Description

[Detailed description of the invention] [Industrial application field] This invention relates to the field of sowing machines used when sowing seeds in agriculture.

[Prior Art] A hopper that is supported and moved by front and rear wheels is provided, a swinging frame whose front end is pivoted to the front wheel shaft is disposed below the hopper, and a feeding roller for row seeding is installed in the swinging frame. is arranged, and the front wheel shaft and the feeding roller are configured to rotate in conjunction with each other via a belt,
A row seeding machine is already known which is constructed so that seeds in a hopper are successively dropped downward by the rotation of a feed roller in the hopper, and are sown in rows by a feed roller for row seeding. In this conventionally known method, the feed roller for row seeding was made of synthetic resin or aluminum.

[Problems to be solved by the invention] In the conventional method, seeds that fell between the row sowing feed-out roller and the inner wall of the swinging frame were stuck between the row-sowing feed-out roller and the swinging frame inner wall. In such a situation, the feed roller for row seeding sometimes stopped moving.

This invention was made to solve such problems.

[Means for solving problems] This will be explained with reference to the drawings.

The feeding roller 5 of the seeding machine according to this invention is
A hopper 1 that is supported and moved by front and rear wheels 3 and 4 is provided, a swinging frame 16 whose front end is pivoted to a front wheel shaft 14 is arranged below the hopper 1, and a row-seeding feeder is disposed within the swinging frame 16. A roller 15 is disposed, and the front wheel shaft 14 and the row sowing feed-out roller 15 are configured to rotate in conjunction with each other via the belt 8, and the seeds 13 in the hopper 1 are successively dropped downward by the rotation of the in-hopper feed-out roller 5. In the seed sowing machine configured to sow the seeds in rows with the feed-out roller 16 for row-sowing, the feed-out roller main body 11
is made of a polymeric material, and a slippery smooth layer 12 is provided on the seed contact surface of the feed roller main body 11 for row sowing.

[Example] The explanation will be based on the drawings.

1 is a hopper, 2 and 2 are support plates fixed to both left and right sides of the hopper 1, 3 and 4 are front wheels and rear wheels that are pivotally connected to the support plate 2, and 5 is a feeder for internal use in the hopper that is pivotally supported within the hopper 1. Roller, 14 is front wheel axle, 1
6 is a swinging frame whose front end is pivoted to the front wheel shaft 14;
6 is a drive pulley provided on the front wheel 3; 7 is a passive pulley provided on the row sowing feed roller 15;
8 is a V-belt stretched between the drive pulley 6 and the passive pulley 7, and 9 is a seedling box.

10 is a central shaft made of a steel rod, 11 is a main body of a feed-out roller for row seeding made of a polymeric material fixed around the central shaft 10, and 12 is a slippery smooth layer attached to the surface of the main body 11 of the feed-out roller.

In addition, 17 is a drive pulley that is fitted and fixed to the front wheel shaft 14, 18 is a driven pulley that is fitted and fixed to the shaft of the inner hopper feeding roller 5, and 19 is a driven pulley that is fitted and fixed to the front wheel shaft 14.
are drive pulley 17 and driven pulley 18
It is an endless belt stretched between the

The hard polymer material constituting the feed roller body is preferably hard natural rubber or synthetic rubber.
Further, the smooth layer can be formed by applying an adhesive to the rubber surface and drying it, and then applying a lacquer and drying it.

[Operation] When the seed rice 13 is put into the hopper 1 and the front wheels 3 and rear wheels 4 are moved along the seedling growing box 9, the row sowing feed-out roller 15 is rotated via the drive pulley 6, V-belt 8, and passive pulley 7. Hopper 1
Seed rice 13 that has fallen from the ground is sown downward via a feed-out roller 15 for row sowing.

At this time, since the surface of the row sowing delivery roller 15 has a smooth and slippery layer, the seeds can slide smoothly between the row sowing delivery roller 15, which prevents the seeds from forming clumps and allows for smooth seed delivery. During this process, the row feed roller can be rotated.

[Effect of the invention] In the conventional type of feed-out roller for row sowing made of a polymer material that does not have a smooth layer on the surface, seeds, especially rice seeds, form a lump between the feed-out roller and the surrounding wall and become clogged. There were times when the machine stopped rotating. If the row seeding feed-out roller does not rotate, the wheels connected via the V-belt will also not rotate. In other words, the seeding machine will stop. For this reason, it was necessary to loosen the seeds in the swing frame each time.

In addition, there are some that use special measures to prevent seed clogging as much as possible, but the measures are elaborate.

However, in this invention, the method is simple because a smooth layer is simply provided on the surface of the feed-out roller for row sowing made of polymer material, and slipping occurs between the feed-out roller for row sowing and the seeds, resulting in seed clogging. This makes it possible to maintain smooth rotation of the feed roller for row sowing.
