Description

Technical Field

[0001] The utility model relates to the technical field of wolfberry planting, in particular to a wolfberry tree pruning device. Background Art

[0002] Pruning plays a crucial role in the cultivation and planting of wolfberries. First, it helps control tree vigor through pruning. Pruning can remove overgrown branches, reducing unnecessary nutrient consumption and concentrating nutrients on fruiting branches, significantly increasing fruit set. Second, it can alter the tree's shape by removing overcrowded and insect-infested branches, increasing light intensity within the canopy and ensuring the fruit receives better sunlight, thereby improving fruit quality and further reducing the incidence of pests and diseases.

[0003] There are currently two pruning methods. The first is to use an electric saw to achieve large-scale rough pruning. After pruning to a suitable tree shape, fine pruning is required based on branch density and pest control. Currently, this fine pruning is performed using gardening shears. Although wolfberry branches are relatively thin and pruning is not very laborious, for a scale of thousands of acres, repetitive labor will quickly fatigue the fingers and reduce work efficiency. For this reason, we have proposed a wolfberry tree pruning device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] See also Figure 1-6 The handheld shell 1 is provided with a swing driving structure for driving the movable scissors 2 to swing back and forth, providing the force for the reciprocating action of the movable scissors 2 when working, thereby achieving the purpose of reducing work intensity and improving work efficiency.

[0030] In the present invention, the swing drive structure includes a turntable 5 installed in the handheld shell 1, one end of the turntable 5 is installed on the handheld shell 1 through an axis, so that one end is suspended. The handheld shell 1 is also equipped with a power structure for driving the turntable 5, which is used to drive the turntable 5 to rotate. The end of the movable scissors 2 away from the blade can also be adjusted to be equipped with a connecting rod 8, that is, the suspended end of the turntable 5 is equipped with a connecting rod 8 through an axis rotation. When the turntable 5 rotates, the connecting rod 8 can swing, and one end of the connecting rod 8 is eccentrically connected to the turntable 5. Therefore, when the connecting rod 8 swings, it can pull the movable scissors 2 to swing back and forth, thereby realizing automatic trimming.

[0031] In the present utility model, the power structure includes a motor 7 installed in the handheld shell 1, and the motor 7 drives the turntable 5 to rotate through the reduction structure. When the present application is working, the motor 7 provides power, and the reduction structure reduces the speed and increases the torque to drive the turntable 5 to rotate. During operation, the inability to cut branches due to blunt scissors or thick branches is avoided. A coupling is connected between the motor 7 and the reduction structure to protect the motor 7 and increase the service life of the motor.

[0032] In the present invention, the reduction structure is a bevel gear set 6 or a worm gear set 10, both of which have a large reduction ratio. The motor 7, turntable 5 and scissors can be set in a straight line to reduce the volume of the handheld shell 1. In particular, the worm gear set 10 has a high reduction ratio and can be driven by a smaller power motor 7.

[0033] In the present invention, an adjustment slot 11 is provided at one end of the movable scissors 2 away from the blade. The adjustment slot 11 runs through the movable scissors 2. An adjustment shaft 15 is slidingly provided in the adjustment slot 11. The adjustment shaft 15 can be adjusted to different positions. The swing angles of the movable scissors 2 are different in different positions. When pruning new branches and tender buds in spring, or denser and thin buds, it can be adjusted to a small pruning range, so that other branches and buds will not be cut by mistake due to the excessive cutting width of the movable scissors 2. When pruning old branches in autumn, it can be adjusted to a position with a larger amplitude to prune thicker old branches. When making specific adjustments, an adjustment hole 13 is provided on the side wall of the movable scissors 2. The adjustment hole A screw hole is provided at the bottom of 13, and the screw hole extends into the adjusting groove 11. An adjusting screw 12 is provided in the screw hole. When adjusting, a screwdriver is inserted into the adjusting hole 13, and the adjusting screw 12 is turned to screw it into the screw hole. At this time, the adjusting shaft 15 can slide in the adjusting groove 11. A plurality of adjusting notches 14 are provided on the side of the adjusting groove 11 away from the screw hole. When the adjusting shaft 15 is adjusted to the corresponding adjusting notch 14, the corresponding adjusting screw 12 is turned, and the adjusting screw 12 is pressed against the adjusting shaft 15. The adjusting shaft 15 is stuck in the adjusting notch 14, and the adjusting shaft 15 is locked and positioned. The connecting rod 8 is rotatably connected to the adjusting shaft 15 to complete the adjustment work of the adjusting shaft 15.

[0034] In the present invention, the battery 9 of the motor 7 is installed at the tail of the handheld shell 1 to balance the balance of the handheld shell 1. At the same time, the motor 7 and the battery 9 are arranged in a straight line to reduce the handheld diameter of the handheld shell 1 and facilitate handholding.

[0035] In the present invention, the switch of the battery 9 is a self-resetting switch. When the finger is pressed on the switch, the motor 7 of the present application is started. When the finger is released, the motor 7 stops. This setting can not only reduce energy consumption when not in use, but also help the user to aim at the branches first and then start, which is convenient for pruning.

[0036] In some embodiments, since one end of the branch is suspended, during the pruning process, if the suspended end of the branch is not limited, when the movable scissors 2 and the fixed scissors 3 are pruning, the two blades are staggered and it is easy to push the branch out of the pruning blade, resulting in unsuccessful pruning. Therefore, multiple positioning notches 4 are provided on one side of the blade of the fixed scissors 3. During the pruning process, the branch is stuck in the positioning notch 4 and is not easy to slide out from the blade. Therefore, the branch can be cut off without holding the branch with hands.

[0037] In some embodiments, a rubber layer is provided on the outside of the handheld housing 1 to increase friction and prevent it from falling off during use.

[0038] In the present invention, the blades of the movable scissors 2 and the fixed scissors 3 are both arc-shaped. The arrangement of the present application can also reduce the situation where branches slip out of the scissors.

[0039] It can be seen from the above technical solution that when the present application is in use, when fine pruning of wolfberry is required, the present device is held in hand, and the swing drive structure drives the movable scissors 2 to swing back and forth and cooperates with the fixed scissors 3 to cut the wolfberry branches. The present application is light and portable and can shuttle among the wolfberry branches, so pruning is convenient and efficient.
