Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a harvesting machine for harvesting crops such as maize and sorghum.

<Prior Art> In a harvesting machine for harvesting crops such as maize, for example, a maize harvester, as disclosed in the specification of Japanese Patent Application No. 57-175101, a reaping feeder is used to reap the maize and send it backward. A forward folding part is provided above the device for folding the maize into a forward folding position. This front-folding portion is generally configured such that the rod material is formed in a U-shape that widens in front when viewed from above.

<Problems to be Solved by the Invention> However, since the conventional method simply includes a U-shaped front-folding part, the maize that is knocked over by the front-folding part falls down, and the cutter of the reaping feeding device does not cut the maize. The so-called double-cutting phenomenon occurred in which the tip side of the stalk was cut again. The tips of the maize, which had been cut twice, fell onto the field and remained unharvestable.

<Means for solving the problems> The present invention solves these problems,
As a means for this purpose, in a harvesting machine for maize, etc., which is equipped with a front-folding part for folding the harvested material into a forward-folding position above the reaping feeder that reaps the material to be harvested, such as maize, and sends it backward, the front-folding part is installed. A pair of left and right guide parts are provided on the front side of the front side to guide the objects to be harvested toward the front-folding part. It is equipped with a receiving part.

When harvesting crops such as maize, when the harvesting machine moves forward, it guides the harvested materials through a pair of left and right guide sections to the front-folding section, and this front-folding section transports the harvested materials. Make things fall forward. On the other hand, the root side of the object to be harvested is cut by the cutter of the reaping and feeding device, and the root side is held and sent to the rear. Therefore, although the to-be-harvested items are forcibly fed while falling from the forward-folding position, since the to-be-harvested items are received by the receiving portion at this time, the to-be-harvested items do not fall down completely.

<Example> Hereinafter, the present invention will be described in detail with regard to the illustrated example.
In the figures and FIG. 2, 1 is a tractor that can be driven backwards, and 2 is a rear wheel. 3 is a harvester for maize 4, and is attached to the rear of the tractor 1 via a three-point linkage mechanism 5. This storage unit 13 is for two-row mowing and includes a divider 6, a cutting feed device 7, a shredding device 8, and a blowing chute 9. As shown in FIG. 3, the reaping feed device 7 includes a rotary cutter 10, a feed belt 11, and a feed drum 1.
2 are provided in pairs on the left and right sides, the root side of the maize 4 is cut by cutters 10 on the left and right sides, and the cut maize 4 is sent rearward by a feed belt 11 and a feed drum 12. Left and right cutters 10 and feed belt 1
The first class is assembled inside a pair of left and right covers 13,
Dividers 6 are provided at the front ends of the covers 13, respectively. The shredding device 8 has a casing 14 as shown in FIG.
, a flywheel 15, a blade 16a (D4fn), and a cutter (not shown) that cuts the maize 4 into small pieces as the flywheel 15 rotates, and sends the shredded pieces to the blowing chute 9. It is composed of

Reference numeral 16 denotes an upper cover that covers the upper part of the feed drum 12. A transmission mechanism for the drum is provided inside the upper cover 16, and a guide device 18 is supported on the upper cover 16 via a support rod 17. The guide device 18 is arranged above the reaping feeding device 7, and is configured as follows. That is, as shown in FIGS. 4 and 5, the guide device 18 includes a forward-folding portion 19 for tilting the maize 4 into a forward-folding posture, and a forward-folding portion 19.
It comprises a pair of left and right guide parts 20 provided on the front side of the machine, and a receiving part 21 for receiving the maize 4 guided from the guide parts 20 to the forward-folding part 19. Front-loaded section 19 of each article
is composed of two horizontal rods 22, and at both ends of the horizontal rod 22 there is a bent part 23 that spreads forward and slopes downward, and in the center there is a protrusion that protrudes and slopes similarly to the bent part 23. A rod 24 is provided respectively. Guide part 20 of each article
There are a pair of guide portions 20 on the left and right, and the guide portions 20 thereof are spread out in the front and are inclined similarly to the bent portions 23.

A receiving portion 21 is provided at the rear end of each guide portion 20 so as to be bent outward from the left and right. In this embodiment, the guide portion 20 and the receiving portion 21 at both the left and right ends are composed of bending rods 25 bent into a F-shape. By fitting outward, it is detachably attached with a pin 27. Further, the guide portion 20 and the receiving portion 21 on the center side are constituted by the periphery of a triangular rod 28 which is bent into a triangular shape, and the triangular rod 28 is detachably attached to the protruding rod 24 via a cylindrical portion 29 and a pin 30. installed. The receiving portion 21 is located in front of the cutter 10 of the reaping feeding device 7. 31 is a gauge import. 32 is a rotation guide body, and 33 is a guide rod.

In the above configuration, when harvesting the maize 4, the harvester 3 is driven forward while the tractor 1 is driven backwards (.Then, the divider 6 at the tip enters the root side of the maize 4 and divides the weeds. , the upper guide part 20 guides the maize 4 toward the front-folding part 19 side.Then, the root of the maize 4 is cut by the cutter 10 of the reaping feeder 7, and while the root is held by the feed belt 11. The maize 4 is fed rearward and fed into the casing 14 of the shredding device 8 in a substantially horizontal position by the feed drum 12. On the other hand, as the maize 4 moves forward, it is tilted forward by the forward tilting portion 19. Then, in the fallen state, the first sending bell
As the maze is sent backwards, it is pulled out in the longitudinal direction of the maize. However, after the maize 4 falls forward, it is received by the receiving part 21 and supported from below, so that the maize 4 may fall down in a horizontal state or with the tip side hanging down due to being pushed down by the foregoing part 19. This prevents the maize 4 from being cut twice by the cutter 10. The shredded maize is loaded onto a wagon or the like through a blow-out chute 9.

If the receiving part 21 is formed into a thin rod shape, the seeds of the maize 4 will be handled and dropped by the receiving part 21. Therefore, in that case, as shown in FIG. 6, if a large-diameter roller 35 is provided in the receiving part 21 so as to freely rotate, and this roller 35 receives the maize 4, the handling of the maize by the receiving part 21 is improved. can be prevented.

In addition, in the case of two-row mowing, the bent rod 25 and the triangular rod 28 are used in combination as described above, but in the case of single-row mowing, the forward tilting part 19 is shown in plan view as shown in FIG. U or V
It may be configured by making it into a letter shape and combining the bending rod 25 with this. Therefore, in this case, there is an advantage that the bending rod 25 can be used for both one-row mowing and two-row mowing. Of course, in the case of two-row mowing, it goes without saying that something like the one shown in FIG. 7 may be provided for each row.

Further, the forward tilting portion 19, the guide portion 20, and the receiving portion 21 may be integrally formed with one rod member.

<Effects of the Invention> According to the present invention, since the receiving part for receiving the harvested material guided to the front-tilting part side is provided, the to-be-harvested material that has been brought down by the front-tilting part does not fall any further, and the to-be-harvested material is It is possible to prevent things from being mowed twice by the reaping and feeding device. Furthermore, even though there is a receiving part, since the guide part in the form of a front bed guides the harvested items to the front-folding part side, the harvested items can be reliably sent to the front-folding part side.
