The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 is a perspective view showing the branch and leaf cutting device 1 of the present invention. Fig. 2 is a diagram illustrating the respective components of the branch and leaf cutter 1 according to the present invention. The branch and leaf cutting device 1 comprises a mounting seat 10, a cutting mechanism 20, an adjusting mechanism 30 and a collecting mechanism 40. It is understood that the collection mechanism 40 may be omitted, and may be configured according to actual requirements.

As shown in fig. 1, the mounting seat 10 includes a support structure 101, a housing 102 mounted on the support structure 101, and a receiving portion 103 mounted below the housing 102. The support structure 101 supports the housing 102 on the ground.

The supporting structure 101 is shown as a four-leg bracket 1011 in fig. 1, and two brackets 1011 are respectively fixed on two sides of the housing 102 by a locking mechanism such as screws, and a triangular shape is formed between the two brackets 1011 on the same side. Two adjacent brackets 1011 on different sides are connected by a cross bar 1012 with the same length, and each bracket 1011 can be further arranged into a structure capable of being adjusted in a multi-section telescopic manner, so that the height of the mounting seat 10 can be conveniently adjusted while the balance of the mounting seat 10 is kept. The support structure 101 of the present invention is not limited to the configuration shown in fig. 1, and for example, the number of the brackets 1011 is not limited to four, and may be more, three, or two, and the installation position of the support structure may be appropriately changed according to actual needs, and the shape of the brackets 1011 and the cross bars 1012 may be a rectangular cross section, or may be circular, elliptical, irregular, or the like.

As shown in fig. 1, the housing 102 is cylindrical, and the housing 102 has a first opening 1021 for receiving a flower and a lid 1022 for covering the first opening 1021 in the upper part, and has a second opening 1023 in the lower part communicating with the opening of the receptacle 103. A collecting port 1024 for collecting the treated flowers is formed in the circumferential surface of the housing 102. As shown in fig. 2, the housing 102 houses the cutting mechanism 20, the adjustment mechanism 30, and the acquisition mechanism 40. Further, in the height direction (hereinafter, also referred to as the first direction) of the branch and leaf cutter 1, as shown in fig. 2, the collecting mechanism 40 is provided above the cutting mechanism 20, and the adjusting mechanism 30 is provided across the cutting mechanism 20. A spacer 1025 is fixed to the inner wall of the housing 102. The isolation net unit 1025 is a circular net-shaped plate having a plurality of meshes, and has a diameter slightly smaller than the housing 102. An isolation net section 1025 is disposed between the cutting mechanism 20 and the harvesting mechanism 40.

The cover 1022 is attached to the first opening 1021 by a hinge, and the cover 1022 is closed when the branch and leaf cutting device 1 is operating, so that the splash of the waste chips and the like can be prevented. Also, the cover 1022 may be formed of a transparent material to facilitate observation of the operation of the branch and leaf cutting apparatus 1. Further, a collector for receiving the processed flower (flower part from which branches and leaves are cut) may be provided at the collection port 1024.

The receiving portion 103 is formed in a bag shape, is fixedly attached to the housing 102, and receives a cut branch or leaf. The opening of receiving portion 103 is substantially the same in size as second opening 1023 of housing 102, and has a shape closed outside the opening communicating with second opening 1023. It is understood that the receiving portion 103 may be formed of a net of a knitted fabric or may be formed of a transparent plastic material, but is not limited thereto, and may be formed so that branches and leaves cut in the receiving portion 103 can be easily observed. The shape of the receiving portion 103 may be cylindrical, hemispherical, tapered, polygonal, or irregular, but may be arbitrarily set, and the receiving portion 103 may be detachably attached to the housing 102 in a manner of silicone fitting, screw fastening, engagement, magnetic attraction, or drawing, and is not particularly limited.

Next, the structure of the cutting mechanism 20 will be specifically described with reference to fig. 2 and 3. The cutting mechanism 20 includes a support bracket 201, a first driving portion 202, a connecting shaft 203, fan blades 204, and a cutting portion 205.

The support frame 201 is fixed to the inner wall of the housing 102, and in the present embodiment, the support frame 201 is a cross structure formed by two intersecting bars, and the support frame 201 is provided with four adjustment portions 2011, which can adjust the mounting positions of the respective ends of the two bars, thereby adjusting the angle and height of the entire cutting mechanism 20 mounted on the support frame 201.

The first driving unit 202 is fixed to a central portion of the supporting frame 201. The first driving part 202 includes a motor, which may be a servo motor, a speed-adjustable motor, or the like, and the first driving part 202 may further include a control device connected to the motor and used for supplying power, adjusting speed, adjusting direction, timing, or the like.

The upper end of the connecting shaft 203 is separated from the insulating mesh part 1025 of the case 102, and the lower end of the connecting shaft 203 is connected to the driving shaft of the first driving part 202. The connection shaft 203 includes a rotating portion 2031 and a fixing portion 2032. The fan blade 204 and the cutting portion 205 are fixed to the rotating portion 2031 of the connecting shaft 203, respectively, and the cutting portion 205 is located below the insulating mesh portion 1025 and above the fan blade 204. The rotation center axis of the rotation portion 2031 of the connection shaft 203 coincides with the drive shaft of the first drive portion 202. Thus, the cutting unit including at least the connecting shaft 203 and the cutting portion 205 is movably connected to the driving shaft of the first driving portion 202, and the connecting shaft 203, the fan blades 204, and the cutting portion 205 are synchronously rotated by the driving of the first driving portion 202, so that the leaves on the barrier net portion 1025 are blown to the lower socket portion 103 by the fan blades 204, and the cutting portion 205 below the barrier net portion 1025 cuts the leaves, and the cut leaves can be blown to the lower socket portion 103 by the fan blades 204 without being splashed.

The fixing portion 2032 is located below the fan blades 204 and above the first driving portion 202. The fixing portion 2032 is sleeved on the periphery of the rotating portion 2031, and can rotate without following the rotation of the rotating portion 2031, and the fixing portion 2032 is linked with the rotating portion 2031. That is, on the rotation center axis of the connection shaft 203, the relative positions of the fixing portion 2032 and the rotating portion 2031 are not changed, and when the fixing portion 2032 moves, the rotating portion 2031 moves together, and thus the cutting unit including the cutting portion 205 also moves together. Fig. 4 specifically shows the structure of the fixing portion 2032. As shown in fig. 4, the fixing portion 2032 includes a protrusion T and a positioning hole H. The fixing portion 2032 is defined to be movable only in the first direction and to be able to maintain the balance of the cutting portion 205 by including the protrusion T and the positioning hole H. The number of the positioning holes H may be one or more. The protrusion T protrudes outward from the outer circumference of the fixing portion 2032, and it is understood that the protrusion T may be a screw protrudingly fixed to the outer circumference of the fixing portion 2032 or may be a part of the fixing portion 2032 integrally formed. The positioning hole H penetrates the fixing portion 2032 in a direction parallel to the rotation center axis of the connection shaft 203, that is, in the first direction. Accordingly, the fixing portion 2032 can be restricted to move in the first direction, and the height of the cutting portion 205 can be adjusted.

The fan blades 204 include a plurality of blades (3 blades in fig. 3), and are driven by the first driving portion 202 to generate a downward wind, so that the cut branches and leaves are sucked downward and received by the receiving portion 103 at the lowermost end of the mount 10. In the present invention, the number and shape of the blades of the fan blade 204 are not particularly limited.

The cutting portion 205 includes a plurality of blades (5 blades in fig. 3), and is formed in a disk shape as a whole and has a certain rigidity in order to prevent the blades from being deformed. In addition, the shape of the blade is not particularly limited in the present invention.

Next, the structure of the adjustment mechanism 30 will be specifically described with reference to fig. 2, 3, 5, 6, 7, and 8. The adjusting mechanism 30 comprises a handle 301, a transmission 302 and an adjusting component 303.

As shown in fig. 3, the handle 301 includes a knob 3011 attached to the outside of the housing 102 and a torsion bar 3012 penetrating the housing 102, and the knob 3011 is connected to the torsion bar 3012. The torsion bar 3012 is actuated by turning the knob 3011. Since the handle 301 is attached to the outside of the housing 102, the height of the cutting portion 205 can be adjusted from the outside by the handle 301.

The transmission part 302 is a flexible shaft which is a shaft with small rigidity, elasticity and free bending transmission and can flexibly transmit rotary motion and torque to any position. As shown in fig. 3, the transmission portion 302 has a first transmission end 3021 and a second transmission end 3022, and as shown in fig. 7, one end of the torsion bar 3012 is connected to the knob 3011, and the other end is connected to the first transmission end 3021, so that the first transmission end 3021 is rotated by rotating the knob 3011 in accordance with the rotation of the rotation knob 3011. On the other hand, the second transmission end 3022 is connected to the adjustment assembly 303 by, but not limited to, snap-fitting, screwing, welding, etc. In the power transmission portion 302, the rotation of the first power transmission end 3021 is transmitted to the second power transmission end 3022, and when the second power transmission end 3022 rotates, the second power transmission end 3022 can extend and contract due to the rotation and drive the adjusting assembly 303, so that the position of the adjusting assembly 303 is changed. In this embodiment, as shown in fig. 3 and 8, the transmission portion 302 further includes a transmission end mounting portion 3023, the transmission end mounting portion 3023 is fixed relative to the housing 102, a thread is disposed on the second transmission end 3022, a threaded hole is disposed on the transmission end mounting portion 3023, and the second transmission end 3022 is mounted in threaded fit with the transmission end mounting portion 3023, so that when the second transmission end 3022 rotates, the second transmission end 3022 extends and retracts relative to the transmission end mounting portion 3023, and simultaneously drives the adjusting assembly 303, thereby changing the position of the adjusting assembly 303.

Thus, through the transmission of the torque of the transmission part 302, the operator can rotate the second transmission end 3022 by using the knob 3011 from the outside, and the rotation of the second transmission end 3022 drives the adjusting assembly 303 connected with the second transmission end 3022, thereby changing the position of the adjusting assembly 303. It is to be understood that the structure of the transmission portion 302 is not limited thereto as long as it can appropriately transmit the external force to the adjustment assembly 303.

As shown in fig. 2 and 3, the adjusting assembly 303 includes an adjusting portion 3031 and an adjusting portion fixing bracket 3032 for mounting the adjusting portion 3031 to the cutting mechanism 20, and the adjusting portion 3031 is used for adjusting the height of the cutting portion 205 in the cutting mechanism 20.

The adjustment part holder 3032 is fixed to the support bracket 201 and is thereby fixed to the housing. Further, the transmission end mounting portion 3023 described above is mounted on the adjustment portion holder 3032. As shown in fig. 5, the adjustment part holder 3032 has a substantially "zigzag" shape, and the adjustment part holder 3032 has a guide surface G1 and a positioning post G2 extending perpendicularly to the guide surface G1. The adjustment part holder 3032 extends across the first drive part 202 and accommodates the first drive part 202 in the inside of the zigzag shape. The guide surface G1 is located below the fixing portion 2032 and guides the adjusting assembly 303 to move along the second direction. The positioning post G2 is fixedly connected to the guiding surface G1 and limits the fixing portion 2032 to move along the first direction.

In addition, the positioning hole H of the fixing portion 2032 is movably sleeved on the positioning post G2, so that when the height of the cutting portion 205 is adjusted, the positioning structure formed by the positioning hole H and the positioning post G2 enables the fixing portion 2032 to move relative to the adjusting portion fixing frame 3032 without deviation, thereby adjusting the height of the cutting portion 205 without deviation.

The fixing portion 2032 provided with the positioning hole H can be guided to move in the first direction by the positioning column G2 provided in the first direction. The positioning posts G2 may be appropriately changed according to the arrangement of the positioning holes H.

It is understood that when there are a plurality of positioning holes H, there is no particular limitation as long as the positioning holes H and the corresponding positioning columns G2 are uniformly distributed around the central axis of the fixing portion 2032, and the diameter of at least one positioning hole H matches the diameter of the positioning column G2. By providing at least one positioning hole H having a diameter matching the diameter of the positioning post G2, the cutting portion 205 can be surely prevented from being inclined in the left-right direction during operation and adjustment, and excellent balance can be obtained while adjusting the height with a simple structure.

It is to be understood that the positioning holes H may be two through holes uniformly distributed on both sides of the rotation center axis along a direction parallel to the rotation center axis of the connecting shaft 203 (i.e., the first direction), or may be three through holes distributed at three end points of an equilateral triangle centering on the rotation center axis, as long as the positioning holes H are uniformly distributed centering on the rotation center axis. Preferably, two positioning holes H and two corresponding positioning posts G2 and two corresponding protrusions T are arranged, and a line connecting the positioning holes H and a line connecting the protrusions T are orthogonal to each other on a plane perpendicular to the first direction, so that the dicing portion 205 can be moved in the first direction without being inclined, and excellent balance can be obtained with a simple configuration.

As shown in fig. 6, the adjustment portion 3031 has a frame shape having four sides, and the four sides are perpendicular to the guide surfaces G1 of the adjustment portion holder 3032, respectively. The first surface 3031a is opposed to the second surface 3031b, and a third surface 3031c and a fourth surface 3031d opposed to each other are provided between the first surface 3031a and the second surface 3031 b. The first surface 3031a is a surface connected with the second transmission end 3022 of the transmission part 302 and is a force-bearing surface on which the second transmission end 3022 exerts force on the adjustment part 3031, so that preferably the first surface 3031a is perpendicular to the second direction in which the adjustment part 3031 moves, and the fourth surface 3031d are parallel to the second direction. In addition, an angle of the second face 3031b facing the first face 3031a is not particularly limited. Assuming that the first surface 3031a is connected with the second transmission end 3022 in a snap-fit manner, a groove (not labeled) may be provided on the first surface 3031a, and a protrusion or a snap-fit or the like which is matched with the groove may be correspondingly provided on the end of the second transmission end 3022. In addition, guide grooves a and b are respectively provided at the bottom of the first surface 3031a and the second surface 3031b opposite to the first surface 3031a, and the guide grooves a and b are movably connected with respect to the guide surface G1 of the adjustment part holder 3032. Thus, when the actuator 302 moves the adjustment part 3031, the adjustment part 3031 can move in the second direction without tilting. Preferably, the guide grooves a and b of the adjustment portion 3031 are configured to engage with the guide surface G1 of the adjustment portion holder 3032. Further, the third surface 3031c and the fourth surface 3031d which face each other are provided with symmetrical stopper portions c and d. The stopper portions c and d are elongated shapes inclined from the third surface 3031c toward the fourth surface 3031d, and may be, for example, long holes, slide rails, concave grooves, or the like that engage with the convex portions T and move, and the predetermined direction may be set as appropriate in a direction between the first direction and the second direction (i.e., a direction intersecting the first direction and the second direction). The protrusion T of the fixing portion 2032 is movably disposed in the limiting portions c and d, so that the fixing portion 2032 and the adjusting portion 3031 move relative to each other along the limiting portions c and d. It is to be understood that the shape of the four surfaces is not particularly limited as long as the guide grooves, the stopper portions, the connection with the second transmission end, and the like can be appropriately provided.

In the present embodiment, the stoppers c and d shown in fig. 6 have a long hole shape which is gradually inclined downward from the first surface 3031a side toward the second surface 3031b on the third surface 3031c and the fourth surface 3031d. Thus, when the second transmission end 3022 is extended by rotating relative to the transmission end mounting portion 3023, the adjustment assembly 303 is pushed to move in the second direction, and the convex portion T provided in the stopper portions c, d cannot obtain a displacement in the second direction because it is restricted to move only in the first direction, and therefore, the convex portion T gradually moves upward from the first surface 3031a side toward the second surface 3031b relative to the stopper portions c, d, and the convex portion T moves only in the first direction; on the other hand, when the second transmission end 3022 is retracted by rotating relative to the transmission end mounting portion 3023, the adjustment assembly 303 is pulled back so as to move in the second direction, and the convex portion T provided in the stopper portions c and d cannot obtain a displacement in the second direction because it is restricted to move only in the first direction, and therefore the convex portion T gradually moves downward from the first surface 3031a side toward the second surface 3031b relative to the stopper portions c and d, and the convex portion T moves downward only in the first direction. Accordingly, since the relative position of the fixing portion 2032 including the convex portion T and the rotating portion 2031 is not changed, the cutting portion 205 can be also moved by the fixing portion 2032, and the height can be changed, whereby the distance of the cutting portion 205 from the partition net portion 1025 can be adjusted.

It is to be understood that the inclined long holes of the stopper portions c, d may also be provided in a shape that gradually inclines upward from the first surface 3031a side toward the second surface 3031b, in which case the convex portion T moves downward in the first direction relative to the inclined long holes when the adjustment member 303 is pushed, and on the other hand, moves upward in the first direction relative to the inclined long holes when the adjustment member 303 is pulled.

It will be appreciated that the structure of the adjustment assembly 303 is not limited thereto, as long as it can properly receive the force of the transmission portion 302 and properly transmit the force to the cutting portion 205. The process of force transmission in the present embodiment is specifically described below.

In operation, an operator rotates the second driving end 3022 by the knob 3011 from the outside, and pushes or pulls the adjusting assembly 303 connected to the second driving end 3022 by the displacement generated by the rotation of the second driving end 3022. Accordingly, the adjusting unit 303 is moved by receiving a force in the second direction, and since the connecting shaft 203 is connected to the driving shaft of the first driving unit and the stoppers c and d of the adjusting unit 303 abut against the protrusion T of the fixing portion 2032, when the adjusting unit 303 is moved, a force of the protrusion T in the first direction other than the force generated by the abutment is restricted by the positioning hole H and the positioning post G2, and a force in the first direction remains, whereby the protrusion T of the fixing portion 2032 is moved relative to the stoppers c and d of the adjusting unit 303 and the protrusion T of the fixing portion 2032 is moved only in the first direction or downward along the positioning post G2.

However, in the present invention, the process of transmitting the force is not limited to this, and the external force may be appropriately transmitted to the cutting portion 205 of the cutting mechanism 20 to obtain the force capable of adjusting the height.

Further, it is understood that the second direction of the above-described embodiment is a direction perpendicular to the first direction, but the present invention is not limited thereto, and the second direction may also be a direction intersecting the first direction, in which case the direction of the stopper portion in the adjusting portion 3031 may be a hole extending in a direction between the second direction and the first direction.

It should be understood that the limiting portions c, d and the protrusion T are not necessarily provided on the fixing portion 2032 of the adjusting unit 303 and the connecting shaft 203, respectively, but may be reversed. In addition, the limiting parts c and d and the convex part can also be arranged in the form of a groove and a slide block. In addition, it should be understood that the positioning column G2 and the positioning hole H are not necessarily disposed on the fixing portion 2032 of the adjusting assembly 303 and the connecting shaft 203, but may be reversed. The shape of the stopper portion and the shape of the convex portion may be any shape as long as they are fitted to each other.

The collecting mechanism 40 is provided above the cutting mechanism 20, and collects flowers whose branches and leaves are cut by the cutting unit 205. As shown in fig. 1 and 2, the picking mechanism 40 includes a second driving section 401 and a picking section 402. The second driving section 401 drives the rotation of the pickup section 402. The driving of the second driving unit 401 can be performed independently of the driving of the first driving unit 202. The second driving part 401 includes a motor, which may be a servo motor, a speed-adjustable motor, or the like, and the second driving part 401 may further include a control device connected to the motor and used for supplying power, adjusting speed, adjusting direction, timing, or the like. Collection portion 402 can adopt the silica gel preparation that has the compliance, sets up to the top of keeping apart net part 1025, and contains a plurality of silica gel fingers of perpendicular to keep apart net part 1025 to collection portion 402 can help the branch and leaf part of flowering branch to the cutting portion 205 when the cutting, and can stir the flower that has handled and draw in to collecting the mouth.

According to one aspect of the present embodiment, by providing the adjustment mechanism 30 connected to the cutting mechanism 20, the height of the cutting portion 205 can be appropriately adjusted, and trimming can be performed in response to the needs of different types of flowers.

Further, by providing the transmission unit 302, the force from the outside of the housing 102 can be transmitted to the inside with a simple mechanical structure, and the height of the cutting unit 205 can be adjusted from the outside without detaching the mounting base 10, which brings convenience to the operability.

Further, by providing the guide grooves a and b and the guide surface G1 in the adjustment mechanism 30, it is possible to avoid imbalance in height adjustment due to imbalance in movement when moving the adjustment mechanism 30.

Moreover, by further arranging the stressed first surface 3031a to be perpendicular to the force application direction of the second transmission end 3022 of the force application transmission portion 302, the unnecessary force loss can be reduced, the labor can be saved when the operator operates from the outside, and good force feedback can be obtained, so that the blade height can be adjusted more accurately.

Further, by providing the stopper portions c and d in the adjustment mechanism 30 and forming holes in the stopper portions c and d obliquely in the direction between the moving direction and the height direction of the adjustment mechanism 30, it is possible to further reduce the loss of unnecessary force and to obtain better force feedback.

Further, by providing the positioning column G2 and the positioning hole H, the cutting portion 205 is prevented from being inclined in the left-right direction during operation and adjustment, and excellent balance is obtained.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
