Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a harvesting machine, which is mainly used for harvesting multi-cultivated tubers such as garlic balls and konnyaku balls. Concerning what you do.

(Conventional technology) Conventionally, when harvesting mulched tubers such as garlic balls and konnyaku balls, it is necessary to remove the soil that has been pressed down on the film, and to cut off the stems and leaves that protrude above the film. This requires a collection operation for removing the film, and a harvesting operation for harvesting the tuber crop, but each of these operations is generally performed separately and in stages.

(Problem that the invention aims to solve) In conventional harvesting operations, each task needs to be done separately and in stages, which requires a lot of effort and time, and is extremely inefficient. There's a problem.

Therefore, the present invention was devised in view of the above points, and an object of the present invention is to enable efficient harvesting work by performing each work simultaneously.

Next, brackets 27 are integrally erected at the rear upper portions of the side frames 3 on both sides, and between the upper portions of the brackets 27 on both sides, a winding roller 28 for winding the film F as a film collecting means is installed. It is rotatably supported via a rotating shaft 29 integrated with this,
One end of this rotating shaft 29 protrudes into one end of the second chain case 30, and the winding roller 28 is driven to rotate in synchronization with the advancing speed of the harvester. In addition, the second chain case 3
0 is fixed to the bracket 2, and the other end of the output shaft 6 of the transmission is projected into the other end of the second chain case 30. An endless chain 33 is suspended between a sprocket 31 fixed to the rotary shaft 29 and a sprocket 32 fixed to the protruding end of the rotary shaft 29.

Further, a tip 34 as an excavation body is protruded between the front ends of the side frames 3 on both sides, and a carry-in portion of a conveyor 35 is connected to the rear end of the tip 34, which is inclined rearward. A container pedestal 36 fixed to the rear end portions of the side frames 3 on both sides is disposed at the unloading portion of the conveyor 35. The conveyor 35 includes a driven shaft 3 which is rotatably horizontally suspended between the side frames 3 on both sides at a position close to the rear end of the tip 34.
7, a drive shaft 38 rotatably suspended horizontally at the rear upper part of the side frames 3 on both sides, and a large number of horizontal rods 39 rotating between the endless chains facing each other between the drive shaft 38 and the driven shaft 37. An endless body 40 configured by freely arranging shafts in parallel is connected to a sprocket 41 and a driven roller 42.
It is configured to be suspended so that it can rotate freely through. Further, one end of the drive shaft 38 of the conveyor 35 is projected from one side frame 3, and a V
A V-belt 45 is suspended between the pulley 43 and the V-pulley 44 of the output shaft 6. Further, an arm 4 of a ground plate 46 is provided at the middle lower part of the side frame 3 on both sides.

The rotation of the drive shaft 15 rotates the respective rotation shafts 21 via the respective bevel gears 16 and 22, thereby rotating the rotary cutter 23 and the blades 24, and the rotation of the rotation shaft 29 rotates the winding roller 28. The endless body 40 of the conveyor 35 is rotated in the direction of the arrow in FIG.

Then, when the harvesting machine is pulled by a tractor in the field, each rotary cutter 23 rotates forward along the film F covering the field, and the tubers protruding onto the film F are cut by each rotary cutter 23. The foliage of the harvest is cut on the film F, and the cut foliage is discharged outward by the blade 24, and the foliage is cut on the film F.
The weight covering soil for pressing down the film F placed on both sides of the field is removed outwardly by the earth removal bodies 26 on both sides, and the film F becomes separable from the field. At the same time, the take-up roller 28 rotates, and the film F is sequentially wound up while being separated upward from the field surface, and the tip 34 is attached to the harvested tuber from which the stems and leaves have been cut. The tuber harvest is carried forward from the tip 34 onto the conveyor 35, and transported backwards by the endless body 40 while shaking off the soil, and finally placed on the container pedestal 36. It is carried into container A.

In this way, the tuber crop is harvested continuously.

Next, in the embodiment described above, the film F is wound up by the winding roller 28 as the film collecting means, but the present invention is not limited to this. It may also be possible to collect it while being pulled by a holder and release it sequentially to the rear. Further, in the above case, the film F may remain spread, or the spread film may be released as a string. Further, when recovering the film F, a coulter may be provided at a predetermined position and the film F may be divided into predetermined widths by the coulter.

[Effect of idea]

According to the present invention, the multi-cultivated tuber crop can be easily harvested by simultaneously collecting the film, and at this time, the stems and leaves of the tuber crop that protrude on the film are removed using a rotating cutter. is cut on the film by
This film is separated upward from the field and collected by the film collecting means at the rear upper part of the machine frame, so although the film collecting work and the harvesting work of the tuber crop are carried out at the same time, there is no mutual interaction between them. The work can be carried out smoothly without interfering with each other, and since the film collecting means is installed at the rear upper part of the machine frame, the film can be collected while removing foliage. Harvesting work can be carried out with high efficiency.
