Description

The present invention is a multi-row root vegetable harvester that simultaneously digs multiple rows of root vegetables cultivated along a plurality of rows of ridges, and foliar clogging that prevents transport clogging of foliage cut from root vegetables before digging. The present invention relates to a prevention device and a multi-row root vegetable harvester equipped with the prevention device.

Conventionally, when harvesting root vegetables such as beets, a root vegetable harvesting machine has been used. When root vegetables are harvested using such a root vegetable harvester, the root vegetables are cut off after the foliage is cut from the root vegetables and conveyed to the next step by a digging conveyor. In this case, the foliage is repelled outside the digging opening of the digging conveyor.

On the other hand, in recent years, a multi-row type root crop harvesting machine that simultaneously digs a plurality of rows of root vegetables cultivated along a plurality of rows of ridges has been put into practical use. In such a multi-row type root crop harvester, since the digging mouth is formed so as to extend over the plurality of rows of ridges, the foliage stays between the ridge rows in this digging mouth, which is normal. There are problems such as being unable to dig.

Therefore, in order to deal with such a trouble, a foreign matter removing mechanism between beat ridge rows has been proposed (Patent Document 1). The present invention relates to a rotary drive cleaner that is supported in front of an excavation opening provided corresponding to a plurality of beet rows and removes beet foliage and soil between the beet rows laterally, and this rotary drive cleaner. It is equipped with a pair of left and right disc-shaped coulters rotatably supported toward the ground between the beet ridge rows, and the foliage between the beet ridge rows is divided into left and right beet ridge rows by the mutual inclined surfaces of the left and right coulters. It is pushed up to the top of the and is removed by a subsequent cleaner by swinging it out of the row of beet ridges.

Japanese Patent No. 5186609

However, the foreign matter removing mechanism between beat ridges described in Patent Document 1 needs to be provided with a rotation drive mechanism that rotates in the lateral direction, which causes a problem of high cost. Further, the above-mentioned rotary drive cleaner has a drawback that its removal performance is extremely low because it is necessary to shake off the foliage in either direction with respect to the row of ridges to remove it. Further, for example, even if the rotation driving force is increased, the root vegetables to be originally harvested are thrown away, and the harvest rate is significantly reduced.

On the other hand, if no measures are taken to remove the foliage, a large amount of foliage will accumulate between the rows of ridges at the digging mouth, and the harvester will push the accumulated material and proceed, resulting in spillage. There is a problem that normal digging cannot be done. In addition, since the amount of foliage taken into the harvester along with the root vegetables is increased, there is also a problem that problems in transportation tend to occur.

The present invention has been made to solve the above problems, in a multi-row root vegetable harvester that digs multiple rows of root vegetables cultivated along multiple rows of ridges at the same time, And it is a cheap structure, and it can prevent the jamming of the foliage conveyance efficiently by using the existing driving force, and can carry out the harvesting work smoothly.

Hereinafter, each configuration will be described.

As shown in FIGS. 3 and 4, the digging blade 11 is for digging the root vegetables 300 buried in the soil, and is formed in a plate shape. The digging blade 11 is inclined upward from the front (advancing direction) to the rear (retracting direction), and the tip is installed at a height that allows it to enter the soil (ridge) of the field 400. In the present embodiment, in order to enable the root vegetables 300 of the two rows of ridges 200 to be dug, each of the two left and right digging openings 16 formed at the front lower end of the digging conveyor 12 according to the intervals of the ridges 200. They are installed one by one. The shape of the digging blade 11 is not limited to a plate shape, and may be appropriately selected from comb-like shapes and the like.

The digging conveyor 12 is a so-called belt conveyor that conveys the root vegetables 300 dug by the digging blade 11. The digging conveyor 12 in the present embodiment is formed such that the left-right width is wider than the left-right width formed by each ridge 200 in accordance with the interval between the two rows of ridges 200. The digging conveyor 12 is configured to be inclined upward from the front to the rear, and is rotationally driven to convey the root vegetables 300 upward.

The auxiliary conveyor 13 is a belt conveyor for sandwiching the excavated root vegetables 300 together with the excavation conveyor 12 and assisting the upward conveyance.

As shown in FIGS. 5 and 6, the transport conveyor 14 is a belt conveyor including a selection roller 15 among the belt conveyors that transport the dug root vegetables 300. As shown in FIG. 2, the transport conveyor 14 in the present embodiment is installed on the rear side of the digging conveyor 12 and the auxiliary conveyor 13 in a direction orthogonal to the transport direction (to transport in the left-right direction). Since the transport conveyor 14 is rotationally driven, it has rotary shafts at both ends. The rotary shaft on the side of discharging the foliage among the rotary shafts is a drive shaft 141 for driving the conveyor 14.

As shown in FIG. 7, the sorting roller 15 is a roller that sorts the root vegetables 300 transported by the transport conveyor 14 and the foliage transported together with the root vegetables 300. It is installed so as to incline in the intersecting width direction. There is a lower gap than the root vegetables 300 between the selection roller 15 and the conveyor 14, so that the root vegetables 300 can be laterally transferred along the rotating selection roller 15 and discharged from the transfer outlet 17. In addition, the foliage is conveyed along the conveyor 14 through the gap and discharged from the end to the outside of the machine. The transfer outlet 17 includes a rear end side of the inclined selection roller 15 and a side portion of the transport conveyor 14 in the flowing direction of the root vegetables 300 transferred by the selection roller 15.

A spill prevention plate 18 that prevents the root vegetables 300 from spilling out of the harvester is provided behind the selection roller 15 along the transfer direction. The lower end of the spill prevention plate 18 projects below the selection roller 15.

The foliage clogging prevention device 1 is for preventing clogging by scraping off the foliage accumulated on a conveyor that conveys the root vegetables 300 mounted on the multi-ridge type root vegetable harvesting machine 10, and is mainly used to remove the foliage. It comprises a scraping rotor 2 for scraping, and is rotatably provided on the rotary shafts 131 and 141 of the conveyor. In addition, in the present invention, the foliage is cut from root vegetables before digging, and includes foreign matters such as pebbles and earth and sand fixed to the foliage.

As shown in FIGS. 3 to 6, the scraping rotator 2 is made of a disc-shaped metal-based or resin-based elastic material, and is made of polyurethane in this embodiment. In the scraping rotor 2, a plurality of scraping claws 21 for scraping off the foliage are radially extended from the outer circumference and are inclined with respect to the normal direction. A fitting hole 22 into which the rotary shafts 131 and 141 of the conveyor are fitted is formed in the central portion of the scraping rotator 2. The scraping rotator 2 in the present embodiment is provided near the digging opening 16 and near the transfer outlet 17, respectively. In the following, the installation position of the scraping rotary member 2 will be described together with the factors that clog the foliage in the vicinity of the digging opening 16 and in the vicinity of the transfer outlet 17.

The digging opening 16 formed by the digging conveyor 12 and the auxiliary conveyor 13 is provided with a plurality of digging blades 11 for digging the root vegetables 300 as described above according to the intervals of the ridges 200. In the multi-ridge root vegetable harvester 10, the rooting device 11 pulls the root vegetables 300 from each ridge 200 by being pulled by a tractor or the like.

At this time, the foliage that has been cut from the root vegetables 300 and remains in the field 400 before digging is repelled in the laterally outward direction by the digging blade 11, as shown in FIG. On the other hand, the foliage between the digging openings 16 and 16 is not repelled to the outside, but is blocked by the digging conveyor 12 and stays there. If the harvesting operation is continued with the staying, the multi-row root vegetable harvesting machine 10 pushes the staying matter to run, and normal digging cannot be performed due to spillage.

Therefore, in the present embodiment, as shown in FIGS. 3 and 4, the scraping rotator 2 rotates at the outer end of the rotary shaft 131 of the auxiliary conveyor 13 at the digging opening 16 between the auxiliary conveyors 13, 13. It is mounted so that it can scrape the foliage accumulated in the vicinity of the digging opening 16 into the digging conveyor 12.

Specifically, the scraping rotator 2 rotates integrally with the rotary shaft 131 by fitting the fitting hole 22 into the outer end portion of the rotary shaft 131 of the auxiliary conveyor 13 inside each digging opening 16. It has been fixed to. At this time, the tip of the scraping claw 21 is arranged at a height slightly higher than the height of the farm 400 where it comes into contact with the farm 400, and the foliage remaining in the farm 400 can be scraped into the excavation conveyor 12. You can do it. In the present embodiment, the foliage that is attached to the right end of the rotary shaft 131 of the left auxiliary conveyor 13 and the left end of the rotary shaft 131 of the right auxiliary conveyor 13 and that stays in the center of each digging opening 16 is The digging conveyor 12 is scraped. The rotary shaft 131 on which the scraping rotor 2 is installed is a drive shaft that drives the auxiliary conveyor 13 to rotate as long as the rotary shaft 131 can transmit the driving force of the auxiliary conveyor 13 to the scraping rotor 2. Alternatively, it may be a driven shaft that operates in accordance with the driving rotation of the auxiliary conveyor 13.

Further, although the scraping rotary member 2 in the present embodiment is attached to the rotary shaft 131 of each auxiliary conveyor 13, it is not limited to this configuration, and either the rotary shaft on the left or right depending on the required scraping amount. It may be attached to 131, and two or more may be attached to each rotating shaft 131.

Next, in the vicinity of the transfer outlet 17, the foliage that could not be selected by the selection roller 15 is transferred to the transfer outlet 17 together with the root vegetables 300. At this time, the foliage that could not be sorted remains in the vicinity of the overhanging portion of the spill prevention plate 18, as shown in FIG. If this state is left as it is, the selection rollers 15 are lifted by the accumulated foliage and the gap with the transport conveyor 14 is widened, and the root vegetables 300 to be sorted pass through the gap with the transport conveyor 14. In the present embodiment, since the scraping rotor 2 provided near the digging opening 16 scrapes the foliage accumulated between the digging openings 16 into the digging conveyor 12, the foliage conveyed with the root vegetables 300. Is large, the stems and leaves tend to be clogged near the transfer outlet 17.

Therefore, in the present embodiment, the scraping rotator 2 is rotatably attached to the outer end portion of the drive shaft 141 of the transfer conveyor 14 provided near the transfer outlet 17, and stays in the vicinity of the transfer outlet 17. It is designed to scrape off the foliage that is used.

Specifically, the scraping rotator 2 fits and fixes the fitting hole 22 in the outer end portion of the drive shaft 141 of the transport conveyor 14 on the transfer outlet 17 side. At this time, the tip of the scraping claw 21 is arranged so as to be located in the vicinity of the transfer outlet 17 where the foliage is accumulated. In the present embodiment, two scraping rotators 2 are juxtaposed at a lower position rearward of the sorting roller 15, and rotate in a direction opposite to the inclination direction of the scraping claw 21 together with the drive shaft 141 of the transport conveyor 14. By doing so, the foliage is scraped out and discharged to the rear of the conveyor 14.

Next, the operation of the stem/leaf clogging prevention device 1 of the present embodiment and the multi-row type root crop harvester 10 including the same will be described.

In order to mount the foliage prevention device 1 on the multi-ridge type root crop harvester 10, the scraping rotator 2 is attached to the rotary shaft 131 of the auxiliary conveyor 13 or the drive shaft 141 of the transport conveyor 14, respectively. As described above, the scraping rotator 2 is simply attached to the rotary shafts 131 and 141 of the conveyor of the multi-row type root vegetable harvester 10, and therefore can be mounted easily and at low cost.

Next, the stems and leaves are cut from the root vegetables 300 before the root vegetables 300 are dug by the multi-ridge root vegetables harvesting machine 10. The cut foliage is left in the field 400.

The multi-ridge root vegetable harvester 10 is arranged so as to straddle a plurality of rows of ridges 200, in this embodiment two rows of ridges 200, and is pulled along the ridges 200 by a tractor or the like. The digging blade 11 provided in the digging opening 16 digs the root vegetables 300 in the soil of the ridge 200. At this time, the soil and the leaves are repelled by the digging blade 11 to the outside of the digging conveyor 12 on the left and right sides. The foliage that has not been bounced is conveyed by the digging conveyor 12 and the auxiliary conveyor 13 together with the root vegetables 300.

The foliage between the ridges 200 cannot be repelled by the digging blade 11 and remains between the digging openings 16. The scraping rotator 2 in the foliage clogging prevention device 1 rotates together with the rotary shaft 131 of the auxiliary conveyor 13 near the digging opening 16. In this way, it is possible to rotate the scraping rotator 2 together with the rotational driving of the auxiliary conveyor 13, and it is possible to effectively utilize the existing driving force. At this time, since the scraping claw 21 has its tip installed at a height which is slightly higher than the height of the farm 400 to be installed in the farm 400, by rotating it, the foliage between the rows of rows is scraped and excavated. It is placed on the conveyor 12. This prevents foliage from clogging between the digging openings 16 and enables normal digging work.

Next, the root vegetables 300 and the foliage after being transported by the digging conveyor 12 are transported by the transportation conveyor 14. On the transport conveyor 14, the sorting roller 15 transports the transported root vegetables 300 in the lateral direction, and the foliage is passed through the gap between the transport conveyor 14 and sorted. The foliage that has not been sorted out here is transferred to the transfer outlet 17 together with the root vegetables 300, and a part of the foliage is stuck between the transfer conveyor 14 and the spill prevention plate 18. At this time, the scraping rotator 2 attached to the outer end of the drive shaft 141 of the transfer conveyor 14 provided near the transfer outlet 17 rotates to scrape the foliage accumulated in the vicinity of the transfer outlet 17. It is taken and discharged to the rear of the transfer conveyor 14. This prevents the selection roller 15 from floating due to the foliage clogging in the vicinity of the transfer outlet 17, thereby preventing the root vegetables 300 from passing through the gap between the conveyor 14 and being discharged to the outside of the harvester. Further, since it is possible to rotate the scraping rotator 2 together with the rotation drive of the transport conveyor 14, the foliage clogging prevention device 1 does not need to be separately provided with a rotation drive unit.

Then, the root vegetables 300 delivered from the transfer outlet 17 are transferred to the top of the multi-row root vegetable harvester 10 by the transfer elevator 19 and stored in the storage tank 20. As described above, it becomes possible to smoothly perform the harvesting work by using the multi-row root vegetable harvester 10, and the harvest rate of the root vegetables 300 can be improved.

According to the foliage clogging prevention device 1 of the present embodiment and the multi-row root vegetable harvester 10 including the same as described above, the following effects can be obtained.
1. By utilizing the driving force of the conveyor in the multi-row type root crop harvesting machine 10, it is possible to efficiently prevent clogging of foliage.
2. It is possible to prevent the clogging of the foliage between the digging openings 16 which is caused by the multi-ridge type by the foliage clogging prevention device 1 having a simple and inexpensive structure.
3. It is possible to prevent the foliage from clogging near the transfer outlet 17, and prevent the root vegetables 300 from passing through the gap between the conveyor 14 and the selection roller 15 and being discharged to the outside of the machine. In particular, it is possible to prevent the clogging of the foliage, which increases due to the rake of the foliage between the digging openings 16.
4. By preventing foliage from accumulating near the digging opening 16 and near the transfer outlet 17 and clogging each conveyor, etc., normal digging work is maintained, and smooth harvesting work is performed to prevent the root vegetables 300 from growing. The harvest rate can be improved.

It should be noted that the foliage clogging prevention device and the multi-row type root vegetable harvester equipped with the same according to the present invention are not limited to the above-described embodiments, and can be appropriately modified.

For example, in the above-described embodiment, the foliage clogging prevention device 1 is used for the two-row multi-row root vegetable harvester 10 in which the scraping rotor 2 is attached to the central portion of the digging opening 16.
