Description

A fertilizer deep applicator

technical field

The invention relates to a fertilizer applicator, in particular to a fertilizer deep applicator, which belongs to the technical field of agricultural and forestry machinery.

Background technique

Orchard ditching and fertilization is an important operation process in orchard management. The depth of fertilization is expected to exceed 35 cm and reach about 40 cm. The typical structure of the existing orchard rotary tillage fertilizer applicator can be found in Chinese patent documents such as ZL200720310031.2.

As far as the applicant knows, even if these existing rotary tillage fertilizer applicators are equipped with powerful power, the maximum plowing depth is difficult to exceed 35 cm, and the soil clods splash obviously during rotary tillage, so the fertilization effect is not ideal, and it is more suitable for organic fertilizers with poor fluidity. so it is.

Contents of the invention

The object of the present invention is to propose a deep fertilizer application machine which only needs conventional power to ensure that the depth of organic fertilizer application reaches more than 40 cm, so as to effectively meet the needs of orchard management.

In order to achieve the above object, the fertilizer deep application machine of the present invention includes a frame structure frame dragged behind the walking machine, the front lower part of the frame supports a front horizontal shaft driven by a power device, and a group of The radially extending front rotary cultivators distributed in axial intervals are characterized in that: the rear side of the frame supports a rear horizontal shaft connected to the power unit in transmission, and the hinged hanging end of the rear horizontal shaft supports a rotary shaft. The rocker transmission box of the tiller shaft, the rotary tiller shaft is connected to the rear horizontal shaft by transmission, and the extended end is equipped with a set of axially spaced and radially extended rear rotary shafts that form a subsequent positional relationship with the front rotary tiller The upper middle of the rocker arm transmission box is hinged with the piston rod end of the lifting hydraulic cylinder, the cylinder body of the lifting hydraulic cylinder is hinged with one end of the support rod, and the other end of the support rod is hinged on the machine. on the shelf.

During work, when the walking machine is moving forward, the front rotary tiller is used as the front stage to complete the shallow ditching, and the rear rotary tiller that follows it realizes the shallow ditching due to its position lower than the front rotary tiller. Based on the deep ditching, the digging of the deep ditch can be completed with conventional power, which can effectively meet the needs of orchard management for applying organic fertilizers. And the combination of the rocker transmission box hinged on the rear horizontal shaft and the hydraulic lifting mechanism makes the position of the rear rotary tillage shaft conveniently regulated according to the required ditch depth, so it has good adaptability.

Detailed ways

The fertilizer deep application machine of the present embodiment is named multi-layer horizontal cutting organic fertilizer deep application machine, and its specific structure is shown in Fig. Finally, for example, it can be hung behind a common tractor, and the power is input by means of a six-tooth or eight-tooth transmission shaft of the tractor. The front upper side of the frame 1 is equipped with a power box 2 as a power device, and the front and lower sides of the frame 1 and the middle support arm 1-1 support the front horizontal shaft 3 driven by the power box 2 through internal gear transmission. The side of the front horizontal shaft 3 away from the power box 2 and the middle support arm 1-1 are equipped with a group of axially spaced radially extending front rotary blades 4 (the figure is only for illustration, the specific shape of the rotary blade and The structure can refer to existing technical documents such as ZL200720310031.2), because it has the function of offset rotary tillage operation, the installation number of rotary tiller knives before adjusting the axial distance can adjust the width of the front rotary tillage ditch, the width of rotary tillage in this embodiment Between 0 and 120 cm. The angular misalignment of adjacent front rotary cultivators is 45° (30°-60° range is acceptable).

One side of power box 2 stretches out the output shaft 2-2 that driving sprocket 2-1 is housed, and frame 1 corresponds to the position above the front rotary cultivator 4 and is fixedly connected to the rear frame 1-2 that extends backward and supports One end is equipped with the rear horizontal shaft 5 of the driven sprocket 5-1, and the rear horizontal shaft 5 and the power box 2 form a chain through the chain (not shown) between the driving sprocket 2-1 and the driven sprocket 5-1. Drive connection. The rear horizontal shaft 5 corresponds to the position in the middle of the rear frame 1-2. Transmission connection, its two protruding ends are respectively equipped with a group of axially spaced and radially extending rear rotary blades 8 that form a follow-up positional relationship with the front rotary blades 4, and the adjacent rear rotary blades are also angularly misaligned by 45 ° (30°-60° range is acceptable). The upper middle of the rocker arm transmission box 6 is hinged with the piston rod end of the lifting hydraulic cylinder 9, the cylinder body of the lifting hydraulic cylinder 9 is hinged with one end of the support rod 10, and the other end of the support rod is hinged on the frame 1. Rear frame 1-2 on. Therefore, the rocker arm transmission box can be swung around the rear horizontal axis under the action of the lifting hydraulic cylinder, and the swing angle can be adjusted between the rocker arm transmission box and the ground at an angle of 15° to 60°, so that the rear rotary tiller The depth of entry into the soil varies between 25 and 50 cm, so that based on the depth of entry into the soil of the front rotary tiller, it can be further deepened according to needs, creating good conditions for the fertilization of organic fertilizers and other fertilizers, and with the help of hydraulic lifting control, it can be conveniently met. The need for different fertilization depths.

Tests have proved that the use of the deep fertilizer application machine of this embodiment makes the deep application of horizontal rotary tillage organic fertilizer feasible, and the effect is very significant. Therefore, it solves the problem that the current orchard fertilization cannot be close to the root system of fruit trees, and it is difficult to ensure that the soil and fertilizer are evenly mixed. It has laid a good foundation for the vigorous growth of fruit trees and the improvement of fruit yield and quality. And because of the use of multi-layer relay horizontal rotary tillage, it avoids the sharp increase of resistance caused by the increase of rotary tillage depth for a single rotary tiller in order to achieve deep plowing, and the resulting tool damage phenomenon; and the power source and rotary tillage The offset structure of the mechanism is conducive to applying fertilizer close to the root system of fruit trees, which significantly improves the efficiency of fertilization.
