Description

The fertile adjustable seed and fertilizer-expelling unit in cave

Technical field

The utility model belongs to agricultural machinery, relates generally to seeding, fertilizer parts on a kind of seeding and fertilizing facility.

Background technology

It is that agricultural goes up the most widely used agricultural method at present that the sowing of dry crop is finished synchronously with the fertilising operation, and fertilization mode adopts row application more, its shortcoming is that chemical fertilizer loss, waste are bigger, crops its root system in process of growth can't absorb partly chemical fertilizer at all, especially to bunch planting crops such as the bigger white melon of spacing in the rows, corns, row replacement is more outstanding to the problem of chemical fertilizer loss and waste, has improved production cost.For realizing spreading manuer in holes fertile operation, reduce the chemical fertilizer loss and waste, reduce production costs, the fertile mechanical research of spreading manuer in holes begins to attract much attention, such as on distributing roller cylindrical peripheral surface, being provided with fertile hole structure or adopting the drawplate type scheme such as fertile structure of spreading manuer in holes to come out one after another, but in produce using,, fail to be applied because of spreading manuer in holes fertile of poor quality or complex structure, the reasons such as fertile action is unreliable, fault is more, the accuracy of applying fertilizer difference of spreading manuer in holes.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, and design provides a kind of cave fertile adjustable seed and fertilizer-expelling unit, reaches the purpose that realizes that chemical fertilizer is spreaded manuer in holes, reduced the chemical fertilizer loss and waste, improves chemical fertilizer utilization ratio, reduces production costs.

Basic design of the present utility model is, installs the fertile wheel of spreading manuer in holes on the seed manure axle that is positioned at position, seeding roller both sides respectively, and two is spreaded manuer in holes, and fertile wheel is whole to lay respectively in the left and right fertile chamber of housing, is laid with on the fertile wheel outer circumference surface of spreading manuer in holes and fills fertile groove; Measure being sleeved on the seed manure axle that adjustment disks can endwisely slip, circumferencial direction is located at two fertilizer that are provided with fertilizing amount adjusting boss in cave on the side end face, and lay respectively at the fertile wheel of spreading manuer in holes of left and right side outside left, its cave fertilizing amount is regulated boss and is filled fertile groove and contact cooperation; Two declutch shift shaft assemblies are installed on housing sidewall, the shift fork difference inserting of two declutch shift shaft assembly inner ends is in the circular groove of the fertilizer amount adjustment disk outer end of left and right side, adjust drive link for two and be packed in respectively on the declutch shift shaft assembly outer end of both sides, screw is adjusted in the hinge installation on adjusting drive link; The axial limiting seat is fitted on the housing sidewall outside, and the two-way adjustment screw rod that the both sides thread rotary orientation is opposite is fitted in the axial limiting seat strip hole, and axial location; The adjustment screw spinning of and arranged on left and right sides is on two-way adjustment screw rod both sides.

The utility model has been realized the chemical fertilizer operation of spreading manuer in holes, and seeding and fertilizer are finished synchronously, fertile the concentrating in cave imposes on the seed both sides, fertile amount evenly, the cave fertilizing amount can be regulated according to producing needs, utilization rate of fertilizer can reach more than 80%, and the characteristics that this utensil has is simple in structure, easy to adjust, operation is reliable, operation quality good, economize on fertilizer, utilization rate of fertilizer is high are particularly suited for the bigger crop fertilization of spacing in the rows such as white melon, corn, sunflower, kidney bean and use.
