Description

[0001]
BACKGROUND OF THE INVENTION
The present invention digs out carrots cultivated in a farm field with a digger installed at the front end of a traveling machine body, feeds it while pulling it up with a continuous pulling and conveying device, and suspends it during conveyance by it. The present invention relates to an improvement on a carrot harvester that cuts the lowered carrot leaf portion with a cutter, drops the root portion onto a conveyor, and collects it in a container that is placed on the fuselage.
[0002]
[Prior art]
In the conventional carrot harvesting machine, as shown in FIG. 1, the left and right sides of the upper surface of the vehicle body a traveled by a pair of crawler-type travel devices b and b are usually used. In addition, a steering device c, a seat d, a prime mover e, and the like are arranged in parallel in the front-rear direction, and sandwiching belts f and f that endlessly rotate in the front-rear direction in plan view are provided on the left and right sides. The pulling / conveying device g configured in parallel with each other is tilted so that the front end side is low and the rear end side is high in a side view, and is mounted via an attachment machine frame provided in the vehicle body a. A digger h is provided on the front end side of g, and the root part is dropped on the lower surface side of the rear end side by cutting the stem part of the carrot that the leaf part is nipped and conveyed by the drawing and conveying device g. A cutter is installed, and the root of the falling carrot is supported below it. A container i for receiving a carrot root discharged from the rear end of the conveyor i is installed on the rear side of the conveyor i. It is configured to mount and collect carrots on it.
[0003]
[Problems to be solved by the invention]
The above-mentioned conventional carrot harvester A sits on a seat d provided on the vehicle body a by the operator and drives the vehicle body a by operating the control device c to drive the carrots grown in the field. , Digging out with a digger h, holding the leaf part with a pulling and conveying device g and feeding it up while pulling up the root part. During that time, the root part is cut by a cutter, and the root part is separated into the container k by the conveyor i. The carrots are harvested automatically and continuously.
[0004]
However, since the container k that receives the root of the harvested carrot is mounted on the mount j that protrudes rearward of the vehicle body a, the container k is in a position that is difficult to see from an operator sitting on the seat d provided on the vehicle body a. Since it is difficult to monitor the amount of ginseng root thrown into k, when carrying out the carrot harvester A and running the harvesting work, an auxiliary worker is placed behind the fuselage to follow and walk, Let this auxiliary worker monitor the state of the carrot root in the container k, and when the container k is full, unload the container k from the gantry j and perform the work of placing a new container k on the gantry j. You must make it.
[0005]
For this reason, the harvesting work requires at least two workers, an operator who operates the machine body and an auxiliary worker who follows, and it is difficult for the operator to work alone.
[0006]
The present invention was made in order to solve the problems occurring in the conventional ginseng harvesting machine. The ginseng is excavated and extracted, and the root of the carrot is separated and collected in a container. It is an object of the present invention to provide a new means by which the harvesting operation can be accurately performed by only one operator for the operation of the aircraft and the monitoring of the loading state of the root portion of the container.
[0007]
[Means for Solving the Problems]
Then, in the present invention, as a means to achieve the above object, against the vehicle body a traveling by the traveling device b · b of the pair of crawlers type right and left, on one side of left and right engine e at the front end A steering device c and a seat d are mounted on the rear end side, and the left and right other sides sandwich the carrot leaf portion excavated by the digger 23 provided on the front end side and convey it to the rear of the drawing. and withdrawal conveying device g to, and mounted a cutter L cutting off the root R of the carrot for transporting, to the intermediate portion of the front and rear of the vehicle a, withdrawal conveying device g provided on the other side of the vehicle body a rear end of the the conveyor i for conveying the root R of the carrot which cut off by the cutter L at the lower surface side, and laterally disposed as the transport direction transverse to the vehicle body a as the direction toward the one side from the other side of the vehicle body a, the transport of the conveyor i the upper end-side surface, prior to in a plan view Deflection guide 31 across the conveying surface, the downstream end of the displaced to the upstream side in the transport direction other side behind the vehicle body a is in the transport direction of the end portion of the other side in front of the vehicle body a said conveyor i Then, the discharge port w for discharging the carrot root R discharged from the conveyance surface by the guide 31 is directed rearward to the position adjacent to the control device c on the rear surface of the vehicle body a. and So設to open, the next-side position of the steering device c behind the outlet w, the open mouth of the top container k to accept collect root R of the carrot is discharged from the discharge port w is release the It is mounted on the mount j so as to be lower than the exit w, so that the operator operating the airframe can monitor the discharge port w of the conveyor i and the open port of the container k simultaneously in the field of view. To raise a carrot harvesting machine.

[0012]
And the conveyor arranged below the rear end side of the pulling and conveying device installed on the other side of the vehicle body crosses the vehicle body from side to side so that its conveying direction is directed from the other side of the vehicle body to one side. And a guide that crosses the upper surface of the conveyor obliquely with respect to the conveying direction is provided on the end side in the conveying direction of the conveyor, whereby the rear end side of the drawing and conveying device on the other side of the vehicle body The discharge port of the conveyor that conveys the root part of the carrot from below to the side of the vehicle body discharges the root part of the carrot toward the lateral position of the aforementioned steering device at the terminal end side in the transport direction of the conveyor. Configure.
[0013]
Further, the gantry for placing the container for collecting the roots of the carrots discharged from the discharge port of the conveyor is a pulling and conveying device for the control device disposed at the rear end of one side of the vehicle body. On the side next to the control side, it is installed in a position parallel to the left and right of the control device so that the opening on the upper surface side of the container placed individually is located below the discharge port of the conveyor.
[0014]
Thus, an operator operating the aircraft can simultaneously monitor the introduction state of the carrot root with respect to the container placed on the gantry parallel to the side while operating the control device. To.
