Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a fertilizing device combined with a rotary tiller. Background Art

[0002] With the improvement of agricultural production mechanization and the popularization of agricultural scientific planting technology, large and medium power tractors and supporting agricultural machinery, micro and small agricultural tillage machinery have been widely promoted and used. However, existing agricultural tillage machinery generally has the disadvantages of one machine for one purpose and single function, which leads to low farmland work efficiency and increases the cost of agricultural machinery investment for farmers. Therefore, fertilization devices are often equipped on rotary tillers for collaborative operation.

[0003] The structure of the fertilization device currently installed on the rotary tiller is relatively simple. It only uses a motor to drive the material box to rotate in the material trough to achieve quantitative discharge of fertilizer. However, the outflowing fertilizer can only fall on the soil surface naturally by gravity. Part of the fertilizer will be exposed to the air, resulting in the loss of fertilizer efficiency and unable to fully act on the soil. The practicality is poor. Utility Model Content

When it moves up, the pusher block is pushed up in the fertilizer pile by the sliding rod. At this time, a part of the fertilizer falls into the outlet pipe through the fixed pipe.

[0029] Reference Figure 3 As shown, a stabilizing sleeve 14 is provided inside the fixed tube 8 and is sleeved on the sliding rod 12, and the stabilizing sleeve 14 is connected to the inner wall of the fixed tube 8 through a connecting rod, so that the pusher block 13 can be more stable when moving up and down in the fixed tube 8, so that the pusher block 13 can stably enter and exit the fixed tube 8.
