Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a conveying device, when unnecessary substances such as stems and leaves cut from carrots are conveyed together with crops such as carrots, it is necessary to manually remove the unnecessary substances. When the conveying speed is high for efficiency improvement, it is necessary to increase the number of workers for the operation of manually removing unnecessary substances from the conveying device. Therefore, a conveying device capable of reducing such work has been desired.

[0005] Therefore, an object of the present invention is to provide a conveying device capable of reducing the work of removing unnecessary substances.

Means for Solving the Problems

[0006] The conveying device of the present invention includes a first conveyor for conveying crops, a second conveyor provided on the downstream side in the conveying direction of the first conveyor for conveying the crops from the first conveyor, and a width direction extending member provided between the first conveyor and the second conveyor and extending in the width direction of the first conveyor and the second conveyor.

[0007] According to this invention, unwanted materials being transported on the conveying surface get caught on the widthwise extending member and fall, sending the unwanted materials to the lower part of the conveying device. On the other hand, the main roots of carrots and the like are not sent to the lower part of the conveying device by the first conveyor and rotating body, but are transported directly by the second conveyor. In this way, the work of removing unwanted materials can be reduced.

[0008] In the present invention, the widthwise extending member is preferably a rotating body that can rotate around a rotation axis extending in the width direction of the first conveyor and the second conveyor.

[0009] In this configuration, the widthwise extending member, which is a rotating body, rotates as the conveyed material passes over it, for example, if it is configured to rotate freely. Due to the rotation of the widthwise extending member, unwanted materials such as stems and leaves become entangled in it. As the widthwise extending member rotates further, the unwanted materials entangled in it are sent to the bottom of the conveying device. On the other hand, the main roots of carrots and the like are not sent to the bottom of the conveying device by the first conveyor and the rotating body, but are conveyed directly by the second conveyor. In this way, the work of removing unwanted materials can be reduced.

[0010] In the present invention, it is preferable that the rotating body rotates such that the conveying surface is in a direction opposite to the conveying direction of the first conveyor and the conveying direction of the second conveyor.

[0011] In this configuration, the first conveyor and the rotating body are designed to grip the conveyed object being transported on the conveying surface and then send it downwards to the conveying device. For example, if the conveyed object being transported by the conveying device is of a certain size, such as a carrot, then when the first conveyor and the rotating body are in contact, or when the gap between the first conveyor and the rotating body is narrowed, unwanted parts such as the stems and leaves of the carrot are sent downwards to the conveying device by the first conveyor and the rotating body. On the other hand, the main root of the carrot is not sent downwards to the conveying device by the first conveyor and the rotating body, but is instead transported by the second conveyor. In this way, the work required to remove unwanted parts can be reduced.

[0012] In the present invention, a crop separation unit is provided for separating the crop into a harvestable portion and a stem and leaf portion while it is being transported, and it is preferable that the crop separation unit is composed of the first conveyor and the rotating body.

[0013] Carrots that have not been cut into main root and stem / leaves by the cutting device may be transported by the conveying device. Such carrots require manual cutting of the stems and leaves. By having the first conveyor and waste collection roller tear off the stems and leaves of the carrots, the first conveyor and waste collection roller function as crop separators that separate the carrots into main root and stem / leaves while they are being transported, thereby reducing the amount of manual work required to cut off the stems and leaves of the carrots.

[0014] In the present invention, it is preferable that the height position of the upstream end of the second conveyor in the conveying direction is lower than the height position of the downstream end of the first conveyor in the conveying direction.

[0015] In this configuration, when conveyed material is transported from the first conveyor to the second conveyor, the material falls from the downstream end of the first conveyor in the transport direction to the upstream end of the second conveyor in the transport direction. As a result, the transport speed of the material in the transport direction of the conveying device is reduced. This makes it possible to create a configuration in which unwanted materials such as carrot stems and leaves are more easily fed downwards into the conveying device by the first conveyor and the rotating body because the transport speed is reduced near the rotating body.

[0016] In the present invention, it is preferable that the height position of the rotating body is lower than the height position of the downstream end of the first conveyor in the conveying direction.

[0017] In this configuration, when the conveyed material is transported on the rotating body, it falls onto the rotating body from the downstream end of the first conveyor in the transport direction. As a result, the transport speed of the conveyed material in the transport direction of the conveying device is reduced. This makes it possible to create a configuration in which unwanted materials such as carrot stems and leaves are more easily fed to the lower part of the conveying device by the first conveyor and the rotating body due to the reduced transport speed on the rotating body.

[0018] In the present invention, it is preferable that the transport speed of the first conveyor is greater than the transport speed of the second conveyor.

[0019] With this configuration, when the conveyed material is transported from the first conveyor to the second conveyor, the conveying speed of the material decreases. As a result, unwanted materials such as carrot stems and leaves are more easily fed to the lower part of the conveying device by the first conveyor and the rotating body because the conveying speed decreases near the rotating body.

[0020] In the present invention, a first transmission shaft is provided at the downstream end of the first conveyor in the conveying direction and transmits power to the first conveyor, and it is preferable that the rotational speed of the rotating body is greater than the rotational speed of the first transmission shaft.

[0021] With this configuration, when the conveyed material is transported on the rotating body, the transport speed of the material is reduced. As a result, unwanted materials such as carrot stems and leaves are more easily fed to the lower part of the conveying device by the first conveyor and the rotating body because the transport speed on the rotating body is reduced.

[0022] In the present invention, it is preferable that the system includes a first transmission shaft provided at the downstream end of the first conveyor in the conveying direction and transmitting power to the first conveyor, a second transmission shaft provided at the upstream end of the second conveyor in the conveying direction and rotating in conjunction with the driving of the second conveyor, a first gear that rotates integrally with the first transmission shaft, a second gear that rotates integrally with the second transmission shaft, a third gear that rotates integrally with the rotating body, and a chain stretched between the first gear, the second gear, and the third gear.

[0023] This configuration allows a single power source to drive the first conveyor, the second conveyor, and the rotating body, thus enabling cost reductions and a reduction in the number of components compared to configurations with multiple power sources.

[0024] In the present invention, it is preferable that a deceleration plate member is provided which abuts on the conveyed object being conveyed by the second conveyor to decelerate the conveying speed of the conveyed object.

[0025] According to this configuration, when the conveyed object is conveyed from the first conveyor to the second conveyor, the conveying speed of the conveyed object becomes smaller. As a result, unnecessary objects such as the stems and leaves of carrots can be easily fed downward of the conveying device by the first conveyor and the rotating body because the conveying speed becomes smaller near the rotating body.

[0026] In the present invention, it is preferable that the working vehicle is provided with the conveying device described above.

[0027] According to this configuration, it becomes possible to reduce the work of removing unnecessary objects with the working vehicle by the conveying device described above.

[0028] In the present invention, it is preferable that the crop processing device is provided with the conveying device described above.

[0029] According to this configuration, it becomes possible to reduce the work of removing unnecessary objects with the crop processing device by the conveying device described above.

In the following description, unless otherwise specified, the direction of arrow F in the drawings will be "forward", the direction of arrow B will be "backward", the direction of arrow L will be "left", and the direction of arrow R will be "right". Also, the direction of arrow U in the drawings will be "up", and the direction of arrow D will be "down".

[0032] [Overall configuration of the carrot harvesting machine] Figures 1 and 2 show an example of a work vehicle, a carrot harvesting machine. The carrot harvesting machine comprises a traveling body 1, an engine E, a driver's compartment 2 where the driver sits, a harvesting unit 3 for harvesting crops (carrots C in this embodiment) from the field, a cutting device 4 for cutting the carrots C into the harvesting target part (main root) and other parts (stem and leaves) (corresponding to the "stem and leaf part" of the present invention), a conveying device 5, a bagging unit 6, and a platform 9 on which the worker (assistant) stands while performing the work.

[0033] The mobile unit 1 comprises left and right crawler tracks 7 and a mobile frame 8. The mobile frame 8 is supported by the left and right crawler tracks 7.

[0034] In this embodiment, the driver's unit 2 is located on the right side of the front of the vehicle body 1, in the left-right direction of the vehicle body. The driver's unit 2 includes a driver's seat 10 where the driver sits, and a side cover 11. Below the driver's seat 10, an engine room 12 is formed to house the engine E. The engine room 12 is covered from the outside of the vehicle body (the right side in this embodiment) by the side cover 11.

[0035] The cutting device 4 is configured to cut the carrot C, which is being transported by the left and right conveyor belts 13, into its main root and stem / leaves. The main root of the carrot C, after being cut by the cutting device 4, will fall onto the conveyor 5.

[0036] The bagging section 6 bags the carrots C from the conveying device 5 into flexible container bags (hereinafter referred to as "flexible containers") 13.

[0037] [Configuration of the conveying device] As shown in Figures 2 and 3, the conveying device 5 includes two side walls 20 provided on both sides in the width direction of the conveying device 5, a first conveyor 21 located upstream in the conveying direction and conveying carrots C that have fallen from the cutting device 4, and a second conveyor 22 provided downstream in the conveying direction of the first conveyor 21 and conveying carrots C from the first conveyor 21. Furthermore, a waste material collection roller 23 (corresponding to the "width-extending member" and "rotating body" of the present invention) is provided between the first conveyor 21 and the second conveyor 22. The first conveyor 21, the second conveyor 22, and the waste material collection roller 23 are arranged between (inside) the two side walls 20.

[0038] In this embodiment, the first conveyor 21 is a bar conveyor having a plurality of bars extending in the width direction of the first conveyor 21 at predetermined intervals. The first conveyor 21 includes a first bar conveyor body 31 having a plurality of metal bars, a first free-rotating shaft 32 provided on the upstream side in the conveying direction and configured to rotate freely, and a first drive shaft 33 (corresponding to the "first transmission shaft" of the present invention) provided on the downstream side in the conveying direction and transmitting power to the first bar conveyor body 31. The first bar conveyor body 31 is provided across the first free-rotating shaft 32 and the first drive shaft 33.

[0039] As shown in Figure 4, in this embodiment, the first drive shaft 33 is configured in a cylindrical shape and includes an inner cylindrical member 33A that abuts against the inside of the first bar conveyor body 31, and two drive gears 33B that engage with one edge portion and the other edge portion of the first bar conveyor body 31. The inner cylindrical member 33A is located between the two drive gears 33B. The inner cylindrical member 33A is configured to rotate integrally with the first drive shaft 33. This configuration allows it to abut against the first bar conveyor body 31 from the inside between the two drive gears 33B. The two drive gears 33B are configured to rotate integrally with the first drive shaft 33 and are configured to drive the first bar conveyor body 31 as the first drive shaft 33 rotates.

[0040] As shown in Figures 2 and 3, in this embodiment, the first conveyor 21 is configured to transport materials to the right along the left-right direction of the traveling machine 1. The upstream portion of the first conveyor 21 in the transport direction is located below the cutting device 4. The first conveyor 21 is installed in an upward-sloping position to the right, such that it is located higher towards the downstream side in the transport direction.

[0041] In this embodiment, the second conveyor 22 is a bar conveyor having a plurality of bars extending in the width direction of the second conveyor 22 at predetermined intervals. The second conveyor 22 includes a second bar conveyor body 41 having a plurality of metal bars, a second free-rotating shaft 42 (corresponding to the "second transmission shaft" of the present invention) provided on the upstream side in the conveying direction and configured to rotate freely, and a second drive shaft 43 provided on the downstream side in the conveying direction and transmitting power to the second bar conveyor body 41. The second bar conveyor body 41 is provided across the second free-rotating shaft 42 and the second drive shaft 43.

[0042] In this embodiment, the second conveyor 22 is configured to transport goods to the right along the left-right direction of the traveling machine 1. The upstream end of the first conveyor 21 in the transport direction is located below and upstream of the downstream end of the first conveyor 21 in the transport direction. In other words, the height of the upstream end of the second conveyor 22 in the transport direction is lower than the height of the downstream end of the first conveyor 21 in the transport direction. The second conveyor 22 is installed in an upward-sloping position to the right, so that it is located higher towards the downstream side in the transport direction.

[0043] [Structure of the waste collection roller] As shown in Figures 2 to 5, the waste collection roller 23 is located between the first conveyor 21 and the second conveyor 22 and is a rotating body that can rotate around a rotation axis extending in the width direction of the first conveyor 21 and the second conveyor 22. The waste collection roller 23 is a cylindrical member that extends in the width direction of the first conveyor 21 and the second conveyor 22. Here, the upper surface of the waste collection roller 23 in Figures 3 and 5, which is the surface that can come into contact with the conveyed material transported by the first conveyor 21, is the transport surface of the waste collection roller 23. The waste collection roller 23 rotates in the opposite direction to the rotation direction of the adjacent first drive shaft 33 and the second free shaft 42. In other words, the upper surface, which is the transport surface of the waste collection roller 23, rotates in the opposite direction to the transport direction of the first conveyor 21 and the transport direction of the second conveyor 22.

[0044] The waste collection roller 23 is configured in a cylindrical shape that extends in the width direction of the first conveyor 21 and the second conveyor 22. The waste collection roller 23 is equipped with an anti-slip member 23a having a predetermined thickness on the outer circumferential surface of the cylinder. The material of the anti-slip member 23a may be resin or rubber, but is not limited to these.

[0045] The height of the waste collection roller 23 is set lower than the height of the downstream end of the first conveyor 21 in the conveying direction. Specifically, the height of the uppermost position of the conveying surface of the waste collection roller 23 is set lower than the height of the uppermost position of the conveying surface located in the downstream portion of the first conveyor 21 in the conveying direction.

[0046] The waste collection roller 23 has an anti-slip member 23a positioned where it contacts the first bar conveyor body 31 of the first conveyor 21. With this configuration, even if waste materials such as stems and leaves cut by the cutting device 4 are transported by the first conveyor 21, the transported waste materials are sent below the transport device 5 by the first conveyor 21 and the waste collection roller 23. In this embodiment, the portion of the first bar conveyor body 31 that contacts the anti-slip member 23a is supported from the inside by an inner cylindrical member 33A. With this configuration, the waste materials are firmly held between the first conveyor 21 and the waste collection roller 23 and sent below the transport device 5. The waste materials sent below the transport device 5 are discharged onto the field ground, etc. As a result, it is possible to prevent waste materials such as stems and leaves from being bagged in the flexible container 14.

[0047] Here, carrots C that were not cut into main root and stem / leaves by the cutting device 4 may be transported by the first conveyor 21. At this time, the stems and leaves of the carrots C are sent downwards to the transport device 5 by the first conveyor 21 and the waste collection roller 23. However, as described above, the first conveyor 21 and the waste collection roller 23 are set to be in contact with each other, and the gap is narrow, so the main root of the carrots C cannot pass between the first conveyor 21 and the waste collection roller 23. As a result, the stems and leaves of the carrots C are torn off by the first conveyor 21 and the waste collection roller 23. In other words, the first conveyor 21 and the waste collection roller 23 function as a crop dividing section that separates the carrots C into main root and stem / leaves while they are being transported.

[0048] [Drive system configuration for conveying equipment] In this embodiment, as shown in Figure 5, the first drive shaft 33 is equipped with a first gear 34 that rotates integrally with the first drive shaft 33. Similarly, the second freewheel shaft 42 is equipped with a second gear 44 that rotates integrally with the second freewheel shaft 42, and the waste collection roller 23 is equipped with a third gear 23G that rotates integrally with the waste collection roller 23. A chain 24 is stretched between the first gear 34, the second gear 44, and the third gear 23G. In this embodiment, the first gear 34, the second gear 44, the third gear 23G, and the chain 24 are arranged on the outside of the two side walls 20. Specifically, the first gear 34, the second gear 44, the third gear 23G, and the chain 24 are arranged on the front side of the side wall 20 located in the front-rear direction of the machine body.

[0049] A motor M (see Figure 2) is provided on the downstream side of the conveying device 5 in the conveying direction. Although not explained in detail here, the motor M drives the second drive shaft 43, and the rotation of the second drive shaft 43 drives the second bar conveyor body 41.

[0050] The second freewheel shaft 42 engages with the second bar conveyor body 41 and has a drive gear 42A that rotates integrally with the second freewheel shaft 42. When the second bar conveyor body 41 is driven, the second freewheel shaft 42 rotates, and the second gear 44 rotates together with the second freewheel shaft 42.

[0051] The rotation of the second gear 44 transmits power to the first gear 34 and the third gear 23G via the chain 24. The rotation of the first gear 34 causes the first drive shaft 33 and the drive gear 33B to rotate, driving the first bar conveyor body 31. The rotation of the third gear 23G causes the waste collection roller 23 to rotate.

[0052] In this embodiment, the first gear 34 has 16 teeth, the second gear 44 has 19 teeth, and the third gear 23G has 9 teeth. Since the first gear 34 has fewer teeth than the second gear 44, the transport speed of the first conveyor 21 is greater than that of the second conveyor 22. Also, since the third gear 23G has fewer teeth than the first gear 34, the rotational speed of the waste collection roller 23 is greater than that of the first drive shaft 33. With this configuration, waste materials are transported at a low transport speed by the second conveyor 22, making them easier to collect by the first conveyor 21 and the waste collection roller 23. Furthermore, because the waste collection roller 23 rotates quickly, carrots C with stems and leaves still attached are pulled in forcefully, making it possible to more effectively separate the stems and leaves from the carrots C.

[0053] [Configuration of the speed reduction plate component] In this embodiment, as shown in Figures 2 and 3, a deceleration plate member 51, made of a plate-like member, is provided above the upstream portion of the second conveyor 22 in the conveying direction. The deceleration plate member 51 is supported by a support portion 52 that extends along the longitudinal direction of the traveling machine 1 above the upstream portion of the second conveyor 22 in the conveying direction. The deceleration plate member 51 is supported by the support portion 52 so as to be able to swing around an axis P that extends along the longitudinal direction of the traveling machine 1, that is, along the width direction of the second conveyor 22. Here, in order to prevent backflow of conveyed material, the conveying device 5 may be configured to include a stopper that prevents the deceleration plate member 51 from swinging in the upstream direction of the second conveyor 22 in the conveying direction, that is, to the left in the left-right direction of the traveling machine 1.

[0054] The lower end of the deceleration plate member 51 is positioned at a predetermined distance from the conveying surface of the second conveyor 22. When the carrots C and stems and leaves, which are being conveyed by the second conveyor 22, come into contact with the deceleration plate member 51, their conveying speed is reduced. This makes it easier for the stems and leaves to be collected by the first conveyor 21 and the waste collection roller 23.
