Description

Technical Field

[0001] The utility model relates to the technical field of tea picking machines, in particular to tea picking auxiliary equipment. Background Art

[0002] Tea picking machine is a crop harvesting machine that collects new tender tea leaves from the tops of tea trees. Tea picking machines include: reciprocating cutting tea picking machine, hook knife cutting tea picking machine, spiral rolling cutting tea picking machine, riding tea picking and pruning all-in-one machine, etc. Among them, the reciprocating cutting tea picking machine is driven by a small gasoline engine of 0.6 to 14 watts or a micro motor of about 40 watts. The power is transmitted to the hand-held picking device by a flexible shaft, driving the cutter (there are two types: double-moving knife and single-moving knife) to do reciprocating motion to achieve the picking of tea leaves. Compared with traditional manual picking of tea leaves, its work efficiency is higher.

[0003] The hand-held part of the existing reciprocating cutting tea plucking machine is fixed. Therefore, when the reciprocating cutting tea plucking machine is held for picking tea leaves, the arm posture remains in the same posture for a long time, which will cause increased fatigue in the wrist. If different hand-held postures can be selected during use, wrist fatigue can be effectively relieved. Based on this, a tea picking auxiliary device is provided. Utility Model Content

[0030] See also Figures 1 to 4In an embodiment of the utility model, a tea picking auxiliary device includes a tea picking machine 1 composed of a tea collecting bucket 101, a connecting arm 102, a casing body 103, a fixed blade 104, and a reciprocating blade 105. The casing body 103 is fixedly connected to one end of the tea collecting bucket 101 through the connecting arm 102, the fixed blade 104 is fixedly installed at the bottom of the opening of the tea collecting bucket 101, and the reciprocating blade 105 is distributed at the bottom of the fixed blade 104 and passes through the connecting arm 102 to the inside of the casing body 103. The output end of the driving device inside the casing body 103 is transmission-connected with the reciprocating blade 105, which is used to drive the reciprocating blade 105 to move back and forth. A handle assembly 2 is provided on the top of the casing body 103 near one end of the tea collecting bucket 101, and the handle assembly 2 is used to provide a gripping position for tea pickers;

[0031] The handle assembly 2 includes a gripping unit, an adjusting unit, and a control unit. The gripping unit is used to enable the tea pickers to grip the tea picker 1. The adjusting unit is used to adjust the angle of the gripping unit to enable the tea pickers to grip in different postures. The control unit is used to control the opening and closing of the driving device inside the casing body 103.

[0032] The gripping unit includes a fixing seat 201, a rotating slot 202, a rotating block 203, and a handle 204;

[0033] The fixing seat 201 is fixed to one end of the top of the casing body 103 close to the tea collecting 101, and the rotating groove 202 is opened at one end of the fixing seat 201 close to the tea collecting 101 and passes through the upper and lower ends of the fixing seat 201;

[0034] The rotating block 203, the handle 204, and the limiting circular block 205 are fixed in sequence along the horizontal direction. The rotating block 203 is rotatably connected to the inner side of the rotating groove 202, and the handle 204 is used to provide a gripping position for tea pickers.

[0035] The adjustment unit includes an arc groove 206, an annular tooth groove 207, an annular groove 208, a collar 209, a sleeve 210, a locking block 211, and a return spring 212;

[0036] The arc grooves 206 are symmetrically distributed around the rotating groove 202 and are opened at one end of the fixed seat 201 close to the tea collection 101. The annular tooth grooves 207 are formed on the inner wall arc end surface of the arc grooves 206.

[0037] The annular groove 208 is formed on the outer side of the end of the handle 204 close to the rotating block 203, the collar 209 and the return spring 212 are sleeved on the outer side of the annular groove 208, and the return spring 212 is distributed on the end of the collar 209 away from the rotating block 203;

[0038] The sleeve 210 is fixed to the outside of the collar 209 and covers the annular groove 208 area. The locking block 211 is symmetrically fixed to one end of the sleeve 210 close to the rotating block 203, and the locking block 211 is clamped inside the arc groove 206. The end surface of the locking block 211 is formed with a tooth block that is clamped with the annular tooth groove 207.

[0039] The locking block 211 is separated from the annular tooth groove 207 to unlock the position of the handle 204, which is used to achieve rotation adjustment of the handle 204. The position of the handle 204 is fixed by the engagement of the locking block 211 with the annular tooth groove 207, and the rotation adjustment of the handle 204 is used to achieve different gripping postures for tea pickers;

[0040] One end of the handle 204 away from the rotating block 203 is fixedly connected to a limiting circular block 205, and the outer diameter of the limiting circular block 205 is larger than the outer diameter of the handle 204. When the handle 204 is rotated in a vertical state, the limiting circular block 205 is used to limit the upper part of the hand grasping the handle 204 to prevent the hand from slipping.

[0041] In this embodiment, when the tea plucking machine 1 is used daily, the handle 204 is in a horizontal alignment with the fixed seat 201, which is the same as the hand-holding posture of the traditional tea plucking machine 1. After plucking tea for a period of time, when the wrist feels tired due to the fixed posture, the angle of the handle 204 can be adjusted to adjust the hand-holding posture. By adjusting the hand-holding posture, the effect of relieving wrist fatigue can be achieved. The operation steps are as follows:

[0042] The sleeve 210 is manually pushed to move away from the rotating block 203, and the sleeve 210 drives the collar 209 to squeeze the return spring 212 to further shrink and deform. At the same time, the sleeve 210 drives the locking block 211 to move, so that the end face tooth block of the locking block 211 is separated from the annular tooth groove 207, thereby releasing the fixation of the handle 204 (it should be noted that at this time, the locking block 211 is still located inside the arc groove 206 and has not completely fallen off the arc groove 206);

[0043] The handle 204 can then be rotated so that the handle 204 rotates around the rotation point of the rotating block 203. When the handle 204 is rotated upward to the required angle (for example: 90 degrees vertically), the push on the sleeve 210 can be released. At this time, the ring 209, sleeve 210, and locking block 211 will quickly reset under the reset elastic force of the reset spring 212, and the end face tooth block of the locking block 211 will be stuck in the annular tooth groove 207 at the corresponding position, thereby fixing the position of the handle 204.

[0044] Please refer to Figures 1 to 4 , the control unit includes a switch button 213, a wire 214, and a through hole 215;

[0045] The switch button 213 is installed on one side of the handle 204 and is located at one end of the handle 204 close to the limiting round block 205. The through hole 215 is opened at one end of the inner wall of the rotating groove 202 and penetrates into the inside of the housing body 103 to communicate with the inner cavity of the housing body 103.

[0046] The switch button 213 passes through the handle 204 , the rotating block 203 , the through hole 215 in sequence to the inner cavity of the housing body 103 through the wire 214 , and is electrically connected to the controller of the driving device inside the housing body 103 .

[0047] In this embodiment: through this structure, during the rotation and adjustment of the handle 204, the switch button 213 and the controller of the internal drive device of the casing body 103 can maintain a stable electrical connection state, and the opening and closing of the internal drive device of the casing body 103 can be controlled by the switch button 213.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
