Fig. 3 shows a side view of the standing work apparatus shown in fig. 1. For the purpose of illustration, the drawings show only the structures pertinent to the present invention.

Referring to fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides a standing type work apparatus. In the present embodiment, a standing work implement is described by taking a standing lawnmower as an example. The standing work apparatus includes a work apparatus main body 10, a step plate 101, and an operation lever 20.

The working instrument body 10 has a first end b1 and a second end b2 opposite to the first end b 1. The pedal 101 is provided at the second end b2 of the work implement body 10, and is used for carrying a person who manipulates the work implement body 10 to perform a lawn mowing operation. One end of the operating lever 20 is rotatably connected to the work implement body 10 about an axis parallel to the pedal 101, and the other end of the operating lever 20 is provided with a manipulation portion 21 for manipulating the work implement body 10. The operating lever 20 includes a first position a1 and a second position a2 during rotation about the axis.

When the operating lever 20 is in the first position a1, the operating lever 20 is disposed at an angle to the pedal 101 toward the first end b1, and a line connecting the geometric centers of the operating unit 21 and the pedal 101 is disposed at an acute angle to a vertical line passing through the geometric center of the pedal 101, so that a person on the pedal 101 can hold the operating unit 21 to control the working device body 10 to perform a lawn trimming operation.

When the operating lever 20 is in the second position a2, the operating lever 20 is disposed obliquely with respect to the pedal 101 toward the second end b2, and the manipulation unit 21 is located outside the work implement body 10, so that a person on the ground behind the work implement body 10 (i.e., outside the second end b2 of the work implement body 10) can manually manipulate the manipulation unit 21 to control the work implement body 10 to perform an edging operation.

In the actual use process of the standing type working device, the operating rod 20 can be rotated to the first position a1, so that a person can stand on the pedal 101 and control the working device body 10 to move by holding the operating part 21 with hands, thereby facilitating the quick lawn trimming operation. When trimming (i.e., trimming) around a lawn or an obstacle is required, the operating lever 20 may be rotated to the second position a2, a person may stand on the ground behind the work implement body 10, and the control unit 21 is held by the hand to control the work implement body 10 to perform the trimming, so that an external force applied by the person may be transmitted to the work implement body 10 through the operating lever 20 to correct the proceeding direction of the work implement body 10 in real time, i.e., the proceeding direction of the work implement body 10 may be more flexibly controlled, so that the standing work implement may proceed closely to the lawn edge or the obstacle, and the trimming with high quality may be accomplished. Therefore, manual trimming operation is avoided, and the lawn trimming efficiency is improved.

It is understood that the manipulation part 21 may include a button, a lever, and the like, and by pressing the button or toggling the lever, the traveling direction and the traveling speed of the working device main body 10, the start and stop of the mowing mechanism for cutting (i.e., a working part described below) of the stand-up working device, and the like are controlled.

In particular, in the embodiment, the distance from the manipulating part 21 to the pedal 101 in the direction perpendicular to the pedal 101 when the operating lever 20 is in the first position a1 is greater than the distance from the manipulating part 21 to the pedal 101 in the direction perpendicular to the pedal 101 when the operating lever 20 is in the second position a 2. In this way, when the operating lever 20 is at the first position a1, the person standing on the pedal 101 holds the manipulation unit 21 with his/her hand and manipulates the work implement main body 10 to perform the dressing work; when the operating lever 20 is at the second position a2, a person standing on the ground behind the work implement main body 10 holds the operating unit 21 with his/her hand and operates the work implement main body 10 to perform an edging operation.

In the embodiment of the present invention, the connection position of the operation lever 20 and the working device main body 10 is located between the pedal 101 and the first end b 1. In this manner, it is convenient for a person standing on the pedal 101 to hold the operation manipulation portion 21 with the hand to manipulate the work implement main body 10.

In particular, in the embodiment, the operating lever 20 is at a first position a1, which is more inclined to the pedal 101 than at a second position a2, which is inclined to the pedal 101. In this way, when the operating lever 20 is at the first position a1, the person standing on the pedal 101 holds the manipulation unit 21 with his/her hand and manipulates the work implement main body 10 to perform the dressing work; when the operating lever 20 is at the second position a2, a person standing on the ground behind the work implement main body 10 holds the operating unit 21 with his/her hand and operates the work implement main body 10 to perform an edging operation.

In a particular embodiment, the axis is perpendicular to the direction of travel of the standing work apparatus. In this manner, the operating lever 20 is made rotatable in a vertical plane parallel to the direction of travel of the standing work apparatus to the first position a1 or the second position a 2. It is to be understood that the traveling direction of the stand-up type working instrument is the direction in which the second end b2 of the working instrument main body 10 points toward the first end b1 (i.e., the left-right direction in fig. 1).

In particular embodiments, the acute angle is greater than 10 ° and less than 20 °. Preferably, the acute angle is 15 °. In this way, it is more convenient for a person standing on the pedal 101 to hold the operation manipulation part 21 when the operation lever 20 is in the first position.

In the embodiment, when the operating lever is in the first position, the manipulation part 21 is spaced from the pedal 101 by 1m to 1.2m in a direction perpendicular to the pedal 101. Thus, the height of the operation part 21 is prevented from being too high when the operation rod 20 is at the first position, and it is more convenient for a person standing on the pedal 101 to hold the operation part 21.

In the embodiment, when the operating lever 20 is in the first position, the manipulation part 21 is 25cm to 35cm away from the geometric center of the pedal 101 in a direction parallel to the pedal 101. Preferably, when the operating lever 20 is in the first position, the manipulation part 21 is spaced from the geometric center of the pedal 101 by a distance of 32cm in a direction parallel to the pedal 101. Thus, it is avoided that the operating lever 20 is farther from the person standing on the pedal 101 when in the first position, and it is more convenient for the person standing on the pedal 101 to hold the operating portion 21.

In particular embodiments, the operating rod 20 is extendable and retractable along its longitudinal direction. Thus, the position of the operation part 21 can be accurately adjusted by adjusting the length of the operation rod 20, and the operation part 21 can be more conveniently held by a person. Further, the operating rod 20 may be an electric telescopic rod, and other structures may also be adopted to achieve the telescopic effect of the operating rod 20, which is not limited herein.

In the embodiment of the present invention, the first end b1 and the second end b2 of the working device main body 10 are provided with the steering wheel 32 and the driving wheel 34 for supporting the working device main body 10, respectively, and the steering wheel 32 includes at least one and the driving wheel 34 includes two. The working device body 10 is further provided with two driving mechanisms (not shown) for driving the two driving wheels 34 to rotate, respectively. Thus, the two driving wheels 34 are driven to rotate by the two independent driving mechanisms, and zero-angle steering of the standing type working machine can be realized, so that the overlapping rate of the traveling paths of the standing type working machine during lawn trimming is reduced, and the lawn trimming efficiency is improved. Alternatively, the two drive wheels 34 are spaced apart in a direction perpendicular to the direction of travel of the stand-up work apparatus.

In the illustrated embodiment, each of the driving mechanisms includes a driving member (not shown) and a speed reducer (not shown), an output shaft of the driving member is connected to an input end of the speed reducer, and an output end of the speed reducer is connected to a corresponding one of the driving wheels 34. In this way, the power of the driving member is transmitted to the driving wheel 34 after being decelerated by the decelerator, and the driving wheel 34 is driven to rotate. Alternatively, the drive member may be a drive motor.

In order to provide the driving member with electric energy, in one embodiment, the stand-up type working machine further includes an energy storage battery (not shown) disposed on the working machine body 10 and electrically connected to the driving member to provide the driving member with electric energy. Alternatively, the energy storage battery may employ a lithium battery. Therefore, the lithium battery is adopted, zero emission and zero pollution of the standing type working instrument are realized, and the energy conservation and the environmental protection are realized.

In an embodiment of the invention, the work apparatus body 10 is further provided with a balancing system (not shown) for controlling the center of gravity of the standing work apparatus to be always between the steering wheel 32 and the driving wheel 34, so as to enhance the stability of the standing work apparatus. Thus, under various working conditions, such as when a person stands on the pedal 101 and when the person does not stand on the pedal 101, the balance system can enable the center of gravity to be located between the steering wheel 32 and the driving wheel 34, and the standing type working machine is guaranteed to have good stability. The balance system can be realized by instruments such as a gyroscope and the like, is a relatively mature technology in the technical field of balance, and is not repeated herein.
