Hereinafter, the structure of the seeding apparatus 1 is demonstrated with reference to FIGS. The seeding apparatus 1 is connected to the rear of the traveling body 2 via the lifting link mechanism 20, and is a seeding machine for spraying a predetermined amount of seeds at a predetermined position while traveling by the traveling body 2.

The seeding apparatus 1 is equipped with the roll case 31 which accommodates each member for continuously conveying the seed supplied from the hopper 30 which stores a seed in predetermined amount continuously. The seeding apparatus 1 is equipped with six roll cases 31 side by side in the left-right direction so that 6 seed | pieces of seed may be sprayed simultaneously. The hopper 30 is configured to receive two trillion seeds, and the lower end is divided into two parts and connected to the roll case 31. That is, the seeding apparatus 1 is provided with three hoppers 30 side by side in the left-right direction. In the roll case 31, the feed roll 32 which is rotatably comprised, the groove 33 formed in the axial direction of the feed roll 32, and arranged in multiple numbers along the circumferential direction, and the upper direction of the feed roll 32 And a guide member 35 arranged near the surface of the conveying roll 32 to guide the seed retained in the groove 33 of the conveying roll 32 to the lower side of the conveying roll 32. ) Is provided.

The rice seed spreading sensor 36 is provided in the upper part of the roll case 31 and above the feed roll 32. The rice seed spreading sensor 36 has a function of alerting that the seed is less and the upper surface of the remaining amount is lower than that of the rice seed spreading sensor 36. However, by providing the rice seed spreading sensor 36 in the roll case 31, the hopper 30 is provided. ) And a decrease in seed amount in the roll case 31 when a bridge occurs at the connection portion between the roll case 31 and the roll case 31. Thereby, the formation at the time of seed blockage at the connection part from the hopper 30 can be prevented. The detection result by the rice seed spreading sensor 36 can be conveyed to the operator, for example by displaying it on the dashboard 14 of the driver's seat 11, or making a warning sound.

The roll case 31 is a lightweight case made of resin. The roll case 31 accommodates the seeds and houses the transfer roll 32, the partition brush 34, and the guide member 35 as a transfer unit for continuously transferring the seeds therein. The roll case 31 has an upper side connected to the hopper 30 and opens downward to face the ground.

The supply passage 40, which is a space for temporarily storing seeds supplied from the hopper 30, from the upper portion of the roll case 31, that is, from the connection portion with the upper hopper 30 to the feed roll 32, is provided. It is formed in the roll case 31. And the discharge passage 41 which becomes the discharge guide part of a seed is formed in the lower end of the supply passage 40 below the rotation axis of the feed roll 32, and the discharge port 42 is provided in the lower end side surface. The discharge passage 41 is provided to be inclined downward toward the discharge opening 42, and the discharge opening 42 is blocked by the cover 43. As mentioned above, the hopper part which accommodates a seed in the feed passage 40 and the discharge passage 41 of the hopper 30 and the roll case 31 is comprised.

The discharge passage 41 leading to the discharge port 42 is disposed on the side opposite to the side where the guide member 35 is disposed with the partition brush 34 interposed therebetween. That is, the discharge passage 41 is provided on the opposite side to the conveying direction of the conveying roll 32. In addition, the supply passage 40 is approximately half of the upper portion of the surface of the feed roll 32 (more specifically, in the outer circumference of the feed roll 32 until it reaches the partition brush 34 while being higher than the horizontal of the rotation shaft center). Part).

Thereby, seed does not leak to the guide member 35 at the time of discharge, and does not spill down under the roll case 31, and it can collect reliably. In the conventional structure, when discharging the residue in the hopper and the roll case, it was necessary to move or remove the partition brush or the guide member. And, in order to discharge the residue completely, it was necessary to remove or tilt the hopper itself.

The center of the horizontal direction of the supply passage 40 is provided so that it may be located outward rather than the outermost width of the feed roll 32. In other words, the center portion of the supply passage 40 is disposed below the upper end of the discharge passage 41 provided to contact the outer circumference of the feed roll 32. As a result, the center of the seed remaining in the supply passage 40 of the roll case 31 is positioned on the discharge passage 41 side, and when discharged through the discharge passage 41, discharge using the own weight of the seed is prevented. It is possible to improve the discharge rate.

FIG. Do.

Next, with reference to FIGS. 12-16, the structure of the guide member 35 is demonstrated.

The guide member 35 includes a main body 60 provided with a mounting portion to the roll case 31, an elastic body 61 disposed at a portion facing the groove 33 formed in the transfer roll 32, and an elastic body 61. A surface sheet 62 attached to the surface of) is provided.

The main body 60 has the depression 60a in the center part, and accommodates the elastic body 61 inside this depression 60a. The elastic body 61 is a member which consists of a material softer than a conveyed material, such as a sponge, for example, and has predetermined thickness. The elastic body 61 is attached to the bottom surface of the main body 60 depression 60a. The surface sheet 62 is a sheet member for reducing the friction coefficient of the surface of the guide member 35, and is provided over the entire surface of the elastic body 61 surface.

Thus, the elastic body 61 and the surface sheet 62 are attached with respect to the main body 60 fixed to the roll case 31. As shown in FIG. That is, the elastic body 61 and the surface sheet 62 are attached to the main body 60 so that replacement is easy.

As described above, even when the seed retained in the groove 33 receives an external force such as pressure from an adjacent seed by arranging the elastic body 61 in the portion facing the groove 33 of the guide member 35, The external force can be absorbed by the elastic force of the elastic body 61. Therefore, the seed can be protected by the elastic body 61 at the time of guidance by the guide member 35, and damage can be reduced. In particular, it is effective when conveying a conveyed object in which surface damage, such as a seed coated with the surface, becomes a problem.

FIG. 15 is a view showing a longitudinal cross section in a state where the elastic body 61 and the surface sheet 62 are attached to the main body 60. Both side portions 60b of the main body 60 of the guide member 35 are shown in FIG. It is provided so that the clearance with the surface of the feed roll 32 may become substantially zero. On the other hand, at the site where the depression 60a is formed in the main body 60, that is, the depression site in the main body 60 on which the elastic body 61 and the surface sheet 62 are mounted, the surface of the feed roll 32 is predetermined. It is arranged to leave a gap.

In this way, in the guide member 35, a predetermined gap is provided between the surface and the transfer roll 32 at a portion of the guide member 35 that faces the groove 33 of the transfer roll 32. Each gap is configured differently so that no gap occurs between the surface and the surface of the feed roll 32. As a result, the seeds held by the grooves 33 and the guide member 35 of the feed roll 32 do not overflow through the gap between the guide member 35 and the feed roll 32, so that the desired amount of seeds does not fall off. It can reliably feed continuously. In addition, since both parts 60b follow the feed roll 32 after assembling even if the position of both sides 60b is located inward of the outer periphery of the feed roll 32 in the state before parts are assembled, The clearance between the surface (surface sheet 62) of the guide member 35 and the feed roll 32 is ensured, and damage of the seed by pressurization from the guide member 35 can be prevented.

As shown in FIG. 16, the clearance of the surface of the guide member 35 (surface of the surface sheet 62) and the surface of the feed roll 32 exits compared with the clearance D1 of the entrance side to the guide member 35. As shown in FIG. The gap D2 on the side is set to be small, and at the same time, it is set to gradually decrease from the inlet side to the outlet side.

In this manner, when the gap D1 on the upper inlet side of the guide member 35 is made larger than the gap D2 on the lower outlet side, when the seed protruding from the groove 33 contacts the guide member 35. The possibility of damage can be reduced, and by narrowing the exit gap D2 of the guide member 35, it is possible to prevent the seed from overflowing from the gap between the guide member 35 and the feed roll 32.

In addition, the clearance gap D2 on the outlet side is set to half or less of the minimum width W1 of the seed which is a conveyed object. Thereby, it can reliably prevent seed from overflowing from the clearance gap between the guide member 35 and the feed roll 32. As shown in FIG. On the other hand, when making a conveyed thing into a rice seed, it is preferable to make the lower end (gap D2) of the clearance of the guide member 35 and the feed roll 32 into 2.0 mm or less.

On the other hand, in this embodiment, since the conveyed thing continuously conveyed by the conveying apparatus 1 was made into the oval-shaped seed, the minimum width W1 is made into the short axis diameter W1 of the ellipsoidal sphere. For example, in the case of a spherical conveyance, the minimum width W1 becomes a diameter.

Setting the gap with the surface of the feed roll 32 of the guide member 35 gradually changes the thickness of the depression 60a of the main body 60, for example, and makes the thickness of the elastic body 61 uniform. It is possible to put it. By making the thickness of the elastic body 61 uniform in this manner, there is an advantage that the effort at the time of disposing the elastic body 61 on the main body 60 can be reduced.

On the other hand, the present invention is not limited to these examples, and the thickness of the elastic body 61 is partially changed to finely adjust the elastic force along the circumferential direction of the roll, or a part or all of the elastic body 61 is intentionally contacted with the feed roll 32 to be spaced. You can think of adjusting the clearance.

In this embodiment, in order to protect the seed | seat held between the groove | channel 33 and the guide member 35, the elastic body 61 was arrange | positioned at the surface side of the guide member 35, As shown in FIG. You may arrange | position to the bottom face of 33, and the elastic body 61 may be arrange | positioned to both the guide member 35 and the groove | channel 33. When arrange | positioning at the bottom surface of the groove | channel 33, it can arrange | position similarly to the case where it arrange | positions to the depression 60a of the guide member 35, etc., and can arrange | position. By arrange | positioning the elastic body 61 in the bottom surface of the groove 33, it can prevent that a conveyed object is pushed toward the bottom surface of the groove 33, and damage to the surface of a conveyed object can be prevented.

Hereinafter, with reference to FIGS. 18-20, each embodiment which adjusts the working width of the division brush 34 according to the width | variety of the groove | channel 33 is demonstrated. That is, the following embodiment makes it possible to adjust the length of the brush part of the division brush 34 to the axial direction of the feed roll 32. As shown in FIG.

FIG. 18 divides the division brush 34 into a plurality of pieces in the width direction, arranges a plurality of division brushes 70 narrower than the division brush 34, and at a portion exceeding the width of the groove 33. The embodiment which provides the block 71 which fills the space instead of the divided division brush 34 is shown. The block 71 is a spill prevention part which prevents a seed from flowing out in the axial direction or the circumferential direction of the feed roll 32, and is arrange | positioned adjacent to the brush part of the division brush 70. As shown in FIG.

The block 71 is a substantially rectangular parallelepiped member having the same depth as the depth of the partition brush 34 (the length along the rotational direction of the transfer roll 32), and the surface and the transfer roll (on the transfer roll 32 side) 32) By using the smallest possible gap between the surfaces, it is possible to prevent the seed from overflowing toward the block 71.

In addition, the side of the block 71, which is a portion where the groove 33 does not exist, is tapered so that the side of the upstream side of the rotational direction upstream of the feed roll 32 of the block 71 faces the splitting brush 70. It is also possible to guide the seed which stays in the direction to the dividing brush 70, and to reduce the amount of retention.

FIG. 19 shows an embodiment in which a cover 72 covering the inlet side and the outlet side side surfaces of the partition brush 34 and the side surface of the groove 33 side is provided. The cover 72 is an outflow prevention part provided integrally with the brush part of the partition brush 34.

The cover 72 is a bending member formed by folding a flat plate twice outward in the same direction, and cuts 73 are provided at both ends thereof. On both sides of the base portion 34a of the partition brush 34, pins 34b corresponding to the incisions 73 are provided, and the incisions 73 of the cover 72 are attached to the pins 34b. In this way, the cover 72 is detachably attached to the partition brush 34.

As mentioned above, with the simple structure which attaches the cover 72 to the partition brush 34, the working width of the partition brush 34 can be adjusted.

In addition to the brush part 34, FIG. 20 implements the other division brushes 75 * 76 * 77 which differ in the width | variety in which a brush is formed, and selects the brush member which has the width | variety which matches the width of the groove | channel 33. It shows form. Also in this case, it is possible to reduce the seed which stays in front of the division brush 75 * 76 * 77 by extending the side surface of the conveyance roll 32 upstream in the taper shape. That is, it is also possible to integrally form the site | part adjacent to the site | part in which the brush part of each division brush 75 * 76 * 77 was formed as an outflow prevention part.

As mentioned above, the thing of optimal working width can be selected from a some brush member. In particular, it is effective when the width (desired feed amount) of the groove 33 is predetermined.

As described above, according to the embodiment shown in FIGS. 18 to 20, the working width of the partition brush 34 can be adjusted in accordance with the width of the groove 33. Therefore, the seed does not protrude from the groove 33 to the side in the width direction, and the rate at which the seed passes outside the width of the groove 33 is reduced, and it is ensured that the seeding is carried out a predetermined amount at a predetermined position. Moreover, it is also possible to reduce the damage of a seed by reducing the seed passing through the unexpected place.

21 and 22 show an embodiment in which the outflow prevention wall 78 is provided on each side of the upstream side and the downstream side in the rotational direction of the feed roll 32 of the partition brush 34. The outflow prevention wall 78 is a flat member provided along the circumferential direction of the feed roll 32, and the lower end is formed so that it may follow the outer peripheral surface of the feed roll 32. As shown in FIG. The outflow prevention wall 78 is arrange | positioned in the position (axial direction outer side of the conveyance roll 32) adjacent to the brush formation part of the compartment brush 34, and the seed is conveyed from the brush part of the compartment brush 34 ( 32) prevents leakage in the axial direction. The shape of the outflow prevention wall 78 is not limited to the said shape, What is necessary is just to prevent the outflow of the conveyed material of an axial direction.

As shown in FIG. 23, the partition brush 34 can also be arrange | positioned in the attitude | position that the hair tip was inclined toward the rotation direction upstream of the feed roll 32. As shown in FIG. For example, the partition brush 34 is disposed in a state of being inclined at about 5 ° from the rotation axis 50 of the feed roll 32, and the partition brush 34 as a whole is rotated as viewed from the rotation axis 50 of the feed roll 32. It is arranged inclined downstream in the direction. That is, the tip of the bristles of the division brush 34 is provided so that it may be located in the rotation direction upstream of the feed roll 32 rather than a root.

By such a structure, the hair tip of the partition brush 34 is bent in a substantially vertical direction by receiving pressure from the seed, and it becomes easy to block the seed which protruded from the groove 33. In other words, the seeds projecting upward of the groove 33 can be reliably partitioned by contacting the seed brush and the partition brush 34 so that the seeds continuously conveyed from the hair end of the partition brush 34 face to face.

Moreover, as shown in FIG. 23, the partition brush 34 is located in the rotation direction upstream rather than the vertex of the up-down direction of the feed roll 32. As shown in FIG. Thus, the seed which stays in the upper part with respect to the seed which overflowed from the groove 33 when passing through the partition brush 34 by arrange | positioning the partition brush 34 below the upper part of the feed roll 32 directly. Downward pressure is applied. Thus, by naturally acting as a brake when the seed outside the groove 33 passes through the partition brush 34, the probability of the seed protruding from the groove 33 invading into the partition brush 34 can be lowered. .
