Description

[Detailed description of the invention] Industrial application field This invention is a grass and rice straw forming machine that forms collected grass and rice straw into briquettes. This invention relates to a briquette removing device that can easily remove briquettes as cylindrical briquettes when they occur, while continuing the molding operation.

BACKGROUND OF THE INVENTION Various types of pasture and rice straw forming machines are already known, which transfer grass and rice straw raked and collected in a pick-up section to a forming section and form them into cylindrical briquettes. The forming section has a briquette forming chamber formed by arranging a plurality of forming rollers on the same circumference, and feeds grass or rice straw between the forming rollers or from one end of the forming rollers to fill the briquette forming chamber. The briquettes formed by compression molding are delivered from the other end.

Problems to be Solved by the Invention However, in the grass and rice straw forming machine configured as described above, grass and rice straw are sequentially supplied to the briquette forming chamber formed by a plurality of forming rollers, and the formed briquettes are Since the sequential delivery process is repeated, if the amount of grass or rice straw supplied excessively exceeds the amount of briquette delivered, the density of the briquette becomes too large to be formed and delivered, and clogging occurs in the briquette forming chamber. Once a blockage of briquettes occurs in the briquette forming chamber, the work cannot be continued unless the blockage is removed, but the outlet of the briquette forming chamber is relatively small.
Furthermore, since a briquette cutting device and the like are provided there, it is not easy to remove the tightly packed briquettes, and a great deal of labor and time is required.

Therefore, in view of these problems, the present invention was developed by
To resolve the condition while continuing the forming operation of cylindrical briquettes even if the density of briquettes becomes abnormally high or clogging occurs in a briquette forming chamber composed of a plurality of forming rollers. The object of the present invention is to provide a briquette removal device for a pasture and rice straw forming machine that can perform the following steps.

Means for Solving the Problems The present invention has the following technical means for achieving its purpose. That is, the briquette removing device in the grass and rice straw forming machine according to the present invention transfers the grass and rice straw raked up and collected by the pick-up section installed at the front of the machine to the forming section at the rear of the machine and forms them into briquettes. In the pasture and rice straw forming machine, the forming section has a briquette forming chamber surrounded by a plurality of forming rollers, and the briquette delivery side bearing of each forming roller is connected to the briquette through an eccentric body that is rotatable about the axis. It is characterized in that it is supported so that the outlet of the briquette forming chamber can be expanded.

Function The above technical means of the present invention works as follows.

That is, grass and rice straw transferred from the pick-up section at the front of the machine to the forming section at the rear of the machine are supplied to the briquette forming room between the forming rollers, and are compression-molded into briquettes, and the formed briquettes are The briquettes are sequentially delivered from the delivery port of the briquette forming chamber. The briquettes sent out from the briquette forming chamber are cut into predetermined lengths and then released.

By the way, if the amount of grass or rice straw supplied to the briquette forming chamber and the amount sent out as briquettes are balanced, the density of the briquettes in the briquette forming chamber will be maintained at an appropriate level, but if the amount supplied is excessive. In this case, the density of the briquette becomes abnormally high, which may make it impossible to mold and deliver the briquette, or cause clogging. In such a case, by turning the eccentric body with respect to the axis, the briquette delivery side bearing of each forming roller can be eccentric and the delivery port of the briquette forming chamber can be widened, making the forming operation easier. If this continues, loosening will occur in the briquette forming chamber, and the excess grass and rice straw will be formed into cylindrical briquettes and extruded from the outlet. Then, by returning the delivery end side of each forming roller to the original position where the delivery port was reduced, normal briquette forming work can be performed again.

Example Embodiments of the present invention will be described with reference to the drawings.

1 is a grass and rice straw forming machine, 2 is a pick-up section installed at the front of the machine, and 3 is a forming section installed at the rear of the machine.The pick-up section 2 picks up dried grass and rice straw in the field. The molding section 3 collects the molding material and transports it to the molding section 3, which includes a plurality of molding rollers 4,
4... are arranged on the same circumference to form a briquette forming chamber 5 surrounded by them. 6 is a briquette outlet.

The grass and rice straw forming machine 1 is located at one rear side of the tractor 7 and is towed via a countershaft 10 that is interlocked with a bevel gear 9 installed at the rear end of a power extraction shaft 8 of the tractor 7. The power of the pick-up section 2 and the forming roller 4 is transmitted from the countershaft 10.

In the forming section 3, the plurality of forming rollers 4 forming the briquette forming chamber 5 are each pivotally supported on the drive side by a transmission case 12 by a bearing 11, and a bearing 13 on the briquette delivery side of each forming roller 4 is supported on the transmission case 12 by a bearing 11.
is supported via an eccentric body 14 which is rotatable about the axis. Reference numeral 15 denotes a support cylinder for the eccentric body 14, and the inner circumferential surface of the eccentric body 14 serves as an eccentric portion.
16 is a positioning stopper, and this positioning stopper 16 is connected to the two positioning holes 1 of the eccentric body 14.
It has a protrusion 19 that locks on either of 7 and 18,
It is fixed by a fixing screw 20. The forming roller 4 is in a predetermined position at the position where the positioning hole 17 of the eccentric body 14 is engaged with the protrusion 19 of the positioning stopper 16, and the forming roller 4 is at a position where the positioning hole 18 is engaged with the protrusion 19 of the positioning stopper 16. 4 is deviated outward so that the outlet side of the briquetting chamber 5 can be expanded. A grip portion 20 for turning operation is integrally formed on the end surface of the eccentric body 14. In addition,
The forming roller 4 has a structure in which the outer peripheral surface of a cylindrical body is coated with hard rubber.

In the structure constructed as described above, grass and rice straw transferred from the pick-up section 2 to the forming section 3 are passed between the forming rollers 4 into the briquette forming chamber 5.
The briquettes are then compressed into briquettes by forming rollers 4. The formed briquettes are sequentially delivered from the delivery port 6, cut into predetermined lengths, and released.

If the amount of grass or rice straw supplied to the molding chamber 4 becomes excessive, the density of the briquettes will become abnormally high, making molding and delivery impossible or causing clogging. Then, loosen the fixing screw 20 of the positioning stopper 16, turn the eccentric body 14, and align the positioning hole 18 with the positioning stopper 1.
If it is fixed again at the position where it locks with the protrusion 19 of 6,
Since the briquette forming chamber 5 is expanded toward the outlet 6 side, by continuing the forming operation, the excess grass and rice straw is formed into cylindrical briquettes and pushed out from the outlet 6. I can put it out. After the briquettes are removed from the briquette forming chamber 5, the eccentric body 14 is returned to its original position.
When the protrusion 19 of the positioning stopper 16 is engaged and fixed in the positioning hole 17, the forming roller 4 returns to the predetermined position, and the normal briquette forming operation can be continued thereafter.

Effects of the Invention In short, the present invention provides a grass and rice straw forming machine that rakes and collects grass and rice straw with a pick-up section installed at the front of the machine and transfers it to a forming section at the rear of the machine to form it into briquettes. , in the molding part,
A briquette forming chamber is formed surrounded by a plurality of forming rollers, and the briquette delivery side bearing of each forming roller is supported via an eccentric body that can rotate freely with respect to the axis, making it possible to expand the delivery port of the briquette forming chamber. Because of this structure, even if excessive grass or rice straw is supplied into the briquette forming chamber, which is made up of multiple forming rollers, and the density of the briquette becomes abnormally high, or if clogging occurs, eccentricity will be avoided. By turning the body relative to the axis, the briquette delivery side bearings of each forming roller can be made eccentric and the delivery port of the briquette forming chamber can be widened, allowing excess grass and rice straw to be removed in a circular manner. It can be formed into columnar briquettes and delivered. Therefore, the situation can be resolved without interrupting the work, and the molding work of grass and rice straw can be carried out smoothly and efficiently.
