Japanese Patent Laying-Open No. 2003-92912 (paragraph number [0013] and FIGS. 1 and 2)

If the agricultural products are packed in a container and handled as described above, the separated agricultural products can be handled in units of containers, which is effective in improving the workability thereafter. However, in the crop harvesting machine having the above conventional structure, there is no problem in moving the empty box of the container onto the container stand. However, after the container is filled with the crop, the container weight is increased due to a significant increase in the container weight. There is a problem that a great deal of labor is required for operations such as moving from a container stand to a side deck or moving further on the deck.
In addition, when the agricultural products are almost fully packed in the container and then forcibly moved to the container receiving table side, unless the driving of the conveying device that conveys the agricultural products to the container table where the container existed is stopped, There is a problem that a large number of crops spill on the container table, are damaged, and are scattered to the outside of the machine below.
For this reason, conventionally, once the crop is full in the container, the drive of the transfer device is stopped once, and then the full container is moved to the container receiving table side, and then the empty container is replenished on the container table, and then the transfer device The procedure of resuming driving was taken.
According to such a procedure, even when the harvesting operation by the crop harvester is continued, the harvested crop is temporarily retained on the transport device, and the supply of the crop to the container table is stopped. The container can be moved and refilled.
However, according to the above procedure, if the driving stop time of the conveying device is prolonged for a while, there is a risk that the crops that have stayed on the conveying device may fall off, so a series of operations are required to be performed quickly and neatly. It is easy to cause an operation error and an operation delay of a serious operator.

  The pair of right and left weeding devices 11 scoop up the carrot leaf b vegetated in the field by the scoop arm 11c, and the leaf b from the scoop arm 11c protrudes forward from the weeding case 11a. By lifting up the front side of the weed case 11a with the raising claws 11b, the carrot leaves b to be harvested are separated from the carrot leaves b to be harvested and are caused to be raised. It is connected to the front end side of the main frame 13a via the frame of the transport device 14 whose front end is connected and supported.

  The right and left soil unraveling blades 15 pierce the soil on the side of the carrot to be harvested, and loosen the soil so that the carrot body a can easily escape from the soil when the transport device 14 pulls out the carrot body a from the field. Go.

  The conveyance device 14 drives and rotates a pair of left and right endless conveyance belts 14a in a posture of a rear upward slope in which the conveyance start end portion is located near the rear side of the pulling device 11, and the conveyance end side is located at a higher level on the rear side of the machine body. The pair of endless conveyor belts 14a are provided and freely inherited and pinched from the weeding carrot leaf part b from the weeding device 11 and conveyed upward in the rearward direction of the machine body. As a result, the transport device 14 pulls out the carrot a to be harvested from the field by the pair of endless transport belts 14a, and continues to lift and transport the leaf part as it is in a suspended posture.

  The leaf removing device 20 includes a pair of left and right positioning endless chains 22 whose start ends are located near the rear side of a portion located on the transport start end side from the transport end position of the pair of endless transport belts 14a of the transport device 14.

Then, as the conveying device 14 conveys the carrot having undergone hair root cutting, the vicinity of the head of the carrot body enters the lower side of the positioning endless chain 22, and thereafter, the endless conveying belt 14a of the conveying device 14 continues. When the transport end side lifts and transports the carrot, the carrot body is in a positioning state in which the top of the head contacts the positioning endless chain 22. The carrot leaf portion in this positioning state is cut and conveyed by the cutting and conveying endless belt 27 and the leaf portion conveying endless chain 24 from the conveying device 14, and is nipped and conveyed backward. Then, the vicinity of the carrot head in the leaf part of the transported carrot is supplied to the rotary blade 23 and cut, and the carrot body falls at this cutting position. Even after the cutting, the cutting and conveying endless belt 27 and the leaf portion conveying endless chain 24 are configured to convey the leaf portion further rearward and drop it onto the discharge chute 25.
Thereby, the leaf part removing device 20 cuts the carrot leaf part after the hair root has been removed by the rotary blade 23 near the head of the carrot body, and cuts and conveys the carrot body without the hair root and the leaf. The endless belt 27 is dropped onto the belt conveyor 40, and the cut leaves are dropped onto the field by the discharge chute 25 behind the machine body.

[Crop Collection Department]
The crop collection unit A includes a crop transport device 4 for changing the direction of the carrot body a as a crop harvested by the harvesting unit 10 and supplying it to the container transfer device, and the carrot body from the crop transport device 4. a container transfer device 5 for collecting and sending out a to the container C, a container receiving table 6 for storing the container C filled with crops on the machine, and an empty container C in the container transfer device 5 Auxiliary seat 7 provided so that an auxiliary worker for performing a predetermined operation such as supplying a container or taking out a container C filled with crops can perform the operation while sitting on the seat. It consists of and.

The crop conveying device 4 receives the carrot falling from the leaf portion removing device 20 located at the rear end of the harvesting unit 10 and conveys it in the rear direction of the machine body, and above the end side of the belt conveyor 40. For selection processing of the carrot fed from the belt conveyor 40 and the feed roller 41 which is positioned so as to be able to be driven obliquely and changes the direction of carrot feeding on the belt conveyor 40 from the rear side to the right side of the body. It is comprised with the roller conveyor 48 which conveys body sideways.
As shown in FIGS . 4 and 8 , the roller conveyor 48 has a large number of rod-shaped rollers 48a arranged so as to be slightly higher toward the lower side in the feed direction (right lateral direction). It is a slat type sorting conveyor that is arranged and rotated and is configured to drop waste carrots, garbage, soil, etc. while forcibly transporting.
On the upper side of the drive system of the roller conveyor 48, the roller conveyor 48 is driven by a clutch that can be manually and intermittently operated by operating a clutch lever 42 that is an example of an artificial operation tool. An intermittent mechanism 43 is interposed.

[Container transfer device]
As shown in FIGS. 2 and 4, the container transfer device 5 includes a container base 50 for mounting the container C so as to collect the carrot body a from the roller conveyor 48 into the container C, and the container base. A container supply unit 55 for storing an empty container C supplied to the container 50, and a container take-out unit 56 (container for taking out and placing a full container C filled with crops in the container table 50) Part of the storage table 6 also serves as a storage base).
The upper side path C1 for supplying the empty container C to the container base 50 is a path from the front side of the machine body to the rear side, and is a lower side for taking out the full container C from the container base 50. The side path C2 is a path from the position of the container base 50 toward the right side of the machine body. That is, the upper-side radial path C1 and the lower-side path C2 are provided in directions intersecting each other as shown in FIG. 8, and the container base 50 is located at the intersection.

As shown in FIGS. 5 to 7, the container base 50 includes a guide body 51 that constitutes a reference height position as a mounting surface 50F for mounting the container C on the container base 50, and With respect to the mounting surface 50F having the reference height by the guide body 51, the container C is positioned from a position slightly lower than the mounting surface 50F to a position higher than the height of the mounting surface 50F having the reference height. It is possible to provide an elevating support base 52 capable of changing the attitude and hold the container C at a height position different from the mounting surface 50F having the reference height in accordance with the attitude change of the elevating support base 52. and it is configured there as (see FIG. 4及 beauty Figure 11).

As shown in FIG. 4 to FIG. 6, the guide body 51 that sets the reference height position so as to constitute the mounting surface 50 </ b> F on the container base 50 takes out the full container C from the container base 50. It is composed of a large number of spherical guide rollers 51a pivotally supported around a horizontal axis X1 in a direction orthogonal to the lower side path C2.
Thus, when each guide roller 51a is formed in a spherical shape and pivotally supported around the horizontal axis X1 in a direction orthogonal to the lower path C2, the container C on the guide roller 51a is supported. When pulling out the container along the lower path C2, the container C, which is full of crops and increases in weight, can be pulled out easily by rotating the guide roller 51a around the horizontal axis X1. it can.
When the empty container C is pulled out from the container supply unit 55 on the front side of the machine body of the container base 50 along the upper path C1 onto the container base 50, the pulling direction is a direction along the horizontal axis X1. Therefore, the individual guide rollers 51a do not rotate around the horizontal axis X1. However, since the shape of each guide roller 51a is spherical, the guide surface 51f at the upper end of each guide roller 51a is a quadratic curved surface that curves upward.
For this reason, the bottom surface side of the container C is guided by the upwardly curved secondary curved surface, smoothly rides on the guide roller 51a, and moves while sliding.

As shown in FIG. 7, among the guide rollers 51a, the guide roller 51a corresponding to the upper side portion in the container transport direction is more horizontally oriented than the guide roller 51a located at the lower side portion thereof. A slight height difference 5h1 and 5h2 is provided so that the height position is high when.
Similarly, also in each guide roller 61a of the container accommodating portion 6 to be described later, the guide roller 61a on the side closer to the container base 50 corresponding to the upper side location in the container conveying direction is a guide located on the lower side location. A slight height difference 6h1, 6h2 is provided so as to be higher than the roller 61a when the machine body is in a horizontal position. Also, in the relationship between the container table 50 side and the container storage table 6 side, the former is positioned higher than the latter.

  8 and 11 indicates a stopper for limiting the empty container C supplied on the container base 50 from being easily displaced due to the influence of the vibration of the airframe. The biasing force by the spring is set to such an extent that the container base 50 on which the container C exists is lightly pressed and biased toward the upper side in the transport direction. Therefore, if the container C which has become full is pulled slightly toward the lower side of the path, the container C moves over the stopper 57 and moves to the container receiving table 6 side.

As shown in FIGS. 5 and 8, on the container base 50, the spherical guide rollers 51a are provided between the left and right rows along the lower path C2, that is, the rows of the left and right guide rollers 51a. An elevating support base 52 configured in an L shape in a side view is disposed with a horizontally oriented plate-like body 52a positioned therebetween and a vertically oriented frame body 52b perpendicular thereto.
As shown in FIG. 11, the elevating support base 52 is integrated with a swinging support shaft 53 in the front-rear direction that is pivotally supported by the support base portion on the terminal end side of the roller conveyor 48 at a position above the container base 50. It is provided so as to be swingable around the axis of the swing support shaft 53, and an empty container C is obliquely loaded so that the carrot body a from the crop transporting device 4 can be received and recovered with little drop impact. It is configured as follows.
That is, an operating rod 52c is continuously provided at the bottom of the lifting support base 52. The operating rod 52c is manually operated in the lifting direction to change the posture to the oblique posture shown in the figure, and this state is internally provided. A known damper device 54 that urges in the extending direction by the force of the spring is always urged upward.

The damper device 54 is connected to a bracket 53a formed integrally with the swing support shaft 53 of the lifting support base 52 via a connection pin. The position of the shaft core P2 of the connecting pin can be moved to both sides with respect to a line segment Y connecting the shaft core of the swing support shaft 53 and the shaft core of the connecting pin 54a of the damper device 54. It is comprised so that the raising / lowering support stand 52 can be stably maintained at two positions where the posture is changed to the oblique posture shown in FIG. 11 (a) and the mounting posture shown in FIG. 11 (b). Has been.
That is, the axis P2 of the connecting pin is a position beyond the dead point, with a line segment Y connecting the axis of the swing support shaft 53 and the axis of the connecting pin 54a of the damper device 54 being a dead point line. When the container C is empty as shown in FIG. 11 (a), the lifting support base 52 is lifted up to the upper limit by the lifting biasing force of the damper device 54.
In this state, when the collection of the crop into the container C proceeds, the damper is so arranged that the lifting support base 52 is slowly lowered against the urging force of the damper device 54 as the weight of the filled crop increases. It is comprised so that the resistance by 54 springs may act. When the filling of the container C further proceeds, the lifting support 52 is placed on the container placement surface 50F of the container stand 50. At this time, the axis P2 exceeds the dead point line Y. It is located in the state of FIG.
In this state, since the axis P2 is maintained in the state of FIG. 11B beyond the dead point line Y, this state is maintained even if the container C is removed from the lifting support base 52. Become.
In order to bring the lifting support base 52 into the oblique posture shown in FIG. 11 (a) again, the operating rod 52c continuously provided on the lower surface side of the plate-like body 52a of the lifting support base 52 is gripped, and the axis of the connecting pin The operation is performed so that P2 crosses the dead point line Y in the reverse direction, and the lifting support base 52 is rotated around the swing support shaft 53.

As shown in FIG. 13, the container C placed on the container table 50 is pushed out to the container receiving table 6 side on the side of the container table 50 and below the roller conveyor 48. As a possible delivery mechanism, a hydraulically operated telescopic cylinder 44 is provided.
The telescopic cylinder 44 operates in response to an operation command of the control device that detects the disconnection operation of the clutch lever 42 in the same manner as the drive interrupt mechanism 43 constituted by a clutch that performs on / off operation of the roller conveyor 48. And is automatically extended by a predetermined amount (appropriate amount for sending out the container C on the container table 50 to the container receiving table 6 side) by an artificial clutch disengagement operation by the clutch lever 42, It is configured to retire immediately.
Accordingly, when the clutch lever 42 is turned off and the crop conveying device 4 is turned off, the container C filled with the crop is sent out from the container base 50 to the container storage base 6 side in this state. When the auxiliary worker refills the container base 50 with the empty container C and turns on the clutch lever 42, the supply of agricultural products to the empty container C is resumed.
The drive interrupting mechanism 43 is not limited to the clutch, and may be configured by a switch that performs the driving of the crop conveying device 4 by an independent electric motor and independently switches this on and off. What is necessary is just to be able to intermittently drive the crop conveyance device 4 at an arbitrary time point with the operation.

A space for mounting an empty container C is provided on the airframe frame 3 on the front side of the airframe of the container base 50, and this space supplies a container supply section for supplying the empty container C to the container base 50. 55, and the container transport path from this part to the container table 50 is the upper path C1.
A box-shaped transmission cover 49 covering the power transmission structure to the traveling transmission case 9 and the harvesting section 10 is provided on the left side of the container supply section 55 and in front of the roller conveyor 48 from the roller conveyor 48. The upper part of the transmission cover 49 is a spare empty container place D.

As shown in FIG. 12, this spare empty container storage space D is formed in a space surrounded by the lower peripheral wall portion 58 erected on the periphery of the transmission portion cover 49 and on the peripheral portion thereof. And a pair of left and right guide grooves 59.
The guide groove 59 is provided with a pulling operation tool 70 so as to be guided by the guide groove 59, and the pulling operation tool 70 pulls the handle portion 71, thereby pulling the handle portion at the innermost portion. A pressing piece 72 provided integrally with 71 is configured to push the empty container C in the space surrounded by the peripheral wall portion 58 from behind and to draw it closer to the container stand 50.
Inside the peripheral wall portion 58, the three empty containers C are arranged in the state where the longitudinal direction is directed in the front-rear direction at the innermost portion and the longitudinal direction is directed in the left-right direction on the front side (aircraft rear side). Placed and accommodated. With such an arrangement, the space with the narrowest width in the left-right direction between the harvesting unit 10 and the driver's seat 2a can be effectively used as a space for disposing the empty container C, and the front side Then, the longitudinal direction is directed in the left-right direction to shorten the front-rear direction distance.
Further, in configuring the empty container storage space D, the rear end portion of the transmission unit cover 49 is transported by the crop conveyor roller conveyor 48 as shown in FIGS. 3, 8, and 12. It is provided in an overhanging state so as to extend to the upper side of the surface, and is devised so that the area of the empty container storage area can be expanded in the front-rear direction.
Further, the peripheral wall portion 58 is removed from the peripheral wall portion 58 of the empty container storage space D near the container stand 50, and the longitudinal direction of the empty container C is set to the left-right direction as described above. In addition to being convenient to place the container, the empty container C is taken out from the empty container storage place D and is also convenient for the work when the container supply unit 55 is placed in the standby position.

  In the container transfer device 5 as described above, the following operations are performed. In this harvester, an auxiliary worker is attached in addition to a driving worker who controls the aircraft. The auxiliary worker basically sits on the auxiliary seat 7 at the rear of the traveling machine body and visually sorts the non-defective carrots a placed and conveyed by the roller conveyor 48, while the conveyor table of the container transfer device 5 is used. The container C which is stored in the container C loaded in the container 50 is moved to the rear of the container container 6 or moved from the container supply unit 55 in front of the conveyor table 50 to the conveyor table 50 side. A container moving operation is performed such that the hand reaches from the rear through the roller conveyor 48 and the empty container C loaded in the empty container storage D is transferred to the container supply unit 55.

[Container stand]
A container storage base 6 having a length extending from the container transfer device 5 to the lateral side of the riding-type operation unit 2 is shown in FIG. Around the front-rear axis P1, it is arranged so as to be able to switch between a horizontal overhanging posture continuous with the container transfer device 5 and a retracted posture folded upward.
The container receiving table 6 is composed of an upper-side receiving table portion 61 provided with a forcible driving means 60 for transferring the container C toward the front side of the machine body, and a lower-side receiving table portion 62 provided with no forcible driving means 60. Has been.

As shown in FIG. 7 and FIG. 8, the upper-side accommodation base portion 61 has a spherical guide roller 61 a as a guide body similar to the guide body 51 in the container transfer device 5, and a container of the container transfer device 5. It is provided so as to constitute a container mounting surface 61F positioned slightly lower than the mounting surface 50F, and in the same way as the container transfer device 5, so that it can be easily transported to the right side of the aircraft along the lower path C2, It is configured to be rotatable around a horizontal axis X2 in a direction intersecting the lower side path C2.
As shown in FIGS. 8 and 9, in the upper-side container 61, at each position between the outermost guide roller 61a and the innermost guide roller 61a among the spherical guide rollers 61a, A pair of left and right drive chains 60a for forcibly moving the container C from the rear side to the front side of the machine body is provided, and a pressing body 60b is installed over the left and right drive chains 60a, and the drive chain 60a is wound around the drive chain 60a. A drive sprocket 60c for driving is provided.
The forcible drive means 60 is configured by the drive chain 60a, the pressing body 60b, the drive sprocket 60c, and the electric motor M that transmits power to the drive sprocket 60c.

As described above, the upper-side container 61 has a function as a container take-out portion 56 for taking out and placing a full container C filled with crops in the container stand 50. Yes, it has the same mounting area as that of the container table 50 and can be mounted for one container.
In addition to the above function as the container take-out portion 56, the upper-side storage base portion 61 transports the container C toward the lower-side storage base portion 62 side that follows (the lower side in the transport direction). Since the transfer function is achieved by the combination of the guide roller 61a and the forced driving means 60, the container C sent out from the container table 50 needs to be reloaded on the transfer device. Instead, they can be forcibly conveyed and accommodated in a direction different from the delivery direction.

The forcible driving means 60 in the upper-side container part 61 is driven by a first sensor S1 that detects that the container C has been sent from the container table 50 to a predetermined location of the upper-side container part 61, and a lower side that will be described later. It is controlled by the detection operation of the second sensor S2 and the third sensor S3 provided in the accommodating table portion 62.
That is, the first sensor S1 detects the presence of the container C, and one of the second sensor S2 and the third sensor S3, or both the second sensor S2 and the third sensor S3 detect the presence of the container C. Otherwise, the drive chain 60a is forcibly driven by the half circumference and is present in the upper-side accommodation base 61 by a pressing operation by one of the two pressing bodies 60b attached to the periphery of the drive chain 60a. The container C is configured to be fed toward the lower container portion 62, and when the sensors S1, S2, S3 are in other detection states, the drive chain 60a is configured not to be driven. ing.

As shown in FIGS. 3, 8 , and 10, the lower-side container part 62 is a deck frame having a predetermined accommodation area for accommodating the container C fed from the upper-side container part 61. A guide wheel 64 is provided at 63 at predetermined intervals, and a non-driving guide configured by a rod-shaped fixed guide 65 that fits into a circumferential groove 64 a of each guide wheel 64 is provided.
In other words, the deck frame 63 is configured as a common frame with the frame of the upper-side container 61 and is disposed on the lower side of the upper-side container 61 in the container driving direction. Two rows of left and right guide wheels 64 along the moving direction are pivotally supported around the horizontal axis X3 intersecting the container moving direction.

  As shown in FIG. 10, the guide wheel 64 has a circumferential groove 64a in which the rod-shaped fixed guide 65 can be fitted from the radially outer side to the outer peripheral portion. In the inserted state, it is rotatably supported by the horizontal shaft 66, and is arranged at intervals of about 1/2 to 1/5 of the feed direction length of the container C to be transported.

The fixed guide 65 is made of a metal bar having a diameter slightly smaller than the depth of the circumferential groove 64a of the guide wheel 64, and guides the bottom surface side of the container C at a position away from the guide wheel 64. It is configured so that guidance by sliding with the container C can be performed.
The combined use of the rod-shaped fixed guide 65 and the guide wheel 64 as described above is advantageous in that the number of the guide wheels 64 used can be greatly reduced compared to the case where only the guide wheels 64 are used, and the fixed guide 65 is used alone. This is because, in addition to the guide only by sliding friction, the guide wheel 64 can be used together with the rolling friction of the guide wheel 64 and can be transported more lightly.
Note that the diameter of the rod-shaped fixed guide 65 should be set in consideration of not only the relationship with the depth of the circumferential groove 64a of the guide wheel 64 but also the relationship between the arrangement interval of the guide wheels 64 and the material strength. Yes, the point is that the number of guide wheels used is small, the feed resistance does not increase so much, and the difference between the depth of the circumferential groove 64a of the guide wheel 64 and the bar diameter is not so great as to cause rattling of the container. Anything can be used.

[Another embodiment]
[1] In the above embodiment, spherical rollers are exemplified as the guide rollers 51a and 61a. However, the present invention is not limited to this, and the rotation shaft core is not limited to this, but is related to the width in the rotation axis direction and the diameter around the rotation shaft core. The shape can be changed as appropriate, such as a shape whose length in the direction is larger than the length in the radial direction, or conversely, a shape whose length in the radial direction is larger than the length in the rotation axis direction. So long as it can be guided in a direction along the axis of rotation or in a crossing direction.
[2] As the guide member 51, a spherical guide roller 51a as described above, not limited to a 61a, For example, the quadric surface curvature is, the direction of the curvature along the axial direction, which It is not limited to the one having the same curvature in the direction intersecting the two, but may have a shape having different vertical and horizontal curvature ratios.
[3] In the above-described embodiment, when configuring the mounting surfaces 50F and 61F configured by the guide rollers 51a and 61a of the container base 50 and the upper-side accommodation base portion 61, the guide rollers 51a and 61a having the same diameter Although the structure in which the height of the shaft cores of the horizontal shaft cores X1 and X2 is shown is not limited to this, for example, the diameter of the guide rollers 51a and 61a on the upper side in the container transport direction is changed to the guide rollers 51a and 61a on the lower side. The height of the mounting surfaces 50F and 61F may be changed by making it larger than the diameter.
[4] The delivery mechanism for delivering the container C from the container base 50 is not limited to the push operation with the telescopic cylinder 44 as shown in the embodiment, but, for example, in conjunction with the drive turn-off operation of the drive interrupt mechanism 43, You may comprise so that the whole container base 50 may incline and slide.
