Description

  The present invention relates to an improvement of a transplanter provided with an empty box storage container for storing a pot seedling box.

  As a transplanter equipped with a conventional empty box storage container, the one described in Patent Document 1 is exemplified. As shown in FIG. 5, this transplanter inserts a flexible pot seedling box 1 connecting a number of pot-shaped seedling chambers 3 into an inclined seedling mounting table (not shown), and sends it downward one row at a time. On the way, an extrusion rod (not shown) is protruded from the bottom surface side of the pot seedling box 1 to take out the pot seedlings one by one. Further, the pot seedling box 1 after the pot seedling removal is arranged so that the bottom surface side of the pot seedling box 1 becomes a curved inner surface. Guided along the curved guide frame 58 guided in the same direction as the entrance of the seedling platform, the pot seedling box 1 coming out of the guide frame 58 is dropped into the empty box storage container 59. is there. The dropped pot seedling box 1 is stored in the empty box storage container 59 in substantially the same posture as when it comes out of the guide frame 58. The empty box storage container 59 includes a rear receiving portion 61 that is slightly inclined to support the upper surface of the pot seedling box 1, and a lower receiving portion 62 that protrudes forward from the lower end portion of the rear receiving portion 61. And a lateral receiving portion 63 that protrudes forward from the left and right sides of the side portion of the rear receiving portion 61.

  As shown in FIGS. 6A and 6B, the pot seed box 1 generally used in such a transplanter has a flexible opening (or crack) 2 into which the extruded bar can be fitted, as shown in FIGS. 6 (a) and 6 (b). The pot-shaped seedling chambers 3 are arranged in a grid pattern, and edge portions 5 having feed holes 4 for feeding the seedling boxes one pitch at a time are formed on the left and right sides thereof, and the whole has flexibility.

  However, as shown in FIG. 7, for example, in a state where the pot seedling box 1 is stored in the empty box storage container 59 up to the maximum number that can be stored, the bottom surface of the stored pot seedling box 1 is sent out from the guide frame 58. Sometimes the upper surface of the pot seedling box 1 slides. Since the pot seedling box 1 in the empty box storage container 59 is stored in almost the same posture as when it comes out from the guide frame 58, a plurality of adjacent pots connected to the bottom surface of the stored pot seedling box 1 are adjacent to each other. The bottom of the seed-like seedling room 3 and the openings of a plurality of adjacent pot-shaped seedling rooms 3 connected to the upper surface of the pot seedling box 1 delivered from the guide frame 58 are fitted, and are indicated by arrows in FIG. The pot seedling box 1 already stored in the container may be pushed upward to disturb the alignment of the pot seedling boxes 1 stored in the empty box storage container 59. The pot seedling box 1 in the pushed up state is an obstacle when the operator supplies the pot seedling box 1 to the seedling mounting base (not shown) from behind the empty box storage container 59. In addition, when the alignment of the pot seedling boxes 1 is disturbed, when the operator takes out the pot seedling boxes 1 stored in the empty box storage container 59 and stacks them on the empty box receptacle (not shown) installed on the machine body, It is necessary to rearrange the pot seedling boxes 1 and it takes extra time.

In order to solve the above problems, the transplanter of the present invention is:
Seedling box transfer means for transferring a flexible pot seedling box connected to a large number of pot-shaped seedling rooms;
Provided in the vicinity of the outlet of the pot seedling box in the seedling box transfer means, and an empty box storage container for storing a plurality of empty pot seedling boxes,
There is a case where either one of the bottom surface and the top surface of the pot seedling box already stored in the empty box storage container is sent out so that the other surface of the pot seedling box sent out by the seedling box transfer means slides. A transplanter,
The empty box storage container stores the pot seedling box in a state of being relatively inclined with respect to the pot seedling box sent out by the seedling box transfer means in a plane substantially parallel to the one surface of the pot seedling box. Is configured to do.

  According to this configuration, the pot seedling box is in the state of being relatively inclined with respect to the pot seedling box sent out by the seedling box transfer means in a plane substantially parallel to the one surface of the pot seedling box. Since it is stored in the box storage container, either one of the bottom surface and the top surface of the pot seedling box already stored in the empty box storage container is the other surface of the pot seedling box sent out by the seedling box transfer means. A plurality of pot-shaped seedling rooms adjacent to each other connected to one surface of the pot seedling box already stored in the empty box storage container, and the seedling box transfer means The relative positional relationship with the plurality of adjacent pot-shaped seedling chambers connected to the other surface of the pot seedling box sent out by the above is shifted as a whole, and they do not fit each other. For this reason, unlike the conventional example, it is possible to prevent the alignment of the pot seedling boxes stored in the empty box storage container.

  According to the transplanter provided with the empty box storage container according to the present invention, there is an excellent effect that the alignment of the pot seedling boxes stored in the empty box storage container can be prevented.

  1 to 4 show an embodiment of a transplanter embodying the present invention. This transplanter is provided in the middle of the transfer path of the seedling box transfer means 11 for transferring the flexible pot seedling box 1 connected to a large number of pot-shaped seedling rooms 3, and the seedling box transfer means 11; A seedling extraction means 12 that protrudes the extrusion bar 12a from the bottom surface side of the pot seedling box 1 to take out the pot seedlings in a row, and is provided detachably near the outlet of the pot seedling box 1 in the seedling box transfer means 11, An empty box storage container 13 for storing a plurality of pot seedling boxes 1 is provided. The pot seedling taken out from the pot seedling box 1 is planted in the field by the planting unit 14. Also, the pot seedling box 1 stored in the empty box storage container 13 is taken out by an operator and stacked on an empty box receiver (not shown) installed on the machine body. In each figure, the arrow F indicates the front side of the aircraft. The pot seedling box 1 is the same as that described in [Background Art].

  The seedling box transfer means 11 inserts the pot seedling box 1 into the inclined seedling mount 16 and feeds it downward one row at a time. After passing through the seedling extraction means 12 on the way, the pot seedling box 1 is transferred to the bottom surface of the pot seedling box 1. The guide is guided in the same direction as the entrance of the seedling table 16 (upward when viewed from the front of the transplanter) along the curved guide frame 17 that guides the curved inner surface. Near the outlet of the guide frame 17, a spring member 18 that is always in contact with the bottom side of the pot seedling box 1 and biases the pot seedling box 1 toward the empty box storage container 13 is installed. The substantially standing pot seedling box 1 coming out of the frame 17 is dropped into the empty box storage container 13.

  The empty box storage container 13 includes a rear receiving portion 21 that is slightly inclined rearward to support the upper surface of the pot seedling box 1 and a lower receiving portion that protrudes forward from the left and right sides of the lower end portion of the rear receiving portion 21. And a horizontal receiving portion 23 projecting forward from the left and right sides of the side portion of the rear receiving portion 21 so that the empty pot seedling box 1 can be stored in a substantially upright state.

  At the front ends of the left and right lateral receiving portions 23 in the empty box storage container 13, there are provided upper locking portions 25 that project toward the inside of the machine body, and are provided on the left and right side surfaces of the seedling platform, respectively. The upper locking hole 26 is engaged from the outside of the machine body. In addition, on the left and right sides of the lower end side of the rear receiving portion 21, there are provided lower locking portions 27 that project substantially downward, and the lower locking portions 27 are provided on the body of the transplanter. The lower support piece 28 that is supported is engaged with the lower locking hole (not shown) from above. In order to remove the empty container 13, the operator removes the left and right upper locking portions 25 from the upper locking holes 26, and then the lower locking portion 27 is removed from the lower locking holes. It is only necessary to lift the entire empty box storage container 13 upward. In order to attach the empty box storage container 13, the reverse procedure is performed. Thus, the empty box storage container 13 of this example can be easily attached and detached without using a tool, and the planting portion provided substantially below the empty box storage container 13 Maintenance work such as 14 can be easily performed.

  The left and right support parts 22 are provided at different heights (in the present example, the position on the right side is low). As shown in FIG. 4, the pot seedling box 1 is on the side of the machine body as viewed from the front side of the transplanter. It is configured to be stored in a tilted state (in this example, tilted about 4 ° to the right side of the aircraft). Thus, as shown in FIG. 2, the empty box storage container 13 has a pot seedling box for the pot seedling box 1 (indicated by a two-dot chain line in the figure) sent out by the seedling box transfer means 11. The pot seedling box 1 (shown by a solid line in the figure) is stored in a state of being relatively inclined in a plane substantially parallel to the bottom surface in FIG.

  Further, as shown in FIG. 1, the left and right lower receiving portions 22 are provided so as to project at right angles to the rear receiving portion 21 in a side view, and the rear receiving portion 21 is inclined to the rear of the fuselage. It is in a state of being inclined so as to become lower toward the rear receiving portion 21 side. For this reason, the pot seedling box 1 sent out from the guide frame 17 and falling is brought closer to the rear receiving portion 21 side. In addition, since the lower receiving portion 22 protrudes at a right angle to the rear receiving portion 21 as described above, when the two pot seedling boxes 1 are stored, as shown in FIGS. The positions of the pot-shaped seedling chambers 3 connected to the seedling box 1 coincide with each other, and the pot-shaped seedling chambers 3 of both pot seedling boxes 1 are fitted. For this reason, it is easy to take out the two pot seedling boxes 1 and the pot seedling boxes 1 are fitted and joined together, so that the operator takes them out and installs them in the empty box receptacle ( It is difficult to be blown away by the wind when stacked in a not-shown manner.

  As shown in FIG. 5, in the conventional empty box storage container 59, the lower receiving portion 62 protrudes at an acute angle with respect to the rear receiving portion 61 in a side view. This is because the conventional empty box storage container 59 can store a large number of pot seedling boxes 1, so that the pot seedlings sequentially coming out from the guide frame 58 can be obtained by configuring the lower receiving part 62 in this way. This is because a predetermined number of pot seedling boxes 1 cannot be stored in the empty box storage container 59 unless the box 1 is surely moved to the rear receiving portion 61 side. Since the lower receiving part 62 is configured as described above, the pot seedling boxes 1 stored adjacent to each other in the conventional empty box storage container 59 are pot-shaped connected to the pot seedling boxes 1. The positions of the seedling chambers 3 do not coincide with each other, and the pot-shaped seedling chambers 3 of both pot seedling boxes 1 are not fitted with each other. If a plurality of pot seedling boxes 1 are not connected to each other, they can be easily blown by the wind when stacked on the empty box receptacle, so that the pot seedling chambers 3 of the pot seedling box 1 are fitted together. There is a problem that it is necessary to re-apply, and it takes extra time.

  By the way, the transplanter of this example is small, and the empty box storage container 13 is provided immediately behind the seedling box transfer means 11, and the capacity of the empty box storage container 13 is also reduced. For this reason, as shown in FIG. 1, when one pot seedling box 1 is already stored in the empty box storage container 13, the seedling box transfer means 11 moves the bottom surface of the stored pot seedling box 1. It is sent out so that the upper surface of the pot seedling box 1 to be sent out slides.

  According to the transplanter of this example configured as described above, relative to the pot seedling box 1 sent out by the seedling box transfer means 11 in a plane substantially parallel to the bottom surface of the pot seedling box 1. Since the pot seedling box 1 is stored in the empty box storage container 13 in an inclined state, the bottom of the pot seedling box 1 stored in the empty box storage container 13 is sent out by the seedling box transfer means 11. As shown in FIG. 2, a plurality of adjacent pots connected to the bottom surface of the pot seedling box 1 stored in the empty box storage container 13 may be used. The relative positional relationship between the seedling chamber 3 and a plurality of adjacent pot-shaped seedling chambers 3 connected to the upper surface of the pot seedling box 1 sent out by the seedling box transfer means 11 is entirely shifted so that they are fitted to each other. There is nothing. For this reason, unlike the conventional example, the alignment of the pot seedling boxes 1 stored in the empty box storage container 13 can be prevented from being disturbed.

In addition, this invention is not limited to the said embodiment, For example, it can also be suitably changed and embodied as follows, for example in the range which does not deviate from the meaning of invention.
(1) The empty box storage container 13 is configured so that three or more pot seedling boxes 1 can be stored.
(2) Configure the transplanter so that the front and back of the pot seedling box 1 stored in the empty box storage container 13 is opposite to that of this example.

It is a principal part side view (partial cross section) of the transplanter provided with the empty box storage container which concerns on this invention. It is the II-II sectional view taken on the line of FIG. It is a principal part side view (partial cross section) of the transplanter. It is the IV-IV sectional view taken on the line of FIG. It is a principal part side view of the conventional transplanter. It is the (a) side view and (b) partial top view of a pot seedling box. It is a principal part side view of the conventional transplanter.
