Description

[Detailed description of the invention] The present invention provides a cover for transporting and guiding stem culms to be bound in a sideways posture to a binding part, such as a waste straw binding device provided in series with a threshing device, and the binding part. Regarding a stem culm tying device that is provided with a communication guide rod that guides the plant base and the tip of the plant across the tying string guide plate located therein, the purpose thereof is to:
The aim is to improve the bundling and release performance with a simple structure that merely improves the communication guide rod.

First, an embodiment of the present invention will be described based on the drawings. The drawings show a waste straw tying device B to which the present invention is applied, which is arranged in series with a threshing device A.

In the figure, reference numeral 1 denotes a binding section located below the rear printing plate with respect to the conveyance end of the waste straw discharge path C, and at this upper position, the binding string is removed from the string roll 7 by swinging back and forth. A needle 9 is disposed to be wound around the waste straw bundle fed out and bundled in the bundling part 1, and a bundling string guide plate 3 is disposed at a lower position corresponding to the needle 9.
Further, on the lower surface side of the guide plate 3, there are provided a holder 11 and a billet 10 for knotting the binding string wound around the bundle of waste straw.

D is a passage for conveying and guiding the waste straw in a sideways position in the binding part 1, and in the upper position of this passage, a chain 13 for feeding the waste straw with a removal straw locking protrusion 12, and a waste straw scraper are provided. A compact packer 14 is disposed, and a cover 2 on which waste straw is placed and slidably guided is disposed at the lower position.

Reference numerals 4 and 5 indicate communication guide rods 7 that are located between the cover 2 and the guide plate 3 and slide and guide the stock and ears of the waste straw; The guide rod 5 on the tip side has a free end portion 5a curved upward and toward the seam side of the discharged straw.

According to the above configuration, both the guide rods 4 and 5 allow the binding portion 1
The waste straw located at
The posture of the discharged straw is stabilized to ensure the converging and binding action in the binding part 1, and the curved free end portion 5a of the tip side guide rod 4 provides resistance to the tip of the discharged straw. By applying the resistance acting portion while gradually moving toward the tip side, the release action can be performed with the stock head in the leading position, while the tip is smoothly separated from the roadside portion 5a.

As described above, in the stem culm binding device described at the beginning, the present invention extends the guide rods 4 and 5 from the binding section 1 to the tied stem culm discharge port 6, and also extends the guide rods 5 on the tip side. By simply improving the structure by curving the free end portion 5a of the culm upward on the tip side of the culm of the tying stem, the culm can be stably removed during tying so that the culm does not fall off or its posture is disturbed. Not only can the binding action be performed reliably and well, but also the action of releasing the bundled stem culm in a certain tilted position with the plant head in the lead can be performed smoothly and reliably. This allows the direction of straw culm elongation and the direction of straw discharge to be changed to be approximately the same, and the straw can be discharged very smoothly, as if it were slipping through the binding part 1, with very little catching on other objects. However, the outside of the rod that provides the resistance binds the waste straw to the binding part 1.
Since it is formed continuously and integrally from the guide rod 5 that slides and guides the device, there is no impact or strain on the user when changing the posture, and even smoother release can be performed, which is an extremely useful advantage as a binding device. has.

As shown in FIG. 4, on the outer periphery of the waste straw binding device B, a frame 16 is disposed on which a seat cover 15 is stretched to cover the binding device B when the binding device is not in operation. The seat cover 15 is provided with a pocket 17 for the spare roll 7', and a portion 15A of the cover corresponding to the stock base of the waste straw to be transferred to the bundling device B is in contact with the stock base of the waste straw. Make sure it bulges outward so that it doesn't.
