Description

Hand-held type picking trimming device
Technical Field
The utility model relates to a gardens, bamboo logging technical field, in particular to a device that is used for bamboo picking and gardens pruning.
Background
In the afforestation, need prune the plastic to flowers and plants, generally adopt modes such as chain saw and manual scissors to go on at present, because the chain saw is big from taking engine noise, influence the resident family around especially when the district operation, it is time-consuming and laboursome to adopt manual scissors to prune. In addition, bamboo branches and leaves need to be removed in the bamboo felling process, the branches and leaves are removed by swinging the arms by manually holding a firewood knife in the traditional branch removing process, time and labor are wasted, the working efficiency is low, and especially, the labor cost is high when a bamboo forest needs to be felled.
Disclosure of Invention
The utility model aims to solve the technical problem that a hand-held type picking trimming device is provided to noise problem and bamboo when solving the gardens pruning pick up the problem that the in-process picking is wasted time, hard inefficiency.
The utility model provides a technical scheme that technical problem adopted does: a handheld pruning and trimming device comprises a direct current motor driven by a lithium battery, a motor mounting plate, a handle supporting framework, a bearing seat, a locking pressing plate, a cutter head pressing plate, a transmission mandrel and a protective cover. The direct current motor is arranged on the motor mounting plate, and the motor mounting plate, the handle support framework and the bearing seat are connected through a screw IV; the bearing seat internally mounted has the bearing, and the transmission dabber is installed to the bearing hole, transmission dabber upper end links to each other with DC motor through the key, and the blade disc is installed to the lower extreme of transmission dabber, and the transmission dabber carries out axial positioning by locking clamp plate. The cutter head is connected with the transmission mandrel through a second screw and a cutter head pressing plate; a protective cover is arranged on the bearing seat; the handle supporting framework is provided with a handle shell.
Furthermore, eight cutter teeth in special shapes are arranged on the circumference of the cutter head, the turning radius of a cutter point of each cutter tooth is larger than the turning radius of the root of the cutter tooth, the cutter point and the root of the cutter tooth are in transition through an arc curve, a cutting edge is formed at the back of the cutter tooth along the arc curve, and the included angle of the cutting edge is beta =5 degrees ~ 20 degrees.
The use method of the handheld pruning and trimming device comprises the following steps: the cutter disc is driven by the motor to rotate clockwise at high speed, and the bamboo branches or garden branches are cut and trimmed by the arc cutting edges at the back of each cutter tooth.
Compared with the prior art, the beneficial effects of the utility model are that: the handheld pruning device is light and handy in structure, convenient to carry, suitable for field work as power supply by utilizing the lithium cell, and is more efficient than traditional firewood sword, circular saw and pruning scissors, easy operation, laborsaving. The noise is less than that of a chain saw when the garden is trimmed and modeled.

Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, the handheld pruning device comprises a direct current motor (13) driven by a lithium battery, a motor mounting plate (11), a handle supporting framework (1), a bearing seat (9), a locking pressing plate (8), a cutter head (7), a cutter head pressing plate (6), a transmission mandrel (12) and a protective cover (3). The direct current motor (13) is installed on the motor installation plate (11) through a third screw (14), and the motor installation plate (11), the handle support framework (1) and the bearing seat (9) are connected through a fourth screw (16); bearing frame (9) internally mounted has bearing (10), and transmission dabber (12) are installed to bearing (10) hole, the upper end of transmission dabber (12) links to each other with direct current motor (13) through key (15), and blade disc (7) are installed to the lower extreme of transmission dabber (12), axial positioning is carried out by locking clamp plate (6) in transmission dabber (12). The cutter head (7) is connected with the transmission mandrel (12) through a second screw (5) and a cutter head pressure plate (6); the end face of the bearing seat (9) is provided with a protective cover (3) through a first screw (4); the handle supporting framework (1) is provided with a handle shell (2).
Referring to fig. 2, eight cutter teeth with special shapes are arranged on the circumference of the cutter head (7), the turning radius of the cutter point (a) of each cutter tooth is larger than that of the cutter tooth root (a '), the cutter point (a) of each cutter tooth and the cutter tooth root (a') are in transition by an arc curve, a cutting edge is formed on the back of each cutter tooth along the arc curve, and the cutting edge is shaped as shown in fig. 3, and the included angle of the cutting edge is beta =5 degrees ~ 20 degrees.
The use method of the handheld pruning and trimming device comprises the following steps: the cutter disc is driven by the motor to rotate clockwise at a high speed, bamboo branches or garden branches are cut and trimmed by the arc cutting edges at the back of each cutter tooth, and the turning radius of the root of each cutter tooth is smaller than that of the cutter point, so that a certain included angle exists between the cutting direction of each cutting edge and the feeding direction of each cutting edge when the cutter disc rotates to trim the branches, the cutting edges are in a sliding cutting state, labor is saved under the state, and the cutting edges are sharper when the cutting edges cut the branches.
The above description is only exemplary of the present invention and should not be taken as limiting, and any modifications, equivalents, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
