Abstract

PROBLEM TO BE SOLVED: To provide a root crop harvester having a conveyor with a structure which hardly causes failures or the like due to conveyed sand since biting sand causes detachment of a chain or damage to component members of a transmission system due to overload when the sand around crops is conveyed with the crops to a subsequent process by a pullout conveyor, and the sand is caught in a gap between a sprocket and the chain of each conveyor.SOLUTION: A conveyer (87) includes a pair of driving rotating bodies (79, 79) by which a conveying passage of crops is sandwiched, driven rotating bodies (81, 81), and transmission endless belts (82, 82). In a root crop harvester, one driving output shaft (79a) where the driving rotating bodies (79, 79) are mounted is arranged on a downstream side in a conveyance direction rather than a conveyance beginning end part of the conveyor (87).

Description

  The present invention relates to a harvester that harvests root vegetables such as carrots.

  The root vegetable harvesting machines described in the prior patent documents 1 and 2 are configured to pull out a crop from a field by a pulling and conveying device and convey it to the rear, and collect the crop with a flexible container bag provided at a conveying terminal portion of the sorting and conveying device. is there.

  The pulling and conveying device is for pulling out the foliage of a crop to be vegetated in the field, and when the foliage is short, it is necessary to bring the starting end close to the field scene. At this time, in many cases, the pulling and conveying device sandwiches the foliage and at the same time sandwiches the earth and sand around the crop together, and this earth and sand is transported to the subsequent process together with the crop. In order to prevent a failure or the like in a later process, it is necessary to remove the earth and sand adhering to each part of the machine body, and there is a problem that the time and labor consumed by the worker are increased.

  If the transported earth and sand are left unattended, if they enter the gap between the sprockets and the chain of each transport device, for example, the chain will fall off due to the biting of the sand and the components of the transmission system will be damaged due to overload. There is a problem. As a result, there arises a problem that the crop harvesting operation is interrupted for a long time and a problem that extra time and labor are required for repair.

  In addition, it is possible to prevent damage to major members by providing a safety device such as a shear pin against damage to the components of the transmission system due to this overload, but replacement of the safety device is necessary Since the harvesting operation is interrupted accordingly, the work efficiency is lowered.

  If the transmission part of each conveyor is configured with only a belt, the problem of damage to the components is unlikely to occur.However, since the earth and sand are transported together with the crop in the belt transport, the earth and sand hides the wounds etc. of the crop and even crops that are not suitable for harvesting. There is a problem that the accuracy of sorting will be reduced, and the sediment will fall into the flexible container bag, the amount of crops will be reduced accordingly, the number of operations to lower and install the flexible container bag will increase, and the work efficiency will decrease. Arise.
