A harvesting transporting device for hanging and transporting, and a transporting device for positioning which is brought into contact with the upper end of the root of the root vegetable suspended by the harvesting transporting device as the harvesting transporting device pulls up, are provided. An apparatus has been developed in which a blade body for cutting the foliage of root vegetables from the apparatus is provided on the lower side of the transfer device for positioning. In the conventional root crop harvesting machine, as shown in FIGS. 7 and 8, the right and left transport chains 11
A plurality of rollers 12 rotating around the longitudinal axis of the chain are arranged side by side over the entire length of the chain, and are independently biased by separate springs 13 in the foliage clamping action direction. The foliage portion F of the root vegetable C attached and suspended by the harvesting transport device 14 is
It was constituted so that it might be pinched by.

[0003]

However, it has a complicated structure in which an extremely large number of rollers juxtaposed over the entire length of the chain are slidably mounted on the transport chain, and each of the multiple rollers is biased by a separate spring. Therefore, the manufacturing cost of the positioning device is increased, the soil is easily deposited and accumulated on the positioning device, and the maintenance is likely to be troublesome. This is improved from the viewpoint of reducing the manufacturing cost of the positioning device and facilitating the maintenance. There was room for SUMMARY OF THE INVENTION An object of the present invention is to improve the position-determining transfer device so that it is advantageous in terms of manufacturing cost and easy to maintain, and to maintain a good transfer function.

[0004]

SUMMARY OF THE INVENTION The present invention is characterized in that a harvesting transporting device for sandwiching and pulling a foliage of a root vegetable planted in a field and pulling it obliquely upward at the rear of the machine to transport it in a hanging manner is provided. Providing a position setting transfer device that abuts on the upper end of the root crop root suspended by the harvesting transfer device along with the lifting by the harvesting transfer device, a blade body for cutting the foliage of the root vegetables from the harvest transfer device, In the root crop harvesting machine provided on the lower side of the positioning device, in order to form the positioning device, the left and right holding rods for weakly holding the root of the foliage so as to be able to slide close to each other can be freely separated and separated. The present invention is provided with a locking and conveying device which is provided in a state of being approached and biased, and which acts on a root portion of a root vegetable which is in sliding contact with the holding rod.

[0005]

According to the characteristic constitution of the present invention, the stems and leaves are clamped while the stems and leaves are slidably contacted by clamping rods such as left and right round bars or band plates which are biased toward each other. Compared to a structure in which a very large number of rollers arranged side by side are urged by separate springs, the configuration of the positioning device can be greatly simplified, and the manufacturing cost of the positioning device can be sufficiently reduced. In addition, it is possible to sufficiently suppress the adhesion and accumulation of soil on the positioning device, and to facilitate the maintenance of the positioning device. In addition, since the root portion of the root vegetable that comes into sliding contact with the holding rod is forcibly transported by the locking and transporting device, the posture of the root vegetable caused by sliding contact with the holding rod is reliably suppressed, and a good transport function is achieved. Can be maintained.

[0006]

As a result, it is possible to manufacture the positioning device inexpensively and to easily maintain it, and to maintain a good transport function. The root crop harvesting machine is excellent in manufacturing cost, maintenance and transport function. Can now be provided.

The portion F is raised by the left and right weeding tools 3a and the raising device 3b, and is smoothly transferred to the harvesting transport device 1.
And a leaf cutting device 8 configured to cut off the soil on both sides of the root vegetable C with the cutting blade 4 to smoothly pull out the root vegetable C, and to cut the foliage F of the root vegetable C from the transporting device 1 for harvesting.
Is provided at the rear of the harvesting conveyance device 1.

In order to form the leaf cutting device 8, a positioning transporting device that contacts the upper end of the root vegetable C suspended by the harvesting transporting device 1 as the harvesting transporting device 1 raises the root. 8a and a cutting and conveying device 8b comprising a pair of left and right drivable holding and conveying belts, etc., for holding and receiving the foliage F from the harvesting and conveying device 1 above the holding position of the positioning and conveying device 8a. A pair of left and right driving rotatable blades 8c for cutting the foliage F of the root vegetable C conveyed by the cutting transport device 8b at the root are provided on the lower side of the positioning transport device 8a, and act on the root of the root vegetable C. The locking transport device 8d to be engaged is provided below the positioning transport device 8a.

A collecting unit 9 for collecting the root vegetables C from the leaf cutting device 8 is provided behind the harvesting conveying device 1 and below the leaf cutting and conveying device 8. The container is dropped into the lower container 9a, and the large-diameter container is stored at the root vegetable receiving position at the rear corner of the fuselage.
