Description

[Detailed explanation of the idea] The present invention relates to an air jettison type switch.

The above-mentioned aerial dumping type cutting machine is a machine used for ripening humus (soil humus) using various agricultural and forestry waste materials and livestock manure as raw materials.

The method for ripening humus described above is currently under separate patent application (application number 5).
3-139855), the above raw materials are stirred at appropriate time intervals, blown up into the air while controlling the temperature, and deposited in a well-ventilated state to promote ripening.

As mentioned above, as a means of blowing humus raw materials into the air,
At the time of completion of the above invention, a dedicated band tractor type machine was used, but the inventor of the present invention subsequently made efforts to improve the above invention, and as a result, as shown in Fig. 1, a machine with a driver on board was used. We have devised an air jettison type cutter 1 that can be equipped as an attachment to a tractor 2.

The air dumping type cutting machine shown in FIG. A right-handed scraping screw 5 is fixedly attached to the right half of the body.

6 is a transmission means for the rotating shaft 3, which will be described later with reference to FIG. 2, 7 is a blower device, which will be described later with reference to FIG. 2, and 8 is a chute attached to the blower device.

This type of air dumping type switcher can receive power from the large tractor 2, so it can have a large capacity, and the operator can work while sitting in the driver's seat of the tractor. It has the advantage of requiring less physical stress.

This air jettison type switcher is supported by a tractor 2 and works while moving in the direction of arrow A.

Hereinafter, the direction of arrow A will be referred to as the front, and the direction opposite to arrow A will be referred to as the rear.

FIG. 2 is a horizontal sectional view of the main body of the above-mentioned cutting machine.

The rotation of the input shaft 9 driven by the PTO of the tractor is transmitted to the sprocket 12 of the transmission means 6 via the bevel gear 10.11, and further to the rotary shaft 3 and the scraper fixed thereto via the chino 13 and sprocket 14. Rotate the screws 4 and 5 in the direction of arrow B.

This direction of rotation is the same as the rotation of the wheels when the tractor 2 travels in the direction of the arrow, and is faster than the rotation of the wheels.

The housing 16 of the blower device 7 is fixed to the turning machine body 1 so as to be located near the center of the rotating shaft 3 and at the rear thereof, and is open toward the rotating shaft 3.

The tip of the input shaft 9 mentioned above protrudes into the blower housing 16, and a blower propeller 17 is fixed thereto.

In order to spray the humus raw material into the air while stirring it using the aerial dumping type cutter machine configured as described above, the rotary shaft 3
And while rotating the impeller 17, move the tractor 2 in the direction of arrow A.
The scraping scoops 4 and 5 are pushed toward the humus material pile.

Then, due to the action of the scraping screws 4 and 5,
The raw material for humus is scraped up to the center as shown by arrows c and c', and sucked into the blower device 7 as shown by arrow E.
Shoot 8 blows up like this.

As a result, the humus raw materials are stirred and redeposited in a well-ventilated state to promote ripening. However, the cutting machine shown in Figure 1 described above has the following defects. As raw materials for the humus, which is not yet perfect, a mixture of sawdust, chip waste, planer waste, straw, fir, wheat bark, fallen leaves, dried grass, etc., and livestock manure is used, and although the composition is not constant, there are many types of humus. In some cases, it contains vegetable fibers such as straw and dried grass.

Therefore, when the scraping screw 4 is pushed into the accumulated raw material, the raw material in the left end section 4a to F area of the left-handed screw type scraping screw 4 is scraped in the direction of arrow C (see Fig. 2). When trying to remove it, the raw material in the six areas on the side also tries to be pulled in the direction of arrow G due to the entanglement of the fibers.

When the cutting machine body moves forward in the direction of arrow A in this state, the front surface of the chain cover 15 of the transmission means 6 gets caught in the raw material.

The raw material in zone 1 is difficult to separate due to the entanglement of fibers with the raw material in zone 6, making it impossible for the cutter body to move forward.

As mentioned above, in order to solve the problem that the air dumping type turning machine is blocked by the accumulation of raw materials and is prevented from moving forward, the transmission means of the rotating shaft 3 is not provided at the shaft end, and the sprocket 14 is installed as shown in the phantom line 18. An attempt was also made to provide the transmission means in the center of the rotating shaft 3 as shown in FIG.
Also, the wire wound around the wire is caught on a transmission means such as a chain case (both not shown) surrounding the wire, resulting in a problem that the wire is not sucked into the blower device 7.

In addition, although it is milder than the transmission means 6, there is also a problem in that the area around the bearing 23 of the rotary shaft 3 is attached to the raw material and prevents the smooth forward movement of the cutter.

The present invention was made in view of the above circumstances; the object is to provide an air-dumping type cutter that does not have the risk of being blocked by raw materials and being blocked from moving forward.

In order to achieve the above object, the present invention fixes scraping screws with different feed directions to the left and right halves of a horizontally installed rotating shaft, and In an air jettison type switcher comprising a transmission means for driving a rotary shaft and a blower device at the rear near the center of the rotary shaft, at least one end of the rotary shaft is connected to a bearing of the rotary shaft or the transmission means. It is characterized in that it protrudes, and a disc-shaped side cutter is fixed to the protruding end.

Next, an embodiment of the present invention will be described with reference to FIG.

The shaft end of the rotating shaft 3 on the side to which the sprocket 14 is fixed is extended to the left, penetrates the chain cover 15, and is made to protrude to the left.

A disk-shaped side cutter 19 is fixed to the protruding end of the rotating shaft.

20 is a side cutter mounting nut.

FIG. 4 is a perspective view of the side cutter.

The circumference is a cutting edge. In this example, the circumferential portion 21
The cutting blade has a shape similar to a circular saw blade, but the shape of the cutting blade can be set arbitrarily.

The disc-shaped side cutter in the present invention has a circumferential cutting blade and a mounting means integrally formed in the center thereof (in this example, a rotating shaft mounting hole 22 having a protrusion that fits into a keyway).
It is a member equipped with.

As shown in FIG. 5, the aerial dumping type cutter equipped with the side cutter configured as described above moves in the direction of the arrow a while rotating together with the rotating shaft 3 as the side cutter 19 advances into the material in the direction of the arrow A. Proceed along the line and cut the raw material.

Therefore, the raw material in one area near the advancing direction of the chain cover 15 of the transmission means 6 is separated from the raw material in six areas on the side thereof.

Therefore, the scraping screw 4 removes the raw material in one area by the arrow C.
The raw materials in the 6 areas do not move from their original positions even if they are scraped in the same direction.

In this way, near the front of the transmission means 6, the arrow a
Without moving the raw materials to the left of the line, move the arrow acr)
The raw material on the right side of the cotton is scraped up by the scraping screw 4, and the raw material on the path of the chain cover 15 of the transmission means 6 is removed.

As shown in FIG. 5, if the front surface of the chain cover 15 is sloped so that the outer side of the chain cover 15 protrudes more forward than the inner side, the raw material near one area will be removed from the chain cover 15.
This is convenient because it is scraped off by the screw 4 while sliding inward without being pulled.

FIG. 6 shows an embodiment different from the above.

The difference from the above embodiment is that side cutters 19 and 19 are attached to both ends of the rotating shaft 3, respectively.

In this way, the same effect as described above is obtained on the left side where the transmission means 6 is provided, and also on the right side where the transmission means is not provided, there is no possibility that the raw material will be drawn to the bearing 23 of the rotating shaft 3. The operation of the turning machine becomes even smoother.

As described above, the effect of making the operation of the turning machine smoother by attaching the side cutter 19 to the end of the rotating shaft on the side where the drive means 6 is not provided is as follows. Drive sprocket 18 in the center
It can also be applied to a type of cutting machine equipped with.

As explained above, in the present invention, at least one end of the rotating shaft is made to protrude beyond the bearing of the rotating shaft or the transmission means thereof, and a disc-shaped side cutter is fixed to the protruding end. This has an excellent practical effect in that it eliminates the risk of getting stuck in the raw material and being blocked from moving forward.
