Description

Finger-clamp ejection type precision dibbler

Technical Field

The utility model relates to a precision dibbler in the field of agricultural machinery, in particular to a finger-clamp ejection type precision dibbler.

Background

With the continuous development of agricultural technology and the great popularization of mechanized seeding, the requirement on indexes of the hill-drop planter in agricultural production is higher and higher. In the existing dibbler, when the dibbler needs to work continuously in a large area, in order to rob farm, the sowing speed is greatly increased, the seed taking speed is increased, a large amount of phenomena of missing sowing and multicast are caused, and new requirements are provided for the matching precision requirement of the parts of the dibbler. The existing mechanical dibbler has high requirement on the specification of seeds, can not effectively take seeds when the seeds are overlarge, undersize or irregularly shaped, and causes serious miss-seeding phenomenon, and the seeds are easily adhered to a seed taking part to cause multicast, or the seeds are not easily fallen off from the seed taking part and can not conveniently enter a seed discharging port to cause miss-seeding.

Moreover, the existing seed dibblers are poor in universality, each type of dibblers can only sow seeds at a preset interval, and the planting distance cannot be adjusted, so that the utilization rate of the dibblers is reduced. Patent document CN105850306B discloses a shunting type seed taking device, in which a rotating shaft controlled by a torsion spring is arranged in a seed discharging box, a rotating arm fixedly connected to the rotating shaft is matched with a cam, a pressing block is fixedly arranged on the rotating shaft extending out of the seed discharging box, the pressing block with a clamping curved surface is matched with the inner circumferential surface of a seed guiding groove, and the seed taking device is arranged on the seed discharging box. Although the seed metering device disclosed in this patent document can adjust the row spacing, in the actual sowing operation, the structure of clamping the seeds formed by the matching of the pressing block controlled by the torsion spring and the inner circumference of the seed guide groove cannot stably clamp the seeds, and cannot adapt to the improvement of the sowing speed and the increase of the sowing strength, thereby causing the missed sowing in a large area. Moreover, when the seed taking structure rotates at a high speed in the seed sowing plate, the pressing block is contacted with the side wall of the seed sowing plate to clamp the seeds, so that a large amount of seeds are stirred to be gathered in the fixed plate and then enter the seed sowing port to cause multicast, which is intolerable for a precision type hill planter. In addition, the hill planter disclosed in the above patent document is provided with a plurality of seed taking boxes and connecting blocks, the seed taking boxes and the connecting blocks are not tightly connected, and the formed hill planter structure is easy to deform in the using process, so that the planting precision is reduced.
