Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves harvesting sugar cane by harvesting it in the field, removing the crown head and trash, and cutting and cutting the wisteria stems to a predetermined length. This article concerns a sugarcane harvesting machine designed to

[Successful technology]

When harvesting sugarcane, in other countries, the leaves and tops of the tops are burned with the foundation stalks standing on the field before harvesting, but in Japan, there are two factors: ■ There is a lot of rain during the harvest season, and ■ The land readjustment of the field. We try to harvest with the tops and leaves still attached for reasons such as the fact that they are not fully formed and the desire to use the tops and leaves as organic fertilizer.

As such a harvester, for example, as described in Japanese Unexamined Patent Publication No. 157146/1989 proposed by the applicant, the top of the crown is cut off from the wisteria stem, the base of the stem is harvested, and the wisteria stem is harvested. While being transported to the rear of the aircraft in a vertical position, some leaves are shed and the whole stem is discharged and stored. There is also a type of harvester in which the stalks are cut to a predetermined length after defoliating, cut and stored; however, with this type of harvester, the stalks are removed from the stalks that have been cut and cut. Since no measures have been taken, there have been problems such as insufficient removal of trash, resulting in a reduction in yield, or the need to re-sort trash at the sugar manufacturing stage. [Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned circumstances, and in particular, it is possible to separate trash from shredded wisteria stems, improve screening, and reduce the yield at the sugar manufacturing stage. It is an object of the present invention to provide a sugar cane harvesting machine which not only improves the quality of harvesting but also facilitates the storage and transport of cuttings, cuttings, and sorted stalks.

[Means for solving the problem] In order to achieve this object, the present invention provides a crop lifter provided at the front part of a traveling vehicle body, a tapper for cutting off the top of the tree stem raised by the crop lifter, A base cutter that cuts off the base of the wisteria stem from which the crown head has been removed, a pair of upper and lower supply rollers that feed the root part of the wisteria stem that has been cut from the base of the wisteria stem by the base cutter to the rear of the machine, and the machine body. A pair of chain-equipped defoliating rolls are installed vertically opposite each other across the path of the wisteria stalks moving backwards, and rotate backwards, and the removed stems are cut to a predetermined size. In a sugarcane harvesting machine equipped with a pair of cutters, a cutting roll, and a conveyor that conveys the cut and cut stalks diagonally upward to the rear of the machine,
A plate-shaped buffer member whose upper end is pivotally supported and whose lower end is swingable is provided at the conveyance terminal end of the conveyor, a trash guide plate provided behind the lower end of the buffer member, and a trash guide plate provided below the buffer member. , a loading platform capable of vertically rotating on which storage boxes or bags with open tops are placed or suspended, and a blower provided below the conveyor and blowing sorting air toward the buffer member. It is characterized by this.

The lifters 5, 5 are provided with their upper parts pivotally supported by the chassis 1 so as to be rotatable back and forth, and a hydraulic cylinder 6 is installed between the lower part and the chassis 1, and the hydraulic cylinder 6 can be expanded and contracted. The front and rear inclination angle of the crop lifter 5 can be adjusted by rotating around the pivot point. Furthermore, when there is no need to use the crop lifter 5, such as when traveling on the road or when turning the aircraft, the crop lifter itself can be adjusted to be positioned upward by a hydraulic cylinder 6a provided on the back of the crop lift Yuki body. It is now possible to do so. Furthermore, shoes 7, 7, which also serve as dividers, are attached to the lower end of the crop lifter 5, so that the shoe 7, 7 can be adjusted up and down together with the crop lifter 5. Above the passage formed between the crop lifters 5, a tapper 8 is installed at the front of the chassis 1 to cut off the top of the sugar cane that is lifted up by the crop lifter 5 and introduced into the passage. It is provided so as to protrude forward from the frame la.

This tapper 8 can be adjusted up and down according to the height of the sugar cane to cut off unnecessary crown heads. Further, a push-down village 9 is disposed in the horizontal direction between the crop lifters 5, 5, so that the wisteria stems introduced into the passage are pushed down in a forward-inclined manner as the vehicle platform 1 moves forward. A base cutter 10 consisting of a disk-shaped rotary blade for cutting the base of wisteria stems is provided at the lower front part of the chassis 1, and above the front part, the cut stems are cut by the base cutter 10'. ,
A scraping roll 11 is provided at the base of the machine to feed it toward the rear of the fuselage in a vertically long position with the trunk at the top.

Further, behind the base cutter 10, a pair of upper and lower feed rolls 12, 12, defoliation rolls 13, 13, a cutter,
Cutting rolls 14, 14 are provided in order, and are configured to rotate rearward while facing each other. The feed roll 12 is provided with a feed blade on the roll circumferential surface to feed the bear stems later, and the defoliation roll 13 has a chain of a certain length on the circumferential surface of the roll at one end and the other end as a free end. A chain rotating in the centrifugal direction by the rotation of the roll removes the trash attached to the periphery of the pedicle.
Further, the cutting roll 14 has a pair of rolls or a rotating shaft, and has horizontally long cutting blades protruding from the circumferential surface of the rotating shaft so that they face each other during rotation. When they match, the wisteria stem and trash are cut to a predetermined length.

Behind the cutting and cutting roll 14, an endless conveyor 15 is provided which conveys the cutting and cutting bear stalks rearward and obliquely upward.

Below the conveyance end of this conveyor 15, a container 16 (or a suspended bag) with an open top surface is placed on a loading platform 17 attached to a frame lb provided so as to hang down from the rear end of the vehicle platform 1. is being sent to war. As shown in FIG. 1, the loading platform 17 has its base part supported by a frame 1M, and a large number of rollers 17a, 17a, . . .
... is provided, and the container 16 can be loaded and unloaded by being rotated up and down about a pivot point by a hydraulic cylinder 18 provided between the loading platform 17 and the frame lb. Further, a trash guide plate 19 is provided above the rear of the container 16, and a plate-shaped buffer member 20 is provided above the container 16 at the end of conveyance of the conveyor 15, with its upper end supported and its lower end free end. This buffer section 201 is provided to swing.
Accordingly, the sorting air is blown up from the blower 21 onto the cuttings, cut stems, and trash discharged from the conveyor 15. Incidentally, instead of the loading platform 17 and the container 16, a carry-out conveyor 22 is provided which is connected to the conveyor 15 and carries out the chopped and sorted bear stems to the side of the machine. The vehicle may be stored in the cargo bed of a companion vehicle.

When harvesting sugarcane planted in a field, the sugarcane harvester configured as described above first adjusts the inclination angle of the crop lifter 6 by expanding and contracting the hydraulic cylinder 6 according to the lodging condition of the sugarcane, and also adjusts the inclination angle of the crop lifter 6 by expanding and contracting the hydraulic cylinder 6. The ground height of the harvester 7 and the height of the tapper 8 are adjusted by a hydraulic cylinder 6a to run the harvester and perform harvesting work.

Then, the sugarcane is divided by the crop lifter 5 and the shoe 7, and the long canes that have fallen down by the crop lifter 5 and have extended to the adjacent ridge are pulled over and introduced into the passage between the crop lifters 5 and 5, and unnecessary The top of the treetop is cut off with a tapper 8 and left in the field. The stem from which the top head has been removed is pushed down as the machine moves forward, and the village 9 bends the stem into a forward leaning position, and the base of the stem is cut off by the base cutter 0'. The cut competitive stems are raked by a raking roll 11 with the root trunk at the beginning, and then passed to a feeding roll 12.
, 12, and was sent to the rear. Then, large trash is removed by a scrapping roll 13, and cut into a predetermined length by a cutting/cutting roll 14. The cut stems and trash are brought onto the conveyor 5 and conveyed backward and diagonally upward, and are discharged from the end of the conveyance, collide with the two buffer members and fall. At this falling position, the sorting air from the blower 21 is blown up towards the buffer member 2, so the trash with a light specific gravity is discharged to the rear of the aircraft along the trash guide plate 19, and the trash with a heavy specific gravity The stems are either dropped into a container 16 (or suspended bag) or stacked onto an output conveyor 22. When loading and unloading the container 16, the loading platform 17 is moved back and forth (up and down) by the hydraulic cylinder 8, and since the loading platform 17 is provided with rollers 7a, handling is simple and speedy work is possible. I can do it. Also, when the harvester travels on the road or turns on a headland, the hydraulic cylinders 6 and 6a pull the crop lifter 5 and shoe 7 toward the vehicle body 1, thereby reducing the turning radius and making tight turns. Headland can be reduced.

〔Effect of the invention〕

As explained above, the sugar cane harvester according to the present invention has
A plate-shaped buffer member and a trash guide plate provided at the end of the conveyor and a storage box or bag provided below the end of the conveyor with an open top can be stacked or suspended and rotated in the vertical direction. a loading platform and a blower installed below the conveyor and blowing sorting air toward the buffer member;
Since the swallow stems are installed with a holder, the swallow stems are cut to a predetermined length, cut, and then the wisteria stems and trash are collided with a buffer member, and the trash mixed in the swallow stems is removed by a sorting wind, creating a container that can be easily moved. In particular, the wisteria stems can be stored in a suspended bag, and the wisteria stems can be harvested by cutting and cutting them to a predetermined length, and using a simple wind selection mechanism to remove trash without damaging the wisteria stems. The harvested wisteria stalks can be subjected to the sugar refining stage without re-sorting or reconditioning the trash.

In addition, loading and unloading the containers onto the harvesting machine is extremely easy, and efficiency in the harvesting work is achieved.
