Description

[Detailed Description of the Invention] The present invention relates to a crimper-type conditioner that prevents grass from adhering to the upper roll.

A crimper-type heacon desilder uses a pair of upper and lower gear-shaped rolls to crush grass and accelerate drying.The crimper-type heating machine uses a pair of upper and lower gear-shaped rolls to crush grass and accelerate drying. Because the top surfaces face each other, if you bite into a leaf of the leguminous family, which has a high nutritional content, the leaf will be pressed against almost the entire trough and may stick to the upper roll, causing it to wrap around the entire circumference of the top roll. , which causes a decrease in processing capacity.

In view of the conventional problems as described above, the present invention has developed a detachment part that forms a space for preventing adhesion between the valley part of the upper roll and the biting grass by at least the valley part of the upper roll and the tooth part of the lower roll. It is an object of the present invention to provide a crimper type conditioner which is formed on one side to prevent grass from adhering to the conditioner.

The features of the present invention for achieving this purpose include a gear-shaped upper roll 25 whose outer periphery is made of a rubber-like elastic material, and a gear-shaped lower roll 26 that can engage with the upper roll 25. In a crimper-type conditioner that crushes the cut grass A while biting it, the troughs and lower part of the upper roll are used to form a space for preventing adhesion between the grass bited between the upper and lower rolls and the trough part of the upper roll. At least one of the toothed portions of the roll is formed with a detachment portion that presses the grass against the other side and brings it into approximately line contact.

The invention will now be described in detail with reference to the illustrated embodiments.

In Figures 1 to 3, 1 is a tractor;

Each rotary disk 9 is made into a set of two, and each set is driven in opposite directions so that the cut grass gathers in the center. Note that the driving force is that of the tractor 1.
From the PTO shaft 12 to the universal joint shaft 13 and input shaft 14
, and the belt transmission mechanism 1 inside the belt cover 15
6, it is transmitted to each rotating disk 9 via each transmission system in a gear case 7 and a transmission case 8.

A safety frame 17 located above the reaping section 11 is attached to the gear case 7. The safety frame 17 includes an inverted L-shaped support 18 that is supported in a cantilevered manner on the gear case 7 and extends laterally along the reaping section 11, and is fixed to the support support 18 and protrudes forward and backward from the reaping section 11. A pair of mounting brackets 20 are fixed to the support column 18 at a predetermined interval in the lateral direction.

The conditioner 3 includes a pair of left and right side plates 23, and a pair of upper and lower rolls 25, 26 parallel to each other and supported by each side plate 23 to be rotatable about a horizontal axis via a bearing member 24 or the like. .

Each side plate 23 is bolted or welded to the mounting bracket 20, and the conditioner 3 is disposed at a required height behind the mower 2.

A transmission case 28 is provided on the left side plate 23, and a chain transmission means 29 is disposed within this transmission case 28 as shown in FIG. The input shaft 30 and the support shaft 31 of the lower roll 26 are the left and right side plates 2
3, and are rotatably supported by sprocket 3, respectively.
2 and 33 are provided, and the support shaft 34 of the upper roll 25 and the idler shaft 35 are supported by a support plate 37 that is pivotally supported on the side plate 23 via a pivot shaft 36, and the support shaft 34 is 23 and is movable up and down, and is provided with a sprocket 39. An idler sprocket 40 is fitted onto the idler shaft 35 so as to freely rotate.

A chain 41 is connected to each of the sprockets 32, 33, 39, and 40, so that the power of the input shaft 30 can be transmitted to the support shafts 31 and 34, and the support shafts 31 and 34 rotate in opposite directions. The input shaft 30 is connected to an output shaft 44 of a gear case 43 fixed to the belt cover 15 via a universal joint shaft 42.
It is driven by power from the input shaft 14.

The upper and lower rolls 25 and 26 have gear-shaped longitudinal sections, and each has a plurality of teeth 25a and 26a and troughs 25b and 26b formed at equal intervals so that they can engage with each other.

The upper roll 25 has a cylindrical body 46 whose at least the outer periphery is made of a rubber-like elastic material and is fixed to the support shaft 34.
The mating is fixed. The lower roll 26 is made of steel. Teeth 25a of the upper and lower rolls 25, 26,
26a and troughs 25b, 26b are long in the axial direction,
It is formed in a spiral shape or parallel to the axis.

In the first embodiment of the present invention shown in FIG. 4, a protrusion 47 facing the teeth 26a of the lower roll 26 is integrally formed in the trough 25b of the upper roll 25. This protrusion 47 has a triangular longitudinal section and is formed along the entire length of the valley 25b. The cross-sectional shape of the projection 47 may be a polygon such as a quadrangle or an arc shape in addition to a triangle.

When pasture A is inserted between the upper and lower rolls 25 and 26,
The teeth 25a and 26a of both rolls 25 and 26 bend and crush the grass A. At this time, the teeth 26a of the lower roll 26 try to press the grass A relatively against the troughs 25b of the upper roll 25. Conventionally, at this time, the top surface of the tooth portion 26a is located at the valley portion 25.
The pasture A is moved to the valley part 25 by rolling motion against b.
However, in the present invention, since the protrusion 47 is interposed, the lower roll 26
The protrusion 47 is compressively deformed by the pressing force, and a space B is created between the grass A and the trough 25b before and after the protrusion 47, and the grass A does not come into surface contact with the trough 25b, but only has a line contact ( (substantially only contacts the protrusion 47).

The protruding portion 47 serves as a separation portion C that forms an adhesion prevention space B, and can prevent the grass A pressed against the valley portion 25b from adhering. Furthermore, since the protrusion 47 is made of an elastic material integrally molded with the upper roll 25, the grass A can be pulled away from the trough 25b by restoring after compression deformation, so that adhesion can be prevented more reliably.

In the second embodiment shown in FIG.
It is provided on the top of the upper roll 25, is formed of metal or a rubber-like elastic material, and faces the trough portion 25b of the upper roll 25.

The adhesion of the grass A to the troughs 25b of the upper roll 25 is caused by the troughs 25b and teeth 26a rolling over a long distance and clamping the grass A, and the clamping pressure is 1. If it is a point, a space B will be created between the front and rear portions of the grass A at the clamping pressure point and the valley portion 25b, so that no adhesion will occur.

In the third embodiment shown in FIG.
A concave portion 48 is formed in the valley portion 25b of No. 5,
A space B between the grass A and the grass A that are bitten in this recess 48.
occurs.

The portions that are relatively protrusions 49 before and after the recess 48 are portions that are in line contact with the pasture A,
Since it is elastically deformed by the pressure of the lower roll 26,
Like the protrusion 47 of the first embodiment, it has the effect of separating the grass A from the trough 25b. That is, the recess 4
8 and the protrusion 49 form a detachment section C, and the space inside thereof serves as an adhesion prevention space B.

The number of protrusions 4 in the first and second embodiments is not limited to one for each trough 25b or tooth 26a, but may be a plurality, and also in the third embodiment. , a plurality of recesses 48 may be formed, or they may be formed on the teeth 26a of the lower roll 26, and further, protrusions may be formed on the troughs 25b, 26b or both of the teeth 25a, 26a of the upper and lower rolls 25, 26. 47 or a recess 48 is also possible.

That is, in the present invention, at least the troughs 2 of the upper roll 25 where grass A is more likely to adhere than the lower roll 26
5b and the bitten grass A to reduce the amount of contact of the grass A with the trough 25b so as to bring the grass A into approximately line contact.In order to form the space B, the projection 47 Alternatively, a detachment portion C such as a recess 48 is formed.

Note that since the bending of grass A is performed by the teeth 25a and 26a of the upper and lower rolls 25 and 26, the bending action is not hindered even if space B is provided, but the troughs 25b of the lower roll 25 and Tooth portion 26a of lower roll 26
The crushing effect caused by this is slightly reduced. However, since the pressing force is concentrated on the protrusions 47 and the protrusions 49 before and after the recesses 48, creases or splits are likely to occur, and the overall crushing effect is not reduced.

According to the present invention described in detail above, the grass detachment portion C is formed in at least one of the valley portion 25b of the upper roll 25 and the tooth portion 26a of the lower roll 26, the outer peripheral portion of which is formed of a rubber-like elastic material, Grass A and the upper roll 25 caught between the upper and lower rolls 25 and 26
Since the adhesion prevention space B is formed between the upper roll 25 and the trough portion 25b, the grass A is reliably prevented from adhering to and wrapping around the upper roll 25, and a good crushing process can always be performed.
