Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting machine for planting seeds such as various root crops and bulbs. Conventionally, various root crops, bulbs and the like have been cultivated as food or ornamental crops. In all of these bulb vegetables, nutrients are stored in roots, stems, leaves, and the like existing in the ground, and the nutrients grow in a spherical or massive form. Therefore, the spherical or massive portion is dug up from the ground and harvested for use in eating or appreciation. In addition, when cultivating, including appreciating flowers and the like, it is necessary to replant a spherical or massive portion dug from the ground as a seed. When the cultivation area is large, a machine for planting seeds is used in consideration of reduction of labor burden and improvement of planting efficiency. [0003] Such seedling planting machines for bulbous vegetables generally include a cultivator for forming a groove for planting seeds in a main body frame provided with wheels, and a covering disk for covering the seeded potatoes with soil. A rake hopper for storing seedlings for planting, a spoon belt for transporting picked up potatoes, and a loading cylinder for sowing seeds that have been transported in a groove to form a seed supply path. Is installed. The rake hopper has a seed opening that is widely open at the upper end, and a seed opener that has a small opening at the lower end. Attach a tube. In addition, a spoon belt is provided with a large number of spoons that pass through the inside of a rake cylinder to scoop up seeds and convey the spoons at substantially equal intervals along an endless belt body that receives a driving force. The loading cylinder is arranged along the belt body below the vicinity of a turning point of the spoon belt body from the rising direction to the descending direction or from the horizontal direction to the descending direction, and accommodates a plurality of spoons therein. In addition, the discharge port of the charging cylinder is disposed immediately above the planting groove. [0005] At the time of planting, an appropriate amount of seed is put in the body of the rake hopper of the seed planter and the planter is run. Then, the seed potatoes sequentially fall into the rake cylinder through the discharge port of the hopper body. Therefore, the potatoes are picked up by a spoon that sequentially passes through the inside of the rake cylinder, transported upward, and then dropped from the discharge port of the input cylinder. Therefore, seeds can be planted by sowing them in the grooves formed by the cultivator and covering them with the disc. [0006] However, seeds to be planted by such a planting machine have various shapes and sizes. Therefore, two or more seeds fall into the inside of the rake cylinder and fall side by side, sometimes being pinched tightly, cannot be picked up with a spoon, and the belt cannot rotate. Although round seeds have few problems, problems are likely to occur when one seed is cut into two or more pieces like potatoes. At that time, the seedling must be removed from the inside of the rake cylinder by stopping the planting machine, turning the belt slightly in the opposite direction, moving the spoon downward, and piercing with the tip of a rod. It should be noted that if the rod is pierced with the tip of the rod, the seed is naturally damaged, and even if the spoon scoops up a thing that is tightly sandwiched inside the rake cylinder, excessive force is applied, and the seed is easily damaged. [0007] Also, the seeds picked up vertically from the rake hopper ride on a spoon, and are further conveyed in the ascending direction by a replenishing passage arranged in a lateral direction with a slight inclination.
Fall into the charging cylinder. At that time, a large centrifugal force acts on the seed on the spoon at the turning point of the spoon belt body from the rising direction to the falling direction. Therefore, the seed potatoes may be thrown out of the spoon and fall out of the loading tube. For this reason, a seedling receiving cover is attached near the upper end of the charging cylinder so that it falls into the charging cylinder. However, when removing one of the two seeds on the same spoon or the like, an operator's hand may be caught between the cover and the spoon, resulting in injury. Also, the seeds thrown out of the spoon may be caught between the tip of the spoon and the bottom wall of the charging cylinder, and the belt may not rotate. At that time, the planting machine must be stopped and the seeds must be removed, causing the seeds to be damaged. The present invention has been made in view of such a conventional problem, and firstly, a seed that falls into the inside of a rake cylinder from a discharge port of a rake hopper body and is transferred to a spoon. Equipped with a potato delivery tool to prevent the seeds from being caught in the rake cylinder, so that the seeds are not damaged, the spoon belt rotation stop accident does not occur during planting, the soil attached to the seeds, etc. An object of the present invention is to provide a bulb vegetable seedling planting machine capable of smoothly performing a scooping operation without hindering a transfer operation. It is a second object of the present invention to provide a bulb vegetable planting machine capable of scooping up more smoothly in addition to the first object. Means for Solving the Problems In order to achieve the above object, in the bulb vegetable seedling planting machine according to the first object of the present invention, the inside of the rake cylinder is always in a rake cylinder. A receiving part that protrudes so as to close and receives the falling seed is arranged slightly below the discharge port of the hopper body, and a seed that has a receiving part that recedes when a spoon hits is provided. At least two bent rods having a seed receiving portion are arranged at a distance from each other, and both ends on the receiving portion side are connected by using members, and the end connecting member is scooped through a tension coil spring. It is connected to a cylinder, and it is rotatably formed by connecting both ends on the other side to a shaft supported by a rake cylinder, and the center part of the transfer tool is inserted into the inside from the window opened in the rake cylinder wall It is characterized by doing. Further, the seedling potato planter for bulb vegetables corresponding to the second purpose is characterized in that the two seeding tools are arranged symmetrically inside the rake cylinder. Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view from the inside (left side) showing an example of a seed pottery transfer tool installed in a rake cylinder of a potato seedling plant for pulling bulb vegetables to which the present invention is applied, and FIG. 2 is the pulling bulb. It is the perspective view seen from the left side of the vegetable seedling potting machine. In the figure, 10 is a potato planter for bulbous vegetables for a walking type tractor, 12 is a box-shaped main body frame which forms the center of the frame, 14
(14a, 14b) are left and right iron wheels provided on the lower side of the body frame 12 near the rear,
Reference numeral 16 denotes a coupler with a walking type tractor provided on the front side of the main body frame 12, reference numeral 18 denotes a cultivator provided near a joint of the coupler 16 with the main body frame 12, and 20 (20a, 20b).
Are left and right earth covering disks provided on the rear side of the main body frame 12. Each of these wheels 14 is provided with a large number of square iron claws 22 on the outer peripheral surface.
Therefore, when the seedling planting machine 10 is towed by the walking tractor, each of the claws 22 bites the soil, and both wheels 14 rotate well without slipping on the soil. Therefore, a sprocket 26 is provided on a rotating shaft 24 connecting the two wheels 14, and the sprocket 2
6. A chain 28 is wound around 6, and a driving force for seed supply is obtained. Further, since the connecting position of the connecting device 16 and the walking type tractor can be selected, and furthermore, the cultivating device 18 can select the connecting position with the main body frame 12, the depth of the planting groove formed by the cultivating device 18 can be adjusted. In addition, both the covering discs 20 can adjust the depth of the disc with respect to the ground and the angle of the disc surface with respect to the running direction. Further, in order to form a seed supply path at a position near the front of the main body frame 12, a rake hopper 30 for storing planting seeds, a spoon belt 32 for conveying the picked seeds, and the like are conveyed. An input cylinder 34 for sowing seeds in a groove is installed. The rake hopper 30 is substantially funnel-shaped as shown in FIG. 3, and has a large rectangular opening for seed feeding port 36 at the upper end, and a small, approximately two-thirds lower end.
A hopper body 40 having a circularly opened seed discharge port 38 and a seed rake cylinder 42 communicating with the discharge port 38 provided below the hopper body 40 and having the same diameter as the discharge port 38 are provided. Then, the rake cylinder 42 has two kinds of transfer tools 44 (as shown in FIG. 1).
44a, 44b) are arranged and provided so as to be symmetrical in the front-rear direction inside the rake cylinder 42. [0013] All of these seed delivery tools 44 are horizontally arranged seed receiving portions 46.
Two round rods 48 of the same shape bent at an acute angle and having a
Both ends of the receiving portion 46 side are connected using a plate-shaped member 50, and the end connecting member 50 is connected to the outer wall of the upper end portion of the rake cylinder 42 via a tension coil spring 52,
Both ends on the other side are connected to a shaft 54 supported by an outer wall near the lower end of the rake cylinder 42 to be rotatable. The center of the transfer tool 44 is inserted into the interior 58 through a window 56 opened in the wall of the rake cylinder 42. In this manner, the delivery tool 44 is installed in the rake cylinder 42, and is protruded so as to always close the inside 58 of the rake cylinder 42.
When the seed potato 60 is disposed at a lower position, it can be received when the seed potato 60 falls into the rake cylinder 42 and a part thereof enters. Therefore, the seed potato 60 is a rake cylinder 42
It does not penetrate deeply into the interior of the device. Moreover, the soil or the like that has adhered to the seed potato 60 is easily dropped because the receiving portions 46 are arranged in a bar shape and a gap is formed. Then, when the spoon 62 is raised from below the inside of the rake cylinder 42, the edge of the spoon 62 hits the lower end of the rod 48 forming the delivery tool 44. Then, the rod-like body 48 resists the urging force of the tension coil spring 52, rotates about the shaft 54, and the receiving portion 46 retreats. Therefore, the seed potato 60 on the receiving portion 46 can be scooped up smoothly with the spoon 62. In particular, when the two transfer tools 44 are arranged so as to be symmetrical in the front-back direction inside the rake cylinder 42, both edges of the spoon 62 abut against the lower ends of the transfer tools 44. As a result, the potato 60 can be placed on the center of the spoon 62 and can be scooped up more smoothly. The flange 64 provided at the upper end of the rake cylinder 42 is a place where the hopper 40 is screwed to the hopper body 40. [0016] A plurality of spoons 62 for scooping up and transporting the seed potion 60 passing through the inside of the scooping cylinder 42 and being arranged at substantially equal intervals along the endless belt body 66 receiving the driving force are provided. Is a spoon belt 32, and a large number of spoons 62 are vertically fed by a belt body 66 stretched in a triangular shape, a horizontal feed group slightly raised in a horizontal direction, and a diagonal feed group lowered in an oblique direction. Divided into When the seeds 60 are replenished, the spoons 62 belonging to the vertical feed group all move inside the rake hopper 30 along the center of the inner wall surface and near the wall surface. Further, the spoons 62 belonging to the lateral feed group all have guide plates 70 (70a) with guide rods 68 (68a, 67b) provided on both sides so that the seeds 62 do not drop.
, 70b), and moves away from the rake hopper 30 on the right side of the main body frame 12 right to the left. Note that spoons belonging to the horizontal feed group may be sent in the horizontal direction. In addition, the spoons 62 belonging to the oblique feed group move from the upper left so as to approach immediately after the cultivator 18. Incidentally, the spoon 62 is a spoon-shaped iron plate coated with rubber, and the belt body 66 is made of rubber. The spoon 62 belonging to such an oblique feed group is accommodated by covering the spoon 62 from the lower side with the loading cylinder 34 having a substantially two-thirds circular cross section, which is downward from the rising direction of the belt body 66 or horizontally. It is arranged from a position slightly above the turning point toward the downward direction from the direction downward, and the discharge port 72 at the lower end thereof is arranged near the planting groove near the planting groove. Then, as shown in FIG.
A seed delivery tool 78 having a large elastic plate 76 made of, for example, a plastic resin, which receives the released seed 60 by lightly contacting the tip of the spoon 62 located at the turning point of the belt main body 66 inside the belt. Install. Then, a large centrifugal force acts on the seed potato 60 conveyed by the spoon belt 32 at the turning point,
Even if the seed potato 60 is thrown out, the seed potato 60 can be softly received by the elastic plate 76, dropped into the loading tube 34, and then sent on the back of the spoon 62. At this time, since the tip of the spoon 62 and the elastic plate 76 are in contact with each other, the seed potato 60 does not get caught between the tip of the spoon 62 and the bottom wall of the charging cylinder 34. In particular, one end of a rectangular seed receiving elastic plate 76 that contacts the tip of the spoon 62 at the center in the longitudinal direction contacts the bottom wall of the loading cylinder 34 and the other end of the elastic plate 76 is loaded. One end is fixed to the bottom wall of the cylinder 34 and supported by the other end of a bendable, for example, metal support plate 80 of a rectangular shape having a fixed end. It is preferable to provide the seed pottery delivery tool 78 by providing the same. Because the spoon 62 is arranged so as to be wound in a substantially arc shape by the elastic plate 76, the thrown potatoes 60 can be well received on the arc surface of the elastic plate 76, and can be quickly placed on the back of the spoon 62. This is because they can be carried. When changing the tension of the spoon belt 32, the shaft 86 of the belt guide pulley 84 that supports the belt main body 66 at the turning point by loosening the thumb screw 82 is moved. This is because the bent state of the support plate 80 can be changed in accordance with the movement, and the position of the elastic plate 76 can be changed so as to lightly contact the tip of the spoon 62. In addition, belt guide pulleys 88 and 90 are respectively installed at each turning point of the belt main body 66 from the obliquely descending direction to the vertical direction and from the vertical direction to the horizontal direction. Then, the belt guide pulley 90 is used as a drive pulley. When planting seedlings for bulbous vegetables using such a potato planting machine 10, normal seed potatoes 60 are prepared in a uniform size. For potatoes, etc., cut large ones and arrange them. And put the seed potato 60 from the input port 36 of the rake hopper 30,
The planting machine 10 is run by being pulled by a walking tractor. Then, the traction force rotates the wheel 14, and the torque of the wheel 14 becomes a driving force and is transmitted to the driven sprocket 92 via the rotating shaft 24, the sprocket 26, and the chain 28. Then, the power is further transmitted to a drive pulley 90 via a shaft 94 of the sprocket 92 and a bevel gear (not shown). Reference numeral 96 denotes a sprocket safety cover. The seed potato 60 drops from the main body 40 of the rake 30 into the rake cylinder 42, once rides on the transfer tool 44, is scooped up by the rising spoon 62, and vertically moves the inside of the hopper main body 40. Is transported in the upward direction. Then, it is conveyed in the lateral direction by the spoon belt 32 and is discharged when it reaches the end. However, the seed potato 60 is received by the delivery tool 78 installed at the upper end of the charging cylinder 34, and then falls on the back of the spoon 62 and falls inside the charging cylinder 34, and is discharged from the discharge port 72 by the cultivator 18. It is put into the formed groove. Then, since the soil can be covered with the disk 20, the planting is completed. The discharge port 7 of the charging cylinder 34
If 2 is arranged near the planting groove, the distance between the plants will be accurate because the falling distance from the discharge port 72 will be small. In this manner, when planting is performed while replenishing the seed potatoes 60 one after another, the seed potter delivery tools 44 and 78 are installed at locations where the seed potatoes 60 are likely to fit tightly in the supply path. The seedling 60 is not damaged due to the pinch, and the belt rotation of the planting machine 10 does not stop, and planting can be performed efficiently. As a delivery tool installed on the rake cylinder, a plastic resin plate or the like which has a high elasticity and protrudes so as to always close the inside thereof and which retreats when hit with a spoon may be used. A self-propelled type may be used instead of a type. According to the present invention described above, according to the first aspect of the present invention, the receiving portion for receiving the falling seeds is disposed slightly below the discharge port of the hopper body. After receiving the potatoes when they partially fall into the rake cylinder, the spoons are applied to retract the receiving portion, so that the seeds can be picked up smoothly. Therefore, the seeds are not pinched tightly inside the rake cylinder, the seeds are not damaged due to the pinching of the seeds, and the belt rotation accident of the planting machine does not occur, so that the planting can be performed efficiently. [0025] Since at least two bent rods having a seed pot receiving portion are used side by side in the seed pot delivering device, the soil or the like adhering to the seed potato easily falls through the gap, and the receiving portion receives Since it is hard to adhere, even when used for a long time, the transfer operation can be performed smoothly. Moreover, since the transfer tool is formed rotatably and the center of the transfer tool is inserted into the inside through the window opened in the rake cylinder wall, most of the transfer tool is externally exposed when the spoon hits it. , So that even if the rake cylinder is provided with a seed transfer device, it does not become an obstacle, and the scooping operation can be performed smoothly. According to the second aspect of the present invention, since the two seed transfer tools are arranged symmetrically inside the rake cylinder, the seed transfer means are both opened when the spoon hits, The scooping operation can be performed more smoothly.
