Description

[Technical field]

[0001] The present invention relates to a transport device for agricultural work that can store and transport, for example, roughage and the like, and more specifically, to a transport device for agricultural work that can increase the load capacity of stored items and lower the center of gravity of the loading box to ensure running stability. [Background technology]

[0002] Generally, roughage harvested in the field is loaded into a shipping box of a transport device by a harvester and transported to a grass collection area, etc. Then, the roughage collected at the grass collection area is made into roll bales using a roll baler, etc., or is given as it is to livestock as feed.

[0003] [Patent Document 1] JP 2013-111036 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the conventional transport device, as shown in Fig. 7, a vertically long packing box 61 is provided directly above the tires 3, which inevitably results in a high center of gravity of the packing box 61. Also, if the roughage contained in the packing box 61 contains a lot of moisture, the contents become very heavy, causing a problem of instability when traveling through rough farmland.

[0005] To address this issue, it is possible to mount the tires so that they extend out to the sides of the cargo box and lower the cargo box into the gap between the left and right tires. However, this poses the problem that the width of the transport device becomes larger from side to side, making it less maneuverable.

[0006] SUMMARY OF THE PRESENT EMBODIMENT The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a transport device that can lower the center of gravity of a packing box and increase the load capacity of the contents. [Means for solving the problem]

[0007] That is, in order to solve the above-mentioned problems, the present invention provides a transport device including a vertically long container for storing contents and left and right tires for running in a field while supporting the container, the container being supported by the left and right tires. The tire has a bottom surface below the top surface of the tire. A lower housing portion; The left and right side portions are provided above the upper surface portions of the left and right tires and between the widths of the left and right tires. The container is configured to have an upper storage section and a pressure plate for pressing the contents of the container rearward.

[0008] With this configuration, the items can be stored in the gap between the left and right tires, so the center of gravity of the box can be lowered and a large amount of items can be loaded. Also, even if a step occurs between the lower storage section and the upper storage section, the items can be pushed backward by the pressure plate, so there is no risk of items being left behind when ejected.

[0009] In the present invention, the rear surface of the packing box facing upward from the tire is configured to be inclined.

[0010] With this configuration, a large clearance can be secured between the tires and the cargo box, and the tires will not come into contact with the cargo box even when traveling on rough farmland.

[0011] Furthermore, a sloping portion is provided on the bottom surface between the lower storage portion and the upper storage portion, the sloping portion being sloping downward toward the center.

[0012] With this configuration, when the contents are placed in the container from above, the contents can be stored in the lower storage section along the slope, eliminating the risk of bridges or the like forming voids.

[0013] Also, the pressure plate is constituted by a single plate-like member that contacts the inner wall of the packing box.

[0014] With this configuration, even if there is a step or a slope between the lower storage section and the upper storage section, the contents can be reliably pushed backward by the pressure plate.

[0015] The pressure plate located in the lower housing portion is provided so as to have a vertical surface, and the pressure plate located in the upper housing portion is inclined so that the upper portion faces forward.

[0016] With this configuration, when the contents are pressed by the pressure plate, the contents can be lifted upward and transported, so that the pressing load can be reduced and the contents can be transported. Effect of the Invention

[0017] According to the present invention, in a transport device including a vertically long container for storing contents and left and right tires for running in a field while supporting the container, the container is supported by the left and right tires. The tire has a bottom surface below the top surface of the tire. A lower housing portion; The left and right side portions are provided above the upper surface portions of the left and right tires and between the widths of the left and right tires. Since the box is configured to have an upper storage section and a pressure plate that presses the contents of the box backward, the contents can be stored in the gap between the left and right tires, the center of gravity of the box can be lowered, and a large load capacity of the contents can be secured. Also, even if a step occurs between the lower storage section and the upper storage section, the contents can be pressed backward by the pressure plate, so there is no risk of any contents being left behind.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0020] The transport device 1 in this embodiment is used by being towed by a towing vehicle such as a tractor, and as shown in FIG. 1, is configured with a packing box 2 for storing contents, tires 3 that enable the device to run in a field while supporting the packing box 2, and a discharge section 5 that discharges the contents stored in the packing box 2 from the rear. As shown in FIG. 5, the packing box 2 is configured with a lower storage section 21 that is provided so as to enter the gap between the left and right tires 3, an upper storage section 22 provided on the upper side of the tires 3, and a pressing mechanism 4 that presses the contents stored in the lower storage section 21 and the upper storage section 22 toward the discharge section 5 at the rear. By configuring the device in this way, the center of gravity of the packing box 2 can be lowered downward to ensure running stability, and a large loading capacity of the contents can be secured. Hereinafter, this embodiment will be described in detail.

[0021] First, as shown in Fig. 1, the cargo box 2 is configured to be elongated vertically along the traveling direction, and on its inside, as shown in Fig. 5, is provided with a lower storage section 21 provided so as to enter the gap between the left and right tires 3, an upper storage section 22 provided above the left and right tires 3, and an inclined section 23 provided at the boundary between the lower storage section 21 and the upper storage section 22. By configuring it in this way, the lower storage section 21 of the cargo box 2 and the tires 3 overlap in the vertical direction in a side view (see Fig. 2), and the cargo box 2 and the tires 3 overlap in the horizontal direction in a plan view (see Fig. 3).

[0022] In this packing box 2, the lower storage section 21 is provided so as to overlap the tire 3 from the upper surface portion toward the center within a range of 30% to 50%, and is configured so that contents can be placed and stored on the bottom surface portion 21a. In addition, the side surface portions 21b provided on both sides of the bottom surface portion 21a of this lower storage section 21 are provided so as to stand upright in the vertical direction, and plate-shaped rails 21c for guiding the pressure plate 41 described later are provided on the inside thereof.

[0023] On the other hand, the upper storage section 22 is provided so as to overlap 70% or more (preferably 90% or more) of the width of each tire 3, thereby ensuring a large loading capacity of the stored items. A backing plate 24 (see FIG. 1) that is higher than the side surface 22a on the opposite side is provided on the upper portion of one side surface 22a of the upper storage section 22, thereby preventing the stored items from spilling out from the opposite side when they are inserted.

[0024] An inclined portion 23 inclined toward the center downward is provided at the boundary between the lower storage portion 21 and the upper storage portion 22. This inclined portion 23 makes it easier to store the stored items in the lower storage portion 21 when the stored items are inserted, and the stored items slide along this inclined portion 23 and are stored in the lower storage portion 21. The angle of this inclined portion 23 is set within a range of about 10 degrees to 30 degrees taking into consideration the load capacity and storage in the lower storage portion 21, but is not limited to this.

[0025] On the other hand, as shown in Figs. 1 and 4, the tires 3 supporting the cargo box 2 are provided in two pairs, one in front and one in back, at the rear part of the cargo box 2 configured in a vertically long shape, and the axles 31 provided across the left and right sides are supported by suspensions 32 (see Fig. 4) to allow the box 2 to swing up and down. When the tires 3 are swung up and down in this way, there is a possibility that the tires 3 may hit the back plate 22b (see Fig. 5) of the upper storage section 22. Therefore, here, the back plate 22b of the cargo box 2 above the tires 3 is also inclined, thereby ensuring the swing distance above the tires 3. The tires 3 are provided between ribs 25 provided intermittently in the front-rear direction of the cargo box 2 (see Fig. 1). This rib 25 is provided so as to protrude laterally from the upper storage section 22 to the lower storage section 21 so as to incline toward the lower end, thereby ensuring the strength of the cargo box 2 and lowering the center of gravity of the cargo box 2 by storing the tire 3 between the ribs 25.

[0026] The contents of the packing box 2 supported by the tires 3 in this manner are pressed backward by the pressing mechanism 4. This pressing mechanism 4 is configured with a pressing plate 41 provided so as to contact the inner wall of the packing box 2, a rod 42 that presses this pressing plate 41 backward, a hydraulic device (not shown), and the like.

[0027] Among these, the pressing plate 41 is provided so as to contact the inner walls of the lower storage section 21, the inclined section 23, and the upper storage section 22, and is configured to press the stored items backward to discharge the stored items from the discharge section 5. The pressing plate 41 can be configured as a plate that is entirely aligned in the vertical direction, but this configuration requires a large load when pressing the pressing plate 41. On the other hand, if the pressing plate 41 is entirely inclined, it is necessary to incline the guide of the lower storage section 21 and the part that contacts the inclined section 23 at the boundary with the upper storage section 22, making it difficult to form the pressing plate 41. Therefore, in this embodiment, the lower pressing plate 41a at the position where the lower storage section 21 and the inclined section 23 are present is made vertical, and the upper pressing plate 41b at the position where the upper storage section 22 is present is inclined with its upper part facing forward (toward the tractor).

[0028] The pressing mechanism 4 that presses the pressing plate 41 thus constructed is configured to extend and retract the rod 42 by the force of the hydraulic device. Of these, the rod 42 is provided so as to press the portion of the lower housing part 21 that requires a large load, and is configured so that the frame can be tilted from there to press the entire surface of the pressing plate 41. On the other hand, the hydraulic device is composed of a hydraulic cylinder that slides in the front-rear direction by hydraulic pressure from the tractor.

[0029] The discharge section 5 is designed to discharge the stored items that have been pressed backward by the pressure plate 41 at a grass collection area or the like, and is configured to rotate upward using a hydraulic cylinder 52 around a rotating section 51 provided at the top of the boundary with the packing box 2, thereby opening the rear section.

[0030] Next, the operation of the transport device 1 thus configured will be described.

[0031] First, before storing the contents in the packing box 2, the transport device 1 is connected to a connector provided in the center of the rear of a tractor (not shown), and the hydraulic pump of the tractor is connected. At this time, the pressure plate 41 of the transport device 1 is positioned in the front.

[0032] In this state, the contents are dumped into the packing box 2 using a harvester or the like, and at this time, the contents are dumped into the packing box 2 from the side where the backing plate 24 is not present.

[0033] Then, the contents fall from the upper storage section 22, hit the inclined portion 23 at the boundary between the upper storage section 22 and the lower storage section 21, and are stored in the lower storage section 21 in the center. Then, the contents are sequentially added and stored up to the upper storage section 22, and at this time, the contents stored in the packing box 2 are positioned below the upper surface of the tire 3, so that the center of gravity can be lowered even if the contents contain a lot of moisture.

[0034] Then, with the contents thus stored, the container is moved to a specified grass collection area, where the discharge section 5 provided at the rear of the packing box 2 is opened, and the contents are discharged while the pressure plate 41 is moved backward.

[0035] When moving the pressure plate 41 backward, the contents in the lower storage section 21 of the packing box 2 are pushed backward using the lower pressure plate 41a, and the contents are pushed backward using the inclined upper pressure plate 41b. At this time, the inclined upper pressure plate 41b pushes the contents backward while lifting them upward along its inclination, so that the load applied to the rod 42 can be reduced and the pressure plate 41 can be pushed.

[0036] After the pressure plate 41 has been moved to the rearmost position in this manner and the storage section has been discharged, the discharge section 5 is closed and the pressure plate 41 is returned to the frontmost position.

[0037] As described above, according to the embodiment, in the transport device 1 including the elongated container 2 for storing contents and the left and right tires 3 for running in a field while supporting the container 2, the container 2 is supported by the left and right tires 3. The bottom surface portion 21a is provided in the gap between the tire 3 and the upper surface portion of the tire 3. A lower storage section 21; The left and right side portions 22a are provided above the upper surface portions of the left and right tires 3 and between the widths of the left and right tires 3.Since the box 2 is configured to have an upper storage section 22 and a pressure plate 41 for pressing contents in the box 2 backward is provided, contents can be stored in the gap between the left and right tires 3, and as shown in Fig. 6, the center of gravity of the box 2 can be lowered and a large load capacity of contents can be secured. Even if there is a step such as an inclined section 23 between the lower storage section 21 and the upper storage section 22, contents can be pressed backward by the pressure plate 41, so that contents are not left behind when discharged.

[0038] The present invention is not limited to the above-described embodiment, but can be embodied in various forms.

[0039] For example, in the above embodiment, the boundary portion between the lower storage section 21 and the upper storage section 22 is inclined so that the stored items fall into the lower storage section 21, but this boundary portion may be horizontal or curved.

[0040] In the above embodiment, only the upper portion of the pressure plate 41 is inclined, but the pressure plate 41 may be inclined as a whole, or the pressure plate 41 may be vertical as a whole.

[0041] Furthermore, in the above embodiment, the side surface portion 22a of the upper storage portion 22 is made to stand upright, but this side surface portion may be inclined so as to widen upward. [Explanation of symbols]
