Description

Technical Field

[0001] The utility model relates to the technical field of tea plucking machines, in particular to an adjustable cutting device and a tea plucking machine with the adjustable cutting device. Background Art

[0002] Some existing electric tea plucking machines (such as the electric tea plucking machine disclosed in CN102783309A) generally cut the top of the tea tree by controlling the blade to move back and forth through a DC motor, thereby achieving the purpose of automatic operation.

[0003] However, this type of electric tea plucking machine has a fixed position during use and cannot be adjusted accordingly according to the growth conditions of the tea trees, resulting in poor versatility. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an adjustable cutting device and a tea plucking machine with the adjustable cutting device, which can adapt to tea trees at different positions and heights for automatic operation.

[0005] The utility model is achieved through the following technical solutions:

[0006] The utility model provides an adjustable cutting device, comprising a cutting mechanism and an adjusting mechanism connected to the cutting mechanism and capable of adjusting the height and angle of the cutting mechanism, wherein the adjusting mechanism comprises a height adjusting component and an angle adjusting component;

[0007] The height adjustment assembly includes a lifting seat and a lifting drive, wherein the lifting drive is connected to the lifting seat and can drive the lifting seat to move up and down;

[0008] The angle adjustment assembly includes a support, a rocker arm, a pull rod, a connecting rod and a rotating shaft. The support is fixed on the lifting seat. The rocker arm and the connecting rod are respectively threadedly connected to the two ends of the pull rod. The end of the rocker arm away from the pull rod is rotatably connected to the support. The end of the connecting rod away from the pull rod is rotatably connected to the rotating shaft. The rotating shaft is connected to the cutting mechanism. Rotating the pull rod can drive the pull rod to move and drive the rotating shaft to rotate, thereby realizing the angle adjustment of the cutting mechanism.

[0009] In order to facilitate the lifting and lowering of the entire adjusting mechanism, in a preferred embodiment of the present utility model, the lifting drive includes a handle, a screw rod and a guide rod. The lifting seat is slidably connected to the guide rod and connected to the screw rod. The handle is connected to the screw rod. The handle can drive the screw rod to rotate, thereby driving the lifting seat to move up and down.

[0010] In order to facilitate the cutting action, in a preferred embodiment of the present invention, the cutting mechanism includes a bracket, a knife holder, a blade and a motor. One end of the bracket is connected to the support, and the other end of the bracket extends away from the support. The knife holder is fixed on the bracket, and the blade is arranged in the knife holder and connected to the motor. The motor can drive the blade to move.

[0011] In order to facilitate the rotation of the bracket, one end of the bracket is rotatably connected to the lifting seat through a rotating rod.

[0012] Since the middle height of a tea tree is generally higher than the two ends, in order to improve the quality and efficiency of tea picking, the knife holder is an arc-shaped long strip structure, and the height of the two ends is lower than the middle height.

[0013] In order to facilitate the collection of cut branches and leaves, a number of air blowing pipelines are provided above the knife holder.

[0014] The utility model also provides a tea plucking machine, comprising a tea plucking machine body capable of automatically moving, wherein the adjustable cutting device is installed on the tea plucking machine body.

[0015] The beneficial effect of the utility model is that the adjustable cutting device and the tea picking machine can be adjusted accordingly according to the height and distribution position of the tea leaves through a specially designed adjustment mechanism, the adjustment is flexible and convenient, and the versatility is strong, thereby greatly improving the effectiveness and efficiency of tea picking.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Example 1:

[0022] like Figure 1An adjustable cutting device is shown, comprising a cutting mechanism 3 and an adjusting mechanism connected to the cutting mechanism 3 and capable of adjusting the height and angle of the cutting mechanism 3. The adjusting mechanism comprises a height adjusting component 1 and an angle adjusting component 2. The height adjusting component 1 can control the raising and lowering of the cutting mechanism 3 to adjust its height to cope with tea trees in different environments. The angle adjusting component 2 can control the cutting mechanism 3 to deflect to the left or right by a certain angle, thereby improving the effectiveness of cutting.

[0023] Specifically, combined Figure 2 The height adjustment assembly 1 shown includes a lifting seat 104 and a lifting drive. The lifting drive includes a handle 101, a screw rod 102 and a guide rod 103. The lifting seat 104 is slidably connected to the guide rod 103 and connected to the screw rod 102. The handle 101 is connected to the screw rod 102. The handle 101 can drive the screw rod 102 to rotate, thereby driving the lifting seat 104 to move up and down.

[0024] Specifically, combined Figure 3 As shown, the angle adjustment assembly includes a support 201, a rocker arm 202, a pull rod 203, a connecting rod 204 and a rotating shaft 205. The support 201 is fixed on the lifting base, and the rocker arm 202 and the connecting rod 204 are respectively threadedly connected to the two ends of the pull rod 203. The end (rear end) of the rocker arm 202 away from the pull rod 203 is rotatably connected to the top of the support 201, and the end (front end) of the connecting rod 204 away from the pull rod 203 is rotatably connected to the rotating shaft 205. The rotating shaft 205 is connected to the cutting mechanism. The pull rod 203 is fixed with a handle 206 that facilitates its rotation.

[0025] Specifically, the cutting mechanism includes a bracket 301, a knife holder 304, a blade 302 and a motor 303. One end (rear end) of the bracket 301 is rotatably connected to the support 201 through a rotating rod 305, and the other end (rear end) of the bracket 301 extends away from the support 201. The knife holder 304 is fixed to the bottom end of the bracket 301. The knife holder 304 is an arc-shaped long strip structure, and the height of its two ends is lower than the middle height. The blade 302 is arranged in the knife holder 304 and is connected to the motor 303. In addition, a number of air blowing pipes 306 are arranged above the knife holder 304, and the air blowing pipes 306 are connected to the air system through a main pipeline.

[0026] During use, the lifting seat 104 is raised and lowered to a fixed position by rotating the handle 101, thereby lowering the cutting mechanism 3 to a corresponding height, and then the pull rod 203 is rotated. Since the pull rod 203 is threadedly connected to the rocker arm 202 and the connecting rod 204, the pull rod 203 can pull or push the connecting rod 204, and the rocker arm 202 can swing up and down, driving the cutting mechanism 3 to flip upward or downward as a whole, and its angle can be adjusted so that it fits with the top of the tea tree. At this time, the motor 303 drives the blade 302 to move to perform the operation, and each air blowing pipe 306 can blow air, thereby facilitating the collection of cut branches and leaves.

[0027] Example 2:

[0028] This embodiment provides a tea picking machine, such as Figure 4 As shown, it includes a tea plucking machine body A that can move automatically, and the above-mentioned adjustable cutting device B is installed on the tea plucking machine body A. The tea plucking machine body A drives the adjustable cutting device B to move to realize automated tea plucking operations.
