Abstract

The utility model provides an offset rotary cultivator for orchard, pertaining to the art of gardening machinery. The utility model consists of a power part, a plowing part and a suspending part; the power part includes a front universal joint, a transmission shaft, a rear universal joint, a differential mechanism and a half shaft connected with a rear power output shaft of a wheeled tractor in turn; the half shaft is jacketed with a half-shaft bushing and a bearing bushing mutually connected; one end of the half-shaft bushing is connected with the shell of the differential mechanism; the external end cavity of the bearing bushing is provided with a bearing and the bearing is arranged on the half shaft. The plowing part consists of a rotary cutter arranged on a rotary cutter bushing and the rotary cutter bushing is arranged on the half shaft. The suspending part consists of a V-shaped frame and a horizontal connecting frame respectively arranged on the half-shaft bushing on both sides of the shell of the differential mechanism; the upper end of the V-shaped frame is movably connected with a center bracket at the rear of the tractor; the external end of the horizontal connecting frame is movably connected with a hydraulic frame at the rear of the tractor respectively through an upper suspending frame and a lower suspending frame. The rotary cultivator can complete the rotary cultivation, fertilization, loosening and weeding of the ground at the roots of fruit trees at one time, thus reducing the labor intensity and increasing the work efficiency.

Description

The orchard offset ratory cultivator

1, technical field:

Orchard of the present utility model belongs to the graden machine field with offset ratory cultivator.

2, background technology:

Upright arbor fruit trees such as the apple tree that grows up in to the orchard, pear tree applies fertilizer, loosens the soil, during weeding, because tree crown is short and be thick with leaves, common rotovator can't be near tree root, can only be by people's handwork around tree root of arching one's back, labour intensity is big and work efficiency is low, has also increased planting cost.

3, summary of the invention:

The purpose of this utility model is to provide a kind of orchard offset ratory cultivator that can implement the rotary tillage operation to fruit tree roots such as apple tree, pear trees.

The purpose of this utility model is achieved in that offset ratory cultivator is made up of power, farming and suspension three parts, power section is made up of the preceding universal joint, power transmission shaft, rear universal joint, differential mechanism, the semiaxis that are linked in sequence with the wheel tractor rear power output shaft, be with continuous semiaxis sleeve and bearing sleeve on the semiaxis, semiaxis sleeve one end links to each other with differential casing, be equiped with bearing in the chamber, outer end of bearing sleeve, be enclosed within on the semiaxis; The farming part is formed by even being contained in the cutter group of revolving of revolving on the broach shell tube, revolves the broach shell jacket casing and is contained on the semiaxis; Suspended portion is made up of the herringbone frame and the horizontal link that are installed on the semiaxis sleeve of differential casing both sides, active linking to each other of center bearing bracket behind the upper end of herringbone frame and the wheel tractor, the outer end of horizontal link is respectively by active the linking to each other of hydraulic pressure frame behind upper and lower hanger bracket and the wheel tractor.

Owing to adopt technique scheme, wheel tractor is traveling on two vacant lots of arranging between apple trees or pear tree, this rotovator is under its traction, the revolving the cutter group and can carry out the rotary tillage operation of biasing to the ground of fruit tree root, apply fertilizer, loosen the soil, weeding once finishes, both reduce labour intensity, improved work efficiency again.

5, embodiment:

Embodiment: as shown in Figure 1, offset ratory cultivator is made up of power, farming and suspension three parts, and power section is made up of the preceding universal joint 12, power transmission shaft 13, rear universal joint 14, differential mechanism 15, the semiaxis 4 that are linked in sequence with the wheel tractor rear power output shaft.Be with continuous semiaxis sleeve 6 and bearing sleeve 5 on the semiaxis 4, semiaxis sleeve 6 one ends link to each other with the housing of differential mechanism 15, are equiped with bearing in the chamber, outer end of bearing sleeve 5, are enclosed within on the semiaxis 4.Farming part is contained in the cutter group of revolving of revolving on the broach shell tube 17 and forms by connecting, and this revolves the cutter group and revolves revolving tool rest 1, be installed in the cutter 2 that revolves that revolves in the tool rest 1 and form on the broach shell tube 17 by connecting to be contained in, and revolves tool rest 1 and all is intervally arranged in the longitudinal and transverse direction of revolving broach shell tube 17.Be equiped with key 16 on the semiaxis 4 at bearing sleeve 5 outer ends places, have narrow orifice revolving on the inner barrel of broach shell tube 17, revolve broach shell tube 17 and be sleeved on the semiaxis 4, narrow orifice is stuck on the key 16, and narrow orifice is sheathed with positioning sleeve 3 outward.Suspended portion is made up of the herringbone frame 9 and the horizontal link 7 that are installed on the differential mechanism 15 housing both sides semiaxis sleeves 6, active linking to each other of center bearing bracket behind the upper end of herringbone frame 9 and the wheel tractor, the outer end of horizontal link 7 is respectively by active the linking to each other of hydraulic pressure frame behind upper and

lower hanger bracket

10,11 and the wheel tractor.Above-mentioned forward and backward

universal joint

12,14, power transmission shaft 13, differential mechanism 15, semiaxis 4 all can adopt 212 jeep vehicle component.

During operation, wheel tractor is traveling on the vacant lots between two row apple trees or pear trees, and this rotovator is under its traction, and revolving the cutter group and can implementing the rotary tillage operation to the ground of a side fruit tree root of biasing loosened the soil, weeding, fertilising once finish.
