JPS597395Y2 - Rice husk filling device in subsoiler - Google Patents

Description

[Detailed explanation of the invention] This invention uses a blade suspended underground to crush hardened plowing soil and restore air permeability and water permeability.
The rice husks in the rice husk hopper are sucked up by a blower, and the rice husks are forcibly discharged from the introduction tube installed at the rear of the blade into the groove that the blade is opening. The present invention relates to a rice husk filling device for a subsoiler, which further improves and maintains air permeability and water permeability by using a rice husk filling section filled with rice husks.

Since rice husks generally tend to contain moisture, they tend to clog the inlet tube and the blower discharge tube opening.For example, when the subsoiler is temporarily stopped, the discharge of rice husks from the inlet tube to the groove also stops, so the blower The actual situation is that rice husks become strongly clogged near the outlet of the discharge tube, requiring troublesome work to remove them.

Therefore, this invention is proposed to solve this problem, and its structure will be explained based on an example applied to a subsoiler in which the blade body swings back and forth in the direction of movement with its upper part as the center as shown in the figure. Then, the elongated plate-shaped blade body 1
An upward-sloping digging body 2 is attached to the lower part of the machine, an introduction tube 3 having an opening at the lower end and an opening at the upper end is fixed to the rear edge of the blade body 1, and a mounting arm 4 is fixed to the upper part of the blade body 1. By pivoting the base of this mounting arm 4 to frames 5, 5 provided at the front and rear with a horizontal shaft 6, the blade body 1 is shaped so as to be swingable in the front and rear directions around the shaft 6. ing.

On the other hand, a rice collection cylinder opening 7b is provided on the boat-shaped bottom 7a of the rice husk hopper 7 attached to the frames 5, 5, and a suction part 8a of a blower 8 attached to this bottom 7a is communicated with the rice collection cylinder opening 7b. The discharge tube opening 8b of the blower 8 and the upper end of the introduction tube 3 are connected to a flexible tube 9.
The rice husks collected at the rice collection tube mouth 7b by the rice collection auger 10, which is connected to the rice husk hopper 7 and extended inside the bottom 4a of the rice husk hopper 7, are passed through the blower 8.
The rice husks are suctioned from the suction portion 8a of the blower 8 and subjected to centrifugal force, and sent to the introduction tube 3 from the discharge tube port 8b via the flexible tube 9 along with the air sucked in from the intake port 8C of the blower 8. Opening 3a to groove 11 being opened by cylinder 3
The rice husks are discharged together with exhaust air and filled to form a rice husk filling part 12 in the ground.

Therefore, in this invention, as shown in FIGS. 2 and 3, a part of the outlet 8b of the blower 8 is cut out to form a narrow outlet 8d.
An exit door 13 is provided, which can block the exit 8d.
are screwed to the discharge cylinder opening 8b with a hinge 14 so as to be freely openable and closable, and the weights 16a, 16b... are attached to the locking pins 17 to brackets 15.15 and 15.15 protruding from the outer surface of the exit door 13. A weight 1 that is removably locked and located on the opposite side of the door 13 across the vertical line H from the hinge 14.
6 a , 16 b . . . , the drain door 13 is installed to close the drain outlet 8 d, and the blower 8 discharges the rice husks without any abnormalities, thereby preventing clogging of the rice husks in the discharge tube opening 8 b or the introduction pipe 3. If there is no exit door 13 as described above.
However, if the introduction pipe 3 or the discharge pipe opening 8b is clogged with rice husks, the discharge pressure of the blower 8 will become excessive, and this excessive discharge pressure will cause the discharge pipe 13 to continue to be closed. is pushed open as shown in Figure 4 and exits 8d.
The structure is designed so that excess rice husks leak out from the rice husks.

In addition, instead of the above-mentioned weight 16a, a leaf spring 18 as shown in FIG. 5 or a torque spring (not shown) is used to ensure that the overflow door 13 always closes over the overflow exit 8d. It may be structured as follows.

In addition, as a means for rocking and vibrating the blade 1 in the front-back direction,
An input shaft 19 having an eccentric portion 19a eccentric to the rotational axis is supported by the frames 5, 5, and the eccentric portion 19a
A push plate 2 at the rear end of a swinging arm 22 into which a spherical bushing 20 is fitted so as to rotate freely, and whose middle portion is pivotally supported by a horizontal shaft 21.
A spherical bushing 2 is fitted to the front part of the swinging arm 22, and the spherical bushing 2 is fitted in the front part of the swinging arm 22.
5 and a swing plate 26 fitted onto the spherical bushing 20.
is shaped so that it can swing with respect to these two spherical bushes 20 and 25, respectively, and the input shaft 19 is rotationally driven by the PTO shaft of the power agricultural machine to which this subsoiler is connected. Since the eccentric portion 19a causes the swing plate 26 and the front part of the swing arm 22 to swing up and down, the blade body 1 also swings back and forth about the shaft 6.

Also, a bevel gear 28 that meshes with a bevel gear 27 attached to the rear end of this input shaft 19 is provided, and this bevel gear 28 and 1
A belt 31 is wound around a driving pulley 29 provided on the body and a driven pulley 30 attached to the blower 8.

A belt 34 is wound between a driving pulley 32 attached to the input shaft 19 and a driven pulley 33 attached to the rice collecting auger 10.

Since the rice husk filling device according to this invention is constructed as described above, the blade 1, which is towed by a power agricultural machine and moves underground, is moved vertically by the vertical swing of the swing plate 26 as the input shaft 19 rotates. As a result, the blade body 1 and the excavating body 2 move forward while crushing the hardened plowing platform. , a groove 11 is opened at the rear of the blade body 1 and the introduction tube 3.

Further, since the rotation of the input shaft 19 rotates the rice collection auger 10, the rice husks in the rice husk hopper 7 are fed into the rice collection cylinder opening 7b, and at the same time, the blower 8 also rotates and the rice husks are collected at the rice collection cylinder opening 7b. Some rice husks are sucked into the blower 8 from the suction part 8a, and the rice husks to which centrifugal force has been applied are transferred from the discharge pipe opening 8b to the introduction pipe 3.
and is discharged from the opening 3a into the groove 11 and filled therein.

When the rice husks are discharged by the blower 8 without any abnormality and there is no clogging of rice husks in the discharge tube opening 8b or the introduction tube 3, the weight 16a as shown in the example shown in FIG.
Due to the action of ..., the drain door 13 remains closed to the drain outlet 8d, but when the introduction tube 3 or the discharge tube opening 8b is clogged with rice husks, the discharge pressure of the blower 8 becomes excessive and the draining occurs. The door 13 is pushed open, and as a result, excess rice husks are discharged from the narrow outlet 8d to the outside of the discharge tube opening 8b.

Therefore, when the rice husks become clogged in this way, they are automatically discharged from the discharge pipe port 8b, so even when the subsoiler is stopped at 1 o'clock, for example, the excess rice husks are discharged to the ground. This avoids the inconvenience of the blower 8 forcibly continuing to rotate in an overloaded state, and allows the rice husk filling operation to continue smoothly.
