Description

[Detailed explanation of the invention] This invention crushes the hardened plowing soil by moving the blade suspended underground while vibrating back and forth, restoring air permeability and water permeability. A vibrating subsoiler that improves and maintains both ventilation and water permeability by filling the ground with rice husks at the rear.
This invention relates to a rice husk hopper for storing rice husks in a rice husk, and aims to provide a rice husk hopper that allows rice husks to smoothly flow from the rice husk hopper into a blower for sending the rice husks underground. be.

Next, the configuration of this invention will be explained based on one embodiment shown in the drawings.A blade part 1a is provided on the front edge of a blade 1 in the form of a long and thin plate. A rectangular hollow cylindrical conductor 2 with the same width is fixed to form a vibrating blade 3, and the rear plate 2a of the conductor 2 is opened 2b over the range where the conductor 2 hangs down and sinks into the ground. A digging body 4 is attached to the lower end of the blade body 1 and has a scooping surface whose rear part is inclined upward with respect to the direction of movement.

The base of a mounting arm 5 extending forward and approximately at right angles is fixed to the upper part of the blade body 1, and the left and right brackets 7.7 are fixed to frames 6.6 provided at the front and rear of the vibrating subsoiler as shown in the figure. This mounting arm 5 is supported by a horizontal shaft 8,
By swinging this mounting arm 5 up and down as described later, the vibrating blade 3
is vibrated up and down around the shaft 8, and at the same time this conductor 2
The rice husk hopper 9 for feeding the rice husks into the conduit 2 has a bottom portion as shown in FIG. 9a has a boat bottom shape when viewed from the front and rear directions, and is long in the longitudinal direction (front and rear direction) of the frame 6.6.
Front and rear brackets 10a attached to frame 6.6
, 10b, the vicinity of the bottom 9a of the rice husk hopper 9 is fixed approximately directly above the frame 6.6, so that the weight of the rice husk hopper 9 and the weight of the rice husks stored therein are loaded approximately equally on the left and right sides of the frame 6.6. to be done.

A screw 11 is pivotally supported in the bottom 9a for collecting rice husks from the front and rear directions to a grain collection tube opening 9b provided on the bottom 9a near the top of the conduit 2, and one side of the bottom 9a near the grain collection tube opening 9b. A mountain-shaped recess 9C is provided in the side plate when viewed from the side as shown in FIG. 1, and by inserting the upper part of the blower cover 13 of the blower 12 into the recess 9C, the screw 11 can be extended as shown in FIG. The blower 12 is formed as close as possible to the side, and the suction port 13a of the pro cover 13 is communicated with the grain collection port 9b of the rice husk hopper 9.

Air suction holes 13b are provided on the outer side plate of the blower cover 13.
A flexible tube 16 connects a discharge tube opening 14 inserted into the discharge section 13C and an inflow tube opening 15 inserted into the upper end of the conduit tube 2.

A horizontal input shaft 17 is provided at the front of the frame 6.6.
is pivotally supported in the front-rear direction, and a bevel gear 18 attached to the rear part of the input shaft 17 meshes with a bevel gear 20 that rotates as one unit with the drive pulley 19, and between the driven pulley 21 attached to the blower 12 and the drive pulley 19. A belt 22 is wrapped around it.

Also, another drive pulley 2 attached to this input shaft 17
3 rotates a driven pulley 25 fixed to the screw 11 via a belt 24.

In the illustrated example of the structure for rocking and vibrating the vibrating blade 3 back and forth around the shaft 8, the input shaft 17 is provided with a disk-shaped eccentric portion 17a eccentric to the axis of the input shaft 17. A roller 26 is fitted into this eccentric portion 17a via a bearing so that it can only rotate freely.

Also, a swinging arm 28 has a push plate 27 rotatably attached to its rear end.
The middle part is supported on the frame 6.6 by a horizontal shaft 29 so as to be able to swing vertically, and a roller 30 is fitted into the front part of the swinging arm 28.
A rocking plate 31 that is slidable on the fitting surface is fitted onto each of the rollers 26 and 30, and a pushing plate is attached to a passive plate 32 attached to the front end of the mounting arm 5. A tension spring 33 is stretched between the swinging arm 28 and the pushing plate 27 so that the swinging arm 28 and the pushing plate 27 are always brought into contact with each other.

Then, the hit pin 35 at the lower part of the mast 34 extending upward from the front end of the frame 6.6 is connected to a mobile agricultural machine (not shown), and the rotation of the power output shaft of the power agricultural machine is controlled by the input shaft 17 via the universal joint shaft. If the transmission is transmitted to the eccentric portion 17 of the input shaft 17
a causes the swing plate 31 to swing up and down, and therefore the swing arm 28 also swings up and down around the shaft 29, causing the vibration blade 3
oscillates back and forth in the traveling direction around the shaft 8, and the rotation of the blower 12 forces the rice husks in the rice husk hopper 9 into the conduit 2, and the rice husks are sent to the ground through the opening 2b of the conduit 2. It is designed to be released into the air.

Since the rice husk hopper according to this invention is constructed as described above, the vibrating blade 3 that moves forward underground while being towed by the power agricultural machine is caused by the vertical swinging of the swinging plate 31 as the input shaft 17 rotates. It will oscillate back and forth around the shaft 8 together with the mounting arm 5 via the oscillating arm 28, and at this time, the blade portion 1a that vibrates little by little will cut through the hardened plowing board and cut into the blade 1.
In addition, the excavating body 4 crushes nearby plowing plates.

In addition, the rice husks collected by the rotation of the screw 11 at the grain collection tube opening 9b are removed by the rotating blower 12.
air suction hole 13b... the blower cover 13
In order to suck an appropriate amount of air into the interior, the rice husks always smoothly flow into the suction tube opening 13a of the proa cover 13, and the rice husks, which are energized by centrifugal force due to swirling, flow from the discharge section 13C to the conduit tube 2.
The conductor tube 2 is fed into the interior and vibrates in small increments in the front-rear direction.
Flows smoothly inside.

The rice husks are continuously released into the ground from the opening 2b at the rear of the conduit 2 that is immersed in the ground, and the rice husks are continuously released into the ground through the opening 2b at the rear of the conduit 2 that is immersed in the ground. The rice husks are filled in the top and bottom of the platform, and the rice husks vibrate in small increments in the front and rear directions.When the rice husks are discharged from the opening 2b, the rice husks are repeatedly pushed into the rear plowing platform by the front plate 2C of the guide 2. Therefore, a properly compacted rice husk filling part is formed behind the vibrating blade 3, and this rice husk filling part can maintain drainage and ventilation performance for a long time.

As mentioned above, the boat-shaped bottom 9 of the rice husk hopper 9
Since a recess 9C is provided in the recess 9C and the upper part of the blower 12 is inserted into the recess 9C, the blower 12 can be very close to the side of the screw 11 that scrapes the rice husks from the front and back of the bottom 9a. Ta.

As a result, the grain collection tube opening 9b on the side of the rice husk hopper 9 and the suction tube opening 13a on the side of the blower cover 13 can both be communicated with each other in an extremely short length, so that the rice husks collected in this way can smoothly flow into the blower 12. This allows rice husks, which tend to absorb moisture and deteriorate fluidity during storage, to be fed into the blower 12 without congestion, and the blower 12 in the illustrated example directs air from outside the rice husk hopper 9 to the air suction hole 13b.・・・・・・
Since the rice husks can be sucked into the blower cover 13 from the rice husks, even in the initial stage of work when the rice husk hopper 9 is full of rice husks, a certain amount of rice husks always flows into the blower 12, and the rice husks can be sucked into the tiller. Inside, a rice husk-filled portion can be formed which is compacted to an appropriate hardness with a suitable amount of rice husk.
