The present invention relates to an apparatus for filling seedling soil with hardness uniformly averaged to a seedling container, such as a seedling transplanting paper container house pot formed by connecting a plurality of flower pots made of paper or paper such as paper. will be.

Filling seedling soil into seedlings for seedling transplanting, seedlings such as rice, vegetables, tobacco, beets, and sowing seedlings for a certain period of time, and then transplanting them using a transplanter can save effort in transplanting seedlings. It is used a lot.

The method of filling the paper container aggregates into the paper container aggregates is generally described in Japanese Utility Model Publication No. 48-3300 for rice paddies, vegetables, and the like. The paper container assembly is spread out on a board where the projections are installed to correspond to each paper container, and the mother soil is filled with human hands, and the upper surface is pressed by the inverting plate to invert, ) Is removed and formed. Seeds were sown in the seeding holes, or paper canisters were placed directly on the seedling boxes, and both ends were fixed by the side walls and the comb teeth of the seedling boxes, and the mother soil was filled with human hands, and then pressed by rollers or brushes.

In addition, while feeding the seedling soil hopper installed in the upper part of the tray or roller conveyor using the paddy rice seedling box seedling soil supply device, the upper surface of the upper surface is fed by the seedling soil hopper installed above. Although some of them are suppressed, the filling firmness (density) of the bed soil in each pot is insufficient, resulting in collapse and fall of the bed soil in handling when transplanted.

Therefore, as disclosed in Japanese Patent Application Laid-open No. 58-31891, a method of increasing the filling firmness by giving a small vibration from the lower surface of the paper container assembly to which the mother soil is supplied by feeding on the transfer conveyor is also proposed.

In transplanting seedlings using aggregates of paper barrels, the seedling soils filled in the pots must maintain the firmness of the seedlings planted in the soil when transplanted.

Therefore, it is necessary to harden the filling firmness of the bed soil in each pot at the time of supply filling of bed soil in a large quantity of paper container aggregates.

In case of spreading paper bucket collection pot on projection board or using paper comb in seedling box, supplying bedding soil from the upper surface and using a roller or brush to put down by human hand. It is not possible to obtain the target hardness only by meeting suppression, and only the minimum hardness can be maintained by the suppression by several compactions from the upper surface by the brush.

When rice plants and vegetables are grown in pots made from pots of paper pots that do not have a firmness, the paper pots assembled on transplanters during rice transplanting are almost indigenous on the inclined stand. It becomes crushed, and the implant holder pitch does not match, making the implant operation impossible.

In addition, in the case of small vegetables, not only the workability deteriorates remarkably due to the collapse of the indigenous part in the pot during transplantation, but also the poor growth after transplantation, and the transplantation in the same way as in the case of paddy rice transplanting. Disables retention in holders. In addition, as shown in Japanese Patent Publication No. 58-31891, when the base plate soil supplied from the upper surface is suppressed by giving a small vibration to the striking body from below the paper container assembly pot on the conveying belt, considerable firmness can be obtained. The bed soil supplied by the belt feeder from the bed soil hopper shows a mountain shape in the belt advancing direction from the upper side of the paper container assembly, so each pot is suppressed by simply shaking it. It is not possible to make uniform filling.

MEANS TO SOLVE THE PROBLEM As a result of repeating earnest research about the apparatus which can correct the defect mentioned above and fill the paper container assembly powder with the base soil with uniformity and sufficient firmness, the development board which advances on a conveying conveyer ( Hereafter, it is simply referred to as a board), or from the upper part of the paper container aggregates developed in the nursery box (hereinafter simply referred to as a box), the mother soil is continuously supplied by a belt feeder or the like, and then the paper container aggregates The piled up soil piled up in the shape of a mountain on the top surface is scattered by sticking the sticks sticking out from the width of the paper container, and then evenly arranged at a constant height. Densification is carried out, and the pressure reduction and pressure are sequentially reduced to the height of the paper container assembly by a two-stage voltage roller arranged in series. By charging device could be a nursery soil in nursery soil can be extremely hard to get charged paper through collection pots.

In addition, the two-stage voltage roller may be a plurality of rollers, and in the case of the last-row roller, the centers of the voltage rollers are shifted from the center of the rollers on the conveying belt side in the conveying direction, so that paper container aggregates are placed at both ends of the box. We can prevent obstacles such as overload to voltage roller by comb to fix.

In the present invention, the mother-plate soil continuously supplied to the paper-collecting aggregate is formed in the form of a mountain, and the substrate is formed by striking the line-shaped body provided to cross the paper-cold aggregate-transfer path so as to disperse it. Since vibration is applied to the soil, the mother soil is shrunk and press-in suppressed by pressurization to the height of the sum of paper bins by two-stage voltage rollers arranged in series.

In addition, since the last row of the voltage rollers shifts the center of the rollers back and forth to make the height of the paper container collection pot between each outer circumference, the height of the box side wall is increased by the comb fixing the paper container assembly to the box side wall. When the height is higher than the sum of pots, the center is shifted downward so that the center can be shifted down easily.

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

In FIG. 1, FIG. 2, and FIG. 3, (1) is a pair of machine frame arrange | positioned in parallel, Between the machine frames 1 parallel in this way, the rotating shaft 2 is hypothesized, Roller (3a) on rotating shaft (2) e) and the rollers 3a between the machine frames 1 The conveyance path | route of the paper container aggregation part 4 is formed by the belt suspended in e).

As shown in Fig. 4 (a), the paper container assembly pot 4 is fixed by hooking the front and rear end side walls of the seedling box 5 and the front and rear ends of the paper container assembly pot 4 after development with a comb teeth 6 or not. Otherwise, as shown in FIG. 4 (b), the front and rear ends of the development paper container assembly 4 are fixed to the comb 6 set up at the front and rear ends of the deployment plate 7 and placed on the conveying path.

(8) is a hopper provided above the conveyance path of the paper container aggregation part 4, and is fixed to the attachment frame etc. which were provided in the machine frame 1, and the like. The bottom part of the hopper 8 is provided with the belt feeder 9, and the bed soil of the hopper 8 is located in the position which corresponded upward to the tip part near the conveyance direction of the potted plant of the belt feeder 9, and the rotation direction of the reverse direction. The gate 10 which can be adjusted up and down to become a supply port is provided.

The belt feeder (9) has a primary voltage roller (11) inside the belt to press the upper surface of the bed soil of the paper container assembly (4) from which the outer surface of the portion rotated from the bottom feeds the bed soil. And the secondary voltage roller 12. The outer surface of the lower rotary motion part of the belt feeder 9 is inclined so as to contact the upper surface of the paper container assembly 4 from the lower part of the secondary voltage roller 12. Moreover, this pressurization is performed by the pressurization in both the rollers 3a corresponding to the primary voltage roller 11, respectively, on a common vertical line. On the other hand, the axes of the secondary voltage roller 12 and the roller 3b are shifted back and forth, as shown in FIG. 2, so that the height of the side wall of the box 5 is the main surface of the maximum diameter of the voltage roller 12 and the roller 3b. The gap is widening so as not to get caught in between.

In this embodiment, the primary voltage roller 11, the secondary voltage roller 12, and the two-stage voltage roller have been described. However, the number of stages of the voltage roller may be further increased as necessary.

The rotational speed (circumference: 周 速) of the belt feeder is the same speed as the conveying path because the outer circumferential surface of the lower rotary motion part of the belt feeder 9 is approached and comes into close contact with the upper surface of the paper feeder. An action of leaving a part of the top bed soil behind is generated, and when it accumulates, it damages the rear part of the paper container assembly 4, which is faster than the speed of the conveying path.

(13) is to disperse the bed soil in a state that contains a lot of mountain-like soil supplied on the paper container assembly pot (4) of the box (5) installed to cross the downstream and downstream of the bed soil feed section of the belt feeder (9) to a constant height The rod 13 is provided at a suitable distance from the upper surface of the paper container assembly pot 4 over the conveying path, and the rod 13 can disperse the mountain part as if it thins the bed soil on the paper container assembly pot 4. As it should be good, it is 3 8 Round or square ones can be used, usually 3 5 Use

(14) is located below the base plate soil supply part at the tip of the belt type feeder (9), and beats the box (5) of the lower surface of the conveyance path or the bottom of the board (7), and vibrates in the paper container assembly (4). As a striking device for applying a force, a cam hole 17 having a hammer 18 fixed to the top thereof is engaged with the cam 16 fixed to the rotating shaft 15 provided on the machine frame 1. . Cam ball 17 is fixed to the rear end one end of the spring 19, the other end of the spring (19) is always pulled to pull the cam ball 17 upwards and fixed to the machine frame (1) have.

Therefore, when the cam ball 17 engaged with the cam 16 is disengaged in accordance with the rotation of the cam 16, the cam ball 17 is pulled upwards and the tip hammer 18 feeds the bed soil on the conveying path. The bottom of the box 5 holding the (4) is beaten. At this time, when the cam ball is lifted upwards to an unlimited number, the stopper 20 restricts the pulling force of the spring 19 to the machine frame 1 so as not to rise above a certain height. It is installed to regulate the height of the cam ball to rise above the 17.

The cam ball 17 can be made of metal, synthetic resin, or the like. However, it is effective to coat the cushion rubber around the cam ball 17 and the hammer 18 so as to soften the impact during a collision. .

21 is a pressurizing roller which is located above the hitting device 14 and presses both left and right sides of the seedling box 5 which holds and expands the paper container assembly 4 from the upper side, Injury of the box 5 when the bottom of the box 5 is beaten is prevented.

Numeral 22 denotes auger, 23 denotes a voltage roller, 24 denotes a brush, and a primary voltage roller 11 and a secondary voltage roller 12 form a paper container assembly. 4) When the base plate soil on the top side is pressed down, the base plate soil of a little thickness on the top side of the paper container acts to disperse the edges on each paper box of the paper container assembly (4) downward. Since the bed soil which overflows the edge of the paper container remains as it is on the paper container assembly 4 after passing through the secondary voltage roller 12, this is scraped out by the auger 22 to both sides and then the top surface is removed. While the base plate filling to the paper container assembly pot 4 is finished by suppressing the voltage roller 23 and making it even with the brush 24, scraping the paper container assembly pot 4 with the auger 22 is completed. When it is developed and fixed on the top, and the mother soil is supplied to the belt feeder (9), The supply width of the air supply 9 is approximately equal to or slightly wider than the width of the paper container assembly 4, and the belt type feeder can obtain a relatively stable supply amount at the center portion, and both ends thereof have a smaller supply amount than the center portion. There are many cases. Therefore, together with the mother soil which overflows from the primary voltage to the left and right sides through the secondary voltage sequentially, the left and right sides generate a portion where the filling firmness of the mother soil is insufficient compared with the central portion.

For this reason, the auger 22 is left to leave the remaining soil scraped from the center portion on both sides so as to leave the bed soil which is scraped to the left and right sides so as not to be filled with the width of the paper container assembly pot 4. By pressing the remaining soil on both sides with the voltage roller 23, it is possible to eliminate the paper container pot portion lacking the filling firmness.

Subsequently, such driving is performed via the chain 26 from the electric motor 25 installed in the machine frame 1, and the rollers 3a, 3b, 3c, and 3d constituting the conveying path. Sprockets 27a, 27b, 27c, 27d, and 27e are fixedly installed on the shafts 2 and 3e, respectively, and the sprockets 25a and chains of the electric motor 25 are fixed. Interlocked movement by (24).

28 is a sprocket installed on the shaft 2 of the roller 3e, and is interlocked with the chain 30 and the small sprocket 29 provided on the rotary shaft 15 of the cam 16 of the striking device 14. There is a hit number of 5 for 1 second. In order to make it about six times, the rotation speed of the cam 16 is made small by the speed change by the sprocket 28 and the sprocket 29. As shown in FIG.

The hammer 18 of the striking device 14 is configured to install two hammers 18 on both sides of the machine frame 1 so as to tap the bottom left and right sides of the box 5, and alternately beat them. One side beats about three times per second. The number of beats is determined appropriately according to the size, depth, etc. of the paper container assembly pot (4), but usually 5 for 1 second. About six times.

The belt feeder 9 has a sprocket 27c installed on the shaft 2 of the roller 3c, and an intermediate gear 31 which engages with the gears of the primary voltage roller 11 and the secondary voltage roller 12. It is interlocked by the chain 33 provided between the sprockets 32 installed in the shaft of the shaft, and the secondary voltage roller 12 also serves as the driving side pulley of the belt type feeder 9, so the belt type feeder (9) is a front end position of the secondary voltage roller 12 and the mother soil feed section, the flow of the shaft supported on the shaft provided between the machine frame (1) formed in the side wall shape under the hopper (8) It is installed between the wool 34 to constitute a belt feeder (9) to rotate the belt. Moreover, the auger 22 and the brush 24 are installed between the sprockets 35, 36 and 37 provided in each shaft, and the large sprocket 38 provided in the shaft of the intermediate gear 31. As shown in FIG. The chain 39 is in interlocking rotational motion.

The present invention is constituted as described above. The rollers 3a, 3b, 3c, 3d, and 3e of the conveying path are rotated by the drive of the prime mover 25, and the belt feeder is rotated. The belt of 9 and the cam 16 of the striking device 14 rotate.

At this time, as shown in FIG. 1, when the paper container assembly 4 unfolded and fixed to the box 5 from the conveyance path is sequentially sent over the conveyance path, the mother-floor which falls sequentially from the tip of the belt feeder 9 It is supplied and laminated on paper container aggregates (4) in an acid form. In addition, since the paper container assembly 4 is conveyed to the right side in the drawing by the rotational movement of the roller 3 on the conveyance path while supplying the bed soil, the upper surface of the paper container assembly 4 is sequentially passed through the conveyance path. The ridges of the base plate soil in which the bars 13 are installed are thinly cut and broken down to make the top surface flat. At this time, the bar 13 hits the ridge to the back of the plate like a flat plate to leave the extra soil flat to leave the excess, do not discard the excess, thinly crushed the ridge to flatten the rest so that the rest behind the bar (13) Does not build up the soil.

On the other hand, when the box (5) reaches the striking device (14) when the box (5) reaches the flat surface according to the bar (13) will be beaten to the striking body (18) by alternating the bottom side left and right, but both sides of the top surface Pressurization by the pressure roller 21 prevents the box 5 from floating, and thus only the vibration caused by tapping is transmitted to the paper container assembly 4 in the box 5, and the mother soil supplied in accordance with this vibration is supplied. Dense and settle down without scattering around. Then, the left and right according to the rotational motion of the rollers (3a) and rollers (3b), by the primary voltage roller (11), the secondary voltage roller (12) the mother soil on the upper surface of the paper container aggregate (4) It is pressurized and it presses in each paper container assembly powder.

Pressurization by the secondary voltage roller 12 causes the outer circumferential surface of the voltage roller 12 to come into contact with the upper surface of the paper container assembly 4, so that the sidewall of the box 5 having the same height as the paper container assembly 4 is provided. Since the silver is as high as the thickness of the comb (6) fixed by engaging the paper container assembly (4), the drop of the width of the comb (6) is reduced to the secondary voltage roller (12) and the corresponding pressure roller from the bottom. The secondary voltage of the comb 6 engaged with the side wall of the box 5 in such a way that the central axis of the roller 3b constituting it is shifted back and forth in the conveying direction so that the maximum diameter main surface of the corresponding roller does not touch the flowerpot. Allow passage of the roller 12 portion.

Further, the mother soil is pushed into the paper container assembly 4 by the secondary voltage roller 12, and then scraped off by the auger 22 with respect to the extra soil that slightly covers the upper surface thereof. 4) When the feeling of lack of firmness of the bed soil on both sides is insufficient, the auger 22 may be scraped off only at the center, and extra soil may be collected at both sides and left. Subsequently, when the upper surface is suppressed by the voltage roller 23, but the extra dirt is gathered on the side circumference, these extra dirt is press-fitted in each paper container assembly.

The present invention is a belt type feeder (9) to a paper container assembly pot (4) fixed by engaging with the comb (6) to the box (5) or the board (7) in filling the bed soil of the paper container assembly pot (4) The bed soil supplied to the) is flattened by flattening the ridges, such as thinly picked by the bar 13, and no dirt remains as in the rear of the bar 13 when the bed soil is cut with a flat plate. And the paper container assembly 4 which unfolded on the board | substrate 5 which made the board | substrate evenly, or the board | substrate 7 presses both upper surfaces with the pressure roller 21, and conveys both sides of the lower surface of the box 5 to a conveyance path. Since two hammers (18) of the striking device (14) provided on the back side are alternately beaten, the vibration of the paper container assembly (4) can be applied evenly without floating the box (5). As a result, the bed soil easily forms an intimate layer.

The paper container by disposing the primary voltage roller 11 and the secondary voltage roller 12 so that pressurized soil is tightly pressed by approaching the outer circumferential surface of the lower rotary motion part of the belt-type feeder 9 in order to pressurize the mother soil compacted by such vibration. The bed soil on the upper surface of the aggregated pot 4 is press-fitted into each paper container pot, and the filling strength of the bed soil of the paper container aggregate pot 4 in which the bed soil is uniformly and tightly pressed is extremely good.

Moreover, the axial center of the secondary voltage roller 12 and the roller 3b allows passage of the comb 6 which develops and fixes the paper container assembly 4 to the box 5 back and forth in a conveyance direction. Since the gap is shifted by the interval, the pressurizing of the bed soil in the paper container assembly 4 by the secondary voltage roller 12 is performed to the height of the paper container assembly 4, thereby allowing the passage of both ends of the box 5 to pass. Makes it possible to run without interruption.

In addition, the auger 22 scrapes the extra soil left on the upper surface of the paper container assembly pot 4 press-pressed the mother soil with the secondary voltage roller 12, but at this time the auger 22 scrapes Only the central part is thrown out, and the leftover soil is scraped on both flower pots and then pressed by a voltage roller 23 to compensate for the lack of filling firmness of the bed soil on both sides of the paper container assembly pot 4. have.
