Description

Hand-held shears for green tea tree

The utility model relates to a kind of afforestation machinery and tea bush trimmer machinery, especially portable hedgerow tea bush trimmer machine.

At present, known hedgerow, tea bush trimmer machinery adopt the beta pruning pincers more, the effort and efficient is low.The single trimmer of PST75R of Zhejiang Kawasaki Tea Industry machinery Co., Ltd assembling, the 0.8ps gasoline engine drives, and price is very high, is the operation of single action cutter, and cutting efficiency is lower.

The purpose of this utility model is for overcoming the portable hedgerow tea bush trimmer machine that above-mentioned technical deficiency part provides.

The purpose of this utility model is achieved in that on a portable cutting rack, adopts my patent No. 92236179.7, two moving knife cutters of sheave fork transmission, and with the miniaturization of sheave fork transmission mechanism, tangentially link with double sickle cutterbar; Motor type and gasoline engine model all can carry out hedgerow and tea bush trimmer operation.

Owing to take such scheme, two moving knife can improve cutting efficiency; The micro machine type maintains simple and conveniently, with low cost, is applicable to that power supply is local easily; Gasoline engine model, cost are slightly high, but the operation maneuverability, adaptability is strong.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 3, sheave fork transmission mechanism parameter are selected and small-sized body structure profile

The structure of Fig. 4, double sickle cutterbar and parameter are selected figure

Shown in Figure 1, portable (motor type) hedgerow tea bush trimmer machine is to be made of micro machine (1), portable cutting rack (3), sheave fork transmission mechanism (4), double sickle cutterbar (5); The concentric binding of fluted roller shaft of the power take-off of micro machine (1) and sheave fork transmission mechanism (4), tangentially link by the fork sliding sash of sheave fork transmission mechanism (4) and the axle of double sickle cutterbar (5), and by pole and the sliding bed of cutter (10) binding, the sliding bed of cutter (10) links by flat head screw (12) and portable cutting rack (3), operator is connected (7) one ends with cable, one end and micro machine (1) axis links, a branches and leaves guide plate (11) is arranged, palm top handgrip (6) on the portable cutting rack (3), (7) prune operation; A generator is with in field work, 3～5 electric mowers is formed a unit carry out operation.Figure 2 shows that the gasoline engine model structure, increase a decelerator (8) between the sheave of the power take-off of gasoline engine (2) and sheave fork transmission mechanism (4), operator directly is connected (9) with portable cutting rack (3), portable cutting rack (3) links with the casing of sheave fork transmission mechanism (4), constitutes the support of gasoline engine (2); Other structure is identical with the motor type; Operation is carried out in palm top handgrip (6), (9).

Motor and gasoline engine parameter are selected as follows:

(1) motor: 220v, 660w, 2.8A, 0.8ps, 1600 rev/mins.

(2) gasoline engine: 0.8ps, 5600 rev/mins, operating rate: 4000～5000 rev/mins.

All require stable performance, durable in use, energy consumption is low, and is in light weight.

The parameter that Figure 3 shows that sheave fork transmission mechanism is selected and small-sized body structure, the sheave (13) of sheave fork transmission mechanism (4) has two tracks to do pendulum groove (14), (15) of relative motion, pendulum groove angle (16) is 150 °, sheave circles, fork swing 2 times, cutter travel are walked one back and forth; Fork (19), (20) A, B, C 3 points, AB=BC, the roller of fork, the roll sleeve center is around intersecting on the axis with sheave, the fulcrum roller of fork is fixed on the support (18), fork sliding sash (22) tangentially links with the movable arbor of upper cutter (25), sliding sash (23) tangentially links with the movable arbor of following knife section (26), the sliding bed of cutter (10) links with pole (21), the sliding bed of cutter (10), upper cutter (25), between following knife section (26) and the casing (28) individual packing ring (27) is arranged, whole sheave fork transmission mechanism dwindles at long 135mm, wide 55mm, in the middle of the casing of high 55～25mm (28); Gasoline engine model increases a decelerator (8) between output shaft of gasoline engine (29) and fluted roller shaft (17), speed reducing ratio 1: 3, after slowing down, the Jian Qie Endangered of cutter lead be 1250～1500 back and forth/minute; Cutting branch diameter＜10mm.

The structure and the parameter that Figure 4 shows that double sickle cutterbar are selected, double sickle cutterbar is made of knife section (26) under sliding bed (10) upper cutter (25), on the sliding bed of cutter (10), a chute that falls in (30) is all arranged below, on, the slide rail (31) that following knife section slide plate all has a protrusion to go, (32), on, under intermesh, stablize bolt by the bolt hole (33) on the sliding bed of cutter and last, screw rod sliding sash (34) on the following knife section slide plate will be gone up, following knife section is stabilized on the sliding bed, the parameter of screw rod sliding sash (34) and the stroke of knife section and bolt size match, the sliding bed of cutter (10) wide 25mm, on, the wide 20mm of following knife section slide plate (37), the long 20mm of cutting teeth (38), cutter travel (39) t ₁18mm+t ₂18mm=36mm, knife section cutting edge gradient (36) is 10 °～15 °; Swath 720mm～792mm; 4～5 kilograms on complete machine structure weight micro machine type; 5～6 kilograms of gasoline engine models.
