Description

Technical Field

[0001] The invention belongs to the technical field of pruning tools, and in particular relates to an automatic grape precision flower thinning machine. Background Art

[0002] Most fruit trees produce far more flowers than fruits. Excessive flowering not only consumes a lot of nutrients, but also results in too many fruits, which not only affects the normal development of the fruit, but also forms many small and inferior fruits, weakens the tree, makes it susceptible to diseases, and easily causes alternate years. At the same time, many flowers and fruits will also make the later fruit thinning difficult, labor-intensive, and increase management costs. Therefore, in fruit tree production, it is necessary to remove excess flowers in time to save nutrients, significantly reduce the workload of fruit thinning, and lay the foundation for achieving high quality and low consumption. Most of the flower thinning machines currently used in orchards adopt a blade-type single flower thinning head structure. The operating efficiency of this type of flower thinning machine is low and the operating angle is not easy to adjust.

[0003] At present, most people use flower thinning machines with low efficiency, which are not suitable for grape flower thinning. At the same time, pruning is dangerous when using scissors, and the pruning process is time-consuming and laborious. Summary of the invention

[0022] The cup body (2) is conical.

[0023] The handle (1) is a U-shaped structure.

[0024] like Figure 2As shown, the upper movable cover body mechanism (3) is composed of a cover plate (31), an opening and closing arm (33), a connecting rod (32), a rotating shaft (34), and a sliding rod (35). The cover plate (31) is composed of two symmetrical plates.

The two ends of the sliding rod (35) are respectively connected to a closing arm (33) through a rotating shaft (34). The other ends of the two opening and closing arms (33) are connected to the connecting rod (32) through the rotating shaft (34) and are respectively connected to a symmetrical cover plate (31).

[0025] like Figure 3 As shown, the lower movable cover body mechanism (4) is composed of a cover plate (41), an opening and closing arm (43), a connecting rod (42), a rotating shaft (44), and a sliding rod (45). The cover plate (41) is composed of two symmetrical plates. The closing switch (6) of the handle (1) is connected to the sliding rod (45) of the lower movable cover body mechanism (4) through a linkage rod. The two ends of the sliding rod (45) are respectively connected to a closing arm (43) through a rotating shaft (44).

[0031] The working principle of the present invention is: When working, carry the battery on the back, press the closing switch, and drive the sliding rods of the upper and lower movable cover bodies to slide in the hollow groove of the handle through the linkage rod. The sliding rod drives the opening and closing arms, and drives the sliding rod. Under the action of the rotating shaft, the opening angle of the opening and closing arms changes. The sliding rod pulls the symmetrical cover plates. The symmetrical cover plates are pulled to both sides due to two forces at the pulling end, so that they are squeezed at one point, causing the far ends to separate to both sides, so that the symmetrical cover plates are in an open state. The same is true for the upper and lower covers. Driven by the linkage rod, they are opened at the same time, and the round holes of the upper and lower cover plates are locked. After the upper and lower bunches of the main grapes are trimmed, release the closing switch and reset under the action of the spring. The linkage rod acts in the opposite direction to drive the cover to close. The control power controls the operation of the motor. The motor's disc moves along the spiral groove, and the blade rotating at the front end cuts the flowers that need to be trimmed. The guide wheel guides on the spiral track. When the disc reaches the bottom along the spiral groove, the pruning is completed. Press the closing switch and open the cover to complete one pruning. The next operation is the same. In order to improve the efficiency of flower thinning, the first flower spike is spirally thinned from top to bottom, and the next flower spike is spirally thinned from bottom to top.
