The utility model relates to components of agricultural machinery, in particular to a multi-tooth hoe blade of a hoeing robot. The multi-tooth hoe blade of the hoeing robot comprises a hoe blade handle (1), a hoe blade arm (2), a hoe blade plate (3) and hoe blade teeth (4). The hoe blade handle (1) is connected with a power output device, and the upper end of the hoe blade arm (2) is fixedly connected with the hoe blade handle (1). The hoe blade plate (3) is C-shaped, and a rotating central axis of the hoe blade plate (3) penetrates through an opening center of the hoe blade plate (3). The hoe blade arm (2) is parallel to the rotating central axis of the hoe blade plate (3) and fixedly connected with the outer edge of the hoe blade plate (3). The lower surface of the hoe blade plate (3) is welded with a plurality of hoe blade teeth (4) which are distributed on the edge of the hoe blade plate (3). The multi-tooth hoe blade of the hoeing robot has the advantages of being simple in structure, high in hoeing efficiency and the like, and therefore the feature of strong practicality is prominent. The hoeing robot controls rotational motion of a disc type hoe so that hoeing and seedling avoiding can be achieved.

Description

A kind of multiple tooth tine of the robot that hoes up weeds

Technical field

The utility model relates to the multiple tooth tine of a kind of agricultural machinery parts, particularly a kind of robot that hoes up weeds.

Background technology

Traditional method of weed control is by artificial weeding or chemical weed control.The artificial weeding workload is big, efficient is low; The chemical weed control meeting brings threat for ecotope, agricultural product edible safety and health etc.Weeding by machine can increase substantially operating efficiency when abandoning chemical weed control, so weeding by machine begins to be subjected to increasing attention.

Weeds are difficult points of weeding by machine between strain, not only require the intelligent degree height of weeding equipment, and the design of end effector is had higher requirement.

Usually, crop seedling will water after transplanting immediately, one to two week back weeding for the first time.This moment, the top layer, soil was hardened more serious.When using the operation of collar plate shape tine, usually start the earth piece that upper soll layer hardens, damage taking root still shallow seedling easily, and the weeds on the earth piece to be safe and sound, the effect of hoeing up weeds significantly reduces.

Summary of the invention

The purpose of this utility model provides a kind of multiple tooth tine of simple in structure, a kind of robot that hoes up weeds that weeding ratio is high.

The purpose of this utility model is achieved through the following technical solutions:

A kind of multiple tooth tine of the robot that hoes up weeds, it comprises tine handle 1, tine arm 2, tine dish 3, tine tooth 4, wherein:

Described tine handle 1 is connected with power take-off;

Fixedly connected with described tine handle 1 in the upper end of described tine arm 2;

Described tine dish 3 is " C " type, and the pivot axis of tine dish 3 is by the tine dish 3 gap centers of circle, and tine arm 2 is parallel to the pivot axis of tine dish 3 and fixedlys connected with the outer rim of tine dish 3;

The lower surface of tine dish 3 is fixedly connected with a plurality of tine teeth 4.

Described a plurality of tine tooth 4 is distributed in the edge of tine dish 3.

The beneficial effects of the utility model are:

The utility model in conjunction with the design of traditional farm implements of hoeing up weeds, carries out architecture advances based on the disc tine of existing band gap, and is simple in structure, is easy to processing, with low cost;

The utility model is hindered seedling when using the disc tine to hoe up weeds operation at the soil that hardens, the problem of the poor effect of hoeing up weeds, the action of " shovel " changes " rake " into during with its work, can effectively abolish soil compaction, eliminates weeds, and make loosing soil ventilative, remedied above-mentioned defective;

The utility model on the forms of motion except with hoeing up weeds robot along the rectilinear motion that is parallel to the crop row direction, have only unidirectional rotatablely moving, be easy to realize automatic control.The weeds of part that its knife face skims over all will be removed by rake, and the efficient height is practical.

The multiple tooth tine of a kind of robot that hoes up weeds of the present utility model has highlighted stronger practicality with simple in structure, weeding ratio advantages of higher.Hoe up weeds robot by controlling rotatablely moving of collar plate shape tine, can realize hoeing up weeds and keeping away seedling.

Embodiment

The utility model is hindered seedling when using the disc tine to hoe up weeds operation at the soil that hardens, the problem of the poor effect of hoeing up weeds, design in conjunction with traditional farm implements of hoeing up weeds, its structure is improved, when not changing its motion mode, solved problems of the prior art.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.

As shown in Figure 1, 2, a kind of multiple tooth tine of the robot that hoes up weeds comprises tine handle 1, tine arm 2, tine dish 3, tine tooth 4.

Tine handle 1 can be connected on the power take-off (as hydraulic motor, motor) by bolt.(for example, passing through welding manner) fixedlyed connected in the upper end of tine arm 2 with tine handle 1; Tine dish 3 is " C " type, and the pivot axis of tine dish 3 is by the tine dish 3 gap centers of circle, and tine arm 2 is parallel to the pivot axis of tine dish 3 and fixedlys connected (for example, passing through welding manner) with the outer rim of tine dish 3; The lower surface of tine dish 3 is fixedly connected with a plurality of tine teeth 4, is used for loosening the soil and hoeing up weeds; A plurality of tine teeth 4 are distributed in the edge of tine dish 3, and its quantity and spacing can carry out discrepant design according to harden degree and the soil property of different soils.

The course of work of the present utility model:

During work, a kind of multiple tooth tine of the robot that hoes up weeds is installed on the power take-off (as hydraulic motor, motor), advances along the direction that is parallel to crop row, shown in Fig. 3,4, tine tooth 4 inserts in the soil, and embedded depth rationally arranges according to the operation needs.Tine dish 3 is more than ground.Multiple tooth tine is around being parallel to tine arm 2 and the rotation of the axis by the tine dish 3 gap centers of circle.Tine pivot axis departs from crop row center one distance, d 2, to reduce the injury to crop root.Because the tine arm departs from pivot axis one distance, d 1 of tine, the tine arm is unlikely damage stem of plant, leaf in rotary course.Power take-off drives multiple tooth tine advances along being parallel to the crop row direction, when moving to the crop position, and multiple tooth tine Rotate 180 degree, the gap of tine dish 3 is avoided crop is damaged over against crop; When multiple tooth tine leaves crop, rapid Rotate 180 degree, and keep this position, up near next crop, Rotate 180 degree rapidly again, the position to tine dish 3 gap over against crop.In this process, tine tooth 4 is with the fragmentation of earth piece, and rake is except weeds between strain.From the movement locus D of the movement locus C of tine tooth A and tine tooth B as can be seen, in the tine motion process, tine tooth 4 movement locus are interlaced, the soil that hardens that has weeds can be separated into particle in small, broken bits, and eliminate weeds, reach the purpose of hoeing up weeds, loosening the soil.
