Description

  In particular, the present invention relates to a cutting apparatus suitable for an operation of cutting to an appropriate size when planting potato seed pods.

  In general, since a relatively large number of shoots germinate on the surface of a potato seed pod, the seed pod is cut into an appropriate size, and one or several shoots are left on each cut piece of seed pod.

Conventionally, as an apparatus for efficiently cutting seed pods, an endless conveyor is used, and one or several blades are dropped from above onto the seed pods conveyed by the conveyor belt, and cut into a plurality of pieces. Is known (for example,
, ).

  In these conventional cutting apparatuses, when the seed potatoes are placed on the transport conveyor, they are transported without being particularly fixed only by positioning using a support tool that is depressed in the center. And when it is transported to the end of the conveyor, when the conveyor belt reverses, it falls from above the support into a receiving box provided below by gravity.

  However, since the seed candy is not fixed on the conveyor, it is easy for the operator to perform the loading operation. On the other hand, when the seed potato is cut by the blade, the seed potato sometimes jumps to the side. In addition, since the cut seeds are configured to drop into a receiving box prepared below from a relatively high position of the conveyor, there is a large drop with the conveyor, and the seeds vigorously enter the receiving box. There was a problem of falling and crushing new shoots or removing new shoots.

This kind of trouble was caused by mechanically grasping or releasing the seed pod as a means for fixing the seed pod. The seed potato was fixed before cutting the seed potato, and the seed potato was carried to the lower side of the conveyor by the conveyor belt. It is improved by throwing it into the receiving box from a low position, sometimes releasing it. However, since the individual seed pods are not uniform in size, shape, and germination position, it is difficult to make a holding device that can hold the seed pods in accordance with the outer shape of the seed pods, and it is likely to be expensive.

  The problem to be solved is that when the cutter cuts the seed pod, the seed pod is stably held on the conveyor belt even if the shape and size of the seed pod are not uniform. To obtain a low-cost apparatus that can be stably transported to a low position on a belt conveyor and can be accurately dropped on a receiving box.

  In the present invention, a conveyor belt provided with seeding fixing means is wound between a driving roller and a driven roller to form a seeding conveyor, and the seeding feeder is disposed upstream and downstream of the conveyor. A tool insertion part for raising and lowering the blade, and a lifting means for raising and lowering the blade on the conveyor belt above the knife insertion part. A fixing means is configured by implanting an upward nail member on the conveyor belt. In addition, it is most important to install a scraping plate for pulling seeds away from the fixing means, and a space for the receiving box located below the scraping plate, located on the return side of the conveyor belt. Features.

  In this case, it is preferable that the escape groove is formed as a groove slightly larger than the shape of the blade edge of the blade in the forward direction of the blade, and the fixing means is constituted by nail members planted on both sides of the escape groove. Further, the cutter and the relief groove may be prepared as a pair of three, two, three, and four having an axis parallel to the advancing and retreating direction of the cutter and extending radially from the axis. .

  The seed slicing device according to the present invention is such that when the seed sword transported from the insertion part to the sword insertion part is cut by the blade, the cut individual pieces are held in place by the nail member. They are not scattered on the conveyer or scattered outside the conveyer, and the device itself and the periphery of the device can be kept hygienic.

  In addition, the seed pod is transferred to the lower surface of the transport conveyor while maintaining the position and posture at the time of cutting, and is removed from the nail member by a scraping plate at a low position, so that the drop with the receiving box is small. In this case, it is possible to minimize the problem of damaging the sprout during the fall.

  Furthermore, the seed vat fixing means is constituted by a conveying plate having a relief groove and nail members planted on both sides of the relief groove, the fixing operation is easy, and the cutting device The structure is not complicated. In addition, the fixation of the seed pod to the fixing means requires a simple operation of simply placing the seed bud on the nail member in consideration of the position of the bud of the seed potato, pressing it from above, and piercing it.

  Hereinafter, the illustrated embodiment will be described. In FIG. 1, reference numeral 10 denotes a cutting device for seed potatoes according to the present invention. The cutting device 10 includes a frame 12 assembled by welding equilateral angle steel, a transport conveyor 20 supported at the center of the frame 12 in the vertical direction, and a cutter for cutting seeds onto the transport conveyor 20. Elevating means 14 for supporting and elevating 38 is included. Further, the lower surface of the frame body 12 is supported by two each of a caster wheel 17 and a fixed wheel 18 that linearly travels, so that the frame body 12 can be easily moved.

  The conveyor 20 is a so-called endless belt conveyor, and a conveyor belt 23 is wound between a driving roller 21 and a driven roller 22. The upstream side in the transport direction protrudes laterally from the frame body 12 to form a seeding throwing portion 15, and the downstream side located below the lifting and lowering means 14 is for cutting seeds with a blade that descends from above. The sword insertion part 16 is a space. The frame 12 is provided with a space for receiving the seed box 24 that is located below the conveyor 20, and a container made of synthetic resin as the receiving box 24 is stored therein.

  As shown in FIG. 2, the main part of the conveyor 20 is supported by the left and right side plates 25, 25 attached to the frame body 12, and the drive supported by bearing units 26, 26 attached to the side plates 25, 25. The roller 21, the driven roller 22, and the conveyance belt 23 are included. Reference numeral 27 denotes a support shaft of the driving roller 21 and the driven roller 22, and the support shafts 27 and 27 are left and right roller chains welded to the back surface of the conveyor belt 23 by left and right sprockets 28 and 28 fixed in the vicinity of both ends. 29 meshes.

  The left and right roller chains 29 and 29 are connected to an electric motor 30 with a speed reducer via a support shaft 27. The electric motor 30 is controlled by a control panel (not shown) so that the seeds to be conveyed support the cutter. When it comes directly below the means 14, the conveyor belt 23 is intermittently driven in such a manner that it temporarily stops. Although the above configuration and functions are slightly different from those of the conventional apparatus, there is no great difference.

  In the present invention, the elevating means 14 is temporarily engaged with an arm member 42 driven by an electric motor 41 with a speed reducer, a suspension arm 43 lifted by the arm member 42, and a position where the suspension arm 43 is lifted. The lifting / lowering means 14 is connected to the blade 38 via a lifting / lowering shaft 45 arranged in the vertical direction. Therefore, the lifting / lowering means 14 is related to the operation of the conveyor belt 23 and drops the blade 38 at the position where the conveyor belt 23 is temporarily stopped.

  As for the raising / lowering means 14, the arm member 42 rotates from the state and the suspension arm 43 is lifted by the cam surface 42a provided in the arm member 42. When the suspension arm 43 is lifted to a predetermined position, the lower end surface thereof is supported by the electromagnetic hook 44, and at the same time, the arm member 42 returns to the original position and stands by until the next operation. Then, when the conveying plate 23b on which the seed potato is placed stops just below the blade 38, the electromagnetic hook 44 is retracted and disengaged, the suspension arm 43 falls by gravity, and the seed potato is divided into a predetermined number. It is like that.

  Next, the conveyance belt 23 will be described. The conveyor belt 23 is configured by connecting the left and right roller chains 29, 29 by a steel plate connecting plate 23a, and a synthetic resin transport plate supporting seeds on the connecting plate 23a. 23b is attached in piles.

  The transport plate 23b has a strip shape with a thickness of about 10 mm. On the upper surface of the transport plate 23b, as shown in FIG. 3, there is a relief groove 31 for preventing the blade 38 descending from above and the transport plate 23b from colliding with each other and a seed rod. A nail member 32 for fixing is provided. The transport conveyor 20 is set so that the transport is temporarily stopped at a position where the center in the width direction of the transport plate 23 b is on the axis of the lifting shaft 45.

  Each escape groove 31 is provided at the position where the seed tub is placed. For each conveyance plate 23b, three pairs are provided, one on the axis of the lifting shaft 45 and one on each side. ing. The position where the soot is placed is a center 31a vertically lowered from the virtual center of the soot to the transport plate 23b, and the escape groove 31 is an I-shaped groove constituted by two grooves extending radially from the center 31a. 31b, a Y-shaped groove 31c composed of three grooves, and a cross-shaped groove 31d composed of four grooves. Therefore, the three pairs of escape grooves 31 are arranged in a direction orthogonal to the transfer direction of the transport conveyor 20.

  The nail member 32 as the fixing means is made of a thin hard steel wire having a diameter of about 2 mm, and has a pointed tip as necessary. Then, as shown in FIG. 6, at least one nail member 32 is inserted into one of the cut pieces of the seed pod, and is planted outside each escape groove 31.

  In order to fix the seed pods to the nail member 32 arranged in this manner, when the number of shoots of seed pods is two, the shoots are placed on both sides of the groove of the I-shaped groove 31b, and the nail members 32, Place on top of 32, push down and insert into nail members 32, 32. Similarly, when the number of new shoots is three, the three new shoots are inserted into the nail members 32 and 32 so as to sandwich the Y-shaped groove 31c. Similarly, when the number of shoots is 4, it is fixed at the position of the cross-shaped groove 31d. The blade 38 has a vertical axis parallel to the axis of the elevating shaft 45 from the center 31a of the escape groove 31, and, like the escape groove 31, extends two, three, and radially from the axis, and 4 pieces

  Reference numeral 35 denotes a scraping plate installed on the return side of the conveyor belt 23, i.e., below the conveyor 20. The scraping plate 35 is provided for pulling the cut seeds conveyed by the conveying belt 23 away from the nail members 32, 32 as fixing means and dropping them into the receiving box 24.

  Next, the operation of the cutting device 10 will be described. Since the conveyor 20 moves and stops once when it reaches a predetermined position, the operator puts the soy seed on the nail member 32 as a fixing means provided on the conveyor plate in the upward position in the loading unit 15. And put it in. The conveyor 20 continues to move a predetermined distance and repeats this stopping operation.

  When the soot inserted into the nail member 32 reaches the sword insertion portion 16, the cutter 38 descends from above while the transporting conveyor 20 is stopped, and cuts the soot. At this time, even if the soot is cut, it is fixed by the nail member 32, so that it stays on the conveyor belt 23 and does not fall to the periphery.

  When the conveyor belt 23 rotates around the circumference and the cut soot reaches the lower side of the transport conveyor 20, the seed sow comes into contact with a scraping plate 35 installed there, and further movement is prevented. It falls out and falls into the receiving box 24 placed below by gravity.

It is the front view which carried out the cross section of a part which shows the cutting device of a soot seed. It is an expanded sectional view which shows the II-II cross section in FIG. It is an external view which takes out and shows the principal part of a conveyance conveyor. It is an external view shown by arrow IV in FIG. It is VV sectional drawing in FIG. It is a top view of the conveyance board shown by arrow VI in FIG.
