operation of the feeding conveyor D is started to start the feeding of the seeds. When the arm r is pushed into the ON operation position, it is necessary for the seed pod that is fed out by the feeding operation of the feeding conveyor D that has started to be operated and discharged from the discharge port Y to reach the floor surface of the seedling box B. Expecting the time, set the limit switch LS to a position slightly before the discharge port Y, and install it as shown in the upper half of FIG. Ah r is turned on by contact with the seedling box B moving on the conveyance path W, and the feeding conveyor D starts feeding operation, and is thereby discharged at the discharge port Y fed out from the feeding port 33. When the seed pods are dropped and supplied to the seedling box B on the transport path W, the supply to the floor surface of the floor board B2 in the seedling box B of the seed potato is supplied to the floor surface of the floor board B2. It is performed from the position at the front end side, so that seed pods can be supplied to the entire floor surface without generating a blank part where seed pods do not exist on the front end side of the floor surface of seedling box B. Become.

  However, as described above, the means for setting the installation position and controlling the on / off operation of the feeding conveyor D that feeds the seeds by the limit switch LS set on the conveyance path W includes a floor surface inside the seedling box B. The operating arm r of the limit switch LS continues to be in contact with the bottom of the seedling box B even if the seedling box B has moved until the rear end occupies a position below the discharge port Y of the feeding conveyor D. The operation of the feeding conveyor D is not turned off, the seed potatoes continue to be fed, and the seedling box B moves to the position where the rear edge B3 of the seedling box B is located below the discharge port Y. When the arm r is detached from the bottom of the seedling box B, the operation of the feeding conveyor D is turned off and the feeding of the seed pod is stopped. As shown in the lower half side of FIG. Seeds falling from Y and falling Fell on the upper surface of the edge portion B3 of the box B, its edge seeds fell on B3 is a problem to generate a loss of seeds by flowing out of the seedling box B comes happening.

  When this limit switch LS is turned off by the passage of the seedling box B to stop the feeding of the seed seeds, the seed seeds generated on the rear end side of the seedling box B escape to the outside of the seedling box B and The phenomenon that causes the loss is that the operating point p1 of the operating arm r of the limit switch LS that is off is at the tip of the operating arm r as shown in the lower half of FIG. Since the operating point p2 that is turned on is in the middle part of the operating arm r as shown in the upper half of FIG. 3, the seeding point is higher than the operating point p2 that is turned on. This is caused by shifting in the traveling direction of the box B, but the operating arm r keeps a state of continuously contacting the uneven bottom surface of the seedling box B passing therethrough. For this purpose, it must be long and the movable range in the vertical direction should be increased. Since, because slippage of the operating point p1 come really occurs, the phenomenon of escape of seeds produced on the rear end side of the seedling box B is a phenomenon coming inevitably occur.

  The phenomenon that the seed pod escapes from the seedling box B on the rear end side of the seedling box B is caused by shifting the installation position of the limit switch LS toward the lower side of the discharge port Y of the feeding conveyor D, When the rear end of the floor plate B2 in B has reached the position below the discharge port Y, it can be eliminated by controlling it to turn off and stop the sowing of seeds. When the installation position of the switch LS is set and installed, the operation point p2 that activates the operation arm r is also moved to a position shifted forward, so that the seedling box B reaches a position below the discharge port Y. Before, the front end portion of the bottom of the seedling box B comes into contact with the operating arm r, and this is turned on, and the operation of the feeding conveyor D is started. In front of the front of the seedling box B So falling down to the range of the upper surface of the side edge portion B3, so that escape of the seeds at the front end of the seedling box B is arise.

  Therefore, when supplying the seed pods released from the discharge port Y and falling to the inside of the seedling box B that passes below the discharge port Y, this means has a front end side and a rear side of the seedling box B. There is a problem of causing escape loss of seeds on either the end side.

  The problem to be solved in the present invention is to mount a seedling box moving on the transport path W above the intermediate portion in the continuous direction of the transport path W by the transport conveyor C incorporated in the transport path W. Using the earthing machine in a form in which the floor soil in the hopper 2 is fed by the feeding conveyor C provided on the lower surface side of the lower mouth of the hopper 2, dropped from the discharge port Y, and thrown into the seedling box, Limit that the finishing device of the coating process is provided on the conveyance path W when the finishing device that finishes the coating process by diffusing the seeds coated with a mineral film on the peripheral surface to the floor of the container When the switch LS is turned on by contact with the seedling box B moving on the conveyance path W, the seed hopper is fed out from the hopper 2 and discharged at the discharge port Y by the operation of the feeding conveyor D which starts the operation. The seed vase is supplied to the seedling box B by being dropped and dropped onto the seedling box B on the conveyance path W. The seed vase does not escape to the outside, and the top surface of the floor plate B2 of the seedling box B that accepts the falling seed vat is formed without generating a blank portion where no seed vat exists. There is in point to do.

  The present invention has been made in order to solve the above-described problem, but the operation of the feeding conveyor D is switched between the operation start and the operation stop by the above-described operation of detecting the presence or absence of the seedling box B by the limit switch LS. Thus, when the seed pod fed out by the feeding conveyor D and supplied into the seedling box B is prevented from falling off the front and rear seedling boxes B of the seedling box B, There is a problem that seed pods fall on the upper surface of one of the front edge side and the rear edge side edge of seedling box B, causing a loss to escape out of seedling box B. Detecting the presence of the seedling box B at a predetermined position in the transport path W for the control to turn on the operation of the feeding conveyor D, and the transport for the control to turn off the operation of the feeding conveyor D The seedling box B does not exist at the predetermined position on the road W It is conceived that the detection operation is caused by the on / off operation of one limit switch LS, and from this, the presence / absence of the seedling box B at a predetermined position on the conveyance path W is detected. Two limit switches are used for the limit switch installed in the transport path W so that the seedling box B is detected in one limit switch, and the seedling box B is set in the other limit switch. This is based on the idea that it can be solved by performing the detection operation of the absence.

  When the limit switch LS for detecting the presence or absence of the seedling box B is installed on the transport path W, the limit switch LS installs two limit switches, a first limit switch LS1 and a second limit switch LS2. For example, as shown in FIG. 4, these first and second limit switches are arranged at a position located below the discharge port Y of the feeding conveyor D in the first limit switch LS1. The second limit switch LS2 is installed at a position slightly deviated from the installation position of the first limit switch LS1, and thereby the first and second limit switches LS1 are installed. -LS2 is arranged in the conveyance path W so as to be mixed back and forth in the conveyance direction of the seedling box B on the conveyance path W. The first and second limit switches LS1 and LS2 are connected to a control circuit of a driving motor M that controls on / off of the operation of the feeding conveyor D, respectively. Connect in series on the control circuit. As a result, the control circuit is closed when both the first and second limit switches are turned on, and the control circuit is opened when either one of the limit switches is turned off. To be done.

  As described above, when the two limit switches LS1 and LS2 are arranged on the transport path W, when the seedling box B does not exist on the transport path W, both the first and second limit switches LS1 and LS2 are off. The control circuit is in the “open” state. Accordingly, the feeding conveyor D is in a state where the operation is stopped.

  From this state, when the seedling box B is supplied to the transport path W and the seedling box B moves, first, it comes into contact with the second limit switch LS2 located in front of the first limit switch LS1, Turn this on. At this time, the control circuit is in a state where only one limit switch of the first and second limit switches LS1 and LS2 connected in series is turned on and the other limit switch is turned off. Therefore, it is held in the “open” state. Accordingly, the feeding conveyor D is maintained in a state where the operation is stopped.

  When the seedling box B further moves, in the transport direction of the transport path W, the first limit switch LS1 that occupies the second limit switch LS2 comes into contact with the second limit switch LS2, and the switch LS1 is turned on. At this time, the second limit switch LS2 that was previously turned on is in the state of being turned on because its operating arm r continues to contact the bottom of the seedling box B that is moving. The ON operation of the first limit switch performed in this state means that the two switches arranged in series and connected to the control circuit are both turned ON, the control circuit is “closed”, and the feeding conveyor D Start the operation. Accordingly, the first limit switch LS1 functions to perform a detection operation for detecting the presence of the seedling box B among the detection operations for detecting the presence or absence of the seedling box B.

  When the movement of the seedling box B further proceeds and moves to a place beyond the first and second limit switches installed below the discharge port Y of the feeding conveyor D, the bottom of the seedling box B and the first When the contact with the second limit switch is released, the first and second limit switches are turned off, but the second limit switch LS2 is in front of the first limit switch LS1. Since the second limit switch LS2 is turned off first, the first limit switch LS1 is turned off after the second limit switch LS2 is turned off. Since the second limit switch LS2 is turned off, even if the first limit switch LS1 is turned on, the control circuit for on / off control of the driving of the feeding conveyor D is "open". Stop the operation of D. Accordingly, the second limit switch LS2 detects that the seedling box B does not exist in the detection operation for detecting the presence or absence of the seedling box B for controlling on / off of the operation of the feeding conveyor D. It becomes a limit switch that functions to operate.

In this way, two limit switches are used as limit switches for detecting the presence / absence of two seedling boxes B, and the detection operation of the presence of seedling box B is performed on one of the limit switches. If the detection operation that the seedling box B does not exist in the other limit switch is performed, the installation position of the other limit switch that detects the absence of the seedling box B can be selected and set as desired. When the operation of the feeding conveyor D is stopped, the portion of the seedling box moving on the transport path W that occupies the lower side of the discharge port Y of the feeding conveyor D can be set at a desired position. When the operation of the feeding conveyor D is stopped, the above-mentioned problems caused by the falling seed pods falling and accumulating on the upper surface of the edge B3 of the seedling box B can be solved. It made.
And from this, in the present invention, as means for solving the above-mentioned problems,
On the upper surface side of the frame 10 of the gantry 1 formed in a long table shape in front and rear, the seedling box B is actuated by driving by a motor M assembled to the gantry 1 and the seedling box B is directed from the front end side to the rear end side Equipped with a conveying conveyor C for conveying and a conveying path W for guiding the seedling box B conveyed by the conveying conveyor C, the upper position of the intermediate portion in the longitudinal direction of the underframe 10 opens downward to the bottom surface. The hopper 2 provided with the lower opening 2a is positioned at a height position that is a distance of several times the height of the seedling box B from the conveyance path W on the upper surface of the frame 10 and is mounted on the gantry 1 Mounted below the lower surface side of the hopper 2 is a driving conveyor D that is driven by a motor M mounted on the gantry 1 to feed forward the seeds loaded into the hopper 2, and is mounted on the conveyor. In the middle of the continuous direction of the path W, located below the discharge port Y of the feeding conveyor D The portion that is turned on is activated by contact of the operating arm with the bottom surface of the bottom of the seedling box B moving along the conveyance path W, and is restored to be turned off by releasing the contact with the bottom surface of the bottom of the seedling box B. The first limit switch LS1 is arranged and installed, and the second limit switch LS2 is arranged and installed at a position shifted from the installation position of the limit switch LS1, and these switches LS1 and LS2 are installed. To the control circuit of the motor M that drives the feeding conveyor D, the control circuit is closed by the ON operation to start the operation of the feeding conveyor D, and the control circuit is opened by the OFF operation to operate the feeding conveyor D. A finishing device for coating seeds using an earthing machine arranged in series on the control circuit and connected to the control circuit so as to stop.
Is to raise.
In addition, as described above, the seed coat coating processing apparatus using the earthing machine according to the present invention is configured so that when the operation of the feeding conveyor D is on / off controlled, the operation of the transport conveyor C that transports the seedling box B is performed. Even if they are turned on / off together, the operation / function for controlling on / off of the operation of the feeding conveyor D by the operation of detecting the presence / absence of the seedling box B by the two limit switches LS1, LS2 is not affected. As a result of the trial, it has been found that the motor M that drives the feeding conveyor D and the motor control circuit are shared with the motor that drives the conveyor C and the motor control circuit. If the motor can drive both the feeding conveyor D and the conveying conveyor C, the driving means by the motor of the feeding conveyor D and the conveying conveyor C From what has been conceived to be half the production costs,

The feeding conveyors mounted on the gantry 1 are respectively shown.

  The gantry 1, the hopper 2, the transfer conveyor C, and the feeding conveyor D are configured in the same manner as those provided in the conventional earthing machine A described and shown in FIGS. 1 and 2. Since these are the same, the same reference numerals are given to the same components.

  The earthing machine indicated by the symbol A has the same configuration as the conventional earthing machine shown in FIGS. Further, the gantry indicated by reference numeral 1 is configured as a table by attaching a support leg 11 to the lower surface side of a frame 10 formed in a square frame shape or a ladder shape that is long in the front-rear direction.

  The conveyor C installed on the upper surface side of the frame 10 of the gantry 1 is composed of a first half C ′ of the conveyor and a second half C ″ of the conveyor. The first half C ′ of the conveyor is A support shaft 20 that is supported so as to be bridged between the left and right girders 10a and the girders 10a at the inner front end portion, and floating pulleys 21 and 21 that are supported by the left and right end portions of the support shaft 20; , A drive shaft 22 that is arranged at an intermediate portion before and after the frame 10 and is supported so as to be bridged between the left and right beams 10a and 10a, and a drive that is supported at the left and right ends of the drive shaft 22 The pulleys 23 and 23 and endless belts 24 and 24 wound around the pulleys 21 and 21 supported on the support shaft 20 are configured.

  In addition, the second half C ″ of the conveyer is disposed at the left and right sides of the second drive pulleys 27 and 27 assembled in parallel with the drive pulleys 23 and 23 on the drive shaft 22 and the rear end side portion of the frame 10. A second support shaft 25 that is supported so as to be bridged between the spar members 10a and 10a, second idle pulleys 26 and 26 that are assembled and supported on the second support shaft 25, and a second idle motion thereof. The second conveyor belts 28 and 28 are provided between the pulleys 26 and 26 and the second drive pulleys 27 and 27.

  The transport conveyor front half C ′ and the transport conveyor rear half C ″ share the drive shaft 22, so that the conductor housing 4 assembled on the left and right sides at the middle part before and after the frame 10. The motor M installed inside is operated, and the drive shaft 22 is driven and rotated via a transmission mechanism incorporated in the conductor housing 4 to rotate together. A seedling box B supplied to the front end side of the transport path W formed on the side is configured to transport the seedling box B along the transport path W toward the rear end side of the underframe 10.

  The hopper 2 has a square frame-shaped assembly seat that is assembled to the gantry 1 with the funnel-shaped bottom portion thereof being positioned at a position spaced above the upper surface of the framing frame 10 in the middle part before and after the framing frame 10. By mounting and supporting the plate 12, the base 1 is equipped. The bottom of the funnel-shaped bottom of the hopper 2 is opened as a lower opening 2a, and the lower opening 2a is a frame formed on the inner peripheral side of the square frame-shaped assembly seat plate 12. The upper surface of the turning portion on the upper peripheral surface side of the delivery conveyor D mounted on the lower surface side of the assembly seat plate 12 becomes the bottom surface of the hopper 2. It is like that.

  2b is a sieve net shelved in the hopper 2 and is formed by forming countless pores corresponding to the grain size of the seed plate by punching processing, and the coating material is attached to the peripheral surface. When the seed pods that have been lumped by kneading are put into the hopper 2 in the form of lumps and separated into single grain seeds by manual operation in the hopper 2, the seed pods separated into single grains are separated. Only functions to pass through the pores of the mesh and fall to the bottom of the hopper 2.

  33 is a feed outlet for feeding out the seeds thrown into the hopper 2, and is formed by cutting off the lower end portion of the front edge of the lower mouth 2a at the lower end portion of the peripheral wall of the hopper 2, By the operation, the seeds supported on the upper surface of the feeding conveyor D are carried forward and then fed out through the feeding port 33.

  The feeding conveyor D has an idler roller 30 and a driving roller 31 on the lower surface side of the assembly seat plate 12 and located below the front edge portion and the rear edge portion of the assembly seat plate 12. Each of the motors M is supported by a motor M mounted in a conductor housing 4 that is endlessly wound around the idler roller 30 and the drive roller 31 and is assembled to the left and right sides of the underframe 10. By driving the roller shaft of the drive roller 31 through the transmission mechanism G incorporated in the conductor housing 4, the upward rotation side is moved as shown by the thin line arrow in FIG. 10. It is configured to rotate forward and to feed out the seeds to be supported from the feed outlet 33.

  Reference numeral 34 denotes a shutter plate provided in front of the feeding port 33. The shutter plate is pivotally supported by the upper end portion by a support shaft so as to rotate back and forth, and rotated toward a vertical posture by its own weight. When the feeding conveyor D stops operating and the seeds are not fed out, the feeding conveyor 33 is rotated toward the closing position, and the feeding conveyor D is rotated to perform the feeding operation. When the seeds are fed out, they rotate forward to allow the seeds to be fed out, and the regenerative power due to their own weight suppresses the seeds that are fed out and regulates the feed amount to a constant level. It functions in the same manner as the shutter plate 34 of the conventional earthmoving machine A.

  LS1 is a first limit switch that is installed so as to detect the presence or absence of the seedling box B in the middle of the guide path provided in the underframe 10 so as to guide the seedling box B that is transported by the transport conveyor C. Similarly to the first limit switch LS1, LS2 is a second limit switch installed in the middle of the guide path of the seedling box B transported by the transport conveyor C.

These limit switches LS1 and LS2 are placed on the upper surface of the transfer conveyor C and their installation positions are shifted back and forth in the transfer direction of the transfer conveyor C as shown in the side view of FIG. When B is guided forward by the transport path W formed in the frame 10 and moved forward, the front end of the bottom of the seedling box B is first placed on the operating arm r of the second limit switch LS2 in the front position in the transport direction. by but abuts, said second limit switch LS2 performs detection operation, further, seedling box B is moved to the end direction of the conveying direction of the conveyor C, a first limit in the position after the transport direction by the front end of the bottom of Naebako B to actuating arm r switch LS1 abuts, said first limit switch LS1 is are to perform the detection operation.

  The installation location of the limit switches LS1 and LS2 in the middle of the conveyance path W is, as shown in the plan view of FIG. 10 provided at the right side end of the transfer path W of the seedling box B formed by the inner surfaces of the left and right girders 10a and 10a, and in the second limit switch LS2, the transfer of the seedling box B Although it is provided at the left side end of the path W, as described above, the seedling box B is supplied to the start end side (front end side) of the transfer conveyor C, and the first and second limit switches LS1 and LS2 are The first limit switch LS1 is detected when the second limit switch LS2 first detects the presence of the seedling box B, and then when the seedling box B moves further forward. Is seedling box B To detect the presence, it is sufficient so as to detect operation in two stages in accordance with rearward movement of the seedling box B, location is one or anywhere.

  Thus, the first and second limit switches LS1 and LS2 drive the operation of the conveyor C to stop the operation of the conveyor C by the detection operation that detects the presence of the seedling box. In this embodiment, as shown in the circuit diagram of FIG. 9, the control circuit U of the motor M for driving the conveyor C and the feeding conveyor D is turned on. The control circuit U is closed, the motor M is started to operate the transport conveyor C and the feeding conveyor D, the control circuit U is opened by the off operation, the rotation operation of the motor M is stopped, and the transport conveyor C And the limit switches LS1 and LS2 are connected to the control circuit U so as to stop the rotation operation of the feeding conveyor D. When allowed to, they are connected by allowed arranged in series. Thereby, the earth-moving machine A of this Example apparatus which implements the means of the present invention is configured such that the control of the operation of the transport conveyor C and the feeding conveyor D is configured as follows.

  When the main switch M.sw (which is normally mounted on the outer surface of the machine casing 4) for turning on / off the control circuit U of the motor M is held off, the control circuit U is opened. As a result, the motor M does not rotate, so that the conveyor C and the feeding conveyor D do not operate together and are held in a stopped state.

  Next, from the above state, when the main switch M · sw of the control circuit U of the motor M is switched on by manual operation and turned on, there is no supply of the seedling box B to the upper surface of the underframe 10. If the seed box B is not detected by the first and second limit switches LS1 and LS2, the first and second limit switches LS1 and LS2 are in the off state position. Since the control circuit U is opened, the motor M does not operate, and the transport conveyor C and the feed conveyor D are both held in a stopped state.

  Next, when the seedling box B is supplied to the front end side of the underframe 10 and mounted on the upper surface of the start end side of the transfer conveyor C as shown in FIG. However, since it is held in a stopped state for the above-described reason and does not perform the conveying action, the seedling box B does not move from the position where it is placed and continues to be located at that position. Accordingly, the first and second limit switches LS1 and LS2 do not perform the sensing operation of the seedling box B, and the transport conveyor C and the feed conveyor D continue to hold the stopped state.

  Next, when the seedling box B mounted on the upper surface on the front end side of the underframe 10 is pushed and moved forward in the transport direction of the transport conveyor C by manual operation, the seedling box B moves. The front end portion in the direction comes into contact with the first and second limit switches LS1 and LS2 in sequence to cause the switches LS1 and LS2 to perform a detection operation (ON operation). First, as shown in FIG. As shown in the figure, only the second limit switch LS2 positioned in front of the transport direction is caused to perform the detection operation.

  The first and second limit switches LS1 and LS2 are connected to the control circuit U and installed so as to close the control circuit U of the motor M by the detection operation (ON operation). However, since the second limit switch LS2 is turned on by the operation of detecting the seedling box B, the first limit switch LS1 that does not perform the detection operation is turned off because the control circuit U is connected in series. By being in the state, the control circuit U continues to be kept open. Accordingly, the transport conveyor C and the feeding conveyor D do not operate, and the seedling box B remains at the position where the second limit switch LS2 is detected.

  Next, when the seedling box B is further pushed forward from this state by manual operation, the front end side of the bottom surface of the seedling box B in the pushing direction is the first limit switch LS1 as shown in FIG. The first limit switch LS1 is caused to perform a detection operation to be turned on. At this time, since the bottom surface of the seedling box B is kept in contact with the second limit switch LS2, the second limit switch LS2 is held in an on state. From this, both the first and second limit switches LS1 and LS2 are turned on, and the control circuit U is closed, whereby the motor M is started, and the conveyor C and the feeding conveyor Both D begin to operate.

  Therefore, the 1st limit switch LS1 performs the operation | movement which detects presence of the seedling box B, and starts the operation | movement of the conveyance conveyor C and the delivery conveyor D. FIG. And the seedling box B is conveyed by the conveyor C which started operation | movement, and moves to the rear end side of the base frame 10 automatically, and is drawn | fed out from the inside of the hopper 2 by the feeding conveyor D which started operation | movement to this. The seed soup that is dropped falls and is put into a state (FIG. 13).

  Next, in the above-described state, the seedling box B which is transferred to the rear end side of the frame 10 by being transferred by the operation of the transfer conveyor C while being received in the seed pods supplied by the operation of the supply conveyor D is provided. As the movement proceeds to a position beyond the second limit switch LS2, as shown in FIG. 14, the second limit switch LS2 is detected by moving out of contact with the seedling box B. The operation is released and it is restored to the off state.

  When the second limit switch LS2 is turned off, the control circuit U is opened, and both the transport conveyor C and the feed conveyor D stop operating. Therefore, the seedling box B stops at the position where the rear end side exceeds the second limit switch LS2 in the state where the acceptance of the seed pod has been completed. However, the stop position of the seedling box B with respect to the first limit switch LS1 is The first limit switch LS1 is held in the on state by being in the position where the contact continues. That is, the second limit switch LS2 performs an operation of detecting that the seedling box B does not exist, and stops the operations of the feeding conveyor D and the transfer conveyor D. Then, the seedling box B holds the first limit switch LS1 in the ON state, and stops at a position beyond the second limit switch LS2 in a state where the acceptance of the seed pod has been completed ( FIG. 14).

Next, when the next seedling box B is supplied to the front end side (starting end side) of the frame 10 from this state, the supplied seedling box B is conveyed because the second limit switch LS2 is in an OFF state. When the conveyor C is in a stopped state, the conveyor C is held at the supplied position. Therefore, when the supplied seedling box B is pushed and moved toward the rear end side (terminal side) of the frame 10 by manual operation, the movement causes the front end of the seedling box B as described above with reference to FIG. When the part has advanced to a position where it comes into contact with the second limit switch LS2 , the contact causes the second limit switch LS2 to be turned on.

  At this time, since the first limit switch LS1 is in contact with the bottom of the front seedling box B and is in an on state, the second limit switch LS2 is turned on by the next seedling box B. The first and second limit switches LS1 and LS2 are both turned on, the control circuit U is opened, and both the conveyor C and the feeding conveyor D start operating.

  Therefore, the front seedling box B, which has been stopped in the state where the acceptance of the seed pods has been completed, moves toward the rear end side of the frame 10 by the transfer operation of the transfer conveyor C that has started the operation. The next seedling box B whose front end is in contact with the second limit switch LS2 and pushed to the position where the second limit switch LS2 is turned on is also transported by the transport conveyor C which has started to operate. As a result, the state automatically moves toward the rear end side of the underframe 10.

  Next, as a result of the operation in this state, the seedling box B in the preceding order is changed to the bottom surface (limit switch LS1) on the rear end side (the rear end side in the moving direction of the seedling box B and the right end side in the drawing). When the contact surface of LS2 with respect to the operating arm r) moves to a position where it escapes from the operating portion of the second limit switch LS2, the second limit switch LS2 is released from the detection operation for the seedling box B in the previous order. In this case, the front end of the bottom surface of the next seedling box B that moves together with the preceding seedling box B is the operating arm r of the second limit switch LS2. The second limit switch LS2 is held in an on state because the detection operation is performed by abutting on the second limit switch LS2. Therefore, the control circuit U is not opened and keeps the closed state, and the transport conveyor C and the feed conveyor D continue to operate.

  As a result, the front seedling box B that has finished accepting the seed potatoes moves toward the seedling box outlet on the rear end side of the underframe 10, and below the feeding conveyor D that feeds and drops the seed pods, The seedling box B is switched and positioned and moves backward while accepting the seed pods falling from the feeding conveyor D.

  Next, when the movement of the next seedling box B proceeds and the rear end of the bottom surface of the next seedling box B moves to a position beyond the operating arm r of the second limit switch LS2, the above-described front seedling box B is moved. Similar to the box B, the second limit switch LS2 is turned off to open the control circuit U, and the operations of both the transport conveyor C and the feed conveyor D are turned off.

  Accordingly, the seedling box B supplied to the next position is stopped when the reception of the seed pods fed from the hopper 2 by the feeding conveyor D is completed, and the feeding of the seed potatoes from the hopper 2 is stopped at the same time.

  In this state, the next seedling box B is supplied to the front end portion of the underframe 10 and the seedling box B is pushed out by manual operation and comes into contact with the second limit switch LS2. This is continued until the limit switch LS2 is turned on.

  FIG.15 and FIG.16 shows another Example, The FIG. 15 is the longitudinal cross-sectional side view of the whole Example same as the above, FIG. 16 is a vertical front view of an Example same as the above.

  In this embodiment, the seed pods dropped on the upper surface of the edge B3 on the front end side of the seedling box B with respect to the finishing apparatus in the seed candy coating process using the earthing machine of the first embodiment described above escapes out of the seedling box B. In order to prevent it from being lost and becoming lost grains, a sliding contact member E that collects seed pods dropped and accumulated on the upper surface of the edge B3 of the seedling box B, and a discharge port Y of the feeding conveyor D This is an example in which a side guide plate F that guides the seed pods falling from the inside of the upper edge of the edge B3 is assembled and added.

  Since the entire basic configuration and the constituent members other than the slidable contact member E and the side guide plate F to be added are the same as those in the first embodiment, the same reference numerals are used for the same slidable contact members.

It is supported by hanging by '.

  The sliding contact member E has a front end side of the seedling box B when the seedling box B that has been fed by the feeding conveyor D and receives seed seeds that has been dropped passes through the lower side of the sliding contact member E. The seed pods that have fallen and accumulated on the upper surface of the edge B3 of the sewage are swept into the seedling box B and recovered. Further, when the seedling box B is continuously supplied in a state in which the edge B3 on the front end side of the next seedling box B is brought into contact with the edge B3 on the rear end side, The seed pods dropped and deposited on the upper surface of the edge B3 on the end side are collected in the box of the next seedling box B together with the seed pods deposited on the upper surface of the edge B3 on the front end side of the next seedling box B. To function.

  In the side guide plate F, it is formed in an inclined plate shape in which the lower end side is inclined toward the left and right central portions of the transport path W at the left and right side positions of the transport path W below the discharge port Y of the feeding conveyor D. The seed potatoes that have been installed and mounted on the support machine frame F ′ assembled to the gantry 1 are released from the discharge port Y of the feeding conveyor D and fall outside the right and left sides of the seedling box B. It works to prevent it from escaping.

  FIG. 17 is a side view in which a main part of still another embodiment is cut vertically. This embodiment occupies the lower part of the discharge outlet Y of the delivery conveyor D in the middle of the conveyance path W in the means of the finishing device for the seed coat coating process using the earthing machine of the first and second embodiments. Two limit switches LS1 including a first limit switch LS1 arranged and installed at a position and a second limit switch LS2 arranged and installed at a position slightly shifted to the front of the limit switch LS1 -About 2nd limit switch LS2 provided in the position shifted ahead among LS2, it conveys the installation position with respect to the rear end part of the seedling box B of the priority order stopped on the conveyance path W. When the front end of the next-order seedling box B supplied on the road W and moved forward is abutted, the rear wall B1 of the previous-order seedling box B and the front wall B1 of the next-order seedling box B Corresponding to the distance formed between The distance is set to a position shifted forward from the first limit switch LS1, and by this, the seedling box B of the next rank is supplied and moved, so that it contacts the bottom of the seedling box B.
