DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a crop harvest for harvesting bulb crops such as onions and root crops such as carrots (hereinafter collectively referred to as "ground crops" or simply "crops"). About the machine.

[0002]

2. Description of the Related Art A harvester in which a leaf is cut when a crop is transferred to a neck holding and transferring device from a leaf holding and transferring device for extracting crops vegetated in a field and conveyed backward is disclosed in Japanese Unexamined Patent Application Publication No. Hei 9-1997. It is known in, for example, Japanese Patent No. 84427. This conventional harvester is of a walking type, and is provided with a weeding device, a scraping device, a leaf holding and transferring device, a neck holding and transferring device, a leaf cutting device, an alignment device, and the like from the front thereof, The leaves of the crops vegetated in the field are weeded by a weeding device, raked by a scraping device, and then transported backward while being clamped by the leaf clamping and transferring device, thereby pulling out the neck while transferring the neck. Then, the leaves are cut by the cutting device in a state where the neck portion is sandwiched therebetween, and then the bulbs (balls) are dropped and supplied in a state where they are aligned in the field, and the crops in this field are united and harvested in a later step. Was.

[0003]

In the above-mentioned conventional crop harvesting machine, the belt of the neck holding and transferring device has an elastic body fixed to the outer peripheral surfaces of the left and right holding belts, so that the belt width tends to be large. Therefore, there is a problem that the length of the leaf portion sandwiched between the belts becomes longer, and when cutting the foliage, the foliage projecting from the bulb portion becomes longer, and it is necessary to cut again.

In addition, since the elastic members are fixed to the left and right holding belts, the flexibility of the belt is deteriorated, and the rotation radius of the pulley must be increased. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to reduce the cutting length of foliage so that re-cutting of foliage is not necessary, and to reduce the size of the neck holding and transferring device.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the present invention
A pair of left and right transfer belts that hold the bulb portion of the extracted crop from the left and right and convey it rearward, and a drive pulley and a driven pulley disposed at the front and rear ends of the transfer belt. In the crop harvester provided with a neck clamping transfer device having a point, the transfer belt has a curved surface on the outer peripheral surface that matches the curved surface of the neck of the bulb portion, and a groove on the inner surface that fits the pulley. is there.

Accordingly, the transfer belt has a curved surface on the outer peripheral surface and has a groove on the inner surface, so that the transfer belt has a shape close to a rope. Therefore, the flexibility of the belt is increased, the radius of the pulley can be reduced, and the size of the neck holding and transferring device can be reduced. Therefore, it is possible to use a plurality of transport devices. In addition, since the transfer belt has a curved surface on the outer peripheral surface that matches the curved surface of the neck portion of the bulb portion, the cutting device can be held closer to the bulb portion, and the cutting device is reduced due to miniaturization of the pulley and the like. It can be located below. Therefore, cutting can be performed near the base of the foliage, and there is no need to cut the foliage again. Also, since the outer periphery of the pulley fits into the groove, the pulley is within the width of the transfer belt, so that the pulley or the like does not hit the crop during transportation of the crop and is not damaged.

It is preferable to provide a belt guide which fits into the groove of the transfer belt, on the back side of the surface of the transfer belt that holds the bulb. With this configuration, the belt guide is fitted to the transfer belt, and the traveling position of the transfer belt is fixed, so that the transfer belt does not sag or curl up without giving a considerably strong tension, and the bulbs do not rise. Since the transfer belt holding the portion is positioned and the bulb portion can be conveyed at a fixed position, the foliage can be cut at a fixed length. When the bulb portion is pinched between the left and right transfer belts, the transfer belt tends to expand outward, but the swelling is prevented by the belt guide, and the bulb portions are firmly pinched from both sides. For this reason, although the belt width is small and the nipping surface of the bulb portion is small, the bulb portion does not fall and is conveyed while the bulb portion is being nipped.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 showing the overall configuration in a side view and FIG. 2 showing a plan view, a harvester 1 according to the present invention is a walking type that can run (forward / reverse) freely in a longitudinal direction of a ridge over a ridge A. A pair of left and right drive wheels (rear wheels) 2A and 2B are provided, and a gauge wheel (follower wheel, front wheel) 3 is provided only on one of the right and left sides (shown in the figure).

From the front to the rear, the harvester 1 has a weeding device 4, a scraping device 5, a leaf nipping and transferring device 6, a neck nipping and transferring device 7, and a portion between the leaf nipping and transferring device 6 and the neck nipping and transferring device 7. And a pair of left and right subsoilers 10 for expanding and softening the ridge A in the vicinity of the gauge wheel 3 in order to facilitate pulling out. Each drive unit is linked to the engine 11.

The engine 11 is mounted on the rear of the machine frame 12 framed in a U-shape in plan view.
The mission in the mission case 13 is directly connected to the output unit. The missions in the transmission case 13 are a traveling system mission and a working system mission (power system such as a weeding device and a pick-up device). The traveling system mission is a chain transmission in a pair of right and left transmission cases 14A and 14B. The driving wheels 2A and 2B are linked to the body so that the traveling speed of the driving wheels 2A and 2B can be changed at a predetermined speed.

One of the left and right transmission cases 14A and 14B, the left transmission case 14B in the figure, is provided via a left-right expansion / contraction guide mechanism 15 provided at the rear of the machine frame 12 and a telescopic transmission cylinder 16 having a nested structure. Expand and contract in the left and right directions
The tread is adjustable in accordance with the width of the ridge A shown in FIG.
A and 2B can roll on the ridge groove A1.

The work system transmission receives power from the weeding device 4 via a transmission shaft system 17 shown in FIGS. 1 and 2, and the transmission shaft system 17 is inclined forward and extends forward. Power is input to the scraping device 5, the leaf nipping and transferring device 6, and the like via a power distribution system 18 having a bevel gear or the like built in the shaft system 17. The weeding device 4 includes a weeding transmission case 19 erected at the end of the machine casing 12, sprocket wheels 20 and 21, which are rotatably supported on upper and lower portions of the case 19, and rotate around right and left axes.
A chain 22 wrapped around 0, 21, a lifting claw 23 attached to the chain 22 so as to be able to move up and down in the longitudinal direction, and a lower part of the weeding transmission case 19 that extends forward. (See FIGS. 1 to 4).

In the present embodiment, three grass weeding transmission cases 19 are inclined in the forward downward direction and are spaced in the left-right direction.
By circulating the chain 22 in the direction indicated by the arrow X, the foliage B1 lying down in the left and right direction of the crop B can be scooped up from below by the raising claws (tines) 23 so that it can be aligned in the front-rear direction. (See FIG. 2). Here, the weeding transmission case 19 of the weeding device 4 corresponds to one between the shoulder A2 of the ridge A and two between the strips of the crop B, as shown in FIGS. Raise the foliage B1 that hangs down from the part A2 and the foliage B1 that lays down between the streaks.
By scooping up in step 3, the foliage B1 facing in the left-right direction is aligned in the front-rear direction.

The weeding rod 24 in the weeding device 4 is extended from the lower part of each weeding transmission case 19 in a downwardly inclined shape, and is directed in the lateral direction in preparation for scooping by the scraping claw 23. Grass is gradually lifted. Here, each weeding rod 24 is formed as a forked portion 24A near its stem (attachment portion to the case), surrounds the lower part of the transmission case 19 from both left and right sides, and At the start, weeding guides the stalk B1 so that the weeding rod 24 corresponding to the shoulder A2 of the ridge A extends more than the other weeding rods 24 (which are almost in contact with the ridge A). The length is long (see FIG. 2), and the foliage hanging over the shoulder A2 and the foliage that is lodged on the streak are gradually lifted.

The weeding rod 24 corresponding to the shoulder portion A2 is provided with a weeding cover 25 which extends outward in the left-right direction and is bent in the shape of an "H" in a side view. The weed cover 25 almost covers the gauge wheel 3 from above, and prevents the long foliage, which had been laid down, from being lifted up by the weeding rod 24 and stepped down by the gauge wheel 3 when it is again laid down. doing.

That is, the weeding apparatus 4 controls the harvester 1
Foliage B lying on ridge A when running along

Fig. 2 shows that the foliage B1 is scooped up (paid up).
As shown in the figure, the shape is adjusted in the front-rear direction, and the trapping device 5 is used to form a trapped shape from the left and right.
The foliage B1 of the crop B, which lays down and is intertwined in a complicated manner, is trimmed in the front-rear direction to prepare for the next raking device 5.

Here, as shown in FIG.
At the bottom of the picking start portion (lower wheel winding portion), the foliage lifted by the weeding rod 24 at a distance of H from the top surface of the ridge A is scooped up, and the weeding rod 24 Also, when weeding is performed in combination with left and right weeding in the part 24A, scooping of the foliage B1 by excessive force is reduced, and crop B is prevented from being pulled out from ridge A.

That is, although the chain 22 of the weeding device 4 circulates at a slower (slower) speed than the scraping belt of the scraping device 5, the chain 22 of the weeding device 4 does not Since the peripheral speed is faster than the peripheral speed of the straightened portion (the portion where the claw 23 stands on the front side in FIG. 4), the entanglement of the foliage is gradually released by the weeding rod 24 and excessive foliage is caused by the claw 23. The crop B is prevented from being pulled out unexpectedly.

By arranging the picking claws 24 of the weeding device 4 in the circulating chain 22, the weeding is ensured even when long and short stems and leaves are mixed. When the claw 24 is inverted from the upper winding portion, as shown in FIG. 4, it is supposed to fall down substantially along the chain 22. Here, the leaf scraping device 5 following the weeding device 4 The fore-and-aft interval is made as small as possible so that foliage immediately after weeding and shaping in the anteroposterior direction can be scraped from the lateral direction.

The weeding device 4 and the leaf scraping device 5 are shown in FIG.
As shown in FIG. 4 and FIG. 4, they are inclined forward and downward (inclined rearward and upward) and are provided in parallel with each other at an interval in the front-rear direction, and their height in the vertical direction is substantially the same. As shown in FIGS. 2 and 3, the leaf scraping device 5 winds an endless revolving body 27 represented by an endless belt over an upper driving pulley 25 and a lower driven pulley 26 so as to freely circulate. Built-in left and right transmission cases 28A, 28B
And an endless revolving body 27 indicated by an endless belt has a plurality of protruding rake claws 28 which are arranged in an inclined manner with a receding angle with respect to the running direction. The tips of the claws 28 cross each other at a rear position corresponding to the center weeding case in the weeding device 4, where two foliage B, which are weeded in the front and rear direction by the weeding device 4, are arranged.
By lifting the sheet 1 in a embracing manner from the left and right, the sheet 1 is stretched linearly, and the succeeding (transfer) to the succeeding leaf holding and transferring apparatus (drawing belt apparatus) 6 is smoothly and reliably performed.

At the starting portion of the leaf scraping device 5 (the portion wound around the driven pulley 26), the tip of the scraping claw 28 is located near the neck of the crop B. From the root of the foliage, the grass can be embraced in the right and left direction.

That is, the leaf scraping device 5 circulates and rotates the endless revolving body 27 in the direction indicated by the arrow Y in FIG. By lifting while inserting, even the long and short stems and leaves can be surely stretched in a straight line and delivered to the succeeding leaf-portion holding and transferring device 6. The leaf nipping and transferring device 6 is shown in FIGS.
