[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pot seedling box cleaning apparatus for cleaning a pot seedling box that grows rice seedlings into adult seedlings.
[0002]
In the seedling box for growing rice seedlings, there is a pot hole that is molded into a flat box shape with a hard resin material, etc., and a pot hole that is formed into a small bowl shape with a resin material and has a smaller diameter at the bottom than the opening on the upper surface side. There is a pot seedling box for adult seedlings that is arranged in a plurality of vertical and horizontal directions and is formed of a soft resin material or the like so as to be curved.
[0003]
The pot seedling box cleaning apparatus according to the present invention is a pot seedling box cleaning apparatus for a pot seedling box for adult seedlings, in which pot holes to be described later are arranged vertically and horizontally.
[0004]
[Prior art]
As a conventional pot seedling box cleaning device, for example, as disclosed in JP 2000-316392 or JP-B-1-42647, a pot seedling box is forcibly sent to a cleaning unit by a seedling box transporting claw, and in a side view Both are known to wash the pot seedling box while curving it.

[Problems to be solved by the invention]
In the above-described technique, it is necessary to insert the pot seedling box into the cleaning unit inlet and transfer the seedling box transporting claw into the pot hole of the pot seedling box. Is always forcedly driven by a chain or the like, there is a problem that the operator has to adjust the insertion time of the pot seedling box in order for the seedling box transporting claw to be inserted into the pot hole in a timely manner, There was a problem that the pot seedling box was damaged depending on the insertion timing.
[0007]
In addition, the seedling box cleaning unit rubs the seedling box with the seedling box guide and transports it from the inlet side to the outlet side. Since the seedling box guide is provided in parallel with the long side of the pot seedling box and on a straight line, the seedling box guide is covered with the pot seedling box and cannot be cleaned. there were.
[0008]
Further, the pot seedling box described in JP 2000-316392A, Japanese Patent Publication No. 1-442647 and the like is forcibly sent to the seedling box washing section by the seedling box transporting nail, and both of the pot seedling boxes are viewed from the side. In what is washed while curving, even if the pot seedling box made of soft resin material etc. is curved, fatigue will occur that much, and depending on the years of use, symptoms such as the resin material will become brittle, In these inventions of the type that is washed while curving, there is a problem that the pot seedling box is damaged.
[0009]
Therefore, the present invention has been made in consideration of such problems, and when the pot seedling box is inserted into the pot seedling box cleaning apparatus, the operator does not adjust the timing of the apparatus, but what timing the apparatus side has. Therefore, it is an object of the present invention to be able to transport even if the pot seedling box is inserted, to be able to clean the pot seedling box so that there is no unwashed portion, and to eliminate damage to the pot seedling box.
[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the pot seedling box cleaning apparatus according to the present invention employs the following means.
[0011]
In other words, the present invention is characterized in that a synchronizer is provided for absorbing a front-rear shift when the seedling box transporting claw for transporting the pot seedling box and the pot hole are fitted.
[0012]
In this method, since the seedling box transporting claw has been conventionally forced to continuously rotate during the cleaning operation of the pot seedling box cleaning device, the worker must remove the pot seedling box in order to insert the seedling box transporting claw into the pot hole with good timing. As a result of providing a synchro device in the drive unit of the seedling box transporting claw, it was necessary to adjust the insertion timing, and as a result, absorption of the deviation before and after the seedling box transporting claw and the pot hole were fitted Even if the insertion timing is deviated, the seedling box transporting claw is momentarily cut into the driving force cut state and absorbs the deviation before and after that, so that the pot seedling box can be prevented from being damaged.
[0013]
Although the use of a commercially available one-way clutch is conceivable as the structure of the synchronizer of this means, the structure is complicated and easily damaged, and it works only in one direction, but it is inappropriate for this apparatus and is expensive. If the configuration of the present invention is adopted, there is an advantage that it is simple and has no failure, and can be effective not only in one direction but also in the front-rear direction, and is inexpensive.
[0014]
According to a second aspect of the present invention, the intervals between the plurality of seedling box guides that are in contact with the back side of the pot seedling box provided in the seedling box cleaning section are different on the inlet side and the outlet side of the seedling box cleaning section.
[0015]
In this means, conventionally, since a plurality of seedling box guides are provided so as to rub against the long side of the pot seedling box, the seedling box guide is covered with the pot seedling box and cannot be cleaned. However, in the embodiment of the present invention, two continuous round bars that are seamlessly connected from the entrance side to the exit side of the seedling box cleaning section are used as the seedling box guide. The interval is arranged in the center of the short side of the pot seedling box short side, the seedling box guide is bent near the center in the length direction, and the guide effect at the outlet is less than that at the inlet. Since the portion where the pot seedling box rubs against the seedling guide is different at the entrance and the exit, the sliding cleaning at least with the back surface cleaning brush is performed at the maximum in the entire seedling box cleaning path. Since it can be performed in half, there are no uncleaned parts. There is an advantage in that.
[0016]
Furthermore, in the past, the seedling box guide for guiding the pot seedling box was divided into a plurality of parts and provided at intervals or shifted, but this method inevitably cannot reliably guide the pot seedling box. Part of the pot seedling box that is made of a soft resin material or the like is prone to swell due to the influence of a cleaning brush or the like, and the pot seedling box is prone to damage or fatigue However, in the present invention, since it has a continuous guide structure with no joints from the inlet to the outlet, the pot seedling box is surely guided to the end and is being washed. There is an advantage that the deformation of the pot seedling box is minimized, and it becomes easier to assemble than the method in which the seedling box guide described above is divided into a plurality of parts, and the cost is reduced.
[0017]
In addition, although not claimed, in the conventional case where both are washed while curving the pot seedling box in side view, even if the pot seedling box made of a soft resin material is curved, the fatigue is increased accordingly. However, in the present invention, the pot seedling box can be washed on a straight line without curving, thus preventing damage to the pot seedling box. be able to.
[0018]

[0024]
In FIG. 1, A is a cleaning device, which has a seed box input port C and a seed box exit D in the front-rear direction of the box-shaped body 1, and a water reservoir 2 having a drain port 45 in its lumen. In addition, an inlet-side surface seedling attached in parallel to the airframe in a side view in a cleaning chamber provided with a surface cleaning sprinkling pipe 10 and a back surface cleaning sprinkling pipe 11 that discharges water from appropriate sprinkling holes 10a. There are a box guide 12, an exit-side surface seedling box guide 13, a backside seedling box guide 14, and a side surface seedling box guide 15, and is driven to rotate above the backside seedling box guide 14 in a form orthogonal to each seedling box guide. Long-side tips of a pair of rotating arms 5 that are equally distributed in the length left and right attached to the rotating shaft 7 below the cleaning brushes 3a and 3b for the back surface, the inlet-side surface seedling guide 12 and the outlet-side surface seedling guide 13 Surface cleaning that freely rotates in each part A brush 4 is attached, and the surface cleaning brush 4 revolves around the rotary shaft 7 so as to oppose the feeding direction of the pot seedling box B, and is opened to the pot seedling box surface side Ba. The tips of the brushes of the surface cleaning brush 4 are surely inserted into the recesses B ′ from the recesses B ′ opening of the pot seedling box B, so that the recesses B ′ can be effectively cleaned. Is called. Further, there is a water reservoir 2 in the cleaning chamber. When the surface cleaning brush 4 revolves, about half of the brush always passes through the water, and the brush itself is cleaned every rotation. Therefore, the pot seedling box B can always be washed with a clean brush.
[0025]
The back surface cleaning brushes 3a and 3b and the front surface cleaning brush 4 are formed slightly longer than the short side length of the pot seedling box B, and the rotation direction of the back surface cleaning brushes 3a and 3b is shown in FIG. As shown, the reverse surface cleaning brush 3b rotates in the same direction as the seedling box transport direction and rotates in a different rotation direction. The bristles are in contact with the entire outer wall of the convex portion on the back side Bb of the pot seedling box, and the pot seedling box back side Bb is effectively cleaned. In the embodiment, one cleaning brush 3a and 3b for the back surface and two brushes 4 for the front surface are attached. Of course, one or a plurality of brushes for the front surface may be attached.
[0026]
Further, an inlet-side seedling box transporting claw 9a and an outlet-side seedling box transporting claw 9b for transporting the pot seedling box B using the recess B ′ of the pot seedling box B are provided.
[0027]
The cleaning apparatus A further includes a motor M, a motor cover 43, a drain pipe 44, a drain pipe band 46, a moving wheel 48, and the like.
[0028]
FIG. 2 is a left side view of the above-described cleaning device A, and is a view in which about half of the pot seedling box B is inserted into the seedling box insertion port C. FIG.
[0029]
In this figure, a motor pulley 20 is attached to a motor M, and power is transmitted to the motor pulley 20 and the speed reduction pulley 21 by a power transmission V-belt 47. The speed reduction pulley 21, the back surface cleaning brush 3b, and the sprocket 22 are coaxially mounted, and power is transmitted to the sprocket 22, the sprocket 27, the sprocket 23, and the tension sprocket 24a by a power transmission chain 30a. A rotating arm 5 is fixed in the cleaning chamber on the same axis as the sprocket 27 and transmits the rotation to the surface cleaning brush 4.
[0030]
FIG. 3 is a right side view of the cleaning apparatus A, in which about half of the pot seedling box B is inserted into the seedling box insertion port C.
[0031]
Power from the motor M is transmitted to the sprocket 31 that is mounted coaxially with the sprocket 23, and power is transmitted to the tension sprocket 24b, the synchro gear 33, the sprocket 40, the tension sprocket 24c, and the sprocket 32 by the chain 30b. The sprocket 40 is coaxial with the back surface cleaning brush 3a and transmits rotational force.
[0032]
The rotating shaft 35 and the synchro plate 34 are fixed, and the seedling box cleaning section 16 has an inlet-side seedling box transporting claw 9a fixed to the rotating shaft 35 in the lateral direction of the machine body and substantially at the center. The synchro gear 33 is on the same line as the rotary shaft 35 and can freely rotate as will be described later.
[0033]
4, 5, 6, and 7 are explanatory diagrams of the operation of the synchro device. FIG. 4 is not shown, but the power switch is turned on to start the motor M, and the device is in an operating state. Thereafter, the pot seedling box B is inserted into the seedling box inlet C with the pot seedling box surface side Ba of the pot seedling box B facing downward, and the inlet side seedling box transporting claw 9a is inserted into the recess B ′ of the pot seedling box B, The pot seedling box B is transported to the seedling box cleaning unit 16 along each seedling box guide and is transported by about two thirds of the seedling box cleaning path 17.
[0034]
In the state as shown in FIG. 4, while the pot seedling box B is being transported only by the entrance-side seedling box transporting claw 9a, the synchro gear 33 and the synchro plate 34 are in the state shown in FIG. When driven to rotate, the stopper pin 33a hits the sync plate 34, the driving force is transmitted to the entrance-side seedling box transporting claw 9a fixed on the same axis as the rotation shaft 35, and the pot seedling box B is transported.
[0035]
When the pot seedling box B is being cleaned and proceeds to the seedling box outlet D while the pot seedling box B is being washed as it is, the recess B ′ at the front end of the long side of the pot seedling box B is fitted into the outlet side seedling box transporting claw 9b and the transport power is increased. The sprocket 32 that transmits the driving force to the exit-side seedling box transporting claw 9b and the synchro gear 33 that transmits the driving force to the inlet-side seedling box transporting claw 9a have different numbers of teeth. 9b is rotating slightly faster, but both the inlet side seedling box transport claw 9a and the outlet side seedling box transport claw 9b are fitted in the recess B 'of the pot seedling box B, so that the rotation speeds of the respective transport claws coincide with each other. To do. As shown in FIG. 6, the difference in rotation between the sprocket 32 and the synchro gear 33 at the time of the coincidence is that the synchro plate 34 that has hitherto hit the stopper pin 33a and transmits the driving force becomes slower than the rotation speed of the synchro gear 33, and the driving force is reduced. It is cut and moved to a position as shown in FIG.
[0036]
If it goes on as it is, the synchro plate 34 that has been hitting the stopper pin 33a and transmitting the driving force hits the opposite side of the stopper pin 33a, and this time the pot seedling box B is damaged due to the difference in the rotation speed of each conveying claw. Although it becomes a phenomenon, it is inserted into the recess B ′ at the front end of the long side of the pot seedling box B in the outlet seedling box transporting claw 9b so as to prepare for the insertion of the pot seedling box B to be washed next, After the transfer force is transferred to the outlet-side seedling box transfer claw 9b, when the synchro plate 34 is positioned as shown in FIG. 6 due to the speed difference between the transfer claws, the rear end on the long side of the pot seedling box B is The distance between the front and rear bodies of the transport claws is at a position away from the entrance-side seedling box transport claws 9a.
[0037]
After that, as shown in FIG. 7, the entrance-side seedling box transporting claw 9a in the no-load state has a structure in which a synchro gear 33 having a gap that does not hinder the chain driving ability is sandwiched in the synchro plate 34 in parallel. The synchro gear 33 can be rotated and rotates in synchronism with the synchro gear 33 as long as no load is applied to the inlet-side seedling box transporting claw 9a.
[0038]
When the pot seedling box B is inserted in the state as described above, even if the claw part of the inlet-side seedling box transport claw 9a and the recess B ′ of the pot seedling box B are not engaged with each other, the recess B ′ Since the driving force is not transmitted to the inlet-side seedling box transporting claw 9a in the front-rear direction at least half a pitch, the inlet-side seedling box transporting claw 9a of the inlet-side seedling box transporting claw 9a is not damaged in the pot seedling box B. A nail | claw part can be inserted and a synchro apparatus is always prepared for the insertion of the next pot seedling box B by this repetition.
[0039]
FIG. 8 explains claim 2. When the back surface side of the pot seedling box B, that is, the pot seedling box back surface side Bb is slidably cleaned, each back surface cleaning brush is located above the back surface seedling box guide, and therefore inevitably on the back seedling box guide 14 portion. The portion of the brush that hits and is hidden under the backside seedling box guide 14 cannot be slid and cleaned, but as shown in FIG. 8, the backside seedling box guide 14 constituting the backside seedling box guide 14 exits from the entrance side. The backside seedling box guide rods 14a and 14b, which are continuous to the side, were bent in consideration of not being insufficient to guide the pot seedling box B at the center in the longitudinal direction of the machine body. In this embodiment, the seedling box inlet is wide and the seedling box outlet is narrow, and at least the portion hidden by the back seedling box guide 14 is halved, not all, in the seedling box cleaning path 17. By doing so, it is possible to slidably clean the portion where at least one of the back surface cleaning brushes 3a and 3b is hidden under the back surface seedling box guide 14 appears.
[0040]
Of course, the back seedling box guide bars 14a and 14b may be attached obliquely without being bent.
[0041]
【The invention's effect】
As described above, the pot seed box cleaning device according to the present invention has hitherto required an operator to insert the pot seed box in order to accurately insert the seed box transporting claw into the pot hole without damaging the pot seed box. Although it had to be adjusted, the pot seedling box was damaged by the seedling box transporting claw no matter what timing the operator tried to insert the pot seedling box by providing a synchronization device to the pot seedling box cleaning device. There is an effect that it is not done.
[0042]
Furthermore, conventionally, the seedling box guide for guiding the pot seedling box is divided into a plurality of parts, and the ones provided at intervals or shifted are exited from the seedling box cleaning part inlet side provided in the pot seedling box cleaning part. The back seedling box guides , which are composed of continuous guide rods that are seamlessly connected to the side, are installed so that the interval between the seedling box cleaning unit inlet side and the outlet side is different, so that the unwashed part of the pot seedling box is completely In addition, the pot seedling box can be reliably guided from the entrance to the outlet of the cleaning section, so that the deformation of the pot seedling box during cleaning is minimized, easy to assemble, and low in cost. There is an effect.
[0043]
Furthermore, since the cleaning path of the pot seedling box cleaning device of the present invention is straight in side view, the pot seedling box can be prevented from being damaged as compared with the case where the pot seedling box has been curved and cleaned conventionally. There is.
