Description

[Detailed Description of the Invention] The present invention relates to an awn removal machine that removes awns, stems, etc. from rice seeds.

Normally, when seed rice is sown with a seedling seeding machine,
If the seed rice has awns, stems, etc. attached to it, it will greatly affect the accuracy of sowing, so the seed rice is put in an awn remover to remove the awns and stems.
Leave the branches, stems, etc.

An awn removal machine has already been devised in which the seeds are pushed through a porous awn removal body using a feeding screw, and the awns and branches separated from the holes in the awn removal body are removed. A structure is adopted in which the ink is removed by wind power.

By the way, seed rice is not only fully mature, but also incomplete (unsuitable for sowing), and it is preferable to use only perfect seeds for sowing. Most incomplete seed rice has less endosperm and is flattened, making it lighter than perfect seed rice.

An object of the present invention is to provide an awn removal machine that can remove incomplete rice along with the awns and ramus by using air for removing the awn and ramus when deseeding seed rice.

The features of the present invention for achieving this purpose are that, in the awning machine for separating the awns and stems from the seed rice, a seed supply port is formed at one end and a discharge port is formed at the other end;
A cylindrical awning body in which a large number of awning holes are formed, and a feeding screw that is arranged concentrically inside the awning body and feeds the rice seeds from the supply port to the discharge port while dehusking the rice seeds. and a seed droplet opening below the discharge port, which receives the awns and stems falling from the awning hole, and surrounds the awning body to form a ventilation path between the awning body and the awning body. an outer cylindrical body, a hopper penetrating the outer cylindrical body and communicating with the supply port;
A suction mechanism is provided at the end of the outer cylindrical body on the side of the supply port and sucks air from the seed dropping port in order to suction the awns and branches that have fallen due to ventilation. The main feature of the present invention is that a wind force adjusting means is provided for adjusting the wind force passing through the seed rice drop opening.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, the awning machine 1 is roughly divided into a cylindrical awning body 2 whose axis is arranged horizontally;
A feeding screw 3 is arranged concentrically within the awn removal body 2, an outer cylinder 4 is arranged concentrically to surround the awn removal body 2, and this outer cylinder 4 is arranged concentrically within the awn removal body 2. A supporting frame 5, a hopper 6 detachably provided on the upper part of the frame 5, and a suction mechanism 7 disposed at the end of the outer cylinder 4 on the seed A supply side.
and a resistance mechanism 8 provided on the front surface of the discharge port of the awn removal body 2.

The awning body 2 is an octagonal punching plate with a large number of holes 11 formed therein, and has a seed supply port 12 on the peripheral surface of one end and a discharge port 13 on the other end. Grooves 14 parallel to the axis of the holes 11 are formed on the inner surface of the deawning body 2, and like the holes 11, they are uneven to allow the awns B and stems C to separate from the seed A. The awning body 2 may be formed of a net, and its cross-sectional shape may be hexagonal, circular, or the like.

The feed screw 3 passes through the inside of the awn removal body 2, and is rotatably supported at one end by the frame 5 via a bearing 16 and at the other end by the outer cylindrical body 6 via a bearing 17, and is connected to a chain transmission means. It is driven by a motor 19 via 18. This feeding screw 3 is constructed by having peristaltic brushes 21 arranged in a spiral shape around a shaft 20.

The peristaltic brush 21 is a synthetic resin brush 21a that is hard enough not to damage the seed rice A, and a grooved metal rod 22.
It is implanted in the groove of the shaft 20, wound spirally around the shaft 20, and welded to the shaft 20. In the axial direction of the shaft 20, coarse parts S and dense parts P are formed alternately.

The seed rice A is quickly sent in a coarse state to the coarse pitch section S, and is sent in a dense state to the dense pitch section P while slowly being pushed against each other. That is, the feeding screw 3 moves the seed rice A in peristaltic motion while
The grains A are moved from the supply port 12 to the discharge port 13, and along the way, the holes 11 and grooves 14 of the dehulling body 2 are removed due to the rubbing of the seeds A against each other due to peristaltic motion.
By locking the awn B and branch stalk C, the awn B and branch stalk C are released. The detached awn B and ramus fall into the outer cylindrical body 6 through the hole 11.

Further, a pushing portion 24 is formed near the discharge port 13 of the feeding screw 3. This pushing part 24
is a shaft 20 with short round rods 25 arranged in a spiral pattern and welded to the shaft 20, which resists the resistance force of the resistance mechanism 8 and
Push it strongly.

The outer cylindrical body 4 supports the awn removal body 2 via support members 28 and 29, and the end close to the supply port 12 is open facing the suction mechanism 7, and the end close to the discharge port 13 is open. A dropping port 30 for the seed rice A is formed on the lower surface. A ventilation passage 3 is provided between the outer cylinder body 4 and the awning body 2.
1 is formed, and the air sucked from the drop port 30 by the suction mechanism 7 passes through the ventilation path 31 and collects the awns B and ramus C that have fallen into the outer cylinder 4 below the suction mechanism 7. The dust is discharged from the dust outlet 33 to the dust collecting basket 34. This dust collection basket 34 is formed of a fine mesh net.

A cap 35 is provided at the drop port 30 of the outer cylinder 4, and an air suction path 36 is formed by the cap 35. Seed rice A falling from the drop port 30
Some of them are incompletely matured, and they have less endosperm and are lighter than fully matured ones, so they are blown into the ventilation path 31 by the levitation force of the air passing through the air suction path 36, that is, by the wind force. and is removed to the dust collecting basket 34 together with the awn B and the branch stem C.

Reference numeral 37 denotes a wind force adjustment means provided on the upper part of the outer cylinder 4, and is configured to open and close an air intake port 38 formed in the outer cylinder 4 with an adjustment lid 39, and this adjustment lid 39 has two A book groove 39a is formed, and 2
A thumbscrew 40 passes through the groove 39a and is screwed into the outer cylinder 4. Tightening and loosening the thumbscrew 40 adjusts the position of the adjustment lid 39 to change the size of the air intake port 38. By doing so, the amount of air taken into the ventilation passage 31 is adjusted.

If the amount of air flowing in from the air intake port 38 is large, the amount of air suctioned from the drop port 30 will be reduced, and the wind power will be reduced, so that only particularly light among the immature seed rice will be removed. Conversely, the air intake port 3
If the amount of air flowing in from 8 is small, use the drop port 30.
The amount of air sucked in increases, the wind force is large, and relatively heavy immature seed rice is also removed.

In this way, the drop opening 3 can be adjusted simply by adjusting the adjustment lid 39.
The wind force of 0 can be adjusted, and the size of immature seed rice to be separated from fully mature seed rice can be set extremely easily.

Reference numeral 60 denotes a cleaning opening formed in the lower part of the outer cylinder 4, which is opened and closed by a lid 62 provided on the outer cylinder 4 via a hinge 61.

The hopper 6 is fitted into the upper part of the frame 5, is removably fixed with a bolt 43, penetrates the outer cylinder 4, communicates with the supply port 12, and dehusks the seed A in fixed amounts. Supplied into the body 2.

The suction mechanism 7 includes a fan 45 fixed to the shaft 20 of the feeding screw 3 and a cover body 47 surrounding the fan 45 and forming a suction chamber 46. The cover body 47 is attached to the frame 5. It is fixed, communicates with the outer cylindrical body 4, and is connected to its end.

The resistance mechanism 8 includes a spring 5 in front of the discharge port 13.
A disc-shaped resistor 51 which is compressed by 0 is arranged to provide resistance to the seed rice A discharged from the discharge port 13.
This is to increase the sliding contact and pushing movement of the seed rice A in the deawning body 2 to more completely deawn the seeds.

According to the present invention described in detail above, a suction mechanism is provided to remove the awns and awns that fall into the outer cylinder, and air is sucked from the drop opening of the outer cylinder below the outlet of the awn removing body. , it is possible to separate and exclude incompletely mature seed rice from the seed rice after awning, and the size of the incomplete seed rice to be separated can be selected by the wind adjustment means, so that only fully mature seeds can be easily and reliably removed. It is easy to select and adjust the selection.
