Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seedling processing machine for untangling roots of seedlings.

[0002]

[Prior art]

 Conventionally, when the roots of the seedlings to be transplanted are strongly intertwined, in the seedling processing machine that is unraveled before transplantation, a large number of tines that stick into the roots of the seedlings are projected on both sides of the seedling transport route at intervals in the vertical and longitudinal directions. In the seedling processing machine, which has the above-mentioned conveying belts arranged oppositely and unwinds the roots by swiveling the tines while sandwiching and transporting the seedlings, a plurality of end pieces are connected at intervals in the calyx direction of the seedlings. A guide body such as a guide rod of a book or a guide plate having a plurality of guide grooves is provided so as to be opposed to the transfer belt so as to sandwich and guide the seedlings, and at the end of the transfer, the root is received and removed from the tines. Is already known.

[0003]

[Problems to be solved by the device]

 Since the tine of the known seedling processing machine is extremely dangerous because it is formed into a needle shape so that it can be pierced into a solidly entangled mass such as the root of strawberries, it is extremely dangerous. The guide body was housed in the case. Then, during rooting work, the tines come out between the guide rods of the guide body or from the guide groove while the roots are hooked, so that root debris accumulates at the end of the groove and becomes a lump, and in this state the tines Caused the lump to come out while pressing the lump, which overloaded the carrier and the tine, and damaged the tine. Moreover, as mentioned above, it was extremely difficult to remove the lumps of lumps from the opening at the end of the case. When the rear end of the guide groove was opened to solve such a problem, the narrow band-shaped plate forming the guide rod or the guide groove was easily bent, and the amount of bending between the upper and lower parts was Because of the difference, the width of the guide groove was enlarged, and the root waste was carried around by the tines, and the desired root waste receiving effect could not be obtained.

[0004]

[Means for Solving the Problems] The present invention comprises, on both sides of a seedling feeding path, a plurality of tines that stick into the roots of seedlings and are provided with a pair of feeding belts projecting vertically and longitudinally at intervals. In a seedling processing machine that unwinds roots by a swiveling operation, the transfer belt is stretched in a case having an opening at the front and back, and the tines enter the seedling transfer route side of the transfer belt. A plurality of guide grooves that move in parallel with each other are provided at upper and lower intervals, respectively, and the respective winding prevention guides are arranged. Above the winding prevention guide, the end of the guide groove is closed. The above-mentioned problem was solved by extending it outside the case and opening the end of the guide groove at the lower end.

[0005]

[Action]

 When a group of seedlings with entangled roots was fed from the opening on the feed side of the seedling processing machine to the beginning of the left and right conveyor belts, the roots entwined with many tines protruding from the conveyor belt were stuck from both sides. , The tine that moves in the guide groove of the guide body sequentially turns at the traveling part of the conveyor belt, so that the entangled root is forcibly released, and when the tine turns while exiting from the root portion at the end of the conveyor belt, , The root is received by the guide groove and scraped off. At this time, the cut waste roots are caught in the guide groove, but the guide body extends to the outside of the case, so it is pushed out of the turning range of the tines, so there is no obstacle to circulation, and the waste roots are removed. In this case, it can be easily removed outside the case, and since the rear end of the guide groove at the lower end is open, it easily separates and falls. Furthermore, since the end of the guide groove on the stem side is connected, the guide body can be firmly formed to improve the scraping performance, and both sides of the groove do not move relatively, so it can be carried around easily. It can be prevented.

【Example】

 An embodiment of the present invention will be described with reference to a seedling processing machine 1 for strawberries in the drawings. A substrate 4 is tilted and fixed on a machine base 3 having a caster 2, and a main unwinding device is provided on the upper surface side. 5 is provided, and an auxiliary unwinding device 6 is provided on the lower side, and a pair of left and right conveying bands (chains) 7 and 7 are formed at the seedling introduction port 8 with the upper part separated and the lower part is brought closer. The tension sprocket 7a and the tension guide 7b are interposed between them so as to form a V shape as a whole.

The chain 7 is wound around a drive sprocket 9 and a driven sprocket 10, and the sprockets 9 and 10 are respectively driven by a drive shaft 11, which is rotatably supported between the substrate 4 and the case 4a. And is fixed to the driven shaft 12. The output pulley 13a of the motor 13 of the auxiliary unwinding device 6 drives the input pulley 14a of the speed reducer 14 via the belt 15, and the output sprocket 16a attached to the output shaft 16 of the speed reducer 14 is provided with the tension sprocket 17a. The fixed sprocket 11a of the drive shaft 11 is driven via the chain 17 thus formed. In addition, on the outer circumference of each chain plate 7c of the chain 7, three tips were sharpened so that the roots entwined with the strawberries seedlings fed from the seedling introduction port 8 could be pierced from both sides to rotate. Each of the comb tooth bodies composed of the tines 18 is attached.

Guide plates 19 having upper and lower three guide grooves 19b and 19b ′ into which the tines 18 enter and move are arranged on the conveying action side of the chains 7 and 7, respectively. The seedling introduction port 8 side of the guide plate 19 is supported by fitting a boss 19a fixed thereto to a bolt or pin projecting on the base plate 4, and the seedling discharge port 22 side of the guide plate 19 is gradually widened. A U-shaped connecting member 19c, which is bent so as to be fixed to the upper and lower outer surfaces, straddles an elongated guide member in the middle, and a lower portion is screwed to the substrate 4.

The end portion of the guide plate 19 projects from the case 4a as shown in FIG. 3, and the end portions of the two guide grooves 19b and 19b on the stalk side are formed by connecting a guide member. A guide member 19g which is closed and forms the lower edge of the lowest guide groove 19b 'is cut out near the carrying-out side of the connecting member 19c and opened as shown in FIG.

As shown in FIG. 5, swash plates 20, 20 are provided on the left and right sides of the case 4 a at a portion corresponding to the seedling introduction port 8. If the diameter of the root stock of the supplied strawberries is greater than the specified width (limit width) h, the passage will be blocked. Guide plates 21 and 21 are arranged continuously in parallel from the lower ends of the swash plates 20 and 20 with a predetermined distance therebetween, and the lower ends of the guide plates 21 and 21 are open in a V shape toward both sides. Is formed.

A pair of upper and lower pulleys 26, 26, 27, 27 which rotate by receiving power from pulleys 25, 25 mounted on the driven shafts 12, 12 are provided in front of the chains 7, 7 and the tines 18, 18. By the foliage conveying belt 28 which is pivotally supported and wound around these pulleys 25, 26, 27, the roots of the strawberries are stabbed and moved by the chains 7, 7 and the tines 18 ... I am doing it. On the rotating shaft 27a of the pulley 27, that is, on the conveying end side of the foliage conveying belt 28, PVC seedling locking members 29, 30 for correcting the releasing posture of the seedlings are arranged. The seedling locking members 29 and 30 are both disc-shaped, and the diameter of the seedling locking member 29 is larger than that of the seedling locking member 30. In addition, a scraper 31 made of an elastic material, one end of which is fixed to the case 4a and whose tip is brought close to the belt groove of the pulley 27, is provided for removing seedlings.

On the other hand, on the side of the auxiliary unwinding device 6, in synchronization with the movement of the chains 7, 7 and the tines 18, 18, ... Three separator claws 32 are provided which draw a predetermined tip locus R from the opening 4b and operate in the front-rear direction so that the root stock of the strawberries can be uncoiled from the root side. This separator claw 32 is detachably attached to a claw holder 32a fixed to the tip of a separator arm 33, and a crank arm 34 and a swing arm 35 are attached to the separator arm 33. The power is transmitted to the rotary shaft 34a of the crank arm 34 from the input shaft to which the input pulley 14a of the speed reducer 14 is fixed, via the chain transmission system 36. On the front surface of the separator claw 32, comb tooth-shaped rooting preventive devices 37, 37 are provided so as to cover the upper and lower portions of the tip locus R of the separator claw 32.

If the moving timing of the tines 18, 18 ... And the separator claw 32 is too early, the separator claw 32 will come into contact with the tine 18 to cause a damage accident, and if it is too late, the performance of releasing the rootstock of the strawberries seedlings will be improved. When the tip of the separator claw 32 protrudes slightly (about 5 mm) from the opening 4b, the left and right tines 18 are made to substantially coincide with each other and are approached by about 3 to 5 mm. I tried to become.

Next, the operation of the seedling processing machine 1 will be described. When the motor 13 is started, the drive shafts 11 and 11 rotate via the speed reducer 14, and the V-shaped chains 7 and 7 and the tines. 18 ... Rotates. At the same time, the foliage conveying belt 28 and the seedling engaging members 29, 30 rotate, and the crank arm 34 and the swinging arm 35 rotate the separator arm 33 in the front-rear direction, so that the tip of the separator claw 32 moves along the locus R. Draw and rotate. In this state, the seedling population of strawberries is supplied to the seedling introduction port 8 in a state in which the root stock corresponds to the tine 18 and the foliage corresponds to the foliage conveying belt 28, respectively. At this time, when the diameter of the root stock portion of the strawberries is larger than the predetermined dimension width h, the passage is blocked by the swash plates 20 and 20. In such cases, the straw seedlings are divided by hand into small diameters and then supplied.

The strawberries seedlings supplied from the seedling introduction port 8 are forcibly nipped and conveyed by the left and right foliage conveying belts 28, 28, and the entangled roots are conveyed obliquely downward in the V-shaped chain 7 , 7 protruding from the guide plate 19 and penetrating into the guide groove 19b of the guide plate 19 penetrates deeply into the root stump at the portion that moves linearly, and the trailing ends of the chains 7 and 7 The roots are widened by the turning of the tines 18 ..., so that the roots are rooted. Then, the tines 18 ... Retreat from the guide grooves 19b, 19b 'in sequence.

At this time, the cut roots caught on the respective tines 18 are received by the narrow strip-shaped guide members forming both side edges of the guide grooves 19b, 19b ′, but the upper two guide grooves 19b, Since the ends of 19b are connected in series, the above-mentioned both side edges do not cause relatively separate bending due to the difference in load, and therefore, the groove width is hardly expanded and the cut root is not cut. You can surely scrape off the tine 18. The cut root thus scraped off is gradually drawn downward in the guide grooves 19b, 19b and is accumulated at the terminal end, but the end of the guide plate 19 is obliquely downward from the case 4a. Since it is extended to the tine 18, it can be quickly removed in a safe state in which the hand does not touch the tines 18 ..., And in a state in which the case 4a does not become an obstacle. Further, although the ends of the upper two guide grooves 19b, 19b are closed, they are largely separated from the turning position of the tine 18 ,. It does not become an obstacle when doing. Further, since the strip-shaped guide member 19g forming the lower edge of the lowermost guide groove 19b is cut off near the delivery side of the connecting member 19c to open the end of the guide groove 19b ', a cutting root is formed at the lower part. It occurs most often, but it can be easily discharged to the outside of the aircraft.

FIG. 6 shows another example of the caster 2. A set of casters 2 and 2 on one diagonal line is freely horizontal with a vertical support shaft as the center as in the conventional casters. The casters 2a, 2a, which are supported so as to rotate but which are arranged on one other diagonal line, are rotatable, but are 45 degrees with respect to the machine base 3 having a quadrangular shape in plan view as shown. It is fixedly supported (does not rotate horizontally) so as to maintain an inclined posture, and when the seedling processing machine 1 is moved, if there is a step on the floor surface, the rolling direction of the casters 2a, 2a that does not rotate horizontally When the casters 2 and 2 that turn horizontally are pushed forwards and backwards, the first caster 2 located at the front rides on the step and when the seedling processing machine 1 is tilted, the gap between them is set. Of adjacent casters 2, 2a Since it is larger than the interval, the center of gravity of the machine does not come off from the rear caster 2 and it can be moved in a state where it is difficult to lay down, and then it is easy and safe by pushing up the casters 2a, 2a that do not horizontally turn left and right. It is possible to get over a step.
