The present invention provides a working device, comprising a working portion and a grip portion. The working portion comprises a driving component and a working component driven by the driving component. The driving component comprises an electric motor and an electric motor housing. The electric motor housing comprises a housing body and a connecting portion located on a rear side of the housing body. At least one air intake hole is formed in the connecting portion, and is in communication with an inner cavity of the housing body. In the working device of the present invention, the driving component is provided with an air intake hole to allow air for cooling an electric motor to enter the interior of the driving component. Further, the working portion can be rotated with respect to the grip portion so as to have an increased working angle, and it can also be ensured that at least one air intake hole is always in communication with the outside when the working portion is in any angular position, so that the use efficiency of the electric motor can be ensured under any use condition.

This disclosure includes a method for pruning a fruit plant. An exemplary method step includes obtaining an image of the fruit plant that has branches. Next, creating exclusion zones surrounding the branches. Then pruning the fruit plant based upon the exclusion zones.

An extendible working machine has a rotation/drive section, a working section, and a rod section which connects the rotation/drive section and the working section, transmits rotational force to the working section, and can be extended and retracted. The rod section has a tube body which can be extended and retracted, and also has a shaft body which extends in the axial direction within the tube body and which can be extended and retracted together with the tube body. The shaft body has a pipe shaft which is supported within the inner tube in a rotatable manner. Helical grooves are formed in the surface of the drive shaft. The drive shaft is connected to the pipe shaft so the pipe shaft can move in the axial direction along the outer surface of the drive shaft and so the rotation of the drive shaft is transmitted to the pipe shaft.

The present invention relates to an intelligent interactive apparatus, system and method that aligns with property trimming and cutting tools such as pole saws, lawnmowers or unmanned aerial drones. More particularly, the present invention relates to a pole saw or autonomous lawnmower with attached functional accessories such as autonomously operated line trimmer or lawn edging devices operating on a 360 degree axis obtaining power and motion on a electro magnetic levitation system and having an attached imaging apparatus assembly that is linked to a display output device allowing for more intelligent and consistent tree, grass, and hedge views and overall control. The tree trimming imaging apparatus assembly of the present invention allows for an intelligent interactive system wherein the method used makes a user capable of a more accurate and safe tree, hedge, or property trimming experience. The present invention's system is linked by superimposed design overlays giving augmented reality guidance, and an interactive imaging apparatus for an improved viewing method. The imaging device enables a more accurate tree, hedge or property grass trimming experience using an imaging and proximity sensors, and laser guided focal area that intelligently follows a grid mapping axis process using artificial intelligence algorithm and defect predictive analytics engine to reduce property maintenance trimming errors, safety risks, and difficulty.

A fluid delivery assembly is operably coupled with a reciprocating saw having a saw blade to deliver a treatment fluid to a cut portion of vegetation as the vegetation is cut. A syringe contains the treatment fluid and a fluid delivery tube has a reservoir end in fluid communication with the syringe and a delivery end adjacent the cut portion of the vegetation. A carrier is contains a portion of the fluid delivery assembly and a harness attached to the carrier has at least one strap for an operator to carry the carrier during operation of the reciprocating saw. A stepper motor is operably coupled to a PCB for storing operating parameters and for executing the operating parameters to induce advancing movement of a plunger relative to the syringe. The operating parameters are provided to the PCB by an external computing device and the PCB and stepper motor receive electrical power through an electrical power and logic cable from a power supply of the reciprocating saw. The fluid delivery tube is provided with a check valve at the reservoir end and the delivery end to retain the treatment fluid within the fluid delivery tube.

A pruner comprising a pruner body, a cutting system, an electric motor adapted to provide driving power for the cutting system, wherein rotation of the electric motor in a first direction is adapted to provide a cutting action, and a control system for controlling the electric motor. The pruner further comprising a blade stuck detection system adapted to detect a blade stuck situation in which the cutting system is not able to reach the closed position, and the control system, as a response to detection of the blade stuck situation, is adapted in a recut operation to rotate the electric motor in a second direction opposite the first direction, and then to rotate the electric motor in the first direction to actuate the cutting system towards the closed position.

A hand-guided garden, forestry and/or construction working apparatus has an inactive state, an active state and a variable setting, as well as an apparatus operator control element which can be activated by a user. In the inactive state, the garden, forestry and/or construction working apparatus is designed to be transferred into the active state triggered by activation of the apparatus operator control element, and in the active state the garden, forestry and/or construction working apparatus is designed to change the setting and not to be transferred into the inactive state triggered by activation of the apparatus operator control element.

A robotic pruning apparatus that can be adapted to fit around a variety of trees and can move along the length of the tree while performing a variety of pruning operations. The pruning apparatus can be configured with a variety of different cutting heads that have multiple degrees of freedom of movement such that they can be used to perform any number of cutting operations along the length of the tree. The apparatus can be remotely operated by a human or can be autonomous or semi-autonomous.

A cutter apparatus comprising a frame having a mounting member connectable to a piece of prime mover equipment; a cutter assembly connected to the frame, the cutter assembly comprising a support member having a first end; a drive shaft having a first end journaled to the first end of the support member; and a plurality of discrete cutter members stacked on the drive shaft so as to be engaged with an adjacent one of the cutter members, each of the cutter members having at least one cutting edge; and a drive assembly connected to the drive shaft in a way that activation of the drive assembly causes the drive shaft to rotate and thereby rotate the cutter members. The frame may have a base and an extension arm pivotally connected to the base. The support member may be pivotally connected to the extension arm.
