[0011] The following is combined with Figure 1-4 And related content, the utility model is further described in detail:

[0012] A tea tree pruning and harvesting machine, wherein a traveling mechanism 11 is arranged at the bottom of a vehicle body 10, a fixed frame 30 is provided at the front end of the vehicle body 10, the frame surface of the fixed frame 30 is arranged vertically and the frame surface is perpendicular to the traveling direction of the traveling mechanism 11, a movable frame 40 is provided on the fixed frame 30, and a driving mechanism 50 for driving the movable frame 40 to move up and down is provided between the two, and a cutting mechanism 20 is provided at the lower end of the movable frame 40, and the cutting mechanism 20 is arranged along the vehicle width direction.

[0013] In the above scheme, the tea tree pruning and harvesting machine uses the walking mechanism 11 to move, and the cutting mechanism 20 located at the front end of the body 10 cuts the branches of the tea tree while moving with the body 10. Among them, the cutting mechanism 20 is connected to the movable frame 40 on the fixed frame 30 at the front end of the body 10, and the driving mechanism 50 can drive the movable frame 40 and the cutting mechanism 20 at the lower end to move up and down together. According to the different cutting height requirements of the tea tree, the height position of the cutting mechanism 20 is adjusted, and the height of its cutting position can be dynamically adjusted to cut the tea tree, meet the cutting requirements of tea branches or tea leaves at different heights, and it is more flexible and convenient to use.

[0014] It should be noted that, in the present embodiment, the cutting mechanism 20 is a pair of shaving scissors.

[0015] As a preferred solution, the fixed frame 30 includes a fixed frame upper beam 32 and a fixed frame lower beam 31 arranged at a vertical interval, the left and right ends of the fixed frame upper beam 32 and the fixed frame lower beam 31 are connected to the upper and lower ends of the left and right columns 33A and 33B arranged vertically, the left and right columns 33A and 33B are guide grooves 34 arranged opposite or opposite to each other by channel steel, and the left and right uprights 41 of the movable frame 40 form a limit guide match with the guide groove 34. The driving mechanism 50 can drive the movable frame 40 to move up and down along the guide groove 34, and the guide groove 34 guides the movement of the uprights 41 to ensure that the movable frame 40 moves up and down relative to the fixed frame 30 more stably.

[0016] Furthermore, the movable frame 40 includes the limiting wheels arranged on the left and right uprights 41, which are in rolling cooperation with the bottom and wall of the guide groove 34, and the notches of the guide groove 34 on the left and right uprights 33A and 33B are arranged relatively. The limiting wheels on the uprights 41 can roll along the guide groove 34 inside thereof, and the uprights 41 do not directly contact the groove body of the guide groove 34. The upward and downward movement of the movable frame 40 relative to the fixed frame 30 is smoother, and the uprights 41 and the guide groove 34 are prevented from scratching each other, and the lifting and lowering adjustment process of the cutting mechanism 20 is smoother.

[0017] As a preferred solution, the guide groove 34 is arranged vertically in the groove length direction, and a rolling wheel 44 is arranged on the vertical rod 41. The wheel core of the rolling wheel 44 is located in the horizontal direction and parallel to the groove wall of the guide groove 34. The rolling wheel 44 is located in the guide groove 34 and at least two rolling wheels 44 are arranged up and down and form a rolling match with the groove wall of the guide groove 34. The rolling wheel 44 rolls on the groove wall of the guide groove 34. By setting the direction of its wheel core, the vertical rod 41 and the movable frame 40 can be limited to relative displacement relative to the fixed frame 30 in the direction of travel of the vehicle body 10.

[0018] In addition, brackets 45 are connected to the left and right uprights 41, and rollers 46 are arranged on the brackets 45. The wheel core of the rollers 46 is located in the horizontal direction parallel to the bottom of the guide groove 34 and forms a rolling fit with the outer wall surface of the bottom of the guide groove 34. The rollers 46 can roll on the outer wall surface of the bottom of the guide groove 34. Through the arrangement of the rollers 46 on the left and right uprights 41, the relative displacement of the uprights 41 and the movable frame 40 as a whole relative to the fixed frame 30 in the vehicle width direction can be limited.

[0019] In the above-mentioned cooperation scheme of the rolling wheel 44 and the roller 46, the rolling wheel 44 and the roller 46 respectively limit the movable frame 40 in the travel direction and the width direction of the vehicle body 10 to prevent the movable frame 40 from tipping over relative to the fixed frame 30, thereby ensuring the stability of the relative movement of the movable frame 40 on the fixed frame 30.

[0020] Furthermore, the vertical pole 41 is composed of a lower end of a vertical plate 412 located at the upper part and an upper end of a square steel pipe column 411 located at the lower part. The plate surfaces of the left and right vertical plates 412 are parallel to each other and parallel to the driving direction of the vehicle body 10. The rolling wheels 44 and the rollers 46 are arranged on the outer plate surfaces of the lower middle section and the lower end of the left and right vertical plates 412.

[0021] Combination Figure 2 , 4 As shown, an upper crossbeam 42 is arranged between the upper ends of the left and right upright plates 412, a middle crossbeam 43 and a lower crossbeam 47 are arranged between the upper and lower ends of the left and right square steel pipe columns 411, the lower end width of the left and right upright plates 412 is greater than the upper end width, and the rear side plate edge of the upright plates 412 is a straight edge in the plumb direction, and the front side plate edge of the upright plates 412 is an arc edge or a folded edge, and the lower part of the frame of the movable frame 40 formed by the left and right square steel pipe columns 411 and the middle crossbeam 43 and the lower crossbeam 47 is located on the front side of the fixed frame 30 and arranged adjacently. The lower part of the frame of the movable frame 40 avoids the fixed frame 30, and when the driving mechanism 50 drives the movable frame 40 to move up and down, the lower part of the frame of the movable frame 40 will not interfere with the fixed frame 30, ensuring that the cutting mechanism 20 at its lower end has a reasonable up and down movement range. At the same time, the vertical plate 412 can move up and down in the area relative to the guide groove 34, and it is also convenient to reasonably arrange the rolling wheels 44 on the vertical rod 41 to roll with the guide groove 34, so that the overall structural layout is more reasonable and stable.

[0022] In addition, the lower end of the oil cylinder body 51 constituting the driving mechanism 50 is connected to the middle of the lower cross beam 31 of the fixed frame, and the upper rod end of the piston rod 52 is connected to the middle of the upper cross beam 42, and the oil cylinder body 51 and the piston rod 52 are arranged in a plumb direction. The oil cylinder body 51 is located between the upper cross beam 42 of the movable frame 40 and the lower cross beam 31 of the fixed frame, and its upper and lower ends are connected to the middle of the two, so that the oil cylinder body 51 is located at the mass center of the movable frame 40 and the fixed frame 30 as a whole. When the driving mechanism 50 drives the movable frame 40 to move up and down, the lifting force on the movable frame 40 is more evenly distributed in the structure, so that the overall force on the movable frame 40 is more stable.
