Description

[Technical Field]

[0001] The present invention relates to a harvester. [Background Art]

[0002] For example, as disclosed in Patent Document 1, there is a harvester (combine) provided with a boarding-type driving section (control section) having a driver's seat (seat), and an umbrella holder (clamp fitting) capable of holding a sunshade (parasol) for the driving section. [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Utility Model Laid-Open Publication No. Sho 58-107741 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] There is a demand for a harvester that can prevent sunlight from the rear from hitting the occipital region of a driver seated on the driver's seat. In the case of a conventional harvester that allows use of a sunshade, since the sunshade is held on the right outer side surface of the control tower, a large sunshade must be used to position the sunshade in a region rearward of the driver seated on the driver's seat, which easily causes problems such as increased wind resistance on the sunshade.

[0005] The present invention provides a harvester that makes it difficult for problems caused by using a sunshade to occur, while allowing the sunshade to prevent sunlight from the rear from hitting the occipital region of the driver. [Means for Solving the Problem]

[0006] The harvester according to the present invention includes: The machine comprises a ride-on driver's seat, a harvesting and transporting unit located on one side of the machine in the width direction relative to the driver's seat, which harvests crops from the field and transports the harvested crops toward the rear of the machine, a separation unit located behind the harvesting and transporting unit which receives crops from the harvesting and transporting unit and separates the fruit from the supplied crops, and an introduction path cover which covers the crop introduction path through which crops from the harvesting and transporting unit are introduced into the crop receiving inlet of the separation unit, and an umbrella holder capable of holding a sunshade umbrella for the driver seated in the driver's seat is located at the corner between the front plate and the side vertical plate of the introduction path cover. In contrast, at a position adjacent to the corner of the vertical plate portion, so as not to protrude forward of the front plate portion. When attached, the umbrella holder is positioned on the side where the driver's unit is located relative to the harvesting and transporting unit, on the side where the driver's unit is located, so as to be on the inner side of the machine body, beyond the outer side of the driver's seat, and further rearward than the front end of the driver's seat.

[0007] With this configuration, by using the umbrella holder to hold the sunshade umbrella, it can be held further inward than the outer edge of the side of the aircraft body relative to the driver's seat, and further rearward than the front edge of the aircraft body relative to the driver's seat. Therefore, even if a smaller sunshade umbrella is used than before, the sunshade umbrella will be positioned behind the driver seated in the driver's seat, making it less likely for problems such as wind exposure from the sunshade umbrella to occur, while preventing sunlight from hitting the back of the driver's head from behind. This configuration allows for the inexpensive installation of an umbrella holder by utilizing an access path cover as the component to which the umbrella holder is attached.

[0008] In this invention, The umbrella holder is preferably located further rearward than the rear end of the driver's seat.

[0009] With this configuration, by using the umbrella holder to hold the sunshade umbrella, it can be held further back on the aircraft than the rear end of the driver's seat. Therefore, even if a smaller sunshade umbrella is used compared to conventional designs, the sunshade umbrella will be positioned behind the driver seated in the driver's seat, making it less likely for problems such as wind exposure from the sunshade umbrella to occur, while still preventing sunlight from hitting the back of the driver's head from behind.

[0010] In this invention, The umbrella holder is preferably located within the width of the driver's seat.

[0011] With this configuration, by using the umbrella holder to hold the sunshade umbrella, it can be held within the width of the driver's seat. Therefore, even if a smaller sunshade umbrella is used compared to conventional designs, the sunshade umbrella will be positioned behind the driver seated in the driver's seat, making it less likely for problems such as wind exposure from the sunshade umbrella to occur, while still preventing sunlight from hitting the back of the driver's head from behind.

[0012] In this invention, Preferably, the umbrella holder is located on the side of the harvesting and conveying unit that is located, rather than the center of the driver's seat in the width direction of the machine body.

[0013] With this configuration, by using the umbrella holder to hold the sunshade umbrella, it can be held on the side where the harvesting and conveying unit is located, rather than the center of the machine's width relative to the driver's seat. Therefore, even if a smaller sunshade umbrella is used compared to conventional designs, the sunshade umbrella will be positioned behind the driver seated in the driver's seat, making it less likely for problems such as wind exposure from the sunshade umbrella to occur, while still preventing sunlight from hitting the back of the driver's head from behind.

[0014]

[0015]

[0016] In this invention, The umbrella holder preferably includes a cylindrical portion into which the handle of the sunshade umbrella can be inserted from above, a receiving portion provided at the lower part of the cylindrical portion to receive the handle inserted into the cylindrical portion, and a fixing member provided at the upper part of the cylindrical portion to press the handle and fix it to the cylindrical portion.

[0017] According to this configuration, when the handle is inserted into the cylinder from above, the handle is received by the receiving portion and does not fall out of the cylinder. If the handle is fixed to the cylinder by the fixing member, the handle is held by the cylinder without shaking. Therefore, the sunshade can be held by the umbrella holder without shaking through a simple operation that only requires inserting the handle into the cylinder and operating the fixing member.

[0018] In the present invention, it is preferable that the receiving portion is provided with an engaging portion that engages with the tip end of the handle.

[0019] According to this configuration, when the handle is inserted into the cylinder, the tip end of the handle is held by the engaging portion so as not to shift. Therefore, the sunshade can be easily held by the umbrella holder without shaking without performing a special operation to prevent shaking of the tip end of the handle.

[0021] Hereinafter, an embodiment which is an example of the present invention will be described based on the drawings. In the following description, regarding the traveling body of an edamame harvester (an example of a "harvester"), the direction of arrow F shown in FIGS. 1 and 2 is defined as "front side of the body", the direction of arrow B is "rear side of the body", the direction of arrow U shown in FIG. 1 is "upper side of the body", the direction of arrow D is "lower side of the body", the direction of arrow L shown in FIG. 2 is "left side of the body", and the direction of arrow R is "right side of the body". The left-right direction of the body corresponds to the width direction of the body.

[0022] [Overall configuration of the edamame harvesting machine] As shown in Figures 1 and 2, the edamame harvester comprises a machine frame 1 constructed by connecting multiple steel materials such as square pipes, and a mobile body 3 having a pair of left and right crawler-type travel devices 2 located at the bottom of the machine frame 1. A ride-on driver's unit 4 is provided on the right side of the front of the mobile body 3. The driver's unit 4 is equipped with a driver's seat 5, a control tower 6 located in front of the driver's seat 5, and a side panel 7 located to the left of the driver's seat 5. To the left of the driver's unit 4 is a crop harvesting and transporting unit 8 that harvests edamame as a crop to be planted in the field and transports the harvested edamame to a predetermined location on the mobile body 3. Behind the crop harvesting and transporting unit 8 is a separation unit 9 that receives edamame from the crop harvesting and transporting unit 8 and separates the beans A from the stems of the supplied edamame. A storage unit 10 is provided on the right side of the mobile body 3 for collecting and storing the beans A obtained by the separation unit 9.

[0023] [Regarding the harvesting and transporting department] As shown in Figures 1 and 2, the crop harvesting and transporting unit 8 is equipped with a divider 11 located at the front of the unit to separate the edamame to be harvested from the edamame being planted in the field, a pre-crop harvesting and transporting unit 8A that pulls the edamame separated by the divider 11 out of the field for harvesting and transports them upward and rearward to an intermediate point in the crop harvesting and transporting unit 8, and a post-crop harvesting and transporting unit 8B that takes over the edamame from the pre-crop harvesting and transporting unit 8A and transports them upward and rearward to the transport end of the crop harvesting and transporting unit 8. Below the pre-crop harvesting and transporting unit 8A, a mulch cutter 12 is provided to cut the mulch laid in the field before the edamame are pulled out, so that it does not rise along with the edamame being pulled out. On both sides of the mulch cutter 12, there are sleds 13 that hold down the mulch.

[0024] As shown in Figures 1 and 2, the previous crop harvesting and conveying unit 8A is equipped with left and right endless rotating conveying belts 14 aligned in the lateral direction of the traveling machine body 3. The left and right endless rotating conveying belts 14 are installed in a rearward-upward position, with the left side being higher towards the left in the conveying direction. The left and right endless rotating conveying belts 14 are driven to rotate so that the conveying path side portions 14a along the conveying path move from the conveying start end to the conveying end end of the previous crop harvesting and conveying unit 8A. Rollers 15 are provided at multiple locations on the conveying path side portions 14a of each of the left and right endless rotating conveying belts 14, supporting the conveying path side portions 14a from the inside of the endless rotating conveying belts 14.

[0025] In the previous crop harvesting and conveying section 8A, the edamame stalks from the divider 11 are gripped and lifted by the conveying path sides 14a of the endless rotating conveying belts 14 on the left and right, thereby pulling the edamame out of the field. The pulled-out edamame are then conveyed vertically upward and backward toward the next crop harvesting and conveying section 8B.

[0026] As shown in Figures 1 and 2, the subsequent crop harvesting and conveying section 8B is equipped with left and right endless rotating conveying belts 16 aligned in the lateral direction of the traveling machine body 3. The left and right endless rotating conveying belts 16 extend from below the end of the previous crop harvesting and conveying section 8A to the front of the separation section 9. The left and right endless rotating conveying belts 16 are driven to rotate so that the conveying path sides 16a along the conveying path move from the conveying start end to the conveying end end of the subsequent crop harvesting and conveying section 8B. Rollers 17 are provided at multiple locations in the conveying direction on the conveying path sides 16a of each of the left and right endless rotating conveying belts 16, supporting the conveying path sides 16a from the inside of the endless rotating conveying belt 16.

[0027] In the subsequent crop harvesting and conveying section 8B, the edamame beans from the previous crop harvesting and conveying section 8A are taken over and held by the conveying path sides 16a of the endless rotating conveying belts 16 on the left and right, and conveyed in a vertical position upward and rearward to a predetermined location on the traveling machine 3.

[0028] [Regarding the separation section] As shown in Figures 1 and 2, a crop introduction path 18 is provided behind the crop harvesting and conveying section 8 to introduce edamame from the crop harvesting and conveying section 8 into the crop receiving inlet 9a of the separation section 9. The crop introduction path 18 is equipped with a supply device 20 that changes the orientation of the vertically oriented edamame from the crop harvesting and conveying section 8 to a horizontal position and supplies it to the conveying start end of the endless rotating conveyor body 19 of the separation section 9. As shown in Figures 1 and 2, the crop introduction path 18 is covered by an introduction path cover 21. The introduction path cover 21 prevents dust generated from the edamame whose orientation is changed by the supply device 20 from scattering.

[0029] As shown in Figures 1 and 2, in the crop introduction path 18, the edamame from the crop harvesting and conveying section 8 is changed in orientation from vertical to horizontal by the supply device 20, and the base of the edamame plant in the horizontal position is supplied by the supply device 20 to the conveying start end of the endless rotating conveyor 19 of the separation section 9. The horizontally positioned edamame is conveyed toward the rear of the separation section 9 by the endless rotating conveyor 19, and the tip of the edamame is introduced into the separation chamber from the crop receiving inlet 9a and supplied to the pre-separation processing section 22 and the post-separation processing section 23. In the pre-separation processing section 22 and the post-separation processing section 23, the tip passes between the vertically aligned separation rotating bodies 22a and 23a, and the beans A are separated from the stem by the separation rotating bodies 22a and 23a.

[0030] [Regarding the storage section] The storage unit 10 receives the fruit A obtained by the separation unit 9 via a lateral conveyor belt 24 extending from the rear and below the separation unit 9 to the rear of the storage unit 10, and collects and stores the supplied fruit A. The storage unit 10 is composed of a belt conveyor that extends along the front-rear direction of the traveling machine body 3. During harvesting travel, the belt conveyor is driven in the forward direction, so that the collected fruit A is sequentially transported to the front of the storage unit 10, and the fruit A is stored along the entire length of the storage unit 10. When the belt conveyor is driven in the backward direction, the stored fruit A is discharged from the storage unit 10 to the rear, and the fruit A can be received in a container installed behind the storage unit 10.

[0031] [Regarding umbrella holders] As shown in Figure 1, an umbrella holder 25 is provided, and by holding the sunshade umbrella 26 with the umbrella holder 25, it is possible to create shade for the driver seated in the driver's seat 5 using the sunshade umbrella 26. Note that the sunshade umbrella 26 shown in Figures 1 and 2 is an example, and the shape and size of the sunshade umbrella 26 are not limited to this embodiment.

[0032] As shown in Figure 2, the umbrella holder 25 is located on the side where the driver's unit 4 is positioned relative to the crop harvesting and transporting unit 8, positioned inward from the outer lateral end 5A of the driver's seat 5, and further rearward from the front end 5F of the driver's seat 5. As a result, when a sunshade umbrella 26 of a certain size is held using the umbrella holder 25, the sunshade umbrella 26 is positioned behind the driver seated in the driver's seat 5, preventing sunlight from hitting the back of the driver's head from behind.

[0033] More specifically, as shown in Figure 2, the umbrella holder 25 is located on the side where the driver's unit 4 is positioned relative to the crop harvesting and transporting unit 8, on the side where the driver's unit 4 is positioned, on the side of the driver's seat 5 that is located on the side of the machine

[0034] As shown in Figure 2, the umbrella holder 25 is located within the width 5W of the driver's seat 5 on the side where the driver's unit 4 is located relative to the crop harvesting and transporting unit 8, and is positioned further rearward than the front end 5F of the driver's seat 5.

[0035] As shown in Figure 2, the umbrella holder 25 is located within the width 5W of the driver's seat 5 on the side where the driver's unit 4 is located relative to the crop harvesting and transporting unit 8, and is positioned further rearward than the rear end 5R of the driver's seat 5.

[0036] As shown in Figure 2, the umbrella holder 25 is located on the side where the driver's unit 4 is located relative to the crop harvesting and conveying unit 8, on the side where the crop harvesting and conveying unit 8 is located

[0037] As shown in Figure 2, the umbrella holder 25 is located on the side where the driver's unit 4 is located relative to the crop harvesting and conveying unit 8, on the side where the crop harvesting and conveying unit 8 is located and on the rear side of the machine, beyond the rear end 5R of the driver's seat 5.

[0038] The umbrella holder 25 is attached to the access path cover 21, as shown in Figures 2 and 3. The access path cover 21 is used as a component to hold the umbrella holder 25.

[0039] As shown in Figures 3 and 4, the umbrella holder 25 has a cylindrical portion 27 oriented vertically on the machine, a receiving portion 28 provided at the lower part of the cylindrical portion 27, and a knobbed bolt 29 as a fixing member provided at the upper part of the cylindrical portion 27. The knobbed bolt 29 is provided at two locations in the circumferential direction on the upper part of the cylindrical portion 27. The cylindrical portion 27 is composed of a vertical plate portion 21a of the introduction path cover 21 and a bent sheet metal connected to the vertical plate portion 21a. The bent sheet metal is connected to the vertical plate portion 21a by welding. The cylindrical portion 27 does not protrude in front of the front surface of the introduction path cover 21. In this embodiment, the cylindrical portion 27 is formed in a triangular shape, but it is not limited to a triangle; it may be a cylindrical portion of any shape, such as a square, ellipse, or other non-circular or circular shape.

[0040] In the umbrella holder 25, as shown in Figure 4, when the handle 30 of the sunshade umbrella 26 is inserted into the cylindrical part 27 from above, the handle 30 is received by the receiving part 28 to prevent it from falling out. By tightening the knobbed bolt 29, the handle 30 is pressed toward the vertical plate part 21a by the knobbed bolt 29 and fixed to the cylindrical part 27, and the sunshade umbrella 26 is held by the umbrella holder 25 so that it does not rattle. The knobbed bolt 29 presses the handle 30 in two different directions from two points in the circumferential direction of the cylindrical part 27, so the handle 30 is firmly fixed to the cylindrical part 27.

[0041] As shown in Figure 4, the receiving portion 28 is provided with an engagement hole 31 as an engaging portion. When the handle 30 is inserted into the cylindrical portion 27, the tapered tip 30a of the handle 30 enters the engagement hole 31, and the handle 30 and the receiving portion 28 engage through the engagement hole 31, preventing the handle 30 from wobbling. Simply by inserting the handle 30 into the cylindrical portion 27, the tip 30a of the handle 30 and the receiving portion 28 engage, holding the tip 30a in place so that it does not wobble.
