Description

Technical Field

[0001] The invention relates to the technical field of pruning shears, in particular to an electric pruning shears. Background Art

[0002] The current pruning shears blade set generally includes two blades that can move back and forth relative to each other. The two blades can be two moving blades, or one moving blade and one fixed blade. The two blades are usually in the shape of long strips, and a serrated structure is provided on both sides of each blade. The blade set of this pruning shear is relatively large in size and is suitable for working in large areas, but not suitable for working in small areas. For example, it is more laborious to repair shrubs growing against the wall, and the work scenario is not refined; when pruning thicker shrubs or branches, the two reciprocating serrated blades require the operator to apply horizontal force to both sides with a handheld device during work, so that the pruning work can be carried out. However, this method has the defects of being more labor-intensive, easy to slip teeth, and difficult to exert force, which affects the pruning efficiency. When cutting thicker branches, the commonly used serrated blades are not suitable for force cutting, and it is easy to cause the blade to get stuck in the branch. Summary of the invention

[0057] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] like Figure 1-Figure 10 The electric pruning shears shown include a body 1, a blade mechanism 2, a transmission mechanism 3 and an electric drive mechanism 4. The blade mechanism 2 includes two horizontally arranged serrated blades 21 and two knife winches 22 with vertical axes. The two serrated blades 21 can slide back and forth with each other along their length directions. The serrated blades 21 are transmission-connected to the transmission mechanism 3. The two knife winches 22 are symmetrically arranged along the vertical surface of the body 1. The two knife winches 22 are rotatably arranged on the body 1. The transmission mechanism 3 is transmission-connected to the knife winches 22. The electric drive mechanism 4 is transmission-connected to the serrated blades 21. The blades on the outer side walls of the two knife winches 22 are staggered.

[0059] The electric pruning shears designed by the present invention can prune thicker branches, shrubs, etc., and achieve different pruning effects through the serrated blades 21 and the knife capstans 22 installed at different positions. The serrated blades 21 are suitable for quickly pruning smaller shrubs in a large range, while in a narrow area or when encountering thicker branches, the knife capstans 22 installed at the front end of the body 1 are used for pruning. When working, the serrated blade 21 drives the two knife capstans 22 to rotate around their own axes during the reciprocating motion, and the two knife capstans 22 rotate inward synchronously to achieve shredding in the staggered area. Function, compared with the lateral force of the serrated blade 21, when the knife winch 22 is used, the operator can drive the device as a whole to move forward, and push the thicker branches to be pruned to between the two knife winches 22 for shredding, thereby completing the pruning work. The operator can exert force more smoothly, making it difficult for the knife winch 22 to slip, and the shearing effect of the knife winch 22 is stronger than that of the serrated blade 21. When pruning thicker branches, the knife winch 22 is more stable than the serrated blade 21, is not easy to break teeth, and is not easy to get stuck in the middle of the branch and cannot move, thereby improving the scope of use of the equipment.

[0060] When the electric drive mechanism 4 is working, it drives the two serrated blades 21 in the blade mechanism 2 to move horizontally. At this time, the two serrated blades 21 move back and forth relative to each other, and in this process, it drives the transmission mechanism 3 connected thereto to move, and then drives the two knife winches 22 at the top to rotate toward each other through the transmission mechanism 3, thereby realizing the crushing drive function.

[0061] The body 1 includes a main body 11 and a connecting seat 12, the connecting seat 12 is installed at the front end of the main body 11, the connecting seat 12 includes an upper cover 121 and a lower cover 122, the serrated blade 21 is located between the main body 11 and the connecting seat 12, the transmission mechanism 3 includes a first connecting component 31, a first connecting rod 33 and a second connecting component 32, the second connecting component 32 is transmission-connected to an end of the serrated blade 21 away from the main body 11, the second connecting component 32 is transmission-connected to an end of the first connecting rod 33 close to the serrated blade 21, the first connecting component 31 is rotatably arranged on the connecting seat 12, the first connecting component 31 is transmission-connected to an end of the first connecting rod 33 away from the second connecting component 32, the first connecting component 31 is used to drive the knife capstan 22 to rotate around the axis of the knife capstan 22 itself, and the first connecting component 31 is located at the eccentric part of the knife capstan 22.

[0062] The transmission mechanism 3 and the blade mechanism 2 are installed by connecting the upper cover 121 and the lower cover 122 of the seat 12. The transmission mechanism 3 converts the driving force of the serrated blade 21 to reciprocate in the horizontal direction into a rotational driving force that drives the knife winch 22 to rotate around its own axis through the first connecting rod 33. The first connecting component 31 is used to connect one end of the first connecting rod 33 to the knife winch 22, and the second connecting component 32 is used to connect the other end of the second connecting rod 328 to the serrated blade 21.

[0063] like Figure 6-Figure 7 As shown, the first connecting component 31 includes a connecting shaft 311, a first rotating disk 312, a first transmission rod 313 and a first transmission disk 314. The first rotating disk 312 is installed on the upper cover 121 of the connecting seat 12 through the connecting shaft 311. The connecting shaft 311, the first rotating disk 312 and the knife capstan 22 are coaxial. The first rotating disk 312 is located directly above the knife capstan 22. The first transmission rod 313 is vertically rotatably installed between the first rotating disk 312 and the knife capstan 22. The two ends of the first transmission rod 313 are respectively connected to the first rotating disk 312 and the knife capstan 22 for transmission. The first transmission disk 314 is located in the knife capstan 22. The first transmission disk 314 is located at the eccentric position of the knife capstan 22 and can rotate around its own axis in the knife capstan 22. The first transmission rod 313 is connected to the first transmission disk 314. The first transmission rod 313 and the first transmission disk 314 are coaxially arranged, and the end of the first connecting rod 33 is connected to the first transmission rod 313.

[0064] When the first connecting rod 33 moves, it drives the first transmission rod 313 connected thereto to move. Under the limiting action of the first turntable 312 and the first transmission disk 314, the first transmission rod 313 rotates around the axis of the connecting shaft 311 and the knife capstan 22, thereby driving the knife capstan 22 and the first turntable 312 to rotate around their own axes, thereby realizing the function of driving the knife capstan 22 to rotate, and the first turntable 312 rotates following the knife capstan 22.

[0065] like Figure 5-Figure 10 The second connecting assembly 32 shown includes a first sliding block 321, a second sliding block 322 and a second transmission rod 323. The first sliding block 321 and the second sliding block 322 can both slide along the length direction of the serrated blade 21. The lower cover 122 is provided with a first sliding groove 1221 for the first sliding block 321 to slide, and the upper cover 121 is provided with a second sliding groove 1211 for the second sliding block 322 to slide. The second transmission rod 323 is vertically fixedly installed on one side of the serrated blade 21. The two serrated blades 21 are provided with an avoidance groove 211 for avoiding the second transmission rod 323 fixedly connected to the other serrated blade 21. The second transmission rod 323 is transmission-connected to the first connecting rod 33, and the two ends of the second transmission rod 323 are respectively connected to the first sliding block 321 and the second sliding block 322.

[0066] The second connecting component 32 cooperates with the first sliding block 321 and the first sliding groove 1221, so that the second transmission rod 323 connected to the serrated blade 21 can slide back and forth on the lower cover 122. The second sliding groove 1211 and the second sliding block 322 on the upper cover 121 cooperate to enable the second transmission rod 323 to slide back and forth on the upper cover 121, that is, the serrated blade 21 drives the second transmission rod 323 to drive the first connecting rod 33 to move during the movement, thereby realizing the transmission function of the second connecting component 32 to the first connecting rod 33.

[0067] like Figure 6-Figure 10 The second connecting assembly 32 shown also includes a driving gear 324 and a driven gear 325. The driving gear 324 is smaller than the driven gear 325. The driving gear 324 is connected to the second transmission rod 323 in a transmission manner. The driving gear 324 and the driven gear 325 are both installed in the connecting seat 12. The driving gear 324 is meshed with the driven gear 325. The driven gear 325 is connected to the first connecting rod 33 in a transmission manner.

[0068] In order to increase the chopping driving force of the knife capstan 22 when it rotates, the chopping capacity of the knife capstan 22 is improved by reducing the speed and increasing the torque, so that the knife capstan 22 still has a strong shear force when pruning thicker and harder branches. The second transmission rod 323 drives the driving gear 324 to rotate when following the serrated blade 21 to reciprocate. The driving gear 324 drives the driven gear 325 meshing with the driving gear 324 to rotate when rotating. The driven gear 325 drives the first connecting rod 33 to move when rotating, and then drives the first connecting assembly 31 to move through the first connecting rod 33. Since the driving gear 324 is smaller than the driven gear 325, the speed of the knife capstan 22 is reduced and the torque of the knife capstan 22 is increased during the transmission process, thereby improving the chopping capacity of the knife capstan 22 for branches. When pruning thicker branches, the knife capstan 22 is more stable than the serrated blade 21, is not easy to break teeth, and is not easy to get stuck in the middle of the branch and cannot move, thereby improving the scope of use of the equipment.

[0069] The second connecting assembly 32 also includes a third transmission rod 326, a fourth transmission rod 327 and a second connecting rod 328. The third transmission rod 326 is vertically arranged at the eccentric position of the driving gear 324, one end of the second connecting rod 328 is connected to the second transmission rod 323, and the other end of the second connecting rod 328 is connected to the third transmission rod 326. The fourth transmission rod 327 is vertically arranged at the eccentric position of the driven gear 325, and one end of the first connecting rod 33 away from the first connecting assembly 31 is connected to the fourth transmission rod 327.

[0070] The installation of the driving gear 324 is achieved through the third transmission rod 326. During the reciprocating horizontal movement of the second transmission rod 323, the third transmission rod 326 installed at the eccentric position of the driving gear 324 is driven to move through the second connecting rod 328, thereby driving the driving gear 324 to rotate around its own axis. The rotation of the driving gear 324 drives the driven gear 325 meshing therewith to rotate, thereby driving the fourth transmission rod 327 connected to the eccentric position of the driven gear 325 to rotate. When the fourth transmission rod 327 rotates, it drives the first connecting rod 33 connected thereto to move. The first connecting rod 33 drives the knife capstan 22 to rotate, thereby realizing the transmission function of the second connecting component 32.

[0071] The third transmission rod 326 and the driving gear 324 are detachably connected via the first insertion hole 3241 , the fourth transmission rod 327 and the driven gear 325 are detachably connected via the second insertion hole 3251 , and the upper cover 121 and the lower cover 122 are detachably connected.

[0072] The detachable connection between the upper cover 121 and the lower cover 122 can facilitate the replacement of the blade set, that is, the broken or worn serrated blade 21 or the knife winch 22 can be disassembled and replaced. The setting of the first hole 3241 and the second hole 3251 can facilitate the removal of the upper cover 121 from the lower cover 122, thereby facilitating the replacement operation.

[0073] The top end of the connecting shaft 311 is fixedly connected to the upper cover 121 by bolts, the connecting shaft 311 is connected to the first turntable 312 by a bearing, the first sliding block 321 and the second sliding block 322 are rotatably connected to the second transmission rod 323 by bearings, and both ends of the second transmission rod 323 are provided with a connecting head 3231 that can rotate with the second transmission rod 323, and the connecting head 3231 is fixedly connected to the first sliding block 321 or the second sliding block 322 by bolts.

[0074] When the upper cover 121 needs to be removed from the lower cover 122, the bolts can be removed from the connecting shaft 311 to facilitate the connection or disassembly of the connecting shaft 311 and the upper cover 121. The connecting head 3231 on the second transmission rod 323 can achieve a detachable connection with the first sliding block 321 or the second sliding block 322, which facilitates the disassembly or installation of the blade and the transmission mechanism 3 and improves the efficiency of blade replacement and installation.

[0075] like Figure 1-Figure 5 The two serrated blades 21 are installed in reverse order in the lower cover 122 . A transmission groove 212 is provided at one end of the two serrated blades 21 close to the body 11 . The electric drive mechanism 4 is respectively connected to the two serrated blades 21 through the transmission groove 212 .

[0076] During operation, the electric drive mechanism 4 works, and two rotatable rotating disks 41 correspond to the transmission grooves 212 on the two serrated blades 21. During the rotation of the rotating disk 41, the two serrated blades 21 connected thereto are driven to reciprocate horizontally, thereby realizing the electric drive function.

[0077] like Figure 3 The main body 11 is provided with a fixed forward push handle 111 .

[0078] By fixing the forward push handle 111, the operator can apply greater force forward when holding the device, so that thicker branches are clamped between the two knife winches 22. When pruning thicker branches, the knife winches 22 can be more stable and have a stronger cutting force. At the same time, the operator can further increase the contact surface between the staggered position of the knife winches 22 and the branch by pressing forward with the fixed forward push handle 111, thereby improving the shearing stability and the shearing effect.

[0079] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
