Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that adds a decomposition accelerator to the cut husk culm when the threshed husk culm is cut with a disk cutter and returned to the field. This invention relates to a method that allows the addition of the decomposition accelerator to be performed more efficiently.

Conventionally, waste culms that have been threshed with a combine harvester are discharged as long culms for various reuse, or they are cut with a cutter and returned to the field to ripen through bacterial decomposition to promote nutrient circulation. I was doing it like that.

In the latter case, it is not only possible to efficiently dispose of the husk, which is an unnecessary waste generated during harvesting, but also to improve soil fertility by decomposing the husk in the field and supplying it as harmless nutrients for growing next year's crops. It has the advantage of being a valuable organic resource for maintenance.

However, in order to decompose and ripen the cut culms, bacterial activity must be active, but this is generally not always sufficient, so there is a drawback that the next cropping regulations come to fruition in an unripe state. there were.

For example, this tendency was observed in areas with high groundwater levels, low temperature areas, areas with insufficient water content, and areas with low oxygen content.

Therefore, in fields in such areas, the culms cannot fully ripen and C/
The problem was that the N ratio was not well balanced, and the growth of parabolites was not smooth or uneven.

The purpose of this invention is to promote and assist the decomposition of bacteria by efficiently adding a decomposition accelerator during the culm shedding process using an extremely simple structure and rational design, in view of the above-mentioned problems associated with field restoration of cut culms. The purpose of the present invention is to provide an excellent waste culm processing device that can perform the following steps.

The structure of the present invention in accordance with the above object is that when the threshed waste culm is fed later in a combine harvester and cut into a predetermined width by a disc cutter, the disc cutter directly adds decomposition promoting additives to the blade part of the disc cutter. The additive is scraped out of the tank to ensure that it is added and adsorbed to the cut surface of the culm, and by uniformly distributing the additive, the decomposition activity of bacteria is uniformly supported, so that the sprayed culm in the field is fully ripened. The gist of this is to ensure that the creation and training can be done evenly.

Next, embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a combine harvester, and a preprocessing section 3, an operating section 4, and a threshing machine 5 are placed on a crawler 2 from the front.

A waste culm processing device 7 is provided at the rear of the threshing machine 5 via a waste culm conveying device 6.

The discharged culm processing device 7 has a structure in which an upper chemical tank 9 is provided between the casings 8, and a disc cutter 10 is provided in the lower part thereof.

The disk cutter 10 has a well-known upper rotary blade 11 and a lower rotary blade 1.2 mounted on rotary shafts 13 and 14 having different relative speeds together with appropriate accessory devices 15 and 16.

17 is a mission.

Each of the upper rotary blades 11 faces into a slit 19 of a supply port provided at the tip of each corresponding protrusion 18 below the drug tank 9, and a decomposition accelerator is applied between the drug tanks 9 as appropriate. It has both a function of scraping out 20 and a damper function.

As shown in FIG. 4, an appropriate feeding load detection device 23 is installed on the rail 22 installed opposite to the conveyance cheno 21 of the threshing machine 5, and is connected to the discharging culm conveyance device 6 to operate the disk cutter 10. The electromagnetic actuating device 26 of the clutch pulley 25 of the drive belt 24 that drives the culm may be connected to an appropriate electromagnetic actuating device 26 by an electric circuit 27, so that the culm processing device 7 is operated only when the culm is ejected.

It goes without saying that the load detection device 23 may be provided in the culm conveyance device 6.

Note that 28 is a chute provided in the casing 8, and serves as a culm guide to the culm conveying device 6 and the disc cutter 10.

In the above configuration, when the combine harvester 1 is operated in a field and crops such as rice are threshed by the threshing machine 5, the load between the conveyance cheno 21 and the rail 22 causes the detection device 23 to relay the electromagnetic actuating device 26 to activate the clutch. The pulley 25 is operated, and the drive belt 24 is rotated to rotate the disc cutter 10.

Therefore, in the process where the threshed waste culm is transferred into the casing 8 by the conveyor 6, transferred from the chute 28 to the disc cutter 10, and cut by the relative rotation of the upper shaft rotation 11 and the lower shaft rotation blade 12, the upper Due to the rotation of the shaft-rotating blade 11, the blade edge is exposed to each slit 19 of the chemical tank 9, so that the stored decomposition accelerator 20 is forcibly scraped out, so that it is uniformly applied to the cut surface of the culm and the cutting frame. Add decomposition accelerator 20.

Therefore, since there is a lot of moisture on the cut surface of the culm, the decomposition accelerator is sufficiently adhered to the cut surface and is evenly dispersed before being dropped onto the field.

Further, since the decomposition accelerator in the chemical tank 9 is forcibly scraped out by the rotating blade, no bridging phenomenon occurs.

When the culm is not supplied to the conveyor chain 21, the clutch pulley 25 is disengaged and the rotation of the rotating disks 11 and 12 is stopped, and the cutting of the culm and the supply of the decomposition accelerator are stopped, but the overspeed process This can be easily solved by manually operating the electromagnetic actuator 26 with a switch.

Although not shown, a dispersion plate, rocking plate, deflection plate, etc. is provided at the bottom of the casing 8 to uniformly disperse the cut culm and the decomposition accelerator, to stir it, and to dissipate the cut culm and the decomposition accelerator. It is possible to drop it off to one side.

As described above, according to the present invention, a chemical tank is provided above the disk cutter provided at the rear of the threshing machine, and the chemical tank is inserted into the chemical tank from the supply port of the chemical tank, so that the disk cutter When cutting the culms, the disc cutter is used to extract the chemical from the tank and attach it directly to the cut surface where there is a lot of moisture, and it can be evenly distributed between the cut culms, so it is not scattered in the field. The cut culm is uniformly dispersed with the decomposition accelerator.

Therefore, in the field, the cut culms are reliably decomposed by bacteria and decomposed to a fully ripe state by the time of the first cultivation.

Since the chemical attached to the cut portion promotes decomposition more reliably, decomposition can be carried out efficiently even at low temperatures and in low water areas.

In addition, since the disc cutter also has the function of a shutter to stop the supply of medicine to the medicine tank, the number of parts is reduced accordingly and the entire apparatus becomes compact, which is an excellent effect.
