DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled harvesting assisting machine that transports a harvested product by a conveyor while moving or stopping the machine body and stores the harvested product in a storage box manually or automatically.

[0002]

2. Description of the Related Art There has been proposed a self-propelled harvesting auxiliary machine in which a conveyor is provided obliquely on an undercarriage and transports harvested products.

[0003]

In the harvesting operation, when the harvest is excessively accumulated in the temporary storage section of the harvest,
It is necessary to pause the progress of the aircraft. However, when working on the conveyor start end side, more crops are accumulated while moving to the cockpit, so that they may fall from the temporary storage unit and be damaged, thereby lowering the commercial value. In particular, this is remarkable when the conveyor is long.

[0004] In order to solve this problem, it is conceivable to provide a switch box on the lateral side at the conveyor start end side, but if the conveyor is long, it becomes longer and larger. Therefore, it is necessary to reduce the size while improving the operability of the conveyor.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has taken the following technical means. That is, a crop transport device 4 having an operation unit 2 and a conveyor 3 for transporting crops on a chassis having a traveling device 1
And a storage box 5 for storing the crops, and a driving / stopping means capable of driving / stopping the conveyor 3 on the transport start end side of the crop transporting device 4 and at a side intersecting the moving direction. A self-propelled harvesting auxiliary machine.

[0006]

The self-propelled harvesting auxiliary machine may be moved by operating the operation unit 2 to perform automatic harvesting. For example, when a worker pulls out a radish from the field and places it on the conveyor 3, the conveyor 3
Transports the crop toward the transport storage side. Then, the radish discharged from the transport end of the conveyor 2 is stored manually or automatically in a storage box. In such harvesting work,
When it becomes necessary to stop the conveyor 3, the drive is stopped by operating the drive / stop means.

[0007]

According to the present invention, even when working near the conveyor 3, there is no need to return to the operation unit 2, so that the conveyor 3 can be stopped quickly. further,
Since the driving / stopping means is provided on the conveyor start end side of the conveyor 3 and on the side intersecting with the moving direction, even if the driving / stopping means is located in the transverse direction with respect to the traveling direction of the machine, the length in the transverse direction does not increase,
The self-propelled harvesting assist device can be made compact.

[0008]

The conveyor 23 is made of the same material as the conveyor 3 and forms a diagonally rising portion 23a at the transport end side where the thickness T of the conveyor 23 is larger than the thickness t of the conveyor 3, as in the case of the conveyor 3. A chain 35b wrapped around a sprocket 35a removably attached to a shaft 35 rotatably provided on a frame F at an end of a shaft extending the shaft 19 and an obliquely rising portion 4a of the conveyor 3.
Removably attached to.

Therefore, the rigidity of the conveyor 23 is
Since it can be higher than that, the feeding operation to the cutter C described later can be improved, and the cutting accuracy can be increased. Reference numeral 24 denotes a cover for covering the intermediate portion between the conveyor side and the non-transport side of the conveyor 3, and reference numeral 25 denotes a cover for covering the intermediate portion between the conveyor side and the non-transport side of the conveyor 23, which is detachably attached to the frame F. Is provided. Then, on the sides of the covers 24 and 25, a U-shape in a plan view is formed, and a conveyor-side operation body 26 is detachably attached to the front side during work (when the conveyor 3 is positioned in the lateral direction of the machine body). After that, the cover 27 is detachably attached to the frame F.

The conveyor-side operating body 26 has a conveyor on / off switch 28 for turning on / off the conveyor 3, a conveyor up / down switch 29 for adjusting the vertical height of the conveyor 3, and a direction for changing the traveling direction of the machine. A switch 30 is provided. The direction switch 30 is configured to switch the solenoid valve by tilting to one side or the other side in the lateral direction, release the clutch, and slowly turn the traveling direction of the body.

Further, the conveyor on / off switch 28, the conveyor up / down switch 29, and the direction switch 30 are positioned below a virtual line connecting the outer upper edge of the conveyor-side operation body 26 and the upper edge of the rear cover 27. Since the self-propelled harvesting auxiliary machine 6 is transported, the switches 28, 29, and 30 can be prevented from being damaged even when a cover is provided.

Reference numeral 31 denotes a hydraulic motor mounted on the frame F so as to be communicable with a hydraulic pump 33 provided on the chassis 7 through a hydraulic pipe 32. The hydraulic motor 31 has a sprocket through a transmission mechanism such as a chain or a sprocket. 16 and the chain 20 are configured to rotate. A shaft 34 having a shaft center is rotatably provided in a middle portion of the obliquely rising portion 4a and in a direction intersecting (in the embodiment, substantially perpendicular to) the moving direction of the conveyor 3 in plan view. A disk-shaped cutter C located at an intermediate portion between the extension line and the conveyor 3 is attached to the shaft end of the shaft 34.

The sprocket 16 and the sprocket 3 attached to the shaft end of the shaft 34 on the side opposite to the cutter C
6 and a chain 37 is wound around and transmitted.
The valve 38 is turned on or off by turning on or off the switch 16 for turning on the conveyor or the switch 28 for turning on the conveyor.
Hydraulic pump 3 driven by the start of the prime mover
In this configuration, the hydraulic motor 31 is driven or stopped by feeding and stopping the feeding of the hydraulic oil fed from the third hydraulic pump.

The frame F is a vertical frame 3 erected on a chassis 7 on the opposite side of the operation unit 2 so as to be rotatable in the horizontal direction.
9 and a hydraulic piston 41 which slides on a hydraulic cylinder 40 attached to the vertical frame 39, and an intermediate portion of the obliquely rising portion 4a is pivotally mounted. Then, a plurality of holes (not shown) are provided in a positioning plate 42 provided integrally with the base of the vertical frame 39, and the holes are made to correspond to the holes provided in the chassis 7, and the pins 43 are inserted. Thus, the rotating position of the vertical frame 39 can be positioned at any position (in the embodiment, the conveyor 3 can be selected from two positions in the direction substantially orthogonal to the traveling direction of the machine, but three or more positions can be selected).

Reference numeral 44 denotes a diagonally rising portion 2 of the conveyor 23.
This is a box-shaped cover body having an open lower portion that covers the cutter 3a and the cutter C, and is provided with a slope 46 having a wall 45 on the transport start end side of the conveyor 3 formed obliquely downward on the transport start end side. And it is provided in the middle part of the width direction at the upper part of the slope 46 so as to be freely changeable in the vertical and horizontal directions.
A light 4 capable of illuminating an emergency stop switch 48 for stopping the prime mover below the transport unit 23 and the light 47
7 are provided.

A round or square guard 49 is disposed along the outer lower edge of the cover body 44 and at intervals in the lateral direction (at least an interval into which the palm of an operator can enter). Cover 50 for the stay 50 integrally attached to the door 49.
It is attached detachably by a fixture (for example, a bolt). The position of the conveyor 3 can be changed by holding the guard 49, so that the guard 49 can prevent the worker from approaching the cutter side, and can achieve safety.

The cover 44 is operated by removing a mounting fixture which is detachable from the frame F (may be loosened) to operate the conveyor 3 on the rotation fulcrum shaft 51 provided at the rear. Since it is configured to be able to turn in the vertical direction toward the unit side, inspection and cleaning work of the transmission mechanism such as the cutter C and the chain sprocket becomes easy. At this time, since the guard 49 can be rotated integrally with the cover 44, the work is further facilitated.

Further, a cover 44 on the conveyor 3 side
Since the inner covers 52 and 53 are attached to the end portions with the cutter C interposed therebetween, the both covers 52 and 53 prevent lifting of the transported object (radish in the embodiment) and increase the cutting accuracy of the cutter 35. For example, it is possible to prevent non-recovered materials such as leaves from rotating around the cutter C. Reference numeral 54 denotes a light provided on an upper portion of a support post 54a higher than the speed change lever 13 provided on the left side of the operation section 2 in the forward direction of the machine so as to be capable of changing its position in the vertical and horizontal directions. Note that the light 54 is directed toward the conveyor 3, so that the various switches 1
4, 15, 16 and the lever 13 can be illuminated, so that erroneous operation can be prevented even if the visibility becomes poor due to darkness.

Behind the operation section 2 is a storage box 5 provided side by side in the forward direction of the machine body, and is a box for storing the crops sent by the operator from the conveyor 3 to the receiver 55. . Reference numeral 56 denotes an arithmetic control unit (hereinafter referred to as a CPU) of a microcomputer having a memory 57 containing a control program, necessary data, and the like, and performs operations such as arithmetic / logic and comparison operations. An input interface to the CPU 56
There are many pieces of information input through the face 57, but the main ones are the motor stop information from the emergency stop switches 14 and 48, the vertical movement information from the up / down rotation switch 15 and the conveyor up / down switch 29, There are on / off information of the conveyor 3 from the switches 16 and 28, traveling direction change information of the aircraft for changing the traveling direction of the aircraft from the direction switch 30, and the like.

The main drive command signals output from the CPU 56 via the output interface 58 are:
Motor start / stop signal, valve 38 switching signal,
There is a vertical motion signal of the frame F and the like.

Next, the operation will be described. First, when the conveyer 3 is extended laterally and the engine switch 12 is turned on, the up / down turning switch 15 is operated, and the conveyor on / off switch 16 is operated, these information are input via the input interface 57. CP
U56 activates the prime mover to output rotational power, operates the hydraulic piston 41 to position the frame F, that is, the conveyor 3 at a predetermined height, and switches the valve 38 to operate the hydraulic motor.
The data 31 is driven. The rotational power output from the hydraulic motor 31 rotates the conveyors 3, 23 and the cutter 35 via the transmission mechanism.

Next, the operator operates the speed change lever 13 and the power telescopic lever 11 to move the machine body to a predetermined work place to start a harvesting operation. In this operation, first, the operator pulls out the radish, which is the object to be harvested, puts the trunk on the crop placing section 21 of the rotating conveyor 3, and places the leaves on the crop placing section 22 of the conveyor 23. Then, the radish is conveyed in the horizontal direction, then conveyed diagonally upward, and the cutter 35 cuts a predetermined position of the leaf.

Then, the cut leaves fall downward from the transport end of the conveyor 23, but the trunk is discharged from the transport end of the conveyor 3 to the receiver 55. Therefore, the operator grasps the trunk of the radish and holds the storage box. Store in 5. In such a harvesting operation, when the emergency stop switches 14 and 48 are turned on when an abnormality occurs in the cutter 35 or the transmission mechanism, or when there is a risk of causing a danger to the operator, the CPU 56 sets the output interface 58 to. A motor stop signal is output via the motor to stop the motor, so that all the rotating parts of the machine stop.

Since the emergency stop switch 14 is provided on the cover 44 near the cutter 35, an emergency stop can be performed even when the user is near the cutter 35. Since it is provided on the transport start end side, even when working on the end side of the conveyor 3, the rotating parts of the machine body can be stopped quickly, and damage to the machine body and safety of the operator can be enhanced.

Further, the vertical height of the conveyor 3 and the traveling direction of the machine can also be changed on the conveyor start end side of the conveyor 3.
In addition, since the conveyor-side operation body 26 is detachably attached to the rear cover 27, the conveyor-side operation body 26 can be integrally attached and detached by attaching and detaching the rear cover 27, so that the attachment and detachment operation is simplified. Then, the rear cover 27 is covered-2.
Since it is attached to the frame F separately from the frames 4 and 25, attachment / detachment is further simplified. Since the conveyor-side operation body 26 is provided on the forward side of the body of the conveyor 3, it is possible to prevent erroneous operation without interfering with a worker who normally works behind the conveyor 3. In addition, since the conveyor-side operating body 26 does not cover the transport start ends of the two conveyors 3 and 23, the transport of the harvest can be increased without reducing the harvest loaders 21 and 22 of the conveyors 3 and 23.
