Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. Fig. 1 shows a state in which the working machine of the present invention is mounted on the rear surface of the tractor T. Fig. The working machine in the present invention includes a point spread seeder (100). In addition to the point spreader 100, the rotary 110 and the fertilizer spreader 120 may also be included.

The rotary 110, the fertilizer spreader 120 and the point spreading planter 100 are supported by the main frame F at the rear of the tractor T. It is widely used to attach a work machine such as a rotary 110 and a fertilizer spreader 120 by using a main frame F mounted on the rear of a current tractor T. [ It is widely used that the main frame F is connected to the rear of the tractor T in a three-point supporting manner. For example, the main frame F is supported by using one upper link 122 and a pair of lower links 124 on both sides of the lower portion of the upper link.

In the present invention, the main frame (F) is defined as an entire body made of a plurality of metal links (for example, a rectangular cross-section link or a circular cross-section link) so as to support various working machines . That is, all of the working devices, including the rotary 110, the fertilizer spreader 120, and the point spreading planter 100 to be described later, are substantially supported by the main frame F. [

The rotary 110 is widely used and performs a rotary operation and is supported by the main frame F. [ And the supporting structure of the rotary itself are substantially known, and a detailed description thereof will be omitted. According to the present invention, the fertilizer spreader 120 is installed in the main frame F. Although the installation position of the fertilizer spreader 120 is not limited, it is preferable that the feed pipe 126 (see FIG. 2) in which fertilizer is sprayed at least by the fertilizer spreader 120 is installed in front of the rotary 110 described above.

Referring to FIG. 2, an exemplary configuration of the fertilizer spreader 120 will be described. The fertilizer spreader 120 includes a loading box 122 containing fertilizer, a feed pipe 126 connected to the inside of the loading compartment and supplying fertilizer, and a fertilizer spreader 120 connected to the main frame F And a fertilizer spreader frame 124 supporting the fertilizer spreader frame. At the lower end of the fertilizer spreader frame 124, a support shaft 128S for supporting a pair of wheels 128 is rotatably installed. A driving sprocket Sa is provided on the support shaft 128S and a driven sprocket Sb is provided on a shaft Sc connected to the stirring device in the loading box.

A chain (C) is provided between the drive scraper and the driven sprocket. As the wheel 128 rotates in contact with the ground surface, the rotational force of the chain C is transmitted to the shaft Sc, and the fertilizer in the loading box is dropped downward through the supply pipe 126. The fertilizer spreader 120 may be an example, and the fertilizer spreader 120 of another configuration may be installed in the main frame F as long as it is capable of spreading the fertilizer like traveling.

At the rear of the rotary 110, a lath molding machine 170 is supported on the main frame F. [ The ladder molding machine 170 may be detachably mounted on the frame F as other components such as the fertilizer spreader 120, the vinyl holder 132, and the like. The ladder forming machine 170 forms a ladder of a certain height on a cultivation land which has been completed by the rotary 110 by a rotary operation.

10, the ladder molding machine 170 is composed of a pair of left and right side walls 172 and a rear wall 174 provided between the rear ends of the side walls 172. As shown in FIG. The pair of sidewalls 172 have a width corresponding to the width of the bank, and extend in the front and rear directions to be substantially opposed to each other. The sidewall 172 has a function of collecting the soil that has been subjected to the rotary work at a certain height from both sides so that the planting area where the rotary work is completed has a certain width (interval of the pair of side walls).

The rear wall 174 provided at the rear end of the pair of side walls 172 is formed to be higher than the side wall 172 so that the lower end of the rear wall 174 determines the height of the floor. That is, in the ladder molding machine 170, the soil is gathered by the pair of side walls 172 so as to correspond to the width of the ladder, and the gathered soil is leveled by the lower end of the rear wall 174 to have a constant height.

Such a ladder molding machine 170 itself can be said to be practically known. For reference, the rotary 110 described above is installed such that the screw-type blades for rotary work are symmetrical so that the rotary work can be gathered in the center portion of the soil. After the work is completed by the rotary 110, a tile having a predetermined height is formed by the slitting machine 170 described above. In the present specification, the term "cultivation area" means a layer having a certain width and height.

A vinyl stand 132 for supporting a roll-shaped vinyl 130 is supported by the main frame F at the rear of the rotary 110 and the ladder molding machine 170. The vinyl holder 132 supports the central space portion of the vinyl roll 130 wound in a roll shape on both sides. The vinyl roll 130 supported by both end portions of the vinyl holder 132 can release the vinyl wrapped around the rotating roll 130. This vinyl roll 130 can be regarded as a vinyl wrapped around a peat sown with peanuts. At first, a user pulls an end of a vinyl and connects it to the ground. Then, the vinyl roll 130 is loosened according to the running of the tractor T, The upper part of the lattice is wrapped in the upper part.

At the rear of the vinyl stand 132, a vinyl press roller 140 for pressing the vinyl is provided on the pair of right and left main frames F. The vinyl pushing roller 140 is provided for pressing a vinyl covering the upper surface of the bed by being loosened by the vinyl stand 132. The pair of vinyl pushing rollers 140 has a width smaller than the left and right width of the vinyl. In addition, a pair of dunnage covers 150 are supported on the main frame F immediately after the vinyl press roller 140. The gypsum lid 150 covers both sides of the vinyl by covering both sides of the upper surface of the vinyl press roller 140 that rotates while contacting the ground.

FIG. 3 exemplarily shows that the vinyl press roller 140 and the mud cover 150 cover the vinyl V. FIG. 3, the duckbill cover 150 is formed in the form of a plate-like roller. The pair of duckbane covers 150 have a narrow bottom surface when seen from the front or rear side, And is provided so as to be inclined and facing so as to have a narrow width on the rear side and a wide front side when viewed from the upper side. Accordingly, with respect to the peanut planted on the bank between the corrugations of the plantation land, the vinyl (V) loosened from the vanill roll 132 described above covers the bank, and the soil is covered with the vinyl (V). It can be seen that the pair of the dunn lids 150 and the vinyl press rollers 140 are formed into a pair having a predetermined interval and rotated while contacting the ground surface as the tractor T is running.

Next, a point spreading planter constituting a main part of the working machine of the present invention will be described with reference to FIG. The point spreading planter 100 is connected to and supported by the main frame F described above by the seeder frame 160. In the illustrated embodiment, the seeder frame 160, which connects and supports the point spreading planter 100 to the main frame F, is illustratively formed at a right angle when viewed from the side, (100) to the main frame (F).

The seeder frame 160 is connected to an auxiliary frame 15 supported by the seeder 100. An outer end 162 of the seeder frame 160 is connected to the auxiliary frame 15, for example. It is natural that the connection between the seeder frame 160 and the auxiliary frame 15 can be connected by welding or structurally connected to each other. The auxiliary frame 15 is configured to support substantially the whole of the point spread type seeder 100 on the seeder frame 160. The auxiliary frame 15 is supported on the support shaft C for supporting the rotating body 20, So as to support the point spread planter 100.

The above-described point spreading planter 100 includes a rotating body 20 that rotates while contacting with the ground during driving of a tractor or the like. The rotating body 20 is formed in a cylindrical shape having a predetermined thickness, and a plurality of seeding hoppers 40 are provided on the outer side thereof. The rotating body 20 is connected to a supply hopper 10 installed at an upper portion through a connecting pipe 12. Therefore, seeds (for example, peanuts) put in the supply hopper 10 are supplied to the inside of the rotating body 20 through the connecting pipe 12. The seed supplied to the inside of the rotating body 20 is discharged through the seeding hopper 40 installed on the outer side of the rotating body 20, and then seeded on the branch of the planting land.

FIG. 5 is an exploded perspective view of a point spreading planter, which is one of the working machines according to the present invention. FIG. 5A is an exploded perspective view from the left side, and FIG. 5B is an exploded perspective view from the right side. Referring to FIGS. 5A and 5B, the connection pipe 12 is provided so as to communicate with the supply hole 14c of the support member 14. As shown in FIG. The support member 14 is formed in a disc shape having a predetermined thickness and includes a side surface portion 14b on a circular plate on which the supply hole 14c is formed and a circumferential surface 14a surrounding the circumferential portion of the side surface portion 14b . The circumferential surface 14a is formed with a cutout portion 14d, which is partially opened. The cut-out portion 14d is a portion for feeding the seed to the seeding hopper 40 of the rotating body located outside the seed.

The support member 14 is connected to the supply pipe 12 and is actually supported in a fixed state as described later. A fixing member 50 is fixed to the inner surface of the support member 14. [ The fixing member 50 includes a side wall 56 partially formed in an arc shape, a circumferential surface 52 forming a circumferential surface of the side wall 56, and a plate-shaped protrusion 52 extending outward from the circumferential surface 52. [ (54). The circumferential surface 52 is coupled in the form of closing the through hole of the seed mold 60 to be described later, and connects between the highest point and the lowest point.

5, the circumferential surface 52 of the fixing member 50 is fixed at a position including a position corresponding to the cut-out portion 14d of the support member 14 described above . The protruding portion 54 of the fixing member 50 protrudes outward from the circumferential surface 52 at a position corresponding to the lowest point of the cutout portion 14d with reference to the rotating direction of the rotating body 20. [ The support member 14 and the fixing member 50 described above are held in a fixed state without rotating substantially.

The members described below are substantially rotatable. Hereinafter, a rotating component will be described with respect to the fixed support member 14 and the fixing member 50. The rotating body 20 described above includes a circular support plate 22 and a circumferential surface 24 which forms the circumferential surface of the support plate 22. [ The plurality of seeding hoppers 40 are provided on the circumferential surface 24 as described above. The bracket portion 23 bent inwardly from the circumferential surface 24 is a portion to be engaged with the ring-shaped outer cover 16.

A plurality of guide members 26 corresponding to the seeding hoppers 40 are mounted in the rotating body 20 at portions corresponding to the seeding hoppers 40. The guide member 26 has a wide inlet 26a and a narrow outlet 26b so that the seed supplied from the inside can be guided safely into the seeding hopper 40 through the narrow outlet 26b .

The seed frame 60 is fixed to the inside of the rotating body 20 just inside the guide member 26 so as to rotate as the rotating body 20. The seed frame 60 may be said to be provided between the fixing member 50 and the support member 14 in the interior of the rotating body 20. [ 5 (a) shows the seed mold 60 itself, and Fig. 5 (b) shows an example in which the fixing member 50 is coupled to the inner surface of the seed mold 60. Fig.

As shown in the figure, the seed mold 60 is formed in a ring shape having a constant width and thickness, and a through hole 62 through which the seed passes is formed in the circumferential portion 64 so as to penetrate the inside and the outside of the seed mold 60 . A connection groove 66 having a width smaller than that of the through hole 62 is formed on the inner surface of the circumferential portion 64 to connect the through hole 62 with each other.

The connection groove 66 is a space into which the protrusion 54 of the fixing member 50 can enter. That is, the projecting portion 54 is inserted into the connection groove 66 of the rotating seed frame 60 and rotated to pull the peanut remaining in the storage groove 68 to the middle portion of the seed frame. It is normal that the peanut in the receiving groove 68 falls down by its own weight and reaches the seeding hopper 40 through the passing hole 62 before reaching the bottom dead center in the process of rotating the seed frame 60. However, if the peanut does not fall into its own weight due to entering into the receiving groove 68 or the like, the peanut in the receiving groove 68 must be removed because the peanut can not be stored in the next rotation. For this, a protrusion 54 is formed on the outer surface of the circumferential surface 52 of the fixing member 50 so that the protrusion 54 is formed in the receiving groove 68 along the connecting groove 66 in accordance with the rotation of the seed mold 60 The peanut is drawn to the through hole 62 side.

It is preferable that the width of the through hole 62 is substantially determined in consideration of the size of the seed. For example, when used as a peanut seeder, the width of the through hole 62 is set so that one peanut can pass through Or more. The length of the through hole 62 in the circumferential direction is set such that the peanut contained in the through hole 62 rotates outward through the through hole 62 and enters the outside seeding hopper 40 through the guide member 26 To a predetermined length. As shown in Fig. 6, a receiving groove 68 into which seeds are inserted is formed on one side of the passage hole 62 (on the downstream side of the passage hole with respect to the rotating direction). The receiving groove 68 may be formed as a portion communicating with the through hole 62. When the peanut is taken out from the receiving groove 68, the receiving groove 68 may be passed through the through hole 62 to the outside.

The receiving groove 68 is for allowing a peanut having a certain level to enter into the seed frame 60 in accordance with the rotation of the seed frame 60. Therefore, the peanut that has entered the receiving groove 68 through the passing hole while the seed frame 68 is rotated does not fall downward even if the corresponding passing hole 62 rotates and is located at the uppermost position. When the seed mold 60 further rotates and is positioned at approximately 9 o'clock (substantially, the storing groove is positioned substantially perpendicular to the through-hole), the peanut in the inside of the storing groove 68, (68) to the through hole (62).

The through hole 62 is in a state in which it is not in communication with the outer side by the circumferential surface 14a of the support member 14 provided on the outer side of the support member 14 and only in the cutout portion 14d of the support member 14, Can communicate with each other. The passage hole 62 is also blocked by the circumferential surface 52 of the fixing member 50 from the uppermost portion (referring to the direction descending from the uppermost portion in the rotational direction) to the position corresponding to the cutout portion 14d have.

When the seed mold 60 rotates and reaches the position corresponding to the cutout 14d of the fixing member 14, the through hole 62 is in the open state, so that the peanut contained therein passes The inner side of the through hole 62 is blocked by the circumferential surface 52 of the fixing member 50 at this time. Therefore, peanuts (due to the free fall of the peanut 60 from the through hole 62 in the receiving groove 68 because the receiving groove 68 is located above the through hole 62) And is supplied to the outside through the cutout portion 14d. Thus, the peanut dropped through the cut-out portion 14d is guided by the guide member 26 into the inside of the seeding hopper 40.

Here, the pair of the through-holes 62 are formed to control the number of peanuts in one seeding. That is, the inside width of the through-hole 62 is formed to have a size that allows one peanut to be inserted, and the depth of the receiving groove 68 is set so that one or two peanuts can be inserted . Therefore, when the through hole 62 and the receiving groove 68 are formed into a pair, it can be seen that two to four peanuts can be sown through the receiving groove 68 at a time of sowing.

The rotary frame 20 and the seed frame 60 coupled to the inside of one side of the rotary body 20 rotate about the support shaft C as described above. The support shaft C is formed at the center of the center hole 21 formed at the center of the support plate 22 on the disk of the rotator 20 and the side plate 65 of the seed frame 60 And is rotatably supported through the center hole 65a. The center hole 21 of the rotating body 20 may be formed inside the boss 21a coupled to the center of the support plate 22 so as to secure a stronger supporting force than that of the rotation of the rotating body .

It can be seen that the support shaft C described above substantially supports the above-mentioned rotating component at its center. It is a matter of course that at least one end of the supporting shaft C should be supported by the above-described auxiliary frame 15. [ Therefore, as shown in FIG. 5B, at least one end portion of the support shaft C is supported by the support portion 15a formed on the auxiliary frame 15. As shown in FIG. The auxiliary frame 15 can be constructed so as to support both ends of the support shaft C by a person of ordinary skill in the art.

Next, the configuration of the seeding hopper 40 provided on the circumferential surface 24 of the rotating body 20 will be described. The seeding hopper 40 has a function of receiving the seed (peanut) supplied from the inside and planting it on the ground as described above. For seeding of such seeds, the seeding hopper 40 is preferably formed so that it can be opened and closed, and its end portion is formed to have a sharp shape. It can be seen that the seeding hopper 40 in the illustrated embodiment is formed into a conical shape having a conical shape or a convex intermediate portion.

7 and 8, the seeding hopper 40 includes a body 42 capable of receiving seed therein and a cover 44 for opening and closing the body 42 . The cover 44 is rotatably supported at one side of the upper surface of the body 42, and is rotatably supported about a support shaft 44a, for example.

An upper end 44b of the cover 44 extending to the upper portion of the support shaft 44a is connected to the first lever 47 in a pin connection manner. The other end of the first lever 47 is connected to the second lever 48 and the middle portion of the second lever 48 is rotatably supported on the back surface of the support plate 22. For example, the second lever 48 is rotatably supported on the support plate 22 about the support shaft 48a, and the second lever 48 is urged by the spring 49 so as to be pulled to one side. .

The spring 49 pulls the second lever 48 in a direction substantially closing the cover 44. [ The opening and closing protrusion 41 is connected to the outer end of the supporting shaft C while the opening and closing protrusion 41 is connected to the rotating body 20 in a fixed state. As a matter of course, the opening / closing protrusion 41 may be supported by other components as long as the opening / closing protrusion 41 can maintain the fixed position. It may be formed in a fixed portion for supporting the support shaft C inside the frame F, for example, in order to support the outer end of the support shaft C. [ The opening and closing projections 41 are substantially fixed at a position just before the seeding hopper 40 reaches the bottom dead center.

8, the opening / closing protrusion 41 maintains the predetermined position, and the second lever 48 rotates like the rotating body 20. Immediately before the seeding hopper 40 reaches the bottom dead center, the inner end of the second lever 48 is brought into contact with the opening / closing projection 41. The second lever 48 is rotated in the clockwise direction about the support shaft 48a so that the second lever 47 pulls the upper end 44b of the cover 44 to open the cover 44 Which is shown by arrows in Fig.

Since the opening and closing projection 41 has a circular arc shape at a certain angle, the cover 44 is kept open while the second lever 48 is rotated while contacting the opening and closing projection 41. Here, when the rotating body 20 rotates further, the cover 44 is closed by the elastic force of the spring 49. The opening and closing mechanism of the seeding hopper as described above is provided on the other side of the support plate 22 of the rotating body 20 and the outer side surface thereof is closed by the cover 18. [

Therefore, when the rotator 20 rotates and the seeding hopper 40 reaches the bottom dead center, the cover 44 is opened, so that the peanut therein can fall down. At this time, since the seeding hopper 40 is slightly digging into the ground of the cultivation land, it can be understood that the seed is sown at the depth of the required depth.

Next, another embodiment of the seeder of the present invention will be described with reference to FIG. The present embodiment is an embodiment further including a soil covering mechanism for covering the soil on the seed after the seed is sown on the field by the point spreading seeder 100 having the above-described structure. As shown in the drawing, a submerged frame 72 is installed on the subframe 15, and an elastic lever 74 is rotatably connected to the submerged frame 72 around the fulcrum a . A putting roller 70 is rotatably mounted on the lower end of the elastic lever 74.

The ground roller 70 rotates in contact with the ground surface and functions to cover the concave portion generated in the seeding process of the peanut with soil. The resilient lever 74 is resiliently supported by a spring 76 so as to be directed forward, and an arc-shaped slot 78 formed at the upper end of the resilient lever 74 is engaged with the resilient lever 74, And the projection (b) is engaged. 9, the covering roller 70 is elastically supported forward by the spring 76, and can be moved backward for a certain period by the slot 78 and the projection b . It can be seen that by passing the upper part of the recessed part sown in this state, covering the soil around the concave part with the part again, the sowing seed can be buried with the soil. As such, by utilizing the elastic force of the spring 76, it is natural that the seeding of seeds seeded will proceed more efficiently. That is, since the grass cover roller 70 is pulled forward by the elastic force, the surrounding soil can be covered more efficiently.

Hereinafter, the overall operation of the point spreading planter of the present invention having the above-described configuration will be described. Referring to FIG. 4, the feed hopper 10 contains seeds, for example, peanuts at a certain level, and these peanuts are introduced into the interior of the rotating body 20 through the supply pipe 12. Here, the lower end of the supply pipe 12 is connected to a position slightly lower than the middle of the support member 14. Accordingly, the peanuts supplied to the interior of the rotating body 20 maintain a certain level, which is maintained to a level corresponding to the height of the supply pipe 12.

Following the rotary operation by the rotary 110, the vinyl V is loosened by the vinyl roll 130 supported by the vinyl holder 132 and traveled while contacting the ground. Subsequently, both ends of the vinyl (V) are pressed by the pair of vinyl press rollers 140, and the pair of dirt cover 150 collects and covers the both sides of the vinyl V, and work proceeds. Here, the fertilizer supplied to the ground by the fertilizer spreader 120 is performed before the operation of the rotary 110, thereby enabling efficient application of the fertilizer.

The peanuts supplied to the inside of the rotating body 20 are accumulated in the seed mold 60 shown in Figs. 6 and 7. More specifically, in the space corresponding to the inside of the seed mold 60, peanuts are piled up in a space which is clogged by the support member 14. [ In accordance with the traveling of the tractor, the rotating body 10 of the point spreading seeder of the present invention rotates while contacting the ground surface of the plantation ground.

The seed frame 60 also rotates in accordance with the rotation of the rotating body 20 in the counterclockwise direction. At this time, the seed frame 60 is rotated in the reciprocating groove 68 connected to the through hole 62 formed in the inner side of the seed frame 60 There are about two peanuts (see Figure 7). Here, among the inner surfaces of the seed mold 60, the rotating body is blocked by the circumferential surface 52 of the fixing member 50 in the section where the rotating body comes down from the apex (peak) And the peanut can be inserted into the receiving portion 68 through the through hole in a region where the seed mold 60 is lifted.

Then, the peanut in the inside of the receiving groove 68 rotates further at the position of about 9 o'clock (further, the receiving groove is located substantially in the vertical direction with the passing hole) The seed mold 60 comes to a position corresponding to the cut portion 14d of the fixing member 14 while the seed mold 60 rotates. Therefore, since the through-hole 62 is in the open state, the peanut contained in the through hole 62 falls outside through the through hole 62. That is, the peanut that has passed through the through hole 62 in the receiving groove 68 is supplied to the outside through the cutout portion 14d. In this way, the peanut dropped through the cutout 14d is guided by the guide member 26 and enters the inside of the seeding hopper 40. This is a state substantially before the seeding hopper 40 is positioned at the bottom dead center.

Immediately before the seedling hopper 40 reaches the bottom dead center while the rotating body 20 rotates, the cover 44 of the seeding hopper 40 is opened by the body 42 and the peanut inside the seeding hopper is discharged to the outside do. Since the cover 44 is opened in the body 42 as described above, detailed description is omitted. In this state, the seeding hopper 40 is positioned substantially at the bottom dead center, and it can be said that the seeding hopper 40 has entered the ground at a predetermined depth. In this state the cover is opened and the inner peanut is seeded in the ground. This seeding will be repeatedly performed in accordance with the rotation of the rotating body 20, and the seeding interval will be determined according to the size of the rotating body. When the seeding is completed in this way, the grass rollers 70 disposed behind the grass cover roller 70 cover the surrounding soil generated during sowing, passing through the sown seedling, thereby completing sowing.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It should be interpreted.
