JPS597391Y2 - Rice husk delivery control device in subsoiler - Google Patents

Description

[Detailed explanation of the invention] This invention uses a blade hanging down in the ground to crush the hardened plowing soil and restore air permeability and water permeability. The rice husk inside the rice grain hopper is sucked up by a blower, and the rice grain is forcibly discharged into the groove that is being formed behind this blade, and the rice husk that has formed in the ground is filled with the rice husk. This device relates to a rice husk delivery control device in a so-called subsoiler that is designed to further improve and maintain air permeability and water permeability depending on the part of the rice husk. The purpose of the present invention is to provide a control device configured to perform interlocking operations to stop the feeding of rice husks so that suction and feeding of rice husks can be carried out smoothly.

Next, the structure of this invention is that the blade body has a rectangular hollow cylindrical tube 2 on the rear edge of the blade body 1, which is a long and thin plate with the upper part centered, and whose width is approximately the same as the horizontal width of the blade body 1. is fixed to form a vibrating blade 3, and a digging body 4 with a scooping surface whose rear part is inclined upward with respect to the direction of movement is attached to the lower end of the blade body 1. The rear plate 2a of 2 has an opening 2bL.

The base of a mounting arm 5 extending forward at a right angle is fixed to the upper part of the blade body 1, and this mounting arm is placed between left and right brackets 7, 7 fixed to frames 6, 6 provided at the front and rear of this subsoiler. 5 is pivotally supported on a horizontal shaft 8, and this mounting arm 5 is swung up and down as described later to vibrate the vibrating blade 3 up and down around the shaft 8. opening 2b
The rice husk is pushed into the plowing platform cut by the excavator 4, and the rice husk hopper 9 for feeding the rice husk into the conduit 2 moves the bottom 9a in the front-rear direction as shown in FIG. It has a boat-bottom shape when viewed from above, and is elongated along the longitudinal direction (front-back direction) of the frames 6, 6.
The vicinity of the bottom 9a of the rice husk hopper 9 is fixed approximately directly above the frames 6 by front and rear brackets attached to the rice husk hopper 6.

A husk collecting auger 10 for collecting rice husks from the front and rear directions is pivotally supported near the top of the guide tube 2 to a husk collecting tube opening 9b provided on the bottom 9a, and a suction tube opening 11a of a blower 11 attached to the bottom 9a is attached. is communicated with the husk collecting pipe opening 9b of the rice husk hopper 9.

The discharge tube opening 12 inserted into the discharge portion 11 b of the blower 11 and the inflow tube opening 13 inserted into the upper end of the conduit tube 2 are connected through a flexible tube 14 .

A horizontal input shaft 15 is provided at the front of the frames 6, 6.
is pivotally supported in the front-rear direction, and a bevel gear 16 attached to the rear of the input shaft 15 is engaged with a bevel gear 18 that rotates as one unit with the drive pulley 17, and between a driven pulley 19 attached to the blower 11 and the drive pulley 17. A belt 20 is wrapped around the belt.

In addition, a belt 23 is wound between the driving pulley 21 attached to the input shaft 15 and the driven pulley 22 attached to the rice collecting auger 10, and if the belt 23 is tensioned by the tension pulley 24, the rice collecting auger 10 can be rotated. Also, this tension pulley 24 can be connected to the belt 23.
A clutch portion 25 is formed so that the rice collecting auger 10 can be stopped by separating it from the clutch portion 25.

One embodiment of this clutch section 25 is shown in FIG. 3, and a piston 26a of a hydraulic cylinder 26 is connected to the tension pulley 24, and a hydraulic pump 28 is connected to this hydraulic cylinder 26 via an electromagnetic switching valve 27. For example, when the electromagnetic solenoid 27a of the electromagnetic switching valve 27 is not energized, the pressure oil of the hydraulic pump 28 causes the piston 26a to protrude against the spring 29, so the tension pulley 24 tensions the belt 23. When this electromagnetic solenoid 27a is energized from the power source 30, the pressure oil of the hydraulic pump 28 works together with the spring 29 to retract the piston 26a, so that the tension force 24 is separated from the belt 23. I am admonishing you.

Also, the suction port 11a of the blower 11 is connected to its opening 31a.
A plate-shaped shutter 31 that can be opened or closed by
When the shutter 31 is closed, the solenoid 27b comes into contact with the operating part of the switch 32 and closes the normally open contact 32a of the switch 32, so that the electromagnetic solenoid 27a is energized.

In the illustrated example, the shutter 31 is connected to a piston 33a of a hydraulic cylinder 33, and a hydraulic pump 35 is connected to this hydraulic cylinder 33 via an electromagnetic switching valve 34. When the electromagnetic solenoid 34a is energized by the closing operation of the normally open contact 37a of the detector 37 that detects clogging of rice husks in the vicinity, the oil passage switching operation of the electromagnetic switching valve 34 is performed and the shutter 3
1 is provided for closing operation.

In addition, in the illustrated example of the structure in which the vibrating blade 3 is oscillated back and forth around the shaft 8, an eccentric portion 15a eccentric to the axis of the input shaft 15 is provided on the input shaft 15. A spherical bushing 38 is fitted into the eccentric portion 15a via a bearing so that it can only rotate freely.

In addition, the middle part of a swinging arm 40 having a rotatable push plate 39 at its rear end is supported by a horizontal shaft 41 to the frames 6, 6 so as to be swingable in the vertical direction. A spherical bushing 42 is fitted to the front part of the arm 40, and a rocking plate 43 is attached to the spherical bushing 38, which is slidable on the fitting surface of the spherical bushing 42 and the spherical bushing 38, respectively. , 42, and a tension spring 45 is stretched between the swing arm 40 and the push plate 39 so that the push plate 39 is always brought into contact with the passive plate 44 attached to the front end of the mounting arm 5. ing.

A hitch pin 47 is attached to the lower part of the mast 46 extending upward from the front ends of the frames 6, 6. 47 protrudes from the left and right, and this hitch pin 47. 47 to a mobile agricultural machine (not shown) and transmits the rotation of the power take-off shaft of the power agricultural machine to the input shaft 15 via the universal joint shaft, the eccentric portion 15 of the input shaft 15
a causes the swinging plate 43 to swing up and down, and therefore the swinging arm 40 also swings up and down around the shaft 41, and the swinging blade 3 swings and vibrates back and forth in the traveling direction around the shaft 8. On the other hand, since the rotating rice collection auger 10 collects the rice husks at the bottom 9a of the rice husk hopper 9 into the collection port 9b, the blower 11 moves the rice husks from the suction port 1
1 Suction of rice husks from a and discharge part 11 by the centrifugal force
The rice husks are sent from b through the flexible pipe 14 into the conduit 2,
Rice husks are discharged into the ground from the opening 2b of the conduit 2 and filled therein.

Since the rice husk delivery control device according to this invention is constructed as described above, the vibrating blade 3 that moves underground while being towed by the power agricultural machine is moved by the swinging plate 4 as the input shaft 15 rotates.
The vertical swing of the blade 3 causes the mounting arm 5 to swing back and forth around the shaft 8 via the swing arm 40, and this small vibration causes the blade body 1 and the digging body 4 to cut the hardened plowing board. This means that it can advance with less forward resistance while being crushed.

When the shutter 31 is open, the input shaft 15
is the drive pulley 21, belt 23 and driven pulley 22
Since the rice collecting auger 10 is rotated through the rice husk hopper 9, the rice husk collecting auger 10 scrapes the rice husks in the rice husk hopper 9 toward the husk collecting cylinder opening 9b, and at the same time, the input shaft 15 rotates through the bevel gears 16 and 18. Drive pulley 17 driven by
Since the blower 11 is rotated by the driven pulley 19, the rice husks at the husks collection tube opening 9b are transferred to the suction tube opening 11 of the blower 11.
The rice husks are sucked into the rice husk and sent out from the discharge part 11b into the conduit 2 through the opening 2b of the conduit 2 into the groove 48 opened by the blade 1 while applying centrifugal force.

and a manual switch 36 for interrupting the work, for example.
When rice husks are thrown in, or when the conduit 2 becomes clogged with rice husks, the shutter 31 moves as described above to cut off communication between the shell collection tube opening 9b and the suction tube opening 11a.

As the shutter 31 closes, the normally open contact 32a of the switch 32 closes the circuit between the electromagnetic solenoid 27a and the power source 30, so that the pressure oil from the hydraulic pump 28 moves the piston 26a toward the hydraulic cylinder 26. When the tension pulley 24 is moved backward, the tension pulley 24 separates from the belt 23, so the belt 24 is relaxed, and the clutch portion 25 is in the disengaged position, and the rice collection auger 10 is stopped. The raking operation towards the shutter 31 is stopped, and as a result, rice husks do not accumulate near the shutter 31 and cause clogging.

In this invention, as mentioned above, the shutter 3
Since the rice collecting auger 10 stops in conjunction with the closing operation of step 1, it is extremely convenient without requiring any human assistance.
