1 is an overall view of a pulverizing and scraping apparatus according to an embodiment of the present invention. It is a side view of the rotating shaft of FIG. It is a top view of the rotating shaft of FIG. 1 is an overall view showing an embodiment of the present invention in which a self-propelled vehicle is a tractor.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a self-propelled vehicle, and the self-propelled vehicle 1 is a walking type management machine. Specifically, 101 is a front wheel, 102 is a drive wheel, 103 is an engine, and 105 is a rotary cover. In the figure, the rotating shaft 203 is provided at the bottom of the machine body located between the front wheel 101 and the drive wheel 102. The drive wheel 102 and the rotation shaft 203 are rotated by the power of the engine 103, and the rotation direction of the rotation shaft 203 is opposite to the rotation direction of the drive wheel 102 as indicated by the arrow. The operator pulverizes the green manure crops and the like in the field with the hammer cutter 202 of the pulverizing and scraping device 2 while advancing the self-propelled vehicle 1, and simultaneously cultivates the soil with the cultivating claws 201. At this time, the soil, green manure crops and the like are agitated and swallowed in the rotary cover 105. The soil is discharged rearward from the rotary cover 105.

  As shown in FIG. 2, a plurality of hammer cutters 202 are attached at equal intervals around the axis of the rotary shaft 203 with a predetermined phase difference, and a plurality of hammer cutters 202 are sandwiched between the rotary shafts 203 on the opposite side. Attach the tilling claw 201 of the above. The hammer cutter 202 has a known structure in which a bifurcated flail is swingably supported. Similarly, the plurality of tilling claws 201 are attached at equal intervals around the axis of the rotation shaft 203 with a predetermined phase difference.

  The tilling claw 201 and the hammer cutter 202 are attached as a pair on the rotary shaft 203 at positions opposite to each other by 180 degrees across the shaft. In FIG. 2, the hammer cutters 202 are attached with a phase difference of 120 °. Specifically, a pair of tilling claws 201a and hammer cutters 202a are attached to the first row at positions opposite to each other by 180 degrees across the shaft and in the same straight line. In the second row, a pair of tilling claws 201b and a hammer cutter 202b are attached in the same straight line with a phase difference of 120 ° from the first row. Similarly, a pair of tilling claws 201c and a hammer cutter 202c are attached to the third row. By providing the phase difference in this way, each hammer cutter 202 and each tilling claw 201 can be arranged closely on the rotating shaft 203 without being overlapped, so that the stirring effect is enhanced and green manure crops etc. Evenly and uniformly. Further, the hammer cutters 202 are arranged close to each other, so that the pulverization effect is enhanced, and the rotation shaft 203 can be prevented from being entangled with green manure crops and the like.

  Specifically, when the hammer cutters 202 are deployed with a phase difference of 120 °, the pair of tilling claws 201 and the hammer cutter 202 are regularly deployed on the rotating shaft 203 with three repeating units. In that case, as shown in FIG. 2, the hammer cutter 202 is regularly mounted on the rotary shaft 203 with a phase difference of 60 ° with the tilling claw 201 in a side view. In this way, if the tiller claws 201 and the hammer cutter 202 are arranged so that the intervals between the tilling claws 201 and the hammer cutters 202 are equal in phase, the balance of the center of gravity during rotation of the rotary shaft 203 is good. Thereby, the stable rotational drive can be performed. Note that the phase difference provided between the hammer cutters 202 or between the tilling claws 201 is not limited to 120 °. For example, any integer in which the hammer cutter 202 or the tilling claw 201 is regularly arranged on the rotation shaft 203 can be selected, such as 30 °, 60 °, and 180 °.

  Here, if the rotational speed of the rotating shaft 203 is too fast, the energy efficiency is lowered, and if it is too slow, the effect of grinding by the hammer cutter 202 is not exhibited. For this reason, it is necessary to maintain an appropriate rotation speed in order to prevent a decrease in energy efficiency while exhibiting the effect of pulverization. For example, in order to exert the effect of pulverization, a rotation speed of about 1000 rotations per minute is desirable.

  At this rotational speed, the phase difference between the hammer cutters 202 is preferably 120 °, and the pair of tilling claws 201 and the hammer cutter 202 are rotated regularly with three repeating units as shown in FIG. If it arrange | positions on the axis | shaft 203, it can scrape in efficiently by the three tilling claws 201 deployed with a phase difference while exhibiting the crushing effect.

  The cutting blade rotation outer periphery circle 204 is a locus drawn by the tip of each hammer cutter 202 at the time of rotation driving. The tilling claw rotation outer circumference circle 205 is a trajectory drawn by the tip of each tilling claw 201 during rotation driving. As shown in FIG. 2, the tilling claw rotation outer circumference circle 205 is configured to be larger than the cutting blade rotation outer circumference circle 204, so that the blade of the hammer cutter 202 suitably cuts green manure crops and the like on the ground surface. The blade enters the ground, and an appropriate tillage depth is secured.

  The arrows in FIG. 2 indicate the rotation direction of the rotation shaft 203. The rotation direction is preferably the reverse direction to the forward direction of the self-propelled vehicle, that is, the reverse direction to the rotation direction of the drive wheels 102. By configuring in this way, the rotation of the self-propelled vehicle 1 in the direction opposite to the forward direction and the tilling claws 201 cut deep into the ground, the soil is well agitated and the green manure crops crushed by the hammer cutter 202 are good. I'm in love.

  FIG. 3 shows the hammer cutters 202 arranged with a phase difference of 120 ° and mounted so as to be symmetric at the center of the rotating shaft 203. As shown in FIG. 3, the hammer cutter 202 and the tilling claw 201 are attached to form a pair in the same straight line, and each pair is attached on the rotating shaft 203 with a phase difference, so that the hammer cutter 202 and the tilling blade 201 are attached. Since they can be closely arranged on the rotating shaft 203 without colliding with each other, a high agitation effect of ground green manure crops and the like and soil can be obtained. And if it attaches so that it may become symmetrical in the center of the rotating shaft 203, the balance of the gravity center of the self-propelled vehicle 1 is also good.

  Further, the tip of the tilling claw 201 is bent to the left or right, and is located near the tip of the adjacent hammer cutter 202. By configuring in this way, the cutting edges of the tilling claws 201 and the hammer cutter 202 become denser, and the cut green manure crops and the like are wrapped in the cultivated soil without missing, so that the green manure crops and the like are well swallowed. Can do.

  FIG. 4 shows a self-propelled vehicle 1 as a tractor. The rotary shaft 203 is attached as a rotary cultivator 401 provided at the rear of the tractor. The rotary cultivator 401 is connected to the tractor via a link mechanism. The rotary tiller 401 is connected to a PTO shaft 402 that transmits engine power. Thereby, the rotating shaft 203 is rotated by the power of the engine. In the present invention, the tilling claw 201 and the hammer cutter 202 are arranged on the rotating shaft 203 in regular repeating units, and therefore the length of the rotating shaft 203 can be arbitrarily determined. Therefore, the rotating shaft 203 can be widely attached from a small vehicle such as a walking management machine to a large vehicle such as a tractor. Therefore, if a tractor is employed in the self-propelled vehicle 1, the range in which the crushing operation and the scavenging operation can be performed at the same time is significantly expanded as the rotating shaft 203 can be configured longer than the walking type management machine. Thereby, even in a vast field, the crushing operation and the plowing operation can be performed efficiently.
