Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a harvester, for example, a harvester having stems and leaves of onions, etc.

Generally, when onions are harvested, the onions that have been dug up are often transported to a conveyor or the like and stored in containers, but in this case, the onion stems and leaves are It is being removed from onions.

However, if the onions are dry, the onions flow too quickly on the conveyor, resulting in many mistakes in cutting the stems and leaves. On the other hand, if the onions are wet and there are many stems and leaves, the flow is poor and the onions are cut too quickly. There are problems such as the possibility of damaging the

Therefore, the present invention was devised in view of these points, and includes a foliage processing mechanism that removes and transports the foliage of the harvested material, and an endless chain is provided above the foliage processing mechanism so that it can rotate freely. With,
A plurality of control plates for controlling the conveyance of harvested products on the above-mentioned foliage processing mechanism are rotatably attached at a predetermined interval between these opposing endless chains, and each control plate is used to control the transportation of harvested products such as onions. To provide a harvesting machine that is capable of suppressing and controlling the flow of the harvested material on the above-mentioned foliage processing mechanism to an appropriate speed according to the harvesting conditions, thereby making it possible to reliably remove the foliage without damaging the harvested material. It is something to do.

Next, one embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a machine frame, and this machine frame 1 has a pair of side frames 2 arranged opposite to each other at a predetermined interval, and a support frame 3 is protruded from the upper front end of the pair of side frames 2.

Next, 14 is a foliage processing mechanism, and this foliage processing mechanism 14 is connected to the discharge end of the conveyor 8 with the rear thereof inclined low. The above stem and leaf processing mechanism 1
4 is constructed in the form of a roller conveyor, with multiple sets of rollers 15 arranged in parallel in the width direction with respect to the advancing direction of the machine frame 1, and each set of rollers 1
A ridge 16 for feeding crops such as onions backwards is spirally formed in the axial direction around one roller 15a of 5, and one roller 15 having this ridge 16
A is arranged every other time. The rollers 15a having each set of protruding edges 16 are interlocked and driven by an interlocking means (not shown), and the other rollers 15 are driven in the opposite direction.Therefore, one set of rollers 15 is driven in the opposite direction. The harvested products such as onions are transported backwards by each set of rollers 15, and the stems and leaves thereof are held between the rollers 15 and cut and removed as they move. . And this foliage processing mechanism 1
An interlocking shaft 17 is protruded from the tip of one roller 15a having a protruding edge 16 at one end of the roller 15a.
They are designed to be driven in conjunction with each other.

Reference numeral 19 denotes a control mechanism for controlling the flow of the harvested material, and this control mechanism 19 is disposed above the foliage processing mechanism 14. The control circuit mechanism 19 is an endless structure in which a large number of link plates 21 are rotatably connected by a shaft 22 between sprockets 20 rotatably mounted on both front and rear sides of the foliage processing mechanism 14. A chain 23 is rotatably suspended, and is fixed to both sides of a support frame 25 having a substantially L-shaped cross section through opposing support shafts 24 with a predetermined interval between the endless chains 23 on both sides. A bearing block 26 is rotatably supported, and a control plate 2 made of a rubber plate or the like is mounted on a vertical piece 25a located between the endless chains 23 of each support frame 25.
The upper part of the control plate 27 is fixed with bolts 28 and nuts 29, and the lower end of the control plate 27 is extended so as to come into sliding contact with each roller 15 of the foliage processing mechanism 14. horizontal piece 2
A locking protrusion 30 that locks onto the endless chain 23 is horizontally protruded from both ends of the chain 5b in the width direction.
A drive shaft having a sprocket 20 mounted on the front portion of one side of the control mechanism 19 is interlocked with the drive shaft 9 of the conveyor 8 via a transmission medium 31. Further, a restraining plate 32 is disposed above the control mechanism 19 to suppress rotation of each control plate 27 located above.

Next, a transverse conveyor 33 is rotatably disposed at the rear end of the foliage processing mechanism 14, and a container (not shown) is provided at the discharge end of the transverse conveyor 33. And this horizontal conveyor 3
3 is operatively connected to the drive shaft 9 of the conveyor 8 via a transmission medium 34.

In the figure, numeral 35 is a grounding ring that is attached so that its height can be freely adjusted.

In the device configured in this way, the machine frame 1 is connected to the tractor via the connection frame 6, and
The input shaft 4 of the transmission 5 is connected to the output shaft of the tractor via a power transmission shaft.

When the machine frame 1 is pulled by the tractor and the transmission 5 is driven in conjunction via the power transmission shaft, the conveyor 8 and the rollers 15 of the stem and leaf processing mechanism 14 are driven in conjunction via the chain 13, the control plates 27 of the control mechanism 19 rotate in conjunction, and the cross feed conveyor 33 is also driven in conjunction.

As a result, onions as a harvested product are dug up by the tip 7, transferred to the conveyor 8, conveyed backward and upward while being sieved with soil on the conveyor 8, and further transported to the conveyor 8.
The leaves are transported from the delivery end onto a roller conveyor-like foliage processing mechanism 14.

At this time, if the onion is dry, each control plate 27 of the control mechanism 19 is rotated around the support shaft 24 in advance, as shown in FIGS. 2 and 3.
The locking protrusion 30 is locked on the link plate 21 on the rear side of the support shaft 24 in the direction of travel, and each control plate 27 is arranged so as not to rotate forward in the direction of travel. As a result, the onions carried onto the foliage processing mechanism 14 do not quickly flow backward along the inclined surface, and are prevented from moving backward by the rotating control plates 27, while being kept at a predetermined level. It is moved by each set of rollers 15 rotating at a high speed,
Along with this movement, the onion stems and leaves are held between a pair of rollers 15 and cut and removed.

In addition, if the humidity of the onion is high and there are many stems and leaves, each control plate 27 of the control mechanism 19
Rotate clockwise in Figure 3 around the support shaft 24,
As shown in FIG. 4, the locking protrusion 30 is
4 on the link plate 21 on the front side in the direction of travel, and each control plate 27 is arranged so as not to rotate rearward in the direction of travel. As a result, even if the onions carried onto the foliage processing mechanism 14 have a poor flow backwards along the slope and may form a tight band on the foliage processing mechanism 14, each onion that moves The control plate 27 sequentially pushes the onion at a predetermined speed to promote its movement, and as it moves, the onion stems and leaves are held between a pair of rollers 15 and cut and removed.

In the above case, each control plate 27 of the control mechanism 19 is sequentially moved by the endless chain 23 without changing its direction while its rotation is suppressed by the suppressing plate 32 in the set direction. Then, the onions without stems and leaves are further conveyed to a lateral conveyor 33 and stored in a container.

According to the present invention, a plurality of control plates for controlling the transportation of the harvested material are rotatably mounted on an endless chain via a support shaft on a foliage processing mechanism that transports the harvested material while removing the foliage. A locking protrusion is provided on one side of the upper end of each control plate to selectively lock onto the endless chain in the front and rear parts around the support shaft by rotation, so that crops such as onions can be harvested. By regulating the rotation direction of each control plate according to the conditions,
The flow of the harvested material on the foliage processing mechanism can be reliably suppressed and controlled; that is, when the harvested material is dry, the control plate is rotated in the rotating direction of the endless chain by each locking protrusion. It is possible to control the speed of the flow of the harvested material by setting it so that the flow of the harvested product is not rapid. Also, when the humidity is high and there are many leaves and stems, each locking protrusion allows the control plate to move in the direction of rotation of the endless chain. can be set to rotate to facilitate the flow of the crop, thus
In either case, the stems and leaves can be reliably removed and transported without damaging the harvested product, making it particularly suitable as an onion harvester.
