Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example:
[0028] like Figures 1 to 6 As shown, a garden dead branch pruning device includes a base 3 and a telescopic rod 4, the bottom of the base 3 is fixedly connected to the telescopic rod 4, a saw blade bracket 18 is fixedly arranged on the upper side of the base 3, a rotating spindle 16 is installed inside the saw blade bracket 18, and the front and rear ends of the rotating spindle 16 are rotatably connected to the saw blade bracket 18 through an axle seat 23, a roller saw blade 2 is installed on the rotating spindle 16, a transmission box 5 is fixedly arranged on the front side of the saw blade bracket 18, a driven bevel gear 15 is arranged inside the transmission box 5 and is installed on the rotating spindle 16, a driving motor 6 is installed on the lower side of the transmission box 5, an active bevel gear 17 is installed on the output end of the driving motor 6, and the active bevel gear 17 is meshed with the driven bevel gear 15 for transmission. The roller saw 2 is connected with an arc-shaped limit hook plate 1 at intervals on the upper side, and the width of the limit hook plate 1 is the same as that of the roller saw 2. A first ear plate 7 is fixedly provided on the lower side of the left end surface of the limit hook plate 1, and a second ear plate 8 is fixedly provided on the left end of the base 3. An electric push rod 9 is assembled on the bottom of the second ear plate 8, and the output end of the electric push rod 9 passes through the second ear plate 8 and is fixedly connected with the first ear plate 7. This design solves the problem that the existing electric pruning tools usually do not have a limiting structure, and the pruning direction needs to be manually controlled during the pruning process, the operation is not convenient enough, and the pruning part of the electric pruning tool needs to be kept in contact with the dead branches at all times, resulting in a long manual lifting time, high manual labor intensity, and low pruning efficiency.
[0029] The device can crush and cut off dead branches through the roller saw 2, thereby realizing rapid pruning of dead branches. At the same time, the limit hook plate 1 can hook the dead branches during pruning, thereby realizing the limitation and positioning of the device and preventing shaking and deviation during pruning. In addition, the extension and retraction of the electric push rod 9 can drive the roller saw 2 to move in the direction of the limit hook plate 1, thereby realizing automatic feeding of the pruning stroke, thereby improving the convenience and efficiency of pruning.
[0030] A fixing plate 12 is provided on the lower side of the inner surface of the limit hook plate 1, and two sets of guide rods 13 are fixed on the lower side of the fixing plate 12. The lower ends of the two sets of guide rods 13 penetrate the base 3 and are slidably connected thereto. The setting of the guide rods 13 provides further guide support for the movement of the limit hook plate 1, making the limit hook plate 1 more stable when moving or adjusting, reducing the possibility of shaking or offset, and further enhancing the stability and controllability of the limit hook plate 1.
[0031] Side plates 10 are fixed on both the front and rear sides of the arc-shaped area on the limit hook plate 1, and the height of the side plates 10 is lower than that of the limit hook plate 1. The inner wall of the side plates 10 is provided with multiple groups of cone-shaped spikes 11. The side plates 10 can fit against the dead branches during pruning to achieve the positioning of the device. At the same time, a gap is created between the inner wall of the limit hook plate 1 and the dead branches to prevent the contact with the limit hook plate 1 when the roller saw 2 cuts the dead branches short, thereby protecting the limit hook plate 1 and the roller saw 2. The cone-shaped spikes 11 on the inner wall of the side plate 10 can penetrate into the dead branches, increase the contact area and friction with the dead branches, further improve the stability of the device, and improve the stability and efficiency of pruning.
[0032] The lowest ring surface of the telescopic rod 4 is covered with a rubber anti-skid grip 42, which has good anti-skid performance and can ensure that the operator can hold the telescopic rod 4 stably even in a wet or greasy environment. The anti-skid grip 42 can increase the friction between the palm and the telescopic rod 4 and reduce operational errors caused by hand slippage. A handle 41 is fixed on the telescopic rod 4 on the upper side of the anti-skid grip 42, and the handle 41 provides an additional force point for the operator, so that the operator can control the trimming device more conveniently and ensure the stability of the device.
[0033] A protective baffle 31 is fixedly provided on the right side of the upper end surface of the base 3. The protective baffle 31 can block from the right opening to prevent other objects from contacting the roller saw 2, and can also block debris generated during pruning to protect the operator from injury.
[0034] The base 3 is provided with protective cover plates 14 on both the front and rear sides. The protective cover plates 14 can shield the roller saw 2 from the front and rear sides, and can close the roller saw 2 when the device is not in use to prevent accidental contact and injury, thereby improving the safety of the device.
[0035] Two groups of T-shaped clips 19 are fixed on the inner side surface of the protective cover plate 14, and a T-shaped slide groove 20 adapted to the T-shaped clip strip 19 is opened inside the edge of the base 3, and the T-shaped clip strip 19 is inserted into the T-shaped slide groove 20. The design of the T-shaped clip strip 19 and the T-shaped slide groove 20 enables the protective cover plate 14 to be firmly connected to the base 3, and is not easy to loosen or fall off, and is convenient for adjustment and movement. A card block 21 is fixed at the bottom of the protective cover plate 14, and a card groove 22 adapted to the card block 21 is opened inside the base 3, and the card block 21 can be inserted into the card groove 22. The card block 21 is arranged to cooperate with the card groove 22 to facilitate fixing the protective cover plate 14. The card block 21 cooperates with the card groove 22 to fix the protective cover plate 14. The protective cover plate 14 can be fixed to the front and rear sides of the base 3 by cooperating with the card groove 22 to prevent it from slipping off by itself, thereby realizing shielding and protection of the roller saw 2.
[0036] The upper surface of the protective cover plate 14 is an arc-shaped structure, and the width of the protective cover plate 14 is greater than the diameter of the roller saw 2. This design can achieve comprehensive protection for the roller saw 2 and further enhance the protection effect. A U-shaped notch 24 is provided inside the protective cover plate 14, and the notch 24 is adapted to the shaft seat 23. The U-shaped notch 24 can enable the protective cover plate 14 to fit tightly around the shaft seat 23, thereby enhancing the stability of the protective cover plate 14.
[0037] The working principle of the garden dead branch pruning device is as follows: when it is necessary to prune dead branches, first adjust the telescopic rod 4 to an appropriate length, then insert the device into the dead branches from the opening on the right side, so that the limit hook plate 1 hooks the dead branches, realizes the limit and positioning of the device, and prevents shaking and deviation during pruning. Then start the drive motor 6, and the output end of the drive motor 6 is equipped with an active bevel gear 17, which is meshed with the driven bevel gear 15 inside the transmission box 5. The driven bevel gear 15 is assembled on the rotating main shaft 16, so when the active bevel gear 17 rotates, it drives the driven bevel gear 15 and the rotating main shaft 16 to rotate together. The rotating main shaft 16 is equipped with a roller saw 2, so when the rotating main shaft 16 rotates, the roller saw 2 will also start to rotate. The rotation of the roller saw 2 can crush and cut the dead branches, thereby realizing the rapid pruning of the dead branches. At the same time, start the electric push rod 9 to control the electric push rod 9 to shorten. During this process, the electric push rod 9 drives the roller saw 2 to move toward the dead branches, so that the roller saw 2 continues to crush the dead branches until they are cut off, thereby realizing automatic feeding of the roller saw 2, improving the convenience and efficiency of pruning. After pruning is completed, the electric push rod 9 is controlled to extend, driving the limit hook plate 1 to return to its original position, and then repeating the above steps to prune other dead branches.
[0038] When the device is not in use, the protective cover plates 14 on the front and rear sides of the base 3 are pushed upward until the block 21 is inserted into the slot 22 inside the base 3, so that the protective cover plates 14 are fixed to the outside of the roller saw 2. The protective cover plates 14 can shield the roller saw 2 from the front and rear sides to prevent accidental touch and cause injury.
[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
