Detailed Description
In order to better understand the technical content of the invention, specific embodiments are provided below, and the invention is further described with reference to the accompanying drawings.
Referring to fig. 1-2, a vegetation trimming means for afforestation, includes power arm 1, cutting knife 2, wedge 3 and actuating mechanism 4, two power arm 1 is articulated each other, the middle part of cutting knife 2 articulates the head end of power arm 1, 3 sliding connection of wedge are in the head end of power arm 1, wedge 3 along promote during power arm 1 slides cutting knife 2 rotates, the end of power arm 1 is equipped with actuating mechanism 4, actuating mechanism 4 is used for the drive wedge 3 along power arm 1 slides.
When the pruning machine is used, the power arm 1 is held by hands, and a worker rotates the power arm 1 to drive the cutting knife 2 to move, so that the cutting knives 2 move oppositely to prune branches. The middle part of cutting knife 2 is articulated with the head end of power arm 1, consequently, cutting knife 2 except can be along with the motion of power arm 1, can also rotate relative power arm 1. Set up wedge 3 at the head end of power arm 1, can promote cutting knife 2 when wedge 3 moves to make cutting knife 2 rotate relative to power arm 1, change the contact angle of cutting knife 2 and branch. Wedge 3 is connected with actuating mechanism 4, and actuating mechanism 4 sets up at the end of power arm 1, when pruning the branch and meetting the resistance big, adjusts the angle of cutting knife 2 through actuating mechanism 4 for the contact angle of cutting knife 2 and branch changes, makes the contact surface of cutting the branch reduce, and cutting knife 2 is bigger to the pressure of branch under the same pruning dynamics, makes to cut the branch more easily, accomplishes the pruning of vegetation. Cutting knife 2 and power arm 1 articulated position are at the middle part, and the contact site of branch and cutting knife 2 also is at the middle part of cutting knife 2 when pruning the branch, and one side of cutting knife 2 is more close with the branch of being pruned when cutting knife 2 rotates, and the opposite side is farther away from with the branch of being pruned to reduce the contact surface of cutting knife 2 and branch by a wide margin.
Specifically, actuating mechanism 4 includes drive mechanism 5 and slide bar 6, slide bar 6 and power arm 1 sliding connection, slide bar 6 passes through when sliding drive mechanism 5 drives wedge 3 slides. The sliding rod 6 is used as a power input end, and the sliding of the sliding rod 6 is operated to drive the transmission mechanism 5 to move, so that the wedge-shaped block 3 is driven to move. Can promote cutting knife 2 to rotate when wedge 3 removes, and cutting knife 2 can not promote wedge 3 and remove to reach the effect of auto-lock, solve the problem of at will rotating at the in-process cutting knife 2 of pruning. The component force of the wedge-shaped block 3 acts on the cutting knife 2, and the component force is larger than the acting force acting on the wedge-shaped block 3, so that the branch can be trimmed more labor-saving.
Specifically, power arm 1 includes forearm 7, first spring 8, V-arrangement articulated elements 9 and postbrachium 10, two the middle part of forearm 7 of power arm 1 is articulated each other, forearm 7, first spring 8 and postbrachium 10 are series connection in proper order, the end of forearm 7 and the front end of postbrachium 10 are passed through V-arrangement articulated elements 9 and are connected, promote during forearm 7 and postbrachium 10 relative rotation slide bar 6 slides. In the natural state the front arm 7 and the rear arm 10 are in a straight line. The staff holds back arm 10, is close to two back arms 10 each other, and back arm 10 drives forearm 7 motion through first spring 8 and V-arrangement articulated elements 9 to make cutting knife 2 be close to each other, prune the branch. When the resistance that forearm 7 received was too big, the relative forearm 7 pivoted angle of postbrachium 10 reached the default to make forearm 7 and postbrachium 10 contained angle reduce, the front end of postbrachium 10 is close to the rear end of forearm 7, thereby promotes the slider, and then adjusts the angle of cutting knife 2. The angle adjusting device can be operated by one hand, the angle of the cutting knife 2 can be adjusted only by operating the power arm 1, and the operation is convenient.
The invention can automatically adjust the contact surface of the cutting knife 2 and the branch along with the resistance of pruning the branch in the using process, thereby avoiding the problem of misalignment of two pruning positions caused by changing the pruning angle. The sliding rod 6 and the rear arm 10 can be kept at a preset distance, or a spring keeps a preset pre-tightening force, and the contact area between the cutting knife 2 and the branch can be adjusted when the trimming force reaches a preset value. When the tree pruning device is used for pruning branches with small diameters, the tree pruning device can be the same as a common pruning device. When pruning the branch that the diameter is big, if the resistance of pruning reaches the default, the area of contact of cutting knife 2 and branch for cutting knife 2 and vertical area of contact reduce.
Specifically, the V-shaped hinge 9 includes a first connecting rod 11, a second connecting rod 12 and an L-shaped rod 13, the first connecting rod 11 is hinged to the second connecting rod 12, the L-shaped rod 13 is disposed on both the first connecting rod 11 and the second connecting rod 12, and the two L-shaped rods 13 are matched with each other to limit the opening angle of the first connecting rod 11 and the second connecting rod 12. The bending parts of the two L-shaped rods 13 are hooked together, so that the excessive opening angle of the first connecting rod 11 and the second connecting rod 12 is avoided, the first spring 8 is provided with the moving pretightening force, and the front arm 7 and the rear arm 10 rotate relative to each other only when the trimming resistance reaches a preset value.
Specifically, the transmission mechanism 5 is a transmission rod, the transmission rod is connected with the front arm 7 in a sliding manner, and the front arm 7 is provided with a second spring 14 for driving the transmission rod to move towards the sliding rod 6. The sliding rod 6 is in contact with the end of the rear arm 10 under the action of the second spring 14, while the second spring 14 is able to bring the driving rod and the sliding rod 6 back into position.
Specifically, the wedge block 3 is provided with a sliding groove 15, a sliding ball 16 is arranged in the sliding groove 15, and the sliding ball 16 is connected with one end of the cutting knife 2 through a connecting rod. Preferably, the connecting rod is connected to an end of the cutting blade 2 near the rear arm 10. When wedge 3 removes to the direction that is close to cutting knife 2 middle part, promotes cutting knife 2 rotates for the one end that is close to back arm 10 of cutting knife 2 rotates to the direction that is close to the branch, is convenient for prune the branch.
Specifically, the side surface of the middle part of the cutting knife 2 is provided with a mark 17. The branches are convenient to align to the middle part of the cutting knife 2.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
