Description

A kind of tea place trimmer
Technical field
The utility model relates to a kind of shrub and prunes machinery, and especially a kind of tea place trimmer belongs to the agriculture and forestry machinery technical field.
Background technology
The tea place trimmer is used to prune the edge of the low brushwood of tea tree and so on.Retrieval is found; Application number is that the one Chinese patent application of CN200820101246.8 discloses a kind of backpack tea bush trimmer machine; Relate to a kind of backpack tea bush trimmer machine, this machine comprises power assembly of being made up of miniature gasoline engine and the blade assembly of being made up of upper and lower blade, and power assembly is packed in to be born on the support assembly; The rotation output of power assembly passes to the blade assembly through flexible axle, drives upper and lower blade dislocation motion.Though this machine has small and exquisite nimble advantage, topiary both sides simultaneously, and the fluffy shape of tea is inconsistent, and labour intensity is big, and operating efficiency is low.
Above-mentioned existing trimmer can't be pruned the shrub both sides simultaneously, therefore is difficult to satisfy the deburring requirement on tea tree ridge.
The utility model content
The primary and foremost purpose of the utility model is: propose a kind ofly can prune and can regulate simultaneously the tea place trimmer of trim width and both sides cut-back angles simultaneously to the shrub both sides.
The further purpose of the utility model is: propose a kind of tea place trimmer that can guarantee that both sides cut-back angles symmetry is regulated.
In order to reach above purpose; The tea place trimmer of the utility model comprises power assembly and cutting blade assembly; Have two eccentric wheels that angular position staggers in the housing of said cutting blade assembly; Said two eccentric wheels are in transmission connection through connecting rod and two staggered shaving shape blades respectively, said blade with constitute moving sets from the extended tool magazine of housing; Its improvements are that said blade assembly has left and right two covers, and its upper end is hinged with a left and right end of repairing wide adjusting rod respectively, and the middle part is hinged with an end of a left side, tilt adjustment bar respectively; The chute lockable that the said left and right shell of repairing wide adjusting rod and said power assembly passes through on the shaft is hinged, and said left and right tilt adjustment bar variable bit locking each other connects; Said power assembly has the power input shaft that is supported on the shell; Said power input shaft is in transmission connection with left and right power output spline respectively through left and right bevel gear pair, and said left and right power output spline is inserted into respectively in the corresponding splined hole of the eccentric wheel centre of gyration of left and right cutting blade assembly.
During work, the power of power assembly output can drive left and right cutting blade assembly respectively through left and right power output spline, makes two blades of each cutting blade assembly produce reciprocal shearing motion.Through regulating left and right articulated position of repairing wide adjusting rod and power assembly shell, can regulate the distance between two cutting blade assemblies as required, thereby change trim width; And, can change the pruning inclination angle of both sides as required through regulating left and right tilt adjustment bar latched position each other.Because the left and right splined shaft of the left and right bevel gear pair drive of power assembly can change the inclination angle with above-mentioned adjusting, therefore can and not prune tilt adjustment because of trim width influences power output transmission.
The utility model further improves; In order to make two angles of heel to regulate simultaneously; Thereby not only make things convenient for the adjusting at inclination angle; And guarantee all the time the symmetry of left and right cutting knife, said left and right tilt adjustment bar have respectively extend along its length the relative tooth bar of teeth directional, the adjusting gear with left and right tilt adjustment bar tooth bar engagement is housed in the extended support of said power assembly simultaneously.When the turn adjusting gear, left and right tilt adjustment bar will be under the effect of rack-and-pinion, draws close simultaneously or separates, thereby change the inclination angle simultaneously, keeps symmetry.

Embodiment
Embodiment one
The tea place trimmer of present embodiment is as depicted in figs. 1 and 2, has power assembly 6 and cutting blade assembly 3,8.The structure of cutting blade assembly is referring to Fig. 5, Fig. 6; Has the eccentric wheel that two capacity eccentric bearing 3-10 that angular position staggers constitute in the housing of its left and right shell 3-2, the involutory formation of 3-4; Two eccentric wheels are in transmission connection through connecting rod 3-9 and the two left and right blade 3-7 of staggered shaving shape, 3-6 respectively; Two blades with constitute moving sets from the extended tool magazine of housing, therefore constituted the slider-crank mechanism that rotation is become linear reciprocating motion in fact.Left and right two cover blade assemblies 3,8 upper ends respectively with left and rightly repair wide adjusting rod 5, an end of 5 ' is hinged through bolt 4, the middle part is hinged with an end of left and right tilt adjustment bar 1,7 respectively through bolt 2.Left and right repair wide adjusting rod 5,5 ' and the shell of power assembly 6 hinged through the chute lockable on the shaft.Left and right tilt adjustment bar 1,7 variable bit locking each other connects.Its concrete structure is referring to Fig. 3, has the relative tooth bar of teeth directional that extends along its length on the shaft of left and right tilt adjustment bar 1,7 respectively, and the adjusting gear 11 with left and right tilt adjustment bar tooth bar engagement is housed in the power assembly 6 extended supports simultaneously.This adjusting gear is through locking nut 10 and 9 coaxial connections of crank, and therefore when the rocking-turn crank, adjusting gear can drive left and right tilt adjustment bar simultaneously, the inclination angle of the left and right cutting blade assembly of symmetry change (referring to Fig. 7).
The concrete structure of power assembly 6 is as shown in Figure 4; Has the power input splined shaft 6-4 that is supported on the shell 6-2; One end of this power input splined shaft is connected with the output shaft of hydraulic motor 6-1 through shaft coupling 6-3; The other end is in transmission connection with left and right power output spline 6-5 ' and 6-5 respectively through left and right bevel gear pair 6-9,6-8 ' and 6-9,6-8; The input gear of left and right bevel gear pair is same bevel gear 6-9; The left and right output gear 6-8 ' of left and right bevel gear pair, 6-8 are supported on respectively and are positioned at shell 6-2 and can import on the retainer plate 6-7 that splined shaft 6-4 rotates around power; The overhanging end of left and right power output spline 6-5 ' and 6-5 passes the dust cover 6-6 that can rotate simultaneously with retainer plate 6-7 respectively, is inserted in the corresponding splined hole of the eccentric wheel centre of gyration of left and right cutting blade assembly, realizes the transmission of power and motion.
The tea place trimmer of present embodiment is combined power assembly and two cover cutting blade assemblies; The transmission mechanism of power assembly rationally is set; Make cutting knife tilt adjustment and power export mutually noninterfere, thereby properly settled a difficult problem of simultaneously the shrub both sides being pruned and can regulate simultaneously trim width and both sides cut-back angles.
Facts have proved that its novel structure, light and handy, the flexible operation of reasonable in design, blade assembly are fit to pruning, or the training operation of green Li of large tracts of land tea tree very much.By the installing rack among Fig. 2 12, can it be installed on the walking machine.The blade assembly can the attended operation bar, makes wider that blade prunes by the length of action bars, also can prune branches of tall trees such as tree crowns, makes this trimmer scope of application more extensive.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
