Detailed Implementation

[0028] Hereinafter, embodiments of the work vehicle disclosed in this application will be described in detail with reference to the accompanying drawings. Furthermore, the present invention is not limited to the embodiments shown below. Hereinafter, a seedling transplanter for planting seedlings in farmland will be described as an example of the work vehicle.

[0029] Furthermore, in the following explanation, the forward and backward direction refers to the direction of travel of the seedling transplanter when it is moving in a straight line. The front side of the direction of travel is defined as "front," and the rear side is defined as "rear." The direction of travel of the seedling transplanter refers to the direction from the operator's seat towards the steering wheel when it is moving in a straight line.

[0030] The left and right directions are horizontally orthogonal to the front and back directions, with the left and right sides fixed towards the "front". That is, when the operator (also known as the worker) is seated facing forward, the left side is "left" and the right side is "right".

[0031] The vertical direction refers to the vertical direction. The front-back, left-right, and vertical directions are orthogonal to each other. These directions are defined for ease of explanation and are not limited to this invention.

[0032] Reference Figure 1 and Figure 2 The seedling transplanter 1 of the implementation method will be described. Figure 1 This is a side view of the seedling transplanter 1 according to the embodiment. Figure 2 This is a top view of a portion of the seedling transplanter 1, omitting the embodiment. The seedling transplanter 1 has a seedling planting section 4 mounted flexibly at the rear of the vehicle body 2 via a lifting linkage mechanism 3. The main body of a fertilization device 5 is located on the upper rear side of the vehicle body 2.

[0033] The vehicle body 2 is a four-wheel drive vehicle equipped with a pair of front wheels 10 on the left and right sides and a pair of rear wheels 11 on the left and right sides as drive wheels. An engine is mounted on the main frame 12 of the vehicle body 2. The rotation generated by the engine is a hydrostatic continuously variable transmission called HST. The rotational power generated by the rotational change is separated into driving power and external extraction power and extracted. The driving power is transmitted to the front wheels 10 and the rear wheels 11. The external extraction power is transmitted to the seedling planting section 4 and to the fertilization device 5.

[0034] The engine is housed in an engine hood 15. A control seat is located on the upper part of the engine hood 15. A front cover 17 with various operating mechanisms is located in front of the control seat. A pair of seedling racks 20 for resupplying seedlings are located on the left and right sides of the front cover 17. A steering wheel 21 for operating the front wheels 10 is located on the upper part of the front cover 17.

[0035] The lower left and right sides of the engine hood 15 and front cover 17 are provided with horizontal bottom pedals 25. Part of the bottom pedals 25 is grid-shaped, for example, to allow mud or other debris adhering to the operator's shoes to fall onto the farmland. At both ends of the bottom pedals 25, there are auxiliary pedals 27 that are set lower than the upper surface of the bottom pedals 25. The auxiliary pedals 27 make it easier for the operator to get on and off the seedling transplanter 1.

[0036] The lifting linkage mechanism 3 is a parallel linkage mechanism, comprising an upper linkage 30 and a lower linkage 31. The front ends of the upper linkage 30 and the lower linkage 31 are rotatably supported in the up-and-down direction on a rear-mounted, portal-shaped linkage base 32, which is erected at the rear end of the main frame 12. Furthermore, a longitudinal linkage 33 is connected to the rear ends of the upper linkage 30 and the lower linkage 31. A connecting shaft 34, rotatably supported on the seedling planting section 4 and extending along the front-and-rear direction of the vehicle body 2, is connected to the lower end of the longitudinal linkage 33. The seedling planting section 4 is rotatably positioned around the connecting shaft 34.

[0037] The seedling planting section 4 includes a seedling placement section 40 and a seedling planting device 41. The seedling placement section 40 places pad-shaped seedlings and supplies seedlings one by one to the seedling outlets of each row in a left-right direction. When a row of seedlings is supplied to the seedling outlets, the seedlings are moved downward by the seedling conveyor belt 40a.

[0038] The seedling planting device 41 removes the seedling from the seedling placement section 40 by rotating the seedling planting component and plants the seedling in the farmland.

[0039] At the lower part of the seedling planting section 4, a central floating body 45 is provided in the center, and side floating bodies 46 are provided at both ends. When the machine body moves with the central floating body 45 and side floating bodies 46 positioned on the mud surface of the farmland, the central floating body 45 and side floating bodies 46 slide on the mud surface while leveling it. The seedling is planted onto the leveled farmland surface by the seedling planting device 41. In addition, the central floating body 45 and side floating bodies 46 are configured to move up and down in accordance with the unevenness of the surface soil of the farmland, for example, by rotating freely around a support axis in the left and right direction.

[0040] The fertilization device 5 includes a fertilizer hopper 50, a delivery mechanism 51, and a blower 52. The fertilization device 5 uses air blown by the blower 52 to transport fertilizer released from the fertilizer hopper 50 by the delivery mechanism 51, and supplies fertilizer to the farmland through the fertilization pipe 53 and the like.

[0041] A pair of fertilizer hoppers 50 are provided on the left and right sides of the vehicle body 2. Specifically, the fertilizer hoppers 50 are respectively located at the left and right ends of the vehicle body 2. The fertilizer hoppers 50 store fertilizer supplied to the farmland.

[0042] The fertilizer hopper 50 branches into four chambers along the front-to-back direction on its lower side. Each chamber has an opening at its bottom. A pair of fertilizer hoppers 50 are arranged on the left and right sides, with four openings on the lower side. The number of openings on the lower side depends on the number of rows in the seedling transplanter 1. In this embodiment, the seedling transplanter 1 has an 8-row structure, with eight openings formed in a pair of fertilizer hoppers 50. Alternatively, the fertilizer hopper 50 can be configured to be divided into four chambers. A feeding mechanism 51 is connected to each opening on the lower side.

[0043] The fertilizer hopper 50 has an opening at the top, allowing fertilizer to be fed in from above. An openable and closable cover 50a is installed at the top of the fertilizer hopper 50.

[0044] The cover portion 50a rotates around a rotating shaft located on the outer side of the fertilizer hopper 50. Specifically, the cover portion 50a rotates around a rotating shaft located on the outer side of the fertilizer hopper 50 in the left-right direction.

[0045] The feeding mechanism 51 rotates the feeding section to transport the fertilizer in the fertilizer hopper 50 to the fertilizer pipe 53 located below. A recess is formed in the feeding section, and as it rotates, the fertilizer flowing into the recess is transported to the fertilizer pipe 53.

[0046] Blower 52 blows air into each fertilizer pipe 53. The air blown into the fertilizer pipe 53 pushes the fertilizer in the fertilizer pipe 53 into the farmland. Thus, fertilizer is supplied to the farmland. The fertilizer pipe 53 is configured to supply fertilizer to the front side of the seedling planting device 41.

[0047] The seedling transplanter 1 of this embodiment includes a mounting platform 60 that can be disposed above the fertilizer hopper 50. Next, referring to... Figures 3-5 The mounting platform 60 will be described below. Figure 3 This is a top view of the area near the fertilization device 5 in the embodiment. Figure 4 This is a side view of the fertilizer application device 5 in the embodiment. Figure 5 This is a rear view of the vicinity of the fertilization device 5 in the implementation method, viewed from the rear. Figures 3-5 This indicates the vicinity of fertilizer application device 5 located on the left.

[0048] The loading platform 60 can hold fertilizer, seedlings, and other work materials. The loading platform 60 can be switched between a loading position and a storage position via a switching mechanism 61. The loading position is located above the fertilizer hopper 50, where work materials can be placed. The storage position is located away from the fertilizer hopper 50, where the loading platform 60 is tucked away and work materials cannot be placed. For example, the storage position is located in the left-right direction, further inward than the fertilizer hopper 50. Specifically, the storage position is located facing the side wall of the fertilizer hopper 50 in the left-right direction, and the loading platform 60 is approximately parallel to the vertical direction. Figure 5 The table 60, which has both a placement position and a storage position, is shown in the diagram.

[0049] The loading platform 60 is shaped to be approximately the same size as the opening of the fertilizer hopper 50 when viewed from above. The loading platform 60 is plate-shaped and has multiple holes 60a. For example, the holes 60a are arranged in three rows along the front-to-back direction and three rows along the left-to-right direction. A stopper 60b is formed at the end of the loading platform 60 to prevent the falling of work materials. The loading platform 60 rotates about a rotation axis located on the outer side of the fertilizer hopper 50. For example, the loading platform 60 rotates about a rotation axis located on the inner side of the fertilizer hopper 50. The loading platform 60 also rotates in the left-to-right direction about a rotation axis located on the inner side of the rotation axis of the cover portion 50a.

[0050] The loading platform 60 rotates in a direction different from the rotation direction of the cover 50a of the fertilizer hopper 50. Specifically, the cover 50a rotates around a rotation axis that is located on the outer side of the fertilizer hopper 50 in the left-right direction, while the loading platform 60 rotates around a rotation axis that is located on the inner side of the fertilizer hopper 50 in the left-right direction. That is, the loading platform 60 and the cover 50a rotate relative to the fertilizer hopper 50 around rotation axes located in different directions.

[0051] The switching mechanism 61 includes a support frame 62, a support arm 63, and a connecting portion 64. The support frame 62 is, for example, a metal tube. The support frame 62 is generally U-shaped. The support frame 62 includes: a first component 62a for mounting a platform 60; a second component 62b extending downward from one end of the first component 62a; and a third component 62c extending downward from the other end of the first component 62a.

[0052] The first component 62a is configured to extend in the front-to-back direction. The first component 62a is located laterally inside the fertilizer hopper 50 in the left-to-right direction. The first component 62a is located above the fertilizer hopper 50. Specifically, the first component 62a is located above the rotation axis of the cover 50a of the fertilizer hopper 50. A gap is provided between the platform 60 and the first component 62a to allow an operator to insert their hand.

[0053] The second component 62b extends downward from the front end of the first component 62a. The second component 62b is located forward of the fertilizer hopper 50. A handrail 62d is provided on the second component 62b. The handrail 62d is held by the operator when ascending or descending.

[0054] The third component 62c extends downward from the rear end of the first component 62a. The third component 62c is located further rearward than the fertilizer hopper 50.

[0055] The second component 62b and the third component 62c are formed such that the upper end side bends inward in the left-right direction.

[0056] The support arm 63 is configured to extend in the left-right direction. Two support arms 63 are arranged side by side in the front-back direction. The support arm 63 is rotatably mounted to the first component 62a of the support frame 62 via the connecting part 64. A platform 60 is mounted on the support arm 63. That is, the platform 60 is rotatably mounted to the first component 62a of the support frame 62 via the support arm 63 and the connecting part 64.

[0057] The support arm 63 is generally L-shaped. A hole is formed at the base end 63a of the support arm 63. The rotating shaft 65 is inserted into the hole in the front-to-back direction.

[0058] When the platform 60 rotates, the base end 63a of the support arm 63 abuts against the first member 62a, holding the platform 60 in the placement or storage position. That is, the base end 63a of the support arm 63 also functions as a stopper that restricts the rotation of the platform 60 to the placement or storage position. Specifically, when the platform 60 is in the storage position, one side 63b of the base end 63a of the support arm 63 abuts against the first member 62a. Furthermore, when the platform 60 is in the placement position, the other side 63c of the base end 63a of the support arm 63, opposite to one side 63b, abuts against the first member 62a.

[0059] A connecting portion 64 is mounted on the first component 62a. The connecting portion 64 rotatably supports the support arm 63. The connecting portion 64 is configured to protrude upward from the first component 62a. A hole is formed in the connecting portion 64. A rotating shaft portion 65 is inserted into the hole in a front-rear direction. The rotating shaft portion 65 has a head 65a at one end that abuts against the connecting portion 64, and a hole 65b is formed at the other end for inserting a pin to prevent it from falling off.

[0060] Next, the function of the mounting stage 60 will be explained.

[0061] The platform 60 can switch between a loading position and a storage position. In the storage position, one side 63b of the base end 63a of the support arm 63 abuts against the first component 62a of the support frame 62, thereby maintaining the position of the platform 60. In the loading position, seedlings, fertilizers, and other work materials can be loaded onto the platform 60.

[0062] Regardless of whether the cover 50a of the fertilizer hopper 50 is open or closed, the platform 60 can be rotated, and its position can be changed from the storage position to the placement position. In the placement position, the side opposite to one side 63b, i.e., the other side 63c, abuts against the first component 62a, thereby maintaining the position of the platform 60.

[0063] With the cover 50a of the fertilizer hopper 50 closed, when the placement platform 60 rotates from the storage position to the placement position, the rotation axis of the placement platform 60 is positioned above the fertilizer hopper 50, and the other side 63c of the base end 63a of the support arm 63 abuts against the first component 62a. Thus, the placement platform 60 is positioned above the cover 50a of the fertilizer hopper 50.

[0064] Furthermore, with the fertilizer hopper 50's cover 50a open, when the placement platform 60 rotates from the storage position to the placement position, the other side 63c of the base end 63a of the support arm 63 abuts against the first component 62a. Thus, the placement platform 60 is positioned above the opening of the fertilizer hopper 50. The front end of the placement platform 60 is positioned inside the cover 50a of the fertilizer hopper 50. Therefore, when the fertilizer hopper 50's cover 50a rotates in the closing direction, the front end of the placement platform 60 abuts against the cover 50a of the fertilizer hopper 50, restricting the rotation of the cover 50a. That is, the fertilizer hopper 50's cover 50a remains in the open state.

[0065] For example, with the cover 50a of the fertilizer hopper 50 open and the placement platform 60 in the placement position, a prepared fertilizer bag is placed on the placement platform 60. When replenishing fertilizer to the fertilizer hopper 50, the fertilizer bag placed on the placement platform 60 is opened, and when fertilizer is added from the fertilizer bag to the placement platform 60, the fertilizer falls into the fertilizer hopper 50 through the hole 60a formed in the placement platform 60. In this way, replenishing fertilizer to the fertilizer hopper 50 becomes easy.

[0066] The seedling transplanter 1 of this embodiment includes a traveling body 2, a fertilizer hopper 50, a delivery mechanism 51, a loading platform 60, and a switching mechanism 61. The fertilizer hopper 50 is located on the traveling body 2 and stores fertilizer. The delivery mechanism 51 releases the fertilizer stored in the fertilizer hopper 50. The loading platform 60 can be positioned above the fertilizer hopper 50. The switching mechanism 61 switches the loading platform 60 between a loading position above the fertilizer hopper 50 where it can hold work materials and a storage position to the side of the fertilizer hopper 50.

[0067] Therefore, the seedling transplanter 1 can be equipped with a loading platform 60 above the fertilizer hopper 50, where the loading platform 60 carries the work materials. Furthermore, when not carrying work materials, the loading platform 60 can be retracted into a storage position. Thus, the seedling transplanter 1 can ensure sufficient working space depending on whether work materials are loaded. In other words, the seedling transplanter 1 can expand its working space. Additionally, the seedling transplanter 1 can change its working space according to the work status, thereby improving its operability.

[0068] Fertilizer hoppers 50 are provided at the left and right ends of the vehicle body 2.

[0069] Therefore, in the seedling transplanter 1, which has fertilizer hoppers 50 at the left and right ends respectively, the working space can be further expanded.

[0070] The fertilizer hopper 50 has a cover 50a with an opening at the top that can be opened and closed. The loading platform 60 is held in the loading position with the cover 50a open.

[0071] Therefore, the seedling transplanter 1 can carry work materials on the loading platform 60 with the cover 50a of the fertilizer hopper 50 open. Thus, for example, when fertilizer bags are placed on the loading platform 60 with the cover 50a of the fertilizer hopper 50 open, and fertilizer is being added to the fertilizer hopper 50, fertilizer can be added to the fertilizer hopper 50 without opening or closing the cover 50a. In other words, the seedling transplanter 1 improves workability.

[0072] The mounting platform 60 can switch between the mounting position and the storage position by rotating. The mounting platform 60 rotates in a direction different from the rotation direction of the cover 50a.

[0073] Therefore, regardless of the opening or closing state of the cover 50a, the seedling transplanter 1 can rotate the platform 60 and switch the platform 60 to the placement position or the storage position.

[0074] When the cover 50a is in the open state, the mounting platform 60 restricts the cover 50a from rotating in the closing direction at the mounting position.

[0075] Therefore, the seedling transplanter 1 can prevent the cover 50a from closing when the loading platform 60 is in the loading position. Thus, for example, it can suppress contact between the cover 50a and the work material placed on the loading platform 60.

[0076] The rotation axis of the loading platform 60 is located on the outside of the fertilizer hopper 50 when viewed from above.

[0077] Therefore, when the seedling transplanter 1 is in the storage position, it can prevent the seedling platform 60 from contacting the fertilizer hopper 50, and can prevent the deterioration of the seedling platform 60 and the fertilizer hopper 50. In addition, when the seedling transplanter 1 is in the storage position, for example, it can prevent the seedling platform 60 from protruding in the left and right directions, thus reducing the storage space of the seedling platform 60.

[0078] Multiple holes 60a are formed on the mounting stage 60.

[0079] Thus, for example, when the cover 50a of the fertilizer hopper 50 is open and the loading platform 60 is in the loading position, fertilizer is added to the loading platform 60, and the fertilizer is replenished to the fertilizer hopper 50 through the hole 60a. That is, the operator can easily replenish the fertilizer, and the fertilizer replenishment workability of the seedling transplanter 1 can be improved.

[0080] In the modified seedling transplanter 1, the platform 60 can also rotate around a rotation axis set in the left-right direction.

[0081] In the modified seedling transplanter 1, the cover 50a of the fertilizer hopper 50 can also rotate around a rotating shaft located in the left-right direction and further inward than the fertilizer hopper 50. Additionally, in the modified seedling transplanter 1, the platform 60 can also rotate around a rotating shaft located in the left-right direction and further outward than the fertilizer hopper 50.

[0082] The modified seedling transplanter 1 can also have the following structure.

[0083] like Figure 6 As shown, the seedling transplanter 1 can set the placement platform 60 in an approximate L-shape. Figure 6 This is a schematic diagram showing a modified example of the loading platform 60. The loading platform 60 is positioned to the side of the fertilizer hopper 50, holding fertilizer bags 100 as work materials. Fertilizer can be added to the fertilizer hopper 50 from above. The operator rotates the loading platform 60 upwards, thereby allowing fertilizer to be replenished to the fertilizer hopper 50 from the fertilizer bags placed to the side. The operator can easily replenish fertilizer to the fertilizer hopper 50.

[0084] like Figure 7 As shown, the seedling transplanter 1 can be equipped with multiple layers, such as two layers, of the loading platform 70 along the vertical direction. Figure 7 This is a schematic diagram showing a modified example of the mounting platform 70. The mounting platform 70 rotates horizontally about a shaft 71 that is provided in the vertical direction.

[0085] Therefore, the seedling transplanter 1 can increase the amount of work materials that can be placed on the loading platform 70. In addition, for example, it makes it easier for operators to carry out the work materials from outside the farmland to the seedling transplanter 1.
