Description

Technical Field

[0001] The present invention relates to the technical field of furrowing and sowing machinery, and more specifically, to a furrowing depth-controllable grain furrowing and sowing machine. Background Art

[0002] The object of planting by the seeder is the seeds of crops or the coated seeds made into pellets. According to the sowing method, it can be divided into three categories: vacuum seed seeder spreader, row seeder and hole seeder. At present, with the improvement of agricultural mechanization, large tractors are used for sowing. However, due to the deep ruts caused by the driving of the tractor in front or the unevenness of the land itself, the depth of the traditional seeder cannot be adjusted according to the height of the land, resulting in different depths of sowing. Some seeds are sown very deeply, and some are sown very shallowly, resulting in a lower germination rate and inconsistent germination time.

[0003] For example, utility model patent CN206564784U discloses a grain precision uniform sowing seeder, which is provided with a sealing cover on the grain seed bin and the grain fertilizer bin, a seeding device is provided under the driven wheel, the driven wheel is connected to the seeding furrow opener assembly through a conveying pipe, a front furrow opener and a rear furrow opener are provided on the seeding furrow opener assembly, a sowing and fertilizing wheel is provided behind the front furrow opener and the rear furrow opener, a discharge port is provided on the left half wheel, a storage bin is connected to the discharge port on the left half wheel, a storage bin is connected to the feeding pipe on the right half wheel, a limit rod is provided on the seeding furrow opener assembly, a depth adjustment device is provided next to the limit rod and connected to the seeding furrow opener assembly, a ridge-building shovel is provided at the front end of the machine body, a ground wheel is provided at the middle end, a soil covering plate is provided at the rear end, and a pressing wheel is provided behind the soil covering plate. The utility model is easy to operate and improves grain yield;

[0004] However, the above-mentioned patent document only has the function of digging furrows at the sowing position. In actual application, since the prior art does not have an adjusting structure for the furrowing mechanism, and cannot avoid the influence of the high and low ground encountered by the roller when moving during the furrowing process, that is, the ups and downs of the roller during the movement cause the furrowing mechanism to be unable to maintain a uniform furrowing height, resulting in a situation where the furrowing depth cannot be unified. At the same time, there is also a lack of a cleaning structure for the furrowing area before furrowing, which will affect the efficiency of furrowing due to debris in front of the furrowing, resulting in adverse effects on the furrowing and sowing of grains.
