BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to dehulling of seed rice and improvement of a branch and stem device.

[0002]

2. Description of the Related Art A threshing and dried seed rice is put into a hopper, and a stirrer provided in the hopper is forcibly stirred to remove awns and branches.
Japanese Patent Application Laid-Open No. 56-124308), a device for demarching and branching a seed rice in a hopper with a stirring rod that rotates at a high speed (for example, see Japanese Utility Model Application Laid-Open No. 59-86241), or a vent hole. There is an apparatus (e.g., see Japanese Utility Model Publication No. 3-9796) in which a screw carrier is provided in a cylinder having a horizontal posture, and the screw carrier transports seeds to remove and branch.

[0003]

SUMMARY OF THE INVENTION The above-mentioned prior art demarcation and branching means is based on the effect of demarcation and branching by a stirring means composed of a rigid metal such as a spiral body, a stirring rod, a cylinder and a screw. However, since this method is severe, there is a serious problem that good seed rice is damaged and damaged, and paddy rice is frequently generated.

[0004] In addition, in the prior art, since there is no means for selecting dehulled rice and good seed rice, the dehulled rice is sown and raised as seed rice, but this dehulled rice does not germinate. As described above, the occurrence of a lack of seeds at the stage of raising seedlings directly affects rice planting, and there is a problem that a lot of time and labor are required for supplementary planting in the missing parts.

An object of the present invention is to provide a seed rice with a natural and irregular rotating motion in a state of being wrapped in both flexible and elastic action panels, and to achieve a degrading efficiency by soft touch demarcation and branching. The purpose is to improve the quality and prevent the generation of paddy rice.

[0006]

Means for Solving the Problems The structure of the present invention for solving the problems of the prior art is to have a seed pad supply port at the top and a substantially horizontal posture operation panel having moderate flexibility and elasticity. A working plate made of the same material opposed to the other through a required gap; both working plates or one of the working plates is rotatable; and both or one of the surfaces of the working plate Is provided with a layer having wear resistance.

[0007]

[Action] Seed paddles that are induced and sandwiched between the two operation panels by the action of centrifugal force are wrapped between the two operation panels by the flexible elasticity of the operation panel, and are given an irregular rotational motion. During the period from the release to the release, efficient detouching and branch stalk processing of soft touch without dehulling occur. In addition, the wear-resistant layer attached to the surface of the operation panel improves demarcation and branching efficiency, prevents wear of the operation panel, prolongs the life of the operation panel, reduces the frequency of replacement, and reduces work efficiency. Improvement can be achieved.

The present invention can be applied to some of the operation panels 25 and 28 shown in the first embodiment.

[0038]

According to the configuration of the present invention as described above, the following effects can be obtained. (a) The seed rice that is guided and sandwiched between the two operation panels by centrifugal force is wrapped between the operation panels by the soft elasticity of the both operation panels, and irregular rotation is given in this state.
Until the water is released from the outside of the working panel, reasonable soft-touch degumming and branch stalk processing are performed efficiently. The efficiency of sowing and raising seedlings without plants and the efficiency of rice transplanting with a rice transplanter without supplemental planting can be improved. (b) The wear-resistant layer attached to the surface of the operation panel can improve demarcation and branching efficiency, prevent wear of the operation panel, prolong the life of the operation panel, and work less frequently. Efficiency can be improved. In particular, when the rotating action plate is formed of a sponge material, the efficiency of demarcation and branch spike is good, but by adding a layer to this, a more effective demarching and branch branch effect can be obtained.
