Description

  The present invention relates to a powder application device for a seeding machine, and is intended to perform accurate and smooth seeding by sucking and removing dust generated from fertilizer to be applied and seed powder.

  A technique (see, for example, Patent Document 1) of a sowing machine (direct sowing machine) that includes a fertilizer application device and a sowing device and sows on a paddy soil surface or the like is known.

JP 2010-193773 A

  In the direct seeder, seeds having a coating agent on the outer peripheral surface are often used. Fertilizer hoppers and sowing hoppers often generate dust due to fine chipping of fertilizer particles or peeling off of the seed coating agent, and these dust accumulates in each fertilizer hopper or sowing hopper and becomes a lump. Then, there are problems that the fertilizer grains and seed grains adhere to this lump and become difficult to move out, and adhere to the inner surface of the hopper and obstruct fertilization and sowing operations.

  According to the first aspect of the present invention, the engine 2 is mounted in the engine cover 1, and the powder particles accommodated in the fertilization hopper 6 and the sowing hopper 7 by the rotation of the feeding rolls 4, 5 at the rear part of the vehicle body 3 that is driven. In the sowing machine that attaches the fertilizer 9 and applies the fertilizer sowing to the traveling soil surface, and in the fertilizer hopper 6 and the sowing hopper 7, It is set as the structure of the powder agent application apparatus of a seeder provided with the dust collection cylinders 10 and 11 which attract the dust inside the hoppers 6 and 7.

  When performing the sowing work by the sowing machine, the fertilizer for fertilization is accommodated in the fertilizer hopper 6, and the seed is accommodated in the sowing hopper 7. While the seeding device 8 is lowered by the forward traveling of the vehicle body 3 and is pushed closer to the soil surface and propelled, the seeds fed by the rotation of the feeding roll 5 of the seeding device 8 are sown in the grooves formed on the soil surface.

  Further, the fertilizer fed by the rotation of the feeding roll 4 of the fertilizer application is applied to the soil surface near the sowing position. In the fertilizer application device 9 and the seeding device 8, dust collection cylinders 10 and 11 are connected to the fertilization hopper 6 and the seeding hopper 7, and dust in the fertilization hopper 6 and the seeding hopper 7 pass through the dust collection cylinders 10 and 11. Dust generated inside is sucked out.

  For this reason, the fertilizer and seeds fed by the feed roll 4 of each fertilizer application device 9 and the feed roll 5 of the seeding device 8 reduce the amount of dust, and eliminate moisture absorption by the flow of suction air from the dust suction cylinders 10 and 11. Then, it is maintained in a dry state, and the adhesiveness between fertilizers or seeds to be applied is reduced, and the dispersibility is maintained, thereby allowing accurate and smooth fertilization and sowing.

  According to the second aspect of the present invention, the fertilizer hopper 6 and the sowing hopper 7 are directed to the dust collection cylinders 10 and 11 through the fertilizer hopper 6 and the sowing hopper 7 while sucking hot air from the engine room in the engine cover 1. It makes it attract | suck, It is set as the powder agent application apparatus of the seeder of Claim 1 characterized by the above-mentioned.

  As described above, the fertilizer hopper 6 and the sowing hopper 7 suck and exclude dust generated by the suction air generated by the dust suction cylinders 10 and 11, but suck and supply the fertilizer hopper 6 and the sowing hopper 7 from the engine room connected to the fertilizer hopper 6 and the sowing hopper 7. Dust is absorbed while being heated by the heated air.

  For this reason, the adhesion supply between the fertilizers and seeds in the fertilizer hopper 6 and the sowing hopper 7 by the feeding rolls 4 and 5 is prevented, and the feeding by the feeding rolls 4 and 5 is performed smoothly.

  Invention of Claim 3 attracts and guides the hot air which passed the radiator 12 of the said engine 2 to the fertilization hopper 6 or the sowing hopper 7, The granule of the seeding machine of Claim 1 or 2 characterized by the above-mentioned. Application equipment.

  The hot air guided from the engine room is sucked and supplied to the fertilizer hopper 6 and the sowing hopper 7 as hot air sucked through the radiator 12. The hot air that has passed through the radiator 12 absorbs the heat in the radiator 12 and is dried, so that the dryness of the powder in each fertilizer hopper 6 and the sowing hopper 7 is appropriately maintained and effectively maintained. Heating and drying can be carried out for accurate and smooth feeding.

  In the invention described in claim 1, in the fertilizer hopper 6 that accommodates fertilizer and seeds made of a granule, and in the sowing hopper 7, dust suction cylinders 10 and 11 are used to suck in dust. From the fertilizer hopper 6 and the sowing hopper 7, fine dust generated in the sowing hopper 7 can be sucked and removed to the outside, and the fertilizer and seeds can be dehumidified and maintained in a dry state. Accurate fertilization and sowing can be carried out by smoothly applying fertilizers and seeds, and applying and transporting the fertilizer and seeding hoses and sowing hoses.

  According to the second aspect of the present invention, the dust removing action that is sucked out from the fertilizer hopper 6 and the sowing hopper 7 as described above causes the hot air in the engine room generated by driving of the engine 2 to the fertilizer hopper 6 and the sowing hopper 7. Since the fertilizer and seeds in the hoppers 6 and 7 are heated and sucked by this hot air while sucking and guiding, the drying effect of the fertilizer and seeds is enhanced, and accurate and smooth feeding sowing is performed. It is possible to simplify the configuration.

  According to the third aspect of the present invention, the hot air sucked into the fertilizer hopper 6 and the sowing hopper 7 as described above sucks and guides the radiator air heat exchanged through the radiator 12 of the engine 2, Since the fertilizer and seeds are heat-dried, the heat-drying of these fertilizers and seeds can be effectively maintained, so that accurate and smooth feeding application can be performed, and the hot air through the radiator 12 is used. Therefore, the configuration can be simplified and effective drying can be performed.
