Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that reliably and stably transports cut grass and other thin stems of plants while elastically holding them without damaging them.

For example, in a conventional rice grass harvester, the cut rice is transported in nine hanging positions.
As shown in the figure, a pair of endless flat bells on the left and right) tll +
21, one of the flat belts (2) is pushed out from the inside into a convex curved shape, and the other flat belt (2) is elastically adhered to the flat belt (2). It is holding the stem culm (goods). However, in this case, both bells)
81 is a monotonous passage in which the stem culm (wealth) can simply move straight, so when the amount of stem culm that can be inserted into the passage changes slightly, the phenomenon that the stem culm is not clamped occurs. become.

In other words, as shown in Figure 1.2, both bells)

If the bulk part (a) is held in a sequential manner, the bulk part (a) is held without any problem, but the small part ('b) located immediately before or after it is held by the large part (a). They will fall out through the widened gap, and even the stem culm (goods) of the correct length will be thrown away. Even if the temporary stem does not fall off, the clamping pressure will inevitably weaken, resulting in misalignment of the stem culm in the small portion ('b). The above-mentioned belt (2) is elastically deformed by the stem culm (goods) into which it is inserted, and is clamped by the restoring force, and the clamping pressure changes depending on the amount of the stem culm. be.

As a preventive measure, conventionally, the above-mentioned stem culms (goods) are conveyed little by little by increasing the rotation speed of the belt to ill +21, but this tends to cause gaps between the stem culms (goods) themselves. In addition, it is necessary to ensure a long working length for conveyance, and there is also the problem that it is cost-effective to increase the overall length of the conveyance device.

The present invention is intended to solve these problems, and its specific configuration will be explained in detail based on the drawings.The illustrated embodiment represents the present study applied to a strawberry harvester, but Needless to say, it can also be applied to the stem culms of. In Figures 1 to 3, (10j is the generic name for the body of the rice harvester, and this is equipped with an engine (11).02) is also the transmission, intermediate shaft, belt, etc. It is transmission connected to the engine (11) via. N is a pair of left and right traveling crawlers driven by the engine (111) (151 is a hydraulic cylinder that removes dust, weeds, weeds, pulls up, and reaps the equipment (BL tel, the punishment end) From the side of the aircraft, operate the hinge river around the fulcrum 9 to raise and lower it.

The engine (the upper position is a bundling bed 07, and the rear position is a strawberry bundle loading platform 08), and the two are set in such a manner that they are continuous with each other. (I9) is the driver's cab that is sent out from the fuselage (10) to the rear,
Therefore, while operating the harvester from the cab (19),
The operator will be able to directly see the loading capacity of the strawberry bunches. Needless to say, the present invention can also be applied to a type of harvester that is operated by an operator while walking in the field. The above intermediate shaft (1) is a working power distribution shaft that extends horizontally parallel to the grain, and at one lateral end, the intermediate shaft is connected to the intermediate shaft via a transmission belt, bevel gear mechanism, etc. By being connected, the driving force from the engine (111) is distributed to various working devices.The working devices include the straw weeding device, the pulling device tB, and the reaping device tc+. It also includes a clamping and conveying device (ID), a sorting device (E), a convergence device (F), and a binding device (tG), and a series of actions by these devices are sequentially applied to the rush.

The clamping and conveying device jDl according to the present invention clamps the stem culms of rush grass that are erected by the action of dividing, pulling, and reaping, in nine postures, so to speak, hanging down upward from the rear of the machine body (10). As shown in Fig. 1.7, it is constructed at an upward slope that intersects the horizontal plane at a certain angle. Equipment (Bl's straw raising passageway +21)
The position is set at a desired height, facing correctly from behind, and corresponding to the tip side of the rush. Similarly, P2 indicates the end point of the conveying action.

As shown in FIGS. 1 and 2, this clamping and conveying device fD+ has one V-belt set (4) which is arranged in parallel (in three rows in the figure) separately and independently in the shed. It consists of a pair of left and right V-belt sets with the other V-belt set 4 which are in a corresponding parallel state, and each belt set has a pair of front and rear double-row type V pulleys (2 [9821η) so that they can circulate in The body 4 is supported by the required number (total of 3 in the figure) of freely rotatable double-row type intermediate parts that are supported in order to tension and bias one of the belt assembly parts from the inside into a convex curved surface shape. With the V pulley, the reed and its convex curved surface are in elastic contact with the other belt set back to back.
They are conveyed backwards (see the arrows in Figure 6) while being held between them, and the gripping conveyance path is designated by the symbol +81, and the working length is designated by the symbol fLl. Suggests.

In that case, as is clear from FIG. 3, the entrance of the clamping conveyance path ts+ is secured as a roughly ■-shaped retraction guide gap which expands at the front when viewed from the plane9, thereby allowing the strawberry stems to The culm (wealth) is smoothly conveyed into the holding conveyance path TST.
It is designed to be reliably retractable. (b) t31
1 is a double-row type V located at the rear of both belt sets (B) and (C)
These are drive shafts that rotate the pulley (to) angle, and both are connected to the power distribution shaft through a reduction gear box (t32@31), a transmission shaft (to), etc. (The sake plow is a fixed support shaft that freely rotates the double-row V-pulley i2 No. 1, which is also located at the front, and the frame that supports the 0 trowel Cη of this kind of support shaft ■ is installed inside the frame. Due to the enclosed spring lock,
A predetermined tension is applied to both belt sets (2)-. @2rX is a tension bearing rail fitted to the support frame (ai9sl) so as to be slidable in the front and rear directions.

In addition, ■ is stretched to the drive shaft +aIl of the rear double-row type V pulley (B) in the other belt set (C) described above, so that it can be rotated in one direction with the other belt group (C). This is a side feed belt for the tip end, and faces directly above the clamping conveyance path +81. i4@ is a double-row type interlocking V-pulley that hangs the intermediate position in one of the above-mentioned belt assembly, and the main shaft is the interlocking shaft for its rotational drive, which also has a retractable belt@for driving the force. V Boo 9 - A decoy is also permanently installed. A retraction belt 1471 that circulates integrally with the above-mentioned one belt set (3) is connected to it, and is finished as a so-called unit book with the belt 171. The other belt set (@ has the same meaning and is a unit with the above-mentioned ear tip side feeding belt) is shaped like ltm.

The retracting bell) 14η is an endless belt equipped with a lug (6), like its conveyor toe, and is used to clamp the straw stem culm (property) that has been correctly raised by the lifting device [Bl] from its lifting path +81. Both belt sets @(
C) It acts as a smooth guide to pull into the clamping conveyance path tst between the two, as if it were to be delivered, and therefore, the starting point P3 of the action is oriented slightly forward of the clamping conveyance path (8+). The gull is a driven V-pulley with a retraction belt of 0η.

A double-row intermediate pulley (c) that projects one of the parallel belts m(2) from the inside in a convex curved shape and urges it.
Especially the first one? As is clear from the figure, there is a certain level difference in the diameter dimension of the belt hanging surface of the plurality (three in the figure) of the belt hanging surface on which the belt assembly □□□ is hung. (9) is given, then the belt set (
As mentioned above, the other belt set (2) is supposed to be in elastic contact with each other back-to-back, so that the stem culm is held in the conveying path t based on the stepped circle.
s+ will be configured as a tortuous path. While the tubers and stem culms (wealth) are being conveyed while being conveyed in this pinching conveyance path (81),
, and will be subjected to a bending action in a shape of a letter or a zigzag shape, and therefore the amount of stems received in the conveyance path (8) may change slightly or become in a ball state. Even if there are variations, the stem culm (wealth) is always stably and reliably clamped and conveyed, and the strength of the clamping pressure can be completely compensated for. In this regard, in the figure, both belt sets 4- are not facing the left and right positional relationship when viewed from the plane 6-.
Since the natural drooping of the grass is carried in the vertical position, there is no risk that even straw grass with a regular length will be accidentally dropped and discarded, and the sorting effect is improved. You will be able to improve your life.

As is clear from Figures 1 to 3, while the grass is being pinched and conveyed toward the rear of the machine body t101 by the above-mentioned pinching and conveying device (), the grass is transferred to a conveying chain 15+1rI2 with a pair of upper and lower comb claws. A straight sorting device (g) consisting of combs the stems from the middle stem part toward the stock base, and at the same time feeds them in the left and right directions at right angles until they reach the height of the bundling bed 0η. The direction is changed as if it were lifted to a horizontally laid down position, and then the stock base side continues to be connected to the lug-equipped focusing bell of the focusing device IP+) 6
31 to the rear in an orderly manner, and as soon as a certain amount of the particles are focused on the converging section, they are bundled by the binding device IGI. Then, the bundled strawberry bundles are kicked out onto the end of the loading platform of the aircraft (lO). It should be noted that the above-mentioned clamping and conveying device can also be used in an installation configuration where it clamps and conveys the stems (wealth) of rushes and other plants in a horizontal, prone position.

As described above, the stem culm (property) clamping and conveying device according to the present invention is equipped with at least a pair of front and rear double row pulleys I241.
One set of belts (2) is suspended so as to circulate around (to), and along the way, the required number of double-row intermediate pulleys (c) project from the inside in a convex curved shape and are biased. Similarly, a pair of front and rear double-row type boots (3) are stretched so as to circulate around the H area, and by elastically contacting the convex curved surface of the belt group (3), one of the belt groups (3) 2) and the other parallel belt set 123) that can hold and convey the stem culm (goods) between them. By providing the step (6), the clamping conveyance path ts+ of the C1 stem culm (property) is determined to be a curved path, so the first θ~
The conventional deficiency β (^) as described at the beginning based on Figure 7.2 is completely eliminated, and the necessary configuration is extremely simple and sufficient.

In other words, changes in the clamping pressure due to the amount of stem culm, etc. are compensated for by the bent form of the clamping conveyance path +81, and a stable and reliable clamping and conveying action can always be maintained. Therefore, it is possible to slow down the conveyance speed, and the length tLl of the clamping conveyance action can be significantly shortened to 4 ml, making it possible to significantly downsize and compact the entire fruiting device. In this sense, it can be said that it is particularly effective when applied to a straw harvester where work efficiency is questioned in relation to Odate and the like.

Furthermore, if a retraction belt 0η with lugs 149) that circulates integrally with the belt set @(c) is connected to at least one of the belt sets @(c) to form a unit, in addition to the above-mentioned effects, The receiving of the stem culm (property) in the bent-shaped clamping feed path tel is of great practical benefit in that the feeding action can be performed automatically and the smoothness and reliability can be further improved.
