BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention and will be described below.

The present embodiment is a bean harvester for removing beans 2 grown on a stalk 1 vegetated on a ridge 10 of a field without removing the stalk 1 from the ridge 10.

In this embodiment, green soybeans 2 contained in pods as beans for performing bean stripping operations are targeted, and are configured as green soybean harvesters. In addition, the bean stripping structure according to the present embodiment is not limited to the green soybean harvester, and the design can be appropriately changed as long as the configuration is a use form that can exhibit the characteristics of the present embodiment.

Hereinafter, each component of the embodiment will be described in detail.

As shown in FIG. 1, the moving base 3 is constituted by a metal frame comprising a front portion 3A and a rear portion 3B. The front portion 3A has a transparent portion covering the front and left and right side surfaces thereof. The cover body 11 with 11a is provided, and the front part 3
A ceiling plate 23 is provided on the upper surface of A.

Further, an opening is provided in a portion to be in front of the cover body 11, and this opening has a height and width capable of passing the stem 1 with green soybeans 2, and the stem 1 with green soybeans 2 is provided. As a stalk introduction portion 11b.

The moving base 3 has wheels on its left and right sides.
The wheel 12 is provided rotatably by the operation of an appropriate drive source 13 disposed above the front portion 3A. Therefore, the movable base 3 according to the present embodiment is self-propelled with the drive source 13 by itself, and has a basic structure that is indispensable for running as an agricultural work vehicle. In this embodiment, the movable base 3 is a self-propelled type.
For example, it may be a towing type that is used by being connected to an agricultural work vehicle such as a tractor.

The movable base 3 is provided with operating portions 17 having the same structure at two positions, that is, at the front end portion of the front portion 3A and at the base end portion of the rear portion 3B. The operation unit 17 can operate a traveling means such as a starter for starting the drive source 13, an accelerator (throttle), a change lever for switching the traveling direction of the moving base 3, and a brake lever, and also a bean scraper described later. The operation such as operating or stopping the blowers 4 and 5 and the blower 18 can be performed. The operating portion 17 disposed at the base end portion of the rear portion 3B is used to change the direction of the moving base 3 at a time other than when the green soybeans 2 are removed, for example, when the moving base 3 is straddled on the ridge 10. On the other hand, the operating section 17 disposed at the tip of the front section 3A is used when the moving base 3 is moved straight ahead mainly at the time of removing the green soybeans 2 and the operator is in front of the moving base 3. It can be used when moving the green soybeans 2 while checking whether or not the stripping operation is being performed well.

Therefore, the operator can freely select the operation unit 17 each time and can move the moving base 3 alone and satisfactorily.

The moving base 3 is provided with a sled-shaped grounding plate 14, 15 for removing the green soybeans 2 from the stem 1 so that the stem 1 does not float below the front end 3A of the front part 3A. It is juxtaposed. Between the grounding plates 14 and 15, the stem 1 of green soybean 2
Is set in the stalk-introducing gap.

It is desirable that the rear ends of the ground plates 14 and 15 be located at least rearward of the front end positions of the bean strippers 4 and 5. This is because green soybeans 2 are beans stripped bodies 4,5
In the initial stage in which the green soybeans 2 are stripped off and the green soybeans 2 are peeled off, the force that tends to pull out the stem 1 from the ground works best, so that in order to prevent this, the rear ends of the grounding plates 14 and 15 have at least This is because it is necessary to be located at a position rearward from the tip positions of 4,5.

It is to be noted that a holding plate may be provided upright inside the grounding plates 14 and 15 to hold the stem 1, or a pair of endless belts may be provided on the left and right instead of the holding plates. A configuration in which the belt is sandwiched between opposed belts may be employed.

A pair of bean strippers 4 and 5 are provided in the front portion 3A of the movable base 3.

The bean strippers 4 and 5 are provided with radially flexible plates 4b and 5b at positions facing metal shafts 4a and 5a, respectively.
The shaft rods 4a and 5a are provided with tapered portions 4c 'and 5c' at their ends.
The flexible plates 4b and 5b slightly protrude from the grooves formed in the cover members 4c and 5c.

The bean strippers 4 and 5 are inclined in the front part 3A with the rear side higher than the forward direction with a predetermined space therebetween.
It is provided rotatably via. The direction of rotation of the strippers 4 and 5 is the direction of the arrow shown in FIG.

The process of stripping green soybeans 2 in the bean strippers 4 and 5 will now be described. If the stem 1 is disposed between the rotated bean strippers 4 and 5, the two bean strippers 4 and 5 will be described. The stripping process of stripping the stalk 1 from the stalk 1 is performed such that the ends of the flexible plates 4b and 5b squeeze the green soybean 2 upward.

The moving body 3 is provided with a carrier 6.

The transporting body 6 is composed of a pair of rotating shafts 6a rotating via the driving source 13 and a pair of transport belts 6b spanned between the rotating shafts 6a. The bean stripping bodies 4 and 5 are set in the front portion 3A of the base 3.
At a rear (lower) position in parallel with each other. Therefore, the green soybeans 2 received by the transport body 6 are transported to the rear portion 3B side.

The transport body 6 has a front end side (lower end side).
A gap (passing portion 7) is formed at the center.

The passage portion 7 is for allowing the stem 1 from which the green soybeans 2 have been removed to be movable to the rear of the carrier 6 in the same manner as the grounding plates 14 and 15 described above.

More specifically, the passage portion 7
Is provided at the center position of the transport body 6 at a position below (rearward position of) the stripping processing section 8 between the bean stripping bodies 4 and 5. By being provided behind the stripping bodies 4 and 5, the bean stripping bodies 4 and 5 are provided.
This is because it is necessary to pass the stem 1 to the position of the carrier 6 because the green soybeans 2 falling from the position 5 can be reliably received.

The passing portion 7 is provided with a closing member 9 for preventing the peeled beans 2 from passing therethrough.

The closing body 9 is composed of a pair of brush members 9 having appropriate flexibility enough to allow the passage of the stem 1. It is configured to protrude inward to face inward.
Therefore, when the stem 1 passes between the bean strippers 4 and 5, the closing body 9 changes the shape according to the shape of the stem 1 to allow passage of only the stem 1, and thus the stem 1 Even if 1 is passing through the passage section 7, the green soybeans 2 stripped by the bean strippers 4 and 5 are prevented from being discharged from the passage section 7 of the stem 1 to the outside of the moving base 3 as much as possible. Will be. That is, if the closing body 9 is made of a hard material, the stem 1 passing through the closing body 9 is sandwiched between the closing body 9 and a state like a stick, and a gap is generated between the members forming the closing body 9. Therefore, the green soybeans 2 are discharged from the gap to the outside of the moving base 3.
With the configuration of the present embodiment, such a problem does not occur. The closing member 9 can exhibit the characteristics of the present embodiment, for example, by adopting a brush member 9 having appropriate flexibility as in the present embodiment, or by using a resin member such as rubber. Any material can be used as appropriate.

The same material as that of the closing body 9 is also provided in the stem introduction part 11b. In addition, rotating blades 19 are provided at the distal end portions of the left and right transport belts 6b of the transport body 6, respectively.
Is provided.

The rotating blades 19 are disposed in a receiving container 20 provided at a position below the leading end of the carrier 6, and are provided with the driving source 13 described above.
It is provided rotatably via the.

The rotating blades 19 are configured to scrape the green soybeans 2 and leaf scraps which have been removed by the bean strippers 4 and 5 and fall into the receiving container 20 and send them to the carrier 6.

In this embodiment, in order to remove the green soybeans 2 from the lower side of the stem 1, the ends of the bean strippers 4 and 5 are arranged to a position near the ground (ridges 10). 6
Can not be arranged to a position near the tip of the bean strippers 4 and 5 because of its structure.
Receiving container 20 with little installation space near the tip of 5
So that the green soybeans 2 and leaf dust received in the receiving container 20 are scraped up by the rotating blades 9 and sent to the carrier 6.

From the above configuration, the front portion 3A of the movable base 3
Is formed in a case shape in which substantially the entire surface is closed, so that the green soybeans 2 stripped by the bean strippers 4 and 5 is prevented from being discharged (dropped) to the outside of the movable base 3 as much as possible. Become.

A sorter 21 is provided in the rear part 3B of the movable base 3 near the end position of the carrier 6.

The sorting body 21 is formed by forming a suitable metal member into a plate shape, and is disposed at a position spaced from the end of the carrier 6 by a predetermined distance L. When the stem 1 that has fallen off the ground or has been broken by the action of the bean strippers 4 and 5 is conveyed by the carrier 6, the stem 1 is separated through the sorting body 21 and placed below the gap L.
This is for sending out to the rear of the sorting body 21 without dropping to the sorting body 21.

A blower 18 (blower) is provided in the rear part 3B of the moving base 3 and at a position below the end of the carrier 6.

The blower 18 is configured such that the wind blows at a predetermined wind pressure from the lower side toward the rear (the direction a in FIG. 1) from below to the gap between the end of the carrier 6 and the sorting body 21.
Even if the wind pressure is large enough to pass through the gap between the end of the carrier 6 and the sorting body 21, the light-weight leaf dust and dust blown away by the wind do not pass through the gap. Behind the moving base 3 (outside) in the same manner as the stem 1
While the relatively heavy green soybeans 2 that are not blown off by the wind are configured to fall into the harvest box 22.

Therefore, only the green soybeans 2 transported by the transporter 6 fall into the harvest box 22, and are reliably sorted out from other leaf chips, stems 1, and the like.

Hereinafter, a method for harvesting green soybeans using the bean harvester according to the present embodiment will be described. First, when the moving base 3 is moved forward while rotating the bean strippers 4 and 5 with the moving base 3 straddling the ridges 10 of the field, the stem 1 is introduced between the left and right grounding plates 14 and 15, and the moving base 3 is left as it is. When the movable body 3 is advanced, the pair of bean strippers 4 and 5 is moved to a position where the movable base 3 is gradually removed from the stem 1 and the green soybeans 2 are all removed from the stem 1. At this time, the stem 1 is guided by the passage portion 7 and passes through the moving base 3.

Subsequently, the removed green soybeans 2 and some of the leaf scraps are sent upward by the carrier 6, and are appropriately sorted to collect only the green soybeans 2 in the harvest box 22.

Since the present embodiment is constructed as described above, the transporting body 6 for transporting the green soybeans 2 stripped by the bean stripping bodies 4 and 5 is provided behind the bean stripping bodies 4 and 5, which is different from the conventional machine. Thus, it is possible to reliably prevent the stripped green soybeans 2 from being received by the carrier 6 and to fall (discharge) to the outside of the moving substrate, and to transport the stripped green soybeans 2 by the carrier 6. At the same time, the passing portion 7 provided on the transport body 6
The step of harvesting green soybeans 2 by passing the stalk 1 to the outside of the moving base 3 is efficiently performed without waste in a series of operations along with the movement of the moving base 3.
The green soybeans 2 can be quickly and reliably peeled off without pulling out the stem 1 from the ground, and the efficiency of the harvesting work of the green soybeans 2 can be surely achieved. 5 is obliquely limited to a pair, and a configuration is adopted in which the beans strippers 4 and 5 and the transporting body 6 are arranged so as to be arranged in the front-back positional relationship, that is, in the moving direction of the moving base 3. Thus, the portion from which the green soybeans 2 are removed from the stem 1 can be configured with as small a width and a depth as possible, so that the size and weight of the moving base 3 can be reliably reduced. Therefore, the handling properties (operability and workability for loading and unloading to the workplace) are dramatically improved, and the cost properties (production cost and running cost) are also extremely excellent.

Further, in this embodiment, since the transporting body 6 is inclined so as to be parallel to the bean strippers 4 and 5, the green soybeans 2 can be received and transported more favorably. The reduction in size and weight of the moving base 3 is reliably achieved.

Further, in this embodiment, since the passing portion 7 formed in the carrier 6 is disposed below the stripping section 8 between the bean strippers 4 and 5, the stem 1 with the green soybeans 2 is removed. Thus, the beans can be reliably guided so as to pass between the bean strippers 4 and 5, and can be passed through the moving base 3, and therefore,
More efficient harvesting can be performed.

In the present embodiment, a closing member 9 is provided to prevent the green soybeans 2 which have been removed from passing through the passage portion 7 from passing therethrough.
Moreover, the closing body 9 has a moderate flexibility that allows passage of the stem 1 and is configured to allow passage of only the stem 1 by changing its shape according to the shape of the stem 1. Is employed, it is possible to prevent the removed green soybeans 2 from being discharged from the passage portion 7 to the outside of the moving base 3 as much as possible. Therefore, a good harvesting operation without wasting the green soybeans 2 is achieved. You can do it.
