Description

Technical Field

[0001] The utility model relates to pruning equipment in forestry technology, in particular to an adjustable pruning device. Background Art

[0002] In the prior art, during the growth of trees, it is necessary to perform intervention pruning on the branches of the trees so as to control the growth direction and growth progress of the branches of the trees; therefore, there are many different kinds of pruning tools for trees in the prior art.

[0003] For example, the “pruner” disclosed in the technical solution with the publication (announcement) number CN201378965Y adopts a scissor-like structure to achieve branch pruning, which is mainly achieved through technical components such as a telescopic rod, scissors, a fixed pulley and a pull rope.

[0004] For example: The technical solution with the publication (announcement) number: CN201299020Y discloses "a high-altitude pruning device", which mainly realizes the pruning function through a pruning saw gear. The structure of the saw gear is obviously more reliable than the pruning structure of scissors, and the pruning quality is higher, it is more labor-saving to use, and the pruning efficiency is correspondingly improved.

[0005] However, in the above technical solutions, whether it is a scissor-type pruning structure or a sawtooth pruning structure, there are certain technical difficulties in use, especially when pruning at high altitudes, the branches cannot be effectively fixed, which makes pruning more difficult, increases the difficulty of pruning, and affects the pruning efficiency and pruning quality.

[0006] Therefore, in order to solve the above problems, it is necessary to develop an adjustable pruning device with a reasonable structure that can improve work efficiency and work quality. Utility Model Content

[0007] The purpose of the utility model is to provide an adjustable pruning device to address the deficiencies of the prior art; the technical solution is as follows:

[0008] An adjustable pruner comprises an adjustable handle; a mounting seat is arranged at the upper end of the adjustable handle; the mounting seat is arranged as a concave structure as a whole, wherein the concave area is arranged as a pruning groove, and a double-headed motor is also installed in the mounting seat, the double-headed motor is located directly below the pruning groove, screw rods are arranged on both sides of the double-headed motor, and screw rod seats are correspondingly installed on the screw rods on both sides, and transverse limit grooves are also arranged on both sides of the mounting seat; and the screw rod seats are arranged with limit blocks embedded in the limit grooves, and the thread directions of the screw rods on both sides are arranged accordingly, and when the double-headed motor drives the screw rods on both sides to rotate, the screw rod seats on the screw rods on both sides can move inward and outward at the same time.

[0009] An L-shaped connecting rod is correspondingly installed at the upper end of the screw rod seat, and a pruning blade is also installed at the end of the connecting rod. The pruning blades on both sides are located on both sides of the pruning groove. The pruning blades on both sides are extended into the pruning groove from both sides under the drive of the screw rod seat to prune the branches stuck in the pruning groove; and the pruning blades on both sides can be retreated to both sides of the pruning groove accordingly.

[0010] Furthermore, the adjustable handle is at least configured as a two-section telescopic handle structure with adjustable length.

[0011] Furthermore, a power supply device for supplying power to the double-headed motor is installed at the end of the adjustable handle; and a button for adjusting the forward and reverse rotation of the double-headed motor is also provided on the adjustable handle.

[0012] Furthermore, the screw rods on both sides of the double-headed motor are correspondingly arranged on the side walls of the mounting seat through bearing components.

[0013] Furthermore, the end positions on both sides of the middle pruning groove of the mounting seat are arranged as slope structures, thereby forming a V-shaped groove structure.

[0014] Furthermore, locking plates are correspondingly installed on both sides of the pruning groove through hinge assemblies; the hinge assemblies are configured as position-limiting hinge assemblies, and the locking plates on both sides can be flipped toward the inside of the pruning groove but cannot be flipped toward the outside.

[0015] Furthermore, the locking plate is configured as an elastic plate structure, and the material of the locking plate is configured as a plastic material.

[0016] Beneficial effects: The utility model has the following beneficial effects:

[0017] 1) The adjustable handle in the device can adjust the length accordingly to adapt to the pruning of branches of different heights; and the front mounting seat is set as a concave structure, so that the branches can be correspondingly clamped in the pruning groove, and the overall structure is set more reasonably;

[0018] 2) In the present device, the pruning is performed by the pruning blades on both sides entering the pruning groove at the same time. This technical solution is more stable and reliable than the previous method of using scissors or saw wheels. The branches can be cut more smoothly and reasonably from both sides, and the structure is stable and reliable;

[0019] 3) The trimming blades on both sides of the device are realized by the structural combination of a double-headed motor, a screw rod, a screw rod seat and a connecting rod. The double-headed motor can drive the trimming blades on both sides to move simultaneously, and the structural design is ingenious and reasonable;

[0020] 4) In this device, the front end of the pruning groove is set as a slope structure, so that the branches can slide smoothly into the pruning groove; in addition, a locking plate is provided, which is installed correspondingly through a hinge assembly and has a certain limiting effect. The locking plate can only be flipped inwards but not outwards, so the branches can enter the pruning groove but cannot go out of the pruning groove. Therefore, the branches can be effectively stuck in the pruning groove and fixed, and pruning will be very smooth and convenient;

[0021] 5). In this device, if a branch is accidentally stuck in the pruning groove, when the branch needs to be removed, since the locking plate is an elastic plate made of plastic, it can also be forcibly removed from the pruning groove, which is more reasonable in structure.

[0025] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an adjustable pruner comprises an adjustable handle 1; a mounting base 2 is arranged at the upper end of the adjustable handle 1; the mounting base 2 is arranged as a concave structure as a whole, wherein the concave area is arranged as a pruning groove 3, and a double-headed motor 4 is also installed in the mounting base 2, the double-headed motor 4 is located directly below the pruning groove 3, screw rods 5 are arranged correspondingly on both sides of the double-headed motor 4, and screw rod seats 6 are correspondingly installed on the screw rods 5 on both sides, and transverse limit grooves 7 are also arranged on both sides of the mounting base 2; and limit blocks 8 embedded in the limit grooves 7 are arranged on the screw rod seats 6, and the thread directions of the screw rods 5 on both sides are arranged accordingly, when the double-headed motor 4 drives the screw rods 5 on both sides to rotate, the screw rod seats 6 on the screw rods 5 on both sides can move inward and outward at the same time.

[0027] An L-shaped connecting rod 9 is also installed at the upper end of the screw seat 6, and a pruning blade 10 is also installed at the end of the connecting rod 9. The pruning blades 10 on both sides are located on both sides of the pruning groove 3. The pruning blades 10 on both sides are extended into the pruning groove 3 from both sides under the drive of the screw seat 6 to prune the branches stuck in the pruning groove 3; and the pruning blades 10 on both sides can be retreated to both sides of the pruning groove 3 accordingly.

[0028] The adjustable handle 1 is at least configured as a two-section telescopic handle structure with adjustable length.

[0029] A power supply device 11 for supplying power to the double-headed motor 4 is also installed at the end of the adjustable handle 1 ; and a button 12 for adjusting the forward and reverse rotation of the double-headed motor 4 is also provided on the adjustable handle 1 .

[0030] The lead screws 5 on both sides of the double-headed motor 4 are correspondingly arranged on the side walls of the mounting seat 2 through bearing members 13 .

[0031] The two side end positions of the pruning groove 3 in the middle of the mounting seat 2 are provided with a slope structure 14, so as to form a V-shaped groove structure.

[0032] Locking plates 16 are also installed on both sides of the pruning groove 3 through hinge components 15; the hinge components 15 are configured as limited hinge components 15, and the locking plates 16 on both sides can be flipped toward the inside of the pruning groove 3, but cannot be flipped toward the outside; the locking plates 16 are configured as an elastic plate structure, and the material of the locking plates 16 is configured as plastic material.

[0033] The specific usage method and working principle of this device are as follows: first of all, the adjustable handle in this device can be adjusted in length, so it can adapt to the pruning of branches at different heights; the front end of the adjustable handle in this device is provided with a mounting seat, a double-headed motor is provided in the mounting seat, screw rods are provided on both sides, and screw rod seats are provided on the screw rods. The screw rod seats are restricted by the limit grooves and the limit blocks, and can drive the connecting rod and the pruning blade accordingly for pruning.

[0034] The device can first adjust the height of the adjustable handle according to the height of the branch to be modified. When in use, the double-headed motor controls the lead screw and the lead screw seat so that the pruning blades are located at both sides and do not extend into the pruning groove; then the adjustable handle is controlled upward to put the branches to be pruned into the pruning groove. Since the pruning groove is concave, the branches can be directly inserted into the groove. Then the double-headed motor is turned on by the button on the adjustable handle. The double-headed motor drives the lead screws on both sides to rotate. It is necessary to set the thread direction on the double-headed lead screw so that the lead screw seat can move inward or outward at the same time.

[0035] After the screw rod rotates, the screw rod seats on both sides can move inward. Since the screw rod seats are located under the limit grooves and limit blocks below, the screw rod seats can move left and right accordingly, thereby driving the connecting rod and the pruning knife on the connecting rod to move inward, thereby cutting off the branches in the pruning groove and completing the pruning.

[0036] The structural setting of the pruning blades on both sides is also very important. They can be set to an overlapping structure, but the position needs to be relatively stable. After the two pruning blades overlap, pruning can be performed to prune the incoming branches.

[0037] In order to allow the branches to enter the pruning groove more smoothly, a slope structure is set at the front end of the pruning groove, so that the branches can slide smoothly into the pruning groove; in addition, a locking plate is provided, which is installed correspondingly through a hinge assembly and has a certain limiting effect. The locking plate can only be flipped inward but not outward, so the branches can enter the pruning groove but cannot go out of the pruning groove. Therefore, the branches can be effectively stuck in the pruning groove and fixed, and pruning will be very smooth and convenient.

[0038] In addition, if a branch is accidentally stuck in the pruning groove and needs to be removed, since the locking plate is an elastic plate made of plastic, it can be forcibly removed from the pruning groove, which is more reasonable in structure.

[0039] The above-mentioned specific implementation mode is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
