Description

  The present invention relates to a continuous potted seedling transplanter equipped with irrigation means.

  Conventionally, on a machine base having a lower surface on the rear side in the traveling direction as a ground contact surface, a potted seedling placing unit for placing continuous potted seedlings sequentially from the front side in the traveling direction, and a continuous drawn from the potted seedling placing unit A groove that includes a potted seedling guide portion that guides the potted seedlings arranged in a row, and a potted seedling feeding portion that feeds continuous potted seedlings from the potted seedling guide portion onto the planting surface, and further forms a planting groove in the field 2. Description of the Related Art A continuous potted seedling transplanting machine is known in which a cut portion is provided on a grounding surface of a machine base and a handle is provided at a front end portion in the moving direction of the machine base (for example, see Patent Document 1). In the above-mentioned continuous potted seedling transplanting machine, when the operator checks the handle, the groove cutting part forms a single planting groove on the planting surface of the field, and the continuous pot pulled out from the potted seedling placement part into the planting groove. Since the seedlings are aligned in a line by the potted seedling guide unit and fed out from the potted seedling feeding unit, it is not necessary to provide a mechanism for taking out crops (seedlings) one by one. Moreover, since the planting interval of the individual potted seedlings is determined by the length of the connecting piece connecting the individual potted seedlings, a mechanism for adjusting the planting interval can be omitted.

In the above-mentioned continuous potted seedling transplanting machine, the overall mechanism can be configured extremely simply, so that it is possible to significantly reduce the weight compared to the previous transplanting machines, and as a result, a prime mover such as a tractor is used. Therefore, the transplanter can be moved by the operator pulling. Therefore, the above-mentioned continuous potted seedling transplanting machine can be easily introduced to relatively small-scale farmers because the capital investment is low, and in addition, it is extremely easy to operate, even for women and girls. Can be handled easily.
By the way, when transplanting is performed in the high-temperature season in midsummer, the transplanted crop may be poorly grown and die due to drying. Therefore, irrigation may be performed immediately after the transplanting is completed. And since the work in the high temperature period is a heavy burden for the operator, I want to finish it in as short a time as possible. Therefore, there has been a demand for a continuous potted seedling transplanter capable of performing irrigation in parallel with transplantation.

  For example, as a transplanter in which irrigation is performed in parallel with transplantation, the one disclosed in Patent Document 2 is known. This transplanter is an electric pump that pumps water stored in a water tank, An irrigation means including a sensor for detecting that the planting tube has entered the ridge and an electromagnetic on-off valve that operates based on a detection signal of the sensor is required. As a result, the transplanter becomes heavier and difficult to pull by the operator, so it is difficult to adopt the irrigation means to the continuous potted seedling transplanter. In addition, capital investment increases, making it difficult to introduce to small-scale farmers.

  The irrigation means includes a tank 21 that stores water for irrigation, a support frame 22 that is provided on the frame 11 of the machine base 3 and supports the tank 21, and water that has flowed out from an opening 21 a provided at the bottom of the tank 21. The water receiving part 23 to receive and the hose 24 which sends the water received by this water receiving part 23 toward the potted seedling feeding part 8 are included. As the tank 21, a commercially available square PET bottle having a capacity of 2 L can be used. Hereinafter, the tank 21 refers to the square-shaped plastic bottle, and the opening 21a refers to the spout of the plastic bottle. The support frame 22 includes a pair of posts 22 provided at predetermined intervals on both sides of the pair of guide plates 13 in the width direction of the machine base 3 (vertical direction in FIG. 1), and a substantially bottomed cylinder is provided between the pair of posts. The water receiving portion 23 formed in a shape is fixed at a predetermined height from the frame 11. Further, an irrigation tap 35 having a diameter substantially the same as the inner diameter of the hose 24 is provided on the outside of the bottom of the water receiving portion 23.

  As shown in FIG. 4, a tank holding portion 26 that holds the tank 21 is provided on the upper part of the pair of posts 22. The tank holding portion 26 includes a holding metal fitting 26 a that holds the body portion of the tank 21 and a holding metal fitting 26 b that holds the shoulder portion of the tank 21 (the inclined portion of the square-shaped plastic bottle). The holding metal fitting 26a is formed in a substantially U shape, and both circumferential ends are bent inward. Further, the holding metal fitting 26a has an inner dimension (interval between a pair of opposed plates) in the width direction of the machine base 3 (vertical direction in FIG. 1) slightly smaller than an outer dimension of the held portion of the opposing tank 21. Is set. As a result, the tank 21 is fixed by being sandwiched between a pair of plates whose shoulders are supported by the holding metal fittings 26b and whose body parts are opposed to the holding metal fittings 26a. The holding metal fitting 26b is constituted by a pair of plates provided along both shoulders of the tank 21. And the tank 21 is hold | maintained by the holding | maintenance part 26, and as FIG. 5 shows, the state in which the opening 21a floats from the bottom face 23a of the water receiving part 23, in other words, the opening 21a is the water receiving part 23's. The height is set higher than the bottom surface 23 a and lower than the height of the side wall of the water receiving portion 23.

  Further, the irrigation means has a water supply port 28 provided at the center of the bottom of the water receiving portion 23 and having a water supply port 27 opened to the bottom surface 23a. One end (upstream end) of a hose 24 made of a material having a certain degree of flexibility is connected to the water supply port 28. The hose 24 is supported by a hose bracket 29 attached to one post 25 (left post 25 in FIG. 4) of the support frame 22, and the other end (downstream end) is above the potted seedling feeding portion 8. To be guided to. Further, as shown in FIG. 6, the irrigation means includes an irrigation amount adjusting member 30 (irrigation amount adjusting means) inserted into the water supply port 28 from the water supply port 27 of the water receiving unit 23 as necessary. The irrigation amount adjusting member 30 is formed by bending a wire into an L shape, and several types of diameters are prepared as necessary. The irrigation means inserts the selected irrigation amount adjusting member 30 into the water supply port 28 from the water supply port 27 and adjusts the opening area of the water supply port 27, thereby allowing the water receiving unit 23 to pass through the water supply port 28. Thus, the amount of water supplied to the hose 24 (water supply amount) is adjusted.

  Reference numeral 31 shown in FIGS. 1 and 2 is an auxiliary handle attached to the frame 6. Reference numeral 32 denotes a chisel that prevents the rear portion of the machine base 3 from being lifted with respect to the field 2, and the chisel 32 has a mechanism (not shown) that adjusts the biting angle with respect to the field 2. Further, reference numeral 34 denotes a connecting plate that is bent in a substantially square shape in a side view shown in FIG. 2 and is laid between the potted seedling placement portion 5 and the potted seedling guide portion 7. The bent portion 34a can prevent the continuous pot body drawn out from the pot body mounting section 5 from being pulled out and pulled out together (without the connecting piece extending).

  Next, the operation of this embodiment will be described. First, prior to transplantation, a pot seedling stand containing continuous potted seedlings is set on the potted seedling placement unit 5 of the continuous potted seedling transplanting machine 1. In addition, a commercially available thing is used for a potted seedling stand, and what is described in WO2006 / 07070738 etc. can be used for a continuous potted seedling, for example, It is not limited to these. Furthermore, an arbitrary position of the hose 24 of the irrigation means is closed with a clip or the like, and in this state, as shown in FIG. 4, a tank 21 containing water (a square PET bottle with a capacity of 2 L) is placed in the irrigation means. The opening 21a (the above-mentioned PET bottle pouring spout) is attached to the tank holding portion 26 in a downward direction. As a result, the water in the tank 21 flows out from the opening 21a. However, as shown in FIG. 5, the water level in the water receiving portion 23 becomes higher than the opening 21a in the tank 21. The water outflow from the opening 21a stops.

  After completion of the transplant preparation, the continuous potted seedling transplanter 1 is positioned at the planting start position of the field 2. And the front-end | tip of a continuous potted seedling is pulled out from the potted seedling stand on the potted seedling placement part 5 of the said continuous potted seedling transplanting machine 1, and the pulled-out continuous potted seedling is made into a potted seedling guide part 7 and a potted seedling feeding part 8. Pass through, and plant and fix the tip in a planting groove formed in the field 2 in advance. Next, after removing the clip that has blocked the hose 24 of the irrigation means, the handle 16 is pulled to move the continuous potted seedling transplanter 1 forward, that is, to the right in FIG. 1, FIG. 2, and FIG. As the continuous potted seedling transplanting machine 1 advances, the chisel 31 located at the front end of the groove cutting part 4 bites into the field 2 and suppresses the lifting of the rear part of the machine base 3, so that a planting groove is formed in the field 2 by the groove cutting part 4. It is formed. At the same time, the continuous potted seedlings are sequentially drawn from the potted seedling stand on the potted seedling placement unit 5, pass between the pair of guide plates 13 of the potted seedling guide unit 7 and the potted seedling feeding unit 8, and are notched. It is drawn from 12 toward the planting groove.

  Furthermore, in the continuous potted seedling transplanting machine 1 of the present embodiment, the continuous potted seedlings fed into the planting grooves are irrigated by the irrigation means in parallel with the above-described series of transplanting flows. Specifically, the water in the water receiving part 23 supplied from the tank 21 is supplied through the water supply port 28 and the hose 24, and is fed into the planting groove from the other end (downstream end part) of the hose 24. Water is irrigated by the continuous potted seedlings. When the water level in the water receiving unit 23 is lowered to some extent with respect to the position of the opening 21a of the tank 21 due to irrigation, the water in the tank 21 is supplied from the opening 21a to the water receiving unit 23, and the water receiving unit 23 When the water level inside becomes higher than the opening 21a of the tank 21 again, the supply of water from the opening 21a in the tank 21 is stopped, and the supply of water from the tank 21 to the water receiving unit 23 is repeated through transplantation.

This embodiment has the following effects.
According to this embodiment, since the irrigation means is provided in the continuous potted seedling transplanter 1, it is possible to irrigate the continuous potted seedlings planted in the field 2 in parallel with the transplanting of the continuous potted seedlings. Thereby, in the conventional continuous potted seedling transplanter (for example, refer to Patent Document 1), when irrigation is necessary in the high temperature season of midsummer, the operation time is long because the field 2 was irrigated after the transplanting operation was completed. Although the burden on the worker was large, the transplanting operation including irrigation can be rationalized by performing irrigation in parallel with the transplantation, and as a result, the burden on the worker can be reduced.
The irrigation means includes a tank 21, a support frame 22 that supports the tank 21, and a hose 24 that supplies water stored in the tank 21 toward the potted seedling feeding portion 8, so that an electric pump, a sensor, Compared to conventional irrigation means including an electromagnetic on-off valve or the like (see, for example, Patent Document 2), it can be configured to be extremely lightweight. Thereby, since the increase in the weight of the continuous potted seedling transplanter 1 by adopting the irrigation means is suppressed to the minimum, the continuous potted seedling can be pulled by the operator without using a prime mover such as a tractor. The transplanter 1 can be moved. Furthermore, since the irrigation means has a very simple structure and is easy to operate, it is possible to safely and easily perform transplantation work including irrigation even for women, women, elderly people, and the like. And since capital investment is minimal, it can be easily introduced to small-scale farmers.
Moreover, since a used plastic bottle can be used as the tank 21, it can reduce manufacturing cost and can contribute to environmental conservation.
In addition, the receptacle 21 is disposed between the tank 21 and the water hose 24 so that the opening 21a of the tank 21 held by the tank holding portion 26 does not contact the bottom surface 23a (floats from the bottom surface 23a). Since the water portion 23 is provided, a mechanism for connecting the opening 21a of the tank 21 and the hose 24 is not required, and the selection (shape) of the tank 21 can be given flexibility.
Further, if necessary, irrigation amount adjusting members 30 (irrigation amount adjusting means) of several kinds of diameters are prepared, and the selected irrigation amount adjusting member 30 is inserted into the water supply port 28 from the water supply port 27. By adjusting the opening area of the water supply port 27, the amount of water supplied to the hose 24 from the water receiving part 23 via the water supply port 28 (water supply amount) is adjusted, so the irrigation amount (unit time in the hose 24) The structure for adjusting the (water supply amount per hit) can be configured very simply without using a valve or the like.
The irrigation amount adjusting member 30 may be of any shape and material that can adjust the opening area of the water supply port 27. The wire is not limited to the wire in this embodiment, and may be a thin plastic rod.

In addition, embodiment is not limited above, For example, you may comprise as follows.
In this embodiment, the water receiving part 23 is provided between the tank 21 and the hose 24 to configure the irrigation means. However, the hose 24 may be directly connected to the tank 21 to configure the irrigation means. In this case, a member corresponding to the water supply port 28 of the water receiving portion 23 is attached to the cap of the plastic bottle as the tank 21, and one end (upstream end portion) of the hose 24 may be connected to this member.
In the present embodiment, a square PET bottle having a capacity of 2L is used as the tank 21. For example, a round PET bottle or a PET bottle having a different capacity may be used. In this case, this can be dealt with by attaching an attachment or the like to the tank holder 26. Furthermore, a dedicated tank 21 as shown in FIG. 7 can be used. A water injection lid 33 that can be opened and closed is provided on the upper surface of the tank 21. A tank holding portion 26 having a shape corresponding to the tank 21 is attached to the upper portion of the pair of posts 25. In this case, whether or not the water receiving portion 23 is provided between the tank 21 and the hose 24 can be appropriately selected.
Further, when the tank 21 containing water is attached to the tank holding portion 26 of the irrigation means, instead of closing the tip of the hose 24 with a clip or the like, as shown in FIG. The hose 24 may be closed by plugging it into.
