Semi-automatic fertilizer applicator for trees

Abstract

The invention relates to a tree semi-automatic fertilizing machine used at the root of fruit three. The invention is formed by a movable element and a stable element, wherein, the movable element comprises a material barrel with fixed handle, a digging duck bill, and a discharger whose material inlet is connected to the bottom of barrel and the material outlet is opposite to the upper end of duck bill; the stable element comprises a base plate fixed with a pedal for driving the movable element downwards. The base plate is mounted with two tracks, while the track sheath fixed on the movable element is sliding engaged with two tracks. The movable and stable elements are connected with drawing spring. One end of output drawing rod is connected to the stable element while another end is connected to the material barrel in the discharger to roll the barrel. The duck bill is switched by the torsion spring, and the fixed top rod controls the opening degree. The invention can be operated by human while the duck bill and discharger are both controlled by the connecting rod to realize linkage and improve working efficiency.

Description

Technical field: [0001] The invention relates to an agricultural and forestry plant protection appliance, in particular to an underground fertilizer applicator suitable for the roots of fruit trees, and can also be used for seeding. Background technique: [0002] Existing manual sowing and fertilizing device, as described in Chinese patent 03211367 "portable fertilizing and seeding device", includes a solid-packed bucket, a handle and a hole-opening duck under the bucket, the feeding port of the discharger and the feeder. The bottom interface of the bucket, the discharge port of the discharger is directly opposite to the upper port of the hole-opening duck, and the transmission body with a rack is placed in the outer shell of the seed box, and the rack meshes with the teeth of the cylindrical adjusting part, and the rack moves up and down. The adjuster is rotated forward and reverse, and the slide plate is connected with the seed and fat duck mouth through the pull rod. Pre...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure is complex, the operation is error-prone, and the production cost is high;

[0004] 2. The duckbill enters the soil entirely by hand. For places with hard soil, the labor intensity is high, and it cannot even penetrate to the required depth;

[0005] 3. It is troublesome to adjust the amount of discharge and the depth of entry into the soil
